Résumé

For (locally advanced) rectal cancer, a multimodal therapy concept comprising neoadjuvant radiotherapy/chemoradiotherapy, radical surgical resection with partial/complete mesorectal excision and subsequent adjuvant chemotherapy represents the current international standard of care. Further developments in neoadjuvant therapy concepts, such as the principle of total neoadjuvant therapy, lead to an increasing number of patients who show a complete clinical response in restaging after neoadjuvant therapy without clinically detectable residual tumor. In view of the risk associated with radical surgical resection in terms of perioperative morbidity and a potentially non-continence-preserving procedure, the question of the oncological justifiability of an organ-preserving procedure in the case of a complete clinical response under neoadjuvant therapy is increasingly being raised. The therapeutic principle of watch and wait, defined by refraining from immediate radical surgical resection and inclusion in a close-meshed, structured follow-up program, currently appears to be oncologically justifiable based on the current study situation; however, for the initial evaluation of the extent of the clinical response and for the structuring of the close-meshed follow-up program, further optimization and standardization based on broadly designed studies appear necessary in order to be able to provide this concept to a clearly defined patient collective as an oncologically equivalent therapy principle also outside specialized centers. Für das (lokal fortgeschrittene) Rektumkarzinom stellt heute ein multimodales Therapiekonzept aus neoadjuvanter Radiatio/Radiochemotherapie, radikaler chirurgischer Resektion mit partieller/kompletter mesorektaler Exzision und anschließender adjuvanter Chemotherapie den internationalen „standard of care“ dar. Weiterentwicklungen in den neoadjuvanten Therapiekonzepten wie das Prinzip der totalen neoadjuvanten Therapie führen zu einer zunehmenden Anzahl an Patienten, die im Restaging nach erfolgter Neoadjuvanz ein vollständiges klinisches Ansprechen ohne klinisch nachweisbaren Residualtumor aufweisen. In Anbetracht des mit einer radikalen chirurgischen Resektion verbundenen Risikos hinsichtlich perioperativer Morbidität und ein potenziell nicht kontinenzerhaltendes Vorgehen stellt sich zunehmend die Frage nach der onkologischen Vertretbarkeit eines organerhaltenden Vorgehens bei vollständigem klinischem Ansprechen unter neodjuvanter Therapie. Das Therapieprinzip des „watch and wait“, definiert durch das Unterlassen einer unmittelbaren radikalen chirurgischen Resektion und Einschluss in ein engmaschiges, strukturiertes Nachsorgeprogramm, erscheint gegenwärtig, anhand der aktuellen Studienlage, als onkologisch vertretbar. Allerdings erscheint für die initiale Bewertung des Umfangs des klinischen Ansprechens und für die Strukturierung des engmaschigen Nachsorgeprogramms eine weitere Optimierung und Standardisierung auf Basis breit angelegter Studien notwendig, um dieses Konzept auch außerhalb spezialisierter Zentren einem klar definierten Patientenkollektiv als onkologisch gleichwertiges Therapieprinzip anbieten zu können.
