    Mechanism of ferroptosis and its relationship with tumors
    Cheng Lin, Zhao Mingfeng
    Journal of International Oncology 2018, 45 (10): 619-623. DOI:10.3760/cma.j.issn.1673-422X.2018.10.009

    Ferroptosis is a new type of cell death discovered in recent years. This form of irondependent cell death is morphologically and biochemically distinct from other cell death modalities, including apoptosis and necrosis. This process is accompanied by the depletion of glutathione, a decrease in glutathione peroxidase activity and the accumulation of lipid peroxidation products. Studies have found that ferroptosis can be involved in the occurrence and progression of tumor by activating different regulatory sites in the signaling pathways, which can promote tumor cell death. Therefore, to clarify ferroptosis pathway and its related mechanisms regulating tumor development may provide new ideas for clinical treatment of tumors.

    JIANG Xue, YAN Sen-Xiang, XU Qiu-Yi, et al
    Journal of International Oncology 2013, 40 (8): 584-586.
    Abstract2834 PDF(pc)(660KB)( 1693 Save
    The oligometastasic stage is an intermediate state with mild biological invasion, in which spread may be limited to specific organs and not occour polymetastases. The number of metastatic tumors is limited less than five. Local therapy such as radiotherapy, surgery and radiofrequency ablation for the relapsed sites could thus improve patient’s survival. The expression of miR-200 family characterizes oligometastasis(es). Correct understanding and familiarization with treatment of oligometastasis may change the traditional therapeutic strategy of advanced tumors,and some advanced cancer patients may achieve curable results.

    Chemotherapy and tumor immunogenic cell death
    LUO Cong, TAO Ning
    Journal of International Oncology 2017, 44 (5): 369-372. DOI:10.3760/cma.j.issn.1673422X.2017.05.011
    Abstract2179 PDF(pc)(670KB)( 3020 Save
    Chemotherapy resist is the problem for clinic, and some researches find that chemotherapy with anthracycline and oxaliplatin not only induces the tumor cell apoptosis, but also the cell immunogenic cell death (ICD) by inducing the tumor cell apoptosis and releasing three kinds of signals: exposure of calreticulin on the cell surface to stimulate the dendritic cell (DC) to engulf, and the secretion of adenosine triphosphate to recruit DC to enter into tumor bed, and the release of the high mobility group B1 to promote DC to steadily bind with dying tumor cell to induce specific T cell antitumor immune response. It is with great meaning to promote the chemotherapy protocol by studying the ICD induced by chemotherapy.

    The solute carrier protein 25 family (SLC25) is one of superfamily in solute carrier protein family. The members of SLC25 family function by transporting various solutes across the mitochondrial membrane. Their substrates vary in property, molecular size and mode of transport, and they closely involve in numerous physiological functions. More and more researches indicate that some members of SLC25 family are abnormally expressed in tumors, and some of them play important roles in the occurrence and development of tumors. For example, some members participate in tumorigenesis by regulating cell metabolism, death and proliferation.

    ObjectiveTo observe the clinical efficacy and adverse reactions of apatinib combined with albumin-bound paclitaxel in elderly patients with relapsed and metastatic gastric cancer.MethodsA total of 72 elderly patients with relapsed and metastatic gastric cancer diagnosed in the Department of Oncology, West District of the First Affiliated Hospital of University of Science & Technology of China from June 1, 2017 to June 1, 2019 were chosen. The patients were divided into control group (n=36) and study group (n=36) using random number table method. The control group received only albumin-bound paclitaxel chemotherapy, and the study group continued oral apatinib based on the control group's chemotherapy, every 3 weeks for one chemotherapy cycle, a total of 4 cycles. The short-term efficacy, median overall survival (OS), median progression-free survival (PFS), serum carcinoembryonic antigen (CEA), carbohydrate antigen 199 (CA199), carbohydrate antigen 72-4 (CA72-4) and adverse reactions were compared between the two groups.ResultsThe objective response rate and disease control rate of the study group were 55.56% (20/36) and 77.78% (28/36) respectively, which were higher than those of the control group [30.56% (11/36) and 55.56% (20/36)], and there were statistically significant differences (χ2=4.589,P=0.032;χ2=4.000,P=0.046). After 4 cycles treatment, the serum CEA, CA199 and CA72-4 levels in the study group were (12.5±3.3) μg/L, (35.6±6.7) U/ml, (13.5±2.2) U/ml respectively, which were lower than those in the control group [(22.8±4.1) μg/L, (55.6±7.4) U/ml, (21.7±3.4) U/ml], and there were statistically significant differences (t=7.008,P=0.017;t=9.365,P=0.008;t=8.862,P=0.011). The incidences of gastrointestinal reactions and myelosuppression were 38.89% (14/36) and 44.44% (16/36) in the study group, and 36.11% (13/36) and 41.67% (15/36) in the control group respectively, with no significant differences (χ2=0.059,P=0.808;χ2=0.057,P=0.811). The incidences of hypertension, hand-foot syndrome, oral mucositis and proteinuria in the study group were 27.78% (10/36), 41.67% (15/36), 27.78% (10/36) and 16.67% (6/36) respectively, which were higher than those in the control group [8.33% (3/36), 16.67% (6/36), 5.56% (2/36) and 2.78% (1/36)], and there were statistically significant differences (χ2=4.600,P=0.032;χ2=5.445,P=0.020;χ2=6.400,P=0.011;χ2=3.956,P=0.047), which could be tolerated after symptomatic treatment. The median OS and PFS of the study group were 18.2 months and 16.1 months, which were longer than those of the control group (11.8 months and 8.0 months), and there were statistically significant differences (χ2=6.821,P=0.015;χ2=5.868,P=0.018).ConclusionApatinib combined with albumin-bound paclitaxel is superior to albumin-bound paclitaxel single-agent chemotherapy in elderly patients with relapsed and metastatic gastric cancer, which can prolong the PFS and OS, and the adverse reactions are tolerable.

    Anaplastic thyroid carcinoma (ATC) is very rare and aggressive in humans, and its survival time is most often expressed in weeks or months. For now, there is no standard treatment for longterm survival, even if the multidisciplinary approach could prolong survival in some patients. The development of oncomolecular biology promotes the understanding about the pathogenesis of ATC from genetic level, and then providing a theoretical basis for targeted therapy. Some targeted drugs have been approved for the treatment of refractory advanced differentiated thyroid cancer, in the meantime, the clinical trials of targeted therapy bring new hope for ATC patients.

    Epstein-Barr virus (EBV) positive diffuse large B cell lymphoma (DLBCL) is a rare type of B cell lymphoma associated with chronic EBV infection. The main subtype is activated B cell-like and it's invasive. The response to combined chemotherapy is worse than that of EBV negative patients, and the prognosis is poor. As the researches on pathogenesis and biological characteristics of EBV positive DLBCL deepen, new therapeutic strategies are emerging, such as antiviral therapy, monoclonal antibody, inhibitors of signaling pathway and immunotherapy including cellular immunotherapy and immune checkpoint inhibitor. These new therapeutic strategies can improve the efficacy and reduce the occurrence of adverse reactions.

    At present, immune checkpoint inhibitors (ICIs) are widely used in clinical, and the common adverse reactions include adverse reactions of skin, gastrointestinal tract, endocrine and liver. Adverse reactions to the lungs and heart are relatively rare, but can be fatal. Systemic steroid therapy is the main treatment for immune related adverse events (irAEs). If there is no response to steroid therapy, an immunomodulator may be considered. Understanding the incidence, pathogenesis, common types and treatment strategies of irAEs can provide theoretical basis for the safe application of ICIs in clinical practice.

    Effects and mechanisms of bevacizumab-induced renal impairment
    He Yi, Xu Qunhong, Chen Xueqin, Pan Yuelong, Wang Ming
    Journal of International Oncology 2014, 41 (8): 602-605. DOI:10.3760/cma.j.issn.1673-422X.2014.08.014
    Abstract1719 PDF(pc)(889KB)( 1466 Save
    Bevacizumab has been widely used in tumor targeting therapy, while the most common adverse reaction is renal impairment, manifested as proteinuria. The main mechanisms may include interfering podocytesendothelial vascular endothelial growth factor(VEGF) axis signals, increasing glomerular pressure caused by secondary hypertension, subacute renal thrombotic microangiopathy caused by endothelial damage and so on. Thrombotic microangiopathy is the main renal pathological type, and other rare types include glomerular lesions, renal interstitial disease, and benign renal arteriolar nephrosclerosis. Therefore, urine protein excretion and renal function should be closely monitored during bevacizumab treatment period for timely treatment, dose reduction or even withdrawal if necessary to ensure renal function.

    The majority of patients with malignant tumors have hypercoagulable state, which easily leads to thrombosis, and is closely related with recurrence of tumor metastasis. The formation mechanism of hypercoagulable state is related to tumor, tumor treatment, complications etc. The main diagnostic indicators are the platelet, cruor and fibrinolysis, Pselectin and lysosomal protein, blood rheology. Tumor patients with the high risk of thrombus should use low molecular weight heparin. Thromboembolism should be prevented in bedridden patients with tumor and tumor associated operation. Tumor patients with venous thromboembolism should be given thrombolytic treatment. Tumor patients with hypercoagulable state should be treated by anticoagulant therapy combined with chemotherapy.
