Contemporary approaches to colon tumour management
This review outlines contemporary clinical approaches to managing colon tumours, emphasising early detection through screening, coordinated diagnostics, and a multidisciplinary treatment pathway. It summarises the roles of endoscopy and biopsy, surgical and systemic options including chemotherapy and immunotherapy, the use of biomarkers for personalised care, and the importance of survivorship and rehabilitation.
Effective management of colon tumours depends on timely detection, precise diagnostics and coordinated care across specialties. Screening programmes, imaging and pathology establish stage and biology, which guide choices between endoscopic removal, surgery, systemic therapies and radiotherapy. Multidisciplinary tumour boards integrate surgical, medical and radiation oncology input with pathology and molecular testing to personalise treatment plans and balance oncologic control with long‑term function and quality of life.

Screening and diagnostics
Population screening reduces mortality by identifying precancerous polyps and early-stage tumours when interventions are most curative. Typical pathways combine stool-based tests and colonoscopy, supported by cross-sectional imaging when required. Diagnostics include laboratory markers and risk assessment based on age, family history and prior polyps. Timely diagnostic work-up enables accurate staging and referral to appropriate local services, while risk‑adapted surveillance intervals aim to detect recurrence or new lesions early.
Endoscopy and biopsy
Endoscopic assessment remains central: high-definition colonoscopy visualises mucosal lesions and permits targeted biopsy or endoscopic resection for suitable polyps and superficial tumours. Biopsy specimens provide histology and material for molecular assays used in treatment selection. Advanced endoscopic techniques can reduce the need for major surgery in selected cases, but coordinated reporting between endoscopists and pathologists is essential to ensure the diagnostic information supports subsequent therapeutic decisions.
Surgery and staging
Surgical resection is the primary curative modality for localized disease. Choice of procedure—segmental colectomy, low anterior resection or more limited endoscopic excision—depends on tumour location and stage. Minimally invasive approaches, including laparoscopic and robotic techniques, aim to preserve oncological principles while reducing recovery time. Accurate pathological staging of resected specimens, including lymph node assessment, informs the need for adjuvant systemic therapy and refines prognosis.
Chemotherapy and radiotherapy
Systemic chemotherapy is widely used for stage III and selected stage II cancers as adjuvant therapy, and for advanced or metastatic disease to control tumour burden and prolong survival. Regimen selection considers stage, performance status and molecular features. Radiotherapy has a particular role in rectal tumours for downstaging and local control, usually integrated with chemotherapy when indicated. Treatment sequencing is tailored to clinical goals and patient preferences, balancing efficacy and toxicity.
Immunotherapy and biomarkers
Molecular biomarkers increasingly guide personalised therapy. Tests for microsatellite instability, RAS and BRAF mutations and other actionable alterations help predict response to targeted agents and immunotherapy. Immune checkpoint inhibitors may offer substantial benefit for biomarker-defined subgroups, and targeted therapies address specific driver mutations. Integrating pathology and molecular diagnostics into the care pathway enables more precise therapy selection and can support eligibility for clinicaltrials exploring novel agents or combinations.
Survivorship, rehabilitation and clinicaltrials
Post‑treatment care focuses on surveillance for recurrence, management of late effects and functional rehabilitation. Rehabilitation services address bowel function, nutritional support, physical conditioning and psychosocial needs to improve return to daily activities. Survivorship plans include scheduled follow-up imaging and endoscopy where appropriate. Participation in clinicaltrials may be an option for patients with recurrent or advanced disease and should be considered within a multidisciplinary framework to expand therapeutic choices.
Conclusion Contemporary care for colon tumours combines effective screening, robust diagnostics and a multidisciplinary approach that personalises surgery, systemic therapy and radiotherapy according to staging and molecular features. Close integration of endoscopy, pathology and biomarker testing supports tailored treatment decisions, while survivorship care and rehabilitation aim to restore function and support long‑term well‑being. Ongoing clinical research continues to refine strategies and expand options for patients.
