Vascular endothelial growth factor-C (VEGF-C) is considered to be a specific factor promoting lymphangiogenesis. There have been reports of a positive correlation between local recurrence of rectal carcinoma and lymphatic invasion by the tumor. The aim of this study was to determine the clinical significance of VEGF-C expression for identifying lymphangiogenesis as a predictor of the local recu...

Background. Early onset colorectal carcinoma (CRC) is rare and has been hypothesized to be a biologically and clinically distinct entity personifying aggressive disease and worse survival. Methods. Data for 131 patients was collected by retrospective chart review. Cox proportional hazard model was used to compute prevalence ratios and 95% confidence intervals. Results. Early onset sporadic CRC ...

We present the case of a 72-year-old woman with invasive lobular breast carcinoma, stage IV (vertebral metastasis), and with recent-onset constipation. Digital rectal examination revealed increased consistency of the rectal wall. Laboratory test showed only elevation of CEA-II (28'3). Rectoscopy showed a partial stenosis of the rectal lumen, extending from the internal anal margin to about 10 c...

Although diverticular disease of the colon is common, the occurrence of rectal diverticula is extremely rare with only sporadic reports in the literature since 1911. Symptomatic rectal diverticula are seen even less frequently, and surgical intervention is needed for only complicated cases. Here we report the case of a 63-year-old woman presenting with rectal diverticulitis mimicking rectal car...

Rectal perforation is uncommon in ovarian cancer, even in advanced stages. Pure primary ovarian squamous cell carcinoma is a very rare subtype of ovarian cancer and has not been reported to cause rectal perforation. A 50-year-old woman presented with rectal bleeding. Rectosigmoidoscopy suggested perforation of a pelvic tumor into the rectum. Abdominopelvic magnetic resonance imaging revealed a ...

BACKGROUND/AIMS This study investigated appropriate level of upward lymph node (LN) dissection in advanced lower rectal carcinoma. METHODS A total of 285 consecutive patients with stage II/III lower rectal carcinoma were analyzed. LN dissection was classified as follows: division of the root of the superior rectal artery (UD2), division of the root of the inferior mesenteric artery (UD3) and ...

PURPOSE Adequate preoperative staging of large sessile rectal tumors requires identifying adenomas that already contain an invasive focus, specifically those that are growing in or beyond the submucosa. We systematically compared chromosomal instability patterns in adenoma and carcinoma fractions of the same lesion to assess specific steps in rectal tumor progression. EXPERIMENTAL DESIGN We a...

A case of synchronous carcinoma of the accessory mammary gland and primary breast lymphoma with subsequent rectal carcinoma has not been reported previously. We present a very rare case of primary non-Hodgkin lymphoma of the left breast diagnosed simultaneously with invasive lobular carcinoma of the left axillary accessory mammary gland and rectal adenocarcinoma. An 82-year-old Japanese woman p...

Endometrial carcinoma is the most common neoplasia of female genital tract. The prognosis of early stage disease (FIGO I and FIGO II) is excellent: recurrence after surgery is less than 15%, most of which are reported within 3 years after primary treatment. Herein we report a case of late rectal recurrence from FIGO Ib endometrial adenocarcinoma. Patient had also familiar and personal history o...

The primary aim of this study was to investigate the relationship between contrast-enhanced ultrasonography (CEUS) imaging parameters and clinicopathological features of rectal carcinoma and assess their potential as new radiological prognostic predictors. A total of 66 rectal carcinoma patients were analyzed with the time-intensity curve of CEUS. The parameter arrival time (AT), time to peak e...
