Thirty-seven cases of colorectal cancer in patients aged 30 years or y
ounger have been treated at the University of Virginia Health Sciences
Center from 1957 through 1992. The present series, comprising patient
s treated from 1978 through 1992, updates a series presented from our
institution comprising patients treated from 1957 through 1977. For th
e 36-year series, 24 patients (65%) were female, and 13 (35%) were mal
e. Sixteen patients (43%) were black, and 21 patients (57%) were white
. Sites of tumor and their frequency were rectosigmoid, 14 (38%), left
colon, five (14%), splenic flexure, two (5%), transverse colon, three
(9%), hepatic flexure, two (5%), right colon, two (5%), and cecum, si
x (16%). Twenty-two patients (59%) presented with abdominal pain, wher
eas 15 (41%) presented with hematochezia or hemoccult positive stools.
The average time of onset of symptoms to diagnosis was 2.3 months. Th
irty-four of 37 patients (92%) presented with advanced stage disease.
Only four patients had precancerous conditions: one each with Gardner'
s Syndrome, Turcot's Syndrome, ulcerative colitis, and villous adenoma
. Twenty-five patients (68%) underwent surgery for cure, and ten (27%)
received palliative procedures. Nothing could be done for two patient
s (5%). Twenty-one patients (57%) had mucinous histology, 13 (35%) had
typical adenocarcinoma, one (3%) had small cell carcinoma, and histol
ogy was unavailable in two (6%). Nodes were negative in only 10 (27%)
patients, of which only three had mucinous histology. There have been
five 5-year survivors and three patients alive and disease free at las
t follow up, ranging from 30 months to 48 months. We conclude that the
re are few survivors among patients aged 30 years or younger with colo
rectal, carcinoma. Most patients present with extensive disease and mu
cinous histology. Lesions are commonly beyond the transverse colon (57
%). Abdominal pain and hematochezia or hemoccult positive stools are t
he most common presenting symptoms. These symptoms should alert the ph
ysician to include colorectal carcinoma in the differential diagnosis
for young patients.
