@ APR or low anterior resection can be done
@ in cases of well diff ca 2cm margin n in anaplastic ca 5cm margin clearance necessary

@ rectal cancers r more radiosensitive  and colonic r more chemo sensitive
@ neutron beam radiation 4000-5000 cGy units
@ pre op radiotherapy when tumor extended thro wall
@ post op 2 reduce recurrence
@ Papillon's intra cavity radiation indicated 4 small localised n exophytic ca as curative therapy
