Se (9). In sufferers with renal cell carcinoma (RCC) treated with sorafenib, Johannsen et al (14) observed that recurrent or new metastatic lesions created following discontinuation in the drug in five out of 12 sufferers who accomplished a CR. A additional accumulation of circumstances is required to understand theappropriate timing of your discontinuation of sorafenib soon after a CR is accomplished. In conclusion, the present study described a case of sophisticated HCC with PVTT that showed a CR following therapy with low-dose sorafenib (400 mg when every day) and in which this CR was maintained for roughly a single year just after therapy was discontinued. Tumors could recur resulting from the discontinuation of therapy, as well as the suitable timing of sorafenib discontinuation calls for further investigation.
