Clinical Oncology - 2018;5(02)

[Although cancer immunotherapy was initiated by William Coley more than a century ago, the fi eld of cancer vaccines is in an early stage of development. Only recently, major advances in cellular and molecular immunology have allowed a comprehensive understanding of the interaction between the immune system and the tumor. Data from several preclinical and clinical trials have confi rmed the positive effect of the cancer vaccines which accompanied in several cases by positive clinical outcomes. In our article we try to discuss the new cancer vaccine strategies which are under development or in a clinical phase stage.]

[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.]

[Cardiotoxicity caused by fluoropirimides]

PIA Österlund

[One of the most effective traditional anticancer drugs are the fluoropyrimidines. The most challenging problem of the treatment is the cardiotoxicity. This review focuses on cardiotoxicity based on the references as well as personal experiences. The severness of the cardiotoxicity has a rang euptofatal outcome. There for eit is mandatory to monitor heart condition during the treatment with fluoropyrimidines.]

[Fusions in solid tumors]

KOPPER László

[Genetic fusions are the cosequence of genomic rearrangement including chromosomal inversion, interstitial deletion, duplication, amplifi cation, translocation. Fusions can influence tumor development and progression. Fusions fi rst discovered in hematological malignances (e.g. BCR-ABL), butlater more and more were identified dueto the higly sensitive NGS. It has been found that the oncogenic fusions are in minority in a given tumor. Today, some fusions were apprevedas targets (ALK, ROS1, PDGFB) by FDA. Asino ther targeted therapy resistance is in evitable, which is a very important challenge for newly designed drugs.]

[Tumor-associated neurological syndromes]

GORKA Eszter, FABÓ Dániel

[Tumor associate neurological symptoms are heterogeneous clinical entities with diverse etiologies, that may infl uence both the central, and peripheral neural system, as a primary or secondary tumor, may due to immune mediated processes. In our review, we summarize the neural syndromes frequently occurring in oncological practice. We focus on the most frequent neuronal tumors, the brain metastases, that are recently affected by the new targeted and immunotherapies showing increasing intracranial activities. We provide details on paraneoplastic neurological syndromes, because, in spite of their relatively rare occurrence, the modern diagnostic protocols may contribute to early diagnosis that are mandatory for detecting the underlying tumor. Finally we describe the neurological side effects of various oncotherapies, such as PD1 inhibitors, that are accompanied by 3% incidence of neurological complications, and chemotherapy related polyneuropathies. We provide support for anticonvulsive drug selection also, based on their drug-interaction profi le.]

[Pharmacological treatment of metastatic melanoma]

OLÁH Judit, GYULAI Rolland

[Malignant melanoma belongs to the group of relatively easily manageable tumors; if detected and removed early, it rarely metastasizes. Although the visible nature of the primary tumor provides opportunity for early diagnosis, there is a signifi cant portion of patients who receive proper management only with substantial delay. The fact that there are annually 300-400 patients with metastatic disease in Hungary, can be mostly attributed to public unawareness about melanoma, and consequent delay in seeking medical treatment. Metastatic melanoma remains - even today - an incurable disease. Molecular genetic research, however, resulted in revolutionary changes in melanoma management. Today, apart from the classic pathological prognostic factors, information regarding specifi c molecular modifi cations (such as in the expression of the BRAF, NRAS, c-KIT genes and proteins) are inevitable for the setting up of a personalized oncological treatment plan. By targeting members of the MAPK signal transmission pathway (using BRAF- and MEK-inhibitors), signifi cant improvement could be achieved in metastatic melanoma. Similarly, new drugs targeting specifi c immune checkpoint regulators (such as CTLA-4 and PD-1/PD-1L) provide previously unprecedented survival benefi t for melanoma patients. In this review the most recent developments in the fi eld of melanoma management are summarized.]

[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.]

[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.]

[Intravenous immunoglobulin immunotherapy in immune mediated habitual abortions]

FÜLÖP Vilmos, PETRÁNYI Győző

[INTRODUCTION - Based upon international and domestic research data authors summerize the humoral and cellular im­munregulatory disorders which can be found in the background of “immune me­diated abortions” (IMA). PATIENTS AND METHODS - Within the frame of a home research program a special examination protocol was elaborated in order to sepatare alloimmune habitual abortions from autoimmune and non immune backgrounds. After all other causes were excluded erythrocyte antibody inhibition assay (EAI) was used for measuring the serum level of FcgRII receptor blocking IgG antibody, because its lack an important diagnostic parameter. Among the cell mediated immunofuntional tests the mixed lymphocyte culture reaction (MLC) was the most useful. During the roughly last 16 years 67 out of 76 selected alloimmun IMA patients were administered Intratect IVIG treatment without any particular selection among them. IVIG treatment was first applied on the completed 5-6th week of pregnancy and doses of 0,3-0,4g/kg bodyweight per oc­casion were given 3 times with 3-week intervals. RESULTS - Altogether a significant rise in the serum level of blocking antibodies was shown after each IVIG treatment although a slight decrease was seen after every given dose. Of the 67 IMA patients 54 carried infants to term during the study period. In 4 cases of abortion no cause was identified with post hoc diagnosis. Thus the success rate of this type of IVIG therapy was 93.1% (58/54). Conclusion - In approprietly selected alloimmun IMA cases the IVIG generated immunoregulatory and antiimflammatory pathways may contribute to its net positive reproductive effect.]

[Treatment of head and neck cancer]

KATONA Csilla, LANDHERR László

[Head and neck cancers cause worldwide a signifi cant problem in health care systems. Despite great advances in therapeutic modalities its prognosis has not changed in the past few decades. It is mainly caused by classical risk factors, like alcohol consumption and smoking, but in a signifi cant number of oropharyngeal cancers HPV infection plays a major role, which is associated with a new patient group characterized by a much better prognosis and therapeutic response. In the diagnostic phase staging examinations (CT scan, MRI, FDG-PET) are also involved which are necessary to multidisciplinary decision making. It can be largely infl uenced by the patient’s preference. The therapy is based on multimodality approach; surgery, radiotherapy, chemoirradiation, chemotherapy and the combination of these are used in early or locally advanced tumours. Targeted agents like EGFR inhibitors are partly used in the recurrent/metastatic setting or in combination with radiotherapy. Immun checkpoint inhibitors are new therapeutic options for pretreated, recurrent/metastatic patients and their role is under investigation in earlier therapeutic lines. Several clinical trials aim treatment desintensifi cation strategies in HPV positive tumours. Molecular genetic tests try to defi ne subgroups of patients to plan individualized treatment. Regarding the signifi cant functional and aesthetic damage of both disease and treatment, supportive care and rehabilitation are of great importance.]
