Abstract
PURPOSE Pancreatic ductal adenocarcinoma (PDAC) patients with normal carbohydrate antigen (CA) 19-9 levels can have early-stage cancer or advanced cancer without elevation of CA19-9 level; estimating their malignant potential is difficult. This study investigated the clinical utility of the combined use of preoperative CA 19-9 and Duke pancreatic monoclonal antigen type 2 (DUPAN-2) levels in patients with PDAC. METHODS Patients who underwent curative-intent surgery for PDAC between November 2005 and December 2021 were investigated. Eligible patients were classified into four groups based on these two markers. Among patients with normal CA19-9 levels, those with normal and high DUPAN-2 levels were classified into normal/normal (N/N) and normal/high (N/H) groups, respectively. Among patients with high CA19-9 levels, those with normal and high DUPAN-2 levels were classified into high/normal (H/N) and high/high (H/H) groups, respectively. Survival rates were compared between the groups. RESULTS Among 521 patients, the N/N, N/H, H/N, and H/H groups accounted for 25.0%, 10.6%, 35.1%, and 29.4% of patients, respectively. The proportions of resectable PDAC in the N/N and H/N groups (71.5% and 66.7%) were significantly higher than those in the N/H and H/H groups (49.1% and 54.9%) (P < 0.01). The 5-year survival rates in the N/N, N/H, H/N, and H/H groups were 66.0%, 31.1%, 34.9%, and 29.7%, respectively; the rate in the N/N group was significantly better than those in the other three groups (P < 0.0001, P < 0.0001, and P < 0.0001, respectively). CONCLUSIONS Only patients with normal CA19-9 and DUPNA-2 values should be diagnosed with early-stage PDAC.

Abstract
OBJECTIVE This nationwide multicenter study aimed to define clinically relevant thresholds of relative serum CA19-9 response after 2 months of induction chemotherapy in patients with locally advanced pancreatic cancer (LAPC). BACKGROUND CA19-9 is seen as leading biomarker for response evaluation in patients with LAPC, but early clinically useful cut-offs are lacking. METHODS All consecutive patients with LAPC after 4 cycles (m)FOLFIRINOX or 2 cycles gemcitabine-nab-paclitaxel induction chemotherapy (±radiotherapy) with CA19-9 ≥5 U/mL at baseline were analyzed (2015-2019). The association of CA19-9 response with median OS (mOS) was evaluated for different CA19-9 cut-off points. Minimum and optimal CA19-9 response were established via log-rank test. Predictors for OS were analyzed using COX regression analysis. RESULTS Overall, 212 patients were included, of whom 42 (19.8%) underwent resection. Minimum CA19-9 response demonstrating a clinically significant median OS difference (12.7 vs. 19.6 months) was seen at ≥40% CA19-9 decrease. The optimal cutoff for CA19-9 response was ≥60% decrease (21.7 vs. 14.0 mo, P =0.021). Only for patients with elevated CA19-9 levels at baseline (n=184), CA19-9 decrease ≥60% [hazard ratio (HR)=0.59, 95% CI, 0.36-0.98, P =0.042] was independently associated with prolonged OS, as were SBRT (HR=0.42, 95% CI, 0.25-0.70; P =0.001), and resection (HR=0.25, 95% CI, 0.14-0.46, P <0.001), and duration of chemotherapy (HR=0.75, 95% CI, 0.69-0.82, P <0.001). CONCLUSIONS CA19-9 decrease of ≥60% following induction chemotherapy as optimal response cut-off in patients with LAPC is an independent predictor for OS when CA19-9 is increased at baseline. Furthermore, ≥40% is the minimum cut-off demonstrating survival benefit. These cut-offs may be used when discussing treatment strategies during early response evaluation.

Abstract
Surgical resection combined with systemic chemotherapy is the cornerstone of treatment for patients with localized pancreatic cancer. Upfront surgery is considered suboptimal in cases with extensive vascular involvement, which can be classified as either borderline resectable pancreatic cancer or locally advanced pancreatic cancer. In these patients, FOLFIRINOX or gemcitabine plus nab-paclitaxel chemotherapy is currently used as preoperative chemotherapy and is eventually combined with radiotherapy. Thus, more patients might reach 5-year overall survival. Patient selection for chemotherapy, radiotherapy and subsequent surgery is based on anatomical, biological and conditional parameters. Current guidelines and clinical practices vary considerably regarding preoperative chemotherapy and radiotherapy, response evaluation, and indications for surgery. In this Review, we provide an overview of the clinical evidence regarding disease staging, preoperative therapy, response evaluation and surgery in patients with borderline resectable pancreatic cancer or locally advanced pancreatic cancer. In addition, a clinical work-up is proposed based on the available evidence and guidelines. We identify knowledge gaps and outline a proposed research agenda.

Abstract
BACKGROUND Weight changes during neoadjuvant chemotherapy (NAC) for pancreatic cancer (PDAC) are not well studied. We hypothesized that weight loss may predict poor outcomes. METHODS Weight change from NAC initiation to pancreatectomy was grouped: gain (≥5%), stable, and loss (≥5%). Pathologic, postoperative, and survival outcomes were compared. RESULTS 95 patients were included: 31.6% lost weight, 58.9% maintained weight, and 9.5% gained weight. There were no differences in chemotherapeutic regimens. Median recurrence-free survival (RFS) and overall survival (OS) were similar between patients with stable weight and those who lost weight (RFS: 9.6vs14.0months; OS: 25.8vs26.7months). Among those who gained weight, RFS (29.5months) and OS (38.4months) were greater relative to the other weight categories. On multivariable regression, weight gain was associated with improved RFS compared to loss (HR = 0.16). CONCLUSION Most patients maintain or lose weight during NAC, and weight loss does not predict poor outcomes. Weight gain may predict improved RFS.

Abstract
PURPOSE This study aimed to assess the impact of neoadjuvant therapy (NAT) for borderline resectable or locally advanced pancreatic cancer (BR/LAPC) on the American Joint Commission on Cancer (AJCC) nodal status. METHODS The medical records of BR/LAPC patients who underwent surgery with curative intent were retrospectively reviewed. The nodal status was compared between patients who underwent upfront surgery (UFS) and those who received NAT. Moreover, clinicopathological factors and prognostic factors for overall survival were analyzed. RESULTS In all, 200 patients with BR/LAPC, 78 with UFS, and 122 with NAT were enrolled. The nodal status was significantly lower in patients after NAT than after UFS (p = 0.011). A multivariate analysis of overall survival showed that UFS (hazard ratio (HR) 1.61, p = 0.024) and N2 status (HR 2.69, p < 0.001) were independent poor prognostic factors. The median serum carbohydrate antigen (CA) 19-9 level after NAT in N2 patients was 105 U/mL, which was significantly higher than that of patients with N0 (p = 0.004) and N1 (p = 0.008) status. CONCLUSION Patients with BR/LAPC who underwent surgery after NAT had significantly lower N2 status and better prognosis than patients who underwent UFS. Elevated CA19-9 levels after NAT indicated a higher nodal status.

Abstract
PURPOSE Radioresistance in pancreatic cancer patients remains a critical obstacle to overcome. Understanding the molecular mechanisms underlying radioresistance may achieve better response to radiotherapy and thereby improving the poor treatment outcome. The aim of the present study was to elucidate the mechanisms leading to radioresistance by detailed characterization of isogenic radioresistant and radiosensitive cell lines. METHODS The human pancreatic cancer cell lines, Panc-1 and MIA PaCa-2 were repeatedly exposed to radiation to generate radioresistant (RR) isogenic cell lines. The surviving cells were expanded, and their radiosensitivity was measured using colony formation assay. Tumor growth delay after irradiation was determined in a mouse pancreatic cancer xenograft model. Gene and protein expression were analyzed using RNA sequencing and Western blot, respectively. Cell cycle distribution and apoptosis (Caspase 3/7) were measured by FACS analysis. Reactive oxygen species generation and DNA damage were analyzed by detection of CM-H2DCFDA and γH2AX staining, respectively. Transwell chamber assays were used to investigate cell migration and invasion. RESULTS The acquired radioresistance of RR cell lines was demonstrated in vitro and validated in vivo. Ingenuity pathway analysis of RNA sequencing data predicted activation of cell viability in both RR cell lines. RR cancer cell lines demonstrated greater DNA repair efficiency and lower basal and radiation-induced reactive oxygen species levels. Migration and invasion were differentially affected in RR cell lines. CONCLUSIONS Our data indicate that repeated exposure to irradiation increases the expression of genes involved in cell viability and thereby leads to radioresistance. Mechanistically, increased DNA repair capacity and reduced oxidative stress might contribute to the radioresistant phenotype.

Abstract
PURPOSE This study aimed to identify the preoperative risk factors for para-aortic lymph node (PALN) positivity, including micrometastasis, in pancreatic cancer. METHODS Medical records of patients with pancreatic cancer who underwent curative resection were retrospectively reviewed, and the relationships between preoperative risk factors and PALN positivity were identified. Clinicopathological and prognostic factors for overall survival were analyzed. Micrometastasis was investigated by immunohistochemistry. RESULTS 400 patients were enrolled. PALN positivity by hematoxylin and eosin staining, micrometastasis, and negative were found in 46 (11%), 32 (8%), and 322 (81%) patients, respectively. The median overall survival times of patients with PALN positivity, including micrometastasis, was 22.5 months. Multivariate logistic regression identified borderline or locally advanced status (p=0.037), elevated preoperative carbohydrate antigen (CA) 19-9 level (p<0.001), larger tumor size ≥30 mm (p=0.001) and larger PALN size ≥10 mm (p=0.019) as independent preoperative risk factors of PALN positivity. Multivariate overall survival analysis demonstrated borderline or locally advanced status (p=0.013), elevated preoperative CA19-9 level (p<0.001) and PALN positivity (p=0.048) were independent poor prognostic factors. CONCLUSIONS Borderline or locally advanced status, elevated preoperative CA19-9 level, and larger tumor and PALN size were risk factors for PALN positivity, and thus, they may contribute to the optimization of preoperative treatments for patients with potential PALN positivity.

Abstract
OBJECTIVE To evaluate the impact of clinical and pathological parameters, including resection margin (R) status, on survival in patients undergoing pancreatic surgery after neoadjuvant treatment for initially unresectable pancreatic ductal adenocarcinoma (PDAC). BACKGROUND Prognostic factors are well documented for patients with resectable PDAC, but have not been described in detail for patients with initially unresectable PDAC undergoing resection after neoadjuvant therapy. METHODS Prospectively collected data of consecutive patients with initially unresectable pancreatic cancer treated by neoadjuvant treatment and resection were analyzed. The R status was categorized as R0 (tumor-free margin >1 mm), R1 ≤1 mm (tumor-free margin ≤1 mm), and R1 direct (microscopic tumor infiltration at margin). Clinicopathological characteristics and outcomes were compared among these groups and tested for survival prediction. RESULTS Between January, 2006 and February, 2017, 280 patients with borderline resectable (n = 18), locally advanced (n = 190), or oligometastatic (n = 72) disease underwent tumor resection after neoadjuvant treatment. Median overall survival from the time of surgery was 25.1 months for R0 (n = 82), 15.3 months for R1 ≤1 mm (n = 99), and 16.1 months for R1 direct (n = 99), with 3-year overall survival rates of 35.0%, 20.7%, and 18.5%, respectively (P = 0.0076). The median duration of the neoadjuvant treatment period was 5.1 months. In multivariable analysis, preoperative CA 19-9 levels, lymph node status, metastasis category, and vascular involvement were all significant prognostic factors for overall survival. The R status was not an independent prognostic factor. CONCLUSIONS In patients undergoing resection after neoadjuvant therapy for initially unresectable PDAC, preoperative CA 19-9 levels, lymph node involvement, metastasis category, and vascular involvement, but not the R status, were independent prognostic factors of overall survival.

Radiographic Response of Vessel Involvement and Resectability After Neoadjuvant Chemoradiation in Patients With Locally Advanced Pancreatic Cancer. Am J Clin Oncol 2021; 43:776-783.

Abstract
OBJECTIVES Survival of patients with locally advanced pancreatic cancer (LAPC) is improved when neoadjuvant chemoradiation enables subsequent surgical resection. Here, the authors assess changes in vessel involvement as a possible indicator of resectability. METHODS Pancreatic gross tumor and all major abdominal vessels were contoured for 49 patients with unresectable LAPC before and after neoadjuvant chemoradiation. Changes were compared by paired t tests. Tumor-vessel relationships were automatically quantified using Medical Imaging Interaction Toolkit and examined for correlation with resectability and outcome. RESULTS Tumor volumes were significantly reduced by chemoradiation (41 to 33 mL, P<0.0001). Maximum circumferential vessel involvement decreased for most patients and was statistically significant for the superior mesenteric (P<0.003) and splenic veins (P<0.038). Resection was possible in some patients and correlated positively with survival (28 vs. 15 mo, r=0.40), a decrease in CA 19.9 levels (r=0.48), and reduced involvement of most vessels. Nevertheless, surgical resection with a successful detachment of tumor tissue from major vessels was also achieved in some patients who did not show improvement in radiographic vessel involvement, but rather a reduction in tumor volume and CA 19.9 levels. CONCLUSIONS The present analysis demonstrates that neoadjuvant chemoradiation can enable subsequent surgical resection in patients with LAPC. Complete resection substantially prolongs survival. Therefore, surgical exploration should be offered if vessel involvement is improved by chemoradiation and considered in radiographic unchanged vessel involvement if size and CA 19.9 levels decrease, as these factors may indicate resectable disease, too.

[PMID: 33317198 PMCID: PMC7763922 DOI: 10.3390/cancers12123703] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 11/17/2020] [Accepted: 12/04/2020] [Indexed: 12/11/2022] Open
Abstract
Simple Summary Pancreatic cancer is an aggressive disease with a high mortality rate. Radiotherapy is one treatment option within a multimodal therapy approach for patients with locally advanced, non-resectable pancreatic tumors. However, radiotherapy is only effective in about one-third of the patients. Therefore, biomarkers that can predict the response to radiotherapy are of utmost importance. Recently, microRNAs, small non-coding RNAs regulating gene expression, have come into focus as there is growing evidence that microRNAs could serve as diagnostic, predictive and prognostic biomarkers in various cancer entities, including pancreatic cancer. Moreover, their high stability in body fluids such as serum and plasma render them attractive candidates for non-invasive biomarkers. This article describes the role of microRNAs as suitable blood biomarkers and outlines an overview of radiation-induced microRNAs changes and the association with radioresistance in pancreatic cancer. Abstract Today, pancreatic cancer is the seventh leading cause of cancer-related deaths worldwide with a five-year overall survival rate of less than 7%. Only 15–20% of patients are eligible for curative intent surgery at the time of diagnosis. Therefore, neoadjuvant treatment regimens have been introduced in order to downsize the tumor by chemotherapy and radiotherapy. To further increase the efficacy of radiotherapy, novel molecular biomarkers are urgently needed to define the subgroup of pancreatic cancer patients who would benefit most from radiotherapy. MicroRNAs (miRNAs) could have the potential to serve as novel predictive and prognostic biomarkers in patients with pancreatic cancer. In the present article, the role of miRNAs as blood biomarkers, which are associated with either radioresistance or radiation-induced changes of miRNAs in pancreatic cancer, is discussed. Furthermore, the manuscript provides own data of miRNAs identified in a pancreatic cancer mouse model as well as radiation-induced miRNA changes in the plasma of tumor-bearing mice.

Cancer Chemother Pharmacol 2020; 86:731-740. [PMID: 33047181 DOI: 10.1007/s00280-020-04165-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2020] [Accepted: 10/03/2020] [Indexed: 12/27/2022]
Abstract
BACKGROUND Pancreatic cancer (PC) is a highly aggressive and refractory disease, with disappointing 5-year survival rates. Regarding the wide application of neoadjuvant treatment in patients with PC, how the post-neoadjuvant Carbohydrate antigen 19-9 (CA19-9) response could translate into a survival benefit is not clearly understood. We aimed to evaluate the correlation of the CA19-9 response with overall survival (OS) in patients with PC receiving neoadjuvant therapy. METHODS An extensive electronic search in PubMed, Embase, and the Cochrane Library was performed to identify relevant articles, from which data relevant to independent correlations of the CA19-9 response with overall survival (OS) were extracted for analysis. A random-effects model was used to calculate the pooled hazard ratios (HRs) with their corresponding 95% confidence intervals (CIs). RESULTS Altogether, 17 eligible studies were identified in the systematic review. Pooled analysis showed that CA19-9 response > 50% (HR, 0.43; 95% CI 0.29-0.56; P < 0.001) and normalization of CA19-9 (HR, 0.52; 95% CI 0.42-0.63; P < 0.001) after neoadjuvant treatment are significantly associated with promising overall survival. The results also showed that optimal CA19-9 response after neoadjuvant treatment was significantly related to a favorable prognosis (HR = 0.49, 95% CI 0.42-0.55, P < 0.001; I2 = 45.1%, P = 0.04). Subgroup analysis revealed there were no prognostic difference between CA19-9 > 50% and normalization of CA19-9 after neoadjuvant treatment (P = 0.338), but the duration of neoadjuvant chemotherapy over 4 months was significantly associated with expanded postoperative survival (P = 0.013). CONCLUSIONS Serum CA19‑9 is valuable in determining the effect of neoadjuvant treatment in patients with PC. Post-neoadjuvant CA19-9 response > 50% or CA19-9 normalization was related to a more promising overall survival, suggesting that optimal CA19-9 response may be a suitable prognostic index to guide treatment decisions.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive cancers and known for its extensive genetic heterogeneity, high therapeutic resistance, and strong variation in intrinsic radiosensitivity. To understand the molecular mechanisms underlying radioresistance, we screened the phenotypic response of 38 PDAC cell lines to ionizing radiation. Subsequent phosphoproteomic analysis of two representative sensitive and resistant lines led to the reproducible identification of 7,800 proteins and 13,000 phosphorylation sites (p-sites). Approximately 700 p-sites on 400 proteins showed abundance changes after radiation in all cell lines regardless of their phenotypic sensitivity. Apart from recapitulating known radiation response phosphorylation markers such as on proteins involved in DNA damage repair, the analysis uncovered many novel members of a radiation-responsive signaling network that was apparent only at the level of protein phosphorylation. These regulated p-sites were enriched in potential ATM substrates and in vitro kinase assays corroborated 10 of these. Comparing the proteomes and phosphoproteomes of radiosensitive and -resistant cells pointed to additional tractable radioresistance mechanisms involving apoptotic proteins. For instance, elevated NADPH quinine oxidoreductase 1 (NQO1) expression in radioresistant cells may aid in clearing harmful reactive oxygen species. Resistant cells also showed elevated phosphorylation levels of proteins involved in cytoskeleton organization including actin dynamics and focal adhesion kinase (FAK) activity and one resistant cell line showed a strong migration phenotype. Pharmacological inhibition of the kinases FAK by Defactinib and of CHEK1 by Rabusertib showed a statistically significant sensitization to radiation in radioresistant PDAC cells. Together, the presented data map a comprehensive molecular network of radiation-induced signaling, improves the understanding of radioresistance and provides avenues for developing radiotherapeutic strategies.

Abstract
BACKGROUND The clinicopathologic factors associated with the survival of patients with pancreatic ductal adenocarcinoma (PDAC) during the different phases of neoadjuvant treatment (NT)-at diagnosis, restaging, or postoperatively-remain unclear. METHODS Data of patients with PDAC who underwent pancreatic resection after NT between 2008 and 2018 were retrospectively collected. Clinicopathologic characteristics and outcomes were compared stratified by resection margin status. Three multivariable regression models (at diagnosis, restaging, and postoperatively) were constructed to assess the temporal impact of different prognostic factors on all-cause survival (ACS) and disease-free survival (DFS). RESULTS All patients were diagnosed with a nonmetastatic PDAC and were appropriate candidates for NT according to the current National Comprehensive Cancer Network guidelines. From a total of 83 patients, 57 (68.7%) had a negative resection margin >1 mm (R0), whereas 26 patients (31.3%) had a positive resection margin (R1). At diagnosis, planned procedure (P = 0.017) and CA19-9 >100 U/mL (P = 0.047) were independent prognostic factors of decreased ACS. At restaging, planned procedure (P = 0.017), FOLFIRINOX (P = 0.026), and tumor size >30 mm (P = 0.030) were independent prognostic factors for increased and decreased ACS, respectively. Postoperatively, R0 was an independent prognostic factor for improved ACS (P = 0.005) and DFS (P = 0.002), whereas adjuvant therapy (P = 0.006) was associated with increased ACS. Lymph node involvement (P = 0.019) was associated with decreased DFS. CONCLUSIONS At diagnosis, restaging, and postoperatively, different, relevant clinicopathologic factors significantly impact the survival of patients with nonmetastatic PDAC undergoing NT. An R0 resection remains the most important prognostic factor and therefore should be the primary goal of surgical treatment in the neoadjuvant setting.

Abstract
PURPOSE This study aimed to reassess the duration of neoadjuvant therapy (NAT) for patients with borderline resectable pancreatic cancer (BRPC). METHODS The medical records of patients with BRPC who received NAT before intended curative resection were retrospectively reviewed. Patient demographics, clinicopathological factors, and prognostic factors for overall survival were analyzed. The serum carbohydrate antigen (CA) 19-9 level was examined monthly during NAT. RESULTS A total of 118 patients with BRPC were enrolled. The median survival time and 5-year overall survival were 28.0 months and 31%, respectively. Three months after NAT, the CA19-9 levels were normal in 57% of the patients, and 92% underwent resection. Multivariate analysis showed that radiological partial response (hazard ratio (HR), 0.53; 95% confidence interval (CI), 0.26-0.99; p = 0.047); a normal CA19-9 level after NAT (HR, 0.30; 95% CI, 0.22-0.66; p = 0.006); and tumor resection (HR, 0.29; 95% CI, 0.13-0.67; p = 0.005) were independent predictors of better survival. The median CA19-9 level and the rate of normal CA19-9 levels before and after NAT were 256 (interquartile range (IQR), 23-1197) U/mL and 33%, and 27 (IQR, 7-176) U/mL and 57%, respectively. CONCLUSION A normal CA19-9 level after NAT was an independent predictor of better survival in patients with BRPC. A longer NAT duration might contribute to improved prognosis of patients with elevated CA19-9 levels.

Reduced and Normalized Carbohydrate Antigen 19-9 Concentrations after Neoadjuvant Chemotherapy Have Comparable Prognostic Performance in Patients with Borderline Resectable and Locally Advanced Pancreatic Cancer. J Clin Med 2020; 9:jcm9051477.

Abstract
Background: The association between optimal carbohydrate antigen (CA) 19-9 concentration after neoadjuvant chemotherapy (NACT) and prognosis has not been confirmed in patients with borderline resectable (BRPC) and locally advanced pancreatic cancer (LAPC). Methods: This retrospective study included 122 patients with BRPC and 103 with LAPC who underwent surgery after NACT between 2012 and 2019 in a tertiary referral center. Prognostic models were established based on relative difference of the CA 19-9 (RDC), with their prognostic performance compared using C-index and Akaike information criterion (AIC). Results: CA 19-9 concentrations of 37–1000 U/mL before NACT showed prognostic significance in patients with BRPC and LAPC (hazard ratio [HR]: 0.262; 95% confidence interval [CI]: 0.092–0.748; p = 0.012). Prognostic models in this subgroup showed that RDC was independently prognostic of better overall survival (HR: 0.262; 95% CI: 0.093–0.739; p = 0.011) and recurrence free survival (HR: 0.299; 95% CI: 0.140–0.642; p = 0.002). The prognostic performances of RDC (C-index: 0.653; AIC: 227.243), normalization of CA 19-9 after NACT (C-index: 0.625; AIC: 230.897) and surgery (C-index: 0.613; AIC: 233.114) showed no significant differences. Conclusion: RDC was independently associated with better prognosis after NACT in patients with BRPC or LAPC. Decreased CA19-9 after NACT was a prognostic indicator of better survival and recurrence, as was normalization of CA 19-9 after both NACT and surgery.

Abstract
OBJECTIVE To compare the survival outcomes associated with clinical and pathological response in pancreatic ductal adenocarcinoma (PDAC) patients receiving neoadjuvant chemotherapy (NAC) with FOLFIRINOX (FLX) or gemcitabine/nab-paclitaxel (GNP) followed by curative-intent pancreatectomy. BACKGROUND Newer multiagent NAC regimens have resulted in improved clinical and pathological responses in PDAC; however, the effects of these responses on survival outcomes remain unknown. METHODS Clinicopathological and survival data of PDAC patients treated at 7 academic medical centers were analyzed. Primary outcomes were overall survival (OS), local recurrence-free survival (L-RFS), and metastasis-free survival (MFS) associated with biochemical (CA 19-9 decrease ≥50% vs <50%) and pathological response (complete, pCR; partial, pPR or limited, pLR) following NAC. RESULTS Of 274 included patients, 46.4% were borderline resectable, 25.5% locally advanced, and 83.2% had pancreatic head/neck tumors. Vein resection was performed in 34.7% and 30-day mortality was 2.2%. R0 and pCR rates were 82.5% and 6%, respectively. Median, 3-year, and 5-year OS were 32 months, 46.3%, and 30.3%, respectively. OS, L-RFS, and MFS were superior in patients with marked biochemical response (CA 19-9 decrease ≥50% vs <50%; OS: 42.3 vs 24.3 months, P < 0.001; L-RFS-27.3 vs 14.1 months, P = 0.042; MFS-29.3 vs 13 months, P = 0.047) and pathological response [pCR vs pPR vs pLR: OS- not reached (NR) vs 40.3 vs 26.1 months, P < 0.001; L-RFS-NR vs 24.5 vs 21.4 months, P = 0.044; MFS-NR vs 23.7 vs 20.2 months, P = 0.017]. There was no difference in L-RFS, MFS, or OS between patients who received FLX or GNP. CONCLUSION This large, multicenter study shows that improved biochemical, pathological, and clinical responses associated with NAC FLX or GNP result in improved OS, L-RFS, and MFS in PDAC. NAC with FLX or GNP has similar survival outcomes.

Prediction of survival after left-sided pancreatic resection for adenocarcinoma: Introduction of a new prognostic score. Hepatobiliary Pancreat Dis Int 2019; 18:569-575. [PMID: 31279680 DOI: 10.1016/j.hbpd.2019.06.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2019] [Accepted: 06/17/2019] [Indexed: 02/05/2023]
Abstract
BACKGROUND Due to the clinically unapparent course the entity of left-sided pancreatic adenocarcinoma is often diagnosed at advanced stages, resulting in small numbers of patients qualifying for pancreatectomy. This study strives to develop a prognostic model for survival after left-sided pancreatic resection. METHODS A total of 54 patients were analyzed. Pre- and intra-operative predictive factors for 18-month mortality were identified with multivariable binary logistic regression analysis and compiled into a prognostic model. The applicability was evaluated by assessment of the area under the receiver operating characteristic curve (AUROC). The model was internally validated applying a randomized backwards bootstrapping analysis. RESULTS The 18-month mortality rate was 74.1% (n = 40). Mean survival was 19.1 months. A prognostic model for 18-month mortality after left sided-pancreatectomy showed an AUROC >0.800: 18-month mortality risk in% = Exp(Y) / (1 + Exp(Y)) with y= -0.927 + (1.724, if CA 19-9 elevated, otherwise 0) + (1.212 × number of intra-operative transfused packed red blood cells) + (2.771, if prior abdominal surgery, otherwise 0) - (3.612, if gastric resection, otherwise 0) This model was internally validated in 40 randomized backwards bootstrapping steps with AUROCs ranging from 0.757 to 0.971. CONCLUSIONS The 18-month mortality risk for patients after left-sided pancreatectomy for adenocarcinoma of the pancreatic body can be assessed with the number of intra-operatively transfused packed red blood cells, elevated CA 19-9 levels, additional gastric resection and prior abdominal surgeries in the patient's history.

Cachectic Body Composition and Inflammatory Markers Portend a Poor Prognosis in Patients with Locally Advanced Pancreatic Cancer Treated with Chemoradiation. Cancers (Basel) 2019; 11:cancers11111655. [PMID: 31717736 PMCID: PMC6895786 DOI: 10.3390/cancers11111655] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 10/19/2019] [Accepted: 10/24/2019] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Patients with pancreatic cancer often develop cancer cachexia, a complex multifactorial syndrome with weight loss, muscle wasting and adipose tissue depletion with systemic inflammation causing physical impairment. In patients with locally advanced pancreatic cancer (LAPC) neoadjuvant treatment is routinely performed to allow a subsequent resection. Herein, we assess body composition and laboratory markers for cancer cachexia both before and after neoadjuvant chemoradiation (CRT). METHODS Subcutaneous fat (SCF), visceral fat (VF), skeletal muscle (SM), weight and laboratory parameters were determined longitudinally in 141 LAPC patients treated with neoadjuvant CRT. Changes during CRT were statistically analyzed and correlated with outcome and Kaplan-Meier curves were plotted. Different prognostic factors linked to cachexia were assessed by uni- and multivariable cox proportional hazards models. RESULTS There was a significant decrease in weight as well as SCF, VF and SM during CRT. The laboratory parameter C-reactive protein (CRP) increased significantly, whereas there was a significant decrease in leukocyte count, hemoglobin, albumin and cholinesterase as well as in the tumor marker CA 19.9. Cachectic weight loss, sarcopenia, reductions in body compartments SCF, VF and SM, and changes in laboratory markers as well as resection affected survival in univariable analysis. In multivariable analysis, weight loss >5% (HR 2.8), reduction in SM >5% (HR 5.5), an increase in CRP (HR 2.2) or CA 19.9 (HR 1.9), and resection (HR 0.4) remained independently associated with survival, whereas classical cachexia and sarcopenia did not. Interestingly, the subgroup of patients with cachectic weight loss >5% or SM reduction >5% during CRT did not benefit from resection (median survival 12 vs. 27 months). CONCLUSIONS Persistent weight loss and muscle depletion during CRT as well as systemic inflammation after CRT impacted survival more than cachexia or sarcopenia according classical definitions.

Continued Weight Loss and Sarcopenia Predict Poor Outcomes in Locally Advanced Pancreatic Cancer Treated with Chemoradiation. Cancers (Basel) 2019; 11:cancers11050709. [PMID: 31126040 PMCID: PMC6562489 DOI: 10.3390/cancers11050709] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Revised: 05/19/2019] [Accepted: 05/21/2019] [Indexed: 12/21/2022] Open
Abstract
Background: Surgical resection offers the best chance of survival in patients with pancreatic cancer, but those with locally advanced disease (LAPC) are usually not surgical candidates. This cohort often receives either neoadjuvant chemotherapy or chemoradiation (CRT), but unintended weight loss coupled with muscle wasting (sarcopenia) can often be observed. Here, we report on the predictive value of changes in weight and muscle mass in 147 consecutive patients with LAPC treated with neoadjuvant CRT. Methods: Clinicopathologic data were obtained via a retrospective chart review. The abdominal skeletal muscle area (SMA) at the third lumbar vertebral body was determined via computer tomographic (CT) scans as a surrogate for the muscle mass and skeletal muscle index (SMI) calculated. Uni- and multi-variable statistical tests were performed to assess for impact on survival. Results: Weight loss (14.5 vs. 20.3 months; p = 0.04) and loss of muscle mass (15.1 vs. 22.2 months; p = 0.007) were associated with poor outcomes. The highest survival was observed in patients who had neither cachectic weight loss nor sarcopenia (27 months), with improved survival seen in those who ultimately received a resection (23 vs. 10 months; p < 0.001). Cox regression revealed that either continued weight loss or continued muscle wasting (SMA reduction) was predictive of poor outcomes, whereas a sarcopenic SMI was not. Conclusions: Loss of weight and lean muscle in patients with LAPC is prognostic when persistent. Therefore, both should be assessed longitudinally and considered before surgery.

New observations on the utility of CA19-9 as a biomarker in Lewis negative patients with pancreatic cancer. Pancreatology 2018; 18:971-976. [PMID: 30131287 DOI: 10.1016/j.pan.2018.08.003] [Citation(s) in RCA: 47] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2018] [Revised: 08/06/2018] [Accepted: 08/08/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND Carbohydrate antigen 19-9 (CA19-9) is the best-validated biomarker for pancreatic cancer. The National Comprehensive Cancer Network (NCCN) guideline asserts that "CA19-9 will be undetectable in Lewis antigen-negative individuals". However, reports of CA19-9 secretion and its significance in Lewis (-) patients with pancreatic cancer have been inconsistent. This study was to examine serum CA19-9 levels in patients with pancreatic cancer according to Lewis status. METHODS Patients with pancreatic cancer (1482 cases) were retrieved from a prospectively maintained database. Patients with benign pancreatic disease (210 cases) and normal subjects (315 cases) were used as controls. Lewis genotypes were examined by fucosyltransferase 3 (FUT3) sequencing. RESULTS In patients with pancreatic cancer, 8.4% of subjects were Lewis (-), but only 41.9% of Lewis (-) subjects had CA19-9 values ≤ 2 U/mL. CA19-9 was even elevated (>37 U/mL) in 27.4% of Lewis (-) patients. The area under the receiver operating characteristic (ROC) curve for CA19-9 as a diagnostic biomarker was 0.842 in Lewis (-) patients with pancreatic cancer, which is closing to that of CA19-9 applied in all of patients with pancreatic cancer (0.898). Lewis (-) status was an independent prognostic factor for shorter survival in a multivariable analysis (hazard ratio (HR), 1.30, 95% confidence interval (CI), 1.03-1.64; P = 0.028). CONCLUSIONS Not all Lewis (-) patients with pancreatic cancer are non-secretors of CA19-9. Contrary to general understanding, CA19-9 can retain its utility as a biomarker in these patients in spite of Lewis (-) genotype.

Abstract
Background The purpose of this study was to develop a nomogram to predict cancer-specific survival (CSS) in pancreatic cancer (PC). Patients and methods We used the Surveillance, Epidemiology, and End Results (SEER) database to analyze 53,028 patients diagnosed with PC from 2004 to 2014 and randomly divided them into the training (n=26,583) cohort and validation (n=26,445) cohort. Univariate and multivariate analyses were used to select independent prognostic factors. We used significant prognostic factors for constructing a nomogram based on Cox regression analyses. Validation of the nomogram was assessed by discrimination and calibration. Results According to the multivariate models of training cohort, a nomogram that combined age, race, tumor location, marital status, tumor size, TNM stage, tumor grade, and surgery was constructed for predicting CSS. The internally validated and externally validated C-indexes were 0.741 and 0.734, respectively. The calibration curves showed that the nomogram was able to predict 1-, 3-, and 5-year CSS accurately. Conclusion A nomogram effectively predicts survival in patients with PC. This prognostic model may be considered for use in clinical practice.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is currently the third most frequent form of malignancy. The role of biomarkers in the diagnostic and therapeutic strategy of cancer is constantly expanding. Translational research is already changing paradigms in tumours encompassing from early diagnosis to precision medicine in advanced disease. Nomenclature for molecular subtypes of tumours is gradually gaining acceptance and there are growing expectations it will further go from the bench to the bedside. However, the clinical relevance of biomarkers in PDAC is still far behind the relevance of biomarkers in other solid tumours. This article is part of a wider project (GALLgo) involving over forty specialists devoted to the multidisciplinary management of PDAC which concluded in recommendations based on scientific evidence. The aim of the present article is to review the diagnostic, prognostic and predictive biomarkers, either in localised or advanced disease, which have been lately subjected to study and analysis and others currently available for PDAC in order to give strength-graded recommendations linked to quality of evidence that can be used as guidelines in routine clinical practice.

Abstract
BACKGROUND Recent years have seen standardization of the anatomic definitions of pancreatic adenocarcinoma, and increasing utilization of neoadjuvant therapy (NAT). The aim of the current review was to summarize the evidence for NAT in pancreatic adenocarcinoma since 2009, when consensus criteria for resectable (R), borderline resectable (BR), and locally advanced (LA) disease were endorsed. METHODS PubMed search was undertaken along with extensive backward search of the references of published articles to identify studies utilizing NAT for pancreatic adenocarcinoma. Abstracts from ASCO-GI 2014 and 2015 were also searched. RESULTS A total of 96 studies including 5520 patients were included in the final quantitative synthesis. Pooled estimates revealed 36% grade ≥ 3 toxicities, 5% biliary complications, 21% hospitalization rate and low mortality (0%, range 0-16%) during NAT. The majority of patients (59%) had stable disease. On an intention-to-treat basis, R0-resection rates varied from 63% among R patients to 23% among LA patients. R0 rates were > 80% among all patients who were resected after NAT. Among R and BR patients who underwent resection after NAT, median OS was 30 and 27.4 months, respectively. CONCLUSIONS The current study summarizes the recent literature for NAT in pancreatic adenocarcinoma and demonstrates improving outcomes after NAT compared to those historically associated with a surgery-first approach for pancreatic adenocarcinoma.

Abstract
This study aimed to develop and validate an effective prognostic nomogram for advanced PDAC patients. We conducted a prospective multicenter cohort study involving 1,526 advanced PDAC patients from three participating hospitals in China between January 1, 2004 and December 31, 2013. Two thirds of the patients were randomly assigned to the training set (n = 1,017), and one third were assigned to the validation set (n = 509). Multivariate cox regression analysis was performed to identify significant prognostic factors for overall survival to develop the nomogram. Internal and external validation using C-index and calibration curve were conducted in the training set and validation set respectively. As results, seven independent prognostic factors were identified: age, tumor stage, tumor size, ALT (alanine aminotransferase), ALB (albumin), CA 19-9, HBV infection status, and these factors were entered into the nomogram. The proposed nomogram showed favorable discrimination and calibration both in the training set and validation set. The C-indexes of the training set and validation set were 0.720 and 0.696 respectively, which were both significantly higher than that of the staging system (C-index = 0.613, P < 0.001). In conclusion, the proposed nomogram may be served as an effective tool for prognostic evaluation of advanced PDAC.

CA19-9 Normalization During Pre-operative Treatment Predicts Longer Survival for Patients with Locally Progressed Pancreatic Cancer. J Gastrointest Surg 2016; 20:1331-42.

Abstract
BACKGROUND Compared to the widely adopted 2-4 months of pre-operative therapy for patients with borderline resectable (BR) or locally advanced (LA) pancreatic ductal adenocarcinoma (PDAC), our institution tends to administer a longer duration before considering surgical resection. Using this unique approach, the aim of this study was to determine pre-operative variables associated with survival. METHODS Records from patients with BR/LA PDAC who underwent attempt at surgical resection from 1992-2014 were reviewed. RESULTS After a median duration of 6 months of pre-operative treatment, 109 patients with BR/LA PDAC (BR 63, LA 46) were explored; 93 (85.3 %) underwent pancreatectomy. Those who received at least 6 months of pre-operative treatment had longer median overall survival (OS) than those who received less (52.8 vs. 32.1 months, P = 0.044). On multivariate analysis, pre-operative treatment duration was the strongest predictor of survival (hazard ratio (HR) 4.79, P = 0.043). However, OS was similar in those whose CA19-9 normalized regardless of whether they received more or less than 6 months of chemotherapy (71.4 vs. 101.8 months, P = 0.930). CONCLUSIONS Pre-operative CA19-9 decline can guide treatment duration in patients with BR/LA PDAC. We endorse 6 months of therapy except in those patients whose values normalize, where surgery can be considered after a shorter course.

Abstract
INTRODUCTION Carbohydrate antigen 19-9 (CA 19-9) is a tumour associated antigen. Blood levels may be elevated in benign as well as malignant conditions. Its sensitivity (70-90%) and specificity (68-91%) are inadequate for accurate diagnosis. It can be used to predict the extent of disease and outcome after resection. AIM The aim of the present study was to assess the role of CA 19-9 in predicting the resectability of the tumour in the head of pancreas. MATERIALS AND METHODS This was a prospective study which included 30 patients and study period was from May 2012 to October 2014. Data collected from all patients with carcinoma of the head of pancreas on the basis of contrast enhanced computed tomography/Magnetic resonance cholangiopancreaticography. CA 19-9 levels were measured and recorded. Patients who were medically unfit for surgery or those who didn't warrant palliative surgery were excluded from the study. During surgery the operative findings on operability were documented and tabulated against corresponding CA 19-9 levels. RESULTS Of the 30 patients who were operated, 13(43.3%) patients had operable tumours and underwent Whipple's procedure and 17(56.7%) underwent palliative bypass procedure. Of the 30, CA 19-9 levels were elevated in 9(30.0%) and were normal in 21(70.0%). Among 13(43.3%) who had operable tumours, CA 19-9 was elevated in 4(13.3) and was normal in 9(30.0%). Of the 17(56.7%) who had inoperable tumours CA 19-9 was elevated in 5(16.7%) and was normal in 12(40.0%). Among the 17 who had inoperable tumours, 8(47.1%) were diagnosed preoperatively and of them CA 19-9 levels were raised in 2(11.8%) and normal in 6(35.3%). In the group of 9(52.9%) who had inoperable tumours diagnosed intraoperatively, CA 19-9 was raised in 3(17.6%) of them and was normal in the remaining 6(35.3%) of them. CONCLUSION Based on the study findings, it can be stated that there is no significant correlation with resectability of pancreatic adenocarcinoma and CA 19-9 and it doesn't predict vascular involvement and liver metastasis.

Abstract
Pancreatic cancer is an aggressive disease with dismal prognosis. It is of paramount importance to understand the underlying etiological mechanisms and identify novel, consistent, and easy-to-apply prognostic factors for precision therapy. TUSC3 (tumor suppressor candidate 3) was identified as a potential tumor suppressor gene and previous study showed TUSC3 is decreased in pancreatic cancer at mRNA level, but its putative tumor suppressor function remains to be verified. In this study, TUSC3 expression was found to be suppressed both at mRNA and protein levels in cell line models as well as in clinical samples; decreased TUSC3 expression was associated with higher pathological TNM staging and poorer outcome. In three pairs of cell lines with different NF-κB activity, TUSC3 expression was found to be reversely correlated with NF-κB activity. TUSC3-silenced pancreatic cancer cell line exhibited enhanced potential of proliferation, migration and invasion. In an orthotopic implanted mice model, TUSC3 silenced cells exhibited more aggressive phenotype with more liver metastasis. In conclusion, the current study shows that decreased immunological TUSC3 staining is a factor prognostic of poor survival in pancreatic cancer patients and decreased TUSC3 promotes pancreatic cancer cell proliferation, invasion and metastasis. The reverse correlation between NF-κB activity and TUSC3 expression may suggest a novel regulation pattern for this molecule.
