Neoadjuvant chemoimmunotherapy with afatinib for locally advanced head and neck squamous cell carcinoma (neoCHANCE-2): an open-label, single-arm, phase 2 study.
Trial report in Journal for immunotherapy of cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05516589 (Neoadjuvant Chemotherapy, Tislelizumab With Afatinib for the Treatment of Resectable Head and Neck Squamous Cell Carcinoma), which is not on this map.

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.

Abstract
backgroundWhile immune checkpoint inhibitor-based neoadjuvant therapy shows promise in locally advanced head and neck squamous cell carcinoma (LA-HNSCC), the optimal regimen has yet to be established. We report, for the first time, a neoadjuvant treatment that combines chemotherapy with dual blockade of the programmed cell death protein 1 and epidermal growth factor receptor pathways in LA-HNSCC.
methodsIn this single-arm phase 2 trial (NCT05516589) conducted at a single academic center, patients with LA-HNSCC were enrolled and received two cycles of tislelizumab and TP chemotherapy (nab-paclitaxel and cisplatin), administered on day 1 of each 3-week cycle, along with afatinib during the interval between chemoimmunotherapy cycles, followed by surgical resection. The primary endpoint was the complete pathologic response (pCR) rate. Secondary endpoints included the major pathologic response (MPR) rate, objective response rate (ORR), event-free survival, overall survival (OS), and safety.
resultsA total of 40 patients were enrolled and received neoadjuvant treatment, 32 of whom proceeded to surgical resection; among these patients, the pCR rate was 40.6% (95% CI 23.7% to 59.4%). The ORR was 82.5% (95% CI 67.2% to 92.7%). The 1-year OS rate was 97.3% (95% CI 92.2% to 100%). The most common treatment-related adverse event (TRAE) of grade 3-4 was lymphopenia (5/40, 12.5%). No grade 5 TRAEs leading to death occurred, and no treatment-related surgical delays were observed. In the prespecified exploratory biomarker analysis, increased cytotoxic T lymphocytes and B cells in the tumor immune microenvironment may be associated with pCR/MPR. Neoadjuvant treatment induced a significant increase in the proportion of peripheral CD8+T cells, along with a reduction in B cells.
conclusionsWe report, for the first time, the promising efficacy and acceptable safety profile of neoadjuvant chemoimmunotherapy combined with afatinib in patients with LA-HNSCC. Neoadjuvant treatment potentially induced an immune-enhanced tumor microenvironment. Further evaluation in large-scale clinical trials with longer follow-up periods is needed.
