Simultaneous Presentation of Multiple Myeloma and Lung Cancer: Case Report and Gene Bioinformatics Analysis.

ABSTRACT: Patients diagnosed with more than one cancer generally develop the individual tumors sequentially. There are a few cases of co-occurring multiple myeloma and lung cancer reported in the literature. Here, we report two cases of co-occurring multiple myeloma and lung cancer in patients who presented with the chief complaint of pain. The diagnoses of multiple myeloma and lung cancer were supported by hematologic and biochemical investigations, as well as bone marrow and lung histopathologic examination. We provided suitable interventions for both two patients. The patients are still currently undergoing treatment and followed up closely. We first performed a bioinformatic analysis to determine commonly shared genes and pathways in the two types of cancer types. Fortunately, we identified the hub gene mitochondrial trans-2-enoyl-CoA reductase (MECR), which was overexpressed in both tumors. Survival analysis correlated higher MECR expression with poorer overall survival. Signaling pathway analysis suggested possible transduction pathways implicated in the co-occurrence of both tumors. The clinical cases combined with bioinformatic analysis may provide insight for the pathogenesis of synchronous tumors.

Case report: simultaneous occurrence of multiple myeloma and non-Hodgkin lymphoma treated by CAR T therapy.

Project description:RationaleB cell lymphoma can co-occur with multiple myeloma (MM), and the prognosis in this case is usually poor. We propose the combination of CD19-chimeric antigen receptor (CAR) T cells and BCMA-CAR T cells for the treatment of such patients to obtain a superior prognosis.Patient concernsWe present a 50-year-old patient with previous B cell lymphoma and subsequent multiple myeloma (MM).DiagnosisA diagnosis of B cell lymphoma and MM was made.InterventionsThe patient was treated with a combination of haploidentical CD19-chimeric antigen receptor (CAR) T cells and BCMA-CAR T cells.OutcomesAfter CAR T cell therapy, the monoclonal plasma cells in the bone marrow and M protein disappeared.LessonsThe combination therapy of CD19- and BCMA-CAR T cells is an effective measure to treat patients with concomitant or borderline cases of B cell lymphoma and MM.

Multiple myeloma with testicular involvement: A case report.

Project description:A case of multiple myeloma with testicular involvement is rare. We report a 72-year-old male with testicular infiltration as extramedullary disease of IgD λ-type multiple myeloma. The patient received systemic treatment, which included high orchiectomy, anticancer chemotherapy, and radiation therapy for bone metastasis. Eight months after the initial diagnosis, he remains alive. The testis is a rare location for extramedullary disease of multiple myeloma. Testicular involvement of multiple myeloma indicates a poor prognosis. The particular treatment strategy for extramedullary disease in multiple myeloma remains unclear. Testicular involvement of multiple myeloma is reviewed and discussed in this paper.

Multiple chromoanasynthesis in a rare case of sporadic renal leiomyosarcoma: case report

Project description:Renal leiomyosarcomas (LMS) are extremely rare neoplasms with aggressive behaviour and poor survival prognosis. The most frequent somatic events in leiomyosarcomas are mutations in TP53, RB1, ATRX and PTEN genes, chromosomal instability and chromoanagenesis. By using chromosomal microarray analysis we identified monosomy of chromosomes 3 and 11, gain of Xp (ATRX) arm and three chromoanasynthesis regions (6q21-q27, 7p22.3-p12.1 and 12q13.11-q21.2), with MDM2 and CDK4 oncogenes copy number gains, whereas no CNVs or tumor specific SNVs in TP53, RB1 and PTEN genes were observed.

Clonal cytogenetics changes in progression of multiple myeloma to extramedullary relapse and plasmocellular leukemia – case report

Project description:Extramedullary relapse (EM) of multiple myeloma (MM) is defined as infiltration of plasma cells (PC) outside of the bone marrow. EM is an aggressive form of the disease with a dismal outcome. We present cytogenetic findings of a 52-year-old female patient who was diagnosed with MM in 2008 and progression of MM to EM and plasmocellular leukemia retrospective analysis of TP53 mutation status showed presence of 2 known missense mutations in exon 6 (c.632C>T) and exon 7 (c.700T>C). EM relapse of this patient was connected to a change of the entire genome profile. We suppose that the extramedullary lesion originated by an expansion of one clone of tumor plasma cells from the bone marrow, which was confirmed by identical genomic profile of both tested samples. Thus, change of ploidy status should be considered as potential hallmark of adverse course of the disease.

Case Report: Molecular Profiling Facilitates the Diagnosis of a Challenging Case of Lung Cancer with Choriocarcinoma Features

Project description:Accurate diagnoses are crucial in determining the most effective treatment across different cancers. In challenging cases, morphology-based traditional pathology methods have important limitations, while molecular profiling can provide valuable information to guide clinical decisions. We present a 35-year female with lung cancer with choriocarcinoma features. Her disease involved the right lower lung, brain, and thoracic lymph nodes. The pathology from brain metastasis was reported as “metastatic choriocarcinoma” (a germ cell tumor) by local pathologists. She initiated carboplatin and etoposide, a regimen for choriocarcinoma. Subsequently, her case was assessed by pathologists from an academic cancer center, who gave the diagnosis of “adenocarcinoma with aberrant expression of β-hCG” and finally pathologists at our hospital, who gave the diagnosis of “poorly differentiated carcinoma with choriocarcinoma features”. Genomic profiling detected a KRAS G13R mutation and transcriptomics profiling was suggestive of lung origin. The patient was treated with carboplatin/paclitaxel/ipilimumab/nivolumab followed by consolidation radiation therapy. She had no evidence of progression to date, 13 months after the initial presentation. The molecular profiling could facilitate diagnosing of challenging cancer cases. In addition, chemoimmunotherapy and local consolidation radiation therapy may provide promising therapeutic options for patients with lung cancer exhibiting choriocarcinoma features.

Proteasome inhibitor-induced coronary vasospasm in multiple myeloma: a case report.

Project description:BackgroundCoronary vasospasm is an increasingly recognized cause of myocardial infarction or myocardial ischaemia in patients without obstructive coronary artery disease. A thorough medication review may identify drugs or toxins that could trigger coronary vasospasm. This case provides mechanistic insight into the off-target effect of proteasome inhibition leading to coronary vasospasm in a patient referred with chest pain consistent with typical angina.Case summaryA 72-year-old lady presented with anginal chest pain at rest with electrocardiogram evidence of myocardial ischaemia who was referred for invasive coronary angiography. This demonstrated minor coronary disease without an obstructive lesion. Vasoreactivity testing revealed diffuse coronary vasospasm of the left anterior descending artery. Carfilzomib was identified as the trigger for coronary vasospasm. Symptoms resolved without recurrence after appropriate treatment including cessation of the triggering agent.ConclusionCoronary spasm is a rare but important adverse reaction to proteasome inhibitors. This case supports the clinical utility of invasive coronary vasoreactivity testing in patients with ischaemia with no obstructive coronary artery disease.

Multiple myeloma in a patient with chronic myeloid leukemia: A case report.

Project description:Chronic myeloid leukemia (CML), a clonal myeloproliferative disorder of pluripotent hematopoietic stem cells, results from the Philadelphia chromosome (Ph) chromosome. The Ph is from a translocation, t(9;22)(q34q11), that creates a BCR-ABL fusion gene, which is transcribed into proteins with abnormal tyrosine kinase activity, driving the abnormal proliferation of white blood cells. Multiple myeloma (MM) is a proliferation disorder of plasma cells derived from a single clone, which may lead to uncontrolled growth, kidney injury, destructive bone lesions, hypercalcemia and anemia. It is extremely rare that MM and CML should occur in the same patient either synchronously or metachronously. To date, MM accompanied with CML has only been reported in limited studies, and the the cause behind the occurrence of both malignancies together is not understood. With the advent of novel therapies, the survival time in patients with CML and MM has improved. Therefore, the further investigation of the pathophysiology and clinical characteristics of these cases is valuable. The present study reports the case of a 79-year-old male who had been diagnosed with CML and treated with tyrosine kinase inhibitor, and then developed immunoglobulin G-κ MM after 6 years. This report should provide valid raw data for clinical research.

Case Report: Coexistence of Multiple Myeloma and Auricular Chondritis in VEXAS Syndrome

Project description:Vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome is an inflammatory disorder caused by somatic UBA1 variants, which are sometimes associated with hematological disorders, including myelodysplastic syndrome (MDS). VEXAS syndrome often overlaps with rheumatic diseases, including relapsing polychondritis. Here, we describe a case of VEXAS syndrome with auricular chondritis and exceptional multiple myeloma (MM). An 83-year-old man was diagnosed with MM, which was treated once by lenalidomide hydrate obtaining a partial response, but the patient did not desire further aggressive therapy. Although the treatment was effective, progressive macrocytic anemia and inflammation of both the ears emerged over the following 2 months. The histological examination of the auricle skin revealed that the perichondrial area was infiltrated by inflammatory cells, leading to the diagnosis of auricular chondritis. He was treated with oral prednisolone 40 mg/day, and his symptoms rapidly resolved. The re-evaluation of the histopathological bone marrow findings revealed vacuoles in the myeloid precursor cells without myelodysplasia-related changes. Sanger sequencing of UBA1 was performed using genomic DNA from peripheral blood leukocytes and revealed a somatic variant (c.122T>C:p.Met41Thr) consistent with VEXAS syndrome. This demonstrates that patients with chondritis can have complications with MM despite the absence of underlying MDS. A strong association exists between UBA1 variants and the risk of MDS; however, it remains elusive whether somatic UBA1 variants contribute to the development of plasma cell dyscrasia without MDS. Hence, we discuss the possible relationship between auricular chondritis and MM on a background of VEXAS syndrome.

Multiple Myeloma Mimicking a Small Vessel Vasculitis Presentation.

Project description:Multiple myeloma can have different clinical manifestations, and not all patients present with classic CRAB component. We describe a 46-year-old woman admitted to our hospital with a complaint of a bluish-to-black discoloration of the second toe that was rapidly progressive and acute kidney injury. We documented a Kappa light chain monoclonal gammopathy, increased presence of plasmacytes in bone marrow aspiration, and multiple lytic bone lesions, which led to a diagnosis of multiple myeloma. Although multiple myeloma presenting with blue finger syndrome is uncommon, it must always be considered as a differential diagnosis with this clinical finding.
