Abstract

Introduction

The present study aims to examine the completeness and model the exhaustiveness of clinical records of cancer patients followed at the Ngaliema Clinic in Kinshasa.

Materials and methods

A retrospective study analyzed the records of 81 patients with cancer followed at the Ngaliema clinic between 2023 and 2025. Using JASP 0.95.4.0 software, descriptive and inferential analyses based on the Little, Friedman, Durbin -Conover test and a multiple linear regression model were performed at the usual threshold of 0.05.

Results

There was a predominance of women and patients under 50 years of age, mostly residing in the Lukunga district, with cancer diagnosed at an invasive stage (stage II) among the patients whose records were analyzed. The MCAR hypothesis was verified (p = 0.767). A significant difference was observed between the five evaluated recording domains ( χ² = 135; p < 0.001). Furthermore, the overall completeness score decreases significantly according to age (β = -0.174; p = 0.016); bilateral organ involvement (β = -7.349; p = 0.029); year of detection 2024 vs 2025 (β = -10.732; p < 0.001); non-invasive nature of the disease (β = -5.893; p = 0.047); family history of cancer (β = -4.491; p = 0.028); of residence in the Funa district vs. Lukunga (β = -4.547; p = 0.017) and of initial traditional treatment/prayer (β = -5.822 ; p = 0.025). However, this score increases with the time elapsed before consultation (β = 0.476 ; p < 0.001) and then with origin from the Tshangu district (β = 9.236 ; p = 0.009).

Conclusion

The completeness of cancer records at the Ngaliema Clinic depends markedly on clinical severity, patient age, and therapeutic pathway. 

Recommendation

Implement a standardized oncology form, strengthen digital skills, support digitization and develop a sustainable provincial cancer registry.
