They use fine disposable plastic tubes fitted with mandril, which allow loading of light radioactive material in any case. Short term results are discussed according to 101 applications.

This treatment, however, which is only localized to the mediastinum, has not prevented the appearance of metastases at a later date. It is obvious, therefore, that though we have improved local prognosis by localized and regional treatment, and the association of radiotherapy and surgery, we have not been able to act on the residual cancerous disease, and something else is needed. This "something else" must be chemotherapy, but at the present time we do not know which product, at which dose, and at which moment, this chemotherapy should be applied to be most effective.

A great interest has been stimulated for the treatment of the tumors by hyperthermia alone or associated to chemo and radiotherapy. The clinical application needs an accurate control of the temperature which raises difficult technical problems.

Three investigations are considered and compared : Dimer X radiculography, lumbar phlebography, duroliopaque myelography. The transfemoral arcending lumbar catheterization of the epidural veins precise the compression by staphylococcic external pachymeningitis. No liquid is introduced in cerebro spinal fluid : there is not risk of infectious arachnoiditis. Myelography with positive contrast (duroliopaque: ethyl monoiodostearate) is much attractive but it is a procedure not easy to perform, even badly tolerated by the patient. For these reasons the lumbar phlebography, easily performed, can be realised in first intention.

Two varieties can be distinguished : one with a well-defined enlarged medial image, and a more limited type which is often anterior, at the fibrous ring level and in contact with the vertebral plates. The latter is seen less frequently, but needs to be considered, as it precedes the changes seen in the nucleus pulposus in the intersomatic alteration. It has been shown that this image is of gaseous origin. It is caused by the liberation of gas into a newly-formed intersomatic cavity situated either in the nucleus pulposus or fibrous ring levels. The vacuum-disc phenomenon is of great diagnostic value as it is usually found in relation to degenerated discs and permits orientation of diagnosis towards classical arthrosis or Pott's pseudo-arthrosis when atypical radiological images are seen.

The radiological appearance is characteristic, with more or less widespread, but shallow, extrinsic prints with irregular contours typical of malignant tumours. Its gastric origin is strongly suggested by its position of the superior border of the transverse colon. The authors report 6 observations in which the value of this very characteristic radiological abnormality of the colon to diagnose primary stomach cancer was confirmed. Radiological appearances are not very specific in primary stomach cancer and interpretation is often difficult; endoscopy or even biopsies are often inconclusive.

The examination is begun in a seated position, in dorsal horizontal and trickling provides perfect conditions of study, selective and with no opaque superimposition, of the posterior surface of the stomach, the site of 90% of organic lesions. Study of the anterior surface is also simplified. Practically no patient cooperation is required and the technique may be used in the elderly and those with physical incapacity. The aim is to obtain a morphologically and physiologically pure picture of the mucosa and the gastric folds. Very small lesions may be visualised without resort to other techniques and the study of cases of gastritis is greatly simplified.

The diagnosis was made as an emergency by arteriography. 45 cases exist in the literature. Arteriography was performed in 10 cases. An arterio-canalar communication was demonstrated in only 3 cases.
