High-dose density neoadjuvant chemotherapy in bulky IB cervical cancer.

Abstract Objective The endpoint of this prospective study is to evaluate response rate, survival and toxicity of high-dose density neoadjuvant chemotherapy (NAC) in bulky IB cervical cancer. Material and methods Between January 1998 and December 2009, 154 women were enrolled into study. Three patients were withdrawn. Of the 151 women, 119 had stage IB2 cervical cancer (78.8%) and 32 had stage IB1 cancer (21.2%) infiltrating the whole cervical stroma. Women received 3–4cycle cisplatin-75mg/m 2 and ifosfamide-2g/m 2 in cases of squamous-cell cancer or cisplatin-75mg/m 2 and doxorubicin-35mg/m 2 in adenocarcinoma every 10days and then underwent radical hysterectomy type III. Patients who had non-resectable disease underwent chemoradiotherapy. Results The overall response rate (reduction of tumor volume more than 50%) was 78.8%. Reduction of tumor volume less than 50% was seen in 15.2%. Tumor progression during chemotherapy occurred in nine patients (6.0%). There were positive lymph-nodes in 26 patients (18.3%) of the 142 that underwent surgery. 38 women underwent adjuvant radiotherapy (26.7%). There were 26 recurrences (17.2%). After surgery 20 women recurred from 142 (14.1%) and after primary radiotherapy 6 from 9 women recurred (66.7%). 25 of 151 women died from disease (16.5%). At the time of the study, surgery was performed in 118 women 5 or more years ago, 19 of them died of disease. Five-year specific survival is 83.6%. Grade 3–4 neutropenia was found in only 7.3% of the women, and grade 3–4 thrombocytopenia were found in 1.3%. Conclusion High-dose density NAC appears to be feasible in the treatment IB bulky cervical cancer and toxicity is acceptable. Adjuvant radiotherapy was used only in 26.7%.
