ONJ is a manageable and preventable condition. Our data confirm that the application of preventive measures can significantly reduce the incidence of ONJ in cancer patients receiving BPs therapy. Dental exams combined to the identification of patients at risk in cooperation with the Dental Team can improve outcomes and increase the number of ONJ-free patients.
4HPR, at 200 mg/d for 5 years, resulted in constant drug plasma levels and constant retinol level reduction. After treatment interruption, 4HPR plasma concentrations decreased at the limit of detectability at 6 months and baseline retinol plasma concentrations were recovered after 1 month.
BackgroundNumerical rating scales (NRS), and verbal rating scales (VRS) showed to be reliable and valid tools for subjective cancer pain measurement, but no one of them consistently proved to be superior to the other. Aim of the present study is to compare NRS and VRS performance in assessing breakthrough or episodic pain (BP-EP) exacerbations.MethodsIn a cross sectional multicentre study carried out on a sample of 240 advanced cancer patients with pain, background pain and BP-EP intensity in the last 24 hours were measured using both a 6-point VRS and a 0-10 NRS. In order to evaluate the reproducibility of the two scales, a subsample of 60 patients was randomly selected and the questionnaire was administered for a second time three to four hours later. The proportion of "inconsistent" (background pain intensity higher than or equal to peak pain intensity) evaluations was calculated to compare the two scales capability in discriminating between background and peak pain intensity and Cohen's K was calculated to compare their reproducibility.ResultsNRS revealed higher discriminatory capability than VRS in distinguishing between background and peak pain intensity with a lower proportion of patients giving inconsistent evaluations (14% vs. 25%). NRS also showed higher reproducibility when measuring pain exacerbations (Cohen's K of 0.86 for NRS vs. 0.53 for VRS) while the reproducibility of the two scales in evaluating background pain was similar (Cohen's K of 0.80 vs. 0.77).ConclusionsOur results suggest that, in the measurement of cancer pain exacerbations, patients use NRS more appropriately than VRS and as such NRS should be preferred to VRS in this patient's population.
Five hundred and thirty-nine patients with carcinoma of the breast treated with total axillary dissection and with positive axillary nodes were evaluated. The total number of lymph nodes removed was 11,082, with an average of 20.5 nodes per patient. The average number of lymph nodes at the first level was 13.8, at the second level 4.5, at the third level 2.2. The average number of nodes was 20.7 in cases treated with Halsted mastectomy, 20.9 with total mastectomy and axillary dissection, 20.3 with quadrantectomy and axillary dissection. Of 3259 metastatic nodes, 64 were site of micrometastases; 797 were partially involved, 441 were totally involved and 1957 were site of metastases with extracapsular invasion. In 314 (58.2%) the first level only was involved, in 117 cases (21.7%) metastases were present at the first and second level, whereas in 88 cases (16.3%) all the three levels were sites of metastases. Only 20 cases showed skipping distribution. In 1.5% of the cases the first level was skipped by metastases, in 0.4% the first nodes of the first level are clear the chances that metastatic nodes are present at the second and third levels are negligible. When the nodes at the first level are positive, the chances that metastases are also present at the higher levels are of the order of 40.0%.
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.
