Overview

Case report shows spontaneous regression of lung adenocarcinoma in an elderly female, suggesting potential immunological mechanisms.

Key Points

  • To present a rare case of spontaneous regression of metastatic lung adenocarcinoma post-biopsy without treatment.
  • Case report of a 70-year-old female with metastatic adenocarcinoma diagnosed via EBUS histology.
  • Follow-up scans were conducted over a year after deciding against anticancer treatment.
  • Imaging analyzed included PET CT before and after the regression.
  • A dramatic reduction of the cavitary lung lesion from 20mm to 5mm with no metastatic signs was observed after one year.
  • Patient maintained functional fitness without anticancer therapy.
  • Hypotheses suggest immunologic mechanisms may have played a role in regression.
