RESUMO
OBJECTIVE: Diarrhea is often observed as an immune-related adverse event. In this study, we conducted a retrospective review of the severity of diarrhea, its treatment and the endoscopic findings in patients developing diarrhea as an immune-related adverse event. METHODS: From August 2015 to June 2019, a total of 369 patients received treatment with immune checkpoint inhibitors at our hospital. For this study, development of grade 2 or more diarrhea in these patients was defined as an immune-related adverse event. We analyzed the histopathological severity of the bowel lesions according to the Nancy histological index for ulcerative colitis. RESULTS: Of the 369 patients, 27 (7.3%) developed diarrhea as an immune-related adverse event. Of these 27 patients, 18 received steroid treatment. Colonoscopy was performed in 17 patients and culture of the feces in 18. The tests revealed evidence of bacterial colitis (Aeromonas hydrophila) in two patients. The Nancy histological index was 4, 3, 2, 1 and 0 in two, three, two, two and seven patients, respectively. No findings on colonoscopy were observed in 7 of the 17 patients (41%) who underwent colonoscopy, and most of these patients recovered without steroid treatment. Patients with lower values of the Nancy histological index tended to show better responses to steroid treatment. CONCLUSIONS: To avoid unnecessary steroid administration, colonoscopic evaluation is essential in patients receiving treatment with immune checkpoint inhibitors who present with diarrhea as an immune-related adverse event. In addition, the endoscopic findings could be useful to predict the response to steroid treatment.

OBJECTIVE: Cisplatin is administered in combination with massive hydration to avoid renal toxicity, making its administration difficult in an outpatient setting. Although a short hydration protocol for cisplatin has been recently developed, its safety is not fully understood. METHODS: Consecutive patients with lung or other cancer and an Eastern Cooperative Oncology Group performance status of 0-2 who were receiving chemotherapy containing cisplatin at a dose of ≥60 mg/m(2) in a single administration were evaluated. Seventy-four patients were treated with a short hydration protocol consisting of 1750-2250 ml of hydration with mannitol and magnesium supplementation over a period of 3.75-4.75 h on Day 1. Sixty-nine patients were treated with a conventional hydration protocol consisting of 2100-2600 ml of hydration over 6.5-7.5 h on Day 1 with pre- and post-hydration on Days 0, 2 and 3. Toxicity was then compared between the two groups. RESULTS: An elevated serum creatinine level ≥grade 1 was significantly less frequent in the group receiving the short hydration protocol than in the group receiving conventional hydration. Other toxicities were similar between the two groups. Consequently, the completion rate for the planned treatment in the short hydration group (73.0%, 54/74) was significantly higher than that in the conventional hydration group (53.6%, 37/69). CONCLUSIONS: Short hydration is safe, making cisplatin-containing chemotherapy easier to perform.

OBJECTIVE: Extravasation, the accidental leakage of an anticancer agent from a vessel into the surrounding tissues, can lead to irreversible local injuries and severe disability. Despite its considerable clinical importance, evidence-based information on extravasation in chemotherapy is lacking. This study characterized the clinical features of extravasation and identified issues to be resolved in current cancer chemotherapy performed in outpatient settings. METHODS: We retrospectively reviewed the medical charts of patients who received chemotherapy and sustained extravasation in our Outpatient Chemotherapy Clinic from April 2007 to August 2012. Chemotherapy administration and extravasation management procedures were standardized using the in-house chemotherapy guideline. RESULTS: Among 43 557 patients who received chemotherapy, 35 (0.08%) experienced extravasation. The duration between the start of infusion and extravasation was >2 h in 28 (80.0%) patients. The severity of extravasation was Grades 1, 2 and 3 in 28, 2 and 5 patients, respectively-three of whom were associated with port trouble. The contributing factor for extravasation was walking in 11 (31.4%) patients. All extravasations were cured without surgical intervention by management according to our guidelines. CONCLUSIONS: The incidence of extravasation is as low as 0.08%, using our in-house chemotherapy guideline. Extravasation from implanted ports tends to be severe.

Severe drug-induced lung injury (DLI) has been reported to be associated with sequential administration of osimertinib, a third-generation tyrosine kinase inhibitor, following a programmed cell death ligand 1 (PD-L1) inhibitor. However, the relationship of sequential treatment with an anti-epidermal growth factor receptor (EGFR) antibody and PD-1 inhibitor with the risk of DLI remains to be elucidated. The present study conducted a retrospective review of the medical records of a total of 179 patients with head and neck cancer who had received treatment with cetuximab and/or a PD-1 inhibitor (nivolumab or pembrolizumab) at Chiba University Hospital (Chiba, Japan) between September 2014 and December 2020. The incidence of pneumonia and the clinical background characteristics of the patients were analyzed. The patients were classified into subgroups for analysis of the outcomes in this study: Patients who had received sequential, but not concurrent, cetuximab and PD-1 inhibitor treatment (Group C+P; n=43); patients who had received cetuximab-containing chemotherapy, but not a PD-1 inhibitor (Group C; n=101); and patients who had received PD-1 inhibitor-containing chemotherapy, but not cetuximab (Group P; n=35). The rates of DLI in the three groups were: Group C+P, 18.6%; Group C, 7.9%; and Group P, 11.4%. Prior use of ICI was not associated with any increase in the risk of DLI. DLI is seen frequently in patients receiving sequential PD-1 inhibitor and anti-EGFR antibody therapy.
RESUMO
BACKGROUND: Nelarabine is an antineoplastic purine analog used for the treatment of refractory or relapsed T-cell acute lymphoblastic leukemia (T-ALL). The most prominent side effect of nelarabine are neurotoxicity and hematologic disorder, which are considered dose-limiting factors. Although clinical studies have reported myopathy due to nelarabine, actual detailed outcomes were not well-known initial approval. The incidence of nelarabine induced rhabdomyolysis has been reported at 2% in study in children. Cases of rhabdomyolysis have been reported in adults from medical facilities in the United Sates with renal dysfunction or severe muscle symptoms after administration of multiple courses of nelarabine. In this report, we discuss a case of rhabdomyolysis diagnosed after a single course of nelarabine. In this case, creatine kinase (CK) level was elevated in grade 4, without renal dysfunction and severe muscle symptoms. CASE PRESENTATION: A 46-year-old man from Japan was diagnosed with T-ALL and received a hematopoietic stem cell transplantation in first remission. However, the disease relapsed 6 months after transplantation. Nelarabine was selected as the next-line chemotherapeutic agent. The patient received 1500 mg/m2 of nelarabine on day 1 followed by a dose on days 3 and 5. CK levels, which were baseline before treatment, increased to grade 4 (18,620 IU/L) on the 8th day of treatment. He was diagnosed as rhabdomyolysis due to nelarabine with little possibility of other factors. He complained only of mild pain in his upper extremities and no other symptoms were noticed. The patient was managed with hydration. The pain lasted approximately 7 days, but there were no sequelae secondary to the rhabdomyolysis. Because of the elevation of CK in grade 4, we avoided re-administration. CONCLUSION: In the patient administrated nelarabine, CK level was elevated in grade 4, without other symptoms of rhabdomyolysis. The results suggest that CK may be elevated at the onset of rhabdomyolysis caused by nelarabine, even in the absence of other symptoms. Therefore, it was suggested that monitoring CK during nelarabine administration is important for detecting rhabdomyolysis before it becomes severe. We consider that CK should be monitored even in absence of symptoms.
RESUMO
Clinical trials have not fully demonstrated the efficacy and safety of radiotherapy plus cetuximab for locally advanced squamous cell head and neck cancer (LA-SCCHN) in patients with cisplatin-ineligible renal dysfunction. Patients who received radiotherapy plus cetuximab for LA-SCCHN at Chiba University Hospital (Chiba, Japan) between July 2013 and October 2018 were retrospectively reviewed. Background characteristics and locoregional control and overall survival rates were compared between patients with and without renal dysfunction. Survival was examined using Kaplan-Meier analysis and an adjusted Cox proportional hazards model. Kaplan-Meier analysis demonstrated that overall survival was shorter in patients with creatinine clearance of <45 ml/min (P=0.041; log-rank test). However, there was no difference in the locoregional control rate (P=0.477; log-rank test). Adjusted Cox analysis revealed that the risk of death was increased by 2.52-fold (hazard ratio, 2.52; 95% confidence interval, 1.01-6.30; P=0.048) if creatinine clearance was <45 ml/min. Moderate to severe renal dysfunction did not affect the locoregional control rate in patients with LA-SCCHN treated with radiotherapy plus cetuximab but was an adverse prognostic factor.
RESUMO
BACKGROUND: The blood concentration of cyclosporine (CyA) is frequently elevated following the transfusion of red blood cell concentrate (RCC) to patients after allogeneic hematopoietic stem cell transplantation (HSCT). The aim of this retrospective study was to identify the variable factors affecting changes in the blood concentration of CyA before and after transfusion of RCC. METHODS: We enrolled 105 patients (age, 5-66 years) who received both CyA and transfusion after HSCT. The ratio of the measurement after transfusion to the measurement before transfusion was calculated for the hematocrit and blood concentration/dose ratio of CyA (termed the HCT ratio and the CyA ratio, respectively). RESULTS: The blood concentration/dose ratio of CyA was increased after transfusion compared with before transfusion (P < 0.001). The HCT ratio was significantly correlated with the CyA ratio (P = 0.23, P < 0.001). The HCT ratio, concomitant medication that could elevate CyA concentration after RCC transfusion, and difference in the alkaline phosphatase level between before and after transfusion (ΔALP) were explanatory variables associated with the variation in the CyA ratio. There was no correlation between the CyA concentration after transfusion and the change in the estimated glomerular filtration rate. CONCLUSIONS: A change in the blood concentration/dose ratio of CyA was found to be associated with a change in the HCT, concomitant medication that could elevate CyA concentration after RCC transfusion, and ALP levels. If the HCT level rises significantly after RCC transfusion, clinicians and pharmacists should pay attention to changes in the blood CyA concentration.
RESUMO
A 69-year-old woman was diagnosed as having non-small cell lung cancer (adenocarcinoma, T1aN3M1b). She had no history of surgery or abdominal trauma. She was treated with ramucirumab (10 mg/kg) plus docetaxel (60 mg/m2) intravenously (RAM + DTX) every 3 weeks. Although an enhanced CT examination showed a partial tumor response after eight courses of RAM + DTX, she gradually began to experience abdominal fullness with severe peripheral pitching edema. Her body weight increased by 18 kg in 2 months and RAM + DTX chemotherapy was discontinued. An enhanced CT examination showed a large amount of ascites and pleural effusion, with no obstructions of the central vein or lymphatic ducts. The ascites were white and milky in appearance and contained 527 mg/dL of triglyceride. In addition, her pleural effusion was also white and milky in appearance. No further increases in ascites and pleural effusion were observed thereafter. Four months after her last RAM + DTX chemotherapy, she continued to exhibit a partial response and no increases in ascites or pleural effusion were present. The chylous effusion might have been caused by the RAM + DTX chemotherapy.
RESUMO
We herein describe a 67-year-old man with advanced adenocarcinoma of the lung who developed an alveolar hemorrhage (AH) associated with pemetrexed. He received four courses of pemetrexed therapy with carboplatin and seven courses of pemetrexed maintenance therapy. One week after the last pemetrexed administration, the patient developed hemoptysis with deteriorating dyspnea and anemia. Chest images showed diffuse ground-glass attenuation. The diagnosis of AH was based on findings of bloody bronchoalveolar lavage (BAL) fluid, hemosiderin-laden macrophages in the BAL fluid, and a transbronchial lung biopsy sample. This report is the first to describe AH associated with pemetrexed.
