2 MALIGNANT WOUNDS Connie Sarvis RN, BN, MN, CON(C), IIWCC, CWS Skin and Wound Consultant Seven Oaks General Hospital

3 Malignant Wound? Fungating Wound? Cutaneous Malignancy? Malignant Cutaneous Ulcer? Tumor Necrosis?

4 How Common Are They? 5-10% of patients with metastatic cancer will develop a malignant wound! Wound Care Designed to afford Relief without Cure

5 Most Common Sites Breast Head/Neck Back/Trunk/Abdomen Groin/Axilla Genital

6 How do they develop?

7 From a Primary Skin cancer left untreated. Ie. Basal cell ca Squamous cell ca

8

9

10 A Primary Tumor invading up into and through the skin. Ie. Breast tumor

11

12 Tumor has invaded blood or lymph vessels – small skin capillaries trap malignant cells

13

14

15 During Surgery – seeding of malignant cells in the dermis occurs

16

17

18

19 Conversion: Malignant wound develops in another chronic ulcer/scar tissue

20

21 PATHOPHYSIOLOGY! Starts as discrete, non tender nodules Can be skin tone, pink, red, violet, blue, black or brown! As malignant cells grow and divide, the nodules enlarge – interfere with skin capillaries and lymph vessels

22 Tumor very disorganized! – poor skin perfusion, edema and necrosis occurs Tumors often extend into deeper structures – sinus and fistula formation

23 TREATMENT

24 SURGERY Used occasionally to reduce tumor mass but may not always be possible due to bleeding, infection, etc.

25 Chemotherapy Can decrease tumor mass Depends on tumor response

26 RADIOTHERAPY Can reduce the size of mass – controlling exudate, bleeding and pain Adding radiotherapy reactions to wound

30 ASSESSMENT Location of Wound Size, Depth and Shape Amount and Nature of Exudate Presence and Level of Malodor Type of Tissue Present Signs and Symptoms of Infection Nature and Type of Pain Condition of Peri-wound Bleeding

31 ASSOCIATED PROBLEMS WHAT DOES THE PATIENT THINK IS THE MOST IMPORTANT?

32 ODOR!! Anaerobic Bacteria infecting or colonizing necrotic tissue-Putrescine, Cadaverine Klebsiella, Pseudomonas & Proteus Necrotic Tissue Odor Stale Exudate

33 Presence of Infection Tissue Degradation Anaerobic Bacterial Colonization Tissue Necrosis Malodor

34 Debridement Remove necrotic tissue where bacteria are Sharp? Mechanical? Autolytic?

35

36 SYSTEMIC ANTIBIOTICS Control Odor from Bacterias Metabolic End Products Bacterial Resistance Adverse Effects

37 FLAGYL ( Metronidazole) gel -.75% -displacement tablets crushed in gel oral tablets (200-500 mg. TID) IV/irrigation Anaerobes only – Binds their DNA

38 SILVER/IODOSORB Reaches the Gram positive cocci and gram negative rods – Pseudomonas No bacterial resistance Longer to control odor

39

40 CHARCOAL DRESSINGS Absorbs volatile malodorous chemicals from wound before they pass into air Needs to be an airtight seal

41 Pouching? Increase Frequency of Drsg. Changes Room Sprays – Nausea!! Mentholatum applied to Nostrils Kitty Litter, Charcoal, Baking Soda, Vinegar Distraction Techniques

42

43 Tumor Cells can secrete Vascular Permeability Factor – vessels become more permeable to plasma colloids and fibrinogen Inflammatory reaction - Histamines

44 Amber Exudate Cloudy Purulent Sanguinous Hemo- purulent Serous

45 THE 5 CS OF EXUDATE MANAGEMENT CAUSE CONTROL COMPONENTS CONTAINMENT COMPLICATIONS

46 CAUSE Lymphedema Infection Drug-related Decreased se albumin Heart Failure

47 CONTROL Is systemic and or local control possible?

48 COMPONENTS VISCOSITY? BACTERIA? NECROTIC MATERIAL?

49 CONTAINMENT Collection Devices Capillary Action Dressings VAC Absorptive Dressings Bacterial Control Dressings

50 COMPLICATIONS

51

52 Very fragile, friable tissue!!! Spontaneous bleeding if tumor erodes into a blood vessel – profuse Bleeding can be compounded by decreased platelet function Infection?

53

54 PREVENT TRAUMA!! Paraffin/tulle? Gauze? Telfa? Silicone?

55 Control Bleeding Alginates Silver Nitrate Gel Foams Fibrinolytic Inhibitors Topical Adrenaline Sucralfate

56 PRESSURE? OR ICE?

57 Tumor pressing on nerve endings During dressing changes Exposure of Dermis to air

58 PAIN Avoid Trauma Gentle Cleansing- without gauze No cold irrigations No H 2 O 2, Iodine, Chlorhexidine, Eusol!! Morphine gel (1 mg./1 ml hydrogel or metronidazole gel)

59 Excoriation Pruritis

60 EXCORIATION Barriers – No Sting Hydrocolloid Frames Zinc Oxide Avoid Tape – Netting/garments Pouching Diaper Technology

61

62 PRURITIS Antihistamines? Cool Hydrogel Sheets Menthol Cream TENS? Avoid vasodilation!! Moisturizers (Avoid Lanolin)
