		<property:Prompt rdf:datatype="http://www.w3.org/2001/XMLSchema#string">A 38 years old Caucasian male is admitted following complaints for 2 months history of diarrhea.  It is associated with abdominal pain, progressing from the upper to the lower abdomen, and weight loss.  The patient has no previous history of similar illness or surgery. He denies alcohol or tobacco use.  His vital signs are heart rate 82 beats/min, respiratory rate 16/minute, blood pressure 110/70 mm Hg and oral temperature 37.2 C.  Physical examination revealed a distended abdomen with increased bowel sounds and a palpable mass at the left lower quadrant of the abdomen.  Routine laboratory tests revealed no alterations in the principal biochemical parameters, except for the levels of the following tumoral markers:&lt;br&gt;
&lt;br&gt;
CA 19-9 = 85.7 U/ml (normal value: up to 37 U/ml)&lt;br&gt; 
CEA = 13.7 ng/ml (normal value: up to 3 ng/ml)&lt;br&gt; 
CA 50 = 51.3 U/ml (normal value: up to 19 U/ml)&lt;br&gt;
&lt;br&gt;
Abdominal USG revealed a mass of 9 × 5 cm of mixed echogenicity in the proximity of the sigmoid colon with some hypoechoic lymph nodes of increased volume in the adipose adjacent tissue.  It was followed by colonscopy with biopsy, where a polypoid vegetating mass, involving the 2/3 of the intestinal circumference was found in the caecum.  Histopathological examination of the mass showed microscopic aspects of adenocarcinoma.  The abdominal CT with intravenous contrast showed the mass with an increase in the volume of mesenteric lymph nodes.  What will be the line of management in this patient?</property:Prompt>
