Gastric cancer with metastases to the scaphoid: a case report

Scaphoid metastasis as the first sign of occult gastroesophageal junction cancer: A case report

BACKGROUND

Metastatic tumors of the hand are very rare. They are usually late manifestations of massive advanced malignancies. However, a small portion of acrometastases are indications of occult primary cancer. Here, we report an extremely rare case in which a scaphoid bone lesion was the initial manifestation and was found to be a metastasis from gastroesophageal junction (GEJ) cancer.

CASE SUMMARY

A 57-year-old male patient presented with ongoing left wrist pain and swelling after trauma. He was initially misdiagnosed with infection of the scaphoid bone and treated with antibiotics and anti-inflammatory drugs. Further radiographic investigations showed a scaphoid pathological fracture, indicating a metastatic tumor derived from the GEJ and/or right lung malignancies. Gastroscopy failed to identify the pathology of the mass at the GEJ, which grew in an exophytic pattern. A lung puncture biopsy was not performed because the patient refused the procedure. To relieve his wrist pain and obtain a definite pathology, we resected the scaphoid lesion. Based on the clinical and pathological results, the patient was finally diagnosed with multiple metastases of advanced GEJ adenocarcinoma. He underwent chemotherapy and died 6 mo after his initial presentation.

CONCLUSION

Despite the rareness of the disease, orthopedic surgeons should consider the possibility of metastasis to the bones of the hand when patients complain of persistent and progressive pain in the hand.

Colon adenocarcinoma with metastases to the scaphoid: a case report and review of the literature

Metastases to the hand and wrist are extremely rare, with <250 cases described in the literature. We present a case of acrometastasis of colon adenocarcinoma to the scaphoid in an 81-year-old male. Adenocarcinoma of the colon metastasizes to bone in an estimated 10% of cases; however, we are unaware of reports of this tumor metastasizing to the scaphoid or to any of the other carpal bones. We were able to identify only two cases of scaphoid metastases in the literature. This case highlights the potential for metastatic disease and other lesions to develop in the scaphoid and carpus.

Long non-coding RNA LINC00978 promotes cell proliferation and tumorigenesis via regulating microRNA-497/NTRK3 axis in gastric cancer

Gastric cancer (GC) is the most common gastrointestinal malignancy in the digestive system. Recent studies have proven that long non-coding RNAs (lncRNAs) are closely related to tumor growth and metastasis. The study aimed to explore the effect of LINC00978 on GC cells proliferation and tumorigenesis. LINC00978 was up-regulated in GC tissues and cell lines. Up-regulation of LINC00978 was positively correlated with low survival rate. LINC00978 silence inhibited proliferation, metastasis, and promoted apoptosis in BGC-823 cells. Additionally, LINC00978 functioned as competing endogenous RNA to inhibit miR-497 expression. Further, NTRK3 was confirmed as a target gene of miR-497. Up-regulation of NTRK3 was found in GC tissues, and the positive correlation was presented between LINC00978 and NTRK3. Further, LINC00978 promoted cell proliferation and tumor weight by regulation of NTRK3. These findings demonstrated that LINC00978 promoted cell proliferation and tumorigenesis by regulating miR-497/NTRK3 axis in GC.
