This study aimed to reveal the drug repurposing candidates for colorectal cancer (CRC) via drug repurposing methods and network biology approaches. A novel, differentially co-expressed, highly interconnected, and co-regulated prognostic gene module was identified for CRC. Based on the gene module, polyethylene glycol, gallic acid, pyrazole, cordycepin, phenothiazine, pantoprazole, cysteamine, indisulam, valinomycin, trametinib, BRD-K81473043, AZD8055, dovitinib, BRD-A17065207, and tyrphostin AG1478 presented as drugs and small molecule candidates previously studied in the CRC...

Spindle cell/sclerosing rhabdomyosarcoma (SSRMS) is a clinicopathologically and molecularly heterogeneous disease. Gene fusions have been identified in intraosseous SSRMS, consisting predominantly of EWSR1 / FUS :: TFCP2 and MEIS1 :: NCOA2 . The former often follow an aggressive clinical course; there is limited clinical follow-up available for the latter. We report here a new case of the very rare intraosseous SSRMS with MEIS1 :: NCOA2 gene fusion and include the detailed treatment course and 52 months of clinical follow-up...

Current guidelines recommend that clinically staged T1N0 esophageal cancers are to be referred to surgery or endoscopic resection. Using the National Cancer Database we identified 733 individuals with clinically staged T1N0 esophageal carcinoma, who underwent upfront surgery and did not receive any prior treatment. We assessed upstaging, which was defined as ≥ T2 disease or positive lymph nodes. Poorly-differentiated adenocarcinomas were associated with upstaging, whereas squamous cell carcinomas were not...

Telomere shortening is deeply involved in many types of cancer. Telomere length of esophageal adenocarcinoma (EAC) and Barrett's esophagus (BE) was examined in Japanese patients. Among BE from cancer free patients (Cancer free), BE from patients with EAC (Adjacent) and EAC tissue (Cancer), Cancer free group presented the longest telomeres, while Cancer group presented the shortest telomeres and Adjacent group presented intermediate telomeres. Direction of endoscopic biopsy, 2 o'clock direction was also significantly associated with shorter telomere length in non-neoplastic BE ( P  = 0...

Preclinical data suggest that IDH1/2 mutations result in defective homologous recombination repair (HRR). We hypothesized that patients with IDH1/2 mt intrahepatic cholangiocarcinoma (IHCC) would benefit more from 1L platinum chemotherapy than patients with wildtype (WT) tumors. We performed a multicenter retrospective study of 81 patients with unresectable IHCC treated with 1L platinum with a primary endpoint of clinical benefit rate (CBR). Patients with IDH1/2 mt tumors had a similar CBR and objective response rate compared to those with IDH WT disease (59% versus 54%; p = 0...

Based on an estimating model, the aim of our study was to evaluate the axillary lymph node involvement of patients with primary invasive early human epidermal growth factor receptor 2 (HER2)-positive breast cancer before receiving neoadjuvant therapy (NAT). Patients with primary surgery ( n  = 63) were compared with patients who had received NAT (combined chemo/HER2-targeted antibody therapy) before surgery ( n  = 152). In patients receiving NAT, a positive N stage was estimated in 73...

Non-small cell lung cancer remains the most common malignant cancer. We identified 43140 advanced NSCLC patients from the SEER database to develop and validate a new prognostic model. The prognostic performance was evaluated by P value, concordance index, net reclassification index, integrated discrimination improvement, and decision curve analysis. The following variables were contained in the final prognostic model: age, sex, race, TNM stage, and grade and treatment options. Compared to the AJCC staging system, this prognostic model is conducive to the implementation of individualized clinical treatment schemes and can be an important part in the precise medical care of NSCLC tumors...

Hepatocellular carcinoma (HCC) is one of the most lethal and prevalent cancers, closely associated with cirrhosis and fibrosis. This study aimed to assess the antitumor activity of oleic acid-liposomes (uncoated liposomes) upon coating with albumin against HCC. The in vitro studies revealed the high safety of the prepared uncoated and albumin-coated liposomes to normal HFB-4 cells (EC100 of 35.57 ± 0.17 and 79.133 ± 2.92 µM, respectively) with significant anticancer activity against HepG-2 cells with IC50 of 56...

This study comparatively evaluated the possible effects of recurrent and non-recurrent patient-derived Cancer-Associated Fibroblasts (CAFs-R and -NR) on the bladder cancer cell line, EJ138. Both groups of CAFs increased cisplatin resistance and altered cell cycle distribution alongside induced resistance to apoptosis. Later, the scratch assay confirmed the cell migration-inducing effects of CAFs on cells. Nonetheless, only CAFs-R managed to increase sphere-formation and clonogenic levels in EJ138 cells, which were later validated by upregulating pluripotency transcription factors...

With the SARS-CoV-2 mutations evolving and prompt of SARS-CoV-2 vaccines, no information is available on SARS-CoV-2 vaccination status in Chinese patients with lung cancer. An electronic questionnaire including sociodemographic characteristics, vaccine status, side effect post-vaccination, and attitude towards a fourth dose of vaccine was conducted within 1018 Chinese patients with lung cancer from October 18th, 2022, to November 25th, 2022. Among 1018 patients, a total of 75 (13.7%) patients reported acceptable systemic adverse events in those had received the SARS-CoV-2 vaccine (549, 54%), the most common of which was fever (39, 7%)...

Like many other aspects of hematology-oncology training, medical education experienced rapid changes throughout the COVID-19 pandemic that continue until today. We discuss some of the most transformative areas within medical education, including, but not limited to, educational philosophy; use of virtual resources; inter-institutional connections, shifts in clinical training; changes in recruitment practice; and attention to equity and diversity. Moreover, we add our own experiences to complement the limited literature addressing these topics...

Specimens of lung adenocarcinoma (AdCa) from Russian nuclear workers ( n  = 54) exposed to alpha particles and gamma rays and from individuals non-exposed to radiation ( n  = 21) were examined using immunohistochemistry. Estimated significant associations with alpha dose were negative for Ki-67 and collagen IV in AdCa. Associations with gamma-ray dose were negative for tissue inhibitor of matrix metalloproteinase 2 and caspase 3 and positive for matrix metalloproteinase 2 and leukemia inhibiting factor in AdCa...

This systematic review with embedded meta-analysis aimed to evaluate the clinical utility of circulating tumor DNA (ctDNA) in lung cancer. After screening and review of the Embase database search, 111 studies from 2015 to 2020 demonstrated ctDNA's value in prognostication/monitoring disease progression, mainly in patients with advanced/metastatic disease and non-small cell lung cancer. ctDNA positivity/detection at any time point was associated with shorter progression-free survival and overall survival, whereas ctDNA clearance/decrease during treatment was associated with lower risk of progression and death...
