Impact of age and comorbidities on long-term survival of patients with high-risk prostate cancer treated with radical prostatectomy: a multi-institutional competing-risks analysis

Survival after surgical treatment using competing-risk analysis has been previously examined in patients with prostate cancer (PCa). However, the combined effect of age and comorbidities has not been assessed in patients with high-risk PCa who might have heterogeneous rates of competing mortality despite the presence of aggressive disease.

Outcome predictors of radical prostatectomy followed by adjuvant androgen deprivation in patients with clinical high risk prostate cancer and pT3 surgical margin positive disease

Patients with high risk prostate cancer with pT3 tumor and positive surgical margins have a high risk of biochemical failure after radical prostatectomy and adjuvant androgen deprivation therapy. Predictors of cancer related death in this patient group are necessary.

The role of adjuvant hormonal treatment after surgery for localized high-risk prostate cancer: results of a matched multiinstitutional analysis

Introduction. To assess the role of adjuvant androgen deprivation therapy (ADT) in high-risk prostate cancer patients (PCa) after surgery. Materials and Methods. The analysis case matched 172 high-risk PCa patients with positive section margins or non-organ confined disease and negative lymph nodes to receive adjuvant ADT (group 1, n = 86) or no adjuvant ADT (group 2, n = 86). Results. Only 11.6% of the patients died, 2.3% PCa related. Estimated 5-10-year clinical progression-free survival was 96.9% (94.3%) for group 1 and 73.7% (67.0%) for group 2, respectively. Subgroup analysis identified men with T2/T3a tumors at low-risk and T3b margins positive disease at higher risk for progression. Conclusion. Patients with T2/T3a tumors are at low-risk for metastatic disease and cancer-related death and do not need adjuvant ADT. We identified men with T3b margin positive disease at highest risk for clinical progression. These patients benefit from immediate adjuvant ADT.

Radical prostatectomy in very high-risk localized prostate cancer: long-term outcomes and outcome predictors

The objective of this study was to present the long-term outcomes and determine outcome predictors in very high-risk (cT3b-T4) prostate cancer (PCa) after radical prostatectomy (RP).

Debulking surgery in the setting of very high-risk prostate cancer scenarios

What's known on the subject? and What does the study add? Nowadays radical prostatectomy (RP) is considered an effective treatment in high-risk prostate cancer (PCa) and the indications for a surgical approach are expanding, even in cases of very high PSA or node-positive disease. We explored the outcomes of debulking surgery in the setting of these very high-risk PCa patients, in order to assess its feasibility. This review confirms the important role achieved by surgery in the complex setting of patients with very high-risk PCA. Excellent survival rates have been reported, even when PSA exceeds 100 ng/mL. The completion of RP with lymphadenectomy might give a survival benefit in patients who were found intraoperatively to be node-positive. Furthermore, salvage RP confirmed to be the most effective treatment option after RT failure. On the contrary, up-to-date surgery of isolated nodal recurrences has shown only little benefit. Finally, there is no evidence supporting the efficacy of debulking surgery in metastatic or in hormone-refractory tumours. An accurate selection of the patient is essential.

Identifying the best candidate for radical prostatectomy among patients with high-risk prostate cancer

The current role of radical prostatectomy (RP) in patients with high-risk disease remains controversial.

Multicycle dose-intensive chemotherapy for women with high-risk primary breast cancer: results of International Breast Cancer Study Group Trial 15-95

PURPOSE: To compare adjuvant dose-intensive epirubicin and cyclophosphamide chemotherapy administered with filgrastim and progenitor cell support (DI-EC) with standard-dose anthracycline-based chemotherapy (SD-CT) for patients with early-stage breast cancer and a high risk of relapse, defined as stage II disease with 10 or more positive axillary nodes; or an estrogen receptor-negative or stage III tumor with five or more positive axillary nodes. PATIENTS AND METHODS: Three hundred forty-four patients were randomized after surgery to receive seven cycles of SD-CT over 22 weeks, or three cycles of DI-EC (epirubicin 200 mg/m2 plus cyclophosphamide 4 gm/m2 with filgrastim and progenitor cell support) over 6 weeks. All patients were assigned tamoxifen at the completion of chemotherapy. The primary end point was disease-free survival (DFS). RESULTS: After a median follow-up of 5.8 years (range, 3 to 8.4 years), 188 DFS events had occurred (DI-EC, 86 events; SD-CT, 102 events). The 5-year DFS was 52% for DI-EC and 43% for SD-CT, with hazard ratio of DI-EC compared with SD-CT of 0.77 (95% CI, 0.58 to 1.02; P = .07). The 5-year overall survival was 70% for DI-EC and 61% for SD-CT, with a hazard ratio of 0.79 (95% CI, 0.56 to 1.11; P = .17). There were eight cases (5%) of anthracycline-induced cardiomyopathy (two fatal) among those who received DI-EC. Women with hormone receptor-positive tumors benefited significantly from DI-EC. CONCLUSION: There was a trend in favor of DI-EC with respect to disease-free survival. A larger trial or meta-analysis will be required to reveal the true effect of dose-intensive therapy.

Multicentre study on peri- and postoperative central venous oxygen saturation in high-risk surgical patients

Introduction Low central venous oxygen saturation (ScvO2) has been associated with increased risk of postoperative complications in high-risk surgery. Whether this association is centre-specific or more generalisable is not known. The aim of this study was to assess the association between peri- and postoperative ScvO2 and outcome in high-risk surgical patients in a multicentre setting. Methods Three large European university hospitals (two in Finland, one in Switzerland) participated. In 60 patients with intra-abdominal surgery lasting more than 90 minutes, the presence of at least two of Shoemaker's criteria, and ASA (American Society of Anesthesiologists) class greater than 2, ScvO2 was determined preoperatively and at two hour intervals during the operation until 12 hours postoperatively. Hospital length of stay (LOS) mortality, and predefined postoperative complications were recorded. Results The age of the patients was 72 ± 10 years (mean ± standard deviation), and simplified acute physiology score (SAPS II) was 32 ± 12. Hospital LOS was 10.5 (8 to 14) days, and 28-day hospital mortality was 10.0%. Preoperative ScvO2 decreased from 77% ± 10% to 70% ± 11% (p < 0.001) immediately after surgery and remained unchanged 12 hours later. A total of 67 postoperative complications were recorded in 32 patients. After multivariate analysis, mean ScvO2 value (odds ratio [OR] 1.23 [95% confidence interval (CI) 1.01 to 1.50], p = 0.037), hospital LOS (OR 0.75 [95% CI 0.59 to 0.94], p = 0.012), and SAPS II (OR 0.90 [95% CI 0.82 to 0.99], p = 0.029) were independently associated with postoperative complications. The optimal value of mean ScvO2 to discriminate between patients who did or did not develop complications was 73% (sensitivity 72%, specificity 61%). Conclusion Low ScvO2 perioperatively is related to increased risk of postoperative complications in high-risk surgery. This warrants trials with goal-directed therapy using ScvO2 as a target in high-risk surgery patients.

[Precancerous and high risk lesions of the oral mucosa--Diagnosis, therapy and follow-up in two cases]

Stomatologic lesions at risk to develop an oral squamous cell carcinoma (OSCC) such as oral leukoplakia, erythroplakia/erythroleukoplakia, or oral lichen planus, need an early detection, diagnosis and a long-term/lifelong follow-up to prevent malignant transformation. In the following report, two patients are presented with oral mucosal lesions, who were referred, diagnosed, treated, and underwent follow-up examinations at the Stomatology Service of the Department of Oral Surgery and Stomatology at the University of Bern. These two cases emphasize the importance of early detection and managment of precancerous lesions or initial stages of OSCC. Additionally, risk factors, such as tobacco and alcohol consumption and their influence on stomatologic lesions and their prognosis, will be discussed.

Percutaneous aortic valve replacement for severe aortic stenosis in high-risk patients using the second- and current third-generation self-expanding CoreValve prosthesis: device success and 30-day clinical outcome

OBJECTIVES: We sought to determine both the procedural performance and safety of percutaneous implantation of the second (21-French [F])- and third (18-F)-generation CoreValve aortic valve prosthesis (CoreValve Inc., Irvine, California). BACKGROUND: Percutaneous aortic valve replacement represents an emerging alternative therapy for high-risk and inoperable patients with severe symptomatic aortic valve stenosis. METHODS: Patients with: 1) symptomatic, severe aortic valve stenosis (area <1 cm2); 2) age > or =80 years with a logistic EuroSCORE > or =20% (21-F group) or age > or =75 years with a logistic EuroSCORE > or =15% (18-F group); or 3) age > or =65 years plus additional prespecified risk factors were included. Introduction of the 18-F device enabled the transition from a multidisciplinary approach involving general anesthesia, surgical cut-down, and cardiopulmonary bypass to a truly percutaneous approach under local anesthesia without hemodynamic support. RESULTS: A total of 86 patients (21-F, n = 50; 18-F, n = 36) with a mean valve area of 0.66 +/- 0.19 cm2 (21-F) and 0.54 +/- 0.15 cm2 (18-F), a mean age of 81.3 +/- 5.2 years (21-F) and 83.4 +/- 6.7 years (18-F), and a mean logistic EuroSCORE of 23.4 +/- 13.5% (21-F) and 19.1 +/- 11.1% (18-F) were recruited. Acute device success was 88%. Successful device implantation resulted in a marked reduction of aortic transvalvular gradients (mean pre 43.7 mm Hg vs. post 9.0 mm Hg, p < 0.001) with aortic regurgitation grade remaining unchanged. Acute procedural success rate was 74% (21-F: 78%; 18-F: 69%). Procedural mortality was 6%. Overall 30-day mortality rate was 12%; the combined rate of death, stroke, and myocardial infarction was 22%. CONCLUSIONS: Treatment of severe aortic valve stenosis in high-risk patients with percutaneous implantation of the CoreValve prosthesis is feasible and associated with a lower mortality rate than predicted by risk algorithms.

Staged bilateral carotid stenting, an effective strategy in high-risk patients - insights from a prospective multicenter trial

OBJECTIVE: To prospectively evaluate outcomes of high-risk patients undergoing bilateral carotid artery stenting (CAS). METHODS: A total of 747 patients at increased risk for carotid endarterectomy (CEA) were enrolled in a prospective registry at 47 US sites of the Boston Scientific EPI: A Carotid Stenting Trial for Risk Surgical Patients (BEACH) trial. Among them, 78 (10.4%) patients underwent contralateral CAS > 30 days after the primary CAS procedure. Patients were followed at 1, 6, and 12 months, and annually thereafter for 3 years. The primary endpoint was the cumulative incidence of non Q-wave myocardial infarction within 24 hours, periprocedural (high-risk for CEA with no increase in morbidity or mortality results extended out to one year in a prospective multicenter trial.
