RESUMO

BACKGROUND: We previously reported the results of a prospective study of chemotherapy-induced nausea and vomiting (CINV) in a cohort of patients who received carboplatin-based chemotherapy and were selected from a nationwide registry of those scheduled for moderately (MEC) or highly emetogenic chemotherapy (HEC) by the CINV Study Group of Japan. Of 1,910 previously registered patients (HEC: 1,195; MEC: 715), 400 patients received carboplatin-based chemotherapy. The frequency of CINV was determined, and the risk factors for CINV were assessed. MATERIALS AND METHODS: CINV data were collected from 7-day diaries. Risk factors for CINV were identified using logistic regression models. RESULTS: Of 400 patients scheduled for carboplatin-based chemotherapy, 267 patients received two antiemetics (5-hydroxytryptamine-3 receptor antagonist [5-HT3 RA] and dexamethasone [DEX]), 118 patients received three antiemetics (5-HT3 RA, DEX, and neurokinin-1 receptor antagonist [NK1 RA]), and 15 were nonadherent to the treatment. In these patients, the CINV overall, acute, and delayed phase rates of complete response (CR), defined as no vomiting with no rescue medication, were 67.0%, 98.2%, and 67.5%, respectively. The rates of no nausea were 55.6%, 94.0%, and 56.1%, respectively, and those of no vomiting were 81.3%, 99.0%, and 81.8%, respectively. Older age was associated with a decreased non-CR, whereas female sex, history of pregnancy-related emesis, and dual antiemetic therapy were associated with an increased non-CR during the overall period. CONCLUSION: In a clinical practice setting, in patients who received carboplatin-based chemotherapy, adherence is quite high and appropriate antiemetic prophylaxis requires a triple antiemetic regimen including NK1 RA. IMPLICATIONS FOR PRACTICE: For patients receiving carboplatin-based chemotherapy, triple antiemetic therapy with 5-hydroxytryptamine-3 receptor antagonist, dexamethasone, and neurokinin-1 receptor antagonist should be given prophylactically regardless of risk factor status.

RESUMO

BACKGROUND/AIM: To clarify whether renal dysfunction affects the incidence of adverse events associated with oxaliplatin, the present study was designed to investigate the relationship between creatinine clearance (Ccr) and the incidence of oxaliplatin-related adverse events. PATIENTS AND METHODS: A total of 287 CRC patients who received the first cycle of oxaliplatin-based chemotherapy were eligible. Adverse events, including nausea, vomiting, neutropenia and thrombocytopenia, were graded, and the relationship between Ccr and the incidence of adverse events was examined using multivariable logistic regression analysis. RESULTS: A multivariable analysis indicated that the incidence of grade ≥2 nausea increased, while the incidence of other adverse events tended to be higher, as the Ccr decreased. Particularly, renal dysfunction (Ccr <60 ml/min) was a significant risk factor for grade ≥2 nausea (p=0.042). CONCLUSION: Care should be taken to avoid adverse events associated with oxaliplatin in patients with renal dysfunction.

RESUMO

PURPOSE: The aim of this study was to investigate the efficacy and safety of prophylactic administration of 5 mg olanzapine (OLZ) combined with neurokinin 1 receptor antagonist (NK1RA), 5-hydroxytryptamine type-3 receptor antagonist (5-HT3RA), and dexamethasone (DEX) to prevent nausea and vomiting in carboplatin (CBDCA) combination therapy for patients with gynecological cancer. METHODS: We conducted a single-arm, multi-institution, phase II study. Gynecological cancer patients scheduled to receive AUC ≥4 mg/mL/min CBDCA were enrolled. All patients received 5 mg OLZ (once daily after supper on days 1-4) combined with NK1RA, 5-HT3RA, and DEX. The primary end point was complete response (CR; no emesis and rescue therapy) during overall phase (120 h after the start of carboplatin administration). RESULTS: Between May 2018 and June 2019, 60 patients were enrolled from 3 institutions in Japan. A total of 57 patients who met the criteria were included in the efficacy and safety analysis. The CR rate for the overall phase was 78.9%. Acute (0-24 h) and delayed phases (24-120 h) were 96.5% and 80.7%, respectively. Somnolence was observed in 73.7% patients. However, somnolence of grade 2 or higher was observed in only 3.5% of cases. There were no grade 3 or 4 toxicities associated with OLZ. CONCLUSIONS: Preventive use of OLZ combined with standard triplet therapy had promising activity with manageable safety, suggesting that this combination could be an effective standard treatment option for patients with AUC ≥4 mg/mL/min CBDCA combination therapy.

RESUMO

BACKGROUND: The increasing cost of anticancer drugs is now being recognised as a global problem, and measures against drug wastage are among the most important cost containment strategies for anticancer drugs. OBJECTIVE: When blood examination results or changes to a patient's condition necessitate dose reduction or discontinuation of anticancer drugs after their preparation, the compounded anticancer drugs are discarded. To reduce anticancer drug wastage after preparation, we developed a protocol that set the eligibility, start of treatment, dose reduction and discontinuation criteria for injectable anticancer drugs and assessed the effect of pharmacists' checks of these criteria based on the present protocol prior to preparation of injectable anticancer drugs. METHOD: Observations before and after introduction of the protocol were conducted at Gifu University Hospital. We recorded the number, type and cost of anticancer drugs discarded after preparation and the reason for discarding these drugs in our dedicated database. RESULTS: Checking the criteria for anticancer drug administration before preparation significantly reduced the rate at which anticancer drugs within a chemotherapy cycle were discarded after preparation compared with that prior to the protocol's introduction (0.367% [18/4909] vs 0.032% [2/6248], P < .001). Additionally, the total cost of anticancer drugs discarded after preparation was reduced from JPY 2 041 786 (USD 18 562) to JPY 398 414 (USD 3622). CONCLUSION: Pharmacists' checks of the eligibility, start of treatment, dose reduction and discontinuation criteria for anticancer drugs based on the present protocol prior to preparation of injectable anticancer drugs was useful for reducing drug wastage after preparation.

RESUMO

OBJECTIVE: TAS-102 is effective for treating patients with metastatic colorectal cancer (mCRC). This study determined whether combining bevacizumab (Bmab) with TAS-102 improves clinical outcomes in refractory mCRC. PATIENTS AND METHODS: We retrospectively analyzed data from Japanese patients with refractory mCRC who received TAS-102 (35 mg/m2, twice a day) with (T-B group) or without Bmab (TAS-102 monotherapy; T group) between July 2014 and December 2018. The primary endpoint was median overall survival (OS), and secondary endpoints were median time to treatment failure, overall response rate, and the incidence of adverse events. Clinical outcomes were compared using propensity score matched analysis. RESULTS: Data from 57 patients were analyzed (T-B group: 21 patients, T group: 36 patients). Median OS was significantly longer in the T-B group than the T group (14.4 months vs. 4.5 months, p < .001). Cox proportional hazard analysis showed that combination therapy with Bmab was significantly correlated with OS. Propensity score matched analysis confirmed that the median OS was significantly longer in the T-B group than the T group (14.4 months vs. 6.1 months, p = .006) and that there was a significant correlation between Bmab and OS. The incidence of hypertension (grade ≥2) as an adverse event was significantly higher in the T-B group than the T group (23.8% vs. 0.0%, p = .005), whereas other adverse events were comparable between the two groups. CONCLUSION: Treatment with Bmab in combination with TAS-102 is significantly associated with improved clinical outcomes in patients with mCRC refractory to standard therapies. IMPLICATIONS FOR PRACTICE: Combining bevacizumab (Bmab) with TAS-102 significantly improved overall survival and several prognostic indicators in patients with metastatic colorectal cancer (mCRC) refractory to standard therapies, with manageable toxicities. Treatment with Bmab in combination with TAS-102 is significantly associated with improved clinical outcomes in patients with mCRC.

RESUMO

BACKGROUND/AIM: Sunitinib is used for the treatment of metastatic renal cell carcinoma (mRCC). Asian patients, including Japanese, tend not to tolerate long-term sunitinib therapy of 50 mg p.o. once daily for 4 weeks, followed by 2 week off treatment due to severe adverse events at this dosage level. The aim of this retrospective study was to investigate the optimal dose of sunitinib for long-term continuation in Asian patients with mRCC. PATIENTS AND METHODS: The study cases were 50 patients with mRCC who were treated with sunitinib between June 2008 and December 2017. Risk analysis for "unacceptable" adverse events (depending on the physician, ranging from grade 2 to ≥ grade 3) leading to discontinuation of sunitinib was determined by time-dependent Cox proportional hazard regression analysis. RESULTS: A total of 54 unacceptable adverse events leading to discontinuation occurred. Multivariable analysis indicated that a sunitinib dose of ≤ 37.5 mg/day significantly reduced the risk of discontinuation due to adverse events in comparison with 50 mg/day [hazard ratio (HR) 0.08, 95% confidence interval (CI) 0.03-0.21, p < 0.001). The progression-free survival (PFS) with a sunitinib dose ≤ 37.5 mg/day was longer than that associated with a dose of 50 mg/day, albeit not to a statistically significant degree (120 days for ≤ 37.5 mg/day vs 41 days for 50 mg/day, HR 0.39, 95% CI 0.10-1.44, p = 0.157). CONCLUSION: Our findings suggest that the optimal dose of sunitinib for Asian, including Japanese, patients with mRCC is ≤ 37.5 mg/day.

RESUMO

OBJECTIVES: Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) represent the first-line treatment for patients with advanced EGFR mutation-positive non-small-cell lung cancer. Afatinib is a second-generation EGFR-TKI with excellent therapeutic effects. However, severe diarrhea and skin disorders are observed at high frequencies, often leading to treatment interruption because of low quality of life (QOL). The relationship between individual variations and the onset of these side effects remains to be elucidated. This study aimed to reveal the association among these side effects, pharmacokinetics, and related genetic polymorphisms. MATERIALS AND METHODS: In total, 33 patients were recruited between July 2014 and June 2017. Afatinib plasma concentrations were measured at day 9 when the concentrations reached a steady state (early phase) and when the prescription dose was stable for more than 1 month (stable phase). We analyzed single nucleotide polymorphisms in the genes ATP-binding cassette sub-family B member 1 (ABCB1), ABCG2, and flavin-containing monooxygenase 3. RESULTS: The incidences of both diarrhea and acneiform eruption were greater than 80%. Afatinib plasma concentration and the severity of diarrhea in the early phase were correlated. Pharmacokinetics-related genetic polymorphisms influenced the severity of diarrhea. Particularly, the afatinib plasma concentration was higher and diarrhea was more severe in patients carrying the A allele of ABCG2 C421A. Onset of side effects, genetic polymorphisms, and diarrhea in the maintenance phase or acneiform eruption in the early or maintenance phases were not correlated. The severity of diarrhea is influenced by drug plasma concentrations in the early phase and genetic polymorphisms related to afatinib pharmacokinetics. CONCLUSION: Particular genetic polymorphisms can be screened before afatinib administration and the dose adapted to individual patients can be controlled, leading to reduced side effects, improved QOL, and better patient compliance to maintain the therapeutic effects.

RESUMO

INTRODUCTION: Adding neurokinin-1 receptor antagonist (NK1RA) to 5-hydroxytryptamine-3 receptor antagonist and dexamethasone (DEX) improved carboplatin (CBDCA)-induced chemotherapy-induced nausea and vomiting (CINV) in patients with thoracic cancer. NK1RAs with high-drug cost are raising medical expenses. Olanzapine (OLZ) is less expensive and can be expected to have an excellent effect on CINV. This phase II trial aimed at evaluating the efficacy and safety of 5 mg OLZ plus granisetron (GRN) and DEX in CBDCA combination therapy with area under curve (AUC) ≥5 mg/mL/min for the prevention of nausea and vomiting in patients with thoracic cancer. METHODS AND ANALYSIS: This is an open-label, single-arm, multicentre, phase II trial. Patients who receive CBDCA-based therapies (AUC ≥5) and have never been administered moderate to high emetogenic chemotherapy will be enrolled. All patients will receive a combination of GRN, DEX and OLZ. The primary endpoint is complete response (CR) rate, defined as the absence of emetic episodes and no use of rescue medication for 120 hours after the initiation of CBDCA. Forty-eight patients are required based on our hypothesis that this regimen can improve CR rate from 65% (null hypothesis) to 80% (alternative hypothesis) with a one-sided type I error of 0.1 and a power of 0.8. We set the target sample size at 50 considering dropouts. ETHICS AND DISSEMINATION: The study protocol was approved by the institutional review board at each of the participating centres. Data will be presented at international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: UMIN000031267.

RESUMO

INTRODUCTION: Carboplatin (CBDCA) administered at a dosage of 4 mg/mL/min or more area under the blood concentration-time curve (AUC) is considered to be ranked as the highest chemotherapy-induced nausea and vomiting (CINV) risk of the moderately emetogenic chemotherapy agents. The complete response (CR) rate for preventing overall CINV, defined as no emetic episodes and no use of rescue medication, for standard triplet antiemetic therapy (5-HT3RA, 5-hydroxytryptamine-3 receptor antagonist; NK1RA, neurokinin-1 receptor antagonist; DEX, dexamethasone) was approximately 60% in gynaecological cancer patients receiving CBDCA-based therapy. Further improvement in antiemetic treatment is needed to optimise care. This trial is to evaluate the efficacy and safety of using 5 mg olanzapine (OLZ) plus standard triplet antiemetic therapy for CINV after AUC ≥4 mg/mL/min CBDCA combination therapy in gynaecological cancer patients. METHODS AND ANALYSIS: This trial is an open-label, single-arm, multicentre phase II trial. Patients who receive CBDCA (AUC ≥4)-based therapy and have never been administered moderate to high emetogenic chemotherapy will be enrolled. All patients will receive OLZ (5 mg oral administration on days 1-4, after supper) in combination with 5-HT3RA, NK1RA and DEX. The primary endpoint is the CR rate during the overall period (0-120 hours). Testing the hypothesis that this regimen can improve CR rate from 60% (null hypothesis) to 75% (alternative hypothesis) with a one-sided type I error of 0.1 and power of 0.8 will require 53 patients. Considering the dropout rate, the target sample size is set at 60. ETHICS AND DISSEMINATION: The study protocol was approved by the institutional review board at each of the participating centres. Data will be presented at international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: UMIN000031646.

RESUMO

BACKGROUND/AIM: Cholinergic syndrome frequently occurs within the first 24 h after irinotecan injection. We evaluated the prophylactic effect of scopolamine butylbromide on irinotecan-related cholinergic syndrome. PATIENTS AND METHODS: Fifty-nine patients who received irinotecan-based regimens at our outpatient chemotherapy clinic between April 2013 and May 2014 were enrolled. Patients who developed irinotecan-related cholinergic syndrome were prophylactically administered scopolamine butylbromide at the next scheduled treatment. Risk factors for irinotecan-related cholinergic syndrome were determined using logistic regression analysis. RESULTS: Irinotecan-related cholinergic syndrome occurred in 50.8% of patients. Scopolamine butylbromide administration significantly reduced the incidence to 3.4% (P < 0.01). The irinotecan dose (≥ 150 mg/m2) was the only risk factor associated with irinotecan-related cholinergic syndrome. The incidence of cholinergic syndrome in patients with this risk factor was 75%. CONCLUSION: Scopolamine butylbromide was effective in preventing irinotecan-related cholinergic syndrome. It is recommended for patients receiving ≥ 150 mg/m2 irinotecan who may develop cholinergic syndrome at high frequency.

RESUMO

BACKGROUND/AIM: Dysgeusia is one of the adverse events frequently affecting patients undergoing cancer chemotherapy. Dysgeusia-induced anorexia could decrease patient's quality of life. The present study was designed to determine whether the zinc-containing compound polaprezinc improves chemotherapy-induced dysgeusia. PATIENTS AND METHODS: The incidence of grade 2 dysgeusia was assessed in 634 patients receiving cancer chemotherapy in outpatient settings during January 2013 and June 2017. Polaprezinc was administered to patients showing grade 2 dysgeusia and the effect was compared with that in patients subjected to follow-up observation. RESULTS: Grade 2 dysgeusia appeared in 80 patients (12.6%), in whom pancreatic cancer and treatment with fluoropyrimidines were significant risks for dysgeusia. Polaprezinc, when administered to patients with grade 2 dysgeusia, significantly shortened the duration of dysgeusia compared with that in the follow-up observation group. Subgroup analysis indicated that polaprezinc was less effective in patients with pancreatic cancer, those receiving gemcitabine, or those whose age was 65 year-old and over. CONCLUSION: Chemotherapy-induced dysgeusia occurred with high frequency in patients with pancreatic cancer or in those receiving fluoropyrimidines. Polaprezinc was highly effective in improving the symptom of dysgeusia, except for patients with pancreatic cancer, those receiving gemcitabine and the elderly.

RESUMO

BACKGROUND: Cisplatin is commonly used for esophageal and gastric cancer, but has a high emetic risk. Although the control of vomiting is favorable, nausea is still poorly controlled in patients receiving cisplatin-based regimens. The present study was designed to determine the risks for cisplatin-induced nausea. The effect of olanzapine, an antipsychotic drug, as an antiemetic for patients with risk of poor control of nausea was subsequently examined. PATIENTS AND METHODS: The prevalence of antiemetic medication and the control of nausea and vomiting were retrospectively examined in patients with esophageal or gastric cancer receiving the first cycle of cisplatin-based chemotherapy. Risks for nausea were analyzed by multivariate logistic regression analysis, in which threshold for age and cisplatin dose wer assessed by receiver operating characteristic curve analysis. RESULTS: A total of 186 patients received cisplatin-based regimens during January 2011 and December 2016. Guideline-consistent antiemetic medication was administered to all patients. Although the rate of no vomiting was high (93%), the rate of non-significant (grade 2 or more) nausea was insufficient (64%) during the overall period. Risk analysis showed that cisplatin dose of 50 mg/m2 or more and female gender were significant risks for nausea. Addition of olanzapine, but not of prochlorperazine, to the standard antiemetic medication was effective in suppressing nausea in patients who experienced nausea in the first cycle. CONCLUSION: Being female and cisplatin doses at 50 mg/m2 or more were demonstrated to increase risk for nausea. Addition of olanzapine to the standard medication was effective in preventing nausea in high-risk patients with esophageal and gastric cancer.

RESUMO

BACKGROUND: Carboplatin (CBDCA) is known to exhibit a high emetic risk among moderate-emetic risk anticancer drugs, and the dose of CBDCA varies in different therapies. In concurrent chemoradiotherapy (CCRT) for non-small cell lung cancer (NSCLC), the weekly administration of CBDCA (area under the curve (AUC) 2 mg/ml/min) and paclitaxel (PTX: 40 mg/m2) is frequently applied as standard therapy. However, the optimal antiemetic measures in the use of such low-dose CBDCA remain unclear. In this study, we retrospectively assessed the antiemetic effect of a single-dose of a first-generation 5-hydroxytryptamine-3 receptor antagonist (5-HT3RA) and dexamethasone in the weekly CBDCA+PTX therapy in CCRT. PATIENTS AND METHODS: The subjects were patients with NSCLC who were administered weekly CBDCA+PTX therapy in CCRT between January 2011 and December 2016 at our Department. As an antiemetic measure, a first-generation 5-HT3RA, azasetron (10 mg, orally) or granisetron (3 mg, intravenously), and dexamethasone (9.9 mg, intravenously) were administered on day 1. The patients were evaluated for the following efficacy end-points for the first cycle: Complete response (CR; defined as no vomiting or retching episodes with no rescue medication) in the acute phase (0-24 hours), delayed phase (>24-120 hours), and overall phase (0-120 hours). Other efficacy endpoints evaluated were no vomiting or retching, and no nausea in all phases. RESULTS: The subjects we assessed in this study were 46 patients who were administered weekly CBDCA+PTX therapy in CCRT. For the overall, acute, and delayed phases, the complete response rates were 89.1%, 100%, and 89.1%, respectively. The rate of no nausea in the overall, acute, and delayed phases was 78.3%, 100%, and 78.3%, respectively. The rate of no vomiting in the overall, acute, and delayed phases was 95.7%, 100%, and 95.7%, respectively. CONCLUSION: A single dose of a first-generation 5-HT3RA and dexamethasone had a favorable suppressive effect on nausea and vomiting in weekly CBDCA+PTX therapy for NSCLC.

RESUMO

Leptomeningeal metastases occur in 1% of patients with non-small-cell lung cancer. There have been several reports on the treatment of leptomeningeal metastases with afatinib. Our patient was a 41-year-old woman who had never smoked and was diagnosed with stage IV adenocarcinoma of the lung with an epidermal growth factor receptor (EGFR) mutation. She was treated with afatinib for the recurrence of leptomeningeal metastases. After the treatment with afatinib was initiated, the neurological symptoms dramatically regressed, and she achieved progression-free survival for 7 months. The concentration of afatinib in the cerebrospinal fluid (CSF) ranged from 0.05 to 0.14 ng/mL, and the penetration rate of afatinib from the plasma to the CSF ranged from 0.28 to 0.40%. This concentration might be sufficient to achieve a clinical effect for leptomeningeal carcinomatosis. Therefore, afatinib administered at the usual doses may be an effective treatment for leptomeningeal carcinomatosis of EGFR-mutated or EGFR-tyrosine kinase inhibitor-sensitive lung adenocarcinoma.

RESUMO

The treatment for patients with lung cancer undergoing hemodialysis, who are frequently elderly and have poor performance status, becomes a more important subject. However, the feasibility of afatinib in patients with chronic renal failure undergoing hemodialysis has not, so far, been reported. Here, afatinib was administered to three patients with NSCLC harboring EGFR mutation and chronic renal failure undergoing hemodialysis. Pharmacokinetic (PK) data of afatinib supported the safety of afatinib treatment. After receiving their written informed consent from all patients, they were administered 30 mg afatinib daily with HD three times a week. We performed PK analyses of afatinib on days 1, 2, 10, and 11 after initial administration of afatinib. All three patients exhibited a partial response without any serious adverse events during the administration of afatinib. These PK data were similar to those of patients with normal organ function, which were previously reported. Our findings may be particularly useful given the current opportunity to use afatinib as a first-line treatment for EGFR-mutated NSCLC patients, providing an additional option for patients with impaired renal function.

RESUMO

BACKGROUND: Chemotherapy with moderate emetic risk (MEC), including irinotecan-based and oxaliplatin-based chemotherapy regimens, are predominantly used for colorectal cancer chemotherapy. Chemotherapy-induced nausea and vomiting (CINV) remain unsatisfactorily controlled. PATIENTS AND METHODS: The rates of prevalence of antiemetic medication and the control of CINV were investigated from medical records in patients with colorectal cancer who received the first cycle of irinotecan-based or oxaliplatin-based regimens. Risks for CINV were determined by multivariate logistic regression analysis. RESULTS: A total of 179 patients received the first cycle of MEC regimens and the number of overall cycles was 2,176 during the study period from January 2013 to December 2015. Guideline-consistent antiemetic medication was performed in most cases. The rate of no-CINV was nearly 90% during the overall period. Female sex and age under 50 years were significant risks for CINV. Comparison considering only the group aged 50 years or more indicated that the control of CINV was significantly worse in irinotecan-based regimens than in the oxaliplatin-based regimens. CONCLUSION: Female sex and age younger than 50 years were significant risks for CINV in patients receiving MEC for colorectal cancer. Moreover, the control of CINV was less sufficient for irinotecan-based than for oxaliplatin-based regimens.

RESUMO

BACKGROUND: Different antiemetic medications with or without aprepitant are recommended for moderately emetic-risk chemotherapy (MEC) depending on the emetic potential of chemotherapy agents, although the criterion for the use of aprepitant is still unclear. The present study was designed to compare the control of chemotherapy-induced nausea and vomiting (CINV) among several MEC regimens used in the outpatient chemotherapy setting. MATERIALS AND METHODS: A single center prospective observational study was carried out in 326 patients who received 2,061 chemotherapy cycles from January 2013 to December 2014. Antiemetic medication consisting of two-drug combination of granisetron (day 1) and dexamethasone (days 1-3) was carried out in 87.6% of patients receiving the first chemotherapy cycle. The checklist for CINV was provided to all patients, and the control of CINV was evaluated on the next visit based on the checklist. Complete inhibition of nausea and vomiting during acute and delayed periods were compared among MEC regimens. RESULTS: Two hundred and one patients received the first cycle of chemotherapy, in which the rates of complete inhibition of nausea and vomiting were 87.6% and 95.5%, respectively, during acute period, and 68.2% and 92.0%, respectively, during delayed period. There were no significant differences in the control of CINV among oxaliplatin, carboplatin and irinotecan, except for the cyclophosphamide-base regimen. CONCLUSIONS: Two-drug antiemetic medication of 5-HT3 receptor antagonist and dexamethasone was sufficiently effective for prevention of CINV in most MEC regimens.

RESUMO

PURPOSE: Although anti-EGFR monoclonal antibodies, including cetuximab and panitumumab, are highly effective in KRAS wild-type advanced colorectal cancer, these drugs frequently cause several adverse events. These events include hypomagnesemia and acneiform rash, which may lead to the dose reduction or discontinuation of therapy. In the present study, we retrospectively investigated the incidence of hypomagnesemia and acneiform rash in patients with metastatic colorectal cancer (mCRC). We examined the relationship between the incidence of such adverse events and the therapeutic effect. METHODS: Thirty-four mCRC patients receiving anti -EGFR monoclonal antibody as a first-line therapy during April 2012 to March 2015 were the subjects of the present study. The symptoms of hypomagnesemia and acneiform rash were graded in accordance with the Common Terminology Criteria for Adverse Events, v4.0. RESULTS: The incidence rates of hypomagnesemia (all grades) and the acneiform rash (≥grade 2) were 29%and 50%, respectively. Eight patients (24%) exhibited both of these adverse events. The tumor response rate was notable, as it was significantly higher in patients who experienced both of these adverse events compared to those who did not(88% vs 38% for complete response plus partial response, p=0.039). However, the tumor response rate tended to be higher, although not significantly, in patients with either of these adverse events compared to those without it. CONCLUSION: Concurrent onset of hypomagnesemia and acneiform rash may become a reliable factor capable of predicting the therapeutic effect of anti-EGFR monoclonal antibody.

RESUMO

PURPOSE: Anti-EGFR monoclonal antibody is effective for KRAS wild-type metastatic colorectal cancer (mCRC), but frequently causes several adverse reactions, including hypomagnesemia and skin disorders. The present study was designed to investigate the relationship between the incidence of adverse reactions and therapeutic effects in mCRC patients receiving anti-EGFR monoclonal antibody in combination with first-line chemotherapy. METHODS: Forty-three mCRC patients who received cetuximab or panitumumab between April 2012 and December 2015 were the subjects of the present study. All patients were pretreated with oral minocycline in combination with skin treatment using moisturizer for prevention of skin rash. Hypomagnesemia and acneiform rash were graded according to the Common Terminology Criteria for Adverse Events, version 3.0. Overall response rate (ORR) and time to treatment failure (TTF) were compared between patients with and without these adverse events. RESULTS: The incidence rates of hypomagnesemia and acneiform rash were 32.6 % (grade 1: 20.9 %, grade 2: 11.6 %) and 93.0 % (grade 1: 41.9 %, grade 2: 41.9 %, grade 3: 9.3 %), respectively. ORR was significantly higher in patients with hypomagnesemia than in those without it (71.4 vs 34.5 %, P = 0.048). Median TTF tended to be longer, though not significantly, in patients with hypomagnesemia than in those without it. However, no significant difference in both ORR and median TTF was observed between patients with and without acneiform rash. CONCLUSION: Hypomagnesemia may become a predicting factor for therapeutic effects of anti-EGFR monoclonal antibody in mCRC patients.
