MINIMALLY INVASIVE SURGERY FOR GYNECOLOGIC CANCERS: THE VALUE OF VIRTUAL SECOND OPINIONS

Medically Reviewed by Dr. Julio Álvarez Bernardi and Dr. José Rubio Valtueña

A Remote Second Opinion (RSO) is a medical consultation provided by a specialist who reviews a patient's case remotely, typically using digital platforms, without the need for an in-person visit. RSOs are an invaluable resource in oncology, providing patients with access to expert opinions that might not be readily available in their local healthcare settings.

In oncology and surgery, RSOs offer patients a chance to receive an additional expert evaluation of their diagnosis, proposed treatment options, and surgical plans. Patients can send detailed medical records, including imaging scans, biopsy reports, and pathology findings, to a remote specialist who evaluates these documents and provides a comprehensive second opinion. This process not only reassures patients but can also influence treatment decisions, particularly in complex cases like gynecological cancers, where treatment options, including surgery, vary widely in approach and effectiveness.

Cancer treatment is often multi-faceted and personalized. Receiving a second opinion is vital because it helps confirm the accuracy of the diagnosis, the appropriateness of the treatment plan, and the proposed surgical approach. Inaccurate or suboptimal diagnoses can lead to ineffective treatment, while unnecessary procedures can add risk and delay recovery. Second opinions, particularly in cases of gynecological cancers, provide patients with the confidence to proceed with a treatment plan that is fully tailored to their individual circumstances, potentially improving outcomes and patient satisfaction.

Telemedicine has become an essential tool in oncology, particularly as technology and digital health solutions have expanded. Virtual consultations enable patients to access specialists from leading cancer centers worldwide, ensuring they can obtain the best possible treatment recommendations. This trend is especially important in specialized fields like gynecologic oncology surgery, where expertise and experience in minimally invasive surgery (MIS) can significantly influence outcomes.

Overview of Minimally Invasive Surgery (MIS) for Gynecologic Cancers

Minimally invasive surgery has transformed the treatment of gynecological cancers. These techniques reduce the trauma associated with traditional open surgery, promoting faster recovery, less postoperative pain, and improved aesthetic outcomes. MIS techniques such as laparoscopy, robotic surgery, and natural orifice transluminal endoscopic surgery (NOTES) are increasingly used for conditions like endometrial, cervical, ovarian, and vaginal cancers, improving the precision and success rates of procedures.

Recent Advances in MIS for Gynecologic Cancers

Several recent advances have expanded the potential of MIS in gynecologic oncology:

Robotic-Assisted Surgery

Robotic-assisted surgery, particularly with systems like the da Vinci Surgical System, enhances surgeon dexterity and precision in gynecologic oncology procedures. It has demonstrated benefits such as reduced blood loss, fewer complications, and shorter hospital stays. Studies indicate that robotic-assisted procedures can improve oncological outcomes for endometrial and cervical cancers while offering comparable survival rates to open surgery.

Hybrid-Actuation Robotic Systems

Hybrid-actuation robotic systems combine robotic precision with human control, offering improved adaptability and real-time adjustments during surgery. Emerging research in micro/nanorobotics has explored various actuation techniques, including magnetic, electric, acoustic, light-based, chemical, and biological mechanisms, aiming to refine the precision and responsiveness of these systems. These technologies are under active development, with ongoing research and preclinical evaluations focusing on enhancing targeted surgical interventions, improving tissue interaction, and minimizing invasiveness. Integrating such advanced actuation methods holds the potential to revolutionize minimally invasive surgical techniques, making procedures safer and more effective in specialized fields like gynecologic oncology.

Laparoendoscopic Single-Site Surgery (LESS)

LESS is a surgical approach that minimizes scarring and accelerates postoperative recovery by utilizing a single incision, typically at the umbilicus. It has been applied successfully in gynecologic oncology for procedures such as hysterectomy and lymphadenectomy. Research highlights its feasibility, safety, and comparable oncological outcomes to multi-port laparoscopic surgery, though hernia risks remain a concern.

Robotic-Assisted LESS

Combining robotic technology with LESS offers enhanced visualization and instrument control while maintaining the advantages of single-incision surgery. It has been explored as a feasible option in gynecologic oncology, particularly for endometrial cancer surgery, and may reduce operator fatigue and improve precision.

Single-Site Robotic Surgery (SSRS)

SSRS merges the advantages of robotic-assisted surgery with a single-site approach to minimize scarring and recovery time. Studies suggest SSRS may be particularly beneficial for endometrial and early-stage ovarian cancer surgeries, providing comparable oncologic safety to multi-port robotic procedures.

Natural Orifice Transluminal Endoscopic Surgery (NOTES, vNOTES)

NOTES and its vaginal variant, vNOTES, allow surgical access to pelvic organs through natural orifices, eliminating the need for external incisions. This approach has been successfully implemented in gynecologic oncology, demonstrating reduced postoperative pain, lower complication rates, and faster recovery compared to traditional laparoscopy.

Fluorescence Image-Guided Surgery

This emerging technology uses special dyes and imaging techniques to enhance tumor and lymph node visualization during surgery. In gynecologic oncology, fluorescence-guided imaging has been shown to improve lymph node mapping and resection accuracy, leading to better staging and potential survival benefits.

When Should Patients Prioritize an RSO to Explore MIS for Gynecologic Cancer?

Several scenarios warrant seeking a remote second opinion to explore MIS options:

• When They Have Been Recommended Open Surgery But Want to Explore Minimally Invasive Options: Not all gynecological cancers require radical surgery. Some patients may be initially advised to undergo open surgery, but MIS may still be a viable option, depending on the stage and location of the cancer. RSOs can help patients verify if conservative surgery is feasible.
• If They Have Been Told MIS Is Not Possible But Want a Second Look: Patients who have been told that MIS is not an option due to the complexity of their case may benefit from a second opinion to explore other possibilities or alternative approaches that could make MIS feasible.
• If Their Doctor Does Not Specialize in MIS and They Want a Second Opinion from a High-Volume Center: Access to a high-volume cancer center through RSOs can connect patients with specialists who perform a greater number of surgeries, providing expert recommendations based on advanced techniques and innovations in gynecological cancer treatment.
• If They Are Exploring Fertility-Preserving Surgery and Need Input from a Specialist in Reproductive Oncology: For patients concerned about preserving fertility, an RSO can connect them with specialists in reproductive oncology, ensuring that the treatment plan includes all available fertility-preserving options.

Benefits of Minimally Invasive Surgery (MIS) Confirmed via RSO

Enhanced Patient Recovery and Quality of Life

• Faster recovery time, enabling patients to return to their daily activities sooner.
• Less postoperative pain and smaller scars compared to traditional surgery.
• Shorter hospital stays, reducing the risk of hospital-associated complications.

Lower Complication Rates Compared to Open Surgery

• MIS techniques carry a lower risk of infection and blood loss.
• Reduced chances of complications such as adhesions, which are more common with open surgery.
• Fewer incidences of long-term issues like bowel dysfunction.

Improved Fertility Preservation Options

MIS techniques enable fertility-preserving procedures, such as trachelectomies or partial ovarian resections, which are vital for younger patients seeking to maintain fertility while undergoing cancer treatment.

Gynecologic Cancers That May Benefit From RSOs for MIS

Endometrial (Uterine) Cancer

Minimally invasive surgery (MIS), including laparoscopic and robotic-assisted hysterectomy, is the standard approach for early-stage endometrial cancer. Studies indicate that MIS leads to lower postoperative morbidity, shorter hospital stays, and quicker recovery compared to open surgery while maintaining oncologic outcomes. The necessity for lymph node dissection can be assessed using sentinel lymph node mapping, reducing the risks associated with full lymphadenectomy. Additionally, in select cases of young women with early-stage disease, fertility-preserving strategies such as hormone therapy combined with hysteroscopic resection can be considered.

Cervical Cancer (Early-Stage Cases)

Minimally invasive radical hysterectomy and trachelectomy (fertility-preserving removal of the cervix) are options for early-stage cervical cancer. However, the LACC trial - a study comparing the oncologic outcomes of minimally invasive versus open radical hysterectomy for early-stage cervical cancer - found that minimally invasive radical hysterectomy was associated with a higher recurrence rate and lower overall survival compared to open surgery. As a result, open surgery is now recommended as the preferred approach for many patients, though MIS is still considered in select cases. Robotic-assisted surgery is being investigated as a way to mitigate the risks observed in the LACC trial while maintaining the benefits of MIS.

Ovarian Cancer (Selected Cases)

Laparoscopic staging surgery is increasingly used for early-stage ovarian cancer, particularly in low-risk cases. Research suggests that MIS provides comparable survival outcomes to open surgery while reducing surgical complications and hospital stays. In patients with recurrent ovarian cancer, robotic-assisted approaches are being explored for secondary cytoreductive surgery. Additionally, MIS techniques can aid in evaluating borderline ovarian tumors and in delivering hyperthermic intraperitoneal chemotherapy (HIPEC), a novel adjunctive treatment.

Vaginal & Vulvar Cancers (Selected Cases)

For early-stage vaginal cancer, minimally invasive radical hysterectomy may be performed, although treatment primarily depends on tumor location and size. In vulvar cancer, sentinel lymph node biopsy (SLNB) has replaced full lymphadenectomy in select cases, significantly reducing morbidity such as lymphedema without compromising oncologic outcomes. Laparoscopic and robotic-assisted techniques have made these procedures more accessible and less invasive, improving patient recovery.

Gynecologic Cancers Where RSOs for MIS May Be Less Relevant

• Advanced-Stage Ovarian Cancer (Stage III-IV): These stages often require open cytoreductive surgery due to the need for extensive debulking, a process that is not feasible with MIS. Debulking is a procedure aimed at removing as much tumor mass as possible, typically performed in advanced ovarian cancer to improve survival outcomes and enhance the effectiveness of chemotherapy.
• Locally Advanced Cervical Cancer (Stage IB2 or Higher): The higher recurrence risk observed in the LACC trial makes open surgery the preferred choice for most high-volume centers in cases of locally advanced cervical cancer.
• Aggressive or Rare Uterine Cancers: Uterine sarcomas and clear cell carcinomas are aggressive subtypes of uterine cancer, with uterine sarcomas arising from the muscle or connective tissue and clear cell carcinomas being a distinct histological type often associated with poorer prognosis and resistance to standard treatments. For such cancers, the risk of peritoneal spread is higher, making open surgery the standard approach to ensure complete resection.

How Remote Second Opinions Work for Gynecologic Cancer Patients

Process for Seeking an RSO

Patients initiate the process by gathering medical records, pathology reports, imaging studies, and treatment summaries. These documents are submitted to a specialist who conducts a thorough review and provides a recommendation, often involving a virtual consultation.

Key Specialists Involved in RSOs for MIS in Gynecologic Oncology

• Gynecologic Oncologists: Specialists who provide in-depth expertise in treating gynecological cancers.
• Minimally Invasive Surgeons: Experts in laparoscopic and robotic surgery techniques.
• Pathologists and Radiologists: Specialists who evaluate tissue samples and imaging studies to help confirm diagnoses and surgical options.

Recent Research in MIS for Gynecologic Cancers

Role of MIS in Advanced Cases

Ongoing research is examining the feasibility of MIS for more advanced cases, with promising results in reducing morbidity and improving recovery times. A study by Pereira et al. explored the potential of MIS for advanced ovarian cancer and found that laparoscopic staging and cytoreduction resulted in fewer complications and significantly shorter hospital stays compared to traditional open surgery. Additionally, a study by Kim et al. focused on advanced uterine cancers and demonstrated that robotic-assisted surgery led to improved recovery times, less blood loss, and a reduced risk of surgical site infections, showcasing the efficacy of MIS in more complex cases. These findings suggest that MIS can offer significant advantages for patients with advanced gynecologic cancers, potentially enhancing both clinical outcomes and quality of life.

Artificial Intelligence (AI) in Gynecologic Oncology

AI is increasingly enhancing various aspects of gynecologic oncology. A review published in the Obstetrical & Gynecological Survey journal reported on the applicability of AI in the diagnosis and treatment of cervical, uterine, and ovarian cancers. In cervical cancer, AI algorithms were shown to improve image analysis for cytology and colposcopy, aiding early detection. For uterine cancers, AI can enhance diagnostic accuracy through advanced imaging techniques and refine prognostic assessments by analyzing disease symptoms and pathology. In ovarian cancer, AI contributed to early-stage detection and assisted in predicting surgical outcomes and treatment responses.

Enhancing Visualization With Augmented Reality (AR)

Augmented reality is emerging as a valuable tool in minimally invasive gynecologic oncology surgeries, enhancing surgical precision and outcomes. A case report detailed the integration of holography and AR during robotic-assisted surgery for endometrial cancer. Sentinel lymph nodes were identified using mixed reality (MR) technology, which visualized a fusion of preoperative imaging and single-photon emission computed tomography (SPECT) and CT scans. This technique allowed the surgical team to gain a clear three-dimensional view of the lymph nodes in relation to nearby critical structures. Additionally, real-time holographic projections during surgery helped with precise lymph node identification and to reduce invasiveness.

Conclusion

In cases of early-stage uterine, cervical, and borderline ovarian cancers, RSOs can play a crucial role in confirming eligibility for MIS, optimizing surgical planning, and improving patient outcomes. However, for advanced-stage or aggressive cancers, open surgery remains the standard approach.

For patients considering MIS for gynecologic cancer or seeking clarity on their treatment plan, obtaining an RSO from a minimally invasive gynecologic oncology expert is an important step in making informed decisions. RSOs can help improve surgical decision-making, mitigate risks, and potentially provide a faster recovery with less invasive procedures.
