RESUMEN
BACKGROUND: Upadacitinib, an oral selective Janus kinase (JAK) inhibitor, is under investigation for the treatment of Crohn's disease. METHODS: In two phase 3 induction trials (U-EXCEL and U-EXCEED), we randomly assigned patients with moderate-to-severe Crohn's disease to receive 45 mg of upadacitinib or placebo (2:1 ratio) once daily for 12 weeks. Patients who had a clinical response to upadacitinib induction therapy were randomly assigned in the U-ENDURE maintenance trial to receive 15 mg of upadacitinib, 30 mg of upadacitinib, or placebo (1:1:1 ratio) once daily for 52 weeks. The primary end points for induction (week 12) and maintenance (week 52) were clinical remission (defined as a Crohn's Disease Activity Index score of <150 [range, 0 to 600, with higher scores indicating more severe disease activity]) and endoscopic response (defined as a decrease in the Simple Endoscopic Score for Crohn's Disease [SES-CD; range, 0 to 56, with higher scores indicating more severe disease] of >50% from baseline of the induction trial [or for patients with an SES-CD of 4 at baseline, a decrease of ≥2 points from baseline]). RESULTS: A total of 526 patients underwent randomization in U-EXCEL, 495 in U-EXCEED, and 502 in U-ENDURE. A significantly higher percentage of patients who received 45-mg upadacitinib than those who received placebo had clinical remission (in U-EXCEL, 49.5% vs. 29.1%; in U-EXCEED, 38.9% vs. 21.1%) and an endoscopic response (in U-EXCEL, 45.5% vs. 13.1%; in U-EXCEED, 34.6% vs. 3.5%) (P<0.001 for all comparisons). At week 52 in U-ENDURE, a higher percentage of patients had clinical remission with 15-mg upadacitinib (37.3%) or 30-mg upadacitinib (47.6%) than with placebo (15.1%), and a higher percentage had an endoscopic response with 15-mg upadacitinib (27.6%) or 30-mg upadacitinib (40.1%) than with placebo (7.3%) (P<0.001 for all comparisons). Herpes zoster infections occurred more frequently in the 45-mg and 30-mg upadacitinib groups than in the respective placebo groups, and hepatic disorders and neutropenia were more frequent in the 30-mg upadacitinib group than in the other maintenance groups. Gastrointestinal perforations developed in 4 patients who received 45-mg upadacitinib and in 1 patient each who received 30-mg or 15-mg upadacitinib. CONCLUSIONS: Upadacitinib induction and maintenance treatment was superior to placebo in patients with moderate-to-severe Crohn's disease.

BACKGROUND: Mirikizumab, a p19-directed antibody against interleukin-23, showed efficacy in the treatment of ulcerative colitis in a phase 2 trial. METHODS: We conducted two phase 3, randomized, double-blind, placebo-controlled trials of mirikizumab in adults with moderately to severely active ulcerative colitis. In the induction trial, patients were randomly assigned in a 3:1 ratio to receive mirikizumab (300 mg) or placebo, administered intravenously, every 4 weeks for 12 weeks. In the maintenance trial, patients with a response to mirikizumab induction therapy were randomly assigned in a 2:1 ratio to receive mirikizumab (200 mg) or placebo, administered subcutaneously, every 4 weeks for 40 weeks. The primary end points were clinical remission at week 12 in the induction trial and at week 40 (at 52 weeks overall) in the maintenance trial. Major secondary end points included clinical response, endoscopic remission, and improvement in bowel-movement urgency. Patients who did not have a response in the induction trial were allowed to receive open-label mirikizumab during the first 12 weeks of the maintenance trial as extended induction. Safety was also assessed. RESULTS: A total of 1281 patients underwent randomization in the induction trial, and 544 patients with a response to mirikizumab underwent randomization again in the maintenance trial. Significantly higher percentages of patients in the mirikizumab group than in the placebo group had clinical remission at week 12 of the induction trial (24.2% vs. 13.3%, P<0.001) and at week 40 of the maintenance trial (49.9% vs. 25.1%, P<0.001). The criteria for all the major secondary end points were met in both trials. Adverse events of nasopharyngitis and arthralgia were reported more frequently with mirikizumab than with placebo. Among the 1217 patients treated with mirikizumab during the controlled and uncontrolled periods (including the open-label extension and maintenance periods) in the two trials, 15 had an opportunistic infection (including 6 with herpes zoster infection) and 8 had cancer (including 3 with colorectal cancer). Among the patients who received placebo in the induction trial, 1 had herpes zoster infection and none had cancer. CONCLUSIONS: Mirikizumab was more effective than placebo in inducing and maintaining clinical remission in patients with moderately to severely active ulcerative colitis. Opportunistic infection or cancer occurred in a small number of patients treated with mirikizumab.

Posttransplant lymphoproliferative disorder (PTLD) poses a significant concern in Epstein-Barr virus (EBV)-negative patients transplanted from EBV-positive donors (EBV R-/D+). Previous studies investigating the association between different induction agents and PTLD in these patients have yielded conflicting results. Using the Organ Procurement and Transplant Network database, we identified EBV R-/D+ patients >18 years of age who underwent kidney-alone transplants between 2016 and 2022 and compared the risk of PTLD with rabbit antithymocyte globulin (ATG), basiliximab, and alemtuzumab inductions. Among the 6620 patients included, 64.0% received ATG, 23.4% received basiliximab, and 12.6% received alemtuzumab. The overall incidence of PTLD was 2.5% over a median follow-up period of 2.9 years. Multivariable analysis demonstrated that the risk of PTLD was significantly higher with ATG and alemtuzumab compared with basiliximab (adjusted subdistribution hazard ratio [aSHR] = 1.98, 95% confidence interval [CI] 1.29-3.04, P = .002 for ATG and aSHR = 1.80, 95% CI 1.04-3.11, P = .04 for alemtuzumab). However, PTLD risk was comparable between ATG and alemtuzumab inductions (aSHR = 1.13, 95% CI 0.72-1.77, P = .61). Therefore, the risk of PTLD must be taken into consideration when selecting the most appropriate induction therapy for this patient population.

Thromboembolism (TE) is associated with reduced survival in pediatric acute lymphoblastic leukemia (ALL). It has been hypothesized that TE might signal leukemic aggressiveness. The objective was to determine risk factors for TE during ALL induction (TEind ) therapy and whether TEind is associated with treatment refractoriness. This retrospective cohort study using the population-based Cancer in Young People Canada (CYP-C) registry included children <15 years of age diagnosed with ALL (2000-2019) and treated at one of 12 Canadian pediatric centers outside of Ontario. Univariate and multivariable logistic regression models were used to determine risk factors for TEind and whether TEind predicted induction failure and ALL treatment intensification. The impact of TEind on overall and event-free survival was estimated using Cox proportional hazard regression models. The study included 2589 children, of which 45 (1.7%) developed a TEind . Age (<1 year and ≥10 years vs. 1-<10 years), T-cell phenotype, high-risk ALL, and central nervous system involvement were all associated with TEind in univariate analysis. Age and T-cell phenotype remained independent predictors of TEind in multivariable analysis. Induction failure occurred in 53 patients (2.1%). TEind was not associated with induction failure (OR: not estimable) or treatment intensification (adjusted OR [95% CI]: 0.66 [0.26-1.69]). TEind was independently associated with overall survival (adjusted HR [95% CI]: 2.54 [1.20-5.03]) but not event-free survival (adjusted HR [95% CI] 1.86 [0.98-3.51]). In this population-based study of children treated with contemporary chemotherapy protocols, TEind was associated with age and T-cell phenotype and mortality but did not predict induction failure.

Atypical hemolytic uremic syndrome (aHUS) is a complement-mediated thrombotic microangiopathy sometimes associated with germline variants in genes of the complement system. Clinical findings of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury arise due to aberrant complement protein activation in the circulation. A 13-month-old boy with metastatic neuroblastoma (NB) developed aHUS during his first cycle of induction chemotherapy with germline testing revealing a complement factor H (CFH) gene mutation, currently classified as a variant of uncertain significance (VUS). Now he is in disease remission after successful complement blockade therapy, thus highlighting a unique presentation of aHUS in a patient with newly diagnosed NB.

Patients with high-risk neuroblastoma (HR-NB) exhibit suboptimal 5-year survival rates, leading to a widespread international preference for high-intensity chemotherapeutic regimens in these children. We analyzed the incidence and risk factors for complications during induction chemotherapy in children with HR-NB and tried to assist clinicians in predicting such complications and optimizing therapeutic strategy. The clinical data of children with HR-NB admitted to our hospital from January 2007 to December 2019 were retrospectively analyzed. The incidence, characteristics, and risk factors of complications (infection, hemorrhage, and chemotherapy-related adverse reactions (CRAR)) requiring hospitalization during induction chemotherapy in these children were explored. (1) A total of 108 patients with HR-NB were included in the final analysis. The overall infection rate was 92.6% (100/108), with the highest incidence of 71.3% observed during the first cycle. FN, bacterial infection, as well as fungal infection were common infectious complications in children with HR-NB during induction chemotherapy. (2) The overall hemorrhage rate was 24.1% (26/108), with the highest incidence of 14.8% also observed in the first cycle. Among the children with hemorrhage, there were 72% with bone marrow involved, while 65.0% of them had a high vanillylmandelic acid (VMA) value. And children with hemorrhage also exhibited neuron-specific enolase (NSE) ≥ 200 µg/L in 88.5% of cases and lactic dehydrogenase (LDH) ≥ 1000U/L in 73.1% of cases. (3) The incidence of CRAR rate was 100%, and 99.1% (107/108) patients experienced myelosuppression. The incidence of myelosuppression peaked in the third cycle, reaching up to 85.2%. Most children suffered severe myelosuppression existed with bone marrow metastases (76.3%), abnormal VMA (67.5%), and LDH ≥ 1000 U/L (60%). (4) Non-myelosuppressive adverse effects were observed in 75.9% children (82/108), with the highest incidence occurring in the third cycle at 42.6%. (5) Patients who experienced three types of complications had a lower median survival time (MST) of 54.4 months, a 3-year event-free survival (EFS) rate of (44.2 ± 10.7)%, and a 3-year overall survival (OS) rate of (75.8 ± 8.6)%, in comparison to those with only one or two complications, who had a higher MST of 59.5 months, a 3-year EFS rate of (73.5 ± 5.2)% (X2 = 10.457, P = 0.001), and a 3-year OS rate of (84.8 ± 4.1)% (X2 = 10.511, P = 0.001). CONCLUSION: The presence of bone marrow involved and increased VMA were high-risk factors for infection, while NSE ≥ 200 µg/L and LDH ≥ 1000 U/L were high-risk factors for hemorrhage. For those children who had experienced severe myelosuppression, the presence of bone marrow metastases, increased VMA, and LDH ≥ 1000 U/L were their risk factors. The presence of bone involvement was a high-risk factor for children to have non-myelosuppressive adverse effects. Complications that arise during induction chemotherapy could negatively impact the children's prognosis and overall quality of life. WHAT IS KNOWN: ⢠The high-risk neuroblastoma (HR-NB) had a worse prognosis; there was a general international preference for high-intensity chemotherapeutic regimens in the induction phase to these children. WHAT IS NEW: ⢠We analyzed the incidence and risk factors of complications during induction chemotherapy in children with HR-NB and tried to help clinicians predict such complications and adopt optimized therapeutic strategy.

Hypothyroidism as a long-term complication in cancer survivors has been an issue, but few studies have focused on changes in thyroid hormone levels during chemotherapy for leukaemia. This retrospective study was conducted to assess the characteristics of children with acute lymphoblastic leukaemia (ALL) and hypothyroidism during induction chemotherapy and to investigate the prognostic value of hypothyroidism in ALL. Patients with a detailed thyroid hormone profile at ALL diagnosis were enrolled. Hypothyroidism was defined as low serum levels of free tetraiodothyronine (FT4) and/or free triiodothyronine (FT3). The Kaplan-Meier method was used to create survival curves, and multivariate Cox regression analysis was used to screen prognostic factors associated with progression-free survival (PFS) and overall survival (OS). There were 276 children eligible for the study, and 184 patients (66.67%) were diagnosed with hypothyroidism, including 90 cases (48.91%) with functional central hypothyroidism and 82 cases (44.57%) with low T3 syndrome. Hypothyroidism was correlated with the dosages of L-Asparaginase (L-Asp) (P = .004) and glucocorticoids (P = .010), central nervous system (CNS) status (P = .012), number of severe infections (grade 3, 4 or 5) (P = .026) and serum albumin level (P = .032). Hypothyroidism was an independent prognostic factor for PFS in ALL children (P = .024, 95% CI: 1.1-4.1). We conclude that hypothyroidism is commonly present in ALL children during induction remission, which is related to chemotherapy drugs and severe infections. Hypothyroidism was a predictor of poor prognosis in childhood ALL.

Although initial central nervous system (CNS) involvement is rarely detected in childhood acute lymphoblastic leukemia (ALL), risk-adapted CNS-directed therapy is essential for all patients. Treatment intensity depends on the initial CNS status. In the AIEOP-BFM ALL 2009 trial, patients with cytomorphologic detection of leukemic blasts in initial cerebrospinal fluid were classified as CNS2 or CNS3 and received five intrathecal doses of methotrexate (MTX) in induction therapy compared to patients with CNS1 status (no blasts detected) who received three doses. The impact of additional intrathecal (IT) MTX on systemic toxicity in induction therapy is unknown. Between June 1st 2010 and February 28th 2017, a total of 6,136 ALL patients aged 1-17 years were enrolled onto the AIEOP-BFM ALL 2009 trial. The effect of three versus five doses of IT MTX during induction therapy on the incidence of severe infectious complications was analyzed. Among 4,706 patients treated with three IT MTX doses, 77 (1.6%) had a life-threatening infection during induction as compared to 59 of 1,350 (4.4%) patients treated with five doses (P<0.001; Odds Ratio 2.86 [95% Confidence Interval 1.99-4.13]). In a multivariate regression model, treatment with additional IT MTX proved to be the strongest risk factor for life-threatening infections (Odds Ratio 2.85 [1.96-4.14]). Fatal infections occurred in 16 (0.3%) and 38 (1.6%) patients treated with three or five IT MTX doses, respectively (P<0.001). As the relevance of additional intrathecal MTX in induction for relapse prevention in CNS2 patients is unclear, doses of intrathecal therapy have been reduced for these patients.

OBJECTIVES: Anti-melanoma differentiation-associated protein-5 (MDA5) autoantibodies (Abs) are associated with rapidly progressive interstitial lung disease (RP-ILD) in dermatomyositis (DM). Because the addition of plasma exchange (PE) and rituximab (RTX) to triple therapy is inadequate in severe cases, we treat such cases with intensive induction therapy (IIT) combining all these options with tofacitinib (TOF). In this study, we investigated the poor prognostic factors and the efficacy and safety of IIT. METHODS: Thirty-three patients diagnosed with anti-MDA5 Ab-positive DM in our institution between 2014 and 2021 were included. The clinical characteristics of poor prognosis were retrospectively analysed using principal component analysis (PCA), and the outcomes of IIT were analysed in terms of survival, assessed using the Kaplan-Meier test, and adverse events. RESULTS: Although triple therapy with RTX, PE, or intravenous immunoglobulin was administered before the introduction of IIT, eight of 12 RP-ILD cases with a ferritin level >400 ng/mL (mean, 2,342) died within a median of 2.5 months. PCA revealed distinct clusters for prognosis, and age and serum ferritin were leading predictors of the prognosis. IIT, consisting of combinations of triple therapy with higher doses of methylprednisolone, PE, RTX, and TOF, was applied to eight patients (mean ferritin, 3,558). Although two patients died even with these regimens, a significant improvement in survival was documented. Several IIT-related adverse events were observed, including viral and fungal infections and cytopenia. CONCLUSIONS: IIT significantly improved the survival of patients with severe anti-MDA5 Ab-positive RP-ILD. Although infections are noted, their benefits outweigh the risks in younger patients with high serum ferritin levels.

As a mainstay of treatment for acute lymphoblastic leukemia (ALL), vincristine's side effect profile is well known. Parallel administration of the antifungal fluconazole has been shown to interfere with the metabolism of vincristine, potentially resulting in increased side effects. We conducted a retrospective chart review to determine whether concomitant administration of vincristine and fluconazole during pediatric ALL induction therapy impacted the frequency of vincristine side effects, namely, hyponatremia and peripheral neuropathy. We also evaluated whether the incidence of opportunistic fungal infections was impacted by fluconazole prophylaxis. Medical charts of all pediatric ALL patients treated with induction chemotherapy at Children's Hospital and Medical Center in Omaha, NE, from 2013 to 2021 were retrospectively reviewed. Fluconazole prophylaxis did not significantly impact the rate of fungal infections. We found no correlation between fluconazole use and increased incidence of hyponatremia or peripheral neuropathy, which supports the safety of fungal prophylaxis with fluconazole during pediatric ALL induction therapy.

OBJECTIVE: The purpose of this study was to compare the clinical outcomes and toxicities between induction chemotherapy (IC) + chemo-radiotherapy (CRT) and CRT alone in patients with locally advanced esophageal squamous cell carcinoma (ESCC), to explore the appropriate thoracic radiotherapy (TRT) timing after IC and to identify prognostic factors. METHODS: 450 ESCC patients were included from September 2011 to December 2020, 238 of whom received IC/CRT. Propensity score matching was performed to balance potential confounders between the two groups. Multivariate Cox regression analysis was used to identify the independent prognostic factors. RESULTS: Patients who received IC/CRT experienced improved overall survival (OS) (38.5 vs. 28.8 months) and progression-free survival (PFS) (41.0 vs. 22.0 months) before matching, with similar results after matching. In the IC/CRT group, early TRT had more favorable survival than late TRT both matching before and after. In subgroup analysis, early TRT combination concurrent chemotherapy had better OS and PFS than late TRT combination concurrent chemotherapy. In addition, early TRT had better survival benefits regardless of the N stage. Notably, the IC/CRT group and early TRT group had manageable toxicities reaction compared with CRT alone group and the late TRT group. The nomogram was developed to predict the OS and PFS based on multivariate analysis results. The C-index was 0.743 and 0.722, respectively. CONCLUSION: IC/CRT and early TRT could yield satisfactory clinical outcomes and controllable toxicities in locally advanced ESCC. The IC plus early concurrent CRT might be a promising treatment strategy for improving further survival in ESCC.

BACKGROUND: The objective of this study was to evaluate the efficacy and safety of induction chemotherapy (ICT), GOFL (gemcitabine, oxaliplatin plus fluorouracil (5-FU)/leucovorin) versus modified FOLFIRINOX (irinotecan, oxaliplatin plus 5-FU/leucovorin), followed by concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic adenocarcinoma (LAPC). METHODS: Chemo-naive patients with measurable LAPC were eligible and randomly assigned to receive biweekly ICT with either mFOLFIRINOX or GOFL for 3 months. Patients without systemic progression would have 5-FU- or gemcitabine-based CCRT (5040 cGy/28 fractions) and were then subjected to surgery or continuation of chemotherapy until treatment failure. The primary endpoint was 9-month progression-free survival (PFS) rate. RESULTS: Between July 2013 and January 2019, 55 patients were enrolled. After ICT, 21 (77.8%) of 27 patients who received mFOLFIRINOX and 17 (60.7%) of 28 patients who received GOFL completed CCRT. Of them, one and five had per-protocol R0/R1 resection. On intent-to-treat analysis, the 9-month PFS rate, median PFS and overall survival in mFOLFIRINOX and GOFL arms were 30.5% versus 35.9%, 6.6 (95% confidence interval: 5.9-12.5) versus 7.6 months (3.9-12.3) and 19.6 (13.4-22.9) versus 17.9 months (13.4-23.9), respectively. Grade 3-4 neutropenia and diarrhoea during induction mFOLFIRINOX and GOFL were 37.0% versus 21.4% and 14.8% versus 3.6%, respectively. CONCLUSION: Induction GOFL and mFOLFIRINOX followed by CCRT provided similar clinical outcomes in LAPC patients. GOV IDENTIFIER: NCT01867892.

BACKGROUND: Platinum-based concurrent chemoradiotherapy is the standard of care for patients with locoregionally advanced nasopharyngeal carcinoma. Additional gemcitabine and cisplatin induction chemotherapy has shown promising efficacy in phase 2 trials. METHODS: In a parallel-group, multicenter, randomized, controlled, phase 3 trial, we compared gemcitabine and cisplatin as induction chemotherapy plus concurrent chemoradiotherapy with concurrent chemoradiotherapy alone. Patients with locoregionally advanced nasopharyngeal carcinoma were randomly assigned in a 1:1 ratio to receive gemcitabine (at a dose of 1 g per square meter of body-surface area on days 1 and 8) plus cisplatin (80 mg per square meter on day 1), administered every 3 weeks for three cycles, plus chemoradiotherapy (concurrent cisplatin at a dose of 100 mg per square meter every 3 weeks for three cycles plus intensity-modulated radiotherapy) or chemoradiotherapy alone. The primary end point was recurrence-free survival (i.e., freedom from disease recurrence [distant metastasis or locoregional recurrence] or death from any cause) in the intention-to-treat population. Secondary end points included overall survival, treatment adherence, and safety. RESULTS: A total of 480 patients were included in the trial (242 patients in the induction chemotherapy group and 238 in the standard-therapy group). At a median follow-up of 42.7 months, the 3-year recurrence-free survival was 85.3% in the induction chemotherapy group and 76.5% in the standard-therapy group (stratified hazard ratio for recurrence or death, 0.51; 95% confidence interval [CI], 0.34 to 0.77; P = 0.001). Overall survival at 3 years was 94.6% and 90.3%, respectively (stratified hazard ratio for death, 0.43; 95% CI, 0.24 to 0.77). A total of 96.7% of the patients completed three cycles of induction chemotherapy. The incidence of acute adverse events of grade 3 or 4 was 75.7% in the induction chemotherapy group and 55.7% in the standard-therapy group, with a higher incidence of neutropenia, thrombocytopenia, anemia, nausea, and vomiting in the induction chemotherapy group. The incidence of grade 3 or 4 late toxic effects was 9.2% in the induction chemotherapy group and 11.4% in the standard-therapy group. CONCLUSIONS: Induction chemotherapy added to chemoradiotherapy significantly improved recurrence-free survival and overall survival, as compared with chemoradiotherapy alone, among patients with locoregionally advanced nasopharyngeal carcinoma.

Patients undergoing treatment of acute lymphoblastic leukemia (ALL) are at risk for thrombosis, caused in part by the use of l-asparaginase (L-ASP). Antithrombin (AT) replacement has been suggested to prevent venous thromboembolism (VTE) and thus may increase exposure to ASP. We report herein the results of the prophylactic replacement strategy in the pediatrics-inspired prospective GRAALL-2005 study. Between 2006 and 2014, 784 adult patients with newly diagnosed Philadelphia- ALL were included. The incidence rate of VTE was 16%, with 69% of cases occurring during induction therapy. Most patients received AT supplementation (87%). After excluding patients who did not receive L-ASP or who developed thrombosis before L-ASP, AT supplementation did not have a significant impact on VTE. Administration of fibrinogen concentrates was associated with an increased risk of VTE, whereas transfusion of fresh frozen plasma had no effect. Heparin prophylaxis was associated with an increased risk of VTE. Prophylactic measures were not associated with an increased risk of grade 3 to 4 bleeding complications. The rate of VTE recurrence after L-ASP reintroduction was 3% (1 of 34). In ALL patients receiving L-ASP therapy, the use of fibrinogen concentrates may increase the risk of thrombosis and should be restricted to rare patients with hypofibrinogenemia-induced hemorrhage. VTE developed despite extensive AT supplementation, which suggests the need for additional prophylactic measures. Although this large descriptive study was not powered to demonstrate the efficacy of these prophylactic measures, it provides important insight to guide future trial design. This trial was registered at www.clinicaltrials.gov as #NCT00327678.

PURPOSE: Concurrent chemoradiotherapy (CCRT) is a standard treatment choice for locally advanced hypopharyngeal carcinoma. The aim of this study was to investigate whether induction chemotherapy (IC) followed by CCRT is superior to CCRT alone to treat locally advanced hypopharyngeal carcinoma. METHODS AND MATERIALS: Patients (n = 142) were randomized to receive two cycles of paclitaxel/cisplatin/5-fluorouracil (TPF) IC followed by CCRT or CCRT alone. The primary end point was overall survival (OS). The secondary end points included the larynx-preservation rate, progression-free survival (PFS), distant metastasis-free survival (DMFS), and toxicities. RESULTS: Ultimately, 113 of the 142 patients were analyzed. With a median follow-up of 45.6 months (interquartile range 26.8-57.8 months), the 3-year OS was 53.1% in the IC + CCRT group compared with 54.8% in the CCRT group (hazard ratio, 1.004; 95% confidence interval, 0.573-1.761; P = 0.988). There were no statistically significant differences in PFS, DMFS, and the larynx-preservation rate between the two groups. The incidence of grade 3-4 hematological toxicity was much higher in the IC+ CCRT group than in the CCRT group (54.7% vs. 10%, P < 0.001). CONCLUSIONS: Adding induction TPF to CCRT did not improve survival and the larynx-preservation rate in locally advanced hypopharyngeal cancer, but caused a higher incidence of acute hematological toxicities.

BACKGROUND: The anti-CD20 rituximab is often used in the treatment of children with steroid-resistant nephrotic syndrome or EBV-induced post-transplant lymphoproliferative disorder. This single-center series reports the use of rituximab as induction therapy in pediatric kidney transplantation. METHODS: Four children who received rituximab as induction therapy for kidney transplantation since 2016 were retrospectively analyzed. Clinical and laboratory data were extracted from medical records. RESULTS: The patients (2 boys and 2 girls) were aged from 6.1 to 11.9 years and were treated with rituximab on the day of the transplantation procedure; all the transplants came from deceased donors. In all patients, rituximab was used because of positive EBV viral loads before kidney transplantation. Viral loads remained undetectable for the first 6 months after the transplantation procedure and remained below the 4.5 log threshold thereafter. After a median follow-up of 2.3 years, none of the patients displayed rejection or de novo donor-specific antibodies; the glomerular filtration rate remained above 70 ml/min/1.73 m2 . No post-transplant lymphoproliferative disorder was observed. CONCLUSION: The results suggest that rituximab can be used as induction therapy to prevent EBV replication and its complications in case of positive viral load prior to kidney transplantation.

Chylothorax is an unusual complication of childhood cancer. It causes to additional morbidity and mortality during management. It should be kept in mind that chylothorax may occur due to mass shrinkage during treatment in patients with mediastinal mass and ductus thoracicus invasion at the initial diagnosis and necessary measures should be taken. This case was presented because of the rarity in pediatric oncology practice.

PURPOSE: Nasopharyngeal carcinoma (NPC) is a malignant tumor endangering human health. Gemcitabine or cisplatin chemotherapy has been regarded as effective treatment for patients with locoregionally advanced NPC. However, the effect of gemcitabine plus cisplatin concurrent chemoradiotherapy (CCRT) remained controversial among the studies. Therefore, we conducted this meta-analysis to assess the efficacy and safety of induction chemotherapy by gemcitabine and cisplatin (GP regimen) in patients with locoregionally advanced NPC. METHODS: A systematic literature search was performed using PubMed, Web of Science, and Embase to evaluate the survival benefit and toxicity profiles of patients with locoregionally advanced NPC who were treated with CCRT. A random-effects model or a fixed-effects model was used to pool the data according to the heterogeneity among the included studies. RESULTS: A total of five studies with 1286 patients met the inclusion criteria and were included in this meta-analysis. Pooled estimate showed that GP regimen was associated with significant improvements in OS (HR = 0.57, 95% CI 0.45, 0.73; P < 0.001), DFS (HR = 0.56, 95% CI 0.47, 0.66; P < 0.001), and DRFS (HR = 0.51, 95% CI 0.36, 0.73; P < 0.001), but not in LRFS (HR = 0.54, 95% CI 0.25, 1.19; P = 0.126) and ORR (RR = 1.30, 95% CI 0.54, 3.09; P = 0.556). Moreover, the incidence of adverse events of all grades (RR = 1.15, 95%CI 0.11, 1.38; P = 0.063) or grade 3-4 (RR = 0.96, 95%CI 0.57, 1.29; P = 0.385), was comparable between GP regimen and control treatments. CONCLUSION: Our meta-analysis indicated that the patients with locoregionally advanced NPC could benefit from the regimen of gemcitabine plus cisplatin induction chemotherapy.

We present a 65-year-old woman who developed a diffuse pruritic papular eruption after receiving induction chemotherapy with daunorubicin and cytarabine for newly diagnosed acute myelomonocytic leukemia. The rash improved clinically with triamcinolone treatment and chemotherapy was allowed to continue. This case adds to the growing literature of transient acantholytic dermatosis development in the setting of anti-cancer therapy and emphasizes the importance of clinicopathologic correlation in cutaneous eruptions in cancer patients.
