La chirurgie ganglionnaire dans les cancers de l'utérus

Uterine cancer can metastasize to both the pelvic and para-aortic levels. No one questions the diagnostic and prognostic value of lymphadenectomy, but its therapeutic value is still open to debate. In early cervical cancer (<4 cm.), pelvic lymphadenectomy is a routine part of radical hysterectomy. If pelvic lymph nodes show involvement, one can propose an extension of the lymphadenectomy to the para-aortic level. Studies of sentinel lymph node identification and biopsy at this level are currently under way. The standard treatment of cervical cancer > 4 cm is radiotherapy. A pre-radiation laparoscopy to investigate lymph node involvement at the lumbo-aortic level may help to define the extent of the radiation field.For endometrial cancer, the role and benefit of lymphadenectomy are much less clear since these patients often have major co-morbidities which increase the risk of complications from an extended lymph node dissection.
