RESUMO

BACKGROUND: The original triple test score (TTS)--clinical examination, mammogram, and fine-needle aspiration (FNA) biopsy--has long been used to evaluate palpable breast masses. We modified the original TTS to include ultrasound (US) and core biopsy to determine their role in evaluating palpable breast masses. METHODS: A retrospective chart review of 320 female patients was performed. We developed a modified triple test score (mTTS) that included physical examination, mammogram and/or US, and FNA and/or core biopsy. For the examination and imaging score, 1-3 points were given for low, moderate, or high suspicion. Biopsy scores were characterized as benign, atypical, or malignant. Final outcome was determined by open biopsy or follow-up greater than 1 year. RESULTS: Physical examination was 92% accurate (95% confidence interval [CI] 0.89-0.96, p < 0.0001) at predicting whether a mass was benign or malignant. Imaging was 88% accurate (95% CI 0.84-0.92, p < 0.0001) and needle biopsy was 95% accurate (95% CI 0.92-0.98, p < 0.0001). The modified triple test was 99% accurate (95% CI 0.98-1.00, p < 0.0001). Each 1-point increment in the mTTS was associated with an increased risk of cancer, with an odds ratio of 9.73 (CI 5.16-18.4, p < 0.0001). For 150 patients, we compared the original TTS with the mTTS. US and core biopsy changed the scores of 24 patients; only three changed clinical management. CONCLUSIONS: For patients with a palpable breast mass and a mTTS score of 3-4, no further assessment is necessary. Those with a mTTS of 8-9 can proceed to definitive therapy. Patients with a mTTS of 5-7 require further assessment. US and/or core biopsy added little to the accuracy or predictive value of the original TTS.

RESUMO

The Breast Imaging Reporting and Data System (BI-RADS) lexicon for ultrasonography (US) is based on the established lexicon used successfully in mammography and attempts to provide a common language to avoid ambiguity in interpreting, reporting, and teaching breast US. Proper and consistent use of the BI-RADS US lexicon has numerous advantages, including facilitating (a) communication of final assessment categories that clearly indicate management recommendations, (b) data tracking for self-audits, and (c) clinical review of outcome summaries. However, the literature to date does not include sufficient data on outcomes to validate clinical use of the BI-RADS US lexicon. In this article, a pictorial review of the BI-RADS US lexicon descriptors is provided, and specific cases from a retrospective review are used to highlight the challenges in using the BI-RADS US lexicon. With these examples, suggestions are offered for greater clarity in the use of this lexicon. The technical challenges in follow-up US imaging are described. The challenges in assigning final assessment categories are detailed, as well as the clinical factors that may influence decision making and the management of certain lesions.

RESUMO

Magnetic resonance imaging is the current imaging modality of choice in the evaluation of patients presenting with myelopathic symptoms in the search for spinal cord lesions. It is important for the radiologist to recognize and differentiate nonneoplastic from the neoplastic process of the spinal cord as the differentiation of the 2 entities is extremely crucial to the neurosurgeon. This article presents a broad spectrum of benign intramedullary spinal abnormalities including syrinx, contusion, abscess, infarction, myelitis, multiple sclerosis, sarcoid, cavernoma, and arteriovenous malformation. Rare intramedullary neoplasms including dermoid tumor, astrocytoma, ependymoma, hemangioblastoma, lymphoma, ganglioneuroblastoma, and metastases are also illustrated. The clinical presentation and magnetic resonance signal characteristics as well as the differential diagnosis of the intramedullary lesions are discussed. The potential pitfalls in the differentiation of tumors from nonneoplastic disease of the spinal cord are also elucidated.

RESUMO

OBJECTIVE: To determine whether sonography can be used to categorize some solid breast masses as probably benign so that biopsy can be deferred. METHODS: We prospectively characterized 844 sonographically visible solid breast masses referred for biopsy. Mammographic and sonographic features of the masses were recorded, and all masses were categorized by American College of Radiology Breast Imaging Reporting and Data System classification before biopsy. Of the 844 masses, 148 were categorized as probably benign (Breast Imaging Reporting and Data System category 3). Sonographically guided biopsy (n = 804) or fine-needle aspiration (n = 40) was performed for pathologic correlation. RESULTS: Of the 148 masses that met the sonographic criteria for probably benign masses, there was 1 malignancy, for a negative predictive value of 99.3%. CONCLUSIONS: Follow-up can be an acceptable alternative to biopsy for sonographically probably benign solid masses.

RESUMO

Our goal was to further define the role of LPL gene polymorphisms in coronary heart disease (CHD) risk. We determined the frequencies of three LPL polymorphisms (D9N, N291S, and S447X) in 899 men from the Veterans Affairs HDL Intervention Trial (VA-HIT), a study that examined the potential benefits of increasing HDL with gemfibrozil in men with established CHD and low high density lipoprotein cholesterol (HDL-C; < or =40 mg/dl), and compared them with those of men without CHD from the Framingham Offspring Study (FOS). In VA-HIT, genotype frequencies for LPL D9N, N291S, and S447X were 5.3, 4.5, and 13.0%, respectively. These values differed from those for men in FOS having an HDL-C of >40, who had corresponding values of 3.2% (P = 0.06), 1.5% (P < 0.01), and 18.2% (P < 0.01). On gemfibrozil, carriers of the LPL N9 allele in VA-HIT had lower levels of large LDL (-32%; P < 0.01) but higher levels of small, dense LDL (+59%; P < 0.003) than did noncarriers. Consequently, mean LDL particle diameter was smaller in LPL N9 carriers than in noncarriers (20.14 +/- 0.87 vs. 20.63 +/- 0.80 nm; P < 0.003). In men with low HDL-C and CHD: 1) the LPL N9 and S291 alleles are more frequent than in CHD-free men with normal HDL-C, whereas the X447 allele is less frequent, and 2) the LPL N9 allele is associated with the LDL subclass response to gemfibrozil.
