Ning Y, He H, Li Q, Zhao D, Xie D. The prognosis of patients with primary pulmonary mucosa-associated lymphoid tissue lymphoma: Treated with surgery or chemotherapy? Eur J Cardiothorac Surg 2024; 65:ezae064. [PMID: 38400749 DOI: 10.1093/ejcts/ezae064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 01/30/2024] [Accepted: 02/21/2024] [Indexed: 02/26/2024] Open
Abstract
OBJECTIVES The goal of this project was to evaluate the effect of surgical treatment and the long-term survival of patients with staged IE/IIE pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. METHODS From January 2004 to December 2018, we retrospectively analysed 96 patients diagnosed with low-stage primary pulmonary MALT lymphoma according to the modified Ann Arbor staging system (IE/IIE). We compared the outcomes of different treatment modalities for staged IE/IIE MALT lymphoma. Progression-free survival (PFS) and overall survival were estimated using Kaplan-Meier curves, and the differences were compared using the log-rank test. The Cox proportional hazards model was used in this study. RESULTS The median PFS time of low-staged MALT lymphomas was 118 months. The overall survival and PFS of the radical surgery group and the biopsy + chemotherapy group suggested no significant difference (P = 0.63, P = 0.65). Patients positive for Blc-2 and Ki-67 suffered from a compromised PFS (P = 0.023, P = 0.006). The Cox adjusted proportional hazards model analysis suggested that surgical procedures were not protective factors for patients with low-staged (IE/IIE) pulmonary MALT lymphoma, whereas being positive for Blc-2 and Ki-67 was a risk factor for patients with low-staged pulmonary MALT lymphoma (hazard ratio: 9.567; P = 0.044; hazard ratio: 6.042, P = 0.049). CONCLUSIONS Our findings suggested that for staged IE/IIE pulmonary MALT lymphoma, radical surgical resection did not provide a survival benefit compared with chemotherapy after biopsy. Thus, radical surgery may be avoided unless biopsy is necessary for a diagnosis that requires sublobar resection. For those lesions that were Blc-2- or Ki-67-positive, compromised survival may be suggested.

Abstract
OBJECTIVE The objective of this study is to investigate the clinical manifestations, computed tomography (CT) findings, and prognosis of primary pulmonary mucosa-associated lymphoid tissue lymphoma (MALToma) with the improved health awareness nowadays. METHODS Clinical data and CT images of patients with pathologically confirmed MALToma from October 2012 to October 2021 were retrospectively analyzed. RESULTS Eighteen MALToma patients were included in the study (8 men and 10 women; mean age, 56.17 years; range, 33-73 years). Six men had a long-term history of smoking (>20 years). One patient had an autoimmune disease (Sjögren syndrome). Eight patients (44.44%) were asymptomatic, and 10 (55.56%) had mild chest or systemic symptoms. Most lesions (88.89%) were subpleural or located along the bronchovascular tree. According to the CT characteristics, the lesions were divided into 4 groups: nodular type (n = 8; 44.44%, including 5 solid nodules and 3 ground-glass nodules), mass type (n = 4, 22.22%), patch or consolidate type (n = 5, 27.78%), and mixed type (n = 1, 5.56%). Air bronchogram (11/18, 61.11%) and angiogram sign (8/16, 50%) were the most frequent CT findings and may help differential diagnosis. The patients were misdiagnosed with lung cancer (n = 11, 61.11%), inflammatory or chronic inflammatory disease (n = 4, 22.22%), bronchiectasis accompanied by infection (n = 1, 5.56%), diffuse interstitial lung disease (n = 1, 5.56%), and granuloma or tuberculosis (n = 1, 5.56%). The prognosis of all patients was favorable; 1 patient was lost to follow-up. CONCLUSIONS Nowadays, patients with MALToma are usually asymptomatic or paucisymptomatic. Nodular lesions, including ground-glass nodules, are the most common presentation. Mucosa-associated lymphoid tissue lymphoma is most likely misdiagnosed as lung cancer. Lesions located in the subpleural areas or along the bronchovascular tree and presenting with an air bronchogram or angiogram sign could indicate a MALToma diagnosis.

Abstract
BALT lymphoma is a rare B-NHL with a favorable prognosis. We here report on two patients with nonspecific symptoms: one showed as major symptom severe thrombocytopenia and the other dyspnea and dry cough, thereby suggesting an inflammatory focus in the lungs. There is no standard of care established yet. Both patients were successfully treated with rituximab and bendamustine. Thus, combined immunochemotherapy should be considered as first-line therapy as in other MALT lymphomas, if the treatment/eradication of an underlying chronic inflammatory disorder/trigger factor can be excluded.

Abstract
Here we describe a case of pleural extranodal marginal zone lymphoma presenting as bilateral chylothorax which has not been reported in the literature prior to this. Primary pleural lymphomas are a rare entity most commonly associated with chronic infections, autoimmune conditions or long-standing pyothorax which were not seen in this case. Chylous pleural effusions in this patient were successfully managed with chemotherapy for the underlying lymphoma.

Abstract
Background The retrospective study was mainly performed to determine the clinical symptoms and radiological characteristics of primary pulmonary lymphoma (PPL) to improve the recognition and diagnosis of the disease. Methods Between June 2007 and June 2019, the clinical data and radiological images of the 16 patients with PPL confirmed by pathology were retrospectively analyzed. Results Among the 16 patients with PPL (6 males and 10 females, aged 32 to 72 years, with a median age of 55.13 years), 9 patients were mucosa-associated lymphoid tissue lymphoma (MALT) and 7 patients were diffuse large B-cell lymphoma (DLBCL); all of the patients did not suffer from autoimmune disease [such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), or Sjogren’s syndrome (SSS)]; and 11 patients had a long-term smoking history from 10 to 40 years. The common clinical symptoms were as follows: chest discomfort (n=8), cough (n=10), chest pain (n=7), fever (n=6), apnea (n=1), fatigue (n=4) and weight loss (n=3), however, 6 cases did not show clear symptoms at the time of diagnosis. Blood tests revealed anemia (n=6), thrombocytopenia (n=2), lactate dehydrogenase (LDH) level (n=7), C-reactive protein (CRP) (n=9), erythrocyte sedimentation rate (ESR) (n=8) and no tumor-related indexes were detected abnormal. The chest radiological images showed a total of 8 cases with multiple masses, 2 cases with different types of nodes, 4 cases with patchy infiltration or consolidation shadow, with or without an air bronchogram, and 2 cases with a mixed manifestation. All the lesions were only involved in unilateral lung (13 right, 3 left), none of them located on bilateral lung fields. At the time of admission, the patients were misdiagnosed as lung cancer (n=9), pneumonia (n=5), tuberculosis (n=1), and diffuse interstitial lung disease (n=1). Then final pathological diagnosis was confirmed by surgery (n=9), percutaneous lung biopsy (n=5), and bronchoscopic biopsy (n=2). Conclusions PPL is a rare disease, though clinical symptoms and radiological characteristics are not typical, they serve as significant clues for the diagnosis and differential diagnosis. Accurate diagnosis mainly depends on histopathological examination, however, conducting a retrospectively study could improve and enrich our knowledge to the disease and reduce inappropriate treatments.

Abstract
Pulmonary nodules have a broad differential diagnosis with primary lung cancer, lung metastases, benign tumors, carcinoid tumors, and infectious granulomas as their common cause. While relatively rare, pulmonary lymphoproliferative disorders such as primary pulmonary lymphomas, primary pulmonary plasmacytomas, secondary lymphomas involving the lung, multiple myeloma involving the lung, leukemias involving the lung should be considered in these patients presenting with lung nodules. Primary pulmonary non-Hodgkin’s lymphoma (NHL) is an extremely rare lung tumor accounting for 0.4% of all lymphomas. Mucosa-associated lymphoid tissue (MALT) lymphoma accounts for about 70%-90% of all primary pulmonary lymphomas, constituting less than 0.5% of all the lung neoplasms. Though it usually remains localized, it is a clonal B-cell neoplasm with a potential for systematic spread and transformation to an aggressive B-cell lymphoma. We hereby discuss the case of a 66-year-old woman with primary pulmonary MALT lymphoma.

Abstract
Pulmonary involvement in primary Sjögren's syndrome (pSS) is an understudied entity with important clinical implications. Its prevalence has been reported in up to 20% of pSS patients. Pulmonary manifestations of pSS are diverse with involvement of airway and/or lung parenchyma. Histopathology of lung lesions suggests a predominance of submucosal mononuclear cell infiltration consisting predominantly of CD4+ T cells. Current understanding of the pathophysiology of lung disease in pSS suggests a similar process driving the pulmonary process as those in the salivary glands, with epithelial cells playing a critical role in the initiation, maintenance, and symptomatology of the disease. Clinical manifestations of lung involvement in pSS are as varied as the underlying pathology and can be vague and non-specific, thus delaying diagnosis. Management options depend on the underlying pathology but are generally limited due to lack of systematic randomized controlled trials. This review helps summarize our current understanding of lung involvement in pSS.

Abstract
Ewing sarcoma/peripheral primitive neuroectodermal tumors (ES/pPNET), a member of the Ewing sarcoma family of tumors, is a malignant soft tissue tumor with small undifferentiated neuroectodermal cells. Primary trachea-bronchial ES/pPNET is very rare. The most common pulmonary ES is due to a metastasis. We describe a case of ES/pPNET which originated in the left basal trunk bronchus. The patient was a 30-year-old male, presenting with irritable cough and fever for 10 days. A tumor of 60 mm in diameter was found in the left basal trunk bronchus, extending to the left lower lobe. No distant metastases were detected. Histopathological examination revealed a malignancy of ES/pPNET with a diffuse proliferation of round cells, a Flexner-Wintersteiner rosette formation and positive staining for CD99. The patient was successfully treated with a combination of left lower lobectomy and adjuvant chemotherapy and has remained disease-free for approximately 18 months at follow-up. This case highlights that ES/pPNET should be considered as a differential diagnosis in cases of trachea-bronchial tumors.

Abstract
Purpose Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a rare entity. To date, the optimal treatment for this disease is still under debate. The aim of this study was to analyze and summarize the clinical manifestations and therapeutic experience of 18 pulmonary MALT lymphoma patients to collect information about the optimal treatment modality. Patients and methods A retrospective analysis was performed in patients who were diagnosed with pulmonary MALT lymphoma at the Chinese People’s Liberation Army General Hospital from April 1995 to April 2016. Results Clinical data of 18 patients were available. The median age was 55 (range, 34–67) years. Also, 61.1% of the patients were male. Only 33.3% had a history of smoking and 27.8% of the patients had tuberculosis. Treatment modalities included surgery alone in 1 patient (5.6%), chemotherapy in 10 patients (55.5%), surgery in combination with chemotherapy in 6 patients (33.3%) and observation in 1 patient (5.6%). Over the median observation period of 93 months, 2 patients died, the median progression-free survival was 6 years, and the estimated 5- and 10-year overall survival rates were 94.1% and 83.7%, respectively. The survival data confirmed the indolent nature of the disease. There was no difference in progression-free survival between the chemotherapy group and the surgery in combination with chemotherapy group. Conclusion Pulmonary MALT lymphoma tended to be an indolent disease. In order to preserve the lung function and reduce the risks associated with surgery, chemotherapy might be an optimal choice for the treatment of pulmonary MALT lymphoma.

Abstract
OBJECTIVES To evaluate clinical presentations, treatment modalities, and outcomes of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma by stage strata. METHODS We retrospectively reviewed 51 patients diagnosed with pulmonary MALT lymphoma between January 2003 and December 2015. To compare treatment modalities and outcomes, we stratified the patients into low-stage (IE/IIE) and high-stage (IIIE/IVE) groups using modified Ann Arbor staging. Progression-free survival was estimated using Kaplan-Meier curves, and differences were compared using the log-rank test. A hazard ratio of progression by stage strata, adjusted for other clinical variables, was determined using a Cox adjusted proportional hazards model. RESULTS The majority of patients had stage IE disease (76.5%; 39 of 51). With advancing stage, patients were more likely to have respiratory and B symptoms and higher International Prognostic Index scores. The most common treatment modality was surgical resection in low-stage patients (33 of 43) and chemotherapy in high-stage patients (7 of 8). At a median follow-up of 40.7 months, progression-free survival was longer for low-stage patients (median, 40.7 months vs 24.9 months; P < .001), and high-stage patients were 9.2 times more likely to progress (hazard ratio, 9.24; 95% confidence interval, 1.93-44.36). Among 30 patients with surgically resected stage IE disease, 8 with central lesions were treated via lobectomy and 22 with peripheral lesions were treated via lobectomy (n = 8) or limited resection (n = 14). One of these patients, with a central lesion, experienced disease recurrence. CONCLUSIONS Our findings suggest that the clinical course of low-stage pulmonary MALT lymphoma, for which the mainstay of treatment is surgical resection, might be indolent.

Abstract
An 8-year-old girl who had experienced intermittent cough and fever over a 3 year period, was admitted after experiencing a recurrence for one month. One year ago the patient experienced a recurrent oral mucosal ulcer. Physical examination showed vitiligo in the skin of the upper right back. Routine blood tests and immune function tests performed in other hospitals had shown normal results. Multiple lung CT scans showed pulmonary infection. The patient had recurrent fever and cough and persistent presence of some lesions after anti-infective therapy. The antitubercular therapy was ineffective. Routine blood tests after admission showed agranulocytosis. Gene detection was performed and she was diagnosed with dyskeratosis congenita caused by homozygous mutation in RTEL1. Patients with dyskeratosis congenita with RTEL1 gene mutation tend to develop pulmonary complications. Since RTEL1 gene sequence is highly variable with many mutation sites and patterns and can be inherited via autosomal dominant or recessive inheritance, this disease often has various clinical manifestations, which may lead to missed diagnosis or misdiagnosis. For children with unexplained recurrent pulmonary infection, examinations of the oral cavity, skin, and nails and toes should be taken and routine blood tests should be performed to exclude dyskeratosis congenita. There are no specific therapies for dyskeratosis congenita at present, and when bone marrow failure and pulmonary failure occur, hematopoietic stem cell transplantation and lung transplantation are the only therapies. Androgen and its derivatives are effective in some patients. Drugs targeting the telomere may be promising for patients with dyskeratosis congenita.

Abstract
Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a rare extranodal lymphoma with a 5-year survival rate of 80-95 %. There is no standard treatment strategy for pulmonary MALT lymphoma. In the present study, we performed a retrospective evaluation of systemic rituximab monotherapy (375 mg m(-2) day(-1), 4-8 cycles) as first-line treatment in patients with pulmonary MALT lymphoma. Of the eight patients enrolled, five achieved complete response, one achieved partial response, and two showed stable disease. Median progression-free survival was 66.0 months (range 9.7-87.2 months). Treatment was well tolerated and all patients were alive during the median follow-up period of 64.0 months. Rituximab monotherapy was efficacious in patients with pulmonary MALT lymphoma, demonstrating long-term disease stabilization and symptom reduction. Larger prospective studies are warranted to further assess the efficacy of rituximab monotherapy. In conclusion, rituximab monotherapy may be considered for first-line therapy in patients with pulmonary MALT lymphoma.

Abstract
Sjögren's syndrome (SS) is primarily defined by its impact on the oral and ocular system resulting in xerostomia and xerophthalmia. However, SS can also manifest throughout the respiratory system. Subclinical pulmonary involvement is common. Clinically significant involvement can result in a 4-fold increased risk of death. Thus, recognizing the many potential presentations of SS in the lung is critical in caring for patients with SS. Additionally, SS should be included in the differential diagnosis of a number of forms of interstitial lung disease.

Abstract
CONTEXT Diagnosis and classification of lymphomas are based on the morphologic, immunologic, and genetic features that the lesional cells share with their normal B and T lymphocyte counterparts. Primary pulmonary lymphomas account for 0.3% of primary lung neoplasms and less than 0.5% of all lymphomas. OBJECTIVE To describe and summarize the clinical and histopathologic features of the primary pulmonary lymphoma and secondary involvement of the lung by lymphoma. DATA SOURCES Peer-reviewed published literature and personal experience. CONCLUSIONS Diagnosis of clonal lymphoid proliferations in the lung has evolved owing to the greater utility of molecular and flow cytometric analysis of tissue. Further studies are needed to best define the clinical and prognostic features, as well as search for targeted therapy for these patients with rare neoplasms.

Abstract
A 72-year-old man presented with weight loss, fever, and malaise. Chest radiograph and CT revealed two large ill-defined masses in middle and left lower lobes. CT-guided biopsy of left lower lobe mass disclosed bronchus-associated lymphoid tissue (BALT) lymphoma. Middle lobe mass was considered second deposit in contralateral lung. The patient received chemotherapy for BALT. Followup CT disclosed regression of left lower lobe mass and stability of middle-lobe mass and of right paratracheal lymph nodes. CT-guided biopsy of middle-lobe mass revealed squamous cell lung carcinoma. Surgical biopsy of right paratracheal lymph nodes revealed malignancy. Disease was staged T3, N2, and M0. Combined chemotherapy for lung cancer and BALT lymphoma was initiated.

Abstract
We retrospectively analysed 16 cases of newly diagnosed pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma in the Japanese population. The disease was found on the basis of examination findings in 14 cases, and clinical manifestations in 2. According to the extensive staging procedure, four patients had concomitant gastric involvement. Primary treatment involved surgery alone in two patients; surgery followed by rituximab (R)-containing chemotherapy in two; R-containing chemotherapy alone in 11; and chemoradiotherapy without R in one. Over the median observation period of 28 months, disease progression was recorded in three patients, but all 16 patients were alive at the end of the observation period. One patient was treated with R alone and achieved partial remission; subsequent tentative surgery showed no evidence of residual lymphoma. It has been 72 months of progression-free survival after the diagnosis. Primary pulmonary MALT lymphoma exhibited an indolent clinical course. R has potential as a therapeutic agent in patients with pulmonary MALT lymphoma.

Abstract
Introduction Extranodal marginal B-cell lymphoma of bronchus-associated lymphoid tissue is a rare entity accounting for less than 1% of all lymphomas. We report a case of a low-grade bronchus-associated lymphoid tissue lymphoma stage IV with transformation to an aggressive large B-cell lymphoma. Case presentation A 59-year-old African-American man was incidentally found to have a bronchus-associated lymphoid tissue lymphoma involving the bilateral lower lobes of his lungs. In addition, bone marrow involvement was discovered. His course was indolent with only some mild respiratory symptoms. He received single agent treatment with rituximab. No evidence of progression was seen at the end of receiving this regimen. Two years after treatment our patient presented with B symptoms. Imaging now showed significant increase in the size of the lung masses with cavitation of the right lower lobe mass. A repeat transbronchial biopsy suggested transformation to an aggressive diffuse large B-cell lymphoma. Conclusion This case illustrates a rare bronchus-associated lymphoid tissue lymphoma stage IV with histologic transformation to an aggressive lymphoma. In addition, this rare case of transformation presented as a cavitary lesion.

Abstract
BACKGROUND AND OBJECTIVE As a rare disease, pulmonary marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (PMZL-MALT), is often misdiagnosed. The aim of this study is to summarize the clinical and pathological features of this disease and improve the awareness of doctors. METHODS Seven cases (female 5, male 2) diagnosed of PMZL-MALT in West China Hospital between November 2008 and November 2010, were analyzed retrospectively, including their symptoms, radiological findings, pathological examinations, treatment and prognosis. RESULTS The median age of the patients were 62 years old (range 34-79 years). Six patients suffered from cough and sputum. Pulmonary consolidation was the most frequent manifestation, leading a misdiagnosis of pneumonia with CT examinations. Pathological diagnosis was obtained via fiberoptic bronchoscopy in six patients and percutaneous pulmonary biopsy for the rest one. In the seven cases, immunohistochemical results showed CD20(+), CD79a(+), while CD3 epsilon(-), CD5(-), CyclinD1(-), CD10(-), Bcl-2(-) and CD30(-). Additionally, the expression of Ki-67 was below 10%. Further PCR analysis showed evidence of immunoglobulin heavy chain gene rearrangement in tissues from six subjects. Based on the disease location and patients' wishes, compared with two cases just receiving symptomatic treatments, the other five ones took in chemotherapies. CONCLUSION Since there were no specific clinical features for patients of PMZL-MALT, histopathological examination was the only effective means to confirm the diagnosis.

Abstract
BACKGROUND/AIM Bronchus-associated lymphoid tissue (BALT) lymphoma is a rare subtype of low grade marginal zone B cell lymphoma representing 10% of all MALT lymphomas. The purpose of this study was to analyze the outcome of this group of patients comparing prognostic parameters and therapy modalities. METHODS A total of eight patients with BALT lymphoma had diagnosed between January 1998-April 2008 at the Institute of Hematology, Clinical Center of Serbia, Belgrade, and they were included in this retrospective analysis. RESULTS Male/female ratio was 2/6, the median age was 64 years (range 37-67 years). Six patients had nonspecific respiratory symptoms and all of them had B symptoms. The patients were seronegative for HIV, HCV and HBsAg. Three patients had Sjogren's syndrome, rheumatoid arthritis and pulmonary tuberculosis, respectively. Seven patients were diagnosed by transbronchial biopsy and an open lung biopsy was done in one patient. Patohistological findings revealed lymphoma of marginal zone B cell lymphoma: CD20+/CD10-/CD5-/CyclinD1/CD23-/IgM- with Ki-67+< 20% of all cells. According to the Ferraro staging system, five patients had localized disease (CS I-IIE) and three had stage IVE; bulky tumor mass had 3 patients. All patients had Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1. Five patients received monochemotherapy with chlorambucil and 3 were treated with CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone). A complete response (CR) was achieved in 5 patients and a partial response (PR) in 3 of them, treated with chlorambucil monotherapy and CHOP regimen. All patients were alive during a median follow-up period of 49 months (range 6-110 months). Three patients relapsed after monochemotherapy into the other extranodal localization. They were treated with CHOP regimen and remained in stable PR. CONCLUSION. BALT lymphoma tends to be localised disease at the time of diagnosis, responds well to monochemotherapy with chlorambucil and has a favourable prognosis.

Abstract
Bronchus-associated lymphoid tissue (BALT) is a constitutive mucosal lymphoid tissue adjacent to major airways in some mammalian species, including rats and rabbits, but not humans or mice. A related tissue, inducible BALT (iBALT), is an ectopic lymphoid tissue that is formed upon inflammation or infection in both mice and humans and can be found throughout the lung. Both BALT and iBALT acquire antigens from the airways and initiate local immune responses and maintain memory cells in the lungs. Here, we discuss the development and function of BALT and iBALT in the context of pulmonary immunity to infectious agents, tumors, and allergens as well as autoimmunity and inflammatory diseases of the lung.
