ABSTRACT
PURPOSE: The purpose of this study was to evaluate the treatment result of surgical resection after preoperative chemotherapy in inoperable gastric cancer patients. MATERIALS AND METHODS: We analyzed 18 gastric cancer patients who underwent gastric resection after preoperative chemotherapy because they showed some clinical response to chemotherapy (15 with distant metastasis and 3 with locally advanced lesions). The mean postoperative follow-up period was 15.3+/-15.5 (1~56) months. RESULTS: In 15 patients with distant metastasis, 2 (13.3%) showed complete response (CR), 10 (66.7%) partial response (PR), 2 (13.3%) stable disease (SD), and 1 (6.7%) progressive disease (PD). The clinical response rate was 80.0%. Five subtotal gastrectomies, 4 total gastrectomies, and 6 extended total gastrectomies were performed. Two cases of CR were alive without recurrence for 4 and 26 months, respectively. Mean survival period in PR case was 37.7 months, but 2 cases of SD and 1 case of PD died after 11.7, 17.9, and 0.9 months, respectively. Postoperative survival was significantly associated with the response to chemotherapy (P<0.01). The mean survival period of the 10 patients with a complete resection was 44.1 months, which was significantly better than that of the 5 patients with an incomplete resection (9.8 months, P=0.03). Among 3 patients with locally advanced gastric cancer, 2 cases showed PR to chemotherapy, and complete resection was possible only by gastrectomy for those patients. CONCLUSION: In some selected cases, surgical resection was achievable after preoperative chemotherapy for patients with inoperable metastatic or locally advanced gastric cancer.

PURPOSE: MOPP/ABV hybrid regimen incorporates MOPP and ABVD into a single regimen on the tenets of the Goldie-Coldman hypothesis. This study was performed to determine the efficacy of COPP/ABV hybrid regimen, in which cyclophosphamide was substituted for mechlorethamine, in patients with advanced Hodgkin's disease. MATERIALS AND METHODS: Patients with advanced Hodgkin's disease were treated with cyclophosphamide(600 mg/m2 iv, Dl), vincristine(1.4 mg/m2 iv, D1), procarbazine(100 mg/m2/d po, D1-7), prednisolone(40 mg/m2/d po D1-14), doxorubicin(35 mg/m2 iv, D8), bleomycin(10 mg/m2 iv, D8) and vinblastine(6 mg/m2 iv, D8). The treatment was repeated every 4 weeks. RESULTS: Between Aug. 1989 and Aug. 1996, 28 patients were enrolled. The median age was 33 years. Twenty one(75%) were previously untreated, newly diagnosed patients and 7(25%) were those who had relapsed after previous radiotherapy(RT). The common histologic types were nodular sclerosis(46%) and mixed cellularity(36%). Twenty three (82%) patients achieved complete remission(CR), three(11%) with the assistance of involved-field RT. Only one patient was primary treatment failure. The median follow-up duration was 56 months. Of the 23 patients achieving CR, three(13%) relapsed. Five-year relapse-free survival was 84.4%. Eight patients died. Five-year overall survival rate was 66.6% and 5-year failure-free survival rate was 66.3%. The survival rate of those who had relapsed after previous RT was significantly lower than that of newly diagnosed patients(P=0.03). The hematologic toxicities were common, but nonhernatologic toxicities were uncommon. Five patients died of treatment-related pneumonia or sepsis. Among them, four were those who had relapsed after previous RT. CONCLUSION: COPP/ABV hybrid regimen could cure significant proportion of patients with advanced Hodgkin's disease but the treatment-related mortality was high, especially in those who had relapsed after previous RT. Another regimen should be considered for those who received previous RT.
