Actor Stanley Tucci is known for his roles in films such as “The Devil Wears Prada,” “The Hunger Games,” “The Lovely Bones,” “Spotlight,” and “Julie and Julia.” But now he is becoming known for another role — cancer survivor.

In an interview in the September 2021 issue of Virgin Atlantic’s inflight magazine Vera, 60-year-old Tucci revealed that he was diagnosed with cancer at the base of his tongue 3 years ago. “It was too big to operate, so they had to do high-dose radiation and chemo,” he explained.

Tucci was very reluctant to undergo this treatment, since he had seen the effects of this regimen on his first wife, Kate, who died from breast cancer in 2009. “I’d vowed I’d never do anything like that, because my first wife died of cancer, and to watch her go through those treatments for years was horrible,” he said.

He was equally concerned about how his illness would affect his five children. “The kids were great, but it was hard for them,” he noted. “I had a feeding tube for 6 months. I could barely make it to the twins’ high school graduation.”

Now, Tucci said that he is confident that the cancer is unlikely to return: “[Cancer] makes you more afraid and less afraid at the same time. I feel much older than I did before I was sick. But you still want to get ahead and get things done.”

And that’s exactly what he has done for the past 2 years. He launched a new CNN series, “Stanley Tucci: Searching for Italy,” and has written a book, Taste: My Life Through Food, which is set to be released in October.

Cancer of the Tongue
Cancers of the head and neck can form in the oral cavity (including the lips, the front two-thirds of the tongue, the gums, the lining inside the cheeks and lips, the floor of the mouth under the tongue, the hard palate, and the small area of the gum behind the wisdom teeth), the pharynx, the larynx, the paranasal sinuses and nasal cavity, and the salivary glands.

It should be noted that the anterior two-thirds of the tongue is considered part of the oral cavity, while the base of the tongue is part of the oropharynx. The tongue begins to develop around the fourth week of intrauterine life. The anterior portion of the tongue is derived from the first pharyngeal arch, while the base of the tongue originates from the mesoderm of the second, third, and fourth pharyngeal arches. This difference in origin causes the characteristics of these two cancers to be quite distinct, and therefore treatment for each type is quite different.

According to the Surveillance, Epidemiology, and End Results (SEER) Program, the estimated number of new cases of all types of tongue cancer in 2021 was 17,960 (0.9% of all new cancer cases), with an estimated 2,870 deaths. The 5-year relative survival is 68.1% for all stages. For patients with localized disease, the 5-year survival rate is 82.9%.

Clinical Presentation
Cancers at the base of the tongue can grow in either an infiltrative or exophytic pattern. Because the base of the tongue has no pain fibers, these tumors are often asymptomatic until there is significant progression.

Signs and symptoms may include the following:

Pain
Dysphagia
Weight loss
Referred otalgia secondary to cranial nerve involvement
Trismus secondary to pterygoid muscle involvement
Fixation of the tongue that is caused by infiltration of the deep muscle
A mass in the neck

Lymph node metastases are common. Approximately 70% of patients with advanced base-of-the-tongue cancers have ipsilateral cervical lymph node metastases, while ≤30% have bilateral cervical lymph node metastases.

Risk Factors
The most common risk factors for oropharyngeal squamous cell carcinomas (SCCs) include:

Smoking history of more than 10 pack-years and other tobacco use
Heavy alcohol use
Human papillomavirus (HPV) infection, especially HPV 16
Personal history of head and neck cancer

Because cigarette smoking is declining in the U.S., smoking-related oropharyngeal cancer is decreasing; however, oropharyngeal cancer due to HPV infection is increasing. According to the SEER Program’s tissue repository data from 1988 to 2004, the prevalence of HPV-negative oropharyngeal cancers declined by 50%, while HPV-positive cancers increased by 225%.

HPV-positive oropharyngeal cancers may represent a distinct disease entity associated with an improved prognosis. Several studies have indicated that patients with HPV-positive tumors have significantly improved survival.

Oropharyngeal tumors are more likely to be HPV positive compared with oral cavity tumor sites and non-oropharyngeal sites. HPV-positive oropharyngeal cancers predominantly arise in the palatine or lingual tonsils.

Treatment
As with any cancer, the treatment of patients with base-of-tongue cancer depends on a number of factors, including pathology, histology, clinical stage, patient’s age, and general medical condition. In patients with tongue cancer, immunohistochemical staining for p16 status is important.

For early-stage base-of-tongue SCC, surgical resection and/or radiation therapy is frequently used. For advanced-stage tumors, surgical resection may be paired with radiation and chemotherapy or with chemoradiation therapy (CRT). The typical regimen for early- and advanced-stage lesions involves 6 weeks of radiation with a platinum-based chemotherapy agent.

Although effective, radiation therapy and CRT can have significant side effects and can affect quality of life. Common side effects include dry mouth, mucositis, speech issues, dysphagia, aspiration, or respiratory distress. Patients may require a feeding tube or tracheostomy during treatment to protect their nutritional status or airway.

Studies are also being conducted to assess EGFR inhibitors, such as the monoclonal antibody cetuximab (Erbitux), for SCC of the base of the tongue. Immune checkpoint inhibitors are also being investigated.

It is essential that treatment approaches also include treatment of bilateral lymph nodes, either with radiation therapy or surgical resection.
