The treatment of multi-drug resistant (MDR) cancer is a clinical challenge. Many MDR cells over-express epidermal growth factor receptor (EGFR). We exploit this expression through the development of EGFR-targeted, polymer blend nanocarriers for the treatment of MDR cancer using paclitaxel (a common chemotherapeutic agent) and lonidamine (an experimental drug; mitochondrial hexokinase 2 inhibitor). An orthotopic model of MDR human breast cancer was developed in nude mice and used to evaluate the safety and efficacy of nanoparticle treatment. The efficacy parameters included tumor volume measurements from day 0 through 28 days post-treatment, terminal tumor weight measurements, tumor density and morphology assessment …

Mesothelioma is an uncommon tumor. It has a latency period of 20-40 years. The most important risk factor is asbestos exposure. Prognosis of mesothelioma is generally poor with high case-fatality rate, and research to improve the outcome of this disease is on-going worldwide. Due to its rarity, management by a multidisciplinary team with experience is recommended. Carefully selected patients may benefit from tri-modality (surgery, radiotherapy and chemotherapy) treatment. The management of pleural and peritoneal mesothelioma is summarized in this review. Recent advances in chemotherapy and biologic response modifiers are promising.

Smoking, air pollution and radon exposure are causally related to lung cancer. This review analyzes trends of smoking habits by age, sex and ethnicity and their correlation with incidence and mortality of lung cancer. Unfortunately the use of tobacco by adolescents is on the rise. Most developed countries are still showing the rising trend of mortality in female smokers. In Asia, cigarette smoking has become a major health risk with one in three of all cigarettes in the world today are smoked in China. Estimated one hundred million young ( < 29 years old) Chinese smokers will eventually die from lung …

New technological concepts have been evolving to manage the relative poor prognosis of lung cancer. Brachytherapy is becoming an option for both unresectable and early resectable lung cancer. Three-dimensional ultrasound (US) of lung tumours and image-guided minimally invasive robotics-assisted brachytherapy are feasible for dosimetry planning and management of lung tumours. The present article reviews the current knowledge of lung brachytherapy and discusses its potential in future management of lung cancer.

The development of resistance to variety of chemotherapeutic agents is one of the major challenges in effective cancer treatment. Tumor cells are able to generate a multi-drug resistance (MDR) phenotype due to microenvironmental selection pressures. This review addresses the use of nanotechnology-based delivery systems to overcome MDR in solid tumors. Our own work along with evidence from the literature illustrates the development of various types of engineered nanocarriers specifically designed to enhance tumor-targeted delivery through passive and active targeting strategies. Additionally, multi-functional nanocarriers are developed to enhance drug delivery and overcome MDR by either simultaneous or sequential delivery of resistance …

OBJECTIVE: To assess the impact of radiation management on male breast cancer (MBC) at London Regional Cancer Program (LRCP). METHODS AND MATERIALS: Men with a diagnosis of breast cancer referred to LRCP were reviewed. The seventh American Joint Committee on Cancer staging system was used. Patients treated with and without post-mastectomy radiation therapy (PMRT) were analyzed. Disease-free survival (DFS) was defined as time duration from diagnosis to first recurrence. Overall survival (OS) was defined as time duration from pathologic diagnosis to death or last follow-up with any death defined as an event. Survival estimates were obtained using Kaplan-Meier methodology. RESULTS: …

Brachytherapy With Permanent Gold Grain Seeds For Squamous Cell Carcinoma Of The Lip, Michael Lock
Michael Lock
Abstract PURPOSE: To describe the use of radioactive gold grain implantation for squamous cell carcinoma of the lip. METHODS: Retrospective review of 51 patients treated with permanent gold ((198)Au) grain implant brachytherapy. The seed arrangement delivered a dose of 5500 cGy at 0.5 cm from a single plane. Primary endpoints were local recurrence and cosmetic outcome. RESULTS: Median follow-up was 27 months. Median age was 69 years. The majority (90%) were T1 lesions. None of the patients had evidence of regional lymph node or distant metastasis. Twelve patients had recurrent disease with prior surgery and five patients had previous head …

A Phase Ii Trial Of Arc-Based Hypofractionated Intensity-Modulated Radiotherapy In Localized Prostate Cancer, Michael Lock
Michael Lock
Abstract PURPOSE: To evaluate acute and late genitourinary (GU) and gastrointestinal (GI) toxicity and biochemical control of hypofractionated, image-guided (fiducial markers or ultrasound guidance), simplified intensity-modulated arc therapy for localized prostate cancer. METHODS AND MATERIALS: This Phase II prospective clinical trial for T1a-2cNXM0 prostate cancer enrolled 66 patients who received 63.2 Gy in 20 fractions over 4 weeks. Fiducial markers were used for image guidance in 30 patients and daily ultrasound for the remainder. Toxicity was scored according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. RESULTS: Median follow-up was 36 months. Acute Phase Grade …

Issues Related To Sentinel Lymph Node Assessment In The Management Of Breast Cancer—What Are Relevant In Pathology Reports?, Patricia Tai, Kurian J. Joseph, Edward Yu

Most cancer centers now perform sentinel node (SN) biopsies. The limited number of SNs sampled compared with an axillary dissection has allowed more comprehensive lymph node analysis resulting in increased detection of micrometastases. Many node-negative cases are now reclassified as micrometastatic. Recent research on SN biopsy focuses on whether axillary dissection is always necessary when the SN is positive. Some subgroups of patients have a higher risk of more nodal metastases when completion axillary dissections were performed. This paper summarizes the different studies and examines what are the clinically relevant items to report on SN node pathology: volume or size …
