Induction of leukemia-specific antibodies by immunotherapy with leukemia-cell-derived heat shock protein 70.
Article in Cancer science, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Cancer immunotherapy using heat shock protein (HSP) derived from autologous tumor requires cluster of differentiation (CD)4(+) as well as CD8(+) T-cells for the prolongation of patient survival, suggesting that a humoral immune response through CD4(+) T-cells is important in addition to cellular immunity. However, the role of humoral responses in HSP-based autologous tumor immunotherapy remains unclear. In the present study, we investigated whether leukemia-specific antibodies and antibody-mediated cytotoxicity against autologous leukemia cells have a crucial role in a mouse A20 leukemia model by immunizing A20-derived HSP70. Immunization with A20-derived HSP70 induced the production of anti-A20-antibodies and the antibodies recognized HSP70-binding peptides derived from A20. One of those was a major histocompatibility complex (MHC) class-I binding peptide, which has been clarified as the target peptide of CD8+ cytotoxic T-cells (CTL) against A20. The anti-A20-antibodies produced by immunization with A20-derived HSP70 induced complement-dependent cytotoxicity (CDC) against A20 in vitro. In addition, immunization with A20-derived HSP70 increased intracellular interleukin-4 (IL4)-production of CD4(+) T-cells, confirming the activation of type-2 helper T-cells. Taken together, immunization with leukemia-cell-derived HSP70 induces antibodies against leukemia-cell-specific peptides and might play a crucial role in the eradication of leukemia cells by CDC in mice. These findings will enable future establishment of a novel therapeutic strategy using antileukemia antibodies in HSP-based autologous tumor immunotherapy.
