*CT: Chemotherapy. The residual tumor was not cover with interstitial BT.

Twenty-two centers (39%) responded to this survey. Median patients treated 58 (3-334p). Six centers treated less than 20 patients in the last 3 years and two hospitals 129 and 334 patients. One center (4,5 %) not provided with BT and with many difficulties in sending patients to other hospitals performs the boost with EBRT (IMRT or SBRT). Five hospitals (22%) perform 100% of planned BT procedures. Of the other 17 hospitals (74%) the median percentage of patients in whom the brachytherapy component could not be performed is 4% (0,3%-66%). The reasons for not perform the BT are listed in the Table 1. Only in one patient was done one of the 2 planned applications due to clinical complications. The patients not candidates for BT were treated with IMRT, SBRT and in 3 cases with surgery.

Conclusion:

Not performing brachytherapy in LACC decrease in the local control and survival. The authors firmly defend the use of brachytherapy as part of the treatment of these patients. Although this survey was only answered by 40% of GINECOR centers, we understand that these data are representative. Despite the strong international recommendations, even there is a group of patients in whom this technique cannot be performed due to clinical, oncological, tumor or technical factors (including lack of technology).
