Abstract
Introduction Advancements in rectal cancer (RC) treatment not only led to an increase in lives saved but also improved quality of life (QoL). Notwithstanding these benefits, RC treatment comes at the price of gastrointestinal morbidity in many patients. Health economic modelling poses an opportunity to explore the societal burden of such side-effects. This study aims to quantify radiation-induced late small bowel (SB) toxicity in survivors of RC for Three-Dimensional Conformal Radiation Therapy (3D-CRT), Intensity Modulated Radiation Therapy (IMRT) and Intensity Modulated Radiation Therapy - Image Guided Radiation Therapy (IMRT/IGRT). Materials and methods Materials and A model-based health economic evaluation was performed. The theoretical cohort consists of a case-mix of survivors of RC aged 25-99 years according to Belgian age-specific incidence rates. A societal perspective was adopted. The base case analysis was complemented with one-way deterministic analyses, deterministic scenario analyses and probabilistic sensitivity analysis (1,000 iterations). Results were presented as mean lifetime incremental cost (€) and utility (QALYs) per patient. Results The analyses showed that the use of innovative radiotherapy (RT) improves lifetime QoL in survivors of RC by 0.11 QALYs and 0.05 QALYs by preferring IMRT/IGRT and IMRT over 3D-CRT, respectively. The use of IMRT/IGRT and IMRT results in an incremental cost-saving of €3,820 and €1,863 per patient, solely by radiation-induced SB toxicity, compared to 3D-CRT. Discussion and conclusion It is important to consider late toxicity effects in decisions regarding investments and reimbursement as our analysis highlighted the potential long-term cost-savings and improved QoL of novel RT techniques in patients with rectal cancer.

Bowel dysfunction following pelvic organ cancer: a prospective study on the treatment effect in nurse-led late sequelae clinics. Acta Oncol 2023; 62:70-79. [PMID: 36757368 DOI: 10.1080/0284186x.2023.2168214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/10/2023]
Abstract
BACKGROUND Bowel dysfunction following treatment of pelvic organ cancer is prevalent and impacts the quality of life (QoL). The present study aimed to evaluate the feasibility and effects of treating bowel dysfunction in two nurse-led late sequelae clinics. MATERIAL AND METHODS Treatment effects were monitored prospectively by patient-reported outcome measures collected at baseline and discharge. Change in bowel function was evaluated by 15 bowel symptoms, the St. Mark's Incontinence Score, the Patients Assessment of Constipation-Symptoms (PAC-SYM) score and self-rated bowel function. QoL was evaluated by the EuroQol 5-dimension 5-level (EQ-5D-5L) utility score and by measuring the impact of bowel function on QoL. RESULTS From June 2018 to December 2021, 380 cancer survivors (46% rectal, 15% gynaecological, 13% anal, 12% colon, 12% prostate, and 2% other cancers) completed a baseline questionnaire and started treatment for bowel dysfunction. At referral, 96% of patients were multisymptomatic. The most frequent symptoms were faecal urgency (95%), fragmented defaecation (93%), emptying difficulties (92%), flatus/faecal incontinence (flatus 89%, liquid 59%, solid 33%), and obstructed defaecation (79%). In total, 169 patients were discharged from the clinics in the follow-up period. At discharge, 69% received conservative treatment only and 24% also received transanal irrigation; 4% were surgically treated; 3% discontinued treatment. Improvements were seen in all 15 bowel symptoms (p < 0.001), the mean St. Mark's Incontinence Score (12.0 to 9.9, p < 0.001), the mean PAC-SYM score (1.04 to 0.84, p < 0.001) and the mean EQ-5D-5L utility score (0.78 to 0.84, p < 0.001). Self-rated bowel function improved in 56% (p < 0.001) of cases and the impact of bowel function on QoL improved in 46% (p < 0.001). CONCLUSION Treatment of bowel dysfunction in nurse-led late sequelae clinics is feasible and significantly improved bowel function and QoL.

Abstract
Immune checkpoint inhibitors herald a new era in oncological therapy-resistant cancer, thus bringing hope for better outcomes and quality of life for patients. However, as with other medications, they are not without serious side effects over time. Despite this, their advantages outweigh their disadvantages. Understanding the adverse effects will help therapists locate, apprehend, treat, and perhaps diminish them. The major ones are termed immune-related adverse events (irAEs), representing their auto-immunogenic capacity. This narrative review concentrates on the immune checkpoint inhibitors induced celiac disease (CD), highlighting the importance of the costimulatory inhibitors in CD evolvement and suggesting several mechanisms for CD induction. Unraveling those cross-talks and pathways might reveal some new therapeutic strategies.
