T Staging: Rectal cancer
T1 invades submucosa
T2 invades muscularis propria
T3 invades subserosa or perirectal tissues
T4 invades peritoneum, organs or structures(15% of cases)

T4 Strategy: Staging
EUA, cystoscopy
MR pelvis
CT abdo, thorax
? PET scan
![Page 14: T Staging: Rectal cancer](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814903550346895db636b6/html5/thumbnails/14.jpg)
T4 Strategy: Adjuvant therapy
RTH
Chemo/RTH
Intra op RTH
HIPEC: Hyperthermic Intra Peritoneal CT
![Page 15: T Staging: Rectal cancer](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814903550346895db636b6/html5/thumbnails/15.jpg)
Pre-operative RTH plays a major role
Only a minority will be cured with RTH alone
Pre-operative CRTH has increased risks
Phase II studies oxaliplatin, irinotecan and
capecitabine
What do we do with complete regression?
Adjuvant Rx for fixed tumours
![Page 16: T Staging: Rectal cancer](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814903550346895db636b6/html5/thumbnails/16.jpg)
Current optimum CRT schedule
Radiotherapy with 3 or 4 field plan
45 Gy in 25 # over 5 weeks
Capecitabine 825mg/m2 bd for 5 weeks
![Page 17: T Staging: Rectal cancer](https://reader036.fdocuments.in/reader036/viewer/2022062423/56814903550346895db636b6/html5/thumbnails/17.jpg)

What of it! She would have died anyway without the operation.
There you are gentleman,you’ve seen the operation that everyone said was impossible, performed with complete success.
But Doctor, the patient’s dead!

RTH for fixed rectal tumours
• 45 - 65% have potentially curable resections after radiotherapy
• 50% develop local recurrence
• Only a minority will be cured with RTH alone
