A few lymph nodes in the left axilla are enlarged, suspecting metastasis. Pleural effusion on the left. Osteolytic lesions are found in the left humerus and scapula, suspecting bone metastasis. No obvious abnormalities in the visualized upper abdomen. Subcutaneous nodules in the chest and back are observed, suspecting benign nodules such as sebaceous cysts.",T4,N0,M1c47115654062,"An irregular tumor mass of 46 mm is located in the apex of the right lung, suggesting lung cancer. It is widely in contact with the pleura, and there is a possibility of infiltration.472Bronchiectases in the left upper lobe.473Enlarged lymph nodes in the mediastinum, suggesting metastasis.474There is no pleural effusion.475There is a tumor in the left adrenal region, with an increased density of the surrounding fat tissue. Differential diagnoses include metastasis and hematoma.",T2b,N2,M1b47615702092,"There is a large tumor with a diameter of 12 cm in the left upper lobe of the lung, which is believed to be a known primary lesion. Mediastinal infiltration is suspected. There are also two small nodules around it. Lung cancer with intra-lobe metastasis is suggested.477Left mediastinal lymph node metastasis is suspected. No coarse lesions in the upper abdomen.",T4,N2,M047815853567,"Emphysematous changes.479A tumor mass of 40 mm is found in the right lower lobe. Lung cancer is suspected.480Ground-glass opacities are scattered in the right upper lobe, possibly inflammatory changes, recommended to follow up.481No significant lymph node enlargement in the mediastinum.482There is no pleural effusion.483Hypodense tumors are scattered in the liver, and multiple liver metastases are suspected.484Gallstones.485Common bile duct stones, accompanied by bile duct dilation.486A cyst is found in the left kidney.487No significant lymph node enlargement in the periaortic region.488There is ascites in the pelvic region.",T2a,N0,M1c48916564891,"A nodule is present in the right hilum to the right bronchus (the nodular part is approximately 17 mm). Primary bronchial carcinoma (adenosquamous carcinoma) originating from the right hilum bronchus is suspected. The ventilation of the right lower and middle lobes is decreased, and air bronchograms and mucus plugs are also observed, considered to be an obstructive atelectasis of the right lower and middle lobes due to bronchial carcinoma. The ventilation of the right upper lobe is normal.490No obvious nodules in the left lung.491The right hilar lymph nodes are conglomerated, and lymph node metastasis is suspected. The mediastinal lymph nodes are also enlarged, suggesting metastasis.",T2a,N2,M049216573882,"Mild emphysematous changes.493There is a 12 mm subpleural nodule in the right lower lobe, considered to be the indicated lung cancer lesion.494No significant lymph node enlargement in the mediastinum.495There is no pleural effusion.",T1b,N0,M049616625166,"A tumorous lesion accompanied by a atelectatic lung is observed in the left upper lobe, suggesting to be a finding of known lung cancer. Infiltration into the pleura and mediastinum is suspected. The hilar lymph nodes appear enlarged, indicating a possibility of metastasis.",T4,N1,M0497
