Because of their rarity, there are no clear guidelines for the treatment of anal carcinomas; such tumors are normally subjected to the same modalities as recommended for rectal cancer. We report a patient with anal canal mucinous adenocarcinoma, with metastases in the pararectal and right inguinal lymph nodes, who was treated with abdominoperineal resection followed by mFOLFOX6 chemotherapy for 6 months (12 cycles). The patient has remained recurrence-free thus far, approximately 2 years since the surgery. As the optimal treatments for anal carcinomas have not been fully elucidated, we present this case to highlight a possible course of action for such patients that appears to be effective and promising.

Abstract Objective This study aimed to explore the pathological characteristics of lymph nodes around inferior mesenteric artery in rectal cancer and its risk factors and its impact on tumor staging. Methods 485 rectal cancer patients underwent proctectomy surgery were collected in this study. Clinical features of patients, including gender, age, BMI, tumor size, pathological type, differentiation, nerve invasion, lymph nodes, tumor marker, and pathological examinations, were analyzed. Results A total of 485 cases were included in this study. There were 29 cases with IMA-LN metastasis; the metastasis rate was 5.98% (29/485). Positive IMA-LNs were associated with distance from anal verge, CEA, pathological type, differentiation, nerve invasion, T stage, and N stage. Multivariate analysis showed that distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. Conclusion Distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. No skip metastasis occurred in IMA-LNs. We should choose the appropriate surgical methods to achieve better oncological results and reduce the incidence of postoperative complications.

Abstract Background: In contrast to open-surgery abdominoperineal excision (APE) for rectal cancer, postoperative perineal hernia (PPH) is reported to increase after extralevator APE and endoscopic surgery. In this study, therefore, we aimed to determine the risk factors for PPH after endoscopic APE.Methods: A total 73 patients who underwent endoscopic APE for lower rectal cancer were collected from January 2009 to March 2020, and the risk factors for PPH were analyzed retrospectively.Results: Nineteen patients (26%) developed PPH after endoscopic APE, and the diagnosis of PPH was made at 9–393 days (median: 183 days) after initial surgery. Logistic regression analysis showed that absence of pelvic peritoneal closure alone increased the incidence of PPH significantly (odds ratio; 13.76, 95% confidence interval; 1.48–1884.84, p = 0.004).Conclusions: Pelvic peritoneal closure should be performed when possible after endoscopic APE to prevent PPH.

Lymphatic metastasis in papillary thyroid cancer (PTC) is eminent; however, the extent of central compartment lymph nodes dissection (CCD) is controversial and requires the knowledge of pattern and risk factors for central compartment lymph nodes metastasis (CCM). We did a prospective study of 47 cases with PTC who underwent total thyroidectomy (TT) with CCD with/without lateral lymph nodes dissection (LND). Clinicopathological profile including CCM as ipsilateral and contralateral was documented. On histopathology, the mean tumour size was3.57±2.42 cm 59.6% had CCM, which was bilateral in the majority (60.72%). The tumour-size was the most important predictor for lymph nodes metastasis-(P=0.018) whereas multicentricity-(P=0.002) and ipsilateral CCM-(P=0.001) were the predictors for contralateral CCM. The long-term morbidity of CCD done in primary setting is comparable with TT-alone. Bilateral CCD should be done with thyroidectomy in PTC, otherwise the risk of residual diseases and subsequent recurrence is high. The long-term morbidity is comparable in experienced hands.

120 Background: Which patients with lower rectal cancer are at risk of inguinal lymph node metastasis (ILNM) and how to treat ILNM remain unclear. This study aimed to clarify the predictors of ILNM and clinical significance of treatment for ILNM. Methods: Consecutive patients with rectal adenocarcinoma invading the anal canal who underwent curative surgery between 2003 and 2019 at a single institution were retrospectively reviewed. The pathological nodal involvement in mesorectal, lateral pelvic or inguinal lymph nodes (ILN) at the time of rectal surgery and of later onset were collectively defined as final nodal metastasis (f-LNM) in this study. Factors associated with f-LNM were analyzed. Moreover, the ‘modified therapeutic value index’ defined by the 5-year overall survival rate of patients treated against f-LNM multiplied by their frequency was calculated for each lymph node area. Results: A total of 145 patients were enrolled, among whom16 patients developed ILNM. For predicting f-ILNM, the cutoff 8.5 mm of ILN diameter gave area under the curve of 0.889. Dentate line involvement and ILN larger than a simplified cutoff of 8 mm were independently associated with the development of ILNM (odds ratio: 33.4 and 11.9, respectively). The modified therapeutic value indice of inguinal, lateral pelvic and mesorectal LNs in the entire population were 6.1, 8.2 and 20.3 points, respectively. In patients with dentate line invaded by cancer, they were 11.7, 5.8 and 16.2 points, respectively. Moreover, the index of ILN was 21.1 points when confined to patients with ILN larger than 8 mm. Conclusions: Dentate line involvement and ILN larger than 8 mm were predictive of developing ILNM in patients with rectal cancer invading the anal canal. Treatment of ILNM may be recommended for patients manifesting the above predictors, given the significant therapeutic outcomes.
