RESUMO

BACKGROUND AND PURPOSE: The optimal treatment for adults with newly diagnosed medulloblastoma (MB) has not been defined. We report a large series of cases from the Rare Cancer Network. MATERIAL AND METHODS: Thirteen institutions enrolled 206 MB patients who underwent postoperative radiotherapy (RT) between 1976 and 2014. Log-rank univariate and Cox-modeled multivariate analyses were used to analyze data collected. RESULTS: Median patient age was 29 years; follow-up was 31 months. All patients had the tumor resected; surgery was complete in 140 (68%) patients. Postoperative RT was given in 202 (98%) patients, and 94% received craniospinal irradiation (CSI) and, usually, a posterior fossa boost. Ninety-eight (48%) patients had chemotherapy, mostly cisplatin and vincristine-based. The 10-year local control, overall survival, and disease-free survival rates were 46%, 51%, and 38%, respectively. In multivariate analyses, Karnofsky Performance Status (KPS) ≥80 and CSI were significant for disease-free and overall survival (P ≤ .04 for all); receiving chemotherapy and KPS ≥80 correlated with better local-control rates. CONCLUSIONS: Patients with high KPS who received CSI had better rates of disease-free and overall survival. Chemotherapy was associated with better local control. These results may serve as a benchmark for future studies designed to improve outcomes for adults with medulloblastoma.

RESUMO

BACKGROUND: Brain metastases significantly affect morbidity and mortality rates for patients with metastatic breast cancer. Treatment for brain metastases lengthens survival, and options such as stereotactic radiosurgery (SRS) can increase survival to 12 months or longer. This study retrospectively analyzes the prognostic factors for overall survival (OS) for patients with one or multiple brain metastases from breast cancer treated with SRS. METHODS: Between December 2001 and May 2015, 111 patients with brain metastases from breast cancer were grouped by potential prognostic factors including age at diagnosis, Karnofsky Performance Status (KPS) score, number of brain metastases, and whether or not they received adjuvant treatments such as whole brain radiotherapy (WBRT) or surgical resection. Survival rates were determined for all groups, and hazard ratios were calculated using univariate and multivariate analyses to compare differences in OS. RESULTS: Median OS was 16.8 ± 4.22 months. Univariate analysis of patients with a KPS ≤60 and multivariate analysis of KPS 70-80 showed significantly shorter survival than those with KPS 90-100 (5.9 ± 1.22 months, 21.3 ± 11.69 months, and 22.00 ± 12.56 months, P = 0.024 and < 0.001). Other results such as age ≥65 years and higher number of brain metastases trended toward shorter survival but were not statistically significant. No difference in survival was found for patients who had received WBRT in addition to SRS (P = 0.779). CONCLUSION: SRS has been shown to be safe and effective in treating brain metastases from breast cancer. We found our median survival to be 16.8 ± 4.22 months, an increase from other clinical reports. In addition, 38.4% of our population was alive at 2 years and 15.6% survived 5 years. Significant prognostic factors can help inform clinical treatment decisions. This study found that KPS was a significant prognostic indicator of OS in these patients.

RESUMO

Patients with brain metastasis from renal cell carcinoma (RCC) or melanoma have historically had very poor prognoses of less than one year. Stereotactic radiosurgery (SRS) can be an effective treatment for patients with these tumors. This study analyzes the effect of pretreatment prognostic factors on overall survival (OS) for RCC and melanoma patients with metastasis to the brain treated with SRS. A total of 122 patients with brain metastases from either RCC or melanoma were grouped by age at brain metastasis diagnosis, whether they received whole brain radiation therapy (WBRT) in addition to SRS, or they underwent surgical resection, Karnofsky Performance Score (KPS), number of brain metastases, and primary tumor. Median survival times for melanoma patients and RCC patients were 8.20 ± 3.06 and 12.70 ± 2.63 months, respectively. Patients with >5 metastases had a significantly shorter median survival time (6.60 ± 2.45 months) than the reference group (1 metastasis, 10.70 ± 13.40 months, p = 0.024). Patients with KPS ≤ 60 experienced significantly shorter survival than the reference group (KPS = 90-100), with median survival times of 5.80 ± 2.46 months (p < 0.001) and 45.20 ± 43.52 months, respectively. We found a median overall survival time of 12.7 and 8.2 months for RCC and melanoma, respectively. Our study determined that a higher number of brain metastases (>5) and lower KPS were statistically significant predictors of a lower OS prognosis.

RESUMO

BACKGROUND: The local-regional management of female breast cancer has been extensively investigated worldwide. The optimal approach for males diagnosed with breast cancer is less clear. We have analyzed the treatment of male breast cancer using a population-based national registry to determine the impact of surgery and radiation therapy on survival. MATERIALS AND METHODS: The Surveillance Epidemiology and End Results (SEER) database was queried to identify males with invasive ductal carcinoma of the breast who underwent primary surgical resection (radical mastectomy, modified radical mastectomy, total mastectomy, or segmental) for the years 1983 to 2002. Demographic, clinical, and pathologic data were culled and analyzed to determine the impact of radiation therapy (RT) following resection. Survival rates were estimated using the Kaplan-Meier method and significance was determined using the log-rank test (P<0.05). Multivariate analysis with the Cox proportional hazards model was performed to determine factors significant for overall (OS) and cause-specific survival (CSS). RESULTS: A total of 1337 patients met the eligibility criteria and were analyzed. Median follow-up was 7.3 years (range, 1 mo to 25 y). Most men underwent modified radical mastectomy (n=1062) with a minority undergoing segmental (n=113). About 329 men received postoperative external beam RT. The median rates of OS and CSS for all men were 10.5 years and not yet reached, respectively. The surgical procedure did not significantly associate with OS or CSS. By stage, RT was associated with improved OS for stage I (P=0.03). There was a trend for improved survival with stage II (P=0.21) and III (P=0.15). RT was not associated with improved CSS by stage. RT improved rates of OS and CSS in N2 patients without reaching statistical significance (P=0.10 and 0.22). On multivariate analysis, advancing age, stage and grade, and no postoperative RT predicted for worse OS. However, when controlled for those with known hormone receptor status (n=978), only the factors of advancing age, stage, grade, and hormone receptor negativity predicted for worse OS. Advancing age, stage, and grade were the only predictors of CSS irrespective of the cohort analyzed. CONCLUSIONS: The primary surgical procedure did not ultimately influence OS or CSS in this population-based registry of males with breast cancer. A statistically nonsignificant improvement with postoperative RT was observed in men with lymph node involvement, larger tumor size, or higher stage. When controlled for age, stage, and grade in multivariate analysis, postoperative RT predicted for improved OS but not CSS. These data suggest a beneficial effect of RT in the postoperative setting. A prospective study is necessary to further elucidate appropriate treatment strategies for men with breast cancer.

RESUMO

OBJECTIVES: To assess toxicity and efficacy of intensity-modulated radiation therapy (IMRT) for anal cancer. METHODS: Records of 152 patients were reviewed retrospectively from multiple institutions. Data on disease control and toxicity were collected as well as patient and treatment characteristics. Acute (<6 mo) and late (≥6 mo) severe toxicity (grade ≥3) were graded. Four patients were excluded due to the presence of metastatic disease or stage TX. Late toxicity data were available for 120 patients. RESULTS: Median cumulative IMRT dose was 51.25 Gy (median, 28 fractions). All but 2 patients received chemotherapy. With median follow-up of 26.8 months, local control at 3 years was 87%, worse for patients with T3-T4 than T1-T2 disease on univariate analysis (79% vs. 90%; P=0.04). Regional control, distant control, and overall survival were 97%, 91%, and 87%, respectively, at 3 years. Nodal status was associated with regional control, distant control, and overall survival (P<0.01 for each). Most common severe acute toxicity was hematologic (41%), skin (20%), and gastrointestinal tract (11%). Two grade 5 toxicities occurred (hematologic and gastrointestinal tract). Severe late toxicity affected skin (1%) and gastrointestinal tract (3%). CONCLUSIONS: IMRT with chemotherapy resulted in excellent local control. Although T stage predicted worse local control, most T3-T4 disease was controlled with IMRT. Nodal status predicted regional and distant control and overall survival. Severe toxicity was acceptable.

RESUMO

Patients with metastatic renal cell carcinoma (RCC) to the brain have a very poor prognosis of three months if left untreated. SRS is an effective treatment modality in numerous patients. This case exemplifies the utility of stereotactic radiosurgery (SRS) in prolonging survival and maintaining quality of life in a patient with RCC. This 64-year-old female patient initially presented to her primary care physician 22 months after a left nephrectomy for RCC with complaints of mild, intermittent headaches and difficulty with balance. An MRI revealed five cerebellar lesions suspicious for intracranial metastasis. The patient's first GKRS treatment targeted four lesions with 22 Gy at the 50% isodose line. She underwent a total of seven GKRS treatments over the next 60 months for recurrent metastases to the brain. 72 months and 12 months have now passed since her brain metastases were first discovered and since her last GKRS treatment, respectively, and this woman is alive with considerable quality of life and no evidence of metastatic reoccurrence. This case shows that repeated GKRS treatments, with minimal surgical intervention, can effectively treat multiple intracranial lesions in select patients, prolonging survival and avoiding iatrogenic neurocognitive decline while maintaining a high quality of life.

RESUMO

The management of brainstem metastases is challenging. Surgical treatment is usually not an option, and chemotherapy is of limited utility. Stereotactic radiosurgery has emerged as a promising palliative treatment modality in these cases. The goal of this study is to assess our single institution experience treating brainstem metastases with Gamma Knife radiosurgery (GKRS). This retrospective chart review studied 41 patients with brainstem metastases treated with GKRS. The most common primary tumors were lung, breast, renal cell carcinoma, and melanoma. Median age at initial treatment was 59 years. Nineteen (46%) of the patients received whole brain radiation therapy (WBRT) prior to or concurrent with GKRS treatment. Thirty (73%) of the patients had a single brainstem metastasis. The average GKRS dose was 17 Gy. Post-GKRS overall survival at six months was 42%, at 12 months was 22%, and at 24 months was 13%. Local tumor control was achieved in 91% of patients, and there was one patient who had a fatal brain hemorrhage after treatment. Karnofsky performance score (KPS) >80 and the absence of prior WBRT were predictors for improved survival on multivariate analysis (HR 0.60 (p = 0.02), and HR 0.28 (p = 0.02), respectively). GKRS was an effective treatment for brainstem metastases, with excellent local tumor control.

RESUMO

Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM (rGBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery (GKRS) salvage therapy. Following a PubMed search for studies using GKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rGBM treatment. In this review, we compare Overall survival following diagnosis, Overall survival following salvage treatment, Progression-free survival, Time to recurrence, Local tumor control, and adverse radiation effects. This report discusses results for rGBM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates (from diagnosis, range: 16.7-33.2 mo; from salvage, range: 9-17.9 mo). Three studies identified median progression-free survival (range: 4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects (range: 0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rGBM patient. However, there needs to be a randomized clinical trial to test GKRS for rGBM before the possibility of selection bias can be dismissed.

RESUMO

OBJECTIVES: To review outcomes for patients who received intraoperative radiotherapy (IORT) for upper-extremity sarcoma. METHODS: We identified patients with upper-extremity tumors who were treated with external beam radiotherapy, surgery, and IORT, with or without chemotherapy. Kaplan-Meier estimates for overall survival (OS), central control (CC), local control (LC), and distant control (DC) were obtained. RESULTS: Sixty-one patients were identified. Median age was 50 years (range, 13 to 95 y). Median follow-up was 5.9 years. Eleven patients had gross (R2; n=1) or microscopic (R1; n=10) disease at the time of IORT. IORT doses ranged from 7.50 to 20.00 Gy. External beam radiotherapy doses ranged from 19.80 to 54.00 Gy. OS at 5 and 10 years was 72% and 58%, respectively. LC at 5 and 10 years was 91% and 88%, respectively. DC at 5 and 10 years was 80% and 77%, respectively. Patients treated for recurrent disease had inferior 5-year OS compared with patients with first diagnoses (63% vs. 74%; P=0.02) and lower 5-year LC (67% vs. 94%; P<0.01). For patients with R1 or R2 resections, LC at 5 and 10 years was 100% and 86%, respectively; for patients with R0 resections, LC was 89% at both 5 and 10 years (P=0.98). Severe toxicity attributable to treatment was noted for 4 patients (7%). CONCLUSIONS: For upper-extremity sarcoma, treatment including IORT was associated with excellent LC, limb preservation, and survival. LC rates were excellent for patients with positive margins after resection. Patients with recurrent disease had worse outcomes, but limb preservation was achievable for most patients.

RESUMO

OBJECTIVE: To assess the survival and role of adjuvant chemotherapy in adult medulloblastoma. METHODS: We reviewed outcomes of 66 patients (aged 18 y or more; median age, 33 y) with medulloblastoma. Forty-four (67%) patients had M0 disease, 9 had M1-M4, and 13 had MX. Thirty-one patients each for whom risk stratification was available were classified as high risk or standard risk. Fifty-six patients had histologic results: classic histology was the most common (n=46 [84%]), followed by desmoplastic (n=9), and large cell/anaplastic (n=1). Overall survival (OS) and progression-free survival (PFS) were estimated with Kaplan-Meier curves and log-rank tests. Cox regression analysis was used to compare recurrences. RESULTS: Median follow-up was 6.7 years. The estimated 5-year OS and PFS were 74% and 59%, respectively. High-risk versus standard-risk classification was associated with worse OS (61% vs. 86%; P=0.03) and recurrence (hazard ratio, 2.56; P=0.05) and a trend for worse PFS (49% vs. 69%; P=0.13). Gross total resection was associated with improved OS (P=0.03) and a trend toward improved PFS (P=0.09). No chemotherapy benefit could be demonstrated for the group as a whole. For high-risk patients with classic histology (n=25), chemotherapy was associated with a trend for improvement in 5-year PFS from 36% to 71% (P=0.10) and in 5-year OS from 49% to 100% (P=0.08). CONCLUSIONS: In adult patients with medulloblastoma, the extent of resection and risk classification predicts the outcome. These results suggest a chemotherapy benefit for high-risk patients with classic histology.

RESUMO

Objective and Importance. Brainstem metastases (BSMs) are uncommon but serious complications of some cancers. They cause significant neurological deficit, and options for treatment are limited. Stereotactic radiosurgery (SRS) has been shown to be a safe and effective treatment for BSMs that prolongs survival and can preserve or in some cases improve neurological function. This case illustrates the use of repeated SRS, specifically Gamma Knife radiosurgery (GKRS) for management of a unique brainstem metastasis. Clinical Presentation. This patient presented 5 years after the removal of a lentigo maligna melanoma from her left cheek with left sided facial numbness and paresthesias with no reported facial weakness. Initial MRI revealed a mass on the left trigeminal nerve that appeared to be a trigeminal schwannoma. Intervention. After only limited response to the first GKRS treatment, a biopsy of the tumor revealed it to be metastatic melanoma, not schwannoma. Over the next two years, the patient would receive 3 more GKRS treatments. These procedures were effective in controlling growth in the treated areas, and the patient has maintained a good quality of life. Conclusion. GKRS has proven in this case to be effective in limiting the growth of this metastatic melanoma without acute adverse effects.

RESUMO

Fibrolamellar hepatocellular carcinoma (FLHCC) is a rare variant of hepatocellular carcinoma (HCC) that commonly affects young individuals without a prior history of liver disease. FLHCC commonly results in a better prognosis than HCC; however, the risk of recurrence and metastatic disease is high. FLHCC is typically treated by primary resection of the tumor with 50-75% cure rates. The use of radiation therapy in FLHCC has not been assessed on its own, and may show some success in a very few reported combination therapy cases. We report on the successful use of radiation therapy in a case of metastatic FLHCC to the lung following primary and secondary resections. Our treatment of the large, metastatic, pulmonary FLHCC tumor with 40 Gy in 10 fractions resulted in an 85.9% tumor volume decrease over six months. This suggests FLHCC may be a radiosensitive tumor and radiotherapy may be valuable in unresectable or metastatic tumors.

RESUMO

Outcomes of external beam radiotherapy (EBRT) in advanced medullary thyroid carcinoma (MTC) are largely unknown. Retrospective review of data from patients with MTC, diagnosed from June 1, 1970, through December 31, 2007. Overall survival and locoregional tumor control rates were calculated. Seventeen patients had adjuvant or palliative EBRT delivered to 41 sites. Six patients initially had adjuvant EBRT (median, 60.80 Gy); none had relapse in the treated area. Five patients with locoregional recurrence after surgery were treated (median, 59.40 Gy), and durable disease control was achieved in 3. Twelve patients received palliative EBRT to 29 sites of metastatic disease (median, 30.00 Gy), which provided sustained symptom relief at 45% of sites. Five- and ten-year overall survival rates were 44% and 19%, respectively. Adjuvant EBRT may be most effective for prevention of locoregional recurrence. EBRT may provide sustained control of advanced, metastatic disease in select patients.

RESUMO

The management of glioblastoma multiforme (GBM) is in most cases complex and must be specifically tailored to the needs of the patient with the goals of extended survival and improved quality of life. Despite advancements in therapy, treatment outcomes remain almost universally poor. Salvage treatment options for the recurrence of the disease is an area of intense study. The following case highlights the utility of Gamma Knife Radiosurgery (GKRS) as a salvage treatment. In this clinical situation, three sequential GKRS treatments led to prolonged survival (beyond four years after diagnosis) and improved quality of life in a patient who was unable to receive further chemotherapy regimens and was unwilling to undergo further aggressive resection. To date, there have been few reports of three or more sequential GKRS treatment sessions utilized as salvage therapy for recurrent GBM in patients who can no longer tolerate chemotherapy. This report provides evidence that aggressive local treatment with GKRS at the time of recurrence may be appropriate, depending on a patient's individual clinical situation, and can lead to prolonged survival and improved quality of life.

RESUMO

PURPOSE: To assess the toxicity and efficacy of intensity modulated radiation therapy (IMRT) combined with chemotherapy in treatment of anal cancer. METHODS AND MATERIALS: We examined the records of 34 consecutive patients who received chemoradiation therapy with IMRT as initial treatment for squamous cell carcinoma of the anus between June 2005 and January 2009. The median radiation dose was 50.4 Gy (range, 48.6-57.6 Gy). Chemotherapy was given concurrently: 5-fluorouracil alone in 1 patient and combination 5-fluorouracil and mitomycin C in all others. Endpoints included local control and survival, as well as toxicity. Acute and late toxicity was scored with the Common Terminology Criteria for Adverse Events version 3.0. RESULTS: Twenty-eight patients presented with T1 and T2 disease and 6 with T3 and T4 disease. Fourteen patients had regional nodal metastases. The median age was 59 years (range, 46-85 years). Median follow-up in surviving patients was 22 months. The estimated 2-year survival was 93% (95% confidence interval, 76%-98%). Three patients (9%) had local relapse (estimated 2-year local control, 90%; 95% confidence interval, 74%-97%). One patient had relapse in a regional node. Acute grade 3-4 hematologic toxicity was observed in 20 patients (59%). Other acute grade 3 or grade 4 toxicity included the gastrointestinal tract in 3 patients (9%) and skin in 5 patients (15%). Two patients (6%) had late grade 3 or grade 4 gastrointestinal tract toxicity. CONCLUSIONS: Treatment of anal squamous cell carcinoma with IMRT and chemotherapy is effective and has an acceptable toxicity profile.

RESUMO

BACKGROUND: We aimed to assess outcomes of patients with anal cancer who underwent intensity-modulated radiotherapy (IMRT) and received less than 1.80 Gy/day. METHODS: We retrospectively reviewed our experience using a low fractional dose (< 1.80 Gy) of IMRT to elective nodal areas for patients receiving chemoradiotherapy for anal cancer. Three-year freedom from any disease relapse and overall survival were estimated using Kaplan-Meier curves. We documented the daily dose that was delivered to clinically uninvolved regions and to areas of gross disease. Incidence of regional failures in high (≥ 1.80 Gy) and low (< 1.80 Gy) daily dose regions was assessed. RESULTS: Thirty-four consecutive patients (median age, 59 years) received IMRT from June 2005 through January 2009. Median follow-up duration was 22 months. Twenty-eight patients had T1 or T2 disease and 6 had T3 or T4 disease. Fourteen patients had nodal metastases. Median treatment dose was 50.40 Gy (range, 48.60-57.60 Gy) in 25 to 32 fractions. The range of fractional doses to clinically negative volumes was 1.28 to 1.80 Gy. Seventeen patients (50%) received a fractional dose of less than 1.60 Gy, 13 (38%) received less than 1.50 Gy, and 9 (26%) received less than 1.40 Gy to at least a portion of the clinically negative volume. Three-year freedom from relapse was 80%, and 3-year overall survival was 87%. No patient had treatment failure in the clinically negative volume that received a low daily dose. CONCLUSIONS: Our data support using doses between 1.50 and 1.80 Gy/day to clinically uninvolved regions.

RESUMO

BACKGROUND AND PURPOSE: Identify the incidence of early pulmonary toxicity in a cohort of patients treated with lung stereotactic body radiation therapy (SBRT) on consecutive treatment days. MATERIAL AND METHODS: A total of 88 lesions in 84 patients were treated with SBRT in consecutive daily fractions (Fx) for medically inoperable non-small cell lung cancer or metastasis. The incidence of pneumonitis was evaluated and graded according to the NCI CTCAE v3.0. RESULTS: With a median follow-up of 15.8 months (range 2.5-28.6), the median age at SBRT was 71.8 years (range 23.8-87.8). 47 lesions were centrally located and 41 were peripheral. Most central lesions were treated with 48Gy in 4 Fx, and most peripheral lesions with 54Gy in 3 Fx. The incidence of grade ≥ 2 pneumonitis was 12.5% in all patients treated, and 14.3% among the subset of patients treated with 54Gy in 3 Fx. A total of two grade 3 toxicities were seen as one grade 5 toxicity in a patient treated for recurrence after pneumonectomy. CONCLUSIONS: Treating both central and peripheral lung lesions with SBRT in consecutive daily fractions in this cohort was well tolerated and did not cause excessive early pulmonary toxicity.

RESUMO

BACKGROUND: Chronic aspirin therapy is recommended by the American College of Cardiology/American Heart Association (ACC/AHA) following acute myocardial infarction (AMI) and by the Society of Thoracic Surgeons(STS) following coronary artery bypass graft (CABG). Aspirin therapy at discharge following a hospitalization for AMI or CABG is a common pay for-performance indicator used by third-party payers and was included asa quality measure in the Centers for Medicare & Medicaid Services (CMS)/Premier Hospital Quality Incentive Demonstration initiated in 2003. A formal prescription for aspirin, such as required for other cardiovascular drugs,could serve as a reminder to all health care providers (doctors, nurses, and pharmacists) to include aspirin on a discharge medication list. OBJECTIVE: To evaluate if an aspirin prescription placed in the patient chart shortly after hospital admission would increase compliance with guidelines for aspirin use at discharge in patients with AMI or CABG. METHODS: This was a single-center prospective pre-intervention to post intervention comparison study in a 411-bed hospital. Patients admitted during the 3-month period from July through September 2008 with an AMI or undergoing CABG surgery served as the pre-intervention group, and patients admitted during the 3-month period from January through March 2009 were in the post-intervention group. The intervention included multiple educational sessions with clinical staff, conducted both prior to and during the pilot, and blank pre-printed aspirin prescriptions placed in the charts of patients for whom no contraindication to aspirin was present. The blank prescriptions were then completed by the attending physician (or physician extender), and the discharge nurse used the completed aspirin prescription, with other prescriptions and written orders, as a reference when creating the discharge medication list. The primary outcome measure was the percentage of patients who had aspirin documented on the discharge medication list. Differences in compliance rates in the comparison and pilot periods were assessed using the Pearson chi-square test. RESULTS: A total of 458 patients were identified with a CABG procedure and/or an admitting diagnosis of AMI; 447 met inclusion criteria, and 11 were excluded (1 patient in each of the groups had a contraindication to aspirin due to bleeding, and 9 died during hospitalization). The intervention was associated with an increase in the proportion of patients with aspirin documented on the discharge medication list, 266 of 269 patients (98.9%)compared with 169 of 178 patients (94.9%, P = 0.012) in the pre-intervention group. In the subsample of patients with CABG, 54 of 59 (91.5%)patients in the pre-intervention group had aspirin documented on the discharge medication list compared with 100% of 66 patients in the postintervention group (P = 0.016). In the subsample of patients with AMI, aspirin was documented in 115 of 119 (96.6%) patients in the pre-intervention group versus 200 of 203 (98.5%) in the post-intervention group (P = 0.263). CONCLUSION: A quality improvement initiative that included clinical staff education and placement of aspirin prescriptions in patient charts during the hospital stay was associated with an increase in the proportion of patients who had aspirin documented on the discharge medication list for the overall sample of patients with AMI or CABG and for patients with CABG alone but not for the quality measure for AMI patients.

RESUMO

OBJECTIVES: To evaluate the incidence of contrast-induced nephropathy (CIN) with the use of an automated contrast injection system in conjunction with contemporary measures to prevent CIN after cardiac catheterization and percutaneous coronary intervention (PCI). BACKGROUND: The use of automated contrast injection systems can reduce the volume of procedural contrast, but whether lower contrast volume is associated with a lower incidence of CIN is uncertain. METHODS: The incidence of CIN was assessed in 1,798 patients after diagnostic catheterization or PCI at Wake Forest University Baptist Medical Center from April 2002 to November 2004 using traditional handheld manifold injection systems, and in 377 subsequent patients using an automated contrast injection system. Preprocedural hydration was used on a routine basis, and N-acetylcysteine and bicarbonate infusion were used on an ad hoc basis. Outcomes were adjusted by standard logistic regression modeling. RESULTS: Mean contrast volume (+/- standard deviation) per case was reduced from 204 +/- 147 ml to 146 +/- 108 ml, p < 0.05 by use of automated contrast injection. The incidence of CIN was 19.3% using manifold injection, and was 13.3%, p < 0.05, after use of automated contrast injection. The use of automated contrast injection was associated with a reduced relative risk of CIN, 0.66 (0.47-0.93), compared to manual injection, even after adjustment for baseline clinical and procedural covariates. CONCLUSIONS: The use of an automated contrast injection system in conjunction with contemporary hydration and pharmacologic strategies to prevent CIN during diagnostic catheterization and PCI was associated with a significant reduction in the use of contrast volume, as well as in the incidence of CIN.

RESUMO

Elevation of white blood cells (WBCs) is associated with worse outcomes in patients with coronary artery disease (CAD), including patients undergoing percutaneous coronary intervention (PCI) of native coronary arteries, but this relation has not been studied in patients with saphenous vein graft disease undergoing PCI. A total of 530 patients who underwent PCI of saphenous vein grafts from May 1997 to July 2002 were followed for >3 years. Major adverse coronary events (MACEs) were assessed as a composite of death, myocardial infarction, or revascularization during follow-up (mean 2.7 years). Patients with MACEs (n = 287) were younger and had more thrombotic and ostial lesions (p < 0.05) than those without MACEs (n = 243). The preprocedural WBC count was also significantly higher in the MACE group than in the non-MACE group (8.1 x 10(3)/mul, range 6.6 to 10.1, vs 7.0 x 10(3)/mul, range 5.6 to 8.2; p < 0.001). After adjusting for covariates, multiple logistic regression analysis revealed the preprocedural WBC count to be an independent predictor for MACEs (odds ratio 1.2; 95% confidence interval 1.1 to 1.3, p < 0.001). Patients in the highest quartile of the preprocedural WBC level had a significantly increased risk of MACEs (lowest vs highest quartile, 41.3% vs 72.4%; odds ratio 3.7; 95% confidence interval 2.2 to 6.3). Thus, an elevated preprocedural WBC count is associated with increased risk of MACEs in patients undergoing PCI for saphenous vein graft lesions.
