Abstract
PURPOSE Cyclin D/CDK4/6 is critical in controlling the G1 to S checkpoint. CCND, the gene encoding cyclin D, is known to be amplified in a variety of solid tumors. Palbociclib is an oral CDK4/6 inhibitor, approved in advanced breast cancer in combination with endocrine therapy. We explored the efficacy of palbociclib in patients with nonbreast solid tumors containing an amplification in CCND1, 2, or 3. PATIENTS AND METHODS Patients with tumors containing a CCND1, 2, or 3 amplification and expression of the retinoblastoma protein were assigned to subprotocol Z1B and received palbociclib 125 mg once daily for 21 days of a 28-day cycle. Tumor response was assessed every two cycles. RESULTS Forty patients were assigned to subprotocol Z1B; 4 patients had outside assays identifying the CCND1, 2, or 3 amplification and were not confirmed centrally; 3 were ineligible and 2 were not treated (1 untreated patient was also ineligible), leaving 32 evaluable patients for this analysis. There were no partial responses; 12 patients (37.5%) had stable disease as best response. There were seven deaths on study, all during cycle 1 and attributable to disease progression. Median progression-free survival was 1.8 months. The most common toxicities were leukopenia (n = 21, 55%) and neutropenia (n = 19, 50%); neutropenia was the most common grade 3/4 event (n = 12, 32%). CONCLUSIONS Palbociclib was not effective at treating nonbreast solid tumors with a CCND1, 2, or 3 amplification in this cohort. These data do not support further investigation of single-agent palbociclib in tumors with CCND1, 2, or 3 amplification.

Abstract
PURPOSE NCI-MATCH is a precision medicine trial using genomic testing to allocate patients with advanced malignancies to targeted treatment subprotocols. This report combines two subprotocols evaluating trametinib, a MEK1/2 inhibitor, in patients with Neurofibromatosis 1 (NF1[S1] or GNA11/Q [S2]) altered tumors. METHODS Eligible patients had tumors with deleterious inactivating NF1 or GNA11/Q mutations by the customized Oncomine AmpliSeq panel. Prior MEK inhibitor treatment was excluded. Glioblastomas (GBMs) were permitted, including malignancies associated with germline NF1 mutations (S1 only). Trametinib was administered at 2 mg once daily over 28-day cycles until toxicity or disease progression. Primary end point was objective response rate (ORR). Secondary end points included progression-free survival (PFS) at 6 months, PFS, and overall survival. Exploratory analyses included co-occurring genomic alterations and PTEN loss. RESULTS Fifty patients were eligible and started therapy: 46 with NF1 mutations (S1) and four with GNA11 mutations (S2). In the NF1 cohort, nonsense single-nucleotide variants were identified in 29 and frameshift deletions in 17 tumors. All in S2 had nonuveal melanoma and GNA11 Q209L variant. Two partial responses (PR) were noted in S1, one patient each with advanced lung cancer and GBM for an ORR of 4.3% (90% CI, 0.8 to 13.1). One patient with melanoma in S2 had a PR (ORR, 25%; 90% CI, 1.3 to 75.1). Prolonged stable disease (SD) was also noted in five patients (four in S1 and one in S2) with additional rare histologies. Adverse events were as previously described with trametinib. Comutations in TP53 and PIK3CA were common. CONCLUSION Although these subprotocols did not meet the primary end point for ORR, significant responses or prolonged SD noted in some disease subtypes warrants further investigation.

Abstract
PURPOSE Bone marrow biopsies (BMB) are performed before/after therapy to confirm complete response (CR) in patients with lymphoma on clinical trials. We sought to establish whether BMB add value in assessing response or predict progression-free survival (PFS) or overall survival (OS) outcomes in follicular lymphoma (FL) subjects in a large, multicenter, multitrial cohort. METHODS Data were pooled from seven trials of 580 subjects with previously untreated FL through Alliance for Clinical Trials in Oncology (Alliance) and SWOG Cancer Research Network (SWOG) completing enrollment from 2008 to 2016. RESULTS Only 5/580 (0.9%) had positive baseline BMB, CR on imaging, and subsequent positive BMB (P < .0001). Therefore, BMB were irrelevant to response in 99% of subjects. A sensitivity analysis of 385 FL subjects treated on an Eastern Cooperative Oncology Group study was included. In the Eastern Cooperative Oncology Group cohort, 5/385 (1.3%) had BMB that affected response assessment. Since some subjects do not undergo confirmatory BMB, we performed a landmark survival analysis from first radiologic CR with data from 580 subjects from Alliance and SWOG. Of subjects with CR on imaging (n = 187), PFS and OS were not significantly different among those with negative BMB to confirm CR (n = 47) versus those without repeat BMB (n = 140; PFS: adjusted hazard ratio, 1.10, 95% CI, 0.62 to 1.94, log-rank P = .686; OS: hazard ratio, 0.59, 95% CI, 0.23 to 1.53, log-rank P = .276). CONCLUSION We conclude that BMB add little value to response assessment in subjects with FL treated on clinical trials and we recommend eliminating BMB from clinical trial requirements. BMB should also be removed from diagnostic guidelines for FL except in scenarios in which it may change management including confirmation of limited stage and assessment of cytopenias. This would reduce cost, patient discomfort, resource utilization, and potentially remove a barrier to trial enrollment.

Abstract
OBJECTIVE Greater perceived patient-centered communication (PCC) is associated with better health-related quality of life (HRQoL) in patients with ovarian cancer. Quantitative measures of PCC and HRQoL do little to explain this association. We interviewed patients with high and low ratings of PCC to understand how it is associated with HRQoL. METHODS Explanatory sequential mixed methods study. Participants were English-speaking U.S. adults with ovarian cancer. We assessed PCC with the Patient-Centered Communication - Cancer (PCC-Ca)-36 (possible score range 1-5; higher scores represent greater patient-centeredness), and purposively sampled 14 participants with total scores in the top and bottom quartiles. Participants completed individual, semi-structured interviews about their communication experiences. Guided by the National Cancer Institute Framework for PCC in Cancer Care, we analyzed interview transcripts using directed content analysis. We integrated survey and interview findings in a joint display. RESULTS Among 176 survey respondents, PCC-Ca-36 total scores ranged from 1.7 to 5.0. Participants with scores in the top quartile (4.8-5.0) perceived clinicians as proactive and attentive to psychosocial concerns. Those with scores in the bottom quartile (1.7-3.5) described not feeling known as an individual and receiving limited support for self-management. CONCLUSIONS The association between PCC and QoL may be partially explained by differences in perceived support for psychosocial concerns and self-management. PCC may facilitate receipt of proactive, personalized care.

Abstract
Background Although treatment decisions for localized prostate cancer (LPC) are preference-sensitive, the extent to which individuals with LPC receive preference-concordant treatment is unclear. In a sample of individuals with LPC, the purpose of this study was to (a) assess concordance between the influence of potential adverse treatment outcomes and treatment choice; (b) determine whether receipt of a decision aid predicts higher odds of concordance; and (c) identify predictors of concordance from a set of participant characteristics and influential personal factors. Methods Participants reported the influence of potential adverse treatment outcomes and personal factors on treatment decisions at baseline. Preference-concordant treatment was defined as (a) any treatment if risk of adverse outcomes did not have a lot of influence, (b) active surveillance if risk of adverse outcomes had a lot of influence, or (c) radical prostatectomy or active surveillance if risk of adverse bowel outcomes had a lot of influence and risk of other adverse outcomes did not have a lot of influence. Data were analyzed using descriptive statistics and logistic regression. Results Of 224 participants, 137 (61%) pursued treatment concordant with preferences related to adverse treatment outcomes. Receipt of a decision aid did not predict higher odds of concordance. Low tumor risk and age ≥ 60 years predicted higher odds of concordance, while attributing a lot of influence to the impact of treatment on recreation predicted lower odds of concordance. Conclusions Risk of potential adverse treatment outcomes may not be the foremost consideration of some patients with LPC. Assessment of the relative importance of patients’ stated values and preferences is warranted in the setting of LPC treatment decision making.

Abstract
Abstract
Background: Patients with early-stage non-small cell lung cancer (NSCLC) are at substantial risk for disease recurrence after surgical resection, and the discovery of biomarkers that predict disease recurrence has been challenging. We sought to identify genomic and immunologic factors associated with recurrence after surgery in stage I NSCLC.
Methods: We collected clinicopathologic data from patients with resected stage I NSCLC (AJCC 8th Edition) which underwent multiplexed immunofluorescence for CD8+, FOXP3+, PD-1+, and PD-L1. A subset of these samples also had next-generation sequencing performed to identify genomic alterations and tumor mutational burden (TMB). A bidirectional stepwise elimination was applied on variables with a univariable disease-free survival (DFS) p-value <0.25. The final multivariable Cox model was validated with internal bootstrapping (B=300).
Results: A total of 252 cases were included. After a median follow-up of 25.6 months from the time of surgery, 47 cases (18.7%) experienced recurrence, with a 2-year DFS rate of 82.9%, and a 2-year overall survival (OS) rate of 97.9%. Shorter DFS was associated with higher TMB, increased PD-L1 expression, and greater numbers of intratumoral (IT) CD8+, PD-1+, and PD-1+CD8+ immune cells, as well as increased CD8+ and FOXP3+ T cells at the tumor stroma interface (TSI) in univariable analyses (p<0.05). Multivariable analysis showed that shorter DFS was associated with increasing TMB and higher PD-L1 tumor cell expression. We observed a difference by immune cell localization and risk of recurrence: shorter DFS was associated with higher IT but lower TSI PD-1+ immune cells, and higher IT but lower TSI FOXP3+ T cells (Table). Internal bootstrap validation showed good model performance (C-index = 0.74).
Conclusion: Genomic analysis and immunophenotyping of stage I NSCLCs can identify cases at greatest risk of disease recurrence after surgical resection.

Abstract
BackgroundUpadacitinib (UPA, 15 mg QD), an oral JAK1 selective inhibitor, showed greater efficacy compared to adalimumab (ADA, 40 mg EOW) at week 12 in patients with active rheumatoid arthritis (RA) on background methotrexate (MTX) in the SELECT-COMPARE phase 3 study1. Treatment with UPA compared to ADA resulted in a larger proportion of patients reaching CDAI Remission (REM) at week 26 (23% vs. 14%, p-value ≤ 0.001). Because remission is the goal in managing RA, it is of clinical relevance to identify early during the treatment course who might be able to achieve this state. It has been reported that early response to therapy with UPA was associated with achieving CDAI REM at week 262. In parallel, it has been reported that reduction in monocyte can predict DAS28-ESR REM in RA patients treated with anti-TNF therapy3. However, the relative predictive values of clinical and standard laboratory measures have not been compared side-by-side.ObjectivesTo determine post-hoc the relative predictive values of selected clinical and standard laboratory measures collected at week 12 for identifying RA patients who will be in CDAI REM at week 26 upon treatment with UPA or ADA.MethodsClinical (CDAI, SDAI, and DAS28-CRP) and laboratory data (CRP, ESR, CBC with differential, and Lipids) for all available patients enrolled in the SELECT-COMPARE phase 3 study were included in this post-hoc analysis (UPA: n =623 [CDAI REM at wk26 = 23.8%]; ADA: n = 316 [CDAI REM at wk 26 = 14.2%]). Patients who switched treatment between weeks 14 and 22 due to not reaching at least 20% improvement in tender and swollen joints were classified as non-responders for CDAI REM at week 26. The predictive value of clinical and laboratory endpoints recorded at week 12 for determining CDAI REM status at week 26 was assessed by univariate logistic regression. We report the performance of each model as ROC AUC with a cutoff of 0.75 for meaningful predictive value.ResultsFor both patients treated with UPA and those treated with ADA, clinical disease activity status measures (CDAI, SDAI, and DAS28-CRP) and relative change in disease activity measures (Percent Change [PCHG] in CDAI, PCHG in DAS28-CRP, and PCHG in SDAI) at week 12 resulted in the highest predictive performance for determining CDAI REM status at week 26 (Figure 1). In contrast, none of the selected standard laboratory measures (CRP, ESR, CBC with differential, and Lipids) reached a meaningful predictive value (ROC AUC < 0.75). Of note, cell numbers and changes in cell numbers (including Neutrophils Lymphocytes, Basophils, Eosinophils, and Monocytes) at week 12 had no meaningful predictive value for determining CDAI REM at week 26.Figure 1.Univariate Logistic Models to Predict CDAI REM at Week 26 in Active RA Patients who had an Inadequate Response to MTX: ROC Analysis AUC.Legend: All evaluated parameters were recorded at Week 12; CHG = Change from Baseline to Week 12; PCHG = Percent Change from Baseline to Week 12ConclusionThis analysis suggests that standard laboratory measures (CRP, ESR, CBC with differential, and Cholesterol) at week 12 do not represent useful predictors for REM at week 26 in csDMARD-IR RA patients. In particular, blood cell numbers and the changes in these measures at week 12 do not provide additional predictive value in our analyses, contrasting with the results from Amarnani and colleagues3. Hence, clinical disease activity levels and changes in these measures at week 12 remain adequate predictors of CDAI REM at week 26. Still, the absolute predictive performance of clinical measures remains suboptimal, highlighting the need to dedicate continued efforts to identify and validate improved predictors of long-term REM in RA.References[1]Fleischmann, R. et al.

Abstract
Central vascular access devices (CVADs) are often essential to the care of patients undergoing long-term cancer treatment. CVAD maintenance is an essential oncology nurse competency. Evidence-based practice (EBP) in flushing and locking help to prevent intraluminal occlusion, a common complication. Heparinized saline (HS) has been the standard locking solution for CVADs. However, research indicates no superiority of HS over normal saline (NS). The objectives of this EBP project were 1) to evaluate whether a significant difference in intraluminal occlusion was associated with the change from HS to NS use for locking CVADs in ambulatory oncology care, and 2) to evaluate the effects of peer nurse mentoring on nurses’ and patients’ perspectives about the practice change. Analysis of data revealed decreases in alteplase usage after transitioning to NS locking. Patient and nurse surveys indicated that peer nurse mentoring increased nurse and patient confidence and competence in making the practice transition.

Abstract
Les patients recevant un traitement à long terme contre le cancer doivent très souvent se faire poser un cathéter veineux central (CVC). L’entretien du CVC est donc une compétence fondamentale des infirmières en oncologie. Les pratiques d’irrigation et de fermeture du CVC fondées sur la recherche aident à prévenir l’occlusion intraluminale, une complication fréquente. Les normes recommandent l’utilisation d’un soluté physiologique hépariné pour fermer le CVC; toutefois, selon la recherche, le soluté hépariné n’est pas plus efficace que le seul sérum physiologique. Les objectifs du présent projet de pratique fondée sur la recherche étaient : 1) d’évaluer si la fermeture au sérum physiologique plutôt qu’au soluté hépariné était liée à une différence significative du nombre de cas d’occlusion intraluminale chez les patients suivis en clinique d’oncologie externe; et 2) d’évaluer les effets du mentorat entre pairs sur le point de vue des infirmières et des patients quant au changement de pratique. L’analyse des données a révélé une diminution de l’utilisation d’altéplase après l’adoption du sérum physiologique pour fermer les CVC. Les sondages réalisés auprès des patients et des infirmières montrent que le mentorat entre pairs accroît la confiance des infirmières et des patients, ainsi que l’habileté à procéder au changement de pratique.

Study endpoints were symptom burden (pain, fatigue, and bother) at baseline and 5.5 months, non-completion of induction therapy, overall survival (OS) and progression-free survival (PFS). Multivariable logistic and Cox regression examined associations between nSES, AL and patient outcomes. A 1-unit increase in baseline AL was associated with greater odds of high fatigue at baseline (adjusted OR [95% CI] = 1.21 [1.08–1.36]) and a worse OS (adjusted hazard ratio, [95% CI] = 1.21 [1.06–1.37]). High nSES was associated with worse baseline bother (middle OR = 4.22 [1.11–16.09] and high 4.49 [1.16–17.43]) compared to low nSES. There was no association between AL or nSES and symptom burden at 5.5 months, non-completion of induction therapy or PFS. Additionally, there was no association between nSES and OS. AL may have utility as a predictive marker for OS among patients with MM and may allow individualization of treatment. Future studies should standardize and validate AL patients with MM.

Abstract
CONTEXT Clinical guidelines are available to enhance symptom management during cancer treatment but often are not used in the practice setting. Clinical decision support can facilitate the implementation and adherence to clinical guidelines. and improve the quality of cancer care. OBJECTIVES Clinical decision support offers an innovative approach to integrate guideline-based symptom management into oncology care. This study evaluated the effect of clinical decision support-based recommendations on clinical management of symptoms and health-related quality of life (HR-QOL) among outpatients with lung cancer. METHODS Twenty providers and 179 patients were allotted in group randomization to attention control (AC) or Symptom Assessment and Management Intervention (SAMI) arms. SAMI entailed patient-report of symptoms and delivery of recommendations to manage pain, fatigue, dyspnea, depression, and anxiety; AC entailed symptom reporting prior to the visit. Outcomes were collected at baseline, two, four and six-months. Adherence to recommendations was assessed through masked chart review. HR-QOL was measured by the Functional Assessment of Cancer Therapy-Lung questionnaire. Descriptive statistics with linear and logistic regression accounting for the clustering structure of the design and a modified chi-square test were used for analyses. RESULTS Median age of patients was 63 years, 58% female, 88% white, and 32% ≤high school education. Significant differences in clinical management were evident in SAMI vs. AC for all target symptoms that passed threshold. Patients in SAMI were more likely to receive sustained-release opioids for constant pain, adjuvant medications for neuropathic pain, opioids for dyspnea, stimulants for fatigue and mental health referrals for anxiety. However, there were no statistically significant differences in HR-QOL at any time point. CONCLUSION SAMI improved clinical management for all target symptoms but did not improve patient outcomes. A larger study is warranted to evaluate effectiveness.

Abstract
BACKGROUND Previous studies have shown that lipid accumulation product (LAP) was associated with the risk of cardiometabolic disease. It is not clear whether LAP could be used as a marker to identify metabolic syndrome (MetS) among Chinese ethnic groups. AIM To assess the reliability of LAP as a maker to identify MetS among Dong adults. DESIGN Population-based cross-sectional study. METHOD We included 6494 Dong individuals (1403 patients) aged 30-79 years from southwest China. MetS was established by Chinese Diabetes Society. Logistic regression model was utilized to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Receiver operating characteristic (ROC) curve was utilized to calculate area under the ROC curve (AUC) and 95% CIs to obtain the identification ability for MetS. RESULTS The risk of MetS was increased with per 5 units increase of LAP (OR 1.37 [95% CI, 1.34-1.39]). Similar results were found in subgroup analyses and sensitivity analyses. Clustered metabolic risk associated with per 5 units increase of LAP was observed for people with 1 (OR 1.59 [95% CI, 1.53-1.65]), 2 (2.15 [2.06-2.24]), 3 (2.59 [2.48-2.71]), 4 (2.81 [2.69-2.95]) and 5 (3.03 [2.87-3.21]) MetS components. LAP presented higher AUC (0.915 [95% CI, 0.907-0.923]) than other included obesity indices (P < 0.05). CONCLUSION These data support evidence that LAP was related to the risk of MetS, had a high AUC and could be a reliable index for identifying MetS patients among Dong adults in Chinese.

Abstract
RAS family members are the most frequently mutated oncogenes in human cancers. Although KRAS(G12C)-specific inhibitors show clinical activity in patients with cancer1-3, there are no direct inhibitors of NRAS, HRAS or non-G12C KRAS variants. Here we uncover the requirement of the silent KRASG60G mutation for cells to produce a functional KRAS(Q61K). In the absence of this G60G mutation in KRASQ61K, a cryptic splice donor site is formed, promoting alternative splicing and premature protein termination. A G60G silent mutation eliminates the splice donor site, yielding a functional KRAS(Q61K) variant. We detected a concordance of KRASQ61K and a G60G/A59A silent mutation in three independent pan-cancer cohorts. The region around RAS Q61 is enriched in exonic splicing enhancer (ESE) motifs and we designed mutant-specific oligonucleotides to interfere with ESE-mediated splicing, rendering the RAS(Q61) protein non-functional in a mutant-selective manner. The induction of aberrant splicing by antisense oligonucleotides demonstrated therapeutic effects in vitro and in vivo. By studying the splicing necessary for a functional KRAS(Q61K), we uncover a mutant-selective treatment strategy for RASQ61 cancer and expose a mutant-specific vulnerability, which could potentially be exploited for therapy in other genetic contexts.

Abstract
PURPOSE Previous studies have not fully described the relationship between high-density lipoprotein cholesterol (HDL-C) and death risks from all cause and cardiovascular disease (CVD). This study quantitatively evaluates HDL-C-mortality associations. METHODS Embase and PubMed databases were searched for relevant articles published up to 1 June 2019. Random-effects models were used to pool relative risks (RRs) and 95% confidence intervals (CIs). We used restricted cubic splines to model the dose-response association. RESULTS We identified 32 prospective cohort studies including 369,904 participants and 33,473 total deaths (9426 CVD deaths). Compared to the lowest HDL-C levels, all cause and CVD mortality risks were reduced by 18% (RR 0.82; 95% CI, 0.73-0.93) and 36% (0.64, 0.46-0.89), respectively, for the highest HDL-C levels. All cause and CVD mortality risks were reduced by 15% (0.85, 0.79-0.92) and 23% (0.77, 0.69-0.87), respectively, with each 1 mmol/L increment of HDL-C. We found evidence of nonlinear and negative dose-response associations of HDL-C with all cause and CVD mortality (Pnonlinearity < 0.001), and the lowest death risks from all cause and CVD were observed at approximately 1.34 and 1.55 mmol/L, respectively. CONCLUSION HDL-C is inversely associated with all cause and CVD mortality risks under approximately 2.05 and 2.33 mmol/L, respectively. Optimal doses require investigation via clinical practice or high-quality research.

Abstract
BACKGROUND The early identification of chemotherapy-induced peripheral neuropathy (CIPN) (e.g., numbness or tingling in the fingers or toes) is important due to its frequency and the few effective treatment options available. The identification of common patient-reported CIPN characteristics and associated functional limitations may help to facilitate patient-clinician discussions of CIPN in practice. AIMS To quantify the severity, duration, location, characteristics, and associated functional limitations of chemotherapy-induced peripheral neuropathy (CIPN) in patients receiving neurotoxic chemotherapy. DESIGN Exploratory secondary analysis of a prospective, two-phase study SETTING: Breast, gastrointestinal, and multiple myeloma clinics at Dana-Farber Cancer Institute. PARTICIPANTS 142 individuals who planned to receive at least three more cycles of neurotoxic chemotherapy after consent. METHODS Participants self-reported CIPN using standardized measures (i.e., PRO-CTCAE™ Numbness and Tingling Items or 0-10 numerical rating scale of worst CIPN pain intensity) and/or study team generated follow up questions about CIPN location, duration, characteristics, and functional limitations prior to three consecutive clinic visits (T1, T2, T3). Participants' responses to the CIPN self-report questionnaires were described by chemotherapy type and age. RESULTS Over approximately 36.5 days (T1-T3), the percentage of participants reporting at least mild CIPN increased from 59.3% to 71%. At T3, patients with non-painful (n = 98) or painful neuropathy (n = 34) frequently reported symptoms in the fingers (non-painful = 83.5%, painful = 76.5%) or toes (non-painful = 49.5%, painful = 41.2%) and characterized symptoms as numbness (non-painful = 54.1%, painful = 50%) or tingling (non-painful = 68.4%, painful = 82.4%). Self-reported CIPN functional limitations (n = 55) included difficulties with buttoning a shirt (38.2%) or walking (25.5%). Paclitaxel-related CIPN (n = 33) was frequently characterized as "continuous" (30.3%), whereas oxaliplatin-related CIPN (n = 51) was frequently characterized as "intermittent" (41.2%). Young adults (15-39 years old, n = 15) frequently reported moderate-severe non-painful CIPN (46.7%), painful CIPN (40%), and CIPN interference (33.3%). CONCLUSIONS Consistent with qualitative research, participants frequently described CIPN as numbness and/or tingling in the fingers and/or toes.

Abstract
MET targeted therapies are clinically effective in MET amplified and MET exon 14 deletion mutant (METex14) non-small cell lung cancers (NSCLC) but their efficacy is limited by the development of drug resistance. Structurally distinct MET tyrosine kinase inhibitors (TKIs) (type I/II) have been developed or are under clinical evaluation, which may overcome MET mediated drug resistance mechanisms. In this study, we assess secondary MET mutations likely to emerge in response to treatment with single-agent or combinations of type I/type II MET TKIs using TPR-MET transformed Ba/F3 cell mutagenesis assays. We found that these inhibitors gave rise to distinct secondary MET mutant profiles. However, a combination of type I/II TKI inhibitors (capmatinib and merestinib) yielded no resistant clones in vitro. The combination of capmatinib/merestinib was evaluated in vivo and led to a significant reduction in tumor outgrowth compared to either MET inhibitor alone. Our findings demonstrate in vitro and in vivo that a simultaneous treatment with a type I and type II MET TKI may be a clinically viable approach to delay and/or diminish the emergence of on target MET mediated drug resistance mutations.

Abstract
OBJECTIVE To describe perceptions of patient-centered communication (PCC); assess whether physician specialty, patient characteristics, or health system characteristics are associated with PCC; and identify associations between PCC, health-related quality of life (HRQoL), and symptom burden among individuals with ovarian cancer. METHODS Cross-sectional, descriptive survey of English-speaking adults with ovarian cancer. PCC, HRQoL, and ovarian cancer symptom burden were assessed with the PCC-Ca-36, the FACT-G, and the FOSI-18, respectively. PCC-Ca-36 scores were summarized using descriptive statistics. Predictors of PCC-Ca-36, FACT-G, and FOSI-18 scores were identified using multiple linear regression. RESULTS Participants (n = 176) had a mean age of 59.4 years (SD = 12.1). The majority (65.9%) had advanced-stage disease, while 42.0% were receiving treatment. The mean PCC-Ca-36 total score was 4.09 (SD = 0.78) out of a possible 5, indicating participants often perceived that clinicians engaged in PCC. Among the PCC functions, participants reported that clinicians least often enabled patient self-management (M = 3.65, SD = 0.99), responded to emotions (M = 3.84, SD = 1.04), and managed uncertainty (M = 3.91, SD = 0.93). In multivariable analyses, neither physician specialty nor patient and health system characteristics were significantly associated with overall PCC. Greater overall PCC predicted better overall HRQoL; better social/family, emotional, and functional well-being; and lower overall and physical symptom burden (all p ≤ 0.05). CONCLUSION Greater PCC is significantly associated with better HRQoL and lower symptom burden among individuals with ovarian cancer. PRACTICE IMPLICATIONS Promotion of PCC is a promising strategy to improve patient-reported outcomes in the ovarian cancer care setting.

Abstract
In a comparative oncology study with progression-free or overall survival as the endpoint, the primary or key secondary analysis is routinely stratified by patients' baseline characteristics when evaluating the treatment difference. The validity of a conventional strategy such as a stratified HR analysis depends on stringent model assumptions that are unlikely to be met in practice, especially in immunotherapy studies. Thus, the resulting summary is generally neither valid nor interpretable. This article discusses issues with conventional stratified analyses and presents alternatives using data from KEYNOTE-189, a recent immunotherapy trial for treating patients with metastatic, non-squamous, non-small-cell lung cancer.

Abstract
Introduction Remote consent and enrollment offer a unique opportunity to provide rare cancer populations with access to clinical research. The genomic analysis of plasma cell-free DNA (cfDNA) permits remote characterization of the cancer genome. We hypothesized we could leverage these approaches to remotely study drug resistance in patients with metastatic ALK-positive NSCLC. Methods The SPACEWALK study (Study of Plasma Next-Generation Sequencing for Remote Assessment, Characterization, Evaluation of Patients With ALK Drug Resistance) enrolled patients with ALK-positive NSCLC and progression on a next-generation ALK inhibitor who could participate remotely. Plasma was collected for next-generation sequencing (NGS) of cfDNA before initiating subsequent therapy, with results returned and subsequent therapy studied. Results Of the 62 patients enrolled, an ALK fusion was detected in 27 (44%) with a median allelic fraction of 2.6%. Among these 27 patients, a potential resistance mechanism was identified in 17 patients (63%): eight cases (30%) had secondary ALK kinase domain resistance mutations, three cases (11%) had bypass track resistance, and six cases (22%) had both ALK resistance mutations and bypass resistance. The most frequently detected mechanism of bypass resistance was MET amplification. Repeat plasma NGS was performed in 14 patients after subsequent treatment was initiated, with seven (50%) patients exhibiting greater than 50% reductions in ALK fusion allelic fraction. Conclusions Through the leveraging of remote participation, plasma NGS offers an optimal mechanism for characterizing resistance to emerging targeted therapies in rare cancer populations, though sensitivity depends on adequate tumor DNA samples. Repeat cfDNA analysis on therapy may offer an objective monitoring approach to remotely study treatment response.

Abstract
BACKGROUND Timely detection of chemotherapy-induced peripheral neuropathy (CIPN) is critical to effectively tailor chemotherapy dose levels and offer supportive care. The purpose of this secondary analysis was to determine the reliability and validity of the two Patient-Reported Outcomes Version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE™) numbness and tingling severity and interference items to screen for CIPN in patients receiving taxanes, platinums, or proteasome inhibitors. METHODS Participants (N = 142) completed the two PRO-CTCAE items, a 0-10 numerical rating scale of worst CIPN pain intensity, and the Quality of Life Questionnaire-CIPN20 (QLQ-CIPN20) prior to three clinical visits (T1, T2, T3) during neurotoxic chemotherapy. Participants completed the two PRO-CTCAE items again following the T3 clinical visit (T4). In addition, study staff administered the modified Total Neuropathy Score-Clinical Version (TNSc©) at T3. We examined floor (i.e., no CIPN severity or interference) and ceiling effects, test-retest reliability, concurrent validity, longitudinal validity, construct validity of the response categories, and sensitivity and specificity of the two PRO-CTCAE items. RESULTS At T3, 29% of participants had PRO-CTCAE severity scores at the floor; 60.1% of participants reported interference item scores at the floor. Agreements between scores reported at T3 and T4 for PRO-CTCAE severity (ICC = 0.79) and interference (ICC = 0.73) were moderate to strong. The PRO-CTCAE severity and interference items correlated moderately-strongly with QLQ-CIPN20 sensory (Spearman's ρ-range = 0.53-0.72) and motor (Spearman's ρ-range = 0.50-0.58) subscale scores. The Cohen's d from T1 to T3 for the PRO-CTCAE items were small (severity: d = 0.32, interference: d = 0.40) and comparable to the effect sizes for change observed with the QLQ-CIPN20. The PRO-CTCAE severity (0-3) and interference (0-2) response categories distinguished respondents with significantly different levels of QLQ-CIPN20 sensory and motor subscale scores (p < 0.001 via Jonckheere-Terpstra tests). The sensitivity and specificity of the PRO-CTCAE severity item (cutoff > 0) to detect probable sensory peripheral neuropathy were 95.83% and 65.22%, while the sensitivity and specificity of the PRO-CTCAE™ interference item (cutoff > 0) were 51.39% and 73.91%. CONCLUSION Preliminary evidence supports the reliability and validity of the PRO-CTCAE numbness and tingling items for CIPN screening, although there may be floor effects and limitations in the capacity of the PRO-CTCAE items to identify the full range of CIPN sensory and motor features beyond numbness and tingling.

Abstract
Objective: Establishment of a new model of human primary colon cancer transplantation tumor in normal immune mice and to provide a reliable experimental animal model for studying the pathogenesis of colon cancer under normal immunity. Methods: Human colon cancer cells come from colon cancer patients who underwent surgery in the Affiliated Hospital of Jining Medical College in 2017. The mice in the cell control group were inoculated with phosphate buffered solution (PBS) containing colon cancer cells, the microcarrier control group was inoculated with PBS containing microcarrier 6, and the cell-microcarrier complex group was inoculated with the PBS containing colon cancer cell-microcarrier complex. The cells of each group were inoculated under the skin of the right axilla of mice by subcutaneous injection, and the time, size, tumor formation rate and pathological changes under microscope were recorded. The transplanted tumor tissue was immunohistochemically stained with the EnVisiion two-step method, and the tumor formation rate of the transplanted tumor was judged according to the proportion of positive cells in the visual field. The polymerase chain reaction (PCR) method was used to detect the expression of human-specific Alu sequence in mice tumor tissue. Results: After inoculation with tumor cells, the mice in the cell control group and the microcarrier control group did not die and did not form tumors; the mice in the cell-microcarrier complex group had palpable subcutaneous tumors in the right axillary subcutaneously on the 5th to 7th days after inoculation, and tumor formation rate is 67% (10/15), and the tumor volume can reach about 500 mm(3) 2 to 3 weeks after vaccination. The immunohistochemistry results showed that CK20, CDX-2 and carcinoembryonic antigen were all positively expressed. The PCR results showed that the expression of human-specific Alu sequence can be detected in the transplanted tumor tissue of tumor-bearing mice. Conclusion: Human primary colon cancer cells used microcarrier 6 as a carrier to form tumors in normal immunized mice, and successfully established a new model of human colon cancer transplantation tumor in normal immune mice.

Abstract
BACKGROUND Patients 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. METHODS We 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. RESULTS Among 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). CONCLUSIONS A 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
Small cell lung carcinoma (SCLC) is highly mutated, yet durable response to immune checkpoint blockade (ICB) is rare. SCLC also exhibits cellular plasticity, which could influence its immunobiology. Here we discover that a distinct subset of SCLC uniquely upregulates MHC I, enriching for durable ICB benefit. In vitro modeling confirms epigenetic recovery of MHC I in SCLC following loss of neuroendocrine differentiation, which tracks with derepression of STING. Transient EZH2 inhibition expands these nonneuroendocrine cells, which display intrinsic innate immune signaling and basally restored antigen presentation. Consistent with these findings, murine nonneuroendocrine SCLC tumors are rejected in a syngeneic model, with clonal expansion of immunodominant effector CD8 T cells. Therapeutically, EZH2 inhibition followed by STING agonism enhances T-cell recognition and rejection of SCLC in mice. Together, these data identify MHC I as a novel biomarker of SCLC immune responsiveness and suggest novel immunotherapeutic approaches to co-opt SCLC's intrinsic immunogenicity. SIGNIFICANCE: SCLC is poorly immunogenic, displaying modest ICB responsiveness with rare durable activity. In profiling its plasticity, we uncover intrinsically immunogenic MHC Ihi subpopulations of nonneuroendocrine SCLC associated with durable ICB benefit. We also find that combined EZH2 inhibition and STING agonism uncovers this cell state, priming cells for immune rejection.This article is highlighted in the In This Issue feature, p. 1861.

Abstract
12102 Background: Allostatic load (AL) conceptualizes the effects of chronic psychosocial adversity on physiologic dysregulation. To date, studies have shown an association between elevated AL and higher disease-specific and overall mortality among cancer patients; however, none have focused on multiple myeloma (MM) patients. We aim to understand the relationship between baseline AL, symptom burden, and mortality among patients enrolled in the E1A11 therapeutic trial in MM. Methods: ECOG-ACRIN E1A11 was a phase III RCT comparing induction with Bortezomib (Arm A) versus Carfilzomib (Arm B) in conjunction with Lenalidomide +Dexamethasone. AL included 7 biomarkers: BMI, alkaline phosphatase, creatinine, C-reactive protein, white blood cell count, albumin and creatinine clearance. AL7 was a composite summary score with a point was assigned for each biomarker value in the highest quartile, except for albumin and creatinine clearance, where a point was assigned for values in the lowest quartile. Endpoints included symptom burden at baseline and ̃1 month, non-completion of induction therapy, and overall survival (OS). Functional Assessment of Cancer Therapy Multiple Myeloma (FACT-MM) items assessed patient-reported symptom burden, including fatigue (item HI7), pain (GP4), and bother by side effects of treatment (GP5) on a 5-point Likert scale. Multivariable logistic regressions assessed the effect of AL7 (ranging 0-7) on high-pain, -fatigue, and -bother (QOL score > = 3 vs < 3), and non-completion of induction therapy. The effect of AL7 on OS was assessed using multivariable Cox regression. Regression covariates included study arm, age, sex, race, ECOG performance status, and the target symptom burden score at baseline. Results: The study cohort included 1087 patients. Mean baseline AL7 was 1.8 (±1.4). In adjusted analysis, a unit increase in AL7 was associated with a greater odds of high pain (OR 1.15, 95%CI [1.04-1.27]) and high fatigue (OR 1.19, 95%CI [1.07-1.32]) at baseline, which did not persist at ̃1 month (pain OR 0.96, 95%CI [0.84-1.10]; fatigue OR 1.03, 95%CI [0.91-1.16]). There was no association between AL7 and high side effect bother at baseline (OR 1.06, 95% CI [0.83-1.35]) or at ̃1 month (OR 1.06, 95%CI [0.90-1.24]). There was no association between AL7 and induction non-completion (OR 1.07, 95%CI [0.96-1.18]). Notably, each unit increase in AL7 was associated with higher mortality (HR 1.26, 95%CI [1.14-1.39]). Conclusions: Despite its association with fatigue and pain at baseline, AL7 was not associated with these symptoms at ̃1 month nor induction non-completion. However, elevated baseline AL7 was associated with poorer OS. AL composite score at baseline, which we interpret as a measure of physiological dysregulation associated with adverse social factors, may have implications on clinical outcomes within clinical trials despite presumed equal treatment access.
