Radiation therapy is one of the most cost-effective ways to treat cancer patients on both a curative and palliative basis in low- and middle-income countries (LMICs). Despite this, the gap in radiation oncology capacity is enormous and is even increasing due to a rapid rise in the incidence of cancer cases in LMICs. The urgent need for radiotherapy resources in terms of bunkers and megavoltage machines is important, but equally important is the tremendous lack of properly educated health care professionals...

The use of 4 cycles of cisplatin-based adjuvant chemotherapy is now the standard of care for patients with resected stage II and IIIA non-small cell lung cancer. Neoadjuvant chemotherapy lacks the same level of data as adjuvant treatment, but meta-analyses of this approach support its use. Selection of patients who are most likely to benefit from chemotherapy remain elusive. Ongoing adjuvant trials are exploring biomarkers, molecularly targeted agents, postoperative radiation therapy, and immunotherapy.

BACKGROUND: Cancer care in Alberta, Canada is publicly funded and provides patients with access to health care facilities and providers. The distribution of patients and health services across Alberta presents challenges to the delivery of cancer care, especially radiation therapy. In this study, we examined the association between patient and health system factors, the use of radiation therapy and survival outcomes in patients with stage III non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: The provincial cancer registry was used to identify all patients who presented with clinical stage III NSCLC, diagnosed from 2005 to 2007, in Alberta...

PURPOSE: At present, a one-size-fits-all approach is typically used for cancer therapy in patients. This is mainly because there is no current imaging-based clinical standard for the early assessment and monitoring of cancer treatment response. Here, the authors have developed, for the first time, a complete computer-aided-prognosis (CAP) system based on multiparametric quantitative ultrasound (QUS) spectroscopy methods in association with texture descriptors and advanced machine learning techniques...

BACKGROUND: Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third most common cause of cancer-related deaths. Hepatic resection and liver transplantation are considered to be the preferred treatment for HCC. However, as novel therapeutic options such as image-guided locoregional therapies have emerged and been refined, the manner in which HCC is treated has changed dramatically compared with what it was considered just 2 decades earlier. SUMMARY: This study reviews the current results of various image-guided locoregional therapies for treating HCC, especially focusing on thermal ablative and transarterial techniques...

Answer questions and earn CME/CNE Laryngeal cancer remains one of the most common tumors of the respiratory tract. Fortunately, significant advancements have been made over the past decade in the treatment of laryngeal cancer. Although surgery has been the historical mainstay for localized disease and still is an integral part of treatment, nonsurgical options like radiation and systemic therapy have emerged as viable options. In addition, in the metastatic setting, novel agents are showing promise for this patient population...

Harmonious interactions between radiation, medical, interventional and surgical oncologists, as well as other members of multidisciplinary teams, are essential for the optimization of patient care in oncology. This multidisciplinary approach is particularly important in the current landscape, in which standard-of-care approaches to cancer treatment are evolving towards highly targeted treatments, precise image guidance and personalized cancer therapy. Herein, we highlight the importance of multidisciplinarity and interdisciplinarity at all levels of clinical oncology training...

BACKGROUND: Molecular profiling using breast cancer subtype has an increasing role in the multidisciplinary care of the breast cancer patient. We sought to determine the role of breast cancer subtyping in breast reconstruction and specifically if breast cancer subtyping can determine the need for postmastectomy radiation therapy (PMRT) and predict recurrence-free survival (RFS) to plan for the timing and technique of breast reconstruction. METHODS: We reviewed prospectively collected data from 1931 reconstructed breasts in breast cancer patients who underwent mastectomy between November 1999 and December 2012...

With the rapid rise in the incidence of thyroid cancer, the number of thyroidectomies has increased remarkably in the last 10 years. Thyroidectomy accounts for approximately 40% of the workload in head and neck fellowship. The decision making in thyroid surgery is quite complex, especially when patients present with recurrent or advanced thyroid cancer. The complications of thyroid surgery can be very serious in relation to quality of life. Some of these complications can be avoided with meticulous surgical technique...

Stereotactic ablative body radiotherapy (SABR) describes a radiotherapy technique where high doses of radiation are precisely delivered to an extra-cranial target within the body, using either a single fraction of radiotherapy or using multiple small number of fractions. SABR has now become the standard of care treatment for patients with early stage NSCLC for whom surgery is not appropriate. This systematic review considers the evidence supporting the use of SABR in early stage NSCLC, reported toxicity rates, the use of SABR in centrally located NSCLC, the use of SABR as salvage therapy following surgery or radiotherapy and future potential drug combinations with SABR...

Because of the rarity of esophageal melanoma, the optimal management of this disease is limited. The pooled dataset in the National Cancer Database (NCDB) was used to identify the prognostic factors and treatment outcomes. Patients who were diagnosed with esophageal melanoma between 2004 and 2011 were identified. Patients were stratified as either localized (T1-4N0M0), regional (T1-4N+M0), or metastatic (M1). The primary endpoint of this study was overall survival (OS) which was analyzed using the Kaplan-Meier method and multivariate Cox regression, which was performed to identify potential factors influencing survival...
