Impact of neoadjuvant chemotherapy and stereotactic body radiation therapy (SBRT) on R0 resection rate for borderline resectable and locally advanced pancreatic cancer. HPB (Oxford) 2021; 23:1072-1083. [PMID: 33277184 DOI: 10.1016/j.hpb.2020.11.004] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2020] [Revised: 10/05/2020] [Accepted: 11/09/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND The role of neoadjuvant stereotactic body radiation therapy (SBRT) in patients with borderline resectable pancreas cancer (BRPC) and locally advanced pancreas cancer (LAPC) remains controversial. METHODS We retrospectively evaluated BRPC and LAPC patients treated at our institution who underwent 2-3 months of chemotherapy followed by SBRT to a dose of 30-33 Gy. Overall survival (OS) and recurrence-free survival (RFS) were estimated and compared by Kaplan-Meier and log-rank methods. RESULTS We identified 103 (85 BRPC and 18 LAPC) patients treated per our neoadjuvant paradigm between 2011 and 2018, with resectability based on NCCN definitions. Median follow up was 25 months. Of patients completing neoadjuvant therapy, 73 (71%) underwent definitive resection. Seventy-one (97%) patients with definitively resected tumors had R0 resection and 5 (7%) had a complete pathologic response CR to neoadjuvant therapy. The median overall survival (OS) of the cohort was 24 months. Those with a complete or marked pathologic response had significantly better OS than those with a moderate response (41 vs 24 months, p < 0.02) and patients unable to undergo definitive surgery (17 months, p < 0.0003). Six resected patients experienced grade ≥3 surgical complications. CONCLUSIONS Neoadjuvant chemotherapy and SBRT are associated with promising pathologic response rates and R0 resection rates, with acceptable perioperative morbidity.

Abstract
Currently, the combination of 5-fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) is the standard therapy for metastatic pancreatic cancer. In recent years, FOLFIRINOX-based neoadjuvant therapy for locally advanced pancreatic cancer (LAPC) has been gaining an increasing amount of attention, owing to its ability to reduce disease stage and transform LAPC to borderline resectable or even resectable pancreatic cancer. Accordingly, we aimed to evaluate the efficacy of first-line FOLFIRINOX chemotherapy in patients with LAPC.We searched PubMed, Embase, and Cochrane Library from the time of establishment till January 1, 2020 and included studies focusing on LAPC patients who received FOLFIRINOX as first-line neoadjuvant treatment. The primary outcomes were: resection rate and radical (R0) resection rate while the secondary outcomes were: objective response rate, overall survival, progression-free survival, and rate of grade 3 to 4 adverse events. The meta package for R 3.6.2 was used for heterogeneity and publication bias testing.Twenty-one studies, including 653 patients with LAPC, were selected. After treatment with FOLFIRINOX, the resection rate was 26% (95% confidence interval [CI] = 20%-32%, I2 = 61%) and R0 resection rate was 88% (95% CI = 78%-95%, I2 = 62%). The response rate was 34% (95% CI = 25%-43%, I2 = 56%). The median overall survival and progression-free survival durations ranged from 10.0 to 32.7 months and 3.0 to 25.3 months, respectively. The observed grade 3 to 4 adverse events were neutropenia (20.0 per 100 patients, 95% CI = 14%-27%, I2 = 75%), febrile neutropenia (7.0 per 100 patients, 95% CI = 5%-9%, I2 = 42%), thrombocytopenia (6.0 per 100 patients, 95% CI = 5%-8%, I2 = 27%), nausea/vomiting (7.0 per 100 patients, 95% CI = 7%-12%, I2 = 76%), diarrhea (10.0 per 100 patients, 95% CI = 8%-12%, I2 = 38%), and fatigue (9.0 per 100 patients, 95% CI = 7%-11%, I2 = 43%).FOLFIRINOX-based neoadjuvant chemotherapy has the potential to improve the rates of resection, R0 resection, and median OS in LAPC. Our results require further validation in large, high-quality randomized controlled trials.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive gastrointestinal malignancy with a poor 5-year survival rate. Accurate staging of PDAC is an important initial step in the development of a stage-specific treatment plan. Different staging systems/consensus statements convened by different societies and academic practices are currently used. The most recent version of the American Joint Committee on Cancer (AJCC) tumor/node/metastases (TNM) staging system for PDAC has shifted its focus from guiding management to assessing prognosis. In order to preoperatively define the resectability of PDAC and to guide management, additional classification systems have been developed. The National Comprehensive Cancer Network (NCCN) guidelines, one of the most commonly used systems, provide recommendations on the management and the determination of resectability for PDAC. The NCCN divides PDAC into three categories of resectability based on tumor-vessel relationship: 'resectable,' 'borderline resectable,' and 'unresectable'. Among these, the borderline disease category is of special interest given its evolution over time and the resulting variations in the definition and the associated recommendations for management between different societies. It is important to be familiar with the evolving criteria, and treatment and follow-up recommendations for PDAC. In this article, the most current AJCC staging (8th edition), NCCN guidelines (version 2.2019-April 9, 2019), and challenges and controversies in borderline resectable PDAC are reviewed.

Abstract
Aims and background To evaluate the efficacy and tolerability of a new treatment approach including induction chemotherapy (CT) and concurrent chemoradiotherapy (CRT) in unresectable, locally advanced pancreatic cancer (LAPC). Patients and methods Twenty-four patients with LAPC were enrolled in the study. They first received induction CT consisting of 5-fluorouracil (5FU) (500 mg/m2) and gemcitabine (1000 mg/m2), which were given weekly for 3 weeks of every 4. Patients showing a response or disease stabilization after 2 cycles of induction CT received CRT consisting of external beam radiotherapy (50.4-54 Gy in fractions of 1.8 Gy/day) and gemcitabine (350 mg/m2, weekly for 6 weeks). Patients without disease progression received 2 additional cycles of CT consisting of 5FU plus gemcitabine with the same doses and schedule as given in the induction CT. Results After the end of the study, 2 (8%) and 5 (21%) patients showed complete and partial responses, respectively. Five patients (21%) had disease stabilization. The grade 3 and 4 toxicities associated with CT were neutropenia (21%) and thrombocytopenia (4%). The grade 3 and 4 toxicities occurring in patients who received CRT were neutropenia (24%), thrombocytopenia (24%), diarrhea (18%), and nausea (12%). The median progression-free survival for all patients was 6 months (95% CI, 3.6-8.4), and the median overall survival was 11 months (95% CI, 8.16-13.84). Conclusions The CRT approach of this study is moderately active and has an acceptable toxicity profile. However, the incor-poration of combination CT into CRT at the present schedule could not produce any additional benefit over CRT alone. Newer agents with more systemic activity are clearly warranted.

Characterization of Novel Murine and Human PDAC Cell Models: Identifying the Role of Intestine Specific Homeobox Gene ISX in Hypoxia and Disease Progression. Transl Oncol 2019; 12:1056-1071.

Abstract
Therapy failure and metastasis-associated mortality are stumbling blocks in the management of PDAC in patients. Failure of therapy is associated to intense hypoxic conditions of tumors. To develop effective therapies, a complete understanding of hypoxia-associated changes in genetic landscape of tumors during disease progression is needed. Because artificially immortalized cell lines do not rightly represent the disease progression, studying genetics of tumors in spontaneous models is warranted. In the current study, we generated a spectrum of spontaneous human (UM-PDC1; UM-PDC2) and murine (HI-PanL, HI-PancI, HI-PanM) models representing localized, invasive, and metastatic PDAC from a patient and transgenic mice (K-rasG12D/Pdxcre/Ink4a/p16-/). These spontaneous models grow vigorously under hypoxia and exhibit activated K-ras signaling, progressive loss of PTEN, and tumorigenicity in vivo. Whereas UM-PDC1 form localized tumors, the UM-PDC2 metastasize to lungs in mice. In an order of progression, these models exhibit genomic instability marked by gross chromosomal rearrangements, centrosome-number variations, Aurora-kinase/H2AX colocalization, loss of primary cilia, and α-tubulin acetylation. The RNA sequencing of hypoxic models followed by qRT-PCR validation and gene-set enrichment identified Intestine-Specific Homeobox factor (ISX)–driven molecular pathway as an indicator PDAC aggressivness. TCGA-PAAD clinical data analysis showed high ISX expression correlation to poor survival of PDAC patients, particularly women. The functional studies showed ISX as a regulator of i) invasiveness and migratory potential and ii) VEGF, MMP2, and NFκB activation in PDAC cells. We suggest that ISX is a potential druggable target and newly developed spontaneous cell models are valuable tools for studying mechanism and testing therapies for PDAC.

Abstract
Background: The treatment of abdominal wall metastasis presents a challenge, because resection can be followed by poor healing and external radiotherapy is associated with serious adverse events. This study aimed to evaluate the efficacy and safety of interstitial 125I seed implantation under ultrasound (US) guidance for treating abdominal wall metastasis. Materials and Methods: The cases of 21 patients with 28 abdominal wall metastases who received brachytherapy with 125I seeds at the department from August 2010 to March 2015 were retrospectively reviewed. 125I seeds were implanted in the abdominal wall lesions under US guidance and with the help of a treatment planning system. Follow-up was performed using computed tomography at 1 d and at 3, 6, and 12 months after implantation. The lymphocyte count before the surgery was compared with the 3-month postoperative count. The main indicators observed were changes in tumor size, side effects, and complications. Results: All 21 patients were successfully treated with 125I seed implantation under US guidance. The median follow-up since 125I seed implantation was 15 months (range 6-23 months). The response rates and local tumor control after 3, 6, and 12 months were 78.6% and 89.3%, 64.3% and 85.7%, and 52.4% and 71.4%, respectively. The mean preoperative lymphocyte count was 0.262 ± 0.117 × 109/L, which did not differ significantly from the postoperative count, which was 0.259 ± 0.094 × 109/L (p = 0.122). Procedure-related complications included fever, bleeding, and pain, but all these were Grade 1-2. No severe side effects or complications were noted. Conclusions: Percutaneous interstitial implantation of 125I seeds under US guidance is safe and feasible for abdominal wall metastases. However, its long-term efficacy requires further investigation.

Abstract
This work considers Phase I cancer dual-agent dose-escalation clinical trials in which one of the compounds is an immunotherapy. The distinguishing feature of trials considered is that the dose of one agent, referred to as a standard of care, is fixed and another agent is dose-escalated. Conventionally, the goal of a Phase I trial is to find the maximum tolerated combination (MTC). However, in trials involving an immunotherapy, it is also essential to test whether a difference in toxicities associated with the MTC and the standard of care alone is present. This information can give useful insights about the interaction of the compounds and can provide a quantification of the additional toxicity burden and therapeutic index. We show that both, testing for difference between toxicity risks and selecting MTC can be achieved using a Bayesian model-based dose-escalation design with two modifications. Firstly, the standard of care administrated alone is included in the trial as a control arm and each patient is randomized between the control arm and one of the combinations selected by a model-based design. Secondly, a flexible model is used to allow for toxicities at the MTC and the control arm to be modeled directly. We compare the performance of two-parameter and four-parameter logistic models with and without randomization to a current standard of such trials: a one-parameter model. It is found that at the cost of a small reduction in the proportion of correct selections in some scenarios, randomization provides a significant improvement in the ability to test for a difference in the toxicity risks. It also allows a better fitting of the combination-toxicity curve that leads to more reliable recommendations of the combination(s) to be studied in subsequent phases.

Feasibility of 2D-conformal radiotherapy for pancreatic carcinoma. Oncol Lett 2018; 16:5939-5945. [PMID: 30333867 PMCID: PMC6176419 DOI: 10.3892/ol.2018.9389] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2018] [Accepted: 07/25/2018] [Indexed: 11/06/2022] Open
Abstract
The purpose of the present study was to propose an optimized 2D technique (2D-conformal) for radiotherapy (RT) of pancreatic cancer (CaP). This technique is based on double simulation which resolves the problems of radiographic image distortion. Five patients with locally advanced CaP were identified and enrolled. Treatment planning was simulated in 3 different ways: Two dimensional-standard (2D-SRT), 2D-conformal (2D-CRT), and three dimensional-conformal (3D-CRT) techniques for 10 MV LINAC. Simulation for a cobalt machine was also performed using only the 2D techniques. 2D-SRT technique was planned with fields definition based on anatomical landmarks (bone and duodenum). 3D-CRT was planned with standard virtual simulation technique, and 3D dose evaluation and optimization. 2D-CRT technique was based on manual information transfer from a diagnostic CT-scan to simulation radiograms. To eliminate the X-ray image distortion, a double simulation was employed and the profile of the GTV was delineated on radiographs bearing the simulator isocenter into the target center. Concerning target irradiation of either LINAC (10 MV) or cobalt source, the PTV constraints (ICRU 62) were met in all patients (Dmin >95%, Dmax <107%) with all techniques (2D-SRT, 3D-CRT, 2D-CRT). For organs at risk irradiation, in terms of Dmax to both duodenum and spinal cord, similar results were recorded with all techniques using the LINAC (10 MV). Liver and kidneys Dmean gradually improved from 2D-SRT to 2D-CRT and 3D-CRT. The 2D-CRT compared to 2D-SRT technique, halved the average dose to the liver and reduced to about 1/3 the average dose to the kidneys. With the cobalt source, using the 2D-CRT produced a reduction of Dmean to the kidneys (median from 30.7 to 16.9%) and liver (median from 33.4 to 22.3%) compared to 2D-SRT. This analysis showed better planning results in RT treatment of CaP while using a 2D-CRT compared to 2D-SRT technique and therefore presents an example for optimized 2D RT use.

Abstract
Despite recent advances in radiotherapy, a majority of patients diagnosed with pancreatic cancer (PC) do not achieve objective responses due to the existence of intrinsic and acquired radioresistance. Identification of molecular mechanisms that compromise the efficacy of radiation therapy and targeting these pathways is paramount for improving radiation response in PC patients. In this review, we have summarized molecular mechanisms associated with the radio-resistant phenotype of PC. Briefly, we discuss the reversible and irreversible biological consequences of radiotherapy, such as DNA damage and DNA repair, mechanisms of cancer cell survival and radiation-induced apoptosis following radiotherapy. We further describe various small molecule inhibitors and molecular targeting agents currently being tested in preclinical and clinical studies as potential radiosensitizers for PC. Notably, we draw attention towards the confounding effects of cancer stem cells, immune system, and the tumor microenvironment in the context of PC radioresistance and radiosensitization. Finally, we discuss the need for examining selective radioprotectors in light of the emerging evidence on radiation toxicity to non-target tissue associated with PC radiotherapy.

Abstract
Patients with locally advanced unresectable pancreatic cancer (LAUPC) have a poor prognosis. In addition their quality of life impaired by cancer pain and biliary tract infections. Therefore, multimodality therapy and selection of optimal treatment methods are essential for achieving prolonged survival. The present study investigated the significance of using hyperthermia concurrently with multimodality therapy to improve treatment outcomes in patients with LAUPC. In total, 13 patients receiving concurrent hyperthermia and chemoradiotherapy (HCR) or chemoradiotherapy (CR) alone for LAUPC between 2002 and 2013 were analyzed retrospectively. Of the 13 patients, 5 received concurrent HCR and 8 received CR. The chemotherapy regimens were 5-fluorouracil (5-FU) in 5 patients and gemcitabine hydrochloride (GEM) in the other 8. Patients who gave consent for hyperthermia treatment received GEM plus CR. The median overall survival period for all patients was 12 months and the 1-year survival rate was 55%; the corresponding values were 12 months and 57% in the GEM CR group, and 15 months and 80% in the HCR group. Univariate analyses was perfomed to identify factors predicting recurrence after treatment. The potential prognostic factors analyzed were: Age, sex, performance status, location, tumor size, the tumor marker CA 19-9, total radiation dose, chemotherapy and hyperthermia. Univariate analysis for factors associated with outcomes revealed a significant difference favoring the HCR group [relative risk=15.97 (95% confidence interval: 12.87-19.83) P=0.021]. In conclusion, hyperthermia merits active recommendation to pancreatic cancer patients who have a positive attitude toward this treatment and whose performance status is satisfactory.

Abstract
To better guide the development and optimization of radiotherapy planning, to reduce the incidence of radiation reactions, and to improve the quality of life of the patients with pancreatic cancer using radiotherapy, we conducted this study to explore the dosimetric parameters that predict the risk of gastrointestinal (GI) toxicity with hypofractioned radiotherapy for pancreatic cancer. Between January 2014 and January 2015, the medical records of 68 patients with pancreatic cancer who underwent helical tomotherapy at the Air Force General Hospital were analyzed. The doses delivered to the planning target volume, clinical target volume, and gross tumor volume-internal gross tumor volume of the primary pancreatic lesions were 50, 60, and 70-80 Gy in 15-20 fractions, respectively. GI toxicity was scored according to version 4.0 of the National Cancer Institute Common Terminology Criteria for Adverse Events. The stomach and duodenum were contoured separately to determine the dose-volume histogram parameters. Univariate and multivariate analyses were adopted to identify clinical and physical risk factors associated with GI toxicity. The median follow-up was 9 months (range: 4-16 months). Eighteen patients had grade II acute GI toxicity, one patient had grade III acute GI toxicity, 17 patients had grade II late GI toxicity, and one patient had grade III late GI toxicity. On univariate analysis, the volume, the average dose D mean, the maximum dose to 1, 3, 5, and 10 cm(3) of the stomach and duodenum (D1, D3, D5, and D10), and the relative volumes receiving 5-40 Gy (V5-V40), and the absolute volumes receiving 5-45 Gy (aV5-aV45) of the duodenum were significantly associated with grade II or higher GI toxicity (P<0.05). On multivariate analysis, aV45 of the duodenum was an independent predictor for grade II or higher GI toxicity (P=0.031). The receiver operating characteristic analysis also showed that an aV45 of 0.5 cm(3) was the optimal threshold to predict GI toxicity for the entire cohort. Our findings indicate that many dosimetric parameters of the duodenum correlate with grade II or higher GI toxicity. To reduce GI toxicity, the absolute volume of the irradiated duodenum should be reduced.

Abstract
BACKGROUND AND PURPOSE Nelfinavir can enhance intrinsic radiosensitivity, reduce hypoxia and improve vascularity. We conducted a phase II trial combining nelfinavir with chemoradiotherapy (CRT) for locally advanced inoperable pancreatic cancer (LAPC). MATERIALS AND METHODS Radiotherapy (50.4Gy/28 fractions; boost to 59.4Gy/33 fractions) was administered with weekly gemcitabine and cisplatin. Nelfinavir started 3-10days before and was continued during CRT. The primary end-point was 1-year overall survival (OS). Secondary end-points included histological downstaging, radiological response, 1-year progression free survival (PFS), overall survival (OS) and treatment toxicity. An imaging sub-study (n=6) evaluated hypoxia ((18)F-Fluoromisonidazole-PET) and perfusion (perfusion CT) during induction nelfinavir. RESULTS The study closed after recruiting 23 patients, due to non-availability of Nelfinavir in Europe. The 1-year OS was 73.4% (90% CI: 54.5-85.5%) and median OS was 17.4months (90% CI: 12.8-18.8). The 1-year PFS was 21.8% (90% CI: 8.9-38.3%) and median PFS was 5.5months (90% CI: 4.1-8.3). All patients experienced Grade 3/4 toxicity, but many were asymptomatic laboratory abnormalities. Four of 6 patients on the imaging sub-study demonstrated reduced hypoxia and increased perfusion post-nelfinavir. CONCLUSIONS CRT combined with nelfinavir showed acceptable toxicity and promising survival in pancreatic cancer.

Abstract
Pancreatic cancer is an aggressive cancer that continues to have single-digit 5-year mortality rates despite advancements in the field. Surgery remains the only curative treatment; however, most patients present with late-stage disease deemed unresectable, either due to extensive local vascular involvement or the presence of distant metastasis. Resection guidelines that include a borderline resectable group, as well as advancements in neoadjuvant chemotherapy and radiation that improve resectability of locally advanced disease, may improve outcomes for patients with more invasive disease. Multi-agent chemotherapy regimens fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) and nab-paclitaxel with gemcitabine improved response rates and survival in metastatic pancreatic cancer and are now being used in earlier stages for patients with localized potentially resectable and unresectable disease, with goals of downstaging tumors to allow margin-negative resection and reducing systemic recurrence. Chemoradiotherapy, although still controversial for both resectable and unresectable pancreatic cancer, is being used in the context of contemporary chemotherapy backbone regimens, and novel radiation techniques such as stereotactic body frame radiation therapy (SBRT) are studied on the premise of maintaining or improving efficacy and reducing treatment duration. Patient selection for optimal treatment designation is currently provided by multidisciplinary tumor boards, but biomarker discovery, in blood, tumors, or through novel imaging, is an area of intense research. Results to date suggest that some patients with unresectable disease at the outset have survival rates as good as those with initially resectable disease if able to undergo surgical resection. Long-term follow-up and improved clinical trials options are needed to determine optimal treatment modalities for patients with localized pancreatic cancer.

Abstract
AIM: To evaluate the clinical effects of stereotactic conformal radiotherapy combined with gemcitabine in patients with locally advanced pancreatic carcinoma.
METHODS: A total of 118 patients with unresectable locally advanced pancreatic carcinoma were divided into two groups to receive either radiotherapy combined with gemcitabine (group A, 56 cases) or radiotherapy alone (group B, 62 cases). The standard dose of stereotactic conformal radiotherapy prescribed was 35-45 Gy to the 50%-65% isodose curve. The total dose was delivered over 10-13 d with a fraction dose of 2.8-3.5 Gy and 6 fractions per week. Concomitant chemotherapy started at the first day of radiotherapy: gemcitabine at a dose of 600 mg/m2 was given on days 1 and 8, and adjuvant chemotherapy was administered three weeks after radiotherapy at a dose of gemcitabine 1000 mg/m2 on days 1 and 8, 21 days per cycle, for 4-6 cycles continuously.
RESULTS: The patients underwent CT or MR examination 2 mo after 2 treatment. The tumor response rate of group A was 67.8% (38/56). Median survival time was 12.8 mo (range, 4-70 mo). The overall 1-year and 2-year survival rates were 58.9% (33/56) and 28.6% (16/56), respectively. Main side effects included leukopenia, thrombocytopenia, nausea and vomiting. The tumor response rate of group B was 30.6% (19/62). Median survival time was 8.5 mo (range, 5-56 mo). The overall 1-year and 2-year survival rates were 33.9% (21/66) and 12.9% (8/62), respectively. Main side effects were leukopenia and thrombocytopenia. Both the short-term and long-term therapeutic effects were better in the combination group than in the radiotherapy alone group.
CONCLUSION: Gemcitabine combined with stereotactic conformal radiotherapy is effective and safe in the treatment of patients with locally advanced pancreatic carcinoma.

Abstract
Background Radio-chemotherapy is one of the steps of multidisciplinary management in locally advanced pancreatic cancer. The Epidermal Growth Factor Receptor (EGFR) plays an important role in the disease pathway. The purpose of this prospective study is to evaluate the feasibility and the efficacy of radiotherapy in combination with gemcitabine and EGFR targeting therapy for patients with locally advanced disease. Materials and methods From November 2008 through January 2012, 34 patients were included in this study. In all cases an accurate pre-treatment staging including CT scan, Endoscopic Ultra-Sonography (EUS), 18F - fluorodeoxyglucose (18F-FDG) PET-CT and laparoscopy with peritoneal washing was performed. External beam radiation was delivered with a total dose of 50.4 Gy (1.8 Gy per fraction). Patients were treated using 3D- conformal radiotherapy, and the clinical target volume was the primary tumor and involved lymph nodes. Gemcitabine 300 mg/m2 and Cetuximab were given weekly during radiation therapy. Results Ten patients (29.4 %) were excluded from the protocol because of the evidence of metastatic disease at the pre-treatment staging. Three patients refused radiochemotherapy. Twenty-one patients completed the therapy protocol. During the combined therapy grade 3–4 toxicities observed were only haematological (leukopenia 47,6 %, trombocytopenia 4.8 %, elevated gamma-GT 23.8 %, elevated alkaline phosphatase 4,8 %). Non-haematological toxicity grade 3–4 was never reported. Post-treatment workup showed partial response in five patients (24 %), stable disease in 11 patients (52 %) and disease progression in 5 patients (24 %). Two-year Local Control was 49 % (median, 18.6 months), 2-year Metastases Free Survival was 24 % (median, 10.8 months). One and two-year Overall Survival were 66 % and 28 % respectively, with a median survival time of 15.3 months. Conclusions The combination of cetuximab and gemcitabine with concurrent radiation therapy provides a feasible and well tolerated treatment for locally advanced pancreatic cancer. Patients’ selection is crucial in order to treat patients appropriately.

Abstract
Purpose The optimal treatment strategy for locally advanced pancreatic cancer (LAPC), particularly the role of concurrent chemoradiotherapy (CCRT), remains debatable. We compared the clinical outcomes of CCRT and palliative chemotherapy alone (CA) in patients with unresectable LAPC. Materials and Methods Patients with LAPC who were consecutively treated between 2003 and 2010 were included. Resectability was evaluated according to National Comprehensive Cancer Network ver. 1.2012. The clinical outcomes for each treatment group (CCRT vs. CA) were evaluated retrospectively. Results Sixty-three patients (58.9%) and 44 patients (41.1%) were treated with CCRT and CA, respectively. The CCRT cohort included patients who were treated with CCRT with or without chemotherapy backbone (CCRT alone, induction chemotherapy-CCRT, CCRT-maintenance chemotherapy, and induction-CCRT-maintenance chemotherapy). Median progression-free survival (PFS) and overall survival (OS) of all patients were 7.2 months and 13.1 months. PFS of the CCRT and CA groups was 9.0 months and 4.4 months, respectively (p=0.020). OS of the CCRT and CA groups was 15.4 months and 9.3 months, respectively (p=0.011). In multivariate analysis, the adjusted hazard ratio of CCRT was 0.536 (p=0.003) for OS and 0.667 (p=0.078) for PFS. Although the pattern of failure was similar in the CCRT and CA groups, the times to both local and distant failure were significantly longer in the CCRT group. Conclusion In patients with unresectable LAPC, those who underwent CCRT during their entire treatment courses had longer OS than patients treated with chemotherapy alone.

Abstract
PURPOSE Limited data are available to guide neoadjuvant treatment of borderline resectable (BRPC) and locally advanced (LAPC) pancreatic cancer. MATERIAL AND METHODS We updated our institutional outcomes with a neoadjuvant chemotherapy and stereotactic body radiotherapy (SBRT) approach. An IRB-approved analysis was performed of all BRPC and LAPC patients treated with our departmental treatment protocol. After staging, medically fit patients underwent chemotherapy for 2-3 months, with regimen at the discretion of the treating medical oncologist. Patients then received SBRT delivered in five consecutive daily fractions with median total radiation doses of 30 Gy to tumor and 40 Gy dose painted to tumor-vessel interfaces. This was followed by restaging imaging for possible resection. Overall survival (OS), event free survival (EFS), and locoregional control (LRC) rates were estimated and compared by Kaplan-Meier and log-rank methods. RESULTS We identified 159 patients, 110 BRPC and 49 LAPC, with 14.0 months median overall follow-up. The resection and margin negative (R0) rate for BRPC patients who completed neoadjuvant therapy was 51% and 96%, respectively. Estimated median OS was 19.2 months for BRPC patients and 15.0 months for LAPC patients (p = 0.402). Median OS was 34.2 months for surgically resected patients versus 14.0 months for unresected patients (p < 0.001). Five of 21 (24%) LAPC patients receiving FOLFIRINOX chemotherapy underwent R0 resection. In LAPC, FOLFIRINOX recipients underwent R0 resection more often than other chemotherapy recipients (5 of 21 vs. 0 of 28, p = 0.011). There was a trend for improved survival in those resected LAPC patients (p = 0.09). For those not undergoing resection, one year LRC was 78%. Any grade ≥ 3 potentially radiation-related toxicity rate was 7%. CONCLUSIONS These data underscore the feasibility, safety, and effectiveness of neoadjuvant SBRT and chemotherapy for BRPC and LAPC.

Abstract
Radioresistance has become a challenge in the treatment of pancreatic cancer, which limits the efficacy and outcomes of radiotherapy in clinical treatment. Autophagy, recognized as an adaptive response to cell stress, has recently been involved in the radioresistance of cancer cells. MicroRNAs (miRNAs) are also involved in the radioresistance of pancreatic cancer cells. In the present study, we established a radioresistant pancreatic cancer cell line and found that miRNA-216a was significantly downregulated whereas the autophagy activity was increased as compared with the control. Forced expression of miR-216a was found to inhibit the expression of beclin-1, a critical autophagic gene, as well as autophagy. Using bioinformatics analysis and the dual-luciferase reporter gene assay, we found that miR-216a directly interacted with 3'-untranslated region (UTR) of beclin-1. Furthermore, the forced expression of miR‑216a inhibited cell growth and colony formation ability and promoted the cell apoptosis of radioresistant pancreatic cancer cells in response to irradiation. By contrast, overexpression of beclin-1 abrogated the effects of miR-216a. Furthermore, miR-216a sensitized xenograft tumor to irradiation treatment and inhibited irradiation-induced autophagy by regulating beclin-1. Collectively, the results demonstrated that miR‑216a enhanced the radiosensitivity of pancreatic cancer cells by inhibiting beclin-1-mediated autophagy, suggesting a promising molecular target for improving the radiotherapy of pancreatic cancer.

Gene-mediated cytotoxic immunotherapy as adjuvant to surgery or chemoradiation for pancreatic adenocarcinoma. Cancer Immunol Immunother 2015; 64:727-36. [PMID: 25795132 PMCID: PMC11029723 DOI: 10.1007/s00262-015-1679-3] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2014] [Accepted: 03/04/2015] [Indexed: 01/30/2023]
Abstract
BACKGROUND While surgical resection of pancreatic adenocarcinoma provides the only chance of cure, long-term survival remains poor. Immunotherapy may improve outcomes, especially as adjuvant to local therapies. Gene-mediated cytotoxic immunotherapy (GMCI) generates a systemic anti-tumor response through local delivery of an adenoviral vector expressing the HSV-tk gene (aglatimagene besadenovec, AdV-tk) followed by anti-herpetic prodrug. GMCI has demonstrated synergy with standard of care (SOC) in other tumor types. This is the first application in pancreatic cancer. METHODS Four dose levels (3 × 10(10) to 1 × 10(12) vector particles) were evaluated as adjuvant to surgery for resectable disease (Arm A) or to 5-FU chemoradiation for locally advanced disease (Arm B). Each patient received two cycles of AdV-tk + prodrug. RESULTS Twenty-four patients completed therapy, 12 per arm, with no dose-limiting toxicities. All Arm A patients were explored, eight were resected, one was locally advanced and three had distant metastases. CD8(+) T cell infiltration increased an average of 22-fold (range sixfold to 75-fold) compared with baseline (p = 0.0021). PD-L1 expression increased in 5/7 samples analyzed. One node-positive resected patient is alive >66 months without recurrence. Arm B RECIST response rate was 25 % with a median OS of 12 months and 1-year survival of 50 %. Patient-reported quality of life showed no evidence of deterioration. CONCLUSIONS AdV-tk can be safely combined with pancreatic cancer SOC without added toxicity. Response and survival compare favorably to expected outcomes and immune activity increased. These results support further evaluation of GMCI with more modern chemoradiation and surgery as well as PD-1/PD-L1 inhibitors in pancreatic cancer.

Abstract
This article focuses on the management of locally advanced pancreatic cancer, which should be treated as a distinct entity separate from metastatic disease and borderline resectable disease. Although the role, timing, and sequencing of radiation relative to systemic therapy in this disease are controversial, an emerging treatment paradigm involves induction chemotherapy, followed by consolidative chemoradiation in patients who do not progress. In addition, new chemotherapy regimens as well as novel radiosensitizers have shown promise and need to be tested further in the locally advanced setting. Advances in radiotherapy have enabled stereotactic body radiotherapy and should continue to be prospectively evaluated.

Abstract
While gastrointestinal (GI) hemorrhage is common in the general population, few studies have evaluated large numbers of GI hemorrhage patients with pancreatic cancer. The clinical features and potential risk factors of GI hemorrhage with pancreatic cancer was investigated in the present study and the effect of GI hemorrhage on survival rate was examined. Patients enrolled in the present study had pathologically proven pancreatic cancer, and received treatment between August 2006 and 2012. Their medical records were retrospectively reviewed. The data for the present study were obtained from a review of 246 patients with pancreatic cancer (average age, 63.4±10.92 years; 190 male cases, 56 female cases). In addition, 73 cases had stage I-II, 173 had stage III-IV, and only 67 cases (27.2%) were candidates for curative pancreatectomy. Among them, 32 cases (13.0%) were clinically diagnosed with GI hemorrhage. A total of 24 cases were male patients and the other 8 cases were female, the cases of hemorrhage history and alcoholism were 2 and 29 cases, respectively. The major initial clinical symptoms of GI hemorrhage included 18 patients with melena or blood stool (56.25%), 9 with haematemesis (28.13%), 3 with abdominal distention (9.37%) and 2 with stomach ache (6.25%). The independent risk factor for GI hemorrhage was tumor initial stage of IV. A continuous increase in carbohydrate antigen 19-9 (CA19-9) may be a warning of GI hemorrhage, particularly when it is >1,000 U/ml. The most frequent method of hemostasis was combination therapy (n=12, 37.5%). Only 3 cases (9.3%) of these 32 GI hemorrhage patients were blood stanched and only 10 patients (31.2%) received gastroscopy. The time from GI hemorrhage to fatality is extremely short (median 30 days, range from 1 h to 65 days), and the median overall survival time of the patients with GI hemorrhage was 9.0 months (range, 2.0-16.0 months) and was significantly shorter than that of patients without GI hemorrhage [14.5 months (range, 0.5-48.0 months)]. In conclusion, although GI hemorrhage was not common in patients with pancreatic cancer, it is critical. GI hemorrhage was controlled with endoscopic hemostasis. Clinicians should fully assess the risk factors of GI hemorrhage (such as alcohol, smoking, past hemorrhage history, initial stage, tumor location and CA19-9 level at diagnosis of pancreatic cancer) when the pancreatic cancer patients were on admission, particularly for patients of the late stage, preventive measures should be investigated to reduce suffering.

Abstract
No information is currently available regarding pancreatic cancer (PC) pattern of care in Italy. In the present study, a nationwide survey using a questionnaire was performed to enquire the local standards for PC diagnosis and radiotherapy treatment. Fifty-seven percent of 140 Italian centres completed questionnaire. The main causes of no radiotherapy indication were poor general condition (45%) and lack of guidelines (25%). Physicians (38%) employed neoadjuvant therapy in locally advanced PC patients, while in other centres (62%) adjuvant chemoradiation was administered. Adjuvant gemcitabine-based chemotherapy was selected as the treatment of choice by 59% of centres. Patients were treated mostly with doses of 50-54.9 Gy on the tumour (or bed) plus lymph nodes. A 3D-CRT technique was used in 81.2% of centres, while IMRT and IGRT were available in 61.2 and 48.7% of cases, respectively. Extensive variation exists with regard to patterns of care for PC in Italy. Nevertheless, cooperative studies emerging from this survey appeared beneficial.

Abstract
PURPOSE We developed (224)Ra-loaded wires, which release by recoil alpha emitting nuclei into solid tumors and cause tumor cell killing. This research examined if the major damage was inflicted by alpha particles emitted from these atoms or by direct gamma and beta emissions from the inserted wires. We also examined the efficacy of this treatment against colon cancer in combination with chemotherapy. MATERIALS AND METHODS Mouse colon carcinomas (CT-26 xenografts), treated by intra-tumoral radioactive wires loaded with (224)Ra atoms were monitored for effects on tumor growth, intratumoral tissue damage and distribution of alpha emitting atoms. The effects were compared with those of (224)Ra-loaded wires coated with poly methyl methacrylate (PMMA), which blocks atom recoil. Similar experiments were performed with radioactive wires combined with systemic 5-FU. RESULTS (224)Ra-loaded wires inhibited tumor growth and formed necrotic areas inside the tumor. PMMA coated wires did not inhibit tumor growth, and caused minor intratumoral damage. Autoradiography images of tumors treated with (224)Ra-loaded wires revealed a spread of alpha emitters over several mm, whereas PMMA-coated wires showed no such spread. Injection of 5-FU with (224)Ra-loaded wires augmented tumor growth retardation and cure. CONCLUSIONS (224)Ra-loaded wires ablate solid tumors by the release of alpha-particle emitting atoms inside the tissue, an effect that can be enhanced by combining this method with chemotherapy.

Abstract
Treatment of pancreatic cancer is increasingly multimodal, with patients receiving chemotherapy, radiation, and surgical extirpation in hope of long-term cure. There is ongoing debate over the timing, sequence, and necessity of these treatments as they pertain to the spectrum of local-regional disease. Current guidelines support a neoadjuvant strategy in patients with locally advanced and borderline resectable disease. Although there is currently no high-level evidence to recommend neoadjuvant therapy for all patients, there are data to suggest that wider application of neoadjuvant therapy may be beneficial. Random-assignment prospective trials are ongoing. In this review we examine the literature addressing a neoadjuvant approach to potentially resectable, borderline resectable, and locally advanced pancreatic cancer and highlight the outcomes of preoperative emergence of latent metastatic disease, attempted resection rates, margin negative resection rates, and pathologic response to treatment.

Abstract
Pancreatic adenocarcinoma (PCA) is associated with high rates of cancer-related morbidity and mortality. Yet despite modern treatment advances, the only curative therapy remains surgical resection. The adjuvant therapeutic standard of care for PCA in the United States includes both chemotherapy and chemoradiation; however, an optimal regimen has not been established. For patients with resectable and borderline resectable PCA, recent investigation has focused efforts on evaluating the feasibility and efficacy of neoadjuvant therapy. Neoadjuvant therapy allows for early initiation of systemic therapy and identification of patients who harbor micrometastatic disease, thus sparing patients the potential morbidities associated with unnecessary radiation or surgery. This article critically reviews the data supporting or refuting the role of radiation therapy in the neoadjuvant and adjuvant settings of PCA management, with a particular focus on determining which patients may be more likely to benefit from radiation therapy.

Abstract
Pancreatic ductal adenocarcinoma is a highly lethal cancer that is rarely curable at the time of presentation. Unfortunately, most patients are diagnosed with either metastatic or locally advanced disease, which is not amenable to surgery owing to the high likelihood of incomplete resection. Given the generally poor prognosis with propensity for metastatic failure greater than that for local failure, treatment options are variable, and include chemotherapy, radiotherapy, targeted therapies, and combinations thereof. This review summarizes the current evidence for definitive management of locally advanced pancreatic adenocarcinoma, as well as the role of palliative therapies. Future directions, including the development of predictive biomarkers and novel systemic agents, are also discussed.

FOLFIRINOX for locally advanced pancreatic adenocarcinoma: results of an AGEO multicenter prospective observational cohort. Ann Surg Oncol 2014; 22:295-301. [PMID: 25037971 DOI: 10.1245/s10434-014-3898-9] [Citation(s) in RCA: 125] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2014] [Indexed: 02/06/2023]
Abstract
BACKGROUND First-line treatment with FOLFIRINOX significantly increases overall survival (OS) in patients with metastatic pancreatic adenocarcinoma (PA) compared with gemcitabine. The aim of this observational cohort was to evaluate the tolerability and efficacy of this regimen in unresectable locally advanced PA (LAPA). PATIENTS AND METHODS From February 2010 to February 2012, all consecutive patients from 11 French centers treated by FOLFIRINOX for a histologically proven LAPA were prospectively enrolled. Unresectability was defined independently by each center's multidisciplinary staff at diagnosis. Absence of metastatic disease was confirmed by chest-abdomen-pelvis computed tomography scan. FOLFIRINOX was delivered every 2 weeks as previously reported until progressive disease, major toxicity, or consolidation treatment by radiotherapy and/or surgery. RESULTS Seventy-seven patients were enrolled. They received a median number of five cycles (1-30). Grade 3-4 toxicities were neutropenia (11 %), nausea (9 %), diarrhea (6 %), fatigue (6 %), and anemia (1 %). Grade 2-3 sensory neuropathy occurred in 25 % of patients. No toxic death was reported and only 6 % of patients had to stop treatment because of toxicity. Disease control rate was 84 with 28 % of objective response (Response Evaluation Criteria in Solid Tumors). Seventy-five percent of patients received a consolidation therapy: 70 % had radiotherapy and 36 % underwent a surgical resection, with a curative intent. Within the whole cohort, 1-year OS rate was 77 % (95 % CI 65-86) and 1-year progression-free survival rate was 59 % (95 % CI 46-70). CONCLUSION First-line FOLFIRINOX for LAPA seems to be effective and have a manageable toxicity profile. These promising results will have to be confirmed in a phase III randomized trial.

Abstract
Purpose Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. Materials and Methods Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. Results With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). Conclusion Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

Phase I dose escalation study of capecitabine and erlotinib concurrent with radiation in locally advanced pancreatic cancer. Cancer Chemother Pharmacol 2014; 74:205-10. [PMID: 24908435 DOI: 10.1007/s00280-014-2488-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2014] [Accepted: 05/13/2014] [Indexed: 12/13/2022]
Abstract
PURPOSE Pancreatic cancer is one of the leading causes of cancer-related deaths worldwide. The median survival of locally advanced nonoperable disease is approximately 9 months. 5-FU-based chemoradiotherapy has been the standard treatment. However, the survival benefit of this approach is modest. To improve the efficacy of 5-FU-based chemoradiation therapy, we evaluated the safety and feasibility of the combination of capecitabine and erlotinib with radiotherapy in this group of patients. EXPERIMENTAL DESIGN A traditional "3 + 3" dose escalation design was adopted in the study. A total of four dose levels were designed. For safety purpose, a minus I dose level (-I) was also planned. The -I level consisted of capecitabine 600 mg/m² and erlotinib 50 mg daily, and the remaining four dose levels were as follows: level I: capecitabine 600 mg/m² bid (twice daily); level II: 700 mg/m² bid; level III: 825 mg/m² bid; and level IV: 925 mg/m² bid. Erlotinib was administered at 100 mg daily at all dose levels. Erlotinib and capceitabine were given continuously Monday through Friday concurrent with radiotherapy (50.4 Gy in 28 fractions). RESULTS A total of 18 patients were consented. Fifteen patients were enrolled and completed therapy. No dose-limiting toxicity was observed. The most frequent side effects were lymphopenia, nausea, vomiting, diarrhea, electrolyte imbalances, and skin rashes. The majority of the toxicities were grade 1 and 2. No objective response was observed. The median progression-free survival was 0.59 years (95 % CI 0.31-1.1), and the median overall survival was 1.1 years (95 % CI 0.62-1.59). CONCLUSIONS The combination of capecitabine and erlotinib with radiotherapy in locally advanced pancreatic cancer is well tolerated and feasible at the dose level of capecitabine 925 mg/m² bid and erlotinib 100 mg daily.

BMC Cancer 2014; 14:411.

Abstract
BACKGROUND Median OS after surgery in curative intent for non-metastasized pancreas cancer ranges under study conditions from 17.9 months to 23.6 months. Tumor recurrence occurs locally, at distant sites (liver, peritoneum, lungs), or both. Observational and autopsy series report local recurrence rates of up to 87% even after potentially "curative" R0 resection. To achieve better local control, neoadjuvant CRT has been suggested for preoperative tumour downsizing, to elevate the likelihood of curative, margin-negative R0 resection and to increase the OS rate. However, controlled, randomized trials addressing the impact of neoadjuvant CRT survival do not exist. METHODS/DESIGN The underlying hypothesis of this randomized, two-armed, open-label, multicenter, phase III trial is that neoadjuvant CRT increases the three-year overall survival by 12% compared to patients undergoing upfront surgery for resectable pancreatic cancer. A rigorous, standardized technique of histopathologically handling Whipple specimens will be applied at all participating centers. Overall, 410 patients (n=205 in each study arm) will be enrolled in the trial, taking into regard an expected drop out rate of 7% and allocated either to receive neoadjuvant CRT prior to surgery or to undergo surgery alone. Circumferential resection margin status, i.e. R0 and R1 rates, respectively, surgical resectability rate, local and distant disease-free and global survival, and first site of tumor recurrence constitute further essential endpoints of the trial. DISCUSSION For the first time, the NEOPA study investigates the impact of neoadjuvant CRT on survival of resectable pancreas head cancer in a prospectively randomized manner. The results of the study have the potential to change substantially the treatment regimen of pancreas cancer. TRIAL REGISTRATION Clinical Trial gov: NCT01900327, DRKS00003893, ISRCTN82191749.

Abstract
AIMS To determine the efficacy of induction gemcitabine followed by biweekly gemcitabine concurrent with radiotherapy for locally advanced pancreatic cancer. MATERIALS AND METHODS Between March 2001 and August 2009, 90 patients with unresectable (78) or resected (12) pancreatic cancer were treated with a standard treatment policy of induction gemcitabine (seven doses of weekly gemcitabine at 1000 mg/m(2)) followed by concurrent radiotherapy (52.5 Gy) and biweekly gemcitabine (40 mg/m(2)). RESULTS After induction gemcitabine, 17.8% of patients did not proceed to chemoradiotherapy, due to either disease progression, performance status deterioration or gemcitabine toxicity. Of the patients who received chemoradiotherapy, 68.9% completed the course of 52.5 Gy, whereas 79.7% received more than 45 Gy. Chemoradiotherapy was stopped early due to treatment toxicity in 22.9% of patients. On intention to treat analysis, the median overall survival was 12.7 months in the locally advanced group and 18.2 months in the resected group. On multivariate analysis for the unresectable patients, a larger gross tumour volume was a significant poor prognostic factor for overall survival and local progression-free survival. CONCLUSION This large series confirms, in a standard practice setting, similar efficacy and tolerability of treatment as previously reported in our phase I-II study. The benefit to patients with a gross tumour volume >48 cm(3) may be limited.

Phase II Trial of Cetuximab and Conformal Radiotherapy Only in Locally Advanced Pancreatic Cancer with Concurrent Tissue Sampling Feasibility Study. Transl Oncol 2014; 7:55-64.

Abstract
BACKGROUND Preclinical data have indicated the anti-epidermal growth factor receptor (EGFR) agent cetuximab (Erbitux) as a radiosensitizer in pancreatic cancer, but this has not been specifically addressed in a clinical study. We report the results of an original study initiated in 2007, where cetuximab was tested with radiotherapy (RT) alone in locally advanced pancreatic cancer in a phase II trial (PACER). METHODS Patients (n = 21) received cetuximab loading dose (400 mg/m(2)) and weekly dose (250 mg/m(2)) during RT (50.4 Gy in 28 fractions). Toxicity and disease response end point data were prospectively assessed. A feasibility study of on-trial patient blood and skin sampling was incorporated. RESULTS Treatment was well tolerated, and toxicity was low; most patients (71%) experienced acute toxicities of grade 2 or less. Six months posttreatment, stable local disease was achieved in 90% of evaluable patients, but only 33% were free from metastatic progression. Median overall survival was 7.5 months, and actuarial survival was 33% at 1 year and 11% at 3 years, reflecting swift metastatic progression in some patients but good long-term control of localized disease in others. High-grade acneiform rash (P = .0027), posttreatment stable disease (P = .0059), and pretreatment cancer antigen 19.9 (CA19.9) level (P = .0042) associated with extended survival. Patient skin and blood samples yielded sufficient RNA and good quality protein, respectively. CONCLUSIONS The results indicate that cetuximab inhibits EGFR-mediated radioresistance to achieve excellent local control with minimal toxicity but does not sufficiently control metastatic progression in all patients. Translational studies of patient tissue samples may yield molecular information that may enable individual treatment response prediction.

Abstract
BACKGROUND & AIMS Tumor resistance to radiation is a challenge in the treatment of patients with pancreatic cancer. Improving our understanding of the mechanisms of radioresistance could lead to strategies to increase patients' response to therapy. We investigated the roles of microRNAs (miRNAs) involved in radioresistance of pancreatic cancer cells. METHODS We established radioresistant pancreatic cancer cell lines and used array analysis to compare levels of different miRNAs between radioresistant cell lines and the parental cell lines from which they were derived. We transfected pancreatic cancer cells with miRNA mimics or inhibitors and evaluated their effects on cell radiosensitivity using a clonogenic survival assay. The effects of miRNA on autophagy were determined by transmission electron microscopy and immunoblot analysis. We used a luciferase reporter assay to identify messenger RNA targets of specific miRNAs. RESULTS Radioresistant pancreatic cancer cells had reduced levels of the miRNA miR-23b and increased autophagy compared with cells that were not radioresistant. Overexpression of miR-23b inhibited radiation-induced autophagy, whereas an inhibitor of miR-23b promoted autophagy in pancreatic cancer cells. Overexpression of miR-23b sensitized pancreatic cancer cells to radiation. The target of miR-23b, ATG12, was overexpressed in radioresistant cells; levels of ATG12 protein correlated with the occurrence of autophagy. Expression of miR-23b blocked radiation-induced autophagy and sensitized pancreatic cancer cells to radiation. We observed an inverse correlation between the level of miR-23b and autophagy in human pancreatic cancer tissue samples. CONCLUSIONS In pancreatic cancer cells, reduced levels of the miRNA miR-23b increase levels of ATG12 and autophagy to promote radioresistance. miR-23b might be used to increase the sensitivity of pancreatic cancer cells to radiation therapy.

Comparison of capecitabine and 5-fluorouracil in chemoradiotherapy for locally advanced pancreatic cancer. Radiat Oncol 2013; 8:160. [PMID: 23822606 PMCID: PMC3702484 DOI: 10.1186/1748-717x-8-160] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2013] [Accepted: 06/28/2013] [Indexed: 12/18/2022] Open
Abstract
Background Although capecitabine has theoretical advantages in the pharmacokinetics, such as higher intratumoral and lower systemic concentration, relative to bolus 5-fluorouracil (5-FU), outcomes of chemoradiotherapy (CRT) with capecitabine or bolus 5-FU have not been directly compared in patients with locally advanced pancreatic cancer. Therefore, we retrospectively compared the outcomes, including toxicity, tumor response, and overall survival, of oral capecitabine plus radiotherapy (RT) with bolus 5-FU plus RT, in patients with locally advanced pancreatic cancer. Methods Between August 2006 and January 2012, 98 patients with locally advanced pancreatic cancer received CRT, with 52 receiving concurrent oral capecitabine and 46 receiving bolus injection of 5-FU. Primary tumor and overall response after CRT were evaluated radiologically, and toxicity, tumor response, and overall survival (OS) were compared in the two groups. Results Baseline clinical parameters of the two groups were similar. The rates of ≥ Grade 3 hematologic (0% vs. 8.7%, p = 0.045) and non-hematologic (0% vs. 8.7%, p = 0.045) toxicities were significantly lower in the capecitabine group than in the 5-FU group. Primary tumor (30.7% vs. 28.2%, p = 0.658) and overall (13.7% vs. 15.2%, p = 0.273) response rates and median OS time (12.5 months vs. 11.6 months, p = 0.655) were similar in the two groups. Conclusions Capecitabine plus RT may be a safe and feasible regimen for patients with locally advanced pancreatic cancer, with similar efficacy and low rates of toxicities compared with bolus 5-FU plus RT.

Abstract
Aims and background The aim of the study was to analyze the dose to be administered with two-dimensional involved-field palliative radiotherapy in advanced pancreatic carcinoma with respect to current dose-volume constraints (QUANTEC). Methods and study design The following standard regimens were evaluated: 30 Gy at 3 Gy/fraction (regimen A), 36 Gy at 2.4 Gy/fraction (regimen B), 45 Gy at 1.8 Gy/fraction (regimen C), and 50 Gy at 2 Gy/fraction (regimen D). The following constraints were considered: spinal cord Dmax <50 Gy, duodenum Dmax <55 Gy, liver Dmean <30 Gy, kidneys Dmean <15 Gy. For dose/fraction different from 1.8–2 Gy, the correction of constraints using a value of alpha/beta = 3 for late effects was considered. The calculation of dose/volume constraints was repeated for three different radiation beams: cobalt unit, 6 MV photons, and 15 MV photons. Standard field sizes were used and adapted according to the different beam types, using the parameters of our previous study. Respect of dose-volume constraints was assessed for each type of beam and treatment (dose per fractionation) in all patients. Treatments were considered acceptable in case of: 1) respect of the constraints for spinal cord and duodenum in all patients; 2) respect in >10/15 patients of constraints for kidneys and liver. Therefore, minor violations (<10%) of the constraints for these organs were accepted (in less than 5/15 patients), in consideration of the palliative aim of treatment. Results In regimen A (30 Gy, 3 Gy/fraction), evaluated constraints were respected in all patients, regardless of the type of energy. In regimen B (36 Gy, 2.4 Gy/fraction), constraints were met in all patients undergoing irradiation with 6 and 15 MV photons. However, using the cobalt unit, kidney constraint was respected only in 5 of 15 patients. In regimens C and D (45 Gy, 1.8 Gy/fraction and 50 Gy, 2 Gy/fraction, respectively), the constraint for the kidney was respected only in 2–5 patients, depending on the energy used. Furthermore, using 50 Gy, the spinal cord constraint was not respected in 2–3 patients, depending on the beam used. Therefore, only the following treatments were considered acceptable: 1) 30 Gy, 3 Gy/fraction, regardless of the energy used; 2) 36 Gy, 2.4 Gy/fraction, only for treatments performed with linear accelerator (6–15 MV). Conclusions The clinical benefits of radiotherapy in pancreatic tumors should not be withheld from patients treated in centers only with two-dimensional technology. Prospective trials, particularly in developing countries, would be useful to evaluate the efficacy in this setting of involved-field two-dimensional treatments using the dose and fractionation defined in this analysis.

Abstract
Advanced pancreatic adenocarcinoma historically has a poor prognosis and the mortality rate has remained unchanged for over a decade. Common treatment options for patients with advanced pancreatic cancer include chemoradiation and/or chemotherapy. Single-agent gemcitabine has been considered the standard of care since 1997. Recently published findings indicate that the oxaliplatin, irinotecan, fluorouracil and leucovorin (FOLFIRINOX) treatment regimen significantly improves overall survival compared with gemcitabine. Research has shifted to focus on understanding the causes the resistance of pancreatic cancer to chemotherapy and potential methods to overcome it. This review will focus on the current treatment options, the evolution of targeted therapy, novel agents on the horizon and potential options to ameliorate chemoresistance.

Abstract
BACKGROUND In the UK, chemotherapy is the standard treatment for inoperable, locally advanced, non-metastatic pancreatic cancer. Chemoradiotherapy is also an acceptable treatment option, for which gemcitabine, fluorouracil, or capecitabine can be used as concurrent chemotherapy agents. We aimed to assess the activity, safety, and feasibility of both gemcitabine-based and capecitabine-based chemoradiotherapy after induction chemotherapy for patients with locally advanced pancreatic cancer. METHODS In this open-label, randomised, two-arm, phase 2 trial, patients aged 18 years or older with histologically proven, locally advanced pancreatic cancer (with a tumour diameter of 7 cm or less) were recruited from 28 UK centres between Dec 24, 2009 and Oct 25, 2011. After 12 weeks of induction gemcitabine and capecitabine chemotherapy (three cycles of gemcitabine [1000 mg/m(2) on days 1, 8, 15 of a 28-day cycle] and capecitabine [830 mg/m(2) twice daily on days 1-21 of a 28-day cycle]), patients with stable or responding disease, tumour diameter of 6 cm or less, and WHO performance status 0-1 were randomly assigned to receive a further cycle of gemcitabine and capecitabine chemotherapy followed by either gemcitabine (300 mg/m(2) once per week) or capecitabine (830 mg/m(2) twice daily, Monday to Friday only), both in combination with radiation (50·4 Gy in 28 fractions). Randomisation (1:1) was done via a central computerised system and used stratified minimisation. The primary endpoint was 9-month progression-free survival, analysed by intention to treat including only those patients with valid CT assessments. This trial is registered with ISRCTN, number 96169987. FINDINGS 114 patients were registered and 74 were randomly allocated (38 to the gemcitabine group and 36 to the capecitabine group). After 9 months, 22 of 35 assessable patients (62·9%, 80% CI 50·6-73·9) in the capecitabine group and 18 of 35 assessable patients (51·4%, 39·4-63·4) in the gemcitabine group had not progressed. Median overall survival was 15·2 months (95% CI 13·9-19·2) in the capecitabine group and 13·4 months (95% CI 11·0-15·7) in the gemcitabine group (adjusted hazard ratio [HR] 0·39, 95% CI 0·18-0·81; p=0·012). 12-month overall survival was 79·2% (95% CI 61·1-89·5) in the capecitabine group and 64·2 (95% CI 46·4-77·5) in the gemcitabine group. Median progression-free survival was 12·0 months (95% CI 10·2-14·6) in the capecitabine group and 10·4 months (95% CI 8·9-12·5) in the gemcitabine group (adjusted HR 0·60, 95% CI 0·32-1·12; p=0·11). Eight patients in the capecitabine group had an objective response at 26 weeks, as did seven in the gemcitabine group. More patients in the gemcitabine group than in the capecitabine group had grade 3-4 haematological toxic effects (seven [18%] vs none, p=0·008) and non-haematological toxic effects (ten [26%] vs four [12%], p=0·12) during chemoradiation treatment; the most frequent events were leucopenia, neutropenia, and fatigue. Two patients in the capecitabine group progressed during the fourth cycle of induction chemotherapy. Of the 34 patients in the capecitabine group who received chemoradiotherapy, 25 (74%) received the full protocol dose of radiotherapy, compared with 26 (68%) of 38 patients in the gemcitabine group. Quality-of-life scores were not significantly different between the treatment groups. INTERPRETATION Our results suggest that a capecitabine-based regimen might be preferable to a gemcitabine-based regimen in the context of consolidation chemoradiotherapy after a course of induction chemotherapy for locally advanced pancreatic cancer. However, these findings should be interpreted with caution because the difference in the primary endpoint was non-significant and the number of patients in the trial was small.

Abstract
PURPOSE Improving local control is critical to improving survival and quality of life for patients with locally advanced unresectable pancreatic cancer (LAPC). However, previous attempts at radiation dose escalation have been limited by duodenal toxicity. In order to guide future studies, we analyzed the clinical and dosimetric factors associated with duodenal toxicity in patients undergoing fractionated chemoradiation for LAPC. METHODS AND MATERIALS Medical records and treatment plans of 106 patients with LAPC who were treated with chemoradiation between July 2005 and June 2010 at our institution were reviewed. All patients received neoadjuvant and concurrent chemotherapy. Seventy-eight patients were treated with conventional radiation to 50.4 Gy in 28 fractions; 28 patients received dose-escalated radiation therapy (range, 57.5-75.4 Gy in 28-39 fractions). Treatment-related toxicity was graded according to Common Terminology Criteria for Adverse Events, version 4.0. Univariate and multivariate analyses were performed to assess prognostic influence of clinical, pathologic, and treatment-related factors by using Kaplan-Meier and Cox regression methods. RESULTS Twenty patients had treatment-related duodenal toxicity events, such as duodenal inflammation, ulceration, and bleeding. Four patients had grade 1 events, 8 had grade 2, 6 had grade 3, 1 had grade 4, and 1 had grade 5. On univariate analysis, a toxicity grade ≥2 was associated with tumor location, low platelet count, an absolute volume (cm(3)) receiving a dose of at least 55 Gy (V(55 Gy) > 1 cm(3)), and a maximum point dose >60 Gy. Of these factors, only V(55 Gy) ≥1 cm(3) was associated with duodenal toxicity on multivariate analysis (hazard ratio, 6.7; range, 2.0-18.8; P=.002). CONCLUSIONS This study demonstrates that a duodenal V(55 Gy) >1 cm(3) is an important dosimetric predictor of grade 2 or greater duodenal toxicity and establishes it as a dosimetric constraint when treating patients with unresectable pancreatic cancer with concurrent chemoradiation.

Abstract
Background/Aims While chemoradiotherapy (CRT) is considered to be a reasonable treatment for locally advanced pancreatic cancer (LAPC), there is little information about the associated risk of gastrointestinal (GI) hemorrhage. We investigated the clinical features of GI toxicity after CRT in patients with LAPC and examined the effect of GI hemorrhage on survival. Methods Patients enrolled in this study had received CRT for pathologically proven LAPC. Their medical records were retrospectively reviewed. Results A total of 156 patients with LAPC (median age, 65 years; range, 39 to 90 years) who received treatment between August 2005 and March 2009 were included in this study. The most common GI toxicities were ulcer formation (25.6%) and hemorrhage (25.6%), and the most common grade 3 to grade 5 GI toxicity was hemorrhage (65%). The origins of GI hemorrhage were gastric ulcer (37.5%), duodenal ulcer (37.5%), and radiation gastritis (15.0%). The independent risk factor for GI hemorrhage was tumor location in the pancreatic body. The median overall survival of the patients with a GI hemorrhage was 13.8 months (range, 2.8 to 50.8 months) and was not significantly different from that of patients without GI hemorrhage. Conclusions GI hemorrhage was common in patients with LAPC after CRT. Although GI hemorrhage was controlled with endoscopic hemostasis, preventive measures should be investigated to reduce needless suffering.

Abstract
PURPOSE We retrospectively analyzed the results of patients with locally advanced unresectable pancreatic cancer (LAPC) treated with either chemoradiation (CRT) or chemotherapy alone over the past decade. METHODS AND MATERIALS Between December 1998 and October 2009, 116 patients with LAPC were treated at our institution. Eighty-four patients received concurrent chemoradiation [RT (+) group], primarily 5-flourouracil based (70%). Thirty-two patients received chemotherapy alone [RT (-) group], the majority gemcitabine based (78%). Progression-free survival (PFS) and overall survival (OS) were calculated from date of diagnosis to date of first recurrence and to date of death or last follow-up, respectively. Univariate statistical analysis was used to determine significant prognostic factors for overall survival. RESULTS Median patient age was 67 years. Sixty patients were female (52%). Median follow-up was 11 months (range, 1.6-59.4 months). The RT (+) group received a median radiation dose of 50.4 Gy, was more likely to present with ECOG 0-1 performance status, and experienced less grade 3-4 toxicity. PFS was 10.9 versus 9.1 months (P=0.748) and median survival was 12.5 versus 9.1 months (P=0.998) for the RT (+) and RT (-) groups respectively (P=0.748). On univariate analysis, patients who experienced grade 3-4 toxicity had worse overall survival than those who did not (P=0.02). CONCLUSIONS Optimal management for LAPC continues to evolve. Patients who developed treatment-related grade 3-4 toxicity have a poorer prognosis. Survival rates were not statistically significant between chemotherapy and chemoradiotherapy groups.

Abstract
Systemic chemotherapy for advanced pancreatic cancer is commonly used in practice; however, the optimal strategy for both neoadjuvant and adjuvant therapy in this disease remains controversial. A particular challenge remains in patients who are considered to be locally advanced and either unresectable or borderline resectable. Offering optimal neoadjuvant therapy to this group of patients may give them the opportunity to have a curative surgical approach. This article will discuss the potential role of neoadjuvant therapy in borderline, potentially resectable pancreatic cancer. It will also discuss areas of interest in potential targets as the biology of pancreatic adenocarcinoma is further explored.

Abstract
INTRODUCTION Of all the carcinomas, pancreatic carcinoma (PC) has the highest mortality rate, with a 1- and 5-year survival rate of 25% and less than 5% respectively. This is regardless of the stage at diagnosis. AREAS COVERED In this review relevant literature assessing the evidence regarding preoperative and adjuvant chemoradiotherapy (CRT) is discussed. Furthermore, new therapeutic approaches are summarized, while the future direction regarding the multimodality approach to PC is also discussed. EXPERT OPINION The role of combined-modality therapy for PC is continuously evolving. There have been several recent developments, as well as the completion of major, multi-institutional clinical trials. One of the challenges for the busy clinician is to appreciate the variation in staging, surgical expertise, and application of either definitive CRT or neo-adjuvant CRT for local and/or borderline disease.

Abstract
PURPOSE To identify the dosimetric parameters associated with gastrointestinal (GI) toxicity in patients with locally advanced pancreatic cancer (LAPC) treated with gemcitabine-based chemoradiotherapy. METHODS AND MATERIALS The data from 40 patients were analyzed retrospectively. Chemoradiotherapy consisted of conventional fractionated three-dimensional radiotherapy and weekly gemcitabine. Treatment-related acute GI toxicity and upper GI bleeding (UGB) were graded according to the Common Toxicity Criteria Adverse Events, version 4.0. The dosimetric parameters (mean dose, maximal absolute dose which covers 2 cm(3) of the organ, and absolute volume receiving 10-50 Gy [V(10-50)]) of the stomach, duodenum, small intestine, and a composite structure of the stomach and duodenum (StoDuo) were obtained. The planning target volume was also obtained. Univariate analyses were performed to identify the predictive factors for the risk of grade 2 or greater acute GI toxicity and grade 3 or greater UGB, respectively. RESULTS The median follow-up period was 15.7 months (range, 4-37). The actual incidence of acute GI toxicity was 33%. The estimated incidence of UGB at 1 year was 20%. Regarding acute GI toxicity, a V(50) of ≥ 16 cm(3) of the stomach was the best predictor, and the actual incidence in patients with V(50) <16 cm(3) of the stomach vs. those with V(50) of ≥ 16 cm(3) was 9% vs. 61%, respectively (p = 0.001). Regarding UGB, V(50) of ≥ 33 cm(3) of the StoDuo was the best predictor, and the estimated incidence at 1 year in patients with V(50) <33 cm(3) of the StoDuo vs. those with V(50) ≥ 33 cm(3) was 0% vs. 44%, respectively (p = 0.002). The dosimetric parameters correlated highly with one another. CONCLUSION The irradiated absolute volume of the stomach and duodenum are important for the risk of acute GI toxicity and UGB. These results could be helpful in escalating the radiation doses using novel techniques, such as intensity-modulated radiotherapy, for the treatment of pancreatic cancer.

Abstract
We developed (224)Ra-loaded wires that when inserted into solid tumors, release radioactive atoms that spread in the tumor and irradiate it effectively with alpha particles (diffusing alpha-emitters radiation therapy [DaRT]). In this study, we tested the ability of intratumoral (224)Ra-loaded wires to control the local growth of pancreatic tumors and the enhancement of this effect by chemotherapy. Pancreatic mouse tumors (Panc02) were treated with (224)Ra-loaded wire(s) with or without gemcitabine. The tumor size and survival were monitored, and autoradiography was performed to evaluate the spread of radioactive atoms inside the tumor. Mouse and human pancreatic cancer cells, irradiated in vitro by alpha particles with or without chemotherapy, were evaluated for cell growth inhibition. The insertion of (224)Ra-loaded wires into pancreatic tumors in combination with gemcitabine achieved significant local control and was superior to each treatment alone. A dosimetric analysis showed the spread of radioactive atoms in the tumor around the wires. Alpha particles combined with gemcitabine or 5-FU killed mouse and human cells in vitro better than each treatment alone. DaRT in combination with gemcitabine was proven effective against pancreatic tumors in vivo and in vitro, and the process may be applicable as a palliative treatment for patients with pancreatic cancer.

Abstract
Pancreatic cancer remains associated with an extremely poor prognosis. Surgical resection can be curative, but the majority of patients present with locally advanced or metastatic disease. Treatment for patients with locally advanced disease is controversial. Therapeutic options include systemic therapy alone, concurrent chemoradiation, or induction chemotherapy followed by chemoradiation. We review the evidence to date regarding the treatment of locally advanced pancreatic cancer (LAPC), as well as evolving strategies including the emerging role of targeted therapies. We propose that if radiation is used for patients with LAPC, it should be delivered with concurrent chemotherapy and following a period of induction chemotherapy.
