[First-line treatment of epithelial ovarian cancer]


FEBRUARY 20, 2014

Clinical Oncology - 2014;1(01)

[The restructuration of Hungarian oncological attendance and medicinal fi nancing resulted in the more intensive participation of clinical oncologists in the therapy of patients with ovarian cancer. The aim of the authors was not to defi ne the taxative therapeutic recommendations, but to give an overview on the development of the therapy and to introduce the deliberation aspects and therapeutic alternatives. While the primary and secondary prevention have developed in case of cervical cancer - with the possibility of eradication - the improvement of surgical techniques and clinical oncological treatments may result in the decrease of mortality in ovarian cancer. It is important to emphasis that only the appropriately aligned application of the two therapeutic modalities can lead to the desired outcome. It has become clear by the end of the ‘90s, that paclitaxel-carboplatin combination is the standard chemotherapy against ovarian cancer. Alternative cytostatic treatments like intraperitoneal treatment and triplets were not breakthroughs. The dose intensive treatment increased the survival rates besides good tolerability, however the results require further confi rmation. Neoadjuvant therapy should be considered in case of patients with advanced and metastatic disease in selected cases. Recently, therapeutic use of angiogenesis inhibition comes with signifi cant improvement. Bevacizumab is the fi rst of targeted therapies, and studies on the effectiveness of similar compounds are under way.]

[How long the colorectal cancer should be treated?]


[Colorectal cancer is one of the leading cancer-related death worldwide. The optimal treatment duration of metastatic colorectal cancer depends on the individual treatment aim and it should be decided by an onco-team and by the patient. In this review several actual issues will be discussed, like the optimal duration of therapy to reach the secondary resection, the accepted response rate and best treatment strategy in case of non-operable colorectal cancer. Furthermore, emphasis is given to the most useful endpoints to evaluate different therapeutic approaches.]

[Management of febrile neutropenia in the oncological practice]


[Febrile neutropenia is one of the most feared complications of anti-tumor therapy. It can either herald potentially fatal infection or contribute to suboptimal dose-intensity of cancer treatment. Optimal management of affected patients is based upon a multi-disciplinary approach dependent on several factors. Knowledge on institutional epidemiology and predefi ned management strategies improve quality and outcome of anti-infective therapy. In an era of more and more resistant pathogens and erosion of the antimicrobial armamentarium clinicians taking care of cancer patients carry increased responsibility in their professional activity. Here questions of practical importance related to prevention and therapy of neutropenic infections are outlined.]

[Management of pancreatic cancer today]


[Pancreatic cancer (PC) is a major health problem with a poor prognosis. The number of patients with PC is increasing globally. There are no screening tests for early detection of PC, but even when diagnosed early, surgery is possible in only a minority of cases. Managing PC remains a big challenge. For selected patients with borderline or unresectable disease, neoadjuvant therapy offers the potential for tumor downstaging. In patients with resectable disease, adjuvant chemotherapy improves the fi ve year survival rate, whereas the use of adjuvant radiochemotherapy is still controversial. In metastatic cancer, monotherapy with gemcitabine remained the main therapeutic option during more than 10 years. Many different combinations with other drugs and new targeted therapies have been tested with gemcitabine. Only a combination of erlotinib and gemcitabine has shown a modest survival benefi t until now. Many gene alterations that directly contribute to pancreas tumorigenesis have been identifi ed or are under active investigation. Recently, the FOLFIRINOX regimen has been reported to be more active than gemcitabine in selected metastatic patients. Quality of life is an extremly important factor, when treating a patient with PC. CA 19-9 serum level can provide important information with regards to prognosis, overall survival, and response to chemotherapy as well as predict post-operative recurrence. There is a strong need for other predictive biomarkers to select patients, who might benefi t from available and new therapeutic options.]

[Resistancy and/or progression - Failure or only a short stop]


[Nowadays, with the continuously in creasing demand for targeted diagnostics and therapy, we are approaching an ideal stage when the most effective treat ment for a given patient could be selected. However, some basic problems are still waiting to be solved. One major hurdle is the heterogeneity, the formation of subclones with different signifi cance during progression, but with the capacity to overgrow after the failure of the initial therapy. The importance of this phenomenon is refl ected in the daily practice where targeted therapy is allowed to treat only locally extended or metastatizing tumors. Therefore, it is not as to nishing, that the clinical success is usually tem po rary, the disease in spite of the good response at the beginning will progress. The main reason is the resistancy against the carefully analysed and applied therapeutic drugs, which has several options (e.g. new mutations, crosstalks between pathways, faults of feed-backs, etc.). This review focuses on the acquired resistancy with some relevant examples. Among the open questions we can recall e.g. the resistancy in combination therapy, or the suggested link between resistancy and progression including the potential use of drug rechallenge.]

[Aspiration cytology in tumor diagnostics]

JÁRAY Balázs

[Aspiration cytology (fi ne-needle aspiration, FNA) has increasing role in cancer diagnostics. The review briefl y introduces the relevant methods, their place in the clinical protocolls to identify the given lesions, emphasising advantages and disadvantages. An overview is given on the acceptance of FNA worldwide, and also in Hungary based on private experiences. In certain cases examples are summarized how FNA can contribute to the identifi cation of the diseases, with some important comments, such as the limitations of the method. Finally, the expected results are evaluated, together with the possibilities to optimalize the outcome.]

[Treatment of childhood tumors of mesenchymal origin]

CSÓKA Monika

[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.]

[Gynecological malignancies: review of the radiological diagnostics and image-guided therapy - Onco Update 2008]


[The recent results of diagnostical imaging of gynecological tumours and the actual place of interventional radiological methods are discussed. Systematical reviews of articles published during the last year (2007) have been availed to discuss: cervical cancer, endometrial cancer, ovarian cancer, general and special imaging of the female pelvis, different uterine fibroid ablation methods (embolisation and high-intensity focused ultrasound [HIFU]). Experience of gynecological tumour imaging is growing rapidly, therefore, even the current examination algorithm is changing continuously. New diagnostic and therapeutic modalities are making their way into the daily routine. Some examinations become obsolete during the course of time and thus their further application should be avoided. In the meanwhile, some modalities prove their worth and become indespensable during the investigation of a given pathology.]

[Treatment of testicular germ cell tumors – an up-date]

BAKI Márta

[The frequency of germ cell tumors is about 1% of all male cancers. The incidence increases in developed countries. The prevalence is the highest among the young males. The histologic type, extent of disease and therapy is based on international guidelines. The surgery, radio- and chemotherapy can achieve cure in the germ cell cancer patients. Regarding the late toxicity, the minimal invasive tumors are suggested to keep on the wait and see policy. The complex therapy of poor risk groups reached more than 80% permanent remission rate. The chemotherapy is based on cisplatin, but in second and third line therapy paclitaxel, gemcitabin and oxaliplatin is widely used. After the cure of germ cell cancer patients the careful follow up is mandatory.]

[Management of prostate cancer today]

PETRÁNYI Ágota Eszter, BODROGI István

[Although metastatic prostate cancer remains an incurable disease, the past years witnessed an extraordinary progress in the management of patients with castration resistant prostate cancer (CRPC). Development of novel agents that modulate the androgen receptor pathway, growth factor signaling pathways, immune functions and bone targeting machinery has been the focus of therapeutic strategies because of its signifi cance in the biology of prostate cancer progression. The arrival of several new agents — cabazitaxel, abiraterone acetate, enzalutamide, sipuleucel-T, denosumab and radium-223 — is changing the options and management of patients with metastatic castration resistant prostate cancer (mCRPC). Prostate cancer is a heterogeneous disease, therefore, in treatment must be considered the clinical characteristics of the disease as it manifests in an individual patient. The aim of this review is to summarize the most important new fi ndings for metastatic prostate cancers according to the different molecular pathways and to discuss their potential role on the management of this disease.]

[The clinical importance of HER2 expression in breast cancer]

KAHÁN Zsuzsanna

[HER2 (neu/c-erbB-2) is a member of the EGF receptor family. It is activated without binding a specific ligand that leads to malignant transformation and tumor progression. Overexpression of HER2 is detected in approximately one quarter of human breast cancers. Immunohistochemistry and in situ hybridization (FISH) are the most widely used techniques in studying HER2 expression. HER2 positivity indicates worse outcome in node positive breast cancer and increasing number of studies show unfavourable prognosis in node negative cases as well. Recent data indicate that the knowledge of HER2 status may promote therapeutic decision. The generally applied cyclophosphamide- methotrexate-5-fluorouracil (CMF) polychemotherapy seems to provide no benefit in HER2 positive cases in contrast with HER2 negative breast cancer patients. Interestingly, doseintensive doxorubicin based chemotherapy gives better results in HER2 positive than in HER2 negative tumors. Determination of HER2 expression has great importance before therapeutic application of the humanized antibody trastuzumab (Herceptin). HER2 overexpression usually correlates well with estrogen and progesterone receptor negativity and hormone-resistance, therefore hormonal therapy is not justified for these patients. Some experimental and clinical data indicate that in case of simultaneous HER2 and ER positivity tamoxifen worsens treatment results which may be prevented by the coadministration of tamoxifen and trastuzumab. Emerging experimental and clinical data about HER2 has led to a new stage of individual treatment of breast cancer patients. The knowledge of HER2 status promotes antitumor intervention based on molecular characteristics of breast cancers. Therefore, reliable HER2 tests are needed in the everyday practice.]
