[PMID: 33157162 DOI: 10.1016/j.bbcan.2020.188461] [Citation(s) in RCA: 64] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Revised: 10/20/2020] [Accepted: 10/24/2020] [Indexed: 02/07/2023]
Abstract
Pancreatic cancer is a lethal disease with limited opportunity for resectable surgery as the first choice for cure due to its late diagnosis and early metastasis. The desmoplastic stroma and cellular genetic or epigenetic alterations of pancreatic cancer impose physical and biological barriers to effective therapies, including chemotherapy, radiotherapy, targeted therapy, and immunotherapy. Here, we review the current therapeutic options for pancreatic cancer, and underlying mechanisms and potential reversal of therapeutic resistance, a hallmark of this deadly disease.

Borderline Resectable and Locally Advanced Pancreatic Cancer: FDG PET/MRI and CT Tumor Metrics for Assessment of Pathologic Response to Neoadjuvant Therapy and Prediction of Survival. AJR Am J Roentgenol 2020; 217:730-740.

Abstract
BACKGROUND. Imaging biomarkers of response to neoadjuvant therapy (NAT) for pancreatic ductal adenocarcinoma (PDA) are needed to optimize treatment decisions and long-term outcomes. OBJECTIVE. The purpose of this study was to investigate metrics from PET/MRI and CT to assess pathologic response of PDA to NAT and to predict overall survival (OS). METHODS. This retrospective study included 44 patients with 18F-FDG-avid borderline resectable or locally advanced PDA on pretreatment PET/MRI who also underwent post-NAT PET/MRI before surgery between August 2016 and February 2019. Carbohydrate antigen 19-9 (CA 19-9) level, metabolic metrics from PET/MRI, and morphologic metrics from CT (n = 34) were compared between pathologic responders (College of American Pathologists scores 0 and 1) and nonresponders (scores 2 and 3). AUCs were measured for metrics significantly associated with pathologic response. Relation to OS was evaluated with Cox proportional hazards models. RESULTS. Among 44 patients (22 men, 22 women; mean age, 62 ± 11.6 years), 19 (43%) were responders, and 25 (57%) were nonresponders. Median OS was 24 months (range, 6-42 months). Before treatment, responders and nonresponders did not differ in CA 19-9 level, metabolic metrics, or CT metrics (p > .05). After treatment, responders and nonresponders differed in complete metabolic response (CMR) (responders, 89% [17/19]; nonresponders, 40% [10/25]; p = .04], mean change in SUVmax (ΔSUVmax; responders, -70% ± 13%; nonresponders, -37% ± 42%; p < .001), mean change in SUVmax corrected to serum glucose level (ΔSUVgluc) (responders, -74% ± 12%; nonresponders, -30% ± 58%; p < .001), RECIST response on CT (responders, 93% [13/14]; nonresponders, 50% [10/20]; p = .02)], and mean change in tumor volume on CT (ΔTvol) (responders, -85% ± 21%; nonresponders, 57% ± 400%; p < .001). The AUC of CMR for pathologic response was 0.75; ΔSUVmax, 0.83; ΔSUVgluc, 0.87; RECIST, 0.71; and ΔTvol 0.86. The AUCs of bivariable PET/MRI and CT models were 0.83 (CMR and ΔSUVmax), 0.87 (CMR and ΔSUVgluc), and 0.87 (RECIST and ΔTvol). OS was associated with CMR (p = .03), ΔSUVmax (p = .003), ΔSUVgluc (p = .003), and RECIST (p = .046). CONCLUSION. Unlike CA 19-9 level, changes in metabolic metrics from PET/MRI and morphologic metrics from CT after NAT were associated with pathologic response and OS in patients with PDA, warranting prospective validation. CLINICAL IMPACT. Imaging metrics associated with pathologic response and OS in PDA could help guide clinical management and outcomes for patients with PDA who undergo emergency therapeutic interventions.

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.

CA19-9 Change During Neoadjuvant Therapy May Guide the Need for Additional Adjuvant Therapy Following Resected Pancreatic Cancer. Ann Surg Oncol 2020; 27:3950-3960.

Abstract
BACKGROUND Neoadjuvant therapy (NAT) is increasingly utilized for pancreatic cancer, however the added benefit of adjuvant therapy (AT) in this setting is unknown. We hypothesized that the magnitude of CA19-9 response to NAT can guide the need for further AT in resected pancreatic cancer. METHODS CA19-9 secretors who received NAT for pancreatic cancer during 2008-2016 at a single institution were analyzed and CA19-9 response (difference between pre- and post-NAT values) was measured. Kaplan-Meier estimators and Cox proportional hazard ratio models were used to determine the optimal CA19-9 response at which AT ceases to confer any additional survival benefit after NAT. RESULTS A total of 241 patients (mean age 65.4 years, 50% female) with complete CA19-9 data who underwent NAT followed by resection were analyzed. In a cohort of patients (n = 78) in whom CA19-9 normalized with a decrease > 50% after NAT (optimal responders), AT was not associated with additional survival benefit (40.6 vs. 39.0 months, p = 0.815). Conversely, in the cohort of patients (n = 163) in whom NAT was not associated with normalization and a decrease of ≤ 50% in CA19-9 (suboptimal responders), receipt of AT was associated with a survival benefit (34.5 vs. 19.1 months, p < 0.001) following NAT. A Cox proportional hazards model confirmed CA19-9 normalization and decrease > 50% during NAT to predict no additional survival benefit from AT. CONCLUSIONS The magnitude of CA19-9 response to NAT may predict the need for further AT in resected pancreatic cancer. Prospective studies are needed to elucidate the optimal interplay of NAT and AT in pancreatic cancer.

Abstract
Pancreatectomy with arterial resection is a treatment option in selected patients with locally advanced pancreatic cancer. This study aimed to identify factors predicting cancer-specific survival in this patient population. A single-Institution prospective database was used. Pre-operative prognostic factors were identified and used to develop a prognostic score. Matching with pathologic parameters was used for internal validation. In a patient population with a median Ca 19.9 level of 19.8 U/mL(IQR: 7.1–77), cancer-specific survival was predicted by: metabolic deterioration of diabetes (OR = 0.22, p = 0.0012), platelet count (OR = 1.00; p = 0.0013), serum level of Ca 15.3 (OR = 1.01, p = 0.0018) and Ca 125 (OR = 1.02, p = 0.00000137), neutrophils-to-lymphocytes ratio (OR = 1.16; p = 0.00015), lymphocytes-to-monocytes ratio (OR = 0.88; p = 0.00233), platelets-to-lymphocytes ratio (OR = 0.99; p = 0.00118), and FOLFIRINOX neoadjuvant chemotherapy (OR = 0.57; p = 0.00144). A prognostic score was developed and three risk groups were identified. Harrell’s C-Index was 0.74. Median cancer-specific survival was 16.0 months (IQR: 12.3–28.2) for the high-risk group, 24.7 months (IQR: 17.6–33.4) for the intermediate-risk group, and 39.0 months (IQR: 22.7–NA) for the low-risk group (p = 0.0003). Matching the three risk groups against pathology parameters, N2 rate was 61.9, 42.1, and 23.8% (p = 0.04), median value of lymph-node ratio was 0.07 (IQR: 0.05–0.14), 0.04 (IQR:0.02–0.07), and 0.03 (IQR: 0.01–0.04) (p = 0.008), and mean value of logarithm odds of positive nodes was − 1.07 ± 0.5, − 1.3 ± 0.4, and − 1.4 ± 0.4 (p = 0.03), in the high-risk, intermediate-risk, and low-risk groups, respectively. An online calculator is available at www.survivalcalculator-lapdac-arterialresection.org. The prognostic factors identified in this study predict cancer-specific survival in patients with locally advanced pancreatic cancer and low Ca 19.9 levels undergoing pancreatectomy with arterial resection.

Abstract
BACKGROUND Biological factors are emphasized in borderline resectable pancreatic cancer (BRPC), and CA19-9 is an important factor for biological borderline resectability (b-BR). The aim of this study was to investigate the cut-off value of CA19-9 for biological borderline resectability and "biological downstaging" in chemoradiation therapy (CRT) for pancreatic cancer (PC). METHODS A total of 407 patients with anatomically resectable PC (a-R) and BRPC (a-BR) received preoperative gemcitabine-based CRT. The b-BR was determined, according to the CA19-9 value prior to preoperative CRT (pre-CA19-9), as the subgroup of a-R cases in which the survival was comparable with that in a-BR cases. "Biological downstaging" was determined based on prognostic analyses regarding the CA19-9 value after preoperative CRT (post-CA19-9) in association with the survival of R cases (a-R cases without the b-BR factor). RESULTS The 5-year survival of a-R patients with pre-CA19-9 > 120 U/mL was comparable with that of a-BR patients (44% vs 34%, p = 0.082). The survival of b-BR patients with post-CRT CA19-9 ≤ 37 U/mL (normalized) was comparably favorable with that of R patients (56% vs 65%, p = 0.369). The incidence of distant recurrence was higher in b-BR patients without post-CA19-9 normalization than in those with post-CA19-9 normalization (70% vs 50%, p = 0.003), while the incidence of local recurrence was comparable between these two groups (12% vs 13%, p = 0.986). CONCLUSIONS Biological BRPC was determined to be an anatomically resectable disease with pre-CA19-9 > 120 U/mL, and post-CA19-9 normalization indicated "biological downstaging" in b-BR in the preoperative CRT strategy.

Abstract
Pancreatic cancer is a highly fatal disease with a 5-year survival rate of approximately 10% in the USA, and it is becoming an increasingly common cause of cancer mortality. Risk factors for developing pancreatic cancer include family history, obesity, type 2 diabetes, and tobacco use. Patients typically present with advanced disease due to lack of or vague symptoms when the cancer is still localised. High quality computed tomography with intravenous contrast using a dual phase pancreatic protocol is typically the best method to detect a pancreatic tumour and to determine surgical resectability. Endoscopic ultrasound is an increasingly used complementary staging modality which also allows for diagnostic confirmation when combined with fine needle aspiration. Patients with pancreatic cancer are often divided into one of four categories based on extent of disease: resectable, borderline resectable, locally advanced, and metastatic; patient condition is also an important consideration. Surgical resection represents the only chance for cure, and advancements in adjuvant chemotherapy have improved long-term outcomes in these patients. Systemic chemotherapy combinations including FOLFIRINOX (5-fluorouracil, folinic acid [leucovorin], irinotecan, and oxaliplatin) and gemcitabine plus nab-paclitaxel remain the mainstay of treatment for patients with advanced disease. Data on the benefit of PARP inhibition as maintenance therapy in patients with germline BRCA1 or BRACA2 mutations might prove to be a harbinger of advancement in targeted therapy. Additional research efforts are focusing on modulating the pancreatic tumour microenvironment to enhance the efficacy of the immunotherapeutic strategies.

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.

Abstract
BACKGROUND The optimal cutoffs for carbohydrate antigen 19-9 (CA19-9) response after neoadjuvant therapy (NT) for pancreatic adenocarcinoma (PDAC) are not well characterized. This study aimed to analyze the relationship of serum CA19-9 to other markers of response and to identify thresholds correlating to outcomes. METHODS A retrospective review of resected PDAC patients from 2010 to 2017 at an academic tertiary referral center was conducted. RESULTS The analysis enrolled 250 subjects. Normalization and multiple cutoff points for CA19-9 response were assessed. Normalization was not associated with improved survival (35.17 vs. 29.43 months; p = 0.173). Although a response 45% or higher was associated with longer survival (35 vs. 20 months; p = 0.018), a response of 85% or higher was optimal (55.7 vs. 25.97 months; p < 0.0001). A response of 85% or higher remained a strong independent predictor of survival [hazard ratio (HR), 0.47; p = 0.007]. Subjects with a response of 85% or higher had received more NT cycles [3 (range 2-6) vs. 3 (range 2-4) cycles; p = 0.006] and fewer adjuvant cycles [4 (range 3-6) vs. 5 (range 3-6) cycles; p = 0.027]. Reduction in T-size correlated with a drop in CA19-9 and a size reduction of 25% or higher (56.97 vs. 28.17 months; p = 0.016) improved survival. A serum CA19-9 response of 85% or higher was a strong independent predictor of a reduction in T-size of 25% or higher (HR 2.40; p = 0.007). CONCLUSION A CA19-9 response of 85% or higher is the optimal threshold for predicting survival. It is predictive of T-size reduction. Future NT trials should incorporate CA19-9 response as an end point.

Abstract
Despite ongoing efforts, patients with locally advanced pancreatic cancer (LAPC) continue to have a dismal prognosis. Such tumors are unresectable, and optimal treatment with chemotherapy and/or radiation therapy is still not established. While chemotherapy is conventionally aimed at preventing metastatic spread of disease, radiation therapy acts locally, improving local control which can potentially improve overall survival and most importantly quality of life. Here, we aim to review the primary literature assessing the role of diverse radiation therapy strategies for patients with LAPC. Many radiation regimens can be considered, and no standard treatment has demonstrated a clear improvement in clinical outcomes. We advise that the modality of choice be dependent on the availability of equipment, the dose and fractionation of treatment, as well as the dose received by normal tissue. Moreover, a candid discussion with the patient concerning treatment goals is equally as essential. Three notable strategies for LAPC are intensity-modulated radiation therapy, volumetric modulated arc therapy, and proton. These radiation modalities tend to have improved dose distribution to the target volumes, while minimizing the radiation dose to surrounding normal tissues. Stereotactic body radiation therapy can also be considered in LAPC patients in cases where the tumor does not invade the duodenum or other neighboring structures. Because of the high doses delivered by stereotactic body radiation therapy, proper respiratory and tumor motion management should be implemented to reduce collateral radiation dosing. Despite improved clinical outcomes with modern radiation modalities, evolving techniques, and more accurate planning, future studies remain essential to elucidate the optimal role for radiation therapy among patients with LAPC.

Neoadjuvant-modified FOLFIRINOX vs nab-paclitaxel plus gemcitabine for borderline resectable or locally advanced pancreatic cancer patients who achieved surgical resection. Cancer Med 2020; 9:4711-4723. [PMID: 32415696 PMCID: PMC7333854 DOI: 10.1002/cam4.3075] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2019] [Revised: 04/02/2020] [Accepted: 04/05/2020] [Indexed: 12/11/2022] Open
Abstract
We conducted an institutional study to compare the clinical and pathological efficacy between the neoadjuvant therapy (NAT)‐modified FOLFIRINOX (mFOLF) vs nanoparticle albumin–bound paclitaxel plus gemcitabine (nab‐P/G) for borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC) patients who completed resection. The study retrospectively enrolled patients with pathologically confirmed BRPC or LAPC from 2010 to 2018 at our institution. The survival rates were determined by the Kaplan‐Meier method and log‐rank test was used to test differences. Cox's proportional hazard model was used to assess survival with respect to covariates. Seventy‐two patients who completed at least two cycles of neoadjuvant chemotherapy and surgical resection were included, with 52 (72.2%) patients receiving mFOLF and 20 (27.8%) receiving nab‐P/G. Patients treated with mFOLF had statistically higher rates of RECIST 1.1 partial or complete response (16/52 vs 1/20, P = .028). Additionally, mFOLF patients had greater pathological tumor size reduction, fewer positive lymph nodes, and higher treatment response grade compared to the nab‐P/G patients (all P < .05). The median overall survival was 33.3 months vs 27.1 months (P = .105), and distant metastasis‒free survival (DMFS) was 21.3 months vs 14.6 months (P = .042) in the mFOLF vs nab‐P/G groups, respectively. On multivariate analysis, mFOLF (hazard ratio, 0.428; 95% confidence interval [CI], 0.186‐0.987) and abnormal postoperative CA 19‐9 (hazard ratio, 2.47; 95% CI, 1.06‐5.76) were associated with DMFS. Among patients with BRPC and LAPC who complete surgical resection, neoadjuvant mFOLF was associated with improved pathological and clinical outcomes compared with nab‐P/G.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is becoming increasingly more common. Treatment for PDAC is dependent not only on stage at diagnosis, but complex anatomical relationships. Recently, the therapeutic approach to this disease has shifted from upfront surgery for technically resectable lesions to a neoadjuvant therapy first approach. Selecting an appropriate regimen and determining treatment response is crucial for optimal oncologic outcome, especially since radiographic imaging has proven unreliable in this setting. Tumor biomarkers have the potential to play a key role in treatment planning, treatment monitoring, and surveillance as an adjunct laboratory test. In this review, we will discuss common chemotherapeutic options, mechanisms of resistance, and potential biomarkers for PDAC. The aim of this paper is to present currently available biomarkers for PDAC and to discuss how these markers may be affected by neoadjuvant chemotherapy treatment. Understanding current chemotherapy regiments and mechanism of resistance can help us understand which markers may be most affected and why; therefore, determining to what ability we can use them as a marker for treatment progression, prognosis, or potential relapse.

Abstract
BACKGROUND As neoadjuvant therapy of borderline resectable pancreatic cancer (BRPC) is becoming more widely used, better indicators of progression are needed to help guide therapeutic decisions. MATERIALS AND METHODS A retrospective review was performed on all patients with BRPC who received 24 weeks of neoadjuvant chemotherapy. Patients with chemotoxicity or medical comorbidities limiting treatment completion and nonexpressors of carbohydrate antigen 19-9 (CA19-9) were excluded. Serum CA19-9 response was analyzed as a predictor of disease progression, recurrence, and survival. RESULTS One hundred four patients were included; 39 (37%) progressed on treatment (18 local and 21 distant) and 65 (63%) were resected (68% R0). Multivariate logistic regression analysis determined that the percent decrease in CA19-9 from baseline to minimum value (odds ratio [OR] 0.947, p ≤ .0001) and the percent increase from minimum value to final restaging CA19-9 (OR 1.030, p ≤ .0001) were predictive of progression. A receiver operating characteristics curve analysis determined cutoff values predictive of progression, which were used to create four prognostic groups. CA19-9 responses were categorized as follows: (1) always normal (n = 6); (2) poor response (n = 31); (3) unsustained response (n = 19); and (4) sustained response (n = 48). Median overall survival for Groups 1-4 was 58, 16, 20, and 38 months, respectively (p ≤ .0001). CONCLUSION Patients with initially elevated CA19-9 levels who do not have a decline to a sustained low level are at risk for progression, recurrence, and poor survival. Alternative treatment strategies prior to an attempt at curative resection should be considered in this cohort. IMPLICATIONS FOR PRACTICE This study identified percent changes in carbohydrate antigen 19-9 blood levels while on chemotherapy that predict tumor growth in patients with advanced pancreas cancer. These changes could be used to better select patients who would benefit from surgical removal of their tumors and improve survival.

Value of Pretreatment 18F-fluorodeoxyglucose Positron Emission Tomography in Patients With Localized Pancreatic Cancer Treated With Neoadjuvant Therapy. Front Oncol 2020; 10:500. [PMID: 32363161 PMCID: PMC7180175 DOI: 10.3389/fonc.2020.00500] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Accepted: 03/19/2020] [Indexed: 12/16/2022] Open
Abstract
Background:18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) imaging is not routine in patients with localized pancreatic cancer (PC). We evaluated the prognostic value of PET/CT in patients who received neoadjuvant therapy. Methods: Patients with localized PC underwent pretreatment PET/CT with or without posttreatment (preop) PET/CT. Maximum standardized uptake values (SUV) were classified as high or low based on a cut point of 7.5 at diagnosis (SUVdx) and 3.5 after neoadjuvant therapy (preoperative; SUVpreop). Preop carbohydrate antigen 19-9 (CA19-9) was classified as normal ( ≤ 35 U/mL) or elevated. Results: Pretreatment PET/CT imaging was performed on 201 consecutive patients; SUVdx was high in 98 (49%) and low in 103 (51%). Preop PET/CT was available in 104 (52%) of the 201 patients; SUVpreop was high in 60 (58%) and low in 44 (42%). Following neoadjuvant therapy, preop CA19-9 was normal in 90 (45%) patients and elevated in 111 (55%). Median overall survival (OS) of all patients was 27 months; 33 months for the 103 patients with a low SUVdx and 22 months for the 98 patients with a high SUVdx (p = 0.03). Median OS for patients with low SUVdx/normal preop CA19-9, high SUVdx/normal preop CA19-9, low SUVdx/elevated preop CA19-9, and high SUVdx/elevated preop CA19-9 were 66, 34, 23, and 17 months, respectively (p < 0.0001). OS was 44 months for the 148 (74%) patients who completed all intended neoadjuvant therapy and surgery and 13 months for the 53 (26%) who did not undergo surgery (p < 0.001). Conclusion: Pretreatment PET/CT avidity and preop CA19-9 are clinically significant prognostic markers in patients with PC.

Abstract
Evaluation of response to preoperative therapy for patients with pancreatic adenocarcinoma has been historically difficult. Therefore, preoperative regimens have generally been selected on the basis of baseline data such as radiographic stage and serum CA 19-9 level and then typically administered for a pre-specified duration as long as 6 months or more. The decision to proceed with resection following preoperative therapy likewise has rested upon the absence of disease progression rather than evidence for tumor response. This article reviews the basis for the evaluation of therapeutic response after preoperative therapy for pancreatic cancer in the existing scientific literature, and providing updates and new perspectives.

Abstract
BACKGROUND Defining optimal treatment duration in patients with resectable pancreatic ductal adenocarcinoma (PDAC) receiving primary chemotherapy is an unmet need. The role of time to CA19-9 nadir and of nadir magnitude was explored in this study. PATIENTS AND METHODS The databases of our institution's prospective trials were queried to speculate on the time to maximum chemotherapy response. Patients with pathologically proven, metastatic (N = 356) or non-metastatic non-resected (N = 163) PDAC and elevated baseline (> 34 UI/mL) CA19-9 were analyzed. Survival curves were estimated using the Kaplan-Meier method and compared by means of the log-rank test for analyses including at least 45 patients. Multivariable Cox proportional hazards model was used to estimate clinical features for their association with OS. All probability values were from two-sided tests. RESULTS Time to CA19-9 nadir was ≥ 4 months in 184 of 346 (53%) metastatic and 121 of 163 (74%) non-metastatic patients (p = 0.002). The likelihood of a later nadir was higher with taxane-based chemotherapy as compared to taxane-free combinations (73% versus 56%; p = 0.02). Both metastatic and non-metastatic patients had significantly longer survival when nadir occurred later. Patients with a larger CA19-9 nadir magnitude had significantly longer survival. Metastatic patients with CA19-9 reduced by < 50%, 50-89%, or > 89% and had a median survival of 7.4, 9.8, and 14.7 months, respectively (p ≤ 0.001 for all comparisons). The corresponding figures for non-metastatic patients were 10.6; 17.0; and 18.7 months, respectively (p ≤ 0.02 for < 50% versus 50-89% or > 89%; p = 0.14 for 50-89% versus > 89%). Multivariable analyses showed that time to CA19-9 nadir but not CA19-9 nadir magnitude was independently predictive of survival. CONCLUSION The present study suggests that a 4-6 months program might be a more suitable candidate for prospective assessment in comparison to shorter pre-defined period in patients who are candidates to surgery after primary chemotherapy.

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.

Prognostic Value of the Systemic Immune-Inflammation Index (SII) After Neoadjuvant Therapy for Patients with Resected Pancreatic Cancer. Ann Surg Oncol 2020; 27:898-906.

Abstract
BACKGROUND The systemic immune-inflammation index (SII), calculated using absolute platelet, neutrophil, and lymphocyte counts, has recently emerged as a predictor of survival for patients with pancreatic ductal adenocarcinoma (PDAC) when assessed at diagnosis. Neoadjuvant therapy (NAT) is increasingly used in the treatment of PDAC. However, biomarkers of response are lacking. This study aimed to determine the prognostic significance of SII before and after NAT and its association with the pancreatic tumor biomarker carbohydrate-antigen 19-9 (CA 19-9). METHODS This study retrospectively analyzed all PDAC patients treated with NAT before pancreatic resection at a single institution between 2007 and 2017. Pre- and post-NAT lab values were collected to calculate SII. Absolute pre-NAT, post-NAT, and change in SII after NAT were evaluated for their association with clinical outcomes. RESULTS The study analyzed 419 patients and found no significant correlation between pre-NAT SII and clinical outcomes. Elevated post-NAT SII was an independent, negative predictor of overall survival (OS) when assessed as a continuous variable (hazard ratio [HR], 1.0001; 95% confidence interval [CI] 1.00003-1.00014; p = 0.006). Patients with a post-NAT SII greater than 900 had a shorter median OS (31.9 vs 26.1 months; p = 0.050), and a post-NAT SII greater than 900 also was an independent negative predictor of OS (HR, 1.369; 95% CI 1.019-1.838; p = 0.037). An 80% reduction in SII independently predicted a CA 19-9 response after NAT (HR, 4.22; 95% CI 1.209-14.750; p = 0.024). CONCLUSION Post-treatment SII may be a useful prognostic marker in PDAC patients receiving NAT.

Induction chemotherapy in pancreatic cancer: CA 19-9 may predict resectability and survival. HPB (Oxford) 2020; 22:224-232.

Abstract
BACKGROUND Preoperative/Neoadjuvant treatment (NT) is increasingly used in unresectable pancreatic cancer (PDAC). However, ∼40% of patients cannot be resected after NT and reliable preoperative response evaluation is currently lacking. We investigated CA 19-9 levels and their dynamics during NT for prediction of resectability and survival. METHODS We screened our institution's database for patients who underwent exploration or resection after NT with gemcitabine-based therapy (GEM) or FOLFIRINOX (FOL). Pre- and post-NT CA 19-9, resection rate and survival were analyzed. RESULTS Of 318 patients 165 (51.9%) were resected and 153 (48.1%) received exploration. In the FOL group (n = 103; 32.4%), a post-NT CA 19-9 cutoff at 91.8 U/ml had a sensitivity of 75.0% and a specificity of 76.9% for completing resection with an AUC of 0.783 in the ROC analysis (95% CI: 0.692-0.874; p < 0.001. PPV: 84.2%, NPV: 65.2%). Resected patients above the cutoff did not benefit from resection. Post-NT CA 19-9 <91.8 U/ml (OR 11.63, p < 0.001) and CA 19-9 ratio of <0.4 (OR 5.77, p = 0.001) were independent predictors for resectability in FOL patients. DISCUSSION CA 19-9 levels after neoadjuvant treatment with FOLFIRINOX predict resectability and survival of PDAC more accurately than dynamic values and should be incorporated into response evaluation and surgical decision-making.

Abstract
BACKGROUND This study aimed to explore the impact of serum tumor markers on survival for patients with pancreatic cancer (PC) who received initial systemic therapy (IST) followed by surgery. METHODS Between April 2010 and July 2018, 285 consecutive patients who underwent curative intent surgery for PC were enrolled in the study. The relation between carbohydrate antigen 19-9 and duke pancreatic monoclonal antigen type 2 (DUPAN-2) after IST was analyzed as well as PC prognosis. RESULTS The study identified 95 patients who underwent systemic chemotherapy with or without radiotherapy as IST from the our prospectively maintained database at the Department of Gastroenterological Surgery (Surgery II), Nagoya University Graduate School of Medicine, Nagoya, Japan. Survival analysis of the 95 patients showed significant differences in recurrence-free survival (RFS) and overall survival (OS) between the DUPAN-2-normalized (D-normalized) and DUPAN-2-unnormalized (D-unnormalized) groups (median RFS, 24.1 vs. 14.2 months, p = 0.003; median OS, not reached vs. 29.6 months, p = 0.003). In addition, a tendency of differences in survival was observed between the D-normalized and D-unnormalized groups with borderline resectable PC (RFS, 20.1 vs. 14.2 months, p = 0.052; OS, not reached vs. 29.6 months, p = 0.081), and significant differences in survival were observed between the D-normalized and D-unnormalized groups with unresectable PC (RFS, 25.1 vs. 12.1 months, p < 0.001; OS, not reached vs. 11.4 months, p < 0.001). Furthermore, multivariate analysis demonstrated that normalized DUPAN-2 independently predicted survival of resected PC [RFS: hazard ratio (HR) 2.180; 95% confidence interval (CI) 1.16-4.08, p = 0.015; OS: HR 2.806; 95% CI 1.19-6.62, p = 0.018]. CONCLUSIONS During IST, DUPAN-2 normalization may potentially predict prolonged survival for PC patients and optimal timing for conversion surgery in IST.

Abstract
PURPOSE Effective preoperative regimens and biomarkers for pancreatic ductal adenocarcinoma (PDAC) are lacking. We prospectively evaluated fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX)-based treatment and imaging-based biomarkers for borderline resectable PDAC. METHODS Eligible patients had treatment-naïve, histology-confirmed PDAC and one or more high-risk features: mesenteric vessel involvement, CA 19-9 level of 500 mg/dL or greater, and indeterminate metastatic lesions. Patients received modified FOLFIRINOX and chemoradiation before anticipated pancreatectomy. Tumors were classified on baseline computed tomography as high delta (well-defined interface with parenchyma) or low delta (ill-defined interface). We designated computed tomography interface response after therapy as type I (remained or became well defined) or type II (became ill defined). The study had 80% power to differentiate a 60% from 40% resection rate (α = .10). Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method, and subgroups were compared using log-rank tests. RESULTS Thirty-three patients initiated therapy; 45% underwent pancreatectomy. The median OS was 24 months (95% CI, 16.2 to 29.6 months). For patients who did and did not undergo pancreatectomy, the median OS was 42 months (95% CI, 17.7 months to not estimable) and 14 months (95% CI, 9.0 to 24.8 months), respectively. Patients with high-delta tumors had lower 3-year PFS (4% v 40%) and 3-year OS rates (20% v 60%) than those with low-delta tumors (both P < .05). Patients with type II interface responses had lower 3-year PFS (0% v 29%) and 3-year OS rates (16% v 47%) than those with type I responses (both P < .001). CONCLUSION Preoperative FOLFIRINOX followed by chemoradiation for high-risk borderline resectable PDAC was associated with a resection rate of 45% and median OS of approximately 2 years. Our imaging-based biomarker validation indicates that personalized treatment may be achieved using these biomarkers at baseline and post-treatment.

Abstract
In 2018, pancreatic ductal adenocarcinoma (PDAC) was the 3rd highest cause cancer related death in the United States. Worldwide estimates in 2018 indicate 458,918 cases diagnosed with 432,242 deaths. Standard therapy for decades for localized PDAC has been to pursue surgical resection for localized disease. For the individuals who are diagnosed with localized PDAC and undergo surgical resection, historical survival has been reported to be around 24 months. While recent advancements in the use of multiagent systemic therapy has allowed for greater survival benefit, adjuvant therapy does have limitations. Recently, neo-adjuvant therapy for PDAC has become more accepted in practice. Areas covered: In this review, we will discuss the current guidelines for treatment of localized PDAC, the pros and cons of neo-adjuvant versus adjuvant therapy for PDAC, the utilization of available biomarkers for the management of PDAC, and future possibilities for clinical trials. Expert commentary: Neo-adjuvant therapy for localized PDAC has tremendous promise in leading to greater survival by treating for micro-metastatic disease along with selecting for patients for better outcomes. Further work based upon molecular insights will lead to better biomarkers for treatment assessment along with improvements in treatment.

Abstract
BACKGROUND Achieving margin negative resection is a significant determinant of outcome in pancreatic adenocarcinoma (PDA). However, because of the fibrotic nature of PDA, it can be difficult to discriminate fibrosis from active disease intra-operatively. We sought to determine if post-hoc video review of robotic pancreatico-duodenectomy (RPD) could predict the portal/superior mesenteric vein (PV/SMV) margin status on final pathology. METHODS Experienced pancreatic surgeons, blinded to patient and operative variables, reviewed the PV/SMV margin for available RPD videos of consecutive PDA patients from 9/2012 through 6/2017. RESULTS 107 RPD videos were reviewed. Of 76 patients (71%) predicted to have a negative vein margin on video review, 20 patients (26%) had a pathologic positive margin. 25 of 31 patients (81%) predicted to have positive margin on video review were positive on pathology. The specificity of video prediction was 90.3% with a sensitivity of 55.6% and an accuracy of 75.7%. CONCLUSION Post-hoc video review prediction is unable to reliably predict a positive (R1) margin at the portal vein/SMV, suggesting that intra-operative clinical assessment may be suboptimal in determining the need for more extensive resections.

Abstract
The efficacy of preoperative neoadjuvant chemoradiotherapy (NAC) in cases of pancreatic cancer with extremely poor prognoses has been reported. In this study, we aimed to identify novel biomarkers that reflect prognoses following chemoradiotherapy using tertiary lymphoid organs (TLO) expressed in the tumor microenvironment. Resected tumor specimens were obtained from 140 pancreatic cancer patients. We retrospectively investigated the clinical relevance of TLO by categorizing patients into those who underwent upfront surgery (surgery first [SF]) and those who received NAC. The immunological elements within TLO were analyzed by immunohistochemistry (IHC). In the IHC analysis, the proportions of CD8+ T lymphocytes, PNAd+ high endothelial venules, CD163+ macrophages and Ki‐67+ cells within the TLO were higher in the NAC group than in the SF group. In contrast, the proportion of programmed cell death‐1+ immunosuppressive lymphocytes within TLO was lower in the NAC group than in the SF group. The NAC group demonstrated favorable prognoses compared with the SF group. In the multivariate analysis, the TLO/tumor ratio was determined as an independent predictive prognostic factor. In conclusion, the administration of preoperative chemoradiotherapy may influence the immunological elements in the tumor microenvironment and result in favorable prognoses in pancreatic ductal adenocarcinoma patients.

Decreased serum carbohydrate antigen 19-9 levels after neoadjuvant therapy predict a better prognosis for patients with pancreatic adenocarcinoma: a multicenter case-control study of 240 patients. BMC Cancer 2019; 19:252. [PMID: 30898101 PMCID: PMC6427838 DOI: 10.1186/s12885-019-5460-4] [Citation(s) in RCA: 56] [Impact Index Per Article: 11.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2018] [Accepted: 03/12/2019] [Indexed: 12/15/2022] Open
Abstract
Background Carbohydrate antigen (CA) 19–9 levels after resection are considered to predict prognosis; however, the significance of decreased CA19–9 levels after neoadjuvant therapy has not been clarified. This study aimed to define the prognostic significance of decreased CA19–9 levels after neoadjuvant therapy in patients with pancreatic adenocarcinoma. Methods Between 2001 and 2012, 240 consecutive patients received neoadjuvant therapy and subsequent resection at seven high-volume institutions in Japan. These patients were divided into three groups: Normal group (no elevation [≤37 U/ml] before and after neoadjuvant therapy), Responder group (elevated levels [> 37 U/ml] before neoadjuvant therapy but decreased levels [≤37 U/ml] afterwards), and Non-responder group (elevated levels [> 37 U/ml] after neoadjuvant therapy). Analyses of overall survival and recurrence patterns were performed. Uni- and multivariate analyses were performed to clarify the clinicopathological factors influencing overall survival. The initial metastasis sites were also evaluated in these groups. Results The Responder group received a better prognosis than the Non-responder group (3-year overall survival: 50.6 and 41.6%, respectively, P = 0.026), but the prognosis was comparable to the Normal group (3-year overall survival: 54.2%, P = 0.934). According to the analysis of the receiver operating characteristic curve, the CA19–9 cut-off level defined as no elevation after neoadjuvant therapy was ≤103 U/ml. The multivariate analysis revealed that a CA19–9 level ≤ 103 U/ml, (P = 0.010, hazard ratio: 1.711; 95% confidence interval: 1.133–2.639), tumor size ≤27 mm (P = 0.040, 1.517; (1.018–2.278)), a lack of lymph node metastasis (P = 0.002, 1.905; (1.276–2.875)), and R0 status (P = 0.045, 1.659; 1.012–2.627) were significant predictors of overall survival. Moreover, the Responder group showed a lower risk of hepatic recurrence (18%) compared to the Non-responder group (31%), though no significant difference in loco-regional, peritoneal or other distant recurrence were observed between groups (P = 0.058, P = 0.700 and P = 0.350, respectively). Conclusions Decreased CA19–9 levels after neoadjuvant therapy predicts a better prognosis, with low incidence of hepatic recurrence after surgery.

Abstract
OBJECTIVES To evaluate clinical/histological response and prognosis between preoperative gemcitabine-based chemoradiation therapy (G-CRT) and gemcitabine plus S1-based CRT (GS-CRT) for localized pancreatic ductal adenocarcinoma patients according to the 3 resectability groups. METHODS Among 199 patients who had 90% or more relative dose intensity of chemotherapy and completion of radiotherapy preoperatively (G-CRT: 98 and GS-CRT: 101), the subjects were 113 patients (G-CRT: 60 and GS-CRT: 53) who underwent curative-intent resection, and we compared clinical and histological effects between the 2 regimens. RESULTS There is a significant improvement in clinical and histological responses as assessed by reduction rate in tumor size, post-CRT serum level of carbohydrate antigen 19-9, and the ratio of histological high responder according to the Evans grading system in GS-CRT, as compared with G-CRT, which in turn significantly increased R0 resection rate (P = 0.013). These effects of GS-CRT resulted in significant improvement of disease-specific survival (median survival time, 36.0 vs 27.2 months; P = 0.042), especially in patients with unresectable locally advanced disease (36.0 vs 18.1 months, P = 0.014). CONCLUSIONS For localized pancreatic ductal adenocarcinoma patients, GS-CRT, as compared with G-CRT, provides significant improvement in clinical and histological response as well as long-time survival, especially in patients with unresectable locally advanced disease.

Abstract
Pancreatic cancer is a lethal disease with a very poor prognosis. In contrast to treatments for many other tumor types, cytotoxic agents are still the first-line drugs for pancreatic cancer in both the palliative and adjuvant settings. Some progress has been made in recent years, but most large phase 3 studies have not shown significant improvements in survival. Because the available drugs and regimens are limited in both type and effect, the selection of chemotherapy based on clinicopathologic characteristics may be consequential for pancreatic cancer. In the present report, we focused on 7 landmark clinical trials for pancreatic cancer. We observed that FOLFIRINOX (oxaliplatin, irinotecan, fluorouracil, and leucovorin) and NG (nab-paclitaxel and gemcitabine), 2 first-line regimens, exerted opposite effects on metastatic pancreatic cancer patients with different baseline carbohydrate antigen 19-9 (CA19-9) levels. This suggested that not only the performance status but possibly also CA19-9 levels should be considered when making a therapeutic choice for patients with advanced pancreatic cancer. Moreover, we found that patients with a diagnosis of pancreatic cancer who have undergone a surgical resection with a negative margin (R0) may benefit more from fluorouracil and/or oral prodrugs of fluorouracil-based adjuvant therapy than from gemcitabine. Conversely, gemcitabine or gemcitabine-based regimens may be more effective for patients with a positive resection margin (R1). Based on these findings, we propose flowcharts for selecting chemotherapy for both advanced and resected pancreatic cancer. Furthermore, we present possible mechanisms and interpretations underlying the selection of chemotherapy for pancreatic cancer and propose the tumor burden as a key variable in this process. Regardless of the possible bias and exact treatment selection process, this study offers an opportunity to improve patient outcomes by using agents currently used in the therapy of pancreatic cancer. Although these conclusions are based on indirect evidence, we provide insights and possibilities to drive the selection of chemotherapy for pancreatic cancer.

Abstract
Backgrounds/Aims We performed a retrospective, single-center cohort study to evaluate the impact of various treatment modalities and recent changes in treatment modalities, including the increased application of chemotherapy, on survival in patients with pancreatic cancer. Methods All patients with pancreatic cancer who were diagnosed and treated at Seoul National University Hospital between January 2007 and December 2014 were registered in a prospective clinical database and included in this retrospective study. All patients' radiologic imaging diagnoses were re-reviewed according to the National Cancer Center Network guidelines. The patients were divided into four groups according to their clinical stage, and each clinical stage group was further divided into four groups according to treatment modality. Results Overall, 475 (28.9%) patients had resectable pancreatic cancer, 129 (7.8%) patients borderline resectable pancreatic cancer, 384 (23.3%) patients locally advanced pancreatic cancer, and 658 (40.0%) patients metastatic pancreatic cancer. Among the patients with borderline resectable pancreatic cancer, the median survival was significantly longer in the neoadjuvant therapy (NAT)+surgery groups (24 months) than the surgery without NAT (16 months) group (p=0.049). A multivariate survival analysis revealed that compared with the surgery group, the 5-year mortality risk was decreased by 35% in the NAT+surgery group (24 vs. 20 months, p=0.045). Conclusions This retrospective cohort study showed that the rates of resectable and surgically treatable pancreatic cancer were 29.1% and 32.2%, which are higher than those reported previously, and aggressive NAT for select advanced-stage patients could lead to better survival outcomes.

CA19-9 on Postoperative Surveillance in Pancreatic Ductal Adenocarcinoma: Predicting Recurrence and Changing Prognosis over Time. Ann Surg Oncol 2018; 25:3483-3491.

Abstract
BACKGROUND Serum carbohydrate antigen 19-9 (CA19-9) correlates with response to therapy and overall survival (OS) for patients with pancreatic ductal adenocarcinoma (PDAC). This study aimed to define the chronologic relationship between CA19-9 elevation and radiographic recurrence to develop a model that can predict the risk of recurrence (RFS) and prognosis during interval surveillance for patients with resected PDAC. METHODS A retrospective review examined patients undergoing surgery for pancreatic adenocarcinoma from January 2010 to May 2016. Their CA19-9 levels were classified at diagnosis, after surgery, and at 6-month surveillance intervals. Recurrence was defined by radiographic evidence. The CA19-9 levels were correlated with RFS and OS at every time point using multivariate analysis. RESULTS The study examined 525 patients. Five patterns of CA19-9 were identified: normal ("nonsecretors," 18.5%), always elevated, and high at diagnosis but normal after resection involving three patterns with varied behavior during surveillance. These five patterns had implications for RFS and OS. When elevation of CA19-9, as assessed at 6-month intervals, was analyzed relative to detection of radiographic disease, CA19-9 had poor positive predictive value (average, 35%) but high negative predictive value (average, 92%) for radiographic recurrence. Conditional RFS showed that CA19-9 elevation did not equal radiographic recurrence but predicted subsequent RFS. Additionally, conditional OS showed that CA19-9 elevation alone was predictive at each time point. CONCLUSION This study showed that CA19-9 patterns beyond the post-resection period predict RFS and OS. High CA19-9 frequently is discordant with recurrence on imaging and may precede it by more than 6 months. At each surveillance interval, CA19-9 is predictive of prognosis, which may help in counseling patients and could be used to direct protocols of salvage chemotherapy.

Abstract
BACKGROUND: Presurgical carbohydrate antigen 19-9 (CA19-9) level predicts overall survival (OS) in resected pancreatic adenocarcinoma (PaC). The aim of this pooled analysis was to evaluate if presurgical CA19-9 level can also predict local control (LC) and distant metastasis-free survival (DMFS). METHODS: Seven hundred patients with PaC from eight institutions who underwent surgical resection ± adjuvant treatment between 2000 and 2014 were analyzed. Patients were divided based on four presurgical CA19-9 level cutoffs (5, 37, 100, 353 U/ml). Weibull regression model to identify independent predictors of OS on 404 patients with complete information was fitted. RESULTS: Median follow-up was 17 months (range: 2-225 months). Univariate analysis showed a better prognosis in pT1-2, pN0, diameter <30 mm, or grade 1 tumors and in patients undergoing R0 resection, distal pancreatectomy, or adjuvant chemotherapy and with lower CA19-9 levels. Five-year OS, LC, and DMFS were as follows: CA19-9 <5.0: 5.7%, 47.2%, 17.0%; CA19-9 5.1-37.0: 37.9%, 63.3%, 46.0%; CA19-9 37.1-100.0: 27.1%, 59.4%, 39.0%; CA19-9 100.1-353.0: 17.4%, 43.4%, 26.7%; CA19-9 >353.1: 10.9%, 50.2%, and 23.4%, respectively. At multivariate analysis, CA19-9 >100 and <353 level (P=.002), CA19-9 ≥353.1 (P<.001) level, G3 tumor (P=.002), and tumor diameter >30 mm (P<.001) correlated with worse OS. Patients treated with postoperative chemoradiation doses >50.0 Gy showed improved OS (P<.001). CONCLUSION: Presurgical CA19-9 predicts both OS and pattern of failure. Therefore, CA19-9 should be included in predictive models in order to customize treatments based on prognostic factors. Moreover, future studies should stratify patients according to presurgical CA19-9 level.

Abstract
The complexity of endocrine tumor diagnosis stems from its variable symptoms and presentation that may mimic many other disease states, or display asymptomatic properties for a prolonged amount of time. Early and accurate disease identification is needed for better patient prognosis. The key to this may be in using validated biomarkers with enhanced sensitivity and specificity. Several biomarkers are consistently used across various endocrine tumor types, possibly indicating a deeper pathophysiological mechanism behind endocrine cancer genesis and development. For example, carbohydrate antigen (CA) is measured in both pancreatic adenocarcinoma as well as ovarian cancer for diagnosis, surveillance, and risk stratification. The discovery of measuring miRNAs that are highly expressed in malignant tumors is also a novel strategy across multiple endocrine tumor types, and is propelling the future advancement of biomarker development. This review introduces currently utilized biomarkers in some of the commonly known endocrine tumors, including thyroid, adrenal, pituitary, pancreatic, and gonadal carcinoma, as well as future research directions.

Abstract
Recently, several reports demonstrated the efficacy of neoadjuvant chemotherapy (NAC) or chemoradiotherapy (NACRT) for patients with borderline resectable (BRPC) and locally advanced unresectable pancreatic carcinoma (LAPC). The aim of this study was to evaluate the treatment response after NACRT, especially for nerve plexuses, and the optimal resection area for superior mesenteric artery nerve plexuses in BRPC and LAPC patients after NACRT.A total of 17 patients with BRPC and LAPC received preoperative gemcitabine-based NACRT. The numbers of BRPC and LAPC patients were 13 and 4, respectively. We evaluated nerve plexus invasion by CT before and after NACRT, decided on the resection area of plexus invasion in SMA before NACRT, and compared the preoperative evaluation and clinicopathological findings.In the plexus of the supra-mesenteric artery (pl-SMA), arterial nerve plexus invasion, in cases <90°, all patients showed the absence of residual cancer in the resected specimen after NACRT. In cases between 90° and 180°, 1 of 2 patients (50%) showed nerve plexus invasion. In cases over 180°, all patients showed nerve plexus invasion. We could perform R0 resection in all 10 cases, and pl-SMA invasion disappeared in 6 of 7 BRPC patients.We demonstrated the relationship between the angle of nerve plexus tumor invasion and treatment effect after NACRT. We could perform R0 resection in all pl-SMA invasion cases, deciding on the resection area of pl-SMA based on CT before NACRT.

Abstract
Pancreatic cancer is a dismal disease with an increasing incidence. Despite the majority of patients are not candidates for curative surgery, a subgroup of patients classified as borderline resectable pancreatic cancer can be selected in whom a sequential strategy of neoadjuvant therapy followed by surgery can provide better outcomes. Multidisciplinary approach and surgical pancreatic expertise are essential for successfully treating these patients. However, the lack of consensual definitions and therapies make the results of studies very difficult to interpret and hard to be implemented in some settings. In this article, we review the challenges of borderline resectable pancreatic cancer, the complexity of its management and controversies and point out where further research and international cooperation for a consensus strategy is urgently needed.

Abstract
Background Diagnostic imaging plays a critical role in the initial diagnosis and therapeutic monitoring of pancreatic adenocarcinoma. Over the past decade, the concept of 'borderline resectable' pancreatic cancer has emerged to describe a distinct subset of patients existing along the spectrum from resectable to locally advanced disease for whom a microscopically margin-positive (R1) resection is considered relatively more likely, primarily due to the relationship of the primary tumor with surrounding vasculature. Materials and methods This review traces the conceptual evolution of borderline resectability from a radiological perspective, including the debates over the key imaging criteria that define the thresholds between resectable, borderline resectable, and locally advanced or metastatic disease. This review also addresses the data supporting neoadjuvant therapy in this population and discusses current imaging practices before and during treatment. Results A growing body of evidence suggests that the borderline resectable group of patients may particularly benefit from neoadjuvant therapy to increase the likelihood of an ultimately margin-negative (R0) resection. Unfortunately, anatomic and imaging criteria to define borderline resectability are not yet universally agreed upon, with several classification systems proposed in the literature and considerable variance in institution-by-institution practice. As a result of this lack of consensus, as well as overall small patient numbers and lack of established clinical trials dedicated to borderline resectable patients, accurate evidence-based diagnostic categorization and treatment selection for this subset of patients remains a significant challenge. Conclusions Clinicians and radiologists alike should be cognizant of evolving imaging criteria for borderline resectability given their profound implications for treatment strategy, follow-up recommendations, and prognosis.

Abstract
Background Studies comparing upfront surgery with neoadjuvant treatment in pancreatic cancer may report only patients who underwent resection and so survival will be skewed. The aim of this study was to report survival by intention to treat in a comparison of upfront surgery versus neoadjuvant treatment in resectable or borderline resectable pancreatic cancer. Methods MEDLINE, Embase and the Cochrane Library were searched for studies reporting median overall survival by intention to treat in patients with resectable or borderline resectable pancreatic cancer treated with or without neoadjuvant treatment. Secondary outcomes included overall and R0 resection rate, pathological lymph node rate, reasons for unresectability and toxicity of neoadjuvant treatment. Results In total, 38 studies were included with 3484 patients, of whom 1738 (49·9 per cent) had neoadjuvant treatment. The weighted median overall survival by intention to treat was 18·8 months for neoadjuvant treatment and 14·8 months for upfront surgery; the difference was larger among patients whose tumours were resected (26·1 versus 15·0 months respectively). The overall resection rate was lower with neoadjuvant treatment than with upfront surgery (66·0 versus 81·3 per cent; P < 0·001), but the R0 rate was higher (86·8 (95 per cent c.i. 84·6 to 88·7) versus 66·9 (64·2 to 69·6) per cent; P < 0·001). Reported by intention to treat, the R0 rates were 58·0 and 54·9 per cent respectively (P = 0·088). The pathological lymph node rate was 43·8 per cent after neoadjuvant therapy and 64·8 per cent in the upfront surgery group (P < 0·001). Toxicity of at least grade III was reported in up to 64 per cent of the patients. Conclusion Neoadjuvant treatment appears to improve overall survival by intention to treat, despite lower overall resection rates for resectable or borderline resectable pancreatic cancer. PROSPERO registration number: CRD42016049374. Improved survival with neoadjuvant treatment

Abstract
BACKGROUND The assessment of pancreatic ductal adenocarcinoma (PDAC) response to therapy remains challenging. The objective of this study was to investigate whether changes in the tumor/parenchyma interface are associated with response. METHODS Computed tomography (CT) scans before and after therapy were reviewed in 4 cohorts: cohort 1 (99 patients with stage I/II PDAC who received neoadjuvant chemoradiation and surgery); cohort 2 (86 patients with stage IV PDAC who received chemotherapy), cohort 3 (94 patients with stage I/II PDAC who received protocol‐based neoadjuvant gemcitabine chemoradiation), and cohort 4 (47 patients with stage I/II PDAC who received neoadjuvant chemoradiation and were prospectively followed in a registry). The tumor/parenchyma interface was visually classified as either a type I response (the interface remained or became well defined) or a type II response (the interface became poorly defined) after therapy. Consensus (cohorts 1‐3) and individual (cohort 4) visual scoring was performed. Changes in enhancement at the interface were quantified using a proprietary platform. RESULTS In cohort 1, type I responders had a greater probability of achieving a complete or near‐complete pathologic response (21% vs 0%; P = .01). For cohorts 1, 2, and 3, type I responders had significantly longer disease‐free and overall survival, independent of traditional covariates of outcomes and of baseline and normalized cancer antigen 19‐9 levels. In cohort 4, 2 senior radiologists achieved a κ value of 0.8, and the interface score was associated with overall survival. The quantitative method revealed high specificity and sensitivity in classifying patients as type I or type II responders (with an area under the receiver operating curve of 0.92 in cohort 1, 0.96 in cohort 2, and 0.89 in cohort 3).

Abstract
Pancreatic cancer is the third most common cause of cancer deaths in the United States. Surgical resection with negative margins still constitutes the cornerstone of potentially curative therapy, but is possible only in 15–20% of patients at the time of initial diagnosis. Accumulating evidence suggests that the neoadjuvant approach may improve R0 resection rate in localized resectable and borderline resectable diseases, and potentially downstage locally advanced disease to achieve surgical resection, though the impact on survival is to be determined. Despite advancements in the last decade in developing effective combinational chemo-radio therapeutic options, preoperative treatment strategies, and better peri-operative care, pancreatic cancer continues to carry a dismal prognosis in the majority. Prodigious efforts are currently being made in optimizing the neoadjuvant therapy with a better toxicity profile, developing novel agents, imaging techniques, and identification of biomarkers for the disease. Advancement in our understanding of the tumor microenvironment and molecular pathology is urgently needed to facilitate the development of novel targeted and immunotherapies for this setting. In this review, we detail the current literature on contemporary management of resectable, borderline resectable and locally advanced pancreatic cancer with a focus on future directions in the field.

Abstract
The optimal management of oncological conditions is reflected by the careful interpretation of investigations for screening, diagnosis, staging, prognostication and surveillance. Serum tumour markers are examples of commonly requested tests in conjunction with other imaging and endoscopic tests that are used to help clinicians to stratify therapeutic decisions. Serum carbohydrate antigen 19-9 (CA19-9) is a key biomarker for pancreatic cancers. Although this biomarker is considered clinically useful and informative, clinicians are often challenged by the accurate interpretation of elevated serum CA19-9 levels. Recognizing the pitfalls of normal and abnormal serum CA19-9 concentrations will facilitate its appropriate use. In this review, we appraised the biomarker, serum CA19-9, and highlighted the clinical utility and limitations of serum CA19-9 in the investigation and management of pancreatic cancers.

Abstract
Background/introduction Early reports of stereotactic body radiation therapy (SBRT) for pancreatic ductal adenocarcinoma (PDAC) used single fraction, but eventually shifted to multifraction regimens. We conducted a single institution review of our patients treated with single- or multifraction SBRT to determine whether any outcome differences existed. Methods and materials Patients treated with SBRT in any setting for PDAC at our facility were included, from 2004 to 2014. Overall survival (OS), local control (LC), regional control (RC), distant metastasis (DM), and late grade 3 or greater radiation toxicities from the time of SBRT were calculated using Kaplan–Meier estimation to either the date of last follow-up/death or local/regional/distant failure. Results We identified 289 patients (291 lesions) with pathologically confirmed PDAC. Median age was 69 (range, 33–90) years. Median gross tumor volume was 12.3 (8.6–21.3) cm3 and planning target volume 17.9 (12–27) cm3. Single fraction was used in 90 (30.9%) and multifraction in 201 (69.1%) lesions. At a median follow-up of 17.3 months (IQR 10.1–29.3 months), the median survival for the entire cohort 17.8 months with a 2-year OS of 35.3%. Univariate analysis showed multifraction schemes to have a higher 2-year OS 30.5% vs. 37.5% (p = 0.019), it did not hold significance on MVA. Multifractionation schemes were found to have a higher LC on MVA (HR = 0.53, 95% CI, 0.33–0.85, p = 0.009). At 2 years, late grade 3+ toxicity was 2.5%. Post-SBRT CA19-9 was found on MVA to be a prognostic factor for OS (HR = 1.01, 95% CI, 1.01–1.01, p = 0.009), RC (HR = 1.01, 95% CI 1.01–1.01, p = 0.02), and DM (HR = 1.01, 95% CI, 1.01–1.01, p = 0.001). Conclusion Our single institution retrospective review is the largest to date comparing single and multifraction SBRT and the first to show multifraction regimen SBRT to have a higher LC than single fractionation. Additionally, we show low rates of severe late toxicity with SBRT.

Abstract
BACKGROUND Patients with borderline (BL) or locally advanced (LA) pancreatic adenocarcinoma are usually treated with primary chemotherapy (CT), followed by resection when feasible. Scanty data are available about the criteria to candidate patients to resection after CT. PATIENTS AND METHODS Between 2002 and 2016 overall 223 patients diagnosed with BL or LA pancreatic adenocarcinoma were primarily treated with Gemcitabine combination (4-drugs or nab-paclitaxel-gemcitabine) for 3-6 months followed by surgery and/or chemoradiation. Resection was carried out when radical resection could be predicted by imaging studies and intraoperative findings. The prognostic value of both pre-treatment factors and treatment response was retrospectively evaluated, searching for criteria that could improve the selection of patients for surgery. RESULTS Median survival (MS) for the whole population was 18.3 months. Surgical resection was carried out in 61 patients; MS in resected patients was significantly longer (30.0 months) as compared with 162 non-resected patients (16.5 months) (P < 0.00001). According to response criteria, 48% had a radiological partial response, 47% a stable disease and 5% a disease progression); CA19.9 response (reduction >50%) was obtained in 77.8% of patients. Among resected patients, neither pre-treatment factors, including BL/LA distinction, nor radiological response, were able to prognosticate survival differences. Survival of resected patients having no CA19.9 response was significantly lower as compared with responders (MS 15.0 versus 31.5 months, P = 0.04), and was similar to non-responders patients that did not undergo resection (MS 10.9 months, P= 0.25). Multivariate analysis carried out on the overall population, showed that Karnofsky performance status, T3-T4 status, resection and CA19.9 response were independent prognostic factors, while radiological response, BL/LA distinction and baseline CA19.9 had not significant influence on survival. CONCLUSIONS CA19.9 response may allow a better selection of patients who will benefit from resection after primary CT for BL or LA pancreatic adenocarcinoma.

Abstract
This study aims to explore the efficacy and safety of recombinant human adenovirus p53 (rAd-p53) combined with chemoradiotherapy (CRT) in the treatment of recurrent nasopharyngeal carcinoma (NPC). A total of 162 recurrent NPC patients were selected and divided randomly into the rAd-p53+CRT, CRT, and rAd-p53 groups. An electrochemical luminescence immune analyzer was used to detect serum levels of tumor markers (carcinoembryonic antigen, cancer antigen 199, and cancer antigen 153). Efficacy evaluation was in accordance with Response Evaluation Criteria in Solid Tumor. Toxicity evaluation was performed according to the WHO grading standard. A 3-year follow-up was performed. A Kaplan-Meier curve was drawn to calculate progression-free survival and the 3-year survival rate. The complete response rate and effective rate (complete response+partial response) of recurrent NPC patients in the rAd-p53+CRT group were higher than those in the CRT and rAd-p53groups. After treatment, compared with the CRT and rAd-p53 groups, the rAd-p53+CRT group had lower serum levels of carcinoembryonic antigen, cancer antigen 199, and cancer antigen 153. The incidences of leukopenia and oral mucositis in the rAd-p53+CRT group were lower than those in the CRT group, but no differences were found between the rAd-p53+CRT and rAd-p53 groups. The progression-free survival and 3-year survival rate of recurrent NPC patients in the rAd-p53+CRT group were higher than the than those in the CRT and rAd-p53 groups. Our study supports that rAd-p53 combined with CRT may provide better efficacy and lower toxicity than rAd-p53 or CRT alone for the treatment of recurrent NPC patients.

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
OPINION STATEMENT Pancreatic cancer surgery is a continuously evolving field. Despite tremendous advances in perioperative outcomes, pancreatic resection is still associated with substantial morbidity, and mortality is not nil. Institutional caseload is a well-established determinant of patient outcomes, and centralization to experienced centers is essential to the safety and oncological appropriateness of the resection. Minimally invasive approaches are increasingly applied for pancreatic resection, even in cancer patients. Nevertheless, the level of evidence in this field remains low. Minimally invasive distal pancreatectomy appears potentially beneficial towards some perioperative outcomes, although its oncological results remain incompletely studied. Data regarding perioperative and oncologic outcomes for minimally invasive pancreaticoduodenectomy (Whipple's resection) is even less mature, but suggest that similar results as the open approach can be achieved in selected, high-volume centers. Conversely, its indiscriminate adoption by inexperienced surgeons and institutions has potential deleterious effects given its steep learning curve. Newer neoadjuvant treatment protocols display enhanced ability to downstage advanced tumors, increasing candidates for potentially curative surgery. Conversely, putative benefits of neoadjuvant treatment in patients with technically resectable tumors have not been reliably demonstrated and its optimal indications remain highly controversial.

Abstract
The standard treatment of resectable pancreatic cancer is surgery followed by adjuvant chemotherapy. Due to the complication rate of pancreatic surgery and the high rate of primary irresectability, neoadjuvant concepts are increasingly used for pancreatic cancer. Neoadjuvant therapy is better tolerated than adjuvant and might decrease the surgical complication rate from pancreatic surgery. In contrast to neoadjuvant chemoradiation, the nutritional status improves during neoadjuvant chemotherapy. Also, the survival of patients who develop postoperative complications after neoadjuvant therapy is comparable to those without complications whereas the survival of patients who underwent upfront surgery and then develop surgical complications is impaired. Moreover, large data base analyses suggest a down-sizing effect and improvement of overall survival by neoadjuvant therapy. Neoadjuvant chemotherapy appears to be equally efficient in converting irresectable in resectable disease and more efficient with regard to systemic tumor progression and overall survival compared to neoadjuvant chemoradiation therapy. Despite these convincing findings from mostly small phase II trials, neoadjuvant therapy has not yet proven superiority over upfront surgery in randomized trials.

Abstract
Nowadays and given the improvement in response rate with the new schemes of treatment with chemotherapy, the interest in neoadjuvant treatment for pancreatic ductal adenocarcinoma, allowing the early application of systemic therapies, has also increased. However, treatment selection fundamentally depends on decisions taken by multidisciplinary committees due to the absence of randomized trials on this indication and because the available evidence is based primarily on small studies. The present manuscript tries to establish recommendations based on the available evidence and expert opinion to correctly select the indication, the type of treatment, as well as its duration and how to correctly follow-up patients during treatment with chemotherapy.
