Large pancreatic cysts flagged for surgical consultation may not need the referral.

Follow-up of 35 patients with serous cystadenomas over 32 months found no malignant transformation and no association between initial lesion size and subsequent growth rate. Both large (>4 cm) and small SCAs grew equally, challenging the ACR recommendation for surgical consultation in large asymptomatic SCAs.

Key Findings

  • No malignant transformation in 32-month follow-up
  • Initial SCA size did not predict growth rate
  • Large and small SCAs grew equally
  • ACR's large-SCA surgical consultation recommendation may be overly aggressive

Implications

Conservative management may be safe for typical asymptomatic SCAs regardless of size, reducing unnecessary referrals.

Caveats

Very small cohort (n=35); single-center retrospective; abstract-only. Short follow-up may miss late events.
