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%), among whom 19 (51%) were stable after 2 months of chemotherapy, in palliative dose chest radiotherapy on the pulmonary parenchyma and/or mediastinum in 10 of 52 (19%) patients, and supportive care in 5 (10 %) patients. We observed 40/52 (77%) cases of stationary course, 04/52 (8%) cases of progress to metastases, and 08/52 (15%) deaths before radiotherapy. Conclusion: A large proportion of patients followed for locally advanced non-metastatic lung cancer are not eligible for curative treatment. The reasons for the palliative treatment of patients followed for lung cancer candidates for CCRT are variable but for a large proportion of patients due to the deterioration of their state of health during their diagnostic journey. Hence, there is the need to improve the early diagnosis and early management of patients with lung cancer to avoid delayed care.

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: Chordoma is a predominantly local aggressive tumor with low metastatic potential. The surgical excision remains the main prognostic factor. Advances in radiotherapy may improve local control. These data are of use in management of this tumor in Rabat (Morocco).

Introduction: Rhabdomyosarcoma (RMS) is the most common soft tissue tumor in children, with the head and neck location accounting for up to 40% of cases. The embryonal and alveolar histologic variants are more commonly seen in pediatric patients. The treatment is multimodal and the prognosis of this clinical entity is always gloomy. We report the case of nasopharyngeal rhabdomyosarcoma in a 7-year-old boy child with a good response to early post-therapy. Case Presentation: The patient was diagnosed with nasopharyngeal RMS revealed by a congested nose, ptosis and bilateral blindness, and who received induction chemotherapy followed by concurrent radiotherapy followed by adjuvant chemotherapy. The evolution is marked by a good clinical course but persistence of bilateral blindness. Conclusion: The RMS nasopharyngeal often presents with nonspecific symptoms. Multimodal therapy should be performed including surgery, chemotherapy and radiotherapy.
