ABSTRACT
OBJECTIVES: 1) To characterize the impact of multiple myeloma on the quality of life of patients treated in two public institutions in São Paulo State, Brazil, using a generic Short Form 36 Health Survey and a questionnaire specific for oncologic patients (QLQ-C30) upon diagnosis, after the clinical treatment, and at day +100 after autologous stem cell transplantation; 2) to evaluate whether autologous stem cell transplantation can improve the quality of life of our economically challenged population aside from providing a clinical benefit and disease control. METHODS: We evaluated 49 patients with multiple myeloma (a total of 70 interviews) using the two questionnaires. The scores upon diagnosis, post-treatment/pre-autologous stem cell transplantation, and at D+100 were compared using ANOVA (a comparison of the three groups), post hoc tests (two-by-two comparisons of the three groups), and paired t-tests (the same case at two different times). RESULTS: Of the included patients, 87.8 percent had a family budget under US $600 (economic class C, D, or E) per month. The generic Short Form 36 Health Survey questionnaire demonstrated that physical function, role-physical, and bodily pain indices were statistically different across all three groups, favoring the D+100 autologous stem cell transplantation group (ANOVA). The questionnaire specific for oncologic patients, the QLQ-C30 questionnaire, confirmed what had been demonstrated by the Short Form 36 Health Survey with respect to physical function and bodily pain, with improvements in role functioning, fatigue, and lack of appetite and constipation, favoring the D+100 autologous stem cell transplant group (ANOVA). The post hoc tests and paired t-tests confirmed a better outcome after autologous stem cell transplantation CONCLUSION: The questionnaire specific for cancer patients seems to be more informative than the generic Short Form 36 Health Survey questionnaire and reflects the real benefit of autologous stem cell transplantation in the quality of life of multiple myeloma patients in two public Brazilian institutions that provide assistance for economically challenged patients.

Este estudo objetivou detectar as alterações genéticas em pacientes com mieloma múltiplo (MM), usando o método de hibridação in situ por fluorescência em interfases (FISH interfásico). Para detectar as alterações numéricas foram usadas sondas multicentroméricas e para os rearranjos mais freqüentemente observados na doença foram utilizadas as sondas lócus específicas para IGH, P53, ciclina D1 e RB1. Foram estudados 34 pacientes com MM em estágio avançado, ainda que recém-diagnosticados, 97 por cento dos quais apresentaram anormalidades numéricas detectadas por FISH, sendo 75 por cento hiperdiplóides, 18 por cento hipodiplóides e 3 por cento tri/tetraplóides. Em relação às demais anormalidades, a deleção 13q foi encontrada em 30 por cento dos casos e o rearranjo IGH, em 25 por cento. Agrupando os pacientes com hipodiploidia e com deleção 13q14 (grupo desfavorável) e comparando-os com os demais (grupo não-desfavorável), houve tendência a pacientes jovens no grupo desfavorável (p = 0,06) e níveis de hemoglobina (Hb) significativamente mais baixos (< 8,5 g/dl, p = 0,03).
This study aimed to characterize genetic alterations by interphase multicentromeric FISH focusing on chromosomal numerical abnormalities and using some locus specific probes for the most frequent aberrations found in the disease, in a homogeneous cohort of 34 advanced stage, but recently diagnosed MM patients; 97 percent had numerical chromosomal abnormalities detected by FISH, being 75 percent hyperdiploid, 18 percent hypodiploid and 3 percent tri/tetraploid. Using locus specific probes, we found 13q deletion in 30 percent and IGH rearrangement in 25 percent of cases. Grouping hypodiploid patients together with del13q (unfavorable group) and comparing them to the remaining cases (non unfavorable group) we found a trend towards younger patients presenting more unfavorable abnormalities (p = 0.06) and significant lower hemoglobin level (Hb < 8.5 mg/dl, p = 0.03).
