Background: Gastric cancer (GC) remains a serious health concern and is characterized by a multifactorial etiology involving both genetic and epigenetic factors. The aim of the current study was to examine the relationship between Human leukocyte antigen (HLA)-G 3'UTR polymorphisms and the expression of HLA-G in both tumor tissues and plasma samples from patients with GC in the Tunisian population.

Methods: HLA-G 3'UTR polymorphisms (14pb Insertion/deletion and + 3142C/G) were identified by polymerase chain reaction (PCR) or Sanger sequencing.

Article Synopsis
  • HLA-G 14-bp insertion/deletion polymorphism is linked to cancer risk, particularly associated with the D allele, suggesting it may contribute to cancer cell escape mechanisms.
  • A meta-analysis of 39 studies showed a significant association between this polymorphism and breast cancer, with specific variations in risk based on ethnicity and geographic location.
  • Significant cancer risks linked to the D allele were observed in populations from North Africa, the Middle East, and South America, but no such risks were noted in Europe or North Asia.

Introduction: Perivascular epithelioid cell tumors are uncommon mesenchymal tumors. The genital tract is the most common extrarenal location. Preoperative diagnosis is rarely achieved owing to non-specific symptoms and imaging features.

Article Synopsis
  • Inguinal lymph node metastasis and the number of metastatic lymph nodes (NMLN) are key prognostic factors in vulvar squamous cell carcinoma (VSCC), but the lymph node ratio (LNR) also reflects lymphadenectomy effectiveness.
  • This study analyzed data from 192 VSCC patients to assess the impact of LNR and lymph node count on overall survival (OS) and recurrence-free survival (RFS).
  • Results indicated significant findings with a 5-year OS of 52.5% and 5-year RFS of 55.8%, highlighting LNR, FIGO stage, and negative margins as critical independent prognostic factors.

Background And Aim: As the presence of single nucleotide polymorphisms (SNPs) in the interleukin gene continues to be a major challenge in the development of effective therapies for digestive cancers, this case-control study was conducted to assess the possible influence of genotype, haplotype and diplotype for two SNPs (-1082A/G (rs1800896) and -592A/C (rs1800872)) located in the promoter region of gene on the incidence, severity and prognosis of colorectal cancer (CRC) in Tunisians.

Methods: gene SNPs were analyzed in 130 CRC cases and 165 healthy subjects (HS) using PCR-SSP.

Results: For the -1082A/G SNP, the comparison of genotype frequencies between cases and HS groups showed that the G allele significantly reduced CRC risk under the recessive model (GG vs.

Metastasis to the pancreas from malignant tumors is a rare event, representing only 1% to 2% of all pancreatic neoplasms. They occur in 2 different clinicopathological settings: as a manifestation in widespread metastatic disease or as an isolated mass in the pancreas. We report the case of a 41-year-old woman who had a history of invasive lobular breast cancer treated with radical surgery, chemotherapy, and radiotherapy.

Introduction: Vaginal metastasis from colorectal cancer is a rare occurrence, typically associated with other metastatic lesions. Isolated metastasis is exceedingly uncommon, with only a few cases documented in the literature. Vaginal involvement in colorectal cancer primarily results from direct contiguous spread from the primary tumor.

Article Synopsis
  • Sex cord-stromal tumors with annular tubules are very rare ovarian tumors that make up less than 1% of ovarian cancers and can recur decades after initial treatment.
  • A 16-year-old girl diagnosed and treated for this tumor experienced significant delays in follow-up, leading to late recurrences detected via imaging and elevated serum inhibin B levels.
  • Surgical removal of the tumor is crucial for treatment, but due to the rarity of these tumors, there's often a lack of early detection and staging, highlighting the importance of ongoing monitoring for patients.

Introduction And Importance: Solitary fibrous tumors (SFTs), rare mesenchymal tumors, occur in diverse locations. Retroperitoneal and pelvic SFTs are extremely uncommon, challenging to identify due to vague clinical and radiological features. We present a high-risk SFT case in the retropubic Retzius space.

Background: Azathioprine, which is an immunosuppressive agent commonly used for chronic inflammatory bowel disease, may be associated with an increased risk of certain cancers such as hematologic malignancies.

Case Report: A 50-year-old man with a 27-year history of Crohn's disease had been under azathioprine treatment at a dose of 2.5 mg/kg/day (150 mg/day) since 2007, after ileocecal resection to avoid postoperative recurrences.

Langerhans histiocytosis or Langerhans cell histiocytosis (LCH) is a rare benign pathology representing less than 1% of orbital tumors. It can cause either localized or generalized lesions, leading to the destruction of hard and soft tissues. Eosinophilic granuloma is the most benign form and the predominant clinical presentation of LCH.

Background/objective: Conflicting results on the association between HLA-G and digestive cancers were reported. We conducted a meta-analysis to further investigate the true relationship between HLA-G and digestive cancers (DC).

Methods: Following PRISMA guidelines, we performed a meta-analysis including 7 case-control studies on HLA-G 14-bp Insertion/deletion (I/D) polymorphism, and 15 studies on soluble HLA-G (sHLA-G).

Objectives: Human leukocyte antigen-G (HLA-G) is implicated in several cancers and is considered to be an immune checkpoint regulator. We determined the association between polymorphisms in the 3' untranslated region of HLA-G and soluble HLA-G (sHLA-G) expression with gynecological cancers (GCs).

Methods: A meta-analysis was conducted to examine the association between HLA-G14-bp insertion (I)/deletion (D) and +3142C/G polymorphism in GC and to evaluate sHLA-G expression RESULTS: We revealed a significant association between the +3142C/G polymorphism and invasive cervical cancer (ICC) based on the allelic model G versus C (odds ratio [OR] = 0.

Hepatic epithelioid angiomyolipomas are uncommon mesenchymal neoplasms. They are difficult to diagnose by imaging, especially when the fatty component is scant or absent. The gold standard for the diagnosis is histologic examination coupled with an immunohistochemical study.
