title: Is there still a role for lymphography in the management of early stage carcinoma of the cervix?
abstract: The value of lymphography in the management of carcinoma of the cervix is controversial and in many institutions has ceased to be used as part of routine staging. We present the results of 103 patients with carcinoma of the cervix treated by radical radiotherapy alone at the Royal Marsden Hospital between 1984 and 1990 all of whom had a staging lymphogram and computed tomography (CT) of the abdomen and pelvis as part of their routine staging prior to therapy. Our results show that 72 patients (70%) had no involved nodes detected on either CT or lymphography (LG--ve/CT--ve) while 16 patients (15.5%) were thought to have involved lymph nodes on lymphography alone but not on CT (LG+ve/CT-ve). The remaining 15 cases (14.5%) had involved lymph nodes on both CT and lymphography (LG+ve/CT+ve). There were no patients shown to have involved lymph nodes on CT with a negative lymphogram. Survival analysis on these three groups showed that patients in the LG+ve/CT+ve group did worse than the other two groups with only a 28% 5 year survival compared with 60% (LG-ve/CT-ve group) and 64% (LG+ve/CT-ve group) (p < 0.1). This effect of lymph node involvement disappeared in a multivariate analysis using Cox regression when stage came out as the strongest factor affecting survival. After controlling for stage, a further analysis of patients with only stage I and II disease has shown that patients who were LG+ve/CT+ve still did significantly (p < 0.05) worse (30% 5 year survival) than the other two groups: LG-ve/CT-ve group altered clinical management in 5/6 patients with stage I or IIA disease who avoided radical surgery and who were given a parametrial boost to the site of lymph node involvement. The possible benefit of this additional treatment to explain the higher survival rate of patients in the LG+ve/CT-ve group is discussed further. We conclude that lymphography still has a limited role to play in patients with early stage disease (I or IIA) who do not appear to have involved lymph nodes on CT scanning.
