A potential reason for poor survival among patients with muscle-invasive bladder cancer (MIBC) in Poland is initial disqualification from curative treatment due to advanced stage of the disease or low performance status. The aim of this study was to describe patterns of care in patients with newly diagnosed MIBC. This is a multicentre retrospective cohort study involving 296 consecutive patients with primary histologically diagnosed MIBC. Therapeutic decisions and potentially underlying clinical factors were analysed...

AIM OF THE STUDY: The (57)Co radioisotope has recently been proposed as a hypothetical brachytherapy source due to its high specific activity, appropriate half-life (272 days) and medium energy photons (114.17 keV on average). In this study, Task Group No. 43 dosimetric parameters were calculated and reported for a hypothetical (57)Co source. MATERIAL AND METHODS: A hypothetical (57)Co source was simulated in MCNPX, consisting of an active cylinder with 3.5 mm length and 0...

AIM OF THE STUDY: Many studies have shown that interferon-α (IFN-α) enhances the antiproliferative effect of gefitinib in some solid tumours. We aimed to determine the effect of combining IFN-α with gefitinib in human non-small cell lung cancer (NSCLC) cell lines (A549, H1299, HCC827) with different EGFR and K-Ras gene statuses. MATERIAL AND METHODS: An MTT assay was used to assess cell proliferation. Apoptosis was detected by an Annexin V/propidium iodide assay using flow cytometry, and western blotting was used to determine the expression of epidermal growth factor receptor/phosphorylated epidermal growth factor receptor (EGFR/p-EGFR) and signal transducers and activators of transcription 3/phosphorylated signal transducers and activators of transcription 3 (STAT3/p-STAT3)...

AIM OF THE STUDY: To determine the significance of expression of synaptophysin, chromogranin A, and Ki-67 and their association with clinicopathological parameters, and to find out the possible prognostic factors in gastric neuroendocrine carcinoma (G-NEC). MATERIAL AND METHODS: We investigated the immunohistochemical features and prognosis of 62 G-NECs, and evaluated the association among expressions of synaptophysin, chromogranin A, and Ki-67, clinicopathological variables, and outcome...

AIM OF THE STUDY: A recent breast cancer genome-wide association study (GWAS) identified single-nucleotide polymorphism (SNP) rs2046210 on 6q25.1 showing a strong association with breast cancer risk. Numerous association studies have been conducted to investigate the relationship between this polymorphism and breast cancer risk in various populations. There have been conflicting reports about the association of this locus with breast cancer risk in different ethnic groups. For the first time, this study has investigated the association of rs2046210 SNP with breast cancer risk in Iranian Azari-Turkish women in North West Iran...

AIM OF THE STUDY: Decreased total antioxidant capacity (TAC) has been reported in different neoplasms, including lung cancer. However, no study concerning the relationship between endogenous antioxidants, lifestyle factors, and TAC has been conducted among lung cancer patients. The purpose of the study was to investigate the associations between endogenous antioxidants, severity of disease, lifestyle factors, and TAC in lung cancer patients. MATERIAL AND METHODS: The study was conducted among 59 lung cancer patients...

AIM OF THE STUDY: To characterise expression of mTOR (mammalian target of rapamycin) in childhood B-cell acute lymphoblastic leukaemia (ALL), and to evaluate a possible link between mTOR and clinical characteristics. MATERIAL AND METHODS: The examined group consisted of 21 consecutive patients, aged 1-18 years, diagnosed with B-cell ALL in 2010, and 10 relapsed B-cell ALL patients diagnosed for the first time between 2009 and 2011, who developed relapse before 2014...

Overall improvement in the nationwide system of medical services has consequently boosted the number of successfully treated patients who suffer from head and neck cancer. It is essential to effectively prevent development of radiation-induced caries as the late effect of radiation therapy. Incidence and severity of radiationinduced changes within the teeth individually vary depending on the patient's age, actual radiation dose, size of radiation exposure field, patient's general condition and additional risk factors...

Salivary gland tumours are a group of lesions whose heterogeneity of biological and pathological features is widely reflected in the molecular aspect. This is demonstrated by an increasing number of studies in the field of genetics of these tumours. The aim of this study was to collect the most significant scientific reports on the cytogenetic and molecular data concerning these tumours, which might facilitate the identification of potential biomarkers and therapeutic targets. The analysis covered 71 papers included in the PubMed database...

The metastasis-associated in colon cancer-1 (MACC1) gene was identified in 2009. Expression of MACC1 was found to be significantly upregulated in primary and metastatic colon carcinomas compared to normal tissues or adenomas. The induction of MACC1 occurs at the crucial step of transition from a benign to a malignant phenotype. The aim of this review was to summarise current results of non-clinical and clinical studies on the role of MACC1 in the carcinogenesis and progression of cancer, as well its potential therapeutic and prognostic significance...

Notch signalling is an evolutionarily conserved signalling pathway, which plays a significant role in a wide array of cellular processes including proliferation, differentiation, and apoptosis. Nevertheless, it must be noted that Notch is a binary cell fate determinant, and its overexpression has been described as oncogenic in a broad range of human malignancies. This finding led to interest in therapeutically targeting this pathway especially by the use of GSIs, which block the cleavage of Notch at the cell membrane and inhibit release of the transcriptionally active NotchIC subunit...

[(11)C]-choline is an effective PET tracer used for imaging of neoplastic lesions and metastases of the prostate cancer. However, its production can be a challenge for manufacturers, as it has not yet been described in Polish or European pharmacopoeia. In this study the technical aspects of [(11)C]-choline production are described and detailed process parameters are provided. The quality control procedures for releasing [(11)C]-choline as solutio iniectabilis are also presented. The purity and quality of the radiopharmaceutical obtained according to the proposed method were find to be high enough to safely administrate the radiopharmaceutical to patients...

AIM OF THE STUDY: Despite the increase in studies concerning oncoplastic reduction mammoplasty (ORM), data showing long-term aesthetic and patient satisfaction for ORM in patients with macromastia remain limited. Therefore, this study evaluated the long-term results of tumorectomy and concomitant bilateral ORM for early-stage breast cancer patients with macromastia in terms of cosmesis, patient satisfaction, and functional outcomes. MATERIAL AND METHODS: Retrospective data of patients with macromastia undergoing ORM for breast cancer between 1996 and 2011 were examined and evaluated regarding the aesthetic results, patient satisfaction, and functional outcomes...

INTRODUCTION: Although the recommended optimal treatment of glioblastoma multiforme (GBM) is adjuvant chemoradiotherapy, trials in GBM have excluded patients older than 70 years. In this study, we aimed to assess overall survival (OS) and prognostic factors in elderly patients (≥ 70 years) with newly diagnosed GBM treated with radiotherapy (RT) ± concurrent/adjuvant temozolomide (TMZ). MATERIAL AND METHODS: Inclusion criteria were patients ≥ 70 years, pre-RT Karnofsky performance status (KPS) ≥ 60, and time between diagnosis and start of RT ≤ 2 months...

AIM OF THE STUDY: To investigate the magnetic resonance imaging (MRI) features of skeletal muscle metastases (SMM). MATERIAL AND METHODS: The records of 31 patients with proven SMM were retrospectively reviewed. Clinical history, type of primary malignancy, location of metastases, and MRI features of SMM were evaluated. Based on MRI findings, SMM were divided into three MRI types. The correlation between MRI types with ages and pathology category, between MRI types of SMM and ages, as well as MRI types of SMM and pathology category were analysed with Spearman's rho...
