Background: A majority of patients with lung cancer are incurable but are symptomatic and may benefit from palliative therapy. Currently available diagnostic methods are either too risky or unsuccessful in obtaining a tissue diagnosis in up to 30% of patients.
Objective: To evaluate the role of EUS-guided FNA in obtaining a tissue diagnosis in patients with advanced lung cancer.
Design: Prospective, uncontrolled.
Setting: Veterans Administration Medical Center.
Subjects And Methods: Patients with suspected lung cancer who were not candidates for curative therapy were prospectively identified. CT scans were reviewed, and patients with lesions considered suitable for sampling by EUS were enrolled. Outcomes were analyzed by a final tissue diagnosis or by serial imaging.
Results: Sixty-nine patients met inclusion criteria, of which 3 refused participation. The remaining 66 patients constituted the study population. EUS was technically successful in 95% of patients. A final diagnosis was based on tissue in 63 of 66 patients, serial imaging in 1 of 66 patients, and was unavailable in 2 of 66 patients. A lung mass was sampled in 21 patients, and a metastatic lesion was sampled in 45 patients. EUS made a correct diagnosis in 55 of 64 patients (86%, 95% confidence interval [CI] 77%-93%), including 24% that had undergone a failed prior attempt at diagnosis. The sensitivity of EUS was 86%, and the specificity was 100%. Sampling a metastasis was more likely to yield a correct diagnosis than sampling a lung mass (P = .02). Two self-limited complications were noted during the study.
Conclusions: EUS was an accurate and a safe method for obtaining a tissue diagnosis in patients with advanced incurable lung cancer.

Background: Immuno-chemotherapy has demonstrated significant anti-tumor effects in patients with resectable nonsmall cell lung cancer (NSCLC). Additionally, for patients initially diagnosed with unresectable stage III NSCLC, induction immuno-chemotherapy may achieve tumor downstaging, enabling conversion to resectable disease allowing for by R0 resection. This study aimed to assess the effectiveness and safety of induction immuno-chemotherapy followed by conversion surgery in unresectable stage III NSCLC.

Background: Small cell lung cancer (SCLC) is initially highly sensitive to chemotherapy, which often leads to significant tumor reduction. However, the majority of patients eventually develop resistance, and the disease is further complicated by its "cold" tumor microenvironment, characterized by low tumor immunogenicity and limited CD8+ T cell infiltration. These factors contribute to the poor response to immunotherapy in many cases of extensive-stage SCLC (ES-SCLC).

Malignant peripheral nerve sheath tumours (MPNSTs) are aggressive sarcomas that occur rarely in the cervix. Considering the varied clinical features and the absence of a pathognomonic immunohistochemical marker, it is always challenging to diagnose these tumours. Treatment has not been standardised as yet, but a combination of surgery, radiotherapy and chemotherapy is used to treat MPNSTs of the cervix.

Background: More efficient therapeutic options for non-small cell lung cancer (NSCLC) are needed as the survival at 5 years of metastatic disease is near zero. In this regard, we used a preclinical model of metastatic lung adenocarcinoma (SV2-OVA) to assess the safety and efficacy of novel radio-immunotherapy combining hypofractionated radiotherapy (HRT) with muPD1-IL2v immunocytokine and muFAP-CD40 bispecific antibody.
Methods: We evaluated the changes in the lung immune microenvironment at multiple timepoints following combination therapies and investigated their underlying antitumor mechanisms.
