Desmoplastic small round cell tumor (DSRCT) is a rare, highly aggressive malignancy with distinctive histological features: a nesting pattern of cellular growth within dense desmoplastic stroma, occurring in young population with male predominance. The mean survival period is only about 1.5-2.5 years. The tumor has co-expressed epithelial, muscle, and neural markers in immunohistochemical studies. This work reports a 27-year-old man presenting with hematemesis and chronic constipation. Serial studies including endoscopy, upper gastrointestinal series, abdominal computed tomography and barium enema study showed disseminated involvement of visceral organs. The patient underwent aggressive surgery and received postoperative adjuvant chemotherapy consisting of 5-fluorouracil, cyclophosphamide, etoposide, doxorubicin, and cisplatin. He survived without any disease for 20 mo after the surgery. No standard treatment protocol has been established. Aggressive surgery combined with postoperative multi-agent adjuvant chemotherapy is justified not only to relieve symptoms but also to try to improve the outcome in this advanced DSRCT young patient. 展开更多

In China,lung cancer is a primary cancer type with high incidence and mortality.Risk factors for lung cancer include tobacco use,family history,radiation exposure,and the presence of chronic lung diseases.Most early-stage non-small cell lung cancer(NSCLC)patients miss the optimal timing for treatment due to the lack of clinical presentations.Population-based nationwide screening programs are of significant help in increasing the early detection and survival rates of NSCLC in China.The understanding of molecular carcinogenesis and the identification of oncogenic drivers dramatically facilitate the development of targeted therapy for NSCLC,thus prolonging survival in patients with positive drivers.In the exploration of immune escape mechanisms,programmed cell death protein 1(PD-1)/programmed death-ligand 1(PD-L1)inhibitor monotherapy and PD-1/PD-L1 inhibitor plus chemotherapy have become a standard of care for advanced NSCLC in China.In the Chinese Society of Clinical Oncology’s guidelines for NSCLC,maintenance immunotherapy is recommended for locally advanced NSCLC after chemoradiotherapy.Adjuvant immunotherapy and neoadjuvant chemoimmunotherapy will be approved for resectable NSCLC.In this review,we summarized recent advances in NSCLC in China in terms of epidemiology,biology,molecular pathology,pathogenesis,screening,diagnosis,targeted therapy,and immunotherapy。 展开更多

Studies in the past few years have provided compelling evidence for the critical role of aberrant Signal Transducer and Activator of Transcription 3 (STAT3) in malignant transformation and tumorigenesis. Thus, it is now generally accepted that STAT3 is one of the critical players in human cancer formation and represents a valid target for novel anticancer drug design. This review focuses on aberrant STAT3 and its role in promoting tumor cell survival and sup- porting the malignant phenotype. A brief evaluation of the current strategies targeting STAT3 for the development of novel anticancer agents against human tumors harboring constitutively active STAT3 will also be presented. 展开更多

The successes achieved by chimeric antigen receptor-modified T (CAR-T) cells in hematological malignancies raised the pos- sibility of their use in non-small lung cancer (NSCLC). In this phase I clinical study (NCT01869166), patients with epidermal growth factor receptor (EGFR)-positive (〉50% expression), relapsed/refractory NSCLC received escalating doses of EGFR-targeted CAR-T cell infusions. The EGFR-targeted CAR-T cells were generated from peripheral blood after a 10 to 13-day in vitro expansion. Serum cytokines in peripheral blood and copy numbers of CAR-EGFR transgene in peripheral blood and in tissue biopsy were monitored periodically. Clinical responses were evaluated with RECISTI.1 and im- mune-related response criteria, and adverse events were graded with CTCAE 4.0. The EGFR-targeted CAR-T cell infusions were well-tolerated without severe toxicity. Of 11 evaluable patients, two patients obtained partial response and five had stable disease for two to eight months. The median dose of transfused CAR+ T cells was 0.97x 10^7 cells kg J (interquar- tile range (IQR), 0.45 to 1.09x 10^7 cells kg 1). Pathological eradication of EGFR positive tumor cells after EGFR-targeted CAR-T cell treatment can be observed in tumor biopsies, along with the CAR-EGFR gene detected in tumor-infiltrating T cells in all four biopsied patients. The EGFR-targeted CAR-T cell therapy is safe and feasible for EGFR-positive advanced re- lapsed/refractory NSCLC. 展开更多

Background:On May 8,2018,the China National Medical Products Administration(NMPA)approved anlotinib,an orally administered anti-angiogenesis inhibitor,for the treatment of patients with advanced non-small cell lung can-cer(NSCLC)who have progressed after treatment with two or more lines of prior systemic chemotherapy.Main body of the abstract:China NMPA reviewed and inspected a regional double-blinded,placebo-controlled,Phase III trial comparing the overall survival(OS)of NSCLC patients between the anlotinib and placebo arms.A total of 437 patients were randomized(2:1)to receive either anlotinib(n=294)or placebo(n=143)once daily on a 2-week on and 1-week off schedule.Patients with epidermal growth factor receptor(EGFR)or activating anaplastic lymphoma kinase(ALK)genomic tumor aberrations should have disease progression on NMPA-approved therapy.Anlotinib is the first NMPA-approved drug for patients with advanced NSCLC who have progressed on at least two lines of prior systemic chemotherapies in China.The approval was based on a statistically and clinically significant improvement in median OS with anlotinib(9.46 months)compared with placebo[6.37 months;hazard ratio(HR])=0.70,95%confidence interval(CI)=0.55-0.89;two-sided log-rank P=0.002].The confirmed objective response rate(ORR)was 9.2%in the anlotinib arm and 0.7%in the placebo arm.The median duration of response(DoR)was 4.83 months,with a 95%CI of 3.31-6.97 months.The toxicity profile of anlotinib was consistent with that of known anti-angiogenesis inhibitors.Common adverse drug reactions(ADRs)in anlotinib-treated patients included hypertension(67.4%),hand-foot syndrome(43.9%),hemoptysis(14.0%),thyroid stimulating hormone(TSH)elevation(46.6%),and corrected QT interval(QTc)prolongation(26.2%).Short conclusion:Anlotinib demonstrated a clinically significant OS prolongation as a novel therapeutic option for advanced or metastatic NSCLC following at least two lines of chemotherapy. 展开更多

However the mechanism behind is not clear. Here we have for the first time developed a novel CD146 blockade system using CD146 siRNA to study its function on endothelial cells. Our data showed that CD146 siRNA specifically blocked the expression of CD146 on both mRNA and protein levels, leading to the significant suppression of HUVEC proliferation, adhesion and migration. These results demonstrate that CD146 plays a key role in vascular endothelial cell activity and angiogenesis, and CD146 siRNA can be used as a new inhibitor for anti-angiogenesis therapy. 展开更多

Objective:Cancer-associated inflammation and coagulation cascades play vital roles in cancer progression and survival.In this study,we investigated the significance of the combination of preoperative fibrinogen and the neutrophil-to-lymphocyte ratio(NLR)in predicting the survival of patients with non-small cell lung cancer(NSCLC).Methods:We retrospectively enrolled 589 patients with NSCLC who underwent surgery.The univariate and multivariate Cox survival analyses were used to evaluate the prognostic indicators,including the combination of fibrinogen and NLR(F-NLR).The cut-off values for fibrinogen,NLR,and clinical laboratory variables were defined by the receiver operating characteristic(ROC)curve analysis.According to the ROC curve,the recommended cut-off values for fibrinogen and the NLR were 3.48 g/L and 2.30,respectively.Patients with both a high NLR(≥2.30)and hyperfibrinogenemia(≥3.48 g/L)were given a score of 2,whereas those with one or neither were scored as 1 or 0,respectively.Results:Our results showed that F-NLR was an independent prognostic indicator for disease-free survival(DFS)[hazard ratio(HR),1.466;95%confidence interval(CI),1.243–1.730;P<0.001]and overall survival(OS)(HR,1.512;95%CI,1.283–1.783;P<0.001).The five-year OS rates were 66.1%,53.5%,and 33.3%for the F-NLR=0,F-NLR=1,and F-NLR=2,respectively(P<0.001).Correspondingly,their five-year DFS rates were 62.2%,50.3%,and 30.4%,respectively(P<0.001).In the subgroup analyses of the pathological stages,the F-NLR level was significantly correlated with DFS and OS in stage I and IIIA cancers.Conclusions:Preoperative F-NLR score can be used as a valuable prognostic marker for patients with resectable early-stage NSCLC. 展开更多

Lung cancer mortality has decreased over the past decade and can be partly attributed to advances in targeted therapy and immunotherapy.Immune checkpoint inhibitors(ICIs)have rapidly evolved from investigational drugs to standard of care for the treatment ofmetastatic non-small cell lung cancer(NSCLC).In particular,antibodies that block inhibitory immune checkpoints,such as programmed cell death protein 1(PD-1)and programmed cell death 1 ligand 1(PD-L1),have revolutionized the treatment of advanced NSCLC,when administered alone or in combination with chemotherapy.Immunotherapy is associated with higher response rates,improved overall survival(OS),and increased tolerability compared with conventional cytotoxic chemotherapy.These benefits may increase the utility of immunotherapy and its combinational use with chemotherapy in the neoadjuvant treatment of patients with NSCLC.Early findings from various ongoing clinical trials suggest that neoadjuvant ICIs alone or combined with chemotherapy may significantly reduce systemic recurrence and improve long-term OS or cure rates in resectable NSCLC.Here we further summarize the safety and efficacy of various neoadjuvant treatment regimens including immunotherapy from ongoing clinical trials and elaborate the role of neoadjuvant immunotherapy in patients with resectable NSCLC.In addition,we discuss several unresolved challenges,including the evaluations to assess neoadjuvant immunotherapy response,the role of adjuvant treatment after neoadjuvant immunotherapy,the efficacy of treatment for oncogenic-addicted tumors,and predictive biomarkers.We also provide our perspective on ways to overcome current obstacles and establish neoadjuvant immunotherapy as a standard of care. 展开更多
