title: Cisplatin and pentoxifylline in advanced or recurrent squamous cell carcinoma of the cervix: a phase II trial of the Gynecologic Oncology Group.
abstract: OBJECTIVE
  The aim of this study was to determine the antitumor activity and toxicity of cisplatin and pentoxifylline in previously treated patients with squamous cell carcinoma of the cervix.
  
  
  METHODS
  A Gynecologic Oncology Group (GOG) Phase II trial of recurrent squamous cell cervical cancer using standard GOG response and toxicity criteria was performed.
  
  
  RESULTS
  A total of 47 patients with advanced or recurrent squamous cell carcinoma of the cervix were entered. The starting dose was 75 mg/m(2) of cisplatin every 21 days and 1600 mg of pentoxifylline PO every 8 h for nine doses during each course. Forty patients were evaluable for response and 44 were evaluable for toxicity. Of the 40 evaluable patients, 37 had received prior radiotherapy and 35 had received prior chemotherapy. A median of three courses were given (range: 1-7). Among evaluable patients, 1 had a complete response (2.5%) and 3 had a partial response (7.5%) for an overall objective response rate of 10%. The complete responder had not previously had chemotherapy. Grade 3 or 4 toxicity was predominantly nausea and vomiting (32%) and hematologic toxicity (23%).
  
  
  CONCLUSIONS
  The combination of cisplatin and pentoxifylline at the dose and schedule tested has limited activity in previously treated advanced or recurrent cervical cancer.
