Stage II Oral Cancer: Is Neck Dissection Necessary After Surgery? - Otolaryngology

In the context of Stage II oral cancer, the decision regarding whether to perform a neck dissection after surgery is multifaceted and should be tailored to the individual patient's circumstances. Your sister's case, where a malignant tumor was identified in the left buccal mucosa and subsequent imaging showed no lymph node involvement, is indeed a critical factor in determining the necessity of neck dissection.

Stage II oral cancer typically indicates that the tumor is larger than 2 cm but not more than 4 cm, and there is no evidence of regional lymph node metastasis (N0) or distant metastasis (M0). In such cases, the standard treatment often involves surgical excision of the primary tumor, which your sister has already undergone. The question of whether to perform a neck dissection is primarily based on the risk of occult metastasis, which refers to cancer cells that may be present in the lymph nodes but are not detectable through imaging studies.

The rationale for performing a neck dissection in Stage II oral cancer is to remove any potentially affected lymph nodes, thereby reducing the risk of recurrence and improving overall survival rates. However, if imaging studies, such as CT scans or MRIs, show no signs of lymph node involvement, some oncologists may opt to forgo neck dissection, especially if the tumor margins are clear and there are no other concerning features in the pathology report.

It is essential to have a thorough discussion with your sister's oncologist regarding the specific characteristics of her tumor, the pathology report, and the potential benefits and risks of neck dissection. Factors such as the tumor's histological grade, depth of invasion, and the presence of perineural or vascular invasion can influence the decision. If the oncologist believes that the risk of metastasis is low, they may decide that neck dissection is not necessary.

Regarding the possibility of performing a neck dissection after your sister has already undergone surgery, it is generally feasible to conduct additional surgeries, but this depends on her recovery and overall health status. If there is a clinical indication for neck dissection, the surgical team will evaluate her condition and determine the appropriate timing for any further procedures.

In summary, while neck dissection can be an important component of treatment for Stage II oral cancer, its necessity is not absolute and should be based on individual patient factors. It is crucial to maintain open communication with the healthcare team to ensure that your sister receives the most appropriate care tailored to her specific situation.
