METHODS FOR PREDICTING CLINICAL IMPLICATIONS IN BREAST CANCER PATIENTS BASED ON TUMOR INFILTRATING LEUKOCYTES FRACTAL GEOMETRY

TECHNICAL FIELD

Disclosed herein are systems and methods based on tumor infiltrating leukocyte (TIL) fractal geometry to predict clinical implications in breast cancer samples. Using machine learning techniques, an algorithmic classifier is constructed and trained on a cohort of tumor images (e.g. radiographic images, H&E images, immunohistochemical (IHC) images) to discriminate between TILs and cancer cells, and breast cancer samples are then classified based on TIL fractal geometry/anatomic distribution.

BACKGROUND

The following description of the background of the present technology is provided simply as an aid in understanding the present technology and is not admitted to describe or constitute prior art to the present technology.

The fractal geometry implicit in nature illuminates many otherwise obscure relationships.¹A natural phenomenon of interest in this regard is the infiltration of cancers with leukocytes, the effectors of the immune system. While in breast cancer the presence of tumor-infiltrating leukocytes (TILs) conveys prognostic and predictive information, the mechanisms remain conjectural.²Nevertheless, this phenomenon may have important implications with respect to immune-directed therapy.³Accordingly, theoretic considerations have focused largely on potentially manipulatable viability-related interactions-both positive and negative-between the cancer cells and the TILs.⁴Useful, but complex, computationally intensive, and often non-intuitive (i.e. computer machine learning) approaches to this subject have been proposed.⁵

SUMMARY OF THE PRESENT TECHNOLOGY

In one aspect, the present disclosure provides a method for predicting prognosis in a breast cancer patient comprising applying, by a computing system having one or more processors, a trained model to detect and quantify (a) cancer cells and (b) tumor-infiltrating leukocytes (TILs) in a biomedical image of a resected tumor sample including a tumor stromal region, wherein the resected tumor sample is obtained from the breast cancer patient; computing a fractal-geometric metric based on anatomic distribution of the TILs in the biomedical image of the resected tumor sample; and determining that the breast cancer patient has a favorable prognosis when the fractal-geometric metric falls below a predetermined threshold, or determining that the breast cancer patient has a negative prognosis when the fractal-geometric metric is at or above a predetermined threshold. In some embodiments, negative prognosis comprises recurrent disease in breast tissue, bone tissue, or brain tissue. Additionally or alternatively, in some embodiments, the method further comprises providing a cancer therapy recommendation based on the fractal-geometric metric, and/or administering a cancer therapy to the breast cancer patient based on the fractal-geometric metric.

FIG. 1B is a block diagram depicting a cloud computing environment comprising client device in communication with cloud service providers.

FIGS. 1C and 1D are block diagrams depicting embodiments of computing devices useful in connection with the methods and systems described herein.

DETAILED DESCRIPTION

It is to be appreciated that certain aspects, modes, embodiments, variations and features of the present methods are described below in various levels of detail in order to provide a substantial understanding of the present technology. It is to be understood that the present disclosure is not limited to particular uses, methods, reagents, compounds, compositions or biological systems, which can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.

The present disclosure is directed to the application of leukocyte-cancer fractal geometry to determine fundamental aspects of tumor initiation and growth. To complement existing computer machine learning approaches, the present disclosure provides a metric with several characteristics: simplicity, ease of assessment, clinical relevance, and interpretability. Fractal geometry appears to be germane in that cancers grow by an iterative process and are hence anatomically irregular but with the same degree of irregularity on all scales. If leukocyte distribution reflects this growth pattern, then the number of leukocytes in a microscopic area should be proportional to the length of that area raised to a power expressing the dimensionality of the process.⁶

Definitions

Unless defined otherwise, all technical and scientific terms used herein generally have the same meaning as commonly understood by one of ordinary skill in the art to which this technology belongs. As used in this specification and the appended claims, the singular forms “a”, “an” and “the” include plural referents unless the content clearly dictates otherwise. For example, reference to “a cell” includes a combination of two or more cells, and the like. Generally, the nomenclature used herein and the laboratory procedures in cell culture, molecular genetics, organic chemistry, analytical chemistry and nucleic acid chemistry and hybridization described below are those well-known and commonly employed in the art.

As used herein, the term “about” in reference to a number is generally taken to include numbers that fall within a range of 1%, 5%, or 10% in either direction (greater than or less than) of the number unless otherwise stated or otherwise evident from the context (except where such number would be less than 0% or exceed 100% of a possible value).

As used herein, the “administration” of an agent or drug to a subject includes any route of introducing or delivering to a subject a compound to perform its intended function. Administration can be carried out by any suitable route, including but not limited to, orally, intranasally, parenterally (intravenously, intramuscularly, intraperitoneally, or subcutaneously), rectally, intrathecally, intratumorally or topically. Administration includes self-administration and the administration by another.

The terms “cancer” or “tumor” are used interchangeably and refer to the presence of cells possessing characteristics typical of cancer-causing cells, such as uncontrolled proliferation, immortality, metastatic potential, rapid growth and proliferation rate, and certain characteristic morphological features. Cancer cells are often in the form of a tumor, but such cells can exist alone within an animal, or can be a non-tumorigenic cancer cell. As used herein, the term “cancer” includes premalignant, as well as malignant cancers. In some embodiments, the cancer is colorectal cancer, lung cancer, breast cancer, ovarian cancer, uterine cancer, or thyroid cancer.

As used herein, a “control” is an alternative sample used in an experiment for comparison purpose. A control can be “positive” or “negative.” For example, where the purpose of the experiment is to determine a correlation of the efficacy of a therapeutic agent for the treatment for a particular type of disease, a positive control (a compound or composition known to exhibit the desired therapeutic effect) and a negative control (a subject or a sample that does not receive the therapy or receives a placebo) are typically employed.

As used herein, the term “effective amount” refers to a quantity sufficient to achieve a desired therapeutic and/or prophylactic effect, e.g., an amount which results in the prevention of, or a decrease in a disease or condition described herein or one or more signs or symptoms associated with a disease or condition described herein. In the context of therapeutic or prophylactic applications, the amount of a composition administered to the subject will vary depending on the composition, the degree, type, and severity of the disease and on the characteristics of the individual, such as general health, age, sex, body weight and tolerance to drugs. The skilled artisan will be able to determine appropriate dosages depending on these and other factors. The compositions can also be administered in combination with one or more additional therapeutic compounds. In the methods described herein, the therapeutic compositions may be administered to a subject having one or more signs or symptoms of a disease or condition described herein. As used herein, a “therapeutically effective amount” of a composition refers to composition levels in which the physiological effects of a disease or condition are ameliorated or eliminated. A therapeutically effective amount can be given in one or more administrations.

As used herein, the term “overall survival” or “OS” means the observed length of life from the start of treatment to death or the date of last contact.

As used herein, “progression free survival” or “PFS” is the time from treatment to the date of the first confirmed disease progression per RECIST 1.1 and immune-related RECIST (irRECIST) criteria.

“RECIST” shall mean an acronym that stands for “Response Evaluation Criteria in Solid Tumors” and is a set of published rules that define when cancer patients improve (“respond”), stay the same (“stable”) or worsen (“progression”) during treatments. Response as defined by RECIST criteria have been published, for example, at Journal of the National Cancer Institute, Vol. 92, No. 3, Feb. 2, 2000 and RECIST criteria can include other similar published definitions and rule sets. One skilled in the art would understand definitions that go with RECIST criteria, as used herein, such as “Partial Response (PR),” “Complete Response (CR),” “Stable Disease (SD)” and “Progressive Disease (PD).”

The irRECIST overall tumor assessment is based on total measurable tumor burden (TMTB) of measured target and new lesions, non-target lesion assessment and new non-measurable lesions. At baseline, the sum of the longest diameters (SumD) of all target lesions (up to 2 lesions per organ, up to total 5 lesions) is measured. At each subsequent tumor assessment (TA), the SumD of the target lesions and of new, measurable lesions (up to 2 new lesions per organ, total 5 new lesions) are added together to provide the TMTB.

Overall Assessments by irRECIST

Complete Response (irCR)
Complete disappearance of all measurable and non-

measurable lesions. Lymph nodes must decrease to <10

mm in short axis.

Partial Response (irPR)
Decrease of ≥30% in TMTB relative to baseline, non-target

lesions are irNN, and no unequivocal progression of new

nonmeasurable lesions

If new measurable lesions appear in subjects with no

target lesions at baseline, irPD will be assessed. That irPD

time point will be considered a new baseline, and all

subsequent time points will be compared to it for response

assessment. irPR is possible if the TMTB of new

measurable lesions decreases by ≥30% compared to the

first irPD documentation

irRECIST can be used in the adjuvant setting, in

subjects with no visible disease on CT/MRI scans. The

appearance of new measurable lesion(s) automatically leads

to an increase in TMTB by 100% and leads to irPD. These

subjects can achieve a response if the TMTB decreases at

follow-up, as a sign of delayed response.

Based on the above, sponsors may consider

enrolling subjects with no measurable disease and/or no

visible disease in studies with response related endpoints.

Stable Disease (irSD)
Failure to meet criteria for irCR or irPR in the absence of

irPD

Progressive Disease (irPD)
Minimum 20% increase and minimum 5 mm absolute

increase in TMTB compared to nadir, or irPD for non-target

or new non-measurable lesions. Confirmation of

progression is recommended minimum 4 weeks after the

first irPD assessment. An irPD confirmation scan may be

recommended for subjects with a minimal TMTB %-

increase over 20% and especially during the flare time-

window of the first 12 weeks of treatment, depending on the

compound efficacy expectations, to account for expected

delayed response.

In irRECIST a substantial and unequivocal increase

of non-target lesions is indicative of progression.

IrPD may be assigned for a subject with multiple

new non-measurable lesions if they are considered to be a

sign of unequivocal massive worsening

Other
irNE: used in exceptional cases where insufficient data

exist.

irND: in adjuvant setting when no disease is detected

irNN:, no target disease was identified at baseline, and at

follow-up the subject fails to meet criteria for irCR or irPD

As used herein, the terms “subject”, “patient”, or “individual” can be an individual organism, a vertebrate, a mammal, or a human. In some embodiments, the subject, patient or individual is a human.

As used herein, “survival” refers to the subject remaining alive, and includes overall survival as well as progression free survival.

Systems, Devices, and Methods for Classifying Breast Cancer Tumor Samples

Aspects of the operating environment as well as associated system components (e.g., hardware elements) in connection with various embodiments of the methods and systems described herein will now be discussed. Referring to FIG. 1A, an embodiment of a network environment is depicted. In brief overview, the illustrated exploring network environment includes one or more clients 102a-102n (also generally referred to as local machine(s) 102, client(s) 102, client node(s) 102, client machine(s) 102, client computer(s) 102, client device(s) 102, endpoint(s) 102, or endpoint node(s) 102) in communication with one or more servers 106a-106n (also generally referred to as server(s) 106, node 106, or remote machine(s) 106) via one or more networks 104. In some embodiments, a client 102 has the capacity to function as both a client node seeking access to resources provided by a server and as a server providing access to hosted resources for other clients 102a-102n.

Although FIG. 1A shows a network 104 between the clients 102 and the servers 106, the clients 102 and the servers 106 may be on the same network 104. In some embodiments, there are multiple networks 104 between the clients 102 and the servers 106. In one of these embodiments, a network 104′ (not shown) may be a private network and a network 104 may be a public network. In another of these embodiments, a network 104 may be a private network and a network 104′ a public network. In still another of these embodiments, networks 104 and 104′ may both be private networks.

The network 104 may be connected via wired or wireless links. Wired links may include Digital Subscriber Line (DSL), coaxial cable lines, or optical fiber lines. The wireless links may include BLUETOOTH, Wi-Fi, NFC, RFID Worldwide Interoperability for Microwave Access (WiMAX), an infrared channel or satellite band. The wireless links may also include any cellular network standards used to communicate among mobile devices, including standards that qualify as 1G, 2G, 3G, or 4G. The network standards may qualify as one or more generation of mobile telecommunication standards by fulfilling a specification or standards such as the specifications maintained by International Telecommunication Union. The 3G standards, for example, may correspond to the International Mobile Telecommunications-2000 (IMT-2000) specification, and the 4G standards may correspond to the International Mobile Telecommunications Advanced (IMT-Advanced) specification. Examples of cellular network standards include AMPS, GSM, GPRS, UMTS, LTE, LTE Advanced, Mobile WiMAX, and WiMAX-Advanced. Cellular network standards may use various channel access methods e.g. FDMA, TDMA, CDMA, or SDMA. In some embodiments, different types of data may be transmitted via different links and standards. In other embodiments, the same types of data may be transmitted via different links and standards.

The network 104 may be any type and/or form of network. The geographical scope of the network 104 may vary widely and the network 104 can be a body area network (BAN), a personal area network (PAN), a local-area network (LAN), e.g. Intranet, a metropolitan area network (MAN), a wide area network (WAN), or the Internet. The topology of the network 104 may be of any form and may include, e.g., any of the following: point-to-point, bus, star, ring, mesh, or tree. The network 104 may be an overlay network, which is virtual and sits on top of one or more layers of other networks 104′. The network 104 may be of any such network topology as known to those ordinarily skilled in the art capable of supporting the operations described herein. The network 104 may utilize different techniques and layers or stacks of protocols, including, e.g., the Ethernet protocol, the internet protocol suite (TCP/IP), the ATM (Asynchronous Transfer Mode) technique, the SONET (Synchronous Optical Networking) protocol, or the SDH (Synchronous Digital Hierarchy) protocol. The TCP/IP internet protocol suite may include application layer, transport layer, internet layer (including, e.g., IPv6), or the link layer. The network 104 may be a type of a broadcast network, a telecommunications network, a data communication network, or a computer network.

In some embodiments, the system may include multiple, logically-grouped servers 106. In one of these embodiments, the logical group of servers may be referred to as a server farm or a machine farm. In another of these embodiments, the servers 106 may be geographically dispersed. In other embodiments, a machine farm 38 may be administered as a single entity. In still other embodiments, the machine farm 38 includes a plurality of machine farms 38. The servers 106 within each machine farm 38 can be heterogeneous—one or more of the servers 106 or machines 106 can operate according to one type of operating system platform (e.g., WINDOWS NT, manufactured by Microsoft Corp. of Redmond, Wash.), while one or more of the other servers 106 can operate on according to another type of operating system platform (e.g., Unix, Linux, or Mac OS X).

In one embodiment, servers 106 in the machine farm 38 may be stored in high-density rack systems, along with associated storage systems, and located in an enterprise data center. In this embodiment, consolidating the servers 106 in this way may improve system manageability, data security, the physical security of the system, and system performance by locating servers 106 and high performance storage systems on localized high performance networks. Centralizing the servers 106 and storage systems and coupling them with advanced system management tools allows more efficient use of server resources.

The servers 106 of each machine farm 38 do not need to be physically proximate to another server 106 in the same machine farm. Thus, the group of servers 106 logically grouped as a machine farm may be interconnected using a wide-area network (WAN) connection or a metropolitan-area network (MAN) connection. For example, a machine farm 38 may include servers 106 physically located in different continents or different regions of a continent, country, state, city, campus, or room. Data transmission speeds between servers 106 in the machine farm 38 can be increased if the servers 106 are connected using a local-area network (LAN) connection or some form of direct connection. Additionally, a heterogeneous machine farm 38 may include one or more servers 106 operating according to a type of operating system, while one or more other servers 106 execute one or more types of hypervisors rather than operating systems. In these embodiments, hypervisors may be used to emulate virtual hardware, partition physical hardware, virtualized physical hardware, and execute virtual machines that provide access to computing environments, allowing multiple operating systems to run concurrently on a host computer. Native hypervisors may run directly on the host computer. Hypervisors may include VMware ESX/ESXi, manufactured by VMWare, Inc., of Palo Alto, Calif.; the Xen hypervisor, an open source product whose development is overseen by Citrix Systems, Inc.; the HYPER-V hypervisors provided by Microsoft or others. Hosted hypervisors may run within an operating system on a second software level. Examples of hosted hypervisors may include VMware Workstation and VIRTUALBOX.

Management of the machine farm 38 may be de-centralized. For example, one or more servers 106 may comprise components, subsystems and modules to support one or more management services for the machine farm 38. In one of these embodiments, one or more servers 106 provide functionality for management of dynamic data, including techniques for handling failover, data replication, and increasing the robustness of the machine farm 38. Each server 106 may communicate with a persistent store and, in some embodiments, with a dynamic store.

Server 106 may be a file server, application server, web server, proxy server, appliance, network appliance, gateway, gateway server, virtualization server, deployment server, SSL VPN server, or firewall. In one embodiment, the server 106 may be referred to as a remote machine or a node. In another embodiment, a plurality of nodes may be in the path between any two communicating servers.

Referring to FIG. 1B, a cloud computing environment is depicted. A cloud computing environment may provide client 102 with one or more resources provided by a network environment. The cloud computing environment may include one or more clients 102a-102n, in communication with the cloud 108 over one or more networks 104. Clients 102 may include, e.g., thick clients, thin clients, and zero clients. A thick client may provide at least some functionality even when disconnected from the cloud 108 or servers 106. A thin client or a zero client may depend on the connection to the cloud 108 or server 106 to provide functionality. A zero client may depend on the cloud 108 or other networks 104 or servers 106 to retrieve operating system data for the client device. The cloud 108 may include back end platforms, e.g., servers 106, storage, server farms or data centers.

The cloud 108 may be public, private, or hybrid. Public clouds may include public servers 106 that are maintained by third parties to the clients 102 or the owners of the clients. The servers 106 may be located off-site in remote geographical locations as disclosed above or otherwise. Public clouds may be connected to the servers 106 over a public network. Private clouds may include private servers 106 that are physically maintained by clients 102 or owners of clients. Private clouds may be connected to the servers 106 over a private network 104. Hybrid clouds 108 may include both the private and public networks 104 and servers 106.

The cloud 108 may also include a cloud based delivery, e.g. Software as a Service (SaaS) 110, Platform as a Service (PaaS) 112, and Infrastructure as a Service (IaaS) 114. IaaS may refer to a user renting the use of infrastructure resources that are needed during a specified time period. IaaS providers may offer storage, networking, servers or virtualization resources from large pools, allowing the users to quickly scale up by accessing more resources as needed. PaaS providers may offer functionality provided by IaaS, including, e.g., storage, networking, servers or virtualization, as well as additional resources such as, e.g., the operating system, middleware, or runtime resources. Examples of PaaS include WINDOWS AZURE provided by Microsoft Corporation of Redmond, Wash., Google App Engine provided by Google Inc., and HEROKU provided by Heroku, Inc. of San Francisco, Calif. SaaS providers may offer the resources that PaaS provides, including storage, networking, servers, virtualization, operating system, middleware, or runtime resources. In some embodiments, SaaS providers may offer additional resources including, e.g., data and application resources.

Clients 102 may access IaaS resources with one or more IaaS standards, including, e.g., Amazon Elastic Compute Cloud (EC2), Open Cloud Computing Interface (OCCI), Cloud Infrastructure Management Interface (CIMI), or OpenStack standards. Some IaaS standards may allow clients access to resources over HTTP, and may use Representational State Transfer (REST) protocol or Simple Object Access Protocol (SOAP). Clients 102 may access PaaS resources with different PaaS interfaces. Some PaaS interfaces use HTTP packages, standard Java APIs, JavaMail API, Java Data Objects (JDO), Java Persistence API (JPA), Python APIs, web integration APIs for different programming languages including, e.g., Rack for Ruby, WSGI for Python, or PSGI for Perl, or other APIs that may be built on REST, HTTP, XML, or other protocols. Clients 102 may access SaaS resources through the use of web-based user interfaces, provided by a web browser. Clients 102 may also access SaaS resources through smartphone or tablet applications, including. Clients 102 may also access SaaS resources through the client operating system.

In some embodiments, access to IaaS, PaaS, or SaaS resources may be authenticated. For example, a server or authentication server may authenticate a user via security certificates, HTTPS, or API keys. API keys may include various encryption standards such as, e.g., Advanced Encryption Standard (AES). Data resources may be sent over Transport Layer Security (TLS) or Secure Sockets Layer (SSL).

The client 102 and server 106 may be deployed as and/or executed on any type and form of computing device, e.g. a computer, network device or appliance capable of communicating on any type and form of network and performing the operations described herein. FIGS. 1C and 1D depict block diagrams of a computing device 100 useful for practicing an embodiment of the client 102 or a server 106. As shown in FIGS. 1C and 1D, each computing device 100 includes a central processing unit 121, and a main memory unit 122. As shown in FIG. 1C, a computing device 100 may include a storage device 128, an installation device 116, a network interface 118, an I/O controller 123, display devices 124a-124n, a keyboard 126 and a pointing device 127, e.g. a mouse. The storage device 128 may include, without limitation, an operating system, and/or software 120. As shown in FIG. 1D, each computing device 100 may also include additional optional elements, e.g. a memory port 103, a bridge 170, one or more input/output devices 130a-130n (generally referred to using reference numeral 130), and a cache memory 140 in communication with the central processing unit 121.

The central processing unit 121 is any logic circuitry that responds to and processes instructions fetched from the main memory unit 122. In many embodiments, the central processing unit 121 is provided by a microprocessor unit. The computing device 100 may be based on any of these processors, or any other processor capable of operating as described herein. The central processing unit 121 may utilize instruction level parallelism, thread level parallelism, different levels of cache, and multi-core processors. A multi-core processor may include two or more processing units on a single computing component.

Examples of cancer therapy include surgery, chemotherapy, immunotherapy and radiation therapy.

Examples

The present technology is further illustrated by the following Examples, which should not be construed as limiting in any way.

Example 1: Experimental Methods

Methods: We analyzed standard H&E slides for twelve cases of primary triple-negative breast cancer (TNBC) resected from patients prior to the initiation of any therapy. The term triple-negative refers to the absence of estrogen and progesterone receptors and the absence of HER2, a histologic condition associated generally with poor prognosis although paradoxically many patients are cured by modern treatment. All twelve patients were treated by standard of care primary surgery, radiation therapy, and post-operative systemic chemotherapy. Three of the twelve cases experienced eventually developed recurrent disease (ipsilateral breast, bone, brain) while nine of the twelve cases remained disease-free at prolonged follow-up durations. Hence, the initial test set has a representation of cases with both poor and good prognoses.

To count TILs we used QuPATH, an open-source software package for digital pathology image analysis.⁷We trained a random forest classifier to detect and quantify TILs as compared with cancer cells. For each case, we examined a square area representative of the tumor, including stroma, toward the center of the mass. The side length of this larger square was 1000 μm, which we divided into sixteen equal smaller squares of 250 μm by 250 μm each, counting N, the number of TILs in each small square. Letting

$S (x) = \sum_{t = 1}^{x} N (i)$

our metric is

$D = 1 + \frac{2 [\ln S (16) - \ln N_{\max}]}{\ln (16)}$

with N_maxbeing the number of TILs in small square with the highest number of TILs. Intuitively, a D=2 would be consistent with the fractal dimension of a simple sheet, while a D=3 would be consistent with the fractal dimension of a solid mass of TILs.

Example 2: The Methods of the Present Technology Accurately Classify Breast Cancer Tumor Samples

The mean D for the three cases who recurred was 2.77 with a standard deviation of 0.0444. The Mean/for the 9 cases who remained free of disease was 2.65 with a standard deviation of 0825. This is a statistically significant difference at p<0.03 using the Student's t-test, two-sided, for populations of unequal variance. Of the cases with the top four values of D, ranging from 2.72 to 2.84, three suffered recurrent disease while of the eight cases with values of D<2.72, ranging from 2.55 to 2.70, none have recurred.

These results show that the dimensionality of TIL anatomic distribution predicts prognosis in breast cancer (e.g., triple negative breast cancer) patients. While we used digital pathology methods to count TILs, the calculation of our metric is agnostic to the method of TIL counting.

In addition to the clinical utility of TIL dimensionality, its etiology is a topic of interest. In a clinically-relevant animal model it was shown that cancer cells starting from a given site can traverse a hematogenous route to seed discrete, unconnected tumors.⁸This phenomenon of cell mobility between sites of disease has also been confirmed in cancer xenografts by single-cell sequencing.⁹An anatomic concurrence of TILs with such cancer cell seeds has been corroborated, albeit not quantified, as suggested in FIG. 6E of Bankhead, P. et al. Scientific Reports (2017).

Hence the quantitative anatomic arrangement of the TILs as estimated by the calculation of D may be a measure of the magnitude of self-seeding, which could have broad pragmatic implications.¹⁰Furthermore, TILs have been shown to exert many non-immunological biological effects on cancer cells, including promoting resistance to chemotherapy.¹¹

As to Immunobiology and its prognostic and therapeutic consequences, the methods of the present technology can be applied to the study of a large clinically annotated dataset that includes immunohistochemically defined leukocyte subsets. Furthermore, these analytic methods can be applied to other countable, clinically relevant features of breast cancer including cancer cells with markers for hormone receptors, HER2, and Trop2.
