Background: Cancer data from Rajasthan are limited. Only two studies, one from Western Rajasthan, and the other from Eastern Rajasthan have been published by Sharma et al. in 1992 and 1996. Aims: To put the cancer profile from this region in proper perspective, we conducted the present study on the patterns of various malignancies in Jaipur region, i.e., Eastern Rajasthan. Setting and Design and Material and Methods: The study spans over one and half decade (1990-2004) and is based on a retrospective six-year sample analysis of approximately 200,000 histopathological and cytological reports for the years 1990, 1991, 1996, 1999, 2001 and 2004. Results: A total of 21,868 cancers were recorded in the six sample years. There were 59.11% (12,926) males and 40.89% (8942) females, with the male to female ratio being 1.45:1. Organ wise, lung (8.45%), prostate (7.12%), brain (6.04%), urinary bladder (5.31%), esophagus (4.67%) and tongue (4.60%) are most common sites involved in males with regard to frequency, whereas breast (20.44%), cervix (14.99%), ovary (4.35%), brain (3.80%), esophagus (3.67%), uterus (3.01%) and rectum (2.80%) are common sites for malignancies in females. Conclusions: Significant findings were a higher frequency of cancers of the prostate, urinary bladder, and brain in males along with gall bladder cancers in females. Our figures have been compared with the national data.

| » Introduction|| |
Variable cancer pattern in different geographical regions may be dependent on genetic, environmental, dietary, social and other factors. It is important to know the differential disease pattern in a population subgroup. Limited data are available on cancer from Rajasthan. Only two studies, one from Western Rajasthan and the other from Eastern Rajasthan have been published by Sharma et al. in 1992 and 1996. , Recently, " Atlas More Details of Cancer" project of the National Cancer Registry Program (ICMR) 2001-2002 published data from Rajasthan.  Hence, to put the cancer profile from this region in a proper perspective we conducted the present study to determine the patterns of various malignancies in Jaipur region, i.e., Eastern Rajasthan.
In Rajasthan, the onus of diagnosis and treatment of cancer falls mainly on the six Medical College hospitals. The total population of the state as per 1991 census is 44,005,990. The population density of Rajasthan is 129/km 2 as compared to 274/km 2 in India. The per capita income is Rs. 2923.00. The female population is 48% as compared to 52% of males. The population growth rate is +28.44%. The overall literacy rate is 38.55%, with male literacy rate being 54.99% and female, 20.44%. The staple diet is bajra, jowar, maize and wheat. About 60.23% of the population resides in rural areas and agriculture is the mainstay of their livelihood. Sandstone, soapstone, silica sand, iron ore, china clay and limestone are the important minerals found here. The main industries are skin hide, blacksmithing, oil crushing, limestone, structural stone goods, textile printing, dyeing and finishing. The main addictions are tobacco in various forms, betel and nut, pan masala, alcohol, opium and bhang.
Jaipur is the capital of Rajasthan and is situated in Northwest India. It has a high-density population (336/km 2 ). Jaipur drains practically the whole of Eastern Rajasthan and neighboring states, as it is a tertiary referral center with all super specialties and very economical health care facilities, which cater to a population of approximately 13,451,881. Hence, the data obtained here are expected to be fairly representative of the overall incidence and pattern in this region.
| » Material and Methods|| |
The study spans over one and a half decade (1990-2004) and is based on retrospective six-year sample analysis of approximately 200,000 histopathology and cytological reports for years 1990, 1991, 1996, 1999, 2001 and 2004. Data were collected from various pathology centers in Jaipur region, Department of Pathology Medical College and private hospitals in Jaipur. To maintain the authenticity and reliability of data obtained, only those cases were recorded, which had microscopic verification of diagnosis. Overall site frequency and sex pattern were recorded. Classification of various malignant tumors was done according to the International Classification of Disease coding system by WHO (9th revision) using code number 140-208. A total of 21,868 cancers were recorded in the six sample years (1990, 1991, 1996, 1999, 2001 and 2004).
| » Results|| |
Out of approximately 200,000 histopathology and cytology records, which were studied during the selected six years from 1990 to 2004, a total of 21,868 new cancers were recorded [Table 1]. There were 59.11% (12926) males and 40.89% (8942) females, male to female ratio being 1.45:1.
Organ wise (in the order of frequency), lung (8.45%), prostate (7.12%), brain (6.04%), urinary bladder (5.31%), esophagus (4.67%) and tongue (4.60%) are the most common sites for malignancies in males, whereas breast (20.44%), cervix (14.99), ovary (4.35%), brain (3.80%), esophagus (3.67%), uterus (3.01%) and lymph nodes (2.81%) are the common sites for malignancies in females [Table 2].
The frequency of various systems involved was genitourinary system (20.79%), gastrointestinal tract (14.46%), head and neck (13.05%), respiratory tract (9.16%), breast (8.47%), hematological (7.35%), bones and connective tissues (4.21%), metastatic (2.29%) and others (20.22%).
The most noteworthy feature of the present study is that cancers of genitourinary system (20.79% of all malignancies) are the most common single group of cancers in both sexes. In males, genitourinary system formed 17.48% of all malignancies. Predominantly, prostate (7.12%) and urinary bladder (5.31%) were involved. When considered individually, prostate cancer formed 40.71% of all genitourinary cancers in males and urinary bladder formed 30.40%.
In females, genitourinary cancers formed 25.56% of all cancers. Cervix uteri (14.99%) and ovary (4.35%) were the major sites involved.
Urinary cancers formed 4.89%of all cancers (6.96% of all males and 1.89% of all females). Cancer of urinary bladder formed 5.31% of all cancers in males and 0.95% in females, whereas kidney cancers formed 1.65% in males and 0.94% in females.
Digestive tract (15.85%) is the second most common system involved. In males, it forms 16.29% and in females 15.21%. Esophagus (4.26%) formed the most common site among all gastrointestinal malignancies. It constituted 26% of all GI cancers (28.64% in males and 24.12% in females). Rectum was the second most common site of cancer in both sexes (20.05% in males and 18.38% in females). Stomach was third most common site of cancer in males (14.89%), but in females, gall bladder cancer was the third most common cancer (14.49%) followed by stomach cancer (9.93%). Esophagus, rectum, stomach, and colon formed about 77% of all gastrointestinal malignancies. Remaining sites together formed only about 23%.
System-wise analysis shows the gastrointestinal tract as second most common site following closely genitourinary tract, which is the most commonly involved organ system of body in this region. In other parts of the country, the gastrointestinal tract was the leading site of cancers.
Head and Neck Cancers
Head and neck cancers also ranked second being equal to digestive tract cancers. They formed 15.85% of all cancers. The malignancies of the oral cavity as a group were most common in head and neck cancers; they formed 7.06% of all cancers (8.84% in males and 4.48% in females). Tongue as an individual site (3.53% overall) was most common in head and neck group. In males, it formed 4.6% and in females 2.0%. Oropharynx (3.02%) was the next area to be involved (males 4.22% and females 1.29%) followed by Larynx 2.24% (males 3.24% and females 0.79%).
In the head and neck group, overall tongue formed 22.3% of all head and neck cancers (22.26% in males and 22.43% in females). Oropharynx formed 19.07% overall (males 22.46% and 14.41% in females) followed by Larynx, which formed 14.13% of all head and neck cancers (males 15.7% and females 8.9%). Hypopharynx formed the fourth most common site 11.77% overall but it formed the third most common site in females (10.65%), whereas in males, the third most common site was the larynx followed by hypopharynx.
Respiratory Tract Malignancies
Carcinoma lung is the most common site (8.45% in males, 1.64% in females), with a large male to female ratio. If nasal cavity, nasopharynx and larynx (carcinoma larynx males 3.24%, females 0.79%) are included, then respiratory tract cancers form 9.16% of all cancers (13.09% in males and 3.48%in females). This makes it the fourth most common system involved.
As a group, hematological malignancies formed the fifth most common site involved, i.e., 8.84% of all malignancies in both sexes (in males 10.45% and in females 6.52%).
In this group, myeloid leukemia was the most common type. It formed 23.53% in both sexes combined (in males 22.80% and in females 25.21%). It is followed by non-Hodgkin's lymphoma. This formed 19.70% of hematological malignancies in males and females combined together (in males 20.58% and in females 17.67%). In females, it is the third most common type, whereas in males it is the second most common. The third most common type is lymphoid leukemia in both sexes combined 19.03% (in males 18.58% and in females 20.07%).
Malignancies of the breast form the sixth most common site of carcinoma in both sexes combined (i.e., 8.47% of all malignancies). In females, it is the most common site of malignancy (20.44%), whereas in males it constitutes only 0.19%.
Malignancies of the brain form the seventh most common site having a frequency of 5.13% in both sexes combined (in males 6.04% and females 3.80%). In males, malignancies of brain as an individual site form the third most common site involved in the body, whereas in females it is the fourth most common site in the whole body.
Bone and Connective Tissues
This is the eighth most common system involved in both sexes combined. It forms 4.21% of all malignancies (4.54% in males and 3.74% in females).
| » Discussion|| |
There are several limitations in describing patterns of cancers in individual centers, especially in the context of geographical distribution. The leading sites of cancers in a given place are dependent on a number of factors. The popularity of a particular department or treating physician, the accessibility of a particular diagnostic or treatment facility, affordability of patients and so on. In some centers, one could be dealing with small number of cancers. Thus, either the order of leading sites or fluctuation of the same between the years provides little meaning. Still, the patterns observed in most cancer centers that function as referral institutions for care of cancer patients do reflect the predominant cancers in the region. Further, they give an indication of the magnitude and burden of cancer in specific institution or region.
Our study spans over almost one and a half decade including sample analysis of approximately 200,000 histopathologies, although we have taken data-based cytological reports for the years 1990, 1991, 1996, 1999, 2001 and 2004.
Ten leading cancer sites in both sexes are compared with the incidence of cancer from population-based studies conducted in different parts of the country [Table 3],[Table 4].
Cancer in Males
Cancer of the lung was the leading site of cancer in males in present study (8.45%). It was also the leading site in males in Bikaner (8.63%). Lung cancer as leading site of Cancer in males was also reported from Karunagoppally (18.0 %), Bhopal (12.0%), Delhi (9.9%) and Mumbai (9.2%).

| » Comments|| |
The most significant observation was the high frequency of gall bladder cancer and CNS/brain malignancies in females and higher frequency of prostate, urinary bladder and CNS/brain cancers in males. Although the database used in this study is lacking completeness in various aspects, it gives an idea of distribution of various cancers reported in this region. Stress needs to be laid on compilation of figures from various parts of the country so that a comprehensive national database could be obtained.
