[Correlation between endoscopy and histology of 48 cases of superficial stomach cancer].

The relationship between different endoscopic (gross appearance, diameter, localization, morphological type according to the Japanese Endoscopic Society) and histological parameters (type of cancer according to Lauren, tumor infiltration, association with metaplastic chronic gastritis) were analyzed retrospectively in 48 patients operated on for early gastric cancer. Endoscopy and histology provided a preoperative diagnosis of malignancy in 89.6% of the cases. With endoscopy alone the results were 23% malignancy, 44% suspicious and 33 benign. The antrum was the preferential site and type III the most frequent form. 62% of early gastric cancers were of the intestinal type and the average age of the patients was higher than for the diffuse type. Metaplastic chronic gastritis was associated in 67% of the intestinal type and in 21.5% of the infiltrating type. The degree of tumor infiltration was related to the diameter of the lesion, irrespective of the histological type. Since a malignant or suspicious lesion was diagnosed in only 67% by endoscopy alone, it is imperative to perform several biopsies of all gastric lesions, including even the smallest: 11 cancers of type III and IIc in this series had a diameter inferior to 1 cm and had been classified endoscopically as benign.

[Prevalence of hysterectomy and cancer of the uterus in the population of Tessin canton].

The study presents an analysis of the prevalence of hysterectomy during the year 1982 in Canton Ticino, where the rate (507) per 100'000 women is double that found in the West Midlands area of Great Britain (P less than 0,001). No statisticaly significant difference is found in the mortality rate or morbidity rate for tumour of the cervix and body of the uterus.

Proliferative patterns of lymphocytes in lymph nodes during tumour development: involvement of T and B cell areas.

DNA-synthetizing lymphocytes were identified in the lymph nodes regional and more distal to the site of developing P-815 tumours by incorporation of [3H]-thymidine followed by autoradiography of lymph node sections. It appeared that not only T but also B cell areas of draining and to a lesser extent of distal lymph nodes were stimulated by the growing tumour. This result was unexpected since neither humoral nor tumour cell-bound antibody could be identified so far as a functional correlate of B cell stimulation. In general the proliferative response of lymphocytes followed a biphasic pattern with an early peak of reactivity on days 2-3 and a second peak around day 12-15 after tumour cell inoculation. In the draining (axillary) lymph node the second peak of reactivity was suppressed, possibly as a consequence of metastatic tumour cells in this node when tumour cells were inoculated in the flank. The pattern of lymphocyte stimulation revealed larger individual variations after tumour cell inoculation in the flank than the foot pad. These results were associated with a slower and less regular drainage of carbon particles from the flank to the axillary and exceptionally the brachial lymph node than from the foot pad to the popliteal node after injection of India ink.

[A case of metastasizing paraganglioma of the larynx].

The case of a 68-year-old woman who died of a metastasizing paraganglioma of the larynx is reported. The diagnostic problems related with this disease and its relationship with the tumors of the APUD system are particularly discussed.

[Cytomegalovirus pneumonia in primarily healthy adults].

The case is reported of an 18-year-old woman hospitalized with severe dyspnea and high temperature. Chest X-ray showed pneumonia with interstitial and air-space consolidation patterns. Serologic tests revealed a cytomegalovirus infection (CMV). The blood findings showed anemia of infectious origin. Liver biopsy was consistent with CMV-hepatitis. CMV-pneumonia in an otherwise healthy patient is extremely rare; a review of the literature revealed only four other cases.

[Unusual autoimmune and neoplastic associated diseases in Sjogren's syndrome].

In an unselected series of 12 patients with Sjögren's syndrome the following autoimmune diseases were observed: severe myxedema due to Hashimotos thyroiditis in four, subclinical thyroid hypofunction in one, diffuse hyperthyroidism in one, glomerulonephritis in two, chronic active hepatitis in one, lupus erythematodes disseminatus in three (one with idiopathic thrombocytopenic purpura), classical rheumatoid arthritis in two. A rare familial occurrence was seen in two sisters. The only male in this group exhibited coexistence of a benign adenolymphoma of the parotid gland (Warthin's tumor) with a malignant non-Hodgkin lymphoma.

[Prolymphocytic leukaemia: a new clinical entity (author's transl)].

A 67-year-old woman, at first diagnosed to have acute lymphocytic leukaemia, developed all the characteristic signs of so-called prolymphocytic leukaemia, namely severe general symptoms of illness, marked hepatosplenomegaly in the absence of lymphadenopathy, extreme leukocytosis (at times more than 1000 x 10(9)/l). Prolymphocytic leukaemia is now considered to be an especially unfavourable form of chronic lymphocytic leukaemia.

Malignant non-Hodgkin's lymphoma (NHL) in childhood. Retrospective analysis of 34 cases.

Of 47 children with an initial diagnosis of lymphosarcoma, reticulosarcoma or Non-Hodgkin's lymphoma (NHL), 13 had to be excluded at the histologic reevaluation: in 10 an undifferentiated sarcoma, in 2 Hodgkin lymphoma was found; in one patient no definite classification of the tumor was possible. Of the remaining 34 patients there were 26 boys and 8 girls. One patient had a nodular, 33 a diffuse NHL. Of the latter 16 had a Burkitt-type (LB-), 3 a lymphoblastic, convoluted (LC-), 8 a lymphoblastic, "other" (LO-) and 6 a histiocytoid (H-) NHL. Primary localization: abdomen: 13/34; "peripheral" lymph nodes: 9/34; mediastinum: 5/34; nasopharynx: 4/34; subcutis: 2/34; skeleton: 1/34. Twelve of 17 NHL with primary localization in the abdomen or nasopharynx were LB-NHL, 8/14 NHL with primary localization in "peripheral" nodes or mediastinum were LC- or LO-NHL. Only 2/17 NHL with abdominal or nasopharyngeal primary, but 9/14 NHL with "peripheral" nodal or mediastinal primary developed leukemic extension and/or CNS involvement. 6 of 34 patients are living without evidence of disease for 1 1/2+ to 13+ years; 5/34 died but lived for 85, 57, 37, 22 and 22 months; 9/34 lived 6--12 months; 14/34 died within less than 6 months. Patients with abdominal primary either died within 5 months or survived (for 165+, 63+ and 25+ months). Aggressive local therapy (surgery and radiotherapy with approximately 4000 R) may be adequate for strictly localized (stage I) disease, particularly if the primary localization is abdominal. In all other diffuse NHL of childhood an early, aggressive chemotherapy, later combined with radiotherapy to bulk disease and prophylactic CNS-treatment is essential for inducing long-term remissions and, possibly, cures. For prognosis the primary localization appeared to be more important than histology and stage. The most decisive factor, however, is therapy.

Problems relating to immunoselection of leukemias.

Problems relating to immunoselection of neoplastic, in particular leukemic, cell lines are reviewed. Since there is ample evidence that specific immune reactions of the host against malignant neoplastic cells do occur, it becomes important to consider the effectiveness and the relevance of immunity in suppression or elimination of neoplastic growth. Emphasis is placed on experimental results obtained in syngeneic tumor-host combinations, because they more closely resemble the situation of spontaneous tumorigenesis or leukemogenesis than xenogeneic or allogeneic model systems. Studies of types of neoplasia observed in cases of human immunodeficiency syndromes offer an important insight into problems involved in immunoselection of leukemic cell lines: the marked predominance of leukemias and lymphoreticular neoplasias in immunodeficient patients invites speculation on both the mechanisms of leukemogenesis and the relative importance of the immune system in eliminating malignant neoplastic cells.
