The difference between lymphoma type and leukemia type of adult T-cell leukemia (ATL) were analysed with 102 Japanese patients all positive for human T-cell leukemia virus type I (HTLV-I) antibody. They were classified into three groups on findings at first medical examination: lymphoma type cases, leukemia type cases, and mixed type (leukemia type plus lymphadeno-pathy) cases. Lymphoma type patients had several or more enlarged lymph nodes the largest of which was greater than 1 cm in diameter and with practically no abnormal lymphocytes (ATL. cells), which are characteristic of ATL, in the peripheral blood. Leukemia type patients had 10% or more ATL cells in the peripheral blood and had no detectablle lymphadenopathy Lymphoma type patients often complained of detectable lymphadenopathy, while leukemia type patients complained frequently of general fatigue and skin eruption. Mixed type patients more frequently had signs and symptoms which were characteristic of both types: lymphadenopathy and 10% or more ATL cells in the peripheral blood. Mixed type: ATL had a poorer prognosis than either lymphoma type or leukemia type. The median survival time was 3 months for mixed type patients, 10.5 months for lymphoma type patients, and 13.5 months for leukemia type patients. Complications and causes of death have also been touched upon. Clinicians are thus advised to consider ATL patients separately according to their clinical manifestations.  相似文献

A 55 year old man presented with clinical signs and symptoms of subacute pancreatitis of unknown aetiology. Two weeks later, inguinal lymphadenopathy developed and a lymph node biopsy revealed a B cell immunoblastic lymphoma. Computerized tomography showed enlargement of the pancreas and immaging features consistent with pancreatitis. Administration of VACOP-B combination chemotherapy achieved complete resolution of the pancreatic mass and the enlarged lymph nodes. We consider this patient to have had lymphoma associated pancreatitis. This case represents a rare clinical presentation of lymphoma suggesting an alternative aetiology of subacute pancreatitis in some cases.  相似文献

BackgroundIdentification of positive lymph nodes in colon cancer can significantly impact treatment. Few studies have examined the role of lymph node size in staging and prognosis. This study evaluated the relationship between lymph node size and lymph node metastases in right-sided colon cancer.MethodsRetrospective chart review was performed for patients undergoing colectomy for right-sided colon cancer from 2015 to 2020 across a single multi-hospital health system. Patients under age 18 or who did not have invasive adenocarcinoma upon pathological examination were excluded. Primary endpoints assessed lymph node size and lymph node metastases. 572 patients were stratified by lymph node size; lymph nodes ≥5 mm (n = 308) were characterized as enlarged.ResultsAll surgical specimens examined had adequate number of lymph nodes for staging. 33.9% of all specimens examined contained lymph node metastases. Patients with enlarged lymph nodes were significantly more likely to have lymph node metastases than those with normal-sized lymph nodes (p < 0.001). Enlarged lymph nodes were associated with advanced nodal staging.ConclusionsPatients with enlarged nodes were significantly more likely to have lymph node metastases than those with normal-sized lymph nodes. Further research to analyze these enlarged lymph nodes on radiologic imaging is warranted to determine the role of radiographic assessment of lymph node size during pre-operative staging.  相似文献

Cervical metastases from an occult primary site   总被引:1,自引:0,他引:1  
Less than 5% of patients with metastatic cervical carcinoma will not have a detectable primary site despite a proper work-up. Recent aids for these diagnostic problems include fine needle aspiration and immunohistochemical panels to differentiate undifferentiated carcinoma from melanoma and/or lymphoma. CT scanning can suggest areas in the upper aerodigestive tract for biopsy and can be helpful in suggesting the pathology of the enlarged lymph nodes. EBV titers are often elevated when a nasopharyngeal carcinoma is small. Aggressive treatment of the occult primary patient with metastatic melanoma, thyroid cancer, and metastatic cancer presumed to arise from the skin of the head and neck or the mucous membranes of the upper aerodigestive tract is indicated as long-term survival is often achieved.  相似文献

BACKGROUND: Mucosa-associated lymphoid tissue (MALT) lymphomas are a distinct subgroup of non-Hodgkin's lymphomas with preferable localization in the gastrointestinal tract. PATIENTS AND METHODS We describe the unusual case of a 48-year-old female patient, who was diagnosed with simultaneous MALT lymphoma of both breasts. Cervical, axillary and retroperitoneal lymph nodes were slightly enlarged, indicating an infiltration by the lymphoma. In her medical history the patient suffered from Hashimoto's thyroiditis. After 6 cycles of chemotherapy with CHOP regimen, the patient achieved complete remission. CONCLUSION: To our knowledge, this is the first case describing a patient with MALT lymphoma of the breast and a history of Hashimoto's thyroiditis. As patients suffering from autoimmune disorders, especially Sj?gren's syndrome and Hashimoto's thyroiditis, are at a higher risk to develop B-cell lymphoma, we assume that Hashimoto's thyroiditis favored development of MALT lymphoma in our patient.  相似文献

BACKGROUND: Despite documented superiority of integrated positron emission tomography-computerized tomography (PET-CT) over computerized tomography (CT) in lymph node staging in non-small cell lung cancer, little is known about the sensitivity, specificity and accuracy of integrated PET-CT among enlarged lymph nodes. We sought to assess if PET-CT is uniformly accurate among enlarged and non-enlarged lymph nodes. METHODS: A retrospective review of 206 consecutive patients with histologically proven non-small cell lung cancer who underwent resection and/or mediastinoscopy in our centre over 30 months period was carried out. All these patients had pre-operative staging with integrated PET-CT as an adjunct to chest CT prior to resection and/or mediastinoscopy. Diabetic patients (BM>or=8.0 mmol/l) and those who received neo-adjuvant chemotherapy were excluded. The pathological results of all these cases were reviewed and correlated with those on CT and integrated PET-CT. RESULTS: The sensitivity, specificity, accuracy, positive and negative predictive values were higher in integrated PET-CT than CT alone in all lymph nodes, whether N1 or N2. When lymph nodes were stratified by size, the sensitivity of PET-CT was significantly higher among enlarged (>1cm) than non-enlarged (1cm) should be with caution as the specificity of PET-CT is lower and its ability to detect truly negative nodes become reduced. NSCLC patients with enlarged nodes by CT criteria who are PET-CT negative may require cervical mediastinoscopy to rule out metastatic spread to these nodes. Prospective studies are warranted.  相似文献

Introduction: To evaluate the frequency of enlarged hilar or mediastinal lymph nodes in patients suffering from chronic obstructive pulmonary disease (COPD). Methods: In a retrospective study, 89 patients with proven COPD were analysed. Exclusion criteria were history of malignant disease or clinical evidence of pneumonia. Prevalence, size, and localisation of enlarged lymph nodes were assessed by multi-slice computed tomography (MSCT) and correlated with the clinical stages following the GOLD classification as well as the MSCT findings of bronchitis and emphysema. Results: 44/89 (49%) of our patients showed enlarged lymph nodes. Lymph node enlargement was more often seen in the mediastinum (48%) than the hilar region (20%). The most common localisation of enlarged mediastinal lymph nodes was the regional station 7 following the ATS mapping (infracarinal). Patients with a stage I following the GOLD classification showed enlarged lymph nodes in 49% (18/37), stage II in 46% (12/26), stage III in 58% (7/12) and stage IV in 50% (7/14). These findings did not differ significantly (P > 0.05). Severe airway wall thickening (42/89) was significantly more often associated with an increase of nodal enlargement (64%) (P < 0.05). Conclusion: The present study demonstrates that enlarged hilar and mediastinal lymph nodes may occur in a rather high percentage of patients suffering from COPD, especially in those with the MSCT finding of severe bronchitis.  相似文献

The diagnosis of malignant lymphoma presenting as an initial splenic manifestation may go unrecognized as such when peripheral lymph nodes are not enlarged and when results of bone marrow biopsies are negative. Tissues from 49 patients, ranging in age from 15 to 78 years, in whom the original diagnosis of malignant lymphoma and related conditions was made at splenectomy, were classified as: diffuse small lymphocytic (20), diffuse large cell (11), diffuse small cleaved (5), diffuse large cell, immunoblastic (5), follicular small cleaved cell (3), and follicular mixed small cell and large cell (2). Two additional spleens, diagnosed as acute blastic leukemia, were initially confused with malignant non-Hodgkin's lymphoma by light microscopy. One patient presented with Hodgkin's disease confined to the spleen. For the non-Hodgkin's lymphoma group, parameters of age, sex, splenic weight (range, 226-4000 g), lymph node, bone marrow, or liver involvement did not adversely influence prognosis. Abdominal lymph nodes were positive in 31 of 37 patients having splenic hilar and/or abdominal lymph nodes available for review. Of 29 patients with adequate follow-up, 7 died of disease, 5 were free of disease at 3 years, 2 were free of disease at 5 years, 2 were alive with disease at 3 years, 4 were alive with disease at 5 years, and 9 died from second malignancies, unknown, or unrelated causes. Six of the 7 patients who died of lymphoma were classified as large cell (four diffuse large cell and two diffuse large cell, immunoblastic), with a mean 2-year survival. One patient died of leukemia. Those lymphomas classified as low grade behaved in an indolent fashion. The morphologic diversity of these cases emphasizes the need for the initial recognition and correct classification of lymphomas which present in the spleen, since survival is best determined according to histologic type.  相似文献

BACKGROUND AND PURPOSE: Many observations on potential inadequate coverage of tumour volume at risk in advanced cervical cancer (CC) when conventional radiation fields are used, have further substantiated by investigators using MRI, CT or lymphangiographic imaging. This work tries to obtain three dimensional margins by observing enlarged nodes in CT scans in order to improve pelvic nodal chains clinical target volumes (CTVs) drawing, and by looking for corroborative evidence in the literature for a better delineation of tumour CTV. METHOD: Eleven consecutive patients (seven males, four females, mean age 62 years, range 43-78) with CT diagnosis of nodal involvement caused by pathologically proved carcinoma of the cervix (n = 2), carcinoma of the rectum (n = 2), carcinoma of the prostate (n = 2), non-Hodgkin lymphoma (n = 2), Hodgkin lymphoma (n = 1), carcinoma of the penis (n = 1) and carcinoma of the corpus uteri (n = 1) were retrospectively reviewed. Sixty CT scans with 67 enlarged pelvic nodes were reviewed in order to record the more proximal structures (muscle, bone, vessels, cutis or subcutis and other organs) to each enlarged node or group of nodes according to the four surfaces (anterior, lateral, posterior and medial) in a clockwise direction. RESULTS: A summary of the observations of each nodal chain and the number of occurrences of every marginal structure on axial CT slices is presented. Finally, simple guidelines are proposed. CONCLUSIONS: Tumour CTV should be based on individual tumour anatomy-mainly for lateral beams as it results from sagittal T2 weighted MRI images. Boundaries of pelvic nodes CTVs can be derived from observations of enlarged lymph nodes in CT scans.  相似文献

A patient with a CD4+ refractory peripheral T-cell lymphoma (PTL), subtype angioimmunoblastic T-cell lymphoma (AILD), was treated with a human monoclonal anti-CD4 antibody (HuMax-CD4) iv once weekly for 10 wk. Early during treatment all palpable enlarged lymph nodes disappeared. A decline of normal CD4+ T-cells in the blood mirrored the treatment effect. Shortly after stopping treatment the patient relapsed with new enlarged lymph nodes. This time no antitumor effect was seen when HuMax-CD4 treatment was reinstituted. No severe side effects were observed during the antibody treatment. This case report is the first describing that HuMax-CD4 has antilymphoma activity in PTL and is an interesting drug to study further in patients with CD4+ PTL.  相似文献

子宫颈癌在女性恶性生殖系统肿瘤中的发生率居于首位,其中腹主动脉旁淋巴结(para-aortic lymph node PALN)转移与宫颈癌的治疗、预后密切相关。宫颈癌的淋巴转移途经多为宫颈旁、宫旁转移到闭孔、髂内外,再转移到髂总、骶前,最终汇集于腹主动脉旁淋巴结及(或)转移至锁骨上或腹股沟深淋巴结的阶梯式转移,但也存在不经过盆腔淋巴结的跳跃式转移。肿瘤的临床分期、有无宫旁浸润、盆腔淋巴结转移情况以及治疗前SCC 值等被认为是影响腹主动脉旁淋巴结转移的重要因素。术前评价淋巴结是否转移大多通过影像学诊断,CT通过显示淋巴结在横断面上的最大直径以及淋巴结内部密度改变来评价淋巴结是否转移,是目前应用最广泛的诊断方法,但其敏感性及准确性均低于PET 。肿大的腹主动脉旁淋巴结可以手术切除,特别是腹膜外腹主动脉旁淋巴结切除术以及腹腔镜下腹主动脉旁淋巴结切除术,由于其创伤小、对术后放疗影响小等优点逐渐发展起来,既能诊断,同时也有重要的治疗价值。腹主动脉旁淋巴结是宫颈癌治疗后最常见的复发部位之一,但被认为更多是局部病变,对复发淋巴结区域采取积极治疗仍可明显改善生存率。但初治时即存在腹主动脉旁淋巴结转移者,患者往往同时有远处转移或会在较短时间内出现远处转移,预后差。   相似文献

Hodgkin lymphoma is a well-known clinico-pathological entity with a stable incidence among time accounting for 1200 new cases each year in France. The disease is one of the most curable cancer and occurs often in young patients with a median age at 33 years, the major clinical symptoms are lymph nodes mostly above the diaphragm (mediastinal and supra-clavicular). The diagnosis should be suggested with non-specific symptoms such as fever, night sweats, pruritus, weight-loss, lymph node, cough.. leading to prescribe routine exams like blood test with leucocyte count, erythrocyte sedimentation rate and chest Xray. Treatments always include chemotherapy and radiotherapy in localized disease and at a low dose only in involved fields. The usually good prognostic of Hodgkin lymphoma may not let us forget that there are still deaths in patients with refractory or early relapse of the disease. There is still an unmet need is these patients and the search for new drugs is essential.  相似文献
