The legal recognition of autopsy as a tool of quality assurance will strengthen its importance especially in the care of cancer patients. However, this confidence is relativized by the consideration of the assessment of the autopsy in various effective nonlegislative regulations. This consideration shows that in contrast to earlier years autopsy does not play a major role in the most important programs for the certification of cancer centers or for clinical cancer registration.

Purpose: The 70-year threshold determines whether patients are eligible or not for the breast cancer screening program in Germany. It is not known whether this age threshold also influences the choice of adjuvant treatment and ultimate outcome.

Methods: 3463 patients were analyzed from the clinical cancer registry Regensburg (Germany) with primary, non-metastatic invasive breast cancer diagnosed between 2000 and 2012.

Following the adoption of the Cancer Screening and Registry Act (KFRG) to advance the development of the early detection of cancer and to promote quality assurance through Clinical Cancer Registries according to Sect. 65c SGB V, the question is raised as to what extent population-based clinical cancer registries may contribute not only to direct patient treatment benefits, but also to the requirements of health research and to other issues such as, for example, the evaluation of the benefit of new pharmaceutical products. Efforts to improve a nationwide quality management for oncology have so far not been successful in the development of comprehensive documentation at all levels of care.

Background: Medical treatment in patient-centred care in oncology is broadly managed and regulated in terms of guideline development, cancer centres, and quality assurance by cancer registries. In contrast to this quality management cycle (PDCA), there are no equal standards for patient-reported outcomes like quality of life (QoL). Therefore, the Tumour Centre Regensburg e.

Purpose: To determine whether the immunohistochemical markers survivin and E-cadherin can predict progress at initially diagnosed Ta bladder cancer.

Methods: We retrospectively searched for every initially diagnosed pTa urothelial bladder carcinoma having been treated at our single-center hospital in Germany from January 1992 up to December 2004. Follow-up was recorded up to June 2010, with recurrence or progress being the endpoints.

The aim of the present study was to evaluate to what extent the combination of standard histopathological parameters determines the biology of breast cancer and the effect on therapy and prognosis. The Clinical Cancer Registry Regensburg (Bavaria, Germany) included n = 4,480 female patients with primary, non-metastatic (M0) invasive breast cancer diagnosed between 2000 and 2012. Immuno-histochemical analyses, i.

Purpose: Adjuvant endocrine therapy (ET) is indicated in patients with steroid hormone receptor (HR)-positive breast cancer. The aim of this study was to evaluate the quality of HR determination and adjuvant endocrine treatment of breast cancer patients in a large cohort of more than 7000 women by analyzing data from a population-based regional cancer registry.

Methods: Data from the Clinical Cancer Registry Regensburg (Bavaria, Germany) were analyzed.

Background And Purpose: Positive surgical margins (PSM) after radical prostatectomy have been shown to be associated with impaired outcome. In pT3pN0 patients with PSM either immediate radiotherapy or clinical and biological monitoring followed by salvage radiotherapy is recommended by the latest guidelines of the European Association of Urology.

Materials And Methods: A retrospective, multicenter study of eight urological centers was conducted on 536 prostatectomy patients with pT3aN0/NxR1 tumors and no neoadjuvant/adjuvant therapy.

Background: Colorectal cancer is the third most common cancer and a major cause of morbidity and mortality worldwide. Adjuvant chemotherapy is considered the standard of care in patients with UICC stage III colon cancer after R0 resection. Adjuvant therapy was not shown to be beneficial in patients with UICC stage II colon cancer.

Background & Aims: Early detection of neoplastic lesions is essential in patients with long-standing ulcerative colitis but the best technique of colonoscopy still is controversial.

Methods: We performed a prospective multicenter study in patients with long-standing ulcerative colitis. Two colonoscopies were performed in each patient within 3 weeks to 3 months.

Purpose: Radical cystectomy (RC) can be associated with significant blood loss, whereas many patients are presenting with anemia preoperatively. To date, there is a lack of data addressing the impact of preoperative anemia (PA) on survival of patients undergoing RC for urothelial carcinoma of the bladder (UCB).

Methods: This retrospective multicenter study includes 684 patients with UCB undergoing RC with pelvic lymph node dissection.

Purpose: To predict biochemical recurrence respecting the natural course of pT2 prostate cancer with positive surgical margin (R1) and no adjuvant/neoadjuvant therapy.

Methods: A multicenter data analysis of 956 patients with pT2R1N0/Nx tumors was performed. Patients underwent radical prostatectomy between 1994 and 2009.

Compared to other members of the fibroblast growth factor receptor (FGFR) family, only few studies investigate FGFR3 in tumour angiogenesis. We investigated the connection between angiogenesis and FGF/FGFR expression including FGFR3 mutation status in urothelial carcinomas. Immunohistochemistry was performed in invasive and non-invasive urothelial cancers of 61 patients.

Objective: Outcome prediction of pT3 urothelial carcinoma of the bladder (UCB) after radical cystectomy (RC) remains challenging. The objective of our study was to determine high-risk patients with poor survival outcome in a heterogeneous group substaged pT3 who might profit from early adjuvant chemotherapy.

Materials And Methods: We compiled clinicopathological and immunohistochemical data of E-cadherin (E-cad) expression in 116 patients with pT3 UCB after RC in our single-center series.

Even though randomized controlled clinical trials demonstrated improved survival by adjuvant trastuzumab treatment of HER2-positive breast cancer patients, data on its effect in clinical routine are scarce. This study evaluated the use and efficacy of trastuzumab in routine treatment of HER2-positive breast cancer patients. Data from the clinical cancer registry Regensburg (Germany) were analyzed.

The law for the development of early cancer detection and quality assurance by clinical cancer registries regulates the duties, the funding, and the functions of the clinical cancer registries and thereby the cooperation between epidemiological and clinical registries. The necessary regulations and interfaces are described here. The progress in new concepts of cancer registration is triggered by fundamental changes in oncological care such as the increasing use of high-quality guidelines and the certification of oncological health-care units.

In this study, we determined the genotype distribution of two single nucleotide polymorphisms (SNPs) in secreted frizzled related protein 1 (SFRP1), rs3242 and rs921142, in a Caucasian bladder cancer case-control study. Allelic variants of the SNPs were determined using restriction fragment length polymorphism (RFLP) analysis and partly verified by sequencing analysis. Overall, DNA from 188 consecutive and 215 early-onset bladder cancer patients (≤45 years) as well as from 332 controls was investigated.

Purpose: To study the expression, localization and potential clinical significance of aquaporin water channels both in well-established urothelial cancer (UC) cell lines and in human bladder carcinoma specimens of different stages and grades and to discuss the clinical relevance of the findings.

Methods: AQP transcript and protein expression by RT4, RT112 and T24 UC cell lines was investigated using reverse transcriptase polymerase chain reaction and immunofluorescence labelling. Immunohistochemistry (IHC) was used to assess AQP protein expression in 94 UC specimens of various grades and stages.

Background: Biomarkers could help to estimate the prognosis of solid tumors. One of the reasons that many immunohistochemical (IHC) markers are not used routinely is the high interobserver variability and various cutoff values. In the present study, we used a simplified IHC method with a group of 8 biomarkers in stage pT1 urothelial bladder carcinoma (UBC).
