Abstract:
To explore the clinical features, pathological features, gene test results, diagnosis, treatment and prognosis of Peutz-Jeghers syndrome(PJS).
Methods: We retrospectively analyzed clinical data of 46 hospitalized cases of PJS during 2007 and 2017.
Results: All 46 patients had mucocutaneous melanin pigmentation and multiple gastrointestinal polyposis. The pigmentation was first noticed often within 5 years old, and 14 cases had family history. The clinical manifestations mainly included black spots, abdominal pain, hematochezia, and anemia. Histological examinations showed that 20 patients were classified as hamartomatous polyps,18 as adenomatous polyps, 14 as inflammatory polyps, and 10 as zigzag polyps. Eleven patients sequenced a panel of 20 genes previously associated with colorectal cancer (CRC) by next-generation sequencing, and the results showed 5 patients with gene mutations, and 3 of them with intussusception and surgical histories were found to have pathogenic germline mutations in the STK11 gene. Endoscopic treatment was the main therapy, but endoscopy combined with laparoscopy or surgical treatment was performed when complications occurred or the polyp was too large. Malignant tumors were found in 3 patients during follow-up.
Conclusion: PJS is a hereditary disease which is characterized by spots of the skin or mucosa and gastrointestinal multiple polyps. The main pathological features are hamartoma and adenoma. The risks for intussusception and surgical operation are found to be high in the patients with pathogenic germline mutations in the STK11 gene. Endoscopic treatment is the main therapy. PJS patients should be followed up regularly due to the increasing risk for cancer and being easily to relapse.
