Using a modified Delphi procedure to select a PRO-CTCAE-based subset for patient-reported symptomatic toxicity monitoring in rectal cancer patients.

PURPOSE: Standardized patient-reported outcomes (PRO) monitoring during and after rectal cancer treatment provides insight into treatment-related toxicities patients experience and improves health-related quality-of-life as well as overall survival. We aimed to select a subset of the PRO version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) for standardized monitoring of treatment-related symptomatic toxicities in rectal cancer. METHODS: We used a mixed methods approach including a literature review, and semi-structured interviews with health care providers (HCPs) involved in rectal cancer care and rectal cancer patients. Results from literature and interviews were summarized and used in a modified Delphi procedure to select a PRO-CTCAE subset specific for rectal cancer. RESULTS: Twenty-six PRO-CTCAE symptomatic toxicities were identified from literature. Fifteen HCPs from multiple disciplines (medical, radiation and surgical oncology), and a heterogeneous group of fifteen rectal cancer patients treated with chemotherapy and/or radiotherapy and/or surgery, participated in semi-structured interviews. Ten HCPs (67%) and nine patients (90%) participated in the first Delphi round. The final selected PRO-CTCAE core-subset contained 16 symptomatic toxicities: 'diarrhea', 'fecal incontinence', 'constipation','bloating of the abdomen', 'pain in the abdomen', 'vomiting', 'decreased libido', 'pain during vaginal sex', 'ability to achieve and maintain erection', 'fatigue', 'anxiety', 'feeling that nothing could cheer you up', 'urinary incontinence', 'painful urination', 'general pain', and 'hand-foot syndrome'. CONCLUSION: Based on a comprehensive mixed methods study, a PRO-CTCAE subset for standardized treatment-related symptomatic toxicity monitoring in rectal cancer was identified. Assessment of the effectiveness and compliance of symptomatic toxicity monitoring using this subset is recommended.

Age-specific impact of comorbidity on postoperative outcomes in older patients with colorectal cancer.

INTRODUCTION: Age and comorbidity are considered the strongest predictors for adverse events after colorectal cancer (CRC) surgery. We aimed to study the interaction of age and comorbidity and to gain better insight in options to improve care for the growing group of older patients. MATERIALS AND METHODS: We included all patients ≥70 years undergoing elective surgery for non-metastatic CRC between 2011 and 2019 in the Netherlands. Baseline characteristics, surgical and non-surgical complications, readmission, and short-term mortality were collected from the Dutch Colorectal Audit (DCRA). The cohort was stratified by 70-79, 80-89, and ≥ 90 years. Comorbidity prevalence and postoperative outcomes were determined per age group. We analyzed the interaction (age-group*comorbidity) with all outcomes using multivariate logistic regression analysis. Age-stratified analysis was indicated if the interaction was significant. RESULTS: We included 25,727 patients of 70-79 years, 12,198 patients of 80-89 years, and 713 of ≥90 years. Non-surgical complications and mortality increased with older age, while surgical complications significantly decreased. However, the association of a Charlson Comorbidity Index (CCI) score ≥ 3, cardiovascular, and cardiopulmonary disease with adverse postoperative outcome decreased with older age. For example, the odds ratio (OR) of a CCI score ≥ 3 for non-surgical complications was 1.79 (confidence interval [CI] 95% 1.66-1.94), 1.50 (CI 95% 1.36-1.65), and 1.21 (CI 95% 0.80-1.81) for, respectively, 70-79, 80-89, and ≥ 90 years. DISCUSSION: The rate of non-surgical complications after CRC surgery increased with older age, although older age itself became less associated with comorbidity. Perhaps risk assessment in the oldest patients should shift towards other predictors, such as frailty.

N3 Disease in Esophageal Cancer: Results from a Nationwide Registry.

BACKGROUND: Patients with extensive lymph node metastases have a poor prognosis. Clinical staging of lymph node metastases poses significant challenges given the limited sensitivity and specificity of imaging techniques. The aim of this study was to investigate the overall survival (OS) of patients with N3 disease in a real-world Dutch population and the added value of surgery in these patients. METHODS: Patients with cN3M0 esophageal or gastroesophageal cancer were identified from the Netherlands Cancer Registry (2012-2019). Treatment consisted of neoadjuvant chemo(radio)therapy followed by resection or chemo(radio)therapy, radiotherapy, or esophagectomy alone. OS was calculated using the Kaplan-Meier method. RESULTS: Some 21,566 patients were diagnosed with esophageal cancer of whom 359 (1.7%) had cN3M0 disease. Median OS of these patients was 12.5 months (95% CI: 10.7-14.3). Median OS following chemoradiotherapy alone and neoadjuvant therapy plus surgery was 13.3 months (95% CI: 10.7-15.9) and 23.7 months (95% CI: 18.3-29.2), respectively. Of all patients who underwent esophagectomy, 391 (2.8%) had (y)pN3 disease, and median OS was 16.1 months (95% CI: 14.8-17.4). Twenty-one patients (5.4%) were correctly classified as cN3, and 3-year OS was 21%. CONCLUSION(S): Clinical staging appears to be difficult, apparently in patients with N3 esophageal cancer. Surgery seems to be of benefit to these patients. More research is required to address the ongoing challenges in clinical staging and the best neoadjuvant therapy.

Interval Metastases After Neoadjuvant Chemoradiotherapy for Patients with Locally Advanced Esophageal Cancer: A Multicenter Observational Cohort Study.

BACKGROUND: Despite trimodality treatment, 10% to 20% of patients with esophageal cancer experience interval metastases after surgery. Restaging may identify patients who should not proceed to surgery, as well as a subgroup with limited metastases for whom long-term disease-control can be obtained. This study aimed to determine the proportion of patients with interval metastases after neoadjuvant chemoradiotherapy (nCRT) and to evaluate treatment and survival. METHODS: Patients who had cT2-4aN0-3M0 esophageal cancer treated with nCRT were identified from a trial database. Metastases detected up to 14 weeks after nCRT on 18F-FDG-PET/CT or during surgery were categorized as oligometastases (≤3 lesions located in one single organ or one extra-regional lymph node station) or as non-oligometastases. The primary outcome was the proportion of patients with metastases after nCRT. The secondary outcomes were overall survival (OS) and the site and treatment of metastases. RESULTS: Between 2013 and 2021, 973 patients received nCRT, and 10.3% had interval metastases. Of 100 patients, 30 (30%) had oligometastases, located mostly in non-regional lymph nodes (33.3%) or bones (26.7%). The median OS of this group was 13.8 months (95% confidence interval [CI] 9.2-27.1 months). Of 30 patients, 12 (40%) with oligometastases underwent potentially curative treatment, with a median OS of 22.8 months (95% CI 10.4-NA). The patients with non-oligometastases underwent mostly systemic therapy or BSC and had a median OS of 9 months (95% CI 7.4-10.9 months). CONCLUSIONS: Interval metastases were detected in about 10% of patients after nCRT, underscoring the importance of re-staging with 18F-FDG-PET/CT for those who proceed to surgery. A favorable survival might be accomplished for a subgroup of patients with oligometastases.

The Effect of (Chemo)Radiotherapy on Enlarged Lateral Lymph Nodes in Patients With Locally Advanced Rectal Cancer.

BACKGROUND: Standard of care for most patients with locally advanced rectal cancer in The Netherlands consists of neoadjuvant chemoradiotherapy (nCRT) followed by resection. Enlarged lateral lymph nodes (LLNs), especially in the iliac compartment, appears to be associated with an increased risk of local recurrence. Little is known about the risk of local recurrence after nCRT. MATERIALS AND METHODS: This study included patients with locally advanced rectal cancer and enlarged LLNs on pretreatment MRI-scan located in the internal iliac, obturator, external iliac, or common iliac compartment. Patients were treated with nCRT and response to therapy was evaluated with MRI-scan. The primary endpoint was local lateral recurrence after nCRT. Secondary endpoints included overall survival and postoperative complications. RESULTS: Out of 260 patients treated for rectal cancer, a total of 46 patients with enlarged LLNs (18% of all patients) were included between 2012 and 2019 in 2 Dutch hospitals. No patients had lateral lymph node recurrence (LLNR) after nCRT. Only 1 patient had local recurrence of rectal cancer after radical resection during a median follow up of 3 years. Disseminated disease was seen in 12 patients and 9 patients died during follow-up, which result in an overall survival rate of 80.4%. Postoperative complications were seen in 41% of patients. There was no 90-days postoperative mortality. CONCLUSION: Enlarged LLNs are rare after nCRT and no LLNR was found after nCRT in our study population. This could suggest that nCRT only with or without an extra radiotherapeutic boost on enlarged LLNs already reduces the risk of LLNR.

Long-term restoration of bowel continuity after rectal cancer resection and the influence of surgical technique: A nationwide cross-sectional study.

AIM: Literature on nationwide long-term permanent stoma rates after rectal cancer resection in the minimally invasive era is scarce. The aim of this population-based study was to provide more insight into the permanent stoma rate with interhospital variability (IHV) depending on surgical technique, with pelvic sepsis, unplanned reinterventions and readmissions as secondary outcomes. METHOD: Patients who underwent open or minimally invasive resection of rectal cancer (lower border below the sigmoid take-off) in 67 Dutch centres in 2016 were included in this cross-sectional cohort study. RESULTS: Among 2530 patients, 1470 underwent a restorative resection (58%), 356 a Hartmann's procedure (14%, IHV 0%-42%) and 704 an abdominoperineal resection (28%, IHV 3%-60%). Median follow-up was 51 months. The overall permanent stoma rate at last follow-up was 50% (IHV 13%-79%) and the unintentional permanent stoma rate, permanent stoma after a restorative procedure or an unplanned Hartmann's procedure, was 11% (IHV 0%-29%). A total of 2165 patients (86%) underwent a minimally invasive resection: 1760 conventional (81%), 170 transanal (8%) and 235 robot-assisted (11%). An anastomosis was created in 59%, 80% and 66%, with corresponding unintentional permanent stoma rates of 12%, 24% and 14% (p = 0.001), respectively. When corrected for age, American Society of Anesthesiologists classification, cTNM, distance to the anorectal junction and neoadjuvant (chemo)radiotherapy, the minimally invasive technique was not associated with an unintended permanent stoma (p = 0.071) after a restorative procedure. CONCLUSION: A remarkable IHV in the permanent stoma rate after rectal cancer resection was found. No beneficial influence of transanal or robot-assisted laparoscopy on the unintentional permanent stoma rate was found, although this might be caused by the surgical learning curve. A reduction in IHV and improving preoperative counselling for decision-making for restorative procedures are required.

Nationwide Association of Surgical Performance of Minimally Invasive Esophagectomy With Patient Outcomes.

Importance: Suboptimal surgical performance is hypothesized to be associated with less favorable patient outcomes in minimally invasive esophagectomy (MIE). Establishing this association may lead to programs that promote better surgical performance of MIE and improve patient outcomes. Objective: To investigate associations between surgical performance and postoperative outcomes after MIE. Design, Setting, and Participants: In this nationwide cohort study of 15 Dutch hospitals that perform more than 20 MIEs per year, 7 masked expert MIE surgeons assessed surgical performance using videos and a previously developed and validated competency assessment tool (CAT). Each hospital submitted 2 representative videos of MIEs performed between November 4, 2021, and September 13, 2022. Patients registered in the Dutch Upper Gastrointestinal Cancer Audit between January 1, 2020, and December 31, 2021, were included to examine patient outcomes. Exposure: Hospitals were divided into quartiles based on their MIE-CAT performance score. Outcomes were compared between highest (top 25%) and lowest (bottom 25%) performing quartiles. Transthoracic MIE with gastric tube reconstruction. Main Outcome and Measure: The primary outcome was severe postoperative complications (Clavien-Dindo ≥3) within 30 days after surgery. Multilevel logistic regression, with clustering of patients within hospitals, was used to analyze associations between performance and outcomes. Results: In total, 30 videos and 970 patients (mean [SD] age, 66.6 [9.1] years; 719 men [74.1%]) were included. The mean (SD) MIE-CAT score was 113.6 (5.5) in the highest performance quartile vs 94.1 (5.9) in the lowest. Severe postoperative complications occurred in 18.7% (41 of 219) of patients in the highest performance quartile vs 39.2% (40 of 102) in the lowest (risk ratio [RR], 0.50; 95% CI, 0.24-0.99). The highest vs the lowest performance quartile showed lower rates of conversions (1.8% vs 8.9%; RR, 0.21; 95% CI, 0.21-0.21), intraoperative complications (2.7% vs 7.8%; RR, 0.21; 95% CI, 0.04-0.94), and overall postoperative complications (46.1% vs 65.7%; RR, 0.54; 95% CI, 0.24-0.96). The R0 resection rate (96.8% vs 94.2%; RR, 1.03; 95% CI, 0.97-1.05) and lymph node yield (mean [SD], 38.9 [14.7] vs 26.2 [9.0]; RR, 3.20; 95% CI, 0.27-3.21) increased with oncologic-specific performance (eg, hiatus dissection, lymph node dissection). In addition, a high anastomotic phase score was associated with a lower anastomotic leakage rate (4.6% vs 17.7%; RR, 0.14; 95% CI, 0.06-0.31). Conclusions and Relevance: These findings suggest that better surgical performance is associated with fewer perioperative complications for patients with esophageal cancer on a national level. If surgical performance of MIE can be improved with MIE-CAT implementation, substantially better patient outcomes may be achievable.

The effect of prehabilitation on long-term survival and hospital admissions in older patients undergoing elective colorectal cancer surgery.

INTRODUCTION: There is a growing body of evidence for a beneficial effect of prehabilitation on short-term outcomes after colorectal cancer (CRC) surgery in older patients. However, long-term effects on survival or hospital admissions have not been investigated. This study reports these long-term outcomes from a previously published observational cohort study. METHODS: We compared patients ≥75 years who received elective CRC surgery in Reinier de Graaf Hospital before (2010-2013: standard care) and after implementation of a multimodal prehabilitation program (2014-2015; prehabilitation). With a six-year follow-up period, we analyzed survival using the Kaplan-Meier method and the occurrence of one or more hospital admissions using logistic regression analyses. RESULTS: Overall, 137 patients were included in the standard care group and 86 patients in the prehabilitation group. There were no differences in patients, tumor and treatment characteristics. After six years, 51.1% in the standard care group and 59.3% in the prehabilitation group (p = 0.167) were still alive. When corrected for confounders in the prehabilitation group less patients had one or more hospital admissions during follow-up (odds ratio (OR) 0.43 (95% CI 0.24-0.77). CONCLUSIONS: Unfortunately these limited historical cohorts did not allow for strong conclusions concerning long-time survival. However, after prehabilitation less patients had hospital admissions during follow up. Hopefully, this first study into the long-term effects of multimodal prehabilitation will trigger more future research.

The Assessment of Burden of ColoRectal Cancer (ABCRC)-tool; a validity and reliability study.

INTRODUCTION: Follow-up care after treatment for colorectal cancer (CRC) is increasingly focused on health-related quality of life (HRQoL) and functional outcomes. The Assessment of Burden of ColoRectal Cancer (ABCRC)-tool is developed to measure these outcomes and support patient-oriented care. The tool comprises items assessing burden of disease and lifestyle parameters. It consists of a generic module combined with one of the three CRC specific modules. The objective of this study is to assess the construct validity and reliability of the items of the ABCRC-tool. METHODS: Patients who were receiving follow-up care after surgical CRC treatment were invited to complete the ABCRC-tool together with other validated patient-reported outcome measures (PROMs). Construct validity was assessed by testing expected correlations between items of the ABCRC-tool and domains of other PROMs and by examining predefined hypotheses regarding differences in subgroups of patients. Patients completed the ABCRC-tool twice, with 8 days apart, to evaluate its reliability. RESULTS: In total, 177 patients participated (64% male) with a mean age of 67 years (range 33-88). The colon, rectum and stoma module were completed by subsequently 89, 53 and 35 patients. Most items correlated as expected with anticipated domains of the EORTC QLQ-C30 or EORTC QLQ-CR29 (all p-values <0.05). Furthermore, the ABCRC-tool could discriminate between subgroups of patients. The intraclass correlation coefficient (ICC) was good (>0.70) for most items, indicating good reliability. CONCLUSION: The ABCRC-tool is a valid and reliable instrument that is ready for use in a clinical setting to support personalized follow-up care after CRC treatment.

Prognostic value of Mandard score and nodal status for recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma.

BACKGROUND: This study evaluated the association of pathological tumour response (tumour regression grade, TRG) and a novel scoring system, combining both TRG and nodal status (TRG-ypN score; TRG1-ypN0, TRG>1-ypN0, TRG1-ypN+ and TRG>1-ypN+), with recurrence patterns and survival after multimodal treatment of oesophageal adenocarcinoma. METHODS: This Dutch nationwide cohort study included patients treated with neoadjuvant chemoradiotherapy followed by oesophagectomy for distal oesophageal or gastro-oesophageal junctional adenocarcinoma between 2007 and 2016. The primary endpoint was the association of Mandard score and TRG-ypN score with recurrence patterns (rate, location, and time to recurrence). The secondary endpoint was overall survival. RESULTS: Among 2746 inclusions, recurrence rates increased with higher Mandard scores (TRG1 30.6%, TRG2 44.9%, TRG3 52.9%, TRG4 61.4%, TRG5 58.2%; P < 0.001). Among patients with recurrent disease, the distribution (locoregional versus distant) was the same for the different TRG groups. Patients with TRG1 developed more brain recurrences (17.7 versus 9.8%; P = 0.001) and had a longer mean overall survival (44 versus 35 months; P < 0.001) than those with TRG>1. The TRG>1-ypN+ group had the highest recurrence rate (64.9%) and worst overall survival (mean 27 months). Compared with the TRG>1-ypN0 group, patients with TRG1-ypN+ had a higher risk of recurrence (51.9 versus 39.6%; P < 0.001) and worse mean overall survival (33 versus 41 months; P < 0.001). CONCLUSION: Improved tumour response to neoadjuvant therapy was associated with lower recurrence rates and higher overall survival rates. Among patients with recurrent disease, TRG1 was associated with a higher incidence of brain recurrence than TRG>1. Residual nodal disease influenced prognosis more negatively than residual disease at the primary tumour site.

The prognostic value of a geriatric risk score for older patients undergoing emergency surgery of colorectal cancer: A retrospective cohort study.

INTRODUCTION: Emergency surgery of colorectal cancer is associated with high mortality rates in older patients. We investigated whether information on four geriatric domains has prognostic value for 30-day mortality and postoperative morbidity including severe complications. MATERIALS AND METHODS: All consecutive patients aged 70 years or older who underwent emergency colorectal cancer surgery in six Dutch hospitals (2014-2017) were studied. Presence of geriatric risk factors was scored prior to surgery as either 0 (risk absent) or 1 (risk present) in each of four geriatric domains and summed up to calculate a sumscore with a value between 0 and 4. In addition, we separately investigated the use of a mobility aid. Primary outcome was 30-day mortality. Secondary outcomes were any postoperative complications and severe complications. Multivariable logistic regression model was used to evaluate the sumscore and outcomes. RESULTS: Two hundred seven patients were included. Median age was 79.4 years. One hundred seventy-five patients (76%) presented with obstruction, 22 (11%) with a perforation, and 17 (8%) with severe anemia. Mortality rates were 2.9%, 13.6%, and 29.6% for patients with a sumscore of 0, 1-2, and 3-4 respectively, with odds ratio (OR) 4.8 [95% confidence interval (CI) 1.03-22.95] and OR 10.6 [95% CI 1.99-56.34] for a sumscore of 1-2 and 3-4 respectively. Use of a mobility aid was associated with increased mortality OR 8.0 [95% CI 2.74-23.43] and severe complications OR 2.31 [95% CI 1.17-4.55]. DISCUSSION: This geriatric sumscore and the use of a mobility aid have strong association with 30-day mortality after emergency surgery of colorectal cancer. This could provide better insight into surgical risk and help select high-risk patients for alternative strategies.

Evolution of surgical approach to rectal cancer resection: A multinational registry assessment.

PURPOSE: Surgical approach to rectal cancer has evolved in recent decades, with introduction of minimally invasive surgery (MIS) techniques and local excision. Since implementation might differ internationally, this study is aimed at evaluating trends in surgical approach to rectal cancer across different countries over the last 10 years and to gain insight into patient, tumour and treatment characteristics. METHODS: Pseudo-anonymised data of patients undergoing resection for rectal cancer between 2010 and 2019 were extracted from clinical audits in the Netherlands (NL), Sweden (SE), England-Wales (EW) and Australia-New Zealand (AZ). RESULTS: Ninety-nine thousand five hundred ninety-seven patients were included (38,413 open, 55,155 MIS and 5416 local excision). An overall increase in MIS was observed from 29.9% in 2010 to 72.1% in 2019, with decreasing conversion rates (17.5-9.0%). The MIS proportion was highly variable between countries in the period 2010-2014 (54.4% NL, 45.3% EW, 39.8% AZ, 14.1% SE, P < 0.001), but variation reduced over time (2015-2019 78.8% NL, 66.3% EW, 64.3% AZ, 53.2% SE, P < 0.001). The proportion of local excision for the two periods was highly variable between countries: 4.7% and 11.8% in NL, 3.9% and 7.4% in EW, 4.7% and 4.6% in AZ, 6.0% and 2.9% in SE. CONCLUSIONS: Application and speed of implementation of MIS were highly variable between countries, but each registry demonstrated a significant increase over time. Local excision revealed inconsistent trends over time.

Two Days Versus Five Days of Postoperative Antibiotics for Complex Appendicitis: Cost Analysis of a Randomized, Noninferiority Trial.

OBJECTIVE: To compare costs for 2 days versus 5 days of postoperative antibiotics within the antibiotics after an aPPendectomy In Complex appendicitis trial.Background:Recent studies suggest that restrictive antibiotic use leads to a significant reduction in hospital stays without compromising patient safety. Its potential effect on societal costs remains underexplored. METHODS: This was a pragmatic, open-label, multicenter clinical trial powered for noninferiority. Patients with complex appendicitis (age ≥ 8 years) were randomly allocated to 2 days or 5 days of intravenous antibiotics after appendectomy. Patient inclusion lasted from June 2017 to June 2021 in 15 Dutch hospitals. The final follow-up was on September 1, 2021. The primary trial endpoint was a composite endpoint of infectious complications and mortality within 90 days. In the present study, the main outcome measures were overall societal costs (comprising direct health care costs and costs related to productivity loss) and cost-effectiveness. Direct health care costs were recorded based on data in the electronic patient files, complemented by a telephone follow-up at 90 days. In addition, data on loss of productivity were acquired through the validated Productivity Cost Questionnaire at 4 weeks after surgery. Cost estimates were based on prices for the year 2019. RESULTS: In total, 1005 patients were evaluated in the "intention-to-treat" analysis: 502 patients were allocated to the 2-day group and 503 to the 5-day group. The mean difference in overall societal costs was - €625 (95% CI: -€ 958 to -€ 278) to the advantage of the 2-day group. This difference was largely explained by reduced hospital stay. Productivity losses were similar between the study groups. Restricting postoperative antibiotics to 2 days was cost-effective, with estimated cost savings of €31,117 per additional infectious complication. CONCLUSIONS: Two days of postoperative antibiotics for complex appendicitis results in a statistically significant and relevant cost reduction, as compared with 5 days. Findings apply to laparoscopic appendectomy in a well-resourced health care setting.

Determinants of Physical Activity among Patients with Colorectal Cancer: From Diagnosis to 5 Years after Diagnosis.

INTRODUCTION: Physical activity (PA) is associated with higher quality of life and probably better prognosis among colorectal cancer (CRC) patients. This study focuses on determinants of PA among CRC patients from diagnosis until 5 yr postdiagnosis. METHODS: Sociodemographic and disease-related factors of participants of two large CRC cohort studies were combined. Moderate-to-vigorous PA during sport and leisure time (MVPA-SL) was measured at diagnosis (T0) and 6, 12, 24, and 60 months (T6 to T60) postdiagnosis, using the SQUASH questionnaire. Mixed-effects models were performed to identify sociodemographic and disease-related determinants of MVPA-SL, separately for stage I-III colon (CC), stage I-III rectal cancer (RC), and stage IV CRC (T0 and T6 only). Associations were defined as consistently present when significant at ≥4 timepoints for the stage I-III subsets. MVPA-SL levels were compared with an age- and sex-matched sample of the general Dutch population. RESULTS: In total, 2905 CC, 1459 RC and 436 stage IV CRC patients were included. Patients with higher fatigue scores, and women compared with men had consistently lower MVPA-SL levels over time, regardless of tumor type and stage. At T6, having a stoma was significantly associated with lower MVPA-SL among stage I-III RC patients. Systemic therapy and radiotherapy were not significantly associated with MVPA-SL changes at T6. Compared with the general population, MVPA-SL levels of CRC patients were lower at all timepoints, most notably at T6. CONCLUSIONS: Female sex and higher fatigue scores were consistent determinants of lower MVPA-SL levels among all CRC patients, and MVPA-SL levels were lowest at 6 months postdiagnosis. Our results can inform the design of intervention studies aimed at improving PA, and guide healthcare professionals in optimizing individualized support.

Uptake of robot-assisted colon cancer surgery in the Netherlands.

BACKGROUND: The robot-assisted approach is now often used for rectal cancer surgery, but its use in colon cancer surgery is less well defined. This study aims to compare the outcomes of robotic-assisted colon cancer surgery to conventional laparoscopy in the Netherlands. METHODS: Data on all patients who underwent surgery for colon cancer from 2018 to 2020 were collected from the Dutch Colorectal Audit. All complications, readmissions, and deaths within 90 days after surgery were recorded along with conversion rate, margin and harvested nodes. Groups were stratified according to the robot-assisted and laparoscopic approach. RESULTS: In total, 18,886 patients were included in the analyses. The operative approach was open in 15.2%, laparoscopic in 78.9% and robot-assisted in 5.9%. The proportion of robot-assisted surgery increased from 4.7% in 2018 to 6.9% in 2020. There were no notable differences in outcomes between the robot-assisted and laparoscopic approach for Elective cT1-3M0 right, left, and sigmoid colectomy. Only conversion rate was consistently lower in the robotic group. (4.6% versus 8.8%, 4.6% versus 11.6%, and 1.6 versus 5.9%, respectively). CONCLUSIONS: This nationwide study on surgery for colon cancer shows there is a gradual but slow adoption of robotic surgery for colon cancer up to 6.9% in 2020. When comparing the outcomes of right, left, and sigmoid colectomy, clinical outcomes were similar between the robotic and laparoscopic approach. However, conversion rate is consistently lower in the robotic procedures.

Esophageal cancer patients' need for information and support in making a treatment decision between standard surgery and active surveillance.

BACKGROUND: This study explores patients' need for information and support in deciding on esophageal cancer treatment, when experimental active surveillance and standard surgery are both feasible. METHODS: This psychological companion study was conducted alongside the Dutch SANO-trial (Surgery As Needed for Oesophageal cancer). In-depth interviews and questionnaires were used to collect data from patients who declined participation in the trial because they had a strong preference for either active surveillance (n = 20) or standard surgery (n = 20). Data were analyzed using both qualitative and quantitative techniques. RESULTS: Patients prefer to receive information directly from their doctors and predominantly rely on this information to make a treatment decision. Other information resources are largely used to confirm their treatment decision. Patients highly value support from their loved ones and appreciate emphatic doctors to actively involve them in the decision-making process. Overall, patients' needs for information and support during decision-making were met. CONCLUSIONS: The importance of shared decision-making and the role doctors have in this process is underlined. The role of doctors is essential at the initial phase of decision-making: Once patients seem to have formed their treatment preference for either active surveillance or surgery, the influence of external resources (including doctors) may be limited.
