ABSTRACT

Objective: To summarize the therapeutic effects of Chinese Children Leukemia Group-acute lymphoblastic leukemia (CCLG-ALL) 2018 regimen in children with T cell acute lymphoblastic leukemia (T-ALL) and to find out risk indicators for prognosis. Methods: This study was a prospective multicenter cohort study involving 299 newly diagnosed T-ALL children in 21 Grade A tertiary hospitals nationwide. All patients received CCLG-ALL 2018 regimen and clinical data for treatment efficacy evaluating was collected. Variables associated with event free survival (EFS) rate, overall survival (OS) rate and cumulative recurrence rate were evaluated by Lasso regression analysis (including variables selection, model construction and hazard ratio calculating). Results: A total of 299 newly diagnosed T-ALL children were included, accounting for 9.9% (299/3 026) of all ALL patients. Among these patients, there were 224 males and 75 females, and the age of onset was 7.0 (4.7, 10.6) years. All patients received CCLG-ALL 2018 regimen treatment. After 31.1 (17.3, 43.8) months follow-up, 3-year EFS, 3-year OS and cumulative recurrence rate of them were (83.2±2.7)%, (91.3±1.8)%, and (7.9±1.7)%, respectively. Minimal residual disease (MRD) greater than 10.00% on day 15 of induction therapy was a risk factor for EFS (HR=1.89, 95%CI 1.04-3.44), OS (HR=2.82, 95%CI 1.35-5.92), and cumulative recurrence rate (HR=3.05, 95%CI 1.46-6.34). Compared with the medium-risk group, the high-risk group had higher induction failure rate (5.2% (7/134) vs. 0 (0/145), P=0.016) and lower complete remission rate (88.8% (119/134) vs.97.9% (142/145),P=0.004). Most complications happened during induction therapy (95 cases), and the most common complication was serious infection (158 cases). Conclusions: CCLG-ALL 2018 regimen shows good prognosis. MRD greater than 10.00% on day 15 of induction therapy is a strong risk factor, which can indicate the prognosis in the early stage of the disease and guide the appropriate treatment.

ABSTRACT

Cyclin-dependent kinase 4/6 (CDK4/6) inhibitors have led transformative breakthrough of clinical therapy for hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER-2)-negative breast cancer patients. CDK4/6 inhibitors that have been marketed in China include Ribociclib, Palbociclib, Abemaciclib and Dalpiciclib. For HR-positive HER-2-negative locally advanced and metastatic breast cancer, CDK4/6 inhibitors combined with endocrine therapy have become standard regimen, which can prolong the survival of patients. In the adjuvant treatment stage of early breast cancer, CDK4/6 inhibitors have also achieved positive results and been approved for indications. At present, CDK4/6 inhibitors have been widely used in clinical practice in China. In order to further improve the standardized application of CDK4/6 inhibitors in China, the Breast Cancer Expert Committee of the National Center for Cancer Quality Control and the Professional Committee of Clinical Research of Cancer Drugs of the Chinese Anti-Cancer Association organized the related expert to update the consensus based on the "CDK4/6 inhibitor consensus on clinical application of in the treatment of hormone receptor positive human epidermal growth factor receptor 2 negative advanced breast cancer (2021 edition)" . The updated consensus systematically introduces the pharmacological characteristics, drug monitoring and adverse event management, etc., of CDK4/6 inhibitors to promote the accuracy of clinical decision-making with the ultimate goal to prolong the overall survival of patients and improve the quality of life.

ABSTRACT

Stage Ⅱ (T3-4N0M0) accounts for 25% of colorectal cancer and five-year survival is between 70% and 80%. However, 25% of patients develop distant metastases and have a survival rate similar to that of stage Ⅲ disease. However, whether or not to give adjuvant chemotherapy is still a controversial issue. As a result, there has been a lot of interest in the identification of the pathological factors underlying the poor prognosis associated with this stage, in order to establish a firmer basis for the administration of adjuvant chemotherapy. But not all high-risk factors are equal for stage Ⅱ colorectal cancer, variability still exists in the management and outcomes of high-risk patients. Here be introduced and commented on thinking and understanding about its controversy and evolution for the attention of the working pathologist and gastroenterologist doctors.

ABSTRACT

Objective: To investigate the clinical characteristics, cytogenetics, molecular biology, treatment, and prognosis of patients with therapy-related myelodysplastic syndrome and acute myeloid leukemia (t-MDS/AML) secondary to malignancies. Methods: The clinical data of 86 patients with t-MDS/AML in West China Hospital of Sichuan University between January 2010 and April 2023 were retrospectively analyzed. The clinical characteristics, primary tumor types, and tumor-related therapies were analyzed. Results: The study enrolled a total of 86 patients with t-MDS/AML, including 67 patients with t-AML, including 1 patient with M(0), 6 with M(1), 27 with M(2), 9 with M(3), 12 with M(4), 10 with M(5), 1 with M(6), and 1 with M(7). Sixty-two patients could be genetically stratified, with a median overall survival (OS) of 36 (95% CI 22-52) months for 20 (29.9%) patients in the low-risk group and 6 (95% CI 3-9) months for 10 (14.9%) in the intermediate-risk group. The median OS time was 8 (95% CI 1-15) months in 32 (47.8%) patients in the high-risk group. For patients with non-acute promyelocytic leukemia (APL) and AML, the median OS of the low-risk group was 27 (95% CI 18-36) months, which was significantly longer than that of the non-low-risk group (χ(2)=5.534, P=0.019). All 9 APL cases were treated according to the initial treatment, and the median OS was not reached, and the 1-, 2-, and 3-year OS rates were 100.0%, (75.0±6.2) %, and (75.0±6.2) % respectively. Of the 58 patients with non-APL t-AML (89.7%), 52 received chemotherapy, and 16 achieved complete remission (30.8%) after the first induction chemotherapy. The 1-, 2-, and 3-year OS rates of the non-APL t-AML group were (42.0 ± 6.6) %, (22.9±5.7) %, and (13.4±4.7) %, respectively. The median OS of patients who achieved remission was 24 (95% CI 18-30) months, and the median OS of those who did not achieve remission was 6 (95% CI 3-9) months (χ(2)=10.170, P=0.001). Bone marrow CR was achieved in 7 (53.8%) of 13 patients treated with vineclar-containing chemotherapy, with a median OS of 12 (95% CI 9-15) months, which was not significantly different from that of vineclar-containing chemotherapy (χ(2)=0.600, P=0.437). In 19 patients with t-MDS, the 1-, 2-, and 3-year OS rates were (46.8±11.6) %, (17.5±9.1) %, and (11.7±9.1) % with a median OS of 12 (95% CI 7-17) months, which was not significantly different from that in t-AML (χ(2)=0.232, P=0.630) . Conclusions: Breast cancer, bowel cancer, and other primary tumors are common in patients with t-MDS/AML, which have a higher risk of adverse genetics. Patients with APL had a high induction remission rate and a good long-term prognosis, whereas patients without APL had a low remission rate and a poor long-term prognosis.

ABSTRACT

Objective: To evaluate the efficacy and safety of bendamustine combined with pomalidomide and dexamethasone (BPD regimen) in the treatment of relapsed multiple myeloma (MM) with extramedullary disease. Methods: This open, single-arm, multicenter prospective cohort study included 30 relapsed MM patients with extramedullary disease diagnosed in seven hospitals including Qingdao Municipal Hospital. The patients were treated with BPD regimen from February 2021 to November 2022. This study analyzed the efficacy and adverse reactions of the BPD regimen. Results: The median age of the 30 patients was 62 (47-72) years, of which 18 (60% ) had first-time recurrence. The overall response rate (ORR) of the 18 patients with first-time recurrence was 100%, of which three (16.7% ) achieved complete remission, 10 (55.5% ) achieved very good partial remission (VGPR), and five (27.8% ) achieved partial remission (PR). The ORR of 12 patients with recurrence after second-line or above treatment was 50%, including zero patients with ≥VGPR and six patients (50% ) with PR. Three cases (25% ) had stable disease, and three cases (25% ) had disease progression. The one-year progression free survival rate of all patients was 65.2% (95% CI 37.2% -83.1% ), and the 1-year overall survival rate was 90.0% (95% CI 76.2% -95.4% ). The common grade 3-4 hematology adverse reactions included two cases (6.7% ) of neutropenia and one case (3.3% ) of thrombocytopenia. The overall adverse reactions are controllable. Conclusions: The BPD regimen has good efficacy and tolerance in relapsed MM patients with extramedullary disease.

ABSTRACT

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

ABSTRACT

Objective:To evaluate the clinical significance of neoadjuvant immunotherapy combined with chemotherapy in the treatment of larynx preservation in locally advanced hypopharyngeal squamous cell carcinoma. Methods:Patients with locally advanced HPSCC(cT3-T4aN0-N3M0) were eligible. All received 2 cycles of pembrolizumab combined with docetaxel and platinum neoadjuvant induction therapy. After two cycles, the efficacy was evaluated, followed by radical chemoradiotherapy or surgery and adjuvant chemoradiotherapy according to the efficacy. The primary endpoints were objective response rate(ORR) ,larynx-preservation(LP) rate at 3 months post-treatment and the adverse reactions during neoadjuvant therapy. Results:From December 2021 to December 2022, 10 patients with locally advanced HPSCC(cT3-T4aN0-N3M0) were enrolled. After 2 cycles of the neoadjuvant therapy, 2 patients achieved complete response(CR), 7 patients achieved partial response(PR), 1 patient was stable disease(SD), objective response rate(ORR) was 90%, and disease control rate(DCR) was 100%. 5 patients received radical chemoradiotherapy, 5 patients received surgery and adjuvant chemoradiotherapy, four of them received partial laryngectomy and partial hypopharyngeal resection surgery, and one of them received total laryngectomy and partial hypopharyngeal resection surgery. All patients were able to withstand adverse reactions of neoadjuvant therapy and successfully completed the whole treatment of HPSCC without grade 3-4 treatment-related adverse reactions. There was no recurrence or metastasis during 3-18 months of follow-up. 1 patient died of severe pneumonia 3 months after the completion of radical chemoradiotherapy. At 3 months after treatment, the larynx-preservation rate was 80%. Conclusion:Neoadjuvant immunotherapy combined with chemotherapy has good short-term efficacy and the adverse reactions were tolerable. It can improve the larynx-preservation rate of patients with locally advanced HPSCC, thus improving the prognosis and quality of life of patients.

ABSTRACT

Composite lymphoma (CL) involving B-cell lymphoma and T-cell lymphoma is extremely rare. Herein, we report three such cases using immunohistochemistry, flow cytometry, and the next-generation sequencing (NGS) to identify the pathological and molecular characteristics of CL. In the first case, the patient was admitted to hospital for generalized pruritic maculopapular rash over the whole body. An excisional biopsy of the skin lesions showed T-cell lymphoma. At the same time, the staging bone marrow (BM) biopsy revealed a diffuse large B-cell lymphoma (DLBCL). After R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) therapies, the patient produced a good response with substantial dissipation of the rashes and relief of skin. The other two patients were admitted to hospital due to lymphadenopathy and were diagnosed with DLBCL and follicular lymphoma (FL) after core needle biopsy of lymph nodes, BM biopsy, BM aspiration, and flow cytometry. Following R-CHOP and R-COP (rituximab, cyclophosphamide, vincristine, and prednisone) therapies, they achieved complete remission unconfirmed (CRu) and complete remission (CR). However, one or two years later, they suffered a relapse of lymphadenopathy. The shocking fact was that re-biopsy of lymphadenopathy revealed peripheral T-cell lymphoma (PTCL) and angioimmunoblastic T-cell lymphoma (AITL). NGS findings identified DNA methyltransferase 3a (DNMT3a), isocitrate dehydrogenase 2 (IDH2), Ras homolog gene family, member A (RHOA), splicing factor 3B subunit 1 (SF3B1), and tumor protein p53 (TP53) mutations. After immunochemotherapy, these patients achieved CRu and CR again. Nevertheless, they suffered a second relapse of T-cell lymphoma. Finally, they died due to progression of disease. We found that the occurrence of CL is associated with Epstein-Barr virus infection and DNMT3a, IDH2, and TP53 mutations, and the prognosis of the disease is closely related to the T-cell lymphoma components.

ABSTRACT

BACKGROUND@#Exploring the underlying mechanism of rituximab resistance is critical to improve the outcomes of patients with diffuse large B-cell lymphoma (DLBCL). Here, we tried to identify the effects of the axon guidance factor semaphorin-3F (SEMA3F) on rituximab resistance as well as its therapeutic value in DLBCL.@*METHODS@#The effects of SEMA3F on the treatment response to rituximab were investigated by gain- or loss-of-function experiments. The role of the Hippo pathway in SEMA3F-mediated activity was explored. A xenograft mouse model generated by SEMA3F knockdown in cells was used to evaluate rituximab sensitivity and combined therapeutic effects. The prognostic value of SEMA3F and TAZ (WW domain-containing transcription regulator protein 1) was examined in the Gene Expression Omnibus (GEO) database and human DLBCL specimens.@*RESULTS@#We found that loss of SEMA3F was related to a poor prognosis in patients who received rituximab-based immunochemotherapy instead of chemotherapy regimen. Knockdown of SEMA3F significantly repressed the expression of CD20 and reduced the proapoptotic activity and complement-dependent cytotoxicity (CDC) activity induced by rituximab. We further demonstrated that the Hippo pathway was involved in the SEMA3F-mediated regulation of CD20. Knockdown of SEMA3F expression induced the nuclear accumulation of TAZ and inhibited CD20 transcriptional levels via direct binding of the transcription factor TEAD2 and the CD20 promoter. Moreover, in patients with DLBCL, SEMA3F expression was negatively correlated with TAZ, and patients with SEMA3F low TAZ high had a limited benefit from a rituximab-based strategy. Specifically, treatment of DLBCL cells with rituximab and a YAP/TAZ inhibitor showed promising therapeutic effects in vitro and in vivo .@*CONCLUSION@#Our study thus defined a previously unknown mechanism of SEMA3F-mediated rituximab resistance through TAZ activation in DLBCL and identified potential therapeutic targets in patients.

ABSTRACT

BACKGROUND@#Endocrine therapy (ET) and ET-based regimens are the preferred first-line treatment options for hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer (HR+/HER2- MBC), while chemotherapy (CT) is commonly used in clinical practice. The aim of this study was to investigate the efficacy and clinical outcome of ET and CT as first-line treatment in Chinese patients with HR+/HER2- MBC.@*METHODS@#Patients diagnosed with HR+/HER2-MBC between January 1st, 1996 and September 30th, 2018 were screened from the Chinese Society of Clinical Oncology Breast Cancer database. The initial and maintenance first-line treatment, progression-free survival (PFS), and overall survival (OS) were analyzed.@*RESULTS@#Among the 1877 included patients, 1215 (64.7%) received CT and 662 (35.3%) received ET as initial first-line treatment. There were no statistically significant differences in PFS and OS between patients receiving ET and CT as initial first-line treatment in the total population (PFS: 12.0 vs. 11.0 months, P = 0.22; OS: 54.0 vs . 49.0 months, P =0.09) and propensity score matched population. For patients without disease progression after at least 3 months of initial therapy, maintenance ET following initial CT (CT-ET cohort, n = 449) and continuous schedule of ET (ET cohort, n = 527) had longer PFS than continuous schedule of CT (CT cohort, n = 406) in the total population (CT-ET cohort vs. CT cohort: 17.0 vs . 8.5 months; P <0.01; ET cohort vs . CT cohort: 14.0 vs . 8.5 months; P <0.01) and propensity score matched population. OS in the three cohorts yielded the same results as PFS.@*CONCLUSIONS@#ET was associated with similar clinical outcome to CT as initial first-line treatment. For patients without disease progression after initial CT, switching to maintenance ET showed superiority in clinical outcome over continuous schedule of CT.

ABSTRACT

BACKGROUND@#The effect of intra-operative chemotherapy (IOC) on the long-term survival of patients with colorectal cancer (CRC) remains unclear. In this study, we evaluated the independent effect of intra-operative infusion of 5-fluorouracil in combination with calcium folinate on the survival of CRC patients following radical resection.@*METHODS@#1820 patients were recruited, and 1263 received IOC and 557 did not. Clinical and demographic data were collected, including overall survival (OS), clinicopathological features, and treatment strategies. Risk factors for IOC-related deaths were identified using multivariate Cox proportional hazards models. A regression model was developed to analyze the independent effects of IOC.@*RESULTS@#Proportional hazard regression analysis showed that IOC (hazard ratio [HR]=0.53, 95% confidence intervals [CI] [0.43, 0.65], P  < 0.001) was a protective factor for the survival of patients. The mean overall survival time in IOC group was 82.50 (95% CI [80.52, 84.49]) months, and 71.21 (95% CI [67.92, 74.50]) months in non-IOC group. The OS in IOC-treated patients were significantly higher than non-IOC-treated patients ( P  < 0.001, log-rank test). Further analysis revealed that IOC decreased the risk of death in patients with CRC in a non-adjusted model (HR=0.53, 95% CI [0.43, 0.65], P  < 0.001), model 2 (adjusted for age and gender, HR=0.52, 95% CI [0.43, 0.64], P  < 0.001), and model 3 (adjusted for all factors, 95% CI 0.71 [0.55, 0.90], P  = 0.006). The subgroup analysis showed that the HR for the effect of IOC on survival was lower in patients with stage II (HR = 0.46, 95% CI [0.31, 0.67]) or III disease (HR=0.59, 95% CI [0.45, 0.76]), regardless of pre-operative radiotherapy (HR=0.55, 95% CI [0.45, 0.68]) or pre-operative chemotherapy (HR=0.54, 95% CI [0.44, 0.66]).@*CONCLUSIONS@#IOC is an independent factor that influences the survival of CRC patients. It improved the OS of patients with stages II and III CRC after radical surgery.@*TRIAL REGISTRATION@#chictr.org.cn, ChiCTR 2100043775.

ABSTRACT

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

ABSTRACT

Peritoneal tumours have a large population and a poor prognosis with limited therapeutic options available, and are common originated from gastric, colorectal, appendix and other cancers. Traditionally, peritoneal tumours have long been considered to be a terminal condition with a median survival of 3-6 months, and the palliative symptomatic treatment is recommended. Recently, the multimodal therapeutic strategy of cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) has resulted in more effective on the prevention and treatment of peritoneal metastasis, which can significantly improve the survival and quality of life. Under the guidance of the China Anti-Cancer Association (CACA), the "CACA Guidelines for Holistic Integrative Management of Cancer-Peritoneal Tumours" was jointly completed by experts in related fields organized by the Chinese Society of Peritoneal Oncology. This guideline is guided by the concept of integrative medicine and focuses on the domestic epidemiology, genetic background and original studies. It emphasizes the multidisciplinary team to holistic integrative medicine (MDT to HIM), and pays attention to the whole-course management of "prevention, screening, diagnosis, treatment, and rehabilitation". This guideline mainly focuses on peritoneal metastasis from gastrointestinal tumours, aiming to standardize the clinical diagnosis and treatment process, and jointly promote the management of peritoneal metastasis in China.

ABSTRACT

Non-Hodgkin lymphoma (NHL) is a common lymphoid hematological malignancy, the treatment and prognosis of NHL have always been the focus of clinical attention. Chemotherapy is the main first-line treatment, but there is still no effective treatment for patients with poor response to chemotherapy, recurrence or progression within a short period of time after treatment, and new and effective drugs need to be developed clinically. As the only clinically validated oral selective inhibitor of nuclear export (SINE), Selinexor has been approved for the treatment of relapsed/refractory diffuse large B-cell lymphoma and multiple myeloma, clinical attempts are being made to apply it to the treatment of other hematological malignancies.This article reviews the anti-tumor mechanism of Selinexor and the latest research progress in its application in NHL, and provides ideas for a more diverse, standardized and effective applications of Selinexor in NHL.

ABSTRACT

OBJECTIVE@#To investigate the efficacy and safety of daratumumab in treatment of multiple myeloma (MM) patients with renal impairment (RI).@*METHODS@#The clinical data of 15 MM patients with RI who received daratumumab-based regimen from January 2021 to March 2022 in three centers were retrospectively analyzed. Patients were treated with daratumumab or daratumumab combined with dexamethasone or daratumumab combined with bortezomib and dexamethasone and the curative effect and survival were analyzed.@*RESULTS@#The median age of 15 patients was 64 (ranged 54-82) years old. Six patients were IgG-MM, 2 were IgA-MM,1 was IgD-MM and 6 were light chain MM. Median estinated glomerular filtration rate (eGFR) was 22.48 ml/(min·1.73 M2). Overall response rate of 11 patients with MM was 91% (≥MR), including 1 case of stringent complete response (sCR), 2 cases of very good partial response (VGPR), 3 cases of partial response (PR) and 4 cases of minor response (MR). The rate of renal response was 60%(9/15), including 4 cases of complete response (CR), 1 case of PR and 4 cases of MR. A median time of optimal renal response was 21 (ranged 7-56) days. With a median follow-up of 3 months, the median progression-free survival and overall survival of all patients were not reached. After treatment with daratumumab-based regimen, grade 1-2 neutropenia was the most common hematological adverse reaction. Non-hematological adverse reactions were mainly infusion-related adverse reactions and infections.@*CONCLUSION@#Daratumumab-based regimens have good short-term efficacy and safety in the treatment of multiple myeloma patients with renal impairment.

ABSTRACT

OBJECTIVE@#To explore the treatment of children with high-risk acute promyelocytic leukemia (APL), aiming to improve the prognosis.@*METHODS@#The clinical datas of 24 children with high-risk APL in our hospital from January 2015 to June 2021 were retrospectively analyzed.@*RESULTS@#The main manifestations of 24 children (including 15 males and 9 females) were purpura, gingiva bleeding and nasal hemorrhage, with a median age of 7 years old and a median leukocyte count of 28.98 (10-232)×109/L, including 15 cases with leukocyte count between 10×109/L and 50×109/L, 2 cases between 50×109/L and 100×109/L, and 7 cases >100×109/L. The leukocyte count of 2 cases in 3 children admitted from 2015 to November 2016 was >100×109/L, in which 1 case was first treated with homoharringtonine for cytoreduction, 7 days later treated with all-trans retinoic acid (ATRA) after genetic diagnosis, then died of differentiation syndrome and pulmonary hemorrhage after 3 days. The other one was treated with reduced ATRA+daunorubicin+arsenic trioxide (ATO) for induction, then achieved complete remission. The third one with leukocyte count 12×109/L had cerebral hemorrhage before admission and died on the 7th day of treatment. The remaining 21 children were treated with chemotherapy according to the APL regimen for children in South China, including 14 cases with leukocyte count between 10×109/L and 50×109/L, 2 cases between 50×109/L and 100×109/L, and 5 cases >100×109/L. In the 5 children with leukocyte count >100×109/L, 1 case died of cerebral hemorrhage on the second day of oral ATRA before the addition of anthracyclines, 3 cases died of cerebral hemorrhage after the addition of anthracyclines to chemotherapy on the second day of oral ATRA, and another one developed differentiation syndrome after the addition of mitoxantrone on the second day of oral ATRA, then achieved complete remission after ATRA reduction chemotherapy and survived without disease till now. In the 2 children with leukocyte count between 50×109/L and 100×109/L, 1 case died of cerebral hemorrhage on the second day of oral ATRA before the addition of anthracyclines. All the children were followed up until 1st August, 2021, with a median follow-up time of 40 months, including 7 deaths and 1 recurrence in maintenance therapy who achieved second remission after chemotherapy, 14 cases survived in 3 years and 13 cases survived without event. The 7 dead children had a median time from treatment to death of 5 days, including 1 case with leukocyte count between 10×109/L and 50×109/L, 1 case between 50×109/L and 100×109/L, and 5 cases >100×109/L.@*CONCLUSION@#High-risk APL children with leukocyte count >100×109/L have a high mortality rate. Gradual addition of chemotherapy starting at small doses and early addition of ATO may help to improve the prognosis.

ABSTRACT

OBJECTIVES@#To study the efficacy and safety of rituximab combined with chemotherapy in the treatment of children and adolescents with mature B-cell non-Hodgkin's lymphoma (B-NHL) through a Meta analysis.@*METHODS@#The databases including PubMed, Embase, the Cochrane Library, ClinicalTrials.gov, Web of Science, China National Knowledge Infrastructure, Wanfang Data, and Weipu were searched to obtain 10 articles on rituximab in the treatment of mature B-NHL in children and adolescents published up to June 2022, with 886 children in total. With 3-year event-free survival (EFS) rate, 3-year overall survival (OS) rate, complete remission rate, mortality rate, and incidence rate of adverse reactions as outcome measures, RevMan 5.4 software was used for Meta analysis, subgroup analysis, sensitivity analysis, and publication bias analysis.@*RESULTS@#The rituximab+chemotherapy group showed significant increases in the 3-year EFS rate (HR=0.38, 95%CI: 0.25-0.59, P<0.001), 3-year OS rate (HR=0.29, 95%CI: 0.14-0.61, P=0.001), and complete remission rate (OR=3.72, 95%CI: 1.89-7.33, P<0.001) as well as a significant reduction in the mortality rate (OR=0.31, 95%CI: 0.17-0.57, P<0.001), as compared with the chemotherapy group without rituximab. There was no significant difference in the incidence rate of adverse reactions between the two groups (OR=1.28, 95%CI: 0.85-1.92, P=0.24).@*CONCLUSIONS@#The addition of rituximab to the treatment regimen for children and adolescents with mature B-cell non-Hodgkin's lymphoma can bring significant survival benefits without increasing the incidence of adverse reactions.

ABSTRACT

BACKGROUND@#To compare the efficacy and safety of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin plus rituximab (DA-EPOCH-R) with standard rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in Waldeyer's ring diffuse large B-cell lymphoma (WR-DLBCL) at a single institution.@*METHODS@#This retrospective study included 115 newly diagnosed patients with WR-DLBCL, of whom 68 patients received R-CHOP, and 47 patients received DA-EPOCH-R as their first-line treatment. The baseline features of the two groups were well balanced using a 1:1 propensity score matching method, and a total of 84 cases were obtained, including respective 42 cases in the R-CHOP and DA-EPOCH-R groups, for further survival and prognosis analysis. The primary objectives included progression-free survival (PFS) and overall survival (OS).@*RESULTS@#During a median follow-up of 45 months, there were nine (21.4%) deaths in the R-CHOP group and two (4.8%) in the DA-EPOCH-R group. Kaplan-Meier analysis showed statistically significant improvements in PFS and OS in patients with DA-EPOCH-R compared with those treated with R-CHOP (log-rank test, P  = 0.025 and P  = 0.035, respectively). The 2-year PFS and OS rates in the DA-EPOCH-R group were 90.1% (95% confidence interval [CI]: 81.4-99.8%) and 95.2% (95% CI: 89.0-100.0%), respectively, and 80.5% (95% CI: 69.3-93.6%) and 90.5% (95% CI: 52.8-99.8%) in the R-CHOP group. Patients without B symptoms and elevated lactate dehydrogenase levels had a higher PFS in the DA-EPOCH-R group, with P values of 0.038 (hazard ratio [HR]: 0.11; 95% CI: 0.01-0.88) and 0.042 (HR: 0.19; 95% CI: 0.04-0.94), respectively. There were no statistically significant differences in clinical responses and treatment-related toxicities between the two groups.@*CONCLUSION@#Compared with patients received R-CHOP, those treated by DA-EPOCH-R had superior PFS, OS, and controlled toxicity in patients with WR-DLBCL.

ABSTRACT

Breast cancer is the most common malignant tumor of women, which seriously threatens women's health. Albumin-bound paclitaxel is the basic chemotherapy drug for breast cancer treatment. We can promote reasonable clinical medication and improve patients' quality of life by standardizing chemotherapy plans, rationally optimizing treatment strategy and managing adverse reactions of albumin-bound paclitaxel. In order to standardize the clinical application of albumin-bound paclitaxel in breast cancer, Chinese Medical Doctor Association Oncologist Branch Breast Cancer Group and International Medical Exchange Branch of China Anti-Cancer Association consulted guidelines and the latest evidence-based evidences and formulated Chinese expert consensus of albumin-bound paclitaxel in the treatment of breast cancer to provide reference for clinical diagnosis and treatment of breast cancer. The consensus mainly introduces the clinical application strategies and evidence-based evidences of albumin-bound paclitaxel in advanced therapy, neoadjuvant therapy and adjuvant therapy of breast cancer. Among them, the regimens containing albumin-bound paclitaxel are the better recommended regimens for preoperative neoadjuvant and advanced rescue therapy of breast cancer. However, there is little evidence in adjuvant therapy, so it is recommended to use albumin-bound paclitaxel cautiously. We also invited breast cancer clinical experts to vote on some controversial issues, including but not limited to the usage and dosage of albumin-bound paclitaxel, combined medication and management of peripheral neuropathy, and formed consensus recommendations for the reference of breast cancer clinical workers.

ABSTRACT

Objective: Retrospective analysis of the efficacy and influencing factors of bladder preservation integrated therapy for unresectable invasive bladder cancer confined to the pelvis was done, also including the bladder function preservation and adverse effects analysis. Methods: Sixty-nine patients with unresectable locally invasive bladder cancer who received radiotherapy-based combination therapy from March 1999 to December 2021 at our hospital were selected. Among them, 42 patients received concurrent chemoradiotherapy, 32 underwent neoadjuvant chemotherapyand 43 with transurethral resection of bladder tumors (TURBT) prior to radiotherapy. The late adverse effect of radiotherapy, preservation of bladder function, replase and metastasis and survival were followed-up. Cox proportional hazards models were applied for the multifactorial analysis. Results: The median age was 69 years. There were 63 cases (91.3%) of uroepithelial carcinoma, 64 of stage Ⅲ and 4 of stage Ⅳ. The median duration of follow-up was 76 months. There were 7 grade 2 late genito urinary toxicities, 2 grade 2 gastrointestinal toxicities, no grade 3 or higher adverse events occurred. All patients maintained normal bladder function, except for 8 cases who lost bladder function due to uncontrolled tumor in the bladder. Seventeen cases recurred locally. There were 11 cases in the concurrent chemoradiotherapy group with a local recurrence rate of 26.2% (11/42) and 6 cases in the non-concurrent chemoradiotherapy group with a local recurrence rate of 22.2% (6/27), and the difference in local recurrence rate between the two groups was not statistically significant (P=0.709). There were 23 cases of distant metastasis (including 2 cases of local recurrence with distant metastasis), including 10 cases in the concurrent chemoradiotherapy group with a distant metastasis rate of 23.8% (10/42) and 13 cases in the non-concurrent chemoradiotherapy group with a distant metastasis rate of 48.1% (13/27), and the distant metastasis rate in the non-concurrent chemoradiotherapy group was higher than that in the concurrent chemoradiotherapy group (P=0.036). The median 5-year overall survival (OS) time was 59 months and the OS rate was 47.8%. The 5-year progression-free survival (PFS) time was 20 months and the PFS rate was 34.4%. The 5-year OS rates of concurrent and non-concurrent chemoradiotherapy group were 62.9% and 27.6% (P<0.001), and 5-year PFS rates were 45.4% and 20.0%, respectively (P=0.022). The 5-year OS rates of with or without neoadjuvant chemotherapy were 78.4% and 30.1% (P=0.002), and the 5-year PFS rates were 49.1% and 25.1% (P=0.087), respectively. The 5-year OS rates with or without TURBT before radiotherapy were 45.5% and 51.9% (P=0.233) and the 5-year PFS rates were 30.8% and 39.9% (P=0.198), respectively. Multivariate Cox regression analysis results showed that the clinical stage (HR=0.422, 95% CI: 0.205-0.869) was independent prognostic factor for PFS of invasive bladder cancer. The multivariate analysis showed that clinical stages (HR=0.278, 95% CI: 0.114-0.678), concurrent chemoradiotherapy (HR=0.391, 95% CI: 0.165-0.930), neoadjuvant chemotherapy (HR=0.188, 95% CI: 0.058-0.611), and recurrences (HR=10.855, 95% CI: 3.655-32.638) were independent prognostic factors for OS of invasive bladder cancer. Conclusion: Unresectable localized invasive bladder cancer can achieve satisfactory long-term outcomes with bladder-preserving combination therapy based on radiotherapy, most patients can retain normal bladder function with acceptable late adverse effects and improved survival particularly evident in patients with early, concurrent chemoradiotherapy and neoadjuvant chemotherapy.
