Psychosocial issues in cancer genetics--current status and future directions

Desire for Children and Distress in Women with Hereditary Cancer Syndromes

The diagnosis of a hereditary cancer syndrome can be psychologically stressful and influence family planning. This study aimed to gain insights into the relationship between the desire for children and the distress of female carriers. Women (N = 255) with different hereditary cancer syndromes were assessed from November 2019 to July 2021 at genetic counseling centers, the centers of the German HBOC-Consortium and the centers of the German HNPCC-Consortium regarding their distress levels with the NCCN Distress Thermometer (DT). The desire for children was measured by self-developed questions. Levels of distress and desire for children were evaluated descriptively. Factors influencing the desire for children and distress were calculated using binary logistic regression: 56% (n = 51) of 18- to 39-year-old participants reported a desire to have children; 70.6% of the carriers with a desire for children indicated a need for advice from their physicians regarding family planning. The diagnosis led 61.5% to postpone the timing of family planning, and the majority (68.8%) opted for an earlier birth. Carriers had higher levels of distress. Younger carriers (p = 0.037) and those living in poorer economic circumstances (p = 0.011) were more distressed. The diagnosis of hereditary cancer syndrome affects family planning. The results emphasize the importance of physicians addressing family planning in their counseling sessions.

Cancer Anxiety Mediates the Association Between Satisfaction With Medical Communication and Psychological Quality of Life After Prophylactic Bilateral Salpingo-Oophorectomy

Background

Prophylactic Bilateral Salpingo-Oophorectomy (PBSO) reduces the risk of developing ovarian cancer. However, the psychological mechanisms that may affect post-surgery Quality of Life (QoL) among patients who underwent PBSO are still largely unknown. Thus, this study aimed at exploring the direct and indirect associations of satisfaction with medical communication and cancer anxiety on post-surgery QoL among women at high risk of developing ovarian cancer.

Method

Fifty-nine women (mean age: 50.64 ± 6.7 years) who underwent PBSO took part in this cross-sectional study, filling out a sociodemographic and clinical questionnaire, a battery of validated psychological measures and an ad hoc developed scale for the assessment of cancer anxiety. We first examined the correlations among all variables of interest, and then tested if cancer anxiety mediated the association between satisfaction with medical communication and post-surgery psychological QoL, controlling both for time from surgery and education.

Results

Post-surgery psychological QoL was unrelated from any sociodemographic or clinical variable. Cancer anxiety had a significant direct negative effect on psychological QoL, while satisfaction with medical communication had a significant positive direct effect on it. Finally, cancer anxiety significantly mediated the association between satisfaction with medical communication and post-surgery psychological QoL.

Discussion

Results suggest that post-surgery psychological QoL of patients who underwent PBSO may be increased with interventions, delivered in a genetic counselling setting, targeting quality of medical communication and cancer anxiety.

Aconselhamento Genético: Análise e Contribuições a partir do Modelo de Aconselhamento Psicológico

O Aconselhamento Genético (AG) constitui um processo de investigação do diagnóstico de doenças genéticas. Este estudo de caso objetivou a análise de um modelo de AG. A coleta de dados foi realizada por meio de entrevista semiestruturada e da observação de uma sessão de AG. Os participantes foram profissionais biomédicos e a consulente de uma criança com diagnóstico de síndrome do duplo Y. Verificou-se que o AG envolve uma relação intersubjetiva complexa. Percebeu-se, nos dois polos da relação – profissional e consulente-familiar –, os aspectos emocionais (angústia, temor, culpas etc.) e defensivos (identificação, racionalização etc.) referidos na literatura das crises vitais. A análise do processo de AG indicou: 1) dissonância entre a teoria do AG e a ação do profissional; 2) fixação (defensiva) ao protocolo do AG; 3) uso de linguagem técnica dificultando contato e acolhimento do consulente; e, 4) tempo de compreender considerado na dimensão cronológica e não lógico. Infere-se que os fatores afetivos (angústia, temor, culpas etc.) e a defesa psíquica (identificação, racionalização) restringiram a comunicação do diagnóstico comprometendo o acolhimento e esclarecimento do contexto vital do consulente. Conclui-se que o modelo de AG poderia se enriquecer com a experiência do modelo de aconselhamento psicológico no que se refere ao manejo de crises vitais e no trabalho em equipes multidisciplinares.

Analysis of patient reports on the referral process to two NSW cancer genetic services

To evaluate trends and associations surrounding patient referral to cancer genetics services in NSW. The specific aims of the questionnaire used to collect information were to: (1) quantify the types of cancers being referred, (2) identify the source of referral for the patients, (3) categorise the referral as being either sought by the patient or suggested by the doctor, (4) quantify how often family history was asked, (5) determine who first raised the topic of family history, (6) identify any discouragement faced by patients, (7) clarify the cancer status of patients referred. A comparative patient-reported study was carried out using a questionnaire as the data collection tool in structured short interviews. The questions were aimed at eliciting the patient's understanding of why they were referred to the clinic, whether family history was discussed at the time of referral and who raised the issue via a series of YES/NO and open response questions. Data were collected from March 2012 to August 2012 from two different clinics, St Vincent's Hereditary Cancer Clinic, Sydney and the Hunter Family Cancer Service, Newcastle-both in New South Wales, Australia. Written consent was obtained. The study found that specialists were responsible for the majority of the 150 referrals and were more likely to be proactive in referring, as opposed to GPs (Phi and Cramer's V test). Patients reported that at the time of referral their family history was not asked in 13.5 % of cases, despite being significant. In the 131 cases where family history was discussed, it was the patient on approximately 2 in 5 occasions that brought up the topic. The most common types of cancer seen were breast cancer and colorectal. At both services GP referrals were more common then specialist referrals. On three occasions patients sought referral after being notified that the bloods they had collected by their GP for genetic testing were held by the laboratory due to failure to follow protocol. Six patients reported being discouraged to attend when seeking a referral. At the time of referral 58.7 % of patients were considered to be without cancer. Overall, 20 % of patients requested their referral to the cancer genetics clinics. The discussion of family history in the context of familial cancer is key to accurate risk assessment and management advice. Further education of doctors is required as evidenced by the number of patients where family history was not asked and in those patients who had bloods collected by their GP without counselling.

100 years Lynch syndrome: what have we learned about psychosocial issues?

In the care of patients with Lynch Syndrome (LS), a range of psychosocial issues are encountered, which significantly affect patient outcomes. A brief historical background of 'psycho-onco-genetics' (the domain where psychology, oncology and genetics meet) in relation to LS is presented, followed by an overview of important psychosocial issues identified in the past 20 years. The identification of mismatch repair genes in 1993-1994 made possible genetic counseling and testing for patients who had cancer and for potentially high-risk relatives without cancer. At that time, concerns were raised about the potentially negative psychosocial impact of predictive genetic testing. Since 1993, a large number of studies have been conducted to investigate the possible psychosocial benefits and limitations of such testing. This article presents an overview of: the uptake of and motivations for genetic testing, its psychosocial impact (e.g. psychological adaptation, impact on risk perception and self-concept, and concerns about, and experiences of, genetic discrimination), psychological screening instruments, adherence to and decision-making about preventive strategies, family communication, lifestyle changes, reproductive technology utilization, and professional psychosocial support needs of members of families with LS. Finally, challenges for the future are discussed, including population screening and genomic testing.

Sense of coherence and self-concept in Lynch syndrome

Objective

Most individuals who learn about hereditary cancer manage well, but identification of subgroups who find this knowledge burdening would allow psychosocial intervention. The objective of the study was to assess sense of coherence (SOC) in individuals with Lynch syndrome with comparison to a general population and correlation to self-concept.

Methods

A total of 345 individuals with Lynch syndrome completed the 13-item SOC scale and the 20-item Lynch syndrome self-concept scale. SOC scores were compared to a general Danish population and were correlated to self-concept estimates in individuals with Lynch syndrome. Characteristics of subgroups with adverse scores were described.

Results

Individuals with Lynch syndrome reported SOC scores similar to the general population. SOC and self-concept correlated well with a correlation coefficient of −0.51. Subsets with convergent and divergent scores, which may reflect different effects from knowledge about hereditary cancer, were identified.

Conclusion

Individuals with Lynch syndrome report SOC scores similar to the general population. SOC and self-concept correlate well but allow identification of subset who report adverse outcome and may be relevant for targeted intervention.

Communicating cancer risk within an African context: experiences, disclosure patterns and uptake rates following genetic testing for Lynch syndrome

OBJECTIVE

Data pertaining to Lynch syndrome within a developing country are sparse. This study explored the emotional reaction to a mutation-positive test result among a group of individuals from South Africa. As genetic information is not only limited to the individual but extends to the biological family, communication patterns and uptake of testing among at-risk family members was also investigated.

METHODS

Eighty individuals participated in this qualitative interview study.

RESULTS

Eight emotional reactions were observed, of which two were of particular concern: (1) secrecy due to disbelief and (2) interpretation of a mutation-positive result as a cancer diagnosis. Disclosure rates of personal genetic test results were high to family members, but low to general healthcare providers. Disclosing the test result was not always followed by a discussion of implications of the genetic information or availability of predictive testing for at-risk family members. The uptake rate of predictive testing among the participants' siblings and children was 97% and 73.6%, respectively.

CONCLUSION

Awareness of concerning emotional reactions following the delivery of a genetic test result and insight into disclosure patterns, especially the information that is not communicated, will prove beneficial in improving the effectiveness of counselling and management in Lynch syndrome families.

PRACTICE IMPLICATIONS

Implementation of these findings into the PT programme will have a positive effect on the genetic counseling process.

Development and validation of a brief screening instrument for psychosocial risk associated with genetic testing: a pan-Canadian cohort study

OBJECTIVES

To develop a brief, reliable and valid instrument to screen psychosocial risk among those who are undergoing genetic testing for Adult-Onset Hereditary Disease (AOHD).

DESIGN

A prospective two-phase cohort study.

SETTING

5 genetic testing centres for AOHD, such as cancer, Huntington's disease or haemochromatosis, in ambulatory clinics of tertiary hospitals across Canada.

PARTICIPANTS

141 individuals undergoing genetic testing were approached and consented to the instrument development phase of the study (Phase I). The Genetic Psychosocial Risk Instrument (GPRI) developed in Phase I was tested in Phase II for item refinement and validation. A separate cohort of 722 individuals consented to the study, 712 completed the baseline package and 463 completed all follow-up assessments. Most participants were female, at the mid-life stage. Individuals in advanced stages of the illness or with cognitive impairment or a language barrier were excluded.

INTERVENTIONS

Phase I: GPRI items were generated from (1) a review of the literature, (2) input from genetic counsellors and (3) phase I participants. Phase II: further item refinement and validation were conducted with a second cohort of participants who completed the GPRI at baseline and were followed for psychological distress 1-month postgenetic testing results.

PRIMARY AND SECONDARY OUTCOME MEASURES

GPRI, Hamilton Depression Rating Scale (HAM-D), Hamilton Anxiety Rating Scale (HAM-A), Brief Symptom Inventory (BSI) and Impact of Event Scale (IES).

RESULTS

The final 20-item GPRI had a high reliability-Cronbach's α at 0.81. The construct validity was supported by high correlations between GPRI and BSI and IES. The predictive value was demonstrated by a receiver operating characteristic curve of 0.78 plotting GPRI against follow-up assessments using HAM-D and HAM-A.

CONCLUSIONS

With a cut-off score of 50, GPRI identified 84% of participants who displayed distress postgenetic testing results, supporting its potential usefulness in a clinical setting.

Development and preliminary testing of the psychosocial adjustment to hereditary diseases scale

Background

The presence of Lynch syndrome (LS) can bring a lifetime of uncertainty to an entire family as members adjust to living with a high lifetime cancer risk. The research base on how individuals and families adjust to genetic-linked diseases following predictive genetic testing has increased our understanding of short-term impacts but gaps continue to exist in knowledge of important factors that facilitate or impede long-term adjustment. The failure of existing scales to detect psychosocial adjustment challenges in this population has led researchers to question the adequate sensitivity of these instruments. Furthermore, we have limited insight into the role of the family in promoting adjustment.

Methods

The purpose of this study was to develop and initially validate the Psychosocial Adjustment to Hereditary Diseases (PAHD) scale. This scale consists of two subscales, the Burden of Knowing (BK) and Family Connectedness (FC). Items for the two subscales were generated from a qualitative data base and tested in a sample of 243 participants from families with LS.

Results

The Multitrait/Multi-Item Analysis Program-Revised (MAP-R) was used to evaluate the psychometric properties of the PAHD. The findings support the convergent and discriminant validity of the subscales. Construct validity was confirmed by factor analysis and Cronbach’s alpha supported a strong internal consistency for BK (0.83) and FC (0.84).

Conclusion

Preliminary testing suggests that the PAHD is a psychometrically sound scale capable of assessing psychosocial adjustment. We conclude that the PAHD may be a valuable monitoring tool to identify individuals and families who may require therapeutic interventions.

Limited impact on self-concept in individuals with Lynch syndrome; results from a national cohort study

An increasing number of individuals seek genetic counseling and hereby learn about hereditary cancer in the family. Lynch syndrome is associated with an inherited high risk for colorectal and gynecological cancer, but knowledge about how family members at risk perceive their situation is limited. We used the national Danish HNPCC register to collect data on self-concept from 413 individuals with Lynch syndrome. The recently developed Lynch syndrome self-concept scale contains 20 items within two subscales related to stigma-vulnerability and bowel symptom-related anxiety. Significantly higher total scores, indicating a greater impact on self-concept, were reported by females and by individuals with experience from cancer in close relatives, whereas individuals with less formal education scored significantly higher on the stigma and vulnerability subscale. Scores in the upper quartile were more often reported by women (odds ratio 1.8) and by individuals with less education (OR 1.8). This study provides the first extended use of the Lynch syndrome self-concept scale and suggests that the majority of the Danish mutation carriers adapt well to the situation, though knowledge about the increased risk of cancer seem to have a greater impact in females, individuals with less education and those with experience of cancer in close relatives.

Development and validation of an instrument to measure the impact of genetic testing on self-concept in Lynch syndrome

A positive genetic test result may impact on a person's self-concept and affect quality of life. The purpose of the study was to develop a self-concept scale to measure such impact for individuals carrying mutations for a heritable colorectal cancer Lynch syndrome (LS). Two distinct phases were involved: Phase 1 generated specific colorectal self-concept candidate scale items from interviews with eight LS carriers and five genetic counselors, which were added to a previously developed self-concept scale for BRCA1/2 mutation carriers, Phase II had 115 LS carriers complete the candidate scale and a battery of validating measures. A 20-item scale was developed with two dimensions identified through factor analysis: stigma/vulnerability and bowel symptom-related anxiety. The scale showed excellent reliability (Cronbach's α = 0.93), good convergent validity by a high correlation with impact of event scale (r(102) = 0.55, p < 0.001) and Rosenberg self-esteem scale (r(108) = -0.59, p < 0.001), and a low correlation with the Fear questionnaire (r(108) = 0.37, p < 0.001). The scale's performance was stable across participant characteristics. This new scale for measuring self-concept has potential to be used as a clinical tool and as a measure for future studies.

Lynch syndrome: barriers to and facilitators of screening and disease management

Background

Lynch syndrome is a hereditary cancer with confirmed carriers at high risk for colorectal (CRC) and extracolonic cancers. The purpose of the current study was to develop a greater understanding of the factors influencing decisions about disease management post-genetic testing.

Methods

The study used a grounded theory approach to data collection and analysis as part of a multiphase project examining the psychosocial and behavioral impact of predictive DNA testing for Lynch syndrome. Individual and small group interviews were conducted with individuals from 10 families with the MSH2 intron 5 splice site mutation or exon 8 deletion. The data from confirmed carriers (n = 23) were subjected to re-analysis to identify key barriers to and/or facilitators of screening and disease management.

Results

Thematic analysis identified personal, health care provider and health care system factors as dominant barriers to and/or facilitators of managing Lynch syndrome. Person-centered factors reflect risk perceptions and decision-making, and enduring screening/disease management. The perceived knowledge and clinical management skills of health care providers also influenced participation in recommended protocols. The health care system barriers/facilitators are defined in terms of continuity of care and coordination of services among providers.

Conclusions

Individuals with Lynch syndrome often encounter multiple barriers to and facilitators of disease management that go beyond the individual to the provider and health care system levels. The current organization and implementation of health care services are inadequate. A coordinated system of local services capable of providing integrated, efficient health care and follow-up, populated by providers with knowledge of hereditary cancer, is necessary to maintain optimal health.

Barriers to and motivations for physician referral of patients to cancer genetics clinics

Although it is well known that under-referral of colon cancer patients to cancer genetics clinics is a chronic problem, no study has yet examined why physicians may be ordering testing independently rather than referring patients to cancer genetics clinics. The current study explored variables which may impact a physician's preference for ordering testing independently or referring patients to outside cancer genetics experts. An online questionnaire, distributed to the membership of the American College of Gastroenterology and the American Society of Colorectal Surgeons, yielded responses from 298 physicians. Motivations to refer to cancer genetics clinics rather than order testing independently included fear of genetic discrimination and a belief that patients benefit from genetic counseling about the risks, benefits and consequences of testing. These results suggest that in order to increase referrals, genetic counselors must educate physicians about the unique benefits patients receive from participating in genetic counseling.

Distress and psychosocial needs of a heterogeneous high risk familial cancer population

In order to assess the levels of distress and psychosocial support needs of a high risk population, we undertook a study to look at both the objective and subjective levels of distress and the wants and needs of individuals from a high familial cancer risk population. Three hundred and eighteen individuals (160 affected, 158 unaffected) completed several distress and psychosocial needs questionnaires (including the Brief Symptom Inventory-18). Sixty key informants were also surveyed about their perspective on the support needs of this population. In the largely female (90%), largely HBOC syndrome group (approximately 90%), 20% had significant levels of generalized distress, with no significant differences between affected and unaffected individuals. Generalized distress was also not significantly different as a function of mutation status. Individuals who received inconclusive test results, however, were more likely to indicate somatic symptoms of distress. Those individuals who did not have social support were more likely to be those who had never had cancer and who either had a mutation, received inconclusive test results, or were not tested. Key informants were most likely to indicate that patients need more support. These results provide evidence for the importance of establishing regular psychosocial distress screening, including a focus on somatic symptoms, in such high risk populations.

Validation of a self-concept scale for Lynch syndrome in different nationalities

Learning about hereditary cancer may influence an individual's self-concept, which otherwise represents a complex but stable cognitive structure. Recently, a 20-statement self-concept scale, with subscales related to stigma-vulnerability and bowel symptom-related anxiety, was developed for Lynch syndrome. We compared the performance of this scale in 591 mutation carriers from Denmark, Sweden and Canada. Principal component analysis identified two sets of linked statements-the first related to feeling different, isolated and labeled, and the second to concern and worry about bowel changes. The scale performed consistently in the three countries. Minor differences were identified, with guilt about passing on a defective gene and feelings of losing one's privacy being more pronounced among Canadians, whereas Danes more often expressed worries about cancer. Validation of the Lynch syndrome self-concept scale supports its basic structure, identifies dependence between the statements in the subscales and demonstrates its applicability in different Western populations.

Hopefulness predicts resilience after hereditary colorectal cancer genetic testing: a prospective outcome trajectories study

Background -

Genetic testing for hereditary colorectal cancer (HCRC) had significant psychological consequences for test recipients. This prospective longitudinal study investigated the factors that predict psychological resilience in adults undergoing genetic testing for HCRC.

Methods -

A longitudinal study was carried out from April 2003 to August 2006 on Hong Kong Chinese HCRC family members who were recruited and offered genetic testing by the Hereditary Gastrointestinal Cancer Registry to determine psychological outcomes after genetic testing. Self-completed questionnaires were administered immediately before (pre-disclosure baseline) and 2 weeks, 4 months and 1 year after result disclosure. Using validated psychological inventories, the cognitive style of hope was measured at baseline, and the psychological distress of depression and anxiety was measured at all time points.

Results -

Of the 76 participating subjects, 71 individuals (43 men and 28 women; mean age 38.9 ± 9.2 years) from nine FAP and 24 HNPCC families completed the study, including 39 mutated gene carriers. Four patterns of outcome trajectories were created using established norms for the specified outcome measures of depression and anxiety. These included chronic dysfunction (13% and 8.7%), recovery (0% and 4.3%), delayed dysfunction (13% and 15.9%) and resilience (76.8% and 66.7%). Two logistic regression analyses were conducted using hope at baseline to predict resilience, with depression and anxiety employed as outcome indicators. Because of the small number of participants, the chronic dysfunction and delayed dysfunction groups were combined into a non-resilient group for comparison with the resilient group in all subsequent analysis. Because of low frequencies, participants exhibiting a recovery trajectory (n = 3 for anxiety and n = 0 for depression) were excluded from further analysis. Both regression equations were significant. Baseline hope was a significant predictor of a resilience outcome trajectory for depression (B = -0.24, p < 0.01 for depression); and anxiety (B = -0.11, p = 0.05 for anxiety).

Conclusions -

The current findings suggest that hopefulness may predict resilience after HCRC genetic testing in Hong Kong Chinese. Interventions to increase the level of hope may be beneficial to the psychological adjustment of CRC genetic testing recipients.

The BRCA Self-Concept Scale: a new instrument to measure self-concept in BRCA1/2 mutation carriers

Genetic testing for BRCA1/2 has psychosocial impacts including those related to views of personal health, sense of self and identity and body image. The centrality of a person's self-concept in maintaining physical and psychosocial well-being has been well recognized; however, to date research exploring altered self-concept related to carrier knowledge is limited.

OBJECTIVE

The objective of the study was to develop and validate a scale to measure the self-concept among individuals testing positive for BRCA1/2 mutations.

METHODS

The study was conducted in two phases: phase I: item generation and refinement and phase II: scale selection and initial validation. During phase I, scale items were generated through individual interviews and focus groups of women with BRCA1/2 mutations, including women with or without a prior diagnosis of cancer. In phase II items were selected based on several criteria resulting in a 25-item scale, which underwent a reliability analyses and preliminary validation with 115 women. A second sample of 126 women was used to conduct further validation and samples were pooled to conduct factor analysis and the final scale selection.

RESULTS

A 17-item self-concept scale emerged having three factors: stigma, vulnerability and mastery demonstrating evidence for an instrument with promising psychometric properties (total scale alpha=0.90).

CONCLUSIONS

The scale has direct relevance for research in facilitating our understanding of the specific aspects of the self, which are vulnerable to BRCA1/2 testing and which play a role in clinical outcomes, to facilitate the development and specific testing of interventions and may be used as an outcome measure. Specific measurement tools for genetic populations will ultimately assist in the clinical management of these populations.

Distress in couples approached for genetic counseling and BRCA1/2 testing during adjuvant radiotherapy

OBJECTIVE

Breast cancer patients mostly rely on their partners for support in dealing with their cancer diagnosis and treatment. Genetic counseling and BRCA1/2 testing during primary treatment may add to demands made on their partners. This study aimed to gain insight into the extent of psychological distress in partners of recently diagnosed patients and to find factors to help identify couples vulnerable to high psychological distress after an active approach for genetic counseling.

METHODS

Breast cancer patients and their partners (n=110) completed psychological distress measures (HADS and IES) prior to the approach for counseling (T0), after the approach (T1), and after leaving the genetic counseling protocol (T2). Couples not approached for counseling (n=85) completed similar questionnaires.

RESULTS

Partners reported an equal or lower level of distress than patients, with a positive correlation between the two, although partners and patients differed in the course of their distress. Couples approached for genetic counseling did not differ in the level or course of either distress measure from not approached couples. A high baseline distress best predicts long-term high distress in patients and their partners. Younger patients were found to be particularly vulnerable.

CONCLUSIONS

The approach for genetic counseling during adjuvant radiotherapy was not associated with extra psychological distress in partners or patients in the first year following the breast cancer diagnosis. A partner's long-term level of distress was significantly associated with that of the patient. Highly distressed patients with highly distressed partners were most likely to experience high distress in the long term.

Predictors of decision making in families at risk for inherited breast/ovarian cancer

OBJECTIVE

The purpose of this study was to identify factors associated with decision making about inherited cancer risk information within families and determine the interdependence between survivors' and relatives' decision making.

DESIGN

A descriptive, cross-sectional design using a population-based sample of 146 dyads (N = 292) was used. Analyses included multilevel modeling using the Actor-Partner-Interdependence Model.

MAIN OUTCOME MEASURES

Decision making regarding inherited cancer risk information.

RESULTS

Several individual and family factors contributed toward survivors' and female relatives' decision making about inherited cancer risk information. Individual factors included the individual's perceptions of their family communication and cancer history. Family factors included survivors' and family members' age, communication and coping style that influenced the decision making of the other member of the dyad. Cancer worries and a monitoring coping style affected both seeking and avoiding decision making for survivors and relatives.

CONCLUSIONS

In view of the importance of genetic information upon family health outcomes, it is critical to address both individual and family factors that may influence decision making about cancer risk information and surveillance options for all members within the family.

Psycho-social counselling in predictive genetic testing for cancer: the association between number of supportive sessions and client characteristics as assessed by psycho-social workers

Given the increased demand on genetic services, it is important to identify clients who may require relatively more extensive psychosocial support. This paper describes which client characteristics, as assessed in the first psycho-social counselling session, were associated with requiring relatively more psycho-social support (> or = 3 sessions) in the process of predictive testing for cancer. The study population consisted of 244 counselees for hereditary cancer. Data were derived from an electronic data-base, used by psycho-social workers for the systematic registration of relevant details of each counselling session. Data were analysed for two respective groups: (A) patients who had a known mutation in the family and (B) patients with an as yet unknown mutation in the family. Results show that two or more psychosocial sessions were given if the information derived from the first session indicated the client to have childhood experiences with cancer (in group A), to experience the family role and/or the psychological impact as burdensome (in both groups) or to experience the social impact as burdensome (in group B). We conclude that the first assessment by a psychosocial worker already provides valuable information on the psychological support needs of patients. These findings provide insight into possible problem areas for clients dealing with predictive genetic testing.

Psychological Reactions, Quality of Life, and Body Image After Bilateral Prophylactic Mastectomy in Women At High Risk for Breast Cancer: A Prospective 1-Year Follow-Up Study

Purpose

To prospectively evaluate body image, sexuality, emotional reactions (anxiety, depression), and quality of life in a sample of women having increased risk for breast cancer before and 6 months and 1 year after bilateral prophylactic mastectomy (BPM), and to compare preoperative expectations of the operation with postoperative reactions concerning the impact on six areas of the women's lives.

Patients and Methods

A total of 90 of 98 consecutive women who underwent BPM during October 1997 to December 2005 were included. Data were collected by self-administered questionnaires (eg, Hospital Anxiety and Depression scale, Swedish Short Term-36 Health Survey, Body Image Scale, Sexual Activity Questionnaire) before the operation (n = 81), and 6 (n = 71) and 12 months (n = 65) after BPM.

Results

Anxiety decreased over time (P = .0004). No corresponding difference was found for depression. No differences in health-related quality of life over time were found, with one exception. A substantial proportion of the women reported problems with body image 1 year after BPM (eg, self consciousness, 48%; feeling less sexually attractive, 48%; and dissatisfaction with the scars, 44%). Sexual pleasure was rated lower 1-year post-BPM as compared with before operation (P = .005), but no differences over time in habit, discomfort, or activity were found.

Conclusion

No negative effects on anxiety, depression, and quality of life were found. Anxiety and social activities improved. Negative impact on sexuality and body image was reported.

Comparing genetic counseling with non-genetic health care interactions: two of a kind?

OBJECTIVE

Increasingly clinicians other than genetic counselors will advise people with genetic risks. Although some express concerns about this development because of the need for non-genetic clinicians to have additional training, we argue that genetic counseling has more in common with other health care interactions than is generally assumed.

METHODS

In this narrative review we investigate the health communication literature taking the perspective that all provider-patient/client interactions share the following goals: forming a relationship, the exchange of information, decision making, promoting health-related behavior and providing support.

RESULTS

We found that both non-genetic and genetic 'disciplines' endorse an egalitarian relationship, based on a patient-centered approach and both have difficulties with attuning to the patients' agendas and enhancing patient understanding. Shared decision making is increasingly the preferred model for geneticists and non-geneticists alike, and both need skills to constructively discuss patients' risk-reducing behavior and provide emotional support.

CONCLUSION

Rather than developing separate vocabularies and research traditions, the discipline of genetic counseling may benefit by drawing on non-genetic patient-provider interaction research.

PRACTICE IMPLICATIONS

Since geneticists face the same challenges as non-geneticists, medical training should continue to improve basic consultation skills, regardless of whether the consultation involves genetic information.

Who is prone to high levels of distress after prophylactic mastectomy and/or salpingo-ovariectomy?

BACKGROUND

The present study aimed to assess predictors of distress after 'prophylactic mastectomy (PM) and salpingo-ovariectomy (PSO), in order to enable the early identification of patients who could benefit from psychological support.

PATIENTS AND METHODS

General distress and cancer-related distress were assessed in 82 women at increased risk of hereditary breast and/or ovarian cancer undergoing PM and/or PSO, before and 6 and 12 months after prophylactic surgery. Neurotic lability and coping were assessed before surgery.

RESULTS

Cancer-related distress and general distress at both follow-up moments were best explained by the level of cancer-related and general distress at baseline. Being a mutation carrier was predictive of increased cancer-related distress at 6-month follow-up (but not at 12 months), and of lower general distress 12 months after prophylactic surgery. Also, coping by having comforting thoughts was predictive of less cancer-related distress at 6-month follow-up.

CONCLUSIONS

Genetically predisposed women who are at risk of post-surgical distress can be identified using one or more of the predictors found in this study. Exploration of and/or attention to cancer-related distress and coping style before prophylactic surgery may help physicians and psychosocial workers to identify women who might benefit from additional post-surgical support.

Distress and Family Functioning in Oncogenetic Counselling for Hereditary and Familial Breast and/or Ovarian Cancers

We conducted a psychological assessment during oncogenetic counseling for hereditary breast/ovarian cancer. Anxiety and depression were assessed with the HAD scale, and family functioning and satisfaction with FACES III. HAD was administered at baseline (t(1)), at risk communication (t(2)), at genetic test result communication, or at first surveillance in not tested subjects (t(3)); FACES III was administered at baseline only. We analysed a total of 185 questionnaires administered to the 37 subjects studied. Although not pathological, distress was significantly higher at t(2) and t(3) (p = 0.027 and p = 0.039, respectively). Health and marital status were significantly associated with distress. In a disease-free condition, anxiety was higher (p = 0.027) at t(2), and for single status, depression increased from t(1) to t(2) (p = 0.026). Families were perceived to be well functioning, and subjects were satisfied with their families. The data collected in this analysis could help to improve the quality of oncogenetic counselling in clinical practice.

Sentimentos e experiências na vida das mulheres com câncer de mama

Identificar os sentimentos e as experiências relacionados ao câncer de mama torna-se importante para que as pessoas de seu convívio social compreendam essa etapa da vida da mulher. Uma revisão da literatura foi realizada buscando identificar quais são os pensamentos e os sentimentos mais comuns experimentados pelas mulheres depois do diagnóstico de câncer de mama. Foi realizada por meio de busca bibliográfica no LILACS e MEDLINE, e as palavras-chave utilizadas foram: breast, câncer, feeling, female, representações, sentimentos. Conteúdos do câncer foram abordados, como o significado da doença e suas implicações para a vida emocional e social da mulher. Concluiu-se que as experiências relacionadas ao câncer de mama têm um âmbito muito individual, tendo representações diferenciadas para cada mulher.

The course of distress in women at increased risk of breast and ovarian cancer due to an (identified) genetic susceptibility who opt for prophylactic mastectomy and/or salpingo-oophorectomy

The levels and course of psychological distress before and after prophylactic mastectomy (PM) and/or prophylactic salpingo-oophorectomy (PSO) were studied in a group of 78 women. General distress was measured through the hospital anxiety and depression scale (HADS), cancer-related distress using the impact of events scale (IES). Measurement moments were baseline (2-4 weeks prior to prophylactic surgery), and 6 and 12 months post-surgery. After PM, anxiety and cancer-related distress were significantly reduced, whereas no significant changes in distress scores were observed after PSO. At one year after prophylactic surgery, a substantial amount of women remained at clinically relevant increased levels of cancer-related distress and anxiety. We conclude that most women can undergo PM and/or PSO without developing major emotional distress. More research is needed to further define the characteristics of the women who continue to have clinically relevant increased scores after surgery, in order to offer them additional counselling.

Communication and decision-making about seeking inherited cancer risk information: findings from female survivor-relative focus groups

Dramatic advances in cancer genetics and identification of germline mutations in cancer genes such as BRCA1 and BRCA2 have led to new options in genetic risk assessment for families with histories of breast and ovarian cancer. However, little research has been carried out with individuals and their families regarding how cancer risk information is communicated within families and factors that may affect individuals and family members making informed decisions about their health. This study explored participants' knowledge of cancer risk, their perceptions and concerns regarding inherited cancer risk information, family communication patterns, and factors that may affect their decision to learn about inherited cancer risk in their families. Nine focus groups of family dyads were conducted (N=39) consisting of breast or ovarian cancer patients and close female relatives. All transcribed interviews were analyzed using qualitative software. Key findings showed diversity in how families communicated and made decisions about their health, persistent worry for their families, lack of knowledge about inherited cancer, vigilance in watching their health, and barriers present in communicating about genetic risk. Results from this study support inclusion of family members in addressing inherited cancer risk information and contextual family factors critical to consider in potentially high risk families.

A literature review of the psychological impact of genetic testing on breast cancer patients

OBJECTIVE

Easier access and increased awareness results in more referral for genetic testing for hereditary breast cancer in healthy at-risk women and breast cancer patients. To investigate the psychological impact of genetic testing on breast cancer patients, literature pertaining to this group was reviewed.

METHOD

Medline and PsychInfo databases were searched over the period 1995-2004 for studies aimed at breast cancer patients referred for genetic testing. Qualitative and quantitative psychological outcome measures were identified.

RESULTS

Eight papers were identified focusing on women affected by breast cancer and undergoing genetic counseling and DNA testing.

CONCLUSION

Genetic testing does not lead to an increase in psychological distress in breast cancer patients. However, a recent breast cancer diagnosis adds to general and cancer-specific distress prior to genetic counseling and after DNA test disclosure.

PRACTICE IMPLICATIONS

Clinicians need to be aware of possible high psychological distress and additional counseling needs of recently diagnosed breast cancer patients taking part in genetic testing. Further research should focus on patients who decline genetic counseling or receive an inconclusive test result, including age upon and time since diagnosis.

Surveillance behavior and prophylactic surgery after predictive testing for hereditary breast/ovarian cancer

This article describes breast or ovarian cancer surveillance practices and prophylactic surgery involving 34 carriers and 34 noncarriers of a BRCA1/2 mutation within the year after predictive testing. It also evaluates the effect of the predictive test result on cancer screening practices and provides insight into factors important in the decision-making process about health-related behavior. Within the year following predictive testing, 9% (3 of 34) of the carriers decided to have a prophylactic mastectomy. The majority of the carriers was adherent to recommendations regarding regular cancer surveillance following predictive testing. Furthermore, carriers' adherence to clinical breast examination and mammography recommendations significantly increased from pre- to posttest and was significantly higher than noncarriers' utilization after testing. Of the carriers eligible for prophylactic salpingo-oophorectomy, 75% had this operation. All carriers who were advised to have regular surveillance of the ovaries had ovarian ultrasounds. The authors gave major attention to factors playing a part in the decision-making process about health-related behavior.

Predictive Genetic Testing for Hereditary Breast and Ovarian Cancer: Psychological Distress and Illness Representations 1 Year Following Disclosure

This prospective study evaluates emotional functioning and illness representations in 68 unaffected women (34 carriers/34 noncarriers) 1 year after predictive testing for BRCA1/2 mutations when offered within a multidisciplinary approach. Carriers had higher subjective risk perception of breast cancer than noncarriers. Carriers who did not have prophylactic oophorectomy had the highest risk perception of ovarian cancer. No differences were found between carriers and noncarriers regarding perceived seriousness and perceived control of breast and ovarian cancer. Mean levels of distress were within normal ranges. Only few women showed an overall pattern of clinically elevated distress. Cancer-specific distress and state-anxiety significantly decreased in noncarriers from pre- to posttest while general distress remained about the same. There were no significant changes in distress in the group of carriers except for ovarian cancer distress which significantly decreased from pre- to posttest. Our study did not reveal adverse effects of predictive testing when offered in the context of a multidisciplinary approach.

QUOTE-geneca: development of a counselee-centered instrument to measure needs and preferences in genetic counseling for hereditary cancer

Counselees' motives for seeking genetic counseling for hereditary cancer have already been investigated, however not using instruments based on counselees' perspective. In addition, expectations regarding the process of counseling have scarcely been assessed. This article describes the construction and psychometric properties of the QUOTE-gene(ca), a counselee-centered instrument intended to measure needs and preferences in genetic counseling for hereditary cancer. Formulation of the items involved input from counselees and the instrument was derived from a conceptual framework for measuring patient satisfaction. Two-hundred new counselees completed a questionnaire containing the instrument and measures of coping style (TMSI), generalized anxiety (STAI) and cancer-related stress reactions (IES), prior to their first consultation. Results showed that the instrument captures relevant issues of concern with high internal consistency, and was associated, as expected, with validated measures of coping style and distress. Responses showed that major concerns prior to counseling relate to: receiving information about risk and preventive strategies; the procedure of counseling; and preferences on how the interaction with the counselor proceeds. Receiving emotional support and discussing emotional aspects were considered relatively less important. Increasing insight into individual needs may help counselors in better addressing these concerns, potentially increasing the likelihood of successful counseling.

Psychosocial aspects of genetic counseling and testing

OBJECTIVES

To highlight areas where persons who undergo BRCA1/2 mutation testing may benefit from psychosocial or behavioral support and intervention.

DATA SOURCES

Published scientific literature, cal, and research experiences.

CONCLUSION

Key psychosocial areas that deserve attention by clinicians and researchers include: indeterminate or inconclusive test results, selection of risk management strategies in unaffected BRCA1/2 mutation carriers, and genetic testing in minority communities.

IMPLICATIONS FOR NURSING PRACTICE

By addressing the psychosocial issues faced by patients undergoing genetic testing for cancer, nurses have the potential to maximize opportunities for prevention, early detection, and healthy coping.

Health motivation and emotional vigilance in genetic testing for prostate cancer risk

Actual uptake of genetic testing for cancer susceptibility is generally lower than 50%, despite a high initial interest above 80%. As population-based genetic testing for cancer susceptibility becomes more widespread, there will be an increasing need to understand the relationship of patient-affective factors to test intention and actual uptake behavior. Using hypothetical genetic testing for prostate cancer susceptibility as an example, we used surveys of 400 men in the general population of Philadelphia to develop a Structural Equation Modeling diagram to reveal the influence of affective factors implicated in the intention to undergo genetic testing for prostate cancer risk. Results showed that most men want genetic testing for prostate cancer, believe strongly in its benefits, and are not deterred by negative affect. Our data suggest that high positive expectations, plus a high desire to comply with physician and family suggestions, result in an increased test intention. Informed consent assessment, therefore, requires an appreciation not only of patient risk, but awareness of patient motivation and affect as well.

Effect of a computer-based decision aid on knowledge, perceptions, and intentions about genetic testing for breast cancer susceptibility: a randomized controlled trial

CONTEXT

As the availability of and demand for genetic testing for hereditary cancers increases in primary care and other clinical settings, alternative or adjunct educational methods to traditional genetic counseling will be needed.

OBJECTIVE

To compare the effectiveness of a computer-based decision aid with standard genetic counseling for educating women about BRCA1 and BRCA2 genetic testing.

DESIGN

Randomized controlled trial conducted from May 2000 to September 2002.

SETTING AND PARTICIPANTS

Outpatient clinics offering cancer genetic counseling at 6 US medical centers enrolled 211 women with personal or family histories of breast cancer.

INTERVENTIONS

Standard one-on-one genetic counseling (n = 105) or education by a computer program followed by genetic counseling (n = 106).

MAIN OUTCOME MEASURES

Participants' knowledge, risk perception, intention to undergo genetic testing, decisional conflict, satisfaction with decision, anxiety, and satisfaction with the intervention. Counselor group measures were administered at baseline and after counseling. Computer group measures were administered at baseline, after computer use, and after counseling. Testing decisions were assessed at 1 and 6 months. Outcomes were analyzed by high vs low risk of carrying a BRCA1 or BRCA2 mutation.

RESULTS

Both groups had comparable demographics, prior computer experience, medical literacy, and baseline knowledge of breast cancer and genetic testing, and both counseling and computer use were rated highly. Knowledge scores increased in both groups (P<.001) regardless of risk status, and change in knowledge was greater in the computer group compared with the counselor group (P =.03) among women at low risk of carrying a mutation. Perception of absolute risk of breast cancer decreased significantly after either intervention among all participants. Intention to undergo testing decreased significantly after either intervention among low-risk but not high-risk women. The counselor group had lower mean scores on a decisional conflict scale (P =.04) and, in low-risk women, higher mean scores on a satisfaction-with-decision scale (P =.001). Mean state anxiety scores were reduced by counseling but were within normal ranges for both groups at baseline and after either intervention, regardless of risk status.

CONCLUSIONS

An interactive computer program was more effective than standard genetic counseling for increasing knowledge of breast cancer and genetic testing among women at low risk of carrying a BRCA1 or BRCA2 mutation. However, genetic counseling was more effective than the computer at reducing women's anxiety and facilitating more accurate risk perceptions. These results suggest that this computer program has the potential to stand alone as an educational intervention for low-risk women but should be used as a supplement to genetic counseling for those at high risk.
