Patients with non-muscle invasive bladder cancer who have smoked or currently smoke may have an increased risk of disease recurrence, according to recent study results. Marilyn L. Kwan, lead author on the study and senior research scientist in the division of research at Kaiser Permanente in Oakland, California, explained that tobacco is a known risk factor for developing bladder cancer, as it accounts for up to 50% of diagnoses. However, the role of tobacco smoking on bladder cancer prognosis is unclear. She and other researchers sought to evaluate this association in a population of 1,472 patients with non-muscle invasive bladder cancer 2.3 months after diagnosis. This included patients who were former smokers (874 patients; 59.4%), current cigarette smokers (111 patients; 7.5%), smoke pipes or cigars only (67 patients; 13.7%), e-cigarettes (65 patients; 4.4%) or used marijuana (363 patients; 24.7%). Results – which were published in the journal JAMA Network Open — demonstrated that ...

Abstract Abundant evidence has indicated that the prognosis of cutaneous melanoma (CM) patients is highly complicated by the tumour immune microenvironment. We retrieved the clinical data and gene expression data of CM patients in The Cancer Genome Atlas (TCGA) database for modelling and validation analysis. Based on single-sample gene set enrichment analysis (ssGSEA) and consensus clustering analysis, CM patients were classified into three immune level groups, and the differences in the tumour immune microenvironment and clinical characteristics were evaluated. Seven immune-related CM prognostic molecules, including three mRNAs ( SUCO , BTN3A1 and TBC1D2 ), three lncRNAs ( HLA-DQB1-AS1 , C9orf139 and C22orf34 ) and one miRNA ( hsa - miR-17-5p ), were screened by differential expression analysis, ceRNA network analysis, LASSO Cox regression analysis and univariate Cox regression analysis. Their biological functions were mainly concentrated in the phospholipid metabolic process, trans...

Epithelioid sarcoma is a rare mesenchymal-origin tumor [1] present in less than 1% of patients with soft tissue tumors [2-5]. It was first described in 1970 by Ezinger [6]. According to the Surveillance, Epidemiology, and End Results (SEER) program, the incidence rate is 0.03/100,000 in the European Union and 0.05/10,000 in the United States (US), with a higher incidence in males (2:1) [7]. This tumor is divided into two histological subtypes, i.e., distal or conventional, which is characterized by being more frequent in adolescents and young adults and is located in distal extremities, and the proximal subtype, described by Guillou in 1997 [8], is more frequent in middle-aged and elderly adults, located in proximal areas of the extremities, pelvis, perineal, and genital region [5,8-11]. The proximal subtype presents a more aggressive behavior, has higher rates of recurrence and metastasis, and worse prognosis and mortality [5,8-11]. Diagnosis is made through hist...
