Phase 1 study of pembrolizumab plus chemotherapy in Japanese patients with extensive-stage small-cell lung cancer.

BACKGROUND: Part E of the KEYNOTE-011 (NCT01840579) study assessed the safety and antitumor activity of pembrolizumab plus platinum-etoposide chemotherapy in Japanese patients with previously untreated extensive-stage small-cell lung cancer (ES-SCLC). METHODS: Patients received 4 cycles of pembrolizumab (200 mg) every 3 weeks in combination with cisplatin (75 mg/m2) and etoposide (100 mg/m2; days 1, 2, 3) in cohort 1; with carboplatin (AUC 5 mg/mL/min) and etoposide (100 mg/m2; days 1, 2, 3) in cohort 2; or with cisplatin/etoposide and pegfilgrastim (3.6 mg; cycle 1, day 4) in cohort 3. Combination therapy was followed by pembrolizumab monotherapy (31 cycles). The primary endpoint was safety and tolerability (including dose-limiting toxicities; DLTs). RESULTS: Fifteen patients were included in the study (cohort 1, n = 6; cohort 2, n = 6; cohort 3, n = 3). Median time from treatment allocation to data cutoff was 22.1 months (range, 4.1‒32.4 months). DLTs occurred in 3 patients in cohort 1 (one patient with grade 4 laryngeal stenosis and grade 3 febrile neutropenia; two patients with grade 3 febrile neutropenia); no patients in cohorts 2 or 3 experienced DLTs. Grade ≥ 3 treatment-related adverse events included leukopenia (67%) and neutropenia (87%). Among all patients, ORR was 67% (95% CI, 38%‒88%) and median DOR was 4.5 months (range, 2.8‒28.8 months). Median PFS was 4.2 months (95% CI, 3.0‒7.8 months) and median OS was 22.1 months (95% CI, 7.4‒25.9 months). CONCLUSION: Pembrolizumab in combination with platinum-etoposide therapy had manageable toxicity with no new safety signals and was associated with antitumor activity in Japanese patients with ES-SCLC.

Gemcitabine-based conditioning compared to BEAM/BEAC conditioning prior to autologous stem cell transplantation for non-Hodgkin lymphoma: No difference in outcomes.

BACKGROUND: High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) remains an effective treatment for non-Hodgkin lymphoma (NHL). The limited availability of carmustine has prompted the exploration of novel alternative conditioning regimens. This study aimed to compare the efficacy and safety profile of GBM/GBC (gemcitabine, busulfan, and melphalan or cyclophosphamide) conditioning compared with the standard BEAM/BEAC regimens (carmustine, etoposide, cytarabine, and melphalan or cyclophosphamide) for ASCT in patients with NHL. METHODS: A retrospective analysis was conducted on 231 NHL patients, who underwent ASCT from October 2010 to October 2021 at the Institute of Hematology & Blood Disease Hospital, including both first-line and salvage settings. This resulted in the inclusion of 112 patients in the GBM/GBC arm and 92 in the BEAM/BEAC arm. Propensity score matching was employed to validate the results. RESULTS: Disease subtype distribution was similar between the GBM/GBC and BEAM/BEAC groups, with diffuse large B-cell lymphoma being the most common (58.9% vs. 58.7%), followed by PTCL (17.0% vs. 18.5%) and MCL (14.3% vs. 14.1%). At 3 months post-ASCT, complete response (CR) rates were comparable (GBM/GBC 93.5% vs. BEAM/BEAC 91.1%; p = 0.607). The 4-year progression-free survival (78.4% vs. 82.3%; p = 0.455) and 4-year overall survival (88.1% vs. 87.7%; p = 0.575) were also similar. Both groups exhibited low non-relapse mortality at 4 years (GBM/GBC 1.8% vs. BEAM/BEAC 3.5%; p = 0.790) with no transplant-related mortalities reported. The GBM/GBC cohort demonstrated a higher incidence of grade 3/4 oral mucositis and hepatic toxicity, whereas the BEAM/BEAC group had more frequent cases of bacteremia or sepsis (13 cases vs. 5 in GBM/GBC). CONCLUSIONS: The GBM/GBC regimen is effective and well-tolerated, offering outcomes that are highly comparable to those in NHL patients conditioned with BEAM/BEAC, as demonstrated in a prognostically matched cohort.

CEAC (oral semustine, etoposide, cytarabine and cyclophosphamide) vs BEAM (carmustine, etoposide, cytarabine, and melphalan) conditioning regimen of autologous stem cell transplantation for diffuse large B-cell lymphoma: a post-hoc, propensity score-matched, cohort study in Chinese patients.

Autologous stem cell transplantation (ASCT) is a salvage therapy for relapsed or refractory diffuse large B-cell lymphoma (DLBCL). We have developed a novel conditioning regimen called CEAC (oral semustine 250 mg/m2 d-6, etoposide 300 mg/m2 d-5 ~ d-2, cytarabine 500 mg/m2 d-5 ~ d-2, and cyclophosphamide 1200 mg/m2 d-5 ~ d-2) In lymphoma patients in China. Here, we conducted a study to compare the conventional BEAM regimen with the CEAC regimen in 110 DLBCL patients. Propensity-score matching was performed in a 1:4 ratio (22 patients received BEAM and 88 received CEAC). Our results showed no significant difference in the overall response rate (95% vs 97%, P = 1.000) and complete response rate (66% vs 73%, P = 0.580) between the two cohorts. The 5-year progression-free survival (PFS), 5-year overall survival (OS), and 5-year cumulative incidence of relapse (CIR) for all patients were 72% (95% CI 62%-82%), 92% (95% CI 86%-97%), and 29% (95% CI 17%-38%), respectively. There was no significant difference in the 5-year PFS (80% vs 70%, P = 0.637), 5-year OS (95% vs 91%, P = 0.496), and 5-year CIR (20% vs 30%, P = 0.733) between cohorts. In terms of safety, the CEAC cohort had a lower incidence rate of grade 1-2 gastrointestinal hemorrhage (P = 0.023) and severe nausea (P = 0.007) compared with the BEAM cohort. In conclusion, the CEAC regimen seems to be a suitable alternative to the BEAM regimen for ASCT in DLBCL patients.

Acute infusion-related reactions in pediatric patients receiving etoposide at a tertiary cancer center.

INTRODUCTION: Etoposide is a key component of many pediatric chemotherapy regimens for both hematologic and solid tumors. It is well documented that patients receiving etoposide may experience infusion-related reactions. METHODS: In this study, total doses of etoposide and etoposide phosphate were identified, and infusion-related reactions were retrospectively evaluated at a large pediatric oncology ambulatory clinic. The primary outcome was to determine the rate of acute infusion-related reactions to etoposide. A secondary objective was to identify potential risk factors associated with such reactions. RESULTS: Overall, 1463 doses of etoposide were dispensed to 150 unique patients and 15 patients (10%) experienced etoposide infusion-related reactions. Of the 15 patients that experienced etoposide infusion-related reaction, two were successfully able to tolerate subsequent infusions with a slower etoposide infusion rate and pre-medications. The remaining patients changed drug formulation to etoposide phosphate (n = 12) or continued therapy without any formulation of etoposide (n = 1). Patients with classical Hodgkin's lymphoma experienced a higher incidence of infusion-related reactions compared to the overall patient population (30.5% vs. 10%) and made up 73.3% of all infusion-related reactions during the study period. CONCLUSIONS: During the examined study period, 10% of patients experienced an acute infusion-related reaction to etoposide. This review builds on previous literature concluding that additional monitoring may be warranted in patients with classical Hodgkin's lymphoma receiving etoposide.

Therapeutic effectiveness of anlotinib combined with etoposide in extensive-stage small-cell lung cancer: a single-arm, phase II trial.

BACKGROUND: Anlotinib plus chemotherapy as first-line treatment for extensive-stage small-cell lung cancer (ES-SCLC) achieves good efficacy, but there is still room for improvement. This clinical study examined the effectiveness of anlotinib plus etoposide for maintenance therapy in ES-SCLC. METHODS: The current single-arm, prospective phase II study was performed at Jiangsu Cancer Hospital (March 2019 to March 2022). After successful primary etoposide-based therapy, anlotinib was administered at 12 mg/day on days 1 to 14 of 21-day cycles until disease progression or consent withdrawal. All patients also received etoposide at 50 mg/day on days 1 to 14 of 21-day cycles for a maximum of six cycles. Progression-free survival (PFS) constituted the primary study endpoint. Secondary endpoints were overall survival (OS), objective remission rate (ORR), disease control rate (DCR), and safety. In addition, adverse events (AEs) were assessed. RESULTS: Twenty-eight patients were treated. Median PFS and OS were 8.02 (95%CI 5.36-10.67) and 11.04 (95%CI 10.37-11.68) months, respectively. Totally 9 and 18 participants showed a partial response and stable disease, respectively; ORR and DCR were 32.14% and 96.43%, respectively. The commonest all-grade AEs were fatigue (n = 11, 39.28%), hypertension (n = 11, 39.28%), loss of appetite (n = 9, 32.14%), oral mucositis (n = 7, 25.00%) and proteinuria (n = 6, 21.40%). Grade 3-4 AEs included fatigue (n = 4, 14.28%), hypertension (n = 2, 7.14%), hand and foot syndrome (n = 2, 7.14%), oral mucositis (n = 1, 3.57%), hemoptysis (n = 1, 3.57%), proteinuria (n = 1, 3.57%), gingival bleeding (n = 1, 3.57%), and serum creatinine elevation (n = 1, 3.57%). CONCLUSION: Maintenance anlotinib plus etoposide achieves promising PFS and OS in clinical ES-SCLC. REGISTRATION NUMBER: ChiCTR1800019421.

Atezolizumab addition to platinum doublet: evaluating survival outcomes for patients with extensive disease small cell lung cancer.

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.

Utility of routine pulmonary function test after autologous hematopoietic cell transplantation in lymphoma.

This study aims to evaluate the predictive value of routine pulmonary function testing (PFT) at the 12-month mark post-autologous hematopoietic cell transplant (AHCT) in identifying clinically significant lung disease in lymphoma survivors. In 247 patients, 173 (70%) received BEAM (carmustine, etoposide, cytarabine, melphalan), and 49 (20%) received TBC (thiotepa, busulfan, cyclophosphamide) conditioning regimens. Abnormal baseline PFT was noted in 149 patients (60%). Thirty-four patients had a significant decline (reduction of >/= 20% in DLCO or FEV1 or FVC) in post-AHCT PFT, with the highest incidence in the CNS lymphoma group (39%). The incidence of clinically significant lung disease post-transplant was low at 2% and there was no association between abnormal pre- and 1-year post-transplant PFTs with the development of clinical lung disease. While this study illustrates the impact of treatment regimens on PFT changes, it did not demonstrate a predictive value of scheduled PFTs in identifying clinically significant post-AHCT lung disease.

Randomized phase-III study of low-dose cytarabine and etoposide + /- all-trans retinoic acid in older unfit patients with NPM1-mutated acute myeloid leukemia.

The aim of this randomized clinical trial was to evaluate the impact of all-trans retinoic acid (ATRA) in combination with non-intensive chemotherapy in older unfit patients (> 60 years) with newly diagnosed NPM1-mutated acute myeloid leukemia. Patients were randomized (1:1) to low-dose chemotherapy with or without open-label ATRA 45 mg/m2, days 8-28; the dose of ATRA was reduced to 45 mg/m2, days 8-10 and 15 mg/m2, days 11-28 after 75 patients due to toxicity. Up to 6 cycles of cytarabine 20 mg/day s.c., bid, days 1-7 and etoposide 100 mg/day, p.o. or i.v., days 1-3 with (ATRA) or without ATRA (CONTROL) were intended. The primary endpoint was overall survival (OS). Between May 2011 and September 2016, 144 patients (median age, 77 years; range, 64-92 years) were randomized (72, CONTROL; 72, ATRA). Baseline characteristics were balanced between the two study arms. The median number of treatment cycles was 2 in ATRA and 2.5 in CONTROL. OS was significantly shorter in the ATRA compared to the CONTROL arm (p = 0.023; median OS: 5 months versus 9.2 months, 2-years OS rate: 7% versus 10%, respectively). Rates of CR/CRi were not different between treatment arms; infections were more common in ATRA beyond treatment cycle one. The addition of ATRA to low-dose cytarabine plus etoposide in an older, unfit patient population was not beneficial, but rather led to an inferior outcome.The clinical trial is registered at clinicaltrialsregister.eu (EudraCT Number: 2010-023409-37, first posted 14/12/2010).

Benmelstobart Ups ES-SCLC Survival.

The combination of the PD-L1 inhibitor benmelstobart, the angiogenesis inhibitor anlotinib, and the chemotherapies etoposide and carboplatin significantly improved progression-free survival and overall survival compared with the chemotherapies alone in patients with newly diagnosed extensive-stage small cell lung cancer. Both survival measures were longer than those seen with any other trials in this population of patients.

Efficacy of ESHAP versus ICE plus dexamethasone (DICE) as salvage chemotherapy for relapsed or refractory diffuse large B-cell lymphoma.

OBJECTIVES: To compare the efficacy and side effects of salvage chemotherapy between etoposide, methylprednisolone, cytarabine and cisplatin (ESHAP) and ifosfamide, carboplatin and etoposide plus dexamethasone (DICE) for relapsed or refractory diffuse large B-cell lymphoma (DLBCL). METHODS: Medical records of patients with relapsed or refractory DLBCL receiving second-line ESHAP or DICE chemotherapy with or without rituximab from January 2007 to November 2022 were retrospectively reviewed. The primary objective was progression-free survival (PFS). The secondary objectives were overall survival (OS), overall response rate (ORR) and adverse events (AEs). RESULTS: Seventy patients were enrolled including 21 patients who received ESHAP and 49 patients who received the DICE regimen. Six patients (28.6%) and 19 patients (38.8%) in the ESHAP and DICE groups underwent ASCT, respectively. The ORR was 47.6% for ESHAP and 53.1% for DICE (p = .67). The two-year PFS was 14.3% for ESHAP and 26.5% for DICE (p = .33) with median PFS of 5 months and 14 months, respectively (hazard ratio 0.74; 95% CI 0.39-1.36, p = .330). The two-year OS was 14.3% for ESHAP and 26.5% for DICE (p = .37) with median OS of 8 months and 19 months, respectively. Patients in ESHAP group have more all-grade renal impairment than DICE group (23.8% vs. 6.1%, p = .047). DISCUSSION AND CONCLUSIONS: Efficacy between ESHAP and DICE regimens as salvage chemotherapy for relapsed or refractory DLBCL was not significantly different in terms of two-year PFS, two-year OS and ORR. DICE regimen had less renal AE than ESHAP.

Comparison of efficacy and toxicity according to etoposide and cytarabine dosing in BEAM conditioning followed by autologous stem cell transplantation in Hodgkin lymphoma.

The combination of carmustine, etoposide, cytarabine, and melphalan (BEAM) followed by autologous stem cell transplantation (ASCT) is a commonly used intensification regimen for patients with Hodgkin lymphoma. As etoposide and cytarabine dosing are not defined, we conducted a retrospective, multicenter study, to compare efficacy and toxicity in 130 patients with Hodgkin lymphoma receiving etoposide and cytarabine at either 200 mg/m2/d (n = 50), 400 mg/m2/d (n = 35), or etoposide 200 mg/m2/d and cytarabine 400 mg/m2/d (n = 45). Progression-free survival and overall survival were not associated with the intensity of conditioning. Increased conditioning intensity was associated with longer duration of thrombocytopenia, a higher number of transfused RBC and platelet units and a higher frequency of mucositis, but serious adverse events or infectious complications were not increased. The intensity of BEAM regimen was not associated with survival but with the rate of cytopenia and mucositis advocating for the use of lower dosing in frail patients.

Chemoimmunotherapy in patients with extensive-stage small cell lung cancer and a poor performance status.

BACKGROUND: Immune checkpoint inhibitor combined with platinum-etoposide is the standard first-line therapy for patients with extensive-stage small cell lung cancer (ES-SCLC). The phase 3 clinical trials that led to the approval of chemoimmunotherapy in ES-SCLC excluded patients who had an Eastern Cooperative Group (ECOG) performance status (PS) of 2-3. Therefore, data on the efficacy of chemoimmunotherapy in patients with an ECOG PS of 2-3 are limited. METHODS: A retrospective analysis was performed on patients diagnosed with ES-SCLC who received chemoimmunotherapy (atezolizumab or durvalumab) within the Mayo Clinic Health System between January 2016 and January 2021. The objective of this study was to compare the overall survival (OS), progression-free survival (PFS), and best clinical response to therapy in patients with an ECOG PS of 0-1 vs. patients with an ECOG PS of 2-3 who received chemoimmunotherapy for newly diagnosed ES-SCLC. RESULTS: In total, 82 patients were included in the study. The mean ± standard deviation age was 68.1 ± 8.3 years. Of these, 56 patients were identified with an ECOG PS of 0-1, and 26 patients were identified with an ECOG PS of 2-3. The median PFS was similar regardless of ECOG PS (5.8 months [95% CI, 4.3-6.0 months] in the ECOG PS 0-1 group vs. 4.1 months [95% CI, 3.8-6.9 months] in the ECOG PS 2-3; p = .2994). The median OS was also similar regardless of ECOG PS (10.6 months [95% CI, 8.4-13.4 months] in the ECOG PS 0-1 group vs. 9.3 months [95% CI, 4.9-12.8 months]; p = .2718) in the ECOG PS 2-3 group. CONCLUSIONS: The study results demonstrated no significant difference in PFS or OS among the ECOG PS 2-3 and ECOG PS 0-1 groups. Therefore, chemoimmunotherapy should be considered for patients who have ES-SCLC with an ECOG PS of 2-3.

Anakinra versus etoposide-based therapy added to high-dose steroids for the treatment of secondary hemophagocytic lymphohistiocytosis.

OBJECTIVE: Hemophagocytic lymphohistiocytosis (HLH) is a rare life-threatening, hyperinflammatory syndrome usually treated with high-dose steroids (HDS), often complemented with adjunct therapies, such as etoposide (HLH-94 protocol). Anakinra has been reported to effectively treat HLH; however, has not been comparatively examined with etoposide-based therapies. We sought to evaluate the effectiveness and durability of these treatment approaches. METHODS: We performed a retrospective analysis of all adult patients diagnosed with secondary HLH between January 2011 and November 2022 who received anakinra and HDS, the HLH-94 protocol, HDS alone, or supportive care. RESULTS: Thirty adult patients with secondary HLH were included. Cumulative incidence (CI) of response at 30 days was 83.3%, 60%, and 36.4% for patients treated with anakinra, the HLH-94 protocol, and HDS alone, respectively. CI of relapse at 1 year was 50%, 33.3%, and 0% with the HLH-94 protocol, HDS, and anakinra and HDS, respectively. Overall survival at 1 year was higher with anakinra and HDS compared to the HLH-94 protocol, yet was not statistically significant (77.8% vs. 33.3%; hazard ratio: 0.29; p = .25). CONCLUSION: Treatment with anakinra and HDS in adults with secondary HLH was associated with higher response rates with longer survival compared with alternative therapies and should be further investigated in this setting.

'ACOPP' chemotherapy for older and less fit patients with Hodgkin lymphoma-A multicentre, retrospective study.

Management of classical Hodgkin lymphoma in older patients is challenging due to poor tolerance of the chemotherapy regimens used in younger patients. We modified the BEACOPP regimen (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisolone), whereby bleomycin and etoposide were removed and cyclophosphamide dose was reduced, for older patients with co-morbidities. Here we present data from the first 41 patients treated with 'ACOPP' across 3 centres, demonstrating that it can be delivered, with a favourable toxicity profile (TRM 2%) and promising efficacy (2-year PFS and OS, 73% (95% CI: 52-94) and 93% (95% CI: 80-100) respectively).

Relationship between immune-related adverse events and treatment effectiveness in extensive disease small cell lung cancer.

BACKGROUND: This study aimed to assess the relationship between immune response adverse events (irAEs) and treatment efficacy in patients with extensive disease small cell lung cancer (ED-SCLC). METHODS: We retrospectively evaluated the clinical effects in 40 ED-SCLC patients who had received immune-checkpoint inhibitors (ICIs), platinum agents, and etoposide between September 2019 and September 2021. We identified and compared patients belonging to two groups: irAE and non-irAE. RESULTS: Fifteen patients experienced irAEs, and 25 did not. The median progression-free survival in patients with irAE was longer than that in patients without irAE (12.6 months [95% CI: 6.3-19.3 months] vs. 7.2 months [95% CI: 5.8-7.9 months], p = 0.0108). However, the median overall survival (OS) was similar between irAE and non-irAE groups (27.6 months [95% CI: 15.4-NA] vs. 24.9 months [95% CI: 13.7-NA], p = 0.268). Seven (46.7%) in the irAE group and 20 (80%) in the non-irAE group received sequential therapy. The median OS was prolonged in patients who received first- and second-line therapy than in those who received first-line therapy alone (27.6 months [95% CI: 19.2-NA] vs. 6.6 months [95% CI: 0.3-NA], p = 0.053). Grade ≧ 3 irAEs occurred in five (12.5%) patients. Among them, grade 5 irAEs were observed in two patients, including exacerbation of polymyositis and pulmonary arterial embolism. CONCLUSION: In this study, the development of irAEs did not affect OS in patients with ED-SCLC who received platinum-based agents, etoposide, or ICI therapy. We determined that managing irAEs and administering first- and second-line therapies could contribute to prolonged OS.

Treatment patterns and clinical outcomes of extensive stage small cell lung cancer (SCLC) in the real-world evidence ESME cohort before the era of immunotherapy.

BACKGROUND: Small cell lung cancer (SCLC) is a highly aggressive entity of lung cancer with tendency toward early recurrence after first-line treatment. As per recently updated European Society for Medical Oncology recommendations, first-line treatment with up to 4 cycles of platinum-etoposide combined with immune checkpoint inhibitor (ICIs)-targeting PD-L1, is now the standard of care. The purpose of the current analysis is to identify current patient profiles and treatment strategies in real life clinical practice, and report outcomes in Extensive Stage (ES)-SCLC. METHODS: Non-interventional, retrospective, multicentre, comparative study was carried out to describe the outcome of ES-SCLC patients included in the Epidémiologie Stratégie Médico-Economique (ESME) data platform for advanced and metastatic lung cancer. Patients were selected from 34 health care facilities between January 2015 and December 2017, before the era of immunotherapy. RESULTS: 1315 patients were identified, including 64% male and 78% under 70 year-old; 24% had at least 3 metastatic sites, mainly liver metastases (43%), bone metastases (36%), brain metastases (32%). 49% received only one line of systemic treatment; 30% and 21% received 2 and 3 lines or more, respectively. Carboplatin was more frequently used than cisplatin (71% and 29%, respectively). Prophylactic cranial irradiation was infrequent (4% of patients), but 16% of patients received thoracic radiation therapy, mainly after the completion of first-line chemotherapy (72% of patients); such strategies were more frequently applied in cisplatin/etoposide than carboplatin/etoposide patients (p = 0.006 and p = 0.015, respectively). After a median follow-up time of 21.8 (95% CI: 20.9-23.3) months, median real-world Progression-Free Survival (rw-PFS) was 6.2 (95% CI: 5.7; 6.9) and 6.1 (95% CI: 5.8; 6.3) months for cisplatin/etoposide and carboplatin/etoposide doublet regimens, respectively; 24-month rwPFS and Overall Survival were 3.2% (95% CI: 2.3; 4;2) and 22.2% (95% CI: 19.4; 25.1) in the whole population, respectively. CONCLUSION: Our data provide with landmark reference findings on ES-SCLC before the immunotherapy era, and cover many aspects of the treatment strategy, while highlighting on the role of radiotherapy, subsequent lines of therapy, and the outcomes of patients. Generation of real-world data focusing on patients who received platinum-based chemotherapy combined with immune checkpoint inhibitors is under way.

Single-center retrospective study assessing the efficacy and safety of BeEAM (bendamustine, etoposide, cytarabine, melphalan) as conditioning regimen for autologous hematopoietic stem cell transplantation.

One of the most widely accepted conditioning regimens for hematopoietic stem cell transplantation (HSCT) is BEAM (carmustine, etoposide, cytarabine, melphalan). However, a recent increase in the cost of carmustine has limited its use bringing our institution to replace carmustine with bendamustine. This observational retrospective single-center study aims to report the efficacy and safety of the BeEAM regimen. 55 patients with diffuse large B-cell lymphoma (47%), Hodgkin lymphoma (25%), mantle cell lymphoma (25%), or follicular lymphoma (2%) were included. Progression-free survival (PFS) at 24 months was 75% and overall survival (OS) was 83%. Treatment-related mortality was 4%. The most common adverse effects were febrile neutropenia (98%), mucositis (72%) and colitis (60%). Our study demonstrated excellent efficacy of the BeEAM regimen. However, the toxicity profile of BeEAM significantly varies from one study to another, and guidelines suggesting optimal dose of bendamustine and supportive care are currently lacking.

Prospective Observational Study Evaluating the Prognostic Value of the G8 Screening Tool for Extensive-Stage Small Cell Lung Cancer Patients Who Received Programmed Death-Ligand 1 Inhibitor plus Platinum-Etoposide Chemotherapy.

BACKGROUND: Programmed death-ligand 1 (PD-L1) inhibitor plus platinum-etoposide chemotherapy is used as a first-line treatment for extensive-stage small cell lung cancer (ES-SCLC), regardless of age. OBJECTIVE: We examined the role of the Geriatric 8 (G8) screening tool for evaluating treatment outcomes in patients with ES-SCLC treated with PD-L1 inhibitor plus platinum-etoposide chemotherapy as first-line therapy. PATIENTS AND METHODS: Between September 2019 and October 2021, we prospectively evaluated patients with ES-SCLC treated with immunochemotherapy at ten institutions in Japan. The G8 score was assessed before treatment initiation. RESULTS: We evaluated 44 patients with ES-SCLC. Patients with G8 score > 11 had longer overall survival (OS) than those with G8 score ≤ 11 (not reached versus 8.3 months; log-rank test, p = 0.005). In univariate and multivariate analyses, G8 score > 11 [hazard ratio (HR) 0.34; 95% confidence interval (CI) 0.15-0.75; p = 0.008 and HR 0.34; 95% CI 0.14-0.82; p = 0.02, respectively) and performance status (PS) of 2 (HR 5.42; 95% CI 2.08-14.2; p < 0.001 and HR 6.94; 95% CI 2.25-21.4; p < 0.001, respectively) were independent prognostic factors for OS. Among patients with good PS (0 or 1), the OS in patients with G8 score > 11 was significantly longer than that in patients with G8 score ≤ 11 (not reached versus 12.3 months; log-rank test, p = 0.02). CONCLUSIONS: G8 score evaluation before treatment initiation was useful as a prognostic factor for ES-SCLC patients who received PD-L1 inhibitors and platinum-etoposide chemotherapy, even with good PS.

Apatinib plus etoposide in pretreated patients with advanced triple-negative breast cancer: a phase II trial.

BACKGROUND: Treatment options for pretreated triple-negative breast cancer (TNBC) are limited. This study aimed to evaluate the efficacy and safety of apatinib, an antiangiogenic agent, in combination of etoposide for pretreated patients with advanced TNBC. METHODS: In this single-arm phase II trial, patients with advanced TNBC who failed to at least one line of chemotherapy were enrolled. Eligible patients received oral apatinib 500 mg on day 1 to 21, plus oral etoposide 50 mg on day 1 to 14 of a 3-week cycle until disease progression or intolerable toxicities. Etoposide was administered up to six cycles. The primary endpoint was progression-free survival (PFS). RESULTS: From September 2018 to September 2021, 40 patients with advanced TNBC were enrolled. All patients received previous chemotherapy in the advanced setting, with the median previous lines of 2 (1-5). At the cut-off date on January 10, 2022, the median follow-up was 26.8 (1.6-52.0) months. The median PFS was 6.0 (95% confidence interval [CI]: 3.8-8.2) months, and the median overall survival was 24.5 (95%CI: 10.2-38.8) months. The objective response rate and disease control rate was 10.0% and 62.5%, respectively. The most common adverse events (AEs) were hypertension (65.0%), nausea (47.5%) and vomiting (42.5%). Four patients developed grade 3 AE, including two with hypertension and two with proteinuria. CONCLUSIONS: Apatinib combined with oral etoposide was feasible in pretreated advanced TNBC, and was easy to administer.
