SummaryBackgroundFor women with oestrogen receptor (ER)-positive early breast cancer, treatment with tamoxifen for 5 years substantially reduces the breast cancer mortality rate throughout the first 15 years after diagnosis. We aimed to assess the further effects of continuing tamoxifen to 10 years instead of stopping at 5 years.MethodsIn the worldwide Adjuvant Tamoxifen: Longer Against Shorter (ATLAS) trial, 12 894 women with early breast cancer who had completed 5 years of treatment with tamoxifen were randomly allocated to continue tamoxifen to 10 years or stop at 5 years (open control). Allocation (1:1) was by central computer, using minimisation. After entry (between 1996 and 2005), yearly follow-up forms recorded any recurrence, second cancer, hospital admission, or death. We report effects on breast cancer outcomes among the 6846 women with ER-positive disease, and side-effects among all women (with positive, negative, or unknown ER status). Long-term follow-up still continues. This study is registered, number ISRCTN19652633.FindingsAmong women with ER-positive disease, allocation to continue tamoxifen reduced the risk of breast cancer recurrence (617 recurrences in 3428 women allocated to continue vs 711 in 3418 controls, p=0·002), reduced breast cancer mortality (331 deaths vs 397 deaths, p=0·01), and reduced overall mortality (639 deaths vs 722 deaths, p=0·01). The reductions in adverse breast cancer outcomes appeared to be less extreme before than after year 10 (recurrence rate ratio [RR] 0·90 [95% CI 0·79–1·02] during years 5–9 and 0·75 [0·62–0·90] in later years; breast cancer mortality RR 0·97 [0·79–1·18] during years 5–9 and 0·71 [0·58–0·88] in later years). The cumulative risk of recurrence during years 5–14 was 21·4% for women allocated to continue versus 25·1% for controls; breast cancer mortality during years 5–14 was 12·2% for women allocated to continue versus 15·0% for controls (absolute mortality reduction 2·8%). Treatment allocation seemed to have no effect on breast cancer outcome among 1248 women with ER-negative disease, and an intermediate effect among 4800 women with unknown ER status. Among all 12 894 women, mortality without recurrence from causes other than breast cancer was little affected (691 deaths without recurrence in 6454 women allocated to continue versus 679 deaths in 6440 controls; RR 0·99 [0·89–1·10]; p=0·84). For the incidence (hospitalisation or death) rates of specific diseases, RRs were as follows: pulmonary embolus 1·87 (95% CI 1·13–3·07, p=0·01 [including 0·2% mortality in both treatment groups]), stroke 1·06 (0·83–1·36), ischaemic heart disease 0·76 (0·60–0·95, p=0·02), and endometrial cancer 1·74 (1·30–2·34, p=0·0002). The cumulative risk of endometrial cancer during years 5–14 was 3·1% (mortality 0·4%) for women allocated to continue versus 1·6% (mortality 0·2%) for controls (absolute mortality increase 0·2%).InterpretationFor women with ER-positive disease, continuing tamoxifen to 10 years rather than stopping at 5 years produces a further reduction in recurren...

<b><i>Background:</i></b>There is a paucity of literature examining the impact of timing of surgery after neoadjuvant chemotherapy. <b><i>Objective:</i></b>This study aimed to analyze the impact of the time taken to initiate surgical treatment following completion of neoadjuvant chemotherapy on patients’ outcomes by evaluating their pathological response, overall survival (OS), and disease-free survival (DFS). <b><i>Methods:</i></b>This is a retrospective review of 611 patients diagnosed with stage II and III breast cancer that received neoadjuvant chemotherapy and surgery between January 2004 and December 2014. The data was collected from a prospectively gathered registry. The patients were stratified into three cohorts according to the time of surgery after neoadjuvant chemotherapy: &#x3c;4 weeks, 4–7 weeks, or ≥8 weeks. Outcomes were assessed using Kaplan-Meier curves, and the variables were compared using log-rank statistics. <b><i>Results:</i></b>The 5-year OS rate was 89.6% and the 5-year DFS rate was 74%. OS and DFS were not significantly different when stratified according to timing of surgery; however, the trends of OS and DFS were poor when surgery was delayed for ≥8 weeks. Median OS and median DFS have not yet been reached. Of the 17% of patients that had surgery after ≥8 weeks, 12.9% had pathological complete response (pCR), while among those that received surgery 4–7 weeks and &#x3c;4 weeks after neoadjuvant chemotherapy, 26% and 21% had pCR, respectively (<i>p</i> = 0.02). ER+/HER-2+ patients had a statistically significant decrease in pCR if surgery was performed after ≥8 weeks. <b><i>Conclusion:</i></b>Our patients showed improved pCR if surgery was performed within 8 weeks, especially for ER+/HER-2+ patients. All patients had better OS and DFS trends if surgery was performed between 4 and 7 weeks after neoadjuvant chemotherapy.

Background: In the low and middle income countries delays in seeking consultation, late presentation, and the availability of breast cancer management for all patients, represent major challenges. Materials and Methods: The delay in seeking medical advice and the pathological tumor size of females breast cancer patients in the years 2004–2006 in Port Said, Egypt were studied and compared with previous studies by Elzawawy published since 1987. We report the progress of availability of breast cancer management from 1984 until the end of June 2007. Results: There was a decline in advanced cases. Mean time from a symptom to seeking advice was 18, 8, 3, and 1 month respectively in 1987, 1989, 1999, and 2007. Since 1984, facilities for all lines of comprehensive management have been established, interconnected, and been made accessible for all citizens, free of charge. Conclusion: Breast cancer problems are characterized by a certain multi-complexity. There is no one single cause for late cases. However, we report that the availability of cancer management facilities could lead to earlier presentation. Early detection programs would be frustrating for both patients and health authorities if patients were unable to afford accessible treatment.

In the small group of patients who regained weight, a longer distance between the pylorus and the beginning of the staple line, as well as a higher RGV on GCTV 2 years after LSG, were both associated with increased weight regain. Gastric computed tomography volumetry with RGV measurement holds promise as a useful research tool after LSG.

386 Background: Everolimus and Lutetium-177 PRRT were approved as monotherapy. However, animal model research showed synergistic effect of the combination. The goal of this study is to assess the safety and efficacy of the combination in treatment of unresectable G1-2 NETs of all gastrointestinal, lung and pancreatic origins. Methods: This is a phase 1-2 study. Phase 1 part involves finding the maximum tolerating dose (MTD) of everolimus and accordingly to recommend dose for phase II part. Starting everolimus dose was 5 mg OD. Patients were treated concurrently with Lu-177 DOTATOC therapy at intervals of 8 weeks (+/-1 week) with average of 4 sessions. Sample size calculation was based on the expected response of the combination to be 30% with power of 80 and type 1 of .05, compared to the known response rate of everolimus alone of 5%. Primary end point is safety. Other end points include response rate, PFS and OS. Results: Eleven patients, with progressive disease, were enrolled. Characteristics are summarized in the table. Everolimus MTD was 10 mg once daily. However, dose was reduced to 5 mg OD in 3 patients and to 5 mg once every other day in 2 patients. Median number of sessions of Lu-177: 3 sessions, and median cumulative dose: 300 mci. Most common G1-2 toxicities: stomatitis (90.9%), Nausea (72.7%), Fatigue (63.6%), anorexia (36.4%), diarrhea (36.4%) and skin and nail changes (36.4%). G3 toxicities (36%) were infection, fatigue, pneumonitis and neutropenia. No grade 4 toxicities. Reasons of discontinuation were toxicity in 3 patients, progression in 3, stroke in 1 and due to interruption of therapy in 4 patients. ORR: 1 PD, 1 PR and 9 SD. At median FU of 18.9 months, 7 patients are still alive, 3 died, and 1 lost to FU. Median PFS: 23.3 months. Conclusions: Combination of Everolimus and the Lu-177 PRRT appear to be safe and effective. Four patients, due to strict compliance criteria in the study protocol, were removed from the study prematurely resulting in undertreatment. Larger and randomized studies are required to confirm such findings.[Table: see text]

<b><i>Background:</i></b> Cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors have been a significant breakthrough in the management of hormone receptor-positive, HER2-negative metastatic breast cancer based on the results of several large phase III randomized trials. The most common reported toxicity is myelosuppression due to disease such as leukopenia, neutropenia, and thrombocytopenia. Other toxicities associated with CDK 4/6 inhibitors include mucositis, fatigue, gastrointestinal side effects, hepatic toxicities, and QTc prolongation. Despite a good toxicity profile in pivotal studies, the increased rates of use in clinical practice may show less prevalent but lethal toxicity such as lung injury. <b><i>Case Presentation:</i></b> Here, we describe a female patient with metastatic hormone receptor-positive/human epidermal growth factor 2-negative breast cancer who developed lung toxicity while on ribociclib. <b><i>Discussion:</i></b> Lung injury is a possible side effect of CDK 4/6 inhibitors and there is an increasing need to understand the management of this side effect.

Purpose. This study was designed to examine the relationship between breast cancer molecular subtypes and pathological response to neoadjuvant chemotherapy (NAC) ± trastuzumab, in locally advanced breast cancer (LABC). Methods. Female patients with LABC (T2–T4, N0–N2, and M0) who received neoadjuvant chemotherapy + trastuzumab if HER2+ subtype, followed by surgery and radiotherapy ± hormonal therapy, were identified. The primary endpoint was pathologic complete response (pCR) in the breast and axilla (ypT0/ypN0), with final analysis on disease-free survival (DFS) and overall survival (OS). Results. Six hundred eighty-one patients with a median age of 44 years, premenopausal: 70%, median tumour size: 7.0 cm (range 4–11 cm), stage II B: 27% and III A/III B: 73%, ER+/HER2−: 40.8%, ER−/HER2−: 23%, ER+/HER2+: 17.7%, and ER−/HER2+: 18.5%. Overall pCR (ypT0/ypN0) was 23%. The pCR rates based on molecular subtypes were ER+/HER2−: 9%; ER+/HER2+: 29%; ER−/HER2−: 31%; and ER−/HER2+: 37%. At median follow-up of 61 months, ER+/HER2+ and ER+/HER2− subtypes had the best 5-year DFS and OS; meanwhile, ER−/HER2+ and ER−/HER2− subtypes had the worst. Conclusion. Women with ER+/HER2− disease are the least likely to achieve pCR, with the highest rates in HER2+ and triple-negative subgroups. Degree of response is associated with OS; despite the comparatively higher likelihood of achieving pCR in ER−/HER2+ and triple-negative, these subgroups experience a survival detriment. We are consistent with the published data that patients who attain the pathological complete response defined as ypT0/ypN0 have improved outcomes.
