Consensus guidelines for the management of HR-positive HER2/neu negative early breast cancer in India, SAARC region and other LMIC by DELPHI survey method.

BACKGROUND: Precise prognostication is the key to optimum and effective treatment planning for early-stage hormone receptor (HR) positive, HER2/neu negative breast cancer patients. Differences in the breast cancer incidence and tumor anatomical features at diagnosis, pharmacogenomics data between Western and Indian women along with the vast diversity in the economic status and differences in insurance policies of these regions; suggest recommendations put forward for Western women might not be applicable to Indian/Asian women. Opinions from oncologists through a voting survey on various prognostic factors/tools to be considered for planning adjuvant therapy are consolidated in this report for the benefit of oncologists of the sub-continent, SAARC and Asia's LMIC (low and middle-income countries). METHODS: A three-phase DELPHI survey was conducted to collect opinions on prognostic factors considered for planning adjuvant therapy in early-stage HR+/HER2/neu negative breast cancer patients. A panel of 25 oncologists with expertise in breast cancer participated in the survey conducted in 2021. The experts provided opinions as 'agree' or disagree' or 'not sure' in phases-1 and 2 which were conducted virtually; in the final phase-3, all the panel experts met in person and concluded the survey. RESULTS: Opinions on 41 statements related to prognostic factors/tools and their implications in planning adjuvant endocrine/chemotherapy were collected. All the statements were supported by the latest data from the clinical trials (prospective/retrospective). The statements with opinions of consensus less than 66% were disseminated in phase-2, and later in phase-3 with supporting literature. In phase-3, all the opinions from panelists were consolidated and guidelines were framed. CONCLUSIONS: This consensus guideline will assist oncologists of India, SAARC and LMIC countries in informed clinical decision-making on adjuvant treatment in early HR+/HER2/neu negative breast cancer patients.

Indian Expert Opinion on Cancer Care during COVID-19 Pandemic.

Coronavirus pandemic has increased human disease burden, as well as economic distress globally. Being in an immunocompromised state, patients with cancer comprise an important at-risk population for novel coronavirus disease 2019 (COVID-19) infection. It is necessary to modify individualized clinical management for every cancer patient in the context of the ongoing COVID-19 pandemic. Simultaneously, additional safety precautions for the cancer care providers are mandatory. This review will provide general recommendations in the Indian context optimizing the same.

Practical Consensus Recommendations for Optimizing Risk versus Benefit of Chemotherapy in Patients with HR Positive Her2 Negative Early Breast Cancer in India.

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.

Genetic Counseling, Testing, and Management of HBOC in India: An Expert Consensus Document from Indian Society of Medical and Pediatric Oncology.

PURPOSE: Hereditary breast and ovarian cancer (HBOC) syndrome is primarily characterized by mutations in the BRCA1/2 genes. There are several barriers to the implementation of genetic testing and counseling in India that may affect clinical decisions. These consensus recommendations were therefore convened as a collaborative effort to improve testing and management of HBOC in India. DESIGN: Recommendations were developed by a multidisciplinary group of experts from the Indian Society of Medical and Pediatric Oncology and some invited experts on the basis of graded evidence from the literature and using a formal Delphi process to help reach consensus. PubMed and Google Scholar databases were searched to source relevant articles. RESULTS: This consensus statement provides practical insight into identifying patients who should undergo genetic counseling and testing on the basis of assessments of family and ancestry and personal history of HBOC. It discusses the need and significance of genetic counselors and medical professionals who have the necessary expertise in genetic counseling and testing. Recommendations elucidate requirements of pretest counseling, including discussions on genetic variants of uncertain significance and risk reduction options. The group of experts recommended single-site mutation testing in families with a known mutation and next-generation sequencing coupled with multiplex ligation probe amplification for the detection of large genomic rearrangements for unknown mutations. Recommendations for surgical and lifestyle-related risk reduction approaches and management using poly (ADP-ribose) polymerase inhibitors are also detailed. CONCLUSION: With rapid strides being made in the field of genetic testing/counseling in India, more oncologists are expected to include genetic testing/counseling as part of their clinical practice. These consensus recommendations are anticipated to help homogenize genetic testing and management of HBOC in India for improved patient care.

Management of Lymphomas: Consensus Document 2018 by an Indian Expert Group.

The clinical course of lymphoma depends on the indolent or aggressive nature of the disease. Hence, the optimal management of lymphoma needs a correct diagnosis and classification as B cell, T-cell or natural killer (NK)/T-cell as well as indolent or high-grade type lymphoma. The current consensus statement, developed by experts in the field across India, is intended to help healthcare professionals manage lymphomas in adults over 18 years of age. However, it should be noted that the information provided may not be appropriate to all patients and individual patient circumstances may dictate alternative approaches. The consensus statement discusses the diagnosis, staging and prognosis applicable to all subtypes of lymphoma, and detailed treatment regimens for specific entities of lymphoma including diffuse large B-cell lymphoma, Hodgkin's lymphoma, follicular lymphoma, T-cell lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, Burkitt's lymphoma, and anaplastic large cell lymphoma.

Randomized, double-blind, placebo-controlled phase II study of single-agent oral talactoferrin in patients with locally advanced or metastatic non-small-cell lung cancer that progressed after chemotherapy.

PURPOSE: To investigate the activity and safety of oral talactoferrin (TLF) in patients with stages IIIB to IV non-small-cell lung cancer (NSCLC) for whom one or two prior lines of systemic anticancer therapy had failed. PATIENTS AND METHODS: Patients (n = 100) were randomly assigned to receive either oral TLF (1.5 g in 15 mL phosphate-based buffer) or placebo (15 mL phosphate-based buffer) twice per day in addition to supportive care. Oral TLF or placebo was administered for a maximum of three 14-week cycles with dosing for 12 consecutive weeks followed by 2 weeks off. The primary objective was overall survival (OS) in the intent-to-treat (ITT) patient population. Secondary objectives included progression-free survival (PFS), disease control rate (DCR), and safety. RESULTS: TLF was associated with improvement in OS in the ITT patient population, meeting the protocol-specified level of significance of a one-tailed P = .05. Compared with the placebo group, median OS increased by 65% in the TLF group (3.7 to 6.1 months; hazard ratio, 0.68; 90% CI, 0.47 to 0.98; P = .04 with one-tailed log-rank test). Supportive trends were also observed for PFS and DCR. TLF was well tolerated and, generally, there were fewer adverse events (AEs) and grade ≥ 3 AEs reported in the TLF arm. AEs were consistent with those expected in late-stage NSCLC. CONCLUSION: TLF demonstrated an apparent improvement in OS in patients with stages IIIB to IV NSCLC for whom one or two prior lines of systemic anticancer therapy had failed and was well tolerated. These results should be confirmed in a global phase III trial.

A randomized, double-blind, placebo-controlled, phase II study of oral talactoferrin in combination with carboplatin and paclitaxel in previously untreated locally advanced or metastatic non-small cell lung cancer.

INTRODUCTION: The aim of the study is to investigate the activity and safety of oral talactoferrin (TLF) plus carboplatin and paclitaxel (C/P) in patients with previously untreated stage IIIB/IV non-small cell lung cancer. METHODS: Patients (n = 110) were randomly assigned to receive C/P plus either TLF (C/P/T) or placebo (C/P/P). The primary objective of this exploratory study was assessment of confirmed response rate (RR) in the prospectively defined evaluable population with a one-tailed p = 0.05. Secondary objectives included assessment of progression-free survival (PFS), duration of response, overall survival (OS), and safety. RESULTS: The trial met the primary end point of improvement in confirmed RR in the prospectively defined evaluable population. Compared with the C/P/P group, RR increased in the C/P/T group by 18% (29-47%; p = 0.05) and 15% (27-42%; p = 0.08) in the evaluable and intent-to-treat populations, respectively. Compared with the C/P/P group, the C/P/T group had a longer median PFS (4.2 versus 7.0 months), OS (8.5 versus 10.4 months), and duration of response (5.5 versus 7.6 months), although the differences were not statistically significant. Adverse events (AEs) were consistent with C/P therapy. There were fewer total AEs (472 versus 569; two-tailed p = 0.003) and grade 3/4 AEs (78 versus 105; p = 0.05) in the C/P/T group compared with the C/P/P group. CONCLUSION: TLF, in combination with C/P, demonstrated an apparent improvement in RR, PFS, and OS in patients with previously untreated stage IIIB/IV non-small cell lung cancer and appears to enhance activity without significant additional toxicity. These results need to be confirmed in a phase III trial.

The optimal use of granulocyte macrophage colony stimulating factor in radiation induced mucositis in head and neck squamous cell carcinoma.

OBJECTIVE: Evaluation of response of granulocyte macrophage colony stimulating factor (GM-CSF) on acute radiation toxicity profile in head and neck squamous cell carcinoma. METHODS AND MATERIALS: Thirty three patients with proven stage I or II head &neck carcinoma received conventional external beam radiation therapy. Out of these, six patients received postoperative adjuvant therapy while remaining 27 received definitive RT. Patients were given 100 mcg GM-CSF subcutaneously per day along with radiation after they developed grade 2 mucositis and /or grade 2 dysphagia and / or complained of moderate pain. GM-CSF was administered till there was a subjective relief or objective response. Patients were evaluated for oral ulceration, swallowing status, pain and weight loss. Response to the treatment and patient outcome was assessed. RESULTS: There was a decreased severity of mucositis and dysphagia in the evaluated patients. None of the patients suffered severe pain or required opioids. The mean weight loss was only 1.94%. Minimal side effects were experienced with GM-CSF. CONCLUSIONS: GM-CSF reduces the severity of acute side effects of radiation therapy thereby allowing completion of the treatment without interruption. Its remarkable response needs to be evaluated further in large randomized trials. The time of initiation and cessation of GM-CSF during radiation therapy and the required dose needs to be established.
