    Background. The study aims to compare the functional outcomes and quality of life in patients having variant rectal reconstruction procedures after low anterior resection for cancer.Materials and methods. A prospective randomised controlled trial enrolled 90 patients who underwent total mesorectumectomy with formation of J-pouch (J-P), side-to-end (STE) or end-to-end (ETE) anastomoses.Results and discussion. We analysed 22 J-P, 30 STE and 38 ETE patients. For technical reasons, 26.6 % J-Ps were remodelled to other anastomoses. The neorectal sensory threshold, first and permanent defecation urges and maximal tolerated volume were higher in J-P at months 3–6–12 postoperatively.Severe low anterior resection syndrome events at post-surgery month 6 were significantly more frequent in the ETE vs. J-P and STE cohorts (21, 0 and 3.3 %, respectively, p < 0.05). Stool frequency was significantly lower in J-P vs. STE and ETE at months 3–6–12. Wexner score was 3, 5, 6 at month 6 (p < 0.05) and 0, 1, 1 at month 12 for J-P, STE and ETE, respectively (p > 0.05). Evacuatory dysfunction was present at month 6 in 59.1 J-P, 33.3 STE and 21.1 % ETE.Quality of life (FIQL) in J-P and STE was significantly higher vs. ETE anastomoses in the Lifestyle (3.21, 3.22 and 3.03, respectively, p < 0.05) and Coping (3.29, 3.21 and 2.95, respectively, p < 0.05) scales to month 12 postoperatively.Conclusion. The J-pouch formation after low anterior resection ameliorates anal continence at months 3–6 post-surgery, reduces low anterior resection syndrome and improves quality of life (FIQL). The ease of implementation and irrelevance of evacuatory dysfunction in side-to-end anastomosis make it a superior choice over end-to-end surgery

    Lynch syndrome was synonymous with hereditary non-polyposis colorectal cancer for a long time, however, mapping of the DNA mismatch repair (MMR) genes has led to distinguish Lynch syndrome as an independent syndromic unit from a number of Lynch-like syndromes that phenotypically mimic with the most frequent hereditary variant of colon cancer but genetically representing quite a heterogeneous group. This article presents up to date clinical and genetic characteristics of Lynch syndrome and Lynch-like conditions.Π‘ΠΈΠ½Π΄Ρ€ΠΎΠΌ Π›ΠΈΠ½Ρ‡Π° ΠΏΡ€ΠΎΠ΄ΠΎΠ»ΠΆΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ΅ врСмя являлся синонимом наслСдствСнного Π½Π΅ΠΏΠΎΠ»ΠΈΠΏΠΎΠ·Π½ΠΎΠ³ΠΎ ΠΊΠΎΠ»ΠΎΡ€Π΅ΠΊΡ‚Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ Ρ€Π°ΠΊΠ°, ΠΎΠ΄Π½Π°ΠΊΠΎ послС картирования Π³Π΅Π½ΠΎΠ² систСмы Ρ€Π΅ΠΏΠ°Ρ€Π°Ρ†ΠΈΠΈ нСспарСнных оснований Π”ΠΠš (MMR) ΠΈ выдСлСния синдрома Π›ΠΈΠ½Ρ‡Π° Π² ΡΠ°ΠΌΠΎΡΡ‚ΠΎΡΡ‚Π΅Π»ΡŒΠ½ΡƒΡŽ Π΅Π΄ΠΈΠ½ΠΈΡ†Ρƒ Π² Π³Ρ€ΡƒΠΏΠΏΠ΅ наслСдствСнного Π½Π΅ΠΏΠΎΠ»ΠΈΠΏΠΎΠ·Π½ΠΎΠ³ΠΎ ΠΊΠΎΠ»ΠΎΡ€Π΅ΠΊΡ‚Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ Ρ€Π°ΠΊΠ° опрСдСлился ряд схоТих синдромов, фСнотипичСски ΠΌΠΈΠΌΠΈΠΊΡ€ΠΈΡ€ΡƒΡŽΡ‰ΠΈΡ… с Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ частым наслСдствСнным Π²Π°Ρ€ΠΈΠ°Π½Ρ‚ΠΎΠΌ Ρ€Π°ΠΊΠ° толстой кишки, Π½ΠΎ гСнСтичСски ΠΏΡ€Π΅Π΄ΡΡ‚Π°Π²Π»ΡΡŽΡ‰ΠΈΡ… собой Π³Π΅Ρ‚Π΅Ρ€ΠΎΠ³Π΅Π½Π½ΡƒΡŽ Π³Ρ€ΡƒΠΏΠΏΡƒ.

    Uveal melanoma (UM) is the most common primary intra-ocular malignancy. Uveal melanoma is distinct from other subtypes of melanoma by its molecular and genetic characteristics. Somatic mutations in UM tumor involve genes, such as BAP1, EIF1AX, GNA11, GNAQ and SF3B1, that determine the biology and behavior of a tumor and appear to be predictors of disease. In 25 % of cases, the development of UM is associated with hereditary diseases and can be caused by germline mutations in genes that are responsible for a particular syndrome. Several such syndromes (BAP1-associated syndrome, FAMMM-syndrome, Li-Fraumeni syndrome and etc.) have been identified. In this article we analyze the modern concept of the nature of hereditary UM and present the case of hereditary UM. УвСальная ΠΌΠ΅Π»Π°Π½ΠΎΠΌΠ° (УМ) – самоС частоС ΠΏΠ΅Ρ€Π²ΠΈΡ‡Π½ΠΎΠ΅ злокачСствСнноС Π½ΠΎΠ²ΠΎΠΎΠ±Ρ€Π°Π·ΠΎΠ²Π°Π½ΠΈΠ΅ ΡƒΠ²Π΅Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ Ρ‚Ρ€Π°ΠΊΡ‚Π° с молСкулярно-гСнСтичСскими характСристиками, ΠΏΠΎΠ·Π²ΠΎΠ»ΡΡŽΡ‰ΠΈΠΌΠΈ ΠΎΡ‚Π»ΠΈΡ‡Π°Ρ‚ΡŒ Π΅Π΅ ΠΎΡ‚ Π΄Ρ€ΡƒΠ³ΠΈΡ… ΠΏΠΎΠ΄Ρ‚ΠΈΠΏΠΎΠ² ΠΌΠ΅Π»Π°Π½ΠΎΠΌΡ‹.

    Lynch syndrome is the most common cancer-prone syndrome associated with a high risk of colorectal cancer (CRC), neoplasms of the upper gastrointestinal system, the urinary tract, the female reproductive system, brain tumours and others. The only known form of hereditary endometrial cancer is also diagnosed as part of Lynch syndrome. One or more pathogenic germline mutations in one of the mismatch repair (MMR) genes are the cause of Lynch syndrome. Mapping of MMR genes and the discovery of microsatellite instability (MSI) have given rise to the possibility of using these clue characteristics of the pathogenic process for the elaboration of a screening test for Lynch syndrome. Being highly accurate and superior to all previously developed clinical criteria and guidelines, MSI-testing along with the assessment of the expression patterns of MMR proteins by immunohistochemistry has taken the leading role in the early diagnosis of Lynch syndrome. This article focuses on a brief review about the main evolutionary stages of clinical, anamnestic, molecular and genetic criteria for Lynch syndrome together with the results of our own research on the accuracy of the Amsterdam criteria, the Bethesda guidelines and MSI-diagnostics in the determination of the indications for MMR-genotyping in colorectal cancer patients suspected for Lynch syndrome.Π‘ΠΈΠ½Π΄Ρ€ΠΎΠΌ Π›ΠΈΠ½Ρ‡Π° (Π‘Π›) – самый частый наслСдствСнный онкологичСский синдром, ассоциированный с высоким риском развития Ρ€Π°ΠΊΠ° толстой кишки, злокачСствСнных Π½ΠΎΠ²ΠΎΠΎΠ±Ρ€Π°Π·ΠΎΠ²Π°Π½ΠΈΠΉ Π²Π΅Ρ€Ρ…Π½ΠΈΡ… ΠΎΡ‚Π΄Π΅Π»ΠΎΠ² ΠΆΠ΅Π»ΡƒΠ΄ΠΎΡ‡Π½ΠΎ-ΠΊΠΈΡˆΠ΅Ρ‡Π½ΠΎΠ³ΠΎ Ρ‚Ρ€Π°ΠΊΡ‚Π°, ΠΌΠΎΡ‡Π΅Π²Ρ‹Π΄Π΅Π»ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠΉ систСмы, Π³ΠΎΠ»ΠΎΠ²Π½ΠΎΠ³ΠΎ ΠΌΠΎΠ·Π³Π°, ТСнской Ρ€Π΅ΠΏΡ€ΠΎΠ΄ΡƒΠΊΡ‚ΠΈΠ²Π½ΠΎΠΉ систСмы.

    Colorectal cancer (CRC) is one of the leading causes of death from cancer in many countries of the world, both in men and women, and these rates are on the rise. The probability of suffering from CRC is about 4–5 % and the risk for developing CRC is associated with personal features or habits such as age, chronic disease history and lifestyle, but in most cases colorectal cancer develops as a result of the degeneration of adenomatous formations or along the jagged path. Immune dysregulation, dysbiosis, and epithelial destruction contribute to colorectal cancer carcinogenesis. The gut microbiota has a relevant role, and dysbiosis situations can induce colonic carcinogenesis through a chronic inflammation mechanism. Some of the bacteria responsible for this multiphase process include Fusobacterium spp., Bacteroides fragilis and enteropathogenic Escherichia coli. moreover, CRC is caused by mutations that target oncogenes, tumour suppressor genes and genes related to DNA repair mechanisms.Considering that the average time for the development of adenocarcinoma from precancer takes about 10 years, changes in the microbiota can be a prospective marker for screening precancerous conditions of the colon, as well as the detection of changes in DNA.The work will discuss the relationship between changes in the microbial composition of the colon with the genetic mutations identified by molecular genetic sequencing.ΠšΠΎΠ»ΠΎΡ€Π΅ΠΊΡ‚Π°Π»ΡŒΠ½Ρ‹ΠΉ Ρ€Π°ΠΊ (КРР) являСтся ΠΎΠ΄Π½ΠΎΠΉ ΠΈΠ· Π²Π΅Π΄ΡƒΡ‰ΠΈΡ… ΠΏΡ€ΠΈΡ‡ΠΈΠ½ смСртности ΠΎΡ‚ онкологичСских Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ Π²ΠΎ ΠΌΠ½ΠΎΠ³ΠΈΡ… странах ΠΌΠΈΡ€Π°, ΠΊΠ°ΠΊ Ρƒ ΠΌΡƒΠΆΡ‡ΠΈΠ½, Ρ‚Π°ΠΊ ΠΈ Ρƒ ΠΆΠ΅Π½Ρ‰ΠΈΠ½, ΠΈ эти ΠΏΠΎΠΊΠ°Π·Π°Ρ‚Π΅Π»ΠΈ ΠΈΠΌΠ΅ΡŽΡ‚ Ρ‚Π΅Π½Π΄Π΅Π½Ρ†ΠΈΡŽ ΠΊ росту.

    Background. According to the literature, BRCA1-associated breast cancer (BC) most often belongs to the triple negative (TNBC) molecular subtype. The data on the contribution of other molecular subtypes to this group of patients differ among different studies.The study objective is to evaluate the frequency of different tumor molecular subtypes in BC patients with BRCA1 gene mutation treated in N. N. Blokhin National Medical Research Center of Oncology in the period from 2017 to 2020.Materials and methods. The study included BC patients with a mutation in the BRCA1 gene (n = 209) identified as a result BRCA1 mutation screening of patients with BC. DNA diagnostics was carried out on blood samples of patients using the real-time polymerase chain reaction method. After analyzing the patients primary documentation clinical and morphological data were taken into account: the age of diagnosis, the stage of the disease, the results of immunohistochemical studies (estrogen receptor status, progesterone receptor status, HER2 expression, Ki-67 proliferation index). The assignment to the particular molecular tumour subtypes was performed according to estrogen receptor status, progesterone receptor status, HER2 status and Ki67 value.Results. Clinical and pathomorphological data of 209 patients with BRCA1-associated BC were analyzed. The age at diagnosis ranged from 23 to 72 years, the median age was 40 years, the mean age was 41.46 Β± 9.82 years. BC associated with BRCA1 was found to be TNBC in 71.3 % and luminal B, HER2 negative (LumB–) in 19.1 % of the cases. Other tumour subtypes were much less common: luminal B, HER2 positive (LumB+) in 7.2 %, luminal A (LumA) in 1 % and HER2-positive (HER2+) in 1.4 % of the cases. The frequency of subtypes was estimated in different age groups (1st – patients 23–34 (n = 53), 2nd – 35–49 (n = 111), and 3rd – 50–72 (n = 45) years old). TNBC frequency was 81.1 % in the 1st group, 73.9 % in the 2nd and 53.4 % in the 3rd group; LumB– frequency was 15.1, 15.3 and 33.3 % respectively. Using the Fisher test it was shown that the differences in frequencies were statistically significant between groups 1st and 3 rd, as well as between groups 2 nd and 3 rd (p <0.05).Conclusion. TNBC was the main molecular subtype in all age groups of BC patients with BRCA1 germinal mutation, TNBC frequency was lower in the older age group. LumB– subtype was also common in BRCA1-associated tumors especially in older women.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    Lynch syndrome was synonymous with hereditary non-polyposis colorectal cancer for a long time, however, mapping of the DNA mismatch repair (MMR) genes has led to distinguish Lynch syndrome as an independent syndromic unit from a number of Lynch-like syndromes that phenotypically mimic with the most frequent hereditary variant of colon cancer but genetically representing quite a heterogeneous group. This article presents up to date clinical and genetic characteristics of Lynch syndrome and Lynch-like conditions

    HEREDITARY UVEAL MELANOMA: A REVIEW OF LITERATURE AND A CASE REPORT

    Uveal melanoma (UM) is the most common primary intra-ocular malignancy. Uveal melanoma is distinct from other subtypes of melanoma by its molecular and genetic characteristics. Somatic mutations in UM tumor involve genes, such as BAP1, EIF1AX, GNA11, GNAQ and SF3B1, that determine the biology and behavior of a tumor and appear to be predictors of disease. In 25 % of cases, the development of UM is associated with hereditary diseases and can be caused by germline mutations in genes that are responsible for a particular syndrome. Several such syndromes (BAP1-associated syndrome, FAMMM-syndrome, Li-Fraumeni syndrome and etc.) have been identified. In this article we analyze the modern concept of the nature of hereditary UM and present the case of hereditary UM

    Clinical, anamnestic, molecular and genetic criteria for Lynch syndrome

    Lynch syndrome is the most common cancer-prone syndrome associated with a high risk of colorectal cancer (CRC), neoplasms of the upper gastrointestinal system, the urinary tract, the female reproductive system, brain tumours and others. The only known form of hereditary endometrial cancer is also diagnosed as part of Lynch syndrome. One or more pathogenic germline mutations in one of the mismatch repair (MMR) genes are the cause of Lynch syndrome. Mapping of MMR genes and the discovery of microsatellite instability (MSI) have given rise to the possibility of using these clue characteristics of the pathogenic process for the elaboration of a screening test for Lynch syndrome. Being highly accurate and superior to all previously developed clinical criteria and guidelines, MSI-testing along with the assessment of the expression patterns of MMR proteins by immunohistochemistry has taken the leading role in the early diagnosis of Lynch syndrome. This article focuses on a brief review about the main evolutionary stages of clinical, anamnestic, molecular and genetic criteria for Lynch syndrome together with the results of our own research on the accuracy of the Amsterdam criteria, the Bethesda guidelines and MSI-diagnostics in the determination of the indications for MMR-genotyping in colorectal cancer patients suspected for Lynch syndrome

    Molecular biological subtypes of breast cancer in BRCA1 mutation carriers

    Background. According to the literature, BRCA1-associated breast cancer (BC) most often belongs to the triple negative (TNBC) molecular subtype. The data on the contribution of other molecular subtypes to this group of patients differ among different studies.The study objective is to evaluate the frequency of different tumor molecular subtypes in BC patients with BRCA1 gene mutation treated in N. N. Blokhin National Medical Research Center of Oncology in the period from 2017 to 2020.Materials and methods. The study included BC patients with a mutation in the BRCA1 gene (n = 209) identified as a result BRCA1 mutation screening of patients with BC. DNA diagnostics was carried out on blood samples of patients using the real-time polymerase chain reaction method. After analyzing the patients primary documentation clinical and morphological data were taken into account: the age of diagnosis, the stage of the disease, the results of immunohistochemical studies (estrogen receptor status, progesterone receptor status, HER2 expression, Ki-67 proliferation index). The assignment to the particular molecular tumour subtypes was performed according to estrogen receptor status, progesterone receptor status, HER2 status and Ki67 value.Results. Clinical and pathomorphological data of 209 patients with BRCA1-associated BC were analyzed. The age at diagnosis ranged from 23 to 72 years, the median age was 40 years, the mean age was 41.46 Β± 9.82 years. BC associated with BRCA1 was found to be TNBC in 71.3 % and luminal B, HER2 negative (LumB–) in 19.1 % of the cases. Other tumour subtypes were much less common: luminal B, HER2 positive (LumB+) in 7.2 %, luminal A (LumA) in 1 % and HER2-positive (HER2+) in 1.4 % of the cases. The frequency of subtypes was estimated in different age groups (1st – patients 23–34 (n = 53), 2nd – 35–49 (n = 111), and 3rd – 50–72 (n = 45) years old). TNBC frequency was 81.1 % in the 1st group, 73.9 % in the 2nd and 53.4 % in the 3rd group; LumB– frequency was 15.1, 15.3 and 33.3 % respectively. Using the Fisher test it was shown that the differences in frequencies were statistically significant between groups 1st and 3 rd, as well as between groups 2 nd and 3 rd (p <0.05).Conclusion. TNBC was the main molecular subtype in all age groups of BC patients with BRCA1 germinal mutation, TNBC frequency was lower in the older age group. LumB– subtype was also common in BRCA1-associated tumors especially in older women
