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

The mammalian target of rapamycin (mTOR) inhibitor, in combination with other chemotherapeutic drugs, has been used for treatment of breast cancer that develops resistance to endocrine therapy. However, the efficacy and safety need further evaluation. Here, we report a meta-analysis of randomized controlled trials (RCT) in breast cancer patients undergoing chemotherapy using steroid (exemestane) or nonsteroid (letrozole) aromatase inhibitors with or without mTOR inhibitors (everolimus). The overall response rate (ORR), progression-free survival (PFS), clinical benefi;t rate with 95% confidence interval (CI), and the major toxicities/adverse effects were analyzed. Data were extracted from twelve studies that meet the selection criteria. Among these, six studies that enrolled 3693 women received treatment of everolimus plus exemestane, or placebo with exemestane. The results showed that everolimus plus exemestane significantly increased the ORR relative risk (relative risk = 9.18, 95% CI = 5.21-16.15), PFS hazard ratio (hazard ratio = 0.44, 95% CI = 0.41-0.48), and clinical benefi;t rate (relative risk = 1.92, 95% CI 1.69-2.17) compared to placebo control, while the risks of stomatitis, rash, hyperglycemia, diarrhea, fatigue, anorexia and pneumonitis also increased. Three studies that enrolled 715 women who received everolimus as neoadjuvant therapy were analyzed. Compared to chemotherapy with placebo, chemotherapy plus everolimus did not increase the ORR relative risk (relative risk = 0.90, 95% CI = 0.77-1.05). Meanwhile, two other studies that enrolled 2104 women examined the efficacy of temsirolimus (or placebo control) plus letrozole. The results indicated that emsirolimus plus letrozole did not increase the ORR relative risk and clinical benefi;t rate (p > 0.05). Together, these data suggest that the combined mTOR inhibitor (everolimus) plus endocrine therapy (exemestane) is superior to endocrine therapy alone. As a neoadjuvant, everolimus did not increase the ORR, while temsirolimus plus letrozole treatment has limited effect on the ORR and the CBR of breast cancer patients.
