Keeping the spleen during left-sided pancreatic cancer surgery

Oncological Safety of Spleen Preservation in Left Pancreatectomy for Pancreatic Ductal Adenocarcinoma (SPLENDID): Study Protocol for a Prospective Observational International Multicenter Study

Observational Academisch Medisch Centrum - Universiteit van Amsterdam (AMC-UvA) · NCT07157605

This observational study will test whether keeping the spleen during left-sided pancreatic cancer surgery is safe by checking for cancer spread to lymph nodes at the splenic hilum in adults having a left pancreatectomy.

What this trial studies

This multicenter observational project collects data from adults who undergo open or minimally invasive left-sided pancreatectomy with planned splenectomy for pancreatic ductal adenocarcinoma to determine how often lymph node metastases occur in the splenic hilum and surrounding fat. Pathology of the splenic hilum and perisplenic fat will be reviewed to quantify the frequency of nodal involvement in that region. Patients with tumor invasion or abutment of the spleen are excluded to focus on cases where spleen preservation might be technically feasible. These results will inform whether a randomized trial testing spleen preservation versus routine splenectomy is justified.

Who should consider this trial

Good fit: Adults (≥18) undergoing open or minimally invasive left-sided pancreatectomy with concomitant splenectomy for primary resectable, borderline resectable, or locally advanced pancreatic ductal adenocarcinoma without tumor involvement of the spleen.

Not a fit: Patients whose tumor directly involves or abuts the spleen, those with non-PDAC diagnoses, or patients not undergoing splenectomy are unlikely to benefit from the study's findings.

Why it matters

Potential benefit: If keeping the spleen is shown to be safe, patients could avoid spleen removal and its associated risks such as overwhelming post-splenectomy infections and possibly reduced postoperative complications.

How similar studies have performed: Small retrospective single-center series and evidence from gastric cancer surgery suggest spleen preservation can be safe, but data specific to PDAC are limited and not definitive.
