Vaginal squamous cell carcinoma is the commonest form of vaginal cancer, caused by the same HPV infection as cervical cancer and often following earlier cervical disease. It is treated much as cervical cancer is, with radiotherapy, brachytherapy and cisplatin for most stages and surgery only for small upper-vaginal tumours, and it is prevented by HPV vaccination and cervical screening.
Squamous cell carcinoma makes up most primary vaginal cancers and shares its cause and precursor with cervical cancer: persistent high-risk HPV infection leading to vaginal intraepithelial neoplasia (VAIN), which is commonest at the vaginal vault after hysterectomy for cervical precancer. The strict definition excludes tumours that reach the cervix or vulva, which are classified as cervical or vulvar, and metastases from the cervix, endometrium and bowel outnumber true primaries. Diagnosis is by biopsy at colposcopy, staging is clinical and by MRI and PET-CT under the FIGO system shared with cervical cancer, and p16 confirms HPV association.
Because the disease is rare, no randomised trial has ever been run in it, and treatment is extrapolated from cervical cancer. High-grade VAIN is treated with laser ablation, excision, topical imiquimod or fluorouracil, or brachytherapy for extensive vault disease. Small stage I tumours of the upper vagina can be removed by radical upper vaginectomy with pelvic lymphadenectomy, but most patients receive external beam radiotherapy to the pelvis and groins followed by brachytherapy, with concurrent weekly cisplatin for stage II and above by analogy with cervical chemoradiotherapy; brachytherapy dose is the strongest determinant of local control. Recurrent or metastatic disease is treated as cervical cancer, with carboplatin and paclitaxel with or without bevacizumab and with pembrolizumab for PD-L1-positive tumours, extrapolating KEYNOTE-826. HPV vaccination and cervical screening prevent the disease, and Chinese vaccine trials list vaginal cancer among their endpoints.
The large majority of primary vaginal cancers, mostly in women over 60, many with a history of cervical precancer or hysterectomy for it; a tumour is called vaginal only when the cervix and vulva are uninvolved.
Most high-grade ovarian cancers begin at the tip of the fallopian tube; endometrial cancer lines the uterus, cervical cancer starts at the transformation zone; each drains to a different node group.

The treatment pathway on the vaginal cancer pages, radiotherapy with brachytherapy and cisplatin sensitisation for locally advanced disease, follows this report.
Because primary vaginal cancer is too rare for randomised trials, staging and prognosis rest on registry reports like this one, and treatment is extrapolated from cervical cancer.

One section per setting: the options named, what each is for, the trials behind them, the recorded trade-offs and the questions to ask.
Bleeding that does not stop by itself, bleeding from more than one site, or new bruising in several places or one large area.
Persistent headache with extreme tiredness, nausea, dizziness on standing or low blood pressure. Vomiting, severe weakness or collapse is adrenal crisis.
Capecitabine: take within 30 minutes after a meal. DPD deficiency (DPYD variants) causes severe toxicity: pre-treatment genotyping is recommended in Europe.
