Background: Perforated gastric cancer (PGC) is a rare condition of gastric cancer (GC). In this study, we sought to assess the outcome of PGC from the aspects of both acute care surgery and surgical oncology at a single institute, Chang Gung Memorial Hospital (CGMH).
Methods: From 1997 to 2013, 6864 patients were diagnosed with GC and 2738 were diagnosed with gastroduodenal perforation at CGMH. In total, 29 patients with PGC were identified. Immediate surgical and long-term oncologic outcomes were evaluated after an appropriate matching process was performed.
Results: The immediate surgical outcome of PGC, i.e., the hospital mortality rate within 30 d after surgery, did not significantly differ from that of non-cancer related gastroduodenal perforation. The long-term oncologic outcome, with matching by age, gender, year of surgery and AJCC 7th stage grouping, also did not significantly differ from that of GC without perforation.
Conclusions: Aggressive surgical treatment, including an initial emergency procedure for containing peritonitis and radical surgery for GC, may benefit PGC patients in terms of both the immediate and oncologic outcomes.
