Pattern of failures and clinical outcome of patients with locally advanced cervical cancer treated with a tailored integrated therapeutic approach.

摘要

AIM: To review a tailored treatment with concurrent chemoradiotherapy (CT/RT) or neoadjuvant chemotherapy (NACT) followed by radical hysterectomy in locally advanced cervical cancer. PATIENTS AND METHODS: One hundred and four patients were treated with a tailored therapeutic approach. CT/RT was the standard treatment for patients with stage Ib2-IIb disease aged more than 70 years, or with high surgical risk, as well as for those with stage III-IV disease. NACT followed by radical hysterectomy was the treatment of choice for patients with stage Ib(2)-IIb disease, maximum age of 70 years and good performance status. RESULTS: For the 61 women who underwent CT/RT, 5-year disease-free (DFS) survival and 5-year overall survival (OS) were 62% and 71%, respectively. Patient outcome was associated with the clinical response to CT/RT (complete responders versus others: 5-year DFS, 81% versus 19%, p<0.001; 5-year OS, 84% versus 37%, p=0.001). For the 43 women who underwent NACT, 5-year DFS and 5-year OS were 66% and 75%, respectively. Patient outcome was associated with the pathological response to chemotherapy (optimal responders versus others: 5-year DFS, 89% versus 62%, p=0.03; 5-year OS, 90% versus 72%, p=0.05). CONCLUSION: Tailored treatments obtained satisfactory clinical outcomes in locally advanced cervical cancer. Optimal pathological response to NACT has been found to be a surrogate endpoint of OS. The identification of biological variables able to predict response to NACT is strongly warranted for an accurate selection of patients who may really benefit from chemosurgical treatment.
