Adjuvant intravesical treatment in patients with intermediate and high-risk non-muscle-invasive bladder cancer with BCG versus MMC applied with COMBAT or EMDA. Results of a prospective study.
Observational study in Journal of cancer research and clinical oncology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundBacillus Calmette-Guerin (BCG) maintenance therapy is the standard adjuvant treatment of high- and intermediate-risk non-muscle-invasive bladder cancer (NMIBC). However, the problems of shortages and the adverse effects, both local and systemic, that it causes lead to the search for alternatives with devices that improve the penetration of intravesical chemotherapeutics. MATERIALS AND
methodsProspective observational study was conducted from August 2018 to August 2022. Patients diagnosed with intermediate and high-risk NMIBC without CIS who received one of the following three treatments were included: BCG in induction protocol with six weekly instillations and maintenance with three weekly instillations at months 3, 6, and 12. MMC was applied by Physionizer
resultsOne hundred and eighty-three patients divided into a HIVEC group with sixty-one patients, EMDA group with fifty-nine patients, and BCG group with sixty-three patients. After a mean follow-up of 25 months (IQR 13-36), the 24-month recurrence-free rate was 82.1% for HIVEC, 80% for EMDA, and 84.6% for BCG (p > 0.05), and a progression-free rate at 24 months of 95.6% for HIVEC, 98.3% for EMDA, and 92.9% for BCG (p > 0.05). No statistically significant differences were found between the three groups with respect to the degree of reported adverse events.
conclusionAdjuvant treatment with BCG or MMC applied with COMBAT or EMDA does not present differences in the recurrence-free rate and progression at 24 months in our population of patients with intermediate- and high-risk NMBC without CIS.
