Some studies have developed machine learning (ML) models for the prediction of pneumonitis following immunotherapy and radiotherapy for patients with lung cancer (LC). However, the prediction accuracy of these models remains a topic of debate. Thus, this study aims to summarize the advantages of ML methods in the early prediction of radiation pneumonitis (RP) and checkpoint inhibitor pneumonitis (CIP) in LC patients. PubMed, Cochrane, Embase, and Web of Science were searched up to March 23, 2025. The Prediction Model Risk of Bias Assessment Tool (PROBAST) was utilized to explore the risk of bias (RoB) in the included studies. A subgroup analysis was conducted based on variables including radiomics, dosiomics, and clinical characteristics. Fifty-six studies comprising 12,803 LC patients were included. Of these, 43 studies focused on the early prediction of RP, 11 studies on CIP, and 2 studies on differentiating RP and CIP. The meta-analysis revealed that the c-index of dosiomics-based models, radiomics-based models, and models based on radiomics and clinical characteristics for predicting RP was 0.82 (95% CI: 0.76-0.87), 0.80 (95% CI: 0.71-0.89), and 0.90 (95% CI: 0.86-0.94), respectively. In the prediction of CIP, the c-index for the clinical characteristics model was 0.83 (95% CI: 0.81-0.85), while the integrated radiomics and clinical characteristics model achieved a c-index of 0.86 (95% CI: 0.80-0.92). The ML-based models exhibit strong performance for predicting RP and CIP. Models that integrate dosiomics and radiomics demonstrate superior predictive performance for RP. In addition, hybrid models combining radiomics with clinical features provide excellent predictive value for CIP.

Coumarin is a natural benzopyrone compound known for its diverse pharmacological activities, including anticancer, anti-inflammatory, and antioxidant properties. But its derivatives' exploration in cancer, specially PI3K-AKT-mTOR pathways-based cancer activity not explored yet. This review aims to evaluate the anticancer potential of coumarin derivatives' by exploring their modulatory effects on the PI3K-AKT-mTOR signaling pathway across diverse cancer types. This review adopted a systematic literature approach, emphasizing studies across various cancer types and focusing on coumarin's mechanisms and therapeutic potential. Results reveal that coumarin derivatives suppress PI3K-AKT-mTOR pathway activity across cancers, such as liver, breast, and colorectal, with IC50 values ranging from 4 µM to > 200 µM in vitro and confirmed effects in vivo. The modulation of other pathways, including NF-κB and MAPK, underscores their multi-targeted anticancer action. Despite promising preclinical efficacy, challenges like low bioavailability, potential hepatotoxicity, and systemic toxicity persist. Structure-activity relationship (SAR) studies suggest that introducing specific functional groups can enhance selectivity, reduce toxicity, and improve therapeutic outcomes. The conclusion reinforces the potential of coumarin derivatives as novel anticancer agents, advocating for structural optimizations and clinical investigations to overcome pharmacokinetic barriers and maximize therapeutic benefits. This exploration offers a strategic perspective on utilizing coumarin-based molecules in advancing cancer therapeutics.

Imiquimod (IMQ) is an immunomodulatory topical drug with antiviral and antitumoral activity. Given its effectiveness and safety, IMQ is broadly off-label used for many vulvovaginal conditions as monotherapy and in association with other therapeutic approaches. However, standardized dose regimens and the total duration of therapy are still debated. This review aimed to summarize the current evidence on off-label uses of IMQ in different vulvovaginal conditions and compare its effectiveness to other gold standard treatments.

Recent research suggests a link between KRAS mutations and the effectiveness of ICIs, as KRAS-driven tumors may possess unique immunogenic features that influence the tumor microenvironment. These mutations can increase tumor mutation burden (TMB) and neoantigen load, potentially leading to improved responses to ICIs. This meta-analysis aims to consolidate existing evidence on the impact of KRAS mutations as a predictive factor for survival and treatment outcomes in patients with advanced NSCLC treated with ICIs. A comprehensive search strategy was designed by a biostatistician and pulmonologist, targeting PubMed, Web of Science, and Scopus databases up to May 2022. The outcomes assessed included overall survival (OS) and progression-free survival (PFS), reported as log hazard ratios (HRs) with corresponding standard errors (SEs). A pooled estimate of the HR effect size was calculated using Review Manager (RevMan, Cochrane Collaboration, London, UK). Heterogeneity among studies was evaluated using the Cochran Q test and the I2 statistic. Ultimately, 10 articles were deemed suitable for inclusion in the systematic review from a total of 8722 screened titles and abstracts. The presence of KRAS+ mutations had a significant prognostic factor for better OS in NSCLC patients treated with checkpoint inhibitors (HR = 0.89, 95% CI: 0.79-0.99) and for better PFS in NSCLC patients treated with checkpoint inhibitors (HR = 0.72, 95% CI: 0.59-0.87). In conclusion, our study indicates that KRAS mutations may serve as a potential positive predictive biomarker in patients with advanced non-small-cell lung cancer treated with immune checkpoint inhibitor monotherapy.

Anti-cancer drugs can be toxic to healthy cells in the body and have the potential to cause irreversible damage to ovarian tissue. This may lead to premature ovarian insufficiency. There are two main strategies to preserve fertility in women undergoing chemotherapy treatment for cancer. One is controlled ovarian hyperstimulation with gonadotropins and a protective agent for safety, followed by freezing of oocytes or embryos; the other is ovarian suppression using gonadotropin-releasing hormone agonists (GnRH agonists). This review aims to gain an understanding of the best way to support women with cancer to preserve their fertility. As breast cancer is the most common cancer in women worldwide, it is the primary focus of this review.

PurposeTo comprehensively evaluate the efficacy and safety of combining poly (ADP-ribose) polymerase (PARP) inhibitors with chemotherapy in patients with advanced breast cancer.MethodsA systematic literature search was conducted in PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov to identify randomized controlled trials (RCTs) evaluating PARP inhibitor-chemotherapy combinations. Studies reporting progression-free survival (PFS), overall survival (OS), overall response rate (ORR), and safety outcomes were included. Data extraction and quality assessment were performed independently by two reviewers, and a meta-analysis was conducted using random-effects models.ResultsOf 970 studies retrieved, four RCTs involving 1064 patients met the inclusion criteria. PARP inhibitors combined with chemotherapy significantly improved PFS (hazard ratio [HR] 0.73, 95% confidence interval [CI] 0.63-0.84, P < .0001) and showed a trend towards improved OS (HR 0.93, 95% CI 0.79-1.09, P = .36), though this was not statistically significant. There was no significant improvement in ORR (RR 1.08, 95% CI 0.98-1.20, P = .13). Regarding safety, no significant difference was observed in all grades or grade 3-4 adverse events (AEs) overall, but the combination therapy was associated with an increased risk of anemia, nausea, and diarrhea (RRs ranging from 1.14 to 1.29, all P < .01).ConclusionPARP inhibitor combined with chemotherapy is an effective option for the treatment of patients with advanced breast cancer, but its potential increased risks of specific AEs need to be weighed. Clinicians should make individualized treatment plans according to the specific conditions of patients, comprehensive consideration of efficacy and safety.

The use of plant extracts and the compounds isolated from them for the treatment of cancer is an area of active research, given their therapeutic potential. This work focused on evaluating the literature related to the antiproliferative activity of extracts obtained from plants of the genus Tabebuia and molecules isolated in vitro or in vivo. For the search, MeSH and DECS terms were employed in the PubMed, Scopus, and SciELO databases. Research has shown that plant extracts derived from plants of the genus Tabebuia exhibit potential applications in the search for new molecules with antiproliferative activity. Among the isolated molecules, the most evaluated correspond to β-lapachone (naphthoquinone); however, molecules with antiproliferative potential belonging to groups such as iridoids, flavonoids, quinones, furanonaphthoquinones, triterpenes, and polysaccharides have also been isolated and reported. Additionally, synthesized molecules have been evaluated on the basis of the modifications made to the structures of molecules isolated from the plant extracts to increase their activity, aiming to develop more potent antitumor agents for future clinical use.
