RESUMEN
PURPOSE: The main objective of this study was to evaluate the 5-year efficacy of exclusive laryngeal radiotherapy without node prophylactic irradiation for localized cancers of the vocal cords. PATIENTS AND METHODS: We retrospectively reviewed charts from 258 patients with T1-T2N0 glottic carcinoma irradiated from April 1987 to March 2015 in four France western centers, including pretreated patients. Toxicity was analyzed according to CTCAE v4.0 classification. RESULTS: The median follow-up was 50 months. The median age was 67 years with 87% men and 85.5% had T1 tumor. Five years overall survival was 77.5% (95% confidence interval [95% CI]: 71.4-83.5), 5 years local control was 86.8% (95% CI: 82.3-91.3), specific survival rate was 95% (95% CI: 92.2-97.9) and final laryngectomy-free survival was 87.5% (95% CI: 82.2-92.9). Most toxicities were grade 1 and 2. Grade 3 acute toxicity was 15.5% for the radiation laryngitis, 3.5% for radiodermatitis and 7.7% for dysphonia. Grade 3 chronic toxicity was 3.5% for dysphonia and there were two cases of tracheal stenosis treated by tracheotomy. CONCLUSION: Radiotherapy provides good results in local control of stage I and II vocal cords cancers as well as the toxicity level.

Epithelioid hemangioendothelioma is a rare vascular tumour, with features between hemangiomas and angiosarcomas. Evolution remains mainly local but may also metastasize. Here, we report a case of a patient with a spinal epithelioid hemangioendothelioma. After a first resection, local recurrence required a new excision and external radiotherapy. It was achieved by helical TomoTherapy® with intensity modulation. During the follow-up, a second inoperable spinal location necessitated a new sequence of radiotherapy in modulation of intensity with integrated boost. The patient was alive at 24 months of follow-up without evidence of local relapse or distance. This observation is followed by a discussion with review of the literature on other epithelioid hemangioendothelioma cases treated with radiation.

Anal canal epidermoid carcinomas represent 1.2% of digestive cancers and 6% of ano-rectal cancers. For localized diseases, the treatment is based on radiotherapy with or without chemotherapy (5-FU and cisplatin or mitomycin), according to tumour and nodal extension. The recommended treatment dose is 45 Gy in the anal canal, the mesorectum, pararectal lymph nodes, and inguinal lymph nodes. An additional dose of 15 to 20 Gy is delivered in the initial tumour for good responders. Salvage surgery is necessary in case of poor response. The organs at risk to be considered are bladder, femur heads, small intestine and vulva. The objective of this work is to summarize the epidemiological and radio-anatomic and prognostic characteristics of this tumour. The conformal radiotherapy technique is illustrated by a case report.

In view of preparing a controlled trial to assess the efficacy of screening for colorectal cancer by fecal occult blood testing in reducing cancer mortality, a pilot study was performed to evaluate the acceptability rate of the Hemoccult test in non selected subjects consulting in a general practice. 566 subjects aged 45 to 74 years from two small towns, Neuville-aux-Bois (Loiret) and Vicherey (Vosges) were included in the study. The screening test was proposed by GPs to 89.2% of their patients; of these, 5.6% refused the test and 9.4% did not return it. Of the tests carried out, 80.8% were performed spontaneously, and 19.2% after a recall letter. Acceptability depended neither on age or on sex. The patients' confidence in his GP was the most important acceptability factor (60%), followed by explanations the GP had provided, and ease of application. The results suggest that after receiving the correct information, a GP will succeed in prescribing the Hemoccult test to most high-risk subjects and that acceptability then proves excellent. Experience drawn from the pilot study has been very useful in conceiving the on-going controlled trial in Burgundy.
