Guidelines for delineation of lymphatic clinical target volumes for high conformal radiotherapy: head and neck region

The success of radiotherapy depends on the accurate delineation of the clinical target volume. The delineation of the lymph node regions has most impact, especially for tumors in the head and neck region. The purpose of this article was the development an atlas for the delineation of the clinical target volume for patients, who should receive radiotherapy for a tumor of the head and neck region. Literature was reviewed for localisations of the adjacent lymph node regions and their lymph drain in dependence of the tumor entity. On this basis the lymph node regions were contoured on transversal CT slices. The probability for involvement was reviewed and a recommendation for the delineation of the CTV was generated

First human face transplantation: 5 years outcomes

Background. The first human facial allotransplantation, a 38-year-old woman, was performed on November 27, 2005. The aesthetic aspect and functional recovery and the risk-to-benefit ratio are evaluated 5 years later. Materials and Methods. The facial transplantation included nose, chin, part of cheeks, and lips. The immunosuppressive protocol included tacrolimus, mycophenolate mofetil, prednisone, and antithymocyte globulins. In addition, donor bone marrow cells were infused on days 4 and 11 after transplantation. Results. The aesthetic aspect is satisfying. The patient has normal protective and discriminative sensibility. She showed a rapid motion recovery, which has remained stable for 3 years posttransplantation. She can smile, chew, swallow, and blow normally whereas pouting and kissing is still difficult. Phonation recovery was impressive therefore the patient can talk normally. Two episodes of acute rejection developed during the first year. Donor-specific anti-human leukocyte antigen antibodies were never detected. Five-year mucosal biopsy showed a slight perivascular inflammatory infiltrate while skin biopsy was normal. The main side effect of the immunosuppressive treatment was a progressive decrease in renal function, which improved after switching from tacrolimus to sirolimus. Moreover, she developed arterial hypertension, an increase in lipid levels, and in situ cervix carcinoma treated by conization. Since 2008, she showed mild cholangitis possibly caused by sirolimus. In September 2010, bilateral pneumopathy occurred and was successfully treated with antibiotics. Conclusion. Despite some long-term complications, which are similar to those reported after solid organ transplantation, the patient is satisfied of her new face and has normal social interaction
