Childhood Laryngeal Cancer

Histology

Tumors of the larynx are rare. The most common benign tumor is subglottic hemangioma.[1] Malignant tumors, which are especially rare, may be associated with benign tumors such as polyps and papillomas.[2,3]

Clinical Presentation

These tumors may present with the following:
  • Hoarseness.
  • Difficulty swallowing.
  • Enlargement of the lymph nodes of the neck.

Treatment of Childhood Laryngeal Cancer

Rhabdomyosarcoma is the most common pediatric malignant tumor of the larynx and is treated with chemotherapy and radiation therapy.[4] (Refer to the PDQ summary on Childhood Rhabdomyosarcoma Treatment for more information.)
Squamous cell carcinoma of the larynx in children is managed in the same manner as it is in adults with carcinoma at this site, using surgery and radiation therapy.[5] Laser surgery may be the initial treatment used for these lesions. (Refer to the PDQ summary on Laryngeal Cancer Treatment [Adult] for more information about treatment of laryngeal cancer in adults.)

Treatment Options Under Clinical Evaluation for Childhood Laryngeal Cancer

Information about National Cancer Institute (NCI)–supported clinical trials can be found on the NCI website. For information about clinical trials sponsored by other organizations, refer to the ClinicalTrials.gov website.
The following is an example of a national and/or institutional clinical trial that is currently being conducted:
  • APEC1621 (NCT03155620) (Pediatric MATCH: Targeted Therapy Directed by Genetic Testing in Treating Pediatric Patients with Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphomas, or Histiocytic Disorders): NCI-COG Pediatric Molecular Analysis for Therapeutic Choice (MATCH), referred to as Pediatric MATCH, will match targeted agents with specific molecular changes identified using a next-generation sequencing targeted assay of more than 4,000 different mutations across more than 160 genes in refractory and recurrent solid tumors. Children and adolescents aged 1 to 21 years are eligible for the trial.
    Tumor tissue from progressive or recurrent disease must be available for molecular characterization. Patients with tumors that have molecular variants addressed by treatment arms included in the trial will be offered treatment on Pediatric MATCH. Additional information can be obtained on the NCI website and ClinicalTrials.gov website.

Childhood Laryngeal Papillomatosis

General Information

Recurrent respiratory papillomatosis is the most common benign laryngeal tumor in children and is associated with human papillomavirus (HPV) infection, most commonly HPV-6 and HPV-11.[1,2] The presence of HPV-11 appears to correlate with a more aggressive clinical course than does the presence of HPV-6.[3] An Australian survey of pediatric otorhinolaryngologists documented a decline in the incidence of laryngeal papillomatosis after the introduction of HPV vaccinations for adolescent girls and young women aged 12 to 26 years.[4]
These tumors can cause hoarseness because of their association with wart-like nodules on the vocal cords, and they may rarely extend into the lung, producing significant morbidity.[5] Malignant degeneration may occur, with development of cancer in the larynx and squamous cell lung cancer.

Treatment of Childhood Laryngeal Papillomatosis

Papillomatosis is not cancerous, and primary treatment is surgical ablation with laser vaporization.[6] Frequent recurrences are common. Lung involvement, although rare, can occur.[5]
If a patient requires more than four surgical procedures per year, other interventions may be necessary, including the following:
  • Interferon therapy.[7]
  • Immunotherapy with HspE7, a recombinant fusion protein that has shown activity in other HPV-related diseases. A pilot study suggested a marked increase in the amount of time between surgeries.[8]
  • Laser therapy combined with intralesional bevacizumab.[9]
The effectiveness of intralesional cidofovir has not been conclusively demonstrated.[10]
The role of checkpoint inhibitors, such as PD-1 inhibitors, is currently being investigated.[11] Reports with small numbers of patients have documented that in selected cases, the administration of a quadrivalent HPV vaccine can be associated with a complete remission and an increase in the intersurgical interval.[12,13] In contrast, other reports have not documented a therapeutic effect of the quadrivalent HPV vaccine.[14]
In a report of two patients with aggressive recurrent respiratory papillomatosis, treatment with systemic bevacizumab produced good results with minimal toxicity.[15]

Treatment Options Under Clinical Evaluation for Childhood Laryngeal Papillomatosis

Information about National Cancer Institute (NCI)–supported clinical trials can be found on the NCI website. For information about clinical trials sponsored by other organizations, refer to the ClinicalTrials.gov website.
The following is an example of a national and/or institutional clinical trial that is currently being conducted:
  • NCT02632344 (Pembrolizumab for HPV-associated Recurrent Respiratory Papilloma Patients With Laryngeal, Tracheal, and/or Pulmonary Involvement): In this research study, the investigators are determining whether pembrolizumab can restore the natural ability of the immune system to recognize and eliminate HPV-infected cells from the body. Pembrolizumab will be administered at a dose of 200 mg as a 30-minute intravenous infusion every 3 weeks. Treatment will be administered on day 1 of each cycle.

Special Considerations for the Treatment of Children With Cancer

Cancer in children and adolescents is rare, although the overall incidence of childhood cancer has been slowly increasing since 1975.[1] Referral to medical centers with multidisciplinary teams of cancer specialists experienced in treating cancers that occur in childhood and adolescence should be considered for children and adolescents with cancer. This multidisciplinary team approach incorporates the skills of the following health care professionals and others to ensure that children receive treatment, supportive care, and rehabilitation that will achieve optimal survival and quality of life:
  • Primary care physicians.
  • Pediatric surgeons.
  • Radiation oncologists.
  • Pediatric medical oncologists/hematologists.
  • Rehabilitation specialists.
  • Pediatric nurse specialists.
  • Social workers.
  • Child-life professionals.
  • Psychologists.
(Refer to the PDQ Supportive and Palliative Care summaries for specific information about supportive care for children and adolescents with cancer.)
Guidelines for pediatric cancer centers and their role in the treatment of pediatric patients with cancer have been outlined by the American Academy of Pediatrics.[2] At these pediatric cancer centers, clinical trials are available for most types of cancer that occur in children and adolescents, and the opportunity to participate in these trials is offered to most patients and their families. Clinical trials for children and adolescents diagnosed with cancer are generally designed to compare potentially better therapy with therapy that is currently accepted as standard. Most of the progress made in identifying curative therapy for childhood cancers has been achieved through clinical trials. Information about ongoing clinical trials is available from the NCI website.
Dramatic improvements in survival have been achieved for children and adolescents with cancer. Between 1975 and 2010, childhood cancer mortality decreased by more than 50%.[3] Childhood and adolescent cancer survivors require close monitoring because cancer therapy side effects may persist or develop months or years after treatment. (Refer to the PDQ summary on Late Effects of Treatment for Childhood Cancer for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.)
Childhood cancer is a rare disease, with about 15,000 cases diagnosed annually in the United States in individuals younger than 20 years.[4] The U.S. Rare Diseases Act of 2002 defines a rare disease as one that affects populations smaller than 200,000 persons. Therefore, all pediatric cancers are considered rare.
The designation of a rare tumor is not uniform among pediatric and adult groups. Adult rare cancers are defined as those with an annual incidence of fewer than six cases per 100,000 people, and they are estimated to account for up to 24% of all cancers diagnosed in the European Union and about 20% of all cancers diagnosed in the United States.[5,6] Also, the designation of a pediatric rare tumor is not uniform among international groups, as follows:
  • The Italian cooperative project on rare pediatric tumors (Tumori Rari in Eta Pediatrica [TREP]) defines a pediatric rare tumor as one with an incidence of less than two cases per 1 million population per year and is not included in other clinical trials.[7]
  • The Children's Oncology Group has opted to define rare pediatric cancers as those listed in the International Classification of Childhood Cancer subgroup XI, which includes thyroid cancer, melanoma and nonmelanoma skin cancers, and multiple types of carcinomas (e.g., adrenocortical carcinoma, nasopharyngeal carcinoma, and most adult-type carcinomas such as breast cancer, colorectal cancer, etc.).[8] These diagnoses account for about 4% of cancers diagnosed in children aged 0 to 14 years, compared with about 20% of cancers diagnosed in adolescents aged 15 to 19 years.[9]
    Most cancers within subgroup XI are either melanomas or thyroid cancer, with the remaining subgroup XI cancer types accounting for only 1.3% of cancers in children aged 0 to 14 years and 5.3% of cancers in adolescents aged 15 to 19 years.
These rare cancers are extremely challenging to study because of the low incidence of patients with any individual diagnosis, the predominance of rare cancers in the adolescent population, and the lack of clinical trials for adolescents with rare cancers.
Information about these tumors may also be found in sources relevant to adults with cancer such as the PDQ summary on Laryngeal Cancer Treatment (Adult).
