Laryngeal Cancer Timeline: Chemotherapy First, Then Radiation or Surgery

For some advanced laryngeal cancers, a few cycles of chemotherapy are given first to see how the cancer responds. A good response leads to radiation to keep the voice box, and a poor response leads to surgery to remove it.

 

This page is one of the treatment-track timelines for advanced laryngeal cancer. The steps before treatment, how a track is chosen and the long-term follow-up schedule are covered on the laryngeal cancer treatment timelines page.

Who follows this track

Chemotherapy first (induction chemotherapy) is another way to try to keep the larynx. It is used at some centers, especially for larger tumors or cancers with many involved lymph nodes, in people healthy enough for several strong drugs. Its advantage is that the response to chemotherapy helps sort out early who is likely to do well with radiation and who is better served by surgery. With the three-drug combination, about 7 in 10 people still had their larynx at 10 years in a large study. Compared with chemoradiation alone, it adds about 2 months to treatment.

Before treatment (weeks 0 to 3)

Chemotherapy (about weeks 3 to 12)

  • Usually 2 to 3 cycles of chemotherapy, commonly three drugs (docetaxel, cisplatin and fluorouracil), each cycle 3 weeks apart.

  • Side effects include tiredness, nausea, mouth soreness, low blood counts with a risk of infection, hair loss, and effects on hearing and the kidneys. Medicines to support blood counts are often given.

Checking the response (about weeks 9 to 12)

After 2 or 3 cycles, a scope exam and scans show how much the tumor has shrunk and whether the vocal cords move better.

  • Tumor gone or nearly gone: radiation follows to keep the larynx.

  • Tumor partly shrunk: radiation, often with chemotherapy, or surgery, depending on the details.

  • Little or no shrinkage: a total laryngectomy follows, usually with radiation afterward. This happens for about 1 in 7 people. The details of the operation are on the laryngectomy alone timeline.

Radiation (about weeks 15 to 22, after a good response)

  • Radiation 5 days a week for about 7 weeks, often with weekly chemotherapy.

  • Side effects are those of chemoradiation: throat soreness, painful swallowing, hoarseness, dry mouth, skin changes, tiredness and weight loss. A feeding tube is used by some people and is usually temporary.

Recovery (months 6 to 12)

  • A PET-CT scan about 12 weeks after radiation shows whether any cancer remains. If it does, a laryngectomy (salvage surgery) is the usual next step.

  • Swallowing and voice improve gradually over the following months.

Quality of life on this track

In a study of chemotherapy first followed by chemoradiation, average scores (0 to 100; higher is better) were:

  • Overall: 75 before treatment, about 45 at the end of chemoradiation, and 84 at 1 year.

  • Swallowing: 75 before treatment and about 40 to 57 at the end of chemoradiation (depending on the cisplatin schedule); later values were not reported.

  • Mood: 75 before treatment, about 78 to 85 at the end of chemoradiation, and 91 at 1 year.

Speech scores were not reported. Swallowing is shown as 100 minus the score of the head and neck questionnaire, so that higher means better. The questionnaires are described on the quality-of-life questionnaires page.
