RESUMEN
BACKGROUND: The poor prognosis of anaplastic thyroid cancer (ATC) patients is associated with limited effective therapeutic strategies. Multiple antiangiogenesis tyrosine kinase inhibitors (TKIs) have been applied in later-line treatment of ATC; however, the results reported in clinical trials were controversial. In this study, we reconstructed the patient-level data to pooled-analyze the survival data, responses, and adverse events. METHODS: Online databases (PubMed, Web of Science, Embase, and Cochrane CENTRAL) were searched on September 03, 2023. R software combined with the "metaSurvival" and "meta" packages were used to reconstruct the survival curves and summarize the response rates. The primary endpoints were progression-free survival (PFS) and overall survival (OS). The secondary endpoints were survival rate, objective response rate (ORR), disease control rate (DCR), and treatment-related adverse events. RESULTS: Six prospective clinical trials involving 140 ATC patients were enrolled. Four types of TKIs (imatinib, pazopanib, sorafenib, and lenvatinib) were included. When advanced ATC patients were treated with the TKIs, the median OS was 4.8 months and the median PFS was 2.6 months. The pooled ORR and DCR were 9% and 53%. Hypertension, decreased appetite, rash, and lymphopenia were the most common gradeâ ≥â 3 treatment-related adverse events. CONCLUSION: Mono-anitangiogenesis TKI therapy showed limited improvements in treating advanced ATC patients. Combining antiangiogenesis TKI therapy with chemotherapy, radiotherapy, or immunotherapy could be the direction of future studies.

Background: For patients with anaplastic thyroid cancer (ATC) without mutational driver genes, chemotherapy is suggested to be the first-line treatment option. However, the benefits of chemotherapy in treating ATC are limited. In this analysis, we collected the prospective data reported since 2010 to analyze the emerging chemotherapy-based treatments in ATC comprehensively. Methods: For this updated analysis, we searched PubMed (MEDLINE), Web of Science, Embase, and Cochrane CENTRAL databases from 1 January 2010 to 7 February 2024 for prospective clinical studies that contained chemotherapy-based treatments. This analysis was done to pool overall survival (OS), progression-free survival (PFS), objective response rates (ORRs), disease control rates (DCRs), and grade 3 or worse treatment-related adverse events (TRAEs). Results: Six prospective clinical trials with 232 patients were included. Chemotherapy was commonly combined with targeted therapy or radiotherapy. The pooled median OS was 6.0 months (95% CI 4.1-9.7), and the median PFS was 3.2 months (95% CI 1.9-6.0) in patients with ATC who received chemotherapy-based strategies. The integrated ORR and DCR were 21% (95% CI 15%-27%) and 64% (95% CI 55%-72%), respectively. Regarding the grade 3 or worse TRAE, the pooled incidence was 68% (95% CI 47%-86%). Conclusion: Although the emerging chemotherapy-based treatments showed antitumor activity in patients with ATC, these strategies failed to prolong the survival time substantially. More practical, safe, and novel therapeutic regimens for patients with ATC warrant further investigations.

Background: Tyrosine kinase inhibitors (TKIs) contribute to the treatment of patients with anaplastic thyroid cancer (ATC). Although prospective clinical studies of TKIs exhibit limited efficacy, whether ATC patients benefit from TKI treatment in real-world clinical practice may enlighten future explorations. Therefore, we conducted this effective analysis based on real-world retrospective studies to illustrate the efficacy of TKI treatment in ATC patients. Methods: We systematically searched the online databases on September 03, 2023. Survival curves were collected and reconstructed to summarize the pooled curves. Responses were analyzed by using the "meta" package. The primary endpoints were progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and disease control rate (DCR). Results: 12 studies involving 227 patients were enrolled in the study. Therapeutic strategies included: anlotinib, lenvatinib, dabrafenib plus trametinib, vemurafenib, pembrolizumab plus dabrafenib and trametinib, pembrolizumab plus lenvatinib, pembrolizumab plus trametinib, and sorafenib. The pooled median OS and PFS were 6.37 months (95% CI 4.19-10.33) and 5.50 months (95% CI 2.17-12.03). The integrated ORR and DCR were 32% (95% CI 23%-41%) and 40% (95% CI 12%-74%). Conclusion: In real-world clinical practice, ATC patients could benefit from TKI therapy. In future studies, more basic experiments and clinical explorations are needed to enhance the effects of TKIs in the treatment of patients with ATC.

BACKGROUND: Immunotherapy has revolutionized the treatment of hepatocellular carcinoma (HCC). However, whether adding immunotherapy to antiangiogenic therapy benefits patients with unresectable HCC (uHCC) more in the first-line setting remains controversial. OBJECTIVE: In this analysis, we compared the clinical outcomes of lenvatinib monotherapy with atezolizumab plus bevacizumab combination therapy in advanced uHCC in real-world clinical practice. METHODS: The MEDLINE, Embase, and Cochrane CENTRAL databases were systematically searched on 23 April 2023. The "metaSurvival" and "meta" packages of the R software (version 4.2.2) were used to summarize the survival curves and meta-analyze the survival data. Overall survival (OS) and progression-free survival (PFS) were defined as dual primary endpoints. Secondary endpoints included the objective response rate (ORR) and disease control rate (DCR). RESULTS: Overall, the pooled median OS was 18.4 months in the lenvatinib group versus 18.5 months in the atezolizumab plus bevacizumab group; the pooled median PFS was 6.9 months in the lenvatinib group versus 7.3 months in the atezolizumab plus bevacizumab group. Lenvatinib therapy showed similar OS [hazard ratio (HR): 0.91, 95% confidence interval (CI): 0.55-1.52, p = 0.72] and PFS (HR: 0.79, 95% CI: 0.56-1.12, p = 0.19) compared with atezolizumab plus bevacizumab therapy. In addition, a comparable ORR [odds ratio (OR): 0.89, 95% CI: 0.65-1.20, p = 0.44) was observed between lenvatinib and atezolizumab plus bevacizumab. CONCLUSIONS: Comprehensive analysis suggested that lenvatinib monotherapy exhibited survival outcomes comparable to those of atezolizumab plus bevacizumab combination therapy, which may provide useful insights for clinicians in future clinical practice.

BACKGROUND: Novel-fosfamides (NFOs) belong to active metabolites of ifosfamide that bypass the generation of toxic byproducts. In this analysis, we aimed to comprehensively assess the benefits and risks of NFO monotherapy or in combination with doxorubicin (DOX) versus single-drug DOX in previously untreated patients with advanced soft-tissue sarcoma (ASTS). METHODS: Online PubMed, Web of Science, Embase, and Cochrane CENTRAL databases were systematically searched on April 26, 2022. Objective response rate and disease control rate were primary outcomes. Overall survival (OS), progression-free survival (PFS), and grade ≥ 3 treatment-related adverse events were secondary outcomes. RESULTS: In all, 3 randomized clinical trials with a total of 1207 ASTS patients were eligible. DOX plus NFO combination therapy showed higher risk ratios of objective response rate (1.50, 95% CI 1.20-1.68, P = .0003) and disease control rate (1.15, 95% CI 1.05-1.27, P = .0030) compared with DOX monotherapy. Nevertheless, NFO-based monotherapy and combination therapy were found no improvements on OS (hazard ratio 0.93, 95% CI 0.52-1.65, P = .8050) and PFS (hazard ratio 0.88, 95% CI 0.54-1.43, P = .6088) against DOX. More incidences of grade 3 or worse anemia, thrombocytopenia, stomatitis, diarrhea, constipation, and febrile neutropenia were observed in NFO-based treatments. CONCLUSION: Adding NFO to DOX as first-line therapy improved the responses in ASTS patients but did not prolong OS and PFS. Grade 3 or worse treatment-related adverse events should be treated with caution during the NFO-based therapies.

BACKGROUND: Sacituzumab govitecan (SG) is an antibody-drug conjugate that targets the human trophoblast cell-surface antigen 2 to deliver SN-38 to cancer cells. In this study, we assessed the efficacy and safety of SG in patients with relapsed or refractory metastatic triple-negative breast cancer (RM-TNBC). METHODS: For this integrated analysis, from inception to January 2, 2023, we searched PubMed, Web of Science, Embase, and Cochrane library databases for prospective studies that evaluated SC in RM-TNBC patients. Primary endpoints were survival outcomes and responses. Secondary endpoints were all grade and gradeâ ≥â 3 toxicities. RESULTS: Six hundred potentially relevant records were screened. Our analysis included 3 trials (412 patients). Median overall survival was 12.9 months (95% confidence interval [CI], 11.5-14.4), progression-free survival was 5.7 months (5% CI, 5.1-6.3), and duration of objective response was 7.4 months (5% CI, 5.8-9.0). The objective response rate was 34%, and the disease control rate was 71%. Key gradeâ ≥â 3 toxicities (in over 10% of the patients) included neutropenia (46%), leukopenia (12%), febrile neutropenia (11%), diarrhea (11%), and anemia (10%). Four treatment-related deaths were reported. CONCLUSION: SG was associated with effectiveness in patients with RM-TNBC. Myelosuppression and diarrhea were the primary treatment-related adverse events.

Background: Adebrelimab showed excellent efficacy in the first-line treatment for extensive-stage small-cell lung cancer (ES-SCLC). However, whether adebrelimab is superior to durvalumab and atezolizumab remains unclear. Therefore, we, in this study, aimed to compare the survival data of adebrelimab (CAPSTONE-1 trial) with durvalumab (CASPIAN trial) and atezolizumab (IMpower133 trial) in the first-line setting of ES-SCLC patients. Methods: Online databases, including PubMed, Embase, Web of Science, and Cochrane CENTRAL, were systematically searched on December 2, 2022. The metaSurvival and IPDfromKM methods were used to analyze the summary survival curves and the reconstructed patient-level data. The main endpoints were median overall survival (OS) and progression-free survival (PFS). Results: In this analysis, survival data in the CASPIAN, IMpower133, and CAPSTONE-1 trials were collected from five published studies. The pooled median OS and PFS were 14.0 months (95% CI 11.2-16.6) and 5.6 months (95% CI 4.7-6.7) when ES-SCLC patients received chemotherapy (etoposide and cisplatin/carboplatin) and anti-PD-L1 therapy. Based on the reconstructed patient-level data, adebrelimab significantly prolonged survival outcomes against atezolizumab (OS: Hazard ratio [HR]0.76, 95% CI 0.60-0.95; PFS: HR 0.67, 95% CI 0.54-0.83) and durvalumab (OS: HR 0.75, 95% CI 0.60-0.92). Conclusion: For previously untreated ES-SCLC patients, longer survival time might be benefited from adding adebrelimab to etoposide-platinum chemotherapy. In future studies, further real-world evidence or head-to-head clinical trials are warranted to confirm the differences between the PD-L1 inhibitors.

BACKGROUND: Taxane chemotherapy represents the standard of care in the second-line setting for non-small cell lung cancer (NSCLC) patients, but immunotherapy agents pose great challenges. Whether immunotherapy/chemotherapy alone or combination therapy has more benefits remains controversial. In this study, we provided comparisons to integrate the efficacy of immunotherapy and taxane chemotherapy as second- or later-line treatments in advanced NSCLC. METHODS: PubMed, Web of Science, Embase, and Cochrane Central Register of Controlled Trials were systematically searched from inception to September 1, 2020. Randomized controlled trials comparing immunotherapy and taxane chemotherapy were enrolled in the Bayesian network analysis. Overall survival (OS) and progression-free survival (PFS) with hazard ratios (HRs) were investigated. RESULTS: Eight trials in 13 studies with 4398 patients comparing seven treatments were identified. Pembrolizumab 10 mg/kg was associated with the best improved OS, with significant differences versus docetaxel (HR 0.81, 95% credible interval [CrI] 0.74-0.88), avelumab (HR 0.84, 95% CrI 0.75-0.95), and pembrolizumab 200 mg plus docetaxel (HR 0.75, 95% CrI 0.56-1.00). Although pembrolizumab 200 mg plus docetaxel ranked the last in terms of OS, the combination therapy showed the most favorable PFS. Additionally, the anti-programmed death-ligand 1 (PD-L1) agent, avelumab, was associated with the least improvement in PFS. CONCLUSION: As second- or later-line therapeutic strategies, pembrolizumab 10 mg/kg provided the largest OS benefits and pembrolizumab 200 mg plus docetaxel improved PFS to the greatest extent. Considering that immunotherapy has been recommended to the first-line setting of NSCLC, advanced patients who have not received immunotherapy previously might be the suitable population for our findings.

BACKGROUND: Non-small-cell lung cancer (NSCLC) harboring human epidermal growth factor receptor 2 (HER2) exon 20 mutant occurs in 3% of NSCLCs. Targeted agents for this population remain an unmet need. In this analysis, we pooled-analyzed the efficacy and safety of poziotinib, a novel tyrosine kinase inhibitor, in HER2 exon 20 mutant NSCLC. METHODS: PubMed, Embase, Web of Science, and Cochrane CENTRAL databases were systematically searched on March 9, 2022. The primary endpoints were objective response rate (ORR) and disease control rate. The secondary endpoint was treatment-related adverse events. RESULTS: Three prospective clinical trials, involving 126 patients, were identified. The pooled ORR and disease control rate of poziotinib in HER2 exon 20 mutant NSCLC were 27% (95% CI, 19-35) and 72% (95% CI, 64-80), respectively. Patients with G778_P780dupGSP had the highest ORR (88%; 95% CI, 33-100; nâ =â 12), followed by Y772_A775dupYVMA (20%; 95% CI, 12-30; nâ =â 88) and G776delinsVC (19%; 95% CI, 0-50; nâ =â 13). The most common grade 3 to 4 treatment-related adverse events were skin rash (36%), diarrhea (23%), and oral mucositis (13%). CONCLUSION: Poziotinib demonstrates moderate antitumor activity in previously treated HER2 exon 20 mutant NSCLC patients with a manageable safety profile. In addition, different subgroup mutations show various benefits of poziotinib treatment. Large-scale and multiarm clinical trials are warranted to confirm a suitable population and therapeutic strategies.

Background: Immunotherapy has revolutionized the treatment of advanced lung cancer. Nevertheless, it remains unclear whether adding stereotactic body radiotherapy (SBRT) to immunotherapy (IT) further improves responses and survival outcomes. Therefore, in this pooled analysis, we comprehensively compared IT plus SBRT with IT alone in patients with advanced lung cancer. Methods: Online databases, including PubMed, Web of Science, Embase, and Cochrane CENTRAL, were systematically searched on April 24, 2022. Eligible studies were randomized clinical trials comparing IT plus SBRT to IT. The primary outcomes were the objective response rate (ORR) and disease control rate (DCR). Progression-free survival (PFS) and overall survival (OS) were explored as secondary outcomes. Results: Overall, three phase 2 randomized clinical trials with a total of 146 previously treated lung cancer patients were enrolled. The median PFS and OS were 3.8 months and 9.5 months for IT plus SBRT versus 2.4 months and 6.1 months for IT. Comparing IT plus SBRT with IT alone, pooled risk ratios for ORR and DCR were 1.95 (95% confidence interval 1.07-3.53, p = 0.03) and 1.28 (0.94-1.73, p = 0.12). While pooled hazard ratios were 0.77 (0.25-2.42, p = 0.66) for PFS and 0.71 (0.16-3.21, p = 0.65) for OS, respectively. No publication bias was found across the trials. Conclusion: Compared to IT alone, the addition of SBRT improved the best response but failed to prolong the survival outcomes in treating advanced lung cancer patients. Future studies are necessary to explore new modalities of the combination of IT and SBRT.
RESUMEN
BACKGROUND: Epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) monotherapy is the standard of care in treating advanced non-small cell lung cancer (NSCLC). Nevertheless, whether adding pemetrexed-based chemotherapy to EGFR-TKI targeted therapy furtherly prolongs survival outcomes and improves responses remains controversial. Therefore, we conducted this pooled analysis to compare the efficacy and tolerability between gefitinib plus pemetrexed-based chemotherapy and gefitinib alone in the first-line treatment of advanced NSCLC patients with mutated EGFR. METHODS: We systematically searched PubMed, Web of Science, Embase, and Cochrane CENTRAL on June 23, 2022. Eligible studies were registered randomized clinical trials comparing gefitinib plus pemetrexed-based chemotherapy with gefitinib alone. The primary outcomes were overall survival (OS) and progression-free survival (PFS). Objective response rate (ORR), disease control rate (DCR), and discontinuation rate (DR) were explored as secondary outcomes. RESULTS: Eight studies within five randomized clinical trials were eligible. Gefitinib combined with pemetrexed-based chemotherapy significantly prolonged OS (hazard ratio [HR] 0.57, 95% confidence interval [CI] 0.37-0.89, p = 0.0125) and PFS (HR 0.52, 95% CI 0.39-0.70, p < 0.0001) versus gefitinib alone. In subgroup analysis, patients with EGFR exon 19 deletion and exon 21 L858R could benefit from the addition of pemetrexed-based chemotherapy to gefitinib in terms of PFS (EGFR exon 19 deletion: HR 0.50, 95% CI 0.34-0.75, p = 0.0008; EGFR exon 21 L858R: HR 0.46, 95% CI 0.26-0.82, p = 0.0079) but not OS. In addition, ORR was improved after the administration of gefitinib plus pemetrexed-based chemotherapy against gefitinib (odds ratio [OR] 1.91, 95% CI 1.44-2.55, p < 0.0001). Both strategies showed comparable DCRs (OR 1.46, 95% CI 0.94-2.26, p = 0.0952) and DRs (risk ratio [RR] 2.80, 95% CI 0.69-11.44, p = 0.1509). CONCLUSION: Compared with gefitinib alone, combining pemetrexed-based chemotherapy with gefitinib significantly improved OS and PFS in advanced EGFR-mutant NSCLC patients with acceptable tolerability. However, the accurate sub-population who could have OS benefits requires further validation.

Background: Ubiquitin-like with PHD and ring-finger domain 1 (UHRF1) has been defined as an oncogene in tumor cells. However, the role of UHRF1 in mediating metastasis in thyroid cancer remains unexplored. In this study, we aimed to investigate the metastatic function and the potential mechanisms of UHRF1 in thyroid cancer. Methods: Transwell assays were used to detect the metastatic capability of thyroid cancer. Dual-luciferase reporter assays were applied to examine the activation of transcription factors. Coimmunoprecipitation assays and immunofluorescence staining assays were used to elucidate the potential mechanisms of UHRF1 in promoting the metastasis of thyroid cancer. Results: In this study, we found that overexpression of UHRF1 promoted the metastasis of papillary thyroid cancer cells, and suppression of UHRF1 decreased the metastasis of anaplastic thyroid cancer cells. Regarding the signaling pathway in regulating metastasis, UHRF1 directly combined and activated the transcription factor c-Jun/AP-1 in the nucleus, subsequently increasing the transcription of IL-6 and MIF. Conclusion: Our results suggest that UHRF1 could induce the metastasis of thyroid cancer, and the potential signaling pathway might be that UHRF1 activates c-Jun/AP-1 to increase the expression of IL-6 and MIF. These findings provide a novel mechanism of UHRF1 and illustrate that UHRF1/AP-1 complex could be a potential therapeutic target for patients with thyroid cancer.
RESUMEN
Background: Adding induction chemotherapy to concurrent platinum-based chemoradiotherapy has significantly prolonged the survival time of patients with locoregionally advanced nasopharyngeal carcinoma. In this study, we intend to evaluate the survival outcomes, responses, and incidences of toxicities of induction chemotherapy and the differences between different strategies. Methods: A comprehensive search was conducted in PubMed, Embase, Web of Science, and Cochrane CENTRAL on August 10, 2021. Single-arm or multi-arm prospective clinical trials on induction chemotherapy without targeted therapies or immune checkpoint inhibitors were included. Primary outcomes included survival outcomes, objective response rate, and disease control rate, and the secondary outcome was the rates of grade 3 or higher treatment-related adverse events. Results: The 39 studies included in the systematic review and meta-analysis comprised 36 clinical trials and 5389 patients. The estimates for 3-year overall and fail-free survival rates were 87% and 77%. The estimates for 5-year rates of overall and fail-free survival were 81% and 73%. Gemcitabine plus platinum and docetaxel combined with 5-fluorouracil plus platinum strategies were associated with the highest rates of 3-year and 5-year overall survival. The objective response and disease control rates were 85% and 98% after the completion of induction chemotherapy. Neutropenia (27%) and nausea/vomiting (7%) were the most common grade 3 or higher treatment-related hematological and non-hematological adverse events during the induction phase. Conclusions: Different induction chemotherapeutic strategies appear to have varying effects and risks; a comprehensive summary of the survival outcomes, responses, and toxicities in clinical trials may provide a crucial guide for clinicians.
RESUMEN
Cemiplimab has been widely recommended by international guidelines to treat patients with locally advanced or metastatic cutaneous squamous cell carcinoma (CSCC). In this study, we conducted a comparative analysis to integrate the efficacy and safety data in the published prospective and retrospective studies for better understanding the application of cemiplimab. The online databases (PubMed, Cochrane CENTRAL, Web of Science, and EMBASE) were searched to find out eligible studies from inception to November 4, 2021. The "R" software and the "meta" package were used to synthesize the objective response rates (ORRs), disease control rates (DCRs), and the incidences of treatment-related adverse events (TRAEs). Overall, three retrospective studies with 398 patients and three prospective studies with 219 patients were enrolled. The pooled ORR and DCR were 53% (95% confidence interval [CI] 46-59) and 70% (95% CI 57-82) for retrospective studies versus 45% (95% CI 39-52) and 68% (95% CI 56-79) for prospective studies. In regard of toxicities, prospective studies reported much higher incidences of any grade (99% vs. 47%) and grade 3-4 TRAEs (43% vs. 15%) against retrospective studies. The most reported TRAE was fatigue, followed by diarrhea and pruritus. In addition, nine treatment-related deaths (four in retrospective studies vs. five in prospective studies) were documented. In both retrospective and prospective clinical practices, cemiplimab could be an effective regimen for locally advanced or metastatic CSCC patients, but toxicities during the treatment deserve further attention.

BACKGROUND: The prognosis of patients with relapsed Ewing sarcoma is poor. In this study, we aimed to pooled-analyze the efficacy and safety of the combination of irinotecan and temozolomide in treating patients with relapsed Ewing sarcoma. METHODS: PubMed, Cochrane CENTRAL, Web of Science, and EMBASE were systematically searched on September 27, 2021. The primary outcomes were rates of objective response and disease control, and the secondary outcomes were toxicities. RESULTS: Six retrospective studies with 184 patients were enrolled in the analysis. The median age ranged from 14 to 21. The integrated rates were 44% (95% confidence interval [CI] 31-58) for objective response and 66% (55-77) for disease control. Grade 3-4 neutropenia, thrombocytopenia, and diarrhea occurred in 8% (3-16), 7% (3-11), and 8% (5-10) of chemotherapeutic cycles, respectively. 18% (7-32) and 6% (2-11) of patients suffered grade 3-4 neutropenia and thrombocytopenia after irinotecan plus temozolomide treatment. CONCLUSION: Irinotecan plus temozolomide combination chemotherapy showed antitumor activity and an acceptable safety profile in patients with relapsed Ewing sarcoma. More future prospective studies are needed to confirm the retrospective results.

BACKGROUND: The major aim of this Bayesian network analysis was to determine the optimal treatment strategy for locoregionally advanced nasopharyngeal carcinoma (LANPC). METHOD: We systematically searched databases and extracted data from randomized clinical trials involving LANPC patients randomly assigned to receive induction chemotherapy followed by concurrent chemoradiotherapy (IC+CCRT), CCRT followed by adjuvant chemotherapy (CCRT+AC), or CCRT. RESULTS: In the network analysis, IC+CCRT was significantly better than CCRT alone for 5-year FFS (odds ratio [OR]: 1.63, 95% credible interval [CrI] 1.16-2.29), DMFS (OR: 1.56, 95% CrI 1.08-2.22), and LFRS (OR: 1.62, 95% CrI 1.02-2.59), but not OS (OR: 1.35, 95% CrI 0.92-2.00). Rank probabilities showed that IC+CCRT was ranked the best followed by CCRT+AC and CCRT for all 5-year outcomes. Although compared to IC+CCRT and CCRT, CCRT+AC did not significantly improve survival but had the highest 5-year survival rates. CONCLUSIONS: IC+CCRT could be recommended as a front-preferred primary definitive therapy for patients with LANPC.

PURPOSE: As an antipsychotic agent that targets multiple neurotransmitter receptors, olanzapine has been added to antiemetic therapies. For better understanding the application of olanzapine in antiemetic strategies for breast cancer patients who suffered anthracycline plus cyclophosphamide-induced nausea and vomiting, we comprehensively reviewed the antiemetic researches related to olanzapine and pooled-analyzed the results to confirm the efficacy and safety of olanzapine in breast cancer. METHODS: PubMed, Web of Science, EMBASE, and Cochrane CENTRAL databases were searched from inception through Sep 15, 2021. Both prospective and retrospective studies were eligible. The primary outcomes were complete response (defined as no vomiting and no use of rescue medications) and no nausea rate, and the secondary outcome was treatment-related adverse events. RESULTS: Four studies with 466 breast cancer patients were identified in the pooled analysis. In the acute period (0-24 h), the olanzapine group had significantly higher rates of complete response (71.3% vs 48.1%, odds ratio [OR]: 2.66, 95% confidence interval [CI] 1.39-5.11, p = 0.003) and no nausea (70.0% vs 43.0%, OR: 3.55, 95% CI 1.76-7.18, p = 0.04) than the placebo group, while in the delayed period, the olanzapine group was also superior to the placebo group in terms of the complete response (82.5% vs 63.3%, OR: 3.81, 95% CI 1.58-9.15, p = 0.003) and no nausea (66.3% vs 51.9%, OR: 2.08, 95% CI 1.03-4.21, p = 0.04) rates. During the overall period in prospective studies, the proportions of complete response (50.0% vs 34.2%, OR: 1.93, p = 0.04) and no nausea (51.3% vs 25.3%, OR: 3.40, p = 0.0006) in the olanzapine group were higher than those in the placebo group. CONCLUSION: Highly emetogenic chemotherapy breast patients could benefit from olanzapine-contained antiemetic therapy. Furthermore, since the cost is low, olanzapine is worth further clinical application and promotion.

BACKGROUND: Doxorubicin/Adriamycin (ADM) alone or combined with ifosfamide (IFO) (AI) is available for previously untreated advanced soft tissue sarcoma (ASTS). However, the clinical choice between them remains controversial. In this pooled analysis, we comprehensively compared the efficacy and tolerability of AI versus ADM in patients with ASTS. METHODS: PubMed, Web of Science, EMBASE, and Cochrane Library were systematically searched from inception to April 14, 2021. Eligible studies were randomized clinical trials comparing AI to ADM. The primary outcomes were overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). Discontinuation rate (DR) and toxic death (TD) were explored as secondary outcomes. RESULTS: Overall, three open-label randomized phase 2/3 clinical trials with a total of 1108 newly diagnosed ASTS patients were enrolled. Between AI and ADM, pooled hazard ratios were 0.93 (95% confidence interval 0.58-1.50, p = 0.78) for OS and 0.85 (0.57-1.25, p = 0.41) for PFS. While pooled risk ratios for ORR, DR, and TD were 1.37 (0.94-1.99, p = 0.10), 1.04 (0.74-1.46, p = 0.82), and 0.68 (0.19-2.36, p = 0.54) respectively. No publication bias was observed across the studies. CONCLUSION: In the first-line setting, adding IFO to ADM failed to benefit ASTS patients against ADM alone, even with comparable tolerability.
RESUMEN
BACKGROUND: Granulocyte-macrophage colony-stimulating factor (GM-CSF) has been demonstrated to improve the anti-cancer effects in combination with radiotherapy. However, the tolerability and safety of adding GM-CSF to radiotherapy in thoracic cancer patients need to be further explored. METHODS: Between June 2020 and Sep 2020, seven patients with thoracic cancer were treated with concurrent radiotherapy and GM-CSF (200 µg subcutaneously injected q.o.d during the radiotherapy). The primary endpoint was adverse event. RESULTS: Of seven enrolled patients, four were non-small cell lung cancer, two were small cell lung cancer, and the other one patient was thymic carcinoma. The total dose of GM-CSF that each patient received was at least 3000 µg. All patients had finished the radiotherapy and GM-CSF injection and suffered one or more any grade adverse events. Only one patient had a grade ≥3 hematological adverse event (lymphocytopenia). Grade ≥3 non-hematological toxicities were not observed during the combination treatment. The highest cell counts of white blood cell, neutrophile granulocyte, and monocyte across the treatment were 22.38×109/L,18.65×109/L, and 1.28×109/L respectively. CONCLUSIONS: The combination therapy of radiotherapy and GM-CSF (200 µg subcutaneously q.o.d) is tolerable and safe. Further studies are warranted to confirm the effects and optimal total GM-CSF injection doses in the combination of radiotherapy in thoracic cancer patients.
