Abstract
BACKGROUND/AIM We previously described four different vascular patterns (reticular, diffuse, fasciculate, and trabecular) in renal cell carcinoma (RCC) suggesting an early and heterogeneous acquisition of perivascular cells most probably due to a particular PDGF pathway gene expression profile. The aim of the study was to study PDGF pathway gene expression profiles, separately for each vascular pattern. MATERIALS AND METHODS TaqMan assay for the PDGF pathway was performed on twelve cases of ccRCC previously evaluated by histopathology, immunohistochemistry, and RNAscope. Gene expression profile was correlated with grade, invasion, vascular patterns, and VEGF. RESULTS PIK3C3 and SLC9A3 genes were overexpressed in all vascular patterns, but they were significantly correlated with high VEGF mRNA in the reticular and diffuse pattern. STAT1, JAK2, SHC2, SRF and CHUK (IKK) were exclusively overexpressed in cases with diffuse vascular pattern. SLC9A3, CHUK and STAT3 were overexpressed in G2 tumors. CONCLUSION Three ccRCC subgroups were defined: 1) PIK3C3 (VSP34)/SLC9A3 which may be proper for anti PIK3C3 inhibitors; 2) VEGFhigh subgroup where association of anti VEGF may be a benefit and 3) JAK2/STAT1 subgroup, potentially being eligible for anti JAK/STAT therapy associated with IKK inhibitors.

Abstract
BACKGROUND/AIM Angiogenic growth factors expression is not known in the normal cornea. The aim was to study corneal gene expression profile of VEGF and PDGF pathways influencing the avascular state of cornea. MATERIALS AND METHODS cDNA synthesis was performed from mRNA extracted from five fresh pig corneas followed by cDNA synthesis and analysis of VEGF and PDGF pathways by TaqMan Array gene expression profile. RESULTS Normal pig cornea lacks VEGFR2 and VEGFR3 gene expression. MK2 and AKT1 genes were significantly overexpressed (p=0.000684, p=0.050995, respectively). Six PDGF pathway genes were overexpressed: TIAM1 (p=0.047), PIK3CA (p=0.00005), IKBKG (p=0.000006), PAK4 (p=0.034), RAC1 (p=0.000006 and PTGS2, p=0.00375). PDGF A was up-regulated, but not with a statistical significance (p=0.79911), while PDGFRα was down-regulated and PDGFRβ was not expressed. CONCLUSION Normal cornea avascularity is given by growth factor receptors down-regulation. Rapid corneal neovascularisation is induced by activation of the main angiogenic growth factors that induce angiogenic cascade and vessel recruitment.

Abstract
BACKGROUND/AIM The histopathological variability of each type of pituitary adenoma (PA) that causes growth hormone (GH) excess influences the phenotype, radiological characteristics and therapy response of acromegaly patients. We correlated the immunohistochemical (IHC) features of GH-secreting PAs with their clinical, laboratory and imaging data. PATIENTS AND METHODS We included 32 patients with documented acromegaly; tumour specimens were histologically and IHC examined: anterior pituitary hormones, pituitary-specific transcription factor-1 (PIT-1), Ki-67 labelling index were evaluated. RESULTS Macroadenomas represented 93.75%. Post-surgery disease control negatively correlated with the maximum initial tumour diameter (p=0.04). Ki-67 did not predict remission. No correlation was found between GH serum levels and IHC expression (p=0.45). PIT-1 was positive in all specimens, two had a weak expression. Four were considered PIT-1 positive plurihormonal adenomas and several had unusual IHC combinations. CONCLUSION PIT-1 accurately classifies GH-secreting PAs. The IHC classification as well as radiological dimensions and extent influence disease control, probably being the best prognosis factors.

Abstract
BACKGROUND/AIM Chloride intracellular channel protein (CLIC1), E- and P-cadherin (Ecad, Pcad) are certified factors of aggressivity, but they have not been studied in breast cancer to date. The aim was to study CLIC1, Ecad and Pcad impact on breast cancer in terms of defining new high-risk subgroups. MATERIALS AND METHODS Ninety-seven breast cancer biopsies were immunohistochemically evaluated for CLIC1, Ecad and Pcad expression related to molecular subtypes. CLIC1 expression was assessed in both tumor cells (CLIC1T) and blood vessels (CLIC1V). RESULTS For 23% of Luminal A cases, both cadherins and CLIC1V were positive. Luminal B/HER2 subtype, had two specific phenotypes: Ecad-/Pcad-/CLIC1T-/CLIC1V+ and Ecad+/Pcad-/CLIC1T-/CLIC1V+. All TNBC cases were clustered into two subgroups: 60% were Ecad+/Pcad+/CLIC1T+/CLIC1V+) while 40% were Ecad+/Pcad+/CLIC1T+/CLIC1V-). CONCLUSION CLIC1, Ecad and Pcad association stratifies molecular types of breast cancer in subgroups that may explain different response to therapy and different aggressiveness previously observed by other authors within the same molecular subtype.

Abstract
BACKGROUND/AIM Human mesenchymal stem cells (hMSC) represent a versatile cell population, able to modulate the tumor microenvironment. Our aim was to recreate an open scene for the in vivo interaction between hMSC and the MCF-7 breast cancer cells (MCF-7), in order to enlighten the intimate involvement of hMSC in tumor vasculogenesis and angiogenesis. MATERIALS AND METHODS hMSC and MCF-7 were seeded onto the chick embryo chorioallantoic membrane (CAM) and incubated for 7 days. Consecutively, the morphology and the immunohistochemical profile of CAM were assessed. RESULTS Following this complex interaction, MCF-7 acquired a more aggressive phenotype, hMSC switched to a vascular precursor phenotype, while CAM underwent a major reset to an earlier stage, with hotspots of angiogenesis, vasculogenesis and hematopoiesis. CONCLUSION The hallmark of this study was the establishment of a veritable in vivo experimental model of MSC involvement in tumor vasculogenesis and angiogenesis, allowing further analysis in the field.

Abstract
BACKGROUND/AIM E- and P-cadherin (E-cadh, P-cadh) control tumor cell invasion, metastatic or stemness potential and chemotherapy resistance. The study aimed to assess E- and P-cadherin expression in breast cancer molecular subtypes. MATERIALS AND METHODS Immunohistochemistry for E-cadh and P-cadh was performed for 97 breast cancer cases. Membrane (M), cytoplasmic (C) or mixed (MC) patterns of E-cadh and P-cadh were considered in our evaluation. RESULTS E-cadh and P-cadh C pattern was significantly correlated in the HER2 subtype (p=0.031). P-cadh M pattern was highly specific for the HER2 subtype (p=0.002). Only P-cadh C characterized the triple negative breast cancer subtype (p=0.015). For Luminal B/HER2 cases, P-cadh M pattern was strongly coexpressed with the E-cadh MC pattern (p=0.012). Progesterone receptor (PR) expression influenced E-cadh M pattern in the Luminal B/HER2 subtype (p=0.042). CONCLUSION E- and P-cadherins define distinct subgroups within breast cancer molecular subtypes. Our findings support the inclusion of E- and P-cadherin into breast cancer molecular classification.

Abstract
BACKGROUND The role of podoplanin (PDPN) and homebox prospero gene 1 (PROX1) in early stages of pancreatic islet changes induced by hypercaloric diet is unclear. The aim of this study was to study PDPN and PROX1 variability in pancreatic islets after a hypercaloric diet in a rat experimental model. MATERIALS AND METHODS Pancreatic biopsies harvested from Sprague-Dawley rats at 3, 6, and 9 weeks following hypercaloric diet intake were evaluated for morphological and molecular changes of Langerhans islets based on PDPN and PROX1 expression Results: Six weeks of hypercaloric diet induced hypertrophy of pancreatic islets with focal expression of Pdpn and Prox1 mRNA. At 9 weeks of hypercaloric diet, strong peri-insular inflammation was found around hypertrophic islets highly expressing PDPN, and lacking Prox1 mRNA and protein expression. CONCLUSION This is the first report of Pdpn and Prox1 mRNA expression variability and involvement in early steps of pancreatic islet changes following hypercaloric food intake.

Abstract
BACKGROUND/AIM Chloride intracellular channel 1 (CLIC1) represents a promising target for personalized therapy. Our aim was to assess CLIC1 expression in clear cell renal cell carcinoma (cc RCC) and identify its possible prognostic role. MATERIALS AND METHODS Fifty cases of cc RCC were evaluated and selected for immunohistochemistry. CLIC1 expression was correlated with tumor grade, invasion and heterogeneity. RESULTS A total of 87.5% of the cases were CLIC1 positive, with either a homogeneous (31.42%) or a heterogeneous (68.57%) pattern. Low, mild and strong CLIC1 expressing tumors were defined based on nuclear (N), cytoplasmic (C), membrane (M) or combinations of them (NC, NM, CM, NCM) in terms of CLIC1 distribution. A significant correlation was found between tumor grade and percent of positive tumor cells (p=0.017). For G3 tumors, CLIC1 cytoplasmic expression was strongly correlated with high expression status (p=0.025) and tumor heterogeneity (p=0.004). CLIC1 expression was also correlated with metastasis (p=0.046). CONCLUSION We defined four cc RCC groups depending on G, CLIC1 expression and pattern: i) G3/NM/low CLIC1+, ii) G2/CM/mild CLIC1+ iii) G1 or G2/NM or CM /high CLIC1+, and iv) G2/M /high CLIC1.

Abstract
BACKGROUND/AIM Chemotherapy-induced cardiotoxicity may be observed during treatment or may cause severe cardiac failure as the main cause of death, even several years after therapy implementation. Herein, the aim was to establish the early diagnosis of cardiotoxicity through the periodic evaluation of the left ventricular (LV) and vascular remodeling parameters, in patients with acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS The study population included 35 patients diagnosed with ALL, evaluated before and 3 months after starting chemotherapy, measuring systolic and diastolic parameters of the LV and intima-media thickness (IMT), arterial stiffness aortic pulse wave velocity (PWVAo) and ankle-brachial index (ABI). RESULTS After the first 2 cycles of chemotherapy, all patients experienced a drop in LV ejection fraction (LVEF) (p<0.001), and 12 patients suffered a decrease of LVEF<50%. The ABI (p<0.05) and the global longitudinal strain (GLS) (p<0.001) decreased, while IMT and PWVAo (p<0.001) increased, proving a subclinical deterioration of the LV function and vascular remodeling. CONCLUSION Assessment of cardiovascular risk factors before chemotherapy initiation in ALL patients may be helpful for an early diagnosis of chemotherapy-induced cardiotoxicity, thus contributing to early treatment and a subsequent decrease of death caused by such cardiovascular complications.

Abstract
BACKGROUND/AIM Mast cells (MCs) represent the most controversial non-malignant element of the tumor microenvironment. Our aim was to study how MCs density and distribution (intratumoral-MCit versus peritumoral-MCpt) relate to tumor grade and molecular subtypes. MATERIALS AND METHODS MCs tryptase immunohistochemistry was performed on 80 cases of breast carcinomas. RESULTS For Luminal A tumors, a partial correlation was detected between MCit and progesterone receptor (PR) (p=0.005). Luminal B tumors showed a significant correlation between MCpt and age (p=0.009), estrogen receptor (ER) (p=0.017) and PR (p=0.035). MCit and MCpt were strongly interrelated in this subtype (p=0.002) and in triple-negative breast cancers (p=0.002). In HER2 subtype, MCpt tumors were significantly correlated with HER2 (p=0.044). In G2 tumors, MCpt correlated with ER (p=0.015) and PR (p=0.038) while in G3 tumors ER correlated with both MCit (p=0.009) and MCpt (p=0.000487) tumors. CONCLUSION MCs dynamics are strongly influenced by hormone receptors and HER2 status. MCit increased in aggressive tumor types and is a worse prognostic factor.

Abstract
BACKGROUND/AIM The aim of this study was to evaluate SOX2 expression in pituitary adenomas and its correlation to their secretory state and clinicopathological parameters. PATIENTS AND METHODS Thirty-four patients were clinically evaluated and surgery was recommended for tumor removal. Histopathological diagnosis by hematoxylin eosin staining was followed by immunohistochemistry for pituitary hormones and SOX2 co-expression. RESULTS Fourteen of the 34 cases were GH-secreting adenomas, 10 were prolactinomas and 10 non-functioning pituitary adenomas. SOX2-positive expression was detected in 47.05% of total cases: 8 GH-secreting adenomas (57.14%), 6 prolactinomas (60%) and 2 non-functioning adenomas (20%). SOX2 positivity was significantly higher amongst secreting adenomas (p=0.041). SOX2-negative tumors were significantly associated with corticotrophin deficiency (p=0.047) and gonadotrophin deficiency (p=0.041). No correlation with tumor size or extrasellar extension was detected. CONCLUSION SOX2 is differentially expressed in pituitary adenomas and influences the secretory state or clinical behavior of pituitary adenomas.

Abstract
Vascular endothelial growth factor (VEGF), its inhibitory splice variant, VEGF165b and Endocrine Gland derived VEGF (EG-VEGF) have a controversial role in pituitary gland. We aim to study VEGF, VEGF165b and EG-VEGF expression in pituitary adenomas. A significant correlation was found between growth hormone (GH) and VEGF secretion (P=0.024). For prolactinomas, VEGF and prolactin expression, had a P-value of 0.02 for Kendall coefficient and a P-value of 0.043 for the Spearman coefficient. VEGFmRNA amplification was detected in both tumor cells and folliculostellate cells. VEGF165b was positive in 16.66% of pituitary adenomas. EG-VEGF was significantly correlated with prolactin (P=0.025) and luteinizing hormone (P=0.028). Our data strongly support VEGF, VEGF165b and EG-VEGF as important players of pituitary adenomas tumorigenesis. Particular hormonal milieu heterogeneity, special vascular network with an unusual reactivity to tumor growth correlated with variability of VEGF, VEGF165b and EG-VEGF secretion may stratify pituitary adenomas in several molecular groups with a direct impact on therapy and prognosis.

Hyaluronic Acid/Bone Substitute Complex Implanted on Chick Embryo Chorioallantoic Membrane Induces Osteoblastic Differentiation and Angiogenesis, but not Inflammation. Int J Mol Sci 2018; 19:ijms19124119.

Abstract
Microscopic and molecular events related to alveolar ridge augmentation are less known because of the lack of experimental models and limited molecular markers used to evaluate this process. We propose here the chick embryo chorioallantoic membrane (CAM) as an in vivo model to study the interaction between CAM and bone substitutes (B) combined with hyaluronic acid (BH), saline solution (BHS and BS, respectively), or both, aiming to point out the microscopic and molecular events assessed by Runt-related transcription factor 2 (RUNX 2), osteonectin (SPARC), and Bone Morphogenic Protein 4 (BMP4). The BH complex induced osteoprogenitor and osteoblastic differentiation of CAM mesenchymal cells, certified by the RUNX2 +, BMP4 +, and SPARC + phenotypes capable of bone matrix synthesis and mineralization. A strong angiogenic response without inflammation was detected on microscopic specimens of the BH combination compared with an inflammatory induced angiogenesis for the BS and BHS combinations. A multilayered organization of the BH complex grafted on CAM was detected with a differential expression of RUNX2, BMP4, and SPARC. The BH complex induced CAM mesenchymal cells differentiation through osteoblastic lineage with a sustained angiogenic response not related with inflammation. Thus, bone granules resuspended in hyaluronic acid seem to be the best combination for a proper non-inflammatory response in alveolar ridge augmentation. The CAM model allows us to assess the early events of the bone substitutes–mesenchymal cells interaction related to osteoblastic differentiation, an important step in alveolar ridge augmentation.

Abstract
Aim To assess the onset of early left ventricular (LV) systolic and diastolic function impairment and the subclinical atherosclerosis following chemotherapy in patients diagnosed with acute myeloid leukemia (AML). MATERIALS AND METHODS Thirty patients diagnosed with AML with no cardiac history, having LV ejection fraction (LVEF) >50%, were evaluated at baseline and 6 months after starting four cycles of chemotherapy. We measured LV function, global longitudinal strain and subclinical atherosclerosis markers: intima-media thickness (IMT), arterial stiffness aortic pulse wave velocity (PWVAo) and ankle-brachial index (ABI). RESULTS LVEF had decreased at 6 months after treatment initialization (p<0.001), the same changes being observed for LV fraction shortening (p<0.001), mitral annular plane systolic excursion and S' wave (p<0.001 and p<0.05). Bilateral IMT and PWVAo significantly increased, 12 out of 30 patients (40%) had LVEF ≤50% after 6 months of chemotherapy, five of them receiving daunorubicin at more than 500 mg/m2/injection. CONCLUSION LV function is impaired after 6 months of chemotherapy, with early changes of subclinical atherosclerosis becoming evident.

Abstract
PDGFs/PDGFRs axis is documented as an important tumor-promoting agent and potential therapeutic target for several human carcinomas, including breast cancer. However, little is known about the role played by the PDGF family members in the normal development of the breast tissue, breast carcinogenesis and tumor-microenvironment dynamics Despite its potent pro-lymphangiogenic effects, PDGF-B/PDGFR-beta axis remains controversial and incompletely elucidated in the field of breast cancer, with emphasis to its differential implications in breast cancer molecular subtypes. Although some data are available concerning this aspect, little or no information is found regarding the role of the PDGF-B/PDGFR-beta axis in rare and aggressive types of breast cancers, such as triple negative breast cancers (TNBCs) and its associated subtypes This review attempted to gather as many data as possible concerning PDGFs family members in the normal breast tissue and in breast carcinogenesis with special focus on their role in diagnosis and therapeutic approach.

Abstract
AIM To characterize baby hamster kidney fibroblast (BHK 21/C13) cells and test the effects of antibodies against podoplanin and disodium cromolyn on BHK 21/C13 cell line-derived tumors grown on chick embryo chorioallantoic membrane (CAM). MATERIAL AND METHODS BHK 21/C13 cell-derived fibrosarcomas developed in hamsters were implanted on CAM and treated with anti-podoplanin antibodies and disodium cromolyn. BHK 21/C13 cell immunophenotype was assessed. RESULTS Fibrosarcoma cells were positive for vimentin, CD117, smooth muscle actin, vascular endothelial growth factor epidermal growth factor receptor, homebox prospero gene 1 and negative for platelet-derived growth factor B, neuron-specific enolase, S100, CD34, Ewing sarcoma and podoplanin. CAM-grown fibrosarcomas were highly sensitive to disodium cromolyn and anti-podoplanin antibodies. CONCLUSION Immunophenotyping BHK 21/C13 cells and their response to drugs represent the first step in revealing cell line utility and a reliable tool for experimental cancer research.

Abstract
BACKGROUND Few data are available regarding the epithelial to mesenchymal transition (EMT) /mesenchymal to epitheilal transition (MET) in the liver metastasis of digestive cancers. The aim of this study was to establish EMT/MET metastatic tumor cell plasticity according to the histological growth pattern of liver metastases. MATERIALS AND METHODS Biopsies from 25 patients with liver metastasis (desmoplastic, replacement and pushing type) were evaluated. Double immunostaining of E-cadherin/vimentin, keratin 8,18/vimentin and E-cadherin/ keratin 8,18 were performed. RESULTS The following cell types were noted: epithelial, mesenchymal, non-differentiated and differentiated hybrid mesenchymal/ epithelial and non-hybrid phenotype. All cases had mesenchymal/ epithelial phenotype cells. A significant correlation was found between the non-differentiated hybrid mesenchymal/ epithelial phenotype metastatic cells and histological growth pattern for gastric and colorectal cancer. CONCLUSION A MET-targeting strategy, in conjunction with conventional chemotherapy, may be useful for the treatment of liver metastases.

Abstract
In children, lymphangiomas are extremely rare pathologic entities that are characterized by unusual locations. The mesenteric localization is extremely rare in children, and the clinical signs usually mimic an acute abdominal syndrome. For most of the cases, their diagnosis is established by the radiologist, and the main therapeutic option is represented by surgery for lesion removal. We hereby describe the case of a 4 year old girl admitted to the pediatric emergency department for continuous abdominal pain, more intense in the orthostatic position, associated with abdominal distension, nausea, and vomiting. These symptoms raised the clinical suspicion of acute abdominal syndrome. The patient had no previous clinically significant events. Radiologic examination suggested a mesenteric multicystic lymphangioma certified by surgical and histopathological evaluation. No specific targeted therapy is currently available; moreover, no specific criteria for recurrences have been stated. A new approach of infantile lymphangiomas following surgery, regarding the use of specific lymphatic markers panel including D2-40, Prox-1, VEGFR-3, PDGFs, and Ki67 may improve the characterization of such lesions regarding their prognosis, recurrence rate and targeted therapy implementation especially for those with a more aggressive or recurrent behavior.

Abstract
BACKGROUND/AIM To analyze the interaction between the human mesenchymal stem cells (hMSC) and the chick embryo chorioallantoic membrane (CAM), in order to assess the still obscure process of vasculogenesis. MATERIALS AND METHODS We implanted hMSC onto CAM and we analyzed the morphology and the immunohistochemical profile of CAM. RESULTS hMSC adhered to CAM, few of them entered the chorionic epithelium and the mesoderm and developed a CD44-/Ki67- status. hMSC stimulated the CAM mesenchymal cells (cMSC) to acquire endothelial and pericyte-like features and to generate cord/capillary-like structures (CLS) in the chorionic epithelium and the mesoderm, but they also entered these structures (CD34+/SMA (smooth muscle actin)+ hMSC). Simultaneously, hMSC induced a process of sprouting angiogenesis in the mesoderm, CD105+ hMSC being identified in the proximity of the angiogenic areas. CONCLUSION hMSC and CAM establish a genuine hotspot of vasculogenesis, which may evolve to a valuable experimental model for this research field.

Abstract
BACKGROUND/AIM To assess the concordance between IHC and FISH and its influence on tumor type, grade and lympho-vascular invasion (LVI). MATERIALS AND METHODS HER2 immunohistochemistry (IHC) to 45 cases of bladder carcinoma, followed by fluorescent in situ hybridization (FISH) were applied. RESULTS 31.12% cases were IHC positive. Less than 35% of HER2-negative cases presented LVI and this percent increased to 54.54% for +1 HER2 cases. LVI increases up to 57.14% for +2 HER2 cases and slightly decreased for +3 HER2 cases to 42.85%. IHC/FISH concordance was found for 73.34% cases but 31.57% were previously negative and 36.36% scored as +1 by IHC had gene amplification as shown by FISH analysis. T3 was correlated with HER2-IHC (p=0.05) and HER2-FISH (p=0.01). CONCLUSION Improved HER2 assessement is needed for urothelial carcinomas. HER2-IHC scored as 0-2 should be validated by and reclassified according to FISH analysis.

Abstract
The true onset of atherosclerosis remains one of the biggest challenges for cardiologists. Is atheroma plaque development considered the earliest step of vascular aging? If so, when it starts? Before or after birth? If it starts before birth or early during childhood, it seems that Thomas Sydenham was right: "A man is as old as his arteries." Except disorganization of elastic fibers, less is known about the morphology of vascular aging and also about the molecular events influencing the age of arteries, arterial stiffness, and their role in the appearance of future complications. Cellular and molecular events responsible for the switch from physiologic to pathologic aging of human arteries are less known. Epigenetic, genetic, and environmental influences at the onset of early vascular aging (EVA) should specifically influence the process. This paper briefly reviews the controversial data regarding vascular aging with an emphasis on the less known facts about the morphology of EVA.

Abstract
One of the most controversial women malignancies, triple negative breast cancers (TNBCs) are critically overviewed here, being focused on data useful in clinical practice or to improve the therapy and patients survival. TNBCs "choose" young women and its "kiss" is, unfortunately deadly in most cases. Currently, few sparse data are available in literature concerning the origins of TNBC. Vasculogenic mimicry detected in TNBCs, seems to be determined by a population of CD133+ cells and may be stimulated by different pharmacological agents such sunitinib. Despite the fact that TNBCs do not usually metastasize through the lymphatic pathways, TNBCs may be characterized by lymphatic invasion and by an increased lymphatic microvascular density. If TNBCs treatment depends on the molecular profile of the tumor, the same statement may be postulated for TNBCs metastasis. Whether metastases have a similar phenotype as the primary tumor remains an enigma. Therefore, the question: 'Could TNBC be subject to a standardized, unanimously accepted therapeutic strategy or is it strictly subclass-dependent?' remains to be further investigated.

ENDOKRYNOLOGIA POLSKA 2017; 68:380-389.

Abstract
INTRODUCTION S100 protein and GFAP expression in pituitary adenomas tumour cells is not well known; few correlations with other prognostic or therapeutic factors have previously been reported in pituitary adenomas. We aim to elucidate their involvement in the pathogenesis of pituitary adenomas and to establish the correlation of their expression with different growth factors and growth factor receptors known to have a prognostic and/or therapeutic role. MATERIAL AND METHODS Sixty-one cases of pituitary adenomas were immunohistochemically assessed for the expression of GFAP and S100 protein in both tumour cells and FS cells, in close relationship with hormone profile, and correlated with vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) expression, previously studied by our team. RESULTS GFAP and S100 protein were expressed both in tumour cells and FS cells. Differences between morphology, distribution, and density of GFAP+ FS cells and S100+ FS cells were observed according to the hormone profile of pituitary adenomas. GFAP and S100 protein expression in tumour cells was significantly related to hormone profile of pituitary adenomas and also with VEGF and EGFR expression. CONCLUSIONS GFAP and S100 protein expressions in tumour cells from pituitary adenomas are influenced by hormone profile. Our re-sults support the presence of two molecular subtypes of FS cells GFAP+/VEGF+/S100 respectively and another one that is GFAP-/S100+/EGFR+ simultaneously with the classical variant GFAP+/S100+. It is possible that S100+/EGFR+ pituitary adenomas represent a group of pituitary adenomas with an aggressive behaviour and a high ability of invasion and recurrence.
