Acute problems during low-dose-rate intracavitary brachytherapy for cervical carcinoma.

ABSTRACT

OBJECTIVE: To estimate the incidence and severity of problems arising during the hospitalization of cervical carcinoma patients undergoing low-dose-rate intracavitary brachytherapy (ICB). METHODS: One hundred seventy ICB implants in 128 cervical carcinoma patients undergoing curative radiation therapy were reviewed. All events during the hospitalization requiring physician evaluation and/or intervention were scored as a "problem" and divided into 10 categories (fever/infection, pain, gastrointestinal, renal, pulmonary, cardiac, dermatologic, gynecologic, endocrinologic, psychiatric). Problems were scored as mild (no significant morbidity, therapy not discontinued), moderate (therapy discontinued but no significant morbidity), or severe (significant morbidity or mortality). Patient and treatment factors were correlated with acute problems. RESULTS: Forty-two implants (24.7%) were associated with acute problems (95% minor, 5% moderate, 0% severe). The most common types were fever/infection (14.1%) and gastrointestinal problems (5. 9%). Other problem types occurred in <3% of implants. No patient or treatment factor including age, comorbid disease, weight, implant duration, or anesthesia type was significantly correlated with acute problems. Patients who developed acute problems had a survival (P = 0.21) and risk of late sequelae (P = 0.74) similar to those of patients without acute problems. CONCLUSION: Problems occur during the hospitalization in approximately one-quarter of cervical carcinoma patients undergoing low-dose-rate ICB. However, most are minor and do not result in morbidity, require discontinuation of therapy, or adversely impact on outcome.
