Several observational studies have reported epidemiologic associations between psoriasis and risk of some cancers, but systematic evidence is lacking. Our aim was to comprehensively estimate the association between psoriasis and the risk of 33 common cancers using systematical Mendelian randomization based on genetic data.

Glioblastoma (GBM) is the most aggressive and heterogeneous neoplasm among central nervous system tumors, with a dismal prognosis and a high recurrence rate. Among the various genetic alterations found in GBM, the amplification of epidermal growth factor receptor (EGFR) and the EGFR variant III (EGFRvIII) mutation are among the most common, though their prognostic value remains controversial. This systematic review and meta-analysis aimed to provide a comprehensive evaluation of the diagnostic and prognostic significance of EGFR amplification and the EGFRvIII mutation in GBM patients, incorporating recent studies published in the past few years to offer a more complete and up-to-date analysis. An extensive search of the PubMed, Web of Science, and Scopus databases was conducted, including studies that reported on EGFR and/or the EGFRvIII mutation status with detailed survival data. A total of 32 studies with 4208 GBM patients were included. The results indicated that EGFR amplification significantly correlated with worse OS (Overall survival) (HR = 1.27, 95% CI: 1.03-1.57), suggesting that EGFR amplification is an independent prognostic marker. The prognostic value of EGFRvIII was inconclusive, with a pooled hazard ratio for overall survival of 1.13 (95% CI: 0.94-1.36), indicating no significant effect on survival in the general population. However, a subgroup analysis suggested that EGFRvIII may be associated with poorer outcomes, particularly in recurrent GBM patients, where its prognostic significance became more evident. Furthermore, subgroup analyses based on geographic region revealed significant heterogeneity in the prognostic impact of EGFR amplification across different populations. In American cohorts, EGFR amplification was strongly associated with an increased risk of mortality (HR = 1.53, 95% CI: 1.28-1.84, p = 0.001), suggesting that it serves as a more reliable prognostic marker in this region. In contrast, no significant prognostic impact of EGFR amplification was observed in Asian (HR = 0.64, 95% CI: 0.35-1.17) or European (HR = 0.98, 95% CI: 0.80-1.19) populations. Overall, this study underscores the potential of EGFR amplification as a prognostic marker in GBM, while further research is needed to fully elucidate the role of the EGFRvIII mutation, particularly in specific patient subgroups. Clarifying these associations could offer important insights for targeted treatment strategies, improving patient outcomes.

The RET proto-oncogene, which encodes a receptor tyrosine kinase, is an important factor in the pathogenesis of medullary and papillary thyroid cancers. Selpercatinib and pralsetinib, both specific RET-kinase inhibitors, are the only FDA-approved drugs for treating RET-altered thyroid cancer. We wanted to evaluate the safety and efficacy of selpercatinib and pralsetinib in RET-altered thyroid cancers. We searched the PubMed, Embase, Cochrane, and Clinicaltrials.gov databases for randomized controlled trials and observational studies published up to March 30, 2024, and included those that reported any of the desired endpoints. The primary endpoints were 1-year progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR). Quantitative analyses were performed using the R programming language. We included four studies with 560 patients, 510 with RET-mutant and 50 with RET-fusion thyroid cancer. The 1-year PFS was 84% (95% CI, 79-88, I 2 = 43%), ORR was 69% (95% CI, 65-73, I 2 = 0) and DCR was 93% (95% CI, 89-96, I 2 = 44%). Some important grade ≥3 adverse events were hypertension (16%; 95% CI, 11-22; I 2 = 43%), diarrhea (3%; 95% CI, 2-5; I 2 = 0), increased ALT (11%; 95% CI, 8-14; I 2 = 0) and increased AST (6%; 95% CI, 4-10; I 2 = 0). In conclusion, these findings suggest that selpercatinib and pralsetinib are efficacious and safe for use in patients with RET-altered thyroid cancer.

Background: The relationship between autoimmune diseases (AIDs) and cancer is unclear and this study aimed to investigate the relationship between AIDs and cancer at the genetic level using Mendelian randomization (MR). Methods: The study employed two-sample MR and meta-analysis to investigate the association between AIDs and 33 types of cancer, following STROBE-MR guidelines. Single nucleotide polymorphisms (SNPs) associated with AIDs were used as instrumental variables, with data from FinnGen, UK Biobank, and other databases. MR analyses included sensitivity checks, heterogeneity assessments, and reverse causality tests, using multiple MR methods (inverse-variance weighted (IVW), weighted median, MR-Egger, etc.). Meta-analysis was performed on validated results to confirm findings, with statistical analyses conducted using R software. Results: The results identified eight significant associations in both discovery and replication stages. Key findings include that myasthenia gravis (MG) significantly increases the risk of oral cavity cancer, multiple sclerosis (MS) is linked to increased risks of chronic lymphocytic leukemia (CLL) and small intestine cancer, and ulcerative colitis (UC) has mixed effects, reducing the risk of uterine cervix and larynx cancers, but increasing risks for pancreatic and bladder cancers. Meta-analysis confirmed eight secondary findings, highlighting pathogenic associations such as type 1 diabetes with esophagus cancer and protective effects like systemic lupus erythematosus (SLE) against acute myelocytic leukemia. Conclusions: This study provides evidence of a causal relationship between multiple AIDs and different cancer risks at the genetic level and provides a reference for the health management of patients with AIDs.

Circulating tumor DNA (ctDNA) is a noninvasive liquid biopsy technique that can reflect the dynamic changes of tumors in real time.

Cancers of unknown primary (CUP) are associated with a high mortality rate, with limited therapeutic options available and platinum-based chemotherapy recommended as standard of care. Over the past decade, molecularly guided approaches aiming to adapt treatment strategies in patients with CUP based on predicted site of origin (site-specific approach) or genomic characteristics (tissue-agnostic approach) have been explored in clinical studies, with heterogenous findings identified.

The combination of traditional Chinese medicine (TCM) with chemotherapy has been widely applied in the treatment of gastric cancer (GC). However, previous clinical studies have been constrained by small sample sizes and a lack of investigation into the molecular mechanisms of TCM. This study aims to assess the efficacy of TCM in treating GC by leveraging the strengths of meta-analysis and multi-omics approaches while also summarizing the underlying pharmacological mechanisms.

Epidermal growth factor receptor (EGFR) mutations are present in 10-60% of all non-small cell lung cancer (NSCLC) patients and are associated with dismal prognosis. Lung cancer brain metastases (LCBM) are a common complication of lung cancer. Predictions of EGFR can help physicians in decision-making and, through optimizing treatment strategies, can result in more favorable outcomes. This systematic review and meta-analysis evaluated the predictive performance of machine learning (ML)-based models in EGFR status in NSCLC patients with brain metastasis.

This systematic review and meta-analysis examined the prevalence and clinical impact of germline variants in small cell lung cancer (SCLC). Primary objectives included estimating the prevalence of germline variants in SCLC patients, while secondary objectives focused on their effects on patient outcomes. A comprehensive search was conducted in Ovid MEDLINE, EMBASE, and gray-literature databases (as of July 2024). Studies reporting germline variants in SCLC patients were included. Data were extracted to calculate pooled prevalence and hazard ratios (HRs). Study quality was assessed using the Translating ROBBINs tool, and heterogeneity was evaluated using the I2 statistic. Of 6,117 screened studies, 124 met inclusion criteria, with 8% (10/124) reporting pathogenic/likely pathogenic (P/LP) findings. Meta-analysis using a random-effects model estimated the prevalence of P/LP germline variants in SCLC patients at 11% (95% CI: 5%-25%). Gene-level prevalence was estimated for ATM (pooled prevalence = 1%; 95% CI: 0%-5%), BRCA1 (1%; 95% CI: 1%-3%), BRCA2 (1%; 95% CI: 1%-3%), and TP53 (1%; 95% CI: 0%-3%). Patients with P/LP variants in DNA damage repair genes showed a non-significant prognostic survival benefit (pooled HR: 0.8; 95% CI: 0.51-1.29, I2 = 8%). We have conducted a comprehensive systematic review of germline variants and their impact on clinical outcomes of SCLC patients. Our meta-analysis identified an estimated prevalence of P/LP variants in SCLC patients, suggesting a rationale for screening in the clinic.

The telomerase reverse transcriptase (TERT) promoter mutations have been linked to the prognosis and survival of several cancers; however, it is still debatable in case of oral squamous cell carcinoma. The exact reason for it is currently unknown. However, considering its role in cell survival and proliferation it is imperative to evaluate the association between TERT promoter mutations and OSCC. The systematic review and meta-analysis were carried out to gather evidence for TERT promotor mutation in OSCC. Electronic databases along with grey literature were searched for relevant studies. We used fixed- or random-effect models to calculate pooled proportion, estimated odds ratios or standardized mean differences, and corresponding 95% confidence intervals (CIs). We included 13 eligible studies incorporating 816 cases. The average frequency of TERT promotor mutation was 46.1% (0.46, 95% CI, 0.33, 0.60). However, TERT promoter mutations were not associated with gender, habit (smoking and betel nut), nodal involvement, metastases, and TNM stage. C228T (189/287), C250T (73/287), C228A, and other variants of TERT mutation were frequently detected TERT mutation variant in OSCC. TERT promoter mutations could be considered as biomarkers assisting in risk stratification and prognostic prediction.

Circulating tumor DNA (ctDNA) is a promising biomarker for predicting minimal residual disease (MRD) and guiding treatment decisions in patients with colorectal cancer (CRC). This study aimed to examine the study designs and settings of ongoing clinical trials that use ctDNA to guide treatment decisions and to determine the best timing for detecting MRD in non-metastatic CRC. We searched PubMed, Embase, Web of Science, Cochrane Library, and clinicaltrials.gov for English language records. The ctDNA settings from the clinical trials were categorized by randomization to ctDNA testing, treatment options based on ctDNA results, and the timing of ctDNA testing relative to adjuvant therapy. For prospective studies, a network meta-analysis using a frequentist approach was conducted to examine the pairwise associations between different ctDNA timing strategies and MRD, defined as recurrence, relapse, and progression. The main approaches in ctDNA-based interventional trial designs were categorized as ctDNA-guided treatment, ctDNA-by-treatment, ctDNA-guided surveillance, and ctDNA-enriched adjuvant therapy for guiding treatment decisions, including both escalation and de-escalation strategies, and surveillance. Overall, both preoperative and postoperative ctDNA detection were linked to higher risks of progression, with pooled hazard ratios (95% confidence intervals) of 5.23 (2.10-13.00) and 7.95 (5.30-11.91), respectively. Among the timing strategies, ctDNA testing after adjuvant therapy was the most effective for identifying high-risk patients, strongly suggesting the presence of residual disease. This study comprehensively reviewed the clinical settings of ctDNA testing in ongoing trials and provided evidence supporting the selection of post-adjuvant therapy as the optimal timing for ctDNA testing.

The combined therapy strategy of venetoclax with hypomethylating agents (HMAs) has demonstrated encouraging efficacy in the treatment of acute myeloid leukemia (AML), particularly in elderly patients or those deemed unfit for standard treatments. However, due to differences in the research focuses of various research centers, the results have not yet comprehensively and systematically demonstrated the clinical significance of this treatment approach. Therefore, in this meta-analysis, we aimed to assess the effectiveness and safety of venetoclax in combination with HMAs for the treatment of AML. We included a total of 20 clinical studies that met the search criteria, including research focused on AML patients carrying FLT-3 and IDH mutations. Results revealed an overall response (OR) rate of 0.57 and a complete remission (CR)/complete remission with incomplete marrow recovery (CRi) rate of 0.52. Subgroup analyses indicated varying CR/CRi rates among patients with different genetic mutations, with the highest rate observed in IDH mutation carriers at 0.71, FLT-3 mutation carriers at 0.64, and TP53 mutation carriers at 0.44. Simultaneously, we observed adverse events such as anemia, neutropenia, and thrombocytopenia, underscoring the importance of careful management during venetoclax and HMAs treatment. This study emphasizes the potential of venetoclax and HMAs as a promising therapeutic approach for AML while highlighting the critical need for monitoring and managing adverse events in such treatment regimens.

Mainstreaming genetic testing refers to genetic testing for cancer susceptibility genes following cancer diagnosis, which is provided by nongenetic health professionals of the cancer-treating team. Mainstreaming can be used to guide cancer treatment and secondary cancer prevention in the patient and to identify carriers in the family members of patients who test positive through cascade testing. We aimed to assess uptake and patient-reported outcomes of mainstreaming genetic testing.

The prognostic significance of KRAS and BRAF mutations is well-established in metastatic colorectal cancer (CRC) but remains uncertain in early-stage tumors. This study retrospectively analyzed 47 stage II/III CRC patients undergoing curative surgery to assess the association of mutations in KRAS, NRAS, BRAF, and PIK3CA with overall survival (OS) and disease-free survival (DFS). Additionally, a meta-analysis was conducted to validate the prognostic relevance of these gene mutations. We included post hoc analyses of phase III randomized controlled trials (RCTs) in stage II/III patients receiving adjuvant therapy after curative resection in the meta-analysis. Pooled hazard ratio (HR) and 95% confidence interval (CI) was calculated using a random-effect model in the overall population, stratified subgroups adjusted for microsatellite instability (MSI) status, and within MSI-high (MSI-H) and microsatellite-stable (MSS) populations. In the retrospective cohort, mutations in KRAS, NRAS, BRAF, and PIK3CA were identified in 29.8%, 4.3%, 8.5%, and 14.9% of patients, respectively. No significant association between individual genes and survival was observed. However, in MSS patients, concurrent mutations were significantly associated with shorter OS and DFS (log-rank test, P < 0.05). The meta-analysis incorporated 13 eligible studies, including 15,034 patients. Pooled analyses revealed that KRAS and BRAF mutations were significantly linked to poor OS (KRAS: HR = 1.25, 95%CI: 1.06-1.47, P = 0.008; BRAF: HR = 1.43, 95%CI: 1.26-1.63, P < 0.001) and DFS (KRAS: HR = 1.36, 95%CI: 1.21-1.53, P < 0.001; BRAF: HR = 1.21, 95%CI: 1.02-1.44, P = 0.032). The prognostic impact of BRAF mutation increased with MSI adjustment compared those without MSI adjustment. In MSS tumors, KRAS-mutant patients demonstrated significantly shorter DFS (HR = 1.63, 95%CI: 1.25-2.13, P < 0.001), while BRAF-mutant patients exhibited reduced OS (HR = 1.53, 95%CI: 1.24-1.89, P < 0.001) and DFS (HR = 1.72, 95%CI: 1.20-2.46, P = 0.003) compared to wildtype patients. Conversely, no significant survival differences were found between mutant and wildtype patients in the MSI-H population. Although PIK3CA mutation was nominally associated with OS (HR = 0.86, 95%CI: 0.75-1.00, P = 0.046), the pooled result lacked robustness. In conclusion, KRAS and BRAF mutations had a negative prognostic impact on MSS stage II/III CRC patients receiving adjuvant therapy following curative resection. These patients may benefit from more effective adjuvant treatment strategies.
