Follicular lymphoma (FL) is the most common subtype of indolent non-Hodgkin lymphoma. Patients with stage I disease are usually treated with radiotherapy (RT). In previous studies, mostly from the pre positron emission tomography-computed tomography (PET-CT) era, the 5 year progression-free survival (PFS) and overall survival (OS) rates of stage I disease were 60-80% and 80-93%, respectively. This study retrospectively evaluated the outcome of stage I FL which was treated with involved field RT in the PET-CT era between 2002 and 2015...

In patients with relapsed diffuse large B-cell lymphoma (DLBCL), high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is standard treatment. Here, we aim to identify factors associated with survival in patients undergoing ASCT. A total of 369 patients with relapsed DLBCL undergoing ASCT from 2000 to 2012 were identified in the Danish National Lymphoma Registry. Information on clinical and socioeconomic factors was obtained from medical records and national registries. Factors associated with survival were assessed using a Cox's proportional hazards model...

Granuloma faciale (GF) is a rare, inflammatory, cutaneous disorder of unknown aetiology. It presents clinically as one or several well-circumscribed violaceous papules, plaques, and nodules almost exclusively confined to the facial region. Rarely, extrafacial lesions can occur, most often on sun-exposed sites. We report a case of extrafacial GF in a 63-year-old male with indolent lymphoma, who presented with plaques involving the right preauricular region and left posterior axilla. The clinical and histopathological findings were consistent with GF...

Bcl-2 proteins, such as B-cell lymphoma (Bcl-2) protein, myeloid cell leukemia sequence 1 (Mcl-1) protein, has been implicated in the progression and survival of multiple tumor types and become a validated and attractive target for cancer therapy. In this work, a series of 1-phenyl-1H-indole derivatives has been designed and synthesized. The preliminary biological studies (binding assay for Bcl-2 proteins and MTT assay) suggested that some active compounds showed potent inhibitory activities on Bcl-2/Mcl-1 without binding on Bcl-XL...

PURPOSE: B-cell lymphomas must acquire resistance to apoptosis during their development. We recently discovered BCLW, an anti-apoptotic BCL2 family member thought only to contribute to spermatogenesis, was overexpressed in diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma. To gain insight into the contribution of BCLW to B-cell lymphomas and its potential to confer resistance to BCL2 inhibitors, we investigated the expression of BCLW and the other anti-apoptotic BCL2 family members in six different B-cell lymphomas...

Primary cutaneous large B‑cell lymphomas (PCBLT), EBV-positive large B‑cell lymphomas, not otherwise specified (EBV+ DLBCL, NOS), and primary cutaneous intravascular large B‑cell lymphomas (PCIVLBL) are recognized as cutaneous lymphomas with intermediate to poor prognosis. Differentiation from indolent B‑cell lymphomas or other pathologies of the skin can be complex, both clinically and histologically, but vital for the outcome of the patient. The combination of immunotherapy and polychemotherapy regimens, such as R‑CHOP, has led to significant improvements in prognosis, especially in diffuse large B‑cell lymphomas...

Nodular pulmonary amyloidosis is a very rare form of localized amyloidosis involving the lung, with very little known about its nature. It is usually associated with indolent B cell lymphoproliferative disorder and also connective tissue disorders. No definite treatment guideline exists. Many patients respond to chemotherapy with low risk of progression and a 'wait and watch' strategy is also considered a valid treatment option. In this report the authors present a case of nodular pulmonary amyloidosis with pulmonary mucosa associated lymphoid tissue (MALT) lymphoma that presented with features of metastatic malignant disease and after definitive diagnosis decided not to undergo treatment...

Although patients with indolent B-cell lymphomas have a relatively good survival rate, conventional chemotherapy is not curative. Disease courses are typically characterized by multiple relapses and progressively shorter response duration with subsequent lines of therapy. There has been an explosion of innovative targeted agents in the past years. This review discusses current knowledge on the etiology of indolent B-cell lymphomas with respect to the role of micro-organisms, auto-immune diseases, and deregulated pathways caused by mutations...

Adult T-cell lymphoma/leukemia (ATL) is a rare T-cell lymphoproliferative neoplasm caused by human T-lymphotrophic virus 1. In its more common, aggressive forms, ATL carries one of the poorest prognoses of the non-Hodgkin lymphomas. The disease has clinical subtypes (ie, acute, lymphoma, chronic, and smoldering forms) defined by the presenting features, and therefore, the clinical course can vary. For the smoldering and lower-risk chronic forms, combinations involving antiviral therapies have shown some success...

Primary cutaneous acral CD8+ T-cell lymphoma (acral CD8+ TCL) is a new provisional entity characterized by acral skin lesions and an indolent course. We describe an extraordinary case characterized by relapsed nodules with CD8+ cytotoxic infiltrates on the left ear. After 35 years, the skin lesions spread to other acral sites, and a mass with the same histological features as the other skin lesions appeared on the nose. Multiple courses of chemotherapy led to stable disease. Histological examinations carried out at different times showed the gradual transformation of the neoplastic cells with an increased proliferation index...

Among the group of primary cutaneous lymphomas several subtypes have very low incidence rates. Based on the revision of the WHO classification for lymphoid neoplasms (2016), an overview of rare cutaneous T‑cell lymphoma (CTCL) subtypes is given and therapeutic approaches are detailed. The prognosis of the different subtypes is highly variable underlining the importance of adequate stage and subtype adapted treatment. In cases of indolent subtypes topical treatment, e. g. topical corticosteroids or UV phototherapy are often sufficient...

Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is a B-cell lymphocytic neoplasm with indolent clinical course. If identified early, observation is opted. Many variables lead to the initiation of treatment. Authors describe a 62-year-old male presenting with shortness of breath and found to have white cell count of 1360 × 10(9)/L and subsequently was diagnosed with CLL/SLL. The patient received leukapheresis along with tumor lysis treatment and systemic chemotherapy with fludarabine, cyclophosphamide, and rituximab regimen...

BACKGROUND: Follicular lymphoma (FL) is heterogeneous. Although FL Grade 3B (FL3B) is treated as aggressive FL (aggFL), an optimal approach to FL Grade 3A (FL3A) remains unclear because few data exist on clinical outcomes on the basis of subclassification of FL Grade 3 (FL3) since the introduction of rituximab. We report outcomes of FL3 in the rituximab era. PATIENTS AND METHODS: We identified and analyzed a retrospective cohort of 53 patients with FL3A, 3B, and FL Grade 3 with areas of diffuse large B-cell lymphoma (DLBCL)...

AIMS: Primary cardiac lymphoma (PCL) is a rare neoplasm. PCL is fatal, unless it is diagnosed and treated early. Recently, a small number of cases of diffuse large B cell lymphoma (DLBCL) arising within atrial myxoma have been reported in immunocompetent patients and showed aggressive histologic features but an indolent clinical behaviour. METHODS AND RESULTS: We presented four unusual cases of Epstein-Barr virus (EBV)-positive DLBCL arising within atrial myxoma with detailed clinical, histologic, immunophenotypic and genotypic features in immunocompetent patients, and reviewed the literature for 11 similar cases...

The use of novel B cell receptor signaling inhibitors results in high response rates and long progression-free survival in patients with indolent B cell malignancies, such as chronic lymphocytic leukemia, follicular lymphoma, mantle cell lymphoma and Waldenstroms macroglobulinemia. Ibrutinib, the first-in-class inhibitor or Bruton's tyrosine kinase, and idelalisib, the first-in-class inhibitor of phosphatidylinositol 3-kinase δ have recently been approved for several indolent B cell malignancies. These drugs especially foresee in previously unmet needs for patients with relapsed or refractory disease, high-risk cytogenetic or molecular abnormalities or with comorbidities...

Primary cutaneous B‑cell lymphomas are rarely encountered and represent 25% of all cutaneous lymphomas. Follicular B‑cell lymphoma and marginal zone lymphoma belong to indolent subtypes which as a rule have no systemic dissemination and, thus, a mostly unchanged life expectancy. Therefore, skin-directed treatment options such as excision or radiotherapy are usually sufficient to control the disease. In contrast, cutaneous diffuse large B‑cell lymphoma and EBV-associated B‑cell lymphomas of the skin belong to more aggressive entities which demand a systemic first-line upfront therapy with R‑CHOP...
