RESUMO

OBJECTIVES: To define current patterns of flexible (part-time) surgical training in Australasia, determine supply and demand for part-time positions, and identify work-related factors motivating interest in flexible training. DESIGN, SETTING AND PARTICIPANTS: All Royal Australasian College of Surgeons trainees (n = 1191) were surveyed in 2010. Questions assessed demographic characteristics and working patterns, interest in flexible training, work-related fatigue and work-life balance preferences. MAIN OUTCOME MEASURES: Interest in part-time training, and work-related factors motivating this interest. RESULTS: Of the 1191 trainees, 659 responded (response rate, 55.3%). Respondents were representative of all trainees in terms of specialty and sex. The median age of respondents was 32 2013s, and 187 (28.4%) were female. Most of the 659 respondents (627, 95.1%) were in full-time clinical training; only two (0.3%) were in part-time clinical training, and 30 (4.6%) were not in active clinical training. An interest in part-time training was reported by 208 respondents (31.6%; 54.3% of women v 25.9% of men; P < 0.001). Trainees expressing an interest in part-time training were more likely to report that fatigue impaired their performance at work and limited their social or family life, and that they had insufficient time in life for things outside surgical training, including study or research (P < 0.05). CONCLUSIONS: There is a striking mismatch between demand for flexible surgical training and the number of trainees currently in part-time training positions in Australia and New Zealand. Efforts are needed to facilitate part-time surgical training.

RESUMO

This report describes a young pregnant woman who presented to a rural emergency department with vaginal bleeding at 7 weeks of gestation. Initially, the patient was stable; however, within 8 h the patient deteriorated into fulminant septic shock. She required aggressive resuscitation and surgical management of a septic abortion. The patient's condition improved rapidly following surgical evacuation of the uterus with dilatation and curettage. She has had no long-term sequelae. Blood and tissue cultures returned positive for Clostridium septicum. To the best of our knowledge, this is the only reported case of survival from C septicum infection in a pregnant woman and highlights the importance of improved awareness and management of such infections by the medical community so that future cases can achieve similarly successful outcomes.

RESUMO

INTRODUCTION: : We sought to compare the rate of return of testosterone levels and sexual function in men with prostate cancer receiving longer acting, 3-month preparation of luteinizing hormone-releasing hormone agonist (L-LHRH-A) versus shorter acting, 1-month preparation of luteinizing hormone-releasing hormone agonist (S-LHRH-A). METHODS AND MATERIALS: : Men with low to intermediate risk localized prostate cancer were randomized to either L-LHRH-A (2-3 month duration LHRH-A) or S-LHRH-A (6-1 month duration LHRH-A) of androgen suppression therapy (AST) and prostate brachytherapy using iodine-125 radioisotopes. Serum total testosterone levels and PSA were recorded every 2 months for 2 years. RESULTS: : A planned target sample size of 100 was not achieved due to insufficient accrual. A total of 55 patients were randomized and 46 were used for analysis. The median time to recovery of testosterone to baseline levels (calculated from end of AST) was 8 and 4 months in the L-LHRH-A and S-LHRH-A arms, respectively (p = 0.268). The median time to testosterone recovery to lower limit of reference range was 4 and 2 months respectively (p = 0.087). INTERPRETATION: : This randomized study, which failed to reach accrual target, showed a trend towards more rapid recovery of testosterone levels using shorter acting LHRH-A. Another randomized study would be required to validate these findings. Currently, there is insufficient evidence to recommend the use of shorter acting LHRH-A as a means of providing more rapid recovery of testosterone levels.

RESUMO

BACKGROUND: The role of clinicopathologic characteristics of the recurrent tumor in determining survival in a cohort of patients with ipsilateral breast tumor recurrence (IBTR) was investigated. METHODS: Among 6020 women with pT1-T2, pN0-1, M0 treated with breast-conserving surgery from 1989 to 1999, 269 developed isolated IBTR. Ten-year Kaplan-Meier breast cancer-specific survival (BCSS) and overall survival (OS), calculated from date of IBTR, were analyzed according to clinicopathologic characteristics. RESULTS: Factors that were associated with diminished OS and BCSS on univariate analysis were: time to IBTR ≤48 months, lymphovascular invasion positive status, estrogen receptor (ER) negative status, high grade, clinical IBTR detection, biopsy alone, and close/positive margins (all P < .05). On multivariate analysis, time to IBTR ≤48 months (hazard ratio [HR], 1.87, P = .012), lymphovascular invasion positive status (HR, 2.46; P < .001), ER negative status (HR, 2.08; P = .013), high-grade recurrent disease (HR, 1.88; P = .013), and close/positive margins after surgery for IBTR (HR, 1.94; P = .013) retained significance for prediction of diminished OS. When stratified according to number of adverse prognostic features, 10-year OS was 70.4% in patients with 1 factor, 35.8% with 2 factors, and 19.9% with 3 or more factors (P < .001). CONCLUSIONS: Time to recurrence ≤48 months, lymphovascular invasion positive status, ER negative status, high-grade histology, and close/positive margins in association with the recurrent tumor are independent prognostic factors for survival after IBTR. The presence of 2 or more of these features at recurrence is significantly associated with poor OS. These criteria can be used to prognosticate and guide clinical decisions after recurrence.

RESUMO

PURPOSE: Ipsilateral breast tumor recurrence (IBTR) can occur in 5-20% of women with early-stage breast cancer treated with breast-conserving therapy. Two entities of IBTR have been described: true recurrence (TR), suggested to be regrowth of disease at the tumor bed, and new primary (NP), distinct from the index lesion in histology and location. This study compared survival outcomes between two patient cohorts classified clinically as having either TR or NP. METHODS AND MATERIALS: Between 1989 and 1999, 6,020 women were referred to the BC Cancer Agency with newly diagnosed pT1-2, N0-1, M0 invasive breast cancer, treated with breast-conserving surgery. Of these, 289 patients had pathologically confirmed IBTR. Retrospective analysis was performed, and a set of decision rules was applied to classify cases as TR or NP based on change in histology, grade, hormone receptor status, and tumor location. Of 289 patients, 129 (45%) were classified as having TR and 139 (48%) as having NP; 21 (7%) were unclassified. RESULTS: The distributions of age at diagnosis, age at recurrence, and histopathologic factors were similar in the TR and NP cohorts (all p > 0.05). The mean time to recurrence was shorter in TR patients than in NP patients (4.8 years vs. 6.3 years, p = 0.001). Treatment of the IBTR did not differ between the two groups. In the TR and NP cohorts, breast cancer-specific survival was 55.7% vs. 61.3% (p = 0.93), and overall survival was 43.7% vs. 54.8% (p = 0.53). CONCLUSIONS: Time to recurrence is significantly shorter in patients with IBTR classified as true recurrence compared to new primary. Non-statistically significant trends for less favorable survival were observed for patients with TR. Further investigation of the hypothesis that TR and NP tumors are distinct entities with different survival prognoses will require standardized pathology review and molecular analyses.

RESUMO

OBJECTIVE: To evaluate tolerability and compliance to a walking exercise program and its effect on fatigue during and after radical external beam radiation therapy (EBRT) for prostate cancer. METHODS: A total of 50 subjects with prostate cancer undergoing EBRT over 6 to 8 weeks were prospectively accrued to an exercise intervention group, matched for age and clinical characteristics to 30 subjects in a historical control group who underwent EBRT with no specific exercise intervention. Starting 1 week before EBRT, exercise participants performed moderate-intensity walking targeting 60% to 70% age-predicted maximum heart rate, at least 20 min/d, 3 d/wk over 12 weeks. The Brief Fatigue Inventory was administered at baseline, mid-EBRT (week 3-4), end-EBRT (week 6-8), and 6 months post-EBRT. RESULTS: Of 50, 42 (84%) of exercise participants completed the walking program. There were no cardiovascular complications, musculoskeletal injuries, or other adverse events. A total of 89% subjects reported "Good-Excellent" satisfaction during and up to 6 months post-EBRT. Fatigue in control subjects escalated from baseline to end-EBRT, remaining high at 6 months post-EBRT (P[r] = 0.03). In contrast, mean total fatigue scores in exercise subjects were stable from baseline up to 6 months post-EBRT (P = 0.52). Trends for higher fatigue interference with quality of life were observed in the control group as compared with the exercise group. CONCLUSIONS: Moderate-intensity walking exercise during radical EBRT is safe and feasible. The high convenience and satisfaction ratings, in conjunction with the observed fatigue trends, indicate that this activity has the potential to attenuate fatigue and improve quality of life for patients with localized prostate cancer undergoing curative therapy.

RESUMO

BACKGROUND: Adult tumors can be characterized by hypermethylation of CpG islands associated with 5'-upstream and coding regions of specific genes. This hypermethylation can also be part of the aging process. In contrast, much less is known about gene hypermethylation in childhood cancers, where methylation changes are not part of the aging process but likely represent developmental dysregulation. PAX3 is an important gene in muscle development and muscle-producing neoplasms such as rhabdomyosarcomas. PROCEDURES: We examined the methylation status of a PAX3 5'-CpG island in rhabdomyosarcoma subtypes and in normal fetal skeletal muscle. PAX3 methylation was analyzed in 15 embryonal rhabdomyosarcomas, 12 alveolar rhabdomyosarcomas, and in six normal skeletal muscle samples, using semi-quantitative PCR analysis of DNA digested with methyl-sensitive restriction enzymes. RESULTS: The CpG island in the upstream region of the human PAX3 gene was hypermethylated in the majority of ERMS examined (13 of 15 tumors, mean of 52% methylation), whereas most ARMS (9 of 12 tumors) and all normal muscle samples showed relative hypomethylation (both 18% mean methylation). Various CpG sites differ in contribution to overall PAX3 CpG island methylation, with methylation at a HaeII site being inversely correlated with PAX3 expression. CONCLUSIONS: PAX3 CpG island methylation appears to distinguish embryonal subtype of rhabdomyosarcoma from alveolar, and methylation at certain sites within this CpG island is inversely correlated with PAX3 expression. In addition to exemplifying developmental dysregulation, methylation of PAX3 has potential in the development of an epigenetic profile for the diagnosis of rhabdomyosarcoma.
