Radio Chemotherapy

Objectives: In our previous prospective trial on accelerated hypofractionated concomitant radiochemotherapy (AHRT-CHT) for non-small-cell lung cancer (NSCLC) the incidence of grade ≥3 acute esophageal toxicity (AET) was similar to that reported for conventionally fractionated concomitant radiochemotherapy (CFRT-CHT), but its duration was prolonged. Thus, we aimed to compare the duration of grade ≥3 AET between AHRT-CHT and CFRT-CHT. Methods: Clinical data of 76 NSCLC patients treated with CFRT-CHT (60–66 Gy/2 Gy) during 2015–2020 were retrospectively compared with the data of 92 patients treated with AHRT-CHT (58.8 Gy/2.8 Gy) in the prospective trial. The maximum grade of AET, incidence, and duration of grade ≥3 AET were the endpoints. Univariate and multivariate analyses were applied to correlate clinical and treatment variables with these endpoints. Results: Neither the maximum grade of AET (p = 0.71), nor the incidence of grade ≥3 AET (p = 0.87) differed between the two groups. The number of CHT cycles delivered (2 vs 1, p = 0.005) and higher esophagus mean BED (p = 0.009) were significant predictors for a higher maximum grade of AET; older age was a significant predictor for higher incidence of grade ≥3 AET (p = 0.03). The median duration of grade≥3 AET in AHRT-CHT and CFRT-CHT group was 30 days (range 5-150) vs 7 days (range 3-20), respectively, p = 0.0005. In multivariate analysis, only the AHRT-CHT schedule (p=0.003) was a significant predictor for a longer duration of grade≥3 AET. Conclusions Despite similar incidence of grade≥3 AET, its duration is significantly prolonged in NSCLC patients treated with AHRT-CHT compared to CFRT-CHT. Advances in knowledge Reporting only the rate of grade≥3 AET in clinical trials may underestimate the real extent of the esophageal toxicity; its duration should also be routinely reported.

Abstract Background: Single agent maintenance therapy has been approved for the treatment of advanced non-small-cell lung cancer (NSCLC) due to its potential survival benefits, but whether combined maintenance therapy would improve the survival of advanced NSCLC remains undetermined. Methods: Relevant trials were identified by searching electronic databases and conference meetings. Prospective randomized controlled trials (RCTs) assessing combination maintenance therapy in advanced NSCLC patients were included. Outcomes of interest included overall survival (OS), progression-free survival (PFS), and grade 3–4 toxicities. Results: A total of 1950 advanced NSCLC patients received combination maintenance treatment from six trials were included for analysis. The use of doublet maintenance therapy in NSCLC patients significantly improved PFS (HR 0.74, 95%CI: 0.59–0.93, P = 0.010), but not for OS (HR 0.95, 95%CI: 0.85–1.07, P = 0.40) in comparison with single agent maintenance therapy. Similar results were observed in sub-group analysis according to treatment regimens. In addition, there was no significantly risk difference between doublet and single agent maintenance therapy in terms of grade 3/4 hematologic and non-hematologic toxicities. Conclusion: The findings of the present study show that doublet combination maintenance therapy is superior to single agent maintenance therapy in terms of PFS, without increased grade 3–4 toxicities. Future prospective studies are recommended to clearly assess the long-term clinical benefit of doublet maintenance therapy and its impact on health-related quality of life.

Purpose: To compare the survival benefit obtained with cisplatin plus gemcitabine, a cisplatin-based triplet, and nonplatinum sequential doublets in advanced non–small-cell lung cancer (NSCLC). Patients and Methods: Stage IIIB to IV NSCLC patients were randomly assigned to receive cisplatin 100 mg/m2 day 1 plus gemcitabine 1,250 mg/m2 days 1 and 8, every 3 weeks for six cycles (CG); cisplatin 100 mg/m2 day 1 plus gemcitabine 1,000 mg/m2 and vinorelbine 25 mg/m2 days 1 and 8, every 3 weeks for six cycles (CGV); or gemcitabine 1,000 mg/m2 plus vinorelbine 30 mg/m2 days 1 and 8, every 3 weeks for three cycles, followed by vinorelbine 30 mg/m2 days 1 and 8 plus ifosfamide 3 g/m2 day 1, every 3 weeks for three cycles (GV–VI). Results: Five hundred fifty-seven patients were assigned to treatment (182 CG, 188 CGV, 187 GV–VI). Response rates were significantly inferior for the nonplatinum sequential doublet (CG, 42%; CGV, 41%; GV–VI, 27%; CG v GV–VI, P = .003). No differences in median survival or time to progression were observed. Toxicity was higher for the triplet: grade 3 to 4 neutropenia (GC, 32%; CGV, 57%; GV–VI, 27%; P < .05); neutropenic fever (CG, 4%; CGV, 19%; GV–VI, 5%; P < .0001); grade 3 to 4 thrombocytopenia (CG, 19%; CGV, 23%; GV–VI, 3%; P = .0001); and grade 3 to 4 emesis (GC, 22%; GCV, 32%; GV–VI, 6%; P < .0001). Conclusion: On the basis of these results, CG remains a standard regimen for first-line treatment of advanced NSCLC.

The Impact

Background: Stereotactic body radiotherapy (SBRT) in ultra-central (UC) lung tumors, defined in the presence of planning target volume (PTV) overlap or direct tumor abutment to the central bronchial tree or esophagus, may be correlated to a higher incidence of severe adverse events. Outcome and toxicity in oligometastatic (≤3 metastases) non-small-cell lung cancer (NSCLC) patients receiving SBRT for UC tumors were evaluated. Methods: Oligometastatic NSCLC patients treated with SBRT for UC were retrospectively reviewed. Local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS) and overall survival (OS) were calculated. Incidence and grade of toxicity were evaluated. Statistical analysis was performed to assess the impact of clinical and treatment-related variables on outcome and toxicity occurrence. Results: Seventy-two patients were treated to a median biologically effective dose (BED) of 105 (75–132) Gy10. Two-year LC, DMFS, PFS, and OS were 83%, 46%, 43%, and 49%. BED>75 Gy10 was correlated to superior LC (p = 0.02), PFS (p = 0.036), and OS (p < 0.001). Grade ≥3 toxicity rate was 7%, including one fatal esophagitis. No variables were correlated to DMFS or to occurrence of overall and grade ≥3 toxicity. Conclusions: SBRT using dose-intensive schedules improves outcome in NSCLC patients. Overall toxicity is acceptable, although rare but potentially fatal toxicities may occur.

Background. sequential chemotherapy can maintain dose intensity and preclude cumulative toxicity by increasing drug diversity.Purpose. to investigate the toxicity and efficacy of the sequential regimen of gemcitabine followed by paclitaxel in first line advanced stage non-small cell lung cancer (NSCLC) patients with good performance status (PS).Patients and methods. gemcitabine 1250 mg/ was administered on day 1 and 8 of course 1 and 2; Paclitaxel 150 mg/ on day 1 and 8 of course 3 and 4. Primary endpoint was response rate (RR), secondary endpoints toxicity and time to progression (TTP).Results. Of the 21 patients (median age 56, range 38–80 years; 62% males, 38% females) 10% (2/21) had stage IIIB, 90% (19/21) stage IV, 15% PS 0, 85% PS 1. 20% of patients had a partial response, 30% stable disease, 50% progressive disease. Median TTP was 12 weeks (range 6–52 weeks), median overall survival (OS) 8 months (range 1–27 months), 1-year survival was 33%. One patient had grade 3 hematological toxicity, 2 patients a grade 3 peripheral neuropathy.Conclusions. sequential administration of gemcitabine followed by paclitaxel in first line treatment of advanced NSCLC had a favourable toxicity profile, a median TTP and OS comparable with other sequential trials and might , therefore, be a treatment option for NSCLC patients with high ERCC1 expression.

Pembrolizumab has been approved as first-line treatment for advanced Non-small cell lung cancer (NSCLC) patients with tumors expressing PD-L1 and in the absence of other targetable alterations. However, not all patients that meet these criteria have a durable benefit. In this monocentric study, we aimed at refining the selection of patients based on the expression of immune genes. Forty-six consecutive advanced NSCLC patients treated with pembrolizumab in first-line setting were enrolled. The expression levels of 770 genes involved in the regulation of the immune system was analysed by the nanoString system. PD-L1 expression was evaluated by immunohistochemistry. Patients with durable clinical benefit had a greater infiltration of cytotoxic cells, exhausted CD8, B-cells, CD45, T-cells, CD8 T-cells and NK cells. Immune cell scores such as CD8 T-cell and NK cell were good predictors of durable response with an AUC of 0.82. Among the immune cell markers, XCL1/2 showed the better performance in predicting durable benefit to pembrolizumab, with an AUC of 0.85. Additionally, CD8A, CD8B and EOMES showed a high specificity (>0.86) in identifying patients with a good response to treatment. In the same series, PD-L1 expression levels had an AUC of 0.61. The characterization of tumor microenvironment, even with the use of single markers, can improve patients’ selection for pembrolizumab treatment.

Immune checkpoint inhibitors (ICIs) targeting the programmed cell death (PD)-1 protein and its ligand, PD-L1, and cytotoxic T-lymphocyte-associated antigen (CTLA)-4, have revolutionized the management of patients with advanced non-small cell lung cancer (NSCLC). Unfortunately, only a small portion of NSCLC patients respond to these agents. Furthermore, although immunotherapy is usually well tolerated, some patients experience severe immune-related adverse events (irAEs). Liquid biopsy is a non-invasive diagnostic procedure involving the isolation of circulating biomarkers, such as circulating tumor cells (CTC), cell-free DNA (cfDNA), and microRNAs (miRNAs). Thanks to recent advances in technologies, such as next-generation sequencing (NGS) and digital polymerase chain reaction (dPCR), liquid biopsy has become a useful tool to provide baseline information on the tumor, and to monitor response to treatments. This review highlights the potential role of liquid biomarkers in the selection of NSCLC patients who could respond to immunotherapy, and in the identification of patients who are most likely to experience irAEs, in order to guide improvements in care.
