Puncture injection of para-toluenesulfonamide combined with chemoembolization for advanced hepatocellular carcinoma

Figure 2 The following para-toluenesulfonamide injections resulted in a significantly improved clinical prognosis. A: Contrast computer tomography (CT) after the first 5 para-toluenesulfonamide (PTS) injections demonstrated a decreased nodule with partial retention of lipiodol. Remarkable necrosis and no blood supply were found in the rest part of the tumor; B: Two months after the last 3 PTS injections, contrast CT revealed homogeneous dense retention of lipiodol within the entire tumoral mass and no recurrent lesion was identified.
