Prostate cancer frequently metastasizes to bone, but bone marrow involvement is relatively less common. In advanced prostate cancer, significant bone marrow infiltration can result in hematologic abnormalities such as anemia and thrombocytopenia. We report the case of a patient who presented with a new diagnosis of thrombocytopenia at the same time that he presented with prostate cancer metastatic to bone. He was found to have immune thrombocytopenia (itp) which responded to treatment with steroids. We discuss this case and review the literature on itp in the setting of advanced malignancy...

A 49-year-old woman presents with an extensive violaceous rash, rapidly progressive proximal muscle weakness, and dysphagia to solids, consistent with a diagnosis of dermatomyositis. Two weeks later, she palpates a mass in her left breast and is diagnosed with her2-positive metastatic invasive ductal carcinoma of the breast. There is a well-established association between dermatomyositis and malignancy. However, the specific association between breast cancer and dermatomyositis has not been well characterized...

Tuberous sclerosis complex (tsc), a phacomatosis, is a rare genetic disease (autosomal dominant; incidence: 1 in 6,800-17,300) associated with mutations in the TSC1 and TSC2 genes, 70% of which are sporadic. The disease causes benign tumours in the brain, kidneys, heart, lungs, skin, and eyes; thyroid lesions are extremely rare. A 13-year-old euthyroid boy with a hereditary form of tsc (del 4730G in TSC2, also seen in 2 sisters and the father) was admitted to hospital with a thyroid nodule. Physical examination revealed a nodular left lobe with increased consistency...

BACKGROUND: Oncoplastic breast surgery combines traditional oncologic breast conservation with plastic surgery techniques to achieve improved aesthetic and quality-of-life outcomes without sacrificing oncologic safety. Clinical uptake and training remain limited in the Canadian surgical system. In the present article, we detail the current state of oncoplastic surgery (ops) training in Canada, the United States, and worldwide, as well as the experience of a Canadian clinical fellow in ops...

BACKGROUND: In 2009, a Rapid Access Breast Clinic (rabc) was opened at our urban hospital. Compared with the traditional system (ts), the navigated care through the clinic was associated with a significantly shorter time to surgical consultation. Since 2009, many radiology facilities have introduced facilitated-care pathways for patients with breast pathology. Our objective was to determine if that change in diagnostic imaging pathways had eliminated the advantage in time to care previously shown for the rabc...

BACKGROUND: The efficacy of carboplatin-paclitaxel in the trimodality setting was demonstrated in the cross trial. Because of better tolerance, that regimen has been adopted as an alternative for patients receiving definitive chemoradiation (dcrt). The purpose of our study was to compare outcomes in patients with localized esophageal and gastroesophageal junction (gej) cancer who received dcrt using either platinum-5-fluorouracil (5fu) or carboplatin-paclitaxel. METHODS: Medical records and outcomes for all patients diagnosed with localized carcinoma of the esophagus and gej at our centre between 2008 and 2015 were reviewed...

OBJECTIVE: We estimated the frequency of occult gynecologic primary tumours (gpts) in patients with metastatic cancer from an uncertain primary and evaluated the effect on disease management and overall survival (os). METHODS: We used Manitoba administrative health databases to identify all patients initially diagnosed with metastatic cancer during 2002-2011. We defined patients as having an "occult" primary tumour if the primary was classified at least 6 months after the initial diagnosis...

PURPOSE: We assessed response to treatment, toxicity, time to progression, progression-free survival, and overall survival in patients newly diagnosed with multiple myeloma who were ineligible for or unwilling to undergo transplantation and who were treated with a combination of lenalidomide and low-dose dexamethasone for a fixed 6 cycles in a resource-constrained environment. METHODS: This pragmatic study, conducted in a single tertiary cancer centre in South India, enrolled patients from May 2009 till April 2011...

OBJECTIVES: Diagnostic assessment programs (daps) appear to improve the diagnosis of cancer, but evidence of their cost-effectiveness is lacking. Given that no earlier study used secondary financial data to estimate the cost of diagnostic tests in the province of Ontario, we explored how to use secondary financial data to retrieve the cost of key diagnostic test services in daps, and we tested the reliability of that cost-retrieving method with hospital-reported costs in preparation for future cost-effectiveness studies...

INTRODUCTION: Patients with breast cancer (bca) who overexpress her2 (the human epidermal growth factor receptor 2) are at risk for cardiotoxicity when treated with anthracycline-based chemotherapy and her2-targeted agents. The Framingham risk score (frs) is a validated tool that stratifies patients into high-, intermediate-, or low-risk groups and calculates their 10-year risk of developing cardiovascular disease (cvd) based on past medical history, systolic blood pressure, and measurement of serum lipids...

BACKGROUND: "Conditional survival probability" is defined as the probability that a patient will survive an additional time, given that the patient has already survived a defined period of time after diagnosis. Such estimates might be more relevant for clinicians and patients during post-diagnosis care, because survival probability projections are based on the patient's survival to date. Here, we provides the first population-based estimates of conditional survival probabilities by histology for brain cancer in Canada...

BACKGROUND: Communication with health care providers during diagnosis and treatment planning is of special importance because it can influence a patient's emotional state, attitude, and decisions about their care. Qualitative evidence suggests that some patients experience poor communication with health care providers and have negative experiences when receiving their cancer diagnosis. Here, we use survey data from 8 provinces to present findings about the experiences of Canadian patients, specifically with respect to patient-provider communication, during the diagnosis and treatment planning phases of their cancer care...

BACKGROUND: Resection is the cornerstone of cure for gastric adenocarcinoma; however, several aspects of surgical intervention remain controversial or are suboptimally applied at a population level, including staging, extent of lymphadenectomy (lnd), minimum number of lymph nodes that have to be assessed, gross resection margins, use of minimally invasive surgery, and relationship of surgical volumes with patient outcomes and resection in stage iv gastric cancer. METHODS: Literature searches were conducted in databases including medline (up to 10 June 2016), embase (up to week 24 of 2016), the Cochrane Library and various other practice guideline sites and guideline developer Web sites...

BACKGROUND: Radiotherapy (rt) has been the standard treatment for early oropharyngeal cancer, achieving excellent outcomes, but with significant toxicities. Transoral robotic surgery (tors) has emerged as a promising alternative. A decision aid (da) can help to establish patient treatment preferences. METHODS: A da was developed and piloted in 40 healthy adult volunteers. Assuming equal oncologic outcomes of the treatments, participants indicated their preference...

BACKGROUND: The use of neoadjuvant systemic therapy (nast) in the treatment of breast cancer is increasing, and the role of adjuvant radiation therapy (rt) in that setting is uncertain. We sought to review and report the use of nast, its trends over time, and its relationship with the prescribing patterns of locoregional rt in a provincial cancer system. METHODS: Patients with stages i-iii breast cancer diagnosed during 2007-2012 were identified using a provincial database...

BACKGROUND: Lung cancer continues to be one of the most common cancers in Canada, with approximately 28,400 new cases diagnosed each year. Although timely care can contribute substantially to quality of life for patients, it remains unclear whether it also improves patient outcomes. In this work, we used a set of quality indicators that aim to describe the quality of care in lung cancer patients. We assessed adherence with existing guidelines for timeliness of lung cancer care and concordance with existing standards of treatment, and we examined the association between timeliness of care and lung cancer survival...

BACKGROUND: The pan-Canadian Oncology Drug Review (pcodr) was implemented in 2011 to address uneven drug coverage and lack of transparency with respect to the various provincial cancer drug review processes in Canada. We evaluated the impact of the pcodr on provincial decision concordance and time from Notice of Compliance (noc) to drug funding. METHODS: In a retrospective review, Health Canada's Drug Product Database was used to identify new indications for cancer drugs between January 2003 and May 2014, and provincial formulary listings for drug-funding dates and decisions between 1 January 2003 and 31 December 2014 were retrieved...
