Integrative Oncology Care of Symptoms of Anxiety and Depression in Adults With Cancer: SIO-ASCO Guideline Summary and Q&A

This SIO-ASCO guideline Q&A provides guidance on integrative oncology care of symptoms of anxiety and depression in adult patients with cancer

Integrative Oncology Care of Symptoms of Anxiety and Depression in Adults With Cancer: Society for Integrative Oncology-ASCO Guideline

PURPOSE

To provide evidence-based recommendations to health care providers on integrative approaches to managing anxiety and depression symptoms in adults living with cancer.

METHODS

The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, methodology, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2023. Outcomes of interest included anxiety or depression symptoms as measured by validated psychometric tools, and adverse events. Expert panel members used this evidence and informal consensus with the Guidelines into Decision Support methodology to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 110 relevant studies (30 systematic reviews and 80 randomized controlled trials) to inform the evidence base for this guideline.

RECOMMENDATIONS

Recommendations were made for mindfulness-based interventions (MBIs), yoga, relaxation, music therapy, reflexology, and aromatherapy (using inhalation) for treating symptoms of anxiety during active treatment; and MBIs, yoga, acupuncture, tai chi and/or qigong, and reflexology for treating anxiety symptoms after cancer treatment. For depression symptoms, MBIs, yoga, music therapy, relaxation, and reflexology were recommended during treatment, and MBIs, yoga, and tai chi and/or qigong were recommended post-treatment.

DISCUSSION

Issues of patient-health care provider communication, health disparities, comorbid medical conditions, cost implications, guideline implementation, provider training and credentialing, and quality assurance of natural health products are discussed. While several approaches such as MBIs and yoga appear effective, limitations of the evidence base including assessment of risk of bias, nonstandardization of therapies, lack of diversity in study samples, and lack of active control conditions as well as future research directions are discussed.Additional information is available at www.asco.org/survivorship-guidelines.

Immunotherapy and Biomarker Testing in Recurrent and Metastatic Head and Neck Cancers: ASCO Guideline

PURPOSE

To provide evidence-based recommendations for practicing physicians and other health care providers on immunotherapy and biomarker testing for head and neck cancers.

METHODS

ASCO convened an Expert Panel of medical oncology, surgical oncology, radiation oncology, radiology, pathology, and patient advocacy experts to conduct a literature search, including systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2000 through 2022. Outcomes of interest included survival, overall response, and locoregional control. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 28 relevant studies to inform the evidence base for this guideline.

RECOMMENDATIONS

When possible, evidence-based recommendations were developed to address biomarker testing, first-line treatment regimens based on programmed death ligand-1 scores, immunotherapy in platinum-refractory recurrent or metastatic head and neck squamous cell carcinoma, immunotherapy in nasopharyngeal carcinoma, and radiation therapy in combination with immunotherapy for treatment of local recurrence.Additional information is available at www.asco.org/head-neck-cancer-guidelines.

Integrative Medicine for Pain Management in Oncology: Society for Integrative Oncology-ASCO Guideline

PURPOSE

The aim of this joint guideline is to provide evidence-based recommendations to practicing physicians and other health care providers on integrative approaches to managing pain in patients with cancer.

METHODS

The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2021. Outcomes of interest included pain intensity, symptom relief, and adverse events. Expert panel members used this evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 227 relevant studies to inform the evidence base for this guideline.

RECOMMENDATIONS

Among adult patients, acupuncture should be recommended for aromatase inhibitor-related joint pain. Acupuncture or reflexology or acupressure may be recommended for general cancer pain or musculoskeletal pain. Hypnosis may be recommended to patients who experience procedural pain. Massage may be recommended to patients experiencing pain during palliative or hospice care. These recommendations are based on an intermediate level of evidence, benefit outweighing risk, and with moderate strength of recommendation. The quality of evidence for other mind-body interventions or natural products for pain is either low or inconclusive. There is insufficient or inconclusive evidence to make recommendations for pediatric patients. More research is needed to better characterize the role of integrative medicine interventions in the care of patients with cancer.Additional information is available at https://integrativeonc.org/practice-guidelines/guidelines and www.asco.org/survivorship-guidelines.

Biomarkers for Adjuvant Endocrine and Chemotherapy in Early-Stage Breast Cancer: ASCO Guideline Update

PURPOSE

To update recommendations on appropriate use of breast cancer biomarker assay results to guide adjuvant endocrine and chemotherapy decisions in early-stage breast cancer.

METHODS

An updated literature search identified randomized clinical trials and prospective-retrospective studies published from January 2016 to October 2021. Outcomes of interest included overall survival and disease-free or recurrence-free survival. Expert Panel members used informal consensus to develop evidence-based recommendations.

RESULTS

The search identified 24 studies informing the evidence base.

RECOMMENDATIONS

Clinicians may use Oncotype DX, MammaPrint, Breast Cancer Index (BCI), and EndoPredict to guide adjuvant endocrine and chemotherapy in patients who are postmenopausal or age > 50 years with early-stage estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative (ER+ and HER2-) breast cancer that is node-negative or with 1-3 positive nodes. Prosigna and BCI may be used in postmenopausal patients with node-negative ER+ and HER2- breast cancer. In premenopausal patients, clinicians may use Oncotype in patients with node-negative ER+ and HER2- breast cancer. Current data suggest that premenopausal patients with 1-3 positive nodes benefit from chemotherapy regardless of genomic assay result. There are no data on use of genomic tests to guide adjuvant chemotherapy in patients with ≥ 4 positive nodes. Ki67 combined with other parameters or immunohistochemistry 4 score may be used in postmenopausal patients without access to genomic tests to guide adjuvant therapy decisions. BCI may be offered to patients with 0-3 positive nodes who received 5 years of endocrine therapy without evidence of recurrence to guide decisions about extended endocrine therapy. None of the assays are recommended for treatment guidance in individuals with HER2-positive or triple-negative breast cancer. Treatment decisions should also consider disease stage, comorbidities, and patient preferences.Additional information is available at www.asco.org/breast-cancer-guidelines.

Enhancing Nigerian Healthcare Providers Competence in Breast Cancer Clinical Pathway Development using Blended Learning Approach

Purpose: Clinical pathways are a means of translating universal clinical guidelines into local protocols to inform clinical practice. This study aimed to evaluate the effectiveness of using a blended learning approach for providing instruction and building competency on the development of breast cancer clinical pathways, using the guidelines from the National Cancer Control Network (NCCN). Methods: A one-group pretest-post test design was used for this study. Participants included healthcare providers and students in Nigeria, who were recruited through social media and professional organizations. The intervention was an online course delivered through Google Classroom, followed by two-day workshops at three locations. Data collection involved pre and post-tests scores from the online course, self-reported evaluation, as well as objective grading of in-person group projects. Results: Over 400 individuals joined the online course while 90 participated in the in-person workshops. Most participants (259/408, 63%) had no prior experience with online education, with an average age of 27.46 (±9.25) years. Data analysis revealed significant increases in mean knowledge scores across all groups from pretest (M=12.76, SE = 0.60) to post test (M =17.25, SE =0.38) p<0.001. Self-reported evaluation showed higher scores regarding chemotherapy administration for blended learning participants. Objective competence scores in developing clinical pathways ranged from 63% to 87%, across three sites. Conclusion: Findings reveal that both an online course alongside in-person workshops can be effective strategies for improving the knowledge and competence respectively of healthcare professionals on clinical pathways development. Participants in the blended learning component demonstrated significantly greater improvement in self-reported confidence scores. We recommend further studies to compare the relative strengths and limitations of these strategies.

Outcomes of interest included survival, diagnostic accuracy, disease recurrence, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 293 relevant studies to inform the evidence base for this guideline. Six main clinical questions were addressed, which included subquestions on preoperative evaluations, surgical diagnostic and therapeutic procedures, appropriate radiotherapy techniques, the role of systemic therapy, and follow-up evaluations.

RECOMMENDATIONS

When possible, evidence-based recommendations were developed to address the diagnosis and appropriate preoperative evaluations for patients with a salivary gland malignancy, therapeutic procedures, and appropriate treatment options in various salivary gland histologies.Additional information is available at www.asco.org/head-neck-cancer-guidelines.

Radiation Therapy for Small-Cell Lung Cancer: ASCO Guideline Endorsement of an ASTRO Guideline

PURPOSE

The American Society for Radiation Oncology (ASTRO) produced an evidence-based guideline on radiation therapy (RT) for small-cell lung cancer (SCLC). Because of the relevance of this topic to ASCO membership, ASCO reviewed the guideline, applying a set of procedures and policies used to critically examine guidelines developed by other organizations.

METHODS

The ASTRO guideline on RT for SCLC was reviewed for developmental rigor by methodologists. Then, an ASCO Expert Panel reviewed the content and the recommendations.

RESULTS

The ASCO Expert Panel determined that the recommendations from ASTRO guideline on RT for SCLC, published in June 2020, are clear, thorough, and based upon the most relevant scientific evidence. ASCO endorsed ASTRO guideline on RT for SCLC with a few discussion points.

RECOMMENDATIONS

Recommendations addressed thoracic radiotherapy for limited-stage SCLC, role of stereotactic body radiotherapy in stage I or II node-negative SCLC, prophylactic cranial radiotherapy, and thoracic consolidation for extensive-stage SCLC. Additional information is available at www.asco.org/thoracic-cancer-guidelines .

Lung Cancer Surveillance After Definitive Curative-Intent Therapy: ASCO Guideline

PURPOSE

To provide evidence-based recommendations to practicing clinicians on radiographic imaging and biomarker surveillance strategies after definitive curative-intent therapy in patients with stage I-III non-small-cell lung cancer (NSCLC) and SCLC.

METHODS

ASCO convened an Expert Panel of medical oncology, thoracic surgery, radiation oncology, pulmonary, radiology, primary care, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2000 through 2019. Outcomes of interest included survival, disease-free or recurrence-free survival, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 14 relevant studies to inform the evidence base for this guideline.

RECOMMENDATIONS

Patients should undergo surveillance imaging for recurrence every 6 months for 2 years and then annually for detection of new primary lung cancers. Chest computed tomography imaging is the optimal imaging modality for surveillance. Fluorodeoxyglucose positron emission tomography/computed tomography imaging should not be used as a surveillance tool. Surveillance imaging may not be offered to patients who are clinically unsuitable for or unwilling to accept further treatment. Age should not preclude surveillance imaging. Circulating biomarkers should not be used as a surveillance strategy for detection of recurrence. Brain magnetic resonance imaging should not be used for routine surveillance in stage I-III NSCLC but may be used every 3 months for the first year and every 6 months for the second year in patients with stage I-III small-cell lung cancer who have undergone curative-intent treatment.

Oncology Guidelines Usage in a Low- and Middle-Income Country

PURPOSE

There is a paucity of data about current usage of oncology guidelines in low- and middle-income countries (LMICs), specifically in terms of the availability and quality of those guidelines. Our objective was to determine usage of oncology guidelines and the barriers and facilitators to their usage among radiation oncologists in LMICs.

METHODS

An online cross-sectional survey was conducted among practicing radiation oncologists in Nigeria via e-mail and the social media database of the Association of Radiation and Clinical Oncologists of Nigeria. In addition, paper questionnaires were administered at regional clinical meetings.

RESULTS

The survey response rate was 53.4% in a sample of 101 radiation oncologists from the database. Sixty-nine percent of respondents were consultants and 30% were residents. Approximately 43% had < 5 years' experience. All of the respondents were involved in administering chemotherapy during the treatment of patients with cancer, whereas approximately half were involved in diagnosing cancer. Ninety-three percent reported using guidelines in treating patients, the top two guidelines being those from the National Comprehensive Cancer Network (90%) and the American Society of Clinical Oncology (50%). The two major barriers to guideline usage were that facilities were inadequate for proper guideline implementation and that the information in guidelines were too complex to understand. Potential facilitators included providing adequate facilities, developing local guidelines, and increasing awareness of guideline usage.

CONCLUSION

Our study shows that clinicians involved in the treatment of patients with cancer in LMICs are aware of cancer treatment guidelines. However, implementation of these guidelines hinders their usage because the facilities are inadequate, guidelines are not applicable to the local setting, and the information in the guidelines is too complex.

Role of Patient and Disease Factors in Adjuvant Systemic Therapy Decision Making for Early-Stage, Operable Breast Cancer: Update of the ASCO Endorsement of the Cancer Care Ontario Guideline

PURPOSE

To update the American Society of Clinical Oncology endorsement of the Cancer Care Ontario recommendations on the Role of Patient and Disease Factors in Adjuvant Systemic Therapy Decision Making for Early-Stage, Operable Breast Cancer.

METHODS

Two phase III trials—the Trial Assigning Individualized Options for Treatment (TAILORx) in women with hormone receptor–positive, node-negative tumors and the Microarray in Node-Negative and 1 to 3 Positive Lymph Node Disease May Avoid Chemotherapy (MINDACT) trial—provided the evidence for this update.

UPDATED RECOMMENDATIONS

Shared decision making between clinicians and patients is appropriate for adjuvant systemic therapy for breast cancer. For patients older than age 50 years and whose tumors have Onco type DX recurrence scores less than 26, and for patients age 50 years or younger whose tumors have Onco type DX recurrence scores less than 16, there is little to no benefit from chemotherapy. Clinicians may offer endocrine therapy alone for these patients. For patients age 50 years or younger with recurrence scores of 16 to 25, clinicians may offer chemoendocrine therapy. Patients with recurrence scores greater than 30 should be considered candidates for chemoendocrine therapy. Based on informal consensus, the Panel recommends that oncologists may offer chemoendocrine therapy to patients with Onco type DX scores of 26 to 30. The MammaPrint assay could be used to guide decisions on withholding adjuvant systemic chemotherapy in patients with hormone receptor–positive lymph node–negative breast cancer and in select patients with lymph node–positive cancers. In both patients with node-positive and node-negative disease, evidence of clinical utility of the MammaPrint assay was only apparent in those determined to be at high clinical risk; the Panel thus did not recommend use of MammaPrint assay in patients determined to be at low clinical risk. Remaining recommendations from the 2016 ASCO guideline endorsement are unchanged. Additional information is available at www.asco.org/breast-cancer-guidelines .

Use of Biomarkers to Guide Decisions on Adjuvant Systemic Therapy for Women With Early-Stage Invasive Breast Cancer: ASCO Clinical Practice Guideline Update—Integration of Results From TAILORx

PURPOSE

This focused update addresses the use of Onco type DX in guiding decisions on the use of adjuvant systemic therapy.

METHODS

ASCO uses a signals approach to facilitate guideline updating. For this focused update, the publication of the Trial Assigning Individualized Options for Treatment (TAILORx) evaluating noninferiority of endocrine therapy alone versus chemoendocrine therapy for invasive disease–free survival in women with Onco type DX scores provided a signal. An expert panel reviewed the results of TAILORx along with other published literature on the Onco type DX assay to assess for evidence of clinical utility.

UPDATED RECOMMENDATIONS

For patients with hormone receptor–positive, axillary node–negative breast cancer whose tumors have Onco type DX recurrence scores of less than 26, there is little to no benefit from chemotherapy, especially for patients older than age 50 years. Clinicians may recommend endocrine therapy alone for women older than age 50 years. For patients 50 years of age or younger with recurrence scores of 16 to 25, clinicians may offer chemoendocrine therapy. Patients with recurrence scores greater than 30 should be considered candidates for chemoendocrine therapy. Based on informal consensus, the panel recommends that oncologists may offer chemoendocrine therapy to these patients with recurrence scores of 26 to 30.

Role of Treatment Deintensification in the Management of p16+ Oropharyngeal Cancer: ASCO Provisional Clinical Opinion

PURPOSE

An ASCO provisional clinical opinion offers timely clinical direction to ASCO’s membership after publication or presentation of potentially practice-changing data from major studies. This provisional clinical opinion addresses the role of treatment deintensification in the management of p16+ oropharyngeal cancer (OPC).

CLINICAL CONTEXT

For patients with p16+ OPC, current treatment approaches are well established. In the good-prognosis subset of nonsmoking p16+ patients with early-stage disease, these treatments have been highly successful, albeit with significant associated acute and late toxicity. Deintensification of surgical, radiation, and medical treatment in an effort to reduce toxicity while preserving high survival rates is an appropriate therapeutic objective currently being explored in patients who are experiencing the best treatment results. However, careful delineation of this good-risk subset is essential. While the current eighth edition of the American Joint Committee on Cancer staging system is prognostically robust, it should not be interpreted as reason to alter therapeutic decisions or justify treatment deintensification. The development of transoral surgical techniques and the adoption of intensity-modulated radiation therapy planning have been transformative in disease management and suggest potentially beneficial approaches. Recent advances in systemic treatments have been notable. The optimal integration and modification of these modalities to ameliorate toxicity has not been defined and remains an important focus of current investigation.

PROVISIONAL CLINICAL OPINION

The hypothesis that de-escalation of treatment intensity for patients with p16+ OPC can reduce long-term toxicity without compromising survival is compelling and necessitates careful study and the analysis of well-designed clinical trials before changing current treatment standards. Treatment deintensification for these patients should only be undertaken in a clinical trial. Additional information is available at www.asco.org/head-neck-cancer-guidelines .

Using blended learning to improve education on clinical pathways for breast cancer management in Nigeria: Preliminary results

10539

Background: Most Nigerian clinicians lack adequate skills and resources in screening, diagnosis, and managing women with breast cancer. The absence of locally-sensitive clinical pathways in hospitals in Abia State impact patient outcomes and clinicians job satisfaction. Blended learning (BL), a combination of online and face-to-face teaching methods, has been used in other settings to improve the competencies of clinicians. Research seeks to develop and evaluate a BL course that will train clinicians in Abia State on using NCCN breast cancer management guidelines, and to develop and implement locally-sensitive clinical pathways. Methods: The course is divided into four online modules delivered via Google Classroom and a workshop module to be delivered in 3 cities. Course evaluation involves an objective-focused method, following a mixed-methods design. Data collection includes pre-and-post-tests, course evaluation and focus group discussions. Data analysis involved descriptive statistics and t-test. Comments deductively analyzed to identify common themes. A sample size of 107 individuals is required to identify a moderate effect size for the BL course. Results: Forty-three participants (physicians=15, Nurses=28) have been recruited for cohort 1, with average age of 44 (±9.9) years. Most participants have never taken an online class (65%) but use mobile phones (60%) to access the course. With a maximum of 20 points in each test, there is a pattern of improvement in the post-tests performance compared with the pre-tests. Table shows mean scores. Most participants have expressed satisfaction with the course. Conclusions: Results show improvement in learning. More participants are being recruited. The workshops will hold at after the online modules.[Table: see text]

Treatment of Multiple Myeloma: ASCO and CCO Joint Clinical Practice Guideline

PURPOSE

To provide evidence-based recommendations on the treatment of multiple myeloma to practicing physicians and others.

METHODS

ASCO and Cancer Care Ontario convened an Expert Panel of medical oncology, surgery, radiation oncology, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and some phase II studies published from 2005 through 2018. Outcomes of interest included survival, progression-free survival, response rate, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 124 relevant studies to inform the evidence base for this guideline.

RECOMMENDATIONS

Evidence-based recommendations were developed for patients with multiple myeloma who are transplantation eligible and those who are ineligible and for patients with relapsed or refractory disease.

Management of the Neck in Squamous Cell Carcinoma of the Oral Cavity and Oropharynx: ASCO Clinical Practice Guideline

PURPOSE

The aim of the current work is to provide evidence-based recommendations to practicing physicians and others on the management of the neck in patients with squamous cell carcinoma of the oral cavity and oropharynx.

METHODS

ASCO convened an Expert Panel of medical oncology, surgery, radiation oncology, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 1990 through 2018. Outcomes of interest included survival, regional disease control, neck recurrence, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations.

RESULTS

The literature search identified 124 relevant studies to inform the evidence base for this guideline. Six clinical scenarios were devised; three for oral cavity cancer and three for oropharynx cancer, and recommendations were generated for each one.

RECOMMENDATIONS

For oral cavity cancers, clinical scenarios focused on the indications for and the hallmarks of a high-quality neck dissection, indications for postoperative radiotherapy or chemoradiotherapy, and whether radiotherapy alone is sufficient elective treatment of an undissected neck compared with high-quality neck dissection. For oropharynx cancers, clinical scenarios focused on hallmarks of a high-quality neck dissection, factors that would favor operative versus nonoperative primary management, and clarifying criteria for an incomplete response to definitive chemoradiation for which salvage neck dissection would be recommended. Consensus was reached and recommendations were made for all six clinical scenarios. Additional information is available at www.asco.org/head-neck-cancer-guidelines .

Initial Diagnostic Work-Up of Acute Leukemia: ASCO Clinical Practice Guideline Endorsement of the College of American Pathologists and American Society of Hematology Guideline

PURPOSE

The College of American Pathologists (CAP) and the American Society of Hematology (ASH) developed an evidence-based guideline on the initial diagnostic work-up of acute leukemia (AL). Because of the relevance of this topic to the ASCO membership, ASCO reviewed the guideline and applied a set of procedures and policies for endorsing clinical practice guidelines that have been developed by other professional organizations.

METHODS

The CAP-ASH guideline on initial diagnostic work-up of AL was reviewed for developmental rigor by methodologists. Then, an ASCO Endorsement Expert Panel updated the literature search and reviewed the content and recommendations.

RESULTS

The ASCO Expert Panel determined that the recommendations from the guideline, published in 2016, are clear, thorough, and based on the most relevant scientific evidence. ASCO fully endorsed the CAP-ASH guideline on initial diagnostic work-up of AL and included some discussion points according to clinical practice and updated literature.

CONCLUSION

Twenty-seven guideline statements were reviewed. Some discussion points were included to better assess CNS involvement in leukemia and to provide novel insights into molecular diagnosis and potential markers for risk stratification and target therapy. These discussions are categorized into four sections: (1) initial diagnosis focusing on basic diagnostics and determination of risk parameters, (2) molecular markers and minimal residual disease detection, (3) context of referral to another institution with expertise in the management of AL, and (4) reporting and record keeping for better outlining and follow-up discussion.

Role of Bone-Modifying Agents in Multiple Myeloma: American Society of Clinical Oncology Clinical Practice Guideline Update

Purpose To update guideline recommendations on the role of bone-modifying agents in multiple myeloma. Methods An update panel conducted a targeted systematic literature review by searching PubMed and the Cochrane Library for randomized controlled trials, systematic reviews, meta-analyses, clinical practice guidelines, and observational studies. Results Thirty-five relevant studies were identified, and updated evidence supports the current recommendations. Recommendations For patients with active symptomatic multiple myeloma that requires systemic therapy with or without evidence of lytic destruction of bone or compression fracture of the spine from osteopenia on plain radiograph(s) or other imaging studies, intravenous administration of pamidronate 90 mg over at least 2 hours or zoledronic acid 4 mg over at least 15 minutes every 3 to 4 weeks is recommended. Denosumab has shown to be noninferior to zoledronic acid for the prevention of skeletal-related events and provides an alternative. Fewer adverse events related to renal toxicity have been noted with denosumab compared with zoledronic acid and may be preferred in this setting. The update panel recommends that clinicians consider reducing the initial pamidronate dose in patients with preexisting renal impairment. Zoledronic acid has not been studied in patients with severe renal impairment and is not recommended in this setting. The update panel suggests that bone-modifying treatment continue for up to 2 years. Less frequent dosing has been evaluated and should be considered in patients with responsive or stable disease. Continuous use is at the discretion of the treating physician and the risk of ongoing skeletal morbidity. Retreatment should be initiated at the time of disease relapse. The update panel discusses measures regarding osteonecrosis of the jaw. Additional information is available at www.asco.org/hematologic-malignancies-guidelines and www.asco.org/guidelineswiki .

Treatment of Malignant Pleural Mesothelioma: American Society of Clinical Oncology Clinical Practice Guideline

Purpose To provide evidence-based recommendations to practicing physicians and others on the management of malignant pleural mesothelioma. Methods ASCO convened an Expert Panel of medical oncology, thoracic surgery, radiation oncology, pulmonary, pathology, imaging, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 1990 through 2017. Outcomes of interest included survival, disease-free or recurrence-free survival, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. Results The literature search identified 222 relevant studies to inform the evidence base for this guideline. Recommendations Evidence-based recommendations were developed for diagnosis, staging, chemotherapy, surgical cytoreduction, radiation therapy, and multimodality therapy in patients with malignant pleural mesothelioma.
