Recently, there has been an intense discussion about the issue of fibroid and uterine morcellation in relation to the risk of unrecognized uterine sarcoma spread. Morcellation can negatively influence the prognosis of patients, and transecting the specimen into pieces prevents the pathologist from performing proper disease staging. Many societies have published their statements regarding this issue. The European Society for Gynecological Oncology has established a working group of clinicians involved in diagnostics and treatment of oncogynecological patients to provide a statement from the oncological point of view. Leiomyosarcomas and undifferentiated endometrial sarcomas have generally dismal prognosis, whereas low-grade endometrial stromal sarcomas and adenosarcomas have variable prognosis based on their stage. A focus on the detection of patients at risk of having a sarcoma should be mandatory before every surgery where morcellation is planned by evaluation of risk factors (African American descent, previous pelvic irradiation, use of tamoxifen, rapid lesion growth particularly in postmenopausal patients) and exclusion of patients with any suspicious ultrasonographic signs. Preoperative endometrial biopsy should be mandatory, although the sensitivity to detect sarcomas is low. An indication for myomectomy should be used only in patients with pregnancy plans; otherwise en bloc hysterectomy is preferred in both symptomatic and postmenopausal patients. Eliminating the technique of morcellation could lead to an increased morbidity in low-risk patients; therefore, after thorough preoperative evaluation and discussion with patients, morcellation still has its place in the armamentarium of gynecologic surgery.

The diagnosis of a uterine smooth muscle lesion is, in the majority of cases, straightforward. However, in a small number of cases, the morphological criteria used in such lesions cannot differentiate with certainty a benign from a malignant lesion and a diagnosis of smooth muscle tumor with uncertain malignant potential (STUMP) is made. Uterine leiomyosarcomas are often easy to diagnose but it is difficult or even impossible to identify a prognostic factor at the moment of the diagnosis with the exception of the stage. We hypothesize, for uterine smooth muscle lesions, that there is a gradient of genomic complexity that correlates to outcome. We first tested this hypothesis on STUMP lesions in a previous study and demonstrated that this 'gray category' could be split according to genomic index into two groups. A benign group, with a low to moderate alteration rate without recurrence and a malignant group, with a highly rearranged profile akin to uterine leiomyosarcomas. Here, we analyzed a large series of 77 uterine smooth muscle lesions (from 76 patients) morphologically classified as 19 leiomyomas, 14 STUMP and 44 leiomyosarcomas with clinicopathological and genomic correlations. We confirmed that genomic index with a cut-off=10 is a predictor of recurrence (P<0.0001) and with a cut-off=35 is a marker for poor overall survival (P=0.035). For the tumors confined to the uterus, stage as a prognostic factor was not useful in survival prediction. At stage I, among the tumors reclassified as molecular leiomyosarcomas (ie, genomic index ≥10), the poor prognostic markers were: 5p gain (overall survival P=0.0008), genomic index at cut-off=35 (overall survival P=0.0193), 13p loss including RB1 (overall survival P=0.0096) and 17p gain including MYOCD gain (overall survival P=0.0425). Based on these findings (and the feasibility of genomic profiling by array-comparative genomic hybridization), genomic index, 5p and 17p gains prognostic value could be evaluated in future prospective chemotherapy trials.

The diagnosis and management of uterine smooth muscle tumors with uncertain malignant potential (STUMP) is often challenging, and genomic data on these lesions as well as on uterine smooth muscle lesions are limited. We tested the hypothesis that genomic profile determination by array-CGH could split STUMP into a benign group with scarce chromosomal alterations akin to leiomyoma and a malignant group with high chromosomal instability akin to leiomyosarcoma. Array-CGH genomic profile analysis was conducted for a series of 29 cases of uterine STUMP. A group of ten uterine leiomyomas and ten uterine leiomyosarcomas served as controls. The mean age was 50 years (range, 24-85) and the follow-up ranged from 12 to 156 months (average 70 months). Since STUMP is a heterogenous group of tumors with genomic profiles that can harbor few to many chromosomal alterations, we compared genomic indices in leiomyomas and leiomyosarcomas and set a genomic index=10 threshold. Tumors with a genomic index <10 were classified as nonrecurring STUMPs and those with a genomic index >10 represented STUMPs with recurrences and unfavorable outcomes. Hence, the genomic index threshold splits the STUMP category into two groups of tumors with different outcomes: a group comparable to leiomyomas and another similar to leiomyosarcomas, but more indolent. In our STUMP series, genomic analysis by array-CGH is an innovative diagnostic tool for problematic smooth muscle uterine lesions, complementary to the morphological evaluation approach. We provide an improved classification method for distinguishing truly malignant tumors from benign lesions within the category of STUMP, especially those with equivocal morphological features.

An international joint statement about the use of hyperthermic intraperitoneal chemotherapy (HIPEC) in ovarian cancer was published in 2016, warning about the uncritical use of HIPEC outside controlled studies. This statement has now been updated after the most recent literature was reviewed by the participating study groups and societies. HIPEC became a treatment option in patients with advanced colon cancer after positive results of a randomized trial comparing surgery and HIPEC versus palliative treatment alone. Although this trial did not compare the added value of HIPEC to surgery alone, HIPEC for the treatment of peritoneal metastases was in the subsequent years generalized to many other cancer types associated with peritoneal carcinomatosis including epithelial ovarian cancer (EOC). In the meantime, new evidence from prospective randomized trials specifically for EOC-patients emerged, with however contradicting results and several quality aspects that made the interpretation of their findings critical. Moreover, three additional trials in colorectal cancer failed to confirm the previously presumed survival benefit through the implementation of HIPEC in peritoneally disseminated colorectal cancers. Based on a still unclear and inconsistent landscape, the authors conclude that HIPEC should remain within the remit of clinical trials for EOC-patients. Available evidence is not yet sufficient to justify its broad endorsement into the routine clinical practice.
