Short duration neoadjuvant chemotherapy followed by radiotherapy for advanced carcinoma of the cervix: results and prognostic variables.
OBJECTIVE
The value of neoadjuvant chemotherapy in squamous cell carcinomas of the cervix has not been proven. It has been suggested that the potential benefit of this therapy on local and occult metastatic disease could be offset by delaying effective radiation therapy and selection of more aggressive tumor clones. This report examines the potential impact of short duration neoadjuvant chemotherapy on the response and outcome of advanced carcinoma of the cervix.


METHODS
Between 1993 and 1997, 37 patients with advanced squamous cell carcinoma of the cervix (FIGO Stages IIB to IV) were enrolled in a prospective nonrandomized study using short duration neoadjuvant chemotherapy. Median age was 57 years (range: 34-70). Twenty-one patients (57%) had Stage IIB disease, one (3%) had Stage IIIA, 11 (30%) Stage IIIB, and four (11%) had Stage IV disease. The average tumor diameter at presentation assessed by physical examination and by CT scan measurements was 5.3 + 1.9 cm and 5.3 + 1.4 cm, respectively. Patients received three cycles of chemotherapy consisting of cisplatin 50 mg/m2 and vincristine 1 mg/m2 for 1 dose and bleomycin 25 mg/m2 daily for three days. Cycles were repeated every ten days. All patients started definitive radiotherapy within a week from the end of chemotherapy. Radiation therapy consisted of whole pelvis radiotherapy followed by 1-3 sessions of low dose rate brachytherapy.


RESULTS
Response to neoadjuvant chemotherapy was as follows: seven patients (19%) had minor or no response, one patient had progressive disease, and 28 (76%) had more than 50% tumor reduction; 14 of them (38%) had no clinical evidence of residual tumor. Chemotherapy was discontinued in one patient after the second cycle because of significant changes in pulmonary function tests (PFT), and one patient developed a grade 4 urinary complication after radiotherapy. Median follow-up time for the whole group was 24 months (range: 1-67). Five-year actuarial rates of local control and disease-free survival were 47 and 42%, respectively. At three years, 20 patients (54%) were alive or had died without evidence of disease, and 17 (46%) had succumbed to their disease, with a median time to recurrence of 25 months. Stage and response to neoadjuvant chemotherapy had significant impact on survival, while age. tumor size, and menopausal status did not influence survival.


CONCLUSIONS
Our data indicate that short duration chemotherapy followed by definitive radiotherapy is well tolerated and feasible. However, despite a high rate of objective response (76%), and improved survival for responders, there was no obvious long-term survival benefit for the entire group.
