PURPOSE We aimed to evaluate psychometric properties of the Korean version of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-NMIBC24 when applied to Korean non-muscle invasive bladder cancer (NMIBC) patients. MATERIALS AND METHODS A total of 249 patients who underwent curative transurethral resection of bladder tumor (TURBT) for primary or recurrent NMIBC were aske...

AIM To determine clinical prognostic factors and their impact on the risk of recurrence of newly discovered non-muscle-invasive bladder cancer. METHODS The study included 120 patients of both sexes aged 45-80 years with newly discovered non-muscle-invasive bladder cancer. All the patients were treated surgically by transurethral electro resection (TUER). The outcome of patients with and witho...

BACKGROUND Well-developed and well-tested patient-reported outcome measures for non-muscle-invasive bladder cancer (NMIBC) are required. OBJECTIVE To test and adapt the scale structure and explore the psychometric properties of the European Organisation for Research and Treatment of Cancer (EORTC) questionnaire for NMIBC. DESIGN, SETTING, AND PARTICIPANTS A total of 433 patients in the Blad...

BACKGROUND Quality of life (QL) data are useful to evaluate the effectiveness of treatment. Accumulating evidence suggests that QL data may predict survival. AIMS In this study we investigated if baseline QL scores and changes in QL scores before and after intervention are prognostic for patients with oesophageal cancer. PATIENTS Between 1993 and 1995, 92 consecutive new patients with oesop...

BACKGROUND The use of endocrine therapy (ET) in postmenopausal breast cancer patients may affect their cognitive status. This study aims to assess the effects of tamoxifen and aromatase inhibitors (Als) on quality of life (QoL) and cognitive functions in breast cancer patients. PATIENTS AND METHODS The study included 101 patients receiving tamoxifen, 97 patients receiving Als, and 95 patients...

BACKGROUND The purpose of this study was to compare total laryngectomy versus concurrent chemoradiotherapy (CRT) for functional and long-term quality of life (QOL) outcomes in patients with pharyngolaryngeal carcinoma. METHODS Among 145 patients treated for advanced pharyngolaryngeal cancer by CRT or total laryngectomy between 2000 and 2008, 47 patients who had completed treatment for >1 year...

BACKGROUND This study evaluates the consistency of PET evaluation response criteria in solid tumours (PERCIST) and European Organisation for Research and Treatment of Cancer (EORTC) classification across different reconstruction algorithms and whether aligning standardized uptake values (SUVs) to the European Association of Nuclear Medicine acquisition (EANM)/EARL standards provides more consis...

BACKGROUND Currently, several fatigue measurement instruments are available to evaluate and measure cancer-related fatigue. Amongst them, Multidimensional Fatigue Syndrome Inventory-Short Form (MFSI-SF) is a self-reported instrument and a multidimensional scale that aims to capture the global, somatic, affective, cognitive and behavioural symptoms of fatigue. This study examines the psychometri...

BACKGROUND The symptom burden associated with multiple myeloma (MM) is often severe. Presently, no instrument comprehensively assesses disease-related and treatment-related symptoms in patients with MM. We sought to validate a module of the M. D. Anderson Symptom Inventory (MDASI) developed specifically for patients with MM (MDASI-MM). METHODS The MDASI-MM was developed with clinician input, ...
