GIANT-CELL TUMOR OF METACARPALS - REPORT OF 3 CASES

Giant cell tumour of the metacarpal bone is rare. We have encountered three cases during the last 30 years. Surgical treatment is difficult in such a critical site and is always associated with functional defor mities and poor cosmesis. We have successfully treated two males and o ne female with lesions of the Ist, 2nd and 4th metacarpal bones using a Theratron-60 telecobalt machine. The radiation dose delivered was 50 -55 Gy over 4.5-5 weeks. The three patients all tolerated radiotherapy treatment well, though moderate radiation dermatitis (Grade II-III) w as seen. The regression of tumour mass started after about 2 months of radiation therapy and complete regression occurred after several mont hs. The pain subsided immediately. Long follow up of 7-11 years reveal ed no signs of local recurrence, distant metastasis or radiation induc ed malignancy. The results of radiation therapy are excellent in terms of functional integrity and cosmesis.
