OBJECTIVE: To study the clinical effects of pomalidomide-based regimen in the treatment of relapsed and refractory multiple myeloma (RRMM). METHODS: 60 patients with RRMM in hematology department of the First Affiliated Hospital of Xinxiang Medical University from November 2020 to January 2023 were selected. Among them, 15 cases were treated with PDD regimen (pomalidomide + daratumumab + dexamethasone), and 45 cases were treated with PCD regimen (pomalidomide + cyclophosphamide + dexamethasone). The clinical effects were evaluated. RESULTS: The median number of treatment cycles for the entire cohort was 5 (2-11), with an overall response rate (ORR) of 75.0%. The ORR of patients treated with PDD regimen was 73.3%, while the ORR of patients treated with PCD regimen was 75.6%. The ORR of 46 patients with non high-risk cytogenetic abnormalities (non-HRCA) was 86.9%, significantly higher than the 35.7% of 14 patients with HRCA (χ² =15.031, P < 0.05). The median PFS for all patients was 8.0(95%CI : 6.8-9.1) months and the median OS was 14.0 (95%CI : 11.3-16.7) months. Among patients treated with PDD regimen, the PFS and OS of patients with non-HRCA were significantly higher than those of patients with HRCA [PFS: 7.0(95%CI : 4.6-9.3) months vs 4.0(95%CI : 3.1-4.8) months, χ² =5.120, P < 0.05; OS: not reached vs 6.0(95%CI : 1.1-10.9) months, χ² =9.870, P < 0.05]. Among patients treated with PCD regimen, the PFS and OS of patients with non-HRCA were significantly higher than those of patients with HRCA [PFS: 9.0(95%CI : 6.2-11.8) months vs 6.0(95%CI : 5.4-6.6) months, χ²=14.396, P < 0.05; OS: not reached vs 11.0(95%CI : 6.4-15.6) months, χ² =7.471, P < 0.05]. CONCLUSION The pomalidomide-based regimen has a good clinical effect and safety in the treatment of RRMM.

OBJECTIVE: To investigate the efficacy and safety of combination regimen containing daratumumab in multiple myeloma (MM) patients. METHODS: The clinical data of 14 newly diagnosed MM patients and 58 relapsed refractory MM patients treated with combination regimen containing daratumumab from November 2020 to March 2023 in the First Affiliated Hospital of Nanchang University were retrospectively analyzed. The efficacy and safety of combination regimen were analyzed. RESULTS: The median age of the 72 patients was 62 (38-78) years, including 35 males and 37 females. The overall response rate (ORR) of patients receiving first-line, second-line, and third-line or above treatment was 92.9% (13/14), 68.2% (30/44), and 42.9% (6/14), respectively. The median progression-free survival (PFS) was not reached, 15.4 months, and 9.7 months in three groups, respectively (all P <0.05), while the median overall survival (OS) was all not reached. Among relapsed refractory patients, the ORR of those treated with DVd, DPd and DRd regimen was 50.0% (12/24), 40.0% (4/10) and 100% (10/10), the median PFS was 2.8 months, 10.3 months and not reached, and the median OS was 15.4 months, not reached and not reached, respectively. Furthermore, the PFS and OS in the DRd group were superior to those in the other two groups (all P <0.05). Cox univariate and multivariate analysis showed that lactate dehydrogenase (LDH) ≥250 U/L and extramedullary disease were independent adverse prognostic factors for PFS, and LDH ≥250 U/L was also an independent adverse prognostic factor for OS. Hematologic adverse reactions were mainly lymphopenia (87.5%) and thrombocytopenia (52.8%), while non-hematologic adverse reactions were mainly infusion-related reactions (19.4%) and infections (11.1%). CONCLUSIONS The combination regimens containing daratumumab can be used as first-line treatment for patients with newly diagnosed MM. In patients with relapsed refractory MM, early use of regimens containing daratumumab may improve treatment response rate and prolong PFS. The DRd regimen has better therapeutic response and survival advantages. LDH is an independent prognostic factor affecting PFS and OS in MM patients.

OBJECTIVE: To investigate the effect of daratumumab, lenalidomide and dexamethasone on quality of life in transplant-ineligible (TIE) patients with newly diagnosed multiple myeloma (NDMM). METHODS: The clinical data of 93 TIE NDMM patients in our hospital from January 2020 to December 2022 were retrospectively analyzed. The patients were divided into D-Rd group (48 cases) and Rd group (45 cases) according to treatment regimen. The patients in Rd group were treated with lenalidomide and dexamethasone, while those in D-Rd group were treated with daratumumab on the basis of Rd group. The QLQ-C30 and EQ-5D VAS scores of the two groups were compared at baseline and after 3, 6 and 12 treatment cycles. The last follow-up date was June 30, 2023, and overall survival (OS) was compared between the two groups. RESULTS: The median follow-up period in the D-Rd group was 21 (7-38) months, and the median OS was 34 months, while that in the Rd group was 16 (5-35) months, and the median OS was 28 months. There was significant difference in OS between the two groups ( P <0.05). After 3, 6 and 12 treatment cycles, the QLQ-C30 score and EQ-5D VAS score of the two groups were significantly improved (all P <0.05). After 3 and 12 treatment cycles, the QLQ-C30 score and EQ-5D VAS score of D-Rd group were significantly higher than those of Rd group (all P <0.05). There were no significant differences in the improvement of QLQ-C30 GHS and pain scores between the two groups of patients with age <75 years and ECOG 0-1 score after 3, 6 and 12 treatment cycles (P >0.05). In D-Rd group of patients with age≥75 years, the improvement of QLQ-C30 GHS scores after 3 and 12 treatment cycles and QLQ-C30 pain scores after 3, 6 and 12 treatment cycles was significantly superior to that in Rd group (all P <0.05). In D-Rd group of patients with ECOG 2 scores, the improvement of QLQ-C30 GHS and pain scores after 3, 6 and 12 treatment cycles was significantly superior to that in Rd group (all P <0.05). CONCLUSION Daratumumab, lenalidomide, and dexamethasone can significantly improve OS in TIE NDMM patients without decrease of quality of life, especially in those with age≥75 years or ECOG 2 scores.

Programmed cell death 1 (PD-1) inhibitor therapy for lung adenocarcinoma may induce rare but severe hematologic adverse events, including severe anemia. Although glucocorticoids are recommended for managing immune-related adverse events, therapeutic experience with PD-1 inhibitor-induced severe anemia remains limited, and its efficacy and safety have not been fully validated. This article reports a case of advanced lung adenocarcinoma in which severe anemia developed following combination therapy with chemotherapy and PD-1 inhibitor. After comprehensive evaluation, the patient was diagnosed with anemia of inflammation (AI) and achieved significant hemoglobin recovery following high-dose glucocorticoid treatment. These findings may provide new insights into the recognition and management of this rare hematologic toxicity in clinical practice.

Chronic rhinosinusitis（CRS） is a chronic inflammation of the nasal cavity and sinus mucosa, which is mainly characterized by nasal obstruction, runny nose, headache and hyposmia. Due to complex mechanisms, CRS can be divided into different clinical phenotypes and inflammatory endotypes. Approximately 80% of chronic rhinosinusitis with nasal polyps（CRSwNP） patients present with type Ⅱ inflammation. IL-4 and IL-13 are the key factors in the process of type Ⅱ inflammation, and drugs targeting IL-4/IL-13 provide new options for the treatment of CRSwNP. Therefore, this article mainly reviews the application of anti-IL-4 /IL-13 monoclonal antibody in CRSwNP.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.

OBJECTIVE: Recaticimab (SHR-1209) significantly reduces low-density lipoprotein cholesterol levels. However, its effect on glucose metabolism remains unclear. This study aimed to evaluate its effect on glycemic parameters in a Chinese population. METHODS: Recaticimab versus placebo was administered in a 5:1 ratio to 110 hyperlipidemia patients who were followed up for 24 weeks. Glycated hemoglobin (HbA1c) levels were measured at baseline every 12 weeks. Fasting plasma glucose (FPG) levels were measured at baseline at week 1, 3, 5, 8, 12, 16, 20, and 24. Repeated-measures mixed-effects models were used to determine the longitudinal association between reacticimab and FPG and HbA1c levels. RESULTS: Among the 81 participants with normal glucose metabolism, HbA1c levels significantly decreased ( F = 4.568, P = 0.036). In the 29 participants with abnormal glucose metabolism, a significant time effect was observed for FPG levels ( F = 2.492, P = 0.016). For participants with normal and abnormal glucose metabolism, no significant group × time interaction effects on FPG or HbA1c levels were identified. CONCLUSION Recaticimab showed no adverse glycemic effects in participants with normal or abnormal glucose metabolism, indicating its safety in patients with or without diabetes.

BACKGROUND: The purpose of this study was to evaluate the safety and efficacy of subsequent radiotherapy (RT) following first-line treatment with durvalumab plus chemotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC). METHODS: A total of 122 patients with ES-SCLC from three hospitals during July 2019 to December 2021 were retrospectively analyzed. Inverse probability of treatment weighting (IPTW) analysis was performed to address potential confounding factors. The primary focus of our evaluation was to assess the impact of RT on progression-free survival (PFS) and overall survival (OS). RESULTS: After IPTW analysis, 49 patients received durvalumab plus platinum-etoposide (EP) chemotherapy followed by RT (Durva + EP + RT) and 72 patients received immunochemotherapy (Durva + EP). The median OS was 17.2 months vs . 12.3 months (hazard ratio [HR]: 0.38, 95% confidence interval [CI]: 0.17-0.85, P = 0.020), and the median PFS was 8.9 months vs . 5.9 months (HR: 0.56, 95% CI: 0.32-0.97, P = 0.030) in Durva + EP + RT and Durva + EP groups, respectively. Thoracic radiation therapy (TRT) resulted in longer OS (17.2 months vs . 14.7 months) and PFS (9.1 months vs . 7.2 months) compared to RT directed to other metastatic sites. Among patients with oligo-metastasis, RT also showed significant benefits, with a median OS of 17.4 months vs . 13.7 months and median PFS of 9.8 months vs . 5.9 months compared to no RT. Continuous durvalumab treatment beyond progression (TBP) prolonged OS compared to patients without TBP, in both the Durva + EP + RT (NA vs . 15.8 months, HR: 0.48, 95% CI: 0.14-1.63, P = 0.238) and Durva + EP groups (12.3 months vs . 4.3 months, HR: 0.29, 95% CI: 0.10-0.81, P = 0.018). Grade 3 or 4 adverse events occurred in 13 (26.5%) and 13 (18.1%) patients, respectively, in the two groups; pneumonitis was mostly low-grade. CONCLUSION Addition of RT after first-line immunochemotherapy significantly improved survival outcomes with manageable toxicity in ES-SCLC.

BACKGROUND: Durvalumab after chemoradiotherapy (CRT) failed to bring survival benefits to patients with epidermal growth factor receptor ( EGFR ) mutations in PACIFIC study (evaluating durvalumab in patients with stage III, unresectable NSCLC who did not have disease progression after concurrent chemoradiotherapy). We aimed to explore whether locally advanced inoperable patients with EGFR mutations benefit from tyrosine kinase inhibitors (TKIs) and the optimal treatment regimen. METHODS: We searched the PubMed, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases from inception to December 31, 2022 and performed a meta-analysis based on a Bayesian framework, with progression-free survival (PFS) and overall survival (OS) as the primary endpoints. RESULTS: A total of 1156 patients were identified in 16 studies that included 6 treatment measures, including CRT, CRT followed by durvalumab (CRT-Durva), TKI monotherapy, radiotherapy combined with TKI (RT-TKI), CRT combined with TKI (CRT-TKI), and TKI combined with durvalumab (TKI-Durva). The PFS of patients treated with TKI-containing regimens was significantly longer than that of patients treated with TKI-free regimens (hazard ratio [HR] = 0.37, 95% confidence interval [CI], 0.20-0.66). The PFS of TKI monotherapy was significantly longer than that of CRT (HR = 0.66, 95% CI, 0.50-0.87) but shorter than RT-TKI (HR = 1.78, 95% CI, 1.17-2.67). Furthermore, the PFS of RT-TKI or CRT-TKI were both significantly longer than that of CRT or CRT-Durva. RT-TKI ranked first in the Bayesian ranking, with the longest OS (60.8 months, 95% CI = 37.2-84.3 months) and the longest PFS (21.5 months, 95% CI, 15.4-27.5 months) in integrated analysis. CONCLUSIONS: For unresectable stage III EGFR mutant NSCLC, RT and TKI are both essential. Based on the current evidence, RT-TKI brings a superior survival advantage, while CRT-TKI needs further estimation. Large randomized clinical trials are urgently needed to explore the appropriate application sequences of TKI, radiotherapy, and chemotherapy.
