4. Present Illness (I) 25 y/o married female Vomiting and abdominal pain since 1998 Mesenteric fibromatosis was diagnosed at CGMH Two times of debulking surgery and bowel resection on 1998 and 2000/7 Short bowel (80cm) and residual tumor were noted

5. Present Illness (II) Admitted to GS ward due to post-prandial vomiting on 2000/8 Admitted to Urology due to obstructive uropathy on 2000/9

Physical examination Height: 173.5cm Weight 36 Kg T/P/R: 36.2/70/19 BP: 120/80 General appearance: thin and tall Conscious: clear Conj: not pale, sclera: not icteric no oral / buccal pigmentation Chest: Clear BS, RHB without murmur Abd: tenderness (-), BS: hyperactive palpable mass over RLQ/hypogastric area, oval shape, 10x 5cm, hard nature, non-movable Ext: no edema, no pigmentation

9. Polyposis of stomach Fundic gland polyp

10. Tentative diagnosis Polyposis of stomach and duodenum Mesentary fibromatosis  Consider Familial polyposis coli plus soft tissue tumor  Gardner’s syndrome

11. Familial adenomatous polyposis with associated syndrome

12. Gardner’s syndrome Familial polyposis coli Combined with osteoma and soft tissue tumor  Gardner’s syndrome Combined with Brain tumor  Turcot’s syndrome

13. Polyposis of colon Tubular adenoma

14. Abdominal CT

15. Osteoma

16. Odontoma

17. Mesenteric fibromatosis

18. Diagnosis Gardner’s syndrome with manifestations of a. Polyposis of stomach, duodenum and colon b. mesentery fibromatosis s/p debulking surgery with residual tumor and bilateral hydronephrosis, total GI obstruction and short bowel syndrome c. Osteoma/odontoma of maxillary, frontal bone and mandible

19. Admission course Total parenteral nutrition due to total GI obstruction COX-2 NSAID ( Celebrex ) for familial polyposis coli Consider C/T with doxorubicin and DITC regimen Recurrent OSSA sepsis

20. Further plan Medical management for fibromatosis Home total parenteral nutrition Mental support Family screening

21. Discussion Polyposis of GI tract Current management of FAP Gardner’s syndrome Current management of fibromatosis

22. Classification of polyps Non-neoplastic polyp –Hyperplastic polyp –Juvenile polyp –Inflammatory polyp –Lymphoid polyp Neoplastic polyp –Benign Tubular adenoma Tubulovillous adenoma Villous adenoma –Malignant Carcinoma in situ Intramucosal carcinoma Invasive carcinoma

23. Classification of polyposis syndrome Inherited adenomatous polyposis syndrome –Classic FAP –Gardner’s variant –Turcot’s variant Non-familial multiple polyposis syndrome –Cronkhite-Canada syndrome –Lymphoid polyposis Familial hamartomatous polyposis syndrome –Peutz-Jeghers syndrome –Juvenile polyposis

24. Familial adenomatous polyposis with associated syndrome

25. Familial adenomatous polyposis Chromosome 5q, APC gene Autosomal dominant Progressive development of hundreds to thousands of adenomatous polyps in colon Inevitable to became colon cancer – Onset: 25 y/o cancer: 39 y/o – Symptom: 33 y/o death: 42 y/o – Diagnosis: 36 y/o 90% identified: 50 y/o

26. Familial adenomatous polyposis Surgery –Timing –Extent of surgery ( total proctocolectomy vs. subtotal colectomy ) Medical management –COX-2 NSAID

27. Celecoxib vs. FAP N Eng J Med 2000 342 1946-1952 Double-blind, placebo controlled Three arm –Celecoxib 100mg bid for 6 months –Celecoxib 400mg bid –Placebo Colonscopy at beginning and end Results placebo(15) 100mg(32) 400mg (30) Beginning 15.5+-13.4 11.5+-8.5 12.3+-8.2 End(number/size) 4.5%/4.9% 11.9%/14.6% 28% /30.7 P valve 0.33/0.09 0.003/0.001

28. Gardner’s Syndrome Familial adenomatous polyposis Extraintestinal manifestation –Bone Osteoma of mandible (90%), skull, and long bones Exostoses Dental abnormalities (supernumerary teeth, impacted teeth) –Congenital hypertrophy of the retinal pigmented epithelium (CHRPE) –Mesenteric fibromatosis (Desmoid tumors)

29. Desmoid tumors Surgery –High recurrent rate (20-80%) Radiotherapy –Total dose of 50-60 Gy –As an adjunct to surgery –Drop recurrent rate to 20-40% ( for abdominal wall or extra-abdominen) –No response / higher recurrence for intra-abdominal lesion

30. Desmoid tumors Medical therapy –NSAID –Tamoxifen / Medroxyprogesterone / LHRH analouge –Interferon, steroid, colchicine…. –Chemotherapy Doxorubicin / Dacarbazine
