initial assessment of their condition by specified clinical and laboratory parameters, each of the patients will be treated for 8 weeks at the standard pentoxifylline dose (400 mg po TID).

This protocol is designed as an open label one arm study. (A placebo controlled randomized trial was approved by the IRB but after extensive negotiation, drug and placebo in slow release formulation will not be provided by the manufacturer). Up to fifty patients will be recruited. After initial assessment of their condition by specified clinical and laboratory parameters, each of the patients will be treated for 8 weeks at the standard pentoxifylline dose (400 mg po TID). Objective and subjective response parameters will be re-assessed at the end of the treatment and 8 weeks later for possible decay of response.\n\nIn addition to symptomatic objective and subjective response, blood and urine will be collected for TNF, TGF-beta, and FGF. Cutaneous blood flow and collagen subtyping will be performed on a subset of patients using Laser Doppler, functional MRI techniques and subcutaneous tissue biopsies. We will examine for correlation between clinical response and these biological responses."}, "EligibilityModule"=>{"Gender"=>"All", "StdAgeList"=>{"StdAge"=>["Child", "Adult", "Older Adult"]}, "HealthyVolunteers"=>"No", "EligibilityCriteria"=>"POPULATION CHARACTERISTICS:\n\nRegional advanced postradiation fibrosis of the neck, chest wall, pelvis, or extremities causing measurable impairment of specific function, i.e.: Decreased range of motion, Weakness, Sensory deficit, Pain requiring narcotics, Significantly altered activities of daily living.\n\nNone of these conditions present either before or during radiotherapy or attributed to surgery or chemotherapy.\n\nPatients with prostate cancer allowed if prostate-specific antigen (PSA) is less than 4.0 ng/mL and the last 3 PSA values were stable or decreasing.
