Abstract
Abstract
PurposeThe tumor suppressor gene RASSF1 (Ras association domain family member 1) regulates cell cycle, progression, apoptosis, and microtubule stability, and is inactivated by promoter hypermethylation in breast cancer. We analyzed the SNPs in RASSF1 and their predictive and prognostic value in stage II or III breast cancer patients who received neoadjuvant docetaxel/doxorubicin chemotherapyMethodsA total of 139 stage II or III breast cancer patients who received neoadjuvant docetaxel/doxorubicin chemotherapy were enrolled in this study. The patients received three cycles of neoadjuvant chemotherapy followed by curative surgery, and received additional three cycles of docetaxel/doxorubicin chemotherapy as an adjuvant. Germline DNA from peripheral blood mononuclear cells was extracted. The genotypes were performed using Illumina GoldenGate® Assay. We analyzed 3 SNPs in RASSF1 genes: rs3213621 T>C in 3'UTR, rs2073499 G>A in intron, and rs2073498 C>A in exon 3 Ala133Ser.ResultsThe overall radiologic response rate (RR) for neoadjuvant chemotherapy was 79.8% and 10 patients (7.2%) achieved a pathologic complete remission (pCR). None of the SNPs were correlated with radiologic RR or pCR rate. SNP in intron of RASSF1 (rs2073499) was associated with relapse free survival (RFS). RFS was longer in GA/AA genotype than GG genotype (Hazard ratio [HR]=0.374, p=0.034) After adjusting age and hormone status, prognostic value of RASSF1 SNP remained significant (HR=0.393, p=0.050). Other two SNPs were not significantly associated with RFS.ConclusionsThe GA/AA genotype in SNP of RASSF1 (rs2073499) is associated with significantly longer RFS than the GG genotype. Further research is warranted to identify the biologic characteristics of RASSF1.

Abstract
Abstract #1085
Backgroud Metaplastic breast carcinomas (MBC) are a rare type of breast cancer comprising <1% of all invasive breast cancers and are generally characterized by hormone receptor and human epidermal growth factor receptor 2 (HER2) negativity. There is a paucity of information on prognosis according to hormone receptor and HER2 expression for these rare tumors. The aim of this study was to compare the clinical features and prognosis, between triple negative metaplastic carcinoma (TNMC) and non-triple negative metaplastic carcinoma (NTNMC).
 Material and Methods We retrospectively analyzed MBC patients treated at Seoul National University Hospital between 1996 and 2006. Pathologic, immunohistochemical findings and clinical outcome information were reviewed.
 Results fifty-one patients were identified. The median age at presentation was 45.8 years (range: 27.3-83.8). Median tumor size at diagnosis was 3.0 cm (range: 0.8-12.0). 34 cases (66.7%) were node-negative, 16 (31.4%) node-positive, and 1 (2.0%) were missing. Estrogen receptor (ER)/progesterone receptor (PR) yielded negative results in 49 cases (96.1%) and 48 cases (94.1%), respectively. HER2 overexpression by immunohistochemistry was negative in 41 of 51 (80.4%). At median follow-up of 40.8 months, the 5-year overall survival rate and disease free survival were 73.9% and 64.9%, respectively. Non-triple negativity (p=0.031) correlated significant with overall survival in multivariate analysis.
 Of the 51 patients, 39 (76.5%) were TNMC, and 12 (23.5%) were NTNMC. In TNMC and NTNMC group, median ages were 45.6 and 51.5 years and tumor sizes were 3.0 cm and 3.0 cm, respectively. There were 12 patients (30.8%) in TNMC and 4 patients (33.3%) in NTNMC for lymph node metastasis. Two groups did not differ significantly by age, tumor size, or nodal status. Positive rates for ER, PR and HER2 were 16.7%, 25% and 83.3% in NTNMC. The 3-year overall survival rates in TNMC and NTNMC were 91.4% and 61.9%, respectively (p=0.029). As regards to 3-years disease-free survival, there was no statistically significant difference between TNMC and NTNMC (p=0.694, 75.8% versus 75.0%).
 Discussion MBC mainly has triple negative features. However, in subgroup analysis of MBC, non-triple negative group displayed a poor prognosis compared with triple negative group, which is contrary to the case of invasive ductal carcinoma of breast. Further research exploring mechanism of this result.

Abstract
The effect of total radiation dose (TRD) on the outcome of patients with postoperative radiotherapy (RT) for squamous cell carcinoma of esophagus was assessed. Sixty-seven patients with esophagectomy, followed by postoperative RT for squamous cell carcinoma of esophagus from June 1984 through February 2001, were retrospectively reviewed. Of these, 13 patients were excluded. No patient had chemotherapy. Patients were classified into two groups based on TRD delivered: TRD of less than 50 Gy (Group A, n = 16) and at least 50 Gy (Group B, n = 38). Follow-up duration of all patients ranged from 4 to 140 months (median, 14). Median TRD of Group A and B were 45 Gy (range, 45-48.6) and 54 Gy (range, 50-59.6), respectively. Median overall survival (OS) and disease-free survival (DFS) of all patients were 15 and 10 months, respectively. Although the TRD of 50 Gy or higher was marginally significant for improved OS (hazard ration [HR] 0.559, P = 0.066), it was statistically significant for improved DFS (HR 0.398, P = 0.011), and locoregional recurrence-free survival (HR 0.165, P = 0.001) with multivariate analysis. Three patients in group A and two in group B experienced a complication of grade 3 or higher. Our study suggests a positive impact of TRD of 50 Gy or higher on DFS and locoregional control, with acceptable morbidity in postoperative RT for patients with squamous cell carcinoma of esophagus. According to the present analysis, TRD should be at least 50 Gy in postoperative RT alone setting.

Abstract
15122 Background: Despite the use of 5-FU based chemoradiotherapy (CRT) over the past decades, prognosis of patients with LAPC remains dismal. To deliver more efficient systemic treatment earlier and reduce toxicity of CRT, we designed a treatment protocol consisting of induction (IND) chemotherapy with FDR gemcitabine (GEM) and cisplatin (CDDP), followed by CRT with capecitabine (CAP) in LAPC. Methods: Eligible patients had unresectable, histologically confirmed adenocarcinoma of pancreas, ECOG PS of 0–2, and no prior chemo- or radiotherapy for this phase II study. Patients received FDR GEM 1000 mg/m2 (D1,8) and CDDP 60 mg/m2 (D1) every 3 weeks for 3 cycles. Patients without disease progression subsequently received CRT of 55.8 Gy in 31 fractions concurrently with CAP, 650 mg/m2 given twice daily without drug holidays. Four weeks after CRT, FDR GEM 1000 mg/m2 was given on day 1, 8 every 3 weeks for 3 cycles. Time to progression was the primary endpoint. Results: Between Jan 2005 and Nov 2006, 21 patients were enrolled (median age 59, M/F: 13/8, ECOG PS 0/1: 3/18). Two patients withdrew consent after 1st and 2nd cycle and remaining 19 patients completed all three cycles of IND chemotherapy, with three (15.8%) out of 19 evaluable patients achieving partial response (0 CR, 3 PR, 14 SD, 2 PD). All 17 patients completed CRT with mean radiation dose of 55.4 Gy. Further four patients progressed during CRT, while one additional patient achieved partial response. As of Jan 2007, 5 patients died and 12 patients showed tumor progression. Median TTP was 12.5 mo (95% CI: 4.2–20.8) and median survival was not reached with median follow up duration of 9.7 months. Grade III/IV toxicities included neutropenia (38.1%/9.5%), thrombocytopenia (4.8%/0%), and anemia (14.3%/0%) during IND phase. Toxicites were generally mild during CRT phase with grade III neutropenia and diarrhea occurring in one and two patients, respectively. One patient died of neutropenic sepsis after 3rd cycle of IND chemotherapy. Conclusions: FDR GEM-CDDP induction chemotherapy followed by CAP-RT and maintenance FDR GEM is feasible and active with promising TTP of 12.5 months. Enrollment continues till reaching target accrual of 37 patients. No significant financial relationships to disclose.

Abstract
Injury to a peripheral nerve induces in the dorsal root ganglia (DRG) sprouting of sympathetic and peptidergic terminals around large-diameter sensory neurons that project in the damaged nerve. This pathological change may be implicated in the chronic pain syndromes seen in some patients with peripheral nerve injury. The mechanisms underlying the sprouting are not known. Using in situ hybridization and immunohistochemical techniques, we have now found that nerve growth factor (NGF) and neurotrophin-3 (NT3) synthesis is upregulated in satellite cells surrounding neurons in lesioned DRG as early as 48 h after nerve injury. This response lasts for at least 2 months. Quantitative analysis showed that the levels of mRNAs for NT3 and NGF increased in ipsilateral but not contralateral DRG after nerve injury. Noradrenergic sprouting around the axotomized neurons was associated with p75-immunoreactive satellite cells. Further, antibodies specific to NGF or NT3, delivered by an osmotic mini-pump to the DRG via the lesioned L5 spinal nerve, significantly reduced noradrenergic sprouting. These results implicate satellite cell-derived neurotrophins in the induction of sympathetic sprouting following peripheral nerve injury.

Abstract
1. Two neuronal growth factors, nerve growth factor (NGF) and neurotrophin 3 (NT3), have been studied for their action on the developing and mature sympathetic nervous system. 2. Antibodies to each factor have proved useful as reagents for the detection and quantification of NGF and NT3. They have also proved valuable in uncovering the functional roles of each factor by their ability to neutralize the endogenous molecules. 3. Nerve growth factor acts on postnatal neurons to control neurotransmission, connectivity and survival. Like NGF, NT3 is synthesized by effector tissues and is retrogradely transported by post-ganglionic neurons to prevent cell death. However, the two factors have been shown to have quite distinct functions in mature neurons, indicating the existence of different signalling pathways. This differential action extends to secondary influences on satellite glia. 4. Pathological consequences result from excessive growth factor synthesis leading, in the hypertensive rat, to hyperinnervation and elevated blood pressure. Satellite glial cell synthesis of the factors and their receptors following peripheral nerve damage appears to be responsible for the establishment of inappropriate neuronal connections between sympathetic nerve terminals and sensory somata. 5. It is concluded that these potent factors control, by both coincident and independent mechanisms, sympathetic neuronal function throughout the life of the animal.
