Nonetheless, intra-thoracic lymph nodes are detected with greater clarity in the adult cats that have the larger lymph node width, specifically in the male cats whereas gonadal status, BW and BCS do not affect lymph node detection. In oncology, the correct determination of nodal metastatic disease is essential for patient management, as patient treatment and prognosis are closely linked to the stage of the disease.
