[CHANGING STRATEGY IN THE LONG-TERM TREATMENT OF OVARIAN CANCER - ON THE IMPORTANCE OF PLATINUM-FREE INTERVAL]

[It was during the last 15 years when justified by clinical studies the sensitivity/resistance to anticancer chemotherapy was included in the setting of the prognostic factors of the ovarian cancer, while demonstrating a stronger correlation with the outcome than those factors known before. Remission and duration of remission after first-line chemotherapy are the two important components of sensitivity and their combinations measure its grade in a semi-quantitative manner. The chemotherapy sensitivity/resistance approach is based on the observations on ovarian cancer patients treated with platinum based chemotherapy. This agent in repeated adminstrations during the whole course of the disease is still a decisive component of the ovarian cancer chemotherapy. As a consequence there is always “a platinum-free interval”. The prolongation of this platinum-free interval with non-platinum chemotherapy has the potencial of increasing the remission and survival by platinum reinduction administered in the third-line of chemotherapy. In spite of the facts mentioned above, there are centers which prefer the early re-administration of taxan/platinum combination to the prolongation of platinum- free interval and expose their patients to an elevated risk of cumulative, in the first-line non-haematological toxicity.The neurotoxicity can deteriorate the quality of life and the parenchymal laesion of kidneys can prevent further chemotherpy.]

[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.]

[Recent strategies in the chemoterapy of soft tissue tumors]

PÁPAI Zsuzsanna, KISS Nóra

[Conventional adjuvant therapy is, in most cases, either the well-known standard doxorubicin monotherapy or the combination of doxorubicin + ifosfamide. No clear guideline has been developed yet - adjuvant therapy is recommended in cases with high grade, larger than 10 cm, sarcoma, where surgery hasn’t been suffi ciently radical, and adjuvant radiotherapy may not be advisable. In locally advanced tumors, due to the requirements of limb salvage, isolated limb perfusion is recommended. As a new compound, hafnium-oxide nanoparticles (NBTXR3) can be useful in local therapy: combining intratumoral injection and radiotherapy may be a fl agship initiative, however further investigations are necessary. In the treatment of metastatic tumors, beside the standard methods, new, targeted treatments are becoming more and more prevalent: in leiomyosarcomas trabectedine, pazopanib and olaratumab; in liposarcomas trabectedine and eribulin; in synovial sarcomas pazopanib; and in imatinib-resistant GIST, sunitinib and regorafenib. Soft tissue sarcomas are rare tumors categorized as heterogeneous histological subtypes. In their treatment, it is key to customize the treatment based on these subtypes and interdisciplinary collaboration with the orthopedic surgeon, the pathologist and the radiotherapist to determine the suitable therapy for each individual.]
