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

backgroundAlthough combination therapy consisting of a luteinizing hormone-releasing hormone (LH-RH) agonist and an Androgen receptor (AR) inhibitor has demonstrated promising clinical activity for recurrent and/or metastatic SGC (R/M SGC), few studies on LH-RH agonist monotherapy have been reported.

methodsWe conducted a retrospective analysis of patients with AR-positive, R/M SGC treated by monotherapy with LH-RH agonists in our institution from November 2004 to July 2023.

resultsNineteen patients were identified; the median age was 64 years (range 42-82), 10 had salivary duct carcinoma (52.6%), and 3 had adenocarcinoma, not otherwise specified (15.8%). LH-RH agonist monotherapy was delivered as first-line systemic therapy for R/M disease in 16 patients (84.2%). Nine patients (47.4%) achieved tumor size reduction in target lesions with a median tumor shrinkage of 11% (range 1-100%), resulting in an overall response rate and clinical benefit rate (rate of patients achieving a complete response, partial response, or stable disease lasting for at least 24 weeks) of 15.8% and 36.8%, respectively. The median duration of treatment with LH-RH agonist monotherapy was 5.1 months (range 0.3-63.4), accounting for 35.2% of the entire treatment period. Median progression-free survival and overall survival was 3.2 months (95% confidence interval (95% CI), 1.6-6.0) and 21.6 months (95% CI 9.9-34.4), respectively. No severe adverse events leading to treatment interruption or discontinuation were seen.

conclusionLH-RH agonist monotherapy demonstrated a well-balanced profile between efficacy and safety and could be an alternative therapeutic option, especially for subjects not tolerable to combination therapy. (242 words).
