Longer duration of symptoms at the time of presentation is not associated with worse survival in primary bone sarcoma.

Aims: The primary aim of this study was to determine the effect of the duration of symptoms (DOS) prior to diagnosis on the overall survival in patients with a primary bone sarcoma. Patients and Methods: In a retrospective analysis of a sarcoma database at a single institution between 1990 and 2014, we identified 1446 patients with non-metastatic and 346 with metastatic bone sarcoma. Low-grade types of tumour were excluded. Our data included the demographics of the patients, the characteristics of the tumour, and the survival outcome of patients. Cox proportional hazards analysis and Kaplan-Meier survival analysis were performed, and the survivorship of the non-metastatic and metastatic cohorts were compared. Results: In the non-metastatic cohort, a longer DOS was associated with a slightly more favourable survival (hazard ratio (HR) 0.996, 95% confidence interval (CI) 0.994 to 0.998, p < 0.001). In all types of tumour, there was no difference in survival between patients with a DOS of greater than four months and those with a DOS of less than four months (p = 0.566). There was no correlation between the year of diagnosis and survival (p = 0.741). A diagnosis of chondrosarcoma (HR 0.636, 95% CI 0.474 to 0.854, p = 0.003) had the strongest positive effect on survival, while location in the axial skeleton (HR 1.76, 95% CI 1.36 to 2.29, p < 0.001) had the strongest negative effect on survival. Larger size of tumour (HR 1.05, 95% CI 1.03 to 1.06, p < 0.001) and increased age of the patient (HR 1.02, 95% CI 1.01 to 1.03, p < 0.001) had a slightly negative effect on survival. Metastatic and non-metastatic cohorts had similar median DOS (16 weeks, p = 0.277), although the median survival (15.5 months vs 41 months) and rates of survival at one year (69% vs 89%) and five years (20% vs 59%) were significantly shorter in the metastatic cohort. Conclusion: A longer DOS prior to diagnosis is not associated with a poorer overall survival in patients with a primary bone sarcoma. Location in the axial skeleton remains the strongest predictor of a worse prognosis. This may be helpful in counselling patients referred for evaluation on a delayed basis.

Pre-operative evaluation prior to soft tissue sarcoma excision - Why can't we get it right?

BACKGROUND: To define the association between an appropriate pre-operative workup (pre-operative advanced imaging studies, diagnostic biopsy) and incomplete soft tissue sarcoma (STS) excision. PATIENTS AND METHODS: This was a retrospective review of 397 consecutive patient records (2000-2008), looking at primary site advanced imaging (MRI or CT) and diagnostic biopsy procedures completed prior to the initial attempt at definitive surgical excision. Downstream effects of an inadequate pre-operative workup were also evaluated, including time to referral to a sarcoma multi-disciplinary care team and perceived alteration of surgical care in order to obtain a complete excision of the altered sarcoma bed. RESULTS: Thirty-eight percent (149/397) of soft tissue sarcomas identified underwent an incomplete excision prior to referral. A significant difference in the incidence of pre-operative primary site advanced imaging (91% vs. 42%, p < 0.001) and a pre-operative diagnostic biopsy (85% vs. 16%, p < 0.001) was found between the wide excision group and incomplete excision groups. Pre-operative biopsy (p < 0.001), tumor size >5 cm (p < 0.001), and a referral from an orthopaedic surgeon (p < 0.02) were all associated with reduced risk of incomplete excision in multivariate analysis. Seventy-four percent of patients in the incomplete excision group required an alteration in their definitive wide margin surgical resection, including rotational muscle flap coverage (37%), free flap coverage (11%), or amputation (11%). CONCLUSION: A minority of patients referred following incomplete excision of a STS had undergone an appropriate pre-operative workup prior to referral, leading to increased long-term morbidity following definitive re-excision. Education efforts to heighten awareness of suspicious soft tissue lesions remain vital.

American Brachytherapy Society consensus statement for soft tissue sarcoma brachytherapy.

PURPOSE: Radiation therapy represents an essential treatment option in the management of soft tissue sarcomas (STS). Brachytherapy represents an important subset of radiation therapy techniques used for STS, with evolving indications and applications. Therefore, the purpose of this guideline was to update clinicians regarding the data surrounding brachytherapy (BT) and provide recommendations for the utilization of BT in patients with STS. METHODS AND MATERIALS: Members of the American Brachytherapy Society with expertise in STS, and STS BT in particular, created an updated guideline for the use of BT in STS based on a literature review and clinical experience. RESULTS: Guidelines are presented with respect to dose and fractionation and technical features to improve outcomes and potentially reduce the risk of toxicity. Brachytherapy as monotherapy can be considered in low-risk cases or in situations where re-irradiation is being considered. Brachytherapy boost can be considered in cases at higher risk of recurrence or where BT alone cannot adequately cover the target volume. To limit wound complications, the start of BT delivery should be delayed until final wound closure, or if after immediate reconstruction, started after postoperative Day 5. CONCLUSIONS: The current guidelines have been created to provide clinicians with a review of the data supporting BT in the management of STS as well as providing indications and technique guidelines to ensure optimal patient selection and clinical outcomes.

How did formative research inform the development of a women's group intervention in rural Nepal?

Inability to reduce neonatal and maternal mortality in poor countries is sometimes blamed on a lack of contextual knowledge about care practices and care-seeking behavior. There is a lack of knowledge about how to translate formative research into effective interventions to improve maternal and newborn health. We describe the findings of formative research and how they were used to inform the development of such an intervention in rural Nepal. Formative research was carried out in four parts. Part 1 involved familiarization with the study area and literature review, and parts 2, 3 and 4 involved community mapping, audit of health services, and qualitative and quantitative studies of perinatal care behaviors. Participatory approaches have been successful at reducing neonatal mortality and may be suitable in our context. Community mapping and profiling helped to describe the community context, and we found that community-based organizations often sought to involve the Female Community Health Volunteer in community mobilization. She was not routinely conducting monthly meetings and found them difficult to sustain without support and supervision. In health facilities, most primary care staff were in post, but doctors and staff nurses were absent from referral centers. Mortality estimates reflected under-reporting of deaths and hygiene and infection control strategies had low coverage. The majority of women give birth at home with their mother-in-law, friends and neighbors. Care during perinatal illness was usually sought from traditional healers. Cultural issues of shyness, fear and normalcy restricted women's behavior during pregnancy, birth and the postpartum period, and decisions about her health were usually made after communications with the family and community. The formative research indicated the type of intervention that could be successful. It should be community-based and should not be exclusively for pregnant women. It should address negotiations within families, and should tailor information to the needs of local groups and particular stakeholders such as mothers-in-law and traditional healers. The intervention should not only accept cultural constructs but also be a forum in which to discuss ideas of pollution, shame and seclusion. We used these guidelines to develop a participatory, community-based women's group intervention, facilitated through a community action cycle. The success of our intervention may be because of its acceptability at the community level and its sensitivity to the needs and beliefs of families and communities.
