Effect of glucocorticoid use on survival in patients with stage I-III breast cancer

Abstract

Glucocorticoids (GCs) are commonly used in breast cancer patients to ameliorate emesis induced by chemotherapy. Some preclinical studies have suggested that systemic GCs might promote survival of estrogen receptor (ER)-negative breast cancer cells. This study aims to clarify their clinical effect on patient survival. A total of 18,596 women with newly diagnosed stage I-III breast cancer in 2002-2006 were identified from the Taiwan Cancer Database and drug treatment was examined from the Taiwan National Health Insurance Claims Database. Of these, 3989 who did not receive adjuvant chemotherapy (non-chemotherapy cohort) and 3237 patients who received six cycles of adjuvant anthracycline-based chemotherapy (anthracycline cohort) were included. The impact of GC use on survival was analyzed separately in these two cohorts using Cox proportional hazards models. In the non-chemotherapy cohort, GC use was associated with aggressive clinicopathological features of breast cancer. High-dose GC was associated with shorter overall survival in univariate analysis but not in multivariate analysis. In the anthracycline cohort, multivariate analysis showed that GC use at each dose level was significantly associated with longer breast cancer-spec...Continue Reading

Breast Cancer: Chemo-Resistance

Some cancers are difficult to treat and aggressive including the "triple-negative" breast cancer. This type of cancer is chemoresistant even before chemotherapy begins. Here are the latest discoveries chemo-resistance in breast cancer.
