Long-term outcomes of induction chemotherapy followed by chemoradiotherapy vs chemoradiotherapy alone as treatment of unresectable head and neck cancer: follow-up of the Spanish Head and Neck Cancer Group (TTCC) 2503 Trial.
Observational study in Clinical & translational oncology : official publication of the Federation of Spanish Oncology Societies and of the National Cancer Institute of Mexico, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00261703 (Randomized Phase III Trial Comparing Induction Chemotherapy With Cisplatin/5-fluorouracil), which is not on this map. Cited by 12 papers, 3 of them syntheses that pooled it.
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.

Abstract
backgroundOur previous phase-3 study (TTCC 2503) failed to show overall survival advantage of 2 induction chemotherapy (IC) regimens followed by standard concurrent chemoradiotherapy (CRT) over CRT alone in patients with unresectable locally advanced head and neck squamous-cell carcinoma (LAHNSCC). This study described the long-term survival of those patients. MATERIALS AND
methodsLong-term follow-up study of patients with untreated LAHNSCC assigned to IC (three cycles), with either docetaxel, cisplatin and 5-fluorouracil (TPF arm) or cisplatin and 5-fluorouracil (PF arm), followed by CRT, or CRT alone, included in the previous TTCC 2503 trial.
resultsIn the intention-to-treat population (n = 439), the median OS times were 25.4 (95% CI, 16.8-34.4), 26.2 (95% CI, 18.2-36.6) and 25.4 months (95% CI, 17.4-36.0) in the TPF-CRT, PF-CRT and CRT arms, respectively (log-rank p = 0.51). In the per-protocol population (n = 355), patients with larynx-hypopharynx primary tumors treated with IC (TPF or PF) followed by CRT had a longer median PFS than those who received CRT alone. Moreover, patients with ECOG 0 treated with IC (TPF or PF) followed by CRT had a better TTF than those with CRT alone. There were no statistically significant differences in terms of OS, PFS or TTF, according to the tumor load or affected nodes.
conclusionAfter a long follow-up, the TTCC 2503 trial failed to show the benefit of IC-CRT in unresectable LAHNSCC regarding the primary end point. However, fit patients with ECOG 0 and primary larynx-hypopharyngeal tumors may benefit from the use of IC if administered by an experienced team. ClinicalTrials.gov identifier NCT00261703.
