Abstract
One to 3% of gastric cancers are secondary to genetic predisposition, notably hereditary diffuse gastric cancers (HDGC) caused by CDH1 gene mutations. According to French recommendations, in case of CDH1 gene mutation, a prophylactic total gastrectomy should be performed between 20 and 30 years old. This gastrectomy should remove all the gastric mucosa at both extremities (duodenal and esophageal sides). Histopathological examinations of prophylactic total gastrectomies in asymptomatic CDH1-mutated patients reveal microscopic foci of diffuse-type cancer in 90 to 100% of cases. Lymph node involvement and lympho-vascular invasion are extremely rare, justifying the use of a D1-only lymphadenectomy. In the context of prophylaxis, limited lymphadenectomy and the development of minimally invasive oesogastric surgery, the minimally invasive approach might be the preferred approach, in expert centers. Surgical outcomes seem to be similar to those after gastrectomy for cancer. Prophylactic total gastrectomy is the cornerstone of CGDH management, associated with multidisciplinary follow-up and mammary surveillance in women.

Abstract
BACKGROUND Gastric cancer is one of the most common malignant tumors in the digestive system in China. Few comprehensive practice guidelines for early gastric cancer in China are currently available. Therefore, we created the Chinese national clinical practice guideline for the prevention, diagnosis, and treatment of early gastric cancer. METHODS This clinical practice guideline (CPG) was developed in accordance with the World Health Organization's recommended process and with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) in assessing evidence quality. We used the Evidence to Decision framework to formulate clinical recommendations to minimize bias and increase transparency in the CPG development process. We used the Reporting Items for practice Guidelines in HealThcare (RIGHT) statement and the Appraisal of Guidelines for Research and Evaluation II (AGREE II) as reporting and conduct guidelines to ensure completeness and transparency of the CPG. RESULTS This CPG contains 40 recommendations regarding the prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer based on available clinical studies and guidelines. We provide recommendations for the timing of Helicobacter pylori eradication, screening populations for early gastric cancer, indications for endoscopic resection and surgical gastrectomy, follow-up interval after treatment, and other recommendations. CONCLUSIONS This CPG can lead to optimum care for patients and populations by providing up-to-date medical information. We intend this CPG for widespread adoption to increase the standard of prevention, screening, diagnosis, treatment, and follow-up of early gastric cancer; thereby, contributing to improving national health care and patient quality of life.

Abstract
PURPOSE Risk-reducing surgery for cancer prevention in solid tumors is a pressing clinical topic because of the increasing availability of germline genetic testing. We examined the short- and long-term outcomes of risk-reducing total gastrectomy (RRTG) and its lesser-known impacts on health-related quality of life (QOL) in individuals with hereditary diffuse gastric cancer syndrome. METHODS Individuals who underwent RRTG as part of a single-institution natural history study of hereditary gastric cancers were examined. Clinicopathologic details, acute and chronic operative morbidity, and health-related QOL were assessed. Validated questionnaires were used to determine QOL scores and psycho-social-spiritual measures of healing. RESULTS One hundred twenty-six individuals underwent RRTG because of a pathogenic or likely pathogenic germline CDH1 variant between October 2017 and December 2021. Most patients (87.3%; 110/126) had pT1aN0 gastric carcinoma with signet ring cell features on final pathology. Acute (<30 days) postoperative major morbidity was low (5.6%; 7/126) and nearly all patients (98.4%) lost weight after total gastrectomy. At 2 years after gastrectomy, 94% (64/68) of patients exhibited at least one chronic complication (ie, bile reflux, dysphagia, and micronutrient deficiency). Occupation change (23.5%), divorce (3%), and alcohol dependence (1.5%) were life-altering consequences attributed to total gastrectomy by some patients. In patients with a median follow-up of 24 months, QOL scores decreased at 1 month after gastrectomy and returned to baseline by 6-12 months. CONCLUSION RRTG is associated with life-changing adverse events that should be discussed when counseling patients with CDH1 variants about gastric cancer prevention. The risks of cancer-prevention surgery should not only be judged in the context of likelihood of death due to disease if left untreated, but also based on the real consequences of organ removal.

Cancers (Basel) 2024; 16:473. [PMID: 38339225 PMCID: PMC10854827 DOI: 10.3390/cancers16030473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 12/23/2023] [Accepted: 12/25/2023] [Indexed: 02/12/2024] Open
Abstract
Hereditary diffuse gastric cancer (HDGC) is an autosomal-dominant syndrome associated with early onset diffuse gastric cancer. Definitive treatment is prophylactic total gastrectomy (PTG) associated with significant morbidity. Studies published from January 2000 to December 2022 reporting clinical, histopathological or health-related quality of life outcomes in HDGC patients undergoing PTG were identified. The study quality was assessed by the "Newcastle-Ottawa scale". Of the 257 articles screened, 21 were selected. A total of 353 patients were examined in 15 studies that reported surgical outcomes. The median age was 42 years old. The median major complication and mortality rates were 19.2% and 0.3%, respectively. The most common complications were wound infection at 4.8% followed by anastomotic leak and pulmonary complications at 4.5% each. Following PTG, 88.6% of patients had early lesions amongst 414 patients. The mean/median number of signet ring cell carcinoma foci in the gastrectomy specimens was from 2 to 78. All cases were stage 1 with no lymph node involvement. There was a wide range of psychosocial effects following PTG closely related to the physical symptoms. It is imperative for patients to receive comprehensive preoperative counselling to make an informed decision and be followed up under the care of a multidisciplinary team.

Abstract
BACKGROUND CDH1 gene mutations are the leading etiology of hereditary diffuse gastric cancer with cumulative lifetime risk ranging up to 83%. Prophylactic total gastrectomy (PTG) is, therefore, recommended for CDH1 carriers. A laparoscopic approach may reduce operative risk versus an open operation, thus leading more patients with CDH1 mutations to pursue PTG prior to cancer development. However, more experience and oncologic outcome data are needed for a laparoscopic approach and indicated lymphadenectomy. METHODS A retrospective descriptive cohort study of adult patients with CDH1 mutations who underwent laparoscopic PTG with D1 lymphadenectomy between 2012 and 2022 was conducted at a single institution. All patients had preoperative EGD screening, and those with visible tumor lesions on surveillance EGD were excluded and not considered prophylactic. Demographics, family history, pathology, and operative course were obtained. Outcomes included complications, readmission, and postoperative weight change. RESULTS Among 23 patients, median age was 48 years (IQR 37, 53) and 15 (65%) were female. Family history for gastric and/or lobular breast cancer was present in 22 (96%) patients. The median [IQR] time from positive genetic testing to PTG was 347 days [140, 625]. Pathologic evaluation showed five (22%) patients with foci of gastric cancer on pre-operative EGD biopsies, 10 (44%) in resected stomach specimens. All lymph nodes were negative. To address early postoperative complications, EJ anastomotic technique changed from EEA to GIA over the course of the study and feeding jejunostomy was no longer placed during PTG with minimal change in postoperative weight loss. CONCLUSIONS This is the largest series, spanning 10 years at a single institution, dedicated solely to a laparoscopic approach for risk-reducing PTG. A laparoscopic approach with limited lymphadenectomy resulted in acceptable surgical and oncologic outcomes. Despite no visible cancer, over half of our patients had foci of early gastric cancer. Therefore, CDH1 carriers should consider laparoscopic PTG.

Abstract
BACKGROUND Gastrectomy with lymphadenectomy in combination with perioperative chemotherapy is the cornerstone of modern curative treatment for gastric adenocarcinoma. The primary objective of this study was to assess the influence of textbook outcome, postoperative complications, and readmission on survival in patients who underwent gastric cancer surgery. METHODS Consecutive patients who underwent curative and prophylactic gastric resections from 2014 to 2022 at Christchurch Hospital were identified from the hospital database. Multivariable analyses were performed to assess risk factors for each postoperative outcome. A survival analysis was performed to evaluate the influence of these outcomes on overall survival. RESULTS Seventy-seven patients underwent a gastric resection during the study period. Thirteen were prophylactic resections for E-cadherin gene mutations and 64 were for malignancy. The overall postoperative complication rate was 34%, with an anastomotic leak rate of 8% (n = 6). The 30-day readmission rate, 30-day mortality rate and 90-day mortality rate were 17%, 1%, and 5% respectively. No sociodemographic differences were identified in each outcome. An increasing day-4 CRP trajectory was observed in patients with an anastomotic leak. Postoperative complications and nodal disease were independent prognostic factors for reduced survival. CONCLUSIONS Textbook outcome, postoperative complications, and readmission are validated quality performance indicators of gastric cancer surgery. Postoperative complications are associated with poor overall survival independent of severity or type. The underlying mechanisms of this influence remain elusive. The aggressive biology of gastric cancer, combined with the surgical morbidity and its negative influence on survival, highlights the importance of ongoing quality improvement.

Abstract
OBJECTIVE Here, we characterize differences in the genetic and microbial profiles of GC in patients of African (AFR), European, and Asian ancestry. BACKGROUND Gastric cancer (GC) is a heterogeneous disease with clinicopathologic variations due to a complex interplay of environmental and biological factors, which may affect disparities in oncologic outcomes.. METHODS We identified 1042 patients with GC with next-generation sequencing data from an institutional Integrated Mutation Profiling of Actionable Cancer Targets assay and the Cancer Genomic Atlas group. Genetic ancestry was inferred from markers captured by the Integrated Mutation Profiling of Actionable Cancer Targets and the Cancer Genomic Atlas whole exome sequencing panels. Tumor microbial profiles were inferred from sequencing data using a validated microbiome bioinformatics pipeline. Genomic alterations and microbial profiles were compared among patients with GC of different ancestries. RESULTS We assessed 8023 genomic alterations. The most frequently altered genes were TP53 , ARID1A , KRAS , ERBB2 , and CDH1 . Patients of AFR ancestry had a significantly higher rate of CCNE1 alterations and a lower rate of KRAS alterations ( P < 0.05), and patients of East Asian ancestry had a significantly lower rate of PI3K pathway alterations ( P < 0.05) compared with other ancestries. Microbial diversity and enrichment did not differ significantly across ancestry groups ( P > 0.05). CONCLUSIONS Distinct patterns of genomic alterations and variations in microbial profiles were identified in patients with GC of AFR, European, and Asian ancestry. Our findings of variation in the prevalence of clinically actionable tumor alterations among ancestry groups suggest that precision medicine can mitigate oncologic disparities.

Abstract
Worldwide, gastric cancer results in significant morbidity and mortality. Ten per cent of patients with gastric cancer have a strong family history of the disease. CDH1 (E-cadherin) has been identified as a key gene whose mutation leads to hereditary diffuse gastric cancer. We overviewed 33 articles with prophylactic total gastrectomy and assessed the outcomes and benefits. Families with mutations in CDH1 may benefit from early prophylactic total gastrectomy. Dr Mark Duncan has applied his experience as a high-volume gastric cancer surgeon to treat not only individual patients, but several generations of patients within a family. This use of prophylactic total gastrectomy is well tolerated by patients and prevents the future development of gastric cancer.

Abstract
Germline pathogenic variants in E-cadherin (CDH1) confer high risk of developing lobular breast cancer and diffuse gastric cancer (DGC). The cumulative risk of DGC in CDH1 carriers has been recently reassessed (from 40-83% by age 80 to 25-42%) and varies according to the presence and number of gastric cancers in the family. As there is no accurate estimate of the risk of gastric cancer in families without DGC, the International Gastric Cancer Linkage Consortium recommendation is not straightforward: prophylactic gastrectomy or endoscopic surveillance should be proposed for these families. The inclusion of CDH1 in constitutional gene panels for hereditary breast and ovarian cancer and for gastrointestinal cancers, recommended by the French Genetic and Cancer Consortium in 2018 and 2020, leads to the identification of families with lobular cancer without DGC but also to incidental findings of pathogenic variants. Management of CDH1 carriers in case of incidental findings is complex and causes dilemmas for both patients and providers. We report eleven families (47 CDH1 carriers) from our oncogenetic department specialized in breast and ovarian cancer, including four incidental findings. We confirmed that six families did not have diffuse gastric cancer in their medical records. We discuss the management of the risk of diffuse gastric cancer in Hereditary Lobular Breast Cancer (HLBC) through a family of 11 CDH1 carriers where foci were identified in endoscopic surveillance. We also report a new colon signet ring cancer case in a CDH1 carrier, a rare aggressive cancer included in CDH1-related malignancies.

Risk-reducing surgery for individuals with cancer-predisposing germline pathogenic variants and no personal cancer history: a review of current UK guidelines. Br J Cancer 2023; 129:383-392. [PMID: 37258796 PMCID: PMC10403612 DOI: 10.1038/s41416-023-02296-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 04/18/2023] [Accepted: 04/21/2023] [Indexed: 06/02/2023] Open
Abstract
Identifying healthy carriers of germline pathogenic variants in high penetrance cancer susceptibility genes offers the potential for risk-reducing surgery. The NHS England National Genomic Test Directory offers germline and somatic testing to patients with certain cancers or rare and inherited diseases, or, in some cases, to their relatives. This review summarises current UK guidelines for risk-reducing surgical interventions available for individuals with no personal history of cancer, who are determined to carry germline pathogenic variants. An electronic literature search of NICE guidelines and PubMed citable articles was performed. NICE guidelines are available for bilateral mastectomy and are currently in development for risk-reducing bilateral salpingo-oophorectomy. Guidelines developed with affiliation to, or through relevant British Surgical Societies or international consensus, are available for risk-reducing hysterectomy, polypectomy, gastrectomy, and thyroidectomy. There is a disparity in the development and distribution of national guidelines for interventions amongst tumour types. Whilst we are focusing on UK guidelines, we anticipate they will be relevant much more generally and so of interest to a wider audience including where there are no national guidelines to refer to. We suggest that, as genetic testing becomes rapidly more accessible, guideline development for interventions should be more closely aligned to those for testing.

Abstract
The common use of genetic testing has reinvigorated discussions surrounding enhanced cancer surveillance, chemoprevention, and preventive surgery strategies due to increasing recognition of pathogenic germline genetic variants. Prophylactic surgery for hereditary cancer syndromes can significantly reduce the risk of developing cancer. Hereditary diffuse gastric cancer (HDGC), characterized by high penetrance and an autosomal dominant inheritance pattern, is causally linked to germline mutations in the CDH1 tumor suppressor gene. Risk-reducing total gastrectomy is currently recommended in patients with pathogenic and likely pathogenic CDH1 variants; however, the physical and psychosocial sequelae of complete stomach removal are substantial and need to be investigated further. In this review, we address the risks and benefits of prophylactic total gastrectomy for HDGC in the context of prophylactic surgery for other highly penetrant cancer syndromes.

Abstract
Due to the increasing research into familial clustering of cancer entities, more and more genes are being identified in which mutations explain this clustering. Mutations in the cadherin 1 (CDH1) and catenin alpha 1 (CTNNA1) genes are considered to be causative for the occurrence of hereditary diffuse gastric cancer. Those affected show an incidence of gastric cancer of around 40% up to the age of 80 years and affected women show an incidence of 55% for the occurrence of lobular breast cancer. In 2020 updated international guidelines were published for the clinical management of patients with hereditary diffuse gastric cancer. When the specific test criteria are fulfilled, patients should undergo genetic testing for mutations in the CDH1 and CTNNA1 genes. In cases of the familial occurrence of diffuse gastric cancer and detection of a pathological mutation, a prophylactic total gastrectomy with D1 lymphadenectomy is recommended. Alternatively, or when pathological mutations are not detected, a gastroscopy should be performed annually with targeted and random biopsies. The occurrence of lobular breast cancer should be monitored annually by magnetic resonance imaging (MRI) from the age of 30 years onwards. A bilateral mastectomy for risk reduction should be discussed in a multidisciplinary setting.

Abstract
Hereditary diffuse gastric cancer (HDGC) is a dominantly inherited cancer syndrome characterized by a high incidence of diffuse gastric cancer (DGC) and lobular breast cancer (LBC). HDGC is caused by germline mutations in 2 genes involved in the epithelial adherens junction complex, CDH1 and CTNNA1. We discuss the genetics of HDGC and the variability of its clinical phenotype, in particular the variable penetrance of advanced DGC and LBC, both within and between families. We review the pathology of the disease, the mechanism of tumor initiation, and its natural history. Finally, we describe current best practice for the clinical management of HDGC, including emerging genetic testing criteria for the identification of new families, methods for endoscopic surveillance, the complications associated with prophylactic surgery, postoperative quality of life, and the emerging field of HDGC chemoprevention.

Abstract
The occurrence of gastric cancer has been associated with an increased risk of lobular breast tumors in a subset of patients harboring selected germline mutations. Among all, the germline alteration of the gene coding for E-Cadherin (CDH1) was associated with an increased risk of gastric cancer diffuse-histotype and lobular breast cancer. However, the risk assessment of breast neoplasms and the role of multiple prophylactic procedures in these patients has never been systematically addressed. In addition, the performance of the common screening procedures for lobular breast cancer like mammography is suboptimal. Therefore, recalling the need for a better articulation of the patient-centered strategies of surveillance for individuals with germline CDH1 and other similar alterations, to offer comprehensive approaches for prevention, early diagnosis, and treatment. Accordingly, this chapter aims to discuss the value and the role of integrated oncological care in the era of oncology sub-specializations. Additionally, it sheds light on how the harmonization across the health providers can enhance patient care in this setting.

Surgery for Hereditary Diffuse Gastric Cancer: Long-Term Outcomes. Cancers (Basel) 2022; 14:cancers14030728.

Abstract
Simple Summary This study reports the long-term results of total gastrectomy for patients with a family history of gastric cancer and CDH1 gene mutations that predispose to hereditary diffuse gastric cancer (HDGC). Total gastrectomy was performed in 8 symptomatic patients and 22 asymptomatic patients of whom only 3 had HDGC diagnosed preoperatively. 7 of 8 symptomatic had metastatic lymph nodes with cancer. 21 of 22 asymptomatic patients had gastric cancer localized to the stomach and each was cured. 15 of those patients had 9-year follow-up. Each had significant weight loss (23% body weight) with a normal body mass index, 40% had bile reflux controlled with medication, and each returned to work and said they would do it again. Long-term quality of life following gastrectomy was acceptable. Abstract Introduction: Gastric cancer is inherited as an autosomal dominant condition in hereditary diffuse gastric cancer (HDGC). The gene associated with HDGC is an E-cadherin gene CDH1. At the time of initiation of this study, it was estimated that 70% of patients who inherited the CDH1 gene mutation would develop gastric cancer. We hypothesized that the rate of signet ring cell cancer in asymptomatic patients with CDH1 mutations may be higher than anticipated and that the surgery could be conducted with acceptable short-term and long-term complications suggesting that the quality of life with the surgery is acceptable. Methods: We prospectively studied the role of total gastrectomy in symptomatic and asymptomatic patients with CDH1 mutations. A total of 43 patients with mutations of the CDH1 gene were studied prospectively, including 8 with symptoms and 35 without symptoms. Total gastrectomy was recommended to each. Quality of life was assessed in patients who underwent prophylactic gastrectomy. Proportions are compared with Fisher’s exact test. Results: In total, 13 (30%) asymptomatic patients declined surgery. Total gastrectomy was performed in 8 symptomatic patients and 22 asymptomatic patients of whom only 3 asymptomatic patients (14%) had endoscopically proven signet ring cell cancer preoperatively, while 21 of 22 (95%) had it on final pathology (p = 0.05). Each asymptomatic patient was T1, N0, while seven out of eight symptomatic patients had T3-T4 tumors and six had positive lymph nodes. None had operative complications or operative death. The median follow-up was 7 years. Five (63%) symptomatic patients died, while only one (95%) prophylactic patient died of a non-gastric cancer- or surgery-related issue (p = 0.05). A total of 15 prophylactic patients had long-term follow-up. Each had significant weight loss (mean 23%) but all had a normal body mass index. In total, 40% had bile reflux gastritis controlled with sucralfate. Each returned to work and, if given the choice, said that they would undergo the surgery again. Conclusions: Total gastrectomy is indicated for patients who have an inherented CDH1 mutation. Endoscopic screening is not reliable for diagnosing signet ring cell stomach cancer. If patients wait for symptoms, they will have a more advanced disease and significantly reduced survival. Operative complications of prophylactic gastrectomy are minimal, and long-term quality of life is acceptable.

Abstract
Inactivating germline variants in the CDH1 tumor suppressor gene cause the hereditary diffuse gastric cancer syndrome. Total gastrectomy is recommended for prevention, although it is associated with adverse outcomes and chronic health risks. Gastric cancer surveillance is an alternative to surgery; however, upper gastrointestinal endoscopy is limited by poor sensitivity. Cancer surveillance requires accurate detection of early carcinoma and patient-specific disease penetrance estimates. Current clinical care should incorporate up-to-date information on variable disease penetrance, which does not seem to correlate with CDH1 genotype. Affected patients and families warrant a balanced presentation of options for cancer surveillance and prophylaxis.

Abstract
Emerging adults with a CDH1 pathogenetic or likely pathogenetic variant face a life altering decision to undergo prophylactic total gastrectomy (PTG) or to have frequent endoscopies for gastric cancer risk management. They are in a unique life stage with distinct characteristics, such as identity finding, career seeking, relationship exploring, establishing financial independence and planning for or pursuing pregnancy. Research has shown these emerging adults heavily weighed dietary and nutrition concerns after PTG on their decision making for both timing of surgery and whether they should or should not undergo the surgery. These concerns are valid because of the significant dietary and lifestyle modification that emerging adults need to commit to prevent common sequelae after PTG, which include early satiety, nausea, dumping syndrome, bile reflux, excessive weight loss, micronutrient deficiencies and metabolic bone disorders. Thus, working with a multidisciplinary team with expertise in CDH1 and hereditary diffuse gastric cancer, including a registered dietitian nutritionist, is essential for this population.

Abstract
The most effective option for gastric cancer risk management in individuals with a CDH1 germline pathogenic or likely pathogenic variant (PV) in Australia is prophylactic total gastrectomy (PTG). There is, however, increasing confidence in endoscopic surveillance as a risk management strategy thus affording individuals with a CDH1 PV with challenging decisions regarding their gastric cancer risk management. For young people, this decision-making comes at a complex development stage of emerging and young adulthood. This study aims to explore the factors that influence young people's decision-making about their gastric cancer risk management due to a CDH1 PV. Potential participants were identified and approached through the Parkville Familial Cancer Centre in Melbourne, Australia. Thematic analysis was used to interpret and analyze the data. Qualitative interviews were conducted with 13 people with a CDH1 PV aged 18 to 39 years, inclusive. The interviews found that participants' familial and shared experiences of cancer and risk management, perceived tolerance of uncertainty, and desire for control over their cancer risk were fundamental in their decision-making about their gastric cancer risk management. The participants' young adult life stage was also deemed particularly important in decisions about the timing of PTG. The findings of this study are vital to inform decisional counseling discussions with this unique population.

Abstract
Approximately 10% of patients with gastric cancer show familial aggregation and up to 3% are related to an inherited cancer syndrome. There are multiple germline pathogenic variants and cancer syndromes associated with an increased risk of gastric cancer. Appropriate assessment of familial and genetic risk may allow a personalized approach to gastric cancer prevention through screening and risk-reducing surgeries. The ability to better identify carriers with pathogenic genetic variants associated with gastric cancer before a diagnosis of cancer requires effective genetic risk assessment and testing, followed by optimal screening and surveillance recommendations to further reduce the morbidity and mortality.

Abstract
Background: Patients with hereditary diffuse gastric cancer (HDGC) and germline mutations in the E-cadherin gene, CDH1, have a very high cumulative lifetime risk of developing diffuse gastric cancer. In these patients, it is formally recommended to perform a prophylactic total gastrectomy (PTG). Materials and Methods: We analyzed the course of patients with HDGC who have undergone PTG in our institution. Pedigree analysis, preoperative screening results, operative course, postoperative data, and complete stomach pathologic examination were performed in all patients. Results: Seven patients with confirmed CDH1 mutation underwent PTG, five were women, and average age was 27 years (range 17-42). Signet ring cell carcinoma was found in 1 patient in the preoperative surveillance endoscopic biopsies. Laparoscopic PTG was performed in all patients. There were two complications, an intestinal obstruction that required reintervention and an asymptomatic esophagojejunal anastomosis leak that resolved with conservative treatment. In all gastrectomy specimens, intramucosal signet ring cell carcinoma foci limited to the lamina propria were found (range 1-31), 83.5% were in the body-fundus region. The mean follow-up was 28.5 months (range 8-72). The mean weight loss was 9% (range 2-18). Postoperative symptoms associated with Dumping syndrome were the most frequent. All the patients reported of being very satisfied with the procedure and of having a better quality of life than expected before the procedure. Conclusion: Laparoscopic PTG is an excellent resource to prevent the development of advanced diffuse gastric cancer (DGC) in patients with HDGC with CDH1 mutation. The procedure was well tolerated with a high satisfaction rate and very good functional results. It should be considered in these patients due to the high risk of developing advanced DGC and the lack of effective and reliable surveillance studies.

Abstract
The use of the robotic platform for gastrointestinal surgery was introduced nearly 20 years ago. However, significant growth and advancement has occurred primarily in the last decade. This is due to several advantages over traditional laparoscopic surgery allowing for more complex dissections and reconstructions. Several randomized controlled trials and retrospective reviews have demonstrated equivalent oncologic outcomes compared to open surgery with improved short-term outcomes. Unfortunately, there are currently no universally accepted or implemented training programs for robotic surgery and robotic surgery experience varies greatly. Additionally, several limitations to the robotic platform exist resulting in a distinct learning curve associated with various procedures. Therefore, implementation of robotic surgery requires a multidisciplinary team approach with commitment and investment from clinical faculty, operating room staff and hospital administrators. Additionally, there is a need for wider distribution of educational modules to train more surgeons and reduce the associated learning curve. This article will focus on the implementation of the robotic platform for surgery of the pancreas, stomach, liver, colon and rectum with an emphasis on the associated learning curve, educational platforms to develop proficiency and perioperative outcomes.

[PMID: 34073553 PMCID: PMC8199234 DOI: 10.3390/cancers13112622] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 05/13/2021] [Accepted: 05/22/2021] [Indexed: 12/24/2022] Open
Abstract
Simple Summary Some patients carry a mutated copy of the CDH1 gene that can lead to a very rare form of hereditary gastric cancer called signet-ring cell adenocarcinoma (SRCC). SRCCs rarely form visible tumors prior to spreading. Hence, patients are recommended to have prophylactic gastrectomies at a young age. Many patients wish to avoid surgery and thus have regular checks with upper endoscopy with biopsies to rule out cancer. Further, these patients may also be at risk of other cancers beyond the already known breast cancer risks, but this is not known. In this study, we show that despite systematic biopsy protocols, many early cancers might be missed on endoscopy. Therefore, patients should not rely on endoscopy to delay surgery. These patients may also be at increased risk of colorectal SRCC, which has very poor survival outcomes. To confirm this, we need a central database that captures outcomes for this patient population. Abstract Hereditary diffuse gastric cancer (HDGC) is a rare signet-ring cell adenocarcinoma (SRCC) linked to CDH1 (E-cadherin) inactivating germline mutations, and increasingly other gene mutations. Female CDH1 mutation carriers have additional risk of lobular breast cancer. Risk management includes prophylactic total gastrectomy (PTG). The utility of endoscopic surveillance is unclear, as early disease lacks macroscopic lesions. The current systematic biopsy protocols have unknown efficacy, and other secondary cancer risks are postulated. We conducted a retrospective study of consecutive asymptomatic HDGC patients undergoing PTG, detailing endoscopic, pathologic, and outcome results. A systematic review compared endoscopic biopsy foci detection via random sampling versus Cambridge Protocol against PTG findings. A population-level secondary-cancer-risk postulation among sporadic gastric SRCC patients was completed using the Surveillance, Epidemiology, and End Results database. Of 97 patients, 67 underwent PTG, with 25% having foci detection on random endoscopic biopsy despite 75% having foci on final pathology. There was no improvement in the endoscopic detection rate by Cambridge Protocol. The postulated hazard ratio among sporadic gastric SRCC patients for a secondary colorectal SRCC was three-fold higher, relative to conventional adenocarcinoma patients. Overall, HDGC patients should not rely on endoscopic surveillance to delay PTG, and may have secondary SRCC risks. A definitive determination of actual risk requires collaborative patient outcome data banking.

Abstract
Hereditary diffuse gastric cancer (HDGC) is a cancer syndrome caused by germline variants in CDH1, the gene encoding the cell-cell adhesion molecule E-cadherin. Loss of E-cadherin in cancer is associated with cellular dedifferentiation and poor prognosis, but the mechanisms through which CDH1 loss initiates HDGC are not known. Using single-cell RNA sequencing, we explored the transcriptional landscape of a murine organoid model of HDGC to characterize the impact of CDH1 loss in early tumourigenesis. Progenitor populations of stratified squamous and simple columnar epithelium, characteristic of the mouse stomach, showed lineage-specific transcriptional programs. Cdh1 inactivation resulted in shifts along the squamous differentiation trajectory associated with aberrant expression of genes central to gastrointestinal epithelial differentiation. Cytokeratin 7 (CK7), encoded by the differentiation-dependent gene Krt7, was a specific marker for early neoplastic lesions in CDH1 carriers. Our findings suggest that deregulation of developmental transcriptional programs may precede malignancy in HDGC. © 2021 The Pathological Society of Great Britain and Ireland.

Abstract
Importance Inherited variants in the tumor suppressor gene CDH1 are associated with an increased risk of gastric and breast cancers. This review aims to address the most current topics in management of the hereditary diffuse gastric cancer syndrome attributed to CDH1. Observations Consensus management guidelines have broadened genetic testing criteria for CDH1. Prophylactic total gastrectomy is recommended for any pathogenic or likely pathogenic CDH1 variant carrier starting at the age of 20 years. Annual surveillance endoscopy is recommended to those who defer prophylactic total gastrectomy. Women with a CDH1 variant should initiate magnetic resonance imaging breast surveillance starting at age 30 years. Further research is needed to understand the pathogenesis of early-stage gastric cancers (T1a), which are pathognomonic of hereditary diffuse gastric cancer syndrome, that lead to advanced gastric cancer to develop both treatment and prevention strategies for this patient population. Conclusions and Relevance The heritable CDH1 gene mutation is of importance to today's surgeons because it is associated with a substantial increased risk of developing both gastric and breast cancers. Management of this cancer syndrome currently uses prophylactic surgery and enhanced cancer surveillance strategies.

Abstract
Importance CDH1 variants are increasingly identified on commercially available multigene panel tests, calling for data to inform counseling of individuals without a family history of gastric cancer. Objectives To assess association between CDH1 variant pathogenicity or family history of gastric or lobular breast cancer and identification of signet ring cell cancer and to describe outcomes of risk-reducing minimally invasive and open total gastrectomy. Design, Setting, and Participants This cohort study was performed from January 1, 2006, to January 1, 2020, in 181 patients with CDH1 germline variants from a single institution. Interventions Genetic counseling, esophagogastroduodenoscopy, and possible total gastrectomy. Main Outcomes and Measures CDH1 variant classification, family cancer history, findings of signet ring cell carcinoma at esophagogastroduodenoscopy and surgery, postoperative events and weight changes, and follow-up. Results Of 181 individuals with CDH1 germline variants (mean [SD] age at time of testing, 44 [15] years; 126 [70%] female), 165 harbored a pathogenic or likely pathogenic variant. Of these patients, 101 underwent open (n = 58) or minimally invasive (n = 43) total gastrectomy. Anastomotic leaks that required drainage were infrequent (n = 3), and median long-term weight loss was 20% (interquartile range [IQR], 10%-23%). In those undergoing minimally invasive operations, more lymph nodes were retrieved (median, 28 [IQR, 20-34] vs 15 [IQR, 9-19]; P < .001) and the hospital stay was 1 day shorter (median, 6 [IQR, 5-7] vs 7 [IQR, 6-7] days; P = .04). Signet ring cell cancer was identified in the surgical specimens of 85 of 95 patients (89%) with a family history of gastric cancer and 4 of 6 patients (67%) who lacked a family history. Among the latter 6 patients, 4 had a personal or family history of lobular breast cancer, including 2 with signet ring cell cancer. Of the 16 patients with pathogenic or likely pathogenic CDH1 variants who presented with locally advanced or metastatic gastric cancer, 3 (19%) had no family history of gastric cancer or personal or family history of lobular breast cancer. Conclusions and Relevance Total gastrectomy may be warranted for patients with pathogenic or likely pathogenic CDH1 variants and a family history of gastric or lobular breast cancer and may be appropriate for those without a family history. A minimally invasive approach is feasible and may be preferred for selected patients.

Abstract
Hereditary diffuse gastric cancer (HDGC) is a cancer syndrome associated with a significant lifetime risk of diffuse gastric cancer (DGC), a malignancy characterized by late clinical presentation and poor prognosis, as well as lobular breast cancer. HDGC is linked to germline pathogenic variants in the E-cadherin gene (CDH1) that are inherited in an autosomal dominant pattern; however, in many families with DGC clustering, no genetic cause has been identified. This review discusses key elements that allow risk assessment of potential inherited DGC susceptibility. We provide a practical overview of the recommendations for surveillance and treatment of individuals at risk and patients with early disease. The review also outlines future research avenues to improve our understanding of the genetic background and natural history of the disease, the endoscopic detection of early lesions, and the outcome of prophylactic surgery in young individuals.

Abstract
Background Germline mutations in E‐cadherin (CDH1) gene are associated with autosomal‐dominantly inherited cancer syndrome characterized by diffuse gastric cancer, lobular breast cancer, and in some families, cleft lip/palate. However, there may be generations in which these neoplasms do not occur at all in a family and later on, one or another carcinoma arises, which makes it difficult for physicians to think about hereditary origin. Methods We report the first Mexican family with CDH1 mutation (variant c.377del). Results An asymptomatic young woman underwent a search for mutations in susceptibility genes for breast cancer due to the history of this neoplasm in her mother and maternal aunt. A CDH1 mutation was detected. After an endoscopy, a diffuse gastric carcinoma was found. Later on, three generations of this family were studied. The findings are presented. Conclusion Medical communities should be aware of the contribution of this gene in the development of hereditary diffuse gastric carcinoma (HDGC) and breast cancer.

Abstract
Hereditary diffuse gastric cancer (HDGC) is an autosomal dominant cancer syndrome that is characterised by a high prevalence of diffuse gastric cancer and lobular breast cancer. It is largely caused by inactivating germline mutations in the tumour suppressor gene CDH1, although pathogenic variants in CTNNA1 occur in a minority of families with HDGC. In this Policy Review, we present updated clinical practice guidelines for HDGC from the International Gastric Cancer Linkage Consortium (IGCLC), which recognise the emerging evidence of variability in gastric cancer risk between families with HDGC, the growing capability of endoscopic and histological surveillance in HDGC, and increased experience of managing long-term sequelae of total gastrectomy in young patients. To redress the balance between the accessibility, cost, and acceptance of genetic testing and the increased identification of pathogenic variant carriers, the HDGC genetic testing criteria have been relaxed, mainly through less restrictive age limits. Prophylactic total gastrectomy remains the recommended option for gastric cancer risk management in pathogenic CDH1 variant carriers. However, there is increasing confidence from the IGCLC that endoscopic surveillance in expert centres can be safely offered to patients who wish to postpone surgery, or to those whose risk of developing gastric cancer is not well defined.

Abstract
BACKGROUND While multiple Asian and a few Western retrospective series have demonstrated the feasibility and safety of robotic-assisted gastrectomy for gastric cancer, its reliability for thorough resection, especially for locoregional disease, has not yet been firmly established, and reported learning curves vary widely. To support wider implementation of robotic gastrectomy, we evaluated the learning curve for this approach, assessed its oncologic feasibility, and created a selection model predicting the likelihood of conversion to open surgery in a US patient population. PATIENTS AND METHODS We retrospectively reviewed data on all consecutive patients who underwent robotic gastrectomy at a high-volume institution between May 2012 and March 2019. RESULTS Of the 220 patients with gastric cancer selected to undergo curative-intent robotic gastrectomy, surgery was completed using robotics in 159 (72.3%). The median number of removed lymph nodes was 28, and ≥ 15 lymph nodes were removed in 94% of procedures. Surgical time decreased steadily over the first 60-80 cases. Complications were generally minor: 7% of patients experienced complications of grade 3 or higher, with an anastomotic leak rate of 2% and mortality rate 0.9%. Factors predicting conversion to open surgery included neoadjuvant chemotherapy, BMI ≥ 31 kg/m2, and tumor size ≥ 6 cm. CONCLUSIONS These findings support the safety and oncologic feasibility of robotic gastrectomy for selected patients with gastric cancer. Proficiency can be achieved by 20 cases and mastery by 60-80 cases. Ideal candidates for this approach are patients with few comorbidities, BMI < 31 kg/m2, and tumors < 6 cm.

[PMID: 31220641 DOI: 10.1016/j.cgh.2019.06.009] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 05/07/2019] [Accepted: 06/07/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Carriers of pathogenic variants in CDH1 have a high risk of hereditary diffuse gastric cancer (HDGC). Guidelines recommend prophylactic total gastrectomy (PTG) at age 20-30 years, although there is controversy over the optimal age. We developed a simulation model to analyze the effects of PTG at different ages on quality-adjusted life-years (QALYs), cancer mortality, and life expectancy. METHODS We used a Markov model of HDGC progression associated with pathogenic variants in CDH1 to simulate outcomes of hypothetical cohorts with different ages at time of PTG (ages 20-79 years). Model inputs including health state transition probabilities, mortality and complication rates, quality of life utility values, and endoscopic surveillance sensitivity were derived from publications. The primary outcome, used to determine the optimal strategy, was age at which PTG yielded the highest QALYs. Secondary outcomes were cancer mortality and unadjusted life-years. RESULTS Our model found that for men, the optimal age for PTG is 39 years, resulting in 32.01 incremental QALYs, 58.81 life-years (biologic age, 72.81 years), and lifetime cancer mortality of 8.5%. Incorporating endoscopic surveillance prior to PTG decreased cancer mortality to 6.7%, but had lower QALYs (31.59). PTG at age 30 reduced cancer mortality to 3.2%, with 31.45 incremental QALYs. For women, the optimal age for PTG was calculated to be 30 years, with 33.09 incremental QALYs, 66.17 life-years (biologic age, 80.17 years), and lifetime cancer mortality of 1.6%. Addition of endoscopic surveillance did not decrease the risk of HDGC mortality in women. CONCLUSIONS Using a Markov model of HDGC progression associated with pathogenic variants in CDH1 to simulate outcomes, we found the optimal ages for PTG to be 39 years for men and 30 years for women, when QALYs are the primary endpoint. These ages for PTG are older than those of current recommendations.

Abstract
Multigene panel testing (MGPT) has become a critical component of cancer risk assessment in clinical practice. As technology and access improve and costs decrease, more individuals than ever are undergoing MGPT for genetic evaluation. One gene that deserves special consideration when included on MGPT is CDH1, which codes for the cell-cell adhesion protein E-cadherin. Pathogenic and likely pathogenic germline variants in CDH1 have been associated with hereditary diffuse gastric cancer syndrome, and in highly penetrant families, testing for these variants is critical for proper risk management. However, recent data demonstrated that gastric cancer penetrance in unselected CDH1 carriers may be lower than expected. Further complicating matters are the lack of effective screening strategies for gastric cancer and recommendation for risk-reducing total gastrectomy in CDH1 carriers. Therefore, the discovery of an unexpected pathogenic or likely pathogenic CDH1 variant on multigene panel testing, when testing for CDH1 would not normally be considered based on personal or family history alone, creates dilemmas for both patients and providers. In this commentary, we highlight the potential for unexpected CDH1 variants on MGPT, outline the uncertainties associated with these variants, and emphasize the importance of pretest counseling regarding the potential for an unexpected CDH1 variant. Although CDH1 testing is often important for clinical decision-making, individuals and providers need to be aware of the potential for an unexpected CDH1 variant when CDH1 is included on MGPT for cancer risk assessment.

Abstract
INTRODUCTION hereditary diffuse gastric cancer (HDGC) is a recently reported hereditary cancer syndrome. Patients with suspected HDGC must be under surveillance via endoscopy and multiple biopsies. As an alternative, some studies suggest prophylactic gastrectomy (PG) for disease carriers. The goal of this article was to report our experience with a CDH1 mutation positive family who underwent PG. PATIENTS AND METHODS the index case was a 34-year-old female diagnosed with diffuse gastric adenocarcinoma and massive carcinomatosis. There was a family history of gastric adenocarcinoma in seven family members. A genetic study identified the c.1577G>A mutation, in exon 11 of the CDH1 gene via sequencing analysis. RESULTS this mutation was also present in other six family members, who subsequently underwent prophylactic gastrectomy. The pathology study of resected gastric segments revealed multiple microscopic foci of adenocarcinoma in five of these individuals. These foci were not detected in the multiple endoscopies performed before surgery. CONCLUSIONS we recommend prophylactic gastrectomy for CDH1 mutation carriers even in the absence of lesions during endoscopic screening.

Abstract
Germline CDH1 mutation carriers are at risk for early-onset diffuse gastric cancer (DGC) and female carriers have an additional risk of lobular breast cancer. The reported literature GC risk of 70% has led to the recommendation for germline mutation carriers to undergo prophylactic total gastrectomy (PTG). The objective of this research was to examine post-surgical clinical outcomes and to identify which of the domains/symptoms from the European Organisation for Research and Treatment of Cancer QOL Questionnaire (EORTC QLQ-C30) were determinants of overall quality of life (QOL) in individuals undergoing PTG. Participants were recruited through multiple sources. Postsurgical clinical outcomes were obtained from hospital records. Participants completed validated questionnaires measuring generic and condition specific QOL (PROMIS, EORTC and SF 36v.II) at a single point in time. The mean QOL in this cohort was 70.6 (SD = 25.6), which is better than reference values from the general populations in USA and Canada Role and social function plus the symptoms anxiety, pain, taste, dyspnea and diarrhea were significant predictor variables for QOL (p < 0.05). Although this study reveals good overall QOL for individuals after PTG, attention should be given to managing symptoms as part of long term care to further enhance QOL. The function/symptom scores were associated with worse overall health and global health status and thus may mark a real need for more attentive post-surgical care.

Abstract
Germline pathogenic variants in the CDH1 gene are a well-established cause of hereditary diffuse gastric cancer (HDGC) syndrome. The aim of this study was to characterize CDH1 mutations associated with HDGC from Chile, a country with one of the highest incidence and mortality rates in the world for gastric cancer (GC). Here, we prospectively include probands with family history/early onset of diffuse-type of GC. The whole coding sequence of the CDH1 gene was sequenced from genomic DNA in all patients, and a multidisciplinary team managed each family member with a pathogenic sequence variant. Thirty-six cases were included (median age 44 years/male 50%). Twenty-seven (75%) patients had diffuse-type GC at ≤50 years of age and 19 (53%) had first or second-degree family members with a history of HDGC. Two cases (5.5%) carried a non-synonymous germline sequence variant in the CDH1 gene: (a) The c.88C>A missense variant was found in a family with three diffuse-type GC cases; and (b) c.1531C>T a nonsense pathogenic variant was identified in a 22-year-old proband with no previous family history of HDGC. Of note, six family members carry the same nonsense pathogenic variant. Prophylactic gastrectomy in the proband's sister revealed stage I signet-ring cell carcinoma. The finding of 1531C>T pathogenic variant in the CDH1 in proband with no previous family history of HDGC warrants further study to uncover familial clustering of disease in CDH1 negative patients. This finding may be particularly relevant in high incidence countries, such as the case in this report.

Abstract
The cell-cell adhesion protein E-cadherin (CDH1) is a tumor suppressor that is required to maintain cell adhesion, cell polarity and cell survival signalling. Somatic mutations in CDH1 are common in diffuse gastric cancer (DGC) and lobular breast cancer (LBC). In addition, germline mutations in CDH1 predispose to the autosomal dominant cancer syndrome Hereditary Diffuse Gastric Cancer (HDGC). One approach to target cells with mutations in specific tumor suppressor genes is synthetic lethality. To identify novel synthetic lethal compounds for the treatment of cancers associated with E-cadherin loss, we have undertaken a high-throughput screening campaign of ~114,000 lead-like compounds on an isogenic pair of human mammary epithelial cell lines - with and without CDH1 expression. This unbiased approach identified 12 novel compounds that preferentially harmed E-cadherin-deficient cells. Validation of these compounds using both real-time and end-point viability assays identified two novel compounds with significant synthetic lethal activity, thereby demonstrating that E-cadherin loss creates druggable vulnerabilities within tumor cells. In summary, we have identified novel synthetic lethal compounds that may provide a new strategy for the prevention and treatment of both sporadic and hereditary LBC and DGC.

Abstract
Gastric cancer is the third leading cause of cancer mortality worldwide. Survival is linked to stage at diagnosis and tolerance to surgery and adjuvant therapy. The emergence of sophisticated methods to identify patients at high risk for the development of gastric cancer has given us an opportunity to eliminate a lethal disease in an identifiable patient population. Guidelines and recommendations have been established and prophylactic total gastrectomy is considered the most effective treatment. However, this requires substantial physical and emotional investment. It is imperative that patients and families are supported by genetic counseling, ongoing surveillance, and survivorship studies.

Abstract
BACKGROUND Patients with hereditary diffuse gastric cancer and a CDH1 mutation have a 60-80 per cent lifetime risk of developing diffuse gastric cancer. Total prophylactic gastrectomy eliminates this risk, but is associated with considerable morbidity. The effectiveness (removal of all gastric mucosa) and outcomes of this procedure were evaluated retrospectively. METHODS All consecutive individuals undergoing a prophylactic gastrectomy for a CDH1 mutation or gastric signet ring cell foci at the authors' institute between 2005 and 2017 were included. RESULTS In 25 of 26 patients, intraoperative frozen-section examination (proximal resection margin) was used to verify complete removal of gastric mucosa. All definitive resection margins were free of gastric mucosa, but only after the proximal margin had been reresected in nine patients. In the first year after surgery, five of the 26 patients underwent a relaparotomy for adhesiolysis (2 patients) or jejunostomy-related complications (3 patients). Six patients were readmitted to the hospital within 1 year for nutritional and/or psychosocial support (4 patients) or surgical reintervention (2 patients). Mean weight loss after 1 year was 15 (95 per cent c.i. 12 to 18) per cent. For the 25 patients with a follow-up at 1 year or more, functional complaints were reported more frequently at 1 year than at 3 months after the operation: bile reflux (15 versus 11 patients respectively) and dumping (11 versus 7 patients). The majority of patients who worked or studied before surgery (15 of 19) had returned fully to these activities within 1 year. CONCLUSION The considerable morbidity and functional consequences of gastrectomy should be considered when counselling individuals with an inherited predisposition to diffuse gastric cancer. Intraoperative frozen-section examination is recommended to remove all risk-bearing gastric mucosa.

Abstract
Regional variation in treatment paradigms for gastric adenocarcinoma has attracted a great deal of interest. Between Asia and the West, major differences have been identified in tumor biology, implementation of screening programs, extent of surgical lymphadenectomy, and routine use of neoadjuvant versus adjuvant treatment strategies. Minimally invasive techniques, including both laparoscopic and robotic platforms, have been studied in both regions, with attention to safety, feasibility, and long-term oncologic outcomes. The purpose of this review is to discuss advances in the understanding of the etiology and underlying biology of gastric cancer, as well as the current state of management, focusing on the differences between Asia and the West.

Abstract
Gastric cancer, as a malignant epithelial tumor, is a major health threat leading to poor overall survival and death. It is usually diagnosed at an advanced stage due to asymptomatic or only nonspecific early symptoms. The present study demonstrated that gankyrin contributes to the early malignant transformation of gastric cancer and can be selected to predict the risk of gastric cancer in those patients harboring the precancerous lesions (dysplasia and intestinal metaplasia). In addition, a new insight into gastric cancer was provided, which stated that gankyrin alleviates oxidative stress via mTORC1 pathway activation. It can potentiate the mTORC1 by PGK1-AKT signaling that promotes the tumor process, and this phenomenon is not completely consistent with the previous report describing colorectal cancer.

Abstract
With a current molecular revolution, hereditary gastric cancer represents a small group of patients that require a special multidisciplinary treatment. Surgeons being a member of the multidisciplinary teams are an important part of the diagnosis, treatment and follow-up of these patients. The prophylactic nature of the gastrectomy with all different problems associated with this procedure need to be widely discussed with patients. We present a review of how to look for and how to manage a hereditary diffuse-type gastric cancer.

Abstract
Abstract
Background
Modern advances in genetic sequencing techniques have allowed for increased availability of genetic testing for hereditary cancer syndromes. Consequently, more people are being identified as mutation carriers and becoming aware of their increased risk of malignancy. Testing is commonplace for many inheritable cancer syndromes, and with that comes the knowledge of being a gene carrier for some patients. With increased risk of malignancy, many guidelines recommend that gene carriers partake in risk reduction strategies, including risk-reducing surgery for some syndromes. This review explores the quality-of-life consequences of genetic testing and risk-reducing surgery.
Methods
A narrative review of PubMed/MEDLINE was performed, focusing on the health-related quality-of-life implications of surgery for hereditary breast and ovarian cancer, familial adenomatous polyposis and hereditary diffuse gastric cancer.
Results
Risk-reducing surgery almost uniformly decreases cancer anxiety and affects patients' quality of life.
Conclusion
Although the overwhelming quality-of-life implications of surgery are neutral to positive, risk-reducing surgery is irreversible and can be associated with short- and long-term side-effects.
