The Paris System is a previsional dosimetric system which facilitates the work of curietherapists working with iridium 192 wires. Introduced about twelve years ago for radio-active implantations in one linear plane, this system has now become more generalized for implantations in two or more linear planes. After a brief review of the principles on which the Paris System is based, and introducing the new definitions arising from its development, the authors present the results of a systematic computerized study. The results obtained were used to establish, among others, the simple relationships between the geometric implantation data (disposition, length, number, separation... of the radioactive lines) and the dimensions of the volume treated, for the coplanar patterns and those called "in squares",

Between 1966 and 1977, 142 breast cancers have been discovered in 85 250 women among 120,000 routine clinical examinations. Comparison between the information given by mammography alone compared with the panel of specialized techniques (cytology, thermography, mammography, echography) shows superiority for the latter. Complete breast check-ups have doubled the percentage of cancers discovered in the women that were examined (from 0,8% to 1,8%). A family history of breast cancer does not help in the discovery of cancer, except in cases of mammary changes noticed by the patient herself. However, these women have to be checked regularly, because the number of cancers diagnosed does not decrease at subsequent visits. The generalized practice of self-examination and of less mutilating treatment should encourage patients to consult earlier, as they have less fear that mutilating surgery will be performed.

A new method of irradiation known as hyperfractionated radiotherapy was studied in 56 patients with cancers in the region of the ear, nose, and throat. The dose was 72 grays given during 80 sessions over a period of 28 days, with a rest period of two weeks at the half-way point. Each session lasted 2 hours. The results (complications and survival rate) were compared with those obtained in a control group treated with 70 grays in 35 sessions over a period of 7 weeks. The complication rate was 21% in the series treated with hyperfractionated radiotherapy, against 19% in those given classical treatment (results not significant). The survival rate was better, however, (63% against 33% after 18 months), for the patients treated with this new method of irradiation.
