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.

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.

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.

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.

PURPOSE Recurrent or metastatic adenoid cystic carcinoma (R/M ACC) is a malignant neoplasm of predominantly salivary gland origin for which effective therapies are lacking. We conducted a phase II trial evaluating the multitargeted tyrosine kinase inhibitor lenvatinib in patients with R/M ACC. PATIENTS AND METHODS This study was conducted with a two-stage minimax design. Patients with histologically confirmed R/M ACC of any primary site with radiographic and/or symptomatic progression were eligible. Any prior therapy was allowed except previous lenvatinib. Patients received lenvatinib 24 mg orally per day. The primary end point was overall response rate. Secondary end points were progression-free survival and safety. An exploratory analysis of how MYB expression and genomic alterations relate to outcomes was conducted. RESULTS Thirty-three patients were enrolled; 32 were evaluable for the primary end point. Five patients (15.6%) had a confirmed partial response, 24 patients (75%) had stable disease, two patients (6.3%) discontinued treatment as a result of toxicity before the first scan, and one patient (3.1%) had progression of disease as best response. Median progression-free survival time was 17.5 months (95% CI, 7.2 months to not reached), although only eight progression events were observed. Patients otherwise were removed for toxicity (n = 5), as a result of withdrawal of consent (n = 9), or at the treating physician’s discretion (n = 6). Twenty-three patients required at least one dose modification, and 18 of 32 patients discontinued lenvatinib for drug-related issues. The most common grade 3 or 4 adverse events were hypertension (n = 9; 28.1%) and oral pain (n = 3; 9.4%). Three grade 4 adverse events were observed (myocardial infarction, n = 1; posterior reversible encephalopathy syndrome, n = 1; and intracranial hemorrhage, n = 1). CONCLUSION This trial met the prespecified overall response rate primary end point, demonstrating antitumor activity with lenvatinib in R/M ACC patients. Toxicity was comparable to previous studies, requiring monitoring and management.

PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

Abstract Purpose: Rituximab combined with chemotherapy has been recommended as first-line or second-line standard regimen in most subtypes of B-cell lymphoma in China by the 2004 National Comprehensive Cancer Network lymphoma therapy guideline. We have conducted a multicenter trial to evaluate the efficacy and safety of rituximab in combination with standard chemotherapy (CHOP) in patients with previously untreated or relapsed indolent and aggressive NHL. Methods: Patients received 4–8 cycles of rituximab plus CHOP every 21 days. For each cycle, rituximab (375mg/m2) was given on day 1 and CHOP started on day 3. CHOP consisted of cyclophosphamide 750mg/m2, doxorubicin 50mg/m2, and vincristine 1.4mg/m2 (maximum 2mg/dose) given intravenously on day 3, and oral prednisone 100mg on days 3–7. Results: A total of 221 patients were enrolled on the trial, 128 males and 93 females with a mean age of 49 years (range 10–83 years). The main lymphoma subtypes were small lymphocytic (15 patients, 7%), follicular (27 patients, 12%), and diffuse large B-cell (160 patients, 72%). In total, 56 patients had indolent NHL and 165 aggressive NHL. The overall response rate for all patients was 86% with 57% complete responses. In patients with indolent NHL the overall and complete response rates were 95% and 55% respectively. After a median 12 months follow up, progression-free survival in patients with indolent NHL was 88%±5% at 1 year and 83%±6% at 2 years. In the 160 patients with diffuse large B-cell lymphoma, the overall response rate was 88% with 61% complete responses, and after a mean follow-up of 6 months, predicted 1-year and 2-year progression-free survival were 88%±5% and 83%±7% respectively. Infusion-related adverse events occurred in 4% of patients, associated with the first infusion of rituximab. Subanalyses according to subtype, stage, IPI and other factors will be presented. Conclusion: Rituximab plus chemotherapy is an effective, well-tolerated treatment that achieves high response rates and long progression-free survival in both indolent and aggressive NHL.

There is a lack of useful biomarkers for predicting the efficacy of anti–programmed death-1 (PD-1) therapy for advanced gastric and colorectal cancer. To address this issue, in this study we investigated the correlation between inflammatory marker expression and survival in patients with advanced gastric and colorectal cancer. Data for 111 patients with advanced gastric and colorectal cancer treated with anti–PD-1 regimens were retrospectively analyzed. Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and clinical characteristics of each patient were selected as the main variables. Overall response rate, disease control rate, and progression-free survival were primary endpoints, and overall survival and immune-related adverse events (irAEs) were secondary endpoints. The chi-squared test and Fisher’s exact test were used to evaluate relationships between categorical variables. Uni- and multivariate Cox regression analyses were performed, and median progression-free survival and overall survival were estimated with the Kaplan–Meier method. The overall response rate and disease control rate of anti–PD-1therapy in advanced gastric and colorectal tumors were 12.61 and 66.66%, respectively. The patients with MLR &lt; 0.31, NLR &lt; 5, and PLR &lt; 135 had a significantly higher disease control rate than those with MLR &gt; 0.31, NLR &gt; 5, and PLR &gt; 135 (P &lt; 0.05). The multivariate analysis revealed that MLR &lt; 0.31, BMI &gt; 18.5, and anti–PD-1 therapy in first-line were associated with prolonged PFS. MLR &lt; 0.31 and BMI &gt; 18.5 were associated with prolonged overall survival. The irAE rate differed significantly between PLR groups, and PLR &lt; 135 was associated with an increased rate of irAEs (P = 0.028). These results indicate that the inflammatory markers NLR, MLR, and PLR have clinical utility for predicting survival or risk of irAEs in patients with advanced gastric cancer and colorectal cancer.
