Background/Objective: Gall bladder carcinoma (GBC) is an aggressive malignancy with high mortality and aggressive course, with palliation as the only available option. The signs and symptoms of gall bladder arcinoma are not specific and often present late. Diagnosis is, therefore, often made at advanced stage with poorer outcomes. Identifying biomarkers and cancer specific cellular targets, that will pave the way for novel therapeutic approaches and early diagnosis for gall bladder carcinoma, is urgently needed. Proto-oncogenes (HER-2) and E-Cadherin are commonly deregulated in gallbladder cancer (GBC). This study evaluates the prognostic significance of HER-2 and E-Cadherin in GBC patients in Silchar Medical College.Our main objective was to evaluate frequency of HER-2/neu overexpression in GBC and to seek its correlation, if any with conventional clinicopathological parameters and survival.Methods: A total of 168 cases were received and evaluated for Gall Bladder cancer and control specimens were prospectively collected from 2018-2020. Immunohistochemical staining was done using monoclonal antibodies to semiquantitatively evaluate HER-2 and E-Cadherin protein expression. The criterion for HER-2 and E-Cadherin positivity was set at 10% and >5% tumor cells showing complete, membranous staining. Clinicopathological correlations were drawn with major clinical outcomes. Results: It was observed that out of 168 cases the male to female ratio is 1:5 with highest number of cases in the age group of 50-59 , i.e., 70 cases with 41.7%. The most common location in this study was fundus with 69% of cases (116 out 0f 168), most commonly presented as biliary colic with 56 number of cases. Grading was also done in 168 cases where most number of cases were moderately differentiated with 86 number of cases with a percentage of 51%. Expression of Her2Neu and E-Cadherin was evaluated where highest number of cases were seen with 1+ score  in the IHC expressions of both the markers with 81 and 61 number of cases respectively. Conclusion: The increasing global incidence, late presentation leading to poor prognosis and lack of effective therapy make the management of gall bladderv carcinoma really challenging. Our study shows the abnormal expression of HER-2 and E-Cadherin expression in gall bladder carcinoma patients in Southern Assam and suggests that  these two markers can be used for potential tool for early detection of gall bladder carcinoma and also can be used for targeted therapy in gall bladder carcinoma.

Background: C3 glomerulopathy is caused by dysregulation of the alternative complement pathway. Association with solid organ tumors is rare. However, there have been a few case reports of membranoproliferative glomerulonephritis secondary to gastrointestinal neoplasms. Case: A 38-year-old female presented with abdominal distension, loss of appetite, amenorrhea, and easy fatigability. She had been diagnosed 8 months back with C3 glomerulopathy and had received immunosuppression. On evaluation, she was incidentally detected to have Krukenberg tumor. The primary site of malignancy was gall bladder. Conclusion: Our case report highlights a possible association between C3 glomerulopathy and Krukenberg tumor secondary to gall bladder carcinoma and emphasizes the fact that even in cases of C3 glomerulopathy, occult malignancy should be considered as an underlying pathology.

Background: The present study highlights the occurrence of Incidental gallbladder carcinoma (IGBC) detected during histopathological examination in cholecystectomy specimens removed for cholelithiasis. Methods- This is a tertiary hospital based cross-sectional study of 500 cholecystectomy specimens removed during cholelithiasis. Relevant hospital records, histopathology slides and reports were reviewed, re-evaluated and studied. Results: 4(0.80%) cases of incidental gall bladder carcinoma (IGBC) were diagnosed from the histopathological evaluation (HPE) of 500 cholecystectomy specimens, constituting 0.80% of gall bladder specimens received during the study period. The age of the patients with IGBC ranged from 51-80 years. More females were affected than males with a M:F ratio of 1:3. Conclusion: Early detection of IGBC by histopathological examination would have a favourable impact on prognosis and management thereby increasing the survival outcome.

Background & objective: Ultrasonogram (USG) and computed tomography (CT) are often used in the evaluation of gall-bladder carcinoma. Thepresent study was conducted to determine the usefulness of USG and CT scan in diagnosing gallbladder carcinoma.Materials & Methods: This cross-sectional observational study was conducted at Department of Radiology and Imaging, BIRDEM in collaboration with the Departments of Hepato-biliary Surgery, and Histopathology of the same institute over a period of 3 years fromJuly 2004 to June 2006. A total of 42 patients (ranging from 40-80 years) were initially included on the basis of signs and symptoms of gallbladder carcinoma and underwent USG and CT scan for preoperative radiological diagnosis, its extension and operability. Following operation all the resected specimens were sent for histopathological evaluation. The diagnostic accuracies of USG and CT scan were then compared against histopathological diagnoses by using Kappa statistics.Result: In the present study, the mean age of the patients was 60 (range: 40-80) years with female preponderance. About 40% of the gall-bladder were contracted and reduced in size and 32.5% large and distended on USG examination, while 45% of the gall-bladder were contracted and reduced in size and 25% distended and large on CT examination. Approximately 40% had irregularly thickened wall and 21.2% diffusely thickened wall on USG and 30% of gallbladder wall were diffusely thickened and 45% irregularly thickened on CT scan. The present study showed hepatic parenchymal invasion to be 22.5% on USG and 42.5% on CT scan. The sensitivity and specificity of USG in diagnosing GB carcinoma were 93.9 and 71.4% respectively. Similarly, the sensitivity and specificity of CT scan in detecting GB carcinoma were 97.1 and 83.3% respectively. The test of agreement (Kappa test) revealed an almost 90% agreement between the two procedures meaning that the two diagnostic modalities are almost comparable in diagnosing gall bladder carcinoma (p<0.001).Conclusion: The study findings indicate that both USG and CT scan are ideal,non-invasive, safe imaging modalities for diagnosis of gallbladder carcinoma. CT scan has an additional advantage in defining the extension of the disease and involvement of surrounding structures including lymph nodes and hepatoduodenal ligament.Anwer Khan Modern Medical College Journal Vol. 8, No. 2: Jul 2017, P 105-111
