Article information
Los autores presentan cinco casos de timomas invasivos, haciendo énfasis en la importancia de un diagnóstico lo más precoz posible, basado en toda la batería habitual de exploraciones incluido la TAC. El carácter de malignidad de los timomas viene conferida por la invasión macroscópica de órganos de vecindad y/o presencia de metástasis intratorácicas. La estemotomía media representa la vía de abordaje de elección, planteándose las indicaciones de la telecobaltoterapia y de la quimioterapia complementarias, con las cuales dos de nuestros casos han alcanzado ya respectivamente los seis y los siete años de supervivencia.
We present five cases of invasivo thymomas. The need for an early diagnosis based on the available laboratory examinations including CT sean is emphasized. The malignant behaviour of thymomas related to the macroscopic invasion of surrounding organic stmctures and/or to the presence of intrathoracic metastasis. Middle sternotomy is the surgical approach of choice, with supplementary, telecobaltotherapy and chemotherapy according to their indications. By using this approach two of our cases have already survived for six and seven years, respectively.
