Aim: We performed an updated meta-analysis to evaluate the efficacy and safety of lenvatinib in cancer patients. Materials & methods: Databases were searched to identify relevant trials. Data were extracted to evaluate overall survival, progression-free survival, overall response rate and grade ≥3 adverse events. Results: The pooled analysis demonstrated that lenvatinib significantly improved progression-free survival (hazard ratio: 0.43; 95% CI: 0.23–0.80; p = 0.008), overall survival (hazard ratio: 0.85; 95% CI: 0.75–0.97; p = 0.013) and overall response rate (relative risk: 6.89; 95% CI: 2.22–21.36; p = 0.001) compared with control therapy. However, the use of lenvatinib can increase the risk of severe infection. Conclusion: Lenvatinib-containing regimens are associated with better progression-free survival, overall survival and overall response rate, but can induce severe infection.

Background Patients with locally advanced, recurrent or metastatic solitary fibrous tumour are often treated with bevacizumab and temozolomide based on the clinical efficacy reported in a case series of 14 patients. Given the rarity of solitary fibrous tumour, large trials are not feasible. We report the efficacy of this regimen based on a population-based analysis. Methods This was a population-based retrospective, multi-centre analysis using patient data from a provincial cancer registry and treatment database. Cases from June 2006 through October 2016 were identified for patients receiving bevacizumab and temozolomide for locally advanced, recurrent or metastatic solitary fibrous tumour or hemangiopericytoma, which is sometimes used to describe tumours arising from the meninges. The primary outcome was overall response rate. Secondary outcomes included time to response, progression free survival and overall survival estimated using the Kaplan–Meier method. Results Fourteen patients were identified: median age 59 (range 44–70), male 78.6%. Diagnoses were solitary fibrous tumour in 10 (71.4%) and hemangiopericytoma in four (28.6%), with metastatic disease in 10 (72.7%) patients. The most common primary sites were meninges in four (28.6%) and pelvis in three (21.4%) patients. The median follow-up was 15.5 months, with median treatment of four months. Overall response rate was 21.4% (no complete response, 3 partial response), with median time to response of four months. Median progression free survival, six-month progression free survival and overall survival were 17 months, 65.0%, and 45 months, respectively. Conclusions Efficacy of bevacizumab and temozolomide in solitary fibrous tumour appeared to be similar to that previously reported. Our findings confirmed that bevacizumab and temozolomide is an effective and tolerated treatment for this patient population.

Purpose We report the efficacy and safety of dabrafenib (BRAF inhibitor) and trametinib (MEK inhibitor) combination therapy in BRAF V600E–mutated anaplastic thyroid cancer, a rare, aggressive, and highly lethal malignancy with poor patient outcomes and no systemic therapies with clinical benefit. Methods In this phase II, open-label trial, patients with predefined BRAF V600E–mutated malignancies received dabrafenib 150 mg twice daily and trametinib 2 mg once daily until unacceptable toxicity, disease progression, or death. The primary end point was investigator-assessed overall response rate. Secondary end points included duration of response, progression-free survival, overall survival, and safety. Results Sixteen patients with BRAF V600E–mutated anaplastic thyroid cancer were evaluable (median follow-up, 47 weeks; range, 4 to 120 weeks). All patients had received prior radiation treatment and/or surgery, and six had received prior systemic therapy. The confirmed overall response rate was 69% (11 of 16; 95% CI, 41% to 89%), with seven ongoing responses. Median duration of response, progression-free survival, and overall survival were not reached as a result of a lack of events, with 12-month estimates of 90%, 79%, and 80%, respectively. The safety population was composed of 100 patients who were enrolled with seven rare tumor histologies. Common adverse events were fatigue (38%), pyrexia (37%), and nausea (35%). No new safety signals were detected. Conclusion Dabrafenib plus trametinib is the first regimen demonstrated to have robust clinical activity in BRAF V600E–mutated anaplastic thyroid cancer and was well tolerated. These findings represent a meaningful therapeutic advance for this orphan disease.

Summary Purpose Apatinib, a new tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor-2, has shown promising efficacy against several solid cancers, but evidence of its efficacy against relapsed and refractory nasopharyngeal carcinoma is limited. We investigated the efficacy and safety of apatinib for relapsed and refractory nasopharyngeal carcinoma in an open-label, single-arm, phase II clinical trial. Fifty-one patients with relapsed and refractory nasopharyngeal carcinoma in the First Affiliated Hospital, Zhengzhou University, who met the inclusion criteria were enrolled in the study. All patients received apatinib at an initial dose of 500 mg daily (1 cycle = 28 days). The primary and secondary endpoints were overall response rate, progression-free survival, and overall survival. We evaluated treatment effects and recorded apatinib-related adverse events by performing regular follow-ups and workup. The overall response rate (complete and partial responses) was 31.37% (16/51). The median overall survival and progression-free survival were 16 (95% CI, 9.32–22.68) and 9 months (95% CI, 5.24–12.76), respectively. Most patients tolerated treatment-related adverse events of grades 1 and 2; hypertension (29, 56.86%), proteinuria (25, 49.02%), and hand–foot syndrome (27, 52.94%) were the most common adverse events. There were no treatment-related deaths. Apatinib showed good efficacy and safety in patients with relapsed and refractory NPC.

Abstract Abstract 1634FN2 Introduction: The treatment of patients with DLBCL who are unsuitable for anthracycline containing chemotherapy remains a clinical challenge. Gemcitabine is a nucleoside analogue which has proven efficacy in the relapse setting in both non Hodgkin's and Hodgkin's lymphoma. We therefore developed a protocol incorporating Gemcitabine in a first line approach combined with CVP-R chemo-immunotherapy in DLBCL patients considered unfit for anthracycline containing chemotherapy. Methods: We performed a prospective, multicentre phase II trial in patients with DLCBL who were considered unfit for anthracycline containing chemo-immunotherapy. Eligibility criteria included ejection fraction < 50%, or ejection fraction ≥ 50% but with the presence of attendant significant co-morbidities (including: ischaemic heart disease, hypertension, diabetes mellitus), and ECOG PS 0–3. Patients received 6 cycles of Rituximab (375 mg/m2 IV D1), Cyclophosphamide (750mg/m2 IV D1), Vincristine (1.4 mg /m2 IV D1), Prednisolone (100mg, orally D1–5) and Gemcitabine IV D1 and D8. The Gemcitabine dose, if tolerated was sequentially escalated from 750mg/m2 in cycle 1 to 875mg/m2 in cycle 2 to 1000mg/m2 in cycle 3 with the dose maintained at 1000mg/m2 for cycles 4–6. Cycles were repeated every 21 days with growth factor support administered on day 9 of each cycle (pegfilgrastrim 6mg s/c).The primary endpoint was to achieve an overall response rate of > 40% assessed by CT scan at the end of treatment according to the Cheson criteria. Secondary endpoints were progression free survival and overall survival. Results: 62 patients were recruited from 32 UK sites over a 28 month period from April 2008 to July 2010. 66% were male. Median age was 76 years (range 52–90), 48 (77%) were > 70 years. 43 (69%) had stage III/IV disease and 46 (72%) had high – intermediate or high IPI (3–5) disease. ECOG performance status was ≥ 2 in 50% patients. Left ventricular ejection fraction (LVEF) was < 50% in 28 patients (45%). The 34 patients with LVEF ≥ 50% had significant co-morbidities, 22 (65%) had multiple co-morbidities. 44 (70%) received ≥ 3 cycles of treatment, reasons for early termination of treatment in the remaining 18 patients were progression (n=2), toxicity (n=5), death (n=6) patient choice (n=1) and other (n=4). 29 patients (47%) received the full 6 cycles. A total of 250 treatment cycles were delivered. Of the 44 patients who received ≥ 3 cycles of treatment, the dose of Gemcitabine was escalated to the full dose (1000mg/m2) in 67%. Day 8 Gemcitabine was delivered in 215/250 (86%) cycles of treatment. The overall response rate (CR/CRu/PR) at end of treatment for all 62 patients was 60%. For patients who received ≥ 3 cycles of treatment (n =44) the ORR was 79.5% at the end of treatment. There was no significant difference in ORR between those with LVEF <50% and those with LVEF ≥ 50% (71% vs 53%, p=0.155). At a median follow up of 18.2 months the 1 year progression free survival rate for all patients was 52.9% (95% CI 39.4–64.8). The 1 year overall survival (OS) rate is 62.4% (95% CI 48.5–73.6). For the group with LVEF <50% OS was 70.8% (95% CI: 48.4, 84.9) and LVEF group ≥ 50% OS was 55.9% (95% CI 37.1–71).Grade 3/4 haematological toxicity was observed in 54.1% patients. Grade 3/4 infection was observed in 24.6% of patients. The death rate observed related to infection for the whole cohort was 11%. Conclusion: This multicentre trial demonstrates that the R-GCVP regimen delivers excellent overall response rates with durable remissions in a group of patients where anthracycline use was precluded. The efficacy attained in this difficult group of patients provides a platform for testing the regimen in subsequent randomised phase II and phase III studies to confirm its efficacy. Disclosures: No relevant conflicts of interest to declare.

StreszczenieWraz ze stale rosnącą liczbą badań w dziedzinie hematologii, znajomość metod statystycznych wykorzystywanych w analizie i interpretacji wyników stała się niezbędnym narzędziem pracy klinicystów. W artykule omówiono najczęściej stosowane testy statystyczne oraz zdefiniowano punkty końcowe stosowane podczas raportowania rezultatów badań klinicznych. Testy statystyczne funkcjonują na zasadzie testowania hipotez. Odrzucenie lub nieodrzucenie danej hipotezy zależy od wybranego poziomu istotności oraz wyliczonej wartości p. Z kolei otrzymany przedział ufności wskazuje na wielkość efektu i precyzję oszacowania. W hematologii głównie raportowanymi punktami końcowymi są: całkowite przeżycie (ang. overall survival – OS), przeżycie wolne od progresji (ang. progression-free survival – PFS), odpowiedź na leczenie (ang. overall response rate – ORR) oraz coraz częściej spotykana, ocena terapii raportowana przez pacjenta (patient reported outcome – PRO). Biorąc pod uwagę kierunek rozwoju medycyny, znajomość biostatystyki jest niezbędna w podejmowaniu decyzji terapeutycznych, a także ocenianiu, interpretowaniu i raportowaniu wyników przeprowadzonych badań.

Background: Prostate cancer is the sixth leading cause of death, among all cancer deaths By 2030, this burden is expected to increase with 1.7 million new cases and 499,000 new deaths. We aimed to evaluate the efficacy and safety of Nilutamide in metastatic prostate cancer (mPCa) patients who underwent orchiectomy. Methods: A comprehensive search was conducted in the Medline/PubMed and Cochrane Library. References from included studies and studies from clinicaltrials.gov were explored without language and date restrictions. We included only randomized controlled trials, comparing the safety and efficacy of Nilutamide in Metastatic Prostate Cancer (mPCa) patients who underwent orchiectomy with placebo. The outcomes of concerns were survival and the response of drug and safety.. Quality of the included studies was assessed using the Cochrane Risk of Bias Tool. Two authors were independently involved in the study selection, data extraction and quality assessment. Disagreements between the two reviewers were resolved by consulting a third reviewer. Results: A total of five out of 244 studies were included in meta-analysis involving1637 participants. Nilutamide group showed improved response rate (RR=1.77, 95%CI 1.46-2.14, p<0.00001), disease progression (RR=0.59, 95%CI 0.47-0.73, p<0.00001), complete response (RR=2.13, 95%CI 1.40-3.23, p=0.003) and clinical benefit (RR=1.23, 95%CI 1.13-1.34, p<0.00001) when compared to placebo; however, stable disease favored the control group (RR=0.80, 95%CI 0.68-0.94, p=0.007). In addition, patients on Nilutamide showed prolonged progression-free survival and overall survival. Nausea and vomiting were the most common adverse events reported in Nilutamide group. Conclusion: Evidence suggests that patients with mPCa who underwent orchiectomy receiving Nilutamide showed significant improvement in progression-free survival and overall survival response rate and clinical benefits in comparison with the placebo group.

Tumor Mutational Burden

BackgroundHigh tumor mutational burden (TMB) and PD-L1 expression are associated with improved clinical outcomes in patients (pts) with non-small cell lung cancer (NSCLC) treated with immune checkpoint inhibitors (ICIs). However, how TMB performs as a predictive biomarker to ICIs in different PD-L1 expression subgroups is not well characterized.MethodsWe collected clinicopathologic and genomic data from NSCLCs which underwent targeted NGS and TMB assessment at DFCI. An unbiased recursive partitioning (URP) algorithm was used to investigate an optimal TMB cut-off with respect to objective response rate (ORR) in the subset of pts treated with ICIs. This TMB cut-off was then validated in the prospective POPLAR/OAK cohort.ResultsAmong 3560 NSCLCs identified, median TMB was significantly higher among current smokers compared to former (P<0.0001) and never smokers (P<0.0001), and there was a significant correlation between TMB and pack-years (figure 1A-B). Pts with BRAF or KRAS mutations had the highest median TMB (10.9 and 9.8 mutations/Megabase [mut/Mb], respectively), while tumors with RET and ALK alterations had the lowest median TMB of 5.3 mut/Mb (figure 2A-B). Tumors with PD-L1 expression of ≥50% had significantly higher median TMB compared to those with a PD-L1 expression of 1–49% (P=0.002) and <1% (P<00001). Among pts treated with ICIs (N=690), URP identified an optimal grouping TMB cut-off for ORR of 19.0 mut/Mb, which corresponded to the 90th percentile. Pts with a TMB of ≥19.0 mut/Mb had a significantly higher ORR (45.2% vs 20.1%, P<0.0001) and longer median PFS (11.0 vs. 2.9 months, HR:0.49, P<0.0001) and OS (20.8 vs. 11.2 months, HR:0.59, P=0.001) compared to those with a TMB of <19.0 mut/Mb (figure 3A-C). A TMB of ≥19.0 mut/Mb was an independent predictor of improved PFS and OS at multivariable analysis (table 1). A TMB within the top 10th percentile was confirmed to correlate with improved ORR and PFS in atezolizumab arm but not in the docetaxel arm of the POPLAR/OAK trials (figure 4A-B). When TMB and PD-L1 where integrated in the URP, we identified an optimal cut-off of 19 mut/Mb among cases with a PD-L1 expression of ≤25%, and of 8.4 mut/Mb among those with a PD-L1 expression of >25%, suggesting that TMB differentially impacts response to immunotherapy among PD-L1 high versus low NSCLCs (figure 5).Abstract 246 Figure 1(A) Correlation between TMB and smoking status.

AbstractThis analysis assessed the efficacy and safety of lenalidomide + dexamethasone in patients with relapsed or refractory multiple myeloma (MM) previously treated with thalidomide. Of 704 patients, 39% were thalidomide exposed. Thalidomide-exposed patients had more prior lines of therapy and longer duration of myeloma than thalidomide-naive patients. Lenalidomide + dexamethasone led to higher overall response rate (ORR), longer time to progression (TTP), and progression-free survival (PFS) versus placebo + dexamethasone despite prior thalidomide exposure. Among lenalidomide + dexamethasone-treated patients, ORR was higher in thalidomide-naive versus thalidomide-exposed patients (P = .04), with longer median TTP (P = .04) and PFS (P = .02). Likewise for dexamethasone alone-treated patients (P = .03 for ORR, P = .03 for TTP, P = .06 for PFS). Prior thalidomide did not affect survival in lenalidomide + dexamethasone-treated patients (36.1 vs 33.3 months, P > .05). Thalidomide-naive and thalidomide-exposed patients had similar toxicities. Lenalidomide + dexamethasone resulted in higher rates of venous thromboembolism, myelosuppression, and infections versus placebo + dexamethasone, independent of prior thalidomide exposure. Lenalido-mide + dexamethasone was superior to placebo + dexamethasone, independent of prior thalidomide exposure. Although prior thalidomide may have contributed to inferior TTP and PFS compared with thalidomide-naive patients, these parameters remained superior compared with placebo + dexamethasone; similar benefits compared with placebo + dexamethasone were not evident for thalidomide-exposed patients in terms of overall survival. Studies were registered at http://www.clinicaltrials.gov under NCT00056160 and NCT00424047.

Introduction Almost half of patients with non-small-cell lung cancer (NSCLC) are diagnosed at an advanced stage. Our aim was to assess the effects of adding necitumumab to chemotherapy in patients with stage IV NSCLC. Material and methods A comprehensive literature search was performed according to pre-specified inclusion and exclusion criteria. Data on overall survival, progression-free survival, objective response rate and adverse events were extracted. A meta-analysis was performed to obtain pooled hazard ratios (HR) and corresponding 95% confidence intervals (CI) for time-to-event data and pooled odds ratio (OR) with 95% CI for dichotomous outcomes. Results The meta-analysis included four randomized clinical trials with 2074 patients. The pooled results showed significant improvement for overall survival (HR = 0.87 (95% CI 0.79–0.95), p = 0.004) when necitumumab was added to chemotherapy in patients with advanced NSCLC. No statistically significant improvement was noted for progression-free survival and objective response rate (HR = 0.83 (95% CI 0.69–1.01), p = 0.06 and OR = 1.46 (95% CI 0.90–2.38), p = 0.13, respectively). Subgroup analysis showed that in patients with non-squamous NSCLC, there was no benefit in overall survival and objective response rate. Patients with advanced NSCLC who received necitumumab were at the highest odds of developing a skin rash (OR = 14.50 (95% CI 3.16–66.43), p = 0.0006) and hypomagnesaemia (OR = 2.77 (95% CI 2.23–3.45), p < 0.00001), while the OR for any grade ≥3 adverse event was 1.55 (95% CI 1.28–1.87, p < 0.00001). Conclusions The addition of necitumumab to standard chemotherapy in a first-line setting in patients with stage IV NSCLC results in a statistically significant improvement in overall survival, while the results were not significant for progression-free survival and objective response rate.
