De behandeling van een omvangrijke ribtumor bij een hond

摘要

A 12-year-old English Cocker spaniel was referred because of front leg lameness due to a mass on the right cranioventral thoracic wall. Radiographic examination showed that the limited external mass had a large intrathoracic component. The patient was staged, and based on the results of computed tomography, surgery was planned and the tumor was removed en bloc. An osteosarcoma with metastasis in the regional lymph nodes was diagnosed on histopathology. Consequently, chemotherapy was instituted. The disease-free period lasted four months, after which respiratory discomfort developed due to pulmonary metastases. The dog was euthanized five months after surgery.This case illustrates that a sufficiently aggressive, multimodal treatment may prolong life expectancy in case of an advanced, malignant tumor.
