How Effective is the Treatment of Locally Advanced and Metastatic Breast Cancer in Developing Centres?: A Retrospective Review

Abstract

BACKGROUND: The use of chemotherapy in advanced metastatic breast cancer remains a subject of controversy. The thought of MicKinnon et al (early 1950s) that the course of breast cancer was unaffected by chemotherapy has been refuted by results of treatment in the developed countries. The poor result of treatment in developing centres still compares with prechemotherapy era. Consequently, The McKinnon’s thought may still lurk. We compared the survival of chemotherapy treated with chemotherapy untreated cancer of breast patients. METHOD: Records of breast cancer patients who presented and died between January 2010 and May 2014 were reviewed. The primary outcome was overall survival. Records of patients that received chemotherapy with or without other tumor directed specific therapy were compared with records of patients who did not receive any tumor directed therapy. RESULT: Thirty-one patients received chemotherapy while 25 patients did not. All were females, more than 90% were of the patients had advanced or metastatic disease. Treatments were not biologically directed and treatment plans were largely compromised and suboptimal. The overall mean survival was 19.2 ±9.2 months, and the median duration was 17.5 months(range 6-44months). The overall survival was not statistically different between the two groups (p= 0.230, unequal variance assumed). The objective of using neoadjuvant chemotherapy for fungating lesions was not achieved. CONCLUSION: In advanced and metastatic breast cancer, outcomes of patients who receive suboptimal regimen of cytotoxic chemotherapy do not differ from chemotherapy untreated patients.
