Lumpectomy Versus Mastectomy in Breast Cancer: Comparison of Postoperative Consequences and Treatment Progress

Background: Lumpectomy and mastectomy remain the main surgical procedure of breast cancer as a part of treatment as well as management. This study was aimed to compare the early post-operative outcomes of lumpectomy (BCS) versus mastectomy (MRM). Methods: It was an observational study conducted at the Department of Surgical Oncology of National Institute of Cancer Research and Hospital (NICRH), Mohakhali, Dhaka, Bangladesh during the period from October 2016 to January 2019. The study sample consisted of 264 cancer patients who admitted in the hospital. The purposive sampling was done following inclusion criteria. Having collection of data, chi-square test was done to see the association of breast cancer among female patients. Results: Out of 264, 200 (75.75%) patients underwent mastectomy (MRM) and remaining percentage of patients underwent lumpectomy. The mean age of the patients was 37.69 (SD±10.31) and 44.82 (SD±7.65) in lumpectomy and mastectomy group respectively. Wound infection was present among 12.5% and 24% lumpectomy and mastectomy patients. Subsequently, seroma was present among 18.75% and 54% patients who underwent lumpectomy (BCS) and mastectomy (MRM) respectively which was statistically significant (P<0.014). Flap necrosis was found only among 16% mastectomy patients (P<0.04). There was significant difference in income and education among lumpectomy and mastectomy patients. However, the mean duration of hospital stay was 6.06±0.85 days and 17.70±4.70 days in lumpectomy (BCS) and mastectomy (MRM) group respectively which was statistically significant (P< 0.05). Conclusion: This study showed that lumpectomy (BCS) had early recovery and better post-operative treatment progress than mastectomy (MRM).
