Real-world adjuvant TAC or FEC-D for HER2-negative node-positive breast cancer in women less than 50 years of age.
Article in Current oncology (Toronto, Ont.), 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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 compared the efficacy, toxicity, and use of granulocyte colony-stimulating factor (g-csf) with tac (docetaxel-doxorubicin-cyclophosphamide) and fec-d (5-fluorouracil-epirubicin-cyclophosphamide followed by docetaxel) in women less than 50 years of age.
methodsThe study included all women more than 18 years but less than 50 years of age with her2-negative, node-positive, stage ii or iii breast cancer diagnosed in Alberta between 2008 and 2012 who received tac (n = 198) or fec-d (n = 274).
resultsThe patient groups were well-balanced, except that radiotherapy use was higher in the tac group (91.9% vs. 79.9%, p < 0.001). At a median follow-up of 49.6 months, disease-free survival was 91.4% for tac and 92.0% for fec-d (p = 0.76). Overall survival (os) was 96% with tac and 95.3% with fec-d (p = 0.86).The incidences of grades 3 and 4 toxicities were similar in the two groups (all p > 0.05). Overall, febrile neutropenia (fn) was reported in 11.6% of tac patients and 15.7% of fec-d patients (p = 0.26). However, use of g-csf was higher in the tac group than in the fec-d group (96.4% vs. 71.5%, p < 0.001). Hospitalization for fn was required in 10.5% of tac patients and 13.0% of fec-d patients (p = 0.41). In g-csf-supported and -unsupported patients receiving tac, fn occurred at rates of 11.1% and 33.3% respectively (p = 0.08); in patients receiving the fec portion of fec-d, those proportions were 2.9% and 8.1% respectively (p = 0.24); and in patients receiving docetaxel after fec, the proportions were 4.1% and 17.6% respectively (p < 0.001).
conclusionsIn women less than 50 years of age receiving adjuvant tac or fec-d, we observed no differences in efficacy or other nonhematologic toxicities. Based on the timing and rates of fn, use of prophylactic g-csf should be routine for the docetaxel-containing portion of treatment; however, prophylactic g-csf could potentially be avoided during the fec portion of fec-d treatment.
