Oral mucositis is the most commonly reported side effect observed in neoplastic patients treated with chemotherapy and radiotherapy of the head and neck region as well as in patients who have received a haematopoietic stem cell transplant. The aim of the study was to assess the oral mucosa status in children with acute lymphoblastic leukaemia (ALL) during antineoplastic therapy.

The aim of the work was to determine the influence of tyrphostin AG1296, an inhibitor of platelet-derived growth factor receptor (PDGFR) tyrosine kinase, on autocrine growth of rhabdomyosarcoma (RMS) cells.

Radiotherapy-induced lumbosacral plexopathy in cervical cancer treatment is a very rare, but extremely serious complication. The clinical course is associated with severe bilateral lower leg pain, reduced sensation, different degrees of weakness, paresis or paralysis, and sometimes also urinary or fecal incontinence. Patient quality of life becomes significantly deteriorated. Escalating neurological disorders may make self-sufficient functioning impossible. Neurological symptoms, most often irreversible, may develop at different times after irradiation, even after more than

The typical symptoms of advanced cancer of the stomach are well known in clinical practice. The presented case concerns a patient with symptoms of left-sided renal colic, caused by a malignant tumour involving the ureter, which was diagnosed with a CT scan. The multifocal process, involving the stomach, two parts of the colon, the left ovary and the side of the pelvis, was confirmed only during surgery.

Analysis of changes in self-perception in post-mastectomy patients and its comparison with self-perception of healthy women.

Thermoablation of metastatic lesions in the liver is very commonplace. At present there are 3 essential techniques of access to carry out the procedure: open surgery, percutaneous technique and laparoscopic method. Percutaneous thermoablation is criticised due to the possible lack of radicalism. On the other hand, thermoablation during open surgery is a big perioperative trauma for the patient. The laparoscopic technique seems to be a compromise between the aforementioned techniques. The aim of this study was to present the technique and preliminary results of thermoablation of the liver carried out by means of the laparoscopic technique.

Bone is a common site of metastasis in patients with breast cancer. Skeletal complications associated with bone metastasis are commonly treated with bisphosphonates. However, there are a number of side-effects associated with these, such as renal failure, hypocalcemia and osteonecrosis of the jaw. We aimed to determine the effects of ibandronic and zoledronic acid on serum creatinine (SCr), calcium (Ca), phosphorus (P), alkaline phosphatase (ALP) and estimated glomerular filtration rates (eGFR). The objective was to determine the safety of these bisphosphonates, especially zoledronic acid.

Erlotinib and gefitinib are reversible EGFR-TKI administered orally. Results of the phase III study JBR.21 proved the clinical efficacy of erlotinib-based regimens as second- or third-line treatment of advanced NSCLC.

The goal of this study was to evaluate the activities of erythrocyte superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and the levels of glutathione (GSH) and ischemia-modified albumin (IMA), as potential markers in different histopathologic types of pediatric neoplasms. No studies on this subject have been reported to date.

Gastric cancer is characterized by varying secretion of mucus. Mucin producing gastric carcinoma (MUC) is thought to be a histological subtype with a worse prognosis. The aim of this study was to compare the clinicopathological differences between MUC and other types of gastric carcinoma without secretion of mucus (NMUC).

Lysosomal exoglycosidases, such as α-mannosidases (MAN) and β-galactosidases (GAL), are found in different glycoside hydrolase sequence-based families. Considerable research has proved plays the role of MAN, which play a key role in the modification and diversification of hybrid N-glycans, processes with strong cellular links to cancer. Therefore the study aim was to investigate the activities of MAN and GAL in larynx cancer compared to controls.

Several epidemiological studies have attempted to demonstrate a relationship between increased serum level of insulin-like growth factor 1 (IGF-1) and an augmented risk of developing colorectal cancers (CRC). The human IGF-1 gene is composed of 6 exons and demonstrated expression of 6 different splice variants (isoforms) of mRNA (IA, IB, IC, IIA, IIB and IIC).The aim of the study was to evaluate the expression of different isoforms of IGF-1 mRNA in CRC and normal colon tissue.

The need to establish conditions for safe irradiation was noted in Poland back in 1986 in the Atomic Law, but for over 16 years no regulations regarding this aspect were passed. The radiological incident in Bialystok (Poland) in 2001 undeniably accelerated the implementation of new legal regulations. Nevertheless, in the absence of national guidelines until 2002, most health care institutions resorted to the quality management system (QMS) model proposed by the ISO norm 9001:2000. Eventually, practice proved the theory and the aforementioned model was also implemented into Polish acts of law defining basic requirements for QMS in radiotherapy.

Acromegaly is a chronic disease caused by the excessive secretion of growth hormone (GH), and as a result, of insulin-like growth factor-1 (IGF-1). Untreated, the condition reduces the patients’ life expectancy and leads to a series of complications, among which an increased risk of carcinogenesis is considered most important.

The term proteomics was used for the first time in 1995 to describe large-scale protein analyses. At the same time proteomics was distinguished as a new domain of the life sciences. The major object of proteomic studies is the proteome, i.e. the set of all proteins accumulating in a given cell, tissue or organ. During the last years several new methods and techniques have been developed to increase the fidelity and efficacy of proteomic analyses. The most widely used are two-dimensional electrophoresis (2DE) and mass spectrometry (MS).

W European Journal of Cancer zaprezentowano wyniki randomizowanego badania III fazy, w którym oceniano skuteczność nowego nieinwazyjnego przenośnego urządzenia, stosowanego do leczenia chorych na glejaka wielopostaciowego w porównaniu do chemioterapii.

Aim of the study : The purpose of this study is to investigate the complementary/alternative medicine (CAM) usage and the factors affecting this among cancer patients in the western region of Turkey. 220 adult cancer patients participated in the study and 93 patients (42.3%) were found to use at least one CAM method. Material and methods : Our study was done by face-to-face communication in a university hospital, in Turkey. Oncology patients’ primary diseases, sociodemographic characteristics, complementary alternative medicine usage, psychological conditions and quality of life were evaluated with proper psychological scales. Patients using and not using CAM were compared with respect to Beck Depression, State Trait Anxiety and Beck Hopelessness scores. No statistically significant difference was detected between/among the groups in BDI (12.0 ±8.4, 11.9 ±8.7, p = 0.96), BHS (5.5 ±4.9, 4.8 ±4.4, p = 0.27) or STAI (43.7 ±8.0, 44.3 ±8.2, p = 0.64) scores. Patients using and not using CAM were compared with respect to WHOQOL-BREF quality of life scores. There was no statistically significant difference between/among the groups in WHOQOL-BREF sub-group scores (physical, psychological, social relations, environment, standardized by culture (environment), general health). Results : Nearly half of the patients (42.3%) in this region were found to be using at least one of the CAM methods. The patients mostly preferred herbal methods, with the leading product being stinging nettle (Urtica dioica). The severity of disease (recurrence and dissemination) and patients’ knowledge of the diagnoses were the most important factors affecting the CAM usage. Conclusions : The usage of CAM by oncology patients and the effects of CAM on the present medication prescribed by oncology practitioners must be remembered when they are admitted to polyclinics. Also it must be known that patients with advanced stage and patients with recurrence are more likely to use complementary alternative medications than early stage patients. Therefore oncology patients must be informed about CAM besides their clinical situations. At least physicians should give answers about the CAM to their patients.

Aim of the study : To analyse practical aspects of implementing the Personal Data Security Management System (PDSMS) in an oncology centre based on applicable legal requirements and professional standards. Material and methods : The research method is based on the analysis of legal documents, quality standards, analysis of progress in the achievement of objectives of the PDSMS based on interviews with heads of units and on review of data protection documentation. Results : The implementation of the PDSMS has caused the processed data to be adequately protected, minimised the risk of such data being used in a manner incompatible with their purpose, while ensuring the hospital’s compliance with applicable legal regulations. Conclusions : The implementation of the PDSMS has required technical and organisational measures to be taken in the centre’s organisational units, in particular appointing data protection officers, engaging staff in the data protection process by awarding them with authorisations to process data and familiarising them with securities that have been put in place.

A whole range of complex interactions develops between growing malignant neoplastic cells and non-malignant stromal elements of a tumour. The tumour microenvironment includes a number of interrelated elements: fibroblasts, macrophages and dendritic cells, endo­thelial cells, pericytes, inflammatory cells and extracellular matrix components. All these elements are actively involved in tumour growth and progression and angiogenesis, and can either promote or inhibit these processes. Understanding of the relationship between the various components of the tumour microenvironment and tumour cells may allow the introduction of combination drug therapy having different target points which gives hope of reducing the doses of medicines, and thus reducing their toxicity while increasing their efficiency.

Nowadays, diagnostics enables detection of cancer-related mutations. It concerns germline mutations as well as de novo mutations. The number of genetics tests available for specific tumors increase incessantly. BRCA1 and BRCA2 are high-penetrant genes, but still their functions and mechanisms leading to cancer caused by their mutations remain unknown. Germline alterations in BRCA1 and BRCA2 sequences are related to hereditary breast cancer syndrome (HBC), hereditary breast and ovarian cancer syndrome (HBOC), hereditary ovarian cancer syndrome (HOC). Primary and secondary tumors prevention and choice of the best treatment are the benefits of the detection of BRCA2 mutations. Research on correlation between the tumor phenotype and the type of mutation is continuously performed. This research may have an impact on the development of more effective drugs.
