Abstract

OBJECTIVE:

The survival of cervix cancer patients is associated with their hemoglobin (Hgb) level during radiotherapy. The Southwest Oncology Group (SWOG) conducted a phase II trial to determine whether recombinant human erythropoietin (rHuEPO) safely corrects anemia during chemoradiotherapy for cervix cancer.

METHODS:

Patients had stage IIB-IVA cervix cancer and a Hgb between 8.0 and 12.5 g/dl. All patients received rHuEPO thrice weekly and oral iron starting 10-15 days before their 5-week course of whole pelvic irradiation and weekly cisplatin followed by intracavitary brachytherapy.

RESULTS:

Fifty-three patients from 26 institutions received the protocol treatment. The mean Hgb was 10.4 +/- 1.3 g/dl on the first day of rHuEPO administration (baseline), 11.0 +/- 1.6 g/dl on the first day of chemoradiotherapy, 11.6 +/- 1.9 g/dl at the midpoint of chemoradiotherapy, and 11.8 +/- 2.2 g/dl at the end of chemoradiotherapy. The target Hgb level of 12.5 g/dl was achieved in 40% of patients (95% CI 26-56%) by the midpoint of Chemoradiotheraphy. Change in Hgb was associated with baseline serum iron (P = 0.008) and transferrin saturation (P = 0.05) levels, but not with baseline Hgb or serum ferritin, or patient age. Seven patients developed deep vein thrombosis. Two-year progression-free survival (PFS) was 43% and overall survival (OS) was 51%. Survival was significantly associated with Hgb level at the end of chemoradiotherapy, but not with the baseline Hgb level.

CONCLUSIONS:

rHuEPO and iron gradually increased Hgb levels in anemic women with local advanced cervix cancer during chemoradiotherapy. There was a higher than expected incidence of deep vein thrombosis. The progression-free and overall survival rates were lower than reported for women with normal Hgb levels.
