OBJECTIVE: To identify the frequency of Internet use by colorectal cancer patients. MATERIALS AND METHODS: Fifty patients interviews. RESULTS: Only four patients (8%) had used the internet to access information about colorectal cancer though 36% would have used it if a site had been recommended. CONCLUSION: The Internet is a resource rarely used by patients but there is potential for its use as an adjunct to written and verbal information. 相似文献

Objective The Internet provides an enormous amount of patient‐orientated information on colorectal cancer. This study examined its accessibility and quality. Methods Sites were identified using two search engines (Google and Hotbot) and the search terms ‘bowel cancer’ and ‘colon and rectal cancer’. The first 100 sites in each search were visited and classified. Sites that contained patient information were assessed using the ‘Discern’ instrument for reliability and quality of information on treatment choices. Results Google identified 55 700 sites for the search term ‘colorectal cancer’ and 214 000 for ‘bowel cancer’. Hotbot produced 27 700 and 190,000, respectively. Four hundred sites were studied. Only 25 (6%) sites were duplicated in the searches. One hundred and eighteen (30%) provided information, 70 (18%) were lists of links, 27 (7%) were adverts, 22 (6%) promoted medical centres, 51 (13%) were dead links, 15 (4%) were message boards. Of the 118 that provided information 73 (62%) advised on treatment and 73 (62%) were designed for patients. The sources of information were clear in 55 (47%) and the date when this information was reported was given in only 63 (53%). By adapting the Discern instrument, sites were classified as excellent 18 (15.3%), very good 19 (16.1%), good 28 (23.7%), fair 8 (6.8%) and poor 45 (38.1%). Conclusions The Internet provides a wealth of information on colorectal cancer but the best sites are difficult for patients to distinguish from the thousands of sites returned by search engines. Clinicians should guide patients to quality sites to avoid confusion and misinformation. 相似文献

Background
Colorectal cancer is diagnosed in approximately 500,000 patients each year in Europe, leading to a high number of patients having to cope with the consequences of resection for colorectal cancer. As treatment options tend to grow, more information on the effects of these treatments is needed to engage in shared decision-making. This study aims to explore the impact of resection for colorectal cancer on patients' daily life.Methods
Patients (≥18 years of age) who underwent an oncological colorectal resection between 2018 and 2021 were selected. Purposeful sampling was used to include patients who differed in age, comorbidity conditions, types of (neo)adjuvant therapy, postoperative complications and the presence/absence of a stoma. Semi-structured interviews were conducted, guided by a topic guide. Interviews were fully transcribed and subsequently thematically analysed using the framework approach. Analyses were carried out using the following predefined themes: (1) daily life and activities; (2) psychological functioning; (3) social functioning; (4) sexual functioning; and (5) healthcare experiences.Results
Sixteen patients with a follow-up period of between 0.6 and 4.4 years after surgery were included in this study. Participants reported several challenges experienced because of poor bowel function, a stoma, chemotherapy-induced neuropathy, fear of recurrence and sexual dysfunction. However, they reported these as not interfering much with daily life.Conclusion
Colorectal cancer treatment leads to several challenges and treatment-related health deficits. This is often not recognized by generic patient-reported outcome measures, but the findings on treatment-related health deficits presented in this study contain valuable insights which might contribute to improving colorectal cancer care, shared decision making and value-based health care. 相似文献4.

Objective The objective of this study was to evaluate the effectiveness of the internet as a source of information for colorectal cancer (CRC). Method Six of the most common search engines (Yahoo, Google, MSN search, Alta Vista, Excite and Lycos) were used for the search of the generic term ‘CRC’. First 300 links were analysed and classified by information type, provider, readership and commercial orientation. Results The average time delay was 1.70 s before matches were located. A total of 3.2827 million matches on CRC were found using the six search engines ranging from 700 (Excite) to 1 417 000 (Lycos) websites. Approximately 50% of the links were based on information from textbooks or governmental websites. Commercial companies giving information about private hospitals and products provided over 50% of the websites on CRC. The distribution of target readers was uneven, although a majority of websites were delivering CRC information to public and patients. Readability of information was difficult to comprehend by the public. Conclusion The internet is becoming an essential tool for disseminating information about CRC to consumers. Half of the links on CRC are commercially oriented, containing information on goods or private health services. Less than 1% information is being provided by professional societies. To provide relevant CRC information, key consensus criteria for evaluating healthcare‐related websites have to be established. There is an urgent need for CRC information on the internet to be regulated through the establishment of government‐funded organizations (e.g. NHS) or professional societies (e.g. ACPGBI). 相似文献

Objective The assessment of family history and medical data is crucial in identifying families with Lynch syndrome (LS). Among consecutive colorectal cancer (CRC) patients, we aimed at identifying all patients with a hereditary predisposition, and to study a possible discrepancy with assessments made by the responsible clinicians.
Method All consecutively diagnosed patients with CRC from two Norwegian hospitals were included, and information on family history was collected in a detailed interview. We assessed information in medical records, and tumours were examined for LS-associated histopathological features.
Results Among 562 patients, there was no documentation of family history in 388 (69.0%) medical records, and in 174 (31.0%) patients, there was no clinical assessment of the information that was collected on family history. Based on detailed interviews and extended pathological examination, we found that 137 (24.4%) of the 562 patients could be classified as possible LS according to the Revised Bethesda Guidelines (RBG); and that 46 (33.6%) of these patients could be identified by family history alone.
Conclusion Family history and relevant information in patient records can identify patients with possible LS. However, clinicians often fail to include information on hereditary factors and to assess relevant data in medical records. Familial CRC is therefore not acknowledged, and genetic counselling is not offered. 相似文献

Objective The aim of the study was to evaluate the changing influence of age on the outcomes of colorectal cancer surgery in a retrospective trend analysis.
Methods Data on 985 patients undergoing colorectal cancer surgery were collected during 1975–1984 and 1995–2004. Variables and outcomes of patients aged < 65, 65–74, 75–84 and 85+ years were compared with intra- and interdecade analyses. Endpoints of the study were postoperative mortality, 5-year overall and cancer-related survivals.
Results The rate of elderly patients undergoing colorectal cancer surgery increased significantly from 1975–1984 to 1995–2004. Distribution of American Society of Anesthesiology score and cancer stage remained unchanged over time. The rate of palliative procedures decreased over time, most significantly in the older age groups. In 1995–2004 the palliation rate was similar across all age groups. The rate of emergency surgery also decreased, but it remained higher in older age groups. Operative mortality rate decreased over time across all age groups, but age-related differences were still observed in the 1995–2004 series. Cancer-related survival after curative surgery increased from 58% in 1975–1984 to 64% in 1995–2004 in 75+ years patients, while it increased from 56% to 78% in patients aged 74 years or younger.
Conclusions Elderly patients with colorectal cancer benefited substantially from healthcare progress during the last 30 years. The reduction of palliative procedures and the decline in operative mortality document the efficacy of not restricting the access to radical surgery for these patients. 相似文献

Endoscopic Submucosal Dissection (ESD) is a technique developed in Japan for “en bloc” resection of larger superficial neoplasms of the gastrointestinal tract as an alternative to the traditional Endoscopic Mucosal Resection (EMR), with removal of the lesion in multiple fragments (“piecemeal”). ESD offers a lower recurrence rate and allows a more accurate histopathological examination. This procedure is however considered technically difficult and therefore requires an adequate learning curve, it is time consuming with more discomfort for the patient, it has a higher complication rate, it is more expensive. To overcome these disadvantages, in the Western countries a hybrid technique called Circumferential Submucosal Incision - Endoscopic Mucosal Resection (CSI-EMR) has been developed and is especially employed for colonic lesions.This article analyzes retrospectively the results obtained in a single centre by a single operator in the treatment of 23 patients (12 men and 11 women, average age 65,6 years), all suffering from superficial, larger than ≥ 20 mm colorectal neoplasms: 9 were treated with ESD for rectal lesions and 14 were treated with CSI-EMR for colonic lesions.Findings show a technical success rate of 66,6% for ESD and 78,5% for CSI-EM, and a 0% recurrence rate during follow-up, 4,3% bleeding and 13% perforation complications. The histology of the removed lesions showed 13 (56,5%) low grade dysplasia adenomas, 8 (34,7%) high grade dysplasia adenomas, one grade 1 sigmoid colon adenocarcinoma infiltrating the submucosal layer without lymphovascular invasion, with free margins (R0), treated conservatively, and one grade 1 cecum adenocarcinoma, infiltrating the submucosal layer, with lymphovascular invasion and involved excision margin, treated surgically with no residual neoplastic disease in the surgical specimen.These data are in line with the most significant ones in literature, except for the higher complication rate, which the authors ascribe to the “learning curve” and the smaller number of treated patients. 相似文献

Modulators of ceramide metabolism sensitize colorectal cancer cells to chemotherapy: A novel treatment strategy 总被引:10,自引:0,他引:10

Irinotecan is a first-line chemotherapeutic agent for patients with metastatic colorectal cancer (CRC). Response rates of
less than 40% underscore the problem of treating CRC with irinotecan. Our studies have shown that chemosensitization correlates
with high levels of ceramide, whereas resistance correlates with high levels of glucosylceramide (GlcCer). The purpose of
this study was to characterize the role of ceramide in irinotecan-mediated CRC cell death. We used four human CRC cell lines
to assess ceramide metabolism, cell viability, and apoptosis after treatment with irinotecan. Fumonisin B1 (FB1) and 1-phenyl-2-palmitoylamino-3-morpholino-1-propanol
(PPMP) were used to inhibit de novo ceramide synthesis and GlcCer production, respectively. L-threo-dihydrosphingosine (safingol)
was used to inhibit secondary proliferative pathways mediated by an atypical protein kinase C that is activated by ceramide.
Irinotecan elicited dose- and time-dependent increases in ceramide, which preceded apoptosis. When FB1 was added to irinotecan,
CRC cell death was significantly decreased. A significant increase in intracellular levels of GlcCer also was noted after
treatment with irinotecan. When GlcCer production was blocked by treating cells with PPMP in addition to irinotecan, ceramide
levels increased to 228% of control values and cell death increased by 88%, compared to irinotecan alone. When irinotecan
was combined with both PPMP and safingol, cell death was increased by 225% to 325%, compared to irinotecan lone. CRC cell
death due to irinotecan is mediated, at least in part, by the de novo synthesis of ceramide. Blocking further metabolism of
ceramide can enhance this cytotoxicity. Targeting ceramide pathways is a novel strategy for the treatment of patients with
CRC.

To assess the impact of a stoma on surgical site wound infection in colorectal cancer, we conducted a meta-analysis. A thorough review of the literature up to September 2022 revealed that 3223 participants had colorectal cancer at the start of the investigations; 258 of them had a stoma, while 2965 did not have a stoma. Using dichotomous or contentious methods and a random or fixed-effect model, odds ratios (OR) and mean difference (MD) with 95% confidence intervals (CIs) were estimated to evaluate the impact of a stoma on surgical site wound infection in colorectal cancer. The stoma present had significantly higher surgical site wound infections (OR, 4.37; 95% CI, 3.08–6.21; P < 0.001) with no heterogeneity (I2 = 12%) compared to stoma absent in colorectal cancer. The stoma present had significantly higher surgical site wound infections compared to the stoma absent in colorectal cancer. The low number of selected studies in the meta-analysis calls for care when analysing the results. 相似文献

PURPOSE: We used utility assessment to evaluate patient preferences for current urinary and sexual function after radical prostatectomy. MATERIALS AND METHODS: We measured preferences in 209 community volunteers enrolled in a prostate cancer screening study who underwent radical prostatectomy between 1994 and 1998. We compared preferences in 3 outcome groups, namely men bothered by current urinary and sexual functioning, only bothered by current sexual functioning and not bothered by current sexual or urinary functioning. Preferences were assessed via a computer based interview using time trade-off and standard gamble methods. Current functioning was assessed via a standardized questionnaire. RESULTS: Median time trade-off and standard gamble utilities were high at 0.9 across outcome groups, indicating that men were not willing to give up many remaining life years (10% of remaining life expectancy) with current functioning to achieve ideal functioning. However, mean time trade-off and standard gamble scores significantly decreased as the burden increased in men bothered by current sexual and urinary function (0.77 and 0.82), bothered by current sexual function only (0.87 and 0.89) and not bothered by sexual or urinary function (0.92 and 0.96, respectively). CONCLUSIONS: Health related quality of life was generally good in this observational study of patients treated for prostate cancer with radical prostatectomy. In addition, those bothered by urinary and/or sexual function would not be willing to trade much of the remaining life span to achieve perfect functioning. However, the perception of side effects was bothersome enough in some men to warrant appropriate patient counseling regarding the potential risks and benefits. 相似文献
