PURPOSE To provide evidence-based recommendations to practicing physicians and other health care providers on the diagnosis and management of squamous cell carcinoma of unknown primary in the head and neck (SCCUP). METHODS The American Society of Clinical Oncology convened an Expert Panel of medical oncology, surgery, radiation oncology, radiology, pathology, and advocacy experts to conduct a literature search, which included systematic reviews, meta-analyses, randomized controlled trials, and prospective and retrospective comparative observational studies published from 2008 through 2019. Outcomes of interest included survival, local and regional disease control, and quality of life. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS The literature search identified 100 relevant studies to inform the evidence base for this guideline. Four main clinical questions were addressed, which included subquestions on preoperative evaluations, surgical diagnostic and therapeutic procedures, appropriate pathology techniques, and adjuvant therapy. RECOMMENDATIONS Evidence-based recommendations were developed to address preoperative evaluation for patients with a neck mass, surgical diagnostic and therapeutic procedures, appropriate treatment options in unilateral versus bilateral SCCUP.

Structural alterations of protooncogene sequences may be involved in the pathogenesis of human neoplasms. We screened 54 thyroid tumors (36 benign and 18 malignant) for gene rearrangements of the protooncogenes c-myc, c-myb, c-fos, c-erb-B1, c-erb-B2, c-erb-A, N-ras, K-ras, and H-ras. Only mutations of H-ras were observed. None of the 15 colloid adenomas examined had detectable H-ras rearrangements. Of the remaining tumors, we observed mutations of H-ras in 4 benign and 4 malignant neoplasms. Gene amplification was found in 5 tumors. An aggressive recurrent papillary carcinoma had a marked amplification of one of the H-ras alleles. The amplified allele was truncated, in that the 3' variable tandem repeat was not a part of the amplification unit, and contained a codon 12 point mutation leading to a valine for glycine substitution. We also observed the association of low copy gene amplification with a codon 12 valine for glycine mutation in a follicular adenoma. Two tumors contained H-ras EcoRI polymorphisms not present in the DNA of normal thyroid from the same individuals, and one follicular carcinoma showed loss of an H-ras allele. Ras protooncogenes may become transforming by quantitative mutations, leading to increased expression, or qualitative mechanisms, through activating point mutations. Both of these appear to coexist in thyroid neoplasms, and it may be that a combination of both mechanisms is capable of inducing a more complete spectrum of neoplastic phenotypes.

Spinal epidural lipomatosis (SEL) is the abnormal accumulation of normal fat within the spinal canal. It is more frequent in those patients receiving chronic glucocorticoid therapy or in cases of endogenous hypercortisolism states. We report a case of SEL in a patient with metastatic prostate cancer with history of steroid treatment as part of his chemotherapy regimen, presenting with clinical manifestations of partial cord compression. Magnetic resonance imaging images of the lumbar spine revealed the presence of epidural tumor suspicious for metastatic disease. Operative findings were consistent with epidural lipomatosis. Spinal epidural lipomatosis is a rare condition that needs to be included in the differential diagnosis of patients with risk factors, presenting with symptomatic cord compression.

Background: Cancer patients frequently use complementary and alternative medicine (CAM), and spirituality has been associated with CAM use among patients. We evaluated how oncologists’ spirituality and religiosity are associated with personal use and patient recommendations for CAM. Methods: A survey was mailed to 1000 medical oncologists in the United States. The questionnaire asked about oncologists’ approaches to CAM use by patients, focusing on the use of herbs and supplement (HS), and about religiosity and spirituality. Results: Of 937 deliverable questionnaires, 392 were returned (response rate 42%). Respondents were mostly men (71%) and Caucasian (76%), with a median age of 48. Approximately 16% reported no religion, 19% Jewish, 24% Catholic, 28% Christian, and 13% other religions. Eighteen percent reported attending religious services at least once a week, including 15% who attend several times per week. Twenty-eight percent reported high theological pluralism (skepticism regarding whether one religion is comprehensively and uniquely true); 58% described themselves as moderately or very spiritual. Self-reported spirituality and religious service attendance were associated with using CAM personally and recommending HS to patients. In multivariate analyses, moderate-high spirituality and attending religious services less than monthly was positively associated with personal use of CAM: odds ratio (OR) = 3.10 (confidence interval [CI] = 1.5-6.5) and OR = 3.04 (CI = 1.5-6.6), respectively. Physicians with moderate to high spirituality were more likely to report recommending CAM in general (OR = 3.07, CI = 1.3-7.1), but less likely to report recommending HS (OR = 0.33, CI = 0.14-0.75). Conclusion: Self-reported spirituality is a significant factor among US oncologists’ decision to use CAM and recommend CAM to patients.

In Palliative Medicine, symptom management is a clinical priority and one of the key skill sets of the palliative specialist. Symptom control principles have been derived from clinical practice in cancer pain management. They can also be applied to other cancer symptoms, and systematic application will help improve quality of life (QOL). They require a diagnosis of the underlying etiology, individualization of symptom therapy, a systematic approach to management, and therapeutic clarity and simplicity. There are 20 principles that have been identified as helpful to guide the clinical practice of symptom control in advanced cancer.
