fludeoxyglucose f 18-pet/ct imaging in assessing response to chemotherapy in patients with newly diagnosed stage ii, stage iii, or stage iv hodgkin lymphoma

Conditions: Lymphoma

Summary: rationale: imaging procedures, such as fludeoxyglucose f 18 (fdg)-pet/ct scan, done before, during, and after chemotherapy may help doctors assess a patient's response to treatment and help plan the best treatment. it is not yet known whether fdg-pet/ct imaging is effective in assessing response to chemotherapy in patients with newly diagnosed hodgkin lymphoma. purpose: this randomized phase iii trial is studying fdg-pet/ct imaging to see how well it works in assessing response to chemotherapy in patients with newly diagnosed stage ii, stage iii, or stage iv hodgkin lymphoma.

objectives: * to determine if fludeoxyglucose f 18 (fdg)-pet/ct imaging can be reproducibly and effectively applied in the early assessment of response to chemotherapy in patients with newly diagnosed stage ii-iv hodgkin lymphoma. * to determine if a negative fdg-pet/ct scan after 2 courses of abvd chemotherapy comprising doxorubicin hydrochloride, bleomycin, vinblastine, and dacarbazine can be used to predict a group of patients for whom it is safe to reduce therapy by the subsequent omission of bleomycin, without detriment to progression-free survival. * to determine if treatment intensification in response to positive fdg-pet/ct imaging after 2 courses of abvd chemotherapy can improve the outcome by comparison with previous series. outline: this is a multicenter study. patients undergo fludeoxyglucose f 18 (fdg)-pet/ct imaging at baseline. patients then receive abvd chemotherapy comprising doxorubicin hydrochloride iv, bleomycin iv, vinblastine iv, and dacarbazine iv on days 1 and 15. treatment repeats every 28 days for up to 2 courses in the absence of disease progression or unacceptable toxicity. between days 22 and 25 of course 2, patients undergo a second fdg-pet/ct scan to assess response. subsequent therapy is based on fdg-pet/ct scan results. * negative fdg-pet/ct scan: patients with a negative fdg-pet/ct scan are randomized to 1 of 2 treatment arms. * arm i (abvd chemotherapy): patients receive abvd chemotherapy comprising doxorubicin hydrochloride iv, bleomycin iv, vinblastine iv, and dacarbazine iv on days 1 and 15. treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. * arm ii (avd chemotherapy): patients receive avd chemotherapy comprising doxorubicin hydrochloride iv, vinblastine iv, and dacarbazine iv on days 1 and 15. treatment repeats every 28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. * positive fdg-pet/ct scan: patients with a positive fdg-pet/ct scan are assigned to 1 of 2 chemotherapy regimens, as determined by the participating center. * beacopp-14 chemotherapy: patients receive doxorubicin hydrochloride iv and cyclophosphamide iv on day 1; etoposide iv on days 1-3; oral procarbazine hydrochloride and oral prednisolone on days 1-7; and bleomycin iv and vincristine iv on day 8. patients also receive filgrastim (g-csf) subcutaneously (sc) on days 8-13 or pegfilgrastim sc once on day 8. treatment repeats every 14 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. * beacopp-escalated chemotherapy: patients receive doxorubicin hydrochloride iv and cyclophosphamide iv on day 1; etoposide iv on days 1-3; oral procarbazine hydrochloride on days 1-7; oral prednisolone on days 1-14; and bleomycin iv and vincristine iv on day 8. patients also receive g-csf sc beginning on day 8 and continuing until blood counts recover or pegfilgrastim sc once on day 8. treatment repeats every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity. after completion of beacopp chemotherapy, patients undergo a third fdg-pet/ct scan to assess response. patients with a negative fdg-pet/ct scan receive 2 more courses of beacopp-14 or 1 more course of beacopp-escalated chemotherapy. patients with a persistently positive fdg-pet/ct scan may receive radiotherapy to sites of fdg uptake or salvage chemotherapy, at the investigator's discretion. after completion of study therapy, patients are followed every 3 months for 1 year, every 4 months for 2 years, every 6 months for 2 years, and then annually thereafter. peer reviewed and funded or endorsed by cancer research uk.
