Tumors of the ovary

Pathology

It is a cancer that affects the ovaries, organs of the female genital system responsible for the production of oocytes and female sex hormones, such as estrogen and progesterone. Ovarian cancer arises from the uncontrolled growth of ovarian cells. In most cases it involves epithelial cells, which line the organ, but it can also originate from germ or stromal cells, albeit more rarely.

It is an often silent disease because in its early stages it may not give obvious symptoms, which is why it is often diagnosed in more advanced stages. If detected early, however, ovarian cancer can be successfully treated.

The numbers in Italy

In 2024, according to the AIRTUM (Italian Association of Cancer Registries) registry, ovarian cancer in Italy recorded about 5,423 new diagnoses.

Types

Ovarian cancer can develop from different cells in the ovary:

  • Epithelial tumors: these are the most common (90% of cases) and originate from the outer lining of the ovary:
    • Type 1: low-grade serous, mucinous, endometrioid and clear cell tumors
    • Type 2: high-grade serous tumors, the most frequent.
  • Borderline tumors: tumors with a low degree of malignancy, often diagnosed in early stages and at a young age, which can be treated with conservative surgery;
  • Stromal or sex cord tumors: rare, originating from the connective tissue of the ovary and producing female hormones. They include granulosa, granulosa-teca and Sertoli-Leydig tumors;
  • Germ cell tumors: rare (5% of cases), arise from the cells that produce oocytes and occur most often in women under 30 years of age. Main types: teratomas, dysgerminomas, endodermal sac tumors, and choriocarcinomas.

Symptoms

Ovarian cancer in the early stages often causes no symptoms, so early diagnosis can be difficult. However, there are some signs to watch out for:

  • Bloated abdomen or feeling of a full belly (meteorism);
  • Frequent need to urinate;
  • Abdominal or pelvic pain;
  • Vaginal bleeding;
  • Constipation or diarrhea;
  • Unusual feeling of fatigue;
  • Nausea or loss of appetite (in more advanced stages);
  • Sense of fullness immediately after starting to eat.

If the symptoms appear together or in rapid succession, it is a good idea to consult a gynecologist.

Risk factors

The main risk factors for ovarian cancer are:

  • Early menarche or late menopause;
  • First pregnancy over the age of 35;
  • pelvic inflammatory disease;
  • Not having had children;
  • family history;
  • genetic mutations(BRCA1-2, Lynch syndrome);
  • endometriosis;
  • polycystic ovary syndrome (PCOS)

Instead, the protective factors arebreastfeeding, an age of less than 25 years at first pregnancy, and the use of oral contraceptives.

Diagnosis and examination

To date, there are no diagnostic procedures with adequate sensitivity and specificity to allow early detection, and consequently, there is no effective screening program for malignant ovarian cancer.
In case of clinical suspicion, the physician will prescribe second-level investigations, which normally include:

  • Tumor marker assay (Ca125, CA19.9, CA15.3, CEA, alpha-feto protein);
  • Level 2 transvaginal ultrasound performed by an experienced operator;
  • Computed tomography (CT) with contrast medium including the chest, abdomen, and pelvis.

If further diagnostic investigation is needed, a Magnetic Resonance Imaging (MRI) of the pelvisand/or a total body PET scan may also be performed.

Definitive diagnosis of ovarian cancer is confirmed only byhistological examination after surgery.

Therapies

L’Ovarian Cancer Center is a highly specialized referral center offering a multidisciplinary approach to patients with ovarian cancer. Treatment of ovarian cancer is individualized and includes both surgery and medical-chemotherapy treatment.

In selected cases and for patients who wish to have children in the future, fertility preservation treatment, called fertility sparing surgery, can be offered. This surgery removes the tumor while preserving part of the ovary and/or uterus, when possible, to maintain the possibility of subsequent conception. The choice of this option is evaluated by the multidisciplinary team, considering the stage of the disease, the type of tumor, and the patient’s oncologic safety.

Medical therapy of ovarian cancer after or before surgery includes systemic antiblastic chemotherapy and maintenance therapies that include cutting-edge biologic therapies with monoclonal antibodies and oral therapies such as PARP inhibitors. The choice of medical therapy is made with molecular diagnostic assessments.

Early stage ovarian cancer

When the disease is limited to one or both ovaries, surgery may include:

  • Bilateral hysteronephrectomy: removal of uterus and ovaries to completely remove tissue in which the disease could develop;

  • peritoneal staging (e.g., omentectomy): removal of the omentum, an abdominal tissue that may be the site of any hidden cancer cells;

  • Retroperitoneal staging (pelvic and lumbar-aortic lymphadenectomy): removal of lymph nodes near the uterus and along the aorta to see if the disease has spread.

Surgical access:

  • Laparotomy: opening of the abdomen to operate directly on organs;

  • operative laparoscopy: minimally invasive surgery through small incisions (about 5 mm), which reduces pain and recovery time.

Advanced ovarian cancer

When the disease extends beyond the ovaries, the diagnostic and therapeutic course involves several steps:

  • diagnostic laparoscopy to directly assess the spread of disease in the abdomen, avoiding relying solely on radiological examinations. Diagnostic laparoscopy makes it possible to observe tumor distribution and take tissue samples(biopsies) for immediate histologic examination, which is useful in confirming the diagnosis during surgery;
  • cytoreducibility assessment: through scoring scales such as Predictive Index Value (PIV) or Fagotti score, the surgical possibility of optimal cytoreduction (excision of all macroscopically visible disease or with residual tumor less than 1cm) is assessed;
  • in case of a favorable score, primary debulking surgery- PDS-is performed during the same surgery. Cytoreductive surgery (the removal of all macroscopically visible tumor) therefore involves the removal of the uterus and ovaries, omentum, lymph nodes if pathologically increased in volume, and all tissues or organs affected by the disease;
  • if the tumor is not cytoreducible, targeted biopsies are performed to accurately define the molecular and genetic type of the disease and select the most effective therapies. Patients are then started on neoadjuvant chemotherapy to reduce abdominal disease, and normally, after 3 cycles of therapy, surgery is rescheduled.

Ongoing support

At our institute, we ensure constant support before, during and after treatment to accompany each patient throughout the entire course of treatment and recovery.

Management of emergencies and side effects

The cancer patient is often a fragile patient, who needs help and support in her disease journey: when she experiences an ailment, whether related to the disease or a side effect of therapy, she needs to be able to receive a specialist’s opinion quickly, through a “fast track.”

For this reason, at the Candiolo Institute there is an assistance service every day, Monday through Friday from 8 a.m. to 5 p.m.: just call the secretary of the Oncology Day Hospital (011 993 3775) reporting the need for an urgent consultation, and the patient is quickly contacted by his or her specialist doctor.

Psychological support

The impact of cancer in a person’s life also affects the psychological sphere: falling ill with cancer is in fact always a traumatic event that affects all dimensions of the person and can generate anxiety, fear, anger, depression.

At the Candiolo Institute, alongside cutting-edge therapies, the treatment and care pathway always includes a qualified psycho-oncological support that helps the patient cope positively not only with treatment but also with the delicate phase of physical and psychological recovery.

It is also possible to participate in support groups psychological to compare with other people who have gone through or are going through the same experience.

Direct line to specialists

To ensure timely and direct support and receive timely answers to concerns and questions, a dedicated support service is in place at the Candiolo Institute for all patients.

From Monday to Friday, from 8 a.m. to 5 p.m., you can contact the secretariat of the oncology day hospital at 011.993.3775, reporting the need for urgent consultation.

The patient will be quickly put in touch with his or her medical specialist, to receive clear answers and immediate support.

Continuing and palliative care

The cancer patient is a person with complex needs that requires multidisciplinary support not only for the cancer disease, but also for all related issues.

At the Candiolo Institute, patients who need or require it have access to specialists in different areas to receive nutritional support, physical therapy, pain therapy and management of other associated conditions.

Social work

The Social Service Department of the Candiolo Institute conducts information and orientation interviews to patients and their families on how to access services in the area and how to obtain welfare and social security benefits provided by law (disability, benefits for aids and prostheses, work leave, etc.).

The service operates on Wednesdays and Fridays from 9 a.m. to 1 p.m. (phone: 011 9933059).

Follow up

With the conclusion of the course of treatment, the follow-up period begins during which, through a series of examinations and visits, the side effects of the therapies performed and their effectiveness are monitored and the patient’s functional recovery is assessed.

Follow-up visits are especially important to intercept any recurrences early, so that appropriate therapy can be intervened. For the patient, they are also a valuable opportunity for dialogue with her medical specialist.

It is the same specialist physician who schedules follow-up visits, in which the patient’s health condition is assessed and reports of any required tests are viewed.

Interdisciplinary Group

Every cancer requires, in all phases of disease management, a multidisciplinary approach that at the Candiolo Institute is guaranteed by a team of different specialists, belonging to the various clinical and surgical departments of the Institute: this team is called GIC (Interdisciplinary Care Group). The GIC ensures that each patient is taken care of throughout the diagnostic-therapeutic process, including prescribing and booking examinations and communicating with the patient and his or her family members. The GIC defines and shares a personalized care pathway for each patient, based not only on the type and stage of the tumor, but also on the patient’s own characteristics. The goal is to ensure that he or she has the best outcome both oncologically and functionally and the maintenance of a good quality of life.The Group also works closely with researchers at the Institute to ensure that patients have rapid access to the latest research-produced innovations in screening, diagnosis and treatment.

Clinical divisions

The diagnostic and therapeutic pathway of cervical ‘ovarian cancers at Candiolo involves several clinical divisions, including:

Clinical studies

Researchers at the Candiolo Institute are currently involved in numerous national and international projectson gynecological cancers.
