It has been suggested that the relationship between reactive changes in the bronchial mucosa and NSCLC progression may be caused by the functional status of monocytic-macrophage cells as important participants in infammation, which determines both the risk of premalignant changes in the epithelium and malignant progression. The purpose of the study was to investigate the phenotypic profle of peripheral blood monocytes and macrophages induced from monocytes in vitro depending on the state of respiratory epithelium in NSCLC patients. Material and Methods . The study included 39 patients with newly diagnosed NSCLC. Based on the morphological examination of small bronchi taken at the distance of 3–5 cm from the tumor, patients were divided into the following groups depending on the type of pretumor changes: no pretumor changes (n=6), isolated basal cell hyperplasia (BCH) (n=13), combination of BCH and squamous metaplasia (SM) (n=3), combination of unchanged epithelium and focal BCH (n=17). The phenotypic features of peripheral blood monocytes and in vitro -induced macrophages were assessed before treatment using fow cytometry. Results . The state of the respiratory epithelium in NSCLC patients prior to the start of anticancer treatment was associated with the phenotypic features of peripheral blood monocytes, but not with the profle of macrophages induced from them. Distortion of the response of induced macrophages to the polarizing stimuli was observed in NSCLC patients: the cultured cells responded to both M1 and M2 inducers (LPS and IL-4, respectively) with a phenotype shift to M2, while the CD206 marker expression varied depending on the presence and type of pretumor changes. Conclusion . The phenotypic profle of peripheral blood monocytes was associated with the state of the respiratory epithelium in NSCLC patients before anti-tumor treatment, but not with the phenotypic features of induced macrophages.","PeriodicalId":21881,"journal":{"name":"Siberian journal of oncology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135204977","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}

A favorable prognosis of the disease, ability to reproduce, young age and the absence of children serve as an incentive to decide on the need for childbearing. There is concern, that the mutagenic effects of chemotherapy in germ cells, the ability to induce epigenetic changes in them, may have phenotypic manifestations in offspring. Conception in the early stages after treatment (impact on mature and differentiating germ cells) has been proven to increase the risk of defective offspring. Data on the health of the offspring of patients conceived in the long term after treatment (impact on stem spermatogenic cells) are contradictory. The aim of the study was to assess long-term toxic effects of cytostatic drugs in the male rat offspring copulated in terms corresponding to the effect on stem spermatogonial cells (SSCs). Material and Methods . The experiments were carried out on autobred male Wistar rats (n=140), aged 2.5 months, 70 of which made up the group of intact animals. The effect of cytostatic drugs (etoposide, irinotecan, cisplatin, carboplatin, methotrexate, farmorubicin, and paclitaxel) injected 3 and 6 months before mating was assessed on the offspring of intact female and male rats. Results . The male rat offspring treated with cytostatic drugs was found to be viable. Gross external developmental anomalies were detected in 2 cases. In several offspring, a slowdown in physical development, decrease in the rate of formation of sensory-motor refexes and learning ability were observed. The most toxic drugs were etoposide and paclitaxel. Conclusion . The offspring of rats treated with cytostatic drugs in terms corresponding to the effect on the SSCs is at risk. The degree of severity of long-term effects varies signifcantly and depends on the type of the drugs used. A decrease in the ability to learn is the most frequently detected abnormalities in offspring. Judging by the timing of conception after cytostatic exposure, a signifcant increase in the period of time after the administration of the drug before mating is not always justifed.","PeriodicalId":21881,"journal":{"name":"Siberian journal of oncology","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135204976","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}

Depending on the stage or location of the tumor, kidney resection or nephrectomy is the gold standard of treatment for renal cell carcinoma Preservation of organ function is essential for patients with localized tumors, especially with one kidney, chronic kidney disease, proteinuria, or multiple/bilateral masses. An important goal of kidney resection is to preserve the functional activity of the organ; however, the surgery leads to its decrease because of the loss of vascularized nephrons and irreversible ischemic damage. Description of the clinical case . A 24-year-old female was diagnosed with cT1bN0M0, Stage I right kidney cancer. An abdominal cavity and retroperitoneal MSCT with intravenous contrast showed a mass in the right kidney, extending into the renal sinus and causing pyelocalicoectasia. A laparoscopic resection of the right kidney was performed using the patented technique developed at the P.A. Herzen Moscow Oncology Research Institute and providing selective intra-arterial cold ischemia. This was prompted by the complex tumor anatomy, which indicated a prolonged kidney ischemia. Conclusion . Cold arterial perfusion has several advantages. First, it quickly cools the renal parenchyma to 25 °C, enabling faster and more comfortable kidney resection and suturing. Second, it eliminates the reverse venous blood fow caused by the positive perfusion pressure in the collecting system. Third, it does not imply the additional objects (for example, ice or clamps) in the work area, therefore not affecting the intraoperative view. The literature suggests hypothermia as the method of choice in most diffcult cases (resection of a single kidney, a large-diameter tumor, a high R.E.N.A.L. index).","PeriodicalId":21881,"journal":{"name":"Siberian journal of oncology","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135204969","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}

Material and Methods . Retrospective multicenter study collected data from 2 clinics of the Russian Federation. We considered overall survival (OS) as the main criterion of effectiveness. Progression-free survival (PFS) was the additional criterion. We performed a single- and multifactorial analysis of the effect of various parameters on PFS. To evaluate the effectiveness of regorafenib and the reintroduction of previously effective drugs, we should prove the equivalence of reintroduction of the 3rd line chemotherapy (CT) and targeted therapy to regorafenib on the 6-month overall survival, provided that the equivalence boundaries would be between 0.8 and 1.25. To reach the 0.05 probability of type I error and the 80 % study power, 178 patients (89 in each group) should be included in the study. Results . The database identifed 215 patients with morphologically confrmed metastatic colon cancer who received two or more lines of antitumor drug therapy from 2010 to 2021. We selected 132 patients with the history of regorafenib therapy and 83 patients with the reintroduction of a previously used chemotherapy regimen as 3rd line treatment. The median OS in the reintroduction and regorafenib groups did not differ (HR, 1.01; 95 % CI, 0.7–1.45; p=0.920); 6-month OS were 74 and 70 %, respectively.

Kidney injury molecule 1 (KIM-1) is considered as an early marker of cisplatininduced acute kidney injury (AKI). The aim of our study was to evaluate the changes in the burinary levels of KIM-1 (uKIM-1) in cancer patients receiving nephrotoxic CT throughout the entire course of the treatment. Material and Methods . The level of uKIM-1 was determined by enzyme immunoassay in untreated 19 patients with solid malignancies before each CT cycle (regimens with cisplatin or oxaliplatin) and every next day after cytostatic drugs administration. uKIM-1 values were normalized to urinary creatinine concentration (uKIM-1). The kidneys function was assessed by the serum creatinine (sCr) and glomerular fltration rate (GFR) value. Results . According to laboratory parameters, renal function in patients before treatment corresponded to normal ranges. During CT, an increase in sCr by more than 50 % (decrease in GFR to 68 ml/min/1.73 m 2 ), which corresponded to stage I AKI (KDIGO) was revealed in one patient (5.3 %) only. uKIM-1 levels before CT were above the upper limit of normal range (3.4 ng/mg uCr ) in 3 patients (15.8 %; median 2.1 ng/mg uCr ); at the beginning of the 2nd cycle of CT they were increased in 9 patients (47.4 %; median 3.2 ng/mg uCr ; p=0.0025, Mann-Whitney test); at the beginning of the 3rd cycle of CT uKIM-1 levels were increased in 12 patients (63.2 %; median 4.9 ng/mg uCr ; p=0.00007). During CT with cisplatin the average level of uKIM-1 increased with each subsequent cycle, in most cases it increased already the day after the administration of cytostatic drugs. No increase in uKIM-1 levels was observed during treatment with oxaliplatin-based regimens. The achievement of the threshold uKIM-1 level of 6.0 ng/mg uCr at the beginning of the next cycle of CT was signifcantly associated with a high risk of its further increase (RR=18.8; p=0.0051). Conclusion . An increase in the level of uKIM-1 after cisplatin administration can be regarded as a marker of subclinical kidney damage. In the future, the increase in uKIM-1 level at the beginning of the cycle of CT may be a reason for enhanced preventive measures or the appointment of less nephrotoxic treatment regimens.","PeriodicalId":21881,"journal":{"name":"Siberian journal of oncology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135362083","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}

Sporadic cases of squamous cell carcinoma of the rectum (rSCC) do not allow a comparative characterization of tumor aggressiveness and its response to chemoradiotherapy in relation to more common squamous cell entities, in particular, anal squamous cell carcinoma (aSCC). Objective : comparative evaluation of the short- and long-term results of chemoradiation therapy in patients with rSCC and aSCC. Material and Methods . In this retrospective study we included patients with nonmetastatic squamous cell carcinoma of the rectum (rSCC) and anal canal squamous cell carcinoma (aSCC) who received chemoradiotherapy and compared them in a 1:1 ratio using propensity-score matching. The dynamics of tumor response to treatment were compared by Kaplan-Meier survival analysis (OS and RFS) followed by Log-Rank verifcation, rate of complete response after 6 months. Results . A total of 15 pairs of matched patients were evaluated. Patients in both groups had reliably similar sex, age, histological grade, initial primary tumor size, differing only in tumor histological subtype. In the aSCC group, 60 % of patients had metastases to pelvic lymph nodes, while in the rSCC group metastases had 46.67 % (p=1). The median follow-up was 44 months. The 3-year OS in the aSCC group of patients was 76.9 %, and 71.4 % in the rSCC group (p=0.567). The 3-year DFS in the aSCC group was 66.7 %, and in the rSCC group 34.7 % (p=0.406). The rate of achieving complete clinical response to CRT after 6 months was 86.7 % for the aSCC group and only 46.7 % for the rSCC group (p=0.05). Organ-saving treatment was achieved in 93.3 % of aSCC patients and 73.3 % of rSCC patients (p=0.33). Conclusion . Overall and recurrence-free survival rates were not signifcantly decreased for rSCC patients relative to aSCC patients. This indicates a similar course and prognosis in the two diseases, but rSCC is characterized by a signifcantly lower rate of complete response to treatment.","PeriodicalId":21881,"journal":{"name":"Siberian journal of oncology","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135362086","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 current standard of care is concurrent radiation therapy (RT) and chemotherapy with mitomycin or cisplatin in combination with fuoropyrimidine drugs. One possible option for effective chemotherapy regimens with a lower toxicity is the combination of oxaliplatin and capecitabine with RT. The purpose of the study : a retrospective evaluation of the results of combined treatment of 74 patients with squamous cell carcinoma of the anus (SCCA) with the use of oxaliplatin and capecitabine. Material and Methods . The study included 74 patients (men – 12.2 %, women – 87.8 %) with stage I–III SCCA. All patients underwent megavolt photon RT (2×25), a cumulative dose of 50 Gy and a boost of 10 Gy to the anal canal. From days 1 to 14 and from days 22 to 36 of RT, capecitabine was administered orally at a dose of 825 mg/m 2 twice a day in combination with intravenous administration of oxaliplatin 50 mg/m 2 on days 1, 8, 22, and 29 of RT. If a residual tumor 6 months after completion of chemoradiotherapy was found, patients underwent surgery. Results . All 74 patients underwent RT with a cumulative dose of 60 Gy. Chemotherapy, according to the protocol, was completed in 58 (78.4 %) patients. Grade 3-4 toxicity was noted in 11 (14.9 %) patients. In 64 patients (86.5 %), a complete clinical response was registered. At least one late radiation side effects according to the RTOG (LENT SOMA) scale was noted in 48 (98.0 %) patients, including grade 3-4 complications in 12 (24.5 %) patients. With a median follow-up of 40 months (3-82) cumulative three-year local recurrence rate, overall and relapse-free survival were 15.3 ± 4.5 %, 73.7 ± 5.7 % and 53.5 ± 6.4 %, respectively. Conclusion . Combined treatment of SCCA, based on the combination of RT with chemotherapy with oxaliplatin and capecitabine, is feasible and has acceptable acute toxicity. Additional clinical studies are needed using this chemotherapy regimen in combination with modern RT techniques.","PeriodicalId":21881,"journal":{"name":"Siberian journal of oncology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135362084","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}
