[Umbilical metastasis from malignant neoplasms of pelvic and abdominal cavity with 3 cases analysis].

OBJECTIVE: To study the incidence, spreading path, prognosis and treatment of the umbilical metastasis Sister Mary Joseph nodule (SMJN) from malignancies. METHODS: To analyse the clinical feature from 3 cases of SMJN and to review pertinent literatures. RESULTS: Three cases SMJN were come from advanced primary peritoneal carcinoma in case 1, recurrent mucinous ovarian papillary adenocarcinoma in case 2 after primary cytoreductive surgery and systemic chemotherapy and case 3 with recurrent endometrial carcinoma. All patients received umbilical resection and the umbilical metastasis was confirmed pathologically, while case 3 was diagnosed adenocarcinoma spreading by fine needle respiration before the surgery. The mean survival was 63 months following surgery or chemotherapy or radiotherapy, case 1 died of advanced malignancy, while case 2 and case 3 were still alive 58 and 44 months, respectively. CONCLUSIONS: Although the incidence being low, SMJN was the important sign of one of the vast metastatic malignancy and has grave prognosis. Umbilical resection should be performed on some patients of SMJN with relative good condition, and chemotherapy or radiotherapy should also performed accordingly.

Pathways of nodal metastasis from pelvic tumors: CT demonstration.

Although the normal pathways of lymphatic drainage from the pelvic organs have been well described in the anatomy literature, the pathways of nodal metastasis from individual pelvic neoplasms are not well illustrated in the imaging literature. The authors retrospectively reviewed computed tomographic scans of the abdomen and pelvis in patients with various pelvic neoplasms, including those of the ovary, testis, prostate, cervix, bladder, anorectum, and other sites, to define the pathways of nodal metastasis. In most patients, pathways of nodal metastasis correlated well with the normal lymphatic pathways described in the anatomy literature, including the superficial inguinal pathway; the anterior, lateral, hypogastric, and presacral routes of the pelvic pathway; and the paraaortic pathway. However, there also were various uncommon pathways of nodal metastasis, such as metastasis along the gonadal vessels, mesenteric and mesocolic nodes, posterior iliac crest nodes, and inferior phrenic nodes. Understanding these common and uncommon lymphatic pathways of metastasis will help radiologists detect disease spread from pelvic tumors.

Computed tomography of pediatric urinary tract disease.

Computed tomography (CT) has considerable value in imaging abnormalities of the urinary tract in children. The advantages, indications, techniques, radiation dosage, and future of pediatric abdominal CT are presented. Computed tomography of Wilms' tumor, neuroblastoma, pelvic neoplasms, renal lymphoma, perirenal inflammatory disease, and renal trauma is discussed and illustrated.

A pharmacokinetic model and the clinical pharmacology of cis-platinum, 5-fluorouracil and mitomycin-C in isolated pelvic perfusion.

PURPOSE: An isolated pelvic perfusion technique using multiple agents was used both in patients with unresectable recurrent pelvic neoplasms and as a preoperative therapy for advanced pelvic malignancy. METHODS: The technique consisted of vascular occlusion via transfemoral balloon catheters, circulation and drug infusion using standard hemodialysis technology, and a 45-min isolation period. Blood and urine samples were analyzed for the levels of cis-platinum (17 patients, 21 courses of therapy, 50-100 mg/m2, infusion 0-10 min), 5-fluorouracil (12 patients, 14 courses, 1500 mg/m2, infusion 1/3 dose 0-1 min, 2/3 dose 1-20 min) and mitomycin-C (11 patients, 14 courses, 10-20 mg/m2, infusion 10-20 min). An empirical, four-compartment pharmacokinetic model was developed to establish drug distribution curves for the pelvic and systemic circulations and to yield valid estimates of the pharmacokinetic parameters. RESULTS: Pelvic isolation of drug was demonstrated by the pelvic-systemic drug exposure ratios of 6.0:1 for cis-platinum, 8.4:1 for 5-fluorouracil and 9.0:1 for mitomycin-C. Isolation at the L3-4 interspace resulted in minor urine drug elimination during isolation (cis-platinum 7.2% of drug, 5-fluorouracil 2.4% and mitomycin-C 2.5%). Because drug infusion was limited to the first 20 min of isolation, drug levels at the end of the isolation period were reduced to the extent that no extracorporeal drug removal mechanism was needed. CONCLUSION: These pharmacokinetic results indicate that this isolation technique has the potential to provide increased therapeutic indices and is a suitable system for evaluating fast-acting highly toxic experimental drugs to human pelvic cancers which are poorly responsive to conventional clinical protocols.
