Abstract
A rare case of upper gastrointestinal hemorrhage due to
synchronous metastases to the esophagus and stomach
from an asymptomatic lung cancer is reported. A 51-yearold white man presented with hematemesis and an
emergency endoscopy revealed submucosal tumorous lesions with central ulcerations in the esophagus and stomach.
A needle aspiration biopsy revealed the presence of cellular
proliferation of adenocarcinoma, which led to the diagnosis
of lung cancer, along with a chest radiograph revealing a
tumor in the right middle lung field. The importance of conducting an upper gastrointestinal endoscopic examination
for staging of patients with lung cancer is stressed.

Introduction
Although gastrointestinal involvement is found in 15%
of patients with primary lung cancer at postmortem, clinically
significant symptoms are rarely present (1,2). The sites of
metastases in the digestive tract are, in descending order,
the small intestine, the stomach, the esophagus and the
colon with little difference amongst them with respect to
frequency of occurrence (3). We report a patient with
otherwise asymptomatic lung cancer who presented with
hematemesis due to synchronous metastases to the
esophagus and stomach. Our case suggests that metastases
to the digestive tract occur more frequently than reports
would indicate. Endoscopic screening should be used
aggressively, and not only for those cases that develop
subjective gastrointestinal (GI) symptoms, in order to assess
the accuracy in staging which in turn may influence the
therapeutic strategy.
Case report
A 51-year-old white man presented to the emergency
department of our hospital with a 3-hour history of
hematemesis. The patient had been a 40 pack-year smoker.
He did not drink alcohol and his only medication was
metoprolol for hypertension. He had no history of
gastrointestinal bleeding or other significant illness.
On initial examination the patient was tachycardic (105
beats/min), but his blood pressure was normal with no
postural changes. The physical examination was otherwise
unrewarding. A nasogastric tube aspirate revealed blood –
stained gastric contents.
Laboratory data on admission revealed hemoglobin
of 11.2g/dL, an hematocrit of 34.6%, a red cell count of
3,830,000/mm3 , a white cell count of 9,700/mm3 and a platelet
count of 367,000/mm3. Serum total protein and albumin
concentrations were 7.1g/dL (normal; 6.5-8.5g/dL) and 3.8g/
dL (normal; 4-4.5g/dL) respectively. Concentrations of blood
urea nitrogen and creatinine were normal, as were the results
of urinalysis. An upper GI endoscopy was performed,
revealing submucosal tumorous lesions with an ulcerated
252
Katsinelos et al
center in the middle of the esophagus (Fig.1) and on the
posterior wall of the upper part of be gastric body (Fig.2).
Because the lesions appeared to the submucosal, aspiration
biopsy was performed with an endoscopic 18-gauge 8mmlong metal needle (Wilson–Cook, Winston – Salem, USA).
The specimen was obtained by puncturing the mucosa and
rapidly passing the needle in and out of the lesion while
aspirating.

Discussion
Fig.2 Endoscopic appearance of a submucosal lesion with an
ulcerated center on the posterior wall of the upper part of the
gastric body.
A chest X – ray showed a mass lesion in the right middle
lung field (Fig.3). Pathologic evaluation of the Papanicolaou
–stained smears from the needle aspiration biopsy revealed
squamous carcinoma cells that closely resembled lung cancer
cells (Fig.4).
In the presence of these metastatic lesions, the lung
cancer was classified as stage IV – tumor, and the patient
was admitted to the department of oncology for
chemotherapy.
Metastases originating from primary lung cancer are most
frequently sited in the contralateral lung (49.8%), liver
(36.9%), adrenal glands (30.8%) and bones (29.4%), while
GI tract metastases are considered rare (4). Upper GI endoscopy is not common practice in the screening of patients
with known primary lung cancer. In most centers, GI
endoscopy is reserved for patients presenting GI symptoms.
However, some suspect that if upper GI endoscopy were to
be used in this setting, the rate of primary lung cancer
metastases to the GI tract would be raised as they would be
recognized in a number of asymptomatic patients.
Our case is interesting in several aspects. The first
manifestation of lung cancer was hematemesis due to
Hematemesis as first symptom of lung cancer
gastroesophageal metastases; the diagnosis was
established by needle aspiration biopsy of the metastases;
and a literature search conducted by the authors in Medline
from 1970 – 2003 did not produce other reports of an
asymptomatic lung cancer presenting with hematemesis due
to synchronous metastases to the esophagus and stomach.
Breast, lung, gastric, prostate and hepatocellular
carcinoma are the most common tumor types to metastasize
to the esophagus (5). In a review of 1000 autopsy cases of
patients with cancer of epithelial origin, in which direct
extension was excluded, esophageal metastases were found
in 31 cases (3). Of these 31, 14 originated from lung cancer,
7 from breast cancer, 4 from gastric cancer and the rest from
miscellaneous primary sites. In another review of autopsies
(6), when direct invasion from gastric, hypopharyngeal and
thyroid tumors was excluded, the 15 cases of secondary
esophageal tumors were made up mostly of lung (7) and
breast (4) cancer.
The occurrence of metastases to the stomach is not as
uncommon as the literature would seem to indicate. In a
study by Oda et al (7) including 6380 autopsies, the primary
tumor sites of metastatic gastric lesions were: lung (84/1235
cases, 6.8%); breast (61/526 cases, 11.6%); esophagus (49/
427 cases, 11.5%); and skin melanoma (21/71 cases, 29.6%).
McNeil et al (8) reported that the most common extraabdominal tumors to metastasize to the GI – tract are lung
cancer (6/78 cases, 7.6%) followed by malignant melanoma
(4/78 cases, 5.2%). These numbers attest to the importance
of an endoscopic examination of the upper GI tract.
Clinically, these patients with gastroesophageal
metastases present with nonspecific symptoms, such as
weight loss, anorexia, abdominal discomfort, nausea and
vomiting (9,10). They may less frequently present with
epigastric pain, melena, dysphagia and postprandial
bloating. Gastrointestinal bleeding may occur and be
massive, in the form of hematemesis, or gradual, producing
iron deficiency anemia (2,7,10,11). Death can result from rapid
blood loss or perforation of the lesion, with subsequent
mediastinitis or peritonitis and hypovolemic shock.
Although most patients with gastroesophageal metastases
have known primary malignancies at presentation, cases do
occur in which the gastroesophageal metastases are the
first clinical presentation.
Lung cancer metastasizes to the GI tract through the
hematogenic and lymphatic route. The initial site of
malignant cell deposition is the submucosal layer of the GI
tract, which is then followed by the formation of new
malignant foci before further spread of the malignancy
(4,7).
Endoscopy has been shown to be an important
diagnostic tool in evaluating metastases to the esophagus
253
and stomach, especially in those patients with normal upper
GI radiographic studies. There are three main morphologic
types of lesions: multiple nodules of varying size with tip
ulceration arising on the crest of normal rugae; submucosal
tumor masses elevated and ulcerated at the apex, giving rise
to the “volcano – like” lesions; and non ulcerated masses
(2,7). Rarely, gastric metastatic lesions may appear as polyps,
flat ulcers or raised plaques.
In our case, hematemesis was the first presentation of
metastases to the esophagus and stomach of an
asymptomatic lung cancer. This fact may enhance the use
of upper GI – tract endoscopy for the more accurate staging
of patients with known lung cancer. The presence of GI
metastases is a sign of generalized metastatic disease and a
very poor prognosis for the patient. It is also believed that
by making an accurate determination of the progression of
the disease, decisions on therapeutic planning will improve.
In conclusion, our case indicates the importance of
conducting an upper GI – tract endoscopy as a standard
procedure in the staging of patients with lung cancer.
