Cross-sectional Follow-up on Digestive and Social Functions of SPN

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

An observational cross-sectional follow-up study on the quality of life (two aspects, digestive physiological and social psychological functions) of solid pseudopapillary neoplasm of the pancreas (SPN) patients recruited in PUMCH from 2001 to 2026. The quality of life is evaluated by a questionnaire made up of eight validated scales.

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.
