Iv Baker's antifol (BAF) (250 mg/m2/day X 3 consecutive days) was administered to 34 patients with metastatic sarcoma. All patients had received extensive prior therapy including prior chemotherapy and had progressive disease at the start of the study. Liver and renal functions were normal in all patients. Of 29 patients evaluable for response, 25 demonstrated progressive disease and four had stable disease for periods of from 1 to 6 months. No objective responses were observed. The other five patients died from 3 to 12 days after initiation of therapy. Toxicity included myelosuppression of significant degree in nine patients, gastrointestinal effects of nausea and vomiting in seven, stomatitis in three, and dermatitis in four. Most toxicity was mild to moderate, although one drug-related death due to marked myelosuppression was seen. In conclusion, BAF is considered to be insignificantly active in the secondary treatment of metastatic sarcomas at the dose and schedule studied.

Didemnin B is a depsipeptide derived from a Caribbean tunicate (sea squirt) that has demonstrated antineoplastic activity against a variety of murine tumor models, including the L1210 and P388 leukemia, the B16 melanoma, and M5076 sarcoma cell lines. Based on these data, we designed a phase II trial in which 15 patients with measurable, unresectable colorectal cancer were treated with Didemnin B at an initial dosage of 3.47 mg/m2 over 30 minutes administered by intravenous infusion every 28 days; the dosage was altered in accordance with the toxicity observed, with only one patient requiring a dosage reduction for pronounced nausea and vomiting. No hematologic or nonhematologic toxicity developed. No complete or partial responses were observed. These results do not compare favorably with results of treatments using other single agents or combinations that are currently available for the treatment of advanced colorectal cancers. However, because of the tolerable levels of toxicity experienced by in our patients, it is possible that an insufficient dose of the medication was delivered. We concluded that Didemnin B is not active against of colorectal cancers at the dosage and schedule at which it was administered in this study.

The chemotherapeutic approach to advanced sarcomas of bone and soft tissue is reviewed. The most active single agents against osteosarcoma are doxorubicin (overall response rate, 21%), methotrexate (30% to 40%), cisplatin (25%), and ifosfamide (28%). Current multimodality treatment for Ewing's sarcoma consists of combination chemotherapy with doxorubicin, vincristine, and cyclophosphamide (or ifosfamide in current trials) prior to and concurrent with radiation therapy for the involved bone. In soft tissue sarcomas, doxorubicin is the most active single agent, with overall response rates ranging from 15% to 35%. Dacarbazine has a single-agent response rate of 16%. Ifosfamide has documented activity in sarcoma patients who have failed treatment with doxorubicin-containing regimens. The combination regimen currently producing the highest response rates in soft-tissue sarcomas is doxorubicin/dacarbazine/ifosfamide. Doxorubicin and dacarbazine should be administered by continuous infusion to reduce the severity of nausea and vomiting and the risk of cardiotoxicity. Ifosfamide can be given by continuous infusion or in divided doses with mesna to mitigate urothelial toxicity.

Thirty-seven patients with advanced soft tissue sarcoma were treated with merbarone utilizing a daily intravenous schedule for five days. Only one partial response was observed in the thirty-three evaluable patients. The major toxicities were renal, with elevation of creatinine and/or proteinuria, and gastrointestinal, with mild to moderate nausea and vomiting. Merbarone in this dose and schedule has minimal activity in soft tissue sarcoma.

The antiemetic activity of two different high doses and schedules of metoclopramide in dacarbazine-treated cancer patients was compared in a double-blind crossover study. Regimen A consisted of metoclopramide [2 mg/kg x 4 intravenously (i.v.)] plus methylprednisolone (250 mg x 2 i.v.) plus diphenhydramine (50 mg x 2 i.v.). Regimen B consisted of metoclopramide (3 mg/kg x 2 i.v.) plus dexamethasone (20 mg i.v.) and diphenhydramine (50 mg i.v.). Both treatments were administered for the first 2 days of 5-day dacarbazine chemotherapy. Thirty-two patients (13 men and 19 women) affected by melanoma and sarcoma were entered in the study. Complete protection against nausea and vomiting for the first 2 days of chemotherapy in both antiemetic regimens was not significantly different. Patient preference and tolerance of the two antiemetic treatments were similar. Regimen B, employing a lower dosage of metoclopramide and steroids and using a more simple schedule of administration should be the preferred treatment.

The EORTC Soft Tissue and Bone Sarcoma Group has conducted a phase II trial in 33 eligible patients with metastatic soft tissue sarcoma with nimustine 100 mg/m2 every 6 weeks. In 31 evaluable patients there were 3 (10%) partial responses lasting 4.5, 6 and 7.5 months, and 5 cases of stable disease. 12 patients had progressive disease and 11 patients early progressive disease. Toxicity consisted mainly of leukopenia and thrombocytopenia and nausea and vomiting. It is concluded that nimustine has only minor activity in soft tissue sarcoma.

Forty-four of 50 adult patients with advanced soft-tissue sarcoma who had received previous chemotherapy were evaluable for response after treatment with DTIC. The therapeutic schedule consisted of DTIC 1.2 g/m2 infused over 20 minutes, and repeated every 3 weeks. There were 1 complete and 7 partial remissions (objective activity 18%, 95% C.I. 7%-29%), with a median duration of 8 weeks (range 5-19), with the complete remission lasting 1 yr. Hematologic toxicity was dose-limiting; W.H.O. greater than or equal to 3 values were observed for WBC in 36%, and for platelets in 26% of patients. The non-hematologic toxicity included nausea and vomiting (90%), a flu-like syndrome (49%), diarrhea (35%), pain in the infused vein (28%) and hypotensive episodes (4%). Intermittent high-dose DTIC is active in advanced soft-tissue sarcoma and should be considered for inclusion in combination regimens.

Didemnin B is a depsipeptide extracted from the marine tunicate Trididemnin cyanophorum. This agent is a potent inhibitor of L1210 growth in vitro and has activity against murine B16 melanoma, P388 leukemia, and M5076 sarcoma in vivo. The results of preclinical toxicologic tests demonstrated abnormalities in clotting parameters thought to be secondary to drug-induced liver dysfunction. Thirty-five patients with advanced cancer received didemnin B according to a 5-day bolus schedule with dose levels ranging from 0.03 to 2.00 mg/m2/d. The dose-limiting toxicity was nausea and vomiting. Sporadic elevation of the hepatic enzyme level occurred but was not dose limiting. Two patients had anaphylactic symptoms possibly related to the 5% polyoxyethylated castor oil (Cremophor EL, BASF, Ludwigshafen, Germany) vehicle during the drug infusion. Clinical bleeding was not observed and myelosuppression was not significant. No partial or complete tumor responses were seen. The recommended Phase II dose for the 5-day schedule is 1.6 mg/m2/d.

A phase I trial of piritrexim was conducted by use of a prolonged, low-dose oral schedule. A number of different regimens were tested, including daily dosing for 21 days followed by 7 days of no drug therapy; continuous dosing; and daily dosing for 5 of 7 days for 3 consecutive weeks followed by a week of rest. Dose escalation was accomplished by increasing the dosing frequency from once a day to twice a day and then to three times a day and by increasing the number of days of administration. Fifty-one patients with advanced cancer were entered in the study. One hundred twenty-four (96%) of 129 courses were considered assessable. Myelosuppression proved to be the dose-limiting toxic effect. Other toxic effects included stomatitis, nausea and vomiting, anorexia, diarrhea, skin rash, fatigue, and elevation of liver transaminase levels. Antitumor activity was observed in patients with melanoma and bladder cancer, and disease stabilization occurred in those with sarcoma and pheochromocytoma. The recommended dosing schedule for phase II clinical trials is 25 mg three times a day for 5 days for 3 consecutive weeks followed by 1 week of no drug therapy.

Thirty-seven patients (pts) with previously untreated and measurable advanced soft tissue sarcoma entered this phase II study: 22 men and 15 women were included. Median age was 58 (range: 20-71). The starting dose of epirubicin was 100 mg/m2 IV bolus every 3 wks. In the case of minimal myelosuppression, the dose was increased by 10 mg/m2 to 130 mg/m2 (Mean dose per cycle: 105 mg/m2). Median cumulative dose of epirubicin administered was 445 mg/m2 (range: 200-1320 mg/m2). From 32 evaluable pts, one had a complete response (CR), 5 a partial response (PR), (CR + PR = 18.7% +/- 13.8%), 12 showed no change (37.5%) and 14 had progressive disease. The number of complete or partial responses observed was not modified by increasing the doses of epirubicin. Median time to progression was 4 months. From 32 pts evaluable for toxicity, hematologic toxicity at d 21 was mild. Non hematological toxicities consisted of nausea and vomiting in 74% of pts (WHO grade 3 = 5%), stomatitis in 12.2% (WHO grade 3 = 3%) and alopecia in 91% (WHO grade 2-3 = 72%). No cardiac dysfunction was recorded during the treatment, even though 7 patients received more than 800 mg/m2 of epirubicin (median: 850 mg/m2, range: 810-1320 mg/m2). The results of this study show that epirubicin is an active drug in advanced soft tissue sarcoma.
