RESUMO

CONTEXT: The Xihuang pill (XHP) is a traditional Chinese medicine formulation that has been historically used in the prevention and treatment of proliferative breast diseases. However, there is a lack of guidelines that offer recommendations for its clinical use. OBJECTIVE: The task force from the Chinese Guangdong Pharmaceutical Association aims to develop evidence-based guidelines for XHP to prevent and treat proliferative breast diseases. METHODS: We searched six Chinese and English electronic databases, including the China National Knowledge Infrastructure, the Chinese Scientific Journal Database, the Wanfang Medical Database, PubMed, and Embase, up to November 1, 2022. Publications (case reports, clinical observation, clinical trials, reviews) on using XHP to treat proliferative breast diseases were manually searched. The search terms were Xihuang pill, hyperplasia of the mammary gland, breast lump, and mastalgia. The writing team developed recommendations based on the best available evidence. RESULTS: Treatment should be customized based on syndrome identification. We recommend using XHP for the prevention and treatment of breast hyperplasia disease when a patient presents the following syndromes: concurrent blood stasis syndrome, concurrent phlegm-stasis syndrome, and concurrent liver fire syndrome. Safety indicators, including blood analysis and liver and kidney function monitoring, should be performed regularly during treatment. CONCLUSIONS: Current clinical evidence suggests that XHP can be used as a standalone treatment or in conjunction with other medications to prevent and manage breast hyperplasia diseases. More randomized controlled studies are warranted to establish high-quality evidence of its use.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: The Yi-Fei San-Jie pill (YFSJ) is a well-known Chinese medicine that has been used to treat non-small cell lung cancer in China for decades. AIM OF THE STUDY: Previous studies have shown that YFSJ combined with gefitinib can effectively inhibit the proliferation of gefitinib-resistant non-small cell lung cancer (NSCLC) cell lines by promoting apoptosis and autophagy, but the molecular biological mechanisms involved and whether YFSJ combined with gefitinib can have synergistic effects still need to be further explored. Thus, the present study aimed to establish an in silico and experimental framework to decipher the underlying mechanism by which YFSJ augments the efficacy of gefitinib in treating NSCLC. MATERIALS AND METHODS: Integrated approaches, including microarray analysis, network pharmacology, RNA sequencing, bioinformatics algorithm analysis and in vivo and in vitro experiments, were applied to elucidate the underlying mechanism. RESULTS: Analysis of microarray datasets indicated that gefitinib may play a role in the regulation of the epithelial-mesenchymal transition (EMT) of PC9 cells. EMT-related Gene Ontology (GO) terms and the MAPK pathway were found to be enriched in the differentially expressed genes (DEGs), and a decreasing trend was observed in the EMT score. Network pharmacology analysis revealed that the potential NSCLC-related targets of YFSJ also showed enrichment in EMT-related GO terms and the MAPK pathway. Experimental findings demonstrated that combined YFSJ-treated serum and gefitinib treatment significantly inhibited PC9 cell migration and invasion. In addition, the combined treatment dramatically reduced the tumour volume in an animal model. The effectiveness of the combination treatment surpassed that of gefitinib alone in both cell and animal experiments. RNA sequencing analysis revealed significant enrichment of DEGs in EMT-related GO terms for the gefitinib treatment group, YFSJ treatment group, and combination treatment group compared to the control group. Notably, the negative regulation of EMT showed significant enrichment in the DEGs of the combination treatment group. The MAPK pathway was significantly enriched among the different groups. Moreover, combined treatment with YFSJ and gefitinib may exert synergistic anti-NSCLC effects by inhibiting the p-p38 MAPK/GSK3ß signalling axis, subsequently suppressing downstream EMT processes. CONCLUSION: Combined treatment with YFSJ and gefitinib could enhance the sensitivity of NSCLC cells to gefitinib by suppressing EMT through the EGFR/p-p38 MAPK/GSK3ß signalling axis. YFSJ may serve as an important adjunctive medication for NSCLC patients receiving gefitinib treatment in clinical practice.

RESUMO

Tumor drug resistance emerges from the interaction of two critical factors: tumor cellular heterogeneity and the immunosuppressive nature of the tumor microenvironment (TME). Tumor-associated macrophages (TAMs) constitute essential components of the TME. M2-like TAMs are essential in facilitating tumor metastasis as well as augmenting the drug resistance of tumors. This review encapsulates the mechanisms that M2-like TAMs use to promote tumor drug resistance. We also describe the emerging therapeutic strategies that are currently targeting M2-like TAMs in combination with other antitumor drugs, with some still undergoing clinical trial evaluation. Furthermore, we summarize and analyze various existing approaches for developing novel drugs that target M2-like TAMs to overcome tumor resistance, highlighting how targeting M2-like TAMs can effectively stop tumor growth, metastasis, and overcome tumor drug resistance.

RESUMO

OBJECTIVE: Sarcopenia is a common condition among patients with cancer. To better understand the prevalence of sarcopenia in patients with head and neck cancer (HNC), we analysed the risk factors of sarcopenia and developed a theoretical foundation for further development of sarcopenia prevention and treatment strategies. METHODS: Six hundred and seventeen patients with HNC were recruited for this cross-sectional observational study, and the data were analyzed using logistic regression analyses. The bioelectrical impedance analysis (BIA) was used to measure skeletal muscle mass, and sarcopenia was diagnosed according to the 2019 diagnostic criteria of the Asian Sarcopenia Working Group (AWGS). RESULTS: Among the 617 patients enrolled in the study, 115 (18.6%) had sarcopenia. The prevalence of sarcopenia was 29.1% in males and 8% in females. In the multivariate analysis, older age (OR = 12.266, 95% CI: 3.864-38.934, p < 0.01), body fat (OR = 1.775, 95% CI: 1.511-2.084, p < 0.01), and sex (OR = 138.659, 95% CI: 42.382-453.642, p < 0.01) were independent risk factors for sarcopenia. Body mass index (BMI) (OR = 0.137, 95% CI: 0.09-0.21, p < 0.01), and total body water/fat free mass (TBW/FFM) (OR = 0.122, 95% CI: 0.031-0.474, p < 0.01) were protective factors for sarcopenia; we observed that sarcopenia decreased with increasing BMI and TBW/FFM. CONCLUSIONS: Male sex, advanced age, and excess body fat were identified as risk factors for sarcopenia in patients with HNC, whereas a higher BMI and TBW/FFM acted as protective factors against sarcopenia in these patients.

RESUMO

Savolitinib is a highly selective mesenchymal-epithelial transition (MET) tyrosine kinase inhibitor (TKI). Based on its significant efficacy shown in clinical studies, savolitinib was conditionally approved for marketing in China on 22 June 2021, for the treatment of advanced non-small cell lung cancer (NSCLC) with MET 14 exon skipping mutation. Additionally, many studies showed that MET TKIs were equally effective in patients with advanced solid tumors with MET gene amplification or MET protein overexpression. Several relevant registered clinical studies are in progress. The most common adverse reactions (ARs) due to savolitinib administration are nausea, vomiting, peripheral edema, pyrexia, and hepatotoxicity. This consensus was developed through two rounds of extensive national surveys involving multidisciplinary experts in China, aiming to guide clinicians to prevent and treat various ARs scientifically, and improve the efficacy of the drug and the quality of life of patients.

RESUMO

Paraneoplastic Cushing's syndrome (PCS) is a rare, but clinically important feature of small cell lung cancer (SCLC) that is associated with even worse prognosis. To identify key considerations in comprehensive management of SCLC patients complicated with PCS, we conducted a systematic review of relevant reports on PubMed and Web of Science, focusing on SCLC with PCS cases. The systematic review analyzed 61 reports published between 1985 and 2022 with a total of 157 SCLC patients included. Out of the 157 patients, 132 (84.1%) patients across 58 (95.1%) reports were diagnosed with ectopic Cushing's syndrome. The immunohistochemical (IHC) staining for adrenocorticotropic hormone (ACTH) was performed on 30 (19.1%) patients across 22 (36.1%) reports and demonstrated encouraging performance. For treatment, chemotherapy and ketoconazole were utilized in 50 (81.97%) and 24 (39.34%) reports, respectively. Regarding cause of death, infection and cancer were equally frequent, each being recorded in 17 (27.87%) reports. To conclude, the majority of PCS cases in SCLC patients were caused by ectopic hormone secretion. In order to make a differential diagnosis, it is recommended to utilize IHC staining for a specific hormone such as ACTH or corticotropin-releasing hormone. In the comprehensive treatment of SCLC with PCS patients, effective management of hypercortisolism and potent safeguarding against infection play two crucial roles. Ultimately, further confirmations are required regarding the specificity and accuracy of IHC staining technique as well as the efficacy and safety of immunotherapy in the treatment of SCLC with PCS patients.

RESUMO

Patients treated with immune checkpoint inhibitors (ICIS) are prone to immune related adverse events (irAEs), making it important to pay attention to these adverse events. Herein, we report a case of onychopathy after treatment of extensive small cell lung cancer (ES-SCLC) with durvalumab; this is the first report of onychopathy caused by durvalumab in a patient with lung cancer. The change in the patient's nails mainly manifested in the form of pigmentation and the thickening of the nails. Antifungal ointment was ineffective, and these changes were unrelated to malnutrition or any other factors. In addition, this case shows that onychopathy may occur within 2 years after treatment, indicating that these patients need long-term follow-up.

RESUMO

BACKGROUND: The impact of sarcopenia on the outcome of patients with left-sided colon and rectal cancer has not been exhaustively investigated. Thus, the present study was performed to evaluate the effect of sarcopenia on the outcome of patients with left-sided colon and rectal cancer. METHODS: Patients with pathologically diagnosed stage I, II and III left-sided colon or rectal cancer who had undergone curative surgery between January 2008 and December 2014 were retrospectively reviewed. The psoas muscle index (PMI) identified by 3D-image analysis of computed tomographic images was the criterion used to diagnose sarcopenia. The cut-off value recommended by Hamaguchi (PMI value < 6.36 cm2/m2 for men and < 3.92 cm2/m2 for women) was adopted to confirm the diagnosis of sarcopenia. According to the PMI, each patient was divided into the sarcopenia group (SG) or the nonsarcopenia group (NSG). Then, the SG was compared with the NSG in terms of postoperative outcomes. RESULTS: Among the 939 patients included, 574 (61.1%) were confirmed to have preoperative sarcopenia. Initially, it was demonstrated that the SG was not significantly different from the NSG in terms of most baseline characteristics except for a lower body mass index (BMI) (P < 0.001), a larger tumour size (P < 0.001) and more weight loss (more than 3 kg in the last three months) (P = 0.033). The SG had a longer hospital stay after surgery (P = 0.040), more intraoperative blood transfusions (P = 0.035), and higher incidence of anastomotic fistula (P = 0.027), surgical site infection (SSI) (P = 0.037) and hypoalbuminemia (P = 0.022), 30-day mortality (P = 0.042) and 90-day mortality (P = 0.041). The SG had significantly worse overall survival (OS) (P = 0.016) and recurrence-free survival (RFS) (P = 0.036) than the NSG. Subsequently, Cox regression analysis revealed that preoperative sarcopenia was an independent predictive factor for worse OS (P = 0.0211, HR = 1.367, 95% CI: 1.049-1.782) and RFS (P = 0.045, HR = 1.299, 95% CI: 1.006-1.677). CONCLUSION: Preoperative sarcopenia adversely affects the outcome of patients with left-sided colon and rectal cancer, and preoperative nutrition supplementation may help us improve their long-term and short-term outcomes.

RESUMO

PURPOSE: PD-1 blockade plus chemotherapy has become the new standard of care in patients with untreated advanced non-small cell lung cancer (NSCLC), whereas predictive biomarkers remain undetermined. EXPERIMENTAL DESIGN: We integrated clinical, genomic, and survival data of 427 NSCLC patients treated with first-line PD-1 blockade plus chemotherapy or chemotherapy from two phase III trials (CameL and CameL-sq) and investigated the predictive and prognostic value of HLA class I evolutionary divergence (HED). RESULTS: High HED could predict significantly improved objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) in those who received PD-1 blockade plus chemotherapy [in the CameL trial, ORR: 81.8% vs. 53.2%; P = 0.032; PFS: hazard ratio (HR), 0.47; P = 0.012; OS: HR, 0.40; P = 0.014; in the CameL-sq trial, ORR: 89.2% vs. 62.3%; P = 0.007; PFS: HR, 0.49; P = 0.005; OS: HR, 0.38; P = 0.002], but not chemotherapy. In multivariate analysis adjusted for PD-L1 expression and tumor mutation burden, high HED was independently associated with markedly better ORR, PFS, and OS in both trials. Moreover, the joint utility of HED and PD-L1 expression showed better performance than either alone in predicting treatment benefit from PD-1 blockade plus chemotherapy. Single-cell RNA sequencing of 58,977 cells collected from 11 patients revealed that tumors with high HED had improved antigen presentation and T cell-mediated antitumor immunity, indicating an inflamed tumor microenvironment phenotype. CONCLUSIONS: These findings suggest that high HED could portend survival benefit in advanced NSCLC treated with first-line PD-1 blockade plus chemotherapy. See related commentary by Dimou, p. 4706.

RESUMO

BACKGROUND: Chinese herbal formulae has multiple active constituents and targets, and the good clinical response is encouraging more scientists to explore the bio-active ingredients in such complex systems. Yi-Fei-San-Jie formula (YFSJF) is commonly used to treat patients with lung cancer in South China; however, its bio-active ingredients remain unknown. PURPOSE: We investigated the bio-active ingredients of the YFSJF using a novel comprehensive strategy. METHODS: A549 cell extraction coupled with ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS/MS) was used for the screening of potential bio-active ingredients. Network pharmacology approach and molecular dynamics simulation were performed for the screening of targets. Surface plasmon resonance (SPR) assay and molecular biology techniques were used to verify the targets. RESULTS: Nine A549 cell membrane-binding compounds were identified through cell extraction/UPLC-MS/MS. Five compounds, namely ginsenoside Ro, ginsenoside Rb1, ginsenoside Rc, peimisine, and peimine were cytotoxic to A549 cells, and they were considered the bio-active ingredients of the YFSJF in vitro. Network pharmacology analysis revealed that TGFBR2 is the key target and the TGFß pathway is the key pathway targeted by YFSJF in non-small cell lung cancer. Peimisine showed an affinity to TGFBR2 using molecular docking and dynamic stimulation, which was confirmed using surface plasmon resonance spectroscopy. The molecular biology-based analysis further confirmed that peimisine targets TGFBR2 and can reverse A549 epithelial-mesenchymal transition by inhibiting the TGFß pathway. CONCLUSION: Taken together, cell extraction/UPLC-MS/MS, network pharmacology, and molecular biology-based analysis comprise a feasible strategy to explore active ingredients in YFSJF.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: The Chinese herbal prescription Yi-Fei San-Jie pill (YFSJ) has been used for adjuvant treatment in patients with lung cancer for a long time. AIM OF THE STUDY: Reports have indicated that the combination of gefitinib (Gef) with YFSJ inhibits the proliferation of EGFR-TKI-resistant cell lines by enhancing cellular apoptosis and autophagy in non-small cell lung cancer (NSCLC). However, the molecular mechanisms underlying the effect of YFSJ on EGFR-TKI resistance and related metabolic pathways remain to be explored. MATERIALS AND METHODS: In our report, ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), metabolomics, network pharmacology, bioinformatics, and biological analysis methods were used to investigate the mechanism. RESULTS: The UPLC-MS/MS data identified 42 active compounds of YFSJ extracts. YFSJ extracts can enhance the antitumor efficacy of Gef without hepatic and renal toxicity in vivo. The analysis of the metabolomics pathway enrichment revealed that YFSJ mainly affected the tyrosine metabolism pathway in rat models. Moreover, YFSJ has been shown to reverse Gef resistance and improve the effects of Gef on the cellular viability, migration capacity, and cell cycle arrest of NSCLC cell lines with EGFR mutations. The results of network pharmacology and molecular docking analyses revealed that tyrosine metabolism-related active compounds of YFSJ affect EGFR-TKIs resistance in NSCLC by targeting cell cycle and the MET/EGFR signaling pathway; these findings were validated by western blotting and immunohistochemistry. CONCLUSIONS: YFSJ inhibits NSCLC by inducing cell cycle arrest in the G1/S phase to suppress tumor growth, cell viability, and cell migration through synergistic effects with Gef via the tyrosine metabolic pathway and the EGFR/MET signaling pathway. To summarize, the findings of the current study indicate that YFSJ is a prospective complementary treatment for Gef-resistant NSCLC.

RESUMO

Checkpoint inhibitors are effective in recurrent/metastatic nasopharyngeal cancer (R/M NPC). RATIONALE-309 (NCT03924986) randomized 263 treatment-naive R/M NPC patients to tislelizumab or placebo every 3 weeks (Q3W), plus chemotherapy (Q3W for 4-6 cycles). At interim analysis, progression-free survival (PFS) was significantly longer with tislelizumab-chemotherapy versus placebo-chemotherapy (hazard ratio: 0.52; 95% confidence interval: 0.38, 0.73; p < 0.0001). PFS benefit for tislelizumab-chemotherapy versus placebo-chemotherapy was observed regardless of programmed death-ligand 1 expression. PFS after next line of treatment and overall survival showed favorable trends for tislelizumab-chemotherapy versus placebo-chemotherapy. The safety profile was similar between arms. Gene expression profiling (GEP) identified immunologically "hot" tumors, and showed an activated dendritic cell (DC) signature was associated with tislelizumab-chemotherapy PFS benefit. Our results support that tislelizumab-chemotherapy should be considered as first-line treatment for R/M NPC, and GEP and activated DC signature results may help identify patients who might benefit most from immunochemotherapy treatment.

RESUMO

Background: KL-A167 is a fully humanized monoclonal antibody targeting programmed cell death-ligand 1. This phase 2 study aimed to evaluate the efficacy and safety of KL-A167 in Chinese patients with previously treated recurrent or metastatic (R/M) nasopharyngeal carcinoma (NPC). Methods: This was a multicentre, single-arm, phase 2 study of KL-A167 in R/M NPC (KL167-2-05-CTP) (NCT03848286), conducted at 42 hospitals across the People's Republic of China. Eligible patients had histologically confirmed non-keratinising R/M NPC, and had failed at least two lines of chemotherapy. Patients received KL-A167 900mg intravenously once every 2 weeks until confirmed disease progression, intolerable toxicity, or withdrawal of informed consent. The primary endpoint was objective response rate (ORR) assessed by the independent review committee (IRC) according to RECIST v1.1. Findings: Between Feb 26th, 2019 and Jan 13th, 2021, 153 patients were treated. Totally, 132 patients entered full analysis set (FAS) and were evaluated for the efficacy. As of data cutoff date on Jul 13th, 2021, the median follow-up time was 21.7 months (95%CI 19.8-22.5). For FAS population, the IRC-assessed ORR was 26.5% (95%CI 19.2-34.9%), and disease control rate (DCR) was 56.8% (95%CI 47.9-65.4%). Median progression-free survival (PFS) was 2.8 months (95%CI 1.5-4.1) . Median duration of response was 12.4 months (95%CI 6.8-16.5), and median overall survival (OS) was 16.2 months (95%CI 13.4-21.3). When using the cutoff of 1000 copies/ml, 5000 copies/ml and 10,000 copies/ml for plasma EBV DNA titer, baseline low plasma EBV DNA was consistently related with better DCR, PFS and OS. Dynamic change of plasma EBV DNA was significantly associated with ORR and PFS. Among 153 patients, treatment related-adverse events (TRAEs) occurred in 73.2% of patients, and grade ≥3 TRAEs were in 15.0% of patients. No TRAE leading to death was reported. Conclusion: In this study, KL-A167 showed promising efficacy and an acceptable safety profile in patients with previously treated R/M NPC. Baseline plasma EBV DNA copy number might be a potentially useful prognostic biomarker for KL-A167 treatment, and post-treatment EBV DNA decrease might be correlated with better response to KL-A167.

RESUMO

Background: Cancer of unknown primary (CUP), which accounts for 3%-5% of new cancer cases every year, involves the presence of a type of histologically confirmed metastatic tumors whose primary site cannot be confirmed by conventional diagnostic methods. This difficulty in identifying the primary site means that CUP patients fail to receive precisely targeted therapy. Most patients are treated with empiric chemotherapy, with a median survival of 6 months and even poorer prognosis within an unfavorable subset of CUP. Case report: An 80-year-old woman presented with masses in the abdomen. Following comprehensive imagological and immunohistochemical examinations, she was diagnosed with CUP. She emphatically declined chemotherapy; thus, anlotinib has been administered with patient consent since 02/07/2019, and stable disease (SD) was observed for 2 years. During subsequent treatment, a large genomic rearrangement in BRCA1 was identified in the patient via NGS, and SD was observed for a further 6 months following olaparib treatment. The type of LGR identified in this patient was discovered to be BRCA1 exon 17-18 inversion (inv), which has never been previously reported. Conclusion: For CUP patients, a chemo-free regimen seems to be acceptable as a first-line treatment, and NGS-guided targeted treatment could improve patient outcomes.

RESUMO

Background: Jian Pi Sheng Sui Gao (JPSSG), a Chinese traditional herbal paste, possesses certain efficacy in patients with cancer-related fatigue (CRF); however, its related mechanism remains unclear. Hence, network pharmacology analysis, followed by in vivo and in vitro experiments were conducted in this study with the aim to evaluate the effect of JPSSG on CRF and clarify its potential mechanism. Methods: Network pharmacology analysis was performed. Subsequently, 12 mice were injected with CT26 cells to establish CRF mouse models and randomly divided into a model group (n=6) and JPSSG group (n=6); meanwhile, another 6 normal mice served as a control group. Then, 3.0 g/kg JPSSG was given to mice in JPSSG group for 15 days, while mice in the n control and model groups received phosphate-buffered saline (PBS) of the same volume for 15 days. For the in vitro experiment, CT26 conditioned medium (CM) was established; meanwhile, the mitochondrial damage model was constructed through C2C12 myotubes stimulated with H2O2. C2C12 myotubes were divided into 5 groups: control group (without treatment), CM group, CM + JPSSG group, H2O2 group, and H2O2 + JGSSP group. Results: Network pharmacology analysis identified 87 bioactive compounds and 132 JPSSG-CRF interaction targets. Moreover, according to the Kyoto Encyclopedia of Genes and Genomes enrichment analysis and the subsequent in vivo and in vitro experiments, JPSSG activated adenosine 5'-monophosphate-activated protein kinase-silent-information-regulator factor 2-related-enzyme 1 (AMPK-SIRT1) and hypoxia-inducible factor-1 (HIF-1) signaling pathways during CRF. Moreover, the in vivo experiment showed that JPSSG attenuated CRF in mice, reflected by increased distance traveled, mobile time in open field test, and swimming time in exhaustive swimming test, and decreased absolute rest time and tail suspension test in the JPSSG group (vs. model group). Furthermore, JPSSG upregulated gastrocnemius weight, adenosine triphosphate (ATP), superoxide dismutase (SOD), and the cross-sectional area of the gastrocnemius. With regard to in vitro study, JPSSG elevated cell viability, B-cell lymphoma-2, ATP, SOD, and mitochondrial membrane potential, while it decreased apoptosis rate, cleaved-caspase3, malondialdehyde, and reactive oxygen species in C2C12 myotubes. Conclusions: JPSSG ameliorates CRF via alleviating skeletal myoblast cell apoptosis, oxidative stress, and mitochondrial dysfunction in an AMPK-SIRT1- and HIF-1-dependent manner.

RESUMO

Background: The incidence of cancer-related fatigue (CRF) is increasing, but its lack of clear pathogenesis makes its prevention and treatment difficult. Therefore, it is of great significance to clarify the pathogenesis of CRF and find effective methods to treat it. Methods: The CRF model was established by intraperitoneal injection of LLC cells in ICR mice to explore the pathogenesis of CRF and verify the therapeutic effect of the Yifei-Sanjie pill (YFSJ). The active components of YFSJ were found by LC/MS, the in vitro inflammatory infiltration model of skeletal muscle was constructed by TNF-α and C2C12 myoblasts, and the results of in vivo experiments were verified by this model. Results: Behavioral analysis results showed that YFSJ alleviated CRF; histological examination results showed that YFSJ could reverse the tumor microenvironment leading to skeletal muscle injury; ELISA and RNA-seq results showed that the occurrence of CRF and the therapeutic effect of YFSJ were closely related to the tumor inflammatory microenvironment; IHC and WB results showed that the occurrence of CRF and the therapeutic effect of YFSJ were closely related to the Stat3-related signaling pathway and autophagy. Conclusions: YFSJ can reduce the level of inflammation in the tumor microenvironment in vivo, inhibit the abnormal activation of the Stat3/HIF-1α/BNIP3 signaling pathway induced by tumor-related inflammation, thereby inhibiting the overactivation of mitophagy in skeletal muscle, and finally alleviate CRF. Quercetin, one of the components of YFSJ, plays an important role in inhibiting the phosphorylation activation of Stat3.

RESUMO

INTRODUCTION: In CameL phase 3 study (ClinicalTrials.gov: NCT03134872), addition of camrelizumab to first-line chemotherapy significantly improved the progression-free survival in patients with stages IIIB to IV nonsquamous NSCLC. Here, we present outcomes after a minimum follow-up of 43.9 months since last patient randomization. METHODS: Eligible patients were randomized 1:1 to 4 to 6 cycles of camrelizumab plus carboplatin and pemetrexed or chemotherapy alone every 3 weeks, followed by maintenance camrelizumab plus pemetrexed or pemetrexed only (n = 205 and 207, respectively). Total camrelizumab exposure was up to 2 years. RESULTS: As of January 31, 2022, camrelizumab plus chemotherapy exhibited substantially improved overall survival over chemotherapy alone (median, 27.1 versus 19.8 mo; hazard ratio = 0.72 [95% confidence interval: 0.57-0.92]). In the chemotherapy-alone group, 95 patients (45.9%) crossed over to camrelizumab monotherapy. After adjustment for crossover, the survival benefit with camrelizumab plus chemotherapy was more pronounced (adjusted hazard ratio = 0.55 [95% confidence interval: 0.42-0.71]). In camrelizumab plus chemotherapy group, 33 patients completed 2 years of camrelizumab. Objective response rate was 97.0%, with ongoing responses in 17 of the 32 responses (53.1%), and 93.9% (31 of 33) of the patients were alive at data cutoff. Safety profiles were consistent with the previous report, and no obvious evidence of cumulative toxicity was found with long exposure to camrelizumab. CONCLUSIONS: Camrelizumab plus carboplatin and pemetrexed provides long-term survival benefit over chemotherapy, with manageable toxicity and remarkable and durable response in patients receiving 2 years of camrelizumab, further supporting camrelizumab combination as first-line treatment for advanced nonsquamous NSCLC.
