Randomized controlled trial of acupuncture for prevention of radiation-induced xerostomia among patients with nasopharyngeal carcinoma
ABSTRACT Xerostomia (dry mouth) after head/neck radiation is a common problem among cancer patients, and available treatments are of little benefit. The objective of this trial was to determine whether acupuncture can prevent xerostomia among head/neck patients undergoing radiotherapy.
A randomized, controlled trial among patients with nasopharyngeal carcinoma was conducted comparing acupuncture to standard care. Participants were treated at Fudan University Shanghai Cancer Center, Shanghai, China. Forty patients were randomized to acupuncture treatment and 46 to standard care. Patients were treated 3×/wk on the same days they received radiotherapy. Subjective measures included the Xerostomia Questionnaire and MD Anderson Symptom Inventory-Head and Neck (MDASI-HN). Objective measures were unstimulated and stimulated whole salivary flow rates. Patients were followed for 6 months after the end of radiotherapy.
Xerostomia Questionnaire scores for acupuncture were statistically significantly lower than for controls starting in week 3 through the 6 months (P = .003 at week 3, all other P < .0001), with clinically significant differences as follows: week 11, relative risk (RR) 0.63 (95% confidence interval [CI], 0.45-0.87); 6 months, RR 0.38 (95% CI, 0.19-0.76). Similar findings were seen for MDASI-HN scores. Group differences emerged as early as 3 weeks into treatment for saliva (unstimulated whole salivary flow rate, P = .0004), with greater saliva flow in the acupuncture group at week 7 (unstimulated whole salivary flow rate, P < .0001; stimulated whole salivary flow rate, P = .002) and 11 (unstimulated whole salivary flow rate, P < .02; stimulated whole salivary flow rate, P < .03) and at 6 months (stimulated whole salivary flow rate, P < .003).
Acupuncture given concurrently with radiotherapy significantly reduced xerostomia and improved quality of life.

ABSTRACT: Purpose. A "dose bricks" concept has been used to implement nasopharyngeal carcinoma treatment plan; this method specializes particularly in the case with bell shape nasopharyngeal carcinoma case. Materials and Methods. Five noncoplanar fields were used to accomplish the dose bricks technique treatment plan. These five fields include (a) right superior anterior oblique (RSAO), (b) left superior anterior oblique (LSAO), (c) right anterior oblique (RAO), (d) left anterior oblique (LAO), and (e) superior inferior vertex (SIV). Nondivergence collimator central axis planes were used to create different abutting field edge while normal organs were blocked by multileaf collimators in this technique. Results. The resulting 92% isodose curves encompassed the CTV, while maximum dose was about 115%. Approximately 50% volume of parotid glands obtained 10-15% of total dose and 50% volume of brain obtained less than 20% of total dose. Spinal cord receives only 5% from the scatter dose. Conclusions. Compared with IMRT, the expenditure of planning time and costing, "dose bricks" may after all be accepted as an optional implementation in nasopharyngeal carcinoma conformal treatment plan; furthermore, this method also fits the need of other nonhead and neck lesions if organ sparing and noncoplanar technique can be executed.BioMed Research International 05/2014; 2014:720876.

ABSTRACT: This review of radioiodine sialadenitis covers molecular mechanisms, demographics, and analysis of quality of life. Animal and human research addressing salivary gland damage from I131 therapy is reported, and supplemented with relevant studies addressing the effect of external beam therapy. An illustrative case example identifies abnormalities in the histopathology associated with radioiodine sialadenitis. Approaches to preventing and treating radioiodine sialadenitis are discussed.06/2014; 2(2):70-84. DOI:10.1007/s40136-014-0041-1

ABSTRACT: Introduction Acupuncture has potential as a supportive care service for cancer symptom management. However, little is known about patients’ willingness to use acupuncture in the context of conventional cancer care. Methodology We conducted a cross-sectional survey study among patients with cancer during their last week of fractionated/external beam radiotherapy (RT). The main outcome variable was self-reported likelihood of using acupuncture during RT. Knowledge about acupuncture and pain severity was measured along with socio-demographic and clinical variables. Multivariate logistic regression was performed to identify factors associated with willingness to use acupuncture. Results Among the 305 participants, 79 (26.4%) were likely to use acupuncture during RT if such services were offered at a reasonable price, 143 (46.9%) had no knowledge of acupuncture, and 206 (67.6%) reported having pain. In multivariate analyses, non-Whites (adjusted odds ratio [AOR] 1.94, 95% Confidence Interval [CI] 1.06-3.56), and those with pain (AOR 2.52, CI 1.25-5.10) were more interested in using acupuncture. In addition, patients with preexisting knowledge about acupuncture were also more likely to use acupuncture than those without this knowledge (AOR 2.23, CI 1.28-3.88). Conclusions Patients of non-White race, those with pain or those with prior knowledge about acupuncture were more willing to utilize acupuncture during RT. Since half of the patients had no knowledge about acupuncture, interventions to improve patients’ knowledge are needed to facilitate the successful integration of acupuncture into cancer care.European Journal of Integrative Medicine 06/2014; 6(5).
