Quality of Life in patients with resected oesophageal cancer

Characteristics Predicting Short-Term and Long-Term Health-Related Quality of Life in Patients with Esophageal Cancer After Neoadjuvant Chemoradiotherapy and Esophagectomy

BACKGROUND

Esophagectomy is associated with lasting effect on health-related quality of life (HRQOL). Patients desire detailed information on the expected impact of treatment on their postoperative HRQOL. The aim of the present study is to identify clinicopathological characteristics predictive for changes in short-term and long-term HRQOL after neoadjuvant chemoradiotherapy (nCRT) and surgery.

METHODS

HRQOL was measured using EORTC-QLQ-C30 and QLQ-OES24 questionnaires prior to nCRT, three, six, nine and twelve months postoperatively and at a minimum of six years postoperatively. Based on previous experience and available literature, several subgroups were predefined for different clinicopathological characteristics: baseline global HRQOL, WHO performance status, histology, tumor stage and tumor location. The primary endpoints of the present study were the change compared to baseline in the HRQOL dimensions physical functioning and eating problems. Secondary endpoints were global HRQOL, fatigue and emotional problems.

RESULTS

In total, 134 (76%) of 177 patients who received HRQOL questionnaires, responded at baseline. Patients who reported a high baseline global HRQOL had a more severe deterioration in eating problems (+14.5 to + 18.0), global HRQOL (-16.0 to -28.0) and fatigue (+10.5 to +14.9) up to six years postoperatively compared to patients who reported a low baseline global HRQOL. Patients who had stage 2 tumor (UICC 6th edition) had a more severe deterioration in eating problems (+14.6 to +19.0) and global HRQOL (-10.1 to -17.1) than patients who had stage 3 tumor.

CONCLUSIONS

The results suggest that patients with locally advanced esophageal cancer in favorable condition at baseline decline more in terms of various HRQOL outcomes.

Quality of Life after Open or Minimally Invasive Esophagectomy in Patients With Esophageal Cancer-A Systematic Review

Although esophageal cancer is rare in the United States, 5-year survival and quality of life (QoL) are poor following esophageal cancer surgery. Although esophageal cancer has been surgically treated with esophagectomy through thoracotomy, an open procedure, minimally invasive surgical procedures have been recently introduced to decrease the risk of complications and improve QoL after surgery. The current study is a systematic review of the published literature to assess differences in QoL after traditional (open) or minimally invasive esophagectomy. We hypothesized that QoL is consistently better in patients treated with minimally invasive surgery than in those treated with a more traditional and invasive approach. Although global health, social function, and emotional function improved more commonly after minimally invasive surgery compared with open surgery, physical function and role function, as well as symptoms including choking, dysphagia, eating problems, and trouble swallowing saliva, declined for both surgery types. Cognitive function was equivocal across both groups. The potential small benefits in global and mental health status among those who experience minimally invasive surgery should be considered with caution given the possibility of publication and selection bias.

Patient-reported outcome measures in dysphagia: a systematic review of instrument development and validation

OBJECTIVE

Patient-reported outcome (PRO) measures are commonly used to capture patient experience with dysphagia and to evaluate treatment effectiveness. Inappropriate application can lead to distorted results in clinical studies. A systematic review of the literature on dysphagia-related PRO measures was performed to (1) identify all currently available measures and (2) to evaluate each for the presence of important measurement properties that would affect their applicability.

DESIGN

MEDLINE via the PubMed interface, the Cumulative Index of Nursing and Allied Health Literature, and the Health and Psychosocial Instrument database were searched using relevant vocabulary terms and key terms related to PRO measures and dysphagia. Three independent investigators performed abstract and full text reviews. Each study meeting criteria was evaluated using an 18-item checklist developed a priori that assessed multiple domains: (1) conceptual model, (2) content validity, (3) reliability, (4) construct validity, (6) scoring and interpretation, and (7) burden and presentation.

RESULTS

Of 4950 abstracts reviewed, a total of 34 dysphagia-related PRO measures (publication year 1987-2014) met criteria for extraction and analysis. Several PRO measures were of high quality (MADS for achalasia, SWAL-QOL and SSQ for oropharyngeal dysphagia, PROMIS-GI for general dysphagia, EORTC-QLQ-OG25 for esophageal cancer, ROMP-swallowing for Parkinson's Disease, DSQ-EoE for eosinophilic esophagitis, and SOAL for total laryngectomy-related dysphagia). In all, 17 met at least one criterion per domain. Thematic deficiencies in current measures were evident including: (1) direct patient involvement in content development, (2) empirically justified dimensionality, (3) demonstrable responsiveness to change, (4) plan for interpreting missing responses, and (5) literacy level assessment.

CONCLUSION

This is the first comprehensive systematic review assessing developmental properties of all available dysphagia-related PRO measures. We identified several instruments with robust measurement properties in multiple diseases including achalasia, oropharyngeal dysphagia, post-surgical dysphagia, esophageal cancer, and dysphagia related to neurological diseases. Findings herein can assist clinicians and researchers in making more informed decisions in selecting the most fundamentally sound PRO measure for a given clinical, research, or quality initiative.

Does neoadjuvant treatment before oncologic esophagectomy affect the postoperative quality of life? A prospective, longitudinal outcome study

To evaluate the cancer patients' quality of life (QoL) following esophagectomy the focus was placed on the impact of neoadjuvant treatment before surgery. For patients undergoing oncologic surgery, the QoL is generally accepted as an important outcome parameter in addition to clinical parameters. This prospective nonrandomized study evaluated QoL in patients treated by preoperative chemo(radio)therapy followed by either surgery or surgery alone with special focus on the postoperative course. QoL was assessed in 131 consecutive patients who underwent surgery for esophageal cancer. The EORTC-QLQ-C30 and a tumor-specific module were administered before surgery, at discharge, 3, 6, 12, and 24 months after surgery. Clinical data were collected prospectively and a follow up was performed every 6 months. The histological type of cancer was squamous cell carcinoma in 49.6% and adenocarcinoma in 50.4%. There was no significant difference between patients that were treated neoadjuvantly and those that were first operated on with regard to morbidity, mortality, and survival rates (5-year survival rate of 34%). Most QoL scores dropped significantly below the baseline in the early postoperative period and recovered slowly during the follow-up period to almost preoperative levels in many scores. There was no statistically significant difference in any of the QoL scales between neoadjuvantly treated or primary operated patients. Esophageal resections are associated with significant deterioration of QoL, which slowly recovers during the follow-up period to an almost preoperative level. Neoadjuvant treatment seems to not further negatively affect the QoL deterioration.

Comparison of the health-related quality of life in patients with narrow gastric tube and whole stomach reconstruction after oncologic esophagectomy: a prospective randomized study

BACKGROUND AND AIMS

To compare the health-related quality of life in patients with narrow gastric tube and whole stomach reconstructions after oncologic esophagectomy.

MATERIAL AND METHODS

In a prospective randomized single-center study from 2007 to 2008, 104 patients underwent esophagectomy for cancer. To assess health-related quality of life, the questionnaire (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and the Oesophagus-Specific Quality of Life Questionnaire 18) was administered at 3 weeks, 6 months, 1 year, and 2 years after surgery.

RESULTS

The perioperative complication rate was 26.9% in narrow gastric tube group and 48.1% in whole stomach group (P = 0.31). At the time of 3 weeks after surgery, the reflux and dyspnea scores were higher in whole stomach group than in narrow gastric tube group, which meant that the patients in whole stomach group suffered more severe problem. At the time of 6 months and 1 year after surgery, the reflux scores were lower in narrow gastric tube group than in whole stomach group, which revealed that there were less problems of reflux in the patients of narrow gastric tube group; meanwhile, the score of physical function scale in narrow gastric tube group was higher conversely, which suggested that the patients gain a better status in physical function. Nausea and vomiting is the only notable symptom that was worse in whole stomach group at the time of 2 years after surgery, which suggested that patients in whole stomach group suffered more severe nausea and vomiting.

CONCLUSIONS

Narrow gastric tube reconstruction may be a good alternative choice for patients undergoing oncologic esophagectomy in view of better health-related quality of life after the surgery.

Developing core outcomes sets: methods for identifying and including patient-reported outcomes (PROs)

BACKGROUND

Synthesis of patient-reported outcome (PRO) data is hindered by the range of available PRO measures (PROMs) composed of multiple scales and single items with differing terminology and content. The use of core outcome sets, an agreed minimum set of outcomes to be measured and reported in all trials of a specific condition, may improve this issue but methods to select core PRO domains from the many available PROMs are lacking. This study examines existing PROMs and describes methods to identify health domains to inform the development of a core outcome set, illustrated with an example.

METHODS

Systematic literature searches identified validated PROMs from studies evaluating radical treatment for oesophageal cancer. PROM scale/single item names were recorded verbatim and the frequency of similar names/scales documented. PROM contents (scale components/single items) were examined for conceptual meaning by an expert clinician and methodologist and categorised into health domains. A patient advocate independently checked this categorisation.

RESULTS

Searches identified 21 generic and disease-specific PROMs containing 116 scales and 32 single items with 94 different verbatim names. Identical names for scales were repeatedly used (for example, 'physical function' in six different measures) and others were similar (overlapping face validity) although component items were not always comparable. Based on methodological, clinical and patient expertise, 606 individual items were categorised into 32 health domains.

CONCLUSION

This study outlines a methodology for identifying candidate PRO domains from existing PROMs to inform a core outcome set to use in clinical trials.

Patterns of symptoms following surgery for esophageal cancer

PURPOSE/OBJECTIVE

To explore patterns of symptoms before and after surgery for cancer of the esophagus.

DESIGN

Longitudinal, descriptive study.

SETTING

An urban comprehensive cancer center in the northeastern United States.

SAMPLE

218 patients with cancer of the esophagus undergoing esophagectomy.

METHODS

Symptoms were assessed by self-report before surgery, at the first postoperative visit, and at 6 and 12 months postsurgery.

MAIN RESEARCH VARIABLES

Symptoms and demographic and clinical variables, including stage, treatment, gender, and comorbidities.

FINDINGS

Patients with esophageal cancer reported numerous symptoms before and after esophagectomy. Several patterns of symptoms were identified. General cancer symptoms (e.g., pain, cough, shortness of breath, weight loss) were reported as worse after surgery but recovered to baseline by one year. A second pattern of esophageal-specific symptoms (feeling full too quickly, feeling bloated, nausea, and diarrhea) worsened after surgery and did not recover to baseline by one year. Reflux was the only symptom that did not worsen after surgery but did worsen significantly during the first year of recovery.

CONCLUSIONS

Patients with esophageal cancer experienced multiple prolonged symptoms following surgical treatment for their disease. General cancer symptoms resolved by one year post-treatment, whereas esophageal-specific symptoms worsened after surgery and did not recover to baseline.

IMPLICATIONS FOR NURSING

Identification of symptom patterns preoperatively and during recovery can assist nurses in developing intervention protocols to minimize long-term complications for patients with esophageal cancer.

KNOWLEDGE TRANSLATION

Patients with esophageal cancer are at risk for multiple prolonged symptoms following surgery. Symptom assessment should occur often after surgery and include a broad range of symptoms.

Suboptimal intake of nutrients after esophagectomy with gastric tube reconstruction

Esophagectomy with gastric tube reconstruction results in a variety of postoperative nutrition-related complaints that can impair nutritional intake and nutritional status. The aim of this study was to determine to what extent patients reached the recommended intake of various nutrients at 6 and 12 months after esophagectomy. It was also analyzed whether a suboptimal intake could be explained by the most clinically significant nutrition-related complaints after esophagectomy. In a prospective cohort study (2002 to 2006), the nutrient intake of 96 patients, recorded in preprinted nutritional diaries, was compared with the recommended energy intake in The Netherlands and Recommended Dietary Allowance of protein and micronutrients. Energy and protein intake remained below recommendations in 24% and 7% of the patients, respectively. Less than 10% of the patients had a sufficient intake of all micronutrients. Folic acid, vitamin D, copper, calcium, and vitamin B-1 were the micronutrients most often reported to have a suboptimal intake. Multivariate logistic regression, corrected for preoperative epigastric pain and energy intake, showed that the number of nutrition-related complaints was not an independent risk factor for the presence of a suboptimal intake of nutrients (adjusted odds ratio=1.11; 95% CI: 0.94 to 1.31; P = 0.22). This study shows that the intake of micronutrients remains below recommendations in the majority of patients 12 months after esophagectomy. This problem requires special attention and care by registered dietitians.

Functional disorders and quality of life after esophagectomy and gastric tube reconstruction for cancer

Functional disorders such as delayed gastric emptying, dumping syndrome or duodeno-gastro-esophageal reflux occur in half of the patients who undergo esophagectomy and gastric tube reconstruction for cancer. The potential role for pyloroplasty in the prevention of functional disorders is still debated. Antireflux fundoplication during esophagectomy can apparently reduce the reflux but at the cost of increasing the complexity of the operation; it is not widely used. The treatment of functional disorders arising after esophagectomy and gastroplasty for cancer is based mainly on dietary measures. Proton pump inhibitors have well documented efficiency and should be given routinely to prevent reflux complications. Erythromycin may prevent delayed gastric emptying, but it should be used with caution in patients with cardiovascular disorders. In the event of anastomotic stricture, endoscopic dilatation is usually efficient. Problems related to gastrointestinal functional disorders after esophageal resection and gastric tube reconstruction do not significantly impair long-term quality of life, which is mainly influenced by tumor recurrence.

[Quality of life of patients with cancer of the oesophagus and stomach]

The study of the health related quality of life in patients with digestive tract cancer, and particularly in those with tumours of the oesophagus and stomach, provides useful information for selecting the most suitable therapeutic option. It may also be used to predict the impact of the disease and its possible treatments on the physical, emotional and social condition of the patient. Various sensitive and reliable tools have been developed over the past decades that are capable of measuring the quality of life of patients; the use of questionnaires has made it easier to exchange information between the patient and the doctor. The pre- and post-operative variations in the quality of life in patients with oesophageal-gastric cancer are of prognostic value on the outcome of the disease. For all these reasons, the health related quality of life is currently considered, along with disease free survival and absence of recurrences, one of the most important parameters in order to assess the impact on the patients of a particular oncological treatment. The aim of this article is to review the role of the health related quality of life assessment, as well as the various tools which are available to measure it in patients with oesophageal-gastric cancer.

Presence and persistence of nutrition-related symptoms during the first year following esophagectomy with gastric tube reconstruction in clinically disease-free patients

BACKGROUND

Esophagectomy with gastric tube reconstruction results in a variety of postoperative nutrition-related symptoms that may influence the patient's nutritional status.

METHODS

We developed a 15-item questionnaire, focusing on the nutrition-related complaints the first year after an esophagectomy. The questionnaire was filled out the first week after discharge and 3, 6, and 12 months after surgery. The use of enteral nutrition, meal size and frequency, social aspects related to eating, defecation pattern, and body weight were recorded at the same time points. We analyzed the relationship between the baseline characteristics and the number of nutrition-related symptoms, as well as the relationship between those symptoms and body weight with linear mixed models.

RESULTS

We found no significant within-patient change for the total number of nutrition-related symptoms (P = 0.67). None of the baseline factors were identified as predictors of the complaint scores. The most frequently experienced complaints were early satiety, postprandial dumping syndrome, inhibited passage due to high viscosity, reflux, and absence of hunger. One year after surgery, meal sizes were still smaller, the social aspects of eating were influenced negatively, and patients experienced an altered stool frequency. Directly after the surgical procedure 78% of the patients lost weight, and the entire postoperative year the mean body weight remained lower (P = 0.47). We observed no association between the complaint scores and body weight (P = 0.15).

CONCLUSIONS

After an esophagectomy, most patients struggle with nutrition-related symptoms, are confronted with nutrition-related adjustments and a reduced body weight.

Quality of Life after Emergency Vs. Elective Esophagectomy with Cervical Reconstruction

Introduction:

Esophagectomy with reconstruction by collar anastomosis has an impact on the patients' quality of life (QOL). The aim of this study was to explore a potential difference in QOL between elective and emergency esophagectomy with collar reconstruction.

Patients and Methods:

Quality of life questionnaires were evaluated in 17 patients prior to esophagectomy, shortly after surgery, hospital discharge, and at least > 9 months after surgery using the EORTC QLQ C30 and EORTC OES 18 forms. In all patients reconstruction was performed by high collar anastomosis. Patients in group A received elective esophageal resection. In group B emergency esophagectomy was performed because of esophageal perforation for various reasons apart from cancer. In this group, delayed reconstruction was performed in a second operation 3–6 months after esophagectomy.

Results:

There was a temporary decrease of postoperative QOL in both groups, which returned to preoperative values in the follow-up except for physical functioning, which remained decreased in group A (p < 0,05). There were no persisting differences in QOL after elective and emergency esophagectomy in the follow-up.

Discussion:

Patients with elective and emergency esophagectomy and reconstruction by high collar anastomosis gained a good long-term QOL in our cohort of patients. This gives evidence that the observed QOL after elective resection of esophageal cancer is not only caused by a relief of cancer burden, but also due to a surgical procedure which is able to provide a good long-term QOL.

Economic analysis of esophageal stenting for management of malignant dysphagia

Over half of patients diagnosed with esophageal cancer are unsuitable for curative resection. A significant proportion of these patients will subsequently require palliative stenting to alleviate dysphagia. There is growing consensus in the literature that the deployment of a Self-Expanding Metal Stent is the optimum stenting strategy; however, it remains unclear whether covered or uncovered metal stents are more cost-effective. In order to determine which type of prosthesis is more cost-effective, we compared the different stenting strategies in terms of 1-year stent-related mortality, health-related quality of life, and cost. A decision analytical model was constructed to compare the 1-year stent-related mortality, health-related quality of life, and cost between covered and uncovered stents. Probabilistic sensitivity analysis was performed to quantify the uncertainty associated with our results. Value of Information analysis was performed to assess the value of further research. In order to fully characterize the uncertainty associated with this decision, plastic stents were included in our analysis. Stent-related mortality was slightly lower following covered stent deployment compared with uncovered stent deployment (1.00% vs. 1.26%). Covered stents were more effective by 0.0013 Quality-Adjusted Life Years (Standard Deviation [SD] 0.0013 Quality-Adjusted Life Years). They were also less expensive by $729.58 (SD $390.63). Probabilistic sensitivity analysis suggested that these results were not sensitive to model parameter uncertainty. Plastic stents deployment was $2832.64 (SD $1182.72) more expensive than uncovered metal stent deployment. Value of Information analysis suggests that the maximum value of further research in the UK is $61,124.30. The results of this study represent strong evidence for the cost-effectiveness of covered compared with uncovered self-expanding metal stents for the palliation of patients with malignant dysphagia. The findings support previously published literature asserting the dominance of self-expanding metal stents over plastic stents. Value of Information analysis suggests that further research may not be cost-effective. These findings have significant implication for both current clinical practice and future clinical research.

The role of health-related quality of life outcomes in clinical decision making in surgery for esophageal cancer: a systematic review

BACKGROUND

Esophagectomy for cancer offers a chance of cure but is associated with morbidity, at least a temporary reduction in health-related quality of life (HRQL), and a 5-year survival of approximately 30%. This research evaluated how and whether HRQL outcomes contribute to surgical decision making.

METHODS

A systematic review identified randomized trials and longitudinal and cross-sectional studies that assessed HRQL after esophagectomy with multidimensional validated questionnaires. Articles were independently evaluated by two reviewers, and the value of HRQL in clinical decision making was categorized in three ways: (1) the assessment of the quality of HRQL methodology according to predefined criteria; (2) the influence of HRQL outcomes on treatment recommendations and/or informed consent; and (3) the HRQL after esophagectomy for cancer in methodologically robust studies.

RESULTS

Eighteen publications were identified, of which 16 (89%) were categorized as having robust HRQL design. Of these studies, 3 concluded that HRQL influenced treatment recommendations and 11 (including the former 3) informed patient consent. The remaining five papers were well designed, but the authors did not use HRQL to influence treatment recommendations or informed consent. After esophagectomy, patients report major deterioration in most aspects of HRQL with slow recovery.

CONCLUSION

HRQL outcomes are relevant to surgical decision making. Methods to communicate HRQL outcomes to patients are required to inform consent and clinical practice.

Impact of the site of anastomosis after oncologic esophagectomy on quality of life--a prospective, longitudinal outcome study

BACKGROUND

For patients undergoing oncologic surgery, the quality of life (QoL) is generally accepted as an important outcome parameter in addition to long-term survival, mortality, and complication rates. Our study focused on outcome in terms of QoL in patients with esophageal cancer, comparing the sites of anastomosis (cervical versus thoracic anastomosis).

METHODS

In a prospective longitudinal single-center study from 1998 to 2005, 105 patients underwent surgery for esophageal cancer. To assess QoL the EORTC-QLQ-C-30 and a tumor-specific module were administered before surgery, at discharge, and three, six, 12, and 24 months after surgery. Clinical data were collected prospectively and follow-up was performed every six months.

RESULTS

The histological type was squamous cell carcinoma in 51.4% of the cases, adenocarcinoma in 41.9%, and some other type in 6.7%. There was no significant difference between cervical and thoracic anastomosis with regard to morbidity, mortality, and survival rates (30% five-year survival rate), whereas tumor stage was a significant (p < 0.001) prognostic factor. Most QoL scores dropped significantly below baseline in the early postoperative period. Even though they recovered slowly during the follow-up period, they never reached preoperative levels again. There was no statistically significant difference in any of the QoL scales between patients with a cervical or a thoracic anastomosis.

CONCLUSIONS

Esophageal resections are associated with significant deterioration of QoL, which persists during the follow-up period. The surgical technique and position of the esophagogastrostomy did not affect QoL deterioration.

Remapping the body: learning to eat again after surgery for esophageal cancer

Surgery for esophageal cancer offers the hope of cure but might impair quality of life. The operation removes tumors obstructing the esophagus but frequently leaves patients with eating difficulties, leading to weight loss. Maintaining or increasing body weight is important to many patients, both as a means of returning to "normal" and as a means of rejecting the identity of the terminal cancer patient, but surgery radically alters embodied sensations of hunger, satiety, swallowing, taste, and smell, rendering the previously taken-for-granted experience of eating unfamiliar and alien. Successful recovery depends on patients' learning how to eat again. This entails familiarization with physiological changes but also coming to terms with the social consequences of spoiled identity. The authors report findings from in-depth interviews with 11 esophageal cancer patients, documenting their experiences as they struggle to achieve a process of adaptation that is at once physiological, psychological, and social.

Quality of life in patients with oesophageal and gastric cancer: an overview

An accurate assessment of health-related quality of life (QoL) in patients with oesophageal or gastric cancer (OGC) is essential to inform clinical decisions by providing insights into patients' experiences of the impact of the disease and its treatments on physical, social and emotional health. Robust QoL questionnaires have been developed and validated in the past decade to measure the QoL of OGC patients. Baseline QoL variables are also prognostic for survival in patients with oesophageal cancer or metastatic gastric cancer. This article reviews the impact of surgery and reconstructive techniques, as well as of adjuvant and palliative treatments on the QoL of patients with OGC.

Experiences and expectations of patients after oesophageal cancer surgery: an explorative study

We investigated which problems patients experience after resection for oesophageal cancer and what care they expect, in order to devise a better-tailored follow-up policy. Thirty patients, all within 1 year after surgery, filled in a one-time questionnaire on experienced physical, psychological and social problems and on expected care for these problems. Additionally, a semi-structured interview was performed. Frequencies of experienced problems and expected care over time were analysed. The majority of patients experienced physical problems such as 'early satiety' (97%) and 'fatigue' (84%) after oesophagectomy. In addition, patients often felt depressed (64%), were afraid of metastases (80%) and death (47%). Over time, the frequency of problems such as 'fatigue' (P = 0.035) and 'being dependent' (P = 0.012) decreased. Patients particularly expected professional care for physical issues related to their disease, whereas they often managed psychosocial problems in their own social network. Patients indicated that nurses' involvement during follow-up might improve their possibility to satisfactorily deal with problems. Patients frequently experience physical problems after oesophagectomy, and professional care is expected for these issues. Psychosocial problems are also present, but care is less commonly expected. Nurses' involvement during follow-up could be a way to optimize patients' management after oesophageal cancer surgery.

A comparative longitudinal quality of life study using the Spitzer quality of life index in a randomized multicenter phase III trial (FFCD 9102): chemoradiation followed by surgery compared with chemoradiation alone in locally advanced squamous resectable thoracic esophageal cancer

BACKGROUND

The aim of the study was to compare the longitudinal quality of life (QoL) between chemoradiation with or without surgery in patients with locally advanced squamous resectable esophageal cancer included in a randomized multicenter phase III trial (FFCD 9102).

MATERIALS AND METHODS

All patients with locally advanced resectable (T3-4 N0-1 M0) epidermoid or glandular esophageal cancer (n = 451) received induction chemoradiation. Responders (n = 259) were randomized between surgery (arm A) and continuation of chemoradiation (arm B). The Spitzer QoL Index was scored (0-10) at inclusion and at each follow-up, every 3 months during 2 years. QoL at baseline and longitudinal changes were respectively compared with univariate ANOVA and mixed-model analysis of variance for repeated measurements. The time interval between the follow-up was assessed and the same analyses were performed among survivors with 2 years of follow-up.

RESULTS

The squamous histology was predominant in both arms. The mean QoL score decreased between baseline and the first follow-up and between the first and the second follow-ups. QoL scores at the first follow-up were comparatively worse in arm A than in arm B (7.52 versus 8.45, P < 0.01), whereas the longitudinal QoL study showed no difference between treatments (adjusted P = 0.26). Furthermore, the longitudinal QoL was not different (adjusted P = 0.23) among survivors with 2 years of follow-up.

CONCLUSIONS

Among patients responding to induction chemoradiation, surgery and continuation of chemoradiation had the same impact on QoL in patients with locally advanced, resectable esophageal cancer although a significantly greater decrease in the Spitzer Index was observed in the postoperative period.

Long-term function and quality of life after esophageal resection for cancer and Barrett's

Esophagectomy is the treatment of choice for cancer or high-grade dysplasia. Although the patients frequently experience symptoms postoperatively, their quality of life is most often comparable to that of a control population. This article provides details of post-esophagectomy symptomatology and examines how quality of life can be measured in these patients.

Quality of life after transhiatal compared with extended transthoracic resection for adenocarcinoma of the esophagus

PURPOSE

To assess 3 years of quality of life in patients with esophageal cancer in a randomized trial comparing limited transhiatal resection with extended transthoracic resection.

PATIENTS AND METHODS

Quality-of-life questionnaires were sent at baseline and at 5 weeks; 3, 6, 9, and 12 months; and 1.5, 2, 2.5, and 3 years after surgery. Physical and psychological symptoms, activity level, and global quality of life were assessed with the disease-specific Rotterdam Symptom Checklist. Generic quality of life was measured with the Medical Outcomes Study Short Form-20.

RESULTS

A total of 199 patients participated. Physical symptoms and activity level declined after the operation and gradually returned toward baseline within the first year (P < .01). Psychological well-being consistently improved after baseline (P < .01), whereas global quality of life showed a small initial decline followed by continuous gradual improvement (P < .01). Quality of life stabilized in the second and third year. Three months after the operation, patients in the transhiatal esophagectomy group (n = 96) reported fewer physical symptoms (P = .01) and better activity levels (P < .01) than patients in the transthoracic group (n = 103), but no differences were found at any other measurement point. For psychological symptoms and global quality of life, no differences were found at any follow-up measurement. A similar pattern was found for generic quality of life.

CONCLUSION

No lasting differences in quality of life of patients who underwent either transhiatal or transthoracic resection were found. Compared with baseline, quality of life declined after the operation but was restored within a year in both groups.

Quality of life after esophagectomy

Esophagectomy is associated with high complication rates and consequent mortality. The 5-year survival for esophageal cancer is also discouraging with rates of 6 to 33% after surgery. Nonsurgical series of selected patients have shown similar survival. Therefore, quality of life may be a better assessment of patient outcomes than survival. At present few reports have address quality of life in patients after esophagectomy, particularly in those patients who succumb quickly to recurrent cancer. This article investigates the determinants of quality of life after esophagectomy and reviews the use of quality of life measures in comparative trials. Quality of life measures may become valuable tools in the selection of patients for esophagectomy.

Clinical and psychometric validation of an EORTC questionnaire module, the EORTC QLQ-OES18, to assess quality of life in patients with oesophageal cancer

Quality of life (QOL) assessment requires clinically relevant questionnaires that yield accurate data. This study defined measurement properties and the clinical validity of the European Organisation for Research and Treatment of Cancer (EORTC) questionnaire module to assess QOL in oesophageal cancer. The oesophageal module the QLQ-OES24 and core questionnaire, the Quality of Life-Core 30 questionnaire (QLQ-C30) was administered patients undergoing treatment with curative (n=267) or palliative intent (n=224) and second assessments performed 3 months or 3 weeks later respectively. Psychometric tests examined scales and measurement properties of the module. Questionnaires were well accepted, compliance rates were high and less than 2% of items had missing data. Multi-trait scaling analyses and face validity refined the module to four scales and six single items (QLQ-OES18). Selective scales distinguished between clinically distinct groups of patients and demonstrated treatment-induced changes over time. The EORTC QLQ-OES18 demonstrates good psychometric and clinical validity. It is recommended for use with the core questionnaire, the QLQ-C30, to assess QOL in patients with oesophageal cancer.

Quality of life after esophagectomy for cancer

PURPOSE/OBJECTIVES

To examine symptoms and quality of life (QOL) of esophagectomy patients after curative surgery.

DESIGN

Longitudinal, descriptive pilot study.

SETTING

Comprehensive cancer center in the northeastern United States.

SAMPLE

23 patients were surveyed: 20 men and 3 women. The mean age was 62.3 years.

METHODS

The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (version 2.0) and the esophageal-specific module were used. Data collection included three or four time points: before neoadjuvant treatment (if administered), before surgery, and three and six months after surgery.

MAIN RESEARCH VARIABLES

The effects on symptoms and QOL of curative esophagectomy performed by a thoracic surgical oncologist.

FINDINGS

Global QOL declined slightly over time; this change was not statistically significant. A significant inverse relationship was found between symptom intensity and global QOL. The intensity of hoarseness, reflux, and diarrhea increased significantly pre- to postsurgery. The average symptom intensity for the esophageal-specific subset of 24 symptoms increased significantly over time; the greatest intensity was found before surgery.

CONCLUSIONS

Over the six-month observation period, the study found little average change in global QOL or functional status. However, symptoms increased significantly during this time period. Increased symptoms were associated with decreased QOL.

IMPLICATIONS FOR NURSING

Symptom management should focus on symptoms that interfere with patients' QOL. Further research should target the evaluation of specific interventions for symptoms.

Pain, function, and psychologic outcome before, during, and after intraoral tumor resection

PURPOSE

The aim of the present study was to determine the quality of life of patients with respect to pain before, during, and after ablative intraoral tumor surgery.

PATIENTS AND METHODS

The Bochum Questionnaire on Rehabilitation was used to determine 147 items including the morphologic, functional, and psychosocial aspects of rehabilitation. One thousand six hundred fifty-two of 3,500 patients (47.2%) (413 women and 1,239 men) completed the questionnaire. The statistical investigation was carried out using 2-sample (independent) and paired (dependent) t tests.

RESULTS

Pain and the functional impairment of chewing and swallowing are the most important parameters before treatment. Immediately after surgical treatment, other variables, such as speech intelligibility and mobility disorders in the head, neck, and shoulder regions, became more apparent. Pain was reported in the shoulder region in 38.5% and in the neck in 34.9% of patients after surgery. The temporomandibular joint was painful in 20.1%, the oral cavity in 18.7%, and the face in 8.2%. Pain was described by 7.4% of patients in other regions of the head. Seventy-five percent of 1527 patients were not taking pain medications during the investigation. The rate of physiotherapy consequently applied after surgery was less than 10%.

CONCLUSIONS

Quality of life after ablative intraoral surgery is not greatly affected by pain. Because functional disorders play the dominant role in the impairment of postoperative quality of life, functional reconstruction, using microvascular techniques, and early rehabilitation, including physiotherapy, should be intensified.

A randomized trial of thermal ablative therapy versus expandable metal stents in the palliative treatment of patients with esophageal carcinoma

BACKGROUND

Expandable metal stent insertion and thermal tumor ablation (TTA) both improve dysphagia in patients with advanced esophageal cancer, but no direct comparison study of their efficacy on health-related quality of life has been published. The aim of this study was to compare survival, relief of dysphagia, quality of life, and cost in patients treated by thermal ablation or stent insertion.

METHODS

Sixty-five patients with histologically proven, inoperable esophageal and esophagogastric cancer were initially assessed by endoscopy, barium contrast radiography, and CT of the thorax and abdomen. Dysphagia and quality of life were serially assessed at monthly intervals. Patients were randomized to either repeated TTA or insertion of an expandable metal stent.

RESULTS

Median survival was significantly longer for patients who underwent TTA; 125 days (17-546) versus 68 days (8-602) for those in whom a stent was inserted (p < 0.05), although relief of dysphagia was disappointing in both groups. Several patients in both groups had serious treatment-related complications and required further therapy. Median length of hospital stay and cost were greater for patients treated by TTA. Health-related quality of life was globally impaired in both groups at randomization and deteriorated significantly in the stent group. Pain was reported more commonly by patients with stents.

CONCLUSIONS

The palliation of patients with advanced esophageal and esophagogastric cancer remains unsatisfactory. Health-related quality of life deteriorated in the stent group but not in the TTA group. Patients treated by TTA live longer than patients treated by stent insertion, but the cost of TTA is higher.

Measurement of outcome

The outcomes of treatment of oesophageal cancer include traditional biological and physical measures, such as mortality and morbidity data, disease free and overall survival, clinical and pathological response rates and symptom control. Such factors are essential and should be recorded prospectively for clinical audit. Using this type of information alone to evaluate effectiveness of treatment is inadequate, however, because the diagnosis and treatment of oesophageal cancer has a major impact on functional well-being (including psycho-social function), general health perceptions and overall quality of life (QL)/satisfaction with health and health care. These aspects of patients' well-being need to be considered, in addition to standard outcomes in the evaluation of treatment of oesophageal cancer. Recent needs to judge the economic efficiency of health care by comparing health outcomes with costs may also be part of treatment appraisal. This article reviews surgical, oncological, patient-based and economic outcomes in oesophageal cancer.

Quality of life in patients with cancers of the upper gastrointestinal tract

Accurate assessment of health-related quality of life in patients with upper gastrointestinal cancers is essential to help determine treatment strategies. Questionnaires may be used to screen for physical and psychosocial morbidity, to evaluate new therapies and there is accumulating evidence to suggest that quality of life scores have prognostic value. There are well validated generic measures of quality of life suitable to use in patients with cancers of the upper gastrointestinal tract, but only two systems (EORTC QLQ-C30 and the FACT-G) have site-specific modules that have been constructed for this patient group. The future use of computer-assisted techniques to collect, analyze and interpret quality of life data will enable the implementation of quality of life results in clinical practice.

Quality of life in long-term survivors after curative transhiatal oesophagectomy for oesophageal carcinoma

BACKGROUND

Transhiatal resection for oesophageal cancer is a major operation with potentially severe physical, emotional and social consequences. The aim of this study was to assess various aspects of quality of life in long-term survivors following oesophageal resection for cancer.

METHODS

Between January 1993 and May 1996, 100 consecutive patients with cancer of the oesophagus or oesophagogastric junction underwent a potentially curative transhiatal oesophagectomy. Patients with a minimum follow-up of 2 years and with no tumour recurrence (n = 35) were mailed questionnaires which consisted of: (a) the Short Form-36 Health Survey to assess general quality of life, (b) an adapted Rotterdam Symptom Checklist to assess disease-specific quality of life, and (c) additional questions about other effects of the operation.

RESULTS

All patients returned the questionnaire. General quality of life was comparable with reference values for the same age group. However, more than half of the patients still experienced at least some early satiety, fatigue, dysphagia, heartburn and/or psychological irritability. Nine of 13 patients who worked in paid employment before operation continued to do so.

CONCLUSION

Patients who survive 2 years or more after transhiatal oesophageal resection for cancer can lead satisfactory lives. Although some residual symptoms may persist, their general quality of life is similar to that of healthy individuals of the same age.

Quality of life in patients with oesophageal cancer

There is a growing interest in assessing quality of life in patients with oesophageal cancer because it provides detailed information of the patients' perception of the benefits or harms of treatment. Yet few studies have prospectively measured quality of life using validated appropriate instruments. There are now several questionnaires for patients with cancer, although these are not sufficiently sensitive to small but clinically important changes in quality of life. It is therefore recommended that a disease-specific module is used in conjunction with generic measures. The European Organisation into Research and Treatment of Cancer (EORTC) QLQ-OES24 is currently completing an international validation study. It is used with the EORTC QLQ-C30 core instrument and is designed for patients undergoing potentially curative treatment or palliation of malignant dysphagia. Studies that have assessed quality of life after oesophagectomy have generally found that survivors do regain their former health. Little is known about the effect of neoadjuvant chemoradiation on patients' quality of life. Following endoscopic palliation of dysphagia, quality of life can be maintained and improvement of swallowing is seen. A validated appropriate assessment of quality of life should be included in future palliative trials and in studies of new treatments which may marginally influence survival but cause significant side effects.

Speech, deglutition and life quality after intraoral tumour resection. A prospective study

The aim of the present prospective study was to evaluate the functional sequelae and postoperative development of quality of life after intraoral tumour surgery in 40 consecutive patients with a squamous cell carcinoma of the floor of the mouth. Immediate reconstruction of intraoral soft tissues after tumour resection was accomplished by local flaps (cheek and tongue) (n=27) and by revascularized transfer of small bowel grafts (n=5) and myocutaneous/fasciocutaneous flaps (n=8). Mobility of the tongue was assessed by ultrasound. Quality of speech was analysed using the Freiburg speech intelligibility test. Life quality was assessed by the functional living index-cancer preoperatively and six months postoperatively. A significant decrease in both mobility of the tongue and quality of speech was registered. The most substantial effect on quality of speech resulted from decreased movement of the base and the dorsum of the tongue. A significant increase in life quality at the end of the study period occurred only in the group of patients without substantial reduction of intelligibility of speech, while no significant improvement of postoperative life quality of patients with more severe deterioration of speech quality was found.

Esophageal resection for cancer of the esophagus: long-term function and quality of life

BACKGROUND

Information on function and quality of life of long-term survivors after esophageal resection for carcinoma is limited.

METHODS

Between 1972 and 1990, 359 patients underwent esophagectomy for stage I or II esophageal carcinoma at Mayo Clinic. We evaluated long-term function and quality of life in 107 of these patients (81 men and 26 women) who survived 5 or more years. Median age at operation was 62 years (range, 30 to 81 years). The operation performed was an Ivor Lewis resection in 77 patients (72%), transhiatal esophagectomy in 14 (13%), extended esophagectomy in 4 (4%), thoracoabdominal esophagectomy in 4 (4%), and other in 8 (7%). Adenocarcinoma was present in 72 patients (67%), squamous cell carcinoma in 28 (26%), and other in 7 (7%). Thirty-four patients (32%) were in postsurgical stage I, 65 (61%) in stage IIA, and 8 (8%) in stage IIB. Median survival was 10.2 years (range, 5.0 to 23.2 years). Follow-up was complete for all patients.

RESULTS

Gastroesophageal reflux was present in 64 patients (60%), symptoms of dumping in 53 (50%), and dysphagia to solid food in 27 (25%). Seventeen patients (16%) were asymptomatic. Factors affecting late functional outcome were analyzed. Patients who had a cervical anastomosis had significantly fewer reflux symptoms (p < 0.05). Dumping syndrome occurred more frequently in younger patients (p < 0.05) and women (p < 0.01). Quality of life was assessed separately by the Medical Outcomes Study 36-Item Short-Form Health Survey and compared with the national norm. Scores measuring physical functioning were decreased (p < 0.01). Scores measuring ability to work, social interaction, daily activities, emotional dysfunction, perception of health, and levels of energy were similar. Mental health scores were higher (p < 0.05).

CONCLUSIONS

We conclude that long-term functional outcome after esophagectomy for esophageal carcinoma is affected by age, sex, and type of reconstruction. Quality of life as judged by the patients is similar to the national norm.

Quality of life following resection of oesophageal carcinoma

Quality of life following resection of oesophageal carcinoma was assessed by patients using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and by a psychologist using the Spitzer Index. Quality of life was evaluated in 119 patients on one occasion 12 months after operation and in 30 patients regularly, starting with a preoperative assessment. Self and external evaluation showed a significant correlation (r = 0.61), but quality of life was assessed as being higher by the external observer. Limited physical performance status and somatic complaints were the most important postoperative dysfunctions, whereas emotional, social and economic disorders were found to be less frequent and less severe. Of several factors analysed only tumour recurrence (P < 0.01) and anastomotic stricture (P < 0.05) lowered quality of life significantly. Compared with the preoperative assessment, quality of life had decreased on discharge from hospital but was restored within 6 months of operation in disease-free patients. Further studies are required to determine the impact of adjuvant therapy for quality of life in patients undergoing surgery for oesophageal cancer.

Changes in quality-of-life scores in a population of patients treated for squamous cell carcinoma of the head and neck

BACKGROUND

Quality of life levels fluctuate depending on treatment type and at various points throughout treatment. In patients with advanced head and neck cancer, quality of life is thought to be treatment dependent. The purpose of this study is to compare levels of patients self-reported quality of life across treatment.

PATIENTS AND METHODS

Preliminary data presented here are based on 24 patients enrolled so far in an experimental organ-preservation protocol. The two treatment groups consist of one group treated with chemotherapy (paclitaxel and carboplatin) followed by radiation therapy and the second group which is treated with chemotherapy (paclitaxel and carboplatin) followed by surgery and postoperative radiation. Data is collected pretreatment and at uniform points throughout the course of treatment.

RESULTS

Preliminary results suggest that quality of life is significantly higher in the nonsurgical group than in the surgical group at the last treatment point reported. Social distress/avoidance is also lower in the nonsurgical group. Because of the small number of patients represented in this study, results should be interpreted with caution and should be viewed as descriptive at this juncture.

CONCLUSION

Quality of life seems to be preserved in patients who experience less invasive and disfiguring treatment, and who also have compromised eating and communication abilities. Data collection in this study is ongoing.

Development of an EORTC questionnaire module to be used in quality of life assessment for patients with oesophageal cancer. The EORTC Quality of Life Study Group

Quality of life (QOL) assessments in patients with oesophageal cancer should provide clinically meaningful data that can assist management decision making. This study describes the development of a specific module for oesophageal cancer to use with the European Organisation into Research and Treatment of Cancer (EORTC) QOL questionnaire, the EORTC QLQ-C30. Relevant QOL issues were generated from a literature search and interviews with patients and oesophageal cancer specialists. Issues were formulated into items compatible with those of the EORTC QLQ-C30. The provisional module was pretested in patients from the United Kingdom, Spain and Sweden. The resulting module, the QLQ-OES 24, includes 24 items conceptualised as containing six scales and five single items. The addition of an oesophageal cancer-specific module to the core questionnaire should improve the sensitivity and specificity of the core instrument to allow detection of even small benefits accrued from new treatment modalities.

Measuring quality of life in oncology: is it worthwhile? II. Experiences from the treatment of cancer

This is the second part of the paper on quality of life in cancer patients which appeared in this journal (Montazeri et al., 1996a). In this part experiences from the treatment of cancer are given and relevant literature is reviewed. Several topics have been covered, including new directions and methods in assessing quality of life. It is argued that in a chronic condition, adding life to years instead of years to life is an important task. Adding years to life may prolong survival, but whether this is to the benefit of patients is debatable. Considering patients' views, their values and preferences may improve the quality of care and at the same time, reduce the psychological distress and physical discomfort in patients with cancer. It is concluded that quality of life measures have considerable potential in this challenging issue.

Prospective study of the quality of life of cancer patients after intraoral tumor surgery

PURPOSE

The aim of this prospective study was to determine the quality of life of patients with oral cancer after intraoral ablative surgery.

PATIENTS AND METHODS

Eighty-five consecutive patients with squamous cell carcinoma of the floor of the mouth were enrolled in the study. Reconstruction of intraoral soft tissues was accomplished by local tissue (67.8%), jejunal grafts (16.9%), and cutaneous and myocutaneous flaps (15.3%). Soft tissue resections were combined with resections of the alveolar process of the mandible in 35.0% and mandibular discontinuity resections in 31.7% of the cases. A self-administered, standard questionnaire consisting of 22 visual analog scale items with a maximum index value of 154 was used to determine the physical functional status, the psychological status, and social functioning of cancer patients (Functional Living Index--Cancer). The questionnaire was administered preoperatively and 3, 6, and 12 months postoperatively.

RESULTS

The Functional Living Index score increased significantly toward the end of the first postoperative year because of an increase in all three factors of the scale. All modes of soft tissue reconstruction achieved nearly equal levels of life quality in patients with median or lateral defects at the end of the observation period. Only patients with large bilateral defects exhibited lower preoperative and postoperative values because of extensive loss of functionally important soft tissue. Patients with discontinuity resections of the mandible took longer to regain the same level of life quality as patients without bone resections. Persistence of dysphagia, reflux of liquids, limitations to liquid food, and sleep disorders had a significant negative effect on the score.

CONCLUSIONS

It is concluded that rehabilitation of oral cancer patients is particularly difficult in the case of large soft tissue defects and is not always accomplished completely even with primary microsurgical tissue repair.

Quality-of-life assessment in patients undergoing treatment for oesophageal carcinoma

In a prospective study of 69 patients being treated for oesophageal carcinoma, quality of life was assessed with the Rotterdam Symptom Checklist, a dysphagia score and an activities of daily living questionnaire. Significant correlations were found between the results of the Rotterdam Symptom Checklist, the dysphagia score and most aspects of the activities of daily living questionnaire. Eighteen patients underwent surgery, 43 radiotherapy or intubation, and eight a combination of surgery and other therapy. Patients undergoing surgery were significantly younger and had better scores in all parameters examined before operation, including significantly better scores in 'knowledge and communication' and 'mobility and fatigue'. The dysphagia score fell significantly after intervention both in patients undergoing surgery alone and in those receiving palliative therapy. The activities of daily living questionnaire showed significant improvements in two parameters in the surgical group ('self-care' and 'eating and drinking') and in none of the parameters assessed in the palliation group in 16 weeks. Quality-of-life assessment is useful in assessing quality of care and patient well-being after the diagnosis and treatment of oesophageal carcinoma.

Observer variation in assessment of quality of life in patients with oesophageal cancer

Quality of life (QOL) assessment may improve the evaluation of treatment for oesophageal cancer but patient compliance using self completion questionnaires is often poor. The use of a proxy to estimate QOL might improve data collection from patients who are either unable or unwilling to complete the questionnaire. This study examined whether a doctor or patients' carers could accurately assess QOL using the QLQ-C30 questionnaire developed by the European Organisation for Research and Treatment of Cancer Study Group on Quality of Life. One doctor, 52 patients and 39 carers completed the instrument independently. Proxy and patient ratings were analysed for agreement using weighted kappa scores. Agreement was poor or moderate in most QOL scales and items (kappa < or = 60). This study demonstrates that a carer or doctor is not sufficiently accurate to postulate the patient's responses to the questionnaire. Quality of life data, therefore, should come from the patients themselves.
