Complications of Vulvar Cancer Surgery

Introduction:

Vulvar cancer, while relatively rare, presents significant challenges to those affected by it. Surgery remains a primary treatment option for vulvar cancer, aiming not only to remove the cancerous tissue but also to preserve functionality and maintain quality of life. However, like any surgical procedure, vulvar cancer surgery comes with its own set of complications and risk factors, which necessitate careful consideration, discussion, and management by both patients and doctors.

What Is Vulvar Cancer Surgery?

Vulvar cancer surgery involves the removal of cancerous tissue from the external female genitalia. Depending on the stage and extent of the cancer, surgical interventions can range from less invasive procedures, such as a wide local excision, to more radical approaches, like a vulvectomy, which involves removing part or all of the vulva.

What Are the Risk Factors for Vulvar Cancer Surgery?

Risk factors for vulvar cancer surgery can depend on various factors, including the patient, site of cancer, involvement of lymph nodes, and surgical expertise. Some common risk factors are:

• Older patients might have additional health concerns or reduced physiological reserves, increasing the risks associated with surgery and anesthesia.

• Medical comorbidities like increased blood pressure dysregulations in the blood glucose and cholesterol levels can put the individual at extreme susceptibility to potential complications.

• Tobacco use impairs circulation and decreases the body's ability to heal, thereby increasing the risk of adverse effects like prolonged wound healing and recurrent infections.

• More extensive surgeries might be required for advanced-stage vulvar cancers, leading to a higher likelihood of complications. Larger tumors or those located in challenging anatomical areas might necessitate more complex surgeries, increasing the risks associated with the procedure.

• When cancer spreads to nearby lymph nodes, the surgical removal of these nodes can lead to complications such as lymphedema and affect immune function.

• Radical vulvectomy or more extensive procedures involving the removal of a significant portion of the vulva and adjacent tissues pose higher risks than less invasive surgeries like local excision. Surgeon experience and skill significantly impact surgical outcomes. Surgeons experienced in vulvar cancer surgeries may reduce the risk of complications.

How Is Vulvar Cancer Surgery Done?

Vulvar cancer surgery involves the removal of cancerous tissue from the external female genitalia, aiming to eradicate the cancer while preserving function and appearance whenever possible. Less invasive procedures like wide local excision involve excising the tumor along with a portion of surrounding healthy tissue. For more extensive cancers, radical procedures such as partial or total vulvectomy may be necessary, which involve removing a portion or the entirety of the vulva. Lymph nodes in the groin area may also be extracted or sampled to assess the spread of cancer. Surgeons often employ meticulous techniques to spare healthy tissue, maintain functionality, and reconstruct the vulva if needed. The goal of vulvar cancer surgery is to achieve complete cancer removal while minimizing physical and psychological impact on the patient's quality of life.

What Are the Complications of Vulvar Cancer Surgery?

• Postoperative bleeding or infection at the surgical site can occur, requiring medical attention and possible interventions to control bleeding or administer antibiotics. This is the most common complication and requires immediate medical interventions to avoid further tissue damage.

• Complications such as delayed wound healing, wound breakdown, or formation of wound abscesses might arise, particularly in cases of extensive tissue removal or in patients with conditions like diabetes or poor circulation.

• Excising lymph nodes from the groin region can result in the onset of lymphedema, causing swelling and fluid retention in the legs, potentially impacting mobility and requiring ongoing management.

• Surgical procedures involving the pelvic region might cause urinary difficulties or bowel function changes, such as urinary retention or constipation, requiring intervention or management strategies.

• Surgery involving the genital area can lead to altered sensation, pain during intercourse, or changes in sexual function, impacting intimacy and necessitating supportive care and potential interventions.

• Coping with changes in body image, function, and the diagnosis of cancer can lead to psychological distress, anxiety, or depression, requiring support and counseling.

• Rare but possible complications include nerve damage, blood clots, or complications related to anesthesia.

How to Manage Risk Factors and Complications of Vulvar Cancer Surgery?

• Thorough assessments, including radiographic assessment, histopathological reviews, and biopsies, aid in understanding the extent and nature of the cancer, enabling surgeons to plan the most appropriate surgical approach. Proper planning can reduce the complications to a greater extent.

• Surgeons may employ minimally invasive approaches whenever feasible to reduce trauma, enhance recovery, and minimize complications. Skillful surgical techniques, including precise tissue removal and preservation of healthy tissue, aim to minimize complications and optimize postoperative outcomes.

• Continuous monitoring of the surgical site, fluid resuscitation, and immediate management of any infection should be done to reduce further extent of damage to surrounding tissues and the body.

• After the surgery is completed, it is paramount to undergo a rehabilitative phase. This phase can include therapies that focus on the physical development of the body and help restore the emotional balance of an individual, as the process of going through a cancer surgery can be mentally draining. Failure to restore the balanced body and mind can further exacerbate the incidence of depression, stress, and anxiety.

How to Improve the Prognosis After Vulvar Cancer Surgery?

Advancements in surgical techniques, such as nerve-sparing procedures, sentinel lymph node mapping, and reconstructive surgery, have aimed to minimize complications and preserve function. Additionally, a multidisciplinary approach involving gynecologic oncologists, surgeons, oncology nurses, physical therapists, and mental health professionals helps address the diverse needs of patients undergoing vulvar cancer surgery. Continued research into novel surgical techniques, adjuvant therapies, and personalized treatment approaches is essential for improving surgical outcomes and minimizing complications. Clinical trials and advancements in targeted therapies offer hope for more effective and less invasive treatment options.

Conclusion:

Vulvar cancer surgery, while essential for treating the disease, poses inherent risks and potential complications. However, through careful preoperative evaluation, meticulous surgical techniques, and comprehensive postoperative care, healthcare providers aim to minimize these risks and enhance patient outcomes. Moreover, a patient-centered approach, coupled with ongoing research and innovation, holds promise for continually improving surgical outcomes and the overall quality of life for individuals undergoing vulvar cancer surgery.
