虽然I_b期宫颈癌的治疗效果是很好的,其五年存活率可达80～90%,但淋巴结转移是影响预后的重要因素。具有盆腔淋巴结转移者,既使用了效果最好的手术加放射治疗,平均五年存活率也不过25～30%。盆腔淋巴造影术已被一些著者应用于研究广泛性盆腔淋巴结切除。经过广泛性淋巴结切除后仍然可有相当数量X-线显影的淋巴结遗留。因此应用手术时及术前淋巴结造 Although I_b cervical cancer treatment is very good, the five-year survival rate of up to 80 to 90%, but lymph node metastasis is an important factor affecting the prognosis. With pelvic lymph node metastasis, both the best use of surgery and radiation therapy, the average five-year survival rate, but also 25 to 30%. Pelvic lymphography has been used by some authors to study extensive pelvic lymph node dissection. After extensive lymphadenectomy can still have a considerable number of X-ray imaging of lymph node legacy. Therefore, application of surgery and preoperative lymphadenectomy
