Abstract:The study objective was to determine the presence of MMP-7 in cancer tissue in correlation with its serum level in patients diagnosed with colorectal cancer (CRC). In 45 patients with CRC, MMP-7 expression was assessed immunohistochemically on FFPE slides in tumours (N = 37) and in the corresponding surgical margin sample. MMP-7 serum level was measured preoperatively. The expression of MMP-7 in cancer tissue was much stronger as compared to the normal intestinal mucosa. Also the level of MMP-7 in the serum of CRC patients was higher than in healthy subjects (N = 24) (p < 0.01). The tumour located in the colon showed higher expression of MMP-7 than CRCs located in the rectum (p < 0.05), whereas the higher MMP-7 serum level showed correlation with older age (p = 0.005), tumour size less than 5 cm (p < 0.05), higher Dukes' stage (p < 0.05) and distant metastases (p < 0.05). The increased serum level of MMP-7 in CRC patients may indicate the presence of distant metastases.
Abstract:The incidence of malignant gastrointestinal cancers in Poland has been constantly growing, which has led to an intensification of the search for new markers of the early clinical stage of this disease. The oral cavity, as the first part of the gastrointestinal tract, has a very important role. The oral cavity presents symptoms of both typically stomatological and systemic diseases. Oral cancers, benign or malignant, may originate and grow in any of the tissues of the mouth, and within this small area they may be of varied clinical, histological and biological features. These can be lesions typically observed in the oral cavity, but also characteristic of cases where the symptoms occur both in the mouth and in other body parts. The aim of this study was to present a cytological picture of the oral mucosa in patients with gastric and colon cancer and to compare the cytological picture with that obtained from a group of patients with no cancer, using the Papanicolaou classification and the Bethesda system. The study was conducted in 126 patients treated surgically in the II General and Gastroenterological Surgery Clinic between 2006 and 2008. All patients were divided into two groups based on the type of lesions. In both of the studied groups, more than half of the patients did not present any abnormalities in the mucosa of the mouth, lips and cheeks in the physical examination. None of the patients had erosion, ulceration or lesions typical of leukoplakia or lichen planus. No malignant cells were detected in either of the studied groups, and there were no well-defined lesions found in the oral cavity that would distinguish the patients with gastrointestinal cancer.

Introduction: The aim of this study was to analyze the technical evaluation of cervicovaginal smears as well as the correlation of the technical quality of the smear with the patient’s age. Materials and methods: The study included a group of 43,696 women who underwent exfoliative cytology. The smears were stained according to the Papanicolaou method and then underwent cytological evaluation based on the Bethesda system. Results: The technical quality of the cytology smears was found to be satisfactory (AI) in 80.6% of cases, acceptable for cytological evaluation (AII) in 19% mainly as a result of poor readability of the smear due to numerous inflammatory cells (35.5%), whereas not suitable for evaluation (AIII) was in 0.4% of cases. Moreover, there was a high proportion of smears without cells from the cervical canal in women under 50 years of age. In women over 50, the most common cause of conditional evaluation of the smear was its excessive dryness Conclusions: In all age groups, an abundance of inflammatory cells was a factor that hindered cytologic evaluation of the smear. Only representative material containing cells from the cervical canal should be collected. It is of utmost importance to pay special attention to the correct and quick fixation of smears taken from women over 50 years of age.
The analysis of the late publications is evidence of the tendency to the rising rectal cancer incidence in the whole world. According to the data of World Health Organization every year more than 500 thousand cases of this disease are registered in the world. In the structure of oncologic incidence rate rectal cancer takes the second-third place in both men and women and goes second among the oncopathology death reasons in the majority of economically developed countries. The adenomatous polypi are known to develop the majority of rectal neoplasms. The chain «adenoma - cancer» has been proved by numerous researches and though not every adenoma tranforms into cancer, this is possible in a considerable number of the present neoplasms. In connection with this, the endoscopic diagnosis and ablation of adenomatous polypi of rectum and large intestine are effective methods of rectal cancer prophylaxis.
