[The role of PET in clinical oncology]

LENGYEL Zsolt

[Positron emission tomography (PET) has earned an important role in clinical imaging, where it is used almost exclusively as hybrid modality such as PET/CT and PET/MR. The driving force behind the development of the method and the increasing clinical penetration of PET in the past two decades was clearly its use in Oncology. The most used tracer in PET is the 18 F-labeled fl uoro-deoxy-glucose (FDG). With the help of this molecule malignant tumors and their metastases, in which anaerobic glycolysis is typically increased, can be identifi ed with high sensitivity in the total body volume. However, FDG is not a tumor specifi c tracer, thus both false positivity and false negativity may occure which reduces the diagnostic accuracy. Indications of FDG PET studies in Oncology continuously evolved, owing to scientifi c publications, large scale national programs and even health-economic considerations. This publication describes the well-established indications of FDG PET/CT(MR) tests in cancer diagnostics and furthermore discusses more recent new PET tracers already being applied as well as those expected to be used in the future.]

[New challenges and possibilities in the chemotherapy of small cell lung cancer]

SZONDY Klára, OSTOROS Gyula

[The small cell lung cancer is characterized as a rapidly proliferating systemic neoplasm, where the basic treatment modality is the chemotherapy . Even in the surgically treated cases the platina based chemotherapy combination is obligatory before and after the surgical resection, combined with preventiv cranial irradiation to minimize the risk of the cranial metastases. The platina based chemo-radiotherapy is the gold standard in the locally advanced cases. Palliativ local irradiation could be useful for pain relief or decompression in the metastatic cases. Prophylactic cranial irradiation strongly recommended in any cases. There are no newly developed drugs for the treatment of SCLC, however it is a chemosensitive carcinoma. Topotecan could be effective in second or third line therapy , especially in brain metastasis.]

[Recognizing colorectal cancer, education of patients and preparing them for the stomal therapy]

TUSÓCZKI Evelin, NÉMETH Anikó

[Aim of the research: The study investigated the circumstances of the diagnosis of the disorder. The assessment of information given to patients, communication of the staff and the preparation for the stomal therapy was also part of the study. Research and sampling methods: A self-constructed questionnaire was administered during October and December of 2015. The inventory was uploaded to self-help sites for colorectal cancer patients and questionnaires were also handed out on surgical wards (N=114). Data were analysed with SPSS 22.0. Chi square, Mann-Whitney and Kruskal-Wallis tests were applied (p<0.05). Results: Colorectal cancer screening has never been attended by 81.6% of the responders. Constipation was a more frequent warning sign by women (p=0.045). The patients who received guidance from both doctors and nurses about oncology treatment were more satisfied with the information compared to those who only communicated with one person (p<0.001). The patients who could contact a stomal therapy nurse on-demand were able to handle their stomas autonomously (p=0.035). Conclusions: Information provided by more staff members help to dissolve anxiety. Contacting stomal therapy nurses on-demand should be preferred. ]

Watershed infarction in hypereosinophilic syndrome: a diagnostic dilemma in FIP1L1-PDGFR alpha-associated myeloid neoplasm

IMELDA Marton, PÓSFAI Éva, ANNUS János Kristóf, BORBÉNYI Zita, NEMES Attila, VÉCSEI László, VÖRÖS Erika

Introduction - The FIP1L1-PDGFR alpha-positive, hypereosinophilic syndrome (HES) is a new category of hematological entities. Various clinical symptoms may occur, with no specific characteristics in either the clinical picture or the neuroimaging findings, and this may give rise to a diagnostic dilemma. A report on a long follow-up period (10 years) in a case of HES that presented with neuropsychiatric symptoms appears to be unique. Besides the complexity of the diagnostic process, the successful treatment is discussed. Case report - The HES was diagnosed in a male patient at the age of 33 years, with involvement of the central nervous system and the myocardium. After the onset of the clinical signs, the MRI indicated bilateral cerebral and cerebellar cortico-subcortical lesions involving the watershed areas, mainly in the parieto-occipital regions. High-dose intravenous steroid (methylprednisolone 500 mg/day) alleviated the neurological symptoms within a few weeks, and the administration of imatinib (200 mg/day) resulted in an impressive regression of the hypereosinophilia and splenomegaly within 6 weeks. During the follow-up, the patient has continued to receive imatinib. The molecular remission has persisted, no new complaints have developed and the condition of the patient has remained stable. Conclusion - The timely recognition of the HES and identification of the disease subtype which led to the administration of imatinib may be the key to successful treatment. The long stable follow-up period gives rise to a new dilemma in the treatment of the HES in these special cases: for how long should a patient receive a tyrosine kinase inhibitor, and may the treatment be suspended?

[Central nervous system hemorrhage in Wegener’s granulomatosis]

SZABOLCSI Orsolya, SZÁNTÓ Antónia, ZEHER Margit

[In our case a 41-year-old man with following symptoms: non-productive coughing, fever, difficulty in breathing and weight loss was examined in February 2007, and on the basis of chest X-ray, CT and bronchoscopy, the possibility of neoplasm or tuberculosis cropped up. After the applied therapy (steroid, antibiotics, tuberculostatic drugs) the symptoms became more severe, i.e. hematuria and epistaxis were manifested. A tissue biopsy was carried out during bronchoscopy and the histological examination revealed granulomatous reaction. Meanwhile, the presence of c-ANCA was proved, and Wegener’s granulomatosis (WG) was diagnosed. In March 2007, sudden somnolence and left side hemiplegia developed, and a large haemorrhage was recognised on CT scan in the right fronto-temporal region, with regard to the haemorrhage, the patient had to undergo a neurosurgical operation. We started to treat him in April 2007 by intravenous steroid and 600 mg of cyclophosphamide (Cyc), and he regained the ability to walk again. In October 2007, the Cyc treatment was terminated, and we administered a maintenance therapy with methotrexat. During the regular medical check-up, a chest X-ray indicated a second attack in March 2008, which was confirmed by the chest CT, the clinical symptoms, increased anti-PR3 levels and c-ANCA positivity as well. The flair of the disease was established. Consequently, in April 2008 we decided on plasmapheresis therapy synchronised with Cyc. After that, we started an azathioprine maintenance therapy and he got rid of all the activation symptoms. We can say that with the adequate therapy started in good time and with the regular medical check up of the patient a good result can be achieved. It is true even in the case of WG disease associated by severe complication, for example central nervous hemorrhage.]

[The role of static MR-urography in diagnostics of urinary obstruction]

KIS Zsuzsanna, FAZEKAS Péter, KULCSÁR Dániel, KÖTELES Márta, KOVÁCS Annamária, MAGYAR Klára

[INTRODUCTION - The idea and methodology of MRurography has just crystallized recently due to the development of technology. The traditional MRU technology means the strongly T2 weighted sequence, suitable for depicting stationary liquid spaces. Its use is independent of the functional status of the kidneys thus it is suitable for depicting dilatated ureters in case of nonfunctioning kidneys, too. Authors's aim was to define the role of sMRU in the diagnostics of obstructive urinary diseases. PATIENTS AND METHODS - 60 sMRU examinations were performed on 59 patients using a 1.5 T Siemens Symphony MR scanner in the CT-MR Laboratory of the Markhot Ferenc County Hospital between May 1, 2003 and October 31, 2005. The sMRU was performed with 2D T2 TSE sequence with angiographic character. In each case, the examinations were completed with conventional sequences in multiple planes. The role of gadolinium enhanced T1-weighted MR urography in the same diseases was not studied. In 7 cases, low-dose thin slice CT examination was performed to reveal the precise cause of obstruction. The examinations were preceded by abdominal ultrasound or intravenous urography (IVU). RESULTS - Out of the 60 sMRU examinations uretery dilatation were observed in 50 cases. In the background of obstruction, stone could be detected in 13 patients, dilatation was observed in 4 patients and MR did not indicate stone. In 7 cases with known neoplastic disease, associated urinary obstruction could be detected. In the background of obstruction primary neoplasm was found in 10 patients unknown prior the MR examination. Other benign obstruction occurred in 13 cases. Obstruction was not proved in 10 patients. In these cases the examination was justified by uncertain ultrasound findings together with abnormal renal function parameters. Follow up sMRU was performed in one patient. False diagnosis was established in two patients, the cause of dilatation was not found in one patient. CONCLUSIONS - The sMRU examination can provide more precise detection of the causes of severe urinary obstructions. It helps to define the level of obstruction in case of known malignant tumors. The grade of urinary dilatation could be also evaluated. The sMRU examination in conjunction with conventional sequences in multiple planes made possible to set up a correct therapy plan.]

[Radiological diagnosis of lung cancer - 2005 Literature review Onco Update 2005]

BALÁZS György

[Our aim is to review the radiologic literature of lung cancer of 2004 and some remarkable publications from 2003. There are three main groups in the recent publications dealing with lung cancer’s radiology. The first group comprises those reviews and metaanalyses which focus on the overall utility and reliability of routinely applied modalities such as CT and MRI. In the second group we find original articles reporting on the experience with new modalities. This group is dominated by publications dealing with positron emission tomography and the first clinical results of combined PET-CT technology. In the third part we review those articles dealing with lung cancer screening. Radiological lung cancer screening is in the focus of interest again, mainly due to the introduction of low-dose CT which is undoubtadly the most sensitive radiological modality for the early detection of lesions, however, its clinical utility is debated. The papers referred are basically sceptic, but this is not the end, because controlled long term follow-up studies are still in progress. Part of the publications report on the first clinical results of new methods, while others give valuable additional data regarding the performance of “well established” radiological modalities.]

[Gastrointestinal stromal tumors]

BAHÉRY Mária

[Gastrointestinal stromal tumors are the most common mesenchymal neoplasm of the gastrointestinal tract. Gastrointestinal stromal tumors are characterized by remarkable variability in their differentiation potential. They are defined by their expression of KIT (CD117), a tyrosine kinase growth factor receptor. The expression of KIT is important to distinguish gastrointestinal stromal tumors with immunohistochemically method from other mesenchymal neoplasms such as leiomyomas, leiomyosarcomas, leiomyoblastomas and schwannomas. Pathologically proved gastrointestinal stromal tumors are appropriate KIT-inhibitor therapy. Gastrointestinal stromal tumors arise with variable frequency throughout the gastrointestinal tract, they most frequently occur in the stomach (40-70%), followed by the small intestine (20-30%), colorectum (5- 15%) and esophagus (<5%). The most gastrointestinal stromal tumors arise within the muscularis propria, they most commonly have an exophytic growth pattern and manifest as dominant extraluminal masses. Radiologic features of gastrointestinal stromal tumors vary depending of tumor size and organ of origin. They are characteristically well circumscribed, sharply defined and have hemorrhage, necrosis or cyst formation. The radiologic features of gastrointestinal stromal tumors are often distinct from those of epithelial tumors. There are no specific radiologic features to separate gastrointestinal stromal tumors from other mesenchymal tumors, yet.]

[RARE UTERINE MALIGNANCY: THE ENDOMETRIAL ADENOSARCOMA]

TARJÁN Miklós, SÁPI Zoltán, BENTZIK András, CSERNI Gábor

[INTRODUCTION - Müllerian adenosarcoma is typically composed of benign glandular epithelial elements admixed with malignant sarcomatous stroma. This rare tumour usually originates in the endometrium and grows as a polypoid mass into the endometrial cavity. CASE REPORT - We report the case of a woman aged 32, who presented with abnormal vaginal bleeding and was diagnosed with an adenosarcoma after a curettage and subsequent hysterectomy. CONCLUSION - This tumour has a relatively good prognosis among the mixed mesenchymal sarcomas of the uterus and the majority of patients with this neoplasm survive. The gynecologists and pathologists should be aware of this entity and discuss the risks and benefits of radiation and chemotherapy, which is usually indicated for malignant diseases.]

[DIAGNOSTIC PROCEDURES AND SUCCESSFUL TREATMENT OF A RARE INTRAABDOMINAL NEOPLASM IN AN UNCOMMON LOCALISATION]

KIS János Tibor, PÁLHEGYI Erika

[INTRODUCTION - Primary neoplasms of the grater omentum are rarely revealed. The primitive neuroectodermal tumor of the grater omentum is extremely rare, only one case has been reported in the English literature. CASE REPORT - We report a case of an omental tumour occurring in a 50-year-old man with HBV-positive liver cirrhosis (Child C). The patient had regular check-ups in our outpatient clinic. One of the regular ultrasound scans revealed an epigastrial space-occupying lesion, which was not seen previously. The symptoms and the laboratory tests did not suggest an intraabdominal malignancy. Abdominal CT scan did not raise the suspicion of a neoplastic lesion either. Some weeks later a sudden increase in the amount of ascites has developed. A repeated abdominal ultrasound scan detected the tumour again. The reassessment of the CT scan provided some suspicion of the presence of an abdominal neoplasm. After draining the ascitic fluid by paracentesis an apple-sized nodule was palpable. Abdominal US-guided biopsy was performed. On histopathological examination the diagnosis of a primary peritoneal neuroectodermal tumour was made. Laparotomy proved the precise location but the tumorous conglomeration could not be removed as a whole. Following surgery the patient was treated in the oncology department and a significant improvement could be achieved. CONCLUSION - This case highlights the importance of the correlation of the clinical data and imaging techniques and the necessity of regular patient follow-up.]
