Examination of tumor samples obtained after laparoscopic supracervical hysterectomy and a derivative leiomyosarcoma

ABSTRACT: Unexpected malignant tumors are a rare finding after surgery for symptomatic leiomyomas but there is little doubt that morcellation of these lesions is associated with a higher risk of iatrogenic peritoneal spread compared to women having surgery without morcellation. Thus, the FDA has issued a warning against the use of power morcellation in the majority of women undergoing myomectomy or hysterectomy for treatment of fibroids.We pressent a case report of 50year old patient with intervertebral disc degeneration and multiple uterine fibroids decided to have laparoscopic supracervical hysterectomy. 28 months later the patient cystic adnexal massas removed by laparotomy and histologically, classified as leiomyosarcoma. 19 months after this latter surgery MRI revealed a 10 x 8 x 6 cm abdominal mass attached to the liver and numerous other nodules attached to the abdominal wall. We investigated genomic and expression profiles of four samples obtained from initial surgery and the malignant tumor that appeared 16 month later by molecular inversion probe (MIP) and transcriptome array hybridization. DNA was extracted from FFPE Tissue Samples using Covaris adaptive focused acoutics (AFATM) and truXTRACTM FFPE DNA kit and subjected to array analysis using the Affymetrix OncoScan and human Clariom D platforms according to the manufacturers protocol.

Project description:Sacrocolpopexy has been dubbed the “gold standard” repair for apical pelvic organ prolapse (POP). This study sought to determine a genetic cause for sacrocolpopexy failure by comparing genotypes from 10 women who suffered from early POP reoccurance after sacrocolpopexy surgery, versus 40 randomly selected women with long term success after the same procedure. We objectively defined early overt failure after robotic-assisted laparoscopic sacrocolpopexy as having a pelvic organ prolapse quantification system examination (POP-Q) of stage III or IV occurring in more than one compartment within six months after surgery. All medical records identified during this process were then reviewed by a panel of urogynecology attendings and fellows to select patients who were truly clinical outliers. By this method we identified 10 patients (cases) who experienced early overt surgical failure. We also randomly selected 40 controls from our research database which includes greater than 500 patients who underwent robotic-assisted laparoscopic sacrocolpopexy during the same time period and had been objectively and subjectively assessed for ≥ 12 months with surgical success at ≥ 12 months that did not undergo prolapse re-operation or re-treatment. Demographics and peri-operative details were compared between cases and controls. Exclusion criteria for controls included use of other graft material besides polypropylene mesh, prior surgery for prolapse involving graft material, and conversion to laparotomy. DNA from the 10 cases and 40 controls was isolated from buccal swabs and genotyped on a single nucleotide polymorphism (SNP) array that contains 250,000 markers (NspI 250K SNP array, Affymetrix, Santa Clara, CA). All women in this study identified as Caucasian. All subjects provided written informed consent to study participation and data release. This was a case-control study approved by the Institutional Review Board at the Atlantic Health System in Morristown New Jersey (R11-10-004).

This case-control study compared single genotypes of 10 cases to 40 controls. All subjects were identified as Caucasian. Cases were women who experienced early overt POP recurrence after robotic sacrocolpopexy, and controls were randomly selected women with long term success after the same procedure.
