Whole abdominal external beam radiation in the treatment of primary carcinoma of the fallopian tube

Thirty-two patients with adenocarcinoma of the fallopian tube, treated between 1975 and 1990, were studied. Thirteen patients had stage I disease, 9 stage II, and 10 stage III. All patients underwent bilateral salpingo-oophorectomy, total abdominal hysterectomy, and subcolic omentectomy. All patients received postoperative primary whole abdominal external beam radiotherapy. Seventeen patients (53.1%) of the treated group survived NED for at least 5 years. Survival was 76.9% for stage I, 55.6% for stage II, and 20% for stage III. In the Cox multivariate analysis, two variables were independently related to survival: stage of disease and size of residual disease after surgery. Postoperative teleradiotherapy was totally ineffective in gross residual (>2 cm in diameter) disease (0% 5-year NED survivors) and not effective enough in small residual disease (<2 cm in diameter) (33% 5-year NED survivors). Despite postoperative whole abdominal external beam radiotherapy, 3 patients with microscopic, 4 with small, and 4 with gross residual disease did fail within the peritoneal cavity.     

Testicular cancer

The following article provides a comprehensive review of male germ cell tumors; the pathology and the clinical manifestations of the tumors are discussed, as are the modern concepts of clinical staging. Patients with bulky stage II and stage III non-seminomatous germ cell tumors are treated with chemotherapy. The new international classification system has provided a very useful way to categorize these patients by prognosis. Patients with good- or intermediate-risk tumors may be treated with 3 courses of cisplatin, etoposide, and bleomycin (BEP) or 4 courses of etoposide and cisplatin (EP), and more than 90% of these patients will survive. Randomized trials have shown that, if only 3 courses of chemotherapy are to be given, the substitution of carboplatin for cisplatin and the omission of bleomycin are deleterious to outcome. Patients who still have a significant residual mass and normal markers after treatment should undergo a surgical resection of the residual tumor. Patients who are classified by the international classification system as having poor-risk tumors have about a 50% likelihood of survival, and many of these patients will require surgical resection of a residual tumor after chemotherapy. No randomized trial has proved a regimen to be superior to that of 4 courses of BEP. Currently, an ongoing trial is evaluating the effect of the early use of high-dose therapy in combination with hematopoietic rescue in patients with these types of tumors. Patients with small-volume stage II tumors are generally treated with retroperitoneal lymph node dissection (RPLND). About 25% of the patients selected for this procedure will actually have pathologically negative nodes. Those with positive nodes may elect to receive adjuvant chemotherapy (2 courses of BEP), which will almost always prevent relapse. An alternate approach for patients willing to comply with monthly follow-up is surveillance, with chemotherapy deferred until relapse is noted. About 50% of these patients will be cured with surgery (as many as 75% have microscopic disease only). With careful follow-up, those destined to relapse can be treated promptly and at a time when they have small-volume tumors and an excellent prognosis if they go on to receive chemotherapy. Patients with clinical stage I nonseminomatous germ cell tumors may also undergo RPLND, although an acceptable alternative for these patients is surveillance. The advantages and the disadvantages of each approach are discussed. The overall risk of recurrence is about 30%, but there have been patient groups defined that may vary in risk from 10% to 15% up to 50% or more. Patients with advanced seminoma are treated with chemotherapy. When this procedure is used, outcomes are favorable and all patients are either in good- or intermediate-risk groups, according to the international classification system. Patients with small-volume stage II tumors are treated with radiotherapy. Radiation is also generally used for the treatment of clinical stage I patients, although surveillance is growing in prominence as a means to treat these patients. Late effects of treatment are also discussed in this article. Ejaculatory function can be preserved in most patients who have early stage tumors and who undergo RPLND and in some patients who undergo surgery after chemotherapy. The most troubling effect of chemotherapy is the development of etoposide-induced leukemia, a unique--and fortunately rare--clinical entity.     

Chemoprophylaxis for patients with colorectal cancer. Prospective study with five-year follow-up

The effectiveness of a short-term fluorouracil chemopophylaxis regimen commencing four to six weeks after "curative" surgery was evaluated in a homogeneous group of 213 patients with colorectal cancer. In stage III disease (Dukes class C), five-year survival with no evidence of disease (NED) was 24.3% when treated by surgery alone but was 57.5% when a prophylactic regimen of fluorouracil was added (P less than .01), an increase of 33.2%. In stage II disease (Dukes class B), five-year NED survival was raised from 58.5% to 81.6%, an increase of 23.1% (P less than .02). More striking are the one-, two-, and three-year NED survivals in stage III. The one-, two-m and three-year NED survivals for the chemoprophylaxis group are 100%, 95%, and 75%, respectively, in contrast to 70.7%, 48.8%, and 34.1% in the group with surgery alone. The present data indicate that fluorouracil chemoprophylaxis offers a significant improvement of five-year cure rate of patients with stage II and III disease, an overall increase of 28.1% (P less than .01).     

Prognostic factors of primary transitional cell carcinoma of the upper urinary tract

OBJECTIVES: We presented and analyzed our results in order to determine the relationship between patient survival and tumor grade and/or stage. In addition, a retrospective tumor DNA ploidy study was done to evaluate its possible role in predicting future tumor recurrence in the bladder. METHODS: A total of 112 patients with upper urinary tract transitional cell carcinomas (TCCs) were recorded at our hospital. Of these, 68 patients without concurrent bladder tumors (ages ranged from 36 to 80, mean 62.4 years; male:female = 1:1.2) were treated by nephroureterectomy and bladder cuff resection. They were followed up for 14-79 months (average 38.2 months). Eight (36.4%) of the 22 patients who had stage C or D tumors had received adjuvant systemic methotrexate, vinblastine, epirubicin, cisplatin chemotherapy after surgery. DNA flow cytometry using paraffin-blocked tumor specimens was performed on the tumors of 52 patients. RESULTS: Their pathologic stages and grades were 11 at stage 0, 15 at stage A, 20 at stage B, 14 at stage C, 8 at stage D; 9 of grade I, 41 of grade II, and 18 of grade III. Postoperatively, 13 patients (19.1%) subsequently developed bladder tumors with a latent period ranging from 2 to 37 months (average 14.9 months). The difference of the tumor DNA ploidy distribution pattern among tumors of high versus low stages and/or grades is not statistically significant (p > 0.05). Overall, the 5-year survival rates for patients with low- and high-stage tumors were 100 and 66.7%, respectively; for patients with grade I-II and III tumors they were 93.6 and 28.3%, respectively. CONCLUSIONS: Patient survival was mainly related to both tumor stages (p = 0.0037) and grades (p = 0.0001), rather than to tumor DNA ploidy. For patients with grade II upper urinary tract tumors, tumor DNA ploidy seems to provide no additional predictive value on subsequent tumor recurrence in the bladder.     

Intestinal neuronal dysplasia

CONCLUSION: Based on these data we suggest that regional intra-arterial chemotherapy for advanced pancreatic cancer seems not to be superior to common treatment modalities, such as combined radiochemotherapy. BACKGROUND: The prognosis for advanced pancreatic cancer is very poor. No standard treatment is available. Recently, better survival and quality of life was reported from regional cancer treatment via celiac axis infusion. In an attempt to confirm these results we conducted a phase II study of intra-arterial chemotherapy for nonresectable pancreatic cancer. METHODS: From May 1994 to February 1995, 12 consecutive patients with biopsy-proven advanced ductal carcinoma of the exocrine pancreas were given intra-arterial infusions consisting of Mitoxantrone, 5-FU + folinic acid, and Cisplatin via a transfemorally placed catheter in the celiac axis. Six patients were classified as UICC stage III and six as stage IV with the liver as the sole site of distant metastasis. Nine patients had primary and three had recurrent pancreatic carcinoma after a Whipple procedure. Nonresectability of primary tumors was assessed in all patients by laparotomy or laparoscopy. RESULTS: A total of 31 cycles of chemotherapy (mean 2.6 cycles/patient) was administered. Catheter placement was technically feasible in all cycles. A groin hematoma was the only catheter complication. The follow-up by CT scans at 2-mo intervals revealed partial remission in 1 patient (8%), temporary stable disease in 4 patients (33%), and disease progression in 7 patients (58%). The same response was obtained after analyzing the CA 19-9 course. Median survival in stage III patients was 8.5 mo (3-12 mo) and in stage IV patients 5 mo (2-11 mo). Toxicity according to WHO criteria consisted of grade III (4 events), grade II (10 events), and grade I (17 events), mainly resulting from leucopenia and diarrhea/vomiting. Nine of 11 patients experienced temporary relief of pain immediately after regional treatment.     

Prognostic value of nuclear grade of renal cell carcinoma

BACKGROUND: The authors assessed the interest and the value of Fuhrman's nuclear grade as a possible prognostic factor for renal cell carcinoma (RCC). METHODS: An 11-year retrospective study of 190 patients with RCC treated by radical nephrectomy was performed. The distribution by grade was: Grade I, 54 patients; Grade II, 58; Grade III, 58; and Grade IV, 20. The distribution of the patients by tumor stage according to the TNM15 classification was: pT1, 56 patients; pT2, 41; pT3a, 55; pT3b, 25; pT3c + pT3d + pT4b, 5; and pT4a, 8. Significant correlations with other prognostic parameters were noted. Survival curves by grade were evaluated by the Kaplan-Meier method. RESULTS: Nuclear grade was correlated with tumor stage (P = 0.0001), synchronous metastases (P = 0.003), lymph node involvement (P = 0.0001), renal vein involvement (P = 0.0001), tumor size (P = 0.0001), and perirenal fat involvement (P = 0.001). No correlation was found between nuclear grade and tumor multicentricity (P = 0.14) and cell type (P = 0.2). Nuclear grade was an effective parameter in predicting development of distant metastases after nephrectomy. Among the 54 patients who presented with Grade I tumors, only one tumor did metastasize during the 5-year follow-up, whereas 17% of the Grade III and 30% of the Grade IV tumors metastasized. The 5-year actuarial survival rates of the patients with Grade I, II, III, and IV tumors was 76%, 72%, 51%, and 35%, respectively. The comparison of the survival curves by grade showed a statistically significant difference between the curves when Grade I and II tumors were compared with Grade III and IV tumors (P = 0.001). CONCLUSION: In this study, nuclear grade was found to have prognostic significance and seems to be an important criterion when considering the outcome of patients with RCC.     

Survival in ovarian cancer treated in a gynecological department of a central hospital

The characteristics of 73 patients with all stages of epithelial ovarian cancer were retrospectively analysed with emphasis on prognostic factors and survival. The patients underwent total hysterectomy, bilateral oophorectomy and infracolic omentectomy. Efforts were made to reduce the tumor burden as much as possible without endangering the general health status of the patient. Postoperative treatment was cisplatin 60 mg/m2 body surface and cyclophosphamide 50 mg/m2 every four weeks (CP). Patients with low general health status were offered either treosulphane 1 g daily for four weeks alternating with four weeks without treatment, or no treatment. Patients in FIGO stage IA and B generally received no postoperative chemotherapy treatment. Fifteen percent were in FIGO stage I, 7% in stage II, 5% in stage III and 23% in stage IV. Fifteen patients could be radically operated, however, only three patients who were in stage III. Fifty-four patients were treated with CP, 11 with treosulphane and eight patients did not receive postoperative treatment. In 28 patients second look laparotomy was performed. Only six patients had a complete pathological response, two of these in stage III. Stage and tumour grade could be identified as prognostic factors. Three-year survival was 70% in stage I, 67% in stage II, 28% in stage III and 0% in stage IV. Survival in 43 patients in stage III and IV was statistically compared to 265 patients from a prospective, randomized study by the Danish Ovarian Cancer Group (DACOVA), comparing cyclophosamide and cisplatin with and without doxorubicin. We found no statistical difference in survival between patients in our material and the DACOVA-material except in patients with low grade tumours whose survival in the CAP-arm of the DACOVA-study was superior. The rate of complete pathological response was significantly better in the DACOVA-study.     

Kaposi''s sarcoma-associated herpesvirus (KSHV)/human herpesvirus 8 (HHV8)--a new human tumour virus

A retrospective analysis of 22 patients with ovarian dysgerminoma who were treated between 1980 and 1987 was carried out. The median age at presentation was 24.5 years. A total of 15 patients were in stage I, one patient was in stage II and six patients were in stage III. Bilateral ovarian involvement was present in four patients. Conservative surgery was carried out in nine patients and 11 patients underwent radical surgery. Two patients had biopsy only. Fourteen patients received adjuvant radiotherapy and three patients received salvage radiation for recurrent disease. The 10-year actuarial survival rate was 81.8%. All 15 patients in stage I were alive and disease-free at a median follow-up of 125 months. Four patients (one in stage II and three in stage III) died of progressive or recurrent abdominopelvic disease. Pelvic recurrence occurred after conservative surgery in two patients in stage IA who had a tumour size greater than 10 cm, but they were salvaged with radical surgery, chemotherapy and radiotherapy. There were seven patients aged 20 years or less. All were alive and disease-free at a median follow-up of 127 months.     

Progressive asymmetrical peripheral neuropathy of both legs in a 64-year-old man

Between August 1983 and April 1996, 53 testicular germ cell tumors in 52 patients were treated at Toranomon Hospital. The average age of the patients was 36.1 years (range 21-89). The affected side was the right side in 24, left in 27 and bilateral in 1 case. Of the 53 tumors 34 (64.2%) were seminoma and 19 (35.8%) were non-seminomatous germ cell tumor (NSGCT). High ligation orchiectomy was performed in all cases. Of 29 stage I seminomas, post-operative adjuvant radiotherapy was performed in 6 cases prior to 1991. None of these tumors recurred. Two cases of relapses (8.7%) were found among the 23 stage I seminomas followed by surveillance. Of 8 stage I NSGCTs followed by surveillance, 4 (50.0%) tumors which contained embryonal carcinoma element and vascular invasion relapsed within 12 months after orchiectomy. A case of stage IIA seminoma was treated successfully by irradiation. Seven cases of stage II (3 seminomas and 4 NSGCTs) and 8 cases of stage III (1 seminoma and 7 NSGCTs) as well as cases of 6 stage I patients who developed relapse during surveillance were treated by VAB-6 chemotherapy. Of these 21 cases, 11 (52.4%) achieved complete response (CR) and 10 (47.6%) partial response (PR). Salvage surgery and/or additional chemotherapy was successful to bring the 10 PR cases into CR condition. One NSGCT patient, however, died of electrolyte imbalance during the maintenance chemotherapy for disease progression after achieving CR. All 34 patients with seminomas and 18 of the 19 with NSGCTs were alive without evidence of disease after a mean follow up period of 61.1 months (range 4-150 months).     

Characteristics of rare ovarian tumors--possibilities of organ preservation

Whereas 65-70% of ovarian malignancies are of the epithelial type, the occurrence rate of stromal tumors is of approx. 7% and that of germ cell tumors of approx. 15%. Stromal tumors are mostly of the granulosa cell type, whereas germ cell tumors occur mainly as dysgerminoma (occurrence 0.9-2%), endodermal sinus tumors, or teratoma. Organ preservation is discussed in relation to the characteristics of these special tumor types. Granulosa cell tumors, representing 70% of the tumors of the gonadal stroma, occur unilaterally in approx. 97% of cases. 10-year-survival in stage I is over 90%. In stages II and III a complete remission after chemotherapy (acc. to the PVB, VAC, or BEP protocol) may be achieved in approx. 60% of cases. Due to these characteristics organ preservation seems feasible. Since dysgerminoma represent the most common malignant germ cell tumor in children, adolescents and pregnant women (up to 17% of all dysgerminoma are diagnosed during pregnancy), the wish for organ preservation is the more understandable. However, bilaterality, occurring in 20% of cases, has to be considered. Especially in large tumors lymphatic metastases also have to be taken into account. In cases of endodermal sinus tumors and teratoma, overall survival, mainly in patients with advanced disease, depends on the response to an aggressive chemotherapy. Preconditions for organ preservation are the patients' urgent childbearing desire, their information concerning the 5-7% risk of recurrence, an adequate oncologic postoperative care and optimally, after delivery, removal of the contralateral ovary and re-staging. The operative procedure requires removal of the corresponding adnexa, wedge dissection of the contralateral ovary, omentectomy, and depending on the histological tumor type a pelvic, possibly paraaortal lymph node dissection. No generally accepted standards are available for organ preserving surgery of stromal tumors, especially of the granulosa cell type. Prognosis is essentially influenced by a possible rupture being present, tumor size, cellular atypia, and the mitotic index. If one takes into consideration the possibility of lymph node metastases, at least a pelvic lymph node dissection should be recommended. In cases of metastases additionally a chemotherapy (VAC protocol) is indicated. Among germ cell tumors, dysgerminoma and non-dysgerminoma are treated differently. Non-dysgerminoma are endodermal sinus tumors, teratoma, embryonal carcinoma and mixed forms. For both groups operative management may aim at tumor reduction and in principle organ preservation. Whereas for dysgerminoma an adjuvant radiation therapy is feasible, in cases of non-dysgerminoma the response to a chemotherapy is the only factor influencing prognosis. Chemotherapy as adjuvant treatment is not indicated for pure dysgerminoma stage Ia, and pure solid teratoma stage Ia Gl. For all other dysgerminoma adjuvant chemotherapy, VAC protocol, and chemotherapy according the the BEP protocol for non-dysgerminoma is recommended. In cases of metastatic spread, in both groups an aggressive chemotherapy (BEP protocol) is most commonly performed.     

Characterized allergens causing bakers'' asthma

OBJECTIVE: Surveillance after orchiectomy alone becomes popular for the management of clinical stage I nonseminomatous germ cell testicular tumours (CS I NSGCTT). Effort to identify patients at high risk of relapse leads to searching prognostic factors of CS I NSGCTT. The aim of this study was to identify those patients in whom a surveillance policy is less likely to be successful. PATIENTS AND RESULTS: Seventy-two CS I NSGCTT patients were stratified to different risk-adapted therapeutic approaches according to histopathologic findings of primary tumor removed by inguinal orchiectomy. Eighteen patients (group A) with vascular invasion and majority of embryonal carcinoma component in the primary tumor were treated with adjuvant BEP chemotherapy. None of them experienced disease progression after a median follow-up period of 36 months after orchiectomy. Five patients (group B) with vascular invasion and the majority of teratomatous elements in the primary tumor have been followed up 56 months after orchiectomy. They were treated with primary retroperitoneal lymph node dissection (RPLND). Two of them (40%) had pathologic stage II after RPLND and underwent subsequent chemotherapy. One of them died due to disease progression 29 months following orchiectomy. Another one lives with no evidence of disease (NED). Three patients in pathologic stage I are alive with NED. Forth-nine patients (group C) without vascular invasion have been followed up for a median duration of 37 months after orchiectomy. They were kept under close surveillance, consisted of regular follow-up with tumor markers, chest x-ray and CT of the retroperitoneum. Disease progression was observed in 7 (14.3%) patients after a median duration of 8 months after orchiectomy. They were treated with BEP chemotherapy and live with disease-free median survival of 22 months after completion of therapy. The overall survival rate of all 72 patients was 98.6%. The median survival for all patients was 37 months (range 7-73). CONCLUSIONS: The authors will continue to use surveillance policy only in patients without vascular invasion in the primary tumor.     

A phase II study of gemcitabine in platinum pre-treated patients with advanced epithelial ovarian cancer

BACKGROUND: Most patients with advanced ovarian cancer will relapse following platinum-based combination chemotherapy and be considered for second-line treatment. Gemcitabine, a nucleoside analogue, is active against a range of solid tumors. This phase II study investigated the activity of single-agent gemcitabine in patients with recurrent ovarian cancer. PATIENTS AND METHODS: Thirty-eight patients with FIGO stage III (34%) or IV (64%) ovarian cancer who were previously treated with platinum-containing regimens were enrolled. Patients received 1200 mg/m2 gemcitabine on days 1, 8 and 15 of a 28-day cycle. RESULTS: Patients completed an average of 3.6 cycles. Two complete and three partial responses were seen in 36 evaluable patients, for an overall response rate of 13.9% (95% CI: 4.7%-29.5%). The median survival time was 6.7 months. Toxicities were generally mild. The most common were grade 3-4 neutropenia and grade 3 leukopenia reported in 23.7% and 10.5% of patients, respectively. One patient had grade 4 pulmonary toxicity. CONCLUSION: Single-agent gemcitabine is active and well tolerated in patients with recurrent ovarian cancer.     

Penile cancer in Taiwan--20 years' experience at National Taiwan University Hospital

To analyze the characteristics and prognostic factors of penile cancer in Taiwanese, we retrospectively reviewed the clinical data of patients with a diagnosis of penile cancer treated during a 20-year period (1977-1996) at National Taiwan University Hospital (NTUH). Of 71 patients treated for penile cancer during the study period, 17 were referred from other hospitals or clinics. Our analyses focused on the 54 previously untreated patients. Growth on the penis was the main symptom in all cases. Palpable inguinal lymph nodes were found only in 14 patients. All 54 patients with primary tumors were treated surgically. Pathologic examination showed squamous cell carcinoma (SCC) in 43 cases, extra-mammary Paget's disease in three, verrucous carcinoma in three, Bowen's disease in two, cutaneous lymphoma in two and basal cell carcinoma in one. Twenty-six (48%) patients had stage I penile cancer, 13 (24%) had stage II, seven (13%) had stage III, and eight (15%) had stage IV cancer. The five-year survival rate was 78% among patients with SCC and 84% among those with nonsquamous malignancies (p = 0.80). The five-year cumulative survival rates according to Jackson's cancer stage were 100% for patients with stage I, 88.9% for those with stage II, 66.7% for those with stage III, and 0% for those with stage IV (p < 0.001). Tumor staging (p = 0.027) and adjuvant chemotherapy (p = 0.042) were found to be the most significant prognostic factors. Penile cancer accounted for 0.254% of all malignancies among male patients at the NTUH during the study period. Our findings indicate that penile cancer is uncommon in Taiwanese and its prognosis is closely related to tumor staging and management. Early diagnosis and appropriate treatment may lead to prolonged survival.     

High-dosage chemotherapy and the autologous transplantation of peripheral hematopoietic progenitor cells in breast cancer: the initial results, analysis of toxicity and the necessary support means

BACKGROUND: In the last years high dose chemotherapy (HDC) schedules have been developed with autologous bone marrow transplantation (ABMT) which are very effective in breast cancer. Expectation has been raised concerning the cure of a subgroup of patients with metastatic breast cancer and the improvement of prognosis in high risk stages II and III. METHODS: CTCb (cyclophosphamide 6 g/m2, thiotepa 500 mg/m2 and carboplatin 800 mg/m2) was administered with autologous peripheral hematopoietic progenitor cells transplantation (TACPHP) and granulocytic colony stimulating factor (G-CSF) 5 micrograms/kg/day to 27 patients with breast cancer: 9 in stage IV in complete remission, 12 in stage II with > or = 10 affected lymph nodes and 6 in stage III. RESULTS: No toxic deaths were reported. The median time to achieve > or = 0.5 x 10(9) neutrophils/l was 8 days, to > or = 20 x 10(9) platelets/l 9 days and to > or = 50 x 10(9) platelets/l 12 days. Fever was observed in 85% of the patients although its median duration was of only one day. Extrahematologic toxicity was moderate with grade III nausea/vomiting in 48% of patients, grade III mucositis in 22%, grade III hepatitis in 19%, and grade III diarrhea in 4%. No grade IV toxicity was observed. The median follow-up is still short (10 months, range: 2-25). All the patients maintain normal hematologic peripheral blood counts and only 4 (in stage IV) have relapsed. CONCLUSIONS: The slight extrahematologic toxicity observed in the high dose chemotherapy with cyclophosphamide, thiotepa and carboplatin, and the rapid hematologic recovery provided by the TACPHP and G-CSF allow the above schedule to be administered with moderate toxicity and no mortality. This low toxic profile leads to the possibility of future trials with this chemotherapy schedule in other subgroups of patients with breast cancer.     

Clinical features of epithelial ovarian cancer in young reproductive women

A 10-year retrospective review of epithelial carcinoma of the ovary was performed about 95 patients which were diagnosed and treated at the Oita Medical University Hospital. The patients' ages at the first diagnosis ranged from 15 to 85 years with a mean of 51.6 years. Twenty-two of 95 patients (23.2%) were below the age of 40. Most patients analysed in this study complained of lower abdominal pain, lower abdominal mass, and/or lower abdominal fullness. Sixteen of 22 patients under the age of 40 (72.7%) and 27 of 73 patients over the age of 40 (37.0%) were diagnosed as having mucinous cystadenocarcinoma. The incidence of mucinous cystadenocarcinoma below the age of 40 was significantly higher than that over the age of 40 (p < 0.005, chi 2-test). Eleven patients below the age of 40 had FIGO stage Ia grade 1 disease and 2 of these patients were pregnant. The incidence of stage Ia disease under the age of 40 was significantly higher than that over the age of 40 (p < 0.005, chi 2-test). Both pregnant patients and 5 other patients with stage Ia disease were treated with only unilateral salpingo-oophorectomy. All patient with stage Ia disease had no evidence of recurrence within 5 years. This suggests that conservative surgery may be considered as the treatment for the FIGO stage Ia grade 1 ovarian cancer.     

Postchemotherapy retroperitoneal lymph node dissection is effective therapy in selected patients with elevated tumor markers after primary chemotherapy alone

OBJECTIVES: Elevated tumor markers after primary chemotherapy for metastatic testis cancer are usually an indication of persistent cancer. Subsequent treatment has usually been salvage chemotherapy. This article examines the possibility that selected patients can achieve long-term disease-free survival with surgery alone. METHODS: Using a computerized data base of 627 postinduction chemotherapy retroperitoneal lymph node dissections (PC-RPLND), 23 patients with elevated tumor markers who have undergone PC-RPLND after induction chemotherapy alone were identified. Of the 23 patients, 15 were considered candidates for salvage chemotherapy, but instead underwent salvage surgery. Case histories were reviewed to establish selection criteria for PC-RPLND. RESULTS: Eight patients originally presented as clinical Stage C, 6 as clinical Stage B-3, and 1 as clinical Stage B-2. All patients initially received cisplatin combination chemotherapy. Twelve patients had an elevated alpha-fetoprotein level and 3 patients had an elevated beta human chorionic gonadotropin level prior to PC-RPLND. Seven patients had rising markers at the time of PC-RPLND. Seven patients had teratoma only in their resected specimen and all have no evidence of disease (NED) at a median of 35 months. Two patients had necrosis only in their RPLND specimen and both are NED at 10 and 42 months. Six patients had cancer in their resected specimen and 2 are NED, 1 is alive with disease, and 3 are dead of disease. Five of the 6 patients with cancer in their resected specimen were the only patients who received postoperative chemotherapy. CONCLUSIONS: Some patients with modest elevations of tumor markers after induction chemotherapy may only have teratoma or necrosis in the postchemotherapy resected specimen. These patients (n = 9) remain continuously NED. Patients who undergo salvage surgery and have cancer in the resected specimen do less well, but selected patients can be cured with this modality and thus avoid the morbidity of salvage chemotherapy.     

An early phase II trial combining cisplatin and carboplatin in advanced non-small cell lung cancer

We conducted an early phase II trial in advanced non-small cell lung cancer (NSCLC) to evaluate response efficacy of a combination of Cisplatin (CDDP) and Carboplatin (CBDCA). The twenty-six patients in the study had had no previous treatment. They received a sequential administration of 300 mg/m2 CBDCA and 80 mg/m2 CDDP with approximately 3,500 ml of hydration on day 1 every 4 weeks. All patients were evaluable for response and toxicity. Ten (38.5%) of all assessable patients achieved a partial response (95% confidence interval, 19.8-57.2%). Response rates for patients with stage III A, III B and IV- disease were 40.0 (2/5), 70.0 (7/10) and 9.1% (1/11), respectively. Response rates for patients with squamous cell carcinoma, adenocarcinoma and large cell carcinoma were 35.7 (5/14), 45.5 (5/11) and 0.0% (0/1), respectively. The median survival time (MST) of all patients was 11 months. The MST for patients with stage III disease was 14 months; for those with stage IV disease it was 7 months. The MST for responding patients was 15 months and for not responding patients 5 months. Major toxicities were hematologic and gastrointestinal, and the dose-limiting factor was thrombocytopenia. This combination chemotherapy was effective against NSCLC with tolerable toxicities. Further trials are warranted to determine the efficacy of the combination chemotherapy.     

Lipoprotein lipase expression exclusively in liver. A mouse model for metabolism in the neonatal period and during cachexia

BACKGROUND: Most published series of ovarian carcinoma find a correlation between histologic grade and survival, but the grading system used commonly is not specified, and several different systems exist, some of which use different criteria for different histologic types. However, several studies have shown marked interobserver variability in distinguishing among the histologic types of ovarian carcinoma. The authors attempted to derive a universal grading system for all invasive ovarian carcinomas (IOC), based on the Nottingham system for grading all types of mammary carcinoma. METHODS: The authors studied 461 patients with IOC of different histologic types and clinicopathologic stages who were treated in a uniform manner between 1980 and 1994 with surgery and cisplatin-based chemotherapy. All slides were reviewed and the tumors graded as follows: Architectural pattern (predominant): Glandular = 1, Papillary = 2, and Solid = 3; Nuclear pleomorphism: Slight = 1, Moderate = 2, and Marked = 3; Mitotic activity (mitotic figures per 10 high-power fields [1 HPF = 0.345 mm2]) in most active region: 0-9 = 1, 10-24 = 2, and > or = 25 = 3; Grade 1 = total score (adding three values obtained earlier) 3-5, Grade 2 = 6 or 7, and Grade 3 = 8 or 9. RESULTS: Tumor grade correlated with survival in both early and advanced stage disease and for all major histologic types of IOC except clear cell carcinoma (CCC). Results for CCC approached but did not reach clinical significance. By multivariate analysis, only this tumor grade and performance status were significant in Stage I/II IOC. For Stage III/IV tumors, the new tumor grade also was significant, as were performance status, residual tumor size, response to chemotherapy, and mucinous (unfavorable) or transitional cell (favorable) histologic type. International Federation of Gynecology and Obstetrics grade (based primarily on architectural features) did not correlate significantly with survival except in Stage III/IV serous and Stage I/II mucinous carcinomas. CONCLUSIONS: The new grading system reported is simple, reproducible (among the current study authors), and useful for all histologic types and clinical stages of IOC. Further testing for reproducibility and clinical utility is recommended.     

The role of cell communication in the pathogenesis of breast cancer]

OBJECTIVE: The aim of the study is to analyse long-term results of patients with small cell lung cancer (SCLC) treated at the same institution according to a prospective study including surgery, chemotherapy, and radiotherapy. METHODS: From 1981 to 1995, 104 patients with a proven histology of SCLC underwent surgery, chemotherapy, and radiotherapy. Fifty-one patients with operable stage I or II lesion received surgical resection followed by adjuvant chemotherapy and radiotherapy. Fifty-three patients with proved SCLC and clinical stage III received induction chemotherapy followed by surgery and radiotherapy. All patients received from four to six courses of chemotherapy and 36 had prophylactic cranial irradiation (PCI). All patients had follow-up for at least 1 year, and survival time was calculated from the date of the diagnosis until death or most recent follow-up. RESULTS: Ninety-six patients were male and eight female. We performed 29 pneumonectomies, eight bilobectomies, 66 lobectomies and one no resection. Regarding the clinical stage, 35 patients (33.6%) had stage I, 16 patients (15.4%) had stage II and 53 (51%) had stage III. Post-operative pathologic staging revealed stage I in 37 patients (35.6%), stage II in nine patients (8.6%), stage III in 45 patients (43.3%), and in 13 patients (12.5%) there was no more tumor. The 30-day mortality was 2% (two patients). Fourteen patients (13.4%) had post-operative complications. Fifty-one patients (49%) had a relapse. The median follow-up was 55 months. Twenty-six patients remain alive and 78 patients have died. The overall 5-year survival rate was 32%, with an estimate median survival time of 28 months; according to the pathologic stage, the survival data were 52.2%, 30% and 15.3% for stage I, II and III, respectively (P < 0.001). The 5-year survival was 41% in patients without SCLC after chemotherapy. CONCLUSION: As with non-small cell lung cancer, survival following surgery and chemotherapy clearly correlates with the stage. At present, it is not clear whether surgery is truly effective for patients with SCLC. In our experience, the complete elimination of small cell lung cancer is associated with an improvement in survival (41% at 5 years).     

Paclitaxel in combination chemotherapy with radiotherapy in patients with unresectable stage III non-small-cell lung cancer

PURPOSE: The addition of combination chemotherapy to standard radiation therapy has improved treatment for locally unresectable non-small-cell lung cancer. In this phase II study, we evaluated the toxicity and efficacy of a novel chemotherapy regimen that included paclitaxel, cisplatin, and etoposide plus concurrent radiation therapy in this group of patients. PATIENTS AND METHODS: Thirty-three patients with previously untreated, unresectable stage III non-small-cell lung cancer (stage IIIA, 11 patients; stage IIIB, 22 patients) initially received two courses of chemotherapy, which included paclitaxel 135 mg/m2 by 1-hour infusion on day 1, cisplatin 60 mg/m/ intravenously (i.v.) on day 2, and etoposide 100 mg/m2 i.v. on days 1, 2 and 3. On week 6, radiation therapy (60 Gy in 30 fractions) was initiated in conjunction with two additional courses of chemotherapy: paclitaxel 135 mg/m2 i.v. by 1-hour infusion on day 1, cisplatin 5 mg/m2 i.v. on days 2- to 10, and etoposide 25 mg/m2 on days 1 to 10. RESULTS: This combined modality program was feasible and well tolerated by most patients. During the two courses of induction chemotherapy, grade 3 or 4 myelosuppression occurred in only six patients (18%). Esophagitis was common during combined modality therapy (grade 3, 10 patients; grade 4 five patients). Forty-two percent of patients had partial response after two courses of induction therapy, and 82% of patients had an objective response at completion of therapy. Twelve patients (36%) had a complete response. Nineteen patients remain progression-free at a median of 8 months; the median survival time has not been reached. CONCLUSION: This paclitaxel-containing combined modality therapy is feasible and highly active in patients with inoperable stage III lung cancer. Esophagitis is the most common severe toxicity with this program. Further studies with paclitaxel-containing combination regimens in patients with stage III non-small-cell lung cancer are indicated.
