Gynecological cancer in Indonesia

Abstract

To overview the status of gynecologic cancer in Indonesia. Information regarding Indonesia obtained from World Bank Report and Statistical Yearbook of Indonesia 2007, epidemiological data obtained from Histopathological Data of Cancer in Indonesia 2002, Department of Health-Registry Body of Indonesian Specialist of Pathology Association-Indonesian Cancer Society; Various Hospitals in big Cities in Indonesia. Indonesia is an Archipelago with a total area of 1,922,570.00 km2, the population is 222,192,000 (2006), the fourth world rank. Female is 49.86% with life expectancy 69 years. Gross National Product per Capita is 690.00 USD. Histopathological report in 2002 revealed that cervical cancer, ovarian cancer and uterine cancer were the most frequent cancer among female, which were the first (2,532 cases), the third (829 cases) and the eighth (316 cases) rank respectively. The peak age for cervical, uterine and ovarian cancer was 45-54 years. HPV 16, 18 were found in 82% of invasive cervical. Data from various academic hospitals in 2007 showed that cervical cancer is the most common malignancy followed by ovary, uterus, vulva and vagina. Five-year survival rate of stage I, II, III, IV cervical cancer were 50%, 40%, 20%, and 0% respectively. Overall five-year survival rate of carcinoma of the ovary was 54.8%. If sub-classified by stage, five-year survival rate are 94.3%, 75.0%, 31%, and 11.7% for stage I, II, III, and IV respectively. Five-year disease-free survival rate of endometrial cancer was 71.9%. Indonesia is the biggest Archipelago with a dense population but the income per capita still low (poor country). The most common gynecologic cancer is cervical cancer, followed by ovarian and uterine cancer. These cancers are included in top ten cancers in Indonesia. HPV 16, 18 were the most cause of cervical cancer. The five-year survival rates are comparable with world report.

INTRODUCTION

Cancer in Indonesia is positioned as the fifth of cause of death, due to increasing number of cancer patients year by year by the increasing life expectancy of Indonesian women. Life expectancy corresponds with the improvement of socioeconomic condition. More than 40% of female malignancies are gynecological cancers. Data about this in international publication is very rare or not appear. Therefore the purpose of this paper is to give information more about gynecological cancer in Indonesia.

DEMOGRAPHY

Indonesia is an archipelago with a big and dense populated area. The natural increase rate of population is still high since the birth rate is much greater than the death rate. The female population is slightly less than the male population, but the life expectancy of the female is longer than the male. Indonesia is categorized as a poor country or developing country especially after the economic crises hit Indonesia in 1998. The gross national product (GNP) and the personal GNP is lower among Asian countries (Table 1).

CANCER REGISTRY

Up to now, we do not have a body or institution of cancer registry such as in the developed country. What we have is a pathological cancer registry run by Indonesian Association of Anatomic Pathology in Collaboration with Indonesian Cancer Society. They collect the data from 13 laboratories of anatomic pathology spreading over several regions or provinces. While cancer data from hospitals is part of the disease reporting, reported by provinces and districts hospitals organized by Department of Health. Beside that Indonesian Society of Gynecologic Oncology now also develop a registry adopted from reporting system made by the International Federation of Gynecology and Obstetrics (FIGO). The reports come from academic hospitals where one or several gynecologic oncologists practice. An academic hospital is also as a top referral hospital at a respective region or province.

EPIDEMIOLOGY OF GYNECOLOGIC CANCER IN INDONESIA

1. Incidence

Since we do not have an established cancer registry, Department of Health assumes cancer incidence to be 100 per 100,000 people. Based on pathology, there were 10 most frequent cancer in male and female together i.e. cancer of the cervix, breast cancer, skin, rectum, nasopharynx, ovary, lymph nodes, colon, thyroid, and soft tissue. Cancer of the cervix also appears as the most frequent cancer among female, and its position was the first rank, followed by breast, ovary, skin, thyroid, rectum, lymph nodes, uterus, colon, nasopharynx.1,2 There were slight differences between pathological and hospital-based data (Table 2). Cancer of the cervix was about 75% among gynecological cancer and they were mostly diagnosed at advanced stages (Table 3).

2. Age

The peak age group in gynecologic cancer especially cervix, uterus and ovary was between 45-54 years old as shown in Table 4.

CERVICAL CANCER

1. Human Papilloma Virus

We have already known that Human Papilloma Virus as a causative agent of the lower genital tract malignancy, especially cancer of the cervix. We have biopsy specimens from 76 patients with cancer of the cervix, and HPV DNA was detected in around 96% and especially HPV 16 and 18 were found in 83%.3 This figure was only slight different from those found in Netherlands and Suriname (Table 5).

2. Risk factors

There was a hospital-based case control study at Dr Cipto Mangunkususmo Hospital (the top national referral hospital) that involved 143 cases of cervical cancer and 143 control cases. It reveals that risk factors in cervical cancer were age > 50 year, lower education, unemployment, age at first intercourse < 20 years, number of partners > 1, and parity ≥ 6 (Table 6).

SURVIVAL

It was very difficult to obtain 5-year survival rate nationally because our follow-up system is very poor. Many patients did not come regularly or failed to be followed up, or they frequently moved from one place to another place.

Studies of cervical, ovarian (178 cases) and endometrial cancer (72 cases) at the Dr Cipto Mangunkusumo Hospital found that the survivals at five years were as follow: 1) five-year survival rate in cervical cancer stage I, II, III, IV were 50%, 40%, 20% and 0% respectively. 2) Overall five-year survival rate of carcinoma of the ovary was 54.8%. If sub-classified by stage, five-year survival rates were 94.3%, 75.0%, 31% and 11.7% for stage I, stage II, stage III, and stage IV respectively. 3) Five-year relapse-free survival rate of endometrial cancer was 71.9%.

CANCER CONTROL PROGRAM

1. Program of Department of Health

Collaboration program JHPIEGO and Department of Health cover some regions in West Java, Central Java and East Java. This program consisted of training for the trainers and then trains the health providers such as general doctors, midwives and nurses. The activities are screening the women at risk at some region. The examination is with visual inspection with acetic acid (VIA).

2. See and Treat Program

This program is in collaboration with Female Cancer Program University of Leiden. The program initiated with three centers i.e. Jakarta, Tasikmalaya and Bali and then extended to North Sumatra, South Kalimantan and North Sulawesi.4 Table 7 shows the preliminary results. VIA positive rate was 4.5%, and as result, 1,346 of 1,556 women were treated. Therefore, the coverage in single visit is 86.5%.

SUMMARY

Indonesia is the biggest archipelago with a dense population but the income per capita still low (poor country). The most gynecologic cancer is cervical cancer, followed by ovary and uterine cancer. These cancers are included in the most ten cancers in Indonesia. The five-year survival rates are comparable with world report.
