FDG-PET imaging showed some correlation with pathologic response after ICT and CRT in patients with advanced SCCHN. The use of FDG-PET warrants further investigation in this setting.

Cutaneous malignant melanoma (CM) is the leading cause of skin cancer-related mortality and accounts for approximately 1,250 deaths in Canada each year. It is also one of few cancers continuing to display rates of increasing incidence throughout the world. The past decade has brought significant growth in our understanding of the pathogenesis and clinical management of CM. This evidencebased review synthesizes that knowledge, beginning with a review of the epidemiology and etiology of the disease followed by a broad review of the roles of diagnostic imaging in its management. Special attention is given to the role of 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography-computed tomography (PET/CT) in supporting assessment at primary presentation of disease, follow-up to surgical and nonsurgical treatment, and for the surveillance of high-risk asymptomatic patients. After a brief review of current treatment options, this article concludes with a demonstration of how and when uncertainty exists at the point of care systematic review processes may be used to resolve clinical questions. Learning Objectives:By the end of this Continuing Medical Education article, participants will be able to 1. Describe the epidemiology and etiology of cutaneous melanoma, 2. Describe broadly the role of diagnostic imaging in the clinical management of cutaneous melanoma, 3. Describe the specific roles and limitations of 18 F-FDG PET/CT in the clinical management of cutaneous melanoma, 4. Describe broadly the best practice in the treatment of cutaneous melanoma, 5. Define the value of systematic review for synthesizing knowledge pertaining to a specific clinical question, and 6. Discuss the utility of 18 F FDG PET/CT in the management of early-stage (AJCC 0-IIc) cutaneous melanoma.This is a CME article and provides the equivalent of 2 hours of continuing education that may be applied to your professional development credit system. A 12-question multiple choice quiz follows this reading. Please note that no formalized credit (Category A) is available from CAMRT.

Intracranial involvement by Hodgkin's disease is rare. We report a patient with Hodgkin's disease who had intracranial disease at presentation. We also review the literature pertaining to intracranial Hodgkin's disease. Using the key words "Hodgkin's disease" and "central nervous system (CNS) disease", we searched the Pubmed and Cancerlit databases. References were systematically reviewed and data regarding the following variables was extracted: age, gender, signs and symptoms at presentation, histology of Hodgkin's disease, cerebrospinal fluid analysis, stage and treatment. Only 36 cases of intracranial Hodgkin's disease were identified in the literature. Intracranial Hodgkin's disease at presentation is even more uncommon with only 8 reported cases. Most cases of intracranial involvement by Hodgkin's disease occur at the time of relapse. The most common presenting feature of intracranial Hodgkin's disease is a cranial nerve palsy with brain parenchyma being the most common intracranial site of involvement. Mixed cellularity histology is the most frequent subtype of Hodgkin's disease among these patients and the median survival following intracranial presentation is 46 months. Treatment has varied extensively but includes whole brain radiation with or without combination chemotherapy. Our literature review suggests that the prognosis is not dismal with appropriate treatment.
