Abstract

BACKGROUND: Breast cancer is the most common malignancy in women and leads to substantial health issues
globally. Historically, Modified Radical Mastectomy (MRM) total removal of breast and tissue was a standard
treatment of choice. However, advances in surgical techniques as well as oncological care has led way for Breast
Conservation Surgery (BCS), where the tumor is removed, while preserving the breast's appearance. While the
intent of both approaches is to provide an adequate oncological control, the perioperative outcomes, complication
rates and the resulting patient quality of life have been a matter of ongoing debate when discussing comparative
efficacy and aesthetic outcome. Objective: To compare the outcome of two different surgical methods, Modified
Radical Mastectomy (MRM) and Breast Conservation Surgery (BCS), in treatment of breast cancer.
MATERIALS And Methods: This comparative observational study was carried out at General Surgery
Department Hayatabad Medical Complex Peshawar during the period (August 2020 to October 2021). A total of
120 female patients suffering from breast cancer were enrolled. A total of 57(47.5%) patients underwent
MRM(Group A) whereas 63(52.5%) further received BCS for tumor excision while maintaining breast appearance
(Group B). RESULTS: Axillary lymph node metastasis was present in 19(33.3%) cases in group A and 22(34.9%)
cases in group B. In group A there were 34(59.6%) cases of TNM stage-1 and 23(40.4%) cases had stage-II, while
in group B stage-I was noted in 41(65%) cases and stage-II in 22(35%) cases respectively. In group A invasive
ductal carcinoma was observed in 42(73.6%) cases, invasive lobular carcinoma in 10(21.3%) and other types were
5(8.8%), while on the other hand in group B these figures were 46(73%), 12(19%) and 5(7.9%) respectively. There
was no significant difference in age, menopause status and other general data, suggesting that the two groups were
comparable (P>0.05). CONCLUSION: BCs provides better perioperative outcomes, lesser postoperative
complications and aesthetic superiority than MRM in breast cancer patients.
