Title: Dynamic contrast-enhanced MR and PET/CT findings of uterine sarcomatoid carcinoma: a
case report
Version: 0Date: 05 Jul 2020
Reviewer's report:
Overall Comment:
The authors have performed a MRI to a patient with a rare disease condition. Their findings andexperience may serve as a reference for others in the future. However, this is only the findings ofone case and one may not know if these findings would show up in tumours of similar nature.
Suggestions for revision
1/ Use of English needs a major revision2/ Line 20 and line 67: Was pelvic lymphadenectomy performed to remove the metastatic nodes?3/ Line 26-27: What do you mean by diffuse uterine lesions. What are the MRI findings that areparticularly useful to suggest USC?4/ Line 10 and line 41: Are there any publications reporting MRI features of USC?5/ Line 21 and line 76: Did the patient have chemoradiotherapy or systemic radiotherapy andchemotherapy?6/ Line 82-85: It may be educational to explain the difference between USC and carcinosarcoma.Carcinosarcoma is also recognized to be epithelial in origin.7/ Line 102 to 106: MRI characteristics of USC can also be found in other sarcoma and thereforeis not specific. I think it is unrealistic to use MRI to reach a pathological diagnosis. Recognition offeatures that are suggestive of malignant condition is sufficient to assist the surgeon to manage the
patient.
8/ Since the title is on MRI findings, I wonder if there are other details that the authors may finduseful to highlight the sarcomatous nature of the tumour.
