Tumor staging

T1- confined to mucosa/submucosa

T2- extends to muscularis propria

T3- extends into surrounding tissue

T4 - involves major vessels, pleura, pericardium

Nodal staging

N0 - no nodes involved

N1 - local nodes involved

N2 - distant nodes involved

Esophagectomy

Combined modality Pre-operative chemo-radiation >>> esophagectomy Esophagectomy >>>> Post-operative chemo-radiation

Non surgical Definitive chemoradiation

What are the usual sites of recurrence Local distant

Benefits Palliative chemo ± radiation

▪ survival benefit▪ Quality of life

Treatment of recurrence in lymph node outside the initial field of initial radiotherapy

How- Physical Exam- what signs to look for CT chest/abdomen- what findings to look for EGD – what symptoms should prompt it Serum CEA levels- ? In which patients EUS - ? role

How often Suggested protocols for follow up

A 52 year old accountant with known history of Barrett’s esophagus and symptomatic reflux

surveillance endoscopy. 5 cm segment of Barrett’s esophagus proximal to the GE

junction. ▪ Biopsy - Multiple foci of HGD

1.5 cm sessile polypoid lesion at the GEJ▪ Biopsy- Invasive adenocarcinoma.

Page 8: Moderators: David Cort, MD Alex Denes, MD Panelists: Stephen Swisher, MD, PhD Edward Lin, MD

T1- confined to the mucosa and submucosa and sparing the muscularis propria.

N0 – no enlarged lymph nodes

Page 9: Moderators: David Cort, MD Alex Denes, MD Panelists: Stephen Swisher, MD, PhD Edward Lin, MD

PET/CT: No nodal or distant metastases

He undergoes esophagectomy without complications (R0 resection)

Surg path: T1, N0, (M0) moderately differentiated adenocarcinoma, No lympho-vascular infiltration multiple foci of Barrett’s all margins clear of tumor

T1N0 GEJ

The cure rate 80-90%.

If EMR or radiation cure rate 60-70% (then regular EGD is indicated).

Q 6 months for the first 2 years, then annual

physical exams with routine blood work.

Imaging only when clinically indicated.

Page 13: Moderators: David Cort, MD Alex Denes, MD Panelists: Stephen Swisher, MD, PhD Edward Lin, MD

Repeat endoscopy 1 year after surgery to rule out residual Barrett’s or dysplasia

No CT Scan, CXR or PET scan unless symptoms because of low likelihood of distant mets with T1N0, LVI negative

A 65 year old house-wife with history of GERD presents with progressive dysphagia

EGD: An irregular, non obstructing, ulcerated mass in the

distal esophagus. Biopsy: Moderately differentiated adenocarcinoma

EUS: T3 tumor (infiltrating muscularis propria) No enlarged lymph nodes

PET/CT: intense FDG uptake in the distal esophageal mass no lymph node or distant metastases

Planned treatment: Pre-operative chemoradiation followed by surgery

Patient recieves combined modality therapy with radiation and chemotherapy Follow up EGD:

▪ no residual mass and biopsy shows only radiation effect.

Patient is now reluctant about proceeding with esophagectomy

Page 20: Moderators: David Cort, MD Alex Denes, MD Panelists: Stephen Swisher, MD, PhD Edward Lin, MD

1. Convince the patient to proceed with surgery as originally planned

2. Give additional chemo-radiation to full dose

3. Can wait and see how the patient performs

4. None of the above

A 48 year old high school teacher presents with progressive dysphagia and weight loss

EGD: large ulcerated nearly circuferential mass in the lower third of

the esophagus. Biopsy: Moderate to poorly differentiated adenocarcinoma

with lymphovascular infiltration.

PET/CT: Intense FDG uptake in paraesophageal lymph nodes. No distant metastases.

EUS: T3 tumor (Nearly circumferential mass, extension into the

adventitia) N1 (multiple enlarged regional lymph nodes)

Page 28: Moderators: David Cort, MD Alex Denes, MD Panelists: Stephen Swisher, MD, PhD Edward Lin, MD

T3N1 tumor

Page 29: Moderators: David Cort, MD Alex Denes, MD Panelists: Stephen Swisher, MD, PhD Edward Lin, MD

Treatment: combined modality therapy with radiation and

chemotherapy.

Follow up EGD 75% regression of the mass. Biopsy: residual adenocarcinoma.

Esophagectomy R0 resection Path:

▪ Residual moderately differentiated adenocarcinoma, ▪ foci of carcinoma in 3 regional lymph nodes.

Page 30: Moderators: David Cort, MD Alex Denes, MD Panelists: Stephen Swisher, MD, PhD Edward Lin, MD

1. Follow up with EGD and CT scan every 3 months

2. Follow up with EGD and CT scan every 6 months

3. Additional radiation therapy to maximal dose

4. Combination salvage chemoXRT

A 68 year old retired carpenter with a history of CAD, CABG, CHF, COPD, and DM presents with progressive GERD symptoms. No dysphagia or weight loss.

EGD: distal esophagitis with an area of ulceration just proximal

to the GE junction Biopsy: Moderately differentiated adenocarcinoma.

EUS: T2 N0tumor

Page 33: Moderators: David Cort, MD Alex Denes, MD Panelists: Stephen Swisher, MD, PhD Edward Lin, MD

PET/CT: No abnormal FDG uptake in paraesophageal lymph

nodes. No distant metastases.

Surgical evaluation: Not candidate for resection due to co-morbidities

Treatment: Completes full course of combined chemotherapy and

radiation.
