RESUMO
Intravenous leiomyomatosis (IVL) is an uncommon variant of leiomyoma characterized by intravascular proliferation of a histologically benign smooth muscle tumor extending beyond the uterus into the distant great vessels. Leiomyomatosis may reach the inferior vena cava, right atrium, and pulmonary arteries. Owing to its rare occurrence, intracardiac leiomyomatosis has been reported as isolated case reports and small case series. Early diagnosis and prompt surgical intervention are vital to prevent cardiac symptoms, pulmonary embolism, and sudden death. Complete tumor resection is essential for a favorable outcome, usually assisted with multimodal surgical imaging and multidisciplinary surgical planning. Herein, we report the case of a 50-year-old female that presented with a three-month history of abdominal pain and lower extremity edema with evidence of IVL extending to the inferior vena cava and right atrium. The patient was managed with a single-stage surgery involving cardiopulmonary bypass and excision of the right atrial and inferior vena cava tumors, as well as modified radical total abdominal hysterectomy and bilateral salpingo-oophorectomy.
RESUMO
PURPOSE: Minimally invasive radical hysterectomy has been associated with increased recurrence of disease and worse survival compared with open radical hysterectomy for early-stage cervical cancer. We evaluated patterns of recurrence and histopathologic risk factors in patients who underwent robotic radical hysterectomy (RRH). METHODS: Patients who underwent RRH (4/2007-12/2018) were evaluated for specific locations of recurrent disease, disease-free survival, overall survival (OS), and histopathologic risk factors for recurrence. Inclusion criteria were follow-up ≥ 1 year, histology with adenocarcinoma, adenosquamous, or squamous carcinoma and clinical stage IA2 to IB ≤ 4-cm tumor size cervical cancers (FIGO-2018). RESULTS: A total of 140 patients underwent RRH and 112 met criteria. Median tumor size was 2.1 cm [interquartile range (IQR): 1.1-3.3]. Median follow-up was 61 months (IQR: 36-102). Fifty (45%) patients underwent adjuvant radiation ± cisplatin with either Sedlis' or Peters' risk factors. There were 11 (9.8%) recurrences with median disease-free survival of 12 (IQR 8.5) months. All patients with recurrence had measured tumor size ≥ 2 cm (median tumor size 3-cm (IQR: 2.6-4.0). Tumor size > 2 cm was associated with Sedlis' intermediate-risk factors (p < 0.05) and Peters' high-risk factors (p < 0.05). Forty patients underwent preoperative conization, and two (5%) with deep positive margins in lesions > 2 cm recurred. Five (4.5%) of patients had carcinomatosis representing 45% of all recurrences. Carcinomatosis was associated with reduced OS compared with other recurrence patterns (22 months vs. 7.8 years, p < 0.05). CONCLUSIONS: Carcinomatosis was observed in early-stage cervical cancers treated with RRH and was associated with reduced OS. All recurrences were associated with lesions ≥ 2 cm, and no recurrences were identified with negative conization margins.

PURPOSE: To establish the bilateral pelvic concordance rate of the sentinel lymph node (SLN) and determine the likelihood of lymph node metastasis in cases of mapping failure. METHODS: A database analysis was performed on 414 patients with clinical stage I endometrial cancer who underwent SLN mapping followed by robotic hysterectomy and completion pelvic (n=414, 100%) and aortic (n=186, 44.9%) lymphadenectomy from March 2011 to August 2016. Stage, histology, SLN sites, and surgico-pathologic findings were analyzed. The bilateral concordance rate of SLN location, successful unilateral and bilateral mapping rates, false negative rate, and non-SLN metastasis associated with mapping failure were calculated. RESULTS: Histologies included 354 (85.5%) endometrioid, 39 (9.4%) serous, 16 (3.9%) carcinosarcoma, 4 (1.0%) clear cell, and 1 (0.2%) undifferentiated. Final stages included 262 (63.3%) IA, 36 (8.7%) IB, 15 (3.6%) II, 6 (1.4%) IIIA, 68 (16.4%) IIIC1, and 27 (6.5%) IIIC2. Bilateral SLN mapping was successful in 355 (85.7%) patients, and 266 (74.9%) demonstrated mapping to the symmetrical lymphatic group contralaterally. The mapping failure rate was 13.5% (56/414) unilaterally and 0.7% (3/414) bilaterally. SLN locations were external iliac (69.1%), obturator (25.1%), internal iliac (2.2%), common iliac (1.9%), pre-sacral (0.9%), aortic (0.4%), parametrial (0.3%), and para-rectal (0.1%). Lymph node metastases were identified in 95 (22.9%) pelvic and 27 (6.5%) aortic nodes. 10 (16.9%) cases with mapping failure had lymph node metastasis on completion lymphadenectomy, similar to the proportion of SLNs with metastases (p=0.35). However, macro-metastases were more common in mapping failure completion lymphadenectomies than in the positive SLNs (80% vs 22.3%, p<0.001). CONCLUSION: The contralateral SLN location concordance rate was 75%. Most SLNs were along the medial external iliac or obturator locations. The rate of positive lymph nodes associated with SLN mapping failure was 16.9%, similar to the overall node-positive rate. The detection of pelvic node metastasis with SLN mapping failure was largely populated with macro-metastases and confirms the necessity of completion lymphadenectomy with mapping failure.
