Prevalence and detection of psychosocial problems in cancer genetic counseling.

Only a minority of individuals who undergo cancer genetic counseling experience heightened levels of psychological distress, but many more experience a range of cancer genetic-specific psychosocial problems. The aim of this study was to estimate the prevalence of such psychosocial problems, and to identify possible demographic and clinical variables associated significantly with them. Consenting individuals scheduled to undergo cancer genetic counseling completed the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire, the Hospital Anxiety and Depression Scale (HADS) and the Distress Thermometer (DT) prior to or immediately following their counseling session. More than half of the 137 participants reported problems on three or more domains of the PAHC, most often in the domains 'living with cancer' (84%), 'family issues' (46%), 'hereditary predisposition' (45%), and 'child-related issues' (42%). Correlations between the PAHC, the HADS and the DT were low. Previous contact with a psychosocial worker, and having a personal history of cancer were associated significantly with HADS scores, but explained little variance (9%). No background variables were associated significantly with the DT. Previous contact with a psychosocial worker, and having children were significantly associated with several PAHC domains, again explaining only a small percentage of the variance (2-14%). The majority of counselees experience specific cancer genetic counseling-related psychosocial problems. Only a few background variables are associated significantly with distress or psychosocial problems. Thus we recommend using the PAHC or a similar problem-oriented questionnaire routinely in cancer genetic counseling to identify individuals with such problems.

Routine assessment of psychosocial problems after cancer genetic counseling: results from a randomized controlled trial.

Approximately 70% of counselees undergoing cancer genetic counseling and testing (CGCT) experience some degree of CGCT-related psychosocial problems. We evaluated the efficacy of an intervention designed to increase detection and management of problems 4 weeks after completion of CGCT. In this randomized, controlled trial, 118 participants completed a CGCT-related problem questionnaire prior to an - audiotaped - telephone session with their counselor 1 month after DNA-test disclosure. For those randomized to the intervention group (n = 63), a summary of the questionnaire results was provided to the counselor prior to the telephone session. Primary outcomes were discussion of the problems, counselors' awareness of problems, and problem management. Secondary outcomes included self-reported distress, cancer worries, CGCT-related problems, and satisfaction. Counselors who received a summary of the questionnaire were more aware of counselees' problems in only one psychosocial domain (practical issues). No significant differences in the number of problems discussed, in problem management, or on any of the secondary outcomes were observed. The prevalence of problems was generally low. The telephone session, combined with feedback on psychosocial problems, has minimal impact. The low prevalence of psychosocial problems 1 month post-CGCT recommends against its use as a routine extension of the CGCT procedure.

Impact of rapid genetic counselling and testing on the decision to undergo immediate or delayed prophylactic mastectomy in newly diagnosed breast cancer patients: findings from a randomised controlled trial.

BACKGROUND: Female breast cancer patients with a BRCA1/2 mutation have an increased risk of contralateral breast cancer. We investigated the effect of rapid genetic counselling and testing (RGCT) on choice of surgery. METHODS: Newly diagnosed breast cancer patients with at least a 10% risk of a BRCA1/2 mutation were randomised to an intervention group (offer of RGCT) or a control group (usual care; ratio 2 : 1). Primary study outcomes were uptake of direct bilateral mastectomy (BLM) and delayed contralateral prophylactic mastectomy (CPM). RESULTS: Between 2008 and 2010, we recruited 265 women. On the basis of intention-to-treat analyses, no significant group differences were observed in percentage of patients opting for a direct BLM (14.6% for the RGCT group vs 9.2% for the control group; odds ratio (OR) 2.31; confidence interval (CI) 0.92-5.81; P=0.08) or for a delayed CPM (4.5% for the RGCT group vs 5.7% for the control group; OR 0.89; CI 0.27-2.90; P=0.84). Per-protocol analysis indicated that patients who received DNA test results before surgery (59 out of 178 women in the RGCT group) opted for direct BLM significantly more often than patients who received usual care (22% vs 9.2%; OR 3.09, CI 1.15-8.31, P=0.03). INTERPRETATION: Although the large majority of patients in the intervention group underwent rapid genetic counselling, only a minority received DNA test results before surgery. This may explain why offering RGCT yielded only marginally significant differences in uptake of BLM. As patients who received DNA test results before surgery were more likely to undergo BLM, we hypothesise that when DNA test results are made routinely available pre-surgery, they will have a more significant role in surgical treatment decisions.

Psychosocial aspects of hereditary cancer (PAHC) questionnaire: development and testing of a screening questionnaire for use in clinical cancer genetics.

BACKGROUND: Up to three-quarters of individuals who undergo cancer genetic counseling and testing report psychosocial problems specifically related to that setting. The objectives of this study were to develop and evaluate the screening properties of a questionnaire designed to assess specific psychosocial problems related to cancer genetic counseling. METHODS: We adopted the European Organisation for Research and Treatment of Cancer Quality of Life Group guidelines to develop the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire, a 26-item questionnaire organized into six problem domains: genetics, practical issues, family, living with cancer, emotions, and children. The Distress Thermometer and a question per domain on the perceived need for extra psychosocial services were included as well. We administered the questionnaire and the Hospital Anxiety and Depression Scale to 127 counselees at the time of genetic counseling and 3 weeks after DNA test disclosure. As a gold standard to evaluate the screening properties of the questionnaire, participants underwent a semi-structured interview with an experienced social worker who assessed the presence and severity of problems per domain. RESULTS: A cutoff score representing responses of 'quite a bit' or 'very much' to one or more items within a given problem domain yielded moderate to high sensitivity across domains. A cutoff of 4 on the Distress Thermometer yielded high sensitivity. The questions regarding the perceived need for extra psychosocial services yielded high specificity and negative predictive values. CONCLUSION: The Psychosocial Aspects of Hereditary Cancer questionnaire in combination with the Distress Thermometer can be used as a first-line screener for psychosocial problems within the cancer genetic counseling setting.

[DNA-based diagnosis of hereditary tumour predisposition]. / DNA-diagnostiek naar erfelijke aanleg voor tumoren.

Of all forms of cancer, approximately 5% are caused by factors leading to a strong genetic predisposition. DNA diagnosis is currently used in families with hereditary tumour syndromes, such as familial adenomatous polyposis, hereditary non-polyposis colorectal carcinoma (Lynch syndrome), and hereditary breast and ovarian cancer. Those persons who have not inherited the predisposition no longer have to undergo regular examinations. DNA diagnosis for a hereditary predisposition is currently also performed in patients with cancer at a relatively young age, even if the family history is unclear or negative. Consideration of the patient in the context of his or her family is important for both medico-technical and psychosocial reasons. This is true of both diagnostic and presymptomatic DNA diagnosis. For these reasons, the clinical application of the DNA diagnosis of hereditary tumours has become an integral part of the work of the multidisciplinary cancer family clinics of the university medical centres and the cancer centres. Guidelines for the management of hereditary tumours have recently been issued, with criteria for referral to the specialised outpatient clinics.

Sexual outcomes following treatment for early-stage gynecological cancer: a prospective and cross-sectional multi-center study.

This study evaluates the impact of early-stage gynecological cancer and its treatment on sexuality and assessed needs for care regarding sexual rehabilitation. Data from 58 women from a prospective, longitudinal study were compared to data from 220 women from a cross-sectional study. Patients in the prospective study completed questionnaires prior to treatment and then 6 and 12 months post-treatment. A single assessment was obtained from patients in the cross-sectional study. All women had a partner. Both groups were comparable on important independent variables. Both samples had an equal level of sexual contact, but participants in the cross-sectional study (mean time 46 months post-treatment) reported a higher frequency of sexual problems, were more troubled by those problems and reported a lower sexual satisfaction. However, in both groups the level of the reported dysfunctions was relatively low. Around 80% of the patients were satisfied with the information provided on sexual rehabilitation. Little need for extra care on sexual rehabilitation was reported. In conclusion, women with early-stage gynecological cancer were not especially prone to severe sexual problems and seemed to cope well with the consequences of cancer and its treatment on their sexual lives. It was suggested that this relatively positive outcome is a result of the improved patient care and education on sexual aspects in the last decade.

Sexual outcomes following treatment for early stage gynecological cancer: a prospective multicenter study.

Data are presented of a prospective, longitudinal study on the impact of early stage gynecological cancer on sexuality. Women with a partner (n = 58) completed self-report questionnaires following diagnosis but prior to treatment and then at 6 and 12 months post-treatment. A single assessment was also obtained from a healthy comparison group (n = 103). Pre-treatment cancer patients reported fewer and less trouble with sexual problems compared to healthy controls. Neither sexual satisfaction nor sexual activity changed from pre- to post-treatment and was comparable to that of healthy controls. Post-treatment, relatively minor sexual difficulties were shown; a notable difficulty for cancer patients concerned lubrication. At 12 months post-treatment, the sexual functioning of cancer patients was comparable to healthy controls.
