Two or three cycles of induction chemotherapy in locoregionally advanced nasopharyngeal carcinoma?
Article in BMC cancer, 2025. 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
purposeTo investigate the optimal cycles of induction chemotherapy (IC) in patients with locoregionally advanced nasopharyngeal carcinoma (LANPC).
methodsWe included LANPC patients treated with two or three IC cycles from January 2015 to December 2021. The chi-square test, Kaplan-Meier method, propensity score matching (PSM), and Multivariate Cox regression analyses were used for statistical analysis.
resultsA total of 491 patients were included in this study, of whom 166 (33.8%) received two cycles and 325 (66.2%) received three cycles of IC. Patients with stage IVA disease (P < 0.001), advanced T stage (P = 0.011), and advanced N stage (P < 0.001) were more likely to receive three cycles of IC. Cox proportional hazards regression analyses showed that the number of IC cycles was not associated with better survival outcomes. Patients who received three cycles of IC had comparable LRFS (HR 0.992, 95% CI 0.525-1.875, P = 0.981), DMFS (HR 0.805, 95% CI 0.511-1.092, P = 0.351), PFS (HR 0.917, 95% CI 0.633-1.328, P = 0.645) and OS (HR 0.880, 95% CI 0.552-1.402, P = 0.590) compared to those with two cycles of IC. Similar results were found after PSM. No significant differences were found in the incidence of Grade 3-4 acute toxicities between the two and three-cycle groups. However, three cycles of IC significantly increased the incidence of Grade 1-2 leukopenia (P = 0.001), neutropenia (P = 0.015), anemia (P = 0.017), and vomiting (P = 0.024) compared to two cycles of IC.
conclusionsThe number of IC cycles (two or three) did not seem to affect the survival outcome of LANPC patients in this retrospective analysis. However, three cycles of IC were associated with a higher incidence of mild to moderate acute toxicities. Prospective studies in well-defined patient groups with a more uniform treatment program differing only in the number of IC cycles are warranted.
