| Summary: | <h4>Purpose</h4>Breast conserving surgery (BCS) has become the preferred surgical option for the management of patients with nonmetastatic breast cancer in high-income countries. However, little is known about the distribution and determinants of BCS in low-and middle-income countries, especially those with high HIV prevalence.<h4>Methods</h4>We compared demographic and clinical characteristics of female patients who received BCS and those who received total mastectomy (TM) for nonmetastatic invasive carcinoma of the breast in Soweto, South Africa, 2009-2011. We also developed a multivariable logistic regression model of predictors of type of surgery.<h4>Results</h4>Of 445 patients, 354 (80%) underwent TM and 91 (20%) BCS. Of 373 patients screened for HIV, 59 (15.8%) tested positive. Eighty-two of 294 patients with stage I/II disease (28%), but just 9 of 151 (6%) with stage III disease had BCS (p<0.001). All women who received BCS (except for seven who received completion mastectomy within 6 weeks of BCS) and 235 (66.4%) women who received TM were referred for radiation therapy (RT). In our multivariable analysis, age group 50-59 years (OR = 2.28, 95% CI = 1.1-4.8) and ≥70 years (OR = 9.55, 95% CI = 2.9-31.2) vs. age group <40 years, stage at diagnosis (stage II (OR = 3.79, 95% CI = 1.6-8.2) and stage III (OR = 27.8, 95% CI = 9.0-78.8) vs. stage 1, HIV (HIV positive (OR = 3.19, 95% CI = 1.3-7.9) vs. HIV negative) and HER2-enriched subtype (OR = 3.50, 95% CI = 1.2-10.1) vs. triple negative were independently associated with TM.<h4>Conclusion</h4>TM was more common than BCS among patients with nonmetastatic breast cancer in Soweto, not only among patients with locally advanced disease at diagnosis, but also among women with stage I and II disease. |
