BACKGROUND Neoadjuvant chemoradiotherapy does not alter anal sphincter preservation or postoperative complications compared with short-course radiotherapy alone in patients with clinical stage T3 or T4 resectable rectal cancer. The aim of this study was to compare survival, local control and late toxicity in the two treatment groups. METHODS The study(More)
We have undertaken a hospital-based study, to identify possible BRCA1 and BRCA2 founder mutations in the Polish population. The study group consisted of 66 Polish families with cancer who have at least three related females affected with breast or ovarian cancer and who had cancer diagnosed, in at least one of the three affected females, at age <50 years. A(More)
BACKGROUND AND PURPOSE The aim was to verify whether preoperative conventionally fractionated chemoradiation offers an advantage in sphincter preservation in comparison with preoperative short-term irradiation. PATIENTS AND METHODS Patients with resectable T3-4 rectal carcinoma without sphincters' infiltration and with a lesion accessible to digital(More)
Three mutations in BRCA1 (5382insC, C61G and 4153delA) are common in Poland and account for the majority of mutations identified to date in Polish breast and breast-ovarian cancer families. It is not known, however, to what extent these 3 founder mutations account for all of the BRCA mutations distributed throughout the country. This question has important(More)
PURPOSE The purpose of this study was to develop accurate models and nomograms to predict local recurrence, distant metastases, and survival for patients with locally advanced rectal cancer treated with long-course chemoradiotherapy (CRT) followed by surgery and to allow for a selection of patients who may benefit most from postoperative adjuvant(More)
OBJECTIVE The primary outcome was sphincter preservation. No benefit was found with chemoradiation. The aim of this report is to analyse postoperative complications, which were the secondary outcome. MATERIAL AND METHODS Patients with resectable T3-4 low rectal carcinoma were randomised to receive either pre-operative 5 x 5 Gy irradiation with subsequent(More)
PURPOSE Personalized treatments based on predictions for patient outcome require early characterization of a rectal cancer patient's sensitivity to treatment. This study has two aims: (1) identify the main patterns of recurrence and response to the treatments (2) evaluate pathologic complete response (pCR) and two-year disease-free survival (2yDFS) for(More)
We identified 4316 unselected incident cases of early-onset breast cancers (<51 ears of age at diagnosis) in 18 Polish hospitals between 1996 and 2003. We were able to obtain a blood sample for DNA analysis from 3472 of these (80.4%). All cases were tested for the presence of three founder mutations in BRCA1. The proportion of cases with a BRCA1 mutation(More)
There is increasing evidence that hereditary factors play a greater role in ovarian cancer than in any of the other common cancers of adulthood. This is attributable, to a large extent, to a high frequency of mutations in the BRCA1 or BRCA2 genes. In Poland, 3 common founder mutations in BRCA1 account for the majority of families with identified BRCA(More)
Linker histones H1 are key modulators of chromatin structure. Tightness of their binding to DNA is regulated by posttranslational modifications. In this study we have analyzed posttranslational modifications of five major variants of H1 in human tissue - H1.0, H1.2, H1.3, H1.4, and H1.5. To improve sequence coverage, tryptic peptides of H1 were separated by(More)
