Cervical Cancer

Pathology

Cervical cancer, also known as cervical carcinoma, is a malignancy that develops in the cervix, the lower part of the uterus connecting the uterine cavity to the vagina.

Thanks to organized screening programs and vaccination against Human Papillomavirus (HPV), the incidence of cervical cancer has significantly declined over recent decades. The ultimate goal of the scientific community is the complete elimination of this disease as a public health problem.

Today, early diagnosis and advances in treatment allow cervical cancer to be managed with a high likelihood of cure, particularly when detected at an early stage. Regular screening and HPV vaccination remain the most effective strategies for prevention and early detection.

Types

Cervical cancers are classified according to the type of cells from which they originate.

The two most common histological subtypes are:

  • Squamous cell carcinoma (approximately 85%). Arises from the squamous cells lining the exocervix, the outer portion of the cervix. It is most commonly associated with HPV types 16, 18, 58, 33, and 45.
  • Adenocarcinoma (approximately 10–12%). Originates from the glandular cells of the endocervix, the inner portion of the cervix. It is most commonly associated with HPV types 16, 18, 45, 31, and 33.

Less common histological variants include:

  • Adenosquamous carcinoma (approximately 3–5%)
  • Adenoid cystic carcinoma
  • Undifferentiated carcinoma

Accurate histological classification is essential for defining the most appropriate and personalized treatment strategy.

The Numbers in Italy

According to the AIRTUM registry (Italian Association of Cancer Registries), 2,382 new cases of cervical cancer were diagnosed in Italy in 2024.

Although relatively uncommon overall, cervical cancer remains one of the most frequent malignancies among younger women, accounting for approximately 4% of cancers diagnosed in this population and ranking among the most common tumors in women under 50 years of age.

Risk Factors

The principal risk factor for cervical cancer is persistent infection with Human Papillomavirus (HPV), which is responsible for the vast majority of cases.

Additional risk factors include:

  • Cigarette smoking
  • Family history of cervical cancer
  • Long-term use of oral contraceptives
  • Low socioeconomic status

It is important to note that most HPV infections resolve spontaneously without causing disease. However, when infection persists, precancerous lesions may develop within the cervix and progressively evolve into cancer if left untreated. This underscores the importance of prevention through HPV vaccination and regular screening with Pap tests or HPV-DNA testing.

Symptoms

In its early stages, cervical cancer is often asymptomatic.

When symptoms occur, they may include:

  • Abnormal vaginal bleeding, particularly after sexual intercourse, between menstrual periods, or after menopause
  • Unusual vaginal discharge, sometimes watery or malodorous
  • Pain during sexual intercourse

These symptoms are not specific to cervical cancer and may be caused by a variety of benign conditions. Nevertheless, they should always be evaluated by a gynecologist.

Diagnosis and Evaluation

Because cervical cancer may not cause symptoms in its early stages, it is frequently detected through routine screening.

The diagnostic pathway typically includes:

  • Pap test and HPV-DNA test:These screening examinations can identify precancerous lesions and early-stage disease before symptoms develop.
  • Colposcopy: If screening results are abnormal, colposcopy allows detailed visualization of the cervix using a specialized magnifying instrument.
  • Biopsy: During colposcopy, tissue samples may be collected from suspicious areas for histopathological evaluation.
  • Conization: In selected cases, removal of a cone-shaped portion of the cervix may be required to obtain a definitive diagnosis and evaluate the extent of disease.

Following histological confirmation, additional investigations are performed to determine disease stage and guide treatment planning.

These may include:

  • Transvaginal and transabdominal pelvic ultrasound, to assess local disease extension and relationships with adjacent organs
  • Contrast-enhanced pelvic MRI, to evaluate local tumor extent and possible lymph node involvement
  • Contrast-enhanced CT scan of the chest, abdomen, and pelvis, to identify disease beyond the pelvis

In patients with locally advanced disease, further investigations may include:

  • 18F-FDG PET/CT: Useful for characterizing suspicious lesions and identifying distant metastases.
  • Examination under anesthesia: Recommended by the International Federation of Gynecology and Obstetrics (FIGO), this procedure enables comprehensive assessment of local disease extension by the gynecologic oncologist. Evaluation may include examination of the vaginal fornices, parametrial tissues, urethra, and bladder, as well as cystoscopy. In selected cases, diagnostic laparoscopy may also be performed.

Stage Classification

The FIGO staging system classifies cervical cancer from Stage I, where disease is confined to the cervix, to Stage IV, where it has spread beyond the pelvis or to distant organs.

Accurate staging is essential for selecting the most appropriate treatment and ensuring individualized patient care.

Therapies

Treatment depends on multiple factors, including disease stage, tumor characteristics, age, overall health status, and the patient’s reproductive goals.

Management may involve one or more of the following approaches:

Early Cases

In carefully selected patients with very early-stage disease, fertility-sparing and less invasive procedures may be considered:

  • Conization: removal of a cone-shaped portion of the cervix containing the lesion, which may be sufficient for diagnosis and treatment in selected cases
  • Trachelectomy: removal of the cervix while preserving the uterine body, offering the possibility of maintaining fertility in appropriately selected patients

Early Stage Cancer (Confined to the Cervix)

For patients with early-stage cervical cancer, surgery is generally the primary treatment option. Depending on the characteristics and extent of the disease, surgical management may include:

  • Radical hysterectomy, involving removal of the uterus, surrounding supporting tissues (parametrium and paracervix), and, in selected cases, the ovaries
  • Sentinel lymph node biopsy, performed alone or in combination with pelvic lymphadenectomy (removal of pelvic lymph nodes) to assess potential lymph node involvement

Based on the final pathological findings and the presence of specific risk factors, adjuvant radiotherapy or chemoradiotherapy may be recommended after surgery to reduce the risk of recurrence.

Evidence from the landmark Laparoscopic Approach to Cervical Cancer (LACC) trial has shown that, for most patients with early-stage cervical cancer, the preferred surgical approach is open surgery (laparotomy) rather than minimally invasive surgery. Minimally invasive approaches may still be considered in carefully selected cases and according to individual clinical circumstances.

Locally Advanced Disease

For patients with locally advanced cervical cancer, the standard treatment is a combined approach that integrates radiotherapy and chemotherapy.

Treatment typically includes:

  • External beam radiotherapy (EBRT), directed at the tumor and surrounding areas at risk of disease spread
  • Concurrent cisplatin-based chemotherapy, administered during radiotherapy to enhance its effectiveness
  • Brachytherapy, an internal radiation therapy technique in which specialized applicators are placed within the uterus and cervix to deliver high-dose radiation directly to the tumor while minimizing exposure to surrounding healthy tissues

This multimodal approach aims to maximize local disease control and improve long-term outcomes.

Immunotherapy

Immunotherapy represents an important therapeutic option in selected patients with cervical cancer, particularly because the PD-L1 protein, a target of several immunotherapeutic agents, is expressed in more than 90% of cases.

The most commonly used immunotherapy drugs include:

  • Pembrolizumab
  • Atezolizumab
  • Nivolumab
  • Ipilimumab in combination with Nivolumab

These treatments work by enhancing the body’s immune response against cancer cells, helping the immune system recognize and eliminate tumor tissue more effectively.

Immunotherapy has expanded treatment opportunities, particularly for patients with advanced, recurrent, or metastatic cervical cancer, and may be used alone or in combination with other therapies depending on the clinical setting and tumor characteristics.

According to the recommendations of the European Society of Gynaecological Oncology (ESGO), follow-up generally includes:

  • A gynecological examination every 3 to 6 months during the first two years after treatment, followed by every 6 months for the subsequent three years
  • An annual Pap test
  • Imaging studies, such as ultrasound, CT, or MRI, and blood tests when clinically indicated, according to a schedule determined by the treating physician

Follow-up plans may be tailored to the individual patient based on disease characteristics, treatment received, and specific clinical needs.

Multi Disciplinary Team

Every cancer requires a multidisciplinary approach at all stages of disease management. At the Candiolo Cancer Institute, this is provided by a team of specialists from various clinical and surgical departments, known as the GIC, Interdisciplinary Care Group (or MDT). The GIC ensures that each patient is supported throughout the diagnostic and therapeutic process, including arranging and coordinating examinations and maintaining communication with the patient and their family.

For each patient, the GIC (MDT) defines and shares a personalized care pathway based not only on the type and stage of the tumor but also on the patient’s individual characteristics. The goal is to achieve the best possible outcomes both oncologically and functionally, while maintaining a high quality of life.

The Group also collaborates closely with the Institute’s researchers to provide patients with rapid access to the latest innovations in screening, diagnosis, and treatment.
