This document discusses the principles and procedures of colposcopy examinations. It begins by defining a colposcope and its main uses. The most common reason for referral is abnormal cervical screening tests indicating possible precancerous lesions. During the exam, the cervix is examined under magnification with saline, acetic acid, and Lugol's iodine to identify any abnormal white lesions that could indicate precancer or cancer. The document outlines the proper colposcopy instrumentation, examination steps including the principles behind using acetic acid and Lugol's iodine, how to interpret the results, and the importance of thoroughly documenting findings.

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. • A colposcope is a low-power,stereoscopic,
binocular field microscope with a powerful
light source used for magnified visual
examination of the uterine cervix to help in
the diagnosis of cervical neoplasia.
3. • The most common indication of referral for
colposcopy is positive screening tests .
4. • Cytologically reported (CIN 2 and CIN 3)
may be associated with an underlying
invasive squamous cell cervical cancer or
adenocarcinoma.
5. • It is important that all women with high-
grade abnormalities be referred
immediately for diagnostic colposcopy.
• Variation in the management of women
(CIN 1).
7. • Indications for colposcopy
• Suspicious-looking cervix
• Invasive carcinoma on cytology
• CIN 2 or CIN 3 on cytology
• Persisting (for more than 12-18 months) low-grade
(CIN1) abnormalities on cytology
• CIN 1 on cytology
• Persistently unsatisfactory quality on cytology
• Infection with oncogenic human papillomaviruses (HPV)
• Acetopositivity on visual inspection with acetic acid .
• Acetopositivity on visual inspection with acetic acid using
magnification .
• Positive on visual inspection with Lugol s iodine .
8. • 20% with CIN 1 on cytology may harbour higher-
grade lesions It is advisable that women with any
grade of CIN on cytology be referred for
colposcopy in developing countries.
(Shafi et al., 1997).
9. • If the clinician observes characteristics of a cervix that
looks suspicious, no matter what the cytology
shows, it is advisable to refer the woman for
colposcopic examination.
• Likewise, observation of an area of leukoplakia
(hyperkeratosis) on the cervix should prompt a
colposcopic examination.
(Howard etal.,2001)
10. • The potential roles of 3-5% acetic acid
application and subsequent visual
inspection of the cervix with magnification
(VIAM) or without (VIA) and of visual
inspection with Lugol s iodine (VILI) are
still under study as screening techniques .
(University of Zimbabwe, JHPIEGO study, 1998; Denny et al., 2000;
Belinson et al., 2001; Sankaranarayanan et al., 2001).
12. • The head of the colposcope, called the optics carrier ,
contains the objective lens .
• Light source, green and/or blue filters to be interposed
between the light source and the objective lens,
• A knob to introduce the filter.
13. • Modern colposcopes usually permit adjustable
magnification, commonly 6x to 40x.
14. • Focusing the colposcope is accomplished by
adjusting the distance between the objective
lens and the woman by positioning the
instrument at the right working distance.
15. • The working distance (focal length) between the
objective lens and the patient is quite important .
16.
17.
18. Colposcopic instruments
• The instruments needed for colposcopy
are few and should be placed on an
instrument trolley or tray beside the
examination table:
• bivalve specula .
• vaginal side-wall retractor .
• cotton swabs, sponge-holding forceps,
long (at least 20cm long)
22. Principles of colposcopy examination
procedures
• Saline technique:The key ingredients of
colposcopic practice are the examination
of the features of the cervical epithelium
after application of saline, 3-5% dilute
acetic acid and Lugol s iodine solution in
successive steps.
23. Principles of acetic acid test
• The other key ingredient in colposcopic practice, 3-5%
acetic acid, is usually applied with a cotton applicator or
with a small sprayer. It helps in coagulating and clearing
the mucus.
24.
25. • With low-grade CIN, the acetic acid must penetrate into
the lower one-third of the epithelium (where most of the
abnormal cells with high nuclear density are located).
26. • The acetowhite appearance is not unique
to CIN and early cancer. It is also seen in
other situations when increased nuclear
protein is present:
27. • immature squamous metaplasia,
• congenital transformation zone.
• healing and regenerating epithelium (associated with inflammation),
• leukoplakia (hyperkeratosis) and condyloma.
• While the acetowhite epithelium associated with CIN and preclinical
early invasive cancer is more
• dense,
• thick and
• opaque with well demarcated margins from the surrounding
normal epithelium.
28. • Acetowhitening due to inflammation and
healing is usually distributed widely in the
cervix, not restricted to the transformation
zone.
• The acetowhite changes associated with
immature metaplasia and inflammatory
changes quickly disappear, usually within
30-60 seconds.
29. • Acetowhitening associated with CIN and invasive cancer
• quickly appears .
• persists for more than one minute.
• The acetic acid effect reverses much more slowly in
high-grade CIN lesions and in early pre-clinical invasive
cancer than in low-grade lesions, immature metaplasia
and sub-clinical HPV changes.
30. • The main goal of colposcopy is to detect the
presence of high-grade CIN and invasive
cancer.
• The entire epithelium at risk should be well
visualized, abnormalities should be identified
accurately and assessed for their degree of
abnormality, and appropriate biopsies must be
taken.
31. • Principles of Schiller s (Lugol s) iodine test The principle
behind the iodine.
• If there is shedding (or erosion) of superficial and
intermediate cell layers associated with inflammatory
conditions of the squamous epithelium, these areas do
not stain with iodine and remain distinctly colourless in a
surrounding black or brown background.
32. • The routine use of iodine application in
colposcopic practice is recommened as
this may help in identifying lesions
overlooked during examination with saline
and acetic acid.
33. Documentation of colposcopic findings
• The record of colposcopic findings for each visit
should be documented carefully by the
colposcopists themselves, immediately after the
examination.
34. • Various experts have recommended standardized
representations of colposcopic findings in a drawing.
• Since an examination of the entire lower genital tract
should be performed whenever a woman is referred for
colposcopy, the colposcopist must be able to record the
clinical findings in the vaginal, vulvar, perianal and anal
epithelium.
