Loss of heterozygosity and copy number alterations in flow-sorted bulky cervical cancer.

Treatment choices for cervical cancer are primarily based on clinical FIGO stage and the post-operative evaluation of prognostic parameters including tumor diameter, parametrial and lymph node involvement, vaso-invasion, infiltration depth, and histological type. The aim of this study was to evaluate genomic changes in bulky cervical tumors and their relation to clinical parameters, using single nucleotide polymorphism (SNP)-analysis. Flow-sorted tumor cells and patient-matched normal cells were extracted from 81 bulky cervical tumors.

Patterns of parametrial involvement in radical hysterectomy specimens of cervical cancer patients.

A tumor in the parametria, either continuous with or separate from the primary malignancy, is an unfavorable prognostic factor in cervical cancer. The incidence of a parametrial tumor localized in blood or lymph vessels, or in tissue, and the relationship of these involvement patterns with pathologic characteristics and prognosis were investigated. Seventy-nine of 763 surgically treated cervical cancer patients (10%) had a tumor in the parametria in hysterectomy specimens.

Abdominal scar recurrences of cervical cancer: incidence and characteristics: a case-control study.

Background: Tumor recurrence in the surgical scar after radical hysterectomy for cervical cancer has been reported, but the incidence is unknown. Facts about patient and tumor characteristics and follow-up are lacking. The objective of this study was to analyze the incidence and characteristics of cervical cancer scar recurrences.

Nerve-sparing radical hysterectomy: local recurrence rate, feasibility, and safety in cervical cancer patients stage IA to IIA.

Unlabelled: To clarify the debate about the possible threat of sparing the pelvic autonomic nerves in radical hysterectomy for cervical cancer to radicality, comparative studies of nerve-sparing and conventional surgery are necessary. The aim of his study was to analyze and compare local recurrence rate, feasibility, and safety of nerve-sparing and non-nerve-sparing radical hysterectomy.

Methods: In a cohort study with 2 years of follow-up, 246 patients with cervical cancer of stages IA to IIA were analyzed: 124 in the non-nerve-sparing group (1994-1999) and 122 in the group where nerve-sparing was the intention-to-treat (2001-2005).
