Esophageal and GEJ Adenoca: Consensus on Adjuvant Therapy
T2-3 or N+: Something more than surgery alone should be done
Preop chemo ECF, CF improves overall survival in some but not all trials
– MAGIC (ECF): 13% ↑ OS at 5 yr (esophageal and GEJ 25% pts)
– FFCD / FNLC (CF): 14% ↑ OS at 5 yr (esophageal and GEJ cancer, 180 pts) same as MAGIC, no epirubicin

Esophageal Adenocarcinoma: Consensus on Adjuvant Therapy
Trials focusing purely on esophageal and GE junction cancers
Preop chemo CF failed:
– MRC 0E0-2 (CF): 800 pts, adeno and squam
5 year update: 6% ↑OS
Impacted only on rate of R0 resection
– U.S. INT 113 (CF): 450 pts, adeno and squam
No impact on OS or rate of R0 resection
– EORTC 40954 (CF): 70 pts, adeno
No impact on OS

Esophageal Cancer: Preop Chemo, RT, or Both? Conclusions
Esophageal, GEJ Adeno– Preop ECF Chemo improves survival and is feasible– Preop RT + Chemo: superior OS, more path CR’s
Esophageal Squamous– RT + Chemo:
As primary therapy without surgery is preferred Surgery after chemo RT: in selected patients
Improved local control no improvement in survival

PET Scan Directed Therapy Trial Design: CALGB 80803
T3/4 or N1 Esophageal
Adenoca
PET/CT: Induction Chemo: FOLFOX6
or Carbo/Pacliotaxel
PET-responders: ≥ 35% SUV decrease: continue
same chemo + concurrent RT (5040cGy in 180cGy fx)
PET Scan day 29-35
Surgical resection 6 weeks post-RT
PET- nonresponders: < 35% SUV decrease:
Cross over to alternate chemo + RT (5040cGy in
180cGy fx)
Hypothesis: changing chemo in PET non responding patients will improve pCR
during chemo + RT

Optimal Surgery for Gastric Cancer? D2 resection is the standard of care in Asia
Increasingly in the West D2 resection is considered the standard
Update of Dutch D1 vs D2 resection at 15 years supports D2:

Adjuvant Therapy in Gastric Cancer Improves OS Post op RT + chemo (U.S.), less than a D1-2 resection
– 5FU-LV + RT, INT 116:
10% 5 yr OS, HR 0.65
Pre and post op chemo (U.K.) without RT
– ECF, MAGIC:
13% 5 yr OS, HR 0.75
Post op chemo (Asia): 2 trials, 2000 pts, D2 resection, no RT
– S-1 (Oral 5-FU), ACTS-GC:
13% 5 yr OS, HR 0.67 (2011 update)
– Post op Cape-Oxali , CLASSIC Trial:
14% 3 yr DFS, HR 0.56
Survival improvements with all approaches similar, modest
