PURPOSE Olfactory neuroblastoma or esthesioneuroblastoma is a rare entity among head and neck neoplasms. In this paper, we report the experience of our institution and compare it with a comprehensive review of the literature. PATIENTS AND METHODS We retrospectively analysed clinical and treatment data of patients referred to the Lyon Sud University(More)
PURPOSE To analyse the dosimetric differences between the conventional conformal radiation therapy (CR) and the volumetric modulated arc therapy (VMAT) for non-small-cell locally advanced lung cancer (NSCLC). PATIENTS AND METHODS Two plans (CR and VMAT) were calculated for ten NSCLC patients. Dose to PTV, organs at risk and external contours (body),(More)
Granulocytic sarcoma, or chloroma, is a rare clinical entity, usually associated with a blood disease, including acute myeloid leukemia. Management strategies are based on the combination of systemic therapy and local therapy (surgery or radiation). Data for radiotherapy dose are derived from retrospective studies and case reports. We conducted a literature(More)
PURPOSE The implementation of intensity-modulated radiotherapy (IMRT) in a centre requires regular critical review of medical practices and feedback to optimize the subsequent management of patients. PATIENTS AND METHODS We reviewed and determined through a retrospective single-centre study recurrence sites of 167 consecutive patients treated for head and(More)
Neuroendocrine prostate carcinoma is a rare entity causing both diagnostic and therapeutic issues. There are basically four histological forms (adenocarcinoma with neuroendocrine differentiation, carcinoid tumors, small cell neuroendocrine carcinomas, large cell neuroendocrine carcinomas), which can be pure or mixed associated with prostatic carcinoma.(More)
Primitive lymphomas of the bone are exceptional tumors, representing 4% of all non-Hodgkin lymphomas. The location at the skull remains the rarest. We report the case of a 56 year old patient with lytic lesions in the skull of a small cell lymphoma B, treated with primary chemotherapy and intensity-modulated radiotherapy in arctherapy with a dose of 30Gy in(More)
OBJECTIVES We retrospectively compared survivals in patients with a lung cancer history and followed by the so-called sentinel Web-application that allows early detection of relapse and early palliative care initiation versus a conventional follow-up in our center. METHODS The survival in 98 consecutive patients with lung cancer was assessed. The first(More)
Urothelial carcinomas of the upper urinary tract are rare entities. Surgery remains the mainstay of the management. The use of others therapeutic modalities is not clearly defined yet. However, the frequency of local recurrence and locoregional encourage us to evaluate the indication of adjuvant therapies. We conducted a synthesis of key data in the(More)
PURPOSE Evaluation of perioperative treatment of keloid scars with electron beam therapy or iridium 192 low dose rate brachytherapy. PATIENTS AND METHODS From 1994 to 2010, 95 patients with 142 keloid scars have been treated by immediate perioperative irradiation and retrospectively reviewed in our institute: 116 scars were treated by electrontherapy and(More)
