The perioperative coagulopathy, hemodynamic instability, and infectious complications that may occur during cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) has raised concerns about the safety of epidural analgesia in patients undergoing such procedures. ⋯ With close hematologic monitoring and particular attention to sterility, epidural analgesia can be safely provided to patients undergoing CRS with HIPEC. Early initiation of continuous epidural infusions during surgery could lead to decreased blood loss and less intraoperative fluid administration. Prospective randomized studies are required to further investigate these potential benefits.

For women with ductal carcinoma in situ (DCIS) undergoing breast-conserving surgery (BCS), the benefit of magnetic resonance imaging (MRI) remains unknown. Here we examine the relationship of MRI and locoregional recurrence (LRR) and contralateral breast cancer (CBC) for DCIS treated with BCS, with and without radiotherapy (RT). ⋯ We observed no association between perioperative MRI and lower LRR or CBC rates in patients with DCIS, with or without RT. In the absence of evidence that MRI improves outcomes, the routine perioperative use of MRI for DCIS should be questioned.

A complete surgical excision with negative tumor margins is the single most important factor in the prediction of long-term survival for most cancer patients with solid tumors. We hypothesized that image-guided surgery using nanoparticle-enhanced photoacoustic and fluorescence imaging could significantly reduce the rate of local recurrence. ⋯ These results suggest that photoacoustic and NIR intraoperative imaging can effectively assist a surgeon to locate primary tumors and to identify residual disease in real-time. This technology has promise to overcome current clinical challenges that result in the need for second surgical procedures.

Comparative Study
Radioactive iodine remnant uptake after completion thyroidectomy: not such a complete cancer operation.
Given limitations in preoperative diagnostics, thyroid lobectomy followed by completion thyroidectomy (CT) for differentiated thyroid cancer (DTC) may be required. It is unclear whether resection quality by CT differs from that by total thyroidectomy (TT). Additional surgeon or patient factors may also influence the "completeness" of resection. This study evaluated how CT and surgeon volume influence the adequacy of resection as measured by radioactive iodine (RAI) remnant uptake. ⋯ Single-stage TT provides a better resection based on smaller thyroid remnant uptakes than CT for patients with thyroid cancer. If a staged operation for cancer is necessary, surgeon volume may affect the completeness of resection.

Review Meta Analysis
Impact of preoperative diabetes on long-term survival after curative resection of pancreatic adenocarcinoma: a systematic review and meta-analysis.
Diabetes mellitus (DM) is coupled to the risk and symptomatic onset of pancreatic ductal adenocarcinoma (PDAC). The important question whether DM influences the prognosis of resected PDAC has not been systematically evaluated in the literature. We therefore performed a systematic review and meta-analysis evaluating the impact of preoperative DM on survival after curative surgery. ⋯ To our knowledge, this is the first meta-analysis evaluating long-term survival after PDAC resection in normoglycemic and diabetic patients, demonstrating a significantly worse outcome in the latter group. The mechanism behind this observation and the question whether different antidiabetic medications or early control of DM can improve survival in PDAC should be evaluated in further studies.
