[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.]

[MCP-1 (monocyte chemoattractant protein-1) G/A and T-bet (T-helper promoter factor) C/G polymorphisms in primary Sjögren’s syndrome and systemic lupus erythematosus]

KOVÁCS Attila, KONCZ Ágnes, ENDREFFY Emőke, ARANKA László, PETRI Ildikó, ELLER József, SZALAI Csaba

[INTRODUCTION - Monocyte chemoattractant protein- 1 (MCP-1) is a β-chemokine involved in the attraction and accumulation of mononuclear granulocytes towards the site of inflammation. One of the transcriptional factors of T-cells is called T-bet. PATIENTS AND METHODS - The authors investigated the MCP-1-2518 G/A and T-bet 310 C/G (His33Gln) polymorphisms evaluating the distribution of the specific genotypes in 45 patients with primary Sjögren's syndrome (pSS), 51 patients with systemic lupus erythematosus (SLE), and in 320 healthy blood donors as the control group. MCP-1-2518 G/A and T-bet 310 C/G polymorphisms were detected with molecular genetic methods from the purified genomic DNA. RESULTS - The frequency of the MCP-1-2518 AG heterozygous genotype decreased tendentiously only in SLE patients, while the frequency of the MCP-1 AA homozygous genotype increased comparing to the control group (13.7% vs. 5.9%; Pearson’s χ2 test=6.125, ns.). Analyzing the genotype frequency for the MCP-1 wild (GG) and AA homozygous genotypes in pSS group, the MCP-1 AA homozygous genotype proved to be more frequent comparing to the control group (82.8%:17.2% vs. 90.7%:9.3%; Pearson’s χ2 test 1.755, ns). These relations showed only tendentious association in the SLE group (81.6%:18.7% vs. 90.7%:9.3%; Pearson’s χ2 2.811, p=0.094, ns.) There was not any significant correlation between the investigated MCP-1- 2518 G/A and the T-bet 310 C/G polymorphisms and the TNF-α -308 G/A and -238 allele polymorphisms. The frequency of T-bet was equal in relation with heterozygous (CG) to wild CC genotype in the investigated two autoimmune disorders. The GG homozygous genotype for T-bet could not be found in SLE and pSS groups, likely to be a protective factor. CONCLUSIONS - The above mentioned polymorphisms didn’t show any significant correlation with TNF-α -308 and -238 allele polymorphisms. The further research of the MCP-1 G/A and T-bet C/G polymorphisms is important, because of their possible prognostic importance for SLE and pSS.]

[Kinetic measurement on flow cytometer simultaneous monitoring of intracellular progresses]

MÉSZÁROS Gergő, RÓNAI Katalin Zsuzsanna, TOLDI Gergely, KAPOSI Ambrus, VÁSÁRHELYI Barna, TRESZL András

[INTRODUCTION - Flow cytometry provides an opportunity for real-time monitoring of intracellular processes in several cell populations simultaneously. Cells stained with specific fluorescent dyes are sequentially measured during kinetic FACS measurements. Fluorescent light signals obtained in cells are recorded and analyzed to describe the alteration of the investigated parameter(s) over time. The use of kinetic FACS assays is not spread as there was no mathematic algorithm to characterize objectively the distribution of data and kinetic changes. MATERIALS, METHODS, RESULTS - We developed a new approach which fits functions to measured data sets, describes the statistical distribution and forms a basis for statistical comparison between individual kinetic measurements. We created two FACS assays on BD FACS Aria instrument. The first one monitors calcium flux, generation of reactive oxygen species and mitochondrial membrane potential, while the second one monitors mitochondrial calcium flux, nitric oxide generation and plasma membrane potential in CD4+ and CD8+ lymphocytes simultaneously before and after the administration of a lymphocyte activator. CONCLUSIONS - This technique may be used to investigate purposes (i.e. to test the impact of any agent (such as immunmodulatory drugs) on cellular processes in lymphocytes) and to diagnostic purposes (i.e. to test the alteration of lymphocyte activation characteristics in disease).]

[Treatment of testicular germ cell tumors – an up-date]

BAKI Márta

[The frequency of germ cell tumors is about 1% of all male cancers. The incidence increases in developed countries. The prevalence is the highest among the young males. The histologic type, extent of disease and therapy is based on international guidelines. The surgery, radio- and chemotherapy can achieve cure in the germ cell cancer patients. Regarding the late toxicity, the minimal invasive tumors are suggested to keep on the wait and see policy. The complex therapy of poor risk groups reached more than 80% permanent remission rate. The chemotherapy is based on cisplatin, but in second and third line therapy paclitaxel, gemcitabin and oxaliplatin is widely used. After the cure of germ cell cancer patients the careful follow up is mandatory.]

[INTRODUCTION - Bortezomib, a first-in-itsclass proteasome-inhibitor drug was registered in 2004 for the salvage treatment of relapsed and/or refractory multiple myeloma. We have been using this drug in our department for the treatment of myeloma patients since 2005. PATIENTS AND METHODS - In this retrospective study, treatment results (response rate, response duration, survival) as well as the complications and side effects were analysed based on 60 myeloma patients treated over a period of 18 months. The patients received at least one full cycle of non-first-line bortezomib-based (predominantly combinational) therapy. RESULTS - At least minimal laboratory and/or clinical response was observed in 47 of the 56 patients who could be analysed. Clinically meaningful (at least partial remission) response was seen in 41 of 56 patients. Immune-fixation negative complete remission was achieved in six patients. Median progression-free survival of our patient population was 13 months (10.8-14.8 months, n=49, adjusted for patients lost in the first 6 weeks and for those with less than 6 weeks of follow-up). As for overall survival, the median has not been reached, while treated patients had an 80.3% probability of survival at one year. CONCLUSIONS - Based on the treatment results of 60 myeloma patients, bortezomibbased therapy is clearly effective in relapsed and/or refractory myeloma.]

[Cancer treatment induced gastrointestinal complications]

AL-FARHAT Yousuf, AUTH Péter

[Systemic therapy (ST) (including chemotherapy, targeted therapy, and immunotherapy) or radiation therapy (RT) can induce gastrointestinal side effects, which frequently affect patient’s quality of life. Sometimes side effects could be dose-limiting, or a reason to stop the treatment. The incidence and severity of gastrointestinal complications in patient’s receiving ST, RT, or chemoradiotherapy are affected by numerous factors, including: therapeutic agents, doses and route of administration, target of the RT (upper, lower abdomen or body) and individual patient variability (age, sex, prior cancer therapy, comorbidities, performance status). Mucositis occurs in approximately 20% to 40% of patients receiving conventional chemotherapy, 80% of patients receiving high-dose chemotherapy, nearly all patients receiving head and neck radiation therapy. mTOR inhibitor-associated stomatitis (mIAS) is the most frequent dose-limiting toxicity (52.5%). More than 90% of patients receiving highly emetogenic chemotherapy will have episodes of vomiting. However, only about 30% of these patients will vomit if they receive prophylactic antiemetic regimens.]
