How would the duration of 5FU infusion impact response?

Exploratory analysis of the MAGIC trial suggested perioperative chemotherapy was detrimental in this subset of patients. Has availability of IO altere...

Patients with gastric cancer can acquire new targetable mutations on progression. This could aid in additional treatment options in this group which t...

What other molecular tests do you routinely order on such tumors?

If so, what dose-fractionation regimen do you utilize? What are your target volumes?

Do you rebiopsy or use a liquid assay?

Are there factors that would lead you to select either ramucirumab +/- paclitaxel vs T-Dxd vs chemo?

Would your thinking change if the patient continues to be NED after an unplanned chemo break, e.g. for insurance issues?

Is it necessary to test CPS given the FDA approvals are not contingent on CPS %?  If you do test, do you check 28-8 (nivolumab), 22C3 (pembroliz...

Is FOLFOX or 5FU acceptable without XRT if D2 resection? 

Is there such thing a definitive radiotherapy in this setting, or would this be a purely palliative approach? If you would treat, what would your targ...

Provided the patient can have the solitary met treated definitively with SBRT and is otherwise a good surgical candidate

I understand the perioperative trials are not based on tumor regression in cancer cells.

Will you treat only the anastamosis and remnant stomach without elective nodal RT, or will you include elective nodal RT in your treatment fields, ass...

Is there a consensus on the MAGIC v. MacDonald debate?

We use PET for esophageal, but not gastric cancer. GE junction seems like a grey area.
