case_images: A complete response after six cycles of chemotherapy according to the contrast-enhanced chest computed tomography scan.. Notes: Contrast-enhanced chest computed tomography scan showing a mass located in the hilum of the right lung (A). This mass exhibited evident shrinkage following six cycles of chemotherapy (B).

case_images: The patient demonstrated a partial response (PR) after four cycles and a complete response (CR) after six cycles according to the chest CT scan, which showed a streaky or coarse reticular pattern of opacities in the upper right lobe under the pleura and small nodules in the right hilum (Figure 1).
case_images: A stable disease after six additional cycles of chemotherapy according to the contrast-enhanced chest computed tomography scan.. Notes: Enhanced chest computed tomography scan on February 18, 2008, showing lung cancer with mediastinal lymph node metastasis, a right lower lobe lesion, and mediastinal lymph node enlargement (A). The lesion was significantly reduced and remained stable after six additional cycles of chemotherapy (B).

case_images: A potential PR was assessed after cycle 8, and the patient was evaluated after cycle 10 for stable disease (SD) (Figure 2).
case_images: Enhanced brain computed tomography scan showing that erlotinib treatment combined with whole-brain radiation therapy was effective for the patient.. Notes: Enhanced brain computed tomography scan revealing metastasis in the right occipital lobe (A). This metastasis significantly shrank after erlotinib treatment combined with whole-brain radiation therapy until September 2009 (B).

case_images: Oral erlotinib (150 mg/day) was administered from July 2008 to December 2009 (Figure 3).
case_images: Abdominal computed tomography scan showed liver and adrenal metastases, and other lesions did not change significantly.. Notes: Enhanced abdominal computed tomography scan showing liver and adrenal metastases (A, D). A brain magnetic resonance image revealed abnormal enhancement in nodules of the right occipital lobe with a history of suspected metastases and a right cerebellar lesion without abnormal enhancement (B). An enhanced chest computed tomography scan showed no significant change compared to the original film (C).

case_images: Emission CT showed no signs of bone metastases (Figure 4).
case_images: A brain magnetic resonance image and an enhanced abdominal computed tomography showed no significant change from the previous month.. Notes: An enhanced abdominal computed tomography scan revealing multiple liver lesions and right adrenal metastases (A, C). A brain magnetic resonance image showed no significant change from the previous month (B).

case_images: From January 23, 2010 to February 20, 2010, the patient was re-treated according to chemotherapy cycles 3 and 4 using the following medications: 140 mg of docetaxel iv on day 1 and 500 mg of carboplatin iv on day 1 (Figure 5).
case_images: Imaging findings after the patient received maintenance therapy with oral gefitinib.. Notes: A brain magnetic resonance image and an enhanced abdominal computed tomography scan shown in a stable disease (B, C). An enhanced chest computed tomography scan showed no significant change compared to the original film (A).
