Peutz-Jeghers syndrome and duodeno-jejunal adenocarcinoma--therapeutic implications

The Peutz-Jeghers syndrome (PJS) is an autosomal dominant hamartomatous poliposis describred in 1921. Hemminki in 1997 described the presence of LKB-1 mutation tumor-suppressor gen. The patients with PJS develop a higher cumulative incidence of gastrointestinal, pancreas and extraintestinal tumors, being oc casion of a renew interest on hamartomatous polyposis syndro mes regarding the clinical care, cancer surveillance treatment and long term follow-up. We report the case of a 38 years old male, diagnosed of PJS who developed a multiple adenocarcinoma in duodenum and ye yunum. Surgically treated and with a long-term free disease survival of 11 years represents the sixth case reported in the spanish literature of PJS associated with a gastrointestinal tumor. A critical review, molecular alterations and the established criteria of tumor screening and surveillance are reviewed.
