Background:Indo-Gangetic basin is known to have higher incidence of gallbladder cancer. Proximity to River Ganga and high heavy metal in soil exposure have been postulated as risk factors.Aim:This study aims to evaluate the geographical pattern of gallbladder cancer from consecutive patient database enrolled in hospital-based cancer registry (HBCR).Objectives:To evaluate demographic profile and districtwise/zonewise dispersion of gallbladder cancer cases registered in HBCR from year 2014 to 2016. To evaluate association of carcinoma gallbladder (CaGB) due to proximity of Ganges, districts of high soil arsenic levels and referral bias.Materials and Methods:Demographic profile and district-based location of individual consecutive gallbladder cancer patient registered in Regional Cancer Centre from the year 2014 till 2016 were analyzed. Population data from 2011 census and arsenic soil content data from central groundwater body were obtained. Frequency distribution, cross tabulation, and odds ratio were used to analyze risk of CaGB across population subsets in Bihar.Results:A total of 1291 consecutive patients of CaGB were registered from 2014 to 2016. Median age at diagnosis was 55 years (range 18–95 years). Male to female ratio was 0.6. Patna (16%) followed by Vaishali (5.8%), Sitamarhi (5%), Madhubani (4.7%), Gaya (4%), and Samastipur (4%) had highest cases. Districts along main central River Ganga (n = 12) and those exposed to high arsenic soil content (n = 15) had higher odds ratio for CaGB, 1.72 (95% confidence interval [CI]: 1.54–1.91, P = 0.001), and 1.45 (95% CI: 1.30–1.62, P = 0.001), respectively. Districts within 100 km radius of our institute had higher gallbladder cancer cases, odds ratio 1.81 (95% CI: 1.62–2.03, P = 0.001), suggesting significant referral bias predominantly contributed by cases registered under Patna and Vaishali districts.Conclusion:CaGB is major public health problem in Bihar. Exposure to high soil arsenic levels and proximity to River Ganga are strongly associated with gallbladder cancer. Systematic population-based longitudinal studies are needed to explore above hypothesis.

A malignant melanoma is a highly lethal melanocytic neoplasm. A neoplasm usually affects the skin. Malignant melanomas in the head and neck region are rare, accounting for less than 1% of all melanomas. Malignant melanoma of the nose and paranasal sinuses is an aggressive disease typically presenting at an advanced stage, with a 5-year survival rate ranging 20-30%. Melanomas are tumors arising from melanocytes, which are neuroectodermally derived cells located in the basal layers of the skin. This is a case report of a 35-year-old male, who presented with very aggressive disease and developed liver metastasis.

Background:Trends of cancer cases vary across several hospital-based cancer registries (HBCRs). There is a paucity of demographic data to evaluate trends of cancer in Eastern India.Aim:The aim of this study is to evaluate trends and pattern of cancer cases with respect to time from HBCR from Bihar.Objectives:The objective of this study is to evaluate the numbers of consecutive patients registered with eight most common type of cancer in our HBCR in Regional Cancer Centre, Bihar, and to evaluate trends of cancer cases registered with respect to time.Materials and Methods:Demographic profile of consecutive cancer patients registered from January 2014 to December 2016 (3 years) in HBCR was obtained. Patients diagnosed with common malignancies including head-and-neck cancer, gallbladder, breast, cervix, ovary, esophagus, stomach, hematolymphoid, and colorectal were analyzed. Frequency distribution, crosstabs, and line diagram were used to evaluate the trends of these common cancers with respect to time.Results:Sixty-six thousand and twenty-nine consecutive patients were registered between 2014 and 2016. Carcinoma gallbladder was the most common malignancy (21%), followed by head-and-neck cancer (19%) and breast cancer (15%). Median age at the diagnosis was 55 years for carcinoma gallbladder while 53 years and 46 years for head-and-neck and breast cancer, respectively. Male-to-female ratio was 0.6 for carcinoma gallbladder and 1.8 for head-and-neck cancer. A number of gallbladder and head-and-neck cancer registered increased by 36% (between 2014 and 2015) and 5% (between 2015 and 2016) and 24% (between 2014 and 2015) and 4% (between 2015 and 2016), respectively. Carcinoma breast and cervix showed decreasing trend with fall in registration up to 13% (between 2015 and 2016) and 27% (between 2015 and 2016), respectively.Conclusion:Carcinoma gallbladder is the most common cancer in Bihar. Head-and-neck cancer and carcinoma gallbladder are increasing while breast and cervical cancers are decreasing with respect to time.

Extranodal NK/T-cell lymphoma, nasal type (ENKL) is a rare lymphoid neoplasm that in the past has been grouped with a variety of granulomatous diseases. ENKL occurs in all age groups. However, it seems to occur more often in people in their 50s and affects more men than women. It is strongly linked to the Epstein-Barr virus (EBV), especially in people of Asian countries. Because this type of lymphoma occurs in organs or tissues other than lymph nodes, it is called ENKL. This is a case report of a 25-year-old female patient who presented with a nonhealing ulcer at the right nasal ala involving the upper lip and cheek for the last 2 months, which had been treated with antitubercular treatment without success. After biopsy and immunohistochemical (IHC) analysis, the patient had been diagnosed a case of extranodal T-cell lymphoma.
