Hydrocele of the canal of Nuck, also called the “female hydrocele,” is a rare developmental disorder in females. This entity is now believed to be more common now in comparison with previous reports; however, it is still an unfamiliar problem for physicians. The processus vaginalis accompanies the round ligament through the inguinal canal into the labium majus. This evagination of the parietal peritoneum forms the canal of Nuck in the female. The canal of Nuck normally loses its connection with the peritoneal cavity during the first year of life, but can result in a hernia or hydrocele when the connection of the canal of Nuck fails to close. Here, we present the case of a 43-year-old female who complained of swelling in the right inguinal region. Coronal and axial magnetic resonance imaging (MRI) revealed a cystic mass lesion with an irregular shape in the right inguinal region, and smaller cystic lesions extending alongside the right round ligament were also identified in the right side of the pelvic cavity. Magnetic resonance (MR) hydrography revealed the uninterrupted cystic lesion from the inguinal region to the pelvic cavity, with constrictions at the internal and external inguinal rings. These MR findings proved to be incredibly useful for surgical planning.
VEGF score was a significant parameter of peritoneal recurrence. Conclusion. These results suggested that VEGF was correlated with peritoneal metastasis from gastric cancer, and that VEGF was a useful indicator of peritoneal recurrence.
The purpose of this study was to clarify extended indication criteria of endoscopic mucosal resection (EMR) for early gastric cancer (EGC) by analyzing the independent risk factors involved in lymph node metastasis (LNM). Subjects were 422 patients who underwent gastrectomy with lymph node dissection for EGC at the Kurume University Hospital from 1994 to 2001. The EGCs were mucosal cancers (M) in 252 cases and submucosal cancers (SM) in 170 cases. Twelve clinico-pathological factors were assessed for their possible association with LNM. On univariate analysis, EGC with LNM showed the following characteristics: size; 3.1 cm or more, ulceration; present, heterogeneity; present, differentiation; poor, lymphatic vascular invasion; present, and invasion depth; SM2 (cancer penetration of submucosal layer, 0.5 mm or more from the muscularis mucosa). On multivariate analysis, the following four factors were identified as independent risk factors; invasion depth: Odds Ratio (OR) 10.9, lymphatic vascular invasion: OR 10.6, size: OR 3.2, and ulceration: OR 3.2. The incidence of LNM was 0% (0/141) (95% confidence interval, 0-2.6%) when these risk factors met the following four conditions: invasion depth; M or SM1 (cancer penetration of submucosal layer, less than 0.5 mm), lymphatic vascular invasion; absent, size; 3.0 cm or less, and ulceration; absent. It is concluded that EMR is a suitable radical treatment for EGC, and that the indication criteria for EMR can be extended depending on the results of the histological evaluation of the en bloc/total resected specimen concerning the above four factors for LNM.
Immune recognition of human cancers except melanoma is not well understood at either the cellular or the molecular level. We demonstrate in this study the existence of HLA class-I-restricted and tumor-specific CTL in IL-2-activated TIL (tumor-infiltrating lymphocytes) of all 4 gastric cancer patients tested. We established HLA A2-restricted and adenocarcinoma-specific CTL in 2 HLA A0201 1 patients, and HLA A2402-restricted CTL recognizing both adenocarcinoma and squamous-cell carcinomas (SCC) in the 2 remaining HLA A2402 1 patients. Further, HLA A3101-restricted and adenocarcinoma-specific CTL were established in 1 of the 2 HLA A2402 1 patients who had HLA A3101 allele. HLA A2-, A2402-and A3101-restricted CD8 1 CTL clones were established from these parental CTL lines. The 2 HLA A2-restricted CTL lines lysed 8 of 13 HLA A2 1 adenocarcinoma cell lines established from different organs (stomach, colon, lung and breast) with different subtypes (HLA A0201, A0206 and A0207). The HLA A2-restricted CTL line recognized 9 and 6 different HPLC fractions of peptides eluted from the HLA A0201 1 breast and HLA A0201 1 colon adenocarcinoma cell lines, respectively. Allele-specific deletion of HLA A2 or A24 molecules was observed in some tumor lines that were not susceptible to lysis by the CTL lines. These results suggest that TIL of gastric cancer possess CTL recognizing different peptide antigens binding to different HLA-A alleles that are widely expressed on adenocarcinomas and also, to some extent, on SCC from different organs.
