1) This study analyzed 193 Saudi women diagnosed with epithelial ovarian cancer between 1997-2006 to characterize patients, tumor characteristics, treatment outcomes, and survival rates.
2) The majority of patients (67.4%) presented with late stage III or IV disease. Most tumors were high grade serous carcinoma (64.8%).
3) Despite high rates of intermarriage in Saudi society, only 2.1% of patients reported a family history of cancer. Higher parity (>10 pregnancies) was associated with improved progression-free survival.
4) Optimal debulking surgery and platinum-based chemotherapy resulted in a median progression-free survival of 22 and 11.9 months respectively. Advanced stage,

•The second most common gynecological cancer
• The most lethal gynecological cancer
•The life time risk of developing ovarian cancer in
women is 1 in 70
•The mean age of the diagnosis is mid-fifties
•The incidence increases with age up to 80 and then declines

5. Background:
According to the National Cancer Registry
in the Kingdom of Saudi Arabia, ovarian
cancer is the fifth most common cancer
diagnosed in women representing 4.9% of
all cancer cases diagnosed during 2010.
Detailed descriptive data regarding the
clinical course of this disease among Saudi
women is largely unknown.
6. 1. Saudi Medical Journal, 2002. Ovarian diseases in KAUH
• A study analysed 242 women underwent oophorectomy
• 72 ( 29.7%) cases Tumors
20 ( 14.4%) cases
Metastatic Carcinoma Papilary Serous Carcinoma
Until now no data published about EOC among Saudi women
7. •Saudi Arabia tumor registry Ovarian cancer( all types)
•6th the most common cancer among females in Saudi Arabia
•The most common H/P type Papillary Serous
Serous carcinoma
9. •Saudi society
•Intermarrieges
•Multiparity
Are our demographic, reproductive or environmental
features different than in the population of the rest of
the world and if they are;
how they affect behavior of EOC ?

Treatments rendered
21. Results:
. One hundred twenty-seven patients
(66%) experienced disease progression or
recurrence after primary therapy.
Median progression-free survival from
end of chemotherapy to
recurrence/progression was 11.9 months
(95% confidence interval, 9.4-15.2).
29. •The large majority of Saudi women with EOC present with
advanced stage disease
• Despite the high rate of imtermarriages, reported family
history of cancer was low in our study population
• High parity had no significant clinical impact on prognosis,
except more than 10 children
•The local Saudi data concur with the international data
Conclusion
30. Strengths:
this is the first study evaluating EOC in Saudi
patients.
central pathologic review of all cases
relatively large cohort of patients
31. Limitations:
Non-compliance in regular follow-up in our
gynecologic oncology clinics in up to 25% of patients
Inability to contact the patients from different
districts around Saudi Arabia.
The overall survival could not be
calculated/reported in this study owing to the lack
of accurate information available about the
patients’ date of death (if it occurred).
