Purpose: To evaluate the toxic effects and antitumour activity of a multidrug regimen with cisplatin, epirubicin and paclitaxel (CEP) as initial therapy in patients with uterine adenocarcinoma.
Patients and methods: Forty-nine patients with histologically-confirmed diagnoses of locally advanced, recurrent or metastatic cervical or endometrial adenocarcinoma entered the study. Treatment consisted of epirubicin (E) given at 70 mg/m2 followed by paclitaxel (P) (175 mg/m2 over three hours) and cisplatin (C) (50 mg/m2), repeated every three weeks. Eligibility criteria also included age < or = 75 years, no previous chemotherapy, no previous radiotherapy to the tumour parameters, bidimensionally-measurable lesions, no previous or ongoing cardiac disease, and renal and liver function within normal limits. Complete blood cell counts were repeated weekly, and tumor response was assessed every three cycles. A maximum of eight courses was administered in responding patients.
Results: From January 1996 to January 1997, 30 patients with endometrial adenocarcinoma and 19 with cervical adenocarcinoma entered the study, for a total of 213 cycles of treatment. In patients with endometrial carcinoma the overall clinical and pathological response rates were 73% (95% CI, range 54%-88%) and 35% (95% CI, range 16%-57%) respectively; in patients with locally advanced cervical carcinoma the overall clinical and pathological response rates were 64% and 62%. WHO grade 3-4 neutropenia occurred in 61% of the patients, with one possible toxic death. Retreatment had to be delayed for at least one week because of persisting neutropenia in 34% of the patients. Mild peripheral neuropathy and stomatitis were observed in 46% and 23% of the patients. One patient presented acute congestive heart failure after the third cycle of treatment.
Conclusion: The high antitumour activity and the good tolerability of CEP suggest that this regimen should be prospectively compared to standard combinations as initial treatment of advanced endometrial carcinoma.
