Key inclusion & exclusion criteria

Inclusion Criteria:

1. Subjects with histologically confirmed stage II and III rectal adenocarcinoma or
subjects with histologically confirmed stage II and III anal SCC

2. Subjects greater than 18 years of age.

3. Subjects who will undergo prescribed neoadjuvant chemotherapy and/or radiotherapy and
have surgical resection prior to further treatment or pathologic confirmation of
treatment response using endoscopy or ultrasound.

4. Subjects with:

- twenty (20) unstained sections on charged slides available from tumor block
(FFPE) used for the diagnosis of rectal/anal carcinoma or adjacent to this block
(pre-neoadjuvant biopsy sample); and

- four (4) unstained slides available from post-chemoradiation surgery to allow for
blinded pathology review and assessment of pathCR, partial CR, or exCTRT. Slides
from surgical resection are not necessary in cases with documented post-surgical
determination of response by ultrasound or endoscopy.

5. Subjects willing to complete study follow up for outcomes.

6. Subjects from who informed consent can be obtained.

Exclusion Criteria:

1. Subjects with carcinoma in situ or Stage I rectal/anal carcinoma.

2. Subjects with Stage IV rectal/anal carcinoma.

3. Subjects with diagnosis of other malignant tumors with the exception of non-melanoma
skin cancers cured by resection only.

4. Subjects that have received prior chest or upper abdomen radiotherapy and/or system
chemotherapy within the past 5 years

5. Subjects who are unwilling to complete study follow up

6. Employees and family members of Investigator

Primary Outcome(s)
Gene expression profiling will be undertaken to determine if RNA is a superior biomarker to protein [Time Frame: at time of enrollment (visit 1) tissue will be sent for testing]
