Ovarian cancer remains the most lethal gynecologic malignancy, responsible for more than 12,000 deaths and nearly 20,000 new diagnoses in the United States last year, according to American Cancer Society estimates. While incidence and mortality have declined modestly over the past two decades, the five-year survival for epithelial ovarian cancer (EOC) – the most common histology – remains stubbornly around 50%. For patients with metastatic disease, survival plummets to roughly 30%.

“Unfortunately, about 75% of patients are diagnosed with stage III or IV disease, which carries a high recurrence risk,” states Joel Cardenas Goicoechea, M.D., MBA, a board-certified gynecologic oncologist recently named Medical Director of Gynecologic Oncology at Cleveland Clinic in Florida. “We’re constantly reevaluating how to improve outcomes without compromising oncologic safety.”

One open question being explored is the most effective way to surgically remove all visible pelvic, abdominal, and retroperitoneal disease in cases of advanced ovarian cancer.

Maximal debulking

Traditionally, patients with advanced-stage ovarian cancer have undergone open cytoreductive surgery, an operation that can involve a midline vertical incision from the xiphoid process to the symphysis pubis. “Our goal is to achieve maximal tumor debulking, a known prognostic factor in ovarian cancer survival,” says Dr. Cardenas.

However, with advances in surgical technology and chemotherapy regimens, the question of whether minimally invasive surgery (MIS) – laparoscopy or robotic surgery – can safely achieve the same oncologic endpoints has become increasingly relevant.

Over the past two decades, MIS has become standard of care in other cancers – notably endometrial cancer. Randomized controlled trials like GOG LAP2 and LACE demonstrated not only comparable survival outcomes, but also significant improvements in perioperative morbidity, pain, length of stay and quality of life.

Yet, as Dr. Cardenas cautions, “We learned the hard way not to generalize these findings across all gynecologic cancers.”

Evidence over enthusiasm

This philosophy underpins Dr. Cardenas’ support for the Laparoscopic Cytoreduction After Neoadjuvant Chemotherapy (LANCE) trial, an international, multicenter, phase III study comparing MIS versus open interval cytoreduction following neoadjuvant chemotherapy in patients with stage IIIC-IV ovarian, primary peritoneal, or fallopian tube cancer.

Study participants receive three to four cycles of chemotherapy prior to undergoing either open surgery or MIS, followed by additional standard-of-care chemotherapy. Investigators will assess disease free survival as the primary endpoint, as well as overall survival, perioperative outcomes, and differences in health-related quality of life.

In the trial’s feasibility phase, which enrolled 100 women, complete gross resection was achieved in 88% of evaluable patients undergoing MIS (laparoscopic or robotic), compared to 83% in the open group. Based on these findings, the definitive phase is now underway to assess whether MIS can match or potentially improve oncologic outcomes.

Cleveland Clinic Weston Hospital is one of two enrollment sites in Florida and 19 internationally. The team’s first enrolled patient was randomized to open surgery, reports Dr. Cardenas. “I would encourage all eligible patients to consider enrollment. This is how we advance the field,” he adds.

The rise of preventive surgery

Dr. Cardenas also reports a growing number of patients – particularly those with a family history of ovarian cancer – seeking risk-reducing salpingo-oophorectomy following genetic testing. He notes that about 20% of ovarian cancers have a hereditary component, most commonly involving BRCA1 and BRCA2 mutations.

“I perform all prophylactic surgeries robotically,” he says. “Patients go home the same day, experience less pain and recover faster.”

Dr. Cardenas credits his early experience with robotic technology for his proficiency with the approach. “I started doing robotic surgery in 2006, just after the FDA cleared the platform. The latest technology allows seven degrees of motion, 3D visualization and fine dissection, which is particularly helpful in deep pelvic spaces.”

Comprehensive care

Dr. Cardenas underscores that ovarian cancer requires a multidisciplinary approach. In addition to a gynecologic oncologist, medical oncologist and radiation oncologist, patients may need the care of a liver, colorectal and/or upper abdominal subspecialist. “At Cleveland Clinic Weston Hospital, we have that multidisciplinary capacity and are able to provide truly comprehensive care,” he states.

His team also performs HIPEC (hyperthermic intraperitoneal chemotherapy) for appropriate candidates – typically those receiving neoadjuvant chemotherapy followed by interval debulking.

With only 1,700 new ovarian cancer cases diagnosed each year in Florida, having access to high-volume, experienced centers is critical. Weston Hospital is a regional referral center for patients with ovarian cancer across all Cleveland Clinic locations in Florida.
