The value of plain chest radiography in the diagnosis of primary hepatocellular cancer (PHC) was assessed in 449 patients. An elevated right hemidiaphragm and pulmonary metastases were present in 11% and strongly suggest a diagnosis of PHC. In all, the right hemidiaphragm was raised in 30% of patients. Pulmonary metastases were present on admission in 19% of patients and appeared later in a further 6%. Secondary deposits were found in the lungs at necropsy in 52% of patients, compared with only 24% in whom there was radiological evidence of metastases during life. In 36% of patients chest radiographs were normal on admission.
对449例原发性肝细胞癌（PHC）患者进行了胸部平片在诊断中的价值评估。11%的患者出现右侧膈肌抬高和肺转移，强烈提示PHC诊断。总体而言，30%的患者右侧膈肌抬高。19%的患者入院时即有肺转移，另有6%随后出现。尸检时52%的患者肺部发现继发性病灶，而生前有放射学转移证据的仅为24%。36%的患者入院时胸部X线片正常。
