Cervical Cancer: Staging, Clinical Presentation, and Management Options

Introduction and Clinical Presentation of Cervical Cancer

Cervical cancer remains a major public health challenge across Nigeria, heavily affecting women who often present late to healthcare facilities. The primary culprit is persistent infection with high-risk types of the human papillomavirus (HPV), particularly types 16 and 18. Early stages are frequently asymptomatic, which explains why routine screening is so vital.

When symptoms eventually appear, they signal that the disease has progressed locally. Midwives must recognize these classic warning signs during antenatal, postnatal, or general gynae clinic visits:

• Post-coital bleeding: Bleeding that occurs immediately after sexual intercourse, often the earliest noticeable sign.
• Intermenstrual bleeding: Unpredictable bleeding between normal menstrual periods.
• Post-menopausal bleeding: Any vaginal bleeding occurring in a woman who has gone through menopause for at least one year.
• Abnormal vaginal discharge: Watery, blood-tinged, or foul-smelling discharge caused by tumor necrosis and infection.
• Pelvic or lower back pain: Advanced signs indicating the cancer has spread to pelvic walls or nerve roots.

Diagnostic Workup and FIGO Staging

Accurate staging dictates treatment choices and prognosis. Cervical cancer is staged clinically using the FIGO (International Federation of Gynecology and Obstetrics) system. In low-resource Nigerian settings, staging relies heavily on clinical examination rather than expensive imaging like MRI.

The diagnostic process typically involves:

1. Visual Inspection with Acetic Acid (VIA) and Lugol's Iodine (VILI) for initial screening or low-cost community checks.
2. Colposcopy and Directed Biopsy: The definitive method to confirm the diagnosis histologically.
3. Clinical Staging Examinations: Examination under anesthesia (EUA), cystoscopy, and sigmoidoscopy to check if the bladder or rectum are involved in advanced stages.

Midwives should note that staging is strictly clinical; changes found on imaging do not alter the assigned FIGO stage.

Surgical Management Options by Stage

Surgery is most effective when cervical cancer is caught early, specifically in Stage IA through early Stage IIA. The goal is complete tumor removal with clear surgical margins while preserving urinary and sexual function where possible.

Common surgical procedures include:

• Conization (Cone Biopsy): Used for microinvasive disease (Stage IA1) in young women who still desire future fertility.
• Simple Hysterectomy: Removal of the uterus, sometimes considered for very early stage IA1 without lymphovascular space invasion.
• Radical Hysterectomy (Wertheim's Operation): Involves removing the uterus, cervix, upper vagina, and surrounding parametrial tissues along with pelvic lymph node dissection.

Many patients in Nigeria present too late for surgery. When cancer has invaded the pelvic sidewall, radical surgery becomes ineffective and harmful, making radiation the preferred primary modality.

Role of Radiotherapy and Chemotherapy

For locally advanced cervical cancer—spanning stages IIB through IVA—radiotherapy combined with chemotherapy is the gold standard of treatment. Surgery at these advanced stages often leaves behind cancer cells and carries high surgical morbidity.

Concurrent chemoradiation involves giving systemic chemotherapy (most commonly cisplatin) alongside external beam radiotherapy (EBRT) to sensitize cancer cells to the radiation rays. This is followed by brachytherapy, which places a radioactive source directly inside the uterine cavity and vagina to deliver a high local dose to the tumor while sparing surrounding healthy tissues like the bladder and rectum.

Managing treatment side effects is a crucial part of care. Patients frequently experience radiation proctitis, cystitis, and skin irritation. Midwives help monitor nutritional status and encourage adequate hydration to reduce urinary tract complications during this intensive therapy.

Palliative Care and Symptom Relief

Because a large proportion of Nigerian women present with terminal or metastatic Stage IV cervical cancer, palliative care is an essential pillar of management. The focus shifts from curing the disease to maximizing comfort, dignity, and quality of life.

Key areas of palliative symptom management include:

• Pain control: Following the WHO analgesic ladder, utilizing non-opioids, weak opioids, and strong opioids like oral morphine as pain escalates.
• Managing bleeding and discharge: Using local hemostatic agents, gentle packing, or short courses of palliative radiotherapy to control foul-smelling or continuous bleeding.
• Relieving urinary obstruction: Managing hydronephrosis and renal failure through percutaneous nephrostomy or double-J ureteric stenting when appropriate.
• Psychosocial support: Addressing depression, anxiety, and the social stigma often attached to foul-smelling or debilitating gynecological cancers.

The Midwife's Role in Prevention and Survivorship

Midwives occupy a frontline position in combating cervical cancer through primary prevention, early screening, and long-term survivorship support. Prevention is far more cost-effective and successful than treating advanced disease.

Primary prevention centers on HPV vaccination for young adolescent girls before sexual debut, as well as public health education on safe sexual practices and smoking cessation. Secondary prevention involves scaling up screening programs using VIA or Pap smears in local health centers.

For survivors, midwives provide empathetic follow-up care, addressing issues such as sexual dysfunction, lymphedema, menopausal symptoms induced by treatment, and regular monitoring for cancer recurrence. Creating a supportive, non-judgmental environment encourages women to seek help early.
