The specimen should be submitted along with an associated pathology report. Multiple samples may be provided as available, but priority should be given to tissue with the highest tumor content and lowest necrotic area.
- •- Intention to receive a standard of care adjuvant chemotherapy (AdCTx) within 8 weeks post-surgery, and be scheduled for at least 3 months of treatment (including rest days) according to the treating physician or investigator.

- •- Prior systemic investigational therapy.
- •- Positive serology for hepatitis B (unless immune due to vaccination or resolved natural infection or unless passive immunization due to immunoglobulin therapy):
- •- Positive test for antibodies to hepatitis B core antigens (anti HBc) and
- •- Negative test for antibodies to hepatitis B surface antigens (anti HBs).
- •- Active hepatitis C virus (HCV) infection; participants who have completed curative antiviral treatment with HCV viral load below the limit of quantification by polymerase chain reaction (PCR) are allowed.
- •- Participant has a history of human immunodeficiency virus (HIV) antibody positivity, or tests positive for HIV at screening. - Residual tumor classification following surgery other than R0 (microscopic margin-negative resection).
- •- Participants with known past or current malignancy other than inclusion

- •- Cervical carcinoma of Stage 1B or less.

- •- Participant has not started standard of care AdCTx within 8 weeks post-surgery.
- •- Participant has received less than 3 months (including rest days) of AdCTx treatment.
- •- Inadequate tumor material (either quality or quantity) to support circulating tumor DNA (ctDNA) analysis.
