The majority of patients with non-small cell lung cancer (NSCLC) present with advanced disease, which is associated with a poor prognosis and symptoms such as pain, coughing, and shortness of breath. In patients who present at an earlier stage, the progressive nature of NSCLC and its resistance to treatment often result in recurrence, with the associated symptoms of advanced disease. These symptoms negatively affect patient quality of life and performance status rating, both of which are predictive of treatment response and survival. There is increasing interest in using assessments of improvements in symptoms and quality of life as outcomes in clinical trials for patients with advanced NSCLC. Patients with NSCLC have limited therapeutic options. Even those patients who are able to tolerate chemotherapy can expect median survival increases of only 2 to 4 months. The new targeted therapies for lung cancer, in contrast, are relatively nontoxic and may provide benefits for symptoms and quality of life in addition to tumor responses. The Functional Assessment of Cancer Therapy-Lung (FACT-L) scale is a validated, sensitive, and reliable patient questionnaire that evaluates and quantifies quality of life across several dimensions, including lung cancer-related symptoms (Lung Cancer Subscale). The Lung Cancer Subscale ranges from 0 (severe debilitation) to 28 (asymptomatic). A change of two points reflects a clinically significant change in NSCLC-related symptoms and quality of life. In phase I studies and also in the Iressa Dose Evaluation in Advanced Lung Cancer (IDEAL)-1 and IDEAL-2 phase II monotherapy trials, treatment of patients with advanced NSCLC with the epidermal growth factor receptor-tyrosine kinase inhibitor ZD1839 (Iressa; AstraZeneca Pharmaceuticals LP, Wilmington, DE) has shown tumor responses as well as rapid improvements in NSCLC-related symptoms and quality of life. In IDEAL-1 and IDEAL-2, improvements in NSCLC-related symptoms and quality of life, as measured by FACT-L, correlated with tumor response, and improvements in symptoms also correlated with progression-free and overall survival. Although symptom response is correlated with tumor response, it is also uniquely predictive of progression-free and overall survival. The FACT-L questionnaire has also been included in phase III trials of ZD1839 treatment in combination with chemotherapy regimens.

Gefitinib is a newly developed molecular-target drug with selective inhibitory activity for tyrosine kinase of the epidermal growth factor receptor and has an encouraging effect on non-small cell lung cancer in an advanced stage. The adverse drug reactions including diarrhea, skin eruptions and liver dysfunction have been considered mild. However, cases of severe acute lung injuries were reported after approval of the drug in Japan in July, 2002. We report a case of recurrent large cell carcinoma of the lung in a 73-year-old man who suffered from radiation recall pneumonitis induced by Gefitinib. Two months after radiation therapy to the mediastinal and right hilar lesions was completed, he started to take Gefitinib at a dose of 250 mg/day. Six weeks later, he complained acutely of a dry cough, slight fever and effort dyspnea, and his chest CT demonstrated ground-glass opacity corresponding to the previous radiation field. In administering Gefitinib, as well as other cytotoxic drugs, meticulous monitoring for acute lung injury and radiation recall reaction is required.

Hypertrophic osteoarthropathy is an important manifestation of lung carcinoma, particularly in a non-small cell tumor, and hampers quality of life. Although removal of the primary tumor usually resolves this syndrome, effective treatment in patients with advanced lung carcinoma has not been established. Recently, an orally active, selective epidermal growth factor receptor tyrosine kinase (EGFR) inhibitor ("Gefitinib") provided clinical anti-tumor activity. We describe a 71-year-old male smoker with cough, who presented with clubbed fingers. A transbronchial lung biopsy (stage T2N3M1-IV) on a cavity lesion in the left lower lobe showed the features of adenocarcinoma, while bone scintigram revealed bilaterally symmetrical abnormal uptakes in the lower extremities, suggesting secondary hypertrophic osteoarthropathy. The serum level of growth hormone was increased to 1.42 ng/ml. Chemotherapy (cisplatin, vinorelbine) was not effective. Gefitinib, as a second-line therapy, induced disappearance of the abnormal accumulation on bone scintigraphy and decrease of the cavity in the lung and of serum growth hormone. The presented case suggests that the EGFR inhibitor might be a promising option for the treatment of hypertrophic osteoarthropathy with advanced lung adenocarcinoma.

A 70-year-old woman with cough was diagnosed with pulmonary adenocarcinoma by bronchoscopic transbronchial biopsy. She was diagnosed cT2N0M0, stage IB clinically, and the tumor was surgically resected. Postoperative pathology was confirmed to be pleomorphic carcinoma of pT2N2M0, stage III A. She received 6 courses of adjuvant chemotherapy consisting of cisplatin and docetaxel. Five months later, new pulmonary and bone metastases were detected. Gefitinib was started, and she has shown stable disease for 7 months. Epidermal growth factor receptor (EGFR) mutation was observed in her tumor specimens.
