Early diagnosis and targeted treatment decrease patients’ death rate, pain, and treatment expenses. Liquid biopsy can be used for early cancer detection, treatment selection, and progression and treatment response monitoring. We evaluated the performance of circulating cell-free DNA (cfDNA) and formalin-fixed paraffin-embedded (FFPE) tissue DNA analyses using a commonly employed targeted therapeutic pathway in predicting the outcomes of patients with lung cancer, a common cancer with a generally poor prognosis. Methods: Patients with advanced lung cancer (n = 106) and predominantly adenocarcinoma histology donated blood samples at baseline and progression (n = 22), with matched archival FFPE biopsy samples being available for 75 patients. We set up a targeted 21-amplicon sequencing workflow for the analysis of mutations in nine genes (ALK, AKT1, BRAF, EGFR, ERBB2, KRAS, MET, NRAS, and PIK3CA). Molecular characteristics such as cfDNA concentration, number of mutations, and mutation occurrence in specific genes, were analyzed in respect of clinical outcome. To identify factors associated with overall survival (OS), a multivariate analysis was performed, using the technique of Cox regression. Results: The median age of the study population was 67 years with 53.8% male patients. The patients had primarily adenocarcinoma (79.2%) and stage IV disease (83%). The median OS was 327 (95% CI 275–514) days. Higher cfDNA concentrations were associated with poorer OS (HR = 1.670, 95% CI 1.108–2.516, P = 0.014). Detectable mutations [variant allele frequency (VAF) > 0.8%] were found in 63 (59%) patients’ baseline samples (median VAF = 1.1%). OS was significantly improved among patients with at least one mutation detected in cfDNA than among those with no mutation (HR = 0.477, 95% CI 0.313–0.727, P = 0.0006). In baseline cfDNA, patients with mutations of VAFs < 5% had significantly better OS compared to patients with mutations of VAFs ≥ 5% (HR = 3.510, 95% CI 1.672–7.370, P = 0.0009). Patients with slowly progressing disease had significantly more cfDNA mutations than did those with rapid cancer progression (P = 0.045). EGFR alterations explained half (16/33) of slowly progressing cases (median OS 953 days). All associations in FFPE biopsy material were statistically insignificant. *Corresponding author: Neeme Tõnisson, Estonian Genome Centre, Institute of Genomics, University of Tartu, Riia 23b, Tartu 51010, Estonia Check for updates ISSN: 2643-4563 DOI: 10.23937/2643-4563/1710033 Tamm et al.

However, there are patients who had an early progression after standard therapy. Our aim was to analyze the prognostic value of Ki67, CD10 and MUM1 expression in FL. Methods: Immunohistochemical staining for Ki67, CD10 and MUM1 was performed on formalin-fixed paraffin-embedded biopsy tissues from 27 patients with FL. Patients were grouped according to the levels of the Ki67 proliferation index (PI). Survival times were analyzed and the cut-off value for Ki67 PI was determined. The patients were also divided into groups according to the presence of CD10, MUM1and MUM1 positive/CD10 negative. Results: Ki-67 PI levels were as follows: ≤ 20% in 14 patients, 21-40% in 6 patients, 41-60% in 4 patients, > 60% in 3 patients. A cut-off value of 60% revealed significantly different survival rates. OS, PFS in the Ki67 > 60% group decreased significantly for 5 years, and the difference was statistically significant (37.5% vs. 100%, p = 0.000; 0% vs. 66.7%, p = 0.016; respectively). The CD10 negative group had a less favorable outcome than the positive group in the OS rate at 5 years (72% vs. 100%, p = 0.049) and the PFS rate at 5 years (25.3% vs. 72.6%, p = 0.017). OS and PFS in the group with MUM1 positive/CD10 negative decreased significantly for 5 years than in the group without MUM1 positive/CD10 negative (4.7% vs. 100%, p = 0.002; 0% vs. 66.4%, p = 0.006; respectively).

A moderate, significant, and positive correlation was found between the HLAS total score and the scores obtained from the BCPS sub-dimensions of perceived knowledge and perceived treatment belief. Results: The regression analysis on the relationship between the scores of HLAS’s change sub-dimension and BCPS sub-dimensions showed that as the scores of perceived knowledge and perceived treatment belief sub-dimensions increased, the change scores increased significantly. The explanatory value of these findings was 27.1%.

It is an extremely rare variation of non-urothelial carcinoma of the bladder, accounting for < 1% [1]. Given its rarity, no therapeutic consensus has been codified to date. We report a retrospective series of five cases and detail their anatomoclinical and therapeutic aspects. Patients and methods: This is a retrospective descriptive study of five cases of neuroendocrine carcinoma of the bladder collected at the Mohammed VI Center, between January 2017 and December 2020. The diagnosis was confirmed by immunohistochemical study. The median age is 61 years (extremes: 36-73 years), all patients are male. The average delay of consultation is 7 months (extremes: 2-12 months). Chronic smoking was found in three patients. Hematuria was the cardinal sign in 4 cases. Irritative urinary disorders such as pollakiuria and dysuria were noted in two cases. Cystoscopy showed a solid tumor in the majority of cases, located in the bladder trigone in two patients, and in the posterobasal wall in two others. Neuroendocrine carcinoma was pure in four cases and impure; associated with a poorly differentiated carcinoma component in only one case. The diagnosis of small cell neuroendocrine carcinoma of the bladder is retained after an immunohistochemical study. Chromogranin A was expressed in all cases and Synaptophysin in four cases. The extension work-up revealed locally advanced and immediately metastatic cancer in three patients (peritoneum, lung, skin). The performance status index was between 0 and 1. Palliative chemotherapy was recommended in three patients, two of whom refused all treatment. The other two patients received radiotherapy as adjuvant to neoadjuvant chemotherapy. Conclusion: The incidence of neuroendocrine carcinomas of the bladder is increasing due to the diagnostic progress by immunohistochemical means available today. They are often diagnosed at a stage that is already locally advanced or metastatic; their evolution is very rapid and their prognosis is poor. At the present time, there is no therapeutic consensus for their management.","PeriodicalId":93572,"journal":{"name":"International journal of oncology research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45448371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
