INTRODUCTION
Historically, therapeutic avenues for patients with clinical stage II seminoma germ cell tumors (SGCT) were confined to radiotherapy and chemotherapy. While survival rates with these modalities are commendable, both entail substantial long-term morbidities. Furthermore, this youthful patient cohort exhibits elevated rates of secondary malignancies, surfacing decades post-successful primary cancer treatment (1). Recently, retroperitoneal lymph node dissection (RPLND) has emerged as a primary treatment consideration for individuals with low-volume metastatic seminoma (2-4). However, there is a dearth of video documentation illustrating the robotic assisted (RA) bilateral approach (5- 7).
METHODS
We present the case of a 24-year-old male who underwent prior left orchiectomy for seminoma (pT1b). Despite negative serum tumor markers, a 1.7 x 1.4cm lymph node enlargement was identified in the aortic bifurcation after 4 months, classifying the patient as stage IIA per the IGCCCG risk classification. Subsequently, a RA bilateral template RPLND was performed due to the patient's refusal of chemotherapy, citing concerns about offspring.
RESULTS
The surgery was performed, incorporating nerve sparing techniques, lasting 4h13minutes, an estimated bleeding rate of 400ml, without intraoperative complications. The patient was discharged within 24 hours of the procedure, following a prescribed low-fat diet.
CONCLUSION
The patient experienced postoperative well-being, painlessness, and resumed work three weeks post-procedure. Preserved ejaculation was noted, and adjuvant therapy was performed with 2 cycles of EP due to the anatomopathological result. The feasibility of robotic primary RPLND for SGCT was demonstrated, showing reduced postoperative pain and early hospital discharge. Further studies are necessary to validate our findings regarding oncological, safety, and functional outcomes.

BACKGROUND
Retroperitoneal sarcomas (RPS) are rare tumours of mesenchymal origin, commonly presented as a large tumour mass at time of diagnosis. We investigated the impact of body composition on outcome in patients operated on for primary localized RPS.
PATIENTS AND METHODS
We retrospectively analysed data for all patients operated on for primary RPS at our institution between 1999 and 2020. Preoperative skeletal muscle area (SMA), visceral and subcutaneous adipose tissue area (VAT and SAT) and muscle radiation attenuation (MRA) were calculated using computed tomography scans at the level of third lumbar vertebra. European Working Group on Sarcopenia in Older People (EWGSOP2) criteria were applied to define myopenia. Using maximum log-rank statistic method we determined the optimal cut-off values of body composition parameters. Myosteatosis was defined based on determined MRA cut-offs.
RESULTS
In total 58 patient were eligible for the study. With a median follow-up of 116 months, the estimated 5-year overall survival (OS) and local-recurrence free survival (LRFS) were 66.8% and 77.6%, respectively. Patients with myopenia had significantly lower 5-year OS compared to non-myopenic (p = 0.009). Skeletal muscle index and subcutaneous adipose tissue index predicted LRFS on univariate analysis (p = 0.052 and p = 0.039, respectively). In multivariate analysis high visceral-to-subcutaneous adipose tissue area ratio (VSR) independently predicted higher postoperative complication rate (89.2% . 10.8%, p = 0.008). Myosteatosis was associated with higher postoperative morbidity.
CONCLUSIONS
Myopenia affected survival, but not postoperative outcome in RPS. Visceral obesity, VSR (> 0.26) and myosteatosis were associated with higher postoperative morbidity. VSR was better prognostic factor than VAT in RPS.

A 57-year-old male had abdominal pain and distension for 6-7 months with a palpable swelling in the right lumbar region. Contrast-enhanced computed tomography abdomen showed a large heterogeneous lesion with fat density measuring 22 cm ´ 16.5 cm in the right suprarenal region. Laparotomy was done which showed an encapsulated mass measuring 21 cm ´ 14 cm ´ 5 cm. Cut section revealed yellowish areas admixed with hemorrhage and large areas of necrosis. Microscopy revealed adrenal myelolipoma. The patient was found to have sickling positive. High-performance liquid chromatography showed double heterozygous for HbS and beta-thalassemia trait. The association of giant adrenal myelolipoma with double heterozygous for HbS and beta-thalassemia trait is rare, and as clinically it simulates retroperitoneal sarcoma, awareness of this rare entity is critical for its accurate diagnosis and proper management.

BACKGROUND
A survey of medical oncologists (MOs), radiation oncologists (ROs), and surgical oncologists (SOs) who are experts in the management of patients with metastatic colorectal cancer (mCRC) was conducted to identify factors used to consider metastasis-directed therapy (MDT).
MATERIALS AND METHODS
An online survey to assess clinical factors when weighing MDT in patients with mCRC was developed based on systematic review of the literature and integrated with clinical vignettes. Supporting evidence from the systematic review was included to aid in answering questions.
RESULTS
Among 75 experts on mCRC invited, 47 (response rate 62.7%) chose to participate including 16 MOs, 16 ROs, and 15 SOs. Most experts would not consider MDT in patients with 3 lesions in both the liver and lung regardless of distribution or timing of metastatic disease diagnosis (6 vs. 36 months after definitive treatment). Similarly, for patients with retroperitoneal lymph node and lung and liver involvement, most experts would not offer MDT regardless of timing of metastatic disease diagnosis. In general, SOs were willing to consider MDT in patients with more advanced disease, ROs were more willing to offer treatment regardless of metastatic site location, and MOs were the least likely to consider MDT.
CONCLUSIONS
Among experts caring for patients with mCRC, significant variation was noted among MOs, ROs, and SOs in the distribution and volume of metastatic disease for which MDT would be considered. This variability highlights differing opinions on management of these patients and underscores the need for well-designed prospective randomized trials to characterize the risks and potential benefits of MDT.

Meta-Analysis Review
To evaluate the oncological outcomes and safety of primary retroperitoneal lymph node dissection (RPLND) in patients with clinical stage (CS) II seminomatous testicular germ cell tumor (TGCT). A literature search using PubMed, Scopus, and Cochrane Library was conducted on July 2023 to identify relevant studies according to the Preferred Reporting Items for Systematic Review and Meta Analysis (PRISMA) guidelines. The pooled recurrence rate and treatment-related complications were calculated using a random effects model. Overall 8 studies published between 1997 and 2023 including a total of 355 patients were selected for systematic review and meta-analysis with the overall median follow-up of 38 months. The overall and infield recurrence rate were 0.14 (95% CI: 0.08-0.22) and 0.04 (95% CI: 0.00-0.11), respectively. The overall pooled rate of ≥ Clavien Dindo grade III complications was 0.04 (95% CI: 0.01-0.10); there was no significant heterogeneity (I^2 = 35.10%, P = 0.19). Antegrade ejaculation was preserved with the overall pooled rate of 0.98 (95% CI: 0.95-1.00); there was no significant heterogeneity on Chi-square and I2 tests (I^2 = 0.00%, P = 0.58). Primary RPLND is a safe and effective treatment option for patients with CS II seminomatous TGCT resulting highly promising cure rates combined with low treatment-associated adverse events, at medium-term follow-up. However, owing to the lack of comparative studies to the current standard of care and the limited follow-up, individual decision must be made with the informed patient in a shared decision process together with a multidisciplinary team.

INTRODUCTION
Almost 20 % of patients with Non-Seminomatous Germinative Cell Tumors (NSGCT) will require intrathoracic metastasectomy after chemotherapy. The authors aim to determine their long-term survival rates.
METHODS
Retrospective study including patients with NSGCT and intrathoracic metastasis after systemic therapy from January 2011 to June 2022. Treatment outcomes and overall survival were analyzed with the Kaplan-Meier method.
RESULTS
Thirty-seven male patients were included with a median age of 31.8 years. Six presented with synchronous mediastinum and lung metastasis, nine had only lung, and 22 had mediastinal metastasis. Over half had retroperitoneal lymph node metastasis. Twenty-two had dissimilar pathologies, with a discordance rate of 62 %. Teratoma and embryonal carcinoma were the prevalent primary tumor types, 40.5 % each, while teratoma was predominant (70.3 %) in the metastasis group. Thoracotomy was the main surgical approach (39.2 %) followed by VATS (37.2 %), cervico-sternotomy (9.8 %), sternotomy (5.8 %), and clamshell (3.9 %). Lung resection was performed in 40.5 % of cases. Overall, 10-year survival rates were 94.3 % with no surgical-related mortality.
CONCLUSION
Multimodality treatment with systemic therapy followed by radical surgery offers a high cure rate to patients with intrathoracic metastatic testicular germ cell tumors.

INTRODUCTION
Radical surgical resection with negative margins is the mainstay of treatment for retroperitoneal vascular leiomyosarcomas. Given the retroperitoneal location of these tumors, open surgery is, historically, the chosen surgical approach, however, it is burdened with high postoperative morbidity. In selected cases, the small dimension of the tumor and a favorable location, allow to perform a minimally invasive treatment.
PRESENTATION OF CASE
A 67-year-old female patient with a diagnosis of a leiomyosarcoma arising from the left renal vein underwent a robotic resection of the left renal vein with preservation of the left kidney and a relative outflow trough the gonadal vessels. The patient was discharged on the fourth postoperative day without any complications and there was no tumor recurrence noted during the 24-month follow-up period.
DISCUSSION
Vascular retroperitoneal leiomyosarcomas are very rare tumors requiring a complete en bloc gross tumor resection in order to achieving microscopically negative margins on the vein of origin. Thanks to the preoperative histological diagnosis and radiological study of the neoplasm, it was possible to proceed to a highly personalized and minimally invasive treatment with respect of oncological criteria.
CONCLUSION
In selected cases, a minimally invasive surgery of vascular leiomyosarcoma could be a feasible and safe treatment option.

Robotic nephron-sparing surgery is traditionally performed via a transperitoneal (TP) approach. However, the retroperitoneal (RP) approach has gained popularity, particularly for posterolateral renal masses. The RP approach is associated with shorter operative time, less blood loss, and shorter length of stay, while preserving oncologic outcomes in selected masses. Here, we aim to assess the feasibility of the RP approach in excising anterior renal masses. Patients ≥ 18 years of age who underwent robotic nephron-sparing surgery for anterior renal masses were retrospectively identified (2008-2022). Baseline demographics, tumor characteristics, and perioperative data were collected and characterized based on TP vs RP approaches. Wilcoxon rank sum test and Pearson's Chi-squared test were used to compare continuous and categorical variables, respectively. Two hundred and sixteen patients were included-178 (82.4%) underwent TP approach and 38 (17.6%) underwent RP approach. Baseline demographics, preoperative tumor size, and renal nephrometry scores were similar. The RP approach was associated with shorter operative (150 vs 203 min, p < 0.001) and warm ischemia time (12 vs 21 min, p < 0.001), and less blood loss (20 vs 100 cc, p = 0.002) (Table 1). The RP approach was associated with shorter length of stay (1 vs 2 days, p < 0.001) and less total complications (5.3% vs 19.1%, p = 0.038). Major complication (Clavien-Dindo Grade > 3) rates were similar. There was no difference in positive surgical margin rates or pathologic characteristics. Robotic RP approach for nephron-sparing surgery is feasible for eligible anterior tumors and is associated with favorable perioperative outcomes with preserved negative surgical margin rates.

Solid pseudopapillary neoplasm (SPN) is a rare tumor mostly occurring in the pancreas. They are low-grade malignant tumors of the exocrine pancreas that occasionally metastasize, usually to the liver or peritoneum. Additionally, multiple metastases of extrapancreatic SPN to the liver are extremely rare and have been reported before. This study presents a case of a 13-year-old male patient with retroperitoneal SPN and multiple hepatic metastases. The patient presented with abdominal trauma and underwent enhanced CT, which revealed upper pancreatic occupancy and three hypodense foci in the right lobe of the liver. Moreover, increased spleen size was noted. The patient's serum tumor marker CA125 was increased to 39.00 U/mL ( < 35.0 U/mL), and circulating tumor cells were elevated to 10.2 FU/3 mL ( < 8.7 FU/3 mL). The patient underwent retroperitoneal occupancy resection and splenectomy, followed by resection of liver metastases 7 months after the surgery. Furthermore, multiple liver metastases from retroperitoneal SPN were confirmed postoperatively. The patient recovered for 1 year without tumor recurrence. This case emphasizes the importance of evaluating serum tumor markers and medical imaging in young patients as well as the fact that surgery appears to be the preferred treatment option for multiple metastases in SPN.
