KDR mutation

However, NACT patients with MYC-amplified tumors showed better disease-free survival (p = 0.04) compared to MYC-amplified patients without NACT. The overall survival of NACT group correlated with size >10 cm (p = 0.02), pathologic response (p = 0.04), and multifocality (p = 0.01) by univariate, while only size >10 cm (p = 0.03) remained significant by multivariate analysis.

ERBB4 and KDR mutations were observed in both with or without IP, and these genes may be tumor-related genes in SCC. These molecular markers may help determine the prognoses of patients with SCC with IP and direct the development of treatment approaches.

We conclude that VEGFA mediates zippering of VE-cadherin junctions in initial lymphatics. Zippering is accompanied by increased VE-cadherin fragmentation through VEGFA-induced Src kinase activation, correlating with tumor dissemination to sentinel lymph nodes.

Our study is the first to connect AA exposure to the etiology of liver AS. The high mutation rate and distinct telomere maintenance mechanism of liver AS provides insights into future treatments.

Our results highlight the presence of KDR mutations in primary CAS that have been reported predominantly in primary breast AS in previous studies. Primary CAS is characterized by POT1 mutations, which have previously been reported only in CAS in Li-Fraumeni like families. We are limited by the small number of samples with RNAseq data to derive inferences about the immune profile of CAS, which is also confounded by chemotherapy administered to the patients prior to surgical resection.

Ki-67 index is helpful to assess the degree and grade of tumor differentiation. The occurrence and development of PCAS may be related to the pathway involved in KDR mutation, but KDR mutation has no clear correlation with clinicopathological characteristics of PCAS, and immunohistochemical staining can not replace gene detection to determine whether the tumor had KDR mutation.

In summary, a significant proportion of HAS in Taiwan is associated with ESRD and harbors a distinctive mutational signature, which concomitantly links nephrotoxicity and mutagenesis resulting from the exposure to aristolochic acid or related compounds. High TMB may support the eligibility for immunotherapy in treating ESRD-associated HAS.

In ICI-treated bladder cancers, KDR mutation is associated with prolonged OS, higher TMB and activated antitumor immunity, which suggests that KDR mutation may serve as a potential biomarker to guide ICI therapy in bladder cancer.

Based on 2-tier system, the 5-year overall survival was 38% for high-grade angiosarcoma and 74% for low-grade angiosarcoma. PIK3CA mutations alone or concurrent with KDR alterations were identified in angiosarcomas with worse prognosis.

Additionally, in terms of safety, 55 patients experienced grade 2 or higher fatigue (incidence rate 40.74%) after receiving bevacizumab along with chemotherapy. The 889 C>T mutation in KDR gene affects the KDR expression in colorectal cancer patients, thereby affecting the effectiveness of bevacizumab therapy.

Meanwhile, KDR mutation was indicative of an immune-hot status, characterized by higher expression of PD-L1 and abundance of cytotoxic lymphocytes. KDR mutations may be potential positive predictors for pan-cancer received ICIs.

Maximal safe re-resection significantly lengthens PPS regardless of genetic makeup, but reoperations are especially beneficial for IDH-WT rGBMs with EGFR and CDKN2A/B mutations with TP53-WT, and NF1-WT. Histopathology at recurrence may be an imperfect gauge of disease severity at progression and the imaging progression may be more reflective of the prognosis.

Our work demonstrates that KDR mutation has the potential to become a predictive biomarker for ICIs.

Furthermore, activated VEGFR2 augments the dependence on glutamine (Gln) of melanoma cells, thus increasing Gln uptake and their sensitivity to Gln deprivation and to inhibitors of glutaminase, the enzyme initiating Gln metabolism by cells. Overall, these results highlight Gln addiction as a metabolic vulnerability of tumors harboring the activating VEGFR2 mutation and suggest novel therapeutic approaches for those patients harboring activating mutations of VEGFR2.
