PURPOSE: The clinical and research FPG500 program (ClinicalTrials.gov identifier: NCT06020625 ) is currently ongoing at the Fondazione Policlinico Universitario Agostino Gemelli IRCCS to tailor matched targeted therapies (MTTs) according to biomarkers predictive of response identified by comprehensive genome profiling (CGP). MATERIALS AND METHODS: The non–small cell lung cancer (NSCLC) cohort results from the FPG500 program are outlined. CGP was performed by TruSight Oncology 500 High Throughput (TSO500HT) assay or Oncomine Focus Assay plus Archer's FusionPlex Lung Panel according to tumor cell content and DNA/RNA quantity. Relevant issues for Molecular Tumor Board (MTB) evaluation included uncommon genomic findings, evaluation for off-label therapies, uncertain result confirmation, and variants of suspect germline origin requiring genetic counseling. Progression-free survival (PFS) and overall survival (OS) for the enrolled patients were assessed using Kaplan-Meier analysis. RESULTS: In 2022, 283 patients with NSCLC were considered for sequencing, with 93% meeting eligibility criteria. TSO500HT sequencing was conducted in 76% of patients. Follow-up data were obtained for 187 patients, among whom 81% received treatment. Potential driver alterations were identified in 59% of patients, with 41% receiving MTT: 25% were prescribed approved MTTs, whereas 16% gained access to experimental drugs post-MTB evaluation; of note, 18% did not receive any MTT because the regimen was not yet reimbursed in our country. Median PFS and OS varied among treatment groups, with standard chemotherapy/immunotherapy at 7.7 and 10.7 months, approved tyrosine kinase inhibitors at 18.8 and 23.9 months, and MTT post-MTB discussion at 14 and 23.4 months, respectively. CONCLUSION: The early data of the FPG program (NSCLC cohort) support the implementation of CGP and MTB in clinical practice to grant access to patients harboring actionable molecular alterations to the most effective and individualized available treatment options, thus improving their survival outcomes.
Background and Objective: Studies which evaluated the role of an ultrasound-guided needle aspiration biopsy (US-NAB) of metastases from lung cancer located in “superficial” organs/tissues are scant, and none of them assessed the possible impact of rapid on-site evaluation (ROSE) on diagnostic accuracy and safety outcomes. Methods: Consecutive patients with suspected superficial metastases from lung cancer were randomized 1:1 to US-NAB without (US-NAB group) or with ROSE (ROSE group). The diagnostic yield for a tissue diagnosis was the primary outcome. Secondary outcomes included the diagnostic yield for cancer genotyping, the diagnostic yield for PD-L1 testing, and safety. Results: During the study period, 136 patients were randomized to receive an US-NAB with (n = 68) or without ROSE (n = 68). We found no significant differences between the ROSE group and the US-NAB group in terms of the diagnostic yields for tissue diagnosis (94.1% vs. 97%, respectively; p = 0.68), cancer genotyping (88% vs. 91.8%, respectively; p = 0.56), and PD-L1 testing (93.5% vs. 90.6%, respectively; p = 0.60). Compared to the diagnostic US-NAB procedures, the non-diagnostic procedures were characterized by less common use of a cutting needle (66.6% vs. 96.9%, respectively; p = 0.0004) and less common retrieval of a tissue core (37.5% vs. 98.5%; p = 0.0001). Only one adverse event (vasovagal syncope) was recorded. Conclusion: US-NAB of superficial metastases is safe and has an excellent diagnostic success regardless of the availability of ROSE. These findings provide a strong rationale for using US-NAB as the first-step method for tissue acquisition whenever a suspected superficial metastatic lesion is identified in patients with suspected lung cancer.
Background and objective: Limited data exist regarding the adverse events of advanced diagnostic bronchoscopy, with most of the available information derived from retrospective datasets that primarily focus on early complications. Methods: We conducted a 15-month prospective cohort study among consecutive patients undergoing endosonography and/or guided bronchoscopy under general anesthesia. We evaluated the 30-day incidence of severe complications, any complication, unplanned hospital encounters, and deaths. Additionally, we analyzed the time of onset (immediate, within 1 h of the procedure; early, 1 h–24 h; late, 24 h–30 days) and identified risk factors associated with these events. Results: Thirty-day data were available for 697 out of 701 (99.4%) enrolled patients, with 85.6% having suspected malignancy and multiple comorbidities (median Charlson Comorbidity Index (IQR): 4 (2–5)). Severe complications occurred in only 17 (2.4%) patients, but among them, 10 (58.8%) had unplanned hospital encounters and 2 (11.7%) died within 30 days. A significant proportion of procedure-related severe complications (8/17, 47.1%); unplanned hospital encounters (8/11, 72.7%); and the two deaths occurred days or weeks after the procedure. Low-dose attenuation in the biopsy site on computed tomography was independently associated with any complication (OR: 1.87; 95% CI 1.13–3.09); unplanned hospital encounters (OR: 2.17; 95% CI 1.10–4.30); and mortality (OR: 4.19; 95% CI 1.74–10.11). Conclusions: Severe complications arising from endosonography and guided bronchoscopy, although uncommon, have significant clinical consequences. A substantial proportion of adverse events occur days after the procedure, potentially going unnoticed and exerting a negative clinical impact if a proactive surveillance program is not implemented.
The ability of high-definition (HD) videobronchoscopy to detect airway involvement in sarcoidosis has not been evaluated previously. What is the role of HD videobronchoscopy in the identification of sarcoidosis-associated airway abnormalities (AAs)? What are the patterns of AAs more commonly observed and more frequently associated with the detection of granulomas in endobronchial biopsy (EBB)? In this prospective international multicenter cohort study, consecutive patients with suspected sarcoidosis underwent airway inspection with an HD videobronchoscope and EBB using a standardized workflow. AAs were classified according to six patterns defined a priori: nodularity, cobblestoning, thickening, plaque, increased vascularity, and miscellaneous. We assessed diagnostic yield of EBB, prevalence of AAs, and interobserver agreement for different patterns of AAs. AAs were identified in 64 of 134 patients with sarcoidosis (47.8%), with nodularity (n = 23 [17.2%]), plaque (n = 19 [14.2%]), and increased vascularity (n = 19 [14.2%]) being the most prevalent. The diagnostic yield of EBB was 36.6%. AAs were significantly more prevalent in patients with than in those without nonnecrotizing granulomas on EBB (67.4% vs 36.5%; P = .001). Likewise, parenchymal disease on CT scan imaging was significantly more common in patients with than in those without nonnecrotizing granulomas on EBB (79.6% vs 54.1%; P = .003). On a per-lesion analysis, nonnecrotizing granulomas were seen especially in EBB samples obtained from areas of cobblestoning (9/10 [90%]) and nodularity (17/29 [58.6%]). The overall diagnostic yield of random EBB was low (31/134 [23.1%]). The interobserver agreement for the different patterns of AA was fair (Fleiss κ = 0.34). In a population with a large prevalence of White Europeans, HD videobronchoscopy detected AAs in approximately one-half of patients with sarcoidosis. The diagnostic yield of EBB was higher in patients with parenchymal involvement on CT scan imaging and in those with AAs, especially if manifesting as cobblestoning and nodularity.

New ultrathin bronchoscopes (UTBs) enable the inspection and biopsy of small airways, potentially offering diagnostic advantages in sarcoidosis. In this prospective study, patients with suspected sarcoidosis underwent airway inspection with a UTB. Observed airway abnormalities were categorised into six predefined patterns. UTB-directed small airway biopsies (SABs) were collected from the upper lobes following a standardised procedure. We evaluated the prevalence and patterns of SAAs, as well as the diagnostic yield of UTB-directed SAB. Among 79 participants, 65 (82.3%) were diagnosed with sarcoidosis. Small airway abnormalities were identified in 26/65 (40%) patients, predominantly in those with parenchymal involvement on CT compared to those with lymphadenopathy only (58.1% VS. 23.5%, P = 0.005). The diagnostic yield of SABs for detecting granulomas was significantly higher in patients with SAAs than in those without (65.4% VS. 23.1%, P = 0.001) and in patients with parenchymal disease on CT compared to those without (54.8% VS. 26.5%, P = 0.02). Notably, random biopsies taken under direct visualisation from small airway carinas revealed peribronchiolar parenchyma in 23% of the patients. Small airway abnormalities are prevalent in sarcoidosis patients with parenchymal involvement, and biopsying these abnormalities yields a high rate of granuloma detection.
