Mucoepidermoid carcinoma of the lung presenting as a cavitary lesion.

The authors describe a 62-year-old female patient who presented with a progressively enlarging cavitary lesion in the right upper lobe of the lung. Acid-fast bacilli were recovered from a bronchial washing fluid and identified as Mycobacterium tuberculosis. She received antituberculous therapy for 5 months without improvement in her clinical symptoms and chest radiograph. A lobectomy was performed and pathological review demonstrated a high-grade mucoepidermoid lung carcinoma with extensive central necrosis. Staging revealed metastases in her left adrenal gland, kidney and spine. High-grade mucoepidermoid carcinoma of the lung may present as a cavitary lesion. The presence of M. tuberculosis should not preclude clinicians from pursuing adequate diagnostic procedures for a possible malignant lesion.

The European Organization for Research and Treatment of Cancer quality of life questionnaire: translation and reliability study of the Thai version.

In the past decade, increasing attention is being given to more systematic and quantitative ways to evaluate explicitly the impact of disease and medical interventions on quality of life (QOL). Pertaining to the field of oncology, two relatively new instruments--the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and the FACT-G, have received growing attention and appear to be excellent QOL instruments in clinical settings. FACT-G has already been validated and has been used in Thailand. Thus in the present study, the English version of the EORTC quality of life questionnaire (QLQ-C30) was translated into Thai and the initial descriptive statistic and scale reliability were reported. Mean score in this study of 75 cancer patients was comparable with the original report. Cronbach's alpha coefficient for multi-item scales range from 0.64 to 0.89. The validity of this translated version will be reported at a later date. The initial findings of the present study indicate that the Thai version of the EORTC QLQ-C30 is reliable. A validating process of this version is in progress with active patients accrual ongoing at present.
