Multicenter Study Clinical Trial
The Role of Sentinel Lymph Node Biopsy and Factors Associated with Invasion in Extensive DCIS of the Breast Treated by Mastectomy: The Cinnamome Prospective Multicenter Study.
When invasive components are discovered at mastectomy for vacuum-assisted biopsy (VAB)-diagnosed ductal carcinoma in situ (DCIS), the only option available is axillary lymph node dissection (ALND). The primary aim of this prospective multicenter trial was to determine the benefit of performing upfront sentinel lymph node (SLN) biopsy for these patients. The secondary aim was to determine DCIS factors associated with microinvasion or invasion. ⋯ Underestimation of invasive components is high when DCIS is diagnosed by VAB in patients undergoing mastectomy. Upfront SLN for patients with VAB-diagnosed extensive DCIS avoids unnecessary ALND for two-thirds of patients with micro or invasive disease on mastectomy.

Randomized Controlled Trial Multicenter Study
Influence of Food Intake on the Healing Process of Postoperative Pancreatic Fistula After Pancreatoduodenectomy: A Multi-institutional Randomized Controlled Trial.
The usefulness of enteral nutrition via a nasointestinal tube for patients who develop postoperative pancreatic fistula (POPF) after miscellaneous pancreatectomy procedures has been reported. However, no clear evidence regarding whether oral intake is possible during management of POPF after pancreatoduodenectomy (PD) is currently available. We investigated the effects of oral food intake on the healing process of POPF after PD by a multi-institutional randomized controlled trial. ⋯ Food intake did not aggravate POPF and did not prolong the length of drain placement or hospital stay after PD. There may be no need to avoid oral dietary intake in patients with POPF.

Red blood cell transfusions (RBCTs) are associated with cancer recurrence following resection of colorectal cancer. Their impact after colorectal liver metastases (CRLM) resection remains debated. We sought to explore the association between perioperative RBCT and oncologic outcomes following resection of CRLM. ⋯ Perioperative RBCT is independently associated with decreased OS and RFS following hepatectomy for CRLM. Interventions to minimize and rationalize the use of RBCT for hepatectomy are warranted to mitigate this detrimental effect on long-term outcomes.

Colon cancer nomogram designed by Memorial Sloan-Kettering Cancer Center (MSKCC) is an online prediction tool to predict overall survival for individual patient after curative resection. However, this model was never externally validated. We evaluated the accuracy of this nomogram in an independent external Chinese cohort. ⋯ The MSKCC nomogram for colon cancer provides more accurate survival predictions than the AJCC staging system when applied to an external Chinese cohort. The MSKCC nomogram improved individualized prediction of survival and may aid in more accurate patient counseling, selection of various treatment options, and follow-up scheduling.

Sarcopenia is linked to poor outcomes after abdominal surgery. We hypothesized that radiographic sarcopenia metrics enhance prediction of complications after pancreaticoduodenectomy (PD) when combined with clinical and frailty data. ⋯ When combined with clinical and frailty assessments, radiographic sarcopenia metrics enhance prediction of post-PD outcomes.
