Purpose To determine, in a randomized comparison, whether the addition of paclitaxel to etoposide and cisplatin improves the time to progression and overall survival in patients with extensive small-cell lung cancer (SCLC) compared with standard etoposide and cisplatin and to compare the regimens' toxicity. Patients and Methods Eligible patients (N = 587) with untreated extensive SCLC were randomly assigned to receive either cisplatin 80 mg/m2 on day 1 and etoposide 80 mg/m2 on days 1 through 3 administered every 3 weeks for six cycles (EP) or cisplatin 80 mg/m2 on day 1, paclitaxel 175 mg/m2 over 4 hours on day 1, and etoposide 80 mg/m2 on days 1 to 3 followed by recombinant human granulocyte colony-stimulating factor on days 4 to 18 administered every 3 weeks for six cycles (PET). Results Reporting of demographics, response, and survival included 565 patients, of whom 282 were randomly assigned to receive EP and 283 were assigned to receive PET. Overall response rates were 68% for the EP arm and 75% for the PET arm. Median failure-free survival time was 5.9 months for the EP arm and 6 months for the PET arm (P = .179). Median overall survival time was 9.9 months for patients on EP and 10.6 months for patients on PET (P = .169). Toxic deaths occurred in 2.4% of the patients on EP and 6.5% of patients on PET. Conclusion PET did not improve the time to progression or survival in patients with extensive SCLC compared with EP alone and was associated with unacceptable toxicity.

ABSTRACT Exposure of ciprofloxacin- and cefepime-susceptible Pseudomonas aeruginosa isolates to increasing concentrations of ciprofloxacin selected for ciprofloxacin resistance in 26/27 and cefepime nonsusceptibility in 7/27 isolates. Exposure of the isolates to increasing concentrations of cefepime selected for cefepime nonsusceptibility in 20/27 isolates but not for ciprofloxacin resistance.

Purpose This study explored patients’ perceptions of barriers to diabetes education among a mostly African American population of adults with diabetes. Methods A survey was conducted among 605 new patients attending an urban outpatient diabetes clinic. The questionnaire gathered information on issues patients believed would adversely affect their ability to learn about diabetes. The type and frequency of education barriers were evaluated, and variables associated with reporting an obstacle were analyzed. Results Average patient age was 50 years, diabetes duration was 5.6 years, body mass index was 32 kg/m2, and hemoglobin A1C was 9.1%. The majority (56%) were women, 89% were African American, and 95% had type 2 diabetes. Most respondents (96%) had received some prior instruction in diabetes care; however, 53% anticipated future difficulties learning about diabetes. The most commonly cited concerns were poor vision (74%) and reading problems (29%). Patients with a perceived barrier to diabetes education were older (P < .001) than were persons without a barrier, and they differed in both employment and educational status (both P < .001). In adjusted analyses, older age, male gender, being disabled, and having an elementary education or less were associated with a significantly increased likelihood of having a barrier to diabetes education, whereas having a college education decreased the odds. Higher hemoglobin A1C levels also tended to be associated with a greater chance of reporting an education barrier (P = .05). Conclusions A substantial number of persons anticipated a barrier to diabetes education. Interventions at multiple levels that address the demographic and socioeconomic obstacles to diabetes education are needed to ensure successful self-management training.

Purpose To prospectively assess the impact of treatment with cisplatin alone or in combination with topotecan (CT) on quality of life (QOL) in patients with advanced or recurrent cervical cancer, and to explore the prognostic value of baseline QOL scores. Patients and Methods Patients entered on Gynecologic Oncology Group (GOG) Protocol 179 were expected to complete QOL assessments at four time points using Functional Assessment of Cancer Therapy–General (FACT-G), Cervix subscale (Cx subscale), FACT/GOG–Neurotoxicity subscale (NTX subscale), Brief Pain Inventory (BPI), and UNISCALE (UNI). Adjusting for patient age, baseline scores, and effects of time, we longitudinally examined treatment effect on QOL during and after chemotherapy. Results Among patients randomly allocated to receive cisplatin (n = 146) or CT (n = 147), there were no statistically significant differences in QOL up to 9 months after randomization despite more hematologic toxicity in the combination arm. QOL assessments were completed at rates of 98%, 85%, 68%, and 59%, respectively, for the four time points, with similar rates and reasons for nonparticipation between regimens. Baseline FACT-G (P = .0016) and BPI (P = .0001) scores were significantly associated with patient age; older patients had better QOL and less pain. Baseline UNI was positively correlated with FACT-G (r = 0.66; P < .001) and Cx subscale (r = 0.29; P < .001), and negatively related to BPI (r = −0.41; P < .0001). Baseline FACT-Cx (FACT-G + Cx subscale) was associated with survival. Conclusion Despite increased toxicity, CT did not significantly reduce patient QOL when compared with cisplatin alone. Patient-reported QOL measures may be an important prognostic tool in advanced cervix cancer.

Purpose On the basis of reported activity of methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) or topotecan plus cisplatin in advanced cervix cancer, we undertook a randomized trial comparing these combinations versus cisplatin alone, to determine whether survival is improved with either combination compared with cisplatin alone, and to compare toxicities and quality of life (QOL) among the regimens. Patients and Methods Eligible patients were randomly allocated to receive cisplatin 50 mg/m2 every 3 weeks (CPT); cisplatin 50 mg/m2 day 1 plus topotecan 0.75 mg/m2 days 1 to 3 every 3 weeks (CT); or methotrexate 30 mg/m2 days 1, 15, and 22, vinblastine 3 mg/m2 days 2, 15, and 22, doxorubicin 30 mg/m2 day 2, and cisplatin 70 mg/m2 day 2 every 4 weeks (MVAC). Survival was the primary end point; response rate and progression-free survival (PFS) were secondary end points. QOL data are reported separately. Results The MVAC arm was closed by the Data Safety Monitoring Board after four treatment-related deaths occurred among 63 patients, and is not included in this analysis. Two hundred ninety-four patients enrolled onto the remaining regimens: 146 to CPT and 147 to CT. Grade 3 to 4 hematologic toxicity was more common with CT. Patients receiving CT had statistically superior outcomes to those receiving CPT, with median overall survival of 9.4 and 6.5 months (P = .017), median PFS of 4.6 and 2.9 months (P = .014), and response rates of 27% and 13%, respectively. Conclusion This is the first randomized phase III trial to demonstrate a survival advantage for combination chemotherapy over cisplatin alone in advanced cervix cancer.
