Abstract
UNLABELLED Adverse effects on the soft tissues after Le Fort I osteotomies include: broadening of the alar base, loss of vermilion show of the upper lip and down sloping of the commissures. In theory, an alar cinch suture combined with a muco-musculo-periosteal V-Y closure (ACVY) should improve not only the nasal width, but would also improve the dynamics of some of the mimic muscles. To test the validity of this hypothesis, a prospective study was set up including 22 patients, using standardized full facial frontal photographs, taken immediately preoperatively and 18 months postoperatively. Sets containing three pictures were made: soft tissue in repose, maximum closed mouth smile and maximum smile. The landmarks, alare, crista philtri and cheilion were analysed. The preliminary results show that ACVY-closure does significantly improve the horizontal movement of cheilion with both maximum closed mouth smile and maximum smile, as well as the vertical movement of crista philtri with maximum closed mouth smile. CONCLUSION The Le Fort I osteotomy with ACVY improves the orofacial dynamics.

Abstract
530 Background: Predicting which patients will have ≥4 +LN and may need radiation therapy affects immediate breast reconstruction. We hypothesized that model s to predict the likelihood of ≥4+LN may be improved by incorporation of quantitative real time RT-PCR analysis of SLN. Methods: 728 patients were enrolled in 2 prospective studies of the GeneSearch BLN Assay (Veridex LLC) for SLN metastases. 205 (28.2%) were found to have +SLN by hematoxylin-eosin staining. Of these, 115 pts (15.8%) had tumors ≤5 cm in size with >4 total LN removed, forming the cohort of interest for this study. Quantitative cycle times (CT) for mammaglobin (MG) and CK19 were correlated with finding ≥4+LN on final pathology. Results: Median tumor size was 2.0 cm (range; 0.2–5.0 cm). Median number of SLN removed was 3 (range; 1–11). 18 patients (15.7%) had ≥4 +LN on final pathology. Median CT for MG was 29.1 (interquartile range (IQR): 24.7–39.0) in patients with <4 +LN vs. 21.4 (IQR: 18.5–26.8) in those with ≥4 +LN, p<0.001. Median CT for CK19 was 23.7 (IQR: 20.9–28.2) in patients with <4 +LN vs. 19.6 (IQR: 17.8–20.7) in those with ≥4 +LN, p<0.001. Tumor size ≥2cm, proportion of SLN+ >50%, MG CT <25.8 and CK19 <20.8 were correlated with ≥4 +LN on final pathology. On multivariate analysis, tumor size, MG CT and CK19 CT were significant (see table). A simplified CPR was created with 1 point given if tumor size was ≥2cm, 1 point if MG CT <25.8 and 2 points if CK19 CT<20.8. Of the 24 patients (20.9%) with 0 points, only 1 (4.2%) had ≥4 +LN; of the 12 patients (10.4%) with 3 points, 8 (66.7%) had ≥4 +LN on final pathology, p<0.001. Area under the receiver-operator curve was 86.2% (95% CI: 76.1%-96.2%). Conclusions: Intraoperative quantitative RT-PCR of SLN improves prediction of ≥4 +LN; further validation of this model will have clinical utility regarding the use of immediate, delayed, or delayed-immediate reconstruction approaches.

Abstract
e15508 Background: Gemcitabine (G) is regarded as the standard treatment for pts with APC. However, a standard second-line chemotherapy regimen has yet to be defined after G. PHY906, a 4-herb traditional Chinese medicine has a history of > 1,800 yrs of human use to treat GI symptoms including diarrhea. Preclinical studies showed that PHY906 may potentiate antitumor activity of CAP in human PANC-1 xenograft (ASCO 2007). A phase I study showed that CAP can be escalated up to 1750 mg/m2 PO BID on d1- 7 and PHY906 800mg PO BID on d1–4 q 2 wks with no DLTs (ASCO, 2008). Delivered dose-intensity of CAP was similar at 1750mg/m2 dose level as 1500mg/m2. Therefore, 1500mg/m2 of CAP and PHY906 was further tested in a phase II study as second-line treatment in pts with APC. Methods: Pts with G-refractory APC with ECOG PS <2 were treated with CAP 1500mg/m2 d1–7 with PHY906 800mg d1–4 q 2 wks. Response was assessed by CT scan according to RECIST q 6 wks and toxicity according to NCI-CTC v3.0. Primary objective is overall survival. Secondary objectives include overall RR, PFS and measurement of cytokines to assess inhibition of NF-kappa B, a possible mechanism responsible for PHY906's pharmacological activity. Results: As of January 5, 2009, 25 pts have been enrolled. Baseline characteristics include median age, 65 (range, 40–85); male/female,15/10; ECOG PS 0/1, 4/19; median cycles: 3 (r: 0.5–15). At this point 5 pts are still in active treatment. 4 pts have confirmed OS > 6 ms (1 still on study) with 2 further pts approaching 6 ms. Among evaluable pts, 1 had PR (5.3%), 11 SD (57.9%) and 7 PD (36.8%) after initial restaging scan. 36 % pts had >30% reduction in CA19–9 as biochemical response. There were 7 deaths on/within 30 days of study treatment, 6 related to PD and 1 had acute MI. G3/4 toxicities diarrhea 3/25 (12%), fatigue, 1/25 (4%), HFS 1/25 (4%) and mucositis 1/25 (4%). 1 pt was removed from study due to G3 HFS. Biomarker studies (IL4, GM-CSF, TNF-alpha, IL10, MCP-1, IL2, IL6) are ongoing. Conclusions: This is the first clinical study to evaluate a botanical formulation PHY906 with CAP in G-refractory APC pts. CAP + PHY906 regimen appears a safe and feasible salvage therapy in APC and warrants further investigation. In addition, PHY906 may have a cytoprotective antidiarrheal and anti-HFS effect, making treatment with CAP more tolerable. [Table: see text]

Abstract #6031
Background: Approximately 50% of patients who are diagnosed with Ductal Carcinoma In-Situ (DCIS) develop invasive breast cancer. The progression from DCIS to invasive cancer is not well understood. To better understand the range of biological processes involved in this progression, we have successfully isolated primary epithelial cell cultures from patient breast tissue and are using mass spectrometry-based methods to identify differentially expressed proteins in these different cell types. Bioinformatics analysis was used to identify differences in the underlying pathways.
 Methods: Primary Human Mammary epithelial cells from DCIS and Stage 3 Invasive tumors and normal tissue from the same patient were isolated immediately after surgery. Cells were maintained in defined CNT27 media for up to 2 passages and were characterized for epithelial and breast cancer markers by immunohistochemistry and western blot. Tamoxifen response was measured by cell proliferation assay. Protein lysates were labeled with the ITRAQ isobaric tags. Two-dimensional high-pressure liquid chromatography and mass spectrometry were used to identify differentially expressed proteins.
 Results: The proliferation rate of cells from DCIS tissue was 33% higher than the matched control cells and 50% higher from invasive tissue. Furthermore, Tamoxifen was more effective at inhibiting DCIS cell proliferation than the invasive cells in a dose- and time-dependent manner. We identified 50-100 proteins differentially expressed between the different tissue types. Validated tumor markers such as members of protein S100 family were significantly different between the tumor and normal samples. Thrombospondin, a known angiogenesis inhibitor, had similar concentrations in normal and DCIS tissues but was down-regulated (ratio=0.4) in the invasive tumor samples.
 Discussion: Using the analogous methods from gene expression studies, we found that pathways associated with processes such as differentiation, angiogenesis, and invasion are enriched in the proteome of the invasive tumors. Further comparisons of additional samples is continuing with the goals of better understanding the underlying biology that drives DCIS to invasive breast cancer and ultimately defining markers that could be used in better prognosis for DCIS patients.

Abstract
SSc is a chronic progressive disorder of unknown aetiology characterized by excess synthesis and deposition of collagen and other extracellular matrix components in a variety of tissues and organs. Localized scleroderma (LS) differs from SSc in that with LS only skin and occasionally subcutaneous tissues are involved. Although rarely life threatening, LS can be disfiguring and disabling and, consequently, can adversely affect quality of life. There is no known effective treatment for LS, and various options, including, as examples, corticosteroids and other immunomodulatory agents, ultraviolet radiation and vitamin D analogues, are of unproven efficacy. Clinical trials evaluating combination therapy such as corticosteroids with MTX or UVA1 exposure with psoralens have not been established as consistently effective. New immunomodulators such as tacrolimus and thalidomide are also being evaluated. A better understanding of the molecular and cellular mechanisms of LS has led to evaluation of new treatments that modulate profibrotic cytokines such as TGF-beta and IL-4, regulate assembly and deposition of extracellular matrix components, and restore Th1/Th2 immune balance by administering IL-12 or IFN-gamma. IFN-gamma acts by directly inhibiting collagen synthesis and by restoring immune balance. In this review, we evaluate current and future treatment options for LS and cutaneous involvement in SSc. Recent advances in therapy focus mainly on anti-fibrotic agents. Delivery of these drugs into the skin as the target tissue might be a key factor in developing more effective and safer therapy.

Abstract
Cellular membranes obtained from the 1321N1 and A172 astrocytoma cell lines were immobilized on a chromatographic phase to create cellular membrane affinity chromatography (CMAC) columns, CMAC(1321N1) and CMAC(A172). The columns were characterized using frontal affinity chromatography with [(3)H]-epibatidine as the marker ligand and epibatidine, nicotine, and methyllycaconitine as the displacers. The results indicated that the columns contained homomeric alpha7 nicotinic acetylcholine receptors (alpha7 nAChR) and heteromeric nicotinic acetylcholine receptors (alpha(x)beta(y) nAChRs), which was confirmed by the addition of subtype-specific inhibitors, alpha-bungarotoxin (alpha7 nAChR) and kappa-bungarotoxin (alpha(x)beta(y) nAChR) to the mobile phase. The presence of two additional ligand-gated ion channels (LGICs), gamma-aminobutyric acid (GABA(A)) and N-methyl-D-aspartic acid (NMDA), was established using frontal affinity chromatography with flunitrazepam and diazepam (GABA(A) receptor) and MK-801 and NMDA (NMDA receptor). The presence of the four LGICs was confirmed using confocal microscopy and flow cytometry. The results indicate that the CMAC(1321N1) and CMAC(A172) columns contain four independently functioning LGICs, that the columns can be used to characterize binding affinities of small molecules to each of the receptors, and that the CMAC approach can be used to probe the expression of endogenous membrane receptors.

Abstract
The design, fabrication, and properties of one of a new class of gradient-index lenses are reported. The lens is an f/2.25 GRIN singlet based on a nanolayered polymer composite material, designed to correct for spherical aberration. The light gathering and focusing properties of the polymer lens are compared to a homogeneous BK7 glass singlet with a similar f-number. The modulation transfer function of the polymer GRIN lens exceeded that of the homogeneous glass lens at all spatial frequencies and was as much as 3 times better at 5 cyc/mm. The weight of the polymer lens was approximately an order of magnitude less than the homogeneous glass lens.

Abstract
A simple, modified method to evaluate changes in the nasolabial soft tissues after orthognathic surgery is presented. Eighteen healthy volunteers were photographed in a standardized manner with a 2-month interval. Pictures were taken with the soft tissues in repose and 'maximum closed mouth smile'. Discrepancies for repose and dynamic excursions (x and y coordinates) were calculated for the landmarks alare, crista philtri and cheilion. Multiple analysis of variance revealed no significant interaction for intra-observer variance and time of recording. Coefficients of reliability (repose: 90-99%, dynamic excursion (cheilion): >95%), Spearman correlation coefficients (repose: >0.8, dynamic: >0.6) and squared correlation (repose: >75%, dynamic: >50%) showed this method to be reliable for repose and dynamic excursions. The error of measurement was less than 1.8 mm for both repose and dynamic excursions (SD(differences)=0.9 mm). This is smaller than mean differences in nasolabial soft-tissues excursions found between the pre- and post-Le Fort I osteotomy situation in a previous study using video imaging. The discrepancies found were in keeping with other earlier reports for 2D and 3D measuring methods. The method as proposed is simple, cost effective and can be used to evaluate soft-tissue changes after orthognathic surgery.

Abstract
1543 Background: Breast cancer survival is improved by early diagnosis. The role of self-exam as an adjunct to screening mammography has been questioned as some studies suggest that self-examinations lead to unnecessary diagnostic procedures without improving survival. Methods: Patients who had been diagnosed with breast cancer and who were attending a university-based cancer clinic were interviewed, using a structured questionnaire, to determine the way in which their breast cancers were first identified. Inference was conducted using exact methods (Clopper-Pearson intervals for proportions and Fisher’s test for odds ratios). Results: Breast cancers were first identified by mammogram in 16% of women, by provider in 9%, by the spouse in 2%. Seventy-five percent (95% CI=61% to 85%) of patients first identified their tumors by self exam. Self-identifiers occurred in all demographic groups. These women included those with all types of insurance: private insurance (68%), Medicare (60%), Medicaid (100%), or no insurance (85%); all levels of education: 77% with college education and 75% with high school; all income levels: for example, among 79% with annual incomes of <$10K and 73% with incomes >$50K; and among both black (91%) and white (66%) women. Of the women who reported both regular mammograms and regular self-examination (N=35), 77% (95% CI=60 to 90%) were self-identifiers. However, cancers found by mammography were more likely to be Stage I than were those identified by self-examination (odds ratio=3.9, 95% CI .9 to 17.5, p=.047). Conclusions: Most breast cancers (75%) were found by self-examination, even among women who had regular mammography. We did not find any demographic factor that predicted mammography as the primary method of tumor identification. These findings suggest that self-examination remains an important method of breast cancer identification. No significant financial relationships to disclose.

Abstract
Since the introduction of osteosynthesis materials for rigid internal fixation after anatomical reduction there is an ongoing discussion about the treatment of condylar fractures of the mandible. Sixty patient files were analyzed and 28 patients were seen for re-examination and a x-orthopantomogram was taken. Functionality was graded with the Helkimo index at an average of 3.0 years follow-up. The clinical dysfunction index showed: severe symptoms in 11%, moderate symptoms in 39%, mild symptoms in 39% and 11% had no symptoms. Index for occlusal state showed: 21% severe occusal disturbances, 61% moderate occlusal disturbances and 18% no occlusal disturbances. According to the anamnestic dysfunction index 89% of the patients were symptom-free. The clinical outcome group showed a significant left/right ramus length difference compared with a 20-person control group. The re-examined group did not significantly differ from the control group. Conservative treatment for condylar fractures was successful in only 46% according to the 1999 consensus criteria described by Bos et al.
