Effects of Different Treatment Strategies and Tumor Stage on Survival of Patients with Advanced Laryngeal Carcinoma: A 15-Year Cohort Study.

Background: Laryngeal cancer is the second most common cancer in the head and neck. Since laryngeal cancer management is a complex process, there is still no standard strategy to treat this disease in order to increase the survival rate of the patients especially among those with advanced form of the disease.

Methods: A cohort study was undertaken to analyze factors predicting survival of the patients in advanced stage laryngeal cancer in the Southern Iran among all patients newly diagnosed with laryngeal cancer between 2000 and 2015.

Socioeconomic Factors, Health Behavior, and Late-Stage Diagnosis of Breast Cancer: Considering the Impact of Delay in Diagnosis.

Background: Stage of cancer at diagnosis is one of the most important factors in patient prognosis. By controlling for diagnostic delay, this study aimed to identify factors associated with late-stage breast cancer (BC).

Patients And Methods: From November 2014 to January 2017, required information on 497 patients who were newly diagnosed with BC was obtained from patients' medical records.

Risk Factors Predicting Colorectal Cancer Recurrence Following Initial Treatment: A 5-year Cohort Study.

Purpose: Recurrence is one of the most important factors influencing survival of colorectal cancer patients. Subjects and Methods: In this cohort study, clinical and demographic characteristics of 561 patients with colorectal cancer were collected from 2010 to 2015. Medical records and telephone interviews were used to define the patient’s clinical status including the date of any recurrence during the study period.

Factors predicting survival in patients with early stage laryngeal cancer: A cohort study between 2000 to 2015.

Purpose: In recent years, trends of treatment and survival of laryngeal cancer have received heightened attention. Despite the fact that most laryngeal cancers are diagnosed at early stage, a concern of worsening survival in patients with localized cancer has been raised but not consistently observed. This study aimed to determine factors affecting laryngeal cancer survival.

Hair Coloring, Stress, and Smoking Increase the Risk of Breast Cancer: A Case-Control Study.

Purpose: Epidemiologic characteristics of breast cancer in Iran are significantly different from those in the West and even other regional countries, but little is known about the related factors.

Patients And Methods: A hospital-based case-control study was conducted on 1052 women (526 new cases and 526 controls). Logistic regression was performed to investigate associations of study factors with breast cancer risk.

Applying Additive Hazards Models for Analyzing Survival in Patients with Colorectal Cancer in Fars Province, Southern Iran.

Introduction: Colorectal cancer (CRC) is a commonly fatal cancer that ranks as third worldwide and third and the fifth in Iranian women and men, respectively. There are several methods for analyzing time to event data. Additive hazards regression models take priority over the popular Cox proportional hazards model if the absolute hazard (risk) change instead of hazard ratio is of primary concern, or a proportionality assumption is not made.

Prognostic Significance of Mucinous Histologic Subtype on Oncologic Outcomes in Patients With Colorectal Cancer.

Purpose: Mucinous adenocarcinomas account for about 10% of all colorectal cancers. This study aimed to investigate the prognostic impact of mucinous histologic subtype on oncologic outcomes in patients with colorectal cancer.

Methods: This retrospective study was performed at two large tertiary university hospitals.

Impact of social and clinical factors on diagnostic delay of breast cancer: A Cross-sectional Study.

One of the reasons for high mortality of breast cancer is long delay in seeking medical care. This study was designed to measure the association of a wide range of socio-demographic and clinical factors with the diagnostic delay in breast cancer among Iranian patients.This study was conducted on 505 newly diagnosed patients with breast cancer from southern part of Iran.

Factors Affecting Survival in Patients with Colorectal Cancer in Shiraz, Iran.

Background: Colorectal cancer (CRC) is the third most common cancer in the world, and the fourth in Iran in both genders. The aim of this study was to find predictive factors for CRC survival.

Materials And Methods: Medical records of 570 patients referred to the radiotherapy oncology department of Shiraz Namazi hospital from 2005 to 2010 were retrospectively analysed.

Efficacy and Safety of Low-Dose-Rate Endorectal Brachytherapy as a Boost to Neoadjuvant Chemoradiation in the Treatment of Locally Advanced Distal Rectal Cancer: A Phase-II Clinical Trial.

Purpose: Despite advances in rectal cancer treatment over the last decade, local control and risk of late side effects due to external beam radiation therapy (EBRT) remain as concerns. The present study aimed to investigate the efficacy and the safety of low-dose-rate endorectal brachytherapy (LDRBT) as a boost to neoadjuvant chemoradiation for use in treating locally advanced distal rectal adenocarcinomas.

Methods: This phase-II clinical trial included 34 patients (as the study arm) with newly diagnosed, locally advanced (clinical T3-T4 and/or N1/N2, M0) lower rectal cancer.
