Combined radiotherapy and chemotherapy is considered the standard of care for locally advanced nasopharyngeal carcinoma (LA-NPC) in Epstein-Barr virus infection endemic area. This study compared the long-term outcomes between LA-NPC patients treated with neoadjuvant chemotherapy followed by radiotherapy (NACT) and those treated with concurrent(More)
Individuals with allergies have a heightened Th2 (T helper 2) immunity, which may provide advantages in controlling tumor growth. Inverse associations have been reported among individuals with allergies and risk of brain and pancreatic cancers. We examined the relationship between allergies and risk of head and neck squamous cell carcinoma (HNSCC) in a(More)
BACKGROUND The current study evaluated the association between tea consumption and head and neck cancer (HNC) in Taiwan, where tea is a major agricultural product and a popular beverage. METHODS Interviews regarding tea consumption (frequency, duration, and types) were conducted with 396 HNC cases and 413 controls. Unconditional logistic regression was(More)
Owing to the high mortality and rapidly growing costs related to lung cancer, it is worth examining the health benefits of prevention for major types of lung cancer. This study attempts to quantify the quality-adjusted life expectancy (QALE), loss-of-QALE, and lifetime healthcare expenditures of patients with different pathological types of lung cancer. A(More)
This analysis evaluated the association between serum retinol levels and risk of head and neck cancer (HNC) and whether the association is modulated by the use of alcohol, betel quid, or cigarette. In addition, we also examined the association between HNC risk and 2 single nucleotide polymorphisms, TTR rs1667255 and RBP4 rs10882272, that have been(More)
Allergy symptoms have been associated with a reduced head and neck cancer (HNC) risk, while elevated blood immunoglobulin E (IgE) levels have been associated with an increased HNC risk. According to the “prophylaxis hypothesis,” allergic reaction is the body’s way of expelling carcinogens. IgE level may be increased by exposure to environmental carcinogens,(More)
OBJECTIVES Host immunity likely plays a role in preventing progression of diffuse large B-cell lymphoma (DLBCL). Analysis of host immune cells may provide useful information for assessing prognosis or possibly clinical management. METHODS Peripheral blood samples from 77 patients with DLBCL and 30 healthy volunteers were analyzed using flow cytometry(More)
BACKGROUND Although substantial evidence supports a 20-30% risk reduction of colon cancer, breast cancer, and endometrial cancer by physical activity (PA), the evidence for head and neck cancer (HNC) is limited. Three published studies on the association between PA and HNC have generated inconsistent results. The current study examined the association(More)
OBJECTIVES Although betel quid (BQ) is an established risk factor of head and neck cancer (HNC), insufficiencies exist in the literature regarding the dose-response, BQ types, HNC sites, and BQ cessation. The current study was conducted to fill these insufficiencies. MATERIALS AND METHODS A hospital-based case-control study was conducted to evaluate the(More)
