Treatment of a habitual smoker using nicotine gum: a case report

39 untreated patients with local cancer of the bladder without distal metastases were included in the trial to assess efficacy of combined drug plus radiation treatment, its toxicity and chances to preserve the bladder. The examination comprised tumor biopsy, ultrasonography, computed tomography, excretory urography and routine laboratory tests. The patients received one or two courses of intraarterial chemotherapy, radiation (50 Gy) and two doses of cysplatinum in a dose 70 mg/m2 before and after radiation. A complete response was achieved in 66.6%, partial in 12.8%, stabilization in 10.3% and progression in 10.3% of patients. One-year survival was reported in 89.7%, recurrence-free survival with functioning bladder being 66.7%. Side effects were mild and did not demand the treatment discontinuation.     

Combination chemotherapy with cis-platinum and ifosfamide for hormone unresponsive prostate cancer

PURPOSE: There is no effective therapy against hormone refractory prostate cancer. This led us to evaluate the effectiveness and toxicity of cis-platinum (CDDP) and ifosfamide (IFM) combination chemotherapy in the patients with hormone-unresponsive carcinoma of the prostate. METHODS: Patients with hormone-unresponsive prostate cancer were scheduled to receive CDDP 70 mg/m2 intravenously on day 1 and IFM 1.2 g/m2/day intravenously on day 1 through day 5 of 28-day cycle. RESULTS: Twenty seven patients with hormone unresponsive prostate cancer were enrolled onto this trial. Of these patients, seven (26%) demonstrated a partial objective response (PR), and ten (37%) a stable disease (ST). The response duration of PR cases lasted from 6 to 49 months with a median of 16 months and the response duration of PR + ST cases lasted from 3 to 36 months with a median of 10 months. Subjective improvement was obtained in 11 patients (41%). Survival duration of all cases were 4 to 89 months with a median of 23 months and probabilities of survival at 3 years and 5 years were 36% and 24%, respectively. The toxicity of this treatment was mostly mild to moderate, anemia (96%), leukocytopenia (89%), anorexia (81%), alopecia (67%), thrombocytopenia (44%), hematuria (38%), renal dysfunction (19%) and liver dysfunction (7%) were noticed. Severe toxicity was observed in two cases, one acute renal failure and one endotoxin shock. CONCLUSION: We conclude that CDDP and IFM combination chemotherapy was active regimen for hormone unresponsive prostate cancer.     

Evaluation of intra-arterial infusion chemotherapy for advanced gastric cancer

We evaluated the therapeutic efficacy of intraarterial infusion chemotherapy in advanced gastric cancer, its side effect and patient prognosis, in comparison with systemic infusion. Of 125 cases of advanced gastric cancer, 41 cases received intraarterial chemotherapy (A group) and the rest were given systemic infusion (S group). Protocols of chemotherapy were 5-FU + MTX in 49 cases, 5-FU + cisplatin in 62, and 5-FU + MMC in 14. Location of the disease was the peritoneum in 69 cases, nodes in 59, liver in 38, and other sites, 33. The response rate of A group was significantly higher than that of S group, at 31% and 13% respectively. Although 41% of cases showed side effects (> or = grade 2), there was no significant difference between the 2 groups. The median survival period and 1-year survival rate were 8.4 months and 35%, respectively, and there was no significant difference between the 2 groups. In cases with liver metastasis, the prognosis of A group was better than that of S group. The results suggest that intra-arterial infusion chemotherapy is an effective treatment for liver metastasis from gastric cancer.     

Sequential intrahepatic fluorodeoxyuridine and systemic fluorouracil plus leucovorin for the treatment of metastatic colorectal cancer confined to the liver

PURPOSE: Extrahepatic metastasis represents a frequent pattern of disease progression when fluorodeoxyuridine (FUDR) is given by the intraarterial route for the treatment of unresectable colorectal liver metastases. Systemic fluorouracil (5-FU) plus leucovorin was added to intrahepatic FUDR to prolong the duration of disease control. METHODS: Only patients with colorectal cancer who had evidence of unresectable metastases confined to the liver were eligible. Laparotomy was performed to establish arterial perfusion of the liver. Cycles of intrahepatic FUDR followed by a 1-week rest period then intravenous chemotherapy with 5-FU plus leucovorin were administered until maximal regression of hepatic metastases. Maintenance chemotherapy with 5-FU plus leucovorin was then given until disease progression. RESULTS: Fifty-seven patients entered this trial; four patients (7%) were ineligible and 13 (23%) did not receive any chemotherapy on study because of findings at laparotomy. The 40 eligible patients who began chemotherapy are included in the statistical analyses. Twenty-five patients (62% of those who received chemotherapy) experienced regression of liver metastases. The median time to tumor progression was 9 months, but only 3% remained progression-free at 24 months. The median survival duration was 18 months. Toxicity was tolerable with no cases of biliary sclerosis. One treatment-related fatality due to sepsis was observed. CONCLUSION: Although short-term treatment results appear to be somewhat better than we have previously observed with intrahepatic FUDR alone, the sequential regimen did not have an impact on long-term, progression-free survival in patients with unresectable liver metastases. We are now investigating this regimen as surgical adjuvant therapy in selected patients following hepatic metastasectomy where this aggressive approach might have a greater therapeutic effect in the minimal residual disease setting.     

Effect of UFT on treatment of urological cancer--effect of UFT on treatment of invasive bladder cancer and advanced prostate cancer. Ibaraki Urological Cancer Chemotherapy Study Group

A prospective randomized joint study was conducted to evaluate the usefulness of UFT 1) as a postoperative adjuvant therapy in patients with invasive bladder cancer who had undergone curative combination therapy with operation and/or chemotherapy and/or radiation therapy, 2) as an endocrine chemotherapy in patients with newly diagnosed stage C/D prostate cancer, for a period of 3 years from January, 1992. For bladder cancer, of 36 patients with invasive bladder cancer, clinically cured by combination therapy, 20 patients were treated with UFT as an adjuvant chemotherapy over 12 months, and they were compared to 16 patients with no adjuvant therapy. After excluding 10 inappropriate patients, 12 patients in the UFT treatment group and 14 patients with no adjuvant treatment group were observed. For prostate cancer, of 29 patients with clinically stage C/D prostate cancer, 13 were treated with endocrine therapy in combination with UFT, and 16 patients were treated with endocrine therapy alone. After excluding 7 inappropriate patients, 10 patients with endocrine chemotherapy and 12 patients with hormonal therapy were observed. The non-recurrence rate, survival rate and side effects of UFT were evaluated. In the study of bladder cancer, neither a significant difference of non-recurrent rate nor of survival rate was seen between the two groups. In the study of prostate cancer, neither a significant difference of non-recurrent rate nor of survival rate was seen between the two groups. These findings suggest UFT is less useful as an adjuvant therapy for the invasive bladder cancer and as an endocrine chemotherapy for newly diagnosed advanced prostate cancer.     

Internal radiation therapy for patients with primary or metastatic hepatic cancer: a review

BACKGROUND: The limited efficacy of current approaches to the treatment of patients with hepatic cancer, including external beam radiation therapy and cytotoxic chemotherapy, has reawakened interest in the use of internal radiation therapy. METHODS: The authors reviewed series of patients with liver metastases or hepatocellular carcinoma (HCC) treated with 1) interstitial irradiation and direct intratumoral injection of 90Y microspheres, 2) intraarterial infusion of (131)I-Lipiodol, 3) intraarterial infusion of 90Y microspheres, or 4) parenteral administration of radiolabeled monoclonal antibodies. RESULTS: High dose rate interstitial irradiation with afterloading of (192)Ir resulted in local control of hepatic metastases for a median of 8 months and complete tumor eradication in 2 patients. Direct intratumoral injection of 90Y microspheres reduced the size of 90.6% of tumors and completely destroyed them in 8 patients. Treatment with arterial (131)I-Lipiodol resulted in a 17-92% response rate as well as a case of complete remission of unresectable HCC. It was found to be most effective against small tumors. No response was observed with liver metastases from colorectal carcinoma. Partial response was commonly achieved when patients with unresectable liver metastases or HCC were treated with intraarterial 9OY microspheres. Among four patients whose HCC became resectable following treatment with 90Y microspheres, two cases of complete remission were documented. In a prospective randomized trial, (131)I-antiferritin combined with chemotherapy was no more effective than chemotherapy alone. CONCLUSIONS: The different approaches to internal radiation therapy that are reviewed in this article represent several ways in which radiation can be selectively targeted to hepatic tumors without undue radiation to the nontumorous liver. However, the efficacy of each of these therapies still needs to be evaluated in randomized controlled trials.     

Endothelin-1 concentrations and optimisation of arterial oxygenation and venous admixture by selective pulmonary artery infusion of prostaglandin E1 during thoracotomy

PURPOSE: To demonstrate a superselective intraarterial chemotherapy as a therapeutic alternative in the treatment of previously treated recurrent lymph node metastases in breast cancer. METHODS: 14 patients with recurrent lymph node metastases in cases of breast cancer were presented to be treated by intraarterial chemotherapy of 25 mg mitoxantrone/m2 over a period of 24 hours. In two patients with superclavicular lymph node involvement an intraarterial therapy could not be carried out because of a vascular connection to the anterior spinal artery. Involved lymph stations could be reached in superselective technique by side branches of the subclavian artery. Heparin coverage was given intravenously. Every patient had had surgery, radiation, systemic chemo- and hormonal therapy before and was now graded as inoperable. Therapy indication was given by local tumour-induced symptoms. RESULTS: In the 12 treated cases complete remission was seen in three, partial remission in 4, a steady state in two and a progressive disease in three. There were no complications or severe side effects. CONCLUSION: Intraarterial chemotherapy is an effective and well tolerated treatment in recurrent lymph node metastases in cases of breast cancer even if conventional therapies can no longer be used.     

Treatment of ocular melanoma metastatic to the liver by hepatic arterial chemotherapy

PURPOSE: Ocular melanoma is characterized by a high rate of liver metastases and is associated with a median survival time less than 5 months. There is no standard treatment available. Treatment strategies have, without success, relied on the experience with metastatic cutaneous melanoma. The only effective treatment is chemoembolization using cisplatin and polyvinyl sponge, which has never become accepted on a large scale. The objective of the study was to establish prospectively the efficacy and toxicity of hepatic intraarterial fotemustine, a third-generation nitrosourea, in patients with liver metastases from ocular melanoma. PATIENTS AND METHODS: Thirty-one patients were subjected to laparotomy to place a totally implantable catheter into the hepatic artery and received fotemustine 100 mg/m2 as a 4-hour infusion, first once a week for four times and then, after a 5-week rest period, every 3 weeks until progression or toxicity. Cox regression models were used to assess the prognostic role of patient survival characteristics. RESULTS: Objective responses were observed in 12 of 30 assessable patients (40%; 95% confidence interval, 22% to 59%). The median duration of response was 11 months and the median overall survival time, 14 months. Lactate dehydrogenase (LDH) appeared to be the strongest prognostic factor for survival. Toxicity was minimal and treatment could be administered on an outpatient basis. CONCLUSION: The results of hepatic arterial chemotherapy with fotemustine produced a high response rate and survival similar to chemoembolization therapy. It involves no major toxicity and preserves the quality of life. To assess further its effectiveness, a randomized study to compare hepatic intraarterial versus intravenous chemotherapy is being planned.     

The fate of patients with locally advanced bladder cancer treated conservatively with neoadjuvant chemotherapy, extensive transurethral resection and radiotherapy: 10-year experience

PURPOSE: We assess the results of bladder preservation for infiltrating bladder cancer. The potential for neoadjuvant chemotherapy followed by extensive transurethral resection and radiotherapy was evaluated in 40 patients with T2-T4a G2-G3 bladder carcinoma. MATERIALS AND METHODS: From 1983 to 1995, 40 patients with bladder cancer underwent bladder sparing treatment, consisting of neoadjuvant chemotherapy, extensive transurethral resection and radiotherapy. Most patients had T3G3 cancer. A deep transurethral resection biopsy was performed before and after chemotherapy, and an extensive transurethral resection was repeated at the end of radiotherapy. Of the patients 30 received cisplatin and methotrexate and 10 also received vinblastine. Total dose of radiotherapy was 60 to 65 Gy. Recurrent superficial tumors were treated transurethrally. Radical cystectomy was considered for persistent or recurrent invasive disease. RESULTS: Complete response occurred in 19 patients (47.5%) after chemotherapy, and in 8 patients after transurethral resection and radiotherapy (67.5%). Within 10 years 8 responding patients (30%) had local recurrences and 3 underwent cystectomy. Of the patients 14 (35%) are alive, including 13 with no evidence of disease (mean survival 65 months), 5 died of unrelated disease and 21 (52.5%) died of distant metastases (mean survival 28 months). Of the 21 patients 14 had residual tumor after radiotherapy, 3 presented with distant metastases after vesical infiltrating recurrence and 4 had distant metastases in the absence of locoregional recurrence. In 22 patients (55%) the bladder was salvaged. Patients with complete response to chemotherapy had a low risk for recurrent infiltrating tumors and metastases. CONCLUSIONS: Complete tumor control was maintained at 5 years in more than 50% of the patients treated conservatively. Bladder salvage is feasible in select patients.     

America: where kids are getting killed

Two cases of liver metastasis from colon cancer were treated by percutaneous ethanol (PEI) and acetic acid (PAI) injection for the recurrent lesion after surgery. Case 1 was a 60-year-old female who received sigmoidectomy with partial hepatectomy, and intraarterial 5-FU infusion was done after surgery. One year later, recurrence of liver tumor was detected, and PEI and PAI were performed for the metastatic lesions of the liver. Tumor regression and histopathological examination revealed coagulative necrosis. The patient died of lung metastasis 2 years and 10 months after treatment. Case 2 was a 58-year-old-male with ascending colon cancer and liver metastasis, who received surgery, and chemotherapy with intraarterial 5-FU infusion was continued. Four months later, recurrence of liver metastasis with elevation of serum CEA was noted. The patient received PEI three times and CEA decreased. Re-operation of hepatectomy revealed complete necrosis at the site of PEI. The patient has been alive for 1 year and 6 months with a new recurrence in the liver and is receiving repeated PEI therapy. PEI and PAI seem to be useful for the treatment of unresectable liver metastasis.     

Malignant tracheoesophageal fistula in patients with esophageal cancer

BACKGROUND: Patients with esophageal cancer and a malignant tracheoesophageal fistula (TEF) have an extremely poor prognosis. Additionally, these patients often are denied treatment with radiation therapy because there is concern that these treatments may increase the size and associated problems of the TEF. METHODS: To determine the appropriate treatment (use of radiation therapy) for patients with esophageal cancer and malignant TEF, a review was performed of all such cases seen at the Mayo Clinic between 1971 and 1991. RESULTS: Between 1971 and 1991, 41 patients with malignant TEF arising as a result of esophageal cancer were seen at the Mayo Clinic in Rochester. Twenty-eight of these cancers were locally recurrent, and this group of patients had a uniformly poor outcome (median survival time, 1.4 months). Thirteen patients had a malignant TEF and had not received previous treatment for their esophageal cancer. The median survival length was 4 months for this group of patients. Of the 41 patients in this study, 10 received radiation therapy for their malignant TEF (30-66 Gy). The median survival length of this group of patients was 4.8 months. Six of these 10 patients died of metastatic disease (median survival length, 9 months), and there was no evidence of progression of the local tumor. Four of these 10 patients died of local progression of the malignancy (median survival length, 3 months). CONCLUSIONS: Radiation therapy did not increase the severity of the TEF. The authors conclude that radiation therapy can be administered safely in patients with TEF resulting from esophageal cancer. In some patients, radiation treatment may contribute to stabilization of the local tumor process (60% of patients treated with radiation therapy died of metastatic disease without local progression of tumor); however, all patients in this study eventually died of esophageal cancer.     

Neoadjuvant intraarterial chemotherapy for ten cases of inflammatory breast cancer by Seldinger's methods

The conventional methods (CM) of intraarterial (IA) chemotherapy for inflammatory breast cancer were catheterizations from superior epigastric and brachial artery under general anesthesia. Since 1997, we selected the Seldinger's methods (SM) for ten cases of the disease to control local effects and simplify the technique. Complications of the SM were slight, and side effects were equal to those with CM. The postoperative pathological findings of the SM showed the direct effects of chemotherapy to tumor cells (degenerative and necrotic changes) as compared with the embolism-like effects of CM. But the overall histological effects of chemotherapy by SM were almost equal to those for CM. The strong points of the SM were as follows: 1) More selective IA chemotherapy is available, 2) one can find the passage of the aim vessels and no trouble related to catheter, 3) general anesthesia is not necessary, and the techniques are simple, 4) the wounds are not remarkable. The disadvantages are as follows: 1) Patients must rest the day of IA chemotherapy, 2) in 20% of the procedures, one can not search the vessels, and 3) in 4 cases complications of stiffness of Mj or Mn pectral muscles were found. In future, we expect more effective results by dose escalation or combination chemotherapy.     

Continuous intra-hepatic-arterial infusion of low dose 5-fluorouracil for colorectal cancer patients with unresectable liver metastases

Five cases of colorectal cancer with unresectable liver metastases treated from April 1992 to April 1993 in Osaka National Hospital were summarized in this paper. A silicone catheter was placed in the hepatic artery through the gastroduodenal artery by operative procedure and connected to a subcutaneously implanted reservoir. 5-FU was administered ambulatorily using Baxter Infusor (multi day type) according to a regimen of 5-day continuous infusion and subsequent 2-day rest. The patients were 4 men and 1 woman, and from 51 to 65 years old (average: 62.4 y.o.). According to criteria for antitumor effectiveness by CT scan, one patient was judged CR, two were PR, and one was PD. One case could not be estimated because of catheter obstruction. The total efficacy rate was 75%. The serum CEA level was reduced in 3 patients. As for complication, obstruction of catheter, damage to reservoir and segmental necrosis of liver were observed in 3 patients. In conclusion, our ambulatory therapy for colorectal cancer patients with liver metastases was considered to have a high potential of not only effectiveness for cancer lesion but also the improvement of patients' quality of life.     

Secobarbital in humans discriminating triazolam under two-response and novel-response procedures

The percentage of long-term survivors after intensive chemotherapy and the outcome of MDS patients who achieve partial remission (PR) with intensive chemotherapy (IC) are not known. Between 1981 and 1996 we treated 99 patients with de novo MDS who had high-risk MDS or progression to AML, with IC. 41 (41%) achieved CR, 16 (16%) achieved partial remission (PR), 26 (26%) had failure, and 16 (16%) died in aplasia. Eight of the patients who achieved CR were autografted, three were allografted and the remaining cases received moderate consolidation chemotherapy. After IC, the 16 PR patients fulfilled the criteria for RA in 15 cases and CMML in one case. Median PR duration was 17 months, and three PR were > 3 years (39, 50+, 82+ months). Median actuarial survival of patients who achieved PR and CR was 18 months and 20 months from the onset of IC, respectively (difference not significant). Of the 71 patients treated before 1993, with sufficient follow-up, 10 (14%) had survived > 4 years (long-term survivors). Four of them were alive in first CR after 49+ to 110+ months and probably cured, two were alive in PR after 50+ and 82+ months and four had died after 49-78 months. Long-term survivors were characterized by a significantly higher incidence of RAEB-T at diagnosis, and with normal or favourable cytogenetic findings. In patients with RAEB-T at diagnosis included before 1993, 8/23 (35%) cases who had no unfavourable karyotype had survived > 4 years. Our findings suggest that MDS patients who achieve PR with IC, and not only those who achieve CR, can benefit from this type of treatment. The percentage of long-term survivors remains low, however, and is almost restricted to patients with RAEB-T at diagnosis and no unfavourable karyotype.     

Metabolism of quinine in children with global malnutrition

OBJECTIVE: To evaluate the frequency, predictive parameters and prognosis of urethral recurrence after cystoprostatectomy for urothelial bladder cancer. MATERIAL AND METHODS: From 1989 to 1994, 8 of a series of 185 patients (4.3%) treated by cystoprostatectomy for bladder carcinoma between 1988 and 1993 developed urethral recurrence revealed by urethral bleeding, with a follow-up of 6 to 36 months (m = 16). RESULTS: The initial bladder tumour was localized in 3 cases and multifocal in 5 cases. The posterior urethra was not involved in 5 cases, but presented lesions of CIS in 1 case and neoplastic infiltration also involving the prostate in 2 cases. These recurrences were treated by urethrectomy, as first-line treatment in 7 cases and after failure of endoscopic treatment in 1 case. A balanic recurrence required distal penectomy following insufficient urethral resection. The course was very rapidly unfavourable for 3 patients with generalized cancer and an intercurrent disease was fatal in 1 other case. With a follow-up of 12 to 44 months (m = 26), 4 patients are alive with no obvious signs of disease progression. CONCLUSION: The indications for prophylactic urethrectomy can be reserved to patients with positive urethral resection margins, provided all other cases are submitted to strict surveillance. In the context of a replacement bladder, it is essential to exclude neoplastic involvement of the posterior urethra or prostate, especially in patients previously treated by intravesical instillations.     

Neoadjuvant intra-arterial chemotherapy based on chemosensitivity tests for locally invasive bladder cancer

We investigated the clinical usefulness of individualization of chemotherapeutic regimen in neoadjuvant intra-arterial chemotherapy for locally invasive bladder cancer. Anticancer drugs were selected according to the results of an in vitro chemosensitivity test (collagen matrix assay or succinic dehydrogenase inhibition test). Nine patients with locally invasive bladder cancer received 1 to 4 courses of neoadjuvant intra-arterial chemotherapy, followed by radical cystectomy. Histopathological responses in the cystectomized specimens were grade 3 in 3 cases, grade 2 in 2, grade 1b in 2 and no response in 2. Pathologically, a complete response and downstaging were observed in 3 and 4 cases, respectively. Seven of the 9 patients were alive no evidence of disease with a mean follow-up period of 38.9 months, whereas 2 patients died of metastasis within 2 years. Six of the 7 patients who showed a complete response or down staging have been free of recurrence. These findings suggest that our chemotherapeutic strategy may improve the prognosis for locally invasive bladder cancer.     

Intra-arterial infusion chemotherapy for recurrent breast cancer via an implantable system--the second report

Intra-arterial infusion chemotherapy via an implantable port catheter has been applied in 16 patients with locally recurrent breast cancer. The regimen consisted of induction and subsequent maintenance: intra-arterial infusion of epirubicin (EPI). Non-responders were entered into the second-line regimen consisting of Methotrexate and 5-FU (MF). The results were as follows: 1) The response rate (CR+PR) of EPI to locoregional lesions was 50%, and the median duration of response was 5.7 months. 2) The response rate and the duration of response of MF were 25% and 3 months, respectively. 3) Patients with ER-rith, no previous therapy and a long disease-free interval tended to have a high rate of response to intra-arterial infusion therapy. 4) Improvements of QOL, such as intractable pain, infection and severe lymphedema were recognized in 68.6% of the cases. In more than half of the cases, these treatments were carried out in an outpatient clinic. 5) Leucopenia and catheter or portal problems were encountered in 68.6% and 25.0%, respectively. We conclude that intra-arterial infusion chemotherapy via implantable system is a promising modality with regard to therapeutic effect and improvement of quality of life.     

Phase II study of continuous infusion carmustine and cisplatin followed by cranial irradiation in adults with newly diagnosed high-grade astrocytoma

PURPOSE: To evaluate the activity and toxicity of carmustine (BCNU) and cisplatin administered as a 72-hour continuous intravenous infusion before radiation in adults with newly diagnosed high-grade astrocytomas. PATIENTS AND METHODS: Fifty-two patients with a Karnofsky performance status greater than 60 and no prior antineoplastic therapy entered this protocol. The median age of the patients was 55 years. Eighty-eight percent had glioblastoma multiforme and 12% had anaplastic astrocytomas. BCNU (40 mg/m2/d) and cisplatin (40 mg/m2/d) were administered concurrently as a 72-hour infusion every 3 to 4 weeks. Radiation was begun 4 weeks after the third cycle of chemotherapy or earlier for progressive disease. Responses required a > or = 50% reduction in contrast-enhancing volume. RESULTS: Forty patients (77%) completed three chemotherapy infusions, five (10%) received two infusions, and seven (13%) received only one. Fifty-one patients completed radiation. Seventeen (42%) patients with measurable disease had a partial response (PR) to chemotherapy, 23 (53%) had stable disease (SD), and two (4%) had progressive disease (PD) on chemotherapy. The median survival time for all patients was 13 months. Survival rates at 1, 2, 3, and 5 years were 62%, 19%, 12%, and 5%, respectively. Grade III to IV leukopenia occurred in 32% of patients; 63% received platelet transfusions and 58% required RBCs. Neutropenic fevers were rare and no intracranial hemorrhages or treatment-related deaths were noted. Nausea, vomiting, peripheral neuropathy, hearing loss, and thromboembolic events were relatively common. CONCLUSION: This chemotherapy regimen appears to have significant activity and may prolong survival in adults with newly diagnosed high-grade astrocytoma.     

Alcohol-related words are distracting to both alcohol abusers and non-abusers in the Stroop colour-naming task

A combination chemotherapy with continuous infusion of cisplatin (5 mg/body, day 1-5) and UFT (400-600 mg/body, day 1-5) was administered to thirteen patients for advanced non-small cell lung cancer. Myelosuppression and other toxicity were mild, and the quality of life of the patients was good. The response rate of thirteen patients was 23% (CR 0, PR 3). It was considered that chemotherapy using cisplatin (5 mg/body, day 1-5) and UFT (400-600 mg/body, day 1-5) was well tolerated and effective for the treatment of non-small cell lung cancer.     

Prognostic factors in surgically treated small cell cervical carcinoma followed by adjuvant chemotherapy

BACKGROUND: Small cell carcinoma of the uterine cervix is an uncommon tumor associated with high mortality even among patients with early stage disease. The role of adjuvant chemotherapy after surgery has been suggested by regimens used for small cell lung carcinoma. During the years 1980-1997, 19 cases in which various adjuvant chemotherapies were given after hysterectomy were reported in the literature published in English. METHODS: Adjuvant chemotherapy was administered consecutively to 23 patients with Stage Ib-II small cell cervical carcinoma who had been primarily treated with radical hysterectomy and had adequate bone marrow, renal, and hepatic functions. A combination of vincristine, doxorubicin, and cyclophosphamide alternating with cisplatin and etoposide (VAC/PE) was administered to 14 patients during the years 1988-1996 according to a prospective study protocol. A combination of cisplatin, vinblastine, and bleomycin (PVB) was administered to 8 patients, and another regimen was administered to 1 patient during the years 1984-1988. Prognostic factors were evaluated by analyzing both the data on these 23 patients and the pooled data on the cases retrieved from the literature and our own files. RESULTS: Ten of the 14 patients who received VAC/PE had no evidence of disease during a median follow-up of 41 months, whereas 3 of the 9 who received PVB or another regimen survived. Of the 10 patients who died of their disease, all died of distant metastasis within 10 months after recurrence. Meta-analysis of the pooled data showed that 68% of patients who received regimens containing VAC or PE survived, whereas 33% of patients who received regimens not containing VAC/PE survived (P = 0.0078, log rank test). Seventy percent of patients with no lymph node metastasis at hysterectomy and 35% with lymph node metastasis survived (P = 0.05). All patients who died of disease had extrapelvic metastasis. CONCLUSIONS: Chemotherapies containing VAC or PE are favorable regimens for patients with early stage small cell cervical carcinoma after radical hysterectomy.
