These epithelial invaginations, referred to as RokitanskyAschoff sinuses, form diverticula, which extend into the subserosa and often contain inspissated bile, stones, or mucus.
1 * T1 = tumour invades submucosa; T2 = tumour invades muscularis propria; T3 = tumour invades through the muscularis propria into the subserosa nonperitonealised pericolic tissues; T4 = tumour directly invades other organs or structures and/or perforates visceral peritoneum; N0 = no regional lymph note netastasis; N1 = metastasis to one to three regional lymph nodes; N2 = metastasis to four or more regional lymph nodes; M0 = no distant metastasis; M1 = distant metastasis.
In addition, after APR, patients whose pathologic findings indicate malignant invasion of rectal subserosa will need adjuvant chemotherapy and radiation to reduce the risk of cancer recurrence.
Krystyna Kiel said the guidelines now recommend FOLFOX as an option for adjuvant therapy for a variety of patients: those with primary tumors invading through the muscularis propria into the subserosa or into the non-peritoneal pericolic or perirectal tissues; those with any level of primary tumor and metastases to one or more regional lymph nodes; and those with any level of primary tumor, any number of regional lymph node metastases, and distant metastasis.

More advanced lesions, including any involving lymph node metastases, and any without lymph node metastases that invade the muscularis propria, the subserosa, or non-peritonealized pericolic or perirectal tissues, or those that directly invade other organs or structures require mitomycin/5-EU therapy plus radiotherapy at 55-59 Gy the guide-lines state.
