ACGME 2011 duty-hour guidelines: consequences expected by radiology residency directors and chief residents.

PURPOSE: The aim of this study was to assess perceptions of the 2011 ACGME duty-hour guidelines among radiology residency directors and chief residents with regard to resident training, the practice of radiology, the quality of resident life, and faculty and staff costs. METHODS: An online survey was sent to radiology program directors and chief residents via the Association of University Radiologists. RESULTS: The response rates were 36.7% for program directors and 18.6% for chief residents. Responses were generally weakly negative from both radiology program directors and chief residents. CONCLUSIONS: Both radiology program directors and chief residents have negative perceptions of the effect of the 2011 ACGME duty-hour guidelines on radiology residency programs. There was significant disagreement between program directors and chief residents with regard to whether attending radiologists or residents would be more affected by the new guidelines.

Impact of MRI-evaluated neoadjuvant chemotherapy response on change of surgical recommendation in breast cancer.

OBJECTIVE: To investigate how MRI imaging of neoadjuvant chemotherapy (NAC) tumor response affects the recommendation for optimal breast cancer surgery, both before and after NAC. SUMMARY BACKGROUND DATA: Understanding how imaging findings are incorporated into surgeons' decision-making processes will help establish appropriate imaging guidelines for recommending breast conservation surgery (BCS) after the NAC. METHODS: Seventy-six breast cancer patients undergoing NAC with MRI follow-up studies were analyzed. Two experienced breast surgeons reviewed all cases. An initial surgical recommendation was made based on the pre-NAC lesion presentation; a subsequent surgical recommendation was made based on the post-NAC tumor response. Finally, the pathology results were disclosed and the surgeons were asked to decide on the optimal definitive surgical procedure. MRI findings throughout the entire course of the NAC were analyzed to understand how they affected different recommendations. RESULTS: Before the NAC, a large tumor size or extent of disease were the primary determinant factors for mastectomy. In this study, the mean tumor size was 5.3 +/- 3.4 cm (RECIST) in the mastectomy group and 3.2 +/- 1.6 cm in the lumpectomy group (P = 0.0001). After the NAC, based on consensus recommendations, 21 mastectomy candidates remained for mastectomy, with tumor size decreasing from 7.4 +/- 4.5 to 1.5 +/- 2.5 cm, and 22 mastectomy candidates were changed to lumpectomy, with tumor size decreasing from 4.2 +/- 2.1 to 0.4 +/- 0.6 cm. When the final pathology revealed pCR or minimal residual disease, the surgeons agreed that BCS is the optimal procedure. On the other hand, for a large extent of residual disease, mastectomy should be performed. CONCLUSION: In patients who had more extensive pretreatment disease, despite an excellent response to NAC, the surgeons still tended to apply an aggressive approach and recommended mastectomy. Given that the confirmation of pCR or minimal residual disease would change surgeons' recommendations for less aggressive, conservation surgery, the maturity of MRI for NAC response prediction may provide reliable staging information to aid in the recommendation of the optimal surgical procedure.
