[Attendance of the fourth (2008-2009) screening round of the Hungarian organized, nationwide breast cancer screening program]. / A szervezett országos emloszurési program negyedik (2008-2009) szurési körének részvételi arányai.

INTRODUCTION: Organised, nationwide screening for breast cancer with mammography in the age group between 45 and 65 years with 2 years screening interval started in Hungary in January 2002. AIM: The aim of this study is to analyze the attendance rate of nationwide breast screening programme for the 2008-2009 years. METHOD: The data derive from the database of the National Health Insurance Fund Administration. The ratio of women in the age group 45-65 years was calculated having either a screening mammography or a diagnostic mammography in the 4th screening round of the programme. RESULTS: In the years 2000-2001, 7.6% of the women had an opportunistic screening mammography while in 2008-2009 31.2% of the target population had screening mammography within the organized programme. During the same periods 20.2% (2000-2001) and 20.4% (2008-2009) of women had a diagnostic mammography. Thus the total (screening and diagnostic) coverage of mammography increased from 26.6% (2000-2001) to 50.1% (2008-2009). The attendance rate failed to change between 2002 and 2009. CONCLUSIONS: In order to decrease the mortality due to breast cancer, the attendance rate of mammography screening programme should be increased. Orv. Hetil., 154(50), 1975-1983.

Organised, nationwide screening for breast cancer with mammography in the age group of 45-65 years with 2 years screening interval started in Hungary in January 2002. The aim of this study is to analyse the attendance rate of breast screening programme for the 2006/2007 years, including the analysis of the ratio of screening and diagnostic mammography examinations. The data derive from the financial database of the National Health Insurance Fund Administration (NHIFA) covering the 8 years period between 2000 and 2007. The ratio of women in the age group of 45-65 years was calculated having either a screening mammography or a diagnostic mammography. The analysis was carried out for the years 2000-2001 before and 2006-2007 after the implementation of nationwide organised programme. In the years 2000-2001 7.26% of the women aged 45-65 years had an opportunistic screening mammography while in 2006-2007 29.4% of the target population had screening mammography within the organised programme. During the same periods 19.8% (2000-2001) and 21.8% (2006-2007) of women aged 45-65 years had a diagnostic mammography. Thus the total (screening and diagnostic) coverage of mammography increased from 26.2% (2000-2001) to 49.7% (2006-2007). The attendance of the Hungarian organised breast cancer screening programme slightly declined in 2006-2007 compared to 2002-2003/2004-2005, and to achieve the expected results in mortality decrease a further improvement of the uptake is necessary.

Triple test score for the evaluation of invasive ductal and lobular breast cancer.

The aim of our study was to compare the preoperative sum score diagnostics of invasive ductal and lobular cancers using three or four diagnostic methods. The novelty of this study is the examination of this phenomenon based on sum score, no such papers can be found in the literature. Ductal cancers have higher score values indicating easier diagnostics, but the difference in distribution of the scores was significant (p = 0.0086) only in case of the triple-test. The score values give appropriate opportunity to create their order of diagnostic power which was the same by both histologic types and in their subgroups with low sum-score: the strongest was cytology, followed by mammography, ultrasound and physical examination. No significant difference was found between the two histologic group in their mammographic appearances-stellate, circumscribed, assymmetric distortion or microcalcification-(p = 0.0694). In low score subgroup besides the occult forms, structural distortion and indeterminate microcalcifications overweighed the stellate and circumscribed lesions typical for the whole groups. In symptomless cases of both histologic groups only one strongly malignant diagnostic test result warrants the right diagnosis. Summarizing the score distribution of the results in case of four diagnostic tools the higher scores-indicating malignancy-were more frequent in the ductal group compared to the lobular ones. Extra attention has to be paid to rare radiomorphologic appearances and to the most deterministic examination, namely cytology.

[Combined surgery and radiotherapy in the treatment of ductal carcinoma in situ of the breast: preliminary results of the Hungarian multicenter prospective randomised study]. / In situ duktális emlokarcinóma kombinált sebészi- és sugárkezelése: a magyarországi multicentrikus prospektív.

The aim of this work is to report the preliminary results of the Hungarian multicentric randomised DCIS study. Between 2000 and 2007, 278 patients with ductal carcinoma in situ (DCIS) treated by breast-conserving surgery were randomised according to predetermined risk groups. Low/intermediate-risk patients (n=29) were randomised to 50 Gy whole-breast irradiation (WBI) or observation. High-risk cases (n=235) were allocated to receive 50 Gy WBI vs. 50 Gy WBI plus 16 Gy tumour bed boost. Very high-risk patients (patients with involved surgical margins; n=14) were randomised to 50 Gy WBI plus 16 Gy tumour bed boost or reoperation (reexcision plus radiotherapy or mastectomy alone). Immunohistochemistry (IHC) was performed to detect the expression of potential molecular prognostic markers (ER, PR, Her2, p53, Bcl-2 and Ki-67). At a median follow-up of 36 months no recurrence was observed in the low/intermediate- and very high-risk patient groups. In the high-risk group, 4 (1.7%) local recurrences and 1 (0.4%) distant metastasis occurred. No patient died of breast cancer. In the high-risk group of patients, the 3- and 5-year probability of local recurrence was 1.1% and 3.1%, respectively. The positive immunostaining for Her2 (38%), p53 (37%) and Ki-67 (44%) correlated with a high nuclear grade. Significant inverse correlation was found between the expression of ER (77%), PR (67%), Bcl-2 (64%) and grade. Preliminary results suggest that breast-conserving surgery followed by radiotherapy yields an annual local recurrence rate of less than 1% in patients with DCIS. IHC of molecular prognostic markers can assist to gain insight into the biologic heterogeneity of DCIS.

AIM: Organised, nationwide screening for breast cancer with mammography in the age group of 45-65 years with a 2-year screening interval started in Hungary in January 2002. The aim of this study is to analyze the attendance rate of breast screening programme, including the analysis of the ratio of screening and diagnostic mammography examinations. DATA AND METHODS: The data derive from the financial database of the National Health Insurance Fund Administration (NHIFA) covering the 6-year period between 2000-2006. The ratio of women in the age group of 45-65 years was calculated having either a screening mammography or a diagnostic mammography. The analysis was carried out for the years 2000-2001 before and 2002-2003, 2004-2005 after the implementation of nationwide organised programme. RESULTS: In the years 2000-2001 7.26% of the women aged 45-65 had an opportunistic screening mammography, while in 2002-2003 34% and in 2004-2005 29.5% of the target population had screening mammography within the organised programme. During the same periods 19.8% (2000-2001), 22.1% (2002-2003) and 23.2% (2004-2005) of women aged 45-65 had a diagnostic mammography. Thus the total (screening and diagnostic) coverage of mammography increased from 26.2% (2000-2001) to 53.5% (2002-2003) and 50.8% (2004-2005). CONCLUSIONS: Attendance of the Hungarian organised breast cancer screening programme slightly declined in 2004-2005, and to achieve the expected results in decline of mortality further improvement of attendance is necessary.

Radial scar-significant diagnostic challenge.

The prevalence of radial scar (RS) is 0.04% in asymptomatic women participating in population screening for breast cancer. It is important to differentiate RS from concomitant malignancies, which occur in 20-30% of patients, or from small stellate carcinomas which give similar radiomorphology. The aim of our study was to evaluate the effectivity of current breast diagnostic methods in distinguishing between real RS, concomitant malignancy and carcinomas imitating RS. Diagnosis of RS was set up in 61 cases by mammography. Forty-four patients underwent surgical excision: histology showed benign or malignant lesions in 28 and 16 cases, respectively. A series of negative results at follow-up proved the benign nature of the lesion in further 11 cases. Six patients were not available for follow-up. Results of mammography, physical examination, ultrasonography and cytology were evaluated and were compared in 39 benign and 16 malignant cases. Results of examinations were reported on the BI-RADS scale ranging from 1 to 5. The mean categorical scores of all diagnostic processes were around the level of borderline lesions: mammography: 3.49, ultrasonography: 3.06, cytology: 2.47 and physical examination: 1.67. The average age of the patients in the benign and malignant groups were the same: 58 years. The two groups did not differ significantly over either distribution of coded mammographical results (p = 0.2092), or the distribution of mammographical parenchyma density patterns (p = 0.4875). However, the malignant and benign groups differed significantly from each other over the distribution of coded ultrasonographic (p = 0.0176) and cytological (p < 0.0001) results. In conclusion, in the preoperative diagnosis of asymptomatic "black-stars", mammography detects the non-palpable lesions, and ultrasonography together with cytology proved better in the analysis, provided FNAB is US guided. Due to the complex diagnostic approach the nature of the "black stars" is known in the majority of cases prior to the surgical biopsy.

The role of radiotherapy in the conservative treatment of ductal carcinoma in situ of the breast.

Breast-conserving surgery (BCS) followed by radiotherapy (RT) has become the standard of care for the treatment of early-stage (St. I-II) invasive breast carcinoma. However, controversy exists regarding the value of RT in the conservative treatment of ductal carcinoma in situ (DCIS). In this article we review the role of RT in the management of DCIS. Retrospective and prospective trials and meta-analyses published between 1975 and 2007 in the MEDLINE database, and recent issues of relevant journals/handbooks relating to DCIS, BCS and RT were searched for. In retrospective series (10,194 patients) the 10-year rate of local recurrence (LR) with and without RT was reported in the range of 9-28% and 22-54%, respectively. In four large randomised controlled trials (NSABP-B-17, EORTC-10853, UKCCCR, SweDCIS; 4,568 patients) 50 Gy whole-breast RT significantly decreased the 5-year LR rate from 16-22% (annual LR rate: 2.6-5.0%) to 7-10% (annual LR rate: 1.3-1.9%). In a recent meta-analysis of randomised trials the addition of RT to BCS resulted in a 60% risk reduction of both invasive and in situ recurrences. In a multicentre retrospective study, an additional dose of 10 Gy to the tumour bed yielded a further 55% risk reduction compared to RT without boost. To date, no subgroups have been reliably identified that do not benefit from RT after BCS. In the NSABP-B-24 trial, the addition of tamoxifen (TAM) to RT reduced ipsilateral (11.1% vs. 7.7%) and contralateral (4.9% vs. 2.3%) breast events significantly. In contrast, in the UKCCCR study, TAM produced no significant reduction in all breast events. Based on available evidence obtained from retrospective and prospective trials, all patients with DCIS have potential benefit from RT after BCS. Further prospective studies are warranted to identify subgroups of low-risk patients with DCIS for whom RT can be safely omitted. Until long-term results of ongoing studies on outcomes of patients treated with BCS alone (with or without TAM or aromatase inhibitors) are available, RT should be routinely recommended after BCS for all patients except those with contraindication.

[Invasive lobular breast cancer: pitfall for the radiologist?]. / Invazív lobularis emlorák--csapdában a radiológus?

BACKGROUND: Invasive lobular carcinoma accounts for 5-10% of all breast cancers and is associated with subtle clinical and mammographic changes. It is also frequently multifocal and traditional diagnostic methods are unable to reliably detect this preoperatively. The aim of the study was to evaluate the ability of current imaging modalities to detect and analyze invasive lobular carcinomas as compared to invasive ductal carcinomas. MATERIAL AND METHODS: A retrospective analysis of 396 invasive carcinomas - 331 ductal (84%) and 65 lobular (16%) - between 2000 and 2002 was performed. The two group were compared on the basis of result of mammography, physical examination, ultrasound, and cytology using a coded system points 1-5 concerning the malignancy. RESULTS: The sensitivity of mammography and sonography for malignancy were higher in case of ductal carcinomas (81%, 77.4%), then by lobular cancers (75%, 72.2%), but the differences were not significant (p=0.4693 and p=0.4227 respectively). The radio-morphologic analysis shows the most frequent image was the stellate lesion in both group, but the difficult detectable structural distortions were found in 14.2% in lobular cancer- group, but only in 5.1% in case of ductal cancers without significance (p=0.5523). The clinical examination could predict the malignancy least of all, in the ductal group 42%, in the lobular group 40.2%. The cytology produced the best diagnostic result for malignancy in the ductal group 86.2%, and in the lobular group 76.5% was observed, the difference is significant (p=0.0069). CONCLUSION: Although all elements of triplet diagnostics produces were more uncertain for malignancy in case of lobular carcinomas than ductal one, combining the result of the three radiological modalities and cytology increase the preoperative detection rate of lobular carcinoma.

[The attendance of the first screening round (2002-2003) of the Hungarian organized breast cancer screening program and its effect on the number of diagnostic and screening mammography]. / A szervezett emloszurési program 2002-2003. évi részvételi arányai és a program hatása a diagnosztikus és szurési célu mammográfiák számára.

AIM: Organised, nationwide screening for breast cancer with mammography in the age group 45-65 years with 2 years screening interval started in Hungary in January 2002. The aim of this study is to analyze the attendance rate of breast screening programme, including the analysis of the ratio of screening and diagnostic mammography examinations. DATA AND METHODS: The data derive from the financial database of the National Health Insurance Fund Administration (NHIFA) covering the period 2000-2003. The ratio of women was calculated in the age group 45-65 years having either a screening mammography or a diagnostic mammography. The analysis was carried out for the years 2000-2001 (mainly opportunistic screening) before and 2002-2003 after the implementation of nationwide organized programme. RESULTS: In the years 2000-2001 7,26% of the women aged 45-65 had an opportunistic screening mammography while in 2002-2003 33,95% of the target population had screening mammography within the organized programme. During the same periods 19,67% (2000-2001) and 22,05% (2002-2003) of women aged 45-65 had a diagnostic mammography. Thus the total (screening and diagnostic) coverage of mammography increased from 25,85% (2000-2001) to 53,46% (2002-2003). CONCLUSIONS: The attendance of the Hungarian organized breast cancer screening programme - compared to the previous period before the implementation of the organized screening programme - is promising, although to achieve the expected results in mortality decrease a further improvement of the uptake is necessary.

[Effect of hormone replacement therapy on the mammographic density of the female breast]. / A hormonpótló kezelés hatása az emlo radiológiai denzitására.

BACKGROUND: Mammographic parenchymal patterns are of particular interest because the denser patterns reduce sensitivity and they have been shown to be affected by exogenous oestrogens. PURPOSE: To evaluate the possible effects of peri- and postmenopausal hormone replacement therapy (HRT) on the mammographic density in the different types of parenchymal patterns. PATIENTS AND METHODS: During a period of 7 years (average: 3.44), 1158 women with combined or monophasic HRT were checked with mammography yearly. Their base-line mammograms were compared with those of 1433 screening participants of the same age (average 56 years). Mammograms were evaluated according to the Tabar classification. We studied the changes in density between two examinations in the HRT group, especially in the subgroup with benign lesion. RESULTS: In comparison of the HRT and screening group, the distribution of their parenchymal patterns were similar. Pattern I (glandular) and II (adipose) eventually dominated, 38.9% and 47.9% in the HRT group, and 34.0% and 42.2% in the screening group. Pattern IV (adenotic) and V (fibrotic) types have been found in 8.9% of the HRT group, and 13.1% of the screening group. During HRT, an increase of breast density has developed after a few months, then it remained unchanged. Density increased in 30.8% of the whole HRT group, and in 38.0% of women who had benign lesions as well. Although there was a significant increase in breast density in case of pattern I-II and III (p=0.0013), pattern IV and V remained totally unchanged. The distribution of the patterns has changed significantly (p=0.0000) during HRT: the proportion of pattern I (glandular) type increased from 38.9% to 51.3%, pattern II (adipose) decreased from 47.9% to 30.6%, while the IV (adenotic) and V (fibrotic) types together showed no change. CONCLUSION: Careful clinical and mammographic follow-up might be appropriate in women undergoing HRT, especially in those with benign lesion, because the HRT-induced increase in breast density proved significant.
