Latar belakang: Autograft tulang digunakan pada operasi rekonstruksi kasus tumor tulang. Extracorporeal irradiation (ECI) pada tulang digunakan untuk membunuh sel tumor. Namun radiasi juga menimbulkan efek negatif terhadap osteoinduksi dan osteogenensis untuk inkorporasi autograft tulang. Penelitian ini bertujuan mempelajari pengaruh iradiasi dengan dosis 50-300 Gy terhadap kemampuan inkorporas...

In 2007 a 9½-year-old boy was treated with resection, extracorporeal irradiation and re-implantation of the right scapula. He also received chemotherapy. During five year follow-up shoulder function remained largely intact. Subtotal resorption of the scapula occurred, leaving only the glenohumeral joint intact. Sensibility and strength are intact. To date there is no sign of local or metastatic...

Photopheresis is a new extracorporeal photochemotherapy in which the patient's blood or certain blood fraction is exposed to light in the presence of a light-activatable drug. The major engineering elements involved for better system design and patient treatment, such as system model, cell separation, irradiation, and energy measurement, are discussed.

T HERE ARE numerous conflicting concepts in respect to the function, fate and life span of lymphocytes.15 Radiation of segments of the wholebody or of lymphocytes in vitro has long been exploited in the study of lymphocytes.69 However, irradiation of the whole-body or segments injures lymphopoietic tissue and the in vitro environment separates the lymphocyte from homeostatic influences. We reas...

En-bloc resection, extracorporeal irradiation and re-implantation of the irradiated bone have been used to treat 15 patients suffering from primary malignant tumours of bone or cartilage and two with benign lesions. This treatment is an alternative to replacement by prosthesis or allograft bridging techniques. After a mean follow-up of over five years results are encouraging, despite some compl...

Between 1996 and 2003, 16 patients (nine female, seven male) were treated for a primary bone sarcoma of the femur by wide local excision of the tumour, extracorporeal irradiation and re-implantation. An additional vascularised fibular graft was used in 13 patients (81%). All patients were free from disease when reviewed at a minimum of two years postoperatively (mean 49.7 months (24 to 96). The...
