1 · What the graph read from 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.

2 · The registry

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

contextAmong patients with locally advanced head and neck squamous cell cancers (LAHNSCC), the prognosis after nonresponse or progression despite induction chemotherapy (IC) is dismal, and further treatment is often palliative in intent. Given that nonresponse to chemotherapy could indicate subsequent radioresistance, we intended to assess the outcomes with two different fractionation schemes.

aimsTo compare the outcomes of two fractionation schemes- 'standard' (consisting 3GyX5 daily fractions for 2 consecutive weeks) versus 'hybrid' (6GyX3 fractions on alternate days during the 1(st) week, followed by 2GyX5 daily fractions in the 2(nd) week). SETTINGS AND

designProspective randomized controlled two-arm unblinded trial. MATERIALS AND

methodsPatients with locally advanced oropharyngeal, laryngeal, and hypopharyngeal cancers treated with a minimum of two cycles of taxane, platinum, and fluorouracil-based IC were eligible if residual disease volume amounted <30 cm(3). Kaplan-Meier survival curves were compared by the log-rank test. Response rates were compared using the unpaired t-test. Quality of life (QOL) was measured via patient reported questionnaires.

resultsOf the initially enrolled 51 patients, 45 patients (24 from standard arm, and 21 from the hybrid arm) were eligible for analysis. Despite being underpowered to attain statistical significance, there still seemed to be a trend towards improvement in progression-free (Hazard ratio (HR) for progression: 0.5966; 95% CI 0.3216-1.1066) and overall survival (HR for death: 0.6062; 95% CI 0.2676-1.3734) with the hybrid arm when compared to the standard arm. Benefits were also observed with regards to response rates and QOL. Rate of complications were similar in both arms.

conclusionsIn comparison to the routinely used palliative fractionation scheme of 30 Gray (Gy) in 10 fractions (Fr), the use of hybrid fractionation which integrates hypofractionation in the 1(st) week, followed by conventional fractionation in the 2(nd) week, could possibly offer better response rates, QOL increments, and potential survival benefits among LAHNSCC patients even after failing to respond to IC.
