Abstract
BACKGROUND Lateral pelvic lymph node dissection is performed for selected patients with rectal cancer with persistent lateral nodal disease after neoadjuvant therapy. This technique has been slow to be adopted in the West because of concerns regarding technical difficulty. This is the first report on the learning curve for lateral pelvic lymph node dissection in the United States or Europe. OBJECTIVE This study aimed to analyze the learning curve associated with robotic lateral pelvic lymph node dissection. DESIGN Retrospective observational cohort. SETTING Tertiary academic cancer center. PATIENTS Consecutive patients from 2012 to 2021. INTERVENTION All patients underwent robotic lateral pelvic lymph node dissection. MAIN OUTCOME MEASURES The primary end points were the learning curves for the maximum number of nodes retrieved and urinary retention, which was evaluated with simple cumulative sum and 2-sided Bernoulli cumulative sum charts. RESULTS Fifty-four procedures were included. A single-surgeon learning curve (n = 35) and an institutional learning curve are presented in the analysis. In the single-surgeon learning curve, a turning point marking the end of a learning phase was detected at the 12th procedure for the number of retrieved nodes and at the 20th procedure for urinary retention. In the institutional learning curve analysis, 2 turning points were identified at the 13th procedure, indicating progressive improvements for the number of retrieved nodes, and at the 27th procedure for urinary retention. No sustained alarm signals were detected at any time point. LIMITATIONS The retrospective nature, small sample size, and the referral center nature of the reporting institution may limit generalizability. CONCLUSIONS In a setting of institutional experience with robotic colorectal surgery, including beyond total mesorectal excision resections, the learning curve for robotic lateral pelvic lymph node dissection is acceptably short. Our results demonstrate the feasibility of the acquisition of this technique in a controlled setting, with sufficient case volume and proctoring to optimize the learning curve. See Video Abstract. LA CURVA DE APRENDIZAJE DE LA DISECCIN ROBTICA DE LOS GANGLIOS LINFTICOS PLVICOS LATERALES EN EL CNCER DE RECTO UNA VISIN DESDE OCCIDENTE ANTECEDENTES:La disección lateral de los ganglios linfáticos pélvicos se realiza en pacientes seleccionados con cáncer de recto con enfermedad ganglionar lateral persistente tras el tratamiento neoadyuvante. La adopción de esta técnica en Occidente ha sido lenta debido a la preocupación por su dificultad técnica. Éste es el primer informe sobre la curva de aprendizaje de la disección de los ganglios linfáticos pélvicos laterales en EE.UU. o Europa.OBJETIVO:El objetivo de este estudio fue analizar la curva de aprendizaje asociada a la disección robótica de los ganglios linfáticos pélvicos laterales.DISEÑO:Cohorte observacional retrospectiva.LUGAR:Centro oncológico académico terciario.PACIENTES:Pacientes consecutivos desde 2012 al 2021.INTERVENCIÓN:Todos los pacientes fueron sometieron a disección robótica de ganglios linfáticos pélvicos laterales.PRINCIPALES MEDIDAS DE RESULTADO:Los criterios de valoración primarios fueron las curvas de aprendizaje tomando en cuenta el mayor número de ganglios recuperados y la retención urinaria que fueron evaluados con gráficos de suma acumulativa simple y de suma acumulativa de Bernoulli de dos caras.RESULTADOS:Fueron incluidos 54 procedimientos. En el análisis se presentan una curva de aprendizaje de un solo cirujano (n = 35) y una curva de aprendizaje institucional. En la curva de aprendizaje de un solo cirujano, se detectó un punto de inflexión que marcaba el final de una fase de aprendizaje en el duodécimo procedimiento para el número de ganglios extraídos y en el vigésimo para la retención urinaria. En el análisis de la curva de aprendizaje institucional, se identificaron dos puntos de inflexión en las intervenciones 13.ª y 26.ª, que indicaron mejoras progresivas en el número de ganglios extraídos, y en la 27.ª en la retención urinaria. No se detectaron señales de alarma sostenidas en ningún momento.LIMITACIONES:La naturaleza retrospectiva, el pequeño tamaño de la muestra y la naturaleza de centro de referencia de la institución informante que pueden limitar la capacidad de generalizarse.CONCLUSIONES:En un entorno de experiencia institucional con cirugía robótica colorrectal incluyendo más allá de las resecciones TME, la curva de aprendizaje para la disección robótica de ganglios linfáticos pélvicos laterales es aceptablemente corta. Nuestros resultados demuestran la viabilidad de la adquisición de esta técnica en un entorno controlado, con un volumen de casos suficiente y una supervisión que puede optimizar la curva de aprendizaje.

Abstract
Background This study aimed to evaluate the efficacy of lateral lymph node dissection (LLND) for rectal cancer by comparing the local control in patients with and without pathological lateral lymph node metastasis (LLNM). Methods We included 189 patients with rectal cancer who underwent total mesorectal excision and LLND at 13 institutions between 2017 and 2019. Patients with and without pathological LLNM were defined as the pLLNM (+) and (-) groups, respectively. Propensity score-matching helped to balance the basic characteristics of both groups. The incidences of local recurrence (LR) and lateral lymph node recurrence (LLNR) were compared between the groups. Results In the entire cohort, 39 of the 189 patients had pathological LLNM. The 3-year LR and LLNR rates were 18.3% and 4.0% (p = 0.01) and 7.7% and 3.3% (p = 0.22) in the pLLNM (+) and (-) groups, respectively. After propensity score matching, the data from 62 patients were analyzed. No significant differences in LR or LLNR were observed between both groups. The 3-year LR and LLNR rates were 16.4% and 9.8% (p = 0.46) and 9.7% and 9.8% (p = 0.99) in the pLLNM (+) and (-) groups, respectively. Conclusion LLND would lead to comparable local control in the pLLNM (+) and (-) groups if the clinicopathological characteristics except for LLNM are similar.

Abstract
The management of rectal cancer has undergone significant changes over the past 50 years, and this has been associated with major improvements in overall outcomes and quality of life. From standardization of total mesorectal excision to refinements in radiation delivery and shifting of chemoradiotherapy treatment to favor a neoadjuvant approach, as well as the development of targeted chemotherapeutics, these management strategies have continually aimed to achieve locoregional and systemic control while limiting adverse effects and enhance overall survival. This article highlights evolving aspects of rectal cancer therapy including improved staging modalities, total neoadjuvant therapy, the role of short-course and more selective radiotherapy strategies, as well as organ preservation. We also discuss the evolving role of minimally invasive surgery and comment on lateral pelvic lymph node dissection. Key message Rectal cancer management is constantly evolving through refinements in radiation timing and delivery, modification of chemoradiotherapy treatment schedules, and increasing utilization of minimally invasive surgical techniques and organ preservation strategies. This manuscript aims to provide a synopsis of recent changes in the management of rectal cancer, highlighting contemporary modifications in neoadjuvant approaches and surgical management to enhance the knowledge of surgeons who care for this challenging population.

Can neoadjuvant chemoradiotherapy before lateral pelvic lymph node dissection improve local control and prognosis in rectal cancer patients with clinically suspected lateral lymph node metastasis? A multicenter lateral node study in China. BMC Cancer 2024; 24:115. [PMID: 38263067 PMCID: PMC10804599 DOI: 10.1186/s12885-024-11867-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 01/10/2024] [Indexed: 01/25/2024] Open
Abstract
AIMS Selective lateral pelvic lymph node (LPN) dissection (LPND) following neoadjuvant chemoradiotherapy (nCRT) for rectal cancer is widely recognized. This study aimed to determine the effects of nCRT before LPND on local control and prognosis of rectal cancer patients. MATERIALS AND METHODS Data were retrieved from a prospective database for rectal cancer patients with clinical LPN metastasis receiving total mesorectal excision and LPND at three institutions between January 2012 and December 2019. Selection bias was minimized using propensity score matching (PSM) and short-term and clinical outcomes were compared. RESULTS Patients (n = 213) were enrolled and grouped as either nCRT (n = 97) or non-nCRT (n = 116). PSM was used to identify 83 matched pairs. In the matched cohort, nCRT patients had a longer operation duration (310.6 vs. 265.0 min, P = 0.001), lower pathological LPN metastasis rate (32.5% vs. 48.2%, P = 0.040), and fewer harvested lymph nodes (22 vs. 25, P = 0.018) compared to the non-nCRT group. However, after PSM, the two groups had similar estimated overall 3-year survival (79.5% vs. 80.7%, P = 0.922), 3-year disease-free survival (66.1% vs. 65.5, P = 0.820), and 3-year local recurrence-free survival (88.6% vs. 89.7%, P = 0.927). Distant metastasis was the predominant recurrence pattern in the overall (45/58, 77.6%) and matched (33/44, 75.0%) cohorts. CONCLUSIONS LPND without nCRT is effective and sufficient in preventing local recurrence in patients with LPN metastases. Future prospective randomized controlled studies are warranted to confirm these findings. Since systemic metastasis is the predominant recurrence pattern in patients with LPN metastasis post-LPND, improved perioperative systemic chemotherapy is needed to prevent micrometastasis.

Neoadjuvant S-1 and oxaliplatin plus bevacizumab therapy for high-risk locally advanced rectal cancer: A prospective multicenter phase II study. Ann Gastroenterol Surg 2024; 8:71-79. [PMID: 38250676 PMCID: PMC10797815 DOI: 10.1002/ags3.12720] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 06/05/2023] [Accepted: 07/06/2023] [Indexed: 01/23/2024] Open
Abstract
Aim We report the short/mid-term results of surgery for high-risk locally advanced rectal cancer (LARC) after neoadjuvant chemotherapy (NAC, four courses of S-1 + oxaliplatin+ bevacizumab) without radiotherapy with the primary aim of ypT0-2. Methods High-risk LARC was defined as cT4b, mesorectal fascia (MRF) ≤1 mm (MRF+), or lateral lymph node metastasis (cLLN+) on high-resolution MRI. The planned 32 cases from April 2018 to December 2021 were all included. Results There were 10 patients at cT4b (31.2%), 26 MRF+ (81.3%), and 22 cLLN+ (68.8%). Thirteen (40.6%) underwent NAC after a colostomy for stenosis. NAC was completed in 26 (81.2%) cases. Grade 3 or higher adverse events occurred in six (18.7%). One patient developed progressive disease (3.2%). Eleven were ycT0-3MRF-LLN- (34.3%). Curative-intent surgery was performed on 31, with sphincter-preserving surgery in 20, abdominoperineal resection in nine, total pelvic exenteration in two, and lateral lymph node dissection in 24. Two had R1/2 resection (6.4%). A Grade 3 or higher postoperative complication rate occurred in 3.2%. Pathological complete response and ypT0-2 rates were 12.9% and 45.1%. Three-year disease-free survival rates (3yDFS) for ypT0-2 and ypT ≥3 were 81.2%, 46.6% (p = 0.061), and 3-year local recurrence rates (3yLR) were 0%, 48.8% (p = 0.015). 3yDFS for ycT0-3MRF-LLN- and ycT4/MRF+/LLN+ were 87.5%, 48.0% (p = 0.031) and 3yLR were 0%, 42.8% (p = 0.045). Conclusion NAC yielded a clinically significant effect in about half of high-risk LARC patients. If NAC alone is ineffective, radiotherapy should be added, even if extended surgery is intended.

Abstract
In the paradigm shift related to rectal cancer treatment, we have to understand a variety of new emerging topics to provide appropriate treatment for individual patients as precision medicine. However, information on surgery, genomic medicine, and pharmacotherapy is highly specialized and subdivided, creating a barrier to achieving thorough knowledge. In this review, we summarize the perspective for rectal cancer treatment and management from the current standard-of-care to the latest findings to help optimize treatment strategy.

Abstract
BACKGROUND Although lateral pelvic lymph node dissection (LLND) might be an effective approach for patients with rectal cancer with lateral lymph node metastasis, it is technically challenging because of the anatomical complexity and location of the deep pelvis. An assistance by transanal approach might be useful for a successful LLND. METHODS From September 2016 to May 2021, 39 patients with low rectal cancer underwent transanal total mesorectal excision with LLND. Among them, 18 patients underwent LLND using a conventional laparoscopic approach alone, while the remaining 21 underwent LLND using both conventional and transanal approaches. Their clinical outcomes were retrospectively compared. RESULTS The operation time for LLND on each side was significantly shorter in the transanal group (105 min vs. 54 min, P < 0.001). The intraoperative blood loss was also significantly less in the transanal group (40 g vs. 0 g, P = 0.031). The rate of overall postoperative complications ≥ grade II according to the Clavien-Dindo classification was significantly less in the transanal group (66.7% vs. 28.6%, odds ratio: 5.000, 95% confidence intervals: 1.313-19.047, P = 0.040). The number of harvested lateral lymph nodes in both groups was similar (8.5 vs. 8, P = 0.544). CONCLUSION The transanal approach for LLND reduced operative time, blood loss, and morbidity compared with the conventional approach alone in a cohort of patients with rectal cancer.

Abstract
Rectal cancer is the eighth most common malignancy worldwide. With the introduction of total mesorectal excision (TME) and neoadjuvant chemoradiation (NCRT), intrapelvic local control has been remarkably improved. However, lateral pelvic recurrence remains problematic, especially in patients with clinically suspicious lateral pelvic lymph node (LPLN). LPLN dissection has been applied for the management of LPLN metastasis, mainly in Japan and other Eastern countries, while the role of NCRT is more emphasized and LPLN dissection is performed in very limited cases in Western countries. However, the optimal management strategy for patients with rectal cancer with suspicious LPLN metastasis has not been determined. Herein, we review the latest studies on the optimal management of LPLN metastasis to suggest the most appropriate treatment policies according to current evidence and discuss future research directions.

Efficacy and Safety of Radical Resection of Rectal Cancer Combined with Selective Lateral Lymph Node Dissection in the Treatment of Low Rectal Cancer under Meta-analysis. CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:8456677.

Abstract
Rectal cancer mostly occurs in the middle and low position in China, and many anatomical evidence has confirmed that Lateral Lymph Node Metastasis (LLNM) exists in middle and low rectal cancer. Laparoscopic surgery can penetrate into the pelvic cavity and magnify and narrow the visual field, which is helpful for lymph node dissection and vascular nerve protection, while it has minimally invasive characteristics and is considered to be more suitable for LLND. Relevant articles published from January 2000 to May 2022 are searched using "Rectal cancer, Lateral lymph node dissection, Radical resection of rectal cancer, Low rectal cancer, Laparoscopic therapy, Treatment of rectal cancer" as test terms, analyzed and assessed using Rev Man 5.3 software and Stata software to assess the risk bias of included references, and heterogeneity among each study is evaluated using Q test and heterogeneity (I2). The experimental results show that there is no heterogeneity among the studies (I2 = 8.46%). The heterogeneity of lymphatic metastasis in the included literature is evaluated, and the results show that there is heterogeneity between the studies (I2 = 52.06%).

We aimed to investigate the prognostic significance and effective range of dissection for the LPN dissection (LPND) in rectal cancer patients with LPN metastasis. Materials and methods Through this large, multicenter retrospective cohort study, we evaluated the therapeutic effect of LPND. From January 2012 to December 2019, 387 rectal cancer patients with clinical evidence of LPN metastasis who underwent total mesorectal excision with LPND were included in the study. According to pathological findings, they were divided into negative (n = 296) and positive (n = 91) LPN groups. Primary endpoints were 3-year overall survival (OS), recurrence-free survival (RFS), and local recurrence-free survival (LRFS). Results The OS, RFS, and LRFS in the positive group were significantly worse than those in the negative group; However, LPN metastases were not independent prognostic risk factors for LRFS (hazard ratio [HR]: 2.42; 95% confidence interval [CI], 0.77–7.64; P=0.132). Among patients with pathological LPN metastases, LPN metastases to the common and external iliac arteries were independent prognostic risk factors both for OS (HR: 4.74; 95% CI, 1.74–12.90; P=0.002) and RFS (HR: 2.70; 95% CI, 1.16–6.29; P=0.021). No significant difference was observed in the 3-year OS (72.3% vs. 70.2%, P=0.775) and RFS rates (60.9% vs. 52.6%, P=0.408) between patients with metastases to the obturator or internal iliac arteries and patients at N2b stage. Conclusions LPND may be effective in controlling local recurrence in patients with LPN metastasis but not systemic metastases. Patients with LPN metastasis limited to the internal iliac and obturator regions achieve a long-term survival benefit from LPND, and their prognoses may be comparable to those at the N2b stage. Further metastasis to the external iliac or common iliac region should be considered systemic disease, and LPND should be avoided. Clinical Trial Registration ClinicalTrials.gov, identifier NCT04850027.

Abstract
BACKGROUND Lavage cytology is a method to detect cancer cells released within the abdominal cavity. It has been widely utilized, in particular, for gastric cancer. However, its clinical significance has not yet been determined in colorectal cancer. OBJECTIVE This study aimed to investigate the frequency of lavage cytology positivity and its influence on the prognosis of patients with colorectal cancer. DESIGN This is a single-institution retrospective observational study. SETTING This study was conducted at a comprehensive cancer center. PATIENTS We retrospectively analyzed 3135 colorectal cancer cases from 2007 to 2013 at our institution. Intraoperative peritoneal washing cytology was performed just after the start of the operation. Fluids were centrifuged for 5 minutes at 2500 rotations per minute, cell pellets were smeared on microscope glass slides, and Papanicolaou staining was performed. MAIN OUTCOME MEASURES The primary outcome was the 5-year overall survival rate. The secondary outcome was the 5-year recurrence rate. RESULTS Lavage cytology positivity was detected in 19 (2.0%) and 86 (16.9%) cases of stage III and IV colorectal cancer; however, no positive cases were found in stage I and II colorectal cancer. Lavage cytology positivity was an independent prognostic factor in stage III and IV colorectal cancer in the multivariate analysis (5-year mortality HR 3.59 [1.69-7.64] in stage III, 2.23 [1.15-4.31] in stage IV). The prognosis of the 5-year survival rate was significantly worse in the lavage cytology-positive group in stages III and IV. In terms of recurrence, the results of the lavage cytology-positive group in stage III were similar to those of the lavage cytology-positive/negative group in stage IV (73.7%, 70.0%, and 75.0%). LIMITATIONS This study was limited by its retrospective study design. CONCLUSIONS Lavage cytology positivity is an independent prognostic and regulatory factor of stage IV colorectal cancer.

Stereotactic navigation using registration based on intra-abdominal landmarks in robotic-assisted lateral pelvic lymph node dissection. Tech Coloproctol 2022; 26:735-743. [PMID: 35676544 DOI: 10.1007/s10151-022-02643-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Accepted: 05/18/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND We carried out robot-assisted lateral pelvic lymph node dissection (LPLND) for rectal cancer with a stereotactic navigation system. The purpose of this study was to evaluate the accuracy and feasibility of the system. METHODS We constructed a navigation system based on the Polaris Spectra optical tracking device (Northern Digital Inc., Canada) and the open-source software 3D Slicer (version 3.8.1; http://www.slicer.org ). We used the landmark-based registration method for patient-to-image registration. Body surface landmarks and intra-abdominal landmarks were used. We evaluated the time required for registration and target registration error (TRE; the distance between corresponding points after registration) for the root of the superior gluteal artery the root of the obturator or superior vesical artery, and the obturator foramen during minimally invasive LPLND for rectal cancer. Five patients who had LPLND for rectal cancer at the University of Tokyo Hospital between September 2020 and May 2021 were enrolled. RESULTS The mean time required for registration was 49 s with the body surface landmarks and 88 s with the intra-abdominal landmarks. The mean TRE improved markedly when the registration was performed using intra-abdominal landmarks. The mean TRE of the root of the superior gluteal artery, the root of the obturator or superior vesical artery, and the obturator foramen were 55.8 mm, 53.4 mm, and 55.2 mm with the body surface landmarks and 11.8 mm, 10.0 mm, and 12.6 mm with the intra-abdominal landmarks, respectively. There were no adverse events related to the registration process. CONCLUSIONS When stereotactic navigation systems are used for minimally invasive LPLND, the use of intra-abdominal landmarks for registration is feasible and may allow simpler and more accurate navigation than the use of body surface landmarks.

Risk factors and prognostic significance of lateral pelvic lymph node dissection after neoadjuvant chemoradiotherapy for rectal patients with clinically suspected lateral lymph node metastasis.

[PMID: 34961494 PMCID: PMC8714447 DOI: 10.1186/s12893-021-01443-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Accepted: 12/17/2021] [Indexed: 11/10/2022] Open
Abstract
AIM It is still controversial whether the addition of lateral pelvic lymph node (LPN) dissection (LPND) to total mesorectal excision (TME) can provide a survival benefit after neoadjuvant chemoradiotherapy (nCRT) in rectal cancer patients with pathological lateral lymph node metastasis (LPNM). METHODS Patients with clinically suspected LPNM who underwent nCRT followed by TME + LPND were systematically reviewed and divided into the positive LPN group (n = 15) and the negative LPN group (n = 58). Baseline characteristics, clinicopathological data and survival outcomes were collected and analysed. RESULTS Of the 73 patients undergoing TME + LPND after nCRT, the pathological LPNM rate was 20.5% (15/73). Multivariate analysis showed that a post-nCRT LPN short diameter ≥ 7 mm (OR 49.65; 95% CI 3.98-619.1; P = 0.002) and lymphatic invasion (OR 9.23; 95% CI 1.28-66.35; P = 0.027) were independent risk factors for pathological LPNM. The overall recurrence rate of patients with LPNM was significantly higher than that of patients without LPNM (60.0% vs 27.6%, P = 0.018). Multivariate regression analysis identified that LPNM was an independent risk factor not only for overall survival (OS) (HR 3.82; 95% CI 1.19-12.25; P = 0.024) but also for disease-free survival (DFS) (HR 2.33; 95% CI 1.02-5.14; P = 0.044). Moreover, N1-N2 stage was another independent risk factor for OS (HR 7.41; 95% CI 1.63-33.75; P = 0.010). CONCLUSIONS Post-nCRT LPN short diameter ≥ 7 mm and lymphatic invasion were risk factors for pathological LPNM after nCRT. Furthermore, patients with pathological LPNM still show an elevated overall recurrence rate and poor prognosis after TME + LPND. Strict patient selection and intensive perioperative chemotherapy are crucial factors to ensure the efficacy of LPND.

Abstract
Purpose The surgical treatment of advanced low rectal cancer remains controversial. Extended lymphadenectomy (EL) is the preferred option in the East, especially in Japan, while neoadjuvant radiotherapy is the treatment of choice in the West. This review was undertaken to review available evidence supporting each of the therapies. Methods All studies looking at EL were included in this review. A comprehensive search was conducted as per PRISMA guidelines. Primary outcome was defined as 5-year overall survival, with secondary outcomes including 3-year overall survival, 3- and 5-year disease-free survival, length of operation, and number of complications. Results Thirty-one studies met the inclusion criteria. There was no significant publication bias. There was statistically significant difference in 5-year survival for patient who underwent EL (odds ratio, 1.34; 95 confidence interval, 0.09–0.5; P=0.006). There were no differences noted in secondary outcomes except for length of the operations. Conclusion There is evidence supporting EL in rectal cancer; however, it is difficult to interpret and not easily transferable to a Western population. Further research is necessary on this important topic.

Abstract
Background Lateral pelvic lymph node dissection (LPLD) in rectal cancer has been carried out in several major centers. However, there are still many controversial issues regarding this method such as feasibility, safety, and oncological outcome. Objective The aim of this study was to evaluate the short-term outcomes, safety, and feasibility of LPLD. Methods This was a retrospective study. A total of 117 patients with lower rectal cancer (clinical stage II/III) below the peritoneal reflection underwent surgery between January 2019 and November 2020 at 108 Military Central Hospital, Hanoi, Vietnam. Results Total amount of 25 patients underwent laparoscopic total mesorectal excision (TME) plus LPLD and 92 patients underwent laparoscopic TME without LPLD. The rate of lateral pelvic lymph node metastasis in the LPLD group was 16% (4/25), of which 12% (3/25) were on the left side and 4% (1/25) were on the right side. The rate of intraoperative complications in the LPLD group was significantly higher at 16.0% (4/25) compared with 3.3% (3/92) in the TME only group (p = 0.037). There were no statistically significant differences in the rate of postoperative complications between the two groups (24.0% of patients in the LPLD group compared with 26.1% patients in the no LPLD group, p = 0.832). Conclusion Pelvic lymphadenectomy has an important role in the treatment of advanced lower rectal cancer. LPLD is a safe and feasible procedure. However, it is necessary to study a larger number of patients with a longer follow-up period to fully evaluate oncological outcomes.

Abstract
The current status and future prospects for diagnosis and treatment of lateral pelvic lymph node (LPLN) metastasis of rectal cancer are described in this review. Magnetic resonance imaging (MRI) is recommended for the diagnosis of LPLN metastasis. A LPLN-positive status on MRI is a strong risk factor for metastasis, and evaluation by MRI is important for deciding treatment strategy. LPLN dissection (LPLD) has an advantage of reducing recurrence in the lateral pelvis but also has a disadvantage of complications; therefore, LPLD may not be appropriate for cases that are less likely to have LPLN metastasis. Radiation therapy (RT) and chemoradiation therapy (CRT) have limited effects in cases with suspected LPLN metastasis, but a combination of preoperative CRT and LPLD may improve the treatment outcome. Thus, RT and CRT plus selective LPLD may be a rational strategy to omit unnecessary LPLD and produce a favorable treatment outcome.

Abstract
BACKGROUND AND AIMS The benefit of lateral pelvic lymph node dissection (LPLD) for locally advanced rectal cancer remains controversial. This meta-analysis aimed to evaluate the prognostic value of LPLD in patients with locally advanced rectal cancer. METHODS We performed a systematic search in PubMed, Embase, and the Cochrane Library for publications comparing radical resection plus LPLD (LPLD group) with single radical resection (non-LPLD group) for locally advanced rectal cancer. A total of 15 studies satisfied our inclusion criteria and were assessed. Random-effects and fixed-effects meta-analytical models were used where indicated, and between-study heterogeneity was assessed. RESULTS LPLD significantly increased grade 3-4 postoperative complications (odds ratio [OR]1.44, 95% CI 1.03-2.02; P = 0.03) compared with non-LPLD. There were no significant differences in 5-y overall survival (hazard ratio = 0.90, 95% CI 0.77-1.05; P = 0.17), 5-y disease-free survival (hazard ratio 1.12, 95% CI 0.60-2.09; P = 0.73), local recurrence (OR 0.89, 95% CI 0.53-1.51; P = 0.68) or distant recurrence (OR 0.85, 95% CI 0.64-1.12; P = 0.24). CONCLUSIONS We found that LPLD significantly increased grade 3-4 postoperative complications but did not increase 5-y overall survival or 5-y disease-free survival compared with single radical resection for locally advanced rectal cancer. Furthermore, it did not decrease the local recurrence or distant recurrence rates. Thus, more multicenter large-scale randomized controlled trials should be conducted to further explore whether the long-term survival benefits of LPLD truly exist.

Abstract
BACKGROUND Total mesorectal excision is the gold standard treatment of mid- and low-lying rectal cancer. Lateral pelvic lymph node dissection has been suggested as an approach to decrease recurrence and improve survival. Our meta-analysis presented here aimed to review the current outcomes of lateral pelvic lymph node dissection and total mesorectal excision in comparison with total mesorectal excision alone. METHODS A systematic literature search querying electronic databases was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. We reviewed articles that reported the outcomes of lateral pelvic lymph node dissection combined with total mesorectal excision in comparison with total mesorectal excision alone. The main outcome measures were local recurrence, distant metastasis, overall and disease free-survival, and complications. RESULTS This systematic review included 29 studies of 10,646 patients. Of those patients, 39.4% underwent total mesorectal excision with lateral pelvic lymph node dissection. The median operation time for the lateral pelvic lymph node dissection + total mesorectal excision was significantly longer than total mesorectal excision alone (360 minutes versus 294.7 minutes, P = .02). Lateral pelvic lymph node dissection + total mesorectal excision was associated with higher odds of overall complications (odds ratio = 1.48, 95% confidence interval: 1.18-1.87, P < .001) and urinary dysfunction (odds ratio = 2.1, 95% confidence interval: 1.21-3.67, P = .008) than total mesorectal excision alone. Both groups had similar rates of male sexual dysfunction (odds ratio = 1.62, 95% confidence interval: 0.94-2.79, P = .08), anastomotic leakage (odds ratio = 1.15, 95% confidence interval: 0.69-1.93, P = .59), local recurrence (hazard ratio = 0.96, 95% confidence interval: 0.75-1.25, P = .79), distant metastasis (hazard ratio = 0.96, 95% confidence interval: 0.76-1.2, P = .72), overall survival (hazard ratio = 1.056, 95% confidence interval: 0.98-1.13, P = .13), and disease-free survival (hazard ratio = 1.02, 95% confidence interval: 0.97-1.07, P = .37). CONCLUSION Lateral pelvic lymph node dissection was not associated with a significant reduction of recurrence rates or improvement in survival as compared with total mesorectal excision alone; however, LPLND was associated with longer operation time and increased complication rate.

Robotic lateral pelvic lymph node dissection after chemoradiation for rectal cancer: a Western perspective. Colorectal Dis 2020; 22:2049-2056. [PMID: 32892473 DOI: 10.1111/codi.15350] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2020] [Revised: 08/06/2020] [Accepted: 08/25/2020] [Indexed: 12/15/2022]
Abstract
AIM There are limited outcome data for lateral pelvic lymph node dissection (LPLND) following neoadjuvant chemoradiotherapy (nCRT), particularly in the West. Our aim was to evaluate the short-term perioperative and oncological outcomes of robotic LPLND at a single cancer centre. METHOD A retrospective analysis of a prospective database of consecutive patients undergoing robotic LPLND for rectal cancer between November 2012 and February 2020 was performed. The main outcomes were short-term perioperative and oncological outcomes. Major morbidity was defined as Clavien-Dindo grade 3 or above. RESULTS Forty patients underwent robotic LPLND during the study period. The mean age was 54 years (SD ± 15 years) and 13 (31.0%) were female. The median body mass index was 28.6 kg/m2 (IQR 25.5-32.6 kg/m2 ). Neoadjuvant CRT was performed in all patients. Resection of the primary rectal cancer and concurrent LPLND occurred in 36 (90.0%) patients, whilst the remaining 4 (10.0%) patients had subsequent LPLND after prior rectal resection. The median operating time was 420 min (IQR 313-540 min), estimated blood loss was 150 ml (IQR 55-200 ml) and length of hospital stay was 4 days (IQR 3-6 days). The major morbidity rate was 10.0% (n = 4). The median lymph node harvest from the LPLND was 6 (IQR 3-9) and 13 (32.5%) patients had one or more positive LPLNs. The median follow-up was 16 months (IQR 5-33 months), with 1 (2.5%) local central recurrence and 7 (17.5%) patients developing distant disease, resulting in 3 (7.5%) deaths. CONCLUSION Robotic LPLND for rectal cancer can be performed in Western patients to completely resect extra-mesorectal LPLNs and is associated with acceptable perioperative morbidity.

Abstract
Lateral pelvic lymph nodes (LPLN) are a major site for local recurrence following curative resection for low locally advanced rectal cancer. Ongoing advances in imaging techniques have improved predicting LPLN metastasis (LPLNM) during pre-operative staging. However, there is ongoing debate on optimal management of this subgroup of patients with variation between guidance of different societies. In Japan, LPLNM is considered as local disease and addressed by lateral pelvic node dissection (LPLND) in addition to total mesorectal excision (TME). However, in the west, LPLNM is considered as metastatic disease and those patients are offered neoadjuvant chemoradiotherapy (nCRT) followed by TME surgery. The potential surgical risks and morbidity associated with LPLND as well as the uncertainty of the oncological outcome have raised the concern that patients with locally advanced low rectal cancer with LPLNM could be over or under-treated. A comprehensive review of literature was performed, summarizing the current evidence on available modalities for predicting LPLNM, the role of LPLND in the management of advanced low rectal cancer and the available surgical approaches with their impact on surgical and oncological outcomes. LPLND is associated with increased operative time, blood loss and post-operative morbidity. The potential benefits for local disease control and survival still awaits high quality studies. There has been increasing number of reports of the use minimally invasive approaches in LPLND in an attempt to reduce post-operative complications. There is need for high quality evidence to define the role of LPLND in management of patients with advanced low rectal cancer.

Feasibility and safety of laparoscopic lateral pelvic lymph node dissection for locally recurrent rectal cancer and risk factors for re-recurrence. Asian J Endosc Surg 2020; 13:489-497. [PMID: 31854108 DOI: 10.1111/ases.12778] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Revised: 11/18/2019] [Accepted: 11/26/2019] [Indexed: 12/15/2022]
Abstract
INTRODUCTION Lateral pelvic lymph node (LPLN) metastasis is considered a distant metastasis. It is often treated by systemic chemotherapy and/or radiation therapy, but complete radical resection of LPLN metastasis can sometimes achieve cure. However, the safety and efficacy of radical resection for recurrent LPLN after curative rectal surgery have not been well elucidated. Therefore, we evaluated the feasibility of laparoscopic radical surgery for recurrent LPLN compared with the conventional open approach and assessed oncological outcomes between patients with and without re-recurrence. METHODS We retrospectively reviewed 17 cases (4 open, 13 laparoscopic) who underwent radical resection for LPLN metastasis after curative rectal surgery between July 2012 and August 2016 at the National Hospital Organization Osaka National Hospital. Operative factors and short-term outcomes were compared. Oncological outcome was evaluated based on the pathologic response to preoperative adjuvant therapy. RESULTS The laparoscopic group's median blood loss and C-reactive protein elevation were lower than that of the open group on postoperative day 3. The laparoscopic group also had a shorter postoperative hospital stay. The median operative time, R0 resection rate, and morbidity rate were similar between the two groups. Local re-recurrence after LPLN resection occurred more frequently in pathologic non-responders than responders. CONCLUSION Laparoscopic surgery for LPLN metastasis is feasible and less invasive than open surgery. Laparoscopic radical resection of LPLN may be justified for curative intent. Patients with incomplete pathologic response to neoadjuvant therapy have a greater risk of re-recurrence.

Short- and long-term outcomes of laparoscopic versus open lateral lymph node dissection for locally advanced middle/lower rectal cancer using a propensity score-matched analysis. Surg Endosc 2020; 35:4427-4435.

Abstract
BACKGROUND There are few reports on large-scale trials for the long-term outcomes regarding laparoscopic lateral lymph node dissection (LLND). We evaluated the short- and long-term outcomes of laparoscopic versus open LLND for locally advanced middle/lower rectal cancer using a propensity score-matched analysis. METHODS From January 2005 to December 2016, consecutive clinical stage II to III middle/lower rectal cancer patients who underwent total mesorectal excision (TME) plus LLND were retrospectively collected at three institutions. Laparoscopic LLND was compared with open LLND for the surgical and oncological outcomes, including the long-term survival, using a propensity score-matched analysis. RESULTS A total of 325 patients were collected. There were 142 patients who underwent open TME plus LLND (open group) and 183 patients who underwent laparoscopic TME plus LLND (laparoscopic group). A total of 93 patients each were matched to each group. Compared to the open group, the laparoscopic group had a significantly longer operative time (327 vs. 377 min; p = 0.002) but significantly less blood loss (540 vs. 50 ml; p < 0.001), fewer Clavian-Dindo grade ≥ 2 postoperative complications (49.5% vs. 34.4%; p = 0.037) and shorter postoperative hospital stay (18 vs. 14 days; p = 0.008). Furthermore, the rate of urinary retention was significantly lower in the laparoscopic group than in the open group (16.1% vs. 6.5%; p = 0.037). The estimated 3-year overall survival, relapse-free survival, and cumulative incidence of local recurrence were 91.4%, 73.1%, and 3.4% in the open group and 90.3%, 74.2%, and 4.3% in the laparoscopic group (p = 0.879, 0.893, 0.999), respectively. CONCLUSIONS This study showed that laparoscopic LLND had advantages over an open approach, such as less blood loss, fewer postoperative complications, and a shorter postoperative hospital stay, and the oncologic outcomes were similar to the open approach. Laparoscopic LLND could be a viable standard approach to LLND for advanced middle/lower rectal cancer surgery.

Abstract
PURPOSE Treatment of lateral lymph node metastasis in rectal cancer is still under debate. While these nodes are routinely resected by Japanese teams, neoadjuvant radiochemotherapy alone is performed in Western countries. We aimed to systematically report the current literature assessing the overall and disease-free survivals of patients with rectal cancer treated with total mesorectal resection (TME) with or without lateral lymph node dissection (LLND). METHODS MEDLINE/Pubmed, Embase, Cochrane, and Web of Science were searched from database implementation until 19 January 2019. Studies reporting overall survival or recurrence-free survival in patients with LLND for rectal cancer were included. We excluded studies including patients with recurrent rectal cancer, multivisceral resection, and/or without control group (patients with rectal surgery without LLND). RESULTS Eleven studies were included, accounting for a total of 4159 patients. Overall survival ranged between 55.6 and 92.6% for TME with LLND versus 49.2 and 90.2% for TME alone, with one study reporting statistically significant benefit of LLND. Recurrence-free survival ranged between 58.3 and 74.1% for TME with LLND versus 39.5 and 76.5% for TME alone. Two studies showed statistically significant differences between the two strategies, one randomized controlled trial showed improved recurrence-free survival in TME alone group (74.5% versus 74.1% with LLND at 5 years) and one observational retrospective study reported increased recurrence-free survival with more extensive resection (65.4% versus 39.5% without LLND, at 5 years). CONCLUSION Benefits of LLND are not clear and further randomized controlled trials should be performed to determine which strategy would allow improving survival in rectal cancer patients. TRIAL REGISTRATION The study protocol was registered in PROSPERO prior to study screening (CRD42019123181) and published in September 2019.

Abstract
PURPOSES Lateral pelvic lymph node (LPLN) dissection represents a technically challenging procedure with a high potential risk of surgical morbidity. The purpose of this study was to compare the technical feasibility, safety, and oncological efficacy of laparoscopic LPLN dissection (LPLD) following total mesorectal excision (TME) with open LPLD for locally advanced low rectal cancer (LALRC). METHODS Between January 2010 and December 2016, consecutive patients with LALRC and swollen LPLNs who underwent laparoscopic or open TME with LPLD at our institution were enrolled in this retrospective observational study. Data regarding patient demographics, perioperative characteristics, and oncological outcomes were analyzed and compared. RESULTS A total of 64 patients met the inclusion criteria. Thirty-four patients underwent open procedure, and 30 underwent laparoscopic procedure. The mean blood loss volume was significantly less in the laparoscopic group than in the open group (165 vs. 422 mL; P = 0.012). The mean operative time was not significantly different between the laparoscopic and the open groups (354 ± 91 vs. 315 ± 78 min; P = 0.522). The overall postoperative complication rates were 30.0% and 35.3% for the laparoscopic and open groups (P = 0.428), respectively. Postoperative urinary retention was significantly less in the laparoscopic group than in the open group (14.7 vs. 0%; P = 0.036).The duration of postoperative hospital stay was significantly shorter in the laparoscopic group (8.5 ± 3.8 vs. 13.6 ± 6.5 days; P = 0.025). The numbers of harvested lymph nodes and positive resection margin rates showed no significant differences. Pathological LPLN metastases were confirmed in 10 patients (29.4%) in the open group and 11 (36.7%) in the laparoscopic group (P = 0.537). The median follow-up duration was 41.5 months (range 3-98). The laparoscopic and open groups also showed a similar 3-year overall survival rate (88.2% vs. 85.3%; P = 0.577), relapse-free survival rate (73.3% vs. 67.6%; P = 0.889), and local recurrence rate (3.3 vs. 5.9%; P = 0.653). CONCLUSIONS Laparoscopic TME with LPLD is technically feasible and safe in selected patients with LALRC and is associated with similar oncological outcomes as open approach.

Abstract
BACKGROUND To compare outcomes of total mesorectal excision with or without lateral pelvic lymph node dissection for the treatment of rectal cancer. METHODS The electronic data sources were explored to capture all studies comparing total mesorectal excision with and without lateral pelvic lymph node dissection in patients undergoing operation for rectal cancer. Random effects modelling was utilized for the analyses. The uncertainties associated with varying follow-up periods among the included studies were resolved by analysis of time-to-event outcomes. RESULTS Eighteen comparative studies enrolling 6,133 patients were eligible. No difference was found between the 2 groups in terms of overall survival (hazard ratio: 0.92, 95% confidence interval 0.77-1.10, P = .36, I2 = 67%), overall survival at maximum follow-up (odds ratio: 1.02, 95% confidence interval 0.83-1.25, P = .86, I2 = 22%), 5-year overall survival (odds ratio: 1.01, 95% confidence interval 0.78-1.30, P = .94, I2 = 50%), disease-free survival (hazard ratio: 1.25, 95% confidence interval 0.87-1.82, P = .23, I2 = 74%), disease-free survival at maximum follow-up (odds ratio 1.07, 95% confidence interval 0.88-1.31, P = .50, I2 = 0%), 5-year disease-free survival (odds ratio: 1.07, 95% confidence interval 0.86-1.32, P = .54, I2 = 0%), local recurrence (odds ratio: 1.01, 95% confidence interval 0.72-1.42, P = .97, I2 = 34%), distant recurrence (odds ratio: 0.96, 95% confidence interval 0.62-1.46, P = .84, I2 = 18%), and total recurrence (odds ratio: 0.97, 95% confidence interval 0.72-1.29, P = .82, I2 = 0%). Total mesorectal excision with lateral pelvic lymph node dissection resulted in longer operative time (mean difference: 116.02, 95% confidence interval 89.20-142.83, P < .00001, I2 = 68%) and higher risks of postoperative complications (odds ratio: 1.59, 95% confidence interval 1.14-2.24, P = .007, I2 = 0%), urinary dysfunction (odds ratio: 6.66, 95% confidence interval 3.31-13.39, P < .00001, I2 = 23%), and sexual dysfunction (odds ratio: 9.67, 95% confidence interval 2.38-39.26, P = .002; I2 = 51%). The results remained consistent through separate analyses for randomized trials, observational studies, and patients with or without neoadjuvant chemoradiotherapy. CONCLUSION The available evidence suggests that lateral pelvic lymph node dissection results in greater postoperative morbidity, urinary dysfunction, and sexual dysfunction without improving recurrence and survival. Further evidence is needed from randomized controlled trials to enable experts in the nerve-sparing surgical experiences and neoadjuvant therapy experience to advise on the best treatment strategies for the management of rectal cancer patients including those with possible positive nodes on pretreatment imaging.

Abstract
BACKGROUND Acquiring appropriate laparoscopic technique is necessary to safely perform laparoscopic surgery. The Endoscopic Surgical Skill Qualification System of the Japanese Society of Endoscopic Surgery, which was established to improve the quality of laparoscopic surgery in Japan, provides training to become an expert laparoscopic surgeon. In this study, we describe our educational system, in a Japanese highest volume cancer center, and evaluate the system according to the pass rate for the Endoscopic Surgical Skill Qualification System examination. METHODS We assessed 14 residents who trained for more than 2 years from 2012 to 2018 in our department. All teaching surgeons, qualified by the Endoscopic Surgical Skill Qualification System, participated in all surgeries as supervisors. For the first 3 months, trainees learned as the scopist, then as the first assistant for 3 months, and then by performing laparoscopic surgery as an operator during ileocecal resection or sigmoidectomy. Trainees apply for this training in their second year of residency or later. All laparoscopic procedures in our department are standardized in detail. RESULTS The cumulative pass rate was 75% (12/16), and 87% (12/14) of the trainees eventually passed, while the general pass rate was approximately 30%. On average, those who passed in their second or third year had experienced 94 procedures as the surgeon, 177 as the first assistant, and 199 as the scopist. The number of laparoscopic procedures and the learning curves did not differ between successful and failed applicants. CONCLUSIONS Through our educational system, residents successfully acquired laparoscopic skills with a much higher pass rate in the Endoscopic Surgical Skill Qualification System examination than the general standard. Laparoscopic practice under supervision by experienced surgeons with standardized procedures and accurate understanding of the relevant anatomy is very helpful to achieving appropriate laparoscopic technique.

Abstract
There has historically been a significant divide in the approach to the management of lateral pelvic lymph nodes in patients with rectal cancer. These differing paradigms have developed based upon competing priorities. In the West, the circumferential resection margin has been the main focus because it is a strong predictor of local recurrence, distal recurrence, and survival. This approach was supplemented by radiation and chemotherapy to treat the lateral pelvic lymph nodes and micrometastatic disease. In the East, lateral pelvic lymph nodes are considered to be locoregional; thus, surgical treatment has traditionally included routine dissection of this compartment for low rectal cancers without the use of neoadjuvant chemoradiotherapy. However, neither approach has adequately addressed the important issue of lateral compartment recurrence in patients with clinically evident lateral pelvic lymph node metastasis. The aims of the review were to present the recent key studies and evolution of lateral pelvic lymph node management in locally advanced rectal cancer and secondly to propose a management strategy for the lateral compartment based on the current evidence.

Abstract
OBJECTIVE Our study is the first meta-analysis to compare total mesorectal excision (TME) plus lateral lymph node dissection (LLND) with TME on rectal cancer patients regarding outcomes including overall survival, disease-free survival, local recurrence, complications, urinary dysfunction, and sexual dysfunction. METHODS PubMed, Embase, and Cochrane library were searched for publications up to October 2019. Two investigators independently screened the studies for eligibility and extracted specific data. Relevant data were analyzed by Review Manager version 5.3. RESULTS Patients in TME + LLND group suffered more complications (OR = 1.48, 95% CI [1.07, 2.03], P = 0.02) compared with TME group; no significant difference was observed in overall survival (HR = 1.11, 95% CI [0.77, 1.61], P = 0.57), disease-free survival (HR = 1.05, 95% CI [0.85, 1.30], P = 0.64), local recurrence (OR = 0.93, 95% CI [0.56, 1.54], P = 0.78), and urinary dysfunction (OR = 1.60, 95% CI [0.66, 3.87], P = 0.3). CONCLUSION TME + LLND may cause more complications compared with TME on rectal cancer patients. However, the definite conclusion still requires more researches.

Abstract
BACKGROUND Lateral pelvic lymph node (LLN) metastasis (LLNM) occur in up to 28% of patients with low rectal tumours. While prophylactic lateral pelvic lymph node dissection (LLND) has been abandoned by most western institutions in the era of neoadjuvant chemoradiation therapy (CRT), the role of selective LLND in patients with enlarged LLN on pre-CRT imaging remains unclear. Some studies have shown improved survival and recurrence outcomes when LLNs show “response” to CRT. However, no management algorithm exists to differentiate treatment for “responders” vs “non-responders”.
AIM To determine if selective LLND in patients with enlarged LLNs results in improved survival and recurrence outcomes.
METHODS A systemic search of PubMed and Embase databases for studies reporting on patients with synchronous radiologically suspicious LLNM (s-LLNM) in rectal cancer receiving preoperative-CRT was performed.
RESULTS Fifteen retrospective, single-centre studies were included. 793 patients with s-LLNM were evaluated: 456 underwent TME while 337 underwent TME with LLND post-CRT. In the TME group, local recurrence (LR) rates range from 12.5% to 36%. Five-year disease free survival (DFS) was 42% to 75%. In the TME with LLND group, LR rates were 0% to 6%. Five years DFS was 41.2% to 100%. Radiological response was seen in 58%. Pathologically positive LLN was found in up to 94% of non-responders vs 0% to 20% in responders. Young age, low tumour location and radiological non-response were associated with final positive LLNM and lowered DFS.
CONCLUSION LLND is associated with local control in patients with s-LLNM. It can be performed in radiological non-responders given a large majority represent true LLNM. Its role in radiological responders should be considered in selected high risk patients.

What is the role of lateral lymph node dissection in rectal cancer patients with clinically suspected lateral lymph node metastasis after preoperative chemoradiotherapy? A meta-analysis and systematic review. Cancer Med 2020; 9:4477-4489.

Abstract
BACKGROUND Local lateral recurrence (LLR) in rectal cancer is increasingly becoming a significant clinical issue. Preoperative neoadjuvant chemoradiotherapy (nCRT) and lateral lymph node dissection (LLND)-when each approach is separately executed-cannot cure lateral lymph node metastasis (LLNM). Here, we performed a meta-analysis to evaluate the efficacy of nCRT plus total mesorectal excision (TME) vs TME plus LLND after nCRT for rectal cancer. METHODS Standard databases (PubMed, Embase, MEDLINE, Cochrane Library, and Web of Science) were searched to identify all relevant studies comparing nCRT+TME and nCRT+TME+LLND. Data in the included studies were extracted, and intraoperative outcomes, postoperative complications, and oncological outcomes were evaluated. RESULTS Eight studies representing 1,896 patients (1,461 nCRT+TME vs 435 nCRT+TME+LLND) were included. We found that for patients with clinically suspected LLNM, the incidence of pathological LLNM was 27.8%, even after nCRT. LLND after nCRT was significantly associated with lower LLR (P = .02). Additional LLND yielded a longer operative time (P < .01) and increased the risk of urinary dysfunction (P < .01). Concerning other outcomes, no significant differences were identified between the two groups. CONCLUSION This is the first meta-analysis and systematic review of studies comparing nCRT+TME and nCRT+TME+LLND for rectal cancer patients. Although increasing operative time and the risk of urinary dysfunction (which might be ameliorated by minimally invasive procedures), the pooled results support the use of LLND after nCRT and TME for reducing LLR in patients with clinically suspected LLNM and provide another treatment option for high-risk patients.

Abstract
In the era of neoadjuvant chemoradiotherapy/radiotherapy and total mesorectal excision, overall oncological outcomes after curative resection of rectal cancer are excellent, with local recurrence rates as low as 5–10%. However, lateral nodal disease is a major cause of local recurrence after neoadjuvant chemoradiotherapy/radiotherapy and total mesorectal excision. Patients with lateral nodal disease have a local recurrence rate of up to 30%. The oncological benefits of lateral pelvic lymph node dissection (LPLND) in reducing local recurrence, particularly in the lateral compartment, have been demonstrated. Although LPLND is not standard in Western countries, technical improvements in minimally invasive surgery have resulted in rapid technical standardization of this complicated procedure. The feasibility and short- and long-term outcomes of laparoscopic and robotic LPLND have been reported widely. A minimally invasive approach has the advantages of less bleeding and providing a better surgical view of the deep pelvic anatomy than an open approach. With precise autonomic nerve preservation, postoperative genitourinary dysfunction has been reported to be minimal. We review recent evidence on the management of lateral nodal disease in rectal cancer and technical improvements of LPLND, focusing on laparoscopic and robotic LPLND.

Abstract
Patients with low rectal cancer who have enlarged lateral pelvic lymph nodes are known to have a worse prognosis. There is however uncertainty over what constitutes a lateral pelvic lymph node of clinical significance. As the main modality for the detection of such lymph nodes is magnetic resonance imaging (MRI), characteristics of these lateral lymph nodes identified may have prognostic value and assist with guiding treatment. Options to manage such lateral lymph nodes includes neoadjuvant chemoradiotherapy as well as lateral lymph node dissection. Surgery is extensive and may lead to significant morbidity to the patient. This review article evaluates diagnostic and management strategies in patients with lateral pelvic lymph nodes in low rectal cancer.

Abstract
BACKGROUND Despite the use of neoadjuvant chemoradiation and total mesorectal excision for rectal cancer, lateral pelvic lymph node recurrence is still an important problem. OBJECTIVE This study aimed to determine the indication for lateral pelvic lymph node dissection in post neoadjuvant chemoradiation rectal cancer. DESIGN This is a retrospective analysis of a prospectively collected institutional database. SETTINGS This study was conducted at a tertiary care cancer center from January 2006 through December 2017. PATIENTS Patients who had rectal cancer with suspected lateral pelvic lymph node metastasis, who underwent total mesorectal excision with lateral pelvic lymph node dissection, were included. MAIN OUTCOME MEASURES The primary outcome measured was pathologic lateral pelvic lymph node positivity. INTERVENTIONS The associations between lateral pelvic lymph node size on post-neoadjuvant chemoradiation imaging and pathologic lateral pelvic lymph node positivity and recurrence outcomes were evaluated. RESULTS A total of 64 patients were analyzed. The mean lateral pelvic lymph node size before and after neoadjuvant chemoradiation was 12.6 ± 9.5 mm and 8.5 ± 5.4 mm. The minimum size of positive lateral pelvic lymph node was 5 mm on post neoadjuvant chemoradiation imaging. Among 13 (20.3%) patients who had a <5 mm lateral pelvic lymph node after neoadjuvant chemoradiation, none were pathologically positive. Among 51 (79.7%) patients who had a ≥5 mm lateral pelvic lymph node after neoadjuvant chemoradiation, 33 patients (64.7%) were pathologically positive. Five-year overall survival and disease-specific survival were higher in the histologic lateral pelvic lymph node negative group than in the lateral pelvic lymph node positive group (overall survival 79.6% vs 61.8%, p = 0.122; disease-specific survival 84.5% vs 66.2%, p= 0.088). After a median 39 months of follow-up, there were no patients in the <5 mm group who died of cancer. There were no lateral compartment recurrences in the entire cohort. LIMITATIONS Being a single-center retrospective study may limit generalizability. CONCLUSIONS Post-neoadjuvant chemoradiation lateral pelvic lymph node size ≥5 mm was strongly associated with pathologic positivity. No patients with size <5 mm had pathologically positive lymph nodes. Following lateral pelvic lymph node dissection, no patients with a positive lateral pelvic lymph node developed lateral compartment recurrence. Therefore, patients who have rectal cancer with clinical evidence of lateral pelvic lymph node metastasis and post-neoadjuvant chemoradiation lateral pelvic lymph node size ≥5 mm should be considered for lateral pelvic lymph node dissection at the time of total mesorectal excision.

OBJETIVO Determinar la indicación para la disección de los ganglios linfáticos pélvicos laterales en el cáncer rectal post quimiorradiación neoadyuvante. DISEÑO:: Análisis retrospectivo de la base de datos institucional prospectivamente recopilada. ESCENARIO Centro de cáncer de atención terciaria, de enero de 2006 hasta diciembre de 2017. PACIENTES Pacientes con cáncer de recto con sospecha de metástasis en los ganglios linfáticos pélvicos laterales, que se sometieron a escisión total mesorectal con disección de los ganglios linfáticos pélvicos laterales. PRINCIPALES MEDIDAS DE RESULTADOS Positividad de ganglios linfáticos pélvicos laterales en histopatología. INTERVENCIONES Se evaluaron las asociaciones entre el tamaño de los ganglios linfáticos pélvicos laterales en imagenología postquimiorradiación neoadyuvante y la positividad y recurrencia en los ganglios linfáticos pélvicos laterales en histopatología. RESULTADOS Se analizaron un total de 64 pacientes. La media del tamaño de los ganglios linfáticos pélvicos laterales antes y después de la quimiorradiación neoadyuvante fue de 12.6 ± 9.5 mm y 8.5 ± 5.4 mm, respectivamente. El tamaño mínimo de los ganglios linfáticos pélvicos laterales positivos fue de 5 mm en las imágenes postquimiorradiación neoadyuvante. Entre 13 (20.3%) pacientes que tenían <5 mm de ganglio linfático lateral pélvico después de la quimiorradiación neoadyuvante; ninguno fue positivo en histopatología. Entre 51 (79.7%) pacientes con ganglio linfático pélvico lateral ≥ 5 mm después de la quimiorradiación neoadyuvante; 33 pacientes (64.7%) fueron positivos en histopatología. La supervivencia general a 5 años y la supervivencia específica de la enfermedad fueron mayores en el grupo histológico de ganglio linfático pélvico lateral negativo que en el grupo de ganglio linfático pélvico lateral positivo (Supervivencia general 79.6% vs 61.8%, p = 0.122; Supervivencia específica de la enfermedad 84.5% vs 66.2%, p = 0.088). Después de una mediana de seguimiento de 39 meses, no hubo pacientes en el grupo de <5 mm que hayan fallecido por cáncer. No hubo recurrencias en el compartimento lateral en toda la cohorte. LIMITACIONES Al ser un estudio retrospectivo en un solo centro puede limitar la generalización. CONCLUSIONES El tamaño de los ganglios linfáticos pélvicos laterales postquimiorradiación neoadyuvante ≥ 5 mm se asoció fuertemente con la positividad histopatológica. Ningún paciente con tamaño <5 mm tuvo ganglios linfáticos histopatológicamente positivos. Después de la disección de los ganglios linfáticos pélvicos laterales, ningún paciente con ganglios linfáticos pélvicos laterales positivos desarrolló recurrencia del compartimiento lateral. Por lo tanto, los pacientes con cáncer rectal con evidencia clínica de metástasis en los ganglios linfáticos pélvicos laterales y tamaño de ganglios linfáticos pélvicos laterales postquimiorradiación neoadyuvante ≥ 5 mm deben considerarse para disección de los ganglios linfáticos pélvicos laterales en el momento de la escisión total de mesorrecto.

Abstract
BACKGROUND This study aimed to evaluate the technical feasibility, safety and oncological outcomes of laparoscopic total mesorectal excision (TME) with selective lateral lymph node (LLN) dissection (sLLND) in patients with locally advanced rectal cancer (LARC) and clinically suspected swollen LLNs treated with preoperative neoadjuvant chemoradiotherapy (nCRT). METHODS Consecutive patients with LARC and swollen LLNs who underwent laparoscopic TME and sLLND following nCRT between October 2012 and October 2018 were reviewed from the prospectively collected database. Patient demographics, operation safety, perioperative complications and oncological outcomes were analysed. RESULTS A total of 43 patients were identified. All procedures were completed under laparoscopy without conversion to open surgery. The median operation time was 313 min (range 170-570 min). The median blood loss was 80 mL (range 30-450 mL). The median number of LLNs harvested was 11 (range 1-29). LLN metastasis was found in 12 patients (27.9%). Major post-operative complications were found in four patients (9.3%). The median hospital stay was 7 days (range 4-27 days). The median time to tolerance to liquid food was 72 h (range 36-120 h). The post-operative 30-day mortality rate was 0%. Over the median follow-up of 24 months, no lateral pelvic recurrence developed. For the whole group of patients, the 2-year cumulative overall survival and disease-free survival were 90.5% and 78.1%, respectively. CONCLUSION With the advantages of a minimally invasive approach, laparoscopic TME and sLLND following preoperative nCRT in patients with LARC and swollen LLNs is safe and feasible. This procedure provides acceptable perioperative and oncological outcomes.

BACKGROUND As one effective treatment for lateral pelvic lymph node (LPLN) metastasis (LPNM), laparoscopic LPLN dissection (LPND) is limited due to the complicated anatomy of the pelvic sidewall and various complications after surgery. With regard to improving the accuracy and completeness of LPND as well as safety, we tried an innovative method using indocyanine green (ICG) visualized with a near-infrared (NIR) camera system to guide the detection of LPLNs in patients with middle-low rectal cancer.
AIM To investigate whether ICG-enhanced NIR fluorescence-guided imaging is a better technique for LPND in patients with rectal cancer.
METHODS A total of 42 middle-low rectal cancer patients with clinical LPNM who underwent total mesorectal excision (TME) and LPND between October 2017 and March 2019 at our institution were assessed and divided into an ICG group and a non-ICG group. Clinical characteristics, operative outcomes, pathological outcomes, and postoperative complication information were compared and analysed between the two groups.
RESULTS Compared to the non-ICG group, the ICG group had significantly lower intraoperative blood loss (55.8 ± 37.5 mL vs 108.0 ± 52.7 mL, P = 0.003) and a significantly larger number of LPLNs harvested (11.5 ± 5.9 vs 7.1 ± 4.8, P = 0.017). The LPLNs of two patients in the non-IVG group were residual during LPND. In addition, no significant difference was found in terms of LPND, LPNM, operative time, conversion to laparotomy, preoperative complication, or hospital stay (P > 0.05).
CONCLUSION ICG-enhanced NIR fluorescence-guided imaging could be a feasible and convenient technique to guide LPND because it could bring specific advantages regarding the accuracy and completeness of surgery as well as safety.

Risk factors and prognostic significance of lateral pelvic lymph node metastasis in advanced rectal cancer. Int J Clin Oncol 2019; 25:110-117. [PMID: 31407167 DOI: 10.1007/s10147-019-01523-w] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2019] [Accepted: 08/04/2019] [Indexed: 12/30/2022]
Abstract
BACKGROUND The aim of this study was to elucidate the risk factors for and prognostic value of lateral pelvic lymph node (LPLN) metastasis in advanced rectal cancer patients, including those with stage IV disease. METHODS The treatment outcomes of 78 patients with advanced rectal cancer, the lower margin of which was located at or below the peritoneal reflection, who underwent curative-intent surgery with bilateral LPLN dissection from 2005 to 2018 were retrospectively analyzed. RESULTS In total, 78 rectal cancer patients, including 13 patients with stage IV tumors, 9 patients (11.5%) had LPLN metastasis. A multivariate analysis to identify preoperative clinical factors associated with LPLN metastasis showed that tumor location (below the peritoneal reflection: Rb), LPLN metastasis on preoperative imaging and distant metastasis were independent predictors of LPLN metastasis. In addition, metastasis at the regional lymph nodes in the mesorectum was significantly associated with LPLN metastasis. Both the disease-free survival (DFS) and cancer-specific survival (CSS) of patients with LPLN metastasis were significantly worse in comparison to patients without LPLN metastasis, and the CSS of stage IV patients with LPLN metastasis was significantly worse in comparison to stage IV patients without LPLN metastasis. CONCLUSIONS Tumor location (Rb), LPLN metastasis on preoperative imaging and distant metastasis were risk factors for LPLN metastasis. The prognosis of rectal cancer patients with LPLN metastasis is poor. There may not be the indication of LPLN dissection in stage IV lower rectal cancer except cases having complaints due to LPLN metastasis.

Abstract
Background There is a lack of large studies focusing on the prognostic significance of lateral lymph node (LLN) metastasis following LLN dissection (LLND) in rectal cancer. The aim of this study was to evaluate the prognostic impact of LLN metastases on survival of patients with advanced low rectal cancer. Methods Consecutive patients with locally advanced, but not metastatic, extraperitoneal rectal cancer treated with neoadjuvant (chemo)radiotherapy plus total mesorectal excision between 2004 and 2015 were included in the study. LLND was performed when pretreatment imaging documented enlarged LLNs (7 mm or greater in size). Localization of nodal metastases and long‐term outcomes were analysed. Kaplan–Meier analysis was used to compare the survival of patients with ypN0 disease with that of patients with mesorectal ypN+/LLN− status and patients with positive LLNs. The Cox proportional hazards model was used to evaluate predictors of disease‐free survival (DFS) and local recurrence. Results A total of 613 patients were included in the study; LLND was performed in 212 patients (34·6 per cent) and 57 (9·3 per cent) had LLN metastasis. Patients with LLN metastasis had improved DFS and local recurrence cumulative incidence rates compared with patients with mesorectal ypN2+/LLN− disease (DFS: P = 0·014; local recurrence: P = 0·006). Although the DFS rate of patients with LLN metastasis was worse than that of patients with ypN0 disease (P < 0·001), the cumulative incidence of local recurrence was similar (P = 0·491). In multivariable analysis, residual LLN metastasis was not an independent predictor of worse DFS or local recurrence. Conclusion LLN metastasis is not an independent predictor of local recurrence or survival. Survival of patients presenting with LLN metastasis after (chemo)radiotherapy was intermediate between that of patients with ypN0 status and those with mesorectal ypN2 positivity.

Abstract
Here we report a case of advanced rectal and prostate cancer with synchronous lateral lymph node (LLN) metastases that was treated with laparoscopic surgery. A 71-year-old man presented with fecal occult blood and was diagnosed with rectal cancer. A metastatic right LLN was suspected after CT examination of a 19-mm lymph node (proximal internal iliac artery region) and a 13-mm lymph node (distal internal iliac artery region) in the right lateral region. We planned neoadjuvant chemotherapy to suppress local and distant recurrence. This treatment decreased the size of the primary rectal tumor. We performed laparoscopic abdominoperineal resection and right LLN dissection. The histopathological diagnosis was LLN metastases from the rectal and prostate cancers. It is rare for synchronous metastases from rectal and prostate cancers to be observed in the LLN. It may be difficult to determine an appropriate treatment strategy in cases like this.

Abstract
OBJECTIVE This study aimed to assess the learning curve of robotic rectal surgery, a procedure that has gained increasing focus in recent years because it is expected that the advanced devices used in this approach provide advantages resulting in a shorter learning curve than that of laparoscopic surgery. However, no studies have assessed the learning curve of robotic rectal surgery, especially when lateral lymph node dissection is required. DESIGN This was a nonrandomized, retrospective study from a single institution. SETTING All consecutive patients who underwent robotic rectal or sigmoid colon surgery by a single surgeon between February 2012 and July 2016 in the University of Tokyo Hospital were enrolled. The learning curve for console time was assessed using a cumulative sum analysis and multiple linear regression analysis. PARTICIPANTS A total of 131 consecutive patients underwent robotic rectal or sigmoid colon surgery performed by a single experienced surgeon. Of these, 41 patients received lateral lymph node dissection. RESULTS A cumulative sum plot for console time demonstrated that the learning period could be divided into 3 phases: Phase I, Cases 1 to 19; Phase II, Cases 20 to 78; and Phase III, Cases 79 to 131. Multiple linear regression analysis indicated that console time decreased significantly from one phase to another (Phase I-II, Δconsole time 83.0 minutes; Phase II-III, Δconsole time 40.1 minutes). Other factors affecting console time included body mass index, operative procedure, and lateral lymph node dissection, but not neoadjuvant therapy (such as chemoradiotherapy) or depth of invasion. Lateral lymph node dissection required an additional 138.4 minutes. CONCLUSIONS Our findings suggest that the first phase of the learning curve consists of the first 19 cases, which seems sufficient to master the manipulation of robotic arms and to understand spatial relationships unique to the robotic procedure.

Abstract
INTRODUCTION Laparoscopic lateral pelvic lymph node dissection (LPLD) is technically challenging because of the complicated anatomy of the pelvic wall. To overcome this difficulty, we introduced preoperative 3-D simulation. The aim of the study is to investigate the usefulness of preoperative 3-D simulation for the safe conduct of laparoscopic LPLD for rectal cancer. METHODS After undergoing colonoscopy, patients were brought to the radiology suite where multi-detector row CT was performed. Three-dimensional images were constructed at a workstation and showed branches of the iliac artery and vein, ureter, urinary bladder, and enlarged lymph nodes. All members of the surgical team participated in preoperative simulation using the 3-D images. RESULTS A total of 10 patients with advanced lower rectal cancer and enlarged lateral pelvic lymph nodes underwent laparoscopic unilateral LPLD after total mesorectal excision, tumor-specific mesorectal excision, or total proctocolectomy. Four of the 10 patients (40%) had variations in pelvic vascular anatomy. The median operative time for unilateral LPLD was 91 min (range, 66-142 min) and gradually declined, suggesting a good learning curve. The median number of lateral pelvic lymph nodes harvested was nine (range, 3-16). The median estimated blood loss was 13 mL (range, 10-160 mL). No conversion to open surgery or intraoperative complications occurred. No patient had major postoperative complications. CONCLUSION Preoperative 3-D simulation may be useful for the safe conduct of laparoscopic LPLD, especially for surgeons with limited prior experience.

Abstract
The lateral lymph node dissection (LLND) is still a subject of great debate as to the appropriate treatment for patients with mid to low advanced rectal cancer. The guidelines of the Japanese Society for Cancer of the Colon and Rectum recommend a LLND for patients with T3/4 rectal cancer below the peritoneal reflection. However, in most Western countries, a routine LLND is not recommended unless a node or nodes are clinically suspicious for metastasis. Even after preoperative chemoradiotherapy (CRT), an 8% to 12% lateral pelvic recurrence was noted. The size of the lateral lymph node and responsiveness to preoperative CRT should be the main factors for selecting appropriate patients to undergo a LLND. In addition, from the recent literature, a laparoscopic LLND is safe and oncologically feasible and might have some advantages in short-term outcomes.

Abstract
Total mesorectal excision or mesorectal excision with lateral lymph node dissection (LLND) is a standard treatment for locally advanced lower rectal cancer in Japan. Although laparoscopic LLND for rectal cancer is technically complex and challenging, previous studies have demonstrated its feasibility, and the procedure is gradually becoming more common. With this increased use, the incidence of new complications specific to laparoscopic LLND is likely to increase, and a greater awareness of these complications is required. Here we report two cases of internal hernia of the small bowel through an orifice of the vesicohypogastric fascia below the superior vesical artery after laparoscopic LLND. There are six previous reports of internal hernia underneath the pelvic blood vessel after pelvic lymph node dissection for urological or gynecological malignancies, but our cases are the first two that occurred after LLND for rectal cancer. Almost all cases, including our two cases, occurred after laparoscopic surgery and required resection of an incarcerated small bowel. Therefore, the incidence of this complication is likely to increase as the number of cases treated with laparoscopic LLND increases. Our cases show that it is important to perform an emergency operation promptly instead of conservative treatment.

Med Sci Monit 2018; 24:3966-3977.

Abstract
BACKGROUND The feasibility of additional dissection of the lateral pelvic lymph nodes (LPLNs) in patients undergoing total mesorectal excision (TME) combined with neoadjuvant chemotherapy (NAC) for locally advanced rectal cancer (LARC) is controversial. The use of laparoscopic surgery is also debated. In the present study, we evaluated the utility of laparoscopic dissection of LPLNs during TME for patients with LARC and metastatic LPLNs after NAC, based on our experience with 19 cases. MATERIAL AND METHODS Twenty-five patients with LARC with swollen LPLNs who underwent laparoscopic TME and LPLN dissection were enrolled in this pilot study. The patients were divided into 2 groups: those patients with NAC (n=19) and without NAC (n=6). Our NAC regimen involved 4 to 6 courses of FOLFOX plus panitumumab, cetuximab, or bevacizumab. RESULTS The operative duration was significantly longer in the NAC group than in the non-NAC group (648 vs. 558 minutes, respectively; P=0.022). The rate of major complications, defined as grade ≥3 according to the Clavien-Dindo classification, was similar between the 2 groups (15.8% vs. 33.3%, respectively; P=0.4016). No conversion to conventional laparotomy occurred in either group. In the NAC group, a histopathological complete response was obtained in 2 patients (10.5%), and a nearly complete response (Tis N0 M0) was observed in one patient (5.3%). Although the operation time was prolonged in the NAC group, the other perioperative factors showed no differences between the 2 groups. CONCLUSIONS Laparoscopic LPLN dissection is feasible in patients with LARC and clinically swollen LPLNs, even after NAC.
