Cervical Cancer: Complications & Clinical Risks

Cervical cancer is caused primarily by persistent HPV infection and is highly preventable with vaccination and regular Pap smears. It develops in the cervix and is one of the most common cancers in women globally.

Overview of Major Complications

Oncological and haematological conditions generate complications from direct tumour invasion, paraneoplastic effects, cancer treatment toxicities, and the consequences of immune and haematopoietic failure. Treatment-related complications — myelosuppression, cardiotoxicity, neuropathy, and infertility — represent a growing clinical challenge as cancer survivorship increases. Haematological cancers cause haematopoietic failure, immunosuppression, and organ infiltration, while solid tumours generate complications from local invasion, metastatic spread, and systemic metabolic effects.

Early Complications

  • ⚠Febrile neutropaenia — oncological emergency; broad-spectrum IV antibiotics within 1 hour
  • ⚠Tumour lysis syndrome — from treatment of high-burden haematological malignancies; hyperkalaemia, hyperuricaemia
  • ⚠Superior vena cava syndrome — mediastinal malignancy compresses SVC; facial oedema, breathlessness
  • ⚠Spinal cord compression — from vertebral metastasis; back pain with neurological deficit; MRI urgently
  • ⚠Venous thromboembolism — 4–7× increased risk in active malignancy; Trousseau's syndrome
  • ⚠Anaemia from bone marrow infiltration or haemorrhage — fatigue, reduced exercise tolerance

Long-Term Complications

  • →Chemotherapy-induced peripheral neuropathy — sensory loss, pain, functional limitation; may be permanent
  • →Anthracycline cardiotoxicity — dilated cardiomyopathy months to years after treatment
  • →Secondary malignancy — from radiotherapy, alkylating agents, or topoisomerase inhibitors
  • →Lymphoedema — from lymph node dissection or radiotherapy; chronic swelling and infection risk
  • →Cognitive impairment ('chemo brain') — attention, memory, and processing speed affected
  • →Infertility — from gonadotoxic chemotherapy or pelvic radiotherapy
  • →Hypothyroidism — from neck irradiation; post-thyroidectomy
  • →Bone marrow failure — from cumulative chemotherapy exposure or radiation to marrow sites

Emergency Complications

Immediate clinical action required

  • ✕Febrile neutropaenia — immediate broad-spectrum antibiotics; delay increases mortality significantly
  • ✕Hypercalcaemia of malignancy — IV fluid, bisphosphonate, calcitonin; confusion and renal failure
  • ✕Acute spinal cord compression — IV dexamethasone immediately; MRI and neurosurgical assessment
  • ✕Haemorrhage from thrombocytopaenia — platelet transfusion threshold <10×10⁹/L or active bleeding
  • ✕Tumour lysis syndrome — IV hydration, allopurinol/rasburicase; cardiac monitoring for hyperkalaemia

What Increases Complication Risk

  • ↑Delayed cancer diagnosis — later stage at presentation dramatically reduces treatment options
  • ↑Immunosuppression — increases opportunistic infection risk during and after treatment
  • ↑Non-adherence to treatment protocols — reduces disease control and increases resistance
  • ↑Comorbidities — cardiac disease limits anthracycline use; CKD limits platinum-based therapy
  • ↑Smoking and alcohol — increase treatment toxicity and second malignancy risk
  • ↑Nutritional depletion — impairs treatment tolerance and immune recovery

What Reduces Complication Risk

  • ↓G-CSF prophylaxis in high-risk chemotherapy regimens — reduces febrile neutropaenia incidence
  • ↓Antiemetic regimens (5-HT3 antagonists, dexamethasone, NK1 antagonists) — improve treatment tolerance
  • ↓LMWH thromboprophylaxis — reduces VTE risk in ambulatory cancer patients
  • ↓Cardioprotection during anthracycline therapy — dexrazoxane; echocardiographic monitoring
  • ↓Fertility preservation counselling before gonadotoxic treatment
  • ↓Cancer rehabilitation programmes — improve functional recovery and quality of life

When Urgent Reassessment is Needed

The following signs may indicate a new or worsening complication requiring prompt clinical evaluation:

  • ◆Fever (>38°C) in neutropaenic patient — febrile neutropaenia; IV antibiotics within 1 hour
  • ◆Back pain with leg weakness or bladder/bowel dysfunction — cord compression; emergency MRI
  • ◆Confusion, polydipsia, and polyuria in cancer patient — hypercalcaemia of malignancy
  • ◆Severe breathlessness with raised JVP — SVC syndrome or pericardial effusion
  • ◆Unexplained new bone pain — possible skeletal metastasis; pathological fracture risk
  • ◆Sudden severe bruising or bleeding — thrombocytopaenia; platelet count urgently

Special Populations

Elderly cancer patients: more susceptible to treatment toxicity; comprehensive geriatric assessment before chemotherapy
Children: long-term follow-up critical; growth, endocrine, neurodevelopmental, and cardiac sequelae from treatment
Pregnant women with cancer: treatment delay or modification required; multi-disciplinary oncology-obstetrics team essential
Patients with haematological malignancies: infection risk profile differs; fungal infections require antifungal prophylaxis in prolonged neutropaenia
