RESUMEN
BACKGROUND/AIM: We previously reported that patients with metastatic colorectal cancer (mCRC) and baseline liver metastasis are at a higher risk of developing grade ≥2 overall skin toxicities when treated with anti-epidermal growth factor receptor (EGFR) monoclonal antibody. This study aimed to identify additional factors associated with skin toxicities induced by anti-EGFR treatment in patients with liver metastatic CRC. PATIENTS AND METHODS: Patients with liver metastatic CRC who initially received anti-EGFR monoclonal antibody-containing treatment (n=77) were retrospectively assessed. The primary endpoint was to identify the factor(s) responsible for the development of grade ≥2 overall skin toxicities. Additionally, factors for grade ≥2 rash and paronychia were evaluated. RESULTS: The incidence of grade ≥2 overall skin symptoms, rash, and paronychia was 62.3%, 31.2%, and 28.6%, respectively. Multivariate Cox proportional hazard regression analyses revealed that age <65 years and anemia were independent baseline risk factors for grade ≥2 overall skin toxicities (adjusted hazard ratio 2.09, 95% confidence interval=1.10-3.97, p=0.02 for age; 2.36, 1.20-4.61, p=0.01 for anemia). In contrast, combination prophylaxis using systemic minocycline and corticosteroid ointment was a preventive factor (0.47, 0.25-0.88, p=0.02). Males and age <65 years were baseline risk factors for grade ≥2 rash, and combination prophylaxis was identified as a preventive factor. No factors were identified for paronychia. CONCLUSION: Age <65 years and anemia were identified as independent baseline risk factors. Additionally, combination prophylaxis was found to be a preventive factor against anti-EGFR monoclonal antibody-induced grade ≥2 overall skin toxicities in patients with liver metastatic CRC.

Background/Aim: Radium-223 treatment reduces the risk of death in patients with metastatic castration-resistant prostate cancer (CRPC). This study analyzed the prognostic factors in patients treated with radium-223 dichloride. Patients and Methods: Patients who received radium-223 dichloride were retrospectively analyzed. Prostate-specific antigen (PSA) response and alkaline phosphatase (ALP) decline rates were analyzed. Overall survival (OS) was evaluated using Kaplan-Meier curves, and prognostic factors for OS were assessed using Cox proportional hazards analysis. Results: Fifty-six patients were included in the study. The five-year OS rate in patients after diagnosis of CRPC was 62.2% [95% confidence interval (CI)=27.55-112.45], while the five-year OS rate in patients at the initiation of radium-223 treatment was 21.3% (95%CI=17.20-36.79). Six patients (11.1%) had a >50% PSA decline rate, and 10 (17.9%) had a >50% ALP decline rate. Cox proportional hazards analysis showed that PSA levels at the initiation of radium-223 treatment [hazard ratio (HR)=1.00; 95%CI=1.00-1.00; p=0.0054] and Gleason Pattern (GP) 5 (HR=5.42; 95%CI=1.08-27.27; p=0.0400) were associated with OS. Patients with GP 5 had a significantly poorer prognosis compared with patients with a GP ≤4. Early administration of radium-223 as a first- or second-line treatment was not associated with OS compared with late administration of radium-223 as a third-line or later treatment. Conclusion: GP 5 and high PSA levels at radium-223 initiation were associated with worse OS. Radium-223 as first- or second-line treatment was not associated with OS. Therefore, a treatment strategy for CRPC based on GP 5 is needed.
RESUMEN
PURPOSE: Anthracycline-cyclophosphamide followed by docetaxel-containing chemotherapy is effective for perioperative breast cancer treatment. However, these treatments frequently induce oral mucositis (OM), with an incidence ranging from 20 to 50%. The association of OM development between different chemotherapeutic treatments remains unclear. Consequently, this study aimed to compare OM development during docetaxel-containing chemotherapy between patients with and without OM experience during previous anthracycline-cyclophosphamide treatments to assess the association between OM development and treatment regimens. METHODS: Seventy-two patients with breast cancer receiving anthracycline-cyclophosphamide followed by docetaxel-containing chemotherapy as a perioperative treatment were categorized into the control (no prior OM experience with anthracycline-cyclophosphamide) and OM-experience (OM development during previous treatment) groups and retrospectively evaluated. The primary endpoint was the incidence of all-grade OM in the first docetaxel-containing chemotherapy cycle. Additionally, the incidences of OM and dysgeusia during all treatment cycles and factors associated with the incidence of OM were evaluated. RESULTS: The incidence of all-grade OM in the first cycle was significantly higher in the OM-experience group (54.2%) than in the control group (10.4%; P < 0.0001). Furthermore, its incidence in all treatment cycles was higher in the OM-experience group (66.7%) than in the control group (12.5%, P < 0.0001). However, the incidence of dysgeusia did not differ between the groups. Multivariate logistic regression analysis revealed OM experience during previous anthracycline-cyclophosphamide treatment and concomitant pertuzumab use as independent risk factors for OM development in subsequent docetaxel-containing chemotherapy. CONCLUSION: Our study suggests that patients experiencing OM with anthracycline-cyclophosphamide during perioperative breast cancer treatment exhibit symptoms following subsequent docetaxel-containing chemotherapy.

Although carboplatin (CBDCA) is classified as a moderately emetogenic agent, the majority of guidelines recommend the use of a neurokinin-1 receptor antagonist in addition to a 5-hydroxytryptamine type 3 receptor antagonist with dexamethasone (DEX) for CBDCA-containing chemotherapy because of its higher emetogenic risk. However, the additional efficacy of aprepitant (APR) in CBDCA-containing treatment remains controversial, and data on multiple-day treatments are limited. Etoposide (ETP) was administered on days 1-3 in the CBDCA + ETP regimen, and it is important to evaluate suitable antiemetic therapy for the regimen. Therefore, we evaluated the efficacy of additional APR in CBDCA + ETP. Patients were divided into two groups and retrospectively evaluated. One was the control group, which was prophylactically administered palonosetron (PALO) and DEX, and the other was the APR group, which received APR orally with PALO and DEX. The primary endpoint was complete response (CR) between the groups. The overall CR rates were 75.0 and 76.4% in the control and APR groups, respectively, with no significant difference (p = 1.00). In the acute phase, it was 88.9 and 97.2%, respectively, and 86.1 and 79.2% in the delayed phase, respectively, without significant differences (p = 0.10 and 0.38, respectively). The incidence and severity of nausea, vomiting, and anorexia were not significantly different between the two groups in the acute and delayed phases. Our findings suggest that combining APR with PALO and DEX does not improve the CR rate in CBDCA + ETP therapy.

Hand-foot syndrome (HFS) is a frequently occurring and treatment-requiring adverse effect of docetaxel. We previously reported that systemic dexamethasone (DEX) prevents the other docetaxel-induced adverse inflammatory effects in a dose-dependent manner. This study aimed to evaluate the dose-dependent efficacy of systemic DEX in attenuating HFS in patients with breast cancer receiving docetaxel. Patients with breast cancer receiving docetaxel (75 mg/m2)-containing regimens (n = 111) were divided into 4 and 8 mg/day DEX groups, with each DEX dose administered on days 2-4, and analyzed retrospectively. Development of all-grade HFS in all treatment cycles was significantly lower in the 8 mg group (50.0%) than in the 4 mg group (73.0%, P = 0.03), with primary endpoint accomplishment. Moreover, its development in the first cycle was also lower in the 8 mg group than in the 4 mg group. These results were confirmed in a propensity score-matched population. Logistic regression analysis suggested higher DEX dosage as an independent preventive factor (adjusted odds ratio 0.35; 95% confidence interval 0.14-0.86, P = 0.02 for all cycles; 0.26, 0.11-0.63, P = 0.003 for the first cycle). Our study suggests that systemic DEX prevents the occurrence of docetaxel-induced HFS in patients with breast cancer in a dose-dependent manner in a real-world setting.

BACKGROUND: Methotrexate (MTX) is partially metabolized by aldehyde oxidase (AOX) in the liver and its clinical impact remains unclear. In this study, we aimed to demonstrate how AOX contributes to MTX-induced hepatotoxicity in vitro and clarify the relationship between concomitant AOX inhibitor use and MTX-associated liver injury development using the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS). METHODS: We assessed intracellular MTX accumulation and cytotoxicity using HepG2 cells. We used the FAERS database to detect reporting odds ratio (ROR)-based MTX-related hepatotoxicity event signals. RESULTS: AOX inhibition by AOX inhibitor raloxifene and siRNA increased the MTX accumulation in HepG2 cells and enhanced the MTX-induced cell viability reduction. In the FAERS analysis, the ROR for MTX-related hepatotoxicity increased with non-overlap of 95% confidence interval when co-administered with drugs with higher Imax, u (maximum unbound plasma concentration)/IC50 (half-maximal inhibitory concentration for inhibition of AOX) calculated based on reported pharmacokinetic data. CONCLUSION: AOX inhibition contributed to MTX accumulation in the liver, resulting in increased hepatotoxicity. Our study raises concerns regarding MTX-related hepatotoxicity when co-administered with drugs that possibly inhibit AOX activity at clinical concentrations.

Introduction: Hand, foot, and mouth disease generally occurs in children. In rare cases, hand, foot, and mouth disease affects the testicles. Case presentation: A 29-year-old man presented to our emergency department with testicular pain for several days after the onset of hand, foot, and mouth disease. Ultrasonography revealed hypoechoic mass-like areas in the right testis. A mild inflammatory response was noted, tumor markers and urinary data were normal, and tests for infection were all negative. Antibiotics were initiated and ultrasonography was performed in every subsequent examination. Testicular pain disappeared 6 months later. Conclusion: We encountered a rare case of a testicular lesion related to hand, foot, and mouth disease that was successfully treated. The careful selection of treatment for testicular pain and scrotal enlargement in young adult males, such as surgery and symptomatic treatment, based on their medical history and laboratory findings, is important.
RESUMEN
L-Lactate transport via monocarboxylate transporters (MCTs) in the central nervous system, represented by the astrocyte-neuron lactate shuttle (ANLS), is crucial for the maintenance of brain functions, including memory formation. Previously, we have reported that MCT1 contributes to L-lactate transport in normal human astrocytes. Therefore, in this study, we aimed to identify transporters that contribute to L-lactate transport in human neurons. SH-SY5Y cells, which are used as a model for human neurons, were differentiated using all-trans-retinoic acid. L-Lactate uptake was measured using radiolabeled L-lactate, and the expression of MCT proteins was confirmed Western blotting. L-Lactate transport was pH-dependent and saturated at high concentrations. Kinetic analysis suggested that L-lactate uptake was biphasic. Furthermore, MCT1, 2 selective inhibitors inhibited L-lactate transport. In addition, the expression of MCT1 and 2 proteins, but not MCT4, was confirmed. In this study, we demonstrated that MCT1 and 2 are major contributors to L-lactate transport in differentiated human neuroblastoma SH-SY5Y cells from the viewpoint of kinetic analysis. These results lead to a better understanding of ANLS in humans, and further exploration of the factors that can promote MCT1 and 2 functions is required.

Regorafenib is the first multikinase inhibitor for treating metastatic colorectal cancer (mCRC). Proteinuria is a frequently encountered adverse effect, regardless of prior administration of vascular endothelial growth factor inhibitors. Herein, we aimed to assess the impact of baseline preexisting proteinuria on regorafenib-induced problematic proteinuria during real-world mCRC therapy. Patients with mCRC receiving regorafenib (n = 100) were retrospectively assessed and divided into control and preexisting proteinuria (baseline grade of 1-2) groups. The primary endpoint was the development of grade ≥ 2 (grade ≥ 3 in case of baseline grade 2 patients) proteinuria. Propensity score-matching was performed to confirm the robustness of primary analyses. Defined proteinuria occurred in 30.7 and 57.9% of patients in the control and preexisting proteinuria groups, respectively, with significant differences in the all-patient population (P = 0.01). The preexisting proteinuria group exhibited significant defined proteinuria development within 7 days of regorafenib initiation, grade ≥ 3 symptoms, and treatment suspension owing to proteinuria. Similar results were obtained in the propensity score-matched population. According to multivariate logistic regression analysis, baseline proteinuria was a singular risk factor for defined proteinuria development (adjusted odds ratio; 3.76, 95% confidence interval; 1.45-9.75, P = 0.007). Collectively, our study revealed that patients with preexisting proteinuria develop regorafenib-induced proteinuria degradation.

OBJECTIVE: Irinotecan (IRI) is an anticancer drug that is frequently used to treat colorectal, gastric, and pancreatic cancers. Its side effects include cholinergic symptoms, such as diarrhea, abdominal pain, nausea, and hyperhidrosis. Anticholinergic medicines are frequently used for treatment or prophylaxis; however, the risk factors for the failure of a single prophylactic anticholinergic administration remain unclear. Moreover, an appropriate anticholinergic drug for prophylaxis remains unknown. Thus, we aimed to identify the risk factors associated with the failure of a single prophylactic dose of anticholinergic drugs for IRI-induced cholinergic symptoms and to evaluate the usefulness of multiple prophylactic doses of anticholinergic drugs. MATERIALS AND METHODS: Patients who underwent IRI treatment for colorectal, gastric, or pancreatic cancer and received prophylactic anticholinergic drugs for IRI-induced cholinergic symptoms (n = 135) were retrospectively evaluated. Univariate and multivariate logistic regression analyses were performed to identify the risk factors for failure of a single prophylactic dose of anticholinergic drugs. We also evaluated the efficacy of multiple prophylactic anticholinergic drug administration. RESULTS: Based on univariate and multivariate analyses, colorectal cancer, female sex, and prophylactic use of scopolamine butyl bromide were identified as risk factors for failure of a single prophylactic dose of anticholinergic drugs. The efficacy of multiple prophylactic doses was confirmed to be 95% of the patients who had a single prophylactic failure due to temporary effect but symptom appearance after a certain period of time (wearing-off). CONCLUSION: We determined that colorectal cancer, female sex, and prophylactic use of scopolamine butyl bromide were risk factors associated with the failure of a single prophylactic dose of anticholinergic drugs, and that multiple prophylactic doses for wearing-off can be a promising method.

BACKGROUND/AIM: Cisplatin-induced nephrotoxicity (CIN) is one of the most attention-requiring adverse effects. We have reported that diabetes mellitus significantly increases the incidence of CIN in a short hydration method in real-world lung cancer treatment. However, the effect of prediabetes on CIN development remains unclear. This study investigated whether patients with prediabetes exhibit CIN at a greater rate during real-world cisplatin-including treatments as a subgroup analysis. PATIENTS AND METHODS: This retrospective observational study enrolled patients with lung cancer receiving cisplatin treatment (≥75 mg/m2) from May 2014 to January 2021 (n=169). Patients were divided into a prediabetes group (baseline HbA1c 5.7-6.4%) and a control group (baseline HbA1c <5.7%). The primary endpoint of this study was the incidence of CIN in all treatment cycles between the two groups. We also assessed variations in serum creatinine (SCr) levels and creatinine clearance (CCr). RESULTS: CIN occurred in 4.7% of controls and 8.3% of patients with prediabetes in all cycles, with no significant difference (p=0.37). In contrast, variation of SCr levels and CCr was significantly worse in the prediabetes group [median variation level (range) 0.11 mg/dl (-0.11-0.46 mg/dl) and 0.12 mg/dl (-0.02-1.08 mg/d) in controls and prediabetes, p=0.04 for SCr; -12.9 ml/min (-54.1-4.9 ml/min) and -16.3 ml/min (-49.4-3.0 ml/min), p=0.02 for CCr, respectively]. These results were also confirmed during the first cycle of treatment. CONCLUSION: Patients with prediabetes did not develop problematic CIN, although they exhibited significant increases in SCr and decreases in CCr.

Immune checkpoint inhibitors have drastically improved cancer treatment. However, they may induce immune-related adverse events (irAEs). Here, we report a case of significantly delayed rheumatic irAEs (Rh-irAEs) with prior possible temporary neutropenic irAEs in a patient with atezolizumab-treated non-small-cell lung cancer and its management. A man in his sixties received atezolizumab monotherapy as the sixth-line treatment. He experienced an infusion-related reaction (fever) during the first cycle. On day 22 of cycle 2, grade 4 neutropenia suddenly appeared, but it disappeared on the next day. Cycle 3 was initiated after seven days; the patient did not exhibit any symptoms for approximately 500 days. However, on day 534 (day 1 of cycle 21), the patient complained of pain in the shoulders, back, and wrists. On day 644, the shoulder and back pain worsened with obvious swelling of the fingers. We thus suspended treatment and consulted a rheumatologist. A diagnosis of polyarthritis with active tenosynovitis was made based on joint ultrasound and laboratory tests. Prednisolone 15 mg attenuated the symptoms, allowing suspension of analgesics; however, dose reduction from 15 mg/day was difficult because of symptom flares. Finally, iguratimod 25 mg twice daily was initiated on day 764; prednisolone was reduced to 10 mg without flares, and its dosage was slowly reduced to 5 mg/day. Although irAEs exhibit multisystem features, delayed development of polyarthritis with active tenosynovitis after possible temporary neutropenic irAEs is rare. Thus, irAEs need to be monitored for a long time in patients with suspected irAE development even if it appears transiently.
RESUMEN
BACKGROUND: Premature mortality, frequent relapse that easily leads to hospitalization, and discontinuous employment are key challenges for the treatment of schizophrenia. We evaluated risk factors for important clinical outcomes (death, hospitalization, resignation, and sick leave from work) in patients with schizophrenia in Japan. METHODS: A nested case-control study was conducted for patients with schizophrenia identified in a Japanese claims database. For each outcome, the case was matched with up to four controls of the same age, sex, index year, and enrollment status (employee or dependent family). Potential risk factors were defined by prescriptions or diagnoses within 3 months prior to or in the month of the event. The association among potential risk factors and each outcome was evaluated using multivariable conditional logistic regression analysis with stepwise variable selection. RESULTS: The number of cases and eligible patients for each outcome were 144 and 38,451 (death), 1,520 and 35,225 (hospitalization), 811 and 18,770 (resignation), and 4,590 and 18,770 (sick leave), respectively. Depression was a risk factor for death (odds ratio [OR]: 1.92; 95% confidence interval [CI]: 1.12, 3.29), hospitalization (OR: 1.22; 95% CI: 1.05, 1.42), and sick leave from work (OR: 1.46; 95% CI: 1.36, 1.57). Other risk factors for death were hospitalization history, Charlson Comorbidity Index (CCI) score, and prescription for laxatives. Prescriptions for hypnotics, laxatives, and anticholinergics were risk factors for hospitalization. Prescriptions for hypnotics and anticholinergics were risk factors for resignation. CCI score, prescription for hypnotics, laxatives, and antidiabetics were risk factors for sick leave from work. CONCLUSIONS: Our findings suggest that depression and some physical symptoms, such as constipation and extrapyramidal symptoms, are risk factors for important clinical outcomes in patients with schizophrenia. Attention should be paid to both depression and physical symptoms for the treatment of schizophrenia.

OBJECTIVES: Aldehyde oxidase (AO) is a molybdenum-containing redox enzyme similar to xanthine oxidase that is involved in the thiopurine metabolism. This study investigated the effects of drug-drug interactions (DDIs) between azathioprine (AZA) and AO inhibitors on hematologic and hepatic disorders using the U.S. Food and Drug Administration Adverse Event Reporting System and the Japanese Adverse Drug Event Report database. METHODS: The presence of DDI was assessed using the interaction signal scores (ISSs) calculated via the reporting odds ratios and 95% confidence intervals. The study used reports of 'azathioprine' as a suspect drug for adverse effects. AO inhibitors were selected based on previous in vitro reports. RESULTS: Some drugs tested positive for ISSs in each database and type of adverse effect (hematologic or hepatic disorder) analysis. Among these drugs, chlorpromazine, clozapine, hydralazine, and quetiapine could inhibit AZA metabolism via AO, given the previously reported clinical blood concentration and inhibitory effects of each drug. CONCLUSION: Concomitant use of AO inhibitors increased the signals for AZA-induced adverse effects. To date, no studies have evaluated the clinical importance of AO as a drug-metabolizing enzyme, and further in vitro and clinical research is needed to clarify the contribution of AO to the pharmacokinetics of thiopurines.

BACKGROUND: Anti-epidermal growth factor receptor (EGFR) antibodies often cause skin toxicities. Preemptive skin treatments using systemic antibiotics with or without topical steroid are reportedly effective although the most suitable method remains unclear. This study aimed to determine whether combination prophylaxis using systemic minocycline and topical steroid is superior to minocycline alone in a real-world metastatic colorectal cancer (mCRC) treatment. METHODS: Patients with mCRC (n = 87) who received anti-EGFR monoclonal antibodies were retrospectively assessed. The primary objective was to compare the incidence of grade ≥ 2 overall skin toxicities during all treatment periods between the control group receiving prophylactic minocycline 100 mg/day, and the combination prophylaxis group receiving minocycline 100 mg/day + topical steroid. The incidence of each skin symptom was also evaluated. RESULTS: The incidence of grade ≥ 2 overall skin toxicities was 63.6% in the control and 56.9% in the combination groups, with no significant difference (P = 0.63). Similarly, the incidence of grade ≥ 2 dry skin, fissures, paronychia, and pruritus did not significantly differ. In addition, incidence of all-grade skin toxicities was not different. However, the incidence of grade ≥ 2 papulopustular rashes was significantly lower in the combination group (23.1% vs. 50.0%, P = 0.03). Propensity score-matched analysis supported these results. Multivariate logistic regression analysis showed no significant association between combination prophylaxis and grade ≥ 2 overall skin toxicities, but it did show a reduction in grade ≥ 2 papulopustular rashes. CONCLUSION: Adding topical steroids to systemic minocycline did not mitigate grade ≥ 2 overall skin toxicities induced by anti-EGFR antibodies; however, it significantly improved papulopustular rashes.

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) are common adverse events in patients undergoing emetogenic chemotherapy. Palonosetron, a second-generation 5-hydroxytryptamine-3 receptor antagonist (5-HT3 RA), has demonstrated non-inferiority to first-generation 5-HT3 RAs for CINV in pediatric patients. Although palonosetron has a long half-life and prolonged antiemetic action, its efficacy against delayed CINV in pediatric patients is not well understood. Therefore, this meta-analysis of randomized controlled trials (RCTs) aimed to evaluate the efficacy of palonosetron for delayed CINV in pediatric patients. METHODS: A literature search of MEDLINE/PubMed, Embase, Cochrane Library, and Web of Science databases was performed. A meta-analysis was performed using forest plots, and risk ratios (RRs) and 95% confidence intervals (CIs) were calculated. A funnel plot was constructed to explore publication bias. RESULTS: The literature search retrieved 842 records, of which 23 full-text articles were assessed, including six RCTs. Meta-analysis of four RCTs that reported on the complete response (CR: defined as no emesis and no rescue medication) rate for delayed CINV revealed that palonosetron was statistically superior to first-generation 5-HT3 RAs (RR = 1.21 [95% CI 1.09-1.35]; p < 0.01). Although the number of studies included was small, no publication bias was observed in the funnel plots. In addition, the CR rate for overall and acute CINV was also significantly higher for palonosetron (RR = 1.25 [95% CI 1.01-1.54]; p = 0.04 and RR = 1.06 [95% CI 1.01-1.12]; p = 0.03, respectively). CONCLUSION: Palonosetron is effective in the prophylaxis of delayed CINV in pediatric patients.

Treatment using docetaxel (DOC) and ramucirumab (RAM) is an effective regimen in second or later line advanced non-small cell lung carcinoma (NSCLC) treatment. However, it induces severe adverse effects, resulting in treatment reduction such as dose reduction and/or discontinuation. This study aimed to reveal the factor(s) associated with treatment reduction in DOC + RAM. We retrospectively evaluated patients with advanced NSCLC (n = 155). Treatment reduction of the second course due to severe adverse effects was conducted in 25.8% of the participants, and relative dose intensity at the second course was 95.7 ± 8.4% for DOC and 91.9 ± 24.8% for RAM. Multivariate logistic regression analyses identified that baseline anemia and prophylactic granulocyte colony-stimulating factor (G-CSF) administration are preventive factors for the reduction (adjusted odds ratio, 0.29; 95% confidence interval, 0.12-0.66; P = 0.004 for baseline anemia, 0.18; 0.08-0.42; P < 0.0001 for prophylactic G-CSF administration). The primary cause of the reduction was febrile neutropenia, and the same factors were identified. Our study revealed that patients with baseline anemia and prophylactic G-CSF administration have less risk for treatment reduction in DOC + RAM for NSCLC treatment.

The occurrence of cisplatin (CDDP)-induced nephrotoxicity (CIN) has decreased with advancements in supportive care. In contrast, we reported that baseline diabetes mellitus (DM) complications significantly worsen CIN. This study aimed to determine further risk factors associated with CIN development in DM patients. Patients with thoracic cancer requiring DM pharmacotherapy, who received CDDP (≥ 60 mg/m2)-containing regimens using the short hydration method (n = 140), were enrolled in this retrospective multicenter observational study. The primary endpoint of the present study was the elucidation of risk factors (patient factors, DM medication influence, and treatment-related factors) associated with CIN development in patients with DM. Cisplatin-induced nephrotoxicity occurred in 22.1% of patients with DM. The median worst variation of serum creatinine levels and creatinine clearance (worst level - baseline level) was 0.16 mg/dL (range: - 0.12-1.41 mg/dL) and - 15.9 mL/min (- 85.5-24.3 mL/min), respectively. Multivariate logistic regression analyses identified female sex as the singular risk factor for CIN development in the DM population (adjusted odds ratio; 2.87, 95% confidence interval; 1.08-7.67, P = 0.04). Diabetes mellitus medication and treatment-related factors did not affect CIN development. In conclusion, our study revealed that female sex is significantly associated with CIN development in patients with DM and thoracic cancer.

BACKGROUND: There is little evidence regarding risk prediction for surgical site infection (SSI) after lower third molar (L3M) surgery. METHODS: We conducted a nested case-control study to develop a multivariable logistic model for predicting the risk of SSI after L3M surgery. Data were obtained from Hokkaido University Hospital from April 2013 to March 2020. Multiple imputation was applied for the missing values. We conducted decision tree (DT) analysis to evaluate the combinations of factors affecting SSI risk. RESULTS: We identified 648 patients. The final model retained the available distal space (Pell & Gregory II [p = 0.05], Pell & Gregory III [p < 0.01]), depth (Pell & Gregory B [p < 0.01], Pell & Gregory C [p < 0.01]), surgeon's experience (3-10 years [p = 0.25], <3 years [p < 0.01]), and simultaneous extraction of both L3M [p < 0.01]; the concordance-statistic was 0.72. The DT analysis demonstrated that patients with Pell and Gregory B or C and simultaneous extraction of both L3M had the highest risk of SSI. CONCLUSIONS: We developed a model for predicting SSI after L3M surgery with adequate predictive metrics in a single center. This model will make the SSI risk prediction more accessible.
RESUMEN
PURPOSE: Anti-epidermal growth factor receptor (anti-EGFR) monoclonal antibodies are effective in treating RAS wild-type metastatic colorectal cancer (mCRC). However, their administration induces skin toxicity, markedly reducing patients' quality of life. This study is aimed at identifying the risk factors associated with anti-EGFR monoclonal antibody-induced skin toxicities. METHODS: Patients with mCRC (n = 116) who received anti-EGFR monoclonal antibody treatment were retrospectively evaluated. Primary endpoint was evaluation of the risk factors for grade ≥ 2 overall skin toxicities during all the treatment periods. Furthermore, factors associated with each grade ≥ 2 skin symptoms were assessed. RESULTS: Incidence of total grade ≥ 2 skin toxicity symptoms was 61.2%, and those of grade ≥ 2 rash, dry skin, fissures, and paronychia were 34.5%, 25.9%, 20.7%, and 25.0%, respectively. Multivariate logistic regression analyses revealed that liver metastasis was an independent risk factor for overall grade ≥ 2 skin toxicities (adjusted odds ratio [OR], 2.88; 95% confidence interval [CI], 1.22-6.78; P = 0.02) and prophylactic administration of antibiotics as a preventive factor (OR 0.10; 95%CI 0.01-0.91; P = 0.04). For grade ≥ 2 rash, prophylactic use of systemic antibiotics and topical steroid ointment was a preventive factor (OR 0.37; 95%CI 0.16-0.89; P = 0.03). Moreover, liver metastasis (OR 8.37; 95%CI 1.98-35.47; P = 0.004) and prophylactic administration of antibiotics (OR 0.15; 95%CI 0.03-0.76; P = 0.02) were significantly associated with grade ≥ 2 paronychia. CONCLUSION: Liver metastasis was suggested to be a risk factor for the incidence of overall grade ≥ 2 skin toxicities; moreover, preemptive systemic antibiotic administration drastically decreased this risk during all periods of anti-EGFR treatment for mCRC.
