Abstract:
The patient was a 75-year-old woman who had undergone an operation for T4, N0: stage IV a gall bladder cancer in May of 2003. UFT was given as adjuvant chemotherapy. Then S-1 and gemcitabine (GEM) were given because of the recurrence of peritoneal dissemination in June 2006. Though a partial response was maintained, it was judged as progressive disease in July 2007. The peritoneal tumor was solitary, and an operation was performed. S-1 and GEM were given again in January 2008 because of multiple lung metastases. Long-term survival was confirmed until she died of peritonitis carcinomatosa in August 2009. To our knowledge, no case of a long survivor with S-1 and GEM for recurrence after a gall bladder cancer operation has been reported in the literature. Thus, future clinical trials and the accumulation of further cases are warranted.
