Brief summary: RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. Pirfenidone may slow the growth or prevent further development of plexiform neurofibromas.

PURPOSE: Phase I trial to study the effectiveness of pirfenidone in treating young patients who have neurofibromatosis type 1 and plexiform neurofibroma.

Detailed description: OBJECTIVES:

* Determine the maximum tolerated dose or "comparable dose" of pirfenidone in pediatric patients with neurofibromatosis type 1 and inoperable, symptomatic plexiform neurofibromas.
* Determine the toxic effects of this drug in these patients.
* Determine the plasma pharmacokinetics of this drug in these patients.
* Determine, preliminarily, if this drug could be beneficial for pediatric patients with refractory solid tumors.
* Assess the quality of life of patients treated with this drug.

OUTLINE: This is an open-label, multicenter, dose-escalation study.

Patients receive oral pirfenidone three times daily on days 1-28. Courses repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of pirfenidone until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.

Quality of life is assessed at baseline, before course 4, and then after every 6 courses.

PROJECTED ACCRUAL: A total of 3-18 patients will be accrued for this study within 18 months.

Eligibility criteria: DISEASE CHARACTERISTICS:

* Diagnosis of neurofibromatosis type 1 (NF1) AND
* Plexiform neurofibromas

  * Neurofibromas that have grown along the length of a nerve and may involve multiple fascicles and branches (spinal neurofibromas involve 2 or more levels with connection between the levels or extending laterally along the nerve)
  * Potential to cause significant morbidity such as:

    * Head and neck lesions that could compromise airway or great vessels
    * Brachial or lumbar plexus lesions that could cause nerve compression and loss of function
    * Lesions that could result in major deformity (e.g., orbital lesions) or significant cosmetic problems
    * Lesions of the extremity that cause limb hypertrophy or loss of function
    * Painful lesions
* Meets at least 1 other diagnostic criteria for NF1

  * 6 or more cafe-au-lait spots (at least 0.5 cm in prepubertal patients or at least 1.5 cm in postpubertal patients)
  * Freckling in the axilla or groin
  * Optic glioma
  * 2 or more Lisch nodules
  * Distinctive bony lesion (dysplasia of the sphenoid bone or dysplasia or thinning of long bone cortex)
  * First-degree relative with NF1
* Measurable plexiform neurofibromas

  * At least 3 cm in 1 dimension
  * Tumor resection not feasible
* No history of malignant peripheral nerve sheath tumor or other cancer
* No evidence of an active optic glioma requiring chemotherapy or radiotherapy
* No malignant glioma
