RESUMO

OBJECTIVE: Clinical fear of cancer recurrence (FCR) was recently defined by a group of experts during a Delphi study. Five criteria were agreed upon, namely: (a) high levels of preoccupation, (b) high levels of worry, (c) that are persistent, (d) hypervigilance and hypersensitivity to physical sensations that e) may result in functional impairment. No existing instruments comprehensively capture all these criteria for clinical FCR. METHODS: To remedy this gap, a set of three patient-reported outcome instruments including a one-item screener, self-report questionnaire, and semi-structured clinical interview, named the Ottawa Clinical Fear of Recurrence instruments, were developed. To do so, the research team first conducted a literature review of potential items. Additional FCR experts discussed the content of the screener and interview. The self-report's items were assessed for content validity by the same expert panel using Likert ratings and the Content Validity Index to narrow down the number of items. The three instruments were piloted with a group of cancer survivors to assess face validity following the European Organization for Research and Treatment of Cancer recommendations. RESULTS: The literature review and content validity assessment led to a final draft pre-pilot of 23 potential items for the self-report questionnaire. The instruments were piloted. Pilot study participants suggested changing wording and response options (particularly for the self-report) for greater clarity. CONCLUSIONS: Based on the feedback received, minor modifications were made, mostly for the self-report. In general, content and face validity for the three instruments were good for both experts and cancer survivors.

RESUMO

PURPOSE: To compare the postoperative side-to-side laxity and short-term clinical outcomes of patients who received primary anterior cruciate ligament (ACL) repair with suture tape augmentation, acute anterior cruciate ligament reconstruction (ACLR) with suture tape augmentation performed within 8 weeks of injury (ACLRacute), or ACLR beyond 8 weeks of injury. METHODS: After institutional review board approval was obtained, 100 patients were enrolled in this prospective trial: 34 primary ACL repair with suture tape augmentation, 33 ACLRs performed within 8 weeks of injury (ACLRacute), and 33 ACLRs. Patients were allocated to ACL repair if a proximal avulsion was present with good tissue quality (Sherman type 1), confirmed by intraoperative diagnostic arthroscopy. Preoperative side-to-side anteroposterior knee laxity was assessed with KT-1000 arthrometer, and patient-reported outcomes (PROs) including the visual analog scale, Marx activity scale, Veterans RAND 12-item health survey (VR-12 physical & mental), Single Assessment Numeric Evaluation, Knee Injury and Osteoarthritis Outcome Score survey subscales, and range of motion were collected. These objective and subjective measures were repeated at regular intervals postoperatively through 2 years. Minimal clinically important difference calculations were performed assessing postoperative PRO changes at 2 years compared with preoperative. RESULTS: The average time from injury to surgery was 5.03 ± 1.2 weeks for the ACL repair group, 5.09 ± 0.74 weeks for the ACLRacute, and 43.22 ± 33.5 weeks for the ACLR group. Postoperatively, the KT-1000 side-to-side laxity difference for 30 lbs was determined to be 0.1 ± 0.37 (95% confidence interval [CI] -0.7 to 0.8) for ACL repair versus ACLR (P < .0001), -0.8 ± 0.35 (95% CI -1.5 to -0.1) for ACLRacute versus ACLR (P < .0001), and 0.8 ± 0.40 (95% CI 0.0-1.6) for ACL repair versus ACLRacute (P < .0001). The data reveal ACL repair and ACLRacute are noninferior to ACLR at 2-year follow-up. The postoperative difference from baseline for all PROs demonstrated improvement for all PROs. Magnetic resonance imaging at 1 year revealed tissue healing for the 3 ACL injury treatment groups. CONCLUSIONS: Patients who underwent ACL repair of proximal tears with suture tape augmentation or ACL reconstruction within 8 weeks from injury resulted in noninferior side-to-side knee laxity, comparable PROs, and similar range of motion at 2-year follow-up compared with ACLR. LEVEL OF EVIDENCE: Level II, prospective comparative study.

RESUMO

PURPOSE: Existing fear of cancer recurrence (FCR) screening measures is being shortened to facilitate clinical use. This study aimed to evaluate the validity and screening capacity of a single-item FCR screening measure (FCR-1r) in long-term colorectal cancer (CRC) survivors with no recurrence and assess whether it performs as well in older as in younger survivors. METHODS: All Danish CRC survivors above 18, diagnosed and treated with curative intent between 2014 and 2018, were located through a national patient registry. A questionnaire including the FCR-1r, which measures FCR on a 0-10 visual analog scale, alongside the validated Fear of Cancer Recurrence Inventory Short Form (FCRI-SF) as a reference standard was distributed between November 2021 and May 2023. Screening capacity and cut-offs were evaluated with a receiver-operating characteristic analysis (ROC) in older (≥ 65 years) compared to younger (< 65 years) CRC survivors. Hypotheses regarding associations with other psychological variables were tested as indicators of convergent and divergent validity. RESULTS: Of the CRC survivors, 2,128/4,483 (47.5%) responded; 1,654 (36.9%) questionnaires were eligible for analyses (median age 76 (range 38-98), 47% female). Of the responders, 85.2% were aged ≥ 65. Ninety-two participants (5.6%) reported FCRI-SF scores ≥ 22 indicating clinically significant FCR. A FCR-1r cut-off ≥ 5/10 had 93.5% sensitivity and 80.4% specificity for detecting clinically significant FCR (AUC = 0.93, 95% CI 0.91-0.94) in the overall sample. The discrimination ability was significantly better in older (AUC = 0.93, 95% CI 0.91-0.95) compared to younger (0.87, 95% (0.82-0.92), p = 0.04) CRC survivors. The FCR-1r demonstrated concurrent validity against the FCRI-SF (r = 0.71, p < 0.0001) and convergent validity against the short-versions of the Symptom Checklist-90-R subscales for anxiety (r = 0.38, p < 0.0001), depression (r = 0.27, p < 0.0001), and emotional distress (r = 0.37, p < 0.0001). The FCR-1r correlated weakly with employment status (r = - 0.09, p < 0.0001) and not with marital status (r = 0.01, p = 0.66) indicating divergent validity. CONCLUSIONS: The FCR-1r is a valid tool for FCR screening in CRC survivors with excellent ability to discriminate between clinical and non-clinical FCR, particularly in older CRC survivors.

RESUMO

OBJECTIVE: Fear of cancer recurrence (FCR) is a common and distressing psychosocial concern for adult cancer survivors. Data on this construct in child survivors is limited and there are no validated measures for this population. This study aimed to adapt the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF) for survivors of childhood cancer aged 8-18 years (Fear of Cancer Recurrence Inventory-Child version [FCRI-C]) and their parents (Fear of Cancer Recurrence Inventory-Parent version [FCRI-P]) to self-report on their own FCR and to examine the initial psychometric properties. METHODS: The FCRI-SF was adapted through expert panel input and cognitive interviews with child survivors <18 years. The factor structure, internal consistency and construct and criterion validity of the FCRI-C and FCRI-P were examined in 124 survivors of childhood cancer (43% female; Mage  = 14.58 years, SD = 2.90) and 106 parents (90% mothers). RESULTS: All FCRI-SF items were retained for the FCRI-C with simplified language. The internal consistencies of the FCRI-C (α = 0.88) and FCRI-P (α = 0.83) were good. Exploratory factor analyses yielded one-factor structures for both measures. Higher scores on the FCRI-C and FCRI-P were associated with greater intolerance of uncertainty and pain catastrophizing. Higher child FCR was also related to more hypervigilance to bodily symptoms. Parents with higher FCR reported contacting their child's doctors and nurses and scheduling medical appointments for their child more frequently. Children reported significantly lower FCR compared to parents. CONCLUSIONS: The FCRI-C and FCRI-P demonstrated strong reliability and preliminary validity. This study offers preliminary data to support the use of the FCRI-C and FCRI-P to measure FCR in survivors of childhood cancer aged 8-18 years and their parents.

RESUMO

OBJECTIVE: Care for fear of cancer recurrence (FCR) is considered the most common unmet need among cancer survivors. Yet the prevalence of FCR and predisposing factors remain inconclusive. To support targeted care, we provide a comprehensive overview of the prevalence and severity of FCR among cancer survivors and patients, as measured using the short form of the validated Fear of Cancer Recurrence Inventory (FCRI-SF). We also report on associations between FCR and clinical and demographic characteristics. METHODS: This is a systematic review and individual participant data (IPD) meta-analysis on the prevalence of FCR. In the review, we included all studies that used the FCRI-SF with adult (≥18 years) cancer survivors and patients. Date of search: 7 February 2020. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal tool. RESULTS: IPD were requested from 87 unique studies and provided for 46 studies comprising 11,226 participants from 13 countries. 9311 respondents were included for the main analyses. On the FCRI-SF (range 0-36), 58.8% of respondents scored ≥13, 45.1% scored ≥16 and 19.2% scored ≥22. FCR decreased with age and women reported more FCR than men. FCR was found across cancer types and continents and for all time periods since cancer diagnosis. CONCLUSIONS: FCR affects a considerable number of cancer survivors and patients. It is therefore important that healthcare providers discuss this issue with their patients and provide treatment when needed. Further research is needed to investigate how best to prevent and treat FCR and to identify other factors associated with FCR. The protocol was prospectively registered (PROSPERO CRD42020142185).

RESUMO

OBJECTIVES: Diagnosis of cancer is emotionally threatening not only for patients but also for their family caregivers (FC) who witness and share much of the illness experience. This study compares distress experienced by lung cancer patients and their FC during the year following the diagnosis. METHODS: A prospective cohort study of 206 patients recently diagnosed with inoperable lung cancer (participation rate 79.5%) and 131 FC (participation rate 63.6%) was conducted in an ambulatory oncology clinic in Quebec City (Canada). They completed validated questionnaires regarding their personal and psychological characteristics (Hospital and Anxiety Depression Scale-HADS), in the first months after the diagnosis of lung cancer and after 6 and 12 months. Univariate, bivariate, and linear mixed models were conducted to compare patient and FC distress. RESULTS: At baseline, 7.8% of patients reported distress (HADS total score >15) and their mean distress score was 7.0 ± 4.9 (range 0-42). In contrast, 33.6% of FC presented significant distress and their mean distress score was 12.0 ± 7.2 (P < 0.0001). Proportions of patients and FC with distress remained relatively stable at 6 and 12 months, and at every time point, FC reported higher levels of distress compared to their relative with cancer (P < 0.0001). Comparable trends were found when looking at the mean scores of distress, anxiety, and depression throughout the study. SIGNIFICANCE OF RESULTS: Being diagnosed with lung cancer and going through its different phases seems to affect more FC than patients. The psychological impact of such diagnosis appears early after the diagnosis and does not significantly change over time. These findings reinforce the importance for oncology teams, to include FC in their systematic distress screening program, in order to help them cope with their own feelings and be able to play their role in patient support and care throughout the cancer journey.

RESUMO

PURPOSE: Collaboration between family physicians (FPs) and oncologists can be challenging. We present the results of a randomized clinical trial of an intervention designed to improve continuity of care and interprofessional collaboration, as perceived by patients with lung cancer and their FPs. METHODS: The intervention included (1) supplying FPs with standardized summaries related to each patient, (2) recommending that patients see their FP after receiving the cancer diagnosis, (3) supplying the oncology team with patient information resulting from FP visits, and (4) providing patients with priority access to FPs as needed. A total of 206 patients with newly diagnosed lung cancer were randomly assigned to the intervention (n = 104) or control group (n = 102), and 86.4% of involved FPs participated. Perceptions of continuity of care and interprofessional collaboration were assessed every 3 months for patients and at baseline and at the end of the study for FPs. Patient distress and health service utilization were also assessed. RESULTS: Patients and FPs in the intervention group perceived better interprofessional collaboration (patients: P <.0001; FPs: P = .0006) than those in the control group. Patients reported better informational continuity (P = .001) and management continuity (P = .05) compared to the control group, but no differences were found for FPs (information: P = .22; management: P = .13). No effect was found with regard to patient distress or health service utilization. CONCLUSIONS: This intervention improved patient and FP perception of interprofessional collaboration, but its effectiveness on continuity of care was less clear for FPs than for patients. Additional strategies should be considered to sustainably improve continuity of care and interprofessional collaboration.

RESUMO

OBJECTIVE: Family caregivers (FCs) of cancer patients often experience high distress. This randomized clinical trial assessed the feasibility and preliminary effects of an intervention to improve FC supportive care. METHOD: A pragmatic and minimal intervention to improve FC supportive care was developed and pretested with FCs, oncology team, and family physicians to assess its relevance and acceptability. Then, FCs of lung cancer patients were randomized to the intervention or the control group. The intervention included (1) systematic FC distress screening and problem assessment in the first months after their relative cancer diagnosis, and every 2 months after; (2) privileged contact with an oncology nurse to address FC problems, provide emotional support and skills to play their caregiving role; (3) liaison with the family physician of FCs reporting high distress (distress thermometer score ≥4/10) to involve them in the provision of supportive care. Distress, the primary outcome, was measured every 3 months, for 9 months. Secondary outcomes included quality of life, caregiving preparedness, and perceived burden. At the end of their participation, a purposive sample of FC from the experimental group was individually interviewed to assess the intervention usefulness. Content analysis was performed. RESULTS: A total of 109 FCs participated in the trial. FC distress decreased over time, but this reduction was observed in both groups. Similar results were found for secondary outcomes. However, FCs who received the intervention felt better prepared in caregiving than controls (p = 0.05). All 10 interviewed FCs valued the intervention, even though they clearly underused it. Knowing they could contact the oncology nurse served as a security net. SIGNIFICANCE OF RESULTS: Although the intervention was not found effective, some of its aspects were positively perceived by FCs. As many of them experience high distress, an improved intervention should be developed to better support them.

RESUMO

OBJECTIVE: The purposes of this study were to develop a Chinese version of the Fear of Cancer Recurrence Inventory-caregiver (FCRI-c Chinese) and assess the psychometrics of this test in the family caregivers (FCs) of Taiwanese patients with head and neck cancer. METHODS: An instrument testing study was conducted at a major medical center in Taiwan. Head and neck cancer patients and their major FCs were recruited as dyads from the radiation outpatient department. The FCRI-c Chinese was tested for internal consistency reliability, test-retest reliability, and construct validity (including theoretically supported correlation, discriminant validity, and factor structure). RESULTS: We recruited 300 patient-caregiver dyads. The test had good internal consistency (Cronbach α = .94) and a 2-week test-retest reliability of .88. Confirmatory factor analysis indicated an acceptable fit of the model to the data. The construct validity was also satisfactory, as indicated by the significant positive correlations of the test with depression and anxiety in FCs, and the significant negative correlation of the test with patients' quality of life. A significantly higher test score was present in FCs caring for patients with metastasis and patients who completed treatment a long time ago. CONCLUSIONS: The FCRI-c Chinese is a valid instrument for examination of the fear of cancer recurrence in the FCs of patients with head and neck cancer. Clinicians can use this multidimensional instrument to assess important clinical care issues and improve the quality of care provided by FCs.

RESUMO

OBJECTIVE: Fear of cancer recurrence (FCR) is a common concern among cancer survivors. Identifying survivors with clinically significant FCR requires validated screening measures and clinical cut-offs. We evaluated the Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF) clinical cut-off in 2 samples. METHODS: Level of FCR in study 1 participants (from an Australian randomized controlled trial: ConquerFear) was compared with FCRI-SF scores. Based on a biopsychosocial interview, clinicians rated participants as having nonclinical, subclinical, or clinical FCR. Study 2 participants (from a Canadian FCRI-English validation study) were classified as having clinical or nonclinical FCR by using the semistructured clinical interview for FCR (SIFCR). Receiver operating characteristic analyses evaluated the screening ability of the FCRI-SF against clinician ratings (study 1) and the SIFCR (study 2). RESULTS: In study 1, 167 cancer survivors (mean age: 53 years, SD = 10.1) participated. Clinicians rated 43% as having clinical FCR. In study 2, 40 cancer survivors (mean age: 68 years, SD = 7.0) participated; 25% met criteria for clinical FCR according to the SIFCR. For both studies 1 and 2, receiver operating characteristic analyses suggested a cut-off ≥22 on the FCRI-SF identified cancer survivors with clinical levels of FCR with adequate sensitivity and specificity. CONCLUSIONS: Establishing clinical cut-offs on FCR screening measures is crucial to tailoring individual care and conducting rigorous research. Our results suggest using a higher cut-off on the FCRI-SF than previously reported to identify clinically significant FCR. Continued evaluation and validation of the FCRI-SF cut-off is required across diverse cancer populations.

RESUMO

Fear of cancer recurrence (FCR) is one of the most prevalent unmet psychosocial needs. This study aimed to confirm the cultural equivalence, reliability, and validity of the Korean version of Fear of Cancer Recurrence Inventory (K-FCRI). We conducted a forward-backward translation of the English version FCRI to Korean version through meticulous process including transcultural equivalence test. The psychometric property of the K-FCRI was then validated in 444 survivors from cancers at various sites. The Korean translation was accepted well by participants. There was a good cultural equivalence between the Korean version and the English version of FCRI. Confirmatory factor analysis supported the original seven-factor structure with slightly insufficient level of goodness-of-fit indices (comparative fit index = 0.900, non-normed fit index = 0.893, root mean square error of approximation = 0.060). The K-FCRI had high internal consistency (α = 0.85 for total scale and α = 0.77-0.87 for subscales) and test-retest reliability (r = 0.90 for total scale and r = 0.54-0.84 for subscales). The K-FCRI had significant correlations with the Korean version of Fear of Progression Questionnaire, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Version 3.0, Hospital Anxiety and Depression Scale, and Fatigue Severity Score, supporting the good construct validity and psychometric properties of K-FCRI. The K-FCRI was confirmed as a valid and reliable psychometric test for measuring FCR of Korean survivors from cancers at various sites.

RESUMO

BACKGROUND: Microglial cells are tissue-resident macrophages of the central nervous system. They are extremely dynamic, sensitive to their microenvironment and present a characteristic complex and heterogeneous morphology and distribution within the brain tissue. Many experimental clues highlight a strong link between their morphology and their function in response to aggression. However, due to their complex "dendritic-like" aspect that constitutes the major pool of murine microglial cells and their dense network, precise and powerful morphological studies are not easy to realize and complicate correlation with molecular or clinical parameters. METHODS: Using the knock-in mouse model CX3CR1(GFP/+), we developed a 3D automated confocal tissue imaging system coupled with morphological modelling of many thousands of microglial cells revealing precise and quantitative assessment of major cell features: cell density, cell body area, cytoplasm area and number of primary, secondary and tertiary processes. We determined two morphological criteria that are the complexity index (CI) and the covered environment area (CEA) allowing an innovative approach lying in (i) an accurate and objective study of morphological changes in healthy or pathological condition, (ii) an in situ mapping of the microglial distribution in different neuroanatomical regions and (iii) a study of the clustering of numerous cells, allowing us to discriminate different sub-populations. RESULTS: Our results on more than 20,000 cells by condition confirm at baseline a regional heterogeneity of the microglial distribution and phenotype that persists after induction of neuroinflammation by systemic injection of lipopolysaccharide (LPS). Using clustering analysis, we highlight that, at resting state, microglial cells are distributed in four microglial sub-populations defined by their CI and CEA with a regional pattern and a specific behaviour after challenge. CONCLUSIONS: Our results counteract the classical view of a homogenous regional resting state of the microglial cells within the brain. Microglial cells are distributed in different defined sub-populations that present specific behaviour after pathological challenge, allowing postulating for a cellular and functional specialization. Moreover, this new experimental approach will provide a support not only to neuropathological diagnosis but also to study microglial function in various disease models while reducing the number of animals needed to approach the international ethical statements.

RESUMO

PURPOSE: Fear of cancer recurrence (FCR) is a common experience for cancer survivors. However, it remains unclear what characteristics differentiate non-clinical from clinical levels of FCR. The goal of this study was to investigate the potential hallmarks of clinical FCR. METHODS: A convenience sample of 40 participants (n = 19 female) was drawn from another study (Lebel et al. in Qual Life Res 25:311-321. doi: 10.1007/s11136-015-1088-2 , 2016). The semi-structured interview for fear of cancer recurrence (Simard and Savard in J Cancer Surviv 9:481-491. doi: 10.1007/s11764-015-0424-4 , 2015) was used to identify participants with non-clinical and clinical FCR and qualitative analysis of these interviews was performed. RESULTS: Individuals with clinical FCR reported the following features: death-related thoughts, feeling alone, belief that the cancer would return, experiencing intolerance of uncertainty, having cancer-related thoughts and imagery that were difficult to control, daily and recurrent, lasted 30 minutes or more, increased over time, caused distress and impacted their daily life. Triggers of FCR and coping strategies did not appear to be features of clinical FCR as they were reported by participants with a range of FCR scores. CONCLUSIONS: While features of clinical FCR found in this analysis such as intrusive thoughts, distress and impact on functioning confirmed previous FCR research, other features spontaneously emerged from the interviews including "death-related thoughts," "feeling alone," and "belief that the cancer will return." The participants' descriptions of cancer-specific fear and worry suggest that FCR is a distinct phenomenon related to cancer survivorship, despite similarities with psychological disorders (e.g., Anxiety Disorders). Future research investigating the construct of FCR, and the distinguishing features of clinical FCR across a range of cancer types and gender is required.

RESUMO

PURPOSE: Cancer patients report that help in managing fear of cancer recurrence (FCR) is one of their greatest unmet needs. Research on FCR has been limited by the very few validated, multi-dimensional measures of this construct. One exception is the Fear of Cancer Recurrence Inventory (FCRI), originally developed and empirically validated in French. The present study validated the English version of the FCRI. METHODS: The FCRI was translated into English using a forward-backward translation procedure and pilot-tested with 17 English-speaking cancer patients. Cross-cultural equivalency of the French and English versions was established by administering both forms to 42 bilingual cancer patients. Last, 350 English-speaking breast, colon, prostate, or lung cancer patients were asked to complete the FCRI. A subsample (n = 135) was mailed the FCRI again one month later to evaluate test-retest reliability. RESULTS: The English translation of the FCRI was well accepted by participants. There was no item-bias when comparing bilingual participants' answers on both versions. A confirmatory factor analysis supported the hypothesized seven-factor structure. The English version has high internal consistency (α = .96 for the total scale and .71-.94 for the subscales) and test-retest reliability (r = .88 for the total scale and 56-.87 for the subscales). CONCLUSIONS: The English version of the FCRI is a reliable and valid measure of FCR applicable to breast, colon, prostate, and lung cancer patients. Its multi-dimensional nature makes it an attractive research and clinical tool to further our knowledge of FCR.

RESUMO

OBJECTIVE: Fear of cancer recurrence or progression (FCR) is considered one of the most common unmet needs among patients with cancer. This study sought to translate and evaluate the psychometric properties of the Fear of Cancer Recurrence scale (FCR4/7) and Fear of Cancer Recurrence Inventory-Short Form (FCRI-SF). METHODS: This study involved three phases: (1) translation and cultural adaptation of the FCR4/7 and FCRI-SF measures, (2) validity and reliability testing of the Portuguese version of these measures, and (3) examining patient's perceptions of these measures. Eligible patients were diagnosed with localized breast cancer, and patients with metastatic cancer. Descriptive analyses were collated, and psychometric analysis were conducted (confirmatory factor analysis). RESULTS: A total of 200 patients were recruited (100 patients with localized and 100 patients with metastatic cancer). A significant proportion of patients reported moderate to severe FCR (FCR7: 32.0% and FCRI-SF: 43.0%). Female gender, younger age and metastatic cancer were associated with higher levels of FCR. Psychometric analyses suggested that the Portuguese versions of the FCR4/7 and FCRI-SF were valid, unidimensional in nature, with acceptable reliability coefficients across all scales. In a sub-sample qualitative analysis (n = 75), most patients were satisfied with the relevance of both measures. CONCLUSION: Our findings suggest the Portuguese versions of the FCR4/7 and FCRI-SF are valid tools to assess FCR among patients with localized and metastatic cancer. Future research can now extend our understanding of FCR and assess this construct among Portuguese speaking patients, to guide the development of effective and targeted interventions for patients globally.

RESUMO

BACKGROUND: Fear of disease recurrence is well documented among cancer survivors, but its significance among patients treated for solid pancreatic and periampullary neoplasms is unknown despite the known risk of recurrence associated with these tumors. We hypothesized that fear of cancer recurrence (FCR) represents a common source of psychosocial distress in this population and sought to characterize subgroups for whom FCR might represent a target for intervention to improve quality of life. METHODS: We conducted a cross-sectional study of FCR in patients who were disease-free after potentially curative pancreatectomy for ductal or periampullary adenocarcinoma or pancreatic neuroendocrine tumor. We assessed seven discrete dimensions of FCR using the Fear of Recurrence Inventory and evaluated quality of life and psychosocial distress using the Functional Assessment of Cancer Therapy-Hepatobiliary Questionnaire and the Hospital Anxiety and Depression Scale. RESULTS: Of 354 eligible patients, 240 (68 %) participated in the study a median of 48 months after potentially curative pancreatectomy. An FCR severity score indicative of frequent fearful thoughts, emotional disturbance and functional impairment was identified in 37, 28, and 35 % of patients with pancreatic adenocarcinoma, nonpancreatic periampullary adenocarcinoma, and pancreatic neuroendocrine tumor, respectively. Anxiety (P < 0.001) and low quality of life (P = 0.028) were independently associated with a clinically significant level of FCR, but histopathologic diagnosis and clinicopathologic markers of prognosis were not. CONCLUSIONS: FCR represents a significant concern for one-third of patients after curative surgery for a pancreatic or periampullary tumor, regardless of their actual likelihood of recurrence or disease-related death.

RESUMO

BACKGROUND: Prior research has shown that many cancer survivors experience ongoing fears of cancer recurrence (FCR) and that this chronic uncertainty of health status during and after cancer treatment can be a significant psychological burden. The field of research on FCR is an emerging area of investigation in the cancer survivorship literature, and several standardised instruments for its assessment have been developed. AIMS: This review aims to identify all available FCR-specific questionnaires and subscales and critically appraise their properties. METHODS: A systematic review was undertaken to identify instruments measuring FCR. Relevant studies were identified via Medline (1950-2010), CINAHL (1982-2010), PsycINFO (1967-2010) and AMED (1985-2010) databases, reference lists of articles and reviews, grey literature databases and consultation with experts in the field. The Medical Outcomes Trust criteria were used to examine the psychometric properties of the questionnaires. RESULTS: A total of 20 relevant multi-item measures were identified. The majority of instruments have demonstrated reliability and preliminary evidence of validity. Relatively few brief measures (2-10 items) were found to have comprehensive validation and reliability data available. Several valid and reliable longer measures (>10 items) are available. Three have developed short forms that may prove useful as screening tools. CONCLUSIONS: This analysis indicated that further refinement and validation of existing instruments is required. Valid and reliable instruments are needed for both research and clinical care.

RESUMO

OBJECTIVE: The present study aims to document the frequency of use of hypnotic medication among a large sample of randomly selected patients having been treated for various types of cancer, as well as to identify the sociodemographic, psychosocial, and medical factors that characterize the users of this type of medication. METHODS: Five thousand patients who had received treatment for breast, prostate, lung, or colorectal cancer at the L'Hôtel-Dieu de Québec were solicited by mail to take part in this study. Among these patients, 1,984 (39.7%) agreed to complete a battery of questionnaires. RESULTS: Overall, 22.6% of the patients were currently consuming hypnotic medication. Factors associated with a greater utilization of hypnotic medication were older age, greater difficulties initiating sleep, more stressful life events experienced in the past 6 months, higher levels of anxiety, past or current psychological difficulties, poorer role functioning, less severe urinary symptoms, greater use of opioids, and past or current chemotherapy treatments. CONCLUSIONS: These results are consistent with those of previous studies conducted in cancer patients in showing high rates of hypnotic medication use. Moreover, this study identified several factors that might help identify persons at risk of using this type of medication and, therefore, to experience the potential negative effects of chronic hypnotics use.

RESUMO

The objective of this exploratory study was to evaluate the impact of advanced parental cancer on adolescents' psychological status. A sample of 28 adolescents, having a parent with advanced cancer, was recruited and compared with a sample from the general population (N = 2,346). Late adolescents (age 15 to 18) experienced significantly more psychological distress than early adolescents (age 12 to 14). Moreover, late adolescents experienced significantly higher psychological distress than the general population for the same age group, which was not the case for early adolescents. Implications for adolescents living in families touched by advanced cancer are discussed.

RESUMO

OBJECTIVES: Theoretical models suggest that anxiety, pain intensity, and pain catastrophizing are implicated in a cycle that leads to heightened fear of cancer recurrence (FCR). However, these relationships have not been empirically examined. The objective of this study was to examine the relationships between anxiety symptoms, pain intensity, pain catastrophizing, and FCR in childhood cancer survivors and their parents and to examine whether pain catastrophizing predicts increased FCR beyond anxiety symptoms and pain intensity. METHODS: The participants were 54 survivors of various childhood cancers (Mage=13.1 y, range=8.4 to 17.9 y, 50% female) and their parents (94% mothers). Children reported on their pain intensity in the past 7 days. Children and parents separately completed measures of anxiety symptoms, pain catastrophizing, and FCR. RESULTS: Higher anxiety symptoms were associated with increased pain intensity, pain catastrophizing, and FCR in childhood cancer survivors. Higher anxiety symptoms and pain catastrophizing, but not child pain intensity, were associated with FCR in parents. Hierarchical linear regression models revealed that pain catastrophizing explained unique variance in both parent (ΔR2=0.11, P<0.01) and child (ΔR2=0.07, P<0.05) FCR over and above the effects of their own anxiety symptoms and child pain. DISCUSSION: The results of this study provides novel data on the association between pain and FCR and suggests that a catastrophic style of thinking about pain is more closely related to heightened FCR than one's anxiety symptoms or the sensory pain experience in both childhood cancer survivors and their parents. Pain catastrophizing may be a novel intervention target for survivors and parents struggling with fears of recurrence.
