Objective To analyze the clinicopathologic features of primary cutaneous CD30 positive lymphoproliferative disorders. Methods A clinical, pathological and immunohistochemical analysis was carried out in 4 cases of lymphomatoid papulosis and 5 cases of primary cutaneous anaplastic large cell lymphoma. Results Lymphomatoid papulosis was divided into 3 subtypes, A, B and C. The lymphomatoid papulosis of subtype A was pathologically characterized by pleomorphic anaplastic large cells or Steinberg-reed cells scattered or patchly distributed among many inflammatory cells; subtype B showed pathological changes characteristic of granuloma fungoides, and manifested as a broad infiltration zone of lymphocytes in dermis with scattered small- to middle-sized atypical gyrus-like lymphocytes; subtype C was characterized by a diffuse distribution of anaplastic large cells and could clinically subside spontaneously. Primary cutaneous anaplastic large cell lymphoma clinically manifested as subcutaneous nodules or papules, and was pathologically characterized by large, pleomorphic, round or ellipse cells with plentiful, eosinophilic or bicolor cytoplasm, large nuclei and obvious nucleoli. The neoplastic cells characteristically expressed CD30 antigen in both lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma, and all the cases showed a favorable prognosis.Conclusions Primary cutaneous CD30 positive lymphoproliferative disorders are a spectrum of cutaneous T cell lymphoma with favorable prognosis, and a synthetic analysis of clinical, histopathological and immunohistochemical findings is beneficial to the diagnosis of these entities.

Objective:To evaluate prognosis factors of primary vaginal cancer. Methods:Data of 80 patients who were hospitalized in the Department of Gynecology and Oncology of Guangxi Tumor Hospital from January 2003 to January 2015 were retrospectively ana-lyzed. All the patients were divided into radiotherapy group (n=49) and surpery group (n=31). Based on radiation mode, the patients with radiotherapy were divided into two-dimensional radiotherapy group (n=29) and three-dimensional radiotherapy (3DRT) group (n=20). Prognosis and complications between two subgroups were compared. Surgical patients were divided into laparoscopic surgery group (n=16) and laparotomy surgery group (n=15) with comparing therapeutic feasibility of video-laparoscopic operation and laparot-omy for primary vaginal carcinoma treatment. Results:Univariate analysis showed that FIGO stage, pathology, tumor size, and extent of vaginal mass involvement were related to prognosis (P<0.05). Multivariate analysis showed that FIGO stage and pathology were in-dependent prognostic factors. Statistical differences of 5-year survival were significant between 2DRT (20.9%) and 3DRT (58.6%) groups (P=0.022). Incidences of urinary tract (14/29, 48.27%) and gastrointestinal symptoms (15/29, 51.72%) in 2DRT group and in 3DRT (3/20,15%;4/20,20%) are different significantly (P<0.05). Hospitalization days of laparotomy surgery group (57.00 ± 41.75) were significantly longer than that of laparoscopic surgery group (29.56 ± 7.30) (P=0.024). Conclusion: Applying laparoscopic surgery and 3DRT improved quality of life without decreasing survival rate of patients with vaginal cancer.

Objective To investigate the relationship between multidrug resistance of X-ray irradiated human nasopharyngeal squanous carcinoma cell line CNE1 and platelet endothelial cell adhesion molecule-1 (PECMA-1)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT)/Bcl-2 signaling pathway.Methods ①The CNE1 cells were cultured in incubator.Exponentially growing CNE1 cells were exposed to 50 Gy ionizing radiation administered in 25 fractions,2 Gy per fraction,once every two days,and the CNE1/R cells were collected.②CNE1/R cells were cultured for 24 h,and divided into three groups:the control group,experimental group one (CNE1/R cells were processed through 1 ∶ 600 PECAM-1 antibody for 24 h) and experimental group two (CNE1/R cells were processed through 10 μmol/L PI3K inhibitor LY294002 for 24 h).③The half maximal inhibitory concentration (IC50) values of the control group and two experimental groups of CNE1/R cells were detected by methyl thiazolyl tetrazolium (MTT).④The mRNA expressions of PI3K and Bcl-2 in the control group and experimental group one were measured by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR).⑤The mRNA expressions of AKT and Bcl-2 in the control group and experimental group two were measured by semi-quantitative RT-PCR.Results ①The IC50 of the control group,experimental group one and two were (2.99 ± 0.02) μg/ml,(1.50 ± 0.03) μg/ml and (1.60 ±0.05)μg/ml,and the difference among the three groups was statiatically signficant (F =4 381.263,P =0.000).The IC50 of the two experimental groups were obviously lower than that of the control group (t =116.885,P =0.000;t =73.006,P =0.000).②The semi-quantitative values of PI3K in the control group and experimental group one were 1.66 ±0.01 and 0.90 ±0.05 (t =50.394,P =0.000),and the semi-quantitative values of Bcl-2 were 1.66 ±0.02 and 0.71 0.05 (t =183.165,P =0.000),and the differences were statistically significant.③The semi-quantitative values of AKT of control group and experimental group two were 1.53 ± 0.01 and 0.72 ± 0.01 (t =135.281,P =0.000),and the semi-quantitative values of Bel-2 were 1.66 ± 0.02 and 0.63 ± 0.02 (t =128.814,P =0.000),and the differences were statistically significant.Conclusion PECAM-1 induced multidmg resistance of human nasopharyngeal squamous cell carcinoma CNE1 cells may be related to the activity of Bcl-2 through the signal pathway of PI3K/AKT.
