Interventions to support patients with sharing genetic test results with at-risk relatives: a synthesis without meta-analysis (SWiM)

Whilst the finding of heritable susceptibility to disease was once relatively rare, mainstreaming of genetic testing has resulted in a steady increase. Patients are often encouraged to share their genetic test results with relevant relatives, but relatives may not receive this information, leaving them without knowledge of their own risk. Therefore, strategies to help communicate such information are important. This review aimed to explore the efficacy of existing interventions to improve the sharing of genetic test results. A synthesis without meta-analysis design was used. A systematic search of Medline, CINAHL, PsychINFO, and AMED was conducted, and five studies were identified worldwide. Data were extracted for each study regarding study aim, participant characteristics, condition, intervention details, comparison, study duration, outcome measures, theory and behaviour change techniques used. Limited efficacy and application of theory was found. Knowledge, motivation and self-efficacy were not increased in any intervention. No gender differences in communication behaviour were encountered in interventions that recruited men and women. Two studies reported an evaluation of acceptability, which showed that the interventions were well received by patients and health professionals. No study reported the involvement of the target population in any phase of intervention development. Given the lack of health psychology-informed interventions in this area of clinical genetics, we recommend genetic health professionals, health psychologists and patients collaborate on all stages of future interventions that involve the cascading of genetic health information within families. We also provide guidance regarding use of theory and intervention elements for future intervention development.

Evaluation of a nationwide Dutch guideline to detect Lynch syndrome in patients with endometrial cancer

OBJECTIVE

In the Netherlands a nationwide guideline was introduced in 2016, which recommended routine Lynch syndrome screening (LSS) for all women with endometrial cancer (EC) <70 years of age. LSS consists of immunohistochemical (IHC) staining for loss of mismatch repair (MMR) protein expression, supplemented with MLH1 methylation analysis if indicated. Test results are evaluated by the treating gynaecologist, who refers eligible patients to a clinical geneticist. We evaluated the implementation of this guideline.

METHODS

From the nation-wide pathology database we selected all women diagnosed with EC < 70 years of age, treated from 1.6.2016-1.6.2017 in 14 hospitals. We collected data on the results of LSS and follow up of cases with suspected LS.

RESULTS

In 183 out of 204 tumours (90%) LSS was performed. In 41 cases (22%) MMR protein expression was lost, in 25 cases due to hypermethylation of the MLH1 promotor. One patient was known with a pathogenic MLH1 variant. The option of genetic counselling was discussed with 12 of the 15 remaining patients, of whom three declined. After counselling by the genetic counsellor nine patients underwent germline testing. In two no pathogenic germline variant was detected, two were diagnosed with a pathogenic PMS2 variant, and five with a pathogenic MSH6 variant, in concordance with the IHC profiles.

CONCLUSION

Coverage of LSS was high (90%), though referral for genetic counselling could be improved. Gynaecologists ought to be aware of the benefits and possible drawbacks of knowing mutational status, and require training in discussing this with their patients.

Risk factors for cancer-related distress in colorectal cancer survivors: one year post surgery

PURPOSES

Cancer-related distress is known to persist long after completion of treatment. Factors related to distress are largely unexplored in colorectal cancer (CRC) survivors. We examined changes over time and risk factors for distress in CRC patients over the first year after surgery.

METHODS

We included 212 CRC patients with data at 6 and 12 months post-surgery from the ColoCare Study in Heidelberg, Germany. Sociodemographic and lifestyle factors, social support, and health-related quality of life (HrQOL) prior to surgery were evaluated as predictors of cancer-related distress. Distress was measured with the Cancer and Treatment Distress instrument (CTXD). Linear regression analyses examined associations between risk factors and distress.

RESULTS

Distress subscale scores varied significantly over time: health burden subscale score increased (P < .001), while finances (P = .004), medical demands (P < .001), and identity (P < .001) subscale scores decreased over time. Uncertainty and family strain subscale scores did not change. Younger age, lower income, advanced tumor stage, poorer social support, and poorer baseline HrQOL predicted higher level distress at 6 and 12 months.

CONCLUSION

Cancer-related distress continues unresolved after surgery. Although some risk factors are difficult to alter, those at highest risk can be identified earlier for possible preventive strategies.

IMPLICATIONS FOR CANCER SURVIVORS

Screening for risk factors pre-surgery would allow for targeted interventions including strategies to improve resources for those with low support, thereby reducing long-term distress in CRC survivors.

Is there association between stress and periodontitis?

OBJECTIVE

This study estimated the association between stress and periodontitis.

MATERIALS AND METHODS

A cross-sectional study was conducted with a sample of 621 individuals. Information about individuals was obtained through a questionnaire. Stress was evaluated using the Perceived Stress Scale. The diagnosis of periodontitis was based on a complete periodontal examination including clinical attachment level, probing depth, and bleeding on probing. Prevalence ratios (PR), crude and adjusted, and their respective 95% confidence intervals (95%CI) were estimated by Poisson regression analysis.

RESULTS

In the final sample, 48.47% (301) of the individuals were classified as having stress, of which, 23.92% (72) had the diagnosis of periodontitis. Association measurements between stress and probing depth ≥ 4 mm (PR_adjusted = 1.28, 95%CI [1.04 to 1.58]), stress and clinical attachment level ≥ 5 mm (PR_adjusted = 1.15, 95%CI [1.01 to 1.31]), and stress and periodontitis (PR_adjusted = 1.36, 95%CI [1.01 to 1.83]) showed that the frequency of these outcomes among those exposed to stress was 15-36% higher than those without the condition of stress, after adjustment for age, sex, schooling level, current smoking habit, pulmonary disease, and body mass index.

CONCLUSIONS

The findings showed positive association between exposure to stress and the presence of periodontitis, reaffirming the need to prevent and control stress.

CLINICAL RELEVANCE

Although there are limitations in this study, the results showed that an association exists between stress and periodontitis, signaling the necessity of a multidisciplinary attention when considering the psychological status in the management of oral and general health conditions of the individual.

Next-Generation Service Delivery: A Scoping Review of Patient Outcomes Associated with Alternative Models of Genetic Counseling and Genetic Testing for Hereditary Cancer

The combination of increased referral for genetic testing and the current shortage of genetic counselors has necessitated the development and implementation of alternative models of genetic counseling and testing for hereditary cancer assessment. The purpose of this scoping review is to provide an overview of the patient outcomes that are associated with alternative models of genetic testing and genetic counseling for hereditary cancer, including germline-only and tumor testing models. Seven databases were searched, selecting studies that were: (1) full-text articles published ≥2007 or conference abstracts published ≥2015, and (2) assessing patient outcomes of an alternative model of genetic counseling or testing. A total of 79 publications were included for review and synthesis. Data-charting was completed using a data-charting form that was developed by the study team for this review. Seven alternative models were identified, including four models that involved a genetic counselor: telephone, telegenic, group, and embedded genetic counseling models; and three models that did not: mainstreaming, direct, and tumor-first genetic testing models. Overall, these models may be an acceptable alternative to traditional models on knowledge, patient satisfaction, psychosocial measures, and the uptake of genetic testing; however, particular populations may be better served by traditional in-person genetic counseling. As precision medicine initiatives continue to advance, institutions should consider the implementation of new models of genetic service delivery, utilizing a model that will best serve the needs of their unique patient populations.

Functional impairments, fatigue and quality of life in RYR1-related myopathies: A questionnaire study

Mutations in RYR1 are a common genetic cause of non-dystrophic neuromuscular disorders. To obtain baseline data concerning the prevalence of fatigue, the psychological disease burden and quality of life associated with these common conditions, we performed a questionnaire study. Seventy-two patients were included in this study, 33 with a congenital myopathy and 39 with malignant hyperthermia or exertional rhabdomyolysis. Our results showed that patients with RYR1-related myopathies have more functional impairments and significant chronic fatigue compared to healthy controls, with almost half of patients being severely fatigued. Whilst fatigue, pain and associated physical and social difficulties were more pronounced in those with permanent phenotypes, individuals with intermittent phenotypes also scored higher in all relevant categories compared to healthy controls. These findings indicate that RYR1-related myopathies, despite being often considered relatively mild conditions, are nevertheless associated with severe fatigue and functional limitations, resulting in substantial loss of quality of life. Moreover, milder but in essence similar findings in patients with RYR1-related malignant hyperthermia and rhabdomyolysis suggest that those phenotypes are not truly episodic but in fact associated with a substantial permanent disease burden. These preliminary data should help to design more comprehensive quality of life studies to inform standards of care.

Diferencias de género en la percepción de estrés y estrategias de afrontamiento en pacientes con cáncer colorrectal que reciben quimioterapia

Objetivo: verificar si existen diferencias de género en la percepción de estrés y estrategias de afrontamiento; identificar las estrategias de afrontamiento y las variables clínicas y sociodemográficas que influyen sobre el estrés de pacientes con cáncer colorrectal en quimioterapia. Materiales y métodos: estudio transversal con abordaje cuantitativo. Conformaron la muestra 100 pacientes, 47 mujeres y 53 hombres, de la unidad ambulatoria de quimioterapia del AC Camargo Cancer Center, Brasil. Se utilizó la Escala de Estrés Percibido (PSS-10) e Inventario de Estrategias de Coping. El análisis estadístico fue mediante el test-t, correlación de Pearson y regresión linear con 95 % de intervalo de confianza. Resultados: Las mujeres tuvieron más altos niveles de estrés (p = 0,029), y no hubo diferencia de género en las estrategias de afrontamiento. Adicionalmente, identificamos influencia positiva al estrés percibido en pacientes comprometidos con otras enfermedades (β = 3,50, p = 0,00), género femenino (β = 3,15, p = 0,04), viudos (β = 9,19, p = 0,00), tratamiento con fluorouracil (β = 6,36, p = 0,00), que usan estrategias de dominio del afrontamiento (β = 0,70, p = 0,00), aceptación de responsabilidad (β = 0,45, p = 0,01) y estadio del tumor III (β = 4,03, p = 0,05). Conclusiones: el equipo de enfermería oncológica, por estar en estrecho y prolongado contacto con los pacientes, debe considerar el género y las características clínicas y sociodemográficas de cada paciente durante su cuidado.

Burden of spousal caregivers of stage II and III esophageal cancer survivors 3 years after treatment with curative intent

OBJECTIVES

The aim of this study is to examine caregiver burden of spousal caregivers of patients with esophageal cancer after curative treatment with neoadjuvant chemoradiation followed by resection and to assess factors associated with caregiver burden.

METHODS

In this exploratory, cross-sectional study, spousal caregivers and patients were eligible if the caregiver was the patient's spouse and the patient had been treated with chemoradiation followed by surgery after esophageal carcinoma diagnosis. Forty-seven couples were included. Spousal caregivers completed a questionnaire, examining caregivers' burden (Self-Perceived Pressure from Informal Care (SPPIC, Dutch)), caregiver unmet needs (SCNS-P&S), anxiety and depression (Hospital Anxiety and Depression Scale (HADS)), and marital satisfaction (Maudsley Marital Questionnaire (MMQ)). Patients completed the latter two questionnaires and a cancer specific quality of life questionnaire (EORTC-QLQ C30 and OES18 (oesophageal module). Logistic regression analysis was performed to identify correlates for caregiver burden.

RESULTS

The median time after esophagectomy was 38 months. Thirty-four percent of the spousal caregivers reported moderate or high burden. Spousal caregivers most frequently reported unmet needs were managing concerns about the cancer coming back (43%), dealing with others not acknowledging the impact on your life of caring for a person with cancer (38%), and balancing the needs of the person with cancer and one's own needs. A comparable proportion of spousal caregivers and patients showed symptoms of anxiety (23 vs 17%) and depression (17 vs 17%). Spousal caregivers reported significantly more dissatisfaction than patients on the marital scale (p < 0.01). Factors independently associated with higher caregiver burden were fatigue of the patient (OR = 1.66, 95% CI 1.12-2.47) and depression of the spousal caregiver (OR = 1.44, 95% CI 1.11-1.86).

CONCLUSIONS

More than a third of the spousal caregivers of patients with esophageal cancer treated with curative intent report moderate or high burden 3 years after treatment. Fatigue of the patient and depression of the spousal caregiver are associated with caregiver burden. To improve clinical care, identification of spousal caregivers at risk for experiencing higher caregiver burden and implementation of specific interventions is needed.

Self-Reported Distress in Patients With Ovarian Cancer: Is It Related to Disease Status?

Objective

Patients with epithelial ovarian cancer have a poor prognosis and often undergo intensive treatment. These patients are therefore at risk for experiencing distress and reduced quality of life. The aim of this study was to explore the self-reported distress severity, experienced problems, and quality of life in relation to their disease status.

Methods

This cross-sectional study was conducted in 2011 at a University Medical Center. Women with ovarian cancer (n = 273), both during and after treatment, were asked by mail to fill in self-report questionnaires. Distress was measured using with the Distress Thermometer (DT), Hospital Anxiety and Depression Scale, and Impact of Event Scale. Problems and quality of life were assessed with the problem list of the DT, and European Organization for Research and Treatment of Cancer Quality of Life C-30 and OV28.

Results

The questionnaire data of 104 patients were analyzed. Screening with the DT revealed distress in 32% [mean (SD), 3.1 (2.6)]. Distress was found with the Hospital Anxiety and Depression Scale in 14% [8.6 (5.9)] and with the Impact of Event Scale in 18% of the patients [17.5 (15.5)]. No significant differences were found in distress severity and self-reported problems between patients with and without recurrence. In both groups, the problems fatigue, condition, and neuropathy were most reported. Patients with distress (DT ≥ 5) experienced significantly worse functioning, more problems, and lower quality of life than patients without distress (P< 0.01).

Conclusions

This study showed that disease status in patients with ovarian cancer seems to have no influence on distress, quality of life, and the problems encountered. However, distressed patients experienced more problems, with physical and emotional functioning, and had lower quality of life. The problems fatigue, physical condition, and neuropathy are the most prevailing.

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.

Hereditary nonpolyposis colorectal cancer

Hereditary nonpolyposis colorectal cancer (HNPCC), also known as Lynch syndrome, is a class of autosomal dominant genetic disease. Main clinical characteristics of HNPCC include early onset age, more common in the right colon, and concomitant with simultaneous or metachronous extracolonic cancers, including endometrial cancer, stomach cancer, and ovarian cancer. However, the prognosis of HNPCC is better than sporadic colorectal cancer. Screening and intervention for HNPCC among high-risk pedigree population can effectively reduce the cancer incidence and mortality. In this article we will review the pathogenesis, epidemiology, diagnosis, screening, prevention and treatment of HNPCC.

How many diseases are colorectal cancer?

The development of personalised therapy and mechanism-targeted agents in oncology mandates the identification of the patient populations most likely to benefit from therapy. This paper discusses the increasing evidence as to the heterogeneity of the group of diseases called colorectal cancer. Differences in the aetiology and epidemiology of proximal and distal cancers are reflected in different clinical behaviour, histopathology, and molecular characteristics of these tumours. This may impact response both to standard cytotoxic therapies and mechanism-targeted agents. This disease heterogeneity leads to challenges in the design of clinical trials to assess novel therapies in the treatment of "colorectal cancer."
