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
introductionStandard of care (SoC) for resectable locally advanced head and neck squamous cell carcinoma (LA-HNSCC) is surgery with adjuvant radiotherapy (RT) or chemoradiotherapy (for tumors at high risk of recurrence). As long-term prognosis is suboptimal with SoC, this study aimed to summarize findings from recent studies comparing alternative treatments to SoC.
methodsA broad systematic literature review (search date: December 1, 2025) searched Embase, MEDLINE, and CENTRAL to identify randomized controlled trials evaluating surgery with RT and/or systemic treatments in the neoadjuvant and/or adjuvant setting in LA-HNSCC. Trials published since 2004 were included in this report if they compared interventions to SoC in terms of event-free survival (EFS) and overall survival (OS) or reported pathological response following neoadjuvant therapy.
resultsFifty-six trials were included in the broader review, of which 25 were included in this report. Trials reporting EFS counted at least recurrence/progression and death as events, except one that did not provide a definition. Improvement in EFS (regardless of definition) was reported with the addition of perioperative pembrolizumab or addition of perioperative camrelizumab with neoadjuvant nab-paclitaxel + carboplatin to surgery + RT ± cisplatin, addition of adjuvant cetuximab or adjuvant cisplatin to surgery + RT, and addition of adjuvant nivolumab to surgery + RT + cisplatin. EFS with other interventions was comparable to SoC. OS was generally comparable between interventions and SoC. Across treatment arms with at least one neoadjuvant chemotherapy agent, pathological complete response rates ranged from 10.5% to 42.6% while it ranged from 0 to 12.9% in treatment arms without any neoadjuvant chemotherapy agent. Some trials reported an association between achieving pathological response and improved survival outcomes in exploratory analyses.
conclusionImmunotherapy shows promise as an addition to the SoC in LA-HNSCC. OS results are generally comparable and may still be immature in some trials. Evidence on pathological response suggests potential prognostic value for long-term survival outcomes.
