Abstract
OBJECTIVES Rectal neuroendocrine tumors (rNETs) are potentially malignant lesions. In our study, we aimed to retrospectively check whether the rectal neuroendocrine tumors were found in colonoscopy examinations carried out as a part of Polish colonoscopy screening program (PCSP). MATERIALS AND METHODS We retrospectively analyzed the colonoscopy and histopathological database of examinations conducted as a part of PCSP in our institution in the years 2005-2021. We also checked the method by which the tumor was removed, its characteristics based on photo documentations and followed up the patients. RESULTS The 10568 colonoscopy examinations were performed in PCSP in the years 2005-2021. Seven patients with a mean age of 53 with rNETs (1 in every 1510 colonoscopy) were detected. The polyp mean size was 5 mm. All the lesions were well differentiated tumors. First half of the colonoscopy examinations was performed in the years 2005-2012 and in that time three rNETs were detected, four rNETs were detected in the years 2012-2021. Even despite their typical appearance the neuroendocrine origin was not suspected in majority of cases and all tumors, except one, were removed with improper method. One of the patients underwent transanal endoscopic microsurgery of the scar. All patients are disease free in median follow-up of 108 months. CONCLUSION Rectal NETs are detected in the screening colonoscopy program. In majority of cases, they are not suspected by endoscopists on colonoscopy, but diagnosed after removal in histopathological examinations. There is a need of education of endoscopists in recognition and methods of treatment of rNETs.

Abstract
BACKGROUND Blastocystis sp. is a common intestinal protozoan found worldwide. Based on gene analysis, 17 subtypes (STs, ST1-ST17) have been identified, 9 of which have been isolated from humans. Differences in clinical consequences may depend on differences among the STs. Here, we evaluated the prevalence of Blastocystis sp. in patients with colorectal cancer (CRC) compared to a control group and assessed the relationships between Blastocystis sp. infection and sex; age; and CRC grade, stage, and location. METHODS The study included 107 CRC patients (41 women and 66 men, median age 65 years); 124 subjects without colorectal cancer or a history of oncological disease comprised the control group (55 women and 69 men, median age 63). Stool samples were collected from patients before oncological treatment and examined using light microscopy (iodine-stained smear). Additionally, PCR-based identification of Blastocystis sp. was performed in 95 stool samples from CRC patients and 76 stool samples from the control group. RESULTS Light microscopy showed that the prevalence of Blastocystis sp. was significantly higher in CRC patients than in the control group (12.15% and 2.42%, respectively; p = 0.0041). Multivariate analysis showed that the odds of Blastocystis sp. infection were fivefold higher in the CRC group than in the control group. PCR-based molecular examinations demonstrated that the proportion of patients infected with Blastocystis sp. was significantly higher in the CRC group than in the control group (12.63% and 2.63%, respectively; p = 0.023). The predominant ST in the CRC group was ST3, detected in nine patients (75%), followed by ST1 (2 patients, 16.7%) and ST2 (1 patient, 8.3%). No association was found between Blastocystis sp. infection and age, sex, or CRC stage, grade, or location. CONCLUSIONS The results showed that CRC was associated with an increased risk of opportunistic Blastocystis sp. infection, even before oncological treatment. To the best of our knowledge, this is the first report estimating the prevalence of Blastocystis sp. infection in CRC patients before oncological treatment in Europe.

Abstract
Transient or constant impaired immunity is often associated with neoplastic disease or oncological treatment. Among the most common pathogens found in patients with HIV or patients undergoing chemotherapy are protozoans of the Cryptosporidium genus, which cause diarrhea in humans and animals. The present study determined the frequency of Cryptosporidium spp. infections in patients with colorectal cancer (N = 108; 42 women; 66 men; median age, 65 years), before beginning oncological treatment, compared to a control group (N = 125; 56 women, 69 men; median age, 63 years) without colorectal cancer or a history of oncological disease. We also assessed whether Cryptosporidium spp. infections were associated with age, gender, cancer stage (based on Astler-Coller or TNM classification), histological grade, or cancer location. Patients were treated at the Pomeranian Medical University, in 2009-2014. The presence of Cryptosporidium spp. antigen was determined in stool samples, analyzed with a commercial immunoenzymatic test. Cryptosporidium spp. infections occurred significantly more often (p = 0.015) in patients (13%) compared to controls (4%). The patient group showed no significant relationship between Cryptosporidium spp. infection and sex, age, tumor location, cancer grade, or stage. A multivariate logistic regression analysis adjusted for age and sex that included all subjects (patient + control groups, n = 233) showed that the odds of a Cryptosporidium spp. infection were more than three-fold higher in patients than in controls, and more than six-fold higher among men than among women. CONCLUSIONS 1) Cryptosporidium spp. infections occurred significantly more frequently in patients with colorectal cancer (before oncological treatment) compared to controls, independent of age and sex. 2) Cryptosporidium spp. infections were not associated with the colorectal cancer stage, grade, or location or with patient age. 3) Male gender was significantly related to the frequency of Cryptosporidium spp. infections, independent of age and the presence of colorectal cancer.

Abstract
The correlation of thymidylate synthase (TS) expression in gastric cancers with tumor histology and prognostic or predictive information remains unclear. Most studies have involved Asian populations, with few conducted in European cohorts. Moreover, all published studies analyze TS expression using semi-quantitative methods. This retrospective study evaluated the association of TS expression in tumor cells with gastric carcinoma histological type, with selected clinicopathological parameters, and with the prognosis of patients who underwent surgical treatment. TS expression was detected using immunochemistry and objectively assessed by computerized image analysis of tumor cells in 100 gastric cancers. We found that high TS expression was significantly more common in intestinal than in diffuse type of gastric cancer according to Lauren classification (P=0.0003); in type I carcinomas compared to type IV according to Goseki classification (P=0.002); and in gastric cancers in men than women (P=0.04). Low TS expression was found more often in carcinomas in the middle and lower third of the stomach than in cancers in the upper third of the stomach (P=0.009 and P=0.001, respectively). In the subgroup of 25 patients without lymph node metastases (stage I+II), high TS expression was associated with better DFS (83% for high TS expression versus 38,5% for low TS expression, P=0.03). The results (1) indicate significant correlation between the Lauren and Goseki histopathological classifications of gastric cancer and TS expression in tumor cells, (2) suggest that high TS expression may be a positive prognostic marker with regard to DFS in patients with gastric cancer without involvement of regional lymph nodes who underwent radical surgical treatment and were not treated with preoperative chemotherapy. Prognostic results need confirmation in larger cohorts.

Abstract
The predictive value of thymidylate synthase (TS) expression alone for 5FU-based treatment of colorectal cancer (CRC) has not been clinically confirmed. Little is known on the association of expression of E2F1, which controls the transcription of genes encoding proteins engaged in DNA synthesis including TS, and survival of patients with CRC. The purpose of this study is to assess the correlation between expression of both E2F1 and TS in CRCs and survival of patients administered adjuvant 5FU-based chemotherapy, in order to find a better predictor of treatment outcome than expression of TS or E2F1 alone. Nuclear TS and E2F1 were detected by immunohistochemistry in tissue microarrays from 190 CRCs (Astler-Coller stage B2 or C). Multivariate analysis identified significant association of the combined E2F1+TS+ immunophenotype with worse OS (HR = 3,78, P = 0,009) and DFS (HR = 2,30, P = 0,03) of patients with colon cancer. There were significant differences between E2F1+TS+ and E2F1-TS- Kaplan-Meier survival curves in relation to DFS (P = 0.008) and OS (P = 0.01). About 37 and 31 % difference in 3-year DFS and OS respectively were seen between patients with E2F1+TS+ vs. E2F1-TS- colon cancer immunophenotype. The E2F1+TS+ immunophenotype may be a marker of poor prognosis (the worst DFS and OS) of patients with colon cancer treated with 5FU-based adjuvant therapy. A subgroup of patients with this immunophenotype may require different and perhaps more aggressive treatment than 5FU-based chemotherapy. Thus, the combined E2F1/TS immunophenotype could be a potential indicator of colon cancer sensitivity to 5FU.

Abstract
Data on prevalence and phenotypic consequences of nucleotide-binding oligomerisation domain 2/caspase recruitment domains 15 (NOD2/CARD15) variants in Crohn's disease (CD) population in Poland and Bosnia and Herzegovina (B&H) are nonexistent. We aimed to determine the prevalence of NOD2/CARD15 mutations and their association with disease phenotype in Polish and Bosnian patients with CD and in healthy controls. We prospectively recruited 86 CD patients and 83 controls in Poland and 30 CD patients and 30 controls in B&H, 229 in total. We determined the prevalence of NOD2/CARD15 mutations and their association with the disease phenotype according to Montreal classification. Participants were genotyped for Leu1007fsinsC and Gly908Arg mutations. At least one CD-associated allele was found in 29/86 (33.7%) of Polish CD patients and in 9/83 (10.8%) of healthy controls (p<0.001). In both CD patients and controls in Bosnian sample, at least one NOD2 mutation was found in equal number of patients (3/30; 10%) with all of the NOD2 mutation positive CD patients being homozygous, while controls being heterozygous. In Polish sample, perianal disease was less frequent in CD patients with any NOD2 mutation (1/21; 4.8%) compared to those without (11/41; 26.8%; p=0.046). Higher percentage of patients with NOD2 mutations had history of CD related surgery when compared with those without mutations (66.7% vs. 43.3%; p=0.05). The risk for CD is increased in patients with NOD2 mutations (Poland) and especially in the presence of homozygous NOD2 mutations (Poland and Bosnia). The presence of variant NOD2 alleles is associated with increased need for surgery and reduced occurrence of perianal disease.

Abstract
Background Studies on the expression of thymidylate synthase (TS) in colorectal cancers (CRCs) have failed to provide unequivocal prognostic or predictive information. Here, we assessed the prognostic significance of TS expression in Astler-Coller stage B2 and C CRCs defined by a p21WAF1/p53 immunophenotype in patients subjected to 5-fluorouracil (5FU)-based adjuvant therapy. Methods A cohort of 189 CRCs was asssessed for TS, p21WAF1 and p53 expression on tissue microarrays using immunohistochemistry, and associations with disease-free survival (DFS) and overall survival (OS) of the patients were assessed using univariate and multivariate analyses. Results TS expression led to the stratification of patients with colon cancer, but not rectal cancer, with immunophenotypes other than p21WAF1+/p53- (referred to as P&P) into subgroups characterized by a worse (P&P TS+) and a better (P&P TS-) DFS and OS, in univariate (P = 0.006 and P = 0.005, respectively) and multivariate (P = 0.0004 and P = 0.002, respectively) analyses. The p21WAF1+/p53- immunophenotype was associated with a favorable prognosis, irrespective of TS expression. Conclusions The strong association observed between the P&P TS+ immunophenotype and a worse DFS and OS suggests a predictive significance of TS expression for 5FU-based adjuvant therapy in patients with colon cancers exhibiting the P&P immunophenotype. In addition, our findings suggest that the appropriate target for assessment of TS expression as a prognostic/predictive marker is a subgroup of colon cancers with an immunophenotype other than p21WAF1+/p53-, and that only in this subgroup high TS expression is associated with an unfavorable DFS and OS. Therefore, we suggest that assessing TS expression in conjunction with p21WAF1/p53 immunophenotyping of colon cancers may improve the selection of patients suitable for 5FU-based adjuvant chemotherapy.

Abstract
Limited studies indicate a possible association of 5'-UTR thymidylate synthase enhancer region polymorphism and treatment outcome in patients medicated with 5-fluorouracil (5-FU). The study was designed to verify the relationship in patients with colorectal cancer (CRC), a Polish population that received 5-FU-based adjuvant chemotherapy. The study analyzed 145 Astler-Coller B2 and C CRC patients. Genotyping for a variable number of tandem repeats and G to C single-nucleotide polymorphism in the 5'-UTR of the thymidylate synthase (TS) gene was carried out. TS genotypes were classified into high expression (high TS) and low expression types (low TS). High TS was found in 22.8% of patients. The right-side tumors were more frequently associated with high TS than the left-side tumors (p=0.024). High TS was only found in 9.3% of rectal tumors, but in 29.7% of colon cancers (p=0.0042). Disease-free survival after 20 months (DFS 20) was longer in subjects with low TS than in high TS (p=0.043). Patients who underwent chemotherapy had longer DFS 20 in the low TS than in the high TS subgroup (p=0.051). The low TS was found to be an independent good prognostic factor for DFS 20 in the whole group as well as in the subgroup treated with chemotherapy (p=0.024 and p=0.034, respectively). Patients with low TS did not show any differences in DFS 20 whether they were treated with adjuvant chemotherapy or not. Proximal CRC tumors are characterized by higher TS expression genotypes than distal tumors, and are at significantly greater risk of early recurrence during the first 20 months after surgery.

Abstract
In several, but not all, previous studies, positive p21WAF1 expression has been suggested as an indicator of a good prognosis in patients with stage III/IV colorectal cancer. However, it is not known whether the same is true for stage B2 patients. The purpose of this study is to assess the influence of p21WAF1 expression in tumor cells on disease-free survival (DFS) and overall survival (OS) of Astler–Coller stage B2 and C patients with colorectal cancer who underwent 5-fluorouracil-based adjuvant chemotherapy. Nuclear p21WAF1 was detected by immunohistochemistry in tissue microarrays from 275 colorectal cancers. The expression of p21WAF1 was associated with DFS (p = 0.025) and OS (p = 0.008) in the subgroup of stage B2 patients that was treated with adjuvant chemotherapy. In multivariate analysis, it remained the only independent prognostic parameter in relation to DFS and OS (p = 0.035 and p = 0.02, respectively). In the subgroup of 72 stage B2 patients with positive p21WAF1 expression but not in the subgroup of 61 stage B2 patients with negative p21WAF1 expression, adjuvant chemotherapy was associated with better DFS (85% 5-year survival versus 65% without chemotherapy, p = 0.03) and OS (96% versus 82%, p = 0.014). In the combined stage B2 and C group of patients treated with adjuvant chemotherapy, positive p21WAF1 expression was also associated with better DFS and OS (p = 0.03, p = 0.002, respectively). Expression of p21WAF1 in colorectal tumor cells identifies a subgroup of Astler–Coller stage B2 patients who could benefit significantly from 5FU-based chemotherapy and may improve the selection of patients for adjuvant chemotherapy.

Abstract
INTRODUCTION Limited data is available regarding the relationships between cyclooxygenase-2 (COX-2) and colorectal cancer formation. OBJECTIVES The aim of the study was to investigate cyclooxygenase-2 (COX-2) expression in histologically diverse colonic polyps, to determine the association between the expression of this enzyme and selected patho logical and clinical characteristics of polyps, and to establish the location of cells with high COX-2 expression within the polyp. PATIENTS AND METHODS We examined 212 colonic polyps from 175 patients. Immunohistochemical staining with monoclonal anti-COX-2 antibodies was performed. RESULTS Statistically significant differences associated with high COX-2 expression were found: in adenomas vs. other polyps (P <0.001), in adenomas with high-grade dysplasia (P <0.000 001), and in polyps of the cecum (P <0.02). Statistically significant differences in COX-2 were also associated with polyp size (P <0.000 001). Cells with high COX-2 expression were usually located in the epithelial layer (P = 0.01). No significant associations were found between high COX-2 expression and the age and sex of patients or the total number of polyps. CONCLUSIONS We demonstrated that high COX-2 expression is associated with typical risk factors for malignant transformation of colonic polyps. The results suggest the possible role of COX-2 in the early stages of colon carcinogenesis.

Abstract
PURPOSE We aimed to study the intracellular expression of 5-lipoxygenase (5-LOX), the primary competitor with cyclooxygenase-2 in arachidonic acid metabolism, as inflammatory enzymes may be involved in blocking apoptosis and promoting cancer growth by changing arachidonic acid metabolism within cells. Our purpose was to investigate the possible connection between 5-LOX expression and colon carcinogenesis by characterizing 5-LOX expression in histologically different colonic adenomas, determining the relationship between high expression of 5-LOX and various conventional clinicopathological features of adenomas, and finally characterizing the histological localization of cells with 5-LOX overexpression. METHODS A total of 111 patients were examined and 120 histologically different colonic adenomas analyzed (including four cases of intramucosal adenocarcinoma in a polyp). Immunohistochemical staining with polyclonal anti-5-LOX antibodies was performed. RESULTS There was a significant correlation between high 5-LOX expression and patient age, increased polyp size, high grade of intraepithelial neoplasia, villous and tubulovillous adenoma, and histological epithelial localization. CONCLUSIONS We observed a strong positive correlation between 5-LOX overexpression and the appearance of typical high-risk factors for malignant transformation in adenomatous polyps. The results support the role of 5-LOX in early stages of colon carcinogenesis.

Abstract
OBJECTIVE Eradication of H. pylori is an important treatment strategy in peptic ulcer patients. Current regimens of eradication consist of proton pump inhibitor (PPI) and two antibiotics. Effects of PPI may depend on their metabolism, and other factors important for the pathophysiology of peptic ulcer disease. Aim of the present study was to evaluate an association of CYP2C19, MDR1, and IL-1B polymorphisms with the eradication rate of H. pylori in Polish Caucasian patients treated with a triple therapy of pantoprazole, amoxicillin, and metronidazole. METHODS A total of 139 peptic ulcer patients, positive for H. pylori infection, were treated with triple therapy (pantoprazole + amoxicillin + metronidazole). Subsequently, the patients were divided into two groups (group 1, success, and group 2, failure of eradication after therapy) and genotyped by the PCR-RFLP method for the presence of CYP2C19 variant alleles (*2, *3, and *17), and MDR1 3435C>T and IL-1B +3954C>T polymorphisms. Pantoprazole serum concentrations were measured using the HPLC method. RESULTS No significant differences in frequency or distribution of CYP2C19 genotypes were found between the two groups of patients (i.e., with successful H. pylori eradication and treatment failure). However, any carrier of defective CYP2C19*2/*2 genotype was found among patients with treatment failure. Similarly, MDR1 and IL-1B genotypes were found to be significantly associated with the success or failure of H. pylori eradication. Univariate and multivariate analysis of the genotypes did not reveal any significant association between the genotypes and H. pylori eradication. Pantoprazole concentrations differed significantly, and were the highest in patients with defective allele CYP2C19*2 carriers and lowest in hyperactive genotype homozygotes CYP2C19*17/*17. CONCLUSION The results suggest that the CYP2C19 genotype contrary to MDR1 and IL-1B genotypes may have an impact on the efficacy of H. pylori eradication in peptic ulcer patients treated with pantoprazole in Polish Caucasian peptic ulcer patients administered pantoprazole, amoxicillin, and metronidazole.

Abstract
Colorectal carcinoma (CRC) is a heterogeneous disease with specific epidemiological, pathological, molecular, and clinical characteristics that depend on the location of the tumor relative to the splenic flexure. Thymidylate synthase (TS) is a major target of 5-fluorouracil-based chemotherapy for CRC and high expression of this enzyme in tumor cells can influence the effect of therapy. We examined differences in TS protein expression in nuclei of tumor cells between CRCs located proximal and distal to the splenic flexure. Nuclear TS was detected by immunohistochemistry with a TS 106 monoclonal antibody on tissue microarrays constructed from 269 CRCs. The median histological score of nuclear TS expression of all proximal tumors was two times higher (p = 0.0003) and in men three times higher (p = 0.00023) than that found in distal tumors. In multivariate analysis which included age, sex, Astler-Coller stage, histological grade, and site, only proximal location of the tumor was identified as an independent factor associated with higher TS expression (odds ratio 2.46, 95% confidence interval = 1.29-4.70, p = 0.0062). These results demonstrate significant differences in nuclear TS expression between proximal and distal cancers and suggest the potential importance of the site of the tumor for proper stratification of patients for chemotherapy.

Abstract
DPYD gene encodes dihydropyrimidine dehydrogenase which is the initial and rate-limiting enzyme in the metabolism of 5-fluorouracil (5-FU). The aim of our study was PCR-RFLP based-genetic testing for the most common 5-FU toxicity-attributable IVS14 + 1G > A DPYD mutation (DPYD(*)2A) in 252 Polish colorectal cancer (CRC) patients treated with this adjuvant chemotherapeutic regimen after surgery. The DPYD(*)2A allele was identified only in one patient: a male who was one of 4 CRC patients suffering from grades 3-4 myelotoxicity upon 5-FU chemotherapy. We conclude that IVS14 + 1G > A DPYD (DPYD(*)2A) variant occurs in the Polish population and is responsible for a significant proportion of life-threatening toxicity of 5-FU.

Abstract
INTRODUCTION Little is known regarding the behaviour of serum anti-p53 antibodies (p53 Ab) in postoperative follow-up of patients with colorectal carcinoma and whether it can be used as an additional marker. The aim of this study was to evaluate usefulness of p53 Ab and CEA level for postoperative monitoring of recurrence or metastasis in patients after surgery due to colorectal cancer with normal pre-operative CEA levels and anti-p53 anitbodies. MATERIAL AND METHODS The research group consisted of 124 patients with colorectal cancer diagnosed on the basis of histopathological or cytological examination. Colonoscopy, abdominal ultrasound, serum CEA and anti-p53 antibody tests were done at the time of diagnosis and every 6-month from surgery. RESULTS The occurrence of recurrence or metastasis was preceded by the appearance of anti-p53 antibodies 6 months earlier on average, in 5 patients, and the increased CEA level was preceded 9 months earlier on average, in 7 patients. The relationship between the increased CEA level and the occurrence of recurrence or metastasis was statistically significant (p < 0.0001); however statistically significant relationship was not found in the case of anti-p53 antibodies assessment. Performing these two tests simultaneously, at the same time with the same patients caused the increase of accuracy of recurrence or metastasis from 0.45 to 0.68. CONCLUSION Multiple assessments of both serum p53 Ab and CEA during postoperative monitoring increase the probability of early detection of recurrence or metastasis in patients with colorectal cancer and normal CEA level before surgery.

Abstract
UNLABELLED Mutation of the p53 gene belongs to the most common genetic alteration in human cancer. Prognostic significance of serum anti-p53 antibodies in patients with gastric cancer is still a matter of controversy. The aim of the study was to estimate the presence of anti-p53 antibodies in serum of gastric cancer patients and relationship between anti-p53 antibodies and chosen clinical and pathomorphological data age, sex, localization of cancer, histology, stage of disease, metastases to lymph nodes and the time of survival. MATERIAL AND METHOD Serum samples from 71 patients with gastric cancer were analyzed by specific enzyme-linked immunosorbent assay (ELISA) to determine the presence of serum anti-p53 antibodies. The results were statistically compared with clinical and pathological features and postoperative survival. RESULTS Anti-p53 antibodies were detected in 16 (23%) gastric cancer patients. The presence of p53 antibodies was connected with intestinal tumor type (p < 0.05) and older age (p = 0.0035). There were no association between anti-p53 antibodies, stage and the time of survival. CONCLUSION These results suggest that in gastric cancer patients serum anti-p53 antibodies detected by ELISA are not predictor of prognosis.

Abstract
Parasitological examination of feces was carried out for 55 patients with diagnosed colorectal cancer before chemotherapy. Except for Cryptosporidium sp., no other intestinal parasites were found in the specimens; moreover, only the patients with watery diarrhea were Cryptosporidium sp.-positive by enzyme immunoassay. Prevalence of infection in the group of patients with diarrhea (23 persons) was 43.5%, whereas it was 18% for the entire group of patients under study. Coproantigens of this parasite were detected primarily in the patients with tumors located on the left side (in the sigmoid and descending colon).

Abstract
We report a case of a 34 year old women with spondylodiscitis due to Candida albicans infection. One and a half year earlier a ulcerative colitis she was diagnosed and treated with sulfasalazine, short course of glucocorticosteroids and with azathioprine. The diagnosis of fungal spondylodiscitis was made by culture of material collected from involved part of vertebral column during the surgery. Initially the patient was treated with fluconazole intravenously for 20 days, then the treatment was continued orally for one year. During the treatment all complaints disappeared and reduction of the laboratory acute phase indices was observed. Follow-up magnetic resonance's have shown gradual improvement. To our knowledge no similar case has been reported in the Polish literature before.

Abstract
Dieulafoy lesion may be one of the rare causes of acute gastrointestinal (GI) bleeding. This pathology mostly appears in the stomach wall, but very rarely it can be found in other parts of GI tract. Authors describe a case of 57-year-old female patient with a history of ulcerative colitis, staying in the complete remission since the moment of diagnosis many years ago, without any treatment. During the week before admission to the hospital, patient observed streaks of blood in the stool and felt some pain in the lower abdomen. On the day of admission to one of surgical departments in Szczecin, acute rectal bleeding had started in the patient, causing very serious state. The primary diagnosis was: rectal bleeding caused by a flare of ulcerative colitis. Sigmoidoscopy was performed in Gastroenterology Departament and it showed a vessel coming out of the rectal wall (like Dleulafoy lesion), with symptoms of active bleeding, while the mucosa was unchanged. The hemoclipping was performed and bleeding has been stopped. There was no recurrent bleeding.

Abstract
The difficulties in diagnosis of abdominal actinomycosis are presented. Clinical manifestations and colonoscopy suggested malignancy. Final diagnosis was made on the basis of pathological assessment of resected sigmoid. Authors underline that in case of "negative" pathomorphological results of material obtained during endoscopy from lesions suspected, benign disease should be consider including anctinomycosis and intraoperative pathomorphological examination should be performed.

Abstract
The purpose of this study was to correlate the presence of p53 antibodies in sera of patients with colorectal adenocarcinoma with size, site and stage of the tumour, age and sex of a patient and the level of carcinoembryonic antigen (CEA) in the serum. p53 antibodies were detected using enzyme-linked immunoabsorbent assay (ELISA). Serum p53 antibodies were detected in 30 of 145 patients (21%), mostly in Astler-Coller stage B1 (28% of patients). No association was found between p53 antibody status in stage A+B1+B2 vs stages C1+C2+D (22% vs 19%) i.e. between patients without and with metastases to regional lymph nodes and/or distant metastases. Serum p53 antibodies were detected in 9 of 34 patients (26%) with tumour localised in the right part vs 21 of 109 patients (19%) with tumours in the left part of the colon and in 18 of 96 (19%) of patients with tumours localised in rectosigmoideum vs 12 of 47 (26%) with tumours in the remaining colon. There was no significant correlation between serum anti p53 antibody and CEA statuses. Increased level of serum CEA was seen in 46/145 (32%) patients. Patients with C1+C2+D stage cancers had high serum CEA level more frequently than did patients with A+B1+B2 stage tumours (44% vs 19% respectively, p < 0.001). Of 102 cases with normal CEA level, 19 (19%) were positive for anti p53 antibodies. These results together with the literature data [11, 20] indicate that approximately 27% CEA negative patients may have serum p53 antibodies. Therefore simultaneous assessment of serum p53 antibodies and CEA seems to be useful for monitoring high risk patients and for postoperative patient monitoring.

Abstract
The frequency of the GSTM1 gene in patients with nonpolyposis colorectal cancer (CRC) (n = 70) and in subjects with colonic polyps (n = 27) was evaluated and compared with healthy individuals (n = 145). Patients with CRC were divided into the three groups: patients coming from the families with hereditary nonpolyposis colorectal cancer (HNPCC) (n = 17); patients with a high risk of HNPCC who were referred to as suspected of HNPCC (n = 25); patients with sporadic colorectal cancer without clinical features of hereditary tumours (n = 28). A simple polymerase chain reaction (PCR) - based assay to identify GSTM1 nulled and positive (non-nulled) genotype was used. No significant differences in frequency of nulled individuals were observed in both patients with HNPCC and patients suspected of HNPCC as well as in subjects with colonic polyps. The most interesting observation was made in the group of patients with sporadic CRC. Twenty individuals (71.4 %) of the group were GSTM 1 deficient which was significantly different from the control population (p < 0.04). The above data indicate that the absence of the GSTM1 gene is associated with a greater risk of sporadic colorectal cancer. There is an increase in the overall risk of approximately 2.5 as compared with the control population.

Abstract
The retrospective flow cytometric analysis of 54 colorectal adenomatous polyps resected endoscopically from 43 patients was performed. The aim of the study, with the use of flow cytometry was to determine, DNA ploidy and proliferative activity of epithelial cells in a series of adenomas and to compare the results with classical histopathological criteria. Overall 30 tubular and 19 tubulo-villous/villous adenomas with different grade of dysplasia as well as 5 adenomatous polyps with carcinoma in situ (CIS) were examined. DNA aneuploidy was found in 4 of 54 polyps (7.4%), all with histological features of CIS. Proliferation rate increased significantly with the degree of dysplasia (9.0 +/- 3.1%; 16.3 +/- 4.3%; 22.1 +/- 4.1% in adenomas with mild, moderate and severe dysplasia respectively; p < 0.05). No significant differences in cell proliferative activity were found between groups of adenomas as compared to histological type and size. The results show that cell proliferative activity in colorectal adenomatous polyps depends strongly on the grade of dysplasia and does not show such a direct association with respect to histological type or size of adenomas. It may be concluded as well that DNA aneuploidy precedes histological changes of invasive carcinoma in colorectal adenomas and therefore flow cytometric DNA analysis may be of great value in defining more accurately the biological stage of neoplasmatic process in individual cases.

Abstract
In eight patients (two women and six men) aged from 31 to 80 years, extensive resection of the small intestine had been performed before many years. The most frequent causes of the operation were thrombosis and embolism of the superior mesenteric artery (three cases each). In all patients the small intestine was resected, at least partially, and in two patients also hemicolectomy with resection of Bauhin valve was performed. The most frequent complaint reported by the patients is periodical diarrhoea which becomes more intense particularly after fat consumption. Laboratory investigations and absorption tests were carried out in the patients at least one year after the operation. In all patients impaired absorption and hypoalbuminaemia were found. No significant correlation was found between the extent and time after the resection and the degree of intensity of the observed abnormalities.

Abstract
The proliferative activity of crypt epithelial cells was studied in 64 duodenal biopsies using immunohistochemistry and proliferating cell nuclear antigen (PCNA)/cyclin monoclonal antibodies in alcohol-fixed paraffin-embedded sections. A positive correlation between duodenitis as defined by histological criteria and increased mean percentage of PCNA positive crypt cell nuclei (PCNA index) was found. The mean PCNA index in normal mucosa was 11.8 +/- 2.7% (mean +/- SD), in mild (grade 1) duodenitis 17.3 +/- 3.9%, in moderate (grade 2) 30.6 +/- 6.9%, and in severe (grade 3) duodenitis 41.1 +/- 8.5%. The inclusion of PCNA index, which is easily measured in paraffin-embedded sections, in the existing histopathological grading systems of duodenitis may improve their clinical relevance.

Abstract
In the last decade, the primary, biliary liver cirrhosis was diagnosed in 17 female patients aged between 33 and 72 years. The most frequent complaint were itching and jaundice. Hepatomegaly and itching predominated in the clinical signs Laboratory tests have shown and increase in alkaline phosphatase activity, gamma-glutamyltranspeptidase, and alanine-aminotransferase activities, accelerated ESR and decrease in blood serum albumins. Immunological abnormalities were found in 15 patients, including 12 with antimitochondrial antibodies. Liver biopsy was carried out in all patients enabling to diagnose the primary cirrhosis in 14 of them. Duration of the disease was between 1 and 9 years. Immunosuppressive treatment was carried out in 10 patients, and symptomatic treatment in the remaining 7 patients. No difference in the effect of therapy on actual health state of patients was seen.
