Prognostic factors of breast cancer in Koreans / 대한내과학회지

BACKGROUND: The aim of this study is to determine prognostic factors of breast cancer in Korean patients who underwent curative mastectomy. METHODS: Medical records of 181 patients who underwent curative mastectomy were reviewed. Relapse-free survival and overall survival were documented for each patient. Factors influencing survival were analyzed using Cox proportional hazard model. RESULTS: Overall 5-year survival rate was 82.0%, and 8-year survival rate was 74.7%. Multivariate analysis indicated that multiple axillary lymph node involvement (> or =4), postmenopausal status, and negative estrogen receptor were independent adverse prognostic factors. The adjusted relative risks of multiple axillary lymph node involvement (> or =4), postmenopausal status, and negative estrogen receptor were estimated 2.60 (95% Confidence Interval (CI): 1.28-5.30), 2.64 (95% CI: 1.46-4.79), and 2.27 (95% CI: 1.19-4.35), respectively. CONCLUSION: Multiple axillary lymph node involvement (> or =4), postmenopausal status, and negative estrogen receptor were independent adverse prognostic factors in Korean breast cancer patients after curative mastectomy.

A Phase 2 Study with Vinorelbine and Ifosfamide in the Inoperable Non - small Cell Lung Cancer / 대한암학회지

PURPOSE: A phase II study of vinorelbine and ifosfamide combination chemotherapy in patients with advanced or recurrent non-small cell lung cancer (NSCLC) was conducted to assess response rate, response duration, and toxicites. MATERIALS AND METHODS: Patients with advanced NSCLC who had no prior systemic chemotherapy were eligible. They have no central nervous system metastasis and recurrent or progressive disease after surgery or radiotherapy. Each cycle consisted of vinorelbine 25 mg/m' i.v. days 1 & 8, and ifosfamide 2 g/m i.v. days 1, 2 & 3 with Mesna and treatments were repeated every 21 days. RESULTS: Forty patients with advanced or recurrent NSCLC were treated at multi center between March, 1997 and March, 1998. Six patients were not evaluable because five patients refused therapy after the first course and one patient was protocol violation. Of 34 evaluable patients, objective responses were seen in 11 (32.4%) patients (CR 0%, PR 32.4%). The median duration of response was 16.4 weeks. The median overall survival was 9.5 months. The toicities of this regimen were acceptable without treatment related toxic death. CONCLUSION: We concluded that combination regimen of vinorelbine and ifosfamide was effective and tolerable in the treatment of advanced non-small cell lung cancer.

Patterns of the First Failure after Curative Resection of Gastric Cancer in Korean Female Patients / 대한암학회지

PURPOSE: The major aim of this study is to evaluate the patterns of recurrence of the stomach cancer after curative resection. MATERIALS AND METHODS: Patterns of the fimt failure and survival after relapse of 136 female gastric cancer patients who had received curative resection were evaluated. Factors influencing survival after relapse were analyzed using Cox proportional hazard model. RESULTS: Peritoneal relapse was the most common pattern of the first failure, with 3-year estimate of overall peritoneal relapse being 13.0%. The 3-year estimates of overall local- regional relapse, liver metastasis, and extraabdominal relapse were 11.2%, 4.8%, and 3.8%, respectively. Patients younger than 45 years developed peritoneal relapse at a significantly higher rate than patients aged 45-65 years (p 0.037). The most significant factor affecting the survival of relapsed patients was whether resection was performed for recurrent disease without remaining gross residual disease. Patterns of relapse did not significantly affect survival, but patients whose recurrences were limited to local-regional area tended to survive longer than those with extraaMominal component (p=0.067). CONCLUSION: Peritoneal relapse was the most common pattem and significantly associated with younger age after curative resection af gastric cancer of Korean female patients.
