Giant left myxoma with mitral valve obstruction.

We present a case of a patient admitted with acute pulmonary edema. An echocardiogram showed a giant myxoma of the left atrium causing mitral valve obstruction. The patient underwent urgent cardiac surgery for tumor resection. There were no postoperative complications, and the follow-up was uneventful.

Effectiveness of Adjuvant Ovarian Function Suppression in Premenopausal Women With Early Breast Cancer: A Multicenter Cohort Study.

BACKGROUND: Ovarian function suppression (OFS) with tamoxifen or aromatase inhibitors (AIs) improves disease-free survival in premenopausal women with breast cancer, mostly in those at higher risk of recurrence. However, its real-world use and impact remain poorly understood. PATIENTS AND METHODS: This is a multicenter retrospective cohort study of premenopausal women with stage I to III hormone receptor-positive breast cancer diagnosed from 2006 to 2015 that aimed to look at the uptake and effectiveness of the addition of OFS to backbone endocrine therapy (tamoxifen or AI). To deal with confounding, we used both multivariate modeling and propensity score matching. RESULTS: Of 1717 eligible patients, 17.1% were treated with OFS. There was a substantial increase of use of OFS over time, especially from 2014 onward (16% vs. 25% after 2014), particularly for the combination with AI (0.4% vs. 8% after 2014). In a multivariate model, only younger age and year of diagnosis ≥ 2014 were associated with OFS utilization (both P < .001). With a median follow-up of 38 months (P25-P75, 19.6-66.4 months), patients receiving OFS had a better overall survival than those not receiving OFS (adjusted hazard ratio, 0.44; 95% confidence interval, 0.19-0.96; absolute benefit at 5 years, 2.1% [95.3% vs. 93.2% in those not receiving OFS]). A similar benefit was identified using propensity score matching. CONCLUSIONS: In the real-world setting, there was an increase in the use of OFS after 2014. After 2014, one-quarter of premenopausal women received adjuvant OFS, of which more than 30% received it in combination with an AI. In this study, the use of adjuvant OFS was associated with an overall survival benefit.

Treatment adoption and relative effectiveness of aromatase inhibitors compared to tamoxifen in early breast cancer: A multi-institutional observational study.

BACKGROUND: Since 2005, aromatase inhibitors (AIs) have been the adjuvant treatment of choice for postmenopausal women with early breast cancer (BC). In this study we characterize the adoption of AIs in Portugal, variables associated with treatment administration, and compare its effectiveness (either in monotherapy or sequential therapy) to tamoxifen monotherapy (TAM). PATIENTS AND METHODS: This was a retrospective cohort study that included postmenopausal women with stage I-III hormone receptor (HR) positive BC diagnosed from 2006 to 2008 and treated with adjuvant endocrine therapy in four participating institutions. RESULTS: Of the 1283 eligible patients, 527 (41%) received an AI (16% as monotherapy, 25% as sequential therapy) and 756 (59%) TAM. Patients treated with AI had less differentiated tumors, with higher TNM stage, and were more frequently HER2-positive. Use of AI also differed by center (use range from 33% to 75%, p < 0.001). With a median follow-up of 6.3 years and controlling for clinicopathological and treatment characteristics, treatment with AI had a better overall survival (OS) when compared with TAM (adjusted-HR 0.55, 95% CI 0.37-0.81). CONCLUSION: AIs were successfully introduced as adjuvant treatment for HR-positive BC in Portuguese hospitals. Its use was influenced by tumor and patient characteristics, but also center of care. In this large cohort, AI use was associated with an OS benefit.

Variation in type of adjuvant chemotherapy received among patients with stage I breast cancer: A multi-institutional Portuguese cohort study.

BACKGROUND: A contemporary US study showed an increase in the use of chemotherapy in the last decade for some patients with stage-I breast cancer; with a rise in more intensive regimens, and declining use of anthracyclines. Nevertheless, there is still uncertainty on the absolute benefit of chemotherapy for these patients and the optimal regimen. In this study we compare those findings with the patterns of care among a Portuguese cohort of stage-I breast cancers. METHODS: Retrospective cohort study of patients with stage-I breast cancer diagnosed from 2006 to 2008 at four Portuguese institutions. The use and type of chemotherapy was evaluated. RESULTS: Among patients with stage I-III breast cancer 39.4% (n = 682) had stage I disease. Of the 595 eligible patients, 22.4% were treated with chemotherapy, 33.9% aged <55 years vs. 12.7% aged >65 years (p < 0.001). Thirteen percent of patients with hormone receptor (HR)+/HER2- tumors, 52.7% of patients with HER2+ and 66.0% of patients with HR-/HER2- received chemotherapy (p < 0.001). In addition, we found inter-institutional variability, with the use of chemotherapy ranging from 0.0% to 43.4% (p < 0.001). Eighty-five percent of patients treated with chemotherapy received less-intensive regimens with anthracycline-based regimens, such as doxorubicin and cyclophosphamide, being the most frequently used, while docetaxel and cyclophosphamide was only used in 1.5% of cases. CONCLUSIONS: Overall, almost one-quarter of patients received chemotherapy with institutional variability. When treated, mostly less-intensive associations including anthracyclines were used, which contrasts with contemporary US practice. This study highlights the need for health-services research to understand local practices and tailor quality improvement interventions.

The state of the art of cancer control in 30 European countries in 2008.

Inequalities in cancer incidence, mortality and survival represent a major challenge for public health. Addressing this challenge requires complex and multidisciplinary approaches. Sharing successful experiences from across Europe may therefore be of benefit. We describe the state of the art of cancer control structures in the 27 European Union countries, plus Iceland, Norway and Switzerland, at the beginning of 2008. Information on cancer plans, cancer registries, cancer screening, Human Papillomavirus (HPV) vaccination and smoking restrictions in each country was identified through PubMed, the official websites of national and international organizations and Google searches. Experts and/or health authorities from each country completed and validated the information. Sixteen countries had implemented national cancer plans in 2008. Twenty four countries had population-based cancer registries with 100% coverage. The exceptions were Greece and Luxembourg (no population-based registry yet), France, Italy and Spain (<50%), and Switzerland (62%). In 9 countries, population coverage of breast cancer screening was 100% with participation ranging from 26 to 87%; 8 countries did not have organized programmes. Seven countries had cervical cancer screening programmes with 100% coverage with participation ranging from 10 to 80%; 8 countries had no organized programme. Nine countries had announced national HPV vaccination policies by early 2008. Six countries had organized colorectal cancer screening programmes. Five countries had complete bans on smoking in public places. There is wide international heterogeneity in cancer control structures in Europe. This provides considerable scope and motivation for cooperation and sharing of experience.

Improving cancer control in the European Union: conclusions from the Lisbon round-table under the Portuguese EU Presidency, 2007.

Cancer is a major cause of morbidity and mortality in the European Union (EU), and a public health burden. Improving cancer control in the EU will require implementation of efficient strategies within Member States and better policy coordination between them. In cooperation between the rotating EU Presidencies of Germany (2007), Portugal (2007) and Slovenia (2008), special attention was devoted to an integrated approach to cancer control in EU policies and programmes. A round-table focussed on national cancer plans, population-based cancer registries and cancer screening programmes was held during the Health Strategies in Europe meeting in Lisbon in July 2007, under the Portuguese Presidency. These three topics were selected as critical for improving cancer control at both national and European levels. The round-table was designed to produce a set of recommendations to inform EU cancer policy. This paper provides a résumé of the conclusions and recommendations, to stimulate wider discussion and policy development. The conclusions of the meeting were presented at the Employment, Social Policy, Health and Consumer Affairs Council in December 2007 and cancer was included in the Council Conclusions for the new European Health Strategy. Success in cancer control will require consistent attention from future EU Presidencies, such as the initiative of the Slovenian EU Presidency in early 2008.
