Conformal sphincteric resection for ultra-low rectal cancer located below the dentate line: A pilot report.

Aim: Sphincter-sparing surgery can be achieved in most cases of low rectal cancer with the development of intersphincteric resection. However, abdominoperineal resection is still inevitable for patients with tumours located below the dentate line. To address this, we have developed a procedure called conformal sphincteric resection (CSR) in which the corresponding part of the subcutaneous portion of the external anal sphincter and the perianal skin on the tumour side is removed to achieve a safe distal resection margin and lateral resection margin while the dentate line and the internal anal sphincter on the tumour-free side are preserved as much as possible, to achieve sphincter preservation without compromising oncological safety and functional acceptability, and to render tumour location no longer a contraindication for sphincter-sparing surgery.

Construction and validation of a prognostic nomogram for locally recurrent rectal cancer: a population-based study.

Background: Postoperative recurrence was a life-threatening condition for patients with rectal cancer. Due to the heterogeneity of locally recurrent rectal cancer (LRRC) and controversy of the optimal treatment for patients, it was difficult to predict the prognosis of LRRC. This study aimed to develop and validate a nomogram that could accurately predict the survival probability of LRRC.

An anatomical study on intersphincteric space related to intersphincteric resection for ultra-low rectal cancer.

Background: Intersphincteric resection (ISR) has been proposed to offer sphincter-sparing solution for patients with ultra-low rectal cancer. However, complete and accurate concepts about the intersphincteric space (ISS) related anatomy are not demonstrated clearly. This study aimed to provide a comprehensive description about the anatomic structure of ISS related to ISR.

Whole-exome sequencing of rectal cancer identifies locally recurrent mutations in the Wnt pathway.

Locally recurrent rectal cancer (LRRC) leads to a poor prognosis and appears as a clinically predominant pattern of failure. In this research, whole-exome sequencing (WES) was performed on 21 samples from 8 patients to search for the molecular mechanisms of LRRC. The data was analyzed by bioinformatics.

CD3D is associated with immune checkpoints and predicts favorable clinical outcome in colon cancer.

The T cell receptor-CD3 complex has shown great potential in tumor therapy. However, there is currently no research on CD3D in tumors. Correlation between CD3D expression and clinical parameters and immune checkpoints of of colon adenocarcinoma (COAD) were analyzed.

The Role Of Hepatic Stellate Cells In Promoting Liver Metastasis Of Colorectal Carcinoma.

Purpose: Colorectal cancer (CRC) is the most common malignancy in the gastrointestinal tract. The liver is the most common location of CRC metastases, which are the main causes of CRC-related death. However, the mechanisms underlying metastasis of CRC to the liver have not been characterized, resulting in therapeutic challenges.

Intraoperative monitoring of pelvic autonomic nerves during laparoscopic low anterior resection of rectal cancer.

Background: Some patients with low rectal cancer experience anorectal and urogenital dysfunctions after surgery, which can influence the long-term quality of life. In this study, we aimed to protect nerve function in such scenarios by performing intraoperative monitoring of pelvic autonomic nerves (IMPAN).

Patients And Methods: We retrospectively investigated a series of 87 patients undergoing laparoscopic low anterior resection of rectal cancer.

A long noncoding RNA MAP3K1-2 promotes proliferation and invasion in gastric cancer.

Background: Long noncoding RNAs (lncRNAs) have been implicated in several human cancers. The expression profile and underlying mechanism of the lncRNA MAP3K1-2 in gastric cancer (GC) are poorly understood.

Methods: Sixty-one patients with GC were recruited from Shanghai Baoshan Luo Dian Hospital (Shanghai, China).

The analysis of clinicopathologic predictors of lymph node metastasis and postoperative recurrence in patients with papillary thyroid microcarcinoma from Guangdong Province, China-a multicenter retrospective study.

Purpose: Currently the extent of lymph node dissection (LND) for papillary thyroid microcarcinoma (PTMC) remains controversial. The present study aims to investigate the clinicopathologic predictors of lymph node metastasis (LNM) and prognosis in PTMC patients from Guangdong to enable appropriate treatment and follow-up.

Methods: Data including demographics, tumor size, multifocality, extrathyroidal extension (ETE) and concomitant thyroiditis were collected from 374 untreated PTMC patients from Guangdong, China.

Tumor Wide Horizontal Invasion Predicts Local Recurrence for Scrotal Extramammary Paget's Disease.

Extramammary Paget's disease (EMPD) is a rare malignancy, and little was known about its prognostic factors and optimal treatment. In the current study, we aimed to discuss clinical and pathological features of scrotal EMPD and determine the prognostic factors for cancer-specific survival and local recurrence. A total of 206 patients with scrotal EMPD lesions surgically treated at our institute were studied.

Advantages of Early Preventive Ileostomy Closure after Total Mesorectal Excision Surgery for Rectal Cancer: An Institutional Retrospective Study of 123 Consecutive Patients.

Background/aim: Preventive ileostomy is frequently constructed to minimizethe consequences of anastomotic leakage after resection of rectal cancer. There is no consensus regarding the best timing for temporary stoma closure after proctectomy for rectal cancer. This retrospective study sought to determine whether the timing of stoma closure influenced postoperative outcomes.

The prognostic value of regional lymph node metastases in patients of Guangdong Province, China with differentiated thyroid cancer: A multicenter retrospective clinical study.

Although the prognostic value of nodal metastases in differentiated thyroid cancer remains controversial, it is of interest to evaluate and understand the different characteristics of predictive outcomes.A multicenter retrospective study was conducted in 215 untreated patients with differentiated thyroid cancer from July 1997 to July 2015 in 4 medical centers of Guangdong Province. A total of 107 patients with nodal metastases (group A) were compared to 108 patients without metastases (group B).

Coordinated Digital-Assisted Program Improved Door-to-Balloon Time for Acute Chest Pain Patients.

Emergency care for patients with chest pain can be a challenge in remote areas. Digital communication technology has the potential to improve outcomes by allowing early diagnosis and faster treatment. The aim of the present study was to investigate whether implementation of a coordinated digital-assisted program (CDAP) for Chinese hospitals can reduce the door-to-balloon (D2B) time for percutaneous coronary intervention (PCI) in acute chest pain patients in China.

Prognostic value of Ki67 and p63 expressions in bladder cancer patients who underwent radical cystectomy.

Introduction: Radical cystectomy (RC) is the gold standard treatment for patients with high-risk non-muscle-invasive bladder cancer and muscle-invasive bladder cancer (MIBC) . However, despite aggressive treatment, mortality rates of patients are still high. Therefore, it is crucial to indentify some practical prognostic factors for cancer-specific survival in those patients to guide our therapeutic strategies.

Clinical safety and outcomes of laparoscopic surgery versus open surgery for palliative resection of primary tumors in patients with stage IV colorectal cancer: a meta-analysis.

Background: This study was performed to compare the clinical safety and outcomes of laparoscopic versus open surgery for primary tumors in patients with stage IV colorectal cancer.

Methods: Pertinent studies were selected from the MEDLINE, EMBASE, and Cochrane Library databases; references from published articles; and reviews. Both prospective and retrospective studies were included for the meta-analysis.
