[Post-Cancer Treatment-Related Symptom Distress and Fear of Cancer Recurrence in Colorectal Cancer Survivors].

BACKGROUND: Colorectal cancer (CRC) is a primary cause of cancer-related mortality, and, after treatment, cancer survivors often worry that disease recurrence may worsen their health. Nevertheless, limited research on fear of cancer recurrence (FCR) and treatment-related symptoms has been conducted on survivors of CRC. PURPOSE: This study was designed to explore (1) symptom distress severity and post-treatment FCR in CRC survivors and (2) the predictors of FCR. METHODS: A cross-sectional correlational research design and convenience sampling approach were used to recruit patients at the colorectal surgery outpatient department of a medical center in central Taiwan. Basic demographic data, the Symptom Distress Scale - Chinese Modified Form, and Fear of Progression Questionnaire - Short Form were used as monitoring tools. Pearson's product-moment correlation analysis, independent t-tests, one-way ANOVA, and stepwise linear regression analysis were used for statistical analysis. RESULTS: One hundred fourteen survivors of CRC with an average age of 63.44 were enrolled as participants. The top five symptoms of distress were numbness, bowel patterns, fatigue, insomnia, and dry mouth, and the average FCR score was 18.09. Gender, educational level, monthly disposable income, and symptom distress were identified as significant predictors of FCR, with an overall explanatory power of 41.4%. CONCLUSIONS: Level of post-treatment FCR in survivors of CRC is influenced by symptom distress severity. Early intervention by healthcare providers to control or alleviate physical symptoms can help prevent the emergence of negative emotions and improve quality of life in this patient group.

The role of trust, vaccine information exposure, and Health Belief Model variables in COVID-19 vaccination intentions: Evidence from an HBCU sample.

African Americans have been disproportionately affected by COVID-19 and COVID-19 vaccines were initially met with hesitancy from the African American community. This study identified predictors of COVID-19 vaccination intentions among students attending a Historically Black College and University (HBCU) when COVID-19 vaccines first became available. Unvaccinated students (N = 224) completed a survey. Path analysis modeled relationships among exogenous variables (trust, exposure to pro- and anti-vaccine information), proposed mediators (Health Belief Model variables), and COVID-19 vaccination intentions. Students reported low trust in government officials, medical professionals, and the vaccine development process. Direct predictors of vaccination intentions included trust, perceived benefits, and perceived barriers. Students with lower trust reported lower benefits, increased concerns about side effects, and were more likely to view COVID-19 vaccination as low priority, and these factors in turn predicted intentions. Findings highlight the urgent need for theory-driven, culturally sensitive, age-relevant messaging to reduce vaccine hesitancy among Black young adults.

Third- and First-Person Effects of COVID News in HBCU Students' Risk Perception and Behavioral Intention: Social Desirability, Social Distance, and Social Identity.

With COVID-19's unprecedented impact and ongoing debates on prosocial social distancing and antisocial beach crowd gathering, this study examined the roles of social desirability, social distance marked by race, and social identity in the third-person effect (TPE) of COVID-related news concerning risk perception among Historically Black College and University (HBCU) students. The findings confirmed third- and first-person effects with the perceived influence of antisocial (beach partying) news greater for others than themselves, whereas the self was perceived to be more responsive to the influence of prosocial (social distancing) news. A symmetric interaction between social desirability and social identity indicated that the racial out-group, non-HBCU students in Florida were perceived as more affected by antisocial beach party news, whereas the in-group HBCU peers were perceived as more influenced by desirable social distancing warning news and COVID news in general. The first-person perception and shrunk self-other gap in COVID news influence on HBCU students" concerns may be associated with perceived personal vulnerability and responsibility as well as a political reflection on the government's handling of COVID. While they presumed favorable media influence on self and the in-group to preserve collective self-esteem, they made realistic threat judgments from perceiving undesirable media influence on their in-group peers' risky behavior tendency and intended to take preventive actions (staying home) to avoid the health risk. Further, it was the first-person perceptual gap between themselves and the out-group, non-HBCU students that influenced them to heed social distancing warnings.

Survival benefit of metastasectomy in first-line cetuximab therapy in patients with RAS wild-type metastatic colorectal cancer: a nationwide registry.

This multicenter study aimed to explore the survival benefit of metastasectomy by first-line cetuximab-based chemotherapy in real-world patients with RAS wild-type metastatic colorectal cancer (mCRC). The primary endpoints were overall survival (OS) and progression-free survival (PFS). The secondary endpoints included objective response rate (ORR), disease control rate (DCR), and metastasectomy rate. The exploratory endpoint was the optimal treatment cycle for better OS and PFS. Receiver operating characteristic curve with the area under curve (AUC) was used to identify the optimal cut-off cycle for survival outcomes. A total of 758 mCRC patients were enrolled in this study, with a median OS of 35.1 months, median PFS of 14.6 months, and metastasectomy rate of 21.4%. Left-sided mCRC had a significantly higher DCR (88.9% vs. 73.1%, P<0.001) and better OS (36.4 vs. 19.6 months, P<0.001). There were no significant differences in PFS and metastasectomy rate between left-sided and right-sided mCRC. However, mCRC patients who underwent metastasectomy over the course of treatment had better OS (54.9 vs. 28.6 months, P<0.001) and PFS (21.0 vs. 13.1 months, P<0.001) than those who did not. Notably, right-sided mCRC who benefited from first-line cetuximab-based chemotherapy to underwent metastasectomy also had favorable outcomes, on a par with left-sided mCRC. The optimal treatment cycle was 14 cycles (AUC: 0.779, P<0.001). Patients who received ≥14 cycles had higher metastasectomy rates (27.5% vs. 13.5%, P<0.001), favorable OS (42.6 vs. 23.4 months, P<0.001) and PFS (18.1 vs. 8.6 months, P<0.001), and, importantly, had comparable adverse events compared with patients who received <14 cycles of treatment. Patients who underwent metastasectomy after or during first-line cetuximab therapy have an improved OS in both left-sided and right-sided mCRC. Furthermore, patients receive ≥14 cycles of treatment whenever possible to achieve a higher likelihood of metastasectomy was associated with favorable survival outcomes.

Coping, COVID knowledge, communication, and HBCU student's emotional well-being: Mediating role of perceived control and social connectedness.

The pandemic has disproportionately affected African American college students, who have experienced significant work-related, academic, financial, and socio-emotional challenges due to COVID-19. The purpose of the study is to investigate how African American students cope with the severe impact of COVID-19 on their emotional well-being leveraging the benefits of self-care coping measures, COVID-19 knowledge, and communication with others to enhance perceived control and social connectedness. A structural equation modeling and a path analysis of 254 responses from a Historically Black College and University showed that emotional well-being was positively predicted by self-care coping strategies, feelings of being in control in life, and social connectedness. In addition, respondents who adopted mind-body balance coping strategies, those who are knowledgeable about COVID-19, and those in more constant communication with others attained a strong sense of being in control, and in turn the empowerment increased their emotional well-being.

Comparison Between Same-Day and Split-Dose Preparations with Sodium Picosulfate/Magnesium Citrate: A Randomized Noninferiority Study.

BACKGROUND: Sodium picosulfate/magnesium citrate (SPMC) is a small-volume bowel cleansing agent with similar efficacy to and better tolerability than polyethylene glycol. However, we found no data on which SPMC preparation (same-day vs. split-dose) provides better bowel cleansing efficacy for afternoon colonoscopy. AIMS: To compare bowel cleansing efficacy of different timing of the regimen. METHODS: This randomized, single-center, endoscopist-blinded, noninferior study compared same-day and split-dose SPMC preparations for afternoon colonoscopy in 101 and 96 patients, respectively. We also included a prospective observation group of 100 patients receiving morning colonoscopy to compare bowel preparation between morning and afternoon colonoscopies. Bowel cleansing efficacy was then evaluated by the Aronchick Scale, Ottawa Bowel Preparation Scale (OBPS), Boston Bowel Preparation Scale (BBPS), and the Bubble Scale. RESULTS: Same-day and split-dose preparations were similar in efficacy in all four scales. In the Aronchick Scale, the success rate (excellent and good cleanliness) was higher in same-day preparation than in split-dose preparation (100% vs. 92.8%). The same-day preparation also obtained a better OBPS score (1.4 vs. 2.1), but BBPS showed no difference between such groups (7.7 vs. 7.4). CONCLUSION: Same-day preparation with SPMC is not inferior to split-dose preparation for afternoon colonoscopy.

Determination of the UGT1A1 polymorphism as guidance for irinotecan dose escalation in metastatic colorectal cancer treated with first-line bevacizumab and FOLFIRI (PURE FIST).

AIM: Uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) polymorphism plays a crucial role in the increased susceptibility of patients to irinotecan and its toxicity. This study is a multicenter, randomised clinical trial comparing the clinical outcomes and adverse events (AEs) in metastatic colorectal cancer (mCRC) patients treated with bevacizumab plus FOLFIRI with or without UGT1A1 genotyping and irinotecan dose escalation as the first-line therapy. METHODS: The control group received conventional biweekly FOLFIRI plus bevacizumab without UGT1A1 genotyping, whereas the study group received the same regimen with irinotecan dose escalation based on UGT1A1 genotyping. The primary end-point was progression-free survival (PFS), and secondary end-points were overall response rate (ORR), disease control rate (DCR), overall survival (OS), AEs and metastasectomy rate. RESULTS: Over a median follow-up of 26.0 months (IQR, 17.0-35.0 months), study group (n = 107) was superior to the control group (n = 106) in PFS, OS, ORR, DCR, and metastasectomy rate (all P < 0.05). Furthermore, there were no significant differences in AEs ≥ grade III between the two groups, even with the 1.36-fold increase in the relative dose intensity of irinotecan in the study group. Dose escalation of irinotecan, an independent factor of ORR (P < 0.001) and DCR (P = 0.006), improved PFS in mCRC patients with wild-type and mutant KRAS (P = 0.007 and P = 0.019, respectively). CONCLUSION: The current study revealed that mCRC patients, regardless of KRAS gene status, with UGT1A1 genotyping can tolerate escalated doses of irinotecan and potentially achieve a more favourable clinical outcome without significantly increased toxicities. CLINICAL TRIAL REGISTRATION: NCT02256800.

Predictive values of stool-based tests for mucosal healing among Taiwanese patients with ulcerative colitis: a retrospective cohort analysis.

BACKGROUND/PURPOSE: Over the past two decades, ulcerative colitis (UC) has emerged in the Asia Pacific area, and its treatment goal has shifted from symptom relief to endoscopic remission. Endoscopy is the gold standard for the assessment of mucosal healing; however, it is an invasive method. Fecal calprotectin (FC) is a non-invasive stool-based inflammatory marker which has been used to monitor mucosal healing status, but it is expensive. By contrast, the immune fecal occult blood test (iFOBT) is a widely utilized stool-based screening tool for colorectal cancer. In this study, we compared the predictive values of iFOBT and FC for mucosal healing in Taiwanese patients with UC. METHODS: A total of 50 patients with UC identified via the electronic clinical database of Changhua Christian Hospital, Taiwan, were retrospectively enrolled from January 2018 to July 2019. Results of iFOBT, FC level, and blood tests as well as Mayo scores were reviewed and analyzed. Colonic mucosa was evaluated using the endoscopic Mayo subscore. RESULTS: The average age of the patients was 46 years, and 62% of the patients were men. Disease distribution was as follows: E1 (26%), E2 (40%), and E3 (34%). Complete mucosal healing (Mayo score = 0) was observed in 30% of patients. Endoscopic mucosal healing with a Mayo score of 0 or 1 was observed in 62% of the patients. Results of FC and iFOBT were compared among patients with and without mucosal healing. Predictive cutoff values were analyzed using receiver operating characteristics curves. iFOBT and FC had similar area under the curve for both complete mucosal healing (0.813 vs. 0.769, respectively, p = 0.5581) and endoscopic mucosal healing (0.906 vs. 0.812, respectively, p = 0.1207). CONCLUSION: In daily clinical practice, FC and iFOBT do not differ in terms of predictive values for mucosal healing among Taiwanese patients with UC.

Methylation of the Tumor Suppressor Genes HIC1 and RassF1A Clusters Independently From the Methylation of Polycomb Target Genes in Colon Cancer.

BACKGROUND: Methylation changes within tumor suppressor (TS) genes or polycomb group target (PcG) genes alter cell fates. Chromatin associated with PcG targets is bivalent in stem cells, while TS genes are not normally bivalent. PcG target methylation changes have been identified in tumor stem cells, and abnormal methylation is found in TS genes in cancers. If the epigenetic states of genes influence DNA methylation, then methylation of PcG targets and TS genes may evolve differently during cancer development. More importantly, methylation changes may be part of a sequence in tumorigenesis. METHODS: Chromatin and methylation states of 4 PcG targets and 2 TS genes were determined in colon cancer cells. The methylation states were also detected in 100 pairs of colon cancer samples. Principle component analysis (PCA) was used to reveal whether TS methylation or PcG methylation was the main methylation change associated with colon cancers. RESULTS: Chromatin and methylation states differ in colon cancer cell lines. The methylation states within PcG targets clustered independently from the methylation states in TS genes, a finding we previously reported in liver cancers. PCA in colon cancers revealed the strongest association with methylation changes in 2 TS genes, HIC1 and RassF1A. Loss of HIC1 methylation correlated with decreased tumor migration. CONCLUSIONS: PcG and TS methylation states cluster independently from each other. The deduced principle component correlated better with TS methylation than PcG methylation in colon cancer. Abnormal methylation changes may represent a sequential biomarker profile to identify developing colon cancer.
