Brief Summary
Early rectal cancer can be removed by minimally-invasive surgery, and the standard pathological assessment of the removed tumour gives valuable information about how advanced the tumour is. This gives an indication of how likely the cancer is to recur, so doctors and patient can decide on the most appropriate further treatment and follow-up. However there is still much uncertainty in these predictions about recurrence. This study will assess two further pathology tests, ploidy and stroma ratio in the tumour, by correlating the results with outcome. This will determine whether these two tests provide additional value in predicting outcome. If so, clinicians would be better able to advise patients with early rectal cancer about their prognosis and further management.

Outcome Measures
Primary Outcomes (2)
Correlation Between Ploidy Status With Local Recurrence of Cancer
Results of ploidy status will be correlated with patient follow-up information for between 6 months and 9 years following surgery, to look for any correlation with local recurrence of the rectal cancer
a minimum of 6 months after surgery
Correlation Between Tumour: Stroma Ratio With Local Recurrence of Cancer
Results of tumour:stromal ratio (TSR) will be correlated with patient follow-up information for between 6 months and 9 years following surgery, to look for any correlation with local recurrence of the rectal cancer. A 50% cut-off is used to define high TSR.
a minimum of 6 months after surgery
Secondary Outcomes (2)
Correlation Between Ploidy Status and Overall Survival After TEM Surgery to Remove Rectal Cancer
a minimum of 6 months after surgery
Correlation Between Tumour:Stroma Ratio and Overall Survival After TEM Surgery to Remove Rectal Cancer
a minimum of 6 months after surgery
Interventions
Ploidy and tumour:stromal ratio measurements will be made on specimens of early rectal cancer removed by transanal endoscopic microsurgery (TEM)
Eligibility Criteria
Participants diagnosed with rectal cancer that is operable and patients who have already had rectal cancer removed by transanal endoscopic microsurgery (TEM) in Oxford since 2007.
You may qualify if:
- Participant is willing and able to give informed consent (in English) for participation in the study, or gave informed consent for donation of tissue for research at the time of surgery
- Male or Female, aged 18 years or above
- Diagnosed with operable rectal cancer
- Due to undergo, or has already undergone, TEM surgery to remove rectal cancer
- A useable tissue sample has already been, or will be, taken as part of routine surgery
You may not qualify if:
- Age less than 18
- Adults who are not able to give consent or who are deemed vulnerable
- Participants who do not have a useable tissue sample will be excluded
