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

introductionTotal mesorectal excision (TME) is highly effective for early-stage rectal cancer, but is associated with considerable morbidity, which can substantially impair the quality of life (QoL) of patients. For very early tumours (low-risk cT1), local excision (LE) offers the possibility of organ preservation (OP) with reduced morbidity; however, its application is limited to a selected group. For early tumours where upfront LE is not feasible, primary OP with (chemo)radiotherapy as an alternative to TME surgery has been evaluated in the STARTREC phase II/III studies, which reported promising 1-year OP rates.

objectiveThe STARTREC-3 trial aims to increase the 2-year OP rate from 60% to 80% in early rectal cancer (cT1-3abN0) and from 30% to 60% in early-intermediate rectal cancer (cT1-3abN1, ≤3 mesorectal nodes measuring ≤8 mm) by intensifying neoadjuvant treatment in different study arms.

methodsSTARTREC-3 is embedded in the STARTREC master trial protocol, which uses an adaptive platform study design allowing early termination of inferior treatment arms and the addition of novel arms. The multicentre STARTREC-3 trial investigates three parallel, non-comparative treatment strategies for patients with early and early-intermediate rectal adenocarcinoma who prefer OP over primary TME surgery. All arms start with 5×5 Gy radiotherapy, followed by: an endoluminal boost via contact X-ray brachytherapy (arm 1), an external beam radiotherapy (EBRT) boost by MR-guided EBRT (arm 2) or three cycles of capecitabine oxaliplatin systemic treatment chemotherapy (arm 3). Treatment allocation is predefined and centre-dependent. Response evaluations (MRI and endoscopy) are planned at 14-16 weeks and 26 weeks after onset of radiotherapy. The primary endpoint is the proportion of patients with successful OP at 24 months from onset of therapy. Secondary endpoints include toxicity, QoL, functional and oncological outcomes. Data will be analysed separately for early (cN0) and early-intermediate (cN1) disease. The total planned sample size is 210 patients across the three arms. Interim analyses will be performed for each study arm to determine early failures and discontinue ineffective arms. ETHICS AND DISSEMINATION: The trial was approved by the medical ethics committee NedMec of the Netherlands and is registered in the EU Clinical Trials Information System (CTIS). The results will be published in an international peer-reviewed journal. TRIAL REGISTRATION NUMBER: CTIS EU 2024-514620-17-00.
