| 1 | Targeted therapy or immunotherapy? Optimal treatment in hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the fifth leading cause of cancer mortality in the United States and the second leading cause of cancer mortality worldwide. Sorafenib is the only food and drug administration(FDA) approved as first line systemic treatment in HCC. Regorafenib and nivolumab are the only FDA approved second line treatment after progression on sorafenib. We will discuss all potential first and second line options in HCC. In addition, we also will explore sequencing treatment options in HCC, and examine biomarkers that can potentially predict benefits from treatments such as immune checkpoint inhibitor. This minireview summarizes potential treatments in HCC based on clinical trials that have been published in manuscript or abstract format from 1994-2018. | Merly Contratto Jennifer Wu | 2018 | World Journal of Gastrointestinal Oncology2018，10，5： | 12 |
| 2 | Immunotherapy in pancreatic cancer:Unleash its potential through novel combinations显示文摘Pancreatic cancer is the third leading cause of cancer mortality in both men and women in the United States,with poor response to current standard of care,short progression-free and overall survival.Immunotherapies that target cytotoxic T lymphocyte antigen-4,programmed cell death protein-1,and programmed death-ligand 1 checkpoints have shown remarkable activities in several cancers such as melanoma,renal cell carcinoma,and nonsmall cell lung cancer due to high numbers of somatic mutations,combined with cytotoxic T-cell responses.However,single checkpoint blockade was ineffective in pancreatic cancer,highlighting the challenges including the poor antigenicity,a dense desmoplastic stroma,and a largely immunosuppressive microenvironment.In this review,we will summarize available clinical results and ongoing efforts of combining immune checkpoint therapies with other treatment modalities such as chemotherapy,radiotherapy,and targeted therapy.These combination therapies hold promise in unleashing the potential of immunotherapy in pancreatic cancer to achieve better and more durable clinical responses by enhancing cytotoxic T-cell responses. | Songchuan Guo Merly Contratto George Miller Lawrence Leichman Jennifer Wu | 2017 | World Journal of Clinical Oncology2017，8，3： | 3 |
| 3 | Evaluation of a locked nucleic acid form of antisense oligo targeting HIF-1α in advanced hepatocellular carcinoma显示文摘BACKGROUND Hypoxia-inducible factor 1α(HIF-1α) is a gene that regulates tumor survival,neovascularization and invasion. Overexpression of HIF-1α correlates with poor prognosis in hepatocellular carcinoma(HCC). RO7070179 is a HIF-1α inhibitor that decreases HIF-1α mRNA and its downstream targets, it could be a potential treatment in HCC.AIM To evaluate safety and preliminary activity of RO7070179 in patients with previously treated HCC, with focus on a patient with prolonged response to RO7070179.METHODS In the preclinical study of RO7070179 in a HCC xenograft model, the mice wereseparated into 4 groups with each group received doses of 0, 3, 10 and 30 mg/kg for total 10 doses. HCC patients who failed at least one line of systemic treatment,received RO7070179 as a weekly infusion, each cycle is 6 wk. We evaluated the safety and HIF-1α mRNA levels of RO7070179.RESULTS Preclinical evaluation of RO7070179 in orthotopic HCC xenograft model showed no significant differences in HCC tumor weight between the 3 and 10 mg/kg groups. However, dose of 10 mg/kg of RO7070179, has shown 76% reduction of the amount of HIF-1α mRNA in HCC tissue. In the phase 1 b study of RO7070179 in previously treated HCC patients, 8 out of 9 were evaluable: 1 achieved PR and1 SD. The patient with PR responded after 2 cycles treatments, which has been maintained for 12 cycles. This patient also showed reduction in perfusion of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI) after 1 cycle of treatment. After 1 cycle of treatment, both patients with PR and SD showed decrease in HIF-1α mRNA at the root of biopsies(each biopsy was divided into 2 specimens, the tip and the root).CONCLUSION RO7070179 can reduce HIF-1α mRNA level in HCC patients with SD or PR. It is well tolerated at 10 mg/kg, with transaminitis as the dose of increased toxicity.This study indicates that RO7070179 might benefit HCC patients, and an early signal for clinical benefit can potentially be predicted through changes in either m RNA level or DCE-MRI within 1 cycle of therapy. | Jennifer Wu Merly Contratto Krishna P Shanbhogue Gulam A Manji Bert H O'Neil Anne Noonan Robert Tudor Ray Lee | 2019 | World Journal of Clinical Oncology2019，10，3： | 2 |
