Chemotherapy for non-small-cell lung cancer (NSCLC) remains controversial. We describe the two largest reported, randomized, parallel trials designed to determine whether the addition of chemotherapy influences duration and quality of life in localized, unresectable (mitomycin, ifosfamide, cisplatin [MIC]1 trial) and extensive (MIC2 trial) disease.
                Ambulatory patients with NSCLC, aged 75 years or younger, with localized disease, were randomized in MIC1 to receive up to four cycles of chemotherapy (CT: mitomycin 6 mg/m(2), ifosfamide 3 g/m(2), and cisplatin 50 mg/m(2)) every 21 days, followed by radical radiotherapy (CT + RT) or radiotherapy (RT) alone. Extensive-stage patients were randomized in MIC2 to identical chemotherapy plus palliative care (CT + PC) or palliative care (PC) alone. Short-term change in quality of life (QOL) was assessed in a subgroup of patients. Data from the two trials were combined to allow multivariate and stratified survival analyses.
                Seven hundred ninety-seven eligible patients were randomized, 446 in MIC1 and 351 in MIC2. MIC CT improved survival in both trials (significantly in MIC2). The median survival time in MIC1 was 11.7 months (CT + RT) versus 9.7 months (RT alone) (P =.14); whereas in MIC2, median survival time was 6.7 months (CT + PC) compared with 4. 8 months (PC alone) (P =.03). QOL, assessed in 134 patients from start of trial to week 6, showed improvement with chemotherapy and deterioration with standard treatment. In the combined analysis of 797 randomized patients, the positive effect of MIC on survival was significant overall (P =.01) and after adjusting for prognostic factors (P =.01).
                MIC chemotherapy prolongs survival in unresectable NSCLC without compromising QOL. In premenopausal women with metastatic breast cancer, differences in survival curves early during follow-up can be misleading. The authors therefore analyzed long-term survival in 378 patients, entered in three randomized trials, started between 1973 and 1978. Combined data from the three trials were used to increase the power for identifying prognostic variables. Cancer and Leukemia Group B (CALGB) trial 7382 randomized patients to oophorectomy plus either cyclophosphamide or combination chemotherapy or observation. Eastern Cooperative Oncology Group (ECOG) 2174 randomized patients who had not progressed 3 months after oophorectomy to combination chemotherapy or combination chemotherapy or observation. Trial ECOG 2177 randomized estrogen receptor (ER) positive or ER-unknown patients to oophorectomy plus combination chemotherapy or immediate combination chemotherapy, and ER-negative patients were directly assigned to combination chemotherapy. Hence ER-negative patients need not have been healthy enough to be randomized to oophorectomy. With only 14% of the patients still alive, median survival on the three studies was 30, 24, and 28 months. The median survival of individual treatments changed noticeably in ECOG 2174 and ECOG 2177 with long-term follow-up. At this time there are no differences in survival between randomized regimens in any of the three trials. In a multivariate model, factors associated with significantly poorer survival were visceral-dominant disease, nodal metastases, breast metastases, age younger than 45 years, ER negativity, and not receiving chemotherapy immediately after oophorectomy. This treatment difference was thus not due to imbalances in the prognostic variables used in the model, but it may be due to imbalances of unknown prognostic factors or differences in patient selection. A Nordic multicenter study in asymptomatic patients with advanced colorectal cancer compared initial chemotherapy with sequential methotrexate-5-FU with leucovorin rescue (MFL) for 6 months versus primary expectancy with chemotherapy only after the appearance of symptoms. The study (183 patients randomized between January 1985 and February 1990) showed that symptom-free survival, progression-free survival and survival respectively were about 6 months longer in the group of patients randomized to initial MFL. Whether these prolongations could be achieved without an impaired 'quality of life' was studied in an associated study. Between January 1985 and March 1987, 43 patients were randomized at one of the hospitals, 36 of which were interviewed with a questionnaire at randomization. Even if all these patients were considered, by the physician, to be 'free of symptoms from their disease', 16/36 (44%) had symptoms that could be referred to the disease. In spite of this, the patients were in a good general condition, and considerably better off than patients considered to have 'symptoms from the disease' who were interviewed with the same questionnaire when randomized in a parallel study of symptomatic patients. Patients randomized to initial chemotherapy and interviewed longitudinally maintained their good condition throughout treatment. Toxicity was mild, although the patients expressed more adverse effects than the physicians recorded. Since symptom-free survival, progression-free survival and survival were statistically significantly longer in the group of patients randomized to MFL also in this associated study, it is concluded that initial chemotherapy can prolong symptom-free survival and survival without reduced 'quality of life' during the treatment period. Four hundred twenty-nine patients were entered into four prospective randomized clinical studies between January 1, 1973, and July 1, 1979. The records of 395 of these were analyzed to determine the proportion of patients surviving 48 months after therapy initiation. Ninety-six patients (24%) were living at 48 months, 89 of whom had second-look laparotomies. Of the 96 living patients, 53 (55%) were clinically free of disease and 43 (45%) had disease. Combination-agent chemotherapy produced a larger proportion of 48-month survivors than single-agent therapy (P = 0.001); 70% of these survivors were clinically free of disease. Patient characteristics, such as age, International Federation of Gynaecology and Obstetrics (FIGO) stage, histologic grade of tumor, and amount of residual tumor present prior to chemotherapy exerted a strong influence on length of survival. Long-term survival was not totally dependent on a complete response to chemotherapy; in fact, persistent treatment with drug regimens induced bone marrow disorders and death due to toxicity in five patients. The continued fall in survival curves after 48 months suggests that current therapy regimens are not dramatically changing long-term survival rates. This paper is a retrospective analysis of patients with clinical Stage I non-small cell carcinoma of the lung treated with definitive radiation therapy alone. The results of therapy, patterns of failure and the relationship of technical aspects of the delivery of radiotherapy to outcome are presented.
                From 1980 through 1990, 53 patients with Stage I non-small cell lung cancer were treated with definitive radiation therapy alone at the Radiation Oncology Center of the Mallinckrodt Institute of Radiology and its affiliated hospitals. All patients had a pathologic diagnosis of non-small cell lung cancer and were not candidates for surgical resection because of either patient refusal (10 patients), poor performance status (5 patients), or premorbid medical problems (38 patients). The median age was 73 years. Histologic cell type included squamous (32), adenocarcinoma (11), large cell (4), and unclassified non-small cell (6). Initial tumor size was < or = 3 cm in 23 patients, between 3 and 5 cm in 13 patients and > or = 5 cm in 17 patients. Diagnostic staging varied during the study period. All patients had chest X-rays and computed tomography scans of the chest. A majority had liver and bone scans, but only four underwent mediastinoscopy. The radiation therapy was of megavoltage energy in all patients, with a median primary prescription tumor dose of 63.2 Gy. Survival was measured from the date radiation therapy was initiated.
                The actuarial overall survival rate for the entire group was 19% at 3 years and 6% at 5 years, with a median survival time of 20.9 months. Of the 49 deaths, 35 died of lung cancer; 13 died of intercurrent illness, and one died of pancreatic cancer, which made the actuarial cause-specific survival 33% at 3 years and 13% at 5 years. The actuarial 3-year disease-free survival was 33%. Local primary tumor progression occurred in 22 patients, resulting in a 51% 3-year actuarial freedom from local progression. An additional four patients failed in regional lymph nodes that were included in the original treatment portals. Multivariate analysis found only T stage to be associated with overall survival (p = .02). However multivariate analysis showed age as a prognostic factor to be approaching statistical significance (p = .07). Patients under 70 years of age showed an increased survival rate compared to patients over 70 years. Radiation therapy doses > or = 65 Gy appeared to result in a decreased proportion of patients dying of lung cancer with no apparent increase in either acute or long-term complication rates.
                Results of definitive radiation therapy for inoperable Stage I non-small cell lung remain inferior to surgical therapy. Potential methods to improve local control with radiotherapy are discussed. To determine whether efaproxiral, an allosteric modifier of hemoglobin, improves quality of life and quality of survival in patients with primary breast cancer and brain metastases when used as an adjunct to whole-brain radiation therapy (WBRT).
                Patients with brain metastases from breast cancer were randomly assigned to receive WBRT and either efaproxiral or no efaproxiral. The primary endpoint for this analysis was quality of life and quality-adjusted survival. Quality of life was assessed prior to initiation of WBRT and periodically in follow-up using the Spitzer Quality of Life Index (SQLI).
                A subgroup of 106 eligible breast cancer patients with baseline SQLI were randomized into this study and represent the target population discussed in this report. Treatment, age, and SQLI were significant predictors of survival. The addition of efaproxiral to WBRT reduced the death rate by 46% (P = 0.0086). Quality of life was improved in the WBRT + efaproxiral arm compared with the WBRT alone arm (P = 0.019). Quality-adjusted survival was statistically significantly improved by the addition of efaproxiral to WBRT (P = 0.001).
                Survival, quality of life, and quality-adjusted survival were all improved in breast cancer patients with brain metastases receiving efaproxiral and WBRT compared with those receiving WBRT alone. The present study compared the intracranial control rate and quality of life for two radiation fractionation schemes for cerebral metastases.
                A total of 113 patients with a Eastern Cooperative Oncology Group performance status <3; and stable (>2 months), absent, or concurrent presentation of extracranial disease were randomized to 40 Gy in 20 twice-daily fractions (Arm A) or 20 Gy in four daily fractions (Arm B), stratified by resection status. The European Organization for Research and Treatment of Cancer Quality of Life 30-item questionnaire was administered monthly during Year 1, bimonthly during Year 2, and then every 6 months to Year 5.
                The patient age range was 28-83 years (mean 62). Of the 113 patients, 41 had undergone surgical resection, and 74 patients had extracranial disease (31 concurrent and 43 stable). The median survival time was 6.1 months in Arm A and 6.6 months in Arm B, and the overall 5-year survival rate was 3.5%. Intracranial progression occurred in 44% of Arm A and 64% of Arm B patients (p = .03). Salvage surgery or radiotherapy was used in 4% of Arm A patients and 21% of Arm B patients (p = .004). Death was attributed to central nervous system progression in 32% of patients in Arm A and 52% of patients in Arm B (p = .03). The toxicity was minimal, with a minor increase in short-term cutaneous reactions in Arm A. The patients' quality of life was not impaired by the more intense treatment in Arm A.
                Intracranial disease control was improved and the quality of life was maintained with 40 Gy in 20 twice-daily fractions. This schema should be considered for better prognosis subgroups of patients with cerebral metastases.

                A total of 156 patients with Stage IA-B Grade 3 (n=28), or Stage IC-IIIA Grade 1-3 (n=128) were postoperatively randomized to receive radiotherapy (56 Gy) only (Group A, n=72) or radiotherapy combined with three courses of cisplatin (50 mg/m(2)), epirubicin (60 mg/m(2)) and cyclophosphamide (500 mg/m(2)) (Group B, n=84).
                The disease-specific overall five-year survival was in Group A 84.7% vs. 82.1% in Group B (p=0.148). The median disease-free survival in A was 18 (range 9-36) months and 25 (range 12-49) months in B (p=0.134), respectively. During a five-year follow-up 32 patients relapsed. Of the recurrences 5 were local and 20 distant, while 7 were combined. As calculated from the operation, the median time to recurrence was 15 (range 6-37) months in Group A, and 20 (range 8-60) months in Group B, respectively (p=0.170). Twenty-six patients died of the disease during the five-year follow-up, 11 in A and 15 in B. The patients succumbing in A lived a median 23 (range 15-44) months as compared to 37 (range 13-50) months in B (p=0.148). Chemotherapy was associated with an acceptable rate of acute toxicity. Less than 8% of the patients complained of Grade 3/4 nausea. The rate of Grade 3/4 leucopenia was at the highest at 16.6% during the third cycle but only 6.2% of the patients had Grade 3 infection. A total of 10 patients developed intestinal complications demanding surgery, 2 in Group A (2.7%) and 8 (9.5%) in Group B, respectively.
                Adjuvant chemotherapy with cisplatin, epirubicin and cyclophosphamide failed to improve overall survival or lower the recurrence rate in patients operated on and radiated for high-risk endometrial carcinoma. Chemotherapy was associated with a low rate of acute toxicity but appeared to increase the risk of bowel complications. This review was initiated to assess the outcome of treatment with radical radiotherapy with curative intent for patients diagnosed as having stage I non-small cell lung cancer. The study involved a retrospective review of 347 patients with T1 and T2N0M0 tumors treated at the Queensland Radium Institute during the period 1985 to 1992. The main reasons for not proceeding to surgery included poor performance status, old age, or refusal to submit to surgery. The median age for the group was 70 years, with the range being 34 to 90 years. Patients in this group were all treated by a standard technique involving external-beam radiotherapy to 50 Gy, minimum tumor dose, in 20 fractions over 4 weeks. The overall survival rate was 27% at 5 years with a median survival of 27.9 months. The 5-year recurrence-free survival was 23% with the median being 19.5 months. There was a strong correlation of survival to tumor size with 5-year survival rates being 32% and 21% for T1 and T2 tumors, respectively. Multivariate analysis found only T stage to be associated with overall survival (p < 0.01). In addition, the analysis showed that age younger than 70 years was a prognostic factor that approached statistical significance at the p < 0.05 level of significance. We conclude from this large series of patients with stage I non-small cell lung cancer that radical radiotherapy with curative intent may be a viable alternative to surgery in those patients who either refuse surgery or are judged to be unfit for operation.
MAB produces a modest overall and cancer-specific survival at five years but is associated with increased adverse events and reduced quality of life.
