Researchers in the laboratory have tested tumors from patients with pancreatic cancer and have discovered that they have certain pathways inside the cells that promote growth and survival of the tumor. Because chloroquine (CQ) inhibits formation of neutrophil extracellular traps [13], we sought to determine if chloroquine treatment would reverse the NET mediated platelet activation and aggregation, and release of tissue factor in tumor bearing animals. The receptor for advanced glycation end products (RAGE) enhances autophagy and neutrophil extracellular traps in pancreatic cancer. We previously conducted a phase I/II trial examining preoperative gemcitabine in combination with oral hydroxychloroquine for the treatment of patients with high-risk PDA (UPCI 09-122/NCT01128296; ref. 2017;129(10):1357–67. Br Med J. These studies are designed to fail. J Surg Oncol. Large area scan images were captured with a Nikon A1confocal microscope (NIS Elements 4.4, Tokyo, Japan). While these findings point to extracellular DNA and RAGE promoting NET mediated platelet aggregation, there are many components released from NETs that may also have an impact on hypercoagulability and were not evaluated in the current analysis. Tumor bearing mice had elevated levels of serum tissue factor compared with sham controls (Fig. 3a & b). These findings implicate a role for DNA and RAGE in NET induced platelet aggregation. Hydroxychloroquine (HCQ) is a 4-aminoquinoline agent that has been used for >50 years to prevent or to treat malarial infections and later also to treat autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. 2007;13(10):2870–5. Manage cookies/Do not sell my data we use in the preference centre. Treatment with the autophagy inhibitor chloroquine results in a reversal of hypercoagulability in pancreatic cancer by diminishing NET mediated platelet aggregation and release of circulating tissue factor and improving coagulation index on TEG. All patients signed informed consent prior to participation in these clinical protocols.

Venous thromboembolism was reported from the initiation of treatment through the 90 day postoperative period. Representative images from three individual patients are shown, demonstrating focal areas of elastase and fibrinogen in the tumor, suggesting interactions between neutrophils and thrombosis in the tumor microenvironment. Importantly, PAD4 also citrullinates and inhibits antithrombin [44, 45], suggesting another possible mechanism of hypercoagulability in pancreatic cancer. The 90 day VTE rate for patients treated with 2 cycles of preoperative gemcitabine/abraxane + HCQ was 9.1% (n = 3 of 33) compared to 30% (n = 9 of 30) in patients treated with gemcitabine/abraxane alone (c, p = 0.053).

In both trials, hydroxychloroquine was initiated 48 h before the first dose of chemotherapy and continued until the day before surgery. Recently, neutrophil extracellular traps (NETs), whereby activated neutrophils release their intracellular contents containing DNA, histones, tissue factor, high mobility group box 1 (HMGB1) and other components have been implicated in PDA and in cancer-associated thrombosis. Mean plasma DNA decreased with treatment in the HCQ group, consistent with potential NET inhibition (601 ± 129 vs. 539 ± 114 ng/mL, p < 0.05), but not in the gemcitabine/nab-paclitaxel alone group (588 ± 144 vs. 543 ± 166 ng/mL, p = 0.09). NETs and down-stream signaling pathways represent a novel target for further research on cancer associated thrombosis [15]. Pancreatic tumor specimens from resected patients with pancreatic adenocarcinoma were stained for neutrophil elastase (red) and fibrinogen (white). Abstract Background: The hypercoagulable state associated with pancreatic adenocarcinoma (PDA) results in increased risk of venous thromboembolism, leading to substantial morbidity and mortality. Correlative patient samples and data were included from two clinical trial protocols that were approved by the Institutional Review Board for the University of Pittsburgh (Protocol #10010028 and #13080444).

Martinod K, Demers M, Fuchs TA, Wong SL, Brill A, Gallant M, et al. Arthritis Rheum. Chloroquine treatment led to a significant reduction in serum tissue factor levels in tumor bearing mice with no significant change in sham mice (Fig. 4d). Cycle duration was 4 weeks. Despite various approaches for thromboprophylaxis, both VTE and subsequent treatments for it are significant sources of morbidity and mortality. RAGE KO tumor bearing mice had decreased platelet aggregation compared to WT tumor bearing mice (Fig. 2c). To substantiate the role of NETs in upregulated platelet function, we injected orthotopic tumor into the pancreas of PAD4 KO and syngeneic wild type controls. TEG has been most thoroughly studied in patients during massive bleeding from trauma as a rapidly available test to direct transfusion of blood products, however, it is becoming more frequently utilized to identify hypercoagulability [20]. Nonetheless, these findings support a clinical trial designed specifically to study reduction in VTE by treatment of cancer patients with perioperative HCQ. Knockout mice deficient in the receptor for advanced glycation end products (RAGE−/−, SVEV129 x C57/BL6), a critical inducer of autophagy and NET formation in pancreatic cancer, were also studied and made available by the late Angelika Bierhaus (Heidelberg). The finding suggests that resistance to immunotherapy due to internalisation of MHC-I seen in pancreatic cancer cells could be at work in other cancer types.

Part of Autophagy, a cancer cell survival mechanism whereby damaged organelles, proteins and other intracellular components are recycled, appears to be critical for NET formation in pancreatic cancer [13]. To determine if NETs played a role in this enhanced platelet function, we treated whole blood from C57/Bl6 wild type mice and healthy human volunteers with NET supernatant for 10 min and assessed platelet activation and aggregation. 2011;6(7):e22043. Neutrophil extracellular traps sequester circulating tumor cells and promote metastasis. Additionally, RAGE knockout mice had no differences in platelet aggregation at baseline, but had decreased platelet aggregation in tumor burdened mice compared with wild type. Furthermore, the autophagy inhibitor chloroquine inhibits NET formation [13, 14]. The datasets used and/or analyzed during the current study are available from the corresponding author on reasonable request. 1974;3(5923):94–5. A recently described phenomenon that occurs in activated neutrophils, neutrophil extracellular trap formation or NETs, has been described as a potential contributor to hypercoagulability. Appearance of one or more new lesions is classified as progression of non-target lesions. Wun T, White RH. Next, we treated tumor bearing mice with DNase I and observed a significant reduction in platelet aggregation (Fig. 2b). Oncoimmunology. 2012;3:307.

At the onset of the COVID-19 pandemic, hydroxychloroquine became a hot topic as a possible treatment for the virus.Clinical trials largely found that the drug was not a viable treatment option. All experimental animal procedures were reviewed and approved by the Institutional Animal Care and Use Committee of the University of Pittsburgh (Protocol # 14084123). CR or PR confirmation is required >/= 4 weeks. It is possible that CQ may only serve a beneficial role in reducing hypercoagulability in the cancer burdened state, where NETs are upregulated. Data is reported as the area under the curve (AUC), which incorporates both the slope and amplitude of the aggregation curve. Google ScholarÂ. For target lesions, complete response (CR) is disappearance of all target lesions and partial response (PR) is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. CAS  TEG was performed on 340 μl murine whole blood drawn via submandibular bleed mixed with 1:9 dilution of 3.4% sodium citrate and 10 units/mL heparin using a Haemoscope 5000 analyzer (Haemonetics, Braintree, MA, USA) as previously described [19]. This could explain why prior randomized trials of CQ to decrease VTE in non-malignant orthopedic patients were inconclusive [46, 47]. Hepatobiliary Surg Nutr. All together our findings support additional clinical trials with hydroxychloroquine to examine the ability of NET inhibition to lower the venous thromboembolism rate in patients with pancreatic and other cancer types. Patients were considered to have experienced PD if they demonstrated either clinical deterioration resulting in withdrawal or PD per RECIST 1.0 criteria: At least a 20% increase in the sum of longest diameter (LD) of target lesions taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.
