BACKGROUND To determine the safety and maximum-tolerated dose of concurrent sunitinib and image-guided radiotherapy (IGRT) followed by maintenance sunitinib in oligometastastic patients. METHODS: Eligible patients had 1 to 5 sites of metastatic cancer measuring ≤6 cm. The most common treatment sites were bone, liver, and lung. Patients were treated with concurrent sunitinib (Day 1 through Day 28) and IGRT (40-50 Gy in 10 fractions starting on Day 8) followed by maintenance sunitinib (50 mg daily, 4 weeks on/2 weeks off starting on Day 43). The starting dose was sunitinib 25 mg and IGRT 40 Gy. Doses were escalated in a ping-pong design with incremental increases in either sunitinib or IGRT. RESULTS: Twenty-one patients with 36 metastatic lesions were enrolled, with a median follow-up of 10 months. No dose limiting toxicities (DLT) were noted at dose levels 1 or 2 (SU 37.5 mg/RT 40 Gy). One of 10 patients at dose level 3 (SU 37.5 mg/RT 50 Gy) and 2 of 5 patients at dose level 4 (SU 50 mg/RT 50 Gy) experienced DLTs comprising grade 4 myelosuppression and grade 3 nausea. At last follow-up, 8 patients are alive without evidence of progression. The 1-year local, progression-free, and overall survival were 85%, 44%, and 75%, respectively. CONCLUSIONS: Addition of SU (25 to 37.5 mg) to IGRT is tolerable in patients with oligome-tastases, without potentiation of RT toxicity. On the basis of promising antitumor responses observed with this novel combination, a multi-institutional phase 2 trial using SU 37.5 mg/RT 50 Gy is ongoing.

BackgroundProstate cancer is the most common cancer affecting men in the United States. Management options for localized disease exist, yet an evidence-based criterion standard for treatment still has to emerge. Although 5-year survival rates approach 98%, all treatment options carry the possibility for significant side effects, such as erectile dysfunction and urinary incontinence. It is therefore recommended that patients be actively involved in the treatment decision process. We have developed an Internet/CD-ROM-based multimedia Prostate Interactive Educational System (PIES) to enhance patients’ treatment decision making. PIES virtually mirrors a health center to provide patients with information about prostate cancer and its treatment through an intuitive interface, using videos, animations, graphics, and texts.Objectives(1) To examine the acceptability and feasibility of the PIES intervention and to report preliminary outcomes of the program in a pilot trial among patients with a new prostate cancer diagnosis, and (2) to explore the potential impact of tailoring PIES treatment information to participants’ information-seeking styles on study outcomes.MethodsParticipants (n = 72) were patients with newly diagnosed localized prostate cancer who had not made a treatment decision. Patients were randomly assigned to 3 experimental conditions: (1) control condition (providing information through standard National Cancer Institute brochures; 26%), and PIES (2) with tailoring (43%) and (3) without tailoring to a patient’s information-seeking style (31%). Questionnaires were administrated before (t1) and immediately after the intervention (t2). Measurements include evaluation and acceptability of the PIES intervention, monitoring/blunting information-seeking style, psychological distress, and decision-related variables (eg, decisional confidence, feeling informed about prostate cancer and treatment, and treatment preference).ResultsThe PIES program was well accepted by patients and did not interfere with the clinical routine. About 79% of eligible patients (72/91) completed the pre- and post-PIES intervention assessments. Patients in the PIES groups compared with those in the control condition were significantly more likely to report higher levels of confidence in their treatment choices, higher levels of helpfulness of the information they received in making a treatment decision, and that the information they received was emotionally reassuring. Patients in the PIES groups compared with those in the control condition were significantly less likely to need more information about treatment options, were less anxious about their treatment choices, and thought the information they received was clear (P < .05). Tailoring PIES information to information-seeking style was not related to decision-making variables.ConclusionsThis pilot study confirms that the implementation of PIES within a clinical practice is feasible and acceptable to patients with a recent diagnosis of prostate cancer. PIES improved key decision-making pr...
