Treatment course, step by step

  1. She started ensartinib for unresectable Stage III lung cancer.
  2. After 12 weeks, the tumor had shrunk by 78% and became operable.
  3. She underwent right upper lobectomy with lymph-node removal, and no residual cancer was found.
  4. She continued ensartinib after surgery.

What happened, in summary

A 65-year-old woman was hospitalized with right-sided chest pain in May 2024. A biopsy of a right upper-lung lesion confirmed squamous cell lung cancer. The cancer was Stage III and was considered unresectable at diagnosis. Testing found an ALK rearrangement and high PD-L1 expression.

She started the targeted therapy ensartinib. A rash and liver-test changes led to a temporary dose adjustment, but she was able to continue treatment. After 12 weeks, the tumor had shrunk by 78%, a partial response that changed the treatment options available to her.

The cancer was reassessed as operable, and in August 2024 she underwent minimally invasive right upper lobectomy with lymph-node removal. Pathology found no remaining cancer cells in the lung tumor bed, lymph nodes, surgical margins, or bronchial stump, representing a complete pathologic response.

She continued ensartinib after surgery. Follow-up chest scans at 8 months and again at 15 months showed no recurrence.
