[Advances in lymphadenectomy in colorectal carcinoma--lymphatic mapping].

AIM: The aim of this study is to evaluate the lymphatic mapping method during the colorectal carcinoma surgery and to increase a number of the detected lymphonodes up to the level of the internationally recommended standards. METHODOLOGY: In the group collected in 2002 and 2003, the lymphatic mapping method was applied in cases of 32 patients suffering from the colorectal carcinoma, according to the protocol. RESULTS: In the group of 32 patients suffering from all stages of the colorectal carcinoma, a total number of 408 lymhonodes was examined, which is 12.75 lymphonodes per patient, on average. Out of this, in the rectal carcinoma cases--7.85 lymphonodes per patient were detected on average, and in the group of the colon tumors--13.72 lymphonodes per patient. CONCLUSIONS: The retrospective evaluation of the patients who underwent surgery for the colorectal carcinoma proved the method of the lymphatic mapping to increase the number of the detected lymphonodes from 6-8 up to nearly 13. Thus, the average number of the examined lymphonodes already complied with the international oncosurgical criteria. The lymphatic mapping technique proved to significantly increase the number of the examined lymphonodes and to improve the colorectal carcinoma patients staging.

[Lymphadenectomy in the early gastric carcinoma].

AIM: The method of extended lymphadenectomy in the early gastric carcinoma treatment remains controversial. The aim of this prospective study is to assess the above method feasibility with acceptable rates of complications, in our conditions. METHODOLOGY: From 2000 to 2003, 11 patients with early carcinomas of the stomach were treated using the method of extended lymphadenectomy. The study group included 7 males and 4 females. RESULTS: In 6 cases, the tumors were located in the distal, in 4 cases in the middle and once in the proximal third of the stomach. In a single case, the IIIA stadium was concerned, the other cases were rated lower. In total, 205 lymphonodes measuring 18.6 on average (median of 16) were examined. The total of 5 lymphonodes were malignant, all of them were found in one patient. The method of the sentinel lymphonode biopsy was applied once. A cardiopulmonary complication was reported once, a punction of the subphrenic absces was reported once, a primary disorder causing a death was reported once and the patient concerned exited after a 14-month-period of his follow-up. Once, a local relaps of the disorder was reported 43 months after the procedure. The follow-up median was 27 months. CONCLUSION: The method of extended lymphadenectomy can be conducted even in our conditions with acceptable rates of complications.

[Mini-invasive radiation-navigated parathyreoidectomy--MIRP].

AIM: The aim was to introduce a new surgical method and to verify its validity. METHODOLOGY: In 20 patients whose ultrasound findings correlated with the MIBI scintigraphic results, a radiation-navigated parathyreoidectomy using a C-Track was conducted, following a radionucleotide application. RESULTS: From 2001 to 2003, 20 patients with hyperparathyreosis were operated. In all cases, an altered parathyroid gland with increased activity was detected using radionavigation. After the surgery, the calcium and the parathormone blood levels decreased. CONCLUSION: The MIRP is a miniinvasive surgical method indicated for the use in cases when hyperparathyreosis is confirmed and the ultrasound findings correlate with the MIBI-scintigraphic findings.

[Sentinel lymph node biosy in surgical treatment of breast carcinoma: prospective study].

OBJECTIVE: Authors report the validity and accuracy of lymphatic mapping with sentinel node biopsy in patients with early breast cancer between 1998 and 2000. TYPE OF STUDY: Prospective study. LOCATION: Department of Surgery, Atlas Hospital Zlin. METHODS USED: Lymphatic mapping and sentinel node biopsy using patentblue in patients with breast cancer was performed between 1998 and 2000. Combination of patentblue and radiocoloid Nanocoll Nycomed Amersham has been used from 2000. C-Track device (Care Wise Medical Product Morgan Hill) was applied for detection of radiocoloid in sentinel node. Gamma probe intraoperatively localised sentinel nodes. Lymphoscintigraphy was performed routinely. Patients were tested with routine hematoxylin & eosin staining. When the H&E staining in sentinel nodes was negative the immunohistochemical procedure was used. Following identification of sentinel nodes, axillary node dissection was applied. Axillary node dissection was abandoned by patients with tumor T1 and sentinel node negative. RESULTS: In 124 cases, the sentinel node was successfully identified. 122 patients were women with unilateral and one woman with bilateral cancer. 1 was a male. Of these 124 cases 60 were node-positive and sentinel nodes metastasis was in 26 cases only. 1375 nonsentinel nodes were examined (a mean 13.4). 268 sentinel nodes were examined (a mean 2.2). Hematoxylin and eosin staining was used routinely and if no tumor was identified then imunohistochemical cytokeratin staining was performed. Imunohistochemical staining was used in 21 cases. Only in one patient micrometastases were identified. Three sentinel nodes were negative in patient with axillary disease. CONCLUSION: This study demonstrates that sentinel node biopsy in patients with early breast cancer is safe and highly accurate an can be used to avoid axillary lymph node dissection.

[Sentinel nodes in breast carcinoma].

The authors summarize literary data on contemporary knowledge and development of views regarding lymphadenectomy in breast cancer. They deal also with the history and technique of detection of a sentinel node by Patentblau and radioisotope 99mTc. In a group of 29 patients operated in 1998-1999 with a detected sentinel node they analyze the surgical technique and present their initial results. In the group they extirpated and examined a total of 354 axillary nodes, i.e. on average 12.2 nodes per patient. Eleven times the nodes were positive, incl. the sentinel node. This number comprised six cases where the sentinel node only was affected. In 16 cases all axillary nodes were negative. In two instances the sentinel node was falsely negative. These results are thus quite comparable with those from reknown departments concerned with sentinel nodes. Examination of the sentinel node very probably determines the affection of axillary nodes and the patient's prognosis. Unnecessary dissection of the axilla with subsequent associated complications can thus be avoided.

[Results of conservative therapy in early breast carcinoma].

The authors present a review on the development of views on breast cancer from the beginning of the century and contemporary views on the problem, its solution world-wide and in the Czech Republic. They base on their own group of 475 patients of 1991-1998, they analyze the development of possible solutions of early breast cancer and their view on the discussed problem. With regard to favourable results they advocate progressive breast preserving operations associated with postoperative radiotherapy and the use of the method of sentinel nodes.

[1000 thyroidectomies--personal experience and results].

The authors made one thousand thyroidectomies in the course of five years. In the submitted paper they discuss indications, for surgery, the extent of the operations, the results of the histological findings. They describe the surgical procedure, required preoperative examinations and postoperative monitoring. They analyze different postoperative complications incl. their frequency in the discussed group. They emphasize a physiological surgical technique, verifications of the recurrent nerve, care of the parathyroid bodies and collaboration with endocrinologists.
