Background And Purpose: To investigate the association between progressive muscle loss and survival outcomes of patients with advanced-stage oral squamous cell carcinoma (OSCC) undergoing surgery and adjuvant (chemo)radiotherapy.
Methods: We analyzed the computed tomography (CT) scans of 155 patients with stage III-IVB OSCC at baseline, at simulation CT for radiotherapy, and at 3- and 9-months post-treatment. Skeletal muscle index (SMI) was measured using CT at the C3 vertebral level.
Objectives: Sarcopenia and systemic inflammation can affect survival of advanced-stage oral squamous cell carcinoma (OSCC) patients; however, their reciprocal associations with survival outcomes are yet to be investigated.
Study Design: Retrospective review at a tertiary cancer center.
Methods: Patients with stage III-IVB OSCC that underwent surgery and (chemo)radiotherapy at our institution between 2010 and 2015 were reviewed.
Rationale: The diagnosis of anaplastic lymphoma kinase (ALK)-negative inflammatory myofibroblastic tumors (IMT) remains challenging because of their morphological resemblance with spindle cell sarcoma with myofibroblastic characteristics.
Patient Concerns: A 69-year-old female patient presented with loco-regional recurrent IMT several times within 8 years after primary treatment and neck lymph node metastasis 3.5 years after last recurrence.
Background: This study aimed to evaluate the inter-fraction set-up error and intra-fraction motion during reverse semi-decubitus (RSD) breast radiotherapy, and to determine a planning target volume (PTV) margin.
Material And Methods: Pre- and post-treatment cone-beam computed tomography (CBCT) scans were prospectively acquired at fractions 1, 4, 7, 8, 11, and 14 for 30 patients who underwent RSD breast radiotherapy. Online correction for initial set-up error greater than 5 mm or 2° was performed and post-correction CBCT was acquired.
Background: Surgery followed by radiotherapy (RT) is indicated for patients with high-risk oral cavity cancer (OCC). Based on multi-institutional reports, we developed a guideline for postoperative RT for patients with OCC.
Methods: A multidisciplinary OCC team was recruited to develop a questionnaire concerning details of risk-factor categorization, target delineation, and dose specification.
Conclusion: IMRT provided better conformity, less toxicity and better function restoration for advanced hypopharyngeal carcinoma after major surgery with ileocolic flap reconstruction.
Objectives: To compare the results of adjuvant conventional radiotherapy (2DRT) with intensity modulated radiation therapy (IMRT) for locally advanced hypopharyngeal cancer after resection and ileocolic free flap reconstruction and to design treatment plans for those two modalities plus 3D conformal radiotherapy (3DCRT) for dose distribution comparison.
Methods: 13 locally advanced hypopharyngeal cancer patients were enrolled, 8 treated with 2DRT and 5 with IMRT.
