Abstract

Purpose: Adjuvant pegylated interferon alfa-2b (PEG-IFN-α-2b) was approved for treatment of resected stage III melanoma in 2011. Here, we present long-term follow-up results of this pivotal trial. Patients and Methods: In all, 1,256 patients with resected stage III melanoma were randomly assigned to observation (n = 629) or PEG-IFN-α-2b (n = 627) for an intended duration of 5 years. Stratification factors were microscopic (N1) versus macroscopic (N2) nodal involvement, number of positive nodes, ulceration and tumor thickness, sex, and center. Recurrence-free survival (RFS; primary end point), distant metastasis-free survival (DMFS), and overall survival (OS) were analyzed for the intent-to-treat population. Results: At 7.6 years median follow-up, 384 recurrences or deaths had occurred with PEG-IFN-α-2b versus 406 in the observation group (hazard ratio [HR], 0.87; 95% CI, 0.76 to 1.00; P = .055); 7-year RFS rate was 39.1% versus 34.6%. There was no difference in OS (P = .57). In stage III-N1 ulcerated melanoma, RFS (HR, 0.72; 99% CI, 0.46 to 1.13; P = .06), DMFS (HR, 0.65; 99% CI, 0.41 to 1.04; P = .02), and OS (HR, 0.59; 99% CI, 0.35 to 0.97; P = .006) were prolonged with PEG-IFN-α-2b. PEG-IFN-α-2b was discontinued for toxicity in 37% of patients. Conclusion: Adjuvant PEG-IFN-α-2b for stage III melanoma had a positive impact on RFS, which was marginally significant and slightly diminished versus the benefit seen at prior follow-up (median, 3.8 years). No significant increase in DMFS or OS was noted in the overall population. Patients with ulcerated melanoma and lower disease burden had the greatest benefit.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
