Factors associated with locoregional recurrence in penile cancer: a case-control study.

Purpose: Surgical excision of the primary tumor in penile cancer (PC) has shown good local control with a risk of locoregional recurrence (LR) of 4-8%. The magnitude of such risk and the characteristics that distinguish patients who develop LR from those who do not is controversial. Our goal was to estimate, clinical and oncological characteristics, and outcome of LR in a cohort of patients with PC.

[Primary testicular rhabdomyosarcoma: A case report].

Background: Rhabdomyosarcoma is the most common sarcoma of soft tissues in childhood and adolescence, with an annual incidence of 4-7 cases per million children aged 15. Embryonal rhabdomyosarcoma is common in adults younger than 30 years, and are usually presented as a large painless, palpable mass (> 5cm). Survival in the case of paratesticular sarcoma in men is approximately 50%.

[Experience in nephron-sparing surgery in patients with small renal tumors].

Background: Nephron -sparing surgery is currently the treatment of choice for surgical removal of solid renal tumours smaller than 7 cm, in the case of a solitary kidney, bilateral renal tumours or the presence of chronic renal failure.

Material And Methods: An observational, descriptive, retrospective and cross-sectional study was conducted. The variables evaluated were: age at diagnosis, gender, intraoperative blood loss, operative time, preoperative tumour size, hospital stay, pathology report, pTNM classification, Fuhrman nuclear grade, pre- and post-operative creatinine, monitoring for cancer.
