Choosing Mastectomy vs. Lumpectomy-With-Radiation: Experiences of Breast Cancer Survivors.

Background Annually about 280,000 women are diagnosed with breast cancer. Treatment options depend on age, comorbidities, tumor stage, grade, size, and other factors. Often, patients must decide between two surgical treatment options: mastectomy or lumpectomy-with-radiation herein simply called a lumpectomy. Since both offer similar survival outcomes, the choice ultimately is the patient's. However, most rely on inputs from doctors, family, friends, personal research, and other actions. We believe decision-making processes for future patients will be aided if experiences of prior breast cancer survivors are known. This study's aim is to provide such information. Methods Feedback from prior breast cancer survivors was obtained using a 19-question survey distributed online to multiple breast cancer support groups. It focused on issues relevant to choosing between the two surgical options including, post-surgical complications, breast reconstruction, chronic pain, cosmetics, and surgery-choice satisfaction. Results Respondents (N=1606) had a median age of 49 years (range 26 to 88 years) and had a median body mass index (BMI) of 26.6 Kg/m. There were 978 mastectomy patients (60.9%) and 628 lumpectomy patients (39.1%). With regard to post-surgical reconstruction, 64.2% of mastectomy respondents and 13.5% of lumpectomy respondents decided to undergo breast cancer reconstruction following breast cancer surgery. Almost all (99.8%) of lumpectomy respondents had radiation side-effects; with skin irritation and thickening and chest wall tenderness being the most common. Among mastectomy patients, 94.3% had one or more complications; loss-or-changes in nipple or breast sensation, uneven breasts, chest wall tenderness, and breast swelling were the most common complications. Post-surgical pain lasting six months or more was experienced by a smaller percentage of mastectomy vs. lumpectomy patients (64.1% vs. 78%, p <0.00001). Mastectomy patients were also less likely to have pain that was persistent and present up to the time of the survey (35.4% vs. 46.0%, p=0.0002). With respect to cosmetic outcomes, mastectomy patients vs. lumpectomy patients were less likely to be either satisfied or very satisfied (52.2% vs. 62.7%, p=0.00004). Overall satisfaction of surgical treatment was 70.9% for mastectomy patients and 68.6% for lumpectomy patients. Conclusion Based on the experiences of these breast cancer survivors, mastectomy is associated with less chronic pain frequency and lower incidence of post-surgical side effects compared to lumpectomy. However, mastectomy is associated with lower cosmetic satisfaction. Breast cancer survivors that underwent a lumpectomy, reported being more satisfied with cosmetic outcomes but almost all reported radiation side-effects with skin thickening listed as the most common. Lumpectomy was also associated with higher chronic pain frequency compared to mastectomy. The overall surgical treatment satisfaction reported by mastectomy and lumpectomy respondents was similar. The composite findings will provide information that will aid future breast cancer patients in making a decision between having a mastectomy or a lumpectomy.
