Clinical analysis on gastrointestinal stromal tumor patients with hepatic metastases: 24 cases report / 肿瘤研究与临床

ABSTRACT

Objective To analyze the clinical characters,treatment effects and influential factors of gastrointestinal stromal tumor patients with hepatic metastases,and to explore the reasonable clinical treatment protocols.Methods The clinical data of 24 gastrointestinal stromal tumor patients with hepatic metastases who were admitted to Peoples Liberation Army Hospital from April 2007 to April 2010 were retrospectively analyzed.Results The 1-,2-,3-and 4-year cumulative survival rates of hepatic metastases patients with gastrointestinal stromal tumors were 91％,72 ％,22 ％ and 6 ％,respectively.The 1-,2-and 3-year survival rates of the patients treated with imatinib after operation were 91％,70 ％,28 ％,respectively,the median survival time was 26 months,the mortality rate was 27.3 ％ (3/11),and 9 cases got the tumor complete elimination.The 1-,2-and 3-year survival rates of the patients treated without imatinib after operation were 90 ％,68 ％,18 ％,respectively,the median survival time was 24 months,the mortality rate was 14.3 ％ (2/13),and 12 cases got the tumor complete elimination.The recurrence rate after complete resection was 28.6 ％(4/14),and the mortality rate was 7.1％ (1/14).The mortality rate after incomplete resection was 40 ％ (4/10).Conclusion Surgical treatment of eliminating the primary and metastatic lesion,and adjuvant therapy of imtinib could prolong the survival time,reduce postoperative recurrence rate and improve the quality of life,which are the effective methods for the treatment of the gastrointestinal stromal tumor patients with hepatic metastases.
