Abstract
INTRODUCTION Prognostic and predictive value of PD-L1 as a biomarker in breast cancer remains controversial. While some studies suggest its association with negative prognostic parameters, others reported a highly significant association between PD-L1 expression and tumor-infiltrating lymphocytes, which are known to be an independent favorable prognostic factor. The aim of present study is to examine the relationship between immune response markers and PD-L1 expression in early breast cancer. MATERIAL AND METHODS Immunohistochemical expression of PD-L1, along with density and composition of stromal lymphocytic infiltrate and peritumoral lymphoid aggregates was analyzed in 95 samples of invasive breast cancer. RESULTS A strong positive correlation between PD-L1 expression and the density of stromal lymphocytic infiltrate and peritumoral lymphoid aggregates was identified and a cut-off value of 53% coverage of tumor stroma by lymphocytes, with which PD-L1 positivity can be predicted with excellent diagnostic accuracy, was determined for the first time using statistical methods. Additionally, PD-L1 positivity was observed significantly more often in tumors with higher absolute number of both CD4 and CD8 T-lymphocytes in the stromal infiltrate. No significant correlation with molecular subtype of breast cancer was found. CONCLUSIONS Our results indicate that the density of stromal lymphocytic infiltrate might be a better predictor of PD-L1 positivity in early breast cancer than the molecular subtype and that the key to the optimization of PD-L1 as a biomarker in breast cancer lies in its interpretation in the context of other immune response markers.

Abstract
Despite recent advances in diagnosis and treatment, colorectal cancer (CRC) remains the third most common cancer worldwide, and has both a poor prognosis and a high recurrence rate, thus indicating the need for new, sensitive and specific biomarkers. MicroRNAs (miRNAs/miRs) are important regulators of gene expression, which are involved in numerous biological processes implicated in tumorigenesis. The objective of the present study was to investigate the expression of miRNAs in plasma and tissue samples from patients with CRC, and to examine their potential as CRC biomarkers. Using reverse transcription-quantitative PCR, it was revealed that miR-29a, miR-101, miR-125b, miR-146a and miR-155 were dysregulated in the formalin-fixed paraffin-embedded tissues of patients with CRC, compared with the surrounding healthy tissue, and these miRNAs were associated with several pathological features of the tumor. Bioinformatics analysis of overlapping target genes identified AGE-RAGE signaling as a putative joint regulatory pathway. miR-146a was also upregulated in the plasma of patients with CRC, compared with the healthy control group, and had a fair discriminatory power (area under the curve, 0.7006), with 66.7% sensitivity and 77.8% specificity. To the best of our knowledge, this distinct five-miRNA deregulation pattern in tumor tissue, and upregulation of plasma miR-146a, were shown for the first time in patients with CRC; however, studies on larger patient cohorts are warranted to confirm their potential to be used as CRC diagnostic biomarkers.

Abstract
The relationship between diabetes mellitus (DM) and pancreatic cancer is complex-DM is both a risk factor and early sign of pancreatic cancer. DM is a risk factor for pancreatic cancer because it increases insulin resistance, intrapancreatic concentrations of insulin, and the bioavailability of IGF, subsequently promoting ductal cell proliferation. Accordingly, treatment targeting the insulin/IGF pathway is the focus of many researchers. Antidiabetic drugs modify the risk for pancreatic cancer-metformin's antineoplastic effect being most notable and indicating potential clinical use in pancreatic cancer. New-onset DM can also be the first manifestation of pancreatic cancer. There are several theories for the pathogenesis of DM in pancreatic cancer, the most important being that DM is a paraneoplastic syndrome caused by diabetogenic factors. As a consequence of this intricate relationship, new-onset DM after the age of 50 is considered a red flag for pancreatic cancer, prompting the need for screening in this patient population. Multiple clinical studies are currently underway exploring this matter. A better understanding of the relationship between DM and pancreatic cancer could aid in developing novel screening and treatment strategies for pancreatic cancer. This could ultimately improve the prognosis and quality of life of patients with pancreatic cancer.

Abstract
Background/Aim: Many studies confirmed strong association between oncogenic genotypes of Human Papillomaviruses (HPVs) and some oropharyngeal and oral squamous cell carcinomas (OSCCs). The aim of this study was to determine the prognostic significance of HPV16 infection in OSCC in population of Montenegro i.e. correlation between HPV16 infection and disease free interval (DFI), disease recurrence and metastasis occurrence. Material and Methods: We examined surgically obtained specimens from 60 patients with OSCC (localized on the lower lip, tongue or/and floor of the mouth) in six years period. Tumor tissue samples were used for histological analysis and HPV16 genome PCR detection (primers for detection of E6 gene). Patients were followed up for the 3 years. Results: HPV16 infection was more commonly detected in females with OSCC (p=0.038), while no correlation between this infection and disease recurrence (p= 0.122) and/or metastasis occurrence (p= 0.934) was found. DFI was not significantly different between patients with or without HPV16 infection (p= 0.427), but DFI was significantly shorter (p= 0.003) in females with oral HPV16 infection compared to male patients with this infection. Conclusions: Counting that HPV16 infection has a negative prognostic significance in OSCC, the HPV immunization program against genital HPV infection, would also have a positive impact on the frequency of HPV-mediated OSCC in Montenegrin population.

Abstract
INTRODUCTION Incidentally discovered lung nodules can be worrisome for both the patient and their physicians. Although 95% of solitary lung nodules are benign, it is important to distinguish which nodules have high clinical suspicion for malignancy. Existing clinical guidelines do not apply to patients with signs and symptoms related to the lesion and with an increased baseline risk of lung cancer or metastasis. This paper highlights the vital role of pathohistological analysis and immunohistochemistry in the definitive diagnosis of such incidentally discovered lung nodules. MATERIAL AND METHODS The three cases presented were selected based on their similar clinical presentations. A review of the literature was performed using the online database PubMed, for articles published in the period between January of 1973 to February of 2023 using the following medical subject headlines: "primary alveolar adenoma," "alveolar adenoma," "primary pulmonary meningioma," "pulmonary meningioma," and "pulmonary benign metastasizing leiomyoma." Results (Case Series). The case series consists of three incidentally discovered lung nodule(s). Although they presented with high clinical suspicion for malignancy, detailed workup confirmed the diagnosis of three rare benign lung tumours: primary alveolar adenoma, primary pulmonary meningioma, and benign metastasizing leiomyoma. CONCLUSIONS Clinical suspicion for malignancy in the presented cases arose from previous and current medical history of malignancy, family history of malignancy, and/or specific radiographic findings. This paper highlights the need for a multidisciplinary approach in the management of incidentally discovered pulmonary nodules. Excisional biopsy and pathohistological analysis remain the gold standard in confirming the presence of a pathologic process and determining the nature of the disease. Common features of the diagnostic algorithm utilized among the three cases include multi-slice computerized tomography, excisional biopsy via atypical wedge resection (if the nodule is peripherally located), and lastly, pathomorphological analysis using haematoxylin and eosin staining and immunohistochemistry.

Abstract
Abstract
Oral squamous cell carcinoma (OSCC) makes 85–95% of all malignances in the oral cavity. Increasing evidence shows that the Human Papillomaviruses (HPVs) are preferentially associated with some oropharyngeal and OSCCs, namely the genotype 16. The aim of the present study was to determine the prevalence and clinical implications of HPV16 infection in oral squamous cell carcinoma in population of Montenegro.
This study included 60 patients with OSCC (localized on the lower lip, tongue or/and floor of the mouth), surgically treated at the Clinical Centre of Montenegro from 2012 to 2018. Surgically obtained formalin-fixed and paraffin-embedded specimens were used for histopathological analysis and HPV16 genome detection using standard Polymerase Chain Reaction (primers for detection of E6 gene). Each individual was further followed up for the period of three years and for different clinico-pathological characteristics, including disease free interval (DFI).
The prevalence of HPV16 infection in OSCCs was 23.3% and the infection was significantly more common in female patients (P = 0.038). No significant correlation was detectable between HPV16 infection and the patients' age (P = 0.302), tumor site (P = 0.125), tumor grade (P = 0.363) and disease stage (P = 0.995). Observing the total sample the DFI was not significantly different for HPV16-positive versus HPV16-negative patients (P = 0.427), but a gender-based difference in DFI was observed, with the significantly shorter DFI (Log Rank test, P = 0.003) in HPV16 positive female patients compared to male patients (P = 0.003).
The results obtained in this study provide scientific evidence for the development of national HPV vaccination program in Montenegro.

Abstract
Ovarian fibromas are benign tumors that consist of spindle cells in bundles or storiformly arranged with collagen fibers in the stroma. Thecomas resemble theca interna ovarian cells, and there is lipid material in their cytoplasm. There is an overlap in histological and immunohistochemical characteristics of these two benign tumors, and the term "fibrothecoma" was coined to describe such cases. Their incidence is extremely rare in adolescents. The subject of our study is a 15-year-old, unmarried, virgo intacta patient who was referred to us due to profuse vaginal bleeding and the loss of consciousness. A right ovary ultrasound examination exposed the formation of a hyperechoic tumor with a diameter of 41.2 mm × 29.5 mm. Findings of cancer antigen 125 (CA 125) in the amounts of 621.1 U/mL and 142.87 mIU/mL of the B-human chorionic gonadotropin (B-hCG) serum were determined. After preoperative preparation, we operated on the patient to remove a tumor with a diameter of 37 mm × 30 mm × 22 mm, smooth outer surface, solid cross-section, and yellowish white color. The diagnosis of fibrothecoma was made based on pathohistological examination. An unusual finding of fibrothecoma in a virgo intacta adolescent with profuse vaginal bleeding and increased levels of CA 125 and B-hCG may serve as a basis for broader thinking about the pathology of juvenile bleeding.

Abstract
BACKGROUND Discordant results exist about the role of human epidermal growth factor receptor 2 (HER2) overexpression and/or HER2 amplification in lung adenocarcinoma. We aimed to compare the performance of HercepTest and PATHWAY anti-HER2 (4B5) by correlating immunohistochemistry (IHC) results with silver in situ hybridization (SISH) in adenocarcinoma lung specimens. METHODS A total of 148 surgically resected adenocarcinoma lung specimens were included. RESULTS HER2 overexpression was found in 7.4% patients for HercepTest Dako and in 2.7% patients for 4B5 antibody. The overall coincidence between these two types of antibodies equals 93.9%. The incidence of HER2 amplification in lung adenocarcinoma was 17.6%, of which in 2.7% of the cases high-grade amplification was present. HER2 amplification was present in 90.9% of patients with overexpression of HER2, obtained by using HercepTest Dako and 75% patients using 4B5 antibody. A significant correlation between overexpression of HER2 receptors obtained by HercepTest Dako and 4B5 antibody and HER2 amplification was shown. CONCLUSION The research of the efficiency of targeted molecular therapies with an HER2 antibody may serve as a basis for the introduction of routine HER2 status determination in lung adenocarcinoma, dictating the need for the standardized protocol for HER2 status determination in such pathology.

Abstract
BACKGROUND Chondrosarcomas of the larynx are malignant tumours that most commonly originate from the hyaline cartilage. Chondrosarcoma of the larynx, the most common type of low-grade tumour, accounts for 1% of all laryngeal neoplasms.
CASE SUMMARY We present the case of a 60-year-old female patient who developed progressive hoarseness and shortness of breath over a 2-mo period. The patient had undergone resection of a laryngeal tumour 14 years before the aforementioned symptoms occurred, and histopathological analysis indicated that it was a chondroma. During the assessment of the patient, a submucosal, oval-shaped tumour was detected that was predominantly located on the left side of the larynx and was approximately 6 cm in size. The decision to perform left partial vertical laryngectomy was made. A pathohistological diagnosis of low-grade chondrosarcoma was made. Considering the results of pathohistological analysis and the positive margins of the resection, a total laryngectomy was performed. During the 12-mo follow-up, no local relapse or regional or distant metastases was detected.
CONCLUSION Chondrosarcoma of the larynx must be considered in the differential diagnosis of laryngeal submucosal tumours. It is crucial to carefully sample of tumour tissue, differentiate chondroma and chondrosarcoma, and consider the possibility of malignant changes from chondroma to chondrosarcoma.

Abstract
Background During embryonic development in women, a regression of temporary embryonic structures – mesonephric (Wolffian) ducts occurs. Adnexal tumors of Wolffian duct origin (FATWO) are rare. Case report We presented the case of a 64-year-old female patient who was diagnosed with FATWO. After the surgical treatment, the uterus with bilateral adnexal structures was submitted for histopathological analysis. The left ovary was occupied by a tumor measuring 80 × 60 × 50 mm, with smooth, shiny, whitish surface. Tumor cells were medium-sized, relatively uniform, round, and polygonal, with eosinophilic cytoplasm and centrally laid nucleus with fine chromatin, organized into solid, trabecular, and tubular formations. Tumor cells were positive for pancytokeratin (CK), CK7, CD10, neuron-specific enolase (NSE), synaptophysin, calretinin, progesterone, estrogen, and epithelial membrane antigen (EMA). Conclusion This case adds a report of a rare tumor to the literature. We must think of it in the differential diagnostic algorithm to make an accurate diagnosis for selecting the best treatment modality.

Abstract
Triple negative breast cancer (TNBC) account for 12% to 17% of all breast cancers. It is a heterogeneous group of tumors associated with aggressive clinical course. Insulin-like growth factor II mRNA binding protein 3 (IMP3) belongs to a family of insulin-like growth factor type II (IGF2), which plays a key role in the transmission and stabilization of mRNA, cell growth, and migration during embryogenesis. Increased expression of IMP3 is associated with aggressive behavior of different tumor types, advanced clinical stage, distant metastasis, and shorter overall survival (OS).The study included 118 patients with breast carcinoma diagnosed as TNBC and immunohistochemical staining for estrogen receptors (ER), progesterone receptors (PR), epidermal growth factor receptor 2 (HER2/neu), Ki-67, and IMP3 was performed. Correlations between categorical variables were studied using the chi-square and the Mann-Whitney U test. For survival analysis, the Kaplan-Meier method, log-rank test and the Cox proportional hazard regression model were used.Positive expression of IMP3 protein was present in 35.6% of TNBC. The presence of basal morphology was observed in 46.6% of TNBC. Positive IMP3 expression was connected with larger size of tumor, higher clinical stage, and basal morphology (P = .039, P = .034, P < .001). Disease-free survival and OS were significantly shorter in IMP3 positive TNBC.According to results of our study IMP3 expression can be used as negative prognostic factor for triple negative breast carcinomas. Targeting IMP3 molecule could be an effective approach to the management of a triple negative breast cancer with new immunological therapies, which does not yet exist for this group of tumors.

Abstract
The aim of this study was to examine the spatio-temporal appearance of different neuronal cell subtypes by analyzing expression patterns of several neuronal markers (calretinin, neurofilament 200 (NF200), vanilloid receptor 1(VR1) and calcitonin gene-related peptide (CGRP)) of the embryonic human spinal cord (SC). Developing human SCs from 11 human conceptuses beetwen 5-10 developmental weeks (DW) were examined by light and electron microscopy and immunofluorescence. Light and electron microscopy revealed different embryonic stages of recognizable structure of the SC. NF200, CGRP and VR1 positive cells were observed in SCs during 5th-6th DW. NF200 was predominantly expressed in the ventral part, indicating presence of motoneurons. As development advanced, NF200 was mainly expressed in the marginal zone. Expression of CGRP was intense during all of the investigated periods, predominantly during the 5th-6th DW pointing to neural sensory differentiation, as opposed to the last DW when reduced expression of CGRP in the marginal layer indicated the terminations of the sensory afferents. Expression of VR1 was highest in the intermediate zone, at the beginning and at the end of the investigated periods, pointing to VR1 spatial pattern in the visceral afferents in the grey matter, while the first signs of calretinin were found in the 9th-10th DW ventrally. Delineating the relationships between factors involved in processes of neuronal differentiation as well as spatial and temporal arrangement of SC interrelated neurons can provide a useful information about normal SC development as well as the insight in possible causes of anomalies and disorders during embryonic life.

Abstract
The common femoral artery (CFA) divides into the superficial femoral artery (SFA) and deep femoral artery (DFA). The lateral circumflex femoral artery (LCFA) and medial circumflex femoral artery (MCFA) are most often branches of the DFA, although a large number of different variations in their origin has been described. We performed microdissection on both lower limbs of 30 fetuses, gestational age from 7 to 10 lunar months. Our results show that the LCFA and MCFA usually arise from the DFA. In 78.3% of cases, the MCFA originated from the DFA. In 11.7% of cases, the MCFA originated from the CFA, and in 5% of cases from the SFA. One case showed a common trunk with the DFA. Also, the MCFA was missing in one case, and it had a common trunk with the LCFA in one case. In 83.3% of cases, the LCFA arose from the DFA and in 6.7% of cases from the CFA. In one case, it had a common trunk with the DFA, and in one case with the MCFA. In 3.3% of cases, the LCFA was missing. In 66.7% of cases, both arteries originated from the DFA, in 15% of cases one originated from the DFA and the other from the CFA or SFA. Our results are in accordance with some published studies but also differ from the outcomes of other studies. Comprehensive knowledge of different variation types is imperative in order to prevent complications during surgical and orthopedic interventions.
