Haploidentical hematopoietic SCT increases graft-versus-tumor effect against renal cell carcinoma.
Article in Bone marrow transplantation, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Allogeneic hematopoietic SCT (HSCT) has been shown to be an effective treatment option for advanced renal cell cancer (RCC). However, tumor resistance/relapse remains as the main post transplant issue. Therefore, enhancing graft-versus-tumor (GVT) activity without increasing GVHD is critical for improving the outcome of HSCT. We explored the GVT effect of haploidentical-SCT (haplo-SCT) against RCC in murine models. Lethally irradiated CB6F1 (H2K(b/d)) recipients were transplanted with T-cell-depleted BM cells from B6CBAF1 (H2K(b/k)) mice. Haplo-SCT combined with a low-dose haploidentical (HI) T-cell infusion (1 × 10(5)) successfully provided GVT activity without incurring GVHD. This effect elicited murine RCC growth control and consequently displayed a comparative survival advantage of haplo-SCT recipients when compared with MHC-matched (B6D2F1CB6F1) and parent-F1 (B6CB6F1) transplant recipients. Recipients of haplo-SCT had an increase in donor-derived splenic T-cell numbers, T-cell proliferation and IFN-γ-secreting donor-derived T-cells, a critical aspect for anti-tumor activity. The splenocytes from B6CBAF1 mice had a higher cytotoxicity against RENCA cells than the splenocytes from B6 and B6D2F1 donors after tumor challenge. These findings suggest that haplo-SCT might be an innovative immunotherapeutic platform for solid tumors, particularly for renal cell carcinoma.
