DNA polymerase theta (Polθ): a novel candidate for targeted cancer therapy.
Review in Cancer biology & therapy, 2026. 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
DNA double-strand breaks (DSBs) are the most severe DNA damage, and defective repair can lead to apoptosis or malignant transformation. DSBs are mainly repaired by nonhomologous end joining (NHEJ) and homologous recombination (HR), while microhomology-mediated end joining (MMEJ) serves as a backup pathway. Since DNA polymerase theta (Polθ) is essential for MMEJ, this pathway is also named Polθ-mediated end joining. Polθ is barely expressed in normal tissues but overexpressed in many cancers, making it a promising therapeutic target. In recent years, Polθ inhibitors and related therapeutic strategies have emerged rapidly, with clinical trials underway. This review summarizes the structure, function and expression of Polθ in tumorigenesis, highlights synthetic lethal strategies, drug development and clinical translation, and discusses current limitations and future directions for cancer research.
