Abstract
Abstract
Background
The continuum of anti-HER2 agents is regarded as a standard strategy for HER2 positive metastatic breast cancer patients who had progressed disease with anti-HER2 agent- containing treatments. However, there has been lack of data on which agents should be continued and how long continuous anti-HER2 therapies would be effective. This study was aimed to evaluate the efficacy of lapatinib plus vinorelbine in HER2 positive metastatic breast cancer patients who had progressed on both trastuzumab and lapatinib treatments.
Methods
A total of 149 patients were randomly assigned to lapatinib with vinorelbine (LV) (n=75; laptinib, 1000mg daily ; vinorelbine 20mg/m2 D1,D8 q3w) or vinorelbine alone (V) (n=74; 30mg/m2 D1,D8 q3w). The stratification factors were followings; 1) visceral metastasis, 2) previous response to lapatinib treatment, CR+PR vs. SD ≥ 12 weeks. The primary endpoint was progression free survival (PFS) rate at 18 weeks. The secondary endpoints were objective response rate (ORR), PFS, and overall survival (OS).
Results :
Both arms were well balanced in various clinical factors. The median number of previous anti-HER2 therapies were 2 (range 2-5). There was no significant difference in PFS rate at 18 weeks between LV and V arms (44.0% vs 36.5%, p=0.44). ORR was 19.7% in LV arm and 16.9% in V arm (p=0.881). PFS and OS did not differ between two arms (LV vs V; median PFS, 16weeks vs 12 weeks, HR= 0.86, 95% CI 0.61-1.22, p=0.41; median OS, 15.0 months vs 18.9 months, HR= 1.07, 95% CI 0.72-1.58, p=0.72). In subgroup analysis, there was no difference in PFS and OS between two arms according to previous response to lapatinib (median PFS, CR+PR vs. SD ≥ 12 weeks, 12.1weeks vs.17.4 weeks; HR= 1.242, 95% CI 0.881-1.751, p=0.215; median OS, 14.9 months vs. 19.4 months; HR= 1.179, 95% CI 0.797-1.744, p=0.41). Most common adverse events in both arms were neutropenia which was more often observed in V arm (55% vs 73%, p=0.03). Overall, the profiles of adverse events were similar in both arms and all were manageable.
Conclusion
Lapatinib plus vinorelbine treatment was tolerable, however, it did not demonstrate the clinical benefits compared to vinorelbine alone in HER2 positive metastatic breast cancer patients after progression on both trastuzumab and lapatinib.

Abstract
The 15th St. Gallen International Breast Cancer Conference 2017 in Vienna, Austria reviewed substantial new evidence on loco-regional and systemic therapies for early breast cancer. Treatments were assessed in light of their intensity, duration and side-effects, seeking where appropriate to escalate or de-escalate therapies based on likely benefits as predicted by tumor stage and tumor biology. The Panel favored several interventions that may reduce surgical morbidity, including acceptance of 2 mm margins for DCIS, the resection of residual cancer (but not baseline extent of cancer) in women undergoing neoadjuvant therapy, acceptance of sentinel node biopsy following neoadjuvant treatment of many patients, and the preference for neoadjuvant therapy in HER2 positive and triple-negative, stage II and III breast cancer. The Panel favored escalating radiation therapy with regional nodal irradiation in high-risk patients, while encouraging omission of boost in low-risk patients. The Panel endorsed gene expression signatures that permit avoidance of chemotherapy in many patients with ER positive breast cancer. For women with higher risk tumors, the Panel escalated recommendations for adjuvant endocrine treatment to include ovarian suppression in premenopausal women, and extended therapy for postmenopausal women. However, low-risk patients can avoid these treatments. Finally, the Panel recommended bisphosphonate use in postmenopausal women to prevent breast cancer recurrence. The Panel recognized that recommendations are not intended for all patients, but rather to address the clinical needs of the majority of common presentations. Individualization of adjuvant therapy means adjusting to the tumor characteristics, patient comorbidities and preferences, and managing constraints of treatment cost and access that may affect care in both the developed and developing world.

Abstract
In treating HR+, HER2− metastatic breast cancer, novel agents that enhance endocrine therapy activity but do not worsen quality of life (QoL) are clinically desired. Patient-reported outcomes data from the PALOMA-3 study suggest palbociclib plus fulvestrant allow patients to maintain good QoL in the endocrine resistance setting while experiencing a substantially delayed disease progression. Background In the PALOMA-3 study, palbociclib plus fulvestrant demonstrated improved progression-free survival compared with fulvestrant plus placebo in hormone receptor-positive, HER2− endocrine-resistant metastatic breast cancer (MBC). This analysis compared patient-reported outcomes (PROs) between the two treatment groups. Patients and methods Patients were randomized 2 : 1 to receive palbociclib 125 mg/day orally for 3 weeks followed by 1 week off (n = 347) plus fulvestrant (500 mg i.m. per standard of care) or placebo plus fulvestrant (n = 174). PROs were assessed on day 1 of cycles 1–4 and of every other subsequent cycle starting with cycle 6 using the EORTC QLQ-C30 and its breast cancer module, QLQ-BR23. High scores (range 0–100) could indicate better functioning/quality of life (QoL) or worse symptom severity. Repeated-measures mixed-effect analyses were carried out to compare on-treatment overall scores and changes from baseline between treatment groups while controlling for baseline. Between-group comparisons of time to deterioration in global QoL and pain were made using an unstratified log-rank test and Cox proportional hazards model. Results Questionnaire completion rates were high at baseline and during treatment (from baseline to cycle 14, ≥95.8% in each group completed ≥1 question on the EORTC QLQ-C30). On treatment, estimated overall global QoL scores significantly favored the palbociclib plus fulvestrant group [66.1, 95% confidence interval (CI) 64.5–67.7 versus 63.0, 95% CI 60.6–65.3; P = 0.0313]. Significantly greater improvement from baseline in pain was also observed in this group (−3.3, 95% CI −5.1 to −1.5 versus 2.0, 95% CI −0.6 to 4.6; P = 0.0011). No significant differences were observed for other QLQ-BR23 functioning domains, breast or arm symptoms. Treatment with palbociclib plus fulvestrant significantly delayed deterioration in global QoL (P < 0.025) and pain (P < 0.001) compared with fulvestrant alone. Conclusion Palbociclib plus fulvestrant allowed patients to maintain good QoL in the endocrine resistance setting while experiencing substantially delayed disease progression. Clinical Trial Registration NCT01942135.

Abstract
Abstract
Background: Endocrine therapy (ET) resistance remains a major clinical problem for patients (pts) with hormone receptor (HR+) breast cancer (BC). In PALOMA-3, palbociclib (P) combined with fulvestrant (F) demonstrated significant prolongation of progression-free survival (PFS) vs F plus placebo (PLB) in pre/peri and postmenopausal women with HR+/HER2– metastatic BC (MBC) whose disease progressed on prior ET (median PFS 9.2 vs 3.8 m; HR=0.422, P=0.0001).
Methods: In this double-blind phase 3 study, 521 pts with HR+/HER2– MBC were randomized 2:1 to receive P (125 mg/d orally for 3 weeks followed by 1 week off) and F (500 mg given per standard of care) or PLB plus F. Pre- and perimenopausal women also received goserelin. One previous line of chemotherapy (CT) for MBC was allowed. Safety assessments occurred at baseline and D1 of each cycle; blood counts occurred every 2 wks for the first 2 cycles and on D1 of subsequent cycles. As pts may have experienced multiple episodes of neutropenia during treatment, we analyzed all episodes in aggregate based on laboratory data per CTCAE4.0.
Results: The results reported here are from the data cutoff of Dec 2014, with a median follow-up of 5.6 m. Overall rate of any grade (G) and G3/4 AEs was 98/70% of pts in P+F vs 89/18% in PLB+F. The most commonly reported AEs in P+F (≥20%) were hematologic toxicities, fatigue, nausea, and headache. Per lab data, G3/G4 neutropenia occurred in 52.2/8.2%, G3/G4 leukopenia in 39.5/1.2%, G3/G4 anemia in 20.8/2.9% and G3/G4 thrombocytopenia in 2.1/1.2% of pts on P+F. Neutropenia occurred early, with a median onset time for first episode of ≥G3 neutropenia of 15 d (13–197) and median time from first dose to the lowest absolute neutrophil count (ANC) of 29 d (13–334). The median duration of ≥G3 episode was 7 d (1–35), suggesting that most pts can resume treatment after a 1-week cycle delay. A comparable proportion of any grade neutropenia was observed in pts with or without prior CT (prior CT 88.4% vs no prior CT 85.4%). There was no difference in the rate of G3/G4 neutropenia in the older pts (>65 yrs, 51% vs ≤65 yrs, 57%) in P+F arm. Concurrent G≥3 infections occurred in 1% of pts with G≥3 neutropenia (2/192 pts). Febrile neutropenia occurred in 0.6% of pts in both arms. 21% of pts had dose reductions and 45% had dose interruption due to neutropenia. Dose intensity was maintained at 89.7% for P. Serious adverse events (SAEs) were reported in 9.6% of pts on P+F and in 14% of pts on PLB+F. The most common SAEs on P+F were pulmonary embolism (0.9%) and pyrexia (0.9%). Safety analyses with longer follow-up (data cut off, March 2015) are ongoing and will be presented.
Conclusions: Findings suggest P+F has a favorable safety profile characterized mainly by asymptomatic hematologic toxicity. Overall SAE rates were low and comparable between the 2 arms. Palbociclib-related neutropenia differs from that seen with CT, consistent with proposed mechanism of action, in that it is not commonly associated with fever, and can be effectively managed by a dose interruption or cycle delay.

Abstract
Abstract
Background: Growing evidence suggests that concomitant inhibition of the phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin pathway could enhance and extend the clinical benefit of endocrine therapies in hormone receptor-positive (HR+) metastatic breast cancer (mBC). In this Phase Ib study (NCT02058381), alpelisib (a p110α-selective inhibitor) or buparlisib (a pan-PI3K inhibitor) was combined with tamoxifen and goserelin acetate in premenopausal women with mBC, a more prevalent patient population in Asian vs Western countries.
Methods: Premenopausal women with HR+/human epidermal growth factor receptor 2-negative (HER2–) locally advanced or mBC and no prior endocrine therapy for metastatic disease were recruited in Taiwan, Republic of Korea, and Thailand. Patients (pts) received tamoxifen (20 mg once daily [QD]) and goserelin (3.6 mg Q28D) with either alpelisib (350 mg QD; Group 1) or buparlisib (100 mg QD; Group 2) on a continuous dosing schedule in 28-day cycles. The primary objective was to define the recommended Phase II dose (RP2D) for each combination, based on dose-limiting toxicities (DLTs) observed during Cycle 1, using a dose de-escalation design. Secondary objectives included pharmacokinetics, safety and tolerability (per Common Terminology Criteria for Adverse Events v4.03), efficacy (per Response Evaluation Criteria In Solid Tumors v1.1), and impact on quality of life.
Results: As of February 2, 2015, 12 pts, all Asian, have been treated in the first cohort. In Group 1, 6 pts with a median age of 43 were treated with alpelisib (350 mg starting dose), and no DLTs were observed in Cycle 1. In Group 2, 6 pts with a median age of 47 were treated with buparlisib (100 mg starting dose), and 1 DLT of Grade (G) 3 alanine aminotransferase/aspartate aminotransferase elevation was observed. In Group 1, significant toxicities included hypokalemia (G3: 1 pt), rash (G3: 1 pt; G1/2: 2 pts), anemia (G3: 1 pt), leukopenia (G3: 1 pt), and infections (G3: 1 pt; G1/2: 1 pt); no G4 toxicities were reported. In Group 2, significant toxicities included liver toxicity (G4: 1 pt; G3: 1 pt; G1/2: 2 pts), psychiatric disorders (G4: 1 pt; G3: 1 pt; G1/2: 1 pt), rash (G3: 1 pt; G1/2: 2 pts), hypertension (G3: 1 pt; G1/2: 1 pt), and hyperglycemia (G3: 1 pt). No pts in Group 1, and 5/6 pts in Group 2, have discontinued treatment due to adverse events (AEs). Median treatment duration was 110 days in Group 1 and 71 days in Group 2.
Conclusions: The combination of alpelisib (350 mg) with tamoxifen and goserelin resulted in a manageable toxicity profile. Meanwhile, the same combination with full-dose buparlisib (100 mg) was less well tolerated; despite the appearance of only one DLT during Cycle 1, the majority of pts subsequently stopped treatment due to AEs. An expansion phase is ongoing, and results will be integrated with safety, tolerability, and efficacy results for the first 15 pts enrolled in each group. PIK3CA status at baseline will also be assessed.

Abstract
Abstract
Background: Ki-67 has been increasingly used as a prognostic marker in spite of debates on the evaluation methods and inconsistent results on its clinical values. CKAP2 is a microtubule-associated protein which plays key roles in microtubule assembly and disassembly. In the present study, the clinical significance of CKAP2-positive cells was evaluated and compared with the results of Ki-67 positive cells.
Methods: A total of 579 early breast cancer patients who underwent surgery at the National Cancer Center Hospital between 2001 and 2005 were accrued. The proliferation activity was measured by CKAP2-positive cell count (CPCC) and Ki-67 labeling index (Ki-67 LI) using CKAP2 and Ki-67 antibodies, respectively, by immunohistochemcial staining on FFPE tumor tissue. The correlation of CPCC or Ki-67 LI with recurrence free survival (RFS) was analyzed. The immunofluorescent staining was performed on HeLa cells after synchronization by double thymidine block to compare the patterns between CKAP2 and Ki-67.
Results: The CPCC (median, 8 with the range of 0- 170) and Ki-67 LI (median, 10.2 with the range of 0%- 91.7%) were highly correlated (R = 0.754, P < 0.001). While CPCC was marginally significant in multivariate analysis for RFS in all cases, it was a significant variable for RFS in the subset analysis with HER2-negative luminal breast cancer patients (HR, 3.154; 95% CI, 1.154-10.693; P = 0.027). On the contrary, Ki-67 LI failed to show any correlation with RFS in all or any subgroups. In the analysis on HeLa cells, CKAP2 staining was more specific to cells in metaphase than Ki-67 staining.
Conclusions: CPCC can be an independent prognostic factor specifically in a HER2-negative luminal type of breast cancer. In addition, CPCC appears to be superior to Ki-67 LI as a survival indicator which may be related to the restricted expression pattern of CKAP2 in metaphase cells. Further study is warranted.

Abstract
Abstract
Background: Selective estrogen receptor modulators and aromatase inhibitors (AI) (+LHRH agonists [premenopausal]) are standard of care (SOC) for hormone–receptor–positive (HR+) metastatic breast cancer (MBC). Many HR+ MBC patients (pts) get limited benefit from adjuvant or advanced endocrine therapy (ET) and develop endocrine resistance, refractory disease. HR+ BC growth relies on cyclin dependent kinases 4/6 that promote G1–S phase cell cycle progression. Palbociclib (PAL) with ET showed efficacy in HR+/HER2– MBC (Turner et al, 2015). We report updated safety and efficacy from PALOMA3 with longer follow–up, focusing on degrees of clinically defined endocrine resistance.
Methods: Pts with HR+/HER2– MBC that progressed on prior ET were randomized 2:1 to PAL (125 mg/d oral [3 wks drug, 1 wk off]) + fulvestrant (F, 500 mg, SOC) +/– goserelin or placebo (PLB)+F. One line of chemotherapy (CT) for MBC was allowed. Pt stratification: prior ET sensitivity; visceral metastases; menopausal status. Primary endpoint (EP) was investigator–assessed progression–free survival (PFS). Secondary EP: overall survival, response assessment, patient–reported outcomes, safety.
Results: By March 2015, median follow–up was 8.9 mo. 521 pts were randomized (PAL+F, 347; PLB+F, 174). Baseline characteristics were balanced. Median PFS was 9.5 (95% CI 9.2–11.0) mo (PAL+F) vs 4.6 (3.5–5.6) mo (PLB+F) (HR 0.46 [0.36–0.59], P<0.001). Overall response (CR+ PR) was significantly improved with PAL+F (ITT: 19% vs 8.6%, P=0.001; pts with measurable disease: 24.6% vs 10.9%, P<0.001). Clinical benefit (CBR=CR+PR+SD ?24wks) was 66.6% vs 39.7% (P<0.001). Benefit from PAL was confirmed in pre– and postmenopausal pts with PFS in premenopausal 9.5 vs 5.6 mo (HR=0.50 [0.29–0.87], P=0.006) and in postmenopausal 9.9 vs 3.9 mo (HR=0.45 [0.34–0.59], P<0.001). Common adverse events (AEs) for PAL+F vs PLB+F were neutropenia (80.9 vs 3.5%), leukopenia (49.6 vs 4.1%), and fatigue (39.1 vs 28.5%); febrile neutropenia occurred in 0.9% (P+ F) vs 0.6% pts (PLB+F). Discontinuation due to AEs was 4.0% on P vs 1.7% on PLB. The benefit of PAL+F vs PLB+F was compared in pts with various degrees of endocrine resistance: a) progression ≤12 mo of adjuvant ET completion, PFS 9.5 vs 5.4 mo (HR 0.55 [0.32–0.92], P=0.01); b) failed 1 line of ET, 10.2 vs 5.4 mo (HR 0.42 [0.29–0.59], P<0.001); c) failed 2 lines of ET, 9.9 vs 1.8 mo (HR=0.20 [0.10– 0.39, P<0.001); d) proven endocrine sensitive, 10.2 vs 4.2 mo (HR 0.42 [0.32–0.56], P<0.001); e) proven no prior endocrine sensitivity, 7.5 vs 5.4 mo (HR 0.64 [0.39–1.07], P=0.04) f) AI most recent therapy, 9.5 vs 3.7 mo (HR 0.42 [0.31–0.56], P<0.001).
Conclusion: Mature efficacy confirmed superior PFS and demonstrated significantly improved clinical response and CBR by the combination of ET and Palbociclib. It also consistently showed therapeutic benefit irrespective of menopausal status and various degrees of endocrine sensitivity. Safety profile is favorable. PAL+F may be an effective option for HR+ MBC pts.

Abstract
Abstract
BACKGROUND
Ovarian suppression with tamoxifen after chemotherapy is a promising therapeutic approach, particularly in young, high-risk breast cancer patients. Assessment of restoration of ovarian function is important with respect to the initiation of ovarian suppression.
METHODS
In total, 1289 women who remained or resumed premenopausal status after chemotherapy were randomized to receive 5 years of tamoxifen or 5 years of tamoxifen plus 2 years of ovarian suppression. Prospectively collected hormone data were available for 24 months after completing chemotherapy for 267 breast cancer patients without ovarian suppression.
RESULTS
At 6 months, a premenopausal status was identified in 56.6%, 36%, and 16.2% of patients using serum FSH, E2, and with menstruation bleeding, respectively, and about 30% more women achieved ovarian restoration using all three parameters during the 24-month follow-up. Ovarian function restoration differed significantly according to age group (log-rank, P<0.001 for all definitions). At 6 months, the distribution of patients according to hormone levels was as follows: group 1 (FSH <30 mIU/ml, E2 >20 pg/ml), 28.0%; group 2 (FSH <30 mIU/ml, E2 ≤20 pg/ml), 28.4%; group 3 (FSH ≥30 mIU/ml, E2 >20 pg/ml), 8.0%; and group 4 (FSH ≥30 mIU/ml, E2 ≤20 pg/ml), 35.6%. During the 24-month follow-up, the prevalence of menstruation restoration was higher in group 1 (71.6%) than in the other three groups. Restoration of serum E2 and menstrual bleeding occurred in 44% and 33% of patients in group 2, respectively; the corresponding percentages in group 4 were 40.6% and 28.7% (P<0.001).
CONCLUSIONS
Ovarian function should be monitored using serum FSH, serum E2, and menstruation history for at least 24 months after completing chemotherapy during tamoxifen treatment to establish eligibility for ovarian suppression.

Abstract
This study was performed to investigate the impact of pharmaceutical excipients commonly used for lymphatic transport on in vitro drug association with chylomicrons (CM). A CM association study was conducted using saquinavir solubilized in four different pharmaceutical excipients. We observed a linear relationship between saquinavir solubility and drug association, suggesting that the solubility of saquinavir in excipients is a key determinant for successful lymphatic delivery. Broadly, these results suggest that excipients with good solubilization properties may be advantageous for enhancing lymphatic drug delivery.

Abstract
Abstract
Background: The clinical benefit of combination of mTOR inhibition and anti-hormonal therapy has been previously established and represents a new standard of care for patients with hormone receptor positive (HR+) advanced breast cancer (ABC). Preclinical evaluation of the mTOR pathway demonstrates that dual inhibition of IGFR and mTOR may be additive or synergistic and abrogates the feedback activation of AKT due to rapamycin analog mTOR inhibitors. A completed phase 1 study of the combination of the mTOR inhibitor, RIDA and the anti-IGFR antibody, DALO demonstrated preliminary signals of anti-tumor activity. This was further evaluated in a recently completed phase 2 study of RIDA-DALO compared to exemestane in ER+ ABC. Final safety and efficacy results from that phase 2 study will be reported at this meeting (see Baselga et al). Building upon the clinical synergies of mTOR and EX as well as the biologic relationship of the mTOR and IGFR pathways, a clinical study has been initiated to evaluate the triplet combination of RIDA-DALO-EX compared to RIDA-EX. Methods: This is a multicenter, international, randomized phase 2 study of the triplet combination of RIDA (10 mg by mouth daily for 5 out of every 7 days), DALO (10 mg/kg IV weekly), and EX (25 mg QD) compared to RIDA (30 mg by mouth daily for 5 out of every 7 days) and EX (25 mg QD) in high KI67 (≥15%) expressing ER+, ABC. Approximately 84 patients will be randomized 1:1 to either triplet or doublet therapy. Key eligibility criteria include: HR+ and HER-2 negative measurable ABC, prior therapy with a non-steroidal aromatase inhibitor, and KI67 labeling index ≥15%. The primary endpoint of the study is progression free survival (PFS). Key secondary endpoints include evaluation of percent (%) reduction from baseline in the sum of imaging measurements (target lesion diameters or volumes) at 16 weeks between the two arms, and overall response rates. The sample size is event driven with a target of 38 PFS events, which provides approximately 80% power, at 1-sided alpha of 0.1, to detect a HR of 0.5, corresponding to an approximate 100% improvement in median PFS, from 10.6 to 21.2 months. Safety parameters or adverse experiences of special interest include hyperglycemia, stomatitis, mucosal inflammation, pneumonitis and hearing loss. Accrual has been completed with results expected in May 2014.

Abstract
Abstract
Background: Most patients with metastatic breast cancer (MBC) experience disease progression after being treated with an anthracycline or taxane. Irinotecan, a semisynthetic agent derived from the natural alkaloid camptothecin is metabolized to the active metabolite SN-38 which targets topoisomerase I leading to single and double strand DNA breaks. Irinotecan as a single agent demonstrated tumor activity with an objective response rate ranging from 5 to 23% in patients with MBC refractory to taxane and anthracycline. Irinotecan increased the activity of 5-FU, the active metabolite of capecitabine, and overcomes the negative effect of thymidylate synthase overexpression, which is the main target of an active metabolite of 5-FU. A phase II study that evaluated the efficacy and safety of irinotecan and capecitabin combination (IX) showed that the median progression free survival (PFS) was 7.6 months (95% CI, 5.0-10.2months), and the median OS was 22.6 months (95% CI, 15.4 – 29.8 months) with good tolerability in anthracycline and taxane pretreated MBC patients. Based on these results, we planned to conduct a multicenter, randomized phase III study which assesses the efficacy of irinotecan and capecitabine combination therapy compared with capecitabine alone in patients with anthracycline and taxane resistant MBC.
Methods: In this trial, patients with HER2 normal tumor who previously received anthracycline and taxane based chemotherapies are enrolled. Eligible patients are randomly assigned in a 1:1 ratio to receive irinotecan plus capecitabine or capecitabine alone. The primary end point of this trial is PFS and a total number of accrual patients will be 222. Randomization is done using a random block size permutation method and stratified by hormone receptor status (negative vs. positive), first line vs. ≥second lines, visceral metastasis (negative vs. positive). Patients receive irinotecan at 80 mg/m2 on day 1 and 8 every 3 weeks and capecitabine 1000mg/m2 bid from day 1 to day 14 every 3 weeks. In control arm, patients receive capecitabine 1250mg/m2 bid from day 1 to day 14 every 3 weeks. Response will be assessed using RECIST1.1 criteria and toxicity will be graded according to NCI-CTCAE 4.0 criteria. Study Status: A total of 107 patients consented for the study since June 2011, and accrual is ongoing. Clinical trial information: NCT01501669.

Abstract
Abstract
Background: The breast cancer-related lymphedema (LE) has been known to be closely related to axillary lymph nodes dissection (ALND), chemotherapy, and radiation therapy. In this study, we evaluated whether the sequence of systemic chemotherapy and surgery could be a predictive factor in stage II/III breast cancer.
Methods and Materials: A total of 867 patients with stage II/III breast cancer, who underwent curative surgery with adequate systemic therapy from 2004 to 2009, were retrospectively analyzed. Adjuvant chemotherapy (ACT) was performed in 571 patients (65.9%) and preoperative systemic chemotherapy (PSC) in 296 (34.1%). We evaluated the incidence of LE by clinicopathologic factors and treatments.
Results: At a median follow-up of 5.1 years (range, 3.0-8.3 years), 360 patients (41.5%) had experienced LE, 244 patients have retained LE (permanent LE), and 116 patents were normalized. The overall 5-year cumulative incidence of LE was 17%. LE occurred in 188 patients (32.9%) in patients with ACT, 172 patients (58.1%) with PSC (P<0.001), permanent LE in 121 (21.2%) with ACT, 123 (41.6%) with PSC (P<0.001), respectively. Multivariate analysis showed that PSC (hazard ratio [HR], 1.65; P<.001), radiotherapy (HR, 2.24; P<0.01), ALND (HR, 1.41; P = 0.04), and nodal stage (HR, 1.93; P = 0.04) were independent risk factors for LE occurrence. For the permanent LE, PSC (HR, 1.44; P = 0.05), radiotherapy (HR, 2.79; P<0.01), ALND (HR, 1.77; P<0.01), and nodal stage (HR, 3.01; P = 0.02) showed the associations.
Conclusions: The risk factors associated with LE were advanced stage, ALND and radiotherapy. PSC was one of predictors for transients LE. However, further evaluation should be done whether it is a risk factor for permanent LE.

Abstract
Background
Immune system has been known to influence the prognosis of breast cancer (BC). However, the relationship between immune modulating factor (PD-L1) and tumor infiltrating lymphocyte (TIL) profiles in breast cancer has yet to be revealed according to breast cancer subtypes. In addition, the effects of circulating cytokines on TILs have not been addressed.
Patients and methods
We investigated the relationship between the profiles of TILs and PD-L1 expression of the primary tumor tissue by immunohistochemistry with clinical outcomes in 253 patients who underwent surgery for early breast cancer at National Cancer Center from January 2001 to December 2005. Besides, the serum cytokines including IL-10, IL-18, IL-6, IFN-g, and TGF-β1 were measured at diagnosis. Clinical data including hormone receptors status, HER2 expression, disease free survival (DFS), and overall survival (OS) were collected.
Results
Median age of patients was 49 years (range, 32-74) and median follow-up was 8.5 years. One hundred eighty five (73.1%) patients had hormone receptor (HR) positive and 101 (39.9%) patients had node positive BC. CD8+ TILs were more abundant in low PD-L1 expressed tumor (P = 0.027), though there was no association between FOXP3+ TILs and PD-L1 expression (P = 0.585). A total number of TILs was higher in HR negative compared with HR positive BC (P = 0.061) and the expression of PD-L1 was more frequent in HR positive BC (P<0.001). In HR negative BC, there was a trend of longer DFS in patients with higher CD8+ TILs and low PD-L1 expression (P = 0.097). However, such association was not detected in HR positive BC patients. Among serum cytokines we examined, the higher levels of IL-18 were significantly associated with shorter DFS in HR negative BC (P = 0.006). In HR negative BC, higher CD8+ TILs with low PD-L1 expression and lower IL-18 were significantly related with better clinical outcomes when adjusted with other clinical factors (DFS, P = 0.032; OS, P = 0.048).
Conclusions
Lower PD-L1 expression in breast tumor was associated with higher CD8+ lymphocyte infiltration. Especially in HR negative BC, increasing CD8+ TILs with lower PD-L1 expression and lower serum IL-18 level were good prognostic factors. Further validation will be needed to establish the role of immune profiles in BC patients.

Abstract
Abstract
Recent findings suggest that HER2-related molecular markers such as PTEN deletion or downregulation, PIK3CA mutation, truncated HER2 receptor (p95HER2), and tumor HER2 mRNA levels, have the potential to predict anti-HER2 treatment response. We evaluated the distribution of these biomarkers at the time of primary diagnosis and their relationship to responsiveness to lapatinib treatment in the metastatic setting in HER2+ breast cancer patients.
We conducted an observational study of female HER2+ breast cancer patients who were initiated on lapatinib treatment following recurrence or metastases in five Asia Pacific countries. Patients were enrolled between August 2010 and December 2012. Eligible patients had a tumor biopsy specimen available from their primary breast cancer diagnosis or before they started on any anti-HER2 treatment, had not been exposed to more than two lines of anti-HER2 treatment in the metastatic setting or other experimental anti-HER2 treatment, and had no other primary tumor. Biomarkers levels at primary diagnosis were measured; PTEN levels were assessed by immunohistochemistry and PIK3CA mutations were detected by a mass spectroscopy-based approach. The primary endpoint was progression-free survival (PFS) from the initiation of first lapatinib-based regimen given in metastatic setting to disease progression from that regimen or death from any cause. PFS analysis was conducted with a data cut-off date of 31 December 2012.
A total of 162 patients were included in this study and 96% have confirmed HER2+ breast cancer primary tumor. The mean age was 52±10 years and 97% had metastases at study entry, with bone being the most common site of metastasis (48%). About a quarter had PTEN protein loss (24%), 30% had PIK3CA mutation, and 7% had both at primary diagnosis. No significant association was observed between both biomarkers or between each biomarker and estrogen receptor status or HER2 status.

Patients with altered PTEN expression, or PIK3CA mutation showed comparable PFS with lapatinib-based treatment as those with normal PTEN or PIK3CA expression at analysis cut-off date (median PFS 7.5 and 8.5 months respectively vs. 8.9 and 9.0 months respectively; p = 0.502 and p = 0.268 respectively). There remained no significant difference in PFS after having adjusted for significant confounders (HR 1.2 and 1.1 respectively; 95% CI 0.7–1.9 and 0.7–1.8 respectively; p = 0.481 and p = 0.730 respectively). The distribution of p95HER2 expression and tumor HER mRNA levels and their association with PFS will be included at the time of presentation.
Our preliminary findings suggest that PTEN alteration, or PIK3CA mutation may not be predictive of clinical response to lapatinib treatment in HER2+ breast cancer patients. The final PFS results with additional markers will provide more clues regarding their relationship to treatment response.

Abstract
Abstract
Background: S1 and oxaliplatin (SOX) combination chemotherapy is an effective regimen in anthracycline and taxane pretreated metastatic breast cancer (MBC) patients with manageable toxicities (KCSG BR07-03, SABCS 2011 #Abst P3-16-06). The aim of this study was to investigate the association of the single nucleotide polymorphisms (SNPs) and clinical outcome in MBC treated with SOX chemotherapy.
Patients and Methods: A total of 87 MBC patients previously treated with or resistant to anthracycline and taxane chemotherapy were enrolled in this prospective multicenter trial. The patients received S-1 80mg/m2/day (day 1–14) and oxaliplatin 130 mg/m2 (day 1) every 3 weeks till progression. Among the 87 patients, 77 patients were available for SNP analysis. Germline DNA from peripheral blood (PB) mononuclear cells was extracted. SNPs in 4 genes from pathways that may influence cellular sensitivity to S1 and oxaliplatin (TS, ERCC, XPD, and XRCC) were genotyped from PB sample using PCR-restriction fragment length polymorphism.
Results: Overall response rate (RR) was 38.5% (95% CI: 27.7–49.3) and disease control rate was 67.9% (95% CI:57.5–78.3) to SOX. Median time-to-progression (TTP) and overall survival (OS) were 6.0 mo (95% CI: 5.1–6.9 mo) and 19.4 mo (95% CI: not estimated), respectively. XRCC1 Arg194Trp SNP which participates in DNA repair mechanism showed correlation with the clinical outcome. RR was tend to higher in XRCC1 Arg194Trp CC genotype compared with CT or TT genotype (50.0 % vs 35.1% or 12.5%, P = 0.121). TTP of patients with CC genotype in XRCC1 Arg194Trp was significantly longer than the TTP of patients with CT or TT genotype (median TTP: 6.4 mo in CC, 5.9 mo in CT, 3.0 mo in TT, P = 0.007) as well as overall survival (OS) (median OS: not reached in CC, 13.9 mo in CT, 7.1 mo in TT, P = 0.006). After adjusting for hormone receptor status, performance status, and visceral involvement, prognostic value of XRCC1 Arg194Trp SNP remained significant (Hazard Ratio=1.322 and 4.484, P = 0.016). Other SNPs were not significantly associated with survival or toxicities.
Conclusion: XRCC1 Arg194Trp SNP is associated with clinical outcome of MBC patients treated with SOX chemotherapy. Further studies of the relationship between germline polymorphisms in XRCC1 and functional mechanism researches are warranted.

Abstract
BACKGROUND In Asia, large-scale studies on anti-HER2 treatment in HER2-positive breast cancer patients with brain metastases are limited. We studied the treatment patterns of these patients in Asia to evaluate the impact of anti-HER2 treatment on the time to occurrence of brain metastases (TTBM) and survival after brain metastasis (BM). METHODS A retrospective study of HER2-positive breast cancer patients diagnosed with BM between January 2006 and December 2008 in six Asian countries was conducted. Demographics, tumour characteristics, treatment details, and events dates were collected from medical records. RESULTS Data from 280 patients were analysed. Before BM, 63% received anti-HER2 treatment. These patients had significantly longer TTBM than those without anti-HER2 treatment (median 33 vs 19 months; P<0.002). After BM, 93% received radiotherapy, 57% received chemotherapy, and 41% received anti-HER2 treatment (trastuzumab and/or lapatinib). Use of both anti-HER2 agents, primarily sequentially, after BM demonstrated the longest survival after BM and was associated with a significant survival benefit over no anti-HER2 treatment (median 26 vs 6 months; hazard ratio 0.37; 95% CI 0.19-0.72). CONCLUSION Anti-HER2 treatment before BM was associated with longer TTBM. Anti-HER2 treatment after BM was associated with a survival benefit, especially when both trastuzumab and lapatinib were utilised.

Abstract
BACKGROUND We investigated the relationship between resumption or persistence of menstruation after cytotoxic chemotherapy (RM) and disease-free survival (DFS) in premenopausal patients with early breast cancer. METHODS Medical records from 872 patients who received cytotoxic chemotherapy for stage I to III breast cancer were retrospectively reviewed. RESULTS The median patient age was 41 years (range, 21-54) and the median follow-up duration was 6.2 years (range, 0.7-10.4). Six hundred ninety-two patients (79.4%) were hormone receptor (HR) positive and the majority of these received tamoxifen therapy after completing chemotherapy. The chemotherapy-induced amenorrhea (CIA) rate was 76.7% (n = 669), and 51.8% (n = 452) experienced RM during the follow-up period. One hundred twenty-one (13.9%) patients had persistent menstruation without CIA. DFS was significantly affected by younger age at diagnosis (≤35 years) (P = 0.013), tumor size > 2 cm (P < 0.001), node positivity (P < 0.001), HR negativity (P < 0.001), HER2 positivity (P = 0.010), and RM (P < 0.001). HR negativity [hazard ratio 1.7, 95% confidence interval (CI) 1.2-2.4, P = 0.006], tumor size > 2 cm (hazard ratio 2.1, 95% CI 1.4-3.0, P < 0.001), node positivity (hazard ratio 3.0, 95% CI 2.0-4.7, P < 0.001), and RM (hazard ratio 1.8, 95% CI 1.2-2.7, P = 0.004) remained significant factors for DFS on multivariate analysis. CONCLUSIONS A considerable proportion of premenopausal patients treated with chemotherapy experienced RM after CIA. RM was a poor prognostic factor for DFS in premenopausal patients with early breast cancer.

Abstract
Abstract
It has been known that young breast cancer patients have worse outcomes compared with older premenopausal or postmenopausal patients. Survival difference between young and older breast cancer patients is evident only in hormone receptor positive breast cancer regardless of tamoxifen treatment according to our previous report. However, the biology of aggressiveness and endocrine resistance of breast cancer in very young women is largely unknown. The purpose of this study is to find molecular characteristics of hormone receptor positive breast cancers of very young age women (<35) compared with those of older premenopausal women.
We extracted mRNA from fresh frozen hormone receptor positive primary breast cancer tissues of 24 young age breast cancer patients (<35 years) and 31 older premenopausal women (40 to 49 years) by standard method. All tumor specimens analyzed contained more than 50% tumor cells. Hormone receptor status was determined by immunohistochemistry (IHC). Gene expression microarray experiment was done in the 55 samples using Illumina HumanRef-8 v3 Expression BeadChip (Illumina, Inc., San Diego, CA). Functional and pathway analysis of differentially expressed genes were done using DAVID (http://david.abcc.ncifcrf.gov/home.jsp) and Ingenuity pathway analysis (IPA, http://www.ingenuity.com). Ki-67 assay was done using IHC in 4,957 ER+ breast cancer patients of Seoul National University cohort and 1,863 ER+ patients from National Cancer Center, Korea.
355 genes were upregulated (>1.5 fold) and 209 genes were down-regulated in breast cancer tissues of young age patients (<35) compared with those of older patients. In pathway analysis of the highly expressed genes in young patients, cell cycle function and pathway was significantly activated. The genes of central role in this pathway were MYC and CCND1. In IHC assay for 4,957 ER+ Seoul National University dataset, the proportion of high Ki-67 expression (>=10%) was positively correlated with decreasing age: 26.4%, 24.0%, 21.3%, 14.8%, 12.0% of women aged <30, 30–34, 35–39, 40–49, 50–59, respectively (p<0.001). The same correlation pattern between younger age and high Ki-67 expression was also seen in another 1,863 patient cohort.
In conclusion, we showed that genes involved in cell cycle pathway were upregulated in very young age (<35) ER+ breast cancer using microarray study. It was validated in large data set using Ki-67 IHC assay. High proliferation and fast cell cycle could be a mechanism of worse outcome and tamoxifen resistance of ER+ very young age breast cancer patients.

Abstract
Abstract
Background
Oxaliplatin, a platinum analogue, is an active drug in advanced anthracycline and taxane-pretreated breast cancer patients as a single agent and with 5-fluorouracil (5-FU) combination. TS-1 was developed by the scientific theory of both potentiating antitumor activity of 5-FU and reducing gastrointestinal toxicity. This trial was performed to evaluate the efficacy and safety of TS-1 in combination with oxaliplatin in metastatic breast cancer (MBC) patients previously treated with anthracycline and taxane chemotherapy.
Methods: Between October 2007 and October 2009, MBC patients were enrolled in this prospective multicenter trial. Eligible criteria included age ≥18 years, at least one measurable lesion, prior treatment with anthracycline and taxane chemotherapy, and ECOG Performance Status 0–2. TS-1 40 mg/m2 b.i.d. on days 1–14 with oxaliplatin 130 mg/m2 on day 1 were administered every 3 weeks till disease progression. Primary end-point was response rate, and secondary end-points were time-to-progression (TTP), overall survival (OS), duration of response (DOR) and toxicities. Response was evaluated every 6 weeks according to the RECIST criteria v. 1.0 and toxicity was assessed with NCICTCAE v.3.0.(ClinicalTrials.gov identifier NCT00527930).
Results: A total of 87 patients were enrolled. Median age was 48 years (range 30–71 years). Nineteen patients (21.8%) had de novo stage IV and 68 patients (78.2%) had recurrent disease. Thirty-five patients (40.2%) received two-lines of prior chemotherapy in palliative setting. Forty-eight patients (55.2%) had ≥ 3 disease sites. Fifty-four patients (62.1%) were hormone receptor positive, and 25 patients (28.7%) were triple negative. Five patients received prior anti-HER2 therapy. A total of 525 cycles were administered (median 6 cycles, range: 1 ∼ 22+ cycle). In per-protocol analysis, overall response rate was 38.5% (95% CI: 27.7−49.3) (CR 0%, PR 38.5%) and disease control rate (CR, PR, and SD) was 67.9% (95% CI: 57.5−78.3). Median TTP, OS, and DOR were 6.0 months (95% CI: 5.1−6.9 months), 19.4 months (95% CI: not estimated), 6.6 months (95% CI: 3.7−9.6 months), respectively. RR was not different by triple negativity (39.1% in TNBC vs. 38.2% in non-TNBC, P=0.361). TTP was not different according to the number of prior chemotherapy regimens. Reported grade 3 or 4 toxicities (per cycle) were neutropenia (10.3%), thrombocytopenia (5.5%), diarrhea (1.9%), vomiting (1.9%), and stomatitis (0.2%). There was no treatment-related death.
Conclusions: SOX is an effective regimen in anthracycline and taxane pretreated MBC patients with manageable toxicities.

Abstract
Abstract
Background We addressed the progression free survival of brain metastasis (PFS_BM) in metastatic breast cancer (MBC) patients treated by whole brain radiotherapy (WBRT) for brain metastasis (BM). In addition, we investigated predictive and prognostic factors for the PFS_BM and OS_BM.
Patients and methods A total of 212 patients with BM, treated by WBRT at the National Cancer Center between January 2000 and December 2010 were reviewed. The PFS_BM was defined as the time interval from the date of start of WBRT to the date of a progression of metastatic lesions in the brain or death or last follow-up.
Results The median age of patients was 45 years (range, 22–72 years) and the median time to brain metastasis was 12.7 months (range, 0.0−72.8 months).
Of all patients, 50 (23.6%) patients were hormone receptor (HR) positive and 104 (49.1%) HER2 positive. Six patients received a surgery or a focal radiotherapy for metastatic lesions prior to WBRT. Seventy one (33.4%) patients had well controlled extracranial systemic disease (CR+PR+SD) when brain metastasis was diagnosed. The median survival after BM (OS_BM) was 5.4 months (95% CI, 4.4−6.4 months) and approximately 14.6% of patients died mainly of progressive brain metastasis. The PFS_BM was significantly affected by poor performance status (PS ≥3) (P<0.001), uncontrolled systemic disease status (P=0.029), disease free interval (DFI) < 2 years (P=0.011), no chemotherapy after BM (P<0.001), and HER2 positivity (P=0.002). Of those, poor PS, no chemotherapy after BM, and uncontrolled systemic disease status were remained important factors on a multivariate analysis. In terms of OS_BM, poor PS (P<0.001), older age (P=0.005), number of systemic metastatic sites >3 (P<0.001), uncontrolled systemic disease status (P<0.001), disease free interval (DFI) < 2 years (P=0.014), no chemotherapy after BM (P<0.001), and visceral involvement (P=0.009) were significant factors. Of those, poor PS (P<0.001), uncontrolled systemic disease status (P<0.001), and no chemotherapy after BM (P<0.001) were important factors for shorter OS_BM when adjusted with other factors.
Conclusions Uncontrolled extracranial systemic disease status, no chemotherapy after BM, and poor PS were significant factors for shorter PFS_BM and overall survival after brain metastasis.

Abstract
Abstract
Purpose Invasive lobular carcinoma (ILC) is known to be the second most frequent histologic subtype, occupying 10% of invasive breast cancer in the Western countries. The present study was designed to assess the clinical characteristics and outcomes of ILC compared to general invasive ductal carcinoma (IDC) and the luminal A subtype (LA-IDC).
Methods The study population included d 2916 patients with invasive breast cancer consecutively diagnosed at the National Cancer Center, Korea between 2001 and 2008. The clinicopathological characteristics and clinical outcomes were retrospectively reviewed.
Results There were 83 pts (2.8%) diagnosed with ILC and 1,088 pts (37.3%) with LA-IDC. Mean age was 48.2 years of all patients, 48.3 years of ILC group and 47.9 years of LA-IDC group. The ILC patients presented with a larger tumor size (≥T2, 59.8% vs. 38.8%, P=0.001), lower histologic grade (HG 1 or 2, 90.4% vs 64.4%, P<0.001), more often estrogen receptor (ER) and progesterone receptor (PgR) positivity (ER+, 90.4% vs. 64.4%, P<0.001; PgR+, 71.1% vs. 50.1%, P<0.001), HER2 negativity (97.5% vs. 74.9%, P<0.001), lower Ki-67 expression (10.3% ± 10.6% vs. 20.6% ± 19.8%, P<0.001), and luminal A subtypes (91.4% vs. 51.2%, P<0.001) compared to the IDC group. Six (7.2%) ILC patients and 359 (12.7%) IDC patients developed disease recurrence with a median follow-up of 56.4 months (range 4.9-136.6 months). Although ILC showed similar prognosis to IDC in general (5-year DFS rate, 91.7% in ILC vs. 87.4% in IDC, P=0.31; 5-year OS rate, 93.6% in ILC vs. 92.5% in IDC, P=0.38), its outcome was closer to LA-IDC, and better than non LA-IDC (LA-IDC (ref); ILC, HR 0.77 in recurrence, 95% CI 0.31-1.90, P=0.57; HR 0.75 in death, 95% CI 0.18-3.09, P=0.70; non LA-IDC, HR 1.69 in recurrence, 95% CI 1.23-2.33, P=0.001; HR 1.50 in death, 95% CI 0.97-2.33, P=0.07) in univariate and multivariate analysis.
Conclusions ILC is a very rare histologic subtype of breast cancer in Korea compared to the Western countries and has distinctive clinicopathological characteristics similar to those of LA-IDC. Acknowledgement: supported by NCC grant #0910320

Abstract
Abstract
Background: The L-Expanded Access Program (LEAP) was designed to provide access to L/C for HER2+ patients (pts) who previously received anthracycline, taxane, and trastuzumab. In earlier registration trial, CNS metastases occurred in fewer women receiving L/C therapy compared with C alone. Although L therapy has shown efficacy in brain metastasis (BM), it has not been well elucidated in relationship with the outcomes of systemic disease.
Patients and methods : Enrollment in LEAP lasted between Jan. 2007 and Apr. 2008 at 6 centers in Korea. Exploratory analysis on clinical outcomes of brain metastasis was performed.
Results: Total 187 pts enrolled in LEAP. The median treatment duration of all pts was 19.0 weeks (range, 1.4 — 146.9). The median progression free survival and overall survival (OS) of all pts were 20.0 (95% confidence interval [CI]= 18.6-24.0) and 60.0 (95% CI= 50.3-72.7) weeks, respectively. All patients received prior trastuzumab therapy, and 48.7% received prior capecitabine. Among 58 enrolled pts who had BM diagnosed before start L/C therapy, 55 pts were included for the analysis excluding 3 pts (1-consent withdrawal and 2-<3 weeks trial). Fifteen pts had single BM. Majority were HER2 IHC 3+ or FISH +, and 48% were both ER/PR-. Prior to EAP enrollment, 35 pts underwent whole brain radiation, 10 pts SRS or gamma knife, 3 pts local excision, 1 pt had leptomeningeal disease only receiving intrathecal therapy, and 6 pts did not receive local CNS therapy. Four pts underwent more than one modality of local CNS therapy. Of 50 pts evaluable for response, 9.1%, achieved or remained CR; 45.5% had some degree of shrinkage of BM; 14.5%, no change (SD) ≥6mo; 7.3%, SD <6mo; 14.5% developed PD or recurrence of BM. Median TTP of pts (n=53) with BM on L/C therapy was 30.7 weeks (95% CI=25.0-35.1) and median OS (n=55) was 53.1 weeks (95% CI= 42.3-78.0). From the multivariate analysis, TTP of BM was significantly associated with response of BM (HR, 20.3, 95% CI=7.3-56.0, P<0.001). OS of pts with BM was significantly longer with tumors of ER or PR+ status (HR, 3.10, 95% CI=1.55-6.19, p=0.0014), and who responded in systemic disease and brain (HR, 4.5, 95% CI= 2.2-9.2, P<0.0001). Of remaining 129 pts, 8 pts (6.2%) developed new BM on EAP.
Conclusion: Overall survival of patients with brain metastasis who received lapatinib plus capecitabine was prolonged specifically in responders of both brain and extracranial disease. Patients with hormone receptor positive tumors had longer survival compared with those of hormone receptor negative disease.

Abstract
Abstract
Purpose: One of substudies of the prospective trials aimed to evaluate the usefulness of serial [18F] 2-fluoro-2-deoxy-D-glucose-positron emission tomography ([18F] FDG-PET) for predicting pathological complete response (pCR) in stage II/III breast cancer with preoperative chemotherapy (PST).
Methods: Serial PET was undertaken in 57 breast cancer patients enrolled in three different neoadjuvant trials: 35 patients from a phase II study with paclitaxel/gemcitabine/trastuzumab with ClinicalTrial.gov NCT 00532857, 9 patients from a phase Ib study with paclitaxel/gemcitabine/lapatinib with ClinicalTrial.gov NCT 01133912, and 13 patients from a phase Ib with paclitaxel/gemcitabine/sunitinib with ClinicalTrial.gov NCT0 1070706. All patients received 6 cycles of PST followed by surgery and radiotherapy. We assessed the peak standardized uptake value (SUVp) in the primary tumor at the baseline and after the 2nd cycle (37 patients) or after completion (20 patients) of 6 cycles of PST, and calculated the reduction rate (RR) of the SUVp. Pathological response was classified into pCR and non-pCR. To compare the mean of SUVp and RR of SUVp between different response groups, two-way tables and chi-square tests were used
Results: Fifteen (40.6%) of 37 patients who took repeat PET after the 2nd PST and 15 (75%) of 20 patients after completion of PST achieved a pCR with overall pCR rate of 52.6% in the primary tumor. In patients with repeat PET after the 2nd PST, post-treatment SUVp and RR of the SUVp in primary tumors were significantly different by the pathological response (post-treatment SUVp, 1.54 ± 0.63 in pCR vs 2.54 ± 1.06 in non-pCR, P=0.002; RR of the SUVp, 79.2% ± 11.9% in pCR vs 68.9% ± 15.4% in non-pCR, P=0.03). However, in patients with repeat PET after completion of PST, there were no statistical differences of these values (post-treatment SUVp, 1.09 ± 0.63 in pCR vs 1.29 ± 0.36 in non-pCR, P=0.42; RR of the SUVp, 83.7% ± 14.0% in pCR vs 67.5% ± 21.1% in non-pCR, P=0.17)
Conclusions: This study demonstrated that repeat PET after the 2nd cycle of PST, not after completion of PST could predict pCR in stage II/III breast cancer with preoperative chemotherapy. Acknowledgement NCC Grant #0910320.

Abstract
BACKGROUND Although high soy consumption may be associated with lower breast cancer risk in Asian populations, findings from epidemiological studies have been inconsistent. OBJECTIVE We investigated the effects of soy intake on breast cancer risk among Korean women according to their menopausal and hormone receptor status. METHODS We conducted a case-control study with 358 incident breast cancer patients and 360 age-matched controls with no history of malignant neoplasm. Dietary consumption of soy products was examined using a 103-item food frequency questionnaire. RESULTS The estimated mean intakes of total soy and isoflavones from this study population were 76.5 g per day and 15.0 mg per day, respectively. Using a multivariate logistic regression model, we found a significant inverse association between soy intake and breast cancer risk, with a dose-response relationship (odds ratios (OR) (95% confidence interval (CI)) for the highest vs the lowest intake quartile: 0.36 (0.20-0.64)). When the data were stratified by menopausal status, the protective effect was observed only among postmenopausal women (OR (95% CI) for the highest vs the lowest intake quartile: 0.08 (0.03-0.22)). The association between soy and breast cancer risk did not differ according to estrogen receptor (ER)/progesterone receptor (PR) status, but the estimated intake of soy isoflavones showed an inverse association only among postmenopausal women with ER+/PR+ tumors. CONCLUSIONS Our findings suggest that high consumption of soy might be related to lower risk of breast cancer and that the effect of soy intake could vary depending on several factors.

Abstract
Abstract
Background :It is known that cancer patients in healthy hepatitis B viral (HBV) carrier status are prone to develop hepatic dysfunction during cytotoxic chemotherapy. The objectives of this study were to determine the frequency of healthy HBV carrier status and subsequent viral reactivation resulting in hepatic dysfunction during cytotoxic chemotherapy, and its significance in early breast cancer patients.Methods :Among 3,433 patients with operable breast cancer diagnosed at the National Cancer Center, Korea between January 2001 and March 2009, 3,337 patients were tested for HBsAg. Retrospectively, medical records were reviewed for 139 (4.2%) patients who were positive for HBs Ag.Results :Of 139 patients, 112 patients received anthracycline or taxane based neoadjuvant (n=25) or adjuvant (n=87) combination chemotherapy. Prophylactic lamivudine therapy was administered in 33 patients (29.5%).Thirty of 112 (26.8%) patients developed reactivation of HBV with deterioration of hepatic function during chemotherapy. The rate of reactivaton was not different with or without further taxane therapy (43% vs. 44%, p=0.408).Although there was no significant difference in the rate of chemotherapy delay between two groups, the incidence of early termination of planned chemotherapy was higher in B viral reactivation group (23.3% vs. 4.9%, p=0.008). Within a median follow-up duration of 39 mo (range 1 mo to 95 mo), the rate of disease recurrence was comparable between two groups (10% vs. 18.3%, p=0.390).Lamivudine prophylaxis decreased the rate of HBV reactivation without statistical significance (15.1% vs. 35.4%, p=0.101). Despite more patients without prophylaxis developed G 3/4 AST/ALT elevation (40% vs. 84%, p=0.068), the majority of patients recovered to G 1/2 AST/ALT level within 12 months with anti-viral or supportive treatment (0% vs. 14.3%, p=1.00). One patient without lamivudine prophylaxis developed fulminant hepatic failure after 3rd cycles of neo-adjuvant chemotherapy and received living donor liver transplantation. After that, she received radical mastectomy and maintained adjuvant anti-hormonal therapy.Conclusions :Although lamivudine prophylaxis in HBV healthy carrier decreased the rate of viral reactivation during neo- or adjuvant chemotherapy, the majority of patients irrespective of prophylaxis recovered hepatic function in a year with conservative treatment. Early detection and intensive supportive care are as important as anti-viral prophylaxis in HBV healthy carrier when treated with cytotoxic chemotherapy.

Abstract
Abstract
Background: We aimed to evaluate the clinicopathologic factors affecting locoregional recurrence (LRR) in potentially operable breast cancer patients receiving preoperative systemic chemotherapy (PST).Methods: We reviewed the records of 316 breast cancer patients treated with PST (doxorubicin/cyclophosphamide, 101; docetaxel /capecitabine, 103; paclitaxel/gemcitabine, 43; doxorubicin/docetaxel, 69) followed by surgery and adjuvant radiotherapy between 2002 and 2006. The majority of patients had clinical positive axillary lymph nodes. To define the prognostic factors for LRR, age, clinical stage, hormone receptor (HR) and HER2 status, clinical and pathologic response, type of operation, pathological characteristics including tumor size, tumor grade, nodal status, number of positive axillary nodes, size of metastatic lymph node and status of resection margin and tumor multiplicity before and after PST were analyzed.Results: Overall 52 patients (16.5%) in the primary tumor and 87 patients (27.5%) in the axillary nodes achieved a pathologic complete response (pCR), and 206 patients (65.2%) underwent breast conserving surgery (BCS). With a median follow-up of 52.4 month (range: 4.7 - 89.4), total 18 (5.7%) patients developed LRR; 2 of 110 (1.8%) patients with mastectomy vs. 16 of 206 (7.7%) patients with BCS (p=0.04). Other significant factors in the univariate analysis were clinical T stage, HR status, clinical response and tumor multiplicity. A pCR in the primary tumor or node was not a prognostic factor for LRR in this study. In multivariate analysis, clinical T stage (T3/4, HR 7.8; 95% CI, 2.33-26.24; P=0.001), hormone receptor status (negative, HR 6.2; 95% CI, 1.91-20.22; P=0.002) and type of surgery (BCS, HR 9.5; 95% CI, 1.97-46.37; P=0.005) were independent prognostic factors. Among patients with BCS, advanced clinical T stage (HR 12.4; 95% CI, 3.45-44.56; P<0.001), negative hormone receptor (HR 4.74; 95% CI, 1.33-16.96; P=0.02), non-responding disease (HR 6.54; 95% CI, 1.07-40.12; P=0.04) and multiple tumors (HR 4.36; 95% CI, 1.06-17.90; P=0.04) developed more frequent LRR.Conclusions: Significantly more patients with advanced clinical T stage, negative HR status and BCS developed LRR in operable breast cancer treated with PST. Moreover, in patients with BCS after PST, clinically non-responding disease and multiple tumors showed unfavorable prognosis besides the larger tumors and negative hormone receptor.Partly supported by NCC Grant No 0610240
