Abstract Background Due to rarity of duodenal GISTs, clinicians have few information about its clinical features, diagnosis, management and prognosis. Case report We report a case of promptly diagnosed duodenal GIST in a 61-year-old Egyptian man presented shocked with severe attack of hematemesis and melena. Upper gastroduodenal endoscopy was done and revealed a large ulcerating bleeding mass at first part of duodenum 4 hemo-clips were applied with good hemostasis. An exploratory laparotomy and distal gastrectomy, duodenectomy and gastrojejunostomy were performed. The morphology of the mass combined with immunohistochemistry was consistent with duodenal gastrointestinal stromal tumours (GISTs) of high risk type. The patient is on amatinib one tablet daily and he was well with no evidence of tumor recurrence. Conclusion despite being rare, emergency presentation with sudden severe, life-threatening hemorrhagic shock duodenal GISTs might be a cause of potentially lethal massive combined upper and lower gastrointestinal bleeding which is the key feature of this rare and challenging tumor.

Background: There is an ongoing need for targeted therapy and systemic treatment protocols for papillary thyroid carcinoma (PTC) patients. Yes activated protein-1 (YAP-1) has been found to control many targets of Hippo pathway. Annexin family is a huge family playing many roles in cellular processes. Annexin A10 (ANXA10) is a member of annexin family. Uncoordinated-5D (UNC5D), a recently discovered Unc5 family member which is found in normal tissues and downregulated in cancer cell lines and tissues. Aim of the study was to assess the expression of YAP-1, ANXA10, and UNC5D in PTC and in non-neoplastic tissues of thyroid gland using immunohistochemistry to evaluate their clinical significance and prognostic values in PTC patients.Method: In the present prospective study, we took samples from 60 patients with PTC and 30 samples from non-neoplastic thyroid tissues for YAP-1, ANXA10, and UNC5D immunohistochemistry. All the patients were followed up for assessment of the prognostic, clinical, and pathological of their expression.Results: Upregulation of YAP-1 and ANXA10 in addition to downregulation of UNC5D was found in PTC tissues more than non-neoplastic thyroid tissues. In PTC tissues, there were positive associations between high YAP-1 and ANXA10 expression, low UNC5D expression, tumor size (P = 0.022, 0.011, 0.014), presence of lymph node metastases (P = 0.005, < 0.001, 0.008), and inferior disease-free survival rate (P = 0.003, 0.01, 0.03).Conclusion: Upregulation of YAP-1 and ANXA10 expression and downregulation of UNC5D was associated with bad clincopathological criteria, disease progression, high incidence of disease recurrence, and poor survival.

Background: Aldehyde dehydrogenase 1 (ALDH1) is an enzyme accountable for the detoxification of aldehydes. Sex-determining region Y-box 9 (SOX-9) plays a role in many biological and pathological processes. In this study, we aimed to evaluate the prognostic significance of ALDH1 and SOX9 expression in early breast cancer. Method: The expression of ALDH1 and SOX-9 was evaluated through immunohistochemistry derived from 50 eligible patients with early breast cancer included in the current prospective cohort study. Results: Positive expression of ALDH1 and SOX-9 were detected in 29 (58%) and 34 (68%) patients, respectively. The positive expressions of both markers were statistically significant associated with increasing the stage, lymph nodes metastasis, high Ki67 labeling index, and molecular subtypes (P < 0.001), along with with the biological markers; estrogen receptors, progesterone receptors, and human epidermal growth factor receptor 2 over-expressions, and large tumor size (P = 0.039, P = 0.022, P = 0.024 and P = 0.003 for ALDH1 expression and P = 0.012, P = 0.007, P = 0.004 , and P = 0.002 for SOX-9 expression, respectively). There is a significant positive association between the expression of ALDH1 and SOX-9, r (correlation coefficient) = +0.806 (P < 0.001). Local recurrence was associated with the positive expression of ALDH1 only (P = 0.045) and the disease progression was statistically significant and associated with the positive expression of both ALDH1 and SOX-9 (P = 0.038, P = 0.023, respectively). There was significant association of positive expression of SOX-9 with reduced 3-y disease-free survival (P = 0.039). Conclusion: Positive expression of ALDH-1 and SOX9 were associated with aggressive histopathological features and poor outcome in early breast cancer and can be considered potential prognostic markers in this group of patients.

Ovarian cancer is the most lethal gynaecological neoplasm in females. In ovarian cancer, forkhead box A1 (FOXA1) aids transcription of YAP-associated protein mediated by the cyclic adenosine monophosphate response element-binding protein. As a result, cellular proliferation and migration increased. The roles of erythropoietin-producing human hepatocellular carcinoma cell (Eph) receptors and ephrin ligands in cell adhesion, migration, cell proliferation regulation in various cancers, and angiogenesis are well characterized. This study included formalin-fixed, paraffin-embedded tissue specimens from 41 patients with ovarian serous cystadenocarcinoma, including both low- and high-grade tumours. For each case, a paraffin block with tumour tissue was chosen for an immunohistochemical procedure using primary antibodies against EphA5 and FOXA1. By the end of 2017, patients finished their chemotherapy and were followed for the next 3 years. Positive FOXA1 and EphA5 results were presented in 68.3% and 39% of patients, respectively. A statistically significant correlation was detected between FOXA1 expression and each of CA-125 level, tumour stage, tumour grade, and the presence of lymph node metastasis. In our work, the overall survival was positively correlated with EphA5 expression and inversely correlated to FOXA1 immunoreactivity. The estimated disease-free survival (DFS) and EphA5 immunoreactivity had a significant positive association, whereas DFS and FOXA1 protein expression had a significant inverse link. FOXA1 and EphA5 expression play a role in ovarian cancer progression and prognosis prediction.

Background: Kinesin family member 23 (KIF23) has an important role in mitosis of cytoplasmic separation process. Casitas B-lineage lymphoma (c-Cbl) is a protein ligase E3 ubiquitin in tyrosine kinase pathways, involved in numerous cell types.The current study aimed to evaluate the tissue expression of KIF23 and c-Cbl in gastric cancer (GC) tissues and normal gastric mucosa using immunohistochemistry and to investigate the correlation among their expressions, clinicopathological parameters, and the prognosis of patients in order to detect their role in the progression of GC and patientsi prognosis.Method: We conducted this prospective study on 120 samples retrieved from 120 patients; 80 samples were taken from GC patients and 40 from normal gastric mucosa. We assed tissue protein expression of KIF23 and c-Cbl using immunohistochemistry. We evaluated the correlations between KIF23 and C-Cbl expression with clinicopathological and prognostic parameters of patients.Results: KIF23 expression level in GC tissues was positively correlated with high pTNM stage (P = 0.001), larger tumor size (P = 0.010), high tumor grade (P = 0.006), poor overall survival (P < 0.001), disease-free survival rates (P = 0.003), and tumor recurrence after therapy (P = 0.004). c-Cbl expression level in GC tissues was positively correlated with early pTNM stage (P = 0.003), lower tumor grade (P = 0.005), the absence of lymph node metastasis (P = 0.023), good response to therapy (P = 0.002), and the absence of tumor recurrence after the therapy (P = 0.004).Conclusion: The high KIF23 expression and low c-Cbl expression in GC tissues were attributed to progression and poor prognosis in gastric cancer patients.

Background: Gankyrin is an oncoprotein incriminated in cancer growth, invasion, and spread. Snail1 is associated with mesenchymal features acquisition that is related to invasion and metastasis of malignant cells. Isocitrate dehydrogenase 1(IDH1) has been found to be mutated in several cancers, which leads to altered cellular metabolism and tumorgenesis. The present study aimed to assess Gankyrin, Snail1, and IDH1 expression patterns and compare them to clinicopathological and prognostic parameters. Method: In our prospective cohort study, the samples taken from 60 renal cell carcinoma (RCC) patients were processed, diagnosed, graded, staged, and subjected to immunohistochemistry for Gankyrin, Snail1, and IDH1. The patients were chosen, treated, and followed up from January 2015 to December 2019. Overall survival (OS) and progression-free survival (PFS) were assessed. Results: High expression levels of Gankyrin were positively associated with high grade (P = 0.003), stage (P = 0.033), and size of the tumor (P = 0.049), in addition to lymph nodes metastasis (P = 0.01), distant metastases (P = 0.007), higher incidence of tumor progression, unfavorable 5-year PFS, and OS rates (P < 0.001). High expression levels of Snail1 were positively associated with high grade (P = 0.004) and stage (P = 0.023) of the tumors, on top of lymph nodes metastasis (P = 0.003), distant metastases (P = 0.002), higher incidence of tumor progression, poorer fiveyear PFS, and OS rates (P < 0.001). High expression levels of IDH1 were negatively associated with low grade (P = 0.002), stage, and size of the tumor and lymph nodes metastasis (P < 0.001), distant metastases (P = 0.041), lower incidence of tumor progression (P = 0.013), better five-year PFS, and OS rates (P < 0.041). Conclusion: We indicated the associations between poor RCC pathological parameters, unfavorable patients’ outcome, high Gankyrin, high Snail1, and reduced IDH1 expression.

Serous ovarian carcinoma (SOC) is an ovarian cancer with a high fatality rate. Therefore, a lot of researchers have tried to identify novel prognostic biomarkers which might improve the patient prognosis. The aims of the study were to detect the tissue protein expression of Beclin-1 in addition to HIF-1α in SOC patients, to evaluate the relationship between their expression, the clinicopathological parameters, patients’ prognosis, and the relation to chemotherapy resistance in SOC. We evaluated the expression of Beclin-1 in addition to HIF-1α in 60 patients with SOC using immunohistochemistry, followed all patients for about 36 months, analyzed associations between both markers' expression, clinicopathological data, and patients’ prognosis. Beclin-1 expression was related to low grade (p = 0.002), early SOC stage, absence of peritoneal spread (p = 0.006), and absence of lymph nodes, and distant metastases (p = 0.004 and

Background: Evaluation of cancer cervix prognosis is highly needed for novel targeted therapy and improved outcomes. Nucleolar and spindle associated protein 1 (NUSAP1) is a novel biomarker that has roles in spindle formation and mitotic progression. Maternal embryonic leucine zipper kinase (MELK) is involved in cell cycle control and carcinogenesis. The L1 cell adhesion molecule (L1-CAM) plays an essential role in cell migration. This study aimed to investigate NUSAP1, MELK, and L1CAM immunohistochemical expression in cancer cervix tissues and detect their prognostic roles. Method: In this prospective cohort study, we evaluated NUSAP1, MELK, and L1CAM expressions of sections from 62 cervical carcinoma cases using immunohistochemistry. Results: NUSAP1, MELK, and L1CAM expression correlated with tumor high grade, advanced FIGO stage, poor survival rates, and higher recurrence rate after successful therapy (p

Background and Objective: Diagnosis and discrimination of lung adenocarcinoma (LUAD) from lung squamous cell carcinoma (LUSC) is critical to select the appropriate treatment regimen as recently targeted therapies require accurate subtyping of NSCLCs. There are currently several biomarkers that could be used for differentiation between LUAD and LUSC, but they have less sensitivity, specificity, and clinical applicability. The aimof this study was to assess the diagnostic and prognostic values of CLCA2, SPATS2, ST6GALNAC1, and Adipophilin tissue expression in the tissues retrieved from LUAD and LUSC patients using immunohistochemistry. Methods:The current study was performed on the samples retrieved from sixty primary lung masses that were diagnosed as LUAD and LUSC. Immunohistochemistry was performed by using a panel of CLCA2, SPATS2, and ST6GALNAC1. We assessed the diagnostic roles of the studied markers in the discrimination between LUAD and LUSC and their prognostic values. Results: SPATS2 and CLCA2were expressed more in LUSC than LUAD. ST6GALNAC1 and Adipophilin were expressed more in LUAD than LUSC (p

Objective: Endocervical and endometrioid adenocarcinoma have marked overlapping features and the differentiation between them is important for their accurate management. Villin is an actin-binding protein which has an important role in the maintenance of microvilli in epithelial cells and epithelial cell-specific anti-apoptotic protein processes. Pro-Ex-C is a marker for higher-risk human papilloma virus (HPV) which targets the cell cycle proteins causing their overexpression. The aim of the study was to clarify the diagnostic and predictive role of villin, Pro-Ex-C, estrogen receptor (ER) and progesterone receptor (PR) expression in endocervical and endometrioid adenocarcinoma. Material and Method: We evaluated villin, Pro-Ex-C, ER and PR expressions in 15 cases of endocervical adenocarcinoma and 30 cases of endometrioid adenocarcinoma. We analyzed the diagnostic and predictive role of that panel in both carcinoma subtypes. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated. Results: Positive villin and Pro-Ex-C expressions were positively correlated with the presence and pattern of cervical stromal invasion (p
