Khandekar and Yedshikar: Histopathological spectrum of neoplastic lesions: A two year study


Cancer has been a scourge on the human population for many years. With changing lifestyle, improved longevity and better control of infectious diseases, non-communicable diseases like cancer have emerged as major health problems worldwide, more so in developing countries.1, 2 The burden of cancer is growing, and it is one of the leading causes of death worldwide. Every year nearly 10 million people are being diagnosed with cancer out of which about 6 million die per year.3

Globally lung, stomach and colorectal cancers are the leading cancers in males, whereas, breast, lungs and stomach cancer constitute top three leading cancers in females.4 In Indian population, all types of cancers have been reported. The top five cancers among men are lung, head and neck region (mouth, tongue and larynx), colorectum and oesophagus while among women - breast, cervix, ovary, oral cavity and uterine cancer are most common.5 There is significant geographical variation in the incidence of cancer in India. Incidence, pattern, histopathological variants of neoplastic lesions are an important aspect for knowing the magnitude and nature of cancer in a particular area.6 Hence, the present study was undertaken to know the status of various types of cancers in Rural Tertiary Care Hospital at Yavatmal district in the Vidharbha region of the Western State of Maharashtra.

Materials and Methods

The present retrospective study was carried out at Tertiary Care Hospital for the period of two years from October 2016 to November 2018. This tertiary level teaching hospital situated in rural area of Yavatmal district of western Maharashtra and the study population was mainly from places around Yavatmal. A proforma was used to collect data such as age, sex and place of residence. Percentages for parameters such as age distribution to gender wise, system wise, organ wise were recorded. A detail history was taken, diagnosis, primary site, morphology of neoplastic lesions and histopathological examination of all the specimens were done during the study period. We have not received specimens of CNS, liver, heart, mediastinal masses, as we don’t have super specialty, these operative procedures are not carried out.

Observations and Results

During two years of study period, total of 3608 specimens were examined among them 724 cases had neoplastic lesions in which 205 (28.31%) were males and 519 (71.68%) were females. Out of 724 neoplastic lesions, 499 (68.92%) cases were benign and 225 (31.07%) cases were malignant. The majority (60; 26.66) of malignancy cases were in the age group of 61-70 years followed by 51-60 years (52; 23.11%) as shown inTable 1.

A general way of assessing the dimension of the cancer problem in a given cancer hospital/centre is the number of cancer diagnoses per year in the concerned hospital. It is observed that cancers are increasingly seen in both genders and all the age groups due to a complex interaction of various risk factors.7 Studies on incidence or risk for development of the disease pattern provide useful summary of disease burden. Several studies reported trends in cancer incidence for various sites.8, 9 In present study, histopathological spectrums of neoplastic lesions were study. Total 724 cases had neoplastic lesions out of which, 499 cases were benign and 225 cases were malignant. Similarly Mankar and Sonawane study the spectrum of neoplastic lesions in North West Maharashtra.6 In their study, total 759 cases had neoplastic lesions of which 559 were benign and 200 cases were malignant. The minimum age of patient was 8 year female with ovarian germ cell tumor and the maximum age was 84 year old male with prostatic adenocarcinoma. Out of 724 cases, 205 cases (28.31%) were male and 519 (71.68%), were female patients, it was clearly reprehensive that there was female preponderance in the study. It is because of more cancers of female genital organs, breast and thyroid malignancies along with high incidence of oral cancers. Malhotra et al found that females outnumbered males in the incidence of cancer, with male to female ratio being 1:1.09 in Ludhiana, Punjab.10 Talukder et al also reported female preponderance in their study; this study was carried out at National Institute of Cancer Research and Hospital (NICRH), Bangladesh.11 The age standardized rates (ASR) for cancer (all sites) in Hyderabad, Pakistan were 91.6/100,000 in males and 96.0/100,000 in females.12 In contrast to our study Mehrotra et al reported male predominance with male: female ratio of 1.5:1 in the Allahabad region of North India.13

Presently, oral cancer is the fourth common type of malignancy after lung, stomach and liver in males. It is the fifth common cancer after cervix, breast, stomach and lung cancer in females.14 In current study oral cancer was most commonly reported malignant tumor, out of 47 oral cancers, 25 were male and 22 were female which was also seen in younger population, minimum being 24 years. Higher prevalence and early age of presentation of oral cancers is due to increased tobacco use in one form or other in rural areas of India starting at an early age which is comparable with previous studies.6, 7, 13 Regional Cancer Centre (RCC) Kerala reported about 14% oral cancer patients out of which 17.0 and 10.5% cases were in males and females, respectively.15

Earlier cervical cancer was most common cancer in Indian woman but now the incidence of breast cancer has surpassed cervical cancer and is leading cause of cancer death, although cervical cancer still remains most common in rural India.16 However, cancers, namely those of oral and lungs in males and cervix and breast in females, account for over 50% of all cancer deaths in India.17 In present study, carcinoma of breast and cervix were predominant cancers in females, comparable with the study done by Mankar and Sonawane,6 Bhurgri et al13 and Bhagyalakshmi et al.18 Nulliparity and late age at first birth are the most consistently observed risk factors for breast cancer.19, 20 Women who start menstruating early in life or have a late menopause also have an increased risk of developing breast cancer.21 Whereas, early marriage, lower socioeconomic status of women, education, age at first childbirth and multiparity among the local population are important risk factors for cervical cancer. The increased awareness and education of families at grass root level, regular Pap smear examination of perimenopausal women and health camps arrangement has immensely helped to reduce the incidence of carcinoma of cervix in our scenario.6

Out of 22 cases of gastrointestinal tract cancers 10 were male and 12 were female which is comparable with previous studies.18, 22 Kalyani et al23 study the cancer profile at Kolar, Karnataka based on Pathology Department records and they reported predominance of upper gastrointestinal cancers in both genders. Leiomyoma of uterus comprised of 21.44% and carcinoma of thyroid in 11.95% with female preponderance. Incidence of carcinoma of prostate and skin was 8.72% and 8.40% respectively. The commonest benign lesions in males were lipoma and prostate. These findings are correlated well with the study done by Mankar and Sonawane.6 Darkly pigmented skin, chronic scarring and areas of chronic inflammation seen in farmers could be the cause for higher incidence in our setup.


In the present study, incidence of neoplastic lesions was predominant in females. In both the gender oral malignancies was the commonest, also in males’ gastrointestinal tract malignancies and in females’ carcinoma of breast and cervix were the most frequent malignancies. Commonest benign lesions in males were lipoma and prostate while female genital tract and breast in females. The prevalence of cancer in present study is due to lack of awareness among people, self-neglect, late presentation, prevalent tobacco and alcohol use and limited resources. However this study provide leads for further etiological research, identify cancers that are more common in rural area and helps to take-up cancer preventive measures and screening programmes in early detection of cancer. Understanding cancer magnitude, risk and trends will be of help in cancer control in future.
