001 for both training and validation sets). A nomogram including the radiomics signature and tumor location as predictors was developed. The model showed both good calibration and good discrimination, in which C-index in the training set, 0.752 [95% confidence interval (95% CI) 0.701-0.803]; C-index in the validation set, 0.793 (95% CI 0.711-0.874).

This study developed a radiomics nomogram that incorporates tumor location and radiomics signatures, which can be useful in facilitating preoperative individualized prediction of histologic grade of GA.

The current standard D2 lymphadenectomy for gastric cancer (GC) includes dissection of lymph nodes (LNs) along the proper hepatic artery (No. 12a), however, the survival benefit remains controversial. The purpose of this study was to evaluate the pattern of No. 12a LN metastasis (LNM) in GC and explore the indications for No. 12a LN dissection.

Medical records of 413 consecutive GC patients who underwent curative surgery in Zhongshan Hospital, Fudan University between January 2015 and December 2018 were enrolled and reviewed retrospectively. The correlation between No. 12a LNM and clinicopathologic characteristics of patients was analyzed.

The overall incidence of No. 12a LNM was 2.67% (11/413). Tumor location (P=0.012), depth of tumor infiltration (P<0.01) and N stage (P=0.018) were significant factors associated with No. 12a LNM. All the tumors with No. 12a LNM involved the lower third of the stomach and were in T3-4 stages. Patients with No. 12a LNM had extensive LNM than those without (20.91±4.25

. 5.0±0.54, P<0.001). For advanced GC patients (stage III/IV) with tumors involving the lower third of the stomach, the incidence of No. 12a LNM increased to 10.7% (11/103). Patients with No. 12a LNM had a significantly poorer recurrence-free survival (RFS) (P=0.005) and overall survival (OS) (P=0.017). According to the result of multivariable Cox regression, No. 12a LNM was not an independent impact factor on RFS and OS.

The overall incidence of No. 12a LNM was low but it was much higher in GC patients who had very advanced tumors involving the lower third of the stomach. Honokiol clinical trial No. 12a LN dissection should be considered for these patients to improve the survival outcomes.

To investigate the safety and efficacy of nimotuzumab combined with radiotherapy for elderly patients with non-resectable esophageal carcinoma (EC).

Eligible patients were aged 70 years or older and had treatment-naïve, histologically proven inoperable locally advanced EC. Enrolled patients received radiotherapy with a total dose of 50-60 Gy in 25-30 fractions, concurrent with weekly infusion of nimotuzumab. The primary end point was the rate of more than grade 3 toxicities.

From June 2011 to July 2016, 46 patients with stage II-IV EC with a median age of 76.5 years were enrolled. There were 10, 28 and 8 patients with stage II, III and IV disease, respectively. The common acute toxicities included esophagitis (grade 1-2, 75.4%; grade 3, 8.7%), pneumonitis (grade 1, 4.3%; grade 2, 6.5%; grade 3, 2.2%), leukopenia (grade 1-2, 60.9%; grade 3-4, 4.4%), gastrointestinal reaction (grade 1-2, 17.3%; grade 3, 2.2%), thrombocytopenia (grade 1-2, 21.7%; grade 3, 2.2%), and radiothermitis (grade 1-2, 39.2%). The incidence of grade 3-4 adverse effects was 17.4%. No grade 5 toxicities were observed. Clinical complete response, partial response, stable disease, and progressive disease were observed in 1 (2.2%), 31 (67.4%), 12 (26.1%), and 2 (4.3%) patients, respectively. The median overall survival (OS) and progression-free survival (PFS) were 17 and 10 months, respectively. The 2-, 3-, and 5-year OS and PFS rates were 30.4%, 21.7%, 19.6%, and 26.1%, 19.6%, 19.6%, respectively.

Nimotuzumab combined with radiotherapy is a safe and effective therapy for elderly patients who are not surgical candidates. Further studies are warranted to confirm its therapeutic effects in elderly EC patients.

Laparoscopic resection is increasingly performed for gastrointestinal stromal tumors (GISTs). However, the laparoscopic approach for GISTs located in the esophagogastric junction (EGJ-GIST) is surgically challenging. This study compares the efficacy of laparoscopic surgery and the open procedure for EGJ-GIST through the propensity score weighting (PSW) method.

Between April 2006 and April 2018, 1,824 surgical patients were diagnosed with primary gastric GIST at four medical centers in South China. Of these patients, 228 were identified as EGJ-GISTs and retrospectively reviewed clinicopathological characteristics, operative information, and long-term outcomes. PSW was used to create the balanced cohorts.

PSW was carried out in laparoscopic and open-surgery cohorts according to year of surgery, sex, age, body mass index (BMI), tumor size, mitotic rates and recurrence risk. After PSW, 438 patients consisting of 213 laparoscopic (L group) and 225 open surgery (O group) patients were enrolled. After PSW, the survival.

Laparoscopic surgery for EGJ-GIST is associated with the advantages of shorter operative time, reduced blood loss, shorter time to liquid intake, and shorter length of stay, all without compromising postoperative outcomes and long-term survival.

Multi-center data on the current status and trends of breast reconstruction after mastectomy in China are lacking. Herein, we conducted a cross-sectional survey to investigate the current clinical practice pattern of postmastectomy breast reconstruction among Chinese female patients with breast cancer.

A standardized questionnaire used to collect information on breast reconstruction among females diagnosed with breast cancer was distributed by 31 members of the Chinese Society of Breast Surgery between January 1, 2018 and December 31, 2018. Information was collected on tumor characteristics, treatment, mesh application, nipple-areola complex (NAC) preservation, postoperative complications, bilateral reconstruction, patient satisfaction and local recurrence. The overall rate of breast reconstruction was assessed, and the characteristics were compared across patient groups with different reconstruction approaches.

A total of 1,554 patients underwent breast reconstruction after total mastectomy, with a reconstruction rate of 9.
