A Case of Endometrial Carcinoma Removed Laparoscopically–What Should be done?

Please be sure an see the Addendum below which deals with the totally different case of a leimyosarcoma removed by morcellation (meaning in pieces laparoscopically)

(Addendum, 9-9-2014: Since I wrote this post, I have become aware of an article that is worth reviewing: Sentinel node mapping in high risk endometrial cancer after laparoscopic supracervical hysterectomy with morcellation, International Journal of Surgery Case Reports, Volume 4, Issue 10, Pages 809–812, 2013. [Full Text HTML] [PubMed Abstract,Citations, and Related Articles])

A postmenopausal patient with uterine fibroids and post menopausal bleeding (previously negative endometrial biopsy, previous pelvic ultrasound and clinical exam showed 16 week uterus). 

Patient underwent bilateral salpingo-ophorectomy and supracervical hysterectomy (meaning the cervix was left behind). The uterus was removed by morcellation (meaning in pieces by laparoscopic surgery).

Uterine pathology indicated a FIGO histologic grade 2. “Accurate diagnosis of the depth of invasion is limited due to the fact that this is a morcellated specimen. In examined sections the adenocarcinoma does not appear to invade more than half of the myometrium and will provisionally be staged as IA based on available findings (again accurate depth of invasion is difficult to accurately ascertain in a morcellated specimen, and the cervix is also not available for examination).”

The questions to discuss with your oncologist (that is, these questions are in addition to the usual questions for endometrial carcinoma that are detailed in the post When the Diagnosis is Endometrial Cancer–Questions to Ask the Doctor):

1. Does morcellation (removal of the uterus in small pieces [necessary for laparoscopic removal]) allow for adequate staging of uterine endometrial carcinoma?

2. What additional evaluation (if any) is indicated because the endometrial carcinama was removed in pieces (morcellation).

3. Does morcellation of endometrial carcinoma make spread of disease more likely than an abdominal hysterectomy would?

4. Does morcellation of endometrial carcinoma change the survival statistics versus an abdominal hysterectomy?

5. What additional evaluation and treatment (if any) are indicated?

 The following studies address these issues:
