Muscle Invasive

Radical cystectomy is the primary treatment for muscle-invasive bladder cancer; however, approximately 50% of patients develop metastatic disease within 2 years of diagnosis, which results in dismal prognosis. Therefore, systemic treatment is important to improve the prognosis of muscle-invasive bladder cancer. Currently, several guidelines recommend cisplatin-based neoadjuvant chemotherapy before radical cystectomy, and adjuvant chemotherapy is recommended in patients who have not received neoadjuvant chemotherapy. Immune checkpoint inhibitors have recently become the standard treatment option for metastatic urothelial carcinoma. Owing to their clinical benefits, several immune checkpoint inhibitors, with or without other agents (including other immunotherapy, cytotoxic chemotherapy, and emerging agents such as antibody drug conjugates), are being extensively investigated in perioperative settings. Several studies for perioperative immunotherapy have shown that immune checkpoint inhibitors have promising efficacy with relatively low toxicity, and have explored the predictive molecular biomarkers. Herein, we review the current evidence and discuss the future perspectives of perioperative systemic treatment for muscle-invasive bladder cancer.

The Impact

e16528 Background: Immune checkpoint inhibitors (ICIs) targeting PD-1/L1 have been approved as first-line treatment for cisplatin-ineligible patients and as second-line therapy for patients with metastatic urothelial carcinoma of the bladder. Biomarkers can help select patients who are more likely to response to ICIs. RNF43 is an E3 ubiquitin ligase that acts as a negative regulator of Wnt/β-catenin signaling pathway. In colorectal cancer (CRC) patients treated with immune checkpoint inhibitors (ICIs), RNF43 mutations predicted longer overall survival (OS). The impact of RNF43 mutations on the efficiency of ICIs in bladder cancer(BLC) remains to be explored. Methods: We downloaded the mutation and clinical data of 211 BLC patients treated with ICIs from the immunotherapeutic cohort published by Samstein et al. (2019). OS analyses were conducted using Kaplan-Meier curves and log-rank tests. Wilcoxon test was used for the comparison of TMB. We also downloaded a TCGA cohort for prognostic analysis. The correlations between RNF43 and immune infiltrates were analyzed in the TIMER2.0 database. Statistical significance was set at p = 0.05. Results: RNF43 mutations were identified in 4.3%(9/211) and 3%(13/438) BLC patients in the immunotherapeutic and TCGA cohort, respectively. In the immunotherapeutic cohort, patients with RNF43 mutations had significantly longer OS (25 months vs 8 months; p = 0.015) and higher tumor mutation burden(TMB, 42.3 vs 7.9; p = 3.15E-06) than RNF43-wild-type patients. Different from this, no significant difference was found in OS between RNF43-mutant and RNF43-wild-type BLC patients with standard treatment in the TCGA cohort (p = 0.696). These results indicated that RNF43 was not a prognostic factor but a predictive biomarker of survival in BLC treated with ICIs. No difference was observed in subsets of immune cells between RNF43-mutant and the RNF43-wide-type BLC patients, including neutrophils, macrophages, CD8+ T cells, Tregs, B cells and NK cells. Conclusions: RNF43 mutations may be a predictor of survival benefit from ICIs in bladder cancer and correlated with higher TMB. Further studies in other ICI-treated cohorts are needed to confirm these results.

Muscle Invasive

Bladder cancer is the seventh most frequent cancer worldwide. The majority of patients present with nonmuscle invasive disease, while 20% of the patients are diagnosed with muscle-invasive bladder cancer. The treatment of nonmuscle invasive disease is endoscopic resection followed by intravesical adjuvant treatment for high risk patients. The standard treatment of localized muscle-invasive disease is neoadjuvant chemotherapy followed by radical cystectomy. Platinum-based chemotherapy is the first-line treatment in locally advanced or metastatic urothelial carcinoma. Immune checkpoint inhibitors have been approved for the treatment of metastatic urothelial carcinoma as second-line treatment or first-line in platinum-ineligible patients. Recently, pembrolizumab have been approved in BCG-refractory nonmuscle invasive bladder cancer. This review summarizes the current evidence concerning immunotherapy in the treatment of urothelial carcinoma.

Abstract Purpose This article explores the efficacy, toxicity, place in therapy, and considerations for use of recently approved immune checkpoint inhibitors (ICIs) in the treatment of non–small cell lung cancer (NSCLC). Summary Lung cancer is the leading cause of cancer mortality in the United States and is responsible for more cancer-related deaths than breast, prostate, and colorectal cancer combined. The landscape for lung cancer treatment is evolving with the approval of new and exciting novel therapies. Within the last decade numerous ICIs have been approved for use in the management of the most common subtype of lung cancer, NSCLC. The ICI agents currently approved by the Food and Drug Administration (FDA) for use in NSCLC include ipilimumab, pembrolizumab, nivolumab, durvalumab, and atezolizumab. These agents are approved for specific indications; therefore, they are not interchangeable. This review focuses on the landmark trials that led to each FDA-approved indication, as well as common toxicities seen with use of these agents. It also discusses the use of ICIs in special populations and unique considerations prior to initiation of treatment with these novel therapies in a patient with NSCLC. Conclusion ICIs can provide a breakthrough treatment option for the management of NSCLC and are rapidly being adopted into clinical practice. It is important to be familiar with appropriate selection of an ICI therapy option for each patient based on approved indication, unique considerations, and anticipated toxicities.

Muscle Invasive

In urothelial cancer of the bladder, the introduction of immunotherapy with immune checkpoint inhibitors represents progress in the management of the disease’s early and advanced stages. In particular, recent studies have implemented these drugs in the neoadjuvant and adjuvant phases to treat muscle-invasive bladder cancer. In some studies, patients received neoadjuvant immune checkpoint inhibitors alone (PURE and ABACUS) to treat muscle invasive bladder cancer, whereas other studies provided this therapy to cisplatin-ineligible patients. Furthermore, a large Phase III study (CheckMate 247) compared placebo with adjuvant nivolumab therapy in patients with high-risk urothelial cancer after neoadjuvant chemotherapy and surgery or surgery alone. Despite some uncertain niches (nonbladder, PD-L1-negative tumors, and node-negative resected cancers), certain biological opportunities (exploring new targets, evaluating in vivo pathologic response, focusing on biomarkers for response) and clinical uses (avoiding chemotherapy at all or in frail patients, attaining similar pathologic complete response rates as in cisplatin-based chemotherapy) are valid reasons for incorporating these agents into the therapeutic armamentarium of medical uro-oncologists.

The Impact

Manipulation of the immune response is a game changer in lung cancer treatment, revolutionizing management. PD1 and CTLA4 are dynamically expressed on different T cell subsets that can either disrupt or sustain tumor growth. Monoclonal antibodies (MoAbs) against PD1/PDL1 and CTLA4 have shown that inhibitory signals can be impaired, blocking T cell activation and function. MoAbs, used as both single-agents or in combination with standard therapy for the treatment of advanced non-small cell lung cancer (NSCLC), have exhibited advantages in terms of overall survival and response rate; nivolumab, pembrolizumab, atezolizumab and more recently, durvalumab, have already been approved for lung cancer treatment and more compounds are in the pipeline. A better understanding of signaling elicited by these antibodies on T cell subsets, as well as identification of biological determinants of sensitivity, resistance and correlates of efficacy, will help to define the mechanisms of antitumor responses. In addition, the relevance of T regulatory cells (Treg) involved in immune responses in cancer is attracting increasing interest. A major challenge for future research is to understand why a durable response to immune checkpoint inhibitors (ICIs) occurs only in subsets of patients and the mechanisms of resistance after an initial response. This review will explore current understanding and future direction of research on ICI treatment in lung cancer and the impact of tumor immune microenvironment n influencing clinical responses.
