Phase II study of sorafenib in patients with relapsed or refractory lymphoma

The safety and activity of the multikinase inhibitor sorafenib were investigated in patients with relapsed or refractory lymphoproliferative disorders who received sorafenib (400 mg) twice daily until disease progression or appearance of significant clinical toxicity. The primary endpoint was overall response rate (ORR). Biomarkers of sorafenib activity were analysed at baseline and during treatment. Thirty patients (median age, 61 years; range, 18-74) received a median of 4 months of therapy. Grade 3-4 toxicities included hand/foot skin reactions (20%), infections (12%), neutropenia (20%) and thrombocytopenia (14%). Two patients achieved complete remission (CR), and two achieved partial remission (PR) for an ORR of 13%. Stable disease (SD) and progressive disease (PD) was observed in 15 (50%) and 11 patients (37%), respectively. The median overall survival (OS) for all patients was 16 months. For patients who achieved CR, PR and SD, the median time to progression and OS was 5 and 24 months, respectively. Compared with patients with PD, responsive patients had significantly higher baseline levels of extracellular signal-regulated kinase phosphorylation and autophagy and presented a significant reduction of these parameters after 1 month of therapy. Sorafenib was well tolerated and had a clinical activity that warrants development of combination regimens.     

Rehabilitation of chronic graft versus host disease in children. A clinical series

The study was aimed at evaluating clinical and functional assessment and results obtained following rehabilitative treatment in children affected by chronic graft versus host disease (cGVHD) after allogeneic transplantation of hemopoietic stem cells (HSCT). From 1999 to 2003 we evaluated 6 children with cGVHD after HSCT presenting severe complications and disabilities. Clinical and functional assessment was performed prior to rehabilitative treatment (T1), at follow-up at 6 (T6) and 12 (T12) months after treatment. Each child received a personalized rehabilitative treatment program based on the use of neuromotor re-education techniques, massotherapy, chest rehabilitation and occupational therapy. Six children presented sclerodermoid skin lesions, joint contractures, anchylosis, respiratory insufficiency, postural and walking alterations which led to reduction in motor performance and autonomy in daily living activity. After 1 year of rehabilitation treatment, 3 patients showed improvement in motor performance, 2 remained stable and 1 patient worsened. Rehabilitative treatment associated with pharmacological therapy has proven to be useful in patients affected by cGVHD. We believe that cGVHD is a pathology which must be seen by a physiatrist as early as possible at onset of first cutaneous signs of cGVHD to limit its invalidating evolution.
