Clinical Oncology - 2017;4(04)

[High-dose chemotherapy followed by stem cell rescue or allogeneic stem cell transplantation in the treatment of solid tumor with non-hematologic origin applied for more than three decades. High-dose chemotherapy with stem cell rescue is the part of standard fi rst line therapy for several chemosensitive tumors with unfavorable outcome (neuroblastoma, Ewing-sarcoma, medulloblastoma), and also successfully applied in certain therapy-resistant or recurrent solid tumors (germ cell tumors, Wilmstumor). Allogeneic transplantation with reduced intensity conditioning is still not successful in terms of survival in pediatric solid tumors with non-hematological origin. In present paper results of autologus and allogeneic stem cell transplantation in different pediatric solid tumor are discussed.]

[Inhibition of proteasome in cancer therapy]

KOPPER László

[The ubiquitin-proteasome pathway is the most important element in the regulation of intracellular protein metabolism. Its main function is the degradation of the unnecessary proteins either as part of normal metabolic balance or in case of misfolding or part of the deregulation as in cancer cells using proteolytic enzymes. The importance of this pathway has been acknowledge by Nobel prize. In certain diseases as in several malignancies, where the ubiquitin-proteasome pathway is not able to remove the proteins due to dysfunction or accumulation in a high quantity. The unregulated accumulation of proteins could lead to cell death. This phenomenon was proven by the appearance of proteasome-inhibitors targeting mainly myeloma. It should be mentioned that clinical aspects myeloma has been discussed in an excellent review by Mikala and his colleagues in Klinikai Onkológia.]

[Current treatment therapy of prostate cancer]

KULLMANN Tamás, KOCSIS Károly, SZEPESVÁRY Zsolt

[Prostate cancer is a frequent and usually slowly progressing malignancy. Promising opportunities and risks to avoid may occur along its diagnosis and treatment. The chance of early detection is high. The localised disease can be cured by radical prostatectomy and radiotherapy with equal probability. The post-prostatectomy biochemical failure may be controlled by radiotherapy. Even oligometastatic tumours can be cured by harmonised local treatment modalities. The survival of metastatic disease can be prolonged by several years. Effi cacy of traditional androgen deprivation may be enhanced with completion by upfront docetaxel chemotherapy or androgen synthesis blocking agents. However, local and systemic treatments are not harmless. Overtreatment as well as undertreatment has to be avoided upon therapy planning.]

[Complex therapy of bladder cancer]

LANDHERR László

[Bladder cancer is the most common malignancy involving the urinary system. Urothelial (formerly called transitional cell) carcinoma is the predominant histologic type in the developed countries, where it accounts for approximately 90 percent of all bladder cancers. The optimal management of nonmuscle invasive urothelial cancer is highly important. For patients with muscle invasive cancer the gold standard treatment is the cystectomy. If the patient unable or unwilling to undergo radical cystectomy with urinary diversion, complete TURBT combined with radiation therapy plus chemotherapy may offer an alternative bladder-sparing approach. Patients with muscle invasive disease and regional lymph node metastasis limited to the pelvis (N1-N3), but without more distant lymph node or visceral metastasis may be treated with six cycles of cisplatin-based chemotherapy followed by cystectomy or a combined-modality approach. In metastatic cases the combination chemotherapy may prolong survival and often provides palliation of symptomatic disease. Checkpoint inhibition immunotherapy has substantial clinical activity in post-chemotherapy patients and is the preferred therapy for patients who have progressed after platinumbased therapy or is not suitable for them.]

[Burnout syndrome - prevention and treatment]

SZY Ágnes

[The defi nition of burnout syndrome was established due to the recognition of changes that practising physicians experienced in their affective state and behaviour as well as the observation of physical symptoms that put their health at risk. Burnout syndrome can be characterised by a triadic set of factors: emotional exhaustion, depersonalisation, and decline of professional achievement. The present article aims to describe burnout syndrome with regard to the fact that similarities and differences between burnout syndrome and affective disorders such as depression must be highlighted. The focus of this article is that health care professionals burnout is multicausal and it is insuffi cient to put only the individual in the spotlight although it is imperative that we attend to the individual fi rst. It is essential to highlight the fact that without changes in the institutional work culture and requirements the prevalence of burnout syndrome can hardly decrease. It is also the aim of this work to provide the practising health care professional with information that they can easily transform into immediate help.]

[Risk assessment for child sexual abuse in the American legal practice]

KÓRÁSZ Krisztián

[The paper gives introspection into the child sexual abuse risk assessment practice in the USA by reviewing the literature. According to the definition of the World Health Organization, sexual assault is considered to be any act involving a child in a sexual activity if he or she can not be considered as prepared for the child's age or development. The author also makes an attempt to present some issues and pos­sible solutions regarding the current practice. ]

[Management of febrile neutropenia in the oncological practice]

SINKÓ János

[Febrile neutropenia is one of the most feared complications of anti-tumor therapy. It can either herald potentially fatal infection or contribute to suboptimal dose-intensity of cancer treatment. Optimal management of affected patients is based upon a multi-disciplinary approach dependent on several factors. Knowledge on institutional epidemiology and predefi ned management strategies improve quality and outcome of anti-infective therapy. In an era of more and more resistant pathogens and erosion of the antimicrobial armamentarium clinicians taking care of cancer patients carry increased responsibility in their professional activity. Here questions of practical importance related to prevention and therapy of neutropenic infections are outlined.]

[Omental infarction diagnosed with ultrasonography]

VÁRKONYI Ildikó, VÖRÖS Péter, SZÉKELY Eszter

[INTRODUCTION - Omental infarction is a rare entity, mimicking symptoms of acute appendicitis. Although omental infarction has typical morphology, both on sonography and CT, it is rarely diagnosed preoperatively. CASE REPORT - A 4-years-old girl presenting with right lower quadrant abdominal pain underwent abdominal sonography, which revealed normal appendix and a superficial hyperechoic solid mass at the site of the pain. The patient underwent laparotomy which confirmed the presumed diagnosis of partial omental necrosis. The necrotic tissue was resected, the appendix was normal. After uneventful postoperative course the child became symptom -free and was discharged. CONCLUSION - The sonomorphology of omental infarction is typical. The suspicion of this entity should be considered as a differential diagnosis of appendicitis, especially if normal appendix can be visualized.]

[Abdominal and thoracal manifestations of posttransplantation lymphoproliferative disorder in children]

VÁRKONYI Ildikó, NYITRAI Anna, MAGYAROSY Edina, RÉNYI Imre, SZEBERÉNYI Júlia, KIS Éva

[INTRODUCTION - Posttransplantation lymphoproliferative disorder is a secondary disease of transplanted patients, usually with good response to reduction of immunsuppressive therapy. PATIENTS AND METHODS - The lymphoproliferative disorder was diagnosed in four children among 139, renal, liver and lung transplanted patients. Clinical data (original disease, transplanted organ, age and time elapsed since transplantation at the diagnosis of the disorder) and imaging findings (chest X-ray, thoracal and abdominal computed tomography scans) were analysed retrospectively. RESULTS - Thoracal and abdominal forms were the most frequent manifestations of posttransplantation lymphoproliferative disorder in our patients. Following features have been diagnosed on imaging studies: multiple liver nodules (two cases), multiple nodules in the renal parenchyma (two cases), splenomegaly (two cases), bowel wall thickening (two cases). Retroperitoneal and mesenteric lymph node enlargement was found in all patients. Thoracal manifestations were as follows: mediastinal lymphadenopathy (two cases), hilar mass (one case), multiple pulmonary nodules (one case). Renal rupture with perirenal hematoma in one case, hilar mass envolving the main bronchus in one case, hepatic abscesses necessitating drainage in one case, and bowel wall necrosis in one case were the complications of posttransplantation lymphoproliferative disorder. CONCLUSION - Presenting symptoms are aspecific, often mimicking infection. Posttransplantation lymphoproliferative disorder has to be excluded if aspecific symptoms in a transplanted patient are present, or the patient does not react properly on antibiotics. First step investigations include chest X-ray and abdominal sonography. Neck, chest and abdominal CT are mandatory for detecting all manifestations, for staging the disease and to determine the best localization of obligatory biopsy.]

[MYCOSES IN PATIENTS WITH HAEMATOLOGICAL MALIGNANCIES AND STEM CELL TRANSPLANTATION]

PRINZ Gyula, SINKÓ János, NIKOLOVA Radka

[Patients with haematological malignancies and stem cell transplantation are frequently prone to develop invasive mycoses. Candida and Aspergillus are the major fungal pathogens that cause infections. The recently introduced new antifungal agents, voriconazole and caspofungin and new diagnostic methods changed the treatment strategies of invasive mycoses. The authors give an overview of the diagnostics, prophylaxis and treatment of the clinically important fungal infections.]
