The European Organization for Research and Treatment of Cancer (EORTC) Quality-of-Life questionnaire cervical cancer module: EORTC QLQ-CX24.

The authors report on the development and validation of a cervical cancer module for the European Organization for Research and Treatment of Cancer (EORTC) Quality‐of‐Life (QoL) questionnaire (QLQ), which was designed to assess disease‐specific and treatment‐specific aspects of QoL in patients with cervical cancer.

Clinical and psychometric validation of the EORTC QLQ-CR29 questionnaire module to assess health-related quality of life in patients with colorectal cancer

This international study aimed to test the measurement properties of the updated European Organisation for Research and Treatment of Cancer (EORTC) questionnaire module for colorectal cancer, the QLQ-CR29. The QLQ-CR29 was administered with the QLQ-C30, core questionnaire, to 351 patients from seven countries. Questionnaire scaling and reliability were established and clinical and psychometric validity examined. Patient acceptability and understanding were assessed with a debriefing questionnaire. Multi-trait scaling analyses and face validity refined the module to four scales assessing urinary frequency, faecal seepage, stool consistency and body image and single items assessing other common problems following treatment for colorectal cancer. Scales distinguished between clinically distinct groups of patients and did not correlate with QLQ-C30 scales, demonstrating construct validity. The QLQ-CR29 scores were reproducible over time in stable health. The EORTC QLQ-CR29 demonstrates sufficient validity and reliability to support its use to supplement the EORTC QLQ-C30 to assess patient-reported outcomes during treatment for colorectal cancer in clinical trials and other settings.

Better Prediction of Prognosis for Patients with Nasopharyngeal Carcinoma Using Primary Tumor Volume

Heterogeneity of primary tumor volume within tumors of the same classification indicates a need to elucidate the effects of primary tumor volume on treatment outcomes in patients with nasopharyngeal carcinoma (NPC).

Quality of life of lung cancer patients: Validation of the Taiwan Chinese version of the EORTC QLQ-C30 and QLQ-LC13

The purpose of this study was to test the validity and reliability of the Taiwan Chinese translation of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (EORTC QLQ-C30, version 3) and Quality of Life Questionnaire Lung Cancer-13 (QLQ-LC13) questionnaires. Consecutively 51 patients with lung cancer undergoing active chemotherapy and 48 such patients undergoing regular follow-up completed the questionnaires. The intraclass correlation between test and retest ranged from 0.46 to 0.85 for the QLQ-C30 and was 0.76 for dyspnea for the QLQ-LC13. The κ coefficients between test and retest ranged from 0.51 to 0.73 for single items of the QLQ-C30 and 0.49–0.68 for five of the nine items in the QLQ-LC13. The Cronbachs α coefficients were ≥ 0.70 for all scales of the two questionnaires apart from that of cognitive functioning. The correlation coefficients between indices measuring similar dimensions of the EORTC QLQ-C30 and the SF-36 questionnaires ranged from 0.43 to 0.73, and that between the dyspnea scales of the two EORTC questionnaires was 0.70. Patients in the follow-up group revealed higher scores of global status/quality of life, and lower scores of nausea/vomiting, as also physical functioning. The questionnaires could also detect expected adverse effects of radiotherapy, cisplatin, and paclitaxel.

Quality of life in patients of nasopharyngeal carcinoma: Validation of the Taiwan Chinese version of the EORTC QLQ-C30 and the EORTC QLQ-H&N35

The authors followed the guidelines of translation and pilot testing of the EORTC QLQ-C30 and EORTC-QLQ-H&N35 questionnaires. The questionnaires were given to 50 nasopharyngeal carcinoma patients under active treatment and 50 under follow-up at our institution from November 2000 to June 2001. A retest was conducted 2 weeks after the first interview/form completion for the follow-up group. The intraclass correlation coefficients of the two questionnaires were moderate to high in the follow-up group. Cronbachs α coefficients of all scales of the two questionnaires were ≥ 0.70 except that of cognitive functioning. Correlation of scales measuring similar dimensions of the QLQ-C30 and the SF-36 were moderate to high, while that of the QLQ-H&N35 and the QLQ-C30 and the SF-36 were moderate to low. Patients in the active treatment group had more serious acute problems due to disease and chemotherapy. Patients in the follow-up group had more serious chronic problems due to radiation therapy. We concluded that the Taiwan Chinese version of the EORTC QLQ-C30 and the EORTC QLQ-H&N35 had moderate to high test–retest reliability, high internal consistency in most scales, and could show the expected differences between patients in active treatment and follow-up group.

Prevalence of and Risk Factors for Colonization by Methicillin-Resistant Staphylococcus aureus among Adults in Community Settings in Taiwan

ABSTRACT In order to determine the prevalence of methicillin (meticillin)-resistant Staphylococcus aureus (MRSA) colonization among adults in community settings in Taiwan and identify its risk factors, we conducted the present study. For a 3-month period, we enrolled all adults who attended mandatory health examinations at three medical centers and signed the informed consent. Nasal swabs were taken for the isolation of S. aureus. For each MRSA isolate, we performed multilocus sequence typing, identification of the staphylococcal cassette chromosome mec, tests for the presence of the Panton-Valentine leukocidin gene, and tests for drug susceptibilities. Risk factors for MRSA colonization were determined. The results indicated that the MRSA colonization rate among adults in the community settings in Taiwan was 3.8% (119/3,098). Most MRSA isolates belonged to sequence type 59 (84.0%). Independent risk factors for MRSA colonization included the presence of household members less than 7 years old (P < 0.0001) and the use of antibiotics within the past year (P = 0.0031). Smoking appeared to be protective against MRSA colonization (P < 0.0001).

Quality of life impact and treatment seeking of Chinese women with urinary incontinence

The objective of this study was to investigate the quality of life (QOL) impact of urinary incontinence (UI) and to examine its relationship with treatment seeking in adult Taiwanese women. We conducted a cross-section in-person questionnaire interview of 1608 adult women living in the Taipei area. The characteristics and incontinence status were recorded. A short form incontinence impact questionnaire (IIQ-7) was used to evaluate the QOL impact of UI. Multiple logistic regression analysis was used to assess the determinative factors for treatment seeking. The mean IIQ-7 score of the 205 (12.7%) women who reported urinary leakage more than once per month in the preceding 12 months was 5.0 (range: 0–19), which showed a significant correlation with the severity of incontinence (r = 0.59, p < 0.001). Women with mixed type UI had a higher IIQ-7 score compared to those with stress or urge UI. Fifty-five (26.8%) incontinent women had sought medical help. Treatment seeking was highly related to IIQ-7 scores as 75% of incontinent women with an IIQ-7 score > 10 in contrast to 5% of those with an IIQ-7 score ≤ (p < 0.001) had sought medical care. On multiple logistic regression analysis, perceiving UI as a disease and a higher IIQ-7 score were independent factors predicting treatment seeking. We concluded that UI is a common problem that brings substantial QOL impact to Taiwanese women. The IIQ-7 questionnaire may provide a useful measurement to quantitate the degree of QOL impact, which is largely affected by the severity and type of incontinence. Women who perceive UI as a disease and those with a higher degree of QOL impact are more likely to seek medical help. Furthermore, treatment seeking in Taiwanese women with significant UI may be more common than thought as a great majority of women with higher IIQ-7 scores had sought medical help.

International field testing of the reliability and validity of the EORTC QLQ‐BM22 module to assess health‐related quality of life in patients with bone metastases

Psychometric validation of the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Endometrial Cancer Module (EORTC QLQ-EN24).

AIM A validation study was conducted to evaluate the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Endometrial Cancer Module (EORTC QLQ-EN24). This module was designed to assess disease and treatment specific aspects of the quality of life (QoL) of patients with endometrial cancer. METHODS Two hundred and sixty-eight women with endometrial cancer were recruited in different phases of treatment: after pelvic surgery (Group 1); during adjuvant chemotherapy and/or radiotherapy (Group 2); after completion of treatment (Group 3). Patients completed the EORTC QLQ-C30, the endometrial cancer module and a short debriefing questionnaire. RESULTS Multi-trait scaling analyses confirmed the hypothesised scale structure of the QLQ-EN24. Internal consistency reliability was good with Cronbachs alpha coefficients ranging from 0.74 to 0.86 (lymphoedema 0.80, urological symptoms 0.75, gastrointestinal symptoms 0.74, body image problems 0.86 and sexual/vaginal problems 0.86). Convergent and discriminant validity did not show any scaling errors for the subscales. The QLQ-EN24 module discriminated well between clinically different groups of patients. All items exhibited a high completion rate with less than 2% missing values except for the sexuality items (19%). CONCLUSION The validation study supports the reliability, the convergent and divergent validity of the EORTC QLQ-EN24. This newly developed QLQ-EN24 module is a useful instrument for the assessment of the QoL in patients treated for endometrial cancer in clinical trials.

Quality of Life After Palliative Radiation Therapy for Patients With Painful Bone Metastases: Results of an International Study Validating the EORTC QLQ-BM22

PURPOSE Radiation therapy (RT) is an effective method of palliating painful bone metastases and can improve function and reduce analgesic requirements. In advanced cancer patients, quality of life (QOL) is the primary outcome of interest over traditional endpoints such as survival. The purpose of our study was to compare bone metastasis-specific QOL scores among patients who responded differently to palliative RT. METHODS AND MATERIALS Patients receiving RT for bone metastases across 6 countries were prospectively enrolled from March 2010-January 2011 in a trial validating the QLQ-BM22 and completed the QLQ-BM22 and the core measure (QLQ-C30) at baseline and after 1 month. Pain scores and analgesic intake were recorded, and response to RT was determined according to the latest published guidelines. The Kruskal-Wallis nonparametric and Wilcoxon rank sum tests compared changes in QOL among response groups. A Bonferroni-adjusted P<.003 indicated statistical significance. RESULTS Of 79 patients who received palliative RT, 59 were assessable. Partial response, pain progression, and indeterminate response were observed in 22, 8, and 29 patients, respectively; there were no patients with a complete response. Patients across all groups had similar baseline QOL scores apart from physical functioning (patients who progressed had better initial functioning). One month after RT, patients who responded had significant improvements in 3 of 4 QLQ-BM22 domains (painful site, P<.0001; painful characteristic, P<.0001; and functional interference, P<.0001) and 3 QLQ-C30 domains (physical functioning, P=.0006; role functioning, P=.0026; and pain, P<.0001). Patients with progression in pain had significantly worse functional interference (P=.0007) and pain (P=.0019). CONCLUSIONS Patients who report pain relief after palliative RT also have better QOL with respect to bone metastasis-specific issues. The QLQ-BM22 and QLQ-C30 are able to discriminate among patients with varying responses and are recommended for use in future bone metastasis clinical trials.
