Assessment of Cosmetic Outcome of Oncoplastic Breast Conservation Surgery in Women with Early Breast Cancer: a Prospective Cohort Study

Background: The aim of this study was to assess the cosmetic outcome of patients undergoing oncoplastic breast conserving surgery in Indian population.

Materials And Methods: A prospective cohort of 35 patients who were eligible for breast conservation surgery was included in the study from year 2007 to 2009. Patients with central quadrant tumors were excluded from the study. A double - blind cosmetic assessment was done by a plastic surgeon and a senior nurse not involved in the management of patients. Moreover, self-assessment was carried out by the patient regarding the satisfaction of surgery, comfort with brasserie, social and sexual life after oncoplastic surgery.

Results: In this study, 35 patients underwent oncoplastic breast conservation surgery by various techniques. The cosmetic outcome scores of the surgeon and nurse were analyzed for inter rater agreement using inter-class Correlation Coefficients. There was a good association between them. The risk factors for poor cosmetic outcome was studied by univariate analysis and significant correlation was obtained with age, volume of breast tissue excised and estimated percentage of breast volume excised (P < 0.05). Moreover, 96% of patients were moderately to extremely satisfied with the surgery. Patients were offered an option for cosmetic correction of contralateral breast by mastopexy or reduction mammoplasty however, none of them agreed for another procedure.

Conclusions: Oncoplastic breast surgery helps to resect larger volume of tissue with wider margins around the tumor. It helps to achieve better cosmesis and extends the indications for breast conservation. Most of the patients were satisfied with mere preservation of the breast mound rather than a symmetrical contralateral breast.
