The analysis aimed to assess whether the reduction in radiation therapy dosage affected patients' local control and survival.

Real-world data of immunotherapy from China in recurrent or metastatic head and neck squamous cell carcinoma.

Purpose: Immune checkpoint inhibitors (ICIs) have become a standard therapy for recurrent or metastatic head and neck squamous cell carcinoma (R/MHNSCC), however, there are still unanswered questions about immunotherapy. Furthermore, immunotherapy for R/MHNSCC of the mainland Chinese population are lacking. The aim of this study is to evaluate the efficacy and safety of ICIs in real-world settings in China.

The relationship between the radiation dose of pelvic-bone marrow and lymphocytic toxicity in concurrent chemoradiotherapy for cervical cancer.

Objective: The purpose of this study is to verify the correlation between medium and low radiation doses of the pelvic-bone marrow and the incidence of lymphocytic toxicity during concurrent chemoradiotherapy for cervical cancer.

Materials And Methods: This research included 117 cervical cancer patients, who received concurrent chemoradiotherapy. Radiotherapy included external-beam radiation therapy and brachytherapy.

A multi-omics approach based on H-NMR metabonomics combined with target protein analysis to reveal the mechanism of RIAISs on cervical carcinoma patients.

Cervical carcinoma (CC) is the fourth most common cancer in females and radiotherapy is always as the definitive therapy for cervical cancer patients who are not suitable for surgery. Radiation-induced acute intestinal symptoms (RIAISs) occur in 50-80% of cervical cancer patients. Some research shows that RIAISs may relate to inflammatory reaction by radiotherapy but the action mechanism is also not clearly and the details of the molecular mechanism are still urgently needed.

miR-30a radiosensitizes non-small cell lung cancer by targeting ATF1 that is involved in the phosphorylation of ATM.

Increasing number of studies report that microRNAs play important roles in radiosensitization. miR-30a has been proved to perform many functions in the development and treatment of cancer, and it is downregulated in non-small cell lung cancer (NSCLC) tissues and cells. This study was conducted to understand if miR-30a plays a role in the radiosensitivity of NSCLC cells.

[Progress on clinical application of bevacizumab for the treatment of refractory cervical cancer].

Bevacizumab is increasingly used in recurrent, persistent or metastatic cervical cancer. The early retrospective case reports found that bevacizumab combined with 5-FU (including capecitabine) or paclitaxel was well tolerated and displayed encouraging anti-tumor activity in recurrent or persistent cervical cancer. Phase Ⅱ clinical trials showed that bevacizumab was well tolerated and active in the second- and third-line treatment of patients with recurrent cervical cancer.

Peritoneal bladder fistula following radiotherapy for cervical cancer: A case report.

The occurrence of a peritoneal bladder fistula as a result of radiation cystitis following radiotherapy for cervical cancer is extremely rare and, to the best of our knowledge, has not been reported previously. The present study reports the case of a 50-year-old woman who was diagnosed with cervical cancer 20 years previously and was treated with radiotherapy. The patient was diagnosed with radiation cystitis 10 years ago, which was treated with Chinese medicine, and began experiencing sudden abdominal pain and bowel difficulties following urination 3 years ago.

The effect of interferon gamma on conventional fractionated radiation-induced damage and fibrosis in the pelvic tissue of rabbits.

We aim to investigate the effect of interferon gamma (IFN-γ) on conventional fractionated radiation-induced damage and fibrosis in ureter and colorectal mucosa. Fifty-two rabbits were randomly divided into three groups comprising a conventional radiation group, an IFN-γ group, and a control group. X-rays were used to irradiate the pelvic tissues of the rabbits in the IFN-γ and conventional radiation groups.

Association of DNA repair gene polymorphisms with response to cisplatin-based concurrent chemoradiotherapy in patients with cervical carcinoma.

Purpose: The aim of this study was to investigate polymorphisms in DNA repair genes as potential predictive factors among Chinese cervical cancer patients.

Methods: A total of 72 patients with cervical carcinoma, who received cisplatin-based chemoradiotherapy and whose responses were evaluated by Response Evaluation Criteria in Solid Tumors, were included. The association between response to chemoradiotherapy and the genotypes for 29 single-nucleotide polymorphisms (SNPs) in 25 DNA repair genes were analyzed.

Cost-effectiveness of radical hysterectomy with adjuvant radiotherapy versus radical radiotherapy for FIGO stage IIB cervical cancer.

Objective: Recent literature reports that radical hysterectomy followed by adjuvant radiotherapy has comparable progression-free survival and overall survival compared to radical radiotherapy for International Federation of Gynecology and Obstetrics stage IIB cervical cancer. Now, we evaluate the cost-effectiveness (CE) of these two treatment regimens.

Primary And Secondary Outcome Measures: A decision-tree model was constructed comparing CE between treatment arms using the published studies for overall survival rates and treatment-related toxicity rates for 5 years.

A Randomized Controlled Trial Comparing Clinical Outcomes and Toxicity of Lobaplatin- Versus Cisplatin-Based Concurrent Chemotherapy Plus Radiotherapy and High-Dose-Rate Brachytherapy for FIGO Stage II and III Cervical Cancer.

Background: We designed this randomized controlled trial (RCT) to assess whether lobaplatin-based concurrent chemotherapy might be superior to cisplatin-based concurrent chemotherapy for FIGO stage II and III cervical cancer in terms of efficacy and safety.

Materials And Methods: This prospective, open-label RCT aims to enroll 180 patients with FIGO stage II and III cervical cancer, randomly allocated to one of the three treatment groups (cisplatin 15mg/m2, cisplatin 20mg/m2 and lobaplatin 35mg/m2), with 60 patients in each group. All patients will receive external beam irradiation (EBRT) and high-dose-rate intracavitary brachytherapy (HDR-ICBT).

Application of 1H NMR spectroscopy-based metabonomics to feces of cervical cancer patients with radiation-induced acute intestinal symptoms.

Objective: Radiation-induced acute intestinal symptoms (RIAISs) are a common complication of radiotherapy for cervical cancer. The aim of this study was to use (1)H nuclear magnetic resonance ((1)H NMR) combined with chemometric analysis to develop a metabolic profile of patients with RIAISs.

[Metabonomics-a useful tool for individualized cancer therapy].

Metabonomics has developed rapidly in post-genome era, and becomes a hot topic of omics. The core idea of metabonomics is to determine the metabolites of relatively low-weight molecular in organisms or cells, by a series of analytical methods such as nuclear magnetic resonance, color spectrum and mass spectrogram, then to transform the data of metabolic pattern into useful information, by chemometric tools and pattern recognition software, and to reveal the essence of life activities of the body. With advantages of high-throughput, high-sensitivity and high-accuracy, metabolomics shows great potential and value in cancer individualized treatment.

A meta-analysis of reference values of leptin concentration in healthy postmenopausal women.

Metastasis to the parotid region as an initial presentation of renal cell carcinoma: A case report.

Distant metastasis of renal cell carcinoma (RCC) to the parotid region is extremely rare, particularly as an initial presentation. In the present study, we report a rare case of parotid region metastasis from RCC as an initial presentation in a 44-year-old female who presented with a painless lump in the right parotid region. Investigation revealed RCC in the left renal region and metastasis to the right iliac area.
