Background: Multifocality, multicentricity and extension beyond the prostate capsule are all characteristics of prostatic adenocarcinoma that may escape diagnosis by conventional CT scanning or MRI. This study was designed to assess the diagnostic value of magnetic resonance spectroscopy (MRS) in prostatic carcinoma and its compatibility with prostatic specific antigen (PSA) as the conventional...
background and aim: carcinoma of the uterine cervix is a significant cause of mortality because of malignancy in women. radiotherapy is a major treatment modality for invasive cervical cancer with good treatment outcome in early-stage patients. however, substantial treatment failures still occur in the advanced-stage patients. in this case report a long term follow up of a 58 years old woman wi...
Although Epstein-Barr virus-associated nasopharyngeal carcinoma (NPC) is a highly radiosensitive cancer, approximately 20% of patients with NPC develop local recurrence after radiation therapy. Multiple proinflammatory cytokines are thought to protect NPC tumor cells from immune surveillance and therapeutic interventions. The cytokine leukemia inhibitory factor (LIF) is a critical component of ...
OBJECTIVE To review the 2- to 17-year outcome of nasopharyngectomy following local recurrence of nasopharyngeal carcinoma. DESIGN Retrospective review. SETTING University medical center. PATIENTS Thirty-seven patients with biopsy-proven recurrent nasopharyngeal cancer followed up for a minimum of 2 years after transpalatal, transmaxillary, and/or transcervical resection with and without n...
BACKGROUND Hypoxic cancer cells are thought to be radioresistant and could impact local recurrence after radiotherapy (RT). One of the major hypoxic imaging modalities is [18F]fluoromisonidazole positron emission tomography (FMISO-PET). High FMISO uptake before RT could indicate radioresistant sites and might be associated with future local recurrence. The predictive value of FMISO-PET for intr...
the postgastrectomy recurrence rate is as high as 30-65%, with 5-year overall survival rates of <20%. local recurrence is very common which occurs in 38-45% of cases. the most common sites of locoregional recurrence are the gastric remnant at the anastomosis, the gastric bed, and the regional nodes. the recurrence may occur as early and late events after gastrectomy. most recurrences are early,...
We present the case of a 47-year-old man with a history of Epstein-Barr-virus-positive nasopharyngeal carcino- ma who developed a metastasis to the palatine tonsil. To the best of our knowledge, this is the first reported case of an intratonsillar metastasis of a nasopharyngeal carcinoma. The aim of this report is to emphasize the importance of vigilant surveillance in patients with nasopharyng...
BACKGROUND To investigate the clinical feature and the local failure patterns after intensity-modulated radiotherapy for nasopharyngeal carcinoma. METHODS Between March 2007 and July 2009, 710 patients with nasopharyngeal carcinoma were treated with intensity-modulated radiotherapy. The magnetic resonance imagings obtained at recurrence were registered with the original planning computed tomo...
OBJECTIVES/HYPOTHESIS To determine the long-term outcomes of a prospective cohort of 20 patients who had nasopharyngectomy using an open partial-maxillectomy approach. METHOD A prospective cohort study of the surgical outcomes of patients with recurrent T1 (rT1) and rT2 nasopharyngeal carcinoma recurrence. RESULTS There were 14 male and six female patients. The mean age was 49 years. The me...
PURPOSE To evaluate the potential risk factors for distant metastasis of nasopharyngeal carcinoma in Chinese patients following standard intensity-modulated radiotherapy and chemotherapy. METHODS The potential risk factors for distant metastasis in 622 patients with newly-diagnosed primary nasopharyngeal carcinoma following standard radiotherapy and chemotherapy were evaluated retrospectively...
