Glioblastoma is profoundly heterogeneous in regional microstructure and vasculature. Characterizing the spatial heterogeneity of glioblastoma could lead to more precise treatment. With unsupervised learning techniques, glioblastoma MRI-derived radiomic features have been widely utilized for tumor sub-region segmentation and survival prediction. However, the reliability of algorithm outcomes is often challenged by both ambiguous intermediate process and instability introduced by the randomness of clustering algorithms, especially for data from heterogeneous patients.
In this paper, we propose an adaptive unsupervised learning approach for efficient MRI intra-tumor partitioning and glioblastoma survival prediction. A novel and problem-specific Feature-enhanced Auto-Encoder (FAE) is developed to enhance the representation of pairwise clinical modalities and therefore improve clustering stability of unsupervised learning algorithms such as K-means. Moreover, the entire process is modelled by the Bayesian optimization (BO) technique with a custom loss function that the hyper-parameters can be adaptively optimized in a reasonably few steps. The results demonstrate that the proposed approach can produce robust and clinically relevant MRI sub-regions and statistically significant survival predictions.

胶质母细胞瘤(GBM)管理中的一个重大挑战是在常规治疗后的常规成像中识别肿瘤复发的假进展(PsP),这是一种良性辐射诱导效应。先前的研究已经将肿瘤叶的存在和偏侧性与GBM结果联系起来,表明GBM中的疾病病因和进展可能受到肿瘤位置的影响。因此,在这项可行性研究中,我们试图研究以下问题:初治MRI上的肿瘤位置是否可以提供有关患者发生假性进展与肿瘤复发可能性的早期线索?在这项研究中,分析了74例治疗前胶质母细胞瘤MRI扫描,其中PsP(33例)和肿瘤复发(41例)。首先,Gd-T1 w MRI增强病灶和T2 w/FLAIR病灶周围高信号由专家分割,然后配准到脑图谱。使用来自两种表型的患者,我们通过量化增强病变和病变周围高信号的发生频率,通过对整个人群的体素强度进行平均来构建两个图谱。然后进行差异参与分析,以计算各图谱之间的体素显着差异(p值<0.05)。最后将统计学上显著的聚类映射到结构图谱中,以提供其位置的解剖定位。我们的研究结果表明,肿瘤复发的患者表现出突出的顶叶的初始肿瘤,而PsP患者表现出多灶性分布的初始肿瘤在额叶和颞叶,颞叶和壳核。这些初步结果表明,治疗前病变向大脑某些解剖区域的偏侧化可以提供有关评估MRI扫描上肿瘤复发发生假性进展的可能性的早期线索。
