INTRODUCTION: Cancer of unknown primary (CUP) is a tumour metastasis with no detectable primary origin. A secondary neoplasm (SN) is defined as a tumour secondary to a prior tumour treatment and has no histological relation to that primary tumour. CASE PRESENTATION: The authors report a case of a 72-year-old female patient who presented with back pain and had a history of non-Hodgkin lymphoma (NHL) treated with RCHOP 12 years ago. MRI showed a compression fracture in T5 and T7 vertebrae, while the PET/computed tomography (CT) only showed hypermetabolic lytic bone lesions in these vertebrae...

A 59-year-old woman diagnosed with a Grade I chondrosarcoma in T7 underwent total en bloc vertebrectomy. Analysis of the surgical piece established diagnosis of a Grade 1 chondrosarcoma confined to T7. Surprisingly, an infiltration with diffuse large B-cell lymphoma was found. Systemic disease was ruled out and diagnosis was established as intracompartmental Grade 1 chondrosarcoma colliding with intraosseous extranodal diffuse large B-cell lymphoma. Resection of chondrosarcoma was considered complete and treatment with four cycles of RCHOP was indicated...

BACKGROUND: The implication of the presence of tumor-infiltrating T lymphocytes (TIL-T) in diffuse large B-cell lymphoma (DLBCL) is yet to be elucidated. We aimed to investigate the effect of TIL-T levels on the prognosis of patients with DLBCL. METHODS: Ninety-six patients with DLBCL were enrolled in the study. The TIL-T ratio was measured using QuPath, a digital pathology software package. The TIL-T ratio was investigated in three foci (highest, intermediate, and lowest) for each case, resulting in TIL-T-Max, TIL-T-Intermediate, and TIL-T-Min...

For over two decades, Rituximab and CHOP combination treatment (rCHOP) has remained the standard treatment approach for diffuse large B-cell lymphoma (DLBCL). Despite numerous clinical trials exploring treatment alternatives, few options have shown any promise at further improving patient survival and recovery rates. A wave of new therapeutic approaches have recently been in development with the rise of immunotherapy for cancer, however, the cost of clinical trials is prohibitive of testing all promising approaches...

RCHOP is the standard of care for patients with diffuse large b-cell lymphoma (DLBCL) but failures occur in approximately 40% of them. We performed a meta-analysis of 21 randomized controlled trials (RCTs) comparing experimental regimens with RCHOP. We searched the database of PubMed with proper criteria, and data of efficacy (Progression Free Survival-PFS) in the ITT population were extracted and analyzed. Cross comparisons of RCTs were performed by using the CINEMA software. Odds ratio (OR) and 95% confidence intervals (95%, CI) are reported...

The standard treatment for Diffuse Large B-Cell Lymphoma (DLBCL) is rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (RCHOP). However, many patients require subsequent treatment after relapsed disease. The ABC subtype of DLBCL (ABC-DLBCL) has a worse prognosis, and the PHOENIX trial explored adding ibrutinib to RCHOP for this patient population. The trial showed favorable outcomes for younger patients, and our study aimed to inform clinical decision-making via a cost-effectiveness model to compare RCHOP with and without ibrutinib (I-RCHOP)...

BACKGROUND: In early stage diffuse large B-cell lymphoma (ESDLBL), tumor bulkiness is an important determinant of treatment and prognosis. Tumor bulk is usually measured on transverse computed tomography (CT) plane and variably defined from 5 to 10 cm. OBJECTIVES: Our study aims to investigate the prognostic significance of bulky disease measured on CT coronal and transverse planes and to evaluate the outcome of patients with bulky disease. METHODS: Patients with ESDLBL and treated with rituximab, cyclophosphamide, doxorubicin, and prednisolone (RCHOP) with or without radiotherapy were included...

This case report presents a 43-year-old female with a history of common variable immunodeficiency (CVID) and a recent diagnosis of mesenteric volvulus. The patient presented with symptoms of partial small bowel obstruction and was diagnosed with obstruction and mesenteric volvulus primarily affecting the proximal jejunum. During the exploratory laparotomy, a probable polyposis syndrome and a possible adenocarcinoma of the small bowel were identified. Pathological examination confirmed the presence of B-cell lymphoma in the proximal jejunum...

INTRODUCTION: Non-Hodgkin lymphoma of the duodenum with manifestation of hematemesis, melena, and obstructive jaundice is a rare occurrence. CASE PRESENTATION: A 47-year-old Indonesian man presented with symptoms of hematemesis of 3×/day, melena, abdominal pain, decreased appetite, and a weight loss (2 kg). The patient had symptoms of weakness, jaundice, pale conjunctiva, and experienced palpable discomfort in the epigastric region (VAS of 6). An abdominal ultrasonography revealed a heterogeneous cystic tumor mass measuring 45 × 29 mm located in the pancreas head...

Castleman disease (CD) describes a group of rare heterogeneous lymphoproliferative disorders characterized by enlarged hyperplastic lymph nodes. It is classified into unicentric CD (UCD) and multicentric CD (MCD). The present retrospective study examined the data of 11 patients with CD diagnosed and treated at a tertiary cancer center from 2017 to 2022. The median age of the study group was 41 years (range, 24 to 68 years). There were 8 males and 3 females. In total, 7 patients were diagnosed with UCD and 4 patients with MCD...

Drug combination therapy is a main pillar of cancer therapy. As the number of possible drug candidates for combinations grows, the development of optimal high complexity combination therapies (involving 4 or more drugs per treatment) such as RCHOP-I and FOLFIRINOX becomes increasingly challenging due to combinatorial explosion. In this paper, we propose a text mining (TM) based tool and workflow for rapid generation of high complexity combination treatments (HCCT) in order to extend the boundaries of complexity in cancer treatments...

Composite lymphoma implies the presence of two or more morphological and immunophenotypical subtypes of lymphoma in a single tissue or organ. Composite lymphoma with concurrent mantle cell lymphoma (MCL) and classical Hodgkin lymphoma is extremely rare. In this case report, we present the case of a 70-year-old male who was diagnosed with a composite of MCL and classical Hodgkin lymphoma (cHL) and achieved near-complete resolution with chemoimmunotherapy. To the best of our knowledge, this is the first case of this kind demonstrating the effectiveness of a combination chemoimmunotherapy regimen leading to complete remission in composite lymphoma involving MCL and cHL...

PURPOSE/OBJECTIVE(S): Gray zone lymphoma (GZL) is a relatively rare disease predominantly affecting young adults with purportedly poor outcomes with current treatment approaches. The role of radiation therapy (RT) in the management of GZL is not well established. This is the largest study to report on the outcomes of GZL patients treated with and without RT. MATERIALS/METHODS: A retrospective review of 30 patients with GZL treated across 3 institutions from 2009 to 2021 was performed...

PURPOSE/OBJECTIVE(S): CD19-directed chimeric antigen receptor T-cell therapy (CART) has led to remarkable outcomes in patients with relapsed or refractory (R/R) non-Hodgkin's lymphomas (NHL), yet ∼50% of patients relapse. Predictive factors associated with high risk of relapse following CART have been identified in the literature. Studies have shown a potential improvement in outcomes with the use of bridging radiation (RT) prior to CART. The purpose of this study is to determine the incidence of patients meeting high risk criteria who have disease that could be encompassed in a standard radiation plan prior to CART...

BACKGROUND: Treatment with CHOP-based chemotherapy with consolidative radiotherapy (CRT) for primary mediastinal B cell lymphoma (PMBCL) has been the standard approach in the pre-rituximab era. Overtreatment with CRT for patients who may have already been cured by primary immunochemotherapy in the rituximab era is a significant concern due to the long-term toxicity associated with radiotherapy. Positron emission tomography (PET) may help to identify patients who may not benefit from further CRT...

BACKGROUND: Mantle cell lymphoma (MCL) of the gastrointestinal tract is a rare malignancy, accounting for about 0.2% of malignant colorectal tumors. MCL synchronous with rectal adenocarcinoma is extremely rare. We know of only a few cases reported in the literature. We describe the case of a patient with synchronous rectal adenocarcinoma and intestinal MCL. CASE SUMMARY: A 63-year-old man was admitted to our hospital due to abdominal pain and hematochezia over the past month...

BACKGROUND: Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL), recently known as nodular lymphocyte-predominant B-cell lymphoma (NLPBL), accounts for 5%-10% of Hodgkin lymphoma (HL). Different morphologic patterns of NLPBL are identified and categorized as typical patterns (type A and B) and variant histologic patterns (types C, D, E, and F). PATIENTS AND METHOD: We investigated different morphologic patterns, CD30 and IgD expression in pediatric patients with NLPBL diagnosed at the Children's Cancer Hospital Egypt...

Primary cutaneous lymphomas are a group of lymphomas that originate in the skin at the time of diagnosis. We report a case of a 45-year-old female who presented with cutaneous lesions that were unresponsive to conservative management. A biopsy was performed, which was consistent with primary cutaneous B-cell lymphoma. She received four cycles of chemotherapy and her end-of-treatment positron emission tomography (PET)-computed tomography (CT) scan showed a complete metabolic response.

INTRODUCTION: Toxicity risk evaluation based on frailty assessment is recommended for treatment individualization in old adults with diffuse large B-cell lymphoma (DLBCL). However, no specific assessment method to guide decision-making has been established yet. Here, we implement a therapeutic algorithm based on the information obtained in an updated comprehensive geriatric assessment (CGA) to assess the value that other prognostic factors add to frailty. MATERIAL AND METHODS: We prospectively recruited 31 patients aged 70 or older recently diagnosed with DLBCL...

Background Non-Hodgkin lymphomas (NHL) represent a group of lymphoproliferative disorders, with a limited understanding of their clinical spectrum, primary extranodal variety, histopathology, and immunohistochemistry, particularly in developing countries. The objective of this study was to evaluate the clinicopathological characteristics and survival rates of NHL patients treated at King Khaled Hospital in Najran City, Saudi Arabia. Method In this retrospective chart review of NHL cases that received chemotherapy at the Oncology Center of King Khaled Hospital in Najran City, Saudi Arabia, between 2014 and 2021, we evaluated the clinicopathological features, survival rate, and associated factors...
