RESUMO

<p><b>OBJECTIVE</b>To report our primary experience with immediate breast reconstruction using laparoscopically harvested omental flap after breast-conserving surgery. The safety, feasibility, and clinical effect are also evaluated.</p><p><b>METHODS</b>From Jun. 2010 to Jan. 2011, 5 cases who underwent immediate breast reconstruction using laparoscopically harvested omental flap after breast-conserving surgery were retrospectively analyzed. The operative duration, postoperative days in hospital, complication and therapeutic effect were reviewed.</p><p><b>RESULTS</b>All the patients were treated successfully without laparotomy. The average operative duration was 310 min, including 60 min for harvesting the omental flap. The median postoperative days in hospital was 8 days (ranged, 5-9 days). One case complained of slight pulled feeling in upper abdomen. No other complication happened. The cosmetic result of reconstructed breasts was satisfactory.</p><p><b>CONCLUSIONS</b>The immediate breast reconstruction using laparoscopically harvested omental flap is safe and feasible with less morbidity in donor sites and good cosmetic effect. It is one of the ideal methods for immediate breast reconstruction.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the effects of sodium hyaluronate on the growth and adhesion of colorectal cancer cells.</p><p><b>METHODS</b>Human colorectal cancer cell lines SW620 and Colo205 were treated with sodium hyaluronate (25 -2,500 microg/ml), and cancer cell proliferation was measured by MTT assay in vitro. Flow-cytometric analysis was applied to detect expression of CD44 on SW620 and Colo205 cells.</p><p><b>RESULT</b>In vitro sodium hyaluronate enhanced proliferation of Colo205 cells, but it had no appreciable effect on SW620 growth under the same doses, Meantime, CD44 expression on cancer cells decreased compared with controls.</p><p><b>CONCLUSION</b>In vitro sodium hyaluronate has different effects on growth of different colorectal cancer cell lines, but can inhibit CD44 expression of colorectal cancer cells and influence their ability of adhesion.</p>

RESUMO

<p><b>OBJECTIVE</b>To study intra-operative radionuclide lymphatic mapping in sentinel lymph node (SLN) biopsy of breast cancer.</p><p><b>METHODS</b>Forty-two breast cancer (diameter </= 5.0 cm) patients with clinically negative axillary node were analyzed. 18.5 MBq/0.5 ml technetium-99m labeled sulfur colloid (labeling yield > 98%, size of colloid granule 100 approximately 200 nm) was injected into the mammary tissue around the tumor or biopsy site at four points. SLN in breast cancer was detected and dissected with the help of lymphoscintigraphy and intra-operative gamma probe. Routine lymph node dissection was performed for all patients.</p><p><b>RESULTS</b>The detection rate was 88.1% in lymphoscintigraphy and 97.6% in intra-operative gamma probe detection for SLN in breast cancer. The sensitivity, accuracy, false negative and specificity of SLN biopsy were 93.3% (14 in 15), 97.6% (40 in 41), 6.7% (1 in 15) and 100% (26 in 26).</p><p><b>CONCLUSION</b>Sentinel lymph node in breast cancer, detected by preoperative lymphoscintigraphy combined with intra-operative gamma probe, is able to predict regional lymph node metastasis. The successful rate of SLN biopsy can be raised by improvement in the quality of nuclear imaging agent, technic of injection and method of measurement.</p>
