[Treatment of head and neck cancer]


DECEMBER 10, 2018

Clinical Oncology - 2018;5(04)

[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.]

[Advancing therapies in metastatic castration-resistant prostate cancer]

GIULIA Baciarello, MARCO Gicci, KARIM Fizazi

[Introduction: Prostate cancer is the second most common cause of cancer world wide and is the most frequently detected cancer in the European Union in men over 50 years of age. Androgen deprivation therapy remains the corner stone of treatment for recurrent or metastatic disease. Unfortunately, nearly all patients will develop resistance to androgen blockade leading to castration-resistant prostate cancer (CRPC). Over the last 10 years, new treatment shaved ramatically improved overall survival of men with mCRPC. Current therapies are basedon AR-axis inhibitors and taxane-based chemotherapies, aswell as radiopharmaceuticals and Sipuleucel T. Areas covered: The authors provide a review of the current fi eld of systemic therapy in metastatic CRPC. This is followed by an in-depth analysis of recent developments in treatment, and the biological rationale behind these therapies. Expert opinion: Since several trials with docetaxel or novel hormonal agents showed improvement in overall survival in metastatic castration-sensitive prostate cancer, aswell as in non-metastatic castrationresistant patients, it is expected that a growing subgroup of patients will be expose dearlierto chemotherapy and to AR targeted agents. It becomes then fundamental to fi nd novel strategies to over come drug resistance and further improve survival.]

[PI3K–AKT–mTOR pathway as a therapeutic target]


[The PI3K-AKT-mTOR is one of the most busy signalling pathway, accepting and sending the message to the effector compartment. The pathway is very complex with activators (see the name), and inhibitors, as PTEN. Depending of the cell type this pathway participates in almost all functions of a given cell. The members of the pathway may have genetic failures, as a consequence, the risk for the development of different diseases, including cancer is high. Therefore it is logical to produce drugs to inhibit the dysregulated function. Unfortunately, despite the promising preclinical effectivity, so far only 4 drugs can be used to treat cancer patients. There are some hypothesis for the in effectivity, e.g. no useful marker for patient selection, high toxicity, false drivers for targeting. What is sure, combination therapy is much better than monotherapy]

[Medical use of marihuana especially in oncology]


[The medical use of marijuana has gained a considerable attention among wide range of cancer patients lately in Hungary. Consequently, oncologist sare facing questions related to cannabinoids more and more in their clinical practice. This article aims to clarify some basic concepts and to give a brief introduction on the current international and national legislation on their accessibility. Numerous publications have dealt with the application of marijuana in various indications. Among the tumour related indications, the concerned studies mainly refer to chemotherapy induced nausea and vomiting, chronic pain, sleep disorders, anorexia and cachexia. The article also to uches upon on knowledge connected to the causal treatment of malignant tumours, which are currently limited to glioblastoma. Information on the carcinogenic potential of cannabis and information on the popularity and attitudes of American oncologists can be found in this article. This paper gives a literature review in the above mentioned themes.]

Long-term follow-up results of concomitant chemoradiotherapy followed by adjuvant temozolomide therapy for glioblastoma multiforme patients. The importance of MRI information in survival: Single-center experience

LUKÁCS Gábor, TÓTH Zoltán, SIPOS Dávid, CSIMA Melinda, HADJIEV Janaki, BAJZIK Gábor, CSELIK Zsolt, SEMJÉN Dávid, REPA Imre, KOVÁCS Árpád

Introduction - Glioblastoma multiforme (GBM) is the most common malignant primary anomaly of central nervous system. The GBM infiltrates the nearly sturctures from the initial tumor and its metastatic attribution is well known. The aim of our single-centered retrospective study was to introduce the importance of postoperative medical imaging confirmation of total tumor resection for patient with GBM combined concomitant and adjuvant chemoradiotherapy on a 10 year long patient follow up. Methods - From January 2006 to April 2015 we registered 59 patients with newly diagnosed GBM at the University of Kaposvár Health Center Institute of Diagnostic Imaging and Radiation Oncology. The histological diagnosis was confirmed by a proficient neuropathologist (World Health Organisation WHO; grade IV astrocytoma). According to histological status if the ECOG performance status of patients allowed it the mutidisciplinary oncoteam recommended adjuvant chemoradiotherapy all features strictly by Stupp protocol. (60 Gy dose on the gross tumor volume and 2-3 cm margin for the clinical target volume with parallel 75 mg/m2 TMZ. Four weeks after monotherapial phase patients had to recieve 6 cycles of TMZ first cycle with 150 mg/m2 up to 200 mg/m2). The irradiation was carried out by a conformal three dimensional planning system. Results - 59 patients with the median age of 63 (range 17-84) year. Our sample counted 34 male patients and 25 woman patients. 14 patients underwent gross total tumor resection while, 39 patients underwent partial resection and the rest from our sample 6 patients passed through biopsy. Statistical analysis showed a lengthier survival among males than females, with a median survival of 13 months for males and females, the OS of 26.209 for males, meanwhile 15.625 for females. However, the difference is not considerable (log-rank p=0.203). Our study found that the estimated survival of patients at least 50 years old is significantly shorter at a median survival of 12 months (log rank p=0.027) than that of patients below 50 years of age at a median survival of 23 months. The longest estimated median survival was calculated with patients of ECOG '0' condition (16 months). However, no significant difference was found in the estimated survival of patients of different ECOG conditions (log-rank p=0.146). Based on the extent of surgery, complete resection resulted in the longest average survival of 36.4 months, followed by 21.5 months among patients with biopsy, and 15.8 months among patients with partial resection. Different surgical procedures, however, did not result in significant differences in survival (log-rank p=0.059). The overal survival of patients who had complete resection confirmed by MRI compared with the overal survival of patients with residual tumor confirmed by MRI as well we can estimate that there is significant difference between these two groups (p=0,004). Conclusion - Despite complex and intense treatment, recurrence is inevitable and causes relatively rapid death. In our analysis complete resection, as defined from the neurosurgeon’s report and postoperative MRI, resulted in an independently significant improvement in OS. Our results are the evidences that the treatment of patients with glioblastoma multiforme in Hungary is at least on the same level as any other developed European countries.

Attitude of spine surgeons towards the application of 3D technologies - a survey of AOSpine members

ÉLTES Endre Péter, KISS László, BARTOS Márton, EÖSZE Zsolt, SZÖVÉRFI Zsolt, VARGA Pál Péter, LAZÁRI Áron

Background - 3D technologies (3D virtual and physical model, 3D printing, computer aided engineering, finite element analysis based simulations) play an important role in personalized spine surgery. Objective - In collaboration with AOSpine a global, online survey-based study was performed in order to determine the acceptance rate and the factors which stand against the wider spread of 3D technologies. Methods - A survey containing 21 questions was developed and divided into five pages, every page corresponding to one chapter. Our analysis is based on the responses of 282 spine surgeons from 57 countries. To interpret our results in a global context, we used the Human Development Index of the respondent's countries in comparisons. Results - Significant difference between the AOSpine regions (p ≤ 0.05) was found, with the highest acceptance in Asia-Pacific region. There was no significant difference in acceptance score according to the field of spine surgery, or the surgical experience in years (p=0.77, and p=0.19). In the case of public practice, we found significantly higher acceptance compared to private and mixed (public and private) surgical practice (p ≤ 0.05). The acceptance of the technology varied based on the respondent’s resident country’s Human Development Index and was significantly different between „Medium” vs “Very high” (p = 0.0005) and „High” vs „Very high” (p=0.019) category. Significant positive correlation was found between the acceptance score and the HDI score (Spearman test, ρ = 0.37, p = 0.007). The main limitation factor was identified as the lack of information. Conclusion - There is high interest among spine surgeons towards the incorporation of 3D technologies into the clinical practice. Education, the healthcare system, and the economic environment plays a major role in acceptance. Our results provide the basis of a strategy to promote the application of 3D technologies.

TAJTI Jr. János, LÁTOS Melinda, ÁBRAHÁM Szabolcs, SIMONKA Zsolt, PASZT Attila, LÁZÁR György

[Background and purpose - Tension-type headache is a very common disease with a high socio-economic impact as its lifetime prevalence is 30-78% in the general population. The incidence of inflammatory bowel diseases is continuously rising. Limited data are accessible on quality of life in patients with surgically treated ulcerative colitis. The aim of our study is to examine quality of life, concerning headache, among patients who had undergone surgery due to ulcerative colitis. Methods - Between 1 January 2005 and 1 March 2016, surgery was performed due to ulcerative colitis in 75 patients. During this retrospective analysis the average duration of the follow-up was 46 (1-124) months. The pre-sence of headache was evaluated by the use of Brief Illness Perception and Headache Questionnaires. Results - Among the primary headache disorders (n=27), tension-type headache occurred in 19 (70.4%) cases, and 8 (29.6%) patients had migraine (without aura). Among tension-type headache cases 17 (89.5%) patients experienced episodic form and 2 (10.5%) suffered from chronic form. Patients with headache had obtained a significantly higher score on Brief Illness Perception Questionnaire. Conclusions - According to our study tension-type headache is common among patients with ulcerative colitis. This observation raises the question whether stress plays role in the pathogenesis of both diseases, which influences and worsens considerably quality of life. Neurological examination, psychological and psychiatric guidance are worth considering in patients with ulcerative colitis.]

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.
