Safety and efficacy of ECT in patients with head injury: a case series

BACKGROUND: The role of postoperative radiotherapy and adjuvant chemotherapy in the treatment of synovial sarcoma remains to be determined. PROCEDURE: Twenty-five children were treated during a 23-year period with a multimodality approach. All of them had resection of the primary tumor (three amputations), followed by surgical retreatment in eight. Postoperative radiotherapy was delivered to 16 patients and adjuvant chemotherapy was given to 22. RESULTS: At the time of the report, 19 patients were alive and without evidence of disease. Six developed distant metastases (one associated with local recurrence); five of them died of their disease and one was alive in complete remission at 4 years from relapse. With a median follow-up of 9 years (range 2-23), the survival and the event-free survival at 5 years were 80% (SE 8.2) and 74% (SE 9.2), respectively. All relapsing patients had been classified as T2B. CONCLUSIONS: Multimodality treatment yielded satisfying survival results using limb-preserving surgery in most cases. Tumor size > 5 cm and invasiveness, which defined stage T2B, were the most important predictors of poor outcome. Evaluation of the role of adjuvant chemotherapy and radiotherapy awaits prospective studies, even if T2B patients, as well as children having nonradical surgery, seem worth managing by adjuvant treatments.

Combined irradiation and chemotherapy using ifosfamide, cisplatin, and etoposide for children with medulloblastoma/posterior fossa primitive neuroectodermal tumor--results of a pilot study

Ten children with newly diagnosed medulloblastoma/primitive neuroectodermal tumor of the posterior fossa were treated with total surgical resection, radiation therapy, and ICE chemotherapy regimen with ifosfamide (900 mg/m2, days 1-5), cisplatin (20 mg/m2, days 1-5), and etoposide (60 mg/m2, days 1-5) every 4 weeks for eight cycles. Four children under 2 years old were at first treated with eight cycles of ICE chemotherapy, and then irradiated. The ICE regimen was well tolerated by all children, with no irreversible adverse effects. However, dose reductions during the eight cycles were inevitable mainly due to myelosuppression. Complete remissions were achieved in eight of 10 patients at 1 month after completion of the treatment. One child showed recurrence 21 months after complete remission. The disease-free survival rate was 70% with a mean observation period of 24 months after surgery. The ICE regimen is a useful treatment modality for children with medulloblastoma. Further study is warranted to clarify long-term outcome in a number of patients.     

Surgery in the management of small cell lung cancer

OBJECTIVE: We analyzed our experience in the period January 1975-December 1995 aiming to confirm the role of surgery in the multimodality treatment of small cell lung cancer (SCLC). METHODS: 127 patients (5.28% of the overall lung resections for carcinoma) underwent surgery for SCLC. The median age was 60 years (range 34-73). In 87 patients (68.5%) a pre-operative tissue diagnosis was effected and those patients underwent a complete staging procedure. Fifteen patients received up to six complete courses of neoadjuvant and adjuvant chemotherapy. The surgical procedures included: 50 pneumonectomies, 71 lobectomies and six wedge resections. Two patients experienced a local recurrence and a completion pneumonectomy was performed. RESULTS: The median follow-up is 66 months (range 6-214). The 5-year actuarial survival rate is 22.6% (median 18 months). Twenty-three patients are still alive, 21 of them being disease-free. Considering the most conspicuous group of patients (n = 92) treated by surgery and adjuvant chemotherapy, the survival data were 47.2, 14.8 and 14.4% for Stage I, II and III, respectively (P = 0.001). NO patients had a significantly better survival than N1 and N2 patients (P = 0.035). CONCLUSIONS: Surgery and adjuvant chemotherapy might represent an effective form of treatment of limited SCLC without lymph-node involvement. The role of surgery is yet to be verified as regards N1 and N2 status, where even neoadjuvant chemotherapy has not achieved the hoped-for results (no patient reaching a 2-year survival).     

Combined modality therapy in previously untreated patients with advanced Hodgkin's disease: A 24-year follow-up study

PURPOSE: To describe the long-term results of treatment with chemotherapy plus adjuvant low-dose, involved-field radiation therapy (CMT) in patients with advanced Hodgkin's disease. Data on disease-free and failure-free survival, second malignancies, and the results of salvage therapy are presented. PATIENTS AND METHODS: From 1969 to 1989, CMT was administered to 186 patients with previously untreated stage IIB, III, and IV Hodgkin's disease. Chemotherapy included MVVPP (47%), MOPP (25%), MOPP/ABVD (26%) and ABVD (2%). After 6 months of chemotherapy, patients received radiation to all involved sites with the exception of the bone marrow. RESULTS: The failure-free survival for all patients was 63% at 5 years, 56% at 10 years, and 40% at 23.5 years, respectively. Significantly worse results were observed in patients older than 40 years and those with stage IV disease. The overall survival of 45 patients after recurrence was 39% at 10 years, but was only 21% if the initial complete remission lasted less than 1 year. Thus far, 21 of 165 patients (12.7%) who achieved complete remission have developed a second malignancy, and 16 have died. CONCLUSIONS: In comparison with comparable chemotherapy programs, chemotherapy plus radiation therapy may improve disease-free survival; however, the results of treatment in patients older than age 40 or with stage IV disease are still poor. Although patients with initial remissions lasting longer than 1 year can have durable second remissions, the long-term disease-free survival is poor and in the current series the majority of failures were due to recurrent Hodgkin's disease.     

Treatment of non-metastatic rhabdomyosarcomas in childhood and adolescence. Results of the second study of the International Society of Paediatric Oncology: MMT84

The second International Society of Paediatric Oncology (SIOP) study for rhabdomyosarcoma (MMT84) had several goals. The two principal aims were: (1) to improve the survival of children with rhabdomyosarcoma; and (2) to reduce the late effects from therapy by restricting the indications for surgery and/or radiotherapy after good response to initial chemotherapy. A further aim was to investigate the role of high-dose chemotherapy in young patients with parameningeal primary tumours. 186 previously untreated eligible patients entered the study. Patients with completely resected primary tumour received three courses of IVA (ifosfamide, vincristine and actinomycin D). Patients with incompletely resected tumour received six to 10 courses of IVA according to stage. Patients achieving complete remission with chemotherapy alone did not usually receive radiotherapy or undergo extensive surgery, but patients remaining in partial remission received local therapy with surgery and/or radiotherapy. Only patients over 5 years of age with parameningeal disease and patients over 12 years with tumours at any site were given systematic irradiation. Complete remission was achieved in 91% (170/186) of all patients. With a median follow-up of 8 years, the 5-year overall survival was 68% (+/- 3% standard error of the mean (SEM) and the 5-year event-free survival 53% (+/- 4% SEM). These results show an improvement over previous SIOP study (RMS75) in which survival was 52% and event-free survival was 47%. Among the 54 patients who exhibited isolated local relapse, 35% (19/54) survived in further remission longer than 2 years after retreatment, including local therapy (surgery +/- radiotherapy). Analysis of the overall burden of therapy received by all surviving children (including primary treatment and treatment for relapse if required) showed that 24% (28/116) were treated by limited surgery followed by three courses of IVA, 29% (34/116) were treated by chemotherapy alone (after initial biopsy) and 13% (15/116) received chemotherapy plus conservative local treatment (limited surgery or radiotherapy for residual disease). Only 34% (39/116) received intensive local therapy defined as radical wide field radiotherapy or radical surgery or both. Compared with the results obtained in the previous SIOP study, treatment in MMT84 was based on response to initial chemotherapy and, despite an overall reduction of the use of local therapy, significantly improved survival for patients with non-metastatic disease. This trial, also for the first time, provides evidence that retreatment after local relapse can achieve long-term second remissions.     

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).     

Haemorrhagic hydrops of the gallbladder

Primary carcinoma of the fallopian tube is uncommon; optimal primary treatment is still not well defined, and little information is available about the efficacy of cisplatin-based combination chemotherapy. Thirty-eight patients with fallopian tube carcinoma were treated with cyclophosphamide (500 mg/m2), Adriamycin (50 mg/m2), and cisplatin (50 mg/m2) (CAP). Thirty-two patients received the combination chemotherapy as first-line treatment after cytoreductive surgery, whereas six subjects were treated for recurrent disease. The patients received a median of six cycles of therapy (range, four to nine). At the initiation of chemotherapy, 24 patients had measurable lesions. In this group of patients, 15 had a clinical complete response (CR), four had a partial response (PR), three had stable disease (SD), and two had progressive disease (PD) after chemotherapy. The overall clinical response rate (CR + PR) was 80%. Ten of the 14 CR patients who were submitted to second-look operation (SLO) were found free of disease, in pathologic complete response (pCR). Three pCR patients relapsed, and two of them died despite second-line treatment. Nine patients achieving PR, SD, and PD after first-line chemotherapy were further treated (five with chemotherapy, two with radiotherapy, two with progesteron), but none responded to second-line treatment and all died (median survival, 9 months). Fourteen patients without gross residual disease after cytoreductive surgery had no measurable lesions and were not evaluable for response. Seven of them had negative SLO and remain disease free. Three patients (two stage III and one stage II) who refused SLO relapsed 14, 16, and 26 months after completion of chemotherapy. The median survival for the entire group was 38 months, and the 5-year survival rate was 35%. The toxicity of the regimen was moderate. The CAP regimen appears to be active in primary fallopian tube carcinoma and yields response rates comparable to those reported for epithelial ovarian cancer.     

Palliative chemotherapy with CMF after the same adjuvant regimen for breast cancer. The Breast Cancer Study Group

BACKGROUND: The results of palliative chemotherapy with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) in patients with advanced breast cancer who received adjuvant therapy with the same regimen were investigated. RESULTS: Of 47 patients, 14 (30%) achieved an objective remission (median duration 9.5, range 5-21 months) and 8 (17%) stabilisation of disease (median duration 6, range 3-17 months). Objective remissions were observed in premenopausal as well as in postmenopausal women, in patients with all categories of dominant localisation of disease and regardless of the oestradiol receptor status of the primary tumour or eventual previous endocrine therapy. One of 4 and 13 of 43 patients who started palliative chemotherapy within or later than 12 months after the last adjuvant course obtained an objective remission. The median survival time from start of therapy of all treated patients was 12 (range 1-40) months. Patients with an objective remission or stable disease and patients with progressive disease had a median survival time of 20 (range 6-40) and 6 (range 1-35) months respectively (p < 0.0001). CONCLUSIONS: Palliative treatment with CMF should not be rejected for patients who have relapsed after adjuvant chemotherapy with the same modality.     

Adjuvant combination chemotherapy (AMF) following radical resection of carcinoma of the pancreas and papilla of Vater--results of a controlled, prospective, randomised multicentre study

Between 1984 and 1987, 61 radically resected patients with carcinoma of the pancreas (n = 47) or the papilla of Vater (n = 14) were randomised either into postoperative adjuvant combination chemotherapy (AMF); 5-fluorouracil 500 mg/m2, doxorubicin 40 mg/m2, mitomycin C 6 mg/m2 (n = 30) once every 3 weeks for six cycles, or into a control group (no adjuvant chemotherapy) (n = 31). The median survival in the treatment group was 23 months compared with 11 months (P = 0.02, median test) in the control group, dependent on a survival benefit in the treatment group during the initial 2 years (P = 0.04 generalised Wilcoxon). The long-term prognosis was the same with an identical survival after 2 years (P = 0.10, power = 0.83). The observed 1, 2, 3 and 5-year survivals in the treatment group were 70, 43, 27 and 4% compared with 45, 32, 30 and 8 in the control group. 1 patient succumbed to sepsis probably attributable to chemotherapy. Cardiotoxicity and nephrotoxicity were recorded in 2 patients. These results suggest that adjuvant chemotherapy does postpone the incidence of recurrence in the first 2 years following radical surgery but increased cure rate was not observed.     

Adjuvant chemotherapy for primary cardiac sarcomas: the IGR experience

The effect of additional treatments after surgery in patients with primary cardiac sarcoma (PCS) remains unknown. The present study aims to evaluate the benefit of chemotherapy in patients with non-metastatic cardiac sarcomas after optimal resection. Between October 1979 and December 1995, 15 patients with a median age of 45 (range 16-66) and a resected primary cardiac sarcoma [angiosarcoma (six), malignant fibrous histiocytoma (three), leiomyosarcoma (two), rhabdomyosarcoma (two), liposarcoma (one) and synoviosarcoma (one)] received a doxorubicin-containing regimen within 6 weeks of surgery. Adjuvant chemotherapy combinations included cyclophosphamide, vincristine and dacarbazine in four patients; ifosfamide in nine; methotrexate and vincristine in one; and doxorubicin alone in one patient. At present, 13 patients have relapsed (five during therapy), with a median time to progression of 10 months. Twelve patients developed local relapse, in four cases without metastatic disease. Two patients remain in complete remission 27 and 25 months after surgery. The median time to progression was shorter in patients presenting a cardiac angiosarcoma than other histological types (3 vs 14 months, P < 0.01). Twelve patients have died, with a median overall survival of 12 months. The 2-year survival rate is 26%. Survival was significantly longer for patients with completely resected tumours (22 vs 7 months; P = 0.02) and those who did not have angiosarcoma (18 vs 7 months; P = 0.04). In conclusion, post-operative conventional doxorubicin-based chemotherapy failed to modify the natural history of patients with resected cardiac sarcomas. Locoregional failure remains the main problem even after histologically complete resection. New approaches must be tested in patients with primary cardiac sarcoma.     

A randomized controlled trial of filgrastim during remission induction and consolidation chemotherapy for adults with acute lymphoblastic leukemia: CALGB study 9111

Recombinant human granulocyte colony-stimulating factor (G-CSF; filgrastim) shortens the time to neutrophil recovery after intensive chemotherapy, but its role in the treatment of adults with acute lymphoblastic leukemia (ALL) is uncertain. We randomly assigned 198 adults with untreated ALL (median age, 35 years; range, 16 to 83) to receive either placebo or G-CSF (5 microgram/kg/d) subcutaneously, beginning 4 days after starting intensive remission induction chemotherapy and continuing until the neutrophil count was >/=1, 000/microL for 2 days. The study assignment was unblinded as individual patients achieved a complete remission (CR). Patients initially assigned to G-CSF then continued to receive G-CSF through 2 monthly courses of consolidation therapy. Patients assigned to placebo received no further study drug. The median time to recover neutrophils >/=1,000/microL during the remission induction course was 16 days (interquartile range [IQR], 15 to 18 days) for the patients assigned to receive G-CSF and 22 days (IQR, 19 to 29 days) for the patients assigned to placebo (P < .001). Patients in the G-CSF group had significantly shorter durations of neutropenia (<1, 000/microL) and thrombocytopenia (<50,000/microL) and fewer days in the hospital (median, 22 days v 28 days; P = .02) compared with patients receiving placebo. The patients assigned to receive G-CSF had a higher CR rate and fewer deaths during remission induction than did those receiving placebo (P = .04 by the chi-square test for trend). During Courses IIA and IIB of consolidation treatment, patients in the G-CSF group had significantly more rapid recovery of neutrophils >/=1,000/microL than did the control group by approximately 6 to 9 days. However, the patients in the G-CSF group did not complete the planned first 3 months of chemotherapy any more rapidly than did the patients in the placebo group. Overall toxicity was not lessened by the use of G-CSF. After a median follow-up of 4. 7 years, there were no significant differences in either the disease-free survival (P = .53) or the overall survival (P = .25) for the patients assigned to G-CSF (medians, 2.3 years and 2.4 years, respectively) compared with those assigned to placebo (medians, 1.7 and 1.8 years, respectively). Adults who received intensive chemotherapy for ALL benefited from G-CSF treatment, but its use did not markedly affect the ultimate outcome.     

Adjuvant portal-vein infusion of fluorouracil and heparin in colorectal cancer: a randomised trial. European Organisation for Research and Treatment of Cancer Gastrointestinal Tract Cancer Cooperative Group, the Gruppo Interdisciplinare Valutazione Interventi in Oncologia, and the Japanese Foundation for Cancer Research

BACKGROUND: There is conflicting evidence on the efficacy of regional adjuvant chemotherapy, via portal-vein infusion (PVI), after resection of colorectal cancer. We undertook a randomised controlled multicentre trial to investigate the efficacy of PVI (500 mg/m2 fluorouracil plus 5000 IU heparin daily for 7 days). METHODS: 1235 of about 1500 potentially eligible patients were randomly assigned surgery plus PVI or surgery alone (control). The patients were followed up for a median of 63 months, with yearly screening for recurrent disease. The primary endpoint was survival; analyses were by intention to treat. FINDINGS: 619 patients in the control group and 616 in the PVI group met eligibility criteria. 164 (26%) control-group patients and 173 (28%) PVI-group patients died. 5-year survival did not differ significantly between the groups (73 vs 72%; 95% Cl for difference -6 to 4). The control and PVI groups were also similar in terms of disease-free survival at 5 years (67 vs 65%) and the number of patients with liver metastases (79 vs 77%). INTERPRETATION: PVI of fluorouracil, at a dose of 500 mg/m2 for 7 days, cannot be recommended as the sole adjuvant treatment for high-risk colorectal cancer after complete surgical excision. However, these results cannot eliminate a small benefit when PVI is used at a higher dosage or in combination with mitomycin.     

The lymphoid system and its role in maintaining immunocompetence

More than half of the children and adolescents with malignant brain tumors will relapse following initial therapy. Irrespective of the therapeutic modalities the prognosis of patients with recurrent or metastatic brain tumors is still poor. New strategies such as high dose chemotherapy (HDCT) with autologous blood stem cell transplantation (ABSCT) offer the possibility to improve the longterm prognosis of these patients. Following conventional chemotherapy with carboplatin/etoposide and after achieving complete or partial remission (CR or PR) 10 patients aged from 3.2 to 25.5 years (median, 10.3 years) with refractory or recurrent malignant brain tumors (anaplastic astrocytoma/glioblastoma, n = 2; medulloblastoma/PNET, n = 6; ependymoma, n = 1; plexus carcinoma, n = 1) received in a pilot study one course of HDCT with ABSCT. The consolidation regimen consisted of thiotepa (400-600mg/m2/d, i.v. 6 h, d-9), carboplatin and etoposide (500mg/m2/d, CVI 24h, d-8 to d-5, respectively) and was followed by the retransfusion of autologous blood stem cells on day 0. Before starting HDCT 6 patients showed CR and 4 patients had PR or stable disease (SD). Following the HDCT 3 of the 4 patients with residual tumor had CR or PR. 6 patients have remained in continuous CR or SD 8 to 41 months (median 17.2 months) after the HDCT. 2 patients relapsed 8.5 and 9.5 months after HDCT and died from progressive disease. Two patients died therapy-related from systemic aspergillosis and were not evaluable for response. Hematological recovery with an absolute neutrophile count of > 0.5 x 10(9)/l and a platelet count of > 30 x 10(9)/l was reached on days +11 (median; range, +9 to +14) and +16 (median; range, +6 to +47), respectively. The main nonhematological toxic effects were infections, severe mucositis, and hyperbilirubinemia. Although the long-term efficacy of HDCT with ABSCT is still not evaluable and the toxicity of this regimen is high, a multicenter phase II trial seems to be justified in view of the poor prognosis of recurrent or refractory brain tumors in children and adolescents.     

Vinorelbine treatment of recurrent salivary gland carcinomas

Twenty patients (13 males, 7 females, median age 61 years, range 27-74) with recurrent adenocarcinoma-like tumors of major (10 patients) and minor (10 patients) salivary gland origin (13 adenoid cystic carcinoma, 5 adenocarcinoma, 1 malignant mixed tumor, 1 undifferentiated carcinoma) were treated with vinorelbine at the dose of 30 mg/m2 i.v. weekly. Sixteen patients had been previously treated with surgery + radiation, 3 with surgery + radiotherapy + Novantrone and 1 with radiotherapy alone. Nine patients had local recurrence, 2 local relapse + metastasis and 9 metastasis alone. Site of metastases are: lung (7), bone (1), lung + bone (2), lung + bone + lymph-node + skin (1). Overall 174 courses were given (median 9, range 6-19). Responses were: PR in 4 patients (20%) with a median duration of 6 months (3-9), 9 NC (45%) with a median duration of 3.5 months and 7 PD (35%). The median survival time was 10 months for PR/NC patients, 4 months for non-responders. Median overall survival was 7 months. Vinorelbine has a moderate activity in these very advanced cases.     

Generation of superoxide anion and induction of superoxide dismutase and peroxidase in bean leaves infected with pathogenic fungi

PURPOSE: The purpose of this study was to review management strategies with respect to systemic therapy, radiation therapy treatment techniques, and patient outcome (local regional control, distant metastases, and overall survival) in patients undergoing conservative surgery and radiation therapy (CS + RT) who had four or more lymph nodes involved at the time of original diagnosis. METHODS AND MATERIALS: Of 1040 patients undergoing CS + RT at our institution prior to December 1989, 579 patients underwent axillary lymph node dissection. Of those patients undergoing axillary lymph node dissection, 167 had positive nodes and 51 of these patients had four or more positive lymph nodes involved and serve as the patient population base for this study. All patients received radiation therapy to the intact breast using tangential fields with subsequent electron beam boost to the tumor bed to a total median dose of 64 Gy. The majority of patients received regional nodal irradiation as follows: 40 patients received RT to the supraclavicular region without axilla to a median dose of 46 Gy, 10 patients received radiation to the supraclavicular region and axilla to a median dose of 46 Gy. Thirty of the 51 patients received a separate internal mammary port with a mixed beam of photons and electrons. One patient received radiation to the tangents alone without regional nodal irradiation. Adjuvant systemic therapy was used in 49 of the 51 patients (96%) with 27 patients receiving chemotherapy alone, 14 patients receiving cytotoxic chemotherapy and tamoxifen, and 8 patients receiving tamoxifen alone. RESULTS: As of December 1994, with a minimum evaluable follow-up of 5 years and a median follow-up of 9.29 years, there have been 18 distant relapses, 2 nodal relapses, and 5 breast relapses. Actuarial statistics reveal a 10-year distant metastases-free rate of 65%, 10-year nodal recurrence-free rate of 96%, and a 10-year breast recurrence-free rate of 82%. All five patients who sustained a breast relapse were successfully salvaged with mastectomy. Both patients with nodal relapses (one supraclavicular and one axillary/supraclavicular) failed within the irradiated volume. Of the 40 patients treated to the supraclavicular fossa (omitting complete axillary radiation), none failed in the dissected axilla. With a median follow-up of nearly 10 years, 29 of the 51 patients (57%) remain alive without evidence of disease, 15 (29%) have died with disease, 2 (4%) remain alive with disease, and 5 (10%) have died without evidence of disease. Overall actuarial 10-year survival for these 51 patients is 58%. CONCLUSIONS: We conclude that in patients found to have four or more positive lymph nodes at the time of axillary lymph node dissection, conservative surgery followed by radiation therapy to the intact breast with appropriate adjuvant systemic therapy results in a reasonable long-term survival with a high rate of local regional control. Omission of axillary radiation in this subset of patients appears appropriate because there were no axillary failures among the 41 dissected but unirradiated axillae.     

A Tourette-like syndrome following cardiopulmonary bypass and hypothermia: MRI volumetric measurements

OBJECTIVES: To review the outcome of men with Stage I nonseminomatous germ cell tumors managed with a policy of active surveillance following orchiectomy. METHODS: The clinical records of all men with Stage I nonseminomatous germ cell tumors seen at Royal Prince Alfred Hospital, Australia between 1982 and 1995 were reviewed. Data were obtained concerning the histologic type of tumor, levels of serum tumor markers, relapse and subsequent treatment, and survival. RESULTS: Seventy-seven patients were entered into the active surveillance protocol between 1982 and 1995. With a minimum follow-up of 2 years, 27 (35%) have relapsed, with a median time to relapse of 5 months. Two late relapses occurred at 37 and 57 months after diagnosis. Relapses occurred most commonly in the retroperitoneal lymph nodes, with the lungs the second most common site. Following treatment with chemotherapy and surgery, all patients achieved complete remission, with 1 patient subsequently relapsing and ultimately dying of progressive tumor. One other patient died of acute myeloid leukemia, thought to be secondary to chemotherapy. Overall, 75 patients (97%) remain alive and free of disease. CONCLUSIONS: Active surveillance is a safe and effective approach to the management of Stage I nonseminomatous germ cell tumors. Although most relapses occur within the first 2 years, late relapses may occur.     

Dose and dose intensity as determinants of outcome in the adjuvant treatment of breast cancer. The Cancer and Leukemia Group B

BACKGROUND: Both total dose and dose intensity of adjuvant chemotherapy are postulated to be important variables in the outcome for patients with operable breast cancer. The Cancer and Leukemia Group B study 8541 examined the effects of adjuvant treatment using conventional-range dose and dose intensity in female patients with stage II (axillary lymph node-positive) breast cancer. METHODS: Within 6 weeks of surgery (radical mastectomy, modified radical mastectomy, or lumpectomy), 1550 patients with unilateral breast cancer were randomly assigned to one of three treatment arms: high-, moderate-, or low-dose intensity. The patients received cyclophosphamide, doxorubicin, and 5-fluorouracil on day 1 of each chemotherapy cycle, with 5-fluorouracil administration repeated on day 8. The high-dose arm had twice the dose intensity and twice the drug dose as the low-dose arm. The moderate-dose arm had two thirds the dose intensity as the high-dose arm but the same total drug dose. Disease-free survival and overall survival were primary end points of the study. RESULTS: At a median follow-up of 9 years, disease-free survival and overall survival for patients on the moderate- and high-dose arms are superior to the corresponding survival measures for patients on the low-dose arm (two-sided P<.0001 and two-sided P = .004, respectively), with no difference in disease-free or overall survival between the moderate- and the high-dose arms. At 5 years, overall survival (average +/- standard error) is 79% +/- 2% for patients on the high-dose arm, 77% +/- 2% for the patients on the moderate-dose arm, and 72% +/- 2% for patients on the low-dose arm; disease-free survival is 66% +/- 2%, 61% +/- 2%, and 56% +/- 2%, respectively. CONCLUSION: Within the conventional dose range for this chemotherapy regimen, a higher dose is associated with better disease-free survival and overall survival.     

Acute promyelocytic leukemia: all-trans retinoic acid (ATRA) along with chemotherapy is superior to ATRA alone

This study was conducted to compare the results of treatment of acute promyelocytic leukemia (APL) with all-trans retinoic acid alone (ATRA) or a combination therapy of ATRA followed by chemotherapy. Forty-three patients treated between February 1992 and February 1996 were included in this study. Eighteen patients were treated with ATRA alone and 25 patients were treated with ATRA followed by chemotherapy. The cytogenetic analysis was done in 41 patients at presentation, following treatment, and at follow-up. A complete response (CR) was achieved in 13 (72%) patients on ATRA and 19 (76%) on ATRA followed by chemotherapy. Eleven of 13 patients with response to ATRA alone relapsed with median survival of eight months (range, 1 to 28). One patient died of hepatitis in CR and one patient is alive 2 years after diagnosis. In the combination therapy arm, 10 patients are in CR with a median follow-up of 22 months (range, 6 to 56 months). After achieving a CR, four patients died due to infections during chemotherapy therapy, and only 5 of 19 patients have relapsed. Major cytogenetic response was seen in 8 of the 10 patients in whom cytogenetic data was available after treatment with ATRA at the time of remission. Similarly, 13 of 15 for whom data was available showed a major cytogenetic response after treatment with ATRA plus chemotherapy. Prior to relapse, 80% of the patients had an increase in the percentage of t(15;17) cells in the marrow. Patients with a complete hematological response but no cytogenetic response relapsed within six months. Ten patients died prior to response evaluation. Two patients who received ATRA died of retinoic acid syndrome, one of pneumonia, and one of intracranial hemorrhage. Of the six patients on ATRA and chemotherapy, four died of retinoic acid syndrome (RAS), one of intracranial hemorrhage, and one of left ventricular failure. Only one patient is alive at 24 months following treatment with ATRA alone. The relapse-free survival is 42% at four years for patients treated with ATRA followed by chemotherapy. This trial is a historical comparison of ATRA alone and ATRA with subsequent combination chemotherapy. Nonetheless, the trial shows a significant improvement in the event free survival of patients receiving chemotherapy as consolidation following ATRA.     

A study of intermittent alternating drug program reinduction therapy on the frequency and duration of response in adult acute leukemia

Of 41 adults with a diagnosis of acute leukemia that were randomized for induction therapy in combination with methotrexate, 6-MP, vincristine and prednisone (POMP) versus a combination of cytosine arabinoside, cytoxan, vincristine and prednisone (COAP), 23 (56%) patients achieved a complete remission. During remission, patients received consolidation therapy with the three courses of remission induction regimen that they had not received initially. They then received daunomycin (three courses) and L-asparaginase and were then maintained for two years with their induction therapy. The median duration of survival for all patients was 40 weeks; the median duration of survival of those patients that responded to chemotherapy was 80 weeks. There was no significant difference between the two induction regimens with regard to complete remission more than four and one half years from diagnosis and two and one half years from discontinuation of all therapy.
