kholm entre 1993 et 1996 pour un cancer de prostate localisé, et
contactés par voie de questionnaire concernant leur symptomatolo-
gie digestive, urinaires et sexuelle 29 à 59 mois après la radiothéra-
pie, les auteurs remarquaient la fréquence des comorbidités, en par-
ticulier le diabète, l'hypertension et autres comorbidités cardio-vas-
culaires, la dépression, parmi les patients ayant des effets secondai-
res des traitements [18]. Dans notre série, nous ne confirmons pas
cette donnée, puisqu’aucun des patients n’avaient les comorbidités
sus-citées.
CONCLUSION
Des complications sévères surviennent chez 7% des hommes traités
par radiothérapie adjuvante conformationnelle. Ces complications
surviennent à long terme, le délai médian de survenue étant de 25
mois. De plus, des complications peuvent survenir très tardivement
après radiothérapie, ce qui a conduit à une sous estimation de leur
fréquence. Ces complications sont difficiles à traiter et motivent des
hospitalisations pour réaliser des soins itératifs et lourds.

SUMMARY
Severe (RTOG grades 3 or 4) long-term complications of adjuvant
radiotherapyafter total prostatectomy.
Objective:Study of the incidence of severe long-term gastrointesti-
nal (GI) and genitourinary (GU) complications of conformal radio-
therapy after total prostatectomy for localized prostatic adenocar-
cinoma.
Material and Method: From 1991 to 2000, 114 patients with a mean
age of 62 years (range: 45-82 years) were treated by total prostatecto-
my followed by adjuvant radiotherapy. The mean dose of radiotherapy
was 65 Gy (range: 58-72 Gy). The mean interval between prostatecto-
my and radiotherapy was 10 months (range: 2-28 months). Patients
were reviewed every 6 months. We studied severe complications (RTOG
grade 3 or 4) occurring after treatment. The mean follow-up was 74
months (range: 32-132 months).
Results:Eight patients (7%) treated by adjuvant radiotherapywith a
mean dose of 65.5 Gy (range: 59-70 Gy) developed long-term severe
complications. The mean time to onset of complications was 25 months
(range: 5-72 months). Three patients developed gastrointestinal com-
plications (2 cases of radiation proctitis and 1 anal stricture). Five
patients developed genitourinary complications (4 cases of radiation
cystitis and 1 urethral stricture). These eight patients received multiple
transfusions and required surgical or endoscopic procedures. Most
patients were hospitalized on several occasions for periods ranging bet-
ween 3 days and 1 month.
Conclusion:Adjuvant radiotherapy after total prostatectomy is asso-
ciated with severe long-term complications in 7% of cases. When they
occur, these complications generally require repeated major urological
and gastrointestinal surgery.
Key-Words:Prostatic neoplasms, radiation injuries, adjuvant radiothe-
rapy, prostatectomy..
