    Abstract KRAS mutant lung cancer is the most prevalent molecular subclass of adenocarcinoma (LUAD), which is a heterogenous group depending on the mutation-type which affects not only the function of the oncogene but affects the biological behavior of the cancer as well. Furthermore, KRAS mutation affects radiation sensitivity but leads also to bevacizumab and bisphosphonate resistance as well. It was highly significant that allele specific irreversible inhibitors have been developed for the smoking associated G12C mutant KRAS (sotorasib and adagrasib). Based on trial data both sotorasib and adagrasib obtained conditional approval by FDA for the treatment of previously treated advanced LUAD. Similar to other target therapies, clinical administration of KRASG12C inhibitors (sotorasib and adagrasib) resulted in acquired resistance due to various genetic changes not only in KRAS but in other oncogenes as well. Recent clinical studies are aiming to increase the efficacy of G12C inhibitors by novel combination strategies.

    Title translation Molecular classification of pancreatic cancer.
    Abstract Pancreatic cancer is a malignancy with outstandingly poor prognosis caused by several factors among which one is that it is predominated by mutant KRAS oncogene. Genomic studies revealed that clinically useful therapy targets are present only in the DNA repair deficient subgroup and in the minor wild type KRAS-carrying group. However, phylogenetic studies defined four molecular subgroups of pancreatic cancer among which the immunogenic progenitor form could well be the target of immunotherapies. Furthermore, this group may well be the one characterized by DNA repair deficiency and high tumor mutational burden. Furthermore, the majority of familiar pancreatic cancers could also be found in this latter subgroup. Unfortunately, the G12C mutation of KRAS in pancreatic cancer is rare, therefore pancreatic cancer patients could not benefit from the recent revolution of KRAS target therapies.

    Title translation Molecular basis of hereditary cancers.
    Abstract Cancer susceptibility but not specific cancer types can be inherited. This susceptibility(ies) is due to inherited germline mutations of key genes of the controllers of genome integrity, translational control, the cell cycle regulation or even the tumor vascularization. Cancer susceptibility can be manifested in various forms of specific syndromes, each associated with different alterations of genes. Most of these genes are tumor suppressors, and the mutations affect one or both alleles. Interestingly, inherited mutations of oncogenes resulting in cancer susceptibility are much rarer, typically affect only one allele, and the inheritance is dominant. However, cancer susceptibility is influenced not only by high penetrance gene defects but also by inherited low penetrance gene mutations, complicating the effective identification of affected individuals and their families.

    Title translation Molecular pathology of prostate cancer.
    Abstract Prostate cancer seems to be two diseases: a localized early cancer and a castration-resistant metastatic cancer. While in the localized form the most prevalent genetic alterations are the translocations of the ETS genes, in the castration-resistant form the most prevalent genetic alteration affects androgen receptor and oncosuppressors TP53 and PTEN. The main drivers of the genetic progression of prostate cancer are defects of the DNA-repair systems which are also responsible for the familiar disease. Several prognostic genomic classifiers have been developed and validated clinically which are able to guide management of the early diseases. Today the most useful predictive genetic testing is that of the androgen receptor but others are becoming equally important which can predict taxane resistance.

    Title translation Pathological diagnostics of CUP (Cancer of Unknown Primary).
    Abstract CUP (Cancer of Unknown Primary) is a relatively frequent cancer type causing incomparable difficulties in pathological diagnosis as compared to other tumor types. The primary may even remain unknown at authopsy due to microscopic size or previous regression. By applying the biological, epidemiological cancer information it is possible to compose rational pathological differential diagnostic algorithms to define with high probability the primary site of the cancer. The new molecular tests developed for CUP are very helpful especially if they are used in combination with pathological data.

    Abstract Triadic closure, the formation of a connection between two nodes in a network sharing a common neighbor, is considered a fundamental mechanism determining the clustered nature of many real-world topologies. In this work we define a static triadic closure (STC) model for clustered networks, whereby starting from an arbitrary fixed backbone network, each triad is closed independently with a given probability. Assuming a locally treelike backbone we derive exact expressions for the expected number of various small, loopy motifs (triangles, 4-loops, diamonds, and 4-cliques) as a function of moments of the backbone degree distribution. In this way we determine how transitivity and its suitably defined generalizations for higher-order motifs depend on the heterogeneity of the original network, revealing the existence of transitions due to the interplay between topologically inequivalent triads in the network. Furthermore, under reasonable assumptions for the moments of the backbone network, we establish approximate relationships between motif densities, which we test in a large dataset of real-world networks. We find a good agreement, indicating that STC is a realistic mechanism for the generation of clustered networks, while remaining simple enough to be amenable to analytical treatment.
