ABSTRACT
Abstract Objective Extended curettage with adjuvants of giant cell tumors of bone is associated with a lower rate of recurrence of the tumor while preserving the adjacent joint. The present study was conducted to estimate the recurrence rate and functional outcome after using argon beam as an adjuvant for extended curettage. Methods We selected 50 patients with giant cell tumors, meeting all the inclusion criteria, who underwent extended curettage using high speed burr and argon beam photocoagulation between July 2016 to January 2019. On their follow-up visit, they were assessed for any complaints of pain and signs like tenderness, locally raised temperature, and decreased range of motion of the adjacent joint. Radiologically, the patients were assessed for any increased lucency around the cement mantle and uptake of the subarticular graft. Musculoskeletal Tumor Society Score (MSTS) was administered to the patients, and range of motion of the adjacent joint was compared with the contralateral joint. Results Recurrence was found in 4 patients, that is, an 8% recurrence rate. Twenty-six out of 28 patients with a tumor in the lower limb had a grade-5 weight bearing status 6 months from the surgery, and their range of motion was comparable to contralateral healthy joint with an average MSTS score of 27 (18-30). Conclusion Extended curettage of giant cell tumors using argon beam coagulation is associated with low recurrence rates of the tumor and is an effective modality in the treatment of these tumors besides having a functional outcome comparable to the healthy limb.
RESUMO
Resumo Objetivo A curetagem estendida com adjuvantes de tumores de células gigantes do osso está associada a uma menor taxa de recidiva da neoplasia e à preservação da articulação adjacente. Este estudo foi feito para estimar a taxa de recidiva e o resultado funcional após o uso de plasma de argônio como adjuvante à curetagem estendida. Métodos Cinquenta pacientes com tumores de células gigantes que atendiam a todos os critérios de inclusão foram selecionados para o estudo e submetidos à curetagem estendida com broca de alta velocidade e fotocoagulação com plasma de argônio entre julho de 2016 e janeiro de 2019. À consulta de acompanhamento, os pacientes foram avaliados quanto a quaisquer queixas de dor e sinais como sensibilidade, aumento local da temperatura e diminuição da amplitude de movimento da articulação adjacente. Radiologicamente, os pacientes foram avaliados quanto à presença de qualquer aumento de radiotransparência ao redor do manto de cimento e incorporação do enxerto subarticular. O questionário Musculoskeletal Tumor Society Score (MSTS) foi administrado aos pacientes e a amplitude de movimentação da articulação adjacente foi comparada à articulação contralateral. Resultados Quatro pacientes apresentaram recidiva, o que corresponde a uma taxa de 8%. Seis meses após a cirurgia, 26 de 28 pacientes com tumor no membro inferior tinham capacidade de sustentação de peso de grau 5 e amplitude de movimento comparável à articulação saudável contralateral, com pontuação MSTS média de 27 (intervalo de 18 a 30). Conclusão A curetagem estendida de tumores de células gigantes com coagulação por plasma de argônio está associada a baixas taxas de recidiva da neoplasia; é uma modalidade eficaz no tratamento desses tumores e o resultado funcional é comparável ao do membro saudável.
