Abstract Background: Radionuclides such as Strontium-89, Samarium-153, and Radium-223 are commonly used for the treatment of bone metastases (BM) and they have shown efficacy in previous studies. The aim of this meta-analysis is to compare the curative performance of different types of radionuclides in patients with BM, and to provide evidence for further future research and clinical practice.Methods: The electronic databases of PubMed, Web of Science, Embase, Cochrane Library, Wanfang Data, and China National Knowledge Infrastructure (CNKI) were searched. Studies using radionuclides therapy to cure patients were included. Pooled overall response rate, occurrence rates of common adverse events, hazard ratio (HR), and their respective 95% confidence interval (CIs) were calculated.Results: A total of 28 articles with 33 studies patients were identified for inclusion in this meta-analysis. The types of radionuclides used in the studies contained 89Sr, 153Sm, 223Ra, 186Re, and 188Re. The overall response rate was 72% [66%, 77%]. The respective overall response rates of 89Sr, 153Sm, and 223Ra were 72% [64%, 79%], 80% [75%, 84%], and 54% [32%, 75%]. In the survival analysis, the pooled HR was 0.85 [0.67, 1.08]. The pooled occurrence rate of leucocyte hematological toxicity of any grade was 5% [2%, 8%]. The pooled occurrence rate of thrombocytopenia of any grade was 7% [5%, 8%]. With regard to anemia, the pooled occurrence rate of any grade was 15% [11%, 19%].Conclusion: The results of this meta-analysis indicate that radionuclides therapy is efficacious in patients, type of radionuclides and history of patients should be considered to prevent potential adverse events.

Aim: This meta-analysis aimed to evaluate the pharmacokinetics, efficacy, safety and immunogenicity of rHuPH20-facilitated subcutaneous (SC) administration of monoclonal antibody compared with intravenous (IV) administration for patients with cancer. Materials & methods: Outcomes included trough concentrations (Ctrough), overall response rate, adverse events, serious adverse events and antidrug antibody positivity rate. Subgroup analysis was also performed. Results: Five studies involving 1575 participants (788/787) were included. All studies met the non-inferiority criterion in Ctrough. No significant differences were observed in overall response rate (p = 0.12), adverse events (p = 0.05), and severe adverse events (p = 0.73) between SC and IV groups. The SC group also had lower immunogenicity than the IV group. Conclusion: rHuPH20-facilitated subcutaneous administration of monoclonal antibody is highly similar to IV administration in terms of pharmacokinetics, efficacy, and safety, but with lower immunogenicity.

Background: Immune-related adverse events (irAEs) are common during immune checkpoint inhibitor (ICI) treatment and reported to be associated with good survival. This study evaluated the association between onset timing of irAEs and survival of cancer patients treated with ICIs. Methods: Databases including PubMed, Embase, and the Cochrane library were systematically searched to retrieve clinical studies assessing the relationship between irAEs and survival in cancer patients with ICIs. The overall response rate for treatment response and hazard ratio (HR) for overall survival (OS) and progression-free survival (PFS) were calculated using RevMan 5.3. Subgroup analysis in terms of cancer type, ICIs type, region, specific irAEs, accordingly. Results: A total of 34 studies were included. The HRs for OS and PFS in cancer patients with versus without irAEs were 0.57 [95% confidence interval (CI): 0.44, 0.74; p < 0.0001], and 0.50 (95% CI: 0.37, 0.67; p < 0.00001), respectively. The odds ratio for overall response in cancer patients with irAEs was 4.72 (95% CI: 3.48, 6.40; p < 0.00001) compared with those without irAEs. Subgroup analyses suggested that the prognostic role of irAEs was associated with cancer types and region, but not irAEs types. The landmark analysis of OS revealed that there is a non-proportional (early) effect of irAEs on OS in ICI-treated cancer patients (landmark >12 weeks, HROS = 1.08; 95% CI: 0.89, 1.30; p = 0.46). Conclusion: Our findings suggest that the occurrence of irAEs could be a prognostic factor for cancer patients who were treated with ICIs.

e13017 Background: Activation of the mammalian target of rapamycin intracellular signaling pathway is one of the mechanisms of endocrine resistance in breast cancer. The addition of everolimus to exemestane improves progression-free survival (PFS) in patients with hormone receptor positive (HR+) advanced breast cancer (ABC) previously treated with nonsteroidal aromatase inhibitors (NSAIs). The aim of this study was to assess the effectiveness and safety of everolimus plus exemestane in patients with HR+ ABC. Methods: We retrospectively evaluated patients with HR+, HER2 negative ABC treated with everolimus/exemestane that recurred or progressed during/after treatment with NSAIs in a portuguese comprehensive cancer center. Study endpoints were PFS, overall survival (OS), overall response rate and adverse events. Results: Between April 2014 and September 2020, 63 female patients were treated with everolimus/exemestane. Median age was 59 years (36-79), and all had performance status ECOG ≤2. Seventeen (27.0%) patients had bone metastasis alone, 39 (61.9%) had bone and visceral metastasis, 25 (39.7%) had metastasis in 3 or more sites and 87.3% had previous hormone-sensitive disease. Before everolimus/exemestane, 61 (96.8%) patients were being treated with palliative endocrine therapy (alone or in combination with CDK4/6 inhibitors) or chemotherapy (ChT) and 2 (3.2%) patients were under adjuvant endocrine therapy. Median follow-up time was 12.8 months (1.4-74.6), with 39 patients alive. Overall response rate was 14.3% (1 complete response and 8 partial responses) and 45 patients had stable disease. Median PFS was 5.6 months (CI95% 2.4-8.8) and median OS was 25.4 months (CI95% 10.3-40.5). Subgroup analysis regarding PFS was statistically significant for previous treatment with CDK4/6 inhibitors (p = 0.026) and for site of metastasis (p = 0.025). In the subgroup of patients that previously underwent palliative ChT, median PFS was 4.0 months (CI95% 0.2-9.6) and median OS was 18.6 months (CI95% 8.2-29.0). For patients that did not receive previous palliative ChT, median PFS was 5.8 months (CI95% 3.8-7.8) and median OS was 43.5 months (CI95% 2.0-85.0). Grade 3 and 4 adverse events occurred in 21 (33.3%) patients, and were: nausea, anorexia, rash, headache, haematologic toxicity, hepatic cytolysis, hyperglycaemia, pneumonitis, oral mucositis and acute kidney failure with need for haemodialysis. Fifty-five (87.3%) patients suspended everolimus, 34 (54.0%) due to disease progression and 21 (33.3%) due to toxicity. Conclusions: Our results confirm the effectiveness and safety of everolimus/exemestane in real-world setting and support its use mainly before palliative ChT. Everolimus/exemestane in HR+ ABC is feasible in the clinic, with toxicity manageable under close surveillance.

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.

BackgroundCervical cancer is a common malignancy among women and, when recurring, presents a dismal prognosis. After platinum failure, second-line treatments report response rates ranging from 3–15%, a median progression-free survival of about 3 months and a median overall survival of about 5.5 months.To retrospectively evaluate the activity and safety of capecitabine in patients with advanced/recurrent cervical carcinoma.MethodsA retrospective review of medical records of recurrent cervical cancer patients, who had failed a previous platinum–paclitaxel treatment and received oral capecitabine 1250 mg/m2 twice daily continuously from day 1 to day 14 every 21 days, was performed from December 2013 to March 2018 at the Gynecologic Oncology Unit of the Fondazione IRCCS National Cancer Institute of Milan, Italy. The response rate was evaluated every three cycles according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1 criteria. Common Terminology Criteria for Adverse Events version 4.0 were used to evaluate adverse events.ResultsWe retrospectively analyzed 35 patients with recurrent cervical carcinoma, treated with oral capecitabine. All patients had previously received and failed a combination of carboplatin plus paclitaxel as first-line therapy for advanced/recurrent disease. Median age at the first capecitabine administration was 53 years (range 27–82). All patients were evaluable for response: the overall response rate was 34.2% (2.8% complete responses and 31.4% partial responses) with a clinical benefit rate of 57% (overall response rate plus 22.8% stabilizations of disease). The most common grade 1–2 adverse events per patient were fatigue (71.3%), hand-foot syndrome (57.0%), diarrhea (31.3%), constipation (17.0%), and nausea (10.4%). Only three patients (8.5%) reported grade 3 adverse events.ConclusionsOur data suggest that oral capecitabine should be considered an active and safe treatment in patients with recurrent cervical carcinoma after platinum failure. Based on these results, we consider capecitabine as warranting further clinical evaluation.

Abstract Background: Primary systemic amyloidosis (AL) is an incurable plasma cell disorder. Lenalidomide, especially in conjunction with dexamethasone, has been shown to be highly active in patients with multiple myeloma. Methods: We studied the toxicity and efficacy of lenalidomide in patients with symptomatic AL. Patients received single agent lenalidomide. If progression by 3 months or no evidence of hematologic response after 3 cycles, dexamethasone was added. Originally, twenty-three patients (Cohort 1) were enrolled according to study design. Because of a significant early drop out rate and notable activity of the regimen, the trial was modified to include an additional 15 patients (Cohort 2). Baseline characteristics and adverse events are available for all enrolled patients, but at the time of this writing, response data are available for Cohort 1 patients due to short follow-up of Cohort 2, but will be updated by the time of the meeting. Results: Median age was 64 years, with 69% male. Twenty-three were previously treated. Organ involvement was cardiac (67%), renal (64%), hepatic (17%), nerve (17%). Thirty-three, twenty-two, and forty-four percent of patients were cardiac biomarker stage 1, 2, and, 3 respectively. Of the 37 patients, one was a cancel, and 6 have not yet made it through 3 months of protocol treatment and event monitoring. The respective median follow-ups for Cohorts 1 and 2 are 17 and 3.4 months. Of the remaining, 30 patients, within the first 3 cycles of therapy fifteen patients discontinued treatment: 7 early deaths and 8 adverse events or other causes. Three additional patients died 0.5 to 2 months after stopping treatment. The best predictor for early withdrawal and/or death was baseline NT-proBNP and cardiac biomarker staging system (cut-offs for serum troponin T &lt;0.035 ng/ml and NT-proBNP &lt;332 pg/ml--Stage I neither above cut-off; Stage III, both above cut-off; and Stage II, one above cut-off). Figure1 Figure1. Figure 2 Figure 2. Of the twenty 22 patients assessed for response ten patients responded to treatment for an overall response rate of 45%, including 23% organ responders. Among the patients with organ responses, there were four renal responses, two cardiac responses and two liver responses. All but one of the responders had dexamethasone added to their treatment program. The most common grade 3−4 adverse events at least possibly attributable to lenalidomide were neutropenia (38%), thrombocytopenia (21%), fatigue (15%), and rash (12%). Conclusions: Lenalidomide and dexamethasone has significant activity in patients with AL with an overall response rate of 45%. Baseline NT−proBNP may be an effective eligibility screening strategy for subsequent trials.

Abstract Background: Multiple myeloma disproportionately affects the elderly and is currently an incurable malignancy. New therapies for myeloma, particularly oral therapies, are urgently needed. Objectives: To determine if thalidomide with or without other agents, improves response rate (≥ 50% reduction in monoclonal protein), survival, and/or progression in patients with previously untreated myeloma. To determine the frequency and significance of major adverse events associated with thalidomide in this setting. Methods: A literature search of Medline (1966–June 2006), Embase (1980–June 2006), the Cochrane Library, abstracts from the annual meetings of the American Society of Hematology (1999–2005) and the American Society of Oncology (1999–2006) was completed with a pre-specified search strategy. No language restrictions were applied. Randomized controlled trials of induction thalidomide (any dose, any duration) for adults with previously untreated multiple myeloma were included. Trials of exclusively maintenance therapy were excluded. Two reviewers independently extracted data. The methodological quality of selected trials was assessed and summarized. Weighted data was expressed as relative risk, risk difference, number needed to treat (NNT), and number needed to harm (NNH). A random-effects model was used. Results: Six eligible studies involving almost two thousand patients (N=1875) were identified and meta-analyzed. Two studies were published and four were reported in abstract form only. Five studies reported overall response rate (ORR); the four largest trials reported statistically significant improvements in ORR with the addition of thalidomide to standard therapy. The weighted relative risk of responding to a thalidomide-containing regimen versus control was 1.50 (95% CI 1.21 to 1.86). The NNT to achieve one additional response with thalidomide was 4 (95% CI 2.9 to 8.3). Two trials reported improvements in EFS/PFS. One trial reported an improvement in OS. The risk of VTE, peripheral neuropathy, and constipation was consistently elevated with thalidomide such that for every 50 patients treated with a thalidomide-containing-regimen, one could expect 12 to 13 additional patients to respond, 4 additional patients to develop VTE (NNH 12.5; 95% CI 8.3 to 20), 2 additional patients to develop peripheral neuropathy (NNH 25; 95% CI 16.7 to 50), and 4 additional patients to develop constipation (NNH14; 95% CI 10 to 25). In our analyses, prophylactic anticoagulation appeared to decrease, but not abolish, the risk of VTE with thalidomide. Conclusions: Thalidomide improves response rate and possibly progression free and overall survival in patients with previously untreated myeloma. It also increases the incidence of VTE, neuropathy, constipation and other adverse events. Further studies are required to confirm the survival advantage seen in one study, and to determine the optimum strategy for VTE prophylaxis.

Abstract This study's objective was to evaluate the efficacy and safety of gemcitabine in combination with oxaliplatin (GEMOX) as a salvage regimen in patients with relapsed or refractory Hodgkin's lymphoma. Twenty-five patients were enrolled. All patients had received ≥ 2 prior chemotherapy regimens, had an ECOG performance status ≤ 2 and had adequate organ function. Patients received intravenous gemcitabine (1000 mg/m2) and oxaliplatin (100 mg/m2) on days 1 and 15, every 4 weeks. The median age was 29 years (range, 18-64) and 16 (68%) were male. Twenty-one (84%) had primary refractory disease (n=13) or relapsed within 12 months after initial therapy (n=8). All had previous platinum-based salvage chemotherapy (ICE, 23; DHAP, 2). Ten patients (40%) had relapsed/refractory disease following autologous stem cell transplantation (SCT). None had previous brentuximab vedotin treatment. Twenty-one (84%) patients were refractory or progressive on the last treatment. Median number of previous lines of chemotherapy was 2 (range, 2-4). Median number of GEMOX cycles administered to the patients was 3 (range, 2-6). Treatment response was evaluated with PET-CT before and 2-3 cycles after treatment, and those patients who demonstrated a response continued to receive a maximum of 6 courses of GEMOX or bridged to SCT. Of 25 patients, 2 (8%) had complete response, 9 (36%) had partial response and the remaining patients had refractory/progressive disease with an overall response rate of 44%. Seven of the 10 patients who had relapsed/refractory disease after autologous SCT achieved a response (CR, 2; PR, 5). The median time to progression for responding patients was 3 months (range, 1-40 months). One patient is disease free for 40 months. Three patients were successfully bridged to SCT (autologous, 2; allogeneic, 1). Main toxicity was hematological. Grade ≥ 3 hematologic toxicity occurred in 10 patients: thrombocytopenia (36%), neutropenia (16%) and anemia (8%). Among these, 7 had previous autologous SCT. One patient had grade 4 neutropenia and thrombocytopenia. Treatment cycle postponed in 6 patients without dose reduction because of hematological toxicity. Seven patients (28%) needed G-CSF support. One patient developed febrile neutropenia. No treatment-related deaths occurred. GEMOX was shown to be an effective salvage regimen in patients with relapsed/refractory Hodgkin's lymphoma, producing an overall response rate of 44%. It is an active regimen in patients who had relapsed/refractory disease after autologous SCT. Although, the median PFS time was short, some patients can be bridged to SCT and some can get long-term PFS. Hematological toxicity was common, especially in patients with previous autologous SCT.

e18515 Background: A wide range of chemotherapeutic agents have demonstrated antitumor activity in patients with recurrent or metastatic Nasopharyngeal Cancers (NPC). These therapeutic agents have different efficacy and toxicity profile. Capecitabine monotherapy had activity in recurrent/metastatic NPC based on small previous retrospective studies. The primary objective is to evaluate the overall response rate and tolerability of capecitabine in recurrent/metastatic NPC. Methods: A retrospective electronic chart review performed for 51 cases of recurrent/metastatic NPC patients who received capecitabine 1000-1,250 mg/m² twice daily two weeks on, one week off between 2011 to 2019 at King Faisal Specialist Hospital & Research Center (KFSH&RC). The Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 was used. Results: The median age at diagnosis was 42 years. 98% had a non-keratinized undifferentiated squamous cell carcinoma (Grade III). The most common sites for metastases were Bone (58.3%), Lung (50.0%), and liver (45.8%). 95% of patients received platinum-based chemotherapy and radiation therapy as the primary treatment. Capecitabine was used as the second or third line of treatment in the metastatic setting 45.1% and 43.1%, respectively. The patients tolerated the standard dose for a median of 6 cycles; only 20.0% of patients required a 25% dose reduction. The best response for capecitabine was complete response in 8 patients (15.7%), partial response in 14 patients (27.5%), stable disease in 10 patients, (19.6%), with a clinical benefit achieved in 32 patients (62.7%), and progressive disease in 16 patients (31.4%). The overall response rate to capecitabine was 43.2%, which was consistent regardless of the site of metastasis. The median progression-free survival was seven months (95%.CI: 5.3 -8.8). The one and three-year survival rates were 79% and 53%, respectively. Capecitabine was generally tolerated, the most common grade I & II adverse events were hand-foot syndrome (HFS) in 9 patients (20.5%), fatigue in 8 patients (15.7%), Diarrhea in 6 patients (11.7%), anemia in 5 patients (9.8 %), thrombocytopenia in 4 patients (7.8%) and neutropenia in 2 patients (4.0%). The most common grade III & IV was HFS in 3 patients (6%) and fatigue in one patient (2%) that led to treatment discontinuation after the first cycle. Conclusions: Capecitabine in Recurrent/Metastatic NPC is an effective and well-tolerated oral agent; however, a randomized prospective trial to evaluate capecitabine efficacy in this setting still recommended.

Abstract Background: DNA hypomethylating agent, decitabine, has become the current standard therapy for patients with higher-risk myelodysplastic syndromes (MDS). Decitabine was launched in China in August 2009 without clinical trials. According to some retrospective studies, the efficacy and safety are similar to those reported in other countries, but there is still a lack of large-scale prospective clinical trials. So we start a prospective clinical trial in China to compare the effect and safety of decitabine in MDS, which was registered at clinicaltrials.gov (NCT02013102). Design: Adults with intermediate or high risk MDS by the International Prognostic Scoring System (IPSS≥0.5) were randomized to receive either decitabine 20 mg/m2 IV daily for 5 days (arm Ⅰ) or decitabine 12 mg/m2 IV daily for 8 days (arm Ⅱ) every four weeks. Patients continued to receive study drug for 4 cycles until death, disease progression, intercurrent illness preventing further administration of treatment, unacceptable adverse event or decision by the patient to withdraw from the study. And supportive care were permitted. The primary end point was overall response rate (ORR, CR+mCR+PR) by International Working Group (IWG 2006) criteria, secondary end points included CR, mCR, PR, HI, safety, et al. Results: We enrolled a total of 198 patients between 8/2013 and 12/2017, among which 7 patients didn't take decitabine, and 191 were included in the analysis. 94 in arm Ⅰ recieved decitabine and 97 in arm Ⅱ. 32.8% of patients withdrew from the study for a variety of reasons, including progression and death (5.1%), personal decision (13.6%), adverse events (6.6%), and other causes (7.6%). The median age of patients in arm Ⅰ was 54.88 years old and 54.82 years old in arm II. The median follow-up was 106 days for patients in both arms. The patients received a mean 2.5 cycles of decitabine therapy for arm Ⅰ and 2.0 cycles for arm Ⅱ. The overall response rate was 39.3% in total, and 41.5% and 38.1% (p=0.6598) for patients in arm Ⅰ and arm Ⅱ, respectively. And CR was 18.1% and 14.4% (p= 0.5584) , PR was 6.4% and 3.1% (p=0.3257) , mCR was 17.0% and 20.6% (p=0.5814) , HI was 3.2% and 1.0% (p=0.3633) , for patients in armⅠand armⅡ, respectively (Table 1). Among all patients, 38.7% were intermediate-1 risk, 40.3% were intermediate-2 risk, 20.4% were high risk. Analysis of response by MDS patient subtypes is shown in Table 2. Those who were higher risk experienced higher ORR and CR, while the difference is not significant between two arms (p>0.05). As expected, cytopenias were the most frequent complications (76.4%). Grade 3-4 neutropenia, thrombocytopenia and anemia considered to be at least possibly related to the study drug occurred at rates of 23.0%, 34.6%, and 34.6% of patients, respectively. Nonhematologic adverse events were also common including abnormal metabolism and nutrition (23.40% vs 18.56%), abnormal gastrointestinal function (29.79% vs 41.24%), cardiac disorders (11.70% vs 14.43%), infection and infectious diseases (32.98% vs 36.08%), abnormal skin and subcutaneous tissue and so on, which were no significant differences between two ams. During the study there were 17 SAE, only 7 cases were possibly related to drug therapy, such as pulmonary infection, Sepsis, myelosuppression, intracranial hemorrhage, hepatic failure, and arrhythmia. Conclusions: The use of 5-day and 8-day schedule decitabine is safe and effective in patients with intermediate and high risk MDS, among which there was no significant differences.
