DESCRIPTION
|
Small Cell Cancer of the Large Intestine is an aggressive (fast-growing) cancer that forms in tissues of the intestine and
can spread to other parts of the body. The cancer cells look small and oval-shaped
when looked at under a microscope. Small cell carcinoma of the large intestine represents
.2% to .8% of all colorectal malignancies.
|
DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM/ICD-10-CM CODING
|
Diagnostic testing: The diagnosis of colorectal small cell carcinoma is confirmed by pathology and the
use of immunohistochemistry. Specific staining for CD56, pancytokeratin, LMWK, CK
7 and 19 are usually positive in small cell malignancies.
Early diagnosis depends on:
Physical findings: General symptoms may include:
ICD-9: 209.0
ICD-10: C7A.019
|
PROGRESSION
|
Survival rates are poor, usually less than 2 years.
|
TREATMENT
|
Treatment for colorectal small cell carcinoma is the use of combined chemotherapy
and radiotherapy as is used in small cell carcinoma of the lung.
|
SUGGESTED PROGRAMMATIC
ASSESSMENT*
|
Suggested MER for
Evaluation: The diagnosis of small cell carcinoma of the large intestine is a pathologic diagnosis
which would be confirmed by a pathology report of colonoscopy specimen.
