[Reflexions on techniques of preoperative radiotherapy in the treatment of carcinoma of the bladder. Initial results and discussion of a therapeutic protocol based upon histo-prognosis (author's transl)].

Basing their indications on the histo-prognosis of Opperman and Bittard in malignant tumours of the bladder, the authors decided to irradiate before cystectomy those bladder tumours in which the histo-prognostic index indicated that it was a local disease with metastatic potential with a spontaneous life expectancy of 18 to 30 months. Radiotherapy was given spread over 23 or 27 fractions providing a total of 46 Gy. Four to 6 weeks later, cystoprostatectomy with trans-ileal cutaneous ureterostomy was performed, before chemotherapy for one year.

[Paraganglioma of the organs of Zuckerkandl. A case report (author's transl)].

Endocrine manifestations were absent in a patient presenting with pain in the left peri-umbilical region from a paraganglioma of the organs of Zuckerkandl. The authors describe the embryology of paragangliomas and review the published literature concerning the noradrenaline-secreting forms of these tumors. Only 86 references to those of Zuckerkandl, situated on the side of the aorta in relation to the inferior mesenteric artery, were found.
