Note: there is significant overlap between regimens for gastric cancer and esophageal cancer, if you can't find the regimen you're looking for here, please try the esophageal cancer page. If you still can't find it, it is possible that we've moved it to the historical regimens page. For placebo or observational studies in this condition, please visit this page.

• Note: this page contains regimens which were not tested in biomarker-specific populations. The following links will take you to biomarker-specific subpages:
• Regimens for HER2 positive gastric cancer are here.

Regimen variant #1

Study	Dates of enrollment	Evidence	Comparator	Comparative Efficacy
Al-Batran et al. 2008	2003-2006	Phase 3 (C)	FLO	Might have inferior PFS

Note: In contrast to the original reference, some guidelines list 5-FU as being given every 2 weeks rather than the schedule below. Patients had 100% adenocarcinoma histology (20% gastroesophageal junction, 80% gastric).

Chemotherapy

• Cisplatin (Platinol) 50 mg/m² IV over 2 hours once per day on days 1, 15, 29, 43
• Leucovorin (Folinic acid) 200 mg/m² IV over 2 hours once per day on days 1, 15, 29, 43
• Fluorouracil (5-FU) 2000 mg/m² IV continuous infusion over 24 hours, started on days 1, 8, 15, 22, 29, 36 (total dose per cycle: 12,000 mg/m²)

Supportive therapy

• Up to 3 liters normal saline as hydration with cisplatin
• Antiemetic medications per "local protocols"

8-week cycles

Regimen variant #2

Note: the primary reference said every cycle was 15 days, but also said that medications were given every 14 days, so the assumption was made that this more regular schedule was used.

Chemotherapy

• Cisplatin (Platinol) 50 mg/m² IV over 60 minutes once on either day 1 or 2
• Leucovorin (Folinic acid) 200 mg/m² IV over 2 hours once on day 1
• Fluorouracil (5-FU) 400 mg/m² IV bolus once on day 1, then 1200 mg/m² IV continuous infusion over 22 hours (total dose per cycle: 1600 mg/m²)

Supportive therapy

• 1 liter hydration over 3 hours before and after cisplatin
• 5-HT3 antagonist IV prior to cisplatin
• Methylprednisolone (Solumedrol) 120 mg IV 10 minutes prior to cisplatin
• Oral antiemetics and corticosteroids from days 2 to 5

14-day cycle for at least 4 cycles

FULV: 5-FU & LeucoVorin

Regimen variant #1

Study	Dates of enrollment	Evidence	Comparator	Comparative Efficacy
Bouché et al. 2004 (FFCD 9803)	1999-2001	Randomized Phase 2 (E-de-esc)	1. LV5FU2 & Cisplatin 2. LV5FU2 & Irinotecan	Not powered to draw conclusions

Note: the primary reference said every cycle was 15 days, but also said that medications were given every 14 days, so the assumption was made that this more typical schedule was used. Patients had 100% adenocarcinoma histology (70% gastric origin, 30% cardia).

Chemotherapy

• Fluorouracil (5-FU) 400 mg/m² IV bolus once on day 1, then 1200 mg/m² IV continuous infusion over 22 hours (total dose per cycle: 1600 mg/m²)
• Leucovorin (Folinic acid) 200 mg/m² IV over 2 hours once on day 1

14-day cycle for at least 4 cycles

Regimen variant #2

Study	Dates of enrollment	Evidence	Comparator	Comparative Efficacy

Note: to our knowledge, this regimen variant was not tested as an experimental arm in an RCT in this context, prior to becoming a standard comparator arm.

Chemotherapy

• Fluorouracil (5-FU) 2400 mg/m² IV continuous infusion over 46 hours, started on day 1
• Leucovorin (Folinic acid) 100 mg/m² IV once on day 1

14-day cycles
