Treatment of lung metastases in prostate cancer – case reports
05/2021 MUDr. Eva Kindlová
Prostate cancer is one of the most common cancers in men. Approximately 20 % of diagnosed patients had already developed metastases, in others the tumor may generalize after the locoregional treatment. The most frequent are bone and lymph nodes metastases, less frequented sites of metastases are lungs, liver, and other organs. The ways of treatment depend on whether the tumor is metastatic hormone-naive prostate cancer (mHSPC) or metastatic castration-resistant prostate cancer (mCRPC). Both local and systemic therapies are possible for treating lung metastases. Modalities of local therapy are surgical therapy and radiotherapy; hormone therapy, chemotherapy and ARTA therapy can be administered as systemic therapy. It is necessary to choose the optimal sequence of modalities and even use several lines of therapy to reach the best response. That can result in significant improvement of patienťs life expectancy and his quality of life as well.

Coincidence of oropharyngeal carcinoma and systemic progressive sclerosis in a 47‑year‑old patient – case report
05/2021 MUDr. Kateřina Licková; MUDr. Aleš Čoček, Ph.D.
Systemic progressive sclerosis is an autoimmune disease of unclear etiology characterized by vasculopathy and fibrosis. The incidence of malignancies in patients with this serious disease is higher than in the general population. The cause of this predisposition is not yet clearly defined. In our case we present a patient with systemic progressive sclerosis who was diagnosed with oropharyngeal carcinoma. The aim of this work is to draw attention to the complications in differential diagnosis and therapy in concurrent systemic autoimmune and cancer.

Systemic treatment of hepatocellular carcinoma
05/2021 MUDr. Beatrix Bencsiková, Ph.D.
Hepatocellular carcinoma (HCC) is a heterogeneous disease with an increasing incidence. Despite advances in systemic treatment, patients' prognosis remains poor. The outcome of treatment is affected by the extent of the disease, comorbidities of the patient, performance status, functional status of the liver parenchyma. Tyrosine kinase inhibitors (sorafenib, lenvatinib, cabozantinib, regorafenib), a monoclonal antibody against the vascular endothelial growth factor receptor (ramucirumab), improve overall patient survival. After more than ten years, the programmed cell death ligand inhibitor 1 atezolizumab in combination with bevacizumab statistically significantly prolonged the survival of patients with unresectable HCC. The aim of the article is to present the possibilities of systemic treatment of HCC in the first and second line of treatment.

New treatment options of transitional cell carcinoma of the urinary bladder in the era of immunotherapy
05/2021 MUDr. Tomáš Blažek; doc. MUDr. Renata Soumarová, Ph.D., MBA
The treatment of transitional cell carcinoma of the urinary bladder has been changed and evolved over the last decade. New findings in the field of immuno-oncology research largely contribute to treatment improvements. Conventional treatment modalities, i.e. surgical treatment, radiotherapy and systemic chemotherapy are expanded in the light of emerging immunotherapy options. Historically, one of the first immunotherapeutic agents was the attenuated Bacillus Calmette-Guérin (BCG) vaccine. It was used for the treatment of superficial, non-invasive transitional cell carcinomas of the bladder. Since that, the study of immune mechanisms and interactions in the tumor microenvironment, supported with the efficacy of the BCG vaccine, contributed to the development of further improvements in immunotherapy. In the modern era of immunotherapy, new active molecules, i.e. checkpoint inhibitors, are used. The use of these active molecules, targeting surface receptors located on the tumor cells and immune system of the patient, offer new perspectives in the systemic treatment of metastatic or locally advanced transitional cell carcinoma of the urinary bladder. Specific aspects of immunotherapy, particularly the effectiveness, tolerance and toxicity profile, which have an important impact on the quality of life of patients, make immunotherapy a new, alternative modality in addition to conventional systemic chemotherapy. The purpose of this article is to provide an overview of the current possibilities of systemic therapy for bladder cancer using immunotherapy and checkpoint inhibitors.

Alpelisib – the first PI3K inhibitor in the treatment of hormone‑positive, HER2‑negative breast cancer
05/2021 MUDr. Stanislav Hloušek
Despite all the progress of recent years, hormone therapy is still the main treatment modality in most patients with breast cancer. However, even for this treatment, resistance and disease progression may develop over time then it is necessary to find therapy for the second and higher lines of treatment. A suitable candidate for this situation appears to be alpelisib - an α-specific phosphatidylinositol-3-kinase (PI3K) inhibitor which, in combination with fulvestrant, has been shown to be effective in patients with advanced hormone-dependent, human epidermal growth factor receptor 2-negative (HER2-negative) breast cancer where PI3K catalytic subunit alpha (PIK3CA) mutations have been identified, after disease progression to hormonal therapy, even if cyclin dependent kinase 4/6 (CDK4/6) inhibitors have been used. This efficacy was documented in the SOLAR-1 study in patients after hormonal treatment failure compared to placebo and in the BYLieve study, which enrolled patients after previous progression to CDK4/6 inhibitors.

Avelumab and its therapeutic use in uro‑oncology
05/2021 MUDr. Jindřich Kopecký, Ph.D.
Immunotherapy has become an integral part of cancer therapy over the last decade. Treatment of uro-oncological malignancies is no exception. Gradually, nivolumab, pembrolizumab, and ipilimumab have become cornerstones for renal and bladder cancer therapy. Avelumab is becoming another monoclonal antibody that is effective in these cancers. And although it could be said to be another of the molecules. This treatment brings not only the possibility of a wider choice of effective therapy but also, for example, in the case of urothelial carcinoma, a new way of use.

Status of radiotherapy and concomitant chemoradiotherapy in locally advanced non‑small cell lung cancer and small cell lung cancer
05/2021 MUDr. Tereza Kohlová; doc. MUDr. Renata Soumarová, Ph.D.; Ing. Anna Negri; Ing. Šárka Šípová
Radiotherapy is the basic treatment modality in lung cancer across all its stages. There is a therapeutic benefit in settings up to 77 per cent, but the worldwide use is lower, in the Czech Republic about 25 percent. The advanced radiotherapeutic techniques, such as IMRT (intensity modulated radiotherapy) and IGRT with monitoring of respiratory motion (image guided radiotherapy), enable to reduce a dose to the organs at risk (heart, contralateral lung), the risk of pneumonitis and they prolong the survival.

Biologically targeted treatment in non‑small cell lung cancer or „do we always have mutations and PD-L1 examined?“ – case report
05/2021 MUDr. Gabriela Krákorová, Ph.D.
Metastatic or locally advanced non-small cell lung cancer (NSCLC) generally has a very poor prognosis. Five-year survival in stage IV is in the order of percentage units (less than 5%). Lung tumors with control mutations present are „different" tumors, with different behavior and prognosis. Treatment should always be initiated with knowledge of the mutation status and expression of programmed cell death-ligand 1 (PD-L1). PD-L1 expression should be reflexively determined in all NSCLC at the time of diagnosis by a pathologist and EGFR, ALK, ROS mutations reflexively in non-squamous NSCLC. The article presents a case report of a patient, where the omission of this examination may lead to the wrong choice of treatment scheme, but at least to a delay in the start of treatment. The article further discusses the possibilities of biologically targeted treatment for individual types of control mutations in lung cancer - EFGR, ALK, ROS, BRAF, KRAS, etc.

Atezolizumab in the treatment of lung cancer
05/2021 MUDr. Leona Koubková
Immuno-oncotherapy is already an integral part of lung cancer treatment. Especially in the first line treatment of non-small cell lung cancer (NSCLC) either in monotherapy of tumors with high expression of programmed cell death protein ligand 1 (PD-L1) or in combination with other treatment modalities leads to prolongation of overall survival and survival without progress. Atezolizumab, a monoclonal antibody against PD-L1, has been approved by the European Medicines Agency based on a number of studies to treat firstand higher-line NSCLC and as a first-line checkpoint inhibitor for first-line extensive small cell lung cancer.

Osimertinib in adjuvant treatment EGFR+ non‑small cell lung cancer – ADAURA trial
05/2021 MUDr. Ondřej Bílek
Approximately one-quarter of patients with non-small cell lung cancer are diagnosed with early or locally advanced stage of the disease suitable for surgery. There is a high risk of disease recurrence after adjuvant chemotherapy. The ADAURA trial demonstrated a significant benefit of adjuvant treatment with osimertinib in patients with non-small cell lung cancer with evidence of aberration of EGFR del19 or L858R in exon 21.

Current status of durvalumab in the lung cancer treatment
05/2021 Doc. MUDr. David Vrána, Ph.D.
Lung cancer represents one of the most frequent type of cancer. They can be classified as non-small cell lung cancer and small cell lung cancer. The treatment strategy of these tumors unfortunately didn't change significantly over the last couple years until the immunotherapy and tyrosine kinase inhibitors were launched into daily clinical practice. Immunotherapy, more specifically checkpoint inhibitors has quickly established their role in the treatment of several tumor types and nowadays has confirmed their effectivity in the first line of the palliative treatment of the non-small cell and small cell lung cancer including the maintenance therapy of the non-small cell lung cancer after radical chemoradiotherapy. Durvalumab is the monoclonal antibody against programmed cell death-ligand 1 (PD-L1), which blocks the interaction of the ligand PD-L1 and programmed cell death 1 receptor (PD-1) / CD80 which leads the significant increase in the immune response against cancer. At the same time this influencing of the immunity has brought the new adverse events which are different from the adverse events of the chemotherapy or tyrosine kinase inhibitors.

Long‑term effect of panitumumab therapy in a patient with primarily generalized colorectal cancer – case report
04/2021 MUDr. Anna Nohejlová Medková
Colorectal cancer is one of the most common tumors in the Czech Republic. For metastatic patients with the wild type RAS gene, the therapy with monoclonal antibodies targeting epidermal growth factor receptor (EGFR) is available. Most patients develop skin toxicity with this therapy, which has a major impact on their quality of life; so prevention of side effects and testing of RAS genes leads to an improved management of patients with metastatic colorectal cancer. I describe a case of a patient who underwent the therapy with panitumumab and his multiple liver metastases have disappeared.

The role of brachytherapy in the treatment of locally advanced cervical cancer
04/2021 MUDr. Radovan Vojtíšek, Ph.D.
Brachytherapy is indicated for the treatment of all locally advanced cervical cancers. Conventional planning based on two orthogonal X rays does not take into account the response to external beam radiotherapy (EBRT) and is thus not consistent with the current individual tumor extent. The concept, which takes into account the change in tumor size and the topography of organs at risk at the end of initial EBRT, is image guided adaptive brachytherapy (IGABT). It also allows the dose from brachytherapy to be increased to the newly defined target volumes according to the risk of recurrence. Image guided adaptive brachytherapy has a positive effect on locoregional control and on the reduction of late postradiation toxicity. The gold standard in IGABT planning of cervical tumors is the use of magnetic resonance imaging. Current treatment recommendations are based on repeated evaluation of the tumor by clinical examination and imaging methods, optimally by magnetic resonance imaging, with subsequent adaptation of dose prescription and target volumes according to response and risk of recurrence.

Cervical cancer screening and the role of HPV
04/2021 Doc. MUDr. Tomáš Fait, Ph.D
Human papillomaviruses (HPV) are the most important causative factor in the development of cervical cancer, but also other malignant and benign lesions of the female and male genitalia and partly other areas of the transition of the squamous and cylindrical epithelium. Preventing the acquisition of this infection is, in turn, the primary prevention of all of these lesions. The basis of secondary prevention, which is currently created only for the most common of the lesions cervical cancer is the early detection of cellular changes or detection of HPV infection, or a combination of both.

Molecular classification of endometrial cancers

The basis for the diagnosis of endometrial carcinoma is histopathological morphology. Since 1983 we used Bokhman classic division of endometrial cancer on two relatively wide groups of tumors different in pathogenesis. This classification meets the didactic purpose, provides easy orientation for epidemiological data, but is not suitable for patient stratification. This division is carried out wide overlap of clinical, pathological and molecular tumor features. The Cancer Genome Atlas (TCGA) project classifies endometrial tumors into four groups based on molecular genetic features. Integration of the histopathological findings along with molecular classification appears to be the best approach for evaluating each individual tumor.

Niraparib
04/2021 MUDr. Aleš Langer; MUDr. Hana Študentová, Ph.D.
Niraparib is younger member of PARP inhibitors family. Some PARP inhibitors are used in treatment of ovarian carcinoma routinely. This carcinoma is the most lethal of all Gynecological carcinomas. Incidence of this cancer is slightly decreasing, but it is still one of the most common cancers leading to death in women worldwide. The ovarian carcinomas are often diagnosed in an advanced clinical stage 3 or 4. Ovarian cancer is usually sensitive to platinum and taxane based chemotherapy, but treatment resistance and relapses develop throughout the disease course. Niraparib works as a maintenance therapy in a recurrent ovarian carcinoma. Niraparib provides the best results in BRCA1/2 mutated patients.
