“Purpose: The patterns of care study (PCS) of radiotherapy for cervical cancer in Japan over the last 10 years was reviewed.\n\nMethods and Materials: The Japanese PCS working group analyzed data from 1,200 patients (1995-1997, 591 patients; 1999-2001, 324 patients; 2003-2005, 285 patients) with cervical cancer

treated with definitive radiotherapy in Japan.\n\nResults: Patients in the 2001-2003 survey were significantly younger than those Torin 2 in the 1999-2001 study (p < 0.0001). Histology, performance status, and International Federation of Gynecology and Obstetrics stage were not significantly different among the three survey periods. Use of combinations of chemotherapy has increased significantly during those periods (1995-1997, 24%; 1999-2001, 33%; 2003-2005, 54%;

p < 0.0001). The ratio of patients receiving concurrent chemotherapy has also dramatically increased (1995-1997, 20%; 1999-2001, 54%; 2003-2005, 83%; p < 0.0001). As for external beam radiotherapy (EBRT), the application rate of four-field portals has greatly increased over the three survey periods (1995-1997, 2%; 1999-2001, 7%; 2003-2005, 21%; p < 0.0001). In addition, the use of an appropriate beam energy for EBRT has shown an increase (1995-1997, 67%; 1999-2001, 74%; 2003-2005, 81%; p = 0.064). As for intracavitary brachytherapy (ICBT), an iridium source has become increasingly Buparlisib chemical structure Vactosertib popular (1995-1997, 27%; 1999-2001, 42%; 2003-2005, 84%; p < 0.0001). Among the three surveys, the ratio of patients receiving ICBT (1995-1997, 77%; 1999-2001,

82%; 2003-2005, 78%) has not changed. Although follow-up was inadequate in each survey, no significant survival differences were observed (p = 0.36), and rates of late Grade 3 or higher toxicity were significantly different (p = 0.016).\n\nConclusions: The Japanese PCS has monitored consistent improvements over the past 10 years in the application of chemotherapy, timing of chemotherapy, and EBRT methods. However, there is still room for improvement, especially in the clinical practice of ICBT. (C) 2012 Elsevier Inc.”
“Aims:\n\nTo test the hypothesis that the similarity of the molecular subtypes of Paget’s cells to the molecular subtypes of the underlying breast carcinomas favours the epidermotrophic theory of the origin of Paget’s cells.\n\nMethods and results:\n\nThe immunohistochemical expression of markers that define particular molecular subtypes of breast carcinomas were analysed. The whole analysis was performed by means of tissue microarrays in mammary Paget’s disease and in the underlying breast carcinoma(s). Human epidermal growth factor receptor type 2 (HER2)-overexpression subtype [oestrogen receptor (ER-); HER2+] was a dominant molecular subtype of Paget’s cells (37 of 43 analysed cases; 86%).
