Oxaliplatin-based adjuvant chemotherapy

for the treatment of advanced limb STS Despite the small sample size of this study, our results show a clear advantage in the use of oxaliplatin-based neoadjuvant chemotherapy: the tumor response rate in the experimental group was 87%, limb-preserving operations were carried out in all cases. In addition, this combination therapy may also prove beneficial for the treating of distant metastatic tumors, this hypothesis is supported Kinase Inhibitor Library by the fact that one patient’s lung metastasis disappeared after the first cycle of chemotherapy. Our follow-up analysis at a median of 24 months revealed that all patients from the experimental group who showed significant benefits of chemotherapy before surgery were still alive, including survivors with and without tumors. The only death

occurred in a patient who did not respond to the chemotherapy and had metastases in both lungs before surgery. In general, the prognoses for patients with distant metastases were much worse, with a shorter progression-free stage. Prognoses were best for patients who had no distant metastasis before surgery and who showed significant chemotherapeutic response, this was Z IETD FMK similar to observations seen in another study [12]. Patients in the experimental group mainly benefited from tumor-free survival, without a corresponding increase in overall survival. There was no significant difference in overall survival time between experimental and control groups, which may reflect the

short follow-up time and the small sample selleck chemical size of the study. Future studies using larger cohorts and a longer follow-up time may reveal survival benefits. In addition, we discovered that the two CR cases from the experimental group were both patients with neurogenic tumors. Whether neurogenic tumors are more sensitive to oxaliplatin-dacarbazine treatment is worthy of further investigation [13]. References 1.
