Solid pseudopapillary neoplasm — an uncommon tumour, usually curable with surgery

Solid pseudopapillary neoplasm, often abbreviated SPN and sometimes called by its older name, a Frantz tumour, is an uncommon type of pancreatic growth with a distinctive profile. It occurs predominantly in younger women, often in their teens, twenties or thirties — a demographic that sets it apart from most other pancreatic growths, which typically occur later in life. Unlike the fluid-filled cysts covered elsewhere in this cluster, an SPN has both solid and cystic components, which is reflected directly in its name.

The genuinely reassuring part of this diagnosis is that SPN is considered to have low malignant potential, and the great majority are cured with surgical removal alone. It can occasionally behave more aggressively or, uncommonly, spread beyond the pancreas, but this is the exception rather than the expectation, and even then outcomes after appropriate treatment are generally favourable compared with most other pancreatic tumours.

Because of its distinctive appearance on imaging, combined with the typical age and sex of the person affected, SPN can often be suspected with reasonable confidence before surgery, which helps guide planning. For the wider picture of cyst and growth types, see pancreatic cyst vs cancer.

1. 1

   Imaging suggests the diagnosis

   A contrast CT or MRI, combined with the typical age and sex profile, often raises SPN as the leading possibility before any tissue is taken, because of its distinctive mixed solid-and-cystic appearance.

   Endoscopic ultrasound with biopsy, to confirm

   A tissue sample confirms the diagnosis before surgery is planned, giving both the surgical and the patient the certainty needed to proceed confidently.

   Surgical removal

   Surgery is the standard, and for the great majority, the complete treatment. The extent depends on where in the pancreas the tumour sits.

   Tissue examination and follow-up

   After removal, the tumour is examined fully, and a follow-up plan is set based on those findings, since the great majority behave in a low-risk, favourable way.

The operation needed depends on exactly where the tumour sits within the pancreas — the head, body or tail — and is planned to remove it completely while preserving as much healthy pancreatic tissue and function as reasonably possible, since the people affected are often young and have decades of life ahead where pancreatic function matters. This is coordinated with our specialist HPB surgery partners, who plan the approach specifically around the tumour's location and the patient's individual anatomy.

Because the great majority of SPNs are cured by surgery alone, additional treatment such as chemotherapy is uncommonly needed, generally reserved for the small minority of cases showing more aggressive features on tissue examination or, rarely, evidence of spread beyond the pancreas.

For the great majority of people treated for SPN, surgery is curative, and long-term follow-up generally shows continued good health with no recurrence. Because SPN typically affects young women who may still be considering having children or building a career, our team takes the time to discuss what surgery means for fertility, for pancreatic function, and for daily life afterwards — questions that matter as much as the medical outcome itself.

Regular follow-up continues for a period after surgery as standard practice, and our psycho-oncology and supportive-care teams remain available throughout, recognising that a cancer-adjacent diagnosis at a young age carries its own particular emotional weight, even with a generally favourable outlook.
