A characteristic feature of many cancer types is their ability to metastasise to the skeleton. Bone is the most common site of metastatic invasion, after hematogenous spreading of breast cancer. Early detection of bone metastases is mandatory in the evaluation and management of these patients. Bone scintigraphy is commonly performed in detection and evaluation bone metastases. Tumor markers are present in healthy individuals as well as in patients with malignant diseases but in different concentration. Aim of study was to correlate serum levels of tumor marker Ca (15-3), CEA and presence of bone metastases detected by bone scintigraphy. Study included 25 patients with breast cancer, previously surgically treated. All patients underwent whole body scintigraphy. Ca (15-3) and CEA was measured by radioimmunoassay. Presence, number of bone metastases were correlated with Ca (15-3) and CEA levels. Median age of patients included in study was 50 varying from 30 to 67. Bone scintigraphy revealed bone metastases in 16 (64%) patients. A weak correlation was found between number of metastases and level of Ca (15-3) (r=0.139, p=0.254). Significant differences in Ca (15-3) level was found in patient with metastases compared to patients without metastases (chi square 0, p=1.0). Good correlation was found between number of metastases and serum level of CEA. Correlation between level of two tumor markers Ca (15-3) and CEA was a weak (r = 0.096 , p=0.323). Bone scintigraphy is a sensitive diagnostic toll for detecting breast cancer metastases to bone. Serum levels of tumor markes in isolation can not give complete accuracy about bone metastases.

BACKGROUND AND AIM Bone metastases are of the most frequent in prostate cancer. Serum prostate specific antigen--PSA has been suggested as an accurate means of monitoring prostate cancer. Whole body scintigraphy are currently the most widely used diagnostic procedures for metastases to the bone, the most common site of distant tumor spread. Aim of the study was to determinate relation between PSA level, number of metastases and 99mTc- MDP (methyl-diphosponate) uptake in patients with previous prostatectomy for prostate cancer. PATIENTS AND METHODS Study enrolled 15 patients after previous prostatectomy for prostate cancer (histologically proven). Standard whole body scintigraphy (WBS) was performed 3 hours after intravenous application of 740 MBq 99mTc-MDP. Total PSA was measured by MEIA-Microparticle Enzyme Immunoassay. RESULTS Group 1: 12/15 (80%) patients were with WBS detected metastases. Correlation of PSA level and number of detected bone metastases was good (r=0.79). Correlation of PSA level and uptake intensity of 99mTc-MDP (score 3) was positive and significant (r=0.706). CONCLUSION PSA values were highly predictive for WBS results. PSA values correlated well with number of metastases. We propose no WBS in patients with normal PSA level. WBS is a sensitive diagnostic tool for detecting prostate cancer metastases to bone. PSA levels is good and simpler marker for disease progression, but that neither technique in isolation gives complete accuracy.

Breast cancer is one of the most frequent types of cancer affecting women. After hematogenous spreading of cancer, axial skeleton is most frequently involved. Bone scintigraphy is commonly performed in detection and evaluation of bone metastases. In breast cancer, marker Ca 15-3 is widely accepted in follow-up and detection of disease recurrence. Aim of the study was to correlate levels of tumor marker Ca 15-3 and presence of bone metastases detected by bone scintigraphy. Study included 25 patients with breast cancer, previously surgically treated. All patients underwent total body scintigraphy. Ca 15-3 was measured by radioimmunoassay. Presence, number and location of bone metastases were correlated with Ca 15-3 levels. Bone scintigraphy revealed bone metastases in 16 (64%) patients. 11 (44%) patients with metastases and 1 patient (4%) without scintigraphically visible metastases had elevated Ca 15-3 levels. Significant difference in distribution of metastases was found for spine (t=3.930, p=0.008). Correlation between intensity of radiopharmaceutical uptake and level of Ca 15-3 in patients was positive (r =0.405). A weak correlation was found between number of metastases and level of Ca 15-3 (r=0.139). Significant differences in Ca 15-3 level was found in patients with metastases compared to patients without metastases (chi square 0, p =1.0). Since no significant correlation was found between level of Ca 15-3 and number of metastases, we consider scintigraphy an appropriate method for assessment of bone metastases in breast cancer.

Background. Due to specific war and post-war situation in Balkan region, differences in the number, type, development, biological course, treatment of malignant tumours and its outcome are possible. In order to perceive the situation realistically, it is necessary to gather continuously exact data about malignant tumours and compare them with the data from other European and world countries.The aim of the study was to collect and analyse the data on cancer incidence in the region of Sarajevo city, which represents a symbol of difficult times in the recent past, and to compare it to the incidence in the neighbouring countries. Patients and methods. Data on all newly diagnosed cancer cases, permanent residents of Sarajevo Canton, in the years 1999 and 2000 were collected. Crude incidence rate has been calculated according to the years observed, gender and localizations of the disease The data were compared to the cancer registries of Slovenia and Croatia and were observed in the light of specific local situation. Results. The crude cancer incidence of all sites but skin was the highest in both years and by both genders in Croatia. The incidence of the most common tumours (lung and breast cancer) was similar in all three countries. The differences in the incidence between both genders in the Sarajevo canton were registered in laryngeal and urinary bladder cancer, as well as in bone and cartilage sarcoma. Cervical cancer had extremely high incidence and was high up on the incidence list in the Sarajevo canton, which correlates with the data in developing countries. The incidence of other tumours in the post-war period is reaching expected numbers. Conclusions. It is difficult to identify whether the war and post-war stress, irregular and insufficient nutrition during and after the siege of the city of Sarajevo or some other factor influenced the cancer incidence among exposed population. The prevalence of smoking in the whole region is extremely high, in Bosnia and Herzegovina almost complete, which can influence not only the incidence of lung cancer but also laryngeal and urinary bladder cancer.

UNLABELLED Due to the specific war and post-war situation in Bosnia and Herzegovina it is possible to notice some differences in the number, type, advancement, biological course, treatment and its outcome. The actual situation which appeared in connection to depleted uranium has additionally raised questions about its influence on human health and about eventual increase in the number of malignant diseases in Bosnia and Herzegovina. In public, we often see that there are claims about enormous increase in the incidence of cancer. In order to achieve a realistic picture of actual condition and to avoid panic and ignorant attitude, correct and constant data of malignant tumors are necessary. THE AIM OF THE STUDY To collect and analyze data on population with malignant tumors in the region of Sarajevo city, which represents a symbol of difficult times in our country in the recent past. MATERIAL AND METHODS We have collected and analysed data on, population with malignant tumors which included persons with permanent residence in Sarajevo Canton during 5-year period, from 01.01.1998, until 31.12.2002. Results were compared to regional and world indicators, and were observed in the light of specific local situation. RESULTS During period of 5 years (1998-2002) 7733 new cases of malignant tumors were registered in Sarajevo Canton; 3940 among men and 3809 among women. Mostly registered tumors were: lung cancer, amelanotic skin tumors, breast cancer, colorectal cancer, cervical and uterine cancer, urinary bladder cancer, prostate cancer and cancer of larynx. CONCLUSIONS Number of all malignant tumors in the region of Sarajevo Canton correlates to those in South European countries and the one estimated by GLOBCAN 2000. High number was registered in 1998, possibly due to normalization of the health services (diagnostics and treatment of malignant tumors), which didn't exist during the war and early post-war period. After 2000, there is a gradual increase in the number of people with malignant tumors. The most common tumors are lung and breast cancer. Significant differences to estimation and data registrated in other South European counties is high number of laryngeal cancer, urinary bladder cancer, bone and cartilage sarcoma, brain tumors and malignant lymphomas among both genders. Cervical cancer is extremely high up on the list, which correlates with data in developing countries. The incidence of smoking in Bosnia and Herzegovina is extremely high, almost complete, which can influence not only the appearance of lung cancer but also laryngeal and urinary bladder cancer. It is hard to say whether the war and post-war stress, irregular and insufficient nutrition during and after the siege of the city or some other factor have influenced their appearance among exposed population and differences in the observed incidence.

The surgery Department of the Regional Hospital was opened on 1st July, 1894 in Sarajevo, what meant the beginnings of European surgery school influence here. The School was in the second half of its activity, better known as "century of surgery". The building, fittings, equipment and staff continued their work here coping the Viennese school achievements. It was headed by the prominent European surgeon, primarius Dr Josef Preindisberger, first assistant to the great personality Dr. Billroth. In the way this institution became a referral centre for two other hospitals in Sarajevo: the Vakuf's and the Military Hospital, but for some 17 more in BH, which were built in the course of ten years. Because of the therapeutic success in the domain of the general surgery and diseases of the eye and according the annual reports, the first 50 beds became insufficient for all those who wanted the treatment. So, the Department was enlarged, in 1905 a new regional Hospital was planned, to act as clinics. The World War 1 stopped the plans. During the period of Kingdom of Yugoslavia, destroyed by war, the Surgery Department continued its work with the doctors educated to continue the work on the pre war level. As a broad pathology basis, but the need of space that time chief surgeon. Primarius Milivoje Kostić worked out in details the former plan of the new hospital building up with a base for clinics. It was accepted as a ten years project, which, to the regrets, did not come to existence to the World War 2.(ABSTRACT TRUNCATED AT 250 WORDS)
