Abstract
OBJECTIVE In the treatment of resectable pancreatic cancer, adjuvant chemotherapy is viewed as essential. However, it is yet unclear how well adjuvant chemotherapy works at different illness stages. This study aims to investigate the efficacy of adjuvant chemotherapy in various pancreatic cancer stages. MATERIALS AND METHODS Patients with pancreatic cancer who underwent surgical intervention at Sun Yat-sen University Cancer Center between January 2018 and January 2021 were included in this retrospective analysis. RESULTS 168 patients were divided into two groups: the group receiving adjuvant chemotherapy (AC) and the group receiving independent surgery (no-AC). Survival analysis reveals that among stage I patients, the AC group demonstrates significant superiority over the no-AC group in terms of recurrence-free survival (RFS) and overall survival (OS) (P = 0.0028; P = 0.022). While there was no discernible difference in RFS between the AC and no-AC groups for patients with stage II illness (P = 0.69), the AC group significantly outperformed the no-AC group in terms of OS (P = 0.047). There was no discernible difference in RFS or OS between the AC and no-AC groups for patients with stage III pancreatic cancer (P = 0.40 and P = 0.20, respectively). CONCLUSIONS The administration of adjuvant chemotherapy has been shown to improve the prognosis of patients diagnosed with stage I and II pancreatic cancer. However, its efficacy is limited in individuals with stage III pancreatic cancer. Therefore, there is an urgent need to investigate and develop more effective therapeutic options for patients in the advanced stage.

Zhejiang Da Xue Xue Bao Yi Xue Ban 2021; 50:375-382.

Abstract
To investigate whether chemotherapy could prolong the postoperative survival time in patients with early stages pancreatic ductal adenocarcinoma (PDAC). A total of 5280 stage ⅠA -ⅡB PDAC patients diagnosed from 2010 to 2015 were selected from surveillance,epidemiology,and end results (SEER) database. Propensity score matching (PSM) analysis was adopted to reduce the baseline differences between the groups. Univariate survival analysis was conducted with the Kaplan-Meier method. Multivariate survival analysis was performed with the Cox proportional hazards model. Univariate and multivariate survival analyses showed that age, differentiation, stage, chemotherapy were independent risk factors for the survival of PDAC patients. After PSM, it is found that adjuvant chemotherapy could prolong the median overall survival time (mOS) for stage ⅠB, ⅡA and ⅡB patients. However, for stage ⅠA patients, there were no significant differences in 3-year survival rate and mOS between patients with chemotherapy (=283) and without chemotherapy (=229) (57.4% vs 55.6%, vs all >0.05). Further analyses show that among 101 patients with well differentiated PDAC and 294 patients with moderately differentiated PDAC, there were no significant differences in survival rate and mOS between patients with and without chemotherapy (all >0.05). Among 117 patients with low-differentiated + undifferentiated PDAC, 3-year survival rate and mOS in patients with chemotherapy were significantly better than those without chemotherapy (48.5% vs 34.1%, vs all <0.05). Chemotherapy regimen used currently is not beneficial for patients with moderately and well differentiated stage ⅠA PDAC, but it is an independent prognostic factor for low-differentiated + undifferentiated PDAC patients.

Abstract
Background: Chemotherapy is suggested to use in all stages of pancreatic cancer. Is it reasonable to recommend chemotherapy for all PDAC patients? It is necessary to distinguish low-risk PDAC patients underwent pancreatectomy, who may not lose survival time due to missed chemotherapy and not need to endure pain, nausea, tiredness, drowsiness, and breath shortness caused by chemotherapy. Methods: Nomograms were constructed with basis from the multivariate Cox regression analysis. X-tile software was utilized to perform risk stratification. Survival curves were used to display the effect of chemotherapy in different risk-stratification. Results: All of the significant variables were used to create the nomograms for overall survival (OS). The total risk score of each patient was calculated by summing the scores related to each variable. X-tile software was utilized to classify patients into high-risk (score >283), median-risk (197

Abstract
BACKGROUND Surgical resection remains the only potentially curative treatment for pancreatic ductal adenocarcinoma (PDAC). However, a number of patients get disease recurred in a short time post-operation. Few studies have focused on the predictors of different recurrence patterns of PDAC. OBJECTIVE To try to establish and verify a nomogram to predict recurrence free survival (RFS) in PDAC patients, and to distinguish the risk factors of local recurrence first and distant metastasis first via competing risk model. METHODS Patients who underwent radical pancreatectomy for PDAC in our center from 2010 to 2018 were reviewed retrospectively. Kaplan-Meier methods and multivariate Cox regression analyses were used to identify the clinicopathological predictors of recurrence post-operation. And then, a nomogram was constructed and validated. Competing risk regression model was used to compare the predictors between local recurrence group and distant metastasis group. RESULTS A total of 200 patients were included into the final analysis, and 153 patients got disease relapsed post-operation. CA19-9 level, vascular resection, tumor differentiation, lymph node ratio (LNR) and adjuvant chemotherapy were identified as independent risk factors for recurrence free survival (RFS) and incorporated into the nomogram. The C-index of the nomogram was 0.650. Competing risk model indicated that the status of lymph-node metastasis was significantly associated the patterns of first relapse. CONCLUSIONS Nomogram and competing risk model were constructed to quantify the risk of recurrence following surgery for PDAC. Our findings may be useful for predicting RFS and recurrence pattern in clinical work.

Evaluation of the significance of adjuvant chemotherapy in patients with stage ⅠA pancreatic ductal adenocarcinoma. Pancreatology 2021; 21:581-588. [PMID: 33579600 DOI: 10.1016/j.pan.2021.01.024] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 01/20/2021] [Accepted: 01/29/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND Although adjuvant chemotherapy is considered a standard treatment for resected pancreatic ductal adenocarcinoma (PDAC), its utility in stage ⅠA patients is unclear. We aimed to investigate the recurrence rate, surgical outcome, prognostic factors, effectiveness of adjuvant chemotherapy, and determination of groups in whom adjuvant chemotherapy is effective in patients with stage ⅠA PDAC. METHODS We retrospectively analyzed 73 patients who underwent pancreatectomy and were pathologically diagnosed with stage ⅠA PDAC between 2000 and 2018. We evaluated the relation between clinicopathological factors, recurrence rates, and outcomes such as the recurrence-free and disease-specific survival rates (RFS and DSS, respectively). RESULTS The 5-year RFS and DSS rates were 52% and 58%, respectively. In multivariate analysis, a platelet-to-lymphocyte ratio (PLR) ≥ 170, prognostic nutrition index (PNI) < 47.5, and pathological grade 2 or 3 constituted risk factors for a shorter DSS (hazard ratios: 4.7, 4.6, and 4.1, respectively). Patients with 0-1 of these risk factors (low-risk group; n = 47) had significantly higher 5-year DSS rates than those with 2-3 risk factors (high-risk group; n = 26) (80% vs. 23%; P < 0.001). Patients in the low-risk group showed similar 5-year RFS rates regardless of whether they received or not adjuvant chemotherapy (75% vs 70%, respectively; P = 0.49). Contrarily, high-risk patients who underwent adjuvant chemotherapy had higher 5-year RFS rates than those who did not receive adjuvant chemotherapy (32% vs 0%; P = 0.045). CONCLUSIONS In stage IA PDAC, adjuvant chemotherapy seems to be effective only in a subgroup of high-risk patients.
