For keloid scars, single therapy often has poor efficacy and a high recurrence rate. Relevant experts conducted a study on 60 keloid patients who underwent surgical excision followed by either radionuclide patch treatment or local injection of glucocorticoids, comparing these combined treatments with 30 cases treated solely with local injections of glucocorticoids. The results showed that combined treatment had better outcomes than single treatment. The 90 keloid patients were randomly divided into three groups: A, B, and C.
1. Surgical Excision: For groups A and B, all keloid lesions were surgically excised under local anesthesia. For smaller lesions, incisions were made along the borders of the keloid, removing the scar tissue while ensuring minimal tension after suturing through subcutaneous separation. For larger lesions, excision combined with autologous full-thickness skin graft transplantation was performed, ensuring the skin grafts were sutured without tension, slightly larger than the resulting wound to avoid post-surgical tension. Post-operative fixation with appropriate pressure was applied, and all donor sites were from the abdomen.
2. Sr-90Y Patch Treatment: For group A patients whose surgical wounds were directly sutured, Sr-90Y radioactive skin patch treatment began 3-4 days post-surgery. For those who received skin grafts, the treatment commenced once the graft was fully viable. During treatment, the active surface of the Sr-90Y patch treatment device was placed in direct contact with the suture site, using small doses administered in multiple sessions. To prevent scar formation at the donor site, Sr-90Y patch treatment was also administered post-operatively.
3. Local Glucocorticoid Injection Treatment: For group B patients, intraoperative and postoperative glucocorticoid injection treatment was administered. After subcutaneous suturing of the excised lesion, triamcinolone acetonide injection was administered in multiple points just beneath the dermis along both sides of the cut edge. For group C patients, a high-pressure injector was used to administer triamcinolone acetonide into the lesion until the lesion's surface turned white.
4. Efficacy Evaluation: Based on a three-level classification method:
- Cure: Disappearance of pain and itching, complete softening and flattening of the scar, feeling soft upon touch without hard lumps or cord-like marks; no recurrence within 12 months after cure.
- Marked Effect: Disappearance or near disappearance of pain and itching, 60%-70% of the scar softened and flattened or reduced from severe to moderate or mild; no recurrence within 12 months after cure.
- Effective: Local recurrence but not exceeding the original lesion area, still experiencing pain and itching but with some improvement.
- Ineffective: Pain and itching symptoms reduce or remain unchanged, no significant changes in scar texture or size, or recurrence within 12 months after initially reaching clinical cure standards.
Keloid scars are a type of skin fibrosis disease characterized by excessive production and deposition of collagen fibers and other extracellular matrix components. Patients typically present with excessive proliferation of fibrous tissue in localized areas of the skin, extending beyond the wound, causing local pain and itching. Its treatment is challenging, as there is currently no particularly effective single treatment method, mainly due to the difficulty in controlling its high recurrence rate. Borok et al. reported a recurrence rate of 50%-80% for simple surgery alone, so currently, single surgery treatment is not recommended. Instead, a combination of surgery with radiation or drug therapies is advocated.
The mechanism of action of Sr-90Y patch treatment involves beta rays released during the decay process of radioactive isotopes on the patch acting on the fibroblasts producing collagen in scar tissue. The fibroblasts undergo degeneration when exposed to ionizing radiation, reducing the synthesis and deposition of collagen, thereby achieving the therapeutic purpose. The mechanism of local glucocorticoid injection treatment is through inhibiting globulin and collagenase inhibitors to increase collagen degradation, reducing collagen synthesis and fibroblast proliferation, alleviating inflammatory reactions in wounds, decreasing the synthesis of elastin by fibroblasts, inhibiting fibroblast proliferation and apoptosis, and reducing the synthesis of Type I, II, and III collagen mRNA in normal skin and scar fibroblasts, thereby inhibiting scar hyperplasia and achieving the therapeutic purpose.
By adopting two combined methods—surgery combined with radiotherapy and surgery combined with glucocorticoid injection treatment—for treating keloid scars, the fundamental removal of hyperplastic keloid lesions can be achieved, relieving contracture at the scarred area. Qiuyunfeng repairs local shape changes or mobility impairments caused by excessive keloid growth, significantly improving aesthetic deformities. From an aesthetic perspective, this enhances the value of keloid scar treatment. By employing the aforementioned two treatment mechanisms, the recurrence rate is greatly suppressed, significantly improving clinical efficacy.
