Immune checkpoint inhibitors (ICI) have been developed in gastric adenocarcinomas and approved in first-line metastatic setting (in combination with chemotherapy) as well as in pretreated patients. Microsatellite instability-high (MSI-H) tumors are predicted to derive high benefit from ICI but data in gastric locations are limited. Here, we describe the case of a 68-year old patient with stage IV MSI-H gastric adenocarcinoma, referred to our center to receive immunotherapy after failure of standard of care (surgery with perioperative platin-based chemotherapy and paclitaxel plus ramucirumab at disease progression). The patient received one injection of durvalumab and tremelimumab and was hospitalized eighteen days after because of occlusive syndrome. The CT scan showed hyperprogression of the lymph nodes and hepatic lesions, compressing the gastric stump. He died few days later. Molecular analyses did not explain this outcome. To our knowledge, this is one of the first reported cases of hyperprogressive disease after combined ICI for a patient with MSI-H tumor. We review the potential causes and discuss the emerging literature regarding predictive factors of hyperprogression in the particular subset of MSI-H patients. If some data were available in retrospective studies, validation of strong predictive factors is needed to avoid such dramatic evolutions.

83 Background: Concurrent chemotherapy (CTX) with checkpoint inhibitors (CPI) has become a new standard of care for treatment naïve stage IV non-small cell lung cancer (NSCLC). Little is known about the timing and pattern of immune-related adverse events (irAEs) when CTX and CPI are combined. We sought to characterize irAEs and determine if combination CTX+CPI affects time to first irAE in comparison to patients (pts) receiving CPI alone. Methods: Advanced NSCLC patients who received at least one dose of a CPI at our institution between 2015 and 2018, either alone or with CTX, were identified. Retrospective review for occurrence of irAEs and clinical outcomes was performed. Proportional hazards models were used to assess time to first irAE for CPI vs CTX+CPI and overall survival (OS) for CPI alone. Results: 149 pts were identified. 112 pts received CPI alone and 37 received CTX+CPI. The proportion of pts with at least 1 irAE was higher in the combination therapy group than the monotherapy group (59% vs 34% of patients). Time to any grade first irAE was shorter with CTX+CPI vs CPI alone (6.0 m vs 36.7 m, HR 1.8, p = 0.0304). Among pts treated with CPI alone, OS was significantly longer with any irAE (38.0 m vs 11.4 m, HR 2.9, p = 0.0026). While there were more irAEs in the CTX+CPI cohort, the frequency of irAEs by organ system was similar to previous reports. Conclusions: For patients receiving CTX+CPI, there is an increased risk of irAEs and a significantly shorter time to first irAE occurrence compared to CPI alone. Among patients receiving CPI alone, the presence of irAE was associated with a 3-fold improvement in OS. Further analysis of OS for the CTX+CPI group is planned with additional follow-up.

4516 Background: Immunotherapy-based combination therapies (IO-X) are standard of care for metastatic RCC (mRCC) in the frontline setting. Limited data is available on the role of cytoreductive nephrectomy prior to IO-X in patients (pts) with mRCC (Bakouny, et al. GU ASCO 2020). We assessed the correlation between nephrectomy prior to IO-X and overall survival (OS) in pts with de novo mRCC. Methods: We pooled data from trials submitted for FDA review of a checkpoint inhibitor combination as first-line treatment for pts with mRCC. We only included trials with available data for stage at initial diagnosis (dx) to identify pts with stage IV disease at initial dx and to exclude those with nephrectomy in the non-metastatic setting. Kaplan-Meier method was used to estimate median OS in pts with de novo mRCC with and without nephrectomy prior to IO-X. Results: Five trials met inclusion criteria, all of which evaluated IO in combination with a kinase inhibitor. Data for stage at initial dx was available in 1708 pts who received IO-X. The majority of pts were male (72%) and White (80%). Among the 849 pts (50%) with stage IV RCC at initial dx, 523 pts (62%) had nephrectomy prior to IO-X. All pts had clear cell histology; Sarcomatoid differentiation was present in tumor pathology of 25% and 10% of pts with and without prior nephrectomy, respectively. Proportion of pts with favorable, intermediate and poor risk disease was 10%, 70% and 20%, respectively. OS appeared better in those with stage IV disease at dx who had prior nephrectomy compared to pts without nephrectomy (Hazard ratio (HR) = 0.53, 95% CI: 0.42, 0.68), even after adjusting for age and prognostic risk group (HR = 0.59, 95% CI: 0.46, 0.75) (see table). Conclusions: In this retrospective exploratory analysis, nephrectomy prior to IO-X in pts with new dx of stage IV RCC appeared to be associated with improved OS, even when controlling for age and prognostic risk group. The decision for nephrectomy is affected by factors such as medical comorbidities which could not be completely controlled. Results should be considered hypothesis generating.[Table: see text]

Following the ATTRACTION-2 study, nivolumab was approved for advanced gastric cancer in Japan. However, pseudoprogression and hyperprogressive disease have been reported in patients treated with immune checkpoint inhibitors. We report a patient with gastric cancer who received nivolumab after radiotherapy only to experience rapid progression within the irradiation field after the first immunotherapy session. A 66-year-old man with dysphagia visited our hospital and was diagnosed with stage IV gastroesophageal cancer (human epidermal growth factor receptor-2 score = 0). He commenced a G-SOX regimen (S-1 80 mg/m2 on days 1–14 and oxaliplatin 100 mg/m2 on day 1, repeated every 3 weeks) in June 2017. The dysphagia worsened despite 3 cycles of G-SOX, and computed tomography (CT) revealed constriction of the gastroesophageal junction. To ameliorate the dysphagia, palliative chemoradiotherapy (S-1 and 50.4 Gy in 28 fractions) was performed starting in August 2017. The patient’s dysphagia had not resolved after completing radiotherapy, and pain on swallowing worsened. Nivolumab (3 mg/m2 every 2 weeks) was administered 7 days after the completion of radiotherapy. The patient experienced malaise and worsening dysphagia before the second cycle. CT 15 days after the first nivolumab administration revealed rapid progression in the irradiation field. His general condition rapidly deteriorated, and he died 24 days after the first administration. This episode suggests that administration of nivolumab after radiotherapy may be a risk factor for hyperprogressive disease.

Treatment algorithms in the treatment of advanced non-small cell lung cancer (NSCLC) continue to evolve as new therapeutics show positive efficacy improvements. This review article summarizes the data for the use of immunotherapy for treatment in first-line stage IV NSCLC, organized by the following four sections: single-agent immunotherapy, immunotherapy and chemotherapy, dual immunotherapy, and dual immunotherapy and chemotherapy. The results are summarized and tabulated. Finally, application of the trial data is illustrated in four clinical scenarios depending on the programmed death-ligand 1 (PD-L1) expression levels. Single checkpoint inhibitors have become an easy and excellent treatment in patients whose tumors have high PD-L1 expression. Adding chemotherapy to immunotherapy benefits our patients. Immunotherapy, with or without chemotherapy, is now the standard of care in the first-line setting in patients without EGFR, ALK, or ROS driver mutations.

In recent years, incredible progress has been made in the treatment of metastatic renal cell carcinoma, with a paradigm shift from the use of cytokines to tyrosine kinase inhibitors, and more recently, immune checkpoint inhibitors (ICIs). Despite advances in the metastatic setting, effective therapies in the adjuvant setting are a largely unmet need. Currently, sunitinib (Sutent, Pfizer) is the only therapy for the adjuvant treatment of RCC included in the National Comprehensive Cancer Network guidelines, which was approved by the FDA based on the improvement in disease-free survival (DFS) seen in the S-TRAC trial. However, improvement in DFS has not translated into an overall survival (OS) benefit for patients at high-risk of relapse post-nephrectomy, illustrating the need for more effective therapies. This manuscript will highlight attributes of both historical and current drug trials and their implications on the landscape of adjuvant therapy. Additionally, we will outline strategies for selecting patients in whom treatment would be most beneficial, as optimal patient selection is a crucial step towards improving outcomes in the adjuvant setting. This is especially critical, given the financial cost and pharmacological toxicity of therapeutic agents. Furthermore, we will review the design of clinical trials including the value of utilizing OS as an endpoint over DFS. Finally, we will discuss how the incorporation of genomic data into predictive models, the use of more sensitive imaging modalities for more accurate staging, and more extensive surgical intervention involving lymph node dissection, may impact outcomes.

Merkel cell carcinoma (MCC) is an often-lethal skin cancer with increasing incidence and limited treatment options. Although immune checkpoint inhibitors (ICI) have become the standard of care in advanced MCC, 50% of all MCC patients are ineligible for ICIs, and amongst those treated, many patients develop resistance. There is no therapeutic alternative for these patients, highlighting the urgent clinical need for alternative therapeutic strategies. Using patient-derived genetic insights and data generated in our lab, we identified aurora kinase as a promising therapeutic target for MCC. In this study, we examined the efficacy of the recently developed and highly selective AURKA inhibitor, AK-01 (LY3295668), in six patient-derived MCC cell lines and two MCC cell-line-derived xenograft mouse models. We found that AK-01 potently suppresses MCC survival through apoptosis and cell cycle arrest, particularly in MCPyV-negative MCC cells without RB expression. Despite the challenge posed by its short in vivo durability upon discontinuation, the swift and substantial tumor suppression with low toxicity makes AK-01 a strong potential candidate for MCC management, particularly in combination with existing regimens.

Colorectal cancer (CRC) is the third most common cancer type in both men and women in the USA. Most patients with CRC are diagnosed as local or regional disease. However, the survival rate for those diagnosed with metastatic disease remains disappointing, despite multiple treatment options. Cancer therapies for patients with unresectable or metastatic CRC are increasingly being driven by particular biomarkers. The development of various immune checkpoint inhibitors has revolutionized cancer therapy over the last decade by harnessing the immune system in the treatment of cancer, and the role of immunotherapy continues to expand and evolve. Pembrolizumab is an anti-programmed cell death protein 1 immune checkpoint inhibitor and has become an essential part of the standard of care in the treatment regimens for multiple cancer types. This paper reviews the increasing evidence supporting and defining the role of pembrolizumab in the treatment of patients with unresectable or metastatic CRC.

Abstract Background Immune checkpoint inhibitors (ICIs) have become the standard of care for a variety of cancers, including non-small cell lung cancer (NSCLC). In this study, we investigated the frequency of pseudoprogression and hyperprogression in lung cancer patients treated with ICIs in the real world and aimed to discover a novel candidate marker to distinguish pseudoprogression from hyperprogression soon after ICI treatment. Methods This study included 74 patients with advanced NSCLC who were treated with PD-1/PD-L1 inhibitors at Chungnam National University Hospital (CNUH) between January 2018 and August 2020. Chest X-rays were examined on day 7 after the first ICI dose to identify changes in the primary mass, and the response was assessed by computed tomography (CT). We evaluated circulating regulatory T (Treg) cells using flow cytometry and correlated the findings with clinical outcomes. Results The incidence of pseudoprogression was 13.5%, and that of hyperprogression was 8.1%. On day 7 after initiation of treatment, the frequency of CD4+CD25+CD127loFoxP3+ Treg cells was significantly decreased compared with baseline (P = 0.038) in patients who experienced pseudoprogression and significantly increased compared with baseline (P = 0.024) in patients who experienced hyperprogression. In the responder group, the frequencies of CD4+CD25+CD127loFoxP3+ Treg cells and PD-1+CD4+CD25+CD127loFoxP3+ Treg cells were significantly decreased 7 days after commencement of treatment compared with baseline (P = 0.034 and P < 0.001, respectively). Conclusion Circulating Treg cells represent a promising potential dynamic biomarker to predict efficacy and differentiate atypical responses, including pseudoprogression and hyperprogression, after immunotherapy in patients with NSCLC.

Opinion statementAdvanced colorectal cancer (CRC) is a heterogeneous disease, characterized by several subtypes with distinctive genetic and epigenetic patterns. During the last years, immune checkpoint inhibitors (ICIs) have revamped the standard of care of several tumors such as non-small cell lung cancer and melanoma, highlighting the role of immune cells in tumor microenvironment (TME) and their impact on cancer progression and treatment efficacy. An “immunoscore,” based on the percentage of two lymphocyte populations both at tumor core and invasive margin, has been shown to improve prediction of treatment outcome when added to UICC-TNM classification. To date, pembrolizumab, an anti-programmed death protein 1 (PD1) inhibitor, has gained approval as first-line therapy for mismatch-repair-deficient (dMMR) and microsatellite instability-high (MSI-H) advanced CRC. On the other hand, no reports of efficacy have been presented in mismatch-repair-proficient (pMMR) and microsatellite instability-low (MSI-L) or microsatellite stable (MSS) CRC. This group includes roughly 95% of all advanced CRC, and standard chemotherapy, in addition to anti-EGFR or anti-angiogenesis drugs, still represents first treatment choice. Hopefully, deeper understanding of CRC immune landscape and of the impact of specific genetic and epigenetic alterations on tumor immunogenicity might lead to the development of new drug combination strategies to overcome ICIs resistance in pMMR CRC, thus paving the way for immunotherapy even in this subgroup.

Abstract Background Studies have shown that immune checkpoint inhibitors (ICIs) have limited efficacy and can even increase tumour burden in short time periods. This is usually called hyperprogressive disease (HPD). To date, there are few reports regarding HPD; fewer have analysed the relationship between HPD and radiotherapy combined with ICIs, and their conclusions are controversial. Case presentation A 42-year-old woman was diagnosed with stage IV renal clear cell carcinoma. The patient had previously received sorafenib and pazopanib as first- and second-line therapies, respectively. She received radiotherapy combined with nivolumab. Eighteen days after administration of the third dose of nivolumab, the patient’s general condition deteriorated; this was associated with immune-related adverse events. Computed tomography showed that the diameter of left lung metastases had sharply increased. A biopsy of the lung metastasis showed no infiltration of lymphocytes. The patient’s general condition worsened and she died of the disease on the 70th day after administration of the third dose of nivolumab. Conclusions This report describes the development of HPD following the administration of radiotherapy combined with ICIs in a case of advanced renal cell carcinoma. The case indicates that radiotherapy may show bidirectional regulation effects on anti-tumour immune response. If the immunosuppressive function of radiotherapy is dominant, combined with ICIs, it could result in HPD.
