Intraoperative lokale Tumorzelldissemination in der Rektumkarzinomchirurgie

Abstract

Even in the era of TME surgery attention must to be paid to avoidance of LTCD. It is obligatory to document the occurrence of LTCD and it must be taken into consideration in routine quality assurance. In cases of LTCD postoperative chemoradiation is indicated for patients without neoadjuvant irradiation.

Individualized magnetic resonance imaging‐based neoadjuvant chemoradiation for middle and lower rectal carcinoma

“…Intra‐operative tumour cell dissemination, which may occur as a result of iatrogenic perforation of the bowel or cutting into the tumour, leads to an increase of local recurrences of up to 60% [72]. This is observed in specialist centres in around 4.5% of cases, but can increase, in some institutions, to 30% [70–74]. The German Working Group [69] specified less than 5% as a quality target for anterior resection and less than 10% as a quality target for abdomino‐perineal excision.…”
