Independent factors predict supranormal CA 15-3 serum levels in advanced breast cancer patients at first disease relapse.

Data currently available are insufficient to demonstrate a real utility for CA 15-3 in the diagnosis, staging or surveillance of breast cancer patients following primary treatment. The aim of this study was to determine if there was a correlation between supranormal CA 15-3 serum levels and clinical and biological variables in breast cancer patients at first disease relapse. From October 1988 to March 1998, 430 consecutive patients entered the study. Overall CA 15-3 sensitivity was 60.7%. Elevated CA 15-3 levels were found more frequently in patients with liver metastases (74.6%) and in those with pleural effusion (75.7%). CA 15-3 sensitivity was 70.4% in patients with estrogen-receptor-positive (ER+) primary tumors and 45.9% in those with estrogen-receptor-negative (ER-) tumors (p < 0.0001). In patients with a limited extent of disease, marker sensitivity was 57.7% in ER+ tumors and 25.7% in ER- tumors (p < 0.0001). Logistic regression analysis showed ER status, disease extent and pleural effusion as independent variables associated with CA 15-3 positivity. The multivariate Cox analysis showed ER and disease extent as independent variables predicting overall survival, whereas CA 15-3 failed to be statistically significant. CA 15-3 was an independent variable only when the disease extent variable was removed. This study suggests that CA 15-3 in advanced breast cancer patients is a marker of both disease extent and ER status. The direct relationship with ER status indicates that CA 15-3 diagnostic sensitivity in the early detection of disease recurrence could be greater in ER+ patients than in ER- ones. Furthermore, this suggests that patients with elevated CA 15-3 levels could have disease that is more sensitive to hormone manipulation than those with normal CA 15-3 values.

Low dose carboplatin (AUC 4.5) combined with vinorelbine in the treatment of advanced non-small cell lung cancer: a single institution phase II study.

Platinum compounds and vinorelbine (VNB) are active in the treatment of non-small cell lung cancer (NSCLC), but moderate toxicity has been reported. The aims of the present study were to assess activity and tolerability of low dose carboplatin (CBDCA): 4.5 AUC according to Calvert formula on day 1, combined with vinorelbine: 25 mg/m2 on days 1 and 8, administered every 4 weeks. Eighty-five advanced NSCLC patients entered the study; all of them were evaluable for toxicity and 83 were evaluable for activity. According to an intent to treat analysis, 26 patients attained a partial response (30.5%; 95% CI 20.5-40.5), 27 (31.7%) obtained a disease stabilization and 30 (35%) progressed. This regimen appeared to be modestly toxic, grade 3-4 leukopenia and thrombocytopenia were observed in less than 5% of cases and grade 2 neuropathy in 10% of cases. Median time to progression and overall survival were 7 and 9 months, respectively. In conclusion, low dose CBDCA (administered following Calvert's formula) and VNB combination is an active and very well tolerated cytotoxic regimen in the treatment of advanced NSCLC. The application of the Calvert formula may have contributed to limit the side effects related to CBDCA.

Gemcitabine plus cisplatin in the treatment of patients with advanced non-small cell lung cancer: a phase II study.

BACKGROUND: Lung cancer is the leading cause of cancer death in men worldwide; most cases are not suitable for radical surgery at diagnosis and palliative treatment remains the primary goal of therapy. Cisplatin and gemcitabine are among the most active cytotoxic agents for the treatment of non-small cell lung cancer (NSCLC): they have non-overlapping toxicity and preclinical studies have demonstrated their potential synergistic interaction. PATIENTS AND METHODS: The aims of the present study were to assess the activity and tolerability of cisplatin 80 mg/m2 on day 1, combined with gemcitabine 1000 mg/m2 on days 1 and 8, administered every 3 weeks. A total of 46 consecutive patients with advanced NSCLC entered this study; all of them were evaluable for toxicity and for activity. RESULTS: According to an intent-to-treat analysis, 15 patients attained a partial response (33%), 9 (20%) obtained a disease stabilisation and 22 (47%) progressed. This regimen appeared to be modestly toxic, with grades 3-4 leukopenia and thrombocytopenia observed in 10% and 6% of cases respectively; grade 3 vomiting appeared in 12 patients (26%) and grade 3 mucositis in 1 patient. The median time-to-progression and overall survival were 200 and 400 days, respectively. CONCLUSION: Our study of gemicitabine + cisplatin on stage IV NSCLC patients achieved favourable results in terms of toxicity and overall survival.
