Lung Adenocarcinoma with Metachronous Ovarian Metastasis: a long survival case report.

BACKGROUND: Lung adenocarcinoma which invades ovaries is very rare. However, with the increase of long-survival female lung cancer, more patients will suffer ovarian metastasis. On grounds of the paucity of reported cases, the clinicopathological features and treatment strategies remain unknown. CASE PRESENTATION: This patient was stage IV lung adenocarcinoma at first diagnosis. Following multiple-line systemic treatments, she experienced extensive pelvic metastasis. After debulking surgery and reevaluation about the drive genes, she was administered by targeted therapy. Up to now, the patient has shown no evidence of progression for 8 years after the initial diagnosis of primary lung cancer and 46 months after her ovarian metastasis. CONCLUSION: The comprehensive treatment modality for the bilateral ovarian metastasis is effective in clinical course.
