Modified Radical Mastectomy vs Breast-Conserving Surgery: Current Clinical Practice in Women with Early Stage Breast Cancer at a Corporate Tertiary Cancer Center in India

Breast cancer is the most common cancer in women in urban India and surgery has one of the definitive roles in treating this cancer. Over the decades, multiple studies have been published and they have shown that BCS followed by radiotherapy has equivalent disease-free survival (DFS) and overall survival (OS) as compared with MRM. The surgeon has the main role in explaining the treatment options to the patient. It is a prospective study conducted at Vedant Cancer and Multispeciality Hospital in a metropolitan city, Thane, India. Patients with stage I or II breast cancer with tumor size less than 5 cm were included in the study. Patients with locally advanced and metastatic breast cancer were excluded from the study. The study population was early breast cancer patients registered and waiting for surgery (n = 86) at Vedant Cancer and Multispeciality Hospital from November 2019 to end of April 2020. The total number of females enrolled in the study were 86 and out of this, 79.1% (n = 68) females opted for MRM and 20.9% (n = 18) females opted for BCS in which 8 patients had changed their decision after re-counseling in the ward from MRM to BCS. The most common reasons selected by patients to undergo MRM were fear of cancer recurrence (30.2%, n = 26), avoidance of side effects of radiation therapy (25.5%, n = 22) and fear of radiation therapy (23.2%, n = 20). Surgeon had decided the surgical option in 79.1% (n = 68) cases. The study shows that the treating surgeon and patient's husband are the principal persons who decide the surgical option and active participation of women during counseling is an important factor.
