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.]

[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.]

[Oncogene-targeted therapy of non-small cell lung cancer]

TANJA Cufer

[Lung cancer is the leading cause of cancer related deaths thus presenting one of the main public health related issues globally. Non-small cell lung cancer (NSCLC) represents approximately 85% of all lung cancer cases. Historically, platinum-based chemotherapy was the mainstay of systemic therapy for NSCLC, leading to median survival rates of only 8 to 10 months. Major improvement in the treatment of NSCLC was made through the identifi cation of key genetic aberrations (oncogene drivers) that drive tumor initiation, maintenance and progression and development of highly effective oncogene- directed therapies. Oncogene-directed therapies against epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) in conjunction with well-validated methods for the detection of their targets already represent a standard care of advanced NSCLC patients. Encouragingly, in the recent years a number of additional genetic aberrations have emerged as novel molecular targets with potential therapeutic implications in lung cancer. In this review a comprehensive overview of standard oncogene-directed therapies of advanced NSCLC is provided, challenges in overcoming resistance to those therapies are discussed and novel oncogene-directed therapies under development are briefl y presented.]

[Surgical view on the perioperative oncological treatment of liver metastases originated from colorectal cancer]

KUPCSULIK Péter

[Recent development of surgery resulted in fundamental changes in assessment of resectability of liver tumors. Surgical interventions became more radical and more effective. Colorectal liver metastasis (CLM) represents the most frequent hepatic tumor, where therapeutic options require close collaboration between surgeons and oncologists, and up-to-date approach from both. As the fact is, that CLM is a metastasis of a primary colorectal carcinoma, it seems to be obvious to apply perioperative chemotherapy. Results justify serious precaution. Neoadjuvant chemotherapy did not improve overall survival. Several data testify, that even perioperative chemotherapy is not indicated in these cases. Adjuvant chemotherapy can be applied after extended liver resections and two stages hepatectomies. About 20% of patients with initially inoperable CLM may be rendered resecable after systemic chemotherapy. Prognosis of synchron CLM is bad, 5 year survival is less than 20%. Disappearing CLM needs special respect, high level of perfection in liver surgery is essential. After chemotherapy postoperative morbidity is rising, technical diffi culties may occur. Further studies are required to examine possible effect of new targeted molecular therapy-based regimens on resectability. Individualized multidisciplinary treatment planning is mandatory.]

[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.]

[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.]

[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.]
