Question:

Therapy for Askin tumor includes:
1. Surgery
2. Chemotherapy
3. Radiation therapy
4. Medical management
5. All of the above





Answer:

The correct answer for the question "Therapy for Askin tumor includes:" is:

5. All of the above



Explanation
Askin tumor is treated by multidisciplinary approach and not with any single unilateral approach. [Treatment for Askin tumor is generally a multidisciplinary endeavor with use of chemotherapy, surgery and external beam radiation therapy.]

Abstract
Askin tumor is a rare disease which had previously been reported as being thallium-201 and gallium-67 avid. Varying data regarding 18F-fluorodeoxyglucose metabolism has been described with Ewing family of soft tissue tumors. In this case, we present a patient found to have an Askin tumor of the left chest wall which demonstrated indium-111 pentetreotide and technetium-99m MIBI avidity. The lesion did not show 18F-fluorodeoxyglucose hypermetabolism in this case despite the aggressiveness of the tumor. The patient was treated with surgical excision of the tumor and chemotherapy. Subsequently, contrast enhanced CT, indium-111 pentetreotide and technetium 99m-MIBI showed that the lesion had regressed. These findings suggest that Askin tumor can demonstrate Indium-111 pentetreotide and technetium 99m-MIBI uptake and need not be hypermetabolic on 18F-fluorodeoxyglucose exam.
