e11624 Background: The molecular classification (Perou) helped to identify new groups of patients with different biological behaviors. A retrospective, descriptive, comparative trial with adjuvant chemotherapy treatment was conducted. Objectives: Analyze the natural history of the subgroups of patients, frequency, site of relapse and Disease-free survival (DFS). Materials and Methods: 200 Medical charts of patients with breast cancer were analyzed from 1997 to 2007, who had received adjuvant treatment without Trastuzumab. The 92, 5 % of Luminal A, 91 % of Luminal B y C, the 75.9 % of Her2 (+) and the 69.2 % of Triple Negative (TN) had received adjuvant therapy with FAC, while 30% of the last two groups were treated with taxanes and anthracyclines. We evaluated the site of the first relapse after adjuvant treatment in relation to the new molecular classification. Log-rank test was used to compare the rates of Disease-free survival (DFS). Results: Frequency: Luminal A (86, 42%) Luminal B y C (65, 33%) Her2 + (33, 17%) TN: (16, 8%) The locoregional relapse in the TN group was 36.4% (P = 0.003), the average of bone relapses were 64.5% on the four groups without statically significance compared to other groups. The CNS had a greater trend in TN groups (16.7%) and Her2+ (13.6%), compared to Luminal Type A-B (0 % y 8.3 %). Disease-free survival (DFS): Luminal A 65.0 ± 5.0 months Luminal B y C 50.3 ± 4.3 months HER2 42.9 ± 5.5 months TN 31.1 ± 7.3 months In the analysis of type A luminal subgroup, a prolonged disease free time was showed when compared with the others subgroups, of major statistical significance Log rank (p = 0.002). Conclusions: Her2 negative and TN tumors have less DFS and a higher locoregional and CNS relapse. No significant financial relationships to disclose.

e11614 Background: Triple negative (TN) breast cancer has a bad prognosis. It is associated with a poor progression-free and overall survivals. Accordingly, we explored the outcome of different molecular subtypes among a series of Egyptian breast cancer patients. Methods: A total of 661 non-metastatic breast cancer patients' files with were reviewed from Kasr Al-Aini Center of Clinical Oncology and Nuclear Medicine of Cairo University between January 2005 and December 2010. Data were analyzed for age; menopausal status, tumour size, nodal status, pathological type, grade; estrogen status, progesterone status, and human epidermal growth factor receptor 2 (HER2) status. Disease free survival (DFS) was the primary end point. Results: The median age was 50 years. 50.4% of patients were premenopausal, 93.1% had invasive duct carcinoma, 93.3% had grade II tumours, 79.4% had early tumours (T1&T2), 70.4% had positive lymph nodes, 51.7% had luminal A subtype, 21.3% had luminal B, 10.2% had HER2-enriched and 16.6% had TN. Disease free survival after 3 years for each subtype was 87.8% for luminal A, 86% for luminal B, 69% for TN and 66% for HER2 (p= .008). The 3-year disease-free survival was significantly better for postmenopausal patients 92.1% as compared with premenopausal patients 80.1% (P= <0.001), with early tumours (T1&T2) 92.1% & 87.3% respectively as compared with advanced tumours (T3+T4) 80.1% (p= <0.001), LN negative (N0) 98.1% as compared with LN positive (N1+N2) 85.2% and (N3) 68% (p= <0.001), (ER) positive 90.2% as compared with (ER) negative 78.2% (p= <0.001), (PR) positive 90% as compared with (PR) negative 80.2% (p= 0.003), non TNBC 89.8% as compared with TN 72.1% (p= 0.012). The 3-year disease-free survival for TN patients who received adjuvant platinum-based chemotherapy was 46% and for those who received adjuvant non-platinum chemotherapy was 78% (p= 0.135). Conclusions: In our series of Egyptian patients luminal breast cancer subtypes (A and B) had the highest 3-year disease-free survival followed by TN then HER2-enriched type. Adjuvant platinum based chemotherapy had no impact on the 3-year disease-free survival when compared with non-platinum chemotherapy in TN patients.

Aims and background Based on estrogen receptor (ER), progesterone receptor (PgR) and Her2/neu (HER2) expression, four breast cancer subtypes have been distinguished: luminal A (ER and/or PgR/HER2–, Ki67 <14%), luminal B (ER and/or PgR/HER2–, Ki67 ≥14% or ER and/or PgR/HER2), triple-negative (ER-/PgR-/HER2–), and HER2 (ER-/PgR-/HER2). Our aim was to evaluate the prognosis of these phenotypes in the pre-trastuzumab era in a large cohort of Italian women. Methods and study design We studied 2347 breast cancer patients, in stage I-II, registered by the Modena Cancer Registry from 1999 to 2006 in the Modena province, Italy. Overall survival, disease-free survival and second non-mammary tumors were evaluated. Results A total of 1868 luminal A (79.6%), 195 luminal B (8.3%), 205 triple-negative (8.7%) and 79 HER2 (3.4%) patients were identified. A better prognosis was observed for luminal A than for luminal B, HER2 and triple-negative subtypes (5-year overall survival, 91% vs 89% vs 87% vs 86%, respectively, P <0.001). Disease-free survival for pT1a and pT1b tumors was worse in HER2 (82%) than in triple-negative (90%), luminal B (95%) and luminal A (97%) (P = 0.013). Finally, luminal B patients had a significantly higher rate of second non-mammary tumors than the other groups. Conclusions In the pre-trastuzumab era, luminal A patients showed a better 5-year overall survival than luminal B, HER2 and triple-negative patients, but in terms of disease-free survival, HER2 subtype represented an unfavorable group over time, whereas the triple-negative group had an increased risk of relapse in the first 42 months and then decreased. Among each prognostic factor, ER <10%, Ki67 >14% and HER2 overexpression are considered as risk factors, but only HER2 positivity seems to preserve the role over time.

Aim: Adding pertuzumab to standard trastuzumab-based adjuvant therapy significantly improved invasive disease-free survival (IDFS) in the APHINITY trial. However, the magnitude of benefit was marginal in the overall population. Methods: We used GRADE (Grading of Recommendations Assessment, Development and Evaluation) analysis on data from APHINITY to build summary-of-findings tables to evaluate the efficacy, safety and quality of evidence of predefined clinical outcomes for the addition of pertuzumab to trastuzumab-based adjuvant therapy in patients with high-risk HER2-positive early breast cancer. Results: Pertuzumab significantly improved 3-year, event-free, absolute benefit in disease-free survival, IDFS and distant relapse-free interval (DFRI) in patients with node-positive or hormone receptor-negative disease. The analysis provides strength of evidence supporting the addition of pertuzumab in this patient population.

Background: The role of chemotherapy for isolated locoregional recurrence (iLRR) of breast cancer has not been firmly established after local therapies.Methods: We performed a multicenter, retrospective analysis to evaluate the clinical implications of chemotherapy in breast cancer patients with HER2-negative iLRR.Results: Of a total of 277 patients, 146 (52.7%) received chemotherapy for iLRR. Median follow-up duration was 56.1 months. Eighty-six (31.0%) patients had luminal B-like and 100 (36.1%) had TNBC iLRR. There was a trend of longer disease free survival (DFS) in the chemotherapy group (4-year DFS: 70.4 vs. 59.5%, HR = 0.68, 95% CI 0.45–1.02, log-rank p = 0.059). When adjusted with clinically relevant factors, DFS was significantly prolonged with chemotherapy (adjusted HR = 0.61, 95% CI 0.40–0.94, p = 0.023). Subgroup analyses for DFS showed patients with disease free interval (DFI) &lt;5 years or prior chemotherapy had a benefit from chemotherapy (adjusted HR = 0.57, p = 0.018; adjusted HR = 0.51, p = 0.005, respectively). Regarding the molecular subtypes, a longer DFS with chemotherapy was observed both in luminal B-like (4-year DFS: 77.8 vs. 55.0%, HR = 0.51, 95% CI 0.27–0.99, log-rank p = 0.048) and in TNBC patients (4-year DFS: 61.9 vs. 42.8%, HR = 0.49, 95% CI 0.24–1.02, log-rank p = 0.056), but not in luminal A-like.Conclusions: The chemotherapy for iLRR of breast cancer should be individualized for each patient, considering DFI, prior chemotherapy, and molecular subtypes.

Introduction In patients suffering from breast cancer, adjuvant radiation, chemotherapy, or immunotherapy, which immediately follow the surgery as the first line therapy, greatly improve overall (OS) and disease-free survival (DFS). Various regimens of adjuvant therapy for these patients have been tested contingent upon the clinical staging. Inclusion of adjuvant immunotherapy is particularly promising. Specific aim The aim of this study was to assess efficacy of trastuzumab (Herceptin) - comprising adjuvant immunotherapy in terms of overall and disease-free survival as compared to other adjuvant therapies. Patients All patients were presented with the Patient Bill of Rights and have provided the Patient Informed Consent to participate in this study. Eligible patients include those with primary tumors initially staged at the clinical stages: I-T1c N0, II-T0-2, N0-1, or IIIA-T3 N1, or patients for whom neoadjuvant chemotherapy provides the possibility to remove surgically a tumor at the stage IIIA T0-3 N2. Of 9,058 patients enrolled in the Breast Cancer Treatment Program between 2008 and 2015, 6,832 fulfilled the inclusion criteria. Statistical Analysis The effects of clinical and demographic factors on overall survival (OS) and disease-free survival (DFS) were assessed using Cox’s proportional hazards regression models. OS and DFS were evaluated with Kaplan-Meier calculations. The study was meeting the criteria for a controlled, open-access clinical trial. Results OS rates for years 1-7 were, respectively, 99.42%, 97.26%, 94.57%, 92.41%, 90.48%, 88.63%, and 88.23%; thus with the 5-year survival at 90.48%. The corresponding data for DFS were 96.17%, 84.07%, 77.26%, 72.57%, 68.59%, 65.04%, and 63.05%, respectively; thus with the 5-year DFS at 68.59%. Adverse effects, with the exception of cardiac complications, occurred in 1194 (17%), while causing withdrawal of 421 (6%) patients. Most of other adverse events were related to hepatotoxicity 1755 (25%) and fatigue 681 (9.7%). Conclusion These results demonstrate the great benefits of inclusion of immunotherapy as the adjuvant component as currently the best overall therapeutic strategy for the patients suffering breast cancers. As this strategy greatly exceeds any other therapeutic options available for practicing oncologists at the present time, it definitely justifies allocation of all needed public resources, while assuring highest quality health service for the patients in Poland.

452 Background: Surgical resection is the only curative treatment for patients with gallbladder cancer, despite surgical advances many patients ultimately develop recurrent disease. Management of resected gallbladder cancer mostly relies on single-arm trials and retrospective observations. The purpose of our study is to assess the role of adjuvant therapy in stage I-III gallbladder cancer patients who have undergone surgical resection. Methods: Clinical data were collected on 251 patients who underwent surgical resection for stage I-III gallbladder cancer and presented to Mayo clinic from January 2000-December 2015. Patients were then classified into adjuvant treatment group and surveillance only group. Overall survival and recurrence were compared between the two groups. Results: 78 (31.1%) patients received adjuvant therapy while 173 patients were observed only. Patients who received adjuvant tended to be younger (63.0[SD 11] vs 66.2 [SD 13.1]), have higher stage, and underwent extended surgery. Most patients received chemoradiotherapy (55) with 5-Fluorouracil (67.3%) and capecitabine (25.5%) as radiosensitizing agents. 21 patients received additional adjuvant chemotherapy. 27% of patients received chemotherapy as the sole adjuvant treatment. The most common chemo regimens included gemcitabine (52.3%) and gemcitabine plus cisplatin combination (23.8%). On multivariate analysis patients > 65 years(HR 1.53 [1.07-2.19], p = 0.02), males (HR 1.7 [1.2-2.4], p = 0.003), positive margins (2.77 [1.69-4.38], p < 0.01), and stage III (HR 1.91 [1.35-2.70], p < 0.01) had worse overall survival. Patients who underwent extended radical resection (HR 0.73 [0.51-1.05], p = 0.09) had better overall survival. Adjuvant therapy had no statistical significant effect on overall survival (HR 1.10 [0.75-1.59], p = 0.63 or disease free survival (HR 1.05 [0.69-1.59], p = 0.81) on overall population. However, in stage IIIB, patients receiving adjuvant therapy had better overall survival (HR 0.51 [0.25-1.01], p = 0.05) and disease free survival (HR 0.45 [0.19-1.09], p = 0.06). Conclusions: In our study, adjuvant treatment, especially chemoradiation therapy, was only beneficial in patients with stage IIIb gallbladder cancer patients.
