What happened, in summary

A 50-year-old woman was receiving treatment for a separate mixed gestational trophoblastic cancer when follow-up imaging showed that several lung nodules had not completely resolved. Because some components of the gestational tumor could resist chemotherapy, her medical team discussed surveillance versus surgical removal. She chose surgery. During right thoracoscopy, surgeons performed wedge resections from two areas of the right lower lobe and one area of the right upper lobe. Most of the removed tissue showed fibrosis and inflammation consistent with treated disease from the other cancer. One right lower lobe specimen, however, contained a 9 mm invasive adenocarcinoma that was TTF-1 positive and napsin A positive, confirming a separate primary lung cancer. The tumor had clear margins and no lymphovascular invasion. It was classified as stage I, pT1a. No additional lung surgery or adjuvant chemotherapy was recommended, and she continued CT surveillance every six months. The report described the lung cancer resection as curative. The patient, who had never smoked, said the second cancer felt deeply unfair and left her more frightened about whether the lung cancer was truly gone and what might happen next.
