Evaluation of Quality of Life Outcomes in Women Undergoing Multimodality Treatment for Advanced Stage Endometrial Carcinoma

Background: Patients with FIGO stage III endometrial carcinoma often require multimodality adjuvant therapy to improve survival and recurrence rates; however, the optimal adjuvant therapy sequence is yet to be established. Several studies have tried to answer this question including RTOG 9708, PORTEC-3, and GOG 258. Collectively, these studies show that concurrent chemotherapy and radiation (chemoRT) with cisplatin followed by additional chemotherapy (CT) and CT alone are acceptable regimens. However, both strategies show that distant recurrence remains a problem when CT is delayed after RT, and local control is compromised without RT. A retrospective study from Washington University included women with advanced endometrial carcinoma who received carboplatin/paclitaxel concurrent with RT. Thirty-four patients experienced grade 3-4 toxicities. They found a median PFS of 42.8 months, median OS of 44.9 months, and 3-year OS of 80%. This study suggests that this regimen is safe with favorable response rates. Building off the above studies, we wish to prospectively assess outcomes of women with advanced endometrial carcinoma who receive concurrent chemoRT with a carboplatin/paclitaxel-based regimen. Methods: A total of 60 patients with FIGO stage III uterine carcinoma will be prospectively enrolled after undergoing surgical staging (currently accruing). CT will start approximately 4 weeks after surgery. Patients will receive 6 cycles of carboplatin (AUC 6) and paclitaxel (175 mg/m2). RT will be given during CT cycles 1-3. External beam RT will be given via intensity-modulated RT in once-daily fractions of 1.8-2.0 Gy for a total dose of 44-45 Gy to the pelvis (vaginal cuff, pelvic LN, and para-aortic lymph nodes). If there is grossly visible nodal disease seen at the time of treatment planning, a boost to 54 Gy will be given to those areas. If the patient has cervical stromal invasion, we will recommend that she receive a brachytherapy boost. Data will be collected on OS and PFS endpoints. Data will also be collected on provider- and patient-reported treatment toxicity. Patients will receive a series of questionnaires at baseline, 3, 6, 12, and 24 months after surgery. These are prospectively-validated questionnaires and include FACT-G, FACT-En, FACT/GOG-NTX, and FACT-C. For statistical analyses, continuous and categorical variables will be analyzed. Kaplan-Meier survival estimates will be calculated for local control and survival end points. For each patient, disease characteristics and adjuvant treatment will be placed in a simple logistic regression model for predicting survival endpoints. A multivariate analysis will be performed for exploratory purposes. Hazard ratios and 95% confidence intervals will be reported. Tests will be considered significant at p < 0.05.

A Prospective Study Comparing Three Injection Sites to Detect Sentinel Lymph Nodes in Endometrial Cancer

Uterine cancer is the most common gynecologic malignancy in developed countries. Adenocarcinoma of the endometrium is the most common histologic type of uterine cancer. Endometrial cancer is the fifth most frequent cancer in women in Switzerland. The incidence rose up to 5.9% in 2015. This tumor affects mainly older women, at 63 years on average. The majority of women are diagnosed at an early stage. Seventy-five to 90% of the patients are alerted by abnormal uterine bleeding very quickly, which allows a quick management of care and a high survival rate. Besides age, one of the main risk factor of developing an endometrial carcinoma is obesity. In fact, obese women have higher risk to have an endometrial cancer, but also at a younger age than the average and finally they have an increased risk of death due to this particular cancer. Although this cancer is linked to the co-morbidities that go with obesity like diabetes or hypertension. The treatment of endometrial cancer in most women is surgery involving a total hysterectomy and a bilateral salpingo-oophorectomy with or without a lymph node dissection. For patients with early stage endometrial cancer, there is a disagreement regarding lymph nodes dissection, because randomized controlled trials and a meta-analysis have shown no clear evidence on overall or recurrence-free survival and a higher incidence on early and late complications in relation with pelvic lymph node dissection. A systematic lymph node dissection consists of removing all the nodes within a nodal drainage basin. This dissection proves to be very difficult in obese patient and includes a risk to damage blood vessels or nerves. Moreover, lymph node dissection is associated with a higher morbidity, longer operating time, more frequent blood loss and finally symptomatic lymphedema and seroma. That is why, sentinel lymph node biopsy (SLNB) seems to be a good alternative to lymph node dissection. The tumor's spread is assessed in lymph nodes with a reduced morbidity. In fact, lymphadenectomy and its dangerous complications, like lymphedema, could be avoided in the vast majority of cases. Indeed, a histological analysis of these sentinel lymph-nodes (SLNs) leads to ultrastadification: cancers are graded depending on the presence and the size of metastasis in lymph nodes. Adjuvant treatments, such as radiotherapy or chemotherapy, can be suggested following these data and a better management of endometrial cancer is possible.
