Accuracy of determining sarcopenia using SARC-CalF in community-dwelling older adults aged 75 years and older.

OBJECTIVE: The accuracy of sarcopenia determination using SARC-CalF in community-dwelling older adults has been clarified in previous studies. However, this accuracy is unknown for subjects older than 75 years old. If this becomes clear, it will show the usefulness of using SARC-CalF in determining sarcopenia in community-dwelling older adults aged ≥75 years old. Thus, this study aimed to investigate the accuracy of sarcopenia determination using SARC-CalF in community-dwelling older adults aged ≥75 years old. METHODS: This study included 102 older adults aged ≥75 years old (74.5% female). Subjects were provided outpatient rehabilitation one to three times a week. The Asia Working Group for Sarcopenia 2019 standard was used to determine sarcopenia in participants. Logistic regression analysis was performed with sarcopenia as the dependent variable, and age, sex, and SARC-CalF as independent variables. When SARC-CalF was extracted as a significant variable, a receiver operating characteristic (ROC) curve was created. The cut-off value was calculated using the Youden index. RESULTS: Sarcopenia was observed in 65 of 102 subjects. Logistic regression analysis showed that only SARC-CalF was extracted as a significant variable (odds ratio: 1.18 [95% CI: 1.09-1.29]). The cut-off value calculated from the ROC curve was seven points. The sensitivity and specificity were 94.7% and 92.3%, respectively, and the area under the curve was 0.98. CONCLUSIONS: Our results indicate that SARC-CalF can accurately determine sarcopenia in older adults. A SARC-Calf cut-off value of seven may be more useful than 11 in determining sarcopenia in community-dwelling older adults aged ≥75 years old.

Metachronous primary cancer of the tongue and malignant lymphoma of the small intestine: A case report.

RATIONALE: Oral cancer often causes secondary primary cancers in the upper gastrointestinal tract. However, there are no reports of secondary primary cancers in patients with oral squamous cell carcinoma and malignant lymphoma of the small intestine. This report describes a case of metachronous multiple primary cancers of the tongue and small intestine malignant lymphoma. PATIENTS CONCERNS: The patient was admitted to our department with the chief complaint of pain in the right tongue. Partial tongue resection and supraomohyoid neck dissection were performed. One year after surgery, the patient experienced abdominal pain and bloody stools. DIAGNOSIS: Diffuse large B-cell lymphoma (DLBCL) was diagnosed via histological examination. INTERVENTIONS: A terminal ileum resection was performed. Postoperatively, the patient received 6 courses of rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone (R-CHOP). OUTCOMES: Five years after his initial diagnosis, there is no evidence of recurrence, metastasis, or other primary cancer. LESSONS: Oral cancer patients should always be followed up owing to a possibility of malignant tumors in other areas.
