Introduction • Research into health problems in developing countries
has traditionally focused on infectious and nutritional diseases especially in children.
• Lately attention was focal at HIV /TB and AIDS issues alone
• Now there is emergence of XDR, and MDR-TB• An assumption often made is that chronic diseases, especially
cancer are rare diseases which affect only the older segment of our community
• This assumption is wrong• Cancer mortality in adult is 15-84 , and HIV EPIDEMIC LEAD TO
RISE IN VIRUS RELALATED CANCERS SUCH AS CANCER OF THE CERVIX -Hughes-Davies & Spittle 1991
![Page 10: Cancer of the Cervix burden in southern africa and lesotho - sharing experiences](https://reader038.vdocuments.net/reader038/viewer/2022102602/554b685bb4c90551118b491a/html5/thumbnails/10.jpg)
• Cervical cancer is both preventable and curable,• provided it is detected at an early stage. • In developed countries 80% of cervical cancer cases
detected are cured because of early detection. • However, in developing countries 80% of cervical
cancer cases are incurable at the time of detection, if they are detected at all.
• (Bulletin of the World Health Organization, 1996, 74 (4): 345-351)

Global burden on cervical cancer• ½ million women die of cervical cancer world wide/ yr• Cervical cancer is the most common cancer in Lesotho ¹ • with a high pick up age 40-49 ¹ and the leading cause of death from
cancer amongst women in sub Saharan Africa.²• Cervical cancer screening programs have reduced the incidence of
cancer of the cervix• because cervical cancer generally develops slowly and has a readily
detectable and treatable precursor condition [severe dysplasia / Carcinoma insitu (CIS)] – By Cytology
• It can be prevented through screening and treatment of at risk women.
• Through vaccination of young population for high risk HPV viruses which cause CXCA

Cancer definition• Cancer is a neoplastic proliferation
of abnormal cells, invading surrounding tissue and giving distance metastases
• Cancer of the cervix is the neoplastic proliferation of epithelial tissue covering the lining of the neck of the womb in women
• Abnormal proliferation starts with the genetic aberration in a single cell genetic material, which grows and give a clone of abnormal cells
• A number of factors contribute into the cellular disturbance ( see later)

Signs and symptoms/ clinical presentation• Early signs:• Abnormal vaginal bleeding which could be • Intermenstrual• Post coital bleeding• Post menopausal bleeding• Watery offensive vaginal discharge• The cervix is friable , hard with contact bleeding on
examination( the dysplastic cells have poor cohesiveness, so the underlining vascular system in the lamina propriae become exposed.)
• The Cytologist should expect micro-biopsies or an inadequate smear scraping because of blood
• The Clinician should blot the blood with 5%CH3COOH

Clinical Staging of CACX• Precancer: Dysplasia- a degree of epithelial abnormality
occurs when normal cells undergo bad changes but too early to be called malignant, however if the condition is left untreated will progress to cancer. CIN 1, 2, and CIN3
• There is no agreement over the progression rate• Stage CA CX 1.O = CAO= CIN3/CAO= confined to surface
epithelium• CACX stage 1.A= Less or equal < 5mm invasive beyond
stroma= micro-invasive CACX• CACX stage 1.B= > 5mm invasive beyond stroma• Stage CACX 2. A = Spread beyond CX• CACX 2.B =Early para-metrium invasion

cont• Total cost of treatment was crude estimated to M 10, 692 000.00 Million for already histological
confirmed cervical cancer in a period• Cytological Intervention could have been done
earlier in the women ‘s lives (10 yrs) had the right criteria for screening been used-
• All invasive cases SHOULD HAVE been / have been referred to South African hospital for treatment at a standard cost of R108 000 per patient course of treatment until the patient is cancer free. (This fee was R35 000 in 1995, WHO Report)
• What is the Cost Now ??????????

• CYTOLOGY COST REDUCTION INTERVENTION =M 17 064 000, 00 m in the stipulated
period ( 1 year.3months)• This depends upon if all patients
HAVE been well recalled/followed up using SOP’s and treated Modalities in the Guidelines when intervention is still possible

So What do we do? Pap smears and HPV testing has to be capacitated in
Lesotho There is a strong relationship between HPV, HIV and
cervical cancer progression rate Direct Visual Inspection (DVI) with immediate treatment
can reduce cervical cancer by about 37% in a single visit, BUT requires quality control, competency, QMS and is provider dependent .
Over diagnosis possible- (ethico-Legal issues) Immunization against HPV is now feasible and can
reduce cervical cancer by about 70%!

chromogenic in situ hybridization• CISH, or chromogenic in situ hybridization, is a process in which a
labeled complementary DNA or RNA strand is used to localize a specific DNA or RNA sequence in a tissue specimen.
• CISH is used to evaluate gene amplification, gene deletion, chromosome translocation, and chromosome number.
• CISH utilizes conventional peroxidase or alkaline phosphatase reactions visualized under a standard bright-field microscope, and is applicable to formalin-fixed, paraffin-embedded (FFPE) tissues, FNAB , blood or bone marrow smears, metaphase chromosome spreads, and fixed cells. CISH offers:
Evaluation of gene status simultaneously with tissue morphology ■Use of existing bright-field microscopy and techniques similar to FISH ■Archivable and quantitative results■

MOLECULAR ANATOMY OF HPV
• HPV consists of a double-stranded circular DNA genome, containing 7800–7900 base pairs,
• a non-enveloped virion and an icosahedral capsid. • The genome is organized into three regions,• the upstream regulatory region (URR, non-coding)• and the early gene regions (EGR)• late gene regions (protein encodeing). LGR

cont• These encode all the viral proteins except
for the viral capsid proteins, which are encoded in the late region..
• The E6 and E7 proteins are of specific importance in cancer.
• In fact, recent studies have shown that the oncogenic potential of the high-risk HPV genotypes depend on E6 and E7 expression.
![Page 83: Cancer of the Cervix burden in southern africa and lesotho - sharing experiences](https://reader038.vdocuments.net/reader038/viewer/2022102602/554b685bb4c90551118b491a/html5/thumbnails/83.jpg)
HPV AND CELL INTRERACTION• The importance of HPV E6 in cancer appears to be
because of its effects on the epithelial cellular tumor suppressor gene, p53.
• Alterations in the p53 gene, including deletion, insertion and point mutation are the most frequent genetic events in many different carcinomas,
• such as in colon, breast skin , cervix and lung]. • The p53 gene negatively regulates cell cycle and
requires ‘‘loss of function’’ mutations for tumor formation
![Page 84: Cancer of the Cervix burden in southern africa and lesotho - sharing experiences](https://reader038.vdocuments.net/reader038/viewer/2022102602/554b685bb4c90551118b491a/html5/thumbnails/84.jpg)
• The normal function of p53 includes transient increase in expression after DNA damage occurs, leading to cell cycle arrest in the G1 phase.
• This arrest allows for repair of the DNA,or if repair is not possible, cells will undergo an apoptotic death.
• p53 acts through downstream regulators, such as p21,leading to inhibition of cyclin-dependent kinases, and eventually blocks Retinoblasoma (RB) gene phosphorylation pre-venting cell cycle progression
• It can lead to apoptosis through changes in levels of BAX and BCL-2 family members expression

The checkpoints are surveillance mechanism and quality control of the genome to maintain genomic integrity. Checkpoint failure often causes
mutations and genomic arrangements resulting in genetic instability.

CIN is common in HIV infected women because: HIV infected women likely to have persistent HPV Persistent infection leads to cervical cancer
Do ARTs Lower the Risk of Cervical Cancer? Multiple studies yield mixed results Incidence of cervical cancer appears to be unchanged in the
ART era Those on ART are more likely to have persistent HPV
So, probably no . . . therefore other treatment needed

risk
• Some Adenoviruses , HIV and, HPV E6 protein all can form a complex with and inactivate p53.
• E6 also stimulates p53 degradation through a selective ubiquitin-dependent proteolytic pathway( cascade reaction)
• The E6 proteins of high oncogenic risk types of HPV have higher affinity for p53 compared with the low-oncogenic risk types
![Page 90: Cancer of the Cervix burden in southern africa and lesotho - sharing experiences](https://reader038.vdocuments.net/reader038/viewer/2022102602/554b685bb4c90551118b491a/html5/thumbnails/90.jpg)
Advanced infection
• The rate of HIV production determines the amount of virus in the blood and this in turn, determines the rate of CD4+ cell destruction
• HIV accumulation eventually results in the destruction of lymph node architecture , the immune system –Military force and the release of virus and other previously trapped contents[fungi, TB, bacteria] into circulation
