Hypothesis

What are the prognostic factors affecting survival in esophageal squamous cell carcinoma (ESCC) cases in Golestan Province, Iran?

Conclusion

The prognosis of esophageal squamous cell carcinoma in Golestan is very poor, with several factors influencing survival.

Supporting Evidence

  • Median survival for ESCC cases was found to be 7 months.
  • Older age was associated with poorer prognosis, but this association disappeared after adjusting for treatment.
  • Urban residents had better prognosis compared to rural residents.
  • Nass chewing was associated with poorer prognosis even after adjusting for other factors.

Takeaway

This study looked at people with a type of throat cancer in Iran and found that many things, like age and treatment, can affect how long they live after being diagnosed.

Methodology

The study followed up 426 ESCC cases from a population-based case-control study and analyzed data using Kaplan–Meier and Cox proportional hazard models.

Potential Biases

Potential cultural differences in treatment consent and access to medical facilities may introduce bias.

Limitations

Staging data were not available for many participants, and socioeconomic status indicators were only available for less than half of participants.

Participant Demographics

Participants were diagnosed with ESCC in Golestan Province, Iran, with a mix of urban and rural residents.
