Short Course Brachytherapy in Locally Advanced Cervical Cancer; Safety and Response Rate.
Trial report in Asian Pacific journal of cancer prevention : APJCP, 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
objectiveOverall treatment time (OTT) is an important index for local control in patients with locally advanced cervical cancer treated with definitive chemoradiation (External Beam Radiation Therapy (EBRT), Brachytherapy (BT) and concomittant chemotherapy). This study aimed to evaluate the efficiency and safety of reducing OTT by shortening the brachytherapy duration to one week in the intervention group copared to three weeks in the control group.
methodThe study was a non-randomized open-label phase II clinical trial, carried out on 49 cervical cancer patients (26 in intervention grouop and 23 in control group) who received EBRT concomitant with Cisplatin, followed by brachytherap in order to deliver 60 Gy equivalent total doses in 2-Gy fractions (EQD2) to Intermediate Risk-Clinical Tumor Volume (IR-CTV) and 85-90 Gy EQD2 to High Risk-Clinical Tumor Volume (HR-CTV). In the intervention group, all brachytherapy sessions were performed in 1 week, while for the control group, it was administrated in 3 consecutive weeks. The participants were followed (Minimum follow up time was 6 month and median follow up time was 10 month) to assess response and toxicity of the treatment.
resultsOverall, more than 95% of study participants had a complete response and more than 4.0% reported partial response, and no treatment failure was observed. The complete response in intervention and control groups was 96.1% and 95.6%, respectively (P value > 0.05). There was no difference in acute toxicity between the two groups.
conclusionconsidering that short course brachytherapy was non inferior to conventional course from point of Response Rate and Side Effects during follow up time; so this strategy can be considered as an option for reducing the OTT which can at least cause decreasing the costs. Studies with larger sample size and phase 3 are recommended.
