The relationship of nutritional status with anticancer immunity and its prognostic value for head and neck cancer.

Malnutrition has been reported to be associated with reduced survival and deficient anticancer immunity, and undernourishment is a frequent comorbidity in head and neck cancer (HNC) patients. In this study, we evaluated the relationship between nutritional status and immunologic factors, and its prognostic value for HNC. We retrospectively reviewed 212 HNC patients who had undergone a nutrition evaluation based on the Patient-Generated Subjective Global Assessment (PG-SGA) and curative radiotherapy (RT).

Risk of critical limb ischemia in long-term uterine cancer survivors: A population-based study.

Background: The risk of critical limb ischemia (CLI) which causes ischemic pain or ischemic loss in the arteries of the lower extremities in long-term uterine cancer (UC) survivors remains unclear, especially in Asian patients, who are younger at the diagnosis of UC than their Western counterparts.

Aim: To conduct a nationwide population-based study to assess the risk of CLI in UC long-term survivors.

Methods: UC survivors, defined as those who survived for longer than 5 years after the diagnosis, were identified and matched at a 1:4 ratio with normal controls.

Effect of Proton Therapy on Tumor Cell Killing and Immune Microenvironment for Hepatocellular Carcinoma.

Radiotherapy with proton therapy (PT) has dosimetric advantages over photon therapy, which helps to enlarge the therapeutic window of radiotherapy for hepatocellular carcinoma (HCC). We evaluated the response of HCC to PT and examined the underlying mechanisms. The human liver cancer cell lines HepG2 and HuH7 and the murine liver cancer cell line Hepa1-6 were selected for cell and animal experiments to examine the response induced by PT irradiation.

Adjuvant Chemoradiotherapy Associated with Improved Overall Survival in Resected Esophageal Squamous Cell Carcinoma after Neoadjuvant Chemoradiotherapy in Intensity-Modulated Radiotherapy Era.

Background: The prognosis of patients with resected esophageal squamous cell carcinoma after neoadjuvant chemoradiotherapy is particularly poor in those who were staged as ypT3/T4 and/or ypN+. This study investigated whether adjuvant chemoradiotherapy was associated with improved clinical outcomes in these patients.

Methods: we identified patients with esophageal squamous cell carcinoma who were staged as ypT3/T4 and/or ypN+ after being treated with neoadjuvant chemoradiotherapy followed by esophagectomy between the years 2013 and 2019.

promotes tumor progression in oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) is an aggressive head and neck cancer. Evidence showed that some pathogenic bacteria are associated with periodontitis and oral cancer. The change in oral microbiome composition and the role of the specific periodontal pathogen in OSCC were investigated.

Perioperative Complications and Oncologic Outcomes after Radical Cystectomy in End-Stage Renal Disease Patients with Bladder Cancer Obtained Using a Standardized Reporting System.

Background: We investigated the use of a standardized reporting system to study perioperative complications and oncologic outcomes after radical cystectomy in end-stage renal disease (ESRD) patients with bladder cancer. Methods: We reviewed retrospective outcomes in 141 ESRD patients with bladder cancer who underwent radical cystectomy between 2004 and 2015. Complications were graded using the Clavien−Dindo classification system with 0−2 classified as “No Major Complications” and Clavien 3−5 as “Major Complications”.

Survival Impact of Nephroureterectomy for De Novo Stage IV Nonmetastatic and Metastatic Upper Tract Urothelial Carcinoma.

Background: Whether nephroureterectomy (NU) provides survival benefits in patients with stage IV upper tract urothelial carcinoma (UTUC) remains unclear. We compared the effect of chemotherapy (CT) alone with that of CT combined with NU (CT + NU) on the overall survival (OS) of patients with stage IV nonmetastatic UTUC (nmUTUC) and metastatic UTUC (mUTUC).

Patients And Methods: This multicenter retrospective cohort study included the data of patients with UTUC undergoing CT alone or CT + NU from the Chang Gung Cancer Database (2002-2015) and followed them until August 2017.

Prospective Evaluation of Taste Function in Patients With Head and Neck Cancer Receiving Intensity-Modulated Radiotherapy.

Importance: The majority of the patients with head and neck cancer (HNC) experience taste dysfunction (TD) during or after radiotherapy (RT). However, prospectively collected data for taste dysfunction have been limited, especially in the era of intensity-modulated RT (IMRT).

Objective: To evaluate the taste function in patients with HNC receiving IMRT by investigating the association between time course and recovery of TD in both acute and late phases.

Role of vitamin D3 in tumor aggressiveness and radiation response for hepatocellular carcinoma.

Locoregional control is a significant prognostic factor for hepatocellular carcinoma (HCC). Historically, the use of radiotherapy (RT) for HCC was limited owing to the low radiotolerance of the liver and the need for high RT doses for disease control. We aimed to examine if 1α,25-dihydroxyvitamin D3 (calcitriol) has a role in the tumor inhibition and the radiation response of HCC in vitro and in vivo, and explore the underlying mechanisms.

Treatment Strategy for Dialysis Patient with Urothelial Carcinoma.

To investigate postoperative complications and oncologic outcomes of prophylactic nephroureterectomy and/or cystectomy in dialysis patients with urothelial carcinoma (UC), we retrospectively reviewed the records of dialysis patients with UC and a final status of complete urinary tract extirpation (CUTE, i.e., the removal of both kidneys, ureters, and bladder) between January 2004 and December 2015.

Role of Nutritional Status in the Treatment Outcome for Esophageal Squamous Cell Carcinoma.

Undernourishment is reported to impair treatment response, further leading to poor prognosis for cancer patients. We aimed to investigate the role of nutritional status on the prognosis of squamous cell carcinoma (SCC) of the esophagus, and its correlation with anticancer immune responsiveness. We retrospectively reviewed 340 esophageal-SCC patients who completed curative treatment and received a nutrition evaluation by the Patient-Generated Subjective Global Assessment (PGSGA) score at the beginning and completion of neoadjuvant treatment at our hospital.
