Questions to Ask About Head and Neck Cancer Treatment

"Head and neck cancer" is a family, not one disease. Oral cavity, larynx, hypopharynx, nasopharynx, salivary gland, sinonasal and oropharyngeal tumors differ in how they are staged, whether HPV matters, and which operations and drug treatments apply. The evidence quoted below is drawn from NCI's PDQ summary on adult oropharyngeal squamous-cell cancer, meaning cancer of the throat behind the mouth, including the tonsils and base of the tongue. Use it as a model for the kind of question to ask; check the answers against the summary for your own primary site before treating any figure here as yours. If nobody has told you the exact site and cell type yet, that is the first question.

For oropharyngeal tumors this is the central decision, and NCI treats it as genuinely open. For early stage disease it says a single treatment is preferred. It also says that for base of tongue tumors, function was historically better after radiation than after surgery.

Transoral surgery, done through the mouth and including robotic surgery, is being used more. NCI says comparisons that were not randomized suggest better quality of life with minimally invasive surgery than with primary radiation.

NCI pools 6,400 people with cancer at the base of the tongue, treated between 1970 and 2000. This is historical, nonrandomized data: people were not assigned to surgery or radiation by chance, so sicker or healthier patients may have been steered to one arm. Five-year survival was 49 percent with surgery and 52 percent with radiation, a difference that was not significant.

The difference was in harm. Severe complications occurred in 32 percent of the surgery group and 3.8 percent of the radiation group. Fatal complications occurred in 3.5 percent and 0.4 percent.

For tonsil cancers in the same analysis, severe complications were 23 percent with surgery and 6 percent with radiation. Survival again looked similar.

Those figures come from an older era of surgery. That is exactly why it is fair to ask how your own surgeon's results compare today.

HPV status matters in oropharyngeal cancer, and the p16 stain is one marker linked to it. NCI describes a trial of transoral surgery followed by standard or low-dose radiation in HPV-positive disease.

Ask what your result means. Ask whether a trial is open to you, and what joining would mean.

NCI reports on intensity-modulated radiation. Moderate or worse dry mouth affected 55 percent at six months, 25 percent at one year and 16 percent at two years.

Ask whether your plan spares the parotid glands (the large salivary glands in front of the ears), and whether it keeps dose off the muscles you swallow with.

In a study NCI reports, jawbone breakdown occurred in 6 percent of people.

Ask whether you need a dental assessment before treatment begins, and how much healing time is needed before the first session.

NCI describes a trial of 564 people with advanced neck nodes. One group had a planned neck dissection. The other was watched with PET-CT scans and operated on only if needed.

Far fewer operations were done in the scan group, 54 against 221. Two-year survival was 84.9 percent in one group and 81.5 percent in the other, so it was similar. NCI says the trial met its bar for noninferiority, meaning scan-guided watching was shown to be no worse.

Ask whether that approach applies to you.

• Is surgery or radiation the better first step for my tumor?
• What are your own complication rates for this operation?
• Is my tumor HPV or p16 positive, and what does that mean?
• Is there a clinical trial I could join?
• Will my radiation spare my salivary glands?
• Can my dental work be done before radiation starts?
• Do I need a neck dissection, or can scans guide that?
