Maximizing rectal dose sparing with hydrogel: A retrospective planning study

The effect of Rectal Retractor, a rectal protector on rectal dose in radical prostate radiotherapy

Introduction: The close proximity of the rectum tissue to the prostate gland results in rectal toxicity during prostate radiotherapy. Rectal Retractor (RR) is a rectal displacement technique that inserts into the rectum, as a result, the lateral and dorsal part of the rectal wall push away from high dose areas. The aim of this study was to investigate the dosimetric consequence...

VMAT planning study in rectal cancer patients

BACKGROUND To compare the dosimetric differences among fixed field intensity-modulated radiation therapy (IMRT), single-arc volumetric-modulated arc therapy (SA-VMAT) and double-arc volumetric-modulated arc therapy (DA-VMAT) plans in rectal cancer. METHOD Fifteen patients with rectal cancer previously treated with IMRT in our institution were selected for this study. For each patient, three p...

Rectal paracetamol has a significant morphine-sparing effect after hysterectomy.

We have evaluated the morphine-sparing effect of rectal paracetamol during the first 24 h after abdominal hysterectomy in a placebo-controlled, double-blind study. We studied 72 patients receiving patient-controlled analgesia (PCA) with i.v. morphine after a standardized anaesthetic, allocated randomly to receive rectal paracetamol 1.3 g, diclofenac 50 mg or placebo, after wound closure and at ...
