Prevalence of Lymphedema in Women With Breast Cancer 5 Years After Sentinel Lymph Node Biopsy or Axillary Dissection: Objective Measurements

PURPOSE Sentinel lymph node biopsy was adopted for the staging of the axilla with the assumption that it would reduce the risk of lymphedema in women with breast cancer. The aim of this study was to determine the long-term prevalence of lymphedema after SLN biopsy (SLNB) alone and after SLNB followed by axillary lymph node dissection (SLNB/ALND). PATIENTS AND METHODS At median follow-up of 5 years, lymphedema was assessed in 936 women with clinically node-negative breast cancer who underwent SLNB alone or SLNB/ALND. Standardized ipsilateral and contralateral measurements at baseline and follow-up were used to determine change in ipsilateral upper extremity circumference and to control for baseline asymmetry and weight change. Associations between lymphedema and potential risk factors were examined. RESULTS Of the 936 women, 600 women (64%) underwent SLNB alone and 336 women (36%) underwent SLNB/ALND. Patients having SLNB alone were older than those having SLNB/ALND (56 v 52 years; P < .0001). Baseline body mass index (BMI) was similar in both groups. Arm circumference measurements documented lymphedema in 5% of SLNB alone patients, compared with 16% of SLNB/ALND patients (P < .0001). Risk factors associated with measured lymphedema were greater body weight (P < .0001), higher BMI (P < .0001), and infection (P < .0001) or injury (P = .02) in the ipsilateral arm since surgery. CONCLUSION When compared with SLNB/ALND, SLNB alone results in a significantly lower rate of lymphedema 5 years postoperatively. However, even after SLNB alone, there remains a clinically relevant risk of lymphedema. Higher body weight, infection, and injury are significant risk factors for developing lymphedema.

Prevalence of Lymphedema in Women With Breast Cancer 5 Years After Sentinel Lymph Node Biopsy or Axillary Dissection: Patient Perceptions and Precautionary Behaviors

PURPOSE Sentinel lymph node (SLN) biopsy was adopted for the staging of the axilla with the assumption that it would reduce the risk of lymphedema in women with breast cancer. This study was undertaken to examine patient perceptions of lymphedema and use of precautionary behaviors several years after axillary surgery. PATIENTS AND METHODS Nine hundred thirty-six women who underwent SLN biopsy (SLNB) alone or SLNB followed by axillary lymph node dissection (SLNB/ALND) between June 1, 1999, and May 30, 2003, were evaluated at a median of 5 years after surgery. Patient-perceived lymphedema and avoidant behaviors were assessed through interview and administered a validated instrument, and compared with arm measurements. RESULTS Current arm swelling was reported in 3% of patients who received SLNB alone versus 27% of patients who received SLNB/ALND (P < .0001), as compared with 5% and 16%, respectively, with measured lymphedema. Only 41% of patients reporting arm swelling had measured lymphedema, and 5% of patients reporting no arm swelling had measured lymphedema. Risk factors associated with reported arm swelling were greater body weight (P < .0001), higher body mass index (P < .0001), infection (P < .0001), and injury (P = .007) in the ipsilateral arm since surgery. Patients followed more precautions if they had measured or perceived lymphedema. CONCLUSION Body weight, infection, and injury are significant risk factors for perceiving lymphedema. There is significant discordance between the presence of measured and patient-perceived lymphedema. When compared to SLNB/ALND, SLNB-alone results in a significantly lower rate of patient-perceived arm swelling 5 years postoperatively, and is perceived by fewer women than are measured to have it.

Construct Validity of the Posttraumatic Stress Disorder Checklist in Cancer Survivors: Analyses Based on Two Samples.

The measurement of posttraumatic stress disorder (PTSD) is critically important for the identification and treatment of this disorder. The PTSD Checklist (PCL; F. W. Weathers and J. Ford, 1996) is a self-report measure that is increasingly used. In this study, the authors investigated the factorial validity of the PCL with data from 236 cancer survivors who received a bone marrow or stem cell transplantation. The authors examined the fit of these data with the clinical model of 3 symptom clusters for PTSD, as proposed in the Diagnostic and Statistical Manual of Mental Disorders, and alternative models tested in prior research. By using confirmatory factor analysis the authors found that a 4-first-order-factor model of PTSD provided the best fit. The relations of PTSD symptoms with sociodemographic and medical variables were also explored.

Genome-Wide Association Studies of Cancer

Knowledge of the inherited risk for cancer is an important component of preventive oncology. In addition to well-established syndromes of cancer predisposition, much remains to be discovered about the genetic variation underlying susceptibility to common malignancies. Increased knowledge about the human genome and advances in genotyping technology have made possible genome-wide association studies (GWAS) of human diseases. These studies have identified many important regions of genetic variation associated with an increased risk for human traits and diseases including cancer. Understanding the principles, major findings, and limitations of GWAS is becoming increasingly important for oncologists as dissemination of genomic risk tests directly to consumers is already occurring through commercial companies. GWAS have contributed to our understanding of the genetic basis of cancer and will shed light on biologic pathways and possible new strategies for targeted prevention. To date, however, the clinical utility of GWAS-derived risk markers remains limited.

Randomized Clinical Trial of Telephone-Administered Cognitive-Behavioral Therapy to Reduce Post-Traumatic Stress Disorder and Distress Symptoms After Hematopoietic Stem-Cell Transplantation

PURPOSE A significant number of survivors of hematopoietic stem-cell transplantation (HSCT) report enduring adverse effects of treatment, including illness-related post-traumatic stress disorder (PTSD) symptoms and general distress. We report results of a randomized clinical trial that tested the effects of a 10-session, telephone-administered cognitive-behavioral therapy (CBT) intervention on PTSD, depression, and distress symptoms. METHODS Survivors who had undergone HSCT 1 to 3 years earlier (N = 408) were assessed for study eligibility. Those who met study eligibility criteria (n = 89) completed a baseline assessment that included a clinical interview and self-report measures of PTSD symptoms (the primary outcome) and depression and general distress (the secondary outcomes). Next, they were randomly assigned to CBT or an assessment-only condition. Survivors in the CBT group completed 10 individual telephone-based CBT sessions (T-CBT) that included strategies to reduce PTSD symptoms, depression, and general distress. Follow-up assessments occurred at 6, 9, and 12 months after the baseline assessment. RESULTS Linear mixed-model analyses revealed that, compared with HSCT survivors in the assessment-only condition, survivors who completed T-CBT reported fewer illness-related PTSD symptoms, including less avoidance (P < .001) and fewer intrusive thoughts (P < .05) as well as less general distress and fewer depressive symptoms (P < .05) even after controlling for potential demographic and medical covariates. These results were consistent across the three follow-up assessments. CONCLUSION A brief, telephone-administered CBT intervention developed for HSCT survivors is an efficacious treatment for reducing illness-related PTSD symptoms and general distress.

Pre- and postmenopausal high-risk women undergoing screening for ovarian cancer: anxiety, risk perceptions, and quality of life.

OBJECTIVE Recommendations for women at high risk of ovarian cancer include prophylactic salpingo-oophorectomy (PSO) or screening with transvaginal ultrasonography (TVUS) and CA125 levels. The best strategy for improving survival and maintaining quality of life in high-risk women is not known. Premenopausal women may be more reluctant than postmenopausal women to undergo PSO. However, the risk of false-positive screening results may be more likely in premenopausal women, posing potential psychological risk for those enrolled in high-risk ovarian cancer surveillance programs. We sought to determine whether anxiety, depression, perception of ovarian cancer risk, and false-positive test frequency differed between high-risk premenopausal and postmenopausal women initiating ovarian cancer screening. METHODS High-risk women aged > or = 30 years enrolling in a TVUS plus CA125 ovarian cancer screening study completed standard QOL (SF-36), cancer-specific anxiety (IES), depression (CES-D), and ovarian cancer risk perception measures. CA125 > 35 and TVUS showing solid or complex cystic ovarian masses were considered abnormal. Abnormal tests were repeated after 4-6 weeks. Persistently abnormal tests prompted a search for malignancy. Tests that normalized on repeat were considered false positive. RESULTS One hundred forty-seven high-risk women, median age 46 (range, 30-78), 78 premenopausal and 69 postmenopausal, had > or = 1 TVUS/CA125/outcome assessment. Premenopausal women were more likely than postmenopausal women to consider themselves at higher risk of ovarian cancer compared with women their age (P < 0.001) and compared with women with similar family histories (P < 0.001). Mean personal perception of lifetime risk of ovarian cancer among premenopausal women was 37% (range, 0-90%) versus 26% (range, 0-60%) among postmenopausal women (P = 0.02). While general QOL and depression scores were similar, 38% of premenopausal women reported high anxiety versus 27% of postmenopausal women (P = 0.03). Thirty percent of women required repeat CA125 or TVUS after first screening; 10.8% of premenopausal women versus 4.6% of postmenopausal women required repeat CA125; and 23.3% of premenopausal and 20.6% of postmenopausal women required repeat TVUS. One postmenopausal woman with persistently rising CA125 >100 had negative mammography, colonoscopy, and dilation and curettage/bilateral salpingo-oophorectomy. All other abnormal tests normalized on repeat. Two premenopausal women withdrew due to anxiety following false-positive CA125 results. Five women (2 premenopausal, 3 postmenopausal) with normal TVUS/CA125 screening tests elected PSO, with benign findings. CONCLUSION Premenopausal women perceive their ovarian cancer risk to be higher, report greater ovarian cancer risk-related anxiety, and are more likely to have false-positive screening results than postmenopausal women. Few high-risk women elect PSO in the short term. Knowledge of the frequency of false-positive screening results and psychosocial outcomes is important for high-risk women choosing strategies for managing ovarian cancer risk.

A prospective study of quality of life in patients undergoing pelvic exenteration: Interim results

OBJECTIVE Little prospective data exist on quality of life (QOL) after pelvic exenteration (PE). This ongoing study prospectively examines the QOL changes following this radical procedure using a comprehensive battery of psychological instruments. METHODS Since 2005, enrolled patients were interviewed (EORTC QLQ-C30, EORTC QLQ-CR38, EORTC QLQ-BLM30, BFI, BPI-SF, IADL, CES-D, IES-R) preoperatively and at 3, 6, and 12 months after PE for physical/psychological symptoms. Data were examined using repeated measure ANOVA. RESULTS Sixteen women (3 anterior, 1 posterior, and 12 total PEs), with more than 1 year of follow-up, completed all scheduled interviews. Median age was 58 years (range, 28-76 years). Overall QOL (F = 6.3, p < 0.02), ability to perform instrumental daily activities (F = 6.8, p < 0.02), body image (F = 11.9, p < 0.00), and sexual function (F = 8.0, p < 0.01) all declined at 3 months but were near baseline by 12 months after PE. Although, overall, physical function followed a similar trend (F = 14.8, p < 0.00), it did not return to baseline. At the 12-month interview, patients reported increased gastrointestinal symptoms (F = 8.9, p < 0.01) but significantly less stress-related ideation (F = 6.1, p < 0.03) compared to baseline. Pain levels did not change significantly during the study period (F = 0.4, p < 0.74). CONCLUSIONS Although patients report lingering gastrointestinal symptoms and some persistent decline in physical function after PE, most adjust well, returning to almost baseline functioning within a year. Providers can counsel patients that many, though not all, symptoms in the first 3 months following exenteration are likely to improve as they adapt to their changed health status. These preliminary results await confirmation of a larger analysis.

Cognitive functions in long-term survivors of ovarian cancer

BACKGROUND Women diagnosed with ovarian cancer often undergo chemotherapy involving multiple agents. However, little is known about the incidence of cognitive adverse effects of chemotherapy in survivors of this disease. This cross-sectional study assessed neuropsychological functions in long-term survivors of ovarian cancer who were either in complete remission or with evidence of recurrent disease. METHODS Forty-eight women diagnosed with ovarian cancer 5 to 10 years prior to study enrollment underwent a brief neuropsychological evaluation; 22 patients were disease free and without history of recurrence (Group 1), and 26 patients had recurrent disease and were receiving treatment with chemotherapy or hormonal therapy (Group 2). RESULTS There were no statistically significant differences between the two patient groups on tests of attention, memory, and executive functions. Group mean cognitive test scores were within the average range on all tests; however 28% of patients met criteria for cognitive impairment, a significantly higher frequency (p=0.03) than reported in healthy populations. CONCLUSIONS In this study, neuropsychological test performance did not differ significantly between ovarian cancer survivors who were in remission and patients with recurrent disease and receiving treatment. Cognitive impairment was evident in a subset of patients, although group means test scores were within the average range. Additional research using prospective longitudinal designs is needed to clarify the contribution of disease, chemotherapy, hormonal therapy, and other risk factors to cognitive outcome in this clinical population.

Incorporating Information Regarding Preimplantation Genetic Diagnosis Into Discussions Concerning Testing and Risk Management for BRCA1/2 Mutations A Qualitative Study of Patient Preferences

Studies have shown that BRCA1/2 mutation carriers are interested in learning about reproductive options such as preimplantation genetic diagnosis (PGD) to prevent passing their risk onto their children. However, attitudes vary widely, and the procedure raises complex ethical and psychosocial issues. This complexity, plus the highly technical nature of PGD, makes it difficult to integrate PGD information into genetic counseling sessions that already cover probabilistic, emotionally charged risk information.

Traceback: A Proposed Framework to Increase Identification and Genetic Counseling of BRCA1 and BRCA2 Mutation Carriers Through Family-Based Outreach

In May 2016, the Division of Cancer Prevention and the Division of Cancer Control and Population Sciences, National Cancer Institute, convened a workshop to discuss a conceptual framework for identifying and genetically testing previously diagnosed but unreferred patients with ovarian cancer and other unrecognized BRCA1 or BRCA2 mutation carriers to improve the detection of families at risk for breast or ovarian cancer. The concept, designated Traceback, was prompted by the recognition that although BRCA1 and BRCA2 mutations are frequent in women with ovarian cancer, many such women have not been tested, especially if their diagnosis predated changes in testing guidelines. The failure to identify mutation carriers among probands represents a lost opportunity to prevent cancer in unsuspecting relatives through risk-reduction intervention in mutation carriers and to provide appropriate reassurances to noncarriers. The Traceback program could provide an important opportunity to reach families from racial, ethnic, and socioeconomic groups who historically have not sought or been offered genetic counseling and testing and thereby contribute to a reduction in health disparities in women with germline BRCA mutations. To achieve an interdisciplinary perspective, the workshop assembled international experts in genetics, medical and gynecologic oncology, clinical psychology, epidemiology, genomics, cost-effectiveness modeling, pathology, bioethics, and patient advocacy to identify factors to consider when undertaking a Traceback program. This report highlights the workshop deliberations with the goal of stimulating research and providing a framework for pilot studies to assess the feasibility and ethical and logistical considerations related to the development of best practices for implementation of Traceback studies.
