Better Survival in Patients with Esophageal Cancer After Surgical Treatment in University Hospitals: A Plea for Performance by Surgical Oncologists

Background: In primary esophageal cancer, studies have frequently focused on surgical patients in an effort to link outcome to hospital- or surgeon-related experience, with operative mortality used as the main outcome measure. Many studies have found an inverse relationship between operative mortality and hospital volume and surgical expertise. This study aims to assess the influence of surgeon-related expertise and hospital volume on the relative survival of operated esophageal cancer patients. Methods: From January 1994 to January 2002, a total of 1149 consecutive patients with primary esophageal cancer were diagnosed in the region of the Comprehensive Cancer Center North-Netherlands. As a proxy for surgeon-related expertise, hospitals in this region were categorized into three types: university, teaching nonuniversity, and nonteaching hospitals. The influence of hospital type on the relative survival of operated patients was studied by a multivariate Poisson regression model. Results: Of the 1149 patients, 18.5% underwent surgery. There was no evidence of selective referral for surgery between the three hospital types with regard to age, tumor stage, and location. For operated patients, the 5-year relative survival was 49.2% for the university hospital versus 32.6% and 27.3% for teaching nonuniversity and nonteaching hospitals, respectively (P = .0039). When adjusted for age, tumor stage, hospital volume and referral frequency, the relative excess risk of death for the university hospital was considerably lower at .57 (95% confidence interval, .29-1.12) compared with nonteaching hospitals and .43 (95% confidence interval, .24-.76) compared with teaching nonuniversity hospitals (P = .0126). Conclusions: In our region, patients with esophageal cancer who underwent esophagectomy in the university hospital had a markedly better relative survival compared with those who underwent surgery at teaching nonuniversity and nonteaching hospitals, emphasizing the need for referral of esophageal surgery to centers with a greater experience

Underuse of long-term routine hospital follow-up care in patients with a history of breast cancer?

Background: After primary treatment for breast cancer, patients are recommended to use hospital follow-up care routinely. Long-term data on the utilization of this follow-up care are relatively rare. Methods: Information regarding the utilization of routine hospital follow-up care was retrieved from hospital documents of 662 patients treated for breast cancer. Utilization of hospital follow-up care was defined as the use of follow-up care according to the guidelines in that period of time. Determinants of hospital follow up care were evaluated with multivariate analysis by generalized estimating equations (GEE). Results: The median follow-up time was 9.0 (0.3-18.1) years. At fifth and tenth year after diagnosis, 16.1% and 33.5% of the patients had less follow-up visits than recommended in the national guideline, and 33.1% and 40.4% had less frequent mammography than recommended. Less frequent mammography was found in older patients (age > 70; OR: 2.10; 95%CI: 1.62-2.74), patients with comorbidity (OR: 1.26; 95%CI: 1.05-1.52) and patients using hormonal therapy (OR: 1.51; 95%CI: 1.01-2.25). Conclusions: Most patients with a history of breast cancer use hospital follow-up care according to the guidelines. In older patients, patients with comorbidity and patients receiving hormonal therapy yearly mammography is performed much less than recommended

Changes in employment status, barriers to, and facilitators of (return to) work in breast cancer survivors 5-10 years after diagnosis

Purpose: To qualitatively investigate changes in employment status, barriers to and facilitators of (return to) work in breast cancer survivors 5-10 years after diagnosis. Materials and methods: Women were eligible to participate in the focus groups if they were younger than 55 years and were employed at time of diagnosis. Data were analysed by two independent researchers using thematic content analysis. Results: Nineteen women participated in three semi-structured focus groups, of whom 18 reported a change in employment status 5-10 years after diagnosis. Perceived barriers to (return to) work shortly after breast cancer diagnosis tended to be disease- and treatment-related, while 5-10 years later, they were personal- and work-related. Participants recommended open communication and support at the workplace, and comprehensive information from (occupational) health care professionals to facilitate dealing with breast cancer at work. Conclusions: Breast cancer survivors still experience changes in employment status 5-10 years after diagnosis. (Occupational) health care professionals should be alert that perceived barriers for returning to work change over time. Future research should focus on increasing awareness (at work) of breast cancer survivors' needs, providing adequate information and support to all involved, and developing interventions to sustain survivors' work ability at the long term.</p

Risk of heart failure in survivors of Hodgkin lymphoma: Effects of cardiac exposure to radiation and anthracyclines

Hodgkin lymphoma (HL) survivors treated with radiotherapy and/or chemotherapy are known to have increased risks of heart failure (HF), but a radiation dose-response relationship has not previously been derived. A case-control study, nested in a cohort of 2617 five-year survivors of HL diagnosed before age 51 years during 1965 to 1995, was conducted. Cases (n 5 91) had moderate or severe HF as their first cardiovascular diagnosis. Controls (n 5 278) were matched to cases on age, sex, and HL diagnosis date. Treatment and follow-up information were abstracted from medical records. Mean heart doses and mean left ventricular doses (MLVD) were estimated by reconstruction of individual treatments on representative computed tomography datasets. Average MLVD was 16.7 Gy for cases and 13.8 Gy for controls (Pdifference 5 .003). HF rate increased with MLVD: relative to 0 Gy, HF rates following MVLD of 1-15, 16-20, 21-25, and ≥26 Gy were 1.27, 1.65, 3.84, and 4.39, respectively (Ptrend < .001). Anthracycline-containing chemotherapy increased HF rate by a factor of 2.83 (95% CI: 1.43-5.59), and there was no significant interaction with MLVD (Pinteraction 5 .09). Twenty-five–year cumulative risks of HF following MLVDs of 0-15 Gy, 16-20 Gy, and ≥21 Gy were 4.4%, 6.2%, and 13.3%, respectively, in patients treated without anthracycline-containing chemotherapy, and 11.2%, 15.9%, and 32.9%, respectively, in patients treated with anthracyclines. We have derived quantitative estimates of HF risk in patients treated for HL following radiotherapy with or without anthracycline-containing chemotherapy. Our results enable estimation of HF risk for patients before treatment, during radiotherapy planning, and during follow-up

Cardiovascular Disease in Testicular Cancer Survivors:Identification of Risk Factors and Impact on Quality of Life

PURPOSE: Testicular cancer (TC) treatment is clearly associated with cardiovascular morbidity and mortality. To enable development of preventive strategies for cardiovascular disease (CVD), we assessed cardiometabolic risk factors and quality of life (QoL) in TC survivors.METHODS: Incidence of coronary artery disease, myocardial infarction, and heart failure after TC treatment was assessed in a multicenter cohort comprising 4,748 patients treated at the age of 12-50 years between 1976 and 2007. Patients who had developed CVD and a random sample from the cohort (subcohort) received a questionnaire on cardiometabolic risk factors and QoL. A subgroup of responders in the subcohort additionally underwent clinical evaluation of cardiovascular risk factors.RESULTS: After a median follow-up of 16 years, 272 patients had developed CVD. Compared with orchidectomy only, cisplatin combination chemotherapy was associated with an increased CVD risk (hazard ratio [HR], 1.9; 95% CI, 1.1 to 3.1). Patients who were obese or a smoker at diagnosis (HR, 4.6; 95% CI, 2.0 to 10.0 and HR, 1.7; 95% CI, 1.1 to 2.4, respectively), developed Raynaud's phenomenon (HR, 1.9; 95% CI, 1.1 to 3.6) or dyslipidemia (HR, 2.8; 95% CI, 1.6 to 4.7) or had a positive family history for CVD (HR, 2.9; 95% CI, 1.7 to 4.9) had higher CVD risk. More TC survivors with CVD reported inferior QoL on physical domains than survivors who did not develop CVD. Of 304 TC survivors who underwent clinical evaluation for cardiovascular risk factors (median age at assessment: 51 years), 86% had dyslipidemia, 50% had hypertension, and 35% had metabolic syndrome, irrespective of treatment.CONCLUSION: Cardiovascular events in TC survivors impair QoL. Many TC survivors have undetected cardiovascular risk factors. We advocate early lifestyle adjustments and lifelong follow-up with low-threshold treatment of cardiovascular risk factors, especially in obese and smoking patients treated with platinum-based chemotherapy.</p

Risk of breast cancer in women after a salivary gland carcinoma or pleomorphic adenoma in the Netherlands

Salivary and mammary gland tumors show morphological similarities and share various characteristics, including frequent overexpression of hormone receptors and female preponderance. Although this may suggest a common etiology, it remains unclear whether patients with a salivary gland tumor carry an increased risk of breast cancer (BC). Our purpose was to determine the risk of BC in women diagnosed with salivary gland carcinoma (SGC) or pleomorphic adenoma (SGPA). BC incidence (invasive and in situ) was assessed in two nationwide cohorts: one comprising 1567 women diagnosed with SGC and one with 2083 women with SGPA. BC incidence was compared with general population rates using standardized incidence ratio (SIR). BC risk was assessed according to age at SGC/SGPA diagnosis, follow-up time and (for SGC patients) histological subtype. The mean follow-up was 7.0 years after SGC and 9.9 after SGPA diagnosis. During follow-up, 52 patients with SGC and 74 patients with SGPA developed BC. The median time to BC was 6 years after SGC and 7 after SGPA. The cumulative risk at 10 years of follow-up was 3.1% after SGC and 3.5% after SGPA (95% Confidence Interval (95%CI) 2.1%-4.7% and 2.6%-4.6%, respectively). BC incidence was 1.59 times (95%CI 1.19-2.09) higher in the SGC-cohort than expected based on incidence rates in the general population. SGPA-patients showed a 1.48 times (95%CI 1.16-1.86) higher incidence. Women with SGC or SGPA have a slightly increased risk of BC. The magnitude of risk justifies raising awareness, but is no reason for BC screening

Myocardial dysfunction in long-term breast cancer survivors treated at ages 40-50years

AimsAnthracyclines increase heart failure (HF) risk, but the long-term prevalence of myocardial dysfunction in young breast cancer (BC) survivors is unknown. Early measures of left ventricular myocardial dysfunction are needed to identify BC patients at risk of symptomatic HF. Methods and resultsWithin an established cohort, we studied markers for myocardial dysfunction among 569 women, who were 5-7years (n = 277) or 10-12years (n = 292) after BC treatment at ages 40-50years. Left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) were assessed by echocardiography. N-terminal pro-brain natriuretic peptide (NT-proBNP) was measured in serum. Associations between patient-related and treatment-related risk factors and myocardial dysfunction were evaluated using linear and logistic regression. Median ages at BC diagnosis and cardiac assessment were 46.7 and 55.5years, respectively. Anthracycline-treated patients (n = 313), compared to the no-anthracycline group (n = 256), more often had decreased LVEF (10% vs. 4%), impaired GLS (34% vs. 27%) and elevated NT-proBNP (23% vs. 8%). GLS and LVEF declined in a linear fashion with increasing cumulative anthracycline dose (GLS: +0.23 and LVEF: -0.40 per cycle of 60mg/m(2); P125ng/L was highest for patients who received 241-300mg/m(2) anthracycline dose compared to the no-anthracycline group (odds ratio: 3.30, 95% confidence interval: 1.83-5.96). ConclusionImpaired GLS and increased NT-proBNP levels are present in a substantial proportion of young BC survivors treated with anthracyclines. Whether this will lead to future cardiac disease needs to be evaluated by longitudinal assessment
