To clarify the characteristics related to long-term survival in patients with lateral nodal involvement. ⋯ For patients with lateral involvement, the most important prognostic variables are distant metastases, the total number of nodes involved, circumferential margin involvement, and age. Selection of patients based on these variables may lead to the identification of a subgroup for whom lateral nodal dissection could be the first treatment choice.

To assess the distribution and type of nerve fibers present in human peritoneal adhesions and to relate data on location and size of nerves with estimated age and with clinical parameters such as reports of chronic pelvic pain. ⋯ This study provides the first direct evidence for the presence of sensory nerve fibers in human peritoneal adhesions, suggesting that these structures may be capable of conducting pain after appropriate stimulation.
-
To evaluate the need for a preoperative tumor biopsy of liver lesions suspicious for hepatocellular carcinoma (HCC). ⋯ Preoperative diagnosis of HCC was highly accurate in lesions larger than 3 cm. Tumor biopsy is unnecessary in these patients. However, in a subgroup of patients with lesions less than 3 cm, particularly those with alpha-fetoprotein levels less than 100 ng/mL, there is a higher false-positive diagnostic rate, and tumor biopsy should be considered.
-
To establish selection criteria for reoperation in patients with peritoneal dissemination from appendiceal malignancy. ⋯ Follow-up of patients treated for peritoneal dissemination from neoplasms of appendiceal origin is indicated. Selected patients in whom recurrence develops are candidates for repeat cytoreductive surgery plus intraperitoneal chemotherapy with curative intent.
