RESUMO
PURPOSE: To determine the long-term complication rates and cosmetic results for patients undergoing postmastectomy radiation therapy (PMRT) after immediate reconstruction (IR). METHODS AND MATERIALS: Between January 1998 and December 2005, 92 patients underwent modified radical mastectomy, IR, and PMRT in our practice. A total of 69 patients underwent tissue expander and implant reconstruction (TE/I), and 23 underwent autologous tissue reconstruction (ATR). Follow-up regarding complications and cosmesis was obtained for all 92 patients. Complications were scored as follows: Grade 1, no discomfort; Grade 2, discomfort affecting activities of daily living; Grade 3, surgical intervention or intravenous antibiotics required; and Grade 4, removal or replacement of the reconstruction. Cosmesis was rated as either acceptable or unacceptable to the patient. Both complications and cosmesis were correlated with treatment- and patient-related factors. RESULTS: Median follow-up for all patients was 38 months. The overall rate of severe complications (Grade 3-4) was 25%. The overall rate of poor functional results (Grade 2-4) was 43.4%. When analyzed as a function of type of reconstruction, the rate of Grade 3 to 4 complications was 33.3% for TE/I vs. 0% for ATR (p = 0.001). The rate of Grade 2 to 4 complications was 55% for TE/I vs. 8.7% for ATR (p < 0.001). Acceptable cosmesis was reported in 51% of TE/I patients vs. 82.6% of ATR patients (p = 0.007). No other treatment or patient-related factors had a significant impact on either complications or cosmesis. CONCLUSION: In patients undergoing PMRT after IR, ATR is associated with fewer long-term complications and better cosmetic results than TE/I.
