BackgroundEndometrial cancer is the most common gynecologic cancer, and lymph node metastasis is one of the most important prognostic factors. Increasing evidence shows that sentinel lymph node (SLN) mapping is an effective alternative to comprehensive lymphadenectomy. Single photon emission CT with computed tomography (SPECT/CT) is associated with a high SLN detection rate.ObjectiveTo compare the clinical efficacy of SPECT/CT with that of lymphoscintigraphy in detecting SLNs in patients with endometrial cancer.MethodsBetween May 2014 and October 2018, 151 patients with endometrial cancer were enrolled in this study at the Department of Obstetrics and Gynecology of the Kagoshima University Hospital. Inclusion criteria were patients with endometrial cancer, older than 18 years, and with pre-operative International Federation of Gynecology and Obstetrics (FIGO) staging of I and II. All patients underwent pre-operative CT, and patients with suspected peritoneal dissemination and lymph node metastasis were excluded from this study. Pelvic SLNs were detected by injection of tecnetium-99m-labeled phytate into the uterine cervix. The number and locations of SLNs detected using lymphoscintigraphy and SPECT/CT were evaluated. JMP software (version 14, SAS Institute Inc., Cary, North Carolina, USA) was used for statistical analysis.ResultsA total of 151 patients who underwent pre-operative lymphoscintigraphy and SPECT/CT were included in the study. The median age was 57 years (range 24–79), and the median body mass index was 24.3 kg/m2 (range 16–40). The final pathology was as follows: 135 (89%) endometrioid carcinoma, 11 (7%) serous carcinoma, one (1%) clear cell carcinoma, and four (3%) other histotypes. Based on SPECT/CT, 204 pelvic SLNs were detected. The bilateral pelvic SLN detection rate was better for SPECT/CT (43% (65/151)) than for lymphoscintigraphy (32% (48/151)) (p<0.0001). The overall pelvic SLN detection rate (at least one pelvic SLN detected) was also better with SPECT/CT (77% (16/151)) vs lymphoscintigraphy (68% (102/151)) (p<0.0001). The distribution of SLN locations detected using SPECT/CT was as follows: external iliac, 91 (45%); obturator, 61 (30%); common iliac, 28 (14%); internal iliac, 19 (9%); para-aortic, 2 (1%); parametrium, 2 (1%), and presacral, 1 (1%). The SLN detection rate using SPECT/CT was significantly worse in patients of advanced age (p<0.0001).DiscussionOverall and bilateral SLN detection rate was better with SPECT/CT than with lymphoscintigraphy in patients with stage I/II endometrial cancer.

Abstract Background Sentinel lymph node biopsy (SLNB) is unnecessarily performed too often, owing to the high upstaging rates of ductal carcinoma in situ (DCIS). This study aimed to evaluate the upstaging rates of DCIS to invasive cancer, determine the prevalence of axillary lymph node metastasis, and identify the clinicopathological factors associated with upstaging and lymph node metastasis. We also examined surgical patterns among DCIS patients and determined whether SLNB guidelines were followed. Methods We retrospectively analysed 307 consecutive DCIS patients diagnosed by preoperative biopsy in a single centre between 2014 and 2018. Data from clinical records, including imaging studies, axillary and breast surgery types, and pathology results from preoperative and postoperative biopsies, were extracted. Univariate analyses using Chi-square tests and multiple logistic regression analyses were used to analyse the data. Results The rate of upstaging to invasive cancer was 19.2% (59/307). DCIS diagnosed by core-needle biopsy (odds ratio [OR]: 6.861, 95% confidence interval [CI]: 2.429–19.379), the presence of ultrasonic mass-forming lesions (OR: 2.782, 95% CI: 1.224–6.320), and progesterone receptor-negative status (OR: 3.156, 95% CI: 1.197–8.323) were found to be associated with upstaging. The rate of sentinel lymph node metastasis was only 1.9% (4/202), and all were total mastectomy patients diagnosed by core-needle biopsy. SLNB was performed in 37.2% of 145 breast-conserving surgery patients and 91.4% of 162 total mastectomy patients. Among the 202 patients who underwent SLNB, 145 (71.7%) without invasive cancer on final pathology had redundant SLNB. Two of 59 patients (3.4%) with disease upstaged to invasive cancer had inadequate primary staging of the axilla, as the rate seemed sufficiently small. Conclusions In patients with a preoperative diagnosis of DCIS, although an unavoidable possibility of upstaging to invasive cancer exists, axillary metastasis is unlikely. Only 2.7% of patients with DCIS undergoing total mastectomy were found to have sentinel lymph node metastases. SLNB should not be performed in breast-conserving surgery patients and should be reserved only for total mastectomy patients diagnosed by core-needle biopsy.

Abstract Objective The present study aimed to clarify the occurrence rate of lymphedema and prognosis in patients with endometrial cancer according to sentinel lymph node biopsy alone with intraoperative histopathological examination. Methods The study included 45 consecutive patients with endometrial cancer treated at Tohoku University Hospital between October 2014 and August 2017. All patients had endometrial carcinoma with endometrioid histology Grade 1 or Grade 2 confirmed by biopsy and stage I on magnetic resonance imaging and/or computed tomography at their preoperative evaluation. Sentinel lymph node detection was performed by radioisotope and dye. Patients who were diagnosed intraoperatively as negative for sentinel lymph node metastasis did not undergo further systematic pelvic lymphadenectomy. The occurrence rate of lymphedema and prognosis was evaluated. Results Bilateral sentinel lymph nodes were detected in 44 of 45 patients (97%). Forty-three patients underwent sentinel lymph node biopsy alone, and only two patients underwent systematic lymphadenectomy. Sentinel lymph node metastases were detected in one patient intraoperatively and two patients postoperatively as ITCs. No patients experienced recurrence. New symptomatic lower-extremity lymphedema was identified in one of 43 patients (2.3%) who underwent sentinel lymph node biopsy alone. Conclusion Sentinel lymph node biopsy alone with intraoperative histopathological diagnosis appears to be a safe and effective strategy to detect lymph node metastasis and to reduce the number of patients with lower-extremity lymphedema among patients with endometrial cancer.
