  • Nonspecific suppressions of the immune responses have been reported to occur in the cancer-bearing patients. The mechanisms responsible for these immunosuppressions remain unclear but some investigators suggested that the immunosuppressions may result from immunosuppressive factors exudated from tumor masses. This study was undertaken to evaluate the in vivo effects of ascitic and pleural fluids from patients with cancers metastatic to peritoneum or pleura on the immune responses of mice. Non-cancerous ascitic and pleural effusions were used as controls. The ascitic fluids from hepatomap atients and pleural fluids from pulmonary carcinoma patients decreased both the delayed-type hypersensitivity and the antibody formation only when these were injected before antigenic stimulation. Control effusions exerted no effect on the immune responses to mice. These results suggested that cancerous fluids suppressed the immune responses by affecting the afferent arc of the immune system.

  • Background: Recently there has been a trend of an increasing incidence of mediastinal tuberculous lymphadenitis(MTL) in adults. MTL often cause bronchial stenosis or esophago-mediastinal fistula. In spite of effective treatment, it is difficult to cure. Moreover, relapse frequently occurs. Authors analyzed chest CT findings and clinical features of 29 cases with MTL Methods: 29 cases with MTL were retrospectively studied with the clinical and radiologic features from April 1990 to March 1995 Results: 1) A total of 29 cases were studied. 12 cases were male and 17 cases were female. The male to female ratio was 1:1.4 Mean age was 29 years old. The 3rd decade(45%) was the most prevalent age group 2) The most common presenting symptoms and signs were palpable neck masses(62%) followed by cough(59%) and sputum(38%) 3) Except in one case of MTL, all patients had coexisting pulmonary tuberculosis, cervical tuberculous lymphadenitis, endobronchial tuberculosis and tuberculous pleurisy. Among the coexisting tuberculous diseases, Pulmonary tuberculosis was the most common(76%) 4) On simple chest X-ray, mediastinal enlargement was noted in 21 cases(72%), but it was not noted in 8 cases(28%). The most frequently involving site was the paratracheal node in 16 cases(72%). Rt side predominence(73%) was noted 5) Patterns of node appearance on a postcontrast CT scan were classified into 3 types. There were 19 cases(30%) of the Homogenous type, 30 cases(47%) of the Central low density type and 15 cases(23%) of the Peripheral fat obliteration type. The most common type was the central low density type. The most common lymph node size was 1~2 cm(88%) 6) The most frequently involved site was the paratracheal node in 26 cases(89%) by chest CT. Rt side(63%) was predominant 7) 9 cases(43%) had complete therapy and most common treatment duration was 13 - 18 months. 12 cases(57%) had incomplete continuing antituberculous medication and half of the cases had been treated above 19 months. Conclusion: Chest CT findings of MTL showed central low density area and peripheral rim enhancement, so this characteristic findings could differentiate it from other mediastinal diseases and help a diagnosis of tuberculosis. In spite of effective antituberculous medication, it is difficult to cure. Moreover, relapse frequently occurs. Further studies will be needed of the clinical features and the treatment of MTL.

  • Background: In principle, cervical tuberculous lymphadenitis (CTBL) is a medical disease that may require surgical treatment, particularly in young women who complain of psychosocial and cosmetic problems. We encountered 13 cases of aggravated CTBL treated surgically despite the appropriate course of antituberculous chemotherapy. We report the clinical characteristis of these cases. Methods: The clinical data of 13 patients with aggravated CTBL requiring surgical treatment from January 2000 to December 2006 at the Department of Chest Medicine, Internal Medicine and Plastic Surgery, National Medical Center was reviewed retrospectively. Results: Twelve of the 13 cases (92%) were female. The most common age was 21~30 years (69%). Multiple nodes were palpated in 11 cases (85%). The supraclavicular lymph nodes were sites the most commonly involved (54%). The other involved sites in the order of decreasing frequency were the jugular chain, posterior cervical, submandibular and infraauricular lymph nodes. A palpable mass was the most commonsymptom. Neck pain was reported in 3 cases (23%). General symptoms such as weight loss, fatigue, anorexia and night sweats were noted in 5 cases (38%). Respiratory symptoms such as cough, sputum, hemoptysis, dyspnea and chest pain were observed in 4 cases (31%). Pulmonary tuberculosis was noted in 11 cases (85%). Other extrapulmonary tuberculosis coexisted in 4 cases (31%). This suggests that surgical CTBLs may be manifestations of a systemic disease and might be difficult to treat. Most cases (92%) were stages 2 and 3 at the initial diagnostic period but all cases fell into stage 4 and 5 when reassesed before surgery. The average duration of anti-TB chemotherapy before and after surgery was 10.2 and 15.2 months, respectively. The 13 patients were followed up until June. 2008. Among them, 2 cases had newly developed CTBL and the other 11cases showed no recurrence. Conclusion: In principle, CTBL is the medical disease. However, despite the appropriate course of anti-TB chemotherapy, CTBL can progress to a more advanced stages and grow rapidly to a large-sized or fistulous mass with a persistent abscess. Surgical treatment may be inevitable for patients with psychosocial and cosmetic problems caused by these masses, particularly in young women.
