Abstract
PURPOSE Various approaches have been reported for the resection of the nervous and lymphatic tissues around the superior mesenteric artery (SMA) during pancreaticoduodenectomy (PD) for pancreatic cancer. We developed a new procedure for circumferential lymph node dissection around the SMA to minimize local recurrence. METHODS We included 24 patients who underwent PD with circumferential lymph node dissection around the SMA (circumferential dissection) and 94 patients who underwent classical mesopancreatic dissection (classical dissection) between 2019 and 2021. The technical details of this new method are described in the figures and videos, and the clinical characteristics and outcomes of this technique were compared with those of classical dissection. RESULTS The median follow-up durations in the circumferential and classical dissection groups were 39 and 36 months, respectively. The patients' characteristics, including tumor resectability, preoperative and adjuvant chemotherapy rates, postoperative complication rates, and tumor stage, were similar between the two groups. No differences were observed in recurrence-free survival and overall survival between the two groups; however, the classical dissection group tended to have more local recurrences than the circumferential dissection group (8.3% vs. 33.3%, P = 0.168). Although no case of nodular-type recurrence after circumferential dissection was observed, 61.1% of local recurrences after classical dissection were of the nodular-type, and 36.4% were located on the left side of the SMA. CONCLUSIONS Performing circumferential lymph node dissection around the SMA during PD can be conducted safely with minimal risks of local recurrence and may enhance the completeness of local resection.

Clinical Efficacy of Neoadjuvant Chemotherapy with Gemcitabine plus S-1 for Resectable Pancreatic Ductal Adenocarcinoma Compared with Upfront Surgery. Ann Surg Oncol 2023; 30:5093-5102. [PMID: 37140750 DOI: 10.1245/s10434-023-13534-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Accepted: 04/03/2023] [Indexed: 05/05/2023]
Abstract
BACKGROUND The efficacy of neoadjuvant chemotherapy with gemcitabine plus S-1 (NAC-GS) in the prognosis of patients with resectable pancreatic ductal adenocarcinoma (PDAC) has been reported. NAC-GS is now assumed to be a standard regimen for resectable PDAC in Japan. However, the reason for this improvement in prognosis remains unclear. METHODS In 2019, we introduced NAC-GS for resectable PDAC. From 2015 to 2021, 340 patients were diagnosed with resectable PDAC (anatomical and biological [carbohydrate antigen (CA) 19-9 < 500 U/mL]) and were divided according to the treatment period (upfront surgery [UPS] group, 2015-2019, n = 241; NAC-GS group, 2019-2021, n = 80). We used "intention-to-treat" analysis to compare the clinical outcomes of NAC-GS to those of UPS. RESULTS Of the 80 patients with NAC-GS, 75 (93.8%) completed two cycles of NAC-GS, and the resection rate of the NAC-GS group was comparable to that of the UPS group (92.5 vs. 91.3%, P = 0.73). The R0 resection rate was significantly higher in the NAC-GS group than in the UPS group (91.3 vs. 82.6%, P = 0.04), even though the surgical burden was smaller. Progression-free survival tended to be better (hazard ratio [HR] = 0.70, P = 0.06), and overall survival was significantly better in the NAC-GS group than in the UPS group (HR 0.55, P = 0.02). CONCLUSIONS NAC-GS provided improvements in microscopic invasion leading to a high R0 rate and smooth administration and completion of adjuvant therapy, which might lead to an improved prognosis in patients with resectable PDAC.

Analysis of prognostic factors for borderline resectable pancreatic cancer after neoadjuvant chemotherapy: the importance of CA19-9 decrease in patients with elevated pre-chemotherapy CA19-9 levels. HPB (Oxford) 2023; 25:100-108. [PMID: 36280425 DOI: 10.1016/j.hpb.2022.09.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 07/09/2022] [Accepted: 09/28/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) is widely used to treat borderline resectable pancreatic cancer. This study aimed to evaluate the serum carbohydrate antigen (CA)19-9 response, in association with survival, after four cycles of NAC-gemcitabine plus nab-paclitaxel. METHODS From 2015 to 2018, patients with borderline resectable pancreatic cancer were treated with NAC. Patients were stratified into two groups after excluding CA19-9 non-secretor: Group L (CA19-9 ≥2 and ≤500 U/mL) and Group H (CA19-9 >500 U/mL). The CA19-9 decrease during NAC was evaluated as a response of NAC and was assessed in association with survival concomitant with other prognosis factors. RESULTS Eighty-seven patients were evaluated (Group L: n = 43, Group H: n = 44). In intention-to-treat-based analysis, Group L exhibited significantly better progression-free survival (PFS) than Group H (median PFS: 24 vs 14months). In resection cohort, no correlation was detected between the CA19-9 decrease and survival in Group L. In Group H, the CA19-9 decrease ≤80% was associated with unfavorable survival in multivariate analysis [Hazard ratio: 4.738 (P = 0.007)]. CONCLUSION In patients with pre-treatment CA19-9 >500 U/mL, the CA19-9 decrease ≤80% was strongly associated with poor survival and new strategy should be reconsidered for these patients.

Long-Term Outcome of Patients with Postoperative Refractory Diarrhea After Tailored Nerve Plexus Dissection Around the Major Visceral Arteries During Pancreatoduodenectomy for Pancreatic Cancer. World J Surg 2022; 46:1172-1182. [PMID: 35119513 DOI: 10.1007/s00268-022-06457-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/07/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND For pancreatic ductal adenocarcinoma (PDAC) surgery, extended dissection of the nerve plexus (pl) around the superior mesenteric artery (SMA) or celiac artery (CA) is sometimes necessary. This consequently results in postoperative refractory diarrhea. This study aimed to evaluate the clinical impact of extended nerve plexus dissection around major arteries on postoperative diarrhea. METHODS Patients who underwent pancreatoduodenectomy (PD) for PDAC between January 2013 and December 2016 were included. The frequency of diarrhea (defined as a condition requiring opioid antidiarrheal drug for at least 6 months after surgery) and its short- and long-term outcomes were reviewed. RESULTS Of 200 consecutive patients who underwent PD, 78 (39.0%) developed postoperative refractory diarrhea (diarrhea group), and 73 of them (93.6%) underwent hemi-circumferential or more nerve dissection for SMA or CA; both plSMA and plCA dissection were associated with diarrhea. Borderline resectable artery (BR-A) PDAC was included more in the diarrhea group (32.0% vs. 13.1%, P = 0.001); however, the local recurrence rate in the diarrhea group was significantly lower than that in the non-diarrhea group (14.1% vs. 26.2%, P = 0.036). The completion of adjuvant chemotherapy and overall survival were comparable between the two groups. The pre-albumin level improved in 2 years, and 61.3% of patients with diarrhea could stop opioid antidiarrheal drugs within 3 years of surgery. CONCLUSIONS Although the frequency of diarrhea increased following nerve plexus dissection around arteries, diarrhea was controllable and resulted in a reduced local recurrence rate. Aggressive dissection of the nerve plexus may be justified for local disease control in BR-A PDAC.
