Epidemiology of Gynecological Malignancies in Uniosun Teaching Hospital Osogbo Nigeria: A Five-Year Retrospective Review
This five-year retrospective review at UNIOSUN Teaching Hospital in Osogbo, Nigeria, reveals that cervical cancer is the most prevalent gynecological malignancy (44.3%), while ovarian cancer contributes disproportionately to mortality, underscoring the urgent need for enhanced screening, vaccination, and early referral programs in resource-limited settings.

Imagine the human body as a bustling city, where every organ is a neighborhood with its own rules and rhythms. Sometimes, however, a neighborhood gets overrun by a chaotic, uninvited construction crew that builds structures it shouldn't, ignoring all the traffic lights and safety codes. In the medical world, this is called a malignancy, or cancer. When this happens in the female reproductive system—the "reproductive district" of the body—it's known as gynecological malignancy. Think of this district as having several key buildings: the cervix (the gateway), the ovaries (the egg factories), the uterus (the nursery), and the vagina (the exit tunnel).
For a long time, scientists have known that while some cities (countries) have built excellent security systems to catch these construction crews early, others struggle to even see them until the damage is done. This is especially true in places with fewer resources, where screening programs are scarce and access to treatment is like trying to find a specific street in a city without a map. The big question researchers ask is: "What does the chaos look like in our specific neighborhood?" Is it mostly the gateway getting overrun? Are the egg factories under attack? And when the city tries to fight back with surgery or medicine, does it work? Understanding the local pattern is like having a detailed map of the trouble spots; it helps city planners (doctors and policymakers) know where to send their firefighters and where to build new walls.
The Map of the Trouble Spots
In this study, a team of researchers from the Osun State University Teaching Hospital (UTH) in Osogbo, Nigeria, decided to take a deep dive into their own medical records. They acted like detectives looking back through a five-year time capsule, from August 1, 2020, to September 30, 2025. They wanted to see what was happening in their "reproductive district" during that time. They sifted through the files of 3,000 patients who came in for gynecological issues and found that 131 of them were dealing with a malignancy. That means about 4.4% of the patients they saw had this specific type of trouble.
Who is getting hit, and where?
When the researchers looked at the "construction crews" causing the trouble, they found a clear leader. Cervical cancer was the most common villain, showing up in 58 cases (44.3%). It was the big boss of the group. Right behind it was ovarian cancer, which appeared in 37 cases (28.2%). Then came choriocarcinoma (a rare type of cancer related to pregnancy) with 24 cases (18.3%), followed by endometrial cancer (affecting the uterus lining) with 11 cases (8.4%), and a single, lonely case of vaginal cancer (0.8%). Interestingly, they didn't find any cases of vulva or fallopian tube tumors in their records.
The researchers also noticed that the "construction crews" seemed to target specific age groups. The gateway (cervix) was mostly attacked by women aged 45 and older, with 93.1% of those cases happening in that older group. In fact, they found zero cases in women under 35. The egg factories (ovaries) were a bit more flexible, attacking all ages, but they hit the 55-and-up group the hardest. The uterus lining (endometrium) was strictly a senior citizen's problem in this study, with 100% of those cases happening in women 55 and older. On the flip side, the pregnancy-related trouble (choriocarcinoma) was a young person's issue, striking women under 45 in 95.8% of the cases.
They also looked at how many children the women had (a concept called parity). It turned out that the gateway (cervix) was most often attacked by women who had five or more children. The egg factories (ovaries) and the pregnancy-related trouble (choriocarcinoma) seemed to prefer women with fewer children (0 to 2).
How the City Fought Back
Once the trouble was spotted, the city had to decide how to fight it. The researchers saw that the most common weapon used was chemoradiation (a mix of medicine and radiation beams), which was the primary treatment for 58 patients (44.2%). Another 40 patients (30.5%) got a combination of surgery and chemotherapy. Some got just chemotherapy (18.5%) or just surgery (6.8%).
The outcome of these battles was recorded at the end of the review period. Out of the 131 patients, 104 (79.4%) were still alive, while 27 (20.6%) had passed away. The researchers noted that ovarian cancer was responsible for the majority of the deaths, followed by cervical and endometrial cancers. This suggests that while the city was winning most battles, the fight against ovarian cancer was particularly tough.
What the Researchers Think
The authors suggest that the high number of cervical cancer cases confirms that this remains a major public health challenge in their region, likely because many women don't get screened early enough. They also point out that the high number of choriocarcinoma cases (which is usually rare) might be because people aren't getting early prenatal care, leading to delayed diagnoses of pregnancy-related issues.
The study concludes that to win this war, the city needs better maps and more firefighters. They recommend strengthening cervical cancer screening, rolling out HPV vaccination programs (which act like a vaccine against the virus that causes the trouble), and making sure people know when to seek help early. They also suggest that doctors should be extra careful checking any pregnancy-related tissue to catch trouble before it turns into a malignancy.
While this study gives a clear picture of what happened in Osogbo over five years, the authors admit it's just one city's story. They can't say for sure if this is exactly what's happening in every other town in Nigeria, but it provides a crucial snapshot for planning how to protect the "reproductive district" in the future.
