In recent years, researchers have conducted extensive studies on adjuvant therapy following surgical resection of liver cancer, exploring its potential benefits and seeking effective treatment strategies. Given the rarity and high aggressiveness of primary hepatic sarcomatoid carcinoma, there is a lack of reliable clinical evidence on whether postoperative adjuvant therapy can benefit patients, resulting in the absence of established standard guidelines. Therefore, we conducted a single-center retrospective study to assess the potential benefits of postoperative adjuvant therapy for patients of primary hepatic sarcomatoid carcinoma.
