HPV-independent vulvar squamous cell carcinoma: the decisions you may face

5 treatment settings, 3 with more than one named option. Each section lays out the options the standard of care names, what each is for, the trials behind them with their recorded results, the side effects and cautions on record, and questions to ask. Built from the cancer page's standard-of-care rows; nothing here is advice for your case.

Other settings

Precursor (differentiated VIN) and lichen sclerosus

One path named

Excision of differentiated VIN; long-term potent topical corticosteroids for lichen sclerosus; low threshold for biopsy of new lesions.

The path, in plain words

Destroying precancerous cervical cells with a heated or frozen probe in under a minute, the tool that makes screen-and-treat possible where there are no surgeons.

  • Cheap, fast, no anaesthesia or electricity mains
  • Enables single-visit screen-and-treat
The evidence behind it

No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.

The main trade-offs on record
  • No histology
  • Not suitable for large or endocervical lesions
Questions to ask about this decision
  1. Is Thermal ablation and cryotherapy for cervical precancer the only reasonable path for me, or is there a trial, a different sequence or a wait-and-see option?
    Why: A single standard does not mean a single choice; timing and trials are decisions too.
  2. What is each option trying to achieve: cure, long control, or relief of symptoms, and over what time?
    Why: The aim shapes how much side effect and disruption is worth accepting.
  3. What happens if I delay, or decline this step for now? Is the decision reversible?
    Why: Some decisions can wait for a second opinion or a trial slot; others cannot. Knowing which is part of the choice.
  4. Does your recommendation follow the current guideline (NCCN Guidelines: Vulvar Cancer), and if it departs from it, why?
    Why: Departures from guidelines are sometimes right for an individual; they should be explained.
  5. For my situation (precursor (differentiated vin) and lichen sclerosus), which of the standard options do you recommend and why?
    Why: Guideline options include: Excision of differentiated VIN; long-term potent topical corticosteroids for lichen sclerosus; low threshold for biopsy of new lesions.

2 options

Wide local excision with attention to margins, sentinel node biopsy or inguinofemoral lymphadenectomy by the GROINSS-V criteria; adjuvant radiotherapy for close margins or positive nodes.

The options, in plain words

Removing just the first lymph node a tumour drains to, instead of all of them, to check for spread.

  • Avoids lymphoedema from full dissection

IMRT and IGRT shape the radiation beam to the tumour's outline from multiple angles and check the patient's position with a scan before every session, so surrounding organs receive less dose. Fewer, larger doses are now standard in breast and prostate cancer, but a low-dose bath still spreads across normal tissue.

  • Conformal dose, fewer side effects
  • Hypofractionation saves visits
The evidence behind it

No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.

The main trade-offs on record
  • False negatives in ~5-10%
  • Low-dose bath to normal tissue
  • Motion management
Questions to ask about this decision
  1. Between Sentinel lymph node biopsy and IMRT / IGRT (modern external beam), which do you recommend for me, and what about my case would make you choose differently?
    Why: Guidelines list several reasonable options; the choice turns on details of your tumour, your health and your priorities.
  2. What is each option trying to achieve: cure, long control, or relief of symptoms, and over what time?
    Why: The aim shapes how much side effect and disruption is worth accepting.
  3. What happens if I delay, or decline this step for now? Is the decision reversible?
    Why: Some decisions can wait for a second opinion or a trial slot; others cannot. Knowing which is part of the choice.
  4. Does your recommendation follow the current guideline (NCCN Guidelines: Vulvar Cancer), and if it departs from it, why?
    Why: Departures from guidelines are sometimes right for an individual; they should be explained.
  5. For my situation (early stage), which of the standard options do you recommend and why?
    Why: Guideline options include: Wide local excision with attention to margins, sentinel node biopsy or inguinofemoral lymphadenectomy by the GROINSS-V criteria; adjuvant radiotherapy for close margins or positive nodes.

Locally advanced

Locally advanced disease

2 options

Cisplatin chemoradiotherapy with surgery for residual disease; responses are less complete than in p16-positive tumours.

The options, in plain words

Cisplatin is the original platinum chemotherapy, discovered by accident in 1965; it cures testicular cancer and makes radiation work better in cervical and head and neck cancer.

IMRT and IGRT shape the radiation beam to the tumour's outline from multiple angles and check the patient's position with a scan before every session, so surrounding organs receive less dose. Fewer, larger doses are now standard in breast and prostate cancer, but a low-dose bath still spreads across normal tissue.

  • Conformal dose, fewer side effects
  • Hypofractionation saves visits
The evidence behind it

No trial record is attached to this row yet. The trials tab lists what is recruiting and the landmark trials for this cancer.

The main trade-offs on record
  • Dose reduce or avoid for CrCl below 60 (carboplatin is the alternative).
  • Low-dose bath to normal tissue
  • Motion management
Questions to ask about this decision

    Why: Guideline options include: Cisplatin chemoradiotherapy with surgery for residual disease; responses are less complete than in p16-positive tumours.
  6. Am I a candidate for Cisplatin, and what side effects should I expect?
    Why: Knowing the expected toxicities helps you plan work, family, and supportive care.

Advanced, first line

Recurrent or metastatic disease

Carboplatin and paclitaxel with or without bevacizumab; pembrolizumab for PD-L1-positive tumours; trials of pembrolizumab with lenvatinib and of cadonilimab.

The options, in plain words

Carboplatin is a platinum chemotherapy that crosslinks DNA; it is part of the standard pre-surgery regimen for triple-negative breast cancer.

A microtubule poison discovered in the Pacific yew tree, among the most used chemotherapies in breast, lung, and ovarian cancer.

Bevacizumab is a humanised antibody that soaks up VEGF-A, the signal tumours use to grow new blood vessels. Approved in 2004, it partners chemotherapy in colorectal, ovarian, cervical, lung, kidney and liver cancer and glioblastoma, and adds to trifluridine/tipiracil in late-line bowel cancer; hypertension, protein in the urine and bleeding are its characteristic side effects.

Pembrolizumab is a PD-1 blocking antibody approved in more than 40 settings, from melanoma and lung cancer to the first tumour-agnostic approval for mismatch-repair-deficient tumours in 2017, and before and after surgery in triple-negative breast cancer. A subcutaneous form arrived in 2025, and it is the backbone partner for ADCs and personalised neoantigen vaccines.

How to read this page. Options and results come from OnCo records with their sources; the settings are the standard-of-care rows on the cancer page, and the lines of therapy are on the sequencing grid. Where a setting names one path, the choice is usually about timing, trials and where to be treated: see expert centres. OnCo is orientation, not medical advice.
