Next-generation sequencing-based comprehensive genome profiling (CGP) testing, OncoGuide NCC Oncopanel System, and FoundationOne CDx Cancer Genomic Profile have been covered by the Japanese national health insurance system since June 2019. Because CGP was initially developed to enroll patients into an early-phase clinical trial for solid tumors, its approved indications have been limited to patients who have completed the standard chemotherapy treatment. Approximately 14,000 cases have been registered with the Center for Cancer Genomics and Advanced Therapeutics as of March 2021.

The present report describes the case of a 71-year-old female patient who underwent surgery for thyroid carcinoma involving the larynx.

Here, we report novel derivation of a male canine iPSC line OF35Y-iPS, which showed standard characteristics of pluripotency such as a strong gene expression profile of pluripotency markers, differentiation potential into all three germ layers, and normal karyotype (78XY). Furthermore, we demonstrated targeted integration of 2A-EGFP into the canine NANOS3 locus.
View Article and Find Full Text PDFImmune thrombotic thrombocytopenic purpura (iTTP) is caused by ADAMTS13 deficiency due to anti-ADAMTS13 autoantibodies. Rituximab, an anti-CD20 monoclonal antibody, is often used to suppress these autoantibodies. This retrospective study, conducted in an iTTP cohort in Japan, evaluated the long-term efficacy of rituximab as off-label treatment for refractory or relapsed cases.

Introduction of a rapid assay for ADAMTS13 activity should reduce the time to definite diagnosis of aTTP, reduce the amount of inappropriately transfused PLT concentrates, and improve mortality and morbidity.
Study Design And Methods: We selected 265 aTTP patients with severe ADAMTS13 deficiency.
We report the case of a 66-year-old man with primary diffuse large B-cell lymphoma of the prostate presenting with urinary retention and dyschezia as first manifestation. Although a colostomy was needed due to rectal obstruction, rituximab-combined chemotherapy resulted in complete remission. He underwent stoma closure safely and has remained in complete remission for over 3years.

Bone marrow examination showed hypercellular bone marrow accompanied by dysplasia, and the karyotype of his bone marrow cells was 46,XY, der(5;12)(q10;q10), +mar,inc[3]/46,XY[12]. A diagnosis of myelodysplastic syndrome, unclassifiable, was made.

Intensified chemotherapy followed by autologous peripheral blood stem cell transplantation resulted in long-term complete remission for over 5 years. As the most frequent sites of B-lymphoblastic lymphoma involvement are the skin, soft tissue, bone, and lymph nodes, reports of cases harboring cardiac involvement are relatively few.

About 5-10% of CML patients have complex variant translocations involving a third chromosome in addition to chromosomes 9 and 22. Herein, we describe a CML-chronic phase male with a complex translocation involving chromosome 16, t(9;22;16)(q34;q11;q24).
