The biliary system is comprised of a series of ducts, organs, and structures that produce, store, and transport bile from the liver to the small intestine. Bile is produced in the liver and stored in the gallbladder until eating, when it is released into the duodenum through the bile ducts. The bile aids in breaking down fats to allow for nutrient absorption. The document provides diagrams of MRI images depicting the anatomy of the biliary system.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

2. The Anatomy of the Biliary System
The biliary system (also called the biliary tract or
biliary tree) is a system of ducts (narrow tubular
structures), organs (including the liver,
gallbladder and pancreas), and associated
structures that function to produce, store,
secrete and transport bile.
MAAJIDMALIKOFFICIAL@GMAIL.COM
3. BILE
Bile is a greenish brown, thick substance, produced in the
liver and stored in the gallbladder. Bile’s function is to be
released into the small intestine when a fatty meal is
ingested, to help breakdown fats for absorption.
Once food has gone through the initial process of digestion
in the stomach, it moves into the duodenum (the first
segment of the small intestine). Bile and other digestive
secretions travel into the duodenum via the biliary tract
(through the system of bile ducts). These continue the
digestive process by breaking down food so its nutrients can
be absorbed.
MAAJIDMALIKOFFICIAL@GMAIL.COM
4. DUODENUM
The first of three sections of the small intestine, which
receives food from the stomach and digestive juices
from the liver, gallbladder, and pancreas via the biliary
tract. This is the part of the small intestine that is
primarily involved in breaking down food so that
nutrients can later be absorbed in the jejunum (middle
section of the small intestine).
MAAJIDMALIKOFFICIAL@GMAIL.COM
5. LIVER
A large glandular organ that performs many vital
metabolic functions, such as the digestion of fats
to make energy in the body. The liver cells
function to make bile.
MAAJIDMALIKOFFICIAL@GMAIL.COM
6. BILE DUCT
This is a small hollow tube that functions to
transport bile. The biliary system is comprised of
a system of these ducts that flow from the liver to
the gallbladder for storage and finally into the
small intestine (duodenum).
MAAJIDMALIKOFFICIAL@GMAIL.COM
7. GALLBLADDER
A pear-shaped organ located in front of the
duodenum, just underneath the live, it
functions to store bile. It connects to the
cystic duct.
MAAJIDMALIKOFFICIAL@GMAIL.COM
8. PANCREAS
A large gland, located behind the stomach, it
secretes pancreatic juice (containing pancreatic
enzymes, such as lipase to break down fats) into
the biliary system via the pancreatic duct.
MAAJIDMALIKOFFICIAL@GMAIL.COM
11. STRUCTURE
The biliary system is comprised of a series of ducts, organs,
and other structures responsible for producing, storing, and
transporting bile. The bile is made in the cells of the liver and
travels to the gallbladder to be stored for later use.
When a fatty meal is ingested, the bile is released and it
travels to the small intestine (through this system of ducts)
to its final destination, the duodenum.
MAAJIDMALIKOFFICIAL@GMAIL.COM
12. BILE FLOW THROUGHTHE BILIARY SYSTEM
Through the system of ducts and other structures of the biliary
system, bile travels in a controlled manner, the bile flows:
From the liver, where bile is made in the liver cells, next it flows into a
system of ducts located inside and outside of the liver, these ducts
function to collect the bile, once collected, the bile travels to the right
and left hepatic ducts.
From the right and left hepatic ducts, bile then flows into the common
hepatic duct.
MAAJIDMALIKOFFICIAL@GMAIL.COM
13. CONTINUE
The common hepatic duct joins the cystic duct and the bile
flows from the common hepatic duct into the cystic duct.
The cystic duct is connected to the gallbladder. Bile flows from
the cystic duct into the common bile duct.
The common bile duct (CBD) is located where the common
hepatic duct and the cystic duct join. The CBD runs from the
liver to the duodenum where bile is excreted through a
muscular opening called the sphincter of Oddi.
MAAJIDMALIKOFFICIAL@GMAIL.COM
14. FUNCTION OF THE BILIARY SYSTEM
There are three important functions of the biliary system, these
include:
Draining the waste products from the liver (into the
duodenum)
Secreting bile in a controlled release manner
Transporting bile and pancreatic juices (to be used to help
breakdown food in the small intestine
