Risk factors in women 40 years of age and younger with endometrial carcinoma

Objective. To identify and compare risk factors among endometrial cancer patients ≤40 years of age, postmenopausal women with the same malignancy and women ≤40 years without malignancy. Design. Retrospective case–control study. Setting. Athens University, department of obstetrics and gynecology of a tertiary hospital serving a mainly urban population. Population. Endometrial cancer patients ≤40 years (study group, n = 40), postmenopausal women with the same malignancy (positive controls, n = 40) and women ≤40 (negative controls, n = 40) without endometrial cancer. Methods. Clinical history, treatment and follow‐up of patients were evaluated. Factors studied included age, histology, stage, grade, lymphovascular space involvement, body mass index (BMI), cytology, lymph node status, parity, smoking, family history, hypertension recurrence and survival. Main outcome measures. Differences in risk factors and characteristics. Results. Nulliparity, smoking and hypertension were significantly related with endometrial cancer in the study group compared to positive controls (p = 0.001, p < 0.01 and p < 0.001, respectively). BMI >30 significantly characterized patients in the study group compared to negative controls (p = 0.006). Finally, irregular menstruation and family history of cancer were observed more often in the study group compared to both control groups. Stage, grade, myometrial invasion, lymphovascular space involvement and lymph node status were comparable between the study and positive control groups. Conclusion. Nulliparity, obesity, unstable menstruation, smoking and cancer in the family are strongly correlated with endometrial cancer risk in women ≤40 years.

Safety of hormone replacement therapy in gynaecological cancer survivors

Therapy for endometrial, ovarian and cervical cancer in young women can cause sudden onset of intense menopausal symptoms, such as hot flushes, emotional disorders and sexual dysfunction. In order to overcome these unpleasant and sometimes severe symptoms, hormone replacement therapy (HRT) has proven to be very effective. However, its safety remains controversial. We reviewed English literature and examined whether administration of HRT in this specific population is related with more recurrences and worse prognosis. Current scientific data, comprising mainly retrospective studies, suggest that recurrence rates and survival are comparable between HRT users and non-users. However, large randomised trials are missing and definitive conclusions cannot be drawn. Gynaecological cancer survivors using HRT, although they seem to have little if any risk for recurrence, should be correctly informed about the lack of strong evidence.

Role of chromosome 3q26 gain in predicting progression of cervical dysplasia.

Objective This study aimed to determine whether 3q26 gain can predict which low-grade squamous intraepithelial lesions (LSILs) and atypical squamous cells of undetermined significance (ASCUSs) will progress to higher-grade squamous intraepithelial lesion (HSIL). Methods Liquid cytology specimens of LSIL and ASCUS from 73 women were examined using fluorescent in situ hybridization (FISH) for the detection of 3q26 gain. All women underwent colposcopy and biopsy at the initial visit and 40 of them with histology showing cervical intraepithelial neoplasia 1 (CIN 1) or human papillomavirus infection (koilocytosis) were included in the study. They were reevaluated with liquid cytology, colposcopy, and biopsy after a median follow-up of 17.5 months. Results A total of 40 cases were analyzed (31 LSILs and 9 ASCUSs). Of these cases, 8 (20%; 6 LSILs and 2 ASCUSs) were positive and 32 (80%) were negative for 3q26 gain according to FISH. Three of the 8 positive women (38%) progressed to HSIL/CIN 2 or worse, whereas none of the 32 negative women did so. 3q26 gain could predict progression with a negative predictive value of 100% (95% confidence interval, 89.1%–100%). In addition, women positive for 3q26 gain had a significantly lower regression rate compared with negative women (P = 0.009). Conclusions In this first prospective study, 3q26 gain in LSIL/ASCUS cytology exhibited an impressive negative predictive value for progression to HSIL/CIN 2 or worse. Thus, 3q26 gain may be useful in stratifying patients’ risk for progression and possibly alter management and reduce cost of follow-up.

Laparoscopic radical trachelectomy is an alternative to laparotomy with improved perioperative outcomes in patients with early-stage cervical cancer.

Objective Radical trachelectomy is an established surgical approach for managing young women with cervical cancer wishing to preserve fertility. The aim of this study was to compare perioperative outcomes between laparoscopic (LRT) and abdominal radical trachelectomy (ART). Methods We reviewed the records of all women undergoing either LRT or ART in our institution since 2004. Demographic data, clinicopathologic data, and perioperative outcomes were collected and compared between the 2 procedures. Results Overall, 27 women were identified. All of them had stage IB1 disease. Eleven (40.8%) women underwent LRT, whereas 16 (59.2%) women underwent ART. Age, parity, and body mass index, as well as histologic type, grade, and presence of lymphovascular space invasion were comparable between groups. The median length of the parametrial tissue removed was shorter in LRT versus ART (P = 0.022). The median blood loss and length of stay were significantly reduced in the LRT group (85 vs 800 mL, P < 0.001; and 4 versus 7 days, P = 0.003). The median operative time was longer with the laparoscopic approach (320 versus 192.5 minutes, P < 0.001). Early grade 1 to 2 postoperative morbidity (mainly high urinary residuals) was comparable between groups; however, more grade 3 and late morbidity events were recorded in the ART group. Conclusions This first comparison study between LRT and ART for fertility preservation in women with cervical cancer shows that laparoscopy performed better in terms of blood loss and length of stay. Laparoscopic radical trachelectomy could be the preferred option for these patients; however, further studies are needed to confirm comparable survival outcomes.

The role of intraoperative fluid optimization using the esophageal Doppler in advanced gynecological cancer: early postoperative recovery and fitness for discharge.

Objective To determine the effect of fluid optimization using esophageal Doppler monitoring (EDM) when compared to standard fluid management in women who undergo major gynecological cancer surgery and whether its use is associated with reduced postoperative morbidity. Methods From January 2009 to December 2010, women undergoing laparotomy for pelvic masses or uterine cancer had either fluid optimization using intraoperative EDM or standard fluid replacement without using EDM. Cases were selected from 2 surgeons to control for variability in surgical practice. Demographic and surgical details were collected prospectively. Univariate and multivariate analyses were performed to quantify the association between the use of EDM with “early postoperative recovery” and “early fitness for discharge.” Results A total of 198 women were operated by the 2 prespecified surgeons; 79 women had fluid optimization with EDM, whereas 119 women had standard anesthetic care. The use of ODM was associated with earlier postoperative recovery (adjusted odds ratio, 2.83; 95% confidence interval, 1.20–6.68; P = 0.02) and earlier fitness for discharge (adjusted odds ratio, 2.81; 95% confidence interval, 1.01–7.78; P = 0.05). Women with advanced-stage disease in the “EDM” group resumed oral diet earlier than women in the “no EDM” group (median, 1 day vs 2 days; P = 0.02). These benefits with EDM did not extend to women with early-stage disease/benign/borderline tumors. No significant difference in postoperative complications was noted. Conclusions Intraoperative fluid optimization with EDM in women with advanced gynecological cancer may be associated with improved postoperative recovery and early fitness for discharge. Studies with adequate power are needed to investigate its role in reducing postoperative complications.

Ultrasonographic markers and preoperative CA‐125 to distinguish between borderline ovarian tumors and stage I ovarian cancer

Preoperative evaluation of ovarian masses has become increasingly important for optimal planning of treatment. The aim of this study was to assess the role of preoperative serum cancer antigen 125 (CA‐125) levels in correlation with ultrasonographic features in order to distinguish between borderline ovarian tumors (BOTs) and stage I epithelial ovarian carcinoma (EOC).

Endometrial stromal sarcoma arising from endometriosis of the terminal ileum: The role of immunohistochemistry in the differential diagnosis

Low‐grade endometrial stromal sarcoma (LESS) is an uncommon uterine malignancy. Occasionally, it may develop in extrauterine endometriotic lesions and present morphological characteristics mimicking various neoplasms, making its diagnosis very challenging. We report a rare case of a 56‐year‐old woman presenting with a pelvic mass, initially presumed to be of ovarian origin. After surgical excision the diagnosis of a LESS arising from foci of endometriosis of the terminal ileum was established. Pelvic lymph nodes and omentum were also infiltrated. The patient received adjuvant chemotherapy and medroxyprogesterone; she is alive with no evidence of disease after a follow‐up of 38 months. Immunohistochemical characteristics of the tumor are very important for the differential diagnosis of this rare neoplasm and include diffuse strong positivity for CD 10, estrogen receptor expression and CD 34 negativity.

Survival after secondary cytoreduction for recurrent ovarian cancer: Which are the prognostic factors?

Significant controversy exists concerning the factors affecting survival after secondary cytoreduction (SCR) in recurrent ovarian cancer. This study aims to identify factors independently associated with survival after SCR.

Subserosal uterine injection of blue dye for the identification of the sentinel node in patients with endometrial cancer: a feasibility study

ObjectiveTo define the detection rate, sensitivity, and negative predictive value (NPV) of the sentinel node technique in patients with endometrial cancer.MethodsPatients with endometrial cancer after informed consent underwent subserosal injection of blue dye during hysterectomy in a tertiary gynae/oncology department between 2010 and 2014. The procedure was performed in all cases by the same team including two gynae/oncologist consultants and one trainee. All relevant perioperative clinicopathological characteristics of the population were recorded prospectively. The identified sentinel nodes were removed separately and a completion bilateral pelvic lymphadenectomy followed in all cases. Simple statistics were used to calculate the sensitivity and NPV of the method on per patient basis.ResultsFifty-four patients were included in this study. At least one sentinel node was mapped in 46 patients yielding a detection rate of 85.2%. Bilateral detection of sentinel nodes was accomplished in only 31 patients (57.4%). The mean number of sentinel nodes was 2.6 per patient and the commonest site of identification was the external iliac artery and vein area (66%). Six patients (11%) had a positive lymph node, and in five of them, this was the sentinel one yielding a sensitivity of 83.3% and an NPV of 97.5%. The overall detection rate improved significantly after the first 15 cases; however, this was not the case for the bilateral detection rate.ConclusionOur study is in accordance with previous studies of sentinel node in endometrial cancer and further demonstrates and enhances the confidence in the technique. In the current era of an ongoing debate on whether a systematic lymphadenectomy in patients with endometrial cancer is still necessary, we believe that the sentinel node is an acceptable alternative and should be applied routinely in tertiary centres following a strict algorithm.

Abdominal radical trachelectomy for treatment of deep infiltrating endometriosis of the cervix

Surgical management of deep infiltrating endometriosis can be very challenging even for experienced gynecologists. Radical procedures like bowel resection and nephrectomy have been reported for treatment of the disease. Our aim is to report abdominal radical trachelectomy for treatment of deep infiltrating endometriosis of the cervix causing obstructive uropathy and diminished kidney function. We present a 38‐year‐old woman who was treated in our department for cervical endometriosis involving the vagina and left parametrium. Abdominal radical trachelectomy, insertion of a pig‐tail catheter in the left ureter and end‐to‐end anastomosis of the uterus with the vagina was performed to remove the endometriotic lesion. Cooperation between gynecologists, urologists and nephrologists enabled fertility preservation as well as improvement of renal function. Deep infiltrating endometriosis is a complex disease that requires a multidisciplinary approach. Abdominal radical trachelectomy for cervical lesions seems feasible in this setting and helps preserve fertility.
