Quality of life outcomes in patients undergoing surgery for locally recurrent rectal cancer

Dutch national guidelines for locally recurrent rectal cancer

Due to improvements in treatment for primary rectal cancer, the incidence of LRRC has decreased. However, 6-12% of patients will still develop a local recurrence. Treatment of patients with LRRC can be challenging, because of complex and heterogeneous disease presentation and scarce - often low-grade - data steering clinical decisions. Previous consensus guidelines have provided some direction regarding diagnosis and treatment, but no comprehensive guidelines encompassing all aspects of the clinical management of patients with LRRC are available to date. The treatment of LRRC requires a multidisciplinary approach and overarching expertise in all domains. This broad expertise is often limited to specific expert centres, with dedicated multidisciplinary teams treating LRRC. A comprehensive, narrative literature review was performed and used to develop the Dutch National Guideline for management of LRRC, in an attempt to guide decision making for clinicians, regarding the complete clinical pathway from diagnosis to surgery.

Factors Associated with Deterioration in Quality of Life of Subjects after Maxillofacial Fractures - A Prospective Study

Introduction

Maxillofacial fractures (MFs) are quite common and are managed by oral and maxillofacial surgeons. Despite these interventions, a pre-traumatic facial profile is often not achieved with consequent social and psychologic consequences.

Materials and Methods

Patients with fractures to the middle and lower third of the face that presented within 48 hours and healthy controls (subjects without facial fracture) that were sex- and age-matched with the fracture patients were recruited into the study. World Health Organization Quality of Life - Brief Version (WHOQOL-BREF) questionnaire was used to compare the Quality of Life (QoL) values according to age, gender, educational status, employment status, marital status, site of trauma and type of fracture.

Results

Only the age of subjects was associated with deterioration in QoL after MF while other variables were not.

Discussion

Increasing age of the patients was associated with higher QoL possibly because those with age <30 years are single and unemployed and may have fear and anxiety that the fracture could affect their chances of getting married or being employed, causing reduced QoL. Psychosocial rehabilitation is very important in patients with MF, especially for the young age group.

Short-term outcomes of health-related quality of life in patients with locally recurrent rectal cancer: multicentre, international, cross-sectional cohort study

BACKGROUND

Overall survival rates for locally recurrent rectal cancer (LRRC) continue to improve but the evidence concerning health-related quality of life (HrQoL) remains limited. The aim of this study was to describe the short-term HrQoL differences between patients undergoing surgical and palliative treatments for LRRC.

METHODS

An international, cross-sectional, observational study was undertaken at five centres across the UK and Australia. HrQoL in LRRC patients was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-CR29 and functional assessment of cancer therapy - colorectal (FACT-C) questionnaires and subgroups (curative versus palliative) were compared. Secondary analyses included the comparison of HrQoL according to the margin status, location of disease and type of treatment. Scores were interpreted using minimal clinically important differences (MCID) and Cohen effect size (ES).

RESULTS

Out of 350 eligible patients, a total of 95 patients participated, 74.0 (78.0 per cent) treated with curative intent and 21.0 (22.0 per cent) with palliative intent. Median time between LRRC diagnosis and HrQoL assessments was 4 months. Higher overall FACT-C scores denoting better HrQoL were observed in patients undergoing curative treatment, demonstrating a MCID with a mean difference of 18.5 (P < 0.001) and an ES of 0.6. Patients undergoing surgery had higher scores denoting a higher burden of symptoms for the EORTC CR29 domains of urinary frequency (P < 0.001, ES 0.3) and frequency of defaecation (P < 0.001, ES 0.4). Higher overall FACT-C scores were observed in patients who underwent an R0 resection versus an R1 resection (P = 0.051, ES 0.6). EORTC CR29 scores identified worse body image in patients with posterior/central disease (P = 0.021). Patients undergoing palliative chemoradiation reported worse HrQoL scores with a higher symptom burden on the frequency of defaecation scale compared with palliative chemotherapy (P = 0.041).

CONCLUSION

Several differences in short-term HrQoL outcomes between patients undergoing curative and palliative treatment for LRRC were documented. Patients undergoing curative surgery reported better overall HrQoL and a higher burden of pelvic symptoms.

MRI tumour regression grade in locally recurrent rectal cancer

BACKGROUND

This study aimed to investigate the agreement between magnetic resonance tumour regression grade (mrTRG) and pathological regression grade (pTRG) in patients with locally recurrent rectal cancer (LRRC). Also, the reproducibility of mrTRG was investigated.

METHODS

All patients with LRRC who underwent a resection between 2010 and 2018 after treatment with induction chemotherapy and neoadjuvant chemo(re)irradiation in whom a restaging MRI was available were retrospectively selected. All MRI scans were reassessed by two independent radiologists using the mrTRG, and the pTRG was reassessed by an independent pathologist. The interobserver agreement between the radiologists as well as between the radiologists and the pathologist was assessed with the weighted kappa test. A subanalysis was performed to evaluate the influence of the interval between imaging and surgery.

RESULTS

Out of 313 patients with LRRC treated during the study interval, 124 patients were selected. Interobserver agreement between the radiologists was fair (k = 0.28) using a two-tier grading system (mrTRG 1-2 versus mrTRG 3-5). For the lead radiologist, agreement with pTRG was moderate (k = 0.52; 95 per cent c.i. 0.36 to 0.68) when comparing good (mrTRG 1-2 and Mandard 1-2) and intermediate/poor responders (mrTRG 3-5 and Mandard 3-5), and the agreement was fair between the other abdominal radiologist and pTRG (k = 0.39; 95 per cent c.i. 0.22 to 0.56). A shorter interval (less than 7 weeks) between MRI and surgery resulted in an improved agreement (k = 0.69), compared with an interval more than 7 weeks (k = 0.340). For the lead radiologist, the positive predictive value for predicting good responders was 95 per cent (95 per cent c.i. 71 per cent to 99 per cent), whereas this was 56 per cent (95 per cent c.i. 44 per cent to 66 per cent) for the other radiologist.

CONCLUSION

This study showed that, in LRRC, the reproducibility of mrTRG among radiologists is limited and the agreement of mrTRG with pTRG is low. However, a shorter interval between MRI and surgery seems to improve this agreement and, if assessed by a dedicated radiologist, mrTRG could predict good responders.

Clinical selection strategy for and evaluation of intra-operative brachytherapy in patients with locally advanced and recurrent rectal cancer

BACKGROUND AND PURPOSE

A radical resection of locally advanced rectal cancer (LARC) or recurrent rectal cancer (RRC) can be challenging. In case of increased risk of an R1 resection, intra-operative brachytherapy (IOBT) can be applied. We evaluated the clinical selection strategy for IOBT.

MATERIALS AND METHODS

Between February 2007 and May 2018, 132 LARC/RRC patients who were scheduled for surgery with IOBT standby, were evaluated. By intra-operative inspection of the resection margin and MR imaging, it was determined whether a resection was presumed to be radical. Frozen sections were taken on indication. In case of a suspected R1 resection, IOBT (1 × 10 Gy) was applied. Histopathologic evaluation, treatment and toxicity data were collected from medical records.

RESULTS

Tumour was resected in 122 patients. IOBT was given in 42 patients of whom 54.8% (n = 23) had a histopathologically proven R1 resection. Of the 76 IOBT-omitted R0 resected patients, 17.1% (n = 13) had a histopathologically proven R1 resection. In 4 IOBT-omitted patients, a clinical R1/2 resection was seen. In total, correct clinical judgement occurred in 72.6% (n = 88) of patients. In LARC, 58.3% (n = 14) of patients were overtreated (R0, with IOBT) and 10.9% (n = 5) were undertreated (R1, without IOBT). In RRC, 26.5% (n = 9) of patients were undertreated.

CONCLUSION

In total, correct clinical judgement occurred in 72.6% (n = 88). However, in 26.5% (n = 9) RRC patients, IOBT was unjustifiedly omitted. IOBT is accompanied by comparable and acceptable toxicity. Therefore, we recommend IOBT to all RRC patients at risk of an R1 resection as their salvage treatment.
