Abstract
BACKGROUND Systemic inflammation is believed to contribute to small cell lung cancer (SCLC) progression, but the underlying relationship remains unclear. Lipocalin-2, a potential biomarker of inflammation, has been implicated in various cancers but its prognostic value in SCLC is underexplored. METHODS We retrospectively analyzed 191 patients with SCLC (72 with limited-stage [LD] and 119 with extensive-stage) treated using platinum-based chemotherapy. Lipocalin-2 expression was evaluated using immunohistochemistry. Optimal cutoff values for lipocalin-2 and neutrophil-to-lymphocyte ratio (NLR) were determined using time-dependent receiver operating characteristic curve analysis. The pectoralis muscle index was used to assess sarcopenia. RESULTS In LD-SCLC, high lipocalin-2 expression was associated with worse progression-free survival (PFS; median: 7.0 vs. 15.9 months, p = 0.015) and overall survival (OS; median: 12.9 vs. 30.3 months, p = 0.035) compared with low lipocalin-2 expression. Patients were stratified into three prognostic groups by combining lipocalin-2 with NLR: low lipocalin-2/low NLR, high lipocalin-2/low NLR or low lipocalin-2/high NLR, and high lipocalin-2/high NLR (median PFS: 17.3 vs. 11.0 vs. 6.3 months, p = 0.004; median OS: 30.5 vs. 17.3 vs. 8.6 months, p = 0.002). Similar trends were observed when combining lipocalin-2 with the pectoralis muscle index. High lipocalin-2 expression was also associated with lower complete response rates (18.9% vs. 34.3%, p = 0.035). No significant prognostic implications were found for lipocalin-2 in extensive-stage SCLC. CONCLUSIONS High lipocalin-2 expression is potentially associated with poorer survival in LD-SCLC. Combining lipocalin-2 with other inflammation-related markers could improve prognostic stratification.

Long-Term Survival and Stable Disease in a Patient with Extensive-Stage Small-Cell Lung Cancer after Treatment with Carboplatin, Etoposide and Atezolizumab. Oncol Ther 2024; 12:175-182. [PMID: 38280181 PMCID: PMC10881916 DOI: 10.1007/s40487-023-00257-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Accepted: 12/07/2023] [Indexed: 01/29/2024] Open
Abstract
Survival beyond 2 years is rare in patients with extensive-stage small-cell lung cancer (ES-SCLC) treated with chemotherapy alone. We describe a patient with ES-SCLC who was treated with carboplatin, etoposide and the programmed death-ligand 1 inhibitor atezolizumab in the IMpower133 study (ClinicalTrials.gov registration: NCT02763579) and who achieved exceptionally long-term survival. Treatment-naïve patients with ES-SCLC (n = 403) were included in the IMpower133 study, and the identified patient had been randomised to the investigational treatment arm, where patients received induction therapy with carboplatin and etoposide plus atezolizumab for four 21-day cycles, followed by ongoing maintenance therapy with atezolizumab. The patient had achieved a partial response after induction therapy, and then received seven cycles of atezolizumab maintenance therapy until immune-related toxicities necessitated discontinuation. The patient was alive with an ongoing response and excellent performance status more than 6 years after starting treatment and 5 years after discontinuing atezolizumab maintenance. In conclusion, this patient with ES-SCLC from the IMpower133 study is a rare example of ongoing survival more than 6 years beyond diagnosis and the start of treatment with first-line atezolizumab. This demonstrates the potential durability of response with immunotherapy.

Atezolizumab addition to platinum doublet: evaluating survival outcomes for patients with extensive disease small cell lung cancer. J Cancer Res Clin Oncol 2023; 149:17419-17426. [PMID: 37878090 DOI: 10.1007/s00432-023-05457-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 10/03/2023] [Indexed: 10/26/2023]
Abstract
BACKGROUND The efficacy of adding atezolizumab to the platinum doublet regimen for extensive disease small cell lung cancer (ED-SCLC) remains marginally limited. METHODS We retrospectively assessed the real-world efficacy and safety of atezolizumab in addition to carboplatin and etoposide (EP + A), versus carboplatin and etoposide (EP) alone in previously untreated ED-SCLC patients. RESULTS From a total of 99 patients, 46 were assigned to the EP + A group, and 53 to the EP group. No significant difference was observed in progression-free survival between the groups. However, the overall survival (OS) was significantly longer in the EP + A group (20.8 vs 12.1 months; HR: 0.52; p = 0.0127). Patients older than 70 years, male, with performance status 0-1, without liver metastasis, and low levels of C-reactive protein and neutrophil-lymphocyte ratio, experienced longer OS in the EP + A group compared to the EP group. CONCLUSION The addition of atezolizumab to the platinum doublet regimen significantly extended OS in ED-SCLC patients, particularly among certain subgroups, suggesting its potential value in personalized treatment strategies. Further investigation is warranted to validate these findings.
