Clinical study of chemotherapy-related cognitive impairment in patients with non-Hodgkin lymphoma

BACKGROUND Chemotherapy for malignant tumors can cause brain changes and cognitive impairment,leading to chemotherapy-induced cognitive impairment(CICI).Current research on CICI has focused on breast cancer and Hodgkin’s lymphoma.Whether patients with non-Hodgkin’s lymphoma(NHL)undergoing chemo-therapy have cognitive impairment has not been fully investigated.therapy have cognitive impairment has not been fully investigated.AIM To investigate whether NHL patients undergoing chemotherapy had cognitive impairments.METHODS The study included 100 NHL patients who were required to complete a compre-hensive psychological scale including the Brief Psychiatric Examination Scale(MMSE)at two time points:before chemotherapy and within 2 wk of two chemo-therapy courses.A language proficiency test(VFT),Symbol Number Pattern Test(SDMT),Clock Drawing Test(CDT),Abbreviated Daily Cognition Scale(ECog-12),Prospective and Retrospective Memory Questionnaire,and Karnofsky Perfor-mance Status were used to assess cognitive changes before and after chemo-therapy.RESULTS The VFT scores for before treatment(BT)and after treatment(AT)groups were 45.20±15.62,and 42.30±17.53,respectively(t-2.16,P<0.05).The CDT scores were 8(3.5-9.25)for BT and 7(2.5-9)for AT groups(Z-2.1,P<0.05).Retrospective memory scores were 13.5(9-17)for BT and 15(13-18)for AT(Z-3.7,P<0.01).The prospective memory scores were 12.63±3.61 for BT and 14.43±4.32 for AT groups(t-4.97,P<0.01).The ECog-12 scores were 1.71(1.25-2.08)for BT and 1.79(1.42-2.08)for AT groups(Z-2.84,P<0.01).The SDMT and MMSE values did not show a significant difference between BT and AT groups.CONCLUSION Compared to the AT group,the BT group showed impaired language,memory,and subjective cognition,but objec-tive cognition and execution were not significantly affected.

Primary Non-Hodgkin’s Malignant Lymphoma of the Uterus at the Reference Hospital of Maradi/Niger: A Case Report

Malignant non-Hodgkins lymphoma (MHNL) of the uterus is uncommon. We report a case diagnosed on the basis of histologic and immunohistochemical studies of a hysterectomy specimen induced by a very painful pelvic mass in a 50-year-old patient with no previous history of the disease. It was classified as Ann Arbor IV Bb after imaging, given the medullary infiltration and signs of clinical and biological evolutivity: the patient had received two courses of chemotherapy, CHOP protocol. She died 23 days after the second treatment due to a hypertensive crisis.

Cost-Minimization and Budget Impact Analysis of Rituximab SC VS Rituximab IV for Non-Hodgkin’s Lymphoma (NHLs) in Greece

Background: Non-Hodgkin’s lymphoma (NHLs) is a prevalent type of cancer for which Intravenous (IV) Rituximab is a widely used treatment option. Nevertheless, IV infusions can lead to intense resource use and, subsequently, costs. Given that a subcutaneous (SC) therapeutically equivalent formulation of the drug is currently available, this study aimed to examine the potential clinical and economic value of the introduction of the SC formulation for the Greek healthcare setting. Methods: A cost-minimization and budget-impact analysis contributed to comparing staff, patient time and resource utilization and estimating the clinical effects and associated costs in the IV and SC administration. A questionnaire-based survey was used to provide data regarding the local treatment patterns and the resource use associated with each treatment in the Greek NHS. The analysis followed the third-party payer perspective, and cost data relevant to personnel salaries, pharmaceuticals and resource utilization were obtained from official government sources. Results: SC administration was associated with time savings in activities such as pre-medication administration (3 minutes saved with the SC use), monitoring during infusion (12 minutes for physicians and 3 minutes for nurses) as well as time-savings in the preparation of the drugs, the actual dispensing process and the post-injecting monitoring processes. A significant decrease was observed in the nursing and chair time (57% and 90% per case, respectively) and a higher level of services could be secured in terms of hospital capacity with the SC use. SC administration was found to generate budget savings of 618,708€ per 1000 patients/3 years over the full course of treatment. Conclusions: Switching IV to SC administration, as demonstrated in the case of Rituximab for NHLs in Greece, can reduce staff time and administration costs, improve the capacity of the system and, possibly, improve resource allocation in the healthcare system.

Clinical characteristics for 112 cases with non-Hodgkin’s lymphoma

Objective： To study clinical characteristics of non-Hodgkin＇s lymphoma （NHL） in order to diagnose and treat early and improve prognosis. Methods： 112 cases with NHL were pathologically diagnosed and treated in 1992-2005. Results： Among all cases, 30 were not treated previously, 79 were involved in peripheral lymph nodes, 55 deep lymph nodes, 18 Waldeyer＇s ring, 25 respiratory system, 26 digestive system, 26 spleen, 13 bone, 13 skin and subcutaneous, 4 urinogenital system, 13 other sites. Among 30 previously untreated patients, there were 4 staged 1, 3 IE1 5 Ⅱ, 1 ⅡE, 9 Ⅲ, 1 Ⅲs and 7 IV. Among 82 patients with prior treatment, 29 were involved in lymph nodes only, 53 involved in different organs and tissues. In our series, there were 38 cases and 74 cases belonged to subtype A and subtype B respectively. Conclusion： The enlargement of peripheral lymph nodes is main clinical characteristic in NHL, but lesions also involve different organs and tissues. The diagnosis of NHL depends upon pathological examination.

The expressions of CD147 and MMP-9 in non-Hodgkin's lymphoma cells and the relation to prognosis

Objective： The aim of this study was to investigate the expression of CD147 and matrix metalioprpteinsae 9 （MMP-9） in children with non-Hodgkin＇s lymphoma （NHL） and the relations between expressions of CD147 ＆ MMP-9 and the clinical indexes. Methods： Specimens excised from NHL patients were prepared. Expression of CD147 and MMP-9 were tested by SABC immunohistochemistry and its correlation to clinical results were analyzed in this report. Results： The positive rate of CD147 expression was 73% （45/62）, and that of MMP-9 expression was 81% （50/62）. There was a positive correlation between CD147 and MMP-9 expressions. CD147 expression intensity was linked to clinical myelo-infiltration, tumor size, LDH value, and clinical staging （P 〈 0.05）, rather than children age, gender, or immune typing （P 〉 0.05）; MMP-9 expression intensity was linked to myelo-infiltration, and clinical staging （P 〈 0.05）, rather than age, gender, immune typing, tumor size, or LDH value （P 〉 0.05）. Five-year survival rates were 78% （22/28） and 45% （15/34） in CD147 （-）-（＋） and （＋＋）-（＋＋＋） cases respectively, and those were 84% （21/25） and 43% （16/37） in MMP-9 （-）-（＋） and （＋＋）-（＋＋＋） cases respectively, the difference was significant. Conclusion： The elevated expression of CD147 and/or MMP-9 correlates with a poor clinical outcome in patients with NHL.

Primary early-stage intestinal and colonic non-Hodgkin's lymphoma: Clinical features, management, and outcome of 37 patients

AIM： To analyze the clinical features, management, and outcome of treatment of patients with primary intestinal and colonic non-Hodgkin＇s lymphoma （PICL）. METHODS： A retrospective study was performed in 37 patients with early-stage PICL who were treated in our hospital from 1958 to 1998. Their clinical features, management, and outcome were assessed. Prognostic factors for survival were analyzed by univariate analysis using the Kaplan-Meier product-limit method and log-rank test. RESULTS： Twenty-five patients presented with Ann Arbor stage Ⅰ PICL and 12 with Ann Arbor stage Ⅱ PICL. Thirty-five patients underwent surgery （including 31 with complete resection）, 22 received postoperative chemotherapy or radiotherapy or both. Two patients with rectal tumors underwent biopsy and chemotherapy with or without radiotherapy. The 5- and 10-year overall survival （OS） rates were 51.9% and 44.5%. The corresponding diseasefree survival （DIS） rates were 42.4% and 37.7%. In univariate analysis, multiple-modality treatment was associated with a better DFS rate compared to single treatment （P= 0.001）. While age, tumor size, tumor site, stage, histology, or extent of surgery were not associated with OS and DFS, use of adjuvant chemotherapy significantly improved DFS （P = 0.031） for the 31 patients who underwent complete resection. Additional radiotherapy combined with chemotherapy led to a longer survival than chemotherapy alone in six patients with gross residual disease after surgery or biopsy.CONCLUSION： Combined surgery and chemotherapy is recommended for treatment of patients with PICL, Additional radiotherapy is needed to improve the outcome of patients who have gross residual disease after surgery.

A case of primary isolated non-Hodgkin’s lymphoma of the esophagus in an immunocompetent patient

Primary non-Hodgkin’s lymphoma of the esophagus is a rare disease.A case of primary isolated nonHodgkin’s lymphoma of the esophagus in a 77-yearold man without acquired immunodeficiency syndrome is presented.We describe the clinical features and the imaging findings(barium swallow,endoscopic ultrasonography and CT)of a biopsy proven B-cell lymphoma with diffuse transmural involvement of the esophagus wall,which was discovered incidentally.We also briefly review the literature.

Primary gastric non-Hodgkin lymphomas:Recent advances regarding disease pathogenesis and treatment

Primary gastric lymphomas(PGLs)are distinct lymphoproliferative neoplasms described as heterogeneous entities clinically and molecularly.Their main histological types are diffuse large B-cell lymphoma(DLBCL)or mucosaassociated lymphoma tissue.PGL has been one of the main fields of clinical research of our group in recent years.Although gastric DLBCLs are frequent,sufficient data to guide optimal care are scarce.Until today,a multidisciplinary approach has been applied,including chemotherapy,surgery,radiotherapy or a combination of these treatments.In this minireview article,we provide an overview of the clinical manifestations,diagnosis and staging of these diseases,along with their molecular pathogenesis and the most important related clinical published series.We then discuss the scientific gaps,perils and pitfalls that exist regarding the aforementioned studies,in parallel with the unmet need for future research and comment on the proper methodology for such retrospective studies.Aiming to fill this gap,we retrospectively evaluated the trends in clinical presentation,management and outcome among 165 patients with DLBCL PGL who were seen in our institutions in 1980-2014.The study cohort was divided into two subgroups,comparing the main 2 therapeutic options[cyclophosphamide doxorubicin vincristine prednisone(CHOP)vs rituximab-CHOP(R-CHOP)].A better outcome with immunochemotherapy(R-CHOP)was observed.In the next 2 mo,we will present the update of our study with the same basic conclusion.

Positron emission tomography/computerized tomography in the evaluation of primary non-Hodgkin's lymphoma of prostate

Primary malignant lymphoma of the prostate is exceedingly rare.Here we report a case of a 65-year-old man who presented with increased urinary frequency,urinary urgency,and urinary incontinence for two years.Benign prostatic hypertrophy was suspected at primary impression.Ultrasound revealed a hypoechoic lesion of the prostate.The total serum prostate-specific antigen was within normal range.Positron emission tomography/computerized tomography(PET/CT)showed a hypermetabolic prostatic lesion.Prostate biopsy was consistent with a non-germinal center diffuse large B cell lymphoma.There was complete remission of the prostatic lesion following six cycles of chemotherapy as shown on the second PET/CT imaging.18F-fluoro-deoxy glucose PET/CT is not only a complement to conventional imaging,but also plays a significant role in the diagnosis and evaluation of treatment response of prostatic lymphoma.

Molecular markers(PECAM-1,ICAM-3,HLA-DR)determine prognosis in primary non-Hodgkin's gastric lymphoma patients

AIM： To investigate the prognostic significance of PECAM-1, ICAM-3 and HLA-DR antigens in patients with primary non-Hodgkin＇s gastric lymphoma. METHODS： We immunohistochemically studied PECAM-1, ICAM-3 and HLA-DR antigen expression in 36 B-cell MALT-type primary gastric lymphoma patients. Ten non-malignant and ten healthy gastric tissue specimens were used as controls. Clinicopathological and survival data were correlated with the staining results. RESULTS： HLA-DR antigen expression was detected in 33 gastric lymphoma patients （91.7%） and 6 nonmalignant patients （54.5%）. PECAM-1 stained tumor cells of 10 patients （27.8%）, endothelial cells of 9 patients （25%） and inflammatory infiltrate of 4 patients （40%） with benign gastric disease. ICAM-3 expression was observed on the tumor cells of 17 patients （47.2%）, while 5 non-malignant patients （50%） were stained positive as well. None of the healthy controls was stained for any of the genes studied. In the multivariate analysis, HLA-DR antigen and PECAM-1 were proved to be statistically significant independent prognostic factors associated with a favourable and an unfavourable prognosis respectively （P= 0.009 and P= 0.003）. In the univariate analysis, PECAM-1（＋）/ICAM-3（-） and HLA-DR（-）/ICAM-3（-） patients exhibited a significantly decreased overall survival compared to those with the exactly opposite gene expression patterns （P=0.0041 and P= 0.0091, respectively）. Those patients who were HLA-DR（＋ ）/ICAM-3（＋ ）/PECAM-I（-） （n = 8） had a significantly higher survival rate compared to the rest of the group （n = 24） （P= 0.0289）. CONCLUSION： PECAM-1, ICAM-3 and HLA-DR are representative markers of tumor expansion potential and host immune surveillance respectively. Their combined use may help us to identify high-risk patients who could benefit from more aggressive therapeutic protocols.

Pediatric-type follicular lymphoma in a Crohn’s disease patient receiving anti-α4β7-integrin therapy:A case report

BACKGROUND Patients with autoimmune conditions receiving immunosuppressants are at risk of non-Hodgkin lymphomas(NHL).Vedolizumab(anti-α4β7-integrin antibody),a treatment-of-choice for Crohn’s disease(CD),reduces inflammatory lymphocyte trafficking into the intestinal mucosa.This effect is believed to be confined to the colon.CASE SUMMARY We report the case of a CD patient on vedolizumab for five years who developed pediatric-type follicular lymphoma.Work-up prior to therapy revealed a reduction in circulating T-lymphocytes and their suppressed response to mitogens.Rituximab,cyclophosphamide,vincristine,and prednisone chemoimmunotherapy resulted in durable lymphoma remission,and vedolizumab treatment was continued.While the patient’s T-lymphocyte population and immunoglobulin production recovered,the T-lymphocyte mitogen response remained suppressed.CONCLUSION This patient’s NHL may be linked to receiving anti-α4β7 therapy.Further research could be beneficial to determine if proactive surveillance for NHL and other systemic diseases is indicated in patients on vedolizumab.

Simultaneous occurrence of a hepatocellular carcinoma and a hepatic non-Hodgkin's lymphoma infi ltration

To investigate the simultaneous occurrence of hepatocellular carcinoma and non-Hodgkin's lymphoma, we report the case of a 70 year old patient with a primary diagnosis of non-Hodgkin's lymphoma in 2002. In a routine follow up investigation of his chronic lymphocytic leukemia a newly detected mass in the Couinaud's segments 2 and 3 was found. No hepatitis C virus or hepatitis B virus infection or cirrhosis was evident. After laparoscopic segmentectomy the histological examination revealed a hepatocellular carcinoma. While the relation between liver parenchyma damages and hepatocellular carcinoma or non-Hodgkin's lymphoma is well known, only a few publications have focused on the coexistence of hepatocellular carcinoma and non-Hodgkin's lymphoma. With this case we demonstrate the coexistence of these diseases without having a pre- damaged liver parenchyma.

Hepatitis viruses and non-Hodgkin's lymphoma: A review

Non-Hodgkin's lymphoma(NHL) is among the haematological malignancies with high prevalence worldwide, causing estimated 355 900 new cases and 191 400 deaths in 2008. High prevalence of NHL is documented in economically more developed areas while low prevalence is observed in less developed areas of the globe. A wide array of environmental factors have been reported to be either directly involved or in modifying the risk of NHL development. In addition to these factors, a number of infectious agents, chiefly viruses have also been implicated in the development of NHL. This article reviews the available literature to discuss the role of hepatitis viruses in NHL development, possible mechanisms of lymphomagenesis and also identify the areas in which further research is required to better understand this disease. A brief discussion on the clinical aspects such as classification, staging, treatment approaches have also been included in this article.

The expression of cyclooxygenase-2 （COX-2） and p16 in non-Hodgkin＇s lymphomas and its clinical significance

Objective： To investigate the expression of cyclooxygenase-2 （COX-2） and p16 proteins in non-Hodgkin＇s lymphomas （NHL） and their relationship with the genesis and progress of it. Methods： The expression of COX-2 and p16 protein were studied in the lymph nodes tissue from 60 NHL patients and 10 control patients with non-malignant diseases by flow cytometry. Results： Positive rate of COX-2 protein expression in NHL tissues （63.3%, 38/60） was higher than that in normal lymphaden tissues （0, 0/10）. The difference was significant between the two groups （P 〈 0.01）. Expression of COX-2 protein was related with the clinical stage of NHL. In stage Ⅰ ＋ Ⅱ patients, it was significantly lower （35.0% ± 54.6%） than that in stage Ⅲ ＋ Ⅳ patients （84.6% ±87.5%） （P 〈 0.01）. In different sex, age, tumor malignant degree, IPI grade, extranodal involvement and B symptoms groups, the differences of COX-2 expression were not statistically significant （P 〉 0.05）. Positive rate of p16 protein expression （41.7%, 25/60） in NHL＇ was statistically lower than that in normal lymphomas （100%, 10/10） （P 〈 0.01）. Expression of p16 protein was related to malignant degree of NHL. The positive rates of p16 protein in low malignant degree tissues （64.7%, 11/17） was higher than that in high malignant degree tissues （14.3%, 2/14） （P 〈 0.05）. Positive rates of p16 protein of NHL tissues in different sex, age, IPI grade, extranodal involvement, clinical stages and B symptoms were not statistically significant （P 〉 0.05）. The p16 protein expression in COX-2 positive patients was 47.4% （18/38）, and in negative patients it was 31.8% （7/22）. There was no statistically difference between them （P 〉 0.05）. Correlation analysis revealed there was no correlation between expression of COX-2 and p16 protein. Conclusion： Both COX-2 and p16 protein may all have relationship with the genesis and progress of NHL. The expression of COX-2 protein in NHL may be a poor prognostic indicator. COX-2 and p16 protein probably have different mechanisms in the genesis and progress of NHL. Their relationship is firstly put forward in this article and needed further studying.

The prognostic value of programmed cell death ligand 1expression in non-Hodgkin lymphoma:a meta-analysis

Objective: Although the prognostic value of programmed cell death-ligand 1(PD-L1) expression in non-Hodgkin lymphoma(NHL) has been evaluated in many studies, the results remain controversial. To investigate the prognostic role of PD-L1 expression and the association between PD-L1 expression and clinicopathological features of NHL, we performed a meta-analysis.Methods: The Pub Med, EMBASE, and Cochrane Library databases were searched up to November 30, 2017. The hazard ratio(HR), 95% confidence interval(CI), and odds ratios(OR) with 95% CIs were combined to evaluate the association of PD-L1 expression with overall survival(OS) and clinicopathological features. Review manager 5.3 and STATA 12.0 were used in this meta-analysis.Results: A total of 2,005 patients across nine studies were enrolled in our meta-analysis, and the pooled results showed that high PD-L1 expression was associated with a poor prognosis(HR=2.04, 95% CI: 1.18–3.54, P=0.01). In the subgroup analysis according to histology types, pooled results demonstrated that an increased PD-L1 expression was an unfavorable prognostic factor for diffuse large B-cell lymphoma(HR=1.92, 95% CI: 1.06–3.48, P=0.03) but not for natural killer/T-cell lymphoma(HR=2.41, 95%CI: 0.47–12.22, P=0.29). Pooled ORs indicated that PD-L1 expression was higher in NHL with international prognostic indices of≥3. However, PD-L1 expression had no correlation with gender, age, disease stage, lactate dehydrogenase level, B symptoms, and germinal center B-cell-like lymphoma.Conclusions: High PD-L1 expression was a poor prognostic biomarker in patients with NHL. Because of our limited sample size,high-quality studies with larger sample sizes are needed to validate our results.

Non-Hodgkin's Lymphoma Primarily Presenting with Fanconi Syndrome and Acute Kidney Injury

KIDNEY involvement is common in non-Hodgkin＇s lymphoma （NHL） with incidence up to 30%-40% in autopsy studies. However, it us- ually occurs late in the course of the diseaseand is clinically silent. Clinically overt renal disease including acute kidney injury （AKI） as its primary manifestation is rarely reported, moreover, Fanconi syndrome （FS） is extremely rare as the main manifestation in NHL. In this report, we presented a case of NHL primarily presenting with FS and AKI due to diffuse interstitial infiltration of NHL cells and emphasized the important role of renal biopsy, especially renal immunohistochemical analysis in the diagnosis of renal diffuse lymphoma.

HCV infection, B-cell non-Hodgkin's lymphoma and immunochemotherapy: Evidence and open questions

There is plenty of data confirming that hepatitis C virus (HCV) infection is a predisposing factor for a B-cell non-Hodgkin's lymphoma (B-NHL) outbreak, while relatively few reports have addressed the role of HCV in affecting B-NHL patients' outcome. HCV infection may influence the short-term outcome of B-NHL because of the emergence of severe hepatic toxicity (HT) during immunochemotherapy. Furthermore, the long term outcome of HCV-related liver disease and patients' quality of life will possibly be affected by Rituximab maintenance, multiple-lines of toxicity during chemotherapy and hematopoietic stem cell transplantation. In this review, data dealing with aggressive and low-grade B-NHL were separately analyzed. The few retrospective papers reporting on aggressive B-NHL patients showed that HCV infection is a risk factor for the outbreak of severe HT during treatment. This adverse event not infrequently leads to the reduction of treatment density and intensity. Existing papers report that low-grade B-NHL patients with HCV infection may have a more widespread disease, more frequent relapses or a lower ORR compared to HCV-negative patients. Notwithstanding, there is no statistical evidence that the prognosis of HCV-positive patients is inferior to that of HCV-negative subjects. HCV-positive prospective studies and longer follow-up are necessary to ascertain if HCV-positive B-NHL patients have inferior outcomes and if there are long term sequels of immunochemotherapies on the progression of liver disease.

Preliminary outcome of rituximab-containing salvage regimens on relapsed or refractory B-cell non-Hodgkin’s lymphoma: single institution experience

Objective： The prognosis of relapsed or refractory B-cell lymphoma is poor, with a short-term survival after conventional second-line chemotherapy, Rituximab, a chimeric anti-CD20 antigen, in combination with CHOP or CHOP-like chemotherapy may improve both disease free survival （DFS） and overall survival （OS） of naive patients, but its role in the second-line therapy for relapsed non-Hodgkin＇s Lymphoma （NHL） remains to be defined, This study aimed to evaluate the efficacy of rituximab-containing salvage regimens for relapsed or refractory NHL, and observe the toxicities. Methods： The clinical data of 54 patients, who were with relapsed or refractory NHL and treated in the Cancer Center of Sun Yat-sen University, were analyzed retrospectively, Of the 54 patients, 29 were man, 25 were women, with a median age of 52.5 years old （range 18 to 75）; 50 patients （92.6%） scored 0-1 for the ECOG performance status; for second-line international prognostic index （slPI）, 21 （38.9%） scored 0-1,30 （55.6%） scored 2 to 3, and 3 （5.6%） scored 4-5; 40 cases were diffuse large B-cell lymphoma （DLBCL）, accounting for 74.1% of all subtypes, Rituximab was administered intravenously at a dose of 375 mg/m^2 at the day before each chemotherapy cycle, The second or third-line salvage regimens included EPOCH, CHOP, DHAP, DICE, IVAC, IMVP-16 and FND, Results： Of the 54 patients, 49 received retuximab-containing salvage regimens, The objective response rate of the 45 evaluable cases was 68,8%, with a complete remission （CR） rate of 37.7%; 3 patients achieved CR after radiotherapy following rituximab-based regimens and 3 achieved CR after autologous hematopoietic stem cell transplantation, The most frequent adverse events were leucopenia, nausea and alopecia. The addition of rituximab to chemotherapy only elevated the occurrence of mild infusion-related reactions, such as chills, fever and pruritus. The median follow-up time was 18 months （range 2-86 months）; 5 patients were lost, 24 were dead （23 died of lymphoma, and 1 died of severe hepatitis）, the other patients remained alive. The median survival time was 32 months （range 2-86 months, 95% confidential interval 16-48 months）. The 1-, 2- and 3-year OS rates were 70.6%, 53,6% and 41,5%, respectively, The median TTP was 6 months （range 0-52 months）, The median PFS was 10 months （range 0-47 months, 95% CI 0-26 months）, The 1- and 2-year PFS were 49,3% and 41,3%. Conclusion： Rituximab-containing salvage regimens are effective and well tolerated therapy for patients with relapsed or refractory B-cell NHL, even those were extensively treated.

Ultrasound features of primary non-Hodgkin’s lymphoma of the palatine tonsil:A case report

BACKGROUND Lymphomas are the second most common malignancy of the head and neck.In this region,the vast majority of extranodal lymphomas are located in the palatine tonsil,accounting for about 51%.Tonsillar lymphomas are aggressive tumors with intermediate-or high-grade histology.We here report a case of primary non-Hodgkin’s lymphoma of the palatine tonsil and analyze its ultrasound features.CASE SUMMARY A 40-year-old man presented with right palatine tonsil swelling for 2 mo after a cold,accompanied by dysphagia,snoring,and suffocation.He had no sore throat,fever,or history of upper respiratory tract infection or tuberculosis.The patient was generally in good health and denied other diseases.He was diagnosed with acute tonsillitis initially and treated with antibiotics for 7 d.However,there was no improvement with the treatment.Tonsil biopsy and ultrasound-guided biopsy of the biggest lymph node of the right neck showed the typical pathology of non-Hodgkin lymphoma.CONCLUSION Primary lymphoma of the tonsils is rare,and its diagnosis is challenging.Ul-trasound is a useful modality in diagnosing oropharyngeal diseases,and can clearly show the features of this tumor,but the final diagnosis should be estab-lished by histology.

Non Hodgkin’s Lymphoma with Right Atrial Intra Cardiac Metastases

Background: Diffuse Large B-Cell Lymphoma (DLBCL) is the most variant of Non-Hodgkin’s Lymphoma (NHL) and also the most common variant with secondary intracardiac masses. Case summary: 7 years old child presented to emergency with acute decompensated cardiac failure, ascites and tender hepatomegaly. 2D echo evaluation was suggestive of large intracardiac mass in the right atrium almost completely obstructing Tricuspid valve orifice, gross pericardial effusion and dilated Inferior Vena Cava (IVC). Emergency tumor excision surgery was performed which revealed 4 × 4 cm pinkish firm mass arising from anterior Tricuspid annulus which was completely excised. Child was extubated on postoperative day (POD) 0 and was on minimal inotropic support. Ascites reduced significantly on POD1 allowing abdominal palpation which revealed a mass in the epigastric region. This prompted evaluation by pediatrician and oncology workup suggestive of increased 18-Flouro Deoxy Glucose (18-FDG) uptake in the mediastinum, abdomen, bilateral proximal thighs, all mediastinal lymph nodal stations, bilateral lung hilar stations 10R, 10L involving all encasing the heart and great vessels with pleural deposits, Celiac trunk, superior Mesenteric Artery (SMA), Portal vein, IVC and abdominal aorta. Histo pathology Examination (HPE) and Immuno Histo Chemistry (IHC) of intracardiac mass revealed DLBCL which is metastatic in nature. Chemotherapy was started as per (French American British Lymphomes Malins B) FAB LMB-96 protocol with the child currently in the Induction phase having poor prognosis and less survival interval. Conclusion: Surgery can be considered a treatment option for metastatic intracardiac masses during emergency scenarios like cardiogenic shock to relieve obstruction along the pathway of blood flow in the heart even though we may not be able to completely excise the tumor surgically.
