Therapy Facilitates Ulcer Wound Healing of Superficial Malignant Tumors
Malignant tumors (cancer cells) are metastatic and invasive, and cancer cells can spread throughout the body through hematogenous, lymphatic and implantation metastases. Clinically, the most common tumor metastasis sites are lung, liver, brain, bone, etc. Some patients will have metastasis on the body surface, while in some cases, the tumor directly spreads or invades the body surface.1 The appearance of superficial malignant tumor usually indicates that the tumor is in the middle and late stage. However, many patients seek medical treatment only after the superficial tumor has grown, ruptured, and become infected. The ulceration of superficial malignant tumors can lead to wound bleeding, exudation, pain, infection, and scar hyperplasia, which makes the wound unhealed for a long time, greatly reducing the quality of life of patients.2 At present, surgical resection, chemotherapy and radiotherapy are the mainstays of treatment for superficial malignant tumors.3 Clinically, such patients are required to maintain local dryness of the wound, but frequent dressing changes and large surgical wound make it difficult to keep the wound dry; Moreover, chemotherapy is easy to cause a large amount of exudate in the wound to be in a moist state, coupled with the skin damage aggravation resulted from radiotherapy, leading to the susceptible to wound bleeding and infection and consequently delayed wound healing … read more
