Breast magnetic resonance imaging (MRI) is increasingly used for breast cancer treatment planning. The aim of this study was to evaluate rates of mastectomy and breast-conserving surgery (BCS) in patients who undergo preoperative MRI. ⋯ Preoperative MRI was associated with higher rates of mastectomy and detection of occult contralateral breast cancer, but was not associated with lower reexcision rates.

Consensus guidelines recommend neoadjuvant therapy in locally advanced esophageal cancer; however, whether this recommendation has been widely adopted is unknown. Therefore, we evaluated the utilization of neoadjuvant therapy in esophageal cancer and its association with outcomes in the United States. ⋯ In surgically treated patients, the use of neoadjuvant trimodal therapy has increased in the past decade; however, opportunities exist to improve adherence to national guidelines.

Multiorgan resection for cancer is considered a demanding laparoscopic procedure. We report a laparoscopic radical nephrectomy and distal splenopancreatectomy for a locally advanced kidney tumor. ⋯ Oncologic rules of an "en bloc" resection can be respected also with a laparoscopic approach.

Robotic coloanal anastomosis with or without intersphincteric resection for low rectal cancer: starting with the perianal approach followed by robotic procedure.
Coloanal anastomosis (CAA)/intersphincteric resection (ISR) is a promising method of sphincter-preserving surgery for very low rectal cancer. Recently, a robotic system has been attempted in CAA/ISR. By means of a robotic system, an excellent stereoscopic view may be obtained with high illumination, and adequate traction and countertraction can be easily performed in a narrow pelvis using the Endowrist function. During robotic CAA/ISR, although the robotic system is necessary to perform pelvic dissection that comes before the perianal approach, the huge robotic arms located in the low abdominal region could interfere with comfortable perianal dissection for the surgeon. Therefore, the robotic system has to be withdrawn and then set up again above the patient's abdomen, which is time-consuming. Moreover, this process also makes it difficult to maintain the aseptic circumstance of the robotic system. To address this problem, it is necessary to change the sequence of the procedure. ⋯ Robotic CAA/ISR can be performed with good technical efficiency and acceptable morbidity. Further randomized, controlled studies assessing long-term survival, pelvic autonomic nerve function, and bowel function are needed before robotic CAA/ISR becomes widely accepted. Changing the sequence of the procedure, and thus performing the perianal approach before robotic dissection, may be a feasible method to avoid interference of the robotic system in the surgeon's moves using nonrobotic instruments while performing robotic CAA/ISR.

Recent results from the ACOSOG Z0011 trial question the use of intraoperative frozen section (FS) during sentinel lymph node (SLN) biopsy and the role of axillary dissection (ALND) for SLN-positive breast cancer patients. Here we present a 10-year trend analysis of SLN-FS and ALND in our practice. ⋯ Over 10 years, we have observed a diminishing rate of SLN-FS and, for patients with low-volume SLN metastases, fewer ALND, trends that suggest a more nuanced approach to axillary management. If the Z0011 selection criteria had been applied to our cohort, 66% of SLN-FS (4159 of 6327) and 48% of ALND (939 of 1953) would have been avoided, sparing 13% of all patients the morbidity of ALND.
