RESUMEN
Objective To investigate the clinicopathological features of recurrent and de novo focal segmental glomerulosclerosis (FSGS) after kidney transplantation. Methods Thirty-four recipients pathologically diagnosed with FSGS by renal allograft biopsy were enrolled in this clinical trial. According to the detection of primary diseases of renal allografts and circulating permeability factors, 34 recipients were divided into the recurrent FSGS group (n=12) and de novo FSGS group (n=22). The differences of clinical indexes and the degree of pathological injury of renal allografts were compared between two groups. Results There was no significant difference in the mesangial hyperplasia score, glomerulosclerosis rate, renal tubular atrophy score, interstitial fibrosis score and podocyte proliferation rate between two groups (all P > 0.05). In the recurrent FSGS group, segmental glomerulosclerosis rate of the recipients was 0.10 (0.08, 0.27), lower than 0.19 (0.13, 0.33) in the de novo FSGS group (P < 0.05). No significant difference was found in the incidence of antibody-mediated rejection, drug-induced renal tubular injury and BK virus infection between two groups (all P > 0.05). The incidence of T cell-mediated rejection in the recurrent FSGS group was 17%, lower than 55% in the de novo FSGS group (P < 0.05). Immunohistochemical staining showed that the infiltrating inflammatory cells in the renal allografts were mainly T lymphocytes. The positive rates of C4d deposition in peripheral capillaries between the recurrent and de novo FSGS groups were 33% (4/12) and 32% (7/22), with no significant difference (P > 0.05). Immunofluorescence results revealed IgM deposition in the segmental glomerulosclerosis area of renal allografts in most cases. Electron microscopy showed extensive fusion or segmental distribution of podocytes in the glomerulus of renal allografts. Conclusions The degree of renal functional injury and the incidence of T cell-mediated rejection in the recurrent FSGS group are lower than those in the de novo FSGS group. Comprehensive analysis of preoperative and postoperative clinical manifestations, laboratory testing and pathological examination of kidney transplant recipients contribute to early diagnosis and treatment of recurrent and de novo FSGS.
RESUMEN
Objective To investigate the expression of centromere protein F(CENPF)in pancreatic ductal adenocarcinoma(PDAC)and its relationship with the clinicopathological features and prognosis of patients.Methods Based on Gene Expression Omnibus(GEO)from National Center for Biotechnology Information(NCBI),using GEO2R,Venn diagram,Cytoscape,MCODE and GEPIA software to screen out the suspected differential gene CENPF in PDAC;based on the Cancer Genome Atlas(TCGA)and the Genotype-Tissue Expression(GTEx),using NCBI,GEPIA,Ualcan,Oncomine,TIMER software and Kaplan-Meier on-line survival analysis tool to analyze its possible molecular mechanism from the level of messenger RNA(mRNA).In all,surgical specimens of 121 PDAC cases diagnosed at the pathology department of the First Affiliated Hospital of Fujian Medical Univer-sity were analyzed from the histoprotein level to analyze the relationship between CENPF and clinicopathological features and prognosis of PDAC.Results CENPF gene was abnormally expressed in various human cancers,and there was a difference in expression between pancreatic ductal adenocarcinoma and normal pancreatic tissue(P<0.05),and it was related to the grading(P<0.05)and prognosis(P=0.038)of pancreatic ductal adenocarcinoma.Immunohistochemistry showed that the expression of CENPF was correlated with nerve invasion(P=0.036),TNM stage(P=0.041),lymph node metastasis(P=0.023),degree of differentiation(P=0.020)and overall survival of pancreatic ductal adenocarcinoma(Log-rank=18.608,P=0.000016),and CENPF expression(HR=2.654,95%CI=1.373-5.131,P=0.004)was an independent risk factor for the prognosis of PDAC patients.CENPF combined with other key module genes in PDAC was mainly enriched in exosomes,extracellular mechanisms,and was related to serine endopeptidase activity and metalloendopeptidase activity.The action pathway of CENPF single gene in pancreatic ductal adenocarcinoma was mainly related to cell cycle,P53 pathway,ubiquitin-mediated proteolysis,and played a joint role with P53 and MDM2 in PDAC.Immune infiltration studies showed that CENPF expression was negatively correlated with CD4+T lymphocyte infiltration and positively correlated with dendritic cell infiltration(both P<0.05).Conclusion CEN-PF may be involved in the progression of PDAC,and high expression of CENPF indicates a poorer prognosis.Our research is expected to provide more scientific evidence for the prevention and treatment of PDAC.
RESUMEN
Objective To explore the predictive value of the enhanced CT imaging-based radiomics model and the clinical model for the serosal invasion in advanced gastric cancer.Methods The data were collected from 351 patients with advanced gastric cancer who underwent abdominal enhanced CT examination within 2 weeks before surgery,and the patients were randomly divided into a training group(n=247)and a validation group(n=104)in a ratio of 7:3.The 3190 radiomics features which were extracted from the arterial and venous phase CT images using A.K software were dimensionally reduced for constructing a radiomics model.The pathological features between serosal invasion positive and negative groups were compared,and the significant features were used to establish a clinical model.The model's performance was evaluated using receiver operating characteristic curve.Results In the training and validation groups,N staging and M staging were different in serosal invasion positive and negative groups(P<0.05).A total of 14 radiomic features were ultimately selected from the arterial and venous phase images.In the validation group,the diagnostic efficacy of the radiomic model for predicting serosal invasion in advanced gastric cancer was higher than that of the clinical model based on the combination of N staging and M staging(AUC:0.854 vs 0.793).Conclusion Both the radiomics model based on the enhanced CT imaging and the clinical model based on the combination of N staging and M staging can successfully predict serosal invasion in advanced gastric cancer,but the former performs better.
RESUMEN
Glomus tumor is a rare mesenchymal neoplasm arising from the modified smooth muscle cells of the glomus body. Primary crissum glomus tumor is extremely rare without any published in the literature. In this article, we report the first case of primary crissum glomus tumor in an 80-year-old man with recurrent anal pain for 8 years, increased pain for 1 year. Rectal MRI for inflammatory lesions (sinus tract). Microscopic examination showed the tumor cells were arranged in sheets and nests, surrounding blood vessels and nerve bundles. At high magnification, the neoplastic cells show regular round shape with light eosinophilic and translucent cytoplasm. The cell boundary is clear, the nucleus is round and located in the center. The stroma of the tumor shows hyaline degeneration. Immunohistochemically, the tumor cells were positive for smooth muscle actin, h-caldesmon, Calponin, synaptophysin, Collagen IV and CD34, but completely negative for HMB45, S100, EMA, desmin, CgA and CD56. The histologic features and immunohistochemical profile supported a diagnosis of primary crissum glomus tumor. The patient was asymptomatic and disease free after the procedure.
RESUMEN
The relationship between the long noncoding RNA (lncRNA) expression and oesophageal cancer prognosis has been widely studied, but less consensus has been reached. We conducted this study to evaluate the relationship between the expression of lncRNAs and the prognosis and clinical pathology of oesophageal cancer. We conducted a systematic search of PubMed, EMBASE and Cochrane Library until 25 January 2019. Studies that evaluated the associations of a specific lncRNA with survival and/or clinicopathology of oesophageal cancer were included. Pooled hazard ratios (HRs), odds ratios (ORs), and corresponding 95% confidence intervals (CIs) were calculated using fixed or random-effect models. Sensitivity analysis was used to verify the stability of results. Publication bias was detected using Begg tests and adjusted utilizing the trim-and-fill method if a bias existed. A total of 51 studies comprising 6510 patients and regarding 41 lncRNAs were included in the present systematic review and meta-analysis. The results showed that dysregulation of lncRNAs was associated with overall survival, disease-free survival, and progression-free survival. The expression of lncRNAs was related to some certain clinicopathological parameters of oesophageal cancer, including tumour size, T classification, lymph node metastasis, tumour node metastasis (TNM) stage and differentiation. Among these findings, lncRNA AK001796, CASC9, HOTAIR, MALAT1 and UCA1 were identified and were expected to be ideal biomarkers for the prognosis and clinicopathology of oesophageal cancer. Although significant publication bias was observed in some studies, the results were not changed after adjustment using the trim-and-fill method. Abnormal lncRNA-expression profiles could serve as a promising indicator for prognostic evaluation of patients with oesophageal cancer. The combination of these lncRNAs will contribute to clinical decision-making in the future.
RESUMEN
Objective: To explore and analyze the differences of clinicopathological features and prognosis and influencing factors in young breast cancer patients in different age groups. Methods: A total of 277 female breast cancer patients with invasive ductal carcinoma under 40 years old who were diagnosed and treated by operation at the International Peace Maternity & Child Health Hospital, Shanghai Jiao Tong University School of Medicine from Jan. 2010 to Dec. 2018 were retrospectively analyzed. The patients were divided into two groups by the age of 35 years old, i.e. aged ≤ 35 group and aged >35 and ≤ 40 group. The differences of clinicopathological features were compared between the two groups, including histological classification of cells, tumor size, lymph node metastasis, estrogen receptor (ER) expression, progesterone receptor (PR) expression, human epidermal growth factor receptor-2 (HER2) expression, the expression of Ki-67, the degree of intravascular invasion, pathological stage and molecular subtype. The prognostic differences and influencing factors of the two groups were analyzed. Results: There were no significant differences in histological classification of cells, tumor size, lymph node metastasis, ER expression, PR expression, HER2 expression, the expression of Ki-67, the degree of intravascular invasion, pathological stage and molecular subtype between the two groups. The 3-year disease-free survival (DFS) of the patients in the aged ≤ 35 and >35 and ≤ 40 group were 89.66% and 95.03%, respectively, and there was no significant difference. There was no statistically significant difference in the 3-year DFS among the four molecular subtypes between the two groups. Cox proportional hazards model showed that intravascular invasion and lymph node metastasis were the independent risk factors of DFS. Conclusion: >35 and ≤ 40 year-old breast cancer patients and ≤ 35 year-old breast cancer patients have similar clinicopathological features and prognosis, so the same treatment strategy should be given.
RESUMEN
@#[Abstract] Objective: To compare the differences in clinical and pathological features and survival time between patients with left -sided colon cancer and rectal cancer. Methods:Atotal of 323 patients with colorectal cancer (CRC) underwent surgical resection at Changhai Hospital of the Second Military Medical University between January 2011 and January 2012 were enrolled in this study. The clinical data of patients were collected and the follow-up was started from the day of surgery or pathological confirmation with the death of patients as endpoints. The follow-up lasted untilAugust 1,2017. Results: There were significant differences in initial symptoms, pathologic type, tumor stage, anemia before surgery, p53 positive rate, and BRAF mutation (χ2=59.088, 4.188, 24.305, 11.956, 4.221, 4.001, all P<0.05) between patients with left-sided colon cancer and rectal cancer. For all the patients, the median survival time was not observed. The five-year survival rates of patients with left-sided colon cancer and rectal cancer were 79.2% and 74.3%, respectively. The Kaplan-Meier survival curves of patients at StageⅠ-Ⅱshowed that there was no statistical difference between patients with left-sided colon cancer and rectal cancer(P=0.840) and the survival of Stage Ⅲ patients between the two groups also showed no statistical difference (P=0.106). Cox regression analysis showed that both the pathologic types [HR=1.759, P=0.047] and tumor stage [HR=2.104, P<0.001] were independent predictive factors for OS of CRC patients. Conclusion: There were no differences in survival time between patients with left-sided colon cancer and rectal cancer. The pathologic types and tumor stage were factors influencing the OS of CRC patients.
RESUMEN
Objective: To study the correlation between KRAS, NRAS and BRAF mutations and the clinicopathological features in patients with colorectal cancer (CRC). Methods: The 461 paraffin-embedded CRC tissues were collected. The mutations in hotspot region of KRAS, NRAS and BRAF genes were investigated using amplification refractory mutation system. The relationship between the mutation rates of each gene and the clinicopathological characteristics in CRC patients were analyzed. The KRAS and BRAF mutation profile and the impact on promoter methylation of the downstream genes were further investigated in both CRC tissues and cell lines through literatures and the American Type Culture Collection. Results: KRAS, NRAS and BRAF mutation rates in CRC tissues were 44.0%, 6.1% and 5.2%, respectively. KRAS mutations in the right colon were remarkably higher than the left colon (P=0.000). NRAS mutations were more likely to occur in male patients than female patients (P=0.002). BRAF mutation was closely correlated with age, tumor differentiation, tumor location and nerve invasion, but was exclusive of 203 KRAS mutated samples. Conclusion: KRAS, NRAS and BRAF mutations were significantly correlated with the clinicopathological features of CRC, and the mutation incompatibility was observed between KRAS and BRAF genes.
RESUMEN
OBJECTIVE@#In this study, we aimed to expand current knowledge of head and neck squamous cell carcinoma (HNSCC)-associated long noncoding RNAs (lncRNAs), and to discover potential lncRNA prognostic biomarkers for HNSCC based on next-generation RNA-seq.@*METHODS@#RNA-seq data of 546 samples from patients with HNSCC were downloaded from The Cancer Genome Atlas (TCGA), including 43 paired samples of tumor tissue and adjacent normal tissue. An integrated analysis incorporating differential expression, weighted gene co-expression networks, functional enrichment, clinical parameters, and survival analysis was conducted to discover HNSCC-associated lncRNAs. The function of CYTOR was verified by cell-based experiments. To further identify lncRNAs with prognostic significance, a multivariate Cox proportional hazard regression analysis was performed. The identified lncRNAs were validated with an independent cohort using clinical feature relevance analysis and multivariate Cox regression analysis.@*RESULTS@#We identified nine HNSCC-relevant lncRNAs likely to play pivotal roles in HNSCC onset and development. By functional enrichment analysis, we revealed that CYTOR might participate in the multistep pathological processes of cancer, such as ribosome biogenesis and maintenance of genomic stability. CYTOR was identified to be positively correlated with lymph node metastasis, and significantly negatively correlated with overall survival (OS) and disease free survival (DFS) of HNSCC patients. Moreover, CYTOR inhibited cell apoptosis following treatment with the chemotherapeutic drug diamminedichloroplatinum (DDP). HCG22, the most dramatically down-regulated lncRNA in tumor tissue, may function in epidermis differentiation. It was also significantly associated with several clinical features of patients with HNSCC, and positively correlated with patient survival. CYTOR and HCG22 maintained their prognostic values independent of several clinical features in multivariate Cox hazards analysis. Notably, validation either based on an independent HNSCC cohort or by laboratory experiments confirmed these findings.@*CONCLUSIONS@#Our transcriptomic analysis suggested that dysregulation of these HNSCC-associated lncRNAs might be involved in HNSCC oncogenesis and progression. Moreover, CYTOR and HCG22 were confirmed as two independent prognostic factors for HNSCC patient survival, providing new insights into the roles of these lncRNAs in HNSCC as well as clinical applications.

RESUMEN
In patients with colorectal cancer (CRC), the BRAF V600E mutation has been reported to be associated with several clinicopathological features and poor survival. However, the prognostic implications of BRAF V600E mutation and the associated clinicopathological characteristics in CRCs remain controversial. Therefore, we reviewed various clinicopathological features, including BRAF status, in 349 primary CRCs and analyzed the relationship between BRAF status and various clinicopathological factors, including overall survival. Similar to previous studies conducted in Eastern countries, the incidence of the BRAF V600E mutation in the current study was relatively low (5.7%). BRAF-mutated CRC exhibits distinct clinicopathological features from wild-type BRAF-expressing cancer independent of the microsatellite instability (MSI) status. This mutation was significantly associated with a proximal tumor location (P = 0.002); mucinous, signet ring cell, and serrated tumor components (P < 0.001, P = 0.003, and P = 0.008, respectively); lymphovascular invasion (P = 0.004); a peritumoral lymphoid reaction (P = 0.009); tumor budding (P = 0.046); and peritoneal seeding (P = 0.012). In conclusion, the incidence of the BRAF V600E mutation was relatively low in this study. BRAF-mutated CRCs exhibited some clinicopathological features which were also frequently observed in MSI-H CRCs, such as a proximal location; mucinous, signet ring cell, and serrated components; and marked peritumoral lymphoid reactions.

Objective:This work aims to detect the levels of miR-200c/141 methylation and miR-200c/141 in gastric cancer tissue and investigate the relationship between miR-200c/141 expression and clinical parameters. Methods:The methylation status of miR-200c/141 CpG island and miR-200c/141 in gastric cancer tissue specimens was evaluated by qRT-PCR or BS-MSP method. We analyzed the relationship among the methylation status of miR-200c/141 CpG island, expression level of miR-200c or miR-141, and clinical parame-ters. Results:The status of miR-200c/141 CpG island methylation in gastric cancer tissue was significantly higher compared with that in paracarcinoma tissue. MiR-200c and miR-141 were markedly decreased in gastric cancer tissue compared with those in adjacent tis-sue. MiR-200c/141 CpG island methylation was negatively related with the expression of miR-200c and miR-141 in gastric cancer speci-mens. Conclusion:The upregulation of miR-200c/141 CpG methylation inhibits miR-200c/141 expression in gastric cancer tissue.
RESUMEN
Purpose To discuss the clinical,histopathological characteristics,diagnosis,differential diagnosis and prognosis of malignant intraductal papillary lesions of the breast.Methods 28 cases of malignant intraductal papillary lesions of the breast were analyzed by histology and immunobistochemistry.Clinical and follow-up information was obtained.The published relevant literatures were reviewed.Results All the patients were females with a mean age of 55.7 years.The clinical features were a palpable mass or nipple discharge.28 cases were diagnosed including 22 cases of intraductal papaillary carcinoma,2 cases of encapsulated papillary carcinoma and 4 cases of solid papillary carcinoma.Microscopically,the tumor showed solid and papillary area inside the capsule wall with fine delicate fibrovascular septa.The tumor cells usually displayed low-grade nuclear features.Immunohistochemistry,the tumor cells revealed diffusely strong positive ER and PR in almost all cases and HER-2,CK5/6 were negative positive.All cases were negatiive for CK5/6,p63 and SMA in the celluar nodules.CD56,Syn and CgA were found positively in some solid papillary carcinoma cases.The average positive rate of Ki-67 in tumor cells was 5.3 %.27 patients were available for follow-up examination from 10 to 79 months and all the patients were alive.Conclusion Malignant intraductal papillary lesions of the breast most occurs in postmenopausal women.The diagnosis should be based on the clinical information,histopathological features and immunohistoehemistry stain due to its diverse histology.The main differential diagnosis is intraductal papilloma.This kind of lesion is a low grade malignant tumor with favorable prognosis.
RESUMEN
Objective:Influence of clinicopathological characteristics and different therapy patterns on the overall survival of patients with gastric cancer with bone metastasis was investigated. Methods:A total of 146 gastric cancer patients with bone metastasis were enrolled from December 1996 to December 2014. Data of clinicopathological characteristics, treatment methods, and overall survival were collected. Univariate and multivariate analyses were performed using log-rank tests and Cox's proportional hazard model, respec-tively. Results:A total of 51 (34.9%) patients had synchronous metastasis, while 95 (65.1%) had metachronous metastasis. Moreover, 35 (24.0%) patients only had bone metastasis, while 111 (76.0%) patients were complicated with other organ metastases, such as liver (30.0%), peritoneal (24.0%), lung (15.1%), and bone marrow (7.5%). After diagnosis of bone metastasis, bisphosphonates, bone radio-therapy and bone surgery were applied in 99 (67.8%), 34 (23.3%), and 5 (3.4%) patients, respectively. Additionally, 96 (65.6%) patients received palliative chemotherapy. The median overall survival was 5.8 months (95%CI:4.284-7.316). Multivariate analysis revealed that KPS<80 (P=0.030), bone marrow metastasis (P<0.001), elevated serum CA199 (P<0.001), and without palliative chemotherapy (P<0.001) were independent poor prognostic factors. Conclusion:The outcome of gastric cancer with bone metastasis is very poor, espe-cially in patients with bone marrow metastasis, worse KPS, and elevated CA199. Palliative chemotherapy may be beneficial for the sur-vival of these patients.

RESUMEN
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.

Purpose To discuss the clinical,histopathological characteristics,diagnosis,differential diagnosis and prognosis of hydroa vacciniforme-like lymphoproliferative disorder in children.Methods 6 cases of hydroa vacciniforme-like lymphoproliferative disorder were analyzed by molecular,histopathological and immunohistochemical testing.Clinical and follow-up information was obtained.The published relevant literatures were reviewed.Results 4 cases were boys,2 case were girls.All the patients presented with erythema and blisters with fever for 1 month to 4 years.Histopathologic examination showed an mild or moderate atypical lymphocytic infiltrate with angiotropism and angiocentricity,and scattered or dense lymphoid infiltration throughout the dermis and subcutaneous tissue.Blisters or necrosis could be seen in the epidermis.The atypical lymphocytes were positive for CD2,CD3,CDS,CD7,CD43,TIA-1,CD4 or CD8,and negative for CD20,Pax-5.Only one case showed positive stain for CD56.The average positive rate of Ki67 in tumor cells was 42.3%.Tumor cells positive for EBV encoded RNA (EBER) were detected in cutaneous infiltrates in 5 cases.Gene rearrangement of TCR was detected in 2 cases.5 patients were available for follow-up examination and 1 patient was dead.Conclusion Hydroa vacciniforme-like lymphoproliferative disorder is a rare disease mainly occuring in children.Chronic active EBV infection has been associated with this disease.It may be a spectrum in terms of its clinical course,and may be benign,borderline and malignant.Pathological diagnosis should be closely combined with clinical data.
RESUMEN
BACKGROUND: Rosacea is characterized by erythema of the central face that persists for several months or longer. Reports of the histological changes in rosacea are scarce, and few attempts have been made to correlate such changes with clinical findings and pathophysiology. OBJECTIVE: This study aimed to elucidate the clinical manifestations of rosacea and investigate its histological features. METHODS: We performed a retrospective analysis of 278 patients with histologically confirmed rosacea who visited the Department of Dermatology at the Catholic Medical Center between January 2008 and May 2013. Clinical subtypes, disease severity, and precipitating factors were evaluated. In 115 randomly selected patients, histopathological features were evaluated as well. RESULTS: The ratio of males to females was 1:1.8. The age distribution showed a peak incidence in the fifth decade. The most common subtype was papulopustular rosacea (52.9%) followed by erythematotelangiectatic rosacea (34.9%), ocular rosacea (4.0%), and phymatous rosacea (2.9%). Granulomatous rosacea accounted for 5.4% of rosacea cases. Precipitating factors included hot weather (54.7%), stress (51.8%), sun exposure (37.4%), alcohol (37.4%), and hot baths (33.1%). Histological analysis of skin biopsies from 115 patients revealed solar elastosis in 62 patients (53.9%) and telangiectasia in 85 patients (73.9%). CONCLUSION: In this study, Korean rosacea patients were predominantly female with a peak age in the fifth decade and the majority suffered from the papulopustular and erythematotelangiectatic types of rosacea. Histological observations pertaining to each rosacea type were also discussed.
