TLDR
The hypofractionation regimen did not result in a significant reduction in BCDF; however, it is delivered in 2.5 fewer weeks; men with compromised urinary function before treatment may not be ideal candidates for this approach.
Abstract
Purpose To determine if escalated radiation dose using hypofractionation significantly reduces biochemical and/or clinical disease failure (BCDF) in men treated primarily for prostate cancer. Patients and Methods Between June 2002 and May 2006, men with favorable- to high-risk prostate cancer were randomly allocated to receive 76 Gy in 38 fractions at 2.0 Gy per fraction (conventional fractionation intensity-modulated radiation therapy [CIMRT]) versus 70.2 Gy in 26 fractions at 2.7 Gy per fraction (hypofractionated IMRT [HIMRT]); the latter was estimated to be equivalent to 84.4 Gy in 2.0 Gy fractions. High-risk patients received long-term androgen deprivation therapy (ADT), and some intermediate-risk patients received short-term ADT. The primary end point was the cumulative incidence of BCDF. Secondarily, toxicity was assessed. Results There were 303 assessable patients with a median follow-up of 68.4 months. No significant differences were seen between the treatment arms in terms of the distribution of ...

Guidelines on Prostate Cancer

TL;DR: The introduction of an effective blood test, prostate specific antigen (PSA), has made it possible to diagnose more and more men in an earlier stage where they can be offered potentially curative treatments, and this is the subject of the EAU guidelines on prostate cancer.

Nonparametric Estimation from Incomplete Observations

TL;DR: In this article, the product-limit (PL) estimator was proposed to estimate the proportion of items in the population whose lifetimes would exceed t (in the absence of such losses), without making any assumption about the form of the function P(t).

A Proportional Hazards Model for the Subdistribution of a Competing Risk

TL;DR: This article proposes methods for combining estimates of the cause-specific hazard functions under the proportional hazards formulation, but these methods do not allow the analyst to directly assess the effect of a covariate on the marginal probability function.

A Class of $K$-Sample Tests for Comparing the Cumulative Incidence of a Competing Risk

Robert Gray
- 01 Jan 1988 - 
TL;DR: In this paper, a class of tests developed for comparing the cumulative incidence of a particular type of failure among different groups is presented. The tests are based on comparing weighted averages of the hazards of the subdistribution for the failure type of interest.

TL;DR: The AUA symptom index for benign prostatic hyperplasia was developed and validated by a multidisciplinary measurement committee of the American Urological Association and is clinically sensible, reliable, valid and responsive.
