RESUMEN

PURPOSE: Despite proven benefits, few cancer patients exercise during chemotherapy. The American College of Sports Medicine's Exercise is Medicine® (EIM) initiative describes a model to integrate exercise into oncology care, based upon assessing patients' ability to exercise safely, advising on exercise benefits, and referring patients to exercise. We developed and tested a strategy to implement EIM in a community-based oncology clinic, to assess-advise-refer 20 patients undergoing chemotherapy to a 3-month online exercise class, and measured implementation outcomes. METHODS: Using a community-based provider participation in research (CBPPR) model, researchers and staff co-designed and tested a 4-level implementation strategy, with a goal of assessing-advising-referring 20 cancer patients to exercise. Surveys and interviews were conducted with 12 (100%) staff at baseline and post-implementation on acceptability/appropriateness/feasibility, perceptions of individual implementation roles, and organizational strengths/conditions. Data were analyzed using correlations, t-tests, and content analysis. RESULTS: The proposed strategy was revised in collaboration with staff who requested assistance for recruitment and data collection. EIM was successfully implemented with 41 (92%) patients assessed, 37 (90%) advised, and 22 (60%) referred to exercise classes. Barriers to implementation were staff shortages and time constraints; facilitators included research team supports. Staff's perceived organizational strengths were positively correlated with exercise promotion acceptability, appropriateness, and feasibility. There were no statistically significant changes in implementation outcomes (acceptability/appropriateness/feasibility) post-implementation. CONCLUSIONS: Using a collaborative model, EIM was successfully implemented in a community oncology clinic; however, the clinic required significant support from the research team. Adaptations to the EIM process may be required to improve implementation outcomes.

RESUMEN

RATIONALE: Breast cancer is the most common as well as one of the most devastating cancers among women in the United States. Prognosis is poor for patients with metastatic breast cancer, especially for patients with so-called "triple-negative" disease. The lack of effective therapies for metastatic triple-negative breast cancer outlines the need for novel and innovative treatment strategies. PATIENT CONCERNS: A 58-year-old underwent a mastectomy which revealed a recurrent triple-negative breast carcinoma. Afterward, she presented with a growing mass in her left axilla and chest wall. A computed tomography scan showed axillary and supraclavicular adenopathy, nodules in the left upper and lower lobe of the lungs, and 2 areas of disease in the liver. A bone scan showed lesions in the ribs. DIAGNOSIS: The patient was diagnosed with a recurrent metastatic triple-negative breast carcinoma that spread to the lung, liver, and bones. INTERVENTIONS: The patient was treated with metronomic chemotherapy, sequential chemotherapy regimens, and immunotherapy. OUTCOMES: The patient is now over 15 years out from her diagnosis of metastatic disease without any evidence of recurrent disease, likely due to the patient's treatment strategy which included sequential metronomic chemotherapy regimens and immunotherapy. LESSONS: Sequential metronomic chemotherapy regimens in combination with immunotherapy might be an effective treatment option for patients with metastatic triple-negative breast cancer. We hope that this case can provide some guidance for the treatment of metastatic triple-negative breast cancer and motivate research that can potentially lead to more cases of long-term survival for patients who develop this dismal disease.

RESUMEN

RATIONALE: Triple-negative breast cancer has a dismal prognosis, especially once it has spread to other organs, due to the lack of effective treatments available at this time. Finding an effective treatment for metastatic triple-negative breast cancer remains an unmet medical need. PATIENT CONCERNS: A 60-year-old woman was diagnosed with stage IIIC triple-negative breast cancer after undergoing a mastectomy. Her mastectomy was followed by adjuvant chemotherapy and radiation therapy. Approximately 1 year later, the patient presented with enlarging lymph nodes in her neck. A biopsy of a left supraclavicular lymph node was positive for recurrent disease. Positron emission tomography and computed tomography scans performed after the biopsy showed metabolic activity in the T6 vertebral body and the right level IIB lymph nodes. DIAGNOSES: The patient was diagnosed with recurrent metastatic triple-negative breast carcinoma with metastases to the bone and lymph nodes. INTERVENTIONS: The patient was treated with weekly metronomic chemotherapy, sequential chemotherapy regimens, and immunotherapy. OUTCOMES: The patient is now 68 years old and 7 years out from her diagnosis of metastatic disease. She achieved a complete response to her treatment and routine scans continue to show no evidence of recurrent disease. LESSONS: Utilizing sequential weekly metronomic chemotherapy regimens in combination with immunotherapy looks to be a promising treatment option for patients with metastatic triple-negative breast carcinoma. This is a second case where we were able to achieve long-term remission by using the above treatment strategy. These exciting results warrant further investigation of this treatment methodology. We hope that the treatment strategy described in this article can provide an outline for researchers and give patients with this disease more treatment options.

RESUMEN

Purpose: Patients with advanced non-small cell lung cancer (NSCLC) whose tumors harbor anaplastic lymphoma kinase (ALK) gene fusions benefit from treatment with ALK inhibitors (ALKi). Analysis of cell-free circulating tumor DNA (cfDNA) may provide a noninvasive way to identify ALK fusions and actionable resistance mechanisms without an invasive biopsy.Patients and Methods: The Guardant360 (G360; Guardant Health) deidentified database of NSCLC cases was queried to identify 88 consecutive patients with 96 plasma-detected ALK fusions. G360 is a clinical cfDNA next-generation sequencing (NGS) test that detects point mutations, select copy number gains, fusions, insertions, and deletions in plasma.Results: Identified fusion partners included EML4 (85.4%), STRN (6%), and KCNQ, KLC1, KIF5B, PPM1B, and TGF (totaling 8.3%). Forty-two ALK-positive patients had no history of targeted therapy (cohort 1), with tissue ALK molecular testing attempted in 21 (5 negative, 5 positive, and 11 tissue insufficient). Follow-up of 3 of the 5 tissue-negative patients showed responses to ALKi. Thirty-one patients were tested at known or presumed ALKi progression (cohort 2); 16 samples (53%) contained 1 to 3 ALK resistance mutations. In 13 patients, clinical status was unknown (cohort 3), and no resistance mutations or bypass pathways were identified. In 6 patients with known EGFR-activating mutations, an ALK fusion was identified on progression (cohort 4; 4 STRN, 1 EML4; one both STRN and EML4); five harbored EGFR T790M.Conclusions: In this cohort of cfDNA-detected ALK fusions, we demonstrate that comprehensive cfDNA NGS provides a noninvasive means of detecting targetable alterations and characterizing resistance mechanisms on progression.
