Can lymphadenectomy be omitted in advanced ovarian cancer? A brief review.

Chin Clin Oncol 2020 Jun 3. Epub 2020 Jun 3.

Surgical Oncology, Gynecologic Tumors Division, Instituto Nacional de Cancerología, Mexico City, Mexico.

The indication of systematic lymphadenectomy in advanced ovarian cancer without apparent macroscopic lymph node involvement has been controversial over the past three decades, and the recommendation to perform it or not has been based on multiple retrospective studies, small cohort studies, and few randomized studies with several biases; however, it seems that this controversy has come to an end after the recent publication of a randomized clinical trial. The study of lymph node disease in ovarian cancer has intensified in the last two decades, so far that it was part of the changes of the last update of the International Federation of Gynecology and Obstetrics (FIGO) staging; In this review, a search was made of the available literature to understand the evolution of knowledge about the implications of the realization or not of lymphadenectomy in two scenarios of advanced ovarian cancer (namely, the presence or not of lymph node disease macroscopic), without losing the landscape of the importance of peritoneal disease in these stages, which, as we will see throughout the review, the complete cytoreduction of the tumor remains an integral part of the treatment, since residual disease is one of the most relevant prognostic factors. Nowadays, we can confidently state that systematic lymphadenectomy in patients with advanced ovarian cancer without clinically apparent nodal disease is not necessary, and the presence of macroscopic retroperitoneal lymph node disease should be resected as part of cytoreductive surgery since it will be this and the residual disease that determine the prognosis of the patients.

Two applications for laparoscopic combined ventral and dorsal side approach in the lateral decubitus position: 1) right-modified retroperitoneal lymph node dissection, 2) nephrectomy for horseshoe kidney.

Urology 2020 Jun 4. Epub 2020 Jun 4.

Department of Urology, Japanese Red Cross Wakayama Medical Center, 4-20, Komatsubara-dori, Wakayama City, Wakayama, Japan.

Background: Laparoscopic retroperitoneal lymph node dissection (RPLND) in metastatic testicular cancer is a technically challenging procedure. In right-modified RPLND, retrocaval lymph nodes are often not visible and cannot be adequately dissected using only the transperitoneal approach. In laparoscopic nephrectomy (LN) for horseshoe kidney, the kidney cannot be sufficiently moved due to its connection to the contralateral kidney, and the isthmus and lower poles have separate blood supplies arising from the aorta or iliac artery.

Primary and post-chemotherapy robotic retroperitoneal lymph node dissection for testicular cancer: a review.

Transl Androl Urol 2020 Apr;9(2):949-958

Department of Urology, The James Buchanan Brady Urological Institute, Johns Hopkins University School of Medicine, Baltimore, MD, USA.

Open retroperitoneal lymph node dissection (RPLND) is the gold standard for surgical management of the retroperitoneum in patients with testicular cancer, and is associated with excellent oncologic outcomes and significant morbidity including length of stay. Minimally invasive RPLND, starting with laparoscopic retroperitoneal lymph node dissection in 1992 and now robotic retroperitoneal lymph node dissection in 2006, endeavor to decrease the morbidity of open RPLND while maintaining excellent oncologic outcomes. This review surveys the literature regarding both primary and post-chemotherapy robotic RPLND, emphasizing that while early outcomes are promising, much work needs to be done before widespread use of this technique is implemented.

A Rare Case of Moderately Differentiated Adenocarcinoma With PD-L1 Overexpression and a Heterogeneous LELC Component in the Ascending Colon.

Onco Targets Ther 2020 28;13:791-801. Epub 2020 Jan 28.

First Department of Surgery, Faculty of Medicine, University of Fukui, Fukui 910-1193, Japan.

Background: Lymphoepithelioma-like carcinomas (LELCs), especially colorectal cancers (CRCs), are uncommon pathological phenotypes generally associated with poor aggressiveness and a preferable prognosis. However, PD-L1 overexpression in CRCs is associated with poor outcomes. We report a case of moderately differentiated adenocarcinoma with PD-L1 overexpression, an LELC component, and Crohn's-like lymphoid reaction (CLR) presenting with extreme locoregional aggression and complete remission with chemotherapy after noncurative excision.

Introduction: Neuroendocrine tumours are the most common type of primary small bowel neoplasm. Consensus guidelines recommend a multimodal approach to treatment of such tumours, with aggressive surgical resection remaining the mainstay of management. There is evidence that complete mesocolic excision (CME) of lymph nodes is associated with superior oncological outcomes including longer disease-free survival in patients with colorectal cancer than standard lymph node dissection and there is increasing evidence to suggest that the robotic approach may be superior to laparoscopic or open CME.

Surgical salvage in patients with advanced testicular cancer: indications, risks and outcomes.

Transl Androl Urol 2020 Jan;9(Suppl 1):S83-S90

Department of Urology, Indiana University School of Medicine, Indianapolis, IN, USA.

The purpose of this review is to present a comprehensive and updated review of the literature and summary of the indications, risks and outcomes related to salvage, desperation and late relapse surgery for advanced testicular cancer. After completing a thorough review of the current literature, this review has attempted to provide an overview of the indications for salvage, desperation and late relapse retroperitoneal lymph node dissection (RPLND) followed by a summary of the histopathologic and clinical outcomes regarding each. Recent literature, combined with a significant contribution from historical studies suggest that while testicular cancer is a relatively uncommon malignancy overall, it represents the most common solid organ malignancy for young men.

Surgical strategies for postchemotherapy testis cancer.

Transl Androl Urol 2020 Jan;9(Suppl 1):S74-S82

USC/Norris Comprehensive Cancer Center, Institute of Urology, Los Angeles, CA 90089, USA.

The surgical management of disseminated disease has long been an essential component in the management of patients with testis cancer. While the indications for surgery have been narrowed since the advent of cisplatin based chemotherapy, resection remains essential to provide long-term survival. The indications for surgery vary by histology and rely on adequate preoperative imaging to evaluate for residual disease. Read More

Robot-assisted laparoscopic retroperitoneal lymph node dissection: a minimally invasive surgical approach for testicular cancer.

Transl Androl Urol 2020 Jan;9(Suppl 1):S66-S73

Swedish Urology Group, Seattle, WA, USA.

Retroperitoneal lymph node dissection (RPLND) can been employed as primary treatment for stage I non-seminomatous germ cell tumor (NSGCT) as well as for treatment of post-chemotherapy masses. Open RPLND (O-RPLND) has long been the standard approach for lymphadenectomy, but is associated with significant morbidity. Laparoscopic RPLND (L-RPLND) was developed to mitigate the morbidity associated with O-RPLND, but is a technically challenging procedure requiring significant experience with laparoscopic dissection and suturing to remove lymph nodes behind the great vessels and to control vascular injury.

Current management and management controversies in early- and intermediate-stage of nonseminoma germ cell tumors.

Transl Androl Urol 2020 Jan;9(Suppl 1):S45-S55

Department of Genitourinary Oncology, H. Lee Moffitt Cancer Center and Research Institute, Tampa, FL, USA.

Early stage nonseminomatous germ cell tumor (NSGCT) remains a treatable disease, with stage I cancer specific survival exceeding 95%. Using a risk-adapted approach; active surveillance (AS), adjuvant chemotherapy, and retroperitoneal lymph node dissection (RPLND) all options for treatment; with surveillance being increasingly used. With persistently elevated markers (stage IS), chemotherapy remains the hallmark of treatment. Read More

Contemporary management of early stage testicular seminoma.

Transl Androl Urol 2020 Jan;9(Suppl 1):S36-S44

Department of Radiation Oncology, H. Lee Moffitt Cancer Center and Research Institute, Tampa, FL, USA.

Therapy for early stage testicular seminoma has changed radically over the past several decades. Given high cure rates and clinical trials supporting less active therapy in most cases, close observation after radical orchiectomy is now considered standard of care for clinical stage (CS) IA/IB seminoma, with either radiation therapy (RT) or chemotherapy salvage options possible. For CS IIA/IIB seminoma characterized by non-bulky retroperitoneal lymph node involvement (≤5 cm in greatest dimension), RT or combination chemotherapy are the standard of care. Read More

Defining risk of micrometastatic disease and tumor recurrence in patients with stage I testicular germ cell tumors.

Transl Androl Urol 2020 Jan;9(Suppl 1):S31-S35

Section of Urology, Department of Surgery, The University of Chicago Medicine, Chicago, IL, USA.

There is controversy in the management of patients with clinical stage I non-seminomatous germ cell tumor (NSGCT). Some experts recommend surveillance for all patients regardless of risk factors while others suggest a more risk-adapted approach by using lymphovascular invasion (LVI) and the embryonal component in the primary tumor to select patients most likely to benefit from primary treatment [retroperitoneal lymph node dissection (RPLND) or chemotherapy]. With the surveillance for all strategy, only patients who relapse are treated. Read More

Paratesticular Mesenchymal Malignancies: A Single-Center Case Series, Clinical Management, and Review of Literature.

Integr Cancer Ther 2020 Jan-Dec;19:1534735419900554

Sant'Orsola-Malpighi Hospital, Bologna, Italy.

Primary soft tissue sarcomas arising from the male urinary and genital tract are rare tumors, only accounting for 1% to 2% of all malignancies of the genitourinary tract. Clinical management of advanced disease is lacking in standardized recommendations due to the rarity of the disease. To date, complete and extensive surgery represents the only curative and standardized approach for localized disease, while the impact of retroperitoneal lymphadenectomy and adjuvant treatments on clinical outcomes are still unclear.
