Who this trial is looking for
This trial is looking for adults who have been treated for certain types of cancer and are planning regular follow-up for cancer monitoring. Participants will provide blood samples to help researchers determine how well a new test can detect cancer recurrence.
Are You a Good Fit for This Trial?
You may be able to join if
I am over 18 years old.
I have had initial treatment to cure my cancer.
I am planning to have regular check-ups for cancer recurrence.
I agree to participate in the study.
I am willing to provide blood samples for up to 3 years.
I have at least one blood sample collected after my treatment.
I have a confirmed diagnosis of a qualifying cancer.
You may not be able to join if
I have had an organ or tissue transplant.
My cancer has a neuroendocrine type.
I have been diagnosed with another cancer in the last 3 years, except for certain non-aggressive cancers.
I have known distant metastasis, unless it's limited/resectable melanoma or renal cell carcinoma.

Think this trial could be right for you?
Answer three quick questions written from this study's own rules to see if you may qualify. No account needed to find out.
The purpose of ORACLE is to demonstrate the ability of a novel ctDNA assay developed by Guardant Health to detect recurrence in individuals treated for early-stage solid tumors. It is necessary that ctDNA test results are linked to clinical outcomes in order to demonstrate clinical validity for recurrence detection and explore its value in a healthcare environment subject to cost containment.

Primary Study Cohorts
* Cohort 1: Cohort 1: Muscle invasive carcinoma of the bladder, ureter, or renal pelvis (stage II-III),

Cohort 3A: High-risk2 HER2+ breast cancer (any ER, PR status allowed) OR Cohort 3B: High-risk2 triple negative breast cancer (TNBC) OR Cohort 3C: High-risk3 HR-positive/HER2-negative invasive breast carcinoma,
* Cohort 4: Stage IIB-III cutaneous melanoma or limited (resectable) stage IV melanoma treated with curative intent,
* Cohort 5: Esophageal or gastroesophageal junction carcinoma (stage II-III),

* Cohort 9: High-risk epithelial ovarian or Fallopian tube carcinoma (defined as FIGO stage IC-III, stage IA-IB that has high grade, carcinosarcoma, or clear cell histology),
* Cohort 10: Endometrial carcinoma (2023 FIGO Stage II-III or 2023 FIGO Stage IC or any Stage I with p53 abnormal molecular subtype),
* Cohort 11: High-risk renal cell carcinoma (Defined as high grade (grade 3-4) stage II, stage III or limited stage IV (meaning metastatic sites are considered treatable with curative intent)
* Cohort 12: Colorectal adenocarcinoma Cohort 12A: Pathologically confirmed adenocarcinoma of the rectum (located up to 15 cm from the anal verge) that is undergoing or underwent a preoperative chemotherapy-or immunotherapy- containing regimen OR Cohort 12B: Colon adenocarcinoma (stage II-III)
Exclusion Criteria:
