PURPOSE Definitive chemoradiation therapy remains the standard of care for patients with localized esophageal carcinoma who choose nonsurgical management. However, there is no consensus regarding delineation of the nodal clinical target volume (CTVn), especially for lower cervical lymph nodes. This study aimed to map the location of metastatic supraclavicular lymph nodes in thoracic esophageal ...

Background: The axillary and supraclavicular nodal volume treatment results in improvement of local control and survival after breast conserving surgery (BCS) or modified radical mastectomy (MRM). Studies on the depth of these nodes have questioned the consistent use of standard fields for all patients. This study was done to assess the dose delivery to these lymph nodes with conventional treat...

BACKGROUND Breast cancer is the most frequently diagnosed cancer and the leading global cause of cancer death among women worldwide. Radiotherapy plays a significant role in treatment of breast cancer and reduces locoregional recurrence and eventually improves survival. The treatment fields applied for breast cancer treatment include: tangential, axillary, supraclavicular and internal mammary f...

Radiotherapy plays an essential role in the management of breast cancer. Three-dimensional conformal radiation therapy (3D-CRT) is applied based on 3D image information of anatomy of patients. In 3D-CRT for breast cancer one of the common techniques is tangential technique. In this project, various parameters of tangential and supraclavicular fields are optimized. This project has been done on ...

The aim of this study was to evaluate the usefulness and accuracy of supraclavicular lymph node excision biopsy in the diagnosis of suspected supraclavicular lymph node metastasis of lung cancer. A retrospective review was performed to evaluate patients with suspected supraclavicular lymph node metastasis of lung cancer who underwent supraclavicular lymph node excision biopsy from January 2011 ...

abstract background: chest wall irradiation for early breast cancer affects forced vital capacity (fvc), forced expiratory volume in the first second of expiration (fev1) and may change peripheral oxygen saturation (spo2). in our institute chest wall is irradiated with a four field technique: two tangential and two oppositional anterior and posterior supraclavicular fields. regional recurrence ...

PURPOSE To evaluate the feasibility to detect activated brown adipose tissue (BAT) using single-time-point infrared thermography of the supraclavicular skin region under thermoneutral conditions. To this end, infrared thermography was compared with 18-F-FDG PET, the current reference standard for the detection of activated BAT. METHODS 120 patients were enrolled in this study. After exclusion...

background: we conducted a retrospective analysis to evaluate the impact of omission of supraclavicular radiotherapy on supraclavicular failure rate and treatment outcomes in n1 breast cancer patients with evaluation of prognostic factors that affected supraclavicular recurrence free survival. methods: this study analyzed the medical records of 109 patients with n1 breast cancer. all patients u...

As we know breast cancer is the second death reason in Iran. One step of treatment process is radiotherapy, which needs careful consideration of contouring and therapeutic techniques Lung, thyroid, spinal cord, trachea and humerus are sensitive organs in breast cancer radiation therapy.  The most clinical studies recommended two ways for delivering 95 percent of dose to supraclavicular and ...

Diagnosis and accurate staging of lung cancer is essential for selection of appropriate curative or palliative therapy and affects patient prognosis. Both invasive and non-invasive procedures are used for this purpose. We aimed to assess the frequency of no palpable supraclavicular lymph node metastases in lung cancer patients with enlarged mediastinal lymph nodes, and their impact on diagnosis...
