Adjuvant therapy in invasive intraductal papillary mucinous neoplasm (IPMN) of the pancreas: a systematic review

Forskningsoutput: TidskriftsbidragÖversiktsartikelPeer review

Sammanfattning

Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a cystic tumor with a disease spectrum ranging from low-grade dysplasia to invasive carcinoma. The evidence for adjuvant treatment in invasive IPMN is limited and mostly derived from studies in conventional pancreatic ductal adenocarcinoma (PDAC). We performed a systematic review focusing on all clinical studies concerning the efficacy of adjuvant therapy in patients with invasive IPMN. We identified 8 retrospective cohort studies, using either adjuvant chemotherapy alone (n=1), adjuvant radiotherapy alone (n=1) or adjuvant chemotherapy in combination with radiation (n=6). Adjuvant therapy was associated with a survival benefit in 7 out of the 8 studies. Specific survival benefit was noted for patients with node-positive disease, higher TNM stage, positive resection margins, poor differentiation and tubular subtype. We conclude that adjuvant therapy may be beneficial in invasive IPMN, but current data suggest that it should be given selectively based on individual tumor characteristics. Further prospective, randomized studies are warranted.
