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

backgroundThe equivalency of survival between mastectomy and breast conservation therapy (BCT) has long been established, resulting in two decades of predominant BCT. Recently, surgeons have recognized a trend toward increasing mastectomy. Institutional trends of mastectomy and BCT were reviewed, confirming this perception in the surgical treatment of breast cancer. This report evaluates the factors that influence patient decisions to choose surgical therapies.

methodsPatients who underwent mastectomy or BCT for invasive and in situ breast cancer were identified upon retrospective review of a prospectively accrued breast cancer database between 1994 and 2007. Univariate and multivariate logistic regression analysis were used to estimate the odds ratio (OR) of the association between mastectomy and patients' clinicopathologic characteristics.

resultsOf the 5,865 patients, 3,736 underwent BCT and 2,129 underwent mastectomy. The overall surgical volume decreased during the study period. Mastectomy rates during the periods of 1994-1998, 1999-2003, and 2004-2007 were 33%, 33%, and 44%, respectively (P < 0.01). Immediate reconstruction rates decreased during the same time periods from 16%, 5%, and 7%, respectively (P < 0.01). On logistic regression analysis, gender, age < 40 years, increase tumor size, and lymphovascular invasion were significant independent predictors of mastectomy. The mastectomy rate increased during the period 1999-2003 (OR 1.2) and during 2004-2007(OR 1.8).

conclusionsThe perception of an increasing choice toward mastectomy has been confirmed at this institution. Possible reasons are younger population with higher lifetime risk, higher stage disease, and more biologically aggressive or diffuse tumors. Patient preference, fear of genetic or recurrence risk, and "intangible" factors seem to shift decisions toward mastectomy.
