ABSTRACT
PURPOSE: ASTRIS study aimed the largest to evaluate the effectiveness and safety of second- or higher-line osimertinib in patients with advanced/metastatic epidermal growth factor receptor (EGFR) T790M mutation-positive non-small cell lung cancer (NSCLC) in the real-world setting. Here we report the results of Chinese patients in ASTRIS study. METHODS: Adults with EGFR T790M-positive advanced NSCLC pretreated with EGFR-tyrosine kinase inhibitor (EGFR-TKI), having a WHO performance status score of 0-2 and asymptomatic, stable central nervous system (CNS) metastases were included. All patients received once-daily osimertinib 80 mg orally. The outcomes included investigator-assessed clinical response, progression-free survival (PFS), time-to-treatment discontinuation (TTD), and safety. RESULTS: A total of 1350 patients were included. Response rate was 55.7% (95% confidence interval [CI] 0.53-0.58). The median PFS and the median TTD were 11.7 months (95% CI 11.1-12.5) and 13.9 months (95% CI 13.1-15.2), respectively. Overall, 389 patients (28.8%) had at least one protocol-specified adverse event (AE); AEs of interstitial lung diseases/pneumonitis-like events and QT prolongation were reported in 3 (0.2%) and 59 (4.4%) patients, respectively. CONCLUSION: Osimertinib was effective in Chinese patients with T790M-positive NSCLC who had progressed after first- or second-generation EGFR-TKI in real-word setting and the results were consistent with ASTRIS study overall population and AURA studies. No new safety signals or events were identified. CLINICAL TRIAL NUMBER: NCT02474355.

OBJECTIVE: Due to the rarity of angioimmunoblastic T-cell lymphoma (AITL), very limited data concerning its incidence patterns and prognostic factors are available. This study aimed to explore the incidence, characteristics, survival outcomes, and prognostic factors of AITL. METHODS: Age-adjusted incidence and temporal trends were calculated based on 1247 AITL patients from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER)-13 database. A total of 1525 AITL patients from the SEER-18 database and 43 patients from our single center were included for survival analysis and nomogram construction. RESULTS: The age-adjusted incidence for overall cohort was 0.123 [95% confidence interval (CI), 0.117-0.131) per 100 000 during 1992-2017. The overall incidence increased steeply at the rate of 15.3% (95%CI 11.0%-19.8%, P<0.001) per year during 1992-2004, but remained stable during 2004-2017 (P=0.200). Similar incidence trends were observed in age, sex, and stage subgroups. The final nomograms consisted of four variables: age at diagnosis, sex, Ann Arbor stage, and primary site. The concordance index (C-index) of the nomogram for 5-year overall survival prediction was 0.717, 0.690 and 0.820 in the training cohort, validation cohort-1 and cohort-2, respectively. Regarding the disease-specific survival (DSS), the nomogram also demonstrated a good discrimination level, with the C-index for predicting the probability of DSS at 5 years of 0.716, 0.682 and 0.813 for the three cohorts, respectively. The calibration displayed good concordance between the nomogram-predicted and actual observed outcomes. CONCLUSION: The age-adjusted incidence for AITL was low during 1992-2017. The incidence continuously increased during 1992-2004, but remained stable during 2004-2017. The nomograms as proposed may provide a favorable and accurate prognostic survival prediction in AITL.

INTRODUCTION: Despite recent advances in NSCLC treatment, specific data on the elderly population remain limited. In this post hoc subgroup analysis of the East Asia S-1 Trial in Lung Cancer (EAST-LC) trial, we compared S-1 and docetaxel (DTX) in patients aged 70 years old and above with pretreated advanced NSCLC. METHODS: Patients were randomly assigned (1:1) to receive S-1 (orally, twice daily on d 1-28 of a 6-wk cycle) or DTX (intravenously, on d 1 of a 3-wk cycle). The initial S-1 dose was 80, 100, or 120 mg/day on the basis of body surface area, and the DTX doses were 60 mg/m2 (Japan) or 75 mg/m2 (outside Japan). The primary end point was overall survival, and secondary end points included progression-free survival, response rate, quality of life (QOL) using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core-30, and safety. RESULTS: Among 189 patients aged 70 years and above assessed as the full analysis set, baseline characteristics were generally similar between treatment arms. The median overall survival was 14.7 (S-1) versus 12.1 months (DTX); the hazard ratio was equal to 0.76, with a 95% confidence interval (CI) of 0.54-1.07. The median progression-free survival was similar in both arms (both 4.1 mo, hazard ratio = 0.84, 95% CI: 0.60-1.18); and the response rate was 12.9% (S-1) and 14.0% (DTX). The adjusted mean QOL score difference (S-1-DTX until wk 48) was 7.41 (95% CI: 0.37-14.46). Safety profiles were generally consistent with those of the overall EAST-LC population. CONCLUSIONS: S-1 revealed comparable efficacy, safety, and QOL versus DTX in pretreated elderly patients with advanced NSCLC. Results were consistent with the overall EAST-LC data.
ABSTRACT
BACKGROUND: The aim of the study was to define the clinical significance of circulating tumor cells (CTCs)/circulating tumor endothelial cells (CTECs) and their subtypes in small cell lung cancer (SCLC) patients. METHODS: CTCs/CTECs and their subtypes were determined using SE-iFISH technology in 33 SCLC patients before initial treatment (B1), after two cycles of chemotherapy (B2), at the completion of chemotherapy (B3), and disease progression (B4). The correlations with clinical characteristics, progression-free survival (PFS), and overall survival (OS) were analyzed. RESULTS: CTCs and CTECs were detected in 96.6% and 65.5% of patients, respectively. Patients had higher levels of CTCs compared with CTECs in circulation (p < 0.05). Extensive-stage SCLC patients tended to have higher CTEC counts (p = 0.035), and the detection of CTC-white blood cell (CTC-WBC) clusters was associated with a worse response to treatment (p = 0.030). Patients with CTC-WBC clusters at B1 (17.3 vs. 22.6 months, p = 0.041) and B2 (19.9 vs. 25.2 months, p = 0.018) had significantly shorter OS than those with no detection. Additionally, their presence was revealed as independent predictors for a worse OS in multivariable analyses (B1: HR 9.3, 95% CI: 1.4-48, p = 0.0079; B2: HR 4.4, 95% CI: 1.1-18, p = 0.041). A high CTC level at B4 was an adverse prognostic factor for SCLC patients (PFS: 8.7 vs. 22.5 months, p = 0.0026; OS: 19 months vs. not reached, p = 0.0086). CTC clusters and CTECs also showed prognostic values. CONCLUSIONS: The presence of CTC-WBC clusters at baseline and after two-cycle chemotherapy and the total CTC counts at the completion of chemotherapy are strong predictors for the prognostic survival of SCLC patients receiving first-line treatment.

BACKGROUND: Bendamustine was approved in China on May 26th, 2019 by the National Medical Product Administration for the treatment of indolent B-cell non-Hodgkin lymphoma (NHL). The current study was the registration trial and the first reported evaluation of the efficacy, safety, and pharmacokinetics of bendamustine in Chinese adult patients with indolent B-cell NHL following relapse after chemotherapy and rituximab treatment. METHODS: This was a prospective, multicenter, open-label, single-arm, phase 3 study (NCT01596621; C18083/3076) with a 2-year follow-up period. Eligible patients received bendamustine hydrochloride 120âmg/m2 infused intravenously on days 1 and 2 of each 21-day treatment cycle for at least six planned cycles (and up to eight cycles). The primary endpoint was the overall response rate (ORR); and secondary endpoints were duration of response (DoR), progression-free survival (PFS), safety, and pharmacokinetics. Patients were classified according to their best overall response after initiation of therapy. Proportions of patients in each response category (complete response [CR], partial response [PR], stable disease, or progressive disease) were summarized along with a two-sided binomial exact 95% confidence intervals (CIs) for the ORR. RESULTS: A total of 102 patients were enrolled from 20 centers between August 6th, 2012, and June 18th, 2015. At the time of the primary analysis, the ORR was 73% (95% CI: 63%-81%) per Independent Review Committee (IRC) including 19% CR and 54% PR. With the follow-up period, the median DoR was 16.2âmonths by IRC and 13.4âmonths by investigator assessment; the median PFS was 18.6âmonths and 15.3âmonths, respectively. The most common non-hematologic adverse events (AEs) were gastrointestinal toxicity, pyrexia, and rash. Grade 3/4 neutropenia was reported in 76% of patients. Serious AEs were reported in 29 patients and five patients died during the study. Pharmacokinetic analysis indicated that the characteristics of bendamustine and its metabolites M3 and M4 were generally consistent with those reported for other ethnicities. CONCLUSION: Bendamustine is an active and effective therapy in Chinese patients with relapsed, indolent B-cell NHL, with a comparable risk/benefit relationship to that reported in North American patients.

BACKGROUND: Extensive-stage small cell lung cancer (ES-SCLC) is deemed as a fatal malignancy with a poor prognosis. Although immunotherapy has gradually played an important role in the treatment of ES-SCLC since 2018, ES-SCLC treatment data and patient outcome before 2018, when chemotherapy served as a fundamental therapeutic strategy, is still meaningful as a summary of the situation regarding previous medical treatment and is a baseline for comparative data. In addition, the prognostic factors of ES-SCLC have failed to reach a consensus until now. Therefore, this study aimed to evaluate survival and identify the prognostic factors in an ES-SCLC population. METHODS: We retrospectively collected the detailed medical records of 358 patients with ES-SCLC from January 1, 2011 to December 31, 2018 in a Chinese top-level cancer hospital. The prognostic factors were evaluated by Cox univariate and multivariate analysis. RESULTS: The median overall survival (OS) of ES-SCLC patients (N = 358) was 14.0 months, the one- and two-year OS rates were 56.2% and 21.7%, respectively. Moreover, we identified two demographic characters (age ≥ 70, smoking index ≥ 400), one tumor burden factor (bone multimetastasis), two tumor biomarkers (cyfra211, CA125) and two laboratory indexes (decreased Na, PLR < 76) as independent prognostic factors for OS in this patient population. Progression-free survival (PFS) data of 238 patients was obtained for further analysis, and the median PFS was 6.2 months, and six-month and one-year PFS rates were 51.7% and 14.3%, respectively. Elevated cyfra211, decreased Hb and Na were identified as independent prognostic factors for PFS. CONCLUSIONS: This study provides real-world evidence of the survival and prognosis of ES-SCLC patients which will enable better evaluation and clinical decision-making in the future.

IMPORTANCE: Plinabulin is a novel, non-granulocyte colony-stimulating factor (GCSF) small molecule with both anticancer and neutropenia-prevention effects. OBJECTIVE: To assess the efficacy and safety of plinabulin compared with pegfilgrastim for the prevention of chemotherapy-induced neutropenia following docetaxel chemotherapy in patients with non-small lung cancer. DESIGN, SETTING, AND PARTICIPANTS: This was a randomized, open-label, phase 2 clinical trial of 4 treatment arms that was conducted in 19 cancer treatment centers in the United States, China, Russia, and Ukraine. Participants were adult patients with non-small cell lung cancer whose cancer had progressed after platinum-based chemotherapy. Data were collected from April 2017 through March 2018 and analyzed from August 2019 through February 2020. INTERVENTIONS: All patients received docetaxel 75 mg/m2 on day 1 and were randomly assigned to 1 of 3 doses of plinabulin (5, 10, or 20 mg/m2) on day 1 or to pegfilgrastim 6 mg on day 2. Patients were treated every 21 days for 4 chemotherapy cycles. MAIN OUTCOMES AND MEASURES: The primary end point was the determination of the recommended phase 3 dose of plinabulin based on the days of severe neutropenia during chemotherapy cycle 1. Daily complete blood cell counts and absolute neutrophil counts were drawn during times of anticipated neutropenia during cycle 1. RESULTS: Of the 55 patients randomized and evaluated, the mean (SD) age was 61.3 (10.2) years, and 38 (69.1%) were men. With each escalation of the plinabulin dose, the incidence of any grade of neutropenia decreased. There were no significant differences in mean (SD) days of severe neutropenia among those treated with pegfilgrastim (0.15 [0.38] days) when dosed at day 2 vs plinabulin 20 mg/m2 (0.36 [0.93] days; P = .76) when dosed at day 1, and no safety signals were detected. CONCLUSIONS AND RELEVANCE: Single dose-per-cycle plinabulin has a similar neutropenia protection benefit as pegfilgrastim. Plinabulin 40 mg fixed dose, which is pharmacologically equivalent to 20 mg/m2, will be compared with pegfilgrastim 6 mg in the phase 3 portion of this trial. Noninferior days of severe neutropenia will be the primary end point, and bone pain reduction, thrombocytopenia reduction, and quality of life maintenance will be secondary end points.

The efficacy and possible role of epidermal growth factor receptor tyrosine kinase inhibitors in treating early-stage non-small-cell lung cancer have yet to be established. Therefore, we aimed to explore the efficacy and safety of icotinib in completely resected EGFR-mutant stage II-IIIA lung adenocarcinoma patients who underwent standard chemotherapy. This is a randomised, double-blinded, placebo-controlled, multicentre, Phase III trial. A total of 124 patients aged 18-75 years who qualified the inclusion criteria were recruited. These patients were randomised (1:1) to receive either icotinib (125 mg 3 times per day) or placebo (the same dosage and frequency) for 36 months, followed by a further 36 months of observational window. The primary endpoint is disease-free survival (DFS), while the secondary endpoints are overall survival, 3-year and 5-year DFS, safety and tolerability of the medication, and health-related quality-of-life. Analyses will be conducted in a full analysis set and a per-protocol set as well. To our knowledge, the present study is the first randomised, double-blinded, placebo-controlled, multicenter trial designed to explore efficacy and safety of icotonib in this population. The results obtained in the near future may provide potential guidance in clinical practice. Trial Registration: This trial was registered on www.ClinicalTrail.gov as NCT02125240.
ABSTRACT
Background: Response Evaluation Criteria in Solid Tumors (RECIST) has been widely utilized to evaluate new therapeutic strategies in cancer. However, RECIST fails to assess the heterogeneity of response in highly active therapies. Depth of response (DepOR), defined as the maximum percentage change in tumor size compared with baseline, may provide a new strategy to evaluate disease response. In the present study, we studied the association between DepOR and progression-free survival (PFS) in patients with advanced non-small cell lung cancer (NSCLC) treated with epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI). Methods: Advanced NSCLC patients harboring EGFR driver mutation (L858R or exon 19 deletion) treated with EGFR-TKI from August 2014 to July 2017 from two sites were retrospetively collected for analysis. Patients were divided into four groups by DepOR (Q1 = 1-25%, Q2 = 26-50%, Q3 = 51-75%, Q4 = 76-100%). Kaplan-Meier curves were plotted for PFS against DepOR and the hazard ratio (HR) was determined through univariable and multivariable cox regression models. Results: In total, 265 patients were included for analysis. The number of patients in Group Q1-Q4 were 91 (34.3%), 73 (27.5%), 65 (24.5%) and 36 (13.6%), respectively. A greater DepOR was significantly associated with a longer PFS (Log-rank P<0.0001). The HRs (95% CI) for PFS comparing patients with different DepOR status were 0.58 (0.42-0.80) for Q2, 0.49 (0.35-0.69) for Q3, and 0.33 (0.22-0.50) for Q4, all compared with patients in Q1. DepOR as a continuous variable was also associated with prolonged PFS (HR, 0.20; 95% CI, 0.13-0.33; P<0.001). Additionally, in the multivariable cox regression model, abnormal LDH, brain metastasis and male were found to be associated with worse PFS outcomes (P<0.05). Conclusion: A greater DepOR is significantly associated with PFS benefit in advanced NSCLC treated with EGFR-TKI, suggesting that it may be a useful clinical outcome to evaluate the response of targeted therapy.
ABSTRACT
BACKGROUND: Elderly patients with diffuse large B-cell lymphoma (DLBCL) have a worse prognosis than younger patients, and the optimal treatment strategy for this group remains controversial. We conducted a retrospective analysis to investigate the clinical features and outcomes of elderly patients (>60 years) and to assess the impact of clinical and molecular factors on outcome in this age group. METHODS: From April 2006 to December 2012, a total of 349 elderly patients with DLBCL from the National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences, and Peking Union Medical College were included in this analysis. Patients were further divided into two age groups (61-69 years and ≥70 years). We compared clinical characteristics and outcomes between groups. RESULTS: Of 349 total patients, 204 (58.5%) were aged 61 to 69 years, and 145 (41.5%) patients were aged 70 years or older. Except for the Eastern Cooperative Oncology Group performance status, clinical characteristics were comparable between the two groups. With a median follow-up of 82 (range, 1-129) months, the 5-year overall survival (OS) and progression-free survival (PFS) rates were 51.9% and 45.8%, respectively. The 5-year OS rates for patients aged 61 to 69 years and those over 70 years were 58.3% and 42.8% (Pâ=â0.007), respectively, and the 5-year PFS rates were 51.0% and 38.6% (Pâ=â0.034). Treatment regimens including rituximab provided a higher 5-year OS rate (63.1% vs. 37.1%, Pâ<â0.001) and PFS rate (56.6% vs. 31.8%, Pâ<â0.001) than chemotherapy alone. For patients aged 61 to 69 years, chemotherapy plus rituximab resulted in a higher 5-year OS rate (66.7% vs. 46.4%, Pâ=â0.002) and PFS rate (60.0% vs. 38.1%, Pâ=â0.002) than chemotherapy alone. For patients aged ≥70 years, there was a marked survival advantage in patients who received chemotherapy plus rituximab (5-year OS rate: 57.7% vs. 25.4%, Pâ<â0.001; 5-year PFS rate: 51.3% vs. 23.9%, Pâ<â0.001) compared with that seen in those who received chemotherapy alone. Multivariate analysis established that stage III/IV disease, elevated lactate dehydrogenase (LDH), initial treatment, and chemotherapy with rituximab were independent risk factors for 5-year OS, and stage III/IV disease, elevated LDH, and chemotherapy with rituximab were independent risk factors for 5-year PFS for elderly patients with DLBCL. CONCLUSIONS: In comparison to patients aged 61 to 69 years, those aged ≥70 years have poorer survival. Prolonged survival is obtainable with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP)-like in elderly Chinese patients in all age groups, indicating that the R-CHOP-like regimen should be considered for this population, even for those aged 70 years or older.

BACKGROUND: Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have become important treatment options for non-small cell lung cancer (NSCLC) patients with EGFR sensitive mutation. However, the detection of EGFR driver mutation is impeded by the lack of adequate tumor tissues, histopathological type, long detection period, and the heterogeneity of a tumor. Therefore, it is necessary to develop a more convenient method to guide the clinical use of EGFR-TKI. Circular RNAs (circRNAs) are characterized as a closed structure with covalently joined ends resistant to exonucleases may be a potential biomarker. In the present study, we aimed to screen circRNAs that may be associated with the efficacy of EGFR-TKI. METHODS: The expression of circRNAs sequenced by circular microarray in plasma samples between gefitinib effective and ineffective groups were compared. RT-qPCR further validated the results in an independent cohort. Kaplan-Meier curves were used to analyze the association between circRNA and progression-free survival (PFS) of NSCLC patients treated with gefitinib. RESULTS: In total, 52 NSCLC patients treated with gefitinib were included for analysis. 1,377 circRNAs were differentially expressed in gefitinib effective and ineffective groups, among which 989 circRNAs were up-regulated, and 388 circRNAs were down-regulated in the effective group. Furthermore, two differentially expressed circRNAs, hsa_circ_0109320 and hsa_circ_0134501, were validated by RT-qPCR in an independent cohort of 38 gefitinib-treated NSCLC patients. Elevated hsa_circ_0109320 was associated with longer PFS in gefitinib-treated NSCLC patients. CONCLUSIONS: Taken together, hsa_circ_0109320 may be a potential biomarker for the efficacy of EGFR-TKI in NSCLC patients. This provides a new molecular typing method for individualized precision treatment.
ABSTRACT
Purpose: The aim of this phase Ib study (clinicaltrials.gov: NCT01772732) was to assess safety, tolerability, and pharmacokinetics (PKs) of simotinib (a novel EGFR tyrosine kinase inhibitor) in patients with advanced non-small cell lung cancer (NSCLC) and EGFR gene mutation. Patients and methods: 41 patients with EGFR gene mutations were enrolled and received simotinib orally administered twice daily with dose escalating from 100 to 650 mg in 28 days cycle. Safety and tolerability were assessed through the study. Blood samples were collected for PK analysis on Days 1, 8, 9, 10, 15, 22 and 29. Tumor response was assessed at baseline, on Day 29 and every 8 weeks thereafter. Results: Simotinib was well tolerated, with no dose-limiting toxicities. Maximum tolerated dose (MTD) was not found. 95.1% of patients experienced at least one adverse event (AE), and most of them were mild or moderate. Rash (41.5%) and diarrhea (56.1%) were the most frequently reported AEs. Simotinib was rapidly absorbed and eliminated with average T max ranging from 1 to 4 hrs and T 1/2 ranging between 6.2 and 13.0 hrs after multiple-dose administration. No dose-response relationship between dose and exposure was observed after multiple-dose administration. 39.3% of the enrolled patients achieved a partial response and 46.3% had stable disease. Median progression-free survival and overall survival were 9.9 (CI% 4.7; 12.1) months and 14.6 (95%CI 12.3; 22.5) months, respectively. Conclusion: Simotinib was well tolerated, with manageable AEs at doses of up to 650 mg and MTD was not reached. Further studies to explore higher doses are ongoing.

INTRODUCTION: The phase III randomized PROFILE 1014 study demonstrated superiority of crizotinib to first-line chemotherapy in prolonging progression-free survival (PFS) in previously untreated patients with ALK receptor tyrosine kinase gene (ALK)-positive advanced nonsquamous NSCLC. This result was consistent with that in the smaller subset of East Asian patients in PROFILE 1014. The subsequent study reported here prospectively evaluated crizotinib in a larger East Asian patient population. METHODS: In this open-label phase III study (PROFILE 1029), patients were randomized 1:1 to receive orally administered crizotinib 250 mg twice daily continuously (3-week cycles) or intravenously administered chemotherapy (pemetrexed 500 mg/m2, plus cisplatin 75 mg/m2, or carboplatin [at a dose to produce area under the concentration-time curve of 5-6 mg·min/mL]) every 3 weeks for a maximum of six cycles. PFS confirmed by independent radiology review was the primary end point. RESULTS: Crizotinib significantly prolonged PFS (hazard ratio, 0.402; 95% confidence interval [CI]: 0.286-0.565; p < 0.001). The median PFS was 11.1 months with crizotinib and 6.8 months with chemotherapy. The objective response rate was 87.5% (95% CI: 79.6-93.2%) with crizotinib versus 45.6% (95% CI: 35.8-55.7%) with chemotherapy (p < 0.001). The most common adverse events were increased transaminase levels, diarrhea, and vision disorders with crizotinib and leukopenia, neutropenia, and anemia with chemotherapy. Significantly greater improvements from baseline in patient-reported outcomes were seen in crizotinib-treated versus chemotherapy-treated patients. CONCLUSIONS: First-line crizotinib significantly improved PFS, objective response rate, and patient-reported outcomes compared with standard platinum-based chemotherapy in East Asian patients with ALK-positive advanced NSCLC, which is similar to the results from PROFILE 1014. The safety profiles of crizotinib and chemotherapy were consistent with those previously published.

Purpose Rituximab (R) plus CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy is the standard of care in previously untreated diffuse large B-cell lymphoma (DLBCL). Obinutuzumab (G) is a glycoengineered, type II, anti-CD20 monoclonal antibody. GOYA was a randomized phase III study that compared G-CHOP with R-CHOP in patients with previously untreated advanced-stage DLBCL. Methods Patients (N = 1,418) were randomly assigned to receive eight 21-day cycles of G (n = 706) or R (n = 712), plus six or eight cycles of CHOP. Primary end point was investigator-assessed progression-free survival (PFS). Results After median observation of 29 months, the number of investigator-assessed PFS events was similar between G (201; 28.5%) and R (215; 30.2%), stratified hazard ratio was 0.92 (95% CI, 0.76 to 1.11; P = .39), and 3-year PFS rates were 70% and 67%, respectively. Secondary end points of independently reviewed PFS, other time-to-event end points, and tumor response rates were similar between arms. In exploratory subgroup analyses, patients with germinal-center B cell-like subtype had a better PFS than did patients with activated B cell-like subtype, irrespective of treatment. Frequencies of grade 3 to 5 adverse events (AEs; 73.7% v 64.7%, respectively) and serious AEs (42.6% v 37.6%, respectively) were higher with G-CHOP compared with R-CHOP. Fatal AE frequencies were 5.8% for G-CHOP and 4.3% for R-CHOP. The most common AEs were neutropenia (G-CHOP, 48.3%; R-CHOP, 40.7%), infusion-related reactions (G-CHOP, 36.1%; R-CHOP, 23.5%), nausea (G-CHOP, 29.4%; R-CHOP, 28.3%), and constipation (G-CHOP, 23.4%; R-CHOP, 24.5%). Conclusion G-CHOP did not improve PFS compared with R-CHOP in patients with previously untreated DLBCL. AEs reported with G were consistent with the known safety profile. Biomarker analyses may help define a future role for G in DLBCL.

BACKGROUND: The International Prognostic Score (IPS) was developed based on the data of Western advanced Hodgkin lymphoma (HL) patients treated before 1992. Only a few studies ever evaluated the application value of IPS in Chinese population or in patients treated in the contemporary era whose outcomes has improved significantly than before. METHODS: We conducted a retrospective study involving 208 previously untreated Chinese advanced HL patients, who were admitted to Cancer Hospital Chinese Academy of Medical Sciences from January 1, 1999 to April 30, 2015 and received uniform first-line treatment. The prognostic value of both IPS and the seven IPS factors for freedom-from progression (FFP) and overall survival (OS) was assessed in this population. The statistical methods included Kaplan-Meier methodology, log-rank testing, and Cox proportional hazard regression analysis. RESULTS: With a median follow-up time of 79 months (range, 15-210 months), the 5-year FFP and OS were 78.8% and 86.0% respectively, which improved obviously compared with the original IPS study. The IPS remained prognostic for both FFP (P = 0.041) and OS (P = 0.013), but the range narrowed obviously, with 5-year FFP ranging from 87.2% to 61.5%, 5-year OS ranging from 94.1% to 69.2%, and the separation of survival curves was not as good as before. Only two of the seven IPS factors showed a significant independent prognostic value in the multivariate analysis: Stage IV (for FFP, hazard ratio [HR] = 2.219, 95% confidence interval [CI]: 1.148-3.948, P = 0.016; for OS, HR = 2.491, 95% CI: 1.159-5.355, P = 0.019) and hemoglobin <105 g/L (for FFP, HR = 2.136, 95% CI: 1.123-4.060, P = 0.021; for OS, HR = 2.345, 95% CI: 1.099-5.042, P = 0.028). A simple prognostic score calculated by adding one point each for any of the two factors was prognostic both for FFP (P < 0.001) and OS (P < 0.001) with the survival curves separating very well, but the range still narrowed. CONCLUSIONS: The IPS has decreased the prognostic value in Chinese advanced HL patients treated in the contemporary era. More prognostic factors are needed to supplement this original scoring system so as to identify different risk populations more accurately.

BACKGROUND: To evaluate the antitumor activity and toxicity of icotinib as initial treatment in lung adenocarcinoma patients with brain metastases. METHODS: Twenty-one patients with histologically or pathologically documented brain metastatic lung cancer were administered icotinib as initial treatment from 2011 to 2015 at the Cancer Institute and Hospital, Chinese Academy of Medical Sciences. Chemotherapy response was assessed by Response Evaluation Criteria in Solid Tumors and toxicity was evaluated according to National Cancer Institute-Common Toxicity Criteria. Icotinib was administered three times per day at a dose of 125mg. RESULTS: The median overall and progression-free survival rates were 15.2 (1.2-31.5 months, 95% confidence interval [CI] 6.6-23.7 months) and 8.9 months (0.6-30.5 months, 95% CI 3.4-14.3 months), respectively. The overall response and disease control rates were 61.9% and 90.5%, respectively. Icotinib was well tolerated, and no grade 3/4 adverse events were observed. The most common grade 1/2 adverse events included acneiform eruptions (38.1%), diarrhea (19.0%), and stomatitis (9.5%). CONCLUSION: Icotinib is effective and well tolerated as initial treatment in lung adenocarcinoma patients with brain metastases.
ABSTRACT
This study aimed to assess the efficacy and safety of a combination of paclitaxel and cisplatin/carboplatin for the treatment of advanced thymic carcinoma. Thirty-seven patients (23 men and 14 women, median age 47 years, performance status score ≤2) with pathologically or cytologically diagnosed advanced thymic carcinoma were recruited. Patients received 175 mg/m(2) paclitaxel on day 1 and 75 mg/m(2) cisplatin or 300 mg/m(2) carboplatin on day 2 of a 21 day cycle for at least two cycles to evaluate efficacy and adverse events. No complete response (CR) was observed; 11 patients had a partial response (PR), 16 patients had no change (NC), and 10 had progressive disease, resulting in an overall response rate of 29.7%, a stable rate of 43.2%, and a disease control rate (CR + PR + NC) of 72.9%. Grade I/II and III/IV neutropenia were observed in 21 (56.7%) and 13 (35.1%) patients, respectively. Four (10.8%) patients developed grade I/II thrombocytopenia. Grade I/II and III/IV nausea and vomiting were observed in 19 (51.2%) and five (13.5%) patients, respectively. Grade I/II liver dysfunction was observed in seven (18.9%) patients. Two patients with grade III liver dysfunction recovered after hepatoprotective treatment. The combination of paclitaxel and platinum was effective and well tolerated in patients with advanced thymic carcinoma.
ABSTRACT
This study was conducted to evaluate the effectiveness and tolerance of GDP (gemcitabine, dexamethasone, and cisplatin) regimen in patients with newly diagnosed stage IV and relapsed/refractory extranodal natural killer/T-cell lymphoma, nasal type (ENKTL).The study enrolled 41 ENKTL patients who received GDP regimen at the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2008 and January 2015.The disease status was newly diagnosed stage IV in 15 patients and relapsed/refractory in 26 patients. The median number of cycles of chemotherapy per patient was 6 (range, 2-8 cycles). The overall response rate and complete-remission rate were 83.0% (34/41) and 41.5% (17/41), respectively. After a median follow-up of 16.2 months, 1-year progression-free survival rate and 1-year overall survival rate for the whole cohort were 54.5% and 72.7%. Grade 3 to 4 adverse events included neutropenia (34.1%), thrombocytopenia (19.5%), and anemia (14.6%).Our study has suggested high efficacy and low toxicity profile of GDP regimen in patients with newly diagnosed stage IV and relapsed/refractory ENKTL.

BACKGROUND: To compare the overall survival (OS) of patients with advanced lung adenocarcinoma in China before and after the approved use of gefitinib, and analyze clinical factors that may affect OS. METHODS: Clinical data of 558 patients with advanced lung adenocarcinoma who received chemotherapy from January 2002 to December 2010 were retrospectively analyzed. According to the matched-pair case-control study design, 255 patients who only received chemotherapy and 255 patients who received gefitinib treatment after its approval were stringently matched by age, gender, and smoking history and enrolled in the study. Clinical factors including age, gender, smoking history, Eastern Cooperative Oncology Group (ECOG) performance status (PS), tumor stage, organ metastasis, and the number of prior chemotherapies were analyzed to determine their correlations with OS. RESULTS: The median survival time (MST) of the 510 enrolled patients with advanced lung adenocarcinoma was 22.8 months. The MST of the patients who received gefitinib treatment was significantly longer than that of patients who did not receive gefitinib treatment (33.5 vs. 14.1 months, P < 0.001). The OS in patients who received gefitinib treatment was significantly longer than in patients who did not receive gefitinib treatment in almost all clinical factor-based subgroups, including age, gender, smoking history, ECOG PS 0-1, tumor stage, the presence or absence of lung, pleural, bone, brain, adrenal gland and liver metastasis, and the number of prior chemotherapies (all P < 0.001), except in the ECOG PS ≥2 subgroup. CONCLUSIONS: Gefitinib treatment significantly improved the survival of patients with advanced lung adenocarcinoma in China.
