Change of hand sensation and function in patients with malignant lymphoma during early-stage vincristine chemotherapy: A single-center observational study. Medicine (Baltimore) 2024; 103:e38207. [PMID: 38758870 PMCID: PMC11098250 DOI: 10.1097/md.0000000000038207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Accepted: 04/19/2024] [Indexed: 05/19/2024] Open
Abstract
This study aimed to investigate changes in hand sensation (finger tactile threshold and two-point discrimination) and function in patients with malignant lymphoma, particularly during the early stages of chemotherapy with vincristine. Eighteen patients with malignant lymphoma were enrolled in this study. Data on the Common Terminology Criteria for Adverse Events Version 4.0, the visual analog scale for hand numbness, the Semmes Weinstein monofilament test, static and moving two-point discrimination (2PD), grip strength, pinch strength, and the Purdue Pegboard test were collected at 3 time points: before the start of chemotherapy (T0), after the first cycle of chemotherapy (T1), and after the second cycle of chemotherapy (T2). No significant changes were observed in Semmes Weinstein monofilament test at T0, T1, or T2 in either hand. However, the static 2PD was significantly worse for the right ring, little, and left middle fingers, whereas the moving 2PD was significantly worse for the right ring, left index, middle, and ring fingers. Furthermore, the visual analog scale scores for hand numbness and left-hand grip strength worsened significantly. Right-hand grip strength, pinch strength of both hands, and Purdue Pegboard test showed no significant deterioration. Chemotherapy with vincristine may affect hand sensation and function in patients with malignant lymphoma by exacerbating finger 2PD and hand numbness. Additionally, during the early stages of vincristine chemotherapy, it is important to monitor for a decrease in grip strength specifically in the left hand.

Abstract
BACKGROUND Traditional dosing of chemotherapy drugs based on body surface area may overdose small dogs, leading to an increased frequency of adverse events (AEs). HYPOTHESIS/OBJECTIVES Evaluate the frequency of hematologic and gastrointestinal AEs in dogs with newly diagnosed lymphoma treated with vincristine weighing ≤15 kg in comparison to dogs weighing >15 kg. We hypothesized that dogs weighing ≤15 kg would experience a higher frequency of AEs. ANIMALS One hundred and thirty-eight dogs with newly diagnosed lymphoma were treated with vincristine. METHODS A multicenter retrospective study reviewing hematologic data and medical record information. Complete blood counts were performed no more than 24 hours before vincristine administration and then between 4 and 8 days post-administration. Data were evaluated using logistic regression or ordinal logistic regression. RESULTS Thirty-eight dogs weighing ≤15 kg and 100 dogs weighing >15 kg were included. The median vincristine dose for both groups was 0.6 mg/m2. Seventeen (12.3%) instances of neutropenia occurred with no significant difference in overall frequency or grade between groups. Thirty initially asymptomatic substage A dogs (29.4%) experienced gastrointestinal AEs. Because of the widespread use of gastrointestinal supportive care medications, statistical comparison between groups could not be performed. Seven instances of hospitalization occurred (5.0%) and the risk of hospitalization did not differ significantly between groups (P = .37). CONCLUSIONS AND CLINICAL IMPORTANCE Vincristine dosed at ≤0.6 mg/m2 does not increase the risk of hematologic AEs in dogs weighing ≤15 kg.

A prospective comparison study utilizing patient-reported outcomes of taxane-related peripheral neuropathy between nab-paclitaxel and standard paclitaxel in patients with breast cancer. Breast Cancer 2024; 31:409-416. [PMID: 38453739 DOI: 10.1007/s12282-024-01551-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Accepted: 02/04/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND: Characteristics of taxane-induced peripheral neuropathy (PN) could be different between paclitaxel and nab-paclitaxel. The purpose of this prospective observational multicenter cohort study was to compare tri-weekly nab-paclitaxel to weekly standard paclitaxel regarding the severity, onset and recovery of sensory and motor PN in patients with breast cancer. METHODS Patients with histologically confirmed breast cancer who were scheduled to receive standard weekly paclitaxel (80 mg/m2) or tri-weekly nab-paclitaxel (260 mg/m2) at institutions in our multicenter group were eligible for this study. Sensory and motor PN were evaluated every 3 weeks until PN improved for up to one year using patient-reported outcome. RESULTS Between February 2011 and April 2013, 115 patients were enrolled, including 57 and 58 in the paclitaxel and nab-paclitaxel groups, respectively. The incidence of moderate or severe sensory PN was not significantly different between the two groups (p = 0.40). The incidence of moderate or higher motor PN was more frequent in the nab-paclitaxel group than in the paclitaxel group (p = 0.048). The median period for demonstrating PN were shorter in the nab-paclitaxel group than in the paclitaxel group (sensory, p = 0.003; motor, p = 0.001). The recovery of motor PN was slower in the nab-paclitaxel group than in the paclitaxel group (p = 0.035), while the recovery period of sensory PN was not statistically different. CONCLUSION Nab-paclitaxel induced sensory PN sooner than paclitaxel, and no difference was observed in the severity and recovery duration between the two agents. Motor PN was more severe, started sooner, and improved over a longer period in the nab-paclitaxel-treated patients than in the paclitaxel-treated patients.

Abstract
BACKGROUND Paclitaxel hypersensitivity reactions (HSRs) are prevalent, especially in females. The common paclitaxel pretreatment, dexamethasone, may inhibit chemotherapy efficacy and accelerate tumor progression. We aimed to balance paclitaxel HSRs and the lowest dexamethasone dose for gynecologic malignancies. METHODS We retrospectively examined 1,074 cycles of 3-weekly paclitaxel-containing treatment for 231 gynecologic malignancies at Xiangya Hospital. HSR incidence with different dexamethasone regimens was the primary outcome. Risk factors were examined in all cycles using univariate and multivariate models with generalized estimating equations. A subgroup analysis of initial exposure to paclitaxel was also conducted. RESULTS HSR occurred in 33 patients (14.29%) and 49 cycles (4.56%), including 69.39% in cycles 1-2. There were no severe HSRs (grade ≥3). Different premedication regimens, including dexamethasone dosage and route, ranitidine presence or absence, didn't affect HSR incidence in univariate and multivariate analyzes (p > 0.05). Premenopausal women exerted fewer HSRs (ORadj 0.22, 95%CI 0.08-0.58; p = 0.002). At the first exposure to paclitaxel, more than 10 mg of dexamethasone didn't diminish HSRs (OR 0.83, 95%CI 0.27-2.59; p = 0.753). CONCLUSIONS In gynecologic malignancies, 10 mg dexamethasone along with 20 mg diphenhydramine may be adequate to prevent paclitaxel HSRs without ranitidine. It is necessary to reevaluate paclitaxel premedication regimens.

Abstract
BACKGROUND Rhabdomyosarcoma (RMS) is a rare cancer that develops in soft tissue, particularly skeletal muscle tissue and occasionally hollow organs like the bladder or uterus. Vincristine (VCR) is the main therapy used in treatment of RMS, it is an alkaloid produced from vinca and it is one of the most commonly prescribed drugs in pediatric oncology for the treatment of a number of tumors. The CYP3A5 enzyme is responsible for vincristine metabolism. The effect of CYP3A5 genetic polymorphism on the efficacy and toxicity of VCR on RMS patients still needs further research. METHODS Genotyping for CYP3A5 SNPs rs776746, rs10264272 and rs41303343 was performed using Taqman Real-Time PCR assays in a retrospective cohort study of 150 RMS pediatric patients treated with vincristine. The relationship between these genotypes and RMS survival was then examined. RESULTS We found that patients with CYP3A5*3/*3 had the highest incidence of vincristine-induced neuropathy reaching 61.3%. Patients with CYP3A5*1/*3, CYP3A5*3/*6 and the normal metabolizers with CYP3A5*1/*1 had frequencies of 22%, 10.7%, and 4.7%. patients with the lowest frequency of 1.3% were those with the CYP3A5*1/*6 genotype. There was no correlation between the genotypes of CYP3A5*3, CYP3A5*6, CYP3A5*7, and RMS survival. Initial risk, metastasis, response, convulsions, unsteady gait and hepatotoxicity grade had a significant effect on overall survival with p<0.05. CONCLUSION CYP3A5*1/*1 have less severe vincristine-induced neuropathy than CYP3A5 *1/*3, CYP3A5 *1/*6 and CYP3A5 *3/*3, CYP3A5 *3/*6. There is a significant influence of CYP3A5 mutation on neuropathy grade and assist of ADL as a part of neurotoxicity.

Abstract
BACKGROUND AND OBJECTIVE Side effects of irinotecan treatment can be dose limiting and may impair quality of life. In this study, we investigated the correlation between single nucleotide polymorphisms (SNPs) in genes encoding enzymes involved in the irinotecan metabolism and transport, outside UGT1A1, and irinotecan-related toxicity. We focused on carboxylesterases, which are involved in formation of the active metabolite SN-38 and on drug transporters. METHODS Patients who provided written informed consent at the Erasmus Medical Center Cancer Institute to the Code Geno study (local protocol: MEC02-1002) or the IRI28-study (NTR-6612) were enrolled in the study and were genotyped for 15 SNPs in the genes CES1, CES2, SLCO1B1, ABCB1, ABCC2, and ABCG2. RESULTS From 299 evaluable patients, 86 patients (28.8%) developed severe irinotecan-related toxicity. A significantly higher risk of toxicity was seen in ABCG2 c.421C>A variant allele carriers (P = 0.030, OR 1.88, 95% CI 1.06-3.34). Higher age was associated with all grade diarrhea (P = 0.041, OR 1.03, 95% CI 1.00-1.06). In addition, CES1 c.1165-41C>T and CES1 n.95346T>C variant allele carriers had a lower risk of all-grade thrombocytopenia (P = 0.024, OR 0.42, 95% CI 0.20-0.90 and P = 0.018, OR 0.23, 95% CI 0.08-0.79, respectively). CONCLUSION Our study indicates that ABCG2 and CES1 SNPs might be used as predictive markers for irinotecan-induced toxicity.

Abstract
OBJECTIVE Vincristine is a mainstay treatment for paediatric cancers, particularly acute lymphoblastic leukemia (ALL), with common toxicity including vincristine-induced peripheral neuropathy (VIPN). The present study comprehensively assessed VIPN outcomes in patients receiving vincristine treatment for ALL. METHODS Children diagnosed with ALL commencing vincristine treatment were prospectively evaluated (baseline, post-induction, pre-reinduction, post-reinduction, follow-up). VIPN was examined clinically using the Balis sensory/motor scale, neurophysiologically using axonal excitability techniques and quality-of-life using Pediatric Quality of Life Inventory. RESULTS Thirty-one patients were recruited to this study (age = 6.8 ± 4.4; 61.3% female). Incidence of motor VIPN (motor Balis grade > 0) symptoms were higher than sensory VIPN (sensory Balis grade > 0) at post-induction (92.0% vs 36.0%) and post-reinduction (81.8% vs 22.7%) vincristine treatment. Neurophysiological assessment also demonstrated greater change in motor axonal excitability parameters compared to sensory parameters including changes in depolarising threshold electrotonus (P < 0.0125), superexcitability and subexcitability parameters (all P < 0.0125). Follow-up assessment demonstrated persisting VIPN symptoms with reduced quality-of-life scores compared to baseline. CONCLUSIONS Clinical and neurophysiological evaluation of VIPN suggests vincristine produces a motor-prominent sensorimotor neuropathy in children which persisted at follow-up. SIGNIFICANCE VIPN signs and symptoms develop early in the treatment course, in line with axonal excitability profiles. Early detection of significant nerve changes may support timely implementation of neuroprotection strategies.

Abstract
INTRODUCTION Vincristine is an integral component of treatment for children with cancer. Its main dose-limiting side effect is vincristine-induced peripheral neuropathy (VIPN). The VINCA trial was a randomized controlled trial that explored the effect of 1-hour infusion compared with push injection of vincristine on the development of VIPN in children with cancer. The short-term outcomes (median follow-up 9 months) showed that there was no difference in VIPN between the randomization groups. However, 1-hour infusion was less toxic in children who also received azoles. We now report the results of the final analyses (median follow-up 20 months), which includes treatment outcome as a secondary objective (follow-up 3 years). METHODS VIPN was measured 1-7 times per participant using the Common Terminology Criteria for Adverse Events (CTCAE) and the pediatric-modified total neuropathy score. Poisson mixed model and logistic generalized estimating equation analysis for repeated measures were performed. RESULTS Forty-five participants per randomization group were included. There was no significant effect of 1-hour infusion compared with push injection on VIPN. In participants receiving concurrent azoles, the total CTCAE score was significantly lower in the one-hour group (rate ratio 0.52, 95% confidence interval 0.33-0.80, p = 0.003). Four patients in the one-hour group and one patient in the push group relapsed. Two patients in the one-hour group died. CONCLUSION 1-hour infusion of vincristine is not protective against VIPN. However, in patients receiving concurrent azoles, 1-hour infusion may be less toxic. The difference in treatment outcome is most likely the result of differences in risk profile.

Abstract
PURPOSE The variability on irinotecan (IRI) pharmacokinetics and toxicity has been attributed mostly to genetic variations in the UGT1A1 gene, responsible for conjugation of the active metabolite SN-38. Also, CYP3A mediates the formation of inactive oxidative metabolites of IRI. The association between the occurrence of severe adverse events, pharmacokinetics parameters, and UGT1A1 and CYP3A4 predicted phenotypes was evaluated, as the evaluation of [SN-38]/IRI dose ratio as predictor of severe adverse events. METHODS Forty-one patients undergoing IRI therapy were enrolled in the study. Blood samples were collected 15 min after the end of drug the infusion, for IRI, SN-38, SN-38G, bilirubin concentrations measurements, and UGT1A1 and CYP3A genotype estimation. Data on adverse event was reported. RESULTS Fifteen patients (36.5%) developed grade 3/4 adverse events. A total of 9.8% (n = 4) of the patients had UGT1A1 reduced activity phenotype, and 48.7% (n = 20) had UGT1A1 and 63.4% (n = 26) CYP3A intermediary phenotypes. Severe neutropenia and diarrhea were more prevalent in patients with reduced UGT1A1 in comparison with functional metabolism (50% and 75% versus 0% and 13%, respectively). SN-38 levels and its concentrations adjusted by IRI dose were significantly correlated to toxicity (rs = 0.31 (p = 0.05) and rs = 0.425 (p < 0.01)). The [SN-38]/IRI dose ratio had a ROC curve of 0.823 (95% CI 0.69-0.956) to detect any severe adverse event and 0.833 (95% CI 0.694-0.973) to detect severe diarrhea. The cut-off of 0.075 ng mL-1 mg-1 had 100% sensitivity and 65.7% specificity to predict severe diarrhea. CONCLUSION Our data confirmed the relevance of the pre-emptive genotypic information of UGT1A1. The [SN-38]/IRI ratio, measured 15 min after the end of the IRI infusion, was a strong predictor of severe toxicity and could be applied to minimize the burden of patients after IRI administration.

Abstract
OBJECTIVES To study the characteristics of vincristine-induced peripheral neuropathy (VIPN) in children with acute lymphoblastic leukemia (ALL) and the factors influencing the development of VIPN. METHODS The children with ALL, aged 1-18 years, who were treated with CCCG-ALL2015 or CCCG-ALL2020 regimen in the Affiliated Hospital of Guizhou Medical University from January 2018 to February 2022 were enrolled as subjects. According to the influence of age on risk, the children were divided into 1-10 years group with 91 children and >10 years group with 29 children. VIPN was graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (5th edition), and the incidence rate, severity, and type of VIPN were compared between different groups. RESULTS A total of 120 children were enrolled in this study, among whom 56 (46.7%) developed VIPN. The >10 years group had a significantly higher incidence rate of VIPN than the 1-10 years group (69% vs 40%, P<0.05). Among the 56 children with VIPN, 12 (21%) had grade 3 VIPN or above, and 44 (79%) had grade 2 VIPN. There were 77 cases of autonomic nerve symptoms (59.7%), 42 cases of peripheral nerve injury (32.5%), and 10 cases of cranial nerve injury (7.8%). There were no significant differences in the severity and type of VIPN between the groups with different ages, sexes, degrees of risk, or treatment regimens (P>0.05). The results of binary logistic regression analysis showed that age is the influencing factor for the occurrence of VIPN (P>0.05). CONCLUSIONS There is a relatively high incidence rate of VIPN in children with ALL, with the highest incidence rate of autonomic nervous symptoms. The incidence of VIP in children over 10 years old is relatively high.

Abstract
Importance Taxane-based chemotherapy agents, such as docetaxel and paclitaxel, are used for treating a wide range of cancers. Although much has been published on adverse events related to taxanes, data on ocular outcomes with these very important drugs are scant. Objective To quantify the risk of 3 mutually exclusive ocular adverse events of epiphora, cystoid macular edema (CME), and optic neuropathy with taxane-based chemotherapy agents by undertaking a large pharmacoepidemiologic study. Design, Setting, and Participants This retrospective cohort study design used a private health-claims database from the US that captures health information of more than 150 million enrollees. The study team created a cohort of new users of women with cancer who were taking taxane-based chemotherapy (docetaxel or paclitaxel) and new users of tamoxifen as controls. Study members were observed to the first incidence of each of the 3 mutually exclusive outcomes. An analysis of taxane-only users was also undertaken. Exposure Tamoxifen (unexposed) and taxanes (ie, paclitaxel and docetaxel) as the exposed. Main Outcomes and Measures First diagnosis of (1) epiphora, (2) cystoid macular edema (CME), or (3) optic neuropathy ascertained using International Statistical Classification of Diseases and Related Health Problems, Ninth Revision or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision. Results Among the 18 219 users in the epiphora analysis and optic neuropathy analysis, there were 1824 taxane users (paclitaxel and docetaxel) (age, mean [SD], 62.1 [12.7] years) and 16 395 tamoxifen users (age, mean [SD], 54.6 [12.8] years), respectively. The crude hazard ratio (HR) for epiphora was 5.55 (95% CI, 2.99-10.29) and adjusted HR was 5.15 (95% CI, 2.79-9.54). For optic neuropathy, the crude HR was 4.43 (95% CI, 1.10-17.82) and the adjusted HR was 4.44 (95% CI, 1.04-18.87). Among the 18 433 users in the CME analysis, there were 1909 taxane users (paclitaxel and docetaxel) (age, mean [SD], 62.5 years) and 16 524 tamoxifen users (age, mean [SD], 54.6 years). The crude HR for CME comparing taxane users with tamoxifen users was 1.37 (95% CI, 0.72-2.60) and adjusted HR was 1.33 (95% CI, 0.70-2.53). The HRs for epiphora and CME in the taxane cohort during the time of exposure compared with the period prior to use of the drugs were 2.86 (95% CI, 1.11-7.39) and 2.27 (95% CI, 0.68-7.54), respectively. Conclusions and Relevance In a cohort of women who were using taxane chemotherapy agents, there was an association with elevated risk for epiphora, CME, and optic neuropathy. Ophthalmologists and oncologists should be aware of these adverse events in women with breast cancer who receive these drugs.

Abstract
Paclitaxel is a commonly used chemotherapeutic agent. To minimize the risk of hypersensitivity reactions (HSRs), which occur in approximately 16-42% of patients, premedication with dexamethasone, clemastine, and ranitidine was standard of care. As of October 2019, ranitidine is no longer available. We compared the risk of HSRs to paclitaxel with and without premedication with ranitidine, hypothesizing that the incidence of HSRs to paclitaxel will be similar. In this retrospective cohort study, all first-time paclitaxel users in the Groene Hart Hospital were included from January 2019 to August 2020. The primary outcome was the incidence of HSRs, using a Student's t-test. One-hundred and eight patients who were first-time users of paclitaxel in the Groene Hart Hospital met the inclusion criteria. Most patients were treated for breast or ovarian cancer, followed by lung cancer. Analysis of all 836 paclitaxel administrations was performed. Following 349 administrations with ranitidine as premedication, eight HSRs occurred (2.3%), while following 487 administrations without ranitidine, 12 HSRs occurred (2.5%), p-value of 0.87. An additional analysis on the occurrence of HSRs per patient was performed: 45 patients received premedication in the form of ranitidine, of which eight patients (17.8%) had a HSR. Sixty-three patients did not receive premedication in the form of ranitidine, of whom 10 (15.8%) had a HSR, p-value of .80. In conclusion, we found no difference in the incidence of HSRs during paclitaxel infusions between patients who received ranitidine as premedication versus those who did not.

Abstract
OBJECTIVES Nab-paclitaxel is a chemotherapeutic drug used to treat various solid malignant tumors. It was conceived with a solvent free formulation to overcome toxicity events and hypersensitivity reactions associated with paclitaxel. However, it still carries ocular adverse effects. The present review examines nab-paclitaxel related cystoid macular edema (CME) and the available therapeutic options. MATERIALS AND METHODS The literature was reviewed on nab-paclitaxel related CME on published articles through January 2021 using the keywords "nab-paclitaxel "and "cystoid macular edema". RESULTS Bilateral CME is found in patients in treatment with nab-paclitaxel and causes considerable visual acuity decline. In ophthalmology multimodal imaging has an integral role in the diagnostic work up of patients and shows characteristic findings in nab-paclitaxel related CME. The case of a patient with treatment for bilateral CME is presented and analyzed. CONCLUSIONS The preferred management strategy for nab-paclitaxel-related CME is drug cessation that leads to complete resolution of edema. When discontinuation of treatment is not possible due to the systemic conditions of patients, effective alternative therapeutic modalities are topical dorzolamide or steroidal treatment. Given the higher complication hazards of intravitreal therapy topical treatment should be preferred owing to comparable efficacy.

Abstract
A 61-year old male was referred to the Ophthalmology department because of decreased bilateral visual acuity. The patient had metastatic pancreatic adenocarcinoma and was being treated with gemcitabine+nab-paclitaxel. On examination, the patient presented best corrected visual acuities of 4/20 and 2/20 in the right and left eye, respectively. The optical coherence tomography revealed bilateral severe macular edema. Macular edema was considered secondary to nab-paclitaxel and the drug was discontinued. Three months after drug discontinuation, the patient presented best corrected visual acuities of 20/20 and 16/20 in the right and left eye, respectively, and normal fundoscopy. Macular edema is a very rare side effect of taxanes, and the etiopathology is still unknown. Edema is usually reversible upon discontinuation of the offending agent. Clinicians should be aware of this adverse effect of taxanes, and a high index of clinical suspicion is essential for diagnosis.

Bioactive chemical constituents, in vitro anti-proliferative activity and in vivo toxicity of the extract of Curcuma singularis Gagnep rhizomes. JOURNAL OF ETHNOPHARMACOLOGY 2022; 284:114803. [PMID: 34748866 DOI: 10.1016/j.jep.2021.114803] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/26/2021] [Revised: 11/02/2021] [Accepted: 11/03/2021] [Indexed: 06/13/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Curcuma singularis Gagnep is a Vietnamese medicinal plant which has been commonly used as a medicinal remedy in traditional and folk medicines for improving health as well as for treating some diseases, like rheumatoid arthritis, kidney failure. However, pharmacological effects, including anti-cancer activity and the safety of this plant has not been fully investigated. AIM OF THE STUDY This study aimed to investigate the in vitro anti-growth activity of an extract derived from Curcuma singularis rhizome extract (CSE) against cell lines as well as determine its phytochemical composition. The other goal of our study was to assess the safety of CSE in rats. MATERIALS AND METHODS The main constituents in the extract were identified and quantitatively analyzed. The in vitro cytotoxicity of CSE was evaluated in several cancer and normal cell lines. The apoptotic activity of CSE and the expression of the apoptosis-related genes were investigated in AGS cells to clarify the underlying molecular mechanisms. The in vivo toxicity of CSE was assessed via acute and subacute oral studies on Sprague-Dawley rats, respectively according to the guidelines 425 and 407 of the Organization for Economic Cooperation and Development (OECD). The drug-related toxicity signs, mortality, body and organ weights were recoreded during the experimental period. In addition, the selected hematological and biochemical parameters, and histological alterations were determined at the end of the subacute toxicity test. RESULTS Germacrone, ar-turmerone, and curcumol were three sesquiterpene components found in the extract. CSE showed cytotoxic effects in different cancer cells, but had minimal effects on normal cells. Apoptosis in AGS cells was caused by CSE in a concentration-dependent pattern through increase of Bax/Bcl-2 ratio, and release of cytochrome c, which leads to activation of caspase-3/-7, caspase-9, as well as cleavage of PARP. In the acute toxicity test, no signs of toxicity and no mortality were recorded in rats at both doses of 1000 and 5000 mg/kg. In the subacute toxicity study, CSE showed no drug-related adverse effects on water and food consumption, body and organ weights. CSE at a dose of 1000 mg/kg slightly increased WBC and platelet values in female rats, while it increased WBC values in male rats in all tested doses. The decrease of total cholesterol and triglyceride levels were found in female rats treated CSE at doses of 250 or 500 mg/kg. In addition, the increase of serum ALT and AST levels in rats treated at the dose of 1000 mg/kg were noted. No significant changes in histopathological structures of kidneys, spleen, heart and lungs, except liver tissue with minor modifications was found. CONCLUSIONS Our findings indicated that CSE exhibited in vitro anti-proliferative effects on AGS cells by mainly activating the caspase-dependent mitochondrial apoptotic pathway. CSE also showed in vivo toxicity signals at the dose of 1000 mg/kg with proven minor hepatic injuries, which should be avoided the high dose for prolonged use. Curcuma singularis rhizomes may be used as a chemotherapeutic agent for the treatment of gastric cancer with in vitro anti-cancer investigation and in vivo biological safety evaluation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Catharanthus roseus (L.) G. Don is a well known medicinal plant belonging to family Apocynaceae that have been traditionally used as medicine since ancient times. C. roseus is a well-recognized herbal medicine due to its anticancer bisindole alkaloids (vinblastine (111), vincristine (112) and vindesine (121)). In the Ayurvedic system of medicine, different parts of C. roseus are used in folklore herbal medicine for treatment of many types of cancer, diabetes, stomach disorders, kidney, liver and cardiovascular diseases. AIM OF THE STUDY The main idea behind this communication is to update comprehensively and analyze critically the traditional applications, phytochemistry, pharmacological activities, and toxicity of various extracts and isolated compounds from C. roseus. MATERIALS AND METHODS The presented data covers scientific works on C. roseus published across the world between 1967 and 2021 was searched from various international publishing houses using search engines as well as several traditional texts like Ayurveda and relevant books. Collected data from different sources was comprehensively summarized/analyzed for ethnomedicinal uses, phytochemistry, analytical chemistry, biological activities and toxicity studies of C. roseus. RESULTS AND DISCUSSION C. roseus has a wide range of applications in the traditional system of medicine especially in cancer and diabetes. During phytochemical investigation, total of 344 compounds including monoterpene indole alkaloids (MIAs) (110), bisindole alkaloids (35), flavonoids (34), phenolic acids (9) and volatile constituents (156) have been reported in the various extracts and fractions of different plant parts of C. roseus. The extracts and isolated compounds of C. roseus have to exhibit many pharmacological activities such as anticancer/cytotoxic, antidiabetic, antimicrobial, antioxidant, larvicidal and pupicidal. The comparative toxicity of extracts and bioactive compounds investigated in dose dependent manner. The investigation of toxicity showed that the both extracts and isolated compounds are safe to a certain limit beyond that they cause adverse effects. CONCLUSION This review is a comprehensive, critically analyzed summarization of sufficient baseline information of selected topics in one place undertaken till date on C. roseus for future works and drug discovery. The phytochemical investigation including biosynthetic pathways showed that the MIAs and bisindole alkaloids are major and characteristic class of compounds in this plant. The present data confirm that the extracts/fractions and their isolated alkaloids especially vinblastine (111) and vincristine (112) have a potent anticancer/cytotoxic and antidiabetic property and there is a need for further study with particular attention to the mechanisms of anticancer activity. In biosynthesis pathways of alkaloids especially bisindole alkaloids, some enzymes and rearrangement are unexposed therefore it is required to draw special attention. It also focuses on attracting the attention of scientific communities about the widespread biological activities of this species for its better utilization prospects in the near future.

Abstract
More than 10% of women diagnosed with breast cancer during reproductive age carry hereditary germline pathogenic variants in high-penetrance BRCA genes or in others genes involved in DNA repair mechanisms such as PALB2, BRIP or ATM. Anticancer treatments may have an additional negative impact on the ovarian reserve and subsequently on the fertility of young patients carrying such mutations. Recently, the combination of carboplatin and paclitaxel is being recommended to these BRCA-mutated patients as neoadjuvant therapy. However, the impact on the ovary is unknown. Here, we investigated their effect of on the ovarian reserve using mice carriers of BRCA1-interacting protein C-terminal helicase-1 (BRIP1) mutation that plays an important role in BRCA1-dependent DNA repair. Results revealed that the administration of carboplatin or paclitaxel did not affect the ovarian reserve although increased DNA double-strand breaks were observed with carboplatin alone. Co-administration of carboplatin and paclitaxel resulted in a significant reduction of the ovarian reserve leading to a lower IVF performance, and an activation of the PI3K-Pten pathway, irrespective of the genetic background. This study suggests that co-administration of carboplatin and paclitaxel induces cumulative ovarian damage and infertility but a heterozygote genetic predisposition for DNA damage related to BRCA1 gene function does not increase this risk.

Abstract
IMPORTANCE Multiple paclitaxel-based regimens are widely used in chemoradiation therapy against esophageal cancer, including regimens combining paclitaxel with fluorouracil, cisplatin, and carboplatin. However, which among these 3 regimens provides the best prognosis with minimum adverse events is still unknown. OBJECTIVE To compare the efficacy and adverse events of fluorouracil, cisplatin, and carboplatin in definitive chemoradiotherapy in patients with esophageal squamous cell carcinoma (ESCC). DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial of patients with ESCC was conducted in 11 treatment centers in China. Eligible patients were aged 18 to 75 years and had histologically confirmed ESCC stages IIa to IVa with no prior treatment, Eastern Cooperative Oncology Group performance status of 2 or lower, and adequate organ functions. The study was conducted between July 2015 and February 2018, and the cutoff date for data analysis was August 31, 2020. INTERVENTIONS Patients with locally advanced ESCC were randomly assigned (1:1:1) to groups combining paclitaxel treatment with fluorouracil, cisplatin, or carboplatin. Patients in the cisplatin group were treated with 2 cycles of concurrent chemoradiotherapy followed by 2 cycles of consolidation chemotherapy with monthly paclitaxel plus cisplatin. For the fluorouracil group, patients were administered 6 cycles of weekly paclitaxel plus fluorouracil in concurrent chemoradiotherapy followed by 2 cycles of monthly paclitaxel plus fluorouracil in consolidation chemotherapy. Patients in the carboplatin group were treated with 6 cycles of weekly paclitaxel plus carboplatin in concurrent chemoradiotherapy followed by 2 cycles of monthly paclitaxel plus carboplatin in consolidation chemotherapy. All patients received radiotherapy of 61.2 Gy delivered in 34 fractions. MAIN OUTCOMES AND MEASURES The primary end point was overall survival (OS). The secondary end points were progression-free survival and adverse events. RESULTS Overall, 321 patients (median [IQR] age, 64 years [59-69 years]; 248 [77.3%] men) with ESCC from 11 centers were randomized into fluorouracil, cisplatin, or carboplatin groups between July 2015 and February 2018. Over a median (IQR) follow-up time of surviving patients of 46.0 months (36.6-53.0 months), the 3-year OS rates were 57.2% in the fluorouracil group, 60.1% in the cisplatin group, and 56.5% in the carboplatin group, respectively (fluorouracil vs cisplatin: HR, 1.06; 95% CI, 0.71-1.60; P = .77; fluorouracil vs carboplatin: HR, 0.94; 95% CI, 0.63-1.40; P = .77). The cisplatin group had significantly higher incidences of acute grade 3 or 4 neutropenia (69 events [60.8%] vs 19 [17.8%] for fluorouracil and 37 [34.6%] carboplatin; P < .001), thrombocytopenia (14 events [13.1%] vs 4 [3.7%] for fluorouracil and 5 [4.7%] for carboplatin; P = .01), anemia (50 events above grade 2 [46.7%] vs 25 [23.4%] for fluorouracil and 37 [34.6%] for carboplatin; P = .35), fatigue (11 events [10.3%] vs 2 [1.9%] for fluorouracil and 1 [0.9%] carboplatin; P = .007), and vomiting (17 events above grade 2 [15.9%] vs 3 [2.8%] for fluorouracil and 5 [4.7%] for carboplatin; P < .001) than the other 2 groups. CONCLUSIONS AND RELEVANCE In this randomized clinical trial, paclitaxel plus fluorouracil did not show OS superiority over paclitaxel plus cisplatin or paclitaxel plus carboplatin regimens in definitive chemoradiation in patients with locally advanced ESCC. Higher rates of hematologic and gastrointestinal toxic effects were reported in the cisplatin group compared with those in the fluorouracil or carboplatin groups.

Abstract
Paclitaxel is a high-alert IV oncology medication that causes hypersensitivity reactions (HSRs) in 10%-40% of infusions, predominantly during the first or second infusion. Although paclitaxel has been a common medication in cancer treatment regimens for decades, the literature fails to address the safest approach for administration to minimize HSRs. Oncology teams may implement different methods of administration. To address safety concerns and inconsistent findings in the literature, an advanced oncology clinical nurse specialist initiated a team-based quality improvement project. This retrospective study included chart reviews to assess organizational outpatient practices and documentation for paclitaxel administration. Results from this project were the basis for reinstating a standard order set, which includes titration during the first and second paclitaxel infusions to maximize patient safety.

Abstract
CONTEXT Kang-ai injection (KAI) is an authorized herbal medicine used in cancer treatment. However, its clinical efficacy in hepatocellular carcinoma (HCC) has not been investigated thoroughly. OBJECTIVE To systematically evaluate the efficacy and safety of KAI in patients with HCC. MATERIALS AND METHODS The Web of Science, PubMed, Cochrane Library, EMBASE, CBM, CNKI, VIP and Wanfang databases were systematically searched (date range: inception to December 2020) using the key terms 'Kang-ai injection' and 'hepatocellular carcinoma'. The current analysis included controlled clinical trials that compared the efficacy and safety of the combination of KAI and conventional treatment (CT) with CT alone for HCC. The current study estimated the pooled risk ratio (RR) with 95% confidence intervals (CI). RESULTS Data pertaining to 35 trials with 2501 HCC patients were analysed. The results revealed that the combination of KAI and CT was associated with significantly superior objective response rate (RR = 1.57, 95% CI = 1.43-1.73), disease control rate (RR = 1.18, 95% CI = 1.10-1.26), and quality of life (RR = 2.40, 95% CI = 1.79-3.23), compared to CT alone. The administration of KAI significantly alleviated most of the adverse effects caused by CT, including nausea and vomiting, liver damage, peripheral neurotoxicity, fever, abdominal pain, alopecia, increased bilirubin levels, leukopoenia, and reduction in haemoglobin levels (p < 0.05, for all). CONCLUSIONS The current meta-analysis indicates that a combination of CT and KAI could be more effective in improving the clinical efficacy of the treatment of HCC, compared to CT alone.

Abstract
CONTEXT Bupleuri Radix, the dried root of Bupleurum chinense DC and Bupleurum scorzonerifolium Willd (Apiaceae), is an important medicinal herb widely used to treat cancers for hundreds of years in Asian countries. As the most antitumour component but also the main toxic component in Bupleuri Radix, saikosaponin D (SSD) has attracted extensive attention. However, no summary studies have been reported on the antitumour effects, toxicity and pharmacokinetics of this potential natural anticancer substance. OBJECTIVE To analyse and summarise the existing findings regarding to the antitumour effects, toxicity and pharmacokinetics of SSD. MATERIALS AND METHODS We collected relevant information published before April 2021 by conducting a search of literature available in various online databases including PubMed, Science Direct, CNKI, Wanfang database and the Chinese Biological Medicine Database. Bupleurum, Bupleuri Radix, saikosaponin, saikosaponin D, tumour, toxicity, and pharmacokinetics were used as the keywords. RESULTS The antitumour effects of SSD were multi-targeted and can be realised through various mechanisms, including inhibition of proliferation, invasion, metastasis and angiogenesis, as well as induction of cell apoptosis, autophagy, and differentiation. The toxicological effects of SSD mainly included hepatotoxicity, neurotoxicity, haemolysis and cardiotoxicity. Pharmacokinetic studies demonstrated that SSD had the potential to alter the pharmacokinetics of some drugs for its influence on CYPs and P-gp, and the oral bioavailability and actual pharmacodynamic substances in vivo of SSD are still controversial. CONCLUSIONS SSD is a potentially effective and relatively safe natural antitumour substance, but more research is needed, especially in vivo antitumour effects and pharmacokinetics of the compound.

Abstract
BACKGROUND In the global phase 3 RAINBOW study, ramucirumab plus paclitaxel significantly improved overall survival compared with placebo plus paclitaxel in patients with advanced gastric or gastro-oesophageal junction (GEJ) adenocarcinoma. RAINBOW-Asia, a bridging study with similar design to RAINBOW, aimed to evaluate the efficacy and safety of ramucirumab plus paclitaxel for advanced gastric or GEJ adenocarcinoma in Asian, predominantly Chinese, patients. METHODS RAINBOW-Asia was a randomised, double-blind, placebo-controlled, phase 3 trial done at 32 centres in China, Malaysia, the Philippines, and Thailand. Adult patients (≥18 years) with metastatic or locally advanced, unresectable gastric or GEJ adenocarcinoma who previously received fluoropyrimidine-platinum-based chemotherapy were randomly assigned with a centralised interactive web response system in a 2:1 ratio to receive ramucirumab 8 mg/kg or placebo intravenously on days 1 and 15 plus paclitaxel 80 mg/m2 intravenously on days 1, 8, and 15 of every 28-day cycle. Randomisation was stratified by Eastern Cooperative Oncology Group performance status and presence of peritoneal metastases. The co-primary endpoints were progression-free survival and overall survival. Efficacy analyses were done in the intention-to-treat population, and safety analysis included patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, NCT02898077, and has been completed. FINDINGS Between March 2, 2017, and June 30, 2020, 440 patients were randomly assigned to receive ramucirumab plus paclitaxel (n=294) or placebo plus paclitaxel (n=146). Median progression-free survival was 4·14 months (95% CI 3·71-4·30) in the ramucirumab plus paclitaxel group compared with 3·15 months (2·83-4·14) in the placebo plus paclitaxel group (hazard ratio [HR] 0·765, 95% CI 0·613-0·955, p=0·0184). Median overall survival was 8·71 months (95% CI 7·98-9·49) in the ramucirumab plus paclitaxel group and 7·92 months (6·31-9·10) in the placebo plus paclitaxel group (HR 0·963, 95% CI 0·771-1·203, p=0·7426). The most common grade 3 or worse treatment-emergent adverse events were decreased neutrophil count (159 [54%] of 293 patients in the ramucirumab plus paclitaxel group vs 56 [39%] of 145 in the placebo plus paclitaxel group), decreased white blood cell count (127 [43%] vs 42 [29%]), anaemia (46 [16%] vs 24 [17%]), hypertension (21 [7%] vs nine [6%]), and febrile neutropenia (18 [6%] vs one [<1%]). INTERPRETATION These findings, along with the results from RAINBOW, support the use of ramucirumab plus paclitaxel as second-line therapy in a predominantly Chinese population with advanced gastric or GEJ adenocarcinoma.

[PMID: 34775645 PMCID: PMC9299499 DOI: 10.1002/em.22467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 11/05/2021] [Accepted: 11/12/2021] [Indexed: 06/13/2023]
Abstract
We present a hypothetical case study to examine the use of a next-generation framework developed by the Genetic Toxicology Technical Committee of the Health and Environmental Sciences Institute for assessing the potential risk of genetic damage from a pharmaceutical perspective. We used etoposide, a genotoxic carcinogen, as a representative pharmaceutical for the purposes of this case study. Using the framework as guidance, we formulated a hypothetical scenario for the use of etoposide to illustrate the application of the framework to pharmaceuticals. We collected available data on etoposide considered relevant for assessment of genetic toxicity risk. From the data collected, we conducted a quantitative analysis to estimate margins of exposure (MOEs) to characterize the risk of genetic damage that could be used for decision-making regarding the predefined hypothetical use. We found the framework useful for guiding the selection of appropriate tests and selecting relevant endpoints that reflected the potential for genetic damage in patients. The risk characterization, presented as MOEs, allows decision makers to discern how much benefit is critical to balance any adverse effect(s) that may be induced by the pharmaceutical. Interestingly, pharmaceutical development already incorporates several aspects of the framework per regulations and health authority expectations. Moreover, we observed that quality dose response data can be obtained with carefully planned but routinely conducted genetic toxicity testing. This case study demonstrates the utility of the next-generation framework to quantitatively model human risk based on genetic damage, as applicable to pharmaceuticals.

Paclitaxel: Application in Modern Oncology and Nanomedicine-Based Cancer Therapy. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:3687700.

Abstract
Paclitaxel is a broad-spectrum anticancer compound, which was derived mainly from a medicinal plant, in particular, from the bark of the yew tree Taxus brevifolia Nutt. It is a representative of a class of diterpene taxanes, which are nowadays used as the most common chemotherapeutic agent against many forms of cancer. It possesses scientifically proven anticancer activity against, e.g., ovarian, lung, and breast cancers. The application of this compound is difficult because of limited solubility, recrystalization upon dilution, and cosolvent-induced toxicity. In these cases, nanotechnology and nanoparticles provide certain advantages such as increased drug half-life, lowered toxicity, and specific and selective delivery over free drugs. Nanodrugs possess the capability to buildup in the tissue which might be linked to enhanced permeability and retention as well as enhanced antitumour influence possessing minimal toxicity in normal tissues. This article presents information about paclitaxel, its chemical structure, formulations, mechanism of action, and toxicity. Attention is drawn on nanotechnology, the usefulness of nanoparticles containing paclitaxel, its opportunities, and also future perspective. This review article is aimed at summarizing the current state of continuous pharmaceutical development and employment of nanotechnology in the enhancement of the pharmacokinetic and pharmacodynamic features of paclitaxel as a chemotherapeutic agent.

Abstract
Vincristine, a key agent in the treatment of many pediatric malignancies, causes sensory, motor and autonomic neuropathy. We report the clinical courses of 5 patients who required cessation of vincristine after developing severe neurotoxicity during treatment for acute lymphoblastic leukemia. All 5 patients lost the ability to ambulate and 3 had additional severe neurotoxic side effects including vision loss and vocal cord dysfunction. Although prior literature reports poor outcomes for children in whom vincristine was discontinued during acute lymphoblastic leukemia therapy, all 5 patients described here achieved and have maintained complete continuous remission.
