[Analysis of clinical and prognostic characteristics of newly diagnosed multiple myeloma with myelofibrosis patients].

Objective: To investigate the clinical and prognostic characteristics of newly diagnosed multiple myeloma (NDMM) patients with myelofibrosis (MF). Methods: The clinical data of 160 NDMM patients admitted to Henan Provincial People's Hospital from January 2012 to July 2022 were analyzed retrospectively. They were divided into MF group(n=74) and non-MF group(n=86) according to whether combined with MF. Patients in MF group were further splited into MF-1 group (n=47) and MF-2/3 group (n=27). All patients were treated with bortezomib and immunomodulatory-based combination therapy. The efficacy was evaluated after 4 courses, and the clinical features and prognosis between the two groups were compared. The deadline for follow-up was December 30, 2022 and the median follow-up period [M (Q1, Q3)] was 23.5 (14.4, 40.5) months. Kaplan-Meier method was used for survival analysis, and Cox regression model was used to analyze the influencing factors of survival. Results: Among 160 patients with NDMM, 91 were males and 69 were females, with a median age [M (Q1, Q3)] of 59 (54, 69) years. In MF group, the bone marrow immature plasma cell percentage, total plasma cell percentage were 9.6% (3.2%, 28.5%) and 36.4% (18.5%, 51.1%), respectively, which were higher than 6.0% (1.2%, 17.2%) and 24.0% (12.0%, 46.0%) of the non-MF group (both P<0.05). Hb level was 84.0(74.5, 100.5)g/L and PLT was (151.99±90.68) ×109/L in the MF group, which were lower than 96.0 (81.0, 112.0)g/L and (180.38±85.32) ×109/L of non-MF group (both P<0.05). But there were no significant differences in ISS stage, karyotypic and fluorescence in situ hybridization (FISH) high-risk genetic abnormalities between the two groups (all P>0.05). Objective response rate (ORR), overall survival (OS) and progression-free survival (PFS) were not significantly different between the two groups (all P>0.05). The rate of 17p- was 25.9% (7/27) in MF-2/3 group, which was higher than 8.1% (7/86) of non-MF group (P=0.049). The median OS of the MF-2/3 group was 25.0 (95%CI: 23.6-26.4) months, which was shorter than that of the non-MF group (54.0 months, P=0.031). Multivariate Cox regression analysis showed that grade MF-2/3 was not a risk factor for OS in NDMM patients (HR=1.507, 95%CI: 0.624-3.993, P=0.425). Conclusions: The ratio of bone marrow immature plasma cells and total plasma cells in NDMM patients with MF are higher than that in patients without MF, and the Hb and PLT are lower than that in patients without MF. NDMM patients with grade 2/3 MF have shorter survival than those without MF.

[Efficacy and feasibility of catheter-based adrenal ablation on Cushing's syndrome associated hypertension].

Objective: To explore the value of catheter-based adrenal ablation in treating Cushing's syndrome (CS)-associated hypertension. Methods: A clinical study was conducted in patients with CS, who received catheter-based adrenal ablation between March 2018 and July 2023 in Daping Hospital. Parameters monitored were blood pressure (outpatient and 24-hour ambulatory), body weight, clinical characteristics, serum cortisol and adrenocorticotropic hormone (ACTH) at 8 am, 24-hour urinary free cortisol (24 h UFC), fasting blood glucose and postoperative complications. Procedure effectiveness was defined as blood pressure returning to normal levels (systolic blood pressure<140 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure<90 mmHg), cortisol and 24 h UFC returning to normal and improvement of clinical characteristics. The parameters were monitored during follow up in the outpatient department at 1, 3, 6, and 12 months after catheter-based adrenal ablation. Results: A total of 12 patients (aged (40.0±13.2) years) were reviewed. There were 5 males, with 5 cases of adenoma and 7 with hyperplasia from imaging studies. Catheter-based adrenal ablation was successful in all without interruption or surgical conversion. No postoperative complication including bleeding, puncture site infection, adrenal artery rupture or adrenal bleeding was observed. The mean follow up was 28 months. Compared to baseline values, body weight declined to (59.48±11.65) kg from (64.81±10.75) kg (P=0.008), fasting blood glucose declined to (4.54±0.83) mmol from (5.53±0.99) mmol (P=0.044), outpatient systolic blood pressure declined to (128±21) mmHg from (140±19) mmHg (P=0.005), diastolic blood pressure declined to (78±10) mmHg from (86±11) mmHg (P=0.041), and the mean ambulatory daytime diastolic blood pressure declined to (79±12) mmHg from (89±8) mmHg (P=0.034). Catheter-based adrenal ablation in 8 patients was defined as effective with their 24 h UFC significantly reduced after the procedure (1 338.41±448.06) mmol/L from (633.66±315.94) mmol/L, P=0.011). The change of 24 h UFC between the effective treatment group and ineffective group was statistically significant (P=0.020). The postoperative systolic blood pressure in the treated adenoma group was significantly lower than those of hyperplasia group (112±13) mmHg vs. (139±20) mmHg, P=0.026). Conclusions: For patients with CS-associated hypertension who are unwilling or unable to undergo surgical treatment, catheter-based adrenal ablation could improve the blood pressure and cortisol level. Catheter-based adrenal ablation could be a safe, effective, and minimally invasive therapy. However, our results still need to be validated in further large-scale studies.

IL-17A as a new circulating bioindicator for non-small cell lung cancer diagnosis and prognosis.

OBJECTIVE: Lung cancer (LC) is the highest contributor to cancer-associated mortality worldwide. Approximately 85% of all LC incidences involve non-small cell LC (NSCLC). Unfortunately, owing to a significant lack of sensitive and robust bioindicators, most patient diagnoses occur at advanced stages of the disease, thereby resulting in extremely poor patient outcomes. Herein, we elucidated the role of interleukin-17A (IL-17A) among NSCLC patients. MATERIALS AND METHODS: Circulating IL-17A content was measured using enzyme-linked immunosorbent assay (ELISA), and its diagnostic and prognostic abilities were assessed using the receiver operating characteristic (ROC) curve and Kaplan-Meier analysis, respectively. RESULTS: Our analysis revealed that circulating IL-17A levels were significantly augmented among NSCLC vs. control samples. Moreover, based on our area under the curve (AUC) analysis, circulating IL-17A levels fared considerably better than the standard bioindicator carcinoembryonic antigen (CEA) in both testing and validation cohorts. Notably, we also revealed that the circulating IL-17A levels were accurately and reliably predicted in early-stage NSCLC patients. Besides, we demonstrated a strong correlation between elevated circulating IL-17A expression and worse prognosis among NSCLC patients. CONCLUSIONS: Herein, we demonstrated that circulating IL-17A levels can serve as reliable and potent diagnostic and prognostic bioindicators for NSCLC.

[Evaluation of bladder function and sleep patterns in children with primary mono-symptomatic nocturnal enuresis by polysomnography combined with ambulatory urodynamic monitoring].

Objective: To evaluate the bladder function and sleep pattern in the children with primary mono-symptomatic nocturnal enuresis (PMNE) by the polysomnography (PSG) and ambulatory urodynamic monitoring (AUM). Methods: From October 2019 to October 2021, forty-three patients with PMNE were selected as PMNE group from the First Affiliated Hospital of Zhengzhou University and further subdivided into the severe PMNE group (enuresis>4 times/week) and the non-severe PMNE group (enuresis times 4 times/week) according to the severity. The conventional urodynamics (CUD), AUM, and PSG examinations and bladder diary were completed in the PMNE group. The control group consisted of 23 children with normal PSG findings and without the lower urinary tract symptoms. Results: The severe PMNE group included 9 males and 14 females, aged(12.1±3.2)years, and nocturnal enuresis number per week is 6.7±1.7. The non-severe PMNE group included 9 males and 11 females, aged(12.0±3.4)years, and nocturnal enuresis number per week is 2.3±1.0. The incidences of nocturnal polyuria and the reduction in maximum bladder capacity in the PMNE group was 34.9% and 11.6%, respectively. The incidence and frequency of detrusor overactivity (DO) in the severe PMNE group were significantly higher than those in the non-severe PMNE group [78.3% vs 45.0%, (5.5±1.8) times/h vs (3.4±1.0) times/h, respectively, all P<0.05]. It was found by the PSG that the severe PMNE group had significantly higher cortical arousal index, apnea hypopnea index (AHI), and percentage of N1+N2 phase in total sleep time, compared with the control group[(58.6±9.8)% vs (49.3±9.5)%, (9.4±4.4) times/h vs (3.1±1.5) times/h, (2.7±0.9) times/h vs (0.9±0.7) times/h] (all P<0.05). While the sleep efficiency of the severe PMNE group was substantially lower than that of the non-severe PMNE group [(86.4±4.3)% vs (91.0±3.9)%], the cortical arousal index and AHI were significantly greater than those of the non-severe PMNE group[(9.4±4.4) times/h vs (5.7±3.2) times/h, (2.7±0.9) times/h vs (1.9±0.7) times/h] (all P<0.05). In the PMNE group, there were positive correlations between cortical arousal index and nocturnal DO frequency or AHI (r=0.705, 0.765, P=0.001). Conclusions: Children with PMNE have nocturnal bladder dysfunction and abnormal sleep pattern, and there is a certain correlation between them. PSG and AUM are necessary for the evaluation and treatment of children with PMNE.

[Characteristics and prognostic effects of NOTCH1/FBXW7 gene mutations in T-cell acute lymphoblastic leukemia patients].

Objective: To explore the characteristics, clinical features and prognostic effects of NOTCH1/FBXW7 gene mutations in T-cell acute lymphoblastic leukemia (T-ALL) patients. Methods: The clinical data of 61 T-ALL patients who underwent second-generation gene sequencing in Henan Provincial People's Hospital from March 2016 to March 2021 were retrospectively analyzed. There were 46 males and 15 females, with a median age [M (Q1, Q3)] of 18 (11, 30) years. The relationship between NOTCH1/FBXW7 gene mutation characteristics, clinical and laboratory parameters and their impact on event free survival (EFS) and overall survival (OS) were analyzed. Results: NOTCH1 gene mutations were found in 34 cases (55.7%, 34/61), including 22 cases of heterodimer domain (HD) mutations (64.7%), 7 cases of proline/glutamate/serine/threonine (PEST) mutations (20.6%), and 5 cases of both HD and PEST mutations (14.7%). FBXW7 gene mutations were detected in 9 cases (14.8%, 9/61), of which 5 cases had both NOTCH1 and FBXW7 gene mutations. Twenty-three (37.7%, 23/61) cases were wild type. The median white blood cell count of patients in NOTCH1/FBXW7 gene mutations group and wild-type group was 76.4×109/L (8.3×109/L, 149.2×109/L), 54.1×109/L (5.3×109/L, 156.6×109/L), respectively. Moreover, the hemoglobin was (89.1±27.1) g/L and (99.5±23.1) g/L, respectively, and the median proportion of bone marrow primordial cells was 84.5% (69.0%, 91.3%) and 60.0%(35.0%, 80.0%), respectively. The gene expression rate of SIL-TAL1, Hox11 and Hox11L2 was 7.9% (3/38) vs 17.4% (4/23), 18.4% (7/38) vs 4.3% (1/23), 5.3% (2/38) vs 13.0% (3/23), respectively (all P>0.05). However, the median platelet level in the NOTCH1/FBXW7 gene mutations group was 60.5×109/L (36.8×109/L, 100.3×109/L), which was lower than that in the wild-type group [116.0×109/L (63.0×109/L, 178.0×109/L)] (P=0.018). The median number of gene mutations in the group with NOTCH1/FBXW7 gene mutations group was 2.5 (1.8, 4.0), which was more than that in the group without NOTCH1/FBXW7 gene mutations group [0 (0, 1.0)] (P<0.001). The median EFS and OS of adult NOTCH1/FBXW7 gene mutations group were 28.0 (95%CI: 7.3-48.7) months and 30.0 (95%CI: 8.9-51.1) months, respectively, which were better than those of adult wild-type group [4.5 (95%CI: 0-11.6) months and 9.0 (95%CI: 0-19.1) months] (P=0.008 and 0.014).The median EFS and OS of children NOTCH1/FBXW7 gene mutations group were 12.0 (95%CI: 10.4-13.6) months and 19.0 (95%CI: 13.6-24.4) months, respectively, and those of wild-type group were 10.0 (95%CI: 8.9-11.1) months and 21.0 (95%CI: 0-51.4) months, respectively (P=0.673 and 0.434). Conclusions: The mutation rate of NOTCH1/FBXW7 gene is higher in T-ALL patients. Patients with NOTCH1/FBXW7 gene mutations group have lower platelet count and better EFS and OS. NOTCH1/FBXW7 gene mutation may be used as a hierarchical basis for individualized treatment of adult T-ALL patients.

[Analysis of clinical features and prognosis of patients with chronic myelogenous leukemia harboring additional chromosomal abnormalities in Ph-positive cells].

Objective: To investigate the effects of additional chromosomal abnormalities (ACA) in Philadelphia chromosome-positive (Ph(+)) cells on biological characteristics, therapy efficacy, and prognosis of patients with primary chronic myeloid leukemia (CML) -chronic phase (CP) and those who developed CML-accelerated phase/blast phase (AP/BP) during therapy. Methods: The clinical data of 410 patients with Ph(+) CML, including 348 patients with primary CML-CP and 62 patients who progressed to CML-AP/BP during treatment, who were admitted to Henan People's Hospital from January 2013 to June 2020 were retrospectively analyzed to categorize into high-risk, non-high-risk, and non-ACA groups according to the ELN2020 criteria. The effects of high- and non-high-risk ACA on biological characteristics, therapy efficacy, and prognosis were compared. Results: ①Among the 348 patients with primary CML-CP, 20 patients (5.75% ) had ACA, including 3 and 17 patients with high-risk and non-high-risk ACA, respectively, whereas the remaining 328 patients did not have ACA. There were no significant differences in baseline clinical characteristics between those with and without ACA (P>0.05 for all) . The rates of complete hematological response, complete cytogenetic response, major molecular remission, and 5-year overall survival (OS) were not significantly different between the non-high-risk ACA and non-ACA groups (P>0.05 for all) ; however, the 5-year progression-free survival of the non-high-risk ACA group (42.0% ) was significantly lower than that of the non-ACA group (74.5% ) (χ(2)=4.766, P=0.029) .②Of the 62 patients who progressed to CML-AP/BP during treatment, 41 patients (66.13% ) had ACA, including 28 and 13 patients with high-risk and non-high-risk ACA, respectively, whereas the remaining 21 patients did not have ACA. Platelet counts of the high-risk ACA group (42.5×10(9)/L) were lower than those of the non-high-risk (141×10(9)/L) and non-ACA groups (109×10(9)/L) (χ(2)=4.968, P=0.083) . There was no significant difference in the incidence of point mutations in ABL kinase among the three groups (P=0.652) . The complete cytogenetic response of the high-risk ACA group (5.3% ) was significantly lower than that of the non-ACA group (46.7% ) (χ(2)=5.851, P=0.016) . The 5-year OS of the high-risk ACA group was lower than that of the non-ACA group (46.2% vs 77.8% , χ(2)=3.878, P=0.049) . Subgroup analysis revealed that the 5-year OS rate of the high-risk group Ⅱ, which included -7/7q-, i (17q) , and complex karyotype comprising ≥2 high-risk ACA, was significantly lower than that of the non-ACA group (28.6% vs 77.8% , χ(2)=8.035, P=0.005) whereas the 5-year OS rate was not significantly different between high-risk group Ⅰ, which included +8,+Ph, and complex ACA with +8/+Ph, and the non-ACA group (54.5% vs 77.8% , χ(2) =1.514, P=0.219) . Conclusion: Due to different disease stages and ACA/Ph(+) types, treatment response and prognosis vary among patients with CML harboring ACA/Ph(+). The emergence of high-risk ACA during therapy suggests worse therapy efficacy and prognosis. Strict and standardized cytogenetic monitoring is critical for early detection, precise diagnosis, and treatment of these patients.

[Effect of triple-induction regimen including all-trans retinoic acid, arsenic trioxide plus anthracyclines for adults with non-high-risk acute promyelocytic leukemia].

Objective: To analyze the effect of triple-induction regimen including all-trans retinoic acid(ATRA), arsenic trioxide(ATO) plus anthracyclines and double-induction regimen including ATRA and ATO for adults with non-high-risk acute promyelocytic leukemia(APL). Methods: The clinical data of adult patients with non-high-risk APL who were first diagnosed and admitted to the Henan Provincial People's Hospital from January 2009 to December 2019 were retrospectively analyzed. All patients were divided into triple-induction group and double-induction group according to the treatment. The general data of patients, blood routine, coagulation function changes and blood transfusions during the induction period were collected, and the complete remission rate, early mortality and prognosis of two groups were analyzed. Results: A total of 164 patients were enrolled, including 86 males and 78 females, and the M(Q1,Q3) of their age was 41(18, 70) years. Among them, 75 were in triple-induction group and 89 in double-induction group. The white blood cell(WBC) counts of triple-induction group on day 7th and 14th after induction were (9.49±6.10)×109/L and (5.43±3.97)×109/L, while those in double-induction group were (15.17±17.06)×109/L and (13.37±12.59)×109/L, the differences were statistically significant (both P<0.05). In addition, the peak of WBC in the triple-induction group was lower than that in the double-induction group [13.8(6.3,89.7)×109/L vs 19.2(3.8,112.8)×109/L, P=0.019]. On day 7th after induction, the platelet(PLT) counts in the triple-induction group was lower than that in the double-induction group [27(11,147)×109/L vs 45(8, 183)×109/L, P=0.014]. However, the difference was not statistically significant in PLT counts between the two groups on day 14th, 21st and 28th, or in PLT transfusions during induction (all P>0.05). After treatment, it was observed only in a few patients of two groups that the prothrombin time(PT) elongation ≥3 s and/or activated partial thromboplastin time(APTT) elongation ≥10 s, and the difference was not statistically significant (all P>0.05). The incidence of induced differentiation syndrome in the triple-induction group was lower than that in the double-induction group (2.7% vs 12.4%, P=0.022) The early mortality rate was lower than that in the double-induction group (1.3% vs 5.6%), but the difference was not statistically significant (P>0.05). There were no statistically significant differences in the early complete remission rate, genetic remission rate, molecular remission rate, relapse rate, overall survival (OS) rate and disease-free survival (DFS) rate between the two groups. Conclusion: For adults with non-high-risk APL, the triple-induction therapy can reduce the counts and peaks of WBC, and reduce the incidence of induced differentiation syndrome.

Long-term survival outcomes of brentuximab vedotin in patients with relapsed or refractory Hodgkin lymphoma: a systematic review and meta-analysis.

OBJECTIVE: The short-term benefits of brentuximab vedotin (BV) for classical Hodgkin lymphoma (cHL) are well established, but its long-term benefits for refractory/relapsing (r/r) cHL are unknown. A meta-analysis was undertaken to examine the overall survival (OS), and progression-free survival (PFS) from relevant studies with patients with r/r cHL post-autologous stem cell transplantation (ASCT) exposed to BV. MATERIALS AND METHODS: PubMed, Embase, and the Cochrane library were searched for available papers published up to January 2020. The main outcomes included 3-year OS/PFS and/or 5-year OS/PFS. Data were pooled using random-effects models. RESULTS: Four studies were included: one randomized controlled trial, one single-arm trial, and two retrospective studies. The four studies included a total of 383 patients (mean of 95.75/study). The proportion of females was 21%-89%. The median age was 26-33 years. The 3-year OS was available for one study and was 41% in patients with r/r cHL with BV after ASCT (OR=0.41, 95% CI: 0.16-0.67). The 5-year OS was available for two studies and was 34% in patients with r/r cHL with BV after ASCT (OR=0.34, 95% CI: 0.19-0.48; mixed-effects model). The 5-year PFS was available for three studies and was 31% in patients with r/r cHL with BV after ASCT (OR=0.31, 95% CI: 0.02-0.61; mixed-effects model). CONCLUSIONS: The 5-year OS in patients with r/r cHL treated with BV after ASCT is 34% (95 CI: 19%-48%). The 5-year PFS in patients with r/r cHL treated with BV after ASCT is 31% (95 CI: 2%-61%).

[Efficacy and safety of PD-1 inhibitor combined with chemotherapy in the primary treatment of phase â ¢/â £ extranodal nasal-type natural killer/T cell lymphoma].

The data of 9 patients with stage Ⅲ/Ⅳ extranodal nasal-type natural killer/T cell lymphoma from August 2019 to August 2020 in People's Hospital of Zhengzhou University was retrospectively analyzed. All the patients were treated with the programmed cell death-1 (PD-1) inhibitor combined with P-GemoX-DEX (gemcitabine+oxaliplatin+dexamethasone+peraspartase) regimen as the first-line treatment. After 4 cycles of treatment, positron emission tomography/computed tomography (PET/CT) was used to evaluate the curative effect, and adverse reactions were also observed. The median follow-up time was 7 months. The overall response rate, complete and partial remission rate was 9/9, 6/9 and 3/9, respectively. The main adverse event was hematological toxicity, with 6 cases of grade Ⅰ/Ⅱ neutropenia, and no immune-related adverse events were reported.
