Background:
- Adrenocortical carcinoma (ACC) is a rare tumor with an incidence of 1.5 to 2 per million people per year. It has a very poor prognosis with an overall 5-year mortality rate of 75 - 90% and an average survival from the time of diagnosis of 14.5 months.
- The treatment of choice for a localized primary or recurrent tumor is surgical resection.
Patients with recurrent or metastatic disease are infrequently curable by surgery alone.
- As with most solid tumors, chemotherapy options have limited benefit, although platinumbased therapies have response rates of 25 to 30%. To date no targeted therapy has been shown to be of any value in this disease.
- The natural history of ACC can vary greatly with some patients surviving only months while others can live with disease for years. The basis for these differing clinical presentations is not known. While one cannot exclude an immune or other host component as responsible for the diverse clinical courses, it is also possible that there may be a genetic basis for this phenomenon. A bio-specimen repository will be a major step towards more comprehensive studies of this very rare and unusual tumor, and allow us to begin to characterize subgroups within the disease.
- Patients with rare tumors seek expert advice in the management of their care. Dr. Fojo has such expertise and is frequently asked to consult in the care of ACC patients throughout the world. A natural history study would establish a more formal mechanism for such referrals, while allowing the systematic collection of epidemiologic data as well as much needed tumor samples.
Objective:
-To characterize the natural history of adrenocortical cancer, and in the process, collect blood, and tissue samples to study genetic/biochemical pathways involved in the development and progression of adrenocortical cancer (ACC).
Eligibility:
- Patients greater than or equal to 12 years of age with biopsy-proven ACC
- Patients greater than or equal to 12 years of age suspected of having ACC
Design/Schema:
- Patients will be offered clinical consultation with treatment recommendations, including standard of care and clinical trial options. Computed tomography scans of the thorax, abdomen and pelvis will be performed for staging purposes as indicated; occasionally, magnetic resonance imaging will be performed for the visualization of lesions in the liver, spine, or other anatomic sites.
- Medical histories will be documented and patients followed throughout the course of their illnesses, with particular attention to patterns of disease recurrence and progression, response to therapies, duration of responses and hormone production in patients with hormone production as a manifestation of their disease. Tumor growth rates will also be calculated throughout the course of the disease.
- Blood and tumor samples will be obtained at baseline and at follow-up intervals when surgery is indicated. Tumor samples may include samples harvested at other facilities during or prior to enrollment on this trial.
- Genetic and epigenetic analysis of tumors and in selected cases expression array analysis will be performed.
