Computerized clinical database development in oncology
Deo SVS
Indian Journal of Palliative Care , 2011,
Abstract: In the era of evidence based medicine documentation of clinical data is extremely important. The field of Health informatics is a discipline at the intersection of information science, computer science and health science. Current health informatics field is mainly catering to the general needs of hospital setups. Development of disease / organ/ specialty based computerized clinical data base is still in its infancy and there is a need for clinicians to actively involve in this field to generate authentic and analyzable clinical data. In this article we present our experience of computerized oncology clinical data base development.

Abstract: In India, the most common cancer among men is cancer of lip-oral and its incidence is further increasing. Nodal metastasis is an important prognostic factor in oral cancer. Previous studies on factors associated with nodal involvement are mainly focused on clinical exploration, and there is very little work in statistical modeling for nodal involvement. Also, the available studies have limited covariates and their varying forms. Further, studies available from India have mainly focused either on occult nodal metastasis only or a specific site of oral or stages. Hence, in order to identify epidemiological determinants of nodal metastasis, objective of this study was to develop a regression model to find out factors associated with nodal involvement and assess its validity. 945 histopathologically proven oral squamous cell carcinoma (OSCC) patients who went under surgery including neck dissection during 1995-2013 at the Department of Surgical Oncology, Dr. BRA-IRCH, AIIMS, New Delhi, India, were included for model building. Another data of 204 patients available during 2014-2015 was used for the temporal validation of the developed model. To assess the factors associated with nodal involvement, stepwise multivariable logistic regression procedure was used and results are presented as odds ratio and corresponding 95% confidence interval (CI). Pain at the time of presentation [1.34 (1.02 to 1.77)], sub mucous fibrosis (SMF) [0.45 (0.21 to 0.95)], palpable neck node [2.38 (1.69 to 3.35)], tongue [1.63 (1.07 to 2.46)] as compared to buccal mucosa and degree of differentiation [1.41 (1.05 to 1.89)] were found to be significantly associated with nodal involvement. Further, diagnostic performance of the developed model was found to be satisfactory on temporal validation. These data suggest that, Pain at time of presentation, presence of clinical neck node, SMF, degree of differentiation and oral site are the most probable factors associated with nodal involvement in OSCC.

Raina V,Kunjahari M,Shukla N,Deo SVS
Indian Journal of Cancer , 2011,
Abstract: Background: Breast cancer is now the most common cancer in many parts of India and the incidence varies from 12 to 31/100000, and is rising. Locally advanced breast cancer (LABC) accounts for 30 - 35% of all cases of breast cancers in India. LABC continues to present a challenge and imposes a major health impact in our country. Materials and Methods: We carried out a analysis of our LABC patients who received neoadjuvant chemotherapy (NACT) at our hospital over a 10-year period, from January 1995 to December 2004. We analyzed the response to NACT, disease-free survival (DFS), and overall survival (OS). Results: Patients with stages IIIA, IIIB, and IIIC were included. LABC comprised of 26.24% (609 patients) of new patients. One hundred and twenty-eight (31.1%) patients received NACT. Median age was 48 years and estrogen receptor was positive in 64%. Chemotherapy protocol was an FEC (5-Fluorouracil, Epirubicin, Cyclophosphamide) regimen in the following doses: Cyclophosphamide 600 mg/m2, 5-FU 600 mg/m2, and Epirubicin 75 mg/m2 given every three weeks, six doses, followed by modified radical mastectomy (MRM) and locoregional radiotherapy. The overall response rate (complete response (CR) + partial response (PR)) was 84.4%, clinical CR (cCR) was 13.3% and pathological CR (pCR) was 7.8%. Median DFS and OS were 33 and 101 months, respectively. The disease-free survival (DFS) and overall survival (OS) at five years were 41 and 58%, respectively. Conclusions: This study analyzes the outcome in patients who received NACT, in the largest number of LABC patients from a single center in India, and our results are comparable to the results reported from other centers.
Role of surgery in breast metastasis from carcinoma of the cervix
Yadav Parveen,Manjunath NML,Deo SVS,Shukla N
Indian Journal of Palliative Care , 2011,
Abstract: Carcinoma of the cervix is the most common malignancy among women in India. Although metastatic disease is common, metastasis to breast is rare. A limited number of case reports are published in the world literature. Most of the previous reports of metastatic cervical carcinoma to breast are either autopsy series or widely disseminated disease where no treatment options were available. A rare case of cervical carcinoma presenting as metastasis in breast is reported here where palliative mastectomy improved the general condition of the patient. A female patient aged 58 years was diagnosed and treated for cervical carcinoma, FIGO stage 2B. Four months after the treatment which included both external beam and intracavitory radiotherapy, the patient presented with breast and lung metastasis. Palliative mastectomy was done which improved the general condition of the patient. Metastatic carcinoma of the cervix can present as a case of breast carcinoma. In an appropriate setting, this possibility should be kept in mind. Palliative mastectomy should be offered for patients of cervical carcinoma with metastasis to breast when needed.
Aggressive palliative surgery in metastatic phyllodes tumor: Impact on quality of life
Kapali A,Singh M,Deo SVS,Shukla N
Indian Journal of Palliative Care , 2010,
Abstract: Metastatic phyllodes tumor has very few treatment options. Phyllodes tumor in metastatic setting has limited role of surgery, radiotherapy and chemotherapy or combined treatment. Most of the patients receive symptomatic management only. We present a case of metastatic phyllodes tumor managed with aggressive margin negative resection of primary tumor leading to palliation of almost all the symptoms, which eventually led to improved quality of life and probably to improved survival. The improved quality of life was objectively assessed with Hamilton depression rating scale. Surgery may be the only mode of palliation in selected patients that provides a better quality of life and directly or indirectly may lead to improved survival.
Fluoroquinolones Reported Hepatotoxicity  [PDF]

Pharmacology & Pharmacy (PP) , 2012, DOI: 10.4236/pp.2012.33044
Abstract: Fluoroquinolones are known to be safe and well tolerated. They are said to have the widest clinical acceptability when compared with other antibiotics. Their reported side effects include gastrointestinal tract, central nervous system effect and blood disorder. Rare side effects include phototoxicity, hypersensitivity, convulsion, psychosis, tendinitis, hypoglycemia, cardiotoxicity and nephrotoxicity. Some of these side effects have led to the withdrawal of some fluoroquinolones like travofloxacin from clinical use in some countries. Of recent fluoroquinolones induce cardiotoxicity and hepatotoxicity has gain attention. Due to increasing reports on fluoroquinolones associated hepatotoxicity in experimental Animal studies and clinical experience. This study reviews reported hepatotoxicity associated with clinically used fluoroquinolones and their safety profile on liver function. It was observed that some fluoroquinolones may have hepatotoxic potential. Reported fluoroquinolones induce hepatotoxicity manifested as hepatitis, pancreatis, jaundice, liver injury and hepatic failure. Most reported cases of fluoroquinolones induced hepatotoxicity were marked by elevated levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, direct bilirubin, total bilirubin and prolong prothrobin time. In some reported cases liver biopsy revealed hepatocellular damage, necrosis and degeneration. Mixed inflammatory infiltrates containing eosinophils, portal edema, bile ductular proliferation and lobular cholestasis were also observed in some cases. The mechanism of fluoroquinolones induce hepatotoxicity may involve generation of oxidative radicals in the liver during drug metabolism which induces DNA damage, mitochondrial damage and gene regulation leading to hepatocellular damage. This was observed in travofloxacin which enhances hepatic mitochondrial peroxynitrite stress in mice with underlying increased basal levels of super oxide leading to the disruption of critical mitochondrial enzyme and gene regulation. This mechanism could be associated with fluoroquinolones mechanism of action which includes DNA damage. In conclusion fluoroquinolones are well tolerated but some may have hepatotoxic potential. Most clinically used fluoroquinolones are relatively safe but Clinicians should consider patients liver function status before fluoroquinolones clinical recommendation. In some cases biochemical parameters associated with liver function should be monitored in patients with impaired liver function.
Hepatoprotective Effect of Vitamin C (Ascorbic Acid)  [PDF]
Elias Adikwu, Oputiri Deo
Pharmacology & Pharmacy (PP) , 2013, DOI: 10.4236/pp.2013.41012
Abstract: Human and animal studies have shown that some drugs and chemical agents have potential hepatotoxic effects. The hepatotoxic effect of drugs and some chemical agents is reported to be associated with the generation of reactive oxygen species (ROS). These ROS are reported to be associated with lipid peroxidation in the liver. This mechanism has led to continuous evaluation of the hepatoprotective effect of antioxidants in humans and animals. Among the antioxidants been evaluated is vitamin C which is a water soluble antioxidant. Reports have linked vitamin C with hepatoprotective property in animals and humans. It synergistic hepatoprotective effect with other antioxidants was also reported. Due to these reports a comprehensive literature review on the hepatoprotective property of vitamin C in humans and animals was performed. It was observed that vitamin C exhibited a reputable hepatoprotective effect in humans and animals. Research showed that vitamin C inhibited hepatotoxicity induced by drugs, heavy metals, organophosphate insecticides and some chemical agents. Vitamin C was reported to normalized levels of serum alanine aminotransferase, aspartate aminotransferase, gamma glutamine, alkaline phosphatase, lactate dehydrogenase and malondialdehyde and serum bilirubin in intoxicated animals. It potentiates the activities of free radical scavengers, superoxide dimutase, and catalase glutathione peroxidase thereby preventing microsomal lipid peroxidation, liver fibrosis, liver necrosis and hepatic inflammation. In humans vitamin C was reported to be beneficial in non alcoholic steatohepatitis and in patients with fatty liver disease. Hepatoprotective property of vitamin C is attributed to it antioxidant property. Vitamin C (ascorbic acid) which is a major water-soluble antioxidant is believed to decrease lipid peroxidation either directly or indirectly by regenerating vitamin E. Vitamin C is an important free radical scavenger in extracellular fluids, trapping radicals and protecting biomembranes from peroxide damage. Vitamin C effectively scavenges singlet oxygen, superoxide, hydroxyl, water soluble peroxyl radical and hypochlorous acid. It is also reported to be an excellent source of electrons and therefore can donate electrons to free radicals such as hydroxyl and super oxide radicals and quench their activity. Vitamin C is an essential co-factor involved in many biochemical functions and acts as an electron donor or reducing agent. In this review it is observe that vitamin C has hepatoprotective effect which increases
