Pan-Asian adapted ESMO Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with early breast cancer.

The European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with early breast cancer were updated and published online in 2023, and adapted, according to previously established standard methodology, to produce the Pan-Asian adapted (PAGA) ESMO consensus guidelines for the management of Asian patients with early breast cancer. The adapted guidelines presented in this manuscript represent the consensus opinions reached by a panel of Asian experts in the treatment of patients with breast cancer representing the oncological societies of China (CSCO), Indonesia (ISHMO), India (ISMPO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO), co-ordinated by ESMO and KSMO. The voting was based on scientific evidence and was independent of the current treatment practices, drug access restrictions and reimbursement decisions in the different Asian regions represented by the 10 oncological societies. The latter are discussed separately in the manuscript. The aim is to provide guidance for the optimisation and harmonisation of the management of patients with early breast cancer across the different regions of Asia, drawing on the evidence provided by both Western and Asian trials, whilst respecting the differences in screening practices, molecular profiling, as well as the age and stage at presentation. Attention is drawn to the disparity in the drug approvals and reimbursement strategies, between the different regions of Asia.

Challenges in oncology career: are we closing the gender gap? Results of the new ESMO Women for Oncology Committee survey.

BACKGROUND: Following a European Society for Medical Oncology Women for Oncology (ESMO W4O) survey in 2016 showing severe under-representation of female oncologists in leadership roles, ESMO launched a series of initiatives to address obstacles to gender equity. A follow-up survey in October 2021 investigated progress achieved. MATERIALS AND METHODS: The W4O questionnaire 2021 expanded on the 2016 survey, with additional questions on the impact of ethnicity, sexual orientation and religion on career development. Results were analysed according to respondent gender and age. RESULTS: The survey sample was larger than in 2016 (n = 1473 versus 482), especially among men. Significantly fewer respondents had managerial or leadership roles than in 2016 (31.8% versus 51.7%). Lack of leadership development for women and unconscious bias were considered more important in 2021 than in 2016. In 2021, more people reported harassment in the workplace than in 2016 (50.3% versus 41.0%). In 2021, ethnicity, sexual orientation and religion were considered to have little or no impact on professional career opportunities, salary setting or related potential pay gap. However, gender had a significant or major impact on career development (25.5% of respondents), especially in respondents ≤40 years of age and women. As in 2016, highest ranked initiatives to foster workplace equity were promotion of work-life balance, development and leadership training and flexible working. Significantly more 2021 respondents (mainly women) supported the need for culture and gender equity education at work than in 2016. CONCLUSIONS: Gender remains a major barrier to career progression in oncology and, although some obstacles may have been reduced since 2016, we are a long way from closing the gender gap. Increased reporting of discrimination and inappropriate behaviour in the workplace is a major, priority concern. The W4O 2021 survey findings provide new evidence and highlight the areas for future ESMO interventions to support equity and diversity in oncology career development.

Female leadership in oncology-has progress stalled? Data from the ESMO W4O authorship and monitoring studies.

BACKGROUND: Exploratory research showed that female oncologists are frequently under-represented in leadership roles. European Society for Medical Oncology (ESMO) Women for Oncology (W4O) therefore implemented gender equality programs in career development and established international studies on female representation at all stages of the oncology career pathway. METHODS: For 2017-2019, data were collected on (i) first and last authorship of publications in five major oncology journals and (ii) representation of women in leadership positions in oncology-as invited speakers at National/International congresses, board members or presidents of National/International societies and ESMO members. The 2015/2016 data from the first published W4O Study were incorporated for comparisons. RESULTS: Across 2017-2019, female oncologists were significantly more likely to be first than last authors (P < 0.001). The proportion of female first authors was similar across years: 38.0% in 2017, 37.1% in 2018, 41.0% in 2019 (P = 0.063). The proportion of female last authors decreased from 30.4% in 2017 to 24.2% in 2018 (P = 0.0018) and increased to 28.5% in 2019 (P = 0.018). Across 2015-2019, invited speakers at International/National oncology congresses were significantly less likely to be female than male (P < 0.001; 29.7% in 2015 to 36.8% in 2019). Across 2016-2019, board members of International/National oncology societies were significantly less likely to be female than male (P < 0.001; 26.8% in 2016 to 35.8% in 2019). There were statistically significant increasing trends in female speakers and board members across the study periods (P < 0.001 for both). Societies with a female president had a higher proportion of female board members across these periods (P = 0.026). CONCLUSIONS: Reported progress towards gender equality in career development in oncology is real but slow. Women in leadership positions are essential for encouraging young women to aspire to and work towards similar or greater success. Therefore, continued monitoring is needed to inform ESMO W4O initiatives to promote gender balance at all stages of the career pathway.

Epithelioid hemangioendothelioma, an ultra-rare cancer: a consensus paper from the community of experts.

Epithelioid hemangioendothelioma (EHE) is an ultra-rare, translocated, vascular sarcoma. EHE clinical behavior is variable, ranging from that of a low-grade malignancy to that of a high-grade sarcoma and it is marked by a high propensity for systemic involvement. No active systemic agents are currently approved specifically for EHE, which is typically refractory to the antitumor drugs used in sarcomas. The degree of uncertainty in selecting the most appropriate therapy for EHE patients and the lack of guidelines on the clinical management of the disease make the adoption of new treatments inconsistent across the world, resulting in suboptimal outcomes for many EHE patients. To address the shortcoming, a global consensus meeting was organized in December 2020 under the umbrella of the European Society for Medical Oncology (ESMO) involving >80 experts from several disciplines from Europe, North America and Asia, together with a patient representative from the EHE Group, a global, disease-specific patient advocacy group, and Sarcoma Patient EuroNet (SPAEN). The meeting was aimed at defining, by consensus, evidence-based best practices for the optimal approach to primary and metastatic EHE. The consensus achieved during that meeting is the subject of the present publication.

Has COVID-19 had a greater impact on female than male oncologists? Results of the ESMO Women for Oncology (W4O) Survey.

BACKGROUND: European Society for Medical Oncology Women for Oncology (ESMO W4O) research has previously shown under-representation of female oncologists in leadership roles. As early reports suggested disproportionate effects of the COVID-19 pandemic on women, the ESMO W4O Committee initiated a study on the impact of the pandemic on the lives of female and male oncologists. METHODS: A questionnaire was sent to ESMO members and put on the ESMO website between 8 June 2020 and 2 July 2020. Questions focused on the working (hospital tasks, laboratory tasks, science) and home (household management, childcare, parent care, personal care) lives of oncologists during and after COVID-19-related lockdowns. RESULTS: Of 649 respondents, 541 completed the questionnaire. Of these, 58% reported that COVID-19 had affected their professional career, 83% of whom said this was in a negative way (85% of women versus 76% of men). Approximately 86% reported that COVID-19 had changed their personal life and 82% their family life. Women were again significantly more affected than men: personal life (89% versus 78%; P = 0.001); family life (84% versus 77%; P = 0.037). During lockdowns, women reported increased time spent on hospital and laboratory tasks compared with men (53% versus 46% and 33% versus 26%, respectively) and a significantly higher proportion of women than men spent less time on science (39% versus 25%) and personal care (58% versus 39%). After confinement, this trend remained for science (42% versus 23%) and personal care (55% versus 36%). CONCLUSIONS: The COVID-19 pandemic has adversely affected the professional and home lives of oncologists, especially women. Reduced research time for female oncologists may have long-lasting career consequences, especially for those at key stages in their career. The gender gap for promotion to leadership positions may widen further as a result of the pandemic.

"Randomised controlled trial of scalp cooling for the prevention of chemotherapy induced alopecia".

BACKGROUND: Randomized controlled trials (RCT) of scalp cooling (SC) to prevent chemotherapy induced alopecia (CIA) did not evaluate its effect on hair regrowth (HR) and was conducted in a predominantly taxane (T) treated population. We conducted an RCT of SC in a setting of anthracycline (A) and taxane chemotherapy (CT) and assessed its effect on CIA and HR. METHODS: Non-metastatic breast cancer women undergoing (neo) adjuvant CT were randomized to receive SC using the Paxman scalp cooling system during every cycle of CT, or no SC. The primary end point (PEP) was successful hair preservation (HP) assessed clinically and by review of photographs after CT. HR was assessed at 6 and 12 weeks. RESULTS: 51 patients were randomized to SC (34) or control arm (17) in a 2:1 ratio. Twenty-five (49%) patients received A followed by T and the two arms were balanced with respect to this factor. HP rate was significantly higher in SC arm compared to control arm (56.3% vs 0%, P = 0.000004). HR was higher in SC arm compared to control at 6 weeks (89% vs 12%; P < 0.001) and 12 weeks (100% vs 59%, P = 0.0003). Loss of hair at PEP evaluation, which was a quality of life measure, was significantly lower in SC versus control arm (45% vs 82%, P = 0.016). There were no grade 3-4 cold related adverse effects. CONCLUSIONS: Women with breast cancer receiving A or T chemotherapy receiving SC were significantly more likely to have less than 50% hair loss after CT, superior hair regrowth and improvement in patient reported outcomes, with acceptable tolerance. It merits wider usage.

Practical consensus recommendations regarding the use of hormonal therapy in metastatic breast cancer.

Metastatic breast cancer (MBC) is cancer that has spread from the breast to another part of the body or has come back in another distant location. Treatment options for MBC depend on several factors. One of these factors is the levels of hormone receptors (HRs) in the tumor. Cancers with high levels of HRs, called HR-positive, use the hormones estrogen and progesterone to grow and spread. Hormonal therapy is a type of treatment specifically for HR-positive breast cancer. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations in regards with the use of hormonal therapy and the management of HR-positive MBC for the benefit of community oncologists.

Histopathologic review of 400 biopsies and resection specimens of trunk and extremity-based soft tissue tumors.

AIMS: To review various pathologic parameters in diagnosed cases of trunk and extremity-based soft tissue tumors (STTs), in order to identify concordance rate between initial biopsy and resection specimen and discrepancies between initial and review diagnosis, by a specialist pathologist. MATERIALS AND METHODS: Over a 2-year-period, 400 retrospectively diagnosed STTs (553 specimens) including referral and "in-house" cases were studied. The reviewing specialist pathologist was blinded to the initial diagnoses. Discordances including discrepancies and deficiencies were defined as major and minor. Major discrepancies included those that could lead to significant treatment changes. True discrepancies were those related to sampling issues between the biopsies and resection specimens. Deficiencies relating to tumor subtyping, sarcoma grading, documentation of tumor size, and marginal status (in resections) were subdivided as major and minor. RESULTS: Most cases (328, 82%) were sarcomas (most common, synovial sarcoma; most common Stage, III), followed by benign tumors (36, 9%) (most common, schwannoma) and intermediate malignancies (32, 8%) (most common, fibromatosis). Within STTs, liposarcomas, neural tumors, and undifferentiated pleomorphic sarcomas were relatively more frequently associated with discrepancies. Percentage of cases with major discordances between the referral reports (100 cases) and review diagnosis was 60%. Percentage of cases with major discordances between the specialist and other oncopathologists was 11%. True discrepancies were observed in 20 (5%) cases. The association of type of specimen with the rate of discordance was not significant (P = 0.114). CONCLUSIONS: Diagnoses of STTs are fraught with errors mostly from general pathologists, followed by nonspecialist oncopathologists. These findings reinforce the need for reporting of STTs, especially sarcomas, by specialist pathologists.

Everolimus in heavily pretreated metastatic breast cancer: Is real world experience different?

BACKGROUND: Drugs targeting mammalian target of rapamycin signaling pathway have been recently approved for treatment of hormone receptor (HR) positive metastatic breast cancer (MBC). However, there is lack of real world data from India on the use of this therapeutic strategy. MATERIALS AND METHODS: A retrospective analysis of MBC patients who had recurrence or progression while receiving aromatase inhibitors (AI's) and further treated with everolimus and either tamoxifen/AI/fulvestrant between March 2012 and June 2014, was undertaken. RESULTS: There were 41 patients with median age 55 years, 73% with visceral metastasis, and 73% with ≥2 sites of metastases. Thirty (73%) patients had received 3 prior lines of therapy including AI (100%), tamoxifen (94%), fulvestrant (39%), and chemotherapy (100%) while the remaining had received <3 lines of prior therapy. The commonest Grade 3/4 adverse events were stomatitis (19%), hyperglycemia (new/worsening, 17%), fatigue (14.5%), nonneutropenic infections (14%), anemia (12%) and pneumonitis (7%). Everolimus dose reductions were required in 31% patients. There were 30% partial responses, 38% prolonged disease stabilizations and 32% disease progression as best responses to everolimus. The median progression-free survival was 22 weeks (5 months). CONCLUSIONS: Everolimus based treatment has meaningful activity in heavily pretreated patients with HR-positive MBC but is associated with considerable toxicity and requirement for dose adjustment.

Eribulin in heavily pretreated metastatic breast cancer: A tertiary care center experience from India.

INTRODUCTION: Heavily pretreated metastatic breast cancer (MBC) remains a major therapeutic challenge with limited treatment options this. Eribulin, an anti-microtubule agent, has been recently approved for this indication. There are sparse data from the Asian region for eribulin and merits exploration. MATERIALS AND METHODS: This was a single institution retrospective analysis of MBC patients treated with eribulin from 2013 to 2014. These patients had received at least 2 lines of prior therapy for metastatic disease. Patients received standard doses of eribulin and were monitored for toxicity and responses. RESULTS: Eighteen patients were included in this analysis. They had received a median of 6 lines of therapy previously (including adjuvant treatment) and had significant visceral involvement (median 3 organs). A median of 4 cycles of eribulin was delivered. There were no complete responses; partial responses were seen in 33% (6/18), stable disease status in 28% (5/18) patients, and progressive disease on eribulin in 39% (7/18) patients. The median progression-free survival was 15 weeks (3.5 months), and median overall survival was 27 weeks (6.2 months). Significant Grade 3/4 toxicities seen included peripheral neuropathy in 28% (5/18) and neutropenia in 28% (5/18) of patients while dose reductions were required in 22% (4/18) of patients. CONCLUSION: Eribulin offers a viable, well-tolerated regimen that provides meaningful clinical benefit in Indian patients with MBC.

Sunitinib in patients with imatinib-resistant gastrointestinal stromal tumor: A single center experience study.

AIM: The outcome of patients with advanced gastrointestinal stromal tumor (GIST) has improved with the use of imatinib. Despite high response rates with this drug resistance eventually develops in nearly all patients. We present an analysis of prospectively collected data on sunitinib efficacy and safety in patients with imatinib-resistant GIST. SUBJECTS AND METHODS: Between November 2006 and October 2007, patients with GIST were accrued in an approved sunitinib patient access protocol. Key eligibility criteria included tumor resistance to imatinib and/or patient intolerance to this drug. Patients received sunitinib at a starting dose of 50 mg once daily for 4 weeks in a 6 week cycle, with standardized dose modification titrated to toxicity. Patients were continued on sunitinib until disease progression or unacceptable toxicity. The endpoints were safety, overall survival (OS) and objective response rate (ORR). RESULTS: Fifteen patients, all of whom had imatinib resistance and none intolerance, with median age of 48 (26-69) years, were treated on the protocol. The most common sites of primary disease were small intestine (40%), stomach (26.7%) and retroperitoneal (26.7%). A median of 10 (1-47) cycles of sunitinib were delivered, 9 (60%) patients required dose reductions due to toxicity whereas dose delay of > 2 weeks was required in only one (6.7%) patient. There were no toxicity-related drug discontinuations. Hypothyroidism (n = 4; 26.7%) and hand-foot syndrome (n = 3; 20%) were the most common toxicities. There were no complete and 4 (26.7%) partial responses while prolonged disease stability was seen in 8 (53.3%) patients. At a median follow-up of 81 months in surviving patients, the median progression-free and overall survivals were 15.5 and 18.7 months, respectively. CONCLUSIONS: Sunitinib appears to be an effective and well-tolerated treatment for Indian patients with imatinib-resistant GIST with outcomes similar to that reported previously. Adverse effects can be reasonably well managed using a dose modification strategy.

Outcome of gestational trophoblastic neoplasia: experience from a tertiary cancer centre in India.

AIMS: Gestational trophoblastic neoplasms (GTN) comprise a spectrum of interrelated conditions originating from the placenta. With sensitive assays for human chorionic gonadotropin (ß-hCG) and current approaches to chemotherapy, most women with GTN can be cured with preservation of reproductive potential. The purpose of this analysis was to address the outcome of GTN from a developing country, as data are largely sparse from this region. MATERIALS AND METHODS: We undertook a retrospective review of GTN cases treated at our centre from 2001 to 2008. Patients of GTN were assigned to low-risk (score ≤ 6) or high-risk (score ≥ 7) categories as per the modified World Health Organization scoring system. The low-risk group was treated with single-agent methotrexate (MTX) and the high-risk group received the EMA/CO regimen. Salvage therapies were EMA/EP or BEP. Treatment was continued until serum ß-hCG values were normal for three consecutive chemotherapy cycles, after which the patients were kept on follow-up. RESULTS: In total, 70 GTN patients were treated at our institution during this period; 48 (68%) were low-risk and 22 (32%) were in the high-risk category. The median ß-hCG level was 50 000 IU/l. The lung was the most common site of metastasis, seen in 15 (21%) patients. Among 48 low-risk patients, 37 (77%) received chemotherapy, of whom 25 (68%) were treated with MTX and 24 (96%) achieved a complete response. Twelve low-risk patients (32%) received EMA/CO therapy; 10 (83%) achieved a complete response. The 22 high-risk patients received EMA/CO and of these 16 (73%) achieved a complete response, two (9%) progressed, two (9%) died of progressive disease and two (9%) were lost to follow-up. Grade 3/4 toxicities with MTX included mucositis in two (8%) and neutropenia in five (21%) patients. At a median follow-up of 16.6 months, overall survival in the low- and high-risk groups was 100 and 88.8%, respectively. CONCLUSION: Risk-stratified treatment of GTN was associated with acceptable toxicity and resulted in outcome that was comparable with international standards.

Management of febrile neutropenia in malignancy using the MASCC score and other factors: Feasibility and safety in routine clinical practice.

BACKGROUND: The current standards for empirical broad-spectrum intravenous antibiotic (AB) treatment, combined with hospitalization, are cautious and safe, but lead to over-treatment of a substantial group of patients. We need to validate parameters to identify these low-risk febrile-neutropenia (FN) patients, who could then be safely treated in an outpatient setting with minimal/no AB treatment. MATERIALS AND METHODS: A retrospective analysis for validation of a risk-assessment model in FN patients was done on a patient population from January 2007 to December 2008. Inclusion criteria were a histological diagnosis of malignancy, FN secondary to chemotherapy, absolute-neutrophil-count of ≤ 500/µl, axillary temperature of ≥ 38°C, and age ≥ 14 years. Other clinical and laboratory parameters were explored for risk stratification during the FN episodes. Receiver-operating characteristic curves were used to find the threshold value, an Chi-square analysis was done to find the association between the outcome and the parameters. RESULTS: A total of 178 FN episodes were documented; 22 in solid tumors and 156 in hematolymphoid malignancies. Culture positivity was documented in 59 episodes; peripheral blood was the most common source, with Escherichia coli being the most common organism identified. Risk stratification was done using the Multinational Association of Supportive Care in Cancer (MASCC) risk-index score. The association between the MASCC score and risk stratification could not be established (P = not significant) at a score of ≤ 21; however, it was found to be significant at a score of ≤ 18. The total number of complications was 23 (sepsis 22, mortality 23). Other factors found to be significantly associated with a high risk of complications in the univariate analysis were, mucositis (P = 0.03), maximum temperature ≥ 103°F (P = 0.01), tachycardia (P < 0.001), tachypnea (P = <0.001), age (P = 0.006), high dose of steroid (P < 0.001), total duration of fever (≥ 2.5 days (for which sensitivity (S) and specificity (Sp) were 87 and 81%, respectively), serum-creatinine (≥ 0.45 mg%, S = 100%, Sp = 97%), serum-bilirubin (≥ 0.5 mg/dl, S = 100%. Sp = 90%), requirement of second-line antibiotics (P = 0.02), intensive-care (P ≤ 0.001), ventilatory support (P < 0.001), and requirement of packed cell (PC) transfusion (P = 0.02). In the multivariate analysis, mucositis (P = 0.02), HD steroid use (P = 0.026), and PC requirement (0.026) were identified as independent variables. CONCLUSIONS: The MASCC risk-index score was found to be meaningful at a score of ≤ 18. Other clinical and laboratory parameters were found to have a strong association with risk stratification in cancer patients during FN episodes.

Comparison of isolates and antibiotic sensitivity pattern in pediatric and adult cancer patients; is it different?

BACKGROUND: Infection is a common cause of mortality and morbidity in cancer patients. Organisms are becoming resistant to antibiotics; age appears to be one of the factors responsible. We analyzed common organisms and their antibiotic sensitivity pattern in the correlation with age. METHODS: This is a single institutional, retrospective analysis of all culture positive adult and pediatric cancer patients from January 2007 to December 2007. For statistical analysis, Chi-square test for trend was used and P values were obtained. Of 1251 isolates, 262 were from children <12 years of age and 989 were from adolescents and adults (>12 years of age). Gram-negative organisms were predominant (64.95) while Gram-positive constituted 35.09% of isolates. RESULTS: The most common source in all age groups was peripheral-blood, accounting to 47.8% of all samples. The most common organisms in adults were Pseudomonas aeruginosa (15.3%) while in children it was coagulase negative Staphylococcus aureus (19.8%). Antibiotic sensitivity was different in both groups. In pediatric group higher sensitivity was seen for Cefoparazone-sulbactum, Cefipime, Amikacin, and Tobramycin. No resistance was found for Linezolid. CONCLUSIONS: The isolates in both children and adults were predominantly Gram-negative though children had proportionately higher Gram-positive organisms. High-dose cytarabine use, cotrimoxazole prophylaxis, and frequent use of central lines in children especially in hematological malignancies could explain this observation. Children harbor less antibiotic resistance than adults; Uncontrolled, cumulative exposure to antibiotics in our community with increasing age, age-related immune factors and variable bacterial flora in different wards might explain the higher antibiotic resistance in adults. Thus age is an important factor to be considered while deciding empirical antibiotic therapy.

Presentation, complications, and impact of concurrent malaria infection on anticancer therapy.

BACKGROUND: There is very limited data on the effects of malaria on on-going anticancer therapy. MATERIALS AND METHODS: We performed a retrospective analysis of adult solid tumor patients who contracted malaria while on active anticancer therapy. We noted their demographic profile, clinical course and the effects of malaria infection on their on-going anticancer therapy. Analysis was done with simple percentages. RESULTS: We analyzed 33 malarial episodes in 30 patients over 3 months. Plasmodium vivax was the most common type of infection (75%). Presenting symptoms included the typical triad of fever with chills and rigors. Malaria caused multiple complications, necessitating hospitalization in half of the patients and intensive care unit care in 1 of 8 patients. Common complications included thrombocytopenia (73%), anemia (67%), hyponatremia (66%), hepatic dysfunction (27%), and hypotension (12%). There were no deaths as a result of malaria. Malaria caused treatment delays with an average of 2.42 days per event. Plasmodium vivax caused more complications and therapy delays, average: 3.7 days per event, while non-vivax malaria caused an average of 0.5 days delay per event. There was a high level of resistance to chloroquine. CONCLUSION: Malaria is a significant problem in adult solid tumor patients, leading to multiple complications and therapy delays.
