Persistence of symptoms+ body weakness= sought
consult and was admitted to our institution (medicine)
Jan.22- Feb.21
EGD- circumferential, nodular, partially obstructing and
friable mass from 35 cm level of esophagus down to the
cardia (41cm level)
Biopsy of esophageal mass- well differentiated squamous
cell carcinoma
Biopsy of cardia of stomach esophageal mass- revealled
esophageal mucosa with severe dysplasia can’t totally
rule out invasive squamous cell carcinoma
Endoscopic guided insertion of NGT done

gastroesophageal junction causing significant
narrowing of its lumen (1/26/09)

Dysphagia
• Difficulty in swallowing, the primary symptom of
esophageal disorders.
• Sensation of sticking or obstruction of the passage of food
through the mouth, pharynx, or esophagus
Harrison’s Principles of Internal Medicine 17th ed. pp 237-239
Dysphagia
 Mechanical due to large bolus or narrow lumen
 Motor due to weakness of peristaltic contractions or
impaired deglutitive inhibition causing nonperistaltic
contractions and impaired sphincter relaxation

Squamous Cell Carcinoma of the
Esophagus
 Most common type of carcinoma of the esophagus –
90%
 Age > 50
 Most symptomatic tumors are quite large by the time
they are diagnosed and have already invaded the wall
or beyond
 20% -upper third, 50% - middle third, and 30% - lower
third of the esophagus
Robbins and Cotran Pathologic Basis of Disease, 7th ed.
Squamous Cell Carcinoma of the
Esophagus
 Most squamous cell carcinomas are moderately to well
differentiated
 Rich lymphatic network in the sub mucosa promotes
extensive circumferential and longitudinal spread
 Areas of metastasis
 upper third - cervical lymph nodes
 middle third - mediastinal, paratracheal, and
tracheobronchial nodes
 lower third - gastric and celiac groups of nodes

Clinical Features
 Insidious in onset
 Produces dysphagia and obstruction gradually and late
 Patient progressively alters their diet from solid to
liquid foods
 Extreme weight loss
 Debilitation
Risk Factors
 Alcohol consumption increases the risk of
squamous cell cancer 10 to 25 times
 Combined cigarette use and alcohol consumption
can increase the risk of squamous cell cancer up to
100-fold
 Ingestion of nitrosamines
 Contamination of food by specific fungi
 Temperature of ingested fluids
 Presence of mechanical irritants to the esophagus
 Silica
 Crushed seeds
Cancer of the Upper Gastrointestinal Tract by Posner et. al., November 2001
 Chronic injury to the esophagus due to:
 Caustic ingestion
 Stasis of foodstuffs in patients with achalasia
 Gastroesophageal acid reflux disease
 Familial abnormality that is associated with squamous
cancer of the esophagus
 Tylosis A, which carries a 25 percent lifetime risk.

DIAGNOSTIC TOOLS
OBJECTIVE: To identify and locate the problem, as well as
determine the extent of the diseasE
1.) CBC, PT/APTT, Electrolytes, TPAG
2.)12 lead ECG
3.)Spirometry
4.)Chest Xray
5.)CT scan
CBC - may show anemia secondary to iron
deficiency or chronic disease.
PT and aPTT - may demonstrate hepatic
insufficiency or nutritional deficiencies; also
detects abnormalities in blood clotting
Electrolytes – should be obtained to determine
imbalances, changes in fluid volume occur preop, intra op and post op
Spirometry - measures lung function,
specifically the measurement of the amount
(volume) and/or speed (flow) of air that can be
inhaled and exhaled.
12 lead ECG – a non invasive device that
records electrical activity of the heart as
well as detects possible abnormalities
Chest X-ray – to determine the condition
of the heart and other adjacent structures.
CT scans - best tool for staging; to
exclude the presence of metastases (M
staging) to the lungs and liver;
determines if adjacent structures have
been invaded.

Esophageal Cancer
 6th most frequent tumor disease worldwide
 Characterized by rapid development and fatal
prognosis in most cases
 Occurrence increases with age with the highest
incidence in the age group 50–70 years
 The disease is diagnosed more frequently in males
than in females (3:5)
 Most frequent histological type is squamous cell
carcinoma


Weight Loss
Nutritional Deficiencies
Dysphagia
Solid food impaction
 Severe stenosis
 Requires endoscopic intervention for disimpaction.
 Regurgitation of food or oral secretions
 Significant luminal obstruction
 Halitosis
 Food stasis
 Regurgitation
American Medical Network: Esophageal Cancer; James C. Chou et.al
 Pulmonary complications from aspiration
 Pneumonia
 Pulmonary abscess
 The tumor mass
 Compression
 Obstruction of the tracheobronchial tree

Leading to dyspnea, chronic cough, and at times
postobstructive pneumonia.
 Esophagoairway fistula may develop with tumor
invasion of the trachea or bronchus.
 Airway fistulas are severely debilitating and are
associated with significant mortality owing to the high
risk of pulmonary complications such as pneumonia and
abscess.
TREATMENT
1. Surgical Management (curative)
 Treatment of Choice for early cancer
 primary goal is complete resection of tumor and involved lymph

nodes
anyone with disease up to T3 N1
must be used with other management to improve survival
esophagectomy: approaches include transthoracic, transhiatal,
transoral route
Radical Resection - Surgical resection that takes the blood
supply and lymph system supplying the organ along with the
organ.
thorascopic tools, laparoscopic tools
gastric/colonic mobilization
Radiation Therapy
 The medical use of ionizing radiation as part of cancer treatment



to control malignant cells
Radiotherapy may be used for curative or adjuvant cancer
treatment
May be used as the primary therapy.
Radiation therapy works by damaging the DNA of cells.
The damage is caused by a photon, electron, proton, neutron, or
ion beam directly or indirectly ionizing the atoms which make
up the DNA chain
Chemotherapy
 Treatment of cancer through Chemicals
 Refers to antineoplastic drugs used to treat cancer or the

combination of these drugs into a cytotoxic standardized
treatment regimen.
Chemotherapy acts by killing cells that divide rapidly, one of the
main properties of cancer cells.
Most chemotherapeutic drugs work by impairing mitosis
It also harms cells that divide rapidly under normal
circumstances which results in the most common side-effects of
chemotherapy.
Some drugs cause cells to undergo apoptosis or programmed cell
death
2. RADIATION & CHEMOTHERAPY
 CURABLE DISEASE
 Combined is superior to radiation alone
 Achieved overall survival rates that equal or exceed
those of historical surgical cohorts (though no trials
comparing them)
 Cisplatin and fluorouracil
 Radiation with chemotherapy
 75% local control rate : improve swallowing
 30% actuarial disease free survival rate
 18% overall survival rate
 High Morbidity from adverse effects
3. Neoadjuvant therapy
 Preoperative radiation and chemotherapy then resection
PALLIATIVE THERAPY
 Most patient with esophageal cancer have advanced
stage at time of initial medical consultation
 <20% survive in 1st year
 Goal of Palliation:
improvement of dysphagia
Pain Management
PALLIATIVE THERAPY
 DISPLACEMENT THERAPY
 ABLATIVE THERAPY
 Dilation therapy
 Contact thermal
 Stenting
 Noncontact Thermal
 Cytotoxic injection
 Photodynamic therapies
DILATION
STENT
PALLIATIVE THERAPY
 Bleeding and esophageal fistula are the most common
adverse effects
 No improvement of pain and anorexia
 Esophageal stent placement can well manage fistulas
from primary malignancy
Enteral Nutrition
 Enteral feeding when feasible
 Attempt to improve functional status before and after
surgery, during chemoradiation
 Oral route: precluded by anorexia, gastric dysmotility,
and generalized debilitation
 Surgical jejunostomy
Prognosis
 The prognosis of esophageal cancer is generally
unfavorable.
 Long-term survival is only approximately 5 % of
patients.
 Of patients who undergo radical esophagectomies,10–20
% survive 5 years.
 In patients with inoperable cancer, the median survival
is 13–29 months.
