Abstract
Introduction
There is a paucity of literature comparing the postoperative outcomes of males and females with breast cancer who undergo mastectomy. The aim of this study is to evaluate the comorbidities and 30-day post-mastectomy complication rates among males and females.
Methods
We performed a retrospective analysis of breast cancer patients who underwent mastectomy from 2014 to 2016 using the American College of Surgeon's National Surgical Quality Improvement Project database. Data including patient demographics, comorbidities, and 30-day surgical and medical complications were collected. Statistical analysis included Chi-square and Fisher’s exact tests for categorical variables and Student T-tests for continuous variables. Statistical significance was defined as p < 0.05.
Results
A total of 15,167 patients were identified. There were 497 males (3.3%) and 14,670 females (96.7%). Age was significantly higher in females compared to males (63.5 vs. 57.6 years, p < 0.001). Body mass index (BMI) at time of surgery was also higher in males (30.0 vs. 29.3 kg/m2, p = 0.011). There was a higher prevalence of diabetes in males (20.1 vs. 16.5%, p = 0.032). Operative duration was significantly longer in females (114.9 vs. 95.0 min, p < 0.001). Median postoperative length of stay was also longer in females (1.2 vs. 0.8 days, p < 0.001). There were no significant differences in 30-day medical or surgical complication rates between the two sexes.
Conclusion
Our findings suggest that differences in age, BMI, and comorbidities between males and females do not significantly impact 30-day medical or surgical complications following total mastectomy for breast cancer. Further research is warranted to identify perioperative risk factors that influence post-mastectomy complication rates.
