PURPOSE To estimate actual utilization rates of radiation therapy (RT) in Norway, describe time trends (1997-2010), and compare these estimates with corresponding optimal RT rates. METHODS AND MATERIALS Data from the population-based Cancer Registry of Norway was used to identify all patients diagnosed with cancer and/or treated by RT for cancer in(More)
BACKGROUND The Norwegian Rectal Cancer Project was initated in 1993 with the aims of improving surgery, decreasing local recurrence rates, improving survival, and establishing a national rectal cancer registry. Here we present results from the Norwegian Colorectal Cancer Registry (NCCR) from 1993 to 2010. MATERIAL AND METHODS A total of 15 193 patients(More)
BACKGROUND Treatment of early stage rectal cancer has excellent oncological results. To reduce treatment-related mortality and morbidity and improve functional results, a focus on local resections is increasingly important. OBJECTIVE The purpose of this study was to compare outcomes after transanal endoscopic microsurgery and total mesorectal excision for(More)
BACKGROUND Population-based studies for gastric adenocarcinoma are scarce, particularly studies conducted within a defined geographical area with publicly available censuses that allow incidence rates to be calculated. MATERIAL AND METHODS Population-based study in Central Norway from 2001 to 2011, covering a population of 636 000-680 000, respectively.(More)
BACKGROUND AND PURPOSE Trials in rectal cancer have shown that radiotherapy (RT) decreases local recurrence rates, whereas the effects on survival are uncertain. Swedish and Norwegian oncologists have had different treatment recommendations. The aim was to evaluate local recurrence rates and survival in the two countries. PATIENTS AND METHODS Between 1995(More)
BACKGROUND In patients with prostate cancer (PCa), the lack of clear guidelines on the use of radiotherapy after radical prostatectomy (RP) invites unwanted variation of this treatment. We describe the hazard ratios and probabilities related to the use of post-RP radiotherapy. MATERIAL AND METHODS Data were collected from the Cancer Registry of Norway and(More)
OBJECTIVE Reports from cancer registries often lack clinically relevant information, which would be useful in estimating the prognosis of individual patients with urothelial carcinoma of the urinary bladder (UCB). This article presents estimates of crude probabilities of death due to UCB and the expected loss of lifetime stratified for patient(More)
BACKGROUND AND PURPOSE Preoperative (chemo)radiotherapy ((C)RT) for rectal cancer is, in Norway, restricted to patients with cT4-stage or threatened circumferential resection margin. This nationwide population-based study assessed the use of preoperative (C)RT in Norway and its impact on treatment outcomes. PATIENTS AND METHODS Data from The Norwegian(More)
BACKGROUND Medulloblastoma (MB) and supratentorial primitive neuroectodermal tumor of the central nervous system (CNS-PNET) are among the most common pediatric brain tumors. The diagnosis, treatment, and outcome of MB/CNS-PNET patients treated during the last four decades at Oslo University Hospital (OUH) are described. MATERIAL AND METHODS All patients(More)
BACKGROUND Long-term relative survival (RS) data for testicular germ cell tumor (TGCT) patients are scarce. We aimed to analyze long-term RS among TGCT patients diagnosed in Norway, between 1953 and 2012. METHODS Data sources were the Cancer Registry of Norway and the Norwegian Cause of Death Registry. TGCT patients diagnosed during 1953 to 2012 were(More)
