Early Oral Cavity Cancer Timeline: Surgery Followed by Radiation

When the pathology report after surgery for an early mouth cancer shows higher-risk features, about 6 weeks of radiation is often added, ideally starting within 6 weeks of the operation.

 

This page is one of three treatment-track timelines for early oral cavity cancer. The steps before treatment, how a track is chosen and the follow-up schedule are covered on the early oral cavity cancer treatment timelines page.

Who follows this track

Everyone on this track starts with the same surgery as on the surgery alone track. Radiation is added when the pathology report shows features that raise the chance of the cancer returning, such as:

  • a tumor that turned out deeper or larger than expected (upstaged to pT3 or pT4);

  • cancer in more than one lymph node, or in lymph nodes low in the neck;

  • cancer tracking along nerves (perineural invasion) or within small vessels (lymphovascular invasion);

  • close margins.

When a single small lymph node is the only finding, radiation may be considered rather than required.

Before surgery and surgery (weeks 0 to 4)

The biopsy, scans, team visits and tumor board are described on the overview page, and the operation on the surgery alone page: tumor removal through the mouth with a neck dissection or sentinel lymph node biopsy, and a hospital stay often of 1 to 3 days.

Between surgery and radiation (weeks 5 to 9)

  • About 1 to 2 weeks after surgery, the pathology report shows the higher-risk features and the team recommends radiation.

  • The mouth heals from surgery, and a radiation planning visit fits a custom mask and maps the treatment.

  • Any needed dental work or extractions are finished and allowed to heal for about 2 weeks before radiation, to lower the long-term risk of a jawbone healing problem called osteoradionecrosis.

  • Radiation ideally starts within 6 weeks of surgery for the best results.

Radiation (about weeks 9 to 15)

  • Radiation is typically given 5 days a week for about 6 weeks. Each visit is short, though the daily travel adds up.

  • Side effects build over the weeks and peak near the end and for a couple of weeks afterward: mouth sores, dry mouth, taste changes, sore throat and tiredness. The care team helps manage them.

  • Some people need a temporary feeding tube when eating becomes too painful; it is usually temporary.

The end of radiation starts the follow-up clock.

Recovery (months 4 to 12)

  • Recovery takes longer than after surgery alone, often several months. Swallowing may dip around the end of radiation and then improve by about 6 months (see dysphagia).

  • Most side effects improve over the following months, though dry mouth can linger.

  • Ongoing swallowing therapy, nutrition support and dental care are important during this time.

  • Whether a scan is done after radiation varies; otherwise imaging is usually done for a symptom or a concern found on exam.

Quality of life on this track

Fewer published numbers exist for this track. Average scores 6 months after surgery (0 to 100, higher is better):

  • Overall: 54 at 6 months.

  • Speech: 69 at 6 months and 68 at 3 years, lower than in people treated with surgery alone in the same study, reflecting the added effect of radiation on the mouth.

  • Swallowing and mood: no published averages for early mouth cancer on these questionnaires were found yet.

Where the numbers come from: a study of people with small tumors and a single involved lymph node, some of whom received radiation after surgery and some of whom did not; about a third had throat (oropharyngeal) rather than mouth cancer. The questionnaires are described on the quality-of-life questionnaires page.

Long-term care

  • Teeth and jaw: dental visits and possible fluoride treatments for life, and a check with the radiation doctor before any tooth extraction.

  • Thyroid: a TSH blood test every 6 to 12 months for the first 3 years after treatment, because neck radiation can slow the thyroid (hypothyroidism).

  • Swallowing and jaw opening: ongoing swallowing and jaw-stretching exercises.

  • Lymphedema (swelling of the face or neck) is common and treatable.

  • Tobacco and alcohol: staying tobacco-free and limiting alcohol lowers the chance of a new cancer.
