Re-irradiation for recurrent rectal cancer - a single-center experience.

There is no clear consensus on the use of re-irradiation (reRT) in the management of locally recurrent rectal cancer (LRRC). The aim of the present study was to investigate all reRT administered for rectal cancer at a large referral institution and to evaluate patient outcomes and toxicity. All patients with rectal cancer were identified who had received previous pelvic radiotherapy (RT) and underwent reRT during 2006-2016.

Waiting times and treatment following cancer diagnosis: comparison between immigrants and the Norwegian host population.

There are concerns about timely access to appropriate cancer treatment for the growing immigrant population in Norway. This study aims to compare waiting times between cancer diagnosis and start of cancer treatment, as well as treatment patterns between immigrants in Norway and the host population. We performed a nationwide, registry-based study with individual-level data, including 213,320 Norwegians and 8324 immigrants diagnosed with breast, colorectal, lung or prostate cancer in 1990-2014.

Factors influencing access to palliative radiotherapy: a Norwegian population-based study.

Background: Palliative radiotherapy (PRT) comprises half of all radiotherapy use and is an effective and important treatment modality for improving quality of life in incurable cancer patients. We have described the use of PRT in Norway and aimed to identify and quantify the impact of factors associated with PRT utilization.

Material And Methods: Population-based data from the Cancer Registry of Norway identified 25,281 patients who died of cancer, 1 July 2009-31 December 2011.

Preoperative chemoradiotherapy for rectal cancer and impact on outcomes - A population-based study.

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 Colorectal Cancer Registry were used to identify all stage I-III rectal cancers treated with major resection (1997-2011: n=9193).

Utilization of radiation therapy in Norway after the implementation of the national cancer plan--a national, population-based study.

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 1997-2010. Radiation therapy utilization rates (RURs) were calculated as (1) the proportion of incident cancer cases who received RT at least once within 1 year of diagnosis (RUR1Y); and (2) the proportion who received RT within 5 years of diagnosis (RUR5Y).
