Background: In locally advanced, operable esophageal squamous cell carcinoma (ESCC), neoadjuvant immunochemotherapy (nICT) has shown results that are somewhat comparable to those of standard neoadjuvant chemoradiotherapy (nCRT). The impact of these neoadjuvant treatments on survival outcomes, however, has yet to be elucidated.

Methods: This study included 489 patients with locally advanced ESCC who underwent surgery at Sichuan Cancer Hospital after receiving neoadjuvant treatment between June 2017 and September 2023.

Article Synopsis
  • Oesophageal squamous cell carcinoma (OSCC) is a major health issue, especially in East Asia, and this study focuses on the long-term outcomes of patients who smoke and drink.
  • A retrospective analysis of patient data from Sichuan Cancer Hospital revealed that smokers had a median overall survival (OS) of 36.6 months, while non-smokers had 66.2 months; drinkers had 34.4 months compared to non-drinkers' 52.0 months, indicating a significant impact of these habits on survival rates.
  • Despite the overall negative effects on OS, there were no significant survival differences among patients who only smoked, only drank, or engaged in both habits.

  • - The phase 2 trial assessed the effectiveness of a treatment combining paclitaxel, carboplatin, and toripalimab in patients with advanced esophageal squamous cell carcinoma (ESCC), with a median progression-free survival time of 9.8 months.
  • - Secondary results showed a 45.5% objective response rate and a 57.6% disease control rate, while the 1-year progression-free survival and overall survival rates were 41.9% and 69.7%, respectively.
  • - The most common serious side effect was lymphopenia (82%), and no treatment-related deaths were reported, suggesting that this approach may be safe and effective enough for further investigation in larger trials.

Background: Programmed death ligand 1 (PD-L1) score is an important companion diagnosis to predict the response to immunotherapy. Immunohistochemistry can accurately assess the expression of PD-L1 in routine paraffin-embedded tissue. However, whether decalcified or depigmented tissue is still accurate and can be used as a companion diagnosis is controversial.

T-cell lymphoma is a highly invasive tumor with significant heterogeneity. Invasive tissue biopsy is the gold standard for acquiring molecular data and categorizing lymphoma patients into genetic subtypes. However, surgical intervention is unfeasible for patients who are critically ill, have unresectable tumors, or demonstrate low compliance, making tissue biopsies inaccessible to these patients.

Background And Purpose: To assess the relationship between metastatic lymph node (LN) responder status and recurrence-free survival (RFS) in patients undergoing neoadjuvant chemoradiotherapy (NCRT).

Materials And Methods: We retrospectively reviewed 304 patients with local advanced esophageal squamous cell carcinoma received NCRT followed by esophagectomy. For 112 patients with positive node, according to the proportion of residual viable tumor cells area within the whole tumor beds of all metastatic LNs, we classified LN-tumor regression grade (LN-TRG) into four categories: grade 1, 0%; 2, <10%; 3, 10%-50%; 4, >50%.

Background: A recurrence-free survival (RFS) prediction model was developed and validated for patients with locally advanced esophageal squamous cell carcinoma treated with neoadjuvant chemoradiotherapy (NCRT) in combination with surgery.

Patients And Methods: We included 282 patients with esophageal squamous cell carcinoma who received neoadjuvant chemoradiotherapy (NCRT) combined with surgery, constructed three models incorporating pathological factors, investigated the discrimination and calibration of each model, and compared the clinical utility of each model using the net reclassification index (NRI) and the integrated discrimination index (IDI).

Results: Multivariable analysis showed that pathologic complete response (pCR) and lymph node tumor regression grading (LN-TRG) (p < 0.

Ovarian cancers are the major cause of mortality for women worldwide. This study was aimed to elucidate the biological activities of CCDC106 in the proliferation and invasion of mutant p53 and of wild-type p53 ovarian cancer cells. CAOV3 (mutant p53) cells showed high expression levels of CCDC106, but it was expressed at low levels in SKOV3 (mutant p53) and in A2780 (wild-type p53) cells.

Article Synopsis
  • The study compared the effects of neoadjuvant immunochemotherapy (NICT) and neoadjuvant chemoradiotherapy (NCRT) on esophageal squamous cell carcinoma (ESCC) in 28 patients divided into two groups for treatment.
  • It evaluated the expression and changes of PD-L1, a protein linked to immune response, finding that both treatments increased PD-L1 levels, with NCRT causing a more significant rise compared to NICT.
  • Although NICT was not less effective than NCRT in terms of tumor response, the study concluded that preoperative PD-L1 scores were not good predictors of treatment effectiveness, while changes in PD-L1 expression (specifically IPS) could be linked to the

It is well established that estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor (HER2) could be regarded as prognostic factors in breast cancer. Ultrasound-guided fine needle aspiration cytology (FNAC) has revolutionized the management of cancers, providing less invasive and quick diagnostic method. There are hardly any studies on the correlation between cytomorphology and prognostic biomarkers.

Dysfunction of energy metabolism can be a significant and fundamental pathophysiological basis for strokes. In studies of both humans and rodents, resveratrol, a natural polyphenol, has been reported to provide protection from cerebral ischemic injury by regulating expression of silent mating type information regulation 2 homolog 1 (SIRT1). However, direct evidence demonstrating that resveratrol exerts neuroprotection from cerebral ischemia injury by decreasing energy consumption is still lacking.
