Publikováno v: Cancer. 80:477-488

BACKGROUND Lymphoma of the nasal cavity and paranasal sinuses is a rare presentation of extranodal lymphoma with a natural history that is not well characterized in this era of combination chemotherapy. The goals of this retrospective study were 1) t

Low dose rate brachytherapy in the treatment of cervical carcinoma

Autor: Patricia J. Eifel, Mark D. Logsdon

Publikováno v: Hematology/oncology clinics of North America. 13(3)

Radiation therapy plays a central role in the treatment of invasive cervical carcinoma. Early invasive tumors (stages IA2, IB1, and small stage IIA lesions) are managed with either radical surgery or irradiation. More locally advanced tumors (stages
