Nutrition Status and Health-Related Quality of Life Among Outpatients With Advanced Head and Neck Cancer.

This pilot study evaluated nutrition status and health-related quality of life (HRQOL) outcomes among outpatients with head and neck cancer (HNC). Data were collected from 19 patients (18 males, 1 female) during 3 time points: once before chemoradiotherapy (CRT) initiation and 1 and 3 months after CRT. Nutrition status was evaluated using the Scored Patient-Generated Subjective Global Assessment (PG-SGA). Malnutrition was defined as PG-SGA stage B (moderate/suspected malnutrition) or stage C (severely malnourished). HRQOL was assessed through the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its HNC-specific module (QLQ-H&N35). We found that well-nourished patients reported having fewer issues with pain, fatigue, appetite loss, chewing, sticky saliva, coughing, and social eating than those categorized as malnourished (P < .05). The association between the global quality-of-life score and PG-SGA score was statistically significant but weak in strength (r = -0.37, P = .012). Although PG-SGA identified 70% as either moderately or severely malnourished before treatment initiation, the mean body mass index was in the overweight category (29 ± 5 kg/m2 ). Compared with pretreatment, patients reported more severe problems with chewing, swallowing, sticky saliva, dry mouth, speech, social eating, and taste and smell sensations at 1-month follow-up, although issues with dry mouth persisted 3 months post treatment (P = .003). In conclusion, malnourished patients reported having worse HRQOL symptoms compared with well-nourished patients. Routine nutrition and psychosocial assessment through PG-SGA and EORTC tools might help identify patients in need of nutrition and psychosocial care.

Malnutrition Identified by the Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition Consensus Criteria and Other Bedside Tools Is Highly Prevalent in a Sample of Individuals Undergoing Treatment for Head and Neck Cancer.

BACKGROUND: Using the Academy of Nutrition and Dietetics and American Society for Parenteral and Enteral Nutrition (Academy/ASPEN) Consensus malnutrition definition, we estimated malnutrition prevalence in a sample of individuals with head and neck cancer (HNC) and compared it with the Patient-Generated Subjective Global Assessment (PG-SGA). We also investigated the utility of the 50-kHz phase angle (PA) and 200-kHz/5-kHz impedance ratio (IR) to identify malnutrition. MATERIALS AND METHODS: Nineteen individuals (18 males, 1 female) scheduled to undergo chemoradiotherapy were seen at 5 time points during and up to 3 months after treatment completion. Multiple-frequency bioelectrical impedance analysis, PG-SGA, nutrition-focused physical examination, anthropometry, dietary intake, and handgrip strength data were collected. RESULTS: Using the Consensus, 67% were found to be malnourished before treatment initiation; these criteria diagnosed malnutrition with overall good sensitivity (94%) and moderate specificity (43%) compared with PG-SGA. Over all pooled observations, "malnourished" (by Consensus but not PG-SGA category) had a lower mean PA (5.2 vs 5.9; P = .03) and higher IR (0.82 vs 0.79; P = .03) than "well-nourished" categorizations, although the clinical relevance of these findings is unclear. PA and IR were correlated with higher PG-SGA score (r = -0.35, r = 0.36; P < .01) and handgrip strength (r = 0.48, r = -0.47; P < .01). CONCLUSION: The Academy/ASPEN Consensus and the PG-SGA were in good agreement. It is unclear whether PA and IR can be used as surrogate markers of nutrition status or muscle loss.

Phase I trial of low-dose oral Clofarabine in myelodysplastic syndromes patients who have failed frontline therapy.

We investigated protracted low-dose oral Clofarabine for the treatment of myelodysplastic syndromes (MDS). Adults with an International Prognostic Scoring System (IPSS) score of INT-1 or higher who had failed first line therapy were eligible. INT-1 patients had to be transfusion-dependent. We started with oral Clofarabine at 5mg (fixed dose) daily for 10 consecutive days on a 28-day cycle. Toxicity prompted a modification to 1mg PO daily for 10 days and then 1mg PO daily for 7 days. Patients received treatment indefinitely until loss of response or unacceptable toxicity. Nine patients (5 women) were enrolled and evaluable (median age 65 years; range 55-81). A 10-day regimen of oral Clofarabine at 5mg/day induced Grade IV pancytopenia. A dose of 1 mg/day for 7/28 days was very well tolerated without significant toxicity. Three patients had responses (2 with responses lasting up to 21 and 51 cycles) defined as stable disease in spite of no significant change on bone marrow evaluation. Low-dose oral Clofarabine (1mg daily for 7/28 days) proved both effective and safe for patients with MDS who had failed prior therapy. This patient population is particularly sensitive to more protracted Clofarabine treatment schedules.

Early diagnosis of intravascular large B-cell lymphoma: clues from routine blood smear morphologic findings.

Intravascular large B-cell lymphoma (IVLBCL) is a mature B-cell neoplasm characterized by malignant lymphoid cells within the lumina of blood vessels and capillaries. Given its varied and nonspecific clinical manifestation, this aggressive disease is often not diagnosed until an advanced clinical stage or even at autopsy. This case highlights a patient presenting with autoimmune hemolytic anemia (AIHA) and fevers. Atypical circulating cells on a screening peripheral smear lead to flow cytometric studies highlighting an increase in large, light chain restricted CD20 positive cells. A diagnostic bone marrow biopsy was performed and trephine cores demonstrated predominantly intrasinusoidal lymphoma cells. In conjunction with additional immunophenotypic data, these studies strongly supported a diagnosis of IVLBCL. Judicious use of flow cytometry and morphology resulted in an early-stage diagnosis and likely contributed to the patient's current complete remission status following anti-CD20 therapy. Differential diagnoses for this presentation are discussed in light of serologic, immunophenotypic, histologic, and cytogenetic findings.
