Cardiac safety of pegylated liposomal doxorubicin (Doxil/Caelyx) demonstrated by endomyocardial biopsy in patients with advanced malignancies.

Although conventional doxorubicin demonstrates broad activity, its clinical use is limited by cardiotoxicity. A more recent analysis suggests conventional doxorubicin-related cardiotoxicity occurs more frequently and at lower cumulative doses than previously reported. Pegylated liposomal doxorubicin, designed to maintain or improve conventional doxorubicin activity while reducing toxicities, has demonstrated improved cardiac safety versus conventional doxorubicin.

Prognostic factors for survival in metastatic breast cancer during first-line paclitaxel chemotherapy.

The prognostic value of various demographic, clinical and laboratory characteristics was investigated in 54 patients with metastatic breast cancer during first-line paclitaxel chemotherapy. As a single-agent treatment, paclitaxel (175 mg/m2) was given by 3-hour infusion every three weeks. The overall response rate was 30%.

Time trends in organ position and volume in patients receiving prostate three-dimensional conformal radiotherapy.

Using multiple computed tomography (CT) scans, 50 patients undergoing prostate radiotherapy were tested for clinically significant time trends in the target and surrounding critical structures. Significant trends were observed toward increasing bladder volume and increasing bowel-to-planning target volume separation; however, no trends were observed in the prostate, seminal vesicles, or rectum. The subset of patients undergoing hormone therapy was also tested and did not independently exhibit any significant time trends.

Phase I study of doxil-cisplatin combination chemotherapy in patients with advanced malignancies.

Purpose: Our first objective was to evaluate the feasibility of administering a combination of Doxil, a pegylated liposome formulation of doxorubicin, and cisplatin and to determine the maximum tolerated dose of the combination. A secondary objective was to examine Doxil peak and 7-day postinjection plasma levels at the various dose levels tested.

Methods: Patients with advanced solid tumors were treated every 4 weeks with cisplatin on day 1 and Doxil on day 2.

Skin toxic effects of polyethylene glycol-coated liposomal doxorubicin.

Objectives: To record the profile of toxic effects of polyethylene glycol-coated liposomal doxorubicin hydrochloride (Doxil) to the skin, and to evaluate whether the long circulation pattern and enhanced accumulation of liposomes in specific skin sites will result in any unique presentations.

Design: Patients were accrued in the frame of dose-range-finding studies that examine the toxic effects and antitumor activity of Doxil therapy in metastatic breast and prostate cancers. All patients receiving Doxil were instructed to report any skin eruption or discomfort.
