Neoadjuvant chemotherapy followed by surgical cytoreduction in advanced epithelial ovarian cancer
AIMS: To study the role of neoadjuvant chemotherapy (NACT) followed by
surgical cytoreduction in the management of advanced epithelial ovarian
cancers. MATERIALS AND METHODS: A retrospective analysis of 82
patients with advanced epithelial ovarian cancers (stage IIIC and IV)
who were treated with NACT followed by surgical cytoreduction between
1995 and 2004 was performed. Response to NACT, optimal cytoreduction
rate, disease-free survival and overall survival were analyzed.
RESULTS: There were 59 patients (72%) with stage IIIC disease and 23
(28%) with stage IV disease. Diagnosis was established by imaging,
ascitic fluid cytology and CA-125 estimations in 75% and by laparotomy
in 25% of the patients. After NACT, complete response occurred in 17
patients (20.7%), 50 (61.0%) had partial response and no response was
documented in 15 (18.3%) patients. Optimal surgical cytoreduction could
be achieved in 72% of the patients. At the median follow-up of 34
months (range 6-102 months), 5-year disease-free and overall survivals
were 31 and 32% respectively. The median disease free interval was 25.4
months. On multivariate analysis, degree of optimal cytoreduction was
the only factor ( P < 0.05) affecting survival. CONCLUSIONS: NACT
followed by surgical cytoreduction is a promising treatment strategy
for the management of advanced epithelial ovarian cancers. A
significant number of patients exhibit response to NACT. Downstaging
following NACT leads to higher optimal cytoreduction rates and improved
survival in comparison to historical controls

Association of mutation and expression of the brother of the regulator of imprinted sites (BORIS) gene with breast cancer progression
INTRODUCTION: The BORIS, 11 zinc-finger transcription factors, is a member of the cancer-testis antigen (CTA) family. It is mapped to chromosome number 20q13.2 and this region is genetically linked to the early onset of breast cancer. The current study analyzed the correlation between BORIS mutations and the expression of the protein in breast cancer cases.
MATERIALS AND METHODS: A population-based study including a total of 155 breast cancer tissue samples and an equal number of normal adjacent tissues from Indian female breast cancer patients was carried out. Mutations of the BORIS gene were detected by polymerase chain reaction-single standard confirmation polymorphisms (PCR-SSCP) and automated DNA sequencing and by immunohistochemistry for BORIS protein expression were performed. The observed findings were correlated with several clinicopathological parameters to find out the clinical relevance of associations.
RESULTS: Of all the cases 16.12% (25/155) showed mutations in the BORIS gene. The observed mutations present on codon 329 are missense, leading to Val\u3e Ile (G\u3eA) change on exon 5 of the BORIS gene. A significant association was observed between mutations of the BORIS gene and some clinicopathological features like nodal status (p = 0.013), estrogen receptor (ER) expression (p = 0.008), progesterone receptor (PR) expression (p = 0.039), clinical stage (p = 0.010) and menopausal status (p = 0.023). The protein expression analysis showed 20.64% (32/155) samples showing low or no expression (+), 34.19% (53/155) with moderate expression (++), and 45.17% (70/155) showing high expression (+++) of BORIS protein. A significant association was observed between the expression of BORIS protein and clinicopathological features like clinical stage (p = 0.013), nodal status (p = 0.049), ER expression (p = 0.039), and PR expression (p = 0.027). When mutation and protein expression were correlated in combination with clinicopathological parameters a significant association was observed in the category of high (+++) level of BORIS protein expression (p = 0.017).
CONCLUSION: The BORIS mutations and high protein expression occur frequently in carcinoma of the breast suggesting their association with the onset and progression of breast carcinoma. Further, the BORIS has the potential to be used as a biomarker
Computerized Clinical Database Development in Oncology
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
Brief Report - An Analysis of Long-term Venous Access Catheters in Cancer Patients: Experience from a Tertiary Care Centre in India
Background: Venous access is crucial for administration of drugs blood
products, antibiotics and periodic sampling in patients with cancer.
Aims: To review our experience of longterm venous access devices used
over a ten year period and to analyse the outcome in cancer patients in
Indian setting. Setting and Design: A retrospective analysis of data in
a tertiary care Regional cancer center. Patients and Methods: A total
of 110 patients with various malignancies requiring longterm venous
access were included in the study. A uniform open cut down procedure
under local anaesthesia was used and silastic hickman catheters were
inserted in the cephalic or external jugular or internal jugular veins.
A record of all complications and catheter loss and final out come were
analysed. Results: A total of 111 catheters were used in 110 patients.
Sixty nine catheters were placed in cephalic, 40 in external jugular,
and 2 in internal jugular vein. Duration of catheter indwelling period
ranged from 7 to 365 days with a median of 120 days. In 90% of the
cases the catheter tip was located either in superior vena cava or in
right atrium. Total catheter related complications were observed in 37
(34.54%) patients and catheter loss rate due to complications was 15.4%
(17/111). Conclusions: Long term venous access using Hickman catheter
insertion by open cut down method is a simple, safe and reliable method
for administration of chemotherapeutic agents, antibiotics and blood
products. The incidence of various complications and catheter loss was
acceptable and overall patient satisfaction was good
An update in the management of malignant pleural effusion
Malignant pleural effusion (MPE) usually presents in the disseminated and advanced stage of malignancy. Dyspnea is the debilitating symptom which needs palliation in these patients. Various modalities are available in the management of MPE. Careful consideration of the patient′s expected survival and quality of life is needed when deciding the optimum treatment modality in such patients. In this article, different modalities of the palliative management of MPE are discussed with an attempt to derive a treatment algorithm for the management of MPE
Association of Overweight and Obesity with Breast Cancer in India
Background : In women, cancer of the breast is one of the most common incident cancer and cause of death from cancer. Anthropometric factors of weight, height, and body mass index (BMI) have been associated with breast cancer risk. Objectives : To study the association of overweight and obesity with breast cancer in India. Materials and Methods: A hospital-based matched case-control study was conducted. Three hundred and twenty newly diagnosed breast cancer patients and three hundred and twenty normal healthy individuals constituted the study population. The subjects in the control group were matched individually with the patients for their age ±2 years and socioeconomic status. Anthropometric measurements of weight and height were recorded utilizing the standard equipments and methodology. The paired ′t′ test and univariate logistic regression analysis were carried out. Results: It was observed that the patients had a statistically higher mean weight, body mass index, and mid upper arm circumference as compared to the controls. It was observed that the risk of breast cancer increased with increasing levels of BMI. Overweight and obese women had Odd′s redio of 1.06 and 2.27, respectively, as compared to women with normal weight. Conclusions: The results of the present study revealed a strong association of overweight and obesity with breast cancer in the Indian population
