Neoplastic pulmonary lymphangitis (NPL) is the intrapulmonary spread of metastatic neoplasm via lymphatic tissue, and accounts for 6-8% of lung metastasis: symptom distress has great impact on quality of life

A linfangite pulmonar neoplásica (LPN) é a disseminação intrapulmonar de células neoplásicas metastáticas via vasos linfáticos, englobando 6 a 8% das metástases pulmonares. Seu desconforto sintomático tem grande impacto na qualidade de vida (QdV) e seu prognóstico é muito reservado. Nosso objetivo foi avaliar os aspectos clínicos, o tratamento, a QdV e a sobrevida em LPN, em um estudo prospectivo. O seguimento mediano foi de 32 dias; 79% dos pacientes foram seguidos por menos de 6 meses, devido a evolução desfavorável e óbito. A idade mediana dos pacientes foi de 60,5 anos; 65% eram mulheres. A maioria dos sítios primários de neoplasia foram pulmão e mama (88%). A QdV estava comprometida, mas podiam ter algum benefício terapêutico, especialmente com corticosteróides, e a quimioterapia melhorou a sobrevida. Algumas variáveis foram estatisticamente significantes para predizer o status de sobrevida em um mês: Karnofsky performance scale (KPS)>=60%, hemoglobina(Hb)>=10 g/dL, LPN unilateral, PO2>=60 mmHg, tratamento oncológico sistêmico e sem necessidade de ventilação assistida não-invasiva. Preditores significantes de maior sobrevida mediana foram: KPS>=60%, SpO2>=90%, Hb>=10 g/dL, sem hipoxemia (PO2>=60 mmHg), sem necessidade de oxigenioterapia, tratamento com opióide fraco, tratamento oncológico sistêmico e ausência de ventilação assistida. O tratamento sintomático deve ser ativo, oferecendo melhor QdV aos pacientes e familiares e o tratamento etiológico é importante. As avaliações de QdV facilitam a relação médico-paciente, além da informação prognostica ser crucial para ajudar na definição e planejamento terapêuticos, uma vez que análises de parâmetros de custo-benefício e metas realistas são essenciais para cuidados oncológicos paliativos de boa qualidade, especialmente em síndromes com prognóstico reservado, tal como a LPN.Our objective was to evaluate clinical aspects, treatment, QoL, and survival, in NPL in a prospective study. Median follow-up was of 32 days; 79% percent of patients were followed for less than 6 months, due to bad outcome. Median age was 60.5 years; 65% were female. Most primary tumor sites were lung and breast cancers (88%). QoL was compromised, but could have treatment benefit, especially with corticosteroids, and chemotherapy improved survival. Some variables were statistically significant for predicting survival status in one month, such as: Karnofsky performance scale (KPS)>=60%, hemoglobin>=10 g/dL, unilateral NPL, PO2>=60 mmHg, oncological systemic treatment, and no need for noninvasive assisted ventilation. Significant predictors of longer median survival were: KPS>=60%, SpO2>=90%, hemoglobin>=10 g/dL, without hypoxemia (PO2>=60 mmHg), no need for oxygen therapy, weak opioid treatment, systemic oncological treatment, and absence of assisted ventilation. Symptomatic treatment must be active, offering better QoL to patients and their families, and etiological treatment is important. QoL evaluation facilitates patient-physician relationship, and prognostic information is crucial to help in defining treatment plan, since cost-benefit parameter analysis and realistic goals are essential in good-quality palliative cancer care, especially for syndromes with poor prognosis, such as NPL

Synchronous thyroid and colon metastases from epidermoid carcinoma of the lung: case report

CONTEXT: Non-small cell lung cancer (NSCLC) progresses to distant metastases in most cases. The most frequent sites for distant metastases are the bones, central nervous system, adrenal glands and liver. Dissemination to the skin, myocardium, thyroid gland and intestine may occur, but is rare. CASE REPORT: We describe a case of squamous cell carcinoma in the lungs, with metastases in the colon and thyroid, in a 66-year-old female patient. The lesion was unresectable and chemotherapy was started. The patient evolved with intestinal subocclusion, and colonoscopy showed the presence of a polyp. Biopsy and immunohistochemical analysis on the polyp showed that it was compatible with squamous cell carcinoma of pulmonary origin. At a follow-up consultation, the patient presented a thyroid nodule. A aspiration biopsy and cellblock immunohistochemistry confirmed the squamous cell carcinoma of pulmonary origin. After third-line chemotherapy, the patient progressed with acute obstructive abdomen due to a retroperitoneal mass. She underwent exploratory laparotomy and died due to surgical complications. Metastases to the thyroid and colon are rarely reported in cases of epidermoid carcinoma of the lungs. Gastrointestinal involvement in pulmonary metastases may affect the stomach, small intestine and colon, and cases of bleeding and perforation have already been reported. Although richly vascularized, the thyroid is an infrequent site for metastases. Such sites reflect poor prognoses for the clinical evolution. We did not find any previous reports in the literature, on lung cancer with metastases concomitantly in the colon and thyroid, in a single patient
