The aim of this study was to examine the prognostic factors and treatment outcomes of cervical esophageal carcinoma (CEC) patients who underwent definitive chemoradiotherapy (CRT). The clinical data of 175 biopsy-confirmed CEC patients treated with definitive CRT between April 2005 and September 2021 were retrospectively analyzed. The prognostic factors predicting overall survival (OS), progression-free survival (PFS), and local recurrence-free survival (LRFS) were assessed in uni- and multivariable analyses.

Methods And Study Design: The daily practices of radiation oncology centers for patients diagnosed with oropharyngeal cancer in 2010 were evaluated by a two-part questionnaire that separately assessed the information of the participating center and the charts of the treated patients.
Results: A total of 22 centers participated in the study, and 105 oropharyngeal cancer patients reported for our review.

Objectives: This study aims to compare the carotid artery doses applied with various radiotherapy techniques for the treatment of T1N0 glottic larynx cancer.
Patients And Methods: Five patients were simulated with using computed tomography (CT). Clinical (CTV) and planning target volumes (PTV) were created for T1N0 glottic larynx cancer.
A review for solitary plasmacytoma of bone and extramedullary plasmacytoma.
ScientificWorldJournal
September 2012
Article Synopsis
- Solitary plasmacytoma (SP) is a type of cancer featuring a single mass of abnormal plasma cells, either in bone (SBP) or soft tissue (EMP), without systemic signs of myeloma; biopsy is needed for diagnosis.
- SBP typically occurs in the axial skeleton, while EMP is found in the head and neck; it affects males more than females (2:1) with a median age of 55, and has a higher incidence in Black individuals compared to White individuals.
- SBP has a concerning risk of progressing to myeloma, and treatment primarily involves radiotherapy (RT) with at least 4000 cGy; about 30% of SBP patients
Outcome and prognostic factors in olfactory neuroblastoma: a rare cancer network study.
Int J Radiat Oncol Biol Phys
November 2010
Purpose: To assess the outcome in patients with olfactory neuroblastoma (ONB).
Methods And Materials: Seventy-seven patients treated for nonmetastatic ONB between 1971 and 2004 were included. According to Kadish classification, there were 11 patients with Stage A, 29 with Stage B, and 37 with Stage C.
Purpose: This study reports the long term outcomes of postoperative radiotherapy in patients with resection for non-small-cell lung cancer (NSCLC).
Methods And Materials: A total of 98 patients with resected NSCLC who received postoperative radiotherapy (PORT) between January 1994 and December 2004 were retrospectively analyzed. The most frequently performed surgical procedure was lobectomy (59 patients), followed by pneumonectomy (25), wedge resection (8), and bilobectomy (6).
Article Synopsis
- The study assessed the relationship between anxiety and depression levels and coping mechanisms among women undergoing treatment for breast cancer.
- The research utilized psychological inventories and quality of life questionnaires to evaluate the patients' emotional well-being and support systems.
- Findings revealed significant levels of anxiety and depression, with factors like lack of social support and coping strategies linking to poorer quality of life and emotional health.

Int J Radiat Oncol Biol Phys
December 2008
Purpose: To determine the patterns of care for lung cancer in Turkish radiation oncology centers.
Methods And Materials: Questionnaire forms from 21 of 24 (87.5%) centers that responded were evaluated.
To identify the outcomes of prognostic factors of solitary plasmacytoma mainly treated with local radiotherapy (RT). The data were collected from 80 patients with solitary plasmacytoma (SP). Forty patients (50.

Forty-three patients with stage III NSCLC were treated with 60Gy external beam radiotherapy (ERT) and three applications of 5Gy each of HDR-EB (group A). Seventy-four patients who did not receive previous RT were treated with 30Gy ERT and two applications of 7.

Methods: Between 1983 and 2000, 122 patients with primary or recurrent squamous cell carcinoma of the oropharynx or oral cavity received interstitial brachytherapy as part of their overall management. Forty patients had primary, unresected carcinoma of the base of tongue and are the subjects of this analysis.
