Literature review: preoperative radiotherapy and rectal cancer - impact on acute symptom presentation and quality of life

Treatment trajectories of individuals diagnosed with rectal cancer: an interpretative phenomenological study

Rectal cancer affects almost every aspect of an individual's daily life. However, there are gaps in understanding the complete spectrum of experiences spanning from diagnosis to recovery. Therefore, the aim of this study was to explore the treatment trajectories of individuals diagnosed with rectal cancer. Adopting an interpretative phenomenological approach, seven participants were recruited using purposive sampling. Data were collected using semi-structured, in-depth interviews that were digitally recorded, transcribed and analysed using thematic analysis. Study rigour was established following the four-dimension criteria of credibility, dependability, transferability and confirmability. Four prominent themes emerged from the participants' experiences of undergoing rectal cancer treatment: uncovering the inner battles; navigating the physical challenges; anchors of support and conquering the summit. These findings contribute to knowledge and practice by highlighting the importance of providing a comprehensive and individualised treatment plan for individuals that takes account of the physical and psycho-emotional implications of rectal cancer treatment.

Evaluation of Depression, Anxiety, and Sexual Function in Rectal Cancer Patients Before and After Neoadjuvant Chemoradiotherapy

OBJECTIVE

The association of treatment-related side effects and tumor characteristics with sexual function, depression, and anxiety were investigated in patients with locally advanced rectum cancer (LARC) receiving neoadjuvant chemoradiotherapy (CRT).

MATERIAL AND METHODS

Thirty-two patients who received neoadjuvant CRT with LARC were included. The Arizona Sexual Experiences (ASEX) Scale was used to determine the sexual function status whereas the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI) were used to evaluate the depression and anxiety status of the patient, respectively. The patients were asked to fill these scales before and at least 4 weeks after the neoadjuvant CRT. T-test and Mann-Whitney U test were used for the comparison of values.

RESULTS

Median age was 52.5 years (range: 33-76). Twenty-six patients were male, and 6 patients were female. At presentation, the tumor was located mostly in lower third rectum (72%), and 69% of the patients had T3 tumors. There was a statistically significant deterioration in the sexual functions of the patients (p < 0.001), a statistically significant decrease in their anxiety level after CRT (p: 0.037). Depression level was changed from mild to minimal during this process (p: 0.17). A significant deterioration in the ASEX scale was observed especially in patients with grade 2 and above gastrointestinal side effects (p: 0.01).

CONCLUSION

This prospective study showed that the patient's anxiety and depression levels had decreased during the treatment process probably due to the decrease in the patient's symptoms. However, deterioration of the sexual function status which might be correlated to increased gastrointestinal side effects during CRT has been observed. So, clinical and psychiatric support including therapies for sexual dysfunctions is needed for LARC patients during and after the neoadjuvant CRT.

Effects of Exercise on Motivational Outcomes in Rectal Cancer Patients During and After Neoadjuvant Chemoradiation: A Phase II Randomized Controlled Trial

OBJECTIVES

Understanding exercise motivation in rectal cancer patients during and after neoadjuvant chemoradiation therapy is important to improve adherence and achieve potential benefit. We report the motivational effects of exercise from the Exercise During and After Neoadjuvant Rectal Cancer Treatment trial.

DATA SOURCES

We randomized 36 rectal cancer patients to supervised high-intensity interval training during neoadjuvant chemoradiation therapy followed by unsupervised moderate-to-vigorous exercise after therapy, or usual care. Using the theory of planned behavior, we assessed motivation, perceived benefits/harms, and perceived barriers for exercise during and after therapy. Supervised exercise during neoadjuvant chemoradiation therapy was experienced as meaningfully (d≥0.33) more controllable (p=0.08, d=0.60), more enjoyable (p=0.25, d=0.45), and less difficult (p=0.45, d=-0.38) than anticipated. Unsupervised exercise after therapy was experienced as meaningfully more enjoyable (p=0.047, d=0.50) and less difficult (p=0.43, d=-0.36), but also less controllable (p=0.14, d=-0.80) than anticipated. Common self-reported benefits of exercise both during and after neoadjuvant chemoradiation therapy were cardiovascular endurance, physical functioning, and quality of life. Common self-reported harms were exacerbation of treatment side effects. Frequently reported barriers to exercise during therapy were side effects of treatment, whereas exercise barriers after therapy were lack of motivation and lingering side effects.

CONCLUSION

Exercise during and after therapy generally had positive effects on exercise motivation, however, perceived harms and barriers related to treatment side effects were identified.

IMPLICATIONS FOR NURSING PRACTICE

Nurses can help rectal cancer patients initiate and maintain exercise during and after neoadjuvant chemoradiation by discussing the potential benefits, harms, and barriers to exercise.

Effects of exercise during and after neoadjuvant chemoradiation on symptom burden and quality of life in rectal cancer patients: a phase II randomized controlled trial

PURPOSE

We previously demonstrated that exercise during and after neoadjuvant chemoradiation (NACRT) for rectal cancer may improve the rate of pathologic complete/near complete response. Here, we report the effects of exercise on symptom management and quality of life (QoL).

METHODS

Rectal cancer patients (N = 36) were randomized to a supervised high-intensity interval training program during NACRT followed by unsupervised continuous exercise after NACRT or usual care. Patient-reported outcomes were assessed at baseline, post-NACRT, and presurgery including symptom burden (M.D. Anderson Symptom Inventory) and QoL (European Organisation for Research and Treatment of Cancer QLQ- C30 and -CR29).

RESULTS

During NACRT, exercise significantly worsened stool frequency (adjusted between-group difference, 25.8; 95% CI, 4.0 to 47.6; p = 0.022), role functioning (adjusted between-group difference, -21.3; 95% CI, -41.5 to -1.1; p = 0.039), emotional functioning (adjusted between-group difference, -11.7; 95% CI, -22.0 to -1.4; p = 0.028), and cognitive functioning (adjusted between-group difference, -11.6; 95% CI, -19.2 to -4.0; p = 0.004) compared to usual care. After NACRT, exercise significantly worsened diarrhea (adjusted between-group difference, 1.2; 95% CI, 0.1 to 2.3; p = 0.030) and embarrassment (adjusted between-group difference, 19.7; 95% CI, 7.4 to 32.1; p = 0.003) compared to usual care.

CONCLUSIONS

Exercise exacerbated some symptoms and worsened QoL during NACRT; however, most negative effects dissipated after NACRT. Larger trials are necessary to confirm these findings.

IMPLICATIONS FOR CANCER SURVIVORS

If the clinical benefit of exercise is confirmed, then the modest symptom exacerbation during NACRT may be considered tolerable. However, in the absence of any clinical benefit, exercise may be contraindicated in this clinical setting.

Utilization of brachytherapy in Quebec, Canada

BACKGROUND AND PURPOSE

Despite the excellent clinical outcomes from brachytherapy treatments compared with other modalities and the low associated costs, there have been reports of a decline in utilization of brachytherapy. The aim of this study was to investigate in detail the trend in utilization of brachytherapy in the province of Québec, Canada, from 2011 to 2019.

MATERIALS AND METHODS

All radiotherapy clinics in the province of Quebec, and among these the clinics that provide brachytherapy treatments, were identified. This observational retrospective cohort study involved analysis of data compiled by the Ministère de la Santé et des Services Sociaux du Québec for the period of 2011 to end of 2019 on all brachytherapy procedures performed in the province of Quebec. Time series graphs were used to describe the number of high dose rate (HDR) and low dose rate (LDR) brachytherapy treatments during the studied time period. Statistical analysis was conducted using R statistical software.

RESULTS

Between 2011 and 2019, 12 hospitals in the province of Québec provided radiotherapy treatments, and all of them offered brachytherapy services. The median annual number of brachytherapy sessions was 4413 (range 3930-4829). HDR brachytherapy represented over 90% of all brachytherapy treatments throughout the study period. Significant changes over time were observed in the number of treatments: at least 5% change was seen only for the two most common subtypes of brachytherapy, HDR interstitial and HDR intracavitary, with an increase of 9.6% and a decrease of 9.2%, respectively. The use of other subtypes of brachytherapy (HDR-plesiotherapy, LDR-interstitial, LDR-intracavitary, LDR-eye plaque) was stable between 2011 and 2019, with ≤ 2.5% variation.

CONCLUSION

This study demonstrates an overall steady use of brachytherapy between 2011 and 2019 in Quebec. Brachytherapy offers numerous advantages for the treatment of diverse cancer sites. Although more sophisticated external beam radiotherapy treatments have emerged in the last decades, the precision and cost-effectiveness of brachytherapy remain unbeaten. To ensure the continued use and availability of brachytherapy, governments must put in place policies and regulations to that effect. Training and exposure of future health care professionals to brachytherapy within Quebec and Canada is essential to provide all patients the same access to this life saving modality.

Feasibility, Safety, and Preliminary Efficacy of Exercise During and After Neoadjuvant Rectal Cancer Treatment: A Phase II Randomized Controlled Trial

BACKGROUND

Neoadjuvant chemoradiation (NACRT) improves outcomes for patients with rectal cancer; however, there are dose-limiting toxicities and only a 15% to 27% pathologic complete response (pCR) rate. Exercise may help manage toxicities and improve treatment response, but feasibility and early efficacy have not been established. EXERT was a phase II trial designed to establish the feasibility and safety of exercise and provide the first evidence of efficacy.

MATERIALS AND METHODS

Patients with rectal cancer scheduled to receive NACRT were randomly assigned to usual care (n = 18) or exercise (n = 18) involving supervised exercise during NACRT and unsupervised exercise after NACRT. The primary outcome was cardiorespiratory fitness (VO₂ peak). Clinical outcomes included treatment toxicities, treatment completion, and treatment response.

RESULTS

Median attendance at supervised exercise sessions during NACRT was 82%, and median self-reported exercise after NACRT was 90 min/wk. From baseline to post-NACRT, VO₂ peak increased by 0.4 mL·kg^-1·min^-1 in the exercise group and decreased by 0.8 mL·kg^-1·min^-1 in the usual care group (P = .47). There were no significant differences between groups for grade 3/4 toxicities or treatment completion. Of 18 patients in the exercise group, 10 (56%) achieved pCR/near pCR compared with 3 of 17 (18%) in the usual care group (P = .020).

CONCLUSION

Exercise during and after NACRT is feasible for many patients with rectal cancer and may improve pCR despite limited fitness improvements. Larger trials are warranted to confirm if exercise is an effective intervention for improving treatment outcomes in this clinical setting.

Frequent Stools Were Related to Reduced Quality of Life and Capacity in Daily Activities: Weekly Observations During and After Pelvic or Abdominal Radiotherapy

BACKGROUND

Greater knowledge regarding stool frequency and infrequency during pelvic and abdominal irradiation is needed to accurately identify patients at risk of either.

OBJECTIVE

To describe occurrence of frequent and infrequent stools during pelvic-abdominal radiotherapy, and to compare quality of life (QoL) and activities of daily living (ADLs) of those patients experiencing frequent stools with those of patients experiencing infrequent stools.

METHODS

Longitudinally during radiotherapy, 193 patients (64% had gynecological tumors) documented stool frequency, medications, and QoL using the Functional Assessment of Cancer Therapy-General.

RESULTS

Fifty (26%) experienced frequent stools (≥28 stools a week), and 17 (9%) experienced infrequent stools (<3 stools a week). The frequency of stools and the consumption of medication for diarrhea were highest the last week of the radiotherapy period (50% had ≥49 stools a week, and 50% could not even define the number of stools). Thirty-seven of the patients experiencing frequent stools used antidiarrhea medications. Patients with frequent stools experienced lower QoL (P = .035) and capacity in ADLs (P = .023) compared with patients not experiencing frequent stools.

CONCLUSIONS

A fourth of patients irradiated over pelvic or abdominal fields experienced frequent stools, defined as moderate to severe diarrhea, and those patients experienced lower QoL and capacity in ADLs compared with patients who did not experience frequent stools. Infrequent stools were rarely experienced.

IMPLICATIONS FOR PRACTICE

Cancer nursing professionals should deliver evidence-based strategies to prevent frequent stools and treat frequent stools as an approach to lower the risk of impaired capacity in daily living and worsened QoL.

Association of Radiotherapy-Related Intestinal Injury and Cancer-related Fatigue: A Brief Review and Commentary

Radiotherapy treatment-induced intestinal injury and gut microbial perturbation/dysbiosis have been implicated in the pathobiology of cancer-related fatigue. The objective of this brief review was to explore the available evidence of the relationship between intestinal injury and self-reported fatigue, especially among cancer patients. The scientific evidence-including our own-linking gut mucosal barrier dysfunction and gut microbial perturbation/dysbiosis induced by cancer treatment with worsening of cancer related fatigue (perhaps through the gut-brain axis) is limited but promising. Emerging data suggest that lifestyle interventions and the administration of specific probiotics may favorably modulate the gut microbiota and potentially mediate beneficial effects leading to improvements in fatigue.

Co-Occurrence of Symptoms and Gut Microbiota Composition Before Neoadjuvant Chemotherapy and Radiation Therapy for Rectal Cancer: A Proof of Concept

PURPOSE

To examine a) whether there are significant differences in gut microbial diversity and in the abundance of gut microbial taxa; and b) differences in predicted functional pathways of the gut microbiome between those participants with high co-occurring symptoms and those with low co-occurring symptoms, prior to neoadjuvant chemotherapy and radiation therapy (CRT) for rectal cancer.

METHODS

Rectal cancer patients (n = 41) provided stool samples for 16 S rRNA gene sequencing and symptom ratings for fatigue, sleep disturbance, and depressive symptoms prior to CRT. Descriptive statistics were computed for symptoms. Gut microbiome data were analyzed using QIIME2, LEfSe, and the R statistical package.

RESULTS

Participants with high co-occurring symptoms (n = 19) had significantly higher bacterial abundances of Ezakiella, Clostridium sensu stricto, Porphyromonas, Barnesiella, Coriobacteriales Incertae Sedis, Synergistiaceae, Echerichia-Shigella, and Turicibacter compared to those with low co-occurring symptoms before CRT (n = 22). Biosynthesis pathways for lipopolysaccharide, L-tryptophan, and colanic acid building blocks were enriched in participants with high co-occurring symptoms. Participants with low co-occurring symptoms showed enriched abundances of Enterococcus and Lachnospiraceae, as well as pathways for β-D-glucoronosides, hexuronide/hexuronate, and nicotinate degradation, methanogenesis, and L-lysine biosynthesis.

CONCLUSION

A number of bacterial taxa and predicted functional pathways were differentially abundant in patients with high co-occurring symptoms compared to those with low co-occurring symptoms before CRT for rectal cancer. Detailed examination of bacterial taxa and pathways mediating co-occurring symptoms is warranted.

Association Between Preoperative Patient-Reported Symptoms and Postoperative Outcomes in Rectal Cancer Patients: A Retrospective Cohort Study

BACKGROUND

Rectal cancer patients undergoing preoperative radiotherapy experience a significant symptom burden. However, it is unknown whether symptoms during radiotherapy may portend adverse postoperative outcomes and healthcare utilization.

METHODS

A retrospective cohort study was performed of rectal cancer patients undergoing neoadjuvant radiotherapy and proctectomy in Ontario from 2007 to 2014. The primary outcome was a complicated postoperative course-a dichotomous variable created as a composite of postoperative mortality, major morbidity, or hospital readmission. Patient-reported Edmonton Symptom Assessment System (ESAS) scores, collected routinely at outpatient provincial cancer center visits, were linked to administrative healthcare databases. The receiver-operating characteristic analysis was used to compare ESAS scoring approaches and to stratify patients into low versus high symptom score groups. Multivariable regression models were constructed to evaluate associations between preoperative symptom scores and postoperative outcomes.

RESULTS

1455 rectal cancer patients underwent sequential radiotherapy and proctectomy during the study period and recorded symptom assessments. Patients with high preoperative symptom scores were significantly more likely to experience a complicated postoperative course (OR 1.55, 95% CI 1.23-1.95). High preoperative ESAS scores were also associated with the secondary outcomes of emergency department visits (OR 1.34, 95% CI 1.08-1.66) and longer length of stay (IRR 1.23, 95% CI 1.04-1.45).

CONCLUSIONS

Rectal cancer patients reporting elevated symptom scores during neoadjuvant radiotherapy have increased odds of experiencing a complicated postoperative course. Preoperative patient-reported outcome screening may be a useful tool to identify at-risk patients and to efficiently direct perioperative supportive care.

Methodology Aspects of Nausea Measuring During Pelvic Radiotherapy: Daily Nausea Measuring Is Successful to Identify Patients Experiencing Nausea

BACKGROUND

Nausea seems underreported during pelvic radiotherapy.

OBJECTIVE

The aims of this study were to investigate if a 5-week recall measure of nausea covering the entire radiotherapy period was comparable with accumulated daily nausea measurements and to investigate if the measuring method affected potential difference in quality of life (QoL) between nauseated patients and patients free from nausea.

METHODS

This longitudinal methodology study covered 200 patients (mean age, 64 years; 84% women; 69% had gynecological cancer). The patients graded QoL (Functional Assessment of Cancer Therapy-General). They registered nausea daily and at a 5-week recall at the end of radiotherapy.

RESULTS

The nausea-intensity category scale and visual analog scale correlated well (Spearman correlation coefficient = 0.622). According to the 5-week recall, 57 of 157 answering patients (36%) experienced nausea during the radiotherapy period. Using the daily nausea measurements, 94 of 157 patients (60%) experienced nausea (relative risk, 1.65; 95% confidence interval, 1.29-2.10). Of these 94 nauseated patients, 39 (42%) did not report nausea using the 5-week recall. The nauseated patients experienced worse QoL (physical/functional subscores) than patients free from nausea whether nausea was registered daily or at the 5-week recall.

CONCLUSIONS

Almost half, 42%, of the patients who experienced nausea according to daily nausea measurements did not report having had nausea according to the 5-week recall. Nauseated patients graded worse QoL than patients who were free from nausea.

IMPLICATIONS FOR PRACTICE

Nursing professionals should measure nausea repeatedly to identify patients at risk of nausea and worsened QoL, to be able to deliver evidence-based antiemetic treatment strategies.

Model-Based Dose Calculation Algorithms for Brachytherapy Dosimetry

The purpose of this study was to review the limitations of dose calculation formalisms for photon-emitting brachytherapy sources based on the American Association of Physicists in Medicine (AAPM) Task Group No. 43 (TG-43) report and to provide recommendations to transition to model-based dose calculation algorithms. Additionally, an overview of these algorithms and approaches is presented. The influence of tissue and seed/applicator heterogeneities on brachytherapy dose distributions for breast, gynecologic, head and neck, rectum, and prostate cancers as well as eye plaques and electronic brachytherapy treatments were investigated by comparing dose calculations based on the TG-43 formalism and model-based dose calculation algorithms.

[Time perspective and quality of life in rectal cancer patients: An exploratory study]

The impact of rectal cancer on patient quality of life has been investigated but no research has yet examined the impact of time perspective in the assessment of quality of life of rectal cancer patients. Our goal is to explore the links between quality of life and time perspective and the role of time perspective as a determinant of quality of life. Data were collected from 69 patients who completed a questionnaire comprising a specific measure of quality of life (FACT-C), a measure of time perspective (ZTPI), a measure of emotional distress (HADS) and a collection of socio-demographic and medical data. Regression analyses revealed that present fatalist, past positive and future time perspective predicted quality of life. Present fatalist time perspective seemed to have a deleterious impact on specific measure of rectal cancer quality of life. Present fatalist and future time perspective predicted a better emotional quality of life whereas past positive predicted a worse emotional quality of life. These results suggest the importance of considering time perspective as a determinant of psychological quality of life in order to improve the QoL of patients.

Exploring Gender-Related Experiences of Cancer Survivors Through Creative Arts: A Scoping Review

Negative health consequences of cancer and its treatments are multifaceted. Research suggests numerous psychosocial benefits may be gained by cancer survivors who engage in arts-based practices. To grasp the breadth of this literature, we undertook a scoping review exploring the intersection between arts-based practices, gender, and cancer. Three databases were searched according to the following criteria: (a) participants older than 18 years, (b) use of arts-based practices, (c) explore cancer survivorship, and (d) gender-based analysis component. A total of 1,109 studies were identified and 11 met inclusion criteria. Themes extracted illustrate four transformative moments related to gender identities postcancer diagnosis: (a) fostering reflection after a cancer diagnosis, (b) constructing new narratives of gender postcancer, (c) navigating gender norms in search of support for new identities, and (d) interrogation of perceived gender norms. Findings demonstrate potential contributions of arts-based practices in shaping cancer-related gender identities. Future research should investigate these experiences across a wider population.

Exercise during and after neoadjuvant rectal cancer treatment (the EXERT trial): study protocol for a randomized controlled trial

Background

Standard treatment for locally advanced rectal cancer includes 5–6 weeks of neoadjuvant chemoradiotherapy (NACRT) followed by total mesorectal excision 6–8 weeks later. NACRT improves local disease control and surgical outcomes but also causes side effects including fatigue, diarrhea, hand-foot syndrome, and physical deconditioning that may impede quality of life (QoL), treatment completion, treatment response, and long-term prognosis. Interventions to improve treatment outcomes and manage side effects that are safe, tolerable and low-cost are highly desirable. Exercise has been shown to improve some of these outcomes in other cancer patient groups but no study to date has examined the potential benefits (and harms) of exercise training during and after NACRT for rectal cancer.

Methods/design

The Exercise During and After Neoadjuvant Rectal Cancer Treatment (EXERT) trial is a single-center, prospective, two-armed, phase II randomized controlled trial designed to test the preliminary efficacy of exercise training in this clinical setting and to further evaluate its feasibility and safety. Participants will be 60 rectal cancer patients scheduled to receive long-course NACRT followed by total mesorectal excision. Participants will be randomly assigned to exercise training or usual care. Participants in the exercise training group will be asked to complete three supervised, high-intensity interval training sessions/week during NACRT and ≥ 150 min/week of unsupervised, moderate-to-vigorous-intensity, continuous exercise training after NACRT prior to surgery. Participants in the usual care group will be asked not to increase their exercise from baseline. Assessments will be completed pre NACRT, post NACRT, and pre surgery. The primary endpoint will be cardiorespiratory fitness (VO₂ peak) at the post-NACRT time point assessed by a graded exercise test. Secondary endpoints will include functional fitness assessed by the Senior’s Fitness Test, QoL assessed by the European Organisation of Research and Treatment of Cancer, and symptom management assessed by the M.D. Anderson Symptom Inventory. Exploratory clinical endpoints will include treatment toxicities, treatment completion, treatment response, and surgical complications.

Discussion

If the preliminary findings of EXERT are positive, additional research will be warranted to confirm whether exercise is an innovative treatment to maintain QoL, manage side effects, and/or improve treatment outcomes in rectal cancer patients.

The short-term impact of colorectal cancer treatment on physical activity, functional status and quality of life: a systematic review

BACKGROUND

Physical activity, functional status and quality of life (QoL) are important determinants of the quality of life (QoL) after colorectal cancer (CRC) treatment; however, little is known on how the treatment impacts these outcomes. Having this understanding could help clinicians develop and implement strategies that would enhance or maintain the QoL of CRC patients.

OBJECTIVES

To identify the impact of curative CRC treatment (surgery with or without radiotherapy and/or chemotherapy) on physical activity, functional status and QoL within one year of treatment or diagnosis.

INCLUSION CRITERIA TYPES OF PARTICIPANTS

Colorectal cancer survivors aged 18 years and over.

TYPES OF INTERVENTIONS

Curative CRC treatment, which was surgery with or without radiotherapy and/or chemotherapy.

TYPES OF STUDIES

Pre- and post-observational and experimental studies.

OUTCOMES

Physical activity, ability to perform activities of daily living (functional status) and QoL.

SEARCH STRATEGY

CINAHL, Embase, MEDLINE, OpenGrey and ProQuest Dissertations and Theses were used to obtain published and unpublished studies in English. The date range was the start of indexing to February 2015.

METHODOLOGICAL QUALITY

All studies were assessed independently by two reviewers for relevance, eligibility and methodological quality.

DATA EXTRACTION

Data from included papers were extracted using a modified data extraction tool. Data that were presented graphically were extracted using online software.

DATA SYNTHESIS

The differences between postoperative and baseline values were calculated using the Review Manager 5.3.5 (Copenhagen: The Nordic Cochrane Centre, Cochrane) calculator and expressed as mean difference and their corresponding 95% confidence interval. Where possible, study results were pooled in statistical meta-analysis. The physical activity, functional status and some QoL results are presented in a narrative and table form.

RESULTS

A total of 23 studies were included in this review: two studies (N = 2019 patients) evaluated physical activity, two studies (N = 6908 patients) assessed functional status and 22 studies (N = 2890 patients) measured QoL. Physical activity was observed to decrease at six months after treatment. The functional status of CRC patients decreased, particularly in the elderly (Summary of findings 1 and 2). As for QoL, only the physical and functional aspects were seen to decline up to six months, but scores almost returned to baseline levels at one year after treatment. The QoL studies that used the European Organization for Research and Treatment of Cancer QLQ-C30 tool were pooled in statistical meta-analysis and summarized in Summary of findings 2. The results must be interpreted carefully due to the heterogeneity of studies and scarcity of recent studies.

CONCLUSION

In spite of the limitations, it is likely that the physical and functional capacity of CRC survivors deteriorates after treatment.

IMPLICATIONS FOR PRACTICE

The period between diagnosis and treatment provides an opportunity for clinicians to implement interventions (e.g. exercise interventions) that could enhance or restore the physical and functional capacity of CRC survivors.

IMPLICATIONS FOR RESEARCH

The paucity of studies and heterogeneity need to be addressed. The outcomes for colon and rectal cancer survivors, ostomates and non-ostomates must be analyzed separately.

Nursing implications: symptom presentation and quality of life in rectal cancer patients

AIMS AND OBJECTIVES

To determine the changes in symptoms experienced by rectal cancer patients during preoperative chemoradiotherapy, with a specific focus on fatigue and to explore how symptoms impact the quality of life.

BACKGROUND

Rectal cancer continues to be a healthcare issue internationally, despite advances in management strategies, which includes the administration of preoperative chemoradiotherapy to improve locoregional control. It is known that this treatment may cause adverse effects; however, there is a paucity of literature that specifically examines fatigue, symptoms and quality of life in this patient cohort.

DESIGN

A prospective, quantitative correlational design using purposive sampling was adopted.

METHODS

Symptoms and quality of life were measured with validated questionnaires in 35 patients at four time points.

RESULTS

Symptoms that changed significantly over time as examined using rm-anova include fatigue, bowel function issues, nutritional issues, pain, dermatological issues and urinary function issues. Findings indicate that fatigue leads to poorer quality of life, with constipation, bloating, stool frequency, appetite loss, weight worry, nausea and vomiting, dry mouth and pain also identified as influencing factors on quality of life.

CONCLUSION

Findings have highlighted the importance of thorough symptom assessment and management of patients receiving preoperative chemoradiotherapy, particularly midway through treatment, in order to optimise quality of life and minimise interruptions to treatment.

RELEVANCE TO CLINICAL PRACTICE

Close monitoring of symptoms during preoperative chemoradiotherapy, particularly at week 4, will enable the implementation of timely interventions so that interruptions to treatment are prevented and the quality of life is optimised, which may hasten postoperative recovery times.

Predicting radiotherapy-related clinical toxicities in cancer: a literature review

Assessment of patients receiving radiotherapy for cancer is essential, with the ability to identify those who may be more likely to experience radiotherapy-related side effects noted as an important issue for nurses. Body mass, age, and radiation dose may be predictive factors for the development of such side effects. This review considers these factors and how nurses can use this evidence to inform their care, with results indicating that the dose of radiation, the site treated, and body mass index are predictive of toxicities that may develop. Increased awareness of these predictive factors will aid nurses in identifying patients at greater risk of developing radiation-related side effects. This will assist in guiding nursing interventions, as well as enabling the individualization of patient education, by placing greater emphasis on preventive measures for patients who are more vulnerable to the development of radiation-related toxicities.
