RESUMO
To have a better understanding of our patients' knowledge of advance directive planning and execution, as well as communication with their oncologists regarding their wishes, we conducted a survey on our inpatient hematology-oncology services. A total of 68 unique hospitalized patients with a diagnosis of cancer completed surveys. Surveys were given to all oncology patients regardless of their reason for admission. Overall, 29% of the patients reported having had a discussion with their oncologist regarding their wishes if they became seriously ill or near death. Of those who did have this conversation, the majority said that they, rather than their physician, initiated it. Although the vast majority of patients (97%) knew what a living will was, only 54% had one in place. Twenty patients had a discussion with their oncologist, and 14 of them (70%) had a living will. This percentage was higher than in the group that did not have a conversation with their physician (48%; 23 of 48 patients), but the difference was not statistically significant. Most cancer patients admitted to an inpatient oncology unit either did not have or did not recall having a discussion with their oncologist regarding end-of-life issues. This study gives us a baseline of information in evaluating future interventions directed to improve the quality of patient-physician communication regarding end-of-life planning.
RESUMO
Transfusion of platelets is commonly indicated in the inpatient oncology setting. These platelets are obtained either through apheresis from a single donor or pooled from the whole blood of several donors. The amount of transfused platelets, infection risk, incidence of alloimmunization, and increases in posttransfusion platelet count are similar for these two platelet products. Although single-donor platelets are preferred over pooled platelets in some instances, single-donor platelets are often given regularly, despite a higher cost and more limited donor supply. Oncology fellows at Baylor University Medical Center at Dallas initiated an education campaign regarding the indications for pooled and single-donor platelet transfusions. The quality improvement campaign included seminars led by oncology fellows for nursing personnel and resident housestaff on the two oncology floors, as well as electronic correspondence to attending physicians. The number of pooled and single-donor platelet transfusions on the two floors was recorded for the 3 months after the education campaign (July-September 2011) and compared with the corresponding data from the previous year. Over the 3-month study period after the education campaign, the average percentage of pooled platelets transfused increased to 34.1% from 13.1% for the prior year. Given this increase, the estimated cost benefit over the 3-month study period was $45,000.
RESUMO
Estrogen and its metabolites play a significant role in the proliferation of hormone receptor-positive breast cancer. In postmenopausal women, aromatase inhibitors can significantly reduce estrogen levels by blocking enzyme-mediated estrogen synthesis within tissues. Third-generation aromatase inhibitors have now surpassed tamoxifen as first-line therapy for postmenopausal women with metastatic, hormone receptor-positive, breast cancer, showing improved response rates and time to progression. Aromatase inhibitors have shown incremental improvements in disease-free survival, lower local recurrence rates, lower metastatic recurrence rates, and a lower incidence of contralateral breast cancer over tamoxifen when used in the adjuvant setting. Aromatase inhibitors are recommended to be used as adjuvant therapy within the first 5 years of hormonal therapy and may be used either upfront for 5 years or sequenced with tamoxifen. No superiority of one aromatase inhibitor over another has yet been shown. The side effect profiles of aromatase inhibitors have some key differences compared with tamoxifen. These differences may influence treatment choices as well as impact compliance.
