Quality of Life assessment through the EORTC questionnaires of locally advanced rectal cancer patients treated with preoperative chemo-radiotherapy

A Prospective Study Evaluating Health-Related Quality of Life Following a Multimodal Treatment for Colorectal Cancer

PURPOSE

The major improvements in the diagnosis and treatment of colorectal cancer (CRC) over the past decades increased the patients' survival rates. Despite this, patients and clinicians still need to address the long-term physical and psychosocial effects over time. This paper aims to prospectively assess CRC patients' HR-QoL psychological distress and sexual functioning and identify clinical, demographic, and psychological predictors.

METHODS

In total, 55 patients were evaluated from diagnosis to 5-year follow-up with the following instruments: EORTC QLQ-C30 and QLQ-C38 for QoL and sexuality; HADS for psychological distress; and specific questions to detect psychological variables.

RESULTS

QoL worsened after diagnosis and returned to baseline values after 5 years. Sexual function significantly deteriorated over time (with no recovery, especially in women), while borderline/severe anxiety and depression decreased. A better HR-QoL at baseline was associated with better physical, social and sexual functioning, positive body image and sexual pleasure after 5 years.

CONCLUSION

HR-QoL allows the early detection of patients at risk, favoring prompt patient-centered interventions.

Systematic Review of Cognitive Impairment in Colorectal Cancer Survivors Who Received Chemotherapy

PROBLEM IDENTIFICATION

Cognitive impairment is a common and troublesome side effect experienced by many cancer survivors. It can have a significant impact on survivors' ability to function and enjoy a high quality of life. However, most cognitive impairment research has focused on breast cancer survivors, despite the high rates of colorectal cancer and the toxicity of treatment agents in some colorectal cancer chemotherapeutic regimens, which have been linked to cognitive impairment. This review provides a novel synthesis of what is known about cognitive impairment in colorectal cancer survivors.

LITERATURE SEARCH

CINAHL®, Cochrane Library, Embase®, PsycINFO®, and PubMed® were systematically searched by a health sciences librarian.

DATA EVALUATION

Data were extracted across studies; findings about the prevalence, severity, and correlates of cognitive impairment were synthesized.

SYNTHESIS

Across findings from 26 articles representing 24 independent studies, 13%-57% of participants had cognitive impairment. Potential demographic, physiologic, and psychological correlates of cognitive impairment were identified.

IMPLICATIONS FOR PRACTICE

Findings indicate a need to focus research and patient assessments on early identification of risk factors, assessing for existing cognitive deficits and testing interventions to decrease cognitive impairment in colorectal cancer survivors.

Non-inferiority multicenter prospective randomized controlled study of rectal cancer T2-T3s (superficial) N0, M0 undergoing neoadjuvant treatment and local excision (TEM) vs total mesorectal excision (TME)

PURPOSE

The standard treatment of rectal adenocarcinoma is total mesorectal excision (TME), in many cases requires a temporary or permanent stoma. TME is associated with high morbidity and genitourinary alterations. Transanal endoscopic microsurgery (TEM) allows access to tumors up to 20 cm from the anal verge, achieves minimal postoperative morbidity and mortality rates, and does not require an ostomy. The treatment of T2, N0, and M0 cancers remains controversial. Preoperative chemoradiotherapy (CRT) in association with TEM reduces local recurrence and increases survival. The TAU-TEM study aims to demonstrate the non-inferiority of the oncological outcomes and the improvement in morbidity and quality of life achieved with TEM compared with TME.

METHODS

Prospective, multicenter, randomized controlled non-inferiority trial includes patients with rectal adenocarcinoma less than 10 cm from the anal verge and up to 4 cm in size, staged as T2 or T3-superficial N0-M0. Patients will be randomized to two areas: CRT plus TEM or radical surgery (TME). Postoperative morbidity and mortality will be recorded and patients will complete the quality of life questionnaires before the start of treatment, after CRT in the CRT/TEM arm, and 6 months after surgery in both arms. The estimated sample size for the study is 173 patients. Patients will attend follow-up controls for local and systemic relapse.

CONCLUSIONS

This study aims to demonstrate the preservation of the rectum after preoperative CRT and TEM in rectal cancer stages T2-3s, N0, M0 and to determine the ability of this strategy to avoid the need for radical surgery (TME).

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.

Validation of the Danish version of the disease specific instrument EORTC QLQ-CR38 to assess health-related quality of life in patients with colorectal cancer

Background

The European Organisation for Research and Treatment of Cancer (EORTC) quality of life colorectal questionnaire module (QLQ-CR38) was developed in 1999, and an update, the QLQ CR29 was published recently. To date the Danish version of the questionnaire has not been validated. The aim of this study was to examine the psychometric properties of the Danish version of EORTC QLQ-CR38.

Methods

EORTC QLQ-CR38 was administered to 190 patients with colorectal cancer in two Danish hospitals, one month after their operation. A psychometric evaluation of the questionnaire’s structure, reliability, convergent, divergent and known-groups validity was performed.

Results

Data from 164 (86.3%) patients were available for analysis. The Danish version of EORTC QLQ-CR38 showed satisfactory psychometric properties for the scales: body image, sexual functioning, male sexual problems and defecations problems. Suboptimal psychometric performances were found for the scales: micturition problems, symptoms of the gastrointestinal tract and weight loss. Evaluation of the psychometric properties of the scale chemotherapy side effects was limited by the low number of patients receiving chemotherapy. It was not possible to assess the psychometric properties of the scale female sexual problems and the single item sexual enjoyment due to a high number of missing values. The homogeneity of the study population made the evaluation of known-group validity difficult.

Conclusions

The results of this study suggest that the validity of the Danish version of EORTC QLQ-CR38 is acceptable. Furthermore, the results support the appropriateness of the updated version, the EORTC QLQ-CR29.

Demographics, cancer-related factors, and sexual function in rectal cancer patients in Taiwan: preliminary findings

BACKGROUND

Sexual function has been ignored because survival issues associated with cancer treatment commonly take precedence over sexual issues. Sexual dysfunction remains a recognized complication after cancer treatment despite improvement in survival rates for patients with rectal cancer.

OBJECTIVE

This study investigated the relationships among demographics (ie, age, gender, education, religion) and cancer-related factors (ie, stage of disease, type of treatment, time since operation, comorbid conditions) and sexual function in patients with rectal cancer.

METHODS

A cross-sectional study with a convenience sample of 120 rectal cancer patients from a medical center in southern Taiwan completed the International Index of Erectile Function, Female Sexual Function Index, a demographic questionnaire, and medical data during face-to-face interviews.

RESULTS

In both men and women, better sexual function was significantly associated with younger age but not with religion, time since operation, or number of chronic conditions. In men only, better sexual function was associated with earlier stage of cancer, fewer cancer treatments, and higher education.

CONCLUSION

Sexual function may receive greater attention in Taiwan when rectal cancer patients receive appropriate care. A larger diverse sample is needed for further examination of sexual function over time.

IMPLICATIONS FOR PRACTICE

Health promotion programs for long-term survivors should include a consistent assessment of sexual function before and after an operation, and patients should receive clinical sexual counseling.

Sexual (dys)function and the quality of sexual life in patients with colorectal cancer: a systematic review

BACKGROUND

To determine (i) the prevalence of sexual (dys)function in patients with colorectal cancer and (ii) treatment-related and sociodemographic aspects in relation to sexual (dys)function and the quality of sexual life. Recommendations for future studies are provided.

METHODS

A systematic search was conducted during the period 1990 to July 2010 that used the databases PubMed, PsychINFO, The Cochrane Library, EMBASE, and OVID Medline.

RESULTS

Eighty-two studies were included. The mean quality score was 7.2. The percentage of preoperatively potent men that experienced sexual dysfunction postoperatively varied from 5% to 88%. Approximately half of the women reported sexual dysfunction. Preoperative radiotherapy, a stoma, complications during or after surgery, and a higher age predicted more sexual dysfunction with a strong level of evidence. Type of surgery and a lower tumor location predicted more sexual dysfunction with a moderate level of evidence. Insufficient evidence existed for predictors of the quality of sexual life. Current studies mainly focus on biological aspects of sexual (dys)function. Furthermore, existing studies suffer from methodological shortcomings such as a cross-sectional design, a small sample size, and the use of nonstandardized measurements.

CONCLUSION

Sexuality should be investigated prospectively from a biopsychosocial model, hereby including the quality of sexual life.

Fatigue and other variables during adjuvant chemotherapy for colon and rectal cancer

PURPOSE/OBJECTIVES

To examine patterns of fatigue and other variables (sleep quality, sleep-wake variables, activity and rest, circadian rhythms, quality of life [QOL], blood counts, and demographic and medical variables) during colon and rectal cancer adjuvant chemotherapy, as well as feasibility of the study.

DESIGN

Longitudinal, descriptive feasibility study.

SETTING

Two oncology clinics in the midwestern region of the United States.

SAMPLE

From April 2006-December 2008, 27% of screened subjects (n = 21) enrolled and 14 completed the study. Participants were middle aged, partnered, and employed and had postsecondary education.

METHODS

Measurements completed during the first week of three two-week cycles (chemotherapy 1-3) and at six weeks (before chemotherapy 4) were the Piper Fatigue Scale, Pittsburgh Sleep Quality Index, wrist actigraphy, Functional Assessment of Cancer Therapy-Colon, blood counts, and demographic and medical data form. Analysis included descriptive statistics and repeated-measures analysis of variance.

MAIN RESEARCH VARIABLES

Fatigue, sleep quality, sleep-wake variables, activity-rest, circadian activity rhythms, and QOL.

FINDINGS

Fatigue was mild at baseline and rose to moderate levels during chemotherapy 1-3. Sleep quality was poor the months prior to chemotherapy 1 and chemotherapy 4. Actigraphy data revealed disturbed sleep, low daytime activity, and impaired circadian activity rhythms during the first week after chemotherapy 1-3. QOL ratings were similar to those in other cancer populations. Fatigue increased, and white blood cell counts decreased significantly over time.

CONCLUSIONS

During adjuvant chemotherapy, patients reported moderate fatigue and poor sleep quality; actigraphs confirmed problems with sleep maintenance as well as low daytime activity and disturbed circadian rhythms. Multiple barriers were encountered during the study.

IMPLICATIONS FOR NURSING

Clinicians should screen for fatigue and sleep-wake variables and use guidelines to select interventions.

The EORTC Quality of Life Questionnaire for patients with prostate cancer: EORTC QLQ-PR25. Validation study for Spanish patients

OBJECTIVES

The EORTC Quality of Life (QL) Group has developed a questionnaire, the EORTC QLQ-PR25, for evaluating QL in prostate cancer. The aim of this study is to assess the psychometric properties of the EORTC QLQPR25 when applied to a sample of Spanish patients.

MATERIALS AND METHODS

One hundred and thirty-seven prostate cancer patients with localised disease who started radiotherapy with radical intention combined with or without hormonotherapy prospectively completed the EORTC QLQ-C30 and EORTC QLQ-PR25 questionnaires three times: on the first and last day of radiotherapy and in the follow-up period. Psychometric evaluation of the questionnaires' structure, reliability and validity was conducted.

RESULTS

Multitrait scaling analysis showed that many of the item-scale correlation coefficients met the standards of convergent and discriminant validity. Exceptions appeared mainly in the scales for bowel symptoms and for hormonal- treatment-related symptoms. Cronbach's coefficients of the scales were good (0.72-0.86) for the urinary symptoms and sexual function scales but they were lower (<0.70) for the bowel and hormonal treatment scales. Most scales of the EORTC QLQ-PR25 had low to moderate intercorrelations. Correlations between the scales of the QLQ-C30 and the module were generally low. Group comparison analyses showed better QL in patients with higher Performance Status. Changes in QL appeared throughout the measurements. These were in line with the treatment process.

CONCLUSIONS

The EORTC QLQ-PR25 was a reliable and valid instrument when applied to a sample of Spanish prostate cancer patients. These results are in line with those of the EORTC validation study.

Surgery-predominant combined treatment for colorectal cancer

Colorectal cancer (CRC) is the third most common cancer and the fifth leading cause of cancer-related mortality in China with an increasing trend, which is emphasizing the need for improvements in therapeutic options. The 5-year survival rate of surgery, the first-line treatment for CRC, is just about 50 percent. In recent years many patients with CRC have benefited from the combined treatment with surgery for CRC, which integrates chemotherapy, radiotherapy, concurrent chemoradiotherapy, biotherapy, traditional Chinese medicine, etc., especially patients at advanced stage. This paper highlighted current situation for combined treatment with surgery for CRC.
