Role of palliative SBRT in barcelona clinic liver cancer-stage C hepatocellular carcinoma patients.

OBJECTIVE: To evaluate the role of palliative stereotactic body radiation therapy (SBRT) in Barcelona Clinic Liver Cancer stage­C (BCLC-C) hepatocellular carcinoma (HCC) patients who are not suitable for other loco-regional therapies. MATERIALS AND METHODS: It is an observational retrospective study done between May 2020 and September 2021. The data were collected from 35 patients of advanced HCC who underwent SBRT. Patients of Child Pugh status (CPs) A5-B7 and with a liver reserve of ≥ 700cc were included. Local control (LC), overall survival (OS) and adverse events including decompensation were carefully recorded. RESULTS: In the cohort, Portal vein and IVC tumor thrombosis were present in 33 (94.3%) and 8 (22.85%) patients, respectively. Lung and nodal metastasis were found in 11 (31.4%) and 21 (60%) of patients, respectively. The median gross tumor volume (GTV) was 563cc (range 80-1925cc). The median SBRT dose prescription was 35 Gy (range 25-40 Gy) in 5-10 fractions. Post radiation therapy, there was improvement in pain and discomfort in 24 out of 29 (82.75%) and 18 out of 23 (78%) patients respectively. Also bone metastasis related pain was improved in all 3 (100%) patients. One year LC, and OS were 80% and 30% respectively. On multivariate analysis, the GTV volume > 750cc and PIVKA-II > 8000 mAU/ml remained the predictor factor for poor OS. Post SBRT, change in child-pugh score by 1 point was observed in 7 patients (20%) which was managed conservatively. CONCLUSION: SBRT is a safe and feasible option for BCLC­C HCC. It not only improves the quality of life by symptom control but also results in good LC and OS with acceptable toxicity. SBRT should be considered in a multidisciplinary fashion for patients presenting with advanced HCCs.

Comparative RNA isolation methods from fresh ejaculated spermatozoa in Sahiwal cattle (Bos indicus) and Murrah buffalo (Bubalus bubalis) bulls for high quality and enhanced RNA yield.

Sperm mRNA transcriptional profiling can be used to evaluate the fertility of breeding bulls. The aim of the study was to compare the modified RNA isolation methods for higher RNA yield and quality from freshly ejaculated sperm of cattle and buffalo bulls. Ten fresh ejaculates from each Sahiwal (n = 10 bulls × 10 ejaculates) and Murrah bulls (n = 10 bulls x 10 ejaculates) were used for RNA isolation. From the recovered live sperm, total sperm RNA was isolated by conventional methods (TRIzol, Double TRIzol), membrane-based methods combined with TRIzol (RNeasy + TRIzol) with the addition of ß-mercaptoethanol (BME) and Kit (RNeasy mini) methods in fresh semen. Among different isolation methods; the membrane-based modified methods combined with TRIzol (RNeasy + TRIzol) with the addition of ß-mercaptoethanol (BME) resulted significantly (p < .05) higher total RNA quantity (300-340 ng/µL) and better purity in different concentrations of spermatozoa viz., 30-40 million, 70-80 million and 300-400 million sperm. The study concluded that the inclusion of BME to the combined membrane-based methods with somatic cell lysis buffer solution was best for constant increased yield and purity of RNA isolation from Sahiwal cattle and Murrah buffalo bull sperm.

Cholesterol-loaded cyclodextrin attenuates dilution effect and improves quality of bovine low sperm insemination doses during cryopreservation.

In the present study, the effect of cholesterol-loaded cyclodextrin (CLC) on the quality of low sperm doses at post-thaw was evaluated. Twenty four ejaculates (6 from each bull) were collected and split into eight aliquots. First four aliquots were diluted up to 20-, 15-, 10- and 5-million sperm/0.25 ml, and remaining four were treated with CLC at the rate of 1 mg/120 million spermatozoa, followed by dilution up to 20-, 15-, 10- and 5-million sperm/0.25 ml. The diluted semen was equilibrated, cryopreserved and evaluated post-thaw. The averages of total motility, progressive motility, average path velocity, straight linear velocity, membrane intact spermatozoa and noncapacitated spermatozoa were higher (p < .05) in CLC-treated sperm doses compared to control ones. However, the moribund spermatozoa, capacitated spermatozoa and acrosome-reacted spermatozoa were reduced (p < .05) in CLC-treated spermatozoa compared to control. The curvilinear velocity and linearity did not differ (p > .05) between control and CLC-treated sperm doses. In conclusion, treatment of spermatozoa with CLC at the rate of 1 mg/120 million spermatozoon attenuates the dilution effect and improves the quality of bovine low sperm insemination doses during cryopreservation; hence it could be a favourable cryoprotectant for preserving bovine semen at higher dilutions.

Efficacy and toxicity of SBRT in advanced hepatocellular carcinoma with portal vein tumor thrombosis - a retrospective study.

BACKGROUND: The purpose of this study was to evaluate the outcome of stereotactic body radiation therapy (SBRT) in patients of unresectable hepatocellular carcinoma (HCC ) complicated with portal vein tumor thrombosis (PVTT) who are also unsuitable for other locoregional therapies. MATERIALS AND METHODS: Between May 2018 and January 2020, twenty-nine patients with advanced unresectable HCC s, treated with SBRT, were enrolled in this retrospective audit. Patients of Child status A5-B7 and with healthy liver volume, ≥ 700 ccs were treated. Local control (LC), overall survival (OS), progression-free survival (PFS), PVTT opening rate, and effect of prognostic factors were analyzed. RESULTS: The median tumor diameter was 8.6 cm (5-14), and the median tumor volume was 275 cc (151-1196). The median SBRT dose prescription was 48 Gy in 6 fractions (32-50 Gy in 5-6 fractions). The median follow up was eight months (1-20), 1-year local control, progression-free survival, and overall survival were 95%, 53.4%, and 60%, respectively. Overall rate of grade III toxicity was less than 5%, and the most common toxicity was lymphocytopenia. Tumors of more than 350cc had worse OS and PFS when compared to tumors < 350 cc (median OS and PFS of tumors > 350 cc was 4 months and two months, p = .01 and .003, respectively). A total of fifteen patients progressed with the disease and the median time to progression was two months [1-4]. CONCLUSION: SBRT is safe and provides excellent local control in advanced HCC complicated with PVTT. The out of field failure pattern and time to failure in these patients highlights the need for adjuvant systemic therapy after completion of local treatment. Our data warrant the need for multimodality trials in this patient cohort.

Feasibility of 4D CT simulation with synchronized intravenous contrast injection in hepatocellular carcinoma.

BACKGROUND: Delivering Stereotactic Body Radiotherapy (SBRT) for Hepatocellular Carcinoma (HCC) is challenging mainly for two reasons: first, motion of the liver occurs in six degrees of freedom and, second, delineation of the tumor is difficult owing to a similar density of HCC to that of the adjoining healthy liver tissue in a non-contrast CT scan. To overcome both these challenges simultaneously, we performed a feasibility study to synchronize intravenous contrast to obtain an arterial and a delayed phase 4D CT. MATERIALS AND METHODS: We included seven HCC patients of planned for SBRT. 4D CT simulation was performed with synchronized intravenous contrast based on the formula TSCAN DELAY = T peak - (L0/Detector Coverage × Cine Duration in Seconds). This was followed by a delayed 4D CT scan. RESULTS: We found that, with our protocol, it is feasible to obtain a 4DCT with an arterial and a delayed phase making it comparable to a diagnostic multi-phase CT. The peak HU of the 4D scan and diagnostic CT were similar (mean peak HU 134.2 vs 143.1, p value = 0.58 N.S). Whereas in comparison with a non-contrast CT a significant rise in the peak HU was seen (mean peak 134.2 vs 61.4 p value = .00003). CONCLUSION: A synchronized contrast 4D CT simulation for HCC is safe and feasible. It results in good contrast enhancement comparable to a diagnostic 3D contrast CT scan.

Sperm protein carbonylation.

The cryopreservation of sperm is a well established technique that plays an essential role in dissemination of elite germplasm of livestock. Despite having numerous advantages, the cryopreservation induces certain stresses on sperm including structural and functional damages leading to impaired sperm quality and fertility, which might be associated with production of reactive oxygen species (ROS). In addition, the ROS upon reacting with sperm lipids, DNA and proteins may lead to a cascade of sperm damages. The sperm membrane contains a rich amount of polyunsaturated fatty acids, which increases their susceptibility to oxidative stress induced damages, leading to formation of secondary products. These secondary products result in oxidation of sperm proteins via carbonylation. The carbonylation could lead to disturbances in specific proteins that are involved in capacitation. The present review deals with sperm protein carbonylation.

Treatment Response and Survival with Chemotherapy for Unresectable, Nonmetastatic Cholangiocarcinoma.

Background and objectives: Limited studies have dwelt upon the treatment of unresectable, nonmetastatic cholangiocarcinoma as a separate entity. Hence, the management protocols are not clearly defined for this subgroup of patients. We aimed to analyze patients treated for unresectable, nonmetastatic cholangiocarcinoma. Materials and methods: We analyzed the treatment of patients with unresectable, nonmetastatic cholangiocarcinoma retrospectively. Results: A total of 162 cases of cholangiocarcinoma were reported to our center from 2016 to 2019, out of which 54 were unresectable and nonmetastatic. Thirty patients opted for treatment and were the subjects of this study. Of 30 patients, 24 had hyperbilirubinemia, out of which 10 received chemotherapy after biliary drainage procedure. Out of 30 patients, a total of 16 patients had received chemotherapy, while 14 did not. Gemcitabine/Cisplatin was the first-line chemotherapy administered to 9 patients, whereas 5 received Gemcitabine/Capecitabine and 2 received single-agent gemcitabine. Partial response was documented in 6 patients, and 4 patients had stable disease. The median overall survival was 12.04 months in patients who had received chemotherapy and 6.02 months in those who did not receive chemotherapy (p = 0.005). The median progression-free survival was 6.53 months for patients who had received chemotherapy. The aHR for mortality with chemotherapy compared with no chemotherapy was 0.353 (95% CI: 0.154-0.807). Conclusion: The study data demonstrate that gemcitabine combined with cisplatin- or capecitabine-based chemotherapy prolongs survival in patients with unresectable and nonmetastatic cholangiocarcinoma. In patients with cholangiocarcinoma associated with jaundice, biliary drainage procedure enables giving chemotherapy. Hyperbilirubinemia persisting despite drainage procedures portends poor prognosis and represents an unmet need. How to cite this article: Gupta A, Sahai P, Prasad M, et al.

Role of stereotactic body radiotherapy for inferior vena cava tumour thrombus in hepatocellular carcinoma.

INTRODUCTION: To evaluate the role of stereotactic body radiotherapy (SBRT) in hepatocellular carcinoma (HCC) patients with inferior vena cava tumour thrombus (IVCTT) who are not suitable for other loco-regional therapies. METHODS: This is an observational retrospective study done between May 2020 and April 2022. The data of 17 patients who underwent SBRT were collected. Patients of Child-Pugh score (CPS) A5-B7 and along with a liver reserve of ≥700 cc were included. Local control (LC), overall survival (OS) and adverse events including hepatic decompensation were carefully recorded. RESULTS: In the cohort, the tumour thrombus was extended to the right atrium in nine (52.9%) patients, and regional nodal and lung were found in 60% and 31.4% of patients respectively. The median gross tumour volume (GTV) was 745 cc (107-1,650 cc). The median SBRT dose prescription was 35 Gy (25-45 Gy) in 5-10 fractions. At 6 months, LC and OS were 80% and 75% respectively. On multivariate analysis, an ALBI score >-2.36 was found to be the predictor for the poor OS. Post-SBRT, a change in CPs by 2 points was observed in one patient (5.9%) which was managed conservatively. Post-radiation, improvement in pain and discomfort was observed in 92.3% and 87% of patients, respectively and bone metastasis related pain was also resolved. CONCLUSION: Stereotactic body radiotherapy is a safe and feasible option for HCC patients with IVC and right atrium tumour thrombosis. It not only improves the quality of life but also results in good LC and OS with acceptable toxicity. SBRT should be considered in a multidisciplinary fashion for patients presenting with tumour thrombosis extending to IVC and the right atrium.

18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in a Rare Case of Epithelioid Hemangioendothelioma - A Diagnostic Challenge.

Our case highlights the 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan findings in a rare case of biopsy-proven epithelioid hemangioendothelioma (EHE) in a 66-year-old woman with multi-organ involvement (lung, liver, and bone) who was subsequently treated with palliative radiation therapy and oral pazopanib. Furthermore, follow-up 18F-FDG PET/CT findings are detailed. EHE is a rare malignant vascular neoplasm (<1% of all vascular tumors) with an epithelioid and histiocytoid appearance arising from the vascular endothelial and preendothelial cells.

To Evaluate the Role of Positron Emission Tomography-Computerized Tomography in Initial Staging of Carcinoma Breast.

BACKGROUND: Breast cancer is the most common cancer in urban and second common in rural Indian women. In India, in spite of the best treatment available being given to the patients they lose their lives because of paucity of diagnostic aids and lack of an organized breast cancer screening program. Early detection, accurate staging, and initiation of appropriate therapy are the key factors for improving the treatment outcome and prognosis of the disease for the patients. Traditional staging methods include clinical examination, blood tests, chest X-ray, ultrasound of the abdomen, and/or skeletal survey. As these tests lack sensitivity and specificity, these are being scaled down. The hybrid positron emission tomography-computerized tomography (PET-CT) is a unique tool in the field of imaging modalities that combines the effectiveness of PET and CT. This study was undertaken to assess the efficacy and accuracy of PET-CT as a single-session staging modality in the very initial stage itself and if it can replace the conventional means of staging. METHODS: This was a cross-sectional study conducted in the Radiotherapy department at GGS Medical College and Hospital Faridkot from March 2014 to October 2015. 52 patients with newly diagnosed and histopathologically proven carcinoma breast were staged by conventional modalities (clinical examination, blood tests, X-ray chest, mammography, ultrasonography abdomen, skeletal survey) and by 18F-fluorodeoxyglucose (18F FDG) PET/CT. PET-CT images were used for the detection, localization, staging of tumors and detection, evaluation, and diagnosis of metastatic lesions, disease burden and organ function along with treatment planning and planning therapeutic procedures. Following the completion of initial study, the results of 18F FDG PET-CT staging in comparison with conventional staging method were assessed. Along with this, the accuracy, changes in staging of cases of carcinoma breast and cost-effectiveness of 18F-FDG PET-CT were also studied. RESULTS: All the pathologic entities identified by conventional imaging were also perceived with 18F-FDG PET/CT. Therefore, we recommend the use of PET/CT as an important imaging modality for initial diagnosis of carcinoma breast.

Functional and biochemical changes in the thyroid gland following exposure to therapeutic doses of external beam radiotherapy in the head-and-neck cancer patients.

CONTEXT: Majority of the head-and-neck cancers are locoregionally advanced at the time of diagnosis. Hence, radiotherapy (RT) portals will invariably cover the whole neck and thus, the thyroid gland which may lead to its dysfunction. AIMS: The purpose of this study is to identify the functional and biochemical changes in the thyroid gland following RT to the neck using single-photon emission computed tomography-computed tomography (SPECT-CT) and thyroid function tests (TFTs). SUBJECTS AND METHODS: In this prospective study, 45 patients of the head-and-neck cancer, receiving RT with or without chemotherapy were investigated. Baseline TFTs and thyroid scans (on SPECT-CT) were done, and the same were repeated at the completion of RT, at 3 and 6 months. RESULTS: All patients received a minimum of 30 Gy to the whole neck. Baseline TFTs and thyroid scans were normal. None of them developed hypothyroidism clinical or subclinical (C/S) at the completion of RT. Six patients developed hypothyroidism (four subclinical, two clinical) at 3 months of the completion of treatment. At 6 months of follow-up 14 patients (31.1%) developed hypothyroidism (ten subclinical, four clinical) with P≤ 0.01. All patients having clinical or subclinical hypothyroidism had decreased uptake on thyroid scan. Patients having decreased uptake on thyroid scan only, with normal TFTs and no symptoms of hypothyroidism were zero at the completion of RT, 1 at 3 months follow-up, and seven at 6 months follow-up. CONCLUSIONS: Hypothyroidism (C/S) is an under-recognized but significant complication of therapeutic doses of RT to the neck. In our study, we recognized hypothyroidism as early as 3 months following the completion of RT. Hence, tests to evaluate functional and biochemical changes in the thyroid gland should be instituted as early as 3 months following RT.

Modification of French mini-straw plug position for cryopreservation of small doses of bull sperm.

Greater than optimal diluting of semen for producing a large number of doses containing relatively small numbers of sperm can lead to compromised quality of sperm, post-thawing. In the present study the French mini-straw plug position was modified and the effect of re-positioning was evaluated on the quality of sperm after thawing subsequent to cryopreservation of small doses of sperm. Four types of mini-straws were used based on the position of cotton plug including no plug displacement (Type 1; Manufacturers location for plug-placement in 0.25 mL French mini-straws), and Type II, III, and IV with re-positioning the cotton plug being 2.5, 5, and 7.5 cm, respectively, further from the manufacturer's placement location. Each ejaculate was proportioned into four Aliquots (I, II, III, and IV) and diluted to 80, 60, 40, and 20, million sperm/mL, respectively. Aliquot I was placed in all types of straws, while Aliquots II, III, IV were placed only in Type I straws. Semen straws were equilibrated, cryopreserved and sperm kinetic and functional variables were evaluated post-thawing. The results indicate that in Aliquots III and IV there were lesser (P < 0.05) values for sperm kinetic and function variables compared with sperm from Aliquot I (i.e., unmodified mini-straw). In conclusion, cryopreservation of small doses of sperm in modified French mini-straws resulted in acceptable values for kinetic and function variables, post-thawing.

Modulation of voltage-gated sodium channels induces capacitation in bull spermatozoa through phosphorylation of tyrosine containing proteins.

In our previous study, we have reported the molecular presence of Nav 1.8 in bull spermatozoa and its potential involvement in regulation of sperm functions. With the selective blocking of Nav 1.8 using A-803467, alterations in sperm functions were observed, therefore, we envisaged of investigating the involvement of Nav in regulating sperm function and the mechanism(s) involved in it using veratridine, a selective opener of Nav channels. Forty ejaculates were collected from four Hariana bulls and semen samples were pooled in view of the non-significant variations between the different ejaculates. Treatment of sperm cells with veratridine (6, 8, and 10 µM) resulted in concentration- and time-dependent increase in forward progressive sperm motility and it persisted up to 6 h. However, hyperactive motility was induced by veratridine at higher concentrations (8 and 10 µM) and after 2 h of incubation, which was confirmed by subjective assessment followed by chlortetracycline staining showing the increased B-pattern spermatozoa, and thereby suggesting the involvement of Nav in regulation of capacitation in spermatozoa. To substantiate the functional study observations especially veratridine-induced capacitation, immunoblotting and indirect immune fluorescence assays were performed for detection of the tyrosine-phosphorylated proteins. The immune blot study revealed the presence of five tyrosine phosphorylated proteins, namely-p17, p30, p54, p90 and p100. The p17 protein showed the highest band intensity compared to other protein bands indicating its potential involvement in the process of capacitation. Immunolocalization study revealed positive immunoreactivity for tyrosine phosphorylated proteins in the middle piece, post acrosomal region (high fluorescence) and tail of the spermatozoa (low fluorescence). From the results of present study, it is evident that activation of NaV by veratridine, especially at higher concentrations, induced capacitation which is evidently mediated through phosphorylation of the tyrosine containing proteins localized in the post acrosomal regions, middle piece and tail of the spermatozoa. However, further studies will help in unraveling the involvement of Nav and other ion channels regulating different physiological functions of sperm.

Effect of reduced glutathione supplementation in semen extender on tyrosine phosphorylation and apoptosis like changes in frozen thawed Hariana bull spermatozoa.

To provide new insights into the mechanisms through which reduced glutathione (GSH) is able to protect spermatozoa, we tested the hypothesis that cryocapacitation and apoptosis like changes can contribute to the negative effect of freezing and thawing on bull spermatozoa, and that GSH prevent this damage. Having known protective effects of GSH in terms of a potent antioxidant, we evaluated capacitation, tyrosine phosphorylation and apoptosis like changes in bull spermatozoa after freezing and thawing in egg yolk tris glycerol extender containing (0.5m M-GSH-T1 & 1mM GSH-T2) and without GSH serving as the control (C). Forty ejaculates were collected from four Hariana bulls and were pooled due to non significant variations among the bull ejaculates for the evaluation of sperm attributes. Capacitation like changes, tyrosine phosphorylation, localization of tyrosine phosphorylated proteins, apoptosis like changes in terms of mitochondrial transmembrane potential and DNA fragmentation after final dilution, 4h of equilibration at 4°C and 24h after freezing and thawing were evaluated. GSH supplementation at 0.5mM showed significant reduction in B- and AR- pattern spermatozoa during all stages of semen freezing and thawing. Immunoblot revealed six proteins which were tyrosine phosphorylated and protein of 30 and 75kDa (p30, p75) were the major tyrosine phosphorylted proteins. On further analysis, the p30 showed differential variation in intensity in all the three groups after freezing and thawing. Positive immune reactivity for tyrosine phosphorylated proteins was found in neck, middle piece and post-acrosomal regions of spermatozoa. Addition of 0.5mM GSH decreased percentage of spermatozoa showing fragmented DNA and increased the percentage of spermatozoa having high transmembrane mitochondrial potential (P<0.05). This study demonstrates that GSH favours survival of bull spermatozoa by interfering with apoptotic and cryocapacitation pathways, and thereby protects the spermatozoa from deleterious effects of cryopreservation. The findings of the study indicated that GSH at 0.5mM can be effectively used as an additive in bull semen extender for freezing and thawing.

Functional and molecular characterization of voltage gated sodium channel Nav 1.8 in bull spermatozoa.

The aim of our study was to characterize the voltage gated sodium channel Nav 1.8 in bull spermatozoa. Forty ejaculates were collected from four Hariana bulls and semen samples were pooled in view of the nonsignificant variations between different ejaculates. Functional characterization was undertaken using A-803467, a selective blocker of Nav1.8, and veratridine as an opener of the voltage gated sodium channels while molecular characterization was done using western blotting and indirect immunofluorescence assays. In vitro capacitation was induced using heparin, and to study the functional involvement of Nav 1.8 in regulation of capacitation induced hyper sperm motility, A-803467 was used. Selective blocking of NaV 1.8 by A-803467 at 6 and 8 µM concentration significantly (P < 0.05) decreased the forward progressive sperm motility in a time-dependent manner, while, blocking at higher concentrations (10 and 15 µM) resulted in fast forward motility in spermatozoa after 2 h of incubation and it was observed up to 3 h. Treatment of sperm cells with veratridine (6, 8, 10, 15, 20 µM) resulted in concentration- and time-dependent increase in forward progressive sperm motility and it persisted up to 4 h. However, hyperactive motility was induced by veratridine at higher concentrations (10 and 15 µM) after 2 h of incubation. In vitro capacitated spermatozoa treated with A-803467 revealed significant (P < 0.05) reduction in forward progressive motility after 2 h of incubation. Both A-803467 and veratridine altered the percentage of spermatozoa showing high mitochondrial transmembrane potential in concentration- and time-dependent manner. High concentrations (10 and 15 µM) of A-803467 and veratridine resulted in bent neck condition in spermatozoa along with significant (P < 0.05) reduction in membrane integrity (HOST negative). Immunoblot revealed the presence of a single protein band of 260 kDa molecular weight along with positive immunoreactivity (IR) in head, neck, middle piece and tail of the spermatozoa. Strongest IR was observed in the neck and middle piece whereas weak IR was observed in tail and acrosomal region of the spermatozoa. Results of our present study evidently revealed the presence of voltage gated sodium channel Nav1.8 in bull spermatozoa and its functional involvement in regulation of spermatozoa dynamics in terms of motility, membrane integrity, acrosome integrity, capacitation and mitochondrial transmembrane potential. Further studies are warranted to unravel their mechanistic pathways and/or their interaction with other ion channels in regulating sperm dynamics.

Changing Trends of Skin Cancer: A Tertiary Care Hospital Study in Malwa Region of Punjab.

INTRODUCTION: Skin cancer constitutes a small but significant proportion of patients with cancer. Although the presence of eumelanin in dark skin is protective against the development of skin cancer, it is increasingly being diagnosed in the Indian population. AIM: To study the profile of skin cancer patients presenting to a tertiary hospital in Malwa area of Punjab, India. MATERIALS AND METHODS: Retrospective study was done to analyse the profile of skin cancer patients who attended the institution over one year from 1(st) December 2013 to 30(th) November 2014. A comprehensive review of aetiology and related risk factors was done to correlate the environmental factors with high skin cancer prevalence in this region. RESULTS: Skin cancer constituted (3.18%) 84 out of 2638 patients registered with cancer of all types. The age of the patients was 62±14.2 years and ranged from 27 to 92 yrs. Basal cell carcinoma (BCC) was the most common histological type(46/84, 54.76%) followed by squamous cell carcinoma (SCC) (31/84, 36.91%) and malignant melanoma (MM) (7/84, 8.33%). Male: female ratio was found to be 0.79:1. BCC showed higher female preponderance (p<0.05). Head and Neck was the commonest site involved (p<0.05). Majority (88%) of patients were from rural area. 92% of patients were directly into the profession of agriculture with history of prolonged exposure to sunlight. CONCLUSION: Skin cancer constitutes a small but significant proportion of patients with cancers. This study highlights a paradoxically increasing trend of BCC and female preponderance. Head and neck is the most common site involved. Exposure to Ultra Violet B (UVB) radiation and higher levels of arsenic in drinking water has been reported to be associated with skin cancers. Limited studies show that levels of arsenic and pesticides were higher in the samples of drinking water in Malwa area of Punjab. Therefore a multipronged strategy to provide safe drinking water supply and discouraging the indiscriminate use of pesticides is recommended.
