Surgery:

Surgery for ovarian cancer uses laparotomy, a major abdominal operation. It is the primary diagnostic tool for ovarian cancer and also plays a role in treatment. Complete surgical intervention includes the following:

• Surgical staging (examining all tissues and organs in the pelvic cavity for accurate assessment of the disease stage).
• Debulking (removal of as much of the cancerous tissue as possible). This is an important component of ovarian cancer management and should be performed by a surgeon trained in cancer surgery techniques.

Patients with ovarian cancer should see a qualified gynecologic oncologist (a surgical specialist in female reproductive cancers) and a qualified medical oncologist with special expertise in the chemotherapeutic management of gynecologic cancer. Studies indicate that it is best for patients, especially those with advanced-stage ovarian cancer, to receive care at medical centers that specialize in cancer treatment and surgery.

Surgical Staging

Surgical staging includes biopsies of the following:

• The undersurface of the diaphragm
• The omentum (the fatty layer that covers and pads organs in the abdomen)
• Sometimes lymph nodes along the abdominal aorta

An abdominal wash is performed by injecting a salt solution into the abdominal cavity to facilitate microscopic detection of cancerous cells not visible to the naked eye. The surgeon then evaluates the pelvis and abdomen and removes suspected cancer tissue. The entire affected ovary is usually removed (oophorectomy) during surgical staging if the surgeon believes it might be cancerous. The tissue is sent to a laboratory for an immediate evaluation called a frozen section diagnosis. The doctor will also examine the bowel and bladder for cancer invasion.

Preservation Surgery in Premenopausal Women with Early Cancer

If the tumor is in an early stage on one ovary and a young woman wants to retain her ability to have children, the surgeon may be able to remove only the affected ovary and perform surgical staging. Chemotherapy follows in selected patients. Studies indicate that in carefully selected young patients, many can expect normal fertility afterward. However, most women with ovarian cancer are not candidates for this procedure.

Total Hysterectomy and Bilateral Salpingo-Oophorectomy and Debulking

The goal of surgery is to remove as much of the tumor as possible for improving symptoms and increasing the effectiveness of chemotherapy. The surgery itself is typically performed as follows:

• In premenopausal women in later stages, and in all postmenopausal women, the surgeon usually removes the uterus (a hysterectomy) and both ovaries and fallopian tubes (a bilateral salpingo-oophorectomy).
• In addition, the surgeon usually removes the omentum (omentectomy), any growths on the diaphragm and intestine, and possibly certain lymph nodes (lymphadenectomy).

If surgical staging reveals that the cancer has invaded the bowel, a portion of the intestine may have to be removed as well.

Postoperative Care in the First Few Days after Hysterectomy

Postoperative Care. If possible, a patient should ask a family member or friend to help out for the first few days at home. The following are some of the precautions and tips for postoperative care:

• For 1 - 2 days after surgery, the patient is given medications to prevent nausea and painkillers to relieve pain at the incision site.
• As soon as the doctor recommends it, usually within a day of the operation, the patient should get up and walk in order to help prevent pneumonia, reduce the risk of blood-clot formation, and to hasten recovery.
• Walking and slow, deep breathing exercises may help to relieve gas pains, which can cause major distress for the first few days.
• Coughing can cause pain, which may be reduced by holding a pillow over a surgical abdominal wound or by crossing the legs after vaginal surgery.
• Patients are advised not to lift heavy objects (including small children), not to douche or take baths, and not to climb stairs or drive for several weeks.
• For the first few days after surgery, many women weep frequently and unexpectedly. These mood swings may be due to depression from the loss of reproductive capabilities and form abrupt changes in hormones, particularly if the ovaries have been removed.

Patients should talk to their doctors about when they can start exercise programs that are more intense than walking. The abdominal muscles are important for supporting the upper body, and recovering strength may take a long time. Even after the wound has healed, the patient may experience an on-going feeling of overall weakness. Some women do not feel completely well for as long as a year. Others may recover in only a few weeks.

Complications Following the Procedure. Minor complications after hysterectomy are very common:

• Women may develop minor and treatable urinary tract infections.
• There is usually light vaginal bleeding and pain after the operation, which can be well-controlled with pain medications.

Treating Menopausal Symptoms and Premature Menopause. After removal of the ovaries, premenopausal women usually have hot flashes, a symptom of menopause. Symptoms come on abruptly and may be more intense than those of natural menopause. Symptoms include hot flashes, vaginal dryness and irritation, and insomnia. A significant number of women gain weight.

The most important complications that occur in women who have had their ovaries removed are due to estrogen loss, which places women at risk for osteoporosis (loss of bone density) and a possible increase in risks for heart disease. Women have typically taken hormone replacement therapy (HRT) after surgery if their ovaries have been removed. There have been concerns however about health risks, including the risk for breast cancer and stroke, which have now limited its use. Risks in premenopausal women who have had a hysterectomy have not yet been clarified. Several nonhormonal drugs, however, can help protect both bones and heart.

Surgery for Bowel Obstruction

Bowel obstruction is common in ovarian cancer. Surgery can be very helpful for selected patients with this problem.
