[Our experiences with the use of phosphor plate X-ray system and PACS]

BARTA H. Miklós, BERENTEY Ernő, FORNET Béla, FORRAI Gábor

[In this study the experiences, the advantages and disadvantages of a full digital radiology department are presented. The conventional radiology and the spot films of gastroenterologic studies are exposed on phosphor plates since 1999 at our department. Two work-stations are used for making the reports and six viewing-stations are installed at distant departments. A central server organizes the data and pictures flow and the archive system consists of magnetooptical discs in a juke-box. The conventional X-ray methods are fully integrated in the system. The number of hardcopies is dramatically decreased. The clinicians may easily access the images on the viewingstations. Possibility of teleradiology and teleconsultation is integrated in the system. The quality of the examinations is improved and became uniform. The images of different methods (CT, fluoroscopy) are stored also in digital format. The disadvantages are the high cost of installation, a new workflow and reporting habits must be initiated. A problem of one element can cause the breakdown of the whole system. The new technics, the digital world forces us to develope and define new technical standards in order to obtain uniform quality.]

[Radial scar associated with lobular neoplasia in the breast]

ERDŐSI Éva, HERTELENDY Ágnes, GREXA Erzsébet, ANGA Béla, VARGA Zoltán

[INTRODUCTION - The authors are presenting the case of a 55-year-old female patient with breast abnormalities of unclear morphology. CASE REPORT - The lesion seen in the left breast was characteristic of radial scar in which, however, numerous, but not clearly benign microcalcifications were detected. During histological examination a radial scar associated with a small lobular neoplasia was diagnosed. However, these microcalcifications were not related to the malignancy. CONCLUSION - In radial scar extensive benign microcalcifications may develop. Nevertheless we should bear in mind that in 10-30% of cases this disorder can be associated with malignancy even without mammographic signs. The final diagnosis, however, should always be made on the basis of histological examination.]

[Cheirospondyloenchondromatosis]

IGNYS Anna, MALGORZATA Krajewska-Walasek, MARIKOVA Olga, IVO Marik, KAZIMIERZ Kozlowski

[The term of cheirospondyloenchondromatosis (CHE) was coined by Spranger et al. This generalised, distinctive form of enchondromatosis is characterised by mild to moderate dwarfism, short hands and feet with beaded fingers, prominent large joints and frequently mental deficiency. Major radiographic features include generalised mild platyspondyly, generalised enchondromatosis with marked involvement of hands and feet and small ilia with eroded crests and acetabular roofs. We report three patients with this rare, severe form of enchondromatosis and stress some differences between our patients and the classical description of Spranger et al.]

[Intersphincteric resection for low rectal tumors]

METZGER Péter

[The technical development of rectal surgery, together with chemo- and radiotherapy, improved the effi ciency of surgical intervention as well as the patients‘ survival and quality of life. The treatment of ultra deep malignancies - 2-3 cm from linea dentata - is a real challenge for rectal surgery. Before the introduction of laparoscopy the removal of the deep tumors with conventional surgical techniques was impossible to save the tumorous rectum. The new techniques made possible the ultra deep resection, i.e. the removal even those tumors which progressed until the linea dentata. The explosive use of laparoscopy and the new waves of chemo- and radiotherapy resulted signifi cance advance contributed to an interdisciplinary therapeutic approach, which is a well adapted method in deep rectal surgery. In case of ultra deep localization of tumors - 0.5-1.0 cm to linea dentata - the neoadjuvant therapy supported the saving the anal sphicter. This new techniques contributed to the preservation of feces continentia of the patient.]

[Targeted therapy: based upon the primary tumor or on its metastases?]

TÍMÁR József

[Most of the primary tumors at various stages are resected or destroied by radiotherapy. Meanwhile, contemporary target therapies are administered in advanced stages, but the required molecular pathologic analysis is performed on the primary tumor supposing stable genetic profi ls durings at different stages of cancer progression. Advanced molecular technologies provided high resolution images on the clonal heterogeneity of the primary tumors and its role in cancer progression. Data indicate that in early and locoregional stages/recurrences the chance for genetic discordance is low while, in late visceral metastases this risk is increasingly higher. The clinical relevance of the genetically discordant metastatic tumors is proven by several retrospective studies. This is the basis of the recommendations that in case of progressing cancer molecular pathologic tests must be performed on metastatic tumors, especially when the primary tumor is resected. On the other hand, it is an unresolved issue what to do in case of discordance between the primary and the metastasis.]

[Combination of radiotherapy and immunotherapy]

HIDEGHÉTY Katalin, BRUNNER Szilvia, SZABÓ Zoltán Imre, SZABÓ Emília Rita, POLANEK Róbert, TŐKÉS Tünde

[Increasing experimental and clinical evidences demonstrated the synergic effect between the rapidly implemented immunotherapy and advanced forms of focal radiotherapy, not only on the elimination of the irradiated lesion, but also on the enhancement the immune-mediated systemic anti-tumoral activity. It is essential for gaining the most benefi t from the combination of the two modalities to select the appropriate patients, to defi ne the irradiation parameters, such as radiation quality (ie. particle) dosage, (total dose, fraction number) size of the target volume, the use of other supportive and anti-tumor drugs. In this review, we provide an update for the daily oncological practice on the data accumulated up to now on the molecular basis and patomechanism of enhancing radio-immune effect and clinical results, and highlight the most important parameters, which may increase the abscopal effect of ionizing radiation, thereby increasing the effectiveness of immunotherapy. However, development of clinical guidelines for benefi cial integration of immunotherapy and radiotherapy could be expected after evaluation the result of currently ongoing numerous (> 100) clinical trials. If the preclinical results will be confi rmed clinically, it could lead to paradigm shift in the use of ionizing radiation.]

[Current management of GIST]

LAKATOS Gábor, BODOKY György

[Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. GISTs are generally resistant to chemotherapy and radiotherapy. The understanding of pathology at molecular level promised the development of novel treatment modalities. KIT and PDGFRA gene mutations play an important role in the pathogenesis of GIST. IMutational analysis should be considered as standard practice during the diagnostic work-up, since it has a predictive value for sensitivity to molecular-targeted therapy and also has prognostic value. The aim of this review is to summarize recent knowledge about diagnosis, treatment and follow up of GIST.]

[Pilomatrix carcinoma with a lymph node metastasis - First Hungarian publication of a rare case]

VAJDA Adrienne, LÉVAY Bernadett

[INTRODUCTION - Pilomatrix carcinoma is a very rare malignant tumour, which derives from hair matrix cells. The male:female ratio among patients is 4:1, the mean age of patients is 45 years. This tumour type is very aggressive and grows slowly. CASE REPORT - The authors describe the case of a 37-year-old man who presented in 2004 with an approximately 2×2 cm, compact lesion tumour in the lumbar region. The tumour was excised and diagnosed as carcinoma sebaceum on the basis of histological examination. Several weeks after surgery, a protruding, semi-spherical lesion with a diameter of 2 cm appeared in the scar. The patient was referred to our hospital for excision of this lesion and for assessing the possibility of Muir-Torre syndrome. The examinations did not indicate the presence of any internal tumours. The recurrent tumour was excised with a 2 cm intact margin. Histological examination confirmed the diagnosis of pilomatrix carcinoma. In 2005, two new tumours were excised and semithick skin was transplanted in several sessions. At an oncological follow-up examination in 2009, a 13×7 mm lymph node was felt in the righ inguinal region, which was found to be a metastasis of pilomatrix carcinoma on the basis of aspiration cytology. Surgical block dissection was performed, followed by postoperative radiotherapy at a dose of 25×2 Gy. At present, the patient is symptom- free. Thoracic-abdominal CT and clinical examination performed in early June 2011 did not indicate progression of the original disease. CONCLUSION - Pilomatrix carcinoma with a lymph node metastasis has not been previously reported in Hungarian. The diagnosis was established on the basis of histological examination, which was indispensable for successful treatment.]
