Abstract
Objectives A total mesenteric excision (TME) with lateral pelvic lymph node dissection (LLND) is the standard treatment for advanced low rectal cancer in Japan. Recently, neoadjuvant (chemo)radiotherapy (n(C)RT) has been used with LLND to improve outcomes at multiple Japanese institutes. This study evaluates the benefits of adding nCRT to TME with LLND. Methods Seventy-two consecutive patients who underwent TME and LLND with or without nCRT between 2006-2019 to treat advanced low rectal cancer were retrospectively reviewed. The clinicopathological data were compared and the risk factors for local recurrence were evaluated. Results Fifty-seven patients (79.1%) underwent TME and LLND with nCRT, and 15 patients (20.9%) without nCRT. There was no significant difference in the clinicopathological characteristics except the clinical T stage. The occurrence of postoperative complications was statistically insignificant. The 5-year local recurrence rate of patients with nCRT was significantly lower than those without (4.0% versus 26.6%, in all patients, p=0.002). Multivariate analysis revealed that the absence of nCRT was an independent risk factor for local recurrences in patients who underwent TME with LLND (hazard ratio: 6.04, p=0.04). Conclusions The administration of nCRT prevented local recurrences more effectively in patients with advanced low rectal cancer who underwent TME with LLND.

Abstract
Purpose Local recurrence (LR) is the main cause of treatment failure in locally advanced lower rectal cancer (LALRC). This study evaluated the preoperative risk factors for LR in patients with LALRC to improve the therapeutic strategies. Patients and Methods LALRC patients who underwent total mesorectal excision (TME) with lateral pelvic lymph node (LPN) dissection (LPND) from January 2012 to December 2019 were reviewed. The log-rank test was used to assess local recurrence-free survival (LRFS), and multivariate Cox regression was used to identify the prognostic risk factors for LRFS. Follow-up imaging data were used to classify LR according to the location. Results Overall, 376 patients were enrolled, and 8.8% (n=33) of these patients developed LR after surgery. Multivariate analysis identified positive clinical circumferential resection margin (cCRM) as an independent prognostic factor for LRFS (HR: 4.94; 95% CI, 1.75-13.94; P=0.003). The most common sites for LR were the pelvic plexus and internal iliac area (PIA) (54.5%), followed by the central pelvic area (CPA) (39.4%) and obturator area (OA) (6.1%). Following a subgroup analysis, LR in the OA was not associated with positive cCRM. Patients treated with upfront surgery (n=35, 14.1%) had a lower cCRM positive rate when compared with patients treated with neoadjuvant chemoradiotherapy (nCRT) (n=12, 23.5%). However, the LR rate in the nCRT group was still lower (n=28, 36.4%) than that in the upfront surgery group (n=35, 14.%). Among patients with positive cCRM, the LR rate in patients with nCRT remained low (n=3, 10.7%). Conclusion Positive cCRM is an independent risk factor for LR after TME plus LPND in LALRC patients. LPND is effective and adequate for local control within the OA regardless of cCRM status. However, for LALRC patients with positive cCRM, nCRT should be considered before LPND to further reduce LR in the PIA and CPA.

Abstract
INTRODUCTION The role of robotic lateral pelvic lymph node dissection (LPLND) for lateral pelvic nodal disease (LPND) in rectal cancer has yet to be investigated in the Western hemisphere. This study aims to investigate the safety and feasibility of robotic LPLND by utilising a well-established totally robotic TME protocol. METHODS We conducted a retrospective study on 17 consecutive patients who underwent robotic LPLND for LPND ± TME for rectal cancer between 2015 and 2021. A single docking totally robotic approach from the left hip with full splenic mobilisation was performed using the X/Xi da Vinci platform. All patients underwent a tri-compartmental robotic en bloc excision of LPND with preservation of the obturator nerve and pelvic nerve plexus, leaving a well-skeletonised internal iliac vessel and its branches. RESULTS The median operative time was 280 min, which was 40 min longer than our standard robotic TME. The median BMI was 26, and there were no conversions. The median inpatient stay was 7 days with no Clavien-Dindo > 3 complications. One patient (6%) developed local recurrence and metastatic disease within 5 months. The proportion of histologically confirmed LPND was 41%, of which 94% were well to moderately differentiated adenocarcinoma. Median pre-operative lateral pelvic node size was significantly higher in positive nodes (14 mm vs. 8 mm (p = 0.01)). All patients had clear resection margins on histology. DISCUSSION Robotic LPLND is safe and feasible with good peri-operative and short-term outcomes, with the ergonomic advantages of a robotic TME docking protocol readily transferrable in LPLND.

Abstract
Lateral pelvic lymph node dissection (LPND) is a technically demanding procedure. This study aimed to compare the short-term outcomes of laparoscopic and robotic LPNDs. This multi-institutional retrospective study included 108 consecutive patients who underwent laparoscopic or robotic total mesorectal excision with LPND for locally advanced rectal cancer. There were 74 patients in the laparoscopic and 34 in the robotic groups. The median operation time was longer in the robotic group than in the laparoscopic group (353 vs. 275 min, p < 0.001). No patients underwent conversion to open surgery in either group. Pathological LPN metastases were observed in 24 and 8 patients in the laparoscopic and robotic groups, respectively (p = 0.347). Although the number of harvested mesorectal lymph nodes was similar (15.5 vs. 15.0, p = 0.968), the number of harvested LPNs was higher in the robotic than in the laparoscopic group (7.0 vs. 5.0, p = 0.004). Postoperative complications and length of hospital stay were similar (robotic vs. laparoscopic, 35.3% and 7 days vs. 37.8% and 7 days, respectively). Both laparoscopic and robotic LPND are safe and feasible for locally advanced rectal cancers, but robotic LPND showed more harvested lateral lymph node than laparoscopic LPND.

Abstract
AIM The standard strategy for clinical T3 rectal cancer without enlarged lateral lymph nodes is preoperative chemoradiotherapy (CRT) followed by total mesorectal excision (TME) in Western countries and TME with bilateral lateral pelvic lymph node dissection (LPLND) in Japan. This study compared surgical, pathological and oncological results of these two strategies. METHOD Patients who underwent preoperative CRT followed by TME in France (CRT + TME group) and those who underwent TME with LPLND in Japan (TME + LPLND group) for clinical T3 rectal adenocarcinoma without enlarged lateral lymph nodes from 2010 to 2016 were retrospectively analysed. RESULTS In total, 439 patients were included in this study. The estimated local recurrence rate (LRR), disease-free survival and overall survival at 5 years post-surgery was 4.9%, 71% and 82% in the CRT + TME group, and 8.6%, 75% and 90% in the TME + LPLND group, respectively. Lateral LRR versus non-lateral LRR was 0.5% versus 4.2% in the CRT + TME group and 1.8% versus 6.2% in the TME + LPLND group. Obturator nerve injury and isolated pelvic abscess were shown only in the TME + LPLND group. Urinary complications were more frequent in the TME + LPLND group than in the CRT + TME group. CONCLUSION Disease-free survival was not significantly different after TME with LPLND and after CRT followed by TME. LRR was not significantly different after both strategies; however, there was a trend for higher LRR after TME with LPLND than after CRT followed by TME. Obturator nerve injury, isolated lateral pelvic abscess and urinary complications should be noted when TME with LPLND is applied.

Abstract
Objectives The present study aimed to investigate the clinical relevance of lateral pelvic lymph node dissection (LPLND) in low rectal cancer without preoperative treatment, with a focus on the presence of LPLN enlargement in preoperative imaging. Methods Consecutive patients with cT3 to T4 low rectal cancer who underwent mesorectal excision and LPLND without preoperative treatment between 2007 and 2018 at a single dedicated cancer center were included. LPLN short-axis diameter (SAD) measured using preoperative multi-detector row computed tomography (MDCT) was evaluated retrospectively. Results A total of 195 consecutive patients were analyzed. Overall, 101 (51.8%) and 94 (48.2%) patients had visible and no visible LPLNs in preoperative imaging, including 56 (28.7%), 28 (14.4%), and 17 (8.7%) patients had SADs of <5 mm, 5-7 mm, and ≥7 mm, respectively. Incidence of pathologically confirmed LPLN metastasis were 18.1%, 21.4%, 28.6%, and 52.9%, respectively. Overall, thirteen (6.7%) patients developed local recurrence (LR), including one patient who developed lateral recurrence, yielding a 5-year cumulative risk for LR of 7.4%. Five-year RFS and OS for all patients were 69.7% and 85.7%, respectively. No differences were observed in the cumulative risk for LR and OS between any pairs of groups. Conclusions No significant difference was observed in the cumulative risk for LR and OS regardless of LPLN SAD, implying the good impact of LPLND on the prevention of lateral recurrence, as well as the difficulty of predicting LPLN metastasis using only LPLN SAD in preoperative imaging.

Abstract
BACKGROUND The management of lateral pelvic lymph nodes for rectal cancer is a topical and controversial issue. The aim of this study was to assess the relationship between lateral pelvic lymph node features on magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) with oncological outcomes in patients with rectal cancer. METHODS A retrospective analysis of 284 patients with primary locally advanced rectal cancer treated with neoadjuvant therapy and surgical resection with curative intent between January 2003 and Dec 2018 was undertaken. From this study population, a select cohort of 77 patients with abnormal lateral pelvic lymph nodes on preoperative imaging had imaging re-analysed by radiologists blinded to clinical outcomes. Pre and post neoadjuvant therapy MRI and PET-CT lateral pelvic lymph node features were correlated with oncological outcomes. RESULTS A lateral pelvic lymph node short axis size ≥5 mm on post neoadjuvant therapy MRI was a significant predictor of worse 3-year local recurrence free survival (HR 8.35, P = 0.001). Lateral pelvic lymph node avidity on post neoadjuvant therapy PET-CT was a significant predictor of worse 3-year distant recurrence free survival (HR 5.62, P = 0.001). No correlation of oncological outcomes with overall survival was identified. CONCLUSION Lateral pelvic lymph node imaging features on post-neoadjuvant therapy MRI and PET-CT predicted those at risk of rectal cancer recurrence. Further studies are required to confirm these findings that suggest restaging MRI and PET-CT are complementary modalities for the preoperative assessment of lateral pelvic lymph nodes in rectal cancer.

Abstract
Tumour deposits (TDs), novel pathological entities, should be considered when estimating the regional and systemic spread of rectal carcinoma and formulating treatment strategies. In fact, TDs may have more severe prognostic impact than lymph node positivity or the lymph node ratio. The assessment of the presence of TDs can be performed only through accurate postoperative pathological examination; however, the detection of TDs is not part of any of the procedures currently used to assess preoperative or intraoperative staging. This review aims to analyse and discuss the impact of TDs on the oncological outcome of patients who undergo surgery for advanced low rectal carcinoma. No prospective study has evaluated the impact of lateral pelvic TDs on oncological outcomes following total mesorectal excision with lateral pelvic lymphadenectomy. Although adequate total mesorectal excision allows for the excision of intramesorectal TDs, lateral pelvic lymph node dissection cannot guarantee the removal of lateral pelvic TDs; moreover, it remains to be determined whether surgical excision of lateral pelvic TDs can impact long-term outcomes. However, the identification of lateral pelvic TDs strengthens the 'staging effect' and limits the 'therapeutic effect' of lateral pelvic lymphadenectomy, supporting the rationale for the use of neoadjuvant chemoradiotherapy for rectal cancer. When evaluating the oncological outcomes after total mesorectal excision with lateral pelvic lymphadenectomy, the impact of lateral pelvic TDs should be considered.

Abstract
AIM Lateral pelvic lymph node dissection (LPND) is a technically challenging procedure, and the safety and feasibility of laparoscopic LPND remains undetermined. Here, we compared the short- and long-term survival outcomes of laparoscopic LPND with those of open LPND. METHODS From January 2012 to December 2019, locally advanced middle-low rectal cancer patients with clinical evidence of lateral pelvic lymph node metastasis (LPNM) who underwent total mesorectal excision with LPND at three institutions were included. Propensity score matching was used to minimize selection bias. The short-term and oncological outcomes of open and laparoscopic LPND were compared. RESULTS Overall, 384 patients were enrolled into the study including 277 and 107 patients who underwent laparoscopic and open LPND, respectively. After matching, patients were stratified into laparoscopic (n = 100) and open (n = 100) LPND groups. Patients in the laparoscopic LPND group had a shorter operation time (255 vs. 300 min, p = 0.001), less intraoperative blood loss (50 vs. 300 ml, p < 0.001), lower incidence of postoperative complications (32.0% vs. 15.0%, p = 0.005), shorter postoperative hospital stay (8 vs. 14 days, p < 0.001), and excision of more lateral pelvic lymph nodes (9 vs. 7, p = 0.025) than those in the open LPND group. The 3-year overall survival (p = 0.581) and 3-year disease-free survival (p = 0.745) rates were similar between the groups, and LPNM was an independent predictor of survival. CONCLUSION Laparoscopic LPND is technically safe and feasible with favourable short-term results and similar oncological outcomes as open surgery in selected patients.

Abstract
OBJECTIVE Total mesorectal excision (TME) plus lateral pelvic lymph node (LPN) dissection (LPND) is a technically complex and challenging procedure with higher morbidity than TME alone. We aimed to investigate the risk factors for postoperative complications after TME + LPND, and the impact of complications on patient prognosis. METHODS A total of 387 rectal cancer patients with clinical LPN metastasis (LPNM) who underwent TME + LPND at three institutions affiliated with the Chinese Lateral Node Collaborative Group were included. Logistic regression models were used to identify the risk factors for post-surgical complications, and the log-rank test was used to compare the prognosis. Severe complications were described as grade III-V. RESULTS The incidence rates of overall complications and severe complications after TME + LPND were 15.2% (59/387) and 7.8% (30/387), respectively. Multivariate analysis showed that a duration of operation ≥260 min was an independent risk factor for both overall (odds ratio [OR] = 3.03, 95% confidence interval [CI] = 1.57-5.85, P = 0.001) and severe postoperative complications (OR = 2.67, 95% CI = 1.06-6.73, P = 0.037). The development of overall postoperative complications (P = 0.114) and severe postoperative complications (P = 0.298) had no significant impact on the overall survival. However, patients with overall complications (P = 0.015) or severe complications (P = 0.031) with a postoperative hospital stay >30 days had significantly an overall worse survival. CONCLUSION A surgical duration of ≥260 min is a significant risk factor for both overall and severe postoperative complications after TME + LPND for middle-low rectal cancer. Furthermore, the development of overall complications or severe complications that require a postoperative hospital stay >30 days significantly worsens the prognosis.

Abstract
BACKGROUND Global differences exist in managing lateral pelvic nodes in rectal cancer. Recent studies demonstrate improved local recurrence rates in patients undergoing lateral pelvic lymph node dissections (LPND) in addition to total mesorectal excision (TME) for advanced lower rectal cancer. This study aims to report on the safety and feasibility of the robotic approach in patients undergoing pelvic sidewall lymph node dissection or en-bloc sidewall resection for advanced lower rectal cancer. METHODS Patients who underwent an elective robotic pelvic sidewall lymph node dissection or en-bloc sidewall resection for locally advanced rectal cancer with suspicious lateral lymph nodes or pelvic side wall involvement between January 2018 and March 2021 were included. Demographic, clinical, perioperative and histopathological variables were recorded and analysed. RESULTS Eight patients (3 males) with a mean age of 55 (33-73) years and mean body mass index of 26.3 (20.7-30.0) kg/m2 were included. The median operative time and blood loss were 458.75 (360-540) min and 143.75 (100-300) mL, respectively. There were no conversions or intra-operative complications. There were three post-operative complications recorded (two ileus and one anastomotic leak which required an endoscopic washout in theatre and intravenous antibiotics thereafter). Median length of stay was 12.75 (7-23) days. All patients had an R0 resection, and the median lateral pelvic lymph node yield was 9.1 (6-14). CONCLUSION This series demonstrates the practicality and the safety of the robotic approach in the introduction of this technique for en-bloc resection or LPND in patients with locally advanced rectal cancer.

Abstract
AIM Direct-to-surgery rectal resection with lateral pelvic lymph node dissection (LPLND) is a treatment strategy commonly employed in Japan to improve oncological outcomes for rectal cancer. The aim of this study was to assess oncological outcomes in the literature for patients with low rectal cancer who underwent direct-to-surgery resection and LPLND compared with those who underwent total mesorectal excision (TME) alone. METHOD A literature search of Medline, Embase and PubMed databases was performed to identify relevant studies published between 1989 and 2020. The primary outcomes were 5-year overall survival (OS) and 5-year disease-free survival (DFS). The secondary outcomes were cancer recurrence (local, distant and total) and operative burden (operative time and blood loss). Pooled relative risk (RR) of oncological outcomes was performed using the DerSimonian-Laird method random-effect model. RESULTS Twenty-one studies fulfilled inclusion criteria, including 19 nonrandomized studies of interventions and two studies from one randomized controlled trial. No differences were observed in 5-year OS or 5-year DFS. Local recurrence in nonrandomized studies was worse in patients who underwent LPLND [RR 1.41 (95% CI 1.21-1.64, p < 0.001)], as was total recurrence [RR 1.44 (95% CI 1.25-1.67, p < 0.001)]. No differences were observed for distant recurrence. CONCLUSION In the published literature, direct-to-surgery resection with LPLND was associated with worse local and total recurrence. These predominantly nonrandomized data suggest that a nonselective approach to LPLND does not provide optimal management in radiotherapy-naïve patients with low rectal cancer. Further prospective randomized studies with a focus on patient selection are required.

Abstract
Objectives: The standard strategy for advanced rectal cancer (RC) is preoperative short-course radiotherapy (SCRT)/chemoradiotherapy (CRT) plus total mesorectal excision (TME) in Western countries; however, the survival benefit of adding chemotherapy to radiotherapy remains unclear. There is accumulating evidence that either SCRT/CRT or lateral pelvic lymph node dissection (LPND) alone may not be sufficient for local control of advanced RC. We herein retrospectively evaluated the clinical outcomes of patients who were treated by SCRT/CRT+TME+LPND, particularly focusing on the prognostic impact of lateral pelvic lymph node metastasis (LPNM). Methods: Patients diagnosed as having clinical Stage II and III lower RC who received SCRT/CRT+TME+LPND between 1999 and 2012 at our hospital were enrolled. Adverse events (AEs), surgery-related complications (SRC), and therapeutic effects were retrospectively analyzed. Results: Fifty cases (SCRT:25, CRT:25) were analyzed. No significant differences were observed in overall survival (OS), relapse-free survival (RFS), local recurrence (LR), AE, and SRC between the SCRT and CRT groups, although the pathological therapeutic effect was higher in the CRT group. The patients with LPNM showed significantly inferior 5-year OS and 5-year RFS than those without LPNM. Conclusions: There were no significant differences in OS, RFS, or LR between SCRT and CRT, although CRT had a significantly greater histological therapeutic effect. The prognosis of the pathological LPNM-positive cases was significantly poorer than that of pathological LPNM-negative cases.

Abstract
BACKGROUND/AIM The safety of neoadjuvant chemoradiotherapy (NACRT) combined with total mesorectal excision (TME) and selective lateral pelvic lymph node dissection (LLND) is unclear in elderly patients with locally advanced rectal cancer (LARC). PATIENTS AND METHODS Forty-two patients with LARC underwent TME and selective LLND following NACRT at Kobe University Hospital. The clinical outcomes were retrospectively compared between the elderly (aged ≥70 years, n=13) and non-elderly patients (aged <70, n=29). RESULTS Twelve of the thirteen elderly patients could complete NACRT. Although the overall rate of postoperative complications did not differ between the groups, abdominal wound infection and deep vein thrombosis developed more frequently in the elderly group. The length of the postoperative hospital stay was similar. Three-year overall survival and 3-year relapse-free survival rates were similar between the groups. CONCLUSION Selective LLND after NACRT is safe for elderly patients with LARC.

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.

Abstract
AIM Pelvic lymphocele is a common complication that develops after pelvic lymph node dissection. The incidence of pelvic lymphocele formation has been reported to be 10.5-51% after gynaecological or urological procedures. However, no evidence has been reported thus far with regard to the development of pelvic lymphocele following lateral pelvic lymph node dissection (LPND) for low rectal cancer. The aim of this study was to investigate the incidence of and risk factors for lymphocele formation after LPND for low rectal cancer and to examine its clinical management. METHOD We retrospectively analysed the incidence of and risk factors for pelvic lymphocele formation after LPND for rectal cancer in our hospital between January 2012 and December 2017. We also compared the size of the lymphocele between asymptomatic and symptomatic patients by using CT volumetry and examined its clinical management. RESULTS A total of 30 out of 98 patients (30.8%) developed pelvic lymphocele after rectal LPND. The number of resected nodes was significantly higher in patients with a pelvic lymphocele (P < 0.01). The median volume was significantly higher in patients with symptomatic pelvic lymphocele (P = 0.011). Among the nine symptomatic patients, two underwent CT-guided drainage, one underwent transurethral ureteral stent placement and one underwent laparoscopic marsupialization. CONCLUSION It is essential to keep in mind the possibility of pelvic lymphocele formation during follow-up of patients who undergo LPND, and to consider an appropriate treatment when these patients are symptomatic.

Abstract
The presence of lateral pelvic lymph nodes (LPLN) in advanced rectal cancer entails challenges with ongoing debate regarding the role of prophylactic dissection vs. neoadjuvant radiation treatment. This article highlights the most recent data of both approaches: bilateral LPLN dissection in every patient with low rectal cancer (Rb) as per the Japanese guidelines, vs. the developing approach of neoadjuvant radiotherapy as per Eastern countries. In addition, we also accentuate the importance of a combined approach published by Sammour et al. where a simple "one-size-fits-all" strategy should be abandoned. Rectal cancer treatment is well-established in Western countries. Patients with advanced rectal cancer will undergo radiation ± chemo neoadjuvant therapy followed by TME. In the Dutch TME trial, TME plus radiotherapy showed that the presacral area was the most frequent site of recurrence and not the lateral pelvic wall. Supporting this data, the Swedish study also concluded that LPLN metastasis is not an important cause of local recurrence in patients with low rectal cancer. Therefore, Western approach is CRM-orientated and prophylactic LPLN dissection is not performed routinely as the NCCN guideline does not recommend its surgical removal unless metastases are clinically suspicious. The paradigm in Eastern countries differs somewhat. The Korean study demonstrated that adjuvant radiotherapy without lateral lymph node dissection was not enough to control local recurrence and LPLN metastases. The Japanese Trial JCOG 0212 demonstrated the effects of LPLN dissection in reducing local recurrence in the lateral pelvic compartment. We agree with Sammour and Chang on the fact that rather than a mutual exclusivity approach, we should claim for an approach where all available modalities are considered and used to optimize treatment outcomes, classifying patients into 3 categories of LPLN: low risk cT1/T2/earlyT3 (and Ra) with clinically negative LPLN on MRI; Moderate risk (cT3+/T4 with negative LPLN on MRI) and high risk (clinically abnormal LPLN on MRI). Treatment modality should be based on detailed pretreatment workup and an individualized approach that considers all options to optimize the treatment of patients with rectal cancer in the West or the East.

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
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
Lateral pelvic lymph nodes (LPLN) in mid-/low rectal cancer pose a theoretical and practical challenge for the clinician and the patient, with geographical differences in management based on historical competing priorities. Although there has been a tendency to think of neoadjuvant radiation versus intraoperative LPLN dissection as a binary choice, they should be more constructively seen as complementary options in the personalized management of patients with rectal cancer. Herein we propose one potential algorithm for using these treatment options in this way based on local preoperative staging and the current evidence available. We also outline future research priorities in this area with the aim of answering several residual questions that remain.

Abstract
Because of recent advances in medical technology and new findings of clinical trials, treatment options for colorectal cancer are evolutionally changing, even in the last few years. Therefore, we need to update the treatment options and strategies so that patients can receive optimal and tailored treatment. The present review aimed to elucidate the recent global trends and update the surgical treatment strategies in colorectal cancer by citing the literature published in the last 2 years, namely 2016 and 2017. Although laparoscopic surgery is still considered the most common approach for the treatment of colorectal cancer, new surgical technologies such as transanal total mesorectal excision, robotic surgery, and laparoscopic lateral pelvic lymph node dissection are emerging. However, with the recent evidence, superiority of the laparoscopic approach to the open approach for rectal cancer seems to be controversial. Surgeons should notice the risk of adverse outcomes associated with unfounded and uncontrolled use of these novel techniques. Many promising results are accumulating in preoperative and postoperative treatment including chemotherapy, chemoradiotherapy, and targeted therapy. Development of new biomarkers seems to be essential for further improvement in the treatment outcomes of colorectal cancer patients.

Abstract
AIM The aim of this study was to compare the clinical outcomes of laparoscopic versus open surgery for total mesorectal excision (TME) with lateral pelvic lymph node dissection (LPLD) in advanced lower rectal cancer. PATIENTS AND METHODS Forty-four patients who underwent TME with LPLD for lower rectal cancer (pStage II/III) between January 2008 and December 2014 were divided into two groups according to the type of surgical approach as follows: open LPLD group (OLD, n=17) and laparoscopic LPLD group (LLD, n=27). RESULTS Operative time was comparable between the groups (p=0.15), whereas intraoperative blood loss and complication rates were significantly less in LLD than in OLD. Postoperative hospital stay was shorter in LLD than in OLD. Overall survival and local recurrence-free survival were similar in the two groups. Disease-free survival was better in LLD than in OLD, although the difference was not significant. CONCLUSION Laparoscopic TME with LPLD is safe and feasible.

Abstract
Background Although lateral pelvic lymph node (LPN) metastasis is a major cause of local recurrence in patients with rectal cancer, controversy still remains on the treatment of suspected LPN metastasis, “suspicious LPN”. We aimed to determine the optimal treatment strategies for suspicious LPN, in patients with locally advanced rectal cancer who underwent preoperative chemoradiotherapy (CRT). Materials and Methods Of 377 patients who received preoperative CRT for rectal cancer between 2006 and 2013, 84 (22.3%) had suspicious LPNs on pretreatment MRI. Patients’ characteristics, MRI findings, operative and pathologic findings, and oncologic outcomes were analyzed retrospectively. Results Of 84 patients with suspicious LPNs, 61 showed good response to CRT on posttreatment MRI (short-axis LPN diameter < 5 mm). Among them, 31 patients underwent TME alone (group A), and 30 underwent TME plus LPND (group B). The remaining 23 patients had persistently suspicious LPNs on post-CRT MRI and underwent TME plus LPND (group C). Pathologic LPN metastasis was confirmed in five patients (16.7%) in group B and 15 (62.5%) in group C. Local recurrence developed in 7 (22.6%), 0 (0%), and 4 (17.4%) patients in groups A, B, and C, respectively. Five patients (16.1%) in group A developed in situ LPN recurrences. The 3-year disease-free survival rates were 53.7%, 74.2%, and 46.9% in groups A, B, and C, respectively. Conclusions Study findings suggested that LPND cannot be omitted for patients with suspicious LPNs on pretreatment MRI even with good response to CRT. Findings from pretreatment MRI should be considered to determine whether LPND is indicated.

Abstract
The present study presented a 35-year-old female patient in whom fecal occult blood was detected in a medical check-up. Colonoscopy revealed a superficial elevated-type tumor with central depression in the lower rectum. The tumor was diagnosed as T1 deep invasive cancer. No swollen lymph nodes or distant metastasis were found on computed tomography or [18F]-fluorodeoxyglucose-positron emission tomography with computed tomography. However, a swollen right lateral pelvic lymph node (LPLN; short axis 4 mm) was revealed on magnetic resonance imaging (MRI). This lymph node exhibited high intensity on diffusion-weighted imaging (DWI), suggesting metastasis. Low anterior resection, regional lymph node dissection and right LPLN dissection (LPLD) were performed. Histological analysis revealed metastasis in the right LPLN, as suggested by the high DWI intensity. The indication for LPLD in the current Japanese guidelines is based on the tumor location and depth of invasion (≥T3), however, not on the status of LPLN metastasis in pre-operative evaluation. The present case was cT1, which is not included in this indication. DWI is sensitive for the diagnosis of lymph node metastasis of colorectal cancer, although inflammation-induced swelling of lymph nodes in advanced rectal cancer may cause a false-positive result, which is uncommon in T1 cases. Therefore, an LPLN with a high intensity DWI signal in T1 cases is likely to be metastasis-positive. Pre-operative DWI-MRI may be useful for identifying LPLN metastasis when planning the treatment strategy in these cases. The present study suggested reinvestigation of the indication for LPLD with inclusion of LPLN status on pre-operative imaging.

Abstract
BACKGROUND/AIM Preoperative chemoradiotherapy followed by total mesorectal excision (TME) is the standard treatment for stage III lower rectal cancer worldwide. However, in Japan, the standard treatment is TME with lateral pelvic lymph node dissection (LPLD) followed by adjuvant chemotherapy. We examined the safety and efficacy of adjuvant therapy with oxaliplatin, leucovorin, and 5-fluorouracil (modified FOLFOX6) after TME with LPLD. PATIENTS AND METHODS This retrospective study included 33 patients who received modified FOLFOX6 after TME with LPLD for stage III lower rectal cancer. RESULTS The overall completion rate of 12 cycles of adjuvant modified FOLFOX6 was 76%. Grade 3 or 4 neutropenia was observed in eight patients (24%). Sensory neuropathy was observed in 32 patients (97%) with 4 (12%) having a grade 3 event. The disease-free survival (DFS) rate was 45% at 3 years. CONCLUSION Adjuvant modified FOLFOX6 was feasible in patients with stage III lower rectal cancer after TME with LPLD.
