Article Synopsis
  • Undifferentiated tonsillar carcinoma is a rare and difficult-to-treat head and neck cancer that often resists chemotherapy.
  • In a reported case, a patient with advanced cancer showed a BRCA1 mutation and high tumor mutational burden from next-generation sequencing, leading to treatment with PARP inhibitors and immune checkpoint inhibitors.
  • The patient achieved a partial response with significant progression-free and overall survival, highlighting the potential of molecular profiling in shaping treatment strategies for rare cancers.

Background: The high heterogeneity of ovarian cancer (OC) brings great difficulties to its early diagnosis and prognostic forecast. There is an urgent need to establish a prognostic model of OC based on clinicopathological features and genomics.

Methods: We identified hypoxia-related differentially expressed genes (DEGs) between OC tissues from The Cancer Genome Atlas (TCGA) and normal tissues from the Genotype-Tissue Expression (GTEx).

Background: An extremely rare condition, radiation-induced angiosarcoma is characterized by a poor prognosis, high recurrence rate and lack of effective treatment. Herein, we present a case report of a 48-year-old female patient with radiation-induced abdominal wall angiosarcoma who showed a dramatic response to low-dose apatinib.

Case Presentation: The patient, who was diagnosed with cervical squamous cell carcinoma 20 years ago, had received radiotherapy and chemotherapy after operation.

Rationale: Syncope caused by head and neck cancer (HNC) is rare. However, syncope caused by tongue cancer (TC) is even rarer. In TC, syncope is caused by tumor-mediated compression of the carotid sinus and stimulation of the glossopharyngeal nerve.

Objective To preliminarily observe miRNA gene profiles in benefit serum of advanced non-small cell lung cancer (NSCLC) treated by TCM combined Western medicine (WM) , and to seek for molecular markers for its efficacy monitoring and prediction. Methods Recruited were 5 advanced NSCLC patients who received TCM combined WM treatment and obtained efficacy benefit ( as the treatment group) , 3 advanced NSCLC patients who received early treatment ( as the lung cancer group) , and 3 healthy subjects (as the control group). Serum samples were collected and total RNA was extracted using Trizol method.

The weight-loaded swimming capability, tumor growth, survival time and biochemical markers of Ganoderma lucidum polysaccharides (GLPs) in a chemotherapy-related fatigue mouse model were tested in the present study. The results showed that the middle-dose GLPs (GLP-M) and the high-dose GLPs (GLP-H) could increase the exhausting swimming time, which was observed to decrease in the cisplatin control group(PCG) and the tumor control group (TCG).The GLP-M and the GLP-H had reduced serum levels of tumor necrosis factor-αand interleukin-6, which were up-regulated by cisplatin.
