Reviewer's report:
Dear Authors, 
The manuscript is well written. It reports an interesting case of gestational
trophoblastic neoplasia in the cesarean scar managed with the use of ultrasound-
guided focused ultrasound ablation. 
There are few cases in literature of this pathology treating with this method. 
However i have some questions: Why was a hysteroscopy not performed at the
presentation of the patient 1 month after treatment with increasing BHCG?
Hysteroscopy could have had a diagnostic but also a therapeutic value in the
treatment of uterine lesions (even in the case of neoplasm)(PMID:
34007656;PMID: 32878097) . Why was a combined laparoscopic and
hysteroscopic approach not chosen to perform a segmental excision of the
lesion?. The discussion should be expanded with other type of management that
could be used.
