RESUMEN
PURPOSE: To assess the efficacy and the tolerance of a split course hypofractionated (SCH) radiotherapy (RT) protocol in head and neck cancer (HNC) for eldery and/or unfit patients (pts). PATIENTS AND METHODS: Pts with HNC treated by SCH-RT in two institutions were included retrospectively. The main SCH RT regimen was two courses of 30 grays (Gy)/10 fractions separated by 2-4 weeks, without any systemic therapy. RESULTS: Between February 2012 and January 2019, 75 consecutive patients were analyzed. The median age was 80 years (range: 45.7-98.2) and 53 (70.7%) were men. Sixty-one (81.3%) pts had stage III/IV disease and 54 (72%) had at least two comorbidities. All of them were treated with intensity-modulated radiotherapy. Median follow-up was 10.6 months (range: 3.1-58.3). Local control at 12 and 24 months was 72.8% IC95%[62-85.5] and 51.7% IC95%[38.1-70.1] respectively. Progression free survival (PFS) at 12 and 24 months were 47.7% IC95%[37.4-60.8] and 41% IC95%[15-36.4] respectively, with a median of 11.5 months IC95%[8.9-17]. OS at 12 and 24 months were 60.4% IC95%[50-73.1] and 41% IC95%[30.6-54.9] respectively, with a median of 19.3 months IC95%[11.9-25.8]. Acute and late grade 3 or higher toxicities occurred for 6 (8%) and 3 (4%) pts. CONCLUSION: The present SCH-RT regimen seems effective, well-tolerated and could represent an alternative to palliative strategies for pts deemed unfit for standard exclusive RT.

Thyroid cancer is an uncommon cancer. Molecular biology plays a vital role in its development. Chemotherapy showed unsatisfactory results in advanced stages where surgery and iodine therapy are not appropriate. These last ten years have been marked by a major advance in understanding the molecular features of this cancer and therapeutic correlations, moreover, clinical trials have focused on the treatment of this disease on metastatic stages and led to a significant therapeutic panel targeting angiogenesis, mutations frequently found in cervical cancer: RET, BRAF, RAS... these are the motesanib, axitinib, sunitinib, pazopanib, vandetanib, cabozotinib and sorafenib. The last three molecules have already the autorisation of FDA and EMA. In this review, we will put the item on oncogenetic characteristics of thyroid carcinoma as well as new targeted therapies in patients refractory to conventional treatment.
