RESUMEN

PURPOSE: To assess safety and efficacy of folinic acid, 5-fluorouracil, gemcitabine (FFG) and folinic acid, fluorouracil, oxaliplatin (FOLFOX4) regimens with added bevacizumab as first-line treatment in patients with advanced colorectal cancer (CRC). PATIENTS AND METHODS: Patients with Stage III unresectable or Stage IV adenocarcinoma of the colon or rectum were randomly assigned to either FFG weekly for 6 weeks of an 8-week cycle or FOLFOX4 every 2 weeks. After FDA approval, bevacizumab 5 mg/kg was added every 2 weeks. Treatment continued until disease progression. Planned enrollment was 190 patients. Primary endpoint was overall response rate (ORR); secondary endpoints included evaluation of adverse events, time to progression (TTP), and overall survival (OS). Disease Control Rate (DCR; % of patients with complete or partial responses or stable disease) was a post hoc analysis. RESULTS: The trial was stopped prematurely due to low enrollment. Of 84 enrolled patients (42 to each arm), 36 patients (18 in each arm) received bevacizumab. ORR was greater (P = .002) for FOLFOX4 (17/42; 40.5%) than for FFG (4/42; 9.5%); however, TTP, OS, and DCR results were not statistically different comparing FOLFOX4 and FFG. Peripheral neuropathy was more frequent (P = <.001) with FOLFOX4 (18/42; 42.9%) than with FFG (1/42; 2.4%). CONCLUSIONS: FFG and FOLFOX4 were generally well tolerated. Based on ORR, FOLFOX4 was superior to FFG. However, differences in TTP and OS comparing regimens were inconclusive. General use of gemcitabine as a biomodulator of 5-fluorouracil in CRC cannot be recommended at this time and the regimen remains investigational.

RESUMEN

PURPOSE: To evaluate the effect of performance and outcomes feedback on adherence to clinical practice guidelines regarding chemotherapy-induced nausea and emesis (CINE). METHODS: Institutional CINE clinical practice guidelines were developed based on American Society of Clinical Oncology guidelines. Consecutive administrations of moderately/highly emetogenic chemotherapy were assessed for errors. Baseline statistical process control (SPC) charts were created and mean errors per administration were calculated. Prospective SPC charts were used to measure the effect of guideline development and distribution, a visiting lecturer, and ongoing feedback regarding compliance with guidelines employing SPC charts. Patients were surveyed regarding the extent and severity of CINE for 5 days postadministration. These outcomes were then shared with physicians. RESULTS: Baseline compliance was poor (mean, 0.87 omissions per chemotherapy administration), largely because of inadequate adherence to recommendations for delayed CINE management. Most patients experienced delayed nausea, particularly on day 3 postchemotherapy. Physician prescribing performance did not undergo sustained improvement despite guideline development or distribution, a lecture by a visiting expert, or sharing of adherence data with clinicians. Once patient outcomes were shared, physicians accepted the need for compliance and instituted nurse practitioner antiemetic prescribing, with almost complete compliance and concurrent measurable reduction in day 3 nausea. SPC charts documented improvements in both outcomes. CONCLUSIONS: SPC charts effectively monitor ongoing compliance and patient symptoms and represent appropriate outcome measurement and change facilitation tools. However, physician participation in guideline development and evidence of poor compliance alone did not improve prescribing performance. Only evidence of patient CINE experience coupled with noncompliance improved results.

RESUMEN

BACKGROUND: While many cancer patients derive strength from spiritual or religious faith, concern often remains regarding how different patient subgroups and other community members might react to faith-based services when sponsored by a secular health care organization. METHODS: "A Sacred Gathering for Those Touched by Cancer" was presented in 2 Catholic and 2 Protestant churches. The service included key themes (surrendering fear, peace, hope, community support, and God's love) reinforced by Scripture, music, ritual, and prayer. Patients, clergy, and staff participated. Questionnaires evaluating attendee characteristics, emotional response to the service, and satisfaction with service components were distributed. RESULTS: Attendees (women: 80%; Catholic: 71%; half older than 50 years) returned 450 questionnaires. Most found the service very (83%) or somewhat (14%) helpful. Multivariate regression of perceptions indicated (1) the opinion that the service was helpful was associated with the perception that the service made the respondent feel hopeful (P < .0001), that respondents found inspirational messages important (P = .058), and that the respondent was a current patient (P = .018) and (2) an angry response reported by respondents was associated with current patient status (P = .0044). Men tended to feel less loved by God (P = .012) and people (P = .034) and less hopeful (P = .057) than women did. Men liked music less (P = .048), liked Scripture and prayers concerning community less (P = .040), and found prayer (P = .0035) less important. However, men felt the gatherings were as helpful as women did. Past patients felt less sadness than did others (P = .0084). Increased perceived helpfulness of the service was associated in a multivariate analysis with current patient status, feeling hopeful as a result of the service, increased appreciation of the service's inspirational message, and the perception that the service was not too long. CONCLUSIONS: While almost all attendees found the service somewhat or very helpful, distinct preferences and reactions to the service were noted for gender, patient status, and religious affiliation. This evaluation will help tailor future events to better meet the spiritual needs of cancer patients and their loved ones.
