Clinical Oncology - 2016;3(02)

[Mesenchymal cells can be differentiated into skeletal muscle, smooth muscle, adipose tissue, fi brous tissue, bone and cartilage. Tumors can be originated from these tissues as benign tumors - fibroma, lipoma, osteoma, chondroma, haemangioma, myoma, etc. or as malignant tumors - in childhood, most commonly rhabdomyosarcomas, osteosarcoma, Ewing sarcoma, less often fi brosarcoma, liposarcoma or other rare types. Clinically, the outcome of these tumors have improved signifi cantly in the last decade due to the use of multi-modality treatment (chemotherapy, surgery, irradiation, in some cases targeted therapy). The better treatment results are based on early diagnosis and adequate management according to international treatment protocols in pediatric oncology centers.]

[Complications of infusion treatment with emphasis on extravasation of cytostatics]

HARISI Revekka

[The extravasation of cytostatics is the most signifi cant complication of infusion therapy in cancer treatment. Extravasation refers to the inadvertent infi ltration of cytostatic drugs into subcutaneous or subdermal tissues surrounding the intravenous or intraarterial administration site. According to literature data incidence estimates between 0,01-7%. Extravasated drugs are classifi ed according to their potential for causing damage as vesicant, irritant and nonvesicant. Knowledge of risk factors, the patientrelated and treatment-related ones is important to minimize the occurrence of extravasation. In order to reduce the risk of extravasation, the staff involved in the tumor infusion therapy must be specially trained to implement several preventive and therapeutical protocols. In 2012, ESMO-EONS has put together a new comprehensive treatment protocol on the topic of cytostatics extravasation. Protocol recommended that every oncological department, who administers chemotherapy have to have extravasation trained team and a standby extravasation kit. According to the new ESMO-EONS guideline subcutaneous corticoids are not recommended, anymore. In case of mechloretamine extravasation the recommendation is immediate subcutaneous injection of sodium thiosulfate. After extravasation of anthracyclines, mitomycin C and platin salts the best treatment opportunity is subcutan dimethyl sulfoxide administration. In case of anthracyclines’ extravasation intravenous dexrazoxane treatment is also effective. Hyaluronidase, injected into or under the skin, facilitates absorption of extravasated drugs because of increases connective tissue permeability, promotes the spreading and reduces the local concentration of the extravasated citostatic agents. Hyaluronidase might be effi cacious in preventing skin necrosis by extravasation due to vinca alkaloids. The treatment of unresolved tissue necrosis or pain lasting more than 10 days is surgical debridement. Because of the medical and juristic importance of the extravasation event, it is necessary to establish uniform guidelines for treatment of extravasation, in all Hungarian Oncological Centers.]

[Non-surgical treatment of the biliary tract and gallbladder cancer]

PIKÓ Béla, LACZÓ Ibolya

[Biliary tract cancers are rare, hence only a few high level of evidences related to their treatment are available. The successful treatment and the only chance for long-term survival are based on the radical surgical resection. After the fl uoropyrimidin based protocols chemotherapy regimens prefer gemcitabine combinations (cisplatin, oxaliplatin, capecitabine) or FOLFIRINOX, considering the patient performance status as well. There are no registered targeted therapy in this indication, the most experiences were acquired with erlotinib; nowadays the optimal treatment can be selected by the molecular genetic profi le of the tumour and not by the results of the clinical studies. The radiotherapy and the radiochemotherapy can be administered preoperatively, postoperatively and for palliation as well, in addition to the conventional percutaneous radiotherapy, brachytherapy, intensity-modulated radiotherapy, intraoperative irradiation, radioembolization can also be administered depending on the technical equipments. Besides the photodynamic therapy and several ablation therapies, even interventional radiological procedures can play a signifi cant role.]

[Mediastinal tumours and their therapy]

AGÓCS László

[Due to the tissue structure of the mediastinum a large variety of tumours and multiple systemic malignant disease may occur in the region. The tumours show a variation depending upon age and localization besides their signifi cant alterations. Based on the most accepted Shield classifi cation, the author discusses the types, characters and therapeutic discipline of the tumours in the mediastinal region. The author focuses on the surgical indications, their options and forms, highlighting on the minimal invasive methods.]

Association of anterior thoracic meningocele and azygos lobe of the lung

DENIZ Ersay Fatih, SENAYLI Atilla, BICAKCI Ünal

Here we report an anterior thoracic meningocele case. Twoyears- old female patient was presented with kyphosis. Azygos lobe of the lung was also demonstrated during radiological studies. Posterolateral thoracotomy incision and extralpeural approach was performed for excision of the anterior meningocele to untether the cord. Although both anomalies are related to faulty embryogenesis and it is well known that faulty embryogenesis may also reveal coexisting abnormalities, we could not speculate a common mechanism for anterior thoracic meningocele and azygos lobe of the lung association.

[Cancer-treatment induced peripheral neuropathy]

DEMETER Gyula

[Peripheral neuropathy is caused by structural or functional damage of nervous system. The pathophysiology is not well known. Its clinical features are established but there is a need to standardize CIPN assessment, also considering that health care providers and patients frequently have a different perception of CIPN severity. Neurotoxicity caused by traditional chemotherapy is widely recognized in patients with cancer. The adverse effects of newer therapeutics, such as targeting and immunotherapeutic agents, need more information for the proper management. This review addresses the main neurotoxicities of cancer treatments with a focus on the newer therapeutics. Recognition of these patterns of toxicity is important because drug discontinuation or dose adjustment might prevent further neurological injury. Treatment is symptomatic. For prevention or treatment there is need for further basic research outcomes.]

[Temozolomide chemotherapy of patients with recurrent anaplastic astrocytomas and glioblastomas]

SIPOS László, VITANOVICS Dusan, ÁFRA Dénes

[Introduction - Anaplastic astrocytomas and glioblastomas are the most frequent and most malignant hemispherial tumours. Unfortunately, astrocytic tumours are of infiltrative character and radical removal is not possible. Recurrent malignant gliomas are rarely suitable for reoperation. In most of the cases of recurrent gliomas chemotherapy is the last choice. Patients and method - Seventy-five consecutive patients with recurrent malignant astrocytomas and glioblastomas had been treated at our institute with per os temozolomide for five days every month. The patients received two to 16 courses of chemotherapy. The toxicity, quality of life, response to chemotherapy and survival data were analysed. Results - Out of 75 patients four were excluded following the first treatment due to myelotoxicity, and allergic reactions. Among the patients treated with temozolomide in seven cases complete response, 17 partial response, 14 progressive disease were observed. In 33 cases the disease stabilized and out of them in 27% a significant neurological improvement was detected. The time to progression was 6.8 months and the median survival time 8.75 months for patients with glioblastoma and with malignant astrocytoma or malignant mixed oligoastrocytoma 9.45 and 11.15 months, respectively. The overall survival for patients with originally lower grade glioma was 70.32 and for patients with glioblastoma multiforme 17.43 months. Conclusions - Temozolomide chemotherapy in patients with recurrent malignant astrocytoma and glioblastoma proved to be efficacious and similar good results were achieved as with a nitrosourea based combined chemotherapy. Even in those patients who received previous chemotherapy temozolomide is well tolerated and a relatively long time to progression was achieved in cases of recurrent malignant gliomas. In a few number of patients where BCNU had been previously failed with temozolomide stable disease was achieved. Temozolomide seems to be a promising drug in the chemotherapy of malignant gliomas and can be applied as a second line chemotherapy, as well.]

[Neoadjuvant treatment of rectal cancer]

PINTÉR Tamás

[Rectal cancer due to its frequent local invasion, high recurrence rate and metastatic potential is a serious health problem, leading to decreased life quality, severe complaints and death. Treatment for locally advanced, resectable rectal cancer improved over the years. Various chemotherapy protocols and combinations with radiation therapy and radical surgery - total mesorectal excision (TMA) - are the main elements of current therapy. Preoperative combined chemoradiation followed by surgery is the preferred treatment sequence. Radiation treatment in combination with fl uoropyrimidines (infusional 5-fl uorouracil [5-FU] or oral capecitabine) is recommended. Clinical trials with oxaliplatin-based neoadjuvant chemoradiation did not improve the pathologic complete response rate (pCR). Oxaliplatin-based treatment was more toxic as compared with 5-FU. The data concerning local recurrence rate and survival are controversial. Adjuvant chemotherapy in some studies improved survival, so - based on positive results in colon cancer - adjuvant FOLFOX chemotherapy may be recommended.]

[Oncological management of gastro-entero-pancreatic neuroendocrine neoplasias]

PETRÁNYI Ágota, UHLYARIK Andrea, RÁCZ Károly, BODOKY György

[Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are unusual and relatively rare neoplasms. They characteristically synthetize, store and secrete a variety of peptides and neuroamines, which can lead to development of disctinct clinical syndromes. Clinical symptoms and presentations vary depending on the location and hormones produced by the tumor. The diagnosis of NETs is established by histological examination and the immunohistochemical detection of general neuroendocrine markers, such as chromogranin A (CgA) and synaptophysin. An update of the WHO classifi cation has resulted in a new classifi cation dividing neuroendocrine neoplasms into neuroendocrine tumors (NETs) including G1 (Ki67 index ≤2%) and G2 (Ki67 index 3-20%) tumors and neuroendocrine carcinomas (NECs) with Ki67 index >20%, G3. The different available therapeutic approaches, including surgery, liver-directed ablative therapies, peptide receptor radionuclide therapy, and systemic hormonal, cytotoxic or targeted therapy, are discussed in this overview.]
