Efficacy of first-line combination therapies versus gemcitabine monotherapy for advanced pancreatic cancer: a systematic review and network meta-analysis. Am J Cancer Res 2024; 14:3523-3532. [PMID: 39113858 PMCID: PMC11301282 DOI: 10.62347/tqrb4608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2023] [Accepted: 06/12/2024] [Indexed: 08/10/2024] Open
Abstract
Various first-line gemcitabine-based or fluorouracil-based combination regimens were approved in patients with advanced pancreatic cancer. Recent randomized clinical trials (RCTs) have investigated chemotherapy backbones in combination with novel investigational drugs, including chemotherapy agents or targeted drugs. However, the comparative efficacy of these different combination therapies remains limited. This systematic review and network meta-analysis aimed to assess the efficacy of first-line combination therapies for advanced pancreatic cancer. The study included 46 RCTs with 10,499 patients and 47 distinct regimens, using data sources from MEDLINE, EMBASE, Cochrane Clinical Trials, and ClinicalTrials.gov from January 1, 2010 to April 23, 2024. The primary outcomes were overall survival (OS) and progression-free survival (PFS), while secondary outcomes included overall response rate (ORR) and disease control rate (DCR). The analysis revealed that gemcitabine+nab-paclitaxel (GA), GA with platinum and fluorouracil (GA+Plat+FU), gemcitabine with fluorouracil (G+FU), G+Plt+FU, and FOLFIRINOX were associated with superior OS and PFS compared to gemcitabine monotherapy. Triplet or quadruplet polychemotherapy combinations, such as GA+Plat+FU, G+Plt+FU, and FOLFIRINOX, demonstrated better OS benefit with hazard ratios of 0.42 (95% CI, 0.26-0.68), 0.41 (95% CI, 0.24-0.71), and 0.58 (95% CI, 0.48-0.71), respectively, compared to doublet regimens like GA and G+FU, which had hazard ratios of 0.70 (95% CI, 0.59-0.82) and 0.82 (95% CI, 0.72-0.95), respectively. Notably, no targeted drugs, monoclonal antibodies, or other medications showed improved survival when added to chemotherapy backbones. These findings support the use of gemcitabine-based or fluorouracil-based triplet or quadruplet regimens for better survival outcomes in patients with advanced pancreatic cancer. Further research is warranted to explore the potential benefits of adding chemotherapy agents, such as fluorouracil, to the GA doublet regimen.

Abstract
BACKGROUND/PURPOSE This study reports the long-term results of a phase II trial evaluating the clinical efficacy of neoadjuvant gemcitabine, nab-paclitaxel, and S1 (GAS) in borderline resectable pancreatic cancer with arterial contact (BRPC-A). METHODS A multicenter, single-arm, phase II trial was conducted. Patients received six cycles of GAS and patients without progressive disease were intended for R0 resection. RESULTS Of the 47 patients, 45 (96%) underwent pancreatectomy. At the time of this analysis, all patients were updated with no loss to follow-up. A total of 30 patients died, while the remaining 17 patients were followed for a median of 68.1 months. The updated median overall survival (OS) was 41.0 months, with 2- and 5-year OS rates of 68.0% and 44.6%, respectively. Multivariate analysis in the preoperative model showed that a tumor diameter reduction rate ≥10% and a CA19-9 reduction rate ≥95% after neoadjuvant chemotherapy remained independently associated with favorable survival. In the postoperative multivariate model, no lymph node metastasis, no major surgical complications, and completion of adjuvant chemotherapy were independently associated with improved OS. CONCLUSIONS This long-term evaluation of the neoadjuvant GAS trial demonstrated the high efficacy of the regimen, suggesting that it is a promising treatment option for patients with BRPC-A.

A Phase I Study of Gemcitabine/Nab-Paclitaxel/S-1 Chemotherapy in Patients With Locally Advanced or Metastatic Pancreatic Ductal Adenocarcinoma. Oncologist 2022:6656410. [PMID: 35930304 DOI: 10.1093/oncolo/oyac146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Accepted: 06/21/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Systemic chemotherapy is the primary treatment in patients with locally advanced or metastatic pancreatic ductal adenocarcinoma (PDAC). More effective treatment options are highly awaited. The aim of this study was to evaluate the toxicity and feasibility of gemcitabine/nab-paclitaxel/S-1 (GAS) chemotherapy on a 21-day cycle in patients with locally advanced or metastatic PDAC, determine the dose-limiting toxicity (DLT) and the maximum tolerated dose (MTD) of S-1 in this regimen, and explore preliminary efficacy. METHODS Eligible patients with locally advanced or metastatic PDAC received GAS chemotherapy on a 21-day cycle. Fixed-dose nab-paclitaxel (125 mg/m2) and gemcitabine (1000 mg/m2) were given intravenously on days 1 and 8. Different doses of S-1 were given orally twice daily from day 1 to day 14 in a 3+3 dose escalation design. According to patients` body surface area, the dose-escalation design was as follows: patients with a body surface area of 1.25-1.5 m2 received S-1 40 mg/day initially and the dose was increased to 60 mg or 80 mg. Patients with a body surface area of more than 1.5 m2 received S-1 60 mg/day initially and the dose was increased to 80 mg or 100 mg. The primary endpoints were to evaluate the toxicity and determine the DLT and MTD of S-1. The secondary endpoint was to evaluate efficacy, including best objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). adverse events (AEs) were evaluated according to the NCI-CTCAE 5.0. Tumor response was assessed using the RECIST 1.1. RESULTS A total of 21 eligible patients were included. Due to the infrequence of patients with a body surface area of 1.25-1.5 m2, only 2 patients were included in cohort of S-1 40 mg. The dose-escalation for patients in this group failed to be enrolled completely. For patients with a body surface area of more than 1.5 m2, 3 DLTs in 7 patients were detected at cohort of S-1 100 mg (grade 3 thrombocytopenia with hemorrhage, grade 3 rash, and grade 3 mucositis/stomatitis). S-1 80 mg/day (body surface area: >1.5 m2) was considered to be the MTD in GAS chemotherapy on a 21-day cycle. No grade 4 AEs or treatment-related deaths were observed. The most commonly occurring hematologic AE of any grade was anemia (38.1%). The most frequent nonhematologic AEs of any grade were peripheral neuropathy (38.1%), dyspepsia (23.8%), constipation (23.8%), and alopecia (23.8%). Response assessment showed that the best ORR was 36.8% (7 of 19 patients) and the DCR was 94.7% (18 of 19 patients). The median PFS was 5.3 (95% CI, 4.6 to 6.0) months and the median OS was 10.3 (95% CI, 8.1 to 12.5) months. CONCLUSION GAS chemotherapy (21-day cycle) with nab-paclitaxel 125 mg/m2, gemcitabine 1000 mg/m2, and S-1 80 mg/day (body surface area: >1.5 m2) was found to have acceptable toxicity and significant clinical control in patients with locally advanced or metastatic PDAC. We conclude that further trials with this combination are warranted. (Trial Identifier: ChiCTR1900027833 [chictr.org]).

A phase II study of gemcitabine/nab-paclitaxel/S-1 combination neoadjuvant chemotherapy for patients with borderline resectable pancreatic cancer with arterial contact. Eur J Cancer 2021; 159:215-223. [PMID: 34781169 DOI: 10.1016/j.ejca.2021.10.012] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 10/04/2021] [Accepted: 10/11/2021] [Indexed: 01/05/2023]
Abstract
BACKGROUND The prognosis of patients with borderline resectable pancreatic cancer with arterial contact (BRPC-A) is extremely poor, and effective preoperative treatment is indispensable. We evaluated the clinical efficacy and safety of neoadjuvant chemotherapy, including gemcitabine, nab-paclitaxel and S-1 (GAS), for patients with BRPC-A. MATERIAL AND METHODS A multicentre, single-arm, phase II study was performed. Patients were administered 1000 mg/m2 gemcitabine on day 1, 125 mg/m2 nab-paclitaxel on day 1 and 60-100 mg/day S-1 on days 1-7 during a 14-day cycle. Patients were then assessed for resectability and response to treatment after six cycles. The primary end-points were 2-year overall survival (OS) rate and median OS time (trial registration: jRCTs061180045, UMIN000016630). RESULTS Forty-seven patients with BRPC-A were eligible for the present study. Six courses of neoadjuvant GAS regimen were completed in all eligible patients. The rate of grade III/IV toxicities occurred in 14 (30%) patients during the neoadjuvant GAS regimen. The response and disease control rates were 43% and 96%, respectively. Forty-five (96%) patients received potentially curative pancreatectomy, whereas two did not owing to disease progression. R0 resection was performed in 40 (86%) of 47 eligible patients. Eleven (24%) patients experienced postoperative major complications (>grade III), including one mortality. The 2-year OS rate and median OS time among 47 eligible patients were 70.1% and 41.0 months, respectively. CONCLUSIONS The neoadjuvant GAS chemotherapy regimen for BRPC-A showed good efficacy with mild toxicity, resulting in a high R0 resection rate and prolonged survival in patients with BRPC-A.

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

Abstract
The prevalence of pancreatic cancer is sharply increasing recently, which significantly increases the economic burden of the population. At present, the primary treatment of resectable pancreatic cancer is surgical resection, followed by chemotherapy with or without radiation. However, the recurrence rates remain high even after R0 resection. This treatment strategy does not distinguish undetected metastatic disease, and it is prone to postoperative complications. Neoadjuvant therapies, including neoadjuvant chemotherapy and radiotherapy, is being increasingly utilized in borderline resectable as well as resectable pancreatic cancer. This review summarized and discussed clinical trials of neoadjuvant therapy for pancreatic cancer, comparing resection rates, outcome measures, and adverse reactions between neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy.

Cancers (Basel) 2021; 13:cancers13174326. [PMID: 34503138 PMCID: PMC8430874 DOI: 10.3390/cancers13174326] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 08/18/2021] [Accepted: 08/23/2021] [Indexed: 12/20/2022] Open
Abstract
Simple Summary Due to the availability of effective combination chemotherapies such as gemcitabine/nab-paclitaxel (GNP) or FOLFIRINOX, neoadjuvant treatment of borderline resectable (BRPC) and locally advanced pancreatic cancer (LAPC) has been increasingly investigated in recent years. However, due to toxicity, FOLFIRINOX is only available for selected patients and data on GNP are scarce. The aim of this systematic review and meta-analysis, which is to our knowledge the first addressing this question, is to evaluate the value of GNP in patients with BRPC and LAPC. We provide a comprehensive overview on data of 21 studies, comprising 950 patients treated with neoadjuvant GNP. The pooled overall and R0 resection rates were 36% and 26%, respectively. Resection rates were higher in BRPC (49%) compared to LAPC (16%). With acceptable toxicity and a median overall survival rate ranging from 12 to 30 months, neoadjuvant GNP has considerable value in this setting, with more prospective trials being warranted. Abstract Therapy with gemcitabine and nab-paclitaxel (GNP) is the most commonly used palliative chemotherapy, but its advantage in the neoadjuvant setting remains unclear. Accordingly, our aim is to evaluate the impact of first-line neoadjuvant therapy with GNP in patients with borderline resectable (BRPC) and locally advanced pancreatic cancer (LAPC). A systematic search for published studies until August 2020 was performed. The primary endpoint included resection and R0 resection rates in the intention-to-treat population. Secondary endpoints were response rate, survival and toxicity. Among 21 studies, 950 patients who received neoadjuvant GNP were evaluated. Treatment with GNP resulted in surgical resection and R0 resection rates as follows: 49% (95% CI 30–68%) and 36% (95% CI 17–58%) for BRPC and 16% (95% CI 7–26%) and 11% (95% CI 5–19%) for LAPC, respectively. The objective response rates and the median overall survival (mOS) ranged from 0 to 67% and 12 to 30 months, respectively. Neutropenia (range 5–77%) and neuropathy (range 0–22%) were the most commonly reported grade 3 to 4 adverse events. Neoadjuvant chemotherapy with GNP can be performed safely and with valuable effects in patients with BRPC and LAPC. The utility of GNP in comparison to FOLFIRINOX in the neoadjuvant setting requires further investigation in prospective randomized trials.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) is still a highly fatal malignancy among the most common cancers. More powerful treatments are expecting to bring hope for patients. Biweekly gemcitabine/nab-paclitaxel/S-1 (GAS) was proved safe and effective for patients with locally advanced pancreatic cancer in Japan. The objective of this study is to evaluate the feasibility and toxicity of GAS (repeated every 3 weeks) in the treatment of locally advanced or advanced pancreatic cancer and determine the recommended dose of S-1 in this combination. METHODS This is an open-label, single-arm, and single-center phase I trial. Patients who have been diagnosed with locally advanced or advanced PDAC pathologically without previous systemic treatments will be enrolled and be treated with GAS chemotherapy every 3 weeks (nab-paclitaxel 125 mg/m 2, ivgtt, day1, 8; gemcitabine 1000 mg/m2, day1, 8; different doses of S-1 within a dose escalation scheme) until the presence of disease progression (PD), intolerable adverse events (AEs), or requirement of patients and researchers. The primary endpoints are maximum tolerated dose (MTD) and dose-limiting toxicity (DLT). The secondary endpoints include safety, objective response rate (ORR), progression-free survival (PFS) and overall survival (OS). DISCUSSION This trial will adjust the administration of GAS to make it more effective for Chinese patients, while exploring the toxicity and feasibility of this adjustment.

Survival impact of distal pancreatectomy with en bloc celiac axis resection combined with neoadjuvant chemotherapy for borderline resectable or locally advanced pancreatic body carcinoma. Pancreatology 2021; 21:564-572. [PMID: 33526385 DOI: 10.1016/j.pan.2021.01.008] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2020] [Revised: 01/12/2021] [Accepted: 01/17/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND The survival benefit associated with distal pancreatectomy with en bloc celiac axis resection (DP-CAR) for patients with borderline resectable or locally advanced pancreatic body carcinoma is controversial. The aim of this study was to evaluate the impact of DP-CAR following neoadjuvant chemotherapy on survival in patients with borderline resectable or locally advanced pancreatic body carcinoma. METHODS Medical records of patients with pancreatic ductal adenocarcinoma who underwent distal pancreatectomy (DP, n = 102) and DP-CAR following neoadjuvant chemotherapy (n = 32) between 2008 and 2019 were analyzed retrospectively. Short- and long-term outcomes were compared between the two groups. RESULTS All patients who underwent DP-CAR had tumor contact with the celiac axis. Of these, 30 patients underwent preoperative embolization of the common hepatic artery. The pretreatment tumor size of patients who underwent DP-CAR was larger (P < 0.001), and rates of blood transfusion (P = 0.003) and postoperative complications (P = 0.016) were higher in patients who underwent DP-CAR compared with patients who underwent DP. The 5-year survival rate of patients who underwent DP and DP-CAR were 50.6% and 41.1%, respectively (median survival time, 65.9 vs 37.0 months). For all 134 patients, pretreatment serum CA19-9 levels (P < 0.001), adjuvant chemotherapy (P < 0.001), and lymph node status (P = 0.035) were independent prognostic factors of overall survival by multivariate analysis. CONCLUSIONS DP-CAR following neoadjuvant chemotherapy for patients with borderline resectable or locally advanced pancreatic body carcinoma may bring the same survival impact as DP, despite increased morbidity.

Abstract
INTRODUCTION The aim of this study was to identify preoperative risk factors for poor survival in patients with resectable pancreatic ductal adenocarcinoma (PDAC) treated with upfront surgery. METHODS Medical records of 268 patients with resectable PDAC defined by resectability status who underwent upfront surgery were reviewed retrospectively. Multivariate analyses were performed to identify preoperative risk factors for recurrence-free survival (RFS) and overall survival (OS). Moreover, a binary logistic regression model was built to determine preoperative independent risk factors of 2- and 3-year recurrence and survival. RESULTS Multivariate analyses identified CA19-9 (≥100 U/mL, p < 0.001) as an independent risk factor for poor RFS, and worse performance status (1 or 2, p = 0.03), platelet:lymphocyte ratio (<150, p = 0.04), and preoperative CA19-9 (≥100 U/mL, p < 0.001) as independent risk factors for poor OS. Moreover, preoperative CA19-9 (≥100 U/mL) was the only independent risk factor identified for 2- and 3-year recurrence and survival. DISCUSSION/CONCLUSION Preoperative CA19-9 (≥100 U/mL) was the most reliable preoperative predictive factor for poor survival in resectable PDAC treated with upfront surgery. These findings warrant further clinical trials investigating efficacy of neoadjuvant therapy targeting the subset of patients with resectable PDAC who have elevated preoperative CA19-9, namely, those with high risk of poor prognosis.

Abstract
Pancreatic cancer has been becoming the second cause of cancer death in the western world, and its disease burden has increased. Neoadjuvant therapy is one of the current research hotspots in the field of pancreatic cancer, aiming to improve the surgical rate and prognosis of pancreatic cancer. Based on the latest evidence, this review discussed neoadjuvant therapy in pancreatic cancer from the following three aspects: patient selection, protocols selection of neoadjuvant therapy, and treatment response evaluation and resectability prediction. A big controversy existed on the indications of neoadjuvant treatment, but it was agreed that any patient who is likely to achieve R0 resection due to neoadjuvant therapy should be the targeted population. A variety of chemotherapy regimens were tried for neoadjuvant therapy in pancreatic cancer, and FOLFIRINOX and Nab-Paclitaxel plus Gemcitabine are two preferred regimens at present. It was challenging to evaluate treatment response and predict resectability after neoadjuvant therapy, although imaging by CT is widely used. Based on new findings of the remarkable performance of several chemotherapy regimens with or without radiotherapy, the neoadjuvant indications of pancreatic cancer have extended in recent years. However, it is still a challenge to assess the neoadjuvant treatment response and determine the timing of surgery.

Abstract
BACKGROUND The clinical implications of pre- and postoperative KRAS-mutated circulating tumor DNA (ctDNA) present in patients with pancreatic ductal adenocarcinoma (PDAC) have remained an unresolved issue. This study sought to investigate the clinical significance of pre- and postoperative ctDNA analyses and their impact on the prognosis of PDAC patients. METHODS Digital droplet polymerase chain reaction detected ctDNA in pre- and postoperative plasma samples prospectively obtained from patients with resectable and borderline-resectable PDAC. Its associations with recurrence-free survival (RFS) and overall survival (OS) were analyzed. The patients were sorted according to the presence of pre- and postoperative ctDNA, and its ability to stratify prognosis was evaluated. RESULTS The study analyzed 97 patients. Both pre- and postoperative ctDNA were detected in 9 patients, and neither was detected in 55 patients. Whereas 15 patients harbored only preoperative ctDNA, 18 patients had only postoperative ctDNA. The multivariate analysis showed that the presence of preoperative ctDNA was associated with poorer OS (P = 0.008) and that postoperative ctDNA was not associated with either RFS or OS. Survival did not differ significantly between the patients with a positive shift in ctDNA status and those without detectable pre- or postoperative ctDNA. CONCLUSIONS For the patients with PDAC, the presence of preoperative ctDNA was significantly associated poor OS, whereas postoperative ctDNA was not associated with poor survival. A positive change in ctDNA did not affect patients' survival.

Abstract
PURPOSE We conducted a phase 1 study to determine the maximum tolerated dose and the recommended dose of gemcitabine/nab-paclitaxel/S-1 combination chemotherapy in patients with unresectable pancreatic cancer. METHODS We enrolled patients aged 20 years or older with unresectable pancreatic cancer and who had not been treated with chemotherapy or radiation therapy. Gemcitabine and nab-paclitaxel were administered on days 1 and 8, and S-1 was administered orally twice daily for 2 weeks, repeated every 3 weeks. The starting dose was level 0 [gemcitabine 700 mg/m2, nab-paclitaxel 90 mg/m2, S-1 60/80/100 mg/day (< 1.25 m2/1.25-1.50 m2/ > 1.5 m2)]. Dose-limiting toxicities were determined during the first course, and a classical 3 + 3 dose finding design was planned. RESULTS From March 2018 to October 2019, 20 patients were enrolled. At dose level 0, three of six patients experienced dose-limiting toxicities; one grade 3 skin rash on day 8, and two grade 3 or 4 neutropenia on day 8. At dose level-1 (gemcitabine 600 mg/m2, nab-paclitaxel 90 mg/m2, and S-1 50/70/80 mg/day), two of twelve patients experienced dose-limiting toxicities, all of which were grade 3 neutropenia on day 8. The most frequently observed toxicity during eight courses was neutropenia. Other treatment-related adverse events were mild. Eleven out of 19 (58%) patients achieved partial response. CONCLUSION We defined the maximum tolerated dose and the recommended dose for combination therapy with gemcitabine/nab-paclitaxel/S-1 as dose level-1. Considering the observed response rate, further studies are warranted in order to determine the efficacy of this regimen (UMIN-CTR 000030007).

A Systematic Review of Prospective Studies. J Gastrointest Surg 2020; 24:2336-2348. [PMID: 32583324 DOI: 10.1007/s11605-020-04697-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Accepted: 06/11/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND In literature, percentages of pathologic complete response (pCR) in patients presenting with resectable (RES), borderline resectable (BLR) or locally advanced (LA) pancreatic cancer (PaC) after neoadjuvant treatment (NADT) are variable, ranging 0-33%. Those data come mostly from retrospective reviews of single centres. The objective of this systematic review is to assess the incidence of pCR. METHODS Following the criteria of the PRISMA statement, a literature search was conducted looking for prospective papers focusing on neoadjuvant treatment in PaC. Retrospective papers, other than ductal carcinoma histologies and trials including metastatic patients, were excluded from the present review. Data extraction was carried out by 3 independent investigators. Meta-analysis was performed with ProMeta3 Software (Internovi, 2015). PROSPERO registry: CRD42018095641. RESULTS The literature search of Embase, Cochrane and Medline with the terms "neoadjuvant OR preoperative", "pancreatic OR pancreas" and "cancer OR adenocarcinoma OR tumor" led to the identification of 3128 papers. We restricted the search to humans, last 10 years and English language articles resulting in 1158 eligible articles to review. Extended paper revision led to the inclusion of 27 papers. Complete pathologic response ranged 0-11.11%, at the meta-analysis 4% (95% CI 3-5%), in prospective studies 0-9.09% and in prospective databases 1.63-11.11%. CONCLUSIONS Pathologic complete response in pancreatic cancer is actually infrequent: high-quality studies provide a more reliable picture of neoadjuvant effects, high rates of pCR are reported in selected retrospective studies but it is overestimated.

Abstract
Pancreatic cancer (PC) is predominantly incurable and is primarily treated with gemcitabine, but drug resistance commonly develops. Thus, new medicines are needed. Ceritinib (LDK378) is a second-generation tyrosine kinase inhibitor of anaplastic lymphoma kinase (ALK) with antitumor activity in various cancers. However, studies involving ceritinib for the treatment of PC are inadequate. We analyzed the combined effects of ceritinib and gemcitabine on PC and their mechanism of action. Three PC cell lines were used to evaluate the antitumor effects of ceritinib combined with gemcitabine. We analyzed cell viability using CCK-8 assays, determined apoptosis levels through flow cytometry, and analyzed autophagy and cell signaling pathways by Western blotting and tissue array analysis with samples from xenograft models. Ceritinib strongly inhibited the proliferation of PC cells in a dose-dependent manner, induced apoptosis, and inhibited autophagy and cell migration by regulating relevant factors. Ceritinib in combination with gemcitabine exhibited significant growth inhibition and additive antitumor effects in vitro. In vivo, gemcitabine and ceritinib reduced tumor size by up to 30%. In our study, ALK was shown to be highly expressed in various PC cells and tissues. Ceritinib strongly inhibited the levels of activated ALK in PC cells with subsequent effects on the downstream mediators STAT3, AKT, and ERK. In addition, ceritinib inhibited tumor progression in xenograft models. Overall, our research shows that ceritinib inhibits the ALK signaling pathway, leading to cell growth/angiogenesis inhibition in PC and the induction of apoptosis. We recommend using ceritinib as a new treatment for PC.NEW & NOTEWORTHY These data proved that ceritinib inhibits the anaplastic lymphoma kinase signaling pathway, leading to cell growth/angiogenesis inhibition and the induction of apoptosis by inhibiting STAT3, AKT, and ERK pathway in pancreatic cancer (PC). We recommend using ceritinib as a new treatment for PC.

Reappraisal of the validity of surgery for patients with pancreatic cancer aged 80 years or older stratified by resectability status. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2019; 27:64-74.

Abstract
PURPOSE The aim of this study was to assess the validity of surgical resection for patients with pancreatic ductal adenocarcinoma (PDAC) aged ≥80 years stratified by resectability status. METHODS Medical records of 245 patients with resectable (R) and 169 with borderline resectable/unresectable (BR/UR) PDAC were reviewed retrospectively. Of the total of 414 patients, 56 (14%) were ≥80 years. The prognostic impact of age ≥80 years was analyzed with stratification by resectability status. RESULTS No significant difference was found in the incidence of major complications between patients aged ≥80 versus <80 years (12% vs. 16% respectively; P = 0.53). However, patients aged ≥80 years were significantly less likely to receive adjuvant gemcitabine + S-1 chemotherapy than those <80 years (39% vs. 83%, respectively; P < 0.001). Multivariate analyses identified age ≥80 years as an independent risk factor for poor survival in the BR/UR group (P = 0.01), whereas it did not affect survival in the R group. CONCLUSION Patients aged ≥80 years had a similar prognosis to <80 years in R PDAC, whereas they had significantly worse prognosis in BR/UR PDAC. These findings suggest that surgical resection for patients with PDAC aged ≥80 years is validated in R PDAC, whereas its survival benefit might be limited in BR/UR PDAC.

Prognostic Significance of Lymph Node Metastasis and Micrometastasis Along the Left Side of Superior Mesenteric Artery in Pancreatic Head Cancer. J Gastrointest Surg 2019; 23:2100-2109. [PMID: 31410820 DOI: 10.1007/s11605-019-04359-x] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Accepted: 08/01/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUNDS AND OBJECTIVES Although metastasis in lymph nodes along the left side of superior mesenteric artery (SMA-LNs-lt) is sometimes found, survival benefit of SMA-LN-lt dissection for pancreatic head cancer is still unclear. The purpose of this study is to evaluate the prognostic significance of SMA-LN-lt metastasis and micrometastasis. METHODS A total of 166 patients with pancreatic head cancer who underwent pancreatectomy with lymphadenectomy including SMA-LNs-lt between 2002 and 2017 were reviewed retrospectively. Micrometastasis was evaluated by immunohistochemistry. RESULTS Twenty patients (12%) had SMA-LN-lt metastasis detected by hematoxylin and eosin (HE) staining, and eight patients (5%) had micrometastasis. Patients with SMA-LN-lt HE-positive or micrometastasis group experienced significantly shorter overall survival (OS) than those without (p = .015). In multivariate analysis, SMA-LN-lt HE-positive or micrometastasis (p = .034), portal vein resection (p = .002), histologic grade 2/3 (p = .046), LN metastasis (p = .002), and lack of adjuvant chemotherapy (p < .001) were independent risk factors. Within a subset of SMA-LN-lt HE-positive or micrometastasis group, lack of adjuvant chemotherapy (p = .003) was the independent poor prognostic factor. CONCLUSIONS In pancreatic head cancer, the rate of SMA-LN-lt HE-positive and micrometastasis was found in 12% and 5%, respectively. Adjuvant chemotherapy may contribute to improvement of prognosis in patients with LN metastasis including SMA-LN-lt metastasis and micrometastasis.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) remains one of the most aggressive tumors, with a low rate of survival, likely due to the tendency of the tumor for early local and distant spread. Pancreatic cancer accounts for about 3% of all cancers in the US and about 7% of all cancer deaths. Surgical resection still represents the best curative treatment for PDAC, although only 10–20% of patients are upfront resectable at diagnosis, 50% has metastatic disease and 35% locally advanced cancer. The 5-year overall survival (OS) after curative resection is limited to 20%. Moreover among patients who undergo surgery, 30% develop early recurrence while most of them will eventually relapse. The risk of early failure after surgery could be associated with inadequate preoperative radiological staging, lack of radical surgery and differences in tumor aggressiveness. In recent years, more accurate patient categorization due to sophisticated imaging tools and techniques increase the survival rate while neoadjuvant treatment can help surgeons select patients who will benefit most from surgery. Neoadjuvant therapy includes chemotherapy alone, chemoradiotherapy, chemotherapy with chemoradiation and targeted therapies. The aim of this review is to present the available data concerning the management of patients with borderline PDAC.

Abstract
BACKGROUND AND OBJECTIVES The aim of this study was to investigate the prognostic impact of postoperative complications after pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) stratified by resectability status. METHODS Medical records of 226 patients with pancreatic head carcinoma who underwent PD, including 115 with resectable (R) and 111 with borderline resectable/unresectable (BR/UR) PDAC, were reviewed retrospectively. Major complications were defined as grade III or IV based on the Clavien-Dindo classification system. The prognostic impact of major complications on overall survival (OS) was analyzed using univariate and multivariate analyses with stratification by resectability status. RESULTS A multivariate analysis in the BR/UR group identified R1 resection (P = 0.03), T 3/4 stage (P = 0.03), and incidence of major complications (P = 0.03) as independent risk factors for poor survival, whereas major complications did not affect survival in the R group. Initiation of adjuvant gemcitabine plus S-1 chemotherapy occurred significantly less frequently for patients with major complications than for those without major complications in the BR/UR group (P = 0.02). CONCLUSION A negative prognostic impact of postoperative major complications after PD was observed in patients with BR/UR PDAC, whereas the prognostic impact was unclear in patients with R PDAC.
