- Systematic reviews have found that luteinizing hormone-releasing hormone (LHRH) agonists are effective in treating premenopausal women with early breast cancer.We conducted long-term follow-up (median 12 years) of 2706 women in the Zoladex In Premenopausal Patients (ZIPP), which evaluated the LHRH agonist goserelin (3.6 mg injection every 4 weeks) and tamoxifen (20 or 40 mg daily), given for 2 years. Women were randomly assigned to receive each therapy alone, both, or neither, after primary therapy (surgery with or without radiotherapy/chemotherapy). Hazard ratios and absolute risk differences were used to assess the effect of goserelin treatment on event-free survival (breast cancer recurrence, new tumor or death), overall survival, risk of recurrence of breast cancer, and risk of dying from breast cancer, in the presence or absence of tamoxifen.Fifteen years after the initiation of treatment, for every 100 women not given tamoxifen, there were 13.9 (95% confidence interval [CI] = 17.5 to 19.4) fewer events among those who were treated with goserelin compared with those who were not treated with goserelin. However, among women who did take tamoxifen, there were 2.8 fewer events (95% CI = 7.7 fewer to 2.0 more) per 100 women treated with goserelin compared with those not treated with goserelin. The risk of dying from breast cancer was also reduced at 15 years: For every 100 women given goserelin, the number of breast cancer deaths was lower by 2.6 (95% CI = 6.6 fewer to 2.1 more) and 8.5 (95% CI = 2.2 to 13.7) in those who did and did not take tamoxifen, respectively, although in the former group the difference was not statistically significant.Two years of goserelin treatment was as effective as 2 years of tamoxifen treatment 15 years after starting therapy. In women who did not take tamoxifen, there was a large benefit of goserelin treatment on survival and recurrence, and in women who did take tamoxifen, there was a marginal potential benefit on these outcomes when goserelin was added.

- HYPOTHESIS: The objective of the study was to analyze if C-reactive protein (CRP) and smoking status provide prognostic information in patients with advanced non-small cell lung cancer (NSCLC) receiving palliative first-line chemotherapy. METHODS: Retrospective, single-institutional study, comprising all patients with NSCLC stage IIIB/IV and World Health Organization performance status (PS) 0-2 who started palliative first-line chemotherapy between January 1, 2002, and January 31, 2007. Patient records were reviewed. Cox's proportional hazards model was used to identify prognostic factors. RESULTS: Two hundred eight-nine consecutive patients were evaluable. Sixty-eight percent had stage IV disease and 67% had PS 0 or 1. Median survival was 7.4 months. At onset of chemotherapy, 206 patients (71%) had elevated CRP values (> or = 10 mg/liter). One-hundred-forty-four patients (50%) were current smokers. On univariate analysis, patients with elevated CRP levels had inferior survival (hazard ratio [HR] = 1.67, 95% confidence interval [CI], 1.28-2.19, p < 0.001). Smoking at onset of treatment was associated with shorter survival (HR 1.56, 95% CI, 1.22-1.98, p < 0.001). Ever smokers had shorter survival than never smokers (HR 1.80, 95% CI, 1.25-2.59, p = 0.001). On multivariate analysis, with stage, PS, albumin, and gender as covariates, both smoking at start of chemotherapy and CRP elevation were independent negative prognostic factors for survival. CONCLUSIONS: CRP and smoking status are independent prognostic factors for survival in patients with advanced NSCLC receiving palliative first-line chemotherapy and provide additional information to established prognostic factors such as stage of disease and performance status.
