Background: Metastasis to oral soft tissues is rare and account for only 0.1% of all oral malignancies. Oral cavity metastasis tends to be male-predominant, and lung cancer is the leading cause. Targeted therapies for advanced ALK rearranged non-small cell lung cancer (NSCLC) have shown a promising higher response than cytotoxic chemotherapy. Gingival metastasis usually shows poor prognosis. However using ALK inhibitor to ALK-positive advanced NSCLC may show longer survival. Case: A 64-year-old male who was diagnosed non-small cell carcinoma (NSCC) favoring adenocarcinoma presented with gingival metastasis. After first-line chemotherapy, ALK rearrangement was revealed in both primary lesion and gingival metastasis, and therefore the patient was treated with alectinib. Tumor response of the primary site and gingival lesion were obtained, however he presented with intestinal metastasis that lead to bowel obstruction and passed away. Conclusion: Our case showed good response to primary tumor and gingival metastasis but not to intestinal obstruction. ALK inhibitor often shows high response rate and long survival for ALK rearrangement NSCLC, however ALK rearranged positive NSCLC with gingival metastasis may have poor prognosis. |
