Real-World Outcomes of First-Line Cetuximab and Platinum-Based Chemotherapy in Recurrent and/or Metastatic Head and Neck Squamous Cell Carcinoma: A Multicenter Observational Study and Literature Review.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe EXTREME regimen (cetuximab with cisplatin/carboplatin and 5-fluorouracil) has long been a standard first-line treatment for recurrent and/or metastatic head and neck squamous cell carcinoma (R/M HNSCC), particularly in patients ineligible for immunotherapy. However, real-world evidence remains limited, especially in regions with delayed access to novel therapies.
methodsWe conducted a retrospective, multicenter study of 217 patients with R/M HNSCC treated with cetuximab-based chemotherapy at six Croatian oncology centers between 2016 and 2022, prior to reimbursement of pembrolizumab. The primary endpoint was overall survival (OS); secondary endpoints included progression-free survival (PFS), response rates, and safety.
resultsThe majority (91%) received the EXTREME regimen. Median OS was 14 months (95% CI, 12-17), and median PFS was 6.2 months (95% CI, 6.0-7.2). Objective response rate was 21%, and disease control rate was 63%. Cetuximab-induced rash correlated with longer PFS. Grade ≥ 3 toxicity occurred in 18.9% of patients. No treatment-related deaths were observed.
conclusionIn routine clinical practice, cetuximab combined with platinum-based chemotherapy remains an effective and well-tolerated first-line treatment for R/M HNSCC, particularly in patients who are ineligible for immunotherapy or with PD-L1-negative tumors. These findings support its continued use in appropriately selected patients.
