Radiotherapy to reinvigorate immunotherapy activity after acquired resistance in metastatic non-small-cell lung cancer: A pooled analysis of two institutions prospective phase II single arm trials.

[PMID: 38070686 DOI: 10.1016/j.radonc.2023.110048] [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: 09/07/2023] [Revised: 12/01/2023] [Accepted: 12/04/2023] [Indexed: 02/20/2024]
Abstract
AIM The current work aimed to investigate the clinical benefit of radiotherapy in patients with metastatic non-small cell lung cancer (NSCLC) developing acquired resistance to immune checkpoint inhibitors. METHOD We report on a pooled, two-institution, phase II single-arm prospective cohort study. The study included patients with stage IV NSCLC who showed progression of one or more measurable lesions under anti-PD-(L)1 inhibition alone, after initially having achieved at least stable disease. Hypofractionated radiotherapy (hRT) of one to four metastases was performed, while one or more lesions were kept untreated. Following hRT, treatment with immune checkpoint inhibitors was continued unchanged until further evidence of tumor progression or unacceptable toxicity. Primary endpoint of the pooled analysis was progression-free survival (PFS), secondary endpoints included overall survival (OS) and toxicity. RESULTS A total of 48 patients were enrolled: mean age was 67.1 ± 9.3 years, 50 % were male and 72.9 % were PD-L1 positive. Immunotherapy was in 95.8 % of patients the first or second line therapy at time of enrollment. hRT was performed to one (93.8 % of cases) or more lesions (median total dose: 27.5 Gy, median 6.5 Gy/fraction). Forty-five patients (93.8 %) were able to continue immunotherapy for a median of 6.2 months following hRT. Median PFS was 4.4 months, with 62.5 % disease control at three months and 37.5 % at six months. Median OS was 14.9 months. Severe adverse events (grade ≥ 2) were reported in 12 cases (25 %), of which none were radiotherapy-related and four were immunotherapy-related. Salvage therapy consisted of chemotherapy (48.8 %) or repeated irradiation (21.9 %). No further tumor treatment was performed in 29.3 % of patients. CONCLUSIONS The current pooled analysis is a prospective evaluation of the role of radiation therapy for metastatic NSCLC in the setting of newly acquired immunotherapy resistance. Hypofractionated radiotherapy can support the outcome of immune checkpoint inhibitors and thus allow continuation of treatment for a relevant amount of time despite initial tumor progression.

Efficacy of immunotherapy beyond RECIST progression in advanced melanoma: a real-world evidence. Cancer Immunol Immunother 2022; 71:1949-1958.

Abstract
Immunotherapy (ITH) holds the possibility of tumor burden decrease after initial RECIST 1.1 defined progression. The clinical concept of treating selected patients (pts) beyond disease progression (PD) is supported by so-called pseudoprogression phenomenon. The aim of this study was to evaluate real-life practice and outcomes related to treatment beyond (RECIST) progression (TBP) in advanced melanoma patients. Of 584 subsequent melanoma pts analyzed 77 (13.2%) received TBP. In this cohort, the median time to first PD (TTFP) was 5.29 months (m), while time to second PD (TTSP)-8.02 m. On TBP 23.4% pts achieved an objective response (OR), and next 42.9%-stabilization of the disease (SD). 1st PD was reported most often as the development of a new lesion or increase (> 20%) of the diameter of three or more targets. In about 50% second PD was observed as an increase in the diameter of different targets that in 1st PD. Multimodal treatment resulted in 9.82 m TTSP, while ITH alone-4.93 m (p = 0.128). An oligoprogressive pattern of first PD was associated with longer TTSP (HR 0.55, 95% CI: 0.32-0.94). Median OS after first PD was 28.75 months and correlated with OR during TBP (HR 0.18, 95% CI: 0.004-0.76). Selected clinically fit melanoma patients, despite evidence of first radiographic progression, may benefit from continued treatment with PD-1 checkpoint inhibitors, but the findings should be validated in larger prospective trials. Multidisciplinary treatment should be offered to advanced melanoma patients, including radiosurgery or stereotactic radiotherapy of single loci progressing during immunotherapy.
