  • Pathogenesis and treatment strategies of novel coronavirus pneumonia: Reflections on immune checkpoint inhibitor-related adverse events in lung cancer

    In December 2019, an outbreak of pneumonia associated with the coronavirus disease 2019 (COVID-19) occurred in Wuhan, China. The lung imaging finding is like that of the lung cancer immune checkpoint inhibitors (ICI) associated pneumonia. Therefore, we speculated that they may have similar pathogenesis and treatment strategies, which is reviewed in this article in order to provide some reference to timely and effectively reduce the fatality rate of COVID-19.

  • Current status and prospective of neoadjuvant immune checkpoint inhibitors for resectable non-small cell lung cancer

    Surgery remains as the primary definitive therapy for resectable non-small cell lung cancer (NSCLC) currently. However, quite a few NSCLC patients, especially in the later stage, suffered tumor recurrence after resection. Safer and more effective perioperative treatment is urgently needed to reduce the recurrence risk after NSCLC surgery. Immune checkpoint inhibitors can effectively prevent tumor immune evasion and have been shown to be a feasible, safe and effective neoadjuvant therapy for resectable NSCLC. Nevertheless, certain crucial problems, including the final effect on NSCLC recurrence, the selection of beneficial group and optimal treatment protocol are yet unsolved. Fortunately, several phase Ⅲ randomized controlled trials are ongoing to answer these questions and will hopefully provide stronger evidence.

  • Significance of neutrophil-lymphocyte ratio in predicting the prognosis in unresectable hepatocellular carcinoma patients treated with transarterial chemoembolization, lenvatinib, and camrelizumab

    Objective To investigate the prediction of baseline neutrophil-lymphocyte ratio (NLR) on the prognosis of unresectable hepatocellular carcinoma (uHCC) treated with transarterial chemoembolization (TACE) + lenvatinib + camrelizumab. Method The clinical data of 58 patients treated with TACE + lenvatinib + camrelizumab in the Department of Liver Surgery of West China Hospital of Sichuan University from June 2020 to May 2021 were analyzed retrospectively. Results Among the 58 cases included, 7 cases were complete response (CR), 37 cases were partial response (PR), 11 cases were stable disease (SD), and 3 cases were progressive disease (PD). All cases had different degrees of adverse events, including 58 cases of grade 1, 36 cases of grade 2, 35 cases of grade 3, and 1 case of grade 4. The overall response rate (ORR) and disease control rate (DCR) based on modified Response Evaluation Criteria in Solid Tumors (mRECIST) were 75.9% (44/58) and 94.8% (55/58), respectively. The hepatectomy rate was 31.0% (18/58) and the conversion success rate was 37.9% (22/58). Multivariate logistic regression analysis showed that NLR was an independent risk factor for ORR (OR=0.093, P=0.008). All cases were followed up for 16–60 weeks, with a median follow-up of 34 weeks. Overall survival situation (χ2=4.163, P=0.041) and progression free survival situation (χ2=10.626, P=0.001) in the low NLR group were better than those of the high NLR group. Conclusion NLR has clinical significance in predicting the prognosis of uHCC cases underwent TACE + lenvatinib + camrelizumab, which is worthy of further study.

  • Research advances of biomarkers related to the efficacy of immune checkpoint blockade therapy for hepatocellular carcinoma

    ObjectiveTo summarize the biomarkers related to the efficacy of immune checkpoint inhibitors for hepatocellular carcinoma (HCC).MethodReviewed and summarized the literatures on the basic and clinical application of biomarkers related to programmed cell death protein 1/programmed cell death-ligand 1 (PD-1/PD-L1) inhibitors and their combination with targeted therapy.ResultsThe combination of immunotherapy and targeted therapy had brought great hope for the treatment of patients with advanced HCC, but there were still some patients who could not benefit from it. Recent studies had shown that expression of PD-L1 in tumor tissue, tumor mutational burden, tumor-infiltrating lymphocytes, peripheral immune cells, circulating tumor DNA, gut microbiome, and so on, could predict the efficacy of immunotherapy or targeted therapy combined with immunotherapy for HCC.ConclusionsThere is no specific biomarker to predict the efficacy of immunotherapy and its combination regimen for HCC. More prospective studies are needed to confirm the predictive value of these biomarkers and to establish a multi-factor predictive model or immune score to screen patients who may benefit, which is of great significance for precise immunotherapy of HCC.

  • Research status and prospect of immunotherapy for biliary malignancy

    Objective To summarize the research status and prospect of immunotherapy for biliary tract cancer (BTC). Method The literatures about immunotherapy of BTC at home and abroad in recent years were reviewed. Results Surgical resection was still the first choice and only radical treatment for BTC. However, the recurrence rate of BTC was high, and most of the patients were in the middle and late stage with metastasis and lose the opportunity of operation. Patients with local progression, metastasis or recurrence could only receive chemotherapy and other comprehensive treatment, but they could not get satisfactory results. The continuous update of targeted drugs brings new hope for drug therapy of BTC, and immunotherapy had become a new treatment of tumor targeted therapy following radiotherapy and chemotherapy. ConclusionImmunotherapy can be used as an option for the treatment of advanced BTC and its postoperative recurrence and metastasis, and has attracted more and more attention.
