Abstract Introduction: There are controversies over the treatment options for pelvic lymph node metastasis in low rectal cancer. The role of neoadjuvant radiotherapy in radical treatment of pelvic lymph node metastasis is still unidentified. Total mesorectal excision (TME) with Laparoscopic pelvic lymph node dissection (LPLND) provides lower pelvic recurrence in 5 years than TME only. Material and Methods: Prospective, uncontrolled clinical trial for patients with low rectal cancer (below peritoneal fold), who had suspected lateral pelvic lymph node metastasis on MRI scan and the patients did not have contraindication for laparoscopic surgery. Result: From January 2017 to February 2018 we performed 12 cases of LPLND. There was no con-version to open surgery. The average time for lymphadenectomy is 75 minutes with an average amount of blood loss of 97ml. Only 1 case had postoperative urinary retention (8%). The rate of pos-itive pelvic node was 5.8%, with an average of resected nodes of 4.9 nodes. Lymph nodes size on MRI scan in the positive pelvic node group was 20.6mm, compared to 7mm in the negative group. Conclusion: Laparoscopic lateral pelvic lymph node dissection is a feasible and safe technique and should be done by experienced colorectal surgeons. Aging, female sex and pelvic lymph node size on MRI are related to pelvic lymph node metastasis.

Background: The aim of this study is to determine the necessary extent of penile lymph node dissection (PLND) in penile cancer patients with inguinal lymph node extracapsular extension (ILN-ENE).Methods: Penile cancer patients who underwent PLND in 15 centers from January 2006 to April 2020 were retrospectively analyzed. PLND was performed in patients with ILN-ENE.Results: Sixty-two patients with ILN-ENE were included in the analysis. A total of 51.6% (32/62) of the patients were confirmed to have pelvic lymph node metastasis (PLNM), and 31.3% (10/32) of patients were confirmed to have multiple PLNMs. Of the patients with metastases, 59.4% (19/32) had bilateral inguinal lymph node metastasis (ILNM). According to the anatomical structure, 71.9% (23/32) of the patients had PLNM in the external iliac region, and 56.2% (18/32) had PLNM in the obturator region. Among those with oligo-PLNM, 65.1% (28/43) of the patients had PLNM in the external iliac region and 38.9% (15/43) had PLNM in the obturator region. A significant overall survival difference was observed between patients with the bilateral ILNM and unilateral ILNM (36-month: 21.2 vs. 53.7%, respectively, P = 0.023). Patients with bilateral ILNM had relatively poor metastasis-free survival compared with unilateral ILNM (36-month: 33.0 vs. 13.9%, respectively, P = 0.051).Conclusions: The external iliac and obturator region were the most commonly affected regions in patients with ILN-ENE, and these regions were the only affected regions in patients with oligo-PLNM. Patients with bilateral ILNM had a high risk of PLNM and worse survival.

We aim to review the literature for studies investigating the oncological outcomes of patients with penile cancer (PC) undergoing bilateral pelvic lymph node dissection (PLND) in the presence of inguinal lymph node metastasis (LNM) who are at risk of harboring pelvic metastasis. A search of English language literature was performed using the PubMed-MEDLINE database up to 3 December 2020 to identify articles addressing bilateral PLND in PC patients. Eight articles investigating bilateral PLND met our inclusion criteria. Patients with pelvic LNM have a dismal prognosis and, therefore, PLND has an important role in both the staging and treatment of PC patients. Ipsilateral PLND is recommended in the presence of ≥2 positive inguinal nodes and/or extranodal extension (ENE). Significant survival improvements were observed with a higher pelvic lymph node yield, in patients with pN2 disease, and in men treated with bilateral PLND as opposed to ipsilateral PLND. Nevertheless, the role of bilateral PLND for unilateral inguinal LNM remains unclear. Although the EAU guidelines state that pelvic nodal disease does not occur without ipsilateral inguinal LNM, metastatic spread from one inguinal side to the contralateral pelvic side has been reported in a number of studies. Further studies are needed to clarify the disseminative pattern of LNM, in order to establish PLND templates according to patients’ risk profiles and to investigate the benefit of performing bilateral PLND for unilateral inguinal disease.

386 Background: Inguinal lymph node dissection (ILND) for lymph node metastasis (LNM) of squamous cell carcinoma of the penis (SCCP) can be a curative surgical treatment. Having the potential to identify clinical and pathological factors that predict LNM is important because of the poor prognosis this diagnosis carries. Methods: A retrospective review of 51 patients that underwent inguinal plus pelvic lymph node dissection from 1999 to 2012 was preformed. Age, race, body mass index (BMI), significant lymphadenopathy on preoperative imaging (nodes > 1 cm), palpable lymphadenopathy, and pathologic depth of invasion and diameter of the primary penile tumor along with associated lymphovascular invasion (LVI) were recorded and analyzed as potential predictors of LNM. Results: Median patient age was 65 and the median BMI was 29.3. Thirty-nine patients (76.5%) were white, 3 (5.9%) African American, and 9 (17.6%) were Hispanic. Median primary penile tumor diameter was 3.2 cm with 7, 29, and 15 patients having well, moderate, and poorly differentiated tumors. Pre-operatively, 32 patients (62.7%) had palpable lymphadenopathy on physical exam and 26 (51.0%) had significant lymphadenopathy on imaging (93% CT, 7% MRI), with 24 (47.1%) having both findings. Thirty-one patients (60.8%) who underwent ILND had pathological LNM. On univariate analysis, palpable nodes (p < 0.001), nodes on imaging (p <0.001), having both palpable nodes and nodes on imaging (p < 0.001), age (p = 0.02), and LVI (p = 0.04), were significantly associated with LMN. On multivariate analysis, having nodes on imaging (p = 0.001) and age < 65 years (p = 0.049) were significant for predicting LNM. Conclusions: In evaluation of patients with T1-T3 penile cancer, multiple factors were predictive of LNM in our series: palpable and radiographic nodes, younger than age 65 and LVI. Inguinal adenopathy defined as more than 1 cm appears to better predict occult nodal metastasis, however, this must be weighed in terms of the additional cost and clinical yield provided by widespread adoption of pelvic (CT or MRI) imaging in all patients with aggressive primary penile tumor phenotypes.

Pelvic Lymph Node Metastasis

The seminal Gynecologic Oncology Group study on surgical pathologic spread patterns of endometrial cancer demonstrated the risk of pelvic lymph node metastasis for clinical stage I endometrial cancer based on tumor grade and thirds of myometrial invasion. However, the FIGO staging system assigns surgical stage by categorizing depth of myometrial invasion in halves. The objective of this study was to determine the incidence of pelvic lymph node metastasis in endometrial cancer based on tumor grade and myometrial invasion as per the current FIGO staging system. We reviewed the records of all patients who underwent primary surgical staging for clinical stage I endometrial cancer at our institution between May 1993 and November 2005. To make the study cohort as homogeneous as possible, we included only cases of endometrioid histology. We also included only patients who had adequate staging, which was defined as a total hysterectomy with removal of at least eight pelvic lymph nodes. During the study period, 1036 patients underwent primary surgery for endometrial cancer. The study cohort was composed of the 349 patients who met study inclusion criteria. Distribution of tumor grade was as follows: grade 1, 80 (23%); grade 2, 182 (52%); and grade 3, 87 (25%). Overall, 30 patients (9%) had pelvic lymph node metastasis. The incidence of pelvic lymph node metastasis in relation to tumor grade and depth of myometrial invasion (none, inner half, and outer half) was as follows: grade 1–0%, 0%, and 0%, respectively; grade 2–4%, 10%, and 17%, respectively; and grade 3–0%, 7%, and 28%, respectively. We determined the incidence of pelvic nodal metastasis in a large cohort of endometrial cancer patients of uniform histologic subtype in relation to tumor grade and a one-half myometrial invasion cutoff. These data are more applicable to current surgical practice than the previously described one-third myometrial invasion cutoff results.
