Abstract:

Objective

To investigate the safety and efficacy of liposomal doxorubicin monotherapy in elderly soft tissue sarcoma.

Methods

From January 2017 to January 2021, the clinical data of all elderly patients with soft tissue sarcoma who received surgical treatment and adjuvant chemotherapy in PLA 960th Hospital were retrospectively analyzed. The patients' gender, age, tumor type, site of disease, limb salvage, adjuvant chemotherapy regimen, adverse reaction of chemotherapy, disease-free survival time, and overall survival time were analyzed. All patients were divided into liposome doxorubicin chemotherapy group and doxorubicin and ifosfamide combined chemotherapy group. The safety and clinical effectiveness of chemotherapy between the two groups were statistically analyzed.

Results

Among the 23 patients, 20 (87.0%) elderly patients with soft tissue sarcoma were included in this study, including 13 males (65.0%) and 7 females (35.0%). The age of onset was 60-72 years old, with an average age of 66.0 years. The pathological types of all patients were highly malignant, and undifferentiated pleomorphic sarcoma was the most common pathological type. There were 7 patients in liposomal doxorubicin single drug chemotherapy group and 13 patients in doxorubicin ifosfamide combined chemotherapy group. The 10 most common adverse reactions of chemotherapy such as nausea, vomiting and leucopenia were counted. Referring to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.0.3 standard, there were 16 times of grade 1-2 adverse reactions and no grade 3-5 adverse reactions in single drug chemotherapy group. There were 60 times of grade 1-2 adverse reactions, 7 times of grade 3 adverse reactions and 4 times of grade 4 adverse reactions, and no grade 5 adverse reactions in combined chemotherapy group. Statistical analysis between groups showed that the combined chemotherapy group had more chemotherapy complications than the single drug chemotherapy group, and the difference was statistically significant (χ2=8.811, P=0.003), the minimum value of leukocyte after chemotherapy was lower in the combined chemotherapy group, and the difference was statistically significant (F=6.605, P=0.019). The median PFS in the monotherapy group was 12 months. The median PFS in the combined chemotherapy group was 17 months, the median OS in the single drug chemotherapy group did not appear during the follow-up time, and the median OS in the combined chemotherapy group was 35 months. There was no difference between the groups.

Conclusion

Liposomal doxorubicin monotherapy has better safety and similar clinical efficacy to combined chemotherapy in elderly soft tissue sarcoma.
