Abstract

The Glasgow Prognostic Score (GPS), combination of C-reactive protein and albumin, has proven its prognostic value in metastatic colorectal cancer (mCRC) patients receiving conventional cytotoxic therapy. More recently, anti-EGFR therapies have been validated in mCRC and roll forward the patients' overall survival (OS). We aimed to evaluate the prognostic accuracy of the GPS in patients receiving anti-EGFR therapy in addition to conventional chemotherapy. From January 2007 to February 2012, consecutive mCRC patients who received 5-fluorouracil-based chemotherapy plus cetuximab were included in the present analysis. Patients were eligible for the study if they met the following criteria: advanced pathologically proven MCRC, age >18 years, adequate renal function (creatinine clearance >40 ml/min), C-reactive protein and albumin and performance status evaluation before treatment initiation. A total of 49 patients received cetuximab plus 5-fluorouracil-based chemotherapy (colon, n = 34; rectum, n = 15) and were treated with a median follow-up of 35 months (16.5-74.7). Median age was 48 years old. In addition to cetuximab, patients received oxaliplatin- (n = 34, 60%) or irinotecan (n = 15, 30%)-based chemotherapy. At time of diagnosis, 55, 29 and 16% of patients had a GPS of 0 (n = 27), 1 (n = 14) and 2 (n = 8), respectively. Fifty-five, 29 and 14 % of patients add one, two or ≥3 metastatic sites, respectively. Considering two groups (GPS = 0 and GPS ≥1), median progression-free survivals were significantly different (p = 0.0084). Median OS in the GPS 0, 1 and 2 groups were 38.2, 14 and 12.1 months, respectively (p = 0.0093). The results of the present study confirm that the GPS is still a simple and effective prognostic factor in the era of cetuximab therapy in mCRC patients.
