RESUMO

PURPOSE: The impact of age on optimal management of glioblastoma remains unclear. A recent combined analysis of two randomised trials, GEINO14-01 and EX-TEM, found no benefit from extending post-radiation temozolomide in newly diagnosed glioblastoma. Here, we explore the impact of age. METHODS: Relevant intergroup statistics were used to identify differences in tumour, treatment and outcome characteristics based on age with elderly patients (EP) defined as age 65 years and over. Survival was estimated using the Kaplan Meier method. RESULTS: Of the combined 205 patients, 57 (28%) were EP. Of these, 95% were ECOG 0-1 and 65% underwent macroscopic resection compared with 97% and 61% of younger patients (YP) respectively. There were numerically less MGMT-methylated (56% vs. 63%, p = 0.4) and IDH-mutated (4% vs. 13%, p = 0.1) tumours in EP vs. YP. Following surgery, EP were more likely to receive short course chemoradiation (17.5% vs. 6%, p = 0.017). At recurrence, EP tended to receive or best supportive care (28.3% vs. 15.4%, p = 0.09) or non-surgical options (96.2% vs. 84.6%, p = 0.06), but were less likely to receive bevacizumab (23.1% vs. 49.5%, p < 0.01). Median PFS was similar at 9.3months in EP and 8.5months in YP, with similar median OS at 20months. CONCLUSION: In this trial population of predominantly fit EP, survival was similar to YP despite a proportion receiving less aggressive therapy at diagnosis and recurrence. Advancing age does not appear to be an adverse prognostic factor for glioblastoma when patients are fit for treatment, and a less aggressive approach in selected patients may not compromise outcomes.

RESUMO

PURPOSE: The optimal duration of post-radiation temozolomide in newly diagnosed glioblastoma remains unclear, with no published phase III randomised trials. Standard-of-care stipulates 6 months. However, in routine care, it is often extended to 12 months, despite lacking robust supporting data. METHODS: GEINO14-01 (Spain) and EX-TEM (Australia) studies enrolled glioblastoma patients without progression at the end of 6 months post-radiation temozolomide. Participants were randomised 1:1 to six additional months of temozolomide or observation. Primary endpoint was 6-month progression free survival from date of randomisation (6mPFS). Secondary endpoints included overall survival (OS) and toxicity. 204 patients were required to detect an improvement in 6mPFS from 50 to 60% (80% power). Neither study recruited sufficient patients. We performed a combined analysis of individual patient data. RESULTS: 205 patients were recruited: 159 in GEINO14-01 (2014-2018) and 46 in EX-TEM (2019-2022). Median follow-up was 20.0 and 14.5 months. Baseline characteristics were balanced. There was no significant improvement in 6mPFS (57.2% vs 64.0%, OR0.75, p = 0.4), nor across any subgroups, including MGMT methylated; PFS (HR0.92, p = 0.59, median 7.8 vs 9.7 months); or OS (HR1.03, p = 0.87, median 20.1 vs 19.4 months). During treatment extension, 64% experienced any grade adverse event, mainly fatigue and gastrointestinal (both 54%). Only a minority required treatment changes: 4.5% dose delay, 7.5% dose reduction, 1.5% temozolomide discontinuation. CONCLUSION: For glioblastoma patients, extending post-radiation temozolomide from 6 to 12 months is well tolerated but does not improve 6mPFS. We could not identify any subset that benefitted from extended treatment. Six months should remain standard-of-care.

RESUMO

Purpose: We retrospectively examined the potential effect on overall survival (OS) of delaying radiotherapy to administer neoadjuvant therapy in unresected glioblastoma patients. Patients and methods: We compared OS in 119 patients receiving neoadjuvant therapy followed by standard treatment (NA group) and 96 patients receiving standard treatment without neoadjuvant therapy (NoNA group). The MaxStat package of R identified the optimal cut-off point for waiting time to radiotherapy. Results: OS was similar in the NA and NoNA groups. Median waiting time to radiotherapy after surgery was 13 weeks for the NA group and 4.2 weeks for the NoNA group. The longest OS was attained by patients who started radiotherapy after 12 weeks and the shortest by patients who started radiotherapy within 4 weeks (12.3 vs 6.6 months) (P = 0.05). OS was 6.6 months for patients who started radiotherapy before the optimal cutoff of 6.43 weeks and 19.1 months for those who started after this time (P = 0.005). Patients who completed radiotherapy had longer OS than those who did not, in all 215 patients and in the NA and NoNA groups (P = 0.000). In several multivariate analyses, completing radiotherapy was a universally favorable prognostic factor, while neoadjuvant therapy was never identified as a negative prognostic factor. Conclusion: In our series of unresected patients receiving neoadjuvant treatment, in spite of the delay in starting radiotherapy, OS was not inferior to that of a similar group of patients with no delay in starting radiotherapy

RESUMO

Anthracycline and taxane-based primary chemotherapy (PCT) is the standard treatment for high-risk breast cancer (HRBC). However, conventional anthracyclines are not commonly used in elderly patients or those prone to cardiotoxicity. Pegylated liposomal doxorubicin, (PLD) has comparable efficacy, but less cardiotoxicity than conventional anthracyclines. We conducted a phase II single-arm trial to assess the efficacy and safety of PCT based on PLD followed by paclitaxel (PTX) in a HRBC population usually undertreated. Fifty patients with stage II-IIIB breast cancer and at least one risk factor for developing cardiotoxicity initiated PLD 35 mg/m(2) plus cyclophosphamide 600 mg/m(2) every 4 weeks for four cycles, followed by 80 mg/m(2) weekly PTX for 12. Close cardiac monitoring was performed. Primary endpoint was the pathological complete response rate (pCR) in the breast. Treatment delivery and toxicities were assessed. Eighty-four per cent of patients were older than 65 years, 64 % suffered from hypertension, and 10 % had prior cardiac disease. In an intention-to-treat analysis, breast pCR was 32 % (95 % CI 19.5-46.7 %) and pCR in breast and axilla was 24 % (95 % CI 12.1-35.8 %). At diagnosis only, 26 % of patients were candidates for breast conservative surgery, which increased to 58.7 % after PCT. No significant decrease in left ventricular ejection fraction was seen. PLD followed by PTX was feasible in a fragile population of patients who were not candidates for conventional doxorubicin. Moreover, it achieved a pCR similar to standard therapy and could therefore be an option for elderly patients or cardiotoxicity-prone who present HRBC.

RESUMO

UNLABELLED: New therapeutic approaches are being developed based on the findings that several genetic abnormalities underlying NSCLC could influence chemosensitivity. In this study, we assessed whether the presence of polymorphisms in ERCC1, XPD, RRM1 and MDR1 genes can affect the efficacy and the tolerability of cisplatin and vinorelbine in NSCLC patients. MATERIAL AND METHODS: Eligible patients had histological confirmed stage IV or IIIB (with malignant pleural effusion) non-small-cell lung cancer (NSCLC) previously untreated with chemotherapy; World Health Organization performance status (PS) 0-1. Patients received intravenous doses of vinorelbine 25 mg/m² on day 1 and 8 and cisplatin 75 mg/m² on day 1, every 21 days, for a maximum of eight cycles. RESULTS: 94 patients were included. Median age was 61 years; 84% were male; WHO performance status (PS) was 0 in 24%; and 88% of patients had stage IV disease. The median number of cycles was 6. Overall median survival was 10.92 months (95% CI 9.0-12.9). Overall median time to progression was 5.89 months (95% CI 5.2-6.6). Results of the multivariate analysis for time to progression showed that ECOG 0 (hazard ratio [HR] ECOG 1 vs. ECOG 0, 1.74; p=0.036), MDR13435CC (HR CT vs. CC, 2.01; p=0.017; HR TT vs. CC, 1.54; p=0.22), and decreasing age (HR of age, 0.97; p=0.016) were the most powerful prognostic factors significantly related to lower risk of progression. Whereas ECOG 0 was the only prognostic factor for survival (HR ECOG 1 vs. ECOG 0, 3.02; p=0.001). There was no significant association between any of the SNPs analysed and the occurrence of vinorelbine and cisplatin-related toxicity. CONCLUSION: In our results, the most important prognostic factors associated with lower risk of progression were MDR1 3435 CC genotype, PS 0 and younger age.

RESUMO

Anomalous aortic origin of a coronary artery found in a symptomatic 9-year-old boy was initially treated with coronary artery bypass grafting using a left internal mammary artery anastomoses to the left anterior descending coronary artery, but resulted in coronary ischemia, likely from a steal phenomenon. Subsequent transection of the proximal left internal mammary artery with anastomosis to the ascending aorta, and coronary ostial enlargement, resulted in a durable treatment. We recommend caution in choosing coronary artery bypass grafting using a left internal mammary artery pedicle graft for the treatment of anomalous aortic origin of a coronary artery.

RESUMO

OBJECTIVES: Results of Fontan's procedure have improved considerably, but perioperative mortality still occurs, attributed to ventricular dysfunction, stroke, arrhythmia, thromboembolism, and multi-organ dysfunction. Our protocols of operative and intensive care unit management address these potential issues, and have been associated with zero mortality, even with many high-risk candidates. METHODS: From 1996 to 2006, all Fontan patients were managed as follows: operative strategy based on aortic and single atrial cannulation, cooling on full-flow bypass, and hypothermic circulatory arrest to create the Fontan pathway. No direct caval cannulation. Use of central venous lines was completely avoided. Fresh whole blood was used for pump prime and for volume restoration. Inotropic and vasodilator therapy was continued for at least 48 h. Aspirin was used exclusively as anti-thrombotic therapy. Postoperative pleural drainage was accomplished with small pigtail catheters. The usual Fontan pathway was by lateral atrial tunnel (84), with extra-cardiac conduit when dictated by anatomy (16). RESULTS: One hundred Fontan operations were performed with no mortality. All patients were extubated by postoperative day 1. Hospital stay was 10+/-5 days. Complications were: bleeding (1), reintubation (1), emergent fenestration closure (1), pericardial effusion (4), and seizures (1). Risk factors included Fontan connection to one lung (3), diminutive pulmonary arteries (PAs) and unifocalized major aortopulmonary collateral arteries (MAPCAs) (1), discontinuous PAs (3), right ventricle dependent coronaries (3), neonatal pulmonary venous obstruction (3), Trisomy 21 (1), preoperative pacemaker dependence (2), and heterotaxy (10). No candidate was excluded. CONCLUSIONS: While many surgeons try to avoid bypass or aortic clamping when performing Fontan operations, the strategies we have employed facilitate safe accomplishment of Fontan's operation in diverse anatomic groups with multiple risk factors, with avoidance of operative mortality in 100 consecutive cases.

RESUMO

OBJECTIVES: Cisplatin-based combination chemotherapy is the mainstay of treatment for advanced bladder cancer. However, full doses of cisplatin cannot be delivered in patients with impaired renal function. Our aim was to prove the feasibility of a gemcitabine and low-dose cisplatin regimen, delivered every two weeks in patients with impaired renal function. MATERIAL AND METHODS: Patients with locally advanced or metastatic bladder cancer with creatinine clearance between 35-60 ml/min received gemcitabine 2500 mg/m2 and cisplatin 35 mg/m2 on day 1, every 14 days. RESULTS: Between January 2004 and March 2005, 17 patients were treated. Mean creatinine clearance was 47.8 ml/min (range: 37-59 ml/min). Four patients had previously received chemotherapy with gemcitabine and/ or platinum. Median number of cycles per patient was 5 (1-13). No patient developed renal toxicity or worsening of renal function. Main toxicities were (grade 3/4): Anemia 2/1; leucopenia: 1/2; trombopenia 1/1. There was one toxic death related to metabolic acidosis, secondary to vomiting. Among 16 patients evaluable for response, we observed one complete response, 7 partial responses (ORR: 53.3%; IC 95%: 28.1-78.5%), 6 stabilizations (37.5%) and 2 progressions (12.5%). CONCLUSIONS: Gemcitabine and low-dose cisplatin is a safe and feasible combination in patients with poor renal function. Response rates seem similar to those previously described with standard schedules of this combination (AU)

RESUMO

BACKGROUND: To determine outcomes for the arterial switch operation individualized according to the underlying anatomy and clinical status. METHODS: A retrospective review of a consecutive series of infants less than 90 days of age who underwent the arterial switch operation at a single institution. RESULTS: From July 1993-April 2001, 117 infants underwent an arterial switch operation before 90 days of age. Seventy-five patients (64%) had transposition of the great arteries with intact ventricular septum with the aim of operation before 14 days of age; however, 8 of these patients had delayed presentation (range 15-46 days). Thirty-five patients (30%) had transposition with a ventricular septal defect (30 patients) or double outlet right ventricle (5 patients) and normal arch anatomy and were repaired within the first 90 days of life depending on the severity of heart failure at a median of 12 days of age (range 3-83 days). Seven patients (6%) had associated aortic coarctation (5 patients) or interrupted aortic arch (2 patients). One patient died during hospitalization (0.85% hospital mortality) and one patient died from noncardiac causes during a median follow-up of 35 months (1.7% total mortality). Four patients required intervention during follow-up (3.4%) for new aortic coarctation (2 patients), supravalvar pulmonic stenosis (1 patient), or right hemi-diaphragm paralysis (1 patient). CONCLUSIONS: Individualized timing for the arterial switch operation within the first ninety days of life produces excellent survival rates for all types of transposition physiology with the expectation of a satisfactory course during follow-up.

RESUMO

Although transesophageal echocardiography is often used for guidance during transcatheter interventions, few data exist regarding the use of the newer modality of intracardiac echocardiography. This brief report summarizes our single center experience using intracardiac echocardiographic guidance during transcatheter interventional procedures for congenital heart disease.

RESUMO

OBJECTIVE: To assess the results of a staged surgical approach for tetralogy of Fallot with pulmonary atresia, hypoplastic or absent pulmonary arteries, and major aortopulmonary collateral arteries. METHODS: We retrospectively reviewed a consecutive series of these patients from a single institution. RESULTS: From July 1993 to April 2001, 46 consecutive patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collateral arteries were treated with staged surgical repair. The operative sequence usually began with a central aortopulmonary shunt followed by unifocalization of aortopulmonary collateral arteries depending on the source and distribution of pulmonary blood flow. Twenty-eight patients (61%) subsequently underwent complete repair with ventricular septal defect closure and right ventricle to pulmonary artery connection. Those patients who underwent complete repair had a median of 3 total operations (range 1-6). The ratio of the mean pulmonary artery pressure to the mean systemic blood pressure at the time of complete repair was 0.36 (range 0.19-0.58). Two of the 28 repaired patients (7.1%) required subsequent fenestration of the ventricular septal defect closure due to later development of supersystemic right ventricular pressure and right ventricular failure. Eighteen patients (39%) have undergone 1 or more staging operations and are considered good candidates for eventual complete repair. There were no hospital deaths. There was 1 late death (2.2%; 95% CI 0.4-11.3%) in a patient born prematurely who developed severe bronchopulmonary dysplasia precluding complete repair. CONCLUSIONS: For tetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries, a staged surgical approach yields low overall mortality and acceptable hemodynamics after complete repair.

RESUMO

BACKGROUND: Pulmonary vein stenosis has recently been recognized as a complication of radiofrequency ablation for atrial fibrillation. This study evaluates the presentation of affected patients and the role of transcatheter therapy for this patient population. METHODS AND RESULTS: This study used a retrospective review of data from 19 patients (age, 51+/-13 years) with pulmonary vein stenosis who underwent catheterization and angiography between December 2000 and December 2002. Quantitative perfusion and spiral CT scans were performed for initial diagnosis and follow-up. The median duration between radiofrequency ablation and the reported onset of respiratory symptoms for 18 of 19 patients was 7.5 weeks (0.1 to 48). After the onset of symptoms, all but two patients were initially misdiagnosed with a symptoms-to-diagnosis duration of 16 weeks (2-59). At initial catheterization, 17 of 19 patients had angioplasty in 30 veins with stent placement in 5 vessels when a flap occurred. Overall vessel diameter increased from 2.6+/-1.6 to 6.6+/-2.4 mm (P<0.0001). There were 4 procedure-related adverse events but no long-term sequelae. Immediate follow-up showed improved flow to involved lung segments. At a median follow-up of 43 weeks (2-92), although repeat angioplasty for restenosis was necessary in 8 of 17 patients, 15 of 17 patients currently have no or minimal persistent symptoms. CONCLUSIONS: Pulmonary vein stenosis after radiofrequency ablation for atrial fibrillation is often misdiagnosed. Although further follow-up is necessary to determine long-term success, our data indicate better pulmonary vein flow and symptomatic improvement in the majority of patients undergoing dilation of postablation pulmonary vein stenosis.

RESUMO

OBJECTIVE: To determine the outcomes for a program that utilizes the double switch operation as the primary approach for congenitally corrected transposition. METHODS: The records of 46 consecutive patients from a single institution who had undergone a double switch operation from October 1993 to March 2002 were reviewed. The records of 24 patients who were evaluated during the same period and felt not to be candidates for the double switch operation or who are awaiting double switch after pulmonary artery banding were also reviewed. RESULTS: The median age at operation was 28 months (range 2 months to 16.3 years). Associated defects included ventricular septal defect 40, pulmonic stenosis 13 and pulmonary atresia 16. Twenty-six patients underwent an arterial switch operation combined with a Senning procedure while 20 patients underwent combined Rastelli and Senning procedures. Before the double switch, 12 patients had required pulmonary artery banding and 21 patients had systemic to pulmonary artery shunts. The median duration of stay in the intensive care unit was 3.5 days (range 2-60 days) and the median duration of total hospital stay was 8 days (range 5-60 days). There were no hospital deaths; one patient died 5 months after discharge due to an arrhythmogenic cardiac arrest during a median follow-up of 24 months [long-term survival 98% (95% CI 89-100%)]. CONCLUSIONS: The double switch operation may be performed with excellent hospital and long-term survival. The theoretical advantages of this procedure which enables the morphologic left ventricle and mitral valve to support a systemic pressure load must be established by careful follow-up of these patients.

RESUMO

OBJECTIVE: Results of the repair of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) have improved. Direct implantation of the anomalous coronary artery into the ascending aorta establishes a dual-coronary system and is the goal of current surgical approaches. We report the development of our surgical technique for ALCAPA. METHODS: Between September 1993 and December 2000, 13 patients underwent surgery for ALCAPA. There were four males and nine females. Ages ranged from 1 month to 25 years (median=3.9) and weight ranged from 2.6 to 102kg (median=16.8). One patient had previously undergone an operative procedure at an outside institution. RESULTS: Direct implantation of the anomalous coronary artery into the ascending aorta was feasible in 12 of 13 patients. In situ transfer was performed in one patient with an intramural coronary artery. The first case in the series required an intrapulmonary baffle reconstruction (Takeuchi procedure) because the coronary artery arose remotely from the ascending aorta from the left-anterior sinus of the PA. For coronary transfer, a trapdoor flap was created on the ascending aorta for the implantation of the coronary button and the sinus defect in the main PA was augmented with a pericardial patch. The left ventricular (LV) shortening fraction was improved from a median value of 27% (range 12-36%) preoperatively to 33% (range 24-45%) in the immediate postoperative period (P=0.004). The LV end-diastolic dimension decreased from a median value of 36 mm (range 22-70 mm) preoperatively to 29 mm (range 19-56 mm) in the immediate postoperative period (P=0.004). There has been no mortality or reoperation during a median follow-up of 36 months. CONCLUSIONS: Using a standard technique, direct implantation of the anomalous coronary artery into the ascending aorta was achieved in all cases but one. At intermediate follow-up, LV function had improved by echocardiography. No postoperative mechanical circulatory support was required in any of these patients. This operative technique is reproducible and is applicable to the majority of patients with ALCAPA.

RESUMO

Propósito: Descripción de un caso de metástasis muscular como primera manifestación de un Carcinoma de Células Renales (CCR).Material y métodos: Presentamos el caso de una paciente afectada de metástasis muscular de un carcinoma de células renales, la actitud diagnóstica, valoración terapéutica y evolución. Resultados: Se analizan las peculiaridades de la evolución y tratamiento del CCR metastásico. En nuestro caso se inició un tratamiento de combinación con Interferón alfa-2b e Interleukina-2 recombinate (IFN+ IL-2r) que no pudo evitar la rápida progresión de la enfermedad y la muerte de la paciente a los 5 meses del diagnóstico. Conclusiones: La elección del tratamiento en pacientes con CCR metastásico debe ser individualizada en función de los datos obtenidos en el estudio de extensión y de la valoración de los factores pronósticos de la evolución de la enfermedad (AU)

RESUMO

Patients with complex congenital heart disease may have pulmonary artery stenoses that are either congenital or associated with scarring following surgical procedures. This study evaluates cutting balloon angioplasty for small-vessel pulmonary artery stenoses resistant to standard balloon angioplasty. Between October 1998 and December 1999, patients were enrolled in an FDA-approved compassionate-use protocol. During four catheterizations, there were seven lesions found resistant to standard balloon angioplasty (mean lesion diameter was unchanged: 1.8 mm +/- 0.8 mm to 1.9 +/- 0.8 mm). A cutting balloon was inflated twice in each of these lesions. Standard balloon angioplasty was then repeated. Final mean lesion diameter was increased significantly (1.9 mm +/- 0.8 mm to 3.8 +/- 1.3 mm; P

RESUMO

We report a case of a neonate with multiple cardiac masses, cyanosis, and a heart murmur. Arterial desaturation was the result of right-to-left shunting at the foramen ovale level caused by tricuspid regurgitation. Three right-sided cardiac masses were detected by echocardiography. By 2 weeks of age the patient had complete resolution of his cyanosis and improved tricuspid regurgitation following the normal decrease in pulmonary vascular resistance. At 2 years of age, he has no cardiovascular symptoms and the masses are calcified and have no hemodynamic consequences.

RESUMO

Surgical management of patent ductus arteriosus (PDA) in the elderly population is complicated by a fragile aortic wall due to atheromatous lesions, the presence of friable tissue at the surgical site, and calcification of the ductus. A viable option for the elderly patient is transcatheter closure of the PDA using a synthetic plug. Transcatheter coil occlusion has been shown to be an effective nonsurgical technique for closure of the persistently PDA in a younger population. We report a case of a 75 year old woman who had complete occlusion of her PDA with a single Gianturco coil after recurrence of her ductus 3 years post surgical ligation. The successful transcatheter treatment is presented with emphasis on the simple and safe technique utilized. (c)1999 by CVRR, Inc.
