Salvage chemotherapy after progression on immunotherapy in recurrent/metastatic squamous cell head and neck carcinoma.
Article in Frontiers in oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Objectives: Anti-PD-(L)1 agents changed the landscape of recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) treatment. Previous studies showed improved response rates to salvage chemotherapy (SCT) after progression to anti-PD-(L)1 agents. This study aims to evaluate the outcomes of SCT and to identify predictors of response and survival in patients with R/M HNSCC. Materials and methods: Retrospective cohort analysis of 63 R/M patients treated with SCT after antiPD-(L1)-based therapy between January 2015 and August 2022. The overall response rate (ORR) was evaluated. Progression-free survival (PFS) and overall survival (OS) were estimated with Kaplan-Meier method. Progression-free survival 2 was calculated from anti-PD-(L)1-therapy start until progression to SCT (PFS2-I). Logistic regression and Cox regression analyses were performed to identify predictors of outcome. Results: A total of 63 patients were included: 76% were men, and median age was 60 years. PD-L1 status was available in 68% (61% positive). Up to 71% received SCT as third line or beyond. ORR to SCT was 49% with higher rates in PD-L1 positive tumors, 71% vs. 18% (p=0.001), and cetuximab-containing regimens, 68% vs. 39% (p=0.026). PD-L1 status was the only predictor of ORR in the adjusted model (OR=8.6, 95% CI 1.7-43.0). OS and PFS were 9.3 months (95% CI, 6.5-12.3) and 4.1 months (95% CI, 3.0-5.8) respectively. PFS2-I was 8.6 months (95% CI, 6.6-10.5). In the multivariate analysis, PD-L1 was the only independent factor for OS (HR=0.3; 95% CI, 0.1-0.7), PFS (HR=0.2; 95% CI, 0.1-0.5; p<0.001), and PFS2-I (HR=0.2; 95% CI 0.1-0.5; p<0.001). Conclusion: PDL1 status appeared as a strong predictor of response of efficacy for SCT after anti-PD-(L)1 agents. Patients receiving cetuximab-containing regimens trended towards greater benefit. This highlights the importance of treatment sequencing and personalized treatment strategies.
