Hypothesis

The study investigates the prognostic value of RBM3 protein expression in malignant melanoma.

Conclusion

High nuclear RBM3 expression in primary melanoma is an independent marker of prolonged overall survival.

Supporting Evidence

  • RBM3 expression was assessed in 215 out of 226 primary tumors.
  • Strong RBM3 expression was significantly associated with favorable clinicopathological parameters.
  • High RBM3 expression correlated with prolonged recurrence-free survival and overall survival.

Takeaway

RBM3 is a protein that helps doctors understand how serious melanoma is; more of it in tumors means patients tend to live longer.

Methodology

The study used immunohistochemistry to analyze RBM3 expression in tissue microarrays from melanoma patients.

Potential Biases

Potential bias related to the TMA technique and the selection of cases for analysis.

Limitations

The study may have selection bias due to the population-based cohort design and the use of tissue microarrays.

Participant Demographics

The cohort included 264 individuals, with a mean age of 67.29 years, comprising 51.1% females and 48.9% males.

Statistical Information
