Criteria and procedures for breast conserving surgery.

AIM: Emphasizing circumstances that determine increasingly popular surgical approach of breast conserving surgery (BCS), used in lower grade breast tumors, while maintaining survival that is found when more radical procedures are used. PATIENTS AND METHODS: Several leading oncological protocols in the world are compared, using PubMed database, and our own experience. Data gathered are compared to conclusions of Consensus Conference on Breast Conservation (Milan, 2005). Furthermore, surgical contraindications found in our everyday work are considered, having in mind satisfactory cosmetic outcome, as well as keeping the 1 cm border of "clear" edges. Such more practical problems of edge detection can compromise BCS results. RESULTS: After observing several relevant protocols, we found very high frequency of mastectomy vs. BCS, despite the fact that stage of disease was low. We also found only 20% of absolute contraindications for BCS. Most frequent contraindication for BCS was multicentricity of the tumor (with micro calcifications), especially in ductal in situ carcinoma. CONCLUSION: BCS followed by radiation therapy with tumor-free edges is standard procedure in treatment of T1 and small T2 breast cancers. This approach implies higher risk of local recurrence (LR), although local recurrence is low (1% per year), with rates of survival similar to radical procedures.

Calcium at the carotid siphon as an indicator of internal carotid artery stenosis.

OBJECTIVES: Carotid siphon calcification is often visible on unenhanced head CT (UCT), but the relation to proximal carotid artery stenosis (CAS) is unclear. We investigated the association of carotid siphon calcification with the presence of CAS. METHODS: This IRB-waived retrospective study included 160 consecutive patients suspected of stroke (age 64 ± 14 years, 63 female) who underwent head UCT and CTA of the head and neck. CAS was rated on CTA as not present or present with non-significant (<50 %), moderate (50-69 %) or significant (≥70 %) stenosis. Presence, shape (on UCT) and volume (on CTA) of carotid siphon calcifications were related to CAS. RESULTS: Carotid siphon calcification was absent in 41 % of patients and bilateral in 94 % of those with calcifications. Presence, shape and volume of calcification resulted in odds ratios for having significant CAS of 10.1, 3.9 and 8.4, with 95 % CIs of 1.3-79.6, 1.1-14.1 and 2.6-26.8, respectively. Corresponding NPVs were 0.98, 0.98 and 0.96, while PPVs were 0.14, 0.07 and 0.29, respectively. CONCLUSION: Absence of calcification in the carotid artery siphon on UCT has high negative predictive value for carotid artery stenosis in patients with suspected stroke. However, siphon calcification is not a reliable indicator of significant carotid artery stenosis. KEY POINTS: • Many stroke patients do not have calcification in the carotid artery siphon. • Carotid stenosis ≥50 % is unlikely in stroke patients without siphon calcification. • Carotid siphon calcium is a poor indicator of significant carotid artery stenosis.

[Clinical recommendations for diagnosis, treatment and monitoring of patients with invasive breast cancer]. / Klinicke upute za dijagnozu, lijecenje i pracenje bolesnika oboljelih od invazivnog raka dojke.

Breast cancer is the most common malignancy in women. Preventive measures, early diagnosis and development of all treatment modalities (surgery, radiotherapy, chemotherapy, hormonal and targeted biologic therapy) led to improvement in survival and quality of life of the patient. In order to standardize and optimize the approach, following good clinical practice standards, we bring consensus guidelines for diagnosis, treatment and monitoring of breast cancer patients as a result of consensus of a multidisciplinary team of experts for breast cancer.

Extracorporeal fertilization in the world and in Croatia.

AIM: To point out the dangers, side effects and risks of medical assisted fertilization, in vitro fertilization, embryo transfer and injection on sperm in ovum for mother and the child. RESULTS: On the one hand the negative side effects for women of an abrupt rising risk for the development of neoplasm under pharmaceutical therapy are mentioned. Especially under a therapy which has the purpose to stimulate the ovulation of the ovary it lies around 100%. An increased level of certain hormones, as for example HCG, which influences the ovulation, is closely related with the risk of developing ovarian cancer. Clinical studies at more than 12000 infertile women (primary and secondary acyesis), with an average age of 30 years, show an elevated risk for the development of a malignant tumor of 98%. Also the application of Gonadotrophin is connected with a risk of 146% for the occurrence of cancer after a period of 15 years. FDT involves a risk of about 12% for the occurrence of breast cancer and shows also an aggravation for the risk of cancer of the endometrium from 79% up to 1152%. On the other hand the risk of spontaneous miscarriages under MAF, which is near 20%, and serious illness of the children, including 47% with need of intensive care unit support after birth, need to be realized. Furthermore the investigation of naturally obtained twins and through ART obtained twins shows in the arrangement a slower and poorer development of the children in the ART group with also great differences in physical development. In total the number of inherent malformation of newborns under the use of ART rises from 47 to 177%. With an installment of 9% we notice that children who came into being by IVF and ICS also fall more frequently ill. (Teething troubles, more hospitalizations and operations, higher frequency of major inherent malformations). CONCLUSION: All women who want to undergo a medical assisted fertilization should be informed about the side effects and risks for mother and child.

Fournier gangrene: our approach and patients.

AIM: This retrospective analysis presents our experience in treating Fournier gangrene (FG) and aims to bring in focus diagnostic and therapeutic problems as well as early and aggressive treatment. PATIENTS AND METHODS: A total of 16 male patients were included in the study. The gastrointestinal form was seen in 5 and the urogenital form in 11 patients. The subjects ranged in age from 39 to 74 years (average 61) for the urogenital, and from 48 to 72 (average 58) for the gastrointestinal form. Other conditions were seen in 9 patients (diabetes mellitus was most common). Most patients were infected with several bacteria. We performed colostomy in 1 patient, orchidectomy in 2 patients, cystostomy in 2 patients and penis amputation in 1 patient. Ultrasound-guided biopsy or aspiration, and CT was also used. Aggressive surgical necrectomy and aggressive antimicrobial therapy was used. RESULTS: Treatment was successful in 14 of 16 patients (87.5%). The length of hospitalization was 19-58 days (average 48) for the urogenital form and 24-56 days (average 41) for the gastrointestinal form. Mortality was 12.5%. A lethal outcome was recorded in two patients infected with methicillin-resistant Staphylococcus aureus. The average time between onset and hospitalization was 3-11 days (5 on average) for urogenital FG and 4-10 days (average 6) for gastrointestinal FG. Treatment was significantly longer in patients with a comorbidity, such as diabetes or liver cirrhosis due to alcohol abuse. CONCLUSION: Early diagnosis as well as intensive and aggressive treatment are key to successful treatment of FG. Comorbidity increases length of therapy and lowers the chance for recovery. Disease can be seen again several years after the initial outburst.

Microdochectomy in the management of pathologic nipple discharge.

BACKGROUND: There is a debate in the literature whether a pathologic nipple discharge is a distinct sign of breast carcinoma. Our own results obtained by the use of microdochectomy as a minimally invasive operative procedure in 184 patients with pathologic nipple discharge were analysed. The aim of this retrospective 20-year study was to assess the efficacy of microdochectomy in detecting early stages of intraductal breast carcinoma. PATIENTS AND METHODS: The study included data on 184 patients aged 24-77 years (median 46.6) divided into two groups of premenopausal (n = 123) and postmenopausal (n = 61) women. There were 139 patients with unilateral single-duct sanguinolent discharge and 45 patients with other types of nipple discharge. The operative procedure consisted of the discharging duct excision by use of a guide probe, preceded by cytology and ductography studies. RESULTS: Histopathology of the excised ducts revealed only three carcinomas in premenopausal women and ten carcinomas in postmenopausal women. In a total of 13 carcinomas, there were 4 ductal carcinomas in situ, detected in patients aged 41-72 (median 66) years. Twelve carcinomas were associated with sanguinolent nipple discharge. Papilloma was the most common histology finding (56.5%). CONCLUSION: Results of the study suggested mainly the association of sanguinolent single-duct nipple discharge and papilloma, whereas the rate of malignancies detected (7.0%) was consistent with literature reports. Microdochectomy proved to be a highly efficient operative method free from any impairment of the breast integrity. Conservative treatment with close clinical monitoring of the patient with cytology and ultrasonographic assessment might be possible in selected cases.

[Ileus caused by metastasis of cutaneous malignant melanoma: case report]. / Ileus izazvan metastazom koznog malignog melanoma: prikaz bolesnika.

In this case report we describe rare metastatic appearance of cutaneous malignant melanoma ( MM) in small intestine followed by clinical appearance of acute surgical abdomen. A 42-year old women operated in our hospital in April 2009. due to unusual naevus on her right arm. Pathologicaly it was MM grossly 1.5 cm, microscopically Breslow 11 mm, Clark's level IV (T4), number of mitosis 1.4 per mm2, without ulcerations. She was sent to continue treatment at the National Referal Center for Melanoma in KB "S. milosrdnice" Zagreb, Croatia. A month later wider excision (3 cm free margin) and sentinel lymph node biopsy (SLNB) was made there followed by axillary lymphadenectomy due to positive axillary finding. She received six cycles of chemotherapy. She arrived in our hospital in May 2010, under clinical picture of small intestine ileus and acute surgical abdomen. After preparation she was operated the same day. The cause of ileus was metastasis of MM in the small interstine. We made intestinal resection with termino-terminal anastomosis. The patient was released to home care ten days after operation without any complication. This case report demonstrates rarely described case of MM metastasis in the small intestine found causing ileus.

Chorangioma placentae.

Chorangioma of the placenta is a rare tumor with a frequency of about 1%, which usually presents as a solitary nodule or, less frequently, as multiple nodules. It is found on the fetal surface of the placenta or in placental parenchyma. Most chorangiomas are small and possess no clinical significance. On the contrary, clinically significant chorangiomas, greater then 5 cm or multiple, may be associated with pregnancy complications. The case presented is one of the uncommon presentations of chorangioma, in which its presence and size were not related to a pregnancy disorders or developmental anomalies of the fetus.

Phyllodes tumors of the breast diagnostic and therapeutic dilemmas.

BACKGROUND: This article compares experiences in the diagnosis and treatment of phyllodes tumors from 2 regional institutions with the relevant literature. PATIENTS AND METHODS: From 1991 to 2005, 2,848 breast cancer patients were treated in our institutions, 36 (1.44%) for phyllodes tumors. The average tumor size was 5.1 cm (range 1.4-19.6). Triple assessment was the standard diagnostic algorithm. Wide excision with tumor-free margins was carried out in 29 (80.5%) cases and mastectomy in 7 (19.4%) cases. Axillary lymphadenectomy was performed in patients with positive lymph nodes. RESULTS: Histology showed the phyllodes tumors to be benign in 27 (75.0%), malignant in 6 (16.6%), and borderline in 3 (8.3%) cases. Follow-up was from 5 months to 16 years. In this period, recurrences of 3 (8.3%) malignant and 2 (5.6%) benign phyllodes tumors were diagnosed and treated. 10 (27.7%) patients treated with wide local excision showed deformities in the form of scarring. The steroid receptor status was of no prognostic value in our patients, and chemotherapy was used in only 1 (2.7%) patient. 5-year survival was 86.2%. CONCLUSION: Our study shows that tumor size, margin infiltration, mitotic activity and degree of cellular atypia are important prognostic factors. Problems in diagnosing this condition arise from its similarity to fibroadenoma. Although wide local excision is usually the treatment of choice, tumor recurrence is common. Axillary lymphadenectomy in malignant phyllodes tumors is, in our opinion, still controversial.

The immunomodulation effect of allogenic blood transfusion in colorectal cancer--a new approach.

The total number of 542 patients with colorectal cancer surgery have been analyzed in order to estimate the effect of receiving transfusion local recurrences, and the disease free - survival. It should be examined whether there are changes in general immunity indicators which would be connected with perioperative transfusion. A significant connection has been found between local recurrences and blood transfusion (p<0.0001), the most noticeable being in Dukes A (p =0.045), localization on rectum (p=0.036). The receiving of blood transfusion is linked significantly with disease free - survival reduction (p =0.0068; log rank), the most significant being in Dukes A stage (p =0.0123; log rank) and with localization on rectum (p=0.0231). The analysis of general immunity indicators has shown significant immunocompromitation of patients just before the surgery and this could have effect on immunomodulation caused by transfusion and just as on the treatment prognosis of colorectal carcinoma.

Sexual dysfunction in breast cancer survivors.

AIM: The aim of this study was to determine differences in body image and sexuality of breast cancer survivors, depending on treatment: radical mastectomy or breast-conserving surgery. PATIENTS AND METHODS: A total of 206 patients treated for breast cancer between January 2001 and January 2004 were asked to fill in the questionnaire 1-5 years after treatment. Patients were divided into 2 groups. The first group consisted of 108 patients with advanced stages of breast cancer and who were treated with modified mastectomy with adjuvant chemo- or radiation therapy. The second group consisted of 98 patients with early stages of breast cancer who were treated with breast conserving surgery, lumpectomy and radiotherapy. RESULTS: A significant number of patients in both groups was satisfied with their sexual life before treatment, 70.37 and 73.47% respectively, which is grossly reduced after treatment of breast cancer (56.48 and 50.00%, respectively, p > 0.05). Most of patients found their partner's attitude towards them to be the same (31.48 and 45.92%), or even better (39.82 and 25.51%) after treatment, and they described them as very supportive and tender. In group 1, 58.33% of patients felt differences in their body image, in contrast to 44.90% in group 2. Similar proportions were observed in both groups for patients who felt mutilated (18.52 vs. 8.16%, p < 0.01). CONCLUSION: These findings confirm and extend previous reports of impaired sexual functioning among breast cancer survivors.

Differences in sexual functioning between patients with benign and malignant breast tumors.

The aim of this study was to compare differences in sexual behavior between patients with benign and malignant breast tumors. A total of 187 patients treated for breast tumors (benign or malignant) at the General Hospital >>Pozega<<, Croatia, filled in the questionnaire between January 2001 and May 2003. Patients were asked to fill in the questionnaire one to ten years after treatment of breast tumor, while they were on their regular control visit. Deterioration in sexual life experienced 36.27% of patients with benign tumors and 51.76% of patients with malignant tumor (p<0.01). The main reason of sex life impairment in both groups was distortion of body image perception. Most of partners did not change their behavior toward women with breast tumors (48.72% for benign group and 41.82% or malignant group, p>0.05). A great amount of women in both groups felt certain change in her >>body image<<, but in greater extent in malignant group (41.18% vs. 25.49%), (p<0.05). From our results we can see that patients in this study do not recognize need for consultation with their physician regarding sex life after treatment of tumor (41.18% for benign and 35.29% in malignant group). It can be concluded that considerable amount of attention should be given to psychological aspects of recovery which can improve prognosis and quality of life in general.

Youth and AIDS--a study of attitudes, knowledge, behavior and risks in the post-war Croatia.

According to the latest reports, the Eastern Europe currently exhibits the greatest relative increase in the number of newly registered HIV infections in the world. At the same time, Central Europe remains relatively spared from the epidemic, with reported rates significantly lower than those in both Eastern and Western Europe. Croatia geographically affiliates to Central Europe, but it has two specific potential risk factors in comparison to neighboring countries: recent War events and a summer season when immigration of large number of tourists from Central and Eastern Europe is expected. Therefore, it is critical to examine AIDS attitudes in young people, increase their knowledge, monitor their behavior and warn on risks in order to prevent larger spread of epidemics from Eastern Europe to Croatia. In this study, we report on a large related survey and education program among 17-year-old high school pupils that was conducted in years immediately following the War (1996-1999).

Effects of war aggression in Croatia on some forms and manifestations of breast cancer.

The aim of this study was to determine the differences in epidemiological and clinical manifestations of breast cancer in time of war in Croatia and in peacetime before and after the war, in the defined population of Pozesko-Slavonska County. The methods used in this study were the evaluation of relative predictive value of variables by means of chi 2-test and the analysis of variance, while the survival studies were tested by Long Rank test according to Kaplan-Meier analysis of survival. This work encompasses 660 patients who had breast cancer. The differences between three time periods were evaluated: the war period (1991-1995), and two control periods: before the war (1981-1990) and after the war (1996-2000). The patients were grouped by age, localization of tumor and survival. During the war period the patients were, on the average, 4.2 years younger than those who acquired the disease in control periods, and the mean age of patients was between 50 and 59 years (36.5% of patients). Although the difference in tumor distribution by sides (left or right breast) and quadrants was statistically significant (war period vs. control periods; p < 0.001), there was no statistically significant difference in the survival of patients according to the results of Kaplan-Meier analysis of localization of tumor (p > 0.05). The length of survival in terms of age of patients in time of surgical procedure was significantly different (p < 0.001). This study confirms the effects of war on some epidemiological and clinical manifestation of breast cancer in the defined population of Pozesko-Slavonska County.

Unilateral multicentric breast cancer.

Clinical characteristics of unilateral multicentric breast cancer (UMBC) were explored depending on aggressiveness, survival rate, disease-free period and local recurrence. The study included 296 women with breast cancer, surgically treated between 1990 and 2001. UMBC was histologically proved in 29 (9.8%) patients. Multicentricity was defined by following criteria: a) tumor with minimum one satellite node in the same or other quadrant of the breast; b) minimum one cut through the breast without tumor cells; c) histopathologically, discontinued tumors with intra-ductal invasion. The average age of patients was 63.4 (range 36-85). There were 9 (31.0%) women with one satellite node, 7 (24.1%) women with two satellite nodes, and 13 (44.8%) women with three or more satellite nodes. At the operation, axilla was positive in 20 (68.9%) women. Steroid receptors were highly positive in 12 (41.4%) patients. Primary and secondary tumors were of the same histological type in 26 (89.6%) patients. Local recurrence was found in only 3 (10.3%) patients. A five-year period without disease was achieved in 24 (82.7%) women. Kaplan-Meier analysis showed a significantly higher survival rate at lower tumor stages (I or II) unlike in advanced stages with predominantly N2 grade. The results of this study showed a slightly lower five-year disease-free period than in the case of patients with monocentric breast cancer (MOBC). The survival rate was significantly lower at all advanced stages, especially determined by N2 axilla. Therefore, the conclusion is that multicentricity doesn't increase the risk of poor prognosis, especially at lower tumor stages.

Effects of war aggression in Croatia on histopathological manifestations of breast cancer in defined population of one county.

The aim of the present study was to determine the differences in epidemiological and clinical manifestations of breast cancer during the war in Croatia and in peacetime. 660 consecutive patients were recorded (656 female and 4 male patients) from Pozesko-Slavonska County. The changes in histopathological features were recorded in war period (1991-1995, 156 patients) and through two control periods, before the war (1981-1990, 282 patients) and after the war (1995-2000, first five months, 223 patients). The relative predictive value was calculated using chi 2-test. The survival was calculated according to Kaplan-Meier analysis of survival. The histopathological analysis showed an equal distribution of noninvasive cancer (in situ cancer) across periods. In the war period, the level of the most common invasive cancer, ductal breast cancer, was lower (57.7%), compared to control periods (71.2%:63.7%:68.2%). Opposite to that, invasive lobular cancer was more common in the war period (3.2%), compared to control periods (0.7%-1.3%). Furthermore, mixed cancer was also increased in the war period (7.1%) compared to control periods (0.7%-2.2%), as was medullar cancer (10.9% vs. 5.5%-5.9%). The study showed statistically significant differences in the survival of patients with different histopathological diagnoses (Log Rank = 47.49, df = 7, p < 0.0001), while the histological grade of tumor, as a predictive factor was not proved to be statistically significant (p > 0.05). This study confirmed the influence of war of war on histopathological incidence of some forms of breast cancer.

Anthropological and clinical characteristics in adolescent women with dysmenorrhea.

The aim of this study was to examine the prevalence of dysmenorrhea in female adolescents and the influence of anthropological characteristics and lifestyle factors on menstrual pain. Two hundred and ninety seven girls from several elementary and secondary schools were interviewed about the presence of the menstrual pain, their age, height and weight, menarcheal age, menstrual cycles quality, smoking and sexual activity. There were 164 (55%) subjects with and one hundred and thirty three (45%) without dysmenorrhea. The adolescents with dysmenorrhea answered the questions about missing activities and taking pills for pain. No difference was observed between the girls with and the girls without dysmenorrhea in their chronological age, height, weight, menarcheal age, menstrual cycles quality, cigarette smoking and sexual activity. In the group of dysmenorrheic adolescents there was infrequent missing activities and bedrest, but missing school was observed in 22 percent and taking pills for pain was observed in 96 percent of the subjects. Young girls who experienced menstrual pain are good candidates for a prophylactic therapy, such as hormonal contraception. A replication of this study is needed for public health services in the future to improve the quality of life of the dysmenorrheic young women.
