Trial Title: NCI UNC Project ESCC

Study Design Characteristics:
- Allocation: None
- Intervention Model: None
- Observational Model: CASE_CONTROL
- Primary Purpose: None
- Time Perspective: OTHER
- Masking: None
- Phase: None
- Number of Arms: None

Eligibility Criteria:
* INCLUSION CRITERIA:~* All suspected ESCC cases will be eligible for enrollment.~* All KCH and St Gabriel s patients greater than or eqaul to 18 years of age who are residents of the Central Region of Malawi and are diagnosed with histology-confirmed ESCC will be invited to participate as cases in the study.~EXCLUSION CRITERIA:~* Patients \<18 years old~* Those living outside the Central Region, those who are medically unable to complete the study procedures (including questionnaire, biosample collection or endoscopy), and those who are unable to understand the study procedures or give informed consent.~While we do expect to see younger people with ESCC in Malawi (as we have seen in Kenya), cases under the age of 18 are rare: the field team would expect to see one or two a year. This estimate is in line with the cancer registry data from Malawi. Therefore, we will not enroll subjects younger than 18 years old.
