The authors presents a retrospective analysis of mortality from laryngeal cancer in the population of Jelenia Góra in the years 1982-1989. The analysis was based on the death register books and cards.

The incidence of leukaemia was compared in various provinces of Lower Silesia in the years 1972-1985. The highest incidence was in the Province of Wroclaw and the Province of Jelenia Góra, in the Province of Legnica it was lower and the lowest was found in the Province of Walbrzych. A similar sequence of the incidence was found when the analysis was carried out in groups of sex and place of residence (villages and towns). The analysis according to disease entities showed that the incidence of acute myeloid leukaemia was in the Province of Jelenia Góra, where the disease was more common in females. The authors think that the concentration and development of industry may be the cause of differences in the incidence of these diseases in various provinces of Lower Silesia.

The incidence of lymphomas (Hodgkin's disease, non-Hodgkin lymphoma), chronic lymphatic leukaemia was compared in four provinces in Lower Silesia. The highest incidence was in the Province of Wroclaw, followed in decreasing order by Legnica, Walbrzych and Jelenia Góra. The mean annual crude index of the incidence of these diseases was in these provinces respectively: Hodgkin's disease: 2.51; 1.94; 2.46; 1.65. Non-Hodgkin lymphoma: 1.72; 1.63; 1.68; 1.66. Chronic lymphocytic leukaemia: 2.10; 1.86; 1.28 and 1.62. The highest increasing trend in this incidence was noted in the province of Legnica and the Province of Wroclaw, and in these provinces the prognosis for future increase was worst. In the Province of Legnica the highest increasing tendency of non-Hodgkin lymphoma was noted. The much higher incidence of these malignancies in Lower Silesia in relation to the whole country suggests that some factors there may increase the susceptibility to this disease. However, in relation to other countries, this incidence is within the range of moderate values.

On the basis of data obtained from hospitals and outpatient clinics in Lower Silesia the incidence of haematological malignancies was analysed in the years 1972-1985. Totally 3739 cases were notified, mainly in urban populations. The mean annual index of incidence of leukaemias and lymphoproliferative disorders was in men 4.57/100,000 population, and in women 3.79, while the incidence index of chronic lymphoreticular system malignancies was 6.91 in men and 4.5 in women. With the exception of acute myeloid leukemia an increasing trend of incidence was noted, which was slight for Hodgkin's disease, chronic myeloid leukaemia and polycythaemia vera, and highest for non-Hodgkin lymphoma. About 30% of haematological malignancy cases have not been notified, and perhaps this was due to inadequate terminology of these diseases in the international register.

Econometric analysis of phase duration for blood morphology and basophil count alterations in chronic granulocytic leukaemia.

The retrospective analysis of 40 cases with chronic granulocytic leukemia revealed an average survival time of 39 months. Modal proportions between the chronic, accelerated and acute blastic crisis amounted to 25:6:8 months. The characteristic points and curves for peripheral white cell, blast cell, basophil cell and thrombocyte counts as well as haemoglobin levels were determined separately in 20 patients with long and in 20 with short survival time. Comparisons indicate among others that Busulphan sensitivity is an essential factor for a longer survival time of CGL patients.
