The Support in Opioid Introduction Period for Outpatients with Cancer by Palliative Care Staffs

Introduction: Our palliative care staff began the support activity in opioid introduction for outpatients with cancer at Komaki City Hospital in March 2018, because it was difficult to make them understand about proper use of opioid analgesics and misinterpretation about abuse at the time of opioid introduction in outpatient settings. This study aimed to evaluate the effects of the activity (patient education on pain control, telephone follow up, and assessment of the symptom). Method: Outpatients with cancer receiving strong opioids for pain relief from January 2017 to March 2019 were eligible. We retrospectively investigated the difference of the variables between baseline and after the activity as follows; the ratios of prescribing immediate-release opioids, antiemetics, and laxatives when opioids were prescribed and side effects due to opioid analgesics appeared. Results: The study included 122 patients. The prescribing ratios of immediate-release opioids antiemetics and laxatives all increased from 90.7 to 98.5%, from 63.0 to 70.6%, and from 61.1 to 70.6%, respectively. The side effect incidence due to opioids with STAS-J 2 or more decreased from 12 (22.2%) to 9 (13.2%). Discussion: The activity could contribute to the provision of drug treatments and counselling needed for opioid therapy.

Administration of Corticosteroids Is Effective for Hyperactive Delirium Due to Intravascular Large B-cell Lymphoma: A Case Report

Introduction: Intravascular large B-cell lymphoma (IVLBCL) is a rare disease entity of non-Hodgkin lymphoma. Patients with IVLBCL frequently have neurological symptoms associated with cerebrovascular infarction or central nervous system involvement of malignant lymphoma. Case: A 67-year-old man consulted the Department of Hematology at our hospital because of fever of unknown origin, anemia and increased serum lactate dehydrogenase. Although IVLBCL was strongly suspected, no lymphoma cells were found by multiple bone marrow aspirations and skin biopsies. Two months later, he developed hyperactive delirium, which was difficult to manage using antipsychotic agents. Brain MRI revealed multiple hyper-intense infarct-like lesions on diffusion-weighted images. After assessment of bone marrow aspiration and skin biopsies, he was administered an enough dose of prednisolone to manage malignant lymphoma. Hyperactive delirium rapidly improved. Discussion: In patients with IVLBCL, corticosteroids may be useful to manage hyperactive delirium due to cerebrovascular infarction or central nervous system involvement of IVLBCL.

Efficacy and Safety of Subcutaneous Levetiracetam Injection for Terminally-ill Cancer Patients: A Case Report

Introduction: Antiepileptic drugs were occasionally administered to manage seizures in terminally-ill cancer patients. When enteral route is no longer feasible due to dysphagia or depressed level of consciousness, subcutaneous route could be an option. We reported three cases of terminally cancer patients who received subcutaneous levetiracetam (LEV) due to an inability to administer via intravenous route. Cases: The age of 3 cases was 83, 75, 82 years, respectively. In all cases, the prognosis prediction at the start of subcutaneous LEV was about 1 month. In all cases, the route of administration of LEV was changed from intravenous to subcutaneous. No exacerbation of convulsions, or injection site reaction was confirmed after subcutaneous LEV administration. Discussion: We believe that subcutaneous LEV administration may be one of the treatment options for seizures in patients with terminal cancer for whom intravenous administration of LEV is no longer feasible.

Adverse Effects of Oxygen Therapy for Dyspnea in Terminally Ill Cancer Patients: A Retrospective Single Center Analysis

Context: In addition to opioids, oxygen therapy is often administered to cancer patients suffering from dyspnea before death, but there are few reports of adverse effects of this treatment. Objectives: To clarify the frequency of adverse effects of oxygen therapy for hospitalized cancer patients before death. Methods: A retrospective study of all patients who died and were discharged from the palliative care unit in Komaki City Hospital from January 2016 to June 2018 was performed. Patients to whom oxygen therapy had already been administered at the time of admission were excluded in the study. Results: The study included 257 patients, with 195 (76%) in the oxygen therapy group (O2+). The cumulative rate of oxygen therapy was 36% seven days before death, 54% three days before death, and 76% a day before death. The adverse effects included a sense of restraint for 64 cases (31%), exacerbation of delirium for 27 cases (14%), nasal/oral hemorrhage for 25 cases (13%), dryness for 5 cases (3%), and deterioration of subjective symptoms for 4 cases (2%). Along with these effects, temporary interruption of oxygen therapy was observed in 76 cases (39%). Conclusion: Oxygen therapy was started in half of the cases within 3 days before death. The adverse events to occur frequently were feeling of restriction and exacerbation of delirium.

A Case of Emphysematous Cystitis with Lung Cancer at the End Stage

Introduction: We report on a patient with end-stage lung cancer who developed the relatively rare condition of emphysematous cystitis. Case: A 72-year-old man was diagnosed with carcinomatous meningitis while being treated for lung cancer and bone metastasis. Anticancer therapy was terminated, and he was transferred to our palliative care unit. During the transfer, he exhibited progressively impaired consciousness and bilateral leg paralysis. Imaging studies performed to assess his medical state revealed intrathecal nodes associated with carcinomatous meningitis and emphysema in the bladder wall. Emphysematous cystitis was diagnosed. The bladder was irrigated and drained, and antibiotic therapy was administered. Although the bladder wall emphysema resolved, the patient died of progression of carcinomatous meningitis on the 10th day after transfer. Discussion: The development of emphysematous cystitis is reported to be likely in patients with underlying diseases, such as malignant tumor, diabetes mellitus, and neurogenic bladder, as well as in those with a history of steroid use. Our patient also exhibited many risk factors, including a history of steroid use and bladder and rectal disturbance due to carcinomatous meningitis, in addition to cancer. In end-stage cancer patients, the risk of developing emphysematous cystitis is expected to be higher than in normal persons because they have often used steroids for malaise, anorexia, and other conditions, and exhibit metastasis to the central nervous system, drug-induced dysuria, and other complications. Caution should be exercised in end-stage cancer patients to recognize emphysematous cystitis, which can be life-threatening in some cases.

A Retrospective Observational Study to Explore Trajectories of Hematologic Data and Palliative Performance Scale Scores in the Last 12 Weeks among Patients with Terminal-stage Cancer

Objective: To explore the trajectories of hematologic data and palliative performance scale (PPS) scores among patients with terminal-stage cancer. Method: This was a retrospective observational study. We recruited all adult patients with solid cancer who received care from palliative care specialists and died in Komaki City Hospital between January and December 2016. Among these patients, we extracted hematologic data from the last 12 weeks and when 2 weeks passed since the last anti-cancer treatment, and PPS scores on the day of the hematologic tests. We calculated the means of weekly hematologic data and PPS scores, and explored their trajectories. Results: We recruited 204 patients (mean age, 70.9 years; women, 44.1%) and acquired 1157 hematological datasets. Albumin and C-reactive protein levels gradually decreased from 12 weeks and increased from 5 weeks, respectively, before death. White blood cell and lymphocyte counts respectively increased and decreased from 5 weeks. Creatinine and bilirubin levels rapidly increased from 3 weeks. Potassium levels increased from 1 week. PPS scores decreased from 4 weeks before death. Discussion: Deteriorations in nutrition or inflammatory status and white blood cell counts could antedate deterioration in PPS scores, and deterioration of visceral data and PPS scores could indicate prognosis on a weekly basis.
