Objective: To assess, using a large homogeneous retrospective series, the prognostic value of the number of resected pulmonary metastases, and thus, to determine to what extent the number of resectable metastases should influence the surgical decision.
Methods: The survival analysis of all patients operated on for pulmonary metastases at a single center, the comparisons of 2 'histologic' groups (sarcoma and carcinoma) and, within each histologic group, of three subgroups with different numbers of resected metastases (1, 2-4, and > or = 5) were performed. The log-rank test was used to compare survival curves.
Results: Among 575 adult patients operated on with curative intent before December 1991, the first operation allowed the complete resection of a known number of histologically proven viable pulmonary metastases in 230 and 151 patients with metastases from carcinoma and sarcoma, respectively. The 5- and 10-year probabilities of survival (Kaplan-Meier) were 37 and 23%, respectively in carcinoma patients, and 31 and 28%, respectively in sarcoma patients (log-rank test: ns). Only the difference between patients with 1 versus 2-4 metastases from carcinoma proved statistically significant (P = 0.02), with 5-year survival estimates of 41 and 25%, respectively. Beside survival, the only significant difference between the subgroups of patients with different numbers of resected metastases was the mean interval between the diagnosis of pulmonary metastases and the resection of pulmonary metastases, which was significantly longer in patients with several metastases in both histologic groups.
Conclusions: In patients with resectable pulmonary metastases from sarcoma or carcinoma, the number of metastases should have little influence on the surgical decision, except for delaying this decision in patients with several metastases until a significant interval, with or without treatment, has shown that metastatic disease remains resectable and confined to the lungs.

: ACEIs protect against radiation pneumonitis by reducing angiotensin II production, oxidative stress, and inflammation. This study highlights the significance of concurrent angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) use in radiotherapy by evaluating its impact on radiotherapy-related side effects and survival outcomes, addressing the gap in existing research and providing insights to guide clinical practice in oncology. : The literature was retrieved from the MEDLINE, EMBASE, Web of Science, and Scopus databases from January 2000 to October 2024.

Non-small-cell lung cancer (NSCLC) remains the leading cause of cancer-related deaths globally, with a persistently low five-year survival rate of only 14-17%. High rates of metastasis contribute significantly to the poor prognosis of NSCLC, in which inflammation plays an important role by enhancing tumor growth, angiogenesis, and metastasis. Targeting inflammatory pathways within cancer cells may thus represent a promising strategy for inhibiting NSCLC metastasis.

Metastatic cancer accounts for most cancer-related deaths, and identifying specific molecular targets that contribute to metastatic progression is crucial for the development of effective treatments. Hypoxia, a feature of solid tumors, plays a role in cancer progression by inducing resistance to therapy and accelerating metastasis. Here, we report that CCAAT/enhancer-binding protein beta (C/EBPβ) transcriptionally regulates () and thus promotes migration and invasion of non-small-cell lung cancer (NSCLC) cells under hypoxic conditions.

Prostate cancer (PCa) is a high-prevalence disease usually characterized by metastatic spread to the pelvic lymph nodes and bones and the development of visceral metastases only in the late stages of disease. Positron Emission Tomography (PET) plays a key role in the detection of PCa metastases. Several PET radiotracers are used in PCa patients according to the stage and pathological features of the disease, in particular Ga/F-prostate-specific membrane antigen (PSMA) ligands.

: Inadequate dosing and respiratory motion contribute to local recurrence for oligometastatic disease (OMD). While short-term LC rates are well-documented, data on long-term LC remain limited. This study investigated long-term LC after stereotactic body radiotherapy (SBRT), using respiratory motion management techniques.
