Influence of stress related to war on biological and morphological characteristics of breast cancer in a defined population.

PURPOSE: To assess differences between patients with breast cancer before, during and after the 1991-1995 war in Croatia. MATERIAL AND METHODS: We analyzed 660 patients of Pozesko-Slavonska County, during the three periods. Relative predictive values of patient's characteristics and stage of tumor were assessed using the X2-test, and survival with Kaplan-Meier analysis. RESULTS: Tumors were significantly more often of higher stages (IIA and IIB) and with axillary lymph node metastases (N1) during the war, than in pre-war and post-war period.Breast cancer was significantly more frequent in patients who previously experienced death in the family (35,3%). The Kaplan-Meier analysis showed correlation between survival, T and N stages of tumor and clinical stage of tumor. CONCLUSION: The war aggression towards Croatia with its impact on our patients, contributed to modification of characteristics of breast cancer in the analyzed period.

Diagnosis and therapy of gestational breast cancer: a review.

PURPOSE: In spite of the general consensus on the issue, to point to major dilemmas which appear in this matter of multidisciplinary interest, and to review current concepts on how to achieve optimal diagnostic and therapeutic outcome. RESULTS: Recent literature data show that the rate of gestational breast cancer, according to most protocols, range from 0.2% to 3.8%. By definition, the clinical manifestation of this type of carcinoma is expected to occur during pregnancy or within one year after delivery. The mode of treatment and prognosis is identical to those of women with breast carcinoma beyond pregnancy, except for radiotherapy that is not indicated during pregnancy and selective use of cytostatics in polychemotherapy during the first trimester. The only exceptions to this practice are women with any advanced stage of the disease due to delayed diagnosis. Results of large studies indicate that the therapy for breast cancer has no adversarial effect on the prognosis of subsequent pregnancy. CONCLUSION: The evaluation and management of women with gestational breast cancer requires a multidisciplinary approach. A chemotherapeutic regimen should be individualised to a maximum reduction of risk, if applied in the second and third trimester. Surgical therapy may include mastectomy and sparing operative procedures. Sentinel node biopsy should be considered in node negative patients. Radiotherapy should be postponed to the postpartum period.
