Purpose: To develop and validate a nomogram for predicting the overall survival of patients with metastatic pancreatic cancer.
Methods: This retrospective study included 236 patients with metastatic pancreatic cancer treated at Guangxi Medical University Cancer Hospital between October 2013 and October 2022. Patients were grouped according to hepatitis B virus (HBV) infection status. Cox proportional hazard regression was used to identify the prognostic factors independently associated with overall survival. Results were used to build a nomogram, which was assessed through internal validation using bootstrap resampling.
Results: Patients in the HBV-positive group (N = 37) showed significantly better overall survival than those in the HBV-negative group (N=199; = 0.014). Overall survival was independently associated with the following factors: HBV infection status, sex, chemotherapy, metastatic sites, a combined index of hemoglobin, albumin, lymphocytes, and platelets, neutrophil-albumin ratio, as well as levels of CA125. The nomogram showed good predictive power, with an area under the curve of 0.808 for the time-dependent receiver operating characteristic. Calibration and decision curve analyses indicated good calibration and clinical usefulness of the nomogram for predicting the overall survival of patients with metastatic pancreatic cancer.
Conclusion: A nomogram based on the HBV infection status and inflammatory nutritional markers may help predict the overall survival of patients with metastatic pancreatic cancer and guide personalized clinical treatment.

Colorectal cancer (CRC) is widely recognized as the third most prevalent malignancy globally and the second leading cause of cancer-related mortality. Traditional treatment modalities for CRC, including surgery, chemotherapy, and radiotherapy, can be utilized either individually or in combination. However, these treatments frequently result in significant side effects due to their non-specificity and cytotoxicity affecting all cells.

Background Aims: The role of adjuvant transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) following curative resection remains controversial. We aimed to determine the effectiveness of postoperative adjuvant TACE in HCC patients.
Approach Results: In this randomized phase 3 trial, histologically confirmed HCC patients (AJCC TNM stage I and II) were randomly assigned (1:1) to adjuvant TACE or observation groups.

Background: Complex surgery during initial cancer treatment can limit surgical options when planning management of a secondary malignancy. Subtotal esophagectomy and pancreatoduodenectomy are the most invasive and difficult procedures in gastroenterological surgery. Surgical cases in which subtotal esophagectomy was performed after pancreatoduodenectomy with pancreaticogastrostomy are extremely rare and challenging procedures due to the resulting complicated anatomical changes.

Pancreatic ductal adenocarcinoma (PDAC) is a malignant cancer with a high mortality and limited treatment options. Systemic chemotherapy remains the only approach for improving survival in patients with unresectable locally advanced and/or metastatic disease which comprises most patients. Targeted therapies have so far been disappointing with limited applicability and improvement in overall survival.

Introduction: Nonfunctioning pancreatic neuroendocrine tumors (NF-PNETs) have been diagnosed increasingly often but still represent rare pancreatic neoplasms. Surgery is a potentially curative approach for patients with NF-PNETs. In recent years, minimally invasive surgery (MIS) has been applied more frequently for surgical resection of NF-PNETs.
