Vulvar Cancer Treatment Options
Vulvar cancer is a rare type of cancer that forms on the surface of the outer female genitalia. Treatment plans are highly personalized, based on the cancer’s stage, type, and the patient’s overall health, and understanding the available options can help patients and families work with their care team.
Key Takeaways
- Vulvar cancer treatment usually combines surgery, radiation therapy, and chemotherapy, chosen according to the cancer’s stage and the patient’s overall health.
- Surgery — removing the tumor with a margin of healthy tissue, or part or all of the vulva — is the most common treatment and is usually the starting point for early-stage disease.
- Radiation therapy and chemotherapy are used after surgery to lower the chance of recurrence, before surgery to shrink large tumors, or on their own when an operation is not a safe option.
- Research into targeted therapy and immunotherapy for advanced or recurrent vulvar cancer continues, mainly through clinical trials.
- Managing treatment side effects is an ongoing part of care throughout the treatment journey.
Overview of Vulvar Cancer Treatment Options
The goal of vulvar cancer treatment is to remove the cancer while trying to preserve vulvar structure, function, and the patient’s quality of life. A care team — typically a gynecologic oncologist working alongside radiation and medical oncology specialists — builds a plan around several factors: the cancer’s stage, size, and location; whether it has reached the lymph nodes; and the patient’s general health and preferences.
Surgery, radiation therapy, and chemotherapy are the main treatments used, often in combination, and early-stage cancers may need surgery alone. The National Cancer Institute notes that squamous cell carcinoma accounts for over 90% of invasive vulvar cancer cases, so most treatment guidance is built around managing this histologic type.
Surgical Approaches
Surgery, aimed at removing the tumor, is generally the first and most frequently used treatment for vulvar cancer. How much tissue is removed depends on the tumor’s size and location. A wide local excision takes out the cancer along with a rim of surrounding healthy tissue for smaller lesions. For larger or more invasive tumors, a radical local excision removes a wider margin, or a vulvectomy removes part of the vulva (modified radical vulvectomy) or the entire vulva (radical vulvectomy); nearby groin lymph nodes are frequently removed at the same time.
Lymph node evaluation is a standard part of surgery for all but the smallest tumors, since it shows whether the cancer has spread and guides further treatment. For early-stage disease with a smaller tumor and no sign of groin node involvement on exam, a sentinel lymph node biopsy can be used instead of removing all the groin nodes: only the first node(s) the cancer would likely reach are sampled, and a full groin dissection is reserved for patients whose sentinel node tests positive. When surgery has removed all the visible cancer, some patients still receive radiation and/or chemotherapy afterward — called adjuvant therapy — to destroy any remaining cancer cells and lower the chance the disease returns.
Radiation Therapy
Radiation therapy for vulvar cancer is typically delivered as external beam radiation, using a machine outside the body to aim high-energy rays at the cancer. It is commonly used as adjuvant therapy after surgery, and radiation is also typically included in the treatment plan for stage III or IV vulvar cancer. For tumors that are too large to operate on safely, or for patients who cannot tolerate radical surgery, radiation therapy (often combined with chemotherapy) may be used as the primary treatment, sometimes shrinking a tumor enough beforehand to make surgery possible. External radiation may also be used to ease symptoms and support day-to-day well-being in advanced disease.
Chemotherapy is generally not the primary treatment for early-stage vulvar cancer. It is more often combined with radiation (chemoradiation) — usually before surgery, to shrink a large or locally advanced tumor and make it more operable — or used for advanced, recurrent, or metastatic disease. Because vulvar cancer is rare, its chemotherapy regimens are largely adapted from anal and cervical cancer protocols, typically pairing fluorouracil (5-FU) with cisplatin or mitomycin. There is no single standard chemotherapy regimen for metastatic vulvar cancer, and the supporting evidence is limited.
| Treatment Modality | Primary Use | Key Considerations |
|---|---|---|
| Surgery | First-line treatment for localized cancer; removal of the tumor and, often, groin lymph nodes. | Extent varies (wide local excision to radical vulvectomy); potential for body image changes and lymphedema. |
| Radiation Therapy | Adjuvant after surgery; primary treatment for stage III/IV or inoperable tumors; often combined with chemotherapy. | Delivered as external beam radiation; skin irritation, fatigue, and long-term tissue changes. |
| Chemotherapy | Combined with radiation before surgery for large tumors; for advanced or recurrent disease. | Systemic effects; regimens (e.g., fluorouracil with cisplatin) are adapted from other cancers, and no regimen is considered standard for metastatic disease. |
New and Emerging Treatments for Vulvar Cancer
Beyond surgery, radiation, and chemotherapy, researchers continue to study targeted therapy and immunotherapy approaches for vulvar cancer, particularly for advanced or recurrent disease. One immune-based option already used off-label for precancerous vulvar lesions (vulvar intraepithelial neoplasia) is topical imiquimod, a cream that helps the immune system respond to abnormal cells; its role in treating invasive vulvar cancer itself remains investigational.
For patients with advanced or recurrent disease, clinical trials remain the main way to access newer treatment approaches before they become part of standard care. The National Cancer Institute maintains a list of open clinical trials for vulvar cancer, and a patient’s care team can help determine whether a particular trial fits their situation.
Reasons patients consider joining a clinical trial include:
- Access to treatments not yet available outside of a research study.
- Close monitoring and care from a specialized medical team.
- Contributing to research that may help future patients.
- In many trials, patients who do not receive the experimental treatment still receive the current standard treatment.
Managing Vulvar Cancer Treatment Side Effects
Vulvar cancer treatment side effects vary depending on which therapies a patient receives and how extensive they are. Surgery can cause pain, wound-healing problems, and changes in sensation or body image; when groin lymph nodes are removed, there is an added risk of lymphedema, or chronic swelling of the legs or genital area. Radiation therapy commonly causes skin irritation in the treated area and fatigue, and chemotherapy’s side effects are systemic, similar to those seen with other cancers.
Talking with the care team early, and reporting new or worsening symptoms promptly, allows most side effects to be managed through medication, wound care, physical therapy, or emotional support.

Frequently Asked Questions
How is the best vulvar cancer treatment determined?
A team of specialists, usually led by a gynecologic oncologist, chooses a treatment plan based on the cancer’s stage, size, and location, whether it has reached the lymph nodes, and the patient’s overall health and preferences. The goal is to remove the cancer while preserving as much vulvar function as possible.
What are the long-term impacts of vulvar cancer treatment?
Surgery can permanently change the vulva’s appearance and sensation, and removing groin lymph nodes carries a lasting risk of lymphedema. Radiation therapy can leave long-term skin and tissue changes in the treated area. Massive Bio’s guide to managing vulvar cancer treatment side effects covers these effects in more detail.
Can vulvar cancer recur after treatment?
Yes — vulvar cancer can return locally, in nearby groin lymph nodes, or in distant parts of the body, even after successful initial treatment. Regular follow-up exams help catch a recurrence early, and further surgery, radiation, or systemic therapy can be considered if it happens.
