PI3K/AKT pathway genetic alterations and dysregulation of expression in bladder cancer.

Purpose: To examine the involvement of specific components of the PI3K/AKT pathway in urinary bladder cancer development.

Methods: Samples from 65 tumors and 13 normal bladder tissues were collected. Genomic DNA isolation from snap-frozen and paraffin-embedded laser-microdissected tissues was followed by Sanger sequencing, whereas total RNA was purified for use in RT-PCR analyses.

Report of the long-term efficacy of two cycles of adjuvant bleomycin/etoposide/cisplatin in patients with stage I testicular nonseminomatous germ-cell tumors (NSGCT): a risk adapted protocol of the Hellenic Cooperative Oncology Group.

Objectives: Stage I testicular nonseminomatous germ-cell tumors (NSGCT) are highly curable. Following orchidectomy surveillance, adjuvant chemotherapy and retroperitoneal lymph node dissection can be applied. Certain factors are used to select patients in high-risk for relapse.

Biweekly carboplatin/gemcitabine in patients with advanced urothelial cancer who are unfit for cisplatin-based chemotherapy: report of efficacy, quality of life and geriatric assessment.

Objective: We evaluated safety and efficacy of first-line gemcitabine/carboplatin in unfit-for-cisplatin patients with advanced urothelial carcinoma and the effect on the quality of life and functional status of elderly patients (aged >70).

Methods: Unfit patients had ECOG performance status (PS) > or =2, creatinine clearance <50 ml/min or comorbidities precluding cisplatin administration. Carboplatin at area under the curve of 2.

Biweekly doxorubicin/ketoconazole as second-line treatment in docetaxel-resistant, hormone-refractory prostate cancer.

Objectives: Docetaxel is an effective first-line treatment for hormone-refractory prostate cancer. Nevertheless, the prognosis subsequent to progression after first-line therapy is poor and no second-line treatment has been established.

Methods: A total of 34 patients with androgen-independent prostate cancer received doxorubicin, 30 mg/m(2), every 2 weeks and ketoconazole daily, 400 mg orally every 8 hours.

Prognostic and predictive factors in patients with androgen-independent prostate cancer treated with docetaxel and estramustine: a single institution experience.

Objectives: To investigate potential prognostic and predictive factors in patients with androgen-independent prostate cancer (AIPC) treated with docetaxel chemotherapy.

Methods: This analysis included 94 consecutive AIPC patients who were treated between March 2001 and May 2006 with biweekly docetaxel 45 mg/m(2) (day 2) and estramustine 140 mg three dimes daily (days 1-3).

Results: Prostate-specific antigen (PSA) responses were observed in 45 of 84 evaluable patients (53%), whereas objective responses were observed in 16 of 40 patients with measurable disease (40%).
