Objective To evaluate the effect of TILs treatment on postoperative patients with hepatocellular carcinoma (HCC) and the in vitro and in vivo hepatic targeting tendency of a compound of Galactosyl-Anti-CD_3McAb-TILs.Methods Thirty postoperative HCC patients were treated with TILs plus rIL-2. A hepatic targeting carrier, Galactosyl-Anti-mouse-CD_3-monoclonal antibody (Gal-Anti-CD_3-McAb), was synthesized.Result It was found that the peripheral blood level of IL-2 and T cell subset increased in all the 30 patients treated by TILs.24 HCC cases undergoing hepatectomy were treated by TILs therapy, and follow-up of 6 to 48 months found no recurrence. In an murine experiment a combination of TIL & Galactosyl-Anti-CD_3McAb-TIL tended to aggregate in lung while infused from peripheral vein. Its hepatic targeting tendency was unremarkable. Conclusion Postoperative use of TILs increased patients’ antitumor immunity, prolongs the survival, while galactosyl-anti-CD_3McAb-TIL does not show a satisfactory hepatic target tendency.

OBJECTIVETo evaluate the outcomes of T3a prostate cancer with unfavorable prognostic factors treated with permanent interstitial brachytherapy combined with external radiotherapy and hormone therapy.
METHODSFrom January 2003 to December 2008, 38 patients classified as T3a prostate cancer with unfavorable prognostic factors were treated with trimodality therapy (brachytherapy + external radiotherapy + hormone therapy). The prescription dose of brachytherapy and external radiotherapy were 110 Gy and 45 Gy, respectively. The duration of hormone therapy was 2-3 years. The endpoints of this study included biochemical failure-free survival (BFFS), distant metastasis-free survival (DMFS), cancer-specific survival (CSS), and overall survival (OS). Survival curves were calculated using the Kaplan-Meier method. The Log-rank test was used to identify the prognostic predictors for univariate analysis.
RESULTSThe median follow-up was 71 months. The serum pre-treatment prostate-specific antigen (PSA) level ranged from 10.0 to 99.8 ng/ml (mean 56.3 ng/ml), the Gleason score ranged from 5 to 9 (median 8), and the percentage of positive biopsy cores ranged from 10% to 100% (mean 65%). The 5-year BFFS, DMFS, CSS, and OS rates were 44%, 69%, 82%, and 76%, respectively. All biochemical failures occurred within 40 months. The percentage of positive biopsy cores was significantly correlated with BFFS, DMFS, and OS (all P=0.000), and the Gleason score with DMFS (P=0.000) and OS (P=0.001).
CONCLUSIONST3a prostate cancer with unfavorable prognostic factors presents not so optimistic outcome. Hormone therapy should be applied to prolong the biochemical progression-free or metastasis-free survival. The percentage of positive biopsy cores and the Gleason score are significant prognostic factors.
