Management of treatment-related sequelae following colorectal cancer.

AIM: Colorectal cancer survivors are one of the most rapidly growing groups of patients living with and beyond cancer. In a national multidisciplinary setting, we have examined the extent of late treatment-related sequelae in colorectal cancer survivors and present the scientific evidence for management of these conditions in this patient category with the aim of facilitating identification and treatment. METHOD: A systematic search for existing guidelines and relevant studies was performed across 16 and 4 databases, respectively, from inception to 2021. This yielded 13 guidelines and 886 abstracts, of which 188 were included in the finalized guideline (231 included for full text review). Secondarily, bibliographies were cross-referenced and 53 additional articles were included. RESULTS: Symptoms have been divided into overall categories including psychosocial, bowel-related, urinary, sexual (male and female), pain/neuropathy and fatigue symptoms or complaints that are examined individually. Merging and grading of data resulted in 22 recommendations and 42 management strategies across categories. Recommendations are of a more general character, whereas management strategies provide more practical advice suited for initiation on site before referral to specialized units. CONCLUSION: Treatment-related sequelae in colorectal cancer survivors are common and attention needs to be focused on identifying patients with unmet treatment needs and the development of evidence-based treatment algorithms.

Danish translation and qualitative validation of the Measure Yourself Medical Outcome Profileand the Measure Yourself Concerns and Wellbeing.

INTRODUCTION: Patients may experience late complications following surgical treatment for colorectal and anal cancer, and we need instruments in Danish to plan treatment and person-centred follow-up treatment approaches. For this purpose, we chose the Measure Yourself Medical Outcome Profile (MYMOP) and Measure Yourself Concerns and Wellbeing (MYCaW). The aim of this study was to translate the two instruments into Danish and conduct a subsequent qualitative validation. METHODS: The translation process consists of five stages: forward translation, synthesis, back translation, expert panel review and pretesting. Qualitative validation included interview with target audience representatives, testing of face-validity and evaluation by lay persons. RESULTS: Through the translation process and qualitative validation, we produced Danish versions of the MYMOP and the MYCaW. CONCLUSIONS: The Danish versions of the two questionnaires are now ready for use in clinical practice and research after individual licensing consultation with the copyright holders. FUNDING: none. TRIAL REGISTRATION: not relevant.

Management of late adverse effects after chemoradiation for anal cancer.

BACKGROUND AND PURPOSE: Significant improvements in the treatment of anal cancer have produced a growing population of anal cancer survivors. These patients often experience late adverse effects related to their treatment. Research has revealed substantial unmet needs because of long-term symptoms and functional impairments after treatment that may negatively affect health-related quality of life. The purpose of the present guidelines is to review the scientific evidence for the management of late adverse effects after (chemo)radiotherapy ([C]RT) for anal cancer and to extrapolate knowledge from other pelvic malignancies treated with pelvic (C)RT so that they may guide the clinical management of late adverse effects. MATERIALS AND METHODS: Relevant studies were systematically searched in four databases from their inception to June 2020 (no language limitation) and guidelines were searched in 16 databases, focussing on bowel dysfunction, psychosocial aspects, pain, and sexual and urinary dysfunction. The guidelines were developed by a panel of experts using the Oxford Centre for Evidence-based Medicine, levels of evidence, and grades of recommendations. SCIENTIFIC EVIDENCE: Late adverse effects after (C)RT for anal cancer are associated with a low overall quality of life among survivors. The most pronounced late adverse effects are bowel dysfunction (present in up to 78%), urinary dysfunction (present in up to 45%), and sexual dysfunction (present in up to 90% of men and up to 100% of women). Only indirect data on adequate treatment options of these late adverse effects for anal cancer are available. CONCLUSION: Quality of life and late adverse effects should be monitored systematically following treatment for anal cancer to identify patients who require further specialist evaluation or support. Increased awareness of the extent of the problem may serve to stimulate and facilitate multidisciplinary collaboration, which is often required.
