Authors: Wang S, Niu X, Bao X, Wang Q, Zhang J, Lu S, Wang Y, Xu L, Wang M, Zhang J Abstract Non‑small cell lung cancer (NSCLC) metastasis commonly occurs in bone, which often results in pathological fractures. Sustained phosphoinositide‑3‑kinase (PI3K) signalling promotes the growth of PI3K‑dependent NSCLC and elevates osteoclastogenic potential. The present study investigated the effects of a PI3K inhibitor on NSCLC growth in bone and osteoclast formation, and aimed to determine whether it could control symptoms associated with bone metastasis. A bone metastasis xenograft model was established by implanti...

Conclusions: SBRT is a safe and efficacious treatment for adrenal metastases, demonstrating local tumor control. Further study of the impact on survival and quality of life is warranted.

Abstract PURPOSE: To directly compare the utility for therapeutic outcome prediction of dynamic first-pass contrast-enhanced (CE)-perfusion area-detector computed tomography (ADCT), MR imaging assessed with the same mathematical method and 2-[fluorine-18]-fluoro-2-deoxy-d-glucose-positron emission tomography combined with CT (PET/CT) for non-small cell lung cancer (NSCLC) patients treated with chemoradiotherapy. MATERIALS AND METHODS: Forty-three consecutive stage IIIB NSCLC patients, consisting of 25 males (mean age ± standard deviation: 66.6 ± 8.7 years) and 18 females (66.4 ± 8.2 years...

ConclusionsSignificant associations emerged between PET features, CT features, and histological type in NSCLC. Texture analysis on PET/CT shows potential to differentiate between histological types in patients with non-small-cell lung cancer.

CONCLUSION: The present investigation demonstrates that the image-based manual determination of BSUV in the aorta is sufficiently reproducible across different observers and delineation tools which is a prerequisite for accurate SUR determination. This finding is in line with the already demonstrated superior prognostic value of SUR in comparison to SUV in the first clinical studies. PMID: 30830508 [PubMed]

Conclusion: All 4 response criteria were highly predictive of OS, but visual criteria showed greater interobserver agreement and stronger discrimination between CMR and non-CMR, highlighting the importance of visual assessment to recognize radiation pneumonitis, changes in lung configuration, and patterns of response.

Abstract PURPOSE: To evaluate the prognostic value of FDG PET/CT metabolic parameter compared to clinico-pathological risk factors in surgical margin-negative stage IA non-small cell lung cancer (NSCLC) patients. METHODS: 167 patients with consecutive FDG PET/CT scans from 2009 to 2015 performed for staging of NSCLC stage IA with plans for curative surgery were retrospectively reviewed. Maximum standardized uptake value (SUVmax) of primary tumor and mean SUV of liver were acquired from PET/CT. Tumor-to-liver SUV ratio (TLR) was calculated. Charts were reviewed to obtain basic patient characteristics (age, sex...

CONCLUSIONS: Coexistence of acromegaly and numerous other tumors suggests a common etiology of these disorders. However, no genetic abnormality could be identified with the tests that have been performed. PMID: 30742299 [PubMed - as supplied by publisher]
