Carcinoma stomach management

  1. 1. Carcinoma Stomach ( Gastric Carcinoma ) Management - Shriyans Jain
  2. 2. When do you suspect ? • Clinical Features – Symptoms suggestive of a malignancy ? – Signs ? Differential diagnosis ?
  3. 3. Differentials • Acid peptic disease, pyloric stenosis with gastric outlet obstruction. •Gastritis •Pancreatic mass •Transverse Colon mass
  4. 4. Investigations • Flexible Endoscopy • Contrast radiology • Ultrasonography ( Endoscopic USG – EUS ) • CT Scan and MRI • PET – CT • Laparoscopy
  5. 5. To confirm the diagnosis • Flexible Upper GI Endoscopy with directed biopsy followed by histopathological examination of the sample.
  6. 6. Flexible Upper GI Endoscopy EGD (esophago gastro duodenoscopy) • Visual examination of the upper intestinal tract using a lighted, flexible fiberoptic or video endoscope • Gold standard • More sensitive than conventional radiology ( 95% accuracy ) • Advantages – Outpatient procedure – No radiation Exposure – Targeted biopsy from the lesion can be taken at the same setting. – Diagnosis can be made more accurately
  7. 7. Indications • Ulcers in the upper GI tract • Tumors of the stomach or esophagus • Severe/Persistent Dysphgia • Undiagnosed Upper abdominal pain or indigestion • Intestinal bleeding • Esophagitis and heartburn – unresponsive to medical therapy • Gastritis
  8. 8. Contraindications • Shock • Acute MI • Peritonitis • Acute perforation • Corrosive injuries of Oesophagus
  9. 9. Gastric Carcinoma – Intestinal Type Gastric Carcinoma – Diffuse Type
  10. 10. Contrast Radiology • Single Contrast/ Double Contrast • Barium Meal • Advantages – Sensitivity comparable to endoscopy – Non Invasive procedure
  11. 11. Carcinoma of the gastric antrumStomach – Normal Duble contrast barium study
  12. 12. Gastric Carcinoma of the body and Carcinoma along the greater curvature proximal antrum ( Ulcerative lesion with filling defect ) (Multiple small ulcerations )
  13. 13. Findings in Carcinoma Stomach • Irregular filling defect • Loss of rugosity • Delayed emptying • Dilatation of stomach in carcinoma pylorus • Decreased stomach capacity in linitis plastica • Carmanns meniscus sign
  14. 14. Ultrasonography • Endoscopic / Endoluminal Ultrasound is useful to detect the involvement of layers of the stomach, nodal status and to differentiate early from advanced cancer. • Excellent at determining the T- Stage ( 90% ) • High frequency probes used to differentiate T1-2 stage • Nodal status can also be assessed • Limited use in advanced disease
  15. 15. The white arrow indicates the tumour invasion The black arrow indicares the muscularis propria A – TI stage – Tumour localized to the mucosa and sub mucosa B – T2 stage – Tumour invades the muscularis propria C – T3 stage – Tumour invades subserosa and abuts the surrounding structures ( here Aorta )
  16. 16. Chest X-ray • Look for – Lung metastases – Pleural Effusion USG abdomen • Liver metastases
  17. 17. Computed tomography and MRI • Every patient with a histological diagnosis of gastric Carcinoma should undergo a Ct of the chest and abdomen. • Provides information about – M stage ( Liver, Lung, Peritoneum and distant nodes ) – T4 stage ( involvement of the adjacent structures )
  18. 18. Localized versus Diffuse thickening
  19. 19. Secondaries from Carcinoma Stomach in the Liver and the Lung
  20. 20. Laproscopy • To stage the disease especially in locally advanced tumours – Peritoneal secondaries – Occult metastases – Organ invasion – Peritoneal lavage for cytology – Biopsy of peritoneum and nodes
  21. 21. Signs of inoperability • Peritoneal deposits • Fixity • Liver secondaries • Fixed iliac nodes • Para aortic nodes • Ascitic fluid positivity • Sister Mary Joseph Nodule • Left axillary lymph node secondaries
  22. 22. Other tests • Left Supraclavicular Node biopsy • Tetracycline flourescence test • CA 72-4 in relapse, CEA, CA 19-9, CA 12-5 • Combined PET – CT • Sentinel Node biopsy • HB, Hematocrit, LFT, PT
  23. 23. Treatment
  24. 24. Multidisciplinary Team • Surgery • Chemotherapy • Immunotherapy • Radiotherapy • Oncology and • Palliative Care
  25. 25. Goal of Treatment • 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

  31. 31. Surgical Resection of the tumour • Based on the TNM staging – Patients with early gastric cancer should undergo a subtotal or total D2 gastrectomy – Patients with advanced disease should undergo multi-modality treatment with neoadjuvant chemotherapy and surgery
  32. 32. Based on site of the tumour • Pylorus Lower radical Gastrectomy ( proximal 5cm clearance with removal of greater omentum , lesser omentum, lymph nodes, spleen, tale of pancreas ) • OG junction Upper Radical Gastrectomy ( Total Gastrectomy is ideal ) (removal of greater omentum , lesser omentum, lymph nodes, spleen, tale of pancreas )

  40. 40. Adjuvant Therapy • Rationale behind radiotherapy is to provide additional local-regional tumor control. • Adjuvant chemotherapy is used either as a radiosensitizer or as definitive treatment for presumed systemic metastases.
  41. 41. Adjuvant Radiotherapy • lower rates of local recurrence in patients who received postoperative radiotherapy than in those who underwent surgery alone (British stomach cancer study group) • Improved survival (mayo clinic randomized patients)
  42. 42. Intra operative radiotherapy • allows for a high dose to be given in a single fraction while in the operating room so that other critical structures can be avoided. • Stage 3 and 4 • Median survival (21 months vs 10 months ) with IORT
  43. 43. Adjuvant Chemotherapy • No consistent survival benefit. • Epirubicin . 5 florouracil ,cis platinium (ECF) • Combination of chemoradio therapy has better outcome
  44. 44. 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.
  45. 45. Palliative Care • radiotherapy provides relief from bleeding, obstruction, and pain in 50-75% • wide local excision, partial gastrectomy, total gastrectomy, simple laparotomy, gastrointestinal anastomosis, and bypass for food intake or pain relief
  46. 46. Summary
  47. 47. Prognostic Factors • Early vs advanced • Histological grading • Staging • Gross types • Lymph node status • Liver secondaries • Serosal involvement • Diffuse vs intestinal • Ascites • Response to treatment
