Primary lung tumors are rare in children and histologically quite diverse. When epithelial cancers of the lung occur, they tend to be of advanced stage, with prognosis dependent on both histology and stage. Most primary lung tumors are malignant. In a review of 383 primary pulmonary neoplasms in children, 76% were malignant and 24% were benign. A review of primary malignant epithelial lung tumors using the National Cancer Data Base found that the most common primary malignant pediatric lung neoplasms were carcinoid tumors (63%) followed by mucoepidermoid carcinoma of the lung (18%).
Tracheobronchial tumors are a heterogeneous group of primary endobronchial lesions, and although adenoma implies a benign process, all varieties of tracheobronchial tumors on occasion display malignant behavior. The following histological types have been identified (refer to Figure 1):[1,2,3,4,5,6,7]

With the exception of rhabdomyosarcoma, tracheobronchial tumors of all histological types are associated with an excellent prognosis after surgical resection in children, even in the presence of local invasion.[1,2]; [Level of evidence: 2A]
The presenting symptoms of a tracheobronchial tumor are usually caused by an incomplete tracheobronchial obstruction and include the following:
Because of difficulties in diagnosis, symptoms are frequently present for months, and, occasionally, children with wheezing have been treated for asthma, with delays in diagnosis for as long as 4 to 5 years.
Metastatic lesions are reported in approximately 6% of carcinoid tumors, and recurrences are reported in 2% of cases. Atypical carcinoid tumors are rare but more aggressive, with 50% of patients presenting with metastatic disease at diagnosis.[2,3] There is a single report of a child with a carcinoid tumor and metastatic disease who developed the classic carcinoid syndrome. Octreotide nuclear scans may demonstrate uptake of radioactivity by the tumor or lymph nodes, suggesting metastatic spread.
The management of tracheobronchial tumors is somewhat controversial because tracheobronchial tumors are usually visible endoscopically. Biopsy of these lesions may be hazardous because of the risk of hemorrhage. New endoscopic techniques have allowed biopsy to be performed safely;[5,6] however, endoscopic resection is not recommended except in highly selected cases.[6,7,8] Bronchography or computed tomography scan may be helpful to determine the degree of bronchiectasis distal to the obstruction since the degree of pulmonary destruction may influence surgical therapy.
Cancer in children and adolescents is rare, although the overall incidence has been slowly increasing since 1975. Referral to medical centers with multidisciplinary teams of cancer specialists experienced in treating cancers that occur in childhood and adolescence should be considered. 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:
(Refer to the PDQ Supportive and Palliative Care summaries for specific information about supportive care for children and adolescents with cancer.)
The American Academy of Pediatrics has outlined guidelines for pediatric cancer centers and their role in the treatment of pediatric patients with cancer. 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 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 current standard therapy. 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%. Childhood and adolescent cancer survivors require close monitoring because side effects of cancer therapy 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. The U.S. Rare Diseases Act of 2002 defines a rare disease as one that affects populations smaller than 200,000 people. Therefore, all pediatric cancers are considered rare.
The designation of a rare tumor is not uniform among pediatric and adult groups. In adults, rare cancers are defined as those with an annual incidence of fewer than six cases per 100,000 people. They 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:
Most cancers in subgroup XI are either melanomas or thyroid cancer, with other 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 number 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.
Conservative pulmonary resection, including sleeve segmental resection, when feasible, with the removal of the involved lymphatics, is the treatment of choice.[1,2]; [Level of evidence: 2A] Chemotherapy and radiation therapy are not indicated for tracheobronchial tumors, unless evidence of metastasis is documented or the tumor is the rhabdomyosarcoma histological type.
Treatment options for tracheobronchial tumors, according to histological type, are as follows:
(Refer to the PDQ summary on Childhood Gastrointestinal Carcinoid Tumors Treatment for information about other neuroendocrine carcinoid tumors.)

The following is an example of a national and/or institutional clinical trial that is currently being conducted:
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.
