Colorectal cancer

The cancer where screening works best and where immunotherapy can make some tumours disappear entirely, yet most metastatic disease still depends on chemotherapy.

Colorectal cancer is the third most common cancer and second leading cause of cancer death worldwide (about 1.9 million cases and 900,000 deaths a year). It is the disease where screening works best: removing adenomas at colonoscopy prevents cancer, and stool and blood tests catch it early. Most cases arise through the adenoma-carcinoma sequence driven by APC loss, KRAS mutation, and TP53 loss (chromosomal instability); about 15% arise through mismatch-repair deficiency (dMMR/MSI-high), either sporadically via MLH1 methylation or through Lynch syndrome. Incidence is rising sharply in adults under 50 for reasons that remain unexplained.

Treatment splits along biology. Localised disease is cured by surgery, with adjuvant FOLFOX or CAPOX for stage III (3 months suffices for low-risk disease) and, since ATOMIC (2025), atezolizumab added for dMMR stage III. Rectal cancer uses total neoadjuvant therapy with chemoradiation and increasingly organ preservation; dMMR rectal cancer can be treated with six months of dostarlimab and no surgery at all (AZUR-1, FDA priority review). Metastatic disease is stratified by RAS, BRAF, HER2, MSI, and sidedness: left-sided RAS/BRAF wild-type tumours get chemotherapy with an EGFR antibody (PARADIGM); others get bevacizumab; BRAF V600E disease gets encorafenib + cetuximab + chemotherapy first line (BREAKWATER, OS doubled to 30 months); KRAS G12C disease gets sotorasib or adagrasib with an EGFR antibody; HER2-amplified disease gets tucatinib + trastuzumab or T-DXd; dMMR disease gets pembrolizumab or nivolumab + ipilimumab first line, with 5-year survival above 50%. Later lines: trifluridine/tipiracil + bevacizumab (SUNLIGHT), fruquintinib (FRESCO-2), regorafenib. Liver-limited metastases are resected or ablated with curative intent in a meaningful minority.

Unsolved: the 95% of metastatic tumours that are microsatellite-stable remain immunotherapy-resistant; KRAS G12D (the commonest mutation) is undrugged; early-onset CRC has no explanation and no screening; ctDNA can identify who will relapse after surgery but no escalation strategy has yet been shown to change that (ALTAIR negative); and anti-EGFR resistance via RAS/EGFR ectodomain clones, MET amplification, and HER2 amplification is universal in metastatic disease.

State of the art today

  • ctDNA-guided adjuvant therapy.
  • Immunotherapy cures in dMMR without surgery.
  • First-line targeted therapy for BRAF V600E.
  • Adjuvant atezolizumab for dMMR stage III colon cancer halves recurrence (ATOMIC, 2025): the first adjuvant IO success in CRC.
  • ctDNA-guided de-escalation is proven (DYNAMIC); blood-based screening is FDA-approved (Shield, 2024) and Medicare-covered.
  • KRAS G12C and HER2 have approved targeted combinations; RAS(ON) inhibitors are entering phase 3 for the remaining KRAS alleles.

Averages across everyone diagnosed, often years ago. Your stage, subtype, age, fitness and the treatment you receive matter more than the average, and the numbers are improving quickly.

  • dMMR disease: immunotherapy first line gives median OS over 6 years (KEYNOTE-177); neoadjuvant IO achieves 68% pCR and 100% 3-year DFS in colon (NICHE-2) and complete organ preservation in rectal cancer (dostarlimab, AZUR-1).
  • BRAF V600E first-line targeted triplet doubled survival to 30 months (BREAKWATER); full approval in 2026.
  • Sidedness plus RAS/BRAF status selects anti-EGFR therapy, yielding median OS near 38 months first line (PARADIGM).

Open problems

  • MSS metastatic disease is immunotherapy-resistant.
  • Early-onset CRC causes unknown.
  • KRAS G12D (most common) undrugged.
  • Microsatellite-stable metastatic disease (95%) remains immunotherapy-resistant; liver metastases actively suppress systemic immunity.
  • KRAS G12D and G12V, the most common drivers, have no approved inhibitor; RAS(ON) inhibitors are the first credible attempt.
  • Early-onset colorectal cancer is rising ~2% per year with no established cause and no screening before 45.
  • ctDNA identifies who will relapse but no escalation strategy has changed outcomes (ALTAIR negative).
  • Anti-EGFR resistance is universal; rechallenge and ctDNA-guided sequencing are unproven in phase 3.
  • Rectal cancer organ preservation lacks randomised comparison against surgery in pMMR disease.
  • Peritoneal metastases respond poorly to systemic therapy; HIPEC with oxaliplatin failed (PRODIGE 7).
  • Disparities: screening uptake and outcomes differ sharply by race, income, and geography.

BREAKWATER: encorafenib plus cetuximab with chemotherapy as first treatment for BRAF V600E-mutated colorectal cancer

Patients with newly diagnosed metastatic colorectal cancer whose tumour carries a BRAF V600E mutation, which is about 8-12% of cases, should now be offered encorafenib and cetuximab together with FOLFOX from the start rather than after chemotherapy fails; median survival has roughly doubled to about two and a half years. BRAF testing at diagnosis is therefore essential, alongside RAS and mismatch repair testing. The regimen is more toxic than chemotherapy alone.

CHALLENGE: a structured exercise programme after chemotherapy improves survival in colon cancer

For colon cancer survivors, a prescribed, supported exercise programme is now an evidence-based treatment with a survival benefit comparable to many drugs. Health systems will need to fund exercise consultants as they fund chemotherapy. The trial does not tell us whether unsupervised advice achieves the same.

NICHE-2: a month of nivolumab and ipilimumab before surgery clears mismatch-repair-deficient colon cancer in most patients

For colon cancer that is mismatch-repair deficient (about 10-15% of colon cancers, more in older patients), a single short course of immunotherapy before surgery is now a reasonable standard and is far more effective than chemotherapy, which barely works in this subtype. It requires testing every colon cancer for mismatch repair at diagnosis, before surgery. Whether some patients can safely skip surgery, as in dMMR rectal cancer, is the next question.

NICHE-2: a single dose of ipilimumab and two of nivolumab before surgery clears dMMR colon cancer in most patients

NICHE-2 shows that a month of immunotherapy before surgery can effectively cure locally advanced dMMR colon cancer, where chemotherapy after surgery has limited benefit. It is changing guidelines towards neoadjuvant checkpoint blockade for this group and raises the question of whether surgery can be omitted altogether, as in dMMR rectal cancer. Whether the same applies to MMR-proficient tumours is being tested but is not established.

CodeBreaK 300: sotorasib plus panitumumab in chemotherapy-refractory KRAS G12C colorectal cancer

Patients with metastatic colorectal cancer carrying a KRAS G12C mutation (about 3-4% of cases) who have exhausted standard chemotherapy now have a targeted option that works far better than trifluridine-tipiracil or regorafenib. The higher sotorasib dose is clearly superior, and the EGFR antibody is essential because KRAS inhibition alone barely works in bowel cancer. Responses are still modest and short-lived compared with EGFR or ALK inhibitors in lung cancer.

GALAXY: tumour DNA in blood four weeks after bowel cancer surgery predicts relapse tenfold

The blood test stratifies risk far better than stage or pathology. It supports treating ctDNA-positive patients and suggests ctDNA-negative patients gain little from chemotherapy, but because treatment was not randomised the de-escalation claim needs the randomised trials that are now under way.

Cercek 2022: six months of dostarlimab alone made rectal cancer disappear in every patient with mismatch-repair deficiency

Cercek's dostarlimab study is the clearest demonstration that immunotherapy can replace surgery in a solid tumour: patients with dMMR rectal cancer can keep their rectum and avoid the permanent effects of pelvic radiotherapy and surgery. Non-operative management after PD-1 blockade is now in guidelines for this group, and MMR testing before treatment of rectal cancer is essential. The approach applies only to the 5-10% of rectal cancers that are dMMR.

Dostarlimab alone cures mismatch-repair-deficient rectal cancer without surgery or radiotherapy

Patients with rectal cancer whose tumour is mismatch-repair deficient (about 5-10% of rectal cancers) can now be offered immunotherapy alone with the realistic expectation of avoiding surgery, radiotherapy and a permanent stoma. This requires mismatch repair testing on the diagnostic biopsy, close endoscopic and MRI surveillance, and treatment in an experienced centre. It does not apply to the 90% of rectal cancers that are mismatch-repair proficient.

DYNAMIC: a blood test safely halved chemotherapy use after surgery for stage II colon cancer

For stage II colon cancer, where most patients are cured by surgery alone, a blood test can identify the minority who benefit from chemotherapy and spare everyone else its side effects. It does not yet prove that treating ctDNA-positive patients improves survival compared with not treating them.

NordICC: inviting people to a screening colonoscopy reduced bowel cancer, but less than expected

A colonoscopy probably does reduce bowel cancer risk for the person who has it, but a programme that offers colonoscopy achieves much less if most people decline. Programmes based on stool tests with high uptake may deliver as much population benefit at lower cost and risk.

Alcohol caused an estimated 741,000 cancers worldwide in 2020

There is no safe level of alcohol for cancer risk, and the risk is highest for cancers of the mouth, throat, oesophagus, liver, bowel and breast. Public awareness is low; most people do not know alcohol causes breast cancer. Warning labels and minimum pricing are the policy levers being debated.

CAPP2: two years of aspirin cuts bowel cancer in Lynch syndrome by more than a third over 10 years

People with Lynch syndrome should be offered daily aspirin, which roughly halves bowel cancer risk with a delayed and durable effect. Whether a lower dose (as tested in CAPP3) is as effective, and whether the finding extends to the general population, are separate questions.

First trial of a vaccine against the shared neoantigens of mismatch-repair-deficient cancers

Because Lynch syndrome tumours make the same abnormal proteins in almost every patient, a single vaccine could in principle be given to carriers before cancer develops. This small trial showed the concept is safe and immunogenic; whether it prevents cancer requires the randomised trials now being planned.

KEYNOTE-177: pembrolizumab instead of chemotherapy as first treatment for mismatch-repair-deficient metastatic colorectal cancer

Every colorectal cancer should be tested for mismatch repair deficiency, because patients whose metastatic tumour is dMMR should receive pembrolizumab rather than chemotherapy as first treatment, gaining a much better chance of durable remission with fewer side effects. About a third of dMMR tumours do not respond initially, so early scans are essential and chemotherapy remains available. The trial does not apply to the 95% of colorectal cancers that are mismatch-repair proficient.

Le 2017: mismatch-repair deficiency predicts response to PD-1 blockade across twelve tumour types, leading to the first tissue-agnostic drug approval

This paper established a new regulatory paradigm: a drug approved for a molecular feature regardless of organ. It made MSI/MMR testing standard across advanced cancers and remains the clearest example of a biomarker that works across histologies. It also anchored the idea that mutation load, via neoantigens, is what makes tumours visible to T cells.

IARC verdict: excess body fat causes 13 cancers

Maintaining a healthy weight is now established cancer prevention for over a dozen cancer types. For clinicians and policymakers, obesity belongs alongside tobacco and alcohol in prevention strategy. Whether intentional weight loss in adulthood reverses risk is still being studied, including in trials of GLP-1 drugs.

Le 2015: PD-1 blockade works in tumours with mismatch-repair deficiency, whatever the organ

This small trial explained why colorectal cancer had seemed immune-resistant (most is MMR-proficient) and established the principle that a genomic feature, not the tissue of origin, can predict immunotherapy response. It led directly to the 2017 tissue-agnostic approval of pembrolizumab and to routine MMR/MSI testing of many cancers. Every patient with advanced dMMR cancer should now be considered for checkpoint blockade.

Ostrem and Shokat: the hidden pocket that made KRAS G12C druggable

The most frequently mutated oncogene in cancer stopped being undruggable, and patients with KRAS G12C lung and bowel cancers now have targeted pills. The approach, exploiting a mutation-created chemical handle and an inactive-state pocket, has become a template for other hard targets.
