The present invention concerns prognostic markers associated with EGFR positive cancer. In particular, the invention concerns prognostic methods based on the molecular characterization of gene expression in paraffin-embedded, fixed tissue samples of EGFR-expressing cancer, which allow a physician to predict whether a patient is likely to respond well to treatment with an EGFR inhibitor.

In heart failure (HF) patients diagnosed according to the New York Heart Association (NYHA) rating scale as either Class III or Class IV, with QRS duration ≧120 ms, left ventricular (LV) EF≦35% (when in sinus rhythm), cardiac resynchronization therapy (CRT) can predict sustained improvement in at least LV structure and function. The knowledge of aetiology of a subject's HF status and of a few simple echocardiographic characteristics provides useful information as to whether such patients and undergo significant and beneficial reverse remodelling of the LV in particular and, in the long term can be expected to experience an improvement in all-cause mortality, for example such patients can be reasonably expected to survive and enjoy a relatively enhanced quality of life (QOL). A patient who qualifies according to the invention can be termed a reverse remodelling responder (RRR) or the like.

We examined IQGAP1 copy gain and its relationship with clinicopathologic outcomes of thyroid cancer and investigated its role in cell invasion and molecules involved in the process. We found IQGAP1 copy number (CN) gain ?3 in 1 of 30 (3%) of benign thyroid tumor, 24 of 74 (32%) follicular variant papillary thyroid cancer (FVPTC), 44 of 107 (41%) follicular thyroid cancer (FTC), 8 of 16 (50%) tall cell papillary thyroid cancer (PTC), and 27 of 41 (66%) anaplastic thyroid cancer, in increasing order of invasiveness of these tumors. A similar tumor distribution trend of CN ?4 was also seen. IQGAP1 copy gain was positively correlated with IQGAP1 protein expression. It was significantly associated with extrathyroidal and vascular invasion of FVPTC and FTC and, remarkably, a 50%-60% rate of multifocality and recurrence of BRAF mutation-positive PTC (P=0.01 and 0.02, respectively). The siRNA knock-down of IQGAP1 dramatically inhibited thyroid cancer cell invasion and colony formation. Co-immunoprecipitation assay showed direct interaction of IQGAP1 with E-cadherin, a known invasion-suppressing molecule, which was upregulated when IQGAP1 was knocked down. IQGAP1, through genetic copy gain, plays an important role in the invasiveness of thyroid cancer and represents a useful prognostic marker and therapeutic target for this and other cancers.

The method includes the following steps: (1) sample and clinical data collection; (2) sample preparation; (3) genomic DNA extration; (4) whole-genome CpG site methylation capture sequencing; and (5)methylation sequencing data analysis and marker screening. The method uses the whole-genome CpG site methylation capture sequencing technology to detect DNA methylation in acute myeloid leukemia and perform prognosis analysis, and screens genetic markers which are regulated by DNA methylation and has prognostic significance through information of integrative genetics and epigenetics to guide accurate diagnosis and treatment of AML, thereby improving the curative effect and improving the prognosis of patients.

The invention discloses a breast tumor prognosis biomarker LncRNA detection method and clinical application thereof, provides a group of new LncRNA in sequence shown as SEQ ID No1, SEQ ID No2, SEQ ID No3, SEQ ID No4 and SEQ ID No5 and relates to a method of taking specific LncRNA in samples (tissues, serum, urine, body fluid and the like) of patients suffering from breast tumors and corresponding juxtacancerous samples or normal samples as detection markers and biomarkers for prognostic auxiliary detection of breast tumors, related kits and a high-throughput sequencing and screening method. In-vitro diagnosis and judgment of canceration and process of breast tumors are realized by identification of differences of LncRNA expression quantity in the breast tumor samples and the corresponding juxtacancerous samples or normal samples. The invention further provides usage of the LncRNA as a breast tumor marker and probes and primers for LncRNA detection.

The invention provides an HNC (Head and Neck Cancer) prognosis biomarker based on a lymph node microbial flora and application of the HNC prognosis biomarker, and belongs to the technical field of disease prognosis and molecular biology. According to the invention, the 16S ribosomal RNA gene of the lymph node microbial flora of an HNC patient is subjected to high-throughput sequencing, so that it is proved that different species exist in flora species of metastatic lymph nodes and non-metastatic lymph nodes in the HNC patient; furthermore, through a microbial flora symbiotic relationship network, it is found that the flora interrelation between the species of the metastatic lymph node and the species of the non-metastatic lymph node of the HNC patient is also different at the genus level; the result discovers the characteristics of the microbiome of the metastatic lymph node and the non-metastatic lymph node of the HNC patient for the first time; and meanwhile, it is known by analysis that the flora difference characteristics (diversity index values and relative abundance of different species) have a good prediction effect on the lifetime (total lifetime and three-year lifetime) of the HNC patient, so that the invention has a good practical application value.

The invention relates to the use of a certain subset of cytokine markers as prognostic variables of infection status in an individual, and especially as prognostic markers of a patients developing severe infection such as pneumonia, and respiratory tract infection following surgery. The subset of cytokine markers consists of the interleukin cytokines IL-2, IL-7, IL-23, IL-27, and IL-10, and Interferon-γ (INFγ) and Tissue Necrosis Factor-α (TNFα). The markers may be employed as individual prognostic variables of infection status, or they may be used in pairs or other combinations. Generally, the abundance of the markers is correlated with infection status by means of an absolute pre-operative value of biomarker abundance, ratio's of pre-operative to post-operative biomarker abundance, or ratio values for pairs of certain biomarkers within the subset. Typically, cytokine abundance is expressed in terms of mRNA copy number wherein the copy numbers are ideally normalised to a house keeping gene and quantification of mRNA copy number is determined by RT-PCR containing reference serial dilutions of cytokine specific cDNA.
