Detailed Description
Sarcoma is a rare solid tumor, accounting for about the malignant tumors in adults. About 80% of sarcoma originated from soft tissue, and the remaining 20% originated from bone. In a word, soft tissue sarcoma consists of more than 50 different histological subtypes. Leiomyosarcoma is one of the most common soft tissue sarcomas, and its incidence is estimated to be between 10% and 20% in all newly diagnosed soft tissue sarcomas. Leiomyosarcoma accounts for a large proportion of soft tissue and abdominal-pelvic sarcoma, second only to liposarcoma, and is the main sarcoma caused by large vessels. In addition, uterine leiomyosarcoma mainly comes from smooth muscle cells in myometrium, which can exist alone or coexist with leiomyoma, and is the most common uterine sarcoma.
Local and distant metastasis can occur in leiomyosarcoma. Generally speaking, patients with leiomyosarcoma whose tumor diameter is less than 5cm have a better prognosis. More than 40% of dermal tumors are prone to recurrence, but rarely metastasize. On the contrary, 1/3 of subcutaneous tumors can metastasize, with poor prognosis, and often metastasize to liver and lung, which requires regular follow-up visits to hospitals. Leiomyosarcoma from skin has a good prognosis and can be cured. Leiomyosarcoma originating from soft tissues, bones and blood vessels of trunk has poor prognosis and generally cannot be completely cured.
Surgical resection is the main treatment for leiomyosarcoma, and the tumor tissue should be completely removed as far as possible. Those involved in lymph nodes which are within the scope of resection should be removed together, but lymph node dissection is not advocated. After operation, active chemotherapy and active prevention should be taken to prevent recurrence. The treatment period is 6 ~ 12 months. As an auxiliary treatment after surgery, radiotherapy is a non-invasive treatment. Preoperative radiotherapy can improve the resection rate and organ preservation rate, while postoperative radiotherapy can reduce the local recurrence rate and improve the survival rate.
The most life-threatening aspect of leiomyosarcoma is its tendency to blood-borne transmission, so it needs systemic control. For patients who cannot be completely removed after surgical resection or who will cause severe physical disability or even life-threatening. However, the treatment of resectable and metastatic diseases is still unsatisfactory because leiomyosarcoma is moderately sensitive to chemotherapy. Only three drugs-epirubicin, ifosfamide and dacarbazine (DTIC) have effective activity in patients with soft tissue sarcoma, and the response rate is about 20%3-4 in the second phase study. Compared with single drug, combined chemotherapy did not improve the overall survival rate by 4-6. The median survival rate was still about 12 months. Obviously, it is necessary to find new drugs with soft tissue sarcoma activity to improve the treatment of these tumor patients.
Temozolomide is an alkylating agent and an antitumor drug, which can pass through the blood-cerebrospinal fluid barrier and is clinically used for the first-line treatment of brain tumors. Cytotoxicity caused by DNA methylation and mismatch repair 6-7. A Phase II clinical study on the efficacy and toxicity of temozolomide in patients with unresectable or metastatic soft tissue sarcoma. Results The dosage regimen of temozolomide used in the study was well tolerated and had moderate activity against unresectable or metastatic leiomyosarcoma of uterus and non-uterus. In 25 patients, the overall objective remission rate was 8%. At the median follow-up of 13.2 months, the median progression-free survival time and median overall survival time were 2.0 months (95% confidence interval [95% CI], 1.7-2.3) and 13.2 months (95% CI, 4.7-31.1), respectively. All patients suffered from uterine leiomyosarcoma or non-uterine leiomyosarcoma. In the subset analysis of these patients, the objective remission rate was 18% (2 out of 11 patients), while the disease stabilized in 3 out of 11 patients (27%). For this subgroup, the median follow-up time was 24.4 months, the median progression-free survival time and median overall survival time were 3.9 months (95% CI, 1.9-21.9) and 30.8 months (lower limit 95% CI, 7.8), respectively.
A single dose of epirubicin is the standard systemic treatment for soft tissue sarcoma, followed by leiomyosarcoma. Epirubicin, as a single drug, has a reported response rate of 10% to 25% (Krikelis and Judson analyzed retrospectively in 2010), although leiomyosarcoma seems to be inferior to other sarcoma subtypes, such as synovial sarcoma and liposarcoma. Retrospective clinical data of 2185 patients with sarcoma treated with epirubicin showed that the response rate of leiomyosarcoma was low (11%).
Therefore, this study designed to evaluate the efficacy and safety of temozolomide for injection combined with epirubicin in the first-line treatment of advanced leiomyosarcoma, and to observe and evaluate the efficacy and safety of temozolomide for injection combined with epirubicin in the first-line treatment of advanced leiomyosarcoma.
