Clinical Oncology - 2016;3(01)

[The last decades opened a new era of oncotherapy, including the development of targeted therapies for different subtypes of malignancies. Cutaneous adverse events are the most frequent toxicities among side effects of personally tailored molecular targeted agents. This review summarizes the practical aspects of the clinical characteristics and the optimal treatment of skin-related complications caused by oncological drugs.]

[Prevention and therapy of cervical cancer ]

RÉVÉSZ János, BÍRÓ Mátyás

[The global incidence of cervical cancer is ~530000, the death rate is ~270000 per year. These data shows, that cervical cancer is the fourth common malignancy in woman worldwide and the leading cancer related death in developing countries. HPV infection is the most important factor of carcinogenesis. Immunisation against HPV can prevent infection, and decrease the cancer incidence. In case of invasive cancer the therapeutic principles are surgery and radiotherapy. In case of high risk patients and/or locally advanced disease the adjuvant and neoadjuvant cytostatic treatment has limited evidences. The traditional cytotoxic therapy and the recent antiangiogenic therapy recommended for patients who have extrapelvic metastasis, residual tumor after primary radiotherapy or recidiv non curable tumor by radiotherapy or radical surgery.]

[Treatment of mesothelioma - an update]

MOLDVAY Judit, HEGEDŰS Balázs, KOVÁCS Ildikó, DÖME Balázs

[Malignant pleural mesothelioma is an aggressive tumor arising from the mesothelial cells lining the pleura. It is an asbestos related disease with increasing incidence both in Europe and in Hungary. This often fatal disease is characterized by rapid progression, and unfortunately, treatment options are very limited to date. Thus every effort should be made to better understand the pathological and molecular biological characteristics of this disease in order to develop new treatment strategies. This summary reviews the treatment options available today as well as the new therapeutic approaches at the experimental and clinical investigation stage.]

[Follicular lymphoma - a way to personalized and targeted therapy ]

BÖDÖR Csaba, SCHNEIDER Tamás

[Although follicular lymphoma is the most frequent non-Hodgkin’s lymphoma with an indolent clinical course, it is a rare disease. Patients with FL are characterized with a long survival with a relatively good quality of life, however using the current standard chemo-immunotherapy, the disease is considered incurable. The increasing knowledge of the molecular genetic background of the disease and the role of the reactive microenvironment lead to a better understanding of the pathogenesis of follicular lymphoma. Furthermore, the detailed functional characterization of the various cell surface antigens and deciphering the complex network of signaling pathways catalyzed the development of a number of novel targeted therapies (monoclonal antibodies, kinase- and NFκB-inhibitors), while understanding the effects of the cell surface receptors of cytotoxic T-cells initiated development of the monoclonal checkpoint inhibitors. The epigenetic therapies represent a novel therapeutic area with methyltransferase inhibitors demonstrating the most favorable results. Among the novel therapies, the immunomodulatory lenalidomide appears as the most promising and most effective drug, which acts via regulating the microenvironment, and in combination with rituximab in fi rst line setting it demonstrated similar effi cacy to the current standard protocols. Indeed, the rational use of the novel data and drugs paves the way towards personalized and targeted therapies for FL, resulting in more effective treatment and further improvement in patients’ survival, with a very long disease-free survival representing cure.]

[Decreased bone resorption in H1-receptorantagonist treated allergic children]

FERENCZ VIKTÓRIA, BOJSZKÓ ÁGNES, PALLINGER ÉVA, LAKATOS Péter, FALUS ANDRÁS, HORVÁTH CSABA

[INTRODUCTION - Histamine receptor antagonists seems to have effect on bone metabolism according to previous studies. We investigated the bone turnover in allergic children who were treated with H1-histaminreceptor (H1R) antagonists. PATIENTS AND METHODS - The biochemical bone turnover markers [β-CrossLaps (β-CTx), osteocalcin (OCN), β-CTx/OCN ratio], parathyroid hormone (PTH) and the 25(OH)vitamin D3 were determined in 37 H1Rantagonist treated multiplex allergic children and in 21 age and gender matched healthy children. The intracytoplasmatic histidine decarboxylase (HDC), histamin, and surface H1 and H2 receptors expression were assessed by flow cytometry on peripheral leukocytes. The distribution of lymphocyte subpopulation were also determined. RESULTS - The serum OCN, PTH and 25(OH)vitamin D3 levels did not differ between the healthy and the allergic groups. However, the β-CTx was lower in the H1Rantagonists treated allergic children (1090.82±80.25 pg/ml) in comparison with controls (1456.58±95.81 pg/ml; p=0.006). The β-CTx/OCN ratio was found to be lower in the H1R-antagonists treated allergic than in the controls (9.24±0.608 vs. 12.65±0.53; p=0.001). β-CTx serum level correlated with OCN in the controls (r=0.845, p<0.001) and in the H1R-antagonist treated allergic, too (r=0.519, p=0.005). Higher HDC expression and H1 receptor down regulation was found in allergic children. The CD3+/CD16-56+ T cells were in higher rate in children of control group. CONCLUSION - Decreased bone resorption was found among H1 receptor antagonist treated allergic children, which is indicated by serum markers. Therefore, bone turnover is shifted toward bone formation in the H1Rantagonist treated allergic subjects.]

[Pseudolymphoma orbitae]

VÁNCSA Andrea, GERGELY Lajos, NEMES Zoltán, BÍRÓ Edit, ILLÉS Árpád, BAKÓ Gyula

[INTRODUCTION - Pseudolymphoma orbitae is a rare and difficult entity. The cooperation of the pathologist and clinician is needed to properly manage the patient. CASE REPORT - The authors report the case history of a 38 years old male patient. His disease started at the age of 30. He was previously treated with allergic rhinitis. No definitive diagnosis was made for eight years. Several surgical biopsies were made from nasal mucosa, but no specific histologyical diagnosis was applicable. At the age of 30 he developed an unilateral exophthalmus on the left side. Thyroid associated ophthalmopathy was ruled out several times with laboratory analysis. High dose methylprednisone therapy was repeatedly given with limited results. At the age of 34 orbital CT and MRI scan confirmed the pseudotumour orbitae already compressing the optical nerve. Laboratory analysis again ruled out thyroid associated ophthalmopathy. Churg-Strauss syndrome, Wegener’s granulomatosis or Sjögren’s syndrome could be ruled out. A bone marrow trephine biopsy excluded systemic hematological disease as well. A biopsy was performed from the retrobulbar mass again, which confirmed the lymphoid hyperplasia with B-cell dominance. High dose methylprednisone and local irradiation resulted only moderate decrease of the mass, so systemic chemotherapy was started using CVP (cyclophosphamide, vincristin, prednisone) then CHOP (CVP + anthrycycline) polychemotherapy for eight cycles and subcutaneous interferon-α for 20 months. CONCLUSIONS - This resulted a complete regression of the disease, and the patient is well for 48 months now.]

[The red eye]

IMRE László

[Eye redness may be a sign of a variety of eye diseases with different severity. Most often redness is relatively harmless, such as conjunctivitis, but it can be a serious illness with visual impairment and even lasting consequences in the background of redness. It is therefore important for non-ophthalmologists to be informed and to know the basic types of redness of the eye and to recognize typical and characteristic forms of appearance. Based on these, they can decide whether the patient can be treated or forwarded to an ophthalmic institution. In the present continuing education article we try to summarize the causes of the red eye, primarily according to the characteristics of the redness of the eye and the anatomical localization. During the investigation of a patient with red eye, the type of the redness can be determined most by diffuse illumination and by naked eye inspection without any other means. It is important to know the principal features and causes of redness of conjunctival or ciliary or scleral origin, possible other recognizable differences (e.g. conjunctival papillae or follicles or conjunctival chemosis). We have attempted to illustrate these with a number of photographs, starting with a schematic representation of the characteristic features of redness. We tried to emphasize cases suitable for treating by non-ophthalmologists and tried to draw attention to the importance of referral un­clear or complicated cases.]

[MOLECULARLY TARGETED BIOLOGICAL THERAPY IN THE TREATMENT OF SOLID TUMOURS PART ONE - BREAST CANCER AND COLORECTAL CANCER]

LÁNG István, HITRE Erika

[Modern biological oncotherapy of solid tumours means targeting various kinase inhibitor pathways either by specific monoclonal antibodies against extracellular receptors or ligands (trastuzumab, cetuximab, panitumumab, bevacizumab) or by small molecular weight oral kinase inhibitors that interfere with intracellular signal transduction (imatinib, sunitinib, lapatinib, erlotinib, gefitinib, sorafenib). Here we review the clinical use of targeted biological agents in breast and colorectal cancer.]
