Node Distribution

Objectives. To provide a better understanding of the distribution of inguinal nodes in order to prevent the complications of unnecessary and extended dissections in penile cancer.Methods. The bilateral inguinal regions of 19 male cadavers were dissected. Nodal distribution was noted and quantified based on anatomical location. The superficial nodes were subdivided into quarters as follows: superomedial, superolateral, inferomedial, and inferolateral. Statistical analysis was performed comparing node distribution between quarters using one-way analysis of variance (ANOVA), and the unpairedT-test was used between superficial and deep nodes.Results. Superficial nodes were found in all inguinal regions studied (mean = 13.60), and their distribution was more prominent in the superomedial quarter (mean = 3.94) and less in the inferolateral quarter (mean = 2.73). There was statistical significance between quarters when comparing the upper group with the lower one (P=0.02). Nodes were widely distributed in the superficial region compared with deep lymph nodes (mean = 13.60 versus 1.71,P<0.001).Conclusions. A great number of inguinal lymph nodes are distributed near the classical anatomical landmarks for inguinal lymphadenectomy, more prominent in upper quadrants.

Operative Complications

Our aim is to review the benefits as well as techniques, surgical outcomes, and complications of minimally invasive inguinal lymph node dissection (ILND) for penile cancer. The PubMed, Wiley Online Library, and Science Direct databases were reviewed in March 2020 for relevant studies limited to those published in English and within 2000–2020. Thirty-one articles describing minimally invasive ILND were identified for review. ILND has an important role in both staging and treatment of penile cancer. Minimally invasive technologies have been utilized to perform ILND in penile cancer patients with non-palpable inguinal lymph nodes and intermediate to high-risk primary tumors or patients with unilateral palpable non-fixed inguinal lymph nodes measuring less than 4 cm, including videoscopic endoscopic inguinal lymphadenectomy (VEIL) and robotic videoscopic endoscopic inguinal lymphadenectomy (RVEIL). Current data suggest that VEIL and RVEIL are feasible and safe with minimal intra-operative complications. Perhaps the strongest appeal for the use of minimally-invasive approaches is their faster post-operative recovery and less post-operative complications. As a result, patients can tolerate this procedure better and surgeons can offer surgery to patients who otherwise would not be a candidate or personally willing to undergo surgery. When compared to open technique, VEIL and RVEIL have similar dissected nodal count, a surrogate metric for oncological adequacy, and a none-inferior inguinal recurrence rate. Larger randomized studies are encouraged to investigate long-term outcome and survival rates using these minimally-invasive techniques for ILND.

Summary Aim: Multiple procedures for the quantification of activity leakage in radiation synovectomy of the knee joint have been described in the literature. We compared these procedures considering the real conditions of dispersion and absorption using a corpse phantom. Methods: We simulated different distributions of the activity in the knee joint and a different extra-articular spread into the inguinal lymph nodes. The activity was measured with a gammacamera. Activity leakage was calculated by measuring the retention in the knee joint only using an anterior view, using the geometric mean of anterior and posterior views, or using the sum of anterior and posterior views. The same procedures were used to quantify the activity leakage by measuring the activity spread into the inguinal lymph nodes. In addition, the influence of scattered rays was evaluated. Results: For several procedures we found an excellent association with the real activity leakage, shown by an r² between 0.97 and 0.98. When the real value of the leakage is needed, e. g. in dosimetric studies, simultaneously measuring of knee activity and activity in the inguinal lymph nodes in anterior and posterior views and calculation of the geometric mean with exclusion of the scatter rays was found to be the procedure of choice. Conclusion: When measuring of activity leakage is used for dosimetric calculations, the above-described procedure should be used. When the real value of the leakage is not necessary, e. g. for comparing different therapeutic modalities, several of the procedures can be considered as being equivalent.
