Summary
The kOBCS© software reliably estimates Objective Breast Cosmesis Scale (OBCS) values for breast cancer patients, showing strong agreement among users and correlating well with subjective assessments.
Area of Science:
- Oncology
- Medical Imaging
- Biostatistics
Background:
- Breast cancer treatment often involves breast-conserving therapy (BCT).
- Assessing aesthetic outcomes post-BCT is crucial for patient well-being.
- The Objective Breast Cosmesis Scale (OBCS) provides an objective measure of aesthetic changes.
Purpose of the Study:
- To evaluate the kOBCS© software for simplifying OBCS value estimation.
- To determine the reliability and reproducibility of the kOBCS© software.
Main Methods:
- kOBCS© software was used to estimate OBCS values from patient photographs.
- 20 users (experts and non-experts) evaluated 30 patient photos across two settings.
- Comparisons were made with hand measurements and subjective evaluations using the Harvard breast cosmesis scale.
Main Results:
- Highly significant correlation (r=0.997) between kOBCS© and hand-measured OBCS values.
- Strong inter-rater agreement among users of kOBCS© (ICC=0.846).
- Significant correlation (r=0.961) between kOBCS© estimations and subjective assessments.
Conclusions:
- kOBCS© software is a reliable and reproducible tool for reporting breast cosmesis.
- The software simplifies the objective assessment of aesthetic outcomes after breast cancer treatment.
- kOBCS© facilitates consistent reporting of breast cosmesis following breast-conserving therapy.

37.5K
The equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these concentrations are known, the calculation simply involves their substitution into the Kc expression.
For example, gaseous nitrogen dioxide forms dinitrogen tetroxide according to this equation:

24.7K
The free energy change for a reaction that occurs under the standard conditions of 1 bar pressure and at 298 K is called the standard free energy change. Since free energy is a state function, its value depends only on the conditions of the initial and final states of the system. A convenient and common approach to the calculation of free energy changes for physical and chemical reactions is by use of widely available compilations of standard state thermodynamic data. One method involves the...

A buffer can prevent a sudden drop or increase in the pH of a solution after the addition of a strong acid or base up to its buffering capacity; however, such addition of a strong acid or base does result in the slight pH change of the solution. The small pH change can be calculated by determining the resulting change in the concentration of buffer components, i.e., a weak acid and its conjugate base or vice versa. The concentrations obtained using these stoichiometric calculations can be used...

Hydronium and hydroxide ions are present both in pure water and in all aqueous solutions, and their concentrations are inversely proportional as determined by the ion product of water (Kw). The concentrations of these ions in a solution are often critical determinants of the solution’s properties and the chemical behaviors of its other solutes. Two different solutions can differ in their hydronium or hydroxide ion concentrations by a million, billion, or even trillion times. A common means of...

When a mechanic tries to remove a hex nut with a wrench, it is easier if the force is applied at the farthest end of the wrench handle. The lever arm is the distance from the pivot point (the hex nut in this case) to the person’s hand. If this distance is large, the torque is higher. Only the component of the force perpendicular to the lever arm contributes to the torque. Therefore, pushing the wrench perpendicular to the lever arm is more advantageous. If multiple people apply force to...
