These preliminary findings are promising. A larger sample, however, would be required in order to determine a more precise SUVmax reduction cut-off threshold during induction. Other methods for determining metabolic volume thresholds will be investigated. If functional imaging proves contributive, it could enable early screening of non-responders, avoiding unnecessary intoxication.
Background Most recent trials evaluating extensive screening strategies for occult cancer in patients with unprovoked venous thromboembolism have failed, because, among other reasons, of an overall low rate of occult cancer. The RIETE investigators recently proposed a score aimed at identifying a subgroup at higher risk. Methods We retrospectively computed the RIETE score for all patients included in the MVTEP study, which evaluated the accuracy of [¹⁸F]fluorodeoxyglucose-positron emission tomography in the screening of occult cancer in patients with unprovoked venous thromboembolism. Performance of the RIETE score was assessed according to the proportion of patients classified in each risk group, and the corresponding rates of cancer diagnosis. Results Among the 386 patients included in the analysis, 136 patients (35.3%) were classified as high risk by the RIETE score. Cancer was diagnosed in 16 (11.8%) of them, whereas it was diagnosed in nine (3.6%) of the 250 patients with a low RIETE cancer score: odds ratio of 3.6 (95% confidence interval [CI] 1.53-8.32). The area under the receiver operating characteristic curve was 0.63 (95% CI 0.51-0.74). Conclusion The RIETE score seems to be able to identify a subgroup at high risk for cancer (10%) in our specific dataset of patients with unprovoked venous thromboembolism.
<b><i>Objectives:</i></b> The aim of this study was to identify and compare prognostic factors, management strategies, and outcomes of very locally advanced cervical cancer (CC) (i.e., stage IVA) and metastatic CC (i.e., stage IVB). <b><i>Method:</i></b> A retrospective review was conducted based on all consecutive patients treated<b><i></i></b>for stage IV CC in a comprehensive cancer care centre between 2004 and 2017. <b><i>Results:</i></b> Sixty-eight patients were included. Performance status (PS) was ≥2 for 35.9%. Median age at diagnosis was 60.5. There were 24 stage IVA CC (35.3%) and 44 stage IVB CC (64.7%). Seventeen patients with stage IVB CC had only para-aortic lymph node metastases (38.6%), 13 had only distant metastases (29.5%), and 14 had both (31.8%). Patients with stage IVA CC experienced a radiotherapy with curative intent (<i>n</i> = 14, 58.3%) +/– concomitant chemotherapy, or a palliative treatment (<i>n</i> = 10, 41.7%). Twenty-three patients with stage IVB CC received a prior chemotherapy (52.3%), 11 a primary concomitant chemoradiation (25%), and 10 a palliative treatment (22.7%). The mean follow-up was 18.0 months. The 5-year overall survival was 5.1% for stage IVA (95% CI = 0.7–33.9), and 10.5% for stage IVB (95% CI = 3.7–29.7). In multivariate analysis, PS >1 was identified as a poor prognostic factor of disease-specific survival for stage IVA CC. PS >1 and pelvic lymph node involvement were identified as poor prognostic factors of overall survival and disease-specific survival for stage IVB CC. <b><i>Conclusions:</i></b> In daily clinical practice, outcomes of stages IV CC are poor. Treatment of advanced and metastatic CC remains challenging. New management strategies are needed, as well as efficient preventive strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
