Breast-conserving surgery in breast cancer.

The breast cancer treatment is based nowadays on new surgical options: breast-conserving surgery, which applies at least for the first and second stage cancer, with radical intention. We have been practicing breast-conserving surgery for the last 16 years and we have performed 303 breast conserving operations from a total of 673. We recorded 12 local recurrences (3,96%) and 2 deaths due to cancer progression. Our protocol includes removal of the primary tumor with enough surrounding tissue to ensure negative margins of the resectable specimen, associated with axillary lymph-node dissection and postoperative breast irradiation. Our oncologist indicated chemotherapy on different postoperative conditions: tumor size, axillary lymph node involvement, patient's age, etc. The purpose of this paper is to emphasize our modest experience, nevertheless to draw the attention on important results, obtained by long-term monitoring of the patients who underwent breast-conserving surgery, in a two prospective protocols, and demonstrate the importance and applicability of breast conserving therapy. The conclusion of this study is that breast-conserving surgery followed by breast irradiation is reliable, as the results are similar with radical mastectomies; the main objective is to obtain a good cosmetic result, which depends on tumor size / breast size.

[Diseases mimicking advanced-stage epithelial ovarian cancer]. / Afectiuni mimând cancerul ovarian epitelial în stadiu avansat.

This paper draws attention towards 3 cases with different pathologies all of which suggesting however both clinically and by imaging means as the most likely diagnosis advanced-stage epithelial ovarian cancer since all these three postmenopausal women had been admitted to the hospital with ascites, pelvic masses and deterioration of the physical wellbeing (fatigue, decreased appetite, weight loss, pallor). Findings during exploratory laparotomy on all these three pacients included ascites (hemorragic in one case) diffuse tumorous implants throughout the abdominal and pelvic peritoneal surfaces (in two cases) and the ovarian tumour. Postoperatively, the final histopathologic diagnoses consisted of primary peritoneal carcinoma (one pacient), peritoneal tuberculosis (TB, one pacient) and hepatic cirrosis with an incidental benign adnexial mass (one pacient). Moreover, nonmalignant ovarian tumours were certified in all three cases under current presentation. The differential diagnosis of the ovarian cancer and a tailored approach to treatment for each of these three pathologic entities will also be described in detail.

[Correlation of adenomatous polyps and early colorectal cancer. Diagnostic and therapeutic implications]. / Relatia polip adenomatos--cancer colorectal precoce. Implicatii diagnostice si terapeutice.

AIM: To detect the patients with colorectal adenomatous polyps or those with adenocarcinoma areas with a view to prevent and to treat the malignant disease. MATERIAL AND METHOD: A prospective study including 309 patients hospitalized between 2000-2005 diagnosed with isolated adenomatous polyps after repeated colonoscopies. The research method was selective screening with identification of risk factors regarding the evolution of colorectal polyps in early cancer, using colonoscopy and histopathological examination. RESULTS: We identified 464 single or multiple isolated polyps of which 399 were adenomas, 59 hyperplastic polyps and 6 other types of lesions. Histologically we recorded 41 (13.27%) polyps with a low grade of dysplasia, 56 (18.12%) with severe dysplasia and 30 (9.7%) intramucosal adenocarcinoma with submucosal invasion. TREATMENT: Colonoscopic polypectomy was used for benign polyps and in situ carcinoma. In case of adenocarcinoma is probable the invasion of submucosal lymphatics being shown a colorectal resection as appropriate. We performed 279 colonoscopic polypectomies and 30 conventional resections. CONCLUSIONS: High grade of dysplasia, the number of polyps, ulceration, bleeding, intraepithelial areas of neoplastic transformation are predictive factors for early colorectal cancer. Depth of submucosal invasion of malignant transformed polyps are important pathological factors to predict lymphatic metastasis and to select the therapeutic procedure.

EGFR, HER2÷neu and Ki67 immunoexpression in serous ovarian tumors.

In this study, we analyzed EGFR, HER2/neu and Ki67 immunoexpression for 26 benign, borderline and malignant serous ovarian tumors. EGFR and HER2/neu immunoreactions were present in some benign/borderline tumors with high/low intensity of immunostain. In poorly differentiated adenocarcinomas, the EGFR/HER2/neu reaction was intense compared to well-differentiated ones. The Ki67 medium proliferation index was 2.1% for benign tumors, 6% in the borderline and 47.7% in malignant tumors. EGFR, HER2/neu and Ki67 can be used to identify benign/borderline tumors with progression potential and the malignant aggressive tumors.
