ABSTRACT
INTRODUCTION: Amidst the rising number of cancer survivors and personnel shortages, optimisation of follow-up strategies is imperative, especially since intensive follow-up does not lead to survival benefits. Understanding patient preferences and identifying the associated patient profiles is crucial. Coping style may be a key determinant in achieving this. Our study aims to evaluate preferences, identify coping styles and their associated factors, and explore the association between coping style and patients' preferences in colorectal cancer (CRC) follow-up. METHODS: In a prospective multicentre implementation study, patients completed the Threatening Medical Situations Inventory (TMSI) to determine their coping style. Simultaneously patients choose their follow-up preferences for the CRC trajectory regarding frequency of tumour marker determination, location of blood sampling, and manner of contact. RESULTS: A total of 188 patients completed the TMSI questionnaire after inclusion. A more intensive follow-up was preferred by 71.5% of patients. Of all patients, 52.0% had a coping style classified as 'blunting' and 34.0% as 'monitoring'. Variables such as a younger age, female gender, higher educational level, and lower ASA scores were associated with having higher monitoring scores. However, there were no significant associations between follow-up preferences and patients' coping styles. CONCLUSION: This study suggests that none of the provided options in a patient-led follow-up are unsuitable for patients who underwent curative surgery for primary CRC, based on coping style determined at baseline. Low-intensity surveillance after curative resection of CRC may, therefore, be suitable for a wide range of patients independent of coping styles.

AIM: Follow-up for colorectal cancer (CRC) necessitates regular monitoring of carcinoembryonic antigen (CEA) at the hospital. Capillary home-based blood collection, including minimally invasive techniques such as lancet sampling or an automated upper arm device (TAP-II), has the potential to replace a significant portion of hospital-based blood sampling, thereby enhancing self-reliance and quality of life. The objectives of this study were to assess the feasibility, reliability and preference for CEA blood collection. METHODS: Baseline venous and capillary (by lancet and TAP-II) blood samples were collected from 102 participants, including 20 CRC patients with elevated CEA levels, 60 CRC patients undergoing postoperative outpatient monitoring and 20 healthy volunteers. The second group performed capillary blood collections at home on two consecutive follow-up appointments and subsequently sent them to the hospital. Satisfaction was assessed via patient reported outcome measures on pain, burden, ease of use and preference. RESULTS: The Pearson's correlation test of all usable samples resulted in a linear coefficient of 0.998 (95% CI 0.997-0.998) for the TAP-II method and 0.997 (95% CI 0.996-0.998) for the lancet method, both compared to venipuncture. Following the initial blood collection, 86% of the participants (n = 102) favoured the TAP-II, rating it as the least painful and burdensome option. After two home-based blood samples, the preference for the TAP-II method persisted, with 64% of the patients endorsing its use. CONCLUSION: This study demonstrated the feasibility of home-based capillary sampling of CEA. The TAP-II blood collection is the most reliable method and is preferred by patients over venipuncture and lancet sampling.

Importance: Unintended tumor-positive resection margins occur frequently during minimally invasive surgery for colorectal liver metastases and potentially negatively influence oncologic outcomes. Objective: To assess whether indocyanine green (ICG)-fluorescence-guided surgery is associated with achieving a higher radical resection rate in minimally invasive colorectal liver metastasis surgery and to assess the accuracy of ICG fluorescence for predicting the resection margin status. Design, Setting, and Participants: The MIMIC (Minimally Invasive, Indocyanine-Guided Metastasectomy in Patients With Colorectal Liver Metastases) trial was designed as a prospective single-arm multicenter cohort study in 8 Dutch liver surgery centers. Patients were scheduled to undergo minimally invasive (laparoscopic or robot-assisted) resections of colorectal liver metastases between September 1, 2018, and June 30, 2021. Exposures: All patients received a single intravenous bolus of 10 mg of ICG 24 hours prior to surgery. During surgery, ICG-fluorescence imaging was used as an adjunct to ultrasonography and regular laparoscopy to guide and assess the resection margin in real time. The ICG-fluorescence imaging was performed during and after liver parenchymal transection to enable real-time assessment of the tumor margin. Absence of ICG fluorescence was favorable both during transection and in the tumor bed directly after resection. Main Outcomes and Measures: The primary outcome measure was the radical (R0) resection rate, defined by the percentage of colorectal liver metastases resected with at least a 1 mm distance between the tumor and resection plane. Secondary outcomes were the accuracy of ICG fluorescence in detecting margin-positive (R1; <1 mm margin) resections and the change in surgical management. Results: In total, 225 patients were enrolled, of whom 201 (116 [57.7%] male; median age, 65 [IQR, 57-72] years) with 316 histologically proven colorectal liver metastases were included in the final analysis. The overall R0 resection rate was 92.4%. Re-resection of ICG-fluorescent tissue in the resection cavity was associated with a 5.0% increase in the R0 percentage (from 87.4% to 92.4%; P < .001). The sensitivity and specificity for real-time resection margin assessment were 60% and 90%, respectively (area under the receiver operating characteristic curve, 0.751; 95% CI, 0.668-0.833), with a positive predictive value of 54% and a negative predictive value of 92%. After training and proctoring of the first procedures, participating centers that were new to the technique had a comparable false-positive rate for predicting R1 resections during the first 10 procedures (odds ratio, 1.36; 95% CI, 0.44-4.24). The ICG-fluorescence imaging was associated with changes in intraoperative surgical management in 56 (27.9%) of the patients. Conclusions and Relevance: In this multicenter prospective cohort study, ICG-fluorescence imaging was associated with an increased rate of tumor margin-negative resection and changes in surgical management in more than one-quarter of the patients. The absence of ICG fluorescence during liver parenchymal transection predicted an R0 resection with 92% accuracy. These results suggest that use of ICG fluorescence may provide real-time feedback of the tumor margin and a higher rate of complete oncologic resection.

PURPOSE: The accessibility of cancer care faces challenges due to the rising prevalence of colorectal cancer (CRC) coupled with a shrinkage of healthcare professionals-known as the double aging phenomenon. To ensure sustainable and patient-centred care, innovative solutions are needed. This study aims to assess the needs of CRC patients regarding their follow-up care. METHODS: This study uses a mixed-method approach divided in three phases. The initial phase involved focus group sessions, followed by semi-structured interviews to identify patients' needs during follow-up. Open analysis was done to define main themes and needs for patients. In the subsequent quantitative phase, a CRC follow-up needs questionnaire was distributed to patients in the follow-up. RESULTS: After two focus groups (n = 14) and interviews (n = 5), this study identified six main themes. Findings underscore the importance of providing assistance in managing both physical and mental challenges associated with cancer. Participants emphasised the need of a designated contact person and an increased focus on addressing psychological distress. Furthermore, patients desire individualised feedback on quality of life questionnaires, and obtaining tailored information. The subsequent questionnaire (n = 96) revealed the priority of different needs, with the highest priority being the need for simplified radiology results. A possible approach to address a part of the diverse needs could be the implementation of a platform; nearly 70% of patients expressed interest in the proposed platform. CONCLUSIONS: CRC patients perceive substantial room for improvement of their follow-up care. Findings can help to develop a platform fulfilling the distinct demands of CRC patients during follow-up.

Circulating tumour DNA (ctDNA) is a potential biomarker that could contribute to more judicious patient selection for personalised treatment. This review and meta-analysis gives an overview of the current knowledge in the literature investigating the value of ctDNA in patients with colorectal liver metastases (CRLM). A systematic search was conducted in electronic databases for studies published prior to the 26th of May 2023. Studies investigating the association between ctDNA and oncological outcomes in patients undergoing curative-intent local therapy for CRLM were included. Meta-analyses were performed to pool hazard ratios (HR) for the recurrence-free survival (RFS) and overall survival (OS). A total of eleven studies were included and nine were eligible for meta-analyses. Patients with detectable ctDNA after surgery experienced a significantly higher chance of recurrence (HR 3.12, 95% CI 2.27-4.28, p < 0.000010) and shorter OS (HR 5.04, 95% CI 2.53-10.04, p < 0.00001) compared to patients without detectable ctDNA. A similar association for recurrence was found in patients with detectable ctDNA after the completion of adjuvant therapy (HR 6.39, 95% CI 2.13-19.17, p < 0.0009). The meta-analyses revealed no association between detectable ctDNA before surgery and the RFS and OS. These meta-analyses demonstrate the strong association between detectable ctDNA after treatment and oncological outcomes in CRLM patients.

INTRODUCTION: Colorectal cancer (CRC) is the third most common type of cancer in the Netherlands. Approximately 90% of patients can be treated with surgery, which is considered potentially curative. Postoperative surveillance during the first 5 years after surgery pursues to detect metastases in an early, asymptomatic and treatable stage. Multiple large randomised controlled trials have failed to show any (cancer-specific) survival benefit of intensive postoperative surveillance compared with a minimalistic approach in patients with CRC. This raises the question whether an (intensive) in-hospital postoperative surveillance strategy is still warranted from both a patient well-being and societal perspective. A more modern, home-based surveillance strategy could be beneficial in terms of patients' quality of life and healthcare costs. METHODS AND ANALYSIS: The multicentre, prospective FUTURE-primary study implements a patient-led home-based surveillance after curative CRC treatment. Here, patients are involved in the choice regarding three fundamental aspects of their postoperative surveillance. First regarding frequency, patients can opt for additional follow-up moments to the minimal requirement as outlined by the current Dutch national guidelines. Second regarding the setting, both in-hospital or predominantly home-based options are available. And third, concerning patient-doctor communication choices ranging from in-person to video chat, and even silent check-ups. The aim of the FUTURE-primary study is to evaluate if such a patient-led home-based follow-up approach is successful in terms of quality of life, satisfaction and anxiety compared with historic data. A successful implementation of the patient-led aspect will be assessed by the degree in which the additional, optional follow-up moments are actually utilised. Secondary objectives are to evaluate quality of life, anxiety, fear of cancer recurrence and cost-effectiveness. ETHICS AND DISSEMINATION: Ethical approval was given by the Medical Ethics Review Committee of Erasmus Medical Centre, The Netherlands (2021-0499). Results will be presented in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05656326.

AIM: Follow-up after colorectal cancer requires frequent surveillance of the tumour marker carcinoembryonic antigen (CEA). Home-based blood sampling could be beneficial in terms of patients' well-being and societal cost-effectiveness. Blood sampling by venepuncture is unsuitable for home-based sampling. The aim of this feasibility study is to evaluate the long-term whole-blood stability of CEA. METHOD: In this prospective feasibility study capillary blood withdrawal was collected in a Hem-Col® microtube containing a patented stabilization buffer using an internal lithium standard to correct for dilution. Long-term whole-blood stability was considered adequate if the relative bias in CEA concentration between delayed analysis of capillary samples and directly processed venepuncture is within the total error margin of CEA. RESULTS: Twenty two colorectal cancer patients were included to determine the stability of CEA in capillary sampling compared with directly processed (i.e. within 2 h) venepuncture sampling. The median time between venous sampling and CEA analysis and capillary sampling and CEA analysis was 2 h (interquartile range 1-4 h) and 76 h (interquartile range 74-95 h), respectively. A Bland-Altman difference plot excluding outliers showed an overall relative bias of -1.23%. The two capillary samples in our outlier analysis also showed the highest lithium concentrations. CONCLUSION: Home-based capillary sampling with the use of the Hem-Col® buffer is a feasible method for CEA determination when analysed within 4 days after blood withdrawal, allowing monitoring for colorectal cancer patients from home. High lithium concentrations due to insufficient filling of the Hem-Col® tube suggest less reliable CEA measurements.

BACKGROUND: Previous trials found that more intensive postoperative surveillance schedules did not improve survival. Oncological follow-up also provides an opportunity to address psychological issues (for example anxiety, depression, and fear of recurrence). This systematic review assessed the impact of a less intensive surveillance strategy on health-related quality of life (HRQoL), emotional well-being, and patient satisfaction. METHODS: A systematic search was conducted in PubMed/MEDLINE, Embase, Web of Science, Cochrane database, PsycINFO, and Google Scholar to identify studies comparing different follow-up strategies after oncological surgery and their effect on HRQoL and patient satisfaction, published before 4 May 2022. A meta-analysis was conducted on the most relevant European Organisation for Research and Treatment of Cancer QLQ-C30 and Hospital Anxiety and Depression Scale subscales. RESULTS: Thirty-five studies were identified, focusing on melanoma (4), colorectal (10), breast (7), prostate (4), upper gastrointestinal (4), gynaecological (3), lung (2), and head and neck (1) cancers. Twenty-two studies were considered to have a low risk of bias, of which 14 showed no significant difference in HRQoL between follow-up approaches. Five studies with a low risk of bias showed improved HRQoL or emotional well-being with a less intensive follow-up approach and three with an intensive approach. Meta-analysis of HRQoL outcomes revealed no negative effects for patients receiving less intensive follow-up. CONCLUSION: Low-intensity follow-up does not diminish HRQoL, emotional well-being, or patient satisfaction.

Background: Circulating tumour DNA (ctDNA) has been established as a promising (prognostic) biomarker with the potential to personalise treatment in cancer patients. The objective of this systematic review is to provide an overview of the current literature and the future perspectives of ctDNA in non-metastatic rectal cancer. Methods: A comprehensive search for studies published prior to the 4th of October 2022 was conducted in Embase, Medline, Cochrane, Google scholar, and Web of Science. Only peer-reviewed original articles and ongoing clinical trials investigating the association between ctDNA and oncological outcomes in non-metastatic rectal cancer patients were included. Meta-analyses were performed to pool hazard ratios (HR) for recurrence-free survival (RFS). Results: A total of 291 unique records were screened, of which 261 were original publications and 30 ongoing trials. Nineteen original publications were reviewed and discussed, of which seven provided sufficient data for meta-analyses on the association between the presence of post-treatment ctDNA and RFS. Results of the meta-analyses demonstrated that ctDNA analysis can be used to stratify patients into very high and low risk groups for recurrence, especially when detected after neoadjuvant treatment (HR for RFS: 9.3 [4.6 - 18.8]) and after surgery (HR for RFS: 15.5 [8.2 - 29.3]). Studies investigated different types of assays and used various techniques for the detection and quantification of ctDNA. Conclusions: This literature overview and meta-analyses provide evidence for the strong association between ctDNA and recurrent disease. Future research should focus on the feasibility of ctDNA-guided treatment and follow-up strategies in rectal cancer. A blueprint for agreed-upon timing, preprocessing, and assay techniques is needed to empower adaptation of ctDNA into daily practice.
