  • INCIDENCE• According to the National Cancer Institute (NCI, 2008), approximately 760,000 cases of stomach cancer are diagnosed worldwide.• New cases: 21,000 in United States (NCI, 2010); 13,000 men and 8,000 women Created by: Katherine L. Laud, SN
  • INCIDENCE• In Philippines, cancer of the stomach is the 8th leading site of cancer overall. According to Department of Health (DOH), it is 6th among males and 10th among females Created by: Katherine L. Laud, SN
  • INCIDENCE• New cases: 2,563 in Philippines; 1,511 among males and 1,052 among females (DOH, 1998) Created by: Katherine L. Laud, SN
  • INCIDENCE• Most (85%) cases of gastric cancer are adenocarcinomas that occur in the lining of the stomach (mucosa). Approximately 40% of cases develop in the lower part of the stomach (pylorus); 40% develop in the middle part (body); and 15% develop in the upper part (cardia). In about 10% of cases, cancer develops in more than one part of by: Katherine L. Laud, SN Created the organ.

  • MORTALITY• Stomach cancer is the second leading cause of cancer death worldwide (737, 000 deaths, 10% of the total). The highest mortality rates are in Eastern Asia and the lowest in Northern America (World Cancer Research Fund International, 2008).• Deaths: 10,570 in United States (NCI, 2010)• Deaths: 1,484 in Philippines (DOH, 1998) Created by: Katherine L. Laud, SN

  • ETIOLOGY/RISK FACTORS• Family history of gastric cancer• Helicobacter pylori infection (a common bacteria that can also cause stomach ulcers)• History of an adenomatous gastric polyp larger than 2 centimeters• Common in men• Smoking Created by: Katherine L. Laud, SN
  • ETIOLOGY/RISK FACTORS• Risk increases after age 50• History of chronic atrophic gastritis• Previous stomach injury• History of pernicious anemia• Evidence suggest that gastric cancer may be linked to diet, such as salty food, smoked fish, preserved meats, and low in fresh fruits and vegetables. Created by: Katherine L. Laud, SN
  • ETIOLOGY/RISK FACTORS• Some studies have found that a diet high in red meat is another possible risk factor. Eating red meat an average of about twice a day seems to raise the risk of stomach cancer. This risk is increased even more if the meat is barbecued and well done.• Workers in the coal, metal, and rubber industries Created by: Katherine L. Laud, SN

  • PREVENTION, SCREENING, DETECTION• Changing lifestyle or eating habits (balanced diet)• Avoiding things known to cause cancer• Taking medicines to treat a precancerous condition or to keep cancer from starting Created by: Katherine L. Laud, SN
  • PREVENTION, SCREENING, DETECTION• There is no standard or routine screening test for stomach cancer. However, upper endoscopy has been studied as a screening test to find stomach cancer at an early stage. Created by: Katherine L. Laud, SN
  • PREVENTION, SCREENING, DETECTION• Scans - these may include ultrasound, MRI or CT scans• Complete blood count (CBC) to check for anemia• Esophagogastroduodenoscopy (EGD) with biopsy• Stool test to check for blood in the stools Created by: Katherine L. Laud, SN
  • Created by: Katherine L. Laud, SN
  • CLASSIFICATION• T Stage for Gastric Cancer - Tis (Carcinoma in situ), T1, T2, T3, T4• N Stage of Gastric Cancer - N0, N1, N2, N3• M Stage for Gastric Cancer - M0, M1 Created by: Katherine L. Laud, SN
  • Created by: Katherine L. Laud, SN
  • CLINICAL FEATURES• Weight loss and persistent abdominal pain, Dysphagia• Feeling bloated after eating only a small meal• Nausea and vomiting, Hematemesis• Melena Created by: Katherine L. Laud, SN
  • Created by: Katherine L. Laud, SN
  • DIAGNOSIS AND STAGING• Thorough history and physical examination• MRI, CT Scan, Upper Endoscopy• Biopsies Created by: Katherine L. Laud, SN
  • DIAGNOSIS AND STAGING*STAGING• Stage 0: Tis, N0, M0• Stage IA: T1, N0, M0• Stage IB: Any of the ff: T1,N1,M0; T2,N0,M0• Stage IIA: Any of the ff: T1,N2,M0; T2,N1,M0; T3,N0,M0• Stage IIB: Any of the ff: T1,N3,M0; T2,N2,M0; T3,N1 SN T4a,N0,M0 Created by: Katherine L. Laud, M0;

  • METASTASIS• Stomach cancer usually begins in cells in the inner layer of the stomach. Over time, the cancer may invade more deeply into the stomach wall. A stomach tumor can grow through the stomachs outer layer into nearby organs, such as the liver, pancreas, esophagus, or intestine. Created by: Katherine L. Laud, SN
  • METASTASIS• Stomach cancer cells can spread by breaking away from the original tumor. They enter blood vessels or lymph vessels, which branch into all the tissues of the body. The cancer cells may be found in lymph nodes near the stomach. The cancer cells may attach to other tissues and grow to form new tumors that may damage those tissues. by: Katherine L.

  • SURVIVAL The overall 5-year relative survival rate ofStage IA 71% people with stomachStage IB 57% cancer in the United States is about 28%. OneStage IIA 45% reason for this is thatStage IIB 33% most stomach cancersStage IIIA 20% are found at an advancedStage IIIB 14% stage. The outlook for survival is better if theStage IIIC 9% cancer is in the lower partStage IV 4% of the stomach than if it is*The survival rates above come from theNational Cancer Institutes SEER database. in the upper partThey are based on people diagnosed with (American Cancerstomach cancer and treated with surgery Created by: Katherine L.
