pirarubicin and Soft-Tissue-Neoplasms

Eighty patients with measurable metastatic colon or renal cancer, melanoma, or sarcoma entered these Phase II studies. A dose of 25 mg/m2/day of Pirarubicin (THP) for 3 consecutive days every 4 weeks for the first patients, and then 20 mg/m2/day for 3 days every 3 weeks was given by i.v. push. These patients received 225 cycles for a median cumulative dose of 165 mg/m2 (range: 55-630). The mean number of cycles given was 2.8 (range: 1-8). Only 3 partial responses and 18 stable disease (22%) were observed. Hematologic toxicity was the main problem; it was responsible for one death and a 19% and 44% incidence of grade 3 and 4 WHO neutropenia, respectively. Alopecia was rare (4%). Chemotherapy was discontinued in three cases because of suspicion of cardiac toxicity, but only one patient had a significant drop in left ventricular ejection fraction at a cumulative THP dosage of 120 mg/m2. A lack of efficacy in renal and colon cancer and melanoma was presupposed and confirmed by these trials. Due to pretreatment with anthracycline in most patients, definite evaluation of THP in soft tissue sarcoma could not be given.

Dedifferentiated liposarcoma, one of the most deadly types of soft tissue sarcoma, is an aggressive and high-grade form of liposarcoma. Liposarcoma occurs most commonly in the retroperitoneum, extremities and trunk, but less frequently in the female genital tract. The vagina is a very rare site of origin. Herein we report the first case of dedifferentiated Liposarcoma deriving from vagina and discuss its clinical course.. A 38-year-old female patient presented to our institution with a painless vaginal mass. Abdominal computed tomography showed a 17.6 cm× 10.4 cm solid mass originating from the right lateral wall of her vagina. Then she underwent complete surgical resection of the tumor mass, and postoperative pathological result confirmed the diagnosis of dedifferentiated liposarcoma deriving from vagina. Six courses of combination chemotherapy with pirarubicin plus ifosfamide were performed after surgery. The patient remains with no evidence of disease recurrence with 13 months of follow-up.. Liposarcoma is very rare in female genital tract, and more rare for dedifferentiated liposarcoma in gynecologic field. Little is known about the clinical characteristics, pathological diagnosis, prognosis and optimal management strategy of vaginal dedifferentiated liposarcoma. Complete surgical resection followed by systemic chemotherapy is suggested to be standard treatment for dedifferentiated liposarcoma. Combination chemotherapy with pirarubicin and ifosfamide may be effective for treating vaginal dedifferentiated liposarcoma.

Clinical study suggests that 72-hour continuous infusion (CIV) of MAID regimen is more effective and achieves longer time of no progression than ADR-based two-drug regimen in advanced soft tissue sarcoma (ASTS) treatment, but has no improvement on the long-term survival. Because of the severe grade 3/4 toxicities as well as treatment-related deaths, the regimen has not been widely applied in ASTS. This study was to investigate the efficacy and toxicity of the modified MAID regimen in ASTS treatment.. In the modified regimen, adriamycin (ADR) was substituted with tetrahydropyranyl adriamycin (THP-ADR) and the application of ifosfamide (IFO) was modified. All enrolled patients received chemotherapy (IFO 2,000 mg . m(-2), 4h, day 1-3; mesna 1,200 mg . m(-2) at 0, 4 and 8 hours of IFO infusion, day 1-3; THP-ADR 20 mg . m-2 and dacarbazine (DTIC) 333.3 mg . m(-2) were mixed in the same bag or pump, CIV for 3 days). The therapy was repeated every 3 weeks for at least 2 cycles before evaluating the effects and toxicities. The patients received follow-up every 2 months after completing 2 cycles until the study was finished. Life table was used to calculate long-term survival rates and time to progression.. Fifty-four cases of evaluable patients had completed at least 2 cycles of modified MAID chemotherapy. The overall response rate was 42.59%. The toxicities were mild. Grade 3/4 neutropenia and thrombocytopenia were 25.93% and 16.17%, respectively. Neutropenia fever was 11.11%. There were no other toxicities, such as hepatic and renal toxicities; no central nervous system toxicity and treatment-related deaths. During 2 year follow-up, time to progression was 7 months, 1- and 2- year survival rates were 61.11% and 36.36%, respectively.. Modified MAID regimen simplifies the application of treatment procedure compared with original regimen, which three drugs have to be CIV simultaneously. Moreover the modified MAID regimen has better survival rates in ASTS, with milder toxicity and better tolerance.

Synovial sarcoma with pulmonary metastases appeared to be sensitive to multiagent chemotherapy of Pirarubicin, Ifosfamide, and Vincristine Sulfate. However, this chemotherapy regimen could not be continued because of severe hemorrhagic cystitis due to the toxicity of Ifosfamide. Even in the advanced stage, this multiagent chemotherapy would be useful for the treatment of synovial sarcoma, if hemorrhagic cystitis could be prevented.
