Abstract

We previously reported that there was a subgroup of IDH-mutated astrocytomas harboring only 19q-loss showing oligodendroglioma-like morphology and significantly longer overall survival (OS) compared with 19q-intact astrocytomas. To further explore the biological characteristics of this possible subgroup and obtain insight into the mechanism of their clinical behavior, we compared gene expression pattern between five 19q-loss and five 19q-intact IDH-mutated astrocytomas by microarray analysis. Comparing expression level of each genes between 19q-loss and 19q-intact astrocytomas,136 up-regulated genes and 203 down-regulated genes were extracted. Gene expression patterns of 19q-loss astrocytomas were partially different from that of 19q-intact astrocytomas. More down-regulated genes distributed on 19q and 4p, and more up-regulated genes distributed on 4q. Multiple genes associated with stem cell maintenance were down-regulated in 19q-loss astrocytomas, and genes associated with glioma progression were differentially expressed. Comparing expression patterns among 19q-loss astrocytomas and other IDH-mutant glioma subgroups using TCGA datasets by t-SNE analysis revealed that expression pattern of 19q-loss astrocytomas did not shift to that of oligodendrogliomas with 1p/19q codeletion but were a subgroup in astrocytomas. These results indicated that 19q-loss in astrocytomas was an acquired event different from 1p/19q codeletion in oligodendrogliomas, and better prognosis morphological features in 19q-loss astrocytomas were derived from differentially expressed genes associated with stem cell maintenance and glioma progression.

OBJECTIVE: The factors associated with health-related quality of life in patients with glioma remain unclear; particularly, the impact of symptoms on quality of life has not been studied comprehensively. This study aims to document the quality of life of patients with glioma and clarify the impact of symptoms. METHODS: In this cross-sectional study, participants were recruited from patients at The University of Tokyo Hospital and from patients who were registered at the Japan Brain Tumor Alliance. We included adult patients with World Health Organization grade II-IV glioma and excluded those with disturbances of consciousness or aphasia. We used the European Organization for Research and Treatment of Cancer QLQ-C30 and BN20 to evaluate quality of life and the symptoms. Multiple regression analyses were performed to investigate the impact of symptoms on European Organization for Research and Treatment of Cancer global health status and QLQ-C30 social functioning. In addition, we performed univariate subgroup analyses classified by World Health Organization grade and history of chemotherapy. RESULTS: This study included 76 patients. Seven symptoms occurred in more than 50% of the patients: fatigue, future uncertainty, drowsiness, communication deficit, financial difficulties, motor dysfunction and weakness of legs. Multiple regression analyses showed that insomnia affected their global health status, and appetite loss, financial difficulties and motor dysfunction were significantly related to their social functioning. In subgroup analysis, the number of symptom subscales that were significantly related to global health status and social functioning was larger in World Health Organization grade II patients compared with grade III/IV patients. CONCLUSIONS: In addition to neurological deficits, symptoms were associated with poor quality of life in patients with glioma. This study provided the basis on further investigation of usefulness of symptom evaluation on quality of life improvement.

＜文献概要＞1.はじめに覚醒下腫瘍摘出手術は,脳腫瘍周辺の機能領域に対する損傷を避けつつ,腫瘍を最大限に切除することを目的とした術式で,通常の開頭腫瘍摘出術に比べて腫瘍摘出率,術後後遺症,生命予後の点で優位とされる.言語野近傍の腫瘍に対する覚醒下手術では,術中に患者を覚醒させ,言語タスクを実施する間に患者の脳表に電気刺激を与えてその機能を一時的に低下させ,電気刺激によって誘発または抑制される言語症状から患者の機能領域を同定する(図1).術者はこの皮質マッピングの結果を考慮して腫瘍の切除範囲を決定する.また,言語に関わる神経線維近傍の腫瘍切除術では,脳白質に電気刺激を与えて陽性反応を観察する皮質下マッピングも行われる.本邦では,2012年に日本Awake Surgery学会が世界初の英語版覚醒下手術ガイドラインを,また翌年には日本語版ガイドラインを発表した.さらに,2014年には覚醒下脳手術施設認定制度が始まり,2015年には脳腫瘍覚醒下マッピング加算の算定が可能となった.2016年には全国で105件,2017年には185件の覚醒下腫瘍摘出術が施行され,今後覚醒下手術を行う施設はさらに増えるものと予想される.覚醒下手術は多職種によるチーム医療であり,言語・高次脳機能の専門職として言語聴覚士もその一端を担う.当院においても,2016年より言語聴覚士が覚醒下手術に参加し,術前評価,術中マッピング,術後評価とリハビリテーションを行っている.覚醒下手術は世界的に広く行われているが,各国の覚醒下手術における言語聴覚士の役割を知る機会は少ない.今回,英米の2大学病院に勤務する言語聴覚士とともに,当院を含めた3大学病院の覚醒下手術における言語聴覚士の業務内容を比較し,課題や今後の展望について考察したので報告する.なお,本稿の要旨は,The American Speech-Language-Hearing Association Convention 2019において,各病院の言語聴覚士と共同で発表した.また,言語聴覚士の職名は各国で異なるが(英国:Speech Language Therapist,SLT/米国:Speech Language Pathologist,SLP/日本:Speech Therapist,ST),本稿では便宜上,一律に「言語聴覚士」と記載した.

NCCオンコパネルやFoundationOneといった、多数のがん関連遺伝子の異常を一度に解析できるがん遺伝子パネル検査が日本でも保険診療で行えるようになり、わが国のがんゲノム医療体制は急速に整備されてきた。パネル検査により、脳腫瘍領域でも、治療に有用と思われる多数の遺伝子異常が同定できる。例えばEGFR、IDH、H3F3A、HIST1H3B、BRAF遺伝子、NTRK融合遺伝子などである。これらの遺伝子異常に対応した分子標的薬は、現状ではまだまだ少ない状況である。しかし、NTRK融合遺伝子陽性腫瘍に対するエヌトレクチニブは保険承認され、さらにIDH阻害薬やBRAF阻害薬などの臨床試験も行われており、少しずつではあるが、脳腫瘍領域においてもパネル検査結果に基づく個別化医療が推進されていくことが予想される。(著者抄録)

OBJECTIVE: The MD Anderson Symptom Inventory for Brain Tumor (MDASI-BT) module is a widely used instrument for measuring symptom burden and interference of daily activities in brain tumor patients. This study aims to develop and validate its Japanese version (MDASI-BT-Japanese). METHODS: Following forward and backward translation of the original MDASI-BT into Japanese, understandability and feasibility were assessed by cognitive debriefing. Subsequently, patients with brain tumors were asked to fill out MDASI-BT-Japanese and European Quality of Life-5 Dimensions (EQ-5D). Feasibility, reliability and validity of MDASI-BT-Japanese were assessed. RESULTS: Cognitive debriefing confirmed overall ease of completion and good understandability. The study population composed of 140 patients with brain tumors (most commonly gliomas). The mean symptom severity score and mean interference score were 1.9 ± 1.7 and 2.8 ± 2.7, respectively. The top items included distress and drowsiness for symptom severity and general activity and work for interference. The median time required was 4 minutes (range, 0.5-30), and missing values were seen in 1%. Internal consistency was proven by excellent Cronbach's coefficient alpha (0.94 for symptom severity, 0.92 for interference). Test-retest reliability was assessed with acceptable intra-class correlation coefficient (mean, 0.76). Correlation efficient ranged between 0.7 and 0.9 for convergent validity. Known-group validity was confirmed by significantly different mean symptom severity score and mean interference score among patients with different performance status. As evidence of concurrent validity, MDASI-BT-Japanese correlated with EQ-5D in the hypothesized magnitude and direction. CONCLUSIONS: The newly developed MDASI-BT-Japanese has demonstrated feasibility, reliability and validity in evaluation of clinical benefit in Japanese-speaking brain tumor patients.

BACKGROUND: Primary central nervous system (CNS) anaplastic large cell lymphoma (ALCL) is an uncommon type of brain tumor, usually treated with a regimen that includes high-dose methotrexate (MTX). Only a few cases of primary CNS anaplastic lymphoma kinase (ALK)-positive ALCL have been reported so far, with no reported cases of a small cell variant. CASE DESCRIPTION: A 26-year-old man presenting with headache and visual field impairment was found to have a supratentorial mass mimicking meningioma. Craniotomy was performed for tumor resection, and postoperative histologic examination revealed atypical cells that were nonenlarged lymphocytes with irregularly shaped and enlarged nuclei; these cells were cluster of differentiation 30 and ALK-positive, leading to the diagnosis of a small cell variant of ALK-positive ALCL. In this case, the tumor exhibited an aggressive behavior with MTX resistance with metastases in the pelvis but responded well to cytarabine and etoposide (CYVE). CONCLUSIONS: In general, CNS ALK-positive ALCL responds well to MTX, but small cell variants show aggressive behavior and may be resistant to MTX. For small cell variants of ALCL that are resistant to MTX therapy, as in this case, CYVE therapy may be an effective treatment.

Glioma is characterized by a high heterogeneity in the brain tumor. Abundant tumor-associated macrophages (TAMs) exist as neoplastic tissues, implicating tumor plasticity and thus leading to therapeutic challenges. Vascular adhesion protein (VAP-1) potentially serves as a mediator for TAM immunity in tumor milieu. We previously demonstrated that VAP-1 could contribute to tumor malignancy, but its characteristics in TAM immunity of glioma progression are still unclear. This study explored the association of VAP-1 expression with TAM distribution as well as the resulting clinical significance and prognostic value in human gliomas. An in-depth analysis of AOC3 (VAP-1) gene expression was performed using 695 glioma samples derived from the cancer genome atlas (TCGA)-lower grade glioma and glioblastoma (GBMLGG) cohort. Bioinformatic analysis confirmed that VAP-1 expression is associated with poor prognosis of glioma patients (p = 0.0283). VAP-1 and TAM biomarkers (CD68, iNOS, and CD163) were evaluated by immunohistochemistry in 108 gliomas from Kaohsiung Medical University Hospital. VAP-1+ was expressed in 56 (51.85%) cases and this phenotype revealed a significant association with overall survival in Kaplan-Meier analysis (p < 0.0001). Immunohistochemical double staining showed that VAP-1 immunoreactivity was present around CD163+ M2 infiltration location, including aggressive lesions and neighboring neovasculature. We demonstrated that high VAP-1 expression levels positively correlated with CD163+ M2 activation and coexpression of these two proteins was associated with worse survival in gliomas (p < 0.0001). Multivariate analysis indicated that VAP-1 alone and co-expressed with CD163 were the significantly independent indicators (both p < 0.0001). Furthermore, VAP-1/CD163 coexpression exhibited excellent diagnostic accuracy in gliomas (AUC = 0.8008). In conclusion, VAP-1 and TAM CD163 M2 coexpression was found in glioma tissues belonging to a highly malignant subgroup that was associated with poor prognosis. These results implied VAP-1 abundance is closely linked to alternative M2 activation during glioma progression. From the aforementioned data, a reasonable inference is that VAP-1 combined with targeting M2 immunity might be an effective therapeutic target for human gliomas.
