Cyclophosphamide and Cryoablation in Treating Patients With Advanced or Metastatic Epithelial Cancer

RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Cryoablation kills cancer cells by freezing them. Giving chemotherapy together with cryoablation may kill more cancer cells.
PURPOSE: This clinical trial is studying how well giving cyclophosphamide together with cryoablation works in treating patients with advanced or metastatic epithelial cancer.
