Methods: Adult patients with treatment-naive AM who received ≥1 dose of ipilimumab 3 mg/kg between April 2011 and September 2012 were retrospectively identified at US Oncology sites. Clinical data were abstracted from patient medical records. Results: Median age of the 157 patient cohorts was 66 years (range 21 - 91). 68.2% were male, and 90.5% had a cutaneous primary site. At ipilimumab initiation, 80.9% of patients had an ECOG performance status of 0 or 1;54.1% were stage M1c;34.4% had brain metastases;24.8% had elevated lactate dehydrogenase, and 13.4% were positive for BRAF mutation. All 4 cycles of ipilimumab were completed by 55.8% of patients. At a median follow-up of 8.5 months (range 2.9 - 15.0), median overall survival was 11.5 months (95% CI: 8.9 - 16.6) and 1-year survival was 46.7% (95% CI: 38.1 - 54.9). During ipilimumab treatment, AEs were experienced by 63.7% of patients. The most frequent AEs were gastrointestinal (41.4%;diarrhea in 19.1%) and skin-related (28.0%;rash in 17.8%);17.8% of patients had an AE that led to ipilimumab discontinuation. Conclusions: These real-world results are consistent with those from clinical trials and provide evidence supporting the effectiveness and safety of first-line ipilimumab 3 mg/kg monotherapy in patients with AM treated in a community practice setting.展开更多
