Patient-Reported Outcomes of Patients With Advanced Biliary Tract Cancers Receiving Gemcitabine Plus Capecitabine: A Multicenter, Phase II Trial of the Swiss Group for Clinical Cancer Research

To evaluate the effects of palliative chemotherapy with gemcitabine plus capecitabine (GemCap) on patient-reported outcomes measured using clinical benefit response (CBR) and quality-of-life (QOL) measures in patients with advanced biliary tract cancer. Patients had to manifest symptoms of advanced biliary tract cancer and have at least one of the following: impaired Karnofsky performance score (60 to 80), average analgesic consumption >or= 10 mg of morphine equivalents per day, and average pain intensity score of >or= 20 mm out of 100 mm. Treatment consisted of oral capecitabine 650 mg/m(2) twice daily on days 1 through 14 plus gemcitabine 1,000 mg/m(2) as a 30-minute infusion on days 1 and 8 every 3 weeks until progression. The primary end point was the number of patients categorized as having a CBR or stable CBR (SCBR) during the first three treatment cycles. Forty-four patients were enrolled (bile duct cancer, n = 36; gallbladder cancers, n = 8). The main grade 3 or 4 adverse events included hematologic toxicity and fatigue. After three cycles, 36% of patients achieved a CBR, and 34% achieved an SCBR. Over the full course of treatment, 57% of patients achieved a CBR, and 18% achieved an SCBR. Improved QOL was observed in patients with a CBR or SCBR. The objective response rate was 25%. Median time to progression and overall survival times were 7.2 months and 13.2 months, respectively. Chemotherapy with GemCap is well tolerated and effective and leads to a high CBR rate. Patient-reported outcomes are useful for evaluating the effects of palliative chemotherapy in patients with biliary tract cancer.

The Impact of Perioperative Dexmedetomidine Infusion on Postoperative Narcotic Use and Duration of Stay after Laparoscopic Bariatric Surgery

Dexmedetomidine (Precedex, Hospira, Lake Forest, IL) is an alpha-2 receptor agonist with sedative and analgesic sparing properties. This medication has not been associated with respiratory suppression, despite occasionally high levels of sedation. For 10 months, all patients undergoing a laparoscopic bariatric procedure received a dexmedetomidine infusion 30 min before the anticipated completion of the procedure (n = 34). A control group was comprised of a similar number of patients to have had laparoscopic bariatric surgery in the time period immediately before these 10 months (n = 37). All pathways and discharge criteria were identical for patients in each group. A total of 73 patients were included in this retrospective chart review. Two gastric bypass patients were excluded for complications requiring additional surgery (one bleed and one leak). Gastric bypass patients who received a dexmedetomidine infusion required fewer narcotics (66 vs 130 mg of morphine equivalents) than control patients and met discharge criteria on post-op day (POD) 1 more often (61% discharged POD 1 vs 26% discharged POD 1, p = 0.02). Vital signs and pain scores were similar in all groups. Dexmedetomidine infusion perioperatively is safe and may help to minimize narcotic requirements and decrease duration of stay after laparoscopic bariatric procedures. This may have important patient safety ramifications in a patient population with a high prevalence of obstructive sleep apnea. A well-organized prospective, randomized, double-blinded trial is necessary to confirm the benefits of dexmedetomidine suggested by this study.

Valdecoxib for Postoperative Pain Management After Cesarean Delivery: A Randomized, Double-Blind, Placebo-Controlled Study

Although nonsteroidal antiinflammatory drugs (NSAIDs) improve postoperative pain relief after cesarean delivery, they carry potential side effects (e.g., bleeding). Perioperative cyclooxygenase (COX)-2 inhibitors show similar analgesic efficacy to nonsteroidal antiinflammatory drugs in many surgical models but have not been studied after cesarean delivery. We designed this randomized double-blind study to determine the analgesic efficacy and opioid-sparing effects of valdecoxib after cesarean delivery. Healthy patients undergoing elective cesarean delivery under spinal anesthesia were randomized to receive oral valdecoxib 20 mg or placebo every 12 h for 72 h postoperatively. As a result of cyclooxygenase-2 inhibitors safety concerns that became apparent during this study, the study was terminated early after evaluating 48 patients. We found no differences in total analgesic consumption between the valdecoxib and placebo groups (121 +/- 70 versus 143 +/- 77 morphine mg-equivalents, respectively; P = 0.26). Pain at rest and during activity were similar between the groups despite adequate post hoc power to have detected a clinically significant difference. There were also no differences in IV morphine requirements, time to first analgesic request, patient satisfaction, side effects, breast-feeding success, or functional activity. Postoperative pain was generally well controlled. Adding valdecoxib after cesarean delivery under spinal anesthesia with intrathecal morphine is not supported at this time.

Palifermin for Oral Mucositis after Intensive Therapy for Hematologic Cancers

Oral mucositis is a complication of intensive chemotherapy and radiotherapy with no effective treatment. We tested the ability of palifermin (recombinant human keratinocyte growth factor) to decrease oral mucosal injury induced by cytotoxic therapy. This double-blind study compared the effect of palifermin with that of a placebo on the development of oral mucositis in 212 patients with hematologic cancers; 106 patients received palifermin (60 microg per kilogram of body weight per day) and 106 received a placebo intravenously for three consecutive days immediately before the initiation of conditioning therapy (fractionated total-body irradiation plus high-dose chemotherapy) and after autologous hematopoietic stem-cell transplantation. Oral mucositis was evaluated daily for 28 days after transplantation. The incidence of oral mucositis of World Health Organization (WHO) grade 3 or 4 was 63 percent in the palifermin group and 98 percent in the placebo group (P<0.001). Among patients with this degree of mucositis, the median duration of mucositis was 6 days (range, 1 to 22) in the palifermin group and 9 days (range, 1 to 27) in the placebo group. Among all patients, regardless of the occurrence of mucositis, the median duration of oral mucositis of WHO grade 3 or 4 was 3 days (range, 0 to 22) in the palifermin group and 9 days (range, 0 to 27) in the placebo group (P<0.001). As compared with placebo, palifermin was associated with significant reductions in the incidence of grade 4 oral mucositis (20 percent vs. 62 percent, P<0.001), patient-reported soreness of the mouth and throat (area-under-the-curve score, 29.0 [range, 0 to 98] vs. 46.8 [range, 0 to 110]; P<0.001), the use of opioid analgesics (median, 212 mg of morphine equivalents [range, 0 to 9418] vs. 535 mg of morphine equivalents [range, 0 to 9418], P<0.001), and the incidence of use of total parenteral nutrition (31 percent vs. 55 percent, P<0.001). Adverse events, mainly rash, pruritus, erythema, mouth and tongue disorders, and taste alteration, were mild to moderate in severity and were transient. Palifermin reduced the duration and severity of oral mucositis after intensive chemotherapy and radiotherapy for hematologic cancers.

Laparoscopic radical cystectomy and ileal conduit reconstruction: preliminary experience.

We present our preliminary experience with laparoscopic radical cystoprostatectomy for muscle-invasive carcinoma of the urinary bladder. Patient and operative data and the surgical technique are presented. Laparoscopic radical cystoprostatectomy and bilateral pelvic lymph node dissection were performed using five or six ports by a transperitoneal approach. An ileal conduit urinary diversion was constructed at the site of specimen retrieval. The procedure was successful in nine of ten patients with a mean blood loss of 533 mL and an average transfusion of 1.3 units per patient. The mean operating time was 6.48 hours and an average of 33 mg of morphine equivalents was required for analgesia. The mean hospital stay was 10.8 days. One patient had surgical margins positive for cancer, while none had histologic evidence of pelvic nodal metastasis. There were five minor and major intraoperative and postoperative complications. The remaining patient, treated early in our experience, developed hypercarbia necessitating conversion to open surgery. No metastases have been seen after a mean duration of follow-up of 19 months. Laparoscopic radical cystoprostatectomy with open ileal conduit urinary diversion is a feasible alternative to traditional open radical cystectomy. Urinary diversion can be performed through the small incision necessary to extract the surgical (radical cystoprostatectomy) specimen from the abdomen. With our modified technique, it also is feasible to reduce the cost.

A microbiological survey of automated biochemical machines.

The potential microbial hazards to laboratory personnel from operating three pieces of automated laboratory equipment have been tested using challenges of bacteria in serum or water. Aerosols did not seem to be a hazard, and the recommended disinfection procedures seemed quite adequate, although 2% aqueous activated glutaraldehyde is to be preferred to hypochlorite. The use of plastic gloves for protecting hands when changing rinse cups and pH electrodes is recommended.
