Psychosocial issues in genetic testing for familial adenomatous polyposis: a review of the literature

[Surgical strategies for hereditary colorectal cancer]

Hereditary colorectal cancer (hCRC) represents a major diagnostic and therapeutic challenge. In addition to the usual diagnostic methods, the family history, histological confirmation and mutation analysis play an important role in identifying the type of hereditary CRC. The diagnosis and classification of hCRC are carried out based on the anamnesis, clinical presentation and histology and the further treatment is determined depending on the underlying type of hCRC. For familial adenomatous polyposis (FAP) coloproctomucosectomy after the end of puberty is always recommended, whereas the treatment recommendations for other forms, such as attenuated FAP (aFAP), MUTYH-associated polyposis (MAP) and hereditary nonpolyposis colon cancer (HNPCC, Lynch syndrome), range from close surveillance and endoscopic control, through segmental resection up to colectomy. Irrespective of the type of hCRC, the treatment regimens necessitate an individualized approach and require close interdisciplinary cooperation. When colorectal resection is performed, minimally invasive procedures should principally be prioritized and some studies could demonstrate a potential benefit of robotic surgery compared to laparoscopy.

Distress facing increased genetic risk of cancer: The role of social support and emotional suppression

OBJECTIVES

Healthy individuals from hereditary cancer families undergoing genetic testing for cancer susceptibility (GTC) report more distress when they perceive their social support as low and suppress their emotions. This study aimed to explore how suppressing emotions and perceiving others as unsupportive are related with cancer-risk distress.

METHODS

We performed a regression-based mediation analysis to assess if expressive suppression mediates or is mediated by perceived social support in the relation with cancer-risk distress. Participants were 125 healthy adults aged over 18 (M = 36.07, SD = 12.86), mostly female (72,4%), who undergone GTC to assess the presence of hereditary breast and ovarian cancer or Lynch syndromes.

RESULTS

Controlling for age and gender, we found a moderate size indirect effect of social support on cancer-risk distress through expressive suppression (β = -0.095) and a direct effect of expressive suppression on cancer-risk distress.

CONCLUSIONS

When healthy individuals from hereditary cancer families perceive their social network as less responsive, they tend to not express their emotions, which relates to increased distress facing GTC.

PRACTICE IMPLICATIONS

Practitioners may assess cancer-risk related distress before the GTC and offer distressed individuals interventions focused on changing emotion regulation strategies in a safe group context.

Mental Health Symptoms in Patients With Familial Adenomatous Polyposis: An Observational Study

BACKGROUND

Almost all patients with familial adenomatous polyposis undergo abdominal surgery with a risk of disease and surgery-related complications. This, the familial nature of the syndrome, and its wide-ranging manifestations make patients prone to mental health symptoms. If this is true, patients need appropriate evaluation and treatment.

OBJECTIVE

The purpose of this study was to record the experience of mental health symptoms in a group of unselected patients with FAP.

DESIGN

We conducted an observational study using an anonymized mental health symptom survey for patients affected with familial adenomatous polyposis.

SETTINGS

The study was conducted using the Hereditary Colorectal Cancer Registry in a tertiary referral center.

PATIENTS

Patients affected with familial adenomatous polyposis were included.

MAIN OUTCOME MEASURES

Results of the mental health survey were measured.

RESULTS

Seventy nine of 100 patients completed the survey; 57 endorsed ≥1 psychosocial symptom (72.2%). with a mean of 4 per patient. Nine patients (11.4%) met all 4 of the American Psychiatric Association diagnostic criteria for posttraumatic stress disorder, and 8 (10.1%) endorsed partial posttraumatic stress disorder criteria (3/4 symptoms). Patients who met all of the criteria for posttraumatic stress disorder had an average of 9.3 psychosocial symptoms each compared with 8.3 for those who met 3 of 4 and 2.2 for those who met <3. Six patients endorsed suicidal thoughts, all of whom met 3 or 4 of the criteria for posttraumatic stress disorder.

LIMITATIONS

The study was limited by its referral bias toward severe cases and relatively small number of patients. Because of the limitations of an anonymous self-administered screening, no mental health diagnoses have been given.

CONCLUSIONS

Patients with familial adenomatous polyposis are at risk for mental health symptoms, which can be multiple and severe. Some patients need professional counseling. A correlation between familial adenomatous polyposis patients with posttraumatic stress disorder and suicidal ideation is important. See Video Abstract at http://links.lww.com/DCR/A995.

RESULTADOS

Setenta y nueve de 100 pacientes completaron la encuesta; 57 afirmaron uno o más síntomas psicosociales (72,2%) con un promedio de 4 por paciente. 9 (11,4%) pacientes cumplieron con los 4 criterios de diagnóstico de la Asociación Estadounidense de Psiquiatría para el trastorno por estrés postraumático, y 8 (10,1%) llenaron los criterios del trastorno de estrés postraumático parcial (3/4 síntomas). Los pacientes que cumplieron con todos los criterios para el trastorno por estrés postraumático tuvieron un promedio de 9.3 síntomas psicosociales cada uno, en comparación con 8.3 para los que cumplieron con 3/4 y 2.2 para los que cumplieron con <3. 6 pacientes afirmaron pensamientos de suicidio, todos los cuales cumplieron con 3 o 4 de los criterios para el trastorno por estrés postraumático.

LIMITACIONES

Sesgo de referencia hacia casos graves, y un número relativamente pequeño de pacientes. Debido a las limitaciones de un examen anónimo auto administrado, no se confirmaron diagnósticos de psicopatología.

CONCLUSIONES

Los pacientes con póliposis adenomatoso familiar tienen riesgo de síntomas de salud mental alterada que pueden ser múltiples y graves. Algunos pacientes necesitan asesoramiento profesional. La correlación entre los pacientes con póliposis adenomatoso familiar con trastorno por estrés postraumático y ideación suicida es importante.

Study protocol of the CORRECT multicenter trial: the efficacy of blended cognitive behavioral therapy for reducing psychological distress in colorectal cancer survivors

BACKGROUND

Approximately one third of the colorectal cancer survivors (CRCS) experience high levels of psychological distress. Common concerns experienced by CRCS include distress related to physical problems, anxiety, fear of cancer recurrence (FCR) and depressive symptoms. However, psychological interventions for distressed CRCS are scarce. Therefore, a blended therapy was developed, combining face-to-face cognitive behavioral therapy (CBT) with online self-management activities and telephone consultations. The aim of the study is to evaluate the efficacy and cost-effectiveness of this blended therapy in reducing psychological distress in CRCS.

METHODS/DESIGN

The CORRECT study is a two-arm multicenter randomized controlled trial (RCT). A sample of 160 highly distressed CRCS (a score on the Distress Thermometer of 5 or higher) will be recruited from several hospitals in the Netherlands. CRCS will be randomized to either the intervention condition (blended CBT) or the control condition (care as usual). The blended therapy covers approximately 14 weeks and combines five face-to-face sessions and three telephone consultations with a psychologist, with access to an interactive self-management website. It includes three modules which are individually-tailored to patient concerns and aimed at decreasing: 1) distress caused by physical consequences of CRC, 2) anxiety and FCR, 3) depressive symptoms. Patients can choose between the optional modules. The primary outcome is general distress (Brief Symptom Inventory-18). Secondary outcomes are quality of life and general psychological wellbeing. Assessments will take place at baseline prior to randomization, after 4 and 7 months.

DISCUSSION

Blended CBT is an innovative and promising approach for providing tailored supportive care to reduce high distress in CRCS. If the intervention proves to be effective, an evidence-based intervention will become available for implementation in clinical practice.

TRIAL REGISTRATION

This trial is registered in the Netherlands Trial Register ( NTR6025 ) on August 3, 2016.

SCA2 predictive testing in Cuba: challenging concepts and protocol evolution

Spinocerebellar ataxia type 2 (SCA2) is a neurodegenerative disease caused by a CAG repeat expansion in the ATXN2 gene. Cuba has the highest prevalence (6.57 cases/10(5) inhabitants) of SCA2 in the world. The existence of 753 affected individuals and 7173 relatives at risk prompted the development in 2001 of the first predictive testing program in the country. The medical records of over 1193 individuals, who requested the test within a 13-year period, were analyzed retrospectively. The presymptomatic and the prenatal tests had uptake rates of 43.4 and 23.9 %, respectively. Several ethical challenges resulted from this program. These include the following: (1) withdrawal due to the initial protocol's length; (2) the request to participate by 16 at-risk adolescents; (3) the decision made by ten out of 33 couples with a test-positive fetus to carry the pregnancy to term, leading to de facto predictive testing of minors; (4) the elevated frequency of the ATXN2 gene large normal alleles (≥23 to 31 repeats) in the reference population. These issues have led to major changes in the guidelines of the predictive testing protocol: (1) the protocol length was shortened; (2) the inclusion criteria were expanded to reach at-risk adolescents with an interest in prenatal diagnosis; (3) interdisciplinary follow-up was offered to families in which test-positive fetuses were not aborted; (4) prenatal testing was made available to carriers of large normal alleles with ≥27 CAG repeats. The profiles of the participants were similar to those reported for other predictive testing programs for conditions like Huntington disease and familial adenomatous polyposis. The genetic counseling practices at the community level, the ample health education provided to the at-risk population, together with multidisciplinary and specialized attention to the affected families, are lessons from the Cuban experience that can be relevant for other international teams conducting predictive testing for other late-onset neurodegenerative disorders.

Effect of routine assessment of specific psychosocial problems on personalized communication, counselors’ awareness, and distress levels in cancer genetic counseling practice: a randomized controlled trial

PURPOSE

This study evaluated the efficacy of a cancer genetics–specific questionnaire in facilitating communication about, awareness of, and management of psychosocial problems, as well as in lowering distress levels.

METHODS

Individuals referred to genetic counseling for cancer at two family cancer clinics in The Netherlands were randomly assigned to an intervention or a control group. All participants completed the psychosocial questionnaire before counseling. In the intervention group, the counselors received the results of this questionnaire before the counseling session. All sessions were audiotaped for content analysis. Primary outcomes were the frequency with which psychosocial problems were discussed, the genetic counselors’ awareness of these problems, and their management. Secondary outcomes included cancer worries and psychological distress, duration and dynamics of the counseling, and satisfaction.

RESULTS

The frequency with which psychosocial problems were discussed with 246 participating counselees was significantly higher in the intervention group (n = 127) than in the control group (n =119; P = .004), as was the counselors’ awareness of psychosocial problems regarding hereditary predisposition (P < .001), living with cancer (P = .01), and general emotions (P < .001). Counselors initiated more discussion of psychosocial problems in the intervention group (P < .001), without affecting the length of the counseling session. No significant differences were found on management (P = .19). The intervention group reported significantly lower levels of cancer worries (p = .005) and distress (p = .02) after counseling.

CONCLUSION

The routine assessment of psychosocial problems by questionnaire facilitates genetic counselors’ recognition and discussion of their clients’ psychosocial problems and reduces clients’ distress levels.

Social and behavioral research in genomic sequencing: approaches from the Clinical Sequencing Exploratory Research Consortium Outcomes and Measures Working Group

The routine use of genomic sequencing in clinical medicine has the potential to dramatically alter patient care and medical outcomes. To fully understand the psychosocial and behavioral impact of sequencing integration into clinical practice, it is imperative that we identify the factors that influence sequencing-related decision making and patient outcomes. In an effort to develop a collaborative and conceptually grounded approach to studying sequencing adoption, members of the National Human Genome Research Institute's Clinical Sequencing Exploratory Research Consortium formed the Outcomes and Measures Working Group. Here we highlight the priority areas of investigation and psychosocial and behavioral outcomes identified by the Working Group. We also review some of the anticipated challenges to measurement in social and behavioral research related to genomic sequencing; opportunities for instrument development; and the importance of qualitative, quantitative, and mixed-method approaches. This work represents the early, shared efforts of multiple research teams as we strive to understand individuals' experiences with genomic sequencing. The resulting body of knowledge will guide recommendations for the optimal use of sequencing in clinical practice.

The efficacy of a standardized questionnaire in facilitating personalized communication about problems encountered in cancer genetic counseling: design of a randomized controlled trial

Background

Individuals with a personal or family history of cancer, can opt for genetic counseling and DNA-testing. Approximately 25% of these individuals experience clinically relevant levels of psychosocial distress, depression and/or anxiety after counseling. These problems are frequently left undetected by genetic counselors. The aim of this study is to evaluate the efficacy of a cancer genetics-specific screening questionnaire for psychosocial problems, the ‘Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire’ together with the Distress Thermometer, in: (1) facilitating personalized counselor-counselee communication; (2) increasing counselors’ awareness of their counselees’ psychosocial problems; and (3) facilitating the management of psychosocial problems during and after genetic counseling.

Methods

This multicenter, randomized controlled trial will include 264 individuals undergoing cancer genetic counseling in two family cancer clinics in the Netherlands. Participants will be randomized to either: (1) an intervention group that completes the PAHC questionnaire, the results of which are made available to the genetic counselor prior to the counseling session; or (2) a control group that completes the PAHC questionnaire, but without feedback being given to the genetic counselor. The genetic counseling sessions will be audiotaped for content analysis. Additionally, study participants will be asked to complete questionnaires at baseline, three weeks after the initial counseling session, and four months after a telephone follow-up counseling session. The genetic counselors will be asked to complete questionnaires at the start of and at completion of the study, as well as a checklist directly after each counseling session. The questionnaires/checklists of the study include items on communication during genetic counseling, counselor awareness of their clients’ psychosocial problems, the (perceived) need for professional psychosocial support, cancer worries, general distress, specific psychosocial problems, satisfaction with care received, and experience using the PAHC questionnaire.

Discussion

This study will provide empirical evidence regarding the efficacy of a relatively brief psychosocial screening questionnaire in terms of facilitating personalized communication, increasing counselors’ awareness, and optimizing management of psychosocial problems in the cancer genetic counseling setting.

Trial registration

This study is registered at the Netherlands Trial Register (NTR3205) and ClinicalTrials.gov (NCT01562431).

Specific psychosocial issues of individuals undergoing genetic counseling for cancer - a literature review

Approximately 25% of individuals undergoing genetic counseling for cancer experiences clinically relevant levels of distress, anxiety and/or depression. However, these general psychological outcomes that are used in many studies do not provide detailed information on the specific psychosocial problems experienced by counselees. The aim of this review was to investigate the specific psychosocial issues encountered by individuals undergoing genetic counseling for cancer, and to identify overarching themes across these issues. A literature search was performed, using four electronic databases (PubMed, PsychInfo, CINAHL and Embase). Papers published between January 2000 and January 2013 were selected using combinations, and related indexing terms of the keywords: 'genetic counseling', 'psychology' and 'cancer'. In total, 25 articles met our inclusion criteria. We identified the specific issues addressed by these papers, and used meta-ethnography to identify the following six overarching themes: coping with cancer risk, practical issues, family issues, children-related issues, living with cancer, and emotions. A large overlap in the specific issues and themes was found between these studies, suggesting that research on specific psychosocial problems within genetic counseling has reached a point of saturation. As a next step, efforts should be made to detect and monitor these problems of counselees at an early stage within the genetic counseling process.

Colorectal polyps in childhood

PURPOSE OF REVIEW

Colorectal polyps are a common cause of gastrointestinal bleeding in children. This review updates the information on colorectal polyps and summarizes the recent advances in genetics, diagnosis, and treatment of polyps in the large intestine.

RECENT FINDINGS

A review of recent literature regarding colorectal polyps demonstrates an estimated detected prevalence of 6.1% overall and 12.0% among those with lower gastrointestinal bleeding during pediatric colonoscopy. Non-Caucasian races (e.g., black and Hispanic) are at higher risk for colorectal polyps in childhood. Recent data show juvenile polyps may recur in approximately 45% of children with multiple polyps and 17% of children with solitary polyps. A clinical trial showed that celecoxib, a cyclooxygenase (COX)-2 inhibitor, significantly reduced the number of colorectal polyps in children with familial adenomatous polyposis (FAP). Ethical challenges related to genetic tests for FAP have been newly examined. The utility of novel endoscopic techniques (e.g., enteroscopy) in Peutz-Jeghers Syndrome to prevent intussusception have been newly described.

SUMMARY

Although colorectal polyps in children are generally benign and easily removed, careful clinical evaluation and ongoing research are needed to identify the small proportion of children at risk for cancer. The current paradigm of using the polyp number at presentation as a primary determinant of subsequent surveillance may be inadequate for many patients.

Screening and Health Behaviors among Persons Diagnosed with Familial Adenomatous Polyposis and Their Relatives

Familial Adenomatous Polyposis (FAP) is a rare autosomal dominantly inherited colorectal cancer syndrome. Individuals with FAP often undergo colectomy and are recommended to follow several surveillance protocols. Biological relatives of persons with FAP may also be at risk and thus should undergo genetic counseling. Screening adherence, genetic testing, and other health behaviors among individuals with FAP and their relatives are not well characterized. We conducted a cross-sectional self-report survey with individuals who have FAP (n = 35) and their biological relatives (n = 15). Respondents were recruited through a cancer center registry for inherited colon cancers. Most relatives had undergone colon cancer screening; 40% had undergone genetic testing. One fifth of respondents with FAP had not undergone an upper endoscopy, contrary to usual recommendations. Cigarette smoking rates were above average and were higher among FAP respondents. Use of vitamin supplements was fairly common, more so among those with FAP. Although most people had been screened, there are areas for improvement, notably for upper endoscopy among individuals with FAP and genetic testing among family members. Several other health-risk behaviors and health concerns other than FAP were identified. Further research into factors contributing to screening rates and other health behaviors in this high-risk population is warranted.

Quality of life and functional outcome for individuals who underwent very early colectomy for familial adenomatous polyposis

BACKGROUND

The major manifestation of familial adenomatous polyposis is colorectal adenomas, which, if untreated, lead to colorectal cancer. The impact of IPAA on quality of life in adolescents with familial adenomatous polyposis is favorable. There is a group of children who develop polyps at a younger age requiring earlier colectomy. Little is known about this very young subgroup in relation to bowel function or quality of life.

OBJECTIVE

The aim of this study was to investigate the outcome in patients with familial adenomatous polyposis who had colectomy at ≤14 years.

DESIGN

A cross-sectional quantitative survey was designed to assess outcome. Standardized validated instruments included bowel/psychosocial functioning and quality of life.

RESULTS

Among 1337 patients with familial adenomatous polyposis from 409 kindreds, 4% (n = 59) of patients underwent colectomy at ≤14 years of age. Response rate was 84% (n = 32). The mean age at colectomy was 12 years (SD 2), with a current mean age of 24 years (SD 8.5). Fifty-seven percent of patients reported continence. Of the 43% reporting daytime or nighttime incontinence, the majority are <18 years (86%). Younger participants (currently less than 18 years of age) report more restrictions. Mental health is significantly lower among participants with incontinence. They report higher depression and anxiety symptoms, higher levels of intrusion and avoidance, and inferior mental health. The percentage of those worrying about risk of cancer is significantly higher in the younger group (71% vs 24%). Most patients (n = 24, 75%) have had surveillance endoscopy within the past 2 years.

LIMITATIONS

This study is limited by study generalizability, selection bias, and small sample size.

CONCLUSIONS

Twelve years after colectomy more than half of the patients have favorable bowel function. The rate of incontinence is high, especially among younger patients who have had a shorter time since surgery. Patients with incontinence reported lower psychosocial functioning, are very concerned about their cancer risk, and experience greater distress. This subgroup would benefit from added psychological interventions to enhance coping with familial adenomatous polyposis and surgery.

Surveillance for hereditary cancer: does the benefit outweigh the psychological burden?--A systematic review

Individuals at risk for developing hereditary cancer are offered surveillance in order to improve the prognosis. An important question is whether the benefit of surveillance outweighs the psychological burden. In this review, we evaluated all studies that investigated psychological distress and the quality of life in individuals under surveillance for hereditary cancer of the breast, ovarian, prostate, pancreas, colorectum, melanoma, and various rare syndromes such as familial adenomatous polyposis, Li-Fraumeni and Peutz-Jeghers syndrome. Thirty-two studies were identified. Surveillance for most hereditary cancers was associated with good psychological outcomes. However, surveillance of individuals at high risk for developing multiple tumors appeared to be associated with increased distress and a lower quality of life. Common factors associated with worse psychological outcomes included a personal history of cancer, female gender, having a first degree relative with cancer, negative illness perceptions and coping style. The use of a simple screening tool to identify distressed individuals is recommended.

Evaluation of guidelines for management of familial adenomatous polyposis in a multicenter pediatric cohort

OBJECTIVE

To retrospectively assess, in a pediatric multicenter cohort, guidelines for the management of familial adenomatous polyposis (FAP).

METHODS

Ten centers from the French-speaking Pediatric Gastroenterology Hepatology and Nutrition Group provided follow-up data on patients up to 18 years of age. Clinical records, genetic test results, endoscopy with histopathology examination, and therapeutic modalities were reviewed.

RESULTS

A total of 70 children from 47 families were included. When initial consultation resulted from a surveillance program because of an affected family member, 12 of 59 children were already symptomatic. Among 11 patients whose initial consultation was based only on symptoms, families were unaware at the time of a familial FAP history for 7 children, whereas only 4 cases were sporadic. A panel of 27 different pathogenic adenomatous polyposis coli (APC) germ-line mutations and large genomic deletions were identified in 43 families. Extracolonic manifestations were found in half of the patients. As part of the standard practice for initial screening, the entire cohort underwent colonoscopy, which revealed adenoma above an intact rectosigmoid in 8 cases. Prophylactic colectomy was performed in 42 cases; high-grade dysplastic adenoma and 1 invasive carcinoma were detected in 6 children. For timing of surgery, indications were in accordance with recent international guidelines.

CONCLUSIONS

Defining optimal screening and therapeutic modalities in pediatric FAP cohorts is a challenge. Specific advice for genetic screening, endoscopy surveillance, and type of surgery based on recent guidelines is recommended.

Disclosing individual CDKN2A research results to melanoma survivors: interest, impact, and demands on researchers

BACKGROUND

Whether to return individual research results from cancer genetics studies is widely debated, but little is known about how participants respond to results disclosure or about its time and cost burdens on investigators.

METHODS

We recontacted participants at one site of a multicenter genetic epidemiologic study regarding their CDKN2A gene test results and implications for melanoma risk. Interested participants were disclosed their results by telephone and followed for 3 months.

RESULTS

Among 39 patients approached, 27 were successfully contacted, and 19 (70% uptake) sought results, including three with mutations. Prior to disclosure, participants endorsed numerous benefits of receiving results (mean=7.7 of 9 posed), including gaining information relevant to their children's disease risk. Mean psychological well-being scores did not change from baseline, and no decreases to melanoma prevention behaviors were noted. Fifty-nine percent of participants reported that disclosure made participation in future research more likely. Preparation for disclosure required 40 minutes and $611 per recontact attempt. An additional 78 minutes and $68 was needed to disclose results.

CONCLUSION

Cancer epidemiology research participants who received their individual genetic research results showed no evidence of psychological harm or false reassurance from disclosure and expressed strong trust in the accuracy of results. Burdens to our investigators were high, but protocols may differ in their demands and disclosure may increase participants' willingness to enroll in future studies.

IMPACT

Providing individual study results to cancer genetics research participants poses potential challenges for investigators, but many participants desire and respond positively to this information.

Points to consider in assessing and appraising predictive genetic tests

The use of predictive genetic tests is expanding rapidly. Given limited health care budgets and few national coverage decisions specifically for genetic tests, evidence of benefits and harms is a key requirement in decision making; however, assessing the benefits and harms of genetic tests raises a number of challenging issues. Frequently, evidence of medical benefits and harms is limited due to practical and ethical limitations of conducting meaningful clinical trials. Also, clinical endpoints frequently do not capture the benefit appropriately because the main purpose of many genetic tests is personal utility of knowing the test results, and costs of the tests and counseling can be insufficient indicators of the total costs of care. This study provides an overview of points to consider for the assessment of benefits and harms from genetic tests in an ethically and economically reflected manner. We discuss whether genetic tests are sufficiently exceptional to warrant exceptional methods for assessment and appraisal.

Family matters: examining a multi-family group intervention for women with BRCA mutations in the scope of genetic counselling

The availability of family-centred services for women genetically at-risk for breast and ovarian cancer (BRCA) due to deleterious genetic mutations is still scarce, despite the distress that these women and their families may experience. This study describes a multi-family group intervention for women who tested positive for BRCA mutations and their families. Methods include a time-limited psycho-educational programme involving educational and support components and consisting of four semi-structured multi-family sessions. Three families (a total of nine people) attended the programme in genetic counselling for hereditary cancers at a Portuguese public hospital. A focus group interview was performed 1 month after the last session to assess both the practical and the psychosocial impacts and to collect suggestions from participants. The present paper focuses on the practical aspects of the intervention, its development and its evaluation. Participants reported that the programme is well-structured and that responds to the needs of patients and their families by improving coping skills and medical awareness in the adaptation to genetic illness. Results reinforce the need to integrate psychosocial and family-oriented interventions in genetic counselling, addressing the holistic experience of hereditary disease. Recommendations for enhancing the services available are provided. The multi-family discussion group, combining educative and supportive services with a family focus, can be successfully adapted in genetic counselling protocols.

Returning individual research results: development of a cancer genetics education and risk communication protocol

The obligations of researchers to disclose clinically and/or personally significant individual research results are highly debated, but few empirical studies have addressed this topic. We describe the development of a protocol for returning research results to participants at one site of a multicenter study of the genetic epidemiology of melanoma. Protocol development involved numerous challenges: (1) deciding whether genotype results merited disclosure; (2) achieving an appropriate format for communicating results; (3) developing education materials; (4) deciding whether to retest samples for additional laboratory validation; (5) identifying and notifying selected participants; and (6) assessing the impact of disclosure. Our experience suggests potential obstacles depending on researcher resources and the design of the parent study, but offers a process by which researchers can responsibly return individual study results and evaluate the impact of disclosure.

Parental attitudes, beliefs, and perceptions about genetic testing for FAP and colorectal cancer surveillance in minors

Familial adenomatous polyposis (FAP) is the second most common hereditary colorectal cancer syndrome and confers a nearly 100% lifetime risk of developing colorectal cancer. Understanding factors that facilitate and inhibit genetic testing and cancer surveillance in children who are members of families affected by FAP will better equip clinicians to clarify misunderstandings and facilitate appropriate care. The aims of this study were to examine parental attitudes and beliefs regarding endoscopic surveillance and genetic testing in minors at risk for developing FAP. This cross-sectional study includes analyses of qualitative and quantitative interview data collected from parents of children with or at risk for FAP. This report includes data from 28 parents with a total of 51 biological children between 10-17 years of age. The parents had a clinical and/or genetic diagnosis of FAP. Most commonly reported facilitators included provider recommendation (surveillance) and personalized medical management (genetic testing). Most commonly reported barriers included lack of provider recommendation (surveillance) and cost (genetic testing).

The Scientific Foundation for personal genomics: recommendations from a National Institutes of Health-Centers for Disease Control and Prevention multidisciplinary workshop

The increasing availability of personal genomic tests has led to discussions about the validity and utility of such tests and the balance of benefits and harms. A multidisciplinary workshop was convened by the National Institutes of Health and the Centers for Disease Control and Prevention to review the scientific foundation for using personal genomics in risk assessment and disease prevention and to develop recommendations for targeted research. The clinical validity and utility of personal genomics is a moving target with rapidly developing discoveries but little translation research to close the gap between discoveries and health impact. Workshop participants made recommendations in five domains: (1) developing and applying scientific standards for assessing personal genomic tests; (2) developing and applying a multidisciplinary research agenda, including observational studies and clinical trials to fill knowledge gaps in clinical validity and utility; (3) enhancing credible knowledge synthesis and information dissemination to clinicians and consumers; (4) linking scientific findings to evidence-based recommendations for use of personal genomics; and (5) assessing how the concept of personal utility can affect health benefits, costs, and risks by developing appropriate metrics for evaluation. To fulfill the promise of personal genomics, a rigorous multidisciplinary research agenda is needed.

Genetic counselling and genetic testing in hereditary gastrointestinal cancer syndromes

Up to 10% of cancers are caused by inherited mutations in single genes. The process of genetic counselling and genetic testing allows for identification of these high-risk individuals and their at risk family members and enrolment into appropriate screening protocols. The medical impact of genetic testing is evidenced by reduced morbidity and mortality, however, the impact on a personal or psychosocial level has been more difficult to evaluate. We present a review of the current literature regarding the role of genetic counselling and testing in the setting of gastrointestinal cancers and explore several related issues including risk perception and risk communication, family communication, psychosocial factors and decision making, and family planning. We also provide guidelines for referral to cancer genetics clinics and for promoting discussions about genetic counselling and genetic testing.

Screening and surveillance recommendations for pediatric gastrointestinal polyposis syndromes

Inherited polyposis syndromes are relatively rare disorders in pediatric gastroenterology practice, even in busy academic settings. It is important, however, for pediatric gastroenterologists to be aware of the serious health risks for children and their families affected by these disorders. The diagnosis of a polyp syndrome is often made in the first or second decade of life, long before the risk of gastrointestinal neoplasia. Pediatric gastroenterologists must be prepared then to offer families predictive genetic screening as well as endoscopic surveillance when appropriately indicated. The current overview is designed to provide general guidelines and, whenever possible, evidence-based recommendations for genetic testing, endoscopic surveillance and other screening approaches for children with inherited gastrointestinal polyposis syndromes. In this presentation, the focus is on screening for neoplastic change and complications in the gastrointestinal tract. It is important to understand that extraintestinal cancers are frequent in some of these disorders and the reader is referred to other authoritative sources for additional information about comprehensive health screening outside the gastrointestinal system.

The FAP self-concept scale (adult form)

Familial Adenomatous Polyposis (FAP) is a dominantly inherited disorder characterized by multiple colorectal adenomas associated with a 100% risk of early colorectal cancer. A diagnosis of FAP may alter a person's self-concept, which in turn may impact on an individual's quality of life and screening behaviors.

PURPOSE

The purpose of the study was to develop and validate a scale for measuring the impact of being diagnosed with FAP on an individual's self-concept.

METHODS

The study was conducted in two phases: Phase (1) Item generation and refinement, and Phase (2) Scale selection and initial validation. Adults age 18 and older.

RESULTS

During Phase 1, scale items were generated through individual interviews and two professionally led focus groups. In Phase 2, 132/200 (66%) participants completed the 41-item candidate scale and a battery of standardized validating measures. The mean age of participants was 48 (12.2) years (range 21-74), 57% were female, 72% were married and 69% were Anglo-Canadian. The study resulted in a 23-item valid and reliable scale, Cronbach's alpha = .92, inter-item correlation = .34, total variance explained = 52.6%, low correlation with social desirability, and expected relationships with the other validating measures. Factor analysis resulted in three subscales representing the dimensions of stigma, self-esteem and mastery.

CONCLUSIONS

A promising new scale for measuring self-concept among adults with FAP has been developed. The instrument has potential use as a clinical screening tool and a research measure that will contribute to the empirical and theoretical literature.
