Vaginal Cancer: Prognosis, Life Expectancy, and Key Survival Factors for Gynecological Specialists

The vaginal cancer is a rare gynecological neoplasm, which has limited the conduct of phase III clinical trials and has led current guidelines to be primarily based on retrospective studies. Despite its low incidence, it is crucial for specialists to understand the prognostic factors and available treatment options to improve the survival of affected patients.

Diving into Prognosis and Treatment

The prognosis of vaginal cancer is influenced by several factors, notably the stage of the disease and the presence of metastasis in the lymph nodes. A recent study found that positivity for human papillomavirus (HPV) and p16 expression are associated with a better prognosis, while stage III/IV and lymph node metastasis are significant negative predictors of cancer-specific survival [1].

Regarding treatment, options vary according to the stage of cancer. For early stages, surgery and/or radiation therapy are the main therapeutic strategies. In more advanced stages, a combination of external radiation and brachytherapy is commonly adopted, and in selected cases, pelvic exenteration may be considered [2]. Additionally, adjuvant chemotherapy has proven effective in reducing vaginal recurrence and pelvic and para-aortic lymph node involvement [3].

Conclusions

The management of vaginal cancer requires a multidisciplinary and personalized approach, taking into account the individual prognostic factors of each patient. Identifying markers such as HPV and p16 positivity can guide therapeutic decisions and improve the life expectancy of patients. Despite the challenges posed by its low incidence, advances in treatment and understanding of prognostic factors continue to enhance outcomes for patients with this disease [4].
