RESUMO

Cell death can be executed through distinct subroutines. PANoptosis is a unique inflammatory cell death modality involving the interactions between pyroptosis, apoptosis, and necroptosis, which can be mediated by multifaceted PANoptosome complexes assembled via integrating components from other cell death modalities. There is growing interest in the process and function of PANoptosis. Accumulating evidence suggests that PANoptosis occurs under diverse stimuli, for example, viral or bacterial infection, cytokine storm, and cancer. Given the impact of PANoptosis across the disease spectrum, this review briefly describes the relationships between pyroptosis, apoptosis, and necroptosis, highlights the key molecules in PANoptosome formation and PANoptosis activation, and outlines the multifaceted roles of PANoptosis in diseases together with a potential for therapeutic targeting. We also discuss important concepts and pressing issues for future PANoptosis research. Improved understanding of PANoptosis and its mechanisms is crucial for identifying novel therapeutic targets and strategies.

RESUMO

Aims: Programmed death-1 (PD-1) blockade is a vital therapy for solid tumors, but not all patients benefit. Identifying which patients will benefit from immunotherapy is a key focus in oncology research. Patients & Methods: This study analyzed the correlation between the number of peripheral lymphocytes and the efficacy and prognosis of immunotherapy in advanced malignant melanoma. Results: Patients with a partial response had significantly lower peripheral B cell levels, and patients with a lower number of B lymphocytes had a longer survival time. Conclusion: These results suggest that peripheral B cells are correlated with the efficacy of PD-1 antibody and prognosis and are thus potential biomarkers for the efficacy and prognosis of PD-1 antibody immunotherapy in malignant melanoma.


Immunotherapy is an important treatment for cancer patients with solid tumors. Because immunotherapy does not work equally well for everybody, an important area of research is to determine for which patients the treatment will work. Our study focused on skin cancer patients. We examined the relationship between the number of B cells (a type of immune cell) in patients' blood, and how well they responded to immunotherapy. We observed that patients who partially responded to treatment had lower levels of B cells. Additionally, patients who had a lower number of B cells also had a longer survival time. This could mean that looking at patients' B cell levels might be useful in working out how well they well respond to immunotherapy.

RESUMO

Akkermansia muciniphila (A. muciniphila), a gram-negative anaerobic bacterium, is selectively decreased in the fecal microbiota of patients with colorectal cancer (CRC), but its molecular mechanism in CRC development remains inconclusive. In this study, we first confirmed the inhibitory effect of A. muciniphila on CRC formation and analyzed the metabolic role of intestinal flora in human Polyps, A-CRA (advanced colorectal adenoma) and CRC samples. To better clarify the role of A. muciniphila in CRC development, a pseudo-germ-free (GF) azoxymethane (AOM)/dextran sulfate sodium (DSS) mouse model was established, followed by infection with or without A. muciniphila. Metabolomic analysis and RNA-seq analysis showed tryptophan-mediated aryl hydrocarbon receptor (AhR) was significantly down-regulated in A. muciniphila-infected CRC mice. Then, mice with intestinal specific AhR deficiency (AhRfl/fl Cre) were generated and were used in 2 murine models: AOM/DSS treatment as a model of carcinogen-induced colon cancer and a genetically induced model using ApcMin/+ mice. Notably, AhR deficiency inhibited CRC growth in the AOM/DSS and ApcMin/+ mouse model. Moreover, AhR deficiency inhibited, rather than enhanced, tumor formation and tumor-derived organoids in Apc-deficient cells both in vivo and in vitro by activating Wnt/ß-catenin signaling and TCF4/LEF1-dependent transcription. Furthermore, the antitumor effectiveness of A. muciniphila was abolished either in a human colon cancer tumor model induced by subcutaneous transplantation of AhR-silenced CRC cells, or AhR-deficienty spontaneous colorectal cancer model. In conclusion, supplementation with A. muciniphila. protected mice from CRC development by specifically inhibiting tryptophan-mediated AhR/ß-catenin signaling.

RESUMO

With the increasing incidence of esophageal cancer, its diagnosis and treatment have become one of the key issues in medical research today. However, the current diagnostic and treatment methods face many unresolved issues, such as low accuracy of early diagnosis, painful treatment process for patients, and high recurrence rate after recovery. Therefore, new methods for the diagnosis and treatment of esophageal cancer need to be further explored, and the rapid development of nanomaterials has brought new ideas for solving this problem. Nanomaterials used as drugs or drug delivery systems possess several advantages, such as high drug capacity, adjustably specific targeting capability, and stable structure, which endow nanomaterials great application potential in cancer therapy. However, even though the nanomaterials have been widely used in cancer therapy, there are still few reviews on their application in esophageal cancer, and systematical overview and analysis are deficient. Herein, we overviewed the application of nanodrug systems in therapy and diagnosis of esophageal cancer and summarized some representative case of their application in diagnosis, chemotherapy, targeted drug, radiotherapy, immunity, surgery and new therapeutic method of esophageal cancer. In addition, the nanomaterials used for therapy of esophageal cancer complications, esophageal stenosis or obstruction and oesophagitis, are also listed here. Finally, the challenge and the future of nanomaterials used in cancer therapy were discussed.

RESUMO

Objective: Pulmonary enteric adenocarcinoma (PEAC) is a rare subtype of pulmonary adenocarcinoma that lacks effective treatment. The purpose of this research was to investigate the clinical characteristics, treatment, and prognosis of PEAC, as well as the impact of relevant factors on survival, thus providing a reference for the clinical management of patients with this disease. Methods: For this study, we gathered clinical data from 26 patients with PEAC in the Affiliated Cancer Hospital of Zhengzhou University from June 2014 to June 2021. We used SEER*Stat software V8.3.5 to download the PEAC patients from the Surveillance, Epidemiology, and End Results (SEER) database. In total, 20 patients were identified. Clinical data, including general information, imaging findings, and treatment protocols, were obtained, together with a follow-up of disease regression. The relevant clinical data were then analyzed. Results: It included 12 males and 14 females out of 26 patients from China, whose mean age was (62.73 ± 11.89) years; 20 were in the lower lung, 11 were stage I-II, and 15 were stage III-IV. Five had EGFR mutations, and four had KRAS mutations. In terms of treatment, patients with stage I-II were primarily treated by surgery, and patients with stage III-IV were treated mostly by chemotherapy. We extended the follow-up date to January 2022. On completion of the follow-up visit, 11 patients died, and the remaining 15 patients survived. The overall survival (OS) of 26 patients was 2.0-76.0 months, while the mean was 53.1 months, and the median OS (mOS) was 38.0 months (95% CI:1.727-74.273). In the case of progression-free survival (PFS) times, it was 2.0-76.0 months, with a mean PFS of 31.0 months and a median PFS (mPFS) of 8.0 months (95% CI:4.333-11.667). The PFS of the 15 patients in stage III-IV was 2.0-17 months, while the mean PFS was 6.5 months and the mPFS was 6.0 months (95% CI:4.512-7.488). Out of the 20 patients identified in the SEER database, the average age was 69.9 years, with 14 males and 6 females. Of these patients, 8 were diagnosed with stage I-II, while the remaining 11 were diagnosed with stage III-IV. 10 underwent surgery, 4 received radiation therapy, and 9 received chemotherapy. The mean OS of the 20 patients was 67.5 months, mOS was 28.0 months (95% CI: 9.664- 46.336). For patients diagnosed with stage III-IV, the mean OS was 14.8 months and mOS was 20 months (95% CI: 4.713-35.287). Conclusion: PEAC is rare, and the prognosis is determined mainly by the stage; patients who undergo surgery in stage I-II have a better prognosis.

RESUMO

Background: Both apatinib and programmed death 1 (PD-1) monoclonal antibody (mAb) monotherapy have been licensed in China for the third-line treatment of advanced gastric cancer (AGC). However, whether the combination could improve the prognosis of patients with AGC after second-line treatment has not been evaluated. Methods: We retrospectively screened 892 patients with AGC who received third-line or later treatment from June 2016 to July 2021 at the Affiliated Cancer Hospital of Zhengzhou University and second People's Hospital of Pingdingshan. 166 patients who received apatinib plus PD-1 mAb, apatinib, or PD-1 mAb were included. Based on medical records and follow-up data, we analyzed the efficacy and safety of these three treatment options. Results: Patients received apatinib plus PD-1 mAb (n=49), apatinib monotherapy (n=63), or PD-1 mAb monotherapy (n=54). Apatinib plus PD-1 mAb showed significantly longer progression-free survival (PFS) and overall surivival (OS) compared with the apatinib monotherapy (PFS: 5.5 months versus 3.0 months; p=0.002; OS: 10 months versus 7.6 months; p=0.011) or PD-1 mAb monotherapy (PFS: 5.5 months versus 2.3 months; p=0.017; OS: 10 months versus 6.5 months; p=0.004). Apatinib plus PD-1 mAb showed higher ORR and DCR than the apatinib and PD-1 mAb monotherapy (ORR: 34.7% versus 6.3% versus 9.3%; p=0.001; DCR: 75.5% versus 44.4% versus 40.7%; p=0.001). Further subgroup analysis for PFS and OS shown consistent efficacy in most subgroups with apatinib plus PD-1 mAb versus apatinib monotherapy or PD-1 mAb monotherapy. Multivariate analyses suggested that apatinib plus PD-1 mAb was significantly associated with better PFS and OS. Most of the treatment-related toxicities were mild and tolerable. Conclusion: Compared with the monotherapy of either apatinib or PD-1 mAb, apatinib plus PD-1 mAb treatment yielded longer PFS and OS, and achieved significant higher ORR and DCR.

RESUMO

Background: Anlotinib is a novel tyrosine kinase inhibitor with promising anti-tumor activity in patients with advanced non-small cell lung cancer (NSCLC). The aim of this study was to evaluate the efficacy and safety of anlotinib maintenance therapy in patients with advanced NSCLC in real-world situation. Methods: We conducted a retrospective study on the patients with stage IIIb or IV NSCLC who visited our hospital between December 2016 and April 2020. They achieved an objective response or stable disease after first- or second- line treatment and then received switch maintenance therapy with anlotinib. Data were collected using automated data mining technology from electronic health records. Patients' demographic and clinical characteristics, median progression-free survival (PFS), median overall survival (OS), and adverse events were described, and preliminary analysis of efficacy predictors was analyzed. Results: Thirty-two patients were included in this study (20 patients in first-line treatment and 12 patients in second-line treatment). Median anlotinib maintenance time was 9 days (Q1-Q3: 3-22). The median PFS was 11.5 months, with 11.5 months in first-line treatment and 8.9 months in second-line treatment. The median OS was 12.0 months, with 16.4 months in first-line treatment group and 8.9 months in second-line treatment group. Grade 2-3 treatment-related adverse events were reported in 18.76% patients. No life-threatening adverse events were observed. Conclusion: Our results suggested that anlotinib maintenance therapy might be a potentially safe and efficacious option for patients who had benefited from first- or second-line treatment. However, our data are limited representative due to the small sample size; the efficacy of anlotinib maintenance therapy warrants further evaluation.

RESUMO

INTRODUCTION: As a novel third-generation EGFR tyrosine kinase inhibitor (TKI), SH-1028 (formerly oritinib) is developed to inhibit both sensitizing EGFR mutations and EGFR T790M mutation. METHODS: This was a multicenter, single-arm, open-label, phase 2 trial (NCT03823807). Eligible patients were those with advanced NSCLC with centrally confirmed EGFR T790M mutation who progressed after first- or second-generation EGFR TKIs or with primary EGFR T790M mutations. Each patient received SH-1028 tablets orally at 200 mg/d until disease progression or intolerable toxicity. Tumor response was evaluated every 6 weeks per the Response Evaluation Criteria in Solid Tumors, version 1.1. The primary end point was objective response rate by an independent review committee. The secondary end points were progression-free survival, overall survival (OS), disease control rate, safety, and so on. RESULTS: A total of 286 patients with EGFR T790M-positive advanced NSCLC were enrolled in this study, including 59 patients in part A (dose-verification study) and 227 patients in part B (second-line registration study). By data cutoff on September 17, 2021, the independent review committee-assessed objective response rate was 55.9% (95% confidence interval [CI]: 42.4-68.8) in part A and 60.4% (95% CI: 53.7-66.8) in part B. The median progression-free survival was 12.4 months (95% CI: 8.3-20.8) in part A and 12.6 months (95% CI: 9.7-15.3) in part B. The median OS was 26.0 months (95% CI: 23.3-not reached) in part A, and OS was immature in part B. Among the 286 patients, 44 of them experienced at least one grade 3 or higher treatment-related adverse event, with the most common ones as increased serum creatinine phosphokinase level (13 [4.5%]), diarrhea (six [2.1%]), and prolonged QT interval (three [1.0%]). Treatment-related skin rash was reported in 26 patients (9.1%), all grade 1 or 2. There was no interstitial lung disease reported in this study. CONCLUSIONS: SH-1028 is efficacious and tolerable in second-line treatment of patients with advanced NSCLC with positive EGFR T790M.

RESUMO

OBJECTIVE: For recurrent or metastatic endometrial cancer after second-line treatment, therapeutic options are limited. Anlotinib is a new multi-targeted tyrosine kinase inhibitor of tumor angiogenesis and growth. The aim of this study was to explore the efficacy and safety of anlotinib in patients with recurrent or metastatic endometrial cancer. METHODS: Patients with recurrent or metastatic endometrial cancer who received anlotinib or anlotinib plus pembrolizumab after second-line treatment between July 2017 and October 2020 were analyzed. Objective response rate, disease control rate, progression-free survival, overall survival, and safety were evaluated. RESULTS: A total of 56 patients were analyzed. The median age was 62 years (range 42-80). The median treatment of anlotinib was 5.9 cycles (range 2-21). The overall objective response rate was 42.9%, and the disease control rate was 75%. 44 (78.6%) patients received anlotinib monotherapy and 12 (21.2%) patients received anlotinib plus pembrolizumab. The objective response rate was 40.9% versus 50% (p=0.52) and the disease control rate was 72.7% versus 83.3% (p=0.59) in the monotherapy group and the combination therapy group, respectively. The median progression-free survival and overall survival from initiation of anlotinib therapy was 6 months (95% CI 4.89 to 7.11) and 13.3 months (95% CI 9.94 to 16.61), respectively. On multivariable Cox analysis, age (>60 vs ≤60 years) was an independent impact factor for both progression-free survival and overall survival, while prior lines of treatment (2 lines vs ≥3 lines) was an independent predictor of progression-free survival. The incidences of grade 3/4 adverse events were hypertension (10.7%), fatigue (7.1%), hand-foot syndrome (7.1%), proteinuria (3.6%), sore throat (3.6%), and hypothyroidism (3.6%). CONCLUSION: Anlotinib is effective and well tolerated in patients with recurrent or metastatic endometrial cancer. It may be considered a choice for patients younger than 60 years and who have had <3 lines of treatment.

RESUMO

Background: Apatinib is approved in China for the treatment of advanced gastric adenocarcinoma that had progressed or relapsed after standard systemic chemotherapy treatments. However, the effectiveness of Apatinib under real-world condition has not been evaluated and the drug performance under ideal and controlled circumstances has not been validated. In fact, genetic factors, poor healthcare access, social economic status, comorbidities compliance and other factors play significant role in drug performance under "real-world" conditions. Real-world experience can help validate the safety and efficacy of apatinib. Methods: In this observational, prospective study we evaluated the safety and efficacy of Apatinib in patient treated in China. Between March 2018 and March 2019, a total of 943 patients with gastric cancer treated with Apatinib were enrolled. Response Evaluation Criteria in Solid Tumors, version 1.1 and Common Terminology Criteria for Adverse Events, version 4.0 were used to evaluate efficacy and adverse effects. Results: The median progression-free survival (PFS) was 5.65 months (5.22-6.05 months), and the median overall survival (OS) was 11.47 months (10.41-12.52 months). Apatinib in combination with more than two agents was superior to single agent apatinib in overall response rate (ORR) [18.18% vs. 9.43%, 95% confidence interval (CI): 1.03-5.90] and disease control rate (DCR) (82.82% vs. 77.87%, 95% CI: 1.21-2.59). Apatinib in combination with single agent chemotherapy was also superior to apatinib alone with DCR (86.29% vs. 77.87%, 95% CI: 1.47-2.99) irrespective of the dose (250 or 500 mg). In the patient cohort who received a starting dose of 250 mg, the DCRs of the combined treatment and monotherapy groups were 86.22% vs. 80.00% (95% CI: 1.18-3.09), respectively. The most common treatment-emergent adverse events were anemia, anorexia and thrombocytopenia (66.28%, 37.75%, 36.06%, respectively). Conclusions: Efficacy of Apatinib in this observational study is promising and toxicities are manageable. Combination of Apatinib with chemotherapy agents has a higher response rate and better disease control at the expense of increased serious adverse events. Better OS can be achieved by receiving apatinib treatment earlier. As a supplement and further validation of explanatory randomized controlled trials, the real-world study reflects the real efficacy of apatinib in practical application.

RESUMO

Lung adenocarcinomas (LUADs) harbouring epidermal growth factor receptor (EGFR) mutations are generally unable to benefit from immune checkpoint inhibitors (ICIs) due to an immunosuppressive tumour microenvironment (TME) and a lower tumour mutation burden. Currently, no gene signature can comprehensively evaluate the TME and predict the prognosis of patients with EGFR-mutant LUAD. Using the Cancer Genome Atlas database of EGFR-mutant LUAD based on the immune score derived from the ESTIMATE algorithm, we divided 80 patients with EGFR-mutant LUAD samples into high and low immune score groups with different immune microenvironments. Subsequently, we screened 396 differentially expressed immune-related genes with prognostic value. The top Gene Ontology terms were significantly enriched in biological functions related to T cell differentiation, immune response, cell cycle, and cell proliferation, which are closely related to the immune microenvironment of tumours. In addition, the KEGG pathway enrichment analysis mainly focused on cell cycle, cell adhesion molecules, and cytokine-cytokine receptor interaction, which also had a relationship with the immune response. Subsequently, we identified a three-gene signature including BTLA, BUB1B, and CENPE using the LASSO Cox regression model. The three-gene signature could accurately identify patients at risk of EGFR-mutant LUAD in the training and validation sets and high-risk patients from both the sets exhibited significantly shorter overall survival (p=0.0053 and p=0.035, respectively). CIBERSORT was used to evaluate the abundance of immune cell infiltration in the EGFR-mutant LUAD microenvironment. The immune activity of B cells and macrophages was higher in the low-risk group, while the immune activity of natural killer cells and T cells was higher in the high-risk group. Thus, the three-gene signature closely related to immunosuppressive TME could predict the risk and prognosis in patients with EGFR-mutant LUAD.

RESUMO

BACKGROUND: Breast cancer is one of the common malignant tumors in women, which seriously affects women's physical and mental health and even life-threatening. The occurrence and development of breast cancer are closely related to genetic factors. Many studies have shown that human leukocyte antigen DRB1 is associated with the development of breast cancer, but lack evidence. This study aims to systematically evaluate the relationship between HLA-DRB1 gene polymorphism and breast cancer. METHODS: The retrieval time of this study was from the establishment of the database to February 2021. The retrieval databases included CNKI, Wanfang, VIP and China Biomedical Database, PubMed, Embase, Web of Science, and the Cochrane Library. The retrieval objects were observational studies on the relationship between HLA-DRB1 gene polymorphism and breast cancer (including case--control studies, cross-sectional studies, and cohort studies). The language restrictions were English and Chinese. Two researchers independently extracted the data and assessed the quality of the included studies, and Stata 16.0 software was used for statistical analysis. RESULTS: This study will systematically evaluate the relationship between HLA-DRB1 gene polymorphism and breast cancer based on existing studies. CONCLUSION: This study will explore the early warning signal of breast cancer genetic susceptibility, and provide evidence-based medical evidence for clarifying the role of HLA-DRB1 gene polymorphism in breast cancer.

RESUMO

BACKGROUND: Chemotherapy is the standard adjuvant treatment for colon cancer. Chinese herbal formula PRM1201 improves the efficacy of chemotherapy when used in combination with Cetuximab or Bevacizumab in patients with metastatic colorectal cancer. This study aims to explore the benefits of treatment with chemotherapy plus PRM1201 in the postoperative adjuvant setting. METHODS: In this parallel-group study, patients who had undergone curative resection for stage III colon cancer were randomly assigned to receive adjuvant chemotherapy (FOLFOX q2w for 6 months, or CapeOx q3w for 6 months) plus PRM1201 (chemo+PRM1201 group) or adjuvant chemotherapy plus placebo (chemo+placebo group). The primary endpoint was disease-free survival (DFS), and the secondary endpoints were quality of life (QOL) and toxicity. RESULTS: A total of 370 patients were randomly assigned to chemotherapy plus PRM1201 group (n = 184) and chemotherapy plus placebo group (n = 186). Up to October 30, 2019, 96 events of recurrence, metastasis, or death had been reported, of which 38 events were in the group of chemotherapy plus PRM1201 and 58 events in the chemo+placebo group. The 3-year DFS rate was 77.1 and 68.6% in the chemo+PRM1201 and chemo+placebo group, respectively (hazard ratio [HR], 0.63; 95% CI, 0.42 to 0.94). The QOL of patients in the chemo+PRM1201 group were significantly improved in terms of global quality of life, physical functioning, role functioning, emotional functioning, fatigue, and appetite loss. The incidence of grade 3 or 4 treatment-related adverse event (TRAEs) were similar between the two arms. CONCLUSIONS: Chemotherapy in combination with PRM1201 improved the adjuvant treatment of colon cancer. PRM1201 can be recommended as an effective option in clinical practice.

RESUMO

Long noncoding RNAs (lncRNAs) play crucial roles in regulating a variety of biological processes in lung adenocarcinoma (LUAD). In our study, we mainly explored the functional roles of a novel lncRNA long intergenic non-protein coding RNA 1426 (LINC01426) in LUAD. We applied bioinformatics analysis to find the expression of LINC01426 was upregulated in LUAD tissue. Functionally, silencing of LINC01426 obviously suppressed the proliferation, migration, epithelial-mesenchymal transition (EMT), and stemness of LUAD cells. Then, we observed that LINC01426 functioned through the hedgehog pathway in LUAD. The effect of LINC01426 knockdown could be fully reversed by adding hedgehog pathway activator SAG. In addition, we proved that LINC01426 could not affect SHH transcription and its mRNA level. Pull-down sliver staining and RIP assay revealed that LINC01426 could interact with USP22. Ubiquitination assays manifested that LINC01426 and USP22 modulated SHH ubiquitination levels. Rescue assays verified that SHH overexpression rescued the cell growth, migration, and stemness suppressed by LINC01426 silencing. In conclusion, LINC01426 promotes LUAD progression by recruiting USP22 to stabilize SHH protein and thus activate the hedgehog pathway.

RESUMO

OBJECTIVE: Anlotinib, an oral small-molecular tyrosine kinase inhibitor (TKI) on tumor angiogenesis and growth, has a wide spectrum of inhibitory effects on targets such as vascular endothelial growth factor receptors 2/3 (VEGFR2/3), etc. The efficacy and safety of anlotinib in the treatment of platinum-resistant or platinum-refractory ovarian cancer were evaluated. PATIENTS AND METHODS: Patients with platinum-resistant or platinum-refractory ovarian cancer that treated with anlotinib in the Affiliated Cancer Hospital of Zhengzhou University from May 2018 to March 2020 were included. Medical records were reviewed in terms of objective response, survival outcomes, and safety. RESULTS: A total of 38 patients were analyzed. The median progression-free survival and the median overall survival were 7.7 months (95% CI: 6.7-8.7) and 16.5 months (95% CI: 13.3-19.7), respectively. About 17 patients received anlotinib monotherapy, and the median progression-free survival was 7.7 months (95% CI: 6.3-9.1). A total of 19 cases received anlotinib plus chemotherapy with a median progression-free survival of 8.0 months (95% CI: 4.8-11.2). A total of 2 cases received anlotinib plus anti-PD-1 antibody pembrolizumab, and 1 case had partial response, the other progressive disease. The objective response rate was 42.1% while the disease control rate was 86.8%. A total of 5 patients experienced dose reduction from 12 mg to 10 mg because of adverse effects. The most common adverse effects were hypertension (31.6%), fatigue (28.9%), anorexia (26.3%) and hand-foot syndrome (23.7%). No treatment-related deaths were recorded. CONCLUSION: Anlotinib produced moderate improvements in progression-free survival and overall survival in patients with platinum-resistant or platinum-refractory ovarian cancer. It indicates that anlotinib maybe a new treatment option for patients with platinum-resistant or platinum-refractory ovarian cancer.

RESUMO

At present, treatment options for osimertinib resistance are very limited. Dual inhibition of the vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) significantly improved the progression-free survival (PFS) of advanced EGFR-mutant non-small cell lung cancer (NSCLC). After EGFR-tyrosine kinase inhibitor (TKI) resistance, EGFR-TKI continuation combined with VEGF inhibitors still had clinical benefits. It is unclear whether the addition of bevacizumab after osimertinib progresses will prolong the duration of the osimertinib benefit. We screened 1289 patients with NSCLC and finally included 96 patients to evaluate osimertinib combined with bevacizumab (osi + bev) versus chemotherapy combined with bevacizumab (che + bev) for patients with acquired resistance to osimertinib. The overall response rate (ORR) for osi + bev and chem + bev was 15.8% (6 of 38) and 20.7% (12 of 58), respectively. The median PFS for osi + bev and che + bev was 7.0 and 4.9 months (HR 0.415 95%CI: 0.252-0.687 p = 0.001). The median OS for osi + bev and che + bev was 12.6 and 7.1 months (HR 0.430 95%CI: 0.266-0.696 p = 0.001). Multivariate analyses showed that no brain metastases and osi + bev treatment after osimertinib resistance correlated with longer PFS (p = 0.044, p = 0.001), while the median PFS of osimertinib less than 6 months (p = 0.021) had a detrimental effect on sequent treatment. Only osi + bev treatment was identified as an independent predictor of OS (p = 0.001). The most common adverse events (AEs) of grade ≥3 were hypertension (13.2%) and diarrhea (10.5%) in the osi + bevacizumab group. Neutropenia (24.1%) and thrombocytopenia (19%) were the most common grade ≥3 AEs in the che + bev group. The overall incidence of serious AEs (grade ≥3) was significantly higher in the chemotherapy plus bevacizumab group. Our study has shown the superiority of osi + bev compared to che + bev after the failure of osimertinib, making it a preferred option for patients with acquired resistance to osimertinib.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Metastasis is the main cause of death in lung cancer patients. Circulating tumor cells (CTCs) may be an important target of metastasis intervention. Previous studies have shown that Jinfukang could prevent the recurrence and metastasis of lung cancer, and we have established a circulating lung tumor cell line CTC-TJH-01. However, whether Jinfukang inhibition of lung cancer metastasis is related to CTCs is still unknown. AIM OF THE STUDY: To further explore the mechanism of Jinfukang in anti-metastasis of lung cancer from the perspective of intervention of CTCs. MATERIALS AND METHODS: CTC-TJH-01 and H1975 cells were treated with Jinfukang. Cell viability was detected by CCK8, and the cell apoptosis was detected by flow cytometry. Transwell was used to detected cell migration and invasion. Cell anoikis was detected by anoikis detection kit. Protein expression was analysis by Western blot. RESULTS: Jinfukang could inhibit the proliferation, migration and invasion of CTC-TJH-01 and H1975 cells. Besides, Jinfukang could also induce anoikis in CTC-TJH-01 and H1975 cells. Analysis of the mRNA expression profile showed ECM-receptor interaction and focal adhesion were regulated by Jinfukang. Moreover, it was also find that Jinfukang significantly inhibited integrin/Src pathway in CTC-TJH-01 and H1975 cells. When suppress the expression of integrin with ATN-161, it could promote Jinfukang to inhibit migration and induce anoikis in CTC-TJH-01 and H1975 cells. CONCLUSIONS: Our results indicate that the migration and invasion of CTCs are inhibited by Jinfukang, and the mechanism may involve the suppression of integrin/Src axis to induce anoikis. These data suggest that Jinfukang exerts anti-metastatic effects in lung cancer may through anoikis.

RESUMO

BACKGROUND: Huangci Granule is a traditional Chinese medicine for treating metastatic colorectal cancer (mCRC). OBJECTIVE: To evaluate the efficacy and safety of Huangci Granule combination with chemotherapy and cetuximab (CET) or bevacizumab (BV) for treating mCRC. METHODS: We performed a randomized, controlled, and double-blind trial and recruited patients with mCRC who were planned to undergo chemotherapy combined with CET or BV. The treatment group was treated with Huangci Granule, while the control group was treated with placebo. Continuous treatment until disease progression, death, intolerable toxicity or up to 6 months. The primary endpoint was progression-free survival (PFS), and the secondary endpoint was quality of life and safety. RESULT: 320 patients were randomly assigned to receive treatment, including 200 first-line patients and 120 second-line patients. In the first-line treatment, the median PFS was 9.59 months (95% CI, 6.94-13.25) vs 6.89 months (95% CI, 4.99-9.52) in treatment group and control group (HR, 0.69; 95% CI, 0.50-0.97; P = 0.027). Chinese medicine was an independent factor affecting the PFS. In the second-line treatment, the median PFS was 6.51 months (95% CI, 4.49-9.44) vs 4.53 months (95% CI, 3.12-6.57) in the treatment group and control group (HR, 0.65; 95% CI, 0.45-0.95; P = 0.020). Compared with the control group, "role function," "social function," "fatigue," and "appetite loss" were significantly improved in the treatment (P < 0.05) and drug related grades 3 to 4 adverse events were less. CONCLUSION: Huangci Granule combined with chemotherapy and CET or BV can prolong the PFS of mCRC, improve the quality of life, reduce adverse reactions, and have good safety.

RESUMO

OBJECTIVE: To compare and analyze three therapies on patients with primary central nervous system lymphoma (PCNSL), aiming to provide evidences for future treatment and prognosis. METHODS: Clinical data of 26 cases of PCNSL with normal immune system confirmed by postoperative pathology were retrospectively analyzed. Among them there were six cases with operation only, nine cases with operation and radiotherapy, and 11 cases with operation, radiotherapy and chemotherapy, and their survival rate was compared as well. RESULTS: The survival time of patients with operation only, operation combined with radiotherapy and operation combined with radiotherapy and chemotherapy was 6-11 months, 15-24 months and 24-51 months, respectively. And their median survival time was only nine months, 21 months and 38 months, respectively. CONCLUSIONS: Operation combined with radiotherapy and chemotherapy can dramatically extend PCNSL patients' survival time, therefore, it can be regarded as the first-line therapy.
