Cancers (Basel) 2022; 14:cancers14061434. [PMID: 35326583 PMCID: PMC8946582 DOI: 10.3390/cancers14061434] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2022] [Revised: 02/28/2022] [Accepted: 03/08/2022] [Indexed: 11/30/2022] Open
Abstract
Simple Summary Genotyping of BRCA genes is required for treatment with PARP inhibitors. Purposing to address treatment needs and familial cancer risk, the aim of our study was to introduce the most appropriate testing workflow in epithelial ovarian cancer patients (EOC) using germline and tumor genotyping of BRCA and other hereditary breast and/or ovarian cancer (HBOC) susceptibility genes. In consecutive patients with advanced non-mucinous EOC, who responded to platinum-based chemotherapy, germline and tumor genotyping were performed using Illumina’s next generation sequencing (NGS) panels. Sensitivity of tumor genotyping for detection of germline pathogenic/likely pathogenic variants (PV/LPV) was 96.2% for BRCA and 93.3% for HBOC genes. With germline genotyping-only strategy, 58.8% of HBOC PV/LPV and 68.4% of BRCA PV/LPV were detected. By tumor genotyping-only, 96.1% of HBOC PV/LPV and 97.4% of BRCA PV/LPV were detected. Tumor genotyping first followed by germline genotyping detects nearly all germline and somatic PV/LPV in the shortest time. Abstract Detection of germline and somatic pathogenic/likely pathogenic variants (PV/LPV) in BRCA genes is at the moment a prerequisite for use of PARP inhibitors in different treatment settings of different tumors. The aim of our study was to determine the most appropriate testing workflow in epithelial ovarian cancer (EOC) patients using germline and tumor genotyping of BRCA and other hereditary breast and/or ovarian cancer (HBOC) susceptibility genes. Consecutive patients with advanced non-mucinous EOC, who responded to platinum-based chemotherapy, were included in the study. DNA extracted from blood and FFPE tumor tissue were genotyped using NGS panels TruSightCancer/Hereditary and TruSight Tumor 170. Among 170 EOC patients, 21.8% had BRCA germline or somatic PV/LPV, and additionally 6.4% had PV/LPV in other HBOC genes. Sensitivity of tumor genotyping for detection of germline PV/LPV was 96.2% for BRCA genes and 93.3% for HBOC genes. With germline genotyping-only strategy, 58.8% of HBOC PV/LPV and 68.4% of BRCA PV/LPV were detected. By tumor genotyping-only strategy, 96.1% of HBOC PV/LPV and 97.4% of BRCA PV/LPV were detected. Genotyping of tumor first, followed by germline genotyping seems to be a reasonable approach for detection of PV/LPV in breast and/or ovarian cancer susceptibility genes in non-mucinous EOC patients.

Abstract
PURPOSE Increased access and utilization of tumor profiling of cancers in our veteran population uncovered a modest number of potentially pathogenic germline variants (PPGVs) that require genetics referral for follow-up evaluation and germline sequencing. Challenges identified specific to the veteran population include paucity of genetics providers, either at a veteran's VA facility or nearby non-VA facilities. We sought to investigate the number of veterans who would benefit from having such resources at both local and national levels. METHODS Annotated clinical reports of mutations identified by tumor-only profiling and medical records of veterans with solid tumors at the Veterans Administration Ann Arbor Healthcare System (VA AAHS) between 2015 and 2020 were reviewed. PPGVs were identified according to society recommendations (such as ESMO and American Board of Medical Genetics and Genomics), expert review, and/or previously published criteria. After the analysis of our local VA population, these same criteria were then applied to veterans in the National Precision Oncology Program (NPOP). RESULTS Two hundred eight veterans underwent tumor profiling at the VA AAHS over the defined time period. This included 20 different primary tumor sites with over half (n = 130) being advanced cancer at diagnosis. Of these, 18 veterans (8.5%) had mutations suggestive of a PPGV. Applying these criteria to the larger NPOP database (n = 20,014), a similar percentage (6%) of PPGVs were identified. CONCLUSION These results indicate a PPGV frequency (6%-9% of veterans) consistent with the prevalence of inherited cancer predisposition syndromes in the general population, underscoring the need for medical genetics as part of standard oncologic care for veterans. We explore current and future care delivery models to optimize incorporation of medical genetics and genetic counseling to best serve veterans needing such services.

Abstract
Soft-tissue sarcomas are biologically heterogenous tumors arising from connective tissues with over 100 subtypes. Although sarcomas account for <1% of all adult malignancies, retroperitoneal sarcomas are a distinct subgroup accounting for <10% of all sarcomatous tumors. There have been considerable advancements in the understanding and treatment of retroperitoneal sarcoma in the last decade, with standard treatment consisting of upfront primary surgical resection. The evidence surrounding the addition of radiation therapy remains controversial. There remains no standard with regards to systemic therapy, including immunotherapy. Adjunctive therapy remains largely dictated by expert consensus and preferences at individual centers or participation in clinical trials. In this 2021 review, we detail the anatomical boundaries of the retroperitoneum, clinical characteristics, contemporary standard of care and well as recent advancements in retroperitoneal sarcoma care. Ongoing international collaborations are encouraged to advance our understanding of this complex disease.

Abstract
GOALS AND BACKGROUND Phosphatase and tensin homolog hamartoma tumor syndrome (PHTS) is an inherited disorder that increases the risk for cancer in multiple organ systems, including breast, endometrial, thyroid, and the gastrointestinal tract. Surveillance is recommended however there lacks data to describe the change in polyposis phenotype and cancer incidence over surveillance. Our aim is to describe the polyposis phenotype and cancer incidence in PHTS patients undergoing endoscopic surveillance. STUDY PHTS patients, ages 17 through 89, who underwent at least 2 esophagogastroduodenoscopy (EGDs) or colonoscopies were identified. Number and sizes of polyps were noted, from which 5 categories were recreated. Incidence of colorectal and gastric cancer was evaluated. RESULTS Seventy patients were included. Patients were clustered and classified into 1 of 5 categories: no polyps, few small polyps (<1 cm, < 10 polyps), few large polyps (≥1 cm, < 10 polyps), many small polyps (<1 cm, ≥10 polyps), many large polyps (≥1 cm, ≥10 polyps). There was no significant difference in polyp number or size on EGD (P=0.47 and 0.83, respectively) or colonoscopy (P=0.49 and 0.10, respectively) over the surveillance period (4.8±3.9 y for stomach and 5.6±4.4 y for colon). The average interval between endoscopies was 28±24 months for EGDs and 29±23 months for colonoscopies. A stage II transverse colon adenocarcinoma and stage IV gastric adenocarcinoma were identified. Standardized incidence rates for gastric and colon cancers were 5427 (P=0.0002) and 353 (P=0.002), respectively. CONCLUSIONS PTHS individuals can be classified into polyposis phenotypes which do not change over an endoscopic surveillance period. Two cancers were associated with a large size polyp phenotype. Surveillance intervals should be determined by polyp size ≥1 cm and pathology.

Abstract
Importance Ovarian cancer is the second most common gynecologic malignancy, but the most deadly female reproductive cancer in the United States. Epithelial ovarian cancer makes up approximately 90% of all cases and is responsible for more than 90% of ovarian cancer deaths. Elective salpingectomy has been shown to reduce ovarian cancer risk when performed at the time of a benign hysterectomy. Data regarding the risks and benefits of opportunistic bilateral salpingectomy performed at the time of cesarean delivery are limited. Objective We aim to review the current evidence regarding safety and benefits of opportunistic bilateral salpingectomy at the time of cesarean delivery compared with bilateral tubal ligation. Evidence Acquisition Original research articles, review articles, and guidelines on contraception were reviewed. Conclusions and Relevance Opportunistic bilateral salpingectomy at the time of cesarean delivery is feasible and safe. Operative time may be increased up to 15 minutes for salpingectomy performed by suture ligation compared with standard tubal ligation. Women with a history of 3 or more cesarean deliveries are more likely to require an alternative procedure. It is important to counsel women that although opportunistic bilateral salpingectomy may significantly decrease the risk of ovarian cancer, it does not eliminate the risk entirely.

Abstract
Next-generation sequencing (NGS) is used increasingly in hereditary cancer patients' (HCP) management. While enabling evaluation of multiple genes simultaneously, the technology brings to light the dilemma of variant interpretation. Here, we aimed to reveal the underlying reasons for the discrepancy in the evidence titles used during variant classification according to ACMG guidelines by two different bioinformatic specialists (BIs) and two different clinical geneticists (CGs). We evaluated final reports of 1920 cancer patients and 189 different variants from 285 HCP were enrolled to the study. A total of 173 of these variants were classified as pathogenic (n = 132) and likely pathogenic (n = 41) by the BI and an additional 16 variants, that were classified as VUS by at least one interpreter and their classification would change the clinical management, were compared for their evidence titles between different specialists. The attributed evidence titles and the final classification of the variants among BIs and CGs were compared. The discrepancy between P/LP final reports was 22.5%. The discordance between CGs was 30% whereas the discordance between two BIs was almost 75%. The use of PVS1, PS3, PP3, PP5, PM1, PM2, BP1, BP4 criteria markedly varied from one expert to another. This difference was particularly noticeable in PP3, PP5, and PM1 evidence and mostly in the variants affecting splice sites like BRCA1(NM_007294.4) c.4096 + 1 G > A and CHEK2(NM_007194.4) c.592 + 3 A > T. With recent advancements in precision medicine, the importance of variant interpretations is emerging. Our study shows that variant interpretation is subjective process that is in need of concrete definitions for accurate and standard interpretation.

Abstract
Breast cancer susceptibility gene 1 (BRCA1) is a tumor suppressor gene, which is mainly involved in the repair of DNA damage, cell cycle regulation, maintenance of genome stability, and other important physiological processes. Mutations or defects in the BRCA1 gene significantly increase the risk of breast, ovarian, prostate, and other cancers in carriers. In this review, we summarized the molecular functions and regulation of BRCA1 and discussed recent insights into the detection and treatment of BRCA1 mutated breast cancer.

Abstract
Gynecologic cancers are more often caused by genetic factors than other cancers. Genetic testing has become a promising avenue for the prevention, prognosis, and treatment of cancers. This review describes molecular features of gynecologic tumors linked to hereditary syndromes, gives an overview of the current state of clinical management, and clarifies the role of gynecology in the treatment of hereditary tumors. Typical hereditary gynecologic tumors include hereditary breast and ovarian cancer, Lynch syndrome, Peutz-Jeghers syndrome, and Cowden syndrome. Multigene panel testing, which analyzes a preselected subset of genes for genetic variants, has recently become the first-choice test because it can provide more accurate risk assessment than a single test. Furthermore, comprehensive genomic cancer profiling enables personalized cancer treatment and aids in germline findings.

Abstract
Approximately 5-10% of breast cancers are hereditary, caused by germline pathogenic variants (GPVs) in breast cancer predisposition genes. To date, most studies of the prevalence of GPVs and risk of breast cancer for each gene based on cases and non-cancer controls have been conducted in Europe and the United States, and little information from Japanese populations is available. Furthermore, no studies considered confounding by established environmental factors and single nucleotide polymorphisms (SNPs) identified in genome-wide association studies (GWAS) together in GPV evaluation. To evaluate the association between GPVs in nine established breast cancer predisposition genes including BRCA1/2 and breast cancer risk in Japanese women comprehensively, we conducted a case-control study within the Hospital-based Epidemiologic Research Program at Aichi Cancer Center (629 cases and 1153 controls). The associations between GPVs and the risk of breast cancer were assessed by odds ratios (OR) and 95% confidence intervals (CI) using logistic regression models adjusted for potential confounders. A total of 25 GPVs were detected among all cases (4.0%: 95%CI:2.6-5.9), whereas four individuals carried GPVs in all controls (0.4%). OR for breast cancer by all GPVs and by GPVs in BRCA1/2 was 12.2 (4.4-34.0, P = 1.74E-06) and 16.0 (4.2-60.9, P = 5.03E-0.5), respectively. A potential confounding with GPVs was observed for the GWAS-identified SNPs, whereas not for established environmental risk factors. In conclusion, GPVs increase the risk of breast cancer in Japanese women regardless of environmental factors and GWAS-identified SNPs. Future studies investigating interactions with environment and SNPs are warranted.

Abstract
Background In 2018, BRACAnalysis® was covered by medical insurance in Japan as a companion diagnostic test for the poly ADP-ribose polymerase inhibitor olaparib. In April 2020, eligibility for BRCA1/2 genetic testing was expanded to the diagnosis of hereditary breast and ovarian cancer syndrome, and medical management including prophylactic surgery and surveillance were covered by public insurance for BRCA1/2 mutation carriers who developed breast or ovarian cancer. The amount of BRCA1/2 genetic testing has been increasing recently, but the number of subjects and the impact of testing for patients’ outcomes remain unclear. Patients and methods This study explored the potential number of patients who will be eligible for new insurance coverage for BRCA1/2 genetic testing. We analyzed 868 patients from 938 surgeries between January 2014 and September 2020 from our database. Results Overall, 372 patients (43%) were eligible for new insurance coverage for BRCA1/2 genetic testing. The most common category was family history of breast or ovarian cancer within third-degree relatives. We found that 202 patients (23%) had family history of breast or ovarian cancer. In addition, the progression-free survival was significantly lower in triple-negative breast cancer patients aged 60 years or younger compared with the other patients (P = 0.0005). Conclusion The genetic medicine for primary breast cancer patients with BRCA1/2 germline mutation is accelerating rapidly in Japan. Therefore, establishing a system for the genetic medicine would be urgent. Supplementary Information The online version contains supplementary material available at 10.1007/s12282-022-01342-4.

The Feasibility of Implementing Mainstream Germline Genetic Testing in Routine Cancer Care-A Systematic Review. Cancers (Basel) 2022; 14:cancers14041059. [PMID: 35205807 PMCID: PMC8870548 DOI: 10.3390/cancers14041059] [Citation(s) in RCA: 32] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 02/10/2022] [Accepted: 02/17/2022] [Indexed: 01/27/2023] Open
Abstract
Simple Summary Germline genetic testing for patients with cancer can have important implications for treatment, preventive options, and for family members. In a mainstream genetic testing pathway, pre-test counseling is performed by non-genetic healthcare professionals, thereby making genetic testing more accessible to all patients who might benefit from it. These mainstream genetic testing pathways are being implemented in different hospitals around the world, and for different cancer types. It is important to evaluate how a mainstream genetic testing pathway can be made sustainable and if quality of genetic care is maintained. We show in this systematic review that it is feasible to incorporate a mainstream genetic testing pathway into routine cancer care while maintaining quality of care. A training procedure for non-genetic healthcare professionals and a close collaboration between genetics and other clinical departments are highly recommended to ensure sustainability. Abstract Background: Non-genetic healthcare professionals can provide pre-test counseling and order germline genetic tests themselves, which is called mainstream genetic testing. In this systematic review, we determined whether mainstream genetic testing was feasible in daily practice while maintaining quality of genetic care. Methods: PubMed, Embase, CINAHL, and PsychINFO were searched for articles describing mainstream genetic testing initiatives in cancer care. Results: Seventeen articles, reporting on 15 studies, met the inclusion criteria. Non-genetic healthcare professionals concluded that mainstream genetic testing was possible within the timeframe of a routine consultation. In 14 studies, non-genetic healthcare professionals completed some form of training about genetics. When referral was coordinated by a genetics team, the majority of patients carrying a pathogenic variant were seen for post-test counseling by genetic healthcare professionals. The number of days between cancer diagnosis and test result disclosure was always lower in the mainstream genetic testing pathway than in the standard genetic testing pathway (e.g., pre-test counseling at genetics department). Conclusions: Mainstream genetic testing seems feasible in daily practice with no insurmountable barriers. A structured pathway with a training procedure is desirable, as well as a close collaboration between genetics and other clinical departments.

Abstract
Hereditary breast and ovarian cancer syndrome is caused by germline mutations in BRCA1/2 genes. These genes are very large and their mutations are heterogeneous and scattered throughout the coding sequence. In addition to the above-mentioned mutations, variants of uncertain/unknown significance (VUSs) have been identified in BRCA genes, which make more difficult the clinical management of the patient and risk assessment. In the last decades, several laboratories have developed different databases that contain more than 2000 variants for the two genes and integrated strategies which include multifactorial prediction models based on direct and indirect genetic evidence, to classify the VUS and attribute them a clinical significance associated with a deleterious, high-low or neutral risk. This review provides a comprehensive overview of literature studies concerning the VUSs, in order to assess their impact on the population and provide new insight for the appropriate patient management in clinical practice.

Abstract
Background BRCA‐associated breast cancers tend to have distinctive features compared to sporadic breast cancers; further characterization can aid in optimizing treatment. Methods The study evaluated a patient cohort with early‐stage estrogen receptor positive, HER2 negative invasive breast cancer who had Oncotype DX Breast Recurrence Score® analysis and genetic testing for hereditary breast and ovarian cancer syndrome. Data on patients and their breast cancers with outcomes were collected and analyzed. Results 745 patients were included, of whom 33 had pathogenic BRCA mutations (8 BRCA1, 25 BRCA2). Patients with BRCA mutations were younger and received more adjuvant chemotherapy, but less endocrine therapy and radiation therapy. BRCA‐associated breast cancers had less progesterone receptor expression, higher nuclear grade, and higher Oncotype DX Breast Recurrence Scores® with median Recurrence Score® 29, compared to 16 in cancers without mutations (p < 0.0001). Breast cancer recurrence developed in 18% of patients with BRCA mutations and 9% of patient without mutations, although multivariate analysis of relapse‐free survival was not significant, HR 1.519 (95% confidence interval [CI] 0.64–3.58; p = 0.3401). After adjusting for Recurrence Score®, overall survival by BRCA status was improved HR 0.448 (95% CI 0.06–3.34; p = 0.4333). Conclusions BRCA‐associated early‐stage hormone receptor‐positive breast cancers have higher Oncotype DX Breast Recurrence Score® compared to those without mutations. BRCA status did not significantly impact relapse‐free survival and overall survival. Larger clinical trials are needed to further assess the findings, and if confirmed, could impact clinical management of BRCA‐associated breast cancers.

Abstract
BACKGROUND Mutations in the genes called BRCA1 and BRCA2 are associated with significantly elevated lifetime risk of developing breast and ovarian cancer. This year marks 25 years since genetic tests for BRCA1/2 mutations became available to the public. Currently, comprehensive guidelines exist regarding BRCA1/2 testing and preventive measures in mutation carriers. As such, BRCA1/2 testing represents a precedent not only in genetic testing and management of genetic cancer risk, but also in bioethics. The goal of the current research was to offer a review and an ethical primer of the main ethical challenges related to BRCA testing. METHOD A systematic scoping review was undertaken following the PRISMA Extension for Scoping Reviews (PRISMA-ScR). Four databases were searched and 18 articles that met the inclusion criteria were synthetized narratively into a conceptual map. RESULTS Ethical discussions revolved around the BRCA1/2 gene discovery, how tests are distributed for clinical use, the choice to undergo testing, unresolved issues in receiving and disclosing test results, reproductive decision-making, and culture-specific ethics. Several unique properties of the latest developments in testing circumstances (e.g., incorporation of BRCA1/2 testing in multi-gene or whole genome sequence panels and tests sold directly to consumers) significantly raised the complexity of ethical debates. CONCLUSIONS Multidisciplinary ethical discussion is necessary to guide not only individual decision making but also societal practices and medical guidelines in light of the new technologies available and the latest results regarding psychological, social, and health outcomes in cancer previvors and survivors affected by BRCA mutations.

“It was a no-brainer”: A Qualitative Study of Factors Driving Previvors’ Decision-Making when Considering Risk-Reducing Salpingectomy with Delayed Oophorectomy. Gynecol Oncol Rep 2022; 40:100948. [PMID: 35265744 PMCID: PMC8898920 DOI: 10.1016/j.gore.2022.100948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 02/21/2022] [Accepted: 02/23/2022] [Indexed: 11/30/2022] Open
Abstract
Self-advocacy and building rapport with providers facilitated decision-making for RRS-DO-focused previvors. Avoiding menopause through RRS was a key motivator for RRS-DO-focused previvors. RRS-DO-focused previvors viewed RRS as a stepwise approach to risk reduction. Understanding previvor priorities and experiences can help optimize shared decision-making.
Objective Previvors are becoming more aware of the option of risk-reducing salpingectomy with delayed oophorectomy (RRS-DO) to mitigate their risk of ovarian cancer. In this qualitative study, we explored the clinical and non-clinical factors that impacted previvors’ decision-making to pursue RRS-DO as a risk reduction strategy. Methods Semi-structured telephone interviews were conducted with previvors and transcribed verbatim. Using ATLAS.ti® software, two primary investigators interpreted data through thematic analysis. After coding four interviews, the investigators discussed discrepancies between codes with a moderator and resolved and refined code. The investigators applied the universal codebook to all interviews and revised the codebook using an iterative approach. Examining codes within and across interviews allowed for major themes and patterns to emerge. Results Interviews were conducted with seventeen previvors (ages 31–46). 6 (25%) previvors had a BRCA1 mutation, 7 (41%), a BRCA2 mutation, 3 (13%), a Lynch-related mutation, and 1 (6%), other (MUTYH mutation). At the time of interview, 12 previvors (71%) were planning (6) or had undergone (6) RRS-DO, 4 (23%) were planning (1) or had undergone (3) risk reducing salpingo-oophorectomy (RRSO), and 1 (6%) was undecided. Three major themes emerged: motivating factors for selecting surgical risk reduction option, barriers complicating surgical decision-making, and facilitating factors for surgical decision-making. RRS-DO-focused previvors prioritized avoiding menopause, and they also emphasized that self-advocacy and building rapport with providers facilitated their decision-making. Conclusion By understanding previvors’ priorities and experiences, physicians can better partner with previvors as they navigate their ovarian cancer risk reduction journey. This will ultimately optimize shared decision-making.

Abstract
Hereditary cancer syndromes, which are characterized by onset at an early age and an increased risk of developing certain tumors, are caused by germline pathogenic variants in tumor suppressor genes and are mostly inherited in an autosomal dominant manner. Therefore, hereditary cancer syndromes have been used as powerful models to identify and characterize susceptibility genes associated with cancer. Furthermore, clarification of the association between genotypes and phenotypes in one disease has provided insights into the etiology of other seemingly different diseases. Molecular genetic discoveries from the study of hereditary cancer syndrome have not only changed the methods of diagnosis and management, but have also shed light on the molecular regulatory pathways that are important in the development and treatment of sporadic tumors. The main cancer susceptibility syndromes that involve gynecologic cancers include hereditary breast and ovarian cancer syndrome as well as Lynch syndrome. However, in addition to these two hereditary cancer syndromes, there are several other hereditary syndromes associated with gynecologic cancers. In the present review, we provide an overview of the clinical features, and discuss the molecular genetics, of four rare hereditary gynecological cancer syndromes; Cowden syndrome, Peutz-Jeghers syndrome, DICER1 syndrome and rhabdoid tumor predisposition syndrome 2.

Incidental germline findings during molecular profiling of tumor tissues for precision oncology: molecular survey and methodological obstacles. J Transl Med 2022; 20:29. [PMID: 35033101 PMCID: PMC8760669 DOI: 10.1186/s12967-022-03230-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 01/05/2022] [Indexed: 12/13/2022] Open
Abstract
Background A fraction of patients referred for complex molecular profiling of biopsied tumors may harbor germline variants in genes associated with the development of hereditary cancer syndromes (HCS). Neither the bioinformatic analysis nor the reporting of such incidental germline findings are standardized. Methods Data from Next-Generation Sequencing (NGS) of biopsied tumor samples referred for complex molecular profiling were analyzed for germline variants in HCS-associated genes. Analysis of variant origin was performed employing bioinformatic algorithms followed by manual curation. When possible, the origin of the variant was validated by Sanger sequencing of the sample of normal tissue. The variants’ pathogenicity was assessed according to ACMG/AMP. Results Tumors were sampled from 183 patients (Males: 75 [41.0%]; Females: 108 [59.0%]; mean [SD] age, 57.7 [13.3] years) and analysed by targeted NGS. The most common tumor types were colorectal (19%), pancreatic (13%), and lung cancer (10%). A total of 56 sequence variants in genes associated with HCS were detected in 40 patients. Of them, 17 variants found in 14 patients were predicted to be of germline origin, with 6 variants interpreted as pathogenic (PV) or likely pathogenic (LPV), and 9 as variants of uncertain significance (VUS). For the 41 out of 42 (97%) missense variants in HCS-associated genes, the results of computational prediction of variant origin were concordant with that of experimental examination. We estimate that Sanger sequencing of a sample of normal tissue would be required for ~ 1–7% of the total assessed cases with PV or LPV, when necessity to follow with genetic counselling referral in ~ 2–15% of total assessed cases (PV, LPV or VUS found in HCS genes). Conclusion Incidental findings of pathogenic germline variants are common in data from cancer patients referred for complex molecular profiling. We propose an algorithm for the management of patients with newly detected variants in genes associated with HCS.

Beyond BRCA1/2: Homologous Recombination Repair Genetic Profile in a Large Cohort of Apulian Ovarian Cancers. Cancers (Basel) 2022; 14:cancers14020365. [PMID: 35053526 PMCID: PMC8773795 DOI: 10.3390/cancers14020365] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 12/29/2021] [Accepted: 01/07/2022] [Indexed: 02/08/2023] Open
Abstract
Simple Summary Ovarian cancer (OC) is the second most common gynecologic malignancy and the most common cause of death among women with gynecologic cancer. Despite significant improvements having been made over the past decades, OC remains one of the most challenging malignancies to treat. Targeted therapies, such as PARPi, have emerged as one of the most interesting treatments for OC, particularly in women with BRCA1 or BRCA2 mutations. or those with a dysfunctional homologous recombination repair pathway. The purpose of our study is to address the role of NGS-targeted resequencing in the clinical routine of OC, focusing not only on BRCA1/2 but also on the homologous recombination repair genetic profile. Abstract Background: Pathogenic variants in homologous recombination repair (HRR) genes other than BRCA1/2 have been associated with a high risk of ovarian cancer (OC). In current clinical practice, genetic testing is generally limited to BRCA1/2. Herein, we investigated the mutational status of both BRCA1/2 and 5 HRR genes in 69 unselected OC, evaluating the advantage of multigene panel testing in everyday clinical practice. Methods: We analyzed 69 epithelial OC samples using an NGS custom multigene panel of the 5 HRR pathways genes, beyond the genetic screening routine of BRCA1/2 testing. Results: Overall, 19 pathogenic variants (27.5%) were detected. The majority (21.7%) of patients displayed a deleterious mutation in BRCA1/2, whereas 5.8% harbored a pathogenic variant in one of the HRR genes. Additionally, there were 14 (20.3%) uncertain significant variants (VUS). The assessment of germline mutational status showed that a small number of variants (five) were not detected in the corresponding blood sample. Notably, we detected one BRIP1 and four BRCA1/2 deleterious variants in the low-grade serous and endometrioid histology OC, respectively. Conclusion: We demonstrate that using a multigene panel beyond BRCA1/2 improves the diagnostic yield in OC testing, and it could produce clinically relevant results.

Abstract
Poly-ADP ribose polymerase (PARP) inhibitors are constantly increasing in their indications for use as anti-cancer treatment in various neoplasms, the majority of which are linked with BRCA deficiency. Preclinical data support the investigation of PARP inhibitors in other neoplasms exhibiting “BRCAness” or homologous recombination deficiency (HRD) as monotherapy as well as in combination with chemotherapy. With the current report we present the case of a heavily pretreated 55-year-old male patient diagnosed with stage IV ATM-deficient CRC, who was effectively treated with an off-label olaparib-irinotecan combination after exhaustion of all available treatment choices; furthermore, we discuss the existing data providing evidence for the use of PARP inhibitors in ATM-deficient CRC and encourage the implementation of next-generation sequencing (NGS) in patients with no other available treatment options.

Abstract
PURPOSE Early detection of cancer risk is essential as it is associated with a higher chance of survival, more successful treatment, and improved quality of life. Genetic testing helps at-risk patients estimate the likelihood of developing cancer in a lifetime. This study aims to indentify the factors (perceived susceptibility, severity, benefits, and self-efficacy) that impact one's decision to take the genetic test. METHODS We examined the impacts of different factors of the health belief model on the engagement of patients in genetic testing using data from the National Cancer Institute's 2020 cross-sectional nationally representative data published in 2021. Complete surveys were answered by 3,865 participants (weighted population size = 253,815,197). All estimates were weighted to be nationally representative of the US population using the jackknife weighting method for parameter estimation. We used multivariable logistic regression to test our hypotheses for patients who have taken the genetic test for cancer risk detection. We adjusted the multivariate model for age, education, income, race, sex, cancer history, familial cancer history, and education. RESULTS We tested five hypotheses using the health belief model. Respondents who had genetic testing were more likely to rely on their health care providers and genetic counselors to make their decisions. Respondents who had genetic tests also reported less reliability on other sources than doctors: for the internet and social media (odds ratio = 0.33; P < .001) and for journals and magazines (odds ratio = 0.48; P = .007). CONCLUSION The findings show that patients generally rely on suggestions from their health care providers and counselors in genetic testing decisions. These findings also indicate that health care providers play a critical role in helping patients decide whether to use genetic testing to detect cancer risk in the early stages.

Abstract
Objectives Despite the benefits of genetic counseling and testing (GCT), utilization is
particularly low among African American (AA) women who exhibit breast cancer
features that are common in BRCA-associated cancer. Underutilization is
especially problematic for AA women who are more likely to die from breast
cancer than women from any other race or ethnicity. Due to medical mistrust,
fear, and stigma that can be associated with genetic services among
racial/ethnic minorities, reliance on trusted social networks may be an
impactful strategy to increase dissemination of knowledge about hereditary
cancer risk. Informed by the social cognitive theory, the purpose of this
study is to determine: 1) which AA patients diagnosed with breast cancer and
with identified hereditary risk are sharing information about hereditary
risk with their networks; 2) the nature of the information dissemination;
and 3) if personal GCT experiences is associated with dissemination of
information about hereditary risk. Methods Among consented participants (n = 100) that completed an interview
administered using a 202-item questionnaire consisting of open- and
closed-ended questions, 62 patients were identified to be at higher risk for
breast cancer. Descriptive statistics, bivariable chi-square, Pearson’s
exact tests, and regression analyses were conducted to examine differences
in characteristics between high-risk participants who disseminated
hereditary risk information and participants who did not. Results Among high-risk participants, 25 (40%) indicated they had disseminated
information about hereditary risk to at least one member in their
family/friend network and 37 (60%) had not. Receipt of both provider
recommendations and receipt of GCT services was associated with greater odds
of disseminating information about hereditary risk with networks, OR = 4.53,
95%CI [1.33, 15.50], p = .02. Conclusion Interventions that increase self-efficacy gained through additional
personalized knowledge and experience gained through provider
recommendations and by undergoing GCT may facilitate information
dissemination among social/familial networks.

Abstract
As germline genetic testing capacities have improved over the last two decades, increasingly more people are newly diagnosed with germline cancer susceptibility mutations. In the wake of this growth, there remain limitations in both testing strategies and translation of these results into morbidity- and mortality-reducing practices, with pediatric populations remaining especially vulnerable. To face the challenges evoked by an expanding diversity of germline cancer mutations, we can draw upon a model cancer-associated genetic condition for which we have developed a breadth of expertise in managing, Trisomy 21. We can additionally apply advances in other disciplines, such as oncofertility and pharmacogenomics, to enhance care delivery. Herein, we describe the history of germline mutation testing, epidemiology of known germline cancer mutations and their associations with childhood cancer, testing limitations, and future directions for research and clinical care.

Abstract
Purpose This study investigated changes in attitudes toward marriage and childbearing assuming a BRCA1/2 mutation carrier status among healthy, unmarried individuals in Korea. Methods A nationally representative sample of healthy, unmarried individuals aged 20–39 years was surveyed. A questionnaire on marriage and childbearing intentions was administered to the participants before and after providing them with information on BRCA1/2 mutation carriers’ breast and ovarian cancer risks and their autosomal dominant inheritance pattern. The participants were asked about their attitudes toward childbearing through preimplantation genetic diagnosis (PGD). Results Of the participants who initially wanted to marry, the assumption that they or their partners had BRCA1/2 mutation caused 25.3% to no longer want to get married and 36.2% to change their attitude from wanting to bear children to no longer wanting them. Females were more likely than males to change their attitudes toward marriage and childbearing. The participants who had negative attitudes toward genetic testing were more likely to change their attitudes regarding marriage and childbearing than those who were favorable toward both disclosure and testing. More than 50% of the participants who did not want children were willing to bear children through PGD when it was assumed that they were BRCA mutation carriers. Conclusion On the assumption of being carriers, general, young, and healthy females were more likely than males to negatively change their attitudes toward marriage and childbearing. Public education on the implications of living with mutation carriers and reproductive options may be required.

Abstract
Pancreatic cancer (PC) is a highly lethal cancer and projected to be the second leading cause of cancer death by 2030. Multigene panel testing has facilitated the identification of germline variants associated with an increased risk of PC. Precision treatment has led to improved outcomes for patients with these findings. Because of these improved outcomes as well as the implications for at-risk family members who may benefit from additional cancer screening, the NCCN recommends universal genetic testing for newly diagnosed PC patients. This review describes the most common heritable conditions associated with PC and those who may benefit from screening.

Physicians' perceptions of the factors influencing disclosure of secondary findings in tumour genomic profiling in Japan: a qualitative study. Eur J Hum Genet 2022; 30:88-94.

Abstract
Tumour genomic profiling (TGP), conducted in search of therapeutics, sometimes reveals potentially pathogenic germline variants as secondary findings (SFs). Physicians involved in TGP are often specialised in oncology and not in clinical genetics. To better utilise SFs, we explored issues physicians have during disclosure and the potential for collaborations with clinical genetics professionals. Semi-structured interviews were conducted with 14 physicians who had experience in handling outpatient TGP at designated core hospitals for cancer genomic medicine in Japan. The data were analysed thematically. The difficulties physicians experienced during informed consent (IC) included educating patients about SFs, providing detailed information on SFs, and explaining the impact of SFs on patients' family members. When SFs were detected, physicians had reservations regarding the relevance of the disclosure criteria. Confirmatory germline tests were performed using peripheral blood when tumour-only tests detected suspected SFs. Some physicians had reservations about the necessity of confirmatory tests when they did not affect the patients' treatment options. To encourage patients to receive confirmatory tests, improvements are necessary in the healthcare system, such as insurance reimbursements, education for physicians so that they can provide a better explanation to their patients, and genetic literacy of physicians and patients. The physicians offered insights into the challenges they experienced related to IC, disclosure of SFs, and expectations for active collaborations with clinical genetics professionals. Wider healthcare insurance coverage and better genetic literacy of the population may lead to more patients taking confirmatory tests when SFs are suspected.

Abstract
BACKGROUND Around 5%-10% of breast cancers are due to hereditary breast and ovarian cancer syndrome. Genetic testing is important to identify these cases, enabling the adoption of specific risk-reducing treatment strategies. OBJECTIVE To analyze the performance of genetic testing and its implications in patients with indication of genetic testing to identify hereditary predisposition to breast cancer. METHODS This is a retrospective observational cross-sectional study, including 176 patients with clinical indication of genetic testing for pathogenic variants related to breast, ovarian and pancreatic cancers (among others), managed from 1999 to 2021 in an Oncology private clinic located in the city of Teresina (PI), Brazil. RESULTS There was a predominance of female patients (98.9%) and those with a family (91.0%) and personal history (64.2%) of cancer. In the study, 102 patients (57.9%) received genetic testing. BRCA1 and BRCA2 pathogenic variants occurred in 26 cases (90%). Another three PALB2 and TP53 pathogenic variants were detected. Eleven pathogenic variant carriers (38%) underwent risk-reducing surgeries. CONCLUSIONS BRCA1/BRCA2 pathogenic variants occurred in around 25% of tested patients. Approximately 42.0% of the patients did not undergo genetic testing, despite clinical indication.

Abstract
Age is one of the most important risk factors for the development of breast cancer. Nearly a third of all breast cancer cases occur in older women (aged ≥70 years), with most cases being oestrogen receptor-positive (ER+). Such tumours are often indolent and unlikely to be the ultimate cause of death for older women, particularly when considering other comorbidities. This Review focuses on unique clinical considerations for screening, detection, and treatment regimens for older women who develop ER+ breast cancers-specifically, we focus on recent trends for de-implementation of screening, staging, surgery, and adjuvant therapies along the continuum of care. Additionally, we also review emerging basic and translational research that will further uncover the unique underlying biology of these tumours, which develop in the context of systemic age-related inflammation and changing hormone profiles. With prevailing trends of clinical de-implementation, new insights into mechanistic biology might provide an opportunity for precision medicine approaches to treat patients with well tolerated, low-toxicity agents to extend patients' lives with a higher quality of life, prevent tumour recurrences, and reduce cancer-related burdens.

Abstract
Objective Examine the risks of fractures and osteoporosis after risk-reducing bilateral salpingo-oophorectomy (RRBSO) among women with BRCA1/2 mutations. Methods In this retrospective population-based study in British Columbia, Canada, between 1996 to 2017, we compared risks of osteoporosis and fractures among women with BRCA1/2 mutations who underwent RRBSO before the age of 50 (n=329) with two age-matched groups without known mutations: 1) women who underwent bilateral oophorectomy (BO) (n=3,290); 2) women with intact ovaries who had hysterectomy or salpingectomy (n=3,290). Secondary outcomes were: having dual-energy X-ray absorptiometry (DEXA) scan, and bisphosphonates use. Results The mean age at RRBSO was 42.4 years (range, 26–49) and the median follow-up for women with BRCA1/2 mutations was 6.9 years (range, 1.1–19.9). There was no increased hazard of fractures for women with BRCA1/2 mutations (adjusted hazard ratio [aHR]=0.80; 95% confidence interval [CI]=0.56–1.14 compared to women who had BO; aHR=1.02; 95% CI=0.65–1.61 compared to women with intact ovaries). Among women who had DEXA-scan, those with BRCA1/2 mutations had higher risk of osteoporosis (aHR=1.60; 95% CI=1.00–2.54 compared to women who had BO; aHR=2.49; 95% CI=1.44–4.28 compared to women with intact ovaries). Women with BRCA1/2 mutations were more likely to get DEXA-scan than either control groups, but only 46% of them were screened. Of the women with BRCA1/2 mutations diagnosed with osteoporosis, 36% received bisphosphonates. Conclusion Women with BRCA1/2 mutations had higher risk of osteoporosis after RRBSO, but were not at increased risk of fractures during our follow-up. Low rates of DEXA-scan and bisphosphonates use indicate we can improve prevention of bone loss. BRCA mutations carriers had higher osteoporosis risk after risk-reducing bilateral salpingo-oophorectomy (RRBSO) than the groups without mutations. However, they were not at increased risk of fractures during the study period. Only 46% of BRCA mutations carriers were screened for bone loss after RRBSO. The rate of bisphosphonates use was also low.

Abstract
UNLABELLED Women with hereditary breast cancer factors are more likely to be infertile and tend to receive fertility treatments. The safety of fertility treatments that contain hormone-related medications for ovarian stimulation has gained wide attention; however, evidence of the safety of fertility treatments is limited. This study aims to assess the association between fertility treatments and the incidence rate of breast cancer in women with a family history of breast cancer or BRCA mutations. A literature search was conducted in PubMed, Cochrane Library, and Embase. Studies concerning the effect of fertility treatments on breast cancer risk in genetically susceptible women were included. The fixed and random effects models were used to estimate the summary effects. Risk Of Bias In Non-randomized Studies - of Interventions instrument was used to assess the risk of bias in the included studies. A total of 5,282 studies were screened. Five cohort studies and three case-control studies were included. Breast cancer risk was not significantly increased by fertility treatments in general genetically susceptible women [pooled odds ratio (OR) 1.18, 95% confidence interval (CI) 0.96-1.45], women with a family history of breast cancer (pooled OR 1.35, 95% CI 0.97-1.89), or women with BRCA mutations (pooled OR 1.02, 95% CI 0.74-1.4). In subgroup analyses, there was no significant increase in breast cancer risk whether in BRCA1 mutation carriers (pooled OR 1.18, 95% CI 0.81-1.72), BRCA2 mutation carriers (pooled OR 0.54, 95% CI 0.09-3.34), or in the women treated with in vitro fertilization (pooled OR 0.75, 95% CI 0.51-1.1), clomiphene citrate (pooled OR 1.07, 95% CI 0.78-1.45) or gonadotropins (pooled OR 1.32, 95% CI 0.8-2.18). This is the first meta-analysis concerning the impact of fertility treatments on breast cancer risk in genetically susceptible women. Despite the finding that fertility treatment did not significantly increase breast cancer risk in genetically susceptible women, large prospective cohorts with more detailed information are required. Further investigations are needed to explore subtypes of breast cancer, genetic background of hormone-related breast cancer, and the association between BRCA mutations and the incidence of hormone receptor-positive breast cancer.

Differences in age at diagnosis of ovarian cancer for each BRCA mutation type in Japan: optimal timing to carry out risk-reducing salpingo-oophorectomy. J Gynecol Oncol 2022; 33:e46. [PMID: 35557031 PMCID: PMC9250856 DOI: 10.3802/jgo.2022.33.e46] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2021] [Revised: 12/10/2021] [Accepted: 03/05/2022] [Indexed: 12/04/2022] Open
Abstract
Objective BRCA1 and BRCA2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) by age 40 and 45, respectively. However, the carriers have a different way of thinking about their life plan. We aimed to investigate the distribution of age at diagnosis of ovarian cancer (OC) patients to examine the optimal timing of RRSO in the carriers. Methods We examined a correlation between age at diagnosis of OC and common mutation types in 3,517 probands that received BRCA genetic testing. Among them, germline BRCA1 mutation (gBRCA1m), germline BRCA2 mutation (gBRCA2m) and germline BRCA wild-type (gBRCAwt) were found in 185, 42 and 241 OC patients, respectively. Results The average age at diagnosis of OC in gBRCA1m and gBRCA2m was 51.3 and 58.3 years, respectively, and the difference from gBRCAwt (53.8 years) was significant. The gBRCA2m carriers did not develop OC under the age of 40. The average age was 50.1 years for L63X and 52.8 years for Q934X in BRCA1, and 55.1 years for R2318X and 61.1 years for STOP1861 in BRCA2. The age at diagnosis in L63X or R2318X carriers was relatively younger than other BRCA1 or BRCA2 carriers, however their differences were not significant. With L63X and R2318X carriers, 89.4% (42/47) and 100% (7/7) of women were able to prevent the development of OC, respectively, when RRSO was performed at age 40. Conclusion There appears to be no difference in the age at diagnosis of OC depending on the type of BRCA common mutation. Further analysis would be needed. This is the first report to present the optimal timing of risk-reducing salpingo-oophorectomy for each BRCA mutation type in Japan. The average age at diagnosis of ovarian cancer (OC) in germline BRCA2 mutation (gBRCA2m) is higher than that in germline BRCA wild-type. The gBRCA2m carriers did not develop OC under the age of 40. The average age at diagnosis in L63X or R2318X carriers was relatively younger than other BRCA mutation carriers, though the differences were not significant.

Abstract
Double heterozygosity pathogenic variants in BRCA1 and BRCA2 genes are a very rare finding, particularly in non-Ashkenazi individuals. We described the first case of double heterozygosity variants in a non-Ashkenazi Argentinean woman with metachronous bilateral breast cancer. The proband is a 65-year-old female diagnosed with invasive ductal carcinoma in the left breast at 45 years old and invasive carcinoma in the right breast at 65 years old. She underwent a multi-gene panel testing indicating the presence of two concurrent heterozygous germline deleterious variants NM_007300.4(BRCA1):c.4201C>T (p.Gln1401Ter), and NM_000059.3(BRCA2):c.5146_5149del (p.Tyr1716fs). . The patient's son (40 years-old) was found to have the inherited pathogenic variant in BRCA2 gene. There are few reports of double heterozygosity variants in BRCA1 and BRCA2 genes in Latin America. The two pathogenic variants identified in our patient have not been described together so far.

Abstract
PURPOSE Family cancer history is an important component of genetic testing guidelines that estimate which patients with breast cancer are most likely to carry a germline pathogenic variant (PV). However, we do not know whether more extensive family history is differentially associated with PVs in specific genes. METHODS All women diagnosed with breast cancer in 2013-2017 and reported to statewide SEER registries of Georgia and California were linked to clinical genetic testing results and family history from two laboratories. Family history was defined as strong (suggestive of PVs in high-penetrance genes such as BRCA1/2 or TP53, including male breast, ovarian, pancreatic, sarcoma, or multiple female breast cancers), moderate (any other cancer history), or none. Among established breast cancer susceptibility genes (ATM, BARD1, BRCA1, BRCA2, CDH1, CHEK2, NF1, PALB2, PTEN, RAD51C, RAD51D, and TP53), we evaluated PV prevalence according to family history extent and breast cancer subtype. We used a multivariable model to test for interaction between affected gene and family history extent for ATM, BRCA1/2, CHEK2, and PALB2. RESULTS A total of 34,865 women linked to genetic results. Higher PV prevalence with increasing family history extent (P < .001) was observed only with BRCA1 (3.04% with none, 3.22% with moderate, and 4.06% with strong history) and in triple-negative breast cancer with PALB2 (0.75% with none, 2.23% with moderate, and 2.63% with strong history). In a multivariable model adjusted for age and subtype, there was no interaction between family history extent and PV prevalence for any gene except PALB2 (P = .037). CONCLUSION Extent of family cancer history is not differentially associated with PVs across established breast cancer susceptibility genes and cannot be used to personalize genes selected for testing.

Advances in the Aetiology & Endoscopic Detection and Management of Early Gastric Cancer. Cancers (Basel) 2021; 13:cancers13246242. [PMID: 34944861 PMCID: PMC8699285 DOI: 10.3390/cancers13246242] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 12/06/2021] [Accepted: 12/10/2021] [Indexed: 12/24/2022] Open
Abstract
Simple Summary Gastric adenocarcinoma has remained a highly lethal disease. Awareness and recognition of preneoplastic conditions (including gastric atrophy and intestinal metaplasia) using high-resolution white-light endoscopy as well as chromoendoscopy is therefore essential. Helicobacter pylori, a class I carcinogen, remains the main contributor to the development of sporadic distal gastric neoplasia. Management of early gastric neoplasia with endoscopic resections should be in line with standard indications. A multidisciplinary approach to any case of an early gastric neoplasia is imperative. Hereditary forms of gastric cancer require a tailored approach and individua-lized surveillance. Abstract The mortality rates of gastric carcinoma remain high, despite the progress in research and development in disease mechanisms and treatment. Therefore, recognition of gastric precancerous lesions and early neoplasia is crucial. Two subtypes of sporadic gastric cancer have been recognized: cardia subtype and non-cardia (distal) subtype, the latter being more frequent and largely associated with infection of Helicobacter pylori, a class I carcinogen. Helicobacter pylori initiates the widely accepted Correa cascade, describing a stepwise progression through precursor lesions from chronic inflammation to gastric atrophy, gastric intestinal metaplasia and neoplasia. Our knowledge on He-licobacter pylori is still limited, and multiple questions in the context of its contribution to the pathogenesis of gastric neoplasia are yet to be answered. Awareness and recognition of gastric atrophy and intestinal metaplasia on high-definition white-light endoscopy, image-enhanced endoscopy and magnification endoscopy, in combination with histology from the biopsies taken accurately according to the protocol, are crucial to guiding the management. Standard indications for endoscopic resections (endoscopic mucosal resection and endoscopic submucosal dissection) of gastric dysplasia and intestinal type of gastric carcinoma have been recommended by multiple societies. Endoscopic evaluation and surveillance should be offered to individuals with an inherited predisposition to gastric carcinoma.

Front Mol Biosci 2021; 8:762741. [PMID: 34869593 PMCID: PMC8640082 DOI: 10.3389/fmolb.2021.762741] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 10/25/2021] [Indexed: 11/30/2022] Open
Abstract
Background: The homologous recombination (HR) pathway defects in cancers induced abrogation of cell cycle checkpoints, resulting in the accumulation of DNA damage, mitotic catastrophe, and cell death. Cancers with BRCA1/2 loss and other accumulation of similar genomic scars resulting in HRD displayed increased sensitivity to chemotherapy. Our study aimed to explore HRD score genetic mechanisms and subsequent clinical outcomes in human cancers, especially ovarian cancer. Methods: We analyzed TCGA data of HRD score in 33 cancer types and evaluated HRD score distribution and difference among tumor stages and between primary and recurrent tumor tissues. A weighted gene co-expression network analysis (WGCNA) was performed to identify highly correlated genes representing essential modules contributing to the HRD score and distinguish the hub genes and significant pathways. We verified HRD status predicting roles in patients’ overall survival (OS) with univariate and multivariate Cox regression analyses and built the predicting model for patient survival. Results: We found that the HRD score increased with the rise in tumor stage, except for stage IV. The HRD score tended to grow up higher in recurrent tumor tissue than in their primary counterparts (p = 0.083). We constructed 15 co-expression modules with WGCNA, identified co-expressed genes and pathways impacting the HRD score, and concluded that the HRD score was tightly associated with tumor cells replication and proliferation. A combined HRD score ≥42 was associated with shorter OS in 33 cancer types (HR = 1.010, 95% CI: 1.008–1.011, p < 0.001). However, in ovarian cancer, which ranked the highest HRD score among other cancers, HRD ≥42 cohort was significantly associated with longer OS (HR = 0.99, 95% CI: 0.98–0.99, p < 0.0001). We also built a predicting model for 3 and 5 years survival in HGSC patients. Conclusion: A quantitative HRD score representing the accumulated genomic scars was dynamically increasing in proliferating tumor cells since the HRD score was tightly correlated to tumor cell division and replication. We highlighted HRD score biomarker role in prognosis prediction of ovarian cancer.

Gastric cancer genetic predisposition and clinical presentations: Established heritable causes and potential candidate genes. Eur J Med Genet 2021; 65:104401. [PMID: 34871783 DOI: 10.1016/j.ejmg.2021.104401] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Revised: 11/10/2021] [Accepted: 11/28/2021] [Indexed: 12/12/2022]
Abstract
Tumour risk syndromes (TRS) are characterized by an increased risk of early-onset cancers in a familial context. High cancer risk is mostly driven by loss-of-function variants in a single cancer-associated gene. Presently, predisposition to diffuse gastric cancer (DGC) is explained by CDH1 and CTNNA1 pathogenic and likely pathogenic variants (P/LP), causing Hereditary Diffuse Gastric Cancer (HDGC); while APC promoter 1B single nucleotide variants predispose to Gastric Adenocarcinoma and Proximal Polyposis of the Stomach (GAPPS). Familial Intestinal Gastric Cancer (FIGC), recognized as a GC-predisposing disease, remains understudied and genetically unsolved. GC can also occur in the spectrum of other TRS. Identification of heritable causes allows defining diagnostic testing criteria, helps to clinically classify GC families into the appropriate TRS, and allows performing pre-symptomatic testing identifying at-risk individuals for downstream surveillance, risk reduction and/or treatment. However, most of HDGC, some GAPPS, and most FIGC patients/families remain unsolved, expecting a heritable factor to be discovered. The missing heritability in GC-associated tumour risk syndromes (GC-TRS) is likely explained not by a single major gene, but by a diversity of genes, some, predisposing to other TRS. This would gain support if GC-enriched small families or apparently isolated early-onset GC cases were hiding a family history compatible with another TRS. Herein, we revisited current knowledge on GC-TRS, and searched in the literature for individuals/families bearing P/LP variants predisposing for other TRS, but whose probands display a clinical presentation and/or family history also fitting GC-TRS criteria. We found 27 families with family history compatible with HDGC or FIGC, harbouring 28 P/LP variants in 16 TRS-associated genes, mainly associated with DNA repair. PALB2 or BRCA2 were the most frequently mutated candidate genes in individuals with family history compatible with HDGC and FIGC, respectively. Consolidation of PALB2 and BRCA2 as HDGC- or FIGC-associated genes, respectively, holds promise and worth additional research. This analysis further highlighted the influence, that proband's choice and small or unreported family history have, for a correct TRS diagnosis, genetic screening, and disease management. In this review, we provide a rational for identification of particularly relevant candidate genes in GC-TRS.

Abstract
Young women with breast cancer (YWBC) account for a variable proportion of patients diagnosed with breast cancer around the globe, with a higher prevalence in resource-limited settings than in high-income countries. This group represents a unique population that warrants special attention due to specific biological considerations and age-specific supportive care issues. This review aims to explore existing knowledge regarding YWBC's needs, particularly in resource-restricted settings. To date, scarce information regarding the care of YWBC in resource-constrained countries is available, with most reports describing suboptimal care in terms of survivorship needs. Health care providers should implement actions to improve endocrine treatment adherence, referrals for fertility counseling and preservation, contraceptive use compliance, timely body image and sexual function interventions, comprehensive genetic risk assessments, and early quality of life and psychosocial health interventions. While high costs act as a barrier for optimal care in resource-limited settings, improving patient education represents a promising and cost-effective solution to improve patient care. Future research on developing tailored educational resources for YWBC in resource-limited settings should be considered a priority.

Abstract
Evidence suggesting that high-grade serous ovarian cancers originate in the fallopian tubes has led to the emergence of opportunistic salpingectomy (OS) as an approach to reduce ovarian-cancer risk. In the U.S., some national societies now recommend OS in place of tubal ligation for sterilization or during a benign hysterectomy in average-risk women. However, limited data exist on the dissemination of OS in clinical practice. We examined the uptake and predictors of OS in a nationwide sample of inpatient and outpatient claims (N = 48,231,235) from 2010 to 2017. Incidence rates of OS were calculated, and an interrupted time-series analysis was used to quantify changes in rates before (2010-2013) and after (2015-2017) national guideline release. Predictors of OS use were examined using Poisson regression. From 2010 to 2017, the age-adjusted incidence rate of OS for sterilization and OS during hysterectomy increased 17.8-fold [95% confidence interval (CI), 16.2-19.5] and 7.6-fold (95% CI, 5.5-10.4), respectively. The rapid increase (age-adjusted increase in quarterly rates of between 109% and 250%) coincided with the time of national guideline release. In multivariable-adjusted analyses, OS use was more common in young women and varied significantly by geographic region, rurality, family history/genetic susceptibility, surgical indication, inpatient/outpatient setting, and underlying comorbidities. Similar differences in OS uptake were noted in analyses limited to women with a family history/genetic susceptibility to breast/ovarian cancer. Our results highlight significant differences in OS uptake in both high- and average-risk women. Defining subsets of women who would benefit most from OS and identifying barriers to equitable OS uptake is needed. PREVENTION RELEVANCE: Opportunistic salpingectomy for ovarian-cancer risk reduction has been rapidly adopted in the U.S., with significant variation in uptake by demographic and clinical factors. Studies examining barriers to opportunistic salpingectomy access and the long-term effectiveness and potential adverse effects of opportunistic salpingectomy are needed.

Abstract
Preventive population genomics offers the prospect of population stratification for targeting screening and prevention and tailoring care to those at greatest risk. Within cancer, this approach is now within reach, given our expanding knowledge of its heritable components, improved ability to predict risk, and increasing availability of effective preventive strategies. Advances in technology and bioinformatics has made population-testing technically feasible. The BRCA model provides 30 years of insight and experience of how to conceive of and construct care and serves as an initial model for preventive population genomics. Population-based BRCA-testing in the Jewish population is feasible, acceptable, reduces anxiety, does not detrimentally affect psychological well-being or quality of life, is cost-effective and is now beginning to be implemented. Population-based BRCA-testing and multigene panel testing in the wider general population is cost-effective for numerous health systems and can save thousands more lives than the current clinical strategy. There is huge potential for using both genetic and non-genetic information in complex risk prediction algorithms to stratify populations for risk adapted screening and prevention. While numerous strides have been made in the last decade several issues need resolving for population genomics to fulfil its promise and potential for maximizing precision prevention. Healthcare systems need to overcome significant challenges associated with developing delivery pathways, infrastructure expansion including laboratory services, clinical workforce training, scaling of management pathways for screening and prevention. Large-scale real world population studies are needed to evaluate context specific population-testing implementation models for cancer risk prediction, screening and prevention.

Abstract
More than 1.5 million individuals in the United States identify as transgender. Transgender individuals have lower rates of health care utilization and higher rates of health care discrimination than cisgender patients. With a growing interest in providing comprehensive and compassionate care to the transgender community, there has been a concurrent increase in research on transgender health. However, lack of long-term data limits understanding the effects of hormone therapy on cancer risk factors in this population. This is particularly relevant for patients with hormonally mediated cancers and those at elevated risk from hereditary breast and ovarian cancer syndromes. Few cancer-screening and management guidelines currently exist for this population. Specific practices guided by the nuances of gender identity and gender-affirming care are essential to improve clinical management and to avoid further alienating a population that is already marginalized from the health care system. This commentary summarizes screening, management, and surveillance strategies devised for cisgender patients to offer corresponding recommendations tailored for transgender BRCA mutation carriers. In doing so, it highlights critical unanswered questions pertaining to the care of these patients. To address these questions, we must prioritize this population and adopt more inclusive frameworks in medicine and research.

Abstract
OBJECTIVE To provide latest findings of Urologic Oncology on prostate, kidney, and bladder cancer, and analyze its impact on clinical practice as well as future schemes in the medium- and long-term. METHODS This document reviews the abstracts on Uro-Oncology presented at the 2020 Congresses (EUA, AUA, ASCO, ESMO and ASTRO), the publications with the highest impact and especially the new lines of development and progress in Uro-Oncology evaluated by the OncoForum committee. RESULTS The use of prostate-specific membrane antigen (PSMA) radioligands in the diagnosis of prostate cancer may have great potential and utility in the coming years due to their improved sensitivity and specificity. The genetic characterization of the tumor is important at both, germline and somatic levels, due to the significant role of BRCA2 mutations regarding risk. The cohort multiple randomised controlled trial is the most suitable study design at the genitourinary cancer level. The application of big data will lead to process improvements, savings in healthcare costs, and an empowerment of real-life studies through ease of data comparison, management, and storage. CONCLUSIONS The use of new diagnostic techniques with PSMA ligands will provide a more comprehensive diagnostic modality, increase the number of studies about tumor genetic profiling, and enhance their quality. The practical application of artificial intelligence will improve the treatment genitourinary cancer.

Abstract
Breast cancer is the most common cancer among females worldwide with rising incidence. In the United States, screening mammography and advances in therapy have lowered mortality by 41% since 1990. Screening mammography is supported by randomized control trials (RCT), observational studies, and computer model data. Digital breast tomosynthesis is a new technology that addresses limitations in mammography resulting from overlapping breast tissue, improving its sensitivity and specificity. Patients at high risk for breast cancer include those with a ≥20% lifetime risk, high-risk germline mutation, or history of thoracic radiation treatment between 10-30 years of age. Such patients are recommended to undergo annual screening mammography and adjunctive annual screening breast MRI. Patients unable to undergo MRI may undergo whole breast ultrasound or contrast-enhanced mammography. Pregnant and lactating patients at average risk for breast cancer are recommended to undergo age-appropriate screening mammography.

Abstract
Purpose The aim of the study was to evaluate the clinical implication of multigene panel testing of beyond BRCA genes in Korean patients with BRCA1/2 mutation-negative breast cancer. Materials and Methods Between 2016 and 2019, a total of 700 BRCA1/2 mutation-negative breast cancer patients received comprehensive multigene panel testing and genetic counseling. Among them, 347 patients completed a questionnaire about cancer worry, genetic knowledge, and preference for the method of genetic tests during pre- and post-genetic test counseling. The frequency of pathogenic and likely pathogenic variants (PV/LPV) were analyzed. Results At least one PV/LPV of 26 genes was found in 76 out of 700 patients (10.9 %). The rate for PV/LPV was 3.4% for high-risk genes (17 PALB2, 6 TP53, and 1 PTEN). PV/LPVs of clinical actionable genes for breast cancer management, high-risk genes and other moderate-risk genes such as ATM, BARD1, BRIP, CHEK2, NF1, and RAD51D, were observed in 7.4%. Patients who completed the questionnaire showed decreased concerns about the risk of additional cancer development (average score, 4.21 to 3.94; p < 0.001), influence on mood (3.27 to 3.13; p < 0.001), influence on daily functioning (3.03 to 2.94; p=0.006); and increased knowledge about hereditary cancer syndrome (66.9 to 68.8; p=0.025) in post-test genetic counseling. High cancer worry scales (CWSs) were associated with age ≤ 40 years and the identification of PV/LPV. Low CWSs were related to the satisfaction of the counselee. Conclusion Comprehensive multigene panel test with genetic counseling is clinically applicable. It should be based on interpretable genetic information, consideration of potential psychological consequences, and proper preventive strategies.

Abstract
Genetic testing offers providers a potentially life saving tool for identifying and intervening in high-risk individuals. However, disparities in receipt of genetic testing have been consistently demonstrated and undoubtedly have significant implications for the populations not receiving the standard of care. If correctly used, there is the potential for genetic testing to play a role in decreasing health disparities among individuals of different races and ethnicities. However, if genetic testing continues to revolutionize cancer care while being disproportionately distributed, it also has the potential to widen the existing mortality gap between various racial and ethnic populations.
