| 1 | Coupling radiomics analysis of CT image with diversification of tumor ecosystem: A new insight to overall survival in stage Ⅰ-Ⅲ colorectal cancer显示文摘Objective: This study aimed to establish a method to predict the overall survival(OS) of patients with stage Ⅰ-Ⅲ colorectal cancer(CRC) through coupling radiomics analysis of CT images with the measurement of tumor ecosystem diversification.Methods: We retrospectively identified 161 consecutive patients with stage Ⅰ-Ⅲ CRC who had underwent radical resection as a training cohort. A total of 248 patients were recruited for temporary independent validation as external validation cohort 1, with 103 patients from an external institute as the external validation cohort 2. CT image features to describe tumor spatial heterogeneity leveraging the measurement of diversification of tumor ecosystem, were extracted to build a marker, termed the EcoRad signature. Multivariate Cox regression was used to assess the EcoRad signature, with a prediction model constructed to demonstrate its incremental value to the traditional staging system for OS prediction.Results: The EcoRad signature was significantly associated with OS in the training cohort [hazard ratio(HR)=6.670;95% confidence interval(95% CI): 3.433-12.956;P<0.001), external validation cohort 1(HR=2.866;95% CI: 1.646-4.990;P<0.001) and external validation cohort 2(HR=3.342;95% CI: 1.289-8.663;P=0.002).Incorporating the EcoRad signature into the prediction model presented a higher prediction ability(P<0.001) with respect to the C-index(0.813, 95% CI: 0.804-0.822 in the training cohort;0.758, 95% CI: 0.751-0.765 in the external validation cohort 1;and 0.746, 95% CI: 0.722-0.770 in external validation cohort 2), compared with the reference model that only incorporated tumor, node, metastasis(TNM) system, as well as a better calibration,improved reclassification and superior clinical usefulness.Conclusions: This study establishes a method to measure the spatial heterogeneity of CRC through coupling radiomics analysis with measurement of diversification of the tumor ecosystem, and suggests that this approach could effectively predict OS and could be used as a supplement for risk stratification among stage Ⅰ-Ⅲ CRC patients. | Yanqi Huang Lan He Zhenhui Li Xin Chen Chu Han Ke Zhao Yuan Zhang Jinrong Qu Yun Mao Changhong Liang Zaiyi Liu | 2022 | Chinese Journal of Cancer Research2022，34，1： | 2 |
| 2 | Mesoporous PtPd nanoparticles for ligand-mediated and imaging-guided chemo-photothermal therapy of breast cancer显示文摘The synergistic therapy of chemotherapy and photothermal therapy(PTT)has been reported as a promising antitumor strategy.To achieve effective combination therapy,developing more suitable candidate nanomaterials with optimal photothermal property and high chemical drug loading capacity is very necessary.Herein,a bimetallic PtPd nanoparticle was synthesized with the merits of excellent photothermal effect and mesoporous structure for doxorubicin(DOX)loading.We further designed PtPd-ethylene glycol(PEG)-folic acid(FA)-doxorubicin(DOX)nanoparticle for chemo-photothermal therapy of MCF-7 tumor with folic acid engineering to achieve active targeting.Moreover,excellent photoacoustic(PA)imaging of PtPd-PEG-FA-DOX nanoparticles facilitated the precise in vivo tracking and further evaluation of nanoparticles’targeting effect.The in vitro and in vivo results both demonstrated PtPd-PEG-FA-DOX nanoparticles serve as a safe and promising system for effective treatment of MCF-7 tumor. | Yanpeng Jia Yang Song Ying Qu Jinrong Peng Kun Shi Dan Du He Li Yuehe Lin Zhiyong Qian | 2020 | Nano Research2020，13，6： | 2 |
