Incidental Gall Bladder Adenocarcinoma in Cholecystectomy Specimens; A Single Center Experience and Review of the Literature

BACKGROUND Gallbladder adenocarcinoma is the most common malignant tumor of the biliary tract. Most of gall bladder cancers are detected incidentally only after pathological examination of the surgical specimens. In this study we investigated the characteristics of incidental gallbladder cancers in our center and also reviewed the current literature regarding the diagnosis and treatment of such incidentally detected tumors in the gall bladder. METHODS We retrospectively reviewed all of the cholecystectomy specimens in the archives of Pathology Department in the hospitals affiliated to Shiraz University of Medical Sciences in the study period (2010-2016). Clinicopathological characteristics were extracted from the patients’ clinical charts, which included symptoms, radiological findings, laboratory data, and surgical procedures as well as outcome. RESULTS During these 7 years we identified 18 cases of incidental gall bladder cancer, consisted of 13 women and 5 men with the age range of 32 to 85 (62.5 ± 14.2) years detected after pathological study of the resected gall bladders among more than 4800 resected gall bladders. During the period, only two patients were operated on with the impression of gall bladder adenocarcinoma, which was not included in the study. Ten cases were T1 and eight were T2 at the time of surgery. They have been followed up for 1-7 years, during which, six cases of T2 died. All of the T1 cases are alive and symptom free. CONCLUSION By increasing laparoscopic cholecystectomies in our center we observed 0.37% incidental cases of gall bladder adenocarcinoma. Preoperative diagnosis of this cancer in early stages is very difficult and needs high degree of suspicion. The most important predictor of prognosis is the stage of the cancer at the time of surgery. To the best of our knowledge, this is the first report of incidental gall bladder cancer from Iran.

Introduction: Gall bladder cancer is the most common cancer of the biliary tree and one of the highly malignant tumors with poor prognosis. Although its incidence is low in west, it is common in our part of the world. There are very few studies regarding gall bladder cancer in Nepal. The incidence of gallstones in patients with gall bladder cancer is high. The aim of the study was to evaluate the clinicopathological aspect of the disease in patients with gallbladder cancer and to Asses the incidence of gallstones in patients with gall bladder cancer.Material and Methods: This was a retrospective study carried out in GI Surgery unit of National Academy of Medical Science, Bir Hospital, Kathmandu, Nepal. All patients diagnosed as gallbladder carcinomas during 12 years period from 2002 to 2014 were included in this study. Their clinical characteristics, laboratory data, tumor histopathology reports were obtained and analyzed using SPSS17.Results: Total of 47 patients who met inclusion criteria were included in the study. Male to Female ratio was 1:1.8. Age ranged from 32 to 72 years with mean age of 54. Most common presenting symptom was Pain abdomen (93.6%) followed by weight loss (51.1%) and Jaundice (46.8%). Most common finding on examination was Icterus (42.6%) followed by palpable gall bladder (34%) and Hepatomegaly (29.8%). Gall Stones were seen in 37 (72.3%) patients. Most common histopathology was Adenocarcinoma (93.6%).Conclusion: Most of the patient with gall bladder cancer remained asymptomatic until late. Pain abdomen was most common presenting symptom and icterus was most common findings. There was strong association between gall bladder cancer and gallstones. There should be high index of suspicion if patient with gallstones has constant pain in right hypochondrium and has jaundice.

Background: The aberrant alteration in Jab1 signalosome (COP9 Signalosome Complex Subunit 5) has been proven to be associated with the progression of several carcinomas. However the specific role and mechanism of action of Jab1 signalosome in carcinogenesis of gall bladder cancer (GBC) are poorly understood. Objective: The main objective of our study was to elucidate the role and mechanism of Jab1 signalosome in gall bladder cancer by employing siRNA. Methods: Jab1 overexpression was identified in gall bladder cancer tissue sample. The role of Jab1-siRNA approach in cell growth inhibition and apoptotic induction was then examined by RT-PCR, Western Blotting, MTT, ROS, Hoechst and FITC/Annexin-V staining. Results: In the current study, we have shown that overexpression of Jab1 stimulated the proliferation of GBC cells; whereas downregulation of Jab1 by using Jab1-siRNA approach resulted incell growth inhibition and apoptotic induction. Furthermore, we found that downregulation of Jab1 induces cell cycle arrest at G1 phase and upregulated the expression of p27, p53 and Bax gene. Moreover, Jab1-siRNA induces apoptosis by enhancing ROS generation and caspase-3 activation. In addition, combined treatment with Jab1-siRNA and gemicitabine demonstrated an enhanced decline in cell proliferation which further suggested increased efficacy of gemcitabine at a very lower dose (5μM) in combination with Jab1-siRNA. Conclusion: In conclusion, our study strongly suggests that targeting Jab1 signalosome could be a promising therapeutic target for the treatment of gall bladder cancer.

Hoechst Staining

Background:Plant sterols have proven a potent anti-proliferative and apoptosis inducing agent against several carcinomas including breast and prostate cancers. Jab1 has been reported to be involved in the progression of numerous carcinomas. However, antiproliferative effects of sterols against Jab1 in gall bladder cancer have not been explored yet.Objective:In the current study, we elucidated the mechanism of action of stigmasterol regarding apoptosis induction mediated via downregulation of Jab1 protein in human gall bladder cancer cells.Methods:In our study, we performed MTT and Trypan blue assay to assess the effect of stigmasterol on cell proliferation. In addition, RT-PCR and western blotting were performed to identify the effect of stigmasterol on Jab1 and p27 expression in human gall bladder cancer cells. We further performed cell cycle, Caspase-3, Hoechst and FITC-Annexin V analysis, to confirm the apoptosis induction in stigmasterol treated human gall bladder cancer cells.Results:Our results clearly indicated that stigmasterol has up-regulated the p27 expression and down-regulated Jab1 gene. These modulations of genes might occur via mitochondrial apoptosis signaling pathway. Caspase-3 gets activated with the apoptotic induction. Increase in apoptotic cells and DNA were confirmed through annexin V staining, Hoechst staining, and cell cycle analysis.Conclusion:Thus, these results strongly suggest that stigmasterol has the potential to be considered as an anticancerous therapeutic agent against Jab1 in gall bladder cancer.
