PURPOSE In prior Cancer and Leukemia Group B (CALGB) studies, combined chemotherapy and thoracic irradiation was superior to chemotherapy alone in limited-disease (LD) small-cell lung cancer (SCLC). A combined modality pilot study was performed to test the feasibility of adding warfarin to aggressive chemoradiotherapy for LD SCLC. PATIENTS AND METHODS Combination chemotherapy with doxorubicin 45 mg/m2 intravenously (IV) on day 1, cyclophosphamide 800 mg/m2 IV on day 1, and etoposide (ACE) 80 mg/m2 on days 1 to 3 was given every 21 days for the first three courses. The fourth and fifth courses substituted cisplatin 33 mg/m2 IV on days 1 to 3 for the doxorubicin, with concurrent chest irradiation to a total of 4,000 cGy given in 20 fractions during a 4-week period followed by a boost of 1,000 cGy in five fractions during a 1-week period. Prophylactic cranial irradiation, 3,000 cGy was given concurrently in 10 fractions during a 2-week period. Courses 6 to 8 again used ACE chemotherapy, but courses 4 to 8 were given on a 28-day schedule with dose adjustment for hematologic or renal toxicity. Warfarin was given throughout the treatment period titrated to achieve a prothrombin time (PT) of 1.5 to 2 times the control. Patients with histologically proven limited-stage SCLC, good performance status, and normal renal, hematologic, and hepatic functions were eligible. RESULTS Sixty-one of 66 patients entered onto the study were eligible and assessable. Fifty-four (89%) (95%) confidence interval [CI], 78% to 95%) experienced an objective response, 35 (57%) achieved a complete response (CR) (95% CI, 44% to 70%), and 17 (28%) achieved a partial response (95% CI, 16% to 39%). Median durations were CR, 26.3 months; failure-free survival, 11.8 months; and survival, 18 months. Forty-one percent of the patients were alive at 2 years, 33% were alive at 3 years, and 25% were alive at 4 or more years. Median follow-up for survivors is 5 years (range, 3.5 to 5.9 years). Severe or life-threatening myelosuppression occurred in 90%, infection occurred in 34%, fever without documented infection occurred in 26%, and pulmonary toxicity occurred in 6%. Another 6% of patients experienced severe or life-threatening hemorrhages. There were four treatment-related fatalities. The pulmonary toxicities have been associated with the resumption of ACE chemotherapy after chest irradiation. CONCLUSIONS These highly encouraging response and survival results compare favorably with any prior CALGB group study. Although they are somewhat more toxic, they are comparable to the best published results. A randomized study that examines the role of warfarin is underway.

The role of etoposide epipodophyllotoxin (VP-16-213) in a combined modality treatment program incorporating local chest irradiation and combination chemotherapy with cyclophosphamide, Adriamycin (Adria Laboratories, Columbus, Ohio), and vincristine has been evaluated in a randomized trial of 165 patients with small-cell lung cancer. The overall response rate (complete response [CR] plus partial response [PR]) was significantly greater in the VP-16-213 arm (85% v 64%, P = .005) primarily as a consequence of improved response in patients with extensive disease (85% v 38%, P = .002 and 30% v 8% for CR only, P = .045). No differences in the response rates were observed in limited disease. The duration of response (months) was greater in the VP-16-213 arm (8.6 v 7.0 overall and 14.4 v 11.5 for CR) but not significantly so. Median survival times (months) were consistently greater in the group receiving VP-16-213 when analyzed according to extent of disease and response (10.6 v 9.5 overall; 15.0 v 13.6 for limited disease; 9.0 v 6.7 for extensive disease; 18.5 v 16.2 for CR overall; and 18.6 v 16.1 for CR in limited disease); the results were not statistically significant. The median survival of extensive disease patients attaining a CR was 15.3 months (range 3.2 to 34.3 + months) in the VP-16-213 arm and 7.4+ and 8.1+ months for the two patients with CR in the other group. Anemia and leukopenia occurred to a greater degree in the four-drug regimen, but no unusual or significant compounding toxicity (ie, neurotoxicity) was observed otherwise. Further investigation of this agent in combination chemotherapy programs for small-cell lung cancer appears to be warranted.

PURPOSE To provide a 10-year update of the experience of the Cancer and Leukemia Group B (CALGB) in the addition of thoracic radiation therapy to chemotherapy in limited-stage small-cell lung cancer. PATIENTS AND METHODS Three hundred ninety-nine patients with limited-stage small-cell lung cancer were randomized to receive thoracic radiation therapy that started on day 1 (arm I) or day 64 of chemotherapy treatment (arm II), or chemotherapy alone with cyclophosphamide, vincristine, and etoposide (later, doxorubicin). Thoracic radiation therapy consisted of 4,000 rad to the tumor and mediastinum with a 1,000-rad boost. All patients received prophylactic cranial radiation to a dose of 3,000 rad. RESULTS Arm I patients had a median survival of 13.04 months, arm II patients 14.54 months, and arm III patients 13.58 months (log-rank test, P = .0072). Median time to clinical failure was 11 months in arm I, 11.21 months in arm II, and 8.7 months in arm III (log-rank test, P = .0004). CONCLUSION With 10 years of follow-up, the two arms that included thoracic radiation therapy remain superior to chemotherapy alone. The addition of thoracic radiation therapy to combination chemotherapy improved both complete response rates and survival, with increased but acceptable toxicity.

PURPOSE Studies by the Veterans Administration Cooperative Studies Program and Cancer and Leukemia Group B (CALGB) suggested that the addition of warfarin to chemotherapy might enhance response and/or survival in small-cell lung cancer (SCLC). This randomized study evaluated the effect of warfarin with chemotherapy and radiation therapy in limited-stage SCLC. PATIENTS AND METHODS Patients were randomized to receive warfarin or no warfarin. All patients received three cycles of doxorubicin, cyclophosphamide, and etoposide (ACE). Cycles 4 and 5 (cisplatin, cyclophosphamide, and etoposide [PCE]) were given concurrently with radiation therapy. Three cycles of ACE were given after chemoradiation therapy, but were discontinued due to a high rate of pulmonary toxicity. RESULTS There were no significant differences in response rates, survival, failure-free survival, disease-free survival, or patterns of relapse between the warfarin-treated and control groups. In patients treated according to the initial design, an increase in failure-free survival seen with warfarin treatment approached significance (P = .07). Preamendment results, while not significant, did not have superimposable treatment survival curves. A landmark analysis at 8 months showed a median survival time after the landmark for complete responders of 33 months with warfarin treatment compared with < or = 13.75 months for complete or partial responders not treated with warfarin (P = .05). Differences between the complete responders in this preamendment population were not significant (P = .103). CONCLUSION Warfarin does not appear to improve outcome significantly in limited-stage SCLC. However, the differences in some variables between populations before the protocol amendment correspond to the favorable effects of anticoagulants observed in previous studies.
