There are two distinct etiologies of esophago-gastric junctional adenocarcinomas (EGJACs): one associated with extensive gastric mucosal atrophy (GA), resembling non-cardiac gastric cancers; and the other related to gastro-esophageal reflux disease, resembling esophageal adenocarcinoma. In this study, we investigated the associations between the visceral fat area (VFA) and EGJACs separately in the two subtypes of EGJACs, depending on the extent of background GA. Sixty-four consecutive patients with EGJACs (Siewert type 2) were enrolled from a population-based database in Akita Prefecture, Japan, between 2014 and 2019. Two age- and sex-matched healthy controls were randomly assigned to each EGJAC case. The extents of GA were evaluated endoscopically, and the VFA values were measured based on computed tomography images. Logistic regression analyses were performed to investigate the associations between EGJACs and the VFA. Study subjects were classified into 2 subgroups depending on the extent of endoscopic GA: 29 (45.3%) without and 35 (54.7%) with extensive GA. Multivariable regression analyses revealed that a VFA of ≥100 cm2 was significantly associated with EGJACs in subjects without extensive GA [odds ratio (95% confidence interval): 2.65 (1.08–6.54)], while there was no such association in subjects with extensive GA [odds ratio (95% confidence interval): 1.52 (0.60–3.83)]. The contribution of the VFA to the etiology of EGJACs seems to differ depending on the extent of background GA, with the VFA more prominently associated with EGJACs in subjects without extensive GA than in those with it, providing further rationale concerning the heterogeneous nature of EGJAC etiology.

While an association between esophago-gastric junctional adenocarcinomas (EGJACs) and obesity, especially visceral obesity, has been suggested in Western countries, the association remains unclear in Asia, including Japan. In this population-based case-control study, we investigated the association between EGJACs and obesity.To perform near-population-based data collection for all early-stage EGJACs occurring in Akita Prefecture from 2014 to 2019, clinical data, including endoscopic and computed tomography (CT) findings, were collected from 11 cancer treatment base hospitals in the area. Age- and gender-matched controls were extracted at a case-to-control ratio of 1:2 from healthy subjects who received health checkups in the same area. The visceral fat area (VFA) was calculated using CT images. Logistic regression analyses were performed to investigate the associations between EGJACs and obesity-related parameters.In total, 74 EGJAC cases (62 males, median age of 70 years old) and 148 controls were extracted. Multivariable analyses showed a significantly negative association between the BMI and EGJACs and a significantly positive association between the VFA and EGJACs with odds ratios (ORs) (95% confidence intervals [CIs]) of 0.65 (0.53-0.80) and 1.01 (1.01-1.02), respectively. These findings were confirmed in another dataset (40 EGJACs and 80 controls). In addition, as a categorical variable, VFA ≥ 100 cmWe found paradoxical associations between EGJACs and obesity-related parameters (BMI vs. VFA) in a Japanese population, suggesting a potentially pivotal role of the VFA rather than the BMI as a risk factor for EGJACs.

A 73-year-old male underwent lobectomy with ND2a lymph node dissection and resection of the superior vena cava for right lung cancer in December 1998 at Akita University Hospital. Histopathological examination demonstrated moderately differentiated adenocarcinoma (pT4 (SVC) N2M0, Stage IIIB). He received 1 course of a combination of cisplatin (CDDP) and etoposide (ETP) as postoperative adjuvant therapy. In March 2001, he again underwent partial resection of the right lung (S8) due to recurrence. In December 2001, a new left lung metastatic tumor was found. The patient was transferred to our hospital, where he was given 1 course of vinorelbine (NVB) 25 mg/m2 (day 1, 8) and CDDP 80 mg/m2 (day 1). Subsequently, he received 2 courses of vinorelbine (NVB) 25 mg/m2 (day 1, 8) and carboplatin (CBDCA) 430 mg/body (day 1). After the chemotherapy, a complete response (CR) of metastatic lesions was achieved. Adverse reactions were grade 3 neutropenia, grade 2 alopecia and grade 1 nausea/vomiting. The combination of vinorelbine and platinum agent (CDDP/CBDCA) is a useful regimen in treating recurrent non-small-cell lung cancer.
