For stage I/II vaginal squamous cell carcinoma, what is the recommended treatment for tumors less than 2 cm in size?

In the case of stage I/II vaginal squamous cell carcinoma for tumors that are less than 2 cm in size, the recommended treatment is surgical excision. This approach is based on the early-stage classification of the tumor, where the disease is localized and typically presents with a good prognosis.

Surgical excision involves the complete removal of the tumor, which not only provides a definitive diagnosis through histopathological examination but also aims to ensure clear margins, reducing the likelihood of recurrence. For tumors of this size, radical surgical options are often not necessary, and less extensive procedures can be effectively performed, depending on the extent of the disease.

Other treatment modalities, such as chemotherapy or radiation therapy, are generally reserved for larger tumors, advanced stages, or for certain cases where surgical intervention may not be feasible. For instance, radiation therapy might be considered in cases where the tumor is larger or there are specific clinical indications for non-surgical management. However, for small, early-stage tumors, excision remains the preferred treatment method.
