Reviewer’s report
Title: 
Long-term survival of a patient with liver metastases from clear cell
gastric adenocarcinoma after multimodality treatment including interventional
oncology techniques – case report
Version:

Reviewer's report:
I read the case report with interest submitted by Dr Jugovec and colleagues
delineating a case of a patient with gastric adenocarcinoma with liver metastasis
and their experience and outcome with multimodality therapy.
In general, this is a nicely written case report of a patient with a particular long
survival with gastric adenocarcinoma, and it is worth to publish this article.
- Minor comments
Page 5, second paragraph from below. 
I think there is a typo. 
It should be "the
patient was once again treated" (and not once aging treated)
- Major comments
1. This patient was treated over a long time with multiple therapies. 
I suggest to
summarize the therapies in a table or in a timeline figure to make it easier for the
reader.
2. The authors mentioned multiple times that hepatic resection is performed in
patients with liver metastasis from gastric adenocarcinoma, (background and
discussion paragraph). 
I recommend that the authors state that this is an option
only for "highly selected cases". 
In the time of TACE, SIRT etc., I recommend
that the authors delineate which patient they still operate on and perform liver
resection in such a situation.
3. In the case report paragraph, I recommended the authors should mention
which imaging modality was performed, which did not reveal any distant
metastasis at the beginning, CT scan, PET?
4. From March to July 2011 patient received chemoradiation. 
What was the
radiation dose?
5. Page 5, first line. 
I suggested to rephrase: "In May 2014, a surveillance CT
scan revealed…."
6. Page 6, second paragraph. 
The authors stated that the patient was only 6
months on palliative care. 
Do the authors mean hospice? 
One could argue that
the patient was on palliative treatment since 2012.
