Association of rs2294008 (PSCA) Gene polymorphism in Urothelial Bladder Cancer of South Indian Population.
Article in Asian Pacific journal of cancer prevention : APJCP, 2025. 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
backgroundUrothelial Bladder cancer (UBC) is a significant health problem worldwide. Prostate stem cell antigen (PSCA) gene has been reported earlier in Genome Wide Association Study (GWAS) for the risk of UBC. It is highly expressed in urothelial bladder tumours and considered to be involved in the cell proliferation inhibition and/or cell-death induction activity. The study aims to investigate PSCA gene as a possible marker for the diagnosis and prognosis of urothelial bladder cancer. PATIENTS AND
methodsWe genotyped PSCA rs2294008C/T gene by Real Time Taqman® probes to evaluate the risk of UBC in histologically confirmed bladder tumour patients 107 and healthy controls 105 (age and gender matched) in a hospital-based setting from South Indian population. Statistical analysis was carried out using (SPSS ver 22.0 Armonk NY, USA).
resultsThe heterozygous CT genotype showed increased significance risk to UBC with PSCA rs2294008 C/T having 2.77 folds risk (p<0.0001). The variant allele T was also significantly associated with UBC risk (p<0.0001; OR=3.349) for PSCA rs2294008C/T. A significant UBC risk was noted when risk was evaluated with tumor-grade-stage level for PSCA rs2294008C/T with heterozygous CT genotype for high grade tumours (p<0.001; OR=1.984). The smoking factor was significantly modulated with the risk of UBC in patients with heterozygous CT genotype (p<0.0001) for PSCA rs2294008C/T gene polymorphism. Urothelial Bladder cancer patients receiving BCG treatment showed no significant association with genotype of PSCA.
conclusionsThe present study has unveiled a complex intervention of PSCA rs2294008C/T conferring a higher risk of UBC risk among smokers in South Indian population, providing evidence that it may contribute to bladder carcinogenesis regardless of ethnicity. These findings suggest that the PSCA rs2294008C/T polymorphism of PSCA gene could be served as a biomarker for genetic susceptibility to bladder cancer in Indian populations.
