12028 Background: Performance status (e.g. Eastern Cooperative Oncology Group [ECOG] score) is a predictive tool used to determine whether a patient may benefit from cytotoxic chemotherapy. The toxicity profile of immunotherapy is different, and less is known about whether performance status (PS) is similarly associated with toxicity and benefit. Nonetheless, most clinical trials for immune checkpoint inhibitors have excluded patients with poor PS. Emerging data by our group and others has linked poor PS with lack of response and decreased survival with anti-PD-1/L1 agents, but whether combination therapy abrogates the poor outcomes of PD1 only therapy is unknown. Methods: We conducted a retrospective cohort study of patients with metastatic cancer who received ipilimumab plus nivolumab at our institution between January 2014-December 2020. We compared outcomes between those with good PS (Group A, ECOG PS 0-1) and poor PS (Group B, ECOG PS ≥ 2). Our primary outcomes were overall survival (OS) and incidence of grade 3-4 immune-related adverse events (irAEs). Other outcomes included objective response rates and need for hospitalization. We utilized the Kaplan-Meyer method for time to survival analysis and exact Pearson Chi-squared testing for response, toxicity, and hospitalization analysis. Results: A total of 129 patients were identified with a mean age of 59.9 years. Among them were 73 males (57%) and 56 females (43%). Malignant melanoma was the most common malignancy (39%) followed by renal cell carcinoma (27%), small cell lung cancers (10%), non-small cell lung cancers (9%), and the rest with other histologies. 113 patients (87.6%) were in group A and 16 (12.4%) in group B. Across all tumor types, patients in Group B had significantly worse OS compared to group A (HR 0.24 [0.13-0.48], P = < 0.0001). Group B similarly had higher rates of hospitalization compared to group A (94% vs 56%, P = 0.0048). Interestingly, irAEs were not driving these hospitalizations, with a trend toward lower rates of irAEs in the poor PS group (19% vs 46% in Group A, P = 0.057). The overall response rate in group B was numerically lower (6% vs 26% in group A, p = 0.1). Conclusions: Our study showed that using ipilimumab plus nivolumab in patients with poor PS was associated with significantly poorer OS and higher rates of hospitalizations. irAEs were not increased in the poor PS group, suggesting a lack of treatment efficacy seemed to driving these poor outcomes. Extrapolation of clinical trial data for ipilimumab-nivolumab to a broader population including those with poor PS should be done with caution. Unfortunately, our data showed that most patients with poor PS were not adequately palliated with ipilimumab-nivolumab.

PURPOSE The transmembrane-4 superfamily (TM4SF) is a recently discovered family of genes. Of the TM4SF members, MRP-1/CD9, KAI1/CD82, and ME491/CD63 have been reported to modulate tumor progression or metastasis. In this study, we investigated the relationships between these three genes, MRP-1, KAI1, and ME491, in patients with non-small-cell lung cancers (NSCLCs). Moreover, we assessed the prognostic value of evaluating the expressions of MRP-1, KAI1, and ME491 simultaneously in NSCLCs. PATIENTS AND METHODS One hundred seventy-two patients up to stage IIIB NSCLC underwent radical surgery during the period of January 1991 through June 1994. Using a quantitative reverse-transcriptase polymerase chain reaction (RT-PCR) analysis, we studied the expression of MRP-1, KAI1, and ME491 genes in these patients. RESULTS We found that 109 patients (63.4%) had MRP-1-positive tumors and 42 patients (24.4%) had KAl1-positive tumors. Conversely, all 172 patients expressed ME491. No relationship was found between MRP-1 expression and KAI1 expression. We classified these patients into three groups. The 36 patients who were positive for both MRP-1 and KAI1 were defined as group A; the 79 patients with reduced expression of either MRP-1 or KAI1 were defined as group B, and the remaining 57 patients with reduced expression of both MRP-1 and KAI1 were defined as group C. This new classification was correlated with nodal status, tumor status, and pathologic stage (P = .0056, P = .0003, and P < .0001, respectively). In NSCLC patients, the 5-year survival rate of group A patients was significantly better than that of group B patients and much better than that of group C patients (86.8%, 53.9%, and 31.5%, respectively; P < .0001). Cox multivariate regression analysis showed that this new classification in NSCLCs was a significant prognostic factor, as was the nodal status (P < .0001). CONCLUSION Our results suggest that a low MRP-1 and KAI1 expression by tumors of the lung may be associated with poor prognosis. It is conceivable that the evaluation for MRP-1 and KAI1 expression may identify node-negative lung cancer patients who are at high risk for early disease recurrence, and thus need intensive adjuvant therapy.

BackgroundPatients with non–small cell lung cancer (NSCLC) and a poor Eastern Cooperative Oncology Group Performance Status (ECOG PS) have been excluded from phase III immunotherapy clinical trials. We sought to evaluate clinical outcomes to first-line pembrolizumab in patients with advanced NSCLC, a PD-L1 Tumor Proportion Score (TPS) of ≥50%, and an ECOG PS of 2.MethodsWe performed a multicenter retrospective analysis of patients with metastatic NSCLC and a PD-L1 TPS of ≥50% (negative for genomic alterations in EGFR and ALK) who received treatment with first-line pembrolizumab. Clinical outcomes were compared in patients based on ECOG PS.ResultsAmong the 234 patients, 83.3% (n=195) had an ECOG PS of 0 or 1, and 16.7% (n=39) had an ECOG PS of 2. The baseline clinicopathological characteristics were balanced between the ECOG PS 0–1 vs 2 groups in terms of age, sex, tobacco use, histology, KRAS mutation status, presence of other potentially targetable driver mutations (BRAF, MET, HER2, RET), presence of brain metastases, and PD-L1 TPS distribution. Compared with patients with an ECOG PS of 0 or 1, patients with an ECOG PS of 2 had a significantly lower objective response rate (43.1% vs 25.6%; p=0.04), a numerically shorter median progression-free survival (6.6 months vs 4.0 months; HR 0.70 (95% CI 0.47 to 1.06); p=0.09), and a significantly shorter median overall survival (20.3 months vs 7.4 months; HR 0.42 (95% CI 0.26 to 0.68); p<0.001). On disease progression, patients with an ECOG PS of 2 were significantly less likely to receive second-line systemic therapy compared with patients with an ECOG PS of 0–1 (65% vs 22.2%, p=0.001).ConclusionsA subset of patients with NSCLC and an ECOG PS of 2 can respond to first-line pembrolizumab. However, clinical outcomes in this population are often poor and use of second-line systemic therapy is infrequent.

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.

e18546 Background: Small cell lung cancers (SCLC) constitute a mean of 15% of lung cancers and present with advanced disease at time of diagnosis in 60% of cases. Cisplatin plus etoposide schedule is the standard treatment in these patients , whereas the role of maintenance therapy is debated. We assessed the efficacy and safety of oral etoposide maintenance therapy following cisplatin plus etoposide in advanced SCLC. Methods: Demographic features, treatment response, survival rate, and toxicity rate were assessed in our patients who were followed up for advanced SCLC between 2006 and 2012, had a ECOG performance status of 0-1, and were given oral etoposide maintenance therapy (50mg/day, given 14 days of a 21-day cycle, a total of 6 cycles) following 6 courses of cisplatin (75 mg/m2, 1 day) and etoposide (100mg/m2, 3 days). Results: A total of 51 patients were studied, 46 (90.2%) of whom were male; the mean age was 59 (28-78) years at diagnosis. Forty-four (86.2%) patients had partial remission while 7 (13.7%) had complete remission. Nine (17.6%) developed neutropenic fever while grade 3-4 toxicities, neutropenia, anemia, thrombocytopenia, neuropathy, diarrhea, nausea and vomiting were present in 39.2%, 9.8%, 5.9%, 1.9%, 3.9%, 3.9%, and 1.9% respectively. Chemotherapy was postponed in fourteen (27.4%) patients due to toxicity. Six (11.7%) patients taking oral etoposide developed febrile neutropenia and 3 (5.9%) developed grade 3-4 thrombocytopenia. Chemotherapy was postponed in 5 (9.8%) patients due to toxicity while no toxic death was observed. After a median follow-up of 19 months, 32 (62.7%) patients experienced progression of disease and 29 (56.8%) died. Median progression free survival was found 11.6 months (%95 CI; 10.2-12.9 months) and median overall survival was found 15.6 (%95CI; 11.5-19.7 months) months. Conclusions: Our results were similar with the previous literature. Oral etoposide maintenance therapy following cisplatin plus etoposide therapy in advanced SCLC is effective and tolerable. Further randomized studies are needed in this topic.

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]

AbstractObjectiveWearable devices such as a wrist actigraph may have a potential to objectively estimate patients’ functioning and may supplement performance status (PS). This proof-of-concept study aimed to evaluate whether actigraphy data are significantly associated with patients’ functioning and are predictive of their survival in patients with metastatic non-small cell lung cancer.MethodWe collected actigraphy data for a three-day period in ambulatory patients with stage IV non-small cell lung cancer. We computed correlations between actigraphy data (specifically, proportion of time spent immobile while awake) and clinician-rated PS, subjective report of physical activities, quality of life (the Functional Assessment of Cancer Therapy – Trial Outcome Index), and survival.ResultActigraphy data (the proportion of time awake spent immobile) were significantly correlated with Functional Assessment of Cancer Therapy – Trial Outcome Index (r = −0.53, p < 0.001) and with the Eastern Cooperative Oncology Group PS (ECOG PS) (r = 0.37, p < 0.001). The proportion of time awake spent immobile was significantly associated with worse survival. For each 10% increase in this measure, the hazard ratio (HR) was 1.48 (95% confidence interval [CI95%] = 1.06, 2.06) for overall mortality, and odds ratio was 2.99 (CI95% = 1.27, 7.05) for six-month mortality. ECOG PS was also associated with worse survival (HR = 2.80, CI95% = 1.34, 5.86). Among patients with ECOG PS 0-1, the percentage of time awake spent immobile was significantly associated with worse survival, HR = 1.93 (CI95% = 1.10, 3.42), whereas ECOG PS did not predict survival.Significance of ResultsActigraphy may have potential to predict important clinical outcomes, such as quality of life and survival, and may serve to supplement PS. Further validation study is warranted.

We sought to evaluate clinical outcomes to first-line pembrolizumab in patients with advanced NSCLC, a PD-L1 tumor proportion score (TPS) of ≥50%, and an ECOG PS of 2. Methods: We performed a multicenter retrospective analysis of patients with metastatic NSCLC and a PD-L1 tumor proportion score (TPS) of ≥50% (negative for genomic alterations in EGFR and ALK) who received treatment with first-line commercial pembrolizumab. Clinical outcomes were compared in patients based on ECOG PS. Results: Among 234 patients, 83.3% (N = 195) had an ECOG PS of 0 or 1, and 16.7% (N = 39) had an ECOG PS of 2. The baseline clinicopathological characteristics were balanced between the ECOG PS 0-1 vs 2 groups in terms of age, sex, tobacco use, histology, KRAS mutation status, presence of other potentially targetable driver mutations ( BRAF, MET, HER2, RET), history of central nervous system (CNS) disease, and PD-L1 TPS distribution. Compared to patients with an ECOG PS of 0-1, patients with an ECOG PS of 2 had a significantly lower objective response rate (ORR 43.1% vs 25.6%; P = 0.04), a numerically shorter median progression free survival (mPFS 6.6 months vs 4.0 months; P = 0.09), and a significantly shorter median overall survival (mOS 20.3 months vs 7.4 months; P < 0.001). Upon disease progression, patients with an ECOG PS of 2 were significantly less likely to receive second-line systemic therapy compared to patients with an ECOG PS of 0-1 (55.5% vs 14.3%, P < 0.001). Conclusions: Although a subset of patients with an ECOG PS of 2 can respond first-line pembrolizumab, clinical outcomes in this population are poor, and use of second-line systemic therapy is infrequent.

e21538 Background: Advanced non-small cell lung cancer (NSCLC) patients with tumors harboring STK11/LKB1 or KEAP1 mutations have inferior treatment outcomes when treated with PD-1/PD-L1 blockade, regardless of KRAS status, PD-L1 score, or TMB score (Skoulidis et al, Cancer Discovery 2018, ASCO abstract 102, 2019). Methods: Retrospective clinical databases from Indiana University and Karmanos Cancer Institute were queried to identify patients from 2008-2019 with advanced NSCLC treated with PD-1/PD-L1 monotherapy (group A) or concurrent chemotherapy + PD-1/PD-L1 inhibitors (group B) whose tumors harbored STK11/LKB1 and/or KEAP1 mutations. Patients were characterized by best response, progression of disease (PD) or non-PD (complete response (CR) + partial response (PR) + stable disease (SD)). Patient and disease characteristics, response, and duration of response (> vs. < 6 months) were recorded. Results: A total of 77 patients met the above criteria (55 in group A, 22 in group B). 52 of 55 patients in group A received prior chemo. Patient and disease characteristics and outcomes are summarized in the table. Conclusions: STK11/LKB1 and/or KEAP1 mutations are independent of PD-L1/TMB status, although most patients had PD-L1 of <1%. Nearly ½ of patients with STK11/LKB1 and/or KEAP1 mutations achieve at least SD with PD-1/PD-L1 inhibitor monotherapy and more than 50% of those with non-PD maintain that response status for > 6 mos. The frequency and duration of non-PD in this population is higher in patients receiving chemotherapy + PD-1/PD-L1 concomitantly. [Table: see text]

Pemetrexed (used as a platinum doublet or as a maintenance regimen) is an established therapy for patients with advanced non-squamous non-small-cell lung cancer (NSCLC). In addition, certain gene rearrangements (e.g., ALK, ROS1, RET) appear to especially benefit from the use of pemetrexed. Inferior outcomes with pemetrexed compared to other chemotherapies in patients with NSCLC demonstrating squamous histology removed these patients from the labeled indication for the drug. While most squamous cases do not harbor driver oncogenes, rare exceptions exist. Whether the poor outcomes with pemetrexed extend to NSCLC with squamous component harboring driver oncogenes remains unexplored. In this case series, we describe two patients with adenosquamous histology harboring an ROS1 and ALK gene arrangement, respectively, who derived significant benefit from pemetrexed-based therapy. These cases suggest that the value of pemetrexed may need to be re-explored in adenosquamous NSCLC harboring such alterations.
