    Imatinib is an FDA approved first-line treatment for Philadelphia-positive CML. It is a selective tyrosine kinase inhibitor specifically targeting BCR-ABL, c-KIT, PDGFRA. It has been reported with low incidence of adverse effects and high tolerability, with haemorrhagic events being a rare complication. We report here a case of 51-year-old female patient with chronic myeloid leukemia who was on high dose imatinib experienced recurrent sub-dural haemorrhage. This case report emphasizes on the need to consider Sub dural haemorrhage as an unusual cause of headache associated with vomiting in a patient taking high dose of imatinib

    Pertuzumab: Unprecedented benefit in human epidermal growth factor receptor 2-positive breast cancer

    Human epidermal growth factor receptor 2 (HER2)-positive breast cancer is a more aggressive subtype of breast cancer and targeting the HER2 receptor has proven effective in improving the prognosis of these patients. Pertuzumab, a recombinant humanized monoclonal antibody and the first in a class of HER2 dimerization inhibitors approved for treating HER2+ breast cancer. It blocks ligand-dependent heterodimerization and ligand-independent homodimerization of HER2 with other HER members. When used in combination with trastuzumab and taxane, pertuzumab complements the action of trastuzumab and results in a comprehensive blockade of HER2 signaling pathway. This review article traces the development of pertuzumab from concept to its current use in HER2+ breast cancer treatment. A search of Medical Literature Published since 2007 was performed in PubMed using the keywords “pertuzumab,” “HER2+ breast cancer,” “HER2 targeted therapy,” “metastatic breast cancer,” and in search engines for ongoing trials with pertuzumab and incidence of cancer and breast cancer in India. A total of 35 publications and abstracts from the American Society of Clinical Oncology were selected for this review. Pertuzumab is approved in combination with trastuzumab and docetaxel for the treatment of patients with HER2+ metastatic BC, who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. The dual HER2 blockade of pertuzumab and trastuzumab is now accepted worldwide as a standard of care by various guidelines

    ExPert ConsEnsus on the management of Advanced clear-cell RenaL celL carcinoma: INDIAn Perspective (PEARL-INDIA)

    No full text
    Abstract In advanced Renal Cell Carcinoma (aRCC), systemic therapy is the mainstay of treatment, with no or little role for surgery in these patients. Tyrosine kinase inhibitors (TKIs) and immune-oncological (IOs) therapies, either alone or in combination, are recommended in these patients depending on patient and tumour factors. The sequencing of therapies is critical in RCC because the choice of subsequent line therapy is heavily dependent on the response and duration of the previous treatment. There are additional barriers to RCC treatment in India. Immunotherapy is the cornerstone of treatment in ccRCC, but it is prohibitively expensive and not always reimbursed, effectively putting it out of reach for the vast majority of eligible patients in India. Furthermore, in advanced RCC (particularly the clear cell variety), Indian oncologists consider the disease burden of the patients, which is particularly dependent on the quantum of the disease load, clinical symptoms, and performance status of the patient, before deciding on treatment. There are no India-specific guidelines for clear cell RCC (ccRCC) treatment or the positioning and sequencing of molecules in the management of advanced ccRCC that take these country-specific issues into account. The current consensus article provides expert recommendations and treatment algorithms based on existing clinical evidence, which will be useful to specialists managing advanced ccRCC

    Patterns of epidermal growth factor receptor testing across 111 tertiary care centers in India: Result of a questionnaire-based survey

    Background: We conducted a survey of 111 medical oncologists across India to understand the current pattern of epidermal growth factor receptor (EGFR) mutation testing at their respective centers. Methods: Medical oncologists from 111 institutes across India were interviewed face to face using a structured questionnaire. They were divided into two groups – Group 1 with in-house EGFR testing and Group 2 who send samples to central/commercial laboratories outside their institutions. Answers of the two groups were analyzed to see the prevailing patterns of EGFR testing and differences between the two groups if any. Results: Ninety-five percent (105/111) of medical oncologists recommended testing for EGFR mutations in patients with adenocarcinoma histology and 40% (44/111) recommended EGFR testing in squamous cell histology. The average time duration to get EGFR test results was 10 days in Group 1 centers versus 18 days in Group 2 centers. Ninety-six percent (106/111) of the medical oncologists from Group 1 centers requested for factoring additional sample for biomarker testing compared to 69% (77/111) of the oncologists from Group 2 centers. Sixty-nine percent (77/111) of medical oncologists in Group 1 centers would prefer to wait for the test results before initiating treatment compared to 46% (51/111) in Group 2. EGFR tyrosine-kinase inhibitors were used in only approximately 60% of patients with diagnosed EGFR mutation in the first line. For patients in whom chemotherapy was initiated while waiting for test results, 50% (56/111) of medical oncologists would prefer to complete 4–6 cycles before switching to targeted therapy. At the time of progression, rebiopsy was possible in approximately 25% of the patients. Conclusions: Turnaround time for molecular testing should improve so that eligible patients can benefit from targeted therapies in the first line. There is a need to increase the awareness among pulmonologists, oncologists, and interventional radiologists regarding the importance of adequate samples required for molecular tests
