A national collaborative group has conducted a multicenter prospective stud
y on the use of a specific glossary for the complications associated with t
he treatment of cervical cancer, which were analytically described in 1989.
This report analyzes the urologic complications with particular reference
to radical surgery in stage IB-IIA cancer cases. In the prospective multice
nter clinical study 2024 patients with frankly invasive cervical cancer wer
e enrolled (IB = 1041; IIA = 308; IIB = 384; IIIA-B = 237; IV = 54). This r
eport considers 1349 patients with stage IB-IIA disease. Treatment modaliti
es in this group of patients were: type III radical surgery in 21.9%; type
III radical surgery followed by radiotherapy in 20.8%; type III radical sur
gery preceded by radiotherapy in 7.3%; type II radical surgery in 3.1%; typ
e II radical surgery followed by radiotherapy in 8.4%; type II radical surg
ery preceded by radiotherapy in 18.8%; surgery plus chemotherapy plus radio
therapy in 3.5%; radiotherapy alone in 16%. In this case series 873 complic
ations were registered, and among these 341 (39.1%) were described in the u
rinary tract. Among 277 bladder complications 47.3% were grade 1; 47.3% gra
de 2, and 5.4% grade 3. Among 64 ureter complications 59.4% were grade 1; 1
7.2% grade 2, and 23.4% grade 3. Distribution of severe urinary complicatio
ns was different according to site (bladder or ureter) and treatment modali
ties (radical surgery alone: bladder 1.3%, ureter 1.3%; radical surgery fol
lowed by radiotherapy: 1.4% bladder, 2.8% ureter; radical surgery preceded
by radiotherapy: 3% bladder, 0% ureter). Different distributions of severe
urinary complication were also observed in respect to stage (IB vs IIA); tr
eatment: elective vs nonelective. In 673 patients treated with radical surg
ery plus or minus radiotherapy 123 relapses were registered (18.2%). Incide
nce of relapse was not different in patients suffering from mild/severe com
plications vs patients without complications. Disease-free survival, death
from tumor, and death from other causes were not different in the group wit
h complications in comparison to the group without complications.
