From symptom to diagnosis
An abnormal smear test or symptoms? The next step is further investigation, including a biopsy and tissue analysis if needed . If cervical or vaginal cancer is diagnosed, additional tests follow to answer two questions: how far has the tumour spread, and are there any metastases?
The approach to further evaluating cervical and vaginal cancer is largely similar. An MRI scan provides information about the size of the tumour and how far it has grown into surrounding tissue or organs. CT or PET-CT scans check whether there are metastases in the lymph nodes or elsewhere in the body. This information is important for choosing and planning treatment.
For vaginal cancer, additional examination under anaesthesia may sometimes be needed to map out the exact extent of the tumour within the vagina.
When to operate, and when not to
“The approach to treating cervical cancer has become considerably more complex in recent years,” says Dr Salihi. “Which treatment is most suitable depends mainly on how advanced the tumour is, the patient’s general health, and whether she wishes to have children in the future. Put very simply: for early-stage cervical cancer, up to tumours of around 4 centimetres[3], we usually opt for surgery. For the smallest tumours, conisation is often enough. For tumours that can no longer be treated with conisation, a hysterectomy is needed (see below ). That procedure is usually combined with a sentinel node procedure to check whether cancer cells are present in the lymph nodes. For women who wish to have children, there are also alternatives, such as a trachelectomy, in which the cervix is removed but the uterus is preserved, so that pregnancy is still possible later.”
For larger or locally more advanced tumours[4], the standard treatment is chemoradiotherapy (a combination of chemotherapy and radiotherapy, in which the chemotherapy enhances the effect of the radiation), followed by brachytherapy – a form of internal radiotherapy. “If the pelvis needs to be irradiated, the ovaries are usually permanently damaged,” he says. “That’s why, with young women, we always discuss the option of freezing eggs or ovarian tissue. Sometimes we can move the ovaries outside the radiation field. The uterus, however, is usually rendered unsuitable for pregnancy by the radiation.”
Once the disease has spread, surgery is no longer an option. At that point, treating only locally has little benefit, and you need to switch to systemic treatments: treatments that act throughout the entire body. Because, unlike certain forms of breast cancer, cervical cancer is not hormone-sensitive, this treatment usually consists of chemotherapy, sometimes combined with immunotherapy or an angiogenesis inhibitor, a drug that slows the formation of new blood vessels feeding the tumour.
For vaginal cancer, the approach is largely determined by the location of the tumour, Dr Salihi explains. “Broadly speaking: if the tumour is close to the outside, treatment often resembles that for vulvar cancer. If it sits deeper in the vagina, the approach looks more like that for cervical cancer. Surgery is used less often, although small tumours high in the vagina can sometimes still be operated on. In practice, most patients receive chemoradiotherapy followed by brachytherapy. As with cervical cancer, this internal radiotherapy is crucial for gaining local control of the tumour.”
Early diagnosis, good prognosis
The final treatment decision is always discussed within a multidisciplinary team and tailored to the individual patient’s situation. In this context, Dr Salihi wants to correct a common misconception. “Patients think their prognosis is worse if they receive chemoradiotherapy instead of surgery. That’s not true. Chemoradiotherapy, often combined with brachytherapy, is a highly effective treatment for cervical cancer and offers just as good a chance of cure as surgery.”
“Even with locally advanced tumours, for example when the cancer has grown into the tissue around the cervix or into neighbouring organs, we can achieve excellent results with chemoradiotherapy. So, the choice between surgery and chemoradiotherapy isn’t primarily determined by the chance of cure, but by the question of which treatment offers the best balance between effectiveness and side effects in a given situation. If a tumour cannot be fully removed surgically, there’s little point in operating first and then still needing radiotherapy afterwards. In that case, we often choose chemoradiotherapy from the start.”
The most important factor determining prognosis is the stage at which the cancer is detected. If the disease is found at an early stage, the chances of cure (five-year survival) are often above 90%. With metastatic disease, however, the picture looks very different: five-year survival then drops to below 20%.
“That’s why early detection matters so much,” Dr Salihi stresses. “The problem is that cervical and vaginal cancer often cause no, few, or only vague symptoms. As a result, 60 to 70% of cases are only detected at a more advanced stage.”
The focus is shifting from surviving to living
Early menopause, sexual problems, fertility questions, or relationship difficulties – topics that have often received too little attention in the past. The message seemed to be: we’ve cured you, madam, you should be satisfied. But of course, it’s not that simple. Even once the cancer is gone, people can still struggle with the effects of treatment for years afterwards.
Dr Salihi remembers a patient who came in for a consultation years after being treated for cervical cancer. “She was around forty and had pretty much every menopausal symptom you can imagine. Her relationship was struggling, her sex life was non-existent, and psychologically she was in a bad place. She spent an hour telling me about everything that was going wrong.” He suggested trying hormone therapy. “Simply to bring her out of that early menopause. When she came back for a follow-up consultation sometime later, she said: doctor, you’ve cured me. I’ll never forget that. That woman had rediscovered her zest for life. Not because her cancer was gone – it had been gone for years already – but because she finally had her life back.”
These days, doctors take the long-term effects and side effects of treatment into account more than they used to. Even so, according to Dr Salihi, the impact of a gynaecological cancer on relationships and sexuality is still often underestimated. After surgery, sensation in and around the vagina can change, and radiotherapy can make the vagina drier, narrower and less elastic. Research shows that even after a relatively minor procedure, such as a conisation, some women experience difficulties with sexuality. “Not so much because of the procedure itself, but because something has happened to a deeply intimate part of their body,” he says. “I’ve seen women who were still completely preoccupied with what had happened, while their partner didn’t see the problem – the doctor helped you, right? That can put real strain on a relationship.”
Recovery isn’t only physical, but also has an emotional and psychological dimension. That’s why he finds it important for partners to be involved, both during diagnosis and treatment and in aftercare. When they understand what the other person is going through, it becomes easier to face it together. “And that’s also why I strongly believe in multidisciplinary care. Oncology nurses, sexologists, menopause counsellors and other care providers can all help patients with issues that often reach far beyond the cancer itself.”
Early detection, combined expertise
Cervical cancer is one of the most preventable and treatable forms of cancer. Dr Salihi stresses that we need to keep investing in prevention and early detection. “There will probably never be a separate population-wide screening programme for vaginal cancer, the way we have for breast, bowel or cervical cancer. But a thorough examination of the vagina, and of the vulva for that matter, can easily be incorporated into existing cervical screening.”
The classic smear test, however, remains a barrier for too many women. Self-sampling tests could therefore be an important step forward. Still, in his view, self-sampling tests alone won’t solve the problem. “The women who participate least in screening today are often also the hardest to reach through other channels. I think that’s one of the biggest challenges for the coming years.”
On top of that, we need to keep working on further centralising care. “Thanks to vaccination and screening, cervical cancer and other HPV-related gynaecological cancers will become increasingly rare,” he explains. “That’s obviously a good thing, but it also means we will absolutely need to concentrate treatment of these cancers in centres that treat enough patients to maintain that expertise. These don’t necessarily have to be university centres, but they do need to have sufficient experience. Centralisation, by the way, isn’t only about treatment. It’s also about diagnosis – I’m thinking here of the tissue analysis that’s essential for an accurate diagnosis. That requires the expertise of experienced gynaecological pathologists, because some tumours can be difficult to distinguish from one another in a biopsy sample. Centralisation also makes it easier to surround patients with a multidisciplinary team of specialised care providers. In a hospital that only treats one or two patients a year, it’s hard to build up that kind of support structure. In specialised centres, that’s far more achievable.”
“We have the knowledge, the tests and the treatments. We’ll make the biggest gains if we also reach the groups who still too often fall through the cracks today, and if we can offer them good multidisciplinary support in specialised centres,” he concludes.
