Women with hereditary breast and ovarian cancer (HBOC) syndrome represent a unique group who are diagnosed at a younger age and result in an increased lifetime risk for developing breast, ovarian and other cancers. This review integrates recent progress and insights into the molecular basis that underlie the HBOC syndrome. A review of English language(More)
OBJECTIVE In the present study, we evaluated changes in CA-125 cut-off values predictive of complete interval debulking surgery (IDS) after neoadjuvant chemotherapy (NAC) using receiver operating characteristic (ROC) analysis. METHODS This retrospective single-institution study included patients with International Federation of Gynecology and Obstetrics(More)
Primary breast diffuse large B-cell lymphoma has a poor prognosis relative to other extranodal diffuse large B-cell lymphoma. Recently, diffuse large B-cell lymphoma has been subclassified as germinal center B-cell-like and nongerminal center B-cell types using tissue microarrays. The 5-year overall survival rate of the germinal center B-cell group is(More)
Endometriosis-associated ovarian cancers demonstrate substantial morphological and genetic diversity. The transcription factor, hepatocyte nuclear factor (HNF)-1β, may be one of several key genes involved in the identity of ovarian clear cell carcinoma (CCC). The present study reviews a considerably expanded set of HNF-1β-associated genes and proteins that(More)
An antiemetic regimen for patients taking paclitaxel and carboplatin (TC) includes dexamethasone (20 mg) to protect against hypersensitivity. Chemotherapy-induced nausea and vomiting (CINV), however, is difficult to adequately control in patients receiving TC. In the present study, we retrospectively investigated risk factors for CINV in patients receiving(More)
CD10, a proteolytic enzyme seen in germinal center cells and in the majority of follicular lymphomas, is occasionally expressed in diffuse large B-cell lymphomas (DLBCL). To clarify the origin and cellular characteristics of CD10-positive DLBCL, we analyzed 36 de novo cases of DLBCL for somatic mutations of the immunoglobulin heavy chain variable region(More)
The characteristics of de novo diffuse large B-cell lymphoma (DLBCL) with translocation of c-myc and immunoglobulin (Ig) genes (c-myc/Ig DLBCL), were investigated in 13 cases of c-myc/Ig DLBCL. Immunohistochemistry revealed five cases were positive for CD10 and BCL6 expression (CD10(+)/BCL6(+)), five cases of CD10(-)/BCL6(+)/MUM1(-), one case of(More)
Mullerian adenosarcoma (MA) is a rare tumor variant with low malignancy potential and is reported to account for 8% of all uterine sarcomas. Cervical MAs are reported to occur in relatively younger patients with the mean age of 27 years, while those in the uterine corpus generally present in postmenopausal women. Due to the rarity of cervical MAs, optimal(More)
We examined nucleotide sequences of Epstein-Barr virus (EBV)-positive Hodgkin/Reed-Sternberg (HRS)-like B cells in a case of diffuse large B-cell lymphoma (DLBCL) and a case of adult T-cell lymphoma (ATL) for single-cell polymerase chain reaction of the immunoglobulin heavy-chain gene variable region (VH gene). HRS-like B cells were scattered in the area(More)
CD5+ diffuse large B-cell lymphoma (DLBCL) has recently been identified as a subgroup with different clinical characteristics from CD5- DLBCL and as having a poorer outcome than CD5- DLBCL. Data regarding differences in gene alteration between CD5+ and CD5- DLBCL have accumulated. In this article, we report an analysis of the immunoglobulin heavy-chain gene(More)
