Psychiatric and Educational Aspects of Familial Adenomatous Polyposis: A Nationwide Danish Cohort Study With Matched Nonexposed Individuals

INTRODUCTION

Familial adenomatous polyposis (FAP) is an autosomal, dominantly inherited disorder that predisposes to colorectal cancer. An increased risk of cancer may affect mental health, but the magnitude of this effect remains unknown. We assessed the psychosocial functioning, including the educational level attained and risk of psychiatric comorbidity, of patients with FAP by comparing them with matched nonexposed individuals.

METHODS

All Danish patients with FAP diagnosed before April 2021 were identified in the Danish Polyposis Register and paired with 4 matched nonexposed individuals. Educational history, psychiatric contacts or diagnoses ( International Classification of Disease, 10th Revision ), and treatment with antidepressants, anxiolytics, or antipsychotics were compared between patients with FAP and nonexposed individuals.

RESULTS

The analysis included 445 patients with FAP and 1,538 nonexposed individuals. The highest educational level reached was significantly lower for patients with FAP ( P < 0.001). When comparing patients with FAP and nonexposed and adjusting for a cancer diagnosis, an increased risk was observed for a psychiatric contact (1.69, 95% confidence interval [CI] 1.25-2.29, P < 0.001), any psychiatric prescription (1.39, 95% CI 1.17-1.66, P < 0.001), a psychiatric diagnosis (1.64, 95% CI 1.19-2.26, P = 0.002), and experiencing any psychiatric event (hazard ratio 1.42, 95% CI 1.20-1.68, P < 0.001). An increased risk was specifically seen for mood (affective) disorders (1.76, 95% CI 1.09-2.83, P = 0.02) and behavioral and emotional disorders (2.01, 95% CI 1.10-3.69, P = 0.02) and the need for antidepressants (1.59, 95% CI 1.24-2.03, P < 0.001) and antipsychotics (1.85, 95% CI 1.26-2.70, P = 0.002).

DISCUSSION

Compared with nonexposed individuals, patients with had significantly less education and an increased risk of developing mood and behavioral disorders, with an increased likelihood of needing antidepressants and antipsychotics.

Surveillance Compliance and Quality of Life Assessment Among Surgical Patients with Familial Adenomatous Polyposis Syndrome

BACKGROUND

Familial adenomatous polyposis (FAP) syndrome has a near-100% lifetime risk of colorectal cancer. Early surveillance and prophylactic surgery have been advocated to reduce this risk. However, the surveillance practices among FAP individuals in Saudi Arabia are unknown. We aimed to explore surveillance compliance in our population, as well as the disease impact on their quality of life (QoL).

METHODS

All patients with FAP who underwent surgical resection at King Saud University Medical City between 2016 and 2022 were included. Demographic data, clinical features, family history, and compliance with surveillance were collected and analyzed. QoL questionnaires: Short-form health survey (SF-36) and European Organization for Research and Treatment (EORTC) were conducted by phone interview.

RESULTS

A total of 14 patients were included with an average age of 25 years. Three patients (21.4%) were the first of their family members to develop FAP. Nine patients (64%) were untested for genetic mutation due to lack of referral to geneticists. The compliance rate toward both pre-operative colonoscopy and upper endoscopy were 78%. However, 38% and 27% compliance rates were observed toward initial and post-operative colonoscopy, respectively. The compliance rate was 14% toward thyroid ultrasound. QoL scores varied among patients, with a mean score above 60 across all SF-36 domains.

CONCLUSION

An overall poor compliance was observed among our participants, particularly toward thyroid ultrasound. Increased health awareness and patient education are essential. In addition, the importance of surveillance and genetic counseling should be emphasized among physicians treating these patients.

Psychological implications of living with familial adenomatous polyposis

BACKGROUND AND STUDY AIMS

Psychosocial implications of living with FAP remain largely unexplored. This article reviews available literature on three topics: 1) Implications of living with FAP 2) genetic testing and reproductive decision-making and 3) family communication.

PATIENTS AND METHODS

Papers published until 2009 about psychosocial and behavioral issues in FAP were identified.

RESULTS

Psychometric data indicate that FAP patients and at-risk relatives as a group do not exhibit clinical symptoms of mental health problems after clinical or genetic diagnosis. However, some subgroups revealed to be more vulnerable to distress. Also, concerns related to the disease and its consequences were reported. While interest in prenatal diagnosis or preimplantation genetic diagnosis seems to be high it is important to study actual uptake because this may reveal to be much lower. Family members are an important source of information and the few available data suggest that family communication is problematic. The findings described have several shortcomings. They were obtained from only a few studies often conducted using specific or mixed study groups, originating from the 90ties and mostly cross-sectional in nature.

CONCLUSIONS

For clinical practice, it is important to have more research data on how FAP patients at different ages cope with the disease, on the impact of genetic testing on reproductive decision-making and on family communication. Results reported here need to be confirmed by additional research and new themes need to be explored.

Impact of familial adenomatous polyposis on young adults: quality of life outcomes

PURPOSE

This study used a novel questionnaire to assess quality of life and psychologic adjustment among young adults aged 18 to 35 years with a diagnosis of, or at risk of, developing familial adenomatous polyposis.

METHODS

Eighty-eight participants (25 males) were recruited through four Australian Hereditary Bowel Cancer Registries.

RESULTS

The average age of participants was 28 years, and the average age of these participants at the time of their last genetic consultation was 23 years. Seventy-one participants (81 percent) had clinical familial adenomatous polyposis, of whom 57 had undergone an ileorectal anastomosis or formation of an ileal pouch with anal anastomosis to prevent colorectal cancer. The ileal-pouch-with-anal-anastomosis group had significantly more adverse outcomes for physical functioning, body image, sexual impact, and negative affect compared with the no-surgery group -- and significantly more negative outcomes for physical functioning and negative affect compared with the ileorectal-anastomosis group. Among the total sample, a small proportion (11.4 percent) had avoidance scores indicative of a significant stress response, and being single was associated with higher levels of avoidance responses about familial adenomatous polyposis (z = -3.19; P = 0.001).

CONCLUSIONS

Familial adenomatous polyposis may have a negative impact across a broad range of life domains. Being single is an important risk factor for adverse psychologic outcomes. Delaying surgery, especially ileal pouch with anal anastomosis may minimize the negative impact on physical and psychologic functioning. Referral for psychologic intervention may be required for a small proportion of those affected by familial adenomatous polyposis, and ongoing access to genetic services may help to identify and address the needs of this group.

Impact of familial adenomatous polyposis on young adults: attitudes toward genetic testing, support, and information needs

PURPOSE

The study assessed views concerning genetic testing and information and support needs among young adults aged 18 to 35 years with a diagnosis of or at risk of developing familial adenomatous polyposis.

METHODS

A total of 88 participants were recruited through Hereditary Bowel Cancer Registries and assessed using self-administered questionnaires.

RESULTS

The average age of participants was 28 years, and the average age at the time of their last genetic consultation was 23 years. Although 75% would consider prenatal genetic testing, only 21% would consider termination of an affected pregnancy. Sixty-one percent selected "at birth" or "early childhood" as the preferred age for genetic testing of offspring. Participants' highest areas of unmet support needs were with regard to anxiety about their children having familial adenomatous polyposis (39%) and fear of developing cancer (28%).

CONCLUSION

The parental desire to test children before it is clinically indicated may be a source of distress and create conflict with genetic services. These findings demonstrate that familial adenomatous polyposis may significantly impact young adults, with many having unmet support needs. The length of time since the last genetic consultation and the young age at which these consultations took place suggest that clinics should consider a means of regular follow-up to address these unmet needs.

Self-Surveillance for Genetic Predisposition to Cancer: Behaviors and Emotions

PURPOSE/OBJECTIVES

To describe the kinds of self-monitoring activities and the emotional responses associated with those activities in patients with a genetic predisposition to multiple endocrine neoplasia type 2a (MEN2a) or familial adenomatous polyposis (FAP).

RESEARCH APPROACH

Thematic analysis of the transcripts of patient interviews conducted for two previous grounded theory investigations of participation in lifelong surveillance for patients with cancer predisposition syndromes and their family members.

SETTING

In the original studies, participants were recruited through a high-risk gastrointestinal cancer clinic (for FAP) and pediatric and adult endocrinology clinics (for MEN2a) at two eastern U.S. medical centers and by patient referral.

PARTICIPANTS

58 transcripts of interviews with 29 patients; 17 diagnosed with FAP or the variants of Gardner syndrome and attenuated FAP and 12 patients diagnosed with MEN2a.

METHODOLOGIC APPROACH

Informants participated in two hour-long, in-depth interviews and completed a self-administered sociodemographic questionnaire.

MAIN RESEARCH VARIABLES

Types of self-surveillance activities.

FINDINGS

Patients engage in an elaborate set of self-surveillance activities that are grouped into five categories of behavior: Medication Appraisal, Phenotype Tracking, Intake and Output Monitoring, Laboratory and Treatment Recording, and Tracking of Visits. Self-surveillance behaviors are grouped independent of type of syndrome, penetrance, age, or gender of the patient. Each category comprises a variety of behaviors that correspond with treatment recommendations and understanding of the disorder.

CONCLUSIONS

Self-surveillance may be driven by a combination of anticipation and the need for control and understanding.

INTERPRETATION

Findings from the study could be used to create an assessment tool to evaluate the extent to which patients are involved in day-to-day self-monitoring. Clinicians may use the categories to better understand patients' knowledge deficits and the emotional impact of enhanced vigilance. Self-surveillance activities performed by patients with MEN2a and FAP also may be performed by patients with other cancer predisposition syndromes.

Quality of life in adults diagnosed with familial adenomatous polyposis and desmoid tumor

PURPOSE

The purpose of this study was to examine the health-related quality of life in a sample of Canadian adults diagnosed with familial adenomatous polyposis and desmoid tumor.

METHODS

The study was conducted in two parts. Seven individuals participated in a focus group prior to a mail-out survey. A cross-sectional mail-out survey was administered to eligible individuals who were actively followed at the Familial Gastrointestinal Cancer Registry at Mount Sinai Hospital.

RESULTS

Forty-one individuals (25 female and 16 male) were available to be contacted by the registry coordinator and 23 questionnaire packages were completed, resulting in a 56.1 percent participation rate. The results of this study demonstrated a reduced health-related quality of life for individuals living with familial adenomatous polyposis and desmoid tumor for over 10 years. The main predictors of health-related quality of life in this analysis included marital status (married vs. not married), prior knowledge of desmoid tumor in the family, and current level of hopelessness (R(2) = 0.856, df = 13, F = 26.8, P < 0.001). The qualitative content analysis of themes from the focus group indicated that ongoing medical uncertainty and lack of information from health care professionals, isolation, and family communication were the main challenges in living with desmoid tumors.

CONCLUSIONS

The findings from this study suggest that ongoing education of health care professionals is warranted and that information and support interventions may be beneficial to this clinical population.

Predictive genetic testing in children and adults: a study of emotional impact

AIM

To determine whether, following predictive genetic testing for familial adenomatous polyposis (FAP), children or adults receiving positive results experience clinically significant levels of anxiety or depression, and whether children receiving positive results experience higher levels of anxiety or depression than adults receiving positive results.

DESIGN

Two studies, one cross sectional and one prospective.

SAMPLE

208 unaffected subjects (148 adults and 60 children) at risk for FAP who have undergone genetic testing since 1990.

MAIN MEASURES

DEPENDENT VARIABLES

anxiety, depression; independent variables: test results, demographic measures, psychological resources (optimism, self-esteem).

RESULTS

Study 1. In children receiving positive results, mean scores for anxiety and depression were within the normal range. There was a trend for children receiving positive results to be more anxious and depressed than those receiving negative results. In adults, mean scores for anxiety were within the normal range for those receiving negative results, but were in the clinical range for those receiving positive results, with 43% (95% CI 23-65) of the latter having scores in this range. Regardless of test result, adults were more likely to be clinically anxious if they were low in optimism or self-esteem. Children receiving positive or negative results did not experience greater anxiety or depression than adults. Study 2. For children receiving a positive test result, mean scores for anxiety, depression, and self-esteem were unchanged over the year following the result, while mean anxiety scores decreased and self-esteem increased after receipt of a negative test result over the same period of time.

CONCLUSION

Children, as a group, did not show clinically significant distress over the first year following predictive genetic testing. Adults were more likely to be clinically anxious if they received a positive result or were low in optimism or self-esteem, with interacting effects. The association between anxiety, self-esteem, and optimism suggests that counselling should be targeted, not only at those with positive test results, but also at those low in psychological resources.

Hereditary cancers in children and ethical and psychosocial implications

This article describes the application of genetic testing of children for hereditary cancers and the resultant ethical and psychosocial implications. Basic cancer genetics concepts are reviewed. Specific hereditary cancers that may affect children are described along with case examples and recommendations for nursing practice.

Genetic predictive testing for bowel cancer predisposition: the impact on the individual

When considering the impact of a genetic diagnosis of hereditary predisposition to colon cancer, there are many similarities to other predictive genetic tests, but also many differences. The development and availability of such genetic diagnoses, and the concept of testing being linked to effective prevention, have advanced rapidly, opening up not only unique opportunities but also unique psychosocial situations for the affected families-and unusual ethical issues for the professional. Compared to a diagnosis of sporadic colorectal cancer for a patient, hereditary colorectal cancer requires an understanding of genetics, heredity, and the attendant mathematics of risk calculation, but, most importantly, there must be a belief that it is possible to remain healthy whilst having an increased risk. This paper outlines the possible impact of a genetic diagnosis of hereditary non-polyposis colorectal cancer (HNPCC) or familial adenomatous polyposis (FAP) on both the individual and the family and concludes that genetic testing should be accompanied by genetic counseling. Relevant ethical issues are also introduced, with the opinion presented suggesting that if primary considerations are always for the individual rather than the family or society, then unethical or eugenic decisions are likely to be avoided.

Distress in individuals facing predictive DNA testing for autosomal dominant late-onset disorders: comparing questionnaire results with in-depth interviews. Rotterdam/Leiden Genetics Workgroup

In 50% risk carriers for Huntington disease (n = 41), hereditary cerebral hemorrhage with amyloidosis Dutch-type (n = 9) familial adenomatous polyposis coli (n = 45) and hereditary breast and ovarian cancer (n = 24), pretest intrusion and avoidance (Impact of Event Scale), anxiety and depression (Hospital Anxiety and Depression Scale), feelings of hopelessness (Beck Hopelessness Scale), and psychological complaints (Symptom Checklist) were assessed to determine their psychological well-being. The manner of discussing the genetic disorder, the test, and its implications during a semistructured interview (reflecting on one's emotions without getting carried away or dismissing or minimizing the subject) was judged in terms of coherence. Participants at risk for neurodegenerative disorders had higher anxiety and depression scores and more psychological complaints than did those at risk for cancer syndromes. Those reporting high intrusion/high avoidance had higher anxiety and depression scores and more psychological complaints than did those reporting low intrusion/low avoidance. However, the scoring of the interview showed that participants reporting high intrusion/high avoidance were more reflective about their emotions without getting carried away or dismissing the subject (e.g., more coherent) than those reporting low intrusion/low avoidance. This result suggests that participants with higher stress scores may be actively dealing with the emotional implications of the test, whereas those with low stress scores may (as yet) be unable to face these implications. It is important to identify the strategy of coping with threat to provide suitable counseling and necessary guidance. However, long-term follow-up is needed to learn the consequences of a denial coping strategy for those participating in a genetic testing program.

Genetic testing for cancer in children. Short-term psychological effect

OBJECTIVE

To study the psychological effect of genetic testing in children.

DESIGN

We evaluated the psychological effect of predictive genetic testing through surveys of children at risk for familial adenomatous polyposis. Their psychological state was assessed before testing and 3 months later.

SETTING

A research clinic.

PARTICIPANTS

A volunteer sample of 41 children, aged 6 to 16 years, and their parents.

MAIN OUTCOME MEASURES

Self-report inventories of depression, anxiety, behavior problems, and competence.

RESULTS

Nineteen children were found to have a gene mutation (mutation-positive) and 22 did not (mutation-negative). Their depression, anxiety, and behavior problem and competence scores remained in the normal range after testing. Also, parents' depression scores remained within normal limits at follow-up. There were subclinical changes, however. Mutation-positive children with affected mothers had significantly higher depression scores at follow-up. Also, regardless of test results, children with affected mothers had significantly increased anxiety scores after testing. In families with mutation-positive and mutation-negative children, familial adenomatous polyposis-unaffected parents experienced significantly increased depressive symptoms at follow-up.

CONCLUSIONS

Predictive testing of children at risk for familial adenomatous polyposis did not lead to clinically significant psychological symptoms in tested children or their parents. However, it is premature to conclude that long-term follow-up will be equally favorable. Additional study will be needed to determine the families' understanding of the genetic information and the effect of the information on familial relationships.

Genetic counseling in an extended attenauted familial adenomatous polyposis kindred

OBJECTIVES

To provide DNA-based genetic counseling to family members in the direct genetic lineage of a family fulfilling phenotypical criteria for the autosomal, dominantly inherited, attenuated familial adenomatous polyp (AFAP) syndrome. This enabled highly targeted cancer risk estimation based on cancer phenotype in concert with the presence or absence of the adenomatous polyposis coli (APC) germline mutation. Management recommendations could then be fully responsive to this syndrome's natural history.

METHODS

Detailed family history with pathology verification of colonic polyps and cancer was performed on an extended AFAP kindred. Endoscopic gastrointestinal examinations enabled detailed knowledge of the syndrome's upper and lower gastrointestinal tract phenotype. Molecular genetic evaluation of DNA led to the identification of the APC germline mutation which co-segregated with the phenotype.

RESULTS

Forty-two members of this extended AFAP family underwent DNA testing, wherein 27 were found to harbor the APC germline mutation,thereby enabling precision in their genetic counseling. Anecdotal examples of this counseling experience, with particular attention to psychological reactions, as well as concerns about such issues as insurance and employer discrimination, have been described.

CONCLUSIONS

When DNA-based testing is offered to AFAP family members, genetic counselors must compassionately consider patients' psychological concerns when providing detailed risk status and available surveillance and management programs.

Genetic testing and counseling in familial adenomatous polyposis

Testing for adenomatous polyposis coli (APC), the gene responsible for familial adenomatous polyposis (FAP), can now be offered to family members in FAP kindreds. With the availability of this test, genetic counseling has become a crucial tool for helping FAP patients and their relatives understand the syndrome and its implications and for assisting at-risk individuals in making informed decisions about whether or not to undergo genetic testing. Genetic counseling can occur at several time points: when FAP is diagnosed, when an FAP patient is considering reproductive options, when a patient is deciding whether to have his or her children screened, and when an at-risk person is considering genetic testing. Based on our experiences from working with families in a large FAP registry, we explore the different issues that emerge in each of these settings, and how the genetic counselor or clinician can help FAP patients, family members, and at-risk persons deal with these issues.

Quality of life after total proctocolectomy and ileal J-pouch-anal anastomosis

We investigated the daily life and opinions of patients after total proctocolectomy and ileal J-pouch-anal anastomosis. Eighty patients answered a questionnaire, completed Cattell's anxiety scale, and recorded bowel function for one month. Both colitis and polyposis patients defecated five times daily, had 1.6 episodes of nocturnal motions weekly, and soiled twice weekly. However, colitis patients were more satisfied with their bowel function and surgical outcome than were polyposis patients. This difference had a close relationship to the personality factors of ego strength and frustration. All patients with either disease who defecated less than three times daily, had no nocturnal motions, and had no soiling showed normal ego strength and frustration and were completely satisfied with their bowel status and operation. In contrast, patients defecating more than seven times daily or more than once per week nocturnally and soiling more than four times weekly had high frustration and were dissatisfied. Thus, satisfaction with surgery correlated not only with the objective outcome but also with personality and lifestyle.

Coping styles, psychopathology and intellectual performance in patients with familial adenomatous polyposis

Thirty-eight patients with familial adenomatous polyposis (FAP) were compared with 19 patients with ulcerative colitis (UC) for differences in illness-related variables, coping styles, psychiatric symptomatology, and intellectual performance. Patients with FAP had significantly less education, longer time since recent surgery, less psychiatric illness, and evidence of less preoccupation with their illness, as compared with UC patients. FAP patients with a positive family history (N = 28) scored significantly lower on both verbal and performance intellectual tests, even when taking education into account, compared with FAP patients without a family history (N = 9). The relevance of these findings to the ongoing monitoring and surveillance of patients with FAP is discussed.

Counseling families with hereditary gastrointestinal polyposis syndromes

Counseling for families with one of the hereditary polyposis and/or colon cancer syndromes can be offered by a number of different professional persons depending upon the emotional needs of the counselee. It is sometimes difficult to persuade at-risk persons in polyposis families to institute a medical surveillance plan with their physicians because of their reactions to knowledge (or lack of it) of the family diagnosis. Counseling may reveal both emotional and financial problems as deterrents to needed medical planning. Support organizations and explanatory literature are helpful in allaying fears and promoting compliance.

Psychosocial adjustment of familial polyposis patients and participation in a chemoprevention trial

Psychological and social adjustment was assessed in eighty-nine individuals with familial polyposis, a genetically transmitted disease placing one at high risk for colon cancer. Three illness-related concerns were identified: fear about future health due to the high risk for cancer; guilt about transmitting a genetic disease to one's children; and concern about physical disfigurement resulting from surgery. Well-being scores were generally positive, although somewhat lower than those reported in a community sample. Two factors in particular influenced well-being scores: those with higher levels of concern about disfigurement reported lower well-being, and those with accurate information about the disease reported higher well-being. Of the eighty-nine individuals included in this study, sixty-one were participating in a clinical trial and twenty-eight had been invited but declined entry. Demographic and psychosocial factors were examined for their relationship to participation. Only three of these variables, length of time since diagnosis, religious affiliation, and geographic location distinguished participants from nonparticipants.
