Hysterectomy for endometrial cancer. Now have all mediatinal lymph nodes & bilateral hilar enlarged w/virchow's node. No sarcoid. What?

Investigation&biopsy. Need evaluation & investigation , virchow's node is most likely from abdominal metastasis , can be diagnosed by simple biopsy low risk procedure , nature nodes in the chest need pet scan evaluation first or vats ( video assisted thoracic surgery ) biopsy.
Endometrial cancer. It sounds as if there is a recurrence of the endometrial cancer. Need to know stage, grade, histology and extent of original surgery. If recurrence, recommend research protocol versus carboplatin/paclitaxel chemotherapy. If low grade initially, Progesterone or an aromatase inhibitor may be worthwhile instead.
