Most patients find a single OTFC dosage that adequately treats breakthrough pain. The optimal dose is found by titration and is not predicted by around-the-clock dose of opioids.

One hundred thirty‐nine patients receiving outpatient chemotherapy kept diaries of nonmedical expenses resulting from their disease and its treatment. Diaries were kept for both treatment and nontreatment weeks. Results showed that the mean cost to patients and their families for treatment weeks was $72.81, and for nontreatment weeks it was $45.88. Approximately 45% of these costs were out‐of‐pocket expenses, and 55% were wages lost. Transportation and food were the largest out‐of‐pocket expenses. Patients living at greater distance from treatment had higher out‐of‐pocket costs, and younger patients reported more wages lost. Fourteen percent of the patients were estimated to be spending more than 50% of their weekly incomes on nonmedical expenses, and these patients were found largely in the lower‐income categories. A method is proposed for using these data to estimate total nonmedical expenses for different treatment regimens, and also for estimating cancer patients' total nonmedical costs nationally.

This open-label study evaluated the long-term safety and tolerability of oral transmucosal fentanyl citrate (OTFC) in ambulatory cancer patients with breakthrough pain undergoing cancer care at 32 university- or community-based practices. Patients had participated in a previous short-term titration trial of OTFC, were experiencing at least one episode per day of breakthrough pain, and had achieved relief of their breakthrough pain with an opioid. Patients received OTFC units at a starting dosage strength determined in the short-term trial (200-1600 microg). Outcome measures included number of successfully treated breakthrough pains, global satisfaction rating (0 = poor through 4 = excellent), and side effects. In total, 41,766 units of OTFC were used to treat 38,595 episodes of breakthrough pain in 155 patients. Number of treatment days ranged from 1 to 423 (mean, 91 days). Patients averaged 2.9 breakthrough pain episodes per day. About 92% of episodes were successfully treated with OTFC and there was no trend toward decreased effectiveness over time. Most patients (61%) did not require dose escalation during treatment. Global satisfaction ratings were consistently above 3, indicating very good to excellent relief. Common adverse events associated with OTFC were somnolence (9%), constipation (8%), nausea (8%), dizziness (8%), and vomiting (5%). Six patients (4%) discontinued therapy due to an OTFC-related adverse event. There were no reports of abuse and no concerns about the safety of the drug raised by patients or families. OTFC was used safely and effectively during long-term treatment of breakthrough pain in cancer patients at home.

We conducted a randomized clinical trial in men with stage D2 prostate cancer to test whether androgen priming potentiates the efficacy of cytotoxic chemotherapy. Eighty-five men with progressive prostate cancer refractory to orchiectomy were treated continuously with aminoglutethimide and hydrocortisone to lower adrenal androgen secretion and were administered cyclic intravenous (IV) chemotherapy. The patients were randomized to receive either androgen priming or no additional treatment for three days before and on the day of chemotherapy. Median duration of follow-up was 43 months. Response rate (remission plus disease stabilization) was not significantly different between the stimulation and control arm when the analysis was restricted to evaluable patients (79% v 73%, respectively) or when it was extended to all patients (46% v 61%). Median duration of response was similar for the stimulation and control arm (9 and 10 months, respectively). Median survival was 10 months in the stimulation and 15 months in the control group (P = .0047). The androgen sensitivity of the tumors was supported by the greater toxicity in the stimulation arm associated with androgen administration. Factors found to be independently associated with improved clinical outcome included a high Karnofsky score and hematocrit, long duration of response to the initial castration, and normalization of an elevated serum acid phosphatase on treatment. We conclude that in this group of patients with advanced disease, androgen priming does not potentiate the efficacy of chemotherapy and is actually associated with a worse outcome. Furthermore, our data emphasize the heterogeneity of biologic behavior of prostate cancer.
