Eficacia en el diagnóstico histopatológico de tumores músculo esqueléticos con biopsia percutánea

Abstract

Musculoskeletal tumors have a low worldwide frequency; therefore, an appropriate sampling method is essential for an adequate diagnosis. Although, an open biopsy type is the gold standard, new studies demonstrate that percutaneous sampling with a thick needle has presented advantages such as cost reduction, low hospital stay, few adverse effects, and equal effectiveness compared to the gold standard procedure.

Aim: To demonstrate the effectiveness of percutaneous thick-needle biopsies for an adequate diagnosis of musculoskeletal tumors in patients who attended the orthopedic oncology service at SOLCA Hospital in Quito - Ecuador, between January 2013 and December 2015.

Materials and methods: 143 patients were studied through an observational, descriptive and prevalence study. The study considered all patients treated in the orthopedic oncology service that fulfilled all inclusion criteria and required a percutaneous biopsy sample collection with a thick needle for the diagnosis of musculoskeletal tumors.

Results: The majority of patients were adult females. An open biopsy was not necessary in 90% of patients for a conclusive histopathological diagnosis. Nonetheless, 21% of cases required a new biopsy. Benign tumors were predominantly observed in most cases 58% and a 6.3% did not have a diagnosis.

Conclusion: Percutaneous thick needle biopsies are an effective method for an adequate diagnosis of histopathological musculoskeletal tumors.
