RESUMO

PURPOSE: Accurate understanding of the genomic and transcriptomic data provided by next-generation sequencing (NGS) is essential for the effective utilization of precision oncology. Molecular tumor boards (MTBs) aim to translate the complex data in NGS reports into effective clinical interventions. Often, MTB treatment recommendations differ from those in the NGS reports. In this study, we analyze the discordance between these recommendations and the rationales behind the discordances, in a non-high-income setting, with international input to evaluate the necessity of MTB in clinical practice. METHODS: We collated data from MTB that were virtually hosted in Chennai, India. We included patients with malignancies who had NGS reports on solid tissue or liquid biopsies, and excluded those with incomplete data. MTB forms and NGS reports of each clinical case were analyzed and evaluated for recommendation concordance. Concordance was defined as an agreement between the first recommendation in the MTB forms and the therapeutic recommendations suggested in the NGS report. Discordance was the absence of the said agreement. The rationales for discordance were identified and documented. RESULTS: Seventy MTB reports were analyzed with 49 cases meeting the inclusion criteria. The recommendation discordance was 49% (24 of 49). Discordant recommendations were mainly due to low level of evidence for the drug (75% of cases). CONCLUSION: The discordance between MTB and NGS vendor recommendations highlights the clinical utility of MTB. The educational experiences provided by this initiative are an example of how virtual academic collaborations can enhance patient care and provider education across geographic borders.

RESUMO

ABSTRACT: Chronic myeloid leukemia (CML) is a clonal myeloproliferative neoplasm that is genetically characterized by the presence of the Philadelphia (Ph) chromosome. Variant Ph translocation has been observed in 5% to 10% of the CML cases. In the previous studies, many different types of variant Ph translocations have been observed involving chromosomes 1p36, 3p21, 5q13, 6p21, 9q22, 11q13, 12p13, 17p13, and 10p15. According to the published literature, only two cases with the complex translocations involving long arm of chromosome 16 at band q24 have been reported. We report two female patients with complex translocation (three-way) involving chromosomes 9, 22, and 16 at breakpoint q24 and both patients responded well to Imatinib. The present study included 469 patients of clinically diagnosed CML patients who were referred for cytogenetic analysis to our laboratory. Cytogenetic analysis was performed by GTG banding, and the karyotype was designated according to the International System for Human Cytogenetic Nomenclature. Fluorescence in situ hybridization (FISH) analysis was performed for complex and variant BCR-ABL cases. Of total 469 cases, 248 patients showed classical Ph chromosome [t(9;22)(q34;q11.2)], 198 cases were normal, and 23 patients had variant and complex Ph chromosome translocation. Two patients showed three-way translocation involving long arm of chromosomes 9, 22, and 16 at band 9q34, 22q11.2, and 16q24. In this report, patients with variant Ph translocation did not have a significantly different outcome as compared to the classical translocation. Both cases responded well to Imatinib.

RESUMO

Cancer is a major cause of disease and death across the world, including South Asia. Much of the cancer burden is due to modifiable behavioural/lifestyle related factors (the modifiable 'exposome'), such as the five S's: smoking, spirit (alcohol), stoutness (obesity), unsafe sex, and sugar (hyperglycaemia). The primary diabetes care professional works not only to manage disease, but also to encourage healthy behaviours and promote health. This communication highlights how the diabetes care professional can play a significant part in preventing cancer and reducing the burden of disease.

RESUMO

Background & objectives: High mortality has been observed in the cancer population affected with COVID-19 during this pandemic. We undertook this study to determine the characteristics and outcomes of cancer patients with COVID-19 and assessed the factors predicting outcome. Methods: Patients of all age groups with a proven history of malignancy and a recent diagnosis of SARS-CoV-2 infection based on nasal/nasopharyngeal reverse transcriptase (RT)-PCR tests were included. Demographic, clinical and laboratory variables were compared between survivors and non-survivors groups, with respect to observed mortality. Results: Between May 11 and August 10, 2020, 134 patients were included from the three centres and observed mortality was 17.1 per cent. The median age was 53 yr (interquartile range 39-61 yr) and thirty four patients (25%) were asymptomatic. Solid tumours accounted for 69.1 per cent and breast cancer was the most common tumour type (20%). One hundred and five patients (70.5%) had received chemotherapy within the past four weeks and 25 patients (19.3%) had neutropenia at presentation. On multivariate analysis, age [odds ratio (OR) 7.99 (95% confidence interval [CI] 1.18-54.00); P=0.033], haemoglobin [OR 6.28 (95% CI 1.07-37.04); P=0.042] neutrophil-lymphocyte ratio [OR 12.02 (95% CI 2.08-69.51); P=0.005] and baseline serum albumin [OR 18.52 (95% CI 2.80-122.27); P=0.002], were associated with higher mortality. Recent chemotherapy, haematological tumours type and baseline neutropenia did not affect the outcome. Interpretation & conclusions: Higher mortality in moderate and severe infections was associated with baseline organ dysfunction and elderly age. Significant proportion of patients were asymptomatic and might remain undetected.

RESUMO

Amol PatelBackground In India, breast cancer patients' post-treatment follow-up practices are not known. We did this survey to understand how the breast cancer patients are followed-up and tried to explore the challenges associated with it. Methods We conducted a survey-based study among Indian oncologists. Seven questions were framed pertaining to follow-up practices. Answers were provided in the form of multiple options. Google forms platform was used. Survey was circulated through social media apps and through mail. We sought suggestions and opinions to address the challenges from participants. Results A total of 158 medical oncologists responded to this survey. 10% were not aware that only history and clinical examination are the scientific recommendations for follow-up. Ninety percent of the medical oncologists felt clinical breast examination as an uncomfortable practice for patients and physicians and 39% ordered a chest X-ray and an ultrasound abdomen. Annual mammogram was ordered by 83%, and blood investigations were recommended by 14% routinely. The majority (49.6%) felt that the absence of a female attendant, physician and patient factors were responsible for nonadherence to clinical breast examination. The DEXA scan was recommended by 84 (53%) medical oncologists regularly for patients on aromatase inhibitors, while 23 (14%) did not recommend it. Conclusion There is a disparity between scientific recommendations and real-world follow-up practices. A large number of medical oncologists relied on chest X-ray and ultrasound abdomen. There is an unmet need to address this issue.

RESUMO

There has been a paradigm shift in the management of cancer, with the immense progress in cancer genomics. More and more targeted therapies are becoming available by the day and personalized medicine is becoming popular with specific drugs being designed for selected subgroups of patients. One such new class of targeted drugs in the armamentarium is Poly ADP Ribose Polymerase (PARP) inhibitors (PARPi), which inhibit the enzyme PARP, thus interfering with DNA repair. This strategy utilizes a pre-existing genomic lesion in tumors with homologous recombination repair defects (including BRCA mutations), weakening tumor cells further by blocking the alternate pathway of DNA repair. In this review, we discuss in detail, the evolution, genetics, mechanism of action, mechanism of resistance, indications of use of PARP inhibitors, as well as combination with other agents and future directions.

RESUMO

Clinico-pathological differences between adenocarcinoma in the right and left colo-rectum play a role in determining the prognosis and response to treatment. Studies suggest that primary tumor location is more relevant as the disease progresses and reflects a possible difference in biology and response to therapy. This review aims to explore the clinico-pathological features of right and left colo-rectum and the impact of primary tumor location on prognosis of CRC as well as discuss the available clinical data on tumor sidedness in metastatic colorectal cancer. In so far as the clinical data of tumor sidedness is concerned, very few reviews have discussed the clinical implications of sidedness in heavily pre-treated metastatic colorectal cancer (second and subsequent lines of therapy in metastatic disease). This review aims to fill the current gap in this setting.

RESUMO

PURPOSE: It is projected that approximately 50,000 new cases of prostate cancer will be diagnosed in 2020 in India. Survival has improved because of the development of effective drugs such as abiraterone acetate, but universal accessibility to treatment is not always possible because of cost constraints in lower- and middle-income countries. Recently, the National Comprehensive Cancer Network (NCCN) has included low-dose abiraterone (250 mg/day) with food as an alternative treatment option to full-dose abiraterone (1,000 mg/day) fasting. METHODS: The Science and Cost Cancer Consortium conducted a survey to evaluate the use of abiraterone in India and the opinions of medical oncologists about using low-dose treatment. Modeling was used to estimate potential financial benefits to individual patients and to estimate overall costs of health care in India if low-dose abiraterone is prescribed. RESULTS: Of 251 Indian medical oncologists who were invited to participate in the survey, 125 provided their e-mail address and received the survey; 118 responded (47% of the total). Of these, 25% were not aware of the recent NCCN recommendation, 55% were already prescribing low-dose abiraterone when resources were limited, 7% had already changed their practice, and 29% agreed to switch to a universal practice of using low-dose abiraterone with food; 9% of practitioners would not use low-dose abiraterone. Estimated mean per patient savings was US$3,640, with annual savings of US$182 million in India. CONCLUSION: Use of lower-dose abiraterone would increase access to treatment in India and globally and lead to large cost savings.
