Can we recommend surgical treatment to the octogenarian with periampullary cancer?: National database analysis in South Korea.

ABSTRACT

BACKGROUND: The incidence of periampullary cancer in the elderly is increasing. Safety and oncologic effectiveness of pancreaticoduodenectomy in elderly patients is still controversial. MATERIALS AND METHODS: From 2002 to 2016, patients with periampullary cancer were evaluated. Customised health information data provided by the National Health Insurance Corporation (NHIS-2018-1-157) were used for analysis. Chronological changes in the incidence of periampullary cancer and long-term survival outcomes were estimated according to patients' age. RESULT: A total of 148,080 patients were found to have periampullary cancer. Chronologically, the incidence of periampullary cancer increased, and the proportion of elderly patients with periampullary cancer prominently increased (about 2.1 times in patients in their 70s and about 4.7 times in those older than 80 years). The number of patients with pylorus-preserving pancreaticoduodenectomy in their 70s (about 5.6 times, p < 0.001) and over 80 years of age (about 8.9 times, p < 0.001) was much higher than the number of patients aged younger than 50 years (about 1.7 times) and in their 60s (about 2.5 times). Long-term survival was different as per diagnosis (p < 0.001). In addition, it was observed that age was a factor attenuating the survival of patients with resected periampullary cancers (p < 0.001). However, in case of patients older than 80 years, those who underwent surgical treatment showed a higher survival rate than those who did not undergo surgical treatment. CONCLUSION: We can recommend surgical treatment for elderly patients with resectable periampullary cancer. The survival data in this study can be useful references especially in making treatment plan for octogenarians diagnosed with periampullary cancer.
