RESUMO

OBJECTIVE: Transvaginal sonography (TVS) and serum biomarkers are used widely in clinical practice to triage women with adnexal masses, but the effectiveness of current biomarkers is weak. The aim of this study was to determine the best method of diagnosing patients with adnexal masses, in terms of diagnostic accuracy and economic costs, among four triage strategies: (1) the International Ovarian Tumor Analysis group's simple rules (SR) for interpretation of TVS with subjective assessment (SA) by an experienced ultrasound operator when TVS results are inconclusive (referred to hereafter as SR ± SA), (2) SR ± SA and cancer antigen 125 (CA 125), (3) SR ± SA and human epididymis protein 4 (HE4) and (4) SR ± SA and the risk of malignancy algorithm (ROMA). Our main hypothesis was that the addition of the biomarkers to SR ± SA could improve triaging of these patients in terms of diagnostic accuracy (i.e. malignant vs benign). As secondary analyses, we estimated the cost effectiveness of the four strategies and the diagnostic accuracy of SR ± SA at the study hospitals. METHODS: Between February 2013 and January 2015, 447 consecutive patients who were scheduled for surgery for an adnexal mass at the S. Anna and Mauriziano Hospitals in Turin were enrolled in this multicenter prospective cohort study. Preoperative TVS was performed and preoperative CA 125 and HE4 levels were measured. Pathology reports were used to assess the diagnostic accuracy of the four triage strategies and the cost of each strategy was calculated. RESULTS: A total of 391 patients were included in the analysis: 57% (n = 221) were premenopausal and 43% (n = 170) were postmenopausal. The overall prevalence of malignancy was 21%. SR were conclusive in 89% of patients and thus did not require SA; the overall performance of SR ± SA showed a sensitivity of 82%, specificity of 92% and positive and negative predictive values and positive and negative likelihood ratios of 74%, 95%, 10.5 and 0.19, respectively. In premenopausal women, mean cost among the four triage strategies varied from €36.41 for SR ± SA to €70.12 for SR ± SA + ROMA. The addition of biomarkers to SR ± SA showed no diagnostic advantage compared with SR ± SA alone and was more costly. Among postmenopausal women, mean cost among the four triage strategies varied from €39.52 for SR ± SA to €73.23 for SR ± SA + ROMA. Among these women, SR ± SA + CA 125 and SR ± SA + ROMA had a higher sensitivity (both 92% (95% CI, 85-99%)) than SR ± SA (81% (95% CI, 71-91%)), but SR ± SA had a higher specificity (84% (95% CI, 77-91%)). SR ± SA + CA 125 and SR ± SA + ROMA improved diagnostic accuracy, each diagnosing a third more malignant adnexal masses. In postmenopausal women, compared with SR ± SA alone, SR ± SA + CA 125 showed a net reclassification improvement (NRI) of 28.8% at an extra cost of €13.00, while the extra cost for SR ± SA + ROMA was €33.71, with a comparable gain, in terms of NRI, as that of SR ± SA + CA 125. CONCLUSIONS: In our study sample, SR ± SA seems to be the best strategy to triage women with adnexal masses for surgical management. Among postmenopausal women, SR ± SA + CA 125 increased the NRI at a reasonable extra cost. Our data do not justify the use of HE4 and ROMA in the initial triage of women with adnexal masses.

RESUMO

BACKGROUND: In literature the reliability of reticulocyte hemoglobin content (CHr) has been recently emphasized to detect "functional" iron deficiency induced by erythropoietin therapy. METHODS: In the present work the behavior of CHr in 68 uremic patients hemodialysis has been evaluated. RESULTS: Its values appeared poorly correlated (R2 = 0.32) to the hypochromic erythrocyte percent values, and furthermore CHr sensitivity seemed poor, with pathologic low values detected in three cases only, all characterized by reduced mean corpuscular volume (MCV). CONCLUSIONS: In the cases personally observed, MCV and CHr are weakly correlated (R2 = 0.15); reticulocyte hemoglobin absolute value in personal opinion does not appear as a reliable index of iron deficiency, being rather dependent on reticulocyte volume.

RESUMO

In this study, 30 patients with metastatic breast cancer were treated with 5-Fluorouracil (5-FU) and high-dose Folinic acid, using a new sequential dosing schedule. Our treatment consisted of one day i.v. infusion of 500 mg/m2 of Folinic acid over two hours. One hour after the beginning of Folinic acid infusion, 5-FU (500 mg/m2) was given by i.v. bolus injection. The complete and partial response rates achieved (CR+PR) were 21% in a population of patients pretreated with chemotherapy including 5-FU. Cutaneous and bone metastasis responded best to our treatment. There were no treatment related deaths or withdrawals from the study. The drug related toxicities observed in this study were usually mild to moderate and easily controllable. Thus preliminary results of our study suggest that response rate, quality of life and time to disease progression for the responders improved by this sequential treatment.
