Background. Esophagus and stomach cancers are associated with poor prognosis. But most published population-based cancer survival estimates for stomach and esophagus cancer refer to survival experience of patients diagnosed in the 1990s or earlier years. The aim of this study was to provide up-to-date survival estimates and trends for patients with stomach and esophagus cancer in Germany. Material and methods. Our analysis is based on data from 11 population-based cancer registries, covering 33 million inhabitants. Patients diagnosed with stomach and esophagus cancer in 19972006 were included. Period analysis was used to derive five-year relative survival estimates and trends by age, sex, cancer subsite, and stage for the time period of 20022006. German and US survival estimates were compared utilizing the SEER 13 database. Results. Overall age-standardized five-year relative survival was 31.8% and 18.3% for stomach and esophagus cancer, respectively, compared to 27.2% and 17.4% in the US. Survival was somewhat higher among female than among male patients for both cancer sites (33.6% vs. 30.6% and 21.5% vs. 17.5%, respectively) and much higher for non-cardia stomach cancer (40.4%) than for cardia cancer (23.4%). From 2002 to 2006, a moderate increase in five-year relative survival by 2.7 percent units was observed for non-cardia stomach cancer patients in Germany (p <0.001). Conclusion. Five-year relative cancer survival has reached levels around 40% for patients with non-cardia stomach cancer in Germany in the early 21st century, whereas it remained at lower levels around 20% for patients with esophagus and cardia cancer. © 2012 Informa Healthcare.

Background/Aims:Dietary composition has been shown to affect acid-base homeostasis and bone health in humans. We investigated the potential renal acid load (PRAL) and the estimated diet-dependent net acid load (net endogenous acid production, NEAP) in adult vegans and evaluated the relationships between NEAP, food groups and intake of bone health-related nutrients. Methods: The German Vegan Study (GVS) is a cross-sectional study. Data from healthy men (n = 67) and women (n = 87), aged 21-75 years, who fulfilled the study criteria (vegan diet for ≥1 year prior to study start; age ≥18 years, and no pregnancy/childbirth during the last 12 months) were included in the analysis. NEAP values were calculated from diet composition using two models: one based on the protein/potassium quotient and another taking into account an anthropometry-based loss of urinary organic anions. Results:Mean daily intakes of phosphorus, potassium, sodium, magnesium and vitamin C were above, and vitamin D and calcium below Dietary Reference Intake (DRI). Regardless of the model used, the diet in the GVS was characterized by a nearly neutral NEAP. A strong correlation was observed between the NEAP values of the two models (r s = 0.873, p < 0.001). Only the consumption of fruits decreased constantly across the increasing quartiles of NEAP. Conclusions: It can be hypothesized that vegan diets do not affect acid-base homeostasis. With respect to bone health, the significance of this finding needs further investigation. Copyright © 2011 S. Karger AG, Basel. Source

The purpose of the present study was to describe the survival of patients diagnosed with oral cavity cancer in Germany. The analyses relied on data from eleven population-based cancer registries in Germany covering a population of 33 million inhabitants. Patients with a diagnosis of oral cavity cancer (ICD-10: C00-06) between 1997 and 2006 are included. Period analysis for 2002-2006 was applied to estimate five-year age-standardized relative survival, taking into account patients' sex as well as grade and tumor stage. Overall five-year relative survival for oral cavity cancer patients was 54.6%. According to tumor localization, five-year survival was 86.5% for lip cancer, 48.1% for tongue cancer and 51.7% for other regions of the oral cavity. Differences in survival were identified with respect to age, sex, tumor grade and stage. The present study is the first to provide a comprehensive overview on survival of oral cavity cancer patients in Germany. © 2013 Listl et al. Source

Goals of work: Quality of life (Qol) represents a relevant end point in the clinical management of advanced ovarian cancer (AOC). However, there exist only a few specific instruments which have been designed for patients with ovarian cancer. The aim of this study was to develop a systematic checklist (Berlin Symptom Checklist Ovary (BSCL-O)) as an instrument of Qol for patients with AOC and to discriminate between the frequency and the importance of symptoms. Patients and methods: The main symptoms were identified in a phase I study via free interviews of five patients with ovarian cancer (OC) as well as five medical doctors, family dependants, and care workers. In the phase II study, the capability of BSCL-O was evaluated by questionnaire-guided interviews of 200 patients with primary OC, recurrent OC, metastasized breast cancer, and benign ovarian tumors. Main results: In phase I, 36 main symptoms were identified. In phase II, 7,200 answers from 98.5% of all patients were evaluable. Of the 36 symptoms of the BSCL-O, 23 revealed clinical relevance. There was a correlation of frequency and importance of symptoms (p<0.05). The symptoms of the BSCL-O were deemed twice as strenuous in patients with recurrent OC. Conclusions: The BSCL-O can measure Qol of patients with OC. The BSCL-O is being validated in a phase III study. © Springer-Verlag 2009. Source

Background: No agreement has been reached on the long-term survival prospects for patients with Cushing's disease. We studied life expectancy in patients who had received curative treatment and whose hypercortisolism remained in remission for more than 10 years, and identified factors determining their survival. Methods: We did a multicentre, multinational, retrospective cohort study using individual case records from specialist referral centres in the UK, Denmark, the Netherlands, and New Zealand. Inclusion criteria for participants, who had all been in studies reported previously in peer-reviewed publications, were diagnosis and treatment of Cushing's disease, being cured of hypercortisolism for a minimum of 10 years at study entry, and continuing to be cured with no relapses until the database was frozen or death. We identified the number and type of treatments used to achieve cure, and used mortality as our primary endpoint. We compared mortality rates between patients with Cushing's disease and the general population, and expressed them as standardised mortality ratios (SMRs). We analysed survival data with multivariate analysis (Cox regression) with no corrections for multiple testing. Findings: The census dates on which the data were frozen ranged from Dec 31, 2009, to Dec 1, 2014. We obtained data for 320 patients with 3790 person-years of follow-up from 10 years after cure (female:male ratio of 3:1). The median patient follow-up was 11·8 years (IQR 17-26) from study entry and did not differ between countries. There were no significant differences in demographic characteristics, duration of follow-up, comorbidities, treatment number, or type of treatment between women and men, so we pooled data from both sexes for survival analysis. 51 (16%) of the cohort died during follow-up from study entry (10 years after cure). Median survival from study entry was similar for women (31 years; IQR 19-38) and men (28 years; 24-42), and about 40 years (IQR 30-48) from remission. The overall SMR for all-cause mortality was 1·61 (95% CI 1·23-2·12; p=0·0001). The SMR for circulatory disease was increased at 2·72 (1·88-3·95; p<0·0001), but deaths from cancer were not higher than expected (0·79, 0·41-1·51). Presence of diabetes, but not hypertension, was an independent risk factor for mortality (hazard ratio 2·82, 95% CI 1·29-6·17; p=0·0095). We noted a step-wise reduction in survival with increasing number of treatments. Patients cured by pituitary surgery alone had long-term survival similar to that of the general population (SMR 0·95, 95% CI 0·58-1·55) compared with those who were not (2·53, 1·82-3·53; p<0·0001). Interpretation: Patients with Cushing's disease who have been in remission for more than 10 years are at increased risk of overall mortality compared with the general population, particularly from circulatory disease. However, median survival from cure is excellent at about 40 years of remission. Treatment complexity and an increased number of treatments, reflecting disease that is more difficult to control, appears to negatively affect survival. Pituitary surgery alone is the preferred treatment to secure an optimum outcome, and should be done in a centre of surgical excellence. Funding: None. © 2016 Elsevier Ltd. Source
