915 MHz microwave interstitial hyperthermia. Part I: Theoretical and experimental aspects with temperature control by multifrequency radiometry.

Microwave interstitial hyperthermia now plays an increasing part in the various hyperthermia techniques used in cancer treatment. This paper will present the design, construction and theoretical as well as experimental study of miniature coaxial antennas designed to heat tumours of various volumes and sizes. Monitoring temperature using multifrequency radiometry during hyperthermia stems naturally from the very design of these antennas. Experiments on phantoms, animals and patients in phase I clinical assessment have demonstrated that microwave interstitial hyperthermia can be achieved with temperature control and monitoring by microwave radiometry.

[Primary cancer of the vagina and indications for therapy: on the basis of 52 cases]. / Le cancer primitif du vagin et ses indications thérapeutiques. A propos de 52 observations.

The authors studied 52 cases of primary cancer of the vagina, 7 stage I, 23 stage II, 7 stage III, and 15 stage IV. For every one primary cancer of the vagina they found 58 cancers of the cervix, 6 cancers of the endometrium, 5 cancers of the ovary, and 4 cancers of the vulva. The extent of these cancers at the time of the first examination is explained by their clinical latency. Treatment was by radiotherapy (radium therapy and telecobaltotherapy) with or without surgery. At present the 5-year survival rate is 23.8 percent. The use of high-energy therapy should lead to a distinct improvement in the results.
