Entire Body System
Fever
- Systemic symptoms, mainly fever or weight loss, are present in[ncbi.nlm.nih.gov]
- The patient, a 33-year-old man, had cough, dyspnea, fever, superior vena cava syndrome, and a mediastinal bulky tumor. A biopsy showed that the latter was characterized by large cells, sclerosis, and compartmentalization.[ncbi.nlm.nih.gov]
- […] in the multicenter group (2.5 years follow-up).Short-term toxicity was manageable, but required hospitalization: the rates of grade 3 or 4 toxicity were 20% (for mucositis), 42% (for neutropenia), 29% (for thrombocytopenia), and 9% (for neutropenic fever[ncbi.nlm.nih.gov]

Fatigue
- The most common adverse reactions (reported in at least 20% of patients) were fatigue, decreased appetite, and dyspnea.[businesswire.com]
- Common symptoms breathlessness* cough or chest pain* fatigue loss of appetite enlarged lymph nodes - painless swelling in the neck, armpit or groin - often in more than one group.[lymphomation.org]
Chills
- Monitor patients for signs and symptoms of infusion-related reactions, including rigors, chills, wheezing, pruritus, flushing, rash, hypotension, hypoxemia, and fever. For Grade 3 or 4 reactions, stop infusion and permanently discontinue KEYTRUDA.[businesswire.com]
Respiratoric
Cough
- PMLBCL is characterized by a locally invasive anterior mediastinal mass, often producing cough, chest pain, dyspnea, and superior vena cava syndrome.[ncbi.nlm.nih.gov]

- Subsequently, her chest pain got worse, and she went to another clinic, where she was detected with an anterior mediastinal tumor and was referred to our hospital. Tumor biopsy with a thoracoscope was performed, and a diagnosis of PMBL was made.[dear-medic.jp]
- Common symptoms breathlessness* cough or chest pain* fatigue loss of appetite enlarged lymph nodes - painless swelling in the neck, armpit or groin - often in more than one group.[lymphomation.org]
Workup
- Workup of such cases should include extended panel of immunohistochemical stains including the B-cell transcription factors PAX-5, OCT-2 and BOB.1.[arup.utah.edu]
X-Ray
Pericardial Effusion
- Our simple indicators of International Prognostic Index score and the presence of pleural or pericardial effusion could stratify patients with primary mediastinal large B-cell lymphoma and help guide selection of treatment.[ncbi.nlm.nih.gov]
- Most PMLBCL patients have stage I-II, bulky disease, with pleural or pericardial effusions in a third of cases. Systemic symptoms, mainly fever or weight loss, are present in[ncbi.nlm.nih.gov]
- Most had features of local extension like pleuro-pericardial effusion. Absence of infradiaphragmatic lymph nodes and no bone marrow involvement at presentation. All patients required biopsy from the mediastinal mass by image guided core biopsy.[cancerres.aacrjournals.org]

Treatment
- CONCLUSIONS: Our data indicate that a third-generation regimen like MACOP-B could be considered a suitable first-line treatment.[ncbi.nlm.nih.gov]
- This article reviews the treatment approach for mediastinal lymphomas, including CHL of the nodular sclerosis subtype (CHL-NS), PMBL, and mediastinal GZL.[ncbi.nlm.nih.gov]
- Planned treatment was concluded in 43 of 53 patients; in 10 patients, I-CT was not immediately followed by IFRT.[ncbi.nlm.nih.gov]
- Treatment options for relapsed/refractory primary mediastinal large B-cell lymphoma (rrPMBCL) are limited, and prognosis is generally poor (overall response rate [ORR] 0% to 25%; 2-year overall survival 15%).[ncbi.nlm.nih.gov]
- Therefore, the need for more aggressive treatment strategies is questionable unless high-risk patients are adequately defined. Further studies are required to establish the precise role of RT.[ncbi.nlm.nih.gov]
Prognosis
- The prognosis and therapy of patients with PMLBCL is still controversial. We summarize our experience with PMLBCL at the Medical University of South Carolina between 1997 and 2000.[ncbi.nlm.nih.gov]
- These data are consistent with those reported from other centers concerning the patient's characteristics, natural history, response pattern to chemoradiation therapy, and prognosis. Response to therapy proved of prognostic significance.[ncbi.nlm.nih.gov]
- For this group of patients with homogeneous clinical characteristics, response to initial chemotherapy and MUM1 expression were associated with prognosis.[ncbi.nlm.nih.gov]
- The estimated 3-year overall and failure-free survival rates were 32% and 33%, respectively, indicating the relatively unfavorable prognosis of the patients in our series.[ncbi.nlm.nih.gov]
- Treatment options for relapsed/refractory primary mediastinal large B-cell lymphoma (rrPMBCL) are limited, and prognosis is generally poor (overall response rate [ORR] 0% to 25%; 2-year overall survival 15%).[ncbi.nlm.nih.gov]
Etiology
- For suspected immune-mediated adverse reactions, ensure adequate evaluation to confirm etiology or exclude other causes. Based on the severity of the adverse reaction, withhold KEYTRUDA (pembrolizumab) and administer corticosteroids.[businesswire.com]
- The use of tocilizumab directed at IL-6 has been shown to mitigate CRS, but the etiology and treatment of neurologic complications remain more elusive.[hematology.org]
