[Chemotherapy of metastasizing colonic carcinomas with nitrosourea compounts. Retrospective analysis].

35 patients with advanced, and previously untreated, colorectal cancer underwent therapy with a combination of 5-fluorouracil, vincristine, DTIC, or one of the nitrosoureas, BCNU or methyl-CCNU, respectively. No complete remission was achieved. 33% of all cases resulted in partial remission and lasted for approximately 3--4 months. Complications were perilous such as neutro- and thrombocytopenia. The overal quality of life was poor. Though several parameters influence these results, we think that the above-listed nitrosoureas do not add substance to the chemotherapy of colorectal cancer.

Ferritin in bone marrow and serum in iron deficiency and iron overload.

Nonheme iron and ferritin in the bone marrow and serum ferritin was investigated in patients with iron deficiency anaemia or iron overload. As controls served patients without any disturbance of the iron metabolism. There is a precise correlation between the nonheme iron and ferritin in the bone marrow of patients with and without disturbance of iron metabolism. A correlation was also found between the ferritin in the bone marrow and the serum. Nonheme iron and ferritin in the bone marrow and serum ferritin was decreased in patients with iron deficiency anaemia. Conversely, the same parameters were increased in patients with iron overload.

[Serum ferritin in iron deficiency anaemia (author's transl)].

Red cell indices, plasma iron, total iron-binding capacity and serum ferritin levels were measured in 73 patients with iron deficiency anaemia. There was decreased plasma iron and MCHC with an increased total iron-binding capacity in 38 patients (type I iron deficiency anaemia). There was no hypochromia in 18 patients with decreased plasma iron and normal total iron-binding capacity; haemoglobin concentration was higher than 90 g/l (type II). Normal MCHC, plasma iron and total iron-binding capacity were found in 17 patients with haemoglobin values higher than 105 g/l (type III). Serum ferritin measurements were made by the immunoradiometric assay. The ferritin concentration was less than 40 micron/l in 66 patients with iron deficiency anaemia. The test proved reliable in diagnosing mild iron deficiency anaemia (types II and III) without bone marrow aspiration.

[Significance of metabolic parameters in Hodgkin's disease (author's transl)].

In 56 patients with Hodgkin's disease, the following bloodtests were carried out: erythrocyte sedimentation rate (ESR), fibrinogen, alpha2-globuline, serium iron concentrations and alkaline phosphatase activity. In some patients we additionally measured alkaline leucocyte phosphatase and serum ribonuclease activity. In our series ESR, serum iron and alpha2-globuline concentrations were the most sensitive metabolic parameters. A rise in fibrinogen concentration, alkaline phosphatase and serum ribonclease activity seems to indicate extensive disease. It is not possible, however, to discern between a state of remission and stage I by means of these parameters. ESR, serum iron and alpha2-globuline concentrations might be either elevated or normal in both instances. These parameters seem important in order to distinguish between a remission or stage I on the one hand and extensive disease in stage III and IV on the other hand. Concomitant findings of ESR above 40 mmh, elevated concentrations of fibrinogen and alpha2-globuline, as well as elevated alkaline phosphatase and serum and serum ribonuclease activity mostly indicate stage III or IV.

[Aplastic anemia-a preleukemic stage (author's transl)].

In a group of 44 patients with primary and secondary aplastic anemia, four (9%) developed an acute leukemia. Cytological changes that pointed to a preleukemia were not observed during the preleukemic stage. The possibility is discussed whether a aplastic anemia and a preleukemia can be distinguished by cytological, cytochemical and cytogenetic tests, by agar-culture technique, liquid-culture and determination of reverse transcriptase.
