A 53-year-old female with advanced lung adenocarcinoma and a venous thromboembolic event showed significant improvement with sequential ALK inhibitors crizotinib and alectinib. This case highlights effective treatment for ALK-positive lung cancer with metastasis.
Area of Science:
- Oncology
- Pulmonology
- Genetics
Background:
- A 53-year-old female presented with a 4-month history of worsening cough, sputum, and dyspnea on exertion.
- Initial imaging over 2.5 years showed stable pulmonary nodules, followed by significant interval growth and interstitial changes.
Observation:
- The patient experienced a venous thromboembolic event (VTE) with elevated D-dimer upon admission.
- Diagnostic workup included bronchoscopy, gastroscope, PET-CT, and MRI, revealing lung adenocarcinoma with extensive metastasis.
Findings:
- Pathological diagnosis confirmed lung adenocarcinoma (solid, mucus-secreting) with mediastinal, hilar, intrapulmonary, and gastric metastasis.
- Genetic analysis revealed a positive EML4-ALK fusion gene in both lung and stomach tissues.
- The patient responded well to sequential treatment with crizotinib and alectinib, along with anticoagulation.
Implications:
- This case demonstrates the efficacy of sequential ALK tyrosine kinase inhibitors in managing advanced, metastatic ALK-positive lung adenocarcinoma.
- Early detection and management of VTE are crucial in patients with advanced lung cancer.
- Targeted therapy offers a favorable prognosis, maintaining quality of life for patients with complex oncological presentations.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
