Immunohistochemical and mutational status of telomerase reverse transcriptase in conjunctival squamous cell carcinoma.
Article in Indian journal of ophthalmology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
purposeMutations in human telomerase reverse transcriptase (TERT) are associated with increased telomerase activity in cutaneous melanomas. Conjunctival squamous cell carcinoma, also referred to as ocular surface squamous cell carcinoma, is cancer on the surface of the eye. Recent studies have identified UV signat`ure mutations in TERT promoters in ocular melanoma and ocular surface squamous neoplasia. However, its immunohistochemical status has not been reported in ocular surface squamous cell carcinoma. This study aimed to explore the immunohistochemical and mutational status of TERT in ocular surface SCC.
methodsThe immunohistochemical expression of TERT and mutational status of TERT promoter was evaluated in 19 ocular surface squamous cell carcinoma cases. Conjunctival melanoma tissue was used as a positive control.
resultsThe cytoplasmic overexpression of TERT was detected in 11/19 (57%), and TERT promoter mutations were identified in 6/19 (31%) of ocular surface squamous cell carcinoma. Out of these, 66% had a C228T mutation, and 33% had a C250T mutation. The TERT expression was found to be associated with a high (≥T3) AJCC category (P = 0.023), and TERT immunoexpression was significantly correlated with reduced disease-free survival (P = 0.024, log-rank analysis) in ocular surface squamous cell carcinoma patients.
conclusionThe present study demonstrates that TERT promoter mutations with UV signatures are frequent in ocular surface squamous cell carcinoma. The increased expression of TERT could be of biological significance in aggressive ocular surface squamous cell carcinoma.
