RESUMO

BACKGROUND: BRCA1/2 mutation status has increasing relevance for ovarian cancer treatments, making traditional coordination of genetic testing by genetic services unsustainable. Consequently alternative models of genetic testing have been developed to improve testing at the initial diagnosis for all eligible women. METHODS: A training module to enable mainstreamed genetic testing by oncology healthcare professionals was developed by genetic health professionals. Oncology healthcare professionals completed questionnaires before and 12 months post-training to assess perceived skills, competence and barriers to their coordinating genetic testing for women with high-grade non-mucinous epithelial ovarian cancer. Genetic health professionals were surveyed 12 months post-training to assess perceived barriers to implementation of mainstreaming. RESULTS: 185 oncology healthcare professionals were trained in 42 workshops at 35 Australasian hospitals. Of the 273 tests ordered by oncology healthcare professionals post-training, 241 (93.1%) met national testing guidelines. The number of tests ordered by genetic health professionals reduced significantly (z = 45.0, p = 0.008). Oncology healthcare professionals' perceived barriers to mainstreamed testing decreased from baseline to follow-up (t = 2.39, p = 0.023), particularly perceived skills, knowledge and attitudes. However, only 58% reported either 'always' or 'nearly always' having ordered BRCA testing for eligible patients at 12 months, suggesting oncology healthcare professionals' perceived barriers were not systematically addressed through training. CONCLUSIONS: Oncology healthcare professionals have demonstrated a willingness to be involved in the provision of genetic testing in a mainstreaming model. If oncology services are to hold responsibility for coordinating genetic testing, their readiness will require understanding of barriers not addressed by training alone to inform future intervention design.

RESUMO

INTRODUCTION: This nationwide study assessed the impact of Lynch syndrome-related risk management guidelines on clinicians' recommendations of risk management strategies to carriers of pathogenic variants in mismatch repair genes and the extent to which carriers took up strategies in concordance with guidelines. MATERIALS AND METHODS: Clinic files of 464 carriers (with and without colorectal cancer) were audited for carriers who received their genetic testing results in July 2008-July 2009 (i.e. before guideline release), July 2010-July 2011 and July 2012-July 2013 (both after guideline release) at 12 familial cancer clinics (FCCs) to ascertain the extent to which carriers were informed about risk management in accordance with guidelines. All carriers captured by the audit were invited to participate in interviews; 215 were interviewed to assess adherence to recommended risk management guidelines. RESULTS: The rates of documentation in clinic files increased significantly from pre- to post-guideline for only two out of eight risk management strategies. The strategies with the highest compliance of carriers post-guidelines were: uptake of one or two-yearly colonoscopy (87%), followed by hysterectomy to prevent endometrial cancer (68%), aspirin as risk-reducing medication (67%) and risk-reducing salpingo-oophorectomy (63%). Interrater reliability check for all guidelines showed excellent agreement (k statistics = 0.89). CONCLUSION: These results indicate that there is scope to further increase provision of advice at FCCs to ensure that all carriers receive recommendations about evidence-based risk management. A multi-pronged behaviour change and implementation science approach tailored to specific barriers is likely to be needed to achieve optimal clinician behaviours and outcomes for carriers.

RESUMO

It is estimated that polygenic factors can explain up to 18% of familial breast cancer. Clinical implementation of polygenic testing has begun, with several commercial laboratories now testing. Despite commercial implementation, there is little research investigating how women respond and understand polygenic risk information. This study aimed to explore women's experience receiving their personalised polygenic risk score (PRS) and compare responses of women at different levels of polygenic risk. Eligible participants were affected and unaffected women from families clinically assessed to be at high risk for breast cancer who had received their personalised PRS as part of the Variants in Practice Psychosocial Study (ViPPs). In-depth semi-structured interviews were conducted with 21 women (mean age 53.4 years) up to four weeks after receiving their PRS. Interviews were transcribed verbatim and analysed using thematic analysis. Eleven women received a PRS that was in the top quartile of PRS distribution and 10 in the lowest quartile. Women's lived experience with breast cancer informed how they responded to their PRS, constructed and made sense of breast cancer risk following receipt of their PRS, and integrated this new information into their breast cancer risk management. Regardless of polygenic risk level, all participants demonstrated broad knowledge of concepts related to polygenic information and were able to accurately describe the implications of their PRS. Receiving PRS did not appear to negatively impact women's reported distress levels. Our findings suggest polygenic breast cancer information is well received and understood by women at high-risk for breast cancer.

RESUMO

Screening for pancreatic cancer (PC) in high-risk groups aimed to detect early cancers is currently done only in the research setting, and data on psychological outcomes of screening in these populations is scarce. To determine the psychological impact of a national Australian pancreatic screening program, a prospective study was conducted using validated psychological measures: impact of events scale (IES), psychological consequences questionnaire (PCQ) and the cancer worry scale. Measures were administered at baseline, 1-month and at 1-year post-enrolment and correlations with abnormal endoscopic ultrasound (EUS) results were calculated. Over a 6-year period, 102 participants were recruited to the screening program. Thirty-nine patients (38.2%) had an abnormal endoscopic ultrasound, and two patients (2.0%) were diagnosed with PC and two with other malignancies. Those with a personal history of cancer or a positive BRCA2 mutation demonstrated significantly increased worry about developing other types of cancer at baseline (p < 0.01). Irrespective of EUS result, there was a significant decrease of total IES score at 1 year (Z = - 2.0, p = 0.041). In patients with abnormal EUS results, there was a decrease in the total IES score at 1 year (Z = - 2.5, p = 0.011). In participants deemed to be most distressed at baseline based on their negative PCQ score, there was a significant decrease of the total PCQ (Z = - 3.2, p = 0.001), emotional (Z = - 3.0, p = 0.001), social (Z = 3.0, p = 0.001) and physical (Z = - 2.8, p = 0.002) subscale at 1-year post-intervention. This study provides evidence of the long-term psychological benefits of PC screening in high-risk patients. There was no negative impact of screening in the short-term and the positive benefits appeared at 1-year post-intervention irrespective of screening result.

RESUMO

This study aimed to ascertain the systemic barriers encountered by oncology health professionals (HPs) working with patients from ethnic minorities to guide the development of a communication skills training programme. Twelve medical and five radiation oncologists and 21 oncology nurses were invited to participate in this qualitative study. Participants were interviewed individually or in a focus group about their experiences working with people from minority backgrounds. All interviews were transcribed verbatim and analysed thematically. HPs encountered language and communication barriers in their interactions with patients and their families, which were perceived to impact negatively on the quality and amount of information and support provided. There was a shortage of, and poor processes for engaging, interpreters and some HPs were concerned about the accuracy of interpretation. HPs expressed a need for training in cultural awareness and communication skills with a preference for face-to-face delivery. A lack of funding, a culture of "learning on the job", and time constraints were systemic barriers to training. Oncologists and oncology nurses encounter complex challenges in clinical interactions with minority patients and their families, including difficulties working with interpreters. Formal training programmes targeted to the development of culturally competent communication skills are required.

RESUMO

BACKGROUND: Selective estrogen receptor modulators, such as tamoxifen, reduce breast cancer risk by up to 50% in women at increased risk for breast cancer. Despite tamoxifen's well-established efficacy, many studies show that most women are not taking up tamoxifen. This systematic literature review aimed to identify the motivators and barriers to tamoxifen use 's amongst high-risk women. METHODS: Using MEDLINE, PsycINFO, and Embase plus reviewing reference lists of relevant articles published between 1995 and 2016, 31 studies (published in 35 articles) were identified, which addressed high-risk women's decisions about risk-reducing medication to prevent breast cancer and were peer-reviewed primary clinical studies. RESULTS: A range of factors were identified as motivators of, and barriers to, tamoxifen uptake including: perceived risk, breast-cancer-related anxiety, health professional recommendation, perceived drug effectiveness, concerns about side-effects, knowledge and access to information about side-effects, beliefs about the role of risk-reducing medication, provision of a biomarker, preference for other forms of breast cancer risk reduction, previous treatment experience, concerns about randomization in clinical trial protocols and finally altruism. CONCLUSIONS: Results indicate that the decision for high-risk women regarding tamoxifen use or non-use as a risk-reducing medication is not straightforward. Support of women making this decision is essential and needs to encompass the full range of factors, both informational and psychological.

RESUMO

Somatic mutations in key oncogenes in non-small cell lung cancer (NSCLC) and melanoma are important determinants of tumour sensitivity to targeted therapies. Molecular screening for these predictive biomarkers is routinely used to inform treatment decisions; however, little is known about how best to communicate testing and results to patients. This qualitative study aimed to explore advanced cancer patients' attitudes and experiences regarding somatic tumour screening to identify their information and support needs. Sixteen NSCLC and eight melanoma patients who had undergone screening participated in a semi-structured face-to-face or telephone interview exploring their understanding, views, preferences and needs regarding screening. Interviews were audiotaped, transcribed and analysed for thematic patterns. Participants expressed positive views and unequivocal acceptance of screening, and understood its role in guiding treatment selection. They preferred to receive information verbally through simple, non-technical language from their oncologist with additional take-home materials. Patients were interested in learning about their test results, but wanted discussion to be focused on practical matters relevant to treatment. While receiving their screening results was not considered burdensome, information overload and cancer-related distress were identified as barriers to test comprehension. Patients may benefit from information and decision-related tools to better understand genomic information and adequately support psychosocial outcomes.

RESUMO

Evidence suggests that a significant proportion of individuals referred to cancer genetic counselling (GC) do not attend, and thus may not be engaged in adequate cancer risk management. We aimed to review the literature to better understand barriers to accessing GC and how they may be overcome. We conducted a systematic literature search for articles examining factors influencing cancer GC uptake as well as motivators and barriers to GC attendance. Factors were categorised as sociodemographic, psychosocial or clinical. The literature search identified 1413 citations, 35 of which met the inclusion criteria. GC uptake ranged from 19% to 88%. With the exceptions of education level, socioeconomic status, cancer-specific distress, personal cancer diagnosis and actual and perceived risk of cancer, support was lacking for most sociodemographic, clinical and psychosocial factors as predictors of GC uptake. Cost and logistical barriers, emotional concerns, family concerns and low perceived personal relevance were reported as important considerations for those declining GC. We conclude that there is poor understanding of GC and a lack of decision support among those referred to GC. Research into ways of providing education and support to referred individuals will be important as the scope and availability of GC and genetic testing broaden.

RESUMO

Selection of women for treatment-focused genetic testing (TFGT) following a new diagnosis of breast cancer is changing. Increasingly a patient's age and tumour characteristics rather than only their family history are driving access to TFGT, but little is known about the impact of receiving carrier-positive results in individuals with no family history of cancer. This study assesses the role of knowledge of a family history of cancer on psychosocial adjustment to TFGT in both women with and without mutation carrier-positive results. In-depth semistructured interviews were conducted with 20 women who had undergone TFGT, and who had been purposively sampled to represent women both family history and carrier status, and subjected to a rigorous qualitative analysis. It was found that mutation carriers without a family history reported difficulties in making surgical decisions quickly, while in carriers with a family history, a decision regarding surgery, electing for bilateral mastectomy (BM), had often already been made before receipt of their result. Long-term adjustment to a mutation-positive result was hindered by a sense of isolation not only by those without a family history but also those with a family history who lacked an affected relative with whom they could identify. Women with a family history who had no mutation identified and who had not elected BM reported a lack of closure following TFGT. These findings indicate support deficits hindering adjustment to positive TFGT results for women with and without a family history, particularly in regard to immediate decision-making about risk-reducing surgery.

RESUMO

PURPOSE: Women with breast cancer, who are found to be BRCA1/2 mutation carriers, have a high risk of ovarian cancer and metachronous breast cancer. Treatment-focused genetic testing (TFGT), offered around the time of diagnosis, allows genetic test results to inform surgical treatment decisions. However, concern has been raised that offering TFGT at this time may overly increase psychological burden. This study aimed to qualitatively explore women's attitudes and experiences of TFGT. METHODS: Women who had been diagnosed with breast cancer at age 50 years or less undertook a semi-structured telephone interview (n = 26). The sample included women who had been offered TFGT, based on family history and/or other risk criteria (n = 14), and women who had been diagnosed within the past 6-12 months and had not been offered TFGT (n = 12). Interviews explored women's attitudes towards TFGT, perceived benefits and disadvantages, implications of TFGT and impact on surgical decision making. Interviews were transcribed verbatim and thematically analysed. RESULTS: Women expressed positive attitudes towards TFGT and felt it was highly relevant to their surgical decision making. They did not feel that an offer of TFGT shortly after, or at the time of diagnosis, added undue psychological burden. The majority of women interviewed felt that TFGT should be incorporated into standard clinical care. CONCLUSIONS: TFGT is viewed favourably by women newly diagnosed with breast cancer. Future randomized controlled trials are needed to examine the long-term impact of TFGT. We conclude that an offer of TFGT is not perceived as 'too much, too soon' by relevant patients.

RESUMO

BACKGROUND: Fertility is a priority for many young women with breast cancer. Women need to be informed about interventions to retain fertility before chemotherapy so as to make good quality decisions. This study aimed to prospectively evaluate the efficacy of a fertility-related decision aid (DA). METHODS: A total of 120 newly diagnosed early-stage breast cancer patients from 19 Australian oncology clinics, aged 18-40 years and desired future fertility, were assessed on decisional conflict, knowledge, decision regret, and satisfaction about fertility-related treatment decisions. These were measured at baseline, 1 and 12 months, and were examined using linear mixed effects models. RESULTS: Compared with usual care, women who received the DA had reduced decisional conflict (ß=-1.51; 95%CI: -2.54 to 0.48; P=0.004) and improved knowledge (ß=0.09; 95%CI: 0.01-0.16; P=0.02), after adjusting for education, desire for children and baseline uncertainty. The DA was associated with reduced decisional regret at 1 year (ß=-3.73; 95%CI: -7.12 to -0.35; P=0.031), after adjusting for education. Women who received the DA were more satisfied with the information received on the impact of cancer treatment on fertility (P<0.001), fertility options (P=0.005), and rated it more helpful (P=0.002), than those who received standard care. CONCLUSION: These findings support widespread use of this DA shortly after diagnosis (before chemotherapy) among younger breast cancer patients who have not completed their families.

RESUMO

OBJECTIVE: There is growing evidence that the BRCA mutation status of women newly diagnosed with ovarian cancer may be used to make treatment recommendations in the future. This qualitative study aimed to assess women's attitudes and experiences toward treatment-focused genetic testing (TFGT). METHODS: Women (N=22) with ovarian cancer who had either (i) advanced disease and had previously had TFGT (n=12) or (ii) had a recent ovarian cancer diagnosis and were asked about their hypothetical views of TFGT (n=10), were interviewed in-depth. RESULTS: This study demonstrates that patients diagnosed with ovarian cancer found the concept of TFGT acceptable with the primary motivation for genetic testing being to increase their treatment options. Women reported that there was no decision to make about TFGT, and the advantages of TFGT were perceived to outweigh the disadvantages. Many women described elements of resilience and active coping, in the context of hypothetical and actual TFGT. CONCLUSIONS: Resilience and active coping strategies are important factors that warrant investigation as potential moderators of psychological distress in future prospective studies exploring the optimal way of offering BRCA genetic testing to women newly diagnosed with ovarian cancer, and to assess the impact of TFGT upon patients' survival, psychological distress, and quality of life.

RESUMO

BACKGROUND: This study examined the prevalence and correlates of skin cancer screening behaviours among individuals at high risk of developing melanoma due to strong family history. METHODS: A total of 120 individuals with a known family-specific CDKN2A mutation (72% response rate) completed a self-report questionnaire assessing annual frequency of skin self-examination (SSE), clinical skin examination (CSE) and a variety of potential demographic, clinical and psychosocial correlates. RESULTS: In the past 12 months, 50% of participants reported engaging in SSE at least four times, and 43% of participants had undergone at least one CSE. Engagement in SSE was associated with doctor recommendation (ß=1.77, P=0.001), confidence in one's ability to perform SSE (ß=1.44, P<0.0001), positive beliefs about melanoma treatment (ß=0.77, P=0.002) and intention to perform SSE in the future (ß=1.69, P<0.0001). These variables accounted for 59% of the variance in SSE behaviour. Further, information-seeking style moderated the relationship between anxiety and SSE (ß=1.02, P=0.004). Annual uptake of CSE was associated with doctor recommendation (ß=2.21, P<0.0001) and intention to undergo CSE in the future (ß=1.19, P=0.001). CONCLUSION: In comparison with clinical guidelines, it appears that individuals at high risk of developing melanoma engage in suboptimal levels of skin surveillance. Improved doctor-patient communication, as well as psycho-education and behavioural support, may be viable means of improving early skin cancer detection behaviours in this high-risk population.

RESUMO

BACKGROUND: Use of University of Wisconsin solution has been suggested for extended organ preservation >4 hours in experimental cardiac transplantation, but few data have been reported from clinical use. This study investigated the impact of preservation with UW solution after prolonged ischemic times on myocardial damage and outcomes after heart transplantation. MATERIALS AND METHODS: Between 1994 and 2006, 34 orthotopic heart transplantations were performed at our institution with cold ischemic times of >or=300 minutes (mean, 325.1 +/- 21.3). Donor organs were perfused with and stored in 1000 mL of University of Wisconsin solution. No significant differences were observed with regard to age, gender, diagnosis, donor inotropic support, and donor-recipient weight ratio when compared with recipients undergoing an ischemic time <300 minutes. RESULTS: After a mean follow-up of 47.6 months (range, 1 day to 147.1 months), Kaplan-Meier survival analysis revealed survivals of 91.0% at 3 months, and 82.9% for the entire observation period. The time required to wean from bypass (mean, 78.1 minutes) was equal when compared with that of recipients experiencing grafts undergoing an ischemic time of <300 minutes, but there was a significantly greater average need for inotropic support over the first 48 posttransplant hours. Neither hospital stay in the ICU (mean, 13.0 days; range, 1-55 days) nor the incidence of acute graft failure or survival was different. CONCLUSION: We conclude that heart preservation with UW limited ischemic damage from prolonged storage and improved myocardial function in the early posttransplant period, thus allowing transplantation of organs with ischemic times >300 minutes.

RESUMO

PURPOSE: Despite the established importance of the role of family history in prostate cancer, relatively little research encompasses the psychosocial issues relevant to unaffected men with a family history of prostate cancer. To determine the completeness and quality of available literature on the issues faced by men with a high risk of prostate cancer, we conducted a multidisciplinary review of the literature to provide some guidance on the information that clinicians might provide to men who are concerned about family history. MATERIALS AND METHODS: A structured literature search was conducted by a multidisciplinary team of clinicians and researchers who reviewed the medical and psychosocial literature, and identified 21 relevant studies. RESULTS: Research suggests that many high risk patients are concerned about the risk of prostate cancer, and some may significantly overestimate that risk. Several studies have shown high screening rates among high risk patients and high levels of interest in genetic testing for prostate cancer risk should it become available, yet many men also report a desire for more information about their personal risk and risk management options. CONCLUSIONS: Given the lack of clear data on the efficacy of prostate cancer screening among high risk patients, clinicians could consider providing men who are concerned about family history with information on their personal risk, help them to clarify the potential benefits, limitations and harms of prostate cancer screening in their situation, and then support their choice regarding the management of prostate cancer risk.

RESUMO

Despite rapid advancements in molecular genetics research, little is known about the psychological experiences of individuals with a family history of melanoma. The present study aimed to identify factors contributing to psychological distress among affected and unaffected individuals with a strong family history of melanoma. A total of 121 adults who had recently been informed of the identification of a family-specific mutation in the CDKN2A melanoma susceptibility gene, completed a self-report questionnaire assessing cancer-specific and generalized distress, and a variety of potential predictors. Having a personal history of melanoma (OR = 3.37, p = 0.033), perceiving greater family implications of melanoma (OR = 2.52, p < 0.0001), and the tendency to monitor for threatening information (OR = 3.12, p = 0.008) were associated with melanoma-specific distress. Being childless (beta = 2.09, p = 0.007), perceiving sun exposure as an important cause of melanoma (beta = 1.15, p = 0.015), and perceiving greater family implications of melanoma (beta = 1.02, p = 0.002) were associated with greater generalized anxiety, while monitoring moderated the relationship between endorsement of a genetic model of melanoma and generalized anxiety (p = 0.005). As in other common familial cancers, distress was relatively uncommon in this familial melanoma cohort, even after notification of the presence of a family mutation. Participants do not contemplate their melanoma risk in isolation, but evaluate their risk vis-à-vis the experiences of their relatives.

RESUMO

The mammalian-target-of-rapamycin/mTOR-inhibitor sirolimus as a component of the immunosuppressive strategy after solid organ transplantation is effective at preventing allograft rejection. However, recent reports indicate that sirolimus is associated with altered sex hormone levels and impaired sperm quality parameters. Herein, we report on a case of sirolimus-associated infertility in a young male heart-lung transplant recipient and provide a detailed synopsis of potential mechanisms by which sirolimus may negatively influence spermatogenesis. Testicular immunohistochemistry, the course of sex hormone and sperm quality parameters of our patient support the hypothesis that mTOR might act as an important key regulator in the reproductive system. Fortunately, due to withdrawal of sirolimus as part of the maintenance, immunosuppression improved sperm quality and sex hormone parameters could be observed. Recently, these improvements even resulted in a spontaneous pregnancy of the patient's wife more than 1 year after the drug was withdrawn. In our view, oligospermia as a possible and at least partly reversible side-effect of mTOR inhibitors has to be taken into consideration, particularly, when administrated to young male patients.

RESUMO

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.

RESUMO

This study compared language preferences to describe a cancer-related mutation in three groups: 253 members of the general community, 20 clinicians working in cancer genetics, and 269 individuals at increased risk of carrying a cancer-related mutation (including 198 women with a strong family history of breast and/or ovarian cancer, and 71 individuals with a family history of hereditary non-polyposis colorectal cancer). In the community sample, 'faulty gene' was the preferred term to describe a cancer-related mutation, although females, those affected by cancer and those who felt cancer had a large impact on their lives were more likely to prefer the terms 'gene change' or 'altered gene'. In contrast, the clinicians' preference ratings for 'faulty gene' and 'gene change' were equal. When forced to choose between 'faulty gene' and 'altered gene', the high-risk patient group reported preferring 'faulty gene', although over 40% were happy with either term. Further research investigating individuals' understanding of the different terms that can be used to describe a cancer-related mutation, and the functional impact of these terms on patients' thoughts and feelings about their condition and on their health-related behavior after genetic counseling would be worthwhile.
