Amifostine is well known cytoprotector which is efficient when administered before a wide range of antineoplastic agents. The aim of our study was to investigate amifostine effects on doxorubicin-induced toxic changes in rats. Amifostine (75 mg/kg ip) was given 30 min before each dose of doxorubicin (cumulatively 20 mg/kg ip, for 28 days).

The presence of metastases in lymph nodes is in correlation with Breslow tumor thickness. According to various researches, in melanoma with more than 4 mm Breslow thickness, lymph node micrometastases can be found in 60-70% of cases.

Methods: Peripheral blood and bone marrow samples of 28 patients with PV were analyzed. The diagnosis of PV was established according to the bone marrow criteria of the World Health Organization (WHO).
Background/aim: Introducing tyrosine kinase inhibitors (TKIs) has essentially changed curative approach, to be precise, clearly improved treatment efficacy for chronic myeloid leukemia (CML). Thus, the place and usage of allogeneic stem cell transplant (SCT) in CML treatment--as a former "nearly monopolistic" therapeutic manner--is nowadays controversial. The objective of this retrospective study was to evaluate the results obtained in the treatment of CML patients, with a particular attempt to define parameters critical for clinical benefit and superior overall outcome following allogeneic SCT.
View Article and Find Full Text PDFBackground/aim: Peripheral blood (PB) is used more frequently as a source of stem cells (SCs) for allogeneic transplantation. However, the influence of cell source on the clinical outcome of SC transplantation is not yet well established. The aim of this study was to compare the results of PBSC transplantation (PBSCT) with bone marrow transplantation (BMT) on the basis of engraftment, frequency and severity of immediate (mucositis, acute Graft versus Host Disease--aGvHD) and delayed (chronic GvHD--cGvHD) complications, as well as transplant-related mortality (TRM), transfusion needs, relapses and overall survival (OS).

The aim of this study was to evaluate the results of treatment of MM patients in our center with ASCTconditioning with melphalane or combining busulphane, cyclophosphamide and melphalane.
Methods: We performed 62 ASCT procedures in 47 patients from 1998 till 2008.
Background/aim: High-dose chemotherapy with autologous stem cell transplantation (ASCT) has shown to produce long-term disease-free survival in patients with chemotherapy-sensitive Hodgkin disease. The aim of the study was to evaluate efficacy of ASCT in the treatment of Hodgkin's disease.
Methods: Between May 1997 and September 2008, 34 patients with Hodgkin's disease in median age of 25 (range 16-60) years, underwent ASCT.
Background/aim: In patients with breast carcinoma there are many risk factors for assessment of breast carcinoma maturity and prognosis. Besides histological type of differentiation, cytologic criteria for the evaluation grade of the differentiation of infiltrative ductal breast carcinomas are very important for prognosis. The aim of this study was to define cytologic criteria for grading of infiltrative ductal carcinomas of the breast.

The aim of this study was to study the correlation between proinflammatory and immunoregulatory cytokines in periapical lesions and their relationship with cellular composition and clinical presentation.
Methods: Inflammatory cells were isolated from 67 human periapical lesions and cultivated for 24 h.
Background/aim: K-ras oncogene is mutated in about 20% of lung cancer. The purpose of this study was to investigate the predictive significance for therapeutic response of K-ras mutations in advanced non-small cell lung cancer (NSCLC) patients.
Methods: Bronchial aspirate samples were assessed prior to platinum-based chemotherapy start in 39 patients with stage IIIb or IV NSCLC.
Background/aim: Overexpression of p16INK4a has been found to be linked with genomic integration of high-risk human papillomavirus (HPV) and the developement of precancerous cervical intraepithelial lesions. The aim of this study was to examine is there a higher positive level of correlation between grade of histological dysplasia and p16INK4a level of expression in cervical smear, compared to results of Papanicolaou test. We also examined the correlation between HPV type, p16INK4a expression and Papanicolau test results.

Cryptic or "masked" BCR/ABL gene rearrangements may be found in cases with a normal karyotype and in cases with the complex karyotype, in which typical t(9;22) is not visible at the microscopic level. Those rearrangements can now be detected by fluorescence in situ hybridization.

In the course of diagnostic procedures, fine needle aspiration biopsy of the intrathoracic mass was performed. Cytologic analysis of the smear was performed because of clinical suspicion of plasma cell proliferative disease that was confirmed by bone marrow aspiration.

Methods: The study group included 23 patients with renal allograft dysfunction, selected from 56 patients who underwent renal transplantation. Etiologic diagnosis was made according to the clinical picture, histological findings during allograft biopsy, and cytologic examination of urine.
Background: Fluorescence bronchoscopy is one of the methods of the early detection of lung cancer that involves the large airways. The method is based on the detection of the altered autofluorescence of malignantly transformed tissue, and confirmed by biopsy and histopathologic examination.
Method: Fluorescence bronchoscopy was performed in 18 patients, mean age of 51.
Epithelioid vascular tumors are neoplasms formed by endothelial cells, morphologically similar to epithelial cells. Morphological shape of the cells in this tumors varies from benign to malignant forms, causing the diverse biological potential of the tumors. This case-report presents immunophenotypically interesting epithelioid vascular tumor of the upper vena cava manifested in thrombotic complications.

In this paper our experience in cytologic urinalysis as a diagnostic method of the acute renal allograft rejection was reviewed.
Methods: The study group included 20 of 56 patients with transplanted kidneys who were assumed for the acute allograft rejection according to allograft dysfunction and/or urine cytology findings.
Extemporary (EXT) analysis is unavoidable in establishing the tumor diagnosis, operability and the extent of the operation. Alternative approach is cytologic analisis which, because of its simple methodology, provides results even faster. In this paper, the results of cytologic imprints (CI) and EXT finding were compared with definite histopathologic diagnosis (HDP) to determine the value of both methods.

Intrathecal synthesis (ITS) of C3c and C4 complement components and IgG were determined by the method of cerebrospinal indexes (I), to examine their role in differential diagnosis of this syndrome. Correlative study between the CSF/serum ratio (Q) for albumin (Alb) and QC3c and QC4 in patients with no proven ITS of this two complement proteins, and the comparative study of the increased value of C3cI and C4I (and IgGI) between the examined groups of the patients was done.
