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

backgroundAdjuvant tamoxifen reduces breast cancer recurrence risk and mortality; however, initiation and treatment persistence are poor for younger patients. We hypothesized that a unique set of factors, including fertility concerns, would contribute to the poor tamoxifen use among premenopausal patients.

methodsFrom 2007 to 2012, 515 premenopausal patients younger than age 45 years, with stage 0 to III hormone receptor-positive breast cancer, for whom tamoxifen was recommended, were identified. Clinical and pathologic tumor characteristics, treatment regimens, and fertility concerns were recorded. Clinical factors associated with tamoxifen noninitiation and discontinuation were identified using univariate and multivariable analysis. After the recommendation for tamoxifen, patient reasons for tamoxifen noninitiation or discontinuation were also documented. All statistical tests were two-sided.

resultsBased on multivariable analysis, fertility concerns were statistically associated with both noninitiation (odds ratio = 5.04, 95% confidence interval (CI) = 2.29 to 11.07) and early discontinuation (hazard ratio = 1.78, 95% CI = 1.09 to 3.38) of tamoxifen. Other independent predictors of noninitiation included a diagnosis of ductal carcinoma in situ, declining radiation, and not receiving chemotherapy (stage I-III). Additionally, smoking and not receiving radiation therapy were statistically significant predictors of early withdrawal from therapy. Primary patient reasons for noninitiation and early discontinuation included concerns about side effects and fertility.

conclusionThis study provided insight into factors associated with tamoxifen use for reproductive-aged breast cancer survivors, with a new focus on fertility. Fertility concerns negatively impacted tamoxifen initiation and continuation among premenopausal patients. Interventions to optimize treatment initiation and persistence for young cancer patients should include access to fertility preservation options.
