INDIAN J PATHOL MICR 2024; 67:367-373. [PMID: 38391184 DOI: 10.4103/ijpm.ijpm_463_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 12/28/2022] [Indexed: 02/24/2024] Open
Abstract
OBJECTIVE To study the spectrum and distribution of histopathological changes and evaluate immunohistochemistry markers p53 protein and Ki67 antigen in various lesions of gall bladder. MATERIALS AND METHODS A total of 804 consecutive gall bladder specimens were evaluated. Forty cases were selected for immunohistochemical analysis to evaluate expression of p53 and ki67 proliferation index, including 20 carcinoma gall bladder cases and 20 cases of inflammatory pathology associated with metaplasia, atypia, hyperplasia, dysplasia, and adenoma. p53 immunostaining was categorized as wild type and mutant type. ki67 of >20% was considered high expression. RESULTS The majority of the gall bladder lesions were inflammatory in origin, most common being chronic cholecystitis. In the group of 20 gall bladder carcinoma cases, 65% were p53 mutant and the remaining 35% cases had a p53 wild-type immunophenotype. 55% cases showed high expression for ki67 labeling. However, significant correlation ( P < 0.05) was seen with lympho-vascular invasion. Among non-malignant lesions, normal/wild-type p53 expression was seen with increasing intensity and positivity in lesions with atypia and intra-epithelial neoplasms. Ki67 index also showed the same trend in all cases. CONCLUSIONS p53 and ki-67 expression increases in inflammation, and further increment occurs in premalignant and malignant lesions of the gall bladder epithelium and can be used as a marker of aggression of histopathological lesions. The results emphasize the potential of Ki-67 and p53 as biomarkers of carcinogenesis in gall bladder carcinoma.

J Carcinog 2021; 20:11. [PMID: 34729043 PMCID: PMC8511828 DOI: 10.4103/jcar.jcar_9_21] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Revised: 05/01/2021] [Accepted: 05/12/2021] [Indexed: 11/23/2022] Open
Abstract
INTRODUCTION: Gallbladder cancer is an aggressive cancer with short median survival from the time of diagnosis. Improved understanding of the pathological molecular mechanisms of gallbladder carcinogenesis is important to refine the diagnosis, prognosis, and also to develop novel targeted therapies for patients with advanced Gallbladder cancer (GBC) malignancy. Ki-67 is a marker of cell proliferation and its detection by immunohistochemistry is considered to be an effective method for the detection of prognosis in several tumors. In the present study, we have analyzed expression of immunohistochemical marker Ki-67 in gallbladder carcinoma and its correlation with clinicopathological and radiological parameters. MATERIALS AND METHODS: This prospective observational study was conducted from December 2017 to July 2020. The patients of newly diagnosed gallbladder cancer were enrolled as per the inclusion and exclusion criteria defined in the study protocol. Contrast-enhanced computer tomography of the chest and abdomen and serum tumor markers such as carbohydrate antigen (CA)-19.9, carcinoembryonic antigen, and CA 125 were done. Immunohistochemical expression of Ki-67 was evaluated on biopsy tissue from the gallbladder mass. RESULTS: Fifty newly diagnosed patients of carcinoma gallbladder were included in the present study. The correlation was studied between clinicodemographic parameters and Ki-67, but no association was found with age, gender, and symptoms. There was a weak positive correlation between Ki-67 and direct bilirubin, serum glutamic pyruvic transaminase, serum glutamic oxaloacetic transaminase, and alkaline phosphatase (P = 0.094; 0.126; 0.542; and 0.328, respectively). There was a weak positive correlation between body mass index (Kg/m2) and Ki-67, but this correlation was not statistically significant (P = 0.304). CONCLUSIONS: Ki-67 is a marker of proliferation and it correlated with histological differentiation, jaundice and liver function tests, presence of stones, and location of metastases but did not correlate with stage and extent of disease.

Expression of Human epidermal growth factor receptor 2, Survivin, Enhancer of zeste homolog -2, Cyclooxygenase-2, p53 and p16 molecular markers in Gall bladder carcinoma. J Carcinog 2021; 20:7. [PMID: 34321957 PMCID: PMC8312376 DOI: 10.4103/jcar.jcar_4_21] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2021] [Revised: 02/26/2021] [Accepted: 03/05/2021] [Indexed: 12/28/2022] Open
Abstract
INTRODUCTION: Gallbladder cancer exhibits striking variability in the global rates, reaching epidemic levels for some regions and ethnicities. The basis of its variability resides in differences in environmental exposure and intrinsic genetic predisposition to carcinogenesis. There is little information present regarding genetic and molecular alterations in gall bladder cancer (GBC). We, therefore, have evaluated the molecular marker expression in GBC and studied their correlation with clinicopathological staging. MATERIALS AND METHODS: This prospective observational study was conducted on newly diagnosed GBC patients from July 2017 to July 2020. After complete staging workup, the GBC biopsy samples paraffin block was tested for molecular markers estrogen receptor (ER), progesterone receptor (PR), p53, p16, Human epidermal growth factor receptor 2 (HER 2-neu), Survivin, Enhancer of zeste homolog-2 (EZH2), and Cyclooxygenase-2 (COX-2) expression by immunohistochemistry. RESULTS: Fifty newly diagnosed patients of carcinoma gall bladder were included in the present study. Age was ranged from 29 – 69 years (mean 53.42). p53 was the most common positive marker in 74% of patients, survivin in 58%, COX-2 in 44%, and p16 in 42% whereas Her 2 neu and EZH-2 were positive in 16% of patients each. None of the patients of GBC were ER or PR positive. There was a significant difference between the various groups in terms of the distribution of histological grade and Her 2 neu (χ2 = 9.886, P = 0.014) but not with other markers. Furthermore, there was a significant difference in terms of distribution of p16 and p53 with stage (χ2 = 7.017, P = 0.037 and χ2 = 5.861, P = 0.033) respectively. CONCLUSIONS: The present study shows the expression of molecular markers Her2 neu, p53, p16, survivin, COX-2, and EZH-2 in GBC. Now the time has come, and it is also the need of the day to establish early biomarkers of this highly lethal malignancy. It can be used in future for the detection of disease in the early phase and targeted therapy.

Hum Pathol 2021; 114:44-53. [PMID: 33989638 DOI: 10.1016/j.humpath.2021.05.001] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 04/29/2021] [Accepted: 05/04/2021] [Indexed: 02/07/2023]
Abstract
Invasive gallbladder carcinoma (GBC) is preceded by two main types of precursor lesions: intracholecystic papillary-tubular neoplasms (ICPNs) and biliary intraepithelial neoplasias (BilINs). Invasive GBCs with an ICPN component have more favorable prognoses than those without an ICPN component. Some BilINs show a relatively exophytic papillary pattern but do not meet the ICPN criteria; at our institution, we call these papillary neoplasias. To clarify the clinical significance of papillary neoplasia, we herein examined 80 invasive GBCs and classified them into three groups based on the type of preinvasive lesions: those with ICPN (ICPN group, n = 35), those with papillary neoplasia (pap-neoplasia group, n = 13), and those without ICPN/papillary neoplasia (group without ICPN/pap-neoplasia, n = 32). We then compared the prognostic differences and characterized the tumors of each group by determining the immunohistochemical expressions of various biomarkers. The overall survival periods of the ICPN and pap-neoplasia groups were significantly longer than that of the group without ICPN/pap-neoplasia (P < 0.0001, P = 0.0036, respectively). Multivariate analysis revealed that lacking ICPN/papillary neoplasia was independently associated with poor prognosis (P = 0.0007), as were poor differentiation (P = 0.0395), presence of preoperative symptoms (P = 0.0488), and advanced stage (P = 0.0234). Invasive components of the ICPN and pap-neoplasia groups were characterized by higher expressions of p16 and p53 compared with those of the group without ICPN/pap-neoplasia. The prognoses of the invasive GBCs with either papillary neoplasia or ICPN were thus more favorable than those of the invasive GBCs without ICPN/pap-neoplasia. Invasive GBCs with exophytic papillary preinvasive lesions (ICPN and papillary neoplasia) may be biologically different from those without such lesions.

Abstract
AIMS Gallbladder carcinomas usually present in advanced stages and has a dismal prognosis despite modern imaging techniques and aggressive surgical intervention. Identification of biologic markers for early diagnosis and improved therapeutic strategies is thus of paramount importance. S100P has been identified in a variety of malignant neoplasms of the gastrointestinal and pancreaticobiliary systems, but it is not yet known if S100P expression is associated with clinically-relevant characteristics of gall bladder carcinoma. The aims of the present study were: 1) to investigate the relationship between S100P expression and histological type, grade, tumor-node-metastasis stage, presence of vascular invasion, perineural invasion and necrosis; and 2) to evaluate for any S100P-defined difference in the risk for tumor recurrence or death. METHOD Immunostains for S100P were performed on 4 tissue microarray blocks containing 91 cases of gall bladder carcinoma. RESULT The intensity of S100P staining was significantly associated with pathological T stage 4 (p = 0. 0238). Staining intensity ≥3 in ≥25% tumor cells was associated with pathological T stage 4 (p = 0.0005). A higher S100P immunoreactivity score (IRS) was significantly associated with higher TNM stage (p = 0.0341). Age (p = 0.0485), presence of vascular invasion (p = 0.0359), pathological T stage (p = 0.0291) and TNM stage (p = 0.0153) were significantly associated with tumor recurrence. Intense S100P reactivity was associated with decreased overall survival [hazard ratio = 9.614; 95% confidence interval (CI), 1.873-49.338; p = 0.0067]. CONCLUSION Our findings indicate that S100P over-expression is a potential prognostic marker for gall bladder carcinoma and is significantly associated with advanced tumor stage and poorer survival.

Abstract
Gallbladder cancer (GBC) is an aggressive disease that shows evident geographic variation and is characterized by a poor prognosis, mainly due to the late diagnosis and ineffective treatment. Genetic variants associated with GBC susceptibility, including polymorphisms within the toll-like receptors TLR2 and TLR4, the cytochrome P450 1A1 (CYP1A1), and the ATP-binding cassette (ABC) transporter ABCG8 genes, represent promising biomarkers for the stratification of patients at higher risk of GBC; thus, showing potential to prioritize cholecystectomy, particularly considering that early diagnosis is difficult due to the absence of specific signs and symptoms. Similarly, our better understanding of the gallbladder carcinogenic processes has led to identify several cellular and molecular events that may influence patient management, including HER2 aberrations, high tumor mutational burden, microsatellite instability, among others. Despite these reports on interesting and promising markers for risk assessment, diagnosis, and prognosis; there is an unmet need for reliable and validated biomarkers that can improve the management of GBC patients and support clinical decision-making. This review article examines the most potentially significant biomarkers of susceptibility, diagnosis, prognosis, and therapy selection for GBC patients, highlighting the need to find and validate existing and new molecular biomarkers to improve patient outcomes.

Abstract
Adenosquamous carcinoma (ASC), containing both adenocarcinoma and squamous cell carcinoma components, is rare in the digestive system. Limited data is available on ASC of the digestive system (AS-ASC), and the current evidence is available mainly in the form of case reports and case series. We performed a thorough search of the available literature and compiled a review on the epidemiology, histopathology, pathogenesis, clinical manifestations, diagnosis, treatment, and prognosis of AS-ASC. Non-specific clinical and imaging presentations and low diagnostic accuracy of biopsy lead to difficulties in preoperative diagnosis in a high proportion of patients and high malignancy. The pathogenesis remains obscure. Surgery remains the mainstay of treatment for AS-ASC. The role of chemoradiotherapy as an adjuvant treatment is still inconclusive. Key messages Metastatic linings and the lack of efficacious treatments lead to an unfavorable outcome in AS-ASC patients. Further research could help us understand the pathophysiology of AS-ASCand the unique needs of AS-ASC patients.

Abstract
Background Gallbladder cancer (GBC) is the most common tumor of the biliary tract. The incidence of GBC shows a large geographic variability, being particularly frequent in Native American populations. In Chile, GBC represents the second cause of cancer-related death among women. We describe here the establishment of three novel cell lines derived from the ascitic fluid of a Chilean GBC patient, who presented 46% European, 36% Mapuche, 12% Aymara and 6% African ancestry. Results After immunocytochemical staining of the primary cell culture, we isolated and comprehensively characterized three independent clones (PUC-GBC1, PUC-GBC2 and PUC-GBC3) by short tandem repeat DNA profiling and RNA sequencing as well as karyotype, doubling time, chemosensitivity, in vitro migration capability and in vivo tumorigenicity assay. Primary culture cells showed high expression of CK7, CK19, CA 19-9, MUC1 and MUC16, and negative expression of mesothelial markers. The three isolated clones displayed an epithelial phenotype and an abnormal structure and number of chromosomes. RNA sequencing confirmed the increased expression of cytokeratin and mucin genes, and also of TP53 and ERBB2 with some differences among the three cells lines, and revealed a novel exonic mutation in NF1. The PUC-GBC3 clone was the most aggressive according to histopathological features and the tumorigenic capacity in NSG mice. Conclusions The first cell lines established from a Chilean GBC patient represent a new model for studying GBC in patients of Native American descent.

Abstract
Adenosquamous carcinoma (ASC) of the gallbladder is a rare malignant tumor that is characterized by a coexisting of glandular and squamous components. In a case of ASC, we performed hotspot multigene mutational profiling of 164 hotspot regions of eleven cancer-associated genes (AKT1, APC, BRAF, CTNNB1, KIT, KRAS, NRAS, PDGFRA, PIK3CA, PTEN and TP53) in the two microdissected components. Both tumor phenotypes resulted characterized by a p.E542K point mutation in the PIK3CA gene, whereas adenocarcinoma component revealed also a TP53 Q331* homozygous stop mutation. Of note, coexisting high-grade dysplastic epithelium was characterized by a mixed cell population, with an upper part featuring a glandular differentiation and a basal layer of p63 positive (squamous committed) cells. Overall these data provide evidence of an early squamous differentiation of the lesion with a common genetic landscape of the two components.

Abstract
Psoriasis vulgaris is a chronic inflammatory skin disease, stubbornly intractable, with substantial consequences for patient physical and mental welfare. Approaches currently available to treat psoriasis are not satisfactory due to undesirable side-effects or expense. Psoriasis is characterized by hyperproliferation and inflammation. Oxymatrine, an active component extracted from Sophora flavescens, has been demonstrated to possess anti-proliferation, anti-inflammatory, anti-tumorigenic, immune regulation and pro-apoptotic properties. This investigation presents a detailed retrospective review examining the effect of Oxymatrine on psoriasis and investigates the mechanisms underlying patient responses to Oxymatrine. We confirm that Oxymatrine administration significantly reduced the Psoriasis Area Severity Index score, with high efficacy compared to the control group. In addition, we have found that Oxymatrine significantly inhibits the viability, proliferation and differentiation of human keratinocyte in vitro. Immunohistochemical analysis indicates Oxymatrine significantly suppresses the expression of Pan-Cytokeratin, p63 and keratin 10. The results indicate that the suppression of p63 expression may lead to the anti-proliferation effect of Oxymatrine on human skin keratinocytes. Oxymatrine does not affect the formation of basement membrane, which is very important to maintain the normal function of human skin keratinocytes. In summary, Oxymatrine offers an effective, economical, and safe treatment for patients presenting with intractable psoriasis vulgaris.

[PMID: 24927072 DOI: 10.3892/or.2014.3267] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2014] [Accepted: 05/12/2014] [Indexed: 11/06/2022] Open
Abstract
Accumulating evidence indicates that cancer stem cells (CSCs) are involved in resistance to radiation therapy (RT). Bmi-1, a member of the Polycomb family of transcriptional repressors, is essential for maintaining the self-renewal abilities of stem cells and overexpression of Bmi-1 correlates with cancer therapy failure. Our previous study identified that the CD44+ nasopharyngeal cancer (NPC) cells may be assumed as one of markers of nasopharyngeal carcinoma cancer stem cell-like cells (CSC-LCs) and Bmi-1 is overexpressed in CD44+ NPC. In the present study, we used RNA interference technology to knock down the expression of Bmi-1 in CD44+ NPC cells, and then measured the radiation response by clonogenic cell survival assay. DNA repair was monitored by γH2AX foci formation. Bmi-1 downstream relative gene and protein expression of p16, p14, p53 were assessed by western blotting and real-time PCR. Cell cycle and apoptosis were detected by flow cytometry assays. We found that Bmi-1 knockdown prolonged G1 and enhanced the radiation-induced G2/M arrest, inhibited DNA damage repair, elevated protein p16, p14 and p53 expression, leading to increased apoptosis in the radiated CD44+ cells. These data suggest that Bmi-1 downregulation increases the radiosensitivity to CD44+ NPC CSC-LCs. Bmi-1 is a potential target for increasing the sensitivity of NPC CSCs to radiotherapy.
