TLDR
It was determined that underweight and obesity-compared with normal weight-were significantly associated with 73% increased risk and 30% decreased risk of EC, respectively, and achieving normal range of BMI could reduce the risk of ESCC.
Abstract
Objective: In Korea, 95% of esophageal cancer (EC) was the squamous cell-type. We sought to determine the combined risk of alcohol consumption on developing esophageal squamous cell carcinoma (ESCC) in pre-diagnostic underweight subjects using Korean national data. Methods: We analyzed the clinical data from a total of 264,084 individuals aged 40 years or older, who received healthcare checkups arranged by the national insurance program, between 2003 and 2008 in Korea. Cox proportional hazards regression was used after adjusting confounding factors. Result: Newly diagnosed 278 EC was identified using the claims data during a median follow-up duration of 7.9 years. It was determined that underweight and obesity-compared with normal weight-were significantly associated with 73% increased risk and 30% decreased risk of EC, respectively. Weight gain reduced the risk of EC. Alcohol consumption increased risk for EC in a dose-dependent manner. Heavy alcohol consumption in individuals with underweight increased the risk of developing EC dramatically. Conclusion: Underweight was a risk factor for ESCC and alcohol consumption raised the risk synergistically with low BMI. Achieving normal range of BMI could reduce the risk of ESCC.

Cumulative evidence for the relationship between body mass index and the risk of esophageal cancer: An updated meta-analysis with evidence from 25 observational studies.

TL;DR: A large number of papers reporting the relationships between body mass index (BMI) and esophageal cancer risk have been published in the past few decades; however, these results are inconsistent.

Clinical significance of tumor necrosis factor receptor 2 in middle and lower thoracic esophageal squamous cell carcinoma.

TL;DR: The results suggest that TNFR2 can play an important role in the progression and poor prognosis of ESCC patients, and the role ofTNFR2 in the prog outlook of middle thoracic ES CC patients was earlier and stronger than in lower thoraco-ESCC patients.

Body-mass index and cause-specific mortality in 900 000 adults: collaborative analyses of 57 prospective studies

TL;DR: Below the range 22.5-25 kg/m(2), BMI was associated inversely with overall mortality, mainly because of strong inverse associations with respiratory disease and lung cancer, despite cigarette consumption per smoker varying little with BMI.

TL;DR: Increasing body mass index is associated with a significant increase in the risk of cancer for 10 out of 17 specific types examined, and for colorectal cancer, malignant melanoma, breast cancer, and endometrial cancer, the effect ofBody mass index on risk differed significantly according to menopausal status.
