Opis:
Introduction and objective. αB-crystallin belongs to the ubiquitous family of small heat-shock proteins. It was discovered as a physiological protein of the eye lens, maintaining its liquid-like property. Furthermore, αB-crystallin was proved to playa bipolar role in both physiological and pathophysiological conditions. This review discusses current knowledge about the biology and genetics of αB-crystallin, and summarizes recent advances in understanding its role in ophthalmic and neurological disorders, as well as breast cancer, renal cancer and other malignancies. State of knowledge. α-crystallins are established as important elements of the protein quality control network, and consequently their defects are related to multiple human diseases. New studies highlight αB-crystallin’s involvement in proliferative diabetic retinopathy angiogenesis and point out its therapeutic potential in age-related macular degeneration. αB-crystallin is thought to be associated with the disease-causing protein aggregates, leading to its connection with such neurological disturbances as anaplastic astrocytoma, Parkinson disease, aging deficits in the peripheral nervous system and multiple sclerosis. In breast cancer, it was proven to be a marker of aggressive behaviur and cerebral metastases. Strong expression of αB-crystallin promoted growth and migration of clear cell renal cell carcinoma cells and was correlated with lower overall survival rate. Considering other malignancies, its various roles were established in colorectal and gastric cancers, head and neck squamous cell carcinomas and osteosarcomas. Conclusions. Further studies concerning αB-crystallin seem to be enormously promising, as they might improve our understanding of common human pathologies as well as contemporary diagnostics and treatment.

Opis:
The purpose of this article is to discuss the use of therapeutic options for the first-line systemic treatment of patients with advanced renal cell carcinoma under the B.10 drug program effective in Poland as of May 2022 - with a focus on intermediate and high-risk patient populations according to the IMDC. The specific situation created by reimbursement conditions with the exclusion of regimens combined with a tyrosine kinase inhibitor and immune checkpoint inhibitors along with the marginalisation of the use of an mTOr inhibitor necessitates a choice between two-drug immunotherapy or an antian giogenic drug in monotherapy. In this context, choosing the right treatment in the context of specific clinical situations is a challenge.

Opis:
Introduction: Sarcomatoid renal-cell carcinoma is a very rare cancer characterised with aggressive course of disease and poor prognosis. At present there are no standards of care for this histologic subtype of renal cell carcinoma resistant to various forms of systemic treatment. Methods: The study describes a case of 58 year old woman after left nephrectomy for clear cell carcinoma with sarcomatoid component and after resection of right-kidney tumour for synchronous clear cell carcinoma who received first-line bevacizumab and temsirolimus under the clinical trial, and then second-line chemotherapy based on gemcitabine and doxorubicin and ifosfamide-based third-line chemotherapy. The patient underwent pulmonary metastasectomy twice, and once a metastasectomy for liver metastases. Conclusions: Surgery (including metastases treatment) followed by the systemic chemotherapy seems to be correct option of treatment in patients with renal cell carcinoma with sarcomatoid features. The development of optimum method of systemic treatment requires further prospective randomised trials.

Objective: Results of second-line everolimus treatment in clear cell renal carcinoma. Material and methods: Clinical data of 32 patients of the Clinic of Systemic and Metastatic Malignancies, Centre of Oncology, Maria Sklodowska-Curie Memorial Institute (Krakow Branch) treated with second-line everolimus between 2011 and 2016 were analysed. Results: Median progression-free survival was 7 months. Stable disease was observed in 24 cases. Adverse events occurred in 59% of all patients, and the majority were mild and moderate (G1 and G2) according to CTCAE. The most frequent adverse events included anaemia, stomatitis, rash and fatigue. Conclusion: Molecularly targeted drugs offer the only effective and available therapy in Poland, which can be administered in patients with advanced renal cell carcinoma. Second-line everolimus is a valuable therapeutic option in the above mentioned group (following progression on first-line TKI therapy), especially when it is necessary to avoid the accumulation of similar adverse events after TKI treatment (different toxicity profiles).

Opis:
Renal carcinoma metastases to the gastrointestinal tract are seldom reported in medical literature. The study presented a case of a 76-year old female patient who underwent nephrectomy, due to T2N0M0 clear cell renal carcinoma and was additionally diagnosed with two metachronous metastases to the gall-bladder and pancreas. Abdominal ultrasound performed 32 months after nephrectomy demonstrated the presence of cholelithiasis and gall-bladder polyp. Laparoscopic cholecystectomy was performed. Clear cell renal carcinoma metastasis restricted to the gall-bladder mucosa was diagnosed on the basis of the histopathological examination. After surgery the patient remained under follow-up. In December, 2009 (47 months after nephrectomy) abdominal computer tomography (CT) revealed the presence of a tumor located in the tail of the pancreas. Distal pancreatic resection and splenectomy was performed. The histopathological examination confirmed the presence of clear cell renal carcinoma metastasis. The patient is in good general condition, under follow-up at the Oncological Outpatient Clinic.

Opis:
Cancer cells are characterized by an aberrant increase in protein N-glycosylation and by disruption of E-cadherin-mediated adherens junctions. However, the relationship between alterations in N-glycosylation process and loss of E-cadherin adhesion in cancer remains unclear. The mechanisms of altered expression of adhesive glycoproteins in cancer cells have not been fully elucidated. Thus, the aim of this study was to examine the expression of E-cadherin and sialyl Lewisa/x, NeuAcα2-3Gal, NeuAcα2-6Gal/GalNAc structures in the normal renal tissue and intermediate and cancerous tissues from patients with clear cell RCC. Moreover, we attempted to correlate the E-cadherin expression with some specific sugar residues of renal cancer tissue glycoproteins. The expression of E-cadherin was analysed using ELISA test and immunoblotting. Oligosaccharide structures and sialylation level were detected with ELISA test using specific biotinylated lectins or antibodies. A significant decrease of E-cadherin expression as well as a significant increase in sialylated oligosaccharides level in intermediate zone and renal cancer tissue in comparison to normal renal tissue are reported. Significant decrease in expression of cadherins and increase in sialylation of oligosaccharide structures in renal cancer tissue in comparison to normal renal tissue, and in renal cancer tissue in comparison to intermediate zone of renal tissue, are important for the future research concerning detection and quantification of cadherins and sialylated oligosaccharide structures in urine and cells of urinary sediment as possible non-invasive marker of early RCC.

Venous thromboembolism is one of the main causes of sudden death in hospitalized patients. Among the classical risk factors involved, cancer occupies a special place. Up to 20% of oncological patients will develop a VTE episode, and in 10% of them, it will be a direct cause of death. In the case presented below, incidental pulmonary embolism and renal tumor were diagnosed at the same time, and there was an event of embolism despite optimal antithrombotic treatment. Such a scenario of complications may correlate with a clinically advanced stage of cancer, and may be associated with a poorer prognosis, requiring an individualized therapeutic management.

Opis:
Renal cell carcinoma accounts for about 2-3% of all malignancies. It is characterized by a high frequency of metastases, which are most often observed in the lungs, bones, liver, brain and regional lymph nodes. Literature highlights the rare occurrence of renal cancer metastases to the head and neck, even though it is the third most common cancer that metastasizes to the head and neck. Below we present a case report of metastases of clear cell carcinoma from a kidney to the organs of the head and neck. The analysis was carried out retrospectively based on medical records of a patient hospitalized at the Department of Otorhinolaryngology, Head and Neck Surgery of the Medical University of Warsaw in the years 2009-2019. We describe an 81-year-old man after left-sided nephrectomy due to clear cell carcinoma, with numerous distant metastases, who was diagnosed with metastases to the left submandibular salivary gland 8 years after primary surgery, followed by a diagnosis of metastasis to the right submandibular salivary gland 3 years later. The patient underwent 2 radical procedures to remove the submandibular salivary glands. Due to the presence of lung metastases, treatment with a tyrosine kinase inhibitor was also implemented.

Opis:
Renal cell carcinoma (RCC) and bladder cancer (BC) are among the most frequently diagnosed urinary system cancers worldwide. They are characterized by high mortality and recurrence rates. In response to the rising incidence and mortality rates, scientists are exploring innovative diagnostic and therapeutic methods. Metabolomics, which analyzes metabolite levels, may enable early diagnosis and monitoring of therapy progress. Compared to other omics technologies, it focuses on the outcomes of metabolite activity, providing a unique perspective on processes occurring in cancer cells. Metabolomic analyses utilize techniques such as mass spectrometry. These methods allow the identification of biomarkers and precise determination of the chemical composition of biological samples. However, the most commonly used method is liquid chromatography-mass spectrometry (LC-MS), which enables the most comprehensive screening of cancer metabolomes. Recent studies show significant progress in recognizing characteristic metabolites associated with urological cancers, although this area remains partially unexplored. Research on circulating metabolites, especially those present in easily accessible samples like blood or urine, demonstrates promising potential in clinical practice. Study results reveal differences in metabolic profiles between various stages of cancer development, which may have clinical significance. The future of this field involves an increasing number of clinical cohorts, standardization of sample preparation, and further improvements in instrument sensitivity and speed. LC-MS-based metabolomics has the potential to contribute to the improvement of diagnostics, therapy, and the quality of life of patients with some urological cancers. However, challenges, such as the lack of uniform methodologies and understanding of metabolite determinants, require further research and innovation.

Opis:
Extracellular matrix metalloproteinases - MMPs, also referred to as matrixines, provide a group of proteolytic enzymes. They belong to the family of endopeptidases that break down elements of extracellular matrix, resulting in its continuous remodelling. Their activity is regulated at multiple levels, while tissue inhibitors of metalloproteinases play a major role in this process. Metalloproteinases play a significant part in neoplastic processes due to their contribution to local tumour invasion and formation of distant metastases, as well as to angiogenesis Urinary tract tumours pose a significant diagnostic and therapeutic challenge and their incidence tends to grow every year. The aim of this part of review is to describe extracellular matrix and matrix metalloproteinases and to highlight the contribution of matrix metalloproteinases in the development of renal clear cell carcinoma.

Opis:
We presented a 39-year-old male who developed progressive cancer disease 4 years after nephrectomy due to clear cell carcinoma. He was diagnosed with locally reccurence and metastases to the liver, spleen and abdominal muscles. The patient was treated with sunitinib and then after disease progression – with sorafenib. We observed 18 months of cancer control (TKI-TKI). After second progression everolimus was administered. Third line everolimus therapy helped to achieve durable stable disease with PFS 46 months till now (May 2015). The patient remains in very good performance status with minimal toxicity from the regimen. This case illustrates a long term survival for patients with metastatic renal cell carcinoma, a malignancy with historically poor prognosis. The use of three sequential targeted therapies (TKI – TKI – mTORi) helped to achieve over 5 years or disease control, with rarely seen long-term response to third line treatment (mTORi) – where stabilization is good enough. We discussed therapeutic strategies in metastatic renal cell carcinoma according to the literature and therapeutic possibilities in Poland.
