Prostate cancer holds one of the leading positions among malignant neoplasms in men. One of the most well-studied tumor-specific maskers is the PCA3 score in urine obtained after prostate massage. However, the study of the PCA3 score without prostate massage can significantly simplify the preanalytical phase of the study and minimize discomfort for the patient. Objective . Investigation of the diagnostic significance of PCA3, determined in urine sediment without prostate massage and its comparison with the PCA3 score after prostate massage. Materials and methods . The study included 2 groups of patients. In the first group (n = 50), the PCA3 score was assessed without prostate massage, and in the second group (n = 15) PCA3 was assessed in urine obtained before and after massage. Results. The area under the ROC-curve (AUC) for the PCA3 score without prostate massage was 0.722 (95 % confidence interval 0.579—0.865; p = 0.008). Using the ROC analysis, the threshold value, sensitivity and specificity were determined: 25, 72.41 % (95 % confidence interval 54.28— 85.30 %) and 57.14 % (95 % confidence interval 36.55—75.53 %), respectively. The PCA3 score after massage was found to be more sensitive than without prostate massage. A small volume of material, less than 20 ml, significantly affects the sensitivity of PCA3 without massage. Conclusion . PCA3 without prostate massage may serve as an option to improve the early diagnosis of prostate cancer, but its advantage over PCA3 after prostate massage has not been shown.","PeriodicalId":42924,"journal":{"name":"Onkourologiya","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67764299","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}

Prostate cancer (PCa) is one of the most common malignancies. The gold standard of PCa diagnostics is morphological examination of prostate tissues obtained using 10-12-core biopsy. However, the number of false-negative results and detected clinically insignificant forms of cancer remain high. Magnetic resonance imaging (MRI) is the most sensitive and specific method of radiation diagnosis of PCa. The use of MRI data for prostate biopsy (fusion-biopsy) increases the accuracy of this procedure. Objective : to increase the accuracy of PCa diagnostics using targeted pararectal prostate biopsy guided by computed tomography (CT)/MRI. Materials and methods . A total of 95 patients underwent CT/MRI-guided targeted pararectal biopsy between March 2015 and March 2020. The mean level of prostate specific antigen (PSA) was 13.7 ± 12.6 ng/mL. All men were found to have 1 to 3 lesions with a PI-RADS score between 3 and 5. Patients were divided into 4 groups: 1 st group (n = 33) included patients in whom transrectal access was impossible; 2 nd group (n = 22) included patients with suspected local recurrence of PCa after brachytherapy; 3 rd group (n = 28) included patients with a negative result of primary biopsy, but with growing PSA level; 4th group (n = 12) included patients who preferred targeted biopsy. We performed targeted biopsy of each suspicious lesion according to MRIscans. Then we performed ‘blind’ systematic 10-14-core biopsy, where we did not take into account the location of suspicious foci and they could be, therefore, accidentally used for sample collection for the second time. Results . Histological examination revealed PCa in 71 out of 95 patients (74.7 %): in 27 out of 33 in 1 st group (81.8 %), in 19 out of 22 in 2 nd group (86.4 %), in 17 out of 28 in 3 rd group (60.7 %), and in 8 out of 12 in 4 th group (66.7 %). In 21 patients (29.6 %), PCa was diagnosed only in samples obtained using targeted biopsy; in 9 patients (12.7 %), PCa was diagnosed only in samples after systematic biopsy; in 41 patients (57.7 % PCa was detected by both targeted and systematic biopsy. Clinically significant cancer (Gleason score ≥7) was diagnosed in 84.5 % of cases after targeted biopsy and in 70.4 % of cases after systemic biopsy. Conclusion . CT/MRI-guided prostate fusion biopsy increases the accuracy of PCa diagnostics by additional detection of clinically significant tumors, including those in patients in whom the rectal access is impossible.","PeriodicalId":42924,"journal":{"name":"Onkourologiya","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67764378","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}

ADT decreases the level of testosterone. Despite the development of new effective drugs in recent years, luteinizing gonadotropin-releasing hormone agonists are frequently administered as ADT. One of the most commonly used first-line drugs is triptorelin (Diferelin®). In Russia, patients usually receive slow-release triptorelin administered once every month or every 3 months (intramuscular injections) and once every 3 months (subcutaneous injections); the result of using different dosage forms is comparable. Triptorelin effectively keeps serum testosterone level below 20 ng/dL, thereby increasing the time to development of castration-resistant prostate cancer, overall survival of patients receiving combination treatment with radiotherapy, and reduces the severity of symptoms from the lower urinary tract. Triptorelin has a good safety profile and is generally well tolerated by patients.","PeriodicalId":42924,"journal":{"name":"Onkourologiya","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2021-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67763151","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}

The asymptomatic disease course and lack of reliable diagnostic markers lead to the fact that more than 30 % renal cancer cases discovered at an advanced stage, when the prognosis is poor because kidney tumors are resistant to standard chemotherapy and radiation. More than 30 % of renal cancer carcinoma recur or metastasize after surgical treatment. Despite the implementation of novel targeted drugs and immune point inhibitors, the 5-year survival rate for metastatic renal cancer carcinoma remains dismal. Unsatisfactory result of renal cancer treatment may be caused by high inter- and intra-tumor heterogeneity and tumor evolution during therapy, as well as the lack of predictive and on-treatment monitoring biomarkers. Liquid biopsy test that utilizes free-circulating DNA (cfDNA) in the blood of patients, opens up new opportunities for managing patients with renal cancer. The diagnostic and predictive potential of these minimally invasive biomarkers has been demonstrated for various types of cancer. The use of highly sensitive methods of cfDNA analysis may allow early cancer detection and prediction of postoperative disease recurrence before dinical and radiographic progression. Serial cfDNA samples, that were collected before and during course of treatment, can provide information about the dynamic mutational changes in the volume of the entire tumor and metastases in real time, and the emergence of drug resistance during treatment. This information may be promising toolfor optimizing patient-specific therapeutic strategies. This review is focusing on the potential clinical application of cfDNA from blood in renal cancer. ","PeriodicalId":42924,"journal":{"name":"Onkourologiya","volume":"1 1","pages":""},"PeriodicalIF":0.1,"publicationDate":"2020-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67761727","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}
