Tumeur à cellules géantes de la main: Résultats du traitement : 5 cas au recul moyen de 7,8 ans

Abstract

Purpose of the study Giant-cell bone tumors are benign but have great potential for recurrence. Frequently observed in epiphyseal areas of tubular bones, these tumors are rarely found in hand localizations. We examined the characteristic features of giant-cell tumors of the hand and analyzed the pertinence of surgical treatment. We noted complications, consequences of recurrence and later operations on the same tumor site in five cases. Case reports Five patients treated between 1973 and 2000 for giant-cell tumors involving the hand bones were reviewed retrospectively. Mean age was 41.6 years and mean follow-up was 7.8 years. The surgical procedure was curettage for two, curettage with bone graft for two and amputation for one. The Enneking score was noted. Results Pain was the main symptom, with local swelling in several cases. At 7.8 years follow-up recurrence was noted for four of the five tumors. Two patients were treated for a second recurrence. Amputation of the forearm was required for one recurrence affecting soft tissue. Mean time between two consecutive recurrences was three months. In all six episodes of recurrent tumor were treated. These five patients had a total of ten operations. There were no cases of metastasis nor multicentric foci. Discussion Treatment of giant-cell tumors involving the hand bones is designed to eradicate the tumor and also protect hand function while keeping in mind the aggressive nature of these benign tumors. Surgical alternatives for radical treatment can include wide resection, resection of the ray and amputation.
