Assessment of Early Tumor Response to Cytotoxic Chemotherapy with Dynamic Contrast-Enhanced Ultrasound in Human Breast Cancer Xenografts

There is a strong need to assess early tumor response to chemotherapy in order to avoid adverse effects from unnecessary chemotherapy and allow early transition to second-line therapy. This study was to quantify tumor perfusion changes with dynamic contrast-enhanced ultrasound (CEUS) in the evaluation of early tumor response to cytotoxic chemotherapy. Sixty nude mice bearing with MCF-7 breast cancer were administrated with either adriamycin or sterile saline. CEUS was performed on days 0, 2, 4 and 6 of the treatment, in which time-signal intensity (SI) curves were obtained from the intratumoral and depth-matched liver parenchyma. Four perfusion parameters including peak enhancement (PE), area under the curve of wash-in (WiAUC), wash-in rate (WiR) and wash-in perfusion index (WiPI) were calculated from perfusion curves and normalized with respect to perfusion of adjacent liver parenchyma. Histopathological analysis was conducted to evaluate tumor perfusion, tumor cell density, microvascular density (MVD) and proliferating cell density. Significant decreases of tumor normalized perfusion parameters (i.e., nPE, nWiAUC, nWiR and nWiPI) were noticed between adriamycin-treated and control groups (P<0.01) 2 days after therapy. There were significant differences of tumor volumes between control and treated groups on day 6 (P<0.001) while there were no significant differences in tumor volume on days 0, 2 and 4 (P>0.05). Significant decreases of tumor perfusion, tumor cell density, MVD and proliferating cell density were seen in adrianycin-treated group 2 days after therapy when compared to control group (P<0.001). Dynamic CEUS for quantification of tumor perfusion could be used for early detection of cancer response to cytotoxic chemotherapy prior to notable tumor shrinkage.

Heat shock proteins in cancer: diagnostic, prognostic, predictive, and treatment implications

Heat shock proteins (Hsps) are overexpressed in a wide range of human cancers and are implicated in tumor cell proliferation, differentiation, invasion, metastasis, death, and recognition by the immune system. We review the current status of the role of Hsp expression in cancer with special emphasis on the clinical setting. Although Hsp levels are not informative at the diagnostic level, they are useful biomarkers for carcinogenesis in some tissues and signal the degree of differentiation and the aggressiveness of some cancers. In addition, the circulating levels of Hsp and anti-Hsp antibodies in cancer patients may be useful in tumor diagnosis. Furthermore, several Hsp are implicated with the prognosis of specific cancers, most notably Hsp27, whose expression is associated with poor prognosis in gastric, liver, and prostate carcinoma, and osteosarcomas, and Hsp70, which is correlated with poor prognosis in breast, endometrial, uterine cervical, and bladder carcinomas. Increased Hsp expression may also predict the response to some anticancer treatments. For example, Hsp27 and Hsp70 are implicated in resistance to chemotherapy in breast cancer, Hsp27 predicts a poor response to chemotherapy in leukemia patients, whereas Hsp70 expression predicts a better response to chemotherapy in osteosarcomas. Implication of Hsp in tumor progression and response to therapy has led to its successful targeting in therapy by 2 main strategies, including: (1) pharmacological modification of Hsp expression or molecular chaperone activity and (2) use of Hsps in anticancer vaccines, exploiting their ability to act as immunological adjuvants. In conclusion, the present times are of importance for the field of Hsps in cancer, with great contributions to both basic and clinical cancer research.

Effect of radiotherapy and chemoradiotherapy on circulating antioxidant system of human uterine cervical carcinoma

Circulating lipid peroxide, antioxidant components and the activities of defense enzymes were estimated in uterine cervical carcinoma patients (before and after radiotherapy and radiotherapy combined chemotherapy) and compared with controls. Some of the antioxidant components such as glutathione, vitamin E and selenium are reduced in cervical cancer. The reduced levels of vitamin E and glutathione were normalized after treatment. Erythrocyte lipid peroxide (E-LPx) and erythrocyte membrane lipid peroxide (EM-LPx) levels were found to be increased in all the stages of uterine cervical carcinoma. The important antioxidant enzymes such as erythrocyte superoxide dismutase (E-SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione-S-transferase (GST) and glucose-6-phosphate dehydrogenase (G6PDH) were found to be decreased in uterine cervical carcinoma. These altered biochemical parameters were reversed to normal, of course with varied degree after different mode of therapy. Significant normalization was observed in Type 11 chemoradiotherapy.

Hyperthermic isolated limb perfusion increases circulating levels of inflammatory cytokines

Hyperthermic isolated limb perfusion is an established method of treatment for regionally advanced melanoma. Recent studies suggest that exogenously administered cytokines potentiate tumor response in patients with in-transit melanoma. We hypothesized that isolated limb perfusion induces an immunogenic response characterized by increased circulating levels of cytokines in the pump circuit, potentially contributing to the antitumor effect. We obtained blood samples from the perfusion circuit and systemic circulation at various intervals from patients undergoing isolated chemotherapeutic perfusion for melanoma. Samples were analyzed for serum cytokine profiles by enzyme-linked immunosorbent assay. When compared with baseline values, significant increases in serum levels of interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor (TNF) occurred within the perfusion circuit during isolated limb perfusion (P<0.05). In addition, there was a corresponding increase in IL-8 within the systemic circulation at the 60-min interval (P<0.05), suggesting some degree of leakage from the isolated circuit due to the extremely high levels of IL-8 in the perfusion circuit. A transient but insignificant decrease in circulating levels of neutrophils was also observed during the perfusion process, which may be attributed to margination. Increased levels of cytokines IL-6, IL-8, and TNF occurred within the isolated circuit during hyperthermic limb perfusion and may contribute to tumor response seen in patients treated with isolated limb perfusion.Presented at the Annual Meeting of the Society of Surgical Oncology, 17–20 March 1994 Houston, Texas
