Vulvar cancer treatment covers the surgical and non-surgical approaches used to remove or control cancer in vulvar tissue. The plan depends on the stage, tumor size, lymph node involvement, and general health. Most patients begin with surgery. Radiation and chemo may follow or serve as the primary approach when operating is not safe. According to GLOBOCAN 2022 (IARC/WHO), vulvar cancer makes up a small but growing share of gynecological cancers worldwide. Early disease may need a limited procedure, while advanced cases require coordinated planning across specialties.

Key Highlights

Surgery is usually the first step when it comes to treating vulvar cancer
A sentinel lymph node biopsy can check whether the cancer has spread, without having to remove all the lymph nodes
Radiation is pretty flexible in how it's used; it can come before surgery, after it, or even serve as the main treatment on its own
When chemo and radiation are combined, it's called chemoradiation, and it's typically used when the tumor is more locally advanced
If surgery is extensive, reconstructive options are available to help restore the area afterward
For advanced or recurring disease, systemic therapies are usually brought into the picture
Every treatment plan is shaped by a specialist team that looks at pathology results, scans, and what matters most to the patient

What Does Surgery for Vulvar Cancer Look Like?

For most vulvar cancers, surgery is where treatment begins. The type of operation depends on the tumor's size, depth, and position relative to the urethra or anus. Surgeons aim to remove the cancer completely while sparing as much normal tissue as they can.

Wide Local Excision

Think of wide local excision as the least extensive option. The surgeon removes the tumor along with a rim of healthy tissue. It works well for small, early-stage tumors.

What counts as a successful result? The pathologist examines the edges of the removed tissue. If no cancer cells appear at those edges, the margins are “clear,” meaning a lower chance of local recurrence.

Partial or Radical Vulvectomy

When a tumor is larger, a partial vulvectomy removes the involved section while keeping the rest intact. A radical vulvectomy removes the entire vulva along with deeper tissue. Doctors choose radical surgery only when a smaller surgery would risk leaving the disease behind.

Comparing Surgical Approaches

Feature	Wide Local Excision	Partial Vulvectomy	Radical Vulvectomy
Tissue removed	Tumor plus margin	Affected vulvar section	Entire vulva and deeper tissue
Typical use	Small early-stage tumors	Larger localized tumors	Extensive or deeply invasive disease
Recovery timeline	Shorter	Moderate	Longer, reconstruction possible
Function preservation	Usually high	Varies by location	May be limited

How Do Doctors Check the Lymph Nodes?

The inguinofemoral lymph nodes in the groin are usually where vulvar cancer travels first. Surgeons check them during the operation because findings change the rest of the treatment.

One approach is sentinel lymph node biopsy. A tracer identifies the first nodes receiving drainage from the tumor. If those come back clean, removing the remaining groin nodes can often be skipped. Full node removal carries the real risk of lymphedema, persistent leg swelling that can last months or years.

When a sentinel biopsy is not appropriate, surgeons proceed with an inguinofemoral lymphadenectomy.

Does Reconstruction Come Into Play?

After extensive vulvar surgery, reconstructive procedures may be offered. Tissue flap techniques reposition tissue from a nearby area to rebuild the site. Planning usually happens before cancer surgery, so both steps map together.

Not everyone needs or wants reconstruction. The decision depends on the tissue removed and personal preference.

When Is Radiation Therapy Used?

Radiation directs high-energy beams at cancer cells. It enters vulvar cancer treatment at different points.

After surgery, radiation may be recommended if the margins were tight or the nodes are positive. Before surgery, it can shrink a large tumor for a cleaner resection. Some patients receive radiation as primary treatment when the tumor sits too close to the urethra or anus, or when health issues make surgery too risky.

Bottom line: Sessions span several weeks, with each plan customized to the patient’s anatomy.

Quick note: Modern radiation techniques such as intensity-modulated radiation therapy (IMRT) allow more precise targeting, which helps reduce side effects to surrounding healthy tissue.

How Does Chemoradiation Work Differently?

Chemoradiation means giving chemo and radiation at the same time. Certain drugs make cancer cells more vulnerable to radiation, a process called radiosensitization.

Where does it fit? Mainly in locally advanced vulvar cancer, where the tumor has grown into structures that cannot be safely removed. It can also follow surgery when pathology suggests a higher recurrence risk. The oncology team selects drugs based on overall condition and prior treatment history.

Are There Systemic Therapy Options?

Systemic treatments work through the bloodstream rather than targeting one spot. Two categories apply for advanced or recurrent vulvar cancer:

Targeted therapy zeroes in on molecular changes driving certain vulvar tumors
Immunotherapy helps the immune system recognize and fight cancer cells

Whether systemic therapy fits depends on tumor biology, prior treatments, and current overall health. Clinical trials may also be worth discussing with the care team.

How Does Stage Shape the Treatment Plan?

Stage is the single biggest factor when choosing treatment.

Early-stage vulvar cancer, still confined to the vulva, is usually managed with wide local excision plus sentinel node biopsy. Clear margins and negative nodes may mean no additional treatment is needed.

Advanced disease typically calls for surgery combined with radiation or chemoradiation. Which comes first depends on imaging and pathology findings.

Recurrent cancer gets a fresh evaluation based on what was done before and where the disease has returned.

Taking the Next Step

No two vulvar cancer treatment plans look the same. Stage, tumor characteristics, lymph node status, and personal health all feed into the decisions.

When decisions need to be made, HCG helps by centering each plan on an evidence-based, multidisciplinary review. Specialists at HCG Cancer Hospital evaluate cases collaboratively, weighing both what the disease demands and what matters to the patient’s quality of life.

If you or a family member is navigating this diagnosis, a conversation with a gynecologic oncology team can bring clarity:

Why is this particular treatment being recommended?
What does surgery involve, and what should recovery look like?
Will lymph nodes be checked, and how would the results affect next steps?
Should reconstruction be discussed before the operation?
Would a second opinion be appropriate?

Frequently Asked Questions

What are the main vulvar cancer treatment options?

The primary approaches include surgery, radiation, chemoradiation, and systemic therapies such as immunotherapy or targeted drugs. Surgery is the most common first step, with additional treatments guided by stage, lymph node findings, and pathology results.
