Distribution analysis of gynecological carcinomas with concurrent second primary carcinomas

Area of Science:

• Gynecology
• Oncology
• Cancer Research

Background:

• Cervical carcinoma (CC) and endometrial carcinoma (EC) are significant gynecological malignancies.
• Second primary carcinoma (SPC) is a concern in patients with initial gynecological cancers.
• Identifying SPC patterns can improve patient outcomes and monitoring strategies.

Purpose of the Study:

• To investigate the distribution, timing, and clinicopathological correlations of SPC in patients with CC and EC.
• To guide precise monitoring protocols for SPC in these patient populations.

Main Methods:

• Retrospective analysis of 253 CC patients and 102 EC patients diagnosed with SPC.
• Descriptive statistical methods for patient demographics, latency, and clinicopathological characteristics.
• Spatial distribution analysis of SPC anatomical sites.

Main Results:

• Median age at initial diagnosis for CC and EC was 52 and 55 years; SPC median ages were 56 and 57.5 years.
• Common SPC sites for CC: lung (25.3%), thyroid (22.5%), breast (11.1%). Common SPC sites for EC: thyroid (20.6%), ovary (16.7%), cervix (15.7%).
• Most SPCs in both CC and EC patients were diagnosed at early stages (I-II).

Conclusions:

• SPC occurrence in CC and EC patients exhibits distinct patterns influenced by pathological types.
• These findings offer critical insights for re-evaluating CC and EC patients.
• Enables earlier and more precise detection of SPC in high-risk individuals.
