The management of patients with simultaneously diagnosed colorectal liver and lung metastases (SLLM) remains controversial. A recent study based on an analysis of the LiverMetSurvey demonstrated that patients with SLLM suitable for resection of all metastases have a survival similar to that of patients who undergo removal of isolated liver metastases.1 Simultaneous transdiaphragmatic resection of peripheral lung lesions and liver resection by laparotomy has been described previously.2 To the authors' knowledge, no previous reports on a similar minimally invasive approach have been published. In April 2015, the authors started performing combined minimally invasive transdiaphragmatic resections of peripheral colorectal lung metastases in patients undergoing laparoscopic liver resections. This video aims to demonstrate the authors' first experience with this minimally invasive approach. ⋯ Simultaneous transdiaphragmatic resection of peripheral lung lesions is feasible for patients undergoing laparoscopic liver resection. The low invasiveness of the described technique could facilitate an aggressive operative approach to SLLM.

Little is known about between-hospital differences in the rate of suboptimal lymphadenectomy. This study characterizes variation in hospital-specific rates of suboptimal lymphadenectomy and its effect on overall survival in a national hospital-based registry. ⋯ Large differences in hospital-specific rates of suboptimal lymphadenectomy were observed, and this variation was associated with survival. Quality improvement initiatives targeting hospital-level adherence to the national standard may improve overall survival among resected colon cancer patients.

Appendiceal cancer most commonly metastasizes to the peritoneum. Cytoreductive surgery (CRS) with heated intraperitoneal chemotherapy (HIPEC) is the standard of care for appendiceal cancer with peritoneal metastases. Adverse events postoperatively have been associated with reduced survival. We analyzed clinical outcomes, including complications after CRS and HIPEC in patients with appendiceal cancer, in a recent cohort of patients to identify prognostic factors. ⋯ CRS with HIPEC can achieve long-term survival for patients with appendix cancer with peritoneal metastases. Histologic subtype, lymph node metastasis, and incomplete cytoreduction are the significant predictors of OS. Postoperative adverse events had no impact on survival.

The purpose of this retrospective, population-based, cohort study was to identify patient and tumor characteristics that are associated with a high risk of tumor-positive margins after breast-conserving surgery (BCS) to optimize preoperative counseling. ⋯ Several clinicopathologic features are associated with involved resection margins after BCS for IBC. Assessment of these features preoperatively could be used to optimize preoperative counseling.

In patients undergoing two-stage hepatectomy (TSH) for colorectal liver metastases (CRLM), chemotherapy is discontinued before portal vein occlusion and restarted after curative resection. Long chemotherapy-free intervals (CFI) may lead to tumor progression and poor oncological outcomes. ⋯ A short CFI is associated with improved oncological outcome in patients undergoing TSH for CRLM. Decreased interstage intervals after ALPPS may facilitate the timely resumption of chemotherapy.
