384 Background: Colonoscopy screening reduces the incidence of, and mortality from, colorectal cancer (CRC) in individuals with HNPCC. The aim of this study was to determine the impact of colonoscopic follow-up in individuals at high risk of HNPCC, in terms of detection of precursor lesions (adenomas) or cancer. Methods: Between 2005-2008, 163 individuals with HNPCC were advised to undergo regular follow-up colonoscopy. Compliance and results of the scans were evaluated annually and were verified with medical documentation. Results: Of the 125 individuals who underwent at least one colonoscopy during the follow-up period of colonoscopy screening, in 33 subjects (26%) at least one colonic adenoma was detected. The median number of adenomas detected per colonoscopy in individuals with polyps was 2. The number of colonoscopies with polyps did not differ between women and men. However, the number of polyps removed by colonoscopy and the total number of polyps removed during the follow-up period was significantly higher in men (p = 0.005, p = 0.05 bilateral, respectively). 5 individuals (4%) were diagnosed with CRC, one of whom had two synchronous tumors. Of these, four individuals had properly followed the screening recommendations with the recommended frequency. In the case where two synchronous tumors were detected, it was the first colonoscopy screening that had been performed on the individual. None had had cancer previously, they were healthy relatives of an index case. All except one belonged to families that fulfilled the Amsterdam criteria I / II. All the tumors were diagnosed at an early stage, except two, which exhibited positive nodes. Conclusions: Colonoscopy screening is effective in diagnosing colorectal adenomas and cancer in individuals with HNPCC. Men with HNPCC have a greater number of colorectal adenomas. Screening allows the detection of colorectal cancer at an early stages. Funded by a young researcher's grant from the Spanish Society of Medical Oncology 2006.

The Impact

This study was conducted to evaluate the significance of preoperative serum sialic acid levels in the diagnosis and prognosis of colorectal cancer (CRC). Total sialic acid (TSA) was determined by the thiobarbituric acid method and normalized to total protein (TP). A postoperative follow-up of CRC patients classified as Dukes’ stages A, B or C was performed and survival analysis was carried out to evaluate the impact of sialic acid levels on tumor recurrence. Our diagnostic studies indicate that TSA/TP is a better marker than either TSA or carcinoembryonic antigen (CEA), especially for the detection of CRC patients at an early stage. At a cutoff of 30.90 nmol/mg of protein, TSA/TP showed a sensitivity of 85% with a specificity of 97% to discriminate CRC patients from healthy donors. In survival analysis, both TSA and TSA/TP were found to be significant prognostic factors for tumor recurrence in CRC. Furthermore, TSA/TP could distinguish patients at high risk of recurrence within Dukes’ stage B and in multivariate analysis it was identified as the best independent prognostic factor. According to our results, preoperative serum TSA/TP content could supply additional information to that provided by Dukes’ stage about the prognosis of CRC patients.

Abstract Purpose To gain more insight into the course of chemotherapy-induced peripheral neuropathy (CIPN) and its impact on health-related quality of life (HRQoL) in a population-based sample of colorectal cancer (CRC) patients up to 2 years after diagnosis. Methods All newly diagnosed CRC patients from four hospitals in the Netherlands were eligible for participation in an ongoing prospective cohort study. Patients (n = 340) completed questions on CIPN (EORTC QLQ-CIPN20) and HRQoL (EORTC QLQ-C30) before initial treatment (baseline) and 1 and 2 years after diagnosis. Results Among chemotherapy-treated patients (n = 105), a high sensory peripheral neuropathy (SPN) level was reported by 57% of patients at 1 year, and 47% at 2-year follow-up, whereas a high motor peripheral neuropathy (MPN) level was reported by 47% and 28%, at years 1 and 2, respectively. Linear mixed model analyses showed that SPN and MPN symptoms significantly increased from baseline to 1-year follow-up and did not return to baseline level after 2 years. Patients with a high SPN or MPN level reported a worse global quality of life and a worse physical, role, emotional, cognitive, and social functioning compared with those with a low SPN or MPN level. Conclusions Future studies should focus on understanding the mechanisms underlying CIPN so targeted interventions can be developed to reduce the impact of CIPN on patient’s lives. Implications for cancer survivors Patients need to be informed of both CIPN and the impact on HRQoL.

AbstractCanAssist Breast (CAB) has thus far been validated on a retrospective cohort of 1123 patients who are mostly Indians. Distant metastasis–free survival (DMFS) of more than 95% was observed with significant separation (P < 0.0001) between low-risk and high-risk groups. In this study, we demonstrate the usefulness of CAB in guiding physicians to assess risk of cancer recurrence and to make informed treatment decisions for patients. Of more than 500 patients who have undergone CAB test, detailed analysis of 455 patients who were treated based on CAB-based risk predictions by more than 140 doctors across India is presented here. Majority of patients tested had node negative, T2, and grade 2 disease. Age and luminal subtypes did not affect the performance of CAB. On comparison with Adjuvant! Online (AOL), CAB categorized twice the number of patients into low risk indicating potential of overtreatment by AOL-based risk categorization. We assessed the impact of CAB testing on treatment decisions for 254 patients and observed that 92% low-risk patients were not given chemotherapy. Overall, we observed that 88% patients were either given or not given chemotherapy based on whether they were stratified as high risk or low risk for distant recurrence respectively. Based on these results, we conclude that CAB has been accepted by physicians to make treatment planning and provides a cost-effective alternative to other similar multigene prognostic tests currently available.

Abstract Background: Aberrant DNA methylation acts epigenetically to skew the gene transcription rate up or down, with causative roles in the etiology of cancers. However research on the role of DNA methylation in driving the progression of cancers is limited. In this study, we have developed a comprehensive computational framework for the stage-differentiated modelling of DNA methylation landscapes in colorectal cancer (CRC), and unravelled significant stagewise signposts of CRC progression. Methods: The methylation β - matrix was derived from the public-domain TCGA data, converted into M-value matrix, annotated with AJCC stages, and analysed for stage-salient genes using multiple approaches involving stage-differentiated linear modelling of methylation patterns and/or expression patterns. Differentially methylated genes (DMGs) were identified using a contrast against controls (adjusted p-value <0.001 and |log fold-change of M-value| >2). These results were filtered using a series of all possible pairwise stage contrasts (p-value <0.05) to obtain stage-salient DMGs. These were then subjected to a consensus analysis, followed by Kaplan–Meier survival analysis to evaluate the impact of methylation patterns of consensus stage-salient biomarkers on disease prognosis.Results: We found significant genome-wide changes in methylation patterns in cancer cases relative to controls agnostic of stage. Our stage-differentiated analysis yielded the following stage-salient genes: one stage-I gene (FBN1), one stage-II gene (FOXG1), one stage-III gene (HCN1) and four stage-IV genes (NELL1, ZNF135, FAM123A, LAMA1). All the biomarkers were hypermethylated, indicating down-regulation and signifying a CpG island Methylator Phenotype (CIMP) manifestation. A significant prognostic signature consisting of FBN1 and FOXG1 survived all the steps of our analysis pipeline, and represents a novel early-stage biomarker. Conclusions: We have designed a workflow for stage-differentiated consensus analysis, and identified stage-salient diagnostic biomarkers and an early-stage prognostic biomarker panel. Our studies further yield a novel CIMP-like signature of potential clinical import underlying CRC progression.

AbstractOur study aims to investigate the impact of miR-224 on cell migration and invasion in colorectal cancer (CRC) as well as its molecular mechanisms. The results showed that miR-224 was significantly upregulated in CRC compared to normal tissues via the TCGA database. Overexpression of miR-224 promoted CRC cell migration and invasion, while inhibition of miR-224 demonstrated the opposite result via transwell assays. In addition, we found that BTRC was a target gene of miR-224 through the miRecords database and dual-luciferase assay, while western blot together with RT-qPCR showed that inhibition of miR-224 led to elevated BTRC expression in protein level but not in mRNA level, and also decreased the expression of β-catenin. In reference to the Human Protein Atlas, BTRC protein expression was higher in normal tissues than in CRC tissues. In conclusion, miR-224 regulates its target BTRC protein expression and its related Wnt/β-catenin pathway. Its impact on cell migration and invasion in CRC cells suggested that miR-224 could be a prospective therapeutic target for early-stage non-metastatic CRC.

ObjectiveCancer survivors’ perceptions of healthcare have been identified as a predictor of quality of life (QoL) outcomes. This study aims to explore colorectal cancer (CRC) survivors’ perceptions of how cancer-related healthcare affects their QoL.MethodsSemistructured interviews were conducted with 22 CRC survivors receiving follow-up care between 1 and 5 years post diagnosis. Interviews were recorded, transcribed and analysed thematically.ResultsFive themes described the impact of healthcare experiences on CRC survivors’ QoL. While cancer survivors spoke positively of their relationships with healthcare professionals, many experienced a range of unmet information and supportive care needs. Participants described a range of positive and negative experiences, as power dynamics and navigation of healthcare systems had implications for their QoL. Where negative healthcare events aligned, survivors’ autonomy, dignity and confidence were undermined, and survivorship issues could be inadequately addressed. To address persistent unmet needs, survivors developed a safety net(work) of supports to bridge the gap of unmet needs in healthcare with varying outcomes.ConclusionsCancer survivors’ experience of follow-up and healthcare can positively or negatively affect their QoL. Preparation for cancer survivorship must be incorporated into the acute phase of diagnosis and treatment and interlinked with clear pathways of survivorship care and accessible supportive care, which support survivors to be equal partners in their healthcare. Understanding cancer survivors’ knowledge, expertise and mastery of their condition is essential to ensure delivery of person-centred supportive care that adequately addresses the survivor’s unmet needs.

Purpose To evaluate in a sample of adults who had been noncompliant with colorectal cancer (CRC) screening whether screening could be enhanced by an automated patient recall system based on identifying high-risk individuals using the ColonFlag test and an electronic medical record database. Methods A total of 79,671 individuals who were determined to be noncompliant with current screening recommendations were identified in the Maccabi Health Services program in Israel. Their cancer risk was determined by ColonFlag using information on age, sex, and CBC results. Doctors of individuals who were flagged as high risk were notified and asked to follow up with their patients. Results The ColonFlag identified 688 men and women who scored in the highest 0.87 percentile. Of these individuals, 254 had colonoscopies performed by Maccabi physicians, and 19 CRCs (7.5%) were found. An additional 15 cancers primarily identified outside of Maccabi were found through code matching. Conclusion The ColonFlag test is a rapid, efficient, and inexpensive test that can be applied to scan electronic medical records to identify individuals at high risk of CRC who would otherwise avoid screening.

Abstract Background Suicide is a major public health issue worldwide. Those who have made a recent suicide attempt are at high risk for dying by suicide in the future, particularly during the period immediately following departure from a hospital emergency department. As such the transition from hospital-based care to the community is an important area of focus in the attempt to reduce suicide rates. There is a need for evaluation studies to test the effectiveness of interventions directed to this stage (termed ‘aftercare’ interventions). Methods A controlled non-randomised two group (intervention vs treatment-as-usual control) design, using an intention-to-treat model, will evaluate the effectiveness of a suicide prevention aftercare intervention providing follow-up after presentations to a hospital emergency department as a result of a suicide attempt or high risk for suicide. The intervention is a community-based service, utilising two meetings with a mental health clinician and follow-up contacts by peer workers via a combination of face-to-face and telephone for four weeks, with the option of extension to 12 weeks. Seventy-five participants of the intervention service will be recruited to the study and compared to 1265 treatment-as-usual controls. The primary hypotheses are that over 12 months, those who participate in the aftercare follow-up intervention are less likely than controls to present to a hospital emergency department for a repeat suicide attempt or because of high risk for suicide, will have fewer re-presentations during this period and will have lower all-cause mortality. As a secondary aim, the impact of the intervention on suicide risk factors for those who participate in the service will be evaluated using pre- and post-intervention repeated measures of depression, anxiety, stress, hopelessness, belongingness, burdensomeness, and psychological distress. Enrolments into the study commenced on 1 November 2017 and are anticipated to cease in November 2019. Discussion The study aims to contribute to the understanding of effective interventions for individuals who have presented to a hospital emergency department as a result of a suicide attempt or at high risk for suicide and provide evidence in relation to interventions that incorporate peer-workers.

Histopathologic Features

The impact on survival of a second primary melanoma (SPM) is unclear. We used our melanoma center's database to examine clinicopathologic risk factors and outcomes of stage 0 to IV cutaneous melanoma in patients with one versus two primaries. Among 12,325 patients with primary melanoma, 969 (7.86%) developed SPM. SPMs were significantly thinner than autologous primary melanomas ( P = 0.01), and 451 SPM patients had better overall and melanoma-specific survival than 451 prognostically matched non-SPM patients ( P < 0.0001 and 0.0001, respectively) at a median follow-up of 142.37 months. Patients with cutaneous melanoma are at high risk for development of SPM, but the development of SPM does not seem to impair survival.
