2. INTRODUCTION
Tumors of the colon and rectum are
relatively common; the colorectal area (the
colon and rectum combined) is now the third
most common site of new cancer cases in
the United States. It is the second leading
cause of cancer death in both men and
women. Improved screening strategies have
helped reduce the number of deaths from
colon cancer in recent years.
3. COLORECTAL CANCER
•Colorectal cancer is the cancer of colon
and rectum. It is related to large intestine.
Colon forms the major part of large
intestine and rectum is the lower part.
•Colorectal cancer is more common in
western countries. It occurs more
frequently after age 50. The incidence
continues to rise with increasing age.
4. INCIDENCE
In the United States, almost 150,000
new cases and 52,000 deaths from
colorectal cancer occur annually. The
lifetime risk of developing colorectal cancer
is 1 in 17. Incidence increases with age (the
incidence is highest in people older than 85
years) and is higher in people with a family
history of colon cancer and those with IBD
or polyps.

relative)
•Personal h/o inflammatory bowel disease
•Personal h/o colorectal cancer, diabetes
mellitus
•Family or personal h/o familial
adenomatous polyposis (FAP)
•Family or personal h/o hereditary
nonpolyposis colorectal cancer (HNPCC)

7. RISK FACTORS (Conti…)
Dietary risk factors for the development
of colorectal cancer
•Increased risk factor :
o Red meat: Carcinogenic amines formed
during cooking.
o Saturated animal fat
o High fecal bile acid and fatty acid levels.
o May affect colonic prostaglandin turnover.
8. RISK FACTORS (Conti…)
•Decreased risk factors
o Dietary fibre: Effects vary with fibre type.
o Fruit and vegetables:
o Green contain anticarcinogens,
e.g. glucosinolates and flavonoids.
o Little evidence for protection from vitamin
A, C, E.
o Calcium: Binds and precipitates fecal bile
acids.
o
9. ETIOLOGY
The exact cause of colorectal cancer is
unknown.
Patient suffering from inflammatory
bowel disease is at higher risk
Family history.
Diet and decreased bowel movement has
been implicated as a causative factor.
10. STAGES OF COLORECTAL CANCER
• Stage I
Cancer occurs through the superficial lining
of the colon or rectum. It does not spread
beyond the colon wall or rectum.
• Stage II
Cancer occurs into and through the wall of
the colon or rectum. It does not spread to
nearby lymph nodes.
11. STAGES OF COLORECTAL CANCER
• Stage III
Cancer has invaded nearby lymph nodes
but it is not affecting other parts of the
body.
• Stage IV
Cancer has spread to distant sites for
instance to liver or lung.
14. Dukes' Classification-Modified
Staging System
•Class A: Tumor limited to muscular mucosa
and submucosa
•Class B₁: Tumor extends into mucosa
•Class B₂: Tumor extends through entire
bowel wall into serosa or pericolic fat, no
nodal involvement
•Class C₁: Positive nodes, tumor is limited to
bowel wall
15. •Class C2: Positive nodes, tumor extends
through entire bowel wall
•Class D: Advanced and metastasis to liver,
lung, or bone Another staging system, the
TNM (tumor, nodal involvement, metastasis)
classification, may be used to describe the
anatomic extent of the primary tumor,
depending on:
oSize, invasion depth, and surface spread
oExtent of nodal involvement
16. NM Classification of Colorectal Cance
T Primary Tumor
Tx Primary tumor cannot be assessed because of incomplete
information.
Tis Carcinoma in situ. Cancer is in earliest stage and has not
grown beyond mucosa layer.
T1 Tumor has grown beyond mucosa into the submucosa
T2 Tumor has grown through submucosa into muscularis
propria.
T3 Tumor has grown through the muscularis propria into the
subserosa but not to neighboring organs or tissues.
T4 Tumor has spread completely through the colon or rectal
17. N Lymph Node Involvement
Nx Lymph nodes cannot be assessed.
N0 No regional lymph node involvement
is found.
N1 Cancer is found in one to three nearby
lymph nodes.
N2 Cancer is found in four or more
nearby lymph nodes.
18. M Metastasis
Mx Presence of distant metastasis cannot
be assessed.
M0 No distant metastasis is seen.
M1 Distant metastasis is present.
19. PATHOPHYSIOLOGY
Cancer occurs in the following areas
Cecum, ascending colon, transverse colon,
descending colon, Sigmoid colon and
rectum
All colorectal cancer is adenocarcinomas
that begin as adenomatous polyps.
All adenomas are dysplastic and considered
premalignant lesions even though only 5%
actually become malignant.
20. Adenomas may present in various shapes
and configuration. They are round and
polypoid but may be more elongated and
have stalks.
Infrequently, adenomas appear flat or
even depressed over times; lesions
penetrate the colon wall and extend into
surrounding tissue.
Most tumors develop in the rectum and
sigmoid colon, although any portion of
21. Tumors grow undetected until symptoms
slowly and insidiously appear.
• Disease spread by several methods.
• It may spread locally into deeper layers
of the bowel wall, reaching the serosa
and mesenteric fat.
• Tumors may enlarge in the lumen of
bowel and spread through the
lymphatics' or circulatory system.
22. Liver and lungs are the major organs of
metastasis. Other includes adrenal glands,
kidneys, skin, bone and brain.
In addition to direct invasion and spread
through the lymphatic and circulatory
system, It can also spread by peritoneal
seeding during surgical resection of the
tumor.
Seeding of the tumor can occur when the
tumor extends through the serosa or during
24. CLINICAL MANIFESTATIONS
CRC has an insidious onset, and
symptoms do not appear until it is
advanced. Common manifestations
include iron-deficiency anemia, rectal
bleeding, abdominal pain, change in
bowel habits, and intestinal obstruction or
perforation.
Physical findings may include the
following: Early disease: Nonspecific
findings (fatigue, weight loss) or none at
25. More advanced : Abdominal tenderness,
palpable abdominal mass, hepatomegaly,
ascites
Bleeding occur both right-and left-sided CRC.
Bleeding on the right side, more common
than the left, is often unrecognized and an
early manifestation is often anemia.
Hematochezia (fresh blood in the stool) often
caused by left-sided CRC than right-sided CRC.
Right-sided lesions are more likely to cause
diarrhea, while left-sided tumors usually
26. DIAGNOSTIC EVALUATION
Medical history or physical examination
Complete blood count
Fecal occult blood
Sigmoidoscopy or colonoscopy
Biopsy.
Chest X-ray
Ultrasonic examination, CT scan, MRI
Carcino embryonic antigen levels
28. CHEMOTHERAPY
• Use of drugs helps to destroy the cancer
cells.
• Used before surgery to shrink a large
cancer, so that it is easier to remove.
• Given after surgery to eliminate any
remaining cancer cells.
• 5-Fluorouracil (5-FU) with levamisole is
recommended as standard therapy for
specific stages of disease, e.g. stage III to
29. • Capecitabine, a form of 5-FU.
• After surgery, chemotherapy is used to
control symptoms of metastasis and
reduce metastatic spread.
• Intra hepatic arterial chemotherapy, often
with 5-FU may be administered to patient
with liver metastasis.
• Chemotherapy also used to relieve
symptoms of colorectal cancer which
cannot be removed with surgery.
30. TARGETED THERAPIES
•Bevacizumab (Avastin): Treat advanced
colorectal cancer. It is given with
chemotherapy.
•Regorafenib: Treat patient with metastatic
colorectal cancer who has already received
certain types of chemotherapy.
•Epidermal growth factor: Receptor
inhibitors, such as cetuximab and
panitumumab. Recommended for stopping
31. IMMUNOTHERAPY
Immunotherapy is also known as biologic
therapy. A drug which uses immune system
to fight cancer is known as immunotherapy.
•Pembrolizumab: It is prescribed to treat
metastatic colorectal cancer.
•Nivolumab: It is used to treat patients
who are 12 or older and have MSI-H or
dMMR metastatic colorectal cancer.
32. RADIATION THERAPY
•Preoperative radiation may be administered
to patient who has large colorectal cancer.
•Aids in certain more definite tumor margins,
which facilitates resection of the tumor
during surgery.
•Uses X-rays and protons which kills the
cancer cells.
•Used to shrink the large cancer cells before
surgery.
33. SURGICAL THERAPY
Goals of surgical therapy include:
•Complete resection of the tumor
•A thorough exploration of the abdomen to
determine if cancer has spread
•Removing all lymph nodes that drain the area
where the cancer is located
•Restoring bowel continuity so that normal
bowel function return
•Preventing surgical complications.
34. Laparoscopic Surgery
•Some patients able to have laparoscopic
surgery.
•It allows surgeon to carry out surgery
through four or five small cuts in patient's
abdomen while a patient is under anesthesia.
•A telescope camera is inserted into one,
through these cuts. It shows an enlarged
image of an internal abdominal organ on a
screen.
•For removal of cancer, laparoscopic surgery is
35. Colostomy
A colostomy is a
surgical procedure
that brings one end
of the large intestine
out through the
abdominal wall. It
may be temporary
or permanent.
36. Indications of Colostomy
• Cancer of colon/rectum.
• Intestinal obstruction.
• Diverticular disease.
• Hirschsprung's disease (a condition affects
the large intestine and causes problem
with passing stools)
• Crohn's disease.
• Ulcerative disease.
• Trauma to abdomen.
37. Types of Colostomy
Based on duration • Temporary colostomy
• Permanent colostomy
Based on
anatomical
location
• Ascending colostomy
• Transverse colostomy
• Descending colostomy
• Sigmoid colostomy
Based on
construction of
• End Stoma
38. According to Duration
1.Temporary colostomy: Made to allow colon
to rest and heal for a period of time. Kept for
weeks, months or years. Once, definitive
surgery is done, temporary colostomy is
closed and bowel movements will return to
normal.
2.Permanent colostomy: A part of colon is
removed cannot be used again. Acc.
disease/abnormality of intestine, stoma is
39. According to Anatomic Location
1.Ascending colostomy: Made on right side of
abdomen. Fecal matter - liquid form.
2.Transverse colostomy: Located in upper
abdomen towards middle or right side. Fecal
content-loose/soft.
3.Descending colostomy: Present on lower left
side of abdomen. Fecal content - firm and drain
4.Sigmoid colostomy: Made in sigmoid colon, few
inches lower than descending colostomy. Fecal
matter - normal stool. Frequency of fecal
41. According to Construction of Stoma
1. End stoma: When the proximal end of the
bowel is brought to the outside of abdominal
wall. If an abdominal perineal resection is done,
the rectum is removed and the proximal sigmoid
or descending colon is brought out as a stoma.
2. Loop stoma: A loop of bowel, usually the
transverse colon, is pulled outside the abdominal
wall and a bridge is slipped under the loop to
hold it in place. An incisional slit is made on the
top of the exposed colon to allow stool to exit
42. 3. Double-barrel stoma: Bowel is
completely dissected and both ends of
the colon are brought to the outside of
abdominal wall to form two separate
stomas. The proximal stoma is the
functioning stoma that expels stool. A
double-barrel stoma is often
temporary, allowing the bowel to rest
during healing after trauma or surgery
44. • A common temporary colostomy procedure.
• Often performed when a temporary colostomy is
required.
• Performed in an emergency situation for disease of
sigmoid colon or rectum including cancer
diverticulitis.
• Bowel is fused from its attachment within the
abdominal cavity.
• Bowel is then cut and diseased segment is
removed.
• Colon brought out through the abdominal wall and
stitched to the skin as colostomy.
45. COMPLICATIONS
•Bowel perforation with resultant peritonitis,
•Abscess formation.
•Fistula formation to the urinary bladder or
the vagina
•Bleeding
•Obstruction
46. Type of feces according to site of colostomy
Location of stoma Type of effluent
Ileostomy Liquid to mushy
Cecostomy, ascending
colostomy
Liquid to mushy, foul
odor
Right transverse
colostomy
Mushy to semi
formed
Left transverse Semi formed soft
47. NURSING MANAGEMENT
•Educate patient & family members about
colorectal cancer.
•Assess location of stoma & type of
colostomy performed.
•Teach about surgical procedures to patient
and significant others.
•A nurse ensures patient has adequately
prepared for abdominal surgery and general
anesthesia.
•Effects of chemotherapy and radiation
48. •Position collection bag and drainable pouch
over the stoma.
•Empty drainable pouch or replace the
colostomy as needed.
•A nurse should frequently check the pouch
system for proper fit and any signs of
leakage.
•Administer chemotherapeutic agents.
•Relieve stress and anxiety.
•Administer IV fluids, TPN if orally not
50. Colostomy Care
Whether temporary or permanent, a
colostomy can be very distressing to the
patient. Patients with colostomies require
encouragement, understanding and
assistance in overcoming the negative
emotions associated with a colostomy and in
learning independence and self sufficiency in
living with a colostomy.
51. Assessment
1. Stoma color.
2. Size and shape.

Remove and discard gloves.
Document the procedure in the patient's
record. Report and record:
63. Colostomy Irrigation
Irrigation should be done at the same
time each day in order to establish
regularity of bowel evacuation. Unless
contraindicated or otherwise ordered by
the physician, it is best to establish a
routine of daily irrigation in accordance
with the patient's former bowel habits..
64. Articles Required
a. Irrigation kit (irrigation bag with clamp and
tubing, cone tip irrigation catheter, irrigation
drain pouch).
b.Water soluble lubricant.
c. IV pole (or other suspending hook).
d.Soap and water.
e. Washcloth and towel.
f. Ostomy appliance.
g.Waste receptacle.
h.Prescribed irrigating solution, usually 500-1000
ml warm (100-105°F) tap water.
65. •Review the procedure with the patient, if
necessary.
•Wash hands and don gloves.
•Provide privacy to patient.
•If the patient is ambulatory, have the patient
sit on the toilet or on a chair facing the toilet.
If the patient is bedridden, elevate the head
of the bed 45-90° and position rubber sheet
around the patient.
•Fill the irrigation bag with the prescribed
66. •The bottom of the bag should be at the
patient's shoulder level when he/she is seated
to prevent fluid from entering the bowel too
rapidly.
•The bottom of the bag should be placed 18 to
20 inches above the stoma when the patient
is in bed.
•Open the clamp on the irrigation tubing and
allow the solution to fill the tubing. Reclamp
(This prevents the administration of air into
67. •Remove the Ostomy pouch, if applicable and
place the irrigation drain pouch over the
stoma. (Attach stoma belt, if required).
•Place the bottom, open end of the irrigation
drain pouch in the toilet (or bedpan) to
facilitate drainage by gravity.
•Connect the cone tip catheter to the tubing
and flush with solution.
•Lubricate the cone with the water soluble
lubricant to avoid irritating the mucous
68. •Lubricate the cone with the water soluble
lubricant to avoid irritating the mucous
membranes.
•Gently insert the cone into the stoma, so that
the stoma is occluded.
•Unclamp the irrigating tubing and allow the
water to flow in slowly.
•Allow water to enter the colon over a period
of 10 to 15 minutes.
69. •If cramping occurs, slow down the flow rate
and ask patient to deep breathe until cramps
subside. Cramping during irrigation may
indicate that:
i. The bowel is ready to empty.
ii. The water is too cold.
iii. The flow is too fast.
iv. The tube contains air.
•Clamp the catheter and remove from the
stoma. Fold down the top opening of the
70. toilet for about 15 to 20 minutes so the initial
colostomy re- turns can drain into the toilet. (If
the patient is on bed rest, allow the colostomy to
drain into the bedpan).
•Close the colostomy irrigation drain pouch with
a rubber band or pouch clip, then ambulate the
patient or return him/her to bed.
a.Ambulating stimulates elimination, producing
improved irrigation return.
b.Have the non-ambulatory patient lean
forward or massage his/her abdomen to
71. •Wait approximately 1 hour for the rest of the
colostomy return, then remove the irrigation
drain pouch from the patient.
•Gently clean the area around the stoma with
mild soap and water.
•Be careful not to rub the skin.
•Rinse and dry the area with a towel.
•Apply a clean pouch or dressing, as applicable.
•Provide for the patient's comfort.
•Remove and dispose off used supplies.
72. •Record the procedure and significant nursing
observations in the patient's clinical record and
report it to incharge nurse.
a.Note color and condition of stoma and
peristomal skin.
b.Record color, consistency and amount of
drainage.
c. Note amount of irrigating solution used.
•As recovery progresses, the nursing personnel
should gradually assume a more passive role in
colostomy care, allowing the patient to assume
75. Nursing Diagnosis
•Acute pain related to surgical intervention.
•Risk for impaired skin integrity related to
fecal drainage and pouch adhesive.
•Imbalanced nutrition: Less than body
requirements related to decreased
appetite.
•Fear or anxiety related to knowledge
deficit.
•Disturbed body image related to
colostomy.
76. CONCLUSION
Patients have more treatment choices today.
Early detection increases the chance of cure.
The evolving colorectal cancer treatments
improve the survival in colorectal cancer
patients. Biomarker can predict the patient's
response to targeted therapies. Future
studies to explore more predictive
biomarkers in the cancer treatment to
identify the right patient to receive tailored
targeted therapy.
