[The interstitial lung diseases (ILD) are a heterogeneous group of disorders that are classifi ed together because of similar clinical, radiographic or pathologic manifestation. The diffuse interstitial lung diseases are divided into those that are associated with known causes and that are idiopathic. The treatment choices and prognosis vary among the different causes and types of ILD, so the early and correct diagnosis is important. In oncology ILD could be a rather severe adverse effect of treatment with radiationor chemotherapy.]

[Signaling pathways in cancer stem cells (Notch, Hedgehog, Wnt)]


[OThe key regulators in the embryonic life, and later in the differentiation of tissues and organs are the evolutionary reserved signalling pathways, as Notch, Hedgehog and Wnt. Mutations of these pathways have been identifi ed in many tumor types, increasing the risk to the appearance of cancer stem cells (CSC), with very similar geno- and phenotype as normal stem cells have. Such CSCs with stemness functions can be developed not only from normal stem cells, but also from progenitor and differentiated cells. The main characteristics of CSC are the self maintenance, slow growth rate, very effective DNA-repair system, etc. All of these can contribute to the resistance. Further problems are the low number of CSC in the whole tumor mass, which makes rather diffi cult to achieve the effective drug concentration in CSC. The mentioned ancient pathways interact with many other pathways to form a network, which can infl uence the strategy of therapy. No doubt, that these pathways are promising targets, however, till now the clinical effectiveness is very low due to some reasons mentioned above. Nevertheless, some drugs are already in clinical use, either as monotherapy or part of the combinations. Little is known about the relationship between the pathways and the microenvironment, which has an outstanding role in the cellular activities, sometimes resulting opposite output. It is a great challenge to design effective drugs against CSC, similarly to fi nd reliable predictive biomarkers, which unfortunately still missing, since a reasonable drug-marker interactions would speed up the personalized treatment.]

[Why don’t immune checkpoint inhibitors work in colorectal cancer?]

SHI Yuequan, ZOU Zifang, KERR David

[In recent years, immune checkpoint inhibitors have been shown to be effective in treating manifold types of cancer but less robust in colorectal cancer (CRC). While, the subgroup of CRC with microsatellite instability (MSI; also termed as mismatch repair defi cient) showed a moderate response to Pembrolizumab in a single arm phase II clinical trial, microsatellite stable (MSS) cancers were unresponsive. Possible mechanisms that affect immune response in colorectal cancer will be reviewed in this article. We will also propose that histone deacetylase (HDAC) inhibition may reverse the immune editing commonly seen in advanced CRC and render them sensitive to immune checkpoint blockade.]

[Paleo-oncology - messages from the past]

[Nowadays, cancer is one of the greatest challenges facing mankind. However, there is still no consensus among researchers regarding the antiquity of cancer. Written sources and paleo-oncological studies may help to answer this question. The aim of this study is to present data on the history of cancer based on historical sources, literature data and own research fi ndings. Early historical sources indicate that cancer was already known in antiquity. Paleopathological studies of animal and human fossils show that malignant bone tumors were present in ancient times, although the frequency of the disease was seemingly very low. The increasing number of unearthed fossils and the use of modern diagnostic tools have led to a rise of the number of diagnosed cancer cases. Our comprehensive paleo-oncological study, focusing on the occurrence and frequency change of malignant tumors in historic populations of Hungary was based on the analysis of skeletal remains belonging to 11,000 individuals dated from the Early Neolithic to the late medieval period. During the analysis macromorphological, modern imaging and histological methods were applied. As a result of the extensive investigations osteological evidences of malignant bone tumors were identifi ed in 39 cases. Neoplastic bone diseases were present in all studied historical periods and there were no differences in their occurrence and frequency between the different archaeological periods.]

[Multidisciplinarity and pulmonary hypertension in idiopathic pulmonary fibrosis]


[Idiopathic pulmonary fibrosis (IPF) is a subgroup of the fibrotising idiopathic interstitial pneumonias occuring primarily in older adults. It is characterised by progressive decline of lung function and is associated with high mortality. IPF is frequently associated with pulmonary hypertension (PH). PH has unfavourable impact on the prognosis of IPF. PH should be suspected in IPF patients presenting with dyspnoe, desaturation on exertion and disproportionately low diffusion capacity. Transthoracic echocardiography is used to screen for PH in IPF patients. Although right heart catheterization is the gold standard procedure for the diagnosis of PH, this is not regularly performed on IPF patients. Chest high resolution computer tomography (HRCT) is essential for the diagnosis of IPF. IPF is typically characterised by the presence of usual interstitial pneumonia (UIP) pattern on HRCT. Multidisciplinary discussion bet­ween experienced pulmonologists, radiologists, and pathologists is key in the early and accurate diagnosis of IPF. An important role of the interstitial lung disease-multidisciplinary team (ILD-MDT) is to determine whether other diagnostic examinations and surgical lung biopsy is needed, in an attempt to reduce unnecessary risk. ILD-MDT should propose the initiation of antifibrotic therapies that have the potential to reduce disease progression. All patients diagnosed with IPF, with no contraindications for lung transplantation, should be referred early to a transplant committee.]

Delirium is a syndrome frequently encountered in intensive care and associated with a poor prognosis. Intensive care delirium is mostly based on general and palliative intensive care data in the literature. In this study, we aimed to investigate the incidence of delirium in coronary intensive care unit (CICU), related factors, its relationship with inhospital and follow up prognosis, incidence of age-related delirium and its effect on outcomes. This study was conducted with patients hospitalized in CICU of a tertiary university hospital between 01 August 2017 and 01 August 2018. Files of all patients were examined in details, and demographic, clinic and laboratory parameters were recorded. Patients confirmed with psychiatry consultation were included in the groups of patients who developed delirium. Patients were divided into groups with and without delirium developed, and baseline features, inhospital and follow up prognoses were investigated. In addition, patients were divided into four groups as <65 years old, 65-75 yo, 75-84 yo and> 85 yo, and the incidence of delirium, related factors and prognoses were compared among these groups. A total of 1108 patients (mean age: 64.4 ± 13.9 years; 66% men) who were followed in the intensive care unit with variable indications were included in the study. Of all patients 11.1% developed delirium in the CICU. Patients who developed delirium were older, comorbidities were more frequent, and these patients showed increased inflammation findings, and significant increase in inhospital mortality compared to those who did not develop delirium (p<0.05). At median 9-month follow up period, rehospitalization, reinfarction, cognitive dysfunction, initiation of psychiatric therapy and mortality were significantly higher in the delirium group (p<0.05). When patients who developed delirium were divided into four groups by age and analyzed, incidence of delirium and mortality rate in delirium group were significantly increased by age (p<0.05). Development of delirium in coronary intensive care unit is associated with increased inhospital and follow up morbidity and mortality. Delirium is more commonly seen in geriatric patients and those with comorbidity, and is associated with a poorer prognosis. High-risk patients should be more carefully monitored for the risk of delirium.
