Background: Despite numerous studies of partial mastectomy and psychologic morbidity in the first 24 months following surgery, little is known about the long term psychosocial repercussions of partial and total mastectomy.
Methods: The effect of the type of mastectomy on psychologic adjustment was assessed among 124 breast carcinoma survivors, 47 of whom underwent partial mastectomy and 77 of whom underwent total mastectomy, 8 years after initial treatment. Interviews were also conducted 3 and 18 months after surgery. Psychologic distress was assessed using the Psychiatric Symptom Index. Other outcomes included physical symptoms, patients' perceptions of their own health, satisfaction with the type of surgery performed and with the appearance of the scar, and marital and sexual adjustments.
Results: No statistically significant differences between partial and total mastectomy were observed with respect to long term quality of life. Age at diagnosis modified the relation between the type of mastectomy and psychologic distress in both the short term and the long term (P = 0.04). Among women younger than 50 years, partial mastectomy appeared to be protective against distress when compared with total mastectomy. In contrast, among women age 50 years or older, partial mastectomy was associated with higher psychologic distress levels at all interviews.
Conclusions: Assessed globally, partial and total mastectomy appear to be equivalent treatments in terms of patients' long term quality of life. However, both short term and long term distress levels after partial and total mastectomy may depend on patients' age at diagnosis. The findings of this study suggest that the increased use of partial mastectomy may lessen the negative effects of breast carcinoma on younger survivors' quality of life. Nevertheless, total mastectomy may be an appropriate initial treatment for some women who truly choose it.
