Bladder cancer is the ninth most common type of cancer worldwide. We aimed to investigate the relationship between tumor grade, lamina propria invasion, muscularis propria invasion, and lymphovascular invasion and human epidermal growth factor receptor 2 (HER-2), cyclin D1, and alpha-methyl-CoA racemase (AMACR) expressions in bladder cancer.

The study included patients who underwent complete TURBT. In total, 72 cases of bladder cancer diagnosed by two pathologists were selected. AMACR, HER-2, cyclin D1 expressions were detected immunohistochemically.

The study population comprised 80% (57) males and 20% (15) females (mean age, 68 years). Further, 35 cases were noninvasive and 37 invasive urothelial carcinoma and 38 patients had low-grade tumor and 34 high-grade tumor. Intense immunostaining was observed with cyclin D1 for 75% tumors, AMACR for 39%, and HER-2 for 86%. High expressions of cyclin D1 and AMACR were observed in high-grade tumors (P < 0.05 and P < 0.005, respectively). High expression of HER-2 (2 and 3 positive) was found both at low- and high-grade tumors (84% and 88%, respectively).

Cyclin D1, AMACR expressions were found to be significant predictive factors of high-grade tumors. check details High Her-2 expression in patients with bladder carcinoma may indicate that they are potential targets for treatment. These markers may be important in determining prognosis of tumors and may be valuable for guiding treatment options.

Whole slide imaging (WSI) is an important component of digital pathology which includes digitization of glass slides and their storage as digital images. Implementation of WSI for primary surgical pathology diagnosis is evolving, following various studies which have evaluated the feasibility of WSI technology for primary diagnosis.

The present study was a single-center, observational study which included evaluation by three pathologists and aimed at assessing concordance on specialty-specific diagnosis and comparison of time taken for diagnosis on WSI and conventional light microscopy (CLM).

Seventy prostate core biopsy slides (reported between January 2016 and December 2016) were scanned using Pannoramic MIDI II scanner, 3DHISTECH, Budapest, Hungary, at 20× and 40×. Sixty slides were used for validation study following training with 10 slides.

Intraobserver concordance for diagnosis between the two platforms of evaluation was analyzed using Cohen's κ statistics and intraclass correlation coefficient (ICC); observation time for diagnosis was compared by Wilcoxon signed-rank test.

Interpretation on WSI using 20× and 40× was comparable with no major discordance. A high level of intraobserver agreement was observed between CLM and WSI for all three observers, both for primary diagnosis (κ = 0.9) and Grade group (κ = 0.7-0.8) in cases of prostatic adenocarcinoma. The major discordance rate between CLM and WSI was 3.3%-8.3%, which reflected the expertise of the observers. The time spent for diagnosis using WSI was variable for the three pathologists.

WSI is comparable to CLM and can be safely incorporated for primary histological diagnosis of prostate core biopsies.

The aim of this study was to evaluate the immunohistochemical expression of C4d in native renal biopsies of proliferative glomerular diseases, complement pathways in these diseases, and assess the relationship of C4d with histological and clinicopathological parameters, other complement proteins, and immunoglobulin markers.

This cross-sectional study was conducted during the year 2018-19 involving 107 native renal biopsies with histologically diagnosed cases of proliferative glomerular diseases. C4d immunohistochemical evaluation of renal tissue sections was performed using polyclonal antihuman C4d as the primary antibody. Patients were classified as positive and negative groups based on their glomerular C4d deposition.

The overall prevalence of C4d positivity was 80.4% in proliferative glomerular diseases ranging between 60.0% in C3 glomerulonephritis to 92.9% in membranoproliferative glomerulonephritis. Mixed capillary and mesangial deposition were noted in all cases of proliferative glomerulonephritis. Classical pathway was dominantly involved in all glomerular diseases except C3 glomerulonephritis and IgA nephropathy. Multivariate logistic regression analysis revealed that glomerular IgG staining (aOR 5.86, 95% CI 1.26-27.14) and IgM staining (aOR 3.90, 95%CI 1.07-14.18) were significantly associated with C4d positivity.

C4d staining along with immunoglobulin markers such as IgG and IgM and complement proteins can be useful in delineating different complement activation pathways in glomerular diseases and understanding the disease pathogenesis.

Gall bladder carcinoma is endemic in North India along the Ganges belt. Most of the cases usually present in late stage when prognosis is poor. That mandates a necessity for proper screening in these areas for gall bladder lesions. Tumor markers CA 19-9 and CA 125 have been studied in various GI cancers and may also help in the screening, diagnosis and evaluation of gall bladder carcinoma. Aims To assess serum CA19-9 and serum CA125 in patients with gall bladder lesions and find out a cut off value for diagnosis of carcinoma gallbladder.

Study included 118 cases, with female male ratio of 41.Out of it, 91 (77 %) cases were benign and 27 (23 %) were malignant. Patients' sera was collected and analyzed for CA19-9 and CA 125 by CMIA method.

The Mean (SD) value of CA19-9 for benign and malignant cases was found to be 12.86 (17.54) and 625.35(186.52) U/ml. For CA 125 it was found to be 17.98(13.69) and 239.63(73.72) U/ml respectively. The difference was statistically significant (P< 0.001). When Mean - 2SD value of malignant lesions were taken as cut off a value of CA 19-9 and CA 125 were found be 252.31 U/ml & 92.19U/ml respectively, found to be significant to suggest /diagnose a case of carcinoma gall bladder along with clinicoradiological findings. Taking these value as cut off Sensitivity & Specificity for CA 19-9 and CA 125 in detecting malignant cases were found to be 100% & 98.90% and 100% & 94.50% respectively.

It is concluded that both serum CA 19-9 and serum CA 125 may act as a good adjunct for diagnosis of cases of carcinoma gallbladder along with imaging studies. However, changes in CA19-9 are more significant than CA 125.

Gastric cancer is one of the most common cancers in the world and is responsible for over a million deaths. Gastric cancer broadly consists of two main histological types, diffuse and intestinal, and can be further classified as proximal (cardia) and distal (corpus and pylorus) cancers. The presence of Her2neu in certain cancers including gastric cancers has helped in throwing some light on the prediction of prognosis of the tumours. This study was carried out to assess and evaluate the role of Her2neu immunohistochemical expression in gastric cancers.

This study was carried out as a retrospective study on paraffin blocks of 70 gastrectomy specimens in the pathology department of our hospital. After the histological assessment and interpretation of data, appropriate blocks were chosen and sections of 3 micron thickness were cut and immunohistochemical staining of Her2neu was done and scoring was carried out.

We found that gastric cancer occurred predominantly in men as compared to women. Antrum was the most common site involved in gastric cancer (60%). In our study Grade 2 predominated (54%) than Grade 1 (4.2%) and Grade 3 (41%). According to the scoring system of Her2neu expression by immunohistochemistry in gastric cancer it was positive (3+) in 8 cases (11.4%), equivocal (2+) in 10 cases (14.3%) and negative (0+,1+) in 52 cases (74.3%). Her2neu was seen positive 13.7% of intestinal type tumours and in only 5.3% of diffuse type of tumours (P < 0.05).

Her2neu testing in gastric adenocarcinomas especially in histologically identified early gastric carcinoma is recommended.

Postoperative recurrence and metastasis of gastric cancer is still a difficult problem in medical field. About 60% of patients with advanced gastric cancer die from peritoneal metastasis, which has become one of the main causes of death of gastric cancer patients. To elucidate the molecular mechanism of peritoneal metastasis of gastric cancer can help us better early diagnosis and improve treatment measures.

This project intends to validate the above hypothesis from three different levels of tissue, cell, and animal models by means of fluorescence quantitative PCR, Western blot, double Luciferase Report Analysis and immunohistochemical detection, and to further explore the molecular mechanism of peritoneal metastasis of gastric cancer.

Our previous studies have shown that PARK7 promotes peritoneal metastasis of gastric cancer through PI3K/Akt signaling pathway, but its specific regulatory mechanism remains unclear.

Our preliminary study showed that the expression of microRNA-216b in gastric cancer tissues with peritoneal metastasis was significantly lower than that in patients without peritoneal metastasis, while the expression of PARK7 was the opposite.

Oesophageal cancer both squamous cell [SCC] and adenocarcinoma have poor outcomes with high morbidity and mortality. Our hospital-based registry for year 2017-2018 showed that oesophageal cancer constituted 22.7% of annual case load. The main objective of this study was to determine the presence of HER-2 receptors in patients with oesophageal carcinoma in our region.

From September 2018 to September 2019, data regarding expression of HER-2 receptors was analysed in 133 patients of oesophageal carcinoma. Data were statistically described as frequencies (number of cases) and percentages where appropriate. Chi-square and Fischer's exact test was used to find out the association between categorical variables. A P value less than 0.05 was considered as statistical significant at 95% confidence interval. The statistical analysis was performed using SSPS [statistical package for the social sciences] software version 17.0.

A total of 133 patients were taken into study. Majority of patients were males (96) with mean age of 52 years.
