ABSTRACT

Background: The association between sex and the survival of patients with esophageal cancer (EC) remains controversial. We sought to systematically investigate sex-based disparities in EC survival using the Surveillance, Epidemiology, and End Results (SEER) registry data from the United States. Methods: Patients with EC diagnosed from 2004 to 2015 registered in the SEER database were selected. The association between sex and cancer-specific survival (CSS) was evaluated using survival analysis. The Inverse Probability Weighting (IPW) approach was applied to reduce the observed bias between males and females. Subgroup analyses were used to investigate the robustness of the sex-based disparity and to explore potential interaction effects with other variables. Results: Overall, 29,312 eligible EC patients were analyzed, of whom 5,781 were females, and 23,531 were males. Females had higher crude CSS compared to males (10-year CSS: 24.5 vs. 21.3%; P < 0.001). Similar results were obtained after adjusting for selection bias using the IPW approach and multivariate regression. Subgroup analyses confirmed the relative robustness of sex as a prognostic factor. However, significant interactions were observed between sex and other variables, such as age, race, tumor grade, histology, and treatment modality. In particular, there was no survival advantage for premenopausal females compared to their male counterparts, but the association between sex and EC survival was prominent in 46-55-year-old patients. Conclusions: Female EC patients had better long-term survival than males. The association between sex and EC survival vary according to age, race, tumor grade, histology, and treatment modality. Sex-based disparity in EC-specific survival was age-related in the United States population.

ABSTRACT

OBJECTIVE: To explore the predictive value of diffusion-weighted imaging (DWI) in evaluating the short-term efficacy of concurrent chemoradiotherapy (CCRT) in the treatment of patients with non-small cell lung cancer (NSCLC). METHODS: A total of 192 patients with NSCLC were selected and treated with CCRT. Dynamic contrast-enhanced magnetic resonance imaging combined with DWI was performed on all patients before and after CCRT treatment. Correspondingly, apparent diffusion coefficient (ADC) values were recorded before treatment (ADCpre), during treatment (ADCmid), and after treatment (ADCpost). Tumor response was evaluated as complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD). Receiver operating characteristic (ROC) curves were used to evaluate the diagnostic power of quantitative DWI parameters in predicting the short-term efficacy of CCRT for patients with NSCLC. RESULTS: There were 21 patients with CR, 82 with PR, 77 with SD, and 12 with PD. The ADCpre was negatively correlated with tumor regression rate, whereas ADCmid, ADCpost, and their respective change rates ∆ADCmid and ∆ADCpost were positively related to tumor regression rate. The ROC curve analysis suggested ADCpre = 1.38 × 10-3 mm2/s, ∆ADCmid = 14.14%, and ∆ADCpost = 20.39% as thresholds to predict the short-term efficacy of CCRT, with corresponding areas under the curve of 0.637, 0.743, and 0.752, respectively. CONCLUSIONS: These findings indicate that DWI provides promising predictive value in evaluating the short-term efficacy of CCRT in the treatment of patients with NSCLC.

ABSTRACT

OBJECTIVE: The objective of this study is to assess the use of a novel, double-lumen electrocautery tube (DLET) device for ablating the sympathetic nerve chain in patients with primary palmar hyperhidrosis (PPH). METHODS: Forty-six patients with severe PPH were recruited into the study between November 2010 and February 2012. All patients underwent single port, bilateral video-assisted thoracoscopic sympathicotomy. Twenty-four patients were randomized to receive sympathicotomy using a conventional 5-mm electrocautery hook (hook group) and 22 patients were randomized to the DLET group. RESULTS: The mean postoperative follow-up period was 8.1 months (range: 1 to 15 months). After surgery the hands of all patients became dry and warm. Mean incision size was 10.6 ± 1.0 in the hook group and 6.5 ± 0.5 mm in the DLET group (p = 0.001). The mean pain score was 1.4 ± 0.6 with hook surgery and 0.9 ± 0.6 with the DLET device (p = 0.016). The mean operative time was longer in the hook group (36.8 ± 3.4 min) than in the DLET group (30.5 ± 3.9 min; p = 0.001). There were no significant differences between the two procedures in terms of hospital stay and compensatory sweating, or patient satisfaction. Pneumothorax occurred in two (8.3%) patients in the hook group and in one (4.5%) patient in the DLET group. None of the patients required chest drainage and none developed Horner syndrome. CONCLUSIONS: Single-port video-assisted thoracoscopic sympathicotomy using hook or DLET procedures is effective, safe, and minimally invasive method for palmar hyperhidrosis. The DLET device allows a shorter operation time, smaller incision, better cosmetic results, less pain, and better clarity of video, making it suitable for single-port thoracoscopic sympathicotomy.
