Adjuvant radiotherapy for node positive breast cancer postmastectomy has been recommended by two previously published randomized controlled trials (RCT). The local-regional recurrence rates in the control arms, however, were considered by some critics to be excessive (> 25% at 10 years). Inadequate surgery, as evidenced by the low number of axillary nodes reported, may have resulted in the high local-regional recurrence rates, allowing for the benefits seen with radiotherapy. Fellowship trained surgical oncologists might provide "better quality" surgery, resulting in lower recurrence rates and thus making adjuvant radiotherapy unnecessary. Our objective was to establish the local-regional control rate postmastectomy in node positive breast cancer patients operated on by surgical oncologists, and to determine if treatment recommendations from previous RCTs are generalizable. ⋯ Despite some evidence of "better quality" surgery, there was no clinically significant difference in the local-regional recurrence rate in this case series compared to controls in two previous RCTs. Recommendations for postmastectomy radiotherapy should be considered for node positive breast cancers, even if operated upon by surgical oncologists.
