Introduction
Long-term data on outcomes of operable stage III NSCLC are scarce.Methods
Individual patient data from 368 patients enrolled in one phase III and two phase II trials were pooled and outcomes after applying the eighth (denoted with an asterisk [*]) versus the sixth TNM staging edition were compared. Patients were treated with either preoperative radiotherapy following 3 cycles of induction chemotherapy (trimodal) or neoadjuvant chemotherapy alone (bimodal).Results
With the sixth version, the 5- and 10-year survival rates were 38% and 28% for stage IIIA, respectively, and 36% and 24% for stage IIIB, respectively. Factors associated with improved 5-year overall survival were younger age, R0 resection, and pathologic complete remission (pCR) (p = 0.043, p < 0.001 and p = 0.009). With the eighth TNM staging version, 162 patients were moved from stage IIIA to IIIB*. The 5- and 10-year survival rates were 41% and 29% for stage IIIA*, respectively, and 35% and 27% for stage IIIB* patients, respectively. There was no difference in the bi- versus trimodal group with regard to median overall survival (28 months [95% confidence interval (CI): 21–39 months] and 37 months [95% CI: 24–51 months], p = 0.9) and event-free survival (12 months [95% CI: 9–15 months] versus 13 months [95% CI: 10–22 months], p = 0.71).Conclusions
We showed favorable 10-year survival rates of 29% and 27% in stage IIIA* and IIIB*, respectively. Younger age, R0 resection, and pathologic complete response were associated with improved long-term survival. Outcomes using the sixth versus eighth edition of the TNM classification were similar in operable stage III NSCLC. 相似文献Background
Orbital rhabdomyosarcoma (ORMS) commonly presents as low-risk disease (stage 1, group I–III, embryonal RMS) with excellent outcome. Long-term follow-up of patients with low-risk ORMS and outcomes of less common subgroups of ORMS treated on recent Children's Oncology Group (COG) trials have not been reported.Methods
Patients with ORMS enrolled on COG trials from 1997 to 2013 were identified. Demographic information and disease characteristics were collected. Outcomes were determined for the following subgroups: 1) low-risk ORMS, 2) resected (group I/II) low-risk ORMS, 3) non–low-risk ORMS, and 4) recurrent ORMS. Event-free survival (EFS) and overall survival (OS) were estimated using the Kaplan–Meier method. ResultsThe authors identified 218 patients with ORMS. Most tumors were embryonal/botryoid (n = 169; 77.5%), <5 cm (n = 213; 97.7%), group III (n = 170; 78.0%), and without lymph node involvement (N0; n = 215; 98.6%). For 192 patients with low-risk ORMS, the 10-year EFS and OS rates were 85.5% (95% confidence interval [CI], 77.0%–94.0%) and 95.6% (95% CI, 90.8%–100.0%), respectively. Those with group I/II low-risk ORMS (n = 5 in group I; n = 39 in group IIA) had 10-year EFS and OS rates of 88.0% (95% CI, 72.6%–100.0%) and 97.6% (95% CI, 90.0%–100.0%), respectively. Twenty-six patients with non–low-risk ORMS had 5-year EFS and OS rates of 88.5% (95% CI, 75.6%–100.0%) and 95.8% (95% CI, 87.7%–100.0%), respectively. For patients with recurrent ORMS, the 10-year OS rate from the time of recurrence was 69.4% (95% CI, 50.0%–88.8%).Conclusions
Patients with ORMS had favorable long-term survival outcomes on COG studies from 1997 to 2013, including those who had both low-risk and non–low-risk disease. A significant proportion of patients with recurrent ORMS may achieve long-term survival. 相似文献Background
The objective of this study was to evaluate the safety and efficacy of nab-paclitaxel, trastuzumab, and pertuzumab as neoadjuvant therapy (NAT) in patients with human epidermal growth factor receptor 2 HER2+ breast cancer (HER2+ BC) to determine pathologic complete response (pCR), invasive disease-free survival (iDFS), and overall survival.Methods
Forty-five patients with HER2+ BC Stages II–III were to be enrolled from 2013 to 2017. Patients were treated with weekly nab-paclitaxel (100 mg/m2 intravenously), weekly trastuzumab (4 mg/kg loading dose, then 2 mg/kg), and six cycles of pertuzumab (840 mg loading dose, then 420 mg intravenously day 1 every 21 days).Results
Median follow-up was 60 months (95% CI, 32.3–55.6) and pCR was 29/45 (64%). The 5-year iDFS for patients who achieved pCR (N = 29) was 96.3% (95% CI, 76.5–99.5) and non-pCR patients (N = 16) was 74.3% (95% CI, 39.1–91.0). The 5-year overall survival (N = 45) was 94.1% (95% CI, 77.6–98.5). Based on hormonal status, the 5-year iDFS for HR+ pCR patients (N = 14) was 92.3% (95% CI, 56.6–98.9) and for HR− (N = 15) was 100% (p = .3).Conclusions
This anthracycline/carboplatin-free regimen with nab-paclitaxel achieved a pCR rate of 64% in patients with HER2+ BC. The 5-year iDFS in patients with and without pCR was 96.3% and 74.3%, respectively. The pCR rate is comparable with docetaxel, carboplatin, trastuzumab, and pertuzumab therapy in the NAT setting, but with fewer treatment-associated toxicities. This finding suggests the possibility of safe avoidance of anthracyclines and carboplatin as components of NAT in patients with HER2+ BC. 相似文献Background
This study compares survival rates, recurrence patterns, toxicity, and treatment cost in patients with hepatocellular carcinoma (HCC) treated with either transarterial chemoembolization (TACE) or proton beam radiotherapy (PBT).Methods
Subjects with untreated HCC meeting Milan or San Francisco transplant criteria were recruited. Subjects were randomized to receive PBT (n = 36) or TACE (n = 40). Proton therapy was administered in 15 fractions over 3 weeks to a total dose of 70.2 Gy. TACE was repeated until complete or maximal response. The primary outcome measure was overall survival (OS). Secondary end points were progression-free survival (PFS), local control (LC), toxicity, and cost.Results
Of the 76 randomized patients, 74 were assessed for outcome measures. The 2-year OS for PBT versus TACE was similar at 68%, 95% confidence interval (CI), 0.54–0.86, and 65%, 95% CI, 0.52–0.83 (p = .80), however, median PFS was improved for PBT versus TACE (not reached vs. 12 months, p = .002). LC was improved with PBT versus TACE (hazard ratio, 5.64; 95% CI, 1.78–17.9, p = .003). Days of posttreatment hospitalization were 24 for PBT and 166 for TACE (p < .001). Total mean cost per patient for treatment and posttreatment care revealed a 28% cost savings for PBT.Conclusions
PBT and TACE yielded similar OS for treatment of HCC, but PFS and LC were improved with PBT compared to TACE. Patients treated with PBT required fewer courses of treatment, fewer posttreatment hospitalization days, and reduced cost of treatment compared to TACE. These data support the use of PBT as a viable treatment alternative to TACE for patients with HCC within transplant criteria. 相似文献Background
A lower baseline bone marrow blast percentage (bBMB%) is associated with better outcomes in patients with B-cell acute lymphoblastic leukemia (B-ALL) receiving blinatumomab. The objective of this analysis was to investigate the association between bBMB% and treatment outcomes in relapsed/refractory (R/R) B-ALL.Methods
Data from five trials of blinatumomab for R/R B-ALL were pooled for analyses. Patients were placed in one of three groups: group 1, ≥50% bBMBs; group 2, ≥25% to <50% bBMBs; group 3, ≥5% to <25% bBMBs. Response and survival outcomes were compared between groups.Results
Data from 683 patients (166 pediatric, 517 adult) were analyzed. Collectively, patients in groups 2 and 3 had significantly higher odds of achieving a complete remission (CR) (odds ratio [OR], 3.50 [95% confidence interval (CI), 2.23–5.48] and 3.93 [95% CI, 2.50–6.18], respectively; p < .001) and minimal/measurable residual disease response (OR, 2.61 and 3.37, respectively; p < .001) when compared with group 1 (reference). Groups 2 and 3 had a 37% and 46% reduction in the risk of death (hazard ratio [HR], 0.63 and 0.54, respectively; p < .001) and a 41% and 43% reduction in the risk of an event (relapse or death) (HR, 0.59 and 0.57, respectively; p < .001) compared with group 1. No significant differences in response or survival outcomes were observed between groups 2 and 3. Seven of nine patients whose bBMB% was lowered to <50% with dexamethasone achieved CR with blinatumomab.Conclusion
Any bBMB% <50% was associated with improved efficacy following blinatumomab treatment for R/R B-ALL. 相似文献Introduction
The role of prophylactic cranial irradiation (PCI) is controversial in patients with extensive stage small cell lung cancer. The aim of this study was to determine the impact of PCI in these patients.Methods
We performed a systematic review and meta-analysis in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A systematic literature search was conducted in MEDLINE, EMBASE, and the Cochrane Central Register. The primary outcome was overall survival (OS).Results
We identified five studies comprising 984 patients, of whom 448 received PCI and 536 did not receive PCI. In pooled estimates, PCI did not statistically improve OS compared with controls (hazard ratio [HR] = 0.82; 95% confidence interval [CI]: 0.60–1.11; I2 = 77%; p = 0.19). However, the PCI group had a significant advantage in 1-year survival compared to the no-PCI group (37.1% versus 27.1%; risk ratio = 0.87; 95% CI: 0.80–0.95; I2 = 47%; p = 0.002), and the pooled estimates indicated that progression-free survival and the risk of brain metastasis were associated with significant benefit in the PCI group (HR = 0.83; 95% CI: 0.70–0.98; I2 = 22%; p = 0.03; and HR = 0.34; 95% CI: 0.23–0.50; I2 = 0%; p < 0.001, respectively).Conclusions
Our findings suggest that PCI in patients with extensive stage small cell lung cancer may lead to a significant benefit in 1-year survival, progression-free survival, and the risk of brain metastasis, despite the lack of a significant advantage in OS. 相似文献Surgery is becoming more practical and effective than conservative treatment in improving the poor outcomes of patients with breast cancer liver metastasis (BCLM). However, there is no generally acknowledged set of standards for identifying BCLM candidates who will benefit from surgery.
MethodsBetween January 2011 and September 2018, 67 female BCLM patients who underwent partial hepatectomy were selected for analysis in the present study. Prognostic factors after hepatectomy were determined. Univariate and multivariate analyses were performed to identify predictors of overall survival (OS) and intrahepatic recurrence-free survival (IHRFS).
ResultsThe 1-, 3- and 5-year OS of patients treated with surgery was 93.5%, 73.7% and 32.2%, respectively, with a median survival time of 57.59 months. The Pringle manoeuvre [hazard radio (HR)?=?0.117, 95% CI0.015–0.942, p?=?0.044] and an increased interval between breast surgery and BCLM diagnosis (HR0.178, 95% CI 0.037–0.869, p?=?0.033) independently predicted improved overall survival for BCLM patients. The 1-, 2- and 3-year IHRFS of patients who underwent surgery was 62.8, 32.6% and 10.9%, respectively, with a median intrahepatic recurrence-free survival time of 13.47 months. Moderately differentiated tumours (HR ?0.259, 95% CI 0.078–0.857, p?=?0.027) and the development of liver metastasis more than 2 years after breast surgery (HR ?0.270, 95% CI 0.108–0.675, p?=?0.005) might be predictors of increased IHRFS.
ConclusionsAn interval of more than 2 years between breast cancer surgery and liver metastasis seems to be an indication of liver surgery in BCLM patients. The Pringle manoeuvre and moderately differentiated tumours are potential predictors associated with OS and IHRFS, respectively, as benefits from liver resection. Studies with increased sample sizes are warranted to validate our results.

The PRIMA/ENGOT-OV26/GOG-3012 (NCT02655016) trial was amended to prospectively evaluate the safety and efficacy of an individualized starting dose (ISD) regimen of niraparib for first-line maintenance therapy in patients with newly diagnosed advanced ovarian cancer.Methods
In the phase 3 PRIMA trial, patients with newly diagnosed advanced ovarian cancer with a complete/partial response to first-line platinum-based chemotherapy (N = 733) were initially treated with a fixed starting dose (FSD) regimen of 300 mg once daily. Subsequently, the protocol was amended so newly enrolled patients received an ISD: 200 mg once daily in patients with baseline body weight < 77 kg or baseline platelet count < 150,000/µL, and 300 mg once daily in all other patients. Efficacy and safety outcomes were assessed by starting dose.Results
Overall, 475 (64.8%) patients were assigned to an FSD (niraparib, n = 317; placebo, n = 158) and 258 (35.2%) were assigned to an ISD (niraparib, n = 170; placebo, n = 88). Efficacy in patients who received FSD or ISD was similar for the overall (FSD hazard ratio [HR], 0.59 [95% CI, 0.46–0.76] vs. ISD HR, 0.69 [95% CI, 0.48–0.98]) and the homologous recombination–deficient (FSD HR, 0.44 [95% CI, 0.30–0.64] vs. ISD HR, 0.39 [95% CI, 0.22–0.72]) populations. In patients with low body weight/platelet count, rates of grades ≥3 and 4 hematologic treatment-emergent adverse events, dose interruptions, and dose reductions were lower for those who received ISD than for those who received FSD.Conclusions
In PRIMA, similar dose intensity, similar efficacy, and improved safety were observed with the ISD compared with the FSD regimen. 相似文献Background
Initial experiences with robotic gastrectomy (RG) for gastric cancer have demonstrated favorable short-term outcomes, suggesting that RG is an effective alternative to laparoscopic gastrectomy (LG). However, data on long-term survival and recurrence after RG for gastric cancer have yet to be reported. The objective of this study was to assess long-term outcomes after RG compared with LG.Methods
We retrospectively evaluated 313 and 524 patients who underwent RG or LG, respectively, for gastric cancer between July 2005 and December 2009. We compared long-term outcomes using the entire and a propensity-score matched cohort.Results
The entire cohort analysis revealed no statistically significant differences in 5-year overall survival(OS) or relapse-free survival(RFS) (p = 0.4112 and p = 0.8733, respectively): 93.3% [95% confidence interval (CI) 89.9–95.6] and 90.7% (95% CI, 86.9–93.5) after RG and 91.6% (95% CI 88.9–93.7) and 90.5% (95% CI 87.6–92.7) after LG, respectively; hazard ratios for death and recurrence in the robotic group were 0.828 (95% CI, 0.528–1.299; p = 0.4119) and 0.968 (95% CI, 0.649–1.445; p = 0.8741), respectively. The propensity-matched cohort analysis demonstrated no statistically significant differences for 5-year OS or RFS (p = 0.5207 and p = 0.2293, respectively): 93.2% and 90.7% after RG and 94.2% and 92.6% after LG, respectively; hazard ratios for death and recurrence in the robotic group were 1.194 (95% CI, 0.695–2.062; p = 0.5214) and 1.343 (95% CI, 0.830–2.192; p = 0.2321), respectively.Conclusion
The potential technical superiority of robotic system over laparoscopy did not improve oncological outcomes after gastrectomy. Long-term oncological outcomes were not different between RG and LG. Nevertheless, robotic applications in minimally invasive gastric cancer surgery may be an oncologically safe alternative.Background
EMPOWER-Lung 3, a randomized 2:1 phase 3 trial, showed clinically meaningful and statistically significant overall survival improvement with cemiplimab plus platinum-doublet chemotherapy versus placebo plus chemotherapy for first-line treatment of advanced non–small cell lung cancer. This study evaluated patient-reported outcomes (PROs).Methods
PROs were assessed at day 1 (baseline), the start of each treatment cycle (every 3 weeks) for the first six doses, and then at start of every three cycles, using the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life-Core 30 (QLQ-C30) and Quality of Life-Lung Cancer Module (QLQ-LC13) questionnaires. Prespecified analyses included a longitudinal mixed-effect model comparing treatment arms and a time to definitive clinically meaningful deterioration (TTD) analysis performed for global health status/quality of life (GHS/QoL) and all scales from the questionnaires. Between-arm TTD comparisons were made using a stratified log-rank test and proportional hazards model.Results
A total of 312 patients were assigned to receive cemiplimab plus platinum-doublet chemotherapy and 154 to receive placebo plus chemotherapy; 391 (83.9%) were male and the median age was 63.0 years (range, 25–84). For pain symptoms (EORTC QLQ-C30), a statistically significant overall improvement from baseline (−4.98, 95% confidence interval [CI] −8.36 to −1.60, p = .004) and a statistically significant delay in TTD (hazard ratio, 0.39; 95% CI, 0.26–0.60, p < .0001) favoring cemiplimab plus chemotherapy were observed. Statistically significant delays in TTD, all favoring cemiplimab plus chemotherapy, were also observed in functioning and symptom scales. A significant overall improvement from baseline in GHS/QoL was seen for cemiplimab plus chemotherapy compared with nonsignificant overall change from baseline for placebo plus chemotherapy (1.69, 95% CI, 0.20–3.19 vs. 1.08, 95% CI, –1.34 to 3.51; between arms, p = .673). No analyses yielded statistically significant PRO results favoring placebo plus chemotherapy for any QLQ-C30 or QLQ-LC13 scale.Conclusion
Cemiplimab plus chemotherapy resulted in significant overall improvement in pain symptoms and delayed TTD in cancer-related and lung cancer–specific symptoms and functions. 相似文献Background
Treatment options for refractory metastatic colorectal cancer (mCRC) were limited. Anlotinib is a novel multitarget tyrosine kinase inhibitor. ALTER0703 study was conducted to assess efficacy and safety of anlotinib for patients with refractory mCRC.Materials and Methods
This was a multicenter, double-blinded, placebo-controlled, randomized phase III trial involving 33 hospitals in China. Patients had taken at least two lines of therapies were 2:1 randomized to receive oral anlotinib (12 mg/day; days 1–14; 21 days per cycle) or placebo, plus best supportive care. Randomization was stratified by previous VEGF-targeting treatments and time from diagnosis to metastases. The primary endpoint was overall survival (OS). The secondary endpoints were progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), quality of life (QoL), and safety.Results
A total of 419 patients (anlotinib: 282; placebo: 137) were treated from December 2014 to August 2016. The median PFS was improved in anlotinib group (4.1 months; 95% confidence interval [CI], 3.4–4.5) over placebo group (1.5 months; 95% CI, 1.4–1.5), with a hazard ratio (HR) of 0.34 (95% CI, 0.27–0.43; p < .0001). However, median OS was similar between two groups (8.6 months; 95% CI, 7.8–9.7 vs. 7.2 months; 95% CI, 6.2–8.8; HR, 1.02; p = .870). Improvements of ORR and DCR were observed in anlotinib over placebo. The most common grade ≥ 3 anlotinib related adverse events were hypertension (20.92%), increased γ-GT (7.09%), and hand-foot skin reaction (6.38%).Conclusion
Anlotinib was tolerated in Chinese patients with refractory mCRC. Although OS did not reach significant difference, anlotinib still provided clinical benefits by substantially prolonged PFS in these patients.Implications for Practice
In this randomized clinical trial that included 419 patients with refractory metastatic colorectal cancer, substantial prolonged in progression-free survival was noted in patients who received anlotinib compared with those given placebo. Improvements on objective response rate and disease control rate was also observed in anlotinib group. However, overall survival was similar between the two groups. In a word, in third-line or above treatment of Chinese patients with refractory metastatic colorectal cancer, anlotinib provided clinical benefit by significantly prolonged progression-free survival.Introduction
We conducted a randomized controlled study to compare the survival benefit of paclitaxel plus carboplatin and oral uracil-tegafur (UFT) as adjuvant chemotherapy in resected NSCLC.Methods
In an open-label multicenter trial, patients with pathological stage IB to IIIA NSCLC were randomized into a group receiving paclitaxel (175 mg/m2) plus carboplatin (area under the curve 5) every 3 weeks for four cycles (arm A) or a group receiving orally administered UFT (250 mg/m2) daily for 2 years (arm B). The primary and secondary end points were overall survival and relapse-free survival and toxicity, respectively.Results
Between November 2004 and November 2010, 402 patients from 40 institutions were included (201 in each arm). The median follow-up period was 6.5 years. The 5-year overall survival rate was 70% (95% confidential interval [CI]: 63–76] in arm A versus 73% (95% CI: 66–78) in arm B (hazard ratio = 0.92, 95% CI: 0.55–1.41, p = 0.69). There was no significant difference in the 5-year relapse-free survival rate between arms A and B (56% versus 57% [hazard ratio = 0.92, 95% CI: 0.63–1.34, p = 0.50]). Toxicities were well tolerated and there was no treatment-related death. Toxicities of any grade or grade 4 were significantly more frequent in the paclitaxel plus carboplatin group (95.7% and 22.1%, respectively) than in the UFT group (76.5% and 1.0%, respectively [p < 0.0001 in both]).Conclusions
As adjuvant chemotherapy, paclitaxel plus carboplatin was no better than UFT in terms of survival among patients with stage IB to IIIA NSCLC tumors who underwent complete resection (UMIN000000810). 相似文献Background
In a pooled analysis of the phase 3 Controlled Myelofibrosis Study With Oral JAK Inhibitor Treatment I (COMFORT-I) and COMFORT-II clinical trials, adult patients with intermediate-2 or high-risk myelofibrosis who received oral ruxolitinib at randomization or after crossover from placebo or best available therapy (BAT) had improved overall survival (OS).Methods
This post hoc analysis of pooled COMFORT data examined relevant disease outcomes based on the disease duration (≤12 or >12 months from diagnosis) before ruxolitinib initiation.Results
The analysis included 525 patients (ruxolitinib: ≤12 months, n = 84; >12 months, n = 216; placebo/BAT: ≤12 months, n = 66; >12 months, n = 159); the median age was 65.0–70.0 years. Fewer thrombocytopenia and anemia events were observed among patients who initiated ruxolitinib treatment earlier. At Weeks 24 and 48, the spleen volume response (SVR) was higher for patients who initiated ruxolitinib earlier (47.6% vs. 32.9% at Week 24, p = .0610; 44.0% vs. 26.9% at Week 48, p = .0149). In a multivariable analysis of factors associated with spleen volume reduction, a logistic regression model that controlled for confounding factors found that a significantly greater binary reduction was observed among patients with shorter versus longer disease duration (p = .022). At Week 240, OS was significantly improved among patients who initiated ruxolitinib earlier (63% [95% CI, 51%‒73%] vs. 57% [95% CI, 49%‒64%]; hazard ratio, 1.53; 95% CI, 1.01‒2.31; p = .0430). Regardless of disease duration, a longer OS was observed for patients who received ruxolitinib versus those who received placebo/BAT.Conclusions
These findings suggest that earlier ruxolitinib initiation for adult patients with intermediate-2 and high-risk myelofibrosis may improve clinical outcomes, including fewer cytopenia events, durable SVR, and prolonged OS.Plain Language Summary
- Patients with myelofibrosis, a bone marrow cancer, often do not live as long as the general population. These patients may also have an enlarged spleen and difficult symptoms such as fatigue.
- Two large clinical trials showed that patients treated with the drug ruxolitinib lived longer and had improved symptoms compared to those treated with placebo or other standard treatments.
- Here it was examined whether starting treatment with ruxolitinib earlier (i.e., within a year of diagnosis) provided benefits versus delaying treatment.
- Patients who received ruxolitinib within a year of diagnosis lived longer and experienced fewer disease symptoms than those whose treatment was delayed.
