<b>Introduction:</b> Colorectal cancer is one of the most common cancers occurring in Poland. Unfortunately, this cancer is most often diagnosed at the time of great advancement. This is caused by the appearance of specific symptoms only in the late stages of cancer. Also, such low detection of early stages of adenocarcinoma may be caused by disregarding of slight symptoms. <br/>Purpose:</b> To analyse symptoms in patients with colorectal cancer and correlate with chosen clinical-pathological parameters. <br/>Materials and methods:</b> The study group consisted of 46 patients diagnosed with colorectal cancer. Information on symptoms associated with cancer (subjective and objective) have been selected from patients' medical history. The presence of these symptoms was correlated with the age and sex of patients, tumor location, histological type of cancer, grade of histological malignancy (G), stage of tumor (T stage), presence of lymph node metastases and distant metastases. <br/><b>Results:</b> It has been shown that the presence of pain complaints described by the patient are associated with the occurrence of cancer in the colon. The painfulness and pathological resistance diagnosed by the physician are more often associated with cancer located in the colon. In the case of tumors located in the rectum, faecal admixtures appear more frequently. It has also been shown that the presence of admixtures of blood and mucus in the stool is associated with more advanced local tumors, infiltrating pericolorectal tissues (T3 + T4). <br/><b>Conclusions:</b> Familiarity with clinical symptoms of colorectal cancer could make patients more sensitive to more often screening for cancer. Analysis of these symptoms could indicate to the physician the location or stage of the cancer.

Introduction/Objective. The aim of this study is to examine the association of E-cadherin expression and high proliferation index (proIDX) with clinical and pathological indicators of colorectal cancer progression. Methods. The biopsy of 72 patients, obtained by resection of colorectal cancer, was routinely processed at the Institute of Pathology of the Clinical Centre of Montenegro, embedded in paraffin and archived. Based on the archived pathohistological reports, two study groups were formed: the first group (n = 72) consisted of operative biopsies of colorectal cancer, and the control group (n = 72) consisted of biopsies of adjacent non-tumor tissue. Routine hematoxylin-eosin and immunohistochemical ABC method with anti-Ki67 and anti-E-cadherin antibodies was applied on. After quantification of the results for statistical tests, the software package SPSS for Windows (19.0) was used. Results. In colorectal carcinoma, we observed a significant association of proIDX with pT stage, lymph and blood vessel invasion, perineural invasion, lymph node metastases and distant metastases, and Astler-Coller stage tumor disease. We also observed that the absence of E-cadherin was significantly associated with pT stage, lymph and blood vessel invasion, perineural invasion with lymph node metastases, distant metastases, with C2 and D Astler-Coller tumor stage. E-cadherin expression is associated with proIDX with a significantly high, negative correlation coefficient. Conclusion. Our results indicate that it is possible to differentiate patients into groups with a higher or lower risk of developing metastatic disease, based on the expression of Ki67 and E-cadherin.

ABSTRACT Objective: to study the epidemiological profile of patients with colorectal cancer operated on an emergency basis at the Bonsucesso Federal Hospital. Methods: this is a retrospective study of patients operated between January 1999 and December 2012. We analyzed the following variables: age, gender, clinical data, TMN staging, tumor location, survival and types of surgery. Results: we evaluated 130 patients in the study period. The most frequent clinical picture was intestinal obstruction, in 78% of cases. Intestinal perforation was the surgical indication in 15%. The majority (39%) of the patients had advanced TNM staging, compared with 27% in the initial stage. There were 39 deaths (30%) documented in the period. The most common tumor site was the sigmoid colon (51%), followed by the ascending colon (16%). The curative intent was performed in most cases, with adjuvant treatment being performed in 40% of the patients. Distant metastases were found in 42% of the patients and 10% had documented disease recurrence. Disease-free survival at two and five years was 69% and 41%, respectively. Conclusion: there was a high mortality rate and a low survival rate in colorectal cancer patients operated on urgently.

Mitochondrial Microsatellite Instability

This study attempts to determine whether primary tumor tissue could reliably represent metastatic colorectal cancer in therapy-guiding analysis of mitochondrial microsatellite instability. Therefore, we investigated the concordance of microsatellite instability in D310, D514, and D16184 (mitochondrial DNA displacement loop), and its association with selected clinical categories and KRAS/NRAS/BRAF/PIK3CA/TP53 mutation status between primary and metastatic colorectal cancer tissue from 119 patients. Displacement loop microsatellite instability was significantly more frequently seen in lymph node metastases (53.1%) compared to primary tumors (37.5%) and distant metastases (21.4%) ( p = 0.0183 and p = 0.0005). The discordant rate was significantly higher in lymph node metastases/primary tumor pairs (74.6%) than in distant metastases/primary tumor pairs (52.4%) or lymph node metastases/distant metastases pairs (51.6%) ( p = 0.0113 and p = 0.0261) with more gain (86.7%) than loss (61.1%) of microsatellite instability in the discordant lymph node metastases ( p = 0.0024). Displacement loop instability occurred significantly more frequently in lymph node metastases and distant metastases of patients with early colorectal cancer onset age <60 years ( p = 0.0122 and p = 0.0129), was found with a significant high rate in a small cohort of TP53-mutated distant metastases ( p = 0.0418), and was associated with TP53 wild-type status of primary tumors ( p = 0.0009), but did not correlate with KRAS, NRAS, BRAF, or PIK3CA mutations. In conclusion, mitochondrial microsatellite instability and its association with selected clinical and molecular markers are discordant in primary and metastatic colorectal cancer, which could have importance for surveillance and therapeutic strategies.

Background and objectives: T regulatory lymphocytes (Treg) are one of the subsets of T-lymphocytes involved in the interaction of neoplastic tumors and the host immune system, and they may impair the immune reaction against cancer. It has been shown that Treg are increased in the peripheral blood of patients with various cancers. In colorectal cancer, the prognostic role of Treg remains controversial. Colorectal cancer is a heterogenous disease, with many variations stemming from its primary tumor location. The aim of this study is to analyse the relationship between the amount of Treg in the peripheral blood of patients with left-sided colorectal cancer in various stages of disease and long-term survival. Materials and Methods: A prospective analysis of 94 patients with left-sided colorectal cancer and a group of 21 healthy volunteers was carried out. Treg levels in peripheral blood were analysed using flow cytometry. Results: There was a statistically significant difference between the amount of Treg in the Ist and IInd TNM stages (p = 0.047). The number of Treg in the entire study group was significantly lower than in the control group (p = 0.008) and between patients in stages II and III and the control group (p = 0.003 and p = 0.018). The group of pT3+pT4 patients also had significantly lower Treg counts in their peripheral blood than the control group (p = 0.005). In the entire study group, the level of Treg cells in the peripheral blood had no influence on survival. The analysis of the TNM stage subgroups also showed no difference in survival between patients with “low” and “high” Treg counts. Conclusion: The absolute number of Treg in the peripheral blood of patients with left-sided colorectal cancer was significantly decreased in comparison to healthy controls, especially for patients with stage II+III disease. Treg presence in the peripheral blood had no impact on survival.

Scrub typhus (Orientia tsutsugamushi), is a strict intracellular bacterium which is reported to be a recent threat to parts of southern India. There is re-emergence of scrub typhus during the past few years in Chennai. Scrub typhus is an acute febrile illness which generally causes non-specific symptoms and signs. The clinical manifestations of this disease range from sub-clinical disease to organ failure to fatal disease. This study documents our laboratory experience in diagnosis of scrub typhus in patients with fever and suspected clinical symptoms of scrub typhus infection for a period of two years from April 2014 to April 2016 using immunochromatography and IgM ELISA methods. The study was conducted on 648 patients out of whom 188 patients were found to be positive for scrub typhus. Results also showed that pediatric (0 -12 years) and young adults (20 – 39 years) were more exposed to scrub typhus infection and female patients were more infected compared to male. The study also showed that the rate of infection was higher between September to February which also suggested that the infection rate is proportional to the climatic condition. Statistical analysis showed that the mean age of the patients in this study was 37.6, standard deviation was 18.97, CV % was 50.45.

BACKGROUND To develop websites that enhance Internet users’ health knowledge, it is important to identify relevant factors associated with obtaining health knowledge via the Internet. Although an association between eHealth literacy (eHL) and knowledge of colorectal cancer (CRC) has been reported, little is known whether eHL is associated with obtaining knowledge of CRC via the Internet. OBJECTIVE This study aimed to compare the results obtained from Internet users with high or low eHL in searching and using a reputable cancer website to gain CRC knowledge. METHODS This study used respondents to Internet based pre-and post-surveys conducted in 2012. Potential respondents (n = 3,307) were identified from registered individuals aged 40–59 years (n = 461,160) in a Japanese Internet survey company. A total of 1,069 participants responded (response rate: 32.3%), and these pre-survey responders were then divided into high or low eHL groups using the Japanese eHealth Literacy Scale median score (23.5 points). From each group, 130 randomly selected individuals were invited to review the contents of a reputable CRC website, the Cancer Information Service managed by the National Cancer Center, and to respond to a post-survey via e-mail; responses were obtained from 107 individuals from each group. Twenty responses to knowledge statements regarding the definition, risk factors, screening prevention and symptoms of CRC were obtained at pre- and post-surveys, and differences in the correct responses between high and low eHL groups compared using the McNemar test. RESULTS The mean age of the participants was 49.1 (5.5) years. Four statements showed a significant increase in correct responses in both eHL groups pre- and post-survey: “S4. The risk of CRC is greater as a person gets older” (high eHL: P = 0.039, low eHL: P = 0.012), “S8. Cigarette smoking is a risk factor for CRC” (high eHL: P < 0.001, low eHL: P = 0.020), “S11. Obesity is a risk factor for CRC” (high eHL: P = 0.030, low eHL: P = 0.047), and “S12. Excess alcohol consumption is a risk factor for CRC” (high eHL: P = 0.002, low eHL: P = 0.003). Three statements showed a statistically significant increase in correct responses in the high eHL group only: “S1. CRC is cancer of the colon or rectum” (P = 0.003), “S5. The risk of CRC is the same between men and women” (P = 0.041), and “S9. Red meat intake is a risk factor for CRC” (P = 0.002), whereas only one response did in the low eHL group: “S17. Bloody stools are a symptom of CRC” (P = 0.004). CONCLUSIONS Low eHL Internet users appeared less capable of obtaining knowledge of CRC through searching and understanding information from a reputable cancer website than high eHL Internet users.

Abstractwas to assess patients’ awareness of the prevention and treatment of colorectal cancer.Patients diagnosed with colorectal cancer, hospitalised at the Department of General and Colorectal Surgery of the Medical University in Łódź during the period from January 2015 to April 2015, were asked to complete a questionnaire concerning their families’ medical case record, factors predisposing them to the development of colorectal cancer, the tests applied in diagnostics, and the treatment process. The questionnaire comprised 42 closed-ended questions with one correct answer. A statistical analysis of all answers was carried out.The study group consisted of 30 men and 20 women aged 27–94 years old. A strong, statistically significant negative correlation between a patient’s age and his/her awareness of the prevention and treatment of colorectal cancer was noted (p<0.001; r= −0.51). The study demonstrated a statistically significant relationship between the occurrence of neoplasms in a patient’s family (p=0.009) or, more specifically, the occurrence of colorectal cancer (p=0.008), and the awareness of the prevention programme. The women’s group was characterised by statistically significantly greater awareness of colonoscopy as a screening examination (p=0.004).Patients need more information on colorectal cancer, its risk factors, prevention, the treatment process, and postoperative care. Lack of awareness of the colorectal cancer issue can be one of the major factors contributing to the high incidence of this disease.

Abstract Background The identification of the homogeneous and heterogeneous risk factors for different types of metastases in colorectal cancer (CRC) may shed light on the aetiology and help individualize prophylactic treatment. The present study characterized the incidence differences and identified the homogeneous and heterogeneous risk factors associated with distant metastases in CRC. Methods CRC patients registered in the SEER database between 2010 and 2016 were included in this study. Logistic regression was used to analyse homogeneous and heterogeneous risk factors for the occurrence of different types of metastases. Nomograms were constructed to predict the risk for developing metastases, and the performance was quantitatively assessed using the receiver operating characteristics (ROC) curve and calibration curve. Results A total of 204,595 eligible CRC patients were included in our study, and 17.07% of them had distant metastases. The overall incidences of liver metastases, lung metastases, bone metastases, and brain metastases were 15.34%, 5.22%, 1.26%, and 0.29%, respectively. The incidence of distant metastases differed by age, gender, and the original CRC sites. Poorly differentiated grade, more lymphatic metastasis, higher carcinoembryonic antigen (CEA), and different metastatic organs were all positively associated with four patterns of metastases. In contrast, age, sex, race, insurance status, position, and T stage were heterogeneously associated with metastases. The calibration and ROC curves exhibited good performance for predicting distant metastases. Conclusions The incidence of distant metastases in CRC exhibited distinct differences, and the patients had homogeneous and heterogeneous associated risk factors. Although limited risk factors were included in the present study, the established nomogram showed good prediction performance.
