Background:
Limited guidelines exist for breast cancer management in developing countries. In this context, the Women's Cancer Initiative - Tata Memorial Hospital (WCI-TMH) organised its 8
th
Annual Conference to update guidelines in breast cancer.
Materials and Methods:
Appropriately formulated guideline questions on each topic and subtopic in the surgical, radiation and systemic management of primary breast cancer were developed by the scientific committee and shared with the guest faculty of the Conference. Majority of the questions had multiple choice answers. The opinion of the audience, comprising academic and community oncologists, was electronically cumulated, followed by focussed presentations by eminent national and international experts on each topic. The guidelines were finally developed through an expert panel that voted on each guideline question after all talks had been delivered and audience opinion elicited. Separate panels were constituted for locoregional and systemic therapy in primary breast cancer.
Results:
Based on the voting results of the expert panel, guidelines for locoregional therapy of breast cancer have been formulated. Voting patterns for each question are reported.
Conclusions:
The updated guidelines on locoregional management of primary breast cancer in the context of developing countries are presented in this article. These recommendations have been designed to allow centers in the developing world to improve the quality of care for breast cancer patients.

Cytokeratin 19 immunoreactivity in the diagnosis of papillary thyroid carcinoma
Debdas Bose, Ram Narayan Das, Uttara Chatterjee, Uma Banerjee
April-June 2012, 33(2):107-111
DOI
:10.4103/0971-5851.99746
PMID
:22988353
Context:
The diagnosis of papillary thyroid carcinoma (PTC) is based on nuclear features. These features may be present in focal areas in benign thyroid diseases and follicular adenoma (FA), leading to diagnostic difficulty.
Aims:
To evaluate the expression and pattern of the distribution of cytokeratin 19 (CK19) in PTC and compare its reactivity with other neoplastic and non-neoplastic conditions to assess its potential as a useful marker for PTC.
Materials and Methods:
Twenty two cases of papillary carcinoma (usual type, follicular and diffuse sclerosing variant), eight follicular adenomas, eight multinodular goiters (MNG) were collected for a period of two years and six months. Sections were taken from thyroidectomy specimens fixed in 10% buffered neutral formalin. Hematoxylin and eosin staining and immunohistochemical staining for CK19 were done using standard protocol. Results were semiquantitatively scored as follows: 1+ (<5% positively stained cells), 2+ (5-25%), 3+ (25-75%) and 4+ (>75%), and then analyzed.
Statistical Analysis and Results:
All 22 (100%) papillary carcinomas showed diffuse and strong (3+ and 4+) CK19 expression. Six out of eight (75%) FAs and four out of eight (50%) MNG were positive for CK19, but it was of weaker intensity (1+ and 2+) and focal in distribution.
Conclusion:
Focal CK19 staining may be found in benign disease, but diffuse and strong positivity is characteristic of PTC, which can be used in the diagnosis of PTC in lesions of equivocal morphological appearances.

Current therapy and recent advances in the management of retinoblastoma
Rachna Meel, Venkatraman Radhakrishnan, Sameer Bakhshi

Retinoblastoma is the most common intraocular malignancy in children. The survival of retinoblastoma patients and visual outcome has improved dramatically in the developed world. This can be attributed to early tumor recognition and advances in the management of retinoblastoma. Chemoreduction followed by adjuvant consolidative treatment has replaced external beam radiotherapy as the primary modality of treatment for intraocular retinoblastoma. Further, histopathological high-risk factors have been identified in enucleated eyes, allowing use of prophylactic chemotherapy to take care of possible micrometastasis. The survival in case of extraocular retinoblastoma is still low, and the reported survival rate ranges between 50% and 70%. In developing countries, the overall survival of retinoblastoma patients remains low, primarily due to a delayed presentation, resulting in larger proportions of extraocular disease compared with the developed world, where majority of the disease is intraocular. Greater efforts need to be directed toward early tumor recognition in order to improve the survival of retinoblastoma patients in the developing world. In this article, we provide an overview of the current clinical management of retinoblastoma.

Xeroderma pigmentosum (XP) is a rare autosomal recessive genodermatosis associated with hypersensitivity to ultraviolet light due to defects in Deoxyribonucleic acid (DNA) repair. These patients have more than a 1000-fold increased risk of developing skin cancers. Although multiple cutaneous malignancies are common, the simultaneous occurrence of angiosarcoma and basal cell carcinoma is a rare phenomenon. We report a case of a 25-year-old male with XP with angiosarcoma scalp and basal cell carcinoma of face and occiput and discuss the treatment of this aggressive neoplasm with a review of the literature pertaining to it.

Arecanut as an emerging etiology of oral cancers in India
Gunjan Shah, Pankaj Chaturvedi, Sagar Vaishampayan
April-June 2012, 33(2):71-79

Arecanut (AN) usage is widespread in Asian countries, especially India and Taiwan. The incidence of oral cancer is increasing day by day, but there is no exponential increase with tobacco usage. Especially in the country like Taiwan where betel quid mostly do not contain tobacco, AN can be correlated with the increased incidence of cancer. There are different studies in the literature about AN and oral cancer but none of them have concluded with the definite pathway for carcinogenesis. The present paper includes reviews of the literature for AN and oral cancer and summarizes the possible mechanisms associated with AN-induced carcinogenesis; and we have also tried to propose pathway of carcinogenesis.

Primitive neuroectodermal tumor (PNET) of kidney is a rare tumor of kidney with only a few published reports. We report here four cases of PNET of kidney in the age group between 30 and 50 years who had complaints of vague pain and lump in loin. Hematuria was present in one case. Imaging of all cases revealed renal mass. The pathologic findings were consistent with PNET in all cases-confirmed by immunohistochemistry with diffuse membrane positivity of tumor cells of CD99. We could not do fluorescent
in situ
hybridization to demonstrate EWS-FLI-1 gene fusion. Each case was in the advanced stage. However, after giving postoperative radiotherapy and chemotherapy patients are still alive. Reporting of these cases are important as we got them in a short span of 3 years. In view of its poor prognosis, aggressive nature and different therapeutic approach- renal PNET should be differentiated from other small blue round cell tumors like neuroblastoma, rhabdoid tumor of kidney, nephroblastoma, small cell carcinoma, synovial sarcoma (monophasic, poorly differentiated) and non-Hodgkin lymphoma (NHL) by immunohistochemistry, cytogenetic, and molecular genetics study to see the different gene rearrangements in NHL and 3p deletion in small cell carcinoma.

Benign mediastinal teratomas are commonly asymptomatic and seldom cause complications. Spontaneous rupture into the pleura is rare and cross-sectional imaging is crucial in its early detection and planning a proper surgical approach. We report two cases of spontaneous pulmonary and pleural rupture of benign mediastinal teratoma and discuss the imaging appearances.

Study of histopathological features and proliferation markers in cases of Wilms' tumor
Ram Narayan Das, Uttara Chatterjee, Swapan K Sinha, Ashoke K Ray, Koushik Saha, Sugato Banerjee
April-June 2012, 33(2):102-106
DOI
:10.4103/0971-5851.99744
PMID
:22988352
Context:
The spectrum of pediatric renal tumors is different from adult renal tumors, and Wilms' tumor (WT) forms the majority. The histological type and clinicopathological staging are the two important prognostic parameters. The role of newer prognostic factors is not clear.
Aims:
This study was performed to analyze the histopathological spectrum of pediatric renal tumors and to study the expression of proliferation markers (Ki-67 and p53) in WT and correlate its expression in epithelial and blastema components in different stages.
Materials and Methods:
Twenty-seven cases of pediatric renal tumors were collected over 2 years. Hematoxylin-eosin staining was used for diagnosis. Immunostaining was performed for Ki-67 and p53. Ki-67 proliferation index (PI) and p53 expression were determined in each case and for the epithelial and blastema components separately.
Statistical Analysis and Results:
We had 20 cases of WT (74.1%), three cases of mesoblastic nephroma (11.1%), three cases of clear cell sarcoma (11.1%) and one case of rhabdoid tumor (3.7%). It was observed that the PI of the epithelial component (57.2%) was significantly higher than that of blastema (39.53%) in all stages. The PI in Stage II is significantly higher than that in Stage I. Statistical analysis could not be performed in Stages III and IV due to the small number of cases. p53 expression did not show any significant difference in the epithelial and blastema components. There was also no significant difference between the stages.
Conclusion:
In this study, we found the differences between PI of different tissue components of WT, with the epithelial component having a higher PI, which correlated with the stage of advancement of the disease.

Diarrhea in neutropenic children with cancer: An Egyptian center experience, with emphasis on neutropenic enterocolitis
Laila M Sherief, Mohamed R Beshir, Naglaa Mohamed Kamal, Maha K Gohar, Ghada K Gohar
April-June 2012, 33(2):95-101
DOI
:10.4103/0971-5851.99742
PMID
:22988351
Background:
Diarrhea is a frequent complication in children with cancer who received intensive chemotheraputic regimens. It may be caused by several factors, neutropenic enterocolitis (NE) being the most serious.
Aim:
To study diarrhea in neutropenic cancer patients in the pediatric age group, with its underlying etiologies and risk factors, especially the bacterial causes, with special concern on NE.
Materials and Methods:
This study was carried out at the Pediatric Hematology and Oncology Units, Zagazig University Hospitals, Egypt, from January 2009 to September 2010. All children with malignant diseases who are ≤12 years of age were included. Patients who were neutropenic (<500/ mm
3
) on admission or who became neutropenic during their stay in the hospital were monitored regularly (daily) for diarrhea. Neutropenic cancer patients with diarrhea were grouped into two groups: Group 1, with NE, and group 2, with neutropenic diarrhea rather than NE. On the first day of diarrhea, patients were subjected to complete blood count, blood cultures, stool microscopy and culture. Abdominal ultrasonography was carried out within 3 days of diarrhea.
Results:
A total of 200 children ≤12 years old, suffering from different malignancies, with a total of 180 neutropenic episodes were followed. Diarrhea was observed in 100 episodes (55.5%). NE constituted 16% of these diarrheal episodes. All patients with NE had significantly more severe neutropenia, and this was of longer duration than the other group. All patients with NE were febrile, with 100% positive blood culture. Stool analysis diagnosed giardiasis in 4.8% of the non-NE patients and in none of the NE patients, while stool culture was positive in 75% of the NE patients compared with 40.5% of the other group.
Conclusions:
Diarrhea is a common complication in neutropenic cancer children. Gram negative bacteria and Candida are the most incriminated pathogens. Duration and severity of neutropenia carry a great risk for the development of NE.
