Description

Summary

This trial examined the outcome benefit to patients of adding a new chemotherapy drug combination to the established treatment approach for patients with extracranial Ewing sarcoma, that had not spread from the primary site to other places in the body. The trial randomly assigned patients at the time of study entry to receive established standard treatment with the following 5-drugs: vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, ifosfamide and etoposide. The outcome for patients receiving the standard 5-drug combination was compared to the outcome for patients who received the same 5-drugs with an additional drug, topotecan hydrochloride delivered in a novel combination with vincristine sulfate and cyclophosphamide.

Official Title

A Phase III Randomized Trial of Adding Vincristine-Topotecan-Cyclophosphamide to Standard Chemotherapy in Initial Treatment of Non-Metastatic Ewing Sarcoma

Details

PRIMARY OBJECTIVES:

  1. Test the effect of the combination of vincristine (vincristine sulfate), cyclophosphamide, and topotecan (topotecan hydrochloride) (VTC) added to the standard 5-drug interval-compressed chemotherapy backbone on event-free and overall survival of children and young adults with Ewing sarcoma.

CORRELATIVE SCIENCE OBJECTIVES:

  1. To evaluate initial volumetric tumor size as a prognostic factor for event free survival (EFS) in patients with localized Ewing tumors.

II. To evaluate histologic response as a prognostic factor for EFS in patients with localized Ewing tumors.

III. To continue evaluation of biologic markers both as related to prognosis and as eventual therapeutic targets via encouraging concurrent enrollment on a Ewing sarcoma specimen-collection study.

IV. To evaluate imaging response by fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) as a prognostic factor for EFS.

  1. To evaluate the effects of the type of local therapy on EFS and overall survival.

VI. To evaluate the effect of local surgical margins in conjunction with histologic response on EFS in patients with localized Ewing tumors.

VII. To evaluate the effect of local therapy modality (surgery, radiotherapy, or a combination) as well as the type of surgical reconstruction on musculoskeletal complications.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM A:

INDUCTION THERAPY: Patients receive vincristine sulfate intravenously (IV) on day 1 in weeks 1, 2, 5, 6, 9, and 10; doxorubicin hydrochloride IV over 1-15 minutes (or as per institutional policies up to 60-minutes) on days 1 and 2 and cyclophosphamide IV over 30-60 minutes on day 1 in weeks 1, 5, and 9; and ifosfamide IV over 1 hour and etoposide IV over 1-2 hours on days 1-5 in weeks 3, 7, and 11.

CONSOLIDATION THERAPY: Patients receive vincristine sulfate IV on day 1 in weeks 1, 2, 7, 8, 9, 10, 13, 14, 17, 18, 21, and 22; doxorubicin hydrochloride IV on days 1 and 2 in weeks 1 and 9; cyclophosphamide IV over 30-60 minutes on day 1 in weeks 1, 7, 9, 13, 17, and 21; and ifosfamide IV over 1 hour and etoposide IV over 1-2 hours on days 1-5 in weeks 3, 5, 11, 15, and 19. Patients received Dexrazoxane with doxorubicin hydrochloride in weeks 1 and 9.

ARM B:

INDUCTION THERAPY: Patients receive vincristine sulfate IV on day 1 in weeks 1, 2, 5, 6, 9, 10, 11 and 12; topotecan hydrochloride IV over 30 minutes on days 1-5 in weeks 1 and 9; cyclophosphamide IV over 15-30 minutes on days 1-5 in weeks 1 and 9, and over 30-60 minutes on day 1 of weeks 5 and 11; ifosfamide and etoposide as in arm A; and doxorubicin hydrochloride IV on days 1 and 2 in weeks 5 and 11.

CONSOLIDATION THERAPY: Patients receive vincristine sulfate IV on day 1 in weeks 1, 2, 7-10, 13-16, 19, and 20; topotecan hydrochloride IV over 30 minutes on days 1-5 in weeks 1, 7, and 15; cyclophosphamide IV over 15-60 minutes on days 1-5 in weeks 1, 7, and 15, and over 30-60 minutes on day 1 in weeks 9, 13, and 19; ifosfamide IV over 1 hour and etoposide IV over 1- 2 hours on days 1-5 in weeks 3, 5, 11, 17, and 21; and doxorubicin hydrochloride IV on days 1 and 2 in weeks 9,13, and 19. Patients received Dexrazoxane with doxorubicin hydrochloride in weeks 13 and 19.

Patients could undergo surgery alone after recovery from week 12 chemotherapy if the primary tumor could be completely resected with negative margins and with reasonable functional result. Patients with inadequate margins after surgery were to receive radiotherapy in addition. Patients with lesions in surgically difficult sites such as the spine, skull, and periacetabular pelvis, patients with a poor response to induction chemotherapy, or those patients in whom surgery would result in unacceptable functional results were recommended to receive radiation and not surgery. Radiotherapy was to be administered during weeks 1-7 of consolidation therapy or after recovery from surgery for patients with positive margins. Patients who received planned pre-operative radiation and had positive surgical margins were to receive additional radiotherapy.

After completion of study therapy, patients are followed up every 3 months for 3 years and then every 6 months for 2 years.

Eligibility

You can join if…

Open to people ages up to 50 years

  • Patients with newly diagnosed, biopsy confirmed, extracranial, non-metastatic Ewing sarcoma or primitive neuroectodermal tumor (PNET) of bone or soft tissue are eligible for this study; note:
    • For the purpose of this study, chest wall tumors with ipsilateral pleural effusions, ipsilateral positive pleural fluid cytology or ipsilateral pleural based secondary tumor nodules will be considered localized disease
    • Patients with regional node involvement, based on clinical suspicion confirmed by pathologic documentation are considered to be non-metastatic
    • Patients with discontinuous osseous lesions within the same bone are considered to be non-metastatic
    • Tumors arising in the bony skull (extra-dural) are considered to be extracranial
  • Patient eligibility will be based on a diagnosis of Ewing sarcoma or PNET by institutional pathologist
  • No prior chemotherapy or radiation therapy is allowed; patients should only have had a biopsy of the primary tumor without an attempt at complete or partial resection; patients will still be eligible if unplanned excision was attempted or accomplished as long as adequate imaging was obtained prior to surgery

    • Distant lymph node involvement
    • Patients with pulmonary nodules are considered to have metastatic disease if the patient has:
      • Solitary nodule > 0.5 cm or multiple nodules of > 0.3 cm unless biopsied and negative for Ewing's
      • Biopsies of solitary nodule =< 0.5 cm or multiple nodules =< 0.3 cm are not required but if performed and positive indicate metastatic disease
  • Patients whose tumors arise in the dural and intra-dural soft tissues of the cranium and spine are not eligible
  • Patients with pathologic diagnoses other than Ewing sarcoma will be excluded
  • Patients diagnosed with Ewing Sarcoma as a second malignant neoplasm are not eligible if they have received chemotherapy or radiation for the treatment of their primary malignancy
  • Pregnant women will not be entered on this study; pregnancy tests must be obtained in female patients who are post-menarchal; lactating females may not participate unless they have agreed not to breastfeed their infants; males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method for the duration of the study treatment
  • All patients and/or their parents or legal guardians must sign a written informed consent
  • All institutional, Food and Drug Administration (FDA), and National Cancer Institute (NCI) requirements for human studies must be met
