[Current strategy in the surgical treatment of abdominal hematogenous metastases]


FEBRUARY 10, 2015

Clinical Oncology - 2015;2(01)

[The cornerstone of the therapy of most tumors is still the resecability of the primary tumor: if the cancer can be removed, the chance for recovery will signifi cantly increase. The development of the complex oncologic therapy lead also to the headway of metastasis surgery that used to be a rarity few decades ago. Based on the fi ndings of recent molecular genetic research and multimodular oncologic treatment it was found in more and more tumors that the removal of their metastasis shows benefi t for patients with advanced disease. In order to operate metastatic disease successfully extensive surgical experience and the knowledge of the tumors biologic behavior are required. Thus, the continuous interdisciplinary cooperation and the role of the oncoteam are essential to correct therapeutic decisions. In this review we discuss the possible surgical interventions of abdominal hematogenous metastases of different tumors.]

[Molecular diagnostics of brain tumors - an up-date]


[In recent years there have been major advancements in the understanding of molecular events driving brain tumor genesis and progression. Although state-of-the-art techniques are not widely available, many of the molecular discoveries lead to novel antibodies that can assist in identifying the major molecular subgroups by immunohistochemistry. Molecular informations will likely be incorporated into the next World Health Organization (WHO) classifi cation of central nervous system tumors, but clinical practice in many centres have already taken on the available informations and therapeutic decisions are made based on genetic/epigenetic information. In the adult population IDH, ATRX and 1p/19q codeletion studies help to defi ne molecular subgroups that correlate better with prognosis and therapeutic response than traditional histology based diagnosis. The KIAA1549-BRAF fusion gene is a hallmark for pilocytic astrocytomas, while diffuse pediatric gliomas lack the IDH mutations and 1p/19q codeletions that are common in adult astrocytomas and oligodendrogliomas. Uncommon in adults, Histone H3.3 mutations are pathognomic in pediatric brainstem malignant gliomas. Molecular subgroups of medulloblastomas have also been identifi ed, and a corresponding set of antibodies are ready to guide treatment decisions in those centres where molecular techniques are not available. These genetic and epigenetic events determine a tumor’s behaviour, and integrating this level of informations into neuropathology practice is essential to provide the best possible care to both pediatric and adult patients.]

[Neoadjuvant treatment of rectal cancer]


[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.]

[Treatments of brain tumors in adults – an up-date]

BAGÓ Attila György

[The prognosis of brain metastases is very poor. Surgery and radiotherapy provides the fi rst line treatment, while systemic therapy has limited value. Nevertheless, our knowledge is increasing: normal cells contribute signifi cantly to the homing and growth of tumor cells; the molecular profi le of the primary tumor and its metastases could be different, which infl uences the therapeutic strategies; the type of blood supply can change during the tumor growth. It would be very important to optimize the cooperation of the different therapeutic modalities, and to fi nd markers which could predict the risk of metastatization.]

[Development in the treatment of non-operable, metastatic colorectal cancer]

GRAMONT de Aimery

[Today, due to the steady improvement, the survival of patients with non-operable, metastasic colorectal cancer is about 30 months. This review discusses the results of recent clinical trials, the new drugs, the treatment protocols as well as the tumor response after surgery. A suggestion will be made not only on an optimal treament strategy, but also how to increase the survival, and the feasibility of a secunder resection.]

[Psychooncology in the everyday practice]


[In the past 40 years the progressively growing fi eld of psychooncology has played an increasing role in the multidisciplinary practice of oncology. In this review methods for identifying and treating cancer patients’ psychological challenges will be summarized. Effective psychological interventiones will be discussed, and two methods especially devised for supporting cancer patients (Simonton Training and Mindfulness Based Cancer Recovery) will be introduced. We also deal with the communication traits that affect the doctor-patient relationship, the mental challenges that affect doctors dealing with terminally ill patients, burnout and its prophylaxis.]

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.

[Treatment of head and neck cancer]


[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.]

[Symptomatic subependymomas of the ventricles. Review of twenty consecutive cases]


[Background and purpose - Intraventricular subependymomas are rare benign tumors, which are often misdiagnosed as ependymomas. To review the clinicopathological features of subependymomas. Patient selection and methods - Retrospective clinical analysis of intraventricular subependymomas and systematic review of histological slides operated on at our center between 1985 and 2005. Results - Twenty subependymomas presented at the median age of 50 years (range 19-77). Two (10%) were found in the third, three (15%) in the forth, and 15 in the lateral ventricles. There was male preponderance (12 vs. 8). Ataxia (n=13) and papilledema (n=7) were the most common clinical presentations. Fifteen patients underwent gross total resection, and five had subtotal resection. None of the cases showed mitotic figures, vascular endothelial proliferation or necrosis. Cell proliferation marker MIB-1 activity (percentage of positive staining tumor cells) ranged from 0 to 1.4% (mean 0.3). Two cases were treated with preoperative radiation therapy (50 Gy) before the CT era, three other patients received postoperative radiation therapy for tumors originally diagnosed histologically as low grade ependymomas. Three patients (15%) died of surgical complication between one and three months postoperatively, and three patients died of unrelated causes in eight, 26 and 110 months. Fifteen patients were alive without evidence of tumor recurrence at a median follow-up time of 10 years. Conclusion - Subependymomas are low-grade lesions and patients do well without adjuvant radiotherapy. Small samples from more cellular areas may be confused with low grade ependymomas, and unnecessary radiotherapy may follow. Recurrences, rapid growth rates should warrant histological review, as hypocellular areas of ependymomas may also be a source of confusion.]

[Nutritional status, realizing sarcopenia and the importance of prehabilitation in surgical departments]

CSIBA Borbála, NAGY Ákos, LUKOVICH Péter, BAROK Bianka

[INTRODUCTION - Malnutrition can significantly influence the surgery’s outcomes. Currently, patients risk grouping is based on the body mass index (BMI), and the preparation for surgery is concerned only as nut­rients administration. PATIENTS AND METHODS - The Nutrition Support Team established in our Department is assessing first the patients’ nutritional status (BMI, MUST), sarcopenia (skinfold measure, handgrip strength) and fitness status (6 min step test, sit to stand test). Risk group patients were suggested nutrients and physiotherapy prior to the surgical operation. In order to follow up our patients we created an online interface and repeated the tests immediately before the operation. RESULTS - 135 cancer patients (76 male and 59 female) were operated. Their average age was 69.6 years. 33 patients had weight loss before the first consultation (average=8.7 kg). Their average BMI was 26.3. 21 patients had gained weight in the last 6 months (average=7.8 kg). Patients with left descending colon, liver - and also pancreatic tumors had overweight BMI values while the rest of pa­tients ill with right colon and stomach neo­plasm had normal weight. Those patients who we enrolled to the online system had better results at the second assessment. CONCLUSIONS - According to our survey, most of the patients had overweight BMI values but had sarcopenia based on anthropometric tests. Therefore, the importance of in time recognized and preoperatively started nutritional therapy must be coupled with the parallel applied physiotherapy. ]
