We report here a rare case of atypical posterior reversible encephalopathy syndrome (PRES) due to oral tyrosine kinase inhibitor cabozantinib. No case reports of such have been found in our literature search. The patient, a 70-year-old female with metastatic renal cell cancer on oral tyrosine kinase inhibitor cabozantinib, was brought into the emergency room because of confusion and seizures, found to have elevated blood pressure and atypical MRI findings consistent with PRES due to cabozantinib.
Herein, we present a very rare case of enteropathy-associated T-cell lymphoma (EATL) type 2 with pulmonary metastasis which was biopsy-proven. This is a very rare type of lymphoma, and no case reports or studies of enteropathy-associated T-cell lymphoma with pulmonary metastatic disease were found in the literature review.This 64-year-old male, who presented with an acute abdomen, was found to have a perforation. Subsequent pathology of the resected specimen showed neoplastic cells consistent with EATL type 2. Four months post-diagnosis, the patient developed shortness of breath. Positron emission tomography (PET) scan revealed multiple metabolically active pulmonary nodules. A biopsy of the nodules was consistent with metastatic EATL type 2 involving the lungs.
We present here a rare and unusual presentation of angioimmunoblastic T-cell lymphoma with non-necrotizing granuloma of bone marrow. We did not find any case reports of such case in our literature search. A 77-year-old man presented with shortness of breath, generalized weakness, fatigue and weight loss. Laboratory data revealed elevated white count, low platelets and anemia. Imaging studies revealed generalized lymphadenopathy. A bone marrow biopsy showed hypercellular marrow with non-caseating granuloma which was nondiagnostic and lymph node biopsy showed angioimmunoblastic T-cell lymphoma.
Bone marrow metastasis with profound pancytopenia is an extremely uncommon presentation of breast cancer. Advanced breast cancer can frequently metastasize to bone marrow, but bone marrow failure is not typically seen. Very limited data exist regarding the appropriate management of patients with metastatic breast cancer with profound pancytopenia. Our patient’s initial presentation of anemia and thrombocytopenia was a diagnostic dilemma, later confirmed as metastatic breast cancer on bone marrow biopsy. After diagnosis, treatment was another challenge as there are no predefined treatment guidelines for these patients. After the initial hormonal therapy failed, our patient showed a good clinical response to chemotherapy and her platelet count improved to baseline. This dramatic response to chemotherapy is rare. Therefore, this case represents a rare instance of a diagnostic and therapeutic dilemma with unusual clinical response to chemotherapy.
e19265 Background: ICIs are used for a variety of malignancies and have shown to improve survival, but they are associated with IRAEs. We aim to identify the frequency and severity of new IRAEs and flares of preexisting autoimmune (AI) disorders excluding thyroid disorders in cancer patients treated with ICIs at our institution. Methods: We conducted a retrospective chart review analysis of all cancer patients who received ICIs: nivolumab, pembrolizumab, atezolizumab and durvalumab at the Northern Light Cancer Institute from June 2015 to March 2019. We excluded patients who received ipilimumab. We then studied those who developed IRAEs. Results: Out of 465 who received ICIs, 115(24.7%) developed IRAEs. 83 out of 298 (27.9%) nivolumab recipients, 20/121 (15.7%) pembrolizumab recipients, 5/26 (19.2%) atezolizumab and 7/20 (35%) durvalumab recipients developed IRAEs. Some patients had multiple toxicities. Median age at cancer diagnosis was 66 years, evenly split among males and females. Majority (63%) were treated for Lung cancer, followed by melanoma (20%) and genitourinary cancers (12%). Summary of new IRAEs are as noted in the table below. In patients with new IRAEs treatment was held in 29(6%) for a median duration of 7.2 wks. Upon rechallenge with the same ICI in 27 patients, 20(74%) tolerated and 7 did not leading to permanent discontinuation. Majority were treated with steroids and some required immunomodulators. Interestingly 39(8%) patients with underlying AI condition received ICIs. Of these 11(28.2%) developed flares, resulting in permanent discontinuation of drug in 4. The majority tolerated the treatment well. Treatment was permanently discontinued in 70(15%), 26(6%) required hospital admission for IRAEs. Pneumonitis was the most common toxicity necessitating treatment discontinuation and hospital stay. Conclusions: In real world setting the frequency and severity of IRAEs was more than the reported literature data, leading to higher rates of permanent discontinuation of treatment. [Table: see text]
e18682 Background: Reducing ED visits in patients with cancer is cost saving and is particularly relevant during the COVID pandemic. Methods: We analyzed the number of ED visits occurred in our breast cancer population between July 1 2019 and August 31 2020 including demographics, stage distribution, treatment type within the month of ED visit, reason, time of the day, day of the week the visit occurred. Results: A total of 101 patients had 162 visits. 38 (38%) had more than 1 ED visit. Majority (36%) had stage 4 disease at the time of ED visit. The top 5 reasons for ED visits were fall and injury (N=30), GI (N=24), cardiac (N=17), respiratory symptoms (N=14) and cancer related pain (N=11). The median age in patients with ED visit due to fall injury/pain was 75 and non-fall injury/pain was 55 years. The most common reasons for chemotherapy induced ED visits were GI related (N=8) and Neutropenic fever (N=7). Cyclophosphamide/doxorubicin was the common regimen associated with neutropenic fever. A total of 72 (44%) visits resulted in hospital admissions. Most common symptom categories requiring hospital admissions were cardiac (82.3%), sepsis/cellulitis (81.8%), respiratory (64%), cancer related pain (54.5%) and GI (50%). Most were on endocrine therapy at the time of their visit (N= 59) and 31 were on no treatment at all. Falls were unrelated to disease or treatment and occurred in patients above age 70. Visits occurred during working hours from 6AM to 5PM, with peak incidence on Mondays and Fridays. Conclusions: Reducing ED visit in cancer patients is a worthwhile endeavor particularly in the context of the COVID pandemic. The main reason for ED visits were falls and injuries that were unrelated to disease or treatment in breast cancer patients. As a result, we are implementing systematic physical therapy assessment for our breast cancer population over age of 60 at our cancer center and call us first campaign, to get an opportunity to intervene prior to going to the ED as majority of the ED visits occurred during working hours.[Table: see text]
