Background: Studies have shown that aggressive treatment of non-small cell lung cancer (NSCLC) with oligometastatic disease improves the overall survival (OS) compared to a palliative approach and some immunotherapy checkpoint inhibitors, such as anti-programmed cell death ligand 1 (PD-L1), anti-programmed cell death protein 1 (PD-1), and T-Lymphocyte-associated antigen 4 (CTLA-4) inhibitors are now part of the standard of care for advanced NSCLC. However, the prognostic impact of PD-L1 expression in the oligometastatic setting remains unknown. Methods: Patients with oligometastatic NSCLC were identified from the patient database of the Centre hospitalier de l’Université de Montréal (CHUM). “Oligometastatic disease” definition chosen is one synchronous metastasis based on the M1b staging of the eight IASLC (The International Association for the Study of Lung Cancer) Classification (within sixth months of diagnosis) or up to three cerebral metastasis based on the methodology of the previous major phase II randomized study of Gomez et al. We compared the OS between patients receiving aggressive treatment at both metastatic and primary sites (Group A) and patients receiving non-aggressive treatment (Group B). Subgroup analysis was performed using tumor PD-L1 expression. Results: Among 643 metastatic NSCLC patients, we identified 67 patients with oligometastasis (10%). Median follow-up was 13.3 months. Twenty-nine patients (43%) received radical treatment at metastatic and primary sites (Group A), and 38 patients (57%) received non-aggressive treatment (Group B). The median OS (mOS) of Group A was significantly longer than for Group B (26 months vs. 5 months, p = 0.0001). Median progression-free survival (mPFS) of Group A was superior than Group B (17.5 months vs. 3.4 months, p = 0.0001). This difference was still significant when controlled for primary tumor staging: stage I (p = 0.316), stage II (p = 0.024), and stage III (p = 0.001). In the cohort of patients who were not treated with PD-L1 inhibitors, PD-L1 expression negatively correlated with mOS. Conclusions: Aggressive treatments of oligometastatic NSCLC significantly improve mOS and mPFS compared to a more palliative approach. PD-L1 expression is a negative prognostic factor which suggests a possible role for immunotherapy in this setting.

Objective: The objective of this research is to explore the diagnostic value of imaging plus tumor markers in the early detection of lung cancer.Methods: Sixty patients with lung cancer treated in our hospital from January 2018 to January 2019 were selected as group A. They were matched with 60 patients with benign lung disease as group B and 60 healthy subjects examined in our hospital as group C. The carcino-embryonic antigen (CEA), CYFRA21-1, and neuron-specific enolase (NSE) were assessed, and the diagnostic value of tumor markers plus imaging in lung cancer diagnosis was explored.Results: The CEA, CYFRA21-1, and NSE in group A were evidently superior to those in groups B and C, and those in group B were superior to those in group C (all P < 0.001). CEA had the highest sensitivity (56.7%), and NSE had the highest specificity (93.3%). The tumor markers plus imaging had the highest sensitivity for different types of lung cancer, and the sensitivity to early lung cancer (90%) was superior to other diagnostic methods (P < 0.05).Conclusion: The tumor markers plus imaging is of great significance in early lung cancer diagnosis and provides a reference for judging the pathological classification.

Abstract Total lactate dehydrogenase (LD, EC 1.1.1.27) activity in serum and LD isoenzymes were quantified at the time of diagnosis in 320 patients with bacterial pneumonia. In eighty, LD activity was increased, but this was accompanied by either other pathological results for liver-function tests or associated diseases that could explain it. The remaining 240 patients were divided into four groups, based on their total serum LD values: group A, less than 225 U/L (normal limit); group B, 226-350 U/L; group C, 351-499 U/L; and group D, greater than 500 U/L. Total LD was above normal at diagnosis in 40% of the patients. Recovery time was twice as long in group D as in groups A, B, and C. In five patients from group D, the pneumonia reflected underlying lung cancer. In groups B and C, the LD-3 ratio was increased in comparison with group A; in group D, LD-4 and LD-5 were increased up to twice the normal limit. Evidently nearly half of patients with bacterial pneumonia may show isolated increases in total LD activity (mostly LD-3) in serum. In cases with high activity, prolonged recovery time is expected. Intensive follow-up and extensive investigation are warranted in these patients, because some may have underlying lung cancer.

1. The susceptibility of mice to the lethal effect of preparations containing the oxygen-labile hemolysin (streptolysin O) of group A hemolytic streptococci has been studied. Injection of a single sublethal dose of the streptococcal preparation causes the development of resistance to the effect of a lethal dose injected subsequently. 2. Resistance is demonstrable 3 to 6 hours after the injection of the streptococcal preparation, persists for approximately 30 hours, and then disappears. 3. Resistance induced by the streptococcal preparation, although relatively specific, is directed not only against the streptococcal preparation but also against saponin. Mice made refractory to the streptococcal preparation and to saponin exhibit normal susceptibility to a number of other toxic agents, with the possible exception of the alpha toxin of Cl. welchii. 4. Mice injected with a sublethal dose of saponin develop resistance to the effect of a lethal dose of either saponin or the streptococcal preparation. 5. Resistance depends upon processes distinct from those underlying classical antitoxic immunity.

Abstract Background For patients with stage IA non-small cell lung cancer (NSCLC) with tumor size ≤ 2 cm, the prognostic significance of the number of removed lymph nodes (NLNs) through different surgical methods remains unclear. To determine the association of NLNs with cancer-specific survival (CSS) and overall survival (OS) in patients with stage IA NSCLC with tumor size ≤ 2 cm who underwent different lung surgeries. Methods We retrospectively enrolled 7293 patients from the Surveillance, Epidemiology and End Results database. Median NLNs was used to classify the patients into two groups: group A with NLNs ≤ 5 and group B with NLNs > 5. Propensity score matching (PSM) was performed to decrease selection bias. Kaplan–Meier analysis and Cox regression analysis were performed to identify the association between NLNs and survival outcomes. Results Group B had better survival than group A in the unmatched cohort and matched cohort (all P < 0.05). Multivariable analyses revealed that the NLNs significantly affected CSS and OS of eligible cases in the unmatched cohort and matched cohort. Additionally, we found that the NLNs was a protective prognostic predictor of OS for patients who underwent wedge resection, segmental resection, or lobectomy. Conclusion The NLNs was a protective prognostic factor in NSCLC patients with tumor size ≤ 2 cm. We demonstrated that patients with > 5 NLNs in the cohort of wedge resection, segmental resection, or lobectomy exhibited a significantly better OS.

Abstract Background Non–small-cell lung cancer (NSCLC) has been reported to develop in patients with interstitial pneumonia (IP); however, clinical, radiological, and pathological features remain to be elucidated. Methods We retrieved the records of 120 consecutive NSCLC patients associated with IP who underwent surgery at Toranomon Hospital between June 2011 and May 2017. We classified the patients into three groups according to NSCLC location using high-resolution computed tomography: group A, within a fibrotic shadow and/or at the interface of a fibrotic shadow and normal lung; group B, within emphysematous tissue and/or at the interface of emphysematous tissue and normal lung; and group C, within normal lung. In 64 patients, programmed death ligand-1 (PD-L1) status was assessed with immunohistostaining. Results Most of the patients (89; 70%) were classified as group A. This group tended to have squamous cell carcinoma with the usual interstitial pneumonia (UIP). These cancers were located mainly in the lower lobes and seven of the eight postoperative acute exacerbations (pAE) of IP developed in this group. NSCLC in the group B were mainly squamous cell carcinomas located in the upper lobes. No patient with PD-L1 negative was classified into group B. None of the patients in group C showed UIP. and most of the cancers were adenocarcinoma. The frequency of epidermal growth factor receptor mutation-positive NSCLC was the highest in this group. Conclusions The three groups each showed characteristic features in terms of tumor location, histopathology, PD-L1 expression, and frequency of pAEof IP.

e20601 Background: Central nervous system (CNS) metastases (mets) occur in 30% of patients with advanced non-small cell lung cancer (NSCLC) and are associated with poor overall survival (OS). Although nivolumab, a programmed death-1 immune checkpoint inhibitor antibody, has demonstrated a longer survival benefit compared with docetaxel in previously treated NSCLC patients (CheckMate 017 and 057; N Engl J Med, 2015), patients with symptomatic or untreated CNS mets were excluded in these trials. In CheckMate 012 Arm M, 2 of 12 patients (16.7%) with untreated CNS mets showed intracranial responses, but the effect of nivolumab treatment for CNS mets was not fully investigated. Methods: To investigate the effect and safety of nivolumab for CNS mets in NSCLC patients, we retrospectively analyzed 48 patients with NSCLC who were treated with nivolumab from February 2016 to December 2016 at Okayama University Hospital. Results: Twenty-nine patients (60%) had no CNS lesions (group A) and 19 patients (40%) had brain mets (BM) (group B). In group B, 15 patients (79%) received radiotherapy (RT) for BM, including 5 patients who received RT just before nivolumab treatment. The responses of extra-CNS lesions to nivolumab are shown in the table. The PFS was longer in group A than in group B (p=0.14). In group B, the PFS of patients who received prior RT tended to be longer than in those without RT (p=0.42); OS was not reached in either group. In group B, the effects of nivolumab treatment for CNS mets were evaluated in 12 patients: SD occurred in 3 patients (25%), PD in 4 patients (33%), and NE in 5 patients (42%). All 4 patients with PD in the CNS lesion also showed PD in the extra-CNS lesion. In group A, no patients showed progression only in the CNS lesion. Conclusions: In this retrospective study, there were no patients treated only with nivolumab who showed a response to CNS mets. RT prior to nivolumab might be more effective, so future investigations should involve additional cases and prospective studies. [Table: see text]
