ABSTRACT
SUMMARY OBJECTIVE To evaluate the survival of patients with brain metastases treated surgically according to the potentially involved factors. METHODS 71 patients treated surgically were analyzed with the diagnosis of brain metastases during the period from January 2011 to November 2014, totaling 47 months of follow-up. The Kaplan-Meier curve method was used for survival analysis. Results We evaluated 71 patients with brain metastases treated surgically, 44 female and 27 male, mean age of 60.1 years. According to the Karnofsky scale, 44 patients were classified with Karnofsky greater than or equal to 70 and 27 patients with Karnofsky inferior to 70. Lung was the primary site most commonly found. Death occurred in twenty patients (28%), and lung tumors were responsible for the most deaths. Twelve patients had supra and infratentorial metastases, fifty-nine only had supratentorial lesions, and lesions were multiple in twenty-eight patients and single in forty-three. Thirty patients were also treated with chemotherapy, eighteen with chemotherapy and radiation therapy, while only three received just radiotherapy. Survival analysis by Kaplan-Meier curve showed no statistical significance regarding age, histological type, location, Karnofsky, chemotherapy, and radiotherapy. There was statistical significance regarding gender. CONCLUSION The factors analyzed did not change survival rates, except for gender. This fact may probably be explained due to the systemic and diffuse behavior of cancer.
RESUMO OBJETIVO Avaliar a sobrevivência de pacientes com metástases cerebrais tratados cirurgicamente de acordo com os fatores potencialmente envolvidos. Métodos 71 pacientes tratados cirurgicamente foram analisados com o diagnóstico de metástases cerebrais durante o período de janeiro de 2011 a novembro de 2014, totalizando 47 meses de seguimento. A curva de Kaplan-Meier foi utilizada para análise de sobrevivência. Resultados Avaliamos 71 pacientes com metástases cerebrais atendidas cirurgicamente, 44 do sexo feminino e 27 do sexo masculino, idade média de 60,1 anos. De acordo com a escala de Karnofsky, 44 pacientes foram classificados com Karnofsky maior ou igual a 70 e 27 pacientes com Karnofsky com menos de 70. O pulmão era o local mais comum. A morte ocorreu em 20 pacientes (28%) e os tumores pulmonares são responsáveis pela maioria das mortes. Doze pacientes apresentavam metástases supra e infratentoriais, 59 apresentavam apenas lesões supratentoriais, e as lesões eram múltiplas em 28 pacientes e isoladas em 43. Trinta pacientes também foram tratados com quimioterapia, 18 foram tratados com quimioterapia e radioterapia, enquanto que apenas três receberam apenas radioterapia. A análise de sobrevivência pela curva de Kaplan-Meier não mostrou significância estatística de acordo com a idade, tipo histológico, localização, Karnofsky, quimioterapia e radioterapia. Houve significância estatística em relação ao gênero. Conclusão Os fatores analisados não alteraram a sobrevivência, exceto o gênero. Este fato provavelmente pode ser explicado devido ao comportamento sistêmico e difuso do câncer.

BACKGROUND AND OBJECTIVES: Occult primary breast carcinoma is uncommon. Most reported series encompass a large periods of time with great variability in diagnostic and treatment approaches. The objective of the present study was to review the recent experience with this type of presentation of breast cancer in the University of Alabama at Birmingham. METHODS: Retrospective review of clinicopathological data of female patients presenting with axillary metastasis of adenocarcinoma with unknown primary and normal clinical and mammographic breast exam seen at UAB between 1985 and 1998. RESULTS: Ten patients were identified. Mean age was 56 years. Sixty per cent were white and postmenopausal. All patients had biopsy proven adenocarcinoma consistent with breast primary. All but one patient underwent an axillary dissection. Nine out of ten patients received some type of local treatment to the breast. Three of them underwent mastectomy and no invasive carcinoma was demonstrated in the surgical specimens. Six patients received radiation therapy to the breast. All patients received chemotherapy. With mean follow-up time of 48 months, two patients developed local recurrence to the axilla and four developed distant metastasis and eventually died. At last follow-up six patients are alive with no evidence of disease. CONCLUSIONS: In presence of axillary metastasis from an unknown breast primary, an extensive work-up evaluation is not necessary. An axillary dissection is recommended to provide prognostic indicators as well as local control. A breast conservation approach seems to be feasible without affect the local control and survival.

A prospective study of 149 patients suffering from adenocarcinoma of unknown primary site (ACUPS) of bone was carried out. The tumors are classified as 63 extraspinal, 67 spinal and 19 mixed involvement. Upon meticulous physical examination, Virchow's node was detected in 15 cases, rectal shelf in 11 cases and hepatomegaly in 44 cases. Blood chemistry showed elevation of alkaline phosphatase (> 3 sigma units) in 98 cases and chest roentgenogram showed pulmonary lesions in 23 cases. Treatment was surgery and radiotherapy in 64 and two cases respectively. In all of these patients histological findings of the biopsy or resection specimen had confirmed the diagnosis of adenocarcinoma. Among 124 evaluable patients, overall survival was analysed using Kaplan-Meier life table analysis. Survival rates at one, two and four months after diagnosis were 80.7, 60.5 and 25 per cent with a mean and median survival times of 90 and 77 days respectively. Statistical analysis was also performed to ascertain the prognostic importance of the following variables: age, gender, Virchow's node, rectal shelf, hepatomegaly, serum alkaline phosphatase, pulmonary lesion, and multiplicity and site of the osseous lesions. The presence of pulmonary lesion or hepatomegaly significantly produced unfavorable impact on the duration of survival (p = 0.0004 and 0.0150, respectively) while other remaining factors had not.
