Abstract:
Ewing sarcoma is a highly malignant neoplasm of bone or soft tissues that is predominantly seen in adolescents and young adults. Patients with recurrent and metastasis have poor survival despite aggressive treatment. In Ewing sarcoma, EWS-FLI-1 translocation has been identified as a biomarker for Poly-ADP ribose Polymerase inhibitor (PARPi) sensitivity and olaparib has been shown to enhance the antitumor activity of chemotherapy agents like temozolomide, irinotecan, and trabectedin. We tried the combination of olaparib and temozolomide in an adult patient of Ewing sarcoma who had metastatic disease, and after 4 months of treatment, he showed excellent response to treatment.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
