To investigate the effect of borneol on cutaneous toxicity of gilteritinib and to explore possible compounds that can intervene with the cutaneous toxicity.

To investigate the effects and mechanisms of deubiquitinating enzyme Josephin domain containing 2 (JOSD2) on susceptibility of non-small cell lung carcinoma (NSCLC) cells to anti-cancer drugs.

Multiple myeloma (MM) is a common plasma cell malignancy, accounting for the second largest hematological malignancy. Proteasome inhibitors represented by bortezomib (BTZ) have been the main treatment for patients with newly diagnosed and relapsed or refractory myeloma in nearly two decades. Although BTZ has improved the prognosis of MM patients, MM remains incurable in most patients, mainly because MM cells become resistant to BTZ. This review is to better understand the mechanism of MM resistance to BTZ and explore possible new therapeutic strategies.

BCR-ABLT315I mutation is the main mechanism of resistance to the first and second generation tyrosine kinase inhibitor (TKI) for patients with chronic myeloid leukemia (CML). Ponatinib as the third generation TKI has been found that can significantly improve the prognosis of CML patients with T315I mutation. However, the latest report has discovered that the T315I compound mutant is even resistant to ponatinib, which aroused the enthusiasm of research on the mechanism of CML resistance and targeted therapy once again. Previous studies have shown that TKI combined with other targeted drugs is effective to CML patients with drug resistance or relapse due to T315I mutation. The latest research has found that the allosteric inhibitor asciminib combined with TKI therapy is equally effective to CML patients with T315I compound mutant, but the specific mechanism is not yet clarified. This review will focus on the latest research progress of therapy for CML with BCR-ABLT315I mutation, hoping to provide reference for researching new drugs and improve therapy for treating CML with T315I mutation.

To analyze the effects of mangiferin combined with bortezomib on the proliferation, invasion, apoptosis and autophagy of human Burkitt lymphoma Raji cells, as well as the expression of CXC chemokine receptors (CXCRs) family, and explore the molecular mechanism between them to provide scientific basis for basic research and clinical work of Burkitt lymphoma.

Objective: To screen the key genes involved in gefitinib resistance of lung adenocarcinoma PC9/GR cells which harbored 19 exon mutation of epidermal growth factor receptor (EGFR) gene, and discuss the effect and mechanism of downregulation of solute carrier family 7 member 11 (SLC7A11) on the gefitinib resistance of PC9/GR cells. Methods: RNA microarray was conducted to detect the gene expressions in PC9 and PC9/GR cells. The differently expressed genes were screened by using limma package of R language and analyzed by Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis. Western blotting was performed to determine the expression of SLC7A11 protein in PC9 and PC9/GR cells. PC9/GR cells were infected with lentivirus plasmid containing short hairpin RNA (shRNA) targeting SLC7A11 or negative control shRNA (sh-NC), respectively. Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to evaluate the efficacy of shRNA on the expression of SLC7A11 mRNA. Cell counting kit-8 (CCK-8) assay was conducted to determine the suppressing effect of gefitinib on PC9/GR cells. Mito-Tracker Red CMXRos probe and malondialdehyde (MDA) assay kit were used to evaluate gefitinib-induced ferroptosis in PC9/GR cells. Immunohistochemistry (IHC) was conducted to detect the expression of SLC7A11 protein in the tumor tissues of advanced stage lung adenocarcinoma patients harboring 19 exon mutation of EGFR gene. Thirty-six advanced stage lung adenocarcinoma patients who received EGFR-tyrosihe kinase inhibitor(TKI) as first-line treatment in Fourth Hospital of Hebei Medical Unviersity were enrolled. Kaplan-Meier survival curve was drawn to analyze the correlation between SLC7A11 expression and progression-free survival (PFS) of the patients. Results: RNA array demonstrated that 2 888 genes were differently expressed between PC9 and PC9/GR cells. KEGG analysis showed that ferroptosis-related gene was one of the most enriched region of the differently expressed genes between PC9 and PC9/GR cells. These ferroptosis-related gene cohort contained 13 genes, among which SLC7A11 exhibited the most significant difference. Western blotting showed that the expression of SLC7A11 protein in PC9/GR cells was significantly higher than that in PC9 cells (0.76±0.03 vs. 0.19±0.02, P<0.001). The 50% inhibiting concentration (IC(50)) of gefitinib was 35.08 μmol/L and 64.01 μmol/L for sh-SLC7A11 and sh-NC group PC9/GR cells, respectively. PC9/GR cells in sh-SLC7A11 group exhibited significantly lower density of mitochondria fluorescence after gefitinib treatment, compared to the sh-NC group (213.77±26.50 vs. 47.88±4.55, P<0.001). In addition, PC9/GR cells in sh-SLC7A11 group exhibited significantly higher MDA after gefitinib treatment, compared to the sh-NC group [(15.43±1.60) μmol/mg vs. (82.18±7.77) μmol/mg, P<0.001]. The PFS of the patients with low expression of SLC7A11 (n=18) was significantly longer than the patients with high expression of SLC7A11 (n=18, 16.77 months vs. 9.14 months, P<0.001). Conclusion: Downregulation of SLC7A11 could increase the sensitivity of PC9/GR cells to gefitinib by promoting ferroptosis.

Chemotherapy is one of the main options in clinical tumor treatment. Although chemotherapy drugs have a good therapeutic effect, they can also cause a series of adverse reactions, such as neurotoxicity. Chemotherapy-induced neurotoxicity is a dose-limi-ting adverse reaction that significantly affects patients' long-term treatment and quality of life. This article reviewed literature from 2000 to the present on chemotherapy-induced neurotoxicity and found that oxaliplatin was the most frequently used chemotherapy drug. Based on the clinical characteristics of oxaliplatin-induced neurotoxicity, this article summarized the understanding of its pathogenesis from both traditional Chinese medicine(TCM) and western medicine perspectives, discussed the role and mechanism of TCM compounds and monomeric components, and explored the research direction of using cutting-edge biotechnology to reveal the mechanism of oxaliplatin-induced neurotoxicity from a temporal-spatial perspective of intercellular communication and the application prospects of an interdisciplinary model combining TCM pathogenesis, western medicine manifestations, and artificial intelligence in precise intervention decision-making for TCM, aiming to provide research ideas for the prevention and treatment of oxaliplatin-induced neurotoxicity and the development of new drugs.

Cancer treatment-induced thrombocytopenia (CTIT) is a common adverse event during anti-tumor treatment, of which incidence is related to tumor classification, regimens, course of chemotherapy, etc. CTIT may result in a series of events including bleeding, dose intensity reduction, chemotherapy delay, and in severe cases, even the need for platelet transfusion, ultimately affecting the implementation of treatment plan, increasing the cost of treatment, reducing treatment effect and quality of life, and leading to a poor prognosis. The treatment of CTIT should first identify the cause, assess the risk of bleeding, and then adopt treatment strategies according to the cause and severity of CTIT. The main treatments of CTIT include platelet transfusion, application of various types of platelet-producing drugs, and measures to reduce the additional loss of platelets. Among them, platelet-producing drugs mainly refer to platelet-stimulating factors, including recombinant human thrombopoietin (rhTPO), recombinant human interleukin 11(rhIL-11), and thrombopoietin receptor agonists (TPO-RAs). In addition, traditional Chinese medicine also has some assistance in raising platelets. Pharmacological prophylaxis in high-risk patients may help reduce the incidence and severity of CTIT. This consensus aims to support Chinese oncologists in the diagnosis and treatment of CTIT in China, reduce the risk of bleeding and improve the quality of life of patients.

The application of immune checkpoint inhibitors (ICIs) has shown impressive anti-tumor efficacy across multiple malignant tumors, leading to the prolonged survival period of tumor patients. However, immune-related adverse events should not be ignored. Checkpoint inhibitor pneumonitis (CIP) is a pulmonary adverse event that can occur in malignant tumor patients after receiving ICIs treatment. The incidence of CIP has been reported to range from 2.7% to 20.0% in clinical trials and real-world research. Furthermore, some patients might suffer from serious or fatal CIP, and the prognosis of such patients will be poor. Early detection, diagnosis and treatment may improve the prognosis of these patients. The establishment of a whole-process CIP comprehensive surveillance management mode covering the health care system and patients during ICIs treatment might be helpful to improve the early diagnosis and treatment capacity of CIP, which is a key measure to improve the prognosis of these patients.

To explore characteristics of outpatients in a single cardio-oncology clinic, patients visiting cardio-oncology clinic of Fuwai Hospital CAMS&PUMC (Beijing, China) from January 2020 to December 2021 were analyzed retrospectively. In total, 330 patients were included, the median age (Q1, Q3) was 58(46, 66) years, and there were 192 females (58.2%). The purposes for visit included an evaluation and treatment of cardiovascular adverse reactions (n=247, 74.8%), pre-antitumor therapy assessment (n=51, 15.5%), and management of primary or metastatic cardiac tumors (n=32, 9.7%). For patients with cardiovascular adverse reactions, the most common tumor type was breast cancer (n=88, 29.5%), followed by gastrointestinal cancer (n=70, 23.5%), and hematological cancers (n=62, 20.8%). Among them, 236 cases (95.5%) had received antitumor drugs in the past; 38 cases (15.4%) had a history of chest radiotherapy; some cases were complicated with hypertension (n=69, 23.2%) and/or hyperlipidemia (n=69, 23.2%); 42 cases (14.1%) had a history of coronary heart disease; and 16 cases (5.4%) were complicated with atrial fibrillation or flutter. Among 32 patients with cardiac tumors, 11 cases (34.4%) had primary malignant tumors; 6 cases (18.8%) had benign tumors; 2 cases (6.3%) had metastatic tumors; and 13 (40.6%) had unknown pathological types. This study explores the epidemiology of cardio-oncology in China and provides clinical insights for the future development of cardio-oncology. In the future, it is still necessary to study the benefits of cardio-oncology clinics and develop standardized indicators to evaluate their benefits.

Small-molecule compounds with rich sources have diverse structures and activities. The active ingredients in traditional Chinese medicine(TCM) provide new sources for the discovery of new antitumor drugs. Aconitum plants as Chinese medicinal plants have the effects of dispelling wind, removing dampness, warming meridian, and relieving pain. They are mainly used to treat inflammation, pain, rheumatism, and tumors, improve heart function, and dilate blood vessels in clinical practice. Diterpenoid alkaloids are the main active components of Aconitum plants, including C20-, C19-, C18-diterpenoid alkaloids and bis-diterpenoid alkaloids. Stu-dies have demonstrated that diterpenoid alkaloids can effectively treat lung cancer, liver cancer, breast cancer, colon cancer and other cancers. Diterpenoid alkaloids are considered as the most promising natural compounds against cancers. In this review, we summarized the chemical structures and antitumor activities of C20-, C19-, C18-diterpenoid alkaloids and bis-diterpenoid alkaloids extracted from plants of Aconitum, aiming to provide reference for further development of diterpenoid alkaloids from Aconitum as antitumor drugs.

Antibody-drug conjugates (ADCs) are a class of targeted biological agents that link cytotoxic drugs to monoclonal antibodies through linkers. The monoclonal antibody targets tumor cells and transports small-molecule cytotoxic drugs for specific delivery and minimal off-target side effects. September 30, 2022, 14 anti-tumor ADC drugs have been approved for marketing in the world, and four ADCs have been approved in China. With the improvement of the clinical accessibility of ADC drugs, clinicians urgently need to understand the molecular characteristics and mechanisms of ADCs, and clarify the indications for rational use of drugs. Patients' survival mainly depends on the appropriate dose and course of treatment and also on proper management of adverse reactions. In view of this, on the basis of the "Expert Consensus on the Clinical Application of Antibody-drug Conjugates for the Treatment of Malignant Tumors (2020 edition)" , Professional Committee on Clinical Research of Oncology Drugs, Chinese Anti-Cancer Association fully combines the existing clinical research evidence and the feasibility of current ADC drugs in China to update the consensus content. This consensus aims to provide a systematic overview of ADC drugs, so as to provide practical and effective suggestions and references for clinicians to apply and manage ADC drugs more accurately.

Chemotherapy-induced neutropenia (CIN) is a common hematological adverse events and dose-limiting toxicities of chemotherapy. CIN may lead to dose reduction and delay of chemotherapeutic agents, febrile neutropenia and severe infection, which results in increased treatment cost, reduced efficacy of chemotherapy, and even life-threatening morbidities. Assessment of risk of CIN, early detection of FN and infection, and proper prevention and treatment play a crucial role in reducing the occurrence of CIN-related morbidities, improving patient treatment safety and anticancer efficacy. Based on evidence and expert opinion, the expert committee of Chinese Anti-Cancer Association issued "the consensus on diagnosis and treatment of chemotherapy-induced neutropenia in China (2023 edition)", which is an update version of the 2019 edition, aiming to provide reference for the diagnosis and treatment of CIN for Chinese oncologists.

To investigate the correlation between aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphisms and chemotherapy-induced nausea and vomiting (CINV).

Transarterial interventional therapy is one of the most widely used treatment methods in patients with primary hepatocellular carcinoma. With the progress in interventional technology and the use of new drugs, transarterial interventional therapy has achieved favorable results in the treatment of primary hepatocellular carcinoma and has become the first choice non-surgical treatment for advanced liver cancer. However, at present, there are great differences in the drugs used in transarterial interventional treatment and the combined application of other drugs among centers, and there is no uniform consensus or guideline. Based on the latest research data and clinical practice experience, as well as the characteristics of Chinese patients, the Specialist Group of Interventional Drugs, Interventionalists Branch of the Chinese Medical Doctor Association was organized to formulate the Chinese expert consensus on intra-arterial drug and combined drug administration for primary hepatocellular carcinoma. The purpose of this consensus is to explore the efficacy and safety of drugs and drug combinations related to intra-arterial interventional therapy, the use of drugs in special populations, the management of adverse reactions, and adjuvant drugs to provide a reference for clinical practice.

The synergistic effect of drug combinations can solve the problem of acquired resistance to single drug therapy and has great potential for the treatment of complex diseases such as cancer. In this study, to explore the impact of interactions between different drug molecules on the effect of anticancer drugs, we proposed a Transformer-based deep learning prediction model-SMILESynergy. First, the drug text data-simplified molecular input line entry system (SMILES) were used to represent the drug molecules, and drug molecule isomers were generated through SMILES Enumeration for data augmentation. Then, the attention mechanism in the Transformer was used to encode and decode the drug molecules after data augmentation, and finally, a multi-layer perceptron (MLP) was connected to obtain the synergy value of the drugs. Experimental results showed that our model had a mean squared error of 51.34 in regression analysis, an accuracy of 0.97 in classification analysis, and better predictive performance than the DeepSynergy and MulinputSynergy models. SMILESynergy offers improved predictive performance to assist researchers in rapidly screening optimal drug combinations to improve cancer treatment outcomes.
