CDK4/6 Inhibitor Palbociclib Amplifies the Radiosensitivity to Nasopharyngeal Carcinoma Cells via Mediating Apoptosis and Suppressing DNA Damage Repair.
Article in OncoTargets and therapy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
backgroundRadiotherapy is the primary approach for nasopharyngeal carcinoma (NPC). Although high survival rates can be obtained with radiation for early stage lesions, distant metastasis and local recurrence frequently occur. In this study, we pioneeringly investigated the antitumor activity and underlying mechanism of cyclin-dependent kinase 4/6 inhibitor (palbociclib) combined with radiation on NPC cells.
methodsEvaluation of radiation enhancement with palbociclib was based on results from CCK8 and clonogenicity assays for cell proliferation, flow cytometry for apoptosis, ROS level and cell cycle and immunocytochemistry for DNA double-strand break repair.
resultsPalbociclib inhibited cellular growth of RB-proficient CNE-1 and CNE-2 via reducing RB phosphorylation and arresting cell cycle. Combination regimens of palbociclib plus radiation were significantly superior to palbociclib or radiation only through inhibiting cellular growth and inducing apoptosis. Moreover, the antitumor activity of both concurrent palbociclib plus radiation and radiation followed by palbociclib consistently preceded that of palbociclib followed by radiation. Meanwhile, the two preferable combination regimens possessed higher proportion of G2/M phase cells, evidently inhibited DNA double-strand break repair and eventually triggered tumor cell apoptosis.
conclusionOur study demonstrated that palbociclib could provoke a strong antitumor activity as a potential adjuvant to radiation therapy for NPC harboring RB expression.
