Folate receptor-positive circulating tumor cells predict survival and recurrence patterns in patients undergoing resection for pancreatic cancer. Front Oncol 2022; 12:1012609. [PMID: 36313690 PMCID: PMC9606765 DOI: 10.3389/fonc.2022.1012609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 09/26/2022] [Indexed: 12/03/2022] Open
Abstract
Objective To evaluate the prognostic impact of folate receptor (FR)-positive circulating tumor cells (FR+ CTCs) for patients with pancreatic cancer (PC). Background Risk stratification before surgery for PC patients remains challenging as there are no reliable prognostic markers currently. FR+ CTCs, detected by ligand-targeted polymerase chain reaction (LT-PCR), have shown excellent diagnostic value for PC in our previous study and prognostic value in a variety of cancer types. Methods Peripheral blood samples from 44 consecutive patients diagnosed with PC were analyzed for FR+ CTCs. 25 patients underwent tumor resection and were assigned to the surgical group. 19 patients failed to undergo radical resection because of local advance or distant metastasis and were assigned to the non-surgical group. The impact of CTCs on relapse and survival were explored. Results For the prognostic stratification, the optimal cut-off value of CTCs analyzed by receiver operating characteristic (ROC) curve was 14.49 folate units (FU)/3 ml. High CTC levels (> 14.49 FU/3 ml) were detected in 52.0% (13/25) of the patients in the surgical group and 63.2% (12/19) in the non-surgical group. In the surgical group, median disease-free survival (DFS) for patients with high CTC levels versus low CTC levels (< 14.49 FU/3 ml) was 8.0 versus 26.0 months (P = 0.008). In multivariable analysis, CTCs were an independent risk factor for DFS (HR: 4.589, P = 0.012). Concerning the recurrence patterns, patients with high CTC levels showed a significantly frequent rate of distant and early recurrence (P = 0.017 and P = 0.011). CTC levels remained an independent predictor for both distant (OR: 8.375, P = 0.014) and early recurrence (OR: 8.412, P = 0.013) confirmed by multivariable logistic regression. However, CTCs did not predict survival in the non-surgical group (P = 0.220). Conclusion FR+ CTCs in resected PC patients could predict impaired survival and recurrence patterns after surgery. Preoperative CTC levels detected by LT-PCR may help guide treatment strategies and further studies in a larger cohort are warranted.

Prognostic Impact of Radiological Splenic Artery Involvement in Pancreatic Ductal Adenocarcinoma of the Body and Tail. Ann Surg Oncol 2022; 29:7047-7058. [PMID: 35691957 DOI: 10.1245/s10434-022-11950-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 05/08/2022] [Indexed: 12/31/2022]
Abstract
BACKGROUND Splenic artery (SpA) involvement heralds poor prognosis in pancreatic ductal adenocarcinoma (PDAC) of the body and tail but is not included in the resectability criteria. This study evaluated the prognostic impact of radiological SpA involvement in PDAC of the body and tail. METHODS Preoperative computed tomography images of patients who underwent distal pancreatectomy for resectable PDAC of the body and tail (n = 242) at our hospital between 2004 and 2018 were graded according to splenic vessel involvement status as clear, abutment, or encasement. Clinicopathological prognostic factors and overall survival (OS) and recurrence-free survival (RFS) rates were compared between the three groups. The prognostic value of radiological involvement status was assessed using Harrell's concordance statistic (C-index) and time-dependent receiver-operating characteristic curve analysis and compared with pathological findings. RESULTS The diagnostic concordance rate was 0.87 (weighted κ statistic). Prognosis worsened with progression from clear, abutment, to encasement status. SpA encasement (hazard ratio [HR] 1.97, p = 0.04) predicted poor OS in multivariate Cox hazard regression analysis. SpA abutment (HR 1.77, p = 0.017) and encasement (HR 1.86, p = 0.034) independently predicted poor RFS. Splenic vein abutment and encasement were not significant predictors of poor OS or RFS. SpA encasement without adjuvant chemotherapy had the poorest prognosis because of early distant metastasis. The prognostic value was higher for radiological SpA involvement than for pathological SpA invasion. CONCLUSIONS Radiological SpA involvement status is a meaningful and reproducible prognostic indicator that can be used preoperatively for determining the treatment strategy in PDAC of the body and tail.

Abstract
PURPOSE To investigate the impact of race/ethnicity on surgical outcomes following pancreaticoduodenectomy for pancreatic cancer. METHODS A retrospective review of patients undergoing pancreaticoduodenectomy for adenocarcinoma in the National Surgical Quality Improvement Program (NSQIP) database from 2014 to 2019. Patient and tumor characteristics and 30-day postoperative outcomes were compared. Multivariable logistic and linear regression models were conducted to investigate the relationship between race/ethnicity and surgical outcomes. RESULTS Six thousand five hundred and sixty-two patients were included (84.5% White, 7.9% Black, 3% Hispanic, 4.6% Asian). Larger proportions of Blacks had preoperative American Society of Anesthesiologists class 3 or 4. There were no significant differences in tumor characteristics or operative techniques. A smaller proportion of Asians and Hispanics received neoadjuvant chemotherapy and/or radiation than Blacks and Whites. Relative to White, the Black race was independently associated with postoperative sepsis and reoperation. Both Black and Hispanic race/ethnicity were associated with prolonged intubation and delayed gastric emptying, and minorities races/ethnicities were associated with longer length of hospital stay. Relative to White, Hispanic, and Asian race/ethnicity were independently associated with a lower likelihood of neoadjuvant therapy (NAT) receipt. CONCLUSION In ACS-NSQIP participating hospitals, non-White race/ethnicity was independently associated with adverse outcomes after pancreatic cancer resection. A possible disparity in NAT receipt may exist in Asian and Hispanic patients undergoing surgical resection.

Abstract
Background The complete resection rate of pancreatic cancer has increased because of the advent of efficacious first-line treatments for unresectable pancreatic cancer. Still, strategies regarding adjuvant therapy after neoadjuvant FOLFIRINOX treatment remain to be established. Methods Data on 144 patients with borderline resectable and locally advanced pancreatic cancer who underwent resection after neoadjuvant FOLFIRINOX between January 2013 and April 2021 were retrospectively reviewed. Results Among the study patients, 113 patients (78.5%) were diagnosed with borderline resectable pancreatic cancer and 31 patients (21.5%) were diagnosed with locally advanced pancreatic cancer. Seventy-five patients (52.1%) received radiotherapy before surgery. After radical resection, 84 patients (58.3%) received 5-fluorouracil-based adjuvant therapy and 60 patients (41.7%) received non-5-fluorouracil-based adjuvant therapy. Adjuvant therapy with 5-fluorouracil-based regimen [hazard ratio (HR), 0.43 (95% CI, 0.21–0.87); p = 0.019], preoperative assessment as locally advanced pancreatic cancer [HR, 2.87 (95% CI, 1.08–7.64); p = 0.035], positive resection margin [HR, 3.91 (95% CI, 1.71–8.94); p = 0.001], and presence of pathologic lymph node involvement [HR, 2.31 (95% CI, 1.00–5.33), p = 0.050] were associated with decreased recurrence-free survival. Adjuvant therapy with 5-fluorouracil-based regimen [HR, 0.35 (95% CI, 0.15–0.84); p = 0.018], positive resection margin [HR, 4.14 (95% CI, 1.75–9.78); p = 0.001], presence of pathologic lymph node involvement [HR, 3.36 (95% CI, 1.23–9.15); p = 0.018], poor differentiation [HR, 5.69 (95% CI, 1.76–18.36); p = 0.004], and dose reduction during adjuvant therapy [HR, 1.78 (95% CI, 1.24–24.37); p = 0.025] were associated with decreased overall survival. Conclusions The 5-fluorouracil-based adjuvant therapy seems to be the proper adjuvant therapy for patients who received neoadjuvant FOLFIRINOX for borderline resectable and locally advanced pancreatic cancer.

Does Concurrent Cholestasis Alter the Prognostic Value of Preoperatively Elevated CA19-9 Serum Levels in Patients with Pancreatic Head Adenocarcinoma? Ann Surg Oncol 2022; 29:8523-8533. [PMID: 36094690 PMCID: PMC9640457 DOI: 10.1245/s10434-022-12460-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Accepted: 08/06/2022] [Indexed: 11/28/2022]
Abstract
Background Pancreatic adenocarcinoma (PDAC) patients with preoperative carbohydrate antigen 19-9 (CA19-9) serum levels higher than 500 U/ml are classified as biologically borderline resectable (BR-B). To date, the impact of cholestasis on preoperative CA19-9 serum levels in these patients has remained unquantified. Methods Data on 3079 oncologic pancreatic resections due to PDAC that were prospectively acquired by the German Study, Documentation and Quality (StuDoQ) registry were analyzed in relation to preoperative CA19-9 and bilirubin serum values. Preoperative CA19-9 values were adjusted according to the results of a multivariable linear regression analysis of pathologic parameters, bilirubin, and CA19-9 values. Results Of 1703 PDAC patients with tumor located in the pancreatic head, 420 (24.5 %) presented with a preoperative CA19-9 level higher than 500 U/ml. Although receiver operating characteristics (ROC) analysis failed to determine exact CA19-9 cut-off values for prognostic indicators (R and N status), the T, N, and G status; the UICC stage; and the number of simultaneous vein resections increased with the level of preoperative CA19-9, independently of concurrent cholestasis. After adjustment of preoperative CA19-9 values, 18.5 % of patients initially staged as BR-B showed CA19-9 values below 500 U/ml. However, the postoperative pathologic results for these patients did not change compared with the patients who had CA19-9 levels higher than 500 U/ml after bilirubin adjustment. Conclusions In this multicenter dataset of PDAC patients, elevation of preoperative CA19-9 correlated with well-defined prognostic pathologic parameters. Bilirubin adjustment of CA19-9 is feasible but does not affect the prognostic value of CA19-9 in jaundiced patients.

Total Neoadjuvant Treatment for Pancreatic Ductal Adenocarcinoma Is Associated With Limited Lymph Node Yield but Improved Ratio. J Surg Res 2022; 280:543-550.

Abstract
INTRODUCTION The lymph node yield (LNY) and lymph node ratio (LNR) of nodal metastases following pancreatoduodenectomy (PD) have been reported as prognostic parameters in patients with pancreatic ductal adenocarcinoma (PDAC). However, they have not been compared in the setting of various neoadjuvant therapy modalities. METHODS A single institutional retrospective study identified 134 patients diagnosed with resectable, BLR- and LA-PDAC who underwent PD at Fox Chase Cancer Center between 2010 and 2019. Patients were categorized based on first-line treatment as follows: surgery first (SF), total neoadjuvant therapy (TNT), and single modality neoadjuvant therapy (SMNT). The histopathological reports of the surgical specimens were examined to obtain LNY and determine the counts of lymph nodes with metastases. Subsequently, LNR was calculated as the number of positive lymph nodes divided by the number of lymph nodes examined. RESULTS Overall, 49, 38, 27, 12, and 8 patients underwent SF approach, SMNT, incomplete TNT, induction TNT, and consolidation TNT, respectively. There was no difference in R0 resection and vascular resection between the groups (P = 0.096 and 0.794, respectively). The median counts of LNY were 22, 15, 21, 11.5, and 10, respectively (P < 0.001). The average LNR was 0.16, 0.07, 0.03, 0.02, and 0.02, respectively (P < 0.001). There were statistically significant differences in overall survival in the TNT groups (log-rank test P = 0.030). CONCLUSIONS PDAC patients who undergo the TNT modality exhibit lower LNY and improved LNR compared with the SF approach and SMNT neoadjuvant therapy groups. This is likely explained by the increased treatment response and lymph node obliteration associated with the TNT approach. Our results question the minimal requirement of 11-18 harvested lymph nodes for PD following TNT.

Abstract
Simple Summary Borderline resectable pancreatic cancer (BRPC) has been primarily indicated for neoadjuvant treatment (NAT) in the last decade. This study is the updated meta-analysis for only patients with BRPC including recent NAT regimens such as FOLFIRINOX. The OS, R0 resection rate, and node-negativity rate was improved in NAT group compared with upfront surgery. Providing high-quality evidence is important to standardize the treatment protocol and help physicians decide the appropriate pancreatic cancer treatment. Abstract Neoadjuvant treatment (NAT) followed by surgery is the primary treatment for borderline resectable pancreatic cancer (BRPC). However, there is limited high-level evidence supporting the efficacy of NAT in BRPC. PubMed was searched to identify studies that compared the survival between BRPC patients who underwent NAT and those who underwent upfront surgery (UFS). The overall survival (OS) was compared using intention-to-treat (ITT) analysis. A total of 1204 publications were identified, and 19 publications with 21 data sets (2906 patients; NAT, 1516; UFS, 1390) were analyzed. Two randomized controlled trials and two prospective studies were included. Thirteen studies performed an ITT analysis, while six presented the data of resected patients. The NAT group had significantly better OS than the UFS group in the ITT analyses (HR: 0.63, 95% CI = 0.53–0.76) and resected patients (HR: 0.68, 95% CI = 0.60–0.78). Neoadjuvant chemotherapy with gemcitabine or S-1 and FOLFIRINOX improved the survival outcomes. Among the resected patients, the R0 resection and node-negativity rates were significantly higher in the NAT group. NAT improved the OS, R0 resection rate, and node-negativity rate compared with UFS. Standardizing treatment regimens based on high-quality evidence is fundamental for developing an optimal protocol.

Abstract
INTRODUCTION Meta-analyses of randomized controlled trials (RCTs) provide the highest level of evidence but can suffer from type I (false-positive) and II (false-negative) errors, which can be estimated through trial sequential analysis (TSA) demonstrating eventual credibility of results. Aim of the study was to establish through TSA which strategy between neoadjuvant approach or upfront surgery provides best results when treating potentially resectable pancreatic adenocarcinoma. MATERIALS AND METHODS RCTs were searched until September 2021. Intention-to-treat (ITT) overall survival, resection rate, ITT R0 and N0 rates and per-protocol R0 and N0 rates were the outcomes considered. Fixed-effect model was applied. TSA assumed an alpha = 5% and a power = 80%. RESULTS Four RCTs were identified accruing 325 patients for the ITT analyses and 242 for the per-protocol analyses. Neoadjuvant did not improve survival (p = 0.167) and TSA supported that this result was underpowered, requiring additional 1514 patients to prove credibility. Neoadjuvant reduced resection rate (p = 0.044) but type I error was not avoided. Neoadjuvant credibly increased per-protocol R0 and N0 rates (p = 0.003 and p < 0.001), and TSA showed that these were true-positive findings. Neoadjuvant did not increase ITT R0 rate since randomization (p = 0.169) but TSA showed lack of power. Neoadjuvant credibly increased the ITT N0 rate (p < 0.001) and TSA supported that this was a true positive finding. CONCLUSIONS Neoadjuvant strategy credibly demonstrated superiority over upfront surgery in determine per-protocol R0 resection and N0 rates, as well as ITT N0 rate. For the remaining outcomes, TSA suggested the need of larger samples to exclude type I and II errors.

[PMID: 35998796 DOI: 10.1016/j.canlet.2022.215855] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 07/26/2022] [Accepted: 07/30/2022] [Indexed: 11/20/2022]
Abstract
Pancreatic ductal adenocarcinoma (PDAC) is a dismal disease with a 5-year survival rate of less than 10%, despite the recent advances in chemoradiotherapy. The sensitivity of the PDAC patients to chemoradiotherapy varies widely, especially to radiotherapy, suggesting the need for more elucidation of the underlying mechanisms. In this study, a novel function of the nuclear ITGA2, the alpha subunit of transmembrane collagen receptor integrin alpha-2/beta-1, regulating the DNA damage response (DDR), was identified. First, analyzing The Cancer Genome Atlas (TCGA) PDAC data set indicated that the expression status of ITGA2 was negatively correlated with the genome stability parameters. The study further demonstrated that ITGA2 specially inhibited the activity of the non-homologous end joining (NHEJ) pathway and conferred the sensitivity to radiotherapy in PDAC by restraining the recruitment of DNA-dependent protein kinase catalytic subunit (DNA-PKcs) to Ku70/80 heterodimer during DDR. Considering the overexpression of ITGA2 and its associated with the poor prognosis of PDAC patients, this study suggested that the ITGA2 expression status could be used as an indicator for radiotherapy and DNA damage reagents, and the radiotherapy in combination with the overexpression of ITGA2 might be a viable treatment strategy for the PDAC patients.

Abstract
Background Pancreatic ductal adenocarcinoma is a highly fatal malignancy. The aim was to identify preoperative factors for early mortality in up-front resectable patients following pancreatoduodenectomy (PD) and develop an early mortality risk score. Methods Patients registered in the Swedish National Registry for Pancreatic and Periampullary Cancer were included. Relevant preoperative factors (n = 21) were investigated. Early mortality was defined as death within 12 months after surgery. Based on the identified risk factor odds ratios (ORs), the Score Predicting Early Mortality (SPEM) was developed.
Results In total, 2183 PDs were performed, and 926 patients met the study criteria. The mean age was 68 (SD ± 8.8) years, and 48% were female. A total of 233 (24%) patients died within 12 months. In the multivariable analyses, age > 75 years (OR 1.7; 95% CI 1.1–2.4; p = 0.008), CRP ≥ 15 mg/L (OR 2.0; 95% CI 1.3–3.1; p = 0.001), CA 19-9 > 500 U/mL (OR 1.8; 95% CI 1.0–3.2; p = 0.040), diabetes mellitus (OR 1.40; 95% CI 1.00–2.1; p = 0.042), and active smoking (OR 1.47; 95%CI 1.00–2.00; p = 0.050) were found to be independent risk factors for early mortality. Conclusion Five independent preoperative risk factors for early mortality following PD were identified and together formed SPEM. The score might be a useful tool in establishing individualized treatment plans.

Upfront versus resection after neoadjuvant chemotherapy for pancreatic adenocarcinomas with venous contact: comparative analysis of operative and survival outcomes. Surgery 2022; 172:702-707. [PMID: 35232605 DOI: 10.1016/j.surg.2022.01.011] [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: 09/20/2021] [Revised: 12/06/2021] [Accepted: 01/11/2022] [Indexed: 10/19/2022]
Abstract
BACKGROUND Neoadjuvant treatment before resection for pancreatic adenocarcinoma having contact with the splenomesentericoportal venous axis could improve the results of extended pancreatectomies. We compared the outcomes of upfront (UR) and resection after neoadjuvant chemotherapy (NAC) for pancreatic adenocarcinoma. METHODS We retrospectively reviewed clinical data of patients who underwent pancreaticoduodenectomy with venous resection for pancreatic adenocarcinoma between January 1, 2006, and December 31, 2020. Operative, pathologic, and survival outcomes were compared between upfront and resection after neoadjuvant chemotherapy. RESULTS Of the 169 patients, 55 patients underwent preoperative chemotherapy and 114 underwent upfront. No differences were found in operative time, morbidity, and mortality between the 2 groups. At pathologic examination, patients who underwent resection after neoadjuvant chemotherapy had a significantly smaller tumor size, higher rate of R0 resection, less lymph node involvement, and a lower rate of pathologic venous invasion (P < .05). The median overall survival was 27.96 months, and the overall survival rates at 1, 3, 5, and 10 years were 82%, 39%, 22%, and 11%, respectively. Multivariate Cox analysis found neoadjuvant treatment (hazard ratio: 0.60; 95% confidence interval: 0.38-0.97; P = .03), and intraoperative transfusion (hazard ratio: 2.25; 95% confidence interval: 1.47-3.46; P = .0002) as independent prognostic factors for overall survival. A dose-dependent effect of perioperative transfusion on overall survival was found (no transfusion, = 2 red blood cells, >2 red blood cells; median overall survival 41.1 months vs 27.01 months vs 19.4 months; P = .0003). CONCLUSION Neoadjuvant chemotherapy improves the pathologic and survival outcomes of pancreaticoduodenectomy with venous resection for pancreatic adenocarcinomas. The dose-dependent effect of perioperative transfusion on overall survival warrants further investigation.

Abstract
BACKGROUND AND METHODS: Racial and socioeconomic disparities in receipt of adjuvant chemotherapy affect patients with pancreatic cancer. However, differences in receipt of neoadjuvant chemotherapy among patients undergoing resection are not well-understood. A retrospective cross-sectional cohort of patients with resected AJCC Stage I/II pancreatic ductal adenocarcinoma was identified from the National Cancer Database (2014-2017). Outcomes included receipt of neoadjuvant versus adjuvant chemotherapy, or receipt of either, defined as multimodality therapy and were assessed by univariate and multivariate analysis. RESULTS Of 19 588 patients, 5098 (26%) received neoadjuvant chemotherapy, 9624 (49.1%) received adjuvant chemotherapy only, and 4757 (24.3%) received no chemotherapy. On multivariable analysis, Black patients had lower odds of neoadjuvant chemotherapy compared to White patients (OR: 0.80, 95% CI: 0.67-0.97) but no differences in receipt of multimodality therapy (OR: 0.89, 95% CI: 0.77-1.03). Patients with Medicaid or no insurance, low educational attainment, or low median income had significantly lower odds of receiving neoadjuvant chemotherapy or multimodality therapy. CONCLUSIONS Racial and socioeconomic disparities persist in receipt of neoadjuvant and multimodality therapy in patients with resected pancreatic adenocarcinoma. DISCUSSION Policy and interventional implementations are needed to bridge the continued socioeconomic and racial disparity gap in pancreatic cancer care.

Abstract
BACKGROUND Portal vein/superior mesenteric vein (PV/SMV) resection during distal pancreatectomy (DP) is often associated with technical difficulties due to the close anatomic relationship between pancreatic head and PV/SMV. In this paper, we present our operative technique and short-term outcomes of DP combined with venous resection (DP-VR) for left-sided pancreatic cancer (PC). METHODS We reviewed 368 consecutive cases of DP for PC from January 2013 to December 2018 in our institution, and identified 41 patients (11.1%) who had undergone DP-VR. The remaining 327 DP patients (88.9%) were matched to DP-VR using propensity scores in the proportion of 1:2. Demographics, intraoperative details, postoperative complications and the pathological results were compared between the two groups. RESULTS Out of the 41 DP-VR cases, in 14 (34.1%) venous resection with primary closure was performed, while the remaining 27 (65.9%) underwent end-to-end anastomosis without graft. A propensity-score-matched analysis revealed that DP-VR caused an increased risk of postoperative bleeding (17.1% vs. 3.7%, P = 0.016) and delayed gastric emptying (9.8% vs. 1.2%, P = 0.042) compared to standard DP. Overall morbidity (46.3% vs. 36.6%, P = 0.332), postoperative pancreatic fistula (31.7% vs. 26.8%, P = 0.672), R0 resection (58.5% vs. 67.1%, P = 0.223), 30-day reoperation (2.4% vs. 3.7%, P = 0.719), and 90-day mortality (0% vs. 2.5%, P = 0.550) were comparable between the two groups. In postoperative computed tomographic scans of 34 patients (82.9%) at a 90-day follow-up, PV/SMV stenosis was suggested in two patients (5.9%). CONCLUSION Despite the higher rates of postoperative bleeding, DP-VR was found to be a feasible and safe surgery with acceptable postoperative morbidity and mortality compared to standard DP for left-sided pancreatic cancer.

Predicting pathologic venous invasion before pancreatectomy with venous resection: When does radiology tell the truth? Surgery 2022; 172:303-309. [PMID: 35074172 DOI: 10.1016/j.surg.2021.12.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 12/06/2021] [Accepted: 12/14/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Patients factors in addition to radiological characteristics could predict the presence of pathologic venous invasion in patients undergoing pancreatectomy with venous resection. METHODS We tested the predictive value of 6 radiological classification methods for predicting pathologic venous invasion-the Nakao, Ishikawa, MD Anderson, Lu, Raptopoulos, and National Comprehensive Cancer Network methods-on a cohort of 198 pancreatectomies (160 pancreaticoduodenectomies and 38 total pancreatectomies) with venous resection for pancreatic adenocarcinomas. Radiological and clinical factors determining pathologic venous invasion were identified by multivariable logistic analysis. RESULTS Pathologic venous invasion was detected in 124 patients (63.2%). The multivariable logistic regression analysis identified Lu classification (odds ratio = 1.77, 95% confidence interval =1.34-2.35; P < .0001), elevated serum CA19-9 values (odds ratio = 1.97, 95% confidence interval = 1.00-3.90; P = .04), and preoperative neoadjuvant chemotherapy (odds ratio = 0.38, 95% confidence interval = 0.18-0.79; P = .009) as independent factors associated with pathologic venous invasion. Radiological tumor-vessel contact greater than 50% of the circumference or venous wall deformity was associated with a significantly higher rate of pathological venous invasion (80% vs 52%; P < .0001), deeper (media-intima) venous invasion (47% vs 25%; P < .0001), R1 resection (58% vs 41%; P = .03), higher transfusions (84% vs 66%; P = .005), and arterial resection rates (43% vs 27%; P < .0001). Tumor-vein circumference contact of >50% and/or venous wall deformity was still associated with significantly higher rates of pathologic venous invasion, regardless of whether neoadjuvant chemotherapy was used or not and CA19-9 normalized or not under preoperative treatment. CONCLUSION Preoperative radiological detection of tumor-vein circumference contact >50% and/or venous wall deformity is associated with up to 80% of cases of pathological venous invasion. The combination of radiologic features with biological (CA19-9) and clinical (presence of preoperative chemotherapy) factors could better refine preoperatively the need for venous resection.

Abstract
BACKGROUND Standard of care for resectable pancreatic cancer is a combination of surgical resection (SR) and multiagent chemotherapy (MCT). We aim to determine whether SR or MCT is associated with superior survival for patients receiving only single-modality therapy. METHODS Patients with stage I-IIb pancreatic head adenocarcinoma who received either MCT or SR were identified in the NCDB (2013-2015). Following a piecewise approach to estimating hazards over the course of follow-up, conditional overall survival (OS) at 30, 60, and 90 days after treatment initiation was estimated using landmark analyses. RESULTS 3103 patients received MCT alone (60.3%) and 2043 underwent SR alone (39.7%). SR had an OS disadvantage at 30 (HR 3.99, 95% CI 3.12-5.11) and 60 days (HR 1.85, 95% CI 1.4-2.45), but an OS advantage after 90 days (HR 0.59, 95% CI 0.55-0.64). In a landmark analysis conditioned on 90 days survival post treatment initiation, median OS was improved for SR (17.0 vs. 12.2 months, p < 0.0001); SR improved 3-year OS by 21.3% (p < 0.05), despite patients being older (median 72 vs. 67 years, p < 0.0001) with higher Charlson-Deyo comorbidity scores (≥2: 11.2 vs. 8.6%, p = 0.006). CONCLUSION For patients with resectable pancreatic cancer, SR is associated with superior long-term survival compared to MCT.

Abstract
Although neoadjuvant therapy (Nac) is recommended for high-risk resectable pancreatic cancer (R-PDAC), evidence regarding specific regimes is scarce. This report aimed to investigate the efficacy of S-1 Nac for R-PDAC. In a multicenter phase II trial, we investigated the efficacy of Nac S-1 (an oral fluoropyrimidine agent containing tegafur, gimeracil, and oteracil potassium) in R-PDAC patients. The protocol involved two cycles of preoperative S-1 chemotherapy, followed by surgery, and four cycles of postoperative S-1 chemotherapy. Two-year progression-free survival (PFS) rates were the primary endpoint. Overall survival (OS) rates and median survival time (MST) were secondary endpoints. Forty-nine patients were eligible, and 31 patients underwent resection following Nac, as per protocol (31/49; 63.3%). Per-protocol analysis included data from 31 patients, yielding the 2-year PFS rate of 58.1%, and 2-, 3-, and 5-year OS rates of 96.8%, 54.8%, and 44.0%, respectively. MST was 49.2 months. Intention-to-treat analysis involved 49 patients, yielding the 2-year PFS rate of 40.8%, and the 2-, 3-, and 5-year OS rates of 87.8%, 46.9%, and 33.9%, respectively. MST was 35.5 months. S-1 single regimen might be an option for Nac in R-PDAC; however, the high drop-out rate (36.7%) was a limitation of this study.

Characterizing the patient experience during neoadjuvant therapy for pancreatic ductal adenocarcinoma: A qualitative study. World J Gastrointest Oncol 2022; 14:1175-1186. [PMID: 35949220 PMCID: PMC9244990 DOI: 10.4251/wjgo.v14.i6.1175] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 04/01/2022] [Accepted: 05/17/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Neoadjuvant therapy (NT) has increasingly been utilized for patients with localized pancreatic ductal adenocarcinoma (PDAC). It is the recommended approach for borderline resectable (BR) and locally advanced (LA) cancers and an increasingly utilized option for potentially resectable (PR) disease. Despite its increased use, little research has focused on patient-centered metrics among patients undergoing NT, including patient experiences, preferences, and recommendations. A better understanding of all aspects of the patient experience during NT may identify opportunities to design interventions aimed at improving quality of life; it may also facilitate the completion of NT and receipt of surgery, ultimately optimizing long-term outcomes.
AIM To understand the experience of patients initiating and receiving NT to identify opportunities to improve neoadjuvant cancer care delivery.
METHODS Semi-structured interviews of patients with localized PDAC during NT were conducted to explore their experience initiating and receiving NT. Interviews took place between August 2020 and October 2021. Due to the descriptive nature of the research, questions were open ended. Interviews were conducted over the phone, audio recorded and then transcribed. All interviews were coded by two independent researchers using NVivo 12, iteratively identifying themes until thematic saturation was achieved. An integrative approach to qualitative analysis was used, utilizing both inductive and deductive methods.
RESULTS A total of 12 patients with localized PDAC were interviewed. Patients with BR (n = 7), PR (n = 2), and LA (n = 3) cancers participated in the study. All patients indicated that choosing NT was the doctor’s recommendation, while most reported not being familiar with the concept of NT (n = 11) and that NT was presented as the only option (n = 8). Five themes describing the patient experience emerged: physical symptoms, emotional symptoms, coping mechanisms, access to care, and life factors. The most commonly cited recommendation for improving the experience of NT was improved education before and during NT (n = 7). Patients highlighted the need for more information on the rationale behind choosing NT prior to surgery, the anticipated surgery and its likelihood of surgery occurring after NT, as well as general information prior to starting NT treatment. The need for seeing different members of the healthcare team, including ancillary services was also frequently cited as a recommendation for improving the experience of NT (n = 5).
CONCLUSION This study provides a framework to allow for a better understanding of the PDAC patient experience during NT and highlights opportunities to improve quality and quantity of life outcomes.

Abstract
BACKGROUND Prognosis for patients recurred rapidly after resection of pancreatic ductal adenocarcinoma (PDAC) was extremely poor. We proposed the concept of postoperative hyper-progression disease (PO-HPD) to define recurrence within 2 months after surgery, explored the role of surgery for postoperative HPD patients and determined the predictive preoperative risk factors and genomic features of PO-HPD. METHODS 976 patients undergoing curative resection of PDAC were enrolled. Survival data of 1733 stage IV patients from the US Surveillance, Epidemiology and End Results database was also collected. Patients relapsed were grouped into 3 groups regarding of the recurrence time (within 2 months were PO-HPD, within 2 to 12 months were early recurrence (ER) and within > 12 months were late recurrence (LR)). Risk factors for PO-HPD were explored with logistic regression models. Genomic features of 113 patients were investigated using next-generation sequencing-based gene panel testing. RESULTS 718 of 976 cases relapsed, 101were PO-HPD, 418 were ER and 199 were LR. Total survival of PO-HPD was 12.5 months, shorter than that of ER (16.7 months) and LR (35.1 months), and verged on that of stage IV patients (10.6 months). Preoperative risk factors for PO-HPD included red blood cell count < 3.94*10^12/L, CA19-9 ≥ 288.6 U/mL, CA125 ≥ 22.3 U/mL and tumor size≥3.45 cm. Mutations of CEBPA, ATR and JAK1 were only identified in PO-HPD and they owned lower level of CN gain compared to others. CONCLUSIONS Prognosis of PO-HPD was extremely poor and the role of surgery for PO-HPD should be prudently assessed.

Prediction of Margin-Negative Resection of Pancreatic Ductal Adenocarcinoma Following Neoadjuvant Therapy: Diagnostic Performance of NCCN Criteria for Resection vs. CT-Determined Resectability. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2022; 29:1025-1034. [PMID: 35658103 DOI: 10.1002/jhbp.1192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 04/12/2022] [Accepted: 04/17/2022] [Indexed: 11/12/2022]
Abstract
BACKGROUND Accurate assessment of pancreatic ductal adenocarcinoma (PDAC) resectability after neoadjuvant therapy (NAT) is crucial. Recently, the NCCN introduced criteria for resection of PDAC following NAT. METHODS We analyzed 127 patients who underwent NAT and pancreatectomy for PDAC between January 2010 and March 2020. CT-determined resectability according to the NCCN guideline, and CA 19-9 level was evaluated before and after NAT. Diagnostic performance of the NCCN criteria for margin-negative (R0) resection was investigated and compared with CT alone. RESULTS R0 resection was achieved in 104 (81.9%) patients. After NAT, there were 30 (23.6%) resectable, 90 (70.9%) borderline resectable, and seven (5.5%) locally advanced tumors. Significantly decreased or stable CA 19-9 levels were noted in 114 (89.8%) patients. The sensitivity and specificity of the NCCN criteria were 87.5% (91/104) and 21.7% (5/23), respectively, which were significantly different from CT including only resectable PDAC (26.9% [28/104] and 91.3% [21/23]; p<0.001), but less prominently different from CT including resectable and borderline resectable PDAC (95.2% [99/104]; p=0.022 and 8.7% [2/23]; p=0.375). CONCLUSIONS The NCCN criteria for resection following NAT showed high sensitivity and low specificity for predicting R0 resection. It had supplementary benefit over CT alone, mainly in preventing underestimation of R0 resection.

Abstract
OBJECTIVE Given the frequent adverse events with multidrug chemotherapy, not only the survival benefit but also the feasibility of using neoadjuvant chemotherapy to treat pancreatic cancer need to be clarified. SUMMARY OF BACKGROUND DATA Although the development of multidrug chemotherapy regimens has improved the survival outcomes of patients with unresectable pancreatic cancer, the benefits of these treatments in the neo-adjuvant setting remain controversial. METHODS Patients with borderline-resectable pancreatic cancer were enrolled and randomly assigned to receive neoadjuvant chemotherapy with either FOLFIRINOX or gemcitabine with nab-paclitaxel (GEM/nab-PTX). After the completion of chemotherapy, patients underwent surgical resection when feasible. This study (NUPAT-01) was a randomized phase II trial, and the primary endpoint was the R0 resection rate. RESULTS Fifty-one patients were enrolled in this study [FOLFIRINOX (n = 26) and GEM/nab-PTX (n = 25)]. A total of 84.3% (n = 43/51) of the patients eventually underwent surgery, and R0 resection was achieved in 67.4% (n = 33/ 51) of the patients. Adverse events (grade >3) due to neoadjuvant treatment were observed in 45.1% of the patients (n = 23/51), and major surgical complications occurred in 30.0% (n = 13/43), with no mortality noted. The intention-to-treat analysis showed that the 3-year overall survival rate was 54.7%, with a median survival time of 39.4 months, and a significant difference in overall survival was not observed between the FOLFIRINOX and GEM/nab-PTX groups. CONCLUSIONS These results indicate that neoadjuvant chemotherapy with FOLFIRINOX or GEM/nab-PTX is feasible and well tolerated, achieving an R0 resection rate of 67.4%. The survival of patients was even found to be favorable in the intention-to-treat analysis.

Neoadjuvant chemotherapy with or without radiotherapy versus upfront surgery for resectable pancreatic adenocarcinoma: a meta-analysis of randomized clinical trials. ESMO Open 2022; 7:100485.

Abstract
BACKGROUND The role of neoadjuvant chemotherapy (NC) in resectable pancreatic cancer (RPC) has yet to be defined. This review aims to analyze the benefit of NC in RPC compared with upfront surgery (US) in terms of overall survival (OS) and disease-free survival (DFS). PATIENTS AND METHODS PubMed, CENTRAL (The Cochrane Library), and Embase were systematically reviewed until 3 November 2021. Abstract proceedings and virtual meeting presentations from the American Society of Clinical Oncology and the European Society of Medical Oncology conferences, reference articles of published clinical trials, and review articles were considered. Only randomized clinical trials (RCTs) comparing NC administration with or without radiotherapy previous with surgery (experimental arm) versus US followed by adjuvant chemotherapy with or without radiotherapy (control arm) for RPC were included. RESULTS A total of 1135 studies were screened. Of these, 1117 studies were primarily excluded. Of the remaining 18 studies, 5 were excluded because of no adequate trial design for this work and 7 others had no available results. Finally, 6 trials with 469 patients with pancreatic cancer randomized to NC (n = 212) or US (n = 257) were selected. Compared with US, NC significantly improved OS [hazard ratio (HR) 0.75; 95% confidence interval (CI) 0.58-0.98; P = 0.033] and DFS (HR 0.73; 95% CI 0.59-0.89; P = 0.002). While the NC approach was not significantly associated with lower resection rate [relative risk (RR) 0.92; 95% CI 0.84-1.01; P = 0.069], the R0 resection rate was significantly higher for NC than for US (RR 1.31; 95% CI 1.13-1.52; P = 0.0004). CONCLUSION This is the first meta-analysis of RCTs showing that NC improves OS for RPC compared with US followed by adjuvant therapy. Ongoing RCTs should confirm these findings with FOLFIRINOX to generalize the indication of NC.

Abstract
Background and Aim Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the standard of care in advanced pancreatic cancer. Its role in resectable disease, however, is controversial. This meta-analysis aims to ascertain the clinical outcomes of patients with resectable pancreatic cancer undergoing preoperative EUS-FNA compared to those going directly to surgery. Methods A literature search was performed from 1996 to April 2019 using MEDLINE, EMBASE, and ISI Web of Knowledge for studies comparing preoperative EUS-FNA to EUS without FNA in resectable pancreatic cancer for clinical outcomes. The primary outcome is overall survival (OS). Secondary outcomes include cancer-free survival, tumor recurrence and peritoneal carcinomatosis, and post-FNA-pancreatitis rate. Results Six retrospective studies were included. Preoperative EUS-FNA had better OS than the non-FNA group (WMD, 4.40 months [0.02 to 8.78]). Cancer-free survival did not differ significantly between the two groups (WMD, 2.08 months [-2.22 to 6.38]). EUS with FNA was not associated with increased rates of tumor recurrence or peritoneal carcinomatosis. Conclusion Preoperative EUS-FNA in resectable pancreatic cancer may be associated with significantly greater OS when compared to the non-FNA group, with no significant difference in the rates of tumor recurrence or peritoneal seeding. Important limitations of our meta-analysis include the lack of prospective controlled data, which are unlikely to emerge given feasible constraints.

Taherian M, Wang H. Critical issues in pathologic evaluation of pancreatic ductal adenocarcinoma resected after neoadjuvant treatment: a narrative review. Chin Clin Oncol 2022; 11:21. [PMID: 35726190 PMCID: PMC9524072 DOI: 10.21037/cco-21-175] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Accepted: 06/08/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND AND OBJECTIVE Preoperative neoadjuvant therapy (NAT) is increasingly used in the treatment of patients with potentially resectable pancreatic ductal adenocarcinoma (PDAC). Because NAT often induces heterogeneous tumor response and extensive fibrosis both in tumor and adjacent pancreatic tissue, pathologic assessment of posttherapy pancreatectomy specimens is challenging. A limited number of studies examined the optimal grossing and sampling methods, tumor response grading (TRG), and the prognostic value of posttherapy tumor (ypT) and lymph node (ypN) stages of treated PDAC patients. In this review, we will provide an overview of the current status and critical issues in pathologic evaluation of PDAC resected after NAT. METHODS In PubMed, Google Scholar and Web of Science, we reviewed existing English literature (published up to December 2021) highlighting the most recent ones using electronic databases and authors' experience to outline the challenging aspects and new perspectives on pathologic assessment of the treated PDAC. KEY CONTENT AND FINDINGS The recent recommendations from the Pancreatobiliary Pathology Society (PBPS) provide the much-needed guidelines for systematic and standardized pathologic evaluation and reporting of treated PDAC for optimal patient care. For treated PDAC, tumor size measured by gross and radiology is not reliable. Histologic validation of tumor size on consecutive mapping sections is recommended for accurate ypT stage. A tumor size of 1.0 cm seems to be a better cutoff for ypT2 for treated PDACs. The published data suggested that the MD Anderson Cancer Center (MDA) TRG system is easy to use, has a better interobserver agreement and better correlation with patient prognosis compared to the College of American Pathologists (CAP) and Evans grading systems and may be used as an alternative TRG system for the CAP cancer protocol. CONCLUSIONS Systemic and standardized grossing and sampling are essential for accurate pathologic evaluation and reporting for optimal care of PDAC patients who received NAT. Future studies on optimal sampling and integration of histopathology with artificial intelligence (AI), molecular and immunohistochemical markers are needed for better and personalized care of treated PDAC patients.

Abstract
Importance Neoadjuvant therapy is increasingly used in localized pancreatic carcinoma, and survival is correlated with carbohydrate antigen 19-9 (CA19-9) levels and histopathologic response following neoadjuvant therapy. With several regimens now available, the choice of chemotherapy could be best dictated by response to neoadjuvant therapy (as measured by CA19-9 levels and/or pathologic response), a strategy defined herein as adaptive dynamic therapy. Objective To evaluate the association of adaptive dynamic therapy with oncologic outcomes in patients with surgically resected pancreatic cancer. Design, Setting, and Participants This retrospective cohort study included patients with localized pancreatic cancer who were treated with either gemcitabine/nab-paclitaxel or fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) preoperatively between 2010 and 2019 at a high-volume tertiary care academic center. Participants were identified from a prospectively maintained database and had a median follow-up of 49 months. Data were analyzed from October 17 to November 24, 2020. Exposures The adaptive dynamic therapy group included 219 patients who remained on or switched to an alternative regimen as dictated by CA19-9 response and for whom the adjuvant regimen was selected based on CA19-9 and/or pathologic response. The nonadaptive dynamic therapy group included 103 patients who had their chemotherapeutic regimen selected independent of CA19-9 and/or tumoral response. Main Outcomes and Measures Prognostic implications of dynamic perioperative therapy assessed through Kaplan-Meier analysis, Cox regression, and inverse probability weighted estimators. Results A total of 322 consecutive patients (mean [SD] age, 65.1 [9] years; 162 [50%] women) were identified. The adaptive dynamic therapy group, compared with the nonadaptive dynamic therapy group, had a more pronounced median (IQR) decrease in CA19-9 levels (-80% [-92% to -56%] vs -45% [-81% to -13%]; P < .001), higher incidence of complete or near-complete tumoral response (25 [12%] vs 2 [2%]; P = .007), and lower median (IQR) number of lymph node metastasis (1 [0 to 4] vs 2 [0 to 4]; P = .046). Overall survival was significantly improved in the dynamic group compared with the nondynamic group (38.7 months [95% CI, 34.0 to 46.7 months] vs 26.5 months [95% CI, 23.5 to 32.9 months]; P = .03), and on adjusted analysis, dynamic therapy was independently associated with improved survival (hazard ratio, 0.73; 95% CI, 0.53 to 0.99; P = .04). On inverse probability weighted analysis of 320 matched patients, the average treatment effect of dynamic therapy was to increase overall survival by 11.1 months (95% CI, 1.5 to 20.7 months; P = .02). Conclusions and Relevance In this cohort study that sought to evaluate the role of adaptive dynamic therapy in localized pancreatic cancer, selecting a chemotherapeutic regimen based on response to preoperative therapy was associated with improved survival. These findings support an individualized and in vivo assessment of response to perioperative therapy in pancreatic cancer.

Abstract
Pancreatic resection still represents the only curative option for patients affected by pancreatic ductal adenocarcinoma (PDAC). However, the association with modern chemotherapy regimens is a key factor in improving the inauspicious oncological outcome. The benefit of neoadjuvant treatment (NAT) for borderline resectable/locally advanced PDAC has been demonstrated; this evidence raises the question of whether even resectable PDAC should undergo NAT rather than upfront surgery. NAT may avoid futile surgery because of undetected distant metastases or aggressive tumor biology, providing more effective systemic control of the disease, which is hampered when adjuvant chemotherapy is delayed or precluded. However, recent data show controversial results regarding the efficacy and safety of NAT in resectable PDAC compared to upfront surgery. Although several prospective studies and meta-analyses indicate better oncologic outcomes after NAT, there are some biases, such as the methodological approaches used to capture the events of interest, which could make these results hardly reproducible. For instance, per-protocol studies, considering only the postoperative outcomes, tend to overestimate the performance of NAT by excluding patients who will never be suitable for surgery due to the development of chemotoxicity or tumor progression. To draw reliable conclusions, the studies should capture the events of interest of both strategies (NAT/upfront surgery) from the time of allocation to a specific treatment in an intention-to-treat fashion. This critical review highlights the current literature data concerning the use of NAT in resectable PDAC, summarizing the results of high-quality studies and focusing on the methodological issues of the most recent pieces of evidence.

Abstract
BACKGROUND Para-aortic lymph nodes (PALN) are found in the aortocaval groove and they are staged as metastatic disease if involved by pancreatic ductal adenocarcinoma (PDAC). The data in the literature is conflicting with some studies having associated PALN involvement with poor prognosis, while others not sharing the same results. PALN resection is not included in the standard lymphadenectomy during pancreatic resections as per the International Study Group for Pancreatic Surgery and there is no consensus on the management of these cases.
AIM To investigate the prognostic significance of PALN metastases on the oncological outcomes after resection for PDAC.
METHODS This is a retrospective cohort study of data retrieved from a prospectively maintained database on consecutive patients undergoing pancreatectomies for PDAC where PALN was sampled between 2011 and 2020. Statistical comparison of the data between PALN+ and PALN- subgroups, survival analysis with the Kaplan-Meier method and risk analysis with univariable and multivariable time to event Cox regression analysis were performed, specifically assessing oncological outcomes such as median overall survival (OS) and disease-free survival (DFS).
RESULTS 81 cases had PALN sampling and 17 (21%) were positive. Pathological N stage was significantly different between PALN+ and PALN- patients (P = 0.005), while no difference was observed in any of the other characteristics. Preoperative imaging diagnosed PALN positivity in one case. OS and DFS were comparable between PALN+ and PALN- patients with lymph node positive disease (OS: 13.2 mo vs 18.8 mo, P = 0.161; DFS: 13 mo vs 16.4 mo, P = 0.179). No difference in OS or DFS was identified between PALN positive and negative patients when they received chemotherapy either in the neoadjuvant or in the adjuvant setting (OS: 23.4 mo vs 20.6 mo, P = 0.192; DFS: 23.9 mo vs 20.5 mo, P = 0.718). On the contrary, when patients did not receive chemotherapy, PALN disease had substantially shorter OS (5.5 mo vs 14.2 mo; P = 0.015) and DFS (4.4 mo vs 9.8 mo; P < 0.001). PALN involvement was not identified as an independent predictor for OS after multivariable analysis, while it was for DFS doubling the risk of recurrence.
CONCLUSION PALN involvement does not affect OS when patients complete the indicated treatment pathway for PDAC, surgery and chemotherapy, and should not be considered as a contraindication to resection.

Abstract
OBJECTIVES To investigate the accrual proportion and patients' reasons for not participating in the PREOPANC trial on neoadjuvant chemoradiotherapy versus immediate surgery in resectable and borderline resectable pancreatic cancer, and to compare these patients' outcomes with those of patients who had been randomized in the trial. SUMMARY OF BACKGROUND DATA The external validity of multicenter randomized trials in cancer treatment has been criticized for suboptimal non-representative inclusion. In trials, it is unclear how outcomes compare between randomized and nonrandomized patients. METHODS At 8 of 16 participant centers, this multicenter observational study identified validation patients, who had been eligible but not randomized during recruitment for the PREOPANC trial. We assessed the accrual proportion, investigated their most common reasons for not participating in the trial, and compared resection rates, radical (R0) resection rates, and overall survival between the validation patients and PREOPANC patients, who had been randomized in the trial to immediate surgery. RESULTS In total, 455 patients had been eligible during the recruitment period, 151 of whom (33%) had been randomized. Fifty-five percent of the 304 validation patients had refused to participate. Median overall survival in the validation group was 15.2 months, against 15.5 months in the PREOPANC group (P = 1.00). The respective resection rates (76% vs 73%) and R0 resection rates (51% vs 46%) did not differ between the groups. CONCLUSIONS The PREOPANC trial included a reasonable percentage of 33% of eligible patients. In terms of the outcomes survival, resection rate, and R0 resection rate, this appeared to be a representative group.

Abstract
OBJECTIVES To investigate the effect of preoperative chemoradiotherapy on surgical complications in patients after pancreatic resection for (borderline-)resectable pancreatic cancer. SUMMARY OF BACKGROUND DATA Preoperative chemoradiotherapy is increasingly used in patients with (borderline-)resectable pancreatic cancer. concerns have been raised about the potential harmful effect of any preoperative therapy on the surgical complication rate after pancreatic resection. METHODS An observational analysis was performed within the multicenter randomized controlled PREOPANC trial (April 2013-July 2017). The trial randomly assigned (1:1) patients to preoperative chemoradiotherapy followed by surgery and the remaining adjuvant chemotherapy or to immediate surgery, followed by adjuvant chemotherapy. The main analysis consisted of a per-protocol approach. The endpoints of the present analyses were the rate of postoperative complications. RESULTS This study included 246 patients from 16 centers, of whom 66 patients underwent resection after preoperative therapy and 98 patients after immediate surgery. No differences were found regarding major complications (37.9% vs 30.6%, P=0.400), postpancreatectomy hemorrhage (9.1% vs 5.1%, P=0.352), delayed gastric emptying (21.2% vs 22.4%, P=0.930), bile leakage (4.5% vs 3.1%, P=0.686), intra-abdominal infections (12.1% vs 10.2%, P=0.800), and mortality (3.0% vs 4.1%, P=1.000). There was a significant lower incidence of postoperative pancreatic fistula in patients who received preoperative chemoradiotherapy (0% vs 9.2%, P=0.011). CONCLUSIONS Preoperative chemoradiotherapy did not increase the incidence of surgical complications or mortality and reduced the rate of postoperative pancreatic fistula after resection in patients with (borderline-)resectable pancreatic cancer.

Abstract
The incidence of pancreatic ductal adenocarcinoma is continuously increasing and will become the second leading cause of cancer-related death in Europe and the USA by 2030. With a 5-year overall survival rate of less than 10% the prognosis remains poor. So far surgical tumor resection remains the only curative treatment option, which is now partially supported by multimodal neoadjuvant and adjuvant therapy concepts. Due to the aggressive tumor biology patients with advanced pancreatic cancer in particular can profit from these multimodal therapy concepts. Additionally, in recent years surgical treatment was optimized, the criteria for tumor resectablity were defined and minimally invasive surgery was widely introduced. This review article summarizes the newest developments and the new German S3 guidelines concerning surgery of pancreatic cancer.

Abstract
BACKGROUND Neoadjuvant therapy (NAT) is increasingly being used in the management of borderline resectable pancreatic cancer (BRPC). We compared the outcomes of patients with BRPC treated either with upfront surgery (UPS) or NAT to assess whether increased use of NAT has helped improve perioperative and long-term outcomes. METHODS Prospectively maintained database of 201 consecutive patients with BRPC treated at Tata Memorial Center, India, from 2007-2019 was analyzed. RESULTS NAT was offered to 148 patients and 53 were planned for UPS. Progression on NAT was seen in 47 (31.8%) patients. Resection was performed in 103 patients (51.24%). The resection rate was significantly lower after NAT as compared with upfront explorations (42.56% vs 75.47%, P = .00) however, R0 resection rate after NAT was significantly better (74.6% vs 42.5%, P = .001). NAT group showed a significant decrease in the pT stage (P = .004), node positivity (60%-31.7%, P = .005%), and perineural invasion (70%-41.6% P = .026). There was no significant difference in the median overall survival (OS) of patients offered NAT versus UPS on an intention-to-treat basis (15 vs 18 months P = .431). However, OS (22 vs 19 months, P = .205) and disease-free survival (DFS) (16 vs 11 months, P = .135) were higher for resected patients in the NAT group and OS was significantly superior in patients completing the course of treatment (34 vs 22 months, P = .010) CONCLUSION: The progression rate with NAT in patients with BPRC was 31.8%. NAT was associated with significant pathologic downstaging, improvement in R0 resection rate, and survival in resected patients.

Neoadjuvant Chemoradiotherapy Versus Upfront Surgery for Resectable and Borderline Resectable Pancreatic Cancer: Long-Term Results of the Dutch Randomized PREOPANC Trial. J Clin Oncol 2022; 40:1220-1230. [PMID: 35084987 DOI: 10.1200/jco.21.02233] [Citation(s) in RCA: 276] [Impact Index Per Article: 138.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 10/28/2021] [Accepted: 12/22/2021] [Indexed: 12/12/2022] Open
Abstract
PURPOSE The benefit of neoadjuvant chemoradiotherapy in resectable and borderline resectable pancreatic cancer remains controversial. Initial results of the PREOPANC trial failed to demonstrate a statistically significant overall survival (OS) benefit. The long-term results are reported. METHODS In this multicenter, phase III trial, patients with resectable and borderline resectable pancreatic cancer were randomly assigned (1:1) to neoadjuvant chemoradiotherapy or upfront surgery in 16 Dutch centers. Neoadjuvant chemoradiotherapy consisted of three cycles of gemcitabine combined with 36 Gy radiotherapy in 15 fractions during the second cycle. After restaging, patients underwent surgery followed by four cycles of adjuvant gemcitabine. Patients in the upfront surgery group underwent surgery followed by six cycles of adjuvant gemcitabine. The primary outcome was OS by intention-to-treat. No safety data were collected beyond the initial report of the trial. RESULTS Between April 24, 2013, and July 25, 2017, 246 eligible patients were randomly assigned to neoadjuvant chemoradiotherapy (n = 119) and upfront surgery (n = 127). At a median follow-up of 59 months, the OS was better in the neoadjuvant chemoradiotherapy group than in the upfront surgery group (hazard ratio, 0.73; 95% CI, 0.56 to 0.96; P = .025). Although the difference in median survival was only 1.4 months (15.7 months v 14.3 months), the 5-year OS rate was 20.5% (95% CI, 14.2 to 29.8) with neoadjuvant chemoradiotherapy and 6.5% (95% CI, 3.1 to 13.7) with upfront surgery. The effect of neoadjuvant chemoradiotherapy was consistent across the prespecified subgroups, including resectable and borderline resectable pancreatic cancer. CONCLUSION Neoadjuvant gemcitabine-based chemoradiotherapy followed by surgery and adjuvant gemcitabine improves OS compared with upfront surgery and adjuvant gemcitabine in resectable and borderline resectable pancreatic cancer.

Combined multiagent chemotherapy and radiotherapy is associated with prolonged overall survival in patients with non-operatively managed stage II-III pancreatic adenocarcinoma. HPB (Oxford) 2022; 24:433-442. [PMID: 34465529 DOI: 10.1016/j.hpb.2021.08.938] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Revised: 07/25/2021] [Accepted: 08/06/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Most patients with pancreatic adenocarcinoma (PDAC) do not undergo surgical resection. The role of radiotherapy (RT) in non-operatively managed localized pancreatic adenocarcinoma is unclear. METHODS The National Cancer Database (2010-2016) was queried for patients with clinical stage II-III PDAC treated with multiagent systemic chemotherapy (CT) +/- RT but not surgery. Factors associated with the receipt of RT and overall survival were compared after adjusting for patient demographics and clinical characteristics. RESULTS A total of 14,921 patients were included, of whom 9279 received CT and 5382 received CT + RT. Patients treated with CT + RT were more likely to be younger (65vs66yrs), treated at non-academic facilities (48.8%vs46.7%), have private insurance (40.3%vs36.5%), and have clinical T4 tumors (53.6%vs48.7%). Most patients who were treated with RT received external beam radiotherapy (89.3%), and the median dose was 5,000 cGy. Median time to start of RT was 129 days. CT + RT was associated with longer overall survival (15.9vs11.8mos,p < 0.001), and remained associated with survival on multivariable analysis (HR 0.74, 95%CI 0.70-0.78). On a 4-month conditional survival analysis, combined CT + RT remained associated with improved survival compared to CT alone (16.0vs13.1mos,p < 0.001). CONCLUSIONS In patients with non-operatively managed localized pancreatic adenocarcinoma, combined radiotherapy and multiagent systemic chemotherapy is associated with improved overall survival compared to chemotherapy alone.

Covered self-expandable metallic stent versus plastic stent for preoperative endoscopic biliary drainage in patients with pancreatic cancer: a multi-center retrospective cohort study. Scand J Gastroenterol 2022; 57:493-500.

Abstract
BACKGROUND Expanding indications for neoadjuvant chemotherapy (NAC) for resectable pancreatic cancer prolong the period from diagnosis to surgery. In resectable pancreatic cancer with malignant biliary obstruction (MBO), the biliary drainage method without any biliary events is ideally required to safely perform NAC as planned. Plastic stents (PS) have been traditionally used for preoperative biliary drainage; however, recently, covered self-expandable metallic stents (CSEMS) have emerged as a tool for preoperative biliary drainage. AIMS To compare CSEMS with PS for preoperative biliary drainage in the management of resectable pancreatic cancer with MBO. METHODS In this multicenter retrospective cohort study, we compared CSEMS with PS for preoperative biliary drainage in patients with pancreatic cancer at three tertiary care centers between 2008 and 2019. RESULTS Of the 120 enrolled patients, 45 underwent CSEMS and 75 underwent PS. No significant difference was observed in the basic characteristics between the groups. The rate of recurrent biliary obstruction (RBO) was significantly lower and the time to RBO was significantly longer in the CSEMS group. In multivariate analysis, CSEMS was an independent factor for a longer RBO. However, pancreatitis and cholecystitis were more common in the CSEMS group. The surgery-related adverse events were not significantly different between the two groups, except for longer surgery time and time to discharge in the CSEMS group. CONCLUSIONS CSEMS for preoperative endoscopic biliary drainage in patients with pancreatic cancer reduced RBO, although the risk for pancreatitis or cholecystitis could be increased.

Abstract
BACKGROUND Complete resection is the only potentially curative treatment in patients with pancreatic ductal adenocarcinoma (PDA) and is associated with a longer overall survival (OS) than incomplete resection of tumor. Hence, prediction of the resection status after surgery would help predict the prognosis of patients with PDA. PURPOSE To predict residual tumor (R) classification and OS in patients who underwent first-line surgery for PDA using preoperative magnetic resonance imaging (MRI). MATERIAL AND METHODS In this study, 210 patients with PDA who underwent MRI and first-line surgery were randomly categorized into a test group (n=150) and a validation group (n=60). The R classification was divided into R0 (no residual tumor) and R1/R2 (microscopic/macroscopic residual tumor). Preoperative MRI findings associated with R classification and OS were assessed by using logistic regression and Cox proportional hazard models. In addition, the prediction models for the R classification and OS were validated using calibration plots and C statistics. RESULTS On preoperative MRI, portal vein encasement (odds ratio 4.755) was an independent predictor for R1/R2 resection (P=0.040). Tumor size measured on MRI (hazard ratio [HR] per centimeter 1.539) was a predictor of OS, along with pathologic N1 and N2 stage (HR 1.944 and 3.243, respectively), R1/R2 resection (HR 3.273), and adjuvant chemoradiation therapy (HR 0.250) (P<0.050). Calibration plots demonstrated satisfactory predictive performance. CONCLUSION Preoperative MRI was valuable for predicting R1/R2 resection using portal vein encasement. Tumor size measured on MRI was useful for the prediction of OS after first-line surgery for PDA.

Abstract
BACKGROUND This study aimed to identify predictors for early and very early disease recurrence in patients undergoing resection of pancreatic ductal adenocarcinoma (PDAC) resection with and without neoadjuvant therapy. METHODS Included were patients who underwent PDAC resection (2014-2016). Multivariable multinomial regression was performed to identify preoperative predictors for manifestation of recurrence within 3, 6 and 12 months after PDAC resection. RESULTS 836 patients with a median follow-up of 37 (interquartile range [IQR] 30-48) months and overall survival of 18 (IQR 10-32) months were analyzed. 670 patients (80%) developed recurrence: 82 patients (10%) <3 months, 96 patients (11%) within 3-6 months and 226 patients (27%) within 6-12 months. LogCA 19-9 (OR 1.25 [95% CI 1.10-1.41]; P < 0.001) and neoadjuvant treatment (OR 0.09 [95% CI 0.01-0.68]; P = 0.02) were associated with recurrence <3 months. LogCA 19-9 (OR 1.23 [95% CI 1.10-1.38]; P < 0.001) and 0-90° venous involvement on CT imaging (OR 2.93 [95% CI 1.60-5.37]; P < 0.001) were associated with recurrence within 3-6 months. A Charlson Age Comorbidity Index ≥4 (OR 1.53 [95% CI 1.09-2.16]; P = 0.02) and logCA 19-9 (OR 1.24 [95% CI 1.14-1.35]; P < 0.001) were related to recurrence within 6-12 months. CONCLUSION This study demonstrates preoperative predictors that are associated with the manifestation of early and very early recurrence after PDAC resection. Knowledge of these predictors can be used to guide individualized surveillance and treatment strategies.

Abstract
Patients affected by pancreatic ductal adenocarcinoma (PDAC) have very poor prognosis, whereby at a follow-up of 5 years, the mortality rate is very similar to the incidence rate. Globally, around 10% of patients are amenable to radical surgery at the time of diagnosis, which represents the only chance of cure or long-term survival for these patients. Almost 40% of patients with PDAC show locally advanced pancreatic cancer (LAPC). LAPC is not a metastatic disease, although it is not amenable to radical surgery. For these patients, systemic induction chemotherapy with intravenous FOLFIRINOX (5-fluorouracil, folic acid, irinotecan, oxaliplatin) regimen is administered, with the aim of conversion to surgery, although the conversion rate remains low, at approximately 10% to 15%. Pancreatic arterial chemotherapy has been explored to overcome the intrinsic tumor pancreatic resistance to systemic chemotherapy, where an intra-arterial port-a-cath is placed by means of interventional oncology techniques under angiographic guidance in the operating theater. Here, we treated a patient with an intra-arterially modified FOLFIRINOX regimen. Three courses were administered, and the patient experienced no adverse events. At the end of the third course, the patient rapidly developed lung failure due to nosocomial Legionella pneumophila infection, despite the impressive pathological tumor response shown in the autopsy report. This is a first and unique report that demonstrates that pancreatic intra-arterial FOLFIRINOX can be safe and efficacious. We believe that this preliminary result will be confirmed in the next patients to be enrolled and that it provides a glimmer of hope for patients with this lethal disease.

BIOSENSORS 2022; 12:206. [PMID: 35448266 PMCID: PMC9028387 DOI: 10.3390/bios12040206] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 03/23/2022] [Accepted: 03/28/2022] [Indexed: 05/12/2023]
Abstract
While patients with resectable pancreatic ductal adenocarcinoma (PDAC) show improved survival compared to their non-resectable counterparts, survival remains low owing to occult metastatic disease and treatment resistance. Liquid biopsy based on circulating tumor cells (CTCs) and cell-free DNA (cfDNA) has been shown to predict recurrence and treatment resistance in various types of cancers, but their utility has not been fully demonstrated in resectable PDAC. We have simultaneously tracked three circulating biomarkers, including CTCs, cfDNA, and circulating tumor DNA (ctDNA), over a period of cancer treatment using a microfluidic device and droplet digital PCR (ddPCR). The microfluidic device is based on the combination of filtration and immunoaffinity mechanisms. We have measured CTCs, cfDNA, and ctDNA in a cohort of seven resectable PDAC patients undergoing neoadjuvant therapy followed by surgery, and each patient was followed up to 10 time points over a period of 4 months. CTCs were detectable in all patients (100%) at some point during treatment but were detectable in only three out of six patients (50%) prior to the start of treatment. Median cfDNA concentrations remained comparable to negative controls throughout treatment. ddPCR was able to find KRAS mutations in six of seven patients (86%); however, these mutations were present in only two of seven patients (29%) prior to treatment. Overall, the majority of circulating biomarkers (81% for CTCs and 91% for cfDNA/ctDNA) were detected after the start of neoadjuvant therapy but before surgery. This study suggests that a longitudinal study of circulating biomarkers throughout treatment provides more useful information than those single time-point tests for resectable PDAC patients.

Abstract
Background Patients with unresectable intrahepatic cholangiocarcinoma (iCCA) have poor survival. This systematic review describes the survival outcomes of hepatic arterial infusion pump (HAIP) chemotherapy with floxuridine for patients with unresectable iCCA. Patients and Methods A literature search was conducted using the electronic databases PubMed, Medline (Ovid), Embase, Web of Science, Google Scholar, and Cochrane to find studies that reported data on the survival of patients with unresectable iCCA treated with HAIP chemotherapy using floxuridine. The quality of the studies was assessed using the Newcastle–Ottawa quality assessment Scale (NOS). Overall survival (OS) was the primary outcome measure, and progression-free survival (PFS), response rates, resection rates, and toxicity were defined as secondary outcome measures. Results After removing duplicates, 661 publications were assessed, of which nine studies, representing a total of 478 patients, met the inclusion criteria. Three out of nine studies were phase II clinical trials, one study was a prospective dose-escalation study, and the remaining five studies were retrospective cohort studies. After accounting for overlapping cohorts, 154 unique patients were included for pooled analysis. The weighted median OS of patients with unresectable iCCA treated with HAIP chemotherapy with floxuridine was 29.0 months (range 25.0–39 months). The pooled 1-, 2-, 3-, and 5-year OS were 86.4, 55.5, 39.5, and 9.7%, respectively. Conclusion HAIP chemotherapy with floxuridine for patients with unresectable iCCA was associated with a 3-year OS of 39.5%, which is favorable compared with systemic chemotherapy for which no 3-year survivors were reported in the Advanced Biliary Cancer (ABC) trials.

Targeting STAT3 Signaling Facilitates Responsiveness of Pancreatic Cancer Cells to Chemoradiotherapy. Cancers (Basel) 2022; 14:cancers14051301. [PMID: 35267609 PMCID: PMC8908974 DOI: 10.3390/cancers14051301] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 02/24/2022] [Accepted: 02/27/2022] [Indexed: 02/05/2023] Open
Abstract
The debate is ongoing regarding the potential role of preoperative chemoradiotherapy (CRT) for patients with pancreatic ductal adenocarcinoma (PDAC), and whether it should be reserved for borderline resectable or unresectable tumors. However, treatment response is heterogeneous, implicating the need to unveil and overcome the underlying mechanisms of resistance. Activation of the transcription factor STAT3 was recently linked to CRT resistance in other gastrointestinal cancers such as rectal and esophageal cancers, but its role in PDAC needs to be clarified. Protein expression and phosphorylation of STAT3 was determined in PDAC cell lines and connected to transcriptional activity measured by dual-luciferase reporter gene assays. Inhibition of STAT3 signaling was achieved by RNAi or the small-molecule inhibitor napabucasin. We observed a positive correlation between STAT3 signaling activity and CRT resistance. Importantly, genetical and pharmacological perturbation of the IL-6/STAT3 pathway resulted in CRT sensitization specifically in those cell lines, in which STAT3 activity was augmented by IL-6. In conclusion, our data underscore the general importance of IL-6/STAT3 signaling for CRT resistance and suggest that pathway inhibition may represents a putative treatment strategy in order to increase the fraction of patients with PDAC who are candidates for surgical approaches.

Abstract
OBJECTIVES Indications of preoperative treatment for resectable (R-) or borderline resectable (BR-) pancreatic ductal adenocarcinoma (PDAC) are unclear, and the protocol remains to be standardized. METHODS Included 65 patients with R- and BR-PDAC with venous involvement (V-) received neoadjuvant chemoradiotherapy with S-1 and 50 Gy of radiation as the 5-week regimen. The outcomes of this group were compared with those of 52 patients who underwent S-1 and 30 Gy of radiation as the 2-week regimen, previously collected as our prospective phase II study. RESULTS Compared with the 2-week regimen, there were no significant differences in the rate of protocol completion, adverse events, mortality and morbidity, or R0 resection in the 5-week regimen. In subgroup analyses of R-PDAC, there were no significant differences in overall survival and recurrence-free survival between the groups. In contrast, the 5-week regimen had significantly better overall survival and recurrence-free survival than the 2-week regimen for BRV-PDAC. Similar results were observed after propensity score matching analysis. CONCLUSIONS The 5-week regimen of neoadjuvant chemoradiotherapy has good clinical efficacy and safety for R- and BRV-PDAC. The 5-week regimen could achieve better outcomes than the 2-week regimen for BRV-PDAC. In contrast, both regimens achieved similar outcomes for R-PDAC.

Abstract
OBJECTIVE To evaluate the association between staging concordance, treatment sequencing, and response to neoadjuvant therapy (NAT) on the survival of patients with pancreatic ductal adenocarcinoma (PDAC). SUMMARY OF BACKGROUND DATA NAT is increasingly utilized in the management of patients with PDAC, but it is unclear whether its benefit is contingent on tumor down-staging. METHODS This was a cohort study of stage I-III PDAC patients in the National Cancer Database (2006-2015) treated with upfront resection or NAT followed by surgery. We determined staging concordance using patients' clinical and pathological staging data. For NAT patients, we used Bayesian analysis to ascertain staging concordance accounting for down-staging. RESULTS Among 16,597 patients treated at 979 hospitals, 13,982 had an upfront resection and 2,615 NAT followed by surgery. Overall survival (OS) at 5-years ranged from 26.0% (95% CI 24.9%-27.1%) among cT1-2N0 patients to 18.6% (17.9%-19.2%) among cT1-3N+ ones. Patients with cT3-4 or cN+ tumors had improved OS after NAT compared to upfront surgery (all p< 0.001), while there was no difference among patients with cT1-2N0 (P = 0.16) disease. Relative to accurately staged cT1-2-3N+ or cT4 patients treated with upfront surgery, NAT was associated with a lower risk of death [HR 0.46 (0.37-0.57) for N+; HR 0.56 (0.40-0.77) for T4 disease], even among those without tumor down-staging [HR 0.81 (0.73-0.90) for N+; HR 0.48 (0.39-0.60) for T4]. CONCLUSIONS NAT is associated with improved survival for PDAC, particularly for patients with more advanced disease and regardless of down-staging. Consideration should be given to recommending NAT for all PDAC patients.

Current Limitations and Novel Perspectives in Pancreatic Cancer Treatment. Cancers (Basel) 2022; 14:cancers14040985.

Abstract
Simple Summary This review article presents a synopsis of the key clinical developments, their limitations, and future perspectives in the treatment of pancreatic cancer. In the first part, we summarize the available treatments for pancreatic cancer patients according to tumor stage, as well as the most relevant clinical trials over the past two decades. Despite this progress, there is still much to be improved in terms of patient survival. Therefore, in the second part, we consider various components of the tumor microenvironment in pancreatic cancer, looking for the key drivers of therapy resistance and tumor progression, which may lead to the discovery of new potential targets. We also discuss the most prominent molecules targeting the stroma and immune compartment that are being investigated in either preclinical or clinical trials. Finally, we also outline interesting venues for further research, such as possible combinations of therapies that may have the potential for clinical application. Abstract Pancreatic cancer is one of the deadliest cancers worldwide, largely due to its aggressive development. Consequently, treatment options are often palliative, as only one-fifth of patients present with potentially curable tumors. The only available treatment with curative intent is surgery followed by adjuvant chemotherapy. However, even for patients that are eligible for surgery, the 5-year OS remains below 10%. Hence, there is an urgent need to find new therapeutic regimens. In the first part of this review, we discuss the tumor staging method and its impact on the corresponding current standard-of-care treatments for PDAC. We also consider the key clinical trials over the last 20 years that have improved patient survival. In the second part, we provide an overview of the major components and cell types involved in PDAC, as well as their respective roles and interactions with each other. A deeper knowledge of the interactions taking place in the TME may lead to the discovery of potential new therapeutic targets. Finally, we discuss promising treatment strategies targeting specific components of the TME and potential combinations thereof. Overall, this review provides an overview of the current challenges and future perspectives in the treatment of pancreatic cancer.

Abstract
Worldwide, there is a shifting paradigm from immediate surgery with adjuvant treatment to a neoadjuvant approach for patients with resectable or borderline resectable pancreatic cancer (RPC or BRPC). Comparison of neoadjuvant and adjuvant studies is extremely difficult because of a great difference in patient selection. The evidence from randomized studies shows that overall survival by intention-to-treat improves after neoadjuvant gemcitabine-based chemoradiotherapy or chemotherapy (various regimens), as compared to immediate surgery followed by adjuvant chemotherapy. Radiotherapy appears to play an important role in mediating locoregional effects. Yet, since more effective chemotherapy regimens are currently available, in particular FOLFIRINOX and Gemcitabine/Nab-paclitaxel, these chemotherapy regimens should be investigated in future randomized trials combined with (stereotactic) radiotherapy to further improve outcomes of RPC and BRPC.

Abstract
Multimodal treatment including surgery and chemotherapy is considered the gold standard treatment of pancreatic cancer by most guidelines. Neoadjuvant therapy (NAT) has been seen as a possible treatment option for resectable, borderline resectable and locally advanced PaC. The aim of this paper is to offer a state-of-the-art review on neoadjuvant treatments in the setting of pancreatic ductal adenocarcinoma. A systematic literature search was performed using PubMed, Cochrane, Web of Science and Embase databases, in order to identify relevant studies published up to and including July 2021 that reported and analyzed the role of neoadjuvant therapy in the setting of pancreatic carcinoma. Most authors are concordant on the strong role of neoadjuvant therapy in the setting of borderline resectable pancreatic cancers. Recent randomized trials demonstrated improvement of R0 rate and survival after NAT in this setting. Patients with locally advanced cancers may become resectable after NAT, with better results than those obtained with palliative therapies. Even in the setting of resectable cancers, NAT is being evaluated by ongoing randomized trials. Chemotherapy regimens in the setting of NAT and response to NAT are discussed. NAT has an important role in the multimodal treatment of patients with borderline resectable pancreatic cancer. It has a role in patients with locally advanced tumors as it can allow surgical resection in a relevant proportion of patients. For resectable pancreatic cancers, the role of NAT is under evaluation by several randomized trials.

Abstract
BACKGROUND Nodal disease is prognostic in pancreatic ductal adenocarcinoma (PDAC); however, optimal number of examined lymph nodes (ELNs) required to accurately stage nodal disease in the current era of neoadjuvant therapy remains unknown. The aim of the study was to evaluate the optimal number of ELNs in patients with neoadjuvantly treated PDAC. METHODS A retrospective study was performed on patients with PDAC undergoing resection following neoadjuvant treatment between 2011 and 2018. Clinicopathological data were extracted and analyzed. RESULTS Of 546 patients included, 232 (42.5%) had lymph node metastases. The median recurrence free survival (RFS) was 10.6 months (95% confidence interval: 9.7-11.7) and nodal disease was independently associated with shorter RFS (9.1 vs 11.9 months; p < 0.001). A cutoff of 22 ELNs was identified that stratified patients by RFS. Patients with N1 and N2 disease had similar median RFS (9.1 vs 8.9 months; p = 0.410). On multivariable analysis, ELN of ≥ 22 was found to be significantly associated with longer RFS among patients with N0 disease (14.2 vs. 10.9 months, p = 0.046). However, ELN has no impact on RFS for patients with N1/N2 disease (9.5 vs. 8.4 months, p = 0.190). Adjuvant therapy was associated with RFS only in patients with residual nodal disease. CONCLUSIONS Lymph node metastases remain prognostic in PDAC patients after neoadjuvant treatment. Among N0 patients, a cutoff of 22 ELN was associated with improved RFS and resulted in optimal nodal staging.
