Thirty-nine cases of hypopharyngeal and 21 cases of cervical esophageal carcinomas were resected and different organs and tissues were used for reconstruction. Among them, the stomach was used as substitute for the esophagus in 33 cases the colon in 20, the myocutaneous flap in 4 and the gastric tube in 3. Three-year and 5-year survival rates were 61.2% and 37.9% respectively. Of the post-operative deaths within 5 years, 40.5% was due to local recurrence and 35.1% due to metastasis to cervical lymphnode. In patients who had negative lymphnode findings before operation, positive results were obtained in 42.1% of the cervical lymphnodes and in 27.2% of the tracheoesophageal groove and superior mediastinal lymphnodes resected. Reoperation was performed in 5 cases with local recurrence and 8 cases with cervical lymphnode metastasis and the resectabilities were 40.1% and 37.9% respectively. The authors consider that among these operative procedures, the colonic interposition with pharyngocolonic anastomosis had the following advantages: (1) excellent physiological function; (2) higher successful rate; (3) lower local recurrence incidence; and (4) good living quality.

Motivation: The accurate prediction of O-GlcNAcylation sites is crucial for understanding disease mechanisms and developing effective treatments. Previous machine learning models primarily relied on primary or secondary protein structural and related properties, which have limitations in capturing the spatial interactions of neighboring amino acids. This study introduces local environmental features as a novel approach that incorporates three-dimensional spatial information, significantly improving model performance by considering the spatial context around the target site.

Objective: We evaluated the accuracy of oncologists' estimates of expected survival time in recurrent ovarian cancer.
Methods: Oncologists estimated expected survival time at baseline for each patient, who were then followed up for survival time. We hypothesized that oncologists' estimates of expected survival time would be independently significant predictors of survival, unbiased (approximately equal proportions [50%] living longer versus shorter than their expected survival time), or imprecise (<30% within 0.

Objective: We sought to determine the safety and efficacy of the oral progesterone antagonist onapristone in combination with anastrozole in patients with recurrent progesterone receptor-positive adult-type granulosa cell tumor of the ovary.
Methods: This was a single-institution phase II study of patients with progesterone receptor-positive adult-type granulosa cell tumor who received at least 1 prior line of chemotherapy. Patients were enrolled from November 2021 to August 2022 and tissue was evaluated for progesterone receptor status via immunohistochemistry.

Background: Preoperative neoadjuvant chemoradiotherapy (nCRT) is considered to be the standard treatment strategy for locally advanced rectal cancer (LARC); however, the risk of adverse events and postoperative recurrence remains significant. This study aimed to evaluate the non-inferiority of neoadjuvant chemotherapy (nCT) compared with nCRT in patients with LARC and to assess the possibility of eliminating radiotherapy on the basis of guaranteed efficacy.
Materials And Methods: We searched the PubMed, Embase, and Cochrane Library databases to identify randomized controlled trials (RCTs) comparing the efficacy of nCRT and nCT for LARC.

Objectives: Cutaneous adnexal carcinomas (CACs) are rare skin cancers with no established treatment guidelines. Given the limited data, this study aims to explore the characteristics and outcomes of patients with CAC treated with radiation therapy (RT).
Methods: Patients diagnosed with CAC between 2000 and 2020 who received RT were included.
