Abstract
e15558 Background: We evaluated safety and efficacy of concurrent chemoradiotherapy (CCRT) with capecitabine in patients with locally advanced pancreatic cancer (LAPC). We also tried to devise a prognostic model for LAPC undergoing definitive CCRT. Methods: Between January 2004 and January 2008, 39 patients with LAPC treated with capecitabine CCRT were reviewed. Capecitabine was administered at 850 mg/m2 bid every day for 5 weeks. Radiotherapy was given 5 days per week, at 1.8 Gy fractions, over the 5 weeks. Results: Thirty seven (94.8%) patients completed CCRT, and 2 patients removed during the treatment for toxicity issues. Of the 36 evaluable patients, 15 (41.7 %) patients achieved partial response, and 13 (36.1 %) had a stable disease with 77.8% of disease control rate. Among the 28 patients who had achieved disease control after CCRT, 8 patients (21.6 %) received gemcitabine-based post-CCRT chemotherapy without dose reduction or delay. With median 1.8 years of follow- up, the overall survival was 14.3 months (95% confidence interval [CI]; 10.6–17.9 months). Median progression free survival was 11.1 (95% CI 7.2–15.1) for all patients, and 7.9 months (95% CI 6.6–9.2) for those not received post-CCRT chemotherapy. No patient had grade 4 hematologic or non-hematologic toxicity. Eight patients (21.6%) had severe grade 3 toxicities, 7 (18.9%) with gastrointestinal toxicity and 1 (2.7%) with hematologic toxicity. Prognostic factors for survival were serum albumin (P=0.014; relative risk [RR], 3.4; 95% CI, 1.4, 8.6), and adjuvant gemcitabine treatment (P = 0.005; RR, 3.5; 95% CI, 1.2, 10.6). The prognostic grouping resulted in three groups with significantly different prognosis: group 1 (0 adverse factor; n=8; 1-year survival, 87.5%), group 2 (1 adverse factor; n=23; 1-year survival, 52.9%) and group 3 (2 adverse factors; n=8; 1-year survival, 25.0%). Conclusions: Combined therapy with capecitabine CCRT was well tolerated. Capecitabine seems to be a promising regimen in the treatment of LAPC, in terms of response, survival, and tolerable adverse effects. No significant financial relationships to disclose.

Abstract
4537 Background: Although the adjuvant chemoradiation therapy has gained popularity and has become the standard of care in patients with resected gastric cancer in U.S., the role of chemoradiation therapy after extended D2 dissection has been questioned. We conducted a phase III trial to compare capecitabine/cisplatin (XP) vs XP + radiotherapy (RT) in curatively D2 resected gastric cancer patients in terms of disease free survival and overall survival. Methods: Eligibility criteria were as follows: stage Ib (T1N1, T2bN0) - IV (M1 excluded), curatively ≥ D2 resected gastric adenocarcinoma. XP only: X 2,000 mg/m2/d D1∼14, CDDP 60 mg/m2 D1 repeated every 3 weeks, 6 cycles; XP + RT: X 2,000 mg/m2/d D1∼14, CDDP 60 mg/m2 D1 x 2 cycles ⋄ RT 45 Gy (25 fractions) + X 1,650 mg/m2/d during RT ⋄ X 2,000 mg/m2/d D1∼14, CDDP 60 mg/m2 D1 x 2 cycles. The primary endpoint is 3-year disease-free survival. Results: From October 2004 to April 2008, 458 patients (XP arm: 228 patients; XP/RT arm: 230 patients) were enrolled. In XP arm, 172 (75%) of 228 enrolled patients completed 6 cycles of chemotherapy. In XP + RT arm, 188 (82%) of 230 patients completed the full course of XP 2 cycles - X + RT - XP 2 cycles. Conclusions: Safety and feasibility analysis of the two arms will be reported at the meeting. No significant financial relationships to disclose.

Abstract
We assessed heterologous protein expression in 64 strains obtained from the Escherichia coli Reference (ECOR) collection, a collection representing diverse natural E. coli populations. A plasmid generating a glutathione S-transferase and plant carbonic anhydrase fusion protein (GST-CA) under the control of the tac promoter was introduced into the ECOR strains, and the quantity of the fusion protein was determined by SDS-PAGE. The foreign protein was generated at various levels, from very high (40 strains, high producers) to very low (six strains, low producers). Immunoblotting showed that the high producers expressed approximately 250-500 times more GST-CA protein than the low producers. The results of semi-quantitative RT-PCR showed that the low producers generated mRNA levels comparable to those of the high producers, thereby suggesting that, at least in this case, inefficient translation is a major cause of the low production. We introduced a different plasmid, which expressed a maltose binding protein and plant guanylate kinase fusion protein (MBP-GK) into the six low producers. Interestingly, five of these expressed MBP-GK at very high levels. Thus, we conclude that the production of a particular protein from an expression vector can vary considerably, depending on the host strain. Strains in the ECOR collection could function as useful alternative hosts when a desired level of protein expression is not obtained from commonly used strains, such as E. coli K12 or B derivatives.

Abstract
In this study, we describe the development of a simple and efficient method for cell lysis via the insertion of a bacteriophage lambda lysis gene cluster into the pET22b expression vector in the following order; the T7 promoter, a gene for a target protein intended for production, Sam7 and R. This insertion of R and Sam7 into pET22b exerted no detrimental effects on cellular growth or the production of a target protein. The induction of the T7 promoter did not in itself result in the autolysis of cells in culture but the harvested cells were readily broken by freezing and thawing. We compared the efficiency of the cell lysis technique by freezing and thawing to that observed with sonication, and determined that both methods completely disintegrated the cells and released proteins into the solution. With our modification of pET22b, the lysis of cells became quite simple, efficient, and reliable. This strategy may prove useful for a broad variety of applications, particularly in experiments requiring extensive cell breakage, including library screening and culture condition exploration, in addition to protein purification.

Abstract
11502 Background: MBC patients (pts) have a median survival of 27 mo. Vorinostat is a small molecule inhibitor of histone deacetylase that exerts its targeted action during post-translational acetylation of core nucleosomal histones, affecting chromatin structure, thereby regulating genes implicated in cell survival, proliferation, differentiation, and apoptosis. The primary end point was to evaluate the response rate. Secondary endpoints included: time to progression, overall survival, toxicity, and assessment of biologic correlates. Method: From 6/05 to 3/06, we enrolled 14 pts with measurable MBC. Response and progression were evaluated using RECIST criteria. Two pts had no, 5 pts had one, and 7 pts had two prior regimens. Median age was 60.5 years (37- 89). Six were ER/PR positive, four were Her2neu overexpressers. Sites of metastatic disease included brain (1), liver, lungs, and bone (5), pelvic and chest wall (1), liver and bone (2), distant lymph nodes (3), pleura and bone (1). Pts received Vorinostat 200mg oral twice daily for 14 of 21 days per cycle. Tumor measurements were performed after every 2 cycles. Biopsies (pre and on-treatment) were collected from 6 of 14 pts. Results: The mean cycles delivered was 5 (range: 1–18). Four pts had SD for a median of >8.7 mo (4–13 mo); 1 pt with ER/PR/Her2neu negative tumor who received no prior treatment for MBC to mediastinal nodes and chest wall continues to receive treatment having completed cycle 18 with stable disease for >11.4 mo. The median duration on treatment for all pts is 3.2 mo (1–12 mo). Toxicities included gr 3 fatigue (1), gr 2–3 diarrhea (3), gr 2–3 nausea (2), gr 2 mucositis(1), gr 4 lymphopenia (1), gr 2–3 lymphopenia (6). Correlative studies of pre- and on-treatment tumor samples will be presented describing gene expression profiling using custom Agilent oligonucleotide microarrays optimized for analysis of RNA isolated from formalin fixed paraffin embedded tissues (FFPET). Conclusion: In this trial Vorinostat demonstrated disease stabilization rate in 4/14 (29%) pts by intention to treat analysis. With ease of administration, further investigation in combination with other agents is warranted. (NCI-NO1-CM- 62209) No significant financial relationships to disclose.

Abstract
The present study investigates how loading of the shoulder effect the formation of the trabeculae in the subarticular region of the gleno-humeral joint. Bone morphology was determined from scapular cadaveric specimens and finite element (FE) analysis was employed to analyse principal stress trajectories. Boundary conditions corresponded to five functional activities were considered. The results show deviations of the computed trajectories from actual trabecular lines obtained from the bone specimens ranged on average from 10% to 17%. Each activity produced different regional deviation corresponding to the specific loading condition. This study concludes that certain loading conditions are more significant in explaining the formation of the trabecular architecture. The results also suggest that due to the extra sensitivity of the front and the rear aspects of the "lateral region" to the loading conditions, these regions may be more indicative in reflecting shoulder injuries.
