37. OBJECTIVES :
CONT…
• TO EXPLAIN THE ANATOMY OF STOMACH.
• TO DESCRIBE ABOUT HISTOPATHOLOGY AND BLOOD SUPPLY
• TO CLASSIFY GASTRIC CA.
• TO EXPLAIN REGARDING TNM STAGING.
• TO DISCUSS SIGN & SYMPTOMS.
• HOW TO INVESTIGATE AND MANAGE GASTRIC CA

38. ANATOMY:
The stomach J-shaped. The stomach has two surfaces (the anterior & posterior), two curvatures (the greater &
lesser), two orifices (the cardia & pylorus). It has fundus, body and pyloric antrum.
The stomach begins at the gastroesophageal junction and ends at the duodenum. The stomach has 3 parts. The
uppermost part of the stomach is the cardia, and the largest and middle part is called the body. The distal portion of
the stomach, the pylorus, connects to the duodenum.
These anatomic zones have distinct histologic features. The cardia contains predominantly mucin-secreting cells.
The fundus (ie, body) contains mucoid cells, chief cells, and parietal cells, while the pylorus is composed of mucus-
producing cells and endocrine cells.
. Approximately 40% of cancers develop in the lower part, 40% in the middle part, and 15% in the upper
part, and 10% involve more than one part of the organ

39. BLOOD SUPPLY:ARTERIAL SUPPLY
a. The left gastric artery
b. Right gastric artery
c. Right gastro-epiploic artery
d. Left gastro-epiploic artery
e. Short gastric arteries
The corresponding veins drain into portal system.
The lymphatic drainage of the stomach corresponding
its blood supply.

47. TYPES OF GASTRIC TUMORS

49. PATHOLOGY OF GASTRIC (MALIGNANT)
TUMOURS:
 The gastric cancer may arise in the antrum
(50%), the gastric body (30%), the fundus or
oesophago-gastric juntion (20%).

50. PATHOLOGIC CLASSIFICATIONS
Borrmann’s Gross Morphology
Lauren’s Histopathology (cohesiveness)
WHO Histopathology (grade and growth)
Ming Histopathology (growth and pattern)
Goeski Histhopathology (atypia & mucin)

51.  Early Gastric Cancer:
Defined as cancer which is confined to the mucosa and
submucosa regard- less of lymph nodes status.
 Advanced Gastric Cancer:
Defined as tumor that has involved the muscularis propria of
the stomach wall.

52. Early Gastric Cancer
The term 'early gastric cancer' is used to describe
tumours confined to the gastric mucosa and submucosa,
irrespective of nodal status, and was elaborated in 1962
by the Japanese Society of Gastroenterological
Endoscopy
Type I Exophytic lesion extending into the gastric lumen
Type II Superficial variant
II A Elevated lesions with a height no more than the
thickness of the adjacent mucosa
II B Flat lesions
II C Depressed lesions with an eroded but not
deeply ulcerated appearance
Type III Excavated lesions that may extend into the
muscularis propria without invasion of this layer by actual
cancer cells

invade the adjacent structures with lymphatic & haematogenous metastasis.
 Advanced gastric cancer classified according to the Bormann's morphologic description as –
 Borrmann I: Fungating
 Borrmann II: Carcimatous ulcer without infiltrating surrounding

58. EVALUATION OF GASTRIC CANCER:
 History
 Clinical Examination
 Investigations
 The clinical features of gastric cancer may arise
from local disease, its complications or its
metastases.

59. CLINICAL FEATURES
 SYMPTOMS
 CLASSICAL HUNGER PAIN
 DISTENSION OF UPPER ABDOMEN WITH EPIGASTRIC FULLNESS
 VOMITTING
Projectile
Nature: Solids, then liquids
Type: Bile stained or not
Timing: Usually within an hour of a meal
1. Often asymmtomatic until late
stage
2. Weight loss due to anorexia and
early satiety is the most common
symptoms
3. Chronic occult blood loss is
common;
GIT bleeding (5%)
5. Dysphagia (cardia involvement)
6. Cachexia

60.  SIGNS
 Look at the patient!
 Dehydrated
 Cachecxic
 Basic observations
 Tachycardia
 Examination
 Often unremarkable
 VISIBLE GASTRIC PERISTALSIS
(Stomach that you Feel)
 SUCCESSION SLASH
(Stomach that you hear)

61. Clinical Manifestation:
6. Paraneoplastic syndromes ( Trousseau’s syndrome –
thrombophlebitis; acanthosis nigricans – hyperpigmentation
of axilla and groin; peripheral neuropathy)
7. Signs of distant metastasis:
a. Hepatosplenomegally with ascites& jaundice
b. Krukenbergs tumor(enlarged ovaries on p/E
c. Blummers shelf i.e fullness in the pelvis cul –de- sac ( drop
metastasis)
d. Virchow’s node (enlarged supraclavicular nodes)
e. Sister Joseph node i.e infilteration of umblicus.(pathognomonic
of advances dse)

62. SPREAD OF GASTRIC CANCER:
 The diffuse type spreads rapidly through the submucosal and
serosal lymphatic and penetrates the gastric wall at early stage
 the intestinal variety remains localized for a while and has
less tendency to disseminate.
The spread by:
1. Direct (loco regional)
2. Lymphatic
3. Blood (Haematogenous)
4. Transcoelomic

63. Lab Studies
The goal of obtaining laboratory studies is to assist in determining optimal therapy.
A complete blood cell count
can identify anemia, which may be caused by bleeding, liver dysfunction,
or poor nutrition. Approximately 30% of patients have anemia.
Electrolyte panels and liver function tests
also are essential to better characterize the patient's clinical state.
Carcinoembryonic antigen (CEA)
is increased in 45-50% of cases.
Cancer antigen (CA) 19-9
is elevated in about 20%of cases.
63

64. INVESTIGATIONS:
A. Upper gastero intestinal endoscopy
with multiple biopsy and brush
cytology
B. Radiology:
 CT Scan of the chest and abdomen
 USS upper abdomen
 Barium meal
C. Diagnostic laparoscopy
•Inspect peritoneal surfaces, liver surface.
•Identification of advanced disease avoids
non-therapeutic laparotomy in 25%.
•Patients with small volume metastases in
peritoneum or liver have a life expectancy
of 3-9 months, thus rarely benefit from
palliative resection.

65. 1.UGIS (double contrast)
2.Endoscopy (Biopsy / Ultrasound)
 GOLD STANDARD
 Best pre-operative staging
 Needle aspiration of LN w/ ultrasound guidance
 Can even give preop neoadjuvant tx
3.CT scan (intravenous and oral contrast):
 For pre-operative staging
4.Whole body Positron Emission Tomography scanning (PET):
 Tumor cell preferentially accumulate positron-emitting 18F
fluorodeoxyglucose.
5.Laparoscopy
Investigations for patients with gastric cancer

66. SCREENING OF GASTRIC CANCER
 Patients at risk for gastric CA should undergo yearly
endoscopy and biopsy:
1. Familial adenomatous polyposis
2. Hereditary nonpolyposis colorectal cancer
3. Gastric adenomas
4. Menetrier’s disease
5. Intestinal metaplasia or dysplasia
6. Remote gastrectomy or gastrojejunostomy

67. GOAL OF TREATMENT
 Optimize the patient
 Resection of all tumor
 All margins (proximal, distal, and radial) should be negative
and an adequate lymphadenectomy performed
 Negative margin of at least 5 cm
 PosTop care of patient nutritonal &
dietery status.

68. STEP OF MANAGEMENT:
 1. extent of surgical resection
 A. proximal tumour
 B mid body tumour
 C distal tumour
 Endoscopic treatment
 EMR (endoscopic mucosal resection)
 Ablation
 Laproscopic gastric resection
 2.extent of lymphadenectomy
 3. adjuvant therapy
 Adjuvant combined modality therapy
 Neoadjuvant therapy chemotherapy
 4. palliative therapy
The extent of gastric
resection depends on:
- Tumor size
- location
- Depth of invasion
- Histological type

69. ENDOSCOPIC RESECTION OF GASTRIC CARCINOMA
Criteria:
1. Tumor < 2cm in size
2. Node negative
3. Tumor confined on the mucosa
Nodes metastasis is < 1%:
1. No mucosal ulceration
2. No lymphatic invasions
3. <3cm tumor

70. TREATMENT:
SURGERY:
Radical subtotal gastrectomy
 Standard operation for gastric cancer
Organs resected:
1. Distal 75% of stomach
2. 2 cm of duodenum
3. Greater & lesser omentum
4. Ligation of R & L gastric artery and
gastroepiploic vesels
5. Billroth II gastojejunostomy

71. TREATMENTS OF GASTRIC CANCER:
 Surgery (Early or Advanced Cancer)
 Proximal tumours which involve the fundus, cardia or body (total
gasterectomy)

72. DISTAL TUMOURS WHICH INVOLVE THE LOWER ½ (SUB-
TOTAL OR PARTIAL GASTERECTOMY).

73. THE RESIDUAL TUMOR (R) CLASSIFICATION
The absence or presence of demonstrable residual tumor after
conclusion of the treatment (UICC)
R0 resection -no demonstrable residual tumor
R1 resection- microscopically demonstrable
residual tumor (e.g. diseased residual margin)
R2 resection – macroscopically visible tumor
Distinction between primary palliative intervention
(R1&R2) vs. potentially curative ones (R0)

Surgical Treatment-contd.
The main controversy relates to the extent of lymph node dissection. Types of resective surgery have been
classified based on this criterion as follows:
1. R1: complete removal of perigastric lymph nodes;
2. R2: resection of perigastric nodes and those along the left gastric, splenic, and right hepatic
arteries;
3. R3: R2 with dissection of celiac axis nodes;
4. R4: R3 with dissection of paraaortic nodes.
Five-Year Survival Rate of Patients with Stomach Cancer
Tumor stage % Survival
R1 resection R2 resection
IA 88 91
IB 56 85
II 39 58
IIIA 7 30
IIIB 0 12

76. WHAT IS THE IDEAL EXTENT OF LYMPHADENECTOMY ?
D0- removes less than all relevant N1 nodes
D1- removes N1 nodes only
- Lt and Rt cardiac
- Lt and Rt gastro-epiploic
- Sub and Supra pyloric
D2- removes all N1 and N2 nodes
- Lt gastric
- Common hepatic
- Celiac
- Splenic hilum and along splenic artery
D3- removes all N2 and N3 nodes

77. EXTENT OF LYMPHADENECTOMY
 The Japanese Research Society for Gastric Cancer numbered the lymph node
stations that potentially drain the stomach
Generally these are grouped into
 level D1 ( stations 3 to 6),
 level D2 ( stations 1, 2, 7, 8, and 11) &
 level D3 ( stations 9, 10, and 12) nodes
 D1 nodes are perigastric
 D2 nodes are along the hepatic and splenic arteries
 D3 nodes are the most distant

78. LYMPHADENECTOMY
The extent of resection is described as
 D1. Limited Lymphadenectomy. All N1
Nodes removed en bloc with the stomach
 D2. Systematic Lymphadenectomy. N1 &
N2 nodes en bloc with stomach
 D3. Extended Lymphadenectomy. A more
radical en bloc resection including N3
nodes

79. POST OP COMPLICATIONS
Early complications
 Paralytic ileus.
 Leakage from suture line.
 Leakage from duodenal stump.
 Acute Cholycystitis, Pancreatitis
 Stomal obstruction.
Late complications
• Early Dumping syndrome
• Late dumping syndrome.
• Bilious vomiting.
• Gastric stump cancer
• Vit B12 deficiency
• Osteoporosis

80. NEO ADJUVANT CHEMOTHERAPY
 Downstaging of disease to increase resectability,
 Decrease micrometastatic disease burden prior to surgery
 Allow patient tolerability prior to surgery
 Determine chemotherapy sensitivity
 Reduce the rate of local and distant recurrences, and ultimately
improve survival.

81. CHEMOTHERAPY
 Chemotherapy for gastric
cancer
(Pre-operatve & post-
operative)
 The most widely used regimen is
5-FU, doxorubicin, and
mitomycin-c. The addition of
leukovorin did not increase
response rates.
 Radiotherapy
(Pre-intra & post-
operatively)
 Radiotherapy- studies show
improved survival, lower rates of
local recurrence when compared to
surgery alone.
 In unresectable patients, higher 4
year survival with mutimodal tx, in
comparison to chemo alone.
RADIOTHERAPY

82. PALLIATIVE CARE
 Radiotherapy provides relief from bleeding, obstruction, and pain
in 50-75%
 Median duration of palliation is 4-18 months.
 Advanced Unresectable Disease
 Surgery is for palliation, pain, allowing oral intake
 Wide local excision, partial gastrectomy, total gastrectomy, simple
laparotomy, gastrointestinal anastomosis, and bypass for food intake or
pain relief

83. RESULTS OF THERAPY – STOMACH CANCER
 Surgery with curative intent
 42% of patients
 5 year survival – 60%
 Node positive - 35%
 Node negative - 88%

84. SUMMARY

85. HAVE WE MET OUR OBJECTIVES?
