RESUMO
INTRODUCTION: Cardiotoxicity, manifest by reduced left ventricular ejection fraction (LVEF), is the most common reason for the premature discontinuation of trastuzumab. While permissive cardiotoxicity (where mild cardiotoxicity is accepted to enable ongoing trastuzumab) has been shown feasible, the longer-term outcomes are unknown. We aimed to study the intermediate-term clinical outcomes of patients who underwent permissive cardiotoxicity. MATERIALS AND METHODS: We performed a retrospective cohort study of patients referred to the cardio-oncology service at McMaster University from 2016 to 2021 for LV dysfunction following trastuzumab administration. RESULTS: Fifty-one patients underwent permissive cardiotoxicity. The median (25th-75th percentile) follow-up time from cardiotoxicity onset was 3 years (1.3-4 years). Forty-seven (92%) patients completed trastuzumab; 3 (6%) developed severe LV dysfunction or clinical heart failure (HF) while on trastuzumab and prematurely discontinued therapy. One discontinued trastuzumab by patient choice. At final follow-up after therapy completion, 7 (14%) patients still had mild cardiotoxicity, including 2 who had clinical heart failure and stopped trastuzumab early. Among those with recovered LV function, 50% had normalized LVEF or GLS by 6 and 3 months, respectively, after initial cardiotoxicity. There was no difference in characteristics between those who did or did not recover their LV function. CONCLUSIONS: Among patients exposed to permissive trastuzumab cardiotoxicity for HER2-positive breast cancer, 6% were unable to complete planned trastuzumab due to severe LV dysfunction or clinical HF. Although most patients recover their LV function after trastuzumab discontinuation or completion, 14% still have persistent cardiotoxicity by 3-year follow-up.

BACKGROUND: Complementary medicines (CM) are frequently used by patients with cancer. Controversy exists over the effectiveness and risk that CM may add to conventional cancer therapy. The incidence of CM use among patients enrolled in phase III clinical trials is unknown. METHODS: Medication lists from 6 international phase III clinical trials were retrospectively reviewed to identify patients using CM. Patients had metastatic breast, colorectal, or lung cancers. Quality of life, adverse events, overall survival, and progression-free survival were compared between CM users and non-users. Baseline differences between groups were adjusted with propensity score matching groups. RESULTS: Seven hundred and six of 3446 patients (20.5%) used at least one CM. CM use was highest among patients with breast cancer (35.6%). CM users had more favorable baseline prognostic factors (ECOG 0-1, non-smoking status, younger age, and fewer metastases). CM use was associated with lower rates of adverse events (50% vs. 62%, P = .002) and quality of life was similar between both groups. After adjustment with propensity score matching, CM use was also associated with longer overall survival in patients with lung cancer (adjusted hazard ratio 0.80, 95%CI, 0.68-0.94, P =.0054). However, several key control variables like EGFR status were not available. CONCLUSION: One in 5 patients in phase III clinical trials report using CM. CM was not associated with worse cancer-specific outcomes. However, CM users had more favorable baseline prognostic factors, and likely other confounders that may have contributed to improved outcomes observed in the lung cohort. Physicians should monitor for CM use and potential interactions with clinical trial drugs.

Trastuzumab is an effective treatment for HER2-positive breast cancer. Current guidelines recommend withholding trastuzumab in patients experiencing a significant asymptomatic decline in left ventricular function. In this commentary, we discuss the survival benefits afforded by trastuzumab juxtaposed against the risk of trastuzumab-mediated cardiotoxicity. It is not known whether the net benefit of continuing trastuzumab in the setting of mild cardiotoxicity outweighs the associated risks. We describe a potential approach undertaken by our group, and others, and call for a randomized trial.

BACKGROUND: We examined clinical outcomes in a population-based cohort of EGFR mutant advanced NSCLC patients, exploring the potential role of factors including tumour EGFR mutation fraction and cellularity in predicting outcomes. METHODS: A cohort of patients with EGFR mutant advanced NSCLC was identified (N =2 93); clinical outcomes, pathologic and treatment details were collected. Tumour response was determined from radiology and clinical notes. Association between demographic and pathologic variables EGFR TKI response, time to treatment failure (TTF) and overall survival (OS) was examined using logistic regression and proportional hazards regression. EGFR TKI response rates were summarised by percent mutation fraction to explore their association. RESULTS: Higher mutation fraction was associated with greater EGFR TKI response rate (odds ratio 1.58, 95% CI = 1.21-2.07, P = 0.0008), longer TTF (hazard ratio 0.80, 95% CI = 0.68-0.92, P = 0.003) and better OS (hazard ratio 0.81, 95% CI = 0.67-0.99, P = 0.04). However, even in patients with ⩽ 5% mutation fraction, response rate was 34%. Females had longer TTF (P = 0.02). CONCLUSIONS: EGFR mutation fraction in tumour samples was significantly associated with response, TTF and OS. Despite this, no lower level of mutation fraction was detected for which EGFR TKI should be withheld in those with activating EGFR mutations.

Upregulation of angiogenesis is a frequent occurrence in lung cancer and is reported to represent a negative prognostic factor. This provides a rationale for the development and evaluation of anti-angiogenic agents. To date bevacizumab, a monoclonal antibody directed against serum VEGF, is the only anti-angiogenic agent that has demonstrated improved overall survival for patients with lung cancer. Meta-analysis of trials of bevacizumab in combination with platinum-based chemotherapy for NSCLC, show a 10% reduction in the risk of death (HR 0.90, 95% CI 0.81-0.99). However, therapy with bevacizumab is limited to NSCLC patients with non-squamous histology, good performance status, no brain metastases and the absence of bleeding or thrombotic disorders. More recently, similar survival was observed in a non bevacizumab containing regimen of carboplatin, pemetrexed and maintenance pemetrexed. Multiple oral anti-angiogenic compounds have been evaluated in NSCLC, both in first-line therapy, or upon disease progression. The majority of agents have shown some evidence of activity, but none have clearly demonstrated improvements in overall survival. Increased toxicities have been observed, including an increased risk of death for some agents, limiting their development. Promising data exist for sunitinib in patients with heavily pre-treated NSCLC, and nintedanib in combination with docetaxel, as second-line therapy for NSCLC. However, these findings require validation. Currently, there is no established role for anti-angiogenic therapy in SCLC, although there is some promise for sunitinib as maintenance therapy following platinum and etoposide chemotherapy. The challenge for anti-angiogenic therapy is to understand whether treatment effects in a subpopulation, are lost among a larger unselected population of patients. There is a need for additional translational research to identify predictive biomarkers for anti-angiogenic therapy.

BACKGROUND: Dacomitinib is an irreversible pan-HER tyrosine-kinase inhibitor with preclinical and clinical evidence of activity in non-small-cell lung cancer. We designed BR.26 to assess whether dacomitinib improved overall survival in heavily pretreated patients with this disease. METHODS: In this double-blind, randomised, placebo-controlled, phase 3 trial, we enrolled adults (aged ≥18 years) with advanced or metastatic non-small-cell lung cancer from 75 centres in 12 countries. Eligible patients had received up to three previous lines of chemotherapy and either gefitinib or erlotinib, and had assessable disease (RECIST 1.1) and tumour tissue samples for translational studies. Patients were stratified according to centre, performance status, tobacco use, best response to previous EGFR tyrosine-kinase inhibitor, weight loss within the previous 3 months, and ethnicity, and were then randomly allocated 2:1 to oral dacomitinib 45 mg once-daily or matched placebo centrally via a web-based system. Treatment continued until disease progression or unacceptable toxicity. The primary outcome was overall survival in the intention-to-treat population; secondary outcomes included overall survival in predefined molecular subgroups, progression-free survival, the proportion of patients who achieved an objective response, safety, and quality of life. This study is completed, although follow-up is ongoing for patients on treatment. This study is registered with ClinicalTrials.gov, number NCT01000025. FINDINGS: Between Dec 23, 2009, and June 11, 2013, we randomly assigned 480 patients to dacomitinib and 240 patients to placebo. At the final analysis (January, 2014), median follow-up was 23·4 months (IQR 15·6-29·6) for patients in the dacomitinib group and 24·4 months (11·5-38·9) for those in the placebo group. Dacomitinib did not improve overall survival compared with placebo (median 6·83 months [95% CI 6·08-7·49] for dacomitinib vs 6·31 months [5·32-7·52] for placebo; hazard ratio [HR] 1·00 [95% CI 0·83-1·21]; p=0·506). However, patients in the dacomitinib group had longer progression-free survival than those in the placebo group (median 2·66 months [1·91-3·32] vs 1·38 months [0·99-1·74], respectively; HR 0·66 [95% CI 0·55-0·79]; p<0·0001), and a significantly greater proportion of patients in the dacomitinb group achieved an objective response than in the placebo group (34 [7%] of 480 patients vs three [1%] of 240 patients, respectively; p=0·001). Compared with placebo, the effect of dacomitinib on overall survival seemed similar in patients with EGFR-mutation-positive tumours (HR 0·98, 95% CI 0·67-1·44) and EGFR wild-type tumours (0·93, 0·71-1·21; pinteraction=0·69). However, we noted qualitative differences in the effect of dacomitinib on overall survival for patients with KRAS-mutation-positive tumours (2·10, 1·05-4·22) and patients with KRAS wild-type tumours (0·79, 0·61-1·03; pinteraction=0·08). Compared with placebo, patients allocated dacomitinib had significantly longer time to deterioration of cough (p<0·0001), dyspnoea (p=0·049), and pain (p=0·041). 185 (39%) of 477 patients who received dacomitinib and 86 (36%) of 239 patients who received placebo had serious adverse events. The most common grade 3-4 adverse events were diarrhoea (59 [12%] patients on dacomitinib vs no controls), acneiform rash (48 [10%] vs one [<1%]), oral mucositis (16 [3%] vs none), and fatigue (13 [3%] vs four [2%]). INTERPRETATION: Dacomitinib did not increase overall survival and cannot be recommended for treatment of patients with advanced non-small-cell lung cancer previously treated with chemotherapy and an EGFR tyrosine-kinase inhibitor.

PURPOSE: This study aimed to describe the perceptions of women with early stage breast cancer regarding their involvement in treatment decision making (TDM). METHODS: Eligible women with early stage breast cancer were recruited immediately after their first consultation with a specialist. Semistructured personal interviews were held prior to treatment. Interviews were audiotaped, transcribed, and analyzed. RESULTS: Nineteen women with early stage breast cancer considering surgery (n = 6) or adjuvant therapy (n = 13) participated. Women described being involved in various stages of TDM and interacting with informal networks and specialists. Women's descriptions suggest that (1) the concept of involvement in TDM may have a broader meaning for patients than strictly their decisional role and (2) inclusion of significant others in TDM contributes to the patient's sense of involvement. CONCLUSIONS: Conceptualization and measurement of patient involvement in TDM have often been framed within the context of the medical encounter and the patient's perceived or actual role in this process. Our findings raise questions about what involvement means to patients with early stage breast cancer and suggest that the focus on patient involvement in TDM within the medical encounter may be too narrow to capture the meaning of involvement from the patient's perspective.

OBJECTIVE: To identify patients' and physicians' perceptions of physician-related verbal and nonverbal facilitators and barriers to patient involvement in treatment decision making (TDM) occurring during clinical encounters for women with early stage breast cancer (ESBC). METHODS: Eligible women were offered treatment options including surgery and adjuvant therapy. Eligible physicians provided care for women with ESBC in either a teaching hospital or an academic cancer centre. In Phase 1, women were interviewed 1-2 weeks after their initial consultation. In Phase 2, women and their physicians were interviewed separately while watching their own consultation on a digital video disk. All interviews were audiotaped, transcribed and analysed. RESULTS: Forty women with ESBC and six physicians participated. Patients and physicians identified thirteen categories of physician facilitators of women's involvement. Of these, seven categories were frequently identified by women: conveyed a rationale for patient involvement in TDM; explained the risk of cancer recurrence; explained treatment options; enhanced patient understanding of information; gave time for TDM; offered a treatment recommendation; and made women feel comfortable. Physicians described similar information-giving facilitators but less often mentioned other facilitators. Few physician barriers to women's involvement in TDM were identified. CONCLUSIONS: Women with ESBC and cancer physicians shared some views of how physicians involve patients in TDM, although there were important differences. Physicians may underestimate the importance that women's place on understanding the rationale for their involvement in TDM and on feeling comfortable during the consultation.

Patients with colorectal cancer (CRC) face a number of challenges leading up to diagnosis; however, research is limited regarding their specific needs during the pre-diagnosis period. A multicenter cross-sectional survey was conducted to elicit information about the CRC experience during the pre-diagnosis phase. Across the three sites, 104 eligible patients were approached, and 82 patients completed the survey, for a total response rate of 78.9%. The needs most identified by participants during the pre-diagnosis period were informational (31.6%) and emotional (20.3%) needs; social needs were rated as the least important need for these patients (7%). The majority (84.0%) reported that these needs were met. Participants reported feeling shocked or overwhelmed on learning of their diagnosis (57.1%) and high levels of anxiety during this time (40.0%). The majority (77.9%) of participants reported that they were not directed to any resources to help address their anxiety. Informational and emotional needs are identified as the most important needs during the pre-diagnosis phase, and for most these needs are being met; however, some participants are experiencing high levels of anxiety without access to appropriate resources. Further work is required to understand the optimal mechanisms to address identified needs during this pre-diagnosis period and to assess the potential benefits and costs of addressing these needs.

BACKGROUND: Stage III nonsmall cell lung cancer (NSCLC) represents a heterogeneous group of patients. Many patients are treated with curative intent multimodality therapy, either surgical resection plus systemic therapy or chemoradiation plus immunotherapy. However, many patients are not suitable for curative intent therapy and are treated with palliative systemic therapy or best supportive care. METHODS: This paper is a review of recent advances in the management of patients with curative intent disease. RESULTS: There have been significant advances in curative intent therapy for patients with stage III NSCLC in recent years. These include both adjuvant and neoadjuvant systemic therapies. For patients with resectable NSCLC, two trials have demonstrated that adjuvant atezolizumab or pembrolizumab, following chemotherapy, significantly improved disease-free survival (DFS). In patients with tumours harbouring a common mutation of the EGFR gene, adjuvant osimertinib therapy was associated with a large improvement in both DFS and overall survival (OS). Five randomized trials have evaluated chemotherapy plus nivolumab, pembrolizumab, durvalumab, or toripalimab, either as neoadjuvant or perioperative (neoadjuvant plus adjuvant) therapy. All five trials show significant improvements in the rate of pathologic complete response (pCR) and event-free survival (EFS). OS data are currently immature. This would now be considered the standard of care for resectable stage III NSCLC. The addition of durvalumab to chemoradiation has also become the standard of care in unresectable stage III NSCLC. One year of consolidation durvalumab following concurrent chemoradiation has demonstrated significant improvements in both progression-free and overall survival. CONCLUSIONS: Immune checkpoint inhibitor (ICI) therapy has become a standard recommendation in curative intent therapy for stage III NSCLC.

INTRODUCTION: Thymic epithelial tumors are rare and are classified as thymoma, thymic carcinoma, and thymic neuroendocrine tumors. The objective of this systematic review was to evaluate the treatment options for patients with thymic epithelial tumors. METHODS: This systematic review was developed by Ontario Health (Cancer Care Ontario)'s Program in Evidence-Based Care and by the Lung Cancer Disease Site Group. MEDLINE, EMBASE, and the Cochrane Library were searched for studies comparing surgical, radiotherapy, or systemic treatments against any combination of these treatments in patients with thymic epithelial tumors. Meta-analyses were conducted with clinically homogenous studies. RESULTS: A total of 106 studies were included, mainly from observational studies. There was an overall survival benefit with postoperative radiotherapy for patients with thymic carcinoma (hazard ratio = 0.65, 95% confidence interval: 0.47-0.89) and for patients with thymoma (hazard ratio = 0.70, 95% confidence interval: 0.59-0.82), especially for those with a high risk for mortality. Patients with thymic carcinoma or thymoma had a response to chemotherapy. Selection bias affected the results for studies that evaluated neoadjuvant chemotherapy or minimally invasive surgical techniques. Furthermore, the overall survival benefit found for adjuvant chemotherapy may have been confounded by the administration of postoperative radiotherapy. CONCLUSIONS: For patients with thymoma or thymic carcinoma, the literature is of low quality and subject to bias. There were overall survival benefits with postoperative radiotherapy. The results of this systematic review were used to inform treatment recommendations in a clinical practice guideline. Future large-scale prospective studies that control for confounders are needed.

Invasive cardiac interventions are recommended to treat ST-segment elevation myocardial infarction, non-ST-segment elevation acute coronary syndromes, multivessel coronary disease, severe symptomatic aortic stenosis, and cardiomyopathy. These recommendations are based on randomized controlled trials that historically included few individuals with active, advanced malignancies. Advanced malignancies represent a significant competing risk for mortality, and there is limited evidence to inform the risks and benefits of invasive cardiac interventions in affected patients. We review the benefit conferred by invasive cardiac interventions; the periprocedural considerations; the contemporary survival expectations of patients across several types of active, advanced malignancy; and the literature on cardiovascular interventions in these populations. Our objective is to develop a rational framework to guide clinical recommendations on the use of invasive cardiac interventions in patients with active, advanced cancer.
RESUMO
Small-cell lung cancer (SCLC) is an aggressive, neuroendocrine tumour with high relapse rates, and significant morbidity and mortality. Apart from advances in radiation therapy, progress in the systemic treatment of SCLC had been stagnant for over three decades despite multiple attempts to develop alternative therapeutic options that could improve responses and survival. Recent promising developments in first-line and subsequent therapeutic approaches prompted a Canadian Expert Panel to convene to review evidence, discuss practice patterns, and reach a consensus on the treatment of extensive-stage SCLC (ES-SCLC). The literature search included guidelines, systematic reviews, and randomized controlled trials. Regular meetings were held from September 2022 to March 2023 to discuss the available evidence to propose and agree upon specific recommendations. The panel addressed biomarkers and histological features that distinguish SCLC from non-SCLC and other neuroendocrine tumours. Evidence for initial and subsequent systemic therapies was reviewed with consideration for patient performance status, comorbidities, and the involvement and function of other organs. The resulting consensus recommendations herein will help clarify evidence-based management of ES-SCLC in routine practice, help clinician decision-making, and facilitate the best patient outcomes.

INTRODUCTION: Dyspnea is common in lung cancer and may be partially attributable to increased ventilatory drive due to muscle weakness. The sympathetic component of this pathway might be mitigated by ß-blockers. METHODS: A retrospective review of new patients with stage III-IV non-small lung cancer or any small cell lung cancer was undertaken to assess the impact of ß-blocker use on dyspnea and fatigue. Data were abstracted for clinical characteristics, ß-blocker use, and pre-treatment Edmonton Symptom Assessment System dyspnea and fatigue scores. RESULTS: Of 348 patients assessed, 202 met eligibility criteria. The median age was 67, 55.4% were female, 18.8% had chronic obstructive pulmonary disease (COPD), and 5.9% had active coronary artery disease. Over 60% of patients scored 4/10 or higher on their dyspnea and fatigue scores. While dyspnea and fatigue were moderately associated, no association was found between ß-blocker use and either symptom. Recorded dosages of ß-blockers were low. COPD was associated with dyspnea and fatigue, while anemia was associated with fatigue. CONCLUSIONS: Dyspnea and fatigue are prevalent and increased in the presence of COPD and anemia. No association between ß-blocker use and dyspnea or fatigue scores was observed. This may be attributable to inadequate dosing or to retrospective bias.

Patients with lung cancer have numerous and varying needs spanning across the cancer trajectory; however, only limited research has focused specifically on the pre-diagnosis phase. A multicentre cross-sectional survey was conducted to explore the experience of lung cancer patients during the pre-diagnosis phase. High levels of anxiety were reported by many participants (45.6 %). Informational (32.1 %), and emotional (24.1 %) needs were reported as most important; the majority (89.0 %) reported these needs were met. Most participants sought information throughout, with many (38.6 %) rating their oncology health care providers to be the best source of information. The majority (70.0 %) reported that they were not directed to any resources to help address their anxiety. During pre-diagnosis, informational and emotional needs appear most important, and for the majority, these were reportedly met. Although many experienced high levels of anxiety, few were directed to resources to address it.

Small cell lung cancer (SCLC) is an aggressive neuroendocrine carcinoma with early metastatic potential. The standard-of-care treatment has not changed in years. Recent studies report improved progression-free survival (PFS) and overall survival (OS) with combined ICI and chemotherapy in ES-SCLC. We conducted a systematic review and meta-analysis to assess the magnitude of survival benefits. We searched MEDLINE, EMBASE, and Cochrane between 1 January 2010 and 15 July 2022 and conference proceedings from 2018 to 2022, for randomised controlled trials, evaluating chemo-ICI compared with platinum-doublet chemotherapy in untreated ES-SCLC. Outcomes assessed were PFS, OS, objective response rate (ORR), duration of response (DoR), toxicity, and health-related quality of life (HRQoL). The search identified 8061 studies, with 8 (56 publications) included in the final analysis. PFS and OS were significantly improved for patients randomised to chemo-ICI (PFS hazard ratio (HR) 0.75, 95% confidence interval (CI) 0.70-0.80) and (OS HR 0.79, 95% CI 0.73-0.85). Subgroup analysis demonstrated a differential effect between PD-1/PD-L1 and CTLA-4 inhibitors. There was no difference in ORR and DoR. All-grade adverse events (RR 1.06, 95% CI 1.00-1.12) were similar. The addition of ICI to chemotherapy in untreated ES-SCLC results in a 22% risk reduction in death, and a 25% risk reduction in disease progression with a minimal increase in toxicity. These improvements are modest but represent progress beyond the standard of care.

INTRODUCTION: The aim of this guideline was to provide recommendations for the most effective therapy for patients with thymic epithelial tumors, including thymoma, thymic carcinoma, and thymic neuroendocrine tumors (NETs). This guideline is intended to be used by all health care professionals managing patients with thymic epithelial tumors. METHODS: The guideline was developed by Ontario Health (Cancer Care Ontario)'s Program in Evidence-Based Care and by the Lung Cancer Disease Site Group through a systematic review of the evidence, expert consensus, and formal internal and external reviews. RESULTS: Evidence-based recommendations were developed to improve the management of patients with thymic epithelial tumors. The guideline includes recommendations for surgical, radiation, and systemic treatments for patients with thymoma, thymic carcinoma, and thymic NETs separated by stage of disease using the TNM staging system. Recommendations for patients with thymic NETs were endorsed from the 2021 National Comprehensive Cancer Network Neuroendocrine and Adrenal Tumors Guideline. CONCLUSIONS: This guideline reflects the new staging system for patients with thymoma and thymic carcinoma and includes supporting evidence from the best available studies.

PURPOSE: To provide evidence-based recommendations updating the 2021 ASCO and Ontario Health (Cancer Care Ontario) guideline on systemic therapy for patients with stage IV non-small-cell lung cancer (NSCLC) with driver alterations. METHODS: ASCO updated recommendations on the basis of an ongoing systematic review of randomized control trials from 2020 to 2021. RESULTS: This guideline update reflects changes in evidence since the previous update. Two studies provide the evidence base. Outcomes of interest include efficacy and safety. RECOMMENDATIONS: For patients with an anaplastic lymphoma kinase rearrangement, a performance status (PS) of 0-2, and previously untreated NSCLC, clinicians should offer alectinib or brigatinib or lorlatinib. For patients with an anaplastic lymphoma kinase rearrangement, a PS of 0-2, and previously untreated NSCLC, if alectinib, brigatinib, or lorlatinib are not available, clinicians should offer ceritinib or crizotinib. For patients with a RET rearrangement, a PS of 0-2, and previously untreated NSCLC, clinicians may offer selpercatinib or pralsetinib. In second line, for patients with a RET rearrangement who have not received RET-targeted therapy, clinicians may offer selpercatinib or pralsetinib.Additional information is available at www.asco.org/thoracic-cancer-guidelines.

PURPOSE: To provide evidence-based recommendations updating the 2020 ASCO and Ontario Health (Cancer Care Ontario) guideline on systemic therapy for patients with stage IV non-small-cell lung cancer without driver alterations. METHODS: ASCO updated recommendations on the basis of an ongoing systematic review of randomized clinical trials from 2018 to 2021. RESULTS: This guideline update reflects changes in evidence since the previous update. Five randomized clinical trials provide the evidence base. Outcomes of interest include efficacy and safety. RECOMMENDATIONS: In addition to 2020 options for patients with high programmed death ligand-1 (PD-L1) expression (tumor proportion score [TPS] ≥ 50%), nonsquamous cell carcinoma (non-SCC), and performance status (PS) 0-1, clinicians may offer single-agent atezolizumab. With high PD-L1 expression (TPS ≥ 50%), non-SCC, and PS 0-1, clinicians may offer nivolumab and ipilumumab alone or nivolumab and ipilimumab plus chemotherapy. With negative (0%) and low positive PD-L1 expression (TPS 1%-49%), non-SCC, and PS 0-1, clinicians may offer nivolumab and ipilimumab alone or nivolumab and ipilimumab plus chemotherapy. With high PD-L1 expression, SCC, and PS 0-1, clinicians may offer single-agent atezolizumab. With high PD-L1 expression, squamous cell carcinoma (SCC), and PS 0-1, clinicians may offer nivolumab and ipilimumab alone or in combination with two cycles of platinum-based chemotherapy. With negative and low positive PD-L1 expression, SCC, and PS 0-1, clinicians may offer nivolumab and ipilimumab alone or in combination with two cycles of platinum-based chemotherapy. With non-SCC who received an immune checkpoint inhibitor and chemotherapy as first-line therapy, clinicians may offer second-line paclitaxel plus bevacizumab. With non-SCC, who received chemotherapy with or without bevacizumab and immune checkpoint inhibitor therapy, clinicians should offer the options of third-line single-agent pemetrexed, docetaxel, or paclitaxel plus bevacizumab.Additional information is available at www.asco.org/thoracic-cancer-guidelines.

INTRODUCTION: Treatment algorithms for small cell lung cancer (SCLC) are determined largely by the Veterans Affairs Lung Cancer Staging Group (VALCSG) staging (limited (LS) versus extensive (ES) stage). Relapse occurs frequently; however, patterns of relapse, in particular the competing risk of thoracic and central nervous system relapse, are not well described. This study describes patterns of relapse in SCLC patients treated at a large tertiary institution in Ontario, Canada. MATERIALS AND METHODS: A retrospective cohort of SCLC patients treated at the Juravinski Cancer Centre was reviewed. Data were abstracted from the medical record on demographic, disease, treatment and outcome variables. The primary outcome was a description of the patterns of relapse stratified by disease stage. Multivariate analysis was performed to identify prognostic variables for thoracic and CNS relapse. RESULTS: Two hundred and twenty nine patients were treated during the study period (LS-83, ES-146). Relapse occurred in the majority of patients (isolated thoracic-28%, isolated CNS-9%, extrathoracic-9%, thoracic/extrathoracic-14%, systemic and CNS-13%). The median OS was consistent with published data (LS-21.8 months, ES-8.9 months). ES disease and elevated LDH were prognostic for increased thoracic relapse, whereas poor PS and older age were prognostic for lower central nervous system (CNS) relapse. DISCUSSION: Thoracic relapse and CNS relapse represent competing risks for patients with SCLC. Decisions about incorporating thoracic or CNS radiation are complex. More research is needed to incorporate performance status and LDH into treatment algorithms.
