ABSTRACT
Objective@#To study clinicopathologic features, prognosis and differential diagnoses of primary mucosal CD30-positive T-cell lymphoproliferative disorders of the head and neck(mCD30+ TLPD-head and neck).@*Methods@#Three cases of mCD30+ TLPD-head and neck were collected from January 2014 to April 2017 at Sun Yat-Sen University Foshan Hospital. A literature review of mCD30+ TLPD of head and neck was provided.@*Results@#All three cases presented with either bulging/exophytic nodule or mucosal ulcer/erosion. Morphologically, the tumor consisted of diffuse proliferation of uniform, large atypical mononuclear lymphoid cells that showed irregular or polymorphic nuclei with small nucleoli, and abundant pale or amphophilic cytoplasm. Hallmark cells with eccentric, horseshoe, kidney-like, or doughnut-shaped nuclei were present. While mitotic figures were present, no tumor necrosis was found. Eosinophilc infiltration was obvious in the background. The atypical large lymphoid cells had a immunophenotype of CD30+ /CD3+ /CD4+ /CD56- along with positive cytotoxic molecule. While being negative for EBER/ALK/CD20/CD8, TCR rearrangement was found in 2 out of 3 cases. Three patients were cured after excision without relapse and metastasis.The two patients with TCR rearrangement didn′t show aggressive clinical course.@*Conclusions@#mCD30+ TLPD-head and neck is a rare benign lymphoproliferative disorder with spontaneous regression. It should be differentiated from cutaneous CD30+ anaplstic large cell lymphoma, lymphomatoid papulosis, and EBV-related mucocutaneous ulcer. Correct recognition of mCD30+ TLPD of head and neck is important to avoid overtreatment.
ABSTRACT
Background and purpose:Neuropilin-1 (NRP1), a vascular endothelial growth factor (VEGF) receptor, plays an important role in tumor angiogenesis and tumor cell migration. The purpose of this study was to de-termine the correlation between NRP1 expression and sensitivity to ifrst-line platinum-based chemotherapy in patients with advanced non-small cell lung cancer (NSCLC), and between NRP1 expression and survival.Methods:NRP1 ex-pression in tumor tissues of 104 advanced NSCLC patients treated with ifrst-line platinum-based regimen was detected by immunohistochemisty.A chi-square test and logistic regression model were used to analyze the relationship between NRP1 expression and the chemotherapy response rate. Kaplan-Meier and Cox proportional hazard regression models were used to analyze the effect of NRP1 expression on patient survival.Results:Among the 104 patients, 56 (53.8%) had high expression of NRP1. High expression of NRP1 was not related to age, gender, histological type, degree of differentiation, performance status, and chemotherapy regimen. The chemotherapy response rate was significantly higher in patients with low NRP1 expression than in patients with high expression (43.8% vs23.2%,P=0.026). The low NRP1 expression was signiifcantly associated with longer progression-free survival (4.6 monthsvs3.0 months, P=0.001 for log-rank test,χ2=11.273) and overall survival (11.5 monthsvs9.2 months,P=0.000 for log-rank test,χ2=14.392) as compared with high NRP1 expression. Multivariate analysis showed that high expression of NRP1 was an independent predictor for the chemotherapy response rate and overall survival in patients with advanced NSCLC.Conclusion:NRP1 expression is associated with response rate and survival in advanced NSCLC patients treated with ifrst-line plati-num-based chemotherapy. NRP1 expression may be a potential biomarker for predicting chemosensitivity and prognosis in patients with advanced NSCLC.
ABSTRACT
Purpose To analyze and summarize morphological characteristics, the immune phenotype, diagnosis and differential diag-nosis, clinical features and prognosis of epithelioid angiomyolipomas retrospectively, to deepen understanding of EAML and improve the diagnostic accuracy. Methods The pathological morphology was observed and immunohistochemistry of phenotypic characteristics were analyzed in 7 cases of epithelioid angiomyolipomas. Results Seven cases of epithelioid angiomyolipomas had similar morphology:larger tumor cells, ovoid, fusiform or polygonal, with abundant and eosinophilic cytoplasm, a big nucleus of different size with obvious nucleoli, polynuclear and gaint tumor cells, with a few mitotic figures. The tumor cells arranged in nests or sheets, cuff-shaped around the blood vessels. Immunohistochemistry showed that the tumor cells were positive for HMB-45, Melan-A, vimentin and SMA, but negative for EMA, CK, and CD10. All of them underwent radical surgery or surgical resection, and were followed up for 3~56 months after operation. 6 cases were alive, without recurrence and metastasis, while 1 case died of gastrointestinal stromal sarcomas 3 months later. Conclusion Epithelioid angiomyolipomas belong to mesenchymal tumors with malignant potential, pathological morphology would be easily misdiagnosed as malignant tumors. Immunohistochemistry plays an important role in the differential diagnosis. Surgical treatment is the main method at present, with possibility of recurrence or metastasis.
ABSTRACT
Objective To investigate the clinicopathological features of human immunodeficiency virus (HIV) negative plasmablastic lymphoma (PBL) with no-immunosuppression,so as to accelerate the understanding for this group of disease.Methods The histological features of 6 HIV-PBL patients with no-immunodeficiency were retrospectively analyzed.Epstein-Barr virus (EBV) status was detected by in situ hybridization.Then,immunohistochemistry and fluorescence in situ hybridization (FISH) method were used to determine the immunophenotype,latent status of EBV and MYC translocation in PBL,respectively.Results HIV-PBL showed monotonous proliferation of plasmablastoid or immunoblast-like cells.Giant cells and necrosis could be observed,with less reactive cells in the background and higher mitoses.All the cases had EBV infection and type Ⅰ latency status of EBV (LMP1-/EBNA2-),and expressed terminal B-cell differentiation immunophenotype (CD20-/CD3-/CD138+/Kappa or Lambda+).Six HIV-PBL patients were elderly (median age was 69.5 years old),had equal incidence of PBL between male and female and showed high frequency of involvement of extranodal and extraoral lesion sites (6 cases and 5 cases,respectively).Median sutvival was 25.5 months.In addition,3 HIV-PBL patients had IGH/MYC translocations.Conclusions HIV-PBL is a new entity with unique clinical features including no-HIV infection,elderly,EBV positivity,and more involvement in extranodal and extraoral sites.HIV-PBL should be distinguished from HIV+ PBL.
ABSTRACT
OBJECTIVE@#To estimate the predictable value of histopathologic parameters in chronic rhinosinusitis with nasal polyps (CRSwNP) after endoscopic sinus surgery(ESS).@*METHOD@#Symptomatology was rated in 53 patients 12 to 24 months after ESS. Specimens taken during the surgical procedure were examined and scored for eosinophils, goblet cells, lymphocytes, subepithelial thickening, subepithelial edema and submucous gland formation. The correlation between histopathologic parameters and postoperative symptoms was then evaluated.@*RESULT@#The most common symptome after ESS were nasal obsruction, nasal secretion, discharge and sneezing. The correlation between goblet cells and sneezing, discharge, submucous gland formation and headache, subepithelial edema and postnasal secretion was significant (P < 0.05).@*CONCLUSION@#Certain histopathologic parameters in CRSwNP are predictive of favorable response to ESS.

ABSTRACT
AIM To study the effects of growth inhibition of different concentrations of diallyl trisulfide(DATS) on gastric cancer MGC 803 cell line in vitro. METHODS The influence of different concentrations of DATS were examined by MTT assay, clonal formation rates and cell growth curve. RESULTS Suppression and decrease of MGC 803 cell proliferation was found after treatment by DATS in vitro. The inhibitory rates on MGC 803 cell growth of different concentration of DATS,4, 8, 12, 16 and 24 mg?L -1 , were 26%,46%,65%,76% and 89% respectively, and its half inhibitory concentration (IC 50 ) was 8 2 mg?L -1 . The clonal formation rates and clonal formation relative counts of 8, 12, 16 and 24 mg?L -1 were 32 4% and 58 7%,24 8% and 42 5%,19 0% and 33 5%?8 8% and 15 1% respectively.There was significant correlation between dose and effect in all, and the cell growth culve became lower and flatter when concentration of DATS increase gradually. CONCLUSION The effect of growth inhibition of DATS for gastric cancer MGC 803 cell in vitro is remarkable.
