Multimodal treatment according to the NPC-GPOH trials in adult patients with nasopharyngeal cancer-Analysis based on a single-center experience.
Article in Cancer reports (Hoboken, N.J.), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND AND
aimThe German NPC-GPOH trials introduced treatment including neoadjuvant chemotherapy, radiochemotherapy (RCT) and antiviral treatment in patients aged 25 years or younger with nasopharyngeal cancer (NPC). We conducted a retrospective study on outcomes of patients at the age of ≥26 years treated accordingly at our institution.
methodsConsecutive patients who received primary RCT for NPC were included. The Kaplan-Meier method was used to calculate survival probabilities, and the Cox regression analysis was used to test for an influence of the variables on outcomes. Acute and late toxicity were evaluated via CTCAE criteria and LENT/SOMA criteria, respectively.
resultsIn total, 30 patients were included. Diagnosis was made from 09/1994 to 11/2016. The median 5 year overall survival (OS), disease-free survival (DFS), cancer-specific survival (CSS) and locoregional recurrence-free survival (LRC) were 75%, 56%, 83%, and 85%, respectively. We found a negative impact on outcomes (p < .05) in case of older age (OS), history of smoking (OS), and T4 stage/ UICC stage IV (DFS). WHO histologic type significantly influenced outcomes, with best outcomes for type III and worst outcomes for type I. The rates of acute and late toxicities were acceptable.
conclusionWe found excellent outcomes and good feasibility of the NPC-GPOH trials regimen in adult patients. Additionally, we identified patients with outcomes which need to be improved (smokers, histologic type I tumors) and with particularly excellent outcomes (histologic type III tumors). This stimulates further studies on treatment intensification or de-escalation aiming at reduced side effects with optimal tumor control in NPC.
