Abstract
BACKGROUND To report our findings on quality of life (QoL) in a randomized phase II study to determine the optimal dose of 3-week cycle nab-paclitaxel (q3w nab-PTX) in patients with metastatic breast cancer (MBC). METHODS Patients with HER2-negative MBC were randomly assigned to three different doses of q3w nab-PTX (SD 260 mg/m2 vs. MD: 220 mg/m2 vs. LD 180 mg/m2). QoL was assessed at baseline and during the second, fourth and sixth courses of treatment using the Functional Assessment of Cancer Therapy-Taxane (FACT-Taxane), Cancer Fatigue Scale (CFS) and EuroQol 5-Dimension (EQ-5D). Comparisons were performed with mixed-model repeated measures (MMRM). RESULTS A total of 141 patients were enrolled in the parent study, and 136 (96%) (44, 45 and 47 in the SD, MD, and LD groups) were included in the analysis. MMRM analysis showed that the difference from the baseline FACT-Taxane trial outcome index at MD and LD were significantly higher than that at SD (MD vs. SD P < 0.001, LD vs. SD P < 0.001). Differences from baseline for FACT-Taxane total, physical and emotional well-being, and taxane subscale scores at MD and LD were also higher than at SD. The difference from baseline for the CFS score at LD was lower than at SD (P = 0.013) and those for EQ-5D utility scores at MD and LD were higher than at SD (MD vs. SD P = 0.011, LD vs. SD P < 0.001). CONCLUSION QoL of patients treated with 220 or 180 mg/m2 of q3w nab-PTX was significantly better than that of patients treated with 260 mg/m2. TRIAL REGISTRATION The protocol was registered at the website of the University Hospital Medical Information Network (UMIN), Japan (protocol ID: UMIN000015516), on 01/11/2014.

Abstract
BACKGROUND This study evaluated the association between early tumor response at 8 weeks, previously reported as a positive outcome prognosticator, and health-related quality of life (HRQOL) in advanced gastric cancer (AGC) patients enrolled in the ABSOLUTE trial. METHODS HRQOL was assessed using the EuroQol-5 Dimension (EQ-5D) utility index score in patients with complete response (CR) + partial response (PR) and progressive disease (PD) at 8 weeks, and time-to-deterioration (TtD) of the EQ-5D score, with the preset minimally important difference (MID) of 0.05, was compared between these populations. Among the enrolled patients, 143 and 160 patients were assessable in weekly solvent-based paclitaxel (Sb-PTX) arm and weekly nanoparticle albumin-bound paclitaxel (nab-PTX) arm, respectively. RESULTS Changes of the EQ-5D score from baseline to 8 weeks in the nab-PTX arm were 0.0009 and - 0.1229 in CR + PR and PD patients, respectively; the corresponding values for the Sb-PTX arm were - 0.0019 and - 0.1549. For both treatments, changes of the EQ-5D score from baseline at 8 weeks were significantly larger in patients with PD than in those with CR + PR. The median TtD was 3.9 and 2.2 months in patients with CR + PR and PD, respectively, for nab-PTX [hazard ratio (HR) = 0.595, 95% confidence interval (CI) 0.358-0.989]. For Sb-PTX, the corresponding values were 4.7 and 2.0 months (HR = 0.494, 95% CI 0.291-0.841). CONCLUSIONS Early tumor shrinkage was associated with maintained HRQOL in AGC patients on the second-line chemotherapy with taxanes.

Abstract
BACKGROUND NK105 is a novel nanoparticle drug delivery formulation that encapsulates paclitaxel (PTX) in polymeric micelles. We conducted an open-label phase III non-inferiority trial to compare the efficacy and safety of NK105 and PTX in metastatic or recurrent breast cancer. METHODS Patients were randomly assigned in a 1:1 ratio to receive either NK105 (65 mg/m2) or PTX (80 mg/m2) on days 1, 8 and 15 of a 28-day cycle. The primary endpoint was progression-free survival (PFS), with a non-inferiority margin of 1.215. RESULTS A total of 436 patients were randomised and 211 patients in each group were included in the efficacy analysis. The median PFS was 8.4 and 8.5 months for NK105 and PTX, respectively (adjusted hazard ratio: 1.255; 95% confidence interval: 0.989-1.592). The median overall survival and overall response rates were 31.2 vs. 36.2 months and 31.6% vs. 39.0%, respectively. The two groups exhibited similar safety profiles. The incidence of peripheral sensory neuropathy (PSN) was 1.4% vs. 7.5% (≥Grade 3) for NK105 and PTX, respectively. The patient-reported outcomes of PSN were significantly favourable for NK105 (P < 0.0001). CONCLUSIONS The primary endpoint was not met, but NK105 had a better PSN toxicity profile than PTX.

Abstract
BACKGROUND Malignant airway obstruction (MAO) occurs in 30% of patients with advanced-stage lung cancer, leading to debilitating dyspnea, cough, and hemoptysis. Other than recanalization of the airways, these patients lack long-lasting palliative therapy. The goal of this study was to determine the safety and feasibility of local injection of paclitaxel into the airway wall with a novel microinjection catheter. METHODS In this multicentered prospective trial, 23 patients with non-small cell lung cancer and MAO were enrolled from July 2014 through June 2016 to undergo rigid bronchoscopy with recanalization, followed by injection of 1.5 mg of paclitaxel with a novel injection catheter. Primary end points consisted of safety (adverse events, severe adverse events, and unanticipated adverse device effects) as well as feasibility (number of injections, injection success). Secondary end points consisted of airway patency improvement, quality of life metrics, and need for further interventions and/or stenting. RESULTS Nineteen patients underwent rigid bronchoscopy with successful recanalization and paclitaxel injection. There were no adverse events, severe adverse events, or unanticipated adverse device effects. There was an average of 3.4 injections given for a total dose of 1.5 mg of paclitaxel in all patients. There was significantly less stenosis postprocedure vs preprocedure (25%-50% vs 75%-90%; P < .001), which was unchanged at 6 weeks (25%-50%). None of the participants required further interventions or airway stenting. CONCLUSIONS The injection of paclitaxel after recanalization of MAO in patients with non-small cell lung cancer is safe and feasible, using a novel airway injection device.

Abstract
BACKGROUND Most patients with small-cell lung cancer (SCLC) have extensive-stage disease at presentation, and prognosis remains poor. Recently, immunotherapy has demonstrated clinical activity in extensive-stage SCLC (ES-SCLC). The CASPIAN trial assessed durvalumab, with or without tremelimumab, in combination with etoposide plus either cisplatin or carboplatin (platinum-etoposide) in treatment-naive patients with ES-SCLC. METHODS This randomised, open-label, phase 3 trial was done at 209 sites across 23 countries. Eligible patients were adults with untreated ES-SCLC, with WHO performance status 0 or 1 and measurable disease as per Response Evaluation Criteria in Solid Tumors, version 1.1. Patients were randomly assigned (in a 1:1:1 ratio) to durvalumab plus platinum-etoposide; durvalumab plus tremelimumab plus platinum-etoposide; or platinum-etoposide alone. All drugs were administered intravenously. Platinum-etoposide consisted of etoposide 80-100 mg/m2 on days 1-3 of each cycle with investigator's choice of either carboplatin area under the curve 5-6 mg/mL per min or cisplatin 75-80 mg/m2 (administered on day 1 of each cycle). Patients received up to four cycles of platinum-etoposide plus durvalumab 1500 mg with or without tremelimumab 75 mg every 3 weeks followed by maintenance durvalumab 1500 mg every 4 weeks in the immunotherapy groups and up to six cycles of platinum-etoposide every 3 weeks plus prophylactic cranial irradiation (investigator's discretion) in the platinum-etoposide group. The primary endpoint was overall survival in the intention-to-treat population. We report results for the durvalumab plus platinum-etoposide group versus the platinum-etoposide group from a planned interim analysis. Safety was assessed in all patients who received at least one dose of their assigned study treatment. This study is registered at ClinicalTrials.gov, NCT03043872, and is ongoing. FINDINGS Patients were enrolled between March 27, 2017, and May 29, 2018. 268 patients were allocated to the durvalumab plus platinum-etoposide group and 269 to the platinum-etoposide group. Durvalumab plus platinum-etoposide was associated with a significant improvement in overall survival, with a hazard ratio of 0·73 (95% CI 0·59-0·91; p=0·0047]); median overall survival was 13·0 months (95% CI 11·5-14·8) in the durvalumab plus platinum-etoposide group versus 10·3 months (9·3-11·2) in the platinum-etoposide group, with 34% (26·9-41·0) versus 25% (18·4-31·6) of patients alive at 18 months. Any-cause adverse events of grade 3 or 4 occurred in 163 (62%) of 265 treated patients in the durvalumab plus platinum-etoposide group and 166 (62%) of 266 in the platinum-etoposide group; adverse events leading to death occurred in 13 (5%) and 15 (6%) patients. INTERPRETATION First-line durvalumab plus platinum-etoposide significantly improved overall survival in patients with ES-SCLC versus a clinically relevant control group. Safety findings were consistent with the known safety profiles of all drugs received. FUNDING AstraZeneca.

Abstract
BACKGROUND Noninvasive biomarkers are needed to guide metastatic castration-resistant prostate cancer (mCRPC) treatment. OBJECTIVE To clinically qualify baseline and on-treatment cell-free DNA (cfDNA) concentrations as biomarkers of patient outcome following taxane chemotherapy. DESIGN, SETTING, AND PARTICIPANTS Blood for cfDNA analyses was prospectively collected from 571 mCRPC patients participating in two phase III clinical trials, FIRSTANA (NCT01308567) and PROSELICA (NCT01308580). Patients received docetaxel (75mg/m2) or cabazitaxel (20 or 25mg/m2) as first-line chemotherapy (FIRSTANA), and cabazitaxel (20 or 25mg/m2) as second-line chemotherapy (PROSELICA). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Associations between cfDNA concentration and prostate-specific antigen (PSA) response were tested using logistic regression models. Survival was estimated using Kaplan-Meier methods for cfDNA concentration grouped by quartile. Cox proportional hazard models, within each study, tested for associations with radiological progression-free survival (rPFS) and overall survival (OS), with multivariable analyses adjusting for baseline prognostic variables. Two-stage individual patient meta-analysis combined results for cfDNA concentrations for both studies. RESULTS AND LIMITATIONS In 2502 samples, baseline log10 cfDNA concentration correlated with known prognostic factors, shorter rPFS (hazard ratio [HR]=1.54; 95% confidence interval [CI]: 1.15-2.08; p=0.004), and shorter OS on taxane therapy (HR=1.53; 95% CI: 1.18-1.97; p=0.001). In multivariable analyses, baseline cfDNA concentration was an independent prognostic variable for rPFS and OS in both first- and second-line chemotherapy settings. Patients with a PSA response experienced a decline in log10 cfDNA concentrations during the first four cycles of treatment (per cycle -0.03; 95% CI: -0.044 to -0.009; p=0.003). Study limitations included the fact that blood sample collection was not mandated for all patients and the inability to specifically quantitate tumour-derived cfDNA fraction in cfDNA. CONCLUSIONS We report that changes in cfDNA concentrations correlate with both rPFS and OS in patients receiving first- and second-line taxane therapy, and may serve as independent prognostic biomarkers of response to taxanes. PATIENT SUMMARY In the past decade, several new therapies have been introduced for men diagnosed with metastatic prostate cancer. Although metastatic prostate cancer remains incurable, these novel agents have extended patient survival and improved their quality of life in comparison with the last decade. To further optimise treatment allocation and individualise patient care, better tests (biomarkers) are needed to guide the delivery of improved and more precise care. In this report, we assessed cfDNA in over 2500 blood samples from men with prostate cancer who were recruited to two separate international studies and received taxane chemotherapy. We quantified the concentration of cfDNA fragments in blood plasma, which partly originates from tumour. We identified that higher concentrations of circulating cfDNA fragments, prior to starting taxane chemotherapy, can be used to identify patients with aggressive prostate cancer. A decline in cfDNA concentration during the first 3-9 wk after initiation of taxane therapy was seen in patients deriving benefit from taxane chemotherapy. These results identified circulating cfDNA as a new biomarker of aggressive disease in metastatic prostate cancer and imply that the study of cfDNA has clinical utility, supporting further efforts to develop blood-based tests on this circulating tumour-derived DNA.

Abstract
PURPOSE Single-agent oral chemotherapy is widely used in patients with bone metastases without visceral involvement, especially in hormone receptor-positive metastatic breast cancer (mBC). However, this option has been poorly evaluated in clinical trials. METHODS Eligible patients had mBC with predominantly bone but not visceral metastases, were receiving bisphosphonate therapy, and had previously received endocrine therapy (any setting) but not chemotherapy for mBC. Patients received oral vinorelbine 60 mg/m2 on days 1, 8, 15, and 22 every 4 weeks (escalating to 80 mg/m2 from cycle 2 in the absence of grade 3/4 toxicity) until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). Secondary endpoints included clinical benefit rate (complete/partial response or ≥24 weeks' stable disease), overall survival, and safety. RESULTS Seventy patients were treated for a median of 6 cycles (range 1-18). Most (73%) continued treatment until disease progression. After 43 months' median follow-up, median PFS was 8.2 months (95% confidence interval [CI], 5.5-9.8). The clinical benefit rate was 56% (95% CI, 43%-68%). Median overall survival was 35.2 months (95% CI, 26.8-47.1). The most common grade 3/4 adverse event was neutropenia (38% of patients); febrile neutropenia was absent. The most common grade 1/2 adverse events were bone pain, fatigue, and gastrointestinal toxicities. Alopecia was infrequent. CONCLUSIONS In patients with hormone receptor-positive mBC, bone disease, and prior endocrine therapy, first-line oral vinorelbine chemotherapy demonstrated long PFS and good tolerability. In this setting, it could be considered as an active oral alternative to intravenous chemotherapy.

Abstract
Breast cancer ranks first among the malignant tumors in women. In locally advanced breast cancer (LABC) treatment starts with neoadjuvant chemotherapy (CTx) with the standard regimens CMF, FAC, АС. A cytostatic drug, Arglabin, isolated and produced from Artemisia glabella Kar. et Kir., an endemic plant growing in Central Kazakhstan, has been under investigation in clinical trials. The research is aimed at investigating the long-term results of combination therapy of locally advanced breast cancer including different chemotherapy regimens and Arglabin as monotherapy. The present research includes 93 patients diagnosed with LABC aged from 35 to 75 years, including 60 patients with Stage 2, and 33 patients with Stage 3 breast cancer. All patients were split into 3 groups, two experimental and one control group. The control group consisted of 36 patients with LABC who underwent 4 cycles of neoadjuvant chemotherapy according to AC regimen (doxorubicine 50 mg/m2, cyclophosphamide 500 mg/m2). The experimental group 1 consisted of 30 patients who received 4 cycles of chemotherapy according to AC+Arglabin regimen (Arglabin 370 mg/m2 within 7 days), while experimental group 2 consisted of 27 patients who underwent 4 cycles of Arglabin as monotherapy. Actuarial calculations of the overall survival (OS) and disease-free survival (DFS) rates were done according to the Kaplan-Meier method, while the differences in indicators of control and experimental groups were estimated using the following methods: Cox's F-Test, χ2, Gehan's Wilcoxon Test. Overall one- and two-year survival in all groups of patients was 100%. Three-year survival rate in patients treated with chemotherapy according to AC regimen was (40,0±8,2)%, in patients combining AC chemotherapy with Arglabin it was (60,0±8,9)%. The lowest three-year survival rate (28,0±8,6)% was observed in patients treated with Arglabin as a monotherapy. The three-year survival rate in patients with breast cancer is statistically insignificant (χ2=4,407 at p=0,11042) between all groups; however, at the paired comparison by Gehan's Wilcoxon criterion a statistically significant difference has been observed between the group treated with Arglabin as monotherapy, and the group receiving chemotherapy according to AC+Arglabin regimen. The highest disease-free survival rates have been observed in the group of patients receiving chemotherapy according to AC+Arglabin regimen: 1-2-3-year survival rates are 100%, 100%, and 58%, respectively. In the group of patients who underwent chemotherapy according to AC regimen, 1-2-3-year disease-free survival rates are 92%, 92%, and 30%, respectively. Arglabin included in AC regimen positively increases a 3-year disease-free survival rate by 28% as compared to the standard regimen.

Abstract
BACKGROUND Mild-to-moderate AIDS-associated Kaposi sarcoma (KS) often responds to antiretroviral therapy (ART) alone; the role of chemotherapy is unclear. We assessed the impact of immediate vs as-needed oral etoposide (ET) among human immunodeficiency virus (HIV)-infected individuals with mild-to-moderate KS initiating ART. METHODS Chemotherapy-naive, HIV type 1-infected adults with mild-to-moderate KS initiating ART in Africa and South America were randomized to ART (tenofovir/emtricitabine/efavirenz) alone (chemotherapy "as-needed" arm) vs ART plus up to 8 cycles of oral ET (immediate arm). Participants with KS progression on ART alone received ET as part of the as-needed strategy. Primary outcome was ordinal as follows: failure, stable, and response at 48 weeks. Secondary outcomes included time to initial KS progression, KS-associated immune reconstitution inflammatory syndrome (KS-IRIS), and KS response. RESULTS Of 190 randomized participants (as-needed = 94, immediate = 96), the majority were men (71%) and African (93%). Failure (53.8% vs 56.6%), stable (16.3% vs 10.8%), and response (30% vs 32.5%) did not differ between arms (as-needed vs immediate) among those with week 48 data potential (N = 163, P = .91). Time to KS progression (P = .021), KS-IRIS (P = .003), and KS response (P = .003) favored the immediate arm. Twenty-five participants died (13%). Mortality, adverse events, CD4+ T-cell changes, and HIV RNA suppression were similar at 48 weeks. CONCLUSIONS Among HIV-infected adults with mild-to-moderate KS, immediate ET provided early, nondurable clinical benefits. By 48 weeks, no clinical benefit was observed compared to use of ET as needed. Mortality was high and tumor response was low. CLINICAL TRIALS REGISTRATION NCT01352117.

Abstract
BACKGROUND Intraperitoneal administration of paclitaxel had been considered a promising option to treat peritoneal metastasis, the most frequent pattern of recurrence in gastric cancer after D2 gastrectomy, but its safety and efficacy after gastrectomy had not been fully explored. METHODS A phase II randomized comparison of postoperative intraperitoneal (IP) vs. intravenous (IV) paclitaxel was conducted. Patients with resectable gastric linitis plastica, cancer with minimal amount of peritoneal deposits (P1), or cancer positive for the peritoneal washing cytology (CY1) were eligible. After intraoperative confirmation of the above disease status and of resectability, patients were randomized to be treated either by the IP therapy (paclitaxel 60 mg/m2 delivered intraperitoneally on days 0, 14, 21, 28, 42, 49, and 56) or the IV therapy (80 mg/m2 administered intravenously using the identical schedule) before receiving further treatments with evidence-based systemic chemotherapy. The primary endpoint was 2-year survival rate. RESULTS Of the 86 patients who were randomized intraoperatively, 83 who actually started the protocol treatment were eligible for analysis (n = 39, IP group; n = 44, IV group). The 2-year survival rate of the IP and IV groups was 64.1% (95% CI 47.9-76.9) and 72.3% (95% CI 56.3-83.2%), respectively (p = 0.5731). The IP treatment did not confer significant overall or progression-free survival benefits, and was associated with particularly poor performance in patients with residual disease, including the CY1 P0 population. CONCLUSIONS We were unable to prove superiority of the IP paclitaxel over IV paclitaxel delivered after surgery to control advanced gastric cancer with high risk of peritoneal recurrence.
