Department of Surgery and Science, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan.

The interim analysis of the CIRCULATE-Japan GALAXY observational study demonstrated the association of circulating tumor DNA (ctDNA)-based molecular residual disease (MRD) detection with recurrence risk and benefit from adjuvant chemotherapy (ACT) in resectable colorectal cancer (CRC). This updated analysis with a 23-month median follow-up, including 2,240 patients with stage II-III colon cancer or stage IV CRC, reinforces the prognostic value of ctDNA positivity during the MRD window with significantly inferior disease-free survival (DFS; hazard ratio (HR): 11.99, P < 0.

Article Synopsis
  • Previous studies found that gemcitabine (GEM) chemotherapy increases GFPT2 expression in pancreatic cancer cells, linking it to metastasis.
  • * GFPT2 influences the hexosamine biosynthesis pathway (HBP), which plays a role in enhancing the metastatic potential of these cancer cells.
  • * The study confirmed that increased GFPT2 expression from GEM exposure is associated with greater cancer cell migration, invasion, and a higher risk of liver metastasis post-chemotherapy, highlighting potential therapeutic targets for preventing metastasis.

Purpose: Sarcopenia influences the short- and long-term outcomes of various medical conditions including malignancy. Ishii's screening test estimates the probability of sarcopenia based on a score calculated by three simple variables: age, grip strength, and calf circumference. We investigated the clinical significance of Ishii's score for patients with non-metastatic obstructive colorectal cancer (OCRC) who underwent curative surgery after intraluminal decompression.

Article Synopsis
  • The study evaluated the effectiveness of preoperative pancreatic juice cytology (PJC) in diagnosing intraductal papillary mucinous neoplasm (IPMN) of the pancreas to inform treatment strategies.
  • Out of 1,130 patients, 852 underwent PJC, showing an overall accuracy of 55% for distinguishing cancerous from noncancerous lesions, with varying rates based on IPMN type.
  • Despite low sensitivity, the high positive predictive value suggests PJC may still be useful in uncertain surgical cases but is generally not recommended as a reliable diagnostic tool.

Background: Chemotherapy in combination with anti-epidermal growth factor receptor (EGFR) antibody is considered a first-line treatment regimen for RAS wild-type and left-sided metastatic colorectal cancer (mCRC), whereas second-line treatment regimens have not yet been established. Few studies have prospectively evaluated second-line treatment with anti-vascular endothelial growth factor antibody after first-line anti-EGFR antibody therapy for RAS wild-type mCRC.

Patients And Methods: This non-randomized phase II trial investigated the clinical outcomes of second-line ramucirumab (RAM) plus fluorouracil, levofolinate, and irinotecan (FOLFIRI) after first-line anti-EGFR antibody in combination with doublet or triplet regimen in patients with RAS wild-type mCRC.

Background/objectives: The detection of malignancy is a major concern in the management of intraductal papillary mucinous neoplasm (IPMN). The height of the mural nodule (MN), estimated using endoscopic ultrasound (EUS) and computed tomography (CT), has been considered crucial for predicting malignant IPMN. Currently, whether surveillance using CT or EUS alone is sufficient for detecting MNs remains unclear.

Article Synopsis
  • Despite standard treatments, over 30% of colorectal cancer patients experience relapse after surgery.
  • The GALAXY study analyzed presurgical and postsurgical circulating tumor DNA (ctDNA) in 1,039 patients with stage II-IV resectable colorectal cancer and found that postsurgical ctDNA positivity significantly correlates with higher recurrence risk.
  • The findings suggest that ctDNA testing could help identify patients who may benefit from adjuvant chemotherapy after surgery, particularly those with stage II or III disease.
