Is a single-item visual analogue scale as valid, reliable and responsive as multi-item scales in measuring quality of life?

Purpose: To compare the validity, reliability and responsiveness of a single, global quality of life question to multi-item scales. Method: Data were obtained from 83 consecutive patients with oesophageal adenocarcinoma undergoing either transhiatal or transthoracic oesophagectomy. Quality of life was measured at baseline, 5 weeks, 3 and 12 months post-operatively with a single-item Visual Analogue Scale (VAS) ranging from 0 to 100, the multi-item Medical Outcomes Study Short Form-20 (MOS SF-20) and Rotterdam Symptom Check-List (RSCL). Convergent and discriminant validity, test–retest reliability and both distribution-based and anchor-based responsiveness were evaluated. Major findings: At baseline and at 5 weeks, the VAS showed high correlations with the MOS SF-20 health perceptions scale (r = 0.70 and 0.72) and moderate to high correlations with all other subscales of the MOS SF-20 and RSCL (r = 0.29–0.70). The test–retest reliability intra-class correlation for the VAS was 0.87. At 5 weeks post-operatively, the distribution-based responsiveness was moderate for the VAS (standardised response mean: −0.47; effect size: −0.56), high for the physical subscales of the MOS SF-20 and RSCL (−1.08 to −1.51) and low for the psychological subscales (0.11 to −0.25). Five weeks post-operatively, anchor-based responsiveness was highest for the VAS (r = 0.54). Conclusion: The VAS is an instrument with good validity, excellent reliability, moderate distribution-based responsiveness and good anchor-based responsiveness compared to multi-item questionnaires. Its use is recommended in clinical trials to assess global quality of life.

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.

Individualised Surgical Treatment of Patients with an Adenocarcinoma of the Distal Oesophagus or Gastro-Oesophageal Junction

In this review we discuss the different strategies to improve surgical outcomes after potentially curative resection for oesophageal adenocarcinoma. For tumours of the distal oesophagus, there is a 17% survival benefit after transthoracic resection with two-field lymph node dissection when compared with transhiatal resection. This survival benefit is absent for tumours of the gastro-oesophageal junction or gastric cardia. These patients should, in the absence of tumour-positive lymph nodes at or proximal to the carina, undergo a transhiatal resection to minimise peri-operative complications. New developments include endoscopic resection or minimally invasive oesophagectomy, but these therapies should still be considered experimental.

Laparoscopy and laparoscopic ultrasonography in staging carcinoma of the gastric cardia.

Objective: To investigate the role of diagnostic laparoscopy and laparoscopic ultrasonography in the staging of carcinoma of the gastric cardia that is involving the distal oesophagus. Design: Retrospective consecutive case series. Setting: Tertiary care centre, The Netherlands. Subjects: 48 patients (34 men and 14 women, median age 63 years, range 39-84) who presented with tumours of the gastric cardia that involved the distal oesophagus and in whom non-invasive staging had not shown unresectable locoregional disease or distant metastases. Interventions: In addition to laparoscopy and laparoscopic ultrasonography, biopsy of all suspected lesions outside the area of potential resection. Main outcome measures: Number of patients in whom the findings obviated the need for exploratory laparotomy. Results: There were no complications related to the laparoscopy. The investigation showed distant metastases (which were histologically verified) in 11 patients (23%, 95% confidence interval (CI) 16 to 30). These pa...

Prospective analysis of patients with adenocarcinoma of the gastric cardia and lymph node metastasis in the proximal field of the chest.

The extent to which adenocarcinoma of the cardia with lymph node metastasis in the upper mediastinum is amenable to cure by radical surgery is open to debate. It remains unclear whether these relatively distant metastases have an effect on long‐term survival. The aim of this study was to identify the incidence of such positive nodes and evaluate their prognostic significance.

Effects of prolonged intensive care unit stay on quality of life and long-term survival after transthoracic esophageal resection

Objective:There are few prospective data on the effects of prolonged intensive care unit stay on the quality of life and long-term survival of a homogeneous patient population. Therefore, the aims of this prospective study were a) to describe the quality of life in patients after having a transthoracic esophageal resection; and b) to analyze the influences of a prolonged intensive care unit stay on quality of life and survival in patients after esophageal cancer resection who survived to hospital discharge. Design:Prospective study. Setting:Medical center. Patients:The study population consisted of 109 patients undergoing a transthoracic resection for adenocarcinoma of the middistal esophagus or gastric cardia between April 1994 and February 2000. Interventions:None. Measurements and Main Results:A comparison was made between patients staying ≤5 days vs. ≥6 days in the intensive care unit and also ≤2 days vs. ≥14 days. Quality of life was assessed in all patients by mailed self-report questionnaires at baseline (preoperatively), at 5 wks, and at 3, 6, 9, 12, 18, 24, 30, and 36 months after surgery. Daily physical, emotional, and social functioning was assessed with the generic Medical Outcome Studies Short Form-20. Disease-specific quality of life was measured by an adapted Rotterdam Symptom Check List. Quality of life data were gathered between July 1994 and March 2003. Five of the 109 patients died in the hospital and were excluded from the analysis. All five of them were in the intensive care unit ≥6 days. Of the remaining 104 patients, 92 provided baseline scores. The data of the 92 patients were used for the quality of life analyses. For the clinicopathologic and survival analysis, the data of 104 hospital survivors were used. Patients spent a median of 5.5 days (range 0–71) in the intensive care unit. The Medical Outcome Studies Short Form-20 and the Rotterdam Symptom Check List measurements showed no clear differences in long-term quality of life between patients after a short vs. a prolonged postoperative intensive care unit period. The median overall survival in all patients was 2.0 yrs (range 0.1–8.0). Median overall survival in patients staying in the intensive care unit ≤5 days was 1.9 yrs (range 0.3–7.4 yrs) vs. 2.7 yrs (range 0.9–7.2 yrs) in patients staying ≥6 days (p = .9, log-rank test). Median overall survival in patients staying in the intensive care unit ≤2 days was 1.7 yrs (range 1.2–2.6 yrs) vs. 2.0 yrs (range 0.2–3.8 yrs) in patients staying ≥14 days (p = .74, log-rank test). Conclusions:For patients who survived to hospital discharge after transthoracic esophagectomy, there was no difference in long-term quality of life or survival between those submitted to the intensive care unit for a short period vs. a long period.

Surgery for unusual histopathologic variants of esophageal neoplasms: a report of 23 cases with emphasis on histopathologic characteristics.

Background: Adenocarcinoma and squamous cell carcinoma are the most frequent pathologic diagnoses with esophageal malignancy. Unusual pathologic variants are encountered in only 1% to 7% of patients, and therefore data evaluating the treatment and survival in this group of esophageal neoplasms are sparse.Methods: To get more insight into the unusual pathologic variants, patients were selected from our computer-assisted database containing data from 426 consecutive patients treated with esophageal resection or enucleation at our institute during 1993 to 2000.Results: Uncommon variants of esophageal neoplasms were encountered in 23 patients (5.3%). The following unusual histopathologic variants were seen: basaloid squamous cell carcinoma (n = 3), small-cell carcinoma (n = 1), leiomyoma (n = 5), gastrointestinal stromal tumor (n = 2), leiomyosarcoma (n = 1), adenosquamous carcinoma (n = 5), carcinosarcoma (n = 4), collision tumor (n = 1), and melanoma (n = 1). Presentation, histopathologic characteristics, treatment, and prognosis are described in reference to the existing literature.Conclusions: Survival data of the unusual pathologic variants seem to be comparable to those of the most frequently encountered neoplasms. Only in case of small-cell carcinoma does there seem to be a definite role for chemotherapy, especially in a multimodality treatment protocol.

Comprehensive Cancer Centre Amsterdam Barrett Advisory Committee: first results

BACKGROUND Treatment and follow-up policy for Barretts oesophagus are dependent on the grade of dysplasia. However, sampling error of random biopsy protocols and subjectivity of pathological grading may hamper endoscopic surveillance. METHODS The Amsterdam Comprehensive Cancer Center Barrett Advisory Committee (BAC) is a regional multidisciplinary consultative working-group, offering revision of pathology, revision of pathology plus additional endoscopic diagnostics, or referral for treatment. RESULTS Between July 1998 and July 1999 30 patients were referred to the B.A.C for advice; eighteen patients were referred because of suspicion of high grade dysplasia. Reassessment of biopsies, including additional quantitative pathology, with or without additional endoscopic diagnostics, led to adjustment of the grading of dysplasia in 15 patients (50%). A suspicion of low grade dysplasia was rejected in nine out of ten cases. Adjustment of the original diagnosis often influenced further therapy or follow-up. CONCLUSIONS reassessment of conventional pathology, quantitative pathology, and additional diagnostic procedures might improve the accuracy of diagnosis and staging of malignant degeneration of Barretts oesophagus, although experience is still limited. The complexity of the management of these patients demands a specialised multidisciplinary approach. A Barrett Advisory Committee can offer valuable contributions to the treatment of patients with Barretts oesophagus.

Positive peritruncal nodes for esophageal carcinoma. not always a dismal prognosis.

Background/Aims: For esophageal carcinoma, positive truncal nodes are considered distant metastases, and might be a contraindication for potentially curative surgery. With the development of new diagnostic tools more/smaller peritruncal nodes may be found positive preoperatively. We evaluate whether it is justified to exclude all patients with positive peri-truncal nodes from curative surgery. Methods: Retrospective study of all patients undergoing transhiatal resection for a mid-/distal esophageal carcinoma between 1993 and 1997. Results: 110 patients underwent transhiatal resection for esophageal carcinoma. Sixteen patients had tumor-positive, resectable peritruncal lymph nodes not identified preoperatively, changing preoperative stage III into postoperative stage IV (M1a). After follow-up of 2.9 years (0.07–7.6), 49 patients (45%) were alive. On multivariate analysis radicality and lymph node status were independent prognostic factors. There was no significant difference in survival between stage III and stage IV (M1a) tumors: 1.7 and 1.5 years, respectively (p = 0.87). At the end of follow-up, 4/16 patients (25%) with stage IV (M1a) disease were alive without evidence of disease. Conclusion: The presence of malignant cells in small, resectable peritruncal nodes does not preclude long-term survival. The results of new diagnostic modalities should be interpreted cautiously, until firm criteria for irresectability/incurability of positive truncal nodes are established.

A prospective analysis of patients with adenocarcinoma of the gastric cardia and lymph node metastasis in the proximal field of the chest

BACKGROUND The extent to which adenocarcinoma of the cardia with lymph node metastasis in the upper mediastinum is amenable to cure by radical surgery is open to debate. It remains unclear whether these relatively distant metastases have an effect on long-term survival. The aim of this study was to identify the incidence of such positive nodes and evaluate their prognostic significance. METHODS Some 50 patients with adenocarcinoma of the gastric cardia and substantial invasion of the oesophagus (junctional type II), who underwent an extended transthoracic oesophagectomy as part of a prospective randomized trial between 1994 and 2000, were studied. RESULTS Eleven patients (22 per cent) had lymph node metastasis in the proximal field of the chest. These patients had more positive nodes overall (P = 0.020) and a shorter median survival (P = 0.009) than those without such metastasis. Multivariate analysis identified positive nodes in the proximal field as an independent predictor of poor survival. CONCLUSION Lymph node metastasis in the proximal field of the chest is common and is an indicator of poor prognosis in patients with adenocarcinoma of the cardia.
