Oncology Toolkit
These tools are designed to support clinical workflow in radiation oncology
and general medical practice, providing quick access to diagnostic codes
and calculation utilities used in day-to-day charting and patient management.
Tools
-
ICD-10 Code Search — Fast full-text lookup of ICD-10
diagnostic codes with specialized filtering for oncology and radiation therapy
indications, including an IMRT-focused subset.
-
PSA Doubling Time Calculator — Calculates PSA doubling
time from serial PSA measurements using weighted least-squares exponential
fitting. Accepts flexible date and value input formats, plots an interactive
growth curve projected five years forward, and allows date-point querying
directly on the graph.
-
BED / EQD2 Calculator — Computes Biologically Effective
Dose and Equivalent Dose in 2 Gy fractions for a given prescription across
configurable α/β tissue values (Tumor, Late, Prostate/Spine). An
alternative fractionation section converts the same BED to isoeffective total
doses for 1, 3, 5, and any arbitrary number of fractions. Based on a spreadsheet
by Dr. Mike Wahl.
-
Composite Dose Calculator — Estimates the remaining
tolerable dose to a previously irradiated structure. Takes structure tolerance
dose/fractions/αβ, a prior dose with optional time discount factor,
and a planned fraction count to compute the remaining safe dose and dose per
fraction. Based on a spreadsheet by Dr. Mike Wahl.
-
Reirradiation Dose Calculator — Estimates remaining
organ-at-risk dose tolerance for reirradiation cases using UMich ReRT guidelines.
Accepts prior plan fractionation, α/β, and time since prior RT.
OARs are selected from a checklist of 24 serial and parallel structures;
each displays the prior physical dose converted to EQD2, tissue recovery factor
(TRF) columns for all documented time intervals with the active bucket highlighted,
and a results table showing remaining EQD2 and isoeffective physical doses
for 1, 3, 5, and a custom number of fractions — all updating in real time.
