14577 Background: Presence of bone marrow micrometastases (BMM) is an important prognostic factor for patients (pts) with solid tumors. Sentinel lymph node (SLN) mapping (M) has been found to upstage pts with gastrointestinal (GI) malignancies. However, a direct correlation between the presence BMM and nodal metastases (mets) is lacking. Hence, a retrospective study was undertaken to determine the relationship between BMM and nodal status in various GI malignancies. Methods: A total of 159 consecutive pts with GI malignancies were analyzed. Of these, 6 pts with non-epithelial tumors were excluded. All pts underwent bilateral posterior-superior-iliac spine bone marrow (BM) aspiration. BM samples were examined for micrometastases by Automated Cellular Imaging System using ChromaVision Cytokeratin Detection Kit to detect cells expressing CK8 as defined by CAM 5.2 monoclonal antibody. When feasible, SLNM was performed followed by standard oncologic resection (n=105). The SLN were examined by H&E and immunohistochemical (IHC) staining. Results: A total of 153 pts were analyzed in the study. Of these 13.72% (21/153) were found to have BMM (CI 8.70–20.21, p=0.05). When analyzed by sites, the incidence of BMM was 33.3% (4/12) for stomach cancer, 9.1% (1/11) for pancreatic cancer, 12.36% (11/89) for colon cancer and 16.13% (5/31) for rectal cancer. No BMM were detected in pts with cancer of esophagus (n=7), small bowel (n=2) and liver (n=1). The BMM was positive bilaterally in 61.9% (13/21), and unilaterally in 38.1% (8/21). In pts who underwent SLNM (n=105), BMM were detected in 11.11% of SLN positive pts vs. 10.14% for SLN negative pts (p=0.87). For a subgroup of pts with colorectal cancer who underwent SLNM (n=97), BMM were detected in 9.67% of SLN positive pts vs. 9.09% for SLN negative pts (p=0.92) Conclusions: BMM did not correlate with nodal status for GI malignancies suggesting a possible different mechanism for metastases. Detection of BMM may have a significant clinical value in SLN negative pts who may benefit from adjuvant therapy. [Table: see text] No significant financial relationships to disclose.

Bone marrow aspiration examination is performed mainly to evaluate haematological disorders. Several bone marrow aspiration needles are available that include the Salah, Klima, Jamshidi and Islam. However, cost is an issue in our local environment as most of our patients are not medically insured. We describe our experience of bone marrow aspiration using an 18-gauge lumbar puncture needle at the posterior superior iliac spine. The technique is safe and cost effective and the site is easily accessible, even in obese patients. The crush preparations provide good morphology, therefore avoiding repeats. Additional training is not required for the procedural technique. We recommend this technique for use in resource challenged settings.

The Relationship

Abstract Background: The spinal level determined by reference of posterior superior iliac spine (PSIS) will be different because of the various sagittal posture of spine-pelvis complex. The study aimed at investigating the anatomical factors affecting the estimated spinal level of PSIS from the standpoint of spine-pelvis paraments, and provided a basis for improving the accuracy of positioning. Methods: The lumbar X-ray images of 76 patients were retrospectively analyzed. The population was classified according to the estimated level of PSIS. lumbar lordosis (LL), sacral slope (SS), pelvic incidence (PI), pelvic tilt (PT) and other parameters were measured. Then, the latent factors affecting the estimated level were filtered and obtained by One-way ANOVA and Fisher linear discriminant analysis to further summarize the imaging characteristics of different populations. Results: Three different levels of L5 (10 cases), S1 (46 cases) and S2 (20 cases) were observed. ANOVA analysis showed that LL, SS, PT, PI, SS-PT, LL-SS and lordosis of L1-L5 (LL L1-L5 ) were significantly different among the three groups ( P < 0.05). Discriminant analysis showed that LL, SS, SS-PT and LL L1-L5 were the main factors affecting the estimated level of PSIS (P < 0.05). Conclusions: The variations of morphological parameters such as LL, SS, SS-PT and LL L1-L5 can affect the estimated level of PSIS, and the level can be predicted by the discriminant function. In the study, the function is D=-4.458+0.13×LL-0.115×SS+0.45× （SS-PT）+0.39×LL L1-L5 , which proved 71.1％ of the discriminant accuracy rate.

Background Traditional methods for approaching the lumbar plexus from the posterior rely on finding the intersection of lines that are drawn based on surface landmarks. These methods may be inaccurate in many cases. The aim of this study was to determine the accuracy of these traditional approaches and determine if modifications could increase their accuracy. Methods The lumbar plexus region of 48 cadavers (78 +/- 7 yr; 167 +/- 6 cm; 60 +/- 13 kg; men/women: 29/19) was dissected, and relevant anatomic structures were marked. Needle proximity curves were obtained by triangulation for the five traditional approaches and for vectors from the posterior superior iliac spine directed towards the lumbar spinous processes of L3 and towards L4. Results Proximity curves (mean +/- SD) showed that except Pandin's approach (13 +/- 5 mm too medial), all others were too lateral: Winnie (17 +/- 8 mm), Chayen (8 +/- 5 mm), Capdevila (6 +/- 4 mm), and Dekrey (17 +/- 6 mm). Further, the curves had a narrow parabolic shape and thus a narrow margin of error. Both diagonal vectors had a significantly higher proximity to the lumbar plexus as compared with traditional approaches with a wide parabola, indicating more error tolerance. Using the vector posterior superior iliac spine-L3 with a length between 1/6-1/3 (= 16-22 mm) of the distance posterior superior iliac spine-L3, a proximity to the lumbar plexus &lt; 5.0 +/- 0.3 mm was reached. Conclusion Improvement of both the proximity and the margin of error is possible by using diagonal landmark vectors. Relying on the position of the posterior superior iliac spine eliminates the sex and sided differences and individual body size, which can be problematic if firm metric distances are used in determining the entry point.
