Prognostic factors of primary resected retroperitoneal soft tissue sarcoma: Analysis from a single asian tertiary center and external validation of gronchi's nomogram.

BACKGROUND: Surgery is the potentially curative treatment for retroperitoneal sarcoma (RS), but complete resectability is frequently a challenge. This study aimed to characterize the clinical features, prognostic factors and treatment outcomes. METHODS: A cohort of 144 patients with RS was surveyed retrospectively from January 1st, 2000 to July 30th, 2011. The prognostic influence of clinicopathological characteristics as well as treatments on local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and overall survival (OS), were examined by univariate and multivariate analyses. A histology-specific nomogram developed by Gronchi et al was used for validation. RESULTS: Liposarcoma, leiomyosarcoma, and malignant peripheral sheath tumor (MPNST) were the most common histologies (70%). Multivariate analysis revealed FNCLCC tumor grade was the most significant prognostic factor for OS (P = 0.001) and DMFS (P < 0.001) and complete resection was the only significant prognostic factor for LRFS (P = 0.043). Incomplete resection of grade 3 tumor was significantly associated with a worse OS. Despite some differences in characteristics between our patients and Gronchi's cohort, external validation of Gronchi's nomogram demonstrated excellent concordance in predicting survival. CONCLUSIONS: Our study demonstrated tumor grade and surgical margins had significant prognostic influence and the Gronchi's nomogram has an excellent applicability in predicting survival of STS patients.

The impact of pain control on physical and psychiatric functions of cancer patients: a nation-wide survey in Taiwan.

OBJECTIVE: To investigate the prevalence of pain in cancer patients at different disease statuses, the impact of pain on physical and psychiatric functions of patients and the satisfaction of pain control of patients at outpatient clinic department in Taiwan. METHODS: Short form of the Brief Pain Inventory was used as the outcome questionnaire. Unselected patients of different cancers and different disease statuses at outpatient clinic department were included. The impacts of their current pain control on physical function, psychiatric function and the satisfaction of doctors were evaluated. Logistic regression analyses were performed to evaluate whether the interference scale performed identically in the different analgesic ladders. The dependent variables were satisfaction toward physician and treatment. RESULTS: A total of 14 sites enrolled 2075 patients in the study. One thousand and fifty-one patients reported pain within the last 1 week. In patients whose diseases deteriorated, >60% of them need analgesics for pain control. Pain influenced physical and psychiatric functions of patients, especially in the deteriorated status. More than 80% of patients were satisfied about current pain control, satisfaction rate related to disease status, pain intensities and treatments for pain. CONCLUSION: Our study found that different cancers at different statuses had pain at variable severity. Pain can influence physical and psychological functions significantly. More than 75% of subjects reported satisfaction over physician and pain management in outpatient clinic department patients with cancer pain in Taiwan.

Host factors do not influence the colonization or infection by fluconazole resistant Candida species in hospitalized patients.

Nosocomial yeast infections have significantly increased during the past two decades in industrialized countries, including Taiwan. This has been associated with the emergence of resistance to fluconazole and other antifungal drugs. The medical records of 88 patients, colonized or infected with Candida species, from nine of the 22 hospitals that provided clinical isolates to the Taiwan Surveillance of Antimicrobial Resistance of Yeasts (TSARY) program in 1999 were reviewed. A total of 35 patients contributed fluconazole resistant strains [minimum inhibitory concentrations (MICs) > or = 64 mg/l], while the remaining 53 patients contributed susceptible ones (MICs < or = 8 mg/l). Fluconazole resistance was more frequent among isolates of Candida tropicalis (46.5%) than either C. albicans (36.8%) or C. glabrata (30.8%). There was no significant difference in demographic characteristics or underlying diseases among patients contributing strains different in drug susceptibility.
