Background/Aims: There have been little research on the cancer risks of patients with Peutz-Jeghers syndrome (PJS) in Korea.
We aimed to investigate the clinical features of PJS patients and their cancer incidence rate.
Methods: Patients with PJS from nine medical centers were enrolled. In those patients diagnosed with cancer, data obtained included the date of cancer diagnosis, the tumor location, and the cancer stage. The cumulative risks of gastrointestinal cancers and extra-gastrointestinal cancers were calculated using the Kaplan-Meier method.
Results: A total of 96 PJS patients were included. The median age at diagnosis of PJS was 23.4 years. Cancer developed in 21 of the 96 patients (21.9%). The age of PJS diagnosis was widely distributed (0.9 to 72.4 years). The most common cancers were gastrointestinal cancer (n = 12) followed by breast cancer (n = 6). The cumulative lifetime cancer risk was calculated to be 62.1% at age 60. The cumulative lifetime gastrointestinal cancer risk was 47.1% at age 70. The cumulative lifetime extra- gastrointestinal cancer risk was 40.3% at age 60.
Conclusions: PJS onset may occur at any age and the risks of gastrointestinal and extra-gastrointestinal cancer are high.
Thorough surveillance of PJS patients for malignancies is vital.
