A rare case study highlights tumor-to-tumor metastasis, where clear cell renal cell carcinoma metastasizes into lung adenocarcinoma. This finding contributes to the understanding of cancer behavior and potential treatment implications.
This publication presents two case reports of advanced lung adenocarcinoma with complex genetic alterations, including EGFR exon 19 deletion, T790M mutation, STRN::ALK fusion, and EGFR kinase domain duplication. The findings contribute to the understanding of peritoneal metastasis in this cancer subtype.
A case report details an autopsy-confirmed giant pleural hematoma resulting from spontaneous hemothorax in a patient with ALK-rearranged and TP53-mutant lung adenocarcinoma. This study contributes to the understanding of complications associated with specific genetic mutations in lung cancer.
