Methods The data of patients with lung metastases from colon cancer who underwent SABR were retrospectively evaluated according to the following inclusion criteria: number of metastases ≤3; lung oligometastases from colon cancer in patients who underwent SABR; patients receiving previous chemotherapy alone or in combination with bevacizumab; Karnofsky performance status >80; life expectancy >6 months; at least 6 months' follow-up after SABR; presence of KRAS mutation.
We show that loss of HIF-1α or PLOD2 expression disrupts collagen modification, cell migration, and pulmonary metastasis (but not primary tumor growth) in allograft and autochthonous LSL-Kras(G12D/+); Trp53(fl/fl) murine sarcoma models.
In melanoma, V600K mutations in comparison to other BRAF mutations were associated with more frequent brain (75% vs. 36.3%, p = 0.02) and lung metastases (91.6% vs. 47.7%, p = 0.007), and shorter time from diagnosis to metastasis and to death (19 vs. 53 months, p = 0.046 and 78 vs. 322 months, p = 0.024 respectively).
Based on the mechanisms of CSCC carcinogenesis has been postulated that these tumors may be amenable to PD-1/PD-L1 blockade.This case illustrates a patient with CSCC with nodal involvement and pulmonary metastases, refractory to two lines of platinum-based regimens and salvage surgery, for whom treatment with nivolumab was recommended.
Left-sided tumors with wild-type KRAS had greater proportion of liver metastasis (78.6% versus 53.5%, P = 0.00), whereas those with mutant KRAS had greater proportion of lung metastasis (23.3% versus 8.7%, P = 0.02).
Multivariate analysis showed that primary tumor location (OR 3.92, p = 0.07) and KRAS mutation (OR 2.45, p = 0.09) were significant factors in lung metastasis model.
We retrospectively investigated the prognostic role of KRAS, BRAF, and PIK3CA (exon 20) mutations and loss of phosphatase and tensin homolog (PTEN) in surgically resected lung metastases.
We report a case of unusual computed tomography (CT) findings of pseudoprogression of pulmonary metastases in a patient with metastatic bladder cancer after durvalumab treatment: multiple pulmonary metastases turned into ground-glass opacity on first follow-up CT; on second follow-up CT, and after sustained treatment of the PD-L1 inhibitor, the lesion was resolved.
In particular, the luminal tumors are remarkable for their significant bone-seeking phenotype; the HER2 subtype demonstrates a significant liver-homing characteristic; whereas so-called triple-negative breast cancers predispose to lung metastases.
A distinct pattern of metastatic spread was observed in BRAF mutant tumors, namely higher rates of peritoneal metastases (46% vs 24%, P = .001), distant lymph node metastases (53% vs 38%, P = .008), and lower rates of lung metastases (35% vs 49%, P = .049).
The patient was a 66-year-old Chinese man, who had a history of metastatic lung cancer and was treated with first- and third-generation epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs).
Here we took advantage of the French National Cancer Institute Program of systematic molecular profiling of metastatic lung cancer, to collect clinical characteristics and analyze the outcome of consecutive patients with NSCLC harboring BRAF mutations at the Lyon University Hospital laboratory between February 2012 and October 2014.
Brain and lung metastases had higher KRAS mutations than other sites (65% vs 59% vs 47%, respectively, p = 0.07, <0.01), suggesting poor response to anti-EGFR therapies.
We focused on patients exhibiting 1 lung metastasis who underwent an AR (segmentectomy) or an NAR (wedge) and for whom the KRAS mutational status was known.
The correlation between EGFR mutation status and distant metastases showed statistical significance both in univariate (P = 0.022) and in multivariate analysis (OR 1.573, 95 % CI 1.202-2.059, P = 0.001) especially in brain metastases (OR 1.675, 95 % CI 1.132-2.479, P = 0.010) and lung metastases (OR 1.571, 59 % CI 1.101-2.243 P = 0.013).
These findings suggest that the BRAF(V600E) mutation can be detected using a PNA clamp real-time PCR in the blood of PTC patients with lung metastasis.
Drug administration of the combination of paclitaxel with the TNFα nanobody in vivo significantly enhanced the efficacy against 4T-1 breast tumor proliferation and lung metastasis; meanwhile, E-cadherin tumor epithelial marker expression was upregulated, supporting the anti-tumor therapeutic relevance of paclitaxel and the TNFα nanobody on EMT.
In this paper we studied the prognostic value of <sup>18</sup>F-FDG PET/CT scan uptake and also of iodine-131 (<sup>131</sup>I) in DTC patients with PM.
