OBJECTIVETo investigate whether bortezomib can enhance the sensitivity of human prostate cancer (PCa) cells to natural killer (NK) cell-mediated cytotoxicity, and whether it produces the same effect on different PCa cell lines.

METHODSWe treated androgen-dependent PCa LNCaP cells and androgen-independent PCa DU145 cells with bortezomib at the concentrations of 0, 5, 10, 15, 20 and 25 nmol/L for 24, 48 and 72 hours, and then detected the proliferation and apoptosis of the tumor cells by CCK-8 and Annexin V/PI, respectively.

RESULTSThe proliferation rates of the DU145 cells treated with 15, 20 and 25 nmol/L bortezomib were (82.79 +/-2.04)%, (73.59+/- 2.95)% and (74.16+/- 6. 16)% at 48 hours and (71.24+/- 5.30)%, (51.20+/- 2.91)% and (38.02+/- 2.67)% at 72 hours, and those of the LNCaP cells were (77.04+/- 7.74)% , (42.61 +/- 6.62)% and (23.85 +/-6.04)% at 48 hours and (36.45 +/-7.02)%, (14.94 +/-5.76)% and (11.65 +/-5. 87)% at 72 hours, both significantly inhibited as compared with the control group (P <0.05). At 24 hours, the apoptosis rates of the DU145 cells treated with 15, 20 and 25 nmol/L bortezomib were (14.41 +/- 1.32)% , (16.13 +/- 1.55)% and (14.48 +/- 1.42)% , and those of the LNCaP cells treated with 20 and 25 nmol/L bortezomib were (12.77 +/- 1.28)% and (14. 84 +/- 1.65)% , significantly higher than those of the control group (P <0.05) , and the DU145 cells showed an even higher sensitivity to bortezomib than the LNCaP cells. Bortezomib failed to sensitize these two cell lines to NK cell-mediated cytotoxicity in short-term assay, while long-term assay manifested that the apoptosis rates of DU145 and LNCaP cells after treated with 20 nmol/L bortezomib + NK cells were (41.83 +/- 5.06)% and (30.31 +/- 3.62)% , respectively, significantly higher

CONCLUSIONBortezomib enhances the sensitivity of than those after treated with either bortezomib or NK cells alone (P <0.05). PCa cells to NK cell-mediated cytotoxicity and adds to the effect of current cancer therapies, and it is more efficacious for androgen-independent prostate cancer.

Objective To investigate the surrounding and central dosimetric distribution difference of the same activity, same number of 125I seeds. Methods 3D treatment planning system (3D-TPS) was used to separately sketch out 7 cubes with side length of 2 cm, 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm and 5 cm;simulations of different tumor sizes were established, into which 125I seeds with activity of 0.5 mCi were respectively loaded. All seeds were distributed at the periphery of the tumor (peripheral group) with the prescribed dose of 145 Gy. The dose volume histogram (DVH) was printed and the 90% of target volume absorbed dose (D90), 90% of prescription dose coverage target volume percentage (V90), the maximum dose and mean dose were determined. Then the seeds in every cube were distributed into the center (central group) and the above parameters were calculated by using the same method. Results The mean D90 of the peripheral and central group was (147.29 ±0.58) Gy and (106.08 ±9.40) Gy respectively, the difference between the two groups was statistically significant (t=-4.292, P=0.005). The mean V90 of the peripheral and central group was (95.46±0.44)% and (79.07±4.19)% respectively, the difference between the two groups was statistically significant (t=-3.831, P=0.009). The mean maximum dose of the peripheral and central group was (1 224.65 ±12.7) Gy and (1 532.48 ±48.54) Gy respectively, the difference between the two groups was statistically significant (t=6.823, P=0.000). The mean value of average dose of the peripheral and central group was (192.14 ±2.89) Gy and (179.81 ±5.40) Gy respectively, the difference between the two groups was statistically significant (t=-2.847, P=0.029). Conclusion The dose distribution is directly influenced by the distribution pattern of the 125I seeds. When the number and activity of the 125I seeds are the same, the peripheral seeds implantation has a better dose distribution.

Objective To explore the dosimetric effects of the same number and activity of radioactive 125I seeds in different plane arrangements. Methods Simulated 9 distribution modes using 9 125I seeds were designed by three- dimensional treatment planning system (3D- TPS), and the isodose curves of 60 Gy, 80Gy, 130 Gy, 145 Gy and 200 Gy were obtained. The areas enclosed by the isodose curves, the longer and shorter radius of these isodose curves and the medical cost per unit area were calculated with the professional image analysis software. Results Obvious differences in areas enclosed by the isodose curves, the longer and shorter radius of these isodose curves and the medical cost per unit area existed between each other among the nine different distribution modes of 9 125I seeds. The distribution modes that had the maximum areas enclosed by 60 Gy, 80 Gy, 130 Gy, 145 Gy and 200 Gy isodose curves were x1.5y1.5, x1y1.5, x1y1, x1y1 and x0.5y1, respectively, with the corresponding areas of 1 583.86 mm2, 1 146.03 mm2, 768.30 mm2, 621.85 mm2 and 480.97 mm2, respectively. Conclusion The peripheral dose and the therapeutic efficacy are significantly influenced by the arrangement of 125I seeds when the same number and activity of the seeds are used. The dose distributions are more homogeneous when the maximum areas enclosed by the isodose curves are obtained.

Objective To investigate the dose distribution of esophageal stents carrying different diameters of radioactive 125I seeds in tumor target area. Methods A laser scanner was used to scan a piece of blank paper on which circles of 12 mm, 14 mm and 16 mm diameter and a 5 cm scale were drawn. The data were stored in JPEF format on the computer desktop. According to the circular diameter, simulations of the corresponding esophageal stents were established, which were divided into group A, group B and group C. By using image conversion program, 17 images with 5 mm slice-distance were created for each group; the images were transmitted to the computer treatment planning system (TPS) to simulate the 8 cm long esophageal stents of different diameters. TPS was used to sketch the gross tumor volume (GTV) in order to simulate the esophageal stent border that was used as the inner boundary of GTV, which was expanded 0.5 cm outward to be used as the external boundary of GTV. Beginning from the fifth level, the 4 cm-long GTV was drawn with circles. Setting the same prescription dose, from the fifth level to the thirteenth level the 125I seeds with 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9 mCi were successively loaded on the simulation of the esophageal stents. The distance between 125I seed layers was 1 cm; the average number of seeds distributed on each layer was 4 particles. The dose volume histogram (DVH) was obtained. The D90 (the dose received by 90% of the target) and V90 (the percentage of the GTV volume receiving 90% the prescription dose) were recorded.Result s The arithmetic mean D90 of group A, B and C was (77.24 ±19.92) Gy, (69.56 ±25.27) Gy and (56.38±20.08) Gy respectively, and no statistically significant differences existed between each other among the three groups (F=0.84,P=0.44). The V90 of group A, B and C was (77.76±30.73)%,(76.79±25.92)%and (64.10 ±32.49)% respectively, and no statistically significant differences existed between each other among the three groups (F=0.46,P=0.64). Conclusion When the diameter of radioactive esophageal stent is 12 mm, the activity of 125I seed of 0.6 mCi is recommended. When the diameter of radioactive esophageal stent is 14 mm or 16 mm, the activity of 125I seed of 0.7 mCi is recommended. Nevertheless, when the diameter of radioactive esophageal stent is 16 mm, distribution of every five 125I seeds on each layer is strongly recommended. These three kinds of esophageal stent diameter have no significant effect on the dosimetric parameters.
