Introduction: Chordoma is a rare bone tumor, which develops mainly from the sacrum, the base of the skull, or the spine. Surgery + radiotherapy (if necessary) is the standard treatment. Data on chordoma are scarce in this region, and thus, here we summarized 9 patients with this tumor whom we treated in this institute. Material: Nine chordoma patients were summarized, who were treated in National Institute of Oncology in Rabat between 2013 and 2018. We retrieved data from medical charts and analyzed the clinical characteristics of this tumor. Results: The average age was 49 years (range: 29 - 72), with male: female of 3:6. The manifestation-diagnosis time was 4 months (range: 2 - 14). Regarding the tumor location, lumbosacral spine;5, the skull;4. Mass was evident in 6. Signs of locoregional compressions (paraparesis or tetraparesis) were observed in 3. As for treatment, a partial tumor excision was performed in 8, with 3 patients undergoing a wide excision. Radiotherapy was done;3 patients with a dose of 46 Gy, 3 patients with 66 Gy, 1 patient with 50 Gy, and 1 patient with a 16 Gy gamma radio-knife in a single session. 4 patients with a dose of 46 Gy, 2 patients with 60 Gy, and 1 patient with a 16 Gy gamma radio-knife in a single session. Of 9, 4 patients had good locoregional control whereas 5 patients had local recurrence. Conclusion: a. style="font-fa.ily:Verda.a.">Chordoma.is a.predomin

Introduction: To determine the proportion and the reasons which lead to palliative treatment in patients initially a candidate for concomitant chemoradiotherapy (CCRT). Methods: A retrospective study including patients followed for locally advanced lung cancer newly diagnosed from April 1, 2016, to 12/31/2017 in the radiotherapy department of the National Oncology Institute who received palliative treatment. Results: We collected 52 patients out of a total of 225 stage III patients (23%) followed by lung cancer candidates for CCRT who had undergone palliative treatment. The mean age in our series was 61.23 years [22 - 81] with 86% male. The majority of patients (71%) had Performance Status (PS) ≤ 2. Histological confirmation was obtained by pathological examination in all our patients. It was an adenocarcinoma (ADK) in 54% of cases;squamous cell carcinoma in 46% of cases. The reasons for palliative treatment were mainly due to dosimetric constraints: large tumor volume 22/52 (42%);the tumor location close to the bone marrow in 15 of 52 (29%) patients;and general Performance Status impairment (29%) in 15 of 52 patients. Palliative treatment consisted of palliative chemotherapy in 37 of 52 patients (71%), a. style="font-fa.ily:Verd
