The introduction of immunotherapy based on immune checkpoint inhibitors has significantly improve the effectiveness of kidney cancer treatment. Nevertheless, not all patients respond to such treatment and there are no reliable predictive markers. Therefore, the development of a model system for assessing the cellular immune response to a tumor seems to be an urgent task.Aim. Development of a model to assess the T-cell immune response was the focus of this study.Materials and methods. Primary tumor cell culture and peripheral blood T-cell fraction were obtained under standard sterile conditions. T-cell activation were perform via anti-CD3 and anti-CD28 antibodies. The cell index was assessed using the RTCA xCELLigence biosensor technology (ACEA Biosciences, USA).Results. Tumor and T-cells from the same patient were cultured together to assess the growth rate of the tumor cell population. Measurements were taken at 30-minute intervals. The duration of observation was 24 hours. It has been shown that non-activated T-cells do not affect the proliferative properties of cultured cancer cells. On the contrary, activated T-cells suppressed the proliferative properties of cancer cells, which was associated with an increase in the proportion of Т-cells carrying the HLA-DR receptor (CD3+HLA–DR+) because of activation. Tumor-specific T-cell activity can lead to three consequences: lack of effect, partial suppression of proliferative properties, and complete death of tumor cells. In the latter case, the absence of such cells was determined by flow cytometry.Conclusion. The developed approach makes it possible to evaluate the cytotoxic properties of T cells in relation to tumor cells in a particular patient. The advantage of this method is that the measurement can be carried out in the presence of immune checkpoint inhibitors. The proposed method may be useful for evaluating the treatment regimen within the framework of personalized therapy.","PeriodicalId":216890,"journal":{"name":"Cancer Urology","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126047663","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 incidence rates continue to increase every year, therefore, the study of the quality indicators for cancer care, especially during a pandemic, is of great importance.Aim. To analyze prostate cancer incidence rates and quality indicators of cancer care in the Siberian Federal District.Materials and methods. For the calculation of cancer incidence rates, population-bases cancer registry data were used. Quality indicators were calculated according to the methodological recommendations of P.A. Hertzen Moscow Oncology Research Institute – branch of the National Medical Research Radiological Center.Results. The implementation of restrictive measures and the suspension of cancer screening programs in 2020 negatively affected the cancer care. The prostate cancer incidence rate decreased from 52.8 per 100 000 population in 2019 to 43.1 per 100 000 population in 2020, especially in the territories of the Republic of Tyva and the Omsk Region. Morphological verification in 2020 decreased compared to 2019 (97.0 % versus 97.8 %), with the exception of the Krasnoyarsk Territory and the Republic of Altai. Early prostate cancer detection increased from 62.9 to 64.0 %, and cancer detection at late stages decreased from 36.3 to 35.0 %. One-year mortality in the region decreased from 8.0 % (2019) to 7,3 % (2020), however, it increased significantly in the Republic of Tyva (from 3.2 to 40.0 %) and the Altai Republic (from 3.7 to 10.7 %). The number of patients who have been followed-up for 5 years or more increased from 40.7 to 42.3 %, except for Republic of Altai (from 32.8 to 25.0 %).Conclusion.

Due to the intimate nature of the affected area and high significance of the organ for psycho-emotional state of the patient, at the early stages of the disease organ-sparing operations are preferred allowing to minimize the effect on patient’s quality of life without affecting oncological results.Aim. To evaluate the effectiveness of treatment of early stages penile cancer using photodynamic therapy (PDT) with chlorin E6 derivatives.Materials and methods. Between 2017 and 2021, PDT with chlorin E6 derivatives to treat early-stage penile cancer was performed in 15 patients between the ages of 29 and 84 years (mean age 56.4 years). Tumor stage was Tin situ–1bN0M0. PDT was performed with preliminary administration of Photolon and Photoran photosensitizers. Laser exposure on the tumor lesions was performed 3 hours after photosensitizer administration using laser device Latus-2 (662 nm), light dose 200–300 J/cm2, power density 0.21–0.41 mW/cm2.Results. After 1 PDT session, full regression was observed in 11 (73.3 %) patients, partial regression in 4 (26.7 %) patients who underwent 2nd session 2 months later with full effect. Therefore, in all patients full regression of the tumors was achieved. Follow-up duration was 6–56 months. Recurrence was diagnosed in 1 (6.7 %) patient 36 months after PDT, 14 (93.3 %) patients are under observation without signs of local recurrence, among them for more than 4 years – 3 men, more than 3 years – 1, more than 2 years – 3, more than 1 year – 4 and more than 6 months – 3. During the follow-up, no regional or distant metastases were observed in any of the patients.Conclusion. PDT with chlorin E6 derivatives is an effective organ-sparing treatment method for early-stage penile cancer with satisfactory oncological results without negative effect on patients’ quality of life. In 93.3 % of patients, local recurrence of the disease was not observed; during follow-up no distant metastases were diagnosed. It is necessary to point out satisfactory cosmetic results of the treatment: in all patients, elastic non-deforming scars were formed with full preservation of anatomical structures of the penis, no erectile dysfunction or disruption of urination were observed after PDT.","PeriodicalId":216890,"journal":{"name":"Cancer Urology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122703913","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}

Routine pathomorphological examination of surgical specimens from 2255 patients with clinically significant local and locally advanced prostate cancer revealed 364 cases of positive resection margin.

We utilized ROC-analysis in order to determine the threshold value of the PSA density index – 0.376 ng/ml/cm3, exceeding of which was associated with statistically significant reduction in the recurrence-free survival rate. The area under the curve was 0.711 (95 % confidence interval 0.653–0.764; p <0.0001). The risk of recurrence increased with rising of PSA density.Conclusion.
