Surgical Outcomes for Ovarian Cancer in Older Adults in Japan, 2004-2018

1,365 patient records from the Osaka Cancer Registry for women aged 70 and older diagnosed with epithelial ovarian cancer between 2004 and 2018. The data includes surgical outcomes, disease extent, chemotherapy data, and overall survival rates. The study was authored by Tsuyoshi Hisa and published on figshare.

Use Cases

• Analyze temporal trends in surgical management based on the reported shift in non-surgical treatment over time.
• Model survival outcomes based on surgical outcome categories like complete resection or residual tumor.
• Investigate treatment patterns for advanced disease based on the described categorization of disease extent.
• Assess the prognostic impact of surgical resection based on the reported hazard ratios for mortality.

Strengths

• Population-based data from the Osaka Cancer Registry covering 10,033 women diagnosed with ovarian cancer.
• Longitudinal coverage spanning 15 years from 2004 to 2018.
• Specific 5-year survival rates reported for different surgical outcomes: 63.9%, 27.9%, and 9.9%.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes residual confounding is possible due to unavailable comorbidity and frailty data.
