    Title translation Polypózy zažívacího traktu a Lynchův syndrom z pohledu patologa.
    Abstract Gastrointestinal polyposes and Lynch syndrome are a group of heterogenous hereditary tumor syndromes associated with an increased risk of developing colorectal carcinoma and other malignancies. Typical early manifestations of gastrointestinal polyposes include multiple polyps in the gastrointestinal tract. Early recognition of these syndromes enables patients carrying a pathogenic mutation to undergo screening and to instigate precautions to minimize the risk of developing tumors. In some cases, gastrointestinal lesions could be an early indicator of tumor syndrome and histopathologic examination could lead to a recommendation for genetic testing of patients and their families.

    Abstract Introduction: Primary breast sarcoma is a very rare malignant type of breast tumours with an incidence of 0.1% of all primary breast malignancies.
    Methods: We present a retrospective analysis of the case series from two hospitals in the Czech Republic with a review of the diagnostic and treatment approach to primary breast sarcomas with an analysis of published prognostic factors.
    Results: Eleven patients were included in the study, 9 women and 2 men. Statistical evaluation revealed that tumour size (
    Conclusion: The analysis did not prove any of the factors, such as age, tumour size, grade, or mitotic activity, to be statistically significant prognostic factors. Based on the literature review, the most common published prognostic factors are tumour size, margin status, and grade, but the results are ambiguous.

    Title translation Prediction of EGFR blockade responses in metastatic colorectal carcinoma.
    Abstract The combination of modern systemic chemotherapy and anti-EGFR monoclonal antibodies improves overall survival and the quality of life for patients with metastatic colorectal cancer. By contrast, the addition of anti-EGFR therapy to the treatment regime of resistant patients may lead to worse progression-free and overall survival. Therofore, identifying sensitive and resistant patients is key during initial decision-making. A number of clinical trials show that primary resistance to EGFR blockade is in most cases caused by constitutive activation of signalling pathways downstream of EGFR. Of the many biomarkers studied, only the KRAS and NRAS mutation status has reached clinical relevance in routine practice. The other markers (BRAF and PIK3CA mutations, PTEN and TP53 inactivation, EGFR and HER-2 amplification, epiregulin and amphiregulin overexpression, microRNA miR-31-3p and miR-31-5p etc.) still need to be validated. The accuracy of predictive diagnostic tools could also be increased by a combination of predictive markers on the next generation sequencing platform.

    Title translation The role of pathology in the predictive oncology of solid tumours.
    Abstract Recently, a new generation of pharmacons that are aimed to hit specific molecular targets has entered the oncology. Currently, testing of tumour tissue for the presence of particular molecules is needed. Those molecular entities predict probability of response to the targeted therapy. On a model of steroid hormone receptors and HER2 status testing a process of the predictive diagnostics is demonstrated. A contemporary concept of predictive oncology in the Czech Republic consisting of six "Predictive Oncology Laboratories" is described. Surgical pathology is shown as a key partner in the predictive oncology system.

    Abstract Immune checkpoint inhibitors (ICI) are the main therapy currently used in advanced malignant melanoma (MM) and non-small cell lung cancer (NSCLC). Despite the wide variety of uses, the possibility of predicting ICI efficacy in these tumor types is scarce. The aim of our study was to find new predictive biomarkers for ICI treatment. We analyzed, by immunohistochemistry, various cell subsets, including CD3+, CD8+, CD68+, CD20+, and FoxP3+ cells, and molecules such as LAG-3, IDO1, and TGFβ. Comprehensive genomic profiles were analyzed. We evaluated 46 patients with advanced MM (31) and NSCLC (15) treated with ICI monotherapy. When analyzing the malignant melanoma group, shorter median progression-free survival (PFS) was found in tumors positive for nuclear FoxP3 in tumor-infiltrating lymphocytes (TILs) (

    Title translation Breast cancer in BRCA1/2 mutation carriers.
    Abstract Inherited mutations in BRCA1 and BRCA2 genes represent the most important cause of hereditary breast cancer. This highly penetrating familial cancer syndrome, including also the onset of ovarian cancer and other malignancies at relatively low age, represents a substantial medical problem. The affected families should be managed actively. When compared to spontaneous tumors, the breast carcinomas in BRCA1 mutation carriers exhibit a relatively different, despite non-specific, phenotype (often triple negative, medullary features) arousing suspicion of hereditary background. In the contrary, the distribution of phenotypes of breast carcinomas in BRCA2 carriers is similar to distribution in the non-affected population. The lymphocytic lobulitis is observed significantly more often in non-cancerous breast tissue of BRCA1/2 mutation carriers, but again, this feature is not specific.

    Abstract Background/aim: The monoclonal antibody bevacizumab is a standard drug used in combination with oxaliplatin (FOLFOX) or irinotecan (FOLFIRI) based chemotherapy in the first or second-line treatment of metastatic colorectal cancer (mCRC). Our previous study identified and subsequently validated 4 microRNAs in a small group of patients as predictors of the therapeutic response to bevacizumab combined with chemotherapy. The aim of this follow-up study is to confirm the predictive ability of these tissue miRNAs in a larger independent cohort of mCRC patients.
    Patients and methods: The retrospective study included 92 patients with generalized-radically inoperable tumors treated with the combined therapy of bevacizumab/FOLFOX in a standard regimen.
    Results: Expression levels of candidate miRNA biomarkers (miR-92b-3p, miR-3156-5p, miR-10a-5p and miR-125a-5p) were determined in tumor tissue specimens and statistically evaluated. MiR-92b-3p and miR-125a-5p were confirmed to be associated with radiological response according to RECIST criteria (p=0.005 and 0.05, respectively) and to be up-regulated in responders to bevacizumab/FOLFOX therapy. Higher levels of miR-92b-3p were also significantly associated with extended progression-free survival (p=0.024).
    Conclusion: We have successfully confirmed miR-92b-3p to be up-regulated in tumor tissue of mCRC patients with good response to bevacizumab/FOLFOX therapy.

    Abstract Rationale: The use of cisplatin in patients with chronic kidney disease (CKD) is risky and depends on a number of factors. The optimal procedure in stage I of a non seminomatous germ cell tumor without proven lymphangioinvasion after orchiectomy is controversial and is the subject of a number of discussions due to the lack of randomized studies assessing individual treatment options. The adjuvant method of choice is surveillance or application of cisplatin-based chemotherapy with the risk of treatment related nephrotoxicity. Information about cisplatin safety in renal transplant patients is particularly limited. The aim of this paper is to share the experience with the application of adjuvant chemotherapy Bleomycin, Etoposide, Cisplatin (BEP) in high-risk patient with nonseminoma after kidney transplantation.
    Patient concerns: We report a case report of rare group of high-risk patient with non-seminomatous germ cell testicular tumor (NSGCT) after kidney transplantation before application of adjuvant chemotherapy BEP. Patient presented with month-long discomfort in the scrotal area. Previously, he was treated with chronic kidney disease based on chronic glomerulonephritis, which was treated with repeated kidney transplantation.
    Diagnosis: The ultrasound examination for a month-long discomfort in the scrotal area found a solid mass of the left testis. Radical inguinal orchiectomy confirmed NSGCT with the presence of lymphovascular invasion (LVI). Postoperative staging with computed tomography of the chest and abdomen did not show obvious dissemination of the disease.
    Interventions: Reducing original dose of chemotherapeutics according to the recommendations of the summary of product characteristics led to only a transient increase in creatinine levels.
    Outcomes: The 5-year risk of relapse in surveillance was reduced to around 3% by applying cisplatin-based chemotherapy.
    Lessons: Application of cisplatin-based chemotherapy is safe and effective in patients with CKD and in patients with a kidney transplant.

    Title translation Epiteloidní hemangioendoteliom v PET/ CT obraze.
    Abstract Background: At present, lung cancer ranks among the most frequent malignant diseases. However, according to literature data, mesenchymal lung tumors are very rare, representing less than 0.5% of all malignant lung tumours. Epithelioid hemangioendothelioma of the lungs belongs to this group of uncommon entities.
    Case report: We present a case of a 45-year-old male with a history of increasing dyspnoea and abdominal and back pains, developing over the past several months. Vertebral lesions were found on imaging studies. PET/ CT following 18F-fluorodeoxyglucose administration (FDG) showed a large FDG-positive malignant infiltration affecting the thorax, abdominal cavity, and bones. The extension and other characteristics of the mass on PET/ CT did not correspond to any of the common oncologic diseases. With its spread in a plaque-like form predominantly in the right hemithorax and on the surface of the liver, the disease closely resembled malignant mesothelioma. The primary tumour origin could not be clearly identified on PET/ CT scans but they allowed us to choose a suitable site to obtain tissue for pathologic examination. Based on a CT-guided bone bio-psy of the 7th right rib, the dia-gnosis was concluded as epithelioid hemangioendothelioma. Despite an early initiation of systemic treatment, the patient succumbed to the disease only 15 days after the dia-gnosis, due to superior vena cava syndrome and progressive pleural effusion leading to respiratory insufficiency.
    Conclusions: Given the extremely low prevalence of epithelioid hemangioendothelioma and its heterogeneous manifestation, it is impossible to base the dia-gnosis solely on disease symptoms, laboratory findings, and imaging modalities. In this respect, pathologic examination has a crucial role. For the same reason, there is a lack of recommendations for the standard-of-care systemic therapy of metastatic disease.
