Staging in untreated patients with small cell lung cancer.
In order to describe the real biological behavior of the small-cell lung cancer we have analyzed survival rates of 66 patients with small-cell lung cancer who did not receive any specific anti cancer therapy. Also, objective of this study was to evaluate the staging system of the small-cell lung cancer. Untreated small-cell lung cancer patients with limited stage disease had statistically significant (p < 0.05) better survival rates in comparison to patients with extensive stage disease. T and N factor of the TNM classification did not influence the survival in untreated small-cell lung cancer patients. It appears that the TNM staging system is not predicting survival probabilities of untreated patients with small-cell lung cancer, while the two-stage system appeared very well based on survival probabilities of these patients.

Prognostic parameters in low-grade non-Hodgkin's lymphomas.
In a group of 73 patients with low-grade non-Hodgkin's lymphomas (LG NHL) a multivariate analysis of the following variables was performed: pathological types following the International Working Formulation, clinical stage, B-symptoms, erythrocyte sedimentation rate, hemoglobin level, white blood cell and lymphocyte count, serum gamma globulin level, serum total lactic dehydrogenase (LDH) level, mitotic and complete remission. The patients with lymphocytic lymphoma manifested the best survival in this group. Low-proliferative lymphomas showed better survival than high-proliferative lymphomas at 3 and 10 years. B-symptoms, serum total LDH level and complete remission were significant independent prognostic factors.

Survival analysis of untreated patients with non-small-cell lung cancer.
The survival rate analysis of 130 patients with non-small-cell lung cancer who did not receive any specific anticancer therapy showed no statistically significant differences in the survival rates between various TNM combinations classified into stage groups II, IIIa, IIIb, and IV, as proposed by Mountain in 1989 and adopted by the American Joint Committee on Cancer. Following these findings, based on survival probabilities, two distinctive staging groups could be distinguished. The first stage group was composed of only the T1, 2N0, M0 combination, and the second of all other TNM combinations. In a purely biologic sense of tumor growth, the lymph node involvement appeared to be the crucial factor determining the length of survival.

Hypersensitivity to Parietaria officinalis pollen in newcomers to the area with the plant.
Hypersensitivity to Parietaria officinalis (wall pellitory) pollen and other environmental allergens was studied in pollinosis patients allergic to P. officinalis pollen who were born in areas without P. officinalis and later moved to the city of Split, where P. officinalis is responsible for some 65% of pollinosis cases. Highly significant positive correlations were found for both the intensity of skin test reaction and concentration of specific serum IgE with the length of residence in the area. In contrast, the respective data on subjects hypersensitive to P. officinalis pollen allergen, but born and living in the area of Split, revealed a tendency to negative correlation between age and intensity of hypersensitivity to P. officinalis. A number of patients from both groups were tested for presence of serum IgE antibodies specific for 14 common environmental allergens. Hypersensitivity to P. officinalis pollen was associated with hypersensitivity to olive, mugwort, and birch pollen in newcomers; hypersensitivity to birch and, to some extent, olive pollen was significantly more frequent in newcomers than in autochthonous patients who were allergic to P. officinalis pollen. Regardless of whether the patients were autochthons or newcomers to the area with P. officinalis, hypersensitivity to P. officinalis mostly excluded hypersensitivity to Dermatophagoides farinae and D. pteronyssinus, and vice versa.

Role of digoxin in right ventricular failure due to chronic cor pulmonale.
The effect of digoxin in the treatment of decompensated chronic cor pulmonale was investigated in a randomized double-blind, cross-over, placebo-controlled trial. A total of 34 successive patients with evident right heart failure were included in the study. The mean maintenance daily dose of digoxin was 0.30 +/- 0.03 mg with the mean serum level of 1.7 +/- 0.7 nmol/L. The severity of heart failure was assessed according to a clinicoradiographic scoring system (Heart Failure Score). The heart failure worsened during the placebo-period in eight (23.5%) patients (four with atrial fibrillation, two with a third heart sound (S3), one with a cardiothoracic ratio of more than 0.5 and one with sinus rhythm). By regression analysis, the heart failure significantly worsened only in the subgroup of patients with atrial fibrillation. Digoxin was successfully (without worsening of the heart failure) discontinued in 26 (76.5%) patients. No significant improvement was observed in the patients with S3 gallop. It was concluded that digoxin had no beneficial effect in chronic cor pulmonale patients with heart failure, except in those with atrial fibrillation.

[The prognostic model--an aid for decision-making in the use of adjuvant cytostatic therapy in breast cancer].
The prognostic model as a help in deciding for the application of the adjuvant cytostatic therapy (ACT) in breast cancer is proposed. Risk factors including size of tumour, status of axial, value of hormonal receptors, grade of differentiation of tumour and age are included in the prognostic model. The clinical study comprises patients with breast cancer in premenopausal age with (30 patients) and without ACT (36). By using a multiple regression method and correlation analysis (multivariate analysis), the "weight"--the values of each risk factor have been determined in relation to the disease free interval and survival are obtained by employing the proposed prognostic model. By simple mathematical methods type of therapy is determined by the prognosis. This is the proposed model: Y = beta 0 + beta 1 x x1 + beta 2 x x2 + ... + beta k x xk. Coefficient values for each risk factor have been obtained by this clinical study. Full attention is not paid to the results of the ACT application in this presentation.
