1.A Cocktail of Natural Compounds Holds Promise for New Immunotherapeutic Potential in Head and Neck Cancer.
Chinese journal of integrative medicine 2024;30(1):42-51
OBJECTIVE:
To obtain detailed understanding on the gene regulation of natural compounds in altering prognosis of head and neck squamous cell carcinomas (HNSC).
METHODS:
Gene expression data of HNSC samples and peripheral blood mononuclear cells (PBMCs) of HNSC patients were collected from Gene Expression Omnibus (GEO). Differential gene expression analysis of GEO datasets were achieved by the GEO2R tool. Common differentially expressed gerres (DEGs) were screened by comparing DEGs of HNSC with those of PBMCs. The combination was further analyzed for regulating pathways and biological processes that were affected.
RESULTS:
Totally 110 DEGs were retrieved and identified to be involved in biological processes related to tumor regulation. Then 102 natural compounds were screened for a combination such that the expression of all 110 commonly DEGs was altered. A combination of salidroside, ginsenoside Rd, oridonin, britanin, and scutellarein was chosen. A multifaceted, multi-dimensional tumor regression was showed by altering autophagy, apoptosis, inhibiting cell proliferation, angiogenesis, metastasis and inflammatory cytokines production.
CONCLUSIONS
This study has helped develop a unique combination of natural compounds that will markedly reduce the propensity of development of drug resistance in tumors and immune evasion by tumors. The result is crucial to developing a combinatorial natural therapeutic cocktail with accentuated immunotherapeutic potential.

Lung cancer has the highest risk of brain metastasis (BM) among all solid carcinomas. The emergence of BM has a significant impact on the selection of oncologic treatment for patients. Immune checkpoint inhibitors (ICIs) are the most promising treatment option for patients without druggable mutations and have been shown to improve survival in patients with non-small cell lung cancer (NSCLC) BM in clinical trials with good safety. Moreover, ICI has shown certain effects in NSCLC BM, and the overall intracranial efficacy is comparable to extracranial efficacy. However, a proportion of patients showed discordant responses in primary and metastatic lesions, suggesting that multiple mechanisms may exist underlying ICI activity in BM. According to studies pertaining to tumor immune microenvironments, ICIs may be capable of provoking immunity in situ . Meanwhile, systematic immune cells activated by ICIs can migrate into the central nervous system and exert antitumor effects. This review summarizes the present evidence for ICI treatment efficacy in NSCLC BM and proposes the possible mechanisms of ICI treatment for NSCLC BMs based on existing evidence.

4.Chinese expert consensus on intra-arterial drug and combined drug administration for primary hepatocellular carcinoma.
Chinese Journal of Internal Medicine 2023;62(7):785-801
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.

Chinese Journal of Lung Cancer 2023;26(4):257-264
BACKGROUND:
Immune-related adverse events (irAEs) are commonly occurred in patients treated with immune checkpoint inhibitors. However, evidence of irAEs derived from the Chinese population is relatively lacking. The aim of this study was to investigate the incidence and outcomes of irAEs in Chinese patients with lung cancer after receiving immune checkpoint inhibitors (ICIs).
METHODS:
Clinical and follow-up data from lung cancer patients who received at least one time of ICIs from January 2018 to September 2021 at Huadong Hospital, Fudan University were included. Statistical descriptions and Kaplan-Meier method were used to analyze the overall incidence of irAEs, as well as the incidence and outcomes of each type of irAEs.
RESULTS:
135 patients were included in the study. 106 patients (78.5%) presented at least one type of irAEs, and the median time to first irAEs onset was 28 d. Most irAEs occurred at early time after treatment, and most irAEs were mild-moderate and reversible. 57 patients (42.2%) died at the study cutoff. The mortality rate of severe irAEs was 12.6% (n=17), and among them 7 patients (41.2%) died of pneumonitis. The median progression-free survival (PFS) and overall survival (OS) time of the total population was 505 d (95%CI: 352-658) and 625 d (95%CI: 491-759), respectively. Patients who presented any irAEs achieved a longer PFS than those who did not (median PFS: 533 d vs 179 d, P=0.037, HR=0.57), while patients who presented skin toxicities achieved a longer OS than patients who did not (median OS: 797 d vs 469 d, P=0.006, HR=0.70).
CONCLUSIONS
In real-world settings, irAEs in lung cancer patients were commonly observed, with pneumonitis as the most common fatal irAEs. In addition, patients who presented any irAEs may tend to achieve a longer PFS.

Lung cancer is one of the most lethal malignancies in the world, with non-small cell lung cancer (NSCLC) accounting for approximately 80%-85% of all pathological types. Approximately 30%-55% of NSCLC patients develop brain metastases. It has been reported that 5%-6% of patients with brain metastases harbor anaplastic lymphoma kinase (ALK) fusion. ALK-positive NSCLC patients have shown significant therapeutic benefits after treatment with ALK inhibitors. Over the past decade, ALK inhibitors have rapidly evolved and now exist in three generations: first-generation drugs such as Crizotinib; second-generation drugs including Alectinib, Brigatinib, Ceritinib, and Ensartinib; and third-generation drugs like Lorlatinib. These drugs have exhibited varying efficacy in treating brain metastases in ALK-positive NSCLC patients. However, the numerous options available for ALK inhibition present a challenge for clinical decision-making. Therefore, this review aims to provide clinical guidance by summarizing the efficacy and safety of ALK inhibitors in treating NSCLC brain metastases.

Immunotherapy has significantly improved clinical outcomes of non-small cell lung cancer (NSCLC), however, along with the popularization of immunotherapy, immune resistance has become an unavoidable problem. Immunotherapy can induce extensive cellular and molecular alterations in the tumor microenvironment. Considering the mechanisms of immune resistance are not yet fully understood and the efficacy of standard chemotherapy regimens is limited, more effective coping strategies based on resistance mechanisms are urgently needed. In this review, we intend to summarize the known mechanisms of immune resistance and feasible strategies, so as to provide a foundation for clinicians to develop more individualized and precise regimens and finally improve patients' prognosis.

Lung squamous cell carcinoma (LSCC) accounts for approximately 30% of non-small cell lung cancer (NSCLC) cases and is the second most common histological type of lung cancer. Anaplastic lymphoma kinase (ALK)-positive NSCLC accounts for only 2%-5% of all NSCLC cases, and is almost exclusively detected in patients with lung adenocarcinoma. Thus, ALK testing is not routinely performed in the LSCC population, and the efficacy of such treatment for ALK-rearranged LSCC remains unknown. Echinoderm microtubule associated protein like 4 (EML4)-ALK (V1) and TP53 co-mutations were identified by next generation sequencing (NGS) in this patient with advanced LSCC. On December 3, 2020, Ensatinib was taken orally and the efficacy was evaluated as partial response (PR). The progression-free survival (PFS) was 19 months. When the disease progressed, the medication was changed to Loratinib. To our knowledge, Enshatinib created the longest PFS of ALK-mutant LSCC patients treated with targeted therapy since literature review. Herein, we described one case treated by Enshatinib involving a patient with both EML4-ALK and TP53 positive LSCC, and the relevant literatures were reviewed for discussing the treatment of this rare disease.

Treating patients with esophageal squamous cell carcinoma (ESCC) is challenging due to the high chemoresistance. Growth differentiation factor 15 (GDF15) is crucial in the development of various types of tumors and negatively related to the prognosis of ESCC patients according to our previous research. In this study, the link between GDF15 and chemotherapy resistance in ESCC was further explored. The relationship between GDF15 and the chemotherapy response was investigated through in vitro and in vivo studies. ESCC patients with high levels of GDF15 expression showed an inferior chemotherapeutic response. GDF15 improved the tolerance of ESCC cell lines to low-dose cisplatin by regulating AKT phosphorylation via TGFBR2. Through an in vivo study, we further validated that the anti-GDF15 antibody improved the tumor inhibition effect of cisplatin. Metabolomics showed that GDF15 could alter cellular metabolism and enhance the expression of UGT1A. AKT and TGFBR2 inhibition resulted in the reversal of the GDF15-induced expression of UGT1A, indicating that TGFBR2-AKT pathway-dependent metabolic pathways were involved in the resistance of ESCC cells to cisplatin. The present investigation suggests that a high level of GDF15 expression leads to ESCC chemoresistance and that GDF15 can be targeted during chemotherapy, resulting in beneficial therapeutic outcomes.
