This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a smarter approach to radiation therapy for people with head and neck cancer that has spread to lymph nodes on one side of the neck. Instead of routinely treating both sides of the neck with radiation, doctors will use a special scan (called sentinel lymph node mapping) to see exactly where cancer might spread. This helps them give radiation only to the areas that need it, reducing harm to healthy tissue.
Currently, doctors treat both sides of the neck with radiation to prevent cancer from spreading, even though only some patients actually need it. This approach doubles the amount of radiation exposure and causes more side effects. This trial tests whether using lymph node mapping can safely reduce radiation to only the areas that truly need it, while preventing cancer from returning.

If you join this trial, you will first have a special imaging scan (called SPECT/CT) that uses a radioactive tracer to map where your lymph nodes drain. Based on the results, you may be assigned to one of three treatment groups. Some patients will receive radiation to only the side with cancer; others will be randomly assigned to receive radiation to either the entire lymph node level containing drainage or only the specific draining lymph nodes. Your radiation therapy will use a lower dose than is standard, potentially reducing long-term side effects. You will be followed closely throughout your treatment and afterward to monitor your health.
