A Comparative Study between the Preoperative Diagnostic Tumor Size and the Postoperative Pathologic Tumor Size in Patients with Breast Tumors

Purpose: This comparative study analyzed the relationship between the preoperative diagnostic tumor size and the postoperative pathologic tumor size for breast cancer patients and benign breast tumor patients. Methods: We analyzed the clinicopathological information of 191 breast cancer patients and 187 benign breast tumor patients by conducting a retrospective chart review. The preoperative diagnostic tumor sizes were measured using physical examination, mammography and sonography in the benign breast tumor patients and they were additionally measured by computerized tomography and magnetic resonance imaging in the breast cancer patients. Body mass index (BMI) was defined as the ratio of the body weight in kilograms to the square of height in meters. Results: The tumor sizes measured by mammography (r=0.66) and physical examination (r=0.87) were highly correlated to the pathologic tumor size in the breast cancer patients and benign the breast tumor patients, respectively. Physical examination and magnetic resonance imaging had a tendency to overestimate the tumor size and sonography underestimated the pathologic tumor size in the breast cancer patients. The correlation coefficient for the physical examination was increased when the patient age was less than 50 years and the BMI was less than 25. Multiple regression analysis revealed that assessing the tumor size according to physical examination, mammography and sonography were effective for determining estimation of pathologic tumor size in the benign breast tumor patients, but assessing the tumor size by physical examination and sonography was not effective for determining the tumor size in breast cancer patients. Conclusion: Mammography and physical examination can be useful to estimate the pathologic tumor size in breast cancer patients and benign breast tumor patients, respectively. Physical examination can be useful to estimate the size when a breast tumor is palpable, the age of a patient is less than 50, and the BMI is less than 25.Devolli-Disha E, 2009, BOSNIAN J BASIC MED, V9, P131Almubarak M, 2009, ONCOLOGY-NY, V23, P255Price J, 2009, J MED IMAG RADIAT ON, V53, P69, DOI 10.1111/j.1754-9485.2009.02040.xTohno E, 2009, BREAST CANCER-TOKYO, V16, P18, DOI 10.1007/s12282-008-0082-8Uematsu T, 2008, BREAST CANCER RES TR, V112, P461, DOI 10.1007/s10549-008-9890-yUchida K, 2008, BREAST CANCER-TOKYO, V15, P165, DOI 10.1007/s12282-007-0024-xJiang YX, 2007, ULTRASOUND MED BIOL, V33, P1873, DOI 10.1016/j.ultrasmedbio.2007.06.002Honjo S, 2007, JPN J CLIN ONCOL, V37, P715, DOI 10.1093/jjco/hym090Kim DY, 2007, KOREAN J RADIOL, V8, P32Fasching PA, 2006, EUR J RADIOL, V60, P398, DOI 10.1016/j.ejrad.2006.08.002Greene T, 2006, J AM COLL SURGEONS, V203, P894, DOI 10.1016/j.jamcollsurg.2006.08.017Watermann DO, 2005, ULTRASOUND MED BIOL, V31, P167, DOI 10.1016/j.ultrasmedbio.2004.11.005Cheung YC, 2004, ANN SURG ONCOL, V11, P756, DOI 10.1245/ASO.2004.12.008Bosch AM, 2003, EUR J RADIOL, V48, P285, DOI 10.1016/S0720-048X(03)00081-0CHOI GH, 2003, J KOREAN SURG SOC, V58, P331LEE CS, 2003, J BREAST CANCER, V6, P87Weatherall PT, 2001, J MAGN RESON IMAGING, V13, P868Saarenmaa I, 2001, BREAST CANCER RES TR, V67, P117Evans N, 2000, CLIN RADIOL, V55, P261Buchberger W, 1999, AM J ROENTGENOL, V173, P921Herrada J, 1997, CLIN CANCER RES, V3, P1565Davis PL, 1996, BREAST CANCER RES TR, V37, P1GORDON PB, 1995, CANCER, V76, P626MEDEN H, 1995, INT J GYNECOL OBSTET, V48, P193FOROUHI P, 1994, BRIT J SURG, V81, P223PAIN JA, 1992, EUR J SURG ONCOL, V18, P44FORNAGE BD, 1987, CANCER, V60, P765

An Analysis of Language Data of the 1994 Micro Population Census of the Russian Federation

The micro-population census of 1994 is the first full-scale nation-wide survey on population structure, economic situation and language since the breakup of the Soviet Union. The language data of this census has valuable information on the language situation of the Russain Federation. However, the publicized form of the language data does not represent the language situation properly and in detail. A statistical method, named "Speaker-composition analysis" provides us with a much more useful information and insight into hidden aspects of the language situation. This study provides basic data on the speaker composition of major nationalities and its change between 1989 and 1994. It also contains data on the language use of the urban and the rural population, at different social domains such as home, school and work places. The study shows that the linguistic assimilation among nationalities to the Russian language has been under way since the start of the new Russian Federation. Another challenge to the maintenance of national languages comes from the fast spread of Western foreign languages, especailly English, which has gained an ever more importance since the adoption of market economy system. One can speculate from this that the language situation of the Russian Federation would change to the Russiannational- English multilingualim or the Russan-Enghsh bilingualism. In this respect, surveys on language in the future should contain data on the influence of foreign languages
