Clinical Oncology - 2019;6(04)

[The number of cancer patients receiving regular dialysis treatment is increasing. These patients could benefi t similarly from the regular anticancer therapies. Data of the use of antineoplastic therapies in this vulnerable patient population mainly come from case reports and small case series. The lack of knowledge and lack of practical experiences in this patient group may lead to suboptimal cancer treatment. Defi ning the indication for antineoplastic treatment and choosing the appropriate drug is a challenging task and the patients’ prognosis and quality of life aspects should be evaluated carefully. The timing of anticancer treatment and the dialysis is also an important issue in this decision-making process. Close cooperation between the oncologists and nephrologists is essential in the proper antineoplastic treatment of the dialysed patients.]

[Treatment of cholangiocellular carcinoma]

ANDRÁS Csilla, ÁRKOSY Péter

[Tumors of the biliary tract are a rare entity, at the time of diagnosis most of the patients are in advanced stage and operation can’t be effectuated. After operation the risk of recurrence is high. The standard adjuvant therapy is capecitabin based on the results of BILCAP study. In advanced stage or in the presence of metastates the standard fi rst line treatment is gemcitabine and cisplatin therapy, there are noninferiority results from a Japan study with gemcitabin and S1 combination therapy. There was no evidence of second line treatment possibilities after gemcitabine and cisplatin therapy until 2019, but based on the results of ABC-06 study mFOLFOX could be the choice in the future. In the case of MSI-H/dMMR tumors immuntherapy should be considered. Personalised medicine with matched molecular targeted therapy is a new option. There are 2 new molecular targets, FGFR and IDH, the preliminary result are very promising.]

[Sequential therapy of metastatic renal cell carcinoma]

TORDAY László

[The incidence of renal carcinoma is on the rise in developed countries, with the tumor being among the 10 most common malignancies. However, the survival of patients with irresecable renal carcinoma has improved signifi cantly in recent years, mainly due to signifi cant advances in oncology treatment. The use of agents acting on the VEGF and mTOR signaling pathways is widespread and has become a standard clinical practice in fi rst and later line therapy. Recent clinical trials have provided many new drugs with new targets (cMET and AXL, FGFR, PD-1/PD-L1, CTLA-4) and combinations thereof, and have completely redrawn the treatment landscape of metastatic renal carcinoma and signifi cantly improved clinical results. This report reviews data on targeted drug therapy of renal cell carcinoma and discusses the therapeutic position of various drugs and combinations to our knowledge.]

[Targeted and immune therapies for hepatocellular carcinoma: Predictions for 2019 and beyond]

MASATOSHI Kudo

[Systemic therapy for hepatocellular carcinoma (HCC) has markedly advanced since the survival benefi t of a molecular targeted agent, sorafenib, were demonstrated in the SHARP and Asia Pacifi c trials in 2007. Treatment options for patients with advanced HCC increased by sorafenib, and long-term survival for patients with advanced stage HCC has become possible to some extent. However, development of a more potent fi rst-line novel molecular targeted agent replacing sorafenib and a potent second-line agent after disease progression on or intolerant to sorafenib has been warranted because sorafenib lacks tumor shrinking/necrotizing effects and induces relatively severe adverse events such as hand foot skin reaction. Many agents in the 1st line and 2nd line setting were attempted to develop between 2007 and 2016, but all of these clinical trials failed. On the other hand, clinical trials of 4 agents (regorafenib, lenvatinib, cabozantinib, and ramucirumab) succeeded in succession in 2017 and 2018, and their use in clinical practice is possible (regorafenib and lenvatinib) or underway (cabozantinib and ramucirumab). Furthermore, all of 5 clinical trials of combination therapy with transcatheter chemoembolization (TACE) plus a molecular targeted agent failed to date, however, the combination of TACE and sorafenib (TACTICS trials) was reported to be successful and presented at ASCO in 2018. Phase 3 clinical trials of immune checkpoint inhibitors and a combination therapy of immune checkpoint inhibitors and molecular targeted agents are also ongoing, which suggests treatment paradigm of HCC in all stages from early, intermediate and advanced stage, is expected to be changed drastically in the very near future.]

[Cell death]

KOPPER László, TÍMÁR József

[Cell proliferation and cell death (mainly apoptosis) have programs forming a network to maintain the functional integrity of the organism. Apoptosis has an external and internal units with ligands, signalling pathways and targets. Besides, some other participants (e.g. p53) are involved in the regulation of cell death. Although, apoptosis is a multitargeted process, there is no useful therapy, if it is needed, to correct accumulation of unwanted cells.]

[Prevention and treatment of venous thromboembolism in cancer patients]

[Venous thromboembolism (VTE) is a common and severe complication of cancer. Deep vein thrombosis and pulmonary embolism are the second most common cause of death in cancer patients. Cancer, tumor-related factors as well as patient’s general condition and comorbidities are responsible for the increased risk of VTE. Chemotherapy is one of the most important risk factors for VTE, increasing incidence of VTE by 6.5-fold. In my paper, current guidelines for cancer VTE prevention and treatment are reviewed. Hospitalized patients with active tumor are at higher risk for VTE, and thrombosis prophylaxis is recommended in all cases. Extensive, routine prophylaxis for advanced cancer patients receiving chemotherapy is not recommended, but may be considered in high-risk ambulatory cancer patients (Khorana-score ≥ 3). Risk factors may change during the course of cancer disease, and the score should be continually reviewed and prophylactic treatment changed as necessary. LMWH is the recommended agent for both primary and secondary prophylaxis/treatment. Direct oral anticoagulants (DOACs) are knocking on our door, but results from further clinical trials are pending to determine their exact role.]

[The significance of depressive disorders in patients with chronic kidney diseases]

ZALAI Dóra Márta, SZEIFERT Lilla, NOVÁK Márta

[In this article a practice-oriented narrative review of the depressive disorders in chronic kidney disease is provided. Depressive disorders affect approximately one fourth of the chronic kidney disease population. These mental disorders interfere with physical, cognitive and social functioning and are associated with poor prognosis of patients with chronic kidney disease. Bio-psycho-social factors, including immuno-inflammatory processes, disturbance in glucose- insulin homeostasis, sleep disorders, chronic pain, sexual difficulties, changes in social roles, losses in multiple areas of life and low social support increase the risk for the development of depression. Routine, regular screening of depression in the chronic kidney disease population seems to be warranted. Only limited published evidence is available on the therapeutic possibilities of depression in chronic kidney disease. Preliminary evidence indicates that short, structured psychotherapy may be effective for acute treatment and prevention of psychological distress. Some antidepressants can be applied without the need for dose adjustments. On the other hand, some of the psychotropic medications require dose reduction or should be avoided.]

[Dietary treatment of dialysis patients]

ZAKAR Gábor

[Adequate nutritional indices and intake are the corner stone of long term success of renal replecement therapies (hemo- and peritoneal dialysis, transplantation) characterized by favourable survial rates and a good quality of life. There has been no major change in basic principles of nutritional prescription (protein, energy, fluid intake, restriction of sodium, potassium and phosphorous), increasing emphasis has been placed on the reduction of calcium load and ”native” vitamin-D therapy in these patients. Less avareness has been put however in the past ten years (according to recent metaanalyses) on the role and replacement of the full scale of vitamins, in spite of their occasionally altered metabolism and replacement-requirements in ESRD patients. Usually there is a need for their replacement, but some of them are represented in abundant, sometimes toxic amounts in commercially available multivitamin preparates. With in the scope of general aspects of nutrition in ESRD patients, the article gives a detalied overview of their multivitamin recommendations and alternatives of a specified substition.]

[Prominents in Hungarian nephrology Professor Gyula Petrányi (1912-2000). Part II]

SZALAY László

[A nation can only survive and keep its identity through its traditions. This is why the initiative to launch this series coming from professor János Radó is worthy of attention. Gyula Petrányi is an outstanding personality in 20th century internal medicine, to be more precise in nephrology and immunology, his activity being wide-ranging. The first part of the current summary of his work deals with a tribute to his personality, and his role in immunomodularity treatment in glomerulonephritis. The second part shall cover his role in spreading renal biopsy, screening and caring kidney patients, dialysis, in developing kidney patients’ care, furthermore in clinicopharmacology and renal transplantation.]

[Covid-19 and the kidney]

PATÓ Éva, DEÁK György

[Covid-19 pandemy has emerged from Wuhan, China in December 2019. The infection affects not only the lung but other organs such as the kidney, as well. The relation between Covid-19 infection and the kidney is bidirectional. On one hand, Covid-19 infection may cause kidney damage in 50-75% of the cases resulting in proteinuria, haematuria and acute kidney injury (AKI). The etiology of AKI is multifactorial. Main pathogenic mechanisms are direct proximal tubular cell damage, sepsis-related haemodinamic derangement, citokine storm and hypercoagulability. The virus enters proximal tubular cells and podocytes via the ACE2 receptor followed by multiplication in the lysomes and consequential cell lesion. Histopathology shows acute tubular necrosis and acute tubulointerstitial nephritis. AKI is a strong predictor of mortality in critically ill patients. On the other hand, the risk of Covid-19 infection and mortality is substantially increased in patients with chronic kidney disease – especially in those with a kidney transplant or on dialysis – due to their immunocompromised status. Among haemodialysis patients, infection may spread very easily due to the possibility of getting contacted in the ambulance car or at the dialysis unit. The mortality rate of patients on renal replacement therapy with Covid-19 infection is 20-35%. In order to avoid mass infection it is obligatory to employ preventive measures and implement restricions along with (cohors) isolation of infected patients. In Hungary, every dialysis or kidney transplant patient with Covid-19 infection should be admitted to dedicated Covid-19 wards.]

[Hungarian Vasculitis Registry – results of the first five years]

HARIS Ágnes, TISLÉR András, ONDRIK Zoltán, FILE Ibolya, MÁTYUS János, ZSARGÓ Eszter, DEÁK György, AMBRUS Csaba

[Launching the Hungarian Vasculitis Registry aimed to collect information about prevalence and outcome of our patients with ANCA-associated vasculitis, and treatment protocols of the disease. The on-line data collection has been developing dynamically since its initiation five years ago, presently 278 patients’ files are available. Patients’ mean age is 58.2±14.5 years, 62% are women; their disease is associated with c-ANCA positivity in 51% and p-ANCA in 49%. At diagnosis GFR was 24.6±21.6 ml/min/1,73 m2, that time 29%, during the total follow up 39% of the registered subjects needed dialysis. Renal replacement therapy could be discontinued in 23% of them. In cases with focal histological changes, also with upper respiratory tract and skin involvement dialysis was significantly less frequently necessary, which underlines the importance of early diagnosis. In induction therapy steroid was administered for 94% of the patients, 85% of them got cyclophosphamide, 59% was treated by plasmapheresis, 11% got rituximab. Maintenance treat ment contained steroid in 80%, per os cyclophosphamide in 23%, parenteral cyclophosphamide in 22%, furthermore 40% of the patients got azathioprin, 8 subjects got mycophenolate and 6 got methotrexate. Median follow up was 30 months (IQR 6-78), during which period 20% of the patients died, 5% got kidney transplantation, and 5% were lost to follow up. Median survival was 14.8 years, five years survival was 85%, and ten years survival was 70%. Long term survival in patients with c-ANCA vasculitis seemed better comparing to p-ANCA vasculitis, but when correcting by age this difference disappeared. Predictors of death were age and dialysis dependent renal failure. Relapses developed in 27% of patients, 28% of them presented in the first year, 21% suffered it after five years of care. Collected data by the Hungarian Vasculitis Registry shows our society’s successful professional activity. Our results are comparable to the published data in the literature, yet there are several areas in our care where further improvements are warranted in order to increase our patient’s survival and quality of life.]
