Core Tip
Core tip: From 1997 to 2017, we collected seven cases of gallbladder sarcomatoid carcinoma at our institution. By reporting these cases, this paper will enrich the clinical information of this rare tumor. TNM stage seemed to be a highly important prognostic indicator. There was a significant difference in prognosis between patients with early-stage and advanced-stage disease. For the first time, we report a patient treated with postoperative adjuvant therapy who achieved a progression-free survival for up to 12 mo. This approach may provide a potential strategy for gallbladder sarcomatoid carcinoma, which is a kind of rare and aggressive tumor with no standard treatment to date.
