Multiple primary malignant neoplasms (MPMNs) are generally defined as the co-occurrence of primary neoplasms of distinct histology in the same individual. Second and higher-order primary malignancies now comprise about 18% of all cancer incidence in the United States. Specifically in female cancer survivors, the incidence ratio of developing multiple primary cancers (MPCs) is 1.2 to 1.6. Patients with lung cancer are at higher risk to develop a second malignancy compared to the general population. However, the coexistence of non-small cell lung adenocarcinoma and primary hepatocellular carcinoma (HCC) is not described in the literature. Here we describe a rare case of a 69-year-old female with non-small cell lung adenocarcinoma with vertebral metastasis that developed primary HCC.
Keywords: hepatocellular carcinoma (hcc); multiple primary malignant neoplasm; multiple primary neoplasms; next generation sequencing (ngs); non-small cell lung carcinoma (nsclc); transarterial embolization.
