Laryngeal cancer

A squamous cell carcinoma of the vocal cords, caused mostly by smoking and alcohol. Hoarseness is the first sign, so it is often found small and cured with the voice kept; left to grow, it can cost the larynx.

Installation

bunx shadcn@4.22.1 add @organui/laryngeal-cancer

This adds laryngeal-cancer.tsx, the disease's data and component, to your components directory. It is built on the disease viewer and reuses the models of the larynx, which install with it.

Usage

import { LaryngealCancer } from "@/components/laryngeal-cancer"

export function LaryngealCancerDemo() {
  return <LaryngealCancer />
}

Every structure is a finding: affected structures are amber and spared ones muted. Select one, in 3D or in the panel, to read what the disease does there.

Course

Set stage or defaultStage to one of these. Each stage changes which structures are affected and the investigations to expect; the timeline under the model shows them in order, with the events along the way.

Early "early" · Weeks of hoarseness
A hoarse voice that does not settle within three weeks, in a smoker in their sixties. There is no pain, lump or difficulty breathing. Radiotherapy or laser surgery cures about nine in ten.
- Nasendoscopy (within 2 weeks): A thin camera through the nose shows the cords in clinic. A biopsy under general anaesthetic confirms the cancer.
- Radiotherapy or laser: Radiotherapy, or removing the cancer with a laser through the mouth; both keep the voice, which radiotherapy often keeps better. Stopping smoking improves the chance of cure.
Affects 1 structure of the larynx.
Fixed cord "fixed-cord" · Months
Left untreated, the cancer grows into the muscle under the cord and above and below it. The cord stops moving, the voice weakens, and the narrowed airway can cause noisy breathing. Chemoradiotherapy can still keep the larynx.
- Chemoradiotherapy: Radiotherapy with cisplatin, to keep the larynx; surgery is kept for a cancer that remains or returns.
Affects 3 structures of the larynx.
Through the cartilage "through-cartilage" · Months later
The cancer breaks through the thyroid cartilage into the neck (T4a), and often reaches the nodes. Radiotherapy alone controls it less well and leaves a poorly working larynx, so the larynx is removed and the patient breathes through a stoma in the neck.
- Total laryngectomy: The larynx is removed with the nodes in the neck, followed by radiotherapy. The trachea opens onto the neck for life, and a valve between the trachea and oesophagus lets the patient speak again.
Affects 4 structures of the larynx.

Without Panel

Hide the panel to place the model in your own layout, and choose the scale and stage with props.

Controlled

Drive the stage, scale and selection from your own state, such as a patient's timeline.
