Objective: To identify in what phases in the treatment of head and neck cancer do delays happen at a tertiary hospital and to determine the association between the length of treatment delays and the oncologic outcomes (disease-free survival and overall survival) for patients with head and neck cancer. : Methods Design: Retrospective Cohort Study Setting: Tertiary National University Hospital Participants: Sixty-eight (68) patients who had surgery and adjuvant radiotherapy for invasive head and neck cancer at the Philippine General Hospital during the 5-year period of January 2014 to December 2019 were included in the initial consideration. Only 15 had survival data and were thus eligible for inclusion in this study. Results: The median treatment package time for head and neck cancers in our institution was 27.6 weeks or 193 days. The treatment package time statistically correlated with both overall survival, F(1,13)=12.952, p <0.005, R2=0.499, and disease-free survival, F(1-13)=12.823, p <0.005, R2= 0.497. However, the independent effects of other predictors such as time interval between first consult to histopathologic diagnosis, diagnosis to surgery, and surgery to post-operative radiotherapy, showed no statistically significant association with overall survival and disease free survival. Conclusion All study patients experienced treatment delays from diagnosis to surgery, and surgery to adjuvant radiation therapy, and in their total treatment package time. The positive correlation among treatment package time, and disease-free and overall survival in this study must be further investigated in order to elucidate the true effect of delays across time intervals in the treatment of head and neck cancer in the Philippine General Hospital. Every effort should be made towards timely management of these patients.

Objective: To analyze the clinical characteristics and prognosis of primary and secondary pancreatic diffuse large B-cell lymphoma (DLBCL) . Methods: Clinical data of patients with pancreatic DLBCL admitted at Shanghai Rui Jin Hospital affiliated with Shanghai Jiao Tong University School of Medicine from April 2003 to June 2020 were analyzed. Gene mutation profiles were evaluated by targeted sequencing (55 lymphoma-related genes). Univariate and multivariate Cox regression models were used to evaluate the prognostic factors of overall survival (OS) and progression-free survival (PFS) . Results: Overall, 80 patients were included; 12 patients had primary pancreatic DLBCL (PPDLBCL), and 68 patients had secondary pancreatic DLBCL (SPDLBCL). Compared with those with PPDLBCL, patients with SPDLBCL had a higher number of affected extranodal sites (P<0.001) and had higher IPI scores (P=0.013). There was no significant difference in the OS (P=0.120) and PFS (P=0.067) between the two groups. Multivariate analysis indicated that IPI intermediate-high/high risk (P=0.025) and double expressor (DE) (P=0.017) were independent adverse prognostic factors of OS in patients with pancreatic DLBCL. IPI intermediate-high/high risk (P=0.021) was an independent adverse prognostic factor of PFS in patients with pancreatic DLBCL. Targeted sequencing of 29 patients showed that the mutation frequency of PIM1, SGK1, BTG2, FAS, MYC, and MYD88 in patients with pancreatic DLBCL were all >20%. PIM1 (P=0.006 for OS, P=0.032 for PFS) and MYD88 (P=0.001 for OS, P=0.017 for PFS) mutations were associated with poor OS and PFS in patients with SPDLBCL. Conclusion: There was no significant difference in the OS and PFS between patients with PPDLBCL and those with SPDLBCL. IPI intermediate-high/high risk and DE were adverse prognostic factors of pancreatic DLBCL. PIM1, SGK1, BTG2, FAS, MYC, and MYD88 were common mutations in pancreatic DLBCL. PIM1 and MYD88 mutations indicated worse prognosis.

Objective: To investigate the prognosis impact of adjuvant trastuzumab treatment on human epidermal growth factor receptor 2 (HER-2) positive early breast cancer patients. Methods: A retrospective study was conducted, HER-2-positive T1N0M0 stage breast cancer patients who underwent surgery in the Affiliated Tumor Hospital of Xinjiang Medical University from January 2010 to December 2019 were divided into treatment group and control group according to whether they were treated with trastuzumab or not. Propensity score matching (PSM) was used to balance the confounding bias caused by differences in baseline characteristics between the two groups. Cox proportional hazards model was used to analyze the risk factors affecting disease-free survival (DFS). The Kaplan-Meier method was used to estimate the 3- and 5-year DFS and overall survival (OS) rates of the two groups before and after PSM. Results: There were 291 patients with HER-2 positive T1N0M0 stage breast cancer, including 21 cases in T1a (7.2%), 61 cases in T1b (21.0%), and 209 cases in T1c (71.8%). Before PSM, there were 132 cases in the treatment group and 159 cases in the control group, the 5-year DFS rate was 88.5%, and the 5-year OS rate was 91.5%. After PSM, there were 103 cases in the treatment group and 103 cases in the control group, the 5-year DFS rate was 86.0%, and the 5-year OS rate was 88.5%. Before PSM, there were significant differences in tumor size, histological grade, vascular invasion, Ki-67 index, postoperative chemotherapy or not and radiotherapy between the treatment group and the control group (P<0.05). After PSM, there were no significant difference in clinicopathological features between the treatment group and the control group (P>0.05). Multivariate analysis showed that histological grade (HR=2.927, 95 CI: 1.476, 5.805; P=0.002), vascular invasion (HR=3.410, 95 CI: 1.170, 9.940; P=0.025), menstrual status (HR=3.692, 95 CI: 1.021, 13.344, P=0.046), and chemotherapy (HR=0.238, 95 CI: 0.079, 0.720; P=0.011) were independent factors affecting DFS. After PSM, the 5-year DFS rate of the treatment group was 89.2%, while that of the control group was 83.5%(P=0.237). The 5-year OS rate of the treatment group was 96.1%, while that of the control group was 84.7%(P=0.036). Conclusion: Postoperative targeted therapy with trastuzumab can reduce the risk of recurrence and metastasis in patients with HER-2-positive T1N0M0 stage breast cancer.

OBJECTIVE: To detect the relative expression of IGLL1 (immunoglobulin lambda-like polypeptide 1) mRNA in bone marrow of children with T-cell acute lymphoblastic leukemia (T-ALL), and analyze its correlation with the clinical characteristics and prognosis of the patients, so as to clarify the clinical significance of IGLL1 in pediatric T-ALL patients. METHODS: A total of 56 pediatric T-ALL patients hospitalized in Children's Hospital of Soochow University from June 2012 to December 2017 and treated with CCLG-ALL 2008 regimen were selected. Transcriptome sequencing technology was used to detect the transcription level of IGLL1 gene in children with T-ALL. According to 25% of the IGLL1 transcription level (cutoff value:448), the enrolled children were divided into IGLL1 low expression group (17 cases) and IGLL1 high expression group (39 cases). Combined with clinical data, the correlation between the expression level of IGLL1 and prognosis of the patients was analyzed. RESULTS: The comparative analysis showed that the transcription level of IGLL1 was not correlated with the clinical characteristics of the patients, such as sex, age, bone marrow blast, white blood cell (WBC) count at initial diagnosis. The 5-year OS rate of patients with high IGLL1 expression was significantly higher than that of patients with low IGLL1 expression (76.9%±6.7% vs 47.1%±12.1%, P =0.018). Further comparison of relapse-free survival (RFS) rate between the two groups showed that the 5-year RFS rate of patients with high IGLL1 expression was higher than that of patients with low IGLL1 expression, but the difference between the two groups was not statistically significant (P =0.095). Multivariate COX analysis was conducted on common clinical prognostic factors (age, sex, WBC count at diagnosis, prednisone response on the 7th day, bone marrow response on the 15th day after treatment) and IGLL1 expression level, and the results showed that IGLL1 expression (P =0.012) and prednisone response (P =0.017) were independent risk factors for overall survival in pediatric T-ALL patients. CONCLUSION In pediatric T-ALL, the OS rate of children with high expression of IGLL1 gene was significantly higher than that of children with low expression of IGLL1 gene, and the expression level of IGLL1 gene was an independent factor affecting the survival of children with T-ALL, which suggests that IGLL1 is a marker of good clinical prognosis of children with T-ALL.

INTRODUCTION: Microinvasion (Mi) is often thought to be an interim stage between ductal carcinoma in situ (DCIS) and invasive ductal carcinoma. This study aimed to investigate the potential influence of Mi on survival and assess its correlations with clinicopathological parameters, prognosis and molecular markers. METHODS: The number of Mi foci in a cohort of 66 DCIS-Mi cases was assessed from haematoxylin and eosin-stained sections. Disease-free survival, clinicopathological parameters and biomarker expression were correlated with the number of Mi foci. RESULTS: Higher numbers of Mi foci were found in larger tumours (P = 0.031). CONCLUSION Greater extent of DCIS is associated with multifocal Mi.

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.

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.

OBJECTIVES: To investigate the effectiveness of high-dose chemotherapy combined with autologous hematopoietic stem cell transplantation (ASCT) in the treatment of children with high-risk neuroblastoma (NB). METHODS: A retrospective analysis was performed on 29 children with high-risk NB who were admitted to Shanghai Children's Hospital and were treated with high-dose chemotherapy combined with ASCT from January 2013 to December 2021, and their clinical features and prognosis were analyzed. RESULTS: Among the 29 children treated by high-dose chemotherapy combined with ASCT, there were 18 boys (62%) and 11 girls (38%), with a median age of onset of 36 (27, 59) months. According to the International Neuroblastoma Staging System, 6 children (21%) had stage III NB and 23 children (79%) had stage IV NB, and the common metastatic sites at initial diagnosis were bone in 22 children (76%), bone marrow in 21 children (72%), and intracalvarium in 4 children (14%). All 29 children achieved reconstruction of hematopoietic function after ASCT. After being followed up for a median time of 25 (17, 45) months, 21 children (72%) had continuous complete remission and 8 (28%) experienced recurrence. The 3-year overall survival rate and event-free survival rate were 68.9%±16.1% and 61.4%±14.4%, respectively. Presence of bone marrow metastasis, neuron-specific enolase ≥370 ng/mL and positive bone marrow immunophenotyping might reduce the 3-year event-free survival rate (P<0.05). CONCLUSIONS Children with high-risk NB who have bone marrow metastasis at initial diagnosis tend to have a poor prognosis. ASCT combined with high-dose chemotherapy can effectively improve the prognosis of children with NB with a favorable safety profile.

OBJECTIVE: To investigate the value of pre-treatment albumin/fibrinogen ratio (AFR) on the prognosis of patients with diffuse large B-cell lymphoma (DLBCL). METHODS: The data of DLBCL patients in the Affiliated Hospital of North Sichuan Medical College from April 2014 to March 2021 were retrieved, and 111 newly diagnosed patients who completed at least 4 cycles of R-CHOP or R-CHOP-like chemotherapy with complete data were included in the study. The clinical, laboratory examination and follow-up data of the patients were collected, and the receiver operating characteristic curve (ROC) was drawn according to patients' AFR before treatment and the survival status at the end of the follow-up, which could be used to preliminarily evaluate the predictive value of AFR for disease progression and patients' survival outcome. Furthermore, the correlation of AFR with the clinical and laboratory characteristics, progression-free survival (PFS) and overall survival (OS) was analyzed, and finally, univariate and multivariate Cox proportional hazard regression models were used to analyze factors affecting PFS and OS of DLBCL patients. RESULTS: The ROC curve indicated that AFR level had a moderate predictive value for PFS and OS in DLBCL patients, with the area under the curve (AUC) of 0.616 (P =0.039) and 0.666 (P =0.004), respectively, and the optimal cut-off values were both 9.06 for PFS and OS. Compared with high-AFR (≥9.06) group, the low-AFR (<9.06) group had a higher proportion of patients with Lugano III-IV stage ( P <0.001), elevated lactate dehydrogenase (P =0.007) and B symptoms (P =0.038). The interim analysis of response showed that the overall response rate (ORR) in the high-AFR group was 89.7%, which was significantly higher than 62.8% in the low-AFR group (P =0.001). With a median follow-up of 18.5 (3-77) months, the median PFS of the high-AFR group was not reached, which was significantly superior to 17 months of the low-AFR group (P =0.009). Similarly, the median OS of high-AFR group was not reached, either, which was significantly superior to 48 months of the low-AFR group (P < 0.001). In multivariate Cox regression analysis, AFR <9.06 was an independent risk factor both for PFS and OS (HR _PFS=2.047, P =0.039; HR _OS=4.854, P =0.001). CONCLUSION Pre-treatment AFR has a significant value for the prognosis evaluation in newly diagnosed DLBCL patients.

Objective: To investigate the early effect and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with a 10-day decitabine-containing conditioning regimen in the treatment of acute myeloid leukemia (AML) /myelodysplastic syndrome (MDS) . Methods: From April 2021 to May 2022, 31 AML/MDS patients who received allo-HSCT with a 10-day decitabine-containing conditioning regimen were analyzed. Results: AML (n=10), MDS-AML (n=6), CMML-AML (n=1), and MDS (n=14) were identified in 31 patients, 16 males, and 15 females, with a median age of 41 (20-55) yr. Neutrophils and platelets were successfully implanted in 31 patients (100%), with a median implantation duration of 12 (9-30) and 14 (9-42) days, respectively. During the preconditioning period, 16 patients (51.6%) developed oral mucositis, with 15 cases of Ⅰ/Ⅱ grade (48.4%) and one case of Ⅲ grade (3.2%). After transplantation, 13 patients (41.9%) developed CMV viremia, six patients (19.4%) developed hemorrhagic cystitis, and four patients (12.9%) developed a local infection. The median time of acute graft versus host disease (aGVHD) following transplantation was 33 (12-111) days. The cumulative incidence of aGVHD and Ⅲ/Ⅳ grade aGVHD was 41.9% (95% CI 26.9%-61.0%) and 22.9% (95% CI 13.5%-47.5%), respectively. There was no severe cGVHD, and mild and moderate chronic GVHD (cGVHD) incidence was 23.5% (95% CI 12.1%-43.6%). As of November 30, 2022, only one of the 31 patients had relapsed, with a 1-yr cumulative relapse rate (CIR) of 3.2% (95% CI 0.5%-20.7%). There was only one relapse patient death and no non-relapse deaths. The 1-yr overall survival (OS) and disease-free survival (DFS) rates were 92.9% (95% CI 80.3%-100%) and 96.8% (95% CI 90.8%-100%), respectively. Conclusions: A 10-day decitabine-containing conditioning regimen for allo-HSCT reduced relapse and was safe and feasible in treating AML/MDS.
