Selecting chemotherapy schedules for adjuvant treatment of early stage breast cancer, what is the rationale behind?
Breast cancer is one of the most prevalent cancers that oncologists are faced with in their clinics. The varieties of clinical features of the disease result to very different scenarios in the processes of treatment decision making. While classic factors of stage, grade, age and hormone receptor status are still the criterion for choosing treatment, a very delicate list of other prognostic and predictive factors have been entered to this field over recent two decades. The evidence-based medicine rules to treat patients based on the best evidences that have been found by powered randomized clinical trials. Different panels and guidelines gathering these evidences try to help oncologists to find the best treatment methods through the variable and sometimes contradicting results. As it is always the main objective, increasing the survival rates in addition to the ideal aim of curing the disease is usually the target. Finding the best and the most practical chemotherapy regimen against breast cancer needs to notice the biology of this disease and its varieties along with each individual patient condition. It is clear that not all patients need the most complicated and expensive treatment

The Effect of Neoadjuvant Therapy on Early Complications of Esophageal Cancer Surgery
Introduction: Early diagnosis and appropriate treatment is required in esophageal cancer due to its invasive nature. The aim of this study was to evaluate early post-esophagectomy complications in patients with esophageal cancer who received neoadjuvant chemoradiotherapy (NACR). Â Materials and Methods: This randomized clinical trial was carried out between 2009 and 2011. Patients with lower-third esophageal cancer were randomly assigned to one of two groups. The first group consisted of 50 patients receiving standard chemoradiotherapy (Group A) and then undergoing surgery, and the second group consisted of 50 patients undergoing surgery only (Group B). Patients were evaluated with respect to age, gender, clinical symptoms, type of pathology, time of surgery, perioperative blood loss, and number of lymph nodes resected as well as early post-operative complicate including leakage at the anastomosis site, chylothorax and pulmonary complications, hospitalization period, and mortality rate within the first 30 days after surgery. Â Results: The mean age of patients was 55 years. Seventy-two patients had squamous cell carcinoma (SCC) and 28 patients had adenocarcinoma (ACC). There was no significant difference between the two groups with respect to age, gender, time of surgery, complications including anastomotic leakage, chylothorax, pulmonary complications, cardiac complications, deep venous thrombosis (DVT), or mortality. However, there was a significant difference between the two groups regarding hospital stay, time of surgery, perioperative blood loss, and number of lymph nodes resected. Â Conclusion:Â The use of NACR did not increase early post-operative complications or mortality among patients with esophageal cancer
