Background and purpose: Herpesvirus-associated ubiquitin-specific protease (HAUSP) is a new deubiquitinating enzyme that was recently discovered. It has been demonstrated that HAUSP could deubiquitinate p53 both in vitro and in vivo. These results suggested that HAUSP might act as a tumor suppressor through the stabilization of p53 protein. The aim of this study was to investigate the expression of HAUSP in breast carcinoma, and its association with p53 protein as well as their relationship to prognosis. Methods: The expression of HAUSP mRNA was detected by real-time PCR. HAUSP protein and p53 protein were detected by immunohistochemistry with EnVision system in breast carcinoma tissues and noncancerous tissues. The relationship between their expressions and clinical pathological parameters were analyzed. Results: The expression of HAUSP mRNA was significantly lower in breast cancer tissue than noncancerous tissue (1.85±0.04 vs. 2.74±0.03, P<0.01). The positive rates of HAUSP protein were significantly lower in breast cancer tissue in noncancerous tissue (59.4% vs. 75.0%, P<0.01), and expression of HAUSP protein had no significant correlation with the clinical pathological parameters. There was no significant correlation between HAUSP and p53 protein (P>0.05). The expression of HAUSP mRNA was positively associated with that of HAUSP protein (P<0.01). There was no significant correlation between HAUSP and p53 protein. DFS of patients with both HAUSP positive and p53 negative was significant higher than the controls (P<0.01). Conclusion: Down-regulation of HAUSP protein and HAUSP mRNA in breast carcinoma indicated that HAUSP gene might correlated to tumor carcinogenesis. In addition, the simultaneous evaluation of both HAUSP expression and p53 expression status may be helpful to evaluate the prognosis of breast cancer patients.

Objective To investigate the histological features and prognostic factors of angioimmunoblastic T?cell lymphoma (AITL). Methods The pathological data of 62 patients with AITL with complete follow?up information were retrospectively collected and analyzed from Changhai Hospital during September 2012 and September 2017. Histological and immunohistochemical (IHC) examination, in situ hybridization (ISH), and single nucleotide polymorphisms (SNP) gene mutation analysis were done. Subgroup evaluation with histology, IHC, ISH, SNP gene mutation, and association with clinical progression were performed. Results The cohort included 62 cases of AITL, including 46 males and 16 females patients, with a median age of 64 years. Follicular dendritic cells (FDC) area showed significantly expansion (≥30%) in 40 cases; increased plasma cells (≥10%) was seen in 37 cases; B cells were distributed around blood vessels in 37 cases; and increased p53 mutation positive cells (≥40%) were seen in 39 cases; high Ki?67 index (≥40%) was seen in 39 cases; RHOA mutation was seen in 19 cases; TET2 mutation was seen in 9 cases. Overall survival analysis showed these factors were significantly correlated with tumor prognosis (P<0.05). Multivariate analysis showed that CD38 positive cells<10%, Ki?67≥40%, RHOA and TET2 mutations were risk factors associated with overall survival. Conclusions AITL could be divided into two different prognostic groups, low?grade and high?grade, with statistically significance outcome, based on the FDC area expansion, degree of plasma cell proliferation, B cells distribution pattern combined with gene mutations and clinical progression. Low?grade malignant group progresses slowly, and high?grade malignant group is highly invasive.

Objective:To evaluate the clinicopathologic characteristics and outcomes of HIV-negative plasmablastic lymphoma (PBL) .Methods:Medical records of 15 patients diagnosed with HIV-negative PBL in Changhai Hospital between January 2013 and August 2019 were reviewed, and clinicopathologic characteristics and outcomes were analyzed.Results:Median age was 59 years (range: 17-69) . All patients had extranodal involvement. According to the Cotswolds-modified Ann Arbor staging system, 1 (6.7%) , 2 (13.3%) , 3 (20.0%) , and 9 (60.0%) patients were classified as at Ⅰ,Ⅱ,Ⅲ and Ⅳ, respectively. Plasmablast and immunoblast proliferations were typical manifestations of PBL. Immunohistochemical staining showed tumor cells were diffusely positive for plasma cell markers CD38, CD138, and Mum-1, while negative for B cell markers CD20, CD10, PAX-5, and BCL-6. Median Ki-67 index was 80% (70%-90%) . Epstein-Barr virus-encoded RNA (EBER) expression was detected in 3 patients, and 1 of them was positive. All patients received chemotherapy, 80% combined with bortezomib as the first line, and responses were observed in 8 patients (6 complete and 2 partial responses) . Median progression-free survival (PFS) and overall survival (OS) were 6.8 (95% CI 2.5-11.1) months and 17.9 (95% CI 5.6-30.2) months, the 3-year PFS and OS rates were 21.2% (95% CI 1.4%-56.8%) and 38.5% (95% CI 12.0%-65.0%) , respectively. Conclusion:HIV-negative PBL with high invasiveness is extremely prone to extranodal involvement and most patients were at the advanced stage. Patients receiving an intensive therapy combined with bortezomib and bridged autologous stem cell transplantation may improve long-time survival.
