Differences in Treatment and Outcome of Pancreatic Adenocarcinoma Stage I and II in the EURECCA Pancreas Consortium.

BACKGROUND: The EUropean REgistration of Cancer CAre (EURECCA) consortium aims to investigate differences in treatment and to improve cancer care through Europe. The purpose of this study was to compare neo- and adjuvant chemotherapy (ACT) and outcome after tumor resection for pancreatic adenocarcinoma stage I and II in the EURECCA Pancreas consortium. METHODS: The eight, collaborating national, regional, and single-center partners shared their anonymized dataset. Patients diagnosed in 2012-2013 who underwent tumor resection for pancreatic adenocarcinoma stage I and II were investigated with respect to treatment and survival and compared using uni- and multivariable logistic and Cox regression analyses. All comparisons were performed separately per registry type: national, regional, and single-center registries. RESULTS: In total, 2052 patients were included. Stage II was present in the majority of patients. The use of neo-ACT was limited in most registries (range 2.8-15.5%) and was only different between Belgium and The Netherlands after adjustment for potential confounders. The use of ACT was different between the registries (range 40.5-70.0%), even after adjustment for potential confounders. Ninety-day mortality was also different between the registries (range 0.9-13.6%). In multivariable analyses for overall survival, differences were observed between the national and regional registries. Furthermore, patients in ascending age groups and patients with stage II showed a significant worse overall survival. CONCLUSIONS: This study provides a clear insight in clinical practice in the EURECCA Pancreas consortium. The differences observed in (neo-)ACT and outcome give us the chance to further investigate the best practices and improve outcome of pancreatic adenocarcinoma.

Advances in rectal cancer: Real-world evidence suggests limited gains in prognosis for elderly patients.

BACKGROUND: Rectal cancer treatment has improved considerably due to the introduction of total meso-rectal excision, radio-chemotherapy, and high-resolution imaging. The aim of this observational cohort study was to quantify the effectiveness of these advances using high-quality data from a representative cohort of patients. METHODS: 20 281 non-metastasized cases retrieved from the Munich Cancer Registry database were divided into three time periods corresponding to before (1988-1997), partial (1998-2007), and full implementation (2008-2019) of clinical advances. Early-onset (<50 yrs.), middle-aged, elderly patient subgroups (> 70 yrs.) were compared. The overall effectiveness of evidence-based guideline adherence was also examined. RESULTS: Median survival improved by 1.5 yrs. from the first to the last time period. Relative survival increased from 74.9% (5-yr 95%CI[73.3 - 76.6]) to 79.2% (95%CI[77.8 - 80.5]). The incidence of locoregional recurrences was reduced dramatically by more than half (5-yr 17.7% (95%CI[16.5 - 18.8]); 6.7% (95%CI[6.1 - 7.3])). Gains in 5-yr relative survival were limited to early-onset and middle-aged patients with no significant improvement seen in elderly patients (Female 68.6% [63.9 - 73.3] to 67.6% [64.0 - 71.2]; Male 71.7% [65.9 - 77.4] to 74.0% [70.8 - 77.2]). CONCLUSIONS: Real-world evidence suggests that recent treatment advances have lead to an increase in prognosis for rectal cancer patients. However, more effort should be made to improve the implementation of new developments in elderly patients. Especially considering, that these cases represent a growing majority of diagnosed patients.

Quality of life in localised malignant melanoma.

BACKGROUND: The incidence of melanoma is still increasing in fair-skinned populations. At least 80% of patients have localised disease and expect a 5-year relative survival of >90%. PATIENTS AND METHODS: In 2003-2004, disease-free patients with localised melanoma were recruited from the Munich Cancer Registry to answer quality-of-life (QoL) questionnaires 2 years after treatment. RESULTS: A response rate of 72% was achieved from a total of 1085 distributed questionnaires. Hundred and seventeen questionnaires had to be excluded because of updated information about secondary tumour and progression events. Thus, questionnaires from 664 patients were evaluated. QoL scores in melanoma patients were essentially similar to those of a general population. Differences were detected between women and men concerning emotional and sexual functioning. Age and number of comorbidities were the strongest factors influencing most all aspects of QoL. Fifty percent of patients referred to deficits in communication with their doctors. CONCLUSIONS: Patients who overcome melanoma do not necessarily have a reduced QoL. Strategies used by these melanoma patients resulted in similar levels of coping as previous studies in comparable general populations. Nevertheless, doctor-patient communication was correlated with emotional and social functioning and should be emphasised in treatment and care of melanoma patients.

Trends in surgery and outcomes of squamous cell vulvar cancer patients over a 16-year period (1998-2013): a population-based analysis.

PURPOSE: The objective was to identify trends in surgery and the outcomes of squamous cell vulvar cancer in a population-based setting. METHODS: A total of 1113 patients with squamous cell vulvar cancer diagnosed between 1998 and 2013 in the catchment area of the Munich Cancer Registry (population approximately 4.6 million) were analysed. Trends in prognostic factors and treatment were examined by comparing patients diagnosed between 1998 and 2008 with those diagnosed between 2009 and 2013. Cumulative incidence was used to calculate time to local (LR) and lymph node recurrence (LNR). Survival was analysed by the Kaplan-Meier method, calculation of relative survival (RS), and a Cox model. RESULTS: The high median age at diagnosis of 75 years did not change significantly over time. In addition, no changes in the subsite of tumour or grading were noted. A decrease in patients undergoing complete vulvectomy from 27.7 to 17.8 % (p < 0.001) as well as an increase in the use of sentinel lymph node biopsy from 11.4 to 39.1 % (p < 0.001) was observed. However, time to LR (from 19 to 19 %) and time to LNR (from 9 to 9 %) as well as 5-year overall survival (from 55 to 55 %) and RS (from 66 to 63 %) were not significantly altered. After adjustment for prognostic factors, less radical locoregional surgery had no influence on survival. CONCLUSION: Less radical locoregional surgery in vulvar cancer is increasingly implemented. Locoregional recurrence and survival have not been affected by these changes and are likely accompanied by an improvement in quality of life.

Prospective documentation and analysis of the pre- and early clinical management in severe head injury in southern Bavaria at a population based level.

Treatment of patients suffering from severe head injury is so far restricted to general procedures, whereas specific pharmacological agents of neuroprotection including hypothermia have not been found to improve the outcome in clinical trials. Albeit effective, symptomatic measures of the preclinical rescue of patients (i.e. stabilization or reestablishment of the circulatory and respiratory system) or of the early clinical care (e.g. prompt diagnosis and treatment of an intracranial space occupying mass, maintenance of a competent circulatory and respiratory system, and others) by and large constitute the current treatment based on considerable organizational and logistical efforts. These and other components of the head injury treatment are certainly worthwhile of a systematic analysis as to their efficacy or remaining deficiencies, respectively. Deficits could be associated with delays of providing preclinical rescue procedures (e.g. until intubation of the patient or administration of fluid). Delays could also be associated in the hospital with the diagnostic establishment of intracranial lesions requiring prompt neurosurgical intervention. By support of the Federal Ministry of Education and Research and under the auspices of the Forschungsverbund Neurotraumatology, University of Munich, a prospective system analysis was carried out on major aspects of the pre- and early clinical management at a population based level in patients with traumatic brain injury. Documentation of pertinent data was made from August 1998 to July 1999 covering a catchment area of Southern Bavaria (5.6 mio inhabitants). Altogether 528 cases identified to suffer from severe head injury (GCS < or = 8 or deteriorating to that level within 48 hrs) were enrolled following admission to the hospital and establishment of the diagnosis. Further, patients dying on the scene or during transport to the hospital were also documented, particularly as to the frequency of severe head injury as underlying cause of mortality. The analysis included also cases with additional peripheral trauma (polytrauma). The efficacy of the logistics and organization of the management was studied by documentation of prognosis-relevant time intervals, as for example until arrival of the rescue squad at the scene of an accident, until intubation and administration of fluid, or upon hospital admission until establishment of the CT-diagnosis and commencement of surgery or transfer to the intensive care unit, respectively. The severity of cases studied in the present analysis is evident from a mortality of far above 40% of cases admitted to the hospital, which was increased by about 20% when including prehospital mortality. The outcome data notwithstanding, the emerging results demonstrate a high efficacy of the pre- and early clinical management, as indicated by a prompt arrival of the rescue squad at the scene, a competent prehospital and early clinical management and care, indicative of a low rate of avoidable complications. It is tentatively concluded on the basis of these findings that the patient prognosis is increasingly determined by the manifestations of primary brain damage vs. the development of secondary complications.

Communication, quality of life and age: results of a 5-year prospective study in breast cancer patients.

BACKGROUND: Previous studies have employed short follow-up periods or examined only certain aspects of quality of life (QoL). This study aimed to examine the effect of communication on breast cancer patients' QoL and to investigate the role of age in this relationship. PATIENTS AND METHODS: In a prospective, observational study breast cancer patients were sent questionnaires, including the European Organisation for Research and Treatment of Cancer QLQ-C30, over 5 years. RESULTS: Forty-five per cent of the sample reported that some aspect of the communication they received was unclear and 59% wanted to speak with medical staff more. Patients under 50 years rated social and psychological help as more important, they were more aware of such services, had greater contact with support groups but were less satisfied with the information they received. Seventeen of the 27 QoL variables were significantly worse (P <0.01), up to 4 years after diagnosis, for those patients reporting unclear information. For patients over 50 years, QoL was significantly (P <0.001) worse when communication was unsatisfactory. Operation method or arm problems did not mitigate the association between communication and QoL. CONCLUSIONS: Communication is clearly a vital clinical skill that may play a role in patient QoL.

Comparison of breast and rectal cancer patients' quality of life: results of a four year prospective field study.

This paper compares quality of life in breast and rectal cancer patients. The Munich Cancer Registry records clinical details of all cancer patients in the region. Over a 2-year period, cooperating clinicians recruited patients who were sent quality of life questionnaires, including the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - C30 over 4 years. Breast cancer patients were compared to both male and female rectal cancer patients. A total of 1315 patients returned questionnaires (988 breast cancer, 327 rectal cancer). More breast cancer patients were under 70 years old, received adjuvant therapy, had a good prognosis, took medication and rated psychological support as important. Breast cancer patients reported poorer quality of life than rectal cancer patients in more than half the variables. In particular, they suffered significantly worse emotional functioning, fatigue, pain and sleeplessness. Female rectal cancer patients did not suffer the same problems. Both age groups and those with or without adjuvant therapy indicated the same trend, with breast cancer patients reporting lower scores. Breast cancer patients, despite better prognoses, appear to suffer more psychological problems than rectal cancer patients. Gender, age and therapy did not seem to explain these differences. The negative public perception of breast cancer may play a role.

[Nosocomial infections in head and neck surgery. 2. A prospective study]. / Nosokomiale Infektionen in der Kopf- und Halschirurgie. Teil 2: Eine prospektive Untersuchung.

Nosocomial infections are defined as infections that occur during hospitalization but were not present at admission. Nosocomial infections have been found to occur in 6% of all hospitalizations and are present mainly in intensive care units and surgical wards. These infections extend the time of hospitalization and therefore increase the cost of care. Between July and December 1993, all nosocomial infections occurring in 304 patients of the surgical ward of the University ENT Department, Cologne, were recorded prospectively. These were classified into wound, implant, urinary tract, respiratory, skin or mucosal infections, nosocomial bacteremias and gastrointestinal infections. The overall prevalence of nosocomial infections was 15.4%. Of these, 9.2% were postoperative wound infections, 2.6% respiratory infections, and 2.3% infections of the skin and mucosa. The incidence of urinary tract infections was 0.7%, while bacteremias occurred in 0.3%. No implant or gastrointestinal infections occurred. Microbial analysis demonstrated 9 gram-positive and 15 gram-negative bacterial and 8 candidal infections. Nineteen cultures were negative. Among the bacteria cultured three were methicillin-resistant. The time of hospitalization was extended from a normal average of 9.52 days to 25.7 days. The distinct risk of a nosocomial infection in the treatment of hospitalized patients requires and accurate documentation of all acquired infections. Determination of the source of infection, the method of spread and microbial analysis including the spectrum of organism resistance is necessary in order to decrease the infection rate and to prevent establishment of a nosocomial infection. These requirements at the least are an important part of quality control in the surgical disciplines.
