RESUMEN
Breast cancer is a public health challenge globally as well as in India. Improving outcome and cure requires appropriate biomarker testing to assign risk and plan treatment. Because it is documented that significant ethnic and geographical variations in biological and genetic features exist worldwide, such biomarkers need to be validated and approved by authorities in the region where these are intended to be used. The use of western guidelines, appropriate for the Caucasian population, can lead to inappropriate overtreatment or undertreatment in Asia and India. A virtual meeting of domain experts discussed the published literature, real-world practical experience, and results of opinion poll involving 185 oncologists treating breast cancer across 58 cities of India. They arrived at a practical consensus recommendation statement to guide community oncologists in the management of hormone positive (HR-positive) Her2-negative early breast cancer (EBC). India has a majority (about 50%) of breast cancer patients who are diagnosed in the premenopausal stage (less than 50 years of age). The only currently available predictive test for HR-positive Her2-negative EBC that has been validated in Indian patients is CanAssist Breast. If this test gives a score indicative of low risk (< 15.5), adjuvant chemotherapy will not increase the chance of metastasis-free survival and should not be given. This is applicable even during the ongoing COVID-19 pandemic.
RESUMEN
Ninety-eight single lumen and two double lumen silicone right atrial Hickman/Broviac catheters inserted in 91 patients with various malignancies over a period of 36 months were prospectively studied. The average duration of use for all Hickman/Broviac catheters was 7,460 days with an average of 74.6 days. A total of 41 episodes of catheter-related infections were documented in all patients (0.5 per 100 access days). Catheter related bacteremia was the most frequent type of infection (31 out of 41, 75%). Majority of the bacteremias could be controlled with routine antimicrobial therapy. Exit site infections were seen in 5 Hickman/Broviac catheters. Two catheters had to be removed because of catheter tunnel infections. Gram negative bacteremic infections were the most common, with Pseudomonas aeruginosa being the major pathogen. Silicone rubber Hickman/Broviac catheters proved to be convenient, reliable, and easily manageable devices in our experience.

We report a case of primary extragonadal germ cell tumor of the penis in a 2-year-old child with elevated serum alpha-fetoprotein. The patient responded well to a combination of bleomycin, etoposide and cisplatin, achieving a complete response within 3 cycles. He was alive and disease-free 8 months after diagnosis. To our knowledge this is the first case of an endodermal sinus tumor of the penis reported in the literature. The possible histogenesis of this tumor at such a rare site is discussed.

A 37 year old man with symptomatic multiple myeloma diagnosed in April 1968 presented with generalised bony pains, extensive skeletal osteolytic lesions, monoclonal gammopathy and 90 percent atypical plasma cells in the marrow. He was given cyclophosphamide for six months with minimal response and then initiated on melphalan for one year. He was asymptomatic for 15 years thereafter and presented again in 1985 with a relapse of the disease. Over the next four years he was given various combinations of chemotherapy including cyclophosphamide, vincristine, melphalan and carmustine. He responded well on two more occasions only to relapse again. Recently, he has developed a symptomatic relapse with 36 percent plasma cells. This case report highlights the fact that there is a subset of patients with myeloma who survive beyond ten years, but remain symptomatic and respond slowly to chemotherapy.

Seven of 368 cases of acute myeloid leukemia (AML) could not be subclassified by routine morphologic, cytochemical and immunologic analyses during the period January 1989 to December 1990. Further investigations including ultrastructural examination, anti-myeloperoxidase and myeloid specific antigen analysis were carried out in all these patients and they were classified as AML-MO, as per the FAB criteria. Morphologically these blasts resembled ALL-L2/AML-M1. Cytochemically they were negative for Sudan black, myeloperoxidase, periodic acid-Schiff, and non-specific esterase. On initial immunophenotypic analysis, they could not be classified into B, T or myeloid lineages. Further investigations revealed CD13 and CD33 positivity in 4 of 6 patients. Anti-myeloperoxidase was positive in 6 of 6 patients and ultrastructural examination revealed myeloperoxidase-positive blasts in 6 of 7 cases. Cytogenetic analysis done in one patient revealed 60% abnormal metaphases. Six of 7 cases were treated with aggressive chemotherapy. One patient achieved complete remission but relapsed after 6 months, whereas others were resistant to treatment. Hence we conclude that an aggressive investigative and therapeutic approach is required to identify and treat AML-MO.

Primary non-Hodgkin's lymphoma of the liver is exceedingly rare and until now only 53 cases have been recorded. Most extranodal non-Hodgkin's lymphomas are in the head and neck region and the gastrointestinal tract. We report a patient with primary non-Hodgkin's lymphoma of the liver and also review the relevant literature.
