Summary: This study analyzed the factors influencing the distribution of actionable genetic alterations in colorectal carcinomas. The study found that there were differences in the distribution of certain genetic alterations based on patients' age and gender. BRAF mutation frequency also showed geographic variation. In addition, a small fraction of CRCs had simultaneous alterations in more than one driver gene.

Summary: This study assessed the clinicopathological features and prognostic values of KRAS, NRAS, BRAF, and DNA mismatch repair status in colorectal cancer (CRC) in developing countries. The mutation frequencies of KRAS, NRAS, and BRAF were 41.7%, 1.6%, and 3.8%, respectively. KRAS mutations and deficient mismatch repair (dMMR) status were associated with aggressive biological behaviors and poor differentiation, while BRAF (V600E) mutations were associated with well-differentiated tumors. The dMMR status predicted longer overall survival in all CRC patients.

Summary: KRAS mutations were common among Saudi CRC patients, while BRAF mutations were low. The presence of KRAS mutation did not impact survival. Age at diagnosis and gender were significant factors affecting survival time.

Summary: In this study, the mutation frequencies of genes in Romanian colorectal cancer patients were analyzed and compared with clinicopathological variables. The results showed correlations between these mutations and distant metastasis at diagnosis, MSI-H, proximal colon location, and well/moderately differentiated tumors. The findings of this study are generally consistent with data from other populations.

Summary: In this study, the frequency, distribution, coexistence, and clinicopathological and molecular correlations of RAS, BRAF, PIK3CA, and TP53 mutations were investigated in 104 patients with metastatic colorectal cancer from Northeastern Romania. TP53 was the most frequently mutated gene (73.1%), followed by KRAS (45.2%) and PIK3CA (6.7%). The study provides novel insights into genetic variations specific to the population from Northeastern Romania and enables the development of genetic profiles in a developing country with limited access to specialized genetic tests.

Summary: The aim of this study was to investigate the incidence, molecular patterns, and associations with clinical parameters of KRAS/NRAS and BRAF mutations in colorectal cancer. KRAS mutation was the most common, with KRAS G12D being the most common mutation pattern. BRAF(V600E) was the most common BRAF mutation. Furthermore, there were associations observed between these mutations and age, gender, and tumor localization.

Summary: Elevated levels of C-reactive protein (CRP) in the blood have been associated with colorectal cancer (CRC) survival. This study examined the genetic variants associated with CRP levels and their interactions with sex and lifestyle factors in relation to CRC-specific mortality. The results showed a significant interaction between a genetic variant and sex in determining CRC-specific mortality.

Summary: This study found that mutations in the KRAS, NRAS and BRAF genes are not random and depend on the localization of colorectal cancer tumors. The mutation detection rate was significantly higher in women than in men, and tumors in the rectum and sigmoid colon were the most commonly observed in all patients.

Summary: The limited genetic profile of colorectal cancer (CRC) patients in Iran, except for KRAS exon2 and BRAF V600F mutations, was investigated in this study. Mutations in KRAS, NRAS, BRAF, and PIK3CA were identified and their relationships with clinicopathological features of CRC were explored.

Summary: The study aimed to investigate the relationship between HLA binding preferences and the molecular functions of presented proteins. Through large-scale predictions of ligand binding in the human proteome and statistical analysis, we observed significant differences in the molecular functions of presented proteins among different HLA variants. These differences may explain the protective or susceptibility effects of certain HLA alleles in infectious diseases, autoimmune diseases, and cancers.

Summary: The study revealed that in colorectal cancer patients, the mutation groups of KRAS/NRAS/BRAF had significantly higher SUVmax and T/NT values compared to the wild-type group. The ROC curve results showed that the cutoff values for T/NT and SUVmax were 5.14 and 12.40, with corresponding predictive accuracies of 0.682 and 0.647, respectively.

Summary: Despite strong evidence of disease control with maintenance therapy, overall survival (OS) remains unaffected. The FOCUS4-N trial demonstrated significant efficacy in progression-free survival (PFS) with maintenance capecitabine therapy, but no significant improvement in OS. Toxicity between the capecitabine and active monitoring groups was comparable, with expected side effects such as fatigue, diarrhea, and hand-foot syndrome.

Summary: This study provides a robust external validation of the 2003 Leibovich score using contemporary data, demonstrating its discriminative accuracy and calibration in predicting risk for patients with locally advanced renal cell carcinoma (RCC). The score can be used to guide risk stratification in adjuvant clinical trials for RCC patients.
