During the past year 25 patients with advanced transitional cell carcinoma were treated with intravenous doxorubicin hydrochloride (Adriamycin), 60 to 75 mg. per square meter of body surface area, every three weeks. Among the 19 evaluable patients, one partial objective remission lasting five months was observed. All 7 patients with bone pain had symptomatic relief and 12 patients had significant subjective improvement lasting an average of six-and-a-half months. Side effects were minimal and consisted of alopecia, mild leukopenia, and mild stomatitis; no significant cardiotoxicity was observed. Doxorubicin hydrochloride appears to have important antitumor activity in advanced urothelial tumors. Controlled clinical trials with this agent alone and in combined drug regimens are needed.

Twenty-eight consecutive adult patients with locally advanced (inoperable) or metastatic soft tissue sarcomas were treated with a chemotherapy regimen (CADOM) including cyclophosphamide, ADR, and DTIC on Day 1 of each course, and vincristine with intermediate-dose methotrexate (200 mg/m2) on Day 15 followed by leucovorin rescue. Twenty-four of the patients were evaluable for response and toxicity. Three (13%) achieved a CR after chemotherapy and 6 (25%) a PR. Two of the PRs were converted to CR after surgical removal of residual tumor. All five patients achieving a CR are alive 12 to 30 months after beginning chemotherapy. Median survival of patients achieving a PR was 18 months and of patients achieving an MR was 7 months. Three of five patients with sarcomas arising from the female genitalia achieved a CR. No treatment-related deaths occurred. There were five instances of leukopenia and fever. Nausea and vomiting, and alopecia were common. Stomatitis, muscle cramps, paralytic ileus, and peripheral neuropathy were occasionally observed. The addition of methotrexate did not improve the response rate when compared with our previous CYV ADIC protocol.

The effects of combination chemotherapy including mitoxantrone (MXN) "M-VEMFH" for advanced breast cancer were studied. The M-VEMFH regimen consisted of MXN 7 mg/m2, VCR 0.7 mg/m2, EX 333 mg/m2, MTX 13.3 mg/m2 i.v. on day 1, 5-FU 333 mg/m2 i.v. from day 1 to day 5 and pred. (H) 60 mg/m2 p.o. with tapering off in 2 weeks. In 7 cases heavily pretreated with combination chemotherapy including ADR, CR 2, PR 2, NC 2 and PD 1 were observed (response rate 57.1%). In 5 cases without prior ADR, PR 1, NC 2 and PD 2 were obtained. One case given 586 mg/m2 of prior ADR died of congestive heart failure after administration of 47 mg/m2 of NXN. One case died of sepsis. The other side effects were stomatitis, vulvitis, abnormal gustation, nausea, vomiting and alopecia. M-VEMFH is effective combination chemotherapy for advanced breast cancer resistant to ADR, but care must be exerted due to the accompanying cardiotoxicity and leukopenia.

Doxorubicin and 5-fluorouracil pharmacokinetics were studied in 19 volunteers with various advanced neoplastic diseases who received 50-90 mg doxorubicin or 600-1000 mg 5-fluorouracil intravenously, followed by plasma and parotid saliva collection over a 75 min period. The extent to which these chemotherapeutic agents are bound to plasma proteins, at concentrations chosen to approximate plasma concentrations, was measured by equilibrium dialysis. Both agents were quantitated by high-performance liquid chromatography. As reported previously, a wide range of plasma levels were found among patients receiving similar doses of either doxorubicin or 5-fluorouracil. It appears that in addition to being quickly cleared from the plasma both chemotherapeutic agents are excreted in detectable amounts in parotid saliva, a route of elimination heretofore given little or no attention. Excretion in the saliva exposes the mucosa of the upper gastrointestinal tract to 5-fluorouracil after intravenous administration and may play a part in causing stomatitis in patients receiving it by this route. Since there are huge interindividual and pronounced intraindividual differences in S/P ratios mostly not systematically related to the drugs' concentration in plasma, the concentration in parotid saliva was not useful in predicting the level of free doxorubicin or 5-fluorouracil in plasma.

In preclinical studies, a doxorubicin liposome formulation containing polyethylene-glycol (Doxil) shows a long circulation time in plasma, enhanced accumulation in murine tumors, and a superior therapeutic activity over free (unencapsulated) doxorubicin (DOX). The purpose of this study was to characterize the pharmacokinetics of Doxil in cancer patients in comparison with free DOX and examine its accumulation in malignant effusions. The pharmacokinetics of doxorubicin and/or liposome-associated doxorubicin were analyzed in seven patients after injections of equivalent doses of free DOX and Doxil and in an additional group of nine patients after injection of Doxil only. Two dose levels were examined, 25 and 50 mg/m2. When possible, drug levels were also measured in malignant effusions. The plasma elimination of Doxil followed a biexponential curve with half-lives of 2 and 45 h (median values), most of the dose being cleared from plasma under the longer half-life. Nearly 100% of the drug detected in plasma after Doxil injection was in liposome-encapsulated form. A slow plasma clearance (0.1 liter/h for Doxil versus 45 liters/h for free DOX) and a small volume of distribution (4 liters for Doxil versus 254 liters for free DOX) are characteristic of Doxil. Doxorubicin metabolites were detected in the urine of Doxil-treated patients with a pattern similar to that reported for free DOX, although the overall urinary excretion of drug and metabolites was significantly reduced. Doxil treatment resulted in a 4- to 16-fold enhancement of drug levels in malignant effusions, peaking between 3 to 7 days after injection. Stomatitis related to Doxil occurred in 5 of 15 evaluable patients and appears to be the most significant side effect in heavily pretreated patients. The results of this study are consistent with preclinical findings indicating that the pharmacokinetics of doxorubicin are drastically altered using Doxil and follow a pattern dictated by the liposome carrier. The enhanced drug accumulation in malignant effusions is apparently related to liposome longevity in circulation. Further clinical investigation is needed to establish the relevance of these findings with regard to the ability of liposomes to modify the delivery of doxorubicin to solid tumors and its pattern of antitumor activity.

Fifty-three patients with AIDS-related Kaposi's sarcoma and no previous treatment with cytotoxic chemotherapy enrolled in a phase II multicenter study to evaluate the safety and efficacy of weekly doxorubicin treatment. Doxorubicin was given intravenously at a dose of 15 mg/m2. Patients were stratified for purposes of analyses by tumor burden and coexistence of HIV-associated signs and symptoms; stratum I included patients with cutaneous disease alone and no symptoms, and stratum II included patients with visceral disease, tumor-associated edema, a previous opportunistic infection, or systemic symptoms. Fifty-one patients were evaluable for toxicity and 50 for tumor response. Five patients had a partial response (10%); 32, a minor response (64%); 12, no change (24%); and one, progression (2%) as the best measurable response. Partial response durations ranged from 4 to 14 weeks. Fifteen patients subsequently showed progression while on treatment. A significantly greater number of patients in stratum I (20.1%) had a partial response compared with those in stratum II (0%, p = 0.009). The major toxicities included nausea (37%), stomatitis (9.8%), mucositis (13.7%), and moderate to severe neutropenia (71%). Neutropenia was dose limiting and resulted in discontinuation of doxorubicin in 18% of the patients. Two patients developed cardiac toxicity. In conclusion, doxorubicin treatment induced relatively few tumor responses and remission durations were short. Treatment was limited by a high rate of toxicity.

Doxorubicin is an antineoplastic drug which has in vitro and in vivo activity against a number of malignancies including Kaposi's sarcoma. Incorporation of doxorubicin into polyethylene glycol-coated (pegylated) liposomes alters the pharmacokinetics of the drug. Liposomal doxorubicin has a smaller volume of distribution and slower plasma clearance than standard free doxorubicin. The liposomal formulation achieves higher concentrations in the highly vascularised lesions of Kaposi's sarcoma than in normal tissue. Liposomal doxorubicin monotherapy in patients with AIDS-related Kaposi's sarcoma produced overall response rates (complete plus partial) of 43 and 59% in large comparative studies and 67 to 100% in noncomparative studies which included > or = 20 patients. In comparative studies, liposomal doxorubicin was significantly more effective than the combination of standard doxorubicin, bleomycin and vincristine (overall response rates of 43 and 25%, respectively) and bleomycin and vincristine (BV) [overall response rates of 59 and 23%, respectively]. In addition, overall response rates to the liposomal drug were higher in both treatment arms of 2 smaller comparative studies which compared liposomal doxorubicin with BV, but significant between-treatment differences were not detected. Patient numbers in these 2 studies, however, may have been too small to detect significant differences. Liposomal doxorubicin is generally well tolerated. Myelosuppression is the most common dose-limiting adverse effect in patients with AIDS and Kaposi's sarcoma. Neutropenia occurs most often; anaemia and thrombocytopenia occur less frequently, as do nausea and vomiting and stomatitis. Palmar-plantar erythrodysaesthesia occurs in some patients, most commonly after 6 to 8 weeks of chemotherapy. Although symptoms may occasionally be severe, the syndrome usually does not require dosage reduction or treatment delay. Limited data suggest that the incidence of cardiotoxicity may be lower after liposomal doxorubicin than after equivalent doses of standard doxorubicin. Overall, liposomal doxorubicin appears to be one of the most active single agents available for treating patients with AIDS-related Kaposi's sarcoma. The therapeutic potential of liposomal doxorubicin administered in combination with other active agents to patients with Kaposi's sarcoma is, as yet, unknown. However, administered alone, the drug seems to be more effective than the best available combination chemotherapy regimens.

We treated 20 women with locally advanced breast cancer between January 1991 and September 1996. The treatment regimen included 4 cycles of intensive doxorubicin (30 mg/m2/d on 3 consecutive days every 2 weeks with G-CSF support), followed by appropriate surgery, followed by high dose therapy with cyclophosphamide, carboplatin and thiotepa (STAMP V, CTCb). Of the 20 patients, seven presented with inflammatory breast cancer, three with Stage IIIB, seven with stage IIIA, one with multifocal Stage IIB and two with Stage IV M1 (ipsilateral supraclavicular lymph node involvement) (including one who had an inflammatory primary) disease. Six patients had not undergone mastectomy at the time of entering the protocol. These six received the doxorubicin in a neoadjuvant fashion and were thus evaluable for tumor response. The remaining 14 received doxorubicin as adjuvant therapy prior to intensification and transplantation. All patients underwent local-regional radiation therapy and were placed on oral tamoxifen. Doxorubicin was well tolerated in this schedule with all but three patients receiving all their cycles on schedule. Both BM and PBPC were easily collected after this regimen and, when reinfused, resulted in the prompt recovery of granulocytes (median 11 days to 500 absolute granulocyte count) and platelets (median 13 days to 20,000 platelets). The six patients who received doxorubicin prior to mastectomy all had major clinical responses, but were found to have microscopic focii of breast cancer in the mastectomy specimens. The overall treatment was well tolerated with the exception of one treatment-related death (5%). The overall and relapse free survival are 70% and 58% respectively with a median follow-up of 40 months (range 12-74 months). When the Stage IV patients are censored, the relapse-free survival rate is 69%. In the bone marrow transplant phase of treatment, the major non-hematologic toxicities were stomatitis (70%) and anorexia requiring parental nutrition (75%).

Doxorubicin and paclitaxel both display strong antitumor activity in the treatment of breast cancer. The optimal schedule of this combination, however, remains undefined. In this phase I and pharmacologic study, we administered weekly 12 mg/m2 doxorubicin as a bolus infusion immediately followed by a 1 h 80 mg/m2 paclitaxel infusion to patients with metastatic breast cancer. A total of 119 weekly courses were delivered to seven patients. Grade IV neutropenia was observed in two patients at the first dose level, thus already defining the maximum tolerated dose. Pronounced non-hematologic toxicities were mild neuropathy (grade I: 39%) and stomatitis (grade I: 19%, grade II: 8%). No signs of cardiac toxicity were observed with this dose schedule. Three partial responses were achieved in this group of heavily pretreated patients. The pharmacokinetics of paclitaxel, doxorubicin and Cremophor EL with this schedule were analyzed. Overall, the schedule was well tolerated and combined with its preliminary response rate justifies further evaluation in phase II studies.

Doxorubicin is considered among the most active single agents used against advanced breast cancer. Recent advances in the design of liposomes as carriers of cytotoxic drugs have resulted in a new formulation of doxorubicin with improved pharmacokinetic and tumor-localizing properties. The objectives of this dose-escalating pilot study were to evaluate the efficacy and safety of the sterically stabilized, pegylated liposomal doxorubicin (Lipo-Dox) for the treatment of metastatic breast cancer. Lipo-Dox was given at the dosage of 45 mg/m2 over 1 hr of intravenous infusion every 4 weeks initially and could be escalated up to a maximum of 60 mg/m2. Response was assessable in 17 of 19 intent-to-treat patients. An objective response was achieved in 41.2% (95% confidence interval: 17.8%-64.6%) of patients (5.9% complete response and 35.3% partial response), and 23.5% had stable disease. Median time to disease progression was 163 days. Major treatment-related toxicities included neutropenia, stomatitis, and skin toxicity in this dose-escalation program. Impressively, no grade 4 toxicities have ever been observed. The only grade 3 nonhematological toxicity ever to occur was reversible skin toxicity, presented as palmar-plantar erythrodysthesia. No severe nausea/vomiting, wig-necessary alopecia, or significant cardiac function change were encountered. In conclusion, Lipo-Dox is shown by this first reported pilot study to be an active agent for treatment of advanced breast cancer with a safety profile that differs markedly from free doxorubicin. The dosage of 45-60 mg/m2 every 4 weeks was well tolerated. Because myelosuppression and other nonhematological toxicities associated with Lipo-Dox were generally mild and acceptable, further assessment of this drug particularly in combination with other chemotherapeutic drugs in the management of early or advanced breast cancer is suggested.
