RESUMO

BACKGROUND: Cisplatin and doxorubicin are integral components of chemotherapy regimens in the treatment of osteosarcoma. Choice of third agent high-dose methotrexate (HDMTX) or an alkylating agent such as ifosfamide is debatable. The present study compared the impact of MAP (HDMTX-doxorubicin-cisplatin) and IAP (ifosfamide-doxorubicin-cisplatin) chemotherapy regimens on toxicity and survival in children and adolescents with osteosarcoma. MATERIALS AND METHODS: This was a retrospective study including patients 18 years and younger with osteosarcoma during the study period. Clinical, demographic, chemotherapy regimen, and surgical details and treatment-related toxicity were retrieved from hospital medical records. Prognostic factors affecting overall survival (OS) and event-free survival (EFS) were analyzed. RESULTS: Among 102 patients included in the study, 59 (57.8%) and 43 (42.2%) patients were treated with MAP and IAP regimens, respectively. Two groups were comparable in terms of pretreatment characteristics and surgical treatment. Overall, 95.9% patients underwent limb salvage surgery. There was a statistically increased incidence in supportive care admissions and delay in starting the next cycle of chemotherapy in the MAP group. Among the MAP cohort, the 5-year OS and EFS were 62% and 55% compared with 47% and 44%, respectively, in the IAP cohort (P=0.143 and 0.316, respectively). On univariate and multivariate analyses, statistically significant factors affecting EFS of the whole group included tumor size, stage, site of metastasis, histologic necrosis, and type of surgery. CONCLUSIONS: OS and EFS with both regimens were similar. However, the MAP regimen was associated with a statistically significant increase in incidence of supportive care admissions, delay in next cycle of chemotherapy, and predicted higher cost of treatment.

RESUMO

BACKGROUND & OBJECTIVES: Gallbladder (GBC) is an aggressive form of cancer and most patients present with advanced unresectable disease due to lack of early signs and symptoms. This retrospective study was conducted to present the treatment outcomes with three lines of chemotherapies in a subset of patients with advanced, unresectable GBC with the primary objective to determine the response rates with nab-paclitaxel as the third-line chemotherapy after failure of the first-line gemcitabine and platinum and the second-line FOLFOX-4 (oxaliplatin, leucovorin and 5-FU) therapy. Another objective was to evaluate the toxicity, progression-free survival (PFS) and overall survival (OS). METHODS: Treatment-naive patients with histologically proven inoperable GBC treated with gemcitabine/platinum, FOLFOX-4 and nab-paclitaxel as the first-, second- and third-line chemotherapy were included in this study. The dose of gemcitabine and cisplatin or carboplatin was 1 g/m[2] on days 1 and 8 and 75 mg/m[2] (or target AUC of 5) on day 1, in a 21-day cycle. FOLFOX-4 was administered every two weeks and nab-paclitaxel was administered as 125 mg/m[2] on days 1, 8 and 15 in a 28-day cycle. RESULTS: There were eight men and 13 women with a median age of 57 yr who received nab-paclitaxel therapy. The overall response rate of the first-, second- and third-line chemotherapy was 61.9, 57.1 and 52.4 per cent, respectively. The median PFS for the gemcitabine/platinum, FOLFOX-4 and nab-paclitaxel therapy was 5.5, 5.4 and 2.9 months, respectively. The median OS with three lines of therapies was 14.0 months. Common Terminology Criteria (CTC) grade 3 or 4 haematological toxicities were observed in 28.6, 38.1 and 23.8 per cent of patients on gemcitabine/platinum, FOLFOX-4 and nab-paclitaxel therapy, respectively. INTERPRETATION & CONCLUSIONS: Our study suggests the clinical benefit of nab-paclitaxel chemotherapy in prolonging OS in a selected subgroup of advanced, unresectable GBC patients after failure of the first-line gemcitabine and platinum and the second-line FOLFOX-4 therapy.

RESUMO

Human epidermal growth factor receptor 2 (HER-2) is an established prognostic and predictive biomarker for breast cancer. To ensure accuracy and uniformity for HER-2 testing, ASCO/CAP published guidelines in 2007 which were updated in 2013 and recently in 2018. In this first study from Indian Oncology center, we evaluated the impact of 2018 ASCO/CAP guidelines. We found a substantial decrease in equivocal IHC cases (P-value < .00001). On reclassification, a total of 5.6% cases from equivocal and positive categories (2013 guidelines) shifted to the negative FISH result category (P-value < .0001), with adoption of 2018 guidelines and eliminated the double equivocal cases.

RESUMO

It is often difficult for people with cancer to make decisions for their care. The aim of this review is to understand the importance of shared decisionmaking (SDM) in Indian clinical scenario and identify the gaps when compared to practices in the Western world. A systematic search (2000-2019) was executed in Medline and Google Scholar using predefined keywords. Of the approximate 400 articles retrieved, 43 articles (Indian: 5; Western: 38) were selected for literature review. Literature review revealed the paucity of information on SDM in India compared to the Western world data. This may contribute to patientreported physical or psychological harms, life disruptions, or unnecessary financial costs. Western world data demonstrate the involvement and sharing of information by both patient and physician, collective efforts of the two to build consensus for preferred treatment. In India, involvement of patients in the planning for treatment is largely limited to tertiary care centers, academic institutes, or only when the cost of therapy is high. In addition, cultural beliefs and prejudices impact the extent of participation and engagement of a patient in disease management. Communication failures have been found to strongly correlate with the medicolegal malpractice litigations. Research is needed to explore ways to how to incorporate SDM into routine oncology practice. India has a high unmet need towards SDM in diagnosis and treatment of cancer. Physicians need to involve patients or their immediate family members in decision making, to make it a patient-centric approach as well. SDM enforces to avoid uninformed decisionmaking or a lack of trust in the treating physician's knowledge and skills. Physician and patient education, development of tools and guiding policies, widespread implementation, and periodic assessments may advance the practice of SDM.

RESUMO

AIMS: To investigate Ki-67 index with regard to its ability to predict achievement of pathologic complete response (pCR) to neoadjuvant chemotherapy (NACT) in breast cancer patient. MATERIAL AND METHODS: It was a prospective observational study, conducted in Department of Medical Oncology, Rajiv Gandhi Cancer Institute & Research Center (RGCIRC), New Delhi from February 2014 to March 2016. A total of 134 patients with Stage II/III breast cancer who underwent NACT followed by surgery at our center were enrolled and analyzed. Before starting the treatment, clinical, tumor-related and treatment-related factors were recorded. Response evaluation was done clinically and radiologically after completion of NACT and pathologically on the surgical specimen. We calculated Ki-67 cut-off of 35% to label it as high by area under Receiver operating characteristic curve analysis for prediction of pCR. RESULTS: Clinical complete response (cCR) was observed in 35/134 (26.1%) patients while pCR was observed in 32/134 (23.9%) patients. On univariate analysis, higher grade (III), high Ki-67 index (>35%) and number of chemotherapy cycles (>3) were associated with better CCR rates. On multivariate analysis, number of chemotherapy cycles (>3) and high Ki-67 index (>35%) were independent predictive factors. For the predictive factors of pCR, univariate analysis showed grade (III), estrogen receptor/progesterone receptor negativity, HER-2 positivity, number of chemotherapy cycles (>3), TNBC and high Ki-67 index (>35%) to be associated with higher pCR rates. On multivariate analysis, Ki-67 index >35% and HER-2 positivity were the only independent predictive factors of pCR. CONCLUSIONS: We suggest 35% as best cut-off for Ki-67 expression for predicting response to NACT and achievement of pCR. Validation of this cut-off is required in larger studies.

RESUMO

OBJECTIVE: There is no standard second-line chemotherapy after progression on first-line therapy including gemcitabine and platinum combination in advanced gall bladder cancer patients. So this study was undertaken to assess the efficacy and safety of FOLFOX-4 regimen in this setting. METHODS: In this observational study, patients with performance status ≤2, who progressed on first-line therapy, were enrolled from May 2010 to June 2014. FOLFOX-4 based treatment was administered until progression, unacceptable toxicity or up to 12 cycles. RESULTS: A total of 66 patients were enrolled in this study. The median age of patients was 52.5 years (32-66 years),of which 24 (36.36%) were males and 42 (63.63%) were females. The median number of cycles could be given were 9.5 (2-12). Only 43.93% patients in this study completed full 12 cycles of chemotherapy. Sixteen patients (24.24%) in this study required the dose reduction at least in one cycle of chemotherapy due to toxicities. Disease control rate was seen in 39 (59.09%) patients, with complete response in none, partial response in 16 (24.24%), stable disease in 23 (34.84%) and progressive disease in 27 (40.90%) patients. The median progression free survival was 3.9 months; median overall survival was 7.6 months. The main Grade 3/4 side effects seen were hematological in 31.81% (n = 21) and gastrointestinal in 25.75% (n = 17) patients. Majority of patients (46%) had Grade 1/2 peripheral neuropathy. CONCLUSIONS: FOLFOX-4 is an effective and well-tolerated regimen as a second-line treatment in advanced gall bladder cancer patients. Further studies are required, especially in the Indian subcontinent.

RESUMO

BACKGROUND: Longer duration of first-line chemotherapy for patients with metastatic breast cancer is associated with prolonged overall survival and improved progression-free survival. We investigated capecitabine added to maintenance bevacizumab after initial treatment with bevacizumab and docetaxel in this setting. METHODS: We did this open-label randomised phase 3 trial at 54 hospitals in Brazil, China, Egypt, France, Hong Kong, India, Italy, Poland, Spain, and Turkey. We enrolled patients with HER2-negative measurable metastatic breast cancer; each received three to six cycles of first-line bevacizumab (15 mg/kg) and docetaxel (75-100 mg/m(2)) every 3 weeks. Progression-free patients were randomly assigned with an interactive voice-response system by block (size four) randomisation (1:1) to receive either bevacizumab and capecitabine or bevacizumab only (bevacizumab 15 mg/kg on day 1; capecitabine 1000 mg/m(2) twice per day on days 1-14, every 3 weeks) until progression, stratified by oestrogen receptor status (positive vs negative), visceral metastases (present vs absent), response status (stable disease vs response vs non-measurable), and lactate dehydrogenase concentration (≤1·5 vs >1·5 × upper limit of normal). Neither patients nor investigators were masked to allocation. The primary endpoint was progression-free survival (from randomisation) in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT00929240. FINDINGS: Between July 16, 2009, and March 7, 2011 (when enrolment was prematurely terminated), 284 patients received initial bevacizumab and docetaxel; 185 (65%) were randomly assigned (91 to bevacizumab and capecitabine versus 94 to bevacizumab only). Progression-free survival was significantly longer in the bevacizumab and capecitabine group than in the bevacizumab only group (median 11·9 months [95% CI 9·8-15·4] vs 4·3 months [3·9-6·8]; stratified hazard ratio 0·38 [95% CI 0·27-0·55]; two-sided log-rank p<0·0001), as was overall survival (median 39·0 months [95% CI 32·3-not reached] vs 23·7 months [18·5-31·7]; stratified HR 0·43 [95% CI 0·26-0·69]; two-sided log-rank p=0·0003). Results for time to progression were consistent with those for progression-free survival. 78 (86%) patients in the bevacizumab and capecitabine group and 72 (77%) in the bevacizumab only group had an objective response. Clinical benefit was recorded in 92 (98%) patients in the bevacizumab alone group and 90 (99%) in the bevacizumab and capecitabine group. Mean change from baseline in global health score did not differ significantly between groups. Grade 3 or worse adverse events during the maintenance phase were more common with bevacizumab and capecitabine than with bevacizumab only (45 [49%] of 91 patients vs 25 [27%] of 92 patients). The most common grade 3 or worse events were hand-foot syndrome (28 [31%] in the bevacizumab and capecitabine group vs none in the bevacizumab alone group), hypertension (eight [9%] vs three [3%]), and proteinuria (three [3%] vs four [4%]). Serious adverse events were reported by ten (11%) patients in the bevacizumab and capecitabine group and seven (8%) patients in the bevacizumab only group. INTERPRETATION: Despite prematurely terminated accrual and the lack of information about post-progression treatment, both progression-free survival and overall survival were significantly improved with bevacizumab and capecitabine compared with bevacizumab alone as maintenance treatment. These results might inform future maintenance trials and current first-line treatment strategies for HER2-negative metastatic breast cancer. FUNDING: F Hoffmann-La Roche.

RESUMO

BACKGROUND: The present study observed the expression levels of epidermal growth factor receptor (EGFR), p53, Bcl2, vascular endothelial growth factor (VEGF), cyclooxygenase-2 (cox-2), cyclin D1, human epidermal receptor-2 (HER-2) and Ki-67 in gallbladder carcinoma (GBC) and their association with clinicopathological profiles and disease outcomes. MATERIALS AND METHODS: Fifty consecutive samples of cholecystectomy/biopsies from GB bed (archived formalin fixed paraffin embedded tissue blocks of different stages of GBC) were included, and patient details related to their demographic profile, investigations, tumor profile, treatment, and follow-up were recorded. Immunohistochemistry was performed to study the expression levels. RESULTS: Overexpression of EGFR, p53, Bcl2, VEGF, cox-2, cyclin D1 and HER-2 was observed as 74%, 44%, 8%, 34%, 66%, 64%, and 4%, respectively. Association of Bcl2 overexpression in mucinous morphology (40%, P = 0.045), cox-2 overexpression in early stage (I/II) tumors (87.5%, P = 0.028) and VEGF overexpression in alive patients (47.1%, P = 0.044) was observed. Co-expression of EGFR and p53 were statistically significant (P = 0.033). Ki-67 labeling index was significantly higher in patients in age group <40 years (P = 0.027), and poorly differentiated tumors (P = 0.023). Advanced disease and poorly differentiated tumors showed a significantly poor median survival (P < 0.05). CONCLUSION: EGFR, cox-2 and cyclin D1 were largely overexpressed. Advanced tumor stages and poorly differentiated tumors are predictors of poor survival.

RESUMO

BACKGROUND: Adenocarcinoma, a subgroup of non-small cell lung cancer, is the most frequent form occurring in the non-smokers. Mutation in tyrosine kinase domain of epidermal growth factor receptor (EGFR) has been a common feature observed in lung adenocarcinoma. The study was carried out to detect the prevalence of EGFR mutation in lung adenocarcinoma. MATERIALS AND METHODS: EGFR mutation status in 166 lung adenocarcinoma patients was obtained retrospectively. Mutation tests were performed on paraffin embedded tissue blocks as a routine diagnostic procedure by polymerase chain reaction followed by direct nucleotide sequencing. Patient's demographics and other clinical details were obtained from the medical records. RESULTS: EGFR mutation was detected in 43/166 (25.9%) patients. Gender wise mutation was observed as 18/55 (32.7%) in females and 25/111 (22.5%) in males. Overall, EGFR mutation was correlated with never smokers and distant metastasis (P < 0.05), but not associated with the gender, disease stage and pleural effusion. Exon 19 deletions were significantly correlated with females, never smokers, pleural effusion and distant metastasis (P < 0.05). However, point mutation on exon 21 did not show any statistical association with the above variables. Median overall survival was 22 months (95% confidence interval, 15.4-28.6). Female sex, EGFR mutation and absence of metastasis are associated with good prognosis. CONCLUSION: EGFR mutation in lung adenocarcinoma was higher in never smokers, females and patients with distant metastasis. However, it was not linked with tobacco smoking. The prevalence of EGFR mutation observed is in range with the previously published reports from the Asian countries.

RESUMO

Dinesh Chandra DovalBackground Circulating tumor cells (CTCs) in the peripheral blood may play a major role in the metastatic spread of breast cancer. This study was conducted to assess the role of CTCs to determine the prognosis in terms of survival in metastatic breast cancer patients. Methods This prospective study of 36 patients was conducted at the Hospital from April 2016 to May 2018. Details of each patient related to the demographic profile, tumor type, treatment, and follow-up information were recorded. The number of CTCs in the peripheral blood was measured by Celsee PREP 400 sample processing system and Celsee Analyzer imaging station. Results There was a positive correlation between the number of site of metastasis with number of CTCs ( p -value < 0.001). In the patients with clinical/partial response, a significant reduction in the number of CTCs after 1 month of therapy was observed ( p -value = 0.003). When the number of CTCs at baseline and 6 months were compared with the positron emission tomography response at 6 months, a statistically significant difference in CTCs in patients having partial response after 6 months was observed ( p -value = 0.001). On comparison with the responder groups, a statistically significant reduction in CTCs at baseline and 6 months was observed ( p -value = 0.001). Patients with CTCs less than 5 and more than or equal to 5 after 1 month of treatment had a mean progression-free survival of 11.1 months and 7.5 months ( p -value = 0.04) and a mean overall survival of 11.6 and 9.6 months ( p -value = 0.08), respectively. Conclusion Assessment of CTCs provides a more quantifiable response than radiographic evaluation and at a much earlier time point and is also a better predictor of survival.

RESUMO

Extraosseous sarcoma of the breast is an infrequent entity and a harbinger of poor prognosis. Histogenesis of this tumor is uncertain, and it can arise both in denovo and metastatic settings. Morphologically, it is indistinguishable from its skeletal counterpart and clinically, it presents like any other subtype of breast cancer. Tumor recurrence with a propensity for hematogenous rather than lymphatic spread plagues with this malicious disease. Treatment guidelines are mainly extrapolations from those of treatment of other extra-skeletal sarcomas as literature is limited in this context. In this study, it was aimed to present two clinical cases with similar clinical profiles and different treatment outcomes. The intent of this case report is to contribute to the limited database available for management of this rare disease.

RESUMO

AIM: Palbociclib was approved in the United States in 2015 to treat estrogen receptor-positive/human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC). This study evaluated outcomes and safety in patients treated with palbociclib in Australia and India with hormone receptor-positive (HR+)/HER2- ABC before palbociclib became commercially available. METHODS: Postmenopausal women (≥18 years) with HR+/HER2- ABC who were appropriate candidates for letrozole therapy received palbociclib 125 mg once daily for 21 days followed by 7 days off, and letrozole 2.5 mg once daily (continuous). Safety, tumor response, and patient-reported outcomes (Australian cohort) were evaluated. RESULTS: In total, 252 patients received palbociclib plus letrozole (Australia, n = 152; India, n = 100). More patients in the Australian versus Indian cohort had received prior chemotherapy (advanced/metastatic setting: 45.9% vs. 32.0%), endocrine therapy (advanced/metastatic setting: 63.2% vs. 54.3%), and advanced/metastatic therapies (61.8% vs. 31.0%). The most frequently reported all-grade palbociclib-related treatment-emergent adverse events were neutropenia (66.7%), fatigue (35.3%), and stomatitis (26.6%); grade 3/4 neutropenia was reported as palbociclib-related in 62.7% of patients. Febrile neutropenia was reported in six patients (2.4%). Eight patients (3.2%) discontinued because of an adverse event. The objective response rate was 19.4% (95% CI, 14.7%-24.9%) overall and 2.3% in Australian patients with ≥2 lines of prior therapy for metastatic disease. Patient-reported quality of life scores were maintained throughout the study. CONCLUSIONS: In an expanded access setting in Australia and India, palbociclib plus letrozole was well tolerated in patients with HR+/HER2- ABC, with a safety profile consistent with previous reports.

RESUMO

Although majority of lung cancers have distant metastasis at the time of initial diagnosis, colonic metastases are extremely rare. This report presents a rare clinical case which presented with lower limb deep vein thrombosis and found to have colon polyp incidentally detected while evaluating for occult blood positive in stool. Histopathology of the polyp was suggestive of lung primary and on further evaluation PET scan was suggestive of left lung mass with widespread distant metastasis.

RESUMO

INTRODUCTION: We aimed to interpret MR mammography (MRM) using the Kaiser scores for equivocal or inconclusive lesions on mammography (MG). METHODS: Retrospective IRB-approved evaluation of 3623 MG for which MRM was deployed as a problem-solving tool, after inclusion-exclusion criteria were met. Three readers with different levels of experience assigned a final score from 1 to 11 based on the previously established tree classification system. Area under the curve (AUC) derived from receiver operating characteristic (ROC) analysis was used to determine the overall diagnostic performance for all lesions and separately for mass and non-mass enhancement. Sensitivity, specificity, and likelihood ratio values were obtained at different cut-off values of >4, > 5, and > 8 to rule in and rule out malignancy. RESULT: Histopathology of 183 mass and 133 non-mass enhancement (NME) lesions show benign etiology in 95 and malignant in 221. The AUC was 0.796 [0.851 for mass and 0.715 for NME]. Applying the Kaiser score upgraded 202 lesions with correct prediction in 77 %, and downgraded 28 lesions with correct prediction in 60.8 %. Using a score <5 instead of <4 to rule out malignancy improved our diagnostic ability to correctly identify 100 % benign lesions. Applying Kaiser score correctly downgraded 60.8 % (17/28) lesions; thus avoiding biopsies in these. Using a high cut-off value>8 to rule-in malignancy, we correctly identified 59.7 % of lesions with 80 % specificity and positive likelihood ratio of 3. CONCLUSION: The Kaiser score has clinical translation benefits when used as a problem-solving tool for inconclusive MG findings.

RESUMO

The combination of cyclin dependent kinase 4/6 inhibitors with endocrine therapy is the standard therapy in hormone receptor positive HER-2 negative metastatic breast cancer (HR+/HER2- MBC). Several randomized trials have shown the benefits of this combination, however, real world evidence in the Indian patients is warranted. The present study reports the largest real world multicentric data from Indian population on the use of Palbociclib in HR+/HER2- MBC. A multicentric study on the HR+/HER2- MBC patients who received palbociclib with hormonal agent (Aromatase inhibitors/Fulvestrant) between February 2017 and May 2020 was conducted. Clinical and demographic information and survival data was retrieved from the Hospital medical records. Among a total of 188 patients, 57% patients were premenopausal and 17% patients had bone only disease. Altogether, 115 (61%) patients received palbociclib with Aromatase inhibitors in the first line whereas 73 (39%) patients received it in the second line with Fulvestrant. The median follow up period with advanced disease was 13 months. The median progression free survival in the first line and second line was 20.2 months and 12 months, respectively (p-value < 0.0001). The objective response rate was 80% and 47.9% in first and second lines, respectively. Dose interruptions/ discontinuation were done in 14.9% and 2.7% patients in the first and second lines, respectively. In terms of toxicity, 10% patients had grade 3-4 adverse events. The present real world data of the use of palbociclib in Indian population suggests similar effectiveness to previously published real world evidences and has been adapted as the standard of care in the first and second line treatment of HR+/HER2- MBC.

RESUMO

BACKGROUND: Uterine carcinosarcoma (UCS) is a rare and aggressive malignancy, and there are no existing standard guidelines for adjuvant therapy. Doublet chemotherapy regimens are most favored in adjuvant setting; however, given the early chances of distant recurrences, does a triple-drug adjuvant chemotherapy improve disease-free survival (DFS), remains to be seen. Our aim of the study is to compare and review different adjuvant regimens used in UCS. METHODS: Retrospective chart analysis included 37 optimally staged UCS patients. Each of them had either received paclitaxel plus carboplatin (PC) or paclitaxel, ifosfamide, and cisplatin (TIP). A toxicity analysis was charted as per common terminology criteria for adverse events (CTCAE) 4 criteria. A survival analysis was done by the Kaplan-Meier method, and log-rank test was used for comparison of two variables. RESULTS: Incidence of UCS was 4.1% and mean age (standard deviation) was 58.73 ± 6.3 (range 42 - 71) years. TIP and PC chemotherapies were given to 22 and 15 patients, respectively. Five-year DFS and overall survival for TIP versus PC were 38.2% versus 35.9% (P = 0.118) and 49% versus 50.3% (P = 0.306), respectively, and for Stage I, II versus Stage III was 78.8% versus 12.7%(P = 0.001) and 92.3% versus 34.2% (P = 0.002), respectively. However, in advanced disease (Stage III), there is a trend toward DFS advantage of triple-drug adjuvant regimen (Hazards ratio (HR) = 0.35, 95% confidence interval (CI) = 0.12-1.07). Grade 3 and 4 toxicities were seen in 54.5% patients of TIP chemotherapy group and in 13.3% patients of the PC chemotherapy (P = 0.012). CONCLUSION: Triple-drug adjuvant chemotherapy (TIP) confers no survival advantage over doublet chemotherapy (PC), and in turn, increases the grade 3/4 toxicity in the adjuvant setting of optimally staged UCS patients.

RESUMO

Accurate recurrence risk assessment in hormone receptor positive, HER2/neu negative breast cancer is critical to plan precise therapy. CanAssist Breast (CAB) assesses recurrence risk based on tumor biology using artificial intelligence-based approach. We report CAB risk assessment correlating with disease outcomes in multiple clinically high- and low-risk subgroups. In this retrospective cohort of 925 patients [median age-54 (22-86)] CAB had hazard ratio (HR) of 3 (1.83-5.21) and 2.5 (1.45-4.29), P = 0.0009) in univariate and multivariate analysis. CAB's HR in sub-groups with the other determinants of outcome, T2 (HR: 2.79 (1.49-5.25), P = 0.0001); age [< 50 (HR: 3.14 (1.39-7), P = 0.0008)]. Besides application in node-negative patients, CAB's HR was 2.45 (1.34-4.47), P = 0.0023) in node-positive patients. In clinically low-risk patients (N0 tumors up to 5 cms) (HR: 2.48 (0.79-7.8), P = 0.03) and with luminal-A characteristics (HR: 4.54 (1-19.75), P = 0.004), CAB identified >16% as high-risk with recurrence rates of up to 12%. In clinically high-risk patients (T2N1 tumors (HR: 2.65 (1.31-5.36), P = 0.003; low-risk DMFS: 92.66 ± 1.88) and in women with luminal-B characteristics (HR: 3.24; (1.69-6.22), P < 0.0001; low-risk DMFS: 93.34 ± 1.34)), CAB identified >64% as low-risk. Thus, CAB prognostication was significant in women with clinically low- and high-risk disease. The data imply the use of CAB for providing helpful information to stratify tumors based on biology incorporated with clinical features for Indian patients, which can be extrapolated to regions with similarly characterized patients, South-East Asia.

RESUMO

Incidence of human papillomavirus (HPV)-associated oral cancers is on the rise. However, epidemiological data of this subset of cancers are limited. Dental hospital poses a unique advantage in detection of HPV-positive oral malignancies. We assessed the utility of formalin-fixed paraffin-embedded (FFPE) tissues, which are readily available, for evaluation of high-risk HPV infection in oral cancer. For protocol standardization, we used 20 prospectively collected paired FFPE and fresh tissues of histopathologically confirmed oral cancer cases reported in Oral Medicine department of a dental hospital for comparative study. Only short PCRs (~ 200 bp) of DNA isolated using a modified xylene-free method displayed a concordant HPV result. For HPV analysis, we used additional 30 retrospectively collected FFPE tissues. DNA isolated from these specimens showed an overall 23.4% (11/47) HPV positivity with detection of HPV18. Comparison of HPV positivity from dental hospital FFPE specimens with overall HPV positivity of freshly collected oral cancer specimens (n = 55) from three cancer care hospitals of the same region showed notable difference (12.7%; 7/55). Further, cancer hospital specimens showed HPV16 positivity and displayed a characteristic difference in reported sub-sites and patient spectrum. Overall, using a xylene-free FFPE DNA isolation method clubbed with short amplicon PCR, we showed detection of HPV-positive oral cancer in dental hospitals.

RESUMO

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.
