LRAMPS Versus LDP in Selected Early-stage Left-sided Pancreatic Cancer

Official title

Laparoscopic Radical Antegrade Modular Pancreatosplenectomy Versus Laparoscopic Distal Pancreatosplecnectomy in Selected Left-sided Pancreatic Cancer: a Multicenter Randomized Controlled Clinical Trial

Overview

This multicenter randomized controlled clinical trial proposed the criteria for selecting patients with early-stage left-sided pancreatic cancer and aimed to compare the perioperative and oncological outcomes of patients within the criteria who underwent laparoscopic radical antegrade modular pancreatosplenectomy versus laparoscopic distal pancreatosplenectomy.

Detailed description

Although prospective comparative studies are lacking, laparoscopic distal pancreatosplenectomy (LDP) was considered to be feasible, safe, and oncologically equivalent for treating pancreatic ductal adenocarcinoma (PDAC). However, the extent of posterior resection and the oncological safety of achieving complete N1 lymph node resection in LDP remain uncertain. Strasberg proposed radical antegrade modular pancreatosplenectomy (RAMPS) for the treatment of resectable left-sided PDAC and confirmed that this technique can achieve negative margins and satisfactory survival. Given the oncological equivalence of laparoscopic radical antegrade modular pancreatosplenectomy (LRAMPS) and its advantages in short-term outcomes, several studies have assessed the feasibility of LRAMPS as the standard treatment for resectable left-sided PDAC. However, previous studies on LRAMPS have mostly included tumors staged T2 and above, and there is currently no research on the routine use of LRAMPS for early-stage tumors. We proposed the criteria for selecting patients with early-stage left-sided PDAC: (1) diameter ≤ 4 cm; (2) located ≥ 1 cm from the celiac trunk; (3) didn't invade the fascial layer behind the pancreas. This multicenter open-label randomized controlled clinical trial aims to compare the perioperative and oncological outcomes of patients within the criteria who underwent LRAMPS versus LDP.

Interventions

• Procedure LRAMPS
  For LRAMPS procedure, Gerota's fascia and perirenal fat capsule are removed, and the procedure is divided into anterior LRAMPS and posterior LRAMPS depending on whether the left adrenal gland is resected. The N1 station lymph nodes (i.e., groups 10, 11, and 18) in the body and tail of the pancreas are removed. If the tumor is located near the pancreatic body, the No. 9 lymph node group is additionally removed.
• Procedure LDP
  For LDP procedure, the dissection plane is located behind the fusion fascia. The N1 station lymph nodes (i.e., groups 10, 11, and 18) in the body and tail of the pancreas are removed. If the tumor is located near the pancreatic body, the No. 9 lymph node group is additionally removed.

Primary outcome measures

• R0 retroperitoneal margin rate [Time frame: From the date of surgery to 1 month after surgery.]
• R0 transection margin rate [Time frame: From the date of surgery to 1 month after surgery.]
• Lymph node positive rate [Time frame: From the date of surgery to 1 month after surgery.]

Secondary outcome measures (4)

• Perioperative complication rate [Time frame: Within 90 days after surgery.]
• Life quality satisfaction evaluated according to EORTC C30 scale [Time frame: Through study completion, an average of 3 year.]
• Recurrence-free survival (RFS) [Time frame: Through study completion, an average of 3 year.]
• Overall survival (OS) [Time frame: Through study completion, an average of 3 year.]
