Cancer wounds are also known as malignant subcutaneous wounds, defined as epithelial integrity being destroyed by malignant cells. The wound is not healed or the wound is growing. Invasive skin tissue can lead to loss of skin integrity, loss of function and tumor growth and deformation. The most common manifestations were fungal-like lesions (cauliflower-like) and ulcerative lesions.
(1) Fungal-like lesions: malignant tumors penetrate the epithelium leading to a prominent nodule, accompanied by strange growth, easy bleeding, infection and unpleasant exudate.
(2) Ulcer-like damage: it is a malignant tumor infiltration of the skin to form a depression or cavity, tissue fragile, easy to bleed, susceptible to infection, infiltration fluid, unpleasant smell.
Cancer Wound Care
2. Factors contributing to the formation of cancerous wounds:
(1) Cutaneous local primary melanoma skin cancer;
(2) Skin Local primary phosphorus-like epithelial carcinoma;
(3) Cervical lymphoma; a distant cancer cell with lymphatic blood transferred to infiltrate the skin caused by (lymphoma and sarcoma) lymphoma;
(4) Local organ infiltration (breast cancer);
(5) Chronic wound malignant transformation-up to 2% of chronic wounds can be malignant, the most common is squamous epithelial carcinoma. Chronic stimulation causes the tumor to start, the suspected ulcer wound edge biopsy is the diagnosis basis. Malignant transformation may occur in scars, burn wounds, sinus, chronic osteomyelitis and even vaccination sites. May be misdiagnosis and mistreatment, delay the illness. The first choice of surgical treatment for malignant transformation wounds.
(6) Primary cancer resection is not complete. The further growth of residual cancer cells (planting) after tumor operation leads to abnormal hyperplasia, rupture and infection of tissue, and can be developed into an non-union surgical wound during the surgical incision, and the tumor incision is recurrent.
3. Characteristics of cancerous wounds
(1) Erosive: Erosion of the surrounding normal tissue
(2) Indistinguishable from normal tissue boundaries (benign envelope)
(3) Rapid growth
(4) on the surface of the formation of the Bulge and skin ulcers, often accompanied by infection, special odor, easy bleeding, infiltration fluid.
4. Cancerous wounds to take active treatment measures:
(1) Surgery preferred. Can not surgery chemotherapy or radiotherapy.
(2) Radiotherapy can narrow the tumor, reduce exudation, relieve pain. As the tumor shrinks, the edges can heal.
(3) Can not cure palliative wound as far as possible to meet patient requirements, by reducing pain, prevention and treatment of infection, prevention and treatment of bleeding, eliminate odor management exudate to improve patient quality of life.
(4) Heart treatment to improve the quality of life is the key. Although the symptoms are controlled, tissue damage strongly stimulates the heart of patients and their families, and can not deny the manifestation of progressive disease, which can lead to depression, shame, distress and loneliness. The doctor’s dressing intermediate attitude can largely affect the patient’s attitude and attitude toward the disease.
(5) Note: Confidence, take a positive approach to encourage patients to avoid the performance of the patient disdain; as inclusive as possible to reduce the sense of isolation; pessimism found when dressing, divert attention; respect the patient’s personality and protect privacy and dignity; Help patients correct treatment of exacerbations.
5. Cancer wound care difficult
(1) Cancer cell growth, the protection of the surrounding tissue treatment to prevent proliferation and planting.
(2) Wound blood vessels by the erosion of tumor cells, bleeding is difficult to control, violations of the aorta may appear fatal bleeding.
(3) The wound appeared a variety of mixed bacteria infection, there stench.
(4) Radiotherapy and chemotherapy affect wound healing.
(5) Accompanied by malnutrition wound healing.
(6) Necrosis and infection in developing tumors that were not given palliative treatment led to uncontrolled exudate and malodor.
