Although the small intestine constitutes over 75% of the length and 90% of the mucosal surface of the gastrointestinal tract, small intestine cancer is rare and accounts for only 1% of gastrointestinal malignancies. Adenocarcinoma together with carcinoid tumours are the most common histological types of primary malignant tumours of the small bowel but others, including lymphoma and leiomyosarcoma, may less frequently be encountered. Adenocarcinomas are predominantly located in the duodenum. Primary adenocarcinoma of the duodenum is a rare malignant tumor, accounting for 0.3-0.5% of all gastroenteral malignancies. The diagnosis of primary adenocarcinoma of duodenum is often delayed because its symptoms and signs are nonspecific. In this work we want to focus on the diagnostic and therapeutic problems of duodenal adenocarcinoma, reporting a case report.

Adjuvant Chemotherapy After Resection of Localized Pancreatic Adenocarcinoma Following Preoperative FOLFIRINOX.
JAMA Oncol
January 2025
Amsterdam UMC, location University of Amsterdam, Department of Surgery, Amsterdam, the Netherlands.
Importance: The effect of adjuvant chemotherapy following resection of pancreatic adenocarcinoma after preoperative (m)FOLFIRINOX (combination leucovorin calcium [folinic acid], fluorouracil, irinotecan hydrochloride, and oxaliplatin in full or modified dosing) chemotherapy on overall survival (OS) is unclear because current studies do not account for the number of cycles of preoperative chemotherapy and adjuvant chemotherapy regimen.
Objective: To investigate the association of adjuvant chemotherapy following resection of pancreatic adenocarcinoma after preoperative (m)FOLFIRINOX with OS, taking into account the number of cycles of preoperative chemotherapy and adjuvant chemotherapy regimen.
Design, Setting, And Participants: This retrospective cohort study included patients with localized pancreatic adenocarcinoma treated with 2 to 11 cycles of preoperative (m)FOLFIRINOX followed by resection across 48 centers in 20 countries from 2010 to 2018.
Pembrolizumab ± paricalcitol in metastatic pancreatic cancer postmaximal cytoreduction.
Oncologist
January 2025
HonorHealth Research Institute, Scottsdale, AZ, United States.
Lessons Learned: Intravenous paricalcitol did not improve the efficacy of pembrolizumab, likely related to the short half-life.
Background: Immunotherapy has limited benefit in the treatment of advanced pancreatic cancer with the tumor microenvironment playing a key role in immune resistance. In preclinical studies, vitamin D receptor (VDR) agonists have been shown to sensitize pancreatic tumors to PD-1 blockade.
Ovarian clear cell carcinoma: open questions on the management and treatment algorithm.

Léon Bérard Cancer Center, Department of Surgical and Medical Oncology-Lyon, Université Claude Bernard Lyon 1, Lyon, France.
Ovarian clear cell carcinoma (OCCC) accounts for ~10% of all epithelial ovarian cancers and is considered a different entity from the more common high-grade serous ovarian carcinoma (HGSC), with distinct clinical presentations, different risk, and prognostic factors, and specific molecular features. Most OCCCs are diagnosed at an early stage and show favorable outcomes, in contrast to those diagnosed at advanced stages, which exhibit intrinsic resistance to platinum-based chemotherapy regimens and a very poor prognosis. The standard treatment of advanced OCCC is currently based on primary debulking surgery followed by platinum-based chemotherapy according to recent international guidelines.

Cancer Med
January 2025
Division of Gastroenterology and Nephrology, Department of Multidisciplinary Internal Medicine, Faculty of Medicine, Tottori University, Yonago, Japan.
Background And Aim: In recent years, there has been a rise in cryptogenic hepatocellular carcinoma (c-HCC) cases in Japan, posing a detection challenge due to an unknown etiology. This study aims to enhance diagnostic strategies for c-HCC by analyzing its characteristics and exploring current opportunities for detection.
Methods: A retrospective study was conducted from April 2012 to March 2022, enrolling 372 newly diagnosed hepatocellular carcinoma (HCC) patients.
Infiltrating T lymphocytes and tumor microenvironment within cholangiocarcinoma: immune heterogeneity, intercellular communication, immune checkpoints.
Front Immunol

Third Hospital of Shanxi Medical University, Shanxi Bethune Hospital, Shanxi Academy of Medical Sciences, Tongji Shanxi Hospital, Taiyuan, China.
Cholangiocarcinoma is the second most common primary liver cancer, and its global incidence has increased in recent years. Radical surgical resection and systemic chemotherapy have traditionally been the standard treatment options. However, the complexity of cholangiocarcinoma subtypes often presents a challenge for early diagnosis.
