Organ dysfunction in advanced melanoma patients treated with immune checkpoint inhibitors.

ABSTRACT: BACKGROUND:Real-world data enables evaluation of immune checkpoint inhibitor (ICI) use in advanced melanoma management. We examined characteristics and outcomes of ICI-treated patients with advanced melanoma and organ dysfunction (baseline and emergent). PATIENTS AND METHODS:This retrospective observational study used electronic health records derived from a nationwide dataset to examine advanced melanoma patients treated with first-line ICIs (2011-2018). Clinical characteristics, real-world time to treatment discontinuation (rwTTD), and overall survival (OS) were analyzed for patients with normal organ function and those with organ dysfunction prior to ICI initiation. Patients with emergent dysfunction in the 90?days following ICI initiation were identified and potentially associated characteristics were explored. RESULTS:Of 2,407 patients included; 1,884 and 1,717 had evaluable renal and hepatic laboratory values, respectively. Patients with baseline renal dysfunction (2.4%) were older and more frequently male, and less frequently treated with ICI combinations, than patients with normal renal function. Patients with baseline hepatic dysfunction (2.8%) were similar to patients with normal hepatic function regarding demographics and treatments received. Patients with baseline organ dysfunction displayed shorter rwTTD and OS. Among patients with normal baseline organ function, 4.6% and 7.4% developed renal and hepatic dysfunction within 90?days of ICI initiation, respectively; this was associated with combination ICI treatment. CONCLUSION:Patients with advanced melanoma and baseline organ dysfunction frequently receive ICI treatment but have poorer clinical outcomes than patients with normal organ function. Among patients with normal renal and hepatic function at ICI initiation, emergent organ dysfunction rates in this real-world cohort are similar to those reported in clinical trials. IMPLICATIONS FOR PRACTICE:Real-world data provide an opportunity to understand treatment patterns, toxicity and clinical outcomes among patients treated outside of clinical trials. This study confirms that patients with advanced melanoma and baseline renal or hepatic dysfunction are being treated with ICI therapy, more frequently as monotherapy than in combination therapy. For those real-world patients with normal baseline organ function, emergent renal and hepatic dysfunction are both more common in patients treated with combination versus ICI monotherapy.

Project description:BackgroundResponse to immune checkpoint inhibitors (ICIs) is affected by multiple factors. This study aimed to explore whether sites of metastasis are associated with clinical outcomes of ICIs in advanced non-small-cell lung cancer (NSCLC) patients.MethodsThe data of NSCLC patients with high programmed death-ligand 1 expression and good performance status receiving first-line ICIs monotherapy from Guangdong Provincial People's Hospital between May 2019 and July 2020 were retrospectively analyzed. Metastatic sites included liver, bone, brain, adrenal gland, pleura, and contralateral lung. Progression-free survival (PFS) and overall survival (OS) were compared between different metastatic sites and metastatic burden by the Kaplan-Meier method. Organ-specific disease control rate (OSDCR) of different individual metastatic sites was evaluated.ResultsForty NSCLC patients meeting the criteria were identified. The presence of liver metastasis was significantly associated with shorter PFS (3.1 vs . 15.5 months, P = 0.0005) and OS (11.1 months vs . not reached, P = 0.0016). Besides, patients with bone metastasis tend to get shorter PFS (4.2 vs . 15.5 months, P = 0.0532) rather than OS ( P = 0.6086). Moreover, the application of local treatment could numerically prolong PFS in patients with brain metastasis (15.5 vs . 4.3 months, P = 0.1894). More metastatic organs involved were associated with inferior PFS ( P = 0.0052) but not OS ( P = 0.0791). The presence of liver metastasis or bone metastasis was associated with more metastatic organs (Phi[ϕ]: 0.516, P = 0.001). The highest OSDCR was observed in lung (15/17), and the lowest in the liver (1/4).ConclusionsMetastases in different anatomical locations may be associated with different clinical outcomes and local tumor response to ICIs in NSCLC. ICIs monotherapy shows limited efficacy in patients with liver and bone metastasis, thus patients with this type of metastasis might require more aggressive combination strategies.

Project description:IntroductionAcral melanoma (AM) has different biological characteristics from cutaneous melanoma. Although systemic therapeutic strategies for advanced AM resemble those for advanced cutaneous melanoma, the evidence of the clinical use of immune checkpoint inhibitors (ICIs) for AM is still inadequate. We aimed to systematically analyze the therapeutic effects and safety profile of ICI treatments in advanced AM.MethodsThis systematic review was conducted in line with a previously registered protocol. Three electronic databases, conference abstracts, clinical trial registers, and reference lists of included articles were searched for eligible studies. The primary outcomes were therapeutic effects, and the secondary outcomes were the safety profiles.ResultsThis systematic review included six studies investigating anti-CTLA-4 immunotherapy, 12 studies investigating anti-PD-1 immunotherapy, one study investigating the combination therapy of anti-CTLA-4 and anti-PD-1, and one study investigating anti-PD-1 immunotherapy in combination with radiotherapy. In most studies investigating ipilimumab, the anti-CTLA-4 antibody, the objective response rate ranged from 11.4 to 25%, the median progression-free survival ranged from 2.1 to 6.7 months, and the median overall survival was more than 7.16 months. For studies discussing anti-PD-1 immunotherapy with nivolumab, pembrolizumab, or JS001, the objective response rate ranged from 14 to 42.9%, the median progression-free survival ranged from 3.2 to 9.2 months, and the median overall survival was more than 14 months. The combination therapy of anti-CTLA-4 and anti-PD-1 immunotherapy showed better efficacy with an objective response rate of 42.9% than single-agent therapy. The retrospective study investigating the combination therapy of anti-PD-1 immunotherapy and radiation showed no overall response. Few outcomes regarding safety were reported in the included studies.ConclusionsICIs, especially anti-CTLA-4 monoclonal antibodies combined with anti-PD-1 antibodies, are effective systematic treatments in advanced AM. However, there remains a lack of high-level evidence to verify their efficacy and safety and support their clinical application.
