[Composite lymphoma consisting of adult T-cell leukemia-lymphoma and diffuse large B-cell lymphoma].

A 68-year-old man was admitted to our hospital because of left back pain and systemic lymphadenopathy with hypercalcemia. Serum anti-HTLV-1 antibody was positive. Left cervical lymph node (LN) biopsy revealed proliferation of medium-sized to large CD4-positive atypical cells with modest infiltration of CD20 and Epstein-Barr virus (EBV)-encoded RNA dual-positive atypical large cells. Monoclonal integration of HTLV-1 proviral DNA, plus clonal rearrangement of the T-cell receptor chain gene and the immunoglobulin heavy chain gene, were detected in the same LN specimen. Composite lymphoma consisting of adult T-cell leukemia/lymphoma (ATL) and EBV positive diffuse large B-cell lymphoma (DLBCL) was diagnosed. He was successfully treated with aggressive chemotherapy including rituximab and attained remission. However, eight months later, he developed right shoulder pain due to multiple bone invasions with bilateral cervical lymphadenopathy. Biopsies of a bone lesion and cervical LN revealed recurrence of ATL alone. The patient died despite salvage chemoradiotherapy. These findings suggest that ATL-related immunodeficiency might induce EBV-associated DLBCL.

Contemporary practice and outcomes of an elderly cohort of Japanese patients with non-ST-elevation acute coronary syndrome in the era of routine early invasive strategy.

BACKGROUND: An early invasive strategy for patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) has been recommended. However, patients at greater risk including the elderly are more often managed conservatively. We aimed to elucidate contemporary practice and outcomes of patients with NSTE-ACS who were referred to our hospital located in Kitakyushu City, one of the most aging metropolises in Japan. METHODS: A total of 270 consecutive NSTE-ACS patients hospitalized between January 2012 and December 2014 were retrospectively studied. RESULTS: Median [interquartile range] age was 73 [64, 80]years. Coronary angiography was performed in 264 (98%) patients. Importantly, 75% and 89% underwent angiography within 24h and 72h after admission, respectively. Revascularization was done in 124 (79%). The all-cause, in-hospital mortality was 3.7% and was higher in patients aged ≥80years (8.5% vs. 2.0% in those aged <80years, p<0.0001). No patient developed major bleeding or stroke during hospitalization. Killip class IV at presentation (odds ratio [OR] 8.77, 95% confidence intervals [CI] 1.64-47.6) and left main trunk disease (OR 7.58, 95% CI 1.28-45.5) were independently associated with in-hospital death. These two variables and a high (≥140) GRACE score were associated with a higher 1-year mortality by Kaplan-Meier survival analysis (p<0.0001). CONCLUSIONS: An early invasive strategy was safely done in an elderly cohort of Japanese patients with NSTE-ACS. In addition to early invasive approach, a further therapeutic strategy, most probably targeting a shock status, is needed to improve both short- and long-term survival.
