Abstract Dicliptera squarrosa Nees, “canario rojo”, “coral de campo” or “ajicillo”, is a perennial native herb of the north, center and east of Argentina. It is cited as an ornamental, apiarian, emergency forage plant, and as a glyphosate-tolerant weed. The objectives were to characterize the seed and seedling of D. squarrosa and to establish the relationships with the structures that ensure its survival. The materials were treated with the conventional methodology to perform morphological studies, using stereoscopically and optical microscopy. The germination assays were carried out to determine the germination percentage and the germination type. The weight of… More >

Abstract Purpose: Retroperitoneal lymph nodes are a recognized site of relapse in patients undergoing nephroureterectomy (NU) for high grade upper tract urothelial carcinoma (UC). Retrospective studies suggest that retroperitoneal lymph node dissection (RPLND) may be curative at the time of NU for high grade upper tract UC. We hypothesized that chemotherapy followed by RPLND may successfully salvage select patients with isolated retroperitoneal relapse of upper tract UC following prior NU.
Materials and methods: We identified four patients with metastatic UC isolated to the subdiaphragmatic retroperitoneal lymph nodes after NU for upper tract UC. These patients had either a… More >

Abstract Introduction: Variant histological subtypes of prostatic cancer occur uncommonly and are associated with poor survival, as has been ascertained through limited series and case reports. Here a population-based analysis of prostatic cancer is provided, to better analyze the survival behavior of these subtypes.
Materials and methods: The American SEER registry was used to review prostatic cancer diagnosed from 1988 to 2003, classified according to the International Classification of Diseases for Oncology. Kaplan-Meier and proportional hazards analyses were performed on adenocarcinomas and five infrequent variant subtypes to determine their overall survival behavior, allowing corrections for follow up inequity,… More >

Abstract Case report: A renal cell cancer patient with late onset of multiorgan metastases showed an unusually long survival following surgical resection. Femoral metastasis appeared 11 years, and contralateral kidney and adrenal gland metastasis 19 years after the primary nephrectomy, respectively. Following the resection of the femur and implantation of endoprosthesis and removal of adrenal gland and partial nephrectomy, the patient was disease-free 20 years after the first diagnosis of cancer.
Conclusion: The long survival and successful treatment underline the importance and efficiency of radical metastasectomy even in the case of late onset multiorgan metastases of renal cell More >

Abstract Introduction: Leiomyosarcoma of the kidney and renal pelvis is a rare tumor that, on the basis of limited data, has been ascribed a particularly poor prognosis compared to other subtypes of renal malignancy. Here the population-based Surveillance, Epidemiology, and End Results (SEER) registry is used to study the survival of renal leiomyosarcomas.
Methods: There were 95,935 cases of invasive cancer of the kidney and renal pelvis retrieved from the SEER registry to provide 112 cases of leiomyosarcoma. Kaplan-Meier survival estimates and Cox proportional hazard models were constructed to compare the survival of leiomyosarcomas to other renal… More >

Abstract Introduction: Radical cystectomy (RC) with urinary diversion remains as one of the more complex urological procedures despite considerable progress in surgical technique. Increasing patient age, along with associated age-related comorbidities, may portend a poor outcome in those undergoing such complicated surgical procedures. Herein, we report our experience with radical cystectomy in the elderly population.
Methods: We retrospectively reviewed our RC results from 1995 to 2003. Patients ≥80 years old were included in this analysis. Perioperative outcomes, as well as overall and disease-free survival were evaluated.
Results: A total of 517 patients underwent RC with urinary diversion during… More >

Abstract Background: Wilms' Tumor is the most common malignant neoplasm of the urinary tract in children. Since 1969, the National Wilms' Tumor Study Group (NWTSG) has contributed to improving the clinical management and outcome of children affected by Wilms' Tumor. We have managed our patients according to NWTSG protocols and report our results herein.
Methods: Retrospective chart review of consecutive patients presenting at the Children's Hospital of Eastern Ontario (CHEO) with a diagnosis of Wilms' Tumor between April 1990 and March 2001.
Results: Forty patients with Wilms' Tumor (18 M/22 F) were diagnosed at CHEO during this interval. Mean… More >

Abstract Objectives: To provide context in oncology for the significance of the benefits and cost of combined androgen blockade (CAB) in the treatment of advanced prostate cancer.
Methods: Canadian drug costs for the survival benefit with CAB in advanced prostate cancer were compared with the costs of benefit with new treatments in advanced non-small-cell lung cancer (NSCLC), metastatic colorectal cancer, and metastatic breast cancer. Clinical toxicities were also compared.
Results: The survival benefit with CAB in advanced prostate cancer appears to be approximately 3 months. The survival benefit with the addition of vinorelbine to cisplatin for the treatment of… More >
