Abstract

CIC-rearranged sarcoma is a rare, aggressive tumor entity with a dismal outcome. We describe a patient with a history of B-cell acute lymphoblastic leukemia (B-ALL), presenting to our hospital with seizures and left-sided upper limb weakness. Brain imaging revealed a localized right frontal mass, which was surgically resected. Initial pathological analyses suggested a secondary malignant neoplasm, not otherwise specified. However, the tumor's methylome was profiled and analyzed using the DKFZ brain tumor classifier to reach a diagnosis of CIC-rearranged sarcoma, confirmed by FISH study. The patient received the ICE protocol, alongside focal radiotherapy. The patient experienced a local recurrence 14 months post-diagnosis. The brain tumor classifier significantly improved the efficiency of diagnosing this rare tumor in a pediatric patient. However, effective therapeutic regimens for CIC-rearranged sarcomas remain unavailable.

有b细胞ALL病史的原发性颅内cic重排肉瘤1例报告。
cic重排肉瘤是一种罕见的侵袭性肿瘤,预后不佳。我们描述了一个有b细胞急性淋巴细胞白血病(B-ALL)病史的病人,以癫痫发作和左侧上肢无力来我院就诊。脑部成像显示右额部有局部肿块,手术切除。初步病理分析提示继发性恶性肿瘤,另有说明。然而,使用DKFZ脑肿瘤分类器对肿瘤的甲基组进行了分析和分析,得出了cic重排肉瘤的诊断,FISH研究证实了这一点。患者接受ICE方案,同时进行局灶放疗。患者在诊断后14个月局部复发。脑肿瘤分类器显著提高了小儿罕见肿瘤的诊断效率。然而,对于cic重排肉瘤的有效治疗方案仍然缺乏。
