Arm/Group Title Group 2 (Chemotherapy, Surgery) Group 3 (Chemotherapy, Surgery) Group 4 (Chemotherapy, Surgery, Antineoplastic Therapy) Non-intermediate Risk Enrolled on Intermediate Risk Trial
Hide Arm/Group Description 2 courses of initial chemotherapy (6 wks) - carboplatin, cyclophosphamide, doxorubicin hydrochloride, etoposide, filgrastim. Partial response (PR) to chemo go to observation. No PR: 2-6 additional courses of chemo (beginning course 3 - cyclophosphamide, etoposide, filgrastim, carboplatin, doxorubicin hydrochloride). No PR after additional chemotherapy proceed to retrieval chemo: cyclophosphamide and topotecan hydrochloride on days 1-5. Treatment with retrieval chemotherapy repeats every 21 days for up to 6 courses. Some patients may also undergo surgery. 4 courses of initial chemo - carboplatin, cyclophosphamide, doxorubicin hydrochloride, filgrastim. Patients with a PR after chemo proceed to observation. No PR receive 2-4 additional courses of chemotherapy (beginning with course 5) - carboplatin, cyclophosphamide, doxorubicin hydrochloride, etoposide, filgrastim. No PR after additional chemo proceed to retrieval chemo - cyclophosphamide and topotecan hydrochloride. Some patients may also undergo surgery. 8 courses of initial chemo - carboplatin, cyclophosphamide, doxorubicin hydrochloride, etoposide, filgrastim. Patients < 12 months of age with stg 3, 4, or 4S (not including liver metastases) disease who achieve a very good PR (VGPR) to chemo proceed to observation. Patients 12-18 months of age with stg 3 or 4 who achieve VGPR proceed to isotretinoin therapy. No VGPR proceed to retrieval chemo - cyclophosphamide and topotecan hydrochloride. Some patients may also undergo surgery.

The no treatment group assignment patients may have received some treatment on ANBL0531 but they were not evaluable on this study due to being non-intermediate risk and hence did not receive a treatment assignment on ANBL0531.

Surgery: With the exception of patients with INSS 4S disease, patients undergo surgery to remove as much of the primary tumor and involved lymph nodes as can safely be accomplished.

No PR receive 2-4 additional courses of chemotherapy (beginning with course 5) - carboplatin, cyclophosphamide, doxorubicin hydrochloride, etoposide, filgrastim. No PR after additional chemo proceed to retrieval chemo - cyclophosphamide and topotecan hydrochloride. Some patients may also undergo surgery.

The no treatment group assignment patients may have received some treatment on ANBL0531 but they were not evaluable on this study due to being non-intermediate risk and hence did not receive a treatment assignment on ANBL0531.

Surgery: With the exception of patients with INSS 4S disease, patients undergo surgery to remove as much of the primary tumor and involved lymph nodes as can safely be accomplished.
