Doctors at Narayana Super-speciality Hospital (NSH), Howrah performed the first Extracorporeal Radiotherapy (ECRT) case in Eastern India on July 19, 2018. The cancer affected bone was taken out of the body for high intensity radiotherapy and then re-implanted post treatment. In ECRT radiation is given at 50 Gy for about 20-25 minutes, while normal radiation given to any cancer patient is 30 Gy over 4-6 weeks. In a case, Iman Hossain, a 13 years old patient from Agartala was brought to NSH with severe pain and swelling in the right hand in August, 2017. Clinical examinations including Biopsy, PET Scan, X-Ray and MRI revealed that he was suffering from Ewing Sarcoma (Bone Cancer) in the right forearm. A multi-disciplinary tumour board was formed to offer a curative treatment instead of other treatment options like amputation or external beam radiation. The treatment included pre-surgery chemotherapy (Neo Adjuvant) and post-surgery chemotherapy (Adjuvant) as well.The unique point is that the cancer had spread in the entire ulna-bone (forearm). The 8 hours long surgery included taking out the bone, giving radiation and re-implantation of the tumour free irradiated bone. The ligaments at the wrist, elbow joints and the forearm skin were also reconstructed by the Musculoskeletal Oncology team and overlying skin defect was covered by Plastic Surgery Team. The patient was discharged seven days after this successful surgery.
