ABSTRACT
BACKGROUND/AIM: Osteopenia, the loss of bone mineral density (BMD), was recently reported as a prognostic factor in various cancers. However, the prognostic significance of preoperative osteopenia in breast cancer remains unclear. This study aimed to clarify the clinical significance of preoperative osteopenia in breast cancer. PATIENTS AND METHODS: We retrospectively analyzed the relationship between osteopenia and clinical factors and prognosis in 532 patients with pathological Stage I-III primary breast cancer between 2009 and 2017. Osteopenia was assessed by measuring the average pixel density (Hounsfield unit) in the midvertebral core of the 11th thoracic vertebra on enhanced preoperative computed tomography. RESULTS: Osteopenia was diagnosed in 186 (35.0%) patients. The recurrence-free survival (RFS) rate was significantly worse in the osteopenia group than in the non-osteopenia group (p=0.0275), but there was no significant difference in overall survival (OS) between the two groups. When evaluated by menopausal status, RFS and OS were significantly worse in the osteopenia group than in the non-osteopenia group (p=0.0094 and p=0.0264, respectively) in premenopausal patients. However, there were no significant differences in RFS and OS between the two groups among postmenopausal patients. In premenopausal patients, osteopenia was an independent prognostic factor for RFS in a multivariate analysis (p=0.0266). CONCLUSION: Preoperative osteopenia was independently associated with recurrence of breast cancer.

BACKGROUND: Intramural metastasis (IM) of esophageal cancer is classified as distant metastasis according to the Japanese Classification of Esophageal Cancer, and it is well-known to be associated with a poor prognosis. We herein report a case of perforated gastric IM of esophageal cancer that was successfully controlled with nonradical surgery and subsequent immune checkpoint inhibitor (ICI) treatment. CASE PRESENTATION: A 72-year-old woman was referred to our department for the treatment of esophageal cancer and perforated gastric ulcer. A histological examination of the main tumor and gastric ulcer lesion revealed squamous cell carcinoma. Since the gastric wall tumor had invaded the celiac artery, complete resection was considered impossible. Chemotherapy was administered but led to severe adverse events, so palliative resection was performed. Two months after surgery, computed tomography revealed enlargement of the residual tumor around the celiac artery. However, after nivolumab monotherapy was started, the tumor diminished remarkably, and the quality of life of the patient dramatically improved. Nine months after nonradical surgery, she is surviving without any disease concern. CONCLUSIONS: With the increased availability of ICIs, multidisciplinary treatment with surgery and ICIs can potentially lead to long-term survival, even in cases expected to have a poor prognosis.
