The Prodige-7 trial has questioned the role of hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of peritoneal metastases from colorectal cancer (CRC-PM). ⋯ Our results confirmed that, in selected patients, perioperative s-CT and surgical treatment of CRC-PM resulted in unexpectedly high survival rates. Mitomycin C-based HIPEC did not increase morbidity but did not impact prognosis.

Appendiceal goblet cell adenocarcinoma (GCA) is often misclassified and mistreated due to mixed histologic features. In general, cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) is standard of care for peritoneal carcinomatosis (PC) from mucinous appendiceal tumors; however, in PC from GCA, data are limited and the role of CRS/HIPEC is controversial. We report outcomes in PC from appendiceal GCA treated with CRS/HIPEC. ⋯ CRS/HIPEC should be considered as the main treatment option for patients with PC from appendiceal GCA. When performed at a CRS/HIPEC specialty center, 5-year OS of 67% can be achieved.

Management of regional lymph nodes in patients with melanoma has evolved significantly in recent years. The value of nodal intervention, long utilized for its perceived therapeutic benefit, has now shifted to that of a critical prognostic procedure used to guide clinical decision making. This review focuses on the three landmark, randomized controlled trials evaluating the role of surgery for regional lymph nodes in melanoma: Multicenter Selective Lymphadenectomy Trial I (MSLT-I), German Dermatologic Cooperative Oncology Group-Selective Lymphadenectomy Trial (DeCOG-SLT), and Multicenter Selective Lymphadenectomy Trial II (MSLT-II).

The sentinel node biopsy following neoadjuvant chemotherapy (SN FNAC) study has shown that in node-positive (N+) breast cancer, sentinel node biopsy (SNB) can be performed following neoadjuvant chemotherapy (NAC), with a low false negative rate (FNR = 8.4%). A secondary endpoint of the SN FNAC study was to determine whether axillary ultrasound (AxUS) could predict axillary pathological complete response (ypN0) and increase the accuracy of SNB. ⋯ AxUS is not appropriate as a standalone staging procedure, and SNB itself is sufficient to assess the axilla post NAC in patients who present with N+ breast cancer.
