1542 Background: Existent genetic tests are not able to provide effective forecasting of all cancer sites and all those methods are generally expensive. At the same time approximately 50% of population has cancer susceptibility and 10% - hereditary cancer syndromes. The purpose of this study was to develop the algorithm of monitoring to provide effective forecasting and prevention of cancer in patients with hereditary cancer susceptibility. Methods: The algorithm of monitoring of patients with family history of cancer includes 2 stage: I - diagnostic, II - treatment and rehabilitation. In the I stage patients with 3 and more relatives by blood who had cancers of any site are revealed by oncologist. Their genealogical trees are analyzed by geneticist. All those patients are registered in the registry of “cancer”-families’ members, interviewed and got all the necessary diagnostic procedures with the following multivariative analysis (of more than 200 geno- and phenotypic characteristics). Patients with determined high risk of malignancies undergo deep clinical and instrumental examination, site-by-site searching for cancer, molecular genetic tests. In the II stage individual recommendations for the patients are developed, pretumour lesions are treated, preventative surgery is performed (resection of a target organ) and the measures for strengthening of anti-tumour resistance are taken. All the patients of the registry get the periodic health examination for term of life: preventive examination once per 6 months, multivariative analysis once per 3 years. Results: The registry of “cancer”-families’ members included 421 families - 1833 patients (232 men and 1601 women at the age of 28–74). In 2003–2006 there were revealed obligatory pre-cancer lesions in 637 patients, cancers in situ - in 45 patients, and cancers of different sites - in 69 patients (in I stage - 78.3%, II stage - 18.9%, III stage - 2.8%, IV stage - 0). Conclusions: This algorithm of monitoring of the patients from the registry of “cancer”-families’ members made it possible to provide high effectiveness of cancer prevention and early detection.

Abstract Background Hereditary cancer susceptibility syndrome (HCSS) contributes to the cancer predisposition at an early age, therefore, identification of HCSS has found to be crucial for surveillance, managing therapeutic interventions and refer the patients and their families for genetic counselling. The study aimed to identify ALL patients who meet the American College of Medical Genetics (ACMG) criteria and refer them for the genetic testing for HCSS as hereditary leukemia and hematologic malignancy syndrome, and to elucidate the significance of high consanguinity with the prevalence of inherited leukemia in Pakistani population. Methods A total of 300 acute lymphoblastic leukemia patients were recruited from the Children’s Hospital, Lahore, Pakistan from December 2018 to September 2019. A structured self-reporting questionnaire based on family and medical history of the disease was utilized for the data collection. Results In our cohort, 60.40% of ALL patients were identified to meet ACMG criteria. Among them, a large number of patients (40.65%) solely fulfil the criteria due to the presence of parental consanguinity. However, parental consanguinity showed protective impact on the onset at early age of disease [OD = 0.44 (0.25–0.77), p-value = 0.00] while, a family history of cancer increased the risk of cardiotoxicity [OD = 2.46 (1.15–5.24), p-value = 0.02]. Parental consanguinity shows no significant impact on the family history of cancer and the number of relatives with cancer. Conclusions More than 50% of the ALL patients were considered the strong candidates’ for genetic testing of HCSS in the Pakistani population, and parental consanguinity was the leading criteria fulfilled by the individuals when assessed through ACMG guidelines. Our study suggests revisiting ACMG guidelines, especially for the criterion of parental consanguinity, and formulating the score based criteria based on; genetic research, the toxicology profile, physical features, personal and family history of cancer for the identification of patients for the genetic testing.

Aim: To develop a prognostic molecular genetic model for assessing the risk of development of benign and malignant tumors of female reproductive organs (FRO) in patients from cancer-affected families. Patients and Methods: The work presents the data on a comprehensive clinical examination of 210 women (90 patients with FRO cancer with aggregation of tumor pathology in families, 65 patients with benign pathology of FRO from cancer-affected families, 55 women — control group of healthy women without family history of cancer). Clinical genealogical analysis, morphological examination of tumors and molecular genetic studies of genomic DNA from peripheral blood and tumors were carried out. Results: It was established that in the families of patients with benign and malignant pathology of FRO, malignant tumors associated with Lynch II syndrome are observed. Based on the analysis of detected ESR-1, CYP 2D6*4 and mutations in BRCA1/2 genes in cancer patients and in patients with benign pathology, molecular genetic models have been developed to assess the individual risk of development of benign and malignant tumors of FRO. It has been established that these molecular genetic models and combinations of gene mutations and gene polymorphisms (SNP) by the intergene interaction that was analyzed, were found to be reliable in assessing the risk of benign and malignant pathology of the mammary gland and ovary. Conclusions: The model, which included the polymorphic variants of the T397C(ESR1)/CYP 2D6*4 genes was of the best predictive accuracy for the evaluation of the risk of benign tumors of the FRO (71.68%) and the highest reliability (p < 0.001). At the same time, all identified models of intergene interaction in the development of malignant pathology of FRO were reliable, prognostically significant with high reproduction and almost identical accuracy (65.00–68.23%). The obtained results indicate a high informativeness of such molecular genetic indices as the polymorphism of ESR1 and CYP 2D6*4 genes and mutations in BRCA1/2 genes to assess the risk of benign or malignant tumors of FRO in families of patients with family history of cancer.

The genome-wide search for the prostate cancer gene holds the promise of the availability of prostate cancer susceptibility testing in the near future. When this occurs, self-reported history of prostate cancer will be critical in determining who is eligible for cancer susceptibility testing. Little attention has been given to the reliability of self-reported family history of prostate cancer, particularly in African American men. This correlational study measured the stability of self-reported family history of prostate cancer over a one-year time period (between 1997 and 1998) with 96 African American men from a southern state. The men were asked on two separate occasions, 1 year apart, “Have any of your men blood relatives ever had prostate cancer?” The question had a prior test-retest reliability of 0.85 over a 2-week period. Forty-eight percent of the men changed their answers on the second administration. Men most likely to change their answers were low-income men and men who did not participate in a free prostate cancer screening. This research highlights the need for public genetic education and the recognition by health professionals that self-reported family history of cancer is a variable that changes as families have increased awareness and communication concerning family history of cancer.

Colorectal cancer (CRC) is the second most frequent neoplasm in Chile and its mortality rate is rising in all ages. However, studies characterizing CRC according to the age of onset are still lacking. This study aimed to identify clinical, pathological, and molecular features of CRC in Chilean patients according to the age of diagnosis: early- (≤50 years; EOCRC), intermediate- (51–69 years; IOCRC), and late-onset (≥70 years; LOCRC). The study included 426 CRC patients from Clinica Las Condes, between 2007 and 2019. A chi-square test was applied to explore associations between age of onset and clinicopathological characteristics. Body Mass Index (BMI) differences according to age of diagnosis was evaluated through t-test. Overall (OS) and cancer-specific survival (CSS) were estimated by the Kaplan–Meier method. We found significant differences between the age of onset, and gender, BMI, family history of cancer, TNM Classification of Malignant Tumors stage, OS, and CSS. EOCRC category was characterized by a family history of cancer, left-sided tumors with a more advanced stage of the disease but better survival at 10 years, and lower microsatellite instability (MSI), with predominant germline mutations. IOCRC has shown clinical similarities with the EOCRC and molecular similarities to the LOCRC, which agrees with other reports.
