2018 Leibovich Model for Renal Cell Carcinoma: Comprehensive Explanation and Clinical Context The 2018 Leibovich Model is a postoperative prognostic scoring system designed for patients with clear cell renal cell carcinoma after nephrectomy. It estimates the risk of disease recurrence and long term oncologic outcomes using routinely available histopathologic variables. Definition and Components The model integrates p
PSA ng/mL Gleason Score Select Gleason six Gleason seven Gleason eight to ten Clinical T Stage Select T one or T two a T two b or T two c T three Percent Positive Biopsy Cores CAPRA Prostate Cancer Score Explanation and Clinical Context The CAPRA Score is a validated clinical tool designed to estimate the risk of prostate cancer progression at diagnosis. It incorporates serum PSA concentration the Gleason grading sys
CARG and CRASH calculators explanation and clinical context These two validated tools help clinicians estimate the probability of severe chemotherapy related toxicity in older adults receiving cytotoxic chemotherapy. The CARG model uses eleven pre chemotherapy variables including age at or above 72 years cancer type planned chemotherapy dosing number of chemotherapy drugs patient reported items from a brief geriatric
Explanation and Clinical Context The EORTC risk tables estimate the probability of recurrence and progression for patients with non muscle invasive bladder cancer using six clinical and pathological factors. Each factor is assigned points for recurrence and for progression. The sum of points is translated into a probability at one year and at five years using the published EORTC tables. These predictions can support

Gail Breast Cancer Risk Model Explanation and Clinical Context The Gail Breast Cancer Risk Model is a validated clinical tool developed to estimate the probability that a woman will develop invasive breast cancer over a defined period, usually five years and over a lifetime until age ninety. The model incorporates epidemiologic risk variables including current age, age at menarche, age at first live birth, number of
IPS Prognosis Score Explanation and Clinical Context The International Prognostic Score is a validated tool originally developed to estimate prognosis in patients with advanced Hodgkin lymphoma. Although primarily applied in hematology, the variables included such as albumin, LDH, sodium level, age, white cell count, lymphocyte percentage, and sex represent global markers of systemic illness and physiological reserve
Explanation and Clinical Context This calculator uses the Brock University Model which is one of the most validated prediction tools for estimating the probability of malignancy in pulmonary nodules detected on computed tomography. It integrates clinical variables and radiologic features to produce a numerical estimate of cancer probability that supports decision making in surveillance imaging biopsy or surgical eval

Mantle Cell Lymphoma International Prognostic Index and simplified approach explanation The Mantle Cell Lymphoma International Prognostic Index provides a clinical estimate of prognosis based on four baseline variables age ECOG performance status serum lactate dehydrogenase relative to the laboratory upper limit of normal and white blood cell count measured in 10 to the 9 per liter. The original MIPI score is compute
Milan Criteria for Liver Transplant in Hepatocellular Carcinoma Explanation and Clinical Context The Milan Criteria define a simple morphological selection rule for liver transplant candidacy in patients with hepatocellular carcinoma. The rule is a single tumor with maximum diameter of 5 centimeters or less or up to three tumor nodules with each nodule 3 centimeters or less in diameter. These size and number rules ap
Prostate Cancer Gleason Score Explanation and Clinical Context The Gleason Score is a fundamental grading system for prostate cancer based on the microscopic appearance of tumor glands. The score combines the primary pattern which represents the predominant architectural pattern and the secondary pattern which represents the next most common pattern. The numeric sum reflects tumor aggressiveness and guides prognosis
