To build a robust web client for your digital pathology pipeline, you need to transition from a simple "uploader" to an **Image Management System (IMS)** that supports clinical workflows.

Because your project involves sensitive patient data (age, sex, smoking history, survival) and high-resolution medical images, **Authentication (Auth) is not optional—it is a regulatory requirement**.

### 1. Security & Compliance (The "Must-Haves")

In a medical context, you are likely handling **Protected Health Information (PHI)**.

* **Authentication & Authorization:** You need Role-Based Access Control (RBAC).
* *Pathologist:* Can upload slides and validate segmentation.
* *Researcher:* Can view anonymized statistics and survival scores.
* *Admin:* Manages users and system logs.


* **Audit Logging:** You must track every time a patient's record or slide is viewed, edited, or deleted to comply with HIPAA/GDPR.
* **Data De-identification:** A feature to automatically strip patient names from metadata during upload, linking them only via a secure internal ID.

### 2. High-Resolution Whole Slide Image (WSI) Viewer

Standard image tags (`<img>`) cannot handle the size of these files ( per slide). You need a specialized viewer like **OpenSeadragon** or **ASAP**.

* **Pyramidal Zooming:** Allows users to pan and zoom through the slide without loading the entire multi-gigabyte file at once.
* **Digital Micro-Dissection Overlays:** Based on your PDF, the web client should toggle overlays for:
* The **Nucleus**, **Cytoplasm**, and **Membrane** outlines (Segmentation).
* Heatmaps showing **PD-L1 positivity** in different zones.
* Spatial geography markers (e.g., proximity of CD8+ lymphocytes to PD-L1+ cells).


* **Side-by-Side Comparison:** Compare the raw H&E stain with the digital analysis or compare two different patients.

### 3. Workflow & Data Management

* **Batch Upload & QC Dashboard:** A screen to upload ~300 slides and clinical data. It should flag slides that fail the **Automated Quality Control** (e.g., <20% usable tissue or blur) so the user can exclude them immediately.
* **Clinical Data Entry/Import:** A form or CSV importer for the "Inputs" mentioned in your PDF: age, stage, smoking history, and driver mutations (EGFR, ALK, KRAS).
* **Annotation Tools:** Allow pathologists to manually correct the "Digital Pathologist" software if a cell was incorrectly segmented.

---

### 4. Results & Analytics

* **Statistical Risk Dashboard:** Instead of just showing one slide, show the **Prognostic Score** (Overall Survival) and **Predictive Score** (Immunotherapy response probability) for the entire cohort or a specific patient.
* **Interactive Kaplan-Meier Curves:** A graph that updates based on the intracellular PD-L1 data, allowing users to filter by "High vs. Low" expression levels.
* **Export Reports:** Generate a PDF report for a specific patient that summarizes their PD-L1 status across all three cellular zones.
