# Biomarker_NLP
This package (biomarker_nlp) contains modules and functions supporting recognition and extraction of biomarkers for each FDA-approved targeted cancer therapy listed at [NIH National Cancer Institute (NCI)](https://www.cancer.gov/about-cancer/treatment/types/targeted-therapies/targeted-therapies-fact-sheet) from the biomedical text on its NCI webpage (eg https://www.cancer.gov/about-cancer/treatment/drugs/lanreotideacetate) and corresponding DailyMed webpage(s) (eg https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=6e4a41fd-a753-4362-87ee-8cc56ed3660d). The package can extract the following biomarkers: gene/protein; therapy; disease; drug label; NDC code; other drugs in approved combination therapies with selected drug; genes/proteins that, when altered, serve as biomarkers of resistance (via statements of negation, indicating that a drug should not be given for a specific biomarker); whether approval was accelerated (indicating lower evidence threshold and requirement for further confirmatory studies); whether the drug is indicated for first-line treatment; and whether the drug is indicated for metastatic disease.
The biomarker recognition tasks are based on the pre-trained named-entity recognition (NER) models from [scispacy](https://github.com/allenai/scispacy). The tasks for detecting negated biomarkers are based on two pre-trained negation models obtained from Aditya Khandelwal & Suraj Sawant's (2020) [NegBERT](https://github.com/adityak6798/Transformers-For-Negation-and-Speculation) program. The negation tasks include negation cue detection and negation scope extraction from sentences. The package also provides functions to detect key clinical terminology for specific drugs and diseases, such as first-line treatment, accelerated approval, and metastatic disease.
## Installation
To install the library, run command (If you’re in a Colab notebook (or similar), add a ! at the beginning, e.g. !pip):
```bash
pip install biomarker_nlp
```
Some functions will require you to install scispacy pre-trained models. To install a model, run a command like:
```bash
pip install https://s3-us-west-2.amazonaws.com/ai2-s2-scispacy/releases/v0.3.0/en_ner_craft_md-0.3.0.tar.gz
```
Some functions will require pre-trained negation models. Download [negCue](https://www.dropbox.com/s/3b8zhldmrx9niv4/negCue.zip?dl=0) and [negScope](https://www.dropbox.com/s/7nn1uptrvw66mn2/negScope.zip?dl=0), then load them in script:
```python
>>> modelCue = torch.load('/path/to/the/model') # path to the location where the model file is placed
```
#### Example Usage (biomarkers detection)
Install necessary packages and pre-trained models:
```bash
pip install scispacy
pip install -U spacy==2.3.1 # may return incompatible ERROR, but it won't be a problem as long as the spacy-2.3.1 is successfully installed
pip install https://s3-us-west-2.amazonaws.com/ai2-s2-scispacy/releases/v0.3.0/en_ner_craft_md-0.3.0.tar.gz
pip install https://s3-us-west-2.amazonaws.com/ai2-s2-scispacy/releases/v0.3.0/en_ner_jnlpba_md-0.3.0.tar.gz
pip install https://s3-us-west-2.amazonaws.com/ai2-s2-scispacy/releases/v0.3.0/en_ner_bionlp13cg_md-0.3.0.tar.gz
```

#### Example Usage (negation detection)
The negation detection models require NVIDIA GPU, so either make sure your machine has an NVIDIA GPU, or turn the Hardware accelerator GPU on if using Google Colab.
To apply the two negation detection models, you will first want to download them, [negCue](https://www.dropbox.com/s/3b8zhldmrx9niv4/negCue.zip?dl=0) and [negScope](https://www.dropbox.com/s/7nn1uptrvw66mn2/negScope.zip?dl=0), to your local computer from Dropbox. They are in zip format. You do not need to have a Dropbox account to download. Then, load them using the following codes.
Install necessary packages:
```bash
pip install biomarker_nlp
pip install transformers
pip install knockknock==0.1.7
pip install sentencepiece
```
Load the necessary packages and the pre-trained negation detection models:
```python
>>> from biomarker_nlp import negation_cue_scope
>>> from biomarker_nlp.negation_negbert import * # This code MUST be run before loading the pre-trained negation models
>>> modelCue = torch.load('/path/to/negation/cue/detection/model') # path to the location where the model file is placed
>>> modelScope = torch.load('/path/to/negation/scope/detection/model') # path to the location where the model file is placed
>>> txt = "KEYTRUDA is not recommended for treatment of patients with PMBCL who require urgent cytoreductive therapy."
# detect negation cue
>>> negation_cue_scope.negation_detect(text = txt, modelCue = modelCue)
True
# extract the negation scope
>>> negation_cue_scope.negation_scope(text = txt, modelCue = modelCue, modelScope = modelScope)
['KEYTRUDA is', 'recommended for treatment of patients with PMBCL who']
```
