Early Breast Carcinoma

Breast cancer is the most common malignant neoplasm in female population. The complexity of early breast carcinoma diagnostics is conditioned by the variability of the breast structure during life, as well as cyclic, hormone conditioned changes. Today, the most important and the most widely applied radiological modality is mammography, which value has been proved by many studies. Up-to-date diagnostic algorithm also includes the breast evaluation by ultrasound with the probes of 7.5 and 10 MHz that provide for high tissue resolution. Magnetic resonance currently presents the most up-to-date visualization modality. Its basic technical possibilities: multiplanarity, high area, and tissue resolution combined with biological noninvasiveness, unambiguously make MR the most sensitive and the most specific radiological method for evaluation of the majority of organism regions.

This paper presents the results of the study of various pathomorphological forms of breast tumors in the population of domestic cats of the Rostov region. 73247 case histories were analyzed in 8 leading veterinary clinics of Rostov-on-Don and Bataysk city, and also 30 resections of a breast were made with the subsequent histological research. The incidence of breast tumors in the population of cats of the Rostov region in 2018 was 438 animals per 100000. According to the results of 187 cytological findings, “malignant neoplasm” was diagnosed in 53% of cases (48% - carcinoma, 5% - sarcoma). The histological examination revealed malignant tumors in 80% of cases (77% - invasive nonspecific carcinoma, 3% – malignant leaf-shaped tumor). Taking into account the fact that about 1.5(±76 thousand) million cats live in the Rostov region, it can be assumed that 0.44% (p-95%, confidence interval 0.38%-0.50%) will have a breast tumor, about 80% (p-95%, confidence interval 55%-94%) of which will be malignant.

Breast cancer in (42-48) % of cases is a multicentric or multifocal process. Multicentricity of the tumor is the presence of several tumor foci located in different quadrants (segments) of the breast; multifocality is the presence of several tumor foci in one square or segment. Multifocal and multicentric cancers evidently are biologically different diseases. The importance of identifying all the foci is that with a multicentric lesion, more radical types of surgical treatment are applied. With cancer monocentricity, organ-preserving surgery is predominantly chosen, and with multicentricity – radical mastectomy. Multifocality not detected at the preoperative stage and, especially, multicentricity is the cause of relapses in more than 40 % of cases. The purpose of the review is to consider the information content and effectiveness of radiation diagnostic technologies in the aspect of identification of multicentric and multifocal breast cancer. X-ray mammography, full-format digital X-ray mammography, magnetic resonance imaging, multispiral computed tomography, infrared thermography of transmission optical tomography, sonography, digital tomosynthesis, mammoscintigraphy, electric impedance mammography are considered. Key words: multifocal and multicentric cancer, mammography, magnetic resonance mammography, multispiral computer tomography, mammoscintigraphy, sonography, electric impedance mammography.

Women with newly diagnosed breast cancer may have lesions undetected by conventional imaging. Recently contrast-enhanced magnetic resonance mammography (CE-MRM) showed higher sensitivity in breast lesions detection. The present analysis was aimed at evaluating the benefit of preoperative CE-MRM in the surgical planning. From 2005 to 2009, 525 consecutive women (25–75 years) with breast cancer, newly diagnosed by mammography, ultrasound, and needle-biopsy, underwent CE-MRM. The median invasive tumour size was 19 mm. In 144 patients, CE-MRM identified additional lesions. After secondlook, 119 patients underwent additional biopsy. CE-MRM altered surgery in 118 patients: 57 received double lumpectomy or wider excision (41 beneficial), 41 required mastectomy (40 beneficial), and 20 underwent contra lateral surgery (18 beneficial). The overall false-positive rate was 27.1% (39/144). CE-MRM contributed significantly to the management of breast cancer, suggesting more extensive disease in 144/525 (27.4%) patients and changing the surgical plan in 118/525 (22.5%) patients (99/525, 18.8% beneficial).

Early Breast Carcinoma

The effects of neoadjuvant chemotherapy in increasing the rate of conservative breast therapy and associated with reducing morbidity and better cosmetic has been fully acknowledged. Now, there are commonly used neoadjuvant chemotherapy for operable early breast carcinomas patients. Currently, neoadjuvant chemotherapy is used for locally advanced breast carcinoma, inflammatory breast cancer, and down staging of the large tumor to allow for breast conservative therapy. A prospective study performed in the department of surgery in Al-Sadder Medical City/Najaf city/Iraq, from the …….. of October 2015 to the 1st of October 2018, where 48 patients presented with a breast cancer diagnosis by clinical examination, Mammography, breast ultrasound, chest x-ray, bone scan, serum CEA, CA15_3 level, the initial diagnosis of breast cancer made by core needle biopsy. Breast saving surgery consisted of wide local excision with a safe margin with standard level I, II lymph node of axilla dissection. The resected specimen and lymph node was sent for histopathological examination; the size, width, length &height dimension were recorded and the resection margin was recorded positive if close to 2mm and negative if >2mm tumor-free margin. The 48 patients enrolled in this study with a mean age at diagnosis of 44.6 ± 8.4 years. 34 patients received neoadjuvant chemotherapy, Locoregional recurrence reported in 4 patients (28.6%) not received neoadjuvant chemotherapy (P. value < 0.001), the higher relapse rate was reported significantly in the cases aged more than 50 years compared to those aged 50 years or below (P. value = 0.05, significant). Neoadjuvant chemotherapy decreases the incidence of locoregional recurrence of early breast carcinoma after breast-conserving surgery.
