Background: Phyllodes tumor of the breast (PTB) is a rare tumor. PTB exist in benign (BPTB), borderline, and malignant (MPTB) subtypes. Local recurrence (LR) is the most common site of relapse. Treatment of early-stage PTB consists of local excision (LE), with free margins of resection (MR) or mastectomy (MM). Patients and Methods: We conducted a retrospective study of all consecutive patients with early-stage PTB treated with breast surgery at our institution for 8 years, in order to describe the outcome and the clinical behavior of PTB. The primary end-points of our study were disease-free survival (DFS) and overall survival (OS). Secondary endpoints were the description of the pathological features, the site of first recurrence (SFR), and prognostic factors. Results: We included a total of 16 patients. Four patients had BPTB, and 12 had MPTB. Median age was 50 years (21-81), and 62.5% was postmenopausal. Five patients (31.25%) were treated with LE and 11 (68.75%) with MM. Median tumor size was 3.6 cm (1.3-19), median mitosis/high-power field was 10 and 6.25% had positive-MR. With a median follow-up of 97 months, 5-year DFS probability was 65%. There were 5 recurrences (31.25% of all patients), all of them in the malignant subtype. 5-year OS probability was 66%. The most common SFR was LR (62.5%), followed by lung (18.75%) and bone (18.75%) metastases. In univariate analysis, T> 4.5 cm (p=0.004) and positive-MR (p=0.038) were associated with an increased risk of relapse and death. Conclusion: BPTB is associated with a good prognosis after adequate surgery. However, MPTB has a high risk of relapse and death after surgery, and this risk increases with larger tumors and positive-MR.

Risk Of Relapse

AbstractLow-grade and early-stage endometrioid endometrial carcinomas (EECs) have an overall good prognosis but biomarkers identifying patients at risk of relapse are still lacking. Recently, CTNNB1 exon 3 mutation has been identified as a potential risk factor of recurrence in these patients. We evaluate the prognostic value of CTNNB1 mutation in a single-centre cohort of 218 low-grade, early-stage EECs, and the correlation with beta-catenin and LEF1 immunohistochemistry as candidate surrogate markers. CTNNB1 exon 3 hotspot mutations were evaluated by Sanger sequencing. Immunohistochemical staining of mismatch repair proteins (MLH1, PMS2, MSH2, and MSH6), p53, beta-catenin, and LEF1 was performed in representative tissue microarrays. Tumours were also reviewed for mucinous and squamous differentiation, and MELF pattern. Nineteen (8.7%) tumours harboured a mutation in CTNNB1 exon 3. Nuclear beta-catenin and LEF1 were significantly associated with CTNNB1 mutation, showing nuclear beta-catenin a better specificity and positive predictive value for CTNNB1 mutation. Tumours with CTNNB1 exon 3 mutation were associated with reduced disease-free survival (p = 0.010), but no impact on overall survival was found (p = 0.807). The risk of relapse in tumours with CTNNB1 exon 3 mutation was independent of FIGO stage, tumour grade, mismatch repair protein expression, or the presence of lymphovascular space invasion. CTNNB1 exon 3 mutation has a negative impact on disease-free survival in low-grade, early-stage EECs. Nuclear beta-catenin shows a higher positive predictive value than LEF1 for CTNNB1 exon 3 mutation in these tumours. Graphical abstract

PURPOSE Adjuvant tamoxifen has been shown to reduce relapse and mortality among node-positive post-menopausal breast cancer patients. The value of adding chemotherapy to tamoxifen is controversial. PATIENTS AND METHODS Between July 1986 and April 1993, 1,266 postmenopausal breast cancer patients with node-positive disease were randomly assigned to receive one of four adjuvant therapy regimens: (A) tamoxifen alone for 5 years; (B) tamoxifen plus three courses of early cyclophosphamide, methotrexate, and fluorouracil (CMF) on months 1, 2, and 3; (C) tamoxifen plus delayed single courses of CMF on months 9, 12, and 15; (D) tamoxifen plus early and delayed CMF on months 1, 2, 3, 9, 12, and 15. The two-by-two factorial design allowed two direct comparisons: early CMF (B and D) versus no early CMF (A and C), and delayed CMF (C and D) versus no delayed CMF (A and B). Estrogen receptor (ER) status was known for all patients and was used to stratify the randomization. A total of 1, 212 patients (96%) were eligible and assessable. The median follow-up duration was 60 months. RESULTS The results of the two-by-two factorial comparisons were as follows: (1) early CMF added to tamoxifen significantly improved 5-year disease-free survival (DFS; 64% v 57%; hazards ratio [HR], 0.79; 95% confidence interval [CI], 0.66 to 0.95; P = .01); and (2) delayed CMF added to tamoxifen did not improve DFS (5-year DFS, 61% v 60%; HR, 0.97; 95% CI, 0.81 to 1.17; P = .77). For patients with ER-positive tumors, the addition of CMF, either early or delayed or both, reduced the relative risk of relapse by 22% to 36%. In contrast, for patients with ER-negative tumors, tamoxifen with delayed CMF was associated with a nonsignificant increased risk of relapse (HR, 1.27; 95% CI, 0.92 to 1.76; P = .15). CONCLUSION Postmenopausal patients with node-positive breast cancer should be offered combination chemotherapy in addition to tamoxifen. Tamoxifen should not be initiated before CMF, as this might be detrimental, especially for patients with ER-negative tumors.

Background. The aim of this study was to analyse whether the level of tissue inhibitor of metalloproteinases (TIMP) 1 is associated with the tumour response and survival to preoperative radiochemotherapy in rectal cancer patients. Patients and methods. Ninety-two patients with histologically confirmed non-metastatic rectal cancer of clinical stage I- III were treated with preoperative radiochemotherapy, surgery and postoperative chemotherapy. Plasma TIMP-1 concentrations were measured prior to the start of the treatment with an enzyme-linked immunosorbent assay (ELISA). Results. Median follow-up time was 68 months (range: 3-93 months) while in survivors it was 80 months (range: 68-93 months). The 5-year locoregional control (LRC), disease-free survival (DFS), disease-specific survival (DSS) and overall survival (OS) rates for all patients were 80.2%, 56.4%, 63.7% and 52.2%, respectively. The median TIMP-1 level was 185 ng/mL (range: 22-523 ng/mL) and the mean level (±standard deviation) was 192 (±87) ng/mL. Serum TIMP-1 levels were found to be significantly increased in patients with preoperative CRP>12 mg/L and in those who died from rectal cancer or had cT4 tumours. No correlation was established for age, gender, carcinoembriogenic antigene (CEA) level, platelets count, histopathological grade, response to preoperative therapy, resectability and disease reappearance. On univariate analysis, various parameters favourably influenced one or more survival endpoints: TIMP-1 <170 ng/mL, CRP <12 mg/L, platelets count <290 10E9/L, CEA <3.4mg/L, age <69 years, male gender, early stage disease (cN0 and/or cT2-3), radical surgery (R0) and response to preoperative radiochemotherapy. In multivariate model, LRC was favourably influenced by N-downstage, DFS by lower CRP and N-downstage, DSS by lower CRP and N-downstage and OS by lower TIMP-1 level, lower CRP and N-downstage. Conclusions. Although we did not find any association between pretreatment serum TIMP-1 levels and primary tumour response to preoperative radiochemotherapy in our cohort of patients with rectal cancer, TIMP-1 levels were recognized as an independent prognostic factor for OS in these patients.

Prospective studies have shown equal outcomes after mastectomy or breast conservation in patients with invasive breast cancer; however, many of these studies excluded elderly patients. We identified patients in their eighties and nineties with clinical stage 0 to II breast cancer undergoing mastectomy or lumpectomy with or without radiation from the prospective sentinel lymph node database at Wake Forest Baptist Health and analyzed their treatment and survival. Of 92 patients, 24 (26.1%) underwent mastectomy, 22 (23.9%) lumpectomy with radiation, and 46 (50.0%) lumpectomy alone. Significant differences were noted in tumor size (P = 0.018), nodal status (P = 0.013), and stage (P = 0.011) between the groups. Only 7.6 per cent of patients had chemotherapy, whereas 51.1 per cent took antiestrogen therapy. Recurrence occurred in 11 patients. In univariate analysis, overall survival did not differ by surgery. Age was the only factor that increased risk of death (HR = 1.19, P = 0.028). In this age group, neither tumor factors nor the type of local treatment significantly influenced overall survival. Octogenarians and nonagenarians with early-stage breast cancer undergoing breast-conserving surgery with or without radiation have equivalent survival to patients having a mastectomy.

4088 Background: LMTK3 is an estrogen receptor α (ERα) regulator. Recent studies show that [rs808419(r8) and rs9989661(r9)] and LMTK3 expression are prognostic in breast and colon cancers. Our group demonstrated that r9AA is associated with shorter time to recurrence in Caucasian(C) and Hispanic(H) females(F) with GAC. We investigated the significance of LMTK3 polymorphism in J PTS with GAC. Methods: Blood or tissue samples of 169 J PTS who had surgery with/without adjuvant chemotherapy (ACT) were analyzed. Genomic DNA was extracted using the QIAmp kit; all samples were analyzed using PCR-based direct DNA-sequencing. The endpoints of the study were disease-free survival (DFS) and overall survival (OS). Kaplan-Meier curves and log-rank test were used for univariate analysis. Multivariate analysis was performed to test the interaction between polymorphism and gender adjusting for other variables. Results: 60 F and 109 males were enrolled in this study, 17% stage(s) IB, 31% s II, 36% s III, 17% s IV (AJCC-6). The median age was 67(31-88). 65% of PTS received S-1 based ACT. Median follow-up was 4 years(ys). Prognosis was worse in men with r9 AA than AG/GG, at 1 year 67% (95% CI 40-83%) with AA vs 99% (95% CI 91-99%) of AG/GG were alive (p= 0.039). Median survival was not reached in the AG/GG group; in the AA group median DFS and OS was 1yr (p= 0.03) and 2ys (p= 0.039) respectively. In the multivariate analysis adjusting for s, age, and ACT, males carrying AA had increased risk of disease recurrence (HR 3.84 95%CI 1.86-7.92, p< 0.001) and dying (HR 3.47 95%CI 1.58-7.62 p=0.002) compared to those with AG/GG (HR=1, reference). Conclusions: r9 AA was associated with significantly worse DFS and OS in J male with GAC. These results confirm our previous findings that LMTK3 is an independent prognostic factor for localized GAC; interestingly the relationship between gender and prognostic significance is the opposite in J vs. C/H. The gender disparity can be due to the differences in the etiology (histological subtypes), management strategies, allele frequency, and degree of estrogen exposure in the two populations. Additional studies are warranted to identify the underlying biological mechanism.

e15573 Background: Stage IC patients are at an increased risk of recurrence and overall worse prognosis compared with stage IA and IB patients. Adjuvant chemoherapy is utilized based on specific pathologic factors. The objective of this study is to evaluate treatment outcomes at a single institution in patients with 1988 FIGO stage IC endometrial adenocarcinoma. Methods: Records of the patients with FIGO stage IB (formerly IC) endometrial cancer were retrospectively evaluated. All patients were initially treated surgically with comprehensive staging lymphadenectomy. Results: A total of 85 patients were included. Patient and tumor characteristics are shown in the table. Median age of the patients was 60 (range 27-95). Fifty-nine patients had at least one co-morbid disease. Complete surgical staging including pelvic and paraaortic lymph node dissection was performed in all the patients. Sixteen patients (19%) received adjuvant chemotherapy, including 6 patients with serous cancer and one patient with small cell cancer. Paclitaxel/carboplatin was the preferred regimen in Median follow up was 30 months (range 10-61 months). Seven patients (8%) relapsed and 4 patients (5%) died on follow up. 5 year disease free survival was 89% and overall survival was 95%. One of the 16 patients (6.2%) who received chemotherapy and 6 of the 69 patients (8.7%) who did not receive relapsed/died on follow up. Survival analysis was not performed because of the low number of events in both groups. Conclusions: We found similar rates of recurrence and death with previous studies in stage IC endometrial cancer. Complete surgical staging is the mainstay of treatment. Marginally lower recurrence rate in chemotherapy treated patients delineate the need for prospective randomized data addressing the role of adjuvant systemic therapy in early-stage patients with endometrial adenocarcinoma.

10049 Background: It is unknown if the presentation, treatment, and outcomes differ between adults and pediatric patients with neuroblastoma. Methods: Medical records of 118 adults (patients >17 years old) and 112 pediatric patients (ages 2-17), who were treated for neuroblastoma at the University of Texas M.D. Anderson Cancer Center from 1994 to September 2012, were reviewed. International Neuroblastoma Risk Group (INRG) variables were abstracted. These include age, stage, tumor histology, and molecular and cytogenetic characteristics. The primary outcome of interest was overall survival (OS). Results: Median age of pediatric patients was 5 years (range 3-16) and 47 years (range 18-82) for adult patients. Beyond age and stage, other components of the INRG classification were not available for any adult patient. Cytogenetic and molecular studies were performed in 32 (26%) of pediatric patients. Adults with L1 disease experienced an actuarial OS of 94%, 90%, and 69% at years 3, 5, and 10, respectively. The cohort who presented with L2 disease had an estimated OS of 83% at 3 year, 73% at 5 years, and 41% at 10 years. Adults with M disease experienced an actuarial OS of 68%, 33%, and 13% at years 1, 2 and 5, respectively. In the adult cohort, the INRG stage was prognostic in univariate analysis (p<0.001). For all stage-matched risk categories, adults did not have a statistically different prognosis than children (L1-p=0.40, L2-p=0.54, M-p=0.73). Conclusions: Adult and pediatric patients with neuroblastoma achieve similar survival outcomes, with good prognosis for early-stage patients. Future work should focus on developing predictive markers for determining which patients benefit from more aggressive therapy. [Table: see text]

167 Background: The addition of H to chemotherapy has improved outcomes in HER2-positive early BC. This approach is associated with (w/) an increased risk (<4%) of congestive heart failure (CHF). Dose-dense (every 2 weeks) anthracycline-taxane therapy (Rx) improves survival compared to the every 3 week schedule and can be combined w/ anti-HER2 Rx w/ no increased risk of cardiotoxicity up to 36 months. Here we report the incidence of NYHA Class III/IV CHF in 2 phase II studies with longer follow-up. Methods: We conducted a retrospective review of pts w/ HER2 + early stage BC treated at MSKCC and DFCI on two trials: In trial A - pts received dd AC (60/600 mg/m2) x 4 → T (175mg/m2) x 4 (w/ pegfilgrastim) w/ H x 1 year. Trial B differed w/ use of weekly T (80mg/m2) x 12 and the addition of L (1000mg orally daily) x 1 year. Left ventricular ejection fraction (LVEF) was prospectively assessed by a multi-gated acquisition scan serially throughout Rx. Results: Trial A enrolled 70 pts and Trial B enrolled 95 pts w/ the median age of 46 years (range 27-73 years). Overall, the 5-year distant disease-free survival (DDFS) for trials A and B is 92% (95%Cl; 83-97%) and 89% (95%CI; 81-94%), respectively. The baseline median LVEF was 68% (range 52-81%). In total, 28 of 165 (17%) pts had pre-existing hypertension. Now at a median follow-up of 84 and 57 months respectively, only one (1.4%, 95%CI; 1.36-7.7%) and 4 (4.2%, 95%CI; 4.2-10.4%) pts developed CHF. Since our earlier report, 1 additional CHF event occurred (Trial B) at month 44. Conclusions: Longer follow-up of these 2 studies demonstrate that dd AC → TH with or without L is associated w/ a low risk of CHF. This is consistent w/ the long-term cardiac toxicity reported from the randomized phase III studies of H w/ conventionally scheduled anthracycline-based regimens (with or without taxanes). DDFS outcomes are also encouraging. Clinical trial information: NCT00591851 and NCT00482391.

355 Background: NAC and RC-PLND improves survival in MIBC and GC is a standard NAC option. However, little is known about GC efficacy endpoints and the individual contribution of NAC and surgery. Methods: Pts with clinical T2-T4aN0M0 MIBC treated from 1/2000 to 10/2012 with a planned 4 cycles of GC plus RC-PLND within 90 days (D) of NAC were evaluated retrospectively for the number (#) of cycles, dose delivered, D from end of NAC to RC-PLND, margin status, LN status and # of LN identified. Post-NAC pathologic endpoints included complete response (pT0), residual Non-MIBC disease (pTa/Tis/T1;N0) and ≥MIBC disease (≥pT2N0). Associations with overall survival (OS) and disease-free survival were analyzed using Cox regression; non-linear associations with # of resected LN used linear and quadratic terms. Results: 154 pts met inclusion criteria. 5-year (yr) OS was 61% (95% CI 53-71%). Post-NAC pT0 was achieved in 21% (32/154) and Non-MIBC in 25% (39/154 - pTa (2), pTis (25), pT1 (12)). Post-NAC pT0 and Non-MIBC had similar 5-yr OS (85% and 89%, respectively) and combined (<pT2) pts differed significantly from pts with ≥pT2, (87% (95% CI 78, 98%) and 38% (95% CI 27, 53%), respectively; p<0.001). Median D from NAC to RC-PLND was 34 and median # of resected LN was 19. On univariate analysis, # of cycles (4 vs <4), GC dose intensity and total dose, clinical stage (cT2 vs cT3/cT4), # of resected LN, positive (+) LN and + margins were significant for OS. In multivariate analysis, post-NAC pathology ≥pT2 (HR 6.7; 95% CI 2.6-17.4; p<0.001), + LN (HR 3.21; 95% CI 1.6-6.4; p=0.001) and + margins (HR 3.2; 95% CI 1.4-7.5; p=0.007) were significant for increased risk of death. Using a model with these 3 predictors to estimate the benefit of PLND, the hazard ratio decreased with each LN resected until 25 and then plateaued beyond 25 (p=0.016). Conclusions: NAC with GC has excellent drug delivery, permits rapid RC-PLND and achieves meaningful pathologic responses. Survival is similar with <pT2N0 and pT0N0 post NAC pathology. Pts with post NAC ≥pT2, + margins, and + LN do poorly. Increasing LN yield on PLND contributes to OS.

521 Background: Prognosis for high grade, non-metastatic upper tract urothelial carcinoma (UTUC) (renal pelvis or ureter) has not improved in past two decades. Given improvements in disease-free survival in phase III POUT study, adjuvant chemotherapy (AC) has been the preferred approach. Neoadjuvant chemotherapy (NAC) is favored based on median survival (OS) benefit seen in urothelial bladder cancer. We studied National Cancer Database (NCDB) to answer this question. Methods: We identified adults > 18 years with non-metastatic, high grade, UTUC. All patients received surgery of the primary site and chemotherapy in the neoadjuvant or adjuvant setting. Patient’s receiving radiation therapy or who died within 90 days of surgery were not included. Descriptive statistics, log-rank tests and cox-regression tests were performed. Patients achieving complete pathological response (pCR) defined as (pTis, pT0, pTa and N0) were assessed for OS. Results: 1191 patients with complete data were identified; 225 (19%) received NAC and 966 (81%) received AC. 60% were males, median age was 68 and 73% had Charlson score (CS) of ‘0’. Median follow-up time for alive patients was 30.4 and 36.7 months in the NAC and AC groups respectively. Renal pelvis was the primary in 760 cases (63%) and ureter in 441 (37%). On univariate analysis receiving NAC, age < 75 years and CS score ‘0’ was associated with significant survival benefit (p < 0.05). Similarly on multivariate analysis receiving NAC and having CS of ‘0’ had significantly better survival with HR 0.75 (CI 0.58-0.96) and 0.8 (CI 0.65-0.96) respectively. Age > 75 years had worse survival HR 1.34 (CI 1.08-1.66). Thirty-seven patients (17%) in the NAC group achieved pCR with OS > 71.6 months which was significantly better than AC group and non-responders in the NAC group (p < 0.05). There was a trend towards more benefit with NAC compared to AC in Stage 1 and 2 UTUC than in Stage 3 and 4. Conclusions: Our study indicates that subset of early stage UTUC benefit more from NAC comparing to AC. However, randomized prospective study is warranted to further explore the role of NAC in UTUC.
