Salvage cryotherapy: is there a role for focal therapy?

Prostate cancer treatment has undergone vast development over the last few decades, but the most notable changes have included nerve-sparing open radical prostatectomy, laparoscopic radical prostatectomy, including robot-assisted and, more recently, cryotherapy and high-intensity focused ultrasound (HIFU). While radical surgery is the current gold standard, the less invasive therapeutic options of cryotherapy and HIFU are regarded as largely experimental by governing bodies. In the case of cryotherapy, a wealth of experience has been accumulated demonstrating its efficacy.

Cryotherapy for the prostate: an in vitro and clinical study of two new developments; advanced cryoneedles and a temperature monitoring system.

Objectives: To assess the characteristics of two new developments in cryotherapy for the prostate, IceRods (Oncura, Amersham, UK; 17 G cryoneedles with an advanced heat exchanger which produces a precise ice-ball comparable in size to those with larger diameter cryoneedles) and the Multitemp 1601 temperature monitoring system (TMS, InvivoSense, Trondheim, Norway) probes, in an in vitro model and in a clinical setting, to assess their usefulness, focusing in particular on the TMS probes.

Patients, Materials And Methods: We assessed the temperature profile and performance of the IceRods in several different configurations, in conjunction with the TMS probes for temperature mapping, in a phantom prostate model. Subsequently 20 patients with prostate cancer were treated with cryosurgery either as a primary or secondary treatment for radiation failure; all had a standard treatment protocol.

Twenty-three years of disease-free survival following cutaneous metastasis from a primary bladder transitional cell carcinoma.

We present a case of cutaneous metastases from a primary bladder transitional cell carcinoma (TCC), with a prolonged survival of 23 years. Cutaneous metastases from primary bladder TCC are uncommon and, like all metastases, have a poor prognosis. The common modality of treatment of cutaneous metastases from a primary bladder cancer is wide local excision of the metastases followed by combination chemotherapy.

Adenovirus-mediated expression of a soluble fibroblast growth factor receptor inhibits in vitro growth of prostate DU145 cells.

Background: Fibroblast growth factor (FGF) family plays a key role in prostate cancer. The soluble FGF receptor (sFGFR) has been studied with regards to inhibiting cancer growth and was shown to have a dominant negative effect on cellular signaling and function. Using replication deficient adenovirus-mediated gene transfer, we tested if sFGFR expression may have a suppressive effect on in vitro growth of prostate cancer cells.
