Towards patient-led follow-up after curative surgical resection of stage I, II and III colorectal cancer (DISTANCE-trial): a study protocol for a stepped-wedge cluster-randomised trial

BACKGROUND

Colorectal cancer (CRC) is among the most frequently diagnosed cancers. Approximately 20-30% of stage I-III CRC patients develop a recurrent tumour or metastases after curative surgical resection. Post-operative follow-up is indicated for the first five years after curative surgical resection. As intensified follow-up after curative surgical resection has shown no effect on survival, patient organisations and policy makers have advocated for a more patient-centred approach to follow-up. The objective of this study is to successfully implement patient-led, home-based follow-up (PHFU) in six hospitals in The Netherlands, with as ultimate aim to come to a recommendation for a patient-centred follow-up schedule for stage I-III CRC patients treated with surgical resection with curative intent.

METHODS

This study is designed as a stepped-wedge cluster-randomised trial (SW-CRT) in six participating centres. During the trial, three centres will implement PHFU after six months; the other three centres will implement PHFU after 12 months of inclusion in the control group. Eligible patients are those with pT2-4N0M0 or pT1-4N1-2M0 CRC, who are 18 years or older and have been free of disease for 12 months after curative surgical resection. The studied intervention is PHFU, starting 12 months after curative resection. The in-hospital, standard-of-care follow-up currently implemented in the participating centres functions as the comparator. The proportion of patients who had contact with the hospital regarding CRC follow-up between 12-24 months after curative surgical resection is the primary endpoint of this study. Quality of life, fear of cancer recurrence, patient satisfaction, cost-effectiveness and survival are the secondary endpoints.

DISCUSSION

The results of this study will provide evidence on whether nationwide implementation of PHFU for CRC in The Netherlands will be successful in reducing contact between patient and health care provider. Comparison of PROMs between in-hospital follow-up and PHFU will be provided. Moreover, the cost-effectiveness of PHFU will be assessed.

Delayed surgical resection of primary left-sided obstructing colon cancer is associated with improved short- and long-term outcomes

BACKGROUND AND OBJECTIVES

It is unclear what time interval is optimal between presentation and surgical resection of left-sided obstructive colon cancer (LSOCC). This study aims to determine whether a time interval beyond 4 weeks is associated with a better outcome.

MATERIALS AND METHODS

Consecutive patients who underwent surgical resection of LSOCC between January 2010 and December 2019 were collected from a prospective database. Patients were divided into three groups: (1) Emergency resection (ER group), (2) surgery in less than 4 weeks (early group), and (3) surgery beyond 4 weeks (late group).

RESULTS

The ER group consisted of 74 (44.0%), the early group of 38 (22.6%), and the late group of 56 (33.3%) patients. Ninety-day mortality was lower in the Late group than in the ER group and the early group (1.8% vs. 12.2%, p = 0.029 vs. 15.3%, p = 0.011). In the late group 5-year recurrence-free survival was better than in the early group (82.1% vs. 63.2%, p = 0.039) and 5-year overall survival (OS) was better than in the ER group (75% vs. 51.4%, p = 0.021). Definitive surgical resection beyond 4 weeks was an independent prognostic factor for OS (Hazard ratio: 0.402, 95% CI: 0.204-0.793, p = 0.009).

CONCLUSION

In this study surgical resection beyond 4 weeks after presentation seems to have a better short- and long-term outcome for LSOCC.

Implementation of robot-assisted total mesorectal excision by multiple surgeons in a large teaching hospital: Morbidity, long-term oncological and functional outcome

BACKGROUND

Robot-assisted total mesorectal excision (TME) might offer benefits in less morbidity, better functional and long-term outcome over laparoscopic TME.

METHODS

All consecutive patients undergoing robot-assisted TME for rectal cancer during implementation between May 2015 and December 2019 performed by five surgeons in a single centre were included. Outcomes included local recurrence rate at 3 years, conversion rate, circumferential resection margin (CRM) positivity rate, 30-day postoperative morbidity and outcomes of low anterior resection syndrome (LARS) questionnaires.

RESULTS

In 105 robot-assisted TME, local recurrence rate at 3 years was 7.4%, conversion to open surgery rate was 8.6%, CRM positivity rate was 5.7%, 73.3% had good quality specimen, postoperative morbidity rate was 47.6% and anastomotic leakage rate was 9.0%. Incidence of major LARS was 55.3%.

CONCLUSIONS

results of this study described acceptable morbidity, functional and long-term outcome during implementation of robotic TME for rectal cancer by multiple surgeons in a single centre.

Oncological outcomes of unsuspected pN2 in patients with non-small-cell lung cancer: a systematic review and meta-analysis

OBJECTIVES

Optimal treatment of stage IIIA (N2) non-small-cell lung cancer (NSCLC) is controversial. Guidelines advise induction therapy before surgical resection. A proportion of patients with cN0 NSCLC are postoperatively upstaged due to unsuspected N2 disease. Survival of unsuspected N2 NSCLC treated with surgery varies and technical feasibility of video-assisted thoracic surgery (VATS) is unknown. The purpose of this study was to assess prevalence and survival of unsuspected N2 NSCLC treated with thoracotomy or VATS.

METHODS

A systematic review and meta-analysis was performed of all available literatures through Pubmed, Cochrane, EMBASE, Web of Science, Trials registries and System for Information on Grey Literature (SIGLE) from 2000 to 2019. Outcomes of interest were prevalence, overall survival (OS) and disease-free survival of unsuspected N2 NSCLC. Secondary outcomes were number of harvested lymph nodes, postoperative complications and survival of unsuspected N2 NSCLC treated with VATS.

RESULTS

Seventeen studies with patients with clinical stage N0-1 and unsuspected pN2 NSCLC were included. Prevalence of unsuspected pN2 was 8.6%. Three- and 5-year OS was 58% [95% confidence interval (CI) 37-78%) (N = 4337] and 35% (95% CI 28-43%) (N = 4337). Three- and 5-y ear disease-free survival was 48% (95% CI 30-66%) (N = 109) and 35% (95% CI 24-46%) (N = 517). VATS resulted in a low complication rate with similar 5-year OS as thoracotomy.

CONCLUSIONS

In patients with cN0-1 NSCLC, a minority has unsuspected pN2 NSCLC. Even for these patients, 5-year OS and disease-free survival are reasonable. VATS with adequate lymph node dissection is the treatment of choice when in experienced hands. Adjuvant therapy should be provided in absence of relevant comorbidity.

The impact of postoperative complications on health-related quality of life in older patients with rectal cancer; a prospective cohort study

OBJECTIVES

As result of the aging population and increasing rectal cancer incidence, more older patients undergo treatment for rectal cancer. This study compares treatment course, postoperative complications, and quality of life (QOL) between older and younger patients with rectal cancer and evaluates the impact of postoperative complications on QOL in the elderly.

MATERIALS AND METHODS

Patients with rectal cancer participating in a prospective colorectal cancer cohort and referred for radiotherapy between 2013 and 2016 were included. QOL was assessed with the cancer questionnaire of the European Organisation for Research and Treatment of Cancer (EORTC QLQ-C30) before treatment and at three, six, and twelve months. Outcomes were compared between older patients (≥70years) and younger patients (<70years) and stratified by presence of postoperative complications.

RESULTS

In total, 115 (33%) older patients and 230 (67%) younger patients were included. Compared to younger patients, older patients underwent significantly more often short-course radiation with delayed surgery (6.1% and 19.1% respectively) and less often chemoradiation (62.6% and 39.1% respectively), and were more likely to undergo a Hartmann procedure with permanent stoma (3.5% and 13.0% respectively) instead of sphincter-sparing surgery (43.9% and 29.6% respectively). Postoperative complication rates were similar (38.5% in older patients versus 34.7% in younger patients). Older patients had worse physical functioning at six and twelve months after diagnosis compared to younger patients. Presence of postoperative complications had a significant stronger impact on physical- and role functioning in older patients.

CONCLUSION

Older patients undergo more often a tailored treatment approach for rectal cancer than younger patients. With this tailored approach, similar postoperative complication rates and QOL are achieved. However, postoperative complications have a larger negative impact on physical- and role functioning in older patients which indicates a need for better prediction of postoperative complications in the elderly.

Cost-effectiveness analysis of an 18-week exercise programme for patients with breast and colon cancer undergoing adjuvant chemotherapy: the randomised PACT study

OBJECTIVE

Meta-analyses show that exercise interventions during cancer treatment reduce cancer-related fatigue. However, little is known about the cost-effectiveness of such interventions. Here we aim to assess the cost-effectiveness of the 18-week physical activity during cancer treatment (PACT) intervention for patients with breast and colon cancer. The PACT trial showed beneficial effects for fatigue and physical fitness.

DESIGN

Cost-effectiveness analyses with a 9-month time horizon (18 weeks of intervention and 18 weeks of follow-up) within the randomised controlled multicentre PACT study.

SETTING

Outpatient clinics of 7 hospitals in the Netherlands (1 academic and 6 general hospitals) PARTICIPANTS: 204 patients with breast cancer and 33 with colon cancer undergoing adjuvant treatment including chemotherapy.

INTERVENTION

Supervised 1-hour aerobic and resistance exercise (twice per week for 18 weeks) or usual care.

MAIN OUTCOME MEASURES

Costs, quality-adjusted life years (QALY) and the incremental cost-effectiveness ratio.

RESULTS

For colon cancer, the cost-effectiveness analysis showed beneficial effects of the exercise intervention with incremental costs savings of €4321 and QALY improvements of 0.03. 100% of bootstrap simulations indicated that the intervention is dominant (ie, cheaper and more effective). For breast cancer, the results did not indicate that the exercise intervention was cost-effective. Incremental costs were €2912, and the incremental effect was 0.01 QALY. At a Dutch threshold value of €20 000 per QALY, the probability that the intervention is cost-effective was 2%.

CONCLUSIONS

Our results suggest that the 18-week exercise programme was cost-effective for colon cancer, but not for breast cancer.

Quality of Life After a Low Anterior Resection for Rectal Cancer in Elderly Patients

Purpose

Fecal incontinence is a major concern, and its incidence increases with age. Quality of life may decrease due to fecal incontinence after both sphincter-saving surgery and a rectal resection with a permanent stoma. This study investigated quality of life, with regard to fecal incontinency, in elderly patients after rectal-cancer surgery.

Methods

All patients who underwent elective rectal surgery with anastomosis for rectal cancer between December 2008 and June 2012 at two Dutch hospitals were eligible for inclusion. The Wexner and the fecal incontinence quality of life (FIQoL) scores were collected. Young (<70 years of age) and elderly (≥70 years of age) patients were compared.

Results

Seventy-nine patients were included, of whom 19 were elderly patients (24.1%). All diverting stomas that had been placed (n = 60, 75.9%) had been closed at the time of the study. There were no differences in Wexner or FIQoL scores between the young and the elderly patients. Also, there were no differences between patients without a diverting stoma and patients in whom bowel continuity had been restored. Elderly females had significantly worse scores on the FIQoL subscales of coping/behavior (P = 0.043) and depression/self-perception (P = 0.004) than young females. Elderly females scored worse on coping/behavior (P = 0.010) and depression/self-perception (P = 0.036) than elderly males. Young and elderly males had comparable scores.

Conclusion

Quality of life with regard to fecal incontinency is worse in elderly females after sphincter-preserving surgery for rectal cancer. Patients should be informed of this impact, and a definite stoma may be considered in this patient group.

Effects of an 18-week exercise programme started early during breast cancer treatment: a randomised controlled trial

BACKGROUND

Exercise started shortly after breast cancer diagnosis might prevent or diminish fatigue complaints. The Physical Activity during Cancer Treatment (PACT) study was designed to primarily examine the effects of an 18-week exercise intervention, offered in the daily clinical practice setting and starting within 6 weeks after diagnosis, on preventing an increase in fatigue.

METHODS

This multi-centre controlled trial randomly assigned 204 breast cancer patients to usual care (n = 102) or supervised aerobic and resistance exercise (n = 102). By design, all patients received chemotherapy between baseline and 18 weeks. Fatigue (i.e., primary outcome at 18 weeks), quality of life, anxiety, depression, and physical fitness were measured at 18 and 36 weeks.

RESULTS

Intention-to-treat mixed linear model analyses showed that physical fatigue increased significantly less during cancer treatment in the intervention group compared to control (mean between-group differences at 18 weeks: -1.3; 95 % CI -2.5 to -0.1; effect size -0.30). Results for general fatigue were comparable but did not reach statistical significance (-1.0, 95%CI -2.1; 0.1; effect size -0.23). At 18 weeks, submaximal cardiorespiratory fitness and several muscle strength tests (leg extension and flexion) were significantly higher in the intervention group compared to control, whereas peak oxygen uptake did not differ between groups. At 36 weeks these differences were no longer statistically significant. Quality of life outcomes favoured the exercise group but were not significantly different between groups.

CONCLUSIONS

A supervised 18-week exercise programme offered early in routine care during adjuvant breast cancer treatment showed positive effects on physical fatigue, submaximal cardiorespiratory fitness, and muscle strength. Exercise early during treatment of breast cancer can be recommended. At 36 weeks, these effects were no longer statistically significant. This might have been caused by the control participants' high physical activity levels during follow-up.

Predictors of fecal incontinence and related quality of life after a total mesorectal excision with primary anastomosis for patients with rectal cancer

Purpose

After total mesorectal excision (TME) with primary anastomosis for patients with rectal cancer, the quality of life (QoL) may be decreased due to fecal incontinence. This study aimed to identify predictors of fecal incontinence and related QoL.

Methods

Patients who underwent TME with primary anastomosis for rectal cancer between December 2008 and June 2012 completed the fecal incontinence quality of life scale (FIQoL) and Wexner incontinence score. Factors associated with these scores were identified using a linear regression analysis.

Results

A total of 80 patients were included. Multivariate analysis identified a diverting ileostomy (n = 58) as an independent predictor of an unfavorable outcome on the FIQoL subscale coping/behavior (P = 0.041). Ileostomy closure within and after 3 months resulted in median Wexner scores of 5.0 (interquartile range [IQR], 2.5-8.0) and 10.5 (IQR, 6.0-13.8), respectively (P < 0.001). The median FIQoL score was 15.0 (IQR, 13.1-16.0) for stoma closure within 3 months versus 12.0 (IQR, 10.5-13.9) for closure after 3 months (P = 0.001).

Conclusion

A diverting ileostomy is a predictor for an impaired FIQoL after a TME for rectal cancer. Stoma reversal within 3 months showed better outcomes than reversal after 3 months. Patients with a diverting ileostomy should be informed about the impaired QoL, even after stoma closure.

Breast cancer surgery without drains: no influence on seroma formation

It is not clear whether drains are necessary after breast cancer surgery. The purpose of this study was to compare seroma formation in patients that had postoperative drainage for 24 h with patients that had no drain after breast cancer surgery. In this retrospective cohort study 96 patients with a primary breast cancer were included. Between January 2009 and April 2011 44 patients had breast cancer surgery followed by postoperative drainage. Between May 2011 and February 2013 52 patients underwent breast cancer surgery without drainage. The operative procedures that were included were: axillary lymph node dissection, modified radical mastectomy or simple mastectomy±sentinel lymph node biopsy. There was no difference between both groups regarding frequency of seroma (84.6% versus 90.9%; p=0.290) and amount of seroma (540 ml versus 590 ml; p=0.446). Postoperative hospital stay was shorter in patients without drainage (2 versus 2.5 days; p=0.003). There was no difference between both groups in other secondary outcome measures. Modified radical mastectomy was an independent predictor of the amount of postoperative seroma (HR 0.039 [0.007-0.235]; p<0.001). These results suggest that there is no difference in seroma after breast cancer surgery between patients that had postoperative drainage and patients that had no postoperative drainage.
