Impact of circumferential resection margin on survival in ampullary cancer: retrospective analysis. BJS Open 2023; 7:zrad120. [PMID: 38155394 PMCID: PMC10754770 DOI: 10.1093/bjsopen/zrad120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 08/28/2023] [Accepted: 09/16/2023] [Indexed: 12/30/2023] Open
Abstract
BACKGROUND Ampullary carcinoma is a clinically variable entity. This study aimed to evaluate prognostic factors for the outcome of resected ampullary carcinoma patients with particular intent to analyse the influence of surgical radicality. METHODS Patients undergoing resection between 2002 and 2017 were analysed. Clinicopathological parameters, perioperative outcome and survival were examined. Risk factor analysis for postresection survival was performed. Resection margin status was evaluated according to the revised classification for pancreatic adenocarcinoma. RESULTS A total of 234 patients were identified, 97.9 per cent (n = 229) underwent formal resection, while 2.1 per cent (n = 5) underwent ampullary resection. Histological subtypes were 46.6 per cent (n = 109) pancreatobiliary, 34.2 per cent (n = 80) intestinal, 11.5 per cent (n = 27) mixed, and 7.7 per cent (n = 18) undetermined. In the pancreatobiliary group, tumours were more advanced with more vascular resections, pT4 stage, G3 differentiation and pN+ status. Five-year overall survival was significantly different for pancreatobiliary compared to intestinal (51.7 per cent versus 72.8 per cent, P = 0.0087). In univariable analysis, age, pT4 stage, pN+, pancreatobiliary subtype and positive resection margin were significantly associated with worse overall survival. Long-term outcome was significantly better after true R0 resection (circumferential resection margin-, tumour clearance >1 mm) compared with circumferential resection margin+ (<1 mm) and R1 resections (5-year overall survival: 69.6 per cent, median overall survival 191 months versus 42.4 per cent and 53 months; P = 0.0017). CONCLUSION Postresection survival of ampullary carcinoma patients is determined by histological subtype and surgical radicality. Intestinal differentiation is associated with less advanced tumour stages and better differentiation, which is reflected in a significantly better overall survival compared to pancreatobiliary differentiation. Despite this, true R0-resection is a prognostic key determinant in both entities, achieving 5-year survival in two-thirds of patients.

Li X, Chen L, Li J. Comparing the predictive performance of different lymph node staging systems for postoperative overall survival in patients with ampullary carcinoma. Front Surg 2023; 10:1002411. [PMID: 36923383 PMCID: PMC10008877 DOI: 10.3389/fsurg.2023.1002411] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 01/10/2023] [Indexed: 03/01/2023] Open
Abstract
Aim This study was to analyze and compare the predictive performance of the 7th and the 8th edition American Joint Committee on Cancer (AJCC) N staging system, lymph nodes ratio (LNR) and log odds of positive lymph node (LODDS) for the survival of patients with ampullary carcinomas (ACs). Method This retrospective cohort study included patients with primary ACs after surgery from the Surveillance, Epidemiology, and End Results (SEER) 2004-2015. Univariate and multivariate Cox proportional hazard models were used. The study population was divided into a training set and a testing set in a ratio of 7-3. The C-index and area under the curve (AUC) were used to compare the predictive performance of the four staging on overall survival (OS) in the training set and the testing set. Results A total of 7,480 patients with primary ACs (1,178 survived and 1,128 dead) were in this study. The average follow-up time was 41.1 months. N1 stage and N2 stage of the 8th edition AJCC N staging system, LNR staging (0-0.3), LNR (>0.3), LODDS (-2.4 to -0.8) and LODDS (>-0.8) were associated with OS in AC patients after adjusting for age, race, pT stage, tumor size, grade, radiation, and insurance. The C-index of the 7th AJCC N staging was significantly lower than the C-index of the 8th AJCC N staging in the training set [0.608 vs. 0.629, P < 0.001] and testing set [0.635 vs. 0.658, P < 0.001]. The C-index of the LODDS staging was significantly higher than the C-index of the 8th AJCC N staging in the training set [0.641 vs. 0.629, P = 0.034] and testing set [0.671 vs. 0.658, P = 0.034]. LODDS staging may be a potential predictor of OS at 6 months [AUC = 0.687], 12 months (AUC = 0.692), and 48 months (AUC = 0.709), and LNR staging (AUC = 0.655) may be a potential predictor of OS at 24 months in AC patients. The predictive ability of LNR staging and LODDS staging were also found in different subgroups. Conclusion The LNR and LODDS staging systems' predictive performance for OS of AC patients were superior to the 8th edition AJCC N staging system, especially in patients ages ≥65 or with higher tumor grade (grade II and III). The LNR staging and the LODDS staging were potential predictors for 24-month OS, and 6, 12, 24 and 48-month OS, respectively.

Impact of Diabetes on Short-Term and Long-Term Outcomes of Ampullary Adenocarcinoma Patients after Curative Pancreatoduodenectomy. Curr Oncol 2022; 29:6724-6734. [PMID: 36290805 PMCID: PMC9600143 DOI: 10.3390/curroncol29100528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 09/07/2022] [Accepted: 09/14/2022] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND Many studies have confirmed that diabetes was associated with prognosis in many malignant cancer types. However, the impact of diabetes on ampullary carcinoma (AC) has not been investigated. METHODS A total of 266 AC patients in the National Cancer Center of China between January 1998 and December 2020 were retrospectively reviewed. The postoperative complication rate, postoperative recurrence rate, and long-term survival were compared between the diabetes group and the no diabetes group. RESULTS A total of 32 AC patients (12.03%) were diagnosed with diabetes before surgery. In total, 111 patients (41.73%) had one or more postoperative complications, and there was no perioperative death. There was no statistically significant difference regarding postoperative complications between the diabetes group and the no diabetes group. Altogether, 120 patients (45.11%) experienced postoperative recurrence. Multivariate analysis revealed that diabetes was an independent risk factor for the recurrence (OR: 2.384, 95% CI: 1.065-5.336, p = 0.035), OS (HR: 1.597, 95% CI: 1.005-2.537, p = 0.047), and RFS (HR: 1.768, 95% CI: 1.068-2.925, p = 0.027) in AC patients after curative pancreatoduodenectomy. CONCLUSIONS Diabetes may adversely affect the recurrence of patients with AC after curative pancreaticoduodenectomy, leading to an increased risk of poor prognosis in early-stage patients. Further studies involving a large sample size are needed to validate our results.

Long-term survival and pattern of recurrence in ampullary adenocarcinoma patients after curative Whipple's resection: a retrospective cohort study in the National Cancer Center in China. Am J Cancer Res 2022; 12:4062-4073. [PMID: 36119819 PMCID: PMC9442013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Accepted: 08/07/2022] [Indexed: 06/15/2023] Open
Abstract
Due to the low incidence of ampullary adenocarcinoma (AA), the recurrence patterns, risk factors for recurrence and post-recurrence treatment are still debated. The purpose of this study is to clarify such clinical issues based on the retrospective data at the National Cancer Center in China. Finally, one hundred and eighty-two AA patients after curative Whipple's resection from 1998 to 2019 were retrospectively reviewed. Among them, 27 patients had locoregional recurrence and 61 patients had systemic recurrence. However, no significant difference of clinicopathological features and survival were found between locoregional recurrence and distant metastasis. In the recurrence group, the 1-year, 2-year, and 3-year recurrence-free survival and overall survival were 59.1%, 29.5%, 10.2%, 88.6%, 61.6%, and 37.6%, respectively. AA patients with recurrence have a worse prognosis than those without recurrence, regardless of stage. In addition, we found that advanced T stage and lymphovascular invasion were two independent risk factors for RFS in AA patients after curative Whipple's resection. In conclusion, AA patients with recurrence have a poor prognosis. Advanced T stage and lymphovascular invasion were two independent risk factors for recurrence-free survival in AA patients after curative Whipple's resection. Nevertheless, further studies with larger sample sizes are needed to fully validate.
