Abstract
Early results of the randomized placebo-controlled SORAML trial showed that, in patients with newly diagnosed acute myeloid leukaemia (AML), sorafenib led to a significant improvement in event-free (EFS) and relapse-free survival (RFS). In order to describe second-line treatments and their implications on overall survival (OS), we performed a study after a median follow-up time of 78 months. Newly diagnosed fit AML patients aged ≤60 years received sorafenib (n = 134) or placebo (n = 133) in addition to standard chemotherapy and as maintenance treatment. The 5-year EFS was 41 versus 27% (HR 0.68; p = 0.011) and 5-year RFS was 53 versus 36% (HR 0.64; p = 0.035). Allogeneic stem cell transplantation (allo SCT) was performed in 88% of the relapsed patients. Four years after salvage allo SCT, the cumulative incidence of relapse was 54 versus 35%, and OS was 32 versus 50%. The 5-year OS from randomization in all study patients was 61 versus 53% (HR 0.82; p = 0.282). In conclusion, the addition of sorafenib to chemotherapy led to a significant prolongation of EFS and RFS. Although the OS benefit did not reach statistical significance, these results confirm the antileukaemic activity of sorafenib.

Abstract
PURPOSE In REFLECT, lenvatinib demonstrated an effect on overall survival (OS) by confirmation of noninferiority to sorafenib in unresectable hepatocellular carcinoma. This analysis assessed correlations between serum or tissue biomarkers and efficacy outcomes from REFLECT. EXPERIMENTAL DESIGN Serum biomarkers (VEGF, ANG2, FGF19, FGF21, and FGF23) were measured by ELISA. Gene expression in tumor tissues was measured by the nCounter PanCancer Pathways Panel. Pharmacodynamic changes in serum biomarker levels from baseline, and associations of clinical outcomes with baseline biomarker levels, were evaluated. RESULTS Four hundred and seven patients were included in the serum analysis set (lenvatinib n = 279, sorafenib n = 128); 58 patients were included in the gene-expression analysis set (lenvatinib n = 34, sorafenib n = 24). Both treatments were associated with increases in VEGF; only lenvatinib was associated with increases in FGF19 and FGF23 at all time points. Lenvatinib-treated responders had greater increases in FGF19 and FGF23 versus nonresponders at cycle 4, day 1 (FGF19: 55.2% vs. 18.3%, P = 0.014; FGF23: 48.4% vs. 16.4%, P = 0.0022, respectively). Higher baseline VEGF, ANG2, and FGF21 correlated with shorter OS in both treatment groups. OS was longer for lenvatinib than sorafenib [median, 10.9 vs. 6.8 months, respectively; HR, 0.53; 95% confidence interval (CI), 0.33-0.85; P-interaction = 0.0397] with higher baseline FGF21. In tumor tissue biomarker analysis, VEGF/FGF-enriched groups showed improved OS with lenvatinib versus the intermediate VEGF/FGF group (HR, 0.39; 95% CI, 0.16-0.91; P = 0.0253). CONCLUSIONS Higher baseline levels of VEGF, FGF21, and ANG2 may be prognostic for shorter OS. Higher baseline FGF21 may be predictive for longer OS with lenvatinib compared with sorafenib, but this needs confirmation.

Abstract
PURPOSE To evaluate the feasibility and potential efficacy of nanocurcumin supplementation in patients with localized muscle-invasive bladder cancer (MIBC) undergoing induction chemotherapy. MATERIALS AND METHODS In this double-blind, placebo-controlled trial, 26 MIBC patients were randomized to receive either nanocurcumin (180 mg/day) or placebo during the course of chemotherapy. All patients were followed up to four weeks after the end of treatment to assess the complete clinical response to the chemotherapy as primary endpoint. Secondary endpoints were the comparisons of chemotherapy-induced nephrotoxicity, hematologic nadirs, and toxicities between the two groups. Hematologic nadirs and toxicities were assessed during the treatment. RESULTS Nanocurcumin was well tolerated. The complete clinical response rates were 30.8 and 50% in the placebo and nanocurcumin groups, respectively. Although nanocurcumin was shown to be superior to placebo with respect to complete clinical response rates as the primary endpoint, there was no significant difference between the groups (p = 0.417). No significant difference was also found between the two groups with regard to grade 3/4 renal and hematologic toxicities as well as hematologic nadirs. CONCLUSION These preliminary data indicate the feasibility of nanocurcumin supplementation as a complementary therapy in MIBC patients and support further larger studies. Moreover, a substantial translational insight to fill the gap between the experiment and clinical practice in the field is provided.

Abstract
Oral mucositis is a common and distressing complication in patients receiving high-dose chemotherapy followed by hematopoietic stem cell transplantation (HSCT). We reported previously in a single-center retrospective analysis that zinc-L-carnosine (polaprezinc [PZ]) reduced the incidence of oral mucositis associated with HSCT. To verify the accuracy of the prophylactic effect of PZ against oral mucositis, we carried out a multi-institutional prospective randomized controlled study. Patients were randomly allocated to either the prevention group, in which PZ lozenge treatment was started before chemotherapy, or the control group, in which administration of PZ lozenges was initiated immediately after the onset of Grade 2 oral mucositis. Oral mucositis was evaluated daily from the start of chemotherapy to 35 days after transplantation. A total of 91 patients were enrolled, and 88 patients (47 in the control group and 41 in the prevention group) were eligible for data analysis. The incidence of Grade ≥2 but not Grade ≥3 oral mucositis was significantly reduced in the prevention group compared to the control group (44.7% in control group vs 22.0% in the prevention group, P = .025). There were no significant differences in the incidence rates of other adverse events or the rate of engraftment (95.6% vs 97.2%, P = .693) between the two groups. These findings suggest that PZ lozenge is effective for prophylaxis against Grade ≥2 oral mucositis associated with chemotherapy in patients undergoing HSCT without any influence on the HSCT outcome.

Asian Pacific journal of cancer prevention : APJCP. 2021;(1):139-143
Abstract
OBJECTIVE One of the important treatments for cervical cancer is radiation therapy. This study sought to determine the role of curcumin as a radio-sensitizing agent for use with radiation therapy for cervical cancer. To accomplish this, we assessed the levels of survivin, which is an anti-apoptotic protein that plays a role in cell division and apoptosis inhibition. METHOD This study used a quasi-experimental design, including a pretest-posttest control group design approach. The study subjects included cervical carcinoma stage IIB-IIIB patients who were scheduled to undergo surgery at the Hasan Sadikin Hospital Bandung during the research period. The advanced cervical cancer patients were assigned to two groups: i) those who received curcumin + radiation therapy and ii) those who received placebo + radiation therapy. RESULTS In the group treated with curcumin + radiation, 15 (75%) patients showed decreased survivin levels and 5 (25%) showed increased survivin levels. Whereas, in the placebo + radiation group, there were 8 (40%) patients who showed decreased survivin levels and 12 (60%) who showed increased survivin levels. CONCLUSION In conclusion, curcumin is an effective, alternative radiosensitizer agent for application in cervical cancer treatment.

Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE The Carapa guianensis Aubl, popularly known as andiroba, is a large tree of the Meliaceae family, commonly found in the Amazon region. The oil extracted from its seeds is recognized in traditional medicine and has high anti-inflammatory and analgesic potential, which are the basic prerequisites for a therapeutic agent that can be used in the treatment of oral mucositis (OM). Moreover, the aforementioned oil has antimicrobial, antiallergic, and parasiticidal actions and is effective in the management of cutaneous and muscular dysfunctions. AIM OF THE STUDY To evaluate the therapeutic effects of andiroba gel (Carapa guianensis Aubl) on the symptomatology and evolution of OM in children with leukemia who underwent chemotherapy and to compare it to the effects of low power laser. MATERIALS AND METHODS This randomized, double-blind clinical trial involved 60 patients of both genders with leukemia, with age ranging from six to twelve years. The patients were divided into two study groups: the andiroba group (n = 30) and the laser group (n = 30). The level of pain experienced by the patients was assessed using the Wong-Baker visual analog scale and the degree of severity of OM was assessed using a table, recommended by the World Health Organization, that depicts the degrees of severity of OM. The data obtained were analyzed using the Mann-Whitney test, with statistical significance indicated by a P value less than or equal to 0.05. RESULTS A statistically significant reduction in the degree of OM was observed on the fourth, fifth, and sixth days and in the pain scores on the second, third, and fourth days in the andiroba group after the manifestation of OM, compared to the laser group. CONCLUSIONS The use of andiroba oil effectively reduced the severity of OM and relieved pain, which resulted in a decrease in the severity of signs and symptoms in the patients in the andiroba group, compared to the laser group.

Abstract
BACKGROUND The optimal preoperative treatment for locally advanced pancreatic cancer is unknown. We aimed to compare the efficacy and safety of nab-paclitaxel plus gemcitabine with nab-paclitaxel plus gemcitabine followed by fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) as multidrug induction chemotherapy regimens in locally advanced pancreatic cancer. METHODS In this open-label, multicentre, randomised phase 2 study, done at 28 centres in Germany, eligible patients were adults (aged 18-75 years) with an Eastern Cooperative Oncology Group performance status of 0 or 1 and histologically or cytologically confirmed, treatment-naive locally advanced pancreatic adenocarcinoma, as determined by local multidisciplinary team review. After two cycles of nab-paclitaxel 125 mg/m2 plus gemcitabine 1000 mg/m2 (administered intravenously on days 1, 8, and 15 of each 28-day cycle), patients without progressive disease or unacceptable adverse events were randomly assigned (1:1) to receive either two additional cycles of nab-paclitaxel plus gemcitabine (nab-paclitaxel plus gemcitabine group) or four cycles of sequential FOLFIRINOX (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, irinotecan 180 mg/m2, fluorouracil 400 mg/m2 by intravenous bolus followed by a continuous intravenous infusion of 2400 mg/m2 for 46 h on day 1 of each 14-day cycle; sequential FOLFIRINOX group). Randomisation was done by the clinical research organisation on request of the trial centre using a permuted block design (block size 2 and 4). Patients, investigators, and study team members were not masked to treatment allocation. The primary endpoint was surgical conversion rate (complete macroscopic tumour resection) in the randomised population by intention-to-treat analysis, which was assessed by surgical exploration in all patients with at least stable disease after completion of induction chemotherapy. This trial is registered with ClinicalTrials.gov, NCT02125136. FINDINGS Between Nov 18, 2014, and April 27, 2018, 168 patients were registered and 130 were randomly assigned to either the nab-paclitaxel plus gemcitabine group (64 patients) or the sequential FOLFIRINOX group (66 patients). Surgical exploration after completed induction chemotherapy was done in 40 (63%) of 64 patients in the nab-paclitaxel plus gemcitabine group and 42 (64%) of 66 patients in the sequential FOLFIRINOX group. 23 patients in the nab-paclitaxel plus gemcitabine group and 29 in the sequential FOLFIRINOX group had complete macroscopic tumour resection, yielding a surgical conversion rate of 35·9% (95% CI 24·3-48·9) in the nab-paclitaxel plus gemcitabine group and 43·9% (31·7-56·7) in the sequential FOLFIRINOX group (odds ratio 0·72 [95% CI 0·35-1·45]; p=0·38). At a median follow-up of 24·9 months (95% CI 21·8-27·6), median overall survival was 18·5 months (95% CI 14·4-21·5) in the nab-paclitaxel plus gemcitabine group and 20·7 months (13·9-28·7) in the sequential FOLFIRINOX group (hazard ratio 0·86 [95% CI 0·55-1·36]; p=0·53). All other secondary efficacy endpoints, such as investigator-assessed progression-free survival, radiographic response rate, CA 19-9 response rate, and R0 resection rate, were not significantly different between the two treatment groups except for improved histopathological downstaging in evaluable resection specimens from the sequential FOLFIRINOX group (ypT1/2 stage: 20 [69%] of 29 patients in the sequential FOLFIRINOX group vs four [17%] of 23 patients in the nab-paclitaxel plus gemcitabine group, p=0·0003; ypN0 stage: 15 [52%] of 29 patients in the sequential FOLFIRINOX group vs four [17%] of 23 patients in the nab-paclitaxel plus gemcitabine group, p=0·02). Grade 3 or higher treatment-emergent adverse events during induction chemotherapy occurred in 35 (55%) of 64 patients in nab-paclitaxel plus gemcitabine group and in 35 (53%) of 66 patients in the sequential FOLFIRINOX group. The most common of which were neutropenia (18 [28%] in nab-paclitaxel plus gemcitabine group, 16 [24%] in the sequential FOLFIRINOX group), nausea and vomiting (two [3%] in nab-paclitaxel plus gemcitabine group, eight [12%] in the sequential FOLFIRINOX group), and bile duct obstruction with cholangitis (six [9%] in nab-paclitaxel plus gemcitabine group, seven [11%] in the sequential FOLFIRINOX group). No deaths were caused by treatment-related adverse events during the induction chemotherapy phase. INTERPRETATION Our findings suggest that nab-paclitaxel plus gemcitabine is similarly active and safe as nab-paclitaxel plus gemcitabine followed by FOLFIRINOX as multidrug induction chemotherapy regimens for locally advanced pancreatic cancer. Although conversion to resectability was achieved in about a third of patients, additional evidence is required to determine whether this translates into improved overall survival. FUNDING Celgene.

Abstract
Despite the high cure probability for acute promyelocytic leukaemia (APL), a minority of patients will relapse and the risk factors for relapse are unclear. We retrospectively analysed 212 patients who were diagnosed with non-high-risk APL and received all-trans retinoic acid (ATRA) plus arsenic as front-line therapy at Peking University Institute of Hematology from February 2014 to December 2018. A total of 176 patients (83%) received oral arsenic (realgar-indigo naturalis formula) plus ATRA, 36 patients (17%) received arsenic trioxide plus ATRA and 203 patients were evaluable for relapse. After a median (range) follow-up of 53·6 (24·3-85·4) months, two patients had molecular relapse and eight had haematological relapse. A promyelocytic leukaemia/retinoic acid receptor alpha (PML-RARA) transcript level of ≥6·5% at the end of induction therapy was associated with relapse (P = 0·031). The 5-year cumulative incidence of relapse, event-free survival and overall survival were 5·5%, 92·3% and 96·3% respectively. In conclusion, the present long-term follow-up study further confirmed the high cure probability of ATRA plus oral arsenic as front-line therapy for non-high-risk APL and showed that the PML-RARA transcript level at the end of induction therapy was associated with relapse.

Heiba, MA, Ismail, SS, Sabry, M, Bayoumy, WAE, Kamal, KA
Cancer chemotherapy and pharmacology. 2021;(6):931-939
Abstract
PURPOSE Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of chemotherapy. Several trials have evaluated the protective effect of vitamin E in preventing CIPN with controversial results. This study aims to outline the role of vitamin E in preventing CIPN. METHODS A prospective phase II, open-label randomized controlled study was conducted in patients receiving taxane-based chemotherapy in Ain Shams University Hospitals, using vitamin E at a dose of 400 mg twice daily. The primary endpoint was the incidence of grade ≥ 2 sensory neuropathy according to CTCAE v 5.0 in each treatment arm. Secondary endpoints include time to onset and the duration of grade ≥ 2 sensory neuropathy. RESULTS A total of 140 patients were randomized between the control and vitamin E arms. There was no difference in the incidence of grade ≥ 2 sensory neuropathy between the two arms (25.7% in each arm; P = 1.0), as well as the time to onset of neuropathy (P = 0.24). However, there was a statistically significant difference between the 2 arms as regards the duration of neuropathy. The median duration was 12.5 vs. 5 weeks in the control and vitamin E arms respectively (P = 0.01). CONCLUSION Our study did not demonstrate a protective role of vitamin E in decreasing the incidence of CIPN in patients receiving taxane-based chemotherapy. However, the recovery from CIPN was much better as compared to the control arm, which may indicate a role for vitamin E in decreasing the duration and severity of CIPN.

Abstract
PURPOSE Lenvatinib has shown efficacy in treating radioiodine-refractory differentiated thyroid cancer (RR-DTC) in the multinational phase III SELECT study; however, it has not been tested in Chinese patients with RR-DTC. PATIENTS AND METHODS Chinese patients with confirmed RR-DTC (n = 151) were randomly assigned 2:1 to receive lenvatinib 24 mg/day or placebo in 28-day cycles. The primary endpoint was progression-free survival, and key secondary endpoints included objective response rate and safety. Analyses for progression-free survival and objective response rate were conducted using Response Evaluation Criteria in Solid Tumors v1.1 and confirmed by independent imaging review. All adverse events were assessed and monitored. RESULTS Progression-free survival was significantly longer with lenvatinib treatment [n = 103; median 23.9 months; 95% confidence interval (CI), 12.9-not estimable] versus placebo (n = 48; median 3.7 months; 95% CI, 1.9-5.6; hazard ratio = 0.16; 95% CI, 0.10-0.26; P < 0.0001). The objective response rate was 69.9% (95% CI, 61.0-78.8) in the lenvatinib arm and 0% (95% CI, 0-0) in the placebo arm. At data cutoff, 60.2% of patients receiving lenvatinib remained on treatment; treatment-emergent adverse events led to lenvatinib discontinuation in 8.7% of patients. Overall, treatment-emergent adverse events of grade ≥3 occurred in 87.4% of patients in the lenvatinib arm, the most common being hypertension (62.1%) and proteinuria (23.3%). CONCLUSIONS Lenvatinib at a starting dose of 24 mg/day significantly improved progression-free survival and objective response rate in Chinese patients with RR-DTC versus placebo. There were no new or unexpected toxicities. Results are consistent with those from SELECT involving patients with RR-DTC.
