[Ductal carcinoma in situ (DCIS) and biopsy of the sentinel lymph node]. / DCIS a biopsia sentinelovej uzliny.

INTRODUCTION: Ductal carcinoma in situ (DCIS) is the disease with increasing incidence. Nowadays, approximately 80% DCIS are diagnosed via mammography and represent more than 20% of all types of breast cancer. The acceptance of surgical procedures with this type of breast carcinoma is controversial as primary diagnosis of non-invasive carcinoma is often underestimated and in the end, histopathological examination reveals invasive carcinoma with biological potential to metastasize. In cases of "risk" patient groups with DCIS, several studies report lymph node metastases. The aim of the study has been to assess the incidence of sentinel lymph node metastatic involvement in high-risk patient group with DCIS and in ductal carcinoma in situ with microinvasion (DCISMI), to note the incidence of invasive carcinoma in definitive histopathology in patients with pre-operative diagnosis of DCIS and to analyze some predictors of invasivity. STUDY TYPE AND PATIENT GROUP: In retrospective analysis, we evaluated the setting of 119 patients who have been operated on at our Clinic from January, 1st 2008 until December, 31th 2010 for the diagnosis of DCIS. Prospectively, we have created the setting of 44 patients with high-risk DCIS with sentinel lymph node biopsy (SLNB) performed. METHODS AND RESULTS. Metastatic involvement of sentinel lymph node in high-risk DCIS has been found in 4 cases (9.0%)--in 1 patient (2.2%) with correct diagnosis of DCIS and in 3 patients (6.8%) with invasive carcinoma according to final histopathology. In the patient with DCIS, a micrometastasis of 0.4 mm was found in one sentinel lymph node. After complete axillary dissection, non-sentinel axillary lymph nodes metastatic involvement was not demonstrated (14/0). In 6 cases (5.0%), we identified DCISMI and did not find metastasis in sentinel lymph node. In the high-risk DCIS group, in 4 patients (9.0%) DCISMI and in 12 patients (27.2%) invasive carcinoma was found after definitive histopathologic examination. In this group, the overall ratio of invasive lesions was 36.2%. As for predictors of invasivity, high-grade carcinoma (OR 4.2; 95% CI 1,40-12,58) has more than 4-fold higher influence and lesion size

INTRODUCTION: Total thyroidectomy (TTE) with central compartment lymphonodes (LU) dissection remains a standard procedure in the treatment of differentiated thyroid carcinomas. METHODOLOGY: The retrospective study assessed a group of patients undergoing primary or secondary procedures in our clinic. PATIENT GROUP: From 01.01. 2005 to 31. 07. 2007, a total of 50 patients underwent primary procedures, TTE with dissection of central compartment lymphonodes was performed in 18 patients, 58 patients were reoperated for relapses of the disorder. In the primary procedures, the central compartment lymphonodes were affected with increased rate, proportionally to a T-stage of the disorder 28% (T1), 52 (T2), 58% (T3). Multifocal carcinoma was associated with a high risk, where metastatic lymphadenopathy occured in 53% of the cases. In the reoperated subjects, relapses of the disorder were recorded in 78% of the patients in their central compartment lymphonodes and their thyreoglobulin levels decreased. Out of 126 patients, paresis of the nervus laryngeus reccurens was recorded in 4 subjects (3.1%) and postoperative hypoparathyreosis in 14 subjects (11%). CONCLUSION: Dissection of lymphonodes is a standard part of the surgical management of differentiated carcinomas, providing local control of the disease. 78% of the relapses were located within the central compartment. Risk and complication rates correspond to those reported in total thyroidectomy.

[Completion of total thyroidectomy for a differentiated thyroid carcinoma]. / Dokoncenie totálnej tyreoidektómie pre diferencovaný karcinóm stítnej zl'azy.

Total thyroidectomy with dissection of the central compartment (CK) lymphatic nodes is a standard surgical procedure in differentiated thyroid carcinomas. A minority of the patients are diagnosed postoperatively. Our study reports on surgical tactics in these patients. During 2003-2006, 47 patients were operated, to have total thyoidectomy performed. The patients' data were assessed retrospectively.

Is local excision due to rectal carcinoma a safe operation?

Though the treatment of patients with polypoid lesions of rectum is most frequently based on endoscopic approach, there are many cases that cannot be solved endoscopically and therefore must be treated by surgeons. In the past there were several possibilities of how to operate. In reachable localisations even local operation could be performed, however with varying measures of local recurrences and survival. The aim of this article is to draw attention to the complex topic of local excisions for rectal neoplasms and at the same time to analyse the review of indication criteria and evaluate the drawbacks of this operative method in our conditions (Tab. 3, Fig. 1, Ref 14).
