An Observational Cross-sectional Follow-up Study on Digestive Physiological and Social Philosophical Functions of Solid Pseudopapillary Neoplasm of the Pancreas (SPN)

Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare tumor with uncertain malignant potential. It is a rare entity of pancreatic tumor with low potential malignancy, constituting 1% to 3% of pancreatic tumors and 10%-15% of pancreatic cystic neoplasm. Although the reported cases of SPN have been increasing rapidly all over the world during the last two decades, its long-term follow-up studies in large cohorts remain missing.

From this, this observational cross-sectional follow-up study on the digestive physiological and social psychological functions of SPN patients aims to achieve a comprehensive understanding on how SPN and surgery affects the quality of life. Patients are recruited in PUMCH from 2001-2026 with a definite pathological diagnosis.

The quality of life after surgery is evaluated by a questionnaire made up of six validated scales (digestive physiological functions via: 8 symptoms scale of the EORTC core quality of life questionnaire (EORTC QLQ-C30); gastrointestinal symptom rating scale questionnaire (GSRS); social psychological functions via: sense of coherence-9 questionnaire (SOC-9); patient health questionnaire-9 questionnaire (PHQ-9), general anxiety disorder-7 questionnaire (GAD-7) ; post-traumatic embitterment disorder 21 questionnaire (PTED-21); work ability index questionnaire (WAI); body image scale questionnaire (BIS)). To our knowledge, this is the largest SPN cohort worldwide and the first study to concentrate on the quality of life of SPN after operations.
