A total of 82 pathologically confirmed, CD20-positive, diffuse large B-cell lymphoma patients aged 71 years or older who underwent therapeutic intervention in the Tohoku and Niigata area in Japan were retrospectively reviewed. A univariate analysis was performed by the log-rank test using the Kaplan-Meier method. A Cox proportional hazards model was used for multivariate analysis of risk factors. Of the 82 patients, 39 were male and 43 were female, and their median age at onset was 75 years. At the end of the study, there were 34 relapse-free patients (41.5%), 48 relapse cases (58.5%), median progression-free survival was 18 months, and median overall survival (OS) was 26 months; there were 41 deaths and 41 survivors. Multivariate analysis of median OS showed that Karnofsky Performance Status less than 60% 3 months after treatment (p = 0.022, hazard ratio (HR) = 2.591) was the clinical risk factor, and double expressor lymphoma (p = 0.004, HR = 3.163), expression of programmed death-ligand 1 in tumor infiltrating lymphocytes or tumor-associated macrophages (p < 0.001, HR = 5.455), and Epstein-Barr virus infection (p = 0.031, HR = 5.304) were the pathological risk factors.","PeriodicalId":9226,"journal":{"name":"Brain Tumor Pathology","volume":" ","pages":"139-150"},"PeriodicalIF":3.3,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40310187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the age of 42, the patient underwent initial resection of a right temporal oligodendroglioma IDH mutated 1p/19q co-deleted WHO Grade II followed by adjuvant radiochemotherapy with temozolomide. 15 months after initial diagnosis, the patient showed right hemispheric tumor progression and an additional new left frontal contrast enhancement in the subsequent imaging. A re-resection of the right-sided tumor and resection of the left frontal tumor were conducted. Neuropathological work-up showed recurrence of the right-sided oligodendroglioma with features of an anaplastic oligodendroglioma WHO Grade III, but a glioblastoma WHO grade IV for the left frontal lesion. In depth molecular profiling revealed two independent brain tumors with distinct molecular profiles of anaplastic oligodendroglioma IDH mutated 1p/19q co-deleted WHO Grade III and glioblastoma IDH wildtype WHO grade IV. This unique and rare case of a patient with two independent brain tumors revealed by in-depth molecular work-up and epigenomic profiling emphasizes the importance of integrated work-up of brain tumors including methylome profiling for advanced patient care.","PeriodicalId":9226,"journal":{"name":"Brain Tumor Pathology","volume":"39 2","pages":"111-119"},"PeriodicalIF":3.3,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9090705/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39689454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
