: Delirium has been the most frequent neuropsychiatric complication in patients with advanced cancer. This exploratory study aimed to determine the proportion of patients who were able to recall their experience of delirium and the level of distress experienced by patients, family caregivers, and healthcare professionals. ⋯ : The majority of patients with advanced cancer recalled their experience of delirium, causing moderate to severe distress in both patients and family caregivers. Appropriate interventions to reduce this distress are needed. Cancer 2009. (c) 2009 American Cancer Society.

: Palliative care has been progressively adopted by American cancer centers; however, referrals to palliative care continue to occur late in the trajectory of illness. It was hypothesized that the perceived association between the name palliative care and hospice was a barrier to early patients' referral. The objectives of this study were to determine the perception of the impact of the name palliative care compared with supportive care on patient referral and to determine whether there was an association between demographic factors and the perceptions of the 2 names by medical oncologists and their midlevel providers (advance practice nurses and physician assistants) at a comprehensive cancer center. ⋯ : The name palliative care was perceived by medical oncologists and midlevel providers as more distressing and reducing hope to patients and families. Medical oncologists and midlevel providers significantly prefer the name supportive care and stated more likelihood to refer patients on active primary and advanced cancer treatments to a service named supportive care.

Randomized trials supported the use of androgen deprivation therapy (ADT) with radiation therapy (RT) for intermediate-risk prostate cancer. However, the value of concurrent ADT was less certain with dose-escalated RT. Better methods of stratifying patients in this risk group may help select patients who are most likely to benefit. ⋯ After dose-escalated external beam RT, intermediate-risk prostate cancer patients with PPC> or =50 had the highest risk for biochemical failure and may be most likely to derive a benefit from ADT.

Primary systemic chemotherapy has been a standard of care for the management of locally advanced breast cancer (LABC) patients and has increasingly been used for patients with large operable breast cancer. Pathologic complete response (pCR) of axillary lymph node metastases predicted an excellent probability of long-term disease-free and overall survival. Although the clinical significance of occult lymph node metastases in patients with breast cancer was extensively studied, their prognostic value in patients with LABC after primary chemotherapy was not known. This study evaluated the detection rate and clinical significance of occult lymph node metastases in lymph nodes that contained metastatic carcinoma at the time of initial diagnosis and converted to negative based on routine pathologic examination after primary systemic chemotherapy. ⋯ Persistent occult axillary lymph node metastases were not uncommon in patients with axillary lymph node-positive LABC who experienced a pCR in involved lymph nodes after preoperative chemotherapy. However, such occult metastases did not adversely affect the good prognosis associated with axillary lymph node pCR. Therefore, routine lymph node CK evaluation was not recommended after primary chemotherapy.

Optical spectroscopy is a noninvasive technique with potential applications for diagnosis of oral dysplasia and early cancer. In this study, we evaluated the diagnostic performance of a depth-sensitive optical spectroscopy (DSOS) system for distinguishing dysplasia and carcinoma from non-neoplastic oral mucosa. ⋯ The ability to selectively target epithelial and shallow stromal depth regions appeared to be diagnostically useful. For nonkeratinized oral sites, the sensitivity and specificity of this objective diagnostic technique were comparable to that of clinical diagnosis by expert observers. Thus, DSOS has potential to augment oral cancer screening efforts in community settings.
