Validation of the reflux scale in the European Organisation for Research and Treatment of Cancer QLQ-OES18

Severe Reflux and Symptoms of Anxiety and Depression After Esophageal Cancer Surgery

BACKGROUND

Approximately 30% of patients suffer from severe reflux after surgery for esophageal cancer, which may serve as a continuous reminder of the cancer and catalyze fear of recurrence.

OBJECTIVE

The aim of this study was to investigate the association between severe reflux and symptoms of anxiety and depression after esophageal cancer surgery.

METHODS

This was a nationwide prospective cohort study including all Swedish patients who underwent esophageal cancer surgery between 2013 and 2018. Patients reported reflux on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire module for gastroesophageal symptoms and psychological distress on the Hospital Anxiety and Depression Scale at 1 and 2 years after surgery. Repeated-measures logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs), adjusted for age, sex, comorbidity, body mass index, TNM classification, neoadjuvant therapy, surgery type, postoperative complications, antireflux medication, and elevated headrest at night.

RESULTS

Among 154 included patients, 43 (28%) and 37 (24%) reported severe reflux 1 and 2 years after surgery, respectively. No association between severe reflux and anxiety (OR, 2.1; 95% CI, 0.7-6.3) or depression (OR, 1.2; 95% CI, 0.3-4.6) was found 1 year after surgery. After 2 years, there was still no association between severe reflux and anxiety (OR, 0.9; 95% CI, 0.3-2.8) or depression (OR, 1.2; 95% CI, 0.5-3.3).

CONCLUSIONS

Findings suggest that severe reflux is not associated with anxiety or depression after esophageal cancer surgery.

IMPLICATIONS FOR PRACTICE

For esophageal cancer survivors, other factors than severe reflux may be more important for the psychological recovery.

Translation, validation of the EORTC esophageal cancer quality-of-life questionnaire for Japanese with esophageal squamous cell carcinoma: analysis in thoraco-laparoscopic esophagectomy versus open esophagectomy

OBJECTIVE

The aim of this study is to develop and examine the reliability and validity of the Japanese version of the European Organization for Research and Treatment of Cancer quality-of-life questionnaire-esophageal cancer (OES18) module for its use in Japan.

METHODS

We followed a two-phase process to translate the questionnaire, according to the guidelines of the European Organization for Research and Treatment of Cancer OES18. Phase 1: the first intermediary Japanese version was produced according to European Organization for Research and Treatment of Cancer quality-of-life unit translation project guidelines. The second intermediary version was the result of a backward translation project and two peer-to-peer discussion by healthcare professionals. Phase 2: the final Japanese version was produced after focus group discussions with team members and semistructured interviews.

RESULTS

Fifty patients with esophageal squamous cell carcinoma, who had undergone curative thoracic esophagectomy, participated in the study. The Japanese translated version of quality-of-life questionnaire-OES18 yielded cultural adaptation and validation scores whose reliability was confirmed by internal consistency tests. Convergent validity was moderate to high (from r = 0.671-0.903; P < 0.01), whereas discriminant validity was acceptably low. Significant reduction in pain-scale values was noted postoperatively in the thoracoscopic approach when compared with the thoracotomy approach (scale value: 9.62 vs. 12.71; P = 0.04).

CONCLUSIONS

We developed the Japanese version of quality-of-life questionnaire-OES18. This module has good psychometric validity and recommended to assess the health-related quality of life in Japanese patients.

Embedded Three-Layer Esophagogastric Anastomosis Reduces Morbidity and Improves Short-Term Outcomes After Esophagectomy for Cancer

BACKGROUND

There exists great controversy regarding the use of esophagogastric anastomotic techniques in the treatment of esophageal cancer. The aim of this study was to compare two types of cervical esophagogastric anastomoses with respect to the reduction of postoperative anastomotic leaks, stenosis, and gastroesophageal reflux.

METHODS

From June 2010 to September 2013, 339 patients who underwent two different cervical esophagogastric anastomotic procedures after thoracolaparoscopic esophagectomy for esophageal cancer were identified.

RESULTS

A total of 166 patients with esophageal cancer were treated using an embedded three-layer anastomosis (embedded group), and 173 were treated using a conventional two-layer anastomosis (conventional group). The rates of anastomotic leak (2.4% [4 of 166] versus 7.5% [13 of 173], p = 0.031) and benign anastomotic stricture (4.8% [8 of 166] versus 12.7% [22 of 173], p = 0.010) were significantly lower in the embedded group compared with the conventional group. The mean reflux scores were significantly higher among the patients in the conventional group compared with the patients in the embedded group at 1 month (25.2 versus 19.0, p = 0.001), 3 months (27.8 versus 21.4, p = 0.001), and 6 months (23.4 versus 17.8, p < 0.001) of follow-up. The mean scores for dysphagia were significantly lower among the patients in the embedded group compared with the patients in the conventional group at both 3 months (22.7 versus 29.8, p = 0.012) and 6 months (16.0 versus 21.3, p = 0.008) of follow-up.

CONCLUSIONS

The new embedded three-layer esophagogastric anastomosis offers several advantages and reduces the incidence of postoperative complications such as anastomotic leak, stricture, and gastroesophageal reflux.

Systematic review: questionnaires for assessment of gastroesophageal reflux disease

Numerous questionnaires with a wide variety of characteristics have been developed for the assessment of gastroesophageal reflux disease (GERD). Four well-defined dimensions are noticeable in these GERD questionnaires, which are symptoms, response to treatment, diagnosis, and burden on the quality of life of GERD patients. The aim of this review is to develop a complete overview of all available questionnaires, categorized per dimension of the assessment of GERD. A systematic search of the literature up to January 2013 using the Pubmed database and the Embase database, and search of references and conference abstract books were conducted. A total number of 65 questionnaires were extracted and evaluated. Thirty-nine questionnaires were found applicable for the assessment of GERD symptoms, three of which are generic gastrointestinal questionnaires. For the assessment of response to treatment, 14 questionnaires were considered applicable. Seven questionnaires with diagnostic purposes were found. In the assessment of quality of life in GERD patients, 18 questionnaires were found and evaluated. Twenty questionnaires were found to be used for more than one assessment dimension, and eight questionnaires were found for GERD assessment in infants and/or children. A wide variety of GERD questionnaires is available, of which the majority is used for assessment of GERD symptoms. Questionnaires differ in aspects such as design, validation and translations. Also, numerous multidimensional questionnaires are available, of which the Reflux Disease Questionnaire is widely applicable. We provided an overview of GERD questionnaires to aid investigators and clinicians in their search for the most appropriate questionnaire for their specific purposes.
