immediate breast reconstruction with prostheses after conservative treatment plus intraoperative radiotherapy long term esthetic and oncological outcomes

Abstract Electron intraoperative radiotherapy (ELIOT) has been introduced for breast conservative treatment (BCT) with promising oncological outcome. Thus, immediate breast reconstruction with prosthesis after BCT became possible due to minimal radiation effect on local tissue from ELIOT. We reported oncological and esthetical results of 29 BCT patients who had immediate implant reconstruction plus 21 Gy-ELIOT as the sole radiation treatment. All patients had prosthesis in ipsilateral breast and had simultaneous contralateral augmentation for symmetrical procedure. The average age was 52.3 years. There were stage Ia thirteen cases, stage Ib seven cases, stage IIa six cases and stage IIIb one case and two cases of intraepithelial neoplasia. From 54.2 (36–88) months follow up, the capsular contracture grading in the reconstructed breast from ELIOT-side is comparable with non-irradiated contralateral side. There was one patient who developed local recurrence (LR) and later on dead with breast related event (LR = 0.76% per year). There was no primary ipsilateral carcinomas and distant metastasis

positive axillary sentinel lymph node is axillary dissection always necessary

Summary There is considerable interest in foregoing axillary dissection (AD) when the sentinel node (SN) is positive in early breast cancer, particularly when axillary involvement is minimal (micrometastases or isolated tumor cells). In fact, clinical practice has run ahead of the evidence, since recent population-based data indicate that AD is 'underused' in breast cancer patients when the SN is positive. Several trials are addressing the problem (IBCSG 23-01, ASCOG Z0011, EORTC AMAROS). Only Z0011 has published interim results, finding, after a median follow-up of 6.3 years, no differences in locoregional recurrence or regional recurrence between patients, with a positive SN, who received AD vs. no further axillary treatment. Our own retrospective study evaluated patients with micrometastases or isolated tumor cells in the SN who received no further axillary treatment. We found high five-year survival and low cumulative incidence of axillary recurrence, supporting the findings of Z0011 and justifying the increasingly common practice of foregoing AD in women with minimal SN involvement. It is important to sound a note of caution however: If axillary dissection is not always necessary in women with a positive axilla, it seems important to be able to reliably identify the patients at high risk of developing overt axillary disease who should receive elective AD. Ancillary analyses of the IBCSG 23-01 and AMAROS trials, still in follow-up, may be able to do this
