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.

2512 Background: Since 2015, ipilimumab (Ipi) is an approved treatment for stage III melanoma based on a significantly (P=0.0013) prolonged recurrence-free survival (RFS) (Eggermont et al, Lancet Oncology, 2015). At a median follow-up of 5.3 years, RFS (HR=0.76) and distant metastasis-free survival (DMFS) (HR=0.76), assessed by an IRC, and overall survival (OS) (HR=0.72) were prolonged in the Ipi group as compared to the placebo (Pbo) group (Eggermont et al, NEJM, 2016), despite a 53.3% (Ipi) vs 4.6% (Pbo) treatment discontinuation rate due to adverse events. Methods: In this randomized double-blind trial, eligible patients (pts) included those ≥18 yrs of age who underwent complete resection of stage III cutaneous melanoma (excluding lymph node metastasis ≤1 mm or in-transit metastasis). 951 pts were randomized (stratified by stage and region) 1:1 to Ipi 10 mg/kg (n=475) or placebo (Pbo, n=476) q3w for 4 doses, then every 3 mos for up to 3 yrs until completion, disease recurrence, or unacceptable toxicity. Here, we report the comparison between the Ipi and Pbo groups regarding the long-term efficacy outcomes using the local investigator assessments. Results: Overall, 20%/44%/36% of pts had AJCC-7 stage IIIA/IIIB/IIIC, 42% ulcerated primary, and 58% macroscopic lymph node involvement. Median follow-up was 6.9 yrs. The RFS, DMFS and OS benefit observed in the Ipi group was long-lasting (almost 10% difference at 7 years) and consistent across subgroups: no significant predictive factors could be detected. Conclusions: In this phase III trial, Ipi, administered at 10 mg/kg, as adjuvant therapy provided, at a 6.9 yr median follow-up, a sustained improvement in the RFS, DMFS, and OS long-term results in patients with high-risk stage III melanoma. Clinical trial information: NCT00636168. [Table: see text]

Radiotherapy (RT) and interferon-alfa-2b (IFN α-2b) have individually been used for adjuvant therapy stage III melanoma with high-risk pathologic features. We hypothesized that concurrent adjuvant RT and IFN α-2b may decrease the risk of regional recurrence following surgery with acceptable toxicity. A prospective multicenter phase I/II study was conducted to evaluate hypofractionated RT with concurrent IFN. Induction IFN α-2b, 20 MU/m2/d, was administered IV ×5 consecutive days every week for 4 weeks. Next, RT 30 Gy in 5 fractions was given with concurrent IFN α-2b, 10 MU/m2 SQ 3 times per week on days alternating with RT. Subsequent maintenance therapy consisted of adjuvant IFN α-2b, 10 MU/m2 SQ 3 times per week to a total of 1 year. To fully evaluate patterns of failure, long-term follow-up was conducted for up to 10 years. A total of 29 consenting patients were enrolled between August 1997 and March 2000. The maximum (worst) grade of acute nonhematologic toxicity during concurrent RT/IFN α-2b (and up to 2 weeks post RT) was grade 3 skin toxicity noted in 2 patients (9%). Late effects were limited. Probability of regional control was 78% (95% CI: 55%–90%) at 12 months. The median follow-up (range) was 80 (51–106) months among ten survivors (43%). The median overall survival was 34.5 months while the median failure-free survival was 19.9 months. Postoperative concurrent hypofractionated RT with IFN α-2b for advanced stage III melanoma appears to be associated with acceptable toxicity and may provide reasonable in-field control in patients at high risk of regional failure.
