Background: Gastric cancer (GC) is one the most common causes of death worldwide. Despite the decreasing rate of GC in the world through recent years, it is still the most common cancer in men and the fourth in the general population in Iran. This study aimed to assess the survival of patients with GC and to determine prognostic factors.
Materials And Methods: A total of 471 patients with GC were followed from 21 March 2003 to 21 March 2007 in the Cancer Institute of Imam Khomeini Hospital. The patients' survival rate was determined by periodical refers. The survival period considered as the time from diagnosis up to death or the end of the study. The effects of gender, age at diagnosis, tumor site, pathologic stage of disease, type of treatment used, and metastasis were evaluated by log-rank test in a univariate analysis. In addition, all the variables were evaluated simultaneously by the Cox proportional hazard (PH) model. Data were analyzed using SPSS 16 software.
Results: 357 (75.8%) out of 471 patients were male and 153 cases (32.5%) experienced death. The mean and median ages at diagnosis were 58.5 and 60.7 years respectively. Also, the survival mean and median were 41.8 ( 3.1) and 27 (1.7) months respectively. Gender, type of treatment, pathologic stage, the degree of differentiation were significantly related to survival.
Conclusions: There was a potential effective role of age at diagnosis, gender of patients and pathologic stage of disease in cancer therapy in this part of Iran. Therefore, to reduce the risk of death in patients with GC, early diagnosis of patients at a younger age and also in primary stages must be targeted.

Osteoarthritis (OA) is a complex disease of cartilage characterised by joint pain, functional limitation, and reduced quality of life with affected joint movement leading to pain and limited mobility. Current methods to diagnose OA are predominantly limited to X-ray, MRI and invasive joint fluid analysis, all of which lack chemical or molecular specificity and are limited to detection of the disease at later stages. A rapid minimally invasive and non-destructive approach to disease diagnosis is a critical unmet need.

This study aimed to compare computed tomography (CT) findings between basaloid lung squamous cell carcinoma (SCC) and non-basaloid SCC. From July 2003 to April 2021, 39 patients with surgically proven basaloid SCC were identified. For comparison, 161 patients with surgically proven non-basaloid SCC from June 2018 to January 2019 were selected consecutively.

In recent years, immune checkpoint inhibitors (ICIs) has emerged as a fundamental component of the standard treatment regimen for patients with head and neck squamous cell carcinoma (HNSCC). However, accurately predicting the treatment effectiveness of ICIs for patients at the same TNM stage remains a challenge. In this study, we first combined multi-omics data (mRNA, lncRNA, miRNA, DNA methylation, and somatic mutations) and 10 clustering algorithms, successfully identifying two distinct cancer subtypes (CSs) (CS1 and CS2).

Immune checkpoint inhibitor (ICI) therapy is the new standard treatment for advanced or metastatic hepatocellular carcinoma (HCC); however, many patients still fail to respond. This study explored the expression and prognosis of programmed death ligand 1 (PD-L1), cluster of differentiation 24 (CD24), and cluster of differentiation 47 (CD47) in patients with hepatitis B virus-associated HCC (HBV-associated HCC). We analyzed sequencing data from the Cancer Genome Atlas (TCGA) and investigated the expression of PD-L1, CD24, and CD47 in HBV-associated HCC patients by immunohistochemistry and their relationship with prognosis and clinicopathological factors.
