Ten-year experience of the multidisciplinary Osteoncology Center.

PURPOSE: Bone metastases (BMs) are responsible for high morbidity in patients. A multidisciplinary approach involving a team of specialists offers an effective therapeutic strategy based on disease characteristics, medical history, and performance status. We evaluated the impact of our 10-year multidisciplinary experience on the management of patients with BM. METHODS: We retrospectively analyzed 2194 medical reports of 1628 patients referred to our Osteoncology Center from 2005 to 2015. Cases were discussed weekly by a multidisciplinary team. RESULTS: Eight hundred thirty-eight (38.2%) of the 2194 visits were requested because of a risk of complications from BM. Antiblastic treatment and bone-targeted therapy were modified in 709 (66.3%) and 309 (31%) of cases, respectively. Radiotherapy was scheduled in 220 (20%) of the 1099 patients for whom information was recorded. Patients completed the Brief Pain Inventory (BPI) during their first visit, 1296 (59.1%) reporting pain (median intensity 4), and 537 (41.4%) experiencing a level that interfered substantially with daily activities. New ortheses and/or antalgic therapy was prescribed accordingly. After 7 days, 208 (16%) patients were re-evaluated and a new BPI administered. A significant improvement in the worst (p < 0.0001) and current pain (p = 0.03) was seen, together with a favorable impact on daily activities (p = 0.02). Two thousand fifty-one patients completed an anonymous questionnaire on the quality of the service, the majority (69.4%) expressing high satisfaction. CONCLUSIONS: Our 10-year osteoncology experience confirms the importance of a multidisciplinary approach to optimize BM management. Further evaluations are needed in relation to quality of life, outcome, and costs.

Single bone metastasis from adenocarcinoma of the lacrimal gland: a case report.

Malignant tumors of the lacrimal gland are rare, and single bone metastases from lacrimal gland carcinoma are an exceptional event. We present the case of a 71-year-old man with a history of lumbar pain and left exophthalmos. Surgical resection of the lacrimal lesion and a bone biopsy gave a final histopathological diagnosis of primary ductal adenocarcinoma of the lacrimal gland with bone metastasis. The pathological tissue from both procedures was positive for androgen receptor expression. The patient underwent embolization and radiotherapy in association with total androgen blockade. After 20 months, the patient is still asymptomatic and has maintained the partial response at L1 with no progression to other sites. Our patient would appear to have a better prognosis and the disease a more indolent clinical course than the other cases of ductal adenocarcinoma of the lacrimal gland reported in the literature.

Case Report: Adult NTRK-Rearranged Spindle Cell Neoplasm: Early Tumor Shrinkage in a Case With Bone and Visceral Metastases Treated With Targeted Therapy.

BACKGROUND: NTRK (neurotrophic tyrosine receptor kinase)-rearranged spindle cell neoplasms are a new group of tumors included in the new 5th edition of the World Health Organization (WHO) classification of soft Tissue and Bone Sarcomas. These tumors are characterized by NTRK gene fusions and show a wide spectrum of histologies and clinical behavior. Several targeted therapies have recently been approved for tumors harboring NTRK fusions, including STS. CASE PRESENTATION: A 26-year-old male with advanced, pretreated NTRK rearranged spindle cell neoplasm and liver, lung and bone metastases was treated with larotrectinib on a continuous 28-day schedule, at a dose of 100 mg twice daily. An 18FDG-PET/CT scan performed after 7 days of treatment showed tumor shrinkage in both visceral and bone lesions. There was no drug-related toxicity. Subsequent evaluations confirmed continued tumor regression in disease sites. The patient is well and continues treatment. CONCLUSION: The clinical and radiological response of our patient with an uncommon TPM4 (exon 7)-NTRK1 (exon 12) gene fusion tumor treated with a first-generation TRK inhibitor could contribute to a better understanding of the biology of this new STS entity and help to improve patient management.

Multidisciplinary approach to the treatment of bone metastases: Osteo-Oncology Center, a new organizational model.

AIMS AND BACKGROUND: Bone metastases are responsible for high morbidity in cancer patients. The frequency of pain and other serious complications associated with such metastases depends on the site and type of lesions and preventive therapy. The present paper aims to inform the scientific community about a new organizational health care model specifically designed for patients with bone metastases, in the hope of stimulating the creation of similar initiatives whose goals are to decrease the high morbidity of this pathology, reduce the frequency of complications, limit psychophysical distress of patients, and improve quality of life. METHODS: In January 2005, an Osteo-Oncology Center was opened in our institute to provide multidisciplinary care (19 specialists involved) for patients with bone metastases, to train physicians, and to conduct research in the field. RESULTS: In its first three years of activity, 601 multidisciplinary team consultations were made and a total of 425 patients were seen. The most frequent primary tumor site was the lung in males and the breast in females. Upon presentation at the Center, 79% of patients reported experiencing a level of pain (median pain intensity, 3.69) that interfered with normal daily activities. An anonymous questionnaire was also completed on the quality of the service provided: 75% of patients were very satisfied, 23% were satisfied, 1% responded "I don't know", and only 1% expressed dissatisfaction. CONCLUSIONS: Our preliminary results confirm the usefulness of a multidisciplinary center for the management of patients with bone metastases, especially in terms of decreasing psychophysical suffering.
