PURPOSE: Cytokeratin 19 fragment 21-1 (CYFRA 21-1) and cytokeratin 19 fragment 2G2 (CK 19-2G2) are two soluble fragments of cytokeratin 19 (CK 19) that can be detected in serum. CK 19-positive hepatocellular carcinoma (HCC) is characterized by an aggressive behavior and a poor outcome. This study aimed to assess the prognostic value of serum CYFRA 21-1 and CK 19-2G2 in predicting tumor aggressiveness and overall survival (OS) in patients with hepatic C virus (HCV)-related HCC. METHODS: The current study included 138 patients with HCV-related HCC recruited from the Hepatobiliary and Interventional Radiology Units at Alexandria's main university hospitals and 40 healthy individuals as controls...

INTRODUCTION: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is the standard of care for selected cases of primary or secondary peritoneal surface malignancies. The study aims to verify the postoperative advantages of laparoscopic CRS-HIPEC. METHODS: A retrospective analysis of patients who underwent CRS-HIPEC at our institution was performed. Records were extracted from a prospectively maintained database. Patients were divided into two groups, laparoscopic CRS-HIPEC and open CRS-HIPEC, and matched for age, ASA, comorbidities, Prior Surgical Score (PSS), and Peritoneal Cancer Index (PCI) using propensity score analysis...

PURPOSE: Risk factors of gallbladder cancer (GBC) are not well-defined resulting in greater than 60% of GBCs being diagnosed incidentally following cholecystectomy performed for presumed benign indications. As most localized GBCs require more extensive oncologic surgery beyond cholecystectomy, this study aims to examine factors associated with incidentally found GBC to improve preoperative and intraoperative diagnoses. METHODS: The American College of Surgeons National Surgical Quality Improvement Program Database from 2007 to 2017 was used to identify cholecystectomies performed with and without a final diagnosis of GBC...

PURPOSE: Gastric cancer is the 5th most common malignancy worldwide. As early detection increases and treatments for gastric cancer improve, the number of gastric cancer survivors grows. METHODS: Here, we review the diagnosis and management of gastric cancer and discuss important considerations for gastric cancer survivorship including cancer surveillance, weight loss, malnutrition, fatigue, specific complications related to surgery and radiation, quality of life in gastric cancer survivorship, health behavior, and models of survivorship...

PURPOSE: Ano-uro-genital (AUG) Mucosal Melanoma UK guidelines recommended a less radical surgical strategy for anorectal melanoma (ARM) where possible. We report our experience of ARM consistent with that approach including clinical presentation, intervention undertaken and prognosis. METHODS: We present a retrospective study of 15 consecutive patients with ARM surgically treated between November 2014 and April 2023. Patients were divided into the two surgery types: wide local excision (WLE, n = 9) and abdominoperineal resection (APR, n = 6)...

We aimed to establish a prognostic model to evaluate the risk of postoperative anastomotic recurrence in patients with Siewert II or III adenocarcinoma who did not receive neoadjuvant therapy. METHODS: We included 366 patients with Siewert II or III adenocarcinoma who were treated with radical gastrectomy without neoadjuvant therapy at Fujian Provincial Hospital (FPH) between 2012 and 2018 as the development cohort...

INTRODUCTION: POLE mutant phenotype in colon adenocarcinomas represents a rare molecular subtype. These tumours are generally responsive to immune-checkpoint inhibition therapy and, therefore, are currently considered as a subtype with good prognosis. We hereby present the first detailed case presentation of a POLE mutant colon adenocarcinoma with useful microscopic features. CASE REPORT: A 53-year-old male patient's colon adenocarcinoma histologically showed wide variety of growth patterns and massive intra- and peritumoural lymphocytic infiltrate...

BACKGROUND: For relief of bowel obstruction in left-sided obstructive colon cancer (LSOCC), a self-expandable metal stent (SEMS) or decompressing stoma (DS) can be placed. In a curative setting, these two strategies have been extensively studied as a bridge to elective resection. Guidelines recommend SEMS as the preferred option in the palliative setting, but adherence in daily practice is unknown. Therefore, this study aimed to gain more insight into patients with LSOCC who received palliative treatment with SEMS or DS at a national level...
