Dynamic Risk Prediction of Severe Myelosuppression in Nasopharyngeal Carcinoma

Summary

This multicenter, prospective, observational cohort study aims to evaluate a previously developed dynamic risk prediction model for severe treatment-related myelosuppression in patients with nasopharyngeal carcinoma receiving systemic therapy. The model is designed to estimate the risk of grade 3 or higher anemia, thrombocytopenia, and leukopenia or neutropenia during treatment. Eligible adult patients with histologically confirmed nasopharyngeal carcinoma will be consecutively enrolled at participating centers. Before each cycle of systemic therapy, routinely available clinical and laboratory data will be collected and used to generate updated risk predictions. Patients will be followed throughout systemic therapy and for 28 days after the last treatment. This is an observational study. Treatment and supportive care will be determined by treating physicians according to routine clinical practice. Model predictions will be used only for research evaluation and will not be used to guide or modify patient treatment. The study will evaluate the predictive performance and clinical applicability of the model across multiple centers.

Eligibility

Inclusion Criteria:

* Voluntary provision of written informed consent.
* Age ≥18 years.
* Histologically confirmed nasopharyngeal carcinoma.
* Patients who, in the judgment of the treating physician, require systemic anticancer treatment.

Exclusion Criteria:

* Presence of other uncontrolled serious diseases, including unstable cardiac disease requiring treatment, poorly controlled diabetes mellitus (fasting blood glucose \>1.5 times the upper limit of normal), psychiatric disorders, or a history of severe allergy.
* Considered unsuitable for participation in the study by the investigator.
