Robotic Surgery and Cervical Cancer: Key Considerations in Light of Recent Research

January is Cervical Cancer Awareness Month, an opportunity to raise awareness about prevention, screening, and treatment advances. Robotic-assisted surgery, particularly using the da Vinci Si and da Vinci Xi, has transformed surgical procedures across multiple specialties. However, emerging research, including the Laparoscopic Approach to Cervical Cancer (LACC) trial and a new five-year study from Houston Methodist Hospital, has raised concerns about using minimally invasive radical hysterectomy (MIRH) for early-stage cervical cancer.

This article will explore cervical cancer prevention, treatment options, robotic surgery's role, and why new research urges a shift back to open radical hysterectomy.

What Is Cervical Cancer?

Cervical cancer begins in the cervix, the lower part of the uterus that connects to the vagina. It is most commonly caused by persistent infection with high-risk human papillomavirus (HPV) strains.

Key Risk Factors for Cervical Cancer

• HPV infection (the leading cause)
• Weakened immune system
• Smoking
• Long-term use of birth control pills
• Multiple full-term pregnancies
• A family history of cervical cancer

While cervical cancer was once a leading cause of cancer death among women, regular screenings and HPV vaccinations have dramatically reduced mortality rates.

Why Are Cervical Cancer Screenings Important?

Cervical cancer develops slowly and may not show symptoms in early stages, making screenings critical for early detection and prevention.

Types of Cervical Cancer Screenings

1. Pap Smear (Pap Test) – Identifies precancerous or cancerous cells in the cervix.
2. HPV Test – Detects high-risk HPV strains that cause cervical cancer.

Screening Recommendations

• Women 21-29: Pap test every 3 years
• Women 30-65: Pap test every 3 years, HPV test every 5 years, or co-testing every 5 years
• Women 65+: May discontinue screening if prior results have been normal

Take Action: Get Screened Today

Regular screenings save lives by catching cervical cancer before it becomes advanced. If you or a loved one has not had a recent screening, schedule one today.

How Is Cervical Cancer Treated?

Treatment depends on cancer stage, tumor size, and patient health. Common options include:

• Surgery (including hysterectomy)
• Radiation therapy
• Chemotherapy
• Targeted therapy and immunotherapy (for advanced cases)

For early-stage cervical cancer, surgery is the preferred treatment. However, recent studies suggest that the method of surgery significantly impacts survival outcomes.

The Role of Robotic Surgery in Cervical Cancer: Lessons from the LACC Trial

How Does Robotic-Assisted Surgery Work?

Robotic-assisted surgery is a minimally invasive technique where surgeons use systems like the da Vinci Xi and da Vinci Si to perform procedures through small incisions. The system provides:

• A surgeon-controlled console
• Miniaturized robotic instruments with enhanced dexterity
• A high-definition 3D camera for magnified views

While robotic surgery is widely used in urology, gynecology, and general surgery, its role in cervical cancer treatment has come under scrutiny.

What the LACC Trial Revealed

The Laparoscopic Approach to Cervical Cancer (LACC) trial was a randomized controlled study comparing minimally invasive radical hysterectomy (MIRH)—including robotic-assisted and laparoscopic surgery—to open radical hysterectomy in early-stage cervical cancer patients. The results were unexpected and transformative:

• Minimally invasive surgery had significantly worse outcomes than open surgery.
• Patients undergoing minimally invasive procedures had higher recurrence rates.
• Survival rates were lower for minimally invasive surgery.

These findings led to a major shift in clinical practice, with the National Comprehensive Cancer Network (NCCN) changing its guidelines to recommend open radical hysterectomy over minimally invasive approaches.

New Five-Year Study from Houston Methodist Confirms LACC Findings

A five-year follow-up study published in the Journal of Clinical Oncology by Houston Methodist Hospital researchers further confirmed that:

• Open radical hysterectomy leads to better disease-free survival and overall survival rates.
• Minimally invasive patients were 4x more likely to relapse and 3x more likely to die from cervical cancer.
• Survival rates:
  • Open surgery: 96.2% overall survival, 96% disease-free survival
  • Minimally invasive surgery: 90.6% overall survival, 85% disease-free survival

Key Takeaways from Houston Methodist Study:

• Minimally invasive radical hysterectomy should no longer be standard practice for early-stage cervical cancer.
• The risks of minimally invasive techniques outweigh their benefits when treating cervical cancer.
• More research is needed to determine if certain modifications to robotic or laparoscopic techniques could improve outcomes.

Dr. Pedro T. Ramirez, the study’s lead researcher, emphasized:

"Minimally invasive procedures have great benefits in reducing complications and improving recovery times, but for cervical cancer, the long-term outcomes are clearly inferior to open surgery."

For now, cervical cancer patients should only undergo minimally invasive radical hysterectomy if participating in an IRB-monitored clinical trial.
