    Notes: Abstract PURPOSE. Multiple attempts have been made to improve the clinical/pathologic staging system of Dukes to focus adjuvant therapy decisions. The purpose of this study was to determine whetherK-ras mutational status of regional nodes in patients with Dukes B2 colorectal cancer could be used to stage their disease more accurately. METHODS: Using formalin-fixed, paraffin-embedded archival material, tumor samples were screened forK-ras mutations using a mutation-specific polymerase chain reaction method, followed by gel electrophoresis in a 96-well array. Patients with Dukes B2 tumors that have mutations in codon 12 or 13 of theK-ras gene were identified. RESULTS: Mutational analysis of the lymph nodes from these patients revealed an 80 percent (16/20) incidence of the same mutations in regional lymph nodes. None of the four patients with mutation-free nodes developed recurrence compared with 37.5 percent (6/16) withK-ras positive lymph nodes. CONCLUSIONS: The data suggest that patients with Dukes B2 colorectal cancers that have mutations in codon 12 or 13 of theK-ras gene are at high risk for the development of nodal metastases. Mutational analysis of the lymph nodes identifies high-risk patients who should be considered for adjuvant chemotherapy. Therefore,K-ras mutational analysis should be considered for molecular staging of colorectal cancer.

    Notes: Abstract  This review provides a summary of the cost-effectiveness, clinical utility, performance, and interpretation of screening helical cervical spine CT for trauma patients. Recent evidence supports the use of helical CT as a cost-effective method for screening the cervical spine in high-risk trauma patients. Screening cervical spine CT can be performed at the time of head CT to lower the cost of the evaluation, and when all short- and long-term costs are considered, CT may actually save money when compared with traditional radiographic screening. In addition to having higher sensitivity and specificity for cervical spine injury, CT screening also allows more rapid radiological clearance of the cervical spine than radiography. Patients who are involved in high-energy trauma, who sustain head injury, or who have neurological deficits are candidates for CT screening. Screening with CT may enhance detection of other potentially important injuries of the cervical region.

    Notes: Abstract Purpose: To identify characteristics of female patients andof semen that were associated with live birth followingintra-uterine insemination (IUI). Methods: Retrospective review of medical and laboratoryresults from 533 women who underwent IUI with partner'ssperm from 1993 through 1995. Results: Among 1728 cycles, 116 (6.7%) resulted in livedeliveries. Among the 38 patient and semen variablesanalyzed, only 3 were associated with successful IUI outcome:female age 〈37.7 years at the time of treatment (P = 0.02);the absence of any corrective pelvic surgery (P 〈 0.001);and postwash sperm motility (P = 0.006). Couples withnone of these three risk factors achieved per-cycle pregnancyrates of 12.4%. Women with two risk factors (age and pelvicsurgery) achieved per-cycle pregnancy rates of 4.6% whensperm had good postwash motility. No pregnancies wereachieved when low postwash motility was combined withany other risk factor. Conclusions: Advanced female age, poor postwash spermmotility, and a history of corrective pelvic surgery aresignificant risk factors for poor IUI success rates. Poor postwashsperm motility in combination with either of these other tworisk factors resulted in no successful pregnancies.

    Effect of Clinical and Semen Characteristics on Efficacy of Ovulatory Stimulation in Patients Undergoing Intrauterine Insemination (2000)

    Notes: Abstract Purpose: We measured the effect of ovulatory stimulation(OS) upon intrauterine insemination (IUI) success rates,particularly among patients with risk factors for IUI failure. Methods: Retrospective review of medical and laboratoryresults from 512 patients who underwent 1576 cycles ofIUI with partner's sperm over a 3 year period. Data werecollected on 3 risk factors for IUI failure (advanced femaleage 〉37.7 years, prior corrective pelvic surgery, and poorpost-wash sperm motility), and on method of OS (none,clomiphene citrate, or gonadotropin). Results: Patients who underwent OS had significantly higherpregnancy rates (7.6;pc) than those who did not (4.7%, p =0.02). However, when patients were stratified by their riskfactors, OS made a significant difference only for patientswithout risk factors. These patients had a 15.5% per cyclepregnancy rate with OS, compared to 7.9% in unstimulatedIUI cycles (p = 0.04). Conclusions: Ovulatory stimulation doubles IUI pregnancyrates among young patients without a prior pelvic surgeryand with good post-wash semen quality. The benefit of OSfor patients with risk factors for IUI failure is unclear. Thesepatients should be counseled that their chances for successwith IUI are limited, with or without OS.

    Breeding to Increase the Concentration of 2-phenylethyl Glucosinolate in the Roots of Brassica napus (2000)

    Notes: Abstract Root concentrations of 2-phenylethyl glucosinolate in canola, Brassica napus, influence the susceptibility of the crop to the root lesion nematode (Pratylenchus neglectus), as well as the nematicidal effect of root tissues as they degrade in the soil. Plants containing high 2-phenylethyl glucosinolate should therefore reduce soil populations of P. neglectus. A selection program was developed to increase the proportion of total glucosinolates contributed by 2-phenylethyl glucosinolate in the roots of B. napus cv. Dunkeld. Variation within this accession was observed to be stable across the S1 and S2 generations. The segregation observed for 2-phenylethyl glucosinolate percentage suggested that the trait was encoded at a single locus, with the "high" phenotype being dominant. Plants with the high 2-phenylethyl glucosinolate phenotype (〉45% of total glucosinolates) were shown to be significantly more resistant to P. neglectus than otherwise identical "low" phenotypes (〈45% of total).

    Perception of quality of life by patients, partners and treating physicians (2000)

    Notes: Abstract The objective of the study was to determine possible differences in perception of quality of life (QoL) between patients with metastatic breast or prostate cancer, their partners, and the treating physician. Patients with metastatic breast cancer (n = 71), and metastatic prostate cancer (n = 29), a partner, and the physician each completed the same QoL questionnaire indicating how they perceived the patient's QoL. The European organization for research and treatment of cancer (EORTC) QLQ-C30 questionnaire was used to assess patients with breast cancer and the modified prostate cancer specific quality of life instrument (PROSQOLI) for patients with prostate cancer. There was reasonable agreement in mean scores between patients, and physicians or partners, for many domains of QoL; however, there was substantial discordance between scores when considering individual patients. For patients with metastatic breast cancer, physicians systematically underestimated overall QoL (p = 0.0002), social functioning (p = 0.001), and role functioning (p = 0.008), while partners showed better agreement. With prostate cancer physicians tended to underestimate pain, while mean scores for spouses were more concordant. There is substantial variability between ratings of QoL by physicians or partners, as compared to patient ratings. Medical decisions should be based on information about QoL provided by patients using validated methods.
