    Description / Table of Contents: Leading experts summarize and synthesize the latest discoveries concerning the changes that occur in tumor cells as they develop resistance to anticancer drugs, and suggest new approaches to preventing and overcoming it. The authors review physiological resistance based upon tumor architecture, cellular resistance based on drug transport, epigenetic changes that neutralize or bypass drug cytotoxicity, and genetic changes that alter drug target molecules by decreasing or eliminating drug binding and efficacy. Highlights include new insights into resistance to antiangiogenic therapies, oncogenes and tumor suppressor genes in therapeutic resistance, cancer stem cells, and the development of more effective therapies. There are also new findings on tumor immune escape mechanisms, gene amplification in drug resistance, the molecular determinants of multidrug resistance, and resistance to taxanes and Herceptin.

    Notes: We report the development of a novel radio frequency electron-spin-resonance spectrometer designed to provide measurements with high molar sensitivity and resolution in vivo. Radio frequency (250 MHz) is chosen to obtain good penetration in animal tissue and large aqueous samples with modest sacrifice of sensitivity. The spectrometer has a lumped component resonator and operates in continuous-wave mode. The spectrometer is capable of two-dimensional imaging, and with a modest addition should be capable of three-dimensional imaging. We demonstrate 3-mm spatial resolution for DPPH samples. For 10-ml samples of aqueous nitroxide, we demonstrate sensitivity (normalized to spectral width of 1 G) to 3×10−8-M concentrations and spectral resolution of 0.1 G. Spectra from nitroxide spin label injected into a live mouse are shown.

    Notes: Summary The effects of schedule and sequence on the survival of EMT6 tumor cell and bone marrow (CFU-GM) obtained after treatment using combinations of cyclophosphamide (CTX) and thiotEPA or melphalan (l-PAM) were examined and analyzed by isobologram methodology. On a single-injection schedule, when CTX and thiotEPA were given simultaneously or thiotEPA was given prior to CTX, the result was slightly greater than additive tumor-cell kill. However, when CTX preceded thiotEPA by 4 h, there was less than additive cell kill. When the interval between the administration of the two drugs was 8 h, both sequences of the drugs produced greater than additive tumor-cell kill. Simultaneous administration of CTX and thiotEPA on a multiple-injection schedule resulted in sub-additive tumor-cell kill. On the multiple-injection schedule, extending the interval between injections of CTX and thiotEPA to 4 and 8 h resulted in increasing tumor-cell kill. With the 4- and 8-h intervals, no significant sequence-dependent difference in tumor-cell kill was obtained. The results of CTX andl-PAM combinations paralleled those of CTX and thiotEPA. Bone marrow (CFU-GM) survival was used as a representative normal tissue with which to compare tumor-cell survival after each treatment to obtain a measure of therapeutic effect. The trends for the ratios of bone marrow: tumor cell survival were the same for the treatment sequences of CTX with thiotEPA orl-PAM; however, greater magnitudes of differential tumor-cell kill were obtained with CTXl-PAM combinations. Using this measure, the greatest therapeutic effectiveness was seen with single-dosel-PAM or thiotEPA followed 4 h later by CTX and with CTX given as a single or as multiple doses followed 8 h later byl-PAM or thiotEPA. Such data from tumor-model systems may be useful in the development of more effective alkylating agent regimens for use in the clinic.

    Notes: Abstract Tetrahydrocortisol, β-cyclodextrin tetradecasulfate, and minocycline used alone or in combination are not very cytotoxic toward EMT-6 mouse mammary tumor cells growing in monolayer. Tetrahydrocortisol (100 μM, 24 h) and β-cyclodextrin tetradecasulfate (100 μM, 24 h) protected EMT-6 cells from the cytotoxicity of CDDP, melphalan, 4-hydroperoxycyclophosphamide, BCNU, and X-rays under various conditions of oxygenation and pH. Minocycline (100 μM, 24 h) either had no effect upon or was additive with the antitumor alkylating agents or X-rays in cytotoxic activity toward the EMT-6 cells in culture. The combination of the three modulators either had no effect upon or was to a small degree protective against the cytotoxicity of the antitumor alkylating agents or X-rays. The Lewis lung carcinoma was chosen for primary tumor growth-delay studies and tumor lung-metastases studies. Tetrahydrocortisol and β-cyclodextrin tetradecasulfate were given in a 1:1 molar ratio by continuous infusion over 14 days, and minocycline was given i.p. over 14 days, from day 4 to day 18 post tumor implantation. The combination of tetrahydrocortisol/β-cyclodextrin tetradecasulfate diminished the tumor growth delay induced by CDDP and melphalan and produced modest increases in the tumor growth delay produced by cyclophosphamide and radiation. Minocycline co-treatment increased the tumor growth delay produced by CDDP, melphalan, radiation, bleomycin, and, especially cyclophosphamide, where 4 of 12 animals receiving minocycline (14×5mg/kg, days 4–18) and cyclophosphamide (3×150 mg/kg, days, 7, 9, 11) were long-term survivors. The 3 modulators given in combination produced further increases in tumor growth delay with all of the cytotoxic therapies, and 5 of 12 of the animals treated with the 3-modulator combination and cyclophosphamide were long-term survivors. Although neither tetrahydrocortisol/β-cyclodextrin tetradecasulfate, minocycline, nor the three modulator combination impacted the number of lung metastases, there was a decrease in the number of large lung metastases. Treatment with the cytotoxic therapies alone reduced the number of lung metastases. Addition of the modulators to treatment with the cytotoxic therapies resulted in a further reduction in the number of lung metastases. These results indicate that agents that inhibit the breakdown of the extracellular matrix can be useful additions to the treatment of solid tumors.

    Notes: Abstract The ability of the collagenase inhibitor minocycline and of β-carotene to act as positive modulators of cytotoxic anticancer agents was assessed in vitro and in vivo. Cell-culture studies were conducted using the human SCC-25 squamous carcinoma cell line. Simultaneous exposure of the cells to minocycline and β-carotene or 13-cis-retinoic acid along with cisplatin (CDDP) resulted in a small decrease in the cytotoxicity of the CDDP. The addition of each of the modulator combinations for 1 h or 24 h to treatment with melphalan (L-PAM) or carmustine (BCNU) resulted in greater-than-additive cytotoxicity with each of four regimens. The modulator combinations of minocycline and β-carotene applied for 1 h or 24 h and the modulator combination of munocycline and 13-cis-retinoic acid produced greater-than-additive cytotoxicity at 50 μM 4-hydroperoxycyclophosphamide (4-HC), whereas minocycline and 13-cis-retinoic acid applied for 1 h was antagonistic with 4-HC and the other modulator treatments at low concentrations of 4-HC resulted in subadditive cytotoxicity. The effect of treatment with β-carotene alone and in combination with several different anticancer agents was examined in two murine solid tumors, the FSaII fibrosarcoma and the SCC VII carcinoma. Administration of the modulators alone or in combination did not alter the growth of either tumor. Whereas increases in tumor growth delay occurred with the antitumor alkylating agents and β-carotene and with minocycline and β-carotene, a diminution in tumor growth delay was produced by 5-fluorouracil in the presence of these modulators. The modulator combination also resulted in increased tumor growth delay with Adriamycin and etoposide. Tumor-cell survival assay showed increased killing of FSaII tumor cells with the modulator combination and melphalan or cyclophosphamide as compared with the drugs alone. These results indicate that further investigation of this modulator strategy is warranted.

    Notes: Abstract CAI (NSC 609974; L651582), a new agent that has demonstrated antimetastatic activity in vitro and in vivo, was not very cytotoxic toward EMT-6 mouse mammary carcinoma cells in culture or toward FSaIIC fibrosarcoma cells in vivo. Coexposure of EMT-6 cells to CAI and antitumor alkylating agents under various environmental conditions did not markedly increase the cytotoxicity of cisplatin (CDDP), melphalan, or carmustine (BCNU). However, the combination of CAI and 4-hydroperoxycyclophosphamide (4-HC) produced much greater than additive killing of EMT-6 cells. CAI also increased the sensitivity of hypoxic EMT-6 cells to X-rays. CAI increased the cytotoxicity of cyclophosphamide toward FSaIIC tumor cells when animals were treated with single doses of both drugs. The effect of CAI on tumor cell killing by cyclophosphamide was greatest at high doses of the antitumor alkylating agent. CAI administration appeared to result in increased serum levels of prostaglandin E2 and leukotriene B4 in animals bearing the Lewis lung tumor. Administration of CAI on days 4–18 did not alter the growth of the Lewis lung carcinoma but did result in an increase in the tumor-growth delay produced by treatment with CDDP, cyclophosphamide, melphalan, BCNU, and fractionated radiation. Although CAI did not reduce the number of lung metastases present in Lewis lung carcinoma-bearing mice on day 20, it did appear to reduce the number of large (vascularized) metastases present on that day.
