RATIONALE: Drugs used in chemotherapy, such as etoposide, carboplatin, and bleomycin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving chemotherapy drugs before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving combination chemotherapy after surgery may kill any tumor cells that remain.
