Long-term survival of Askin tumor for 10 years with 2 relapses

An abnormal shadow was noted on a chest X-ray of a 32-year-old female in a medical check-up in March 1995, 3 months after she had given birth. Thoracic CT detected a tumor in contact with the left thoracic wall, and tumorectomy was performed in May 1995. The tumor was diagnosed as a primitive neuroectodermal tumor (PNET). After surgery, the thoracic wall to which the tumor adhered was treated with irradiation at 50 Gy. Chemotherapy was considered, but the patient did not wish to undergo this treatment. Lung metastasis occurred 5 years after the first surgery, and the left lower lobe of the lung was partially resected. Four years later, lobectomy of the left lower lobe of the lung was performed, due to further lung metastasis. The patient remains healthy as of April 2005.
