The authors report a case of Dropped Head Syndrome with an unusually rapid onset after an accident in a patient with a history of Hodgkin's lymphoma cured by chemotherapy and mantle field radiotherapy and compare this case to the rare published cases of chronic Dropped Head Syndrome occurring after this type of treatment. A 56-year-old man was treated at the age 36 years for supra-diaphragmatic Hodgkin's lymphoma by chemotherapy and mantle field radiotherapy according to a standard technique and standard doses (40Gy, 20 fractions, 27 days). Seventeen years after the end of treatment, he experienced a violent whiplash injury, rapidly followed by a Dropped Head Syndrome, similar to the cases of chronic Dropped Head Syndrome already described in the context of Hodgkin's lymphoma (permanent flexion of the head, only reduced in the supine position). Physical and neurophysiological examination, electromyogram, and magnetic resonance imaging confirmed the diagnosis of Dropped Head Syndrome. Very few treatment options are available for the major disability related to Dropped Head Syndrome. This type of subacute onset of Dropped Head Syndrome has not been previously described. The good results of radiation therapy after chemotherapy allow a dose reduction to 30Gy in the involved regions. This, together with recent progress in treatment planning, should allow eradication of these complications., (Copyright © 2012. Published by Elsevier SAS.)

About 7200 new cases of pancreatic adenocarcinomas are diagnosed each year in France. At the time of diagnosis, an efficient carcinologic surgery will not be possible for nearly 80% of patients, in relation to loco-regional extension or metastatic dissemination. After surgical resection, the median survival of resected patients ranges from 12 to 20 months, with a high rate of relapses. Currently, the use of radiotherapy for patients with pancreatic cancer is controversial. In adjuvant setting, the standard treatment is six months of chemotherapy with FUFOL or gemcitabine. Chemoradiation (CRT) may improve the survival of patients with incompletely resected tumors (R1). This must be validated in a prospective trial. Neoadjuvant CRT is a promising treatment but always under evaluation. For the treatment of patients with locally advanced tumors, there is not a standart treatment. A strategy of initial chemotherapy followed by CRT for non progressive patients is under evaluation. Whereas in the first trials of CRT large fields were used, the current trend is to reduce the treated volumes to improve tolerance. The delineation of target volumes has been improved by the use of simulation CT. The aims of this work are to precise the radio-anatomical particularities, the pattern of spread of pancreatic cancer and the principles of 3D conformal radiotherapy illustrated with a clinical case., (Copyright © 2010 Elsevier Masson SAS.
