Patients with salivary duct cancer (SDC) and HER2 overexpression could receive trastuzumab in combination with chemotherapy for metastatic disease. No standard treatment exists for patients with HER2-positive metastatic SDC after progression. We report an excellent patient response to second-line treatment with T-DM1 after progression on paclitaxel plus trastuzumab. Case Report: In June 2014, a 79-year-old male patient underwent right parotidectomy and ipsilateral radical neck dissection after the diagnosis of parotid carcinoma. Pathological staging demonstrated locally advanced disease with the involvement of 13 lymph nodes (levels I, II, III, and IV), with extracapsular extravasation. He underwent adjuvant radiotherapy ending in December 2014. A PET scan in March 2015 diagnosed recurrent and systemic disease, with bone lesions, neck lymph node involvement, and hepatic metastasis. The immunohistochemistry showed HER2 receptor overexpression (+3/+3). The patient received first-line trastuzumab plus paclitaxel beginning in April 2015. After 6 cycles, his response was confirmed by PET scan. In February 2016, he had symptoms of disease progression, and a PET scan revealed disease progression in the neck, bones, and liver. He started T-DM1 in April 2016. The neck skin lesions disappeared after 6 cycles, with low toxicity. PET scans performed every 3 months showed response in the liver and bone lesions. Conclusions: We report the case of a patient with SDC treated with T-DM1, with a very good response. Salivary carcinoma is a rare disease for which no randomized clinical trials are available. The maintenance of HER2 blockage might be important in this disease.

Introdução: Em Cuidados Paliativos, o grande objetivo do tratamento e a melhora da qualidade de vida dos pacientes. Esse construto engloba aspectos relacionados a sintomas, funcionalidade, bem-estar físico e social. Objetivo: Avaliar a qualidade de vida de pacientes internados em uma unidade de Cuidados Paliativos, demonstrando possíveis relações com os níveis sintomáticos. Método: Estudo transversal realizado com pacientes internados em uma unidade de cuidados paliativos que responderam ao questionário QLQ-C15-PAL da European Organization for Research and Treatment of Cancer em dezembro de 2013. Foram coletadas as variáveis sociais e registrados medicações e cuidados vigentes no tratamento. Resultados: Participaram do estudo 29 pacientes. A analise pelo teste U de Mann-Whitney evidenciou piores escores de dispneia associados a menor funcionalidade emocional (p=0,028); escores de funcionalidade física menores, níveis maiores de náuseas e vômitos, e de hiporexia associados a piores valores de performance status (p=0,047, p=0,038 e p=0,018, respectivamente). Alem disso, pacientes com acompanhante apresentaram tendencia a menores valores de escores de qualidade de vida (p=0,035). Conclusão: A avaliação de qualidade de vida e um aspecto importante da clinica diária em cuidados paliativos, sendo importante avaliar, além das cargas sintomáticas, a perspectiva do próprio paciente em relação a sua qualidade de vida.

Soft tissue sarcomas (STS) encompass a diverse family of neoplasms of mesenchymal origin, marked by significant heterogeneity in terms of physiopathology, molecular characterisation, natural history and response to different therapies. This review aims to summarise the current strategies for the management of patients with STS, including surgery, systemic treatments and radiation therapy, along with considerations applicable to the most frequent subtypes, as well as particularities associated with less common and specific histologies. It also provides insights into upcoming strategies to tackle this challenging group of diseases.

e17513 Background: Optimal treatment of synchronous tumors (ST) of the aerodigestive tract is debatable and care is often individualized. Our goal was to characterize patients with HNSCC and esophageal cancer (EC) ST and to establish prognostic factors that could aid therapeutic decision. Methods: In this retrospective observational study, we evaluated data from 1650 consecutive patients diagnosed with HNSCC from 2008 to 2016. Patients with ST of HNSCC and esophagus with an interval of ≤ 6 months between both diagnoses were included. Patients ≥ 6 months between both diagnoses, incomplete treatment information and presence of another tumor site were excluded. Results: 52 patients were eligible. Median age was 57 years (39-91). Most were male (98%), with smoking and drinking habits (98%) and ECOG 0-1 (73%). HNSCCs were mainly in oropharynx (54%) and locally advanced disease (LA, III-IVB) (88%). In contrast, EC was early stage (I-II, 62%), located in the thorax (94%) and squamous histology (96%). 14 (27%) had LA in both primaries. Most LA HNSCCs (85%) were treated with radiotherapy (RT) with a median dose of 70Gy (5-70Gy). 50% received platinum and taxane induction chemotherapy. 81% of initial EC received at least surgery, mucosectomy or RT (median 50.4Gy). Hospitalization due to toxicity occurred in 12 (23%) and 7 (14%) of HNSCC and EC treatments, respectively. 16 patients (31%) had no definitive treatment directed to EC, without apparent impact on survival. Median time to progression was 13.8 months, being HNSCC the most frequent site of progression/relapse (40%). Median survival was 23.9 months (IC 95% 9.2-38.6). Early HNSCC survival was comparable to LA HNSCC (17.3 vs. 23.9 mo, p = 0.98). In LA HNSCC, LA vs. initial EC carried a worse prognosis (16 vs. 36.3 mo, p = 0.008). Anemia, BMI, tobacco exposure had no impact on survival. Conclusions: The occurrence of EC and HNSCC ST leads to a dismal survival, even in patients with early stage HNSCC. The presentation of LA in both sites is particularly challenging and associated with worse prognosis. Given the rate of treatment-related toxicity in this population, cautious efforts should be employed when planning definitive treatment in ST pts.
