NOM can be considered if the rectal tumor disappears with neoadjuvant treatment, resulting in a complete clinical response.\n\nObjective: The aim of the study is to establish a unified NOM protocol for national use and determine whether the outcomes of Finnish and Estonian treatment practices align with international experiences.\n\nDesign: The study is a prospective, non-randomized, single-arm, international multicenter trial examining the oncological and quality-of-life consequences of NOM.\n\nPrimary Endpoint: The primary endpoint is disease-free survival 2 years after the initiation of NOM.\n\nSecondary Endpoints: These include overall survival, disease-specific survival, survival free from total mesorectal excision (TME) surgery, survival free from circulating tumor DNA (ctDNA) detection after complete clinical response, recurrence-free survival, incidence of local recurrence and metastases, salvage TME success rate, quality of life at 1 year post-NOM, and treatment-related morbidity up to 5 years.\n\nInclusion Criteria: Patients must have histopathologically confirmed primary rectal adenocarcinoma before neoadjuvant treatment, achieve clinical complete response (cCR) after neoadjuvant therapy, and express willingness to undergo rectum-preserving treatment after considering the risk of recurrence.\n\nExclusion Criteria: Patients with evidence of metastasis at diagnosis, aged under 18, those not receiving neoadjuvant treatment, or those unable to provide informed consent are excluded.\n\nDiagnosis and Treatment: Pretreatment of patients follows standard practice. Upon meeting inclusion criteria with confirmed cCR, patients undergo protocolized monitoring with clinical examination, laboratory tests, and imaging.\n\nRandomization: No randomization is performed.\n\nFollow-up: Patients are monitored every 3 months for the first 2 years, then every 6 months for 3 years. Monitoring replaces surgical intervention unless cancer recurs. Follow-up is part of standard care, with costs covered by the healthcare system.\n\nSafety: Incidence of local recurrence and success of resection post-recurrence are monitored closely. If over 30% local recurrence occurs post-cCR, it may necessitate study termination at the center.\n\nData Collection: Clinical data are entered into electronic case report forms (eCRFs) based on primary healthcare documentation and stored pseudonymized on the primary research center's server. Molecular and pseudonymized clinical data are collected securely for analysis.\n\nSample Size Calculation and Statistical Analysis: A sample of 200 patients is estimated to provide sufficient data for the primary and key secondary endpoints and to meet other study objectives accurately.\n\nData Handling: Data handling adheres to privacy legislation, with information stored pseudonymously.",[58],{"label":59,"type":60,"description":61,"interventionNames":62},"Nonoperative management","EXPERIMENTAL","The patients presenting with complete clinical response undergo
