PURPOSE To investigate the efficacy of concurrent hyperfractionated radiation therapy (HFX RT) and low-dose daily chemotherapy (CHT) in stage III non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Between January 1990 and December 1991, 131 patients with histologically or cytologically confirmed stage III NSCLC, Karnofsky performance status (KPS) > or = 50, and no previous therapy were randomly treated as follows: group I, HFX RT with 1.2 Gy twice daily to a total dose of 69.6 Gy (n = 66); and group II, same HFX RT with CHT consisting of 50 mg of carboplatin (CBDCA) and 50 mg of etoposide (VP-16) given on each RT day (n = 65). RESULTS Group II patients had a significantly longer survival time than group I patients, with a median survival of 22 versus 14 months and 4-year survival rates of 23% versus 9% (P = .021). The median time to local recurrence and 4-year local recurrence-free survival rate were also significantly higher in group II than in group I (25 v 20 months and 42% v 19% respectively, P = .015). In contrast, the distant metastasis-free survival rate did not significantly differ in the two groups (P = .33). The two groups showed similar incidence of acute and late high-grade toxicity (P = .44 and .75, respectively). No treatment-related toxicity was observed. CONCLUSION The combination of HFX RT and low-dose daily CBDCA plus VP-16 was tolerable and improved the survival of patients with stage III NSCLC as a result of improved local control.

PURPOSE The efficacy and toxicity of high-dose carboplatin, etoposide, and cyclophosphamide with autologous bone marrow transplantation (AuBMT) was investigated in a prospective trial for patients with cisplatin-refractory germ cell tumor (GCT). Prognostic factors for survival and treatment-related toxicity were identified. PATIENTS AND METHODS Fifty-eight patients with refractory GCT were treated with high-dose carboplatin, etoposide, and cyclophosphamide plus AuBMT. Prognostic factors for toxicity and survival were examined in multivariate analyses. RESULTS Twenty-three patients (40%) achieved a complete response and 12 (21%) are alive and free of disease at a median follow-up time of 28 months. Myelosuppression was severe and there were seven (12%) treatment-related deaths. Independently predictive factors that resulted in faster blood count recovery were the use of granulocyte colony-stimulating factor (G-CSF) for the number of days to neutrophil count recovery (P = .013) and prior treatment with cisplatin limited to six cycles or less for the number of days to platelet count recovery (P = .0012). Both were predictive for the number of days of hospitalization (P = .04 and .03, respectively). The two independently predictive variables for survival were pretreatment level of HCG; human chorionic gonadotrophin (HCG; < or = 100 times the upper limit of normal [xnl] v > 100 xnl, P = .02) and the presence of retroperitoneal metastases (yes or no, P = .04). Patients grouped by HCG < or = 100 xnl with retroperitoneal metastases, HCG < or = 100 xnl without retroperitoneal metastases, and all patients with HCG more than 100 xnl had median survival times of 14, 11, and 3 months, respectively (P = .04). CONCLUSION High-dose carboplatin, etoposide, and cyclophosphamide is an effective therapy for patients with refractory GCT, and results in a complete response proportion of 40% and a 2-year survival rate of 31% at a median follow-up time of 28 months. This was accomplished in a group of patients with a dismal prognosis to conventional-dose therapy.

PURPOSE To evaluate irinotecan (CPT-11; Yakult Honsha, Tokyo, Japan) in patients with metastatic colorectal carcinoma that had recurred or progressed following fluorouracil (5-FU)-based therapy. PATIENTS AND METHODS Patients were treated with irinotecan 125 to 150 mg/m2 intravenously (IV) every week for 4 weeks, followed by a 2-week rest. Forty-eight patients were entered onto the study and all were assessable for toxicity. Forty-three patients completed one full course of therapy and were assessable for response. RESULTS One complete and nine partial responses were observed (response rate, 23%; 95% confidence interval [CI], 10% to 36%). The median response duration was 6 months (range, 2 to 13). The median survival time was 10.4 months and the 1-year survival rate was 46% (95% CI, 39% to 53%). Grade 4 diarrhea occurred in four of the first nine patients (44%) treated on this study at the 150-mg/m2 dose level. The study was amended to reduce the starting dose of irinotecan to 125 mg/m2. At this dose, nine of 39 patients (23%) developed grade 4 diarrhea. Aggressive administration of loperamide also reduced the incidence of grade 4 diarrhea. Grade 4 neutropenia occurred in eight of 48 patients (17%), but was associated with bacteremia and sepsis in only case. CONCLUSION Irinotecan has significant single-agent activity against colorectal cancer that has progressed during or shortly after treatment with 5-FU-based chemotherapy. The incidence of severe diarrhea is reduced by using a starting dose of irinotecan 125 mg/m2 and by initiating loperamide at the earliest signs of diarrhea. These results warrant further clinical evaluation to define the role of irinotecan in the treatment of individuals with colorectal cancer.

PURPOSE To evaluate the effect of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy alone and of ABVD with mantle or mediastinal irradiation (RT) on the pulmonary function of patients with early-stage Hodgkin's disease. PATIENTS AND METHODS Between 1989 and 1993, 60 patients with clinical stage I to IIIA HD enrolled onto randomized trials at Memorial Sloan-Kettering Cancer Center (MSKCC) underwent prospective evaluation of pulmonary function. All patients received six cycles of ABVD, and 30 patients received mantle or mediastinal RT. Pulmonary function tests (PFTs) and symptom evaluation were conducted before, during, and after completion of chemotherapy and RT, and at various intervals thereafter. The median follow-up time was 30 months. RESULTS During chemotherapy, symptoms of cough and dyspnea on exertion developed in 32 of 60 patients (53%) and declines in pulmonary function occurred in 22 of 60 patients (37%). Discontinuation of bleomycin was necessary in 14 of 60 patients (23%). Following chemotherapy, there was a significant decline in median forced vital capacity (FVC) and diffusing capacity of carbon monoxide (DLCO). In patients who received mantle or mediastinal RT, there was a further decline in FVC following radiation therapy. At the most recent follow-up evaluation, five of 29 patients (18%) who received ABVD alone and nine of 30 (30%) who received ABVD and RT reported persistent mild pulmonary symptoms (P = .36), which did not significantly affect normal daily activity. CONCLUSION ABVD chemotherapy induced acute pulmonary toxicity that required bleomycin dose modification in a substantial number of patients. The addition of RT resulted in a further decrease in FVC; however, this did not significantly affect the functional status of patients.

PURPOSE To review antibody structure, function, and production; suitable radioisotopes for radioimmunotherapy; challenges facing the field; recent clinical results; toxicity; and future directions. DESIGN The radioimmunotherapy literature was reviewed, with an emphasis on clinical results and future directions. RESULTS The highest complete response rates (overall, approximately 50%) have been achieved in patients with B-cell non-Hodgkin's lymphoma. Challenges that currently face radioimmunotherapy include circulating free antigen, binding of antibodies to nonspecific Fc receptors, insufficient tumor penetration, antigenic heterogeneity and insufficient antigen expression, antigenic modulation, and development of human antimouse antibodies. Possible approaches to these challenges, including high-dose radioimmunotherapy and chemotherapy followed by autologous bone marrow transplantation, the use of radionuclides such as yttrium 90 (90Y) and copper 67 (67Cu), and the development of humanized and bifunctional antibodies, are under investigation. CONCLUSION Although radioimmunotherapy is a relatively new field, substantial progress has been made. Additional research will ultimately resolve many of the challenges that currently face radioimmunotherapy and hopefully lead to the cure of some currently incurable malignancies.

PURPOSE To test intensive alkylator-based therapy in desmoplastic small round-cell tumor (DSRCT). PATIENTS AND METHODS Patients received the P6 protocol, which has seven courses of chemotherapy. Courses 1, 2, 3, and 6 included cyclophosphamide 4,200 mg/m2, doxorubicin 75 mg/m2, and vincristine (HD-CAV). Courses 4, 5, and 7 consisted of ifosfamide 9 g/m2 and etoposide 500 mg/m2 for previously untreated patients, or ifosfamide 12 g/m2 and etoposide 1,000 mg/m2 for previously treated patients. Courses started after neutrophil counts reached 500/microL and platelet counts reached 100,000/microL. Tumor resection was attempted. Post-P6 treatment options included radiotherapy and a myeloablative regimen of thiotepa (900 mg/m2) plus carboplatin (1,500 mg/m2), with stem-cell rescue. RESULTS Ten previously untreated and two previously treated patients have completed therapy. The male-to-female ratio was 11:1. Ages were 7 to 22 years (median, 14). The largest masses were infradiaphragmatic (n = 11) or intrathoracic (n = 1). Other findings included serosal implants (n = 11), regional lymph node invasion (n = 8), ascites or pleural effusion (n = 7), and metastases to liver (n = 5), lungs (n = 4), distant lymph nodes (n = 3), spleen (n = 2), and skeleton (n = 2). Tumors uniformly responded to HD-CAV, but there were no complete pathologic responses. One patient died at 1 month from tumor-related Budd-Chiari syndrome. Of seven patients who achieved a complete remission (CR), five remain in CR 9, 12, 13, 33, and 38 months from the start of P6, one patient died of infection at 12 months (autopsy-confirmed CR), and one patient relapsed 4 months off therapy. Of four patients who achieved a partial remission (PR), one remains progression-free at 34 months and three developed progressive disease. Five patients received local radiotherapy: three were not assessable for response, but in two patients, antitumor effect was evident. Four patients received thiotepa/carboplatin: two were in CR and remain so, and two patients had measurable disease that did not respond. CONCLUSION For control of DSRCT, our experience supports intensive use of HD-CAV, aggressive surgery to resect visible disease, radiotherapy to high-risk sites, and myeloablative chemotherapy with stem-cell rescue in selected cases.

PURPOSE To describe the treatment of retinoblastoma at a single institution using a prospective protocol based on histopathologic staging. PATIENTS AND METHODS We included 116 consecutive patients (101 eligible, 46 bilateral) from August 1987 to December 1993. Treatment was enucleation or conservative therapy for intraocular disease (stage I patients). Stage II patients (orbital or postlaminar invasion) received vincristine, cyclophosphamide, and doxorubicin for 57 weeks. Patients with orbital mass and extension beyond the cut end of the optic nerve also received orbital radiotherapy (45 Gy). The latter received intrathecal therapy. In those with CNS (stage III) or hematogenous metastasis (stage IV), cisplatin and etoposide were added along with cranial (in patients with a CNS mass and prophylactically in stage IV) or craniospinal (in patients with positive CSF) radiotherapy. RESULTS The median follow-up time was 39 months (range, 12 to 84). The overall survival rate was 0.84. Survival rates according to stage were as follows: stage I probability of overall survival [pOS] = 0.97) (alive/total), 59 of 60; stage II (pOS = 0.85) including patients with scattered episcleral cells, three of three; orbital mass, one of one; postlaminar invasion up to and beyond the cut end of optic nerve, 10 of 11 and 11 of 14, respectively; of stage III (pOS = 0), zero of six; and stage IV (pOS = 0.50), three of six. Only those patients with preauricular adenopathy as the only metastatic site survived in the latter group. Acute toxicity was mild. CONCLUSION Chemotherapy is not warranted to prevent systemic metastasis for intraocular disease. Patients with extraocular orbital disease and had a good outcome with this therapy. Patients with metastatic disease fared poorly, except for those with isolated malignant preauricular adenopathy.

PURPOSE To produce definitions based on serial CA 125 levels to measure response of ovarian carcinoma in patients receiving first-line chemotherapy. PATIENTS AND METHODS Definitions were derived from analysis of 277 patients in North Thames Ovary Trial 3. Patient data were then incorporated into a computer program and tested against 254 patients in North Thames Ovary Trial 4 and 458 patients in Gynecologic Oncology Group (GOG) protocol 97. For optimum detection of response, three response definitions have been combined into a computer program. The precise definitions use mathematic logic and take account of factors such as intervening samples. Response to a specific treatment has occurred if after two samples there has been a 50% decrease, confirmed by a fourth sample (50% response), or a serial decrease over three samples of greater than 75% (75% response). The final sample has to be at least 28 days after the previous sample. RESULTS Six hundred twenty of 989 patients were considered assessable for response according to CA 125 level. Only two patients (0.3%) had a CA 125 response at the time of clinical progression. The CA 125 response rate was 62% and 54% in the North Thames trials. In the GOG trial, it was 66% in all 317 patients assessable for CA 125 and 67% in 221 patients whose CA 125 level was not measurable according to GOG criteria, compared with a GOG-defined response rate of 62%. The sensitivity for detecting GOG-defined response was at least 68%. CONCLUSION Definitions based on a 50% or 75% decrease of CA 125 levels have been shown reliably to define partial response of ovarian cancer in patients receiving first-line chemotherapy. These definitions should be used in addition to or instead of standard response criteria.
Conservative treatment versus mastectomy in early breast cancer: patterns of failure with 15 years of follow-up data. Institut Gustave-Roussy Breast Cancer Group.

PURPOSES A randomized trial was conducted to compare tumorectomy and breast irradiation with modified radical mastectomy. We have analyzed the patterns of failure in each arm of the trial and the prognostic factors that have an independent effect on treatment failures and overall survival. PATIENTS AND METHODS The trial included 179 patients with breast cancer of up to 20 mm in diameter at macroscopic examination. Eighty-eight patients had conservative management and 91 a mastectomy. All patients had axillary dissection with frozen-section examination. For patients with positive axillary nodes (N+), a second randomization was performed: lymph node irradiation versus no further regional treatment. Patterns of failure were determined by a competing-risk approach and multivariate analysis. A prognostic-score was determined by multivariate analysis. RESULTS Overall survival, distant metastasis, contralateral breast cancer, new primary malignancy, and locoregional recurrence rates were not significantly different between the two surgical groups, or between lymph node irradiation groups. Most recurrences appeared during the first 10 years. Three distinct prognostic groups were determined taking into account age, tumor size, histologic grading, and number of positive axillary nodes. CONCLUSION Long-term results support conservative treatment with limited surgery and systematic breast irradiation as a safe procedure for the management of small breast cancers. Four easily obtainable clinical and histologic factors may be combined in a prognostic score that is highly predictive of overall and event-free survival.

PURPOSE To compare two cyclophosphamide, methotrexate, fluorouracil, vincristine, and prednisone (CMFVP) regimens with a doxorubicin-based regimen--vinblastine, doxorubicin, thiotepa, and Halotestin (Upjohn, Kalamazoo, MI) (VATH)--in patients with stage II node-positive breast carcinoma. METHODS Nine hundred forty-five women were treated with a 6-week induction course of CMFVP. They were then randomized to receive one of two consolidation CMFVP regimens: 6-week courses or 2-week courses. Following completion of CMFVP consolidation, patients were again randomized to either continue the CMFVP regimen or to receive six escalating doses of VATH. RESULTS Among all patients, with a median follow-up time of 11.5 years, there is no statistically significant difference in disease-free survival (DFS) between the two consolidation CMFVP regimens. VATH intensification treatment is statistically significantly superior to CMFVP in terms of DFS (P = .0040). For patients with one to three involved nodes, there is currently no significant difference between VATH and CMFVP; however, among those with four or more positive lymph nodes, there is a significant difference in favor of VATH (P = .0037). There is also improved overall survival with VATH (P = .043; median, > 14 years v 10 years). This difference is also statistically significant in patients with four or more involved lymph nodes, among postmenopausal patients, and among postmenopausal estrogen receptor-positive patients. CONCLUSION Chemotherapy with crossover to escalating doses of VATH following CMFVP was well tolerated and effective. Inauguration of VATH as a treatment intensification at the eighth month produced a major increase in relapse-free and overall survival. The observation that sensitivity to VATH is retained so long after mastectomy raises questions about the proper duration of adjuvant chemotherapy and lends support to further investigation of cross-over designs in future trials to postoperative adjuvant chemotherapy regimens.

PURPOSE To assess the role of radioimmunoguided surgery (RIGS) using a handheld intraoperative gamma-detecting probe (GDP) to identify neoplastic disease after primary chemotherapy in locally advanced breast cancer (LABC) patients injected with iodine 125-labeled monoclonal antibodies (MAbs). PATIENTS AND METHODS Twenty-one patients with histologically documented LABC were treated with a combined modality approach. After three courses of primary chemotherapy and before modified radical mastectomy, the 125I-radiolabeled MAbs B72.3 (anti-TAG72) and FO23C5 (anti-carcinoembryonic antigen [CEA]) were administered to 11 patients (group A) and 10 patients (group B), respectively. At surgery, a GDP was used to locate the primary tumor and to assess possible tumor multicentricity and the presence of ipsilateral axillary metastases. Routine pathologic examination was performed in neoplastic and normal tissue specimens of all 21 patients. In addition, immunohistochemical assay for TAG72 and CEA expression was performed. RESULTS In group A patients, RIGS identified primary tumor in seven of 11 patients (63.3%) and unpalpable multicentric tumor lesions were located in two of four (50%). Positive axillary lymph nodes were histologically documented in eight of 11 patients (72.7%) and RIGS identified three of eight (37.5%). In group B, RIGS located the primary tumor lesion in four of 10 patients (40%); in two cases, the tumor was not clinically evident. Multicentricity was observed in one of two patients and lymph node involvement in three of nine (33.3%). No false-positive results were observed in either group A or B. CONCLUSION RIGS appears to be a safe and reliable technique. However, the MAbs used in this study are not sufficiently specific. RIGS represents a technique for which the full potential for intraoperative assessment of breast cancer lesions can be reached when more specific antibodies become readily available.
