As fluoroscopy-guided interventional procedures gain popularity, the associated health threats from radiation exposure to interventionalists during these procedures are increasing. Therefore, an understanding of the potential risks of radiation and careful consideration on minimizing exposure to radiation during the procedures are of paramount importance. The Korean Pancreatobiliary Association has developed a clinical practice guideline to minimize radiation exposure during fluoroscopy-guided interventional procedures.

Background: Approximately half of the patients with advanced pancreatic ductal adenocarcinoma (PDAC) receive subsequent lines of chemotherapy. Recently, the liposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (5-FU/LV) regimen is recommended as subsequent lines of chemotherapy. However, little is known about the predictive factors for the nal-IRI + 5-FU/LV regimen, especially in patients with previous irinotecan (IRI) exposure.

Context: Considering the absence of methods to find pancreatic cancer early, surveillance of high-risk groups is needed for early diagnosis.

Objective: The study aimed to investigate the effect in the incidence of pancreatic cancer and the differences between new-onset diabetes mellitus (NODM) and long-standing DM (LSDM) since NODM group is a representative high-risk group.

Methods: The Korean National Health Insurance Service-National Sample Cohort between 2002 and 2013 data were used.

FOLFIRINOX (oxaliplatin, leucovorin, irinotecan, and 5-fluorouracil) is a first-line chemotherapy for metastatic pancreatic cancer (PC). Chemotherapy-induced neutropenia is one of the most serious adverse events associated with advanced PC. Although polymorphisms are associated with the metabolism of irinotecan, their role as surrogate markers for FOLFIRINOX-induced neutropenia has not been confirmed.

Background: Approximately 80% of pancreatic ductal adenocarcinoma (PDAC) patients suffer from anorexia, weight loss, and asthenia. Most PDAC patients receive chemotherapy, which often worsens their nutritional status owing to the adverse effects of chemotherapy. Malnutrition of PDAC patients is known to be associated with poor prognosis; therefore, nutritional management during chemotherapy is a key factor influencing the outcome of the treatment.

Article Synopsis
  • The study investigates the effectiveness of neoadjuvant therapy followed by surgery in patients with resectable pancreatic ductal adenocarcinoma (PDAC), amidst ongoing debates regarding its benefits.
  • Out of 202 patients who underwent surgery with curative intent, those who received neoadjuvant therapy had smaller tumors, less lymphovascular invasion, and more negative resection margins than those who had surgery first.
  • After addressing selection bias, the neoadjuvant group showed significantly longer progression-free survival compared to the surgery-first group, although overall survival rates were similar in both groups, highlighting the need for future studies with larger and more consistent patient samples.

Purpose: FOLFIRINOX is the standard therapy in patients with unresectable pancreatic cancer (PC). However, FOLFIRINOX frequently induces febrile neutropenia (FN) and neutropenia. The purpose of this study was to explore risk factors for FN and grade 4 neutropenia (NP G4) in patients receiving FOLFIRINOX for PC.
