Bevacizumab was first approved in 2004 for metastatic colorectal cancer and has since become one of the most broadly indicated oncology biologics. It functions as an anti-angiogenic agent by neutralising VEGF-A, thereby starving tumours of their blood supply. The drug is used across diverse solid tumour types, always administered intravenously and almost always in combination with cytotoxic chemotherapy or, in the case of HCC, with the immune checkpoint inhibitor atezolizumab. Notably, bevacizumab is not indicated for adjuvant treatment of colon cancer, as clinical trials showed no benefit in this setting.

Clinical Pearl: No Dose Reductions

There are no recommended dose reductions for bevacizumab. Management of adverse reactions involves either withholding or permanently discontinuing the drug (see Dose Modifications table in the Side Effects section). The surgery-related rule is critical: do not initiate bevacizumab until at least 28 days after major surgery and the wound is fully healed, and withhold for at least 28 days before elective surgery (FDA PI).

Pharmacology of Bevacizumab

Mechanism of Action

Bevacizumab is a recombinant humanised IgG1 monoclonal antibody that selectively binds to human vascular endothelial growth factor A (VEGF-A) with high affinity, preventing its interaction with the VEGF receptors Flt-1 (VEGFR-1) and KDR (VEGFR-2) on the surface of endothelial cells. VEGF-A is the principal mediator of tumour angiogenesis, and its neutralisation by bevacizumab leads to regression of existing tumour microvasculature, normalisation of remaining tumour vessels (improving chemotherapy delivery), and inhibition of new blood vessel formation. The resulting reduction in tumour perfusion and interstitial pressure contributes to the enhanced cytotoxic effect observed when bevacizumab is combined with standard chemotherapy. Bevacizumab does not directly kill tumour cells; its anti-cancer activity is entirely mediated through its effects on the tumour vasculature and microenvironment.

Primary reasons: Haemorrhage, GI perforation, hypertension, proteinuria, wound complications, thromboembolic events
HCC (IMbrave150)
4.9% haemorrhage-related d/c
Key reasons: Haemorrhage (4.9%) and elevated transaminases (0.9%)
GI Perforation: Highest-Risk Populations

The incidence of GI perforation is highest in patients with a history of prior pelvic radiation (up to 3%) and in patients with ovarian cancer who have evidence of recto-sigmoid involvement. Patients should be carefully assessed for signs of GI perforation (abdominal pain, nausea, vomiting, constipation, fever) and the diagnosis should be suspected in any bevacizumab-treated patient presenting with an acute abdomen. Bevacizumab must be permanently discontinued if perforation occurs.

Contraindications & Cautions for Bevacizumab

Absolute Contraindications

  • Squamous cell NSCLC — fatal pulmonary haemorrhage rate of 31% in clinical trials; bevacizumab is only approved for non-squamous histology.
  • Recent haemoptysis ≥2.5 mL (half teaspoon) of red blood — FDA PI explicitly prohibits use.
  • Active serious haemorrhage — bevacizumab exacerbates bleeding; contraindicated with ongoing Grade 3–4 haemorrhage.

Relative Contraindications (Specialist Input Recommended)

  • Planned major surgery within 28 days — increased wound healing complications (15% vs. 4%); must be withheld pre-operatively and not restarted until full wound healing.
  • Recent major surgery (<28 days) or unhealed surgical wound — do not initiate until wound is fully healed.
  • Known ovarian cancer with recto-sigmoid involvement or clinical bowel obstruction — highest GI perforation risk.
  • Significant pre-existing cardiovascular disease (recent MI, unstable angina) — increased ATE risk, particularly in patients >65 years with history of arterial thromboembolism.
  • Pregnancy — teratogenic in animal studies; effective contraception required during and 6 months after treatment.

Use with Caution

  • Elderly patients (≥65 years) — increased risk of Grade 3–5 ATE and Grade 3–4 proteinuria.
  • Pre-existing hypertension — bevacizumab worsens hypertension; ensure adequate BP control before initiating.
  • Patients with diabetes — increased ATE risk in combination with other risk factors.
  • HCC with high variceal bleeding risk — patients with variceal bleeding within 6 months, untreated or incompletely treated varices, or high bleeding risk were excluded from trials.
FDA Class-Wide Safety Advisory VEGF Pathway Inhibitors: Vascular Toxicity Profile

All VEGF-targeted agents share a class-wide risk profile including hypertension, proteinuria, haemorrhage, arterial and venous thromboembolism, wound healing complications, and GI perforation. These risks are mechanistically linked to VEGF pathway inhibition and apply to bevacizumab and all biosimilar products. Note: the bevacizumab boxed warning was removed in June 2019, but the serious adverse event profile remains unchanged and requires vigilant monitoring.

Patient Counselling for Bevacizumab

Purpose of Therapy

Bevacizumab works by blocking a protein (VEGF) that tumours need to build new blood vessels. By cutting off the tumour’s blood supply, it helps chemotherapy work more effectively. It is given as a drip (IV infusion) alongside other cancer treatments and continues for as long as the cancer responds and side effects remain manageable.

How to Receive Treatment

Infusions are given every 2 or 3 weeks depending on the cancer type. The first infusion takes about 90 minutes, and if tolerated, subsequent ones can be shortened to 30 minutes. Regular blood pressure checks and urine tests are needed throughout treatment. No dose reductions are used; if serious side effects occur, the drug is withheld or stopped entirely.

High Blood Pressure
Tell patientBlood pressure will be checked regularly. Many patients develop high blood pressure during treatment, which is usually manageable with medication. Home blood pressure monitoring may be recommended.
Call prescriberFor severe headache, visual disturbances, confusion, or chest pain — these may indicate dangerously high blood pressure or a rare neurological complication (PRES).
Bleeding Risk
Tell patientNosebleeds are very common and usually mild. However, bevacizumab can increase the risk of more serious bleeding. Report any unusual bruising, blood in stool or urine, coughing up blood, or heavy menstrual bleeding.
Call prescriberImmediately for any coughing up of blood, blood in vomit, black tarry stools, sudden severe headache, or any signs of heavy or uncontrolled bleeding.
Abdominal Symptoms (GI Perforation Risk)
Tell patientA rare but serious side effect is a small tear in the bowel wall. Any new or worsening abdominal pain, especially with fever, nausea, or vomiting, needs urgent evaluation.
Call prescriberUrgently for sudden severe abdominal pain, fever with abdominal symptoms, or inability to pass gas or stool — these may indicate a surgical emergency.
Surgery & Wound Healing
Tell patientBevacizumab slows wound healing. Inform all healthcare providers (including dentists) that you are taking this medication before any planned procedures. Treatment must be stopped at least 28 days before surgery.
Call prescriberIf any wound shows signs of infection, delayed healing, opening, or unusual discharge.
Fertility & Pregnancy
Tell patientBevacizumab can harm an unborn baby and may affect fertility in women of childbearing age, with a significant risk of ovarian failure. Use effective contraception during treatment and for 6 months after the last dose. Discuss fertility preservation options before starting treatment.
Call prescriberImmediately if pregnancy is suspected or confirmed during treatment or within 6 months of the last dose.
