RESUMEN
BACKGROUND: The role of interpersonal relationship functioning in trauma recovery is well-established. However, much of this research has been done with cross-sectional samples, often years after trauma exposure, using self-report methodology only, and is focused on intimate relationship adjustment. METHODS: The current study investigated the longitudinal associations between interpersonal (intimate and non-intimate) relationship functioning and clinician- and self-reported posttraumatic stress disorder (PTSD) symptoms in 151 recently (within the past 6 months) traumatized individuals. Participants were assessed at four time points over 1 year. RESULTS: Approximately 53% of the sample was diagnosed with PTSD at initial assessment, with declining rates of diagnostic status over time to 16%. Latent difference score (LDS) modeling revealed nonlinear declines in both clinician-assessed and self-reported PTSD symptom severity, with faster declines in earlier periods. Likewise, LDS models revealed nonlinear declines in negative (conflict) aspects of interpersonal relationship functioning, but linear declines in positive (support, depth) aspects. The relationship between PTSD and relationship functioning differed for clinician- and self-reported PTSD. Bivariate LDS modeling revealed significant cross-lagged effects from relationship conflict to clinician-assessed PTSD, and significant cross-lagged effects from self-reported PTSD to relationship conflict over time. CONCLUSIONS: These results highlight that the variability in prior results may be related to the method of assessing PTSD symptomatology and different relational constructs. Implications for theory and early intervention are discussed.

Research has established that social factors are integral to trauma recovery. Yet, there is relatively little data on the association between social interactions from different supports and posttraumatic stress disorder (PTSD) symptoms. Moreover, few studies have measured these factors from multiple informants. This paper examined social interactions from different sources (i.e., negative and positive reactions from a chosen close other [CO], family/friends, and general non-COs) and their association with PTSD symptoms using multi-informant reports of the social constructs (i.e., from the individual exposed to trauma [TI] and their CO). Participants (N = 104 dyads) were recruited from an urban center within 6 months of the TIs' exposure to a traumatic event. TIs were assessed using the Clinician-Administered PTSD Scale. TI self-report, t(97) = 2.58, p = .012, and CO collateral report of disapproval from family/friends, t(97) = 2.14, p = .035, and TI self-report of general disapproval, t(97) = 4.91, p < .001, emerged as significant predictors of PTSD symptoms when compared with other social constructs. Interventions that target family members' and friends' reactions to trauma survivors and societal discourse around trauma and reactions to trauma survivors are recommended. Clinical interventions that buffer against TIs' experiences of disapproval and guide COs on the provision of supportive responses are discussed.

PURPOSE/OBJECTIVES: To examine the extent to which religious/spiritual coping moderates the association between stress appraisals and hope among patients with colorectal cancer. DESIGN/RESEARCH APPROACH: A longitudinal, prospective examination of hope, stress appraisals of cancer, and religious/spiritual coping through self-report questionnaires at baseline, 6-months, and 12-months post-surgery. SAMPLE/PARTICIPANTS: One hundred thirty-nine newly diagnosed patients with colorectal cancer recruited from tertiary medical centers. FINDINGS: Challenge and threat appraisals predicted hope. Only the relationship between hope and challenge appraisals was significantly moderated by coping through religion/spirituality, such that those who were both low on challenge and low in religious/spiritual coping reported the lowest hope. CONCLUSIONS/INTERPRETATION: Hope is predicted by how people appraise their cancer. Hope was lowest among participants who reported both low challenge appraisals and religious/spiritual coping. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS: Understanding how patients appraise their cancer and use religion/spirituality to cope may help providers understand which patients are at risk for low hope.

OBJECTIVE: There is limited research examining how change in cancer-related fatigue (CRF) over time predicts change in health-related quality of life (HRQOL), and no studies have examined this relationship in ovarian cancer patients, specifically. The purpose of this study was to explore the prevalence and trajectory of CRF over time and examine how change in CRF over time predicts change in HRQOL in ovarian cancer patients. METHODS: Ovarian cancer patients (N = 202) were recruited from Princess Margaret Cancer Centre in Toronto, Canada. Consenting participants completed measures at baseline (beginning of study) and again three months later. Data were analyzed using a longitudinal multilevel mixed model design. RESULTS: Four groups of CRF trajectories emerged. Fifty-four percent reported CRF as always present, 16% reported CRF subsided, 21% reported CRF developed, and 9% reported CRF as never present. As CRF developed, functional and physical wellbeing decreased. As CRF subsided, functional, physical, and emotional wellbeing improved. CRF trajectory was not associated with change in social wellbeing over time. CONCLUSIONS: Our findings suggest CRF negatively impacts all domains of HRQOL except for social wellbeing in ovarian cancer patients. Among patients who reported that CRF improved over time, all HRQOL domains impacted by CRF showed recovery to normal endorsement rates. Among patients who reported development of CRF, impacted HRQOL domains significantly declined over time. Implications from this research indicate that fatigue management should be prioritized during and after cancer treatment to ensure optimal physical, functional, and emotional wellbeing.

OBJECTIVES: While ovarian cancer is the third most common Lynch syndrome-associated cancer in women, there is no established screening strategy to identify Lynch syndrome in this population. The objective of this study was to assess whether the 4-item brief Family History Questionnaire can be used as a screening tool to identify women with ovarian cancer at risk of Lynch syndrome. METHODS: In this prospective cohort study, participants with newly diagnosed non-serous, non-mucinous ovarian cancer completed the brief Family History Questionnaire, extended Family History Questionnaire, and had tumors assessed with immunohistochemistry for mismatch repair proteins, MLH1 methylation, and microsatellite instability testing. All underwent universal germline testing for Lynch syndrome. Performance characteristics were compared between the brief Family History Questionnaire, extended Family History Questionnaire, immunohistochemistry±MLH1 methylation, and microsatellite instability testing. RESULTS: Of 215 participants, 169 (79%) were evaluable with both the brief Family History Questionnaire and germline mutation status; 12 of these 169 were confirmed to have Lynch syndrome (7%). 10 of 12 patients (83%) with Lynch syndrome were correctly identified by the brief Family History Questionnaire, compared with 6 of 11 (55%) by the extended Family History Questionnaire, 11 of 13 (85%) by immunohistochemistry±MLH1 methylation, and 9 of 11 (82%) by microsatellite instability testing. The sensitivity, specificity, positive predictive values, and negative predictive values of the brief Family History Questionnaire were 83%, 65%, 15%, and 98%, respectively. A combined approach with immunohistochemistry and the brief Family History Questionnaire correctly identified all 12 patients with Lynch syndrome. The brief Family History Questionnaire was more sensitive than the extended Family History Questionnaire and took <10 min for each patient to complete. CONCLUSIONS: The brief Family History Questionnaire alone or combined with immunohistochemistry may serve as an adequate screening strategy, especially in centers without access to universal tumor testing.

BACKGROUND: Despite recommendations for reflex immunohistochemistry (IHC) for mismatch repair (MMR) proteins to identify Lynch syndrome (LS), the uptake of genetic assessment by those who meet referral criteria is low. The authors implemented a comprehensive genetic navigation program to increase the uptake of genetic testing for LS in patients with endometrial cancer (EC) or nonserous/nonmucinous ovarian cancer (OC). METHODS: Participants with newly diagnosed EC or OC were prospectively recruited from 3 cancer centers in Ontario, Canada. Family history questionnaires were used to assess LS-specific family history. Reflex IHC for MMR proteins was performed with the inclusion of clinical directives in pathology reports. A trained genetic navigator initiated a genetic referral on behalf of the treating physician and facilitated genetic referrals to the closest genetics center. RESULTS: A total of 841 participants (642 with EC, 172 with OC, and 27 with synchronous EC/OC) consented to the study; 194 (23%) were MMR-deficient by IHC. Overall, 170 women (20%) were eligible for a genetic assessment for LS: 35 on the basis of their family history alone, 24 on the basis of their family history and IHC, 82 on the basis of IHC alone, and 29 on the basis of clinical discretion. After adjustments for participants who died (n = 6), 149 of 164 patients (91%) completed a genetic assessment, and 111 were offered and completed genetic testing. Thirty-four women (4.0% of the total cohort and 30.6% of those with genetic testing) were diagnosed with LS: 5 with mutL homolog 1 (MLH1), 9 with mutS homolog 2 (MSH2), 15 with mutS homolog 6 (MSH6), and 5 with PMS2. CONCLUSIONS: The introduction of a navigated genetic program resulted in a high rate of genetic assessment (>90%) in patients with gynecologic cancer at risk for LS.

OBJECTIVES: Findings on impact of mismatch repair deficiency (MMRd) on patient outcomes in endometrial cancer (EC) have been inconsistent to date. The objective of this study was to compare the oncologic outcomes and recurrence patterns between MMRd and MMR-intact (MMRi) endometrioid EC (EEC). METHODS: Between 2015 and 2018, we prospectively recruited 492 EEC cases from three cancer centers in Ontario, Canada. Tumors were reflexively assessed for MMR protein expression by immunohistochemistry (IHC). Clinicopathological, survival and recurrence patterns were compared between MMRd and MMRi cases. RESULTS: Of 492 EEC, 348 were MMRi (71%) and 144 were MMRd (29%) with median follow-up of 16.8 months (0-69.6). MMRd tumors tended to be grade 2 or 3 (56% vs. 29%, p < 0.001), with propensity for lymphovascular space invasion (28% vs. 18%, p = 0.024), lymph node involvement (7% vs. 5%, p < 0.001) and received more adjuvant treatment (46% vs. 33%, p = 0.027). This group also had significantly lower 3-year recurrence-free survival (78% vs. 90%, p = 0.014) although there was no difference in OS (p = 0.603). MMRd cases were more likely to recur in retroperitoneal lymph nodes (p = 0.045). Upon subgroup analysis, MLH1 methylated tumors had the worst prognostic features and survival outcomes. CONCLUSIONS: MLH1 methylated EECs exhibit more aggressive features compared to other MMRd and MMRi EECs. This may indicate an inherent difference in tumor biology, suggesting the importance of individualized management based on EC molecular phenotype.

BACKGROUND: For women with ovarian cancer (OC), the optimal screening strategy to identify Lynch syndrome (LS) has not been determined. In the current study, the authors compared the performance characteristics of various strategies combining mismatch repair (MMR) immunohistochemistry (IHC), microsatellite instability testing (MSI), and family history for the detection of LS. METHODS: Women with nonserous and/or nonmucinous ovarian cancer were recruited prospectively from 3 cancer centers in Ontario, Canada. All underwent germline testing for LS and completed a family history assessment. Tumors were assessed using MMR IHC and MSI. The sensitivity, specificity, and positive and negative predictive values of screening strategies were compared with the gold standard of a germline result. RESULTS: Of 215 women, germline data were available for 189 (88%); 13 women (7%) had pathogenic germline variants with 7 women with mutS homolog 6 (MSH6); 3 women with mutL homolog 1 (MLH1); 2 women with PMS1 homolog 2, mismatch repair system component (PMS2); and 1 woman with mutS homolog 2 (MSH2). A total of 28 women had MMR-deficient tumors (13%); of these, 11 had pathogenic variants (39%). Sequential IHC (with MLH1 promoter methylation analysis on MLH1-deficient tumors) followed by MSI for nonmethylated and/or MMR-intact patients was the most sensitive (92.3%; 95% confidence interval, 64%-99.8%) and specific (97.7%; 95% confidence interval, 94.2%-99.4%) approach, missing 1 case of LS. IHC with MLH1 promoter methylation analysis missed 2 patients of LS. Family history was found to have the lowest sensitivity at 55%. CONCLUSIONS: Sequential IHC (with MLH1 promoter methylation analysis) followed by MSI was found to be most sensitive. However, IHC with MLH1 promoter methylation analysis also performed well and is likely more cost-effective and efficient in the clinical setting. The pretest probability of LS is high in patients with MMR deficiency and warrants universal screening for LS.

OBJECTIVES: For synchronous endometrial and ovarian cancers, most centers rely on mismatch repair testing of the endometrial cancer to identify Lynch syndrome, and neglect the ovarian tumor site completely. We examined the mismatch repair immunohistochemistry and microsatellite instability results from the endometrium and ovary to assess discordance between the tumor sites and between tests. METHODS: 30 women with newly diagnosed synchronous endometrial and ovarian cancer were prospectively recruited from three cancer centers in Ontario, Canada. Both tumor sites were assessed for mismatch repair deficiency by immunohistochemistry and microsatellite instability test; discordance in results between tumor sites and discordance between test results at each site was examined. Cases with discordant results had tumors sequenced with a targeted panel in order to reconcile the findings. All women underwent mismatch repair gene germline testing. RESULTS: Of 30 patients, 11 (37%) were mismatch repair deficient or microsatellite instable at either tumor site, with 5 (17%) testing positive for Lynch syndrome. Mismatch repair immunohistochemistry expression was discordant between endometrial and ovarian tumor sites in 2 of 27 patients (7%) while microsatellite instability results were discordant in 2 of 25 patients (8%). Relying on immunohistochemistry or microsatellite instability alone on the endometrial tumor would have missed one and three cases of Lynch syndrome, respectively. One patient with Lynch syndrome with a PMS2 pathogenic variant was not detected by either immunohistochemistry or microsatellite instability testing. The rate of discordance between immunohistochemistry and microsatellite instability test was 3.8% in the ovary and 12% in the endometrium. CONCLUSIONS: There was discordance in immunohistochemistry and microsatellite instability results between tumor sites and between tests within each site. Endometrial tumor testing with mismatch repair immunohistochemistry performed well, but missed one case of Lynch syndrome. Given the high incidence of Lynch syndrome (17%), consideration may be given to germline testing in all patients with synchronous endometrial and ovarian cancers.

Cancer is an interpersonal stressor affecting both patient and spouse. To examine the pathways that insecure adult attachment can impact health outcomes by way of dyadic processes, this cross-sectional study used the actor-partner interdependence mediation model to examine whether common dyadic coping (CDC) mediated the associations between attachment and quality of life (QOL). Couples (N = 106) facing ovarian cancer were recruited from a comprehensive cancer center and completed self-report questionnaires. Results indicated that worse social and functional QOL were associated with both one's own and one's partner's greater insecure attachment, by way of one's own use of less CDC. Unexpectedly, greater CDC reported by one's partner was associated with one's own lower functional QOL. Although CDC has beneficial effects on QOL, CDC may also be experienced as draining. Effects of adult attachment on dyadic coping are a significant contributor to subjective health outcomes among couples facing ovarian cancer.

OBJECTIVE AND BACKGROUND: Fatigue and insomnia are common debilitating symptoms associated with multiple sclerosis (MS). Negative subjective appraisals of symptoms may influence both insomnia and fatigue severity, but this relationship has not been examined among those with MS. The relationship between insomnia symptoms and both physical and cognitive fatigue were examined. Health-related self-efficacy, fatigue catastrophization, and rumination were examined as potential mediators of the relationship between insomnia symptoms and fatigue. PARTICIPANTS: Participants diagnosed with MS (N = 115) were recruited from hospital and community settings in a large metropolitan city. METHODS: Participants completed self-report questionnaires, including: Modified Fatigue Impact, Insomnia Severity Index, MS Quality of Life Questionnaire-54, Fatigue Catastrophizing Scale, Multidimensional Health Locus of Control Scale, and the Rumination-Reflection Questionnaire. Two multiple mediation analyses were performed using bootstrapping techniques, examining the cognitive and physical domains of fatigue as separate outcomes. RESULTS AND CONCLUSIONS: Mediation analyses revealed a significant association between insomnia symptom severity and the cognitive and physical domains of fatigue. Fatigue catastrophizing was the only significant mediator, accounting for 25% of the variance in the relationship between insomnia symptoms and the cognitive fatigue. However, fatigue catastrophizing did not significantly mediate the relationship between insomnia symptoms and physical fatigue, indicating physical and cognitive fatigue may reflect distinct processes in fatigue expression in those with MS.

This study examined the differences in perceptions of one's health and one's child's health between parents with Lynch syndrome (LS) characterized with high versus low health anxiety. Twenty-one parents completed semistructured telephone interviews about their perceptions of their own health and the health of their children. Qualitative content analysis using a template coding approach examined the differences between parents with high and low health anxiety. Findings revealed that the most prevalent difference emerged on perceptions of personal health, showing individuals with high health anxiety reported more extreme worries, were more hypervigilant about physical symptoms, experienced the emotional and psychological consequences of LS as more negative and severe, and engaged in more dysfunctional coping strategies than those with low health anxiety. Unexpectedly, with regards to perceptions of their children, parents in the high and low health anxiety groups exhibited similar worries. However, high health anxiety parents reported using dysfunctional coping about their children's health more frequently than those with low health anxiety. The findings suggest that health anxiety is of clinical significance for individuals with LS. Accurately identifying and treating health anxiety among this population may be one avenue to reduce the distress experienced by LS carriers.

BACKGROUND: Lynch syndrome, a hereditary cancer syndrome, predisposes women to colorectal, endometrial, and ovarian cancer. Current guidelines recommend that women with Lynch syndrome undergo risk-reducing gynecological surgery to reduce their chances of developing endometrial or ovarian cancer. Little is known about how women with Lynch syndrome perceive gynecological cancer screening, or the psychosocial factors associated with screening attitudes and behaviour. METHODS: This study used a cross-sectional, quantitative design. Using self-report questionnaire data from a sample of women with Lynch syndrome (N = 50) who had not undergone risk-reducing surgery, the current study sought to: 1) describe the gynecological cancer screening behaviours of women with Lynch syndrome, as well participant-reported sources of information about Lynch syndrome; 2) examine the extent to which women believe gynecological cancer screening is effective and provides them with reassurance and; 3) assess to what extent relationships with one's family physician were associated with gynecological cancer screening, perceptions about screening, and health self-efficacy. Data were analyzed using descriptive statistics and Spearman rank-ordered correlations. RESULTS: Data analyses showed that transvaginal ultrasound was the most common screening behaviour (57%) followed by pelvic ultrasound (47%). Only 22% of participants underwent endometrial biopsy. Patient-physician relationships were related to greater health self-efficacy to manage Lynch syndrome and greater perceived effectiveness of gynecological screening. However, health self-efficacy and better patient-physician relationships were not associated with increased engagement in gynecological cancer screening. CONCLUSIONS: The data suggest that feeling efficacious about managing one's Lynch syndrome and screening is related to positive interactions and communication with one's family physician. While this is encouraging, future research should examine educating both family physicians and patients about current guidelines for Lynch syndrome gynecological screening recommendations.
RESUMEN
BACKGROUND: First-degree relatives (FDRs) of probands with colorectal cancer (CRC) may be at increased risk of CRC and require colonoscopy. Proband disclosure about this risk and need for colonoscopy is essential for FDRs to take appropriate action. Low colonoscopy rates are reported among FDRs and little is known about the proband disclosure process. A better understanding of the barriers surrounding colonoscopy and disclosure is needed. METHODS: CRC probands (n = 16) and FDRs (n = 9), recruited from a Canadian CRC Consortium, completed interviews to determine barriers to disclosure and colonoscopy, respectively. Interviews were analyzed using thematic analysis and participants' motivation to disclose to FDRs or undertake colonoscopy was categorized into Stages of Change (i.e., Precontemplation, Contemplation, Preparation, Action, or Maintenance) using the transtheoretical model. RESULTS: 25% of probands had not disclosed to any first-degree kin and were categorized in the Precontemplation or Contemplation Stage of Change. Barriers to disclosure included lack of information, negative expectations about familial reaction, assuming FDRs were aware of risk or already being screened, dysfunctional family dynamics, and cultural barriers. 75% of FDRs were categorized in the Precontemplation or Contemplation Stage of Change. Barriers included negative perceptions about colonoscopy, health-care provider related factors, practical concerns, and lack of information about CRC, risk, and colonoscopy. CONCLUSIONS: In the absence of barriers such as cost and accessibility, this Canadian sample still reported several challenges to disclosure and colonoscopy adherence. Future research should explore interventions such as motivational interviewing to improve proband disclosure and to increase FDR adherence to colonoscopy.
RESUMEN
BACKGROUND: Data are lacking regarding physical functioning, psychological well-being, and quality of life among colorectal cancer survivors >10 years postdiagnosis. OBJECTIVE: The purpose of this study was to examine self-reported physical functioning, quality of life, and psychological well-being in long-term colorectal cancer survivors compared with age- and sex-matched unaffected control subjects. DESIGN: Participants completed a cross-sectional survey. SETTINGS: The colorectal cancer survivors and unaffected control subjects were recruited from the Ontario Familial Colorectal Cancer Registry. PATIENTS: A population-based sample of colorectal cancer survivors (N = 296) and their age- and sex-matched unaffected control subjects (N = 255) were included. Survivors were, on average, 15 years postdiagnosis. MAIN OUTCOME MEASURES: Quality of life was measured with the Functional Assessment of Cancer Therapy-General scale, bowel dysfunction with the Memorial Sloan-Kettering Cancer Center scale, urinary dysfunction with the International Consultation on Incontinence Questionnaire-Short Form, fatigue with the Functional Assessment of Chronic Illness Therapy-Fatigue scale, and depression with the Center for Epidemiologic Studies-Depression scale. RESULTS: In linear mixed-model analyses adjusting for income, education, race, and comorbid medical conditions, survivors reported good emotional, functional, physical, and overall quality of life, comparable to control subjects. Fatigue and urinary functioning did not differ significantly between survivors and control subjects. Survivors reported significantly higher social quality of life and lower depression compared with unaffected control subjects. The only area where survivors reported significantly worse deficits was in bowel dysfunction, but the magnitude of differences was relatively small. LIMITATIONS: Generalizability is limited by moderately low participation rates. Findings are likely biased toward healthy participants. No baseline assessment was available to examine change in outcomes over time. CONCLUSIONS: Long-term colorectal cancer survivors appear to have comparable quality of life and, in some areas, better well-being than their unaffected peers. Bowel dysfunction may continue to be an ongoing issue even 15 years after colorectal cancer diagnosis. Overall quality of life can be expected to be good in this group of older survivors.

OBJECTIVE: Previous research has suggested that gay men facing prostate cancer may be particularly vulnerable to poor illness adjustment. Moreover, although attachment and greater disclosure of sexual orientation have been associated with health outcomes, their associations in this population have been largely unexamined. The purpose of the present study was to investigate whether greater outness about one's sexual orientation significantly mediated the associations between anxious and avoidant attachment and illness intrusiveness among gay men with prostate cancer. METHODS: Ninety-two gay and bisexual men who had received a diagnosis of prostate cancer in the past 4 years were recruited for the present study. Self-report questionnaires assessed demographic and medical variables, attachment, outness level and comfort, and illness intrusiveness. Bootstrapping procedures were used to assess for mediation. RESULTS: Results suggested significant associations between anxious attachment, outness comfort, and illness intrusiveness. Less comfort with outness significantly mediated the association between greater anxious attachment and more illness intrusiveness. Avoidant attachment was not significantly associated with illness intrusiveness. CONCLUSIONS: Findings support the mediating role of the subjective experience of being an out gay man in the association between anxious attachment and illness intrusiveness. These results suggest that facilitating greater comfort with outness would be beneficial for illness adjustment among gay men with prostate cancer whom have more anxious attachment styles.

This study investigated the extent to which intolerance of uncertainty was associated with cancer worry interference, anxiety and depression among women with Lynch syndrome (LS), and whether having greater trust in one's physician moderated those relationships. Women with confirmed LS (N = 128) were recruited from a high-risk of cancer registry and completed a one-time self-report questionnaire. Women who reported greater intolerance of uncertainty and more trust in their physician reported less cancer worry interference compared to women who had greater intolerance of uncertainty and less trust in their physician, who reported the highest worry interference, b = -1.39, t(99) = -2.27, p = .03. No moderation effect of trust in physician was found for anxiety or depression. Trust in one's physician buffered the impact of high intolerance of uncertainty on cancer worry interference, underscoring the need for supportive provider-patient relationships, particularly for LS patients.

Currently, there is a lack of evidence evaluating the psychological impact of cancer-related risk perception and worry in individuals at high risk for gastric cancer. We examined the relationships between perceived risk, cancer worry and screening behaviors among first-degree relatives (FDRs) of patients with familial gastric cancer. FDRs of patients diagnosed with familial gastric cancer with a non-informative genetic analysis were identified and contacted. Participants completed a telephone interview that assessed socio-demographic information, cancer risk perception, cancer worry, impact of worry on daily functioning, and screening behaviors. Twenty-five FDRs completed the telephone interview. Participants reported high levels of comparative and absolute cancer risk perception, with an average perceived lifetime risk of 54 %. On the other hand, cancer-related worry scores were low, with a significant minority (12 %) experiencing high levels of worry. Study participants exhibited high levels of confidence (median = 70 %) in the effectiveness of screening at detecting a curable cancer. Participants that had undergone screening in the past showed significantly lower levels of cancer-related worry compared to those that had never undergone screening. In conclusion, individuals at high-risk for gastric cancer perceived a very high personal risk of cancer, but reported low levels of cancer worry. This paradoxical result may be attributed to participants' high levels of confidence in the effectiveness of screening. These findings highlight the importance for clinicians to discuss realistic risk appraisals and expectations towards screening with unaffected members of families at risk for gastric cancer, in an effort to help mitigate anxiety and help with coping.

OBJECTIVE: Limited research has investigated the psychosocial processes that underpin the effect of physical symptoms on fear of cancer recurrence. Additionally, despite evidence of increased vulnerability of marginalized populations to negative outcomes, few studies have examined the unique experience of gay men coping with the cancer process. The goals of this study were to determine whether disease-related self-efficacy and satisfaction with medical care mediated the relationship between greater physical symptoms and worse fear of recurrence among gay or bisexual prostate cancer survivors. METHODS: Participants were composed of 92 self-identified gay or bisexual men, who had received a diagnosis of prostate cancer in the past 4 years. Participants provided demographic information and completed self-report questionnaires that assessed symptom function, self-efficacy for prostate cancer symptoms, satisfaction with healthcare, and fear of recurrence. Bootstrapping procedures were used to assess for significant mediation. RESULTS: Results suggested significant mediation of the relationship between each of bowel, hormonal, and sexual function with fear of recurrence by self-efficacy and satisfaction with healthcare. Mediation was not significantly supported for the association between urinary function and fear of recurrence. CONCLUSIONS: Findings support the explanatory effects of self-efficacy for symptom management and satisfaction with healthcare on the relationship between symptom function and fear of recurrence. These results indicate that psychological processes, specifically psychological factors that hold particular relevance to gay or bisexual men, reflect a potential avenue for intervention to decrease fear of cancer recurrence.

INTRODUCTION: Gay men with prostate cancer (GMPCa) may have differential health-related quality of life (HRQOL) and sexual health outcomes than heterosexual men with prostate cancer (PCa), but existing information is based on clinical experience and small studies. AIMS: Our goals were to: (i) describe HRQOL and examine changes in sexual functioning and bother; (ii) explore the psychosocial aspects of sexual health after PCa; and (iii) examine whether there were significant differences on HRQOL and sexual behavior between GMPCa and published norms. METHODS: A convenience sample of GMPCa completed validated disease-specific and general measures of HRQOL, ejaculatory function and bother, fear of cancer recurrence, and satisfaction with prostate cancer care. Measures of self-efficacy for PCa management, illness intrusiveness, and disclosure of sexual orientation were also completed. Where possible, scores were compared against published norms. MAIN OUTCOME MEASURES: Main outcome measures were self-reported sexual functioning and bother on the Expanded Prostate Cancer Index. RESULTS: Compared with norms, GMPCa reported significantly worse functioning and more severe bother scores on urinary, bowel, hormonal symptom scales (Ps < 0.015-0.0001), worse mental health functioning (P < 0.0001), greater fear of cancer recurrence (P < 0.0001), and were more dissatisfied with their PCa medical care. However, GMPCa reported better sexual functioning scores (P < 0.002) compared with norms. Many of the observed differences met criteria for clinical significance. Physical functioning HRQOL and sexual bother scores were similar to that of published samples. GMPCa tended to be more "out" about their sexual orientation than other samples of gay men. CONCLUSIONS: GMPCa reported substantial changes in sexual functioning after PCa treatment. They also reported significantly worse disease-specific and general HRQOL, fear of recurrence, and were less satisfied with their medical care than other published PCa samples. Sexual health providers must have an awareness of the unique functional and HRQOL differences between gay and heterosexual men with PCa.
