Multidisciplinary treatment of advanced or recurrent solid pseudopapillary neoplasm of the pancreas: three case...

Solid pseudopapillary neoplasm (SPN) is a rare pancreatic tumor that predominantly affects young females. Prognosis is excellent; however, 10-15% of patients show metastasis at the time of surgery or develop tumor recurrence after pancreatectomy.

We reviewed the clinical course of three patients with advanced or recurrent SPN and subsequently underwent multidisciplinary treatment at our institution between 2002 and 2019. The primary tumor was resected in all three patients, and metastases were also resected if indicated. Intensive combined therapy, including re-resection, chemotherapy, ablation, arterial chemoembolization, and radiation therapy, allowed all patients to survive for a long time. The literature review showed that resection seems to be more effective than other treatments for metastatic SPN.

Multidisciplinary treatment, including resection, may improve the prognosis of patients with SPN with recurrence or metastasis.
