New trends in criteria indicative of neoadjuvant oncological therapy of lower and middle rectal cancers.

The indication for primary surgical resection or neoadjuvant therapy in lower and middle rectal cancers is often disputable. The aim of the study was to evaluate the occurrence of local recurrence of rectal cancer as for a period of at least 4 years after radical resection. The second aim was to evaluate and compare the results of preoperative magnetic resonance (MR) staging with definitive histology.

Squamous cell rectal cancer in a young woman.

Background: Rectal squamous cell carcinoma (RSCC) belongs to rare gastrointestinal malignancies. There are no consensus recommendations for the treatment of non-metastatic RSCC, which can cause problems when considering optimal therapy.

Purpose: The objective of this report is to point out that RSCC is a rare disease which needs to be distinguished from anal squamous cell cancer (ASCC) and the treatment of which differs from that of rectal adenocarcinoma.
