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

purposeWe evaluated the tolerability and cardiac safety of docetaxel, cyclophosphamide, and trastuzumab (TCyH) for the treatment of early-stage human epidermal growth factor receptor 2 (HER2)-positive breast cancer and compared to the standard trastuzumab-based chemotherapy regimens doxorubicin with cyclophosphamide followed by paclitaxel and trastuzumab (AC-TH) and docetaxel, carboplatin, and trastuzumab (TCaH).

methodsWe retrospectively reviewed early-stage, resectable, HER2-positive breast cancer patients treated with trastuzumab-based chemotherapy at a single comprehensive cancer center between 2004 and 2011. Patient characteristics, comorbidities, relative dose intensity (RDI) of each regimen, tolerability, and cardiac toxicity were evaluated.

resultsOne hundred seventy-seven patients were included in the study (AC-TH, n=114; TCaH, n=39; TCyH, n=24). TCyH was solely administered in the adjuvant setting, whereas two-thirds of the AC-TH and TCaH groups were administered postoperatively. Patients treated with TCyH tended to have a more significant underlying cardiac history, higher Charlson comorbidity index, and were of an earlier stage. All patients treated with TCyH received granulocyte colony stimulating factor primary prophylaxis. No febrile neutropenia or grade ≥3 hematologic toxicity was observed in the TCyH group as compared to the AC-TH and TCaH groups. There were no significant differences in the rates of early termination, hospitalization, dose reduction, or RDI between the regimens. The symptomatic congestive heart failure rate between AC-TH, TCaH, and TCyH groups was not significantly different (4.4% vs. 2.6% vs. 8.3%, respectively, p=0.57). There was also no significant difference in the rate of early trastuzumab termination between patients treated with each regimen.

conclusionTCyH is well tolerated and should be investigated as an alternative adjuvant chemotherapy option for patients who are not candidates for standard trastuzumab-containing regimens. Larger clinical trials are necessary to support the wider use of TCyH as an adjuvant regimen.
