Flavonoids as therapeutic agents for epilepsy: unveiling anti-inflammatory and antioxidant pathways for novel treatments.

Epilepsy, a chronic neurological disorder affecting millions globally, is often exacerbated by neuroinflammation and oxidative stress. Existing antiepileptic drugs primarily manage symptoms, leaving the disease's progression largely unaddressed. Flavonoids, ubiquitous plant metabolites with potent anti-inflammatory and antioxidant properties, show promise in epilepsy treatment. Unlike conventional therapies, they target multiple pathophysiological processes simultaneously, offering a comprehensive approach to this complex neurological disorder. This review explores the dual role of flavonoids in mitigating neuroinflammation and reducing oxidative stress through various molecular pathways. By inhibiting key inflammatory mediators and pathways such as NF-κB, MAPK, JNK, and JAK, flavonoids offer neuronal protection. They enhance the body's natural antioxidant defenses by modulating enzyme activities, including superoxide dismutase, catalase, and glutathione peroxidase. Moreover, flavonoids influence crucial antioxidant response pathways like PI3K/AKT, Nrf2, JNK, and PKA. Despite their therapeutic promise, the low bioavailability of flavonoids poses a considerable challenge. However, cutting-edge strategies, including nanotechnology and chemical modifications, are underway to improve their bioavailability and therapeutic efficacy. These advancements support the potential of flavonoids as a valuable addition to epilepsy treatment strategies.

Clinical Efficacy of Programmed Cell Death Ligand 1 Antibody in Treatment of Extranodal Natural Killer/T-Cell Lymphoma With Hemophagocytic Lymphohistiocytosis.

Extranodal natural killer/T-cell lymphoma-associated hemophagocytic lymphohistiocytosis (ENKTCL-LAHS) is a rare disease with poor prognosis. Currently, there are no well-established treatments for LAHS. Almost 50% of patients experience relapsed or refractory disease to anti-hemophagocytic lymphohistiocytosis (HLH) treatment, and the regimen for salvage therapy is limited. We report a case of ENKTCL-LAHS that was successfully treated with a programmed cell death ligand 1 (PD-L1) antibody (sugemalimab) alone and provide a literature review on existing ENKTCL-LAHS treatment options. A 31-year-old man with relapsed ENKTCL complicated by HLH was admitted to our hospital. Following the administration of the PD-L1 antibody sugemalimab, fever was resolved, Epstein-Barr virus (EBV) DNA copy number was negative, and HLH-related blood biochemical markers were decreased in the patient. Consequently, the patient achieved complete remission with a progression-free time (PFS) of 44 months. The prognosis of ENKTCL-LAHS is extremely poor, and the clinical treatment of ENKTCL-HLH is challenging. No previous reports exist regarding the use of PD-L1 antibodies in ENKTCL-LAHS treatment. This study is the first to report a patient with ENKTCL-LAHS treated with the PD-L1 antibody alone, who achieved a long PFS of 44 months. Our results suggest the effectiveness and safety of sugemalimab in the treatment of ENKTCL-LAHS; however, more clinical cases are required for validation. The PD-L1 antibody presents a novel treatment option for patients with ENKTCL-LAHS and warrants further clinical promotion.

Nomograms to predict progression of disease within 24 months in patients with localized natural killer/T-cell lymphoma.

Aims: Progression of disease within 24 months (POD24) is associated with poor survival in some subtypes of lymphoma.The aim is to identify high-risk patients with localized extranodal natural killer/T-cell lymphoma (ENKTL) and to define clinical factors associated with the risk of early recurrence after antitumor treatment. Methods: The authors retrospectively analyzed 330 cases with localized ENKTL, of which 89 experienced POD24. Results: The 5-year overall survival of the POD24 group was extremely inferior to that of the non-POD24 group. Risk factors for POD24 were Eastern Cooperative Oncology Group performance status ≥2, response evaluation (non-complete remission) after first-line treatment and elevated lactate dehydrogenase concentrations. Also, higher Epstein-Barr virus DNA titer was related to POD24. Based on these data with or without the availability of Epstein-Barr virus DNA, the authors conducted two nomograms to predict POD24, which showed good accuracy with high C statistics. Conclusion: The results showed that POD24 could serve as a marker to identify patients whose medical needs were unmet in ENKTL.

Lymphoma-associated hemophagocytic syndrome: a retrospective study from a single center.

Lymphoma-associated hemophagocytic syndrome (LAHS) is a rare and life-threatening clinical syndrome with rapidly deteriorating health and high mortality. We retrospectively analyzed clinical features and prognostic factors from 117 patients diagnosed with LAHS. The cumulative incidence rate of LAHS was 4.0% (117/2906). Patients were classified into B-cell LAHS (B-LAHS, n = 22) and T/natural killer (NK)-cell LAHS (T/NK-LAHS, n = 95) groups. Patients with T/NK-LAHS were younger and had lower neutrophil counts and fibrinogen values, higher LDH and transaminase levels, and were more likely to develop hemophagocytic syndrome (HPS) during the clinical course than those with B-LAHS. The median survival time for the entire cohort was 57 days, and for the T/NK-LAHS and B-LAHS groups, it was 52 and 154 days, respectively, after the diagnosis of LAHS. Patients with B-LAHS had superior 1-year OS (p = 0.003, 36.4% versus 14.5%) compared with those with T/NK-LAHS. Prognostic factor analysis revealed that elevated LDH levels (LDH > 1000 IU/L) (p = 0.004), T/NK-cell lineage (p < 0.001) and HPS onset at relapse (p = 0.001) were strongly associated with early death. For patients diagnosed with T/NK-LAHS, in addition to LDH levels and HPS onset status, high EBV-DNA copies (≥4,450 copies/mL) (p = 0.016) were also related to poor prognosis of T/NK-LAHS.

The value of prognostic nutritional index in nasal-type, extranodal natural killer/T-cell lymphoma.

Extranodal natural killer/T-cell lymphoma (ENKTL) is an aggressive disorder with heterogeneous clinical characteristics and poor prognosis. The combined value of baseline serum albumin level and absolute peripheral lymphocyte count showed prognostic information in a variety of malignancies, but its evidence is limited in ENKTL. The purpose of this study is to evaluate the impact of prognostic nutritional index (PNI) in ENKTL, and to provide some nutritionally and immunologically relevant information for better risk stratification. We conducted a retrospective study in 533 patients newly diagnosed with ENKTL. The PNI was calculated as albumin (g/L) + 5 × lymphocyte count (109/L). The optimal cutoff values for serum albumin and lymphocyte count were 40.6 g/L and 1.18 × 109/L, respectively, and 47.3 for PNI. After a median follow-up of 70 months, the 5-year overall survival (OS) and progression-free survival (PFS) were 56.2% and 49.5%, respectively. Patients in low PNI group had more unfavorable clinical features, and tended to have worse 5-year OS and PFS compared with those in high PNI group. According PNI-associated prognostic score, patients were classified into different risk groups. Significant difference has been found in 5-year OS and PFS in different risk groups. When PNI and PNI-associated prognostic score were superimposed on the International Prognostic Index (IPI), prognostic index of natural killer lymphoma (PINK), or nomogram-revised risk index (NRI) categories, the PNI and PNI-associated prognostic score provided additional prognostic information. Therefore, PNI and PNI-associated prognostic score could be independent prognostic factors for ENKTL and may be useful for risk stratification and clinical decision-making.

A novel prognostic index for sporadic Burkitt lymphoma in adult patients: a real-word multicenter study.

BACKGROUND: Adult sporadic Burkitt lymphoma (BL) is a rare but highly aggressive subtype of lymphoma which lacks its own unique prognostic model. Systemic inflammatory biomarkers have been confirmed as prognostic markers in several types of malignancy. Our objective was to explore the predictive value of pretreatment inflammatory biomarkers and establish a novel, clinically applicable prognostic index for adult patients with sporadic BL. METHODS: We surveyed retrospectively 336 adult patients with newly diagnosed sporadic BL at 8 Chinese medical centers and divided into training cohort (n = 229) and validation cohort (n = 107). The pretreatment inflammatory biomarkers were calculated for optimal cut-off value. The association between serum biomarkers and overall survival (OS) was analyzed by Kaplan-Meier curves and Cox proportional models. The risk stratification was defined based on normal LDH level, Ann Arbor stage of I and completely resected abdominal lesion or single extra-abdominal mass < 10 cm. RESULTS AND CONCLUSIONS: Univariate and multivariate analyses revealed that platelets< 254 × 109/L, albumin< 40 g/L, lactate dehydrogenase≥334 U/L independently predicted unfavorable OS. We used these data as the basis for the prognostic index, in which patients were stratified into Group 1 (no or one risk factor), Group 2 (two risk factors), or Group 3 (three risk factors), which were associated with 5-year OS rates of 88.1, 72.4, and 45%, respectively. In the subgroup analysis for high-risk patients, our prognostic model results showed that high-risk patients with no more than one adverse factor presented a 5-year survival rate of 85.9%, but patients with three adverse factors had a 5-year survival rate of 43.0%. Harrell's concordance index (C-index) of the risk group score was 0.768. Therefore, the new prognostic model could be used to develop risk-adapted treatment approaches for adult sporadic BL.

Clinical management and susceptibility of primary hepatic lymphoma: A cases-based retrospective study.

BACKGROUND: The liver as a primary site of lymphoma is rarely seen, they are usually misdiagnosed as hepatocellular carcinoma, etc. In 2017, a review of primary hepatic lymphoma (PHL) was done in immunocompetent diffuse large B-cell lymphoma (DLBCL) patients. Yet questions that include treatment choosing or susceptibility of immunoincompetent patients remain disputable. AIM: To investigate the clinical characteristics of patients with PHL. METHODS: We collected PHL cases on PubMed, and extracted demographic and clinicopathological data to perform a systematic analysis. Survival analysis regarding age, lactate dehydrogenase (LDH), liver function abnormality (LFA), and treatment modalities were conducted. The Kaplan-Meier method and Cox regression were used to identify risk factors. RESULTS: Of 116 PHL patients with DLBCL (62.1%) as the most common subtype. Biopsy methods before surgery produced a 97% positive rate. Progression-free survival (PFS) was significantly shortened in patients with elevated LDH [Hazard ratio (HR): 3.076, 95% confidence interval (CI): 1.207-7.840, P = 0.018] or LFA (HR: 2.909, 95%CI: 1.135-7.452, P = 0.026). Univariate Cox regression analysis suggesting that LDH, liver function, B symptom, hepatosplenomegaly, and lesion were significantly associated with PHL patients survival (P < 0.05). Heavy disease burden was observed in deceased patients. A few PHL patients (3.4%) have slightly higher tumor markers. CONCLUSION: PHL patients with elevated LDH and LFA tend to have shorter PFS. Biopsy before treatment in undecided patients with no tumor markers exceeds upper limits has the most essential clinical significance, especially in immunoincompetent patients.

How to Identify Patients at High Risk of Developing Nasal-Type, Extranodal Nature Killer/T-Cell Lymphoma-Associated Hemophagocytic Syndrome.

Nasal-type, extranodal nature killer (NK)/T-cell lymphoma-associated hemophagocytic syndrome (NK/T-LAHS) is a rare and life-threatening disease, requiring investigation of risk stratification. We conducted a retrospective study and proposed nomograms to predict NK/T-LAHS. The discriminative ability and calibration of the nomograms for prediction were tested using C statistics and calibration plots. We analyzed 533 patients with extranodal NK/T-cell lymphoma (ENKTL), out of which 71 were diagnosed with hemophagocytic syndrome (HPS), with a cumulative incidence of 13.3%. Significant difference for 2-year survival was found between patients with and without HPS (14.7% vs. 77.5%). Analyses showed that Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≥2, B symptoms, and bone marrow (BM) invasion were significantly associated with NK/T-LAHS. We used these data as the basis to establish a nomogram of risk index for ENKTL (RINK). In 335 patients with available data for Epstein-Barr virus DNA (EBV-DNA), we found high viral copies (≥4,450 copies/ml) were correlated with NK/T-LAHS. When these data were added to RINK, we developed another nomogram that included EBV-DNA data (RINK-E). The nomograms displayed good accuracy in predicting NK/T-LAHS with a C-statistics of 0.919 for RINK and a C-statistics of 0.946 for RINK-E, respectively. The calibration chart also showed an excellent consistency between the predicted and observed probabilities. The proposed nomograms provided individualized risk estimate of HPS in patients with ENKTL.

[Bortezomib Inhibits Extranodal Natural Killer/T Cell Lymphoma, Nasal Type by Targeting NF-κB Signaling Pathway].

OBJECTIVE: To investigate the anti-tumor effect of bortezomib on extranodal natural killer/T cell lymphoma, nasal type (ENKTL). METHODS: SNK-6 cells were treated with different mass concentrations of bortezomib (0, 1, 2, 4, 5, 6 ng/mL) for 24, 48, 72 h, and different concentrations of nuclear factor-kappa B (NF-κB) signaling pathway inhibitor BAY11-7082 (0, 1, 2, 2.5, 5, 10, 20 µmol/L) for 24 h respectively, then the cell viability was measured by CCK8 kit and the half inhibitory concentration (IC 50) was calculated. SNK-6 cells were treated with 30µmol/L Z-VAD-FMK (Pan-caspase inhibitor)+3ng/mL bortezomib, and 5, 10 µmol/L BAY11-7082+3 ng/mL bortezomib for 24 h respectively, then the cell viability was measured by CCK8 kit. After treatment of SNK-6 cells with different mass concentrations of bortezomib for 24 h, apoptosis was detected by AnnexinⅤ/PI flow cytometry; the expression of apoptosis-related protein Caspase-3, poly ADP-ribose polymerase (PARP) and Bcl-2 and NF-κB signaling pathway key proteins P65 and P100/P52 were detected by Western blot. RESULTS: Bortezomib inhibited the proliferation of SNK-6 cells in a dose-dependent manner ( P<0.05), and IC 50( (2.87±0.06) ng/mL) at 24 h was lower than that at 48 h and 72 h ( P<0.05). BAY11-7082 also inhibited the proliferation of SNK-6 cells with an IC 50= (9.73±0.36) µmol/L at 24 h. The combination treatment indicated that Z-VAD-FMK could attenuate the inhibitory effect of bortezomib on the proliferation of SNK-6 cells ( P<0.05), while BAY11-7082 could enhance the inhibitory effect of bortezomib on the proliferation of SNK-6 cells ( P<0.05). After treatment of SNK-6 cells with bortezomib for 24 h, apoptosis-related protein Caspase-3 cleavage, PARP activation, and Bcl-2 cleavage; NF-κB signaling pathway-related protein P65 phosphorylation level decreased, and P52 decreased. CONCLUSION: Bortezomib inhibits ENKTL cells proliferation by inhibiting NF-κB signaling pathway and induces apoptosis of ENKTL cells via mitochondria-mediated caspase pathway.

Survivin is a prognostic marker and therapeutic target for extranodal, nasal-type natural killer/T cell lymphoma.

BACKGROUND: The relationship between survivin and extranodal, nasal-type natural killer/T cell lymphoma (ENKTCL) was unclearly established yet. We here studied the potential prognostic roles of survivin and its implication as a target in ENKTCL therapy. METHODS: ENKTCL patients' peripheral blood were collected and tested by ELISA. ENKTCL cell lines were cultured with or without survivin inhibitor and tested by MTT and Flow cytometry. According to the gene expression profiles from the ArrayExpress Archive under E-TABM-702, survivin co-regulated cluster was established by Coupled Two-way Clustering Algorithm. RESULTS: Seventeen point six percent of total 17 ENKTCL patients were serum survivin-positive. These patients had poorer outcome than that of negative cases (P<0.01). Analysis of survivin co-regulation genes in ENKTCL revealed that survivin was significantly involved in pluripotency, drug resistance, cell cycle and proliferation, indicating that it should be one of key regulators in ENKTCL and might be a latent therapeutic target. Our results just showed that YM155, a survivin inhibitor, had strong anti-tumor effect on ENKTCL cell lines in a dose dependent manner. It increased sub-G1 phase population and reduced G1- and G2-M phase populations (P<0.05). In addition, combining YM155 with DDP induced a larger decrease in cell viability than either agent alone and had a higher inhibition rate than Bliss index, suggesting their synergistic inhibition. CONCLUSIONS: We concluded that survivin was a potential prognostic marker and a critical regulatory molecule in the pathological process of ENKTCL. It would be a promising target in drugs discovery for ENKTCL therapy.

Prognostic impact of absolute lymphocyte count/absolute monocyte count ratio and prognostic score in patients with nasal-type, extranodal natural killer/T-cell lymphoma.

Nasal-type, extranodal natural killer/T-cell lymphoma is a heterogeneous disorder with poor prognosis, requiring risk stratification in this population. The combined value of baseline absolute lymphocyte count and absolute monocyte count provided prognostic information in some malignancies. However, the evidence requires validation in extranodal natural killer/T-cell lymphoma. Aiming to investigate the prognostic significance of absolute lymphocyte count/absolute monocyte count ratio and absolute lymphocyte count/absolute monocyte count prognostic score for extranodal natural killer/T-cell lymphoma, a retrospective research was carried out. A total of 264 patients with newly diagnosed extranodal natural killer/T-cell lymphoma were analyzed in this study. The patients' absolute lymphocyte count and absolute monocyte count tested at initial diagnosis were collected. Receiver operating curve analysis showed that the optimal cut-off values for absolute lymphocyte count and absolute monocyte count were 1.0 × 109 and 0.5 × 109L-1, respectively, and for absolute lymphocyte count/absolute monocyte count ratio was 2.85. After a median follow-up of 27 months (range 1-87 months), the 3-year overall survival and progression-free survival was 75.4% and 67.6%, respectively. Patients with absolute lymphocyte count/absolute monocyte count ratio ≥ 2.85 had better 3-year overall survival and progression-free survival than those with absolute lymphocyte count/absolute monocyte count ratio <2.85 (p < 0.001). According to absolute lymphocyte count/absolute monocyte count prognostic score, significant difference has been noticed in 3-year overall survival and progression-free survival (p < 0.001) and high absolute lymphocyte count/absolute monocyte count prognostic score was associated with poorer survival. The International Prognostic Index and Korean Prognostic Index were used for prognosis and showed no significant difference. When adding absolute lymphocyte count/absolute monocyte count ratio and absolute lymphocyte count/absolute monocyte count prognostic score to the International Prognostic Index and Korean Prognostic Index model, additional prognostic information was found. These results suggest that absolute lymphocyte count/absolute monocyte count ratio and absolute lymphocyte count/absolute monocyte count prognostic score might be useful prognostic factors in extranodal natural killer/T-cell lymphoma.

A phase II prospective study of the "Sandwich" protocol, L-asparaginase, cisplatin, dexamethasone and etoposide chemotherapy combined with concurrent radiation and cisplatin, in newly diagnosed, I/II stage, nasal type, extranodal natural killer/T-cell lymphoma.

Nasal-type, extranodal NK/T cell lymphoma (ENKTCL) is a special type of lymphomas with geographic and racial specificity. Up to now, the standard first-line treatment is still not unified. In our previous report, the "sandwich" protocol produced good results. Continuing to use the "sandwich" mode, a new chemotherapy composed of L-asparaginase, cisplatin, etoposide and dexamethasone (LVDP) plus concurrent chemoradiotherapy (CCRT) was conducted in more patients with newly diagnosed, I/II stage ENKTCL. The results showed that 66 patients were enrolled. Overall response rate was 86.4% including 83.3% complete response and 3.0% partial remission. With the median follow-up of 23.5 months, 3-year overall survival and 3-year progression-free survival were 70.1% and 67.4%, respectively. The survival rate in stage II and extra-cavity stage I was significantly less than that in limited stage I (p < 0.05). Therefore, we thought that the "sandwich" mode was worthy of being generalized and LVDP combined with CCRT was an effective protocol for I/II stage ENKTCL. But this regimen was not suitable for all stage I/II patients and warrants larger sample and layering investigation. This study was a registered clinical trial with number ChiCTR-TNC-12002353.

A clinical study of 21 patients with hemophagocytic syndrome in 295 cases diagnosed with nasal type, extranodal nature killer/T cell lymphoma.

Nasal type, extranodal nature killer (NK)/T cell lymphoma-associated hemophagocytic syndrome (NK/T-LAHS) is a rare and fatal disorder with extremely poor prognosis. To investigate its clinical characteristics and risk factors, we retrospectively analyzed 295 patients with nasal type, extranodal nature killer/T cell lymphoma, of which 21 were diagnosed with hemophagocytic syndrome, with a cumulative incidence of 7.1%. The most frequently clinical characteristics were fever, lymphadenopathy, hepatosplenomegaly, pancytopenia, hyperferritinemia, liver dysfunction, hypertriglyceridemia, hypofibrinogenemia and evaluated lactate dehydrogenase (LDH) level. After a median follow-up of 27 months, the 2-year survival for the 295 patients was 74.6%. Significant difference for 2-year survival was found between patients with and without hemophagocytic syndrome (4.8% vs. 80.0%, P<0.001). After developing hemophagocytic syndrome, all patients survived no more than 3 months, with a median survival of 35 days. Risk factors for NK/T-LAHS were bone marrow (BM) involvement (P = 0.019; relative risk, 13.649; 95% confidence interval (CI): 1.538-121.103), hepatosplenomegaly (P = 0.003; relative risk, 9.616; 95%CI: 2.154-42.918), and elevated LDH level (>314U/L) (P = 0.038; relative risk, 6.293; 95%CI: 1.108-35.735). We conducted a risk model for all 295 patients based on the 3 adverse factors as follows: low risk (233 cases, 79.0%), no factor; intermediate risk (43 cases, 14.6%), one factor; high risk (19 cases, 6.4%), 2 or 3 factors. The probabilities for developing LAHS were 0.9% for low-, 14.0% for intermediate-, and 68.4% for high-risk group. Significant differences in the 3 risk groups were observed (P<0.001).

Serum B-cell activating factor predicts prognosis in nasal type, extranodal NK/T cell lymphoma.

B-cell activating factor (BAFF) plays important roles in a variety of lymphoid malignancies. Compared with healthy adults, patients with non-Hodgkin lymphoma had higher level of serum BAFF, and it corresponded with disease severity, response for therapy and clinical outcome. Latent membrane protein 1 (LMP1) encoded by Epstein-Barr virus (EBV) which is a known agent of nasal, extranodal NK/T cell lymphoma (ENKTCL) can switch the BAFF activating promoter leading to higher expression of BAFF in EBV-related tumor cells. However, the relationship between BAFF and ENKTCL has not been reported. Here we proposed a hypothesis that BAFF might play a regulatory role in ENKTCL development and maintenance. Our results showed that serum BAFF in ENKTCL patients was significantly higher than that in control group and negatively correlated with patients' survival. It may be a valuable prognostic factor and deserved further study.

Body mass index as a prognostic factor in patients with extranodal natural killer/T-cell lymphoma, nasal type.

Epidemiological evidence has shown that body mass index (BMI) can predict survival in several types of cancer. However, the role of BMI in extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is still unclear. This retrospective single-center study included 251 newly diagnosed patients to determine the prognostic value of BMI in ENKTL. Of these, 203 patients received chemoradiotherapy, 37 received chemotherapy alone, 8 received radiotherapy alone, and 3 received only best supportive care. With a median follow-up of 28 months, the estimated 3-year overall survival (OS) and progression-free survival (PFS) rates were 64.4% and 60.9%, respectively. The receiver-operating characteristic curve showed that 20.8 kg/m2 was the optimal cut-off of BMI to predict survival. BMI < 20.8 kg/m2 was associated with lower 3-year OS (52.8% vs. 72.9%, P = 0.001) and PFS (48.8% vs. 69.8%, P < 0.001) rates. Multivariate analysis indicated that BMI, performance status, lactate dehydrogenase (LDH) levels, chemotherapy, and radiotherapy were independent prognostic factors for OS. Furthermore, BMI, number of extranodal sites, performance status, LDH, and radiotherapy were predictive of PFS. These results suggest that BMI at the cut-off of 20.8 kg/m2 might be a prognostic factor in patients with ENKTL.

Five-year analysis from phase 2 trial of "sandwich" chemoradiotherapy in newly diagnosed, stage IE to IIE, nasal type, extranodal natural killer/T-cell lymphoma.

The "sandwich" protocol, was first proposed by us and comprised of l-asparaginase, vincristine, and prednisone chemotherapy with radiotherapy, results in 2-year overall survival and progression-free survival rates that surpass traditional therapies for patients with newly diagnosed, stage IE-IIE, nasal type, extranodal natural killer/T-cell lymphoma. The results had been published by cancer. These patients were followed up over a median period of 67 months, for which updates and the results of prognostic factors analyses are presented. The 5-year overall survival and progress-free survival rates were both 64%. The highest rates of death occurred during the first 6 months, and between the second and third year after enrollment. The initial therapeutic response (odds ratio = 5.83; P = 0.001) and B symptoms (odds ratio = 6.13; P = 0.043) were significant prognostic factors for overall survival. However, the international prognostic index was not significant for progress-free survival and overall survival. There were no severe long-term side effects. These results indicate that the "sandwich" protocol may benefit the long-term survival of patients with newly diagnosed stage IE-IIE, nasal type, extranodal natural killer/T-cell lymphoma. However, additional studies with larger samples are required to confirm these results. This study is registered at www.Chictr.org (ChicTR-TNC-09000394).

3D conformal radiotherapy combined with transcatheter arterial chemoembolization for hepatocellular carcinoma.

AIM: To compare transcatheter arterial chemoembolization (TACE) and 3D conformal radiotherapy (3D-CRT) with TACE monotherapy in hepatocellular carcinoma (HCC). METHODS: We searched all the eligible studies from the Cochrane Library, PubMed, Medline, Embase, and CNKI. The meta-analysis was performed to assess the survival benefit, tumor response, and the decline in α-fetoprotein (AFP) level. According to the heterogeneity of the studies, pooled OR with 95%CI were calculated using the fixed-effects or random-effects model. An observed OR > 1 indicated that the addition of 3D-CRT to TACE offered survival benefits to patients that could be considered statistically significant. Statistical analyses were performed using Review Manager Software. RESULTS: Ten studies met the criteria to perform a meta-analysis including 908 HCC participants, with 400 patients in the TACE/3D-CRT combination group and 508 in the TACE alone group. TACE combined with 3D-CRT significantly improved 1-, 2- and 3-year overall survival compared with TACE monotherapy (OR = 1.87, 95%CI: 1.37-2.55, P < 0.0001), (OR = 2.38, 95%CI: 1.78-3.17, P < 0.00001) and (OR = 2.97, 95%CI: 2.10-4.21, P < 0.00001). In addition, TACE plus 3D-CRT was associated with a higher tumor response (complete remission and partial remission) (OR = 3.81; 95%CI: 2.70-5.37; P < 0.00001), and decline rates of AFP level (OR = 3.24, 95%CI: 2.09-5.02, P < 0.00001). CONCLUSION: This meta-analysis demonstrated that TACE combined with 3D-CRT was better than TACE monotherapy for patients with HCC, which needs to be confirmed by large multicenter trials．

Survey on Chinese breast cancer patients' husbands toward breast conserving surgery.

PURPOSE: Husband, as an important member of the family, greatly impacts the treatment decision. In this study, we sought to evaluate the attitudes toward breast conserving surgery (BCS) in Chinese breast cancer patients' husbands and explore the influencing factors. METHODS: A self-structured questionnaire was distributed to the husbands of 1600 wives with breast cancer, eliciting information on their general information, the level of understanding of BCS, attitudes toward BCS and affecting reasons. RESULTS: In all, 1468 (91.8%) husbands completed the questionnaire. Collation of the responses showed that only 3.0% had a good understanding of BCS and 81.5% did not favor BCS. Patients' husbands perception were associated with their age, religion, occupation, educational background, method of payment of medical expenses, understanding the disease condition and doctor's recommendations (p<0.05). The top reason was "fear of incomplete resection, which could easily lead to recurrence and metastasis". CONCLUSIONS: This study indicates that Chinese husbands have skepticism and lack comprehensive and correct understanding for BCS. Meanwhile, their desire of obtaining knowledge was not strong. The results suggest a need for fundamental changes in husbands' education to ensure that they are able to obtain enough information so that they can help their wives make educated decisions.

The role of palliative chemotherapy for terminally ill patients with advanced NSCLC.

BACKGROUND: To evaluate the conditions of palliative chemotherapy in terminally ill patients with advanced non-small cell lung cancer (NSCLC), and to discuss the potential factors that affect the prognosis of these patients. METHODS: All 205 terminally ill patients with advanced NSCLC, who died in our hospital during the period from 2006 to 2010, were included in the study. Basic information was collected and details for the treatment of patients, related to overall survival, were evaluated. RESULTS: One hundred and fifty-nine out of 205 patients (77.6%) were treated with palliative chemotherapy. Of these, 59.7% patients were treated with palliative chemotherapy in the last three months and 27.7% patients in the last one-month, prior to their expiration, respectively. In addition, 22.0% of the 159 patients were treated with palliative chemotherapy for the first time in the last three months and 10.1% in the last month of their final days. We have shown that patients treated with palliative chemotherapy in their last three and final month had a shorter overall survival rate than those patients who were not treated with palliative chemotherapy. CONCLUSION: A large proportion of patients with advanced NSCLC received palliative chemotherapy near the end of their life. However, our results were not in favor of palliative chemotherapy in the last three or final month of life.

Survey on breast cancer patients in China toward breast-conserving surgery.

OBJECTIVE: We sought to investigate attitudes toward breast-conserving therapy (BCS) in early-stage breast cancer (EBC) patients from P. R. China and assess the factors influencing their decision. BACKGROUND: There exists geographical difference in decision to perform mastectomy or BCS for EBC patients. To date, there has been no report on attitudes toward BCS or factors influencing the surgical choice in mainland China. METHODS: A structured questionnaire was delivered to 1800 EBC patients. The questionnaire elicited information about general patients' characteristics, attitudes toward BCS, the roles of doctors and spouses, the levels of understanding of BCS, and the reasons for their preferences. RESULTS: Of 1590 participants, only 7.3% anticipated BCS and this was significantly associated with patient age, income, occupation, martial status, education, levels of self-understanding of the disease, and doctors' and spouses' suggestions (P<0.05). Approximately 70% of doctors (71.0%) and 40% spouses (39.6%) advised patients not to conserve their breasts. Although the percentage of patients endorsing BCS was higher than that of those opposing it (43.7 vs 15.1%) and more patient believed BCS was beneficial for women (39.2%), even if given another opportunity, only 32.5% of patients preferred to choose it. Moreover, the level of understanding BCS among patients is low (well-known: less-known: never-heard, 2.3 vs 47.4 vs 13.3%). CONCLUSIONS: These results suggested that Chinese EBC patients lack accurate and comprehensive understanding of BCS. More efforts are needed to educate breast cancer patients in mainland China toward BCS.
