Background:Standard treatment of glioblastoma multiforme consists of postoperative radiochemotherapy with temozolomide, followed by a 6-month chemotherapy. Serious hematologic complications are rarely reported.Case Report and Results:The authors present the case of a 61-year-old female patient with glioblastoma multiforme treated with external-beam radiation therapy and concomitant temozolomide. After completion of treatment, the patient developed symptoms of serious aplastic anemia that eventually led to death due to prolonged neutro- and thrombocytopenia followed by infectious complications.Conclusion:Lethal complications following temozolomide are, per se, extremely rare, however, a total of four other cases of aplastic anemia have been reported in the literature so far.ZusammenfassungHintergrund:Die Standardbehandlung des Glioblastoma multiforme ist die postoperative Radiochemotherapie mit Temozolomid, gefolgt von einer 6-monatigen Erhaltungschemotherapie. Schwerwiegende hämatologische Toxizitäten werden selten berichtet.Fallbericht und Ergebnisse:Die Autoren präsentieren den Fall einer 61-jahrigen Patientin mit Glioblastoma multiforme, die mit externer Strahlentherapie und begleitender Temozolomidchemotherapie in Standarddosierung behandelt wurde. Nach Abschluss der Behandlung zeigte die Patientin Symptome einer schweren aplastischen Anämie, die infolge prolongierter Neutro- und Thrombopenie durch infektiöse Komplikationen zum Tode führte.Schlussfolgerung:Letale Komplikationen einer Temozolomidchemotherapie sind selten, bislang wurden insgesamt vier Fälle einer aplastischen Anämie in der Literatur berichtet.

Recently, new drugs targeting the immune system have been introduced to the standard care of metastatic malignant melanoma. One of these immunomodulatory drugs is ipilimumab, a fully human monoclonal antibody that blocks cytotoxic T-lymphocyte antigen-4. The following case reports on a 54-year-old man with metastatic melanoma, who developed Grade 4 thrombocytopenia during treatment with ipilimumab already after first dose. Bone marrow examination confirmed a diagnosis of drug-induced, immune-mediated thrombocytopenia. Isolated thrombocytopenia has rarely been associated with ipilimumab and there is no standard treatment algorithm of such complication. This case demonstrates the importance of monitoring full blood count in all patients receiving ipilimumab and suggests a possible treatment algorithm.

Secondary tumors of the ovary account for 10–25% of all ovarian malignancies. The most common tumors that give rise to ovarian metastases include breast, colorectal, endometrial, stomach, and appendix cancer. The correct diagnosis of secondary ovarian tumors may be challenging as they are not infrequently misdiagnosed as primary ovarian cancer, particularly in the case of mucinous adenocarcinomas. The distinction from the latter is essential, as it requires different treatment. Immunohistochemistry plays an important role in distinguishing primary ovarian tumors from extra-ovarian metastases and, furthermore, may suggest the primary tumor site. Despite extensive study, some cases remain equivocal even after assessing a broad spectrum of antigens. Therefore, gene expression profiling represents an approach able to further discriminate equivocal findings, and one that has been proven effective in determining the origin of cancer of unknown primary site. The available data concerning secondary ovarian tumors is rather limited owing to the relative heterogeneity of this group and the practical absence of any prospective trials. However, several intriguing questions are encountered in daily practice, including rational diagnostic workup, the role of cytoreductive surgery, and consequent adjuvant chemotherapy. This review seeks to address these issues comprehensively and summarize current knowledge on the epidemiology, pathogenesis, and management of secondary ovarian tumors, including further discussion on the different pathways of metastatisation, metastatic organotropism, and their possible molecular mechanisms.

Microsatellite instability (MSI) and mismatch repair deficiency are an emerging issue in oncology and molecular pathology. Besides being associated with better clinical outcome in colon cancer, MSI also harbors the potential to predict response to chemotherapy and immunotherapy. MSI was also observed in other solid tumors, including endometrial cancer, ovarian cancer, and melanoma, besides colon cancer. Strong evidence shows that MSI is a frequent event in melanoma. However, the data on MSI prevalence, pathogenesis, and clinical consequences in melanoma are limited. Therefore, we summarize the current knowledge on MSI in melanoma and outline future perspectives and clinical implications, including its role as a prognostic and/or a predictive factor.

Background: Mesothelioma of the tunica vaginalis testis is a rare and aggressive cancer; fewer than 90 cases have been reported. It occurs in all age groups, but its highest incidence appears between 55 and 75 years of age. Less than 5% of all malignant mesotheliomas arise from the tunica vaginalis testis. Case Report: The authors present a rare case of localized malignant mesothelioma of the tunica vaginalis testis. Diagnosis and treatment are described. Conclusion: Mesothelioma of the tunica vaginalis testis can be asymptomatic for a long time. In more than half of the cases, the clinical manifestations imitate a hydrocele or a tumor mass in the scrotum. Despite treatment, this tumor has a very poor prognosis with a median survival of 23 months.

BACKGROUND Annually, more than 27,000 persons die of cancer in the Czech Republic. It is known that in addition to the demographic aging of the Czech population, the cancer burden is increased. AIM These data clearly demonstrate the need for affordable and good follow-up care for patients, especially for older patients and/or patients with no other cancer treatment due to irreversible progression of tumor. MATERIALS AND METHODS We are talking about so-called palliative cancer care, which can be provided at different levels. One of the most common forms of palliative cancer care is hospice care. RESULTS Our clinic in the years 2008-2010 received a total of 446 patients. 288 of them were women and 158 men. The average age of women was 61 years (age range 20-81 years). The average age of men was 56 years (age range 18-96 years). The performance status was in the fitness category PS-0 (8%), PS-1 (54%), PS-2 (33%) and PS-3 (5%). CONCLUSION Currently the outpatient palliative cancer care are coming more into the forefront. This type of care allows patients to stay as long as possible at home among their close relatives. Prerequisite for a well working outpatient palliative care is cooperation with general practitioners and home health care agencies.

BackgroundGreat progress has recently been made in the treatment of metastatic renal cell carcinoma, including the introduction of nivolumab, an immune checkpoint inhibitor. Despite promising results, this treatment brings a completely new spectrum of adverse events, distinct from those experienced with small-molecule kinase inhibitors. Neurologic immune-related adverse events may be serious and potentially life-threatening complications requiring immediate immunosuppressive therapy. Only a few cases of immune-related encephalitis induced by checkpoint inhibitors have been described and the data regarding the management of this serious adverse event are limited.Case presentationWe report the case of a 63-year-old white man with metastatic renal cancer who developed severe chorea-like dyskinesia during nivolumab therapy. The findings on brain magnetic resonance imaging and flow cytometry of cerebrospinal fluid, and the positivity of anti-paraneoplastic antigen Ma2 immunoglobuline G class autoantibodies were consistent with a diagnosis of immune-related encephalitis. High-dose intravenous corticosteroid therapy was started immediately, with no signs of improvement, even when infliximab was added. Our patient refused further hospitalization and was discharged. Three weeks later, he presented with signs of severe urosepsis. Despite intensive treatment, he died 4 days after admission.ConclusionsThe management of less frequent immune-related adverse events has not been fully established and more information is required to provide uniform recommendations. Immune-related encephalitis is a severe and potentially fatal complication requiring immediate hospital admission and extensive immunosuppressive therapy. The examination of cerebrospinal fluid for paraneoplastic antibodies, such as anti-N-methyl-D-aspartate receptor and anti-Ma2 antibodies, in order to distinguish autoimmune etiology from other possible causes is essential and highly recommended.

BACKGROUND Metastatic malignant melanoma belongs to a group of cancers with high mortality. In recent years, advances in our knowledge of the pathogenesis of melanoma and the discovery of new drugs has resulted in significant progress in the treatment of metastatic malignant melanoma patients. The development of resistance to these drugs, however, remains a challenge. One way how to avoid resistance, or at least delay it, is to administer combination therapy. OBSERVATION AND CONCLUSION This case study demonstrates that combination therapy with a BRAF and a MEK inhibitor can be used to successfully treat metastatic malignant melanoma patients and suggests they should be employed in therapeutic algorithms for patients with metastatic malignant melanoma and BRAF gene mutations.

INTRODUCTION Annually more than 27,000 persons die of cancer in the Czech Republic and the overall incidence of malignancies is still increasing. These data shows the need for affordable and good follow-up care especially for patients without any cancer treatment due to irreversible progression of tumor. Currently the outpatient palliative cancer care gets more into the forefront. Prerequisite for a well working outpatient palliative care is cooperation with general practitioners and home health care agencies. The purpose of the so called program of palliative cancer care is to guide a patient in palliative cancer care and to improve the cooperation among health care providers. METHODS During the period from January 2008 to October 2010 we evaluated in patient without any oncology treatment due to irreversible progression of tumor. RESULTS In palliative outpatient clinic we treated 446 patients, 119 of them received home care services with average length of 27.8 days. 77 patients died at home, 51 in health facilities and 41 in inpatient hospice care. CONCLUSION We present pilot study focusing on outpatient palliative cancer care which shows the real benefit from early indication of palliative cancer care. This type of care allows patients to stay as long as possible at home among their close relatives.
