Background: Neoadjuvant therapy (NT) is increasingly utilized for patients with pancreatic ductal adenocarcinoma (PDAC). Disease progression, toxicity, and failure to undergo surgical resection are common during NT, yet little research has focused on efforts to optimize care delivery. We sought to define and validate a novel composite outcomes metric that characterizes the successful delivery of NT.

Background: Although resection is generally necessary for curative-intent treatment of most solid organ cancers, surgery is occasionally aborted due to intraoperative findings. Following aborted cancer surgery, patients have unique care needs that specialized palliative care (PC) providers may be best equipped to manage. We hypothesized that early ambulatory PC referral following aborted cancer surgery would be feasible and acceptable.

Article Synopsis
  • Patients with locally advanced rectal cancer (LARC) who undergo incomplete total mesorectal excision (TME) generally have poorer cancer outcomes, and the link between TME quality, adjuvant chemotherapy, and these outcomes has been under-researched.
  • A study analyzed 746 LARC patients treated with neoadjuvant chemoradiation or short-course radiotherapy followed by surgery and found that adjuvant chemotherapy significantly reduced mortality risk for all patients and decreased locoregional recurrence specifically in those with complete TME.
  • The results indicate that adjuvant chemotherapy could improve oncologic outcomes for LARC patients undergoing surgery after neoadjuvant treatments, highlighting its potential benefits in clinical management.

Introduction: Locoregional therapies are a mainstay of treatment for patients with neuroendocrine liver metastases (NELM), yet the optimal transarterial approach remains undefined and recent studies have raised concern over the safety of transarterial chemoembolization (TACE).

Methods: Patients with NELM who underwent TACE or transarterial embolization (TAE) at a single institution between 2000-2022 were retrospectively reviewed. Propensity score matching (PSM) controlling for age, sex, bilateral disease, tumor size, lobar embolization, grade, and extrahepatic disease was utilized to compare short- and long-term outcomes.

Background: Despite calls for regionalizing pancreatic cancer (PC) care to high-volume centers (HVCs), many patients with PC elect to receive therapy closer to their home or at multiple institutions. In the context of cross-institutional PC care, the challenges associated with coordinating care are poorly understood.

Methods: In this qualitative study we conducted semi-structured interviews with oncology clinicians from a HVC (n = 9) and community-based hospitals (n = 11) to assess their perspectives related to coordinating the care of and treating PC patients across their respective institutions.

Neoadjuvant therapy (NAT) for early-stage pancreatic ductal adenocarcinoma (PDA) has recently gained prominence. We investigated the clinical significance of mucin 5 AC (MUC5AC), which exists in two major glycoforms, a less-glycosylated immature isoform (IM) and a heavily glycosylated mature isoform (MM), as a biomarker in resected PDA. Immunohistochemistry was performed on 100 resected PDAs to evaluate the expression of the IM and MM of MUC5AC using their respective monoclonal antibodies, CLH2 (NBP2-44455) and 45M1 (ab3649).

Article Synopsis
  • - The study investigates long-term outcomes for patients with very-low rectal cancer who underwent either abdominoperineal resection (APR) or low anterior resection (LAR), focusing on disease-free survival and other key factors.
  • - Analysis of data from the United States Rectal Cancer Consortium included 431 patients, revealing no significant differences in disease-free survival, overall survival, complications, or hospital stay length between the two surgical methods.
  • - The findings suggest that both APR and LAR are valid treatment options for very-low rectal cancer without sphincter involvement, as neither approach showed a clear advantage in patient outcomes.

Introduction: Despite being a key metric with a significant correlation with the outcomes of patients with rectal cancer, the optimal surgical approach for total mesorectal excision (TME) has not yet been identified. The aim of this study was to assess the association of the surgical approach on the quality of TME and surgical margins and to characterize the surgical and long-term oncologic outcomes in patients undergoing robotic, laparoscopic, and open TME for rectal cancer.

Methods: Patients with primary, nonmetastatic rectal adenocarcinoma who underwent either lower anterior resection or abdominoperineal resection via robotic (Rob), laparoscopic (Lap), or open approaches were selected from the US Rectal Cancer Consortium database (2007-2017).
