HER2 overexpression as a prognostic factor in metastatic breast cancer patients treated with high-dose chemotherapy and autologous stem cell support.
Article in Bone marrow transplantation, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
We retrospectively evaluated the predictive and prognostic role of HER2 expression in 44 metastatic breast cancer (MBC) patients treated with high-dose consolidation chemotherapy (HDCT) and autologous stem cell support after induction chemotherapy (IC) with six courses of epirubicin+paclitaxel (22 patients) or gemcitabine+epirubicin+paclitaxel (22 patients). HER2 expression was evaluated by an immunohistochemical method (Herceptest, Dako). A total of 13 patients (29.5%) showed a HER2 overexpression (score 3+). After IC, nine patients were in complete response (CR), 30 in partial response (PR), and five in stable disease (SD); after HDCT, 20 (45.5%) obtained a CR, and 23 were in PR, for a conversion rate of 48.5%. Conversion rate for HER2-positive patients was 87.5 vs 37% for HER2-negative patients (P=0.018). The median progression-free (PFS) and overall survivals (OS) were 17.6 (95% CI 13.2-22.0) and 44 (95% CI 25.9-62.3) months, respectively. Patients with HER2 overexpression experienced a significantly (P=0.0042) shorter median PFS (15.3 months, 95% CI 11.1-19.5) compared to HER2-negative patients (21.3 months, 95% CI 14.3-28.4). The median OS was 27.6 months (95% CI 4.5-50.7) in HER2-positive patients and 50.3 months (95% CI 38.7-62.0) in HER2-negative patients (P=0.345). These results indicate that HER2 overexpression predicts a worse outcome for patients with MBC treated with HDCT, despite the high CR rate obtained in this subset of patients.
