Cutaneous metastases originating from an internal cancer are relatively uncommon in clinical practice, and metastatic lesions to the breast are rarer than those to the skin. Skin metastases of lung cancer, which may be the first sign of the disease, usually indicate progressive disease and a poor prognosis. We describe a 47-year-old male who presented with recurring masses in the lumbar region bilaterally and the right breast. Immunohistochemical findings and radiological imaging suggested lung cancer. This is the first reported case of small cell lung cancer metastasizing to two separate, uncommon sites, the skin and breast.

This study was aimed to shed light on the biological and pharmaceutical characterization of the complexes of FUS1/hIL-12 double gene with cationic liposome, and to assess such complexes' transfection efficiency, stability and cytotoxicity; for they have the potential for use as drugs in gene therapy of lung cancer. Gel retardation assay, diameter measurement, and surface charge by photon correlation spectroscopy (PCS) were employed to select the appropriate ratio of "cationic liposome to DNA" of the double-gene and liposome complexes. The plasmid EGFP and plasmid PVITO2-hIL12-FUS1 mediated by cationic liposome were transfected into A549 lung cancer cells respectively, and the expression levels of EGFP and FUS1 and hIL-12 were determined by inverted fluorescence microscope and immunohistochemical and enzyme linked immunosorbent assay (ELISA) respectively. Agarose gel electrophoresis was performed to detect the stability of the double-gene and liposome complexes, after they were incubated with serum and Dnase I respectively. After the erythrocytes being incubated with the complexes of FUS1/hIL-12 with cationic liposome, the morphology of erythrocyte was observed by microscopy. The result of this study provides a basis for the use of the complexes of FUS1/hIL-12 with cationic liposome in gene therapy of lung cancer.

OBJECTIVETo evaluate the effectiveness and safety of large dose compound Sophora flavescens Ait injection in the treatment of advanced malignant tumors.

METHODSA non-randomized case control trial was conducted. Ninety six patients with pathologically confirmed advanced non-small-cell lung cancer, gastric cancer and colorectal cancer were divided into traditional Chinese medicine group and chemotherapy group, 48 cases each. Patients of the traditional Chinese medicine group received treatment with large dose of compound Sophora flavescens Ait injection (20 ml/d), and 21 days as a cycle.

RESULTSForty-seven patients of the traditional Chinese medicine group and 46 patients of the chemotherapy group completed their treatment, respectively. The clinical benefit rate (CBR) in the traditional Chinese medicine group was 83.0%, significantly higher than that in the chemotherapy group (69.6%) (P < 0.01). The Karnofsky performance status and weight improvement in the traditional Chinese medicine group was superior to that in the chemotherapy group (P < 0.05). Except the skin irritation in one patient in the traditional Chinese medicine group, there were no other clinical adverse effects related with the large dose compound Sophora flavescens Ait injection.

CONCLUSIONSLarge dose compound Sophora flavescens Ait injection in the treatment of advanced malignant tumors is safe and effective. The recommended dose is 20 ml/d.

OBJECTIVETo study Chinese medicine (CM) signs and symptoms of urethane-induced lung cancer in mice, and observe the effect of Aconiti Lateralis Radix Praeparata and Taraxaci Herba on symptoms in mice and tumor progress.

METHODThe mice were intraperitoneally injected with urethane twice a week for consecutively five weeks to establish a lung cancer model. The changes in their appearance, body temperature and auricle microcirculation were observed in carcinogenic process. CM signs and symptoms of urethane-induced lung cancer in mice were evaluated with energy metabolism, erythrocytic ATP emzymatic activity and hemorrheological index. During the tumor model was induced, Aconiti Lateralis Radix Praeparata and Taraxaci Herba were used to treat the mice and observe their effect on symptoms in mice and tumor progress.

RESULTDuring urethane was used to induce lung cancer, the mice had gradually become chill, lazy, hunched, with reduction in temperature, cyanosis in auricle and tail. Meanwhile, their energy metabolism and erythrocytic ATP enzymatic activity reduced, whereas their whole blood viscosity and erythrocytic aggregate index increased. Taraxaci Herba showed an effect on enhancing above symptoms and signs but had no effect on tumor progress. Aconiti Lateralis Radix Praeparata showed an effect on reducing above symptoms and signs and preventing tumor progress.

CONCLUSIONMice with urethane-induced lung cancer show CM signs and symptoms of congealing cold with blood stasis. The treatment with Aconiti Lateralis Radix Praeparata can alleviate symptoms and signs in mice and prevent tumor progress.

OBJECTIVETo observe the effect of alcohol extracts from Pharbitidis Semen on the proliferation and metastasis of Lewis lung cancer, and study its anti-tumor mechanism.

METHODIn vitro, MTT assay and scratch assay were adopted to detect the effect of alcohol extracts from Pharbitidis Semen on the proliferation and metastasis of Lewis lung cancer cells. The cell autophagy was detected by the acridine orange staining. The gap-junction intercellular communication (GJIC) was investigated by the fluorescent yellow transfer. The expression of aquaporin 1 (AQP1) was analyzed by the Western blotting. In vivo, the subcutaneous implant model and the experimental pulmonary metastasis model of Lewis lung cancer in mice were established to evaluate the anti-tumor and anti-metastasis effects of alcohol extract from Pharbitidis Semen. The serum carcinoembryonic antigen (CEA) and beta2 microglobulin (beta2-MG) of mice bearing Lewis lung cancer were detected by the electrochemiluminesence immunoassay. The expressions of lung AQP1 and Connexin 43 (Cx43) were examined by the immunohistochemical method.

RESULTIn vitro, alcohol extracts from Pharbitidis Semen inhibited the cell proliferation in a dose-dependent matter, significantly prevented the cell migration, down-regulated AQP1 proteins of cells, promoted GJIC, and decreased the serum-free autophagy of tumor cells. In vivo, compared with untreated model mice, alcohol extracts from Pharbitidis Semen inhibited the tumor growth in a dose-dependent matter, prevented the tumor metastasis and prolonged the life span of mice bearing Lewis lung cancer, while decreasing serum CEA and beta2-MG of mice bearing Lewis lung cancer, enhancing the immumohistochemical staining intensity of Cx43 and weakening aquaporins AQP1 positive intensity.

CONCLUSIONAlcohol extracts from Pharbitidis Semen could prevent the proliferation and metastasis in Lewis lung cancer cells. Its mechanism may be related to the promotion of GJIC and the down-regulation of AQP1.

UNLABELLEDObjective To evaluate the efficacy of 99mTc-labeled C2A probe in detection of apoptosis of non-small cell lung cancer (NSCLC) cells after chemotherapy.

METHODSImaging studies were performed in NSCLC H460-bearing mice. The mice were divided into 2 groups: the paclitaxel-treated group and control group. 99mTc-C2A was injected intravenously at 12, 24, 48 and 72 h after chemotherapy. Images were acquired at 3 h and 6 h after injection using a pinhole collimator. The regions of interest (ROI) were drawn in tumor area and contralateral nomal tissue, and the ratio of T/NT were caculated. The tumor sections were stained by HE and TUNEL (terminal deoxynucleotidyltransferase-mediated dUTP-nick-end labeling) staining to confirm the presence of apoptosis. Activated caspase-3 was also analyzed with flow cytometry.

RESULTSLittle uptake of 99mTc-C2A was found in baseline images, but tumor uptake increased very much after chemotherapy, the T/NT ratio was 1.79 +/- 0.34, 2.23 +/- 0.33 and 2.78 +/- 0.34, respectively. The T/NT ratio of control was 1.48 +/- 0.23. Tumor uptake (% ID/g) of 99mTc-C2A in chemotherapy groups were 2.82 +/- 0.90, 3.13 +/- 0.48 and 3.52 +/- 1.18, respectively. Tumor uptake (% ID/g) in the control group was 1.21 +/- 0.51. It in paclitaxel-treatment groups were 2.82 +/- 0.90, 3.13 +/- 0.48 and 3.51 +/- 1.18, respectively, significantly higher than that in untreated mice. Furthermore, the uptake of 99mTc-C2A correlated well with apoptotic index (r = 0.56, P < 0.01), and activated caspase-3 (r = 0.59, P < 0.01).

CONCLUSIONOur preliminary results demonstrated that 99mTc-C2A imaging in vivo for detection of cell death in solid tumors is feasible and well correlated with TUNEL staining and activated caspase-3. The C2A holds promise and warrants further development as a molecular probe to early predict cancer treatment efficacy.
