RESUMO

RATIONALE: Cancer-related stroke has been regarded as an emerging subtype of ischemic event. Acute treatment for this subtype may include the antiplatelet agents, anticoagulants, or endovascular intervention. PATIENT CONCERNS: A 63-year-old woman with sudden-onset right hemiparesis and conscious change was sent to our emergency department. The patient had underlying sigmoid adenocarcinoma and received chemotherapy FOLFIRI (FOL, folinic acid; F, fluorouracil; and IRI, irinotecan) with targeted therapy cetuximab following lower anterior resection since the diagnosis was made. DIAGNOSES: Brain magnetic resonance angiography revealed a filling defect in left carotid bulb, and neurosonography showed a thick atherosclerotic plaque (size 4.9 mm) in the left internal carotid artery on day 5 after the onset of stroke. INTERVENTIONS: During the first three hours after onset, administration of IV tissue plasminogen activator did not resolve the thrombus. Dabigatran (110 mg bid) started on day 7. OUTCOMES: The atherosclerotic plaque dissolved on day 24. The patient recovered her muscle strength but still had nonfluent speech in mild extent. LESSONS: Thrombolytic and anticoagulant medications in this patient suggested the thrombus formation with fibrin-rich content which may be attributable to both cancer and chemotherapy. Dabigatran, an oral anticoagulant, had a benefit for this subtype of ischemic stroke among patients with cancer.

RESUMO

RATIONALE: Drug-induced pancreatitis (DIP) is a kind of acute pancreatitis with a relatively low incidence. There are many cases of acute pancreatitis (AP) caused by chemotherapeutic agents that have been reported. However, few reports focus on the combination of chemotherapeutic agents that induce acute pancreatitis. This article aims to retrospectively analyze a case of DIP and to explore the relationship between chemotherapeutic agents and acute pancreatitis. PATIENT CONCERNS: Here, we report a 35-year-old Chinese female patient who was diagnosed as acute myeloid leukemia with BCR/ABL expression. After induction chemotherapy of daunorubicin and cytarabine, bone marrow aspiration showed: Acute myeloid leukemia-not relieved (AML-NR). Then the regimen of homoharringtonine, cytarabine and dasatinib was started. The patient developed abdominal pain on the 14th day of chemotherapy. Laboratory tests showed elevated serum amylase (AMY) and lipase (LIPA). Computed tomography (CT) of the abdomen revealed a swollen pancreas with blurred edges and thickened left prerenal fascia. DIAGNOSIS: The patient was diagnosed as DIP by the symptoms of upper abdominal pain and the change of CT images. Other common causes of AP were excluded meanwhile. INTERVENTIONS: The chemotherapy was stopped immediately. And after fasting, fluid infusion and inhibiting the secretion of the pancreas, the symptoms were relieved. OUTCOMES: DIP relapsed when the regimen of aclacinomycin + cytarabine + G-CSF + dasatinib regimen (G-CSF (400ug/day, day 1 to 15), cytarabine (30 mg/day, day 2 to 15), aclacinomycin (20 mg/day, day 2 to 5)and dasatinib (140 mg/day, continuously)) was given, and was recovered after treatment for AP was performed. LESSONS: To choose the best treatment plan for patients, clinicians should raise awareness of DIP, and should know that chemotherapeutic agents can induce pancreatitis and the combination of chemotherapeutic agents may increase the risk of drug-induced pancreatitis.

RESUMO

INTRODUCTION: FOLFOX therapy is the main chemotherapy regimen for colorectal cancer. Peripheral neuropathy, hematotoxicity, and digestive symptoms are known to be the most frequent adverse events. Hyperammonemia and lactic acidosis rarely occur simultaneously during treatment with FOLFOX therapy; the number of case reports is limited worldwide. We report a case of disturbance of consciousness, considered to be caused by hyperammonemia and lactic acidosis that occurred during treatment with mFOLFOX6 therapy that was administered as postoperative adjuvant treatment for rectal cancer. PATIENT CONCERNS: This case was of a 71-year-old man who had been receiving oral treatment for chronic kidney disease and diabetes mellitus. Laparoscopic low anterior resection and artificial anal construction surgery were performed for stage III rectal cancer. As adjuvant postoperative therapy, mFOLFOX6 therapy was started but was followed by a disturbance of consciousness. DIAGNOSES: Results of the blood tests revealed notable hyperammonemia (ammonia level, 1,163 µg/dl) and lactic acidosis (pH 7.207; lactate, 17.56 mmol/L); however, imaging diagnosis did not reveal intracranial lesions that could cause disturbance of consciousness. INTERVENTIONS: For hyperammonemia, branched-chain amino acid agents and Ringers solution supplementation were administered. For acidosis, 7% sodium hydrogen carbonate was administered as treatment. OUTCOMES: The disturbance of consciousness improved within 12 hours of initiating the treatment, and the patient was discharged with no sequelae on 7th day after hospitalization. CONCLUSION: In patients with chronic kidney disease, FOLFOX regimen may confer risks of hyperammonemia and lactic acidosis.

RESUMO

The induction therapy containing ixazomib, an oral proteasome inhibitor, has shown favorable efficacy and safety in clinical trials, but its experience in real-life remains limited. In routine practice, few patients received ixazomib-based induction therapy due to reasons including (1) patients' preference on oral regimens, (2) concerns on adverse events (AEs) of other intravenous/subcutaneous regimens, (3) requirements for less center visits, and (4) fears of COVID-19 and other infectious disease exposures. With the aim of assessing the real-life effectiveness and safety of ixazomib-based induction therapy, we performed this multi-center, observational study on 85 newly diagnosed multiple myeloma (NDMM) patients from 14 medical centers. Ixazomib-based regimens included ixazomib-lenalidomide-dexamethasone (IRd) in 44.7% of patients, ixazomib-dexamethasone (Id) in 29.4%, and Id plus another agent (doxorubicin, cyclophosphamide, thalidomide, or daratumumab) in 25.9%. Different ixazomib-based therapies were applied due to (1) financial burdens or limitations on local health insurance coverage, (2) concerns on treatment tolerance, and (3) drug accessibility issue. Ten patients received ixazomib maintenance. The median age was 67 years; 43.5% had ISS stage III disease; 48.2% had an Eastern Cooperative Oncology Group performance score ≥ 2; and 17.6% with high-risk cytogenetic abnormalities. Overall response rate for all 85 patients was 95.3%, including 65.9% very good partial response or better and 29.5% complete responses. The median time to response was 30 days. The response rate was similar across different ixazomib-based regimens. Median progression-free survival was not reached. Severe AEs (≥ grade 3) were reported in 29.4% of patients. No grade 3/4 peripheral neuropathy (PN) occurred. Patients received a median of 6 (range 1-20) cycles of ixazomib treatment; 56.6% remained on treatment at data cutoff; 15.3% discontinued treatment due to intolerable AEs. These results support that the ixazomib-based frontline therapy was highly effective with acceptable toxicity in routine practice and the ixazomib oral regimens could be good alternative options for NDMM patients.

RESUMO

Although treatment outcomes for diffuse large B cell lymphoma (DLBCL) have improved with the introduction of rituximab, approximately half of patients experience relapsed/refractory (r/r) disease. Furthermore, no standard salvage therapy has yet been established to date, while limitations in treatment options exist due to toxicity and restricted tolerability among elderly patients and/or those with comorbidities. The ICE (ifosfamide, cyclophosphamide, and etoposide) regimen is often used as salvage therapy for r/r DLBCL. Several modified ICE regimens not requiring continuous ifosfamide infusion are available, which can be used in outpatient clinics. This study analyzed the efficacy and toxicity of fractionated ICE with rituximab (f-R-ICE) as a salvage regimen among 47 patients with relapsed/refractory DLBCL (median age upon f-R-ICE initiation, 71 years). The whole cohort had an overall (ORR) and complete response rate of 53.1% (n = 25) and 25.5% (n = 12), respectively, and an estimated 1-year overall survival after f-R-ICE initiation of 57%. Comorbidities were evaluated using the Charlson Comorbidity Index (CCI) upon f-R-ICE initiation. Patients with low CCI scores (68%) had a higher ORR than those with high CCI scores (36.4%) upon f-R-ICE initiation (P = 0.042). In contrast, no significant differences in overall survival (OS) were observed between the low and high CCI groups (1-year OS 56.6% vs. 52.2%; median OS 24 vs. 22.8 months) after initiating f-R-ICE. Our results suggest that f-R-ICE is a safe and effective salvage therapy for r/r DLBCL and can be used for older patients and/or those with high CCI scores in outpatient clinics.

RESUMO

Because of the global coronavirus pandemic, the 2020 annual scientific meeting of the American Society of Clinical Oncology took place virtually, 29-30 May. At the meeting, results from key studies about the treatment of chronic lymphocytic leukemia (cll) were disseminated. Studies examined the efficacy and safety of ibrutinib, acalabrutinib, zanubrutinib, and venetoclax as monotherapy or in combination with novel agents for patients with treatment-naïve and relapsed or refractory cll. Our meeting report describes the foregoing studies and presents interviews with investigators and commentaries by Canadian hematologists about potential effects on Canadian practice.

RESUMO

BACKGROUND: Chemotherapy is the main therapy for stage IIIB/IV non-small cell lung cancer (NSCLC). However, the 5-year survival rate is 6%. Cancer Green Therapy is a novel therapy in China, which refers to cryoablation combined with traditional Chinese medicine (TCM) formula. Our previous retrospective analysis showed that patients with NSCLC had longer survival time and better quality of life after receiving cryoablation combined with TCM formula, compared with patients who received chemotherapy alone. METHODS: This study is a multicenter, randomized, controlled clinical study. The experiment will be carried out in 6 hospitals at the same time, and a total of 450 cases of participants will be randomly assigned to the experimental group and the control group (n = 225). The experimental group will be given cryoablation and 28-days TCM formula, and the control group will be given 4 cycles chemotherapy. After 30 months of follow-up, the efficacy and safety of cryoablation combines with TCM formula in patients with stage IIIB/IV NSCLC will be observed. The primary outcome is overall survival. The secondary outcomes include progression-free survival, objective response rate, and quality of life. We will also conduct a safety evaluation of the treatment at the end of the trial. DISCUSSION: This multicenter, randomized, controlled clinical study not only provides data on the efficacy and safety of cryoablation combined with TCM formula, but also provides a novel treatment strategy for clinicians and advanced NSCLC patients.

RESUMO

BACKGROUND: Venetoclax plus obinutuzumab has been established as a fixed-duration treatment regimen for patients with chronic lymphocytic leukaemia. We compared the long-term efficacy after treatment cessation of the combination of venetoclax plus obinutuzumab with chlorambucil plus obinutuzumab in patients with previously untreated chronic lymphocytic leukaemia. METHODS: CLL14 is a multicentre, randomised, open-label, phase 3 trial done at 196 sites in 21 countries. Eligible patients were aged 18 years or older, had untreated chronic lymphocytic leukaemia, and coexisting conditions with a cumulative illness rating scale greater than 6, a creatinine clearance of 30-69 mL/min, or both. Patients were randomly assigned (1:1) via a web and voicemail system with allocation concealment and based on a computer-generated randomisation schedule with a block size of six and stratified by Binet stage and geographical region. Patients received either venetoclax plus obinutuzumab (oral venetoclax initiated on day 22 of cycle 1 [28-day cycles], with a 5-week dose ramp-up [20 mg, 50 mg, 100 mg, and 200 mg, then 400 mg daily for 1 week], thereafter continuing at 400 mg daily until completion of cycle 12; combined with intravenous obinutuzumab for six cycles starting with 100 mg on day 1 and 900 mg on day 2 [or 1000 mg on day 1], 1000 mg on days 8 and day 15 of cycle 1, and subsequently 1000 mg on day 1 of cycles 2 through 6) or chlorambucil plus obinutuzumab (oral chlorambucil at 0·5 mg/kg bodyweight on days 1 and 15 of each cycle for 12 cycles combined with the same obinutuzumab regimen). The primary endpoint was investigator-assessed progression-free survival in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study treatment. Patient enrolment is complete, and the study is registered with ClinicalTrails.gov, NCT02242942. FINDINGS: Between Aug 7, 2015, and Aug 4, 2016, 432 patients were enrolled and randomly assigned to receive either venetoclax plus obinutuzumab (n=216) or chlorambucil plus obinutuzumab (n=216). All patients had been off treatment for at least 24 months at data collection. At a median follow-up of 39·6 months (IQR 36·8-43·0), patients given venetoclax plus obinutuzumab had a significantly longer progression-free survival than did patients given chlorambucil plus obinutuzumab (HR 0·31, 95% CI 0·22-0·44; p<0·0001). Median progression-free survival was not reached (95% CI not estimable to not estimable) in the venetoclax plus obinutuzumab group vs 35·6 months (33·7-40·7) in the chlorambucil plus obinutuzumab group. The most common grade 3 or 4 adverse event in both groups was neutropenia (112 [53%] of 212 patients in the venetoclax plus obinutuzumab group versus 102 [48%] of 214 patients in the chlorambucil plus obinutuzumab group). Serious adverse events occurred in 115 (54%) of 212 patients in the venetoclax plus obinutuzumab group and 95 (44%) of 214 patients in the chlorambucil plus obinutuzumab group. Venetoclax or chlorambucil treatment-related deaths were reported in one (1%) of 212 patients in the venetoclax plus obinutuzumab group (n=1 sepsis) and two (1%) of 214 patients in the chlorambucil plus obinutuzumab group (n=1 septic shock, n=1 metastatic skin squamous carcinoma). INTERPRETATION: 2 years after treatment cessation, venetoclax plus obinutuzumab continues to significantly improve progression-survival compared with chlorambucil plus obinutuzumab, thereby providing a limited duration treatment option for patients with previously untreated chronic lymphocytic leukaemia.

RESUMO

BACKGROUND: There is a strong unmet need to improve systemic therapy in mesothelioma. Chemotherapy with cisplatin and pemetrexed improves survival in malignant pleural mesothelioma, and immune checkpoint inhibitors are an emerging treatment in this disease. We aimed to evaluate the activity of durvalumab, an anti-PD-L1 antibody, given during and after first-line chemotherapy with cisplatin and pemetrexed in patients with advanced malignant pleural mesothelioma. METHODS: DREAM was a multicentre, single-arm, open-label, phase 2 trial done in nine hospitals in Australia. Eligible patients were aged 18 years or older and had histologically confirmed malignant pleural mesothelioma considered unsuitable for cancer-directed surgery, an Eastern Cooperative Oncology Group performance status of 0 or 1, and measurable disease as per the modified Response Evaluation Criteria in Solid Tumors version 1.0 (mRECIST) for mesothelioma that was previously untreated with systemic therapy. All histological subtypes were eligible. The first six participants were treated for two cycles in a safety run-in. All participants received cisplatin 75 mg/m2, pemetrexed 500 mg/m2, and durvalumab 1125 mg intravenously on day 1 of a 3-weekly schedule for a maximum of six cycles. Change from cisplatin to carboplatin with an area under the curve of 5 was permitted. Durvalumab was continued for a maximum of 12 months. The primary endpoint was progression-free survival at 6 months, measured according to mRECIST for malignant pleural mesothelioma and analysed in the intention-to-treat population. Safety analyses included all participants who receive at least one dose of any study drug. This study is registered with the Australia New Zealand Clinical Trials Registry, ACTRN12616001170415. FINDINGS: Between Dec 28, 2016, and Sept 27, 2017, 55 participants were enrolled. 54 patients were eligible and were followed up for a median of 28·2 months (IQR 26·5-30·2). 31 (57%; 95% CI 44-70) of 54 patients were alive and progression-free at 6 months. The most common grade 3-4 adverse events were neutropenia (seven [13%] patients), nausea (six [11%]), and anaemia (four [7%]). A total of 60 serious adverse events occurred in 29 participants, five of which were considered possibly related to durvalumab. Five patients died during the study treatment; none of these five deaths were attributed to study treatment. INTERPRETATION: The combination of durvalumab, cisplatin, and pemetrexed has promising activity and an acceptable safety profile that warrants further investigation in a randomised phase 3 trial.

RESUMO

BACKGROUND: Topotecan is currently the only drug approved in Europe in a second-line setting for the treatment of small-cell lung cancer. This study investigated whether the doublet of carboplatin plus etoposide was superior to topotecan as a second-line treatment in patients with sensitive relapsed small-cell lung cancer. METHODS: In this open-label, randomised, phase 3 trial done in 38 hospitals in France, we enrolled patients with histologically or cytologically confirmed advanced stage IV or locally relapsed small-cell lung cancer, who responded to first-line platinum plus etoposide treatment, but who had disease relapse or progression at least 90 days after completion of first-line treatment. Eligible patients were aged 18 years or older and had an Eastern Cooperative Oncology Group performance status 0-2. Enrolled patients were randomly assigned (1:1) to receive combination carboplatin plus etoposide (six cycles of intravenous carboplatin [area under the curve 5 mg/mL per min] on day 1 plus intravenous etoposide [100 mg/m2 from day 1 to day 3]) or oral topotecan (2·3 mg/m2 from day 1 to day 5, for six cycles). Randomisation was done using the minimisation method with biased-coin balancing for ECOG performance status, response to the first-line chemotherapy, and treatment centre. The primary endpoint was progression-free survival, which was centrally reviewed and analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT02738346. FINDINGS: Between July 18, 2013, and July 2, 2018, we enrolled and randomly assigned 164 patients (82 in each study group). One patient from each group withdrew consent, therefore 162 patients (81 in each group) were included in the intention-to-treat population. With a median follow-up of 22·7 months (IQR 20·0-37·3), median progression-free survival was significantly longer in the combination chemotherapy group than in the topotecan group (4·7 months, 90% CI 3·9-5·5 vs 2·7 months, 2·3-3·2; stratified hazard ratio 0·57, 90% CI 0·41-0·73; p=0·0041). The most frequent grade 3-4 adverse events were neutropenia (18 [22%] of 81 patients in the topotecan group vs 11 [14%] of 81 patients in the combination chemotherapy group), thrombocytopenia (29 [36%] vs 25 [31%]), anaemia (17 [21%] vs 20 [25%]), febrile neutropenia (nine [11%] vs five [6%]), and asthenia (eight [10%] vs seven [9%]). Two treatment-related deaths occurred in the topotecan group (both were febrile neutropenia with sepsis) and no treatment-related deaths occurred in the combination group. INTERPRETATION: Our results suggest that carboplatin plus etoposide rechallenge can be considered as a reasonable second-line chemotherapy option for patients with sensitive relapsed small-cell lung cancer.

RESUMO

BACKGROUND: No standard treatment exists for advanced chordoma. Apatinib has been found to have promising efficacy and manageable adverse effects for the treatment of solid tumours. We aimed to investigate the safety and antitumour activity of apatinib in patients with advanced chordoma. METHODS: We did a single-arm, phase 2 study at one tertiary hospital in Shanghai, China. Eligible patients were aged 18-75 years, with histologically confirmed advanced chordoma that was unresectable or resectable only through demolitive surgery, who had previously received surgical treatment, with at least one measurable lesion according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, evidence of tumour progression on enhanced CT or MRI in the previous 6 months, and an Eastern Cooperative Oncology Group performance status of 0-2. Patients received oral 500 mg apatinib once daily until disease progression or unacceptable toxicity. The co-primary endpoints were progression-free survival and objective response rate according to RECIST 1.1 and Choi criteria by investigator assessment. Progression-free survival was assessed in the intention-to-treat population. Objective response rate was assessed in the per-protocol population, which included all enrolled patients who were compliant with the protocol and had at least one post-baseline assessment. Safety was analysed in all patients with complete safety data. This study is ongoing, but recruitment is complete. This study is registered with Chictr.org.cn, ChiCTR-OIC-17013586. FINDINGS: Between Aug 21, 2017, and May 31, 2019, we screened 32 patients, of whom 30 were enrolled. Median follow-up was 14·2 months (IQR 9·4-19·7). Of the 27 patients included in the per-protocol population, one patient (3·7%; 95% CI 0-11·3) achieved an objective response according to RECIST, and seven patients (25·9%; 8·3-43·6) achieved an objective response according to Choi criteria. Median progression-free survival was 18 months (95% CI 3-34) according to RECIST and 18 months (3-33) according to Choi criteria. The most common treatment-related grade 3 adverse events were hypertension (seven [24%] of 29 patients) and proteinuria (two [7%]). No treatment-related grade 4 adverse events or treatment-related deaths were observed. INTERPRETATION: To our knowledge, this is the first trial of apatinib for the treatment of advanced chordoma. Apatinib shows promising activity and manageable toxicity and thus might be an option for the treatment of advanced chordoma. FUNDING: None.

RESUMO

Lenalidomide (Len) and dexamethasone (dex) therapy is a standard therapy in patients with multiple myeloma. Elderly or unfit patients may reduce Len or dex doses to prevent toxicities that lead to treatment discontinuation. However, there have been few studies evaluating the efficacy and safety of lower doses of Len and dex. We conducted a phase II study of 1.5-year low-dose Len and dex therapy following melphalan and prednisolone (MP), the number of which cycles was determined by a response within 9 cycles. The Len dose was 10 mg daily and the dex dose was 20 mg weekly, which were continued for 1.5 years. Twenty-one patients were enrolled. The median number of cycles of MP was 3 (range, 2-9). The overall response rate was 81% and a very good partial response or better was achieved in 33.3% of patients. The median follow-up time for survivors was 70.5 months (range, 42-83 months), the median progression-free survival (PFS) was 27 months (95% CI, 21-33 months), and the median overall survival was not reached. Grade 3 or 4 adverse events were observed in 28.6% of patients. In conclusion, the low-dose Len and dex therapy safely achieved comparable efficacies to the standard-dose regimen in elderly patients with newly diagnosed multiple myeloma. UMIN000007889.

RESUMO

Concurrent cisplatin-based chemotherapy and radiotherapy (CCRT) plus brachytherapy is standard treatment for locally advanced cervical cancer. Platinum-based neoadjuvant chemotherapy (NACT) followed by radical hysterectomy has been proposed as an alternative approach, especially for patients with stage Ib2-IIb disease. This review analyzes the most commonly used combination regimens in this clinical setting and the randomized trials comparing chemo-surgery versus definitive radiotherapy or CCRT. The combination of paclitaxel plus ifosfamide plus cisplatin (TIP regimen) obtained the highest rates of optimal pathological response, associated with elevated hematological toxicity. In a recent phase II study, a dose-dense regimen consisting of weekly paclitaxel plus carboplatin for 9 cycles has achieved optimal pathological response rates similar to those of TIP with better toxicity profile. Further studies are strongly warranted to better define the optimal regimen for the patients selected to receive NACT followed by radical surgery.

RESUMO

BACKGROUND/AIM: Adult T-cell leukemia/lymphoma (ATLL) is a relatively refractory CD4-positive peripheral T-cell lymphoma. VCAP-AMP-VECP (mLSG15) is one of the standard chemotherapeutic regimens for patients with aggressive ATLL. Mogamulizumab (moga), a monoclonal antibody for C-C chemokine receptor 4 antigen expressed on the cell surface, has recently been poised for use as monotherapy and in combination with chemotherapy. However, to date, a significant survival benefit has not been obtained with the combination of moga + mLSG15 therapy. PATIENTS AND METHODS: We retrospectively analyzed 77 patients diagnosed with aggressive ATLL. Of them, 22 were treated with moga + a chemotherapy regimen comprised of etoposide, vincristine, doxorubicin, cyclophosphamide, and prednisolone (EPOCH), 16 with moga + mLSG15, and 39 with chemotherapy alone. RESULTS: A risk reduction of approximately 30% was obtained with moga + EPOCH compared with moga + mLSG15. CONCLUSION: The addition of moga to chemotherapy did not result in a survival benefit compared with chemotherapy alone. However, a statistically significant overall survival benefit was observed in patients with moga-induced skin disorders.

RESUMO

BACKGROUND: Treatment for platinum-resistant ovarian cancer is difficult and challenging because available chemotherapeutic agents only offer short survival improvements. The efficacy of re-treatment with platinum-based agents including nedaplatin for platinum-resistant patients has not been fully investigated. CASE REPORT: We describe herein three cases of heavily treated platinum-resistant ovarian cancer that were successfully treated with weekly nedaplatin followed by olaparib. After becoming platinum-resistant, the cases were treated with non-platinum chemotherapies. Following these regimens, weekly nedaplatin was introduced, followed by olaparib. At the time of writing, survival since the start of weekly nedaplatin was 30 months for case 1, 20 months for case 2, and 17 months for case 3, with all patients showing no evidence of disease. CONCLUSION: Weekly nedaplatin followed by olaparib might represent a good treatment option for platinum-resistant ovarian cancer and is a solid candidate for further evaluation.

RESUMO

BACKGROUND/AIM: The treatment of patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) has remained challenging. The effect of salvage chemotherapy (SCT) after nivolumab has been identified recently in other cancer types. The aim of this study was to examine the efficacy of SCT after nivolumab treatment in patients with R/M HNSCC. PATIENTS AND METHODS: A retrospective study was conducted at four institutions in Japan. Fifty-six patients were enrolled in the study. RESULTS: The overall survival (OS) in SCT patients was significantly longer than that in best supportive care (BSC) patients. In the SCT patients, the median OS, median progression-free survival (PFS) and objective response rate (ORR) were 7.3 months, 2.3 months and 36%, respectively. Prognostic factor for OS and ORR was performance score (PS) and previous radiation, respectively. CONCLUSION: SCT after nivolumab is associated with better clinical outcomes in patients with R/M HNSCC compared to those receiving BSC.

RESUMO

BACKGROUND: To assess the prophylactic efficacy of postoperative single intravesical instillation with pirarubicin (THP) and mitomycin C (MMC) for low-risk non-muscle-invasive bladder cancer (NMBC). PATIENTS AND METHODS: A total of 103 clinically low-risk NMBC patients were preoperatively randomized into either THP (n=49) or MMC (n=54) groups. The primary endpoint was recurrence-free survival. RESULTS: The median follow-up periods of the THP and MMC groups were 955 and 1008 days, respectively (p=0.76). Twelve patients (24.5%) in the THP group and 7 (13%) in the MMC group had bladder cancer recurrences. The two-year recurrence-free survival of the THP group and the MMC group was 77.8% and 86.4%, respectively (p=0.20). Neither groups had severe toxicity. CONCLUSION: In low-risk NMBC, the prophylactic effect against postoperative single intravesical instillation with THP was not superior to that with MMC.

RESUMO

For patients with locoregionally advanced nasopharyngeal carcinoma (NPC), induction chemotherapy (IC) regimens based on TPF (docetaxel, cisplatin, and 5-fluorouracil), TP (docetaxel and cisplatin), and GP (gemcitabine and cisplatin) have shown excellent survival outcomes as the first-line therapy; however, no trials comparing the efficacy and safety of TPF, TP, and GP have been reported. We report 2 phase II trials comparing the treatment outcomes and side effects of 3 different IC regimens followed by concurrent chemoradiotherapy in locoregionally advanced patients with NPC.A total of 206 locoregionally advanced patients with NPC treated with a combination treatment from January 2012 to January 2014 were enrolled in the 2 studies. The patients received TPF-, TP-, and GP-based IC regimens every 3 weeks, followed by intensity-modulated radiotherapy and concurrent therapy with cisplatin every 3 weeks.After a median follow-up duration of 47 months (10-60 months), the 3-year local recurrence-free survival, regional recurrence-free survival, distant metastases-free survival, progression-free survival, and overall survival rates were 96.4%, 100%, 87.7%, 86%, and 94.7% in the TPF arm; 91.7%, 95.9%, 91.9%, 85.2%, and 92% in the TP arm; 98.6%, 100%, 89.0%, 87.6%, and 89.2% in the GP arm. The survival differences among the 3 arms were not statistically significant (P > .05). The multivariate analysis demonstrated that the IC regimen was not an independent prognostic factor for any survival outcomes. The patients in the TP arm experienced significantly lower grade 3/4 toxicities than the patients in the other 2 arms.TP-based IC regimen has similar efficacy compared with TPF- and GP-based IC regimens; however, TP-based IC regimen has a lower toxicity profile.

RESUMO

BACKGROUND: The incidence and mortality of colorectal cancer are high. Chemotherapy is currently the commonly used therapeutic scheme, but there are drug resistance and toxic and side effects. Kanglaite (KLT) injection is a broad-spectrum anticancer drug extracted from Semen Coicis (Yi Yi Ren), which has been widely used in the treatment of colorectal cancer. Clinical practice shows that KLT injection combined with chemotherapy has certain therapeutic advantages, but there is a lacking of evidence of evidence-based medicine. The purpose of this study is to systematically investigate the efficacy and safety of KLT injection combined with chemotherapy in the treatment of colorectal cancer. METHODS: Randomized controlled trials of KLT injection combined with chemotherapy in the treatment of colorectal cancer were retrieved from English databases (PubMed, Embase, Web of Science, the Cochrane Library) and Chinese databases (China National Knowledge Infrastructure, Wanfang, Chongqing VIP Chinese Science and Technology Periodical Database, Chinese Biological and Medical database), as well as searching Baidu academic and Google academic manually, and the retrieval time was from their establishment to August 2020. Two researchers independently conducted data extraction and literature quality evaluation on the quality of the included literatures, and meta-analysis was conducted on the included literatures using RevMan 5.3 (developed by the UK's International Cochrane Collaboration). RESULTS: This study assessed the efficacy and safety of KLT injection combined with chemotherapy in the treatment of colorectal cancer by effective rate, Karnofsky Performance Status, Carcinoemybryonic Angtigen remission rate, pain remission rate, and incidence of adverse reactions etc. CONCLUSIONS:: This study will provide reliable evidence-based evidence for the clinical application of KLT injection combined with chemotherapy in the treatment of colorectal cancer. ETHICS AND DISSEMINATION: The private information from individuals will not be published. This systematic review also will not involve endangering participant rights. Ethical approval is not required. The results may be published in a peer-reviewed journal or disseminated in relevant conferences. OSF REGISTRATION NUMBER: DOI 10.17605/OSF.IO/EKVAF.

RESUMO

BACKGROUND: The efficacy and safety of the anti-programmed death ligand 1 (PD-L1) monoclonal antibody atezolizumab, as compared with those of platinum-based chemotherapy, as first-line treatment for patients with metastatic non-small-cell lung cancer (NSCLC) with PD-L1 expression are not known. METHODS: We conducted a randomized, open-label, phase 3 trial involving patients with metastatic nonsquamous or squamous NSCLC who had not previously received chemotherapy and who had PD-L1 expression on at least 1% of tumor cells or at least 1% of tumor-infiltrating immune cells as assessed by the SP142 immunohistochemical assay. Patients were assigned in a 1:1 ratio to receive atezolizumab or chemotherapy. Overall survival (primary end point) was tested hierarchically according to PD-L1 expression status among patients in the intention-to-treat population whose tumors were wild-type with respect to EGFR mutations or ALK translocations. Within the population with EGFR and ALK wild-type tumors, overall survival and progression-free survival were also prospectively assessed in subgroups defined according to findings on two PD-L1 assays as well as by blood-based tumor mutational burden. RESULTS: Overall, 572 patients were enrolled. In the subgroup of patients with EGFR and ALK wild-type tumors who had the highest expression of PD-L1 (205 patients), the median overall survival was longer by 7.1 months in the atezolizumab group than in the chemotherapy group (20.2 months vs. 13.1 months; hazard ratio for death, 0.59; P = 0.01). Among all the patients who could be evaluated for safety, adverse events occurred in 90.2% of the patients in the atezolizumab group and in 94.7% of those in the chemotherapy group; grade 3 or 4 adverse events occurred in 30.1% and 52.5% of the patients in the respective groups. Overall and progression-free survival favored atezolizumab in the subgroups with a high blood-based tumor mutational burden. CONCLUSIONS: Atezolizumab treatment resulted in significantly longer overall survival than platinum-based chemotherapy among patients with NSCLC with high PD-L1 expression, regardless of histologic type.
