Optimization of tissue microarray technique for breast cancer patients: a short communication.
Article in Annals of medicine and surgery (2012), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Tissue microarray (TMA) is a novel technique for studying different types of cancer tissues in one block. TMA is not yet established in Syria, so we aimed in this project to apply and set the most optimal conditions of TMA creation of breast cancer tissues at the Pathology Department of our institute. Materials and Methods: Eighty-eight blocks of breast cancer tissues were selected, considering the inclusion criteria. The tissue specimens of breast cancer patients were manually placed in the block by punching a core from a paraffin block, which was then released into a recipient block using a small trocar. Three different conditions were tested on the constructed TMA block. Results: We determined the most effective parameters that proved high quality: incubating the newly constructed block at a temperature of 43°C for 24 h in the oven and then cutting it the next day after cooling it to room temperature; also, cutting with a 5 μm thickness created the preferable stained slides later. CD3 staining showed high expression of tumor-infiltrating lymphocytes among triple-negative breast cancer patients and high expression of CD3 in triple-negative cancer patients. Conclusion: The optimization of parameters presented in our study resulted in perfect TMA generation and successful immunohistochemistry staining for cancer research at our institution.
