Kokeellinen: Partial TACE Enhancing Anti-tumor Response with Lenvatinib in unresectable HCC
Lenvatinib: Oral administration at 12 mg once daily (body weight ≥ 60 kg) or 8 mg once daily (body weight < 60 kg). Treatment continues until disease progression, unacceptable toxicity, or patient withdrawal. Partial TACE: Performed within 4 weeks after starting lenvatinib. |
Oral lenvatinib 12 mg once daily for body weight 60 kg or greater, or 8 mg once daily for body weight less than 60 kg.
Treatment continues until disease progression, unacceptable toxicity, or patient withdrawal.
Transarterial chemoembolization targeting up to two liver segments containing the largest tumor volume or lesions at risk of rupture, performed within 4 weeks after starting lenvatinib.
This liver-function-sparing approach limits the ischemic territory in order to preserve hepatic reserve.
