Abstract
Historically, locally advanced pancreatic adenocarcinoma (LAPDAC) was considered a palliative condition. Advances in treatment have resulted in studies reporting survival after neoadjuvant treatment and surgery similar to earlier disease stages. However, there is no consensus on optimal LAPDAC management. Our aim was a systematic review of published evidence on LAPDAC treatment strategies with curative intent. Twenty-eight studies defining LAPDAC as per established criteria and reporting outcomes after neoadjuvant treatment with a view to resection were included. Primary outcomes were resection rate and proportion of curative resections. Secondary outcomes were postoperative mortality, progression-free survival, and overall survival. Neoadjuvant treatment varied significantly, most common being the combination of folinic acid, fluorouracil, irontecan, and oxaliplatin. Median percentage of patients proceeding to surgery after completion of neoadjuvant pathway was 33.5%. Median resection rate was 25%. Median R0 resection was 80% of resected patients. These outcomes ranged 0% to 100% across studies. Ninety-day postoperative mortality ranged from 0% to 5%. Median progression-free and overall survival for resected patients were 12.9 and 30 months, respectively, versus 13.2 months overall survival for unresected patients. In conclusion, although there is wide variability in reported LAPDAC resection rates post-neoadjuvant chemotherapy, retrospective data suggest that neoadjuvant treatment followed by surgery results in improved survival.

ANZ J Surg 2018; 89:481-487. [PMID: 30117669 DOI: 10.1111/ans.14764] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2018] [Revised: 05/27/2018] [Accepted: 06/04/2018] [Indexed: 12/14/2022]
Abstract
BACKGROUND This systematic review aimed to determine the accuracy of imaging modalities to predict resectability and R0 resection for borderline resectable (BRPC) or locally advanced pancreatic cancer (LAPC) after neoadjuvant therapy (NAT). METHODS A systematic search of major databases was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS Fifteen studies identified 995 patients of which 683 had BRPC and 312 LAPC. Computed tomography (CT) scan was the most common modality for re-staging (n = 14), followed by positron emission tomography (PET)-CT (n = 3) and endosonography (EUS) (n = 2). Stable disease on RECIST criteria was found in 67% of patients (range 53-80%) with 20% demonstrating reduction in tumour size. A total of 60% of patients underwent surgery post-NAT (range 31-85%) with a R0 rate of 88% (range 57-100%). Accuracy for predicting R0 resectability and T-stage on CT scan was 71 and 49%. A reduction in SUVmax on PET-CT and reduction of tumour stiffness on EUS elastography positively correlated with resectability. CONCLUSIONS More than half the patients undergo resection post-NAT for LAPC and BRPC. Stable, or reduction of, tumour disease may predict resectability. Reduction in tumour SUVmax on PET-CT and decreased tumour stiffness on EUS elastography may be potential markers of NAT response and resectability.

Inferior Infracolic 'Superior Mesenteric Artery First' Approach with a No-Touch Isolation Surgical Technique in Patients with a Borderline Resectable Cancer of the Pancreatic Head. Ann Surg Oncol 2016; 23:976-980. [PMID: 27600620 DOI: 10.1245/s10434-016-5542-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2016] [Indexed: 12/11/2022]
Abstract
BACKGROUND Early diagnosis of superior mesenteric artery (SMA) involvement is vital for patients with a borderline resectable cancer of the pancreatic head to achieve an R0 resection. We aimed to detect the effect of the inferior infracolic 'superior mesenteric artery first' approach with a no-touch isolation surgical technique in these patients. METHODS The data of 21 patients who were consecutively diagnosed with a borderline resectable cancer of the pancreatic head and treated with our technique between July 2014 and September 2015 were analyzed. RESULTS During the exploration, five patients were confirmed to have invasion to the SMA. Fourteen patients underwent a pancreaticoduodenectomy, and two patients underwent a total pancreatectomy due to a positive margin at the pancreatic neck on frozen sections. Ten men and six women, with a mean age of 64.1 years, were included in the study. Pathologic stage was T1, T2, and T3 in 1, 3, and 12 patients, respectively. Venous resection was performed in 8 patients, and an R0 resection was achieved in all patients (16/16). The mean intraoperative blood loss was 532 ml (range 200-1800 ml). At median follow-up time after surgery (12.8 months; range 4.5-18 months), two patients had a recurrence in the liver. The 1-year survival rate was 75 %, and the 1-year tumor-free survival rate was 62.5 %. CONCLUSIONS Our technique facilitates early diagnosis of arterial involvement and the achievement of an R0 resection. This technique allows the tumor to be resected in situ, and removed en bloc, and is associated with decreased blood loss.
