[Locoregional recurrent rectal cancer: the place of radiotherapy].

Currently, locoregional recurrence of rectal cancer is rare due to the therapeutic progress of total mesorectal excision and pre-operative radiotherapy. Nevertheless, a curative treatment could be proposed provided that surgical removal is possible and complete. Here, we will discuss the position of both external and intra-operative radiotherapy, and concomitant chemotherapy.

[Cancer of the rectum: target volumes for preoperative radiotherapy].

Preoperative radiotherapy is the standard treatment for locally advanced resectable rectal adenocarcinoma. The total mesorectal excision leads to a dramatic increase of local control rate. Thus, the mesorectal space is the usual field for the spread of rectal cancers cells.

[Percutaneous absorption of metallic cations: uranium particulates].

Washing is usually used to reduce the risk of a skin contamination. Skin biopsies were used and contaminations were realised with 1) soluble radioactive calcium 2) insoluble particles of uranium. The result obtained with different wash liquids are presented here.
