The prostate is the gland below a man's bladder
that produces fluid for semen. Prostate cancer is common among older men. It is
rare in men younger than 40. Risk factors for developing prostate cancer
include being over 65 years of age, family history, being African-American, and
some genetic changes.
Symptoms of prostate cancer may include:
-- Problems passing urine, such as pain,
difficulty starting or stopping the stream, or dribbling
-- Low back pain
-- Pain with ejaculation
Your doctor will diagnose prostate cancer
by feeling the prostate through the wall of the rectum or doing a blood test
for prostate-specific antigen (PSA). Other tests include ultrasound, x-rays, or
a biopsy.
Treatment often depends on the stage of the
cancer. How fast the cancer grows and how different it is from surrounding
tissue helps determine the stage. Men with prostate cancer have many treatment
options. The treatment that's best for one man may not be best for another. The
options include watchful waiting, surgery, radiation therapy, hormone therapy,
and chemotherapy. You may have a combination of treatments.
Prostate cancer or tumor is the most common cancer in men other than non-melanoma skin cancer.
The majority (more than 75%) of cases occur in men over age 65.
Prostate cancer is a malignant tumor of the prostate gland.
A basic approach towards carcinoma of prostate , symptoms, investigations , diagnosis, staging, treatment and follow up along with recent advances in surgeries, vaccines and immunotherapy.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

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

CDSCO and Phamacovigilance {Regulatory body in India}NEHA GUPTA
The Central Drugs Standard Control Organization (CDSCO) is India's national regulatory body for pharmaceuticals and medical devices. Operating under the Directorate General of Health Services, Ministry of Health & Family Welfare, Government of India, the CDSCO is responsible for approving new drugs, conducting clinical trials, setting standards for drugs, controlling the quality of imported drugs, and coordinating the activities of State Drug Control Organizations by providing expert advice.
Pharmacovigilance, on the other hand, is the science and activities related to the detection, assessment, understanding, and prevention of adverse effects or any other drug-related problems. The primary aim of pharmacovigilance is to ensure the safety and efficacy of medicines, thereby protecting public health.
In India, pharmacovigilance activities are monitored by the Pharmacovigilance Programme of India (PvPI), which works closely with CDSCO to collect, analyze, and act upon data regarding adverse drug reactions (ADRs). Together, they play a critical role in ensuring that the benefits of drugs outweigh their risks, maintaining high standards of patient safety, and promoting the rational use of medicines.
2. CONTENTS OF PRESENTATION:
• WHAT IS PROSTATE ?
• Structure of prostate.
• PATHOPHYSIOLOGY OF PC.
• RISK FACTORS FOR PC.
• CLINICAL PRESENTATION.
• DAIGNOSIS .
• TREATMENT.
3. WHAT IS PROSTATE ?
• It is small gland located just below the UB . Its weight is
about 40gm. The growth of prostate is under the control of
testosterone.
• Its size is about the size of walnut that surrounds the first
part of the male urethra at the base of the bladder . It is
present only in male. Prostate secretes prostatic fluid, which
is emptied into prostatic urethra through prostatic sinuses .
4.
5. Structure of prostate:
• The whole prostate is surrounded by capsule of connective tissues
and smooth muscle.
Prostate is divided into three zones.
1. Peripheral zone
2. Central zone
3. Transitional zone
6. • Peripheral zone is the largest zone and is outer most layer. Most of
cancer arise in this part . Adenocarcinoma is the most common
carcinoma. This carcinoma is because of genetic mutation in luminal
and basal cells.
7.
8. PATHOPHYSIOLOGY:
• Prostate functions and growth are controlled by androgens i-e
testosterone, dihydrotestosterone. In the prostate, free testosterone
diffuses into the epithelial cells where it is converted to DHT by alpha
reductase enzymes. This DHT then complexes with their receptor
(androgen receptor) and bind to DNA and result in stimulation of
prostate growth. This growth continues from puberty to age 30 to 35,
and onward no more growth of prostate occurs, after 45 to 60 age
only hypertrophy occurs. Sometimes this control growth is invaded
by genetic mutation and result in uncontrolled growth of cells. This
Genetic mutation mostly occurs in luminal cell and basal cell of tiny
glands in prostate. And this glandular carcinoma of prostate is called
adenocarcinoma.
9. PC RISK FACTORS:
• AGE: PC occurs mainly in older age, about six cases in ten are diagnosed in
men aged 65 or older, and it is rare before age 40.
The average age at thee time of diagnosis is about 66.
• ETHNICITY: Higher in African American men, lower in Asian men.
• FAMILY HISTOR: Having a father or brother with PC more than a doubles a
risk of developing this disease.
• DIET: High in red meat, low in vegetable.
• GENES: Genes which are common for mutation are
1. BRCA 1
2. BRCA 2
3. HOXB13
4. MSH2
10. CLINICAL PRESENTATION:
• Clinical symptoms of PC are similar to those for BPH, and there are no
symptoms which correlate specifically to early PC.
• Localized Disease
Asymptomatic
• Locally Invasive Disease
Ureteral dysfunction,
frequency,
hesitancy, and dribbling Impotence
11. • Advanced Disease
Back pain
Cord compression
Lower extremity edema
Pathologic fractures
Anemia
Weight loss
12. DIAGNOSES:
• Diagnostic tests and Staging Workup for Prostate Cancer :
Initial tests :
1. Digital rectal examination (DRE): A DRE is an important diagnostic
tool for PC with an estimated sensitivity of more than 60%.
2. Prostate-specific antigen (PSA) : Measurement of PSA is an accurate
and clinically useful biochemical marker because it is specific to
prostate tissue and produced by the columnar epithelial cells in the
prostate gland.
13. 1. Trasnsrectal ultrasonography (TRUS) if either DRE is positive or PSA is
elevated Biopsy: TRUS of the prostate is commonly used to aid the
diagnosis of PC. Sensitivity ranges from 48% to 100%.
2. Prostate biopsy : This is a definitive method to detect PC. TRUS guided
biopsy will help obtain samples from the peripheral and transitional
zones of the prostate and other suspicious areas.
Staging tests
1. Gleason score on biopsy specimen: The most widely accepted histological grading
system, which corresponds to biological malignancy, is based on the Gleason scale
. A score of 1 corresponds to well-differentiated cells, while a score of 5
corresponds to poorly differentiated cells. The higher the score, the more
aggressive the cancer.
16. TREATMENT:
• Treatment plans are applied according to condition of disease. Disease
condition may be,
1. Localized PC
2. Locally advanced PC
3. Metastatic PC
• Localized PC:
1. Active surveillance: In this patient is generally observed for
symptoms and treatment is not given.
2. Radical prostatectomy
3. Radical external beam radiotherapy
4. Cryosurgical ablation of prostate : Cryosurgical ablation of
prostate (CSAP). Cryosurgical ablation involves freezing the
prostate which results in cell death by protein denaturation,
direct rupture of cellular membranes and apoptosis.
17. 5.Interstitial brachytherapy: With interstitial brachytherapy radioactive
isotope seeds are placed in the prostate. These implants can emit
radiation of low energy over several weeks and can be temporary or
permanent. This treatment has the potential advantage of less erectile
dysfunction than other treatment.
18.
19. • Locally advanced PC:
when surrounding areas with prostate are involve, they are considered locally
advanced. Different treatment plans are used to treat locally advanced PC.
1. Hormonal therapy OR androgen deprivation therapy:
Androgens are produced by testes(95%)
under stimulation of luteinizing hormone(LH) and LHRH from pituitary gland and 5% by adrenal
gland. Deprivation of androgens can be achieved by two methods. (1) surgical castration (2) medical
castration. Medical castration can be achieved by medicines.
1. LHRH AGONISTS : It includes the
gosereline, leuprorelin, triptorelin, histrelin.
2. Antiandrogens :
cyproterone acetate, megasterol acetate, nilutamide, flutamide, bicalutamide.
