Abstract
Acidic pH in the tumor microenvironment is associated with cancer metabolism and creates a physiological barrier that prevents from drugs to penetrate cells. Specifically, ionizable weak-base drugs, such as doxorubicin, freely permeate membranes in their uncharged form, however, in the acidic tumor microenvironment these drugs become charged and their cellular permeability is retarded. In this study, 100-nm liposomes loaded with sodium bicarbonate were used as adjuvants to elevate the tumor pH. Combined treatment of triple-negative breast cancer cells (4T1) with doxorubicin and sodium-bicarbonate enhanced drug uptake and increased its anti-cancer activity. In vivo, mice bearing orthotropic 4T1 breast cancer tumors were administered either liposomal or free bicarbonate intravenously. 3.7 ± 0.3% of the injected liposomal dose was detected in the tumor after twenty-four hours, compared to 0.17% ± 0.04% in the group injected free non-liposomal bicarbonate, a 21-fold increase. Analyzing nanoparticle biodistribution within the tumor tissue revealed that 93% of the PEGylated liposomes accumulated in the extracellular matrix, while 7% were detected intracellularly. Mice administered bicarbonate-loaded liposomes reached an intra-tumor pH value of 7.38 ± 0.04. Treating tumors with liposomal bicarbonate combined with a sub-therapeutic dose of doxorubicin achieved an improved therapeutic outcome, compared to mice treated with doxorubicin or bicarbonate alone. Interestingly, analysis of the tumor microenvironment demonstrated an increase in immune cell' population (T-cell, B-cell and macrophages) in tumors treated with liposomal bicarbonate. This study demonstrates that targeting metabolic adjuvants with nanoparticles to the tumor microenvironment can enhance anticancer drug activity and improve treatment.

Abstract
BACKGROUND In adults, it has been shown that the pharmacokinetics of doxorubicin are highly variable, despite standardization of the dose based on body surface area (BSA). The purpose of this study was to determine the plasma concentrations of doxorubicin and its active metabolite doxorubicinol in children treated for acute lymphoblastic leukemia (ALL). PROCEDURE Children, 107 in number, aged 1.3-17.3 years, were studied at Day 1 of induction therapy according to the current Nordic protocol. Five infants, 3-9 months old, were also included. Plasma samples were drawn 23 hr after the start of a 24-hr infusion of doxorubicin 40 mg/m(2), and analyzed by reversed-phase liquid chromatography. RESULTS There was a more than 10-fold difference between patients in dose normalized plasma concentration of doxorubicin, median 62.8 ng/ml, range 22.6-334 ng/ml. The doxorubicin concentrations differed significantly between age groups (P = 0.003). Children aged 4-6 years had the highest doxorubicin concentrations, median 77.9 ng/ml, followed by 2-4-year-old children, median 64.3 ng/ml. Both younger and older children had median values of about 50 ng/ml. Patients with white blood cell (WBC) count > 50 x 10(9)/L at diagnosis had significantly lower doxorubicin concentrations, median 55.3 ng/ml, than those with WBC count < 10 x 10(9)/L, median 64.4 ng/ml (P = 0.015). There was no difference in doxorubicin concentration between boys and girls. No correlation was found between doxorubicin levels and serum aminotransferases or serum creatinine. The concentration of doxorubicinol was 13% (median value) of that of doxorubicin. Four infants, 7-9 months old, had plasma clearance between 350-431 ml/min/m(2), which is in the same range as in older children. A 3-month-old infant had a clearance of 181 ml/min/m(2). CONCLUSIONS The age groups who had the highest doxorubicin concentrations, (2-) 4-6-year-old children, are known to make up a large proportion of standard risk ALL cases with good prognosis. The correlation between doxorubicin plasma levels and clinical effect needs further study. The influence of age, body composition, and tumor burden on the pharmacokinetics of antineoplastic drugs should also be further explored, aiming at improvements in the current dosing regimen based on BSA.

Abstract
Capillary electrophoresis with laser-induced fluorescence detection was used to separate and detect doxorubicin and at least five metabolites from NS-1 cells that were treated with 25 microM doxorubicin for 8 h. Using 10 mM borate, 10 mM sodium dodecyl sulfate (pH 9.3) as separation buffer, the 488-nm argon-ion laser line for fluorescence excitation, and a 635 +/- 27.5 nm bandpass filter for detection, the limit of detection (S/N=3) for doxorubicin is 61 +/- 13 zmol. This low limit of detection allows for the detection of a larger number of metabolites than previously reported. Two extraction procedures were performed: a bulk liquid-liquid extraction and an in-capillary single-cell lysis. While in the bulk liquid-liquid extraction procedure, recovery for doxorubicin range from 50 to 99%, in single cell analysis the recovery is expected to be complete. Furthermore performing lysis of a single cell inside the separation capillary prevents doxorubicin or metabolite loss or degradation during handling. Based on the bulk method the calculated metabolite abundance is in the sub-amol per cell range while it varies from 0.1 to 1.1 fmol per cell in single cell analysis confirming metabolite loss during handling. Each metabolite was found at a level less than 0.1% of the doxorubicin content in either method, suggesting a slow metabolism in the NS-1 cell system or effective removal of metabolites by the cell.

Abstract
Laser-induced fluorescence (LIF) detection is now a well-known sensitive and selective detection mode for capillary electrophoresis (CE) analysis. It has been shown to be 100- to 100,000-times more sensitive than UV detection and little work has been done using LIF in conjunction with high-performance liquid chromatography (HPLC). The need for greater resolution and higher sensitivity for the analysis of anthracyclines (fluorescent chemotherapic drugs), prompted us to compare CE-LIF and HPLC-LIF, for the detection of these substances. CE-LIF sensitivity based on quantity of anthracycline injected is 50-times greater than that obtained with HPLC-LIF, because of the injected sample volume. Analysis of daunorubicin in Kaposy sarcoma tumors and in plasma are presented. The decrease of the concentration of daunorubicin in the tumor and in the plasma following time show the same behavior, indicating identical concentrations of the anthracycline in both samples.

Abstract
Thirty cases (breast cancer-20 cases, malignant lymphoma-4 cases, different malignancies-6 cases) of histologically/cytologically verified malignant pleural effusion (MPE) in 29 patients were treated with intrapleurally instilled mitoxantrone (30 mg). The therapy was well tolerated. At evaluation, 25 patients had died of progressive disease. The median survival was 3 months (range 0.3-21.3 months). There were 26 responders (12 complete responses (CR), 14 partial responses (PR)), whereas 4 patients relapsed and 3 of these had an early relapse (within 3 months). Patients achieving PR or CR had a low risk (15%) of treatment failure. Five patients were subjected to a pharmacokinetic evaluation. This demonstrated rapidly declining plasma and pleural exudate levels of mitoxantrone within the first 6 hours. At 24 hours after instillation, mitoxantrone was only detected in circulating mononuclear cells. This study shows that mitoxantrone is efficacious in the treatment of MPE, and may represent a cost-effective alternative.

Abstract
Subclones of the two well-characterized myeloid cell lines HL-60 and KG1a were selected for doxorubicin resistance by systematic exposure to increased concentrations of the drug in vitro. Both subclones demonstrated a threefold increased resistance to the drug as evident from cell growth in liquid culture and clonogenicity in a semisolid matrix. Both resistant subclones displayed a similar degree of reduced total and nuclear doxorubicin levels. The HL-60 and the KG1a cells differed qualitatively and quantitatively with respect to glutathione (GSH) levels during culture, with markedly elevated concentrations in the resistant HL-60 subclone during 1 week of culture. Total GSH pools in resistant and sensitive KG1a cells were similar, but maximum GSH levels were reached earlier in the resistant KG1a clones than in the parental cells. Northern blot analysis suggests that resistance was accompanied by increased mdr1 expression in the KG1a but not in the HL-60 cells, whereas alterations in the glutathione S-transferase P1-1 and topoisomerase II message was evident in the latter. The results demonstrate the complex, multifactorial mechanisms behind the in vitro induction of even moderate resistance in anthracyclines.
