RESUMEN

PURPOSE: The purpose of this study is to evaluate the pattern, appropriateness, and cost of antidiabetic drugs prescribed for patients with Type 2 diabetes at primary healthcare facilities (PHFs) in China. METHODS: We collected outpatient-visit prescriptions from 363 PHFs in 31 cities covering eastern, central, and western regions of China. The visits of adult patients with Type 2 diabetes diagnosis were collected and classified the antidiabetic medication pattern of each patient use as recommended or non-recommended according to Chinese guidelines. We then calculated the proportion of guideline-recommended patterns and the average monthly cost for each pattern, overall and by region. RESULTS: Of 33 519 prescriptions for Type 2 diabetes, most (73.9%) were for guideline-recommended antidiabetic treatments. The proportion of guideline-recommended prescriptions varied by region (eastern [75.9%], central [87.5%], and western [59.7%]). Metformin monotherapy was the most common guideline-recommended treatment in all three regions (eastern [20.1%], central [28.0%], and western [24.6%]). The most common non-guideline-recommended treatments were monotherapy of insulin (eastern [16.5%], central [5.1%], and western [25.7%]) and traditional Chinese antidiabetic medicines (eastern [5.6%], central [5.7%], and western [11.1%]). The average monthly costs were lower for guideline-recommended treatments compared to non-recommended treatments in all regions (eastern [13.6 ± 15.4 USD vs. 28.1 ± 22.0 USD], central [9.8 ± 10.9 USD vs. 28.7 ± 19.4 USD], and western [17.9 ± 21.4 USD vs. 30.3 ± 23.6 USD]). CONCLUSIONS: The majority of patients with Type 2 diabetes received guideline-recommended antidiabetic medications at PHFs in China, with only half of the prescriptions containing guideline-recommended metformin. Utilization of guideline-recommended therapies differed across regions. Tailored interventions to promote evidence-based antidiabetic prescribing are urgently needed, especially in the undeveloped western region.

RESUMEN

Herein, luminous blue carbon quantum dots (CDs) employing Anisomeles indica (Catmint) were reported with imaging, self-targeting, and therapeutic effects on triple-negative breast cancer (TNBC, MDA-MB-231) cells. The salient features of CDs generated from catmint are as follows: i) optical studies confirm CDs with excitation-dependent emission; ii) high-throughput characterization authenticates the formation of CDs with near-spherical shape with diameter ranging between 5 and 15 nm; iii) CDs induce cytotoxicity (3.22 ± 0.64 µg/ml) in triple-negative breast cancer (TNBC, MDA-MB-231) cells; iv) fluorescence microscopy demonstrates that CDs promote apoptosis by increasing reactive oxygen species (ROS) and decreasing mitochondrial membrane potential; v) CDs significantly up-regulate pro-apoptotic gene expression levels such as caspases-8/9/3. Finally, our work demonstrates that catmint-derived CDs are prospective nanotheranostics that augment cancer targeting and imaging.

RESUMEN

BACKGROUND/AIMS: Traumatic brain injury is a significant public problem with an incidence of 10 million people per year, causing the largest deaths and disabilities worldwide. Head injuries can be classified into primary and secondary head injuries. Secondary head injuries can be caused by several factors such as ischemia, cerebral edema, and neuroinflammation. AIF and MMP-9 are two parameters that can be indicators in measuring the effect of Oleuropein on traumatic brain injury in rats. Oleuropein itself has many activities such as antioxidant, anti-apoptotic, antimicrobial, anti-inflammatory, and neuroprotective. METHODS: Adult male Sprague-Dawley rats (250-350 grams) were exposed to head injury, with or without intraperitoneal administration of Oleuropein. Within 24-72 hours brain tissue was isolated for immunohistochemical analysis, ELISA, and TUNEL. AIF, GFAP, MMP-9, and HMGB-1 levels were determined using immunohistochemistry in both the control and treatment groups. Statistical analysis was made using the One-Way Analysis of Variance (ANOVA) and paired t-test. RESULTS: The results showed that Oleuropein was able to reduce AIF and MMP-9 levels in rats with traumatic brain injury. This indicates that Oleuropein has a neuroprotective effect by reducing inflammation and apoptosis. CONCLUSION: Oleuropein has a potential neuroprotective effect in traumatic brain injury by reducing inflammation and apoptosis. Therefore, Oleuropein can be considered as a potential therapeutic agent for traumatic brain injury in the future.

RESUMEN

The Hippo signaling pathway plays a pivotal role in regulating cell growth and organ size. Its regulatory effects on hepatocellular carcinoma (HCC) encompass diverse aspects, including cell proliferation, invasion and metastasis, tumor drug resistance, metabolic reprogramming, immunomodulatory effects and autophagy. Yes­associated protein 1 (YAP1), a potent transcriptional coactivator and a major downstream target tightly controlled by the Hippo pathway, is influenced by various molecules and pathways. The expression of YAP1 in different cell types within the liver tumor microenvironment exerts varying effects on tumor outcomes, warranting careful consideration. Therefore, research on YAP1­targeted therapies merits attention. This review discusses the composition and regulation mechanism of the Hippo/YAP1 signaling pathway and its relationship with HCC, offering insights for future research and cancer prevention strategies.

RESUMEN

Senescent cells are known to secrete proteins, including inflammatory cytokines and damage­associated molecular patterns. This phenomenon is known as the senescence­associated secretory phenotype (SASP). SASP in cancer stromal fibroblasts is involved in cancer growth and progression. Conversely, metformin, an antidiabetic drug, has been reported to inhibit SASP induction by inhibiting the activation of NF­κB, a regulator of SASP. To date, at least to the best of our knowledge, there have been no reports regarding cellular senescence in fibroblasts and tumor progression via the SASP­mediated paracrine pathway. The present study thus aimed to elucidate the induction mechanisms of SASP in radiation­induced fibroblasts and to determine its effects on cancer progression via the paracrine pathway. Furthermore, the present study aimed to determine whether controlling SASP using metformin suppresses cancer progression. A well­differentiated esophageal cancer cell line established by the authors' department and fibroblasts isolated and cultured from the non­cancerous esophageal mucosa of resected esophageal cancer cases were used for the experiments. Fibroblasts were irradiated with 8 Gy radiation, and the changes in the expression of the senescence markers, SA­ß­gal, p21, p16 and NF­κB were evaluated using immunofluorescent staining and western blot analysis in the presence or absence of metformin treatment. The culture supernatants of irradiated fibroblasts treated with metformin and those treated without metformin were collected and added to the cancer cells to evaluate their proliferative, invasive and migratory abilities. Vimentin and E­cadherin expression levels were also evaluated using immunofluorescent staining and western blot analysis. The expression levels of p16, p21 and NF­κB in irradiated fibroblasts were attenuated by treatment with metformin. Supernatants collected from irradiated fibroblasts exhibited the proliferative activity of esophageal cancer cells, and the promotion of migratory and invasion abilities, which may be due to epithelial­mesenchymal transition and changes in cell morphology. These reactions were confirmed to be suppressed by the addition of the supernatant of cultured fibroblasts pre­treated with metformin. On the whole, the present study demonstrates that fibroblasts in the cancer stroma may be involved in tumor progression through cellular senescence.

RESUMEN

TMEM16 proteins, which function as Ca2+­activated Cl­ channels are involved in regulating a wide variety of cellular pathways and functions. The modulators of Cl­ channels can be used for the molecule­based treatment of respiratory diseases, cystic fibrosis, tumors, cancer, osteoporosis and coronavirus disease 2019. The TMEM16 proteins link Ca2+ signaling, cellular electrical activity and lipid transport. Thus, deciphering these complex regulatory mechanisms may enable a more comprehensive understanding of the physiological functions of the TMEM16 proteins and assist in ascertaining the applicability of these proteins as potential pharmacological targets for the treatment of a range of diseases. The present review examined the structures, functions and characteristics of the different types of TMEM16 proteins, their association with the pathogenesis of various diseases and the applicability of TMEM16 modulator­based treatment methods.

RESUMEN

Kaposi sarcoma (KS) is a neoplasm of vascular origin that promotes angiogenesis and the growth of endothelial cells triggered by the Kaposi Sarcoma-associated Herpes Virus (KSHV). When associated with HIV, KSHV becomes more aggressive and rapidly evolves. The HIV-1 TAT protein can be essential in developing AIDS-associated KS by promoting angiogenesis and increasing KSHV replication. Therefore, we evaluated the genetic profile of the first exon of tat gene among groups of people living with HIV (PLHIV) with (case group, n = 36) or without KS, this later with (positive control group, n = 46) and without KSHV infection (negative control group, n = 24); all individuals under antiretroviral therapy. The genetic diversity, the DN/DS ratio, and the genetic entropy of the first exon of tat were higher in the case group, followed by the positive control group, which was higher than the negative control group. The number of tat codons under positive selection was seven in the case group, six in the positive control group, and one in the negative control group. The prevalence of HIV viral loads below the detection limit was equal in the case and positive control groups, which were lower than in the negative control group. The mean CD4+ T cell counts were higher in the negative control group, followed by the positive control group, and followed by the case group. These results emphasize the negative influence of KSHV in antiretroviral treatment, as well as the HIV-specific TAT profile among PLHIV who developed KS.

RESUMEN

OBJECTIVE: The present study aims to compare the efficacy and side effects of a platinum-containing combination regimen and platinum single-drug concurrent chemoradiotherapy (CCRT) in patients with advanced cervical cancer (CC) and to understand the prognostic factors in patients with CC. METHODS: A total of 108 cases of CC treated in Wenzhou Central Hospital were retrospectively selected. Patients in the monotherapy (single-drug) group received external pelvic radiotherapy (RT) and platinum-based single-drug chemotherapy (CT). Patients in the combined group received external pelvic RT and platinum-containing CT. The efficacy, CCRT time, 3-year survival rate after treatment and side effects were compared between the two groups, and the prognostic factors were analysed. RESULTS: The total effective rate was 74.07% in the monotherapy group and 72.22% in the combined group (p = .828). The incidences of myelosuppression, gastrointestinal reaction and abnormal liver function in the grades III-IV combined group were significantly higher than those in the monotherapy group (p < .001; p = .236; p = .022). Furthermore, the CCRT time was significantly longer in the combined group than in the monotherapy group, and the 3-year overall survival (OS) was 81.48% in the monotherapy group and 79.63% in the combined group (p = .643; p = .808). The older the age was, the higher the serum squamous cell carcinoma antigen (SCC-Ag) value before treatment and the shorter the progression-free survival time. In addition, the older the adenocarcinoma (AC) was, the shorter the OS. CONCLUSION: The efficacy of the two regimens in the treatment of advanced CC was similar. However, the side effects increased significantly during combined treatment. PROGNOSTIC FACTORS: A higher patient age, having an AC and stage of IIIa and a high SCC-Ag value before treatment resulted in a relatively low survival rate.

RESUMEN

BACKGROUND: Intimal hyperplasia is a normal adaptive feature of arteries in response to injuries, which include invasive vascular interventions. Its development limits the long-term success of bypass grafts. Various pharmacological agents have been successfully employed in experimental models to reduce the degree of intimal hyperplasia. In our study, we investigated the efficacy of dexamethasone in reducing intimal hyperplasia in rat abdominal aortas after partial transection and primary repair. METHODS: In this study, 20 Wistar Albino rats were randomly selected and divided into four groups to compare the effects of low- and high-dose dexamethasone on intima and media thickness compared to the control. Group A (n=5) was the control group, where only skin incision and laparotomy were performed. For Group B (n=5), a median laparotomy was performed, the abdominal aorta was partially transected, and repaired with an 8.0 prolene suture. Doses of 0.1 mg/kg and 0.2 mg/kg dexamethasone were administered in Group C (n=5) and Group D (n=5), respectively. After two weeks, all rats were euthanized, and the repaired abdominal aortas were excised and examined histopathologically. Intima and media thicknesses were measured using the 'Olympus AnalySIS 5' program (Olympus Corporation, Japan) after digital photos were taken. RESULTS: Based on the measurements, we demonstrated that after transection and repair of the abdominal aorta, the intima/media ratio was not significantly different between the low-dose dexamethasone and non-dexamethasone groups. The intima/media ratio was significantly lower in the high-dose dexamethasone group than in the non-dexamethasone and low-dose dexamethasone groups. CONCLUSION: After vascular interventions, dexamethasone treatment may reduce intimal hyperplasia and increase patency by providing vascular remodeling.

RESUMEN

Epithelial cells play a crucial role in asthma, contributing to chronic inflammation and airway hyperresponsiveness. m6A modification, which involves key proteins such as the demethylase fat mass and obesity-associated protein (FTO), is crucial in the regulation of various diseases, including asthma. However, the role of FTO in epithelial cells and the development of asthma remains unclear. In this study, we investigated the demethylase activity of FTO using a small-molecule inhibitor FB23 in epithelial cells and allergic inflammation in vivo and in vitro. We examined the FTO-regulated transcriptome-wide m6A profiling by methylated RNA immunoprecipitation sequencing (MeRIP-seq) and RNA-seq under FB23 treatment and allergic inflammation conditions. Immunofluorescence staining was performed to assess the tissue-specific expression of FTO in asthmatic bronchial mucosa. We demonstrated that FB23 alleviated allergic inflammation in IL-4/IL-13-treated epithelial cells and house dust mite (HDM)-induced allergic airway inflammation mouse model. The demethylase activity of FTO contributed to the regulation of TNF-α signaling via NF-κB and epithelial-mesenchymal transition-related pathways under allergic inflammation conditions in epithelial cells. FTO was expressed in epithelial, submucosal gland, and smooth muscle cells in human bronchial mucosa. In conclusion, FB23-induced inhibition of FTO alleviates allergic inflammation in epithelial cells and HDM-induced mice, potentially through diverse cellular processes and epithelial-mesenchymal transition signaling pathways, suggesting that FTO is a potential therapeutic target in asthma management.

RESUMEN

Atopic dermatitis (AD) is a chronic, non-infectious inflammatory dermatosis, with increasing prevalence in recent decades. Due to its chronic and recurrent nature, it diminishes the quality of life of patients and their families. In recent years, advances in the understanding of AD's pathophysiology have driven the development of targeted therapies such as monoclonal antibodies (mAbs) and Janus kinase inhibitors (JAKis) which modulate the immune system through specific signaling pathways, providing effective alternatives to traditional systemic immunosuppressive agents. Four targeted therapies have been approved in the USA for the treatment of severe/refractory cases: dupilumab, tralokinumab, abrocitinib, and upadacitinib. This manuscript aims to present an update on the pathophysiology of AD, describe the new treatments available, and provide an analysis of the initial results of the use of these treatments in the pediatric population. We concluded that the high cost of these treatments often limits their prescription to situations where cases of atopic dermatitis are resistant to other conventional therapeutic options or when the disease reaches a severe degree. This underscores the importance of careful and accurate decision-making in the medical management of AD to ensure the efficient use of these therapeutic resources.

RESUMEN

Burkitt lymphoma is a non-Hodgkin B-cell lymphoma with a high prevalence in the pediatric population. Abdominal manifestations are well known in sporadic Burkitt lymphoma and vary from nonspecific symptoms to intestinal obstruction due to intussusception; however, mass-like splenic involvement has been scarcely described. OBJECTIVE: To present a case of a patient with a splenic mass whose histopathological analysis revealed Burkitt lymphoma. CLINICAL CASE: A 13-year-old female patient presented with abdominal pain, progressive weight loss, and fever. Imaging studies showed a splenic mass, intestinal thickening, and ileal intussusception. Histopathological analysis of spleen biopsy revealed Burkitt lymphoma. After the first cycle of chemotherapy (BFM95-NHL protocol), abdominal symptoms resolved; no other signs suggestive of intussusception were observed, as well as a significant reduction of the splenic mass was observed. CONCLUSIONS: Burkitt lymphoma in pediatric patients can present as a well-defined splenic tumor, causing no splenomegaly. In addition, its management does not require surgery since it can be resolved with chemotherapy.

RESUMEN

Purpose: Retinal neovascularization is a significant feature of advanced age-related macular degeneration (AMD) and a major cause of blindness in patients with AMD. However, the underlying mechanism of this pathological neovascularization remains unknown. Iron metabolism has been implicated in various biological processes. This study was conducted to investigate the effects of iron metabolism on retinal neovascularization in neovascular AMD (nAMD). Methods: C57BL/6J and very low-density lipoprotein receptor (VLDLR) knockout (Vldlr-/-) mice, a murine model of nAMD, were used in this study. Bulk-RNA sequencing was used to identify differentially expressed genes. Western blot analysis was performed to test the expression of proteins. Iron chelator deferiprone (DFP) was administrated to the mice by oral gavage. Fundus fluorescein angiography was used to evaluate retinal vascular leakage. Immunofluorescence staining was used to detect macrophages and iron-related proteins. Results: RNA sequencing (RNA-seq) results showed altered transferrin expression in the retina and RPE of Vldlr-/- mice. Disrupted iron homeostasis was observed in the retina and RPE of Vldlr-/- mice. DFP mitigated iron overload and significantly reduced retinal neovascularization and vascular leakage. In addition, DFP suppressed the inflammation in Vldlr-/- retinas. The reduced signals of macrophages were observed at sites of neovascularization in the retina and RPE of Vldlr-/- mice after DFP treatment. Further, the IL-6/JAK2/STAT3 signaling pathway was activated in the retina and RPE of Vldlr-/- mice and reversed by DFP treatment. Conclusions: Disrupted iron metabolism may contribute to retinal neovascularization in nAMD. Restoring iron homeostasis by DFP could be a potential therapeutic approach for nAMD.

RESUMEN

Purpose: To explore the long-term effect of diabetic retinopathy on response to anti-vascular endothelial growth factor (VEGF) treatment in age-related macular degeneration-associated type 1 macular neovascularization (MNV) using optical coherence tomography angiography (OCTA). Methods: A total of 45 eyes with exudative neovascular age-related macular degeneration (nAMD) with type 1 MNV were included in the analysis. Among them, 24 eyes of 24 patients had no history of diabetes mellitus (DM) in their anamnesis and were assigned to the Not Diabetic group; 21 eyes of 21 patients had mild diabetic retinopathy and were included in the Diabetic group. We considered the following outcome measures: (1) best-corrected visual acuity changes; (2) central macular thickness; (3) MNV lesion area; and (4) MNV flow area. The OCTA acquisitions were performed at the following time points: (1) baseline visit, which corresponded to the day before the first injection; (2) post-loading phase (LP), which was scheduled at 1 month after the last LP injection; and (3) 12-month follow-up visit. Results: All morphofunctional parameters showed a significant improvement after the LP and at the 12-month follow-up visit. Specifically, both the Diabetic group and the Not Diabetic group displayed a significant reduction of MNV lesion areas at both the post-LP assessment (P = 0.026 and P = 0.016, respectively) and the 12-month follow-up (P = 0.039 and P = 0.025, respectively). Similarly, the MNV flow area was significantly decreased in both the Diabetic group and the Not Diabetic group at the post-LP assessment (P < 0.001 and P = 0.012, respectively) and at the 12-month follow-up (P = 0.01 and P = 0.035, respectively) compared to baseline. A smaller reduction in the MNV lesion area was observed in the Diabetic group at both the post-LP evaluation (P = 0.015) and the 12-month follow-up (P = 0.032). No other significant differences were found between the groups for the other parameters (P > 0.05). Conclusions: Our results indicated that the Diabetic group exhibited a smaller reduction in MNV lesion area after 12 months of anti-VEGF treatment. This highlights the importance of considering diabetic retinopathy as a potential modifier of treatment outcomes in nAMD management, with DM serving as a crucial risk factor during anti-angiogenic treatment.

RESUMEN

Mushrooms produce many metabolites that show biological activity, which can be obtained from their fruiting body, mycelium or recovered from the culture broth when mushrooms are grown in submerged fermentation. Mushrooms are a source of natural pharmaceuticals; they have been reported to have potential inhibitory or preventive activity against some diseases, including different types of cancer. Cancer represents one of the main causes of death worldwide. It is worth mentioning that despite advances in pharmacological treatments, they still present side effects in patients. In this sense, the study of the use of mushrooms in complementary treatments against cancer is of great interest. Based on studies carried out in vitro and, in some cases, using animal models, it has been observed that mushrooms present preventive, corrective, and therapeutic properties against different types of cancer, by stimulating the immune system, due to their antioxidant, antimutagenic, and anti-inflammatory activities, as well as the regulation of the expression of some cellular processes, cell cycle arrest, and apoptosis, etc. Based on the above, this manuscript shows a review of scientific studies that support the anticancer activity of some mushrooms and/or their bioactive compounds.

RESUMEN

Importance: The prognosis of patients with adenocarcinoma of the esophagus and esophagogastric junction (AEG) is poor. From current evidence, it remains unclear to what extent preoperative chemoradiotherapy (CRT) or preoperative and/or perioperative chemotherapy achieve better outcomes than surgery alone. Objective: To assess the association of preoperative CRT and preoperative and/or perioperative chemotherapy in patients with AEG with overall survival and other outcomes. Data Sources: Literature search in PubMed, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, ClinicalTrials.gov, and International Clinical Trials Registry Platform was performed from inception to April 21, 2023. Study Selection: Two blinded reviewers screened for randomized clinical trials comparing preoperative CRT plus surgery with preoperative and/or perioperative chemotherapy plus surgery, 1 intervention with surgery alone, or all 3 treatments. Only data from participants with AEG were included from trials that encompassed mixed histology or gastric cancer. Among 2768 initially identified studies, 17 (0.6%) met the selection criteria. Data Extraction and Synthesis: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines were followed for extracting data and assessing data quality by 2 independent extractors. A bayesian network meta-analysis was conducted using the 2-stage approach. Main Outcomes and Measures: Overall and disease-free survival, postoperative morbidity, and mortality. Results: The analyses included 2549 patients (2206 [86.5%] male; mean [SD] age, 61.0 [9.4] years) from 17 trials (conducted from 1989-2016). Both preoperative CRT plus surgery (hazard ratio [HR], 0.75 [95% credible interval (CrI), 0.62-0.90]; 3-year difference, 105 deaths per 1000 patients) and preoperative and/or perioperative chemotherapy plus surgery (HR, 0.78 [95% CrI, 0.64-0.91]; 3-year difference, 90 deaths per 1000 patients) showed longer overall survival than surgery alone. Comparing the 2 modalities yielded similar overall survival (HR, 1.04 [95% CrI], 0.83-1.28]; 3-year difference, 15 deaths per 1000 patients fewer for CRT). Similarly, disease-free survival was longer for both modalities compared with surgery alone. Postoperative morbidity was more frequent after CRT plus surgery (odds ratio [OR], 2.94 [95% CrI, 1.01-8.59]) than surgery alone. Postoperative mortality was not significantly more frequent after CRT plus surgery than surgery alone (OR, 2.50 [95% CrI, 0.66-10.56]) or after chemotherapy plus surgery than CRT plus surgery (OR, 0.44 [95% CrI, 0.08-2.00]). Conclusions and Relevance: In this meta-analysis of patients with AEG, both preoperative CRT and preoperative and/or perioperative chemotherapy were associated with longer survival without relevant differences between the 2 modalities. Thus, either of the 2 treatments may be recommended to patients.

RESUMEN

IMPORTANCE: The association between obesity and response to cancer treatment and survival remains unclear, with conflicting findings from various studies. The optimal choice between conventional chemotherapy and immunotherapy for first-line treatment remains uncertain in patients with obesity who potentially have an inadequate therapeutic response to immunotherapy. OBJECTIVE: To investigate whether body mass index (BMI) modifies the association of immunotherapy or conventional therapy with overall survival in patients with advanced non-small cell lung cancer (aNSCLC). DESIGN, SETTING, and PARTICIPANTS: A retrospective cohort study, using administrative claims data obtained from advanced treatment centers in Japan, was conducted between December 1, 2015, and January 31, 2023. Participants included individuals aged 18 years or older with aNSCLC who received immunotherapy, using immune checkpoint inhibitor (ICI) treatment or conventional chemotherapy. EXPOSURE: Immune checkpoint inhibitor therapy as first-line chemotherapy was compared with conventional chemotherapy, identified through patient medical records. MAIN OUTCOMES AND MEASURES: The main outcome was overall survival. Survival analysis covered a 3-year follow-up period after the first-line chemotherapy. RESULTS: A total of 31 257 patients with aNSCLC were identified. Of these, 12 816 patients received ICI therapy (mean [SD] age, 70.2 [9.1] years; 10 287 [80.3%] men) and 18 441 patients received conventional chemotherapy (mean [SD] age, 70.2 [8.9] years; 14 139 [76.7%] men). Among patients with BMI less than 28, ICI therapy was associated with a significantly lower hazard of mortality (eg, BMI 24: hazard ratio [HR], 0.81; 95% CI, 0.75-0.87) compared with those who underwent conventional chemotherapy. However, no such association was observed among patients with BMI 28 or greater (eg, BMI 28: HR, 0.90; 95% CI, 0.81-1.00). CONCLUSIONS AND RELEVANCE: The findings of this retrospective cohort study suggest that BMI modifies the association of ICI therapy compared with conventional chemotherapy with overall survival in patients with aNSCLC. A lack of association between ICI therapy and improved survival in patients with aNSCLC and overweight or obesity compared with conventional chemotherapy was observed. This suggests that ICI therapy may not be the optimal first-line therapy for patients with overweight or obesity and the use of conventional chemotherapy should also be considered in such patients.
