Renal cell carcinoma is one of the most common urologic cancers. Due to development of modern diagnostic methods, kidney tumors are often diagnosed at early stages (cT1a-T1b). The golden standard of treatment of localized renal cell carcinoma is tumor resection. In retroperitoneoscopic access, the time to artery access is decreased, the risk of intra- and postoperative complications is reduced. Retroperitoneal access is preferable for tumors located on the lateral or posterior kidney surface.Aim. To analyze the results of treatment of patients after retroperitoneoscopic kidney resection.Materials and methods. Between 2018 and 2021, at the A.F. Tsyb Medical Radiological Research Center - branch of the National Medical Research Radiological Center 47 retroperitoneoscopic kidney resections were performed (29 (61.7 %) in men, 18 (38.3 %) in women) due to stage cT1aN0M0 renal cell carcinoma. Retrospective analysis of demographic data, comorbid status, tumor characteristics, operative time, blood loss volume, frequency and severity of complications per the Clavien-Dindo classification was performed. Complexity of resection was evaluated using the R.E.N.A.L. scale.Results. Mean patient age was 63 (38-79) years, body mass index was 29.9 (22-39) kg/m2. Tumor of the left kidney was diagnosed in 24 (51.0 %) cases, of the right kidney - in 22 (46.8 %) cases, bilateral lesions - in 1 (2.2 %) case. Mean tumor size was 22.4 (11-39) mm. Resection had low complexity in 35 (74.5 %) cases, intermediate complexity in 12 (25.5 %) cases. Mean operative time was 156 (80-280) minutes, mean warm ischemia time was 19 (7-32) minutes, number of resections with zero ischemia was 15 (31.9 %), mean blood loss volume was 53 (10-300) mL, number of resections without renal parenchyma suturing was 10 (21.3 %). Mean hospitalization time after surgery was 5 days. Postoperative complications were observed in 4 (8.5 %) cases: bleeding (severity grade II per the Clavien-Dindo classification) in 1 (2.1 %) case, postoperative infectious complications (severity grade II) - in 2 (4.2 %) cases, subcutaneous hematoma (severity grade I) - in 1 (2.1 %) case.Conclusion. Retroperitoneoscopic access is effective and safe. This is confirmed by low frequency and severity of postoperative complications. This access allows to reduce hospitalization time and pain management medication which accelerates patient mobilization and recovery. Comparative analysis shows that retroperitoneoscopic kidney resection has the same effectiveness as laparoscopic resection.","PeriodicalId":216890,"journal":{"name":"Cancer Urology","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130644674","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}

Currently, the group of intermediate risk prostate cancer (PC) includes 2 subgroups - favorable and unfavorable intermediate risk according to the National Comprehensive Cancer Network (NCCN) classification. The optimal scope of therapy is not defined for the unfavorable intermediate risk subgroup. In particular, the need for and duration of hormone therapy (HT) during combined radiotherapy (CRT) have not yet been determined.Aim. To perform a comparative analysis of the efficacy and toxicity of CRT in patients with unfavorable intermediate risk treated with and without HT.Materials and methods. Eighty-four (84) patients with unfavorable intermediate risk PC were treated with CRT at the clinic of the A.F. Tsyb Medical Radiological Research Center between May 2016 and December 2020. Patients were divided into two groups: external beam radiation therapy + brachytherapy (n = 40) and external beam radiation therapy + brachytherapy + HT (n = 44). Conformal external beam radiation therapy was delivered with conventional fractionation to a total dose of 44-46 Gy and the 192Ir high-dose rate brachytherapy was delivered with a single fraction of 15 Gy. Median duration of HT consisting of gonadotropin-releasing hormone agonist was 6 months. Median age was 65.2 years (range: 49-80 years). Median follow-up was 58.1 months (range: 18.6-83.7 months).Results. With a median follow-up of 4.8 years, progression-free survival was 95 % and 97.6 % in the external beam radiation therapy + brachytherapy group and external beam radiation therapy + brachytherapy + HT group, respectively (p = 0.578). The break between treatment stages of more than 28 days was associated with a statistically significant increase in the risk of PC recurrence (p = 0.007). Overall survival for the external beam radiation therapy + brachytherapy group versus external beam radiation therapy + brachytherapy + HT group was 97.5 and 93.2 % (p = 0.376), respectively.Late genitourinary toxicity was grade I in 8 (9.5 %) patients and grade II in 1 (1.2 %) patient.

Metastatic castration-resistant prostate cancer remains a complex problem due to patients' previous treatments and limited selection of subsequent therapies. While 2nd generation antiandrogens are initially effective, resistance to them is not an exceptional event. Mechanisms depending on androgen receptor and independent of it have been described. A special focus is on mutations in DNA repair genes, particularly genes involved in homologous recombination repair (HRR) as a possible cause of somatic genetic abnormalities specifically in progressive metastatic disease. However, data on the effect of the HRR defect on the effectiveness of antiandrogen therapy for prostate cancer are very limited, which requires additional clinical studies.Aim. To evaluate the effect of clinical, morphological, molecular and genetic factors on the effectiveness of enzalutamide antiandrogen therapy in patients with prostate cancer and known mutations in DNA repair genes involved in HRR and mismatch repair.Materials and methods. The study was performed at the Clinical Oncological Dispensary No. 1 (Krasnodar). Retrospective analysis of clinical and morphological parameters of 54 patients with prostate cancer who received enzalutamide antiandrogen therapy and with known status of germ line and somatic mutations of HRR DNA repair genes (BRCA1, BRCA2, ATM, BARD, BRIP1, CDK12, CHEK1, CHEK2, PALB2, RAD51B, RAD51C, RAD54L, FANCL) and microsatellite instability in immunohistochemical determination of mismatch repair deficit was performed. Statistical analysis was performed using IBM SPSS Statistics v.22 software.Results and conclusion. In 17 of 54 patients, pathogenic germline and somatic mutations of HRR genes were detected: 7 mutations in BRCA2 gene, 4 - in CHEK2, 2 - in BRCA1, 2 - in CDK12, 1 - in BRIP1 and 1 - in ATM. It was shown that in the group of patients with metastatic castration-resistant prostate cancer, histological grade per the International Society of Urological Pathology (ISUP) G2 (total Gleason score 7 (3 + 4)) is significantly associated with the absence of HRR mutation, and grade G3 (total Gleason score 7 (4 + 3)) was associated with HRR mutations (р <0.05). Increase in prostate-specific antigen (PSA) level/biochemical progression 12-16 weeks after enzalutamide therapy start was significantly associated with metastatic castration-resistant prostate cancer without HRR mutations (р <0.05). In case of tumor response to enzalutamide therapy, decrease in PSA level did not depend on the age of disease onset, differentiation grade, primary advancement, previous docetaxel treatment, and presence of HRR mutation. Cox multivariate regression test showed that prescription of docetaxel before enzalutamide increased the risk of PSA-progression (hazard ratio (HR) 5.160; 95 % confidence interval (CI) 1.549-17.189; р = 0.008) and radiographic progression (HR 5.161; 95 % CI 1.550-17.187; р = 0.008).

To evaluate functional activity of peripheral blood neutrophils by chemiluminescent analysis in patients with anorectal cancer after radiotherapy.Materials and methods. The study included 80 patients with anorectal cancer.

The chemiluminescence activation index with luminol is lower in patients with anorectal cancer, and with lucigenin shows no differences with the control group. The low luminol chemiluminescence maximum intensity, as well as the decrease in the synthesis of reactive secondary oxygen species in enzymatic systems, is likely regulatory intracellular limitations consequence. After treatment, patients with radioprotector showed a decrease in the number of parameters with statistically significant differences with the control group. Undesirable phenomena associated with sodium deoxyribonucleate therapy not detected in anorectal cancer patients during radiotherapy and subsequent observation period.Conclusion. During treatment, differences in chemiluminescence parameters suggest that ionizing radiation affects them in patients with anorectal cancer receiving standard chemoradiotherapy. Use of chemoradiotherapy with a radioprotector leads to indirect restoration of cellular functional activity. This is confirmed by luminol-dependent chemiluminescence faster reaching its maximum and a decrease in the number of significant differences from the control group after the start of the drug treatment.","PeriodicalId":216890,"journal":{"name":"Cancer Urology","volume":"407 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132319924","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}
