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
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
Anti ulcer drugs and their Advance pharmacology ||
Anti-ulcer drugs are medications used to prevent and treat ulcers in the stomach and upper part of the small intestine (duodenal ulcers). These ulcers are often caused by an imbalance between stomach acid and the mucosal lining, which protects the stomach lining.
||Scope: Overview of various classes of anti-ulcer drugs, their mechanisms of action, indications, side effects, and clinical considerations.

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

2. Definition- decrease in the number of absolute neutrophil
count (ANC) in peripheral blood.
Absolute neutrophil count(ANC)= mature granulocytes +
neutrophil band cells.
Neutrophil count must be stratified for age and race.
• At birth predominant but rapidly decrease in first few
days of life.
• Infancy 20-30% of TLC
• At 5 yrs equal number of neutrophils and lymphocytes
count
• In adults characteristic 70% predominance of neutrophils
is usually attended during puberty.
3. For white children lower limit of normal for ANC is
1500/ cu mm while
For black children its 1200/ cu mm.
Mild neutropenia - ANC 1000 - 1500/ cu mm
Moderate neutropenia – ANC 500 – 1000/ cu mm
Severe neutropenia – ANC <500/ cu mm
Agranulocytosis – ANC <200/ cu mm
Profound neutropenia – ANC<100/ cu mm
Prolonged neutropenia – lasting >7 days
4. The relative lower limit of normal in blacks likely
reflects the prevalence of the Duffy negative (Fy-/-)
blood group, which is selectively enriched in
populations in malaria belt of Africa and is associated
with ANCs 200-600/ cu mm less than those who are
Duffy positive.
5. Development of fever in a neutropenic patient.
Defined as single oral/axillary temperature >38.3˚C
(101˚F) or two consecutive temperature >38˚C (100˚F)
in a 12 hr period for at least 1hr with ANC <500/cu mm
or <1000 cu mm with expected decline to <500/cu mm
during the next 48 hrs.
6. Common in children on chemotherapy and the most
common oncologic emergency.
The risk of infection is clearly increased when ANC drop
below 1000/mm3, with a marked increase when the ANC is
below 500/mm3.
Neutropenic patient can have serious life threatening
infections even in the absence of fever and may not present
with any localizing symptoms and signs of infection such as
exudate, fluctuance and regional lymphadenopathy,
sometimes only fever remain the only consistent early sign.
7. Approximately 48 to 60% patients who become febrile
have an established or occult infection.
Common sites of infection are the alimentary tract (i.e.,
mouth, pharynx, esophagus, large and small bowel and
rectum), perirectal abscess, sinuses, throat, ear (otitis
media), lungs and skin( cellulitis, furunculosis).
Catheter and IV sites are potential source of infection.
8. Gram positive bacteria -
Staphylococcus spp. (e.g. S. epidermidis and S. aureus)
Streptococcus spp. (alpha-hemolytic; e.g., S. mitis)
Enterococcus spp. (e.g. E. faecium, E. faecalis)
Clostridium spp. (C. difficile, C. septicum, C. tertium)
Gram-negative bacteria-
Enterobacteriaceae (E. coli, Klebsiella spp., Enterobacter
spp.)
Pseudomonas aeruginosa and
Stenotrophomonasmaltophilia
Anaerobes (e.g. Bacteroides spp. and Prevotella spp.)
9. Fungi-
Candida spp. (e.g. C. albicans, C. glabrata, C.
tropicalis, C. krusei)
Aspergillus spp. (e.g. A. fumigatus, A. flavus, and A.
terreus)
Fusarium spp. (e.g. F. solani and F. oxysporum)
Cryptococcus neoformans
Pneumocystis jiroveci (formerly, P. carinii)
12. History
Fever -onset, duration and severity
Associated localizing symptoms: Ear, nose, throat,
respiratory, gastrointestinal tract, musculoskeletal and
urinary system.
Phase of chemotherapy (intensive vs. non intensive)
Duration since the last chemotherapy
Recent hospitalization and antibiotics received, if any
13. Examination
Vitals- in every patient of suspected febrile
neutropenia, the patient may appear well despite being
in a state of hemodynamic compromise.
Detailed physical examination focusing on possible
sites of infection must be undertaken. Sites that are
commonly overlooked include oral cavity, ear, sinuses,
skin, nails, perianal area, intravascular catheter
insertion site and the site of bone marrow aspiration.
14. Investigations
First line investigations- to be performed in every case
(1).Complete blood count, including differential leukocyte count and
ANC
(2). Serum electrolytes, urea and creatinine
(3). Blood culture: Obtain as early as possible and always before the
administration of antibiotics. Two sets of blood cultures from separate
venipuncture sites should ideally be drawn. In the presence of a
central venous catheter, a blood culture should be obtained from each
lumen of the catheter and another from peripheral vein.
(4). Chest radiograph: mandatory for all, initial x-ray may be non
informative but must be taken as a baseline for comparison with later
films.
(5). Cultures from any other site, as clinically relevant. This includes
stool, urine, cerebrospinal fluid, skin, respiratory secretions or pus.
15. Second line investigations- Dictated by the clinical course:
(1).CT scan of chest/paranasal sinuses may be indicated in
patients with suspected fungal infection.
(2).Bronchoalveolar lavage: If pneumonia is non-resolving/
non-responding.
(3).Skin biopsy, from skin nodules, if any.
Despite advances in diagnostic methods, infection is
documented only in 30-40% patients.
16. Risk stratification is crucial in determining the
appropriate-
Choice of antimicrobials,
Route of administration (intravenous vs. oral),
Setting (inpatient vs. outpatient) and
Duration.
The patients can be classified as low or high risk
17. Low risk High risk
Neutropenia expected to resolve in
about 7 days
Indicators:
• Afebrile for 24hrs
• Clinically well, hemodynamically
stable
• Sterile blood culture
• Control of local infection
• Evidence of bone marrow recovery
with rising polymorphs count/
platelets/ ANC
• Non-intensive phase of
chemotherapy e.g., maintenance
phase of chemotherapy
• Malignancy in remission
• ANC≥100/mm3 and likely to rise
within the next 7 d.
Neutropenia >7days
Indicators
• Fever persisting
• Culture positive
• No evidence of bone marrow
recovery
• Recent intensive chemotherapy
• Profound neutropenia (ANC<100
cells/mm3), anticipated to extend
for >7 d.
• Evidence of hypotension,
respiratory distress or hypoxemia.
• Mucositis interfering with oral
intake or resulting in diarrhea
18. Presence of fever >39˚C, associated hypotension, ANC<100
cu mm, duration of neutropenia >7days frequently
associated with bacteremia.
Santolaya, et al found serum CRP more than 90 mg/L,
hypotension, relapsed leukemia, platelet count less than
50,000/mm3 and recent chemotherapy to be useful predictors
of serious bacterial infection.
Klaassen et al found an absolute monocyte count less than 100
cell/mm3, co-morbidity and abnormal chest radiograph to
correlate with high risk for significant bacterial infection.
For adults- the Multinational Association of Supportive Care
in Cancer (MASCC) score is used for risk stratification.
Patient with score with ≥21 are at lower risk of complications.
19. General considerations-
Pro- active steps must be taken to reduce incidence of
hospital acquired sepsis.
Barrier nursing practise- frequent hand washing, the
use of alcohol based hand rub in between patients and
wearing gloves must be ensured .
Use of IV fluids, central lines, foley’s catheter etc. must
be restricted, if possible.
20. Administration of IV fluids for minor reasons should be
avoided.
Nasogastric feeding should be encouraged in patients with
anorexia or mucositis.
Rectal enemas, suppositories, and rectal examinations are
contraindicated in neutropenic patients
High-risk’ patients are to be hospitalized and administered
broad-spectrum intravenous antibiotics
Empirical treatment should begin as soon as possible, even
before the results of cultures are available.
21. Important considerations during initial empirical
therapy-
• Risk stratification
• Any focal signs and symptoms, site of infection (e.g.,
lung)
• Antimicrobial susceptibilities of local pathogens
• Recent hospitalization, recent antibiotic exposure or
prophylactic drugs
• Past history of infection (especially fungal or resistant
bacterial such as ESBL or MRSA infection)
• Most common potentially infecting organism based on
type of immune defect
• Co-morbid conditions.
22. Care-takers are advised not to administer paracetamol
at home as it may mask fever and can lead to delay in
seeking medical care.
Administer the first dose of antibiotics without any
delay. Delay in initiating antimicrobials significantly
increases the morbidity and mortality.
23. Anti-pseudomonal agents-
penicillin (piperacillin-tazobactum), antipseudomonal
cephalosporin (cefoperazone-sulbactum) or
carbepenems (meropenem or imipenem-cilastatin) or
cefepime is recommended as first line by Infectious
Disease Society of America
BUT
no significant differences in treatment failure, including
antibiotic modification, infection-related mortality, or
adverse events were observed while comparing anti-
pseudomonas penicillin± aminoglycoside regimen with
carbapenem monotherapy in a recent meta analysis.
24. Empirically combination of antipseudomonal
antibiotic (ceftazidime, cefaperazone/ salbactam) + an
aminoglycoside is used as first line choice.
Switch to second line drugs: Vancomycin and
Carbepenems (meropenem or imipenem-cilastatin)
after 48–72 h, if fever is unrelenting and there is no
improvement in the clinical condition.
Colistin- reserved as a third line drug.
If the cultures yield a specific pathogen, the regimen
should be modified accordingly
For low risk FN oral amoxicillin- clavulinate with
ofloxacin OR cetrioxone with amikacin
25. Indications for need of vancomycin in initial regimen if
patient has -
• Hypotension or evidence of septic shock
• Obvious catheter related infection
• H/O colonization with MRSA
• High risk for viridans streptococci (severe mucositis/ AML /
prior use of quinolone prophylaxis).
If indwelling line insitu or no response in 48 hrs
antistaphylococcal antibiotic should be added.
If fever persist for 4-5 days antifungal (eg. Amphotericin
B) should be added.
Discontinuation should always be kept in mind to minimize
development of bacterial resistance
26. Add antistaphylococcal drug and if febrile at 4-5 days add antifungal

P. jiroveci can cause pneumonia regardless of
neutrophil count, prophylaxis with trimethoprim-
sulfamethoxazole against PCP is an effective
preventive strategy and should be provided to all
children undergoing active treatment for malignancy.
29. Hematopoietic growth factor-
G-CSF (Filgrastim) @5mcg/kg/day in addition to
antibiotics is useful in children with complicated febrile
neutropenia (pneumonia, hypotension, invasive fungal
infection or multi organ dysfunction), it results in-
• more rapid neutrophil recovery
• relatively fewer days of antibiotic use
• Shortens length of hospital stay
• Reduces mortality and morbidity
But G-CSF has no role in the management of children
with uncomplicated febrile neutropenia.
