RADIOTHERAPY
• Historically RT alone had been used to treat pt with unfavourible features
who are not fit for surgery or T4b disease
• Overall, the 5-year survival rate for patients treated with conventional
doses of RT alone is 0% to 10%
• RTOG 85-01 trial-- all patients in the RT-alone arm who received 64 Gy at 2
Gy per day with conventional techniques died of cancer within 3 years.
• Therefore RT alone should generally be reserved for palliation or for
patients who are medically unable to receive chemotherapy
• N 716
• stage cT2 or higher or nodal positive stage (cN+),resectable tumors
• Arm 1– 3×ECF f/b sx f/b 3×ECF (control )
• Arm 2 – 4× FLOT4 f/b sx f/b 4× FLOT4 (study arm)
• median overall survival 50 months(FLOT4) vs 35months(ECF)
(hazard ratio [HR] 0·77; 95% confidence interval)
• Serious advers effect 27% in both group
• Hospitalization due to toxicity 26% ecf (94 pt) and 25% in FLOT4 (
• Conclusion- In locally advanced, resectable gastric or gastro-
oesophageal junction adenocarcinoma, perioperative FLOT improved
overall survival compared with perioperative ECF/ECX
• NCCN – use in selected patients with good performance status
Definitive Chemoradiation Therapy
• It is a treatment option for unresectable ca oesophagus or T4b
disease
• For patients who are not fit for surgery
• In a retrospective comparison, definitive chemoradiation with
paclitaxel and carboplatin resulted in superior OS, disease-specific
survival, locoregional control, and palliation in patients with
unresectable esophageal cancer.
Post operative chemoradiation
• The landmark INT-0116 trial
• Surgery alone vs surgery f/b chemoradiation
• The majority of patients had T3 or T4 tumors (69%) and node-positive
disease (85%)
• After 5 yrs of follow up 5 year OS was 27 month vs 36 month
• The results of the INT-0116 trial established the efficacy of
postoperative chemoradiation in patients with resected gastric or EGJ
adenocarcinoma who have not received preoperative therapy.
HER2
Overexpression identified in development of ca oesophagus
Positivity rate
adenocarcinoma of the esophagus (15%–30%)
SCC (5%–13%)
Higher positivity in GEJ adenocarcinoma than gastric adenocarcinoma
Significantly higher positivity in males as compared to females
testing is recommended for esophageal or EGJ adenocarcinoma
patients at the time of diagnosis if metastatic adenocarcinoma is
documented or suspected
TRANSTUZUMAB
• Used in HER2 overexpression positive advanced gastric and EGJ
adenocarcinoma.
• ToGA trial-- significant improvement in median OS with the addition
of trastuzumab to chemotherapy in HER2 overexpression positive
patients (13.8 vs.11 months, respectively; P = .046)
• HERXO trial-- At a median follow-up of 13.7 months, PFS and OS were
7.1 and 13.8 months, respectively (CAPOX with Transtuzumab)
• NCCN--trastuzumab should be added to first-line chemotherapy in
combination with a fluoropyrimidine and a platinum agent in
patients with HER2 overexpression positive adenocarcinoma
• Fam-trastuzumab deruxtecan can be used as 2nd line in her2 positive
case
RAMUCIRUMAB
a VEGFR-2 antibody
RAINBOW trial and REGARD trail – survival benefit ,can be
considered in 2nd line chemo
NIVOLUMAB
A monoclonal PD-1 antibody
Approved by USFDA on basis of checkmate 649 trail for first line
treatment of her2 negative PD L1 positive oesophageal carcinoma
nivolumab was approved for patients with completely resected
esophageal or EGJ tumors with residual disease who had received
preoperative chemoradiation

Notes de l'éditeur
Adequate nodal dissection for in case of oesophagectomy– 15 nodes
In ge junct 3cm proximal have 100% coverage and 5 cm distal have 94% coverage
As we go more distal chance of abdominal lymph nodal involvement increase
